               CALVERT NATIONAL MUNICIPAL INTERMEDIATE FUND
             4550 Montgomery Avenue, Bethesda, Maryland 20814
==========================================================================


INTRODUCTION TO THE FUNDS

The Calvert National  Municipal  Intermediate Fund ("National  Municipal")
seeks to earn the highest  level of interest  income  exempt from  federal
income  taxes  as  is  consistent  with  prudent  investment   management,
preservation   of   capital,   and  the  stated   quality   and   maturity
characteristics.

The  state-specific  Calvert Municipal  Intermediate Funds ("State Funds")
seek to earn the highest  level of  interest  income  exempt from  federal
and specific state income taxes as is consistent  with prudent  investment
management,  preservation of capital,  and the stated quality and maturity
characteristics.

   
The National Municipal and the State Funds  (collectively,  the "Funds" or
"Municipal  Funds") each invest in nondiversified  portfolios of municipal
obligations,  including  some with  interest  that may be  subject  to the
federal alternative minimum tax. The average  dollar-weighted  maturity of
investments  is between 3 and 10 years.  The net asset  value per share of
each  Fund will  fluctuate  in  response  to  changes  in the value of its
investments.
    

PURCHASE INFORMATION

Each  Municipal  Fund  offers two classes of shares,  each with  different
expense levels and sales  charges.  You may choose to purchase (i) Class A
shares,  with a sales  charge  imposed at the time you purchase the shares
("front-end  sales  charge");  or (ii) Class C shares which impose neither
a front-end sales charge nor a contingent  deferred sales charge.  Class C
shares  are not  available  through  all  dealers.  Class C shares  have a
higher  level of  expenses  than  Class A shares,  including  higher  Rule
12b-1  fees.  These  alternatives  permit  you to  choose  the  method  of
purchasing  shares  that  is most  beneficial  to  you,  depending  on the
amount  of the  purchase,  the  length  of time  you  expect  to hold  the
shares,  and other  circumstances.  See  "Alternative  Sales  Options" for
further details.

          B.   Annual Fund Operating Expenses.  Management Fees are paid by   
 the Funds to Calvert  Asset  Management  Company,  Inc.  for  managing the   
 investments  and  business  affairs  of each  Fund  and  paid  to  Calvert   
 Administrative  Services  Company,  Inc. All expense  ratios,  other than   
 those  for  National  Municipal  and  California,  have been  restated  to   
 reflect  expenses  anticipated  for fiscal year 1996. The Funds will incur   
 Other   Expenses   for   maintaining   shareholder   records,   furnishing   
 shareholder  statements and reports,  and other services.  Management Fees   
 and Other  Expenses  have  already  been  reflected in the share price and   
 are not  charged  directly  to  individual  shareholder  accounts.  Please   
 refer to "Management of the Funds" for further information.                  
                                                                               
          The National  Municipal  Intermediate  Fund commenced  operations    
on September 30, 1992,  and the California  Fund  commenced  operations on 
 May 29,  1992.  The  Maryland,  Michigan,  New  York  and  Virginia  Funds    
commenced  operation   September  30,  1993.  The  Arizona,   Florida  and    
Pennsylvania  Funds commenced  operation  December 31, 1993. For the first
five  years of  operation  of each  Fund,  Class A Rule 12b-1 fees will be
limited  to  0.15%.  The  Advisor  may  voluntarily  defer  fees or assume 
expenses  of the Funds.  If the  Advisor  had not done so for fiscal  year 
1995,  Management  Fees for all the  Municipal  Intermediate  Funds  would 
have been  0.70%.  The  following  table  shows what Total Fund  Operating 
Expenses  would have been,  per class,  without the voluntary  deferral of      
fees or reimbursement of expenses:

       The Investment  Advisory  Agreement provides that the Advisor may
ter, to the extent  permitted by law,  recapture any fees it deferred or
penses it assumed during the two prior years;  provided,  however,  that
tal  Annual  Operating  Expenses for each Fund shall not exceed 2.00% of
average  net  assets  during  any  year in which  the  Advisor  elects to 
exercise  the  recapture   provision.   The  above  table  reflects  these
agreements.


     The Funds' Rule 12b-1 fees include an  asset-based  sales charge.         
Thus,  it is possible  that  long-term  shareholders  in the Funds may pay    
in total sales  charges than the economic  equivalent  of the maximum          
front-end sales charge  permitted by rules of the National  Association
of Securities Dealers, Inc.

INVESTMENT OBJECTIVE AND POLICIES

Investment Objectives

National  Municipal  seeks to earn the highest  level of  interest  income
exempt  from  federal   income  taxes  as  is   consistent   with  prudent
investment  management,  preservation  of  capital,  and the  quality  and
maturity objectives of the Fund.

   
National Municipal will invest at least 65% of its total assets in
municipal obligations
 .
National   Municipal  is  a   nondiversified  (effective upon shareholder
approval) mutual  fund  that  invests primarily  in  municipal   obligations  
with  interest   that,  for  most investors,  is exempt from federal  income 
tax.  Municipal  obligations in which the Series may  invest  include,  but
are not  limited  to,  general obligation  bonds and notes of state and local 
issuers,  revenue bonds of various  transportation,  housing,  utilities  
(e.g.,  water  and  sewer), hospital  and  other  state  and  local  
government  authorities,  tax and revenue   anticipation  notes  and  bond  
anticipation  notes,   municipal leases,  and certificates of participation  
therein,  and private activity bonds.  See further  description  below and 
in the Statement of Additional Information.  The  municipal  obligations  
are  fixed and  variable  rate. Fixed  rate  investments  are  limited  to  
obligations   normally  having remaining  maturities of 12 years or less;  
variable rate  investments may have longer  maturities.  The  average  
dollar-weighted  maturity  will be between 3 and 10 years.  Because  the Fund
may invest in private  activity bonds,  a  portion  of  its  dividends  may  be
subject  to  the  federal alternative minimum tax. See "Dividends and Taxes."
    

The State Funds seek to earn the highest  level of interest  income exempt
from  federal  and  specific  state  income  taxes as is  consistent  with
prudent investment  management,  preservation of capital,  and the quality
and maturity objectives of each Fund.

The State Funds invest in state-specific municipal obligations.

Each State Fund  invests  primarily  in a  nondiversified  portfolio  of a
specific  state's  municipal  obligations  with  interest  that,  for most
investors,  is exempt from federal and that state's income tax.  Municipal
obligations  in which  the  Funds  invest  are  fixed  and  variable  rate
obligations.   The  Advisor  will  maintain  the  average  dollar-weighted
maturity between 3 and 10 years.

Each State Fund invests at least 65% of its assets in debt obligations
issued by or on behalf of the state for which the Fund is named.

Under  normal  market  conditions,  each State Fund will attempt to invest
at least 65% of its total assets in municipal  obligations  with  interest
that is exempt  from  federal and  specific  state  income tax,  including
those  issued  by or on  behalf  of the  state for which the Fund is named
and its  political  subdivisions.  Each  State  Fund will also  attempt to
invest  its  remaining  assets in these  obligations,  but may  invest the
remaining  assets in municipal  obligations  of other states,  territories
and  possessions  of the United  States,  the  District of  Columbia,  and
their respective  authorities,  agencies,  instrumentalities and political
subdivisions.  Dividends  you receive  from a Fund that are  derived  from
interest on tax-exempt  obligations of other governmental  issuers will be
exempt  from  federal  income  tax,  but will be subject  to state  income
taxes.  Because the State Funds may invest in private  activity  bonds,  a
portion  of  the  Fund's   dividends   may  be  subject  to  the   federal
alternative minimum tax. See "Dividends and Taxes."

Credit Quality

As an operating  policy,  each  Municipal Fund (including National and 
California, effective upon shareholder approval) will invest at least 65% of
its   total   assets   in    investment-grade    municipal    obligations.
Investment-grade  obligations  are those which, at the date of investment,
are  rated  within  the  four  highest   grades   established  by  Moody's
Investors  Services,  Inc.  (Aaa, Aa, A, or Baa) or by Standard and Poor's
Corporation  (AAA,  AA, A, or BBB).  Securities  that are not rated may be
purchased  by  the  Funds  as  part  of  the  65%  total  if  the  Advisor
determines  that  they  are  of  quality  comparable  to  investment-grade
securities.  Bonds  rated BBB or Baa,  while still  considered  investment
grade, have certain  speculative  characteristics  and may be more subject
to changes in economic conditions.

The  remaining  35% of each  Municipal  Fund's total assets (including 
National and California, effective upon shareholder approval) may consist of
noninvestment-grade  municipal  obligations  (rated below Baa or BBB),  or
unrated  obligations  that the Advisor has  determined  are not investment
grade.   With   noninvestment-grade   securities   there   is  a   greater
possibility  that an  adverse  change in the  financial  condition  of the
issuer may affect the  issuer's  ability to pay  principal  and  interest.
There is also a greater  risk,  with  noninvestment-grade  securities,  of
price  declines due to changes in the issuer's  creditworthiness.  Because
the market  for  lower-rated  securities  may be less  active  ("thinner")
than for higher-rated  securities,  market prices may be more volatile and
liquidity in the resale market may be limited.

The credit  quality of municipal  obligations  is  determined by reference
to  a  commercial  credit  rating  service,   such  as  Moody's  Investors
Service,  Inc.  or  Standard  & Poor's  Corporation.  Please  refer to the
Appendix in the Statement of Additional  Information  for a description of
the ratings used by these rating services.  The Funds' Advisor  determines
the credit  quality of unrated  instruments  under the  supervision of the
Funds' Board of  Directors/Trustees.  See  Management of the Funds.  There
is no  limitation  on the  percentage  of assets  that may be  invested in
unrated  obligations,  which may be less liquid than rated  obligations of
comparable quality.

Determinations  as to credit  quality are made at the time of  investment.
If a change in credit quality occurs,  the Advisor,  under the supervision
of the  Fund's  Board of  Directors,  will  consider  whether it is in the
best  interest  of the  Funds'  shareholders  to hold or to dispose of the
obligation.

Variable and Floating Rate Obligations

The Funds may invest in variable and floating rate  obligations.  Variable
rate obligations have a yield that adjusts  periodically  based on changes
in the level of  prevailing  interest  rates.  Floating  rate  obligations
have an  interest  rate tied to a known  lending  rate,  such as the prime
rate, and are  automatically  adjusted when the known rate changes.  These
obligations  lessen the  capital  fluctuations  usually  inherent in fixed
income investments,  which diminishes the risk of capital  depreciation of
portfolio  investments and of the Funds' shares.  However, this also means
that if interest  rates  decline,  a Fund's  yield will  decline,  causing
each Fund and its  shareholders  to forego  the  opportunity  for  capital
appreciation of the portfolio investments.

Demand Notes

Each Fund may invest in floating  rate and  variable  rate  demand  notes.
Demand  notes  provide  that the holder may demand  payment of the note at
its par value plus  accrued  interest by giving  notice to the issuer.  To
ensure the ability of the issuer to make payment  upon such  demand,  such
notes are often  supported  by an  unconditional  bank  letter of  credit.
Notes  with a demand  feature  of more  than  seven  days  are  considered
illiquid  and are subject to purchase  restrictions.  See  "Nonfundamental
Investment Restrictions" in the Statement of Additional Information.

   
Nondiversified

There may be risks associated with each Fund being nondiversified.
Specifically, since a relatively high percentage of the assets of each
Fund may be invested in the obligations of a limited number of issuers,
the value of the shares of each Fund may be more susceptible to any
single economic, political or regulatory event than the shares of a
diversified fund would be.
    

Interest-Rate Risk

All fixed income  instruments are subject to interest-rate  risk; that is,
if the market  interest rates rise, the current  principal value of a bond
will  decline.  In  general,  the longer  the  maturity  of the bond,  the
greater  the  decline  in value.  Because  the Funds'  respective  average
dollar-weighted  maturity  is  between  3 and 10  years,  the  investments
would be expected to be more  affected  than by a rise in market  interest
rates than a short-term  money market fund,  but less  adversely  affected
by a rise in market  interest  rates than those of a fund which invests in
longer-term bonds.

Obligations with Puts Attached

Each Fund has  authority  to  purchase  securities  at a price which would
result in a yield to  maturity  lower than that  generally  offered by the
seller at the time of  purchase,  when it can acquire at the same time the
right to sell the  securities  back to the seller at an agreed on price at
any time  during a stated  period  or on a certain  date.  Such a right is
generally  denoted  as  a  "put."  Puts  may  be  either   conditional  or
unconditional.  Unconditional  puts are readily  exercisable  in the event
of a default  in  payment  of  principal  or  interest  on the  underlying
securities.

Municipal Leases

Each  Fund  may  invest  in  municipal  leases.  A  municipal  lease is an
obligation  of a  government  or  governmental  authority,  not subject to
voter   approval,   used  to  finance   capital   projects  or   equipment
acquisitions  and payable  through  periodic  rental  payments.  There are
additional   risks  inherent  in  investing  in  this  type  of  municipal
security.  Unlike  municipal  notes and  bonds,  where a  municipality  is
obligated  by law to  make  interest  and  principal  payments  when  due,
funding for lease  payments needs to be  appropriated  each fiscal year in
the  budget.  It is  possible  that a  municipality  will not  appropriate
funds for lease  payments.  The Advisor  considers risk of cancellation in
its  investment  analysis.   The  Funds  may  purchase  unrated  municipal
leases.    The   Advisor,    under    supervision   of   the   Boards   of
Directors/Trustees,  is responsible  for determining the credit quality of
such leases on an ongoing  basis.  The Funds will invest only in municipal
leases that meet their  credit  quality  restrictions.  Certain  municipal
leases may be  considered  illiquid  and  subject to the Funds'  limits on
illiquid investments.  The Boards of  Directors/Trustees  have established
guidelines for  determining  whether a lease is liquid.  See the Statement
of  Additional  Information  for the  factors  considered  by the Board in
determining liquidity and valuation of leases.

When-Issued Purchases

New issues of municipal  obligations  are offered on a when-issued  basis;
that is,  delivery and payment for the  securities  normally take place 15
to 45 days after the date of the transaction.  The payment  obligation and
the yield that will be  received on the  securities  are each fixed at the
time the  buyer  enters  into the  commitment.  The  Funds  will only make
commitments  to purchase  such  securities  with the intention of actually
acquiring  the  securities,  but may  sell  these  securities  before  the
settlement  date if it is  deemed  advisable  as a  matter  of  investment
strategy.

Temporary Investments

For  liquidity  purposes or pending the  investment of the proceeds of the
sale of its  shares,  a Fund may  invest in and  derive up to 35% (20% for
National  Municipal and California) of its income from taxable  short-term
money  market  type   investments.   Interest  earned  from  such  taxable
investments  will be  taxable  to you as  ordinary  income  unless you are
otherwise  exempt from taxation.  Such  investments  will be of investment
grade,  or, if unrated,  determined to be of equivalent  credit quality by
the Advisor.

Financial Futures, Options, and Other Investment Techniques

(All Municipal Funds, effective upon shareholder approval for National and 
California).

Each  Municipal  Fund can use various  techniques  to increase or decrease
its  exposure  to  changing  security  prices,  interest  rates,  or other
factors  that  affect  security  values.   These  techniques  may  involve
derivative  transactions  such as buying and  selling  options and futures
contracts  and  leveraged  notes,  entering  into  swap  agreements,   and
purchasing  indexed  securities.  The Funds can use these practices either
as a  substitution  for or as  protection  against an adverse  move in the
Fund's  portfolio  to adjust  the risk and return  characteristics  of the
Fund's portfolio.  If the Advisor judges market conditions  incorrectly or
employs  a  strategy  that  does  not  correlate   well  with  the  Fund's
investments,  or if the  counterparty to the transaction  does not perform
as promised,  these  techniques  could result in a loss.  These techniques
may increase the  volatility of a Fund and may involve a small  investment
of cash  relative to the magnitude of the risk  assumed.  Any  instruments
determined  to be illiquid  are subject to the Fund's 15%  restriction  on
illiquid  securities.  See the  Statement of  Additional  Information  for
more detail about these strategies.

Under certain  circumstances,  the  Municipal  Funds may purchase and sell
certain  financial  futures  contracts  and  certain  options  on  futures
contracts  to hedge  investments  in  municipal  securities.  A  financial
futures  contract  obligates  the seller of a  contract  to deliver -- and
the  purchaser of a contract to take  delivery of -- the type of financial
instrument  covered by the contract.  In the case of  index-based  futures
contracts,  the  obligation  is in  the  form  of a cash  settlement  at a
specific time for a specific price.

The Funds may only  engage in  futures  transactions  for the  purpose  of
hedging their  investments  in municipal  securities  against  declines in
value and to hedge against  increases in the cost of securities  the Funds
intend to purchase.  A sale of financial  futures  contracts may provide a
hedge  against a  decline  in the value of  portfolio  securities  because
such  depreciation  may be offset,  in whole or in part, by an increase in
the  value  of  the  position  in  the  futures  contracts.  Similarly,  a
purchase of financial  futures  contracts  may provide a hedge  against an
increase  in the cost of  securities  intended  to be  purchased,  because
such  appreciation  may be offset,  in whole or in part, by an increase in
the value of the position in the futures contracts.

Types of Futures Contracts Purchased

The  Advisor  intends  to  deal,  on  behalf  of  the  Funds,  in  futures
contracts based on The Bond Buyer  Municipal Bond Index, a  price-weighted
measure  of the  market  value  of 40  large,  recently-issued  tax-exempt
bonds,   and  to  engage  in  transactions  in   exchange-listed   futures
contracts  on U.S.  Treasury  securities.  The  Funds  may also  engage in
transactions  in other  futures  contracts,  such as futures  contracts on
other  municipal  bond  indices  that  become  available,  if the  Advisor
believes  such  contracts  would be  appropriate  for  hedging  the Funds'
investments in municipal securities.

When a Fund  purchases a futures  contract,  it will maintain an amount of
cash, cash  equivalents  (for example,  commercial  paper and daily tender
adjustable  notes) or short-term  high grade fixed income  securities in a
segregated  account  with the  Fund's  custodian,  so that the  segregated
amount  plus the  amount  of  initial  and  variation  margin  held in the
account of its broker  equals the market  value of the  futures  contract,
thereby  ensuring  that the use of such futures  contract is  unleveraged.
It is not  anticipated  that  transactions in futures will have the effect
of increasing portfolio turnover.

Closing out a Futures Position -- Risks

A Fund may close out its  position  in a futures  contract or an option on
a futures  contract  only by entering into an  offsetting  transaction  on
the exchange on which the position  was  established  and only if there is
a  liquid  secondary  market  for  the  futures  contract.  If it  is  not
possible to close a futures  position  entered into by the Fund,  the Fund
could be  required to make  continuing  daily cash  payments of  variation
margin in the event of adverse price  movements.  In such  situations,  if
the Fund has insufficient  cash, it may have to sell portfolio  securities
to  meet  daily   margin   requirements   at  a  time  when  it  would  be
disadvantageous  to do so.  The  inability  to close  futures  or  options
positions  could  have an adverse  effect on the  Fund's  ability to hedge
effectively.  There is also risk of loss by the Fund of margin deposits in
the  event  of  bankruptcy  of a  broker  with  whom  the Fund has an open
position  in  a  futures  contract.  The  success  of a  hedging  strategy
depends on the  Advisor's  ability to predict  the  direction  of interest
rates and other economic  factors.  The  correlation is imperfect  between
movements  in  the  prices  of  futures  or  options  contracts,  and  the
movements of prices of the securities  which are subject to the hedge.  If
a Fund used a futures or options  contract  to hedge  against a decline in
the market,  and the market later advances (or  vice-versa),  the Fund may
suffer a greater loss than if it had not hedged.

Please  refer to the  Statement  of  Additional  Information  for  further
information on futures contracts.

Special considerations regarding single-state municipal obligations

There is risk inherent in investing  primarily in the  obligations  of any
one state,  since  economic and political  changes in the state may affect
those  obligations.  Since each State Fund invests  primarily in municipal
obligations   of  individual   states  and  is  thereby   limited  in  its
alternative  investment  choices,  the  performance of a State Fund may be
affected by local  economic  conditions generally and the fiscal/budgetary
condition of the State and other Municipalities in which a State Fund may
invest.  With  respect to any state,  you should  be aware  that  certain 
proposed  state  or local  constitutional amendments,   legislative  measures, 
executive  orders,   administrative regulations   or  voter   initiatives,  
in  addition  to  local  economic conditions,  could result in adverse  
consequences  affecting  the ability of the state or its  municipalities  to 
meet their obligations in a timely manner, which, in turn, could affect a State
Fund's performance.

Other Policies 

Each Fund may  temporarily  borrow  money  from  banks to meet  redemption
requests,  but such  borrowing may not exceed 10% of the value of a Fund's
total  assets.  The Funds  have  adopted  certain  fundamental  investment
restrictions   which  are   discussed  in  detail  in  the   Statement  of
Additional Information.

YIELD AND TOTAL RETURN

Yield refers to income generated by an investment over a period of time
for each class.

Yield measures the current  investment  performance for each class,  which
is the rate of  income  on  portfolio  investments  divided  by the  share
price.  To  determine  yield,  (1) net  investment  income is  computed by
adding all  investment  income  earned by a Fund over a 30-day  period and
subtracting  expenses,  (2) dividing by the average  number of outstanding
shares  during the period,  and (3)  annualizing  the result  based on the
maximum  offering  price per share on the last day of the  period.  Yields
are calculated  separately for each class according to accounting  methods
that are standardized for all stock and bond funds.

Taxable Equivalent Yield

A Fund may advertise its "taxable  equivalent  yield" for each class.  The
taxable  equivalent  yield is the  yield  that you  would be  required  to
obtain from taxable  investments  to equal the yield of the class,  all or
a portion of which may be exempt from federal  income  taxes.  The federal
taxable  equivalent  yield is  computed  by taking  the  portion  of the a
Fund's yield exempt from regular  federal income tax and  multiplying  the
exempt  yield by a factor  based on a given  income tax rate,  then adding
the  portion of the yield that is not exempt  from such  income  tax.  The
double (combined state and federal)  taxable  equivalent yield is computed
by taking the portion of the a Fund's yield  exempt from  regular  federal
and state  income tax and  multiplying  the exempt yield by a factor based
on a given  income tax rate,  then adding the portion of the yield that is
not exempt  from such income  tax.  The factor  that is used to  calculate
the taxable  equivalent yield is the reciprocal of the difference  between
one and the  applicable  income  tax  rate,  which  will be  stated in the
advertisement.

A Fund may advertise its total return for each class. Total return is
based on historical results and is not intended to indicate future
performance.

Total  return is  calculated  separately  for each class.  It includes not
only the  effect  of  income  dividends  but also any  change in net asset
value,  or principal  amount,  during the stated period.  Total return for
each  class  shows  overall  change in value,  including  changes in share
price  and  assuming  reinvestment  of  all  dividends  and  capital  gain
distributions.   Cumulative  total  return  reflects  performance  over  a
stated  period  of  time.   Average  annual  total  return   reflects  the
hypothetical  annual  compounded  return that would have produced the same
cumulative  total return if performance  had been constant over the entire
period.  Because  average  annual returns tend to smooth out variations in
returns,  you  should  recognize  that  they  are not the  same as  actual
year-by-year  results.  Both  types of  total  return  for  Class A shares
usually will  include the effect of paying a front-end  sales  charge.  Of
course,  total  returns will be higher if sales charges are not taken into
account.  Quotations  of  "return  without  maximum  load" do not  reflect
deduction of the sales charge.  You should  consider these figures only if
you qualify for a reduced  sales  charge,  or for  purposes of  comparison
with comparable  figures which also do not reflect sales charges,  such as
mutual  fund  averages  compiled  by  Lipper  Analytical  Services,   Inc.
Further  information  about  performance is contained in the Annual Report
to Shareholders, which may be obtained without charge.

MANAGEMENT OF THE FUNDS

The Boards of Directors/Trustees supervise the activities and review
contracts with companies that provide the Funds with services.

Calvert Asset Management serves as Advisor to the Funds.

Calvert Asset  Management  Company,  Inc. is each Fund's  Advisor,  and is
entitled  to an  annual  fee,  payable  monthly,  of 0.60% of each  Fund's
average net assets.  The Advisor may in its  discretion and on a voluntary
basis  only,  waive or defer  its fees or  assume  each  Fund's  operating
expenses.  During 1995, National and California each paid investment advisory
fees of 0.60%.  Arizona, Florida, Maryland, Michigan, New York, Pennsylvania, 
and Virginia paid fees of 0.17%, o.27%, 0.27%, 0.31%, 0.23%, 0.22%, and 
0.33%, respectively, and the remainder of each investment advisory fee was 
waived.  The  Investment  Advisory  Agreement  provides that the Advisor
may later, to the extent  permitted by law,  recapture any fees it waived,
or expenses it assumed under this  limitation.  The Advisor  provides each
Fund with investment supervision and management,  administrative  services
and office space;  furnishes  executive and other  personnel to the Funds;
and  pays  the  salaries  and  fees  of  all  Directors/Trustees  who  are
affiliated  persons of the  Advisor.  The  Advisor may also assume and pay
certain  advertising  and  promotional  expenses of the Funds and reserves
the right to  compensate  broker-dealers  in return for their  promotional

SHAREHOLDER GUIDE

Opening An Account

You can buy shares in several ways which are described here and in the
chart on page _______.

An account  application  accompanies  this  prospectus.  A  completed  and
signed  application is required for each new account you open,  regardless
of the method you choose for making your  initial  investment.  Additional
forms  may  be  required  from  corporations,  associations,  and  certain
fiduciaries.  If you have any questions or need extra  applications,  call
your broker,  or Calvert Group at  800-368-2748.  Be sure to specify which
class you wish to purchase.

Alternative Sales Options

The Funds offer two classes of shares:

Class A Shares - Front End Load Option

Class A shares  are sold  with a  front-end  sales  charge  at the time of
purchase.  Class A shares are not subject to a sales  charge when they are
redeemed.

Class C shares - Level Load Option

Class C shares  are sold  without a sales  charge at the time of  purchase
or redemption.

Class C shares have higher expenses

   
Each  Fund  bears  some  of  the  costs  of  selling   its  shares   under
Distribution  Plans  adopted  with  respect  to its  Class  A and  Class C
shares  pursuant  to Rule  12b-1  under the 1940 Act.  Payments  under the
Class A  Distribution  Plan are currently  limited to up to 0.15% annually
of the  average  daily net  asset  value of Class A  shares,  although  no
Class A  Distribution  Plan fees are being paid by the Funds at this time.
The  Class C  Distribution  Plan  provides  for the  payment  of an annual
distribution  fee to  CDI of up to  0.55%,  plus  a  service  fee of up to
0.25%, for a total of 0.80%, of the average daily net assets of Class C.
    

Considerations for deciding which class of shares to buy

Income  distributions  for Class A shares  will  probably  be higher  than
those  for  Class C  shares,  as a  result  of the  distribution  expenses
described  above.   (See  also  "Yield  and  Total  Return.")  You  should
consider  Class A shares if you qualify for a reduced  sales  charge under
Class A or if you plan to hold the shares  for  several  years.  The Funds
will not  normally  accept any purchase of Class C shares in the amount of
$1,000,000 or more.

Class A Shares

Class A shares are  offered  at net asset  value  plus a  front-end  sales
charge as follows:

by CDI in one of the following  methods:  (1) CDI may pay  broker-dealers,
on a  monthly  basis  for  12  months,  an  annual  rate  of up to  0.36%.
Payments   will   be   made   less   redemptions;   or  (2)  CDI  may  pay
broker-dealers  0.25%  of  the  amount  of  the  purchase;   however,  CDI
reserves  the right to recoup any portion of the amount paid to the dealer
if the  investor  redeems  some or all of the shares from the Funds within
thirteen months of the time of purchase.  Quarterly trailing  compensation
will begin in the thirteenth month.
    

Sales  charges on Class A shares may be reduced or  eliminated  in certain
cases. See Exhibit A to this prospectus.

The  sales  charge  is paid to CDI,  which  in turn  normally  reallows  a
portion to your  broker-dealer.  Upon written  notice to dealers with whom
it has  dealer  agreements,  CDI may  reallow  up to the  full  applicable
sales  charge.  Dealers to whom 90% or more of the entire  sales charge is
reallowed may be deemed to be  underwriters  under the  Securities  Act of
1933.

In  addition  to any  sales  charge  reallowance  or  finder's  fee,  your
broker-dealer,   or  other  financial  service  firm  through  which  your
account  is  held,  currently  will be paid  periodic  service  fees at an
annual rate of up to 0.15% of the  average  daily net asset value of Class
A shares held in accounts maintained by that firm.

Class A Distribution Plan

   
Each Fund has  adopted a  Distribution  Plan with  respect  to its Class A
shares (the "Class A  Distribution  Plan"),  which  provides for payments,
which are limited to an annual  rate of 0.15% for each  Fund's  first five
years of operation  (and 0.25%  thereafter) of the average daily net asset
value  of  Class  A  shares,   to  pay   expenses   associated   with  the
distribution  and  servicing of Class A shares.  Amounts paid by the Funds
to CDI  under  the Class A  Distribution  Plan are used to pay to  dealers
and others,  including  CDI  salespersons  who service  accounts,  service
fees,  and to  pay  CDI  for  its  marketing  and  distribution  expenses,
including,  but not  limited  to,  preparation  of  advertising  and sales
literature  and the printing and mailing of  prospectuses  to  prospective
investors.  During  the 1995  fiscal  period,  the  Funds  paid no Class A
Distribution Plan expenses.
    

Class C Shares

Class C shares are not available  through all dealers.  Class C shares are
offered  at net  asset  value,  without  a  front-end  sales  charge  or a
contingent  deferred sales charge.  Class C expenses are higher than those
of Class A.

Class C Distribution Plan

   
The Funds have  adopted a  Distribution  Plan with  respect to its Class C
shares (the "Class C Distribution  Plan"),  which provides for payments at
an annual  rate of up to 0.80% of the  average  daily  net asset  value of
Class C shares,  to pay  expenses of the  distribution  and  servicing  of
Class C shares.  Amounts paid by the Funds under the Class C  Distribution
Plan are  currently  used by CDI to pay  dealers and other  selling  firms
compensation  at an  annual  rate of up to  0.75%,  which  may  include  a
service fee, as described  above under "Class A Distribution  Plan," of up
to 0.25% of the average  daily net asset value of the accounts  maintained
by that  firm.  During  the 1995  fiscal  period,  each of the Funds  paid
Class C Distribution Plan expenses of 0.80%.
    

Arrangements with Broker-Dealers and Others (all classes)

CDI may also pay additional  concessions,  including non-cash  promotional
incentives,   such  as   merchandise  or  trips,   to  dealers   employing
registered  representatives  who  have  sold  or are  expected  to  sell a
minimum  dollar  amount  of shares  of the  Funds  and/or  shares of other
Funds  underwritten  by  CDI.  CDI may  make  expense  reimbursements  for
special  training of a dealer's  registered  representatives,  advertising
or  equipment,  or to defray  the  expenses  of sales  contests.  Eligible
marketing  and  distribution  expenses may be paid  pursuant to the Funds'
Rule 12b-1 Distribution Plans.

Dealers or others may receive  different levels of compensation  depending
on which class of shares they sell.  Payments  pursuant to a  Distribution
Plan are included in the operating expenses of the class.

Each of the  Distribution  Plans may be  terminated  at any time by a vote
of the  Independent  Directors/Trustees  or by vote of a  majority  of the
outstanding voting shares of the respective class.

NET ASSET VALUE

How share price is determined.

Net  asset  value  ("NAV")  refers  to  the  worth  of one  share.  NAV is
computed  separately  for each class by adding the value of all  portfolio
holdings and other  assets,  deducting  liabilities  and then dividing the
result  by the  number  of shares  outstanding.  The NAV will  vary  daily
based on the market  values of the Funds'  investments.  These  values are
calculated  at the close of each business day,  which  coincides  with the
closing of the regular  session of the New York Stock  Exchange  (normally
4:00 p.m.  Eastern  time).  The Funds are open for  business  each day the
New York Stock Exchange is open.

All share  purchases  will be  confirmed  and  credited to your account in
full and fractional shares (rounded to the nearest 1/1000 of a share).

Portfolio   securities  and  other  assets  are  valued  based  on  market
quotations.  If quotations are not  available,  securities are valued by a
method that the appropriate  Fund's Board of  Directors/Trustees  believes
accurately reflects fair value.

WHEN YOUR ACCOUNT WILL BE CREDITED

Before you buy shares, please read the following information to make
sure your investment is accepted and credited properly.

Your  purchase will be processed at the net asset value  calculated  after
your order is  received  and  accepted.  If your  purchase  is received by
4:00 p.m.  Eastern  time,  your  account  will be  credited  on the day of
receipt.  If your  purchase is received  after 4:00 p.m.  Eastern time, it
will be credited the next  business day.  Your  purchases  must be made in
U.S.  dollars  and  checks  must be drawn on U.S.  banks.  No cash will be
accepted.  Each Fund  reserves the right to suspend the offering of shares
for a period of time or to reject any  specific  purchase  order.  If your
check does not clear,  your  purchase  will be  cancelled  and you will be
charged a $10 fee plus costs  incurred by the Funds.  When you purchase by
check or with Calvert  Money  Controller,  those funds will be on hold for
10  business   days  from  the  date  of  receipt.   During  that  period,
redemptions  against  those  funds  will not be  honored.  To  avoid  this
collection  period,  you can wire federal funds from your bank,  which may
charge you a fee.

Certain financial  institutions or  broker-dealers  that have entered into
a sales  agreement  with the  Distributor  may  enter  confirmed  purchase
orders on behalf of  customers by phone,  with payment to follow  within a
number of days of the order as  specified  by the  program.  If payment is
not received in the time  specified,  the financial  institution  could be
held liable for resulting fees or losses.

EXCHANGES

You may exchange shares of your Fund for shares of the same class of
other Calvert Group Funds.

If your investment  goals change,  the Calvert Group Family of Funds has a
variety of  investment  alternatives  that  includes  common  stock funds,
tax-exempt  and  corporate  bond  funds,   and  money  market  funds.  The
exchange  privilege  is a  convenient  way to buy shares in other  Calvert
Group  Funds in order to  respond  to  changes  in your goals or in market
conditions.  However,  to protect your Fund's  performance  and to prevent
additional   costs,   Calvert  Group   discourages   frequent   exchanges.
Shareholders  (and  those  managing   multiple   accounts)  who  make  two
purchases and two exchange  redemptions  of shares of the same fund during
any  6-month  period  will  be  given  written  notice  that  they  may be
prohibited  from  making  additional  investments.  These  policies do not
prohibit  you from  redeeming  shares  of the  funds  and do not  apply to
trades solely among money market  funds.  Before you make an exchange from
a Fund or Portfolio, please note the following:

   
Each exchange represents the sale of shares of one Fund and the purchase
of shares of another. Thus, you could realize a taxable gain or loss.
    

o        Call  your  broker or a Calvert  representative  for  information
and a  prospectus  for any of  Calvert's  other Funds  registered  in your
state.  Read the  prospectus of the Fund or Portfolio  into which you want
to exchange for relevant information, including class offerings.

o        Complete and sign an  application  for an account in that Fund or
Portfolio,  taking care to register  your new account in the same name and
taxpayer  identification  number  as  your  existing  Calvert  account(s).
Exchange  instructions  may  then  be  given  by  telephone  if  telephone
redemptions  have been  authorized  and the shares are not in  certificate
form.  See  "Selling  Your  Shares"  and "How to Sell  Your  Shares  -- By
Telephone, and -- By Exchange To Another Calvert Group Fund."

o        Shares on which you have  already  paid a sales charge at Calvert
Group and shares acquired by  reinvestment of dividends and  distributions
may be exchanged into another Fund at no additional charge.

   
For  purposes of the exchange  privilege,  effective  July 31,  1996,  the
Fund is related to Summit Cash Reserves  Fund by  investment  and investor
services.  Each  Fund  reserves  the  right to  terminate  or  modify  the
exchange privilege in the future with 60 days' written notice.
    

OTHER CALVERT GROUP SERVICES

Calvert Information Network

24 hour yield and prices

Calvert Group has a  round-the-clock  telephone service that lets existing
customers  use a push button  phone to obtain  prices,  yields and account
balances.  Complete  instructions  for  this  service  may be found on the
back of each statement.

Calvert Money Controller

Calvert Money Controller eliminates the delay of mailing a check or the
expense of wiring funds. You can request this free service on your
application.

This  service  allows you to  authorize  electronic  transfers  of money to
purchase  or  sell  shares.  You  use  Calvert  Money  Controller  like  an
"electronic  check"  to move  money  ($50 to  $300,000)  between  your bank
account  and your Fund  account  with one phone  call.  Allow two  business
days after the call for the  transfer  to take  place;  for money  recently
invested,  allow  normal  check  clearing  time  (up to 10  business  days)
before redemption proceeds are sent to your bank.

You may also arrange systematic monthly or quarterly  investments  (minimum
$50)  into  your  Calvert   Group   account.   After  you  give  us  proper
authorization,  your bank account will be debited to purchase  Fund shares.
A debit  entry  will  appear on your bank  statement.  If you would like to
make  arrangements  for systematic  monthly or quarterly  redemptions  from
your Calvert  account,  call your broker or Calvert for a Money  Controller
Application.

Telephone Transactions

Calvert Group may record all telephone calls.

You may purchase,  redeem, or exchange shares,  wire funds and use Calvert
Money  Controller  by  telephone  if  you  have   pre-authorized   service
instructions.  You  automatically  have  telephone  privileges  unless you
elect  otherwise.  The Funds,  the transfer agent and their affiliates are
not liable if they act in good faith on  telephone  instructions  relating
to  your  account,  so  long  as  they  follow  reasonable  procedures  to
determine that the telephone  instructions  are genuine.  Such  procedures
may include  recording  the  telephone  calls and  requiring  some form of
personal  identification.  You should  verify the  accuracy  of  telephone
transactions immediately upon receipt of your confirmation statement.

Optional Services

Complete the application for the easiest way to establish services.

The easiest way to  establish  optional  services  on your  Calvert  Group
account  is to select  the  options  you  desire  when you  complete  your
account  application.  If you wish to add  other  options  later,  you may
have  to  provide  us  with   additional   information   and  a  signature
guarantee.  Please  call your  broker or  Calvert  Investor  Relations  at
800-368-2745 for further  assistance.  For our mutual  protection,  we may
require a signature guarantee on certain written transaction  requests.  A
signature  guarantee verifies the authenticity of your signature,  and may
be obtained  from any bank,  savings and loan  association,  credit union,
trust  company,   broker-dealer   firm  or  member  of  a  domestic  stock
exchange. A signature guarantee cannot be provided by a notary public.

Householding of General Mailings

   
Householding  reduces  Fund  expenses  and  saves  paper and trees for the
environment.
    

If you have  multiple  accounts  with  Calvert,  you may receive  combined
mailings of some shareholder  information,  such as semi-annual and annual
reports.  Please contact  Calvert  Investor  Relations at  800-368-2745 to
receive additional copies of information.

Special Services and Charges

The Funds pay for shareholder  services but not for special  services that
are  required by a few  shareholders,  such as a request for a  historical
transcript  of an account.  You may be required to pay a research  fee for
these special services.

If you are  purchasing  shares of a Fund  through a  program  of  services
offered by a securities dealer or financial  institution,  you should read
the  program  materials  in  conjunction  with  this  Prospectus.  Certain
features may be modified in these  programs,  and  administrative  charges
may be imposed  by the  broker-dealer  or  financial  institution  for the
services rendered.

SELLING YOUR SHARES

You may redeem all or a portion of your shares on any business  day.  Your
shares  will be  redeemed  at the next net asset  value  calculated  after
your redemption  request is received and accepted.  See below for specific
requirements   necessary   to  make  sure  your   redemption   request  is
acceptable.  Remember  that your Fund may hold  payment on the  redemption
of your shares until it is reasonably  satisfied that  investments made by
check or by Calvert Money  Controller have been collected  (normally up to
10 business days).

Redemption Requirements to Remember

To ensure acceptance of your redemption request, please follow the
procedures described here and below.

Once your shares are  redeemed,  the proceeds will normally be sent to you
on  the  next  business  day,  but  if  making  immediate   payment  could
adversely  affect a Fund, it may take up to seven (7) days.  Calvert Money
Controller  redemptions  generally  will be credited to your bank  account
on the  second  business  day after  your  phone  call.  When the New York
Stock  Exchange is closed (or when trading is  restricted)  for any reason
other  than its  customary  weekend  or  holiday  closings,  or under  any
emergency  circumstances  as  determined  by the  Securities  and Exchange
Commission, redemptions may be suspended or payment dates postponed.

Minimum account balance is $1,000.

Please  maintain  a balance in your  account of at least  $1,000 per Fund,
per class.  If, due to  redemptions,  your account falls below $1,000,  it
may be closed  and the  proceeds  mailed to you at the  address of record.
You will be given  notice that your  account  will be closed after 30 days
unless you make  additional  investments to increase your account  balance
to the $1,000 minimum.

Controller.  All  requests  must  received  by  4:00  p.m.  Eastern  time.
Accounts cannot be closed by this service.

Group Fund or  Portfolio.  You can only  exchange  between  accounts  with

previously   authorized   with   a   signature-guaranteed    letter.   See
"Exchanges."

Systematic Check Redemptions

If you  maintain  an account  with a balance  of $10,000 or more,  you may
have up to two (2)  redemption  checks for a fixed  amount  sent to you on
the 15th of each month  simply by sending a letter  with all  information,
including your account number,  and the dollar amount ($100  minimum).  If
you would like a regular  check  mailed to another  person or place,  your
letter must be signature guaranteed.

Through your Broker

If your  account  is  held in your  broker's  name  ("street  name"),  you
should  contact  your  broker  directly  to  transfer,  exchange or redeem
shares.

DIVIDENDS AND TAXES

Dividends from net investment income are paid monthly.

Net  investment  income  consists  of  interest  income,   net  short-term
capital  gains,  if any, and dividends  declared and paid on  investments,
less  expenses.  Each  year,  the Funds  distribute  substantially  all of
their net investment  income to  shareholders.  Dividend and  distribution
payments will vary between classes;  dividend  payments are anticipated to
generally be higher for Class A shares.

Dividend payment options

   
Dividends  and  any  distributions  are  automatically  reinvested  at net
asset  value in  additional  shares of the Funds  unless you elect to have
the  dividends  of $10 or more paid in cash (by check or by Calvert  Money
Controller).  Dividends and  distributions  may be automatically  invested
in an identically  registered  account with the same account number in any
other  Calvert  Group Fund or Portfolio at net asset value.  If reinvested
in the same  Fund  account,  new  shares  will be  purchased  at net asset
value on the  reinvestment  date,  which is generally 1 to 3 days prior to
the  payment  date.  You  must  be a  shareholder  on the  record  date to
receive  dividends.  You must  notify  the Funds in  writing  prior to the
record  date  to  change  your  payment  options.  If you  elect  to  have
dividends and/or  distributions  paid in cash, and the U.S. Postal Service
cannot deliver the check,  or if it remains  uncashed for six months,  it,
as well as future  dividends  and  distributions,  will be  reinvested  in
additional shares.
    

"Buying a Dividend"

At the  time of  purchase,  the  share  price  of your  Fund  may  reflect
undistributed  income,   capital  gains  or  unrealized   appreciation  of
securities.  Any income or capital  gains  from  these  amounts  which are
later  distributed  to you are fully  taxable.  On the  record  date for a
distribution,  your  Fund's  share  value is  reduced by the amount of the
distribution.  If you buy shares just  before the record  date  ("buying a
dividend")  you will pay the full price for the shares and then  receive a
portion of the price back as a taxable distribution.

Federal Taxes

Dividends  derived  from  interest  on  municipal  obligations  constitute
exempt-interest  dividends,  on  which  you are  not  subject  to  federal
income tax.  However,  dividends  which are from taxable  interest and any
distributions  of short-term  capital gains are taxable to you as ordinary
income.  If the Funds make any  distributions of long-term  capital gains,
then these are taxable to you as long-term  capital  gains,  regardless of
how long you held your shares.

If any taxable  income or gains are paid, in January,  the Funds will mail
you Form 1099-DIV  indicating  the federal tax status of dividends and any
capital gain distributions paid to you by the Funds during the past year.

You may realize a capital gain or loss when you redeem (sell) or
exchange shares.

If you sell or  exchange  your  shares you will have a short or  long-term
capital  gain or loss,  depending  on how long you  owned the  shares.  In
January,  your Fund  will mail you Form  1099-B  indicating  the  proceeds
from  all  sales,  including  exchanges.   You  should  keep  your  annual
year-end  account  statements to determine the cost (basis) of your shares
to report on your tax returns.

Alternative Minimum Tax

Each Fund may invest in  municipal  obligations,  such as certain  private
activity  bonds,  that earn  interest  subject to the federal  alternative
minimum tax ("AMT").  AMT is a method of  computing  tax that helps ensure
that certain  corporations  and  high-income  individual  taxpayers  pay a
minimum   amount  of  tax.  Since  the  Funds  are  likely  to  invest  in
obligations  that are  taxable  under the AMT method of  computing  income
tax,  taxpayers  who are  required  to pay AMT may not  receive as high an
after-tax  yield as  investors  who are not  subject  to AMT.  You  should
consult your tax advisor if you have any questions regarding your status.

State Taxes

To the extent that  exempt-interest  dividends  are derived from  earnings
attributable  to  municipal  obligations  of a state,  they  will  also be
exempt  from  state and  local  personal  income  tax in that  state.  The
dividends  may be subject to franchise  taxes and  corporate  income taxes
if  received  by a  corporation  subject to such  taxes.  A letter will be
mailed to you shortly after  year-end  informing you of the  percentage of
exempt-interest   dividends  derived  from  earnings  on  state  municipal
obligations.

Taxpayer Identification Number

Federal law  requires  that you provide your  correct  Social  Security or
Taxpayer  Identification  Number ("TIN") on a signed certified application
or Form W-9. If not  provided,  the Funds may be required to withhold  31%
of any  dividends or  redemptions,  and you may be subject to a fine.  You
will also be  prohibited  from opening  another  account by  exchange.  If
this TIN  information  is not  received  within 60 days after your account
is  established,  your  account  may be redeemed at the current NAV on the
date of  redemption.  The  Funds  reserve  the  right  to  reject  any new
account or any purchase order for failure to supply a certified TIN.

                                EXHIBIT A

REDUCED SALES CHARGES (CLASS A ONLY)

You may qualify for a reduced sales charge through several purchase
plans available. You must notify the Funds at the time of purchase to
take advantage of the reduced sales charge.

Right of Accumulation
The  sales  charge  is  calculated  by taking  into  account  not only the
dollar  amount of a new  purchase  of shares,  but also the higher of cost
or current  value of shares  previously  purchased in Calvert  Group Funds
that impose  sales  charges.  This  automatically  applies to your account
for each new purchase.

Letter of Intent
If you plan to  purchase  $50,000 or more of Fund  shares over the next 13
months,  your sales  charge may be reduced  through a "Letter of  Intent."
You pay the lower sales  charge  applicable  to the total  amount you plan
to invest  over the  13-month  period,  excluding  any money  market  fund
purchases.  Part of your shares will be held in escrow,  so that if you do
not  invest the amount  indicated,  you will have to pay the sales  charge
applicable   to  the   smaller   investment   actually   made.   For  more
information, see the Statement of Additional Information.

Group Purchases
If you are a member of a qualified  group,  you may purchase shares of the
Funds at the  reduced  sales  charge  applicable  to the group  taken as a
whole.  The sales  charge is  calculated  by taking into  account not only
the  dollar  amount of the  shares  you  purchase,  but also the higher of
cost or current value of shares  previously  purchased and currently  held
by other members of your group.

A "qualified  group" is one which (i) has been in existence  for more than
six  months,  (ii) has a purpose  other than  acquiring  Fund  shares at a
discount,  and (iii)  satisfies  uniform  criteria  which  enable  CDI and
dealers   offering   Fund  shares  to  realize   economies   of  scale  in
distributing  such  shares.  A  qualified  group  must  have  more than 10
members,   must  be  available  to  arrange  for  group  meetings  between
representatives  of CDI or dealers  distributing  the Funds' shares,  must
agree to  include  sales and other  materials  related to each Fund in its
publications  and  mailings  to  members  at  reduced or no cost to CDI or
dealers,  and must seek to arrange  for  payroll  deduction  or other bulk
transmission  of  investments  to the  Funds.  Members  of a group are not
eligible for a Letter of Intent.

   
Other Circumstances
There is no sales charge on shares of any fund (portfolio or series) of
the Calvert Group of Funds sold to (i) current and retired members of
the Board of Trustees/Directors of the Calvert Group of Funds, (and the
Advisory Council of the Calvert Social Investment Fund); (ii) directors,
officers and employees of the Advisor, Distributor, and their affiliated
companies; (iii) directors, officers and registered representatives of
brokers distributing the Fund's shares; and immediate family members of
persons listed in (i), (ii), and (iii), above; (iv) dealers, brokers, or
registered investment advisors that have entered into an agreement with
CDI providing specifically for the use of shares of the Fund (Portfolio
or Series) in particular investment programs or products (where such
program or product already has a fee charged therein) made available to
the clients of such dealer, broker, or registered investment advisor;
(v) trust departments of banks or savings institutions for trust clients
of such bank or savings institution; and (vi) purchases placed through a
broker maintaining an omnibus account with the Fund (Portfolio or
Series) and the purchases are made by (a) investment advisors or
financial planners placing trades for their own accounts (or the
accounts of their clients) and who charge a management, consulting, or
other fee for their services; or (b) clients of such investment advisors
or financial planners who place trades for their own accounts if such
accounts are linked to the master account of such investment advisor or
financial planner on the books and records of the broker or agent; or
(c) retirement and deferred compensation plans and trusts, including,
but not limited to, those defined in Section 401(a) or Section 403(b) of the 
I.R.C., and "rabbi trusts."
    

Dividends and Capital Gain Distributions from other Calvert Group Funds
You may prearrange to have your  dividends and capital gain  distributions
from  another  Calvert  Group  Fund  automatically   invested  in  another
account with no additional sales charge.

   
Purchases made at net asset value ("NAV")
Except for money market funds, if you make a purchase at NAV, you may
exchange that amount to another fund at no additional sales charge.
    

Reinstatement Privilege
If you redeem  Fund  shares and then  within 30 days decide to reinvest in
the same Fund,  you may do so at the net asset value next  computed  after
the reinvestment  order is received,  without a sales charge.  You may use
the  reinstatement  privilege  only once.  The Funds  reserve the right to
modify or eliminate this privilege.

         This  Statement of  Additional  Information  is not a prospectus.
Investors   should  read  the  Statement  of  Additional   Information  in
conjunction with the Series'  Prospectus,  dated April 30, 1996, which may
be obtained  free of charge by writing the Series at the above  address or
calling the Fund at the telephone numbers listed above.
    

==========================================================================
                           INVESTMENT OBJECTIVE
==========================================================================

   
     Approximately February 23, 1996, a proxy statement was mailed to Calvert 
California Municipal Intermediate Fund ("CCMIF" or the "Series") shareholders.
Shareholders were asked to approve certain changes in investment restrictions,
including the ability to purchase futures and options and non-investment grade
bonds.  The shareholder meeting scheduled for April 18, 1996 was adjourned, but
shareholder  approval of all items was expected on or about April 30, 1996.
    

         Calvert  California  Municipal  Intermediate Fund ("CCMIF" or the
"Series") is designed to provide  individual and  institutional  investors
with  the  highest  level of  interest  income  exempt  from  federal  and
California   income  taxes  as  is  consistent  with  prudent   investment
management,   preservation  of  capital,  and  the  quality  and  maturity
characteristics  of the Series.  There is, of course,  no  assurance  that
the Series will be successful in meeting its investment  objective;  there
are inherent risks in the ownership of any investment.
         Dividends  paid by CCMIF will  fluctuate  with  income  earned on
investments.  In addition,  the dividends and  distributions  paid and the
value  of each  share  will  vary by  class of  shares;  the  value of its
shares  will  fluctuate  to reflect  changes  in the  market  value of the
Series'   investments.   The  Series   will   attempt,   through   careful
management,  to reduce  these  risks and  enhance  the  opportunities  for
higher income and greater price stability.

==========================================================================
                           INVESTMENT POLICIES
==========================================================================

         CCMIF  invests   primarily  in  a  nondiversified   portfolio  of
municipal  obligations,  including  some with interest that may be subject
to  alternative   minimum  tax.  Fixed  rate  investments   normally  have
remaining  maturities of 12 years or less;  variable rate  investments may
have longer maturities.  A complete  explanation of municipal  obligations
and municipal bond and note ratings appears in the Appendix.
         Under normal  market  conditions,  CCMIF will invest at least 65%
of its  total  assets  in  municipal  obligations  with  interest  that is
exempt from federal and California  income tax,  including those issued by
or on behalf of the State of  California  and its  political  subdivisions
("California  Municipal  Obligations").  CCMIF will also attempt to invest
its  remaining  assets  in  these  obligations,   but  may  invest  it  in
municipal  obligations  of other states,  territories  and  possessions of
the  United  States,  the  District  of  Columbia,  and  their  respective
authorities,  agencies,   instrumentalities  and  political  subdivisions.
Dividends  you  receive  from  CCMIF that are  derived  from  interest  on
tax-exempt  obligations of other governmental  issuers will be exempt from
federal income tax, but will be subject to California state income taxes.

Variable Rate Demand Notes
         The Board of  Directors  of Calvert  Municipal  Fund,  Inc.  (the
"Fund"),  of  which  CCMIF  is  a  series,  has  approved  investments  in
floating and variable  rate demand  notes upon the  following  conditions:
the Fund has right of  demand,  upon  notice  not to exceed  thirty  days,
against  the issuer to receive  payment;  the issuer  will be able to make
payment  upon such  demand,  either from its own  resources  or through an
unqualified  commitment  from a  third  party;  and the  rate of  interest
payable is  calculated  to ensure that the market value of such notes will
approximate par value on the adjustment  dates. The remaining  maturity of
such demand  notes is deemed the period  remaining  until such time as the
Fund has the right to dispose of the notes at a price  which  approximates
par and market value.  Notes with a right of demand  exceeding  seven days
are considered illiquid and are subject to purchase restrictions.

Municipal Leases
         CCMIF may invest in municipal leases,  or structured  instruments
where the underlying  security is a municipal  lease. A municipal lease is
an obligation of a government or  governmental  authority,  not subject to
voter   approval,   used  to  finance   capital   projects  or   equipment
acquisitions  and payable  through  periodic  rental  payments.  CCMIF may
purchase  unrated  leases.  The Fund's  Advisor,  under the supervision of
the  Board of  Trustees/Directors,  is  responsible  for  determining  the
credit  quality  of  such  leases  on  an  ongoing  basis,   including  an
assessment  of the  likelihood  that  the  lease  will  not  be  canceled.
Certain  municipal  leases  may be  considered  illiquid  and  subject  to
CCMIF's  limit on  illiquid  securities.  The Board of  Trustees/Directors
has directed the Advisor to treat a municipal  lease as a liquid  security
if it satisfies  the  following  conditions:  (A) such  treatment  must be
consistent with CCMIF's  investment  restrictions;  (B) the Advisor should
be able to  conclude  that the  obligation  will  maintain  its  liquidity
throughout the time it is held by CCMIF,  based on the following  factors:
(1) whether the lease may be terminated  by the lessee;  (2) the potential
recovery,  if any, from a sale of the leased property upon  termination of
the lease;  (3) the lessee's  general  credit  strength  (e.g.,  its debt,
administrative,  economic and financial  characteristics  and  prospects);
(4)  the  likelihood  that  the  lessee  will  discontinue   appropriating
funding for the leased  property  because the property is no longer deemed
essential  to  its  operations  (e.g.,  the  potential  for an  "event  of
nonappropriation"),  and (5) any  credit  enhancement  or  legal  recourse
provided upon an event of  nonappropriation  or other  termination  of the
lease;  (C) the Advisor  should  determine  whether the  obligation can be
disposed  of within  seven  days in the  ordinary  course of  business  at
approximately  the  amount at which  CCMIF has valued it for  purposes  of
calculating  CCMIF's net asset value,  taking into  account the  following
factors:  (1) the  frequency of trades and quotes;  (2) the  volatility of
quotations  and  trade  prices;  (3) the  number  of  dealers  willing  to
purchase  or sell the  security  and the number of  potential  purchasers;
(4) dealer  undertakings to make a market in the security;  (5) the nature
of the security and the nature of the marketplace  trades (e.g.,  the time
needed to dispose of the security,  the method of soliciting  offers,  and
the  mechanics  of the  transfer);  (6) the rating of the security and the
financial  condition  and  prospects of the issuer;  and (7) other factors
relevant  to  CCMIF's  ability to  dispose  of the  security;  and (D) the
Advisor  should have  reasonable  expectations  that the  municipal  lease
obligation   will   maintain  its  liquidity   throughout   the  time  the
instrument is held by CCMIF.

Temporary Investments
         Short-term   money   market   type   investments    consist   of:
obligations of the U.S.  Government,  its agencies and  instrumentalities;
certificates  of deposit of banks with  assets of one  billion  dollars or
more;  commercial  paper or other  corporate  notes  of  investment  grade
quality;   and  any  of  such  items  subject  to  short-term   repurchase
agreements.

When-Issued Purchases
         Securities  purchased on a when-issued  basis and the  securities
held in CCMIF's  portfolio  are  subject to changes in market  value based
on the  public's  perception  of the  creditworthiness  of the  issuer and
changes in the level of interest  rates  (which will  generally  result in
both  changing  in  value  in  the  same  way,  i.e.,  both   experiencing
appreciation  when interest rates decline and  depreciation  when interest
rates rise).  Therefore,  if in order to achieve higher  interest  income,
CCMIF remains  substantially  fully  invested at the same time that it has
purchased  securities  on a  when-issued  basis,  there  will be a greater
possibility  that  the  market  value  of  its  assets  may  vary.  No new
when-issued  commitments  will be made if more than 50% of the Series' net
assets would become so committed.
         When the  time  comes to pay for  when-issued  securities,  CCMIF
will  meet  its  obligations  from  then  available  cash  flow,  sale  of
securities or,  although it would not normally  expect to do so, from sale
of the when-issued  securities  themselves  (which may have a market value
greater or less than the Series' payment  obligation).  Sale of securities
to meet  such  obligations  carries  with it a greater  potential  for the
realization  of capital  losses  and  capital  gains  which are not exempt
from federal income tax.

   
Transactions in Futures Contracts (effective upon shareholder approval)
         CCMIF may engage in the  purchase  and sale of futures  contracts
on an  index  of  municipal  bonds  or on  U.S.  Treasury  securities,  or
options on such futures contracts,  for hedging and substitution  purposes
only.  CCMIF may sell such futures  contracts in anticipation of a decline
in the cost of  municipal  bonds it holds  or may  purchase  such  futures
contracts in  anticipation  of an increase in the value of municipal bonds
CCMIF  intends to acquire.  CCMIF also is  authorized to purchase and sell
other financial  futures  contracts which in the opinion of the Investment
Advisor  provide  an  appropriate   hedge  for  some  or  all  of  CCMIF's
securities.
         Because of low initial  margin  deposits made upon the opening of
a futures position,  futures  transactions  involve substantial  leverage.
As a  result,  relatively  small  movements  in the  price of the  futures
contract can result in  substantial  unrealized  gains or losses.  Because
CCMIF  will  engage  in  the  purchase  and  sale  of  financial   futures
contracts  solely for  hedging and  substitution  purposes,  however,  any
losses  incurred  in  connection  therewith  should,  if the  strategy  is
successful,  be  offset in whole or in part by  increases  in the value of
securities  held by CCMIF or  decreases in the price of  securities  CCMIF
intends to acquire.
         Municipal  bond  index  futures  contracts  commenced  trading in
June 1985,  and it is  possible  that  trading in such  futures  contracts
will be less liquid than that in other futures  contracts.  The trading of
futures  contracts  and  options  thereon is  subject  to  certain  market
risks,  such as trading  halts,  suspensions,  exchange or clearing  house
equipment  failures,  government  intervention  or  other  disruptions  of
normal  trading  activity,  which  could at  times  make it  difficult  or
impossible to liquidate existing positions.
         The liquidity of a secondary  market in futures  contracts may be
further   adversely   affected  by  "daily   price   fluctuation   limits"
established  by contract  markets,  which limit the amount of  fluctuation
in the  price of a futures  contract  or  option  thereon  during a single
trading  day.  Once the daily limit has been reached in the  contract,  no
trades may be entered  into at a price beyond the limit,  thus  preventing
the  liquidation of open positions.  Prices of existing  contracts have in
the past moved the daily limit on a number of  consecutive  trading  days.
CCMIF will enter into a futures  position  only if, in the judgment of the
Investment  Advisor,  there  appears to be an  actively  traded  secondary
market for such futures contracts.
         The  successful  use of  transactions  in futures  contracts  and
options  thereon  depends  on the  ability  of the  Investment  Advisor to
correctly  forecast the direction  and extent of price  movements of these
instruments,  as well as price  movements of the securities  held by CCMIF
within a given  time  frame.  To the extent  these  prices  remain  stable
during  the  period  in which a  futures  or  option  contract  is held by
CCMIF,  or move in a  direction  opposite to that  anticipated,  CCMIF may
realize  a  loss  on  the  hedging  transaction  which  is  not  fully  or
partially offset by an increase in the value of CCMIF's  securities.  As a
result,  CCMIF's  total  return for such period may be less than if it had
not engaged in the hedging transaction.


Description of Financial Futures Contracts (effective upon shareholder 
approval)
    

         Futures  Contracts.  A futures contract obligates the seller of a
contract to deliver and the  purchaser  of a contract to take  delivery of
the type of  financial  instrument  called for in the contract or, in some
instances,  to make a cash  settlement,  at a specified  future time for a
specified  price.  Although  the  terms  of a  contract  call  for  actual
delivery or acceptance of securities,  or for a cash  settlement,  in most
cases the  contracts  are closed out before the delivery  date without the
delivery  or  acceptance  taking  place.  CCMIF  intends  to close out any
futures contracts prior to the delivery date of such contracts.
         CCMIF may sell  futures  contracts in  anticipation  of a decline
in the value of its  investments in municipal  bonds.  The loss associated
with any such  decline  could be reduced  without  employing  futures as a
hedge  by  selling  long-term   securities  and  either   reinvesting  the
proceeds in securities  with shorter  maturities  or by holding  assets in
cash. This strategy,  however,  entails increased transaction costs in the
form of  brokerage  commissions  and  dealer  spreads  and will  typically
reduce   CCMIF's   average  yields  as  a  result  of  the  shortening  of
maturities.
         The  purchase  or sale of a  futures  contract  differs  from the
purchase  or sale of a  security,  in that no price or  premium is paid or
received.  Instead, an amount of cash or securities  acceptable to CCMIF's
futures  commission  merchant  and the  relevant  contract  market,  which
varies but is generally about 5% or less of the contract  amount,  must be
deposited with the broker.  This amount is known as "initial  margin," and
represents a "good faith"  deposit  assuring the  performance  of both the
purchaser and the seller under the futures contract.  Subsequent  payments
to and from the broker,  known as  "variation  margin," are required to be
made on a daily  basis as the price of the  futures  contract  fluctuates,
making the long or short  positions in the futures  contract  more or less
valuable,  a  process  known  as  "marking  to the  market."  Prior to the
settlement  date of the futures  contract,  the position may be closed out
by taking an  opposite  position  which  will  operate  to  terminate  the
position in the  futures  contract.  A final  determination  of  variation
margin  is  then  made,  additional  cash  is  required  to be  paid to or
released  by the broker,  and the  purchaser  realizes a loss or gain.  In
addition,  a  commission  is paid  on each  completed  purchase  and  sale
transaction.
         The sale of financial futures  contracts  provides an alternative
means of hedging  CCMIF against  declines in the value of its  investments
in  municipal  bonds.  As  such  values  decline,  the  value  of  CCMIF's
position in the futures  contracts will tend to increase,  thus offsetting
all or a  portion  of the  depreciation  in the  market  value of  CCMIF's
fixed income  investments  which are being hedged.  While CCMIF will incur
commission  expenses in  establishing  and closing out futures  positions,
commissions  on  futures  transactions  may be  significantly  lower  than
transaction  costs  incurred  in the  purchase  and sale of  fixed  income
securities.   In   addition,   the  ability  of  CCMIF  to  trade  in  the
standardized  contracts  available in the futures  market may offer a more
effective  hedging  strategy than a program to reduce the average maturing
of  portfolio  securities,  due  to  the  unique  and  varied  credit  and
technical  characteristics of the municipal debt instruments  available to
CCMIF.  Employing  futures  as a hedge may also  permit  CCMIF to assume a
hedging  posture  without  reducing the yield on its  investments,  beyond
any amounts required to engage in futures trading.
         CCMIF may engage in the  purchase  and sale of futures  contracts
on an index of municipal  securities.  These  instruments  provide for the
purchase  or sale of a  hypothetical  portfolio  of  municipal  bonds at a
fixed  price  in a  stated  delivery  month.  Unlike  most  other  futures
contracts,  however,  a municipal  bond index  futures  contract  does not
require  actual  delivery of securities  but results in a cash  settlement
based  upon the  difference  in value of the  index  between  the time the
contract was entered into and the time it is liquidated.
         The  municipal  bond  index  underlying  the  futures   contracts
traded  by  the  Portfolio  is  The  Bond  Buyer   Municipal  Bond  Index,
developed by The Bond Buyer and the Chicago  Board of Trade  ("CBT"),  the
contract  market on which the futures  contracts are traded.  As currently
structured,  the  index  is  comprised  of 40  tax-exempt  term  municipal
revenue  and general  obligation  bonds.  Each bond  included in the index
must be rated  either A- or higher by  Standard & Poor's or A or higher by
Moody's Investors  Service and must have a remaining  maturity of 19 years
or  more.   Twice  a  month  new   issues   satisfying   the   eligibility
requirements  are added to,  and an equal  number  of old  issues  will be
deleted  from,  the  index.  The  value  of the  index is  computed  daily
according  to a formula  based  upon the price of each bond in the  index,
as evaluated by four dealer-to-dealers brokers.
         CCMIF  may also  purchase  and  sell  futures  contracts  on U.S.
Treasury  bills,  notes  and  bonds  for the  same  types of  hedging  and
substitution  purposes.  Such  futures  contracts  provide for delivery of
the  underlying  security  at a specified  future time for a fixed  price,
and the  value of the  futures  contract  therefore  generally  fluctuates
with movements in interest rates.
         The municipal bond index futures  contract,  futures contracts on
U.S.  Treasury  securities  and  options  on such  futures  contracts  are
traded  on the CBT,  which,  like  other  contract  markets,  assures  the
performance  of the parties to each  futures  contract  through a clearing
corporation,   a   nonprofit   organization   managed   by  the   exchange
membership,  which is also  responsible  for handling daily  accounting of
deposits or withdrawals of margin.
         CCMIF may also  purchase  financial  futures  contracts  when not
fully invested in municipal  bonds,  in anticipation of an increase in the
cost of  securities  CCMIF  intends to purchase.  As such  securities  are
purchased,  an equivalent  amount of futures contracts will be closed out.
In a  substantial  majority  of these  transactions,  CCMIF will  purchase
municipal  bonds  upon  termination  of  the  futures  contracts.  Due  to
changing  market  conditions  and  interest  rate  forecasts,  however,  a
futures  position may be terminated  without a  corresponding  purchase of
securities.  Nevertheless,  all  purchases  of futures  contracts by CCMIF
will be subject to certain restrictions, described below.
         Options on  Futures  Contracts.  An option on a futures  contract
provides the purchaser with the right,  but not the  obligation,  to enter
into  a long  position  in  the  underlying  futures  contract  (that  is,
purchase  the  futures  contract),  in the case of a "call"  option,  or a
short  position  (sell  the  futures  contract),  in the  case  of a "put"
option,  for a fixed price up to a stated  expiration  date. The option is
purchased  for  a  non-refundable   fee,  known  as  the  "premium."  Upon
exercise of the option,  the contract  market  clearing house assigns each
party  to the  option  an  opposite  position  in the  underlying  futures
contract.  In the event of  exercise,  therefore,  the parties are subject
to all of the risks of futures  trading,  such as  payment of initial  and
variation margin.  In addition,  the seller, or "writer," of the option is
subject  to  margin  requirements  on  the  option  position.  Options  on
futures  contracts  are  traded  on  the  same  contract  markets  as  the
underlying futures contracts.
         CCMIF may  purchase  options  on futures  contracts  for the same
types of purposes  described above in connection  with futures  contracts.
For example,  in order to protect  against an  anticipated  decline in the
value of  securities  it  holds,  CCMIF  could  purchase  put  options  on
futures  contracts,  instead of selling the underlying  futures contracts.
Conversely,   in  order  to  protect   against  the  adverse   effects  of
anticipated  increases in the costs of  securities  to be acquired,  CCMIF
could  purchase call options on futures  contracts,  instead of purchasing
the underlying  futures  contracts.  CCMIF  generally will sell options on
futures contracts only to close out an existing position.
         CCMIF  will  not  engage  in  transactions  in  such  instruments
unless  and  until  the   Investment   Advisor   determines   that  market
conditions  and the  circumstances  of CCMIF warrant such trading.  To the
extent  CCMIF  engages in the  purchase  and sale of futures  contracts or
options  thereon,  it will do so only at a level  which is  reflective  of
the  Investment  Advisor's  view  of  the  hedging  needs  of  CCMIF,  the
liquidity  of  the  market  for  futures  contracts  and  the  anticipated
correlation  between  movements  in the  value of the  futures  or  option
contract and the value of securities held by the Portfolio.
         Restrictions  on the Use of  Futures  Contracts  and  Options  on
Futures  Contracts.  Under  regulations of the Commodity  Futures  Trading
Commission  ("CFTC"),  the futures  trading  activities  described  herein
will not  result  in CCMIF  being  deemed  to be a  "commodity  pool,"  as
defined   under  such   regulations,   provided   that   certain   trading
restrictions  are  adhered to. In  particular,  CFTC  regulations  require
that all futures and option  positions  entered  into by CCMIF  qualify as
bona fide hedge  transactions,  as defined under CFTC regulations,  or, in
the case of long  positions,  that the value of such  positions not exceed
an amount of  segregated  funds  determined  by  reference to certain cash
and securities  positions  maintained by CCMIF and accrued profits on such
positions.  In addition,  as a matter of operating  policy,  CCMIF may not
purchase or sell a futures  contract or an option thereon if,  immediately
thereafter,  the sum of the amount of initial  margin  deposits on CCMIF's
existing  futures  positions  and premiums on such options would exceed 5%
of its net assets.
         When CCMIF  purchases  a futures  contract,  it will  maintain an
amount  of cash,  cash  equivalents  (for  example,  commercial  paper and
daily  tender  adjustable  notes) or  short-term  high-grade  fixed income
securities  in a segregated  account with CCMIF's  custodian,  so that the
amount so  segregated  plus the amount of  initial  and  variation  margin
held in the account of its broker  equals the market  value of the futures
contract, thereby ensuring that the use of such futures is unleveraged.
         Risk  Factors  in   Transactions   in  Futures   Contracts.   The
particular  municipal bonds  comprising the index underlying the municipal
bond index  futures  contract  may vary from the bonds  held by CCMIF.  In
addition,  the securities  underlying  futures  contracts on U.S. Treasury
securities  will  not be the  same  as  securities  held  by  CCMIF.  As a
result,  CCMIF's  ability  effectively  to hedge all or a  portion  of the
value of its  municipal  bonds through the use of futures  contracts  will
depend  in part on the  degree  to  which  price  movements  in the  index
underlying  the  municipal  bond  index  futures  contract,  or  the  U.S.
Treasury  securities  underlying other futures contracts trade,  correlate
with price movements of the municipal bonds held by CCMIF.
         For example,  where prices of  securities in CCMIF do not move in
the same  direction or to the same extent as the values of the  securities
or index  underlying  a futures  contract,  the  trading  of such  futures
contracts may not  effectively  hedge CCMIF's  investments  and may result
in trading  losses.  The correlation may be affected by disparities in the
average  maturity,  ratings,  geographical  mix or  structure  of  CCMIF's
investments  as  compared  to those  comprising  the  index,  and  general
economic or  political  factors.  In  addition,  the  correlation  between
movements in the value of the index  underlying a futures  contract may be
subject to change  over  time,  as  additions  to and  deletions  from the
index  alter  its  structure.  In the case of  futures  contracts  on U.S.
Treasury  securities and options thereon,  the anticipated  correlation of
price  movements  between  the U.S.  Treasury  securities  underlying  the
futures  or options  and  municipal  bonds may be  adversely  affected  by
economic,  political,  legislative  or  other  developments  that  have  a
disparate  impact on the respective  markets for such  securities.  In the
event that the Investment  Advisor  determines to enter into  transactions
in  financial  futures  contracts  other  than the  municipal  bond  index
futures  contract  or futures  on U.S.  Treasury  securities,  the risk of
imperfect  correlation  between  movements  in the prices of such  futures
contracts and the prices of municipal bonds held by CCMIF may be greater.
         The  trading of futures  contracts  on an index also  entails the
risk of  imperfect  correlation  between  movements  in the  price  of the
futures  contract and the value of the underlying  index.  The anticipated
spread  between  the prices may be  distorted  due to  differences  in the
nature of the  markets,  such as margin  requirements,  liquidity  and the
participation  of  speculators  in  the  futures  markets.   The  risk  of
imperfect  correlation,  however,  generally  diminishes  as the  delivery
month specified in the futures contract approaches.
         Prior  to   exercise  or   expiration,   a  position  in  futures
contracts or options  thereon may be  terminated  only by entering  into a
closing  purchase or sale  transaction.  This requires a secondary  market
on the  relevant  contract  market.  CCMIF  will  enter  into a futures or
option  position  only if there  appears to be a liquid  secondary  market
therefor,   although  there  can  be  no  assurance  that  such  a  liquid
secondary  market will exist for any  particular  contract at any specific
time.  Thus,  it may not be possible  to close out a position  once it has
been  established.  Under such  circumstances,  CCMIF could be required to
make  continuing  daily cash payments of variation  margin in the event of
adverse price  movements.  In such  situation,  if CCMIF has  insufficient
cash,  it may be  required  to sell  portfolio  securities  to meet  daily
variation  margin  requirements  at a time when it may be  disadvantageous
to do so. In  addition,  CCMIF may be required to perform  under the terms
of the futures or option  contracts it holds.  The  inability to close out
futures  or  options  positions  also  could  have an  adverse  impact  on
CCMIF's ability effectively to hedge its portfolio.
         When CCMIF  purchases an option on a futures  contract,  its risk
is limited to the amount of the premium,  plus related  transaction costs,
although this entire  amount may be lost. In addition,  in order to profit
from the  purchase  of an  option  on a  futures  contract,  CCMIF  may be
required to  exercise  the option and  liquidate  the  underlying  futures
contract,  subject to the availability of a liquid secondary  market.  The
trading  of  options  on  futures  contracts  also  entails  the risk that
changes  in the  value  of the  underlying  futures  contract  will not be
fully  reflected  in the  value  of  the  option,  although  the  risk  of
imperfect  correlation  generally  tends to diminish as the maturity  date
of the futures contract or expiration date of the option approaches.
         "Trading  Limits"  or  "Position  Limits"  may also be imposed on
the  maximum  number of  contracts  which any  person  may hold at a given
time. A contract  market may order the  liquidation of positions  found to
be in  violation  of these  limits and it may impose  other  sanctions  or
restrictions.  The  Investment  Advisor  does  not  believe  that  trading
limits  will have any  adverse  impact on the  strategies  for hedging the
CCMIF's investments.
         Further,  the  trading  of  futures  contracts  is subject to the
risk  of the  insolvency  of a  brokerage  firm or  clearing  corporation,
which  could  make  it  difficult  or  impossible  to  liquidate  existing
positions or to recover excess variation margin payments.
         In addition to the risks of imperfect  correlation  and lack of a
liquid  secondary  market for such  instruments,  transactions  in futures
contracts  involve  risks  related to  leveraging  and the  potential  for
incorrect   forecasts  of  the  direction  and  extent  of  interest  rate
movements within a given time frame.


   
Credit Quality
         As an  operating  policy,  (effective upon shareholder approval)
the Fund may not invest  more than 35% of its net assets in  non-investment 
grade  obligations.  As has been the industry  practice,  this  determination 
of credit quality is made at the time the Fund  acquires  the  obligation  
However,  because it is possible that  subsequent  downgrades  could occur,
if an  obligation  held by the Fund is later  downgraded,  CCMIF's  Advisor, 
under  the  supervision  of CCMIF's  Board  of  Directors,  will  consider 
whether  it is in the best interest   of  CCMIF's   shareholders   to  hold  
or  to  dispose  of  the obligation.  Among the criteria  that may be 
considered by the Advisor and the Board are the probability  that the  
obligations  will be able to make scheduled  interest and  principal  payments
in the future,  the extent to which any  devaluation  of the  obligation  has 
already been  reflected in CCMIF's  net  asset  value,   and  the  total  
percentage,   if  any,  of obligations currently rated below investment grade 
held by the Fund.
         Non-investment   grade   securities   have   moderate   to   poor
protection  of  principal  and  interest  payments  and  have  speculative
characteristics.  They involve  greater risk of default or price  declines
due to  changes in the  issuer's  creditworthiness  than  investment-grade
debt  securities.  Because the market for  lower-rated  securities  may be
thinner  and less active than for  higher-rated  securities,  there may be
market price  volatility  for these  securities  and limited  liquidity in
the  resale  market.  Market  prices  for  these  securities  may  decline
significantly  in  periods  of  general  economic   difficulty  or  rising
interest rates.

==========================================================================


Fundamental Investment Restrictions
         The   foregoing   investment   objective  and  policies  and  the
following  investment  restrictions  and  fundamental  policies may not be
changed  without  the  consent of the  holders  of a  majority  of CCMIF's
outstanding  shares.  Shares have equal rights as to voting. A majority of
the  shares  means the lesser of (i) 67% of the  shares  represented  at a
meeting at which more than 50% of the  outstanding  shares are represented
or (ii) more than 50% of the outstanding shares. CCMIF may not:
         1)    Purchase   common   stocks,    preferred   stocks,
              warrants, or other equity securities;
         2)    Issue senior securities,  borrow money, or pledge,
              mortgage,  or hypothecate its assets, except as may
              be  necessary to secure  borrowings  from banks for
              temporary or emergency  (not  leveraging)  purposes
              and then in an amount not  greater  than 10% of the
              value of the  Series'  total  assets at the time of
              the borrowing.  Investment  securities  will not be
              purchased while any borrowings are outstanding;
         3)    Underwrite   the   securities  of  other  issuers,
              except  to  the  extent   that  the   purchase   of
              municipal   obligations  in  accordance   with  the
              Series' investment  objective and policies,  either
              directly  from the issuer,  or from an  underwriter
              for an issuer, may be deemed an underwriting;
         4)    Purchase   or  sell  real   estate,   real  estate
              investment  trust   securities,   or  oil  and  gas
              interests,  but this shall not  prevent  CCMIF from
              investing in municipal  obligations secured by real
              estate or interests therein;
         5)    Purchase  or  retain  securities  of an  issuer if
              those  directors  of the  Fund,  each of whom  owns
              more than 1/2 of 1% of the  outstanding  securities
              of such  issuer,  together own more than 5% of such
              outstanding securities;

   
         6)    Purchase or sell physical  commodities except that
              it may enter into  futures  contracts  and  options
              thereon (effective upon shareholder approval);
    

         7)    Invest in companies  for the purpose of exercising
              control;   or   invest  in   securities   of  other
              investment   companies,   except  as  they  may  be
              acquired  as part  of a  merger,  consolidation  or
              acquisition  of  assets,  or in  connection  with a
              trustee's/director's  deferred  compensation  plan,
              as long as  there  is no  duplication  of  advisory
              fees;
         8)    Invest   25%  or  more  of  its   assets   in  the
              securities  of any one  issuer.  CCMIF  may  invest
              more than 25% of its assets in  obligations  issued
              or guaranteed by the U.S. Government,  its agencies
              or  instrumentalities  but will invest in more than
              20%  of  such   obligations  only  during  abnormal
              market    conditions.    For   purposes   of   this
              limitation,  the  entity  which  has  the  ultimate
              responsibility  for the  payment of  principal  and
              interest on a particular  security  will be treated
              as its issuer;
         9)    Invest   25%  or  more  of  its   assets   in  any
              particular   industry  or  industries.   CCMIF  may
              invest  more than 25% of its assets in  obligations
              issued or  guaranteed by the U.S.  Government,  its
              agencies  or  instrumentalities  but will invest in
              more  than  20% of  such  obligations  only  during
              abnormal market conditions.  Industrial development
              bonds,  where the payment of principal and interest
              is the  responsibility of companies within the same
              industry, are grouped together as an "industry";
         10)   (10)Make  loans to  others,  except in  accordance
              with the Series' investment  objective and policies
              or  pursuant  to   contracts   providing   for  the
              compensation  of service  providers by compensating
              balances.


Nonfundamental Investment Restrictions

   
         The  Series  has   adopted   the   following   operating   (i.e.,
nonfundamental)   investment   policies  and  restrictions  which  may  be
changed by the Board of  Directors  without  shareholder  approval.  CCMIF
may not:
         1)    Purchase  illiquid  securities if more than 15% of
              the value of its net assets  would be  invested  in
              such securities;
         2)    Invest  more  than 5% of the  value  of its  total
              assets  in   securities   where  the   payment   of
              principal and interest is the  responsibility  of a
              company or  companies  with less than three  years'
              operating history;
         3)    Purchase  or sell a futures  contract or an option
              thereon if immediately  thereafter,  the sum of the
              amount of initial  margin  deposits  on futures and
              premiums  on  such  options   would  exceed  5%  of
              CCMIF's net assets (effective upon shareholder approval);
         4)    Invest in puts or calls on a  security,  including
              straddles,  spreads,  or  any  combination,  if the
              value of that option premium,  when aggregated with
              the  premiums  on all other  options on  securities
              held  by the  Fund,  exceeds  5% of  CCMIF's  total
              assets (effective upon shareholder approval).
         5)   Effect short sales of securities.  For purposes of
              this    restriction,    transactions   in   futures
              contracts  and options are not deemed to constitute
              selling securities short (effective upon shareholder approval).
         6)   Purchase securities on margin,  except that it may
              make margin  deposits in  connection  with  futures
              contacts or options on futures (effective upon shareholder 
              approval).
    

==========================================================================
                   PURCHASES AND REDEMPTIONS OF SHARES
==========================================================================

         Share  certificates  will be issued at no charge if  requested in
writing by the investor.  No  certificates  will be issued for  fractional
shares (see Prospectus,  "How to Sell Your Shares").  To change redemption
instructions  already  given,  shareholders  must send a written notice to
Calvert  Group,  c/o NFDS,  6th Floor,  1004  Baltimore,  Kansas City,  MO
64105,  with a voided copy of a check for the bank wiring  instructions to
be added.  If a voided  check does not  accompany  the  request,  then the
request must be signature  guaranteed  by a commercial  bank,  savings and
loan association,  trust company,  member firm of any national  securities
exchange,   or  certain  credit  unions.   Further  documentation  may  be
required from corporations, fiduciaries, and institutional investors.
         The right of  redemption  may be suspended or the date of payment
postponed  for any  period  during  which the New York Stock  Exchange  is
closed (other than customary weekend and holiday  closings),  when trading
on the New York Stock Exchange is restricted,  or an emergency  exists, as
determined  by  the  SEC,  or  if  the   Commission  has  ordered  such  a
suspension for the  protection of  shareholders.  Redemption  proceeds are
normally  mailed or wired the next business day after a proper  redemption
request has been  received,  unless  redemptions  have been  suspended  or
postponed as described above.
         Redemption  proceeds are normally  paid in cash.  However,  CCMIF
has the right to redeem  shares in assets  other than cash for  redemption
amounts exceeding,  in any 90-day period,  $250,000 or 1% of the net asset
value of CCMIF, whichever is less.

Reduced Sales Charges (Class A)
         CCMIF  imposes  reduced  sales  charges  for  Class A  shares  in
certain  situations in which the Principal  Underwriter  (which offers the
Series'  shares  continuously  and on a  "best  efforts"  basis)  and  the
dealers selling CCMIF shares may expect to realize  significant  economies
of  scale  with  respect  to such  sales.  Generally,  sales  costs do not
increase  in  proportion  to the  dollar  amount of the shares  sold;  the
per-dollar  transaction  cost for a sale to an  investor  of shares  worth
$5,000 is  generally  much higher than the  per-dollar  cost for a sale of
shares worth  $1,000,000.  Thus, the applicable sales charge declines as a
percentage  of the  dollar  amount of  shares  sold as the  dollar  amount
increases.
         When a  shareholder  agrees to make  purchases  of shares  over a
period of time totaling a certain  dollar  amount  pursuant to a Letter of
Intent,  the  Underwriter  and  selling  dealers can expect to realize the
economies  of  scale  applicable  to that  stated  goal  amount.  Thus the
Series   imposes  the  sales  charge   applicable   to  the  goal  amount.
Similarly,  the  Underwriter  and selling  dealers  also  experience  cost
savings  when  dealing  with  existing  CCMIF  shareholders,  enabling the
Series to afford  existing  shareholders  the Right of  Accumulation.  The
Underwriter  and selling  dealers can also expect to realize  economies of
scale when making sales to the members of certain  qualified  groups which
agree to facilitate  distribution of Series' shares to their members.  See
"Exhibit A - Reduced Sales Charges" in the Prospectus.

                       DIVIDENDS AND DISTRIBUTIONS
==========================================================================

         CCMIF  declares and pays  monthly  dividends of its net income to
shareholders  of  record as of the close of  business  on each  designated
monthly record date.  Dividends and  distributions  paid will differ among
the  classes.  Net  investment  income  consists  of the  interest  income
earned  on  investments  (adjusted  for  amortization  of  original  issue
discounts  or  premiums  or market  premiums),  less  estimated  expenses.
Capital  gains,  if  any,  are  normally  paid  once a year  and  will  be
automatically   reinvested  at  net  asset  value  in  additional  shares.
Dividends  and  any   distributions   are   automatically   reinvested  in
additional  shares of the Fund,  unless you elect to have the dividends of
$10 or more paid in cash (by check or by Calvert  Money  Controller).  You
may  also  request  to have  your  dividends  and  distributions  from the
Series  invested  in  shares  of  any  other  Calvert  Group  Fund,  at no
additional  charge.  If you elect to have dividends  and/or  distributions
paid in cash, and the U.S.  Postal  Service  cannot deliver the check,  or
if it remains  uncashed  for six months,  it, as well as future  dividends
and distributions, will be reinvested in additional shares.

==========================================================================
                               TAX MATTERS
==========================================================================

         In 1995 the Series  did  qualify  and in 1996 the Series  intends
to qualify as a "regulated  investment  company" under Subchapter M of the
Internal  Revenue  Code as amended (the  "Code").  By so  qualifying,  the
Series  will not be subject  to federal  income  tax,  nor to the  federal
excise  tax  imposed by the Tax  Reform  Act of 1986 (the  "Act"),  to the
extent  that  it  distributes  its  net  investment  income  and  realized
capital gains.
         CCMIF's   dividends   of   net   investment   income   constitute
exempt-interest   dividends  on  which   shareholders  are  not  generally
subject  to  federal  income  tax;   however  under  the  Act,   dividends
attributable  to  interest  on  certain  private  activity  bonds  must be
included in federal  alternative  minimum  taxable  income for the purpose
of determining  liability (if any) for individuals  and for  corporations.
CCMIF's  dividends  derived from taxable interest and distributions of net
short-term  capital  gains,   whether  taken  in  cash  or  reinvested  in
additional  shares,  are taxable to shareholders as ordinary income and do
not qualify for the  dividends  received  deduction for  corporations.  If
you held  shares  for six  months  or less,  losses  must be offset by the
amount of  exempt-interest  dividends you received,  and, to the extent of
capital  gain  distributions  you  received,  the loss  amount  not offset
(disallowed) must be treated as long-term capital loss.
         A  shareholder  may also be subject to some state and local taxes
on dividends  and  distributions  from the Series.  The Series will notify
shareholders   annually   about   the  tax   status   of   dividends   and
distributions  paid by the Series and the  amount of  dividends  withheld,
if any, during the previous year.
         The Code  provides  that  interest  on  indebtedness  incurred or
continued in order to purchase or carry  shares of a regulated  investment
company which  distributes  exempt-interest  dividends  during the year is
not  deductible.  Furthermore,  entities or persons  who are  "substantial
users"  (or  persons  related  to   "substantial   users")  of  facilities
financed by private  activity  bonds  should  consult  their tax  advisors
before  purchasing shares of the Series.  "Substantial  user" is generally
defined as including a  "non-exempt  person" who  regularly  uses in trade
or  business a part of a facility  financed  from the  proceeds of private
activity bonds.
         Investors  should  note that the Code may  require  investors  to
exclude the initial  sales  charge,  if any, paid on the purchase of CCMIF
shares  from the tax basis of those  shares if the  shares  are  exchanged
for  shares of another  Calvert  Group  Fund  within 90 days of  purchase.
This  requirement  applies  only to the  extent  that the  payment  of the
original  sales  charge on the shares of the Series  causes a reduction in
the sales  charge  otherwise  payable on the shares of the  Calvert  Group
Fund  acquired in the  exchange,  and  investors  may treat sales  charges
excluded  from the basis of the original  sales as incurred to acquire the
new shares.
         The Series  may be  required  to  withhold  31% of any  long-term
capital gain dividends and 31% of each  redemption  transaction  occurring
in the Series if: (a) the  shareholder's  social  security number or other
taxpayer  identification  number  ("TIN") is not  provided or an obviously
incorrect  TIN is provided;  (b) the  shareholder  does not certify  under
penalties of perjury that the TIN  provided is the  shareholder's  correct
TIN and that the  shareholder is not subject to backup  withholding  under
section  3406(a)(1)(C)  of the Code  because of  underreporting  (however,
failure  to  provide  certification  as  to  the  application  of  section
3406(a)(1)(C)  will  result  only in backup  withholding  on capital  gain
dividends,  not on  redemptions);  or (c) the  Series is  notified  by the
Internal  Revenue  Service  that the TIN  provided by the  shareholder  is
incorrect or that there has been  underreporting  of interest or dividends
by the  shareholder.  Affected  shareholders  will receive  statements  at
least annually specifying the amount withheld.
         In  addition,  the Series is required  to report to the  Internal
Revenue  Service the  following  information  with  respect to  redemption
transactions  in  CCMIF:  (a) the  shareholder's  name,  address,  account
number and taxpayer  identification  number; (b) the total dollar value of
the redemptions; and (c) the Series' identifying CUSIP number.
         Certain  shareholders  are,  however,   exempt  from  the  backup
withholding  and  broker  reporting   requirements.   Exempt  shareholders
include: corporations;  financial institutions;  tax-exempt organizations;
individual   retirement   plans;  the  U.S.,  a  State,  the  District  of
Columbia,  a U.S.  possession,  a  foreign  government,  an  international
organization,  or any political  subdivision,  agency, or  instrumentality
of  any  of the  foregoing;  U.S.  registered  commodities  or  securities
dealers;  real estate investment trusts;  registered investment companies;
bank common trust funds;  certain  charitable  trusts; and foreign central
banks of issue.  Non-resident  aliens  also are  generally  not subject to
either  requirement  but,  along with  certain  foreign  partnerships  and
foreign  corporations,   may  instead  be  subject  to  withholding  under
section  1441 of the Code.  Shareholders  claiming  exemption  from backup
withholding  and  broker  reporting  should  call or  write  the  Fund for
further information.

==========================================================================
                           VALUATION OF SHARES
==========================================================================

         CCMIF's  assets  are  valued  utilizing  the  average  bid dealer
market   quotation  as  furnished  by  an  independent   pricing  service.
Securities  and other assets for which market  quotations  are not readily
available  are valued based on the current  market for similar  securities
or  assets,  as  determined  in good faith by  CCMIF's  Advisor  under the
supervision of the Board of Directors.
         Valuations,   market   quotations  and  market   equivalents  are
provided  the Fund by Kenny  S&P  Evaluation  Services,  a  subsidiary  of
McGraw-Hill.  The use of Kenny as a pricing  service  by the Fund has been
approved  by the  Board of  Directors.  Valuations  provided  by Kenny are
determined  without  exclusive  reliance  on quoted  prices  and take into
consideration  appropriate  factors  such as  institution-size  trading in
similar  groups of  securities,  yield,  quality,  coupon rate,  maturity,
type of issue, trading characteristics, and other market data.
         CCMIF  determines  the net  asset  value  for  each  class of its
shares every  business day at the close of the regular  session of the New
York stock  exchange  (generally,  4:00 p.m.  Eastern  time),  and at such
other  times as may be  necessary  or  appropriate.  The  Series  does not
determine  net asset value on certain  national  holidays or other days on
which the New York Stock Exchange is closed:  New Year's Day,  Presidents'
Day,   Good  Friday,   Memorial   Day,   Independence   Day,   Labor  Day,
Thanksgiving Day, and Christmas Day.

==========================================================================
                  CALCULATION OF YIELD AND TOTAL RETURN
==========================================================================

         CCMIF  may  advertise  its  "total   return."   Total  return  is
calculated  separately  for each  class.  Total  return is  historical  in
nature and is not intended to indicate  future  performance.  Total return
will be quoted for the most  recent  one-year  period,  five-year  period,
and  period  from  inception  of  CCMIF's   offering  of  shares.   Return
quotations  for  periods  in  excess  of one year  represent  the  average
annual total return for the period  included in the particular  quotation.
Total return is a computation  of CCMIF's  dividend  yield,  plus or minus
realized or unrealized  capital  appreciation or  depreciation,  less fees
and expenses.  All Class A total return  quotations  reflect the deduction
of CCMIF's  maximum  sales charge  ("return  with maximum  load"),  except
quotations  of  "return  without  maximum  load"  which do not  deduct the
sales charge.  Note: "Total Return" as quoted in the Financial  Highlights
section  of the  Series'  Prospectus  and Annual  Report to  Shareholders,
however,  per SEC  instructions,  does not reflect  deduction of the sales
charge,  and  corresponds to "return  without maximum load" as referred to
herein.   Return  without  maximum  load  should  be  considered  only  by
investors,  such as  participants  in certain  pension plans,  to whom the
sales  charge  does not apply,  or for  purposes of  comparison  only with
comparable  figures  which  also do not  reflect  sales  charges,  such as
Lipper  averages.  Total  return is computed  according  to the  following
formula:

                             P(1 + T)n = ERV

where P = a hypothetical  initial payment of $1,000;  T = total return;  n
=  number  of  years;  and  ERV  =  the  ending   redeemable  value  of  a
hypothetical  $1,000  payment made at the beginning of the 1, 5 or 10 year
periods at the end of such periods (or portions  thereof,  if applicable).
Returns for the one year period and period  from  inception  (Class A, May
29, 1992; Class C, March 1, 1994) are as follows:

   
                  Class A Shares        Class A Shares        Class C
Shares
                  With Max. Load        W/O Max. Load

One Year          8.96%                 12.07%                10.99%
From Inception    5.63%                  6.44%                 4.28%
    

         CCMIF may also  advertise  its  "yield" and  "taxable  equivalent
yield." As with total return,  both yield figures are  historical  and are
not intended to indicate future  performance.  "Yield" quotations for each
class of CCMIF refer to the aggregate  imputed  yield-to-maturity  of each
of the Series'  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
reimbursement),  divided  by  the  average  daily  number  of  outstanding
shares for that class  entitled  to receive  dividends  times the  maximum
offering  price on the last day of the  period  (so that the effect of the
sales  charge  is  included  in the  calculation),  compounded  on a "bond
equivalent," or  semi-annual,  basis.  Yield is computed  according to the
following formula:

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

where a = dividends and interest  earned  during the period;  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 maximum  offering  price per share on the
last day of the period.
         The taxable  equivalent  yield is the yield an investor  would be
required to obtain from taxable  investments to equal CCMIF's  yield,  all
or a  portion  of which may be  exempt  from  federal  income  taxes.  The
taxable  equivalent  yield for the federal and state level is computed for
each  class by  taking  the  portion  of the  yield  exempt  from  regular
federal and California  income taxes and  multiplying  the exempt yield by
a factor  based on a stated  income tax rate,  then  adding the portion of
the yield that is not exempt from regular  federal and  California  income
taxes.  The taxable  equivalent  yield for each class of the federal level
only is computed by taking the  portion of the yield  exempt from  federal
income  taxes and  multiplying  the  exempt  yield by a factor  based on a
stated  income tax rate,  then adding the portion of the yield that is not
exempt from federal  income  taxes.  The factor which is used to calculate
the tax equivalent  yield is the  reciprocal of the  difference  between 1
and  the  applicable  income  tax  rate,  which  will  be  stated  in  the
advertisement.
         For the  thirty-day  period  ended  December  31,  1995,  CCMIF's
yield  for  Class A shares  was  4.12%  and its tax  equivalent  yield was
6.43% for an  investor in the 36% federal  income tax  bracket,  and 6.85%
for an  investor in the 39.6%  federal  income tax  bracket.  For the same
period,  CCMIF's  yield for Class C shares was 3.38% and its  federal  tax
equivalent  yield was 5.28% for an investor in the 36% federal  income tax
bracket,  and  5.62%  for an  investor  in the 39.6%  federal  income  tax
bracket.

unless   otherwise  noted,  is  4550  Montgomery   Avenue,   Suite  1000N,
Bethesda, Maryland 20814.
         The Audit  Committee  of the Board of  Directors  is  composed of
Messrs.  Baird, Blatz,  Feldman,  Guffey, and Pugh. The Board's Investment
Policy  Committee is composed of Messrs.  Borts,  Diehl,  Gavian,  Rochat,
Silby, and Sorrell.
         Directors  and  officers  of the Fund as a group own less than 1%
of Calvert California Municipal Intermediate Fund's outstanding shares.
         During  fiscal 1995,  directors of the Fund not  affiliated  with
the  Fund's   Advisor  were  paid  $3,424.   Directors  of  the  Fund  not
affiliated  with the  Advisor  currently  receive an annual fee of $20,250
for  service  as a  member  of  the  Board  of  Trustees/Directors  of the
Calvert  Group of Funds  plus a fee of $750 to $1200  for each  Board  and
Committee  meeting  attended;  such fees are allocated  among the Funds on
the basis of their net assets.
         Directors of the Series not affiliated  with the Series'  Advisor
may  elect to  defer  receipt  of all or a  percentage  of their  fees and
invest  them in any  fund in the  Calvert  Family  of  Funds  through  the
Directors/Trustees  Deferred  Compensation  Plan  (shown  as  "Pension  or
Retirement  Benefits Accrued as part of Fund Expenses,"  below).  Deferral
of the fees is designed to  maintain  the parties in the same  position as
if the fees were paid on a current  basis.  Management  believes this will
have a negligible  effect on the Fund's assets,  liabilities,  net assets,
and net income per share,  and will  ensure  that there is no  duplication
of advisory fees.

==========================================================================
                            INVESTMENT ADVISOR
==========================================================================

   
         The  Fund's  Investment   Advisor  is  Calvert  Asset  Management
Company,  Inc., 4550 Montgomery Avenue,  Suite 1000N,  Bethesda,  Maryland
20814,  a subsidiary  of Calvert  Group,  Ltd.,  which is a subsidiary  of
Acacia  Mutual  Life  Insurance  Company  of  Washington,   D.C.  ("Acacia
Mutual").
         The  Advisory  Contract  between  the Fund and the  Advisor  will
remain in effect  indefinitely,  provided continuance is approved at least
annually  by the vote of the  holders  of a  majority  of the  outstanding
shares  of  the  Fund,  or by  the  directors  of the  Fund;  and  further
provided that such  continuance  is also approved  annually by the vote of
a  majority  of the  directors  of the  Fund  who are not  parties  to the
Contract  or  interested  persons  of such  parties,  cast in  person at a
meeting  called for the purpose of voting on such  approval.  The Contract
may be  terminated  without  penalty  by  either  party on 60 days'  prior
written  notice;   it  automatically   terminates  in  the  event  of  its
assignment.
         Under the  Contract,  the  Advisor  manages  the  investment  and
reinvestment  of the Fund's  assets,  subject to the direction and control
of the Fund's Board of Directors.  For its services,  the Advisor receives
an annual fee of 0.60% of the first $500  million of the  Series'  average
daily net  assets,  0.50% of the next $500  million  of such  assets,  and
0.40% of all assets over $1 billion.
         The advisory  fee is payable  monthly.  The Advisor  reserves the
right  (i) to waive  all or a part of its fee and (ii) to  compensate,  at
its expense,  broker-dealers  in  consideration  of their  promotional and
administrative  services.  The Advisor may  recapture in later  years,  to
the  extent  permitted  by law,  fees it waived  and  expenses  it paid in
prior  years.  Specifically,  the  Advisor  may  recapture  fees waived or
deferred and expenses  reimbursed  for the prior two-year  period,  but in
no event may it  recapture  fees or expenses for any period later than the
two-year period ending  December 31, 1996.  Recapture is permitted only to
the  extent  it  does  not  result  in  the  Series's  aggregate  expenses
exceeding  an  annual  expense  limit of 2.00% of its  average  daily  net
assets.  The  advisory fee incurred in any given year will be paid in full
before  any  recapture  fees are paid for a prior  year.  Recaptured  fees
will apply to the most recent suspension/reimbursement period.
         The  Advisor  provides  the  Fund  with  investment   advice  and
research,  pays the  salaries  and  fees of all  directors  and  executive
officers of the Fund who are  principals of the Advisor,  and pays certain
Fund  advertising  and  promotional  expenses.  The Fund  pays  all  other
administrative  and  operating   expenses,   including:   custodial  fees;
shareholder  servicing,  dividend  disbursing  and  transfer  agency fees;
administrative  service fees;  federal and state  securities  registration
fees;  insurance  premiums;  trade association dues;  interest,  taxes and
other business fees;  legal and audit fees; and brokerage  commissions and
other  costs   associated   with  the   purchase  and  sale  of  portfolio
securities.
         The  Advisor  has  agreed to  reimburse  CCMIF for all  expenses,
excluding brokerage,  taxes,  interest, and extraordinary items exceeding,
on a pro rata basis,  the most  restrictive  expense  limitation  in those
states which the Series'  shares are qualified for sale  (currently,  2.5%
of the Series'  first $30 million of average  net  assets,  decreasing  to
1.5% for assets  over $100  million).  During  fiscal  1993,  the  Advisor
waived  advisory fee of $162,908  and  reimbursed  the Series  $33,272 for
other  expenses.  During fiscal 1994, the Advisor  received  advisory fees
of  $194,484,  and waived  advisory  fees of  $53,268.  The  Advisor  also
reimbursed the Series $7,343 for other  expenses.  During fiscal 1995, the
Advisor received advisory fees of $233,024.
    

==========================================================================
                         ADMINISTRATIVE SERVICES
==========================================================================

      Calvert Administrative  Services Company, a wholly-owned  subsidiary
of Calvert Group,  Ltd., has been retained by the Fund to provide  certain
administrative  services  necessary to the conduct of the Series' affairs.
Such  services   include  the  preparation  of  corporate  and  regulatory
reports and filings,  portfolio  accounting,  and the daily  determination
of  net  investment  income  and  net  asset  value  per  share.   Calvert
Administrative  Services  Company  receives  an annual fee of 0.10% of the
Series'  average net assets for providing such services.  The fees paid by
the Series to Calvert  Shareholder  Services,  Inc. for fiscal years 1993,
1994, and 1995 were $27,151, $41,292, and $38,837, respectively.

==========================================================================
                          METHOD OF DISTRIBUTION
==========================================================================

   
         The  Series  has  entered   into  an   agreement   with   Calvert
Distributors,  Inc. ("CDI"),  whereby CDI, acting as principal underwriter
for the Series,  makes a continuous  offering of the Series' securities on
a  "best   efforts"   basis.   Prior  to  April  1,  1995,  the  principal
underwriter was Calvert Securities  Corporation  ("CSC").  Under the terms
of the  agreement,  CDI  bears  all its  expenses  of  providing  services
pursuant  to the  agreement,  including  payment  of any  commissions  and
service  fees.  CDI  receives  all sales  charges  imposed on the  Series'
shares and compensates  broker-dealer  firms for sales of such shares (see
"Alternative  Sales  Options"  in  the  Prospectus).  CDI is  entitled  to
receive   reimbursement   of   distribution   expenses   pursuant  to  the
Distribution  Plans  (see  below).  For the 1993,  1994,  and 1995  fiscal
periods,  the Series' Class A shares paid no  Distribution  Plan expenses.
For the fiscal  periods  ending  December 31, 1993 and 1994,  CSC received
sales  charges  in  excess  of  the  dealer  reallowance  of  $72,396  and
$16,975,  respectively.  For fiscal 1995,  CDI received  sales  charges in
excess of the dealer reallowance of $5,163.
         Pursuant to Rule 12b-1 under the  Investment  Company Act of 1940
("1940  Act"),  the Series has adopted  Distribution  Plans (the  "Plans")
which permit it to pay certain  expenses  associated with the distribution
of its shares.  Such expenses may not exceed,  on an annual  basis,  0.25%
of the  Series'  Class A average  daily  net  assets.  Expenses  under the
Class C Plan may not  exceed,  on an  annual  basis,  0.80% of the Class C
average   daily  net  assets.   The   Series'   Class  C  shares  paid  no
Distribution  Plan  expenses in 1993,  since those shares were not offered
to the  public at that time.  For the 1994 and 1995  fiscal  periods,  the
Series'  Class C shares  paid  Distribution  Plan  expenses of $16,753 and
$28,141, respectively.
         The  Plans  were  approved  by the  Board of  Directors/Trustees,
including the  Directors/Trustees  who are not "interested persons" of the
Funds  (as that  term is  defined  in the 1940 Act) and who have no direct
or indirect  financial  interest in the  operation  of the Plans or in any
agreements  related to the Plans.  The  selection  and  nomination  of the
Directors/Trustees   who  are  not  interested  persons  of  the  Fund  is
committed to the discretion of such disinterested  Directors/Trustees.  In
establishing  the  Plans,  the   Directors/Trustees   considered   various
factors    including   the   amount   of   the   distribution   fee.   The
Directors/Trustees  determined that there is a reasonable  likelihood that
the Plans will benefit the Funds and their shareholders.
         The  Plans  may  be  terminated  by  vote  of a  majority  of the
non-interested   Directors/Trustees   who  have  no  direct  or   indirect
financial  interest  in  the  Plans,  or by  vote  of a  majority  of  the
outstanding  shares of the Series and class.  Any change in the Plans that
would  materially  increase the  distribution  cost to the Series requires
approval of the shareholders of the affected class;  otherwise,  the Plans
may be  amended by the  Directors/Trustees,  including  a majority  of the
non-interested Directors/Trustees as described above.
         The Plans will  continue  in effect  successive  one-year  terms,
provided that such  continuance is  specifically  approved by (i) the vote
of a majority of the  Directors/Trustees  who are not parties to the Plans
or  interested  persons  of any  such  party  and who  have no  direct  or
indirect  financial  interest  in  the  Plans,  and  (ii)  the  vote  of a
majority of the entire Board of Directors/Trustees.
         Apart from the Plans,  the  Advisor,  at its  expense,  may incur
costs and pay expenses  associated with the  distribution of shares of the
Funds.
    

==========================================================================
                 TRANSFER AND SHAREHOLDER SERVICING AGENT
==========================================================================

         Calvert  Shareholder  Services,  Inc.,  a  subsidiary  of Calvert
Group,  Ltd., and Acacia  Mutual,  has been retained by the Fund to act as
transfer  agent,  dividend  disbursing  agent  and  shareholder  servicing
agent.   These   responsibilities   include:   responding  to  shareholder
inquiries  and  instructions  concerning  their  accounts;  crediting  and
debiting  shareholder  accounts  for  purchases  and  redemptions  of Fund
shares and  confirming  such  transactions;  daily updating of shareholder
accounts to reflect  declaration  and payment of dividends;  and preparing
and distributing  semi-annual  statements to shareholders  regarding their
accounts.   For  such  services,   Calvert  Shareholder  Services,   Inc.,
receives  compensation  based on the number of  shareholder  accounts  and
the  number  of  transactions.  The fees  paid by the  Series  to  Calvert
Shareholder  Services,  Inc. for fiscal periods 1993,  1994, and 1995 were
$16,897, $22,368, and $24,388, respectively.

==========================================================================
                  INDEPENDENT ACCOUNTANTS AND CUSTODIANS
==========================================================================

   
         Coopers  and  Lybrand  L.L.P.  has been  selected by the Board of
Directors  to  serve as  independent  accountants  of the Fund for  fiscal
year 1996.  State Street Bank & Trust Company,  N.A., 225 Franklin Street,
Boston,  MA 02110,  serves as custodian of the Fund's  investments.  First
National Bank of Maryland,  25 South Charles Street,  Baltimore,  Maryland
21203 acts as custodian of certain of the  Series's  cash assets.  Neither
custodian has any part in deciding the Fund's  investment  policies or the
choice of securities that are to be purchased or sold by the Fund.
    

==========================================================================
                          PORTFOLIO TRANSACTIONS
==========================================================================

         Portfolio  transactions  are  undertaken  on the  basis  of their
desirability from an investment  standpoint.  Investment decisions and the
choice of brokers  and dealers  are made by the Fund's  Advisor  under the
direction and supervision of the Fund's Board of Directors.
         Broker-dealers  who execute  portfolio  transactions on behalf of
the Fund are selected on the basis of their  professional  capability  and
the value and quality of their  services.  The Advisor  reserves the right
to place  orders for the  purchase or sale of  portfolio  securities  with
broker-dealers  who have  sold  shares  of CCMIF  or who  provide  it with
statistical,  research,  or other  information and services.  Although any
statistical  research  or  other  information  and  services  provided  by
broker-dealers  may be useful to the  Advisor,  the  dollar  value of such
information   and   services   is   generally   indeterminable,   and  its
availability   or  receipt  does  not  serve  to  materially   reduce  the
Advisor's   normal   research   activities   or  expenses.   No  brokerage
commissions  have been paid to any  officer or director of the Fund or any
of  their  affiliates,  or  broker-dealers  for the  1993,  1994,  or 1995
fiscal periods.
         The  Advisor  may also  execute  portfolio  transactions  with or
through  broker-dealers  who have sold shares of the Fund.  However,  such
sales   will  not  be  a   qualifying   or   disqualifying   factor  in  a
broker-dealer's  selection nor will the selection of any  broker-dealer be
based on the volume of Fund  shares  sold.  The  Advisor or its  affiliate
may compensate,  at its expense,  such  broker-dealers in consideration of
their promotional and administrative services.
         The  portfolio  turnover  for the  1993,  1994,  and 1995  fiscal
periods was 21%, 68%, and 47%, respectively.

==========================================================================
                           GENERAL INFORMATION
==========================================================================

         The  Fund  was  organized  as a  corporation  under  the  General
Corporation  Law of the State of Maryland on February 4, 1992.  The Fund's
other series are: Calvert National  Municipal  Intermediate  Fund, Calvert
Arizona   Municipal   Intermediate   Fund,   Calvert  Maryland   Municipal
Intermediate Fund,  Calvert Michigan Municipal  Intermediate Fund, Calvert
New York  Municipal  Intermediate  Fund,  Calvert  Pennsylvania  Municipal
Intermediate  Fund,  and Calvert  Virginia  Municipal  Intermediate  Fund.
Prior to March 1, 1994, Calvert National  Municipal  Intermediate Fund was
known as Calvert Intermediate Municipal Fund.
         CCMIF  will  send  its  shareholders  unaudited  semi-annual  and
audited  annual  reports that will include the Series' net asset value per
share,  portfolio  securities,  income and expenses,  and other  financial
information.
         This  Statement of  Additional  Information  does not contain all
the information in the Fund's  registration  statement.  The  registration
statement is on file with the  Securities  and Exchange  Commission and is
available to the public.
         Each  share  of the  Series  represents  an  equal  proportionate
interest  in that  Series  with each other  share and is  entitled to such
dividends and  distributions  out of the income belonging to the Series as
declared by the Board.  The Series offers two separate  classes of shares:
Class  A and  Class  C.  Each  class  represents  interests  in  the  same
portfolio of  investments  but, as further  described  in the  Prospectus,
each class is subject to  differing  sales  charges  and  expenses,  which
will result in  differing  net asset  values and  distributions.  Upon any
liquidation  of the  Series,  shareholders  of each class are  entitled to
share pro rata in the net assets available for distribution.

==========================================================================
                           FINANCIAL STATEMENTS
==========================================================================

   
         The audited  financial  statements  in the Series'  Annual Report
to  Shareholders,  dated December 31, 1995, are expressly  incorporated by

                                 APPENDIX
==========================================================================

Municipal Obligations
         Municipal  obligations  are debt  obligations  issued by  states,
cities,  municipalities,  and their  agencies to obtain  funds for various
public  purposes.  Such purposes  include the construction of a wide range
of public  facilities,  the  refunding  of  outstanding  obligations,  the
obtaining  of funds for  general  operating  expenses,  and the lending of
funds to other public  institutions and facilities.  In addition,  certain
types of  industrial  development  bonds  are  issued  by or on  behalf of
public  authorities  to obtain  funds for many  types of local,  privately
operated  facilities.  Such  debt  instruments  are  considered  municipal
obligations  if the interest  paid on them is exempt from  federal  income
tax in the opinion of bond  counsel to the issuer.  Although  the interest
paid  on  the  proceeds   from  private   activity   bonds  used  for  the
construction,  equipment,  repair or  improvement  of  privately  operated
industrial  or  commercial  facilities  may be exempt from federal  income
tax,  current federal tax law places  substantial  limitations on the size
of such issues.
         Municipal   obligations   are  generally   classified  as  either
"general  obligation" or "revenue''  bonds.  General  obligation bonds are
secured by the issuer's  pledge of its faith,  credit and taxing power for
the payment of  principal  and  interest.  Revenue  bonds are payable from
the revenues  derived from a  particular  facility or class of  facilities
or, in some  cases,  from the  proceeds  of a special  excise tax or other
specific   revenue  source,   but  not  from  the  general  taxing  power.
Tax-exempt  industrial  development  bonds are in most cases revenue bonds
and do not  generally  carry  the  pledge  of the  credit  of the  issuing
municipality.  There  are,  of  course,  variations  in  the  security  of
municipal obligations,  both within a particular  classification and among
classifications.
         Municipal  obligations  are  generally  traded  on the basis of a
quoted  yield to  maturity,  and the price of the  security is adjusted so
that  relative  to the stated  rate of  interest it will return the quoted
rate to the purchaser.
         Short-term and  limited-term  municipal  obligations  include Tax
Anticipation Notes,  Revenue  Anticipation Notes, Bond Anticipation Notes,
Construction  Loan Notes,  and Discount  Notes.  The  maturities  of these
instruments  at the time of  issue  generally  will  range  between  three
months and one year.  Pre-Refunded  Bonds with longer  nominal  maturities
that are due to be retired  with the  proceeds of an  escrowed  subsequent
issue  at a  date  within  one  year  and  three  years  of  the  time  of
acquisition  are also  considered  short-term and  limited-term  municipal
obligations.

Municipal Bond and Note Ratings
Description  of Moody's  Investors  Service,  Inc.'s  ratings of state and
municipal notes:
         Moody's   ratings  for  state  and  municipal   notes  and  other
short-term  obligations are designated  Moody's  Investment Grade ("MIG").
This distinction is in recognition of the differences  between  short-term
credit risk and long-term risk.
         MIG 1: Notes  bearing this  designation  are of the best quality,
enjoying  strong  protection  from  established  cash  flows of funds  for
their servicing or from  established and broad-based  access to the market
for refinancing, or both.
         MIG2:  Notes bearing this  designation are of high quality,  with
margins of  protection  ample  although  not so large as in the  preceding
group.
         MIG3:  Notes bearing this  designation are of favorable  quality,
with all  security  elements  accounted  for but  lacking  the  undeniable
strength  of the  preceding  grades.  Market  access for  refinancing,  in
particular, is likely to be less well established.
         MIG4:  Notes bearing this  designation  are of adequate  quality,
carrying  specific  risk  but  having  protection   commonly  regarded  as
required of an investment  security and not  distinctly  or  predominantly
speculative.

Description  of  Moody's  Investors   Service   Inc.'s/Standard  &  Poor's
municipal bond ratings:
         Aaa/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.  This  rating  indicates  an  extremely  strong
capacity to pay principal and interest.
         Aa/AA:   Bonds  rated  AA  also  qualify  as  high-quality   debt
obligations.  Capacity to pay principal  and interest is very strong,  and
in the  majority  of  instances  they differ from AAA issues only in small
degree.  They are rated  lower  than the best  bonds  because  margins  of
protection  may  not be as  large  as in Aaa  securities,  fluctuation  of
protective  elements  may be of greater  amplitude,  or there may be other
elements  present which make long-term  risks appear  somewhat larger than
in Aaa securities.
         A/A:  Upper-medium grade obligations.  Factors giving security to
principal  and  interest  are  considered  adequate,  but  elements may be
present  which make the bond  somewhat  more  susceptible  to the  adverse
effects of circumstances and economic conditions.
         Baa/BBB:  Medium  grade  obligations;  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.
         Ba/BB,  B/B,  Caa/CCC,  Ca/CC:  Debt rated in these categories is
regarded  as  predominantly  speculative  with  respect to capacity to pay
interest and repay principal.  There may be some large  uncertainties  and
major  risk  exposure  to  adverse  conditions.  The  higher the degree of
speculation, the lower the rating.
         C/C: This rating is only for no-interest income bonds.
         D: Debt in default;  payment of interest  and/or  principal is in
arrears.

                             LETTER OF INTENT

Calvert Distributors, Inc.

Bethesda, MD 20814

Ladies and Gentlemen:

         By signing this Letter of Intent, or affirmatively marking the
Letter of Intent option on my Fund Account Application Form, I agree to
be bound by the terms and conditions applicable to Letters of Intent
appearing in the Prospectus and the Statement of Additional Information
for the Fund and the provisions described below as they may be amended
from time to time by the Fund. Such amendments will apply automatically
to existing Letters of Intent.

         I intend to invest in the shares of:     (Fund or Portfolio name<F4>*)
during the thirteen (13) month period from the date
of my first purchase pursuant to this Letter (which cannot be more than
ninety (90) days prior to the date of this Letter or my Fund Account
Application Form, whichever is applicable), an aggregate amount
(excluding any reinvestments of distributions) of at least fifty
thousand dollars ($50,000) which, together with my current holdings of
the Fund (at public offering price on date of this Letter or my Fund
Account Application Form, whichever is applicable), will equal or exceed
the amount checked below:

<F4> *"Fund" in this Letter of Intent shall refer to the Fund or Portfolio,
as the case may be, here indicated.

         __ $50,000 __ $100,000 __ $250,000 __ $500,000 __ $1,000,000

         Subject to the conditions specified below, including the terms
of escrow, to which I hereby agree, each purchase occurring after the
date of this Letter will be made at the public offering price applicable
to a single transaction of the dollar amount specified above, as
described in the Fund's prospectus. No portion of the sales charge
imposed on purchases made prior to the date of this Letter will be
refunded.

         I am making no commitment to purchase shares, but if my
purchases within thirteen months from the date of my first purchase do
not aggregate the minimum amount specified above, I will pay the
increased amount of sales charges prescribed in the terms of escrow
described below. I understand that 4.75% of the minimum dollar amount
specified above will be held in escrow in the form of shares (computed
to the nearest full share). These shares will be held subject to the
terms of escrow described below.

         From the initial purchase (or subsequent purchases if
necessary), 4.75% of the dollar amount specified in this Letter shall be
held in escrow in shares of the Fund by the Fund's transfer agent. For
example, if the minimum amount specified under the Letter is $50,000,
the escrow shall be shares valued in the amount of $2,375 (computed at
the public offering price adjusted for a $50,000 purchase). All
dividends and any capital gains distribution on the escrowed shares will
be credited to my account.

         If the total minimum investment specified under the Letter is
completed within a thirteen month period, escrowed shares will be
promptly released to me. However, shares disposed of prior to completion
of the purchase requirement under the Letter will be deducted from the
amount required to complete the investment commitment.

         Upon expiration of this Letter, the total purchases pursuant to
the Letter are less than the amount specified in the Letter as the
intended aggregate purchases, Calvert Distributors, Inc. ("CDI") will
bill me for an amount equal to the difference between the lower load I
paid and the dollar amount of sales charges which I would have paid if
the total amount purchased had been made at a single time. If not paid
by the investor within 20 days, CDI will debit the difference from my
account. Full shares, if any, remaining in escrow after the
aforementioned adjustment will be released and, upon request, remitted
to me.

         I irrevocably constitute and appoint CDI as my
attorney-in-fact, with full power of substitution, to surrender for
redemption any or all escrowed shares on the books of the Fund. This
power of attorney is coupled with an interest.

         The commission allowed by Calvert Distributors, Inc. to the
broker-dealer named herein shall be at the rate applicable to the
minimum amount of my specified intended purchases.

         The Letter may be revised upward by me at any time during the
thirteen-month period, and such a revision will be treated as a new
Letter, except that the thirteen-month period during which the purchase
must be made will remain unchanged and there will be no retroactive
reduction of the sales charges paid on prior purchases.

         In determining the total amount of purchases made hereunder,
shares disposed of prior to termination of this Letter will be deducted.
My broker-dealer shall refer to this Letter of Intent in placing any
future purchase orders for me while this Letter is in effect.

==========================================================================
                           INVESTMENT OBJECTIVE
==========================================================================

     Approximately February 23, 1996, a proxy statement was mailed to Calvert 
National Municipal Intermediate Fund ("National Municipal" or the "Series")
shareholders were asked to approve certain changes in investment restrictions, 
including the ability to purchase futures and options and non-investment grade
bonds, and to make the Series mondiversified. The shareholder meeting scheduled
for April 18, 1996 was adjourned, but shareholder approval of all items was
expected on or about April 30, 1996.
         Calvert   National   Municipal   Intermediate   Fund   ("National
Municipal"  or  the  "Series")  is  designed  to  provide  individual  and
institutional  investors with the highest level of interest  income exempt
from  federal  income  taxes  as is  consistent  with  prudent  investment
management,   preservation  of  capital,  and  the  quality  and  maturity
characteristics  of the Series.  There is, of course,  no  assurance  that
the Series will be successful in meeting its investment  objective;  there
are inherent risks in the ownership of any investment.
         Dividends  paid by National  Municipal will fluctuate with income
earned on investments.  In addition,  the dividends and distributions paid
and the value of each  share  will vary by class of  shares;  the value of
its shares will  fluctuate  to reflect  changes in the market value of the
Series'   investments.   The  Series   will   attempt,   through   careful
management,  to reduce  these  risks and  enhance  the  opportunities  for
higher income and greater price stability.

==========================================================================
                           INVESTMENT POLICIES
==========================================================================

         National   Municipal   invests   primarily  in  a  nondiversified
portfolio of municipal  obligations,  including  some with  interest  that
may be subject to  alternative  minimum tax.  The average  dollar-weighted
maturity  of   investments   is  between  3  and  10  years.   Fixed  rate
investments  normally  have  remaining  maturities  of 12  years  or less;
variable  rate  investments  may  have  longer   maturities.   A  complete
explanation of municipal  obligations  and municipal bond and note ratings
appears in the Appendix.
         Under normal market  conditions,  National  Municipal will invest
at least 65% of its total assets in municipal  obligations  with  interest
that is exempt from  federal  income  tax.  To the extent the  obligations
are  issued  by your  state  of  residence,  you may also be  exempt  from
certain state and local income taxes.

Variable Rate Demand Notes
         The Board of  Directors  of Calvert  Municipal  Fund,  Inc.  (the
"Fund"),   of  which  National   Municipal  is  a  series,   has  approved
investments   in  floating  and  variable   rate  demand  notes  upon  the
following  conditions:  the Series has right of demand, upon notice not to
exceed  thirty  days,  against the issuer to receive  payment;  the issuer
will be able to  make  payment  upon  such  demand,  either  from  its own
resources or through an  unqualified  commitment  from a third party;  and
the rate of  interest  payable  is  calculated  to ensure  that the market
value of such notes will  approximate  par value on the adjustment  dates.
The  remaining  maturity  of  such  demand  notes  is  deemed  the  period
remaining  until  such time as the  Series has the right to dispose of the
notes at a price which  approximates  par and market  value.  Notes with a
right of demand  exceeding  seven  days are  considered  illiquid  and are
subject to purchase restrictions.

Municipal Leases
         National   Municipal   may  invest  in   municipal   leases,   or
structured  instruments  where  the  underlying  security  is a  municipal
lease.   A  municipal   lease  is  an   obligation   of  a  government  or
governmental  authority,  not subject to voter  approval,  used to finance
capital  projects or equipment  acquisitions  and payable through periodic
rental  payments.  National  Municipal may purchase  unrated  leases.  The
Fund's    Advisor,    under    the    supervision    of   the   Board   of
Trustees/Directors,  is responsible  for determining the credit quality of
such  leases  on  an  ongoing  basis,   including  an  assessment  of  the
likelihood that the lease will not be canceled.  Certain  municipal leases
may be considered  illiquid and subject to National  Municipal's  limit on
illiquid  securities.  The Board of  Trustees/Directors  has  directed the
Advisor to treat a municipal  lease as a liquid  security if it  satisfies
the following  conditions:  (A) such  treatment  must be  consistent  with
National Municipal's  investment  restrictions;  (B) the Advisor should be
able  to  conclude  that  the  obligation   will  maintain  its  liquidity
throughout  the  time it is  held  by  National  Municipal,  based  on the
following  factors:  (1)  whether  the  lease  may  be  terminated  by the
lessee;  (2) the  potential  recovery,  if any,  from a sale of the leased
property upon  termination of the lease;  (3) the lessee's  general credit
strength  (e.g.,   its  debt,   administrative,   economic  and  financial
characteristics  and  prospects);  (4) the likelihood that the lessee will
discontinue  appropriating  funding  for the leased  property  because the
property  is no longer  deemed  essential  to its  operations  (e.g.,  the
potential  for  an  "event  of  nonappropriation"),  and  (5)  any  credit
enhancement or legal recourse  provided upon an event of  nonappropriation
or other  termination  of the  lease;  (C) the  Advisor  should  determine
whether  the  obligation  can be  disposed  of  within  seven  days in the
ordinary  course  of  business  at  approximately   the  amount  at  which
National  Municipal  has valued it for  purposes of  calculating  National
Municipal's  net asset value,  taking into account the following  factors:
(1) the frequency of trades and quotes;  (2) the  volatility of quotations
and trade  prices;  (3) the number of dealers  willing to purchase or sell
the  security  and  the  number  of  potential   purchasers;   (4)  dealer
undertakings  to make a market  in the  security;  (5) the  nature  of the
security and the nature of the marketplace  trades (e.g.,  the time needed
to  dispose of the  security,  the method of  soliciting  offers,  and the
mechanics  of the  transfer);  (6)  the  rating  of the  security  and the
financial  condition  and  prospects of the issuer;  and (7) other factors
relevant to National  Municipal's ability to dispose of the security;  and
(D) the Advisor  should have  reasonable  expectations  that the municipal
lease  obligation  will  maintain its  liquidity  throughout  the time the
instrument is held by National Municipal.

Temporary Investments
         Short-term   money   market   type   investments    consist   of:
obligations of the U.S.  Government,  its agencies and  instrumentalities;
certificates  of deposit of banks with  assets of one  billion  dollars or
more;  commercial  paper or  other  corporate  notes  of  investment-grade
quality;   and  any  of  such  items  subject  to  short-term   repurchase
agreements.

When-Issued Purchases
         Securities  purchased on a when-issued  basis and the  securities
held in National  Municipal's  portfolio  are subject to changes in market
value based on the  public's  perception  of the  creditworthiness  of the
issuer and changes in the level of interest  rates  (which will  generally
result  in  both   changing  in  value  in  the  same  way,   i.e.,   both
experiencing  appreciation  when interest  rates decline and  depreciation
when  interest  rates  rise).  Therefore,  if in order to  achieve  higher
interest income,  National Municipal remains  substantially fully invested
at the  same  time  that  it has  purchased  securities  on a  when-issued
basis,  there will be a greater  possibility  that the market value of its
assets  may  vary.  No new  when-issued  commitments  will be made if more
than 50% of the Series' net assets would become so committed.
         When the time comes to pay for when-issued  securities,  National
Municipal will meet its  obligations  from then available cash flow,  sale
of  securities  or,  although it would not normally  expect to do so, from
sale of the  when-issued  securities  themselves  (which may have a market
value  greater  or less  than the  Series'  payment  obligation).  Sale of
securities to meet such  obligations  carries with it a greater  potential
for the  realization  of capital  losses and  capital  gains which are not
exempt from federal income tax.

   
Transactions in Futures Contracts (effective upon shareholder approval)
         National  Municipal  may  engage  in the  purchase  and  sale  of
futures  contracts  on an index  of  municipal  bonds or on U.S.  Treasury
securities,  or  options  on  such  futures  contracts,  for  hedging  and
substitution  purposes  only.  National  Municipal  may sell such  futures
contracts in  anticipation  of a decline in the cost of municipal bonds it
holds  or may  purchase  such  futures  contracts  in  anticipation  of an
increase in the value of municipal  bonds  National  Municipal  intends to
acquire.  National  Municipal  also is  authorized  to  purchase  and sell
other financial  futures  contracts which in the opinion of the Investment
Advisor  provide  an  appropriate  hedge  for  some  or  all  of  National
Municipal's securities.
         Because of low initial  margin  deposits made upon the opening of
a futures position,  futures  transactions  involve substantial  leverage.
As a  result,  relatively  small  movements  in the  price of the  futures
contract can result in  substantial  unrealized  gains or losses.  Because
National  Municipal  will  engage in the  purchase  and sale of  financial
futures contracts solely for hedging and substitution  purposes,  however,
any losses  incurred in connection  therewith  should,  if the strategy is
successful,  be  offset in whole or in part by  increases  in the value of
securities  held by  National  Municipal  or  decreases  in the  price  of
securities National Municipal intends to acquire.
         Municipal  bond  index  futures  contracts  commenced  trading in
June 1985,  and it is  possible  that  trading in such  futures  contracts
will be less liquid than that in other futures  contracts.  The trading of
futures  contracts  and  options  thereon is  subject  to  certain  market
risks,  such as trading  halts,  suspensions,  exchange or clearing  house
equipment  failures,  government  intervention  or  other  disruptions  of
normal  trading  activity,  which  could at  times  make it  difficult  or
impossible to liquidate existing positions.
         The liquidity of a secondary  market in futures  contracts may be
further   adversely   affected  by  "daily   price   fluctuation   limits"
established  by contract  markets,  which limit the amount of  fluctuation
in the  price of a futures  contract  or  option  thereon  during a single
trading  day.  Once the daily limit has been reached in the  contract,  no
trades may be entered  into at a price beyond the limit,  thus  preventing
the  liquidation of open positions.  Prices of existing  contracts have in
the past moved the daily limit on a number of  consecutive  trading  days.
National  Municipal  will  enter into a futures  position  only if, in the
judgment  of the  Investment  Advisor,  there  appears  to be an  actively
traded secondary market for such futures contracts.
         The  successful  use of  transactions  in futures  contracts  and
options  thereon  depends  on the  ability  of the  Investment  Advisor to
correctly  forecast the direction  and extent of price  movements of these
instruments,  as  well  as  price  movements  of the  securities  held  by
National  Municipal  within a given time frame. To the extent these prices
remain stable  during the period in which a futures or option  contract is
held  by  National  Municipal,  or move in a  direction  opposite  to that
anticipated,  National  Municipal  may  realize  a  loss  on  the  hedging
transaction  which is not fully or partially  offset by an increase in the
value  of  National  Municipal's   securities.   As  a  result,   National
Municipal's  total  return for such  period may be less than if it had not
engaged in the hedging transaction.


Description of Financial Futures Contracts (effective upon shareholder 
approval)
         
     Futures  Contracts.  A futures contract obligates the seller of a
contract to deliver and the  purchaser  of a contract to take  delivery of
the type of  financial  instrument  called for in the contract or, in some
instances,  to make a cash  settlement,  at a specified  future time for a
specified  price.  Although  the  terms  of a  contract  call  for  actual
delivery or acceptance of securities,  or for a cash  settlement,  in most
cases the  contracts  are closed out before the delivery  date without the
delivery or acceptance taking place.  National  Municipal intends to close
out any futures contracts prior to the delivery date of such contracts.
         National  Municipal  may sell futures  contracts in  anticipation
of a decline  in the value of its  investments  in  municipal  bonds.  The
loss associated  with any such decline could be reduced without  employing
futures  as  a  hedge  by   selling   long-term   securities   and  either
reinvesting  the  proceeds in  securities  with shorter  maturities  or by
holding  assets  in  cash.  This  strategy,   however,  entails  increased
transaction  costs  in  the  form  of  brokerage  commissions  and  dealer
spreads and will typically reduce National  Municipal's  average yields as
a result of the shortening of maturities.
         The  purchase  or sale of a  futures  contract  differs  from the
purchase  or sale of a  security,  in that no price or  premium is paid or
received.   Instead,  an  amount  of  cash  or  securities  acceptable  to
National   Municipal's   futures  commission  merchant  and  the  relevant
contract  market,  which varies but is  generally  about 5% or less of the
contract amount,  must be deposited with the broker.  This amount is known
as "initial  margin," and represents a "good faith"  deposit  assuring the
performance  of both  the  purchaser  and the  seller  under  the  futures
contract.   Subsequent   payments  to  and  from  the  broker,   known  as
"variation  margin,"  are  required  to be made on a  daily  basis  as the
price  of the  futures  contract  fluctuates,  making  the  long or  short
positions in the futures  contract more or less valuable,  a process known
as "marking to the market."  Prior to the  settlement  date of the futures
contract,  the position  may be closed out by taking an opposite  position
which will operate to terminate  the position in the futures  contract.  A
final  determination of variation margin is then made,  additional cash is
required  to be paid  to or  released  by the  broker,  and the  purchaser
realizes  a loss  or  gain.  In  addition,  a  commission  is paid on each
completed purchase and sale transaction.
         The sale of financial futures  contracts  provides an alternative
means of hedging National  Municipal  against declines in the value of its
investments  in  municipal  bonds.  As such values  decline,  the value of
National  Municipal's  position  in the  futures  contracts  will  tend to
increase,  thus  offsetting  all or a portion of the  depreciation  in the
market value of National  Municipal's  fixed income  investments which are
being hedged.  While National Municipal will incur commission  expenses in
establishing  and closing out futures  positions,  commissions  on futures
transactions  may be significantly  lower than transaction  costs incurred
in the  purchase  and sale of fixed income  securities.  In addition,  the
ability  of  National  Municipal  to trade in the  standardized  contracts
available  in the  futures  market  may  offer  a more  effective  hedging
strategy  than a program  to reduce  the  average  maturing  of  portfolio
securities,   due  to  the  unique  and   varied   credit  and   technical
characteristics  of the municipal debt  instruments  available to National
Municipal.   Employing  futures  as  a  hedge  may  also  permit  National
Municipal to assume a hedging  posture  without  reducing the yield on its
investments, beyond any amounts required to engage in futures trading.
         National  Municipal  may  engage  in the  purchase  and  sale  of
futures contracts on an index of municipal  securities.  These instruments
provide  for  the  purchase  or  sale  of  a  hypothetical   portfolio  of
municipal bonds at a fixed price in a stated  delivery month.  Unlike most
other  futures   contracts,   however,  a  municipal  bond  index  futures
contract does not require  actual  delivery of securities but results in a
cash  settlement  based upon the  difference in value of the index between
the time the contract was entered into and the time it is liquidated.
         The  municipal  bond  index  underlying  the  futures   contracts
traded  by  the  Portfolio  is  The  Bond  Buyer   Municipal  Bond  Index,
developed by The Bond Buyer and the Chicago  Board of Trade  ("CBT"),  the
contract  market on which the futures  contracts are traded.  As currently
structured,  the  index  is  comprised  of 40  tax-exempt  term  municipal
revenue  and general  obligation  bonds.  Each bond  included in the index
must be rated  either A- or higher by  Standard & Poor's or A or higher by
Moody's Investors  Service and must have a remaining  maturity of 19 years
or  more.   Twice  a  month  new   issues   satisfying   the   eligibility
requirements  are added to,  and an equal  number  of old  issues  will be
deleted  from,  the  index.  The  value  of the  index is  computed  daily
according  to a formula  based  upon the price of each bond in the  index,
as evaluated by four dealer-to-dealers brokers.
         National  Municipal may also purchase and sell futures  contracts
on U.S.  Treasury  bills,  notes and bonds for the same  types of  hedging
and substitution  purposes.  Such futures  contracts  provide for delivery
of the underlying  security at a specified  future time for a fixed price,
and the  value of the  futures  contract  therefore  generally  fluctuates
with movements in interest rates.
         The municipal bond index futures  contract,  futures contracts on
U.S.  Treasury  securities  and  options  on such  futures  contracts  are
traded  on the CBT,  which,  like  other  contract  markets,  assures  the
performance  of the parties to each  futures  contract  through a clearing
corporation,   a   nonprofit   organization   managed   by  the   exchange
membership,  which is also  responsible  for handling daily  accounting of
deposits or withdrawals of margin.
         National   Municipal   may  also   purchase   financial   futures
contracts when not fully invested in municipal  bonds,  in anticipation of
an  increase  in the cost of  securities  National  Municipal  intends  to
purchase.  As such  securities  are  purchased,  an  equivalent  amount of
futures  contracts will be closed out. In a substantial  majority of these
transactions,  National  Municipal  will  purchase  municipal  bonds  upon
termination of the futures  contracts.  Due to changing market  conditions
and  interest  rate  forecasts,   however,   a  futures  position  may  be
terminated without a corresponding  purchase of securities.  Nevertheless,
all purchases of futures  contracts by National  Municipal will be subject
to certain restrictions, described below.
         Options on  Futures  Contracts.  An option on a futures  contract
provides the purchaser with the right,  but not the  obligation,  to enter
into  a long  position  in  the  underlying  futures  contract  (that  is,
purchase  the  futures  contract),  in the case of a "call"  option,  or a
short  position  (sell  the  futures  contract),  in the  case  of a "put"
option,  for a fixed price up to a stated  expiration  date. The option is
purchased  for  a  non-refundable   fee,  known  as  the  "premium."  Upon
exercise of the option,  the contract  market  clearing house assigns each
party  to the  option  an  opposite  position  in the  underlying  futures
contract.  In the event of  exercise,  therefore,  the parties are subject
to all of the risks of futures  trading,  such as  payment of initial  and
variation margin.  In addition,  the seller, or "writer," of the option is
subject  to  margin  requirements  on  the  option  position.  Options  on
futures  contracts  are  traded  on  the  same  contract  markets  as  the
underlying futures contracts.
         National  Municipal  may  purchase  options on futures  contracts
for the  same  types  of  purposes  described  above  in  connection  with
futures   contracts.   For  example,   in  order  to  protect  against  an
anticipated  decline  in  the  value  of  securities  it  holds,  National
Municipal  could  purchase  put options on futures  contracts,  instead of
selling  the  underlying  futures  contracts.   Conversely,  in  order  to
protect  against  the  adverse  effects of  anticipated  increases  in the
costs of  securities to be acquired,  National  Municipal  could  purchase
call options on futures  contracts,  instead of purchasing  the underlying
futures  contracts.  National  Municipal  generally  will sell  options on
futures contracts only to close out an existing position.
         National  Municipal  will  not  engage  in  transactions  in such
instruments  unless  and  until the  Investment  Advisor  determines  that
market  conditions and the  circumstances  of National  Municipal  warrant
such trading.  To the extent  National  Municipal  engages in the purchase
and sale of futures  contracts or options  thereon,  it will do so only at
a level  which  is  reflective  of the  Investment  Advisor's  view of the
hedging  needs of  National  Municipal,  the  liquidity  of the market for
futures  contracts and the anticipated  correlation  between  movements in
the value of the futures or option  contract  and the value of  securities
held by National Municipal.
         Restrictions  on the Use of  Futures  Contracts  and  Options  on
Futures  Contracts.  Under  regulations of the Commodity  Futures  Trading
Commission  ("CFTC"),  the futures  trading  activities  described  herein
will not result in  National  Municipal  being  deemed to be a  "commodity
pool," as defined under such  regulations,  provided that certain  trading
restrictions  are  adhered to. In  particular,  CFTC  regulations  require
that all futures and option positions  entered into by National  Municipal
qualify  as  bona  fide  hedge   transactions,   as  defined   under  CFTC
regulations,  or,  in the case of long  positions,  that the value of such
positions  not  exceed  an  amount  of  segregated   funds  determined  by
reference  to  certain  cash  and  securities   positions   maintained  by
National  Municipal and accrued  profits on such  positions.  In addition,
as a matter of operating  policy,  National  Municipal may not purchase or
sell a futures contract or an option thereon if,  immediately  thereafter,
the sum of the amount of initial margin  deposits on National  Municipal's
existing  futures  positions  and premiums on such options would exceed 5%
of its net assets.
         When National  Municipal  purchases a futures  contract,  it will
maintain an amount of cash,  cash  equivalents  (for  example,  commercial
paper and daily tender  adjustable  notes) or short-term  high-grade fixed
income  securities  in a  segregated  account  with  National  Municipal's
custodian,  so that the  amount so  segregated  plus the amount of initial
and  variation  margin held in the account of its broker equals the market
value  of the  futures  contract,  thereby  ensuring  that the use of such
futures is unleveraged.
         Risk  Factors  in   Transactions   in  Futures   Contracts.   The
particular  municipal bonds  comprising the index underlying the municipal
bond  index  futures  contract  may vary from the bonds  held by  National
Municipal.  In addition,  the securities  underlying  futures contracts on
U.S.  Treasury  securities  will  not be the  same as  securities  held by
National   Municipal.   As  a   result,   National   Municipal's   ability
effectively  to hedge  all or a  portion  of the  value  of its  municipal
bonds  through  the use of futures  contracts  will  depend in part on the
degree to which price  movements  in the index  underlying  the  municipal
bond index futures contract,  or the U.S. Treasury  securities  underlying
other  futures  contracts  trade,  correlate  with price  movements of the
municipal bonds held by National Municipal.
         For example,  where prices of  securities  in National  Municipal
do not move in the same  direction  or to the same extent as the values of
the  securities  or index  underlying a futures  contract,  the trading of
such futures  contracts may not  effectively  hedge  National  Municipal's
investments  and may  result in trading  losses.  The  correlation  may be
affected by disparities  in the average  maturity,  ratings,  geographical
mix or  structure  of  National  Municipal's  investments  as  compared to
those  comprising the index,  and general  economic or political  factors.
In addition,  the correlation  between movements in the value of the index
underlying  a futures  contract  may be  subject to change  over time,  as
additions  to and  deletions  from the index alter its  structure.  In the
case  of  futures  contracts  on  U.S.  Treasury  securities  and  options
thereon,  the anticipated  correlation of price movements between the U.S.
Treasury  securities  underlying  the  futures  or options  and  municipal
bonds may be adversely  affected by economic,  political,  legislative  or
other  developments  that  have  a  disparate  impact  on  the  respective
markets  for such  securities.  In the event that the  Investment  Advisor
determines  to enter into  transactions  in  financial  futures  contracts
other than the municipal  bond index  futures  contract or futures on U.S.
Treasury securities,  the risk of imperfect  correlation between movements
in the  prices of such  futures  contracts  and the  prices  of  municipal
bonds held by National Municipal may be greater.
         The  trading of futures  contracts  on an index also  entails the
risk of  imperfect  correlation  between  movements  in the  price  of the
futures  contract and the value of the underlying  index.  The anticipated
spread  between  the prices may be  distorted  due to  differences  in the
nature of the  markets,  such as margin  requirements,  liquidity  and the
participation  of  speculators  in  the  futures  markets.   The  risk  of
imperfect  correlation,  however,  generally  diminishes  as the  delivery
month specified in the futures contract approaches.
         Prior  to   exercise  or   expiration,   a  position  in  futures
contracts or options  thereon may be  terminated  only by entering  into a
closing  purchase or sale  transaction.  This requires a secondary  market
on the relevant  contract  market.  National  Municipal  will enter into a
futures  or  option  position  only  if  there  appears  to  be  a  liquid
secondary  market  therefor,  although there can be no assurance that such
a liquid  secondary  market will exist for any particular  contract at any
specific  time.  Thus, it may not be possible to close out a position once
it has been  established.  Under such  circumstances,  National  Municipal
could be  required to make  continuing  daily cash  payments of  variation
margin in the event of adverse  price  movements.  In such  situation,  if
National  Municipal  has  insufficient  cash,  it may be  required to sell
portfolio  securities to meet daily  variation  margin  requirements  at a
time  when  it may be  disadvantageous  to do so.  In  addition,  National
Municipal  may be  required  to perform  under the terms of the futures or
option  contracts it holds.  The inability to close out futures or options
positions  also  could  have an  adverse  impact on  National  Municipal's
ability effectively to hedge its portfolio.
         When  National  Municipal   purchases  an  option  on  a  futures
contract,  its risk is limited to the amount of the premium,  plus related
transaction  costs,  although this entire amount may be lost. In addition,
in order to profit from the  purchase of an option on a futures  contract,
National  Municipal  may be required to exercise the option and  liquidate
the underlying  futures contract,  subject to the availability of a liquid
secondary  market.  The  trading  of options  on  futures  contracts  also
entails  the risk  that  changes  in the value of the  underlying  futures
contract  will  not be  fully  reflected  in  the  value  of  the  option,
although the risk of  imperfect  correlation  generally  tends to diminish
as the maturity  date of the futures  contract or  expiration  date of the
option approaches.
         "Trading  Limits"  or  "Position  Limits"  may also be imposed on
the  maximum  number of  contracts  which any  person  may hold at a given
time. A contract  market may order the  liquidation of positions  found to
be in  violation  of these  limits and it may impose  other  sanctions  or
restrictions.  The  Investment  Advisor  does  not  believe  that  trading
limits  will have any  adverse  impact on the  strategies  for hedging the
National Municipal's investments.
         Further,  the  trading  of  futures  contracts  is subject to the
risk  of the  insolvency  of a  brokerage  firm or  clearing  corporation,
which  could  make  it  difficult  or  impossible  to  liquidate  existing
positions or to recover excess variation margin payments.
         In addition to the risks of imperfect  correlation  and lack of a
liquid  secondary  market for such  instruments,  transactions  in futures
contracts  involve  risks  related to  leveraging  and the  potential  for
incorrect   forecasts  of  the  direction  and  extent  of  interest  rate
movements within a given time frame.


Credit Quality
         As an operating  policy,  (effective upon shareholder approval)
National  Municipal may not invest more than  35%  of  its  net   assets   
in   non-investment   grade   municipal obligations.  As has been the industry
practice,  this  determination  of credit  quality is made at the time the 
Series  acquires  the  obligation. However,  because it is possible that 
subsequent  downgrades  could occur, if an  obligation  held by National 
Municipal  is later  downgraded,  the Advisor,  under the  supervision  of the 
Fund's Board of  Directors,  will consider  whether it is in the best interest
of the  shareholders  to hold or  to  dispose  of  the  obligation.  Among 
the  criteria  that  may  be considered  by the  Advisor  and the  Board are
the  probability  that the obligations  will  be  able  to  make  scheduled 
interest  and  principal payments  in the  future,  the  extent  to which  any 
devaluation  of the obligation  has already  been  reflected  in the Series'
net asset  value, and the total  percentage,  if any, of obligations  currently
rated below investment-grade held by National Municipal.
         Noninvestment-grade  securities  have moderate to poor protection
of principal and interest  payments and have speculative  characteristics.
They involve  greater risk of default or price  declines due to changes in
the  issuer's  creditworthiness  than  investment-grade  debt  securities.
Because  the market for  lower-rated  securities  may be thinner  and less
active  than  for  higher-rated  securities,  there  may be  market  price
volatility  for these  securities  and  limited  liquidity  in the  resale
market.  Market prices for these  securities may decline  significantly in
periods of general economic difficulty or rising interest rates.

Fundamental Investment Restrictions

   
         The   foregoing   investment   objective  and  policies  and  the
following  investment  restrictions  and  fundamental  policies may not be
changed  without  the  consent of the  holders of a majority  of  National
Municipal's  outstanding shares.  Shares have equal rights as to voting. A
majority  of  the  shares  means  the  lesser  of (i)  67%  of the  shares
represented  at a  meeting  at  which  more  than  50% of the  outstanding
shares are  represented or (ii) more than 50% of the  outstanding  shares.
National Municipal may not:
         1)    Purchase   common   stocks,    preferred   stocks,
              warrants, or other equity securities;
         2)    Issue senior securities,  borrow money, or pledge,
              mortgage,  or hypothecate its assets, except as may
              be  necessary to secure  borrowings  from banks for
              temporary or emergency  (not  leveraging)  purposes
              and then in an amount not  greater  than 10% of the
              value of the  Series'  total  assets at the time of
              the borrowing.  Investment  securities  will not be
              purchased while any borrowings are outstanding;
         3)    Make loans  other than  through  the  purchase  of
              money market instruments and repurchase  agreements
              or by the  purchase of bonds,  debentures  or other
              debt  securities.  The  purchase by a Portfolio  of
              all  or a  portion  of  an  issue  of  publicly  or
              privately    distributed    debt   obligations   in
              accordance with its investment objective,  policies
              and  restrictions,  shall not constitute the making
              of a loan.
         4)    Underwrite   the   securities  of  other  issuers,
              except  to  the  extent   that  the   purchase   of
              municipal   obligations  in  accordance   with  the
              Series' investment  objective and policies,  either
              directly  from the issuer,  or from an  underwriter
              for an issuer, may be deemed an underwriting;
         5)    Purchase   or  sell  real   estate,   real  estate
              investment  trust   securities,   commodities,   or
              commodity contracts, or oil and gas interests,  but
              this  shall not  prevent  National  Municipal  from
              investing in municipal  obligations secured by real
              estate or interests therein;
         6)    Purchase or sell physical  commodities except that
              it may enter into  futures  contracts  and  options
              thereon (effective upon shareholder approval);
         7)    Purchase  or  retain  securities  of an  issuer if
              those  directors  of the  Fund,  each of whom  owns
              more than 1/2 of 1% of the  outstanding  securities
              of such  issuer,  together own more than 5% of such
              outstanding securities;
         8)    Invest in companies  for the purpose of exercising
              control;   or   invest  in   securities   of  other
              investment   companies,   except  as  they  may  be
              acquired  as part  of a  merger,  consolidation  or
              acquisition  of  assets,  or in  connection  with a
              trustee's/director's  deferred  compensation  plan,
              as long as  there  is no  duplication  of  advisory
              fees;
         9)    Invest   25%  or  more  of  its   assets   in  any
              particular   industry  or  industries.   Industrial
              development  bonds,  where the payment of principal
              and  interest is the  responsibility  of  companies
              within the same industry,  are grouped  together as
              an "industry."
    

Nonfundamental Investment Restrictions

   
         The  Series  has   adopted   the   following   operating   (i.e.,
nonfundamental)   investment   policies  and  restrictions  which  may  be
changed by the Board of Directors without shareholder  approval.  National
Municipal may not:
         1)   Purchase  illiquid  securities if more than 15% of
              the value of its net assets  would be  invested  in
              such securities;
         2)   Invest  more  than 5% of the  value  of its  total
              assets  in   securities   where  the   payment   of
              principal and interest is the  responsibility  of a
              company or  companies  with less than three  years'
              operating history.
         3)   Purchase  or sell a futures  contract or an option
              thereon if immediately  thereafter,  the sum of the
              amount of initial  margin  deposits  on futures and
              premiums  on such  options  would  exceed 5% of the
              Fund's net assets (effective upon shareholder approval);
         4)   Invest in puts or calls on a  security,  including
              straddles,  spreads,  or  any  combination,  if the
              value of that option premium,  when aggregated with
              the  premiums  on all other  options on  securities
              held by the Fund,  exceeds 5% of the  Fund's  total
              assets (effective upon shareholder approval).
         5)   Effect short sales of securities.  For purposes of
              this    restriction,    transactions   in   futures
              contracts  and options are not deemed to constitute
              selling securities short (effective upon shareholder approval).
         6)   Purchase securities on margin,  except that it may
              make margin  deposits in  connection  with  futures
              contacts or options on futures (effective upon shareholder 
               approval).

                   PURCHASES AND REDEMPTIONS OF SHARES
==========================================================================

         Share  certificates  will be issued at no charge if  requested in
writing by the investor.  No  certificates  will be issued for  fractional
shares (see Prospectus, "How to Sell Your Shares").
         To change  redemption  instructions  already given,  shareholders
must send a written  notice to Calvert Group,  c/o NFDS,  6th Floor,  1004
Baltimore,  Kansas City,  MO 64105,  with a voided copy of a check for the
bank  wiring  instructions  to  be  added.  If a  voided  check  does  not
accompany  the request,  then the request must be signature  guaranteed by
a commercial bank,  savings and loan  association,  trust company,  member
firm of any  national  securities  exchange,  or  certain  credit  unions.
Further  documentation  may be required  from  corporations,  fiduciaries,
and institutional investors.
         The right of  redemption  may be suspended or the date of payment
postponed  for any  period  during  which the New York Stock  Exchange  is
closed (other than customary weekend and holiday  closings),  when trading
on the New York Stock Exchange is restricted,  or an emergency  exists, as
determined  by  the  SEC,  or  if  the   Commission  has  ordered  such  a
suspension for the  protection of  shareholders.  Redemption  proceeds are
normally  mailed or wired the next business day after a proper  redemption
request has been  received,  unless  redemptions  have been  suspended  or
postponed as described above.
         Redemption   proceeds  are  normally   paid  in  cash.   However,
National  Municipal  has the right to redeem  shares in assets  other than
cash for redemption amounts exceeding,  in any 90-day period,  $250,000 or
1% of the net asset value of National Municipal, whichever is less.

Reduced Sales Charges (Class A)
         National  Municipal  imposes  reduced  sales  charges  in certain
situations  in which the Principal  Underwriter  (which offers the Series'
shares  continuously  and on a  "best  efforts"  basis)  and  the  dealers
selling  National  Municipal  shares  may  expect to  realize  significant
economies of scale with respect to such sales.  Generally,  sales costs do
not increase in proportion  to the dollar  amount of the shares sold;  for
example,  the  per-dollar  transaction  cost for a sale to an  investor of
shares  worth  $5,000 is generally  much higher than the  per-dollar  cost
for a sale of shares worth  $1,000,000.  Thus, the applicable sales charge
declines  as a  percentage  of the  dollar  amount of  shares  sold as the
dollar amount increases.
         When a  shareholder  agrees to make  purchases  of shares  over a
period of time totaling a certain  dollar  amount  pursuant to a Letter of
Intent,  the  Underwriter  and  selling  dealers can expect to realize the
economies  of  scale  applicable  to that  stated  goal  amount.  Thus the
Series   imposes  the  sales  charge   applicable   to  the  goal  amount.
Similarly,  the  Underwriter  and selling  dealers  also  experience  cost
savings  when  dealing  with  existing  National  Municipal  shareholders,
enabling  the  Series  to  afford  existing   shareholders  the  Right  of
Accumulation.  The  Underwriter  and  selling  dealers  can also expect to
realize  economies  of scale when  making  sales to the members of certain
qualified  groups which agree to  facilitate  distribution  of the Series'
shares to their  members.  See "Exhibit A - Reduced Sales  Charges" in the
Prospectus.

==========================================================================
                       DIVIDENDS AND DISTRIBUTIONS
==========================================================================

         National  Municipal  declares and pays  monthly  dividends of its
net income to  shareholders  of record as of the close of business on each
designated  monthly record date.  Dividends and distributions  will differ
among the classes.  Net investment  income consists of the interest income
earned  on  investments  (adjusted  for  amortization  of  original  issue
discounts  or  premiums  or market  premiums),  less  estimated  expenses.
Capital  gains,  if  any,  are  normally  paid  once a year  and  will  be
automatically   reinvested  at  net  asset  value  in  additional  shares.
Dividends  and  any   distributions   are   automatically   reinvested  in
additional  shares of the Fund,  unless you elect to have the dividends of
$10 or more paid in cash (by check or by Calvert  Money  Controller).  You
may  also  request  to have  your  dividends  and  distributions  from the
Series  invested  in  shares  of  any  other  Calvert  Group  Fund,  at no
additional  charge.  If you elect to have dividends  and/or  distributions
paid in cash, and the U.S.  Postal  Service  cannot deliver the check,  or
if it remains  uncashed  for six months,  it, as well as future  dividends
and distributions, will be reinvested in additional shares.

==========================================================================
                               TAX MATTERS
==========================================================================

   
         In 1995  National  Municipal  did  qualify  and in 1996  National
Municipal  intends to qualify as a "regulated  investment  company"  under
Subchapter M of the Internal  Revenue Code as amended (the "Code").  By so
qualifying,  it will not be  subject  to federal  income  tax,  nor to the
federal  excise tax imposed by the Tax Reform Act of 1986 (the "Act"),  to
the extent that it  distributes  its net  investment  income and  realized
capital gains.
         National   Municipal's   dividends  of  net   investment   income
constitute   exempt-interest  dividends  on  which  shareholders  are  not
generally   subject  to  federal  income  tax;   however  under  the  Act,
dividends  attributable  to interest  on certain  private  activity  bonds
must be included in federal  alternative  minimum  taxable  income for the
purpose  of  determining  liability  (if  any)  for  individuals  and  for
corporations.   National   Municipal's   dividends  derived  from  taxable
interest  and  distributions  of net  short-term  capital  gains,  whether
taken  in  cash  or  reinvested  in  additional  shares,  are  taxable  to
shareholders  as  ordinary  income and do not  qualify  for the  dividends
received  deduction  for  corporations.  If you held shares for six months
or  less,  losses  must  be  offset  by  the  amount  of   exempt-interest
dividends you received,  and, to the extent of capital gain  distributions
you received,  the loss amount not offset  (disallowed) must be treated as
long-term capital loss.
         A  shareholder  may also be subject to some state and local taxes
on  dividends   and   distributions.   National   Municipal   will  notify
shareholders   annually   about   the  tax   status   of   dividends   and
distributions  paid by the Series and the  amount of  dividends  withheld,
if any, during the previous year.
         The Code  provides  that  interest  on  indebtedness  incurred or
continued in order to purchase or carry  shares of a regulated  investment
company which  distributes  exempt-interest  dividends  during the year is
not  deductible.  Furthermore,  entities or persons  who are  "substantial
users"  (or  persons  related  to   "substantial   users")  of  facilities
financed by private  activity  bonds  should  consult  their tax  advisors
before  purchasing  shares of the Fund.  "Substantial  user" is  generally
defined as including a "nonexempt  person" who regularly  uses in trade or
business  a part of a  facility  financed  from the  proceeds  of  private
activity bonds.
         Investors  should  note that the Code may  require  investors  to
exclude  the  initial  sales  charge,  if  any,  paid on the  purchase  of
National  Municipal  shares  from the tax  basis of  those  shares  if the
shares are  exchanged  for shares of another  Calvert Group Fund within 90
days of  purchase.  This  requirement  applies only to the extent that the
payment of the original  sales  charge on the shares of the Series  causes
a reduction  in the sales  charge  otherwise  payable on the shares of the
Calvert  Group Fund  acquired in the  exchange,  and  investors  may treat
sales charges  excluded  from the basis of the original  sales as incurred
to acquire the new shares.
         National  Municipal  may  be  required  to  withhold  31%  of any
long-term  capital gain dividends and 31% of each  redemption  transaction
occurring in the Series if: (a) the  shareholder's  social security number
or other  taxpayer  identification  number  ("TIN") is not  provided or an
obviously  incorrect  TIN  is  provided;  (b)  the  shareholder  does  not
certify  under   penalties  of  perjury  that  the  TIN  provided  is  the
shareholder's  correct  TIN and that the  shareholder  is not  subject  to
backup  withholding  under  section  3406(a)(1)(C)  of the Code because of
underreporting  (however,  failure  to  provide  certification  as to  the
application   of  section   3406(a)(1)(C)   will  result  only  in  backup
withholding on capital gain  dividends,  not on  redemptions);  or (c) the
Fund is notified by the  Internal  Revenue  Service  that the TIN provided
by the shareholder is incorrect or that there has been  underreporting  of
interest or  dividends  by the  shareholder.  Affected  shareholders  will
receive statements at least annually specifying the amount withheld.
         In  addition,  the Series is required  to report to the  Internal
Revenue  Service the  following  information  with  respect to  redemption
transactions in National  Municipal:  (a) the shareholder's name, address,
account number and taxpayer  identification  number;  (b) the total dollar
value of the redemptions; and (c) the Series' identifying CUSIP number.
         Certain  shareholders  are,  however,   exempt  from  the  backup
withholding  and  broker  reporting   requirements.   Exempt  shareholders
include: corporations;  financial institutions;  tax-exempt organizations;
individual   retirement   plans;  the  U.S.,  a  State,  the  District  of
Columbia,  a U.S.  possession,  a  foreign  government,  an  international
organization,  or any political  subdivision,  agency, or  instrumentality
of  any  of the  foregoing;  U.S.  registered  commodities  or  securities
dealers;  real estate investment trusts;  registered investment companies;
bank common trust funds;  certain  charitable  trusts; and foreign central
banks of issue.  Nonresident  aliens  also are  generally  not  subject to
either  requirement  but,  along with  certain  foreign  partnerships  and
foreign  corporations,   may  instead  be  subject  to  withholding  under
section  1441 of the Code.  Shareholders  claiming  exemption  from backup
withholding  and  broker  reporting  should  call or  write  the  Fund for
further information.
    

==========================================================================
                           VALUATION OF SHARES
==========================================================================

         National  Municipal's  assets are valued  utilizing  the  average
bid  dealer  market  quotation  as  furnished  by an  independent  pricing
service.  Securities and other assets for which market  quotations are not
readily  available  are valued  based on the  current  market for  similar
securities or assets,  as  determined in good faith by the Fund's  Advisor
under the supervision of the Board of Directors.
         Valuations,   market   quotations  and  market   equivalents  are
provided by Kenny S&P Evaluation  Services,  a subsidiary of  McGraw-Hill.
The use of Kenny as a pricing  service  by the Fund has been  approved  by
the  Board of  Directors.  Valuations  provided  by Kenny  are  determined
without  exclusive  reliance on quoted prices and take into  consideration
appropriate  factors such as  institution-size  trading in similar  groups
of  securities,  yield,  quality,  coupon rate,  maturity,  type of issue,
trading characteristics, and other market data.
         National  Municipal  determines  the net  asset  value  for  each
class  of its  shares  every  business  day at the  close  of the  regular
session  of the New York  Stock  Exchange  (generally,  4:00 p.m.  Eastern
time),  and at such other times as may be  necessary or  appropriate.  The
Series does not  determine  net asset value on certain  national  holidays
or other days on which the New York Stock  Exchange is closed:  New Year's
Day, Presidents' Day, Good Friday,  Memorial Day,  Independence Day, Labor
Day, Thanksgiving Day and Christmas Day.

   
Net Asset Value and Offering Price Per Share
         Class A net asset value per share

==========================================================================
                  CALCULATION OF YIELD AND TOTAL RETURN
==========================================================================

         National  Municipal  may  advertise  its  "total  return."  Total
return  is  calculated   separately  for  each  class.   Total  return  is
historical in nature and is not intended to indicate  future  performance.
Total  return  will  be  quoted  for  the  most  recent  one-year  period,
five-year  period,  and period  from  inception  of  National  Municipal's
offering of shares.  Return  quotations  for periods in excess of one year
represent the average  annual total return for the period  included in the
particular   quotation.   Total  return  is  a  computation   of  National
Municipal's  dividend yield, plus or minus realized or unrealized  capital
appreciation or  depreciation,  less fees and expenses.  All Class A total
return quotations  reflect the deduction of National  Municipal's  maximum
sales charge  ("return with maximum load"),  except  quotations of "return
without maximum load" which do not deduct the sales charge.  Note:  "Total
Return"  as quoted in the  Financial  Highlights  section  of the  Series'
Prospectus   and  Annual  Report  to   Shareholders,   however,   per  SEC
instructions,  does  not  reflect  deduction  of  the  sales  charge,  and
corresponds  to  "return  without  maximum  load" as  referred  to herein.
Return without maximum load should be considered  only by investors,  such
as  participants  in certain  pension plans, to whom the sales charge does
not apply,  or for purposes of  comparison  only with  comparable  figures
which also do not reflect sales charges,  such as Lipper  averages.  Total
return is computed according to the following formula:

                             P(1 + T)n = ERV

   
where P = a hypothetical  initial payment of $1,000;  T = total return;  n
=  number  of  years;  and  ERV  =  the  ending   redeemable  value  of  a
hypothetical  $1,000  payment made at the beginning of the 1, 5 or 10 year
periods at the end of such periods (or portions  thereof,  if applicable).
Returns  for the one year  period  and  period  from  inception  (Class A,
September 30, 1992; Class C, March 1, 1994) are as follows:
    

   
                  Class A Shares        Class A Shares        Class C Shares
                  With Max. Load        W/O Max. Load
    

One Year          10.49%                13.64%                12.50%
From Inception     6.11%                 7.01%                 5.87%

         National  Municipal  may also  advertise its "yield" and "taxable
equivalent   yield."  As  with  total  return,   both  yield  figures  are
historical and are not intended to indicate  future  performance.  "Yield"
quotations  for each class of National  Municipal  refer to the  aggregate
imputed  yield-to-maturity  of each of the  Series'  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  reimbursement),  divided  by the
average  daily  number of  outstanding  shares for that class  entitled to
receive  dividends  times the  maximum  offering  price on the last day of
the  period  (so that the effect of the sales  charge is  included  in the
calculation),  compounded on a "bond  equivalent," or semi-annual,  basis.
Yield is computed according to the following formula:

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

where a = dividends and interest  earned  during the period;  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 maximum  offering  price per share on the
last day of the period.
         The taxable  equivalent  yield is the yield an investor  would be
required   to  obtain  from   taxable   investments   to  equal   National
Municipal's  yield,  all or a portion of which may be exempt from  federal
income taxes.  The taxable  equivalent yield is computed for each class by
taking the  portion of the yield  exempt  from  federal  income  taxes and
multiplying  the  exempt  yield by a factor  based on a stated  income tax
rate,  then  adding  the  portion  of the yield  that is not  exempt  from
federal  income  taxes.  The  factor  which is used to  calculate  the tax
equivalent  yield is the  reciprocal of the  difference  between 1 and the
applicable income tax rate, which will be stated in the advertisement.
         For the  thirty-day  period ended  December  31,  1995,  National
Municipal's  yield  for Class A shares  was  4.46% and its tax  equivalent
yield was 6.96% for an  investor in the 36%  federal  income tax  bracket,
and 6.85% for an investor in the 39.6%  federal  income tax  bracket.  For
the same period,  National  Municipal's yield for Class C shares was 3.63%
and  its  tax  equivalent  yield  was  5.67%  for an  investor  in the 36%
federal  income  tax  bracket,  and  6.03%  for an  investor  in the 39.6%
federal income tax bracket.

<F1> Officers and trustees deemed to be "interested persons" of the Fund
under the Investment Company Act of 1940, by virtue of their affiliation
with the Fund's Advisor.
         

   
Each  of  the  above  directors  and  officers  is a  trustee  or
officer  of  other  investment  companies  in the  Calvert  Group of Funds
except  Calvert  Social  Investment  Fund,  and Calvert World Values Fund,
Inc.,  of which only Messrs.  Baird,  Guffey,  Silby and Sorrell are among
the  trustees/directors;   Acacia  Capital  Corporation,   of  which  only
Messrs.  Blatz,  Diehl,  Pugh and  Sorrell  are among the  directors,  and
Calvert New World Fund,  Inc.,  of which only Messrs.  Sorrell and Martini
are among the  directors.  The address of directors and  officers,  unless
otherwise  noted,  is  4550  Montgomery  Avenue,  Suite  1000N,  Bethesda,
Maryland 20814.
         The Audit  Committee  of the Board of  Directors  is  composed of
Messrs.  Baird,  Blatz,  Feldman,  Guffey and Pugh. The Board's Investment
Policy  Committee is composed of Messrs.  Borts,  Diehl,  Gavian,  Rochat,
Silby and Sorrell.
         Directors  and  officers  of the Fund as a group own less than 1%
of Calvert National Municipal Intermediate Fund's outstanding shares.
         During  fiscal 1995,  directors of the Fund not  affiliated  with
the  Fund's   Advisor  were  paid  $4,073.   Directors  of  the  Fund  not
affiliated  with the  Advisor  currently  receive an annual fee of $20,250
for  service  as a  member  of  the  Board  of  Trustees/Directors  of the
Calvert  Group of Funds  plus a fee of $750 to $1200  for each  Board  and
Committee  meeting  attended;  such fees are allocated  among the Funds on
the basis of their net assets.
         Directors of the Series not affiliated  with the Series'  Advisor
may  elect to  defer  receipt  of all or a  percentage  of their  fees and
invest  them in any  fund in the  Calvert  Family  of  Funds  through  the
Directors/Trustees  Deferred  Compensation  Plan  (shown  as  "Pension  or
Retirement  Benefits Accrued as part of Fund Expenses,"  below).  Deferral
of the fees is designed to  maintain  the parties in the same  position as
if the fees were paid on a current  basis.  Management  believes this will
have a negligible  effect on the Fund's assets,  liabilities,  net assets,
and net income per share,  and will  ensure  that there is no  duplication
of advisory fees.

==========================================================================      
                                                                                
         The  Fund's  Investment   Advisor  is  Calvert  Asset  Management      
Company,  Inc., 4550 Montgomery Avenue,  Suite 1000N,  Bethesda,  Maryland     
20814, a subsidiary  of Calvert Group,  Ltd., which is a subsidiary  of Acacia 
Mutual  Life  Insurance Company  of Washington,   D.C.  ("Acacia Mutual").      
    
   
     The  Advisory  Contract  between  the Fund and the  Advisor  will
remain in effect  indefinitely,  provided continuance is approved at least
annually  by the vote of the  holders  of a  majority  of the  outstanding
shares  of  the  Fund,  or by  the  directors  of the  Fund;  and  further
provided that such  continuance  is also approved  annually by the vote of
a  majority  of the  directors  of the  Fund  who are not  parties  to the
Contract  or  interested  persons  of such  parties,  cast in  person at a
meeting  called for the purpose of voting on such  approval.  The Contract
may be  terminated  without  penalty  by  either  party on 60 days'  prior
written  notice;   it  automatically   terminates  in  the  event  of  its
assignment.
         Under the  Contract,  the  Advisor  manages  the  investment  and
reinvestment  of the Fun's  assets,  subject to the direction and control
of the Fund's Board of Directors.  For its services,  the Advisor receives
an annual fee of 0.60% of the first $500  million of the  Series'  average
daily net  assets,  0.50% of the next $500  million  of such  assets,  and
0.40% of all assets over $1 billion.
         The advisory  fee is payable  monthly.  The Advisor  reserves the
right  (i) to waive  all or a part of its fee and (ii) to  compensate,  at
its expense,  broker-dealers  in  consideration  of their  promotional and
administrative  services.  The Advisor may  recapture in later  years,  to
the extent  permitted  by law,  fees it waived or deferred and expenses it
paid in prior years.  Specifically,  the Advisor may recapture fees waived
or deferred and expenses  reimbursed  for the prior two-year  period,  but
in no event may it  recapture  fees or expenses  for any period later than
the two-year  period  ending  December  31,  1996.  Recapture is permitted
only to the extent it does not result in the Series's  aggregate  expenses
exceeding  an  annual  expense  limit of 2.00% of its  average  daily  net
assets.  The  advisory fee incurred in any given year will be paid in full
before  any  recapture  fees are paid for a prior  year.  Recaptured  fees
will  apply to the most  recent  suspension/reimbursement  period.  During
fiscal  year 1993,  the  Advisor  waived  advisory  fees of  $117,106  and
reimbursed  the Series  $89,240 for other  expenses.  During  fiscal 1994,
the Advisor  waived  advisory fees of $139,628 and  reimbursed  the Series
$20,701  for  other  expenses.  During  fiscal  year  1995,  the Fund paid
advisory fees of $270,912.
         The  Advisor  provides  the  Fund  with  investment   advice  and
research,  pays the  salaries  and  fees of all  directors  and  executive
officers of the Fund who are  principals of the Advisor,  and pays certain
Fund  advertising  and  promotional  expenses.  The Fund  pays  all  other
administrative  and  operating   expenses,   including:   custodial  fees;
shareholder  servicing,  dividend  disbursing  and  transfer  agency fees;
administrative  service fees;  federal and state  securities  registration
fees;  insurance  premiums;  trade association dues;  interest,  taxes and
other business fees;  legal and audit fees; and brokerage  commissions and
other  costs   associated   with  the   purchase  and  sale  of  portfolio
securities.
         The Advisor has agreed to reimburse  National  Municipal  for all
expenses,  excluding brokerage,  taxes,  interest, and extraordinary items
exceeding,  on a pro rata basis, the most restrictive  expense  limitation
in  those  states  which  the  Series'   shares  are  qualified  for  sale
(currently,  2.5% of the Series'  first $30 million of average net assets,
decreasing to 1.5% for assets over $100 million).
    

==========================================================================
                         ADMINISTRATIVE SERVICES
==========================================================================

         Calvert   Administrative   Services   Company,   a   wholly-owned
subsidiary  of  Calvert  Group,  Ltd.,  has been  retained  by the Fund to
provide certain  administrative  services  necessary to the conduct of the
Series'  affairs.  Such services  include the preparation of corporate and
regulatory  reports  and  filings,  portfolio  accounting,  and the  daily
determination  of net  investment  income  and net asset  value per share.
Calvert  Administrative  Services Company is entitled to receive an annual
fee of  0.10%  of the  Series'  average  net  assets  for  providing  such
services.  For the 1992 fiscal  period,  CASC  waived its entire fee.  The
fees paid by the Series to Calvert  Administrative  Services Company, Inc.
for  fiscal  years  1993,  1994,  and  1995  were  $19,672,  $45,876,  and
$45,152, respectively.

==========================================================================
                          METHOD OF DISTRIBUTION
==========================================================================

   
         The  Series  has  entered   into  an   agreement   with   Calvert
Distributors,  Inc. ("CDI"),  whereby CDI, acting as principal underwriter
for the Series,  makes a continuous  offering of the Series' securities on
a  "best   efforts"   basis.   Prior  to  April  1,  1995,  the  principal
underwriter was Calvert Securities  Corporation  ("CSC").  Under the terms
of the  agreement,  CDI  bears  all its  expenses  of  providing  services
pursuant  to the  agreement,  including  payment  of any  commissions  and
service  fees.  CDI  receives  all sales  charges  imposed on the  Series'
shares and compensates  broker-dealer  firms for sales of such shares (see
"Alternative  Sales  Options"  in  the  Prospectus).  CDI is  entitled  to
receive   reimbursement   of   distribution   expenses   pursuant  to  the
Distribution  Plans (see below).  For the fiscal periods  ending  December
31,  1993 and 1994,  CSC  received  sales  charges in excess of the dealer
reallowance  of $81,086 and  $37,135,  respectively.  During  fiscal 1995,
CDI received sales charges in excess of the dealer reallowance of $5,917.
         Pursuant to Rule 12b-1 under the  Investment  Company Act of 1940
("1940  Act"),  the Series has adopted  Distribution  Plans (the  "Plans")
which permit it to pay certain  expenses  associated with the distribution
of its shares.  Such expenses may not exceed,  on an annual  basis,  0.25%
of the Series' Class A average daily net assets.  No Class A  Distribution
Plan  expenses were paid in fiscal 1994.  Expenses  under the Class C Plan
may not exceed,  on an annual  basis,  0.80% of the Class C average  daily
net  assets.  The  Series'  Class  C  shares  paid  no  Distribution  Plan
expenses  in 1993,  since  those  shares were not offered to the public at
that  time.  During  fiscal  1994  and  1995,  the  Series  paid  Class  C
Distribution Plan expenses of $31,491 and $51,542, respectively.
         The  Plans  were  approved  by the  Board of  Directors/Trustees,
including the  Directors/Trustees  who are not "interested persons" of the
Funds  (as that  term is  defined  in the 1940 Act) and who have no direct
or indirect  financial  interest in the  operation  of the Plans or in any
agreements  related to the Plans.  The  selection  and  nomination  of the
Directors/Trustees   who  are  not  interested  persons  of  the  Fund  is
committed to the discretion of such disinterested  Directors/Trustees.  In
establishing  the  Plans,  the   Directors/Trustees   considered   various
factors    including   the   amount   of   the   distribution   fee.   The
Directors/Trustees  determined that there is a reasonable  likelihood that
the Plans will benefit the Funds and their shareholders.
         The  Plans  may  be  terminated  by  vote  of a  majority  of the
non-interested   Directors/Trustees   who  have  no  direct  or   indirect
financial  interest  in  the  Plans,  or by  vote  of a  majority  of  the
outstanding  shares of the Series and class.  Any change in the Plans that
would  materially  increase the  distribution  cost to the Series requires
approval of the shareholders of the affected class;  otherwise,  the Plans
may be  amended by the  Directors/Trustees,  including  a majority  of the
non-interested Directors/Trustees as described above.
         The Plans will  continue  in effect  successive  one-year  terms,
provided that such  continuance is  specifically  approved by (i) the vote
of a majority of the  Directors/Trustees  who are not parties to the Plans
or  interested  persons  of any  such  party  and who  have no  direct  or
indirect  financial  interest  in  the  Plans,  and  (ii)  the  vote  of a
majority of the entire Board of Directors/Trustees.
         Apart from the Plans,  the  Advisor,  at its  expense,  may incur
costs and pay expenses  associated with the  distribution of shares of the
Funds.
    

==========================================================================
                 TRANSFER AND SHAREHOLDER SERVICING AGENT
==========================================================================

         Calvert  Shareholder  Services,  Inc.,  a  subsidiary  of Calvert
Group,  Ltd., and Acacia  Mutual,  has been retained by the Fund to act as
transfer  agent,  dividend  disbursing  agent  and  shareholder  servicing
agent.   These   responsibilities   include:   responding  to  shareholder
inquiries  and  instructions  concerning  their  accounts;  crediting  and
debiting  shareholder  accounts  for  purchases  and  redemptions  of Fund
shares and  confirming  such  transactions;  daily updating of shareholder
accounts to reflect  declaration  and payment of dividends;  and preparing
and distributing  semi-annual  statements to shareholders  regarding their
accounts.   For  such  services,   Calvert  Shareholder  Services,   Inc.,
receives  compensation  based on the number of  shareholder  accounts  and
the  number  of  transactions.  The fees  paid by the  Series  to  Calvert
Shareholder  Services,  Inc. for the fiscal  periods 1993,  1994, and 1995
were $12,469, $25,149, and $ 30,243, respectively.

==========================================================================
                  INDEPENDENT ACCOUNTANTS AND CUSTODIANS
==========================================================================

   
         Coopers  and  Lybrand  L.L.P.  has been  selected by the Board of
Directors  to  serve as  independent  accountants  of the Fund for  fiscal
year 1996.  State Street Bank & Trust Company,  N.A., 225 Franklin Street,
Boston, MA 02110, serves as custodian of the Series's  investments.  First
National Bank of Maryland,  25 South Charles Street,  Baltimore,  Maryland
21203 acts as custodian of certain of the  Series's  cash assets.  Neither
custodian has any part in deciding the Fund's  investment  policies or the
choice of securities that are to be purchased or sold by the Series.
    

==========================================================================
                          PORTFOLIO TRANSACTIONS
==========================================================================

         Portfolio  transactions  are  undertaken  on the  basis  of their
desirability from an investment  standpoint.  Investment decisions and the
choice  of  brokers  and  dealers  are  made  by  the  Advisor  under  the
direction and supervision of the Board of Directors.
         Broker-dealers  who execute  portfolio  transactions on behalf of
the Fund are selected on the basis of their  professional  capability  and
the value and quality of their  services.  The Advisor  reserves the right
to place  orders for the  purchase or sale of  portfolio  securities  with
broker-dealers  who have sold shares of National  Municipal or who provide
it  with  statistical,   research,  or  other  information  and  services.
Although  any  statistical  research  or other  information  and  services
provided  by  broker-dealers  may be useful  to the  Advisor,  the  dollar
value of such  information and services is generally  indeterminable,  and
its  availability  or  receipt  does not serve to  materially  reduce  the
Advisor's   normal   research   activities   or  expenses.   No  brokerage
commissions  have been paid to any  officer or director of the Fund or any
of their affiliates,  or broker-dealers  for the period ended December 31,
1993, 1994, or 1995.
         The  Advisor  may also  execute  portfolio  transactions  with or
through  broker-dealers  who  have  sold  shares  of  National  Municipal.
However,  such sales will not be a qualifying or  disqualifying  factor in
a  broker-dealer's  selection nor will the selection of any  broker-dealer
be based on the volume of shares sold.  The Advisor or its  affiliate  may
compensate,  at its  expense,  broker-dealers  in  consideration  of their
promotional and administrative services.
         The  portfolio  turnover  was 162%,  122%,  and 57% for the 1993,
1994, and 1995 fiscal years, respectively.

==========================================================================
                           GENERAL INFORMATION
==========================================================================

         The  Fund  was  organized  as a  corporation  under  the  General
Corporation  Law of the State of Maryland on February 4, 1992.  The Fund's
other  series  are:  Calvert  California   Municipal   Intermediate  Fund,
Calvert Arizona Municipal  Intermediate  Fund,  Calvert Maryland Municipal
Intermediate Fund,  Calvert Michigan Municipal  Intermediate Fund, Calvert
New York  Municipal  Intermediate  Fund,  Calvert  Pennsylvania  Municipal
Intermediate  Fund,  and Calvert  Virginia  Municipal  Intermediate  Fund.
Prior to March 1, 1994, Calvert National  Municipal  Intermediate Fund was
known as Calvert Intermediate Municipal Fund.
         National   Municipal   will  send  its   shareholders   unaudited
semi-annual  and audited  annual reports that will include the Series' net
asset value per share,  portfolio  securities,  income and  expenses,  and
other financial information.
         Each  share  of the  Series  represents  an  equal  proportionate
interest  in that  Series  with each other  share and is  entitled to such
dividends and  distributions  out of the income belonging to the Series as
declared by the Board.  The Series offers two separate  classes of shares:
Class  A and  Class  C.  Each  class  represents  interests  in  the  same
portfolio of  investments  but, as further  described  in the  Prospectus,
each class is subject to  differing  sales  charges  and  expenses,  which
will result in  differing  net asset  values and  distributions.  Upon any
liquidation  of the  Series,  shareholders  of each class are  entitled to
share pro rata in the net assets available for distribution.

==========================================================================

Municipal Obligations
         Municipal  obligations  are debt  obligations  issued by  states,
cities,  municipalities,  and their  agencies to obtain  funds for various
public  purposes.  Such purposes  include the construction of a wide range
of public  facilities,  the  refunding  of  outstanding  obligations,  the
obtaining  of funds for  general  operating  expenses,  and the lending of
funds to other public  institutions and facilities.  In addition,  certain
types of  industrial  development  bonds  are  issued  by or on  behalf of
public  authorities  to obtain  funds for many  types of local,  privately
operated  facilities.  Such  debt  instruments  are  considered  municipal
obligations  if the interest  paid on them is exempt from  federal  income
tax in the opinion of bond  counsel to the issuer.  Although  the interest
paid  on  the  proceeds   from  private   activity   bonds  used  for  the
construction,  equipment,  repair or  improvement  of  privately  operated
industrial  or  commercial  facilities  may be exempt from federal  income
tax,  current federal tax law places  substantial  limitations on the size
of such issues.
         Municipal   obligations   are  generally   classified  as  either
"general  obligation" or "revenue"  bonds.  General  obligation bonds are
secured by the issuer's  pledge of its faith,  credit and taxing power for
the payment of  principal  and  interest.  Revenue  bonds are payable from
the revenues  derived from a  particular  facility or class of  facilities
or, in some  cases,  from the  proceeds  of a special  excise tax or other
specific   revenue  source,   but  not  from  the  general  taxing  power.
Tax-exempt  industrial  development  bonds are in most cases revenue bonds
and do not  generally  carry  the  pledge  of the  credit  of the  issuing
municipality.  There  are,  of  course,  variations  in  the  security  of
municipal obligations,  both within a particular  classification and among
classifications.
         Municipal  obligations  are  generally  traded  on the basis of a
quoted  yield to  maturity,  and the price of the  security is adjusted so
that  relative  to the stated  rate of  interest it will return the quoted
rate to the purchaser.
         Short-term and  limited-term  municipal  obligations  include Tax
Anticipation Notes,  Revenue  Anticipation Notes, Bond Anticipation Notes,
Construction  Loan Notes,  and Discount  Notes.  The  maturities  of these
instruments  at the time of  issue  generally  will  range  between  three
months and one year.  Pre-Refunded  Bonds with longer  nominal  maturities
that are due to be retired  with the  proceeds of an  escrowed  subsequent
issue  at a  date  within  one  year  and  three  years  of  the  time  of
acquisition  are also  considered  short-term and  limited-term  municipal
obligations.

Municipal Bond and Note Ratings
Description  of Moody's  Investors  Service,  Inc.'s  ratings of state and
municipal notes:
         Moody's   ratings  for  state  and  municipal   notes  and  other
short-term  obligations are designated  Moody's  Investment Grade ("MIG").
This distinction is in recognition of the differences  between  short-term
credit risk and long-term risk.
         MIG 1: Notes  bearing this  designation  are of the best quality,
enjoying  strong  protection  from  established  cash  flows of funds  for
their servicing or from  established and broad-based  access to the market
for refinancing, or both.
         MIG2:  Notes bearing this  designation are of high quality,  with
margins of  protection  ample  although  not so large as in the  preceding
group.
         MIG3:  Notes bearing this  designation are of favorable  quality,
with all  security  elements  accounted  for but  lacking  the  undeniable
strength  of the  preceding  grades.  Market  access for  refinancing,  in
particular, is likely to be less well established.
         MIG4:  Notes bearing this  designation  are of adequate  quality,
carrying  specific  risk  but  having  protection   commonly  regarded  as
required of an investment  security and not  distinctly  or  predominantly
speculative.

Description  of  Moody's  Investors   Service   Inc.'s/Standard  &  Poor's
municipal bond ratings:
         Aaa/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.  This  rating  indicates  an  extremely  strong
capacity to pay principal and interest.
         Aa/AA:   Bonds  rated  AA  also  qualify  as  high-quality   debt
obligations.  Capacity to pay principal  and interest is very strong,  and
in the  majority  of  instances  they differ from AAA issues only in small
degree.  They are rated  lower  than the best  bonds  because  margins  of
protection  may  not be as  large  as in Aaa  securities,  fluctuation  of
protective  elements  may be of greater  amplitude,  or there may be other
elements  present which make long-term  risks appear  somewhat larger than
in Aaa securities.
         A/A:  Upper-medium grade obligations.  Factors giving security to
principal  and  interest  are  considered  adequate,  but  elements may be
present  which make the bond  somewhat  more  susceptible  to the  adverse
effects of circumstances and economic conditions.
         Baa/BBB:  Medium  grade  obligations;  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.
         Ba/BB,  B/B,  Caa/CCC,  Ca/CC:  Debt rated in these categories is
regarded  as  predominantly  speculative  with  respect to capacity to pay
interest and repay principal.  There may be some large  uncertainties  and
major  risk  exposure  to  adverse  conditions.  The  higher the degree of
speculation, the lower the rating.
         C/C: This rating is only for no-interest income bonds.
         D: Debt in default;  payment of interest  and/or  principal is in
arrears.

                                                                        

                                                                     
                             LETTER OF INTENT

Ladies and Gentlemen:

         By signing this Letter of Intent, or affirmatively marking the
Letter of Intent option on my Fund Account Application Form, I agree to
be bound by the terms and conditions applicable to Letters of Intent
appearing in the Prospectus and the Statement of Additional Information
for the Fund and the provisions described below as they may be amended
from time to time by the Fund. Such amendments will apply automatically
to existing Letters of Intent.

         I intend to invest in the shares of:  (Fund or Portfolio name<F4>*)
during the thirteen (13) month period from the date of my first purchase 
pursuant to this Letter (which cannot be more than ninety (90) days prior to 
the date of this Letter or my Fund Account Application Form, whichever is
applicable), an aggregate amount (excluding any reinvestments of distributions)
of at least fifty thousand dollars ($50,000) which, together with my current 
holdings of the Fund (at public offering price on date of this Letter or my 
Fund Account Application Form, whichever is applicable), will equal or exceed
the amount checked below:

<F4> *"Fund" in this Letter of Intent shall refer to the Fund or Portfolio,
as the case may be, here indicated.


         __ $50,000 __ $100,000 __ $250,000 __ $500,000 __ $1,000,000

         Subject to the conditions specified below, including the terms
of escrow, to which I hereby agree, each purchase occurring after the
date of this Letter will be made at the public offering price applicable
to a single transaction of the dollar amount specified above, as
described in the Fund's prospectus. No portion of the sales charge
imposed on purchases made prior to the date of this Letter will be
refunded.

         I am making no commitment to purchase shares, but if my
purchases within thirteen months from the date of my first purchase do
not aggregate the minimum amount specified above, I will pay the
increased amount of sales charges prescribed in the terms of escrow
described below. I understand that 4.75% of the minimum dollar amount
specified above will be held in escrow in the form of shares (computed
to the nearest full share). These shares will be held subject to the
terms of escrow described below.

         From the initial purchase (or subsequent purchases if
necessary), 4.75% of the dollar amount specified in this Letter shall be
held in escrow in shares of the Fund by the Fund's transfer agent. For
example, if the minimum amount specified under the Letter is $50,000,
the escrow shall be shares valued in the amount of $2,375 (computed at
the public offering price adjusted for a $50,000 purchase). All
dividends and any capital gains distribution on the escrowed shares will
be credited to my account.

         If the total minimum investment specified under the Letter is
completed within a thirteen month period, escrowed shares will be
promptly released to me. However, shares disposed of prior to completion
of the purchase requirement under the Letter will be deducted from the
amount required to complete the investment commitment.

         Upon expiration of this Letter, the total purchases pursuant to
the Letter are less than the amount specified in the Letter as the
intended aggregate purchases, Calvert Distributors, Inc. ("CDI") will
bill me for an amount equal to the difference between the lower load I
paid and the dollar amount of sales charges which I would have paid if
the total amount purchased had been made at a single time. If not paid
by the investor within 20 days, CDI will debit the difference from my
account. Full shares, if any, remaining in escrow after the
aforementioned adjustment will be released and, upon request, remitted
to me.

         I irrevocably constitute and appoint CDI as my
attorney-in-fact, with full power of substitution, to surrender for
redemption any or all escrowed shares on the books of the Fund. This
power of attorney is coupled with an interest.

         The commission allowed by Calvert Distributors, Inc. to the
broker-dealer named herein shall be at the rate applicable to the
minimum amount of my specified intended purchases.

         The Letter may be revised upward by me at any time during the
thirteen-month period, and such a revision will be treated as a new
Letter, except that the thirteen-month period during which the purchase
must be made will remain unchanged and there will be no retroactive
reduction of the sales charges paid on prior purchases.

         In determining the total amount of purchases made hereunder,
shares disposed of prior to termination of this Letter will be deducted.
My broker-dealer shall refer to this Letter of Intent in placing any
future purchase orders for me while this Letter is in effect.

==========================================================================
                           INVESTMENT OBJECTIVE
==========================================================================

         The  Calvert  Municipal  Intermediate  Funds  ("Funds" or "Fund")
are designed to provide  individual and  institutional  investors with the
highest level of interest  income  exempt from federal and specific  state
income  taxes  as  is  consistent  with  prudent  investment   management,
preservation of capital,  and the quality and maturity  characteristics of
the  Fund.  There is,  of  course,  no  assurance  that the Funds  will be
successful  in meeting  their  investment  objectives;  there are inherent
risks in the ownership of any investment.
         Dividends  paid by the Funds will  fluctuate  with income  earned
on  investments.  In addition,  dividends and  distributions  paid and the
value of each share will vary by class of shares:  the share  values  will
fluctuate  to reflect  changes in the market  value of  investments.  Each
Fund will attempt,  through careful management,  to reduce these risks and
enhance the opportunities for higher income and greater price stability.

==========================================================================
                           INVESTMENT POLICIES
==========================================================================

         Each Fund  invests  primarily  in a  nondiversified  portfolio of
municipal  obligations,  including  some with interest that may be subject
to   alternative   minimum  tax.  A  complete   explanation  of  municipal
obligations and municipal bond and note ratings appears in the Appendix.
         Under  normal  market  conditions,  each  Fund  will  attempt  to
invest at least 65% of its total  assets  in  municipal  obligations  with
interest  that is exempt  from  federal  and  specific  state  income tax,
including  those  issued  by or on  behalf of the state for which the Fund
is named  and the  state's  political  subdivisions.  Each  Fund will also
attempt  to  invest  the  remaining  35%  of its  total  assets  in  these
obligations,  but may invest it in municipal  obligations of other states,
territories  and  possessions  of  the  United  States,  the  District  of
Columbia, and their respective  authorities,  agencies,  instrumentalities
and political  subdivisions.  Dividends you receive from the Fund that are
derived from  interest on  tax-exempt  obligations  of other  governmental
issuers  will be exempt from  federal  income tax,  but will be subject to
state income taxes.

Variable Rate Demand Notes
         The Boards of  Directors/Trustees  have approved  investments  in
floating and variable  rate demand  notes upon the  following  conditions:
each Fund has right of  demand,  upon  notice not to exceed  thirty  days,
against  the issuer to receive  payment;  the issuer  will be able to make
payment  upon such  demand,  either from its own  resources  or through an
unqualified  commitment  from a  third  party;  and the  rate of  interest
payable is  calculated  to ensure that the market value of such notes will
approximate par value on the adjustment  dates. The remaining  maturity of
such demand  notes is deemed the period  remaining  until such time as the
Fund has the right to dispose of the notes at a price  which  approximates
par and market value.  Notes with a right of demand  exceeding  seven days
are considered illiquid and are subject to purchase restrictions.

Municipal Leases
         The  Funds  may  invest  in  municipal   leases,   or  structured
instruments  where  the  underlying  security  is  a  municipal  lease.  A
municipal   lease  is  an  obligation  of  a  government  or  governmental
authority,  not  subject  to  voter  approval,  used  to  finance  capital
projects or equipment  acquisitions  and payable  through  periodic rental
payments.  The Funds may  purchase  unrated  leases.  The Funds'  Advisor,
under  the   supervision   of  the   Boards  of   Directors/Trustees,   is
responsible  for  determining  the  credit  quality  of such  leases on an
ongoing basis,  including an assessment of the  likelihood  that the lease
will  not  be  canceled.   Certain  municipal  leases  may  be  considered
illiquid  and  subject  to a Fund's  limit  on  illiquid  securities.  The
Boards  of  Directors/Trustees  have  directed  the  Advisor  to  treat  a
municipal  lease  as a  liquid  security  if it  satisfies  the  following
conditions:  (A)  such  treatment  must  be  consistent  with  the  Fund's
investment  restrictions;  (B) the Advisor should be able to conclude that
the  obligation  will  maintain its  liquidity  throughout  the time it is
held by the Fund,  based on the following  factors:  (1) whether the lease
may be  terminated  by the lessee;  (2) the  potential  recovery,  if any,
from a sale of the leased  property  upon  termination  of the lease;  (3)
the lessee's  general credit  strength  (e.g.,  its debt,  administrative,
economic  and   financial   characteristics   and   prospects);   (4)  the
likelihood  that the lessee  will  discontinue  appropriating  funding for
the leased  property  because the property is no longer  deemed  essential
to   its   operations    (e.g.,   the   potential   for   an   "event   of
nonappropriation"),  and (5) any  credit  enhancement  or  legal  recourse
provided upon an event of  nonappropriation  or other  termination  of the
lease;  (C) the Advisor  should  determine  whether the  obligation can be
disposed  of within  seven  days in the  ordinary  course of  business  at
approximately  the amount at which the Fund has valued it for  purposes of
calculating   the  Fund's  net  asset  value,   taking  into  account  the
following  factors:  (1) the  frequency  of  trades  and  quotes;  (2) the
volatility  of  quotations  and trade  prices;  (3) the  number of dealers
willing to  purchase  or sell the  security  and the  number of  potential
purchasers;  (4)  dealer  undertakings  to make a market in the  security;
(5) the nature of the  security and the nature of the  marketplace  trades
(e.g.,  the  time  needed  to  dispose  of the  security,  the  method  of
soliciting offers,  and the mechanics of the transfer);  (6) the rating of
the  security and the  financial  condition  and  prospects of the issuer;
and (7) other  factors  relevant  to the Fund's  ability to dispose of the
security;  and (D) the Advisor should have  reasonable  expectations  that
the municipal  lease  obligation  will  maintain its liquidity  throughout
the time the instrument is held by the Fund.

Temporary Investments
         Short-term   money   market   type   investments    consist   of:
obligations of the U.S.  Government,  its agencies and  instrumentalities;
certificates  of deposit of banks with  assets of one  billion  dollars or
more;  commercial  paper or other  corporate  notes  of  investment  grade
quality;   and  any  of  such  items  subject  to  short-term   repurchase
agreements.

When-Issued Purchases
         Securities  purchased on a when-issued  basis and the  securities
held in a Fund's  portfolio  are subject to changes in market  value based
on the  public's  perception  of the  creditworthiness  of the  issuer and
changes in the level of interest  rates  (which will  generally  result in
both  changing  in  value  in  the  same  way,  i.e.,  both   experiencing
appreciation  when interest rates decline and  depreciation  when interest
rates rise).  Therefore,  if in order to achieve higher  interest  income,
the Funds  remain  substantially  fully  invested at the same time that it
has purchased  securities on a when-issued  basis, there will be a greater
possibility  that the  market  value  of their  assets  may  vary.  No new
when-issued  commitments  will be made if more  than 50% of a  Fund's  net
assets would become so committed.
         The Funds  will meet  their  obligations  to pay for  when-issued
securities  from  then-  available  cash  flow,  sale  of  securities  or,
although  the Funds would not  normally  expect to do so, from sale of the
when-issued  securities  themselves (which may have a market value greater
or less than the Fund's  payment  obligation).  Sale of securities to meet
such obligations  carries with it a greater  potential for the realization
of capital  losses and capital  gains  which are not exempt  from  federal
income tax.

Transactions in Futures Contracts
         The  Funds  may  engage  in the  purchase  and  sale  of  futures
contracts on an index of municipal bonds or on U.S.  Treasury  securities,
or options on such futures  contracts,  for hedging  purposes only. A Fund
may sell such futures  contracts in  anticipation of a decline in the cost
of  municipal  bonds it holds or may purchase  such  futures  contracts in
anticipation  of an  increase  in the  value of  municipal  bonds the Fund
intends to acquire.  The Funds also are  authorized  to purchase  and sell
other financial  futures  contracts which in the opinion of the Investment
Advisor  provide  an  appropriate  hedge  for  some  or all of the  Funds'
securities.
         Because of low initial  margin  deposits made upon the opening of
a futures position,  futures  transactions  involve substantial  leverage.
As a  result,  relatively  small  movements  in the  price of the  futures
contract can result in  substantial  unrealized  gains or losses.  Because
the  Funds  will  engage in the  purchase  and sale of  financial  futures
contracts  solely for hedging  purposes,  however,  any losses incurred in
connection  therewith  should,  if the hedging strategy is successful,  be
offset in whole or in part by  increases in the value of  securities  held
by a Fund or  decreases  in the price of  securities  the Fund  intends to
acquire.
         Municipal  bond  index  futures  contracts  commenced  trading in
June 1985,  and it is  possible  that  trading in such  futures  contracts
will be less liquid than that in other futures  contracts.  The trading of
futures  contracts  and  options  thereon is  subject  to  certain  market
risks,  such as trading  halts,  suspensions,  exchange or clearing  house
equipment  failures,  government  intervention  or  other  disruptions  of
normal  trading  activity,  which  could at  times  make it  difficult  or
impossible to liquidate existing positions.
         The liquidity of a secondary  market in futures  contracts may be
further   adversely   affected  by  "daily   price   fluctuation   limits"
established  by contract  markets,  which limit the amount of  fluctuation
in the  price of a futures  contract  or  option  thereon  during a single
trading  day.  Once the daily limit has been reached in the  contract,  no
trades may be entered  into at a price beyond the limit,  thus  preventing
the  liquidation of open positions.  Prices of existing  contracts have in
the past moved the daily limit on a number of  consecutive  trading  days.
A Fund will  enter into a futures  position  only if, in the  judgment  of
the Investment  Advisor,  there appears to be an actively traded secondary
market for such futures contracts.
         The  successful  use of  transactions  in futures  contracts  and
options  thereon  depends  on the  ability  of the  Investment  Advisor to
correctly  forecast the direction  and extent of price  movements of these
instruments,  as well as price  movements of the securities held by a Fund
within a given  time  frame.  To the extent  these  prices  remain  stable
during  the  period in which a futures  or  option  contract  is held by a
Fund,  or move in a  direction  opposite to that  anticipated,  a Fund may
realize  a  loss  on  the  hedging  transaction  which  is  not  fully  or
partially  offset by an  increase  in the value of the Fund's  securities.
As a result,  the Fund's  total return for such period may be less than if
it had not engaged in the hedging transaction.

Description of Financial Futures Contracts
         Futures  Contracts.  A futures contract obligates the seller of a
contract to deliver and the  purchaser  of a contract to take  delivery of
the type of  financial  instrument  called for in the contract or, in some
instances,  to make a cash  settlement,  at a specified  future time for a
specified  price.  Although  the  terms  of a  contract  call  for  actual
delivery or acceptance of securities,  or for a cash  settlement,  in most
cases the  contracts  are closed out before the delivery  date without the
delivery or  acceptance  taking  place.  The Funds intend to close out any
futures contracts prior to the delivery date of such contracts.
         A Fund may sell futures  contracts in  anticipation  of a decline
in the value of its  investments in municipal  bonds.  The loss associated
with any such  decline  could be reduced  without  employing  futures as a
hedge  by  selling  long-term   securities  and  either   reinvesting  the
proceeds in securities  with shorter  maturities  or by holding  assets in
cash. This strategy,  however,  entails increased transaction costs in the
form of  brokerage  commissions  and  dealer  spreads  and will  typically
reduce  the  Fund's  average  yields  as a  result  of the  shortening  of
maturities.
         The  purchase  or sale of a  futures  contract  differs  from the
purchase  or sale of a  security,  in that no price or  premium is paid or
received.  Instead,  an amount  of cash or  securities  acceptable  to the
Fund's  futures  commission  merchant  and the relevant  contract  market,
which  varies but is generally  about 5% or less of the  contract  amount,
must be  deposited  with the  broker.  This  amount  is known as  "initial
margin," and  represents a "good faith" deposit  assuring the  performance
of  both  the  purchaser  and  the  seller  under  the  futures  contract.
Subsequent  payments to and from the broker,  known as "variation margin,"
are  required  to be made on a daily  basis as the  price  of the  futures
contract  fluctuates,  making the long or short  positions  in the futures
contract  more or less  valuable,  a  process  known  as  "marking  to the
market."  Prior  to the  settlement  date  of the  futures  contract,  the
position  may be closed  out by taking an  opposite  position  which  will
operate  to  terminate  the  position  in the  futures  contract.  A final
determination  of  variation  margin  is  then  made,  additional  cash is
required  to be paid  to or  released  by the  broker,  and the  purchaser
realizes  a loss  or  gain.  In  addition,  a  commission  is paid on each
completed purchase and sale transaction.
         
     The sale of financial futures  contracts  provides an alternative
means of hedging a Fund against  declines in the value of its  investments
in  municipal  bonds.  As such  values  decline,  the value of the  Fund's
position in the futures  contracts will tend to increase,  thus offsetting
all or a portion of the  depreciation  in the  market  value of the Fund's
fixed income  investments which are being hedged.  While a Fund will incur
commission  expenses in  establishing  and closing out futures  positions,
commissions  on  futures  transactions  may be  significantly  lower  than
transaction  costs  incurred  in the  purchase  and sale of  fixed  income
securities.   In  addition,  the  ability  of  a  Fund  to  trade  in  the
standardized  contracts  available in the futures  market may offer a more
effective  hedging  strategy than a program to reduce the average maturing
of  portfolio  securities,  due  to  the  unique  and  varied  credit  and
technical  characteristics of the municipal debt instruments  available to
the Fund.  Employing  futures as a hedge may also  permit a Fund to assume
a hedging posture without  reducing the yield on its  investments,  beyond
any amounts required to engage in futures trading.
         
     The  Funds  may  engage  in the  purchase  and  sale  of  futures
contracts on an index of municipal  securities.  These instruments provide
for the purchase or sale of a  hypothetical  portfolio of municipal  bonds
at a fixed price in a stated  delivery  month.  Unlike most other  futures
contracts,  however,  a municipal  bond index  futures  contract  does not
require  actual  delivery of securities  but results in a cash  settlement
based  upon the  difference  in value of the  index  between  the time the
contract was entered into and the time it is liquidated.
         
     The  municipal  bond  index  underlying  the  futures   contracts
traded  by  the  Portfolio  is  The  Bond  Buyer   Municipal  Bond  Index,
developed by The Bond Buyer and the Chicago  Board of Trade  ("CBT"),  the
contract  market on which the futures  contracts are traded.  As currently
structured,  the  index  is  comprised  of 40  tax-exempt  term  municipal
revenue  and general  obligation  bonds.  Each bond  included in the index
must be rated  either A- or higher by  Standard & Poor's or A or higher by
Moody's Investors  Service and must have a remaining  maturity of 19 years
or  more.   Twice  a  month  new   issues   satisfying   the   eligibility
requirements  are added to,  and an equal  number  of old  issues  will be
deleted  from,  the  index.  The  value  of the  index is  computed  daily
according  to a formula  based  upon the price of each bond in the  index,
as evaluated by four dealer-to-dealers brokers.
         
     The Funds may also  purchase and sell  futures  contracts on U.S.
Treasury  bills,  notes and bonds for the same types of hedging  purposes.
Such futures  contracts  provide for delivery of the  underlying  security
at a  specified  future  time  for a fixed  price,  and the  value  of the
futures  contract  therefore   generally   fluctuates  with  movements  in
interest rates.
         
     The municipal bond index futures  contract,  futures contracts on
U.S.  Treasury  securities  and  options  on such  futures  contracts  are
traded  on the CBT,  which,  like  other  contract  markets,  assures  the
performance  of the parties to each  futures  contract  through a clearing
corporation,   a   nonprofit   organization   managed   by  the   exchange
membership,  which is also  responsible  for handling daily  accounting of
deposits or withdrawals of margin.
         The Funds may also  purchase  financial  futures  contracts  when
not fully invested in municipal  bonds,  in anticipation of an increase in
the cost of  securities  a Fund intends to  purchase.  As such  securities
are purchased,  an equivalent  amount of futures  contracts will be closed
out.  In a  substantial  majority  of  these  transactions,  a  Fund  will
purchase  municipal bonds upon termination of the futures  contracts.  Due
to changing  market  conditions and interest rate  forecasts,  however,  a
futures  position may be terminated  without a  corresponding  purchase of
securities.  Nevertheless,  all  purchases of futures  contracts by a Fund
will be subject to certain restrictions, described below.
         Options on  Futures  Contracts.  An option on a futures  contract
provides the purchaser with the right,  but not the  obligation,  to enter
into  a long  position  in  the  underlying  futures  contract  (that  is,
purchase  the  futures  contract),  in the case of a "call"  option,  or a
short  position  (sell  the  futures  contract),  in the  case  of a "put"
option,  for a fixed price up to a stated  expiration  date. The option is
purchased  for  a  non-refundable   fee,  known  as  the  "premium."  Upon
exercise of the option,  the contract  market  clearing house assigns each
party  to the  option  an  opposite  position  in the  underlying  futures
contract.  In the event of  exercise,  therefore,  the parties are subject
to all of the risks of futures  trading,  such as  payment of initial  and
variation margin.  In addition,  the seller, or "writer," of the option is
subject  to  margin  requirements  on  the  option  position.  Options  on
futures  contracts  are  traded  on  the  same  contract  markets  as  the
underlying futures contracts.
         The Funds may  purchase  options  on  futures  contracts  for the
same  types  of  hedging  purposes  described  above  in  connection  with
futures   contracts.   For  example,   in  order  to  protect  against  an
anticipated  decline  in the value of  securities  it holds,  a Fund could
purchase  put  options  on  futures  contracts,  instead  of  selling  the
underlying  futures  contracts.  Conversely,  in order to protect  against
the adverse  effects of  anticipated  increases in the costs of securities
to be acquired,  a Fund could purchase call options on futures  contracts,
instead  of  purchasing  the  underlying  futures  contracts.   The  Funds
generally  will sell  options  on futures  contracts  only to close out an
existing position.
         The Funds will not  engage in  transactions  in such  instruments
unless  and  until  the   Investment   Advisor   determines   that  market
conditions  and the  circumstances  of the Fund warrant such  trading.  To
the extent a Fund engages in the  purchase  and sale of futures  contracts
or options  thereon,  it will do so only at a level which is reflective of
the  Investment  Advisor's  view  of the  hedging  needs  of a  Fund,  the
liquidity  of  the  market  for  futures  contracts  and  the  anticipated
correlation  between  movements  in the  value of the  futures  or  option
contract and the value of securities held by the Portfolio.
         Restrictions  on the Use of  Futures  Contracts  and  Options  on
Futures  Contracts.  Under  regulations of the Commodity  Futures  Trading
Commission  ("CFTC"),  the futures  trading  activities  described  herein
will not  result  in a Fund  being  deemed  to be a  "commodity  pool," as
defined   under  such   regulations,   provided   that   certain   trading
restrictions  are  adhered to. In  particular,  CFTC  regulations  require
that all futures and option  positions  entered  into by a Fund qualify as
bona fide hedge  transactions,  as defined under CFTC regulations,  or, in
the case of long  positions,  that the value of such  positions not exceed
an amount of  segregated  funds  determined  by  reference to certain cash
and  securities  positions  maintained  by a Fund and  accrued  profits on
such  positions.  In  addition,  a Fund may not  purchase or sell any such
instruments if, immediately  thereafter,  the sum of the amount of initial
margin deposits on the Fund's existing  futures  positions would exceed 5%
of the market value of its net assets.
         When a Fund  purchases a futures  contract,  it will  maintain an
amount  of cash,  cash  equivalents  (for  example,  commercial  paper and
daily  tender  adjustable  notes) or  short-term  high-grade  fixed income
securities  in a  segregated  account with the Fund's  custodian,  so that
the amount so segregated  plus the amount of initial and variation  margin
held in the account of its broker  equals the market  value of the futures
contract, thereby ensuring that the use of such futures is unleveraged.
         Risk  Factors  in   Transactions   in  Futures   Contracts.   The
particular  municipal bonds  comprising the index underlying the municipal
bond index  futures  contract  may vary from the bonds held by a Fund.  In
addition,  the securities  underlying  futures  contracts on U.S. Treasury
securities  will  not be the same as  securities  held by the  Fund.  As a
result,  a Fund's  ability  effectively  to hedge all or a portion  of the
value of its  municipal  bonds through the use of futures  contracts  will
depend  in part on the  degree  to  which  price  movements  in the  index
underlying  the  municipal  bond  index  futures  contract,  or  the  U.S.
Treasury  securities  underlying other futures contracts trade,  correlate
with price movements of the municipal bonds held by the Fund.
         For  example,  where prices of  securities  in a Fund do not move
in the  same  direction  or to  the  same  extent  as  the  values  of the
securities  or index  underlying a futures  contract,  the trading of such
futures  contracts may not  effectively  hedge the Fund's  investments and
may  result  in  trading  losses.  The  correlation  may  be  affected  by
disparities  in  the  average  maturity,  ratings,   geographical  mix  or
structure of the Fund's  investments  as compared to those  comprising the
index,  and general  economic  or  political  factors.  In  addition,  the
correlation  between  movements  in the  value of the index  underlying  a
futures  contract may be subject to change over time,  as additions to and
deletions  from the index  alter  its  structure.  In the case of  futures
contracts  on  U.S.   Treasury   securities  and  options   thereon,   the
anticipated  correlation  of price  movements  between  the U.S.  Treasury
securities  underlying  the futures or options and municipal  bonds may be
adversely   affected  by  economic,   political,   legislative   or  other
developments  that have a disparate  impact on the respective  markets for
such securities.  In the event that the Investment  Advisor  determines to
enter into  transactions  in financial  futures  contracts  other than the
municipal  bond  index  futures  contract  or  futures  on  U.S.  Treasury
securities,  the risk of imperfect  correlation  between  movements in the
prices of such futures  contracts  and the prices of municipal  bonds held
by a Fund may be greater.
         The  trading of futures  contracts  on an index also  entails the
risk of  imperfect  correlation  between  movements  in the  price  of the
futures  contract and the value of the underlying  index.  The anticipated
spread  between  the prices may be  distorted  due to  differences  in the
nature of the  markets,  such as margin  requirements,  liquidity  and the
participation  of  speculators  in  the  futures  markets.   The  risk  of
imperfect  correlation,  however,  generally  diminishes  as the  delivery
month specified in the futures contract approaches.
         Prior  to   exercise  or   expiration,   a  position  in  futures
contracts or options  thereon may be  terminated  only by entering  into a
closing  purchase or sale  transaction.  This requires a secondary  market
on the relevant  contract  market.  The Funds will enter into a futures or
option  position  only if there  appears to be a liquid  secondary  market
therefor,   although  there  can  be  no  assurance  that  such  a  liquid
secondary  market will exist for any  particular  contract at any specific
time.  Thus,  it may not be possible  to close out a position  once it has
been established.  Under such  circumstances,  a Fund could be required to
make  continuing  daily cash payments of variation  margin in the event of
adverse price  movements.  In such situation,  if a Fund has  insufficient
cash,  it may be  required  to sell  portfolio  securities  to meet  daily
variation  margin  requirements  at a time when it may be  disadvantageous
to do so. In addition,  a Fund may be required to perform  under the terms
of the futures or option  contracts it holds.  The  inability to close out
futures or  options  positions  also  could have an adverse  impact on the
Fund's ability effectively to hedge its portfolio.
         When a Fund purchases an option on a futures  contract,  its risk
is limited to the amount of the premium,  plus related  transaction costs,
although this entire  amount may be lost. In addition,  in order to profit
from the  purchase  of an option on a  futures  contract,  the Fund may be
required to  exercise  the option and  liquidate  the  underlying  futures
contract,  subject to the availability of a liquid secondary  market.  The
trading  of  options  on  futures  contracts  also  entails  the risk that
changes  in the  value  of the  underlying  futures  contract  will not be
fully  reflected  in the  value  of  the  option,  although  the  risk  of
imperfect  correlation  generally  tends to diminish as the maturity  date
of the futures contract or expiration date of the option approaches.
         "Trading  Limits"  or  "Position  Limits"  may also be imposed on
the  maximum  number of  contracts  which any  person  may hold at a given
time. A contract  market may order the  liquidation of positions  found to
be in  violation  of these  limits and it may impose  other  sanctions  or
restrictions.  The  Investment  Advisor  does  not  believe  that  trading
limits  will have any  adverse  impact on the  strategies  for hedging the
Portfolio's investments.
         Further,  the  trading  of  futures  contracts  is subject to the
risk  of the  insolvency  of a  brokerage  firm or  clearing  corporation,
which  could  make  it  difficult  or  impossible  to  liquidate  existing
positions or to recover excess variation margin payments.
         In addition to the risks of imperfect  correlation  and lack of a
liquid  secondary  market for such  instruments,  transactions  in futures
contracts  involve  risks  related to  leveraging  and the  potential  for
incorrect   forecasts  of  the  direction  and  extent  of  interest  rate
movements within a given time frame.

Noninvestment-Grade Debt Securities
         The  Funds  may   invest  in  lower   quality   debt   securities
(generally  those  rated BB or  lower  by S&P or Ba or lower by  Moody's),
subject to the Funds'  investment  policy which provides that they may not
invest  more than 35% of their  assets in  securities  rated  below BBB by
either  rating  service,  or  in  unrated  securities  determined  by  the
Advisor to be comparable  to  securities  rated below BBB by either rating
service.  These  securities  have moderate to poor protection of principal
and  interest  payments  and  have  speculative   characteristics.   These
securities  involve  greater  risk of  default  or price  declines  due to
changes  in  the  issuer's  creditworthiness  than  investment-grade  debt
securities.  Because the market for lower-rated  securities may be thinner
and less  active  than for  higher-rated  securities,  there may be market
price  volatility  for  these  securities  and  limited  liquidity  in the
resale   market.   Market   prices  for  these   securities   may  decline
significantly  in  periods  of  general  economic   difficulty  or  rising
interest  rates.  Unrated debt  securities may fall into the lower quality
category.  Unrated  securities  usually  are  not  attractive  to as  many
buyers as are rated securities, which may make them less marketable.
         The  quality  limitation  set forth in the  investment  policy is
determined   immediately  after  a  Fund's   acquisition  of  a  security.
Accordingly,  any later  change in  ratings  will not be  considered  when
determining  whether an  investment  complies  with the Fund's  investment
policy.
         When purchasing high-yielding  securities,  rated or unrated, the
Advisors   prepare  their  own  careful  credit  analysis  to  attempt  to
identify  those  issuers  whose  financial  condition  is adequate to meet
future  obligations  or is expected to be adequate in the future.  Through
portfolio  diversification  and credit  analysis,  investment  risk can be
reduced, although there can be no assurance that losses will not occur.

==========================================================================

Fundamental Investment Restrictions
         The following  investment  restrictions and fundamental  policies
may not be changed  without  the consent of the holders of a majority of a
Fund's  outstanding  shares.  Shares  have equal  rights as to  voting.  A
majority  of  the  shares  means  the  lesser  of (i)  67%  of the  shares
represented  at a  meeting  at  which  more  than  50% of the  outstanding
shares are  represented or (ii) more than 50% of the  outstanding  shares.
The Funds may not:
         (1) Purchase common stocks,  preferred stocks, warrants,
         or other equity securities;
         (2) Issue senior  securities,  borrow money,  or pledge,
         mortgage,  or hypothecate  its assets,  except as may be
         necessary to secure  borrowings from banks for temporary
         or emergency  (not  leveraging)  purposes and then in an
         amount not  greater  than 10% of the value of the Fund's
         total  assets at the time of the  borrowing.  Investment
         securities  will not be purchased  while any  borrowings
         are outstanding;
         (3)  Sell  securities  short,   purchase  securities  on
         margin,  or write  put or call  options,  except  to the
         extent   permitted   under   "Transactions   in  Futures
         Contracts"  or elsewhere in the  Prospectus  or SAI. The
         Funds  reserve  the right to  purchase  securities  with
         puts attached. See "Obligations with Puts Attached";
         (4) Underwrite  the securities of other issuers,  except
         to  the   extent   that  the   purchase   of   municipal
         obligations  in  accordance  with the Fund's  investment
         objective  and  policies,   either   directly  from  the
         issuer,  or from an  underwriter  for an issuer,  may be
         deemed an underwriting;
         (5) Make loans to others,  except in accordance with the
         Fund's investment  objective and policies or pursuant to
         contracts  providing  for the  compensation  of  service
         providers by compensating balances;
         (6)   Purchase   or  sell  real   estate,   real  estate
         investment trust securities,  commodities,  or commodity
         contracts, or oil and gas interests,  but this shall not
         prevent a Fund from  investing in municipal  obligations
         secured by real estate or interests therein;
         (7) Invest  25% or more of its assets in the  securities
         of any one  issuer.  Each Funds may invest more than 25%
         of its assets in  obligations  issued or  guaranteed  by
         the U.S.  Government,  its agencies or instrumentalities
         but will  invest  in more  than 20% of such  obligations
         only during abnormal market conditions.  For purposes of
         this  limitation,  the  entity  which  has the  ultimate
         responsibility   for  the  payment  of   principal   and
         interest  on a  particular  security  will be treated as
         its issuer;
         (8) Invest  25% or more of its assets in any  particular
         industry or  industries.  Each Fund may invest more than
         25% of its assets in  obligations  issued or  guaranteed
         by   the    U.S.    Government,    its    agencies    or
         instrumentalities  but will  invest  in more than 20% of
         such    obligations    only   during   abnormal   market
         conditions.  Industrial  development  bonds,  where  the
         payment of principal and interest is the  responsibility
         of  companies  within  the same  industry,  are  grouped
         together as an "industry."

Nonfundamental Investment Restrictions
         Each   Fund  has   adopted   the   following   operating   (i.e.,
nonfundamental)   investment   policies  and  restrictions  which  may  be
changed by the Board of  Directors/Trustees  without shareholder approval.
The Funds may not:
         (1)  Purchase  illiquid  securities  if more than 15% of
         the value of its net assets  would be  invested  in such
         securities;
         (2)  Invest  more  than  5% of the  value  of its  total
         assets in securities  where the payment of principal and
         interest   is  the   responsibility   of  a  company  or
         companies with less than three years' operating history.
         (3) Purchase or retain  securities of an issuer if those
         directors  of the Fund,  each of whom owns more than 1/2
         of 1% of the  outstanding  securities  of  such  issuer,
         together   own   more   than  5%  of  such   outstanding
         securities;
         (4) Invest in  companies  for the purpose of  exercising
         control;  or invest in  securities  of other  investment
         companies,  except as  permitted  under  the  Investment
         Company     Act    or    in     connection     with    a
         director's/trustee's   deferred  compensation  plan,  as
         long as there is no duplication of advisory fees;

                   PURCHASES AND REDEMPTIONS OF SHARES
==========================================================================

         Share  certificates  will be issued at no charge if  requested in
writing by the investor.  No  certificates  will be issued for  fractional
shares.  Purchases  by bank wire  received by 4:00 p.m.,  Eastern time are
immediately  available  federal funds. Your purchases must be made in U.S.
dollars and checks must be drawn on U.S. banks.
         Amounts  redeemed  by  check  redemption  may  be  mailed  to the
investor  without charge.  Amounts of more than $50 and less than $300,000
may be transferred  electronically  at no charge to the investor.  Amounts
of  $1,000  or  more  will be  transmitted  by  wire,  without  charge  by
Calvert,  to the investor's account at a domestic  commercial bank that is
a member of the  Federal  Reserve  System or to a  correspondent  bank.  A
charge of $5 is  imposed on wire  transfers  of less than  $1,000.  If the
investor's  bank  is not a  Federal  Reserve  System  member,  failure  of
immediate  notification  to that  bank  by the  correspondent  bank  could
result in a delay in crediting the funds to the investor's bank account.
         Telephone  redemption  requests that would require the redemption
of shares  purchased  by check or  electronic  funds  transfer  within the
previous  10  business  days may not be  honored.  The Funds  reserve  the
right to modify the telephone redemption privilege.
         To change  redemption  instructions  already given, you must send
a written  notice  addressed to Calvert Group,  c/o NFDS, 6th Floor,  1004
Baltimore,  Kansas City,  MO 64105,  with a voided copy of a check for the
bank  wiring  instructions  to  be  added.  If a  voided  check  does  not
accompany  the request,  then the request must be signature  guaranteed by
a commercial bank,  savings and loan  association,  trust company,  member
firm of any  national  securities  exchange,  or  certain  credit  unions.
Additional  documentation may be required from corporations,  fiduciaries,
and institutional investors.
         The right of  redemption  may be suspended or the date of payment
postponed  for any  period  during  which the New York Stock  Exchange  is
closed (other than customary weekend and holiday  closings),  when trading
on the New York Stock Exchange is restricted,  or an emergency  exists, as
determined  by  the  SEC,  or  if  the   Commission  has  ordered  such  a
suspension for the  protection of  shareholders.  Redemption  proceeds are
normally  mailed or wired the next business day after a proper  redemption
request has been  received,  unless  redemptions  have been  suspended  or
postponed as described above.
         Redemption  proceeds are normally paid in cash.  However,  a Fund
has the right to redeem  shares in assets  other than cash for  redemption
amounts exceeding,  in any 90-day period,  $250,000 or 1% of the net asset
value of the Fund, whichever is less.

Reduced Sales Charges (Class A)
         Each Fund  imposes  reduced  sales  charges for Class A shares in
certain  situations in which the Principal  Underwriter  (which offers the
Fund's  shares  continuously  and  on a  "best  efforts"  basis)  and  the
dealers  selling Fund shares may expect to realize  significant  economies
of  scale  with  respect  to such  sales.  Generally,  sales  costs do not
increase  in  proportion  to the  dollar  amount of the shares  sold;  the
per-dollar  transaction  cost for a sale to an investor  of shares  worth,
for example,  $5,000 is  generally  much higher than the  per-dollar  cost
for a sale of shares worth  $1,000,000.  Thus, the applicable sales charge
declines  as a  percentage  of the  dollar  amount of  shares  sold as the
dollar amount increases.
         When a  shareholder  agrees to make  purchases  of shares  over a
period of time totaling a certain  dollar  amount  pursuant to a Letter of
Intent,  the  Underwriter  and  selling  dealers can expect to realize the
economies of scale  applicable to that stated goal amount.  Thus, the Fund
imposes the sales charge  applicable  to the goal amount.  Similarly,  the
Underwriter   and  selling  dealers  also  experience  cost  savings  when
dealing with existing  shareholders,  enabling the Fund to afford existing
shareholders  the  Right of  Accumulation.  The  Underwriter  and  selling
dealers can also expect to realize  economies  of scale when making  sales
to the  members of certain  qualified  groups  which  agree to  facilitate
distribution  of Fund's shares to their members.  See "Exhibit A - Reduced
Sales Charges" in the Prospectus.

==========================================================================
                       DIVIDENDS AND DISTRIBUTIONS
==========================================================================

         Each Fund  declares and pays monthly  dividends of its net income
to  shareholders  of record as of the close of business on each designated
monthly  record date.  Dividends and  distributions  paid by the Funds may
differ among the classes.  Net investment  income consists of the interest
income  earned on  investments  (adjusted  for  amortization  of  original
issue   discounts  or  premiums  or  market   premiums),   less  estimated
expenses.  Capital  gains,  if any, are normally paid once a year and will
be  automatically  reinvested  at net asset  value in  additional  shares.
Dividends  and  any   distributions   are   automatically   reinvested  in
additional  shares of the Fund,  unless you elect to have the dividends of
$10 or more paid in cash (by check or by Calvert  Money  Controller).  You
may also request to have your  dividends and  distributions  from the Fund
invested  in shares  of any  other  Calvert  Group  Fund at no  additional
charge.  If you  elect  to have  dividends  and/or  distributions  paid in
cash,  and the U.S.  Postal  Service  cannot  deliver the check,  or if it
remains  uncashed  for six  months,  it, as well as future  dividends  and
distributions, will be reinvested in additional shares.

==========================================================================
                               TAX MATTERS
==========================================================================

         Each  Fund  intends  to  qualify  as  a   "regulated   investment
company"  under  Subchapter M of the Internal  Revenue Code (the  "Code").
By so  qualifying,  the Fund will not be subject to  federal  income  tax,
nor to the  federal  excise tax imposed by the Tax Reform Act of 1986 (the
"Act"),  to the extent that it distributes  its net investment  income and
realized capital gains.
         The  Funds'  dividends  of  net  investment   income   constitute
exempt-interest   dividends  on  which   shareholders  are  not  generally
subject  to  federal  income  tax;   however  under  the  Act,   dividends
attributable  to  interest  on  certain  private  activity  bonds  must be
included in federal  alternative  minimum  taxable  income for the purpose
of determining  liability (if any) for individuals  and for  corporations.
Further,  for  corporations,  all  tax-exempt  income  must be taken  into
account in  calculating  "adjusted  current  earnings" for purposes of the
federal  alternative  minimum  tax.  Fund  dividends  derived from taxable
interest  and  distributions  of net  short-term  capital  gains,  whether
taken  in  cash  or  reinvested  in  additional  shares,  are  taxable  to
shareholders  as  ordinary  income and do not  qualify  for the  dividends
received  deduction  for  corporations.  If you held shares for six months
or  less,  losses  must  be  offset  by  the  amount  of   exempt-interest
dividends you received,  and, to the extent of capital gain  distributions
you received,  the loss amount not offset  (disallowed) must be treated as
long-term  capital loss. A  shareholder  may also be subject to some state
and local taxes on dividends and  distributions  from the Funds. The Funds
will notify  shareholders  annually  about the tax status of dividends and
distributions  paid by the Fund and the amount of dividends  withheld,  if
any, during the previous year.
         The Code  provides  that  interest  on  indebtedness  incurred or
continued in order to purchase or carry  shares of a regulated  investment
company which  distributes  exempt-interest  dividends  during the year is
not  deductible.  Entities  or  persons  who are  "substantial  users" (or
persons  related  to  "substantial   users")  of  facilities  financed  by
private   activity  bonds  should   consult  their  tax  advisors   before
purchasing  shares of the Fund.  "Substantial  user" is generally  defined
as  including  a  "non-exempt  person"  who  regularly  uses in  trade  or
business  a part of a  facility  financed  from the  proceeds  of  private
activity bonds.
         Investors  should  note that the  Revenue  Reconciliation  Act of
1989 may require  investors to exclude the initial sales  charge,  if any,
paid on the  purchase of Fund  shares  from the tax basis of those  shares
if the shares are  exchanged  for  shares of  another  Calvert  Group Fund
within 90 days of purchase.  This  requirement  applies only to the extent
that the payment of the  original  sales  charge on the shares of the Fund
causes a reduction  in the sales  charge  otherwise  payable on the shares
of the Calvert  Group Fund  acquired in the  exchange,  and  investors may
treat  sales  charges  excluded  from the basis of the  original  sales as
incurred to acquire the new shares.
         The  Funds  may be  required  to  withhold  31% of any  long-term
capital gain dividends and 31% of each  redemption  transaction  occurring
in a Fund  if:  (a) the  shareholder's  social  security  number  or other
taxpayer  identification  number  ("TIN") is not  provided or an obviously
incorrect  TIN is provided;  (b) the  shareholder  does not certify  under
penalties of perjury that the TIN  provided is the  shareholder's  correct
TIN and that the  shareholder is not subject to backup  withholding  under
section  3406(a)(1)(C)  of the Code  because of  underreporting  (however,
failure  to  provide  certification  as  to  the  application  of  section
3406(a)(1)(C)  will  result  only in backup  withholding  on capital  gain
dividends,  not  on  redemptions);  or  (c) a  Fund  is  notified  by  the
Internal  Revenue  Service  that the TIN  provided by the  shareholder  is
incorrect or that there has been  underreporting  of interest or dividends
by the  shareholder.  Affected  shareholders  will receive  statements  at
least annually specifying the amount withheld.
         In  addition,  each Fund is  required  to report to the  Internal
Revenue  Service the  following  information  with  respect to  redemption
transactions in the Fund: (a) the  shareholder's  name,  address,  account
number and taxpayer  identification  number; (b) the total dollar value of
the redemptions; and (c) the Fund's identifying CUSIP number.
         Certain  shareholders  are,  however,   exempt  from  the  backup
withholding  and  broker  reporting   requirements.   Exempt  shareholders
include: corporations;  financial institutions;  tax-exempt organizations;
individual   retirement   plans;  the  U.S.,  a  State,  the  District  of
Columbia,  a U.S.  possession,  a  foreign  government,  an  international
organization,  or any political  subdivision,  agency, or  instrumentality
of  any  of the  foregoing;  U.S.  registered  commodities  or  securities
dealers;  real estate investment trusts;  registered investment companies;
bank common trust funds;  certain  charitable  trusts; and foreign central
banks of issue.  Non-resident  aliens  also are  generally  not subject to
either  requirement  but,  along with  certain  foreign  partnerships  and
foreign  corporations,   may  instead  be  subject  to  withholding  under
section  1441 of the Code.  Shareholders  claiming  exemption  from backup
withholding  and  broker  reporting  should  call or write  the  Funds for
further information.

==========================================================================
                           VALUATION OF SHARES
==========================================================================

         Fund assets are valued  utilizing  the average bid dealer  market
quotation as furnished by an independent  pricing service.  Securities and
other assets for which market  quotations  are not readily  available  are
valued based on the current  market for similar  securities or assets,  as
determined in good faith by the Fund's  Advisor under the  supervision  of
the Board of Directors/Trustees.
         Each Fund  determines  the net asset  value for each class of its
shares every  business day at the close of the regular  session of the New
York Stock  Exchange  (generally,  4:00 p.m.  Eastern  time),  and at such
other times as may be  necessary  or  appropriate.  They do not  determine
net asset  value on certain  national  holidays  or other day on which the
New York Stock Exchange is closed:  New Year's Day,  Presidents' Day, Good
Friday,  Memorial Day,  Independence Day, Labor Day,  Thanksgiving Day and
Christmas Day.
         Valuations,   market   quotations  and  market   equivalents  are
provided  the Funds by Kenny S&P  Evaluation  Services,  a  subsidiary  of
McGraw-Hill.  The use of Kenny as a pricing  service by the Funds has been
approved  by the  Boards of  Directors/Trustees.  Valuations  provided  by
Kenny are  determined  without  exclusive  reliance  on quoted  prices and
take  into  consideration  appropriate  factors  such as  institution-size
trading in similar  groups of  securities,  yield,  quality,  coupon rate,
maturity, type of issue, trading characteristics, and other market data.

==========================================================================
                  CALCULATION OF YIELD AND TOTAL RETURN
==========================================================================

   
         Each Fund may  advertise  its  "total  return."  Total  return is
calculated  separately  for each  class.  Total  return is  historical  in
nature and is not intended to indicate  future  performance.  Total return
will be quoted for the most  recent  one-year  period,  five-year  period,
and period  from  inception  of the  Fund's  offering  of  shares.  Return
quotations  for  periods  in  excess  of one year  represent  the  average
annual total return for the period  included in the particular  quotation.
Total return is a computation of a Fund's  dividend  yield,  plus or minus
realized or unrealized  capital  appreciation or  depreciation,  less fees
and expenses.  All Class A total return  quotations  reflect the deduction
of the Fund's maximum sales charge  ("return with maximum  load"),  except
quotations  of  "return  without  maximum  load"  which do not  deduct the
sales charge.  Note: "Total Return" as quoted in the Financial  Highlights
section of the Funds'  Annual  Report to  Shareholders,  however,  per SEC
instructions,  does  not  reflect  deduction  of  the  sales  charge,  and
corresponds  to  "return  without  maximum  load" as  referred  to herein.
Return without maximum load should be considered  only by investors,  such
as  participants  in certain  pension plans, to whom the sales charge does
not apply,  or for purposes of  comparison  only with  comparable  figures
which also do not reflect sales charges,  such as Lipper  averages.  Total
return is computed according to the following formula:
    

                             P(1 + T)n = ERV

where P = a hypothetical  initial payment of $1,000;  T = total return;  n
=  number  of  years;  and  ERV  =  the  ending   redeemable  value  of  a
hypothetical  $1,000  payment made at the beginning of the 1, 5 or 10 year
periods at the end of such periods (or portions thereof, if applicable).

         Returns  with  maximum load  (average  annual  total  return) for
Class A shares are as follows:

         A Fund may also  advertise  its "yield" and  "taxable  equivalent
yield." As with total return,  both yield figures are  historical  and are
not intended to indicate future  performance.  "Yield" quotations for each
class of the Fund  refer to the  aggregate  imputed  yield-to-maturity  of
each of the 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  reimbursement),  divided by the average  daily  number of  outstanding
shares for that class  entitled  to receive  dividends  times the  maximum
offering  price on the last day of the  period  (so that the effect of the
sales  charge  is  included  in the  calculation),  compounded  on a "bond
equivalent," or  semi-annual,  basis.  Yield is computed  according to the
following formula:

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

where a = dividends and interest  earned  during the period;  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 maximum  offering  price per share on the
last day of the period.

         The taxable  equivalent  yield is the yield an investor  would be
required to obtain from  taxable  investments  to equal the Fund's  yield,
all or a portion of which may be exempt from  federal  income  taxes.  The
double taxable  equivalent  yield for the combined federal and state level
is  computed  for each  class by taking the  portion  of the yield  exempt
from regular  federal and the specific state income taxes and  multiplying
the  exempt  yield by a factor  based on a stated  income  tax rate,  then
adding the  portion of the yield that is not exempt from  regular  federal
and specific  state income  taxes.  The taxable  equivalent  yield for the
federal  level only is  computed  for each class by taking the  portion of
the yield exempt from  federal  income  taxes and  multiplying  the exempt
yield by a factor  based on a stated  income  tax rate,  then  adding  the
portion of the yield that is not exempt from  federal  income  taxes.  The
factor  which  is  used  to  calculate  the tax  equivalent  yield  is the
reciprocal  of the  difference  between 1 and the  applicable  income  tax
rate, which will be stated in the advertisement.

         The  yield  and  tax  equivalent  yield  for the  Fund's  Class A
shares for the thirty days ending December 31, 1995 is as follows:

             Class A Shares     Tax Equivalent Yield at    Tax Equivalent Yield

_________
<F1>  Officers and trustees deemed to be "interested persons" of the Fund
under the Investment Company Act of 1940, by virtue of their affiliation
with the Fund's Advisor.



         Each  of  the  above   directors/trustees   and   officers  is  a
director/trustee  or officer of each of the  investment  companies  in the
Calvert  Group of Funds with the  exception of Calvert  Social  Investment
Fund,  of which only Messrs.  Baird,  Guffey,  Silby and Sorrell are among
the trustees,  Acacia Capital  Corporation,  of which only Messrs.  Blatz,
Diehl,  Pugh and Sorrell are among the  directors,  Calvert  World  Values
Fund,  Inc.,  of which only  Messrs.  Guffey,  Silby and Sorrell are among
the  directors,  and Calvert New World Fund,  Inc.,  of which only Messrs.
Sorrell  and  Martini are among the  directors.  The address of  directors
and officers,  unless  otherwise noted, is 4550 Montgomery  Avenue,  Suite
1000N, Bethesda, Maryland 20814.
         The  Audit  Committee  of  the  Board  of  Directors/Trustees  is
composed of Messrs.  Baird, Blatz,  Feldman,  Guffey and Pugh. The Board's
Investment Policy Committee is composed of Messrs.  Borts, Diehl,  Gavian,
Rochat, Silby and Sorrell.
         Directors/Trustees  and  officers of the Fund as a group own less
than 1% of each Fund's outstanding shares.
         Directors/Trustees  of the Fund not  affiliated  with the Advisor
currently  receive  an annual fee of  $20,250  for  service as a member of
the Board of  Directors/Trustees  of the Calvert Group of Funds plus a fee
of $750 to $1200  for each  Board and  Committee  meeting  attended;  such
fees are allocated  among the Funds on the basis of their net assets.  For
the 1995  fiscal  period,  the Funds paid  director/trustee  fees of $260,
$357,  $960,  $572,  $439,  $327,  and  $904,  for the  Arizona,  Florida,
Maryland,  Michigan,  New York,  Pennsylvania,  and  Virginia  Portfolios,
respectively.
         Directors/Trustees  of the Fund not  affiliated  with the  Fund's
Advisor may elect to defer  receipt of all or a  percentage  of their fees
and invest  them in any fund in the  Calvert  Family of Funds  through the
Directors/Trustees  Deferred  Compensation  Plan  (shown  as  "Pension  or
Retirement  Benefits Accrued as part of Fund Expenses,"  below).  Deferral
of the fees is designed to  maintain  the parties in the same  position as
if the fees were paid on a current  basis.  Management  believes this will
have a negligible  effect on the Fund's assets,  liabilities,  net assets,
and net income per share,  and will  ensure  that there is no  duplication
of advisory fees.

annually  by the  vote  of a  majority  of the  directors/trustees  of the
Funds who are not parties to the Agreement or  interested  persons of such
parties,  cast in person at a meeting  called for the purpose of voting on
such approval.  The Agreement may be terminated  without penalty by either
party on 60 days' prior written  notice;  it  automatically  terminates in
the event of its assignment.
         Under the  Agreement,  the  Advisor  manages the  investment  and
reinvestment  of the Fund's  assets,  subject to the direction and control
of  the  Funds'  Boards  of  Directors/Trustees.  For  its  services,  the
Advisor  receives an annual fee of 0.60% of the first $500  million of the
Fund's  average  daily net assets,  0.50% of the next $500 million of such
assets, and 0.40% of all assets over $1 billion.
         The advisory  fee is payable  monthly.  The Advisor  reserves the
right  (i) to waive  all or a part of its fee and (ii) to  compensate,  at
its expense,  broker-dealers  in  consideration  of their  promotional and
administrative  services.  The Advisor may  recapture in later  years,  to
the  extent  permitted  by law,  fees it waived  and  expenses  it paid in
prior years.  Specifically,  the Advisor may  recapture any fees waived or
deferred and expenses  reimbursed  for the prior two-year  period,  but in
no event may it  recapture  fees or expenses for any period later than the
two-year period ending  December 31, 1996.  Recapture is permitted only to
the extent it does not result in the Fund's aggregate  expenses  exceeding
an annual  expense  limit of 2.00% of its average  daily net  assets.  The
advisory  fee  incurred  in any given year will be paid in full before any
recapture  fees are paid for a prior year.  Recaptured  fees will apply to
the most recent  suspension/reimbursement  period.  During the 1993 fiscal
period,  the Advisor waived advisory fee of $4,088,  $3,443,  $1,579,  and
$2,144 for the  Maryland,  Michigan,  New York,  and Virginia  portfolios,
respectively,  and reimbursed the portfolios $5,478,  $5,091,  $5,201, and
$5,487 for the  Maryland,  Michigan,  New York,  and Virginia  portfolios,
respectively,  for  other  expenses.  For  the  1994  fiscal  period,  the
Advisor  received  advisory fees of $0, $43, $2,444,  $1,690,  $659, $109,
and  $2,392,  for the  Arizona,  Florida,  Maryland,  Michigan,  New York,
Pennsylvania,  and Virginia  Portfolios,  respectively,  and, for the same
period,  waived  advisory  fees of  $12,272,  $19,011,  $50,168,  $42,150,
$19,257,  $12,665,  and  $41,569,  for  the  Arizona,  Florida,  Maryland,
Michigan, New York, Pennsylvania,  and Virginia Portfolios,  respectively.
For  the  1995  fiscal  period,  the  Advisor  received  advisory  fees of
$17,286,  $25,034,  $270,912,  $37,455, $29,584, $21,720, and $59,769, for
the Arizona,  Florida,  Maryland,  Michigan, New York,  Pennsylvania,  and
Virginia  Portfolios,  respectively,  and,  for the  same  period,  waived
advisory fees of $14,027,  $15,204,  $38,349,  $19,899,  $21,022, $16,922,
and  $29,520,  for the Arizona,  Florida,  Maryland,  Michigan,  New York,
Pennsylvania, and Virginia Portfolios, respectively.
         The  Advisor  provides  each  Fund  with  investment  advice  and
research,  pays  the  salaries  and  fees  of all  directors/trustees  and
executive  officers of the Fund who are  principals  of the  Advisor,  and
pays certain Fund  advertising  and  promotional  expenses.  The Funds pay
all other  administrative  and operating  expenses,  including:  custodial
fees;  shareholder  servicing,  dividend  disbursing  and transfer  agency
fees;   administrative   service  fees;   federal  and  state   securities
registration fees;  insurance premiums;  trade association dues; interest,
taxes and  other  business  fees;  legal and  audit  fees;  and  brokerage
commissions  and other  costs  associated  with the  purchase  and sale of
portfolio securities.
         The Advisor has agreed to reimburse the Funds for all expenses,
excluding brokerage, taxes, interest, and extraordinary items exceeding,
on a pro rata basis, the most restrictive expense limitation in those
states which the Fund's shares are qualified for sale.

                         ADMINISTRATIVE SERVICES
==========================================================================

         Calvert   Administrative   Services   Company,   a   wholly-owned
subsidiary  of  Calvert  Group,  Ltd.,  has been  retained  by the Fund to
provide certain  administrative  services  necessary to the conduct of the
Fund's  affairs.  Such services  include the  preparation of corporate and
regulatory  reports  and  filings,  portfolio  accounting,  and the  daily
determination  of net  investment  income  and net asset  value per share.
Calvert  Administrative  Services  Company receives an annual fee of 0.10%
of each Fund's average net assets for providing  such services.  The Funds
waived the fee for the 1993, 1994, and 1995 fiscal periods.

==========================================================================
                          METHOD OF DISTRIBUTION
==========================================================================

   
         The  Funds  have   entered   into  an   agreement   with  Calvert
Distributors,  Inc. ("CDI"),  whereby CDI, acting as principal underwriter
for the Series,  makes a continuous  offering of the Series' securities on
a  "best   efforts"   basis.   Prior  to  April  1,  1995,  the  principal
underwriter was Calvert Securities  Corporation  ("CSC").  Under the terms
of the  agreement,  CDI  bears  all its  expenses  of  providing  services
pursuant  to the  agreement,  including  payment  of any  commissions  and
service  fees.  CDI  receives  all sales  charges  imposed  on the  Funds'
shares and compensates  broker-dealer  firms for sales of such shares (see
"Alternative  Sales  Options"  in  the  Prospectus).  CDI is  entitled  to
receive   reimbursement   of   distribution   expenses   pursuant  to  the
Distribution  Plans  (see  below).  For the 1993,  1994,  and 1995  fiscal
periods,  the Funds' Class A shares paid no  Distribution  Plan  expenses.
In fiscal  1993,  CSC  received  sales  charges  in  excess of the  dealer
reallowance  of $22,295,  $4,909,  $11,439,  and $27,524 for the Maryland,
Michigan,  New York,  and Virginia  portfolios,  respectively.  For fiscal
1994,  CSC received  sales charges in excess of the dealer  reallowance of
$7,757,  $20,467,   $29,470,  $0,  $7,872,  $718,  and  $43,471,  for  the
Arizona,  Florida,  Maryland,   Michigan,  New  York,  Pennsylvania,   and
Virginia  Portfolios,  respectively.  For fiscal 1995,  CDI received sales
charges  in excess of the dealer  reallowance  of  $3,016,  $287,  $6,482,
$1,441,  $3,925, $2,788, and $6,479, for the Arizona,  Florida,  Maryland,
Michigan, New York, Pennsylvania, and Virginia Portfolios, respectively.
         Pursuant to Rule 12b-1 under the  Investment  Company Act of 1940
("1940  Act"),  the Funds have adopted  Distribution  Plans (the  "Plans")
which   permit  them  to  pay  certain   expenses   associated   with  the
distribution  of its shares.  Such  expenses may not exceed,  on an annual
basis,  0.25% of the Funds'  Class A average  daily net  assets.  Expenses
under the Class C Plan may not exceed,  on an annual  basis,  0.80% of the
Class C average  daily net  assets.  For the 1994 fiscal  period,  Class C
Distribution Plan expenses were $2,252,  $1,812,  $5,973,  $5,342, $3,937,
$4,046, and $10,851, for the Arizona,  Florida,  Maryland,  Michigan,  New
York, Pennsylvania,  and Virginia Portfolios,  respectively.  For the 1995
fiscal  period,  Class C Distribution  Plan expenses were $5,806,  $4,952,
$18,167,   $11,234,  $14,199,  $11,131,  and  $23,210,  for  the  Arizona,
Florida,  Maryland,   Michigan,  New  York,  Pennsylvania,   and  Virginia
Portfolios, respectively.
         The  Plans  were  approved  by the  Board of  Directors/Trustees,
including the  Directors/Trustees  who are not "interested persons" of the
Funds  (as that  term is  defined  in the 1940 Act) and who have no direct
or indirect  financial  interest in the  operation  of the Plans or in any
agreements  related to the Plans.  The  selection  and  nomination  of the
Directors/Trustees   who  are  not  interested  persons  of  the  Fund  is
committed to the discretion of such disinterested  Directors/Trustees.  In
establishing  the  Plans,  the   Directors/Trustees   considered   various
factors    including   the   amount   of   the   distribution   fee.   The
Directors/Trustees  determined that there is a reasonable  likelihood that
the Plans will benefit the Funds and their shareholders.
         The  Plans  may  be  terminated  by  vote  of a  majority  of the
non-interested   Directors/Trustees   who  have  no  direct  or   indirect
financial  interest  in  the  Plans,  or by  vote  of a  majority  of  the
outstanding  shares of the  respective  Fund and class.  Any change in the
Plans that would materially  increase the  distribution  cost to the Funds
requires  approval of the  shareholders of the affected class;  otherwise,
the Plans may be amended by the  Directors/Trustees,  including a majority
of the non-interested Directors/Trustees as described above.
         The Plans will  continue  in effect  successive  one-year  terms,
provided that such  continuance is  specifically  approved by (i) the vote
of a majority of the  Directors/Trustees  who are not parties to the Plans
or  interested  persons  of any  such  party  and who  have no  direct  or
indirect  financial  interest  in  the  Plans,  and  (ii)  the  vote  of a
majority of the entire Board of Directors/Trustees.
         Apart from the Plans,  the  Advisor,  at its  expense,  may incur
costs and pay expenses  associated with the  distribution of shares of the
Funds.

==========================================================================

   
         Calvert  Shareholder  Services,  Inc.  ("CSSI"),  a subsidiary of
Calvert Group,  Ltd.,  and Acacia  Mutual,  has been retained by the Funds
to act as  transfer  agent,  dividend  disbursing  agent  and  shareholder

shareholder   inquiries  and   instructions   concerning  their  accounts;
crediting   and   debiting   shareholder   accounts  for   purchases   and
redemptions  of  Fund  shares  and  confirming  such  transactions;  daily
updating of  shareholder  accounts to reflect  declaration  and payment of
dividends;  and  preparing  and  distributing  semi-annual  statements  to
shareholders  regarding  their  accounts.   For  such  services,   Calvert
Shareholder  Services,  Inc., receives compensation based on the number of
shareholder  accounts  and the  number of  transactions.  The fees paid by
the Series to Calvert  Shareholder  Services,  Inc. for fiscal period 1993
were $665,  $324,  $451,  and $707 for the Maryland,  Michigan,  New York,
and Virginia  portfolios,  respectively.  For the 1994 fiscal period, CSSI
received $1,495,  $1,143,  $6,690, $2,771, $3,207, $2,022, and $5,258, for
the Arizona,  Florida,  Maryland,  Michigan, New York,  Pennsylvania,  and

received $4,131,  $3,389,  $9,630, $5,414, $6,915, $4,711, and $8,735, for
the Arizona,  Florida,  Maryland,  Michigan, New York,  Pennsylvania,  and
Virginia Portfolios, respectively.

                  INDEPENDENT ACCOUNTANTS AND CUSTODIANS
==========================================================================

   
         Coopers  and  Lybrand  L.L.P.  has been  selected by the Board of
Directors to serve as  independent  accountants  for all portfolios of the
Fund for fiscal year 1996.  State Street Bank & Trust  Company,  N.A., 225
Franklin  Street,  Boston,  MA 02110,  serves as custodian of the Series's
investments.  First  National Bank of Maryland,  25 South Charles  Street,
Baltimore,  Maryland  21203 acts as  custodian  of certain of the Series's
cash  assets.  Neither  custodian  has any  part in  deciding  the  Fund's
investment  policies or the choice of securities  that are to be purchased
or sold by the Series.
    

==========================================================================
                          PORTFOLIO TRANSACTIONS
==========================================================================

   
         Portfolio  transactions  are  undertaken  on the  basis  of their
desirability from an investment  standpoint.  Investment decisions and the
choice of brokers  and dealers  are made by the Fund's  Advisor  under the
direction and supervision of the Fund's Board of Directors/Trustees.
         Broker-dealers  who execute  portfolio  transactions on behalf of
the Funds are selected on the basis of their  professional  capability and
the  value  and  quality  of  their  services.  The  Advisor  may  execute
portfolio  transactions  with or  through  broker-dealers  who  have  sold
shares  of the Fund.  However,  such  sales  will not be a  qualifying  or
disqualifying   factor  in  a  broker-dealer's   selection  nor  will  the
selection  of any  broker-dealer  be based on the  volume  of Fund  shares
sold.  The Advisor or its  affiliate  may  compensate,  at their  expense,
such   broker-dealers   in   consideration   of  their   promotional   and
administrative services.
         The  Advisor  anticipates  the  portfolio  turnover  of the Funds
during  the first  full  fiscal  year to be less than 25%.  The  portfolio
turnover  for the 1993  fiscal  period was 14% and 28%,  for the  Maryland
and Virginia  portfolios,  respectively,  and 0% each for the Michigan and
New York portfolios.  For the 1994 fiscal period,  the portfolio  turnover
was 22%,  93%,  77%,  65%,  56%,  96%, and 65%, for the Arizona,  Florida,
Maryland,  Michigan,  New York,  Pennsylvania,  and  Virginia  Portfolios,
respectively.  For the 1995 fiscal  period,  the  portfolio  turnover  was
10%,  44%,  11%,  22%,  13%,  17%,  and  11%,  for the  Arizona,  Florida,
Maryland,  Michigan,  New York,  Pennsylvania,  and  Virginia  Portfolios,
respectively.

                           GENERAL INFORMATION
==========================================================================

   
         Calvert  Municipal  Fund,  Inc.,  was  organized as a corporation
under the  General  Corporation  Law of the State of  Maryland on February
4,  1992.  The Fund  includes  the  following  series:  (list  all  except
Florida)  Calvert  National   Municipal   Intermediate  Fund  and  Calvert
California   Municipal   Intermediate  Fund,  Calvert  Maryland  Municipal
Intermediate  Fund.  Prior to March 1, 1994,  Calvert  National  Municipal
Intermediate Fund was known as Calvert Intermediate Municipal Fund.
         First  Variable Rate Fund for  Government  Income was  originally
organized as a Maryland corporation,  and became a Massachusetts  business
trust  on April  30,  1984.  It has two  series,  one  doing  business  as
Calvert  First  Government  Money  Market  Fund,  and the  other,  Calvert
Florida Municipal Intermediate Fund.
         Each  share  of  each  Fund  represents  an  equal  proportionate
interest  in that Fund  with each  other  share  and is  entitled  to such
dividends  and  distributions  out of the income  belonging to such series
as  declared  by the  Board.  The Funds  offer  two  separate  classes  of
shares:  Class A and Class C. Each class represents  interests in the same
portfolio of  investments,  but, as further  described in the  prospectus,
each class is subject to  differing  sales  charges  and  expenses,  which
will result in  differing  net asset  values and  distributions.  Upon any
liquidation  of the  Funds,  shareholders  of each class are  entitled  to
share pro rata in the net  assets  belonging  to that Fund  available  for
distribution.
         The  Funds  will  send  shareholders  unaudited  semi-annual  and
audited  annual  reports  that will include the Funds' net asset value per
share,  portfolio  securities,  income and expenses,  and other  financial
information.
         The  Funds'  registration   statements,   containing   additional
information,  are on file with the Securities and Exchange  Commission and
are available to the public.

                                 APPENDIX
==========================================================================

Municipal Obligations
         Municipal  obligations  are debt  obligations  issued by  states,
cities,  municipalities,  and their  agencies to obtain  funds for various
public  purposes.  Such purposes  include the construction of a wide range
of public  facilities,  the  refunding  of  outstanding  obligations,  the
obtaining  of funds for  general  operating  expenses,  and the lending of
funds to other public  institutions and facilities.  In addition,  certain
types of  industrial  development  bonds  are  issued  by or on  behalf of
public  authorities  to obtain  funds for many  types of local,  privately
operated  facilities.  Such  debt  instruments  are  considered  municipal
obligations  if the interest  paid on them is exempt from  federal  income
tax in the opinion of bond  counsel to the issuer.  Although  the interest
paid  on  the  proceeds   from  private   activity   bonds  used  for  the
construction,  equipment,  repair or  improvement  of  privately  operated
industrial  or  commercial  facilities  may be exempt from federal  income
tax,  current federal tax law places  substantial  limitations on the size
of such issues.
         Municipal   obligations   are  generally   classified  as  either
"general  obligation" or "revenue"  bonds.  General  obligation bonds are
secured by the issuer's  pledge of its faith,  credit and taxing power for
the payment of  principal  and  interest.  Revenue  bonds are payable from
the revenues  derived from a  particular  facility or class of  facilities
or, in some  cases,  from the  proceeds  of a special  excise tax or other
specific   revenue  source,   but  not  from  the  general  taxing  power.
Tax-exempt  industrial  development  bonds are in most cases revenue bonds
and do not  generally  carry  the  pledge  of the  credit  of the  issuing
municipality.  There  are,  of  course,  variations  in  the  security  of
municipal obligations,  both within a particular  classification and among
classifications.
         Municipal  obligations  are  generally  traded  on the basis of a
quoted  yield to  maturity,  and the price of the  security is adjusted so
that  relative  to the stated  rate of  interest it will return the quoted
rate to the purchaser.
         Short-term and  limited-term  municipal  obligations  include Tax
Anticipation Notes,  Revenue  Anticipation Notes, Bond Anticipation Notes,
Construction  Loan Notes,  and Discount  Notes.  The  maturities  of these
instruments  at the time of  issue  generally  will  range  between  three
months and one year.  Pre-Refunded  Bonds with longer  nominal  maturities
that are due to be retired  with the  proceeds of an  escrowed  subsequent
issue  at a  date  within  one  year  and  three  years  of  the  time  of
acquisition  are also  considered  short-term and  limited-term  municipal
obligations.

Municipal Note and Bond Ratings
Description  of Moody's  Investors  Service,  Inc.'s  ratings of state and
municipal notes:
         Moody's   ratings  for  state  and  municipal   notes  and  other
short-term  obligations are designated  Moody's  Investment Grade ("MIG").
This distinction is in recognition of the differences  between  short-term
credit risk and long-term risk.
         MIG 1: Notes  bearing this  designation  are of the best quality,
enjoying  strong  protection  from  established  cash  flows of funds  for
their servicing or from  established and broad-based  access to the market
for refinancing, or both.
         MIG2:  Notes bearing this  designation are of high quality,  with
margins of  protection  ample  although  not so large as in the  preceding
group.
         MIG3:  Notes bearing this  designation are of favorable  quality,
with all  security  elements  accounted  for but  lacking  the  undeniable
strength  of the  preceding  grades.  Market  access for  refinancing,  in
particular, is likely to be less well established.
         MIG4:  Notes bearing this  designation  are of adequate  quality,
carrying  specific  risk  but  having  protection   commonly  regarded  as
required of an investment  security and not  distinctly  or  predominantly
speculative.

Description  of  Moody's  Investors   Service   Inc.'s/Standard  &  Poor's
municipal bond ratings:
         Aaa/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.  This  rating  indicates  an  extremely  strong
capacity to pay principal and interest.
         Aa/AA:   Bonds  rated  AA  also  qualify  as  high-quality   debt
obligations.  Capacity to pay principal  and interest is very strong,  and
in the  majority  of  instances  they differ from AAA issues only in small
degree.  They are rated  lower  than the best  bonds  because  margins  of
protection  may  not be as  large  as in Aaa  securities,  fluctuation  of
protective  elements  may be of greater  amplitude,  or there may be other
elements  present which make long-term  risks appear  somewhat larger than
in Aaa securities.
         A/A:  Upper-medium grade obligations.  Factors giving security to
principal  and  interest  are  considered  adequate,  but  elements may be
present  which make the bond  somewhat  more  susceptible  to the  adverse
effects of circumstances and economic conditions.
         Baa/BBB:  Medium  grade  obligations;  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.
         Ba/BB,  B/B,  Caa/CCC,  Ca/CC:  Debt rated in these categories is
regarded  as  predominantly  speculative  with  respect to capacity to pay
interest and repay principal.  There may be some large  uncertainties  and
major  risk  exposure  to  adverse  conditions.  The  higher the degree of
speculation, the lower the rating.
         C/C: This rating is only for no-interest income bonds.
         D: Debt in default;  payment of interest  and/or  principal is in
arrears.

         I am making no commitment to purchase shares, but if my
purchases within thirteen months from the date of my first purchase do
not aggregate the minimum amount specified above, I will pay the
increased amount of sales charges prescribed in the terms of escrow
described below. I understand that 4.75% of the minimum dollar amount
specified above will be held in escrow in the form of shares (computed
to the nearest full share). These shares will be held subject to the
terms of escrow described below.

         From the initial purchase (or subsequent purchases if
necessary), 4.75% of the dollar amount specified in this Letter shall be
held in escrow in shares of the Fund by the Fund's transfer agent. For
example, if the minimum amount specified under the Letter is $50,000,
the escrow shall be shares valued in the amount of $2,375 (computed at
the public offering price adjusted for a $50,000 purchase). All
dividends and any capital gains distribution on the escrowed shares will
be credited to my account.

         If the total minimum investment specified under the Letter is
completed within a thirteen month period, escrowed shares will be
promptly released to me. However, shares disposed of prior to completion
of the purchase requirement under the Letter will be deducted from the
amount required to complete the investment commitment.

         Upon expiration of this Letter, the total purchases pursuant to
the Letter are less than the amount specified in the Letter as the
intended aggregate purchases, Calvert Distributors, Inc. ("CDI") will
bill me for an amount equal to the difference between the lower load I
paid and the dollar amount of sales charges which I would have paid if
the total amount purchased had been made at a single time. If not paid
by the investor within 20 days, CDI will debit the difference from my
account. Full shares, if any, remaining in escrow after the
aforementioned adjustment will be released and, upon request, remitted
to me.

         I irrevocably constitute and appoint CDI as my
attorney-in-fact, with full power of substitution, to surrender for
redemption any or all escrowed shares on the books of the Fund. This
power of attorney is coupled with an interest.

         The commission allowed by Calvert Distributors, Inc. to the
broker-dealer named herein shall be at the rate applicable to the
minimum amount of my specified intended purchases.

         The Letter may be revised upward by me at any time during the
thirteen-month period, and such a revision will be treated as a new
Letter, except that the thirteen-month period during which the purchase
must be made will remain unchanged and there will be no retroactive
reduction of the sales charges paid on prior purchases.

         In determining the total amount of purchases made hereunder,
shares disposed of prior to termination of this Letter will be deducted.
My broker-dealer shall refer to this Letter of Intent in placing any
future purchase orders for me while this Letter is in effect.

Ladies and Gentlemen:


         As counsel to Calvert Group, Ltd., it is my opinion that the
securities being registered by this Post-Effective Amendment No. 13 will
be legally issued, fully paid and non-assessable when sold.  My opinion
is based on an examination of documents related to Calvert Municipal
Fund, Inc. (the "Fund"), including its Articles of Incorporation, other
original or photostatic copies of Fund records, certificates of public
officials, documents, papers, statutes, or authorities as I deemed
necessary to form the basis of this opinion.

         I therefore consent to filing this opinion of counsel with the
Securities and Exchange Commission as an Exhibit to the Fund's
Post-Effective Amendment No. 13 to its Registration Statement.


                                               Sincerely,

                      Rule 18f-3 Multiple Class Plan


                          Calvert Municipal Fund


         Rule 18f-3 under the Investment Company Act of 1940, as amended
(the "1940 Act"), requires that an investment company desiring to offer
multiple classes of shares pursuant to the Rule adopt a plan setting
forth the differences among the classes with respect to shareholder
services, distribution arrangements, expense allocations and any related
conversion features or exchange privileges.  Any material amendment to
the plan must be approved by the investment company's Board of
Trustees/Directors, including a majority of the disinterested Board
members, who must find that the plan is in the best interests of each
class individually and the investment company as a whole.

         1.       Class Designation.  Fund shares shall be designated
either Class A or Class C.

         2.       Differences in Availability.  Class A shares and Class
C shares shall both be available through the same distribution channels,
except that Class C shares; (1) may not be available through some
dealers, and, (2) are not available for purchases of $1 million or more.

         3.       Differences in Services.  The services offered to
shareholders of each Class shall be substantially the same, except that
Rights of Accumulation, Letters of Intent and Reinvestment Privileges
shall be available only to holders of Class A shares.

         4.       Differences in Distribution Arrangements.  Class A
shares shall be offered with a front-end sales charge, as such term is
defined in Article III, Section 26(b), of the Rules of Fair Practice of
the National Association of Securities Dealers, Inc.  The amount of the
front-end sales charge on Class A shares is set forth at Exhibit I.
Class A shares shall be subject to a Distribution Plan adopted pursuant
to Rule 12b-1 under the 1940 Act.  The amount of the Distribution Plan
expenses for Class A shares, as set forth at Exhibit I, are used to pay
the Fund's Distributor for distributing the Fund's Class A shares.  This
