sell  shares of the Fund.  If you request a wire  redemption  of less than
$1,000, you will be charged a $5 wire fee.

B.  Annual  Fund  Operating  Expenses  are based on the Fund's  historical
expenses.   Management  Fees  are  paid  by  the  Fund  to  Calvert  Asset
Management Company,  Inc.  ("Investment  Advisor") for managing the Fund's
investments  and  business  affairs.  The Fund incurs  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 Fund's  yield or share  price and are not
charged  directly to  individual  shareholder  accounts.  Please  refer to
"Management of the Fund" for further information.

INVESTMENT OBJECTIVE AND POLICIES

The Fund seeks to earn the  highest  possible  yield  consistent
with  safety,   liquidity,   and  preservation  of  capital.  In
pursuing  its  objective,   the  Fund  invests  solely  in  debt
obligations  issued or  guaranteed  by the  United  States,  its
agencies or  instrumentalities,  assignments of interest in such
obligations,   and  commitments  to  purchase  such  obligations
("U.S. Government-backed  obligations").  The Fund may invest in
U.S.   Government-backed   obligations   subject  to  repurchase
agreements with the recognized securities dealers and banks.

U.S. Government Obligations

Obligations issued by the U.S.  Treasury,  such as U.S. Treasury
bills,  notes and  bonds,  are  supported  by the full faith and
credit of the U.S. Government.

Securities  issued by the U.S.  Government  include a variety of
Treasury  securities  which differ only in their interest rates,
maturities,   and  time  of  issuance.  In  addition,   numerous
agencies  (such as  Government  National  Mortgage  Association,
Farmers Home  Administration,  Federal  Housing  Administration,
and Small Business  Administration) and instrumentalities  (such
as Federal  Home Loan  Mortgage  Corporation,  Federal  National
Mortgage  Association,  Student Loan Marketing  Association  and
Federal  Home Loan Bank) issue or  guarantee  obligations.  Some
of these  securities  are supported by the full faith and credit
of the U.S.  Treasury;  others are supported by the right of the
issuer to borrow from the  Treasury;  still others are supported
only by the credit of the instrumentality.

Repurchase Agreements

The Fund may enter into repurchase  agreements.  In a repurchase
agreement,  the Fund buys a  security  subject  to the right and
obligation   to  sell  it  back  at  a   higher   price.   These
transactions  must be  fully  secured  at all  times,  but  they
involve  some  credit  risk  to  the  Fund  if the  other  party
defaults  on  its   obligation   and  the  Fund  is  delayed  or
prevented from liquidating the collateral.

Bank CDs

The Fund may also  invest in  certificates  of deposit and other
debt  obligations  of  commercial  banks,   savings  banks,  and
savings  and loan  associations  having  assets  of less than $1
billion,   provided   that   the   principal   amount   of  such
certificate   is  insured  in  full  by  the   Federal   Deposit
Insurance  Corporation  ("FDIC").  The  FDIC  presently  insures
accounts up to $100,000;  interest  earned above $100,000 is not
insured by the FDIC.

Variable Rate Obligations

The Fund may invest in variable and floating  rate  obligations.
Variable  rate  obligations  have  a  yield  which  is  adjusted
periodically  based  upon  changes  in the  level of  prevailing
interest  rates.  Floating  rate  obligations  have an  interest
rate  fixed to a known  lending  rate,  such as the prime  rate,
and  are   automatically   adjusted   when  that  rate  changes.
Variable  and  floating  rate  obligations  lessen  the  capital
fluctuations  usually inherent in fixed income  investments,  to
diminish the risk of capital  depreciation  of  investments  and
shares;   but  this  also  means  that  should   interest  rates
decline,  the yield of each class of the Fund will  decline  and
the  Fund  would  not  have as many  opportunities  for  capital
appreciation of Fund investments.

Other Policies

Investments  in  Government-backed  securities  are  subject  to
certain  market  risks,  and there is, of course,  no  assurance
that the Fund  will be  successful  in  meeting  its  investment
objective.

The Fund may  temporarily  borrow  money from banks (and  pledge
its  assets  to  secure  such   borrowing)  to  meet  redemption
requests.  Such  borrowing  may not  exceed  25% of the value of
the  Fund's  total   assets.   The  Fund  has  adopted   certain
fundamental  investment  restrictions  which  are  discussed  in
detail  in  the  Statement  of  Additional  Information.  Unless
specifically   noted   otherwise,   the  investment   objective,
policies and  restrictions  of the Fund are  fundamental and may
not be changed without shareholder approval.

YIELD

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

   
The Fund may  advertise  "yield" and  "effective  yield."  Yield
figures are based on  historical  earnings  and are not intended
to indicate future  performance.  The "yield" of the Fund refers
to the actual  income  generated  by an  investment  in the Fund
over a particular base period,  stated in the advertisement.  If
the  base  period  is less  than one  year,  the  yield  will be
"annualized."  That is,  the amount of income  generated  by the
investment  during the base  period is  assumed to be  generated
over a  one-year  period  and is  shown as a  percentage  of the
investment.  The  "effective  yield" is  calculated  like yield,
but  assumes  reinvestment  of  earned  income  and  accordingly
produces a higher figure.  The effective  yield will be slightly
higher  than the  yield  because  of the  compounding  effect of
this assumed reinvestment.
    

MANAGEMENT OF THE FUND

The Board of Trustees supervises the activities and reviews
its contracts with companies that provide the Fund with
services.

but special  meetings  may be called for certain  purposes  such
as  electing  Trustees,   changing  fundamental   policies,   or
approving a management contract.  As a shareholder,  you receive
one vote for each share you own.

SHAREHOLDER GUIDE

Opening An Account

   
You can buy shares of the Fund in several ways which are
described here.
    

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

To invest in any of  Calvert's  tax-deferred  retirement  plans,
please   call   Calvert   Group  at   800-368-2748   to  receive

NET ASSET VALUE

The Fund's shares are sold without a sales charge.

   
Net asset  value,  or "NAV",  refers to the worth of one  share.
NAV is  computed  by adding  the  value of a Fund's  investments
plus  cash and  other  assets,  deducting  liabilities  and then
dividing  the  result by the number of shares  outstanding.  The
NAV is  calculated  at the  close of the  Fund's  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
Fund is open for business  each day the New York Stock  Exchange
is  open.  The  Fund  securities  are  valued  according  to the
"amortized  cost"  method,  which is intended to  stabilize  the
NAV at $1.00 per share.
    

All  purchases  of Fund shares will be  confirmed  and credited
to your account in full and fractional  shares  (rounded to the
nearest   1/100  of  a  share).   The  Fund  may  send  monthly
statements  in lieu of  immediate  confirmations  of  purchases
and redemptions.

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.

   
All of your  purchases  must be made in U.S.  dollars and checks
must be drawn  on U.S.  banks.  No cash  will be  accepted.  The
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 is not paid,  your  purchase will be canceled and you
will be  charged  a $10 fee plus  costs  incurred  by the  Fund.
When you  purchase by check or with  Calvert  Money  Controller,
those  funds  will be on hold for up to 10  business  days  from
the date of receipt.  During that  period,  redemptions  against
those funds  (including  drafts)  will not be honored.  To avoid
this  collection  period,  you can wire federal  funds from your
bank, which may charge you a fee.
    

   
Your purchase will be processed at the net asset value
calculated after your order is received and accepted. The
Portfolio attempts to maintain a constant net asset value of
$1.00 per share. Except in the case of telephone orders,
investors whose payments are received in or converted into
federal funds by 12:30 p.m. Eastern time by the custodian will
receive the dividend declared that day. If your wire purchase
is received after 12:30 p.m. Eastern time, your account will
begin earning dividends on the next business day. A telephone
order placed to Calvert Institutional Marketing Services by
12:30 p.m. Eastern time will become effective at the price
determined at 5 p.m. Eastern time and the shares purchased
will receive the dividend declared on Fund shares that day if
federal funds are received by the custodian by 5 p.m. Eastern
time. Exchanges begin earning dividends the next business day
after the exchange request is received by mail or by
telephone. Purchases received by check will begin earning
dividends the next business day. As a convenience, check
purchases can be received at Calvert's offices for overnight
mail delivery to the transfer agent and will be credited the
next business day. Any check purchase received without an
investment slip may cause delayed crediting.
    

EXCHANGES

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

If your investment  goals change,  the Calvert Group 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.  Before you make
an  exchange  from  a  Fund  or   Portfolio,   please  note  the
following:
    

      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.

      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.

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

   
For  purposes  of  the  exchange  privilege,  the  Portfolio  is
related  to  Summit  Cash  Reserves   Fund  by  investment   and
investor  services.  The Fund reserves the right to terminate or
modify the exchange privilege with 60 days written notice.

free service on your application.

   
This service  allows you to authorize  electronic  transfers of

investments  (minimum  $50) into your  Calvert  Group  account.
After  you give us  proper  authorization,  your  bank  account

arrangements  for systematic  monthly or quarterly  redemptions

telephone  privileges unless you elect otherwise.  The Fund, the
transfer  agent and their  affiliates  are not liable for acting
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.

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
the 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  the  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.
    

If you sell shares by  telephone  or written  request,  you will
receive  dividends  through the date the request is received and
processed.  If you  write a draft  to sell  shares,  the  shares
will earn  dividends  until the draft is  presented  to the Fund
to be paid.

Minimum account balance is $1,000.

   
Please  maintain a balance in each of your  accounts of at least
$1,000.  If the  balance  in your  money  market  account  falls
below  the  $1,000  minimum  during  a  month,  a $3 fee will be
charged to your  account.  This fee is paid to the  portfolio to
offset the generally higher costs of small dollar accounts.
    

HOW TO SELL YOUR SHARES

Draftwriting

   
You may redeem shares in your account by writing a draft for
at least $250. If you complete and return a signature card for
Draftwriting, the Fund will mail bank drafts to you, printed
with your name and address. Generally, there is no charge to
you for the maintenance of this service or the clearance of
drafts, but the Fund will charge a service fee for drafts
returned for insufficient funds. The Fund will charge $25 for
any stop payments on drafts. As a service to shareholders,
shares may be automatically transferred between your Calvert
accounts to cover drafts you have written.  The signature of
only one authorized signer is required to honor a draft.

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

Each year, the Fund distributes substantially all of its net
investment income to shareholders.

Dividends  from the Fund's net  investment  income are  declared
daily  and 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.
Dividend and  distribution  payments will vary between  classes;
dividend payments will generally be higher for Class A shares.

Dividend payment options

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).  Dividends and  distributions  from the Fund
may also be invested in shares of any other  Calvert  Group Fund
or  Portfolio,  at no  additional  charge.  You must  notify the
Fund in writing 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.

Federal Taxes

In  January,  the Fund  will mail you Form  1099-DIV  indicating
the  federal  tax  status  of  dividends  and any  capital  gain
distributions  paid to you by the Fund  during  the  past  year.
Dividends  and  distributions  are taxable to you  regardless of
whether  they  are  taken  in  cash  or  reinvested.  Dividends,
including  short-term  capital  gains,  are  taxable as ordinary
income.  Distributions  from long-term capital gains are taxable
as  long-term  capital  gains,  regardless  of how long you have
owned Fund shares.

Other Tax Information

In  addition  to federal  taxes,  you may be subject to state or
local taxes on your  investment,  depending  on the laws in your
area.  You  will  be  notified  to  the  extent,  if  any,  that
dividends  reflect  interest   received  from  U.S.   government
securities.  Such  dividends  may be exempt from  certain  state
income taxes.

Taxpayer Identification Number

If we do not have  your  correct  Social  Security  or  Taxpayer
Identification   Number   ("TIN")   and   a   signed   certified
application  or Form  W-9,  Federal  law  requires  the  Fund to
withhold  31%  of  your  dividends.  In  addition,  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  Fund  reserves  the  right to  reject  any new
account  or  any   purchase   order  for  failure  to  supply  a
certified TIN.

     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.

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.

     The  example,   which  is   hypothetical,   should  not  be   considered  a
representation  of past or future  expenses.  Actual  expenses  may be higher or
lower than those shown.

     Explanation  of  Table:  The  purpose  of the  table  is to  assist  you in
understanding  the various costs and expenses that an investor may bear directly
(shareholder transaction costs) or indirectly (annual fund operating expenses).

     A. Shareholder  Transaction  Costs are charges you pay when you buy or sell
shares of your Fund.  See  "Reduced  Sales  Charges"  at Exhibit A to see if you
qualify  for  possible  reductions  in the sales  charge.  If you request a wire
redemption of less than $1,000, you will be charged a $5 wire fee.

   
     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. 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,
Rule 12b-1 will be limited to 0.15% and may thereafter be 0.25%. The Advisor may
voluntarily  defer fees or assume  expenses of the Funds.  The  following  table
shows what Total Fund Operating  Expenses would have been, without the voluntary
reimbursement of expenses:
Fund Name                      Total Expenses
Arizona                             1.37%
Florida                             .95%
Maryland                            1.04%
Michigan                            1.04%
New York                            1.16%
Pennsylvania                        1.16%
Virginia                            1.03%     

     The Investment  Advisory  Agreement provides that the Advisor may later, to
the extent  permitted  by law,  recapture  any fees it  deferred  or expenses it
assumed  during  the two prior  years;  provided,  however,  that  Total  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 more 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. In
addition to the compensation itemized above (sales charge and Rule 12b-1 service
and distribution  fees),  certain  broker/dealers  and/or their salespersons may
receive certain  compensation for the sale and distribution of the securities or
for services to the Fund. See the Statement of Additional  Information,  "Method
of Distribution".

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 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  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
        

     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. 
    

        
     Yield  measures  the current  investment  performance,
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
series  according to accounting  methods that are standardized for all stock and
bond funds.     

Taxable Equivalent Yield

         
     A Fund may  advertise its "taxable  equivalent  yield."
The taxable  equivalent  yield is the yield that you would be required to obtain
from taxable  investments to equal the yield of the Fund,  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 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 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.  Total return is
based on historical results and is not intended to indicate future performance.
    

    
      Total return  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 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  returns  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.

     *Payments will be made less redemptions.  For either choice,  quarterly
trailing  commissions will begin in the thirteenth month. 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  twelve  months of the time of
purchase.     

         
     Sales  charges on Fund 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 Fund  shares  held in  accounts
maintained by that firm.     

    
     Distribution Plan     

         
     Each Fund has adopted 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 Fund
shares,  to pay expenses  associated with the distribution and servicing of Fund
shares. Amounts paid by the Funds to CDI under the 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 1996 fiscal period, the Funds paid no Distribution Plan expenses.     

        

    
Arrangements with Broker-Dealers and Others     

     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.

with the same  name(s),  address  and  taxpayer  identification  number  as your
existing Calvert account.

Controller*         Initial Investment

     *Please  allow  sufficient  time for Calvert  Group to process your initial
request for this service,  normally 10 business  days.  The maximum  transaction
amount is  $300,000,  and your  purchase  request  must be received by 4:00 p.m.
Eastern time.

NET ASSET VALUE

How share price is determined.

         
     Net  asset  value  ("NAV")  refers to the  worth of one  share.  NAV is
computed  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.

         
     All of your purchases  must be made in U.S.  dollars and checks must be
drawn on U.S.  banks.  No cash will be accepted.  The 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 is not paid,  your purchase will be canceled and
you will be charged a $10 fee plus costs incurred by the Fund. When you purchase
by check or with Calvert Money Controller, those funds will be on hold for up to
10 business days from the date of receipt.  During that period,  the proceeds of
redemptions  against  those  funds  will be held  until  the  transfer  agent is
reasonably satisfied that the purchase payment has been collected. To avoid this
collection  period,  you can wire federal funds from your bank, which may charge
you a fee. As a  convenience,  check  purchases  can be  received  at  Calvert's
offices for overnight  mail delivery to the transfer  agent and will be credited
the next business day. Any check purchase  received  without an investment  slip
may cause delayed crediting.     

     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

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

         
     If your  investment  goals  change,  the  Calvert  Group 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:
    
     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     
     You may exchange shares on which you have already paid a sales charge
at  Calvert  Group  and  shares   acquired  by   reinvestment  of  dividends  or
distributions  into another fund at no additional charge. You may exchange Class
C shares  for  shares of another  fund,  but you will have to pay the  front-end
sales charge, if applicable.     

         
     For  purposes of the exchange  privilege  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  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 more information.     

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 while saving paper postage expense.     

         
     If you have multiple  accounts with Calvert,  you may receive  combined
mailings  of  some  shareholder  information,  such  as  statements,   confirms,
prospectuses,  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.

heavy market volume, or otherwise,  you may send a written redemption request to

addresses and taxpayer  identification number, unless previously authorized with
a signature-guaranteed letter. See "Exchanges."

     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 the 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 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     

     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.

Other Circumstances
         
     There is no sales charge on shares of any fund of the Calvert  Group of
Funds sold to (i)  Directors,  Trustees,  Officers,  Advisory  Council  Members,
employees of the Calvert  Group of Funds or affiliated  companies,  employees of
broker dealers  distributing  the Fund's shares and family members of the above,
(ii)  Purchases  made  through a  Registered  Investment  Advisor,  (iii)  Trust
departments of banks or savings  institutions  for trust clients of such bank or
institution, (iv) Purchases through a broker maintaining an omnibus account with
the Fund 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 First  Variable Rate Fund Calvert  First  Government
Money Market Fund (the  "Fund")  Prospectus,  dated April 30, 1997,  which
may be  obtained  free of charge by  writing  or  calling  the Fund at the
telephone numbers listed above.
    

==========================================================================
                    INVESTMENT OBJECTIVE AND STRATEGY
==========================================================================

         In pursuing its objective of earning the highest  possible  yield
consistent with safety,  liquidity,  and preservation of capital, the Fund
invests  solely in debt  obligations  issued or  guaranteed  by the United
States,  its  agencies or  instrumentalities,  assignments  of interest in
such  obligations,  and  commitments to purchase such  obligations  ("U.S.
Government-backed   obligations").   The   Fund   may   invest   in   U.S.
Government-backed   obligations  subject  to  repurchase  agreements  with
recognized securities dealers and banks.
         The Fund  engages  in  repurchase  Agreements  in order to earn a
higher  rate of  return  than it could  earn  simply by  investing  in the
obligation  which is the subject of the repurchase  agreement.  Repurchase
agreements  are not,  however,  without risk. If the seller were to become
bankrupt,  the Fund  might  realize a loss if the value of the  underlying
security  did not  equal  or  exceed  the  repurchase  price.  In order to
minimize  the  risk  of  investing  in  repurchase  agreements,  the  Fund
engages in such transactions only with recognized  securities  dealers and
banks  and in all  instances  holds  underlying  securities  with a  value
equal to the total  repurchase  price  such  dealer or bank has  agreed to
pay.  Repurchase  agreements  are always for periods of less than one year
and no more than 10% of the Fund's  assets may be invested  in  repurchase
agreements not terminable within seven days.
         Although   all  the   securities   purchased   by  the  Fund  are
Government-backed  as to principal or secured by such securities,  some of
the  types  of  Government  securities  the  Fund  buys  may be  sold at a
premium  which is not backed by a Government  guarantee.  The premiums are
amortized  over the life of the security;  however,  if a security  should
default or be prepaid,  the Fund could  realize as a loss the  unamortized
portion of such premium.
         In the  Government-guaranteed  loan market, most purchases of new
issues are made under firm (forward) commitment  agreements.  Purchases of
long-term  fixed rate debt  securities  under such  agreements can involve
risk of loss due to changes in the market  rate of  interest  between  the
commitment date and the settlement  date.  Forward  commitment  agreements
for  variable  rate  securities,  unlike  such  agreements  for fixed rate
securities,  are stable in value;  the Fund's Advisor believes the risk of
loss  under  forward   commitment   agreements   involving  variable  rate
obligations to be insignificant.
         All the Fund's  investments  maturing  in more than one year will
have  a  variable   rate  feature   under  which  the  yield  is  adjusted
periodically  based  upon  changes  in money  market  rates such as prime.
Such  adjustments  will be  made at  least  semi-annually.  Variable  rate
securities   minimize  the  wide   fluctuations   in  capital  value  that
represent the  traditional  drawback to such  long-term  investments;  but
this also means that should  interest rates decline,  the amount of return
paid by the Fund will  decline  and the Fund will  forego the  opportunity
of capital appreciation on its portfolio securities.
         The foregoing  objective and policies may not be altered  without
the  prior  approval  of the  holders  of a  majority  of the  outstanding
shares of the Fund.  There is, of course,  no assurance that the Fund will
be successful in meeting the above investment objective.

==========================================================================
                         INVESTMENT RESTRICTIONS
==========================================================================

   
         The Fund has adopted the following  investment  restrictions  and
fundamental  policies.  These  restrictions  cannot be changed without the
approval  of the holders of a majority  of the  outstanding  shares of the
Fund. The Fund may not:
         (1) Purchase common stocks,  preferred stocks, warrants,
         other equity securities,  corporate bonds or debentures,
         state bonds,  municipal  bonds,  or  industrial  revenue
         bonds;
         (2)  Borrow  money,  except  from  banks as a  temporary
         measure for emergency  (not  leveraging)  purposes in an
         amount not  greater  than 25% of the value of the Fund's
         total  assets  (including  the amount  borrowed)  at the
         time the borrowing is made.  Investment  securities will
         not  be  purchased  while  borrowings  are  outstanding.
         Borrowings  will only be undertaken  to  facilitate  the
         meeting of redemption requests;
         (3) Pledge its assets,  except to secure  borrowing  for
         temporary  or  emergency  purposes  and then  only in an
         amount up to 25% of its total assets.  Although the Fund
         has the  right to  pledge  in excess of 10% of the value
         of  its  assets,  it  will  not  do  so as a  matter  of
         operating  policy in order to comply with certain  state
         investment restrictions;
         (4) Sell securities short;
         (5) Write or purchase put or call options;
         (6) Underwrite the securities of other issuers;
         (7)  Purchase  a  security  which is subject to legal or
         contractual  restrictions  on resale,  i.e.,  restricted
         securities;
         (8)  Purchase  or  sell  real  estate  investment  trust
         securities, commodities, or oil and gas interests;
         (9)  Make  loans  to  others,   except  for   repurchase
         transactions  (the  purchase  of a portion  of  publicly
         distributed   debt  securities  is  not  considered  the
         making of a loan);
         (10) Invest in companies  for the purpose of  exercising
         control;   or   invest  in  the   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  deferred
         compensation plan.
    

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

         Dividends  from the Fund's  net  investment  income are  declared
daily and paid monthly.  Net  investment  income  consists of the interest
income  earned on  investments  (adjusted  for  amortization  of  original
issue  or  market  discount  or  premium),  less  expenses.  Realized  and
unrealized  gains and losses are not  included in net  investment  income.
Net  short-term   capital  gains  will  be  distributed  once  each  year,
although  the Fund may  distribute  them more  frequently  if necessary in
order  to  maintain  the  Fund's  net  asset  value at  $1.00  per  share.
Distributions  of net capital  gains,  if any, are  normally  declared and
paid by the Fund once a year;  however,  the Fund does not  intend to make
any such  distributions  from  securities  profits  unless  available loss
carryovers, if any, have been used or have expired.
         Purchasers  of Fund shares  begin  receiving  dividends  from the
date  federal  funds  are  received  by the Fund.  Purchases  by bank wire
received  by the  Fund's  custodian  prior to 12:30  p.m.,  Eastern  time,
represent  immediately  available  federal funds.  Shareholders  redeeming
shares by telephone,  electronic  funds  transfer or written  request will
receive  dividends  through  the  date  that  the  redemption  request  is
received;  shareholders  redeeming shares by draft will receive  dividends
up to the date such draft is presented to the Fund for payment.

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

   
         In 1996,  the Fund did qualify and in 1997,  the Fund  intends to
qualify as a  "regulated  investment  company"  under  Subchapter M of the
Internal  Revenue Code, as amended.  By so  qualifying,  the Fund will not
be  subject  to  federal  income  taxes,  nor to the  federal  excise  tax
imposed by the Tax Reform Act of 1986,  to the extent that it  distributes
its net investment income and net capital gains.
    
         Dividends  of net  investment  income  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.  Net
long-term   capital  gain   distributions,   if  any,  will  generally  be
includable as long-term  capital gain in the gross income of  shareholders
who  are  citizens  or  residents  of  the  United  States.  Whether  such
realized  securities  gains and losses are long-or  short-term  depends on
the period the  securities  are held by the Fund, not the period for which
the shareholder holds shares of the Fund.
         The  Fund  is  required  to   withhold   31%  of  any   dividends
(including  long-term  capital  gain  dividends,   if  any)  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 Internal Revenue Code because of  underreporting;  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 of dividends withheld.
         Shareholders    exempt   from   backup    withholding    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 backup
withholding  but,  along with  certain  foreign  partnerships  and foreign
corporations,  may instead be subject to  withholding  under  section 1441
of  the  Internal  Revenue  Code.  Shareholders  claiming  exemption  from
backup withholding should call or write the Fund for further information.
         Many  states  do not  tax the  portion  of the  Fund's  dividends
which is derived from  interest on U.S.  Government  obligations.  The law
of the states varies  concerning the tax status of dividends  derived from
U.S.  Government  obligations.  Accordingly,  shareholders  should consult
their tax  advisors  about the tax status of dividends  and  distributions
from the Fund in their respective jurisdictions.

==========================================================================
                             NET ASSET VALUE
==========================================================================

         The net asset  value  per  share of the Fund,  the price at which
shares are continuously  issued and redeemed,  is computed by dividing the
value of the  Fund's  total  assets,  less its  liabilities,  by the total
number  of  shares  outstanding.  Net  asset  value  is  determined  every
business  day at the  close of the New  York  Stock  Exchange  (generally,
4:00 p.m.  Eastern  time),  and at such other times as may be  appropriate
or  necessary.  The Fund 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.
         The Fund's  assets,  including  securities  subject to repurchase
agreements,  are normally  valued at their  amortized  cost which does not
take into  account  unrealized  capital  gains or  losses.  This  involves
valuing  an  instrument  at its cost and  thereafter  assuming  a constant
amortization  to maturity of any  discount or premium,  regardless  of the
impact  of  fluctuating   interest  rates  on  the  market  value  of  the
instrument.  While this method  provides  certainty in  valuation,  it may
result in periods  during which value,  as determined  by amortized  cost,
is higher or lower  than the price  that  would be  received  upon sale of
the  instrument.  During periods of declining  interest  rates,  the daily
yield  on  shares  of  the  Fund  may  tend  to  be  higher  than  a  like
computation made by a fund with identical  investments  utilizing a method
of valuation  based upon market  prices and estimates of market prices for
all of its portfolio  instruments.  Thus, if the use of amortized  cost by
the Fund  resulted in a lower  aggregate  portfolio  value on a particular
day,  a  prospective  investor  in the  Fund  would  be able to  obtain  a
somewhat  higher  yield  than  would  result  from  investment  in a  fund
utilizing solely market values,  and existing  investors in the Fund would
receive less  investment  income.  The converse would apply in a period of
rising interest rates.
         Rule 2a-7 under the  Investment  Company Act of 1940  permits the
Fund to  value  its  assets  at  amortized  cost if the Fund  maintains  a
dollar-weighted  average  maturity  of 90 days or less and only  purchases
obligations  having  remaining  maturities of 13 months or less. Rule 2a-7
further  requires,  as a condition  of its use,  that the Fund invest only
in  obligations  determined  by the  Trustees to be of high  quality  with
minimal  credit risks and  requires  the Trustees to establish  procedures
designed  to  stabilize,  to the extent  reasonably  possible,  the Fund's
price per share as computed  for the purpose of sales and  redemptions  at
$1.00. Such procedures  include review of the Fund's  investment  holdings
by the  Trustees,  at such  intervals  as they  may deem  appropriate,  to
determine   whether  the  Fund's  net  asset  value  calculated  by  using
available  market  quotations  or  equivalents  deviates  from  $1.00  per
share.  If such  deviation  exceeds l/2 of 1%, the Trustees  will promptly
consider  what  action,  if  any,  will be  initiated.  In the  event  the
Trustees  determine  that a deviation  exists which may result in material
dilution or other unfair  results to  investors or existing  shareholders,
the  Trustees  will  take  such  corrective   action  as  they  regard  as
necessary and appropriate,  including:  the sale of portfolio  instruments
prior to  maturity  to  realize  capital  gains or  losses  or to  shorten
average  portfolio  maturity;  the  withholding of dividends or payment of
distributions  from  capital or capital  gains;  redemptions  of shares in
kind;  or the  establishment  of a net asset  value per share  based  upon
available market quotations.

                           CALCULATION OF YIELD
==========================================================================

         Yield is  calculated  by  dividing  the net change  exclusive  of
capital  changes in the value of a share during a  particular  base period
by the net asset  value  per share at the  beginning  of such  period  and
annualizing the result.  Capital changes  excluded from the calculation of
yield are:  (1)  realized  gains and losses  from the sale of  securities,
and (2) unrealized  appreciation  and  depreciation.  The Fund's effective
yield for a seven-day  period is its annualized  compounded  average yield
during the period, calculated according to the following formula:

          Effective yield = [(base period return + 1)365/7] - 1

   
For the seven day period ended  December  31,  1996,  the Fund's yield was
4.74% and effective yield was 4.86%.
         The Fund's  yield  fluctuates  in response to changes in interest
rates  and  general  economic  conditions,  portfolio  quality,  portfolio
maturity,  and  operating  expenses.  Yield is not  fixed or  insured  and
therefore is not  comparable  to a savings or other  similar type account.
Yield  during any  particular  time  period  should not be  considered  an
indication  of future yield.  It is,  however,  useful in  evaluating  the
Fund's performance in meeting its investment objective.

         The Fund or its affiliates may provide  information  such as, but
not limited to, the economy,  investment climate,  investment  principles,
sociological  conditions  and political  ambiance.  Discussion may include
hypothetical  scenarios or lists of relevant  factors  designed to aid the

investor's  goals.  The Fund may list portfolio  holdings or give examples
or  securities  that may have been  considered  for inclusion in the Fund,
whether held or not.
         The Fund or its  affiliates  may supply  comparative  performance

Journal,  and  Schabacker  Investment   Management,   Inc.  Such  averages
generally  do not reflect any front- or back-end  sales  charges  that may
be  charged  by Funds  in that  grouping.  The  Fund may also  cite to any
source,  whether  in  print or  on-line,  such as  Bloomberg,  in order to
acknowledge  origin of  information.  The Fund may  compare  itself or its
portfolio  holdings  to  other  investments,  whether  or  not  issued  or
regulated  by the  securities  industry,  including,  but not  limited to,
certificates  of deposit and Treasury  notes.  The Fund, its Advisor,  and
its  affiliates  reserve the right to update  performance  rankings as new
rankings become available.

                    PURCHASES AND REDEMPTION OF SHARES
==========================================================================

         Share  certificates  will  not  be  issued  unless  requested  in
writing  by the  investor.  No charge  will be made for share  certificate
requests.  No  certificates  will be issued  for  fractional  shares  (see
Prospectus, "How to Sell Your Shares").
         Shareholders  wishing  to use the draft  writing  service  should
complete the  signature  card enclosed  with the  Investment  Application.
The draft  writing  service  will be  subject to the  customary  rules and
regulations  governing checking accounts,  and the Fund reserves the right
to change or suspend  the  service.  Generally,  there is no charge to you
for the  maintenance  of this service or the clearance of drafts,  but the
Fund  reserves  the right to charge a service fee for drafts  returned for
uncollected  or  insufficient   funds,   and  will  charge  $25  for  stop
payments.  As a  service  to  shareholders,  the  Fund  may  automatically
transfer the dollar  amount  necessary to cover drafts you have written on
the  Fund to  your  Fund  account  from  any  other  of  your  identically
registered  accounts  in Calvert  money  market  funds or Calvert  Insured
Plus. The Fund may charge a fee for this service.
         When a payable  through  draft is presented to the  Custodian for
payment,  a  sufficient  number  of full and  fractional  shares  from the
shareholder's  account to cover the  amount of the draft will be  redeemed
at the net asset value next determined.  If there are insufficient  shares
in  the  shareholder's   account,  the  draft  may  be  returned.   Drafts
presented  for  payment  which  would  require  the  redemption  of shares
purchased by check or  electronic  funds  transfer  within the previous 10
business days may not be honored.
         Existing  shareholders  who at any time desire to arrange for the
telephone redemption  procedure,  or to change instructions already given,
must send a written  notice to Calvert  Group,  P.O.  Box  419544,  Kansas
City,  MO  64141-6544,  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 credit union. 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.

         1  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  named  trustees  and  officers is a 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  and Silby are  among the  Trustees,  Acacia
Capital  Corporation,  of which  only  Messrs.  Blatz,  Diehl and Pugh are
among the  Directors,  Calvert  World  Values  Fund,  Inc.,  of which only
Messrs.  Guffey and Silby are among the  Directors,  and Calvert New World
Fund,  Inc.,  of  which  only Mr.  Martini  is among  the  Directors.  The
address  of  Trustees  and  Officers,  unless  otherwise  noted,  is  4550
Montgomery Avenue,  Suite 1000N,  Bethesda,  Maryland 20814.  Trustees and
Officers  as a  group  own  less  than 1% of the  Portfolio's  outstanding
shares.
         The  Board's  Audit  Committee  is  composed  of  Messrs.  Baird,
Blatz,  Feldman,  Guffey and Pugh.  The  Investment  Policy  Committee  is
composed of Messrs. Borts, Diehl, Gavian, Rochat and Silby.
         During  fiscal  1996,  trustees of the Fund not  affiliated  with
the  Fund's   Advisor  were  paid  $24,721.   Trustees  of  the  Fund  not
affiliated  with the  Advisor  presently  receive an annual fee of $20,500
for service as a member of the Board of  Trustees of the Calvert  Group of
Funds,  and a fee of $750 to $1500  for each  regular  Board or  Committee
meeting  attended;  such fees are allocated among the respective  Funds on
the basis of net assets.
         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  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.
         The Advisory  Contract (the "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 Board of  Trustees  of the
Fund;  and  further  provided  that  such  continuance  is  also  approved
annually  by the vote of a majority  of the  Trustees  of the Fund who are
not  parties  to  the  Contract,  interested  persons  of  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 upon 60 days'  prior

assets,  0.40% of the next $400 million of such assets,  0.35% of the next

broker-dealers  in  consideration of their  promotional or  administrative
services for Class O shares.  The Fund pays all other operating  expenses,
including   custodial  and  transfer   agency  fees,   federal  and  state
securities   registration  fees,  legal  and  audit  fees,  and  brokerage
commissions  and other  costs  associated  with the  purchase  and sale of
portfolio  securities.  However,  the Advisor has agreed to reimburse  the
Fund  for  all  expenses  (excluding  brokerage,   taxes,   interest,  and
extraordinary  items)  exceeding,  on a pro rata  basis,  1% of the Fund's
average daily net assets.
         The  advisory  fees  paid  to  the  Advisor  under  the  Advisory
Contract  for the 1994,  1995,  and 1996  fiscal  years  were  $1,254,516,
$1,182,171, and $1,238,849,  respectively.  No expense reimbursements have
been required under the Contract.

                 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  quarterly  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.  For its fiscal years ended December 31, 1994, 1995, and
1996, the Fund paid Calvert Shareholder  Services,  Inc. fees of $509,155,
$556,450, and $561,279, respectively.
    

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

         Portfolio  transactions  are  undertaken  on the  basis  of their
desirability  from an  investment  standpoint.  Investment  decisions  and
choice of brokers  and dealers  are made by the Fund's  Advisor  under the
direction and supervision of the Fund's Board of Trustees.
         It is  intended  that all  securities  maturing  in more than one
year will be held to  maturity.  Sales of  securities  to  facilitate  the
redemption  of  Fund  shares  is  contemplated,  but  such  sales  will be
primarily  from the  short-term  instruments  in the Fund's  portfolio  on
which brokerage  charges,  if any, are minimal.  The Fund anticipates that
its portfolio  turnover rate with respect to  securities  with  maturities
in excess of one year will be no more than 5%.
         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 of sale of  portfolio  securities  with
dealers who provide it with  statistical,  research,  or other information
and services.  Although any statistical,  research,  or other  information
and  services  provided  by  dealers  may be  useful to the  Advisor,  the
dollar  value of such  information  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  broker-dealer  that provided the Fund's
Advisor with research or other services.
         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 may  compensate,  at
its expense,  such  broker-dealers  in consideration of their  promotional
and administrative services.

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

   
          Coopers & Lybrand,  L.L.P.,  has been  selected  by the Board of
Trustees to serve as independent  accountants for fiscal year 1997.  State
Street  Bank  &  Trust  Company,   N.A.,  225  Franklin  Street,   Boston,
Massachusetts  02110,  currently  serves as custodian  of the  Portfolio's
investments.  First  National Bank of Maryland,  25 South Charles  Street,
Baltimore,  Maryland  21203  also  serves as  custodian  of certain of the
Portfolio's  cash assets.  Neither  custodian has any part in deciding the
Portfolio's  investment  policies or the choice of securities  that are to
be purchased or sold for the Portfolio.

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

         The Fund is  organized as a  Massachusetts  business  trust,  and
has two series.  The first series,  Calvert First  Government Money Market
Fund,  was known as First  Variable  Rate Fund prior to September 1, 1991.
The second series is Calvert Florida  Municipal  Intermediate  Fund. Prior
to April 30, 1984, the Fund was organized as a Maryland  corporation.  The
Fund's   Declaration   of  Trust   contains  an  express   disclaimer   of
shareholder   liability  for  acts  or   obligations   of  the  Fund.  The
shareholders  of  Massachusetts   business  trust  might,  however,  under
certain  circumstances,  be held  personally  liable as  partners  for its
obligations.  The  Declaration of Trust provides for  indemnification  and
reimbursement  of  expenses  out of Fund assets for any  shareholder  held
personally  liable for  obligations of the Fund. The  Declaration of Trust
provides  that the Fund  shall,  upon  request,  assume the defense of any
claim made against any  shareholder  for any act or obligation of the Fund
and  satisfy  any  judgment  thereon.  The  Declaration  of Trust  further
provides that the Fund may maintain  appropriate  insurance  (for example,
fidelity  bonding and errors and omissions  insurance)  for the protection
of the Fund, its shareholders,  trustees,  officers,  employees and agents
to  cover  possible  tort  and  other  liabilities.  Thus,  the  risk of a
shareholder  incurring financial loss on account of shareholder  liability
is limited to  circumstances  in which both  inadequate  insurance  exists
and the Fund itself is unable to meet its obligations.
         The Fund will send its  shareholders  confirmations  of  purchase
and redemption  transactions,  as well as periodic transaction  statements
and unaudited  semi-annual and audited annual financial  statements of the
Fund's  investment   securities,   assets  and  liabilities,   income  and
expenses, and changes in net assets.
         The Prospectus  and this  Statement of Additional  Information do
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.

                              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.

                            INVESTMENT RESTRICTIONS

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     
            
Each Fund imposes  reduced sales  charges for Fund 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. 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 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  series.  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.  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 returns) 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 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  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[(a-b/cd +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, 1996 is as follows:

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 and Silby.     
         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  $20,500  for  service  as a member  of the Board of
Directors/Trustees  of the  Calvert  Group of Funds plus a fee of $750 to $1,500
for each Board and Committee  meeting  attended;  such fees are allocated  among
the Funds on the basis of their net  assets.  For the 1996  fiscal  period,  the
Funds paid  director/trustee  fees of $279, $501, $1,205,  $600, $635, $444, and
$1,190, 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  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.
         The  Investment  Advisory  Agreement  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 Funds,  or by the  directors/trustees  of the Funds;  and  further  provided
that such  continuance  is also  approved  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 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.  For
the  1996  fiscal  period,  the  Advisor  received  advisory  fees  of  $16,538,
$30,771,  $72,423,  $36,078,  $38,381,  $27,180,  and $72,322,  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 1994 and 1995  fiscal  periods.  For the 1996
fiscal period,  Calvert  Administrative  Services Company received an annual fee
of $2,756,  $5,128,  $12,071,  $6,013,  $6,397, $4,530, $12,054 for the Arizona,
Florida,  Maryland,  Michigan, New York, Pennsylvania,  and Virginia Portfolios,
respectively.     

                             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 1994,  1995, and 1996 fiscal periods,  the Fund paid
no  Distribution  Plan  expenses.  In 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.  For
fiscal 1996, CDI received  sales charges in excess of the dealer  reallowance of
$1,262,  $849,  $4,214,  $670,  $1,977,  $1,228,  and $9,039,  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,  0.15% of the Funds' average daily
net  assets.  As of October  1,  1998,  expenses  may not  exceed,  on an annual
basis, 0.25% of the Funds' average daily net assets.     
         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.  Any change in the
Plans  that  would  materially  increase  the  distribution  cost  to the  Funds
requires  approval of the shareholders;  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.  ("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  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.  In fiscal  1994,  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  Virginia   Portfolios,
respectively.  For  the  1995  fiscal  period,  CSSI  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.  For
the 1996 fiscal period, CSSI received $2,759,  $2,162,  $9,807,  $4,739, $7,183,
$3,841,  and $8,953, 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 1997.  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.
            
In fiscal 1994,  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.  For the 1996 fiscal period,  the portfolio turnover was 18%, 19%,
8%, 18%,  19%, 9%, and 4%, 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.  Upon any
liquidation  of the Funds,  shareholders  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.

                              FINANCIAL STATEMENTS

            
The audited  financial  statements in the Funds' Annual Report to  Shareholders,
dated  December 31, 1996,  are  expressly  incorporated  by reference and made a
part of this  Statement of Additional  Information.  A copy of the Annual Report
may be obtained free of charge by writing or calling the Funds.     

                                    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.


                                LETTER OF INTENT

Date                       

Calvert Distributors, Inc.
4550 Montgomery Avenue
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*) 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:

         __ $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.

Item 27.  Indemnification

1 of this Registration Statement, provides, in summary, that officers,
trustees, employees, and agents shall be indemnified by Registrant
against liabilities and expenses incurred by such persons in connection
with actions, suits, or proceedings arising out of their offices or
duties of employment, except that no indemnification can be made to such
a person if he has been adjudged liable of willful misfeasance, bad
faith, gross negligence, or reckless disregard of his duties.  In the
absence of such an adjudication, the determination of eligibility for
indemnification shall be made by independent counsel in a written
opinion or by the vote of a majority of a quorum of trustees who are
neither "interested persons" of Registrant, as that term is defined in
Section 2(a)(19) of the Investment Company Act of 1940, nor parties to
the proceeding.

         Registrant's Declaration of Trust also provides that Registrant
may purchase and maintain liability insurance on behalf of any officer,
trustee, employee or agent against any liabilities arising from such
status.  In this regard, Registrant maintains a Directors & Officers
(Partners) Liability Insurance Policy with Chubb Group of Insurance
Companies, 15 Mountain View Road, Warren, New Jersey  07061, providing
Registrant with $5 million in directors and officers liability coverage,
plus $3 million in excess directors and officers liability coverage for
the independent trustees/directors only.  Registrant also maintains a $9
million Investment Company Blanket Bond issued by ICI Mutual Insurance
Company, P.O. Box 730, Burlington, Vermont, 05402, and an additional $5
million in excess of $9 million blanket bond with Chubb Group of
Insurance Companies, 15 Mountain View Road, Warren, New Jersey  07061.

                  File numbers 2-56809 and 811-2633


Ladies and Gentlemen:

         As counsel to Calvert Group, Ltd., it is my opinion that the
securities being registered by this Post-Effective Amendment No. 34 will
be legally issued, fully paid and non-assessable when sold.  My opinion
is based on an examination of documents related to First Variable Rate
Fund for Government Income (the "Trust"), including its Declaration of
Trust, its By-Laws, other original or photostatic copies of Trust
records, certificates of public officials, documents, papers, statutes,
and 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 Trust's
Post-Effective Amendment No. 34 to its Registration Statement.

                                             Sincerely,



                                             /s/Ivy Wafford Duke
