The Calvert Social Money Market Portfolio (formerly,
Calvert Responsibly Invested Money Market Portfolio)

The Portfolio invests in money market instruments,
including repurchase agreements with banks and brokers
secured by money market instruments, and seeks to
maintain a constant net asset value of $1.00 per share.
An investment in the Portfolio is neither insured nor

INVESTMENT OBJECTIVE AND POLICIES
The investment objective described below is fundamental
and may not be changed without the approval of the
holders of a majority of the outstanding shares of the
Portfolio. As a Policyholder, you may be given an
opportunity to indicate how you believe the Insurance
Company should vote the shares which underlie your
Policy.

The investment objective of the Portfolio is to provide
current income by investing in enterprises that make a
significant contribution to society through their
products and services and through the way they do
business. The Portfolio aims for short-term cash
management and stability of principal. The Portfolio
seeks to provide the highest level of current income,
consistent with liquidity, safety and security of
capital, by investing in money market instruments,
including repurchase agreements with recognized
securities dealers and banks secured by such
instruments, selected in accordance with its investment
and social criteria. The Portfolio attempts to maintain
a constant net asset value of $1.00 per share.

The Portfolio invests only in high grade, short-term
money market instruments which may include: obligations
issued or guaranteed as to principal by the United
States Government, its agencies and instrumentalities;
U.S. dollar-denominated certificates of deposit, time
deposits and bankers' acceptances of U.S. banks,
generally banks with assets in excess of $1 billion; and
commercial paper (including participation interests in
loans extended by banks to issuers of commercial paper)
that at the date of investment is rated A-1 by Standard
& Poor's Corporation or Prime-1 by Moody's Investors
Service, Inc., or, if not rated, is of comparable
quality.

 ..........................................................

ADDITIONAL FUNDAMENTAL INVESTMENT POLICIES
The Portfolio may engage in repurchase agreements and
reverse repurchase agreements. In a repurchase
agreement, the Portfolio buys a security subject to the
right and obligation to sell it back at a higher price.
In order to minimize any risk involved, the Portfolio
engages in such transactions only with recognized
securities dealers and banks determined by the Advisor
to present a minimal credit risk. Repurchase agreements
are fully collateralized and always have a maturity of
less than one year. No more than 10 percent of Portfolio
assets may be invested in repurchase agreements not
terminable within seven days. In a reverse repurchase
agreement, the Portfolio sells a security subject to the
right and obligation to buy it back at a higher price.
The Portfolio then invests the proceeds from the
transaction in another obligation in which it is
authorized to invest. For reverse repurchase agreements,
the Portfolio maintains a segregated account with liquid
assets equal in value to the repurchase price.

The Portfolio may borrow money from banks (and pledge
its assets to secure such borrowing) for temporary or
emergency purposes, but not for leverage. This type of
borrowing may not exceed 10% of the value of the
Portfolio's total assets. The Portfolio may also make
loans of the securities it holds. The advantage of
loaning securities is that the Portfolio continues to
receive the equivalent of the interest earned or
dividends paid by the issuers while at the same time
earning interest on the cash or equivalent collateral
that may be invested in accordance with the Portfolio's
investment objective, policies, and restrictions. The
purpose of the loans is usually to facilitate the
delivery of securities. As with any extension of credit,
there may be risks of delay in recovery and possible
loss of rights in the loaned security if the borrower
fails financially. The Investment Advisor attempts to
reduce the risk by lending only to borrowers that it
deems creditworthy and only on terms that it believes
compensates for any risk inherent in the transaction.

The Portfolio may lend its securities to New York Stock
Exchange member firms and to commercial banks with
assets of one billion dollars or more. All loans must be
secured continuously in the form of cash or cash
equivalents such as U.S. Treasury bills. In addition,
the amount of collateral must, on a current basis, equal
or exceed the market value of the loaned securities, and
the Portfolio may only make the loan if the value of the
securities loaned does not exceed 10% of its assets. The
Portfolio must be able to terminate loans at any time
with appropriate notice. The Portfolio will exercise its
right to terminate a securities loan in order to
preserve its right to vote on matters of importance
affecting holders of the securities. All securities must
be returned to the Portfolio when a loan terminates, and
the Portfolio absorbs any gain or loss in the market
value of the securities during the loan period.

   
The Portfolio may invest up to 25% of its assets in the
securities of foreign issuers, provided it purchases
only high quality, U.S. dollar-denominated instruments.
    

 ..........................................................

   
ADDITIONAL NONFUNDAMENTAL INVESTMENT POLICIES
The Portfolio has adopted the following operating (i.e.,
nonfundamental) investment policies which may be changed
by the Board of Directors without shareholder approval:
    

The Portfolio may not purchase illiquid securities if
more than 10% of the value of its net assets would be
invested in such securities. Further, the Portfolio may
not acquire private placement investments until the
value of the Portfolio's assets exceeds $20 million.

For further information on the Portfolio's investment
policies and restrictions, as well as a description of
the types of securities that may be purchased, see the
Statement of Additional Information.

 ..........................................................

                    INVESTMENT SCREENS
- ----------------------------------------------------------

Each investment is selected with a concern for its
social impact. The Portfolio invests in accordance with
its philosophy that long-term rewards to investors will
come from those organizations whose products, services,
and methods enhance the human condition and the
traditional American values of individual initiative,
equality of opportunity and cooperative effort.

The Portfolio has developed the following criteria for
the selection of organizations in which they invest. The
Portfolio recognizes, however, that these criteria
represent standards of behavior which few, if any,
organizations totally satisfy and that, as a matter of
practice, evaluation of a particular organization in the
context of these criteria will involve subjective
judgment by the Portfolio's Investment Advisor.

Given these considerations, the Portfolio seeks to
invest in producers or service providers that:

1.   Deliver safe products and services in ways that
     sustain our natural environment.

2.   Are managed with participation throughout the
     organization in defining and achieving objectives.

3.   Negotiate fairly with their workers, provide an
     environment supportive of their wellness, do not
     discriminate on the basis of race, gender,
     religion, age, disability, ethnic origin, or sexual
     orientation, do not consistently violate
     regulations of the Equal Employment Opportunity
     Commission, and provide opportunities for women,
     disadvantaged minorities, and others for whom equal
     opportunities have often been denied.

4.   Foster awareness of a commitment to human goals,
     such as creativity, productivity, self-respect and
     responsibility, within the organization and the
     world, and continually recreate a context within
     which these goals can be realized.

The Portfolio will not invest in an issuer primarily
engaged in:

1.   The production of nuclear energy or the manufacture
     of equipment to produce nuclear energy.

2.   Business activities in support of repressive
     regimes.

3.   The manufacture of weapons systems.

In addition, the Portfolio will not, as a matter of
operating policy which may be changed without the
approval of a majority of the outstanding shares, invest
in an issuer primarily engaged in the manufacture of
alcoholic beverages or tobacco products, or the
operation of gambling casinos.

   
The Portfolio believes that social and technological
change will continue to transform America and the world
into the next century. Those enterprises that exhibit a
social awareness measured in terms of the above
attributes and considerations should be better prepared
to meet future societal needs for goods and services. By
responding to social concerns, these enterprises should
maintain flexibility and further social goals. In so
doing they may not only avoid the liability that may be
incurred when a product or service is determined to have
a negative social impact or has outlived its usefulness,
but should also be better positioned to develop
opportunities to make a profitable contribution to
society. The Portfolio believes that these enterprises
will be ready to respond to external demands and ensure
that over the longer term they will be able to provide a
positive return to both investors and society as a whole.
    

In selecting investments under the four positive and
three negative factors outlined above, the Advisor will
consider the investments' ability to contribute to the
dual objective of the Portfolio. Potential investments
are first screened for financial soundness and then
evaluated according to social criteria. To the greatest
extent possible investments are made in companies
exhibiting unusual, positive accomplishments with
respect to one or more of the criteria. Companies must
meet the Portfolio's minimum standards for all the
criteria. It should be noted that the Portfolio's social
criteria tend to limit the availability of investment
opportunities more than is customary with other
investment portfolios.

The selection of an organization for investment by the
Portfolio does not constitute endorsement or validation,
nor does the exclusion of an organization necessarily
reflect failure to satisfy the Portfolio's social
criteria. Investors in the Portfolio are invited to send
brief descriptions of companies they believe might be
suitable investments.

 ..........................................................

               THE FUND AND ITS MANAGEMENT
- ----------------------------------------------------------

   
Calvert Variable Series, Inc. (the "Fund"), a Maryland
corporation, is an open-end investment company, which
was incorporated under the laws of the State of Maryland
on September 27, 1982. The Board of Directors supervises
the business affairs and investments of the Fund, which
are managed on a daily basis by the Fund's Investment
Advisor. The Fund has several investment Portfolios,
each issuing one class of stock. The shares of the Fund
currently are sold only to insurance companies
(collectively, the "Insurance Companies") for allocation
to their separate accounts (collectively, the "Variable
Accounts") to fund the benefits under certain variable
annuity and variable life insurance policies
(collectively, the "Policies") issued by such companies.
Accordingly, the interest of a policy owner in the
shares is subject to the terms of the particular annuity
or life insurance policy and is described in the
attached prospectus for one of the Policies, which
should be reviewed carefully by a person considering the
purchase of a Policy. The rights of the Insurance
Companies as shareholders should be distinguished from
the rights of a policy owner which are described in the
Policies. Policy owners should consider that the
investment return experience of the Portfolio will
affect the value of the policy and the amount of annuity
payments or life insurance benefits received under a
policy. See the attached prospectus(es) for the Policies
for a description of the relationship between increases
or decreases in the net asset value of Portfolio shares
(and any distributions on such shares) and the benefits
provided under a policy.
    

 ..........................................................

Investment Advisor

   
Calvert Asset Management Company, Inc. (the "Advisor"),
4550 Montgomery Avenue, Suite 1000N, Bethesda, Maryland
20814, is the Investment Advisor to the Portfolio.
Calvert Asset Management is a wholly-owned subsidiary of
Calvert Group, Ltd., which is in turn an indirect
wholly-owned subsidiary of Acacia Mutual Life Insurance
Company. As of December 31, 1997, Calvert Group, Ltd.
had assets under management and administration in excess
of $5.0 billion. Pursuant to its investment advisory
agreement with the Fund, the Investment Advisor manages
the investment and reinvestment of the assets of each
Portfolio and is responsible for the overall management
of the business affairs of each Portfolio, subject to
the direction and authority of the Fund's Board of
Directors.
    

 ..........................................................

Advisory Fee

   
For its services, the Advisor during 1997, received an
annual fee of 0.50% of net assets based on a percentage
of the average daily net assets of the Portfolio.
    

 ..........................................................

Expenses

   
The Portfolio's expenses, which are accrued daily,
include: the fee of the Investment Advisor; costs of
executing portfolio transactions; pricing costs;
interest; taxes; custodian and transfer agent fees;
legal and auditing fees; bookkeeping and dividend
disbursing expenses; and certain other expenses relating
to the Portfolio's operations. Certain expenses are paid
by the particular Portfolio that incurs them, while
other expenses are allocated among each Portfolio on the
basis of their relative size (based on net assets), or
as designated by the Board of Directors, as appropriate.
Expenses constituted 0.69% of the average net assets of
the Portfolio for 1997, including fees paid indirectly,
and 0.59% net of fees paid indirectly.
    

 ..........................................................

Capital Stock

   
The Fund issues separate stock for each of its
Portfolios. Shares of each of the Portfolios have equal
rights with regard to voting, redemptions, dividends,
distributions, and liquidations. No Portfolio has
preference over another Portfolio. When issued, shares
are fully paid and nonassessable and do not have
preemptive or conversion rights or cumulative voting
rights. The Insurance Companies and the Fund's
shareholders will vote Fund shares allocated to
registered separate accounts in accordance with
instructions received from policyholders. Under certain
circumstances, which are described in the accompanying
prospectus of the variable life or annuity policy, the
voting instructions received from variable life or
annuity policyholders may be disregarded.
    

 ..........................................................

            PURCHASE AND REDEMPTION OF SHARES
- ----------------------------------------------------------

The Fund offers its shares, without sales charge, only
for purchase by various Insurance Companies for
allocation to their Variable Accounts. Shares are
purchased by the Variable Accounts at the net asset
value of the Portfolio next determined after the
Insurance Company receives the premium payment. The Fund
continuously offers its shares in the Portfolio at a
price equal to the net asset value per share. Initial
and subsequent payments allocated to a Portfolio are
subject to the limits applicable in the Policies issued
by the Insurance Companies.

It is conceivable that in the future it may be
disadvantageous for both annuity Variable Accounts and
life insurance Variable Accounts, or for Variable
Accounts of different Insurance Companies, to invest
simultaneously in the Fund, although currently neither
the Insurance Companies nor the Fund foresee any such
disadvantages to either variable annuity or variable
life insurance policyholders of any Insurance Company.
The Fund's Board of Directors intends to monitor events
in order to identify any material conflict between such
policyholders and to determine what action, if any,
should be taken in response to the problem.

The Insurance Companies redeem shares of the Fund to
make benefit and surrender payments under the terms of
their Policies. Redemptions are processed on any day on
which the Fund is open for business (each day the New
York Stock Exchange is open), and are made at the
Portfolio's net asset value next determined after the
appropriate Insurance Company receives a surrender
request in acceptable form.

Payment for redeemed shares will be made promptly, and
in no event later than seven days. However, the right of
redemption may be suspended or the date of payment
postponed in accordance with the Rules under the
Investment Company Act of 1940. The Fund redeems all
full and fractional shares of the Portfolio for cash.

The net asset value of the shares of the Portfolio is
determined once daily as of the close of business of the
New York Stock Exchange, on days when the Exchange is
open for

   
business, or for any other day when there is a
sufficient degree of trading in the investments of the
Portfolio to affect materially its net asset value per
share (except on days when no orders to purchase or
redeem shares of the Portfolio have been received). The
net asset value is determined by adding the values of
all securities and other assets of the Portfolio,
subtracting liabilities and expenses, and dividing by
the number of outstanding shares of the Portfolio. All
instruments held by Calvert Social Money Market are
valued on an amortized cost basis.
    

 ..........................................................

               DIVIDENDS AND DISTRIBUTIONS
- ----------------------------------------------------------

   
It is the Portfolio's intention to distribute
substantially all of its net investment income, if any.
For dividend purposes, net investment income consists of
the interest income earned on investments, plus or minus
amortized purchase discount or premium, plus or minus
realized and unrealized gains and loss, less estimated
expenses. All net realized capital gains, if any, are
declared and distributed periodically, at least
annually. All dividends and distributions are reinvested
in additional shares of the Portfolio at net asset value.
    

 ..........................................................

                    YIELD INFORMATION
- ----------------------------------------------------------

   
From time to time Calvert Social Money Market advertises
its "yield" and "effective yield." The "yield" of the
Portfolio refers to the actual income generated by an
investment in the Portfolio over a particular base
period of time, which will be stated in the
advertisement. If the base period is less than one year,
the yield is then "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 similarly but, when
annualized, the income earned by an investment in the
Portfolio is assumed to be reinvested. The "effective
yield" will be slightly higher than the "yield'' because
of the compounding effect of this assumed reinvestment.
    


                          TAXES
- ----------------------------------------------------------

   
As a "regulated investment company" under the Internal
Revenue Code of 1986, as amended, the Fund is not
subject to federal income or excise tax to the extent
that it distributes its net investment income and net
capital gains. Each Portfolio is treated as a separate
entity for federal income tax purposes. Since the sole
shareholders of the Fund are Insurance Companies, no
discussion is included here as to the federal income tax
consequences at the shareholder level. For information
concerning the federal tax consequences to purchasers of
the annuity or life insurance policies, see the
prospectuses for the Policies.

INVESTMENT OBJECTIVE AND POLICIES

The investment objective described below is not
fundamental and may be changed upon 60 days written
notice to shareholders without a shareholder vote. There
is, of course, no assurance that the Portfolio will be
successful in meeting its objective.

The investment objective of the Portfolio is to provide
long-term capital appreciation by investing primarily in
equity securities of companies that have small market
capitalizations. In seeking capital appreciation, the
Portfolio invests primarily in equity securities of
small capitalized growth companies that have
historically exhibited exceptional growth
characteristics and that, in the Advisor's opinion, have
strong earnings potential relative to the U.S. market as
a whole. The Portfolio's investment objective is not
fundamental and may be changed without shareholder
approval.

The Portfolio pursues the objective of capital
appreciation by investing primarily in equity securities
of primarily small companies with promising growth
potential. These companies typically are developing
innovative products or services to seize emerging
opportunities.

Under normal circumstances, the Portfolio will invest at
least 65% of its total assets in equity securities of
companies publicly traded in the United States
(currently those with a total market capitalization of
under $1 billion at the time of the Portfolio's initial
investment).

The Portfolio considers issuers of all industries with
operations in all geographic markets, and does not seek
interest income or dividends. Equity securities may
include common stocks, preferred stocks, convertible
securities and warrants. The Portfolio may hold cash or
cash equivalents for temporary defensive purposes or to
enable it to take advantage of buying opportunities.
There is, of course, no assurance that the Portfolio
will be successful in meeting its objective.

Companies whose capitalization increases or decreases
after initial purchase by the Portfolio continue to be
considered small-capitalized for purposes of the 65%
policy. Accordingly, less than 65% of the Portfolio's
total assets may be invested in securities of issuers of
companies publicly traded in the United States
(currently those with a total market capitalization of
less than $1 billion).

The Portfolio will normally be as fully invested as
practicable in common stocks (including ADRs), but also
may invest in warrants and rights to purchase common
stocks and in debt securities and preferred stocks
convertible into common stocks (collectively, "equity
securities").

While any investment in securities carries a certain
degree of risk, the approach of the Portfolio is
designed to maximize growth in relation to the risks
assumed. The securities of small cap issuers may be less
actively traded than the securities of larger issuers,
may trade in a more limited volume, and may change in
value more abruptly than securities of larger companies.
Information concerning these securities may not be
readily available so that the companies may be less
actively followed by stock analysts. Small-cap issuers
do not usually participate in market rallies to the same
extent as more widely-known securities, and they tend to
have a relatively higher percentage of insider ownership.

Investing in smaller, new issuers generally involves
greater risk than investing in larger, established
issuers. Companies in which the Portfolio is likely to
invest may have limited product lines, markets or
financial resources and may lack management depth. The
securities in such companies may also have limited
marketability and may be subject to more abrupt or
erratic market movements than securities of larger, more
established companies or the market averages in general.
Accordingly an investment in the Portfolio may not be
appropriate for all investors.

Although the Portfolio invests primarily in equity
securities, it may invest up to 35% of its assets in
debt securities, excluding money market instruments.
These debt securities may consist of investment-grade
and noninvestment-grade 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).
Noninvestment-grade securities are those rated below Baa
or BBB, or unrated obligations that the investment
subadvisor has determined are not investment-grade; such
securities have speculative characteristics. The
Portfolio will not buy debt securities rated lower than
C. See "Additional Risk Factors - Noninvestment-grade
Securities."

Under normal market conditions the Portfolio strives to
be fully invested in securities. However, for temporary
defensive purposes - which may include a lack of
adequate purchase candidates or an unfavorable market
environment - the Portfolio may invest up to 35% of its
total assets in cash or cash equivalents. Cash
equivalents include instruments such as, but not limited
to, U.S. government and agency obligations, certificates
of deposit, bankers' acceptances, time deposits,
commercial paper, short-term corporate debt securities
and repurchase agreements.

 ..........................................................

ADDITIONAL FUNDAMENTAL INVESTMENT POLICIES
In extraordinary circumstances, the Portfolio may use
options and futures contracts 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 Portfolio can use
these practices only as protection against an adverse
move of the holdings in the Portfolio to adjust the risk
and return characteristics of the Portfolio. The
decision to invest in these instruments will be based on
market conditions, regulatory limits and tax
considerations. If market conditions are judged
incorrectly, a strategy does not correlate well with the
Portfolio'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 the Portfolio 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 Portfolio's limitation on
illiquid securities. See below and the Statement of
Additional Information for more details about these
strategies.

There can be no assurance that engaging in options,
futures, or any other investment strategy will be
successful. While defensive strategies are designed to
protect the Portfolio from potential declines, if market
values or other economic factors are misgauged, the
Portfolio may be worse off than had it not employed the
defensive strategy. While an attempt is made to assess
market and equity risk and thereby prevent declines in
the value of the Portfolio's portfolio holdings, there
is a risk of imperfect or no correlation between price
movements of portfolio investments and instruments used
as part of an investment strategy, so that a loss may be
incurred. While such strategies can reduce the risk of
loss, they can also reduce the opportunity for gain
since they can or may offset favorable price movements.
The use of these strategies may result in a disadvantage
to the Portfolio if the Portfolio is not able to
purchase or sell a portfolio holding at an optimal time
due to the need to cover its transaction in its
segregated account, or due to the inability of the
Portfolio to liquidate its position because of its
relative illiquidity.

The Portfolio may engage in repurchase agreements and
reverse repurchase agreements. In a repurchase
agreement, the Portfolio buys a security subject to the
right and obligation to sell it back at a higher price.
In order to minimize any risk involved, the Portfolio
engages in such transactions only with recognized
securities dealers and banks determined by the Advisor
to present a minimal credit risk. Repurchase agreements
are fully collateralized and always have a maturity of
less than one year. Repurchase agreements not terminable
within seven days are considered illiquid. In a reverse
repurchase agreement, the Portfolio sells a security
subject to the right and obligation to buy it back at a
higher price. The Portfolio then invests the proceeds
from the transaction in another obligation in which it
is authorized to invest. For reverse repurchase
agreements, the Portfolio maintains a segregated account
with liquid assets equal in value to the repurchase
price.

The Portfolio may borrow money from banks (and pledge
its assets to secure such borrowing) for temporary or
emergency purposes, but not for leverage. This type of
borrowing may not exceed one-third of the value of the
Portfolio's total assets. The Portfolio may also make
loans of the securities it holds. The advantage of
loaning securities is that the Portfolio continues to
receive the equivalent of the interest earned or
dividends paid by the issuers while at the same time
earning interest on the cash or equivalent collateral
that may be invested in accordance with the Portfolio's
investment objective, policies, and restrictions. The
purpose of the loans is usually to facilitate the
delivery of securities. As with any extension of credit,
there may be risks of delay in recovery and possible
loss of rights in the loaned security if the borrower
fails financially. The Investment Advisor attempts to
reduce the risk by lending only to borrowers that it
deems creditworthy and only on terms that it believes
compensates for any risk inherent in the transaction.

The Portfolio may lend its portfolio securities to
member firms of the New York Stock Exchange and
commercial banks with assets of one billion dollars or
more, although it does not currently intend to lend more
than 5% of its portfolio securities. The advantage of
such loans is that the Portfolio continues to receive
the equivalent of the interest earned or dividends paid
by the issuers on the loaned securities while at the
same time earning interest on the cash or equivalent
collateral which may be invested in accordance with the
Portfolio's investment objective, policies and
restrictions. As with any extension of credit, there may
be risks of delay in recovery and possibly loss of
rights in the loaned securities should the borrower of
the loaned securities fail financially.

 ..........................................................

ADRS
The Portfolio may invest up to 15% of its total assets
in ADRs which are traded in the U.S. on exchanges or
over the counter and are generally sponsored and issued
by domestic banks. ADRs represent the right to receive
securities of foreign issuers deposited in a domestic
bank or a correspondent bank. ADRs do not eliminate all
the risk inherent in investing in the securities of
foreign issuers. However, by investing in ADRs rather
than directly in foreign issuers' stock, the Portfolio
may avoid currency risks during the settlement period
for either purchases or sales. In general, there is a
large, liquid market in the U.S. for many ADRs. The
information available for ADRs is subject to the
accounting, auditing and financial reporting standards
of the domestic market or exchange on which they are
traded, which standards are more uniform and more
exacting than those to which many foreign issuers may be
subject.

 ..........................................................

ADDITIONAL NONFUNDAMENTAL INVESTMENT POLICIES
Small Cap has adopted the following operating (i.e.,
nonfundamental) investment policies which may be changed
by the Board of Directors without shareholder approval:

The Portfolio may not purchase illiquid securities if
more than 15% of the value of its net assets would be
invested in such securities. Further, the Portfolio may
not acquire private placement investments until the
value of its assets exceeds $20 million.

For further information on the Portfolio's investment
policies and restrictions, as well as a description of
the types of securities that may be purchased, see the
Statement of Additional Information.

 ..........................................................

ADDITIONAL RISK FACTORS
Interest Rate Risk

All fixed income instruments are subject to
interest-rate risk: that is, if 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 will be.

 ..........................................................

Noninvestment-grade Securities

Noninvestment-grade securities tend to be less sensitive
to interest rate changes than higher-rated investments,
but are more sensitive to adverse economic changes and
individual corporate developments. This may affect the
issuer's ability to make principal and interest payments
on the debt obligation. There is also a greater risk 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, it may be difficult for the
Portfolio to sell the securities. Because of a lack of
objective data, a thinly-traded market may make it
difficult to value the securities, so that the Board of
Directors may have to exercise its judgment in assigning
a value. See the Appendix in the Statement of Additional
Information for more information on bond ratings.

 ..........................................................

Real Estate Investment Trusts

The Portfolio also may invest in real estate investment
trusts ("REITs"), including equity REITs, which own real
estate properties, and mortgage REITs, which make
construction, development and long-term mortgage loans.
The risks associated with REITs include default by
borrowers, self-liquidation, failure to qualify as a
pass-through entity under the Federal tax law, failure
to qualify as an exempt entity under the 1940 Act, and
the fact that REITs are not diversified.

Investment screens
- ----------------------------------------------------------
Once equity and debt securities are determined to fall
within the investment objective of the Portfolio and are
deemed financially viable investments, they are screened
according to the social criteria described below. These
social screens are applied to potential investment
candidates by the Advisor in consultation with the
Subadvisor. However, the Portfolio may purchase
instruments used for defensive purposes, such as short
positions, options and futures contracts, without regard
to the social criteria. The following criteria may be
changed by the Fund's Board of Directors without
shareholder approval:

1.   The Portfolio avoids investing in companies that,
     in the Advisor's opinion, have significant or
     historical patterns of violating environmental
     regulations, or otherwise have an egregious
     environmental record. Additionally, the Portfolio
     will avoid investing in nuclear power plant
     operators and owners, or manufacturers of key
     components in the nuclear power process.

2.   The Portfolio will not invest in companies that are
     listed among the top 100 weapons systems
     contractors, or major nuclear weapons systems
     contractors.

3.   The Portfolio will not invest in companies that, in
     the Advisor's opinion, have significant or
     historical patterns of discrimination against
     employees on the basis of race, gender, religion,
     age, disability or sexual orientation, or in
     companies that have major labor-management disputes.

4.   The Portfolio will not invest in companies that are
     significantly involved in the manufacture of
     tobacco or alcohol products. The Portfolio will not
     invest in companies that make products or offer
     services that, under proper use, in the Advisor's
     opinion, are considered harmful.

While the Portfolio may invest in companies that exhibit
positive social characteristics, it makes no explicit
claims to seek out companies with such practices.

 ..........................................................

               THE FUND AND ITS MANAGEMENT
- ----------------------------------------------------------

Calvert Variable Series, Inc. (the "Fund"), a Maryland
corporation, is an open-end investment company, which
was incorporated under the laws of the State of Maryland
on September 27, 1982. The Board of Directors supervises
the business affairs and investments of the Fund, which
are managed on a daily basis by the Fund's Investment
Advisor. The Fund has several investment Portfolios,
each issuing one class of stock. The shares of the Fund
currently are sold only to insurance companies
(collectively, the "Insurance Companies") for allocation
to their separate accounts (collectively, the "Variable
Accounts") to fund the benefits under certain variable
annuity and variable life insurance policies
(collectively, the "Policies") issued by such companies.
Accordingly, the interest of a policy owner in the
shares is subject to the terms of the particular annuity
or life insurance policy and is described in the
attached prospectus for one of the Policies, which
should be reviewed carefully by a person considering the
purchase of a Policy. The rights of the Insurance
Companies as shareholders should be distinguished from
the rights of a policy owner which are described in the
Policies. Policy owners should consider that the
investment return experience of the Portfolio will
affect the value of the policy and the amount of annuity
payments or life insurance benefits received under a
policy. See the attached prospectus(es) for the Policies
for a description of the relationship between increases
or decreases in the net asset value of Portfolio shares
(and any distributions on such shares) and the benefits
provided under a policy.

 ..........................................................

Investment Advisor and Subadvisor

Calvert Asset Management Company, Inc. (the "Advisor"),
4550 Montgomery Avenue, Suite 1000N, Bethesda, Maryland
20814, is the Investment Advisor to all of the Fund's
Portfolios. It is a wholly-owned subsidiary of Calvert
Group, Ltd., which is in turn an indirect wholly-owned
subsidiary of Acacia Mutual Life Insurance Company. As
of December 31, 1997, Calvert Group, Ltd. had assets
under management and administration in excess of $5.0
billion. Pursuant to its investment advisory agreement
with the Fund, the Investment Advisor manages the
investment and reinvestment of the assets of each
Portfolio and is responsible for the overall management
of the business affairs of each Portfolio, subject to
the direction and authority of the Fund's Board of
Directors. The Advisor has retained an investment
subadvisor ("Subadvisor") for Small Cap. The Advisor
will continuously monitor and evaluate the performance
and investment style of the Subadvisor.

   
The Subadvisor to the Portfolio is Awad & Associates
("AWAD"). AWAD is located at 477 Madison Avenue, New
York, New York 10022. AWAD had $960 million in assets
under management as of December 31, 1997. The Subadvisor
manages the investment and reinvestment of the assets of
the Portfolio, although the Advisor may screen potential
investments for compatibility with the Portfolio's
social criteria.
    

The Portfolio will be managed by a team of investment
professionals. The Senior Investment Officer is James D.
Awad. Mr. Awad has been in the investment business since
1965, focusing on research and portfolio management.
Prior to forming AWAD, he was founder and President of
BMI Capital, a successful money management firm. In
addition, he has managed assets at Neuberger & Berman,
Channing Management and First Investment Corp. Mr. Awad
earned an MBA from Harvard Business School and a BS Cum
Laude from Washington & Lee University.

Dennison T. Veru is President of AWAD. Mr. Veru joined
AWAD in 1992 coming from Smith Barney Harris Upham where
he was Senior Vice President of the firm's Whiffletree
Capital Management division specializing in small and
medium capitalization stocks. From 1988 through 1990, he
was a Vice President of Broad Street Investment
Management. Prior to that, he was an Assistant Vice
President at Drexel Burnham Lambert. Mr. Veru is a
graduate of Franklin and Marshall College.

AWAD also manages the Calvert New Vision Small Cap Fund,
a series of The Calvert Fund, an open-end investment
company sponsored by Calvert Group, Ltd.

The Portfolio has obtained an exemptive order from the
Securities and Exchange Commission to permit the
Portfolio, pursuant to approval by the Board of
Trustees, to enter into and materially amend contracts
with the Portfolio's Subadvisor without shareholder
approval. See "Investment Advisory Agreement" in the SAI
for further details.



Advisory Fee

   
Effective December 1, 1997, the Investment Advisor
received from the Portfolio a monthly base fee, computed
on a daily basis at an annual rate of 0.90% of the
average daily net assets of the Portfolio.

Prior to December 1, 1997, the Investment Advisor
received from the Portfolio a monthly base fee, computed
on a daily basis at an annual rate of 1.50% of the
average daily net assets of the Portfolio, plus a
performance fee. The performance fee was terminated
December 1997.

Effective October 1, 1997, the Advisor paid the
Subadvisor a base fee of 0.40% of the Portfolio's
average daily net assets.

Prior to October 1, 1997, the Advisor paid the previous
Subadvisor a base fee of 0.95% of the Portfolio's
average net assets.
    

 ..........................................................

Administrative Services

   
Calvert Administrative Services Company ("CASC"), an
affiliate of the Advisor, has been retained by Small Cap
to provide certain administrative services necessary to
the conduct of its affairs, including the preparation of
regulatory filings and shareholder reports, the daily
determination of net asset value per share and
dividends, and the maintenance of portfolio and general
accounting records. For providing such services, CASC is
entitled to receive a fee from the Portfolio of 0.10% of
net assets per year. For the period January through
November 1997, the fee was based on 0.20% of the
Portfolio's annual average net assets. Effective
December 1997, the annual fee was changed to 0.10%.
    

 ..........................................................

Expenses

   
The Portfolio's expenses, which are accrued daily,
include: the fee of the Investment Advisor; costs of
executing portfolio transactions; pricing costs;
interest; taxes; custodian and transfer agent fees;
legal and auditing fees; bookkeeping and dividend
disbursing expenses; and certain other expenses relating
to the Fund's operations. Certain expenses are paid by
the particular Portfolio that incurs them, while other
expenses are allocated among each Portfolio on the basis
of their relative size (based on net assets), or as
designated by the Board of Directors, as appropriate.
Expenses constituted 1.92%, annualized, of the average
net assets of the Portfolio for 1997, including fees
paid indirectly, and 1.61%, annualized, net of fees paid
indirectly.
    

 ..........................................................

Capital Stock

   
The Fund issues separate stock for each of its
Portfolios. Shares of each of the Portfolios have equal
rights with regard to voting, redemptions, dividends,
distributions, and liquidations. No Portfolio has
preference over another Portfolio. When issued, shares
are fully paid and nonassessable and do not have
preemptive or conversion rights or cumulative voting
rights. The Insurance Companies and the Fund's
shareholders will vote Fund shares allocated to
registered separate accounts in accordance with
instructions received from policyholders. Aegon
Financial Services Group, Inc. (formerly, Providian Life
and Health Insurance Company) owns more than 25% of the
outstanding stock of the Portfolio. Under certain
circumstances, which are described in the accompanying
prospectus of the variable life or annuity policy, the
voting instructions received from variable life or
annuity policyholders may be disregarded.
    

 ..........................................................

            PURCHASE AND REDEMPTION OF SHARES
- ----------------------------------------------------------

The Fund offers its shares, without sales charge, only
for purchase by various Insurance Companies for
allocation to their Variable Accounts. Shares are
purchased by the Variable Accounts at the net asset
value of the Portfolio next determined after the
Insurance Company receives the premium payment. The Fund
continuously offers its shares in the Portfolio at a
price equal to the net asset value per share. Initial
and subsequent payments allocated to the Portfolio are
subject to the limits applicable in the Policies issued
by the Insurance Companies.

It is conceivable that in the future it may be
disadvantageous for both annuity Variable Accounts and
life insurance Variable Accounts, or for Variable
Accounts of different Insurance Companies, to invest
simultaneously in the Fund, although currently neither
the Insurance Companies nor the Fund foresee any such
disadvantages to either variable annuity or variable
life insurance policyholders of any Insurance Company.
The Fund's Board of Directors intends to monitor events
in order to identify any material conflict between such
policyholders and to determine what action, if any,
should be taken in response to the problem.

The Insurance Companies redeem shares of the Fund to
make benefit and surrender payments under the terms of
their Policies. Redemptions are processed on any day on
which the Fund is open for business (each day the New
York Stock Exchange is open), and are made at the
Portfolio's net asset value next determined after the
appropriate Insurance Company receives a surrender
request in acceptable form.

Payment for redeemed shares will be made promptly, and
in no event later than seven days. However, the right of
redemption may be suspended or the date of payment
postponed in accordance with the Rules under the
Investment Company Act of 1940. The amount received on
redemption of the shares of the Portfolio may be more or
less than the amount paid for the shares, depending on
the fluctuations in the market value of the assets owned
by the Portfolio. The Fund redeems all full and
fractional shares of each Portfolio for cash.

The net asset value of the shares of each Portfolio of
the Fund is determined once daily as of the close of
business of the New York Stock Exchange, on days when
the Exchange is open for business, or for any other day
when there is a sufficient degree of trading in the
investments of the Portfolio to affect materially its
net asset value per share (except on days when no orders
to purchase or redeem shares of the Portfolio have been
received). The net asset value is determined by adding
the values of all securities and other assets of the
Portfolio, subtracting liabilities and expenses, and
dividing by the number of outstanding shares of the
Portfolio.

Except for money market instruments maturing in 60 days
or less, securities held by the Portfolio are valued at
their market value if market quotations are readily
available. Otherwise, securities are valued at fair
value as determined in good faith by the Board of
Directors, although the actual calculations may be made
by persons acting pursuant to the direction of the
Board. Money market instruments with a remaining
maturity of 60 days or less held by the Portfolio are
valued on an amortized cost basis.

 ..........................................................

               DIVIDENDS AND DISTRIBUTIONS
- ----------------------------------------------------------

It is the Portfolio's intention to distribute
substantially all of its net investment income, if any.
For dividend purposes, net investment income consists of
all payments of dividends or interest received by the
Portfolio less estimated expenses, including the
investment advisory fee. All net realized capital gains,
if any, are declared and distributed periodically, at
least annually. All dividends and distributions are
reinvested in additional shares of the Portfolio at net
asset value. No dividends will accrue on amounts
represented by uncashed distribution or redemption
checks.

 ..........................................................

                 TOTAL RETURN INFORMATION
- ----------------------------------------------------------

Total Return and Other Quotations

Small Cap may advertise "total return." Total return
refers to the total change in value of an investment in
the Portfolio over a specified period. It differs from
yield in that yield figures measure only the income
component of the Portfolio's investments, while 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 its
overall change in value, including changes in share
price and assuming all of the Portfolio's dividends and
capital gain distributions are reinvested. A cumulative
total return reflects the Portfolio's performance over a
stated period of time. An average annual total return
reflects the hypothetical annual compounded return that
would have produced the same cumulative total return if
the Portfolio's performance had been constant over the
entire period. Because average annual returns tend to
smooth out variations in the Portfolio's returns, you
should recognize that they are not the same as actual
year-by-year results. The total return of the Portfolio
generally does not include the effect of paying the
charges or expenses on the particular insurance policy
or annuity contract for which the Portfolio serves as
the investment vehicle.

 ..........................................................

                          TAXES
- ----------------------------------------------------------

As a "regulated investment company" under the Internal
Revenue Code of 1986, as amended, the Fund is not
subject to federal income or excise tax to the extent
that it distributes its net investment income and net
capital gains. Each Portfolio is treated as a separate
entity for federal income tax purposes. Since the sole
shareholders of the Fund are Insurance Companies, no
discussion is included here as to the federal income tax
consequences at the shareholder level. For information
concerning the federal tax consequences to purchasers of
the annuity or life insurance policies, see the
prospectuses for the Policies.

          TRANSFER AND DIVIDEND DISBURSING AGENT
- ----------------------------------------------------------

Calvert Shareholder Services, Inc., 4550 Montgomery
Avenue, Suite 1000N, Bethesda, Maryland 20814, is the
shareholder servicing agent. National Financial Data
Services, Inc. ("NFDS"), has been retained by the Fund
to act as transfer agent and dividend disbursing agent.

INVESTMENT OBJECTIVE AND POLICIES

   
Calvert Social Mid Cap Growth seeks to provide long-term
capital appreciation by investing primarily in a
nondiversified portfolio of the equity securities of
mid-sized companies that are undervalued but demonstrate
a potential for growth. The Portfolio will rely on its
proprietary research to identify stocks that may have
been overlooked by analysts, investors, and the media,
and which generally have a market capitalization within
the range of the S&P 500 Mid-Cap Index, but which may be
larger or smaller as deemed appropriate. Investments may
also include, but are not limited to, preferred stocks,
foreign securities, convertible securities, bonds, notes
and other debt securities. The Portfolio may use certain
futures and options, invest in repurchase agreements,
and lend its portfolio securities. The Portfolio will
take reasonable risks in seeking to achieve its
investment objective. There is, of course, no assurance
that the Portfolio will be successful in meeting its
objective since there is risk involved in the ownership
of all equity securities. The Portfolio's investment
objective is not fundamental and may be changed without
shareholder approval. The Portfolio will notify
shareholders at least thirty days in advance of a change
in the investment objective of the Portfolio so that
shareholders may determine whether the Portfolio's goals
continue to meet their own.
    

Under normal market conditions the Portfolio strives to
be fully invested in securities. However, for temporary
defensive purposes - which may include a lack of
adequate purchase candidates or an unfavorable market
environment - the Portfolio may invest up to 100% of its
assets in cash or cash equivalents. Cash equivalents
include instruments such as, but not limited to, U.S.
government and agency obligations, certificates of
deposit, bankers' acceptances, time deposits, commercial
paper, short-term corporate debt securities and
repurchase agreements.

Although the Portfolio invests primarily in equity
securities, it may invest in debt securities. These debt
securities may consist of investment-grade and
noninvestment-grade 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).
Noninvestment-grade securities are those rated below Baa
or BBB, or unrated obligations that the investment
subadvisor has determined are not investment-grade; such
securities are speculative, and the Portfolio currently
intends to limit such investments to 5% of its assets.
The Portfolio will not buy debt securities rated lower
than C. See "Additional Risk Factors -
Noninvestment-grade Securities."

   
Calvert Social Mid Cap Growth may, in pursuit of its
investment objectives, purchase put and call options and
engage in the writing of covered call options and
secured put options on securities of issuers that meet
the Portfolio's social criteria, and employ a variety of
other investment techniques, including the purchase and
sale of market index futures contracts, financial
futures contracts and options on such futures. Investing
in options may involve a greater degree of risk than
those inherent in more conservative investment
approaches. The Portfolio will engage in futures
contracts and related options only to protect against
market declines. The Portfolio will not engage in such
transactions for speculation or leverage. It is an
operating policy of the Fund that no Portfolio may
invest in exchange-traded put and call options if as a
result more than 5% of its assets would be so invested.
    

The Portfolio may invest up to 25% of its assets in
foreign securities. There are substantial and different
risks involved in investing in foreign securities. You
should consider these risks carefully. For example,
there is generally less publicly available information
about foreign companies than is available about
companies in the U.S. Foreign companies are generally
not subject to uniform audit and financial reporting
standards, practices, and requirements comparable to
those in the U.S.

   
For many foreign securities, there are U.S.
dollar-denominated American Depositary Receipts
("ADRs"), which are traded in the U.S. on exchanges or
over the counter and are generally sponsored and issued
by domestic banks. ADRs represent the right to receive
securities of foreign issuers deposited in a domestic
bank or a correspondent bank. ADRs do not eliminate all
the risk inherent in investing in the securities of
foreign issuers. However, by investing in ADRs rather
than directly in foreign issuers' stock, the Portfolio
may avoid currency risks during the settlement period
for either purchases or sales. In general, there is a
large, liquid market in the U.S. for many ADRs. The
information available for ADRs is subject to the
accounting, auditing and financial reporting standards
of the domestic market or exchange on which they are
traded, which standards are more uniform and more
exacting than those to which many foreign issuers may be
subject. The Portfolio may also invest in European
Depositary Receipts ("EDRs"), which are receipts
evidencing an arrangement with a European bank similar
to that for ADRs and are designed for use in the
European securities markets. EDRs are not necessarily
denominated in the currency of the underlying security.
The dividends and interest payable on certain of the
Portfolio's foreign securities may be subject to foreign
withholding taxes, thus reducing the net amount
available for distribution to the Portfolio's
shareholders.
    

Repurchase agreements are arrangements under which the
Portfolio buys securities and the seller simultaneously
agrees to repurchase the securities at a specified time
and price. The Portfolio may engage in repurchase
agreements 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. In order to
minimize the risk of investing in repurchase agreements,
the Portfolio may engage 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 the dealer or bank has
agreed to pay. Repurchase agreements are always for
periods of less than one year, and are considered
illiquid if not terminable within seven days.

The Portfolio may lend its portfolio securities to
member firms of the New York Stock Exchange and
commercial banks with assets of one billion dollars or
more, provided the value of the securities loaned from
the Portfolio will not exceed 10% of the Portfolio's
assets. Any such loans must be secured continuously in
the form of cash or cash equivalents such as U.S.
Treasury bills; the amount of the collateral must on a
current basis equal or exceed the market value of the
loaned securities, and the Portfolio must be able to
terminate such loans upon notice at any time. The
Portfolio will exercise its right to terminate a
securities loan in order to preserve its right to vote
on matters of importance affecting holders of the
securities.

The advantage of such loans is that the Portfolio
continues to receive the equivalent of the interest
earned or dividends paid by the issuers on the loaned
securities while at the same time earning interest on
the cash or equivalent collateral which may be invested
in accordance with the Portfolio's investment objective,
policies and restrictions.

Securities loans are usually made to broker-dealers and
other financial institutions to facilitate their
delivery of such securities. As with any extension of
credit, there may be risks of delay in recovery and
possible loss of rights in the loaned securities should
the borrower of the loaned securities fail financially.
However, the Portfolio will make loans of its portfolio
securities only to those firms the Advisor deems
creditworthy and only on such terms the Advisor believes
should compensate for such risk. On termination of the
loan the borrower is obligated to return the securities
to the Portfolio. The Portfolio will realize any gain or
loss in the market value of the securities during the
loan period. The Portfolio may pay reasonable custodial
fees in connection with the loan.

The Portfolio seeks to achieve its stated objectives by
following the investment policies established for that
purpose. The investment returns and degrees of market
and financial risk depend on the types of investments
the Portfolio undertakes to make as established by its
policies. Policies that are designated fundamental may
not be changed without the approval of the holders of a
majority of the outstanding shares of each portfolio
affected by the proposed change. As a Policyholder, you
may be given an opportunity to indicate how you believe
the Insurance Company should vote the shares underlying
your Policy.

 ..........................................................

ADDITIONAL RISK FACTORS
Nondiversified Portfolio

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


Interest Rate Risk

All fixed income instruments are subject to
interest-rate risk: that is, if 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 will be.

 ..........................................................

Small-Cap Stocks

   
The Portfolio may purchase the securities of small-cap
issuers. The securities of small-cap issuers tend to be
less actively traded than the securities of larger
issuers, may trade in a more limited volume, and may
change in value more abruptly than securities of larger
companies. Information concerning these securities may
not be readily available so that the companies may be
less actively followed by stock analysts. Small-cap
issuers do not usually participate in market rallies to
the same extent as more widely-known securities, and
they tend to have a relatively higher percentage of
insider ownership. There is no limit on the percentage
of assets that may be invested in small-cap issuers.
    

 ..........................................................

Noninvestment-grade Securities

Noninvestment-grade securities tend to be less sensitive
to interest rate changes than higher-rated investments,
but are more sensitive to adverse economic changes and
individual corporate developments. This may affect the
issuer's ability to make principal and interest payments
on the debt obligation. There is also a greater risk 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, it may be difficult for the
Portfolio to sell the securities. Because of a lack of
objective data, a thinly-traded market may make it
difficult to value the securities, so that the Board of
Directors may have to exercise its judgment in assigning
a value. See the Appendix in the Statement of Additional
Information for more information on bond ratings.

   
Calvert Social Mid Cap Growth Portfolio's fixed-income
investment strategies caused it to have a relatively
high portfolio turnover compared to other portfolios. A
portfolio with high turnover may incur higher
transaction costs, such as custodian and settlement
fees. During fiscal 1997, brokerage commission expenses
remained relatively level even though turnover increased
significantly, since the fixed-income investments are
traded on a spread, rather than a commission basis.
    

 ..........................................................

                    INVESTMENT SCREENS
- ----------------------------------------------------------

Once securities are determined to fall within the
investment objective of the Portfolio and are deemed
financially viable investments, they are screened
according to the social criteria described below. These
social screens are applied to potential investment
candidates by the Advisor in consultation with the
Subadvisor.

The following criteria may be changed by the Portfolio's
Board of Directors without shareholder approval:

1.   The Portfolio avoids investing in companies that,
     in the Advisor's opinion, have significant or
     historical patterns of violating environmental
     regulations, or otherwise have an egregious
     environmental record. Additionally, the Portfolio
     will avoid investing in nuclear power plant
     operators and owners, or manufacturers of key
     components in the nuclear power process.

2.   The Portfolio will not invest in companies that are
     significantly engaged in weapons production. This
     includes weapons systems contractors and major
     nuclear weapons systems contractors.

3.   The Portfolio will not invest in companies that, in
     the Advisor's opinion, have significant or
     historical patterns of discrimination against
     employees on the basis of race, gender, religion,
     age, disability or sexual orientation, or that have
     major labor-management disputes.

4.   The Portfolio will not invest in companies that are
     significantly involved in the manufacture of
     tobacco or alcohol products. The Portfolio will not
     invest in companies that make products or offer
     services that, under proper use, in the Advisor's
     opinion, are considered harmful.

The Advisor will seek to review companies' overseas
operations consistent with the social criteria stated
above. While the Portfolio may invest in companies that
exhibit positive social characteristics, it makes no
explicit claims to seek out companies with such
practices.

               THE FUND AND ITS MANAGEMENT
- ----------------------------------------------------------

Calvert Variable Series, Inc. (the "Fund") is an
open-end management investment company registered under
the Investment Company Act of 1940, as amended. The Fund
was incorporated under the laws of the State of Maryland
on September 27, 1982. Calvert Social Mid Cap Growth is
one of the Fund's portfolios, and is designed to provide
opportunities for investing in enterprises that make a
significant contribution to society through their
products and services and through the way they do
business. Shares of the Portfolio are sold only to
insurance companies (collectively, the "Insurance
Companies") for allocation to their separate accounts to
fund the benefits under certain variable annuity and
variable life insurance policies (collectively, the
"Policies").

Shares of the Portfolio may only be sold to Insurance
Companies for their separate accounts, and not to
individual investors. As such, the "shareholders"
referred to in this prospectus are the Insurance
Companies. The Insurance Companies' prospectuses explain
the relationship between changes in the net asset value
of the Portfolio's shares and the benefits provided
under a policy. The prospectuses also detail your
interests as a policyholder in the shares of the
separate account and your ability to determine the type
of investment underlying the Policy. You should
carefully review the appropriate prospectus when you
consider buying a Policy.

The Fund has several other portfolios or series, which
are sold to other insurance companies to fund the
benefits under certain variable annuity and variable
life insurance policies issued by the insurance
companies. The Board of Directors supervises the
business affairs and investments of the Portfolio, which
is managed on a daily basis by the Investment Advisor.

 ..........................................................

Investment Advisor

   
Calvert Asset Management Company, Inc. (the"Advisor"),
4550 Montgomery Avenue, Suite 1000N, Bethesda, Maryland
20814, is the Investment Advisor to the Portfolio. It is
a wholly-owned subsidiary of Calvert Group, Ltd., which
is in turn an indirect wholly-owned subsidiary of Acacia
Mutual Life Insurance Company. As of December 31, 1997,
Calvert Group, Ltd. had assets under management and
administration in excess of $5.0 billion. Pursuant to
its investment advisory agreement with the Fund, the
Investment Advisor manages the investment and
reinvestment of the assets of the Portfolio and is
responsible for the overall management of the business
affairs of the Portfolio, subject to the direction and
authority of the Fund's Board of Directors.
    

 ..........................................................

Subadvisor

   
Brown Capital Management, Inc. of Baltimore, Maryland is
the subadvisor to the Portfolio. Brown Capital
Management believes that capital can be enhanced in
times of opportunity and preserved in times of adversity
without timing the market. The firm uses a bottom-up
approach that incorporates growth-adjusted price
earnings. Stocks purchased are generally undervalued and
have momentum, have earnings per share growth rates
greater than the market, are more profitable than the
market, and have relatively low price-earnings ratios. A
team of experienced investment managers manage the
Portfolio.
    



Mr. Brown is founder and President of Brown Capital
Management. He has over 22 years of investment
experience, having served as a Vice President and
Portfolio Manager for 10 years at T. Rowe Price
Associates immediately prior to starting his own firm.
Mr. Brown holds an M.S. in Business Administration from
the Indiana University School of Business. Additionally,
he is a professionally-designated Chartered Financial
Analyst ("CFA") and Chartered Investment Counselor.

Mr. Oppenheim has had 25 years' investment experience
for institutions, including the State of Maryland, T.
Rowe Price Associates, Inc., the National Rural Electric
Pension and Brown Capital Management. He holds a B.S. in
Economics and Juris Doctor from the University of
Wisconsin, and is a CFA.

Mr. Hall has over 30 years' investment experience
including 18 years with T. Rowe Price Associates, Inc.,
seven years with Emerging Growth Partners, Inc., and
four years with The Investment Center, prior to joining
Brown Capital Management. Mr. Hall is a former Trustee
of the Peabody Institute of Johns Hopkins University.

 ..........................................................

Advisory Fee

   
For fiscal year 1997, the Advisor received from the
Portfolio a base fee of 0.80% of the average daily net
assets of the Portfolio. From this base fee, the Advisor
pays the Subadvisor a base fee of 0.25% of average net
assets. In addition, under the circumstances described
below, the Advisor and the Subadvisor may earn (or have
their fees reduced by) performance fee adjustments based
on the extent to which performance of the Portfolio
exceeds or trails the index against which it is
measured. The performance fee adjustment began February
1997. The specific adjustments are as follows, and are
calculated monthly:

*The Index is a blend of 60% of the Russell 1000 Growth
Index and 40% of the Russell 2000 Index.
    

Payment of an upward performance fee adjustment will be
from the Portfolio to the Advisor, and the Advisor will
pass on the appropriate amount to the Subadvisor; fees
adjusted downward from the base fee as a result of
under-performance will be retained by the Portfolio.
Payment of an upward performance adjustment will be
conditioned on: (1) the performance of the Portfolio as
a whole having exceeded the S&P 400 Mid-Cap Index; and
(2) payment of the performance adjustment not causing
the Portfolio's performance to fall below the S&P 400
Mid-Cap Index.

Calvert Administrative Services Company ("CASC"), an
affiliate of the Advisor, has been retained by the
Portfolio to provide certain administrative services
necessary to the conduct of its affairs, including the
preparation of regulatory filings and shareholder
reports, the daily determination of net asset value per
share and dividends, and the maintenance of portfolio
and general accounting records. For providing such
services, CASC is entitled to receive a fee from the
Portfolio of 0.10% of net assets per year.

 ..........................................................

Expenses

   
The Advisor provides the Fund with investment
supervision and management; certain administrative
services and office space; furnishes executive and other
personnel to the Fund; and pays the salaries and fees of
all Directors who are affiliated persons of the Advisor.
The Advisor may also assume and pay certain advertising
and promotional expenses of the Funds and reserves the
right to compensate broker-dealers in return for their
promotional or administrative services. The Fund pays
all other operating expenses, including the fee of the
Investment Advisor; costs of executing portfolio
transactions; pricing costs; interest; taxes; custodian
and transfer agent fees; legal and auditing fees;
bookkeeping and dividend disbursing expenses; and
certain other expenses relating to operations. Certain
expenses are paid by the Portfolio, while other expenses
are allocated among the various portfolios of the Fund
on the basis of their relative size (based on net
assets), or as designated by the Board of Directors, as
appropriate. Expenses constituted 1.04% of the average
net assets of the Portfolio for 1997, including fees
paid indirectly, and 0.96% net of fee paid indirectly.
    

 ..........................................................

Capital Stock

   
The Fund issues separate shares of stock for each of its
Portfolios. Shares of each of the Portfolios have equal
rights with regard to voting, redemptions, dividends,
distributions, and liquidations. No Portfolio has
preference over another Portfolio. When issued, shares
are fully paid and nonassessable and do not have
preemptive or conversion rights or cumulative voting
rights. The Insurance Companies will vote Portfolio
shares allocated to registered separate accounts in
accordance with instructions received from
policyholders. Shares for which the Portfolio does not
receive voting instructions will be voted in proportion
to shares for which it has already received votes. Aegon
Financial Services Group, Inc. (formerly, Providian Life
and Health Insurance Company) owns more than 25% of the
outstanding stock of the Portfolio. Under certain
circumstances, which are described in the accompanying
prospectus of the variable life or annuity policy, the
voting instructions received from variable life or
annuity policyholders may be disregarded.
    

 ..........................................................

            PURCHASE AND REDEMPTION OF SHARES
- ----------------------------------------------------------

The Portfolio offers its shares, without sales charge,
only for purchase by various Insurance Companies for
allocation to their Variable Accounts. Shares are
purchased by

the Variable Accounts at the net asset value of the
Portfolio next determined after the Insurance Company
receives the premium payment. The Fund continuously
offers its shares in the Portfolio at a price equal to
the net asset value per share. Initial and subsequent
payments allocated to the Portfolio are subject to the
limits applicable in the Policies issued by the
Insurance Companies.

It is conceivable that in the future it may be
disadvantageous for both annuity Variable Accounts and
life insurance Variable Accounts, or for Variable
Accounts of different Insurance Companies, to invest
simultaneously in the Portfolio, although currently
neither the Insurance Companies nor the Fund foresee any
such disadvantages to either variable annuity or
variable life insurance policyholders of any Insurance
Company. The Fund's Board of Directors intends to
monitor events in order to identify any material
conflict between such policyholders and to determine
what action, if any, should be taken in response to the
problem.
The Insurance Companies redeem shares of the Portfolio
to make benefit and surrender payments under the terms
of their Policies. Redemptions are processed on any day
on which the Fund is open for business (each day the New
York Stock Exchange is open), and are made at the
Portfolio's net asset value next determined after the
appropriate Insurance Company receives a surrender
request in acceptable form.

Payment for redeemed shares will be made promptly, and
in no event later than seven days. However, the right of
redemption may be suspended or the date of payment
postponed in accordance with the Rules under the
Investment Company Act of 1940. The amount received on
redemption of the shares of the Portfolio may be more or
less than the amount paid for the shares, depending on
the fluctuations in the market value of the assets owned
by the Portfolio. The Fund redeems all full and
fractional shares of the Portfolio for cash.

The net asset value of the shares of the Portfolio is
determined once daily as of the close of business of the
New York Stock Exchange, on days when the Exchange is
open for business, or for any other day when there is a
sufficient degree of trading in the investments of the
Portfolio to affect materially its net asset value per
share (except on days when no orders to purchase or
redeem shares of the Portfolio have been received). The
net asset value is determined by adding the values of
all securities and other assets of the Portfolio,
subtracting liabilities and expenses, and dividing by
the number of outstanding shares of the Portfolio.

Except for money market instruments maturing in 60 days
or less, securities held by the Portfolio are valued at
their market value if market quotations are readily
available. Otherwise, securities are valued at fair
value as determined in good faith by the Board of
Directors, although the actual calculations may be made
by persons acting pursuant to the direction of the Board.

 ..........................................................

               DIVIDENDS AND DISTRIBUTIONS
- ----------------------------------------------------------

It is the Fund's intention to distribute substantially
all of the net investment income, if any, of the
Portfolio. The net investment income consists of all
payments of dividends or interest received by the
Portfolio less estimated expenses, including the
investment advisory fee. All net realized capital gains,
if any, are declared and distributed periodically, at
least annually. All dividends and distributions are
reinvested in additional shares of the Portfolio at net
asset value.

 ..........................................................

                 TOTAL RETURN INFORMATION
- ----------------------------------------------------------

The Portfolio may advertise "total return." Total return
refers to the total change in value of an investment in
the Portfolio over a specified period. It includes not
only the effect of income dividends but also any change
in net asset value, or principal amount, during the
stated period. Total return shows the Portfolio's
overall change in value, including changes in share
price and assuming all of the Portfolio's dividends and
capital gain distributions are reinvested. A cumulative
total return reflects the Portfolio's performance over a
stated period of time. An average annual total return
reflects the hypothetical annual compounded return that
would have produced the same cumulative total return if
the Portfolio's performance had been constant over the
entire period. Because average annual returns tend to
smooth out variations in the Portfolio's returns, you
should recognize that they are not the same as actual
year-by-year results. The total return of the Portfolio
does not include the effect of paying the charges and
expenses on the particular insurance policy or annuity
contract for which the Portfolio serves as the
investment vehicle.

 ..........................................................

                          TAXES
- ----------------------------------------------------------

As a "regulated investment company" under the Internal
Revenue Code of 1986, as amended, the Fund is not
subject to federal income or excise tax to the extent
that it distributes its net investment income and net
capital gains. The Portfolio is treated as a separate
entity for federal income tax purposes. Since the sole
shareholders of the Fund are Insurance Companies, no
discussion is included here as to the federal income tax
consequences at the shareholder level. For information
concerning the federal tax consequences to purchasers of
the annuity or life insurance policies, see the
prospectuses for the Policies.

 ..........................................................

          TRANSFER AND DIVIDEND DISBURSING AGENT
- ----------------------------------------------------------

   
Calvert Shareholder Services, Inc., 4550 Montgomery
Avenue, Suite 1000N, Bethesda, Maryland 20814, is the
shareholder servicing agent. National Financial Data
Services, Inc. "NFDS"), has been retained by the Fund
to act as transfer agent and dividend disbursing agent.

INVESTMENT OBJECTIVE AND POLICIES
The investment objective described below is fundamental
and may not be changed without the approval of the
holders of a majority of the outstanding shares of the
Portfolio. As a Policyholder, you may be given an
opportunity to indicate how you believe the Insurance
Company should vote the shares which underlie your
Policy.

   
The investment objective of Calvert Social International
Equity is to provide a high total return consistent with
reasonable risk by investing primarily in a globally
diversified portfolio of equity securities. The
Portfolio seeks total return through a globally
diversified investment portfolio. It is designed to
provide growth of capital or current income by investing
in enterprises that make a significant contribution to
society through their products and services and through
the way they do business. All investments are screened
for financial and social criteria. The Portfolio may
engage in hedging transactions involving options,
futures contracts and foreign currency transactions to
reduce its risk exposure (see "Investment Techniques").

Under normal circumstances, Calvert Social International
Equity will invest at least 65% of its assets in equity
securities. The Portfolio will invest primarily in
common stocks of established foreign and U.S. companies
believed to have potential for capital growth, income or
both. However, it may invest in any other type of
security including, but not limited, to convertible
securities, preferred stocks, bonds, notes and other
debt securities of companies (including Euro-currency
instruments and securities), or of any international
agency (such as the Asian Development Bank or
Inter-American Development Bank) or obligations of
domestic or foreign governments and their political
subdivisions, and in foreign currency transactions. The
Portfolio may establish and maintain reserves for
temporary defensive purposes or to enable it to take
advantage of buying opportunities. Calvert Social
International Equity's reserves may be invested in
domestic as well as foreign short-term money market
instruments including, but not limited to, government
obligations, certificates of deposit, bankers'
acceptances, time deposits, commercial paper, short-term
corporate debt securities and repurchase and reverse
repurchase agreements. The Portfolio may also engage in
certain options transactions, and enter into futures
contracts and related options for hedging purposes and
lend portfolio securities. See "Additional Fundamental
Investment Policies, Risks of Foreign Securities,
Foreign Currency Transactions, and Additional
Non-Fundamental Investment Policies."

Under normal circumstances, Calvert Social International
Equity will invest at least 65% of its assets in the
securities of issuers in no less than three countries,
other than the U.S. Under normal circumstances, business
activities in a number of different foreign countries
will be represented in the Portfolio's investments. The
Portfolio may, from time to time, have more than 25% of
its assets invested in any major industrial or developed
country which in the view of the Subadvisor poses no
unique investment risk. Under exceptional economic or
market conditions, Calvert Social International Equity
may invest substantially all of its assets in only one
or two countries, or in U.S. government obligations or
securities of companies incorporated in and having their
principal activities in the U.S. As an operating policy,
the Portfolio will limit its investment in securities of
U.S. issuers, to 5% of its net assets.
    



In determining the appropriate distribution of
investments among various countries and geographic
regions, the Subadvisor ordinarily will consider the
following factors: prospects for relative economic
growth among foreign countries; expected levels of
inflation; relative price levels of the various capital
markets; government policies influencing business
conditions; the outlook for currency relationships and
the range of individual investment opportunities
available to the global investor. The Portfolio may make
investments in developing countries, which involve
exposure to economic structures that are generally less
diverse and mature than in the United States, and to
political systems which may be less stable. A developing
country can be considered to be a country which is in
the initial stages of its industrialization cycle. In
the past, markets of developing countries have been more
volatile than the markets of developed countries;
however, such markets often have provided higher
long-term rates of return to investors. The Subadvisor
believes that these characteristics can be expected to
continue in the future.

   
Generally, Calvert Social International Equity will not
trade in securities for short-term profits, but, when
circumstances warrant, securities may be sold without
regard to the length of time held. The Portfolio may
write covered call options and purchase call and put
options on securities and security indices, and may
write secured put options and enter into option
transactions on foreign currency. It may also engage in
transactions in financial futures contracts and related
options for hedging purposes, and invest in repurchase
agreements. These investment techniques and the related
risks are summarized below and are described in more
detail in the Statement of Additional Information.

Calvert Social International Equity may purchase unrated
debt instruments, if the Advisor or Subadvisor
determines they are of comparable quality to permissible
rated instruments. Although the Portfolio may invest up
to 5% of its assets in noninvestment-grade bonds (those
rated below BBB by Standard & Poor's or equivalent), it
does not intend to purchase any such bonds unless the
instrument provides an opportunity to invest in an
attractive company in which an equity investment is not
currently available or desirable. (See
"Noninvestment-grade Debt Securities.")
    

 ..........................................................

   
ADDITIONAL FUNDAMENTAL INVESTMENT POLICIES
Calvert Social International Equity may, in pursuit of
its investment objectives, purchase put and call options
and engage in the writing of covered call options and
secured put options on securities of issuers that meet
its social criteria, and employ a variety of other
investment techniques, including the purchase and sale
of market index futures contracts, financial futures
contracts and options on such futures. Investing in
options may involve a greater degree of risk than those
inherent in more conservative investment approaches. The
Portfolio will engage in futures contracts and related
options only to protect against market declines. The
Portfolio will not engage in such transactions for
speculation or leverage. It is an operating policy of
the Fund that no Portfolio may invest in options and
futures contracts if as a result more than 5% of its
assets would be so invested.
    

The Portfolio may engage in repurchase agreements and
reverse repurchase agreements. In a repurchase
agreement, the Portfolio buys a security subject to the
right and obligation to sell it back at a higher price.
In order to minimize any risk involved, the Portfolio
engages in such transactions only with recognized
securities dealers and banks determined by the Advisor
to present a minimal credit risk. Repurchase agreements
are fully collateralized and always have a maturity of
less than one year. No more than 10 percent of the
Portfolio's assets may be invested in repurchase
agreements not terminable within seven days. In a
reverse repurchase agreement, the Portfolio sells a
security subject to the right and obligation to buy it
back at a higher price. The Portfolio then invests the
proceeds from the transaction in another obligation in
which it is authorized to invest. For reverse repurchase
agreements, the Portfolio maintains a segregated account
with liquid assets equal in value to the repurchase
price.

The Portfolio may borrow money from banks (and pledge
its assets to secure such borrowing) for temporary or
emergency purposes, but not for leverage. This type of
borrowing may not exceed 10% of the value of the
Portfolio's total assets. The Portfolio may also make
loans of the securities it holds. The advantage of
loaning securities is that the Portfolio continues to
receive the equivalent of the interest earned or
dividends paid by the issuers while at the same time
earning interest on the cash or equivalent collateral
that may be invested in accordance with the Portfolio's
investment objective, policies, and restrictions. The
purpose of the loans is usually to facilitate the
delivery of securities. As with any extension of credit,
there may be risks of delay in recovery and possible
loss of rights in the loaned security if the borrower
fails financially. The Investment Advisor attempts to
reduce the risk by lending only to borrowers that it
deems creditworthy and only on terms that it believes
compensates for any risk inherent in the transaction.

The Portfolio may lend its securities to New York Stock
Exchange member firms and to commercial banks with
assets of one billion dollars or more. All loans must be
secured continuously in the form of cash or cash
equivalents such as U.S. Treasury bills. In addition,
the amount of collateral must, on a current basis, equal
or exceed the market value of the loaned securities, and
the Portfolio may only make the loan if the value of the
securities loaned does not exceed 10% of its assets. The
Portfolio must be able to terminate loans at any time
with appropriate notice. The Portfolio will exercise its
right to terminate a securities loan in order to
preserve its right to vote on matters of importance
affecting holders of the securities. All securities must
be returned to the Portfolio when a loan terminates, and
the Portfolio absorbs any gain or loss in the market
value of the securities during the loan period.


   
RISKS OF FOREIGN SECURITIES
Calvert Social International Equity may invest all of
its assets in foreign securities. There are substantial
and different risks involved in investing in foreign
securities. You should consider these risks carefully.
For example, there is generally less publicly available
information about foreign companies than is available
about companies in the U.S. Foreign companies are
generally not subject to uniform audit and financial
reporting standards, practices and requirements
comparable to those in the U.S.
    

Foreign securities involve currency risks. The U.S.
dollar value of a foreign security tends to decrease
when the value of the dollar rises against the foreign
currency in which the security is denominated and tends
to increase when the value of the dollar falls against
such currency. Fluctuations in exchange rates may also
affect the earning power and asset value of the foreign
entity issuing the security. Dividend and interest
payments may be returned to the country of origin, based
on the exchange rate at the time of disbursement, and
restrictions on capital flows may be imposed. Losses and
other expenses may be incurred in converting between
various currencies in connections with purchases and
sales of foreign securities.

Foreign stock markets are generally not as developed or
efficient as those in the U.S. In most foreign markets
volume and liquidity are less than in the U.S. and, at
times, volatility of price can be greater than that in
the U.S. Fixed commissions on foreign stock exchanges
are generally higher than the negotiated commissions on
U.S. exchanges. There is generally less government
supervision and regulation of foreign stock exchanges,
brokers and companies than in the U.S.

There is also the possibility of adverse changes in
investment or exchange control regulations,
expropriation or confiscatory taxation, limitations on
the removal of funds or other assets, political or
social instability, or diplomatic developments which
could adversely affect investments, assets or securities
transactions of the Fund in some foreign countries. The
Fund is not aware of any investment or exchange control
regulations which might substantially impair the
operations of the Fund as described, although this could
change at any time.

Investing in emerging markets in particular, those
countries whose economies and capital markets are not as
developed as those of more industrialized nations,
carries its own special risks. Among other risks, the
economies of such countries may be affected to a greater
extent than in other countries by price fluctuations of
a single commodity, by severe cyclical climactic
conditions, lack of significant history in operating
under a market-oriented economy, or by political
instability, including risk of expropriation.

For many foreign securities, there are U.S.
dollar-denominated American Depositary Receipts
("ADRs"), which are traded in the U.S. on exchanges or
over the counter and are generally sponsored and issued
by domestic banks. ADRs represent the right to receive
securities of foreign issuers deposited in a domestic
bank or a correspondent bank. ADRs do not eliminate all
the risk inherent in investing in the securities of
foreign issuers. However, by investing in ADRs rather
than directly in foreign issuers' stock, the Portfolio
may avoid currency risks during the settlement period
for either purchases or sales. In general, there is a
large, liquid market in the U.S. for many ADRs. The
information available for ADRs is subject to the
accounting, auditing and financial reporting standards
of the domestic market or exchange on which they are
traded, which standards are more uniform and more
exacting than those to which many foreign issuers may be
subject. The Portfolio may also invest in European
Depositary Receipts ("EDRs"), which are receipts
evidencing an arrangement with a European bank similar
to that for ADRs and are designed for use in the
European securities markets. EDRs are not necessarily
denominated in the currency of the underlying security.

The dividends and interest payable on certain of the
Portfolio's foreign securities may be subject to foreign
withholding taxes, thus reducing the net amount
available for distribution to shareholders. You should
understand that the expense ratio of the Portfolio can
be expected to be higher than those of investment
companies investing only in domestic securities since
the costs of operations are higher.

 ..........................................................

   
Writing (Selling) Call and Put Options.
    

A call option on a security, security index or a foreign
currency gives the purchaser of the option, in return
for the premium paid to the writer (seller), the right
to buy the underlying security, index or foreign
currency at the exercise price at any time during the
option period. Upon exercise by the purchaser, the
writer of a call option on an individual security or
foreign currency has the obligation to sell the
underlying security or currency at the exercise price. A
call option on a securities index is similar to a call
option on an individual security, except that the value
of the option depends on the weighted value of the group
of securities comprising the index and all settlements
are made in cash. A call option may be terminated by the
writer (seller) by entering into a closing purchase
transaction in which it purchases an option of the same
series as the option previously written.

A put option on a security, security index, or foreign
currency gives the purchaser of the option, in return
for the premium paid to the writer (seller), the right
to sell the underlying security, index, or foreign
currency at the exercise price at any time during the
option period.

Upon exercise by the purchaser, the writer of a put
option has the obligation to purchase the underlying
security or foreign currency at the exercise price. A
put option on a securities index is similar to a put
option on an individual security, except that the value
of the option depends on the weighted value of the group
of securities comprising the index and all settlements
are made in cash.

The Portfolio may write exchange-traded call options on
its securities. Call options may be written on portfolio
securities, securities indices, or foreign currencies.
With respect to securities and foreign currencies, the
Portfolio may write call and put options on an exchange
or over-the-counter. Call options on portfolio
securities will be covered since the Portfolio will own
the underlying securities or other securities that are
acceptable for escrow at all times during the option
period. Call options on securities indices will be
written only to hedge in an economically appropriate way
portfolio securities which are not otherwise hedged with
options or financial futures contracts and will be
"covered" by identifying the specific portfolio
securities being hedged. Call options on foreign
currencies and put options on securities and foreign
currencies will be covered by securities acceptable for
escrow. The Portfolio may not write options on more than
50% of its total assets. Management presently intends to
cease writing options if and as long as 25% of such
total assets are subject to outstanding options
contracts or if required under regulations of state
securities administrators.

The Portfolio will write call and put options in order
to obtain a return on its investments from the premiums
received and will retain the premiums whether or not the
options are exercised. Any decline in the market value
of portfolio securities or foreign currencies will be
offset to the extent of the premiums received (net of
transaction costs). If an option is exercised, the
premium received on the option will effectively increase
the exercise price or reduce the difference between the
exercise price and market value.

During the option period, the writer of a call option
gives up the opportunity for appreciation in the market
value of the underlying security or currency above the
exercise price. It retains the risk of loss should the
price of the underlying security or foreign currency
decline. Writing call options also involves risks
relating to the Portfolio's ability to close out options
it has written.

During the option period, the writer of a put option has
assumed the risk that the price of the underlying
security or foreign currency will decline below the
exercise price. However, the writer of the put option
has retained the opportunity for appreciation above the
exercise price should the market price of the underlying
security or foreign currency increase. Writing put
options also involves risks relating to the Portfolio's
ability to close out options it has written.

 ..........................................................

Purchasing Call and Put Options.

The Portfolio may invest up to an aggregate of 5% of its
total assets in exchange-traded or over-the-counter call
and put options on securities and securities indices and
foreign currencies. Purchases of such options may be
made for the purpose of hedging against changes in the
market value of the underlying securities or foreign
currencies. The Portfolio may invest in call and put
options whenever, in the opinion of the Advisor or
Subadvisor, a hedging transaction is consistent with its
investment objectives. The Portfolio may sell a call
option or a put option which it has previously purchased
prior to the purchase (in the case of a call) or the
sale (in the case of a put) of the underlying security
or foreign currency. Any such sale would result in a net
gain or loss depending on whether the amount received on
the sale is more or less than the premium and other
transaction costs paid on the call or put which is sold.
Purchasing a call or put option involves the risk that
the Portfolio may lose the premium it paid plus
transaction costs.

 ..........................................................

Financial Futures and Related Options.

The Portfolio may enter into financial futures contracts
and related options as a hedge against anticipated
changes in the market value of its securities or
securities which it intends to purchase or in the
exchange rate of foreign currencies. Hedging is the
initiation of an offsetting position in the futures
market which is intended to minimize the risk associated
with a position's underlying securities in the cash
market. Investment techniques related to financial
futures and options are summarized below and are
described more fully in the Statement of Additional
Information.

Financial futures contracts consist of interest rate
futures contracts, foreign currency futures contracts
and securities index futures contracts. An interest rate
futures contract obligates the seller of the contract to
deliver, and the purchaser to take delivery of, the
interest rate securities called for in the contract at a
specified future time and at a specified price. A
foreign currency futures contract obligates the seller
of the contract to deliver, and the purchaser to take
delivery of, the foreign currency called for in the
contract at a specified future time and at a specified
price. A securities index assigns relative values to the
securities included in the index, and the index
fluctuates with changes in the market values of the
securities so included. A securities index futures
contract is a bilateral agreement pursuant to which two
parties agree to take or make delivery of an amount of
cash equal to a specified dollar amount times the
difference between the index value at the close of the
last trading day of the contract and the price at which
the futures contract is originally struck. An option on
a financial futures contract gives the purchaser the
right to assume a position in the contract (a long
position if the option is a call and a short position if
the option is a put) at a specified exercise price at
any time during the period of the option.

The Portfolio may purchase and sell financial futures
contracts which are traded on a recognized exchange or
board of trade and may purchase exchange or board-traded
put and call options on financial futures contracts. It
will engage in transactions in financial futures
contracts and related options only for hedging purposes
and not for speculation. In addition, the Portfolio will
not purchase or sell any financial futures contract or
related option if, immediately thereafter, the sum of
the cash or U.S. Treasury bills committed with respect
to its existing futures and related options positions
and the premiums paid for related options would exceed
5% of the market value of its total assets. At the time
of purchase of a futures contract or a call option on a
futures contract, an amount of cash, U.S. Government
securities or other appropriate high-grade debt
obligations equal to the market value of the futures
contract minus the Portfolio's initial margin deposit
with respect thereto, will be deposited in a segregated
account with the Fund's custodian bank to collateralize
fully the position and thereby ensure that it is not
leveraged. The extent to which the Portfolio may enter
into financial futures contracts and related options may
also be limited by requirements of the Internal Revenue
Code of 1986 for qualification as a regulated investment
company.

Engaging in transactions in financial futures contracts
involves certain risks, such as the possibility of an
imperfect correlation between futures market prices and
cash market prices and the possibility that the Advisor
or Subadvisor could be incorrect in its expectations as
to the direction or extent of various interest rate
movements or foreign currency exchange rates, in which
case the Portfolio's return might have been greater had
hedging not taken place. There is also the risk that a
liquid secondary market may not exist. The risk in
purchasing an option on a financial futures contract is
that the Portfolio will lose the premium it paid. Also,
there may be circumstances when the purchase of an
option on a financial futures contract would result in a
loss to the Portfolio while the purchase or sale of the
contract would not have resulted in a loss.

 ..........................................................

FOREIGN CURRENCY TRANSACTIONS
The value of the Portfolio's assets as measured in
United States dollars may be affected favorably or
unfavorably by changes in foreign currency exchange
rates and exchange control regulations, and the
Portfolio may incur costs in connection with conversions
between various currencies. The Portfolio will conduct
its foreign currency exchange transactions either on a
spot (i.e., cash) basis at the spot rate prevailing in
the foreign currency exchange market, or through forward
contracts to purchase or sell foreign currencies. A
forward foreign currency exchange contract involves an
obligation to purchase or sell a specific currency at a
future date, which may be any fixed number of days from
the date of the contract agreed upon by the parties, at
a price set at the time of the contract. These contracts
are traded directly between currency traders (usually
large commercial banks) and their customers.

When the Portfolio enters into a contract for the
purchase or sale of a security denominated in a foreign
currency, it may want to establish the United States
dollar cost or proceeds, as the case may be. By entering
into a forward contract in United States dollars for the
purchase or sale of the amount of foreign currency
involved in the underlying security transaction, the
Portfolio is able to protect itself against a possible
loss between trade and settlement dates resulting from
an adverse change in the relationship between the United
States dollar and such foreign currency. However, this
tends to limit potential gains which might result from a
positive change in such currency relationships. The
Portfolio may also hedge its foreign currency exchange
rate risk by engaging in currency financial futures and
options transactions.

When the Advisor or the Subadvisor believes that the
currency of a particular foreign country may suffer a
substantial decline against the United States dollar, it
may enter into a forward contract to sell an amount of
foreign currency approximating the value of some or all
of the Portfolio's portfolio securities denominated in
such foreign currency. The forecasting of short-term
currency market movement is extremely difficult and
whether such a short-term hedging strategy will be
successful is highly uncertain.

It is impossible to forecast with precision the market
values of portfolio securities at the expiration of a
contract. Accordingly, it may be necessary for the
Portfolio to purchase additional currency on the spot
market (and bear the expense of such purchase) if the
market value of the security is less than the amount of
foreign currency the Portfolio is obligated to deliver
when a decision is made to sell the security and make
delivery of the foreign currency in settlement of a
forward contract. Conversely, it may be necessary to
sell on the spot market some of the foreign currency
received upon the sale of the portfolio security if its
market value exceeds the amount of foreign currency the
Portfolio is obligated to deliver.

If the Portfolio retains the portfolio security and
engages in an offsetting transaction, it will incur a
gain or a loss (as described below) to the extent that
there has been movement in forward contract prices. If
the Portfolio engages in an offsetting transaction, it
may subsequently enter into a new forward contract to
sell the foreign currency. Should forward prices decline
during the period between the Portfolio's entering into
a forward contract for the sale of a foreign currency
and the date it enters into an offsetting contract for
the purchase of the foreign currency, it would realize
gains to the extent the price of the currency it has
agreed to sell exceeds the price of the currency it has
agreed to purchase. Should forward prices increase, the
Portfolio would suffer a loss to the extent the price of
the currency it has agreed to purchase exceeds the price
of the currency it has agreed to sell. Although such
contracts tend to minimize the risk of loss due to a
decline in the value of the hedged currency, they also
tend to limit any potential gain which might result
should the value of such currency increase. The
Portfolio may have to convert its holdings of foreign
currencies into United States dollars from time to time.
Although foreign exchange dealers do not charge a fee
for conversion, they do realize a profit based on the
difference (the "spread") between the prices at which
they are buying and selling various currencies.

 ..........................................................

   
ADDITIONAL NONFUNDAMENTAL INVESTMENT POLICIES
Calvert Social International Equity has adopted the
following operating (i.e., nonfundamental) investment
policies which may be changed by the Board of Directors
without shareholder approval:
    

The Portfolio may not purchase illiquid securities if
more than 15% of the value of its net assets would be
invested in such securities. Further, the Portfolio may
not acquire private placement investments until the
value of its assets exceeds $20 million.

For further information on the Portfolio's investment
policies and restrictions, as well as a description of
the types of securities that may be purchased, see the
Statement of Additional Information.


ADDITIONAL RISK FACTORS
Interest Rate Risk

All fixed income instruments are subject to
interest-rate risk: that is, if 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 will be.

 ..........................................................

Noninvestment-grade Securities

Noninvestment-grade securities tend to be less sensitive
to interest rate changes than higher-rated investments,
but are more sensitive to adverse economic changes and
individual corporate developments. This may affect the
issuer's ability to make principal and interest payments
on the debt obligation. There is also a greater risk 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, it may be difficult for the
Portfolio to sell the securities. Because of a lack of
objective data, a thinly-traded market may make it
difficult to value the securities, so that the Board of
Directors may have to exercise its judgment in assigning
a value. See the Appendix in the Statement of Additional
Information for more information on bond ratings.

 ..........................................................

                    INVESTMENT SCREENS
- ----------------------------------------------------------

The Portfolio carefully reviews a company's policies and
behavior in the following social issues: environment,
nuclear energy, weapons systems, health care, human
rights, and alcohol/tobacco. The Portfolio currently
observes the following operating policies which may be
changed by the Portfolio's Board of Directors without
shareholder approval:

1.   The Portfolio actively seeks to invest in companies
     that achieve excellence in both financial return
     and environmental soundness, selecting issuers that
     take positive steps toward preserving our
     environment and avoiding companies with poor
     environmental records.

2.   The Portfolio will not invest in issuers primarily
     engaged in the manufacture of weapons systems, the
     production of nuclear energy, or the manufacture of
     equipment to produce nuclear energy.

3.   The Portfolio actively seeks to invest in companies
     whose products or services improve the quality of
     or access to health care, including public health
     and preventative medicine.

The Portfolio believes that there are long-term benefits
inherent in an investment philosophy that demonstrates
concern for the environment, human rights, economic
priorities, and international relations. Those
enterprises which exhibit a social awareness measured in
terms of the above attributes and considerations should
be better prepared to meet future societal needs for
goods and services. By responding to social concerns,
these enterprises should not only avoid the liability
that may be incurred when a product or services is
determined to have a negative social impact or has
outlived its usefulness, but also be better positioned
to develop opportunities to make a profitable
contribution to society. These enterprises should be
ready to respond to external demands and ensure that
over the longer term they will be viable to provide a
positive return to both investors and society as a whole.

               THE FUND AND ITS MANAGEMENT
- ----------------------------------------------------------

   
Calvert Variable Series, Inc. (the "Fund"), a Maryland
corporation, is an open-end investment company, which
was incorporated under the laws of the State of Maryland
on September 27, 1982. The Board of Directors supervises
the business affairs and investments of the Fund, which
are managed on a daily basis by the Fund's Investment
Advisor. The Fund has several investment Portfolios,
each issuing one class of stock. The shares of the Fund
currently are sold only to insurance companies
(collectively, the "Insurance Companies") for allocation
to their separate accounts (collectively, the "Variable
Accounts") to fund the benefits under certain variable
annuity and variable life insurance policies
(collectively, the "Policies") issued by such companies.
Accordingly, the interest of a policy owner in the
shares is subject to the terms of the particular annuity
or life insurance policy and is described in the
attached prospectus for one of the Policies, which
should be reviewed carefully by a person considering the
purchase of a Policy. The rights of the Insurance
Companies as shareholders should be distinguished from
the rights of a policy owner which are described in the
Policies. Policy owners should consider that the
investment return experience of the Portfolio will
affect the value of the policy and the amount of annuity
payments or life insurance benefits received under a
policy. See the attached prospectus(es) for the Policies
for a description of the relationship between increases

Investment Advisor and Subadvisor

   
Calvert Asset Management Company, Inc. (the "Advisor"),
4550 Montgomery Avenue, Suite 1000N, Bethesda, Maryland
20814, is the Investment Advisor to all of the Fund's
Portfolios. It is a wholly-owned subsidiary of Calvert
Group, Ltd., which is in turn an indirect wholly-owned
subsidiary of Acacia Mutual Life Insurance Company. As
of December 31, 1997, Calvert Group, Ltd. had assets
under management and administration in excess of $5.0
billion. Pursuant to its investment advisory agreement
with the Fund, the Investment Advisor manages the
investment and reinvestment of the assets of each
Portfolio and is responsible for the overall management
of the business affairs of each Portfolio, subject to
the direction and authority of the Fund's Board of
Directors. The Advisor has retained an investment
subadvisor ("Subadvisor") for Calvert Social
International Equity. The Advisor will continuously
monitor and evaluate the performance and investment
style of the Subadvisor.

The Subadvisor to Calvert Social International Equity is
Murray Johnstone International, Ltd. of Glasgow,
Scotland, which has its principal U.S. office in
Chicago, Illinois, and is a wholly-owned subsidiary of
United Asset Management Company. Murray Johnstone
manages the investment and reinvestment of the assets of
Calvert Social International Equity, although the
Advisor may manage part of Calvert Social International
Equity's cash reserves required for liquidity purposes.
Andrew Preston, Calvert Social International Equity
Portfolio Manager, studied at Melbourne University in
Australia and Ritsumeikan University in Japan prior to
working for the Australian Department of Foreign
Affairs. He joined Murray Johnstone in 1985 as an
analyst in the U.K. and U.S. departments, became Fund
Manager in the Japanese Department, and played a
prominent role in the establishment and operation of
Yamaichi-Murray Johnstone.
    

Advisory Fee

   
For its services, the Advisor receives a fee based on a
percentage of the average daily net assets of the
Portfolio. For 1997, the Advisor received a fee of 1.00%
of net assets of Calvert Social International Equity,
and from this paid a fee of 0.45% of the net assets of
Calvert Social International Equity to Murray Johnstone
International, Ltd. as a subadvisory fee.

Calvert Administrative Services Company ("CASC"), an
affiliate of the Advisor, has been retained by Calvert
Social International Equity to provide certain
administrative services necessary to the conduct of
their affairs, including the preparation of regulatory
filings and shareholder reports, the daily determination
of net asset value per share and dividends, and the
maintenance of portfolio and general accounting records.
For providing such services, CASC is entitled to receive
a fee from the Portfolio of 0.10% of net assets per year
with a minimum fee of $40,000 for Calvert Social
International Equity. During 1997, CASC received a fee
of 0.10%.
    

 ..........................................................

Expenses

   
The Portfolio's expenses, which are accrued daily,
include: the fee of the Investment Advisor; costs of
executing portfolio transactions; pricing costs;
interest; taxes; custodian and transfer agent fees;
legal and auditing fees; bookkeeping and dividend
disbursing expenses; and certain other expenses relating
to the Fund's operations. Certain expenses are paid by
the particular Portfolio that incurs them, while other
expenses are allocated among each Portfolio on the basis
of their relative size (based on net assets), or as
designated by the Board of Directors, as appropriate.
Expenses constituted 1.56% of the average net assets of
the Portfolio for 1997, including fees paid indirectly,
and 1.17% net of fees paid indirectly and reimbursements.
    

 ..........................................................

Capital Stock

   
The Fund issues separate stock for each of its
Portfolios. Shares of each of the Portfolios have equal
rights with regard to voting, redemptions, dividends,
distributions, and liquidations. No Portfolio has
preference over another Portfolio. When issued, shares
are fully paid and nonassessable and do not have
preemptive or conversion rights or cumulative voting
rights. The Insurance Companies and the Fund's
shareholders will vote Fund shares allocated to
registered separate accounts in accordance with
instructions received from policyholders. Aegon
Financial Services Group, Inc. (formerly, Providian Life
and Health Insurance Company) owns more than 25% of the
outstanding stock of the Portfolio. Under certain
circumstances, which are described in the accompanying
prospectus of the variable life or annuity policy, the
voting instructions received from variable life or
annuity policyholders may be disregarded.
    

 ..........................................................

            PURCHASE AND REDEMPTION OF SHARES
- ----------------------------------------------------------

The Fund offers its shares, without sales charge, only
for purchase by various Insurance Companies for
allocation to their Variable Accounts. Shares are
purchased by the Variable Accounts at the net asset
value of the Portfolio next determined after the
Insurance Company receives the premium payment. The Fund
continuously offers its shares in the Portfolio at a
price equal to the net asset value per share. Initial
and subsequent payments allocated to a Portfolio are
subject to the limits applicable in the Policies issued
by the Insurance Companies.

It is conceivable that in the future it may be
disadvantageous for both annuity Variable Accounts and
life insurance Variable Accounts, or for Variable
Accounts of different Insurance Companies, to invest
simultaneously in the Fund, although currently neither
the Insurance Companies nor the Fund foresee any such
disadvantages to either variable annuity or variable
life insurance policyholders of any Insurance Company.
The Fund's Board of Directors intends to monitor events
in order to identify any material conflict between such
policyholders and to determine what action, if any,
should be taken in response to the problem.

The Insurance Companies redeem shares of the Fund to
make benefit and surrender payments under the terms of
their Policies. Redemptions are processed on any day on
which the Fund is open for business (each day the New
York Stock Exchange is open), and are made at the
Portfolio's net asset value next determined after the
appropriate Insurance Company receives a surrender
request in acceptable form.

Payment for redeemed shares will be made promptly, and
in no event later than seven days. However, the right of
redemption may be suspended or the date of payment
postponed in accordance with the Rules under the
Investment Company Act of 1940. The amount received on
redemption of the shares of the Portfolio may be more or
less than the amount paid for the shares, depending on
the fluctuations in the market value of the assets owned
by the Portfolio. The Fund redeems all full and
fractional shares of the Portfolio for cash.

The net asset value of the shares of the Portfolio is
determined once daily as of the close of business of the
New York Stock Exchange, on days when the Exchange is
open for business, or for any other day when there is a
sufficient degree of trading in the investments of the
Portfolio to affect materially its net asset value per
share (except on days when no orders to purchase or
redeem shares of the Portfolio have been received). The
net asset value is determined by adding the values of
all securities and other assets of the Portfolio,
subtracting liabilities and expenses, and dividing by
the number of outstanding shares of the Portfolio.

Except for money market instruments maturing in 60 days
or less, securities held by the Portfolio are valued at
market value if market quotations are readily available.
Otherwise, securities are valued at fair value as
determined in good faith by the Board of Directors,
although the actual calculations may be made by persons
acting pursuant to the direction of the Board. All money
market instruments with a remaining maturity of 60 days
or less held by any Portfolio, are valued on an
amortized cost basis.

 ..........................................................

               DIVIDENDS AND DISTRIBUTIONS
- ----------------------------------------------------------

   
It is the Portfolio's intention to distribute
substantially all of the net investment income, if any.
The net investment income consists of all payments of
dividends or interest received by the Portfolio less
estimated expenses, including the investment advisory
fee. All net realized capital gains, if any, are
declared and distributed periodically, at least
annually. All dividends and distributions are reinvested
in additional shares of the Portfolio at net asset value.
    

            TOTAL RETURN AND YIELD INFORMATION
- ----------------------------------------------------------

Total Return and Other Quotations

   
Calvert Social International Equity may advertise "total
return." Total return refers to the total change in
value of an investment in the Portfolio over a specified
period. Total return shows its overall change in value,
including changes in share price and assuming all of the
Portfolio's dividends and capital gain distributions are
reinvested. A cumulative total return reflects the
Portfolio's performance over a stated period of time. An
average annual total return reflects the hypothetical
annual compounded return that would have produced the
same cumulative total return if the Portfolio's
performance had been constant over the entire period.
Because average annual returns tend to smooth out
variations in the Portfolio's returns, you should
recognize that they are not the same as actual
year-by-year results. The total return of a Portfolio
generally does not include the effect of paying the
charges and expenses on the particular insurance policy
or annuity contract for which the Portfolio serves as
the investment vehicle.
    

 ..........................................................

                          TAXES
- ----------------------------------------------------------

As a "regulated investment company" under the Internal
Revenue Code of 1986, as amended, the Fund is not
subject to federal income or excise tax to the extent
that it distributes its net investment income and net
capital gains. Each Portfolio is treated as a separate
entity for federal income tax purposes. Since the sole
shareholders of the Fund are Insurance Companies, no
discussion is included here as to the federal income tax
consequences at the shareholder level. For information
concerning the federal tax consequences to purchasers of
the annuity or life insurance policies, see the
prospectuses for the Policies.

 ..........................................................

   
TRANSFER AND DIVIDEND DISBURSING AGENT
- ----------------------------------------------------------
Calvert Shareholder Services, Inc., 4550 Montgomery
Avenue, Suite 1000N, Bethesda, Maryland 20814, is the
shareholder servicing agent. National Financial Data
Services, Inc. ("NFDS"), has been retained by the Fund
to act as transfer agent and dividend disbursing agent.

INVESTMENT OBJECTIVE AND POLICIES

The investment objective of the Portfolio discussed
below is not fundamental and may be changed upon 60 days
written notice to shareholders without a shareholder
vote. There can be no assurance that the investment
objective of the Portfolio will be realized.

The investment objective of the Portfolio is to achieve
a total return above the rate of inflation through an
actively managed, nondiversified portfolio of common and
preferred stocks, bonds, and money market instruments
which offer income and capital growth opportunity and
which satisfy the social concern criteria established
for the Portfolio. The Portfolio invests in enterprises
that make a significant contribution to society through
their products and services and through the way they do
business. The Portfolio is designed for long-term
investment. It is not the policy of the Portfolio to
take great risks to obtain speculatively or aggressively
high returns. There is no predetermined percentage of
assets allocated to either stocks or bonds or money
market instruments, although, as an operating policy,
the Portfolio will have at least 25% of its assets in
fixed income senior securities. Equity investments are
selected by the Subadvisor, NCM Capital Management
Group, Inc., subject to direction and control by the
Fund's Advisor and Board of Directors. Fixed-income
investments are selected by the Advisor. The Investment
Advisors determine the mix for the Portfolio depending
upon their view of market conditions and the economic
outlook.

To implement its investment objectives, the Portfolio
uses the following strategies which, unless otherwise
specified as a fundamental policy, are operating
policies and may be changed without shareholder vote.
The Portfolio may purchase both common and preferred
stock. For its fixed-income investments, the Portfolio
normally invests in bonds which are considered
investment grade, including bonds which are direct or
indirect obligations of the U.S. Government, or which at
the date of investment are rated AAA, AA, A, or BBB by
Standard & Poor's Corporation or Aaa, Aa, A, or Baa by
Moody's Investors Service, Inc. Bonds rated Baa or BBB
are considered medium grade obligations and possess
speculative characteristics. The Portfolio may purchase
lower-rated obligations but no more than 20% of its
assets may be invested in obligations rated lower than
B. The Portfolio may purchase without limitation bonds
which are unrated but of comparable quality to bonds
rated B or better, as determined by the Advisors under
the supervision of the Board of Directors. See
Additional Risk Factors - Noninvestment-grade
Securities, and the Statement of Additional Information
for additional information concerning bond ratings.

The Portfolio may purchase money market instruments,
including repurchase agreements with recognized
securities dealers and banks secured by such
instruments, selected in accordance with the Portfolio's
social criteria. Such money market instruments may
include: obligations issued or guaranteed as to
principal by the U.S. Government, its agencies and
instrumentalities; U.S. dollar-denominated certificates
of deposit, time deposits and bankers' acceptances of
U.S. banks, generally banks with assets in excess of $1
billion; and commercial paper which at the date of
investment is rated A-1 by Standard and Poor's
Corporation or Prime-1 by Moody's Investors Service,
Inc., or if not rated, is of comparable quality.



Due to the particular social objective of the Portfolio,
opportunities may exist to promote promising approaches
to social goals through privately placed instruments.
Since private placement investments are restricted
securities and have no readily available market, the
Portfolio has a fundamental policy that such investments
in the Portfolio are limited to no more than 10% of the
Portfolio's assets.

All investments for the Portfolio are selected with a
concern for the social impact of each investment. The
Portfolio has developed the following criteria for the
selection of organizations in which the Portfolio
invests. The Portfolio seeks to invest in a producer or
service provider which:

1.   Delivers safe products and services in ways that
     sustain our natural environment.

2.   Is managed with participation throughout the
     organization in defining and achieving objectives.

3.   Negotiates fairly with its workers, provides an
     environment supportive of their wellness, does not
     discriminate on the basis of race, gender,
     religion, age, disability, ethnic origin or sexual
     orientation, does not consistently violate
     regulations of the Equal Employment Opportunity
     Commission, and provides opportunities for women,
     disadvantaged minorities and others from whom equal
     opportunities have often been denied.

4.   Fosters awareness of a commitment to human goals,
     such as creativity, productivity, self-respect, and
     responsibility, within the organization and the
     world, and continually recreates a context within
     which these goals can be realized.

The Portfolio will not invest in an issuer primarily
engaged in the production of nuclear energy or in the
manufacture of equipment to produce nuclear energy,
business activities in support of repressive regimes, or
the manufacture of weapons systems.

Each investment is selected on the basis of its
abilities to contribute to the dual objective of the
Portfolio. All potential investments are first screened
for financial soundness and then evaluated according to
the Portfolio's social criteria. To the greatest extent
possible, investments are made in companies exhibiting
unusual, positive accomplishment with respect to one or
more of the criteria. All companies must meet the
Portfolio's minimum standards for all the criteria. It
should be noted that the Portfolio's social criteria
tend to limit the availability of investment
opportunities more than is customary with other
investment companies.

The selection of an organization for investment by the
Portfolios does not constitute endorsement or validation
by the Fund, nor does the exclusion of an organization
necessarily reflect failure to satisfy the Portfolio's
social criteria. Policyholders directing investment in
the Portfolio are invited to send brief descriptions of
companies they believe might be suitable for investment
by the Portfolio.

 ..........................................................

RISKS OF FOREIGN SECURITIES
The Portfolio may invest up to 10% of its assets in the
securities of foreign issuers. There are substantial and
different risks involved in investing in foreign
securities. You should consider these risks carefully.
For example, there is generally less publicly available
information about foreign companies than is available
about companies in the U.S. Foreign companies are
generally not subject to uniform audit and financial
reporting standards, practices and requirements
comparable to those in the U.S.

Foreign securities involve currency risks. The U.S.
dollar value of a foreign security tends to decrease
when the value of the dollar rises against the foreign
currency in which the security is denominated and tends
to increase when the value of the dollar falls against
such currency. Fluctuations in exchange rates may also
affect the earning power and asset value of the foreign
entity issuing the security. Dividend and interest
payments may be returned to the country of origin, based
on the exchange rate at the time of disbursement, and
restrictions on capital flows may be imposed. Losses and
other expenses may be incurred in converting between
various currencies in connection with purchases and
sales of foreign securities.

Foreign stock markets are generally not as developed or
efficient as those in the U.S. In most foreign markets
volume and liquidity are less than in the U.S. and, at
times, volatility of price can be greater than that in
the U.S. Fixed commissions on foreign stock exchanges
are generally higher than the negotiated commissions on
U.S. exchanges. There is generally less government
supervision and regulation of foreign stock exchanges,
brokers, and companies than in the U.S.

There is also the possibility of adverse changes in
investment or exchange control regulations,
expropriation or confiscatory taxation, limitations on
the removal of funds or other assets, political or
social instability, or diplomatic developments which
could adversely affect investments, assets or securities
transactions of the Portfolio in some foreign countries.
The Portfolio is not aware of any investment or exchange
control regulations which might substantially impair the
operations of the Portfolio as described, although this
could change at any time.

Investing in emerging markets in particular, those
countries whose economies and capital markets are not as
developed as those of more industrialized nations,
carries its own special risks. Among other risks, the
economies of such countries may be affected to a greater
extent than in other countries by price fluctuations of
a single commodity, by severe cyclical climactic
conditions, lack of significant history in operating
under a market-oriented economy, or by political
instability, including risk of expropriation.

   
For many foreign securities, there are U.S.
dollar-denominated American Depositary Receipts
("ADRs"), which are traded in the U.S. on exchanges or
over the counter and are generally sponsored and issued
by domestic banks. ADRs represent the right to receive
securities of foreign issuers deposited in a domestic
bank or a correspondent bank. ADRs do not eliminate all
the risk inherent in investing in the securities of
foreign issuers. However, by investing in ADRs rather
than directly in foreign issuers' stock, the Portfolio
may avoid currency risks during the settlement period
for either purchases or sales. In general, there is a
large, liquid market in the U.S. for many ADRs. The
information available for ADRs is subject to the
accounting, auditing and financial reporting standards
of the domestic market or exchange on which they are
traded, which standards are more uniform and more
exacting than those to which many foreign issuers may be
subject. The Portfolio may also invest in European
Depositary Receipts ("EDRs"), which are receipts
evidencing an arrangement with a European bank similar
to that for ADRs and are designed for use in the
European securities markets. EDRs are not necessarily
denominated in the currency of the underlying security.
The dividends and interest payable on certain of the
Portfolio's foreign securities may be subject to foreign
withholding taxes, thus reducing the net amount
available for distribution to the Portfolio's
shareholders.
    

 ..........................................................

ADDITIONAL RISK FACTORS
Nondiversified Portfolio

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

 ..........................................................

Interest Rate Risk

All fixed income instruments are subject to
interest-rate risk: that is, if 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 will be.

 ..........................................................

   
Noninvestment-grade Securities
    

Noninvestment-grade securities tend to be less sensitive
to interest rate changes than higher-rated investments,
but are more sensitive to adverse economic changes and
individual corporate developments. This may affect the
issuer's ability to make principal and interest payments
on the debt obligation. There is also a greater risk 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, it may be difficult for the
Portfolio to sell the securities. Because of a lack of
objective data, a thinly-traded market may make it
difficult to value the securities, so that the Board of
Directors may have to exercise its judgment in assigning
a value. See the Appendix in the Statement of Additional
Information for more information on bond ratings.

 ..........................................................

REPURCHASE AGREEMENTS
A repurchase agreement is a transaction where the
Portfolio buys a security at one price and
simultaneously agrees to sell that same security back to
the original owner at a higher price. Under the
direction and supervision of the Fund's Board of
Directors, the Investment Advisor reviews the
creditworthiness of the other party to the agreement and
must find it satisfactory before engaging in a
repurchase agreement. In all instances the Portfolio
holds underlying securities with a value equal to the
total repurchase price the other party has agreed to
pay. However, in the event of the bankruptcy of the
other party, the Portfolio could experience delays in
recovering its money, may realize only a partial
recovery or even no recovery, and may also incur
disposition costs. The Portfolio is not expected
generally to invest more than a very small portion of
its assets in repurchase agreements.


   
OTHER INFORMATION
In addition to the investment policies described above,
the investment program is subject to further policies
and restrictions which are described in the Statement of
Additional Information. The Portfolio may, to a limited
extent, lend its portfolio securities and engage in
reverse repurchase agreements.

Calvert Social Balanced Portfolio's fixed-income
investment strategies caused it to have a relatively
high portfolio turnover compared to other portfolios. A
portfolio with high turnover may incur higher
transaction costs, such as custodian and settlement
fees. During fiscal 1997, brokerage commission expenses
remained relatively level even though turnover increased
significantly, since the fixed-income investments are
traded on a spread, rather than a commission basis.

Unless otherwise specified, the policies and
restrictions for the Portfolio are not fundamental and
may be changed without shareholder approval.
Policyholder inquiries should be directed to the
Portfolio at 4550 Montgomery Avenue, Suite 1000N,
Bethesda, Maryland 20814, or by calling (800) 368-2745.
    

 ..........................................................

               THE FUND AND ITS MANAGEMENT
- ----------------------------------------------------------

   
Calvert Variable Series, Inc. (the "Fund") is an
open-end investment company. The Fund was incorporated
under the laws of the State of Maryland on September 27,
1982. The Fund is a series fund which issues classes of
stock, one for each Portfolio.The shares of the Fund
currently are sold only to insurance companies
(collectively, the"Insurance Companies") for allocation
to their separate accounts (collectively, the "Variable
Accounts") to fund the benefits under certain variable
annuity and variable life insurance policies
(collectively, the "Policies") issued by such companies.
Accordingly, the interest of a policy owner in the
shares is subject to the terms of the particular annuity
or life insurance policy and is described in the
attached prospectus for one of the Policies, which
should be reviewed carefully by a person considering the
purchase of a Policy. The rights of the Insurance
Companies as shareholders should be distinguished from
the rights of a policy owner which are described in the
Policies. Policy owners should consider that the
investment return experience of the Portfolio will
affect the value of the policy and the amount of annuity
payments or life insurance benefits received under a
policy. See the attached prospectus(es) for the Policies
for a description of the relationship between increases
or decreases in the net asset value of Portfolio shares
(and any distributions on such shares) and the benefits
provided under a policy.
    

 ..........................................................

Investment Advisor

The Fund's investment advisor is Calvert Asset
Management Company, Inc. (the "Investment Advisor"),
which is located at 4550 Montgomery Avenue, Suite 1000N,
Bethesda, Maryland 20814. Calvert Asset Management is a
wholly-owned subsidiary of Calvert Group, Ltd., which is
in turn an indirect wholly-owned subsidiary of Acacia
Mutual Life Insurance Company. As of December 31, 1997,
Calvert Group, Ltd. had assets in excess of $5.0 billion
under management and administration. Pursuant to its
investment advisory agreement with the Fund, the
Investment Advisor manages the fixed-income investments
of the Portfolio and is responsible for the overall
management of the

business affairs of each Portfolio, subject to the
direction and authority of the Fund's Board of Directors.

The Subadvisor to the Portfolio is NCM Capital
Management Group, Inc. ("NCM"). Pursuant to its
Investment Subadvisory Agreement with the Investment
Advisor, NCM manages the equity portion of the
Portfolio. NCM was founded by Maceo K. Sloan in 1986 as
a subsidiary of North Carolina Mutual Life Insurance
Company, which was established by Mr. Sloan's ancestors
in 1898 and is one of the oldest and largest
minority-owned financial institutions in the country.
NCM has been an employee-owned subsidiary of Sloan
Financial Group since 1991. Sloan Financial Group is
controlled by Mr. Sloan and Justin F. Beckett, Executive
Vice President and a Director of NCM. NCM is one of the
largest minority-owned investment management firms in
the country, and provides products in equity,
fixed-income and balanced portfolio management. It is
also one of the industry leaders in the employment and
training of minority and women investment professionals.
NCM has served as subadvisor to the Portfolio since
February 1995. Sloan Holdings, also controlled by
Messrs. Sloan and Beckett, receives a 0.05% consultation
fee, paid by the Advisor (not the Fund) for
noninvestment advice, such as marketing assistance.

RenoJ. Martini, Senior Vice President and Chief
Investment Officer of the Advisor, heads the
fixed-income portion of the Portfolio. Mr. Martini
oversees the management of all Calvert portfolios and
has served as manager of the Portfolio Investment
Department since 1985. He has extensive experience
evaluating and purchasing fixed-income securities.

 ..........................................................

Advisory Fee

   
For fiscal year 1997, the Investment Advisor received
from the Portfolio a monthly base fee, computed on a
daily basis at an annual rate of 0.70% of the average
daily net assets of the Portfolio, plus a performance
fee adjustment of 0.053% as described below.

The Advisor pays the Subadvisor a base fee of 0.25% of
the Portfolio's average net assets. In addition, under
the circumstances described below, the Advisor and
Subadvisor may earn (or have their fees reduced by)
performance fee adjustments based on the extent to which
performance of the Portfolio exceeds or trails the
Lipper Balanced Funds Index. Payment of the performance
fee adjustment began July 1, 1996. The specific
adjustments are as follows:
    

Advisor's Performance Fee Adjustment

Performance versus the         Performance Fee
Lipper Balanced Funds Index    Adjustment
- ----------------------------------------------------------

6% to less than 12%            0.05%
12% to less than 18%           0.10%
18% or more                    0.15%

Subadvisor's Performance Fee Adjustment

Performance versus the        Performance Fee
Lipper Balanced Funds Index   Adjustment
- ----------------------------------------------------------

6% to less than 12%            0.05%
12% to less than 18%           0.10%
18% or more                    0.15%

The performance fee adjustment to the Subadvisor is paid
out of the fee the Advisor receives from the Portfolio.
The initial performance period is the twelve month
period from July 1, 1995, and July 1, 1996. Each month
an additional month's performance will be factored into
the calculation until a total of 36 months comprises the
performance computation period. Payment by the Portfolio
of the performance adjustment will be conditioned on:
(1) the performance of the Portfolio as a whole having
exceeded the Lipper Balanced Funds Index; and (2)
payment of the performance adjustment not causing the
Portfolio's performance to fall below the Lipper
Balanced Funds Index.

 ..........................................................

Expenses

The Advisor provides the Fund with investment
supervision and management; certain administrative
services and office space; furnishes executive and other
personnel to the Fund; and pays the salaries and fees of
all Directors who are affiliated persons of the Advisor.
The Advisor may also assume and pay certain advertising
and promotional expenses of the Funds and reserves the
right to compensate broker-dealers in return for their
promotional or administrative services. The Fund pays
all other operating expenses, including the fee of the
Investment Advisor; costs of executing portfolio
transactions; pricing costs; interest; taxes; custodian
and transfer agent fees; legal and auditing fees;
bookkeeping and dividend disbursing expenses; and
certain other expenses relating to operations. Certain
expenses are paid by the Portfolio that incurs them,
while other expenses are allocated among each of the
Fund's Portfolios on the basis of its relative size (that
is, the amount of its net assets), or by the Board of
Directors as appropriate.

   
Expenses constituted 0.80% of the average net assets of
the Portfolio for 1997, including fees paid indirectly,
and 0.77% net of fees paid indirectly.
    


Capital Stock

   
The Fund issues separate shares of stock for each of its
Portfolios. Shares of each of the Portfolios have equal
rights with regard to voting, redemptions, dividends,
distributions, and liquidations with respect to that
Portfolio. No Portfolio has preference over another
Portfolio. When issued, shares are fully paid and
nonassessable and do not have preemptive or conversion
rights or cumulative voting rights. The Fund's
shareholders, the Insurance Companies, will vote Fund
shares allocated to the Variable Accounts in accordance
with instructions received from policy owners. Under
certain circumstances, which are described in the
accompanying prospectus of the variable life policy, the
voting instructions received from variable life
insurance policy owners may be disregarded.
    

 ..........................................................

            PURCHASE AND REDEMPTION OF SHARES
- ----------------------------------------------------------

The Fund offers its shares, without sales charge, only
for purchase by the Insurance Companies for allocation
to their Variable Accounts. Shares are purchased by the
Variable Accounts at the net asset value of the
Portfolio next determined after the Insurance Company
receives the premium payment. The Fund continuously
offers its shares in the Portfolio at a price equal to
the net asset value per share. Initial and subsequent
payments allocated to the Fund are subject to the limits
applicable in the Policies issued by the Insurance
Companies.

It is conceivable that in the future it may be
disadvantageous for both annuity Variable Accounts and
life insurance Variable Accounts, or for Variable
Accounts of different Insurance Companies, to invest
simultaneously in the Fund, although currently neither
the Insurance Companies nor the Fund foresee any such
disadvantages to either variable annuity or variable
life insurance policy owners of any Insurance Company.
The Fund's Board of Directors intends to monitor events
in order to identify any material conflicts between such
policy owners and to determine what action, if any,
should be taken in response thereto.

The Insurance Companies redeem shares of the Portfolio
to make benefit and surrender payments under the terms
of Policies. Redemptions are processed on any day on
which the Fund is open for business (each day the New
York Stock Exchange is open), and are effected at the
Portfolio's net asset value next determined after the
appropriate Insurance Company receives a surrender
request in acceptable form.
Payment for redeemed shares will be made promptly, but
in no event later than seven days. However, the right of
redemption may be suspended or the date of payment
postponed in accordance with the Rules under the 1940
Act. The amount received upon redemption of the shares
of the Fund may be more or less than the amount paid for
the shares, depending upon the fluctuations in the
market value of the assets owned by the Fund. The Fund
redeems all full and fractional shares of the Portfolio
for cash. The redemption price is the net asset value
per share.

The net asset value of the shares of the Portfolio is
determined once daily as of the close of business of the
New York Stock Exchange, on days when the Exchange is
open for business, or for any other day when there is a
sufficient degree of trading in the investments of the
Portfolio to affect materially its net asset value per
share (except on days when no orders to purchase or
redeem shares of the Portfolio have been received). The
net asset value is determined by adding the values of
all securities and other assets of the Portfolio,
subtracting liabilities and expenses, and dividing by
the number of outstanding shares of the Portfolio.

Except for money market instruments maturing in 60 days
or less, securities held by the Portfolio are valued at
their market value if market quotations are readily
available. Otherwise, such securities are valued at fair
value as determined in good faith by the Board of
Directors, although the actual calculations may be made
by persons acting pursuant to the direction of the
Board. All money market instruments with a remaining
maturity of 60 days or less are valued on an amortized
cost basis.

 ..........................................................

               DIVIDENDS AND DISTRIBUTIONS
- ----------------------------------------------------------

It is the Fund's intention to distribute substantially
all of the net investment income, if any, of the
Portfolio. For dividend purposes, net investment income
of the Portfolio consists of all payments of dividends
or interest received by such Portfolio less estimated
expenses (including the investment advisory fee). All
net realized capital gains, if any, of each Portfolio
are declared and distributed periodically, no less
frequently than annually. All dividends and
distributions are reinvested in additional shares of the
Portfolio at net asset value.

                 TOTAL RETURN INFORMATION
- ----------------------------------------------------------

The Portfolio may advertise its "total return" from time
to time. Total return refers to the total change in
value of an investment in the Portfolio over a specified
period. It differs from yield in that yield figures
measure only the income component of the Portfolio's
portfolio investments, while 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. The total return of the Portfolio is the
ratio of the increase (or decrease) in value of a
hypothetical investment in the Portfolio at the end of a
measuring period to the amount initially invested in the
Portfolio. Total return is computed by taking the total
number of shares purchased by a hypothetical $1,000
investment, adding all additional shares purchased
within the period with reinvested dividends and
distributions, calculating the value of those shares at
the end of the period, and dividing the result by the
initial $1,000 investment. For periods of more than one
year, the cumulative total return is then adjusted for
the number of years, taking compounding into account, to
calculate average annual total return during that
period. Total return is historical in nature and is not
intended to indicate future performance.

Actual total return quotations may also be advertised
for other specified periods, such as calendar years and
calendar quarters. Cumulative total return for periods
of more than one year may also be quoted. These figures
will be accompanied by the standard, average annual
total return quotations. The total return of the
Portfolio does not include the effect of paying the
charges and expenses on the particular insurance policy
or annuity contract for which the Portfolio serves as
the investment vehicle.

 ..........................................................

                          TAXES
- ----------------------------------------------------------

As a "regulated investment company" under the provisions
of Subchapter M of the Internal Revenue Code, as
amended, the Fund is not subject to federal income tax,
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 realized capital gains. Since the
only shareholders of the Fund are the Insurance
Companies, no discussion is included herein as to the
federal income tax consequences at the shareholder
level. For information concerning the federal tax
consequences to purchasers of the annuity or life
insurance policies, see the prospectuses for the
Policies.

 ..........................................................

          TRANSFER AND DIVIDEND DISBURSING AGENT
- ----------------------------------------------------------

   
Calvert Shareholder Services, Inc., 4550 Montgomery
Avenue, Suite 1000N, Bethesda, Maryland 20814, is the
shareholder servicing agent. National Financial Data
Services, Inc. ("NFDS"), has been retained by the Fund
to act as transfer agent and dividend disbursing agent.

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

   
         Calvert   Variable   Series,   Inc.,   ("the
Fund") (formerly Acacia Capital  Corporation)  offers
investors  the   opportunity  to  invest  in  several
professionally  managed  securities  portfolios which
may be  more  diversified,  stable  and  liquid  than
might be  obtainable  by an investor on an individual
basis.   In  addition,   the  Fund's  Calvert  Social
Portfolios  (formerly,  Calvert Responsibly  Invested
Portfolios   ("CRI"))  offer  the   opportunity   for
growth  of   capital  or   current   income   through
investment  in  enterprises  that make a  significant
contribution  to society  through their  products and
services  and through the way they do  business.  The
Calvert Social  Portfolios  offer  investors a choice
of five separate  portfolios  selected with a concern
for the  social  impact of each  investment:  Calvert
Social  Money  Market,   Balanced,  Mid  Cap  Growth,
International    Equity    and   Small   Cap   Growth
Portfolios.  References to the  "Investment  Advisor"
refer to the  advisor  appropriate  to the  Portfolio
being discussed. (See "Investment Advisors")
    

Foreign Securities

   
         Calvert  Social   International  Equity  and
Small Cap Growth  may  invest all of their  assets in
foreign  securities,  although  Calvert  Social Small
Cap  Growth  does not  presently  intend to invest in
foreign  securities.  Calvert  Social  Money  Market,
Balanced  and Mid Cap  Growth  may each  invest up to
25%,  and Calvert  Social  Balanced  may invest up to
10%  of  its  assets  in the  securities  of  foreign
issuers.  Calvert  Social  Money  Market may purchase
only   high    quality,    U.S.    dollar-denominated
instruments.  Investments  in foreign  securities may
present  risks not  typically  involved  in  domestic
investments.  Foreign  securities  may be affected by
such  circumstances  as possible  adverse  changes in
exchange    control   or   investment    regulations,
expropriation  or  confiscatory  taxation,  political
or  economic  instability,  and  diplomatic  or other
developments.  In purchasing foreign securities,  the
Portfolios   may   purchase    American    Depositary
Receipts    for   such    securities.    These    are
certificates    issued   by   United   States   banks
evidencing  the right to  receive  securities  of the
foreign   issuer   deposited  in  that  bank  or  its
correspondent bank.
    

         It is  contemplated  that the Portfolios may
trade foreign  securities on U.S.  securities markets
and  stock  exchanges  located  in the  countries  in
which  the  respective   principal   offices  of  the
issuers of the various  securities  are  located,  if
that   is  the   best   available   market.   Foreign
securities   markets  may  not  be  as  developed  or
efficient  as  those  in  the  United  States.  While
growing in volume,  they usually  have  substantially
less  volume  than  U.S.  securities   markets,   and
securities   of  some  foreign   companies  are  less
liquid  and  more   volatile   than   securities   of
comparable   United  States   companies.   Similarly,
volume and  liquidity  in most  foreign  bond markets
is less  than in the  United  States  and,  at times,
volatility  of  price  can  be  greater  than  in the
United States.

         Additional  costs may be incurred  which are
related  to  any  international   investment,   since
foreign  brokerage   commissions  and  the  custodial
costs associated with maintaining  foreign  portfolio
securities  are  generally  higher than in the United
States.   Fee   expense   may  also  be  incurred  on
currency   exchanges  when  the   Portfolios   change
investments  from one  country  to another or convert
foreign   securities   holdings  into  U.S.  dollars.
Foreign  companies and foreign  investment  practices
are not  generally  subject  to  uniform  accounting,
auditing  and  financial   reporting   standards  and
practices or  regulatory  requirements  comparable to
those  applicable to United States  companies.  There
may  be  less  public  information   available  about
foreign companies.

         United  States  Government  policies have at
times,  in the past,  through  imposition of interest
equalization    taxes   and    other    restrictions,
discouraged  certain  investments  abroad  by  United
States  investors.  While such taxes or  restrictions
are   not   presently   in   effect,   they   may  be
reinstituted   from  time  to  time  as  a  means  of
fostering  a  favorable   United  States  balance  of
payments.  In addition,  foreign countries may impose
withholding and taxes on dividends and interest.

         Since  investments  in securities of issuers
domiciled  in  foreign   countries   usually  involve
currencies  of the foreign  countries,  and since the
Portfolios  may  temporarily  hold  funds in  foreign
currencies   during  the   completion  of  investment
programs,  the value of the assets of the  Portfolios
as   measured  in  United   States   dollars  may  be
affected  favorably  or  unfavorably  by  changes  in
foreign   currency   exchange   rates  and   exchange
control  regulations.  For  example,  if the value of
the   foreign   currency   in  which  a  security  is
denominated  declines  in  relation  to the  value of
the U.S.  dollar,  the value of the  security in U.S.
dollars  will  decline.  Similarly,  if the  value of
the   foreign   currency   in  which  a  security  is
denominated  appreciates  in relation to the value of
the U.S.  dollar,  the value of the  security in U.S.
dollars  will   appreciate.   The   Portfolios   will
conduct  foreign   currency   exchange   transactions
either  on a spot  (i.e.,  cash)  basis  at the  spot
rate prevailing in the foreign  exchange  market,  or
through  entering into forward  contracts to purchase
or  sell  foreign   currencies.   A  forward  foreign
currency   contract   involves   an   obligation   to
purchase  or sell a  specific  currency  at a  future
date  which may be any fixed  number of days from the
date of the contract  agreed upon by the parties,  at
a  price  set at the  time  of  the  contract.  These
contracts   are  traded  in  the   interbank   market
conducted    directly    between   currency   traders
(usually   large,   commercial   banks)   and   their
customers.   A  forward  foreign  currency   contract
generally   has  no  deposit   requirement,   and  no
commissions are charged at any stage for trades.

         A Portfolio  may enter into forward  foreign
currency  contracts  for  two  reasons.   First,  the
Portfolio  may desire to preserve  the United  States
dollar  price of a  security  when it  enters  into a
contract  for the  purchase  or  sale  of a  security
denominated  in a  foreign  currency.  The  Portfolio
will be  able  to  protect  itself  against  possible
losses  resulting  from  changes in the  relationship
between   the  United   States   dollar  and  foreign
currencies  during  the period  between  the date the
security is  purchased  or sold and the date on which
payment  is  made  or  received  by  entering  into a
forward  contract  for the  purchase  or sale,  for a
fixed  amount  of  dollars,  of  the  amount  of  the
foreign   currency   involved   in   the   underlying
security transactions.

         Second,   when  the  Advisor  or  Subadvisor
believes  that the currency of a  particular  foreign
country  may  suffer a  substantial  decline  against
the United States dollar,  the Portfolio  enters into
a forward  foreign  currency  contract to sell, for a
fixed  amount  of  dollars,  the  amount  of  foreign
currency  approximating  the  value of some or all of
the  Portfolio's  investment  securities  denominated
in such  foreign  currency.  The precise  matching of
the forward  foreign  currency  contract  amounts and
the value of the portfolio  securities  involved will
not  generally be possible  since the future value of
the  securities  will  change  as  a  consequence  of
market   movements   between  the  date  the  forward
contract  is  entered  into and the date it  matures.
The   projection   of  short-term   currency   market
movement is difficult,  and the successful  execution
of this  short-term  hedging  strategy is  uncertain.
Although forward foreign  currency  contracts tend to
minimize  the  risk of loss due to a  decline  in the
value of the hedged  currency,  at the same time they
tend to limit any  potential  gain which might result
should  the  value  of such  currency  increase.  The
Portfolios  do not intend to enter into such  forward
contracts  under  this  circumstance  on a regular or
continuous basis.

Foreign Money Market Instruments

   
         Calvert   Social  Money  Market  may  invest
without  limitation  in money market  instruments  of
banks,   whether   foreign  or  domestic,   including
obligations   of  U.S.   branches  of  foreign  banks
("Yankee"  instruments)  and  obligations  of foreign
branches of U.S.  banks  ("Eurodollar"  instruments).
All  such  instruments  must  be  high-quality,  U.S.
dollar-denominated  obligations.  It is an  operating
(i.e.,   nonfundamental)  policy  of  Calvert  Social
Money  Market  that it may  invest  only  in  foreign
money market  instruments  if they are of  comparable
quality  to  the   obligations  of  domestic   banks.
Although  these   instruments   are  not  subject  to
foreign   currency   risk   since   they   are   U.S.
dollar-denominated,   investments  in  foreign  money
market   instruments   may  involve  risks  that  are
different  than  investments  in  securities  of U.S.
issuers. See "Foreign Securities" above.
    

Private Placements and Illiquid Securities

         Due to the  particular  social  objective of
the  Portfolios,  opportunities  may exist to promote
especially   promising  approaches  to  social  goals
through  privately-placed  investments.  The  private
placement  investments  undertaken by the Portfolios,
if any,  may be  subject  to a high  degree  of risk.
Such  investments  may involve  relatively  small and
untried  enterprises  that have been  selected in the
first  instance  because  of some  attractive  social
objectives  or  policies.   The  Investment  Advisors
seek to  structure  the  Portfolios'  investments  to
provide  the  greatest  assurance  of  attaining  the
intended   investment  return.  It  is  an  operating
policy of the Portfolios  that no private  placements
shall   be   acquired   until   the   value  of  that
Portfolio's investments exceeds $20 million.

         Many private  placement  investments have no
readily   available   market  and  may  therefore  be
considered  illiquid.  It is an  operating  policy of
the  Portfolios not to purchase  illiquid  securities
if more  than a  certain  percentage  of the value of
its   net   assets   would   be   invested   in  such
securities.  Securities  eligible for resale pursuant
to Rule  144A  under the  Securities  Act of 1933 may
be  determined  by  the  Board  of  Directors  to  be
liquid.  The Board may delegate  such  determinations
of liquidity to the Advisor,  pursuant to  guidelines
and  oversight  by the Board.  Portfolio  investments
in  private   placements  and  other  securities  for
which  market  quotations  are not readily  available
are  valued at fair  market  value as  determined  by
the Advisor  under the  direction  and control of the
Board.

Repurchase Agreements

         The    Portfolios    may    purchase    debt
securities  subject to repurchase  agreements,  which
are  arrangements  under which the  Portfolio  buys a
security  and the  seller  simultaneously  agrees  to
repurchase  the  security  at a  specified  time  and
price.   The   Portfolios    engage   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.  In the event of the  bankruptcy  of a
seller during the term of a repurchase  agreement,  a
legal  question  exists as to whether  the  Portfolio
would  be  deemed   the   owner  of  the   underlying
security  or would be deemed  only to have a security
interest  in  and  lien  upon  such   security.   The
Portfolios    will   only   engage   in    repurchase
agreements  with  recognized  securities  dealers and
banks  determined to present  minimal  credit risk by
the Advisor under the direction  and  supervision  of
the Board of Directors.  In addition,  the Portfolios
will   only   engage   in    repurchase    agreements
reasonably  designed to secure  fully during the term
of  the   agreement   the  seller's   obligation   to
repurchase the  underlying  security and will monitor
the market value of the  underlying  security  during
the  term  of  the  agreement.  If the  value  of the
underlying  security  declines  and is  not at  least
equal  to the  repurchase  price  due  the  Portfolio
pursuant  to  the   agreement,   the  Portfolio  will
require  the seller to pledge  additional  securities
or cash to secure the seller's  obligations  pursuant
to the  agreement.  If  the  seller  defaults  on its
obligation  to  repurchase   and  the  value  of  the
underlying  security  declines,   the  Portfolio  may
incur a loss and may incur  expenses  in selling  the
underlying   security.   Repurchase   agreements  are
always   for   periods   of  less   than  one   year.
Repurchase  agreements  not  terminable  within seven
days are considered illiquid.

Reverse Repurchase Agreements

         The  Portfolios  may also  engage in reverse
repurchase  agreements.  Under a  reverse  repurchase
agreement,  a Portfolio  sells  securities  to a bank
or securities  dealer and agrees to repurchase  those
securities  from such  party at an  agreed  upon date
and price  reflecting a market rate of interest.  The
Portfolio  invests  the  proceeds  from each  reverse
repurchase  agreement in  obligations  in which it is
authorized  to  invest.   The  Portfolios  intend  to
enter into a reverse  repurchase  agreement only when
the interest  income  provided for in the  obligation
in  which  the  Portfolio  invests  the  proceeds  is
expected  to exceed  the amount  the  Portfolio  will
pay in interest  to the other party to the  agreement
plus all  costs  associated  with  the  transactions.
The  Portfolios  do not intend to borrow for leverage
purposes.  The  Portfolios  will only be permitted to
pledge  assets  to the  extent  necessary  to  secure
borrowings and reverse repurchase agreements.

         During   the  time  a   reverse   repurchase
agreement  is   outstanding,   the   Portfolio   will
maintain  in  a  segregated   custodial   account  an
amount of cash, U.S.  Government  securities or other
liquid,  high-quality  debt securities equal in value
to the repurchase  price.  The Portfolio will mark to
market  the  value of assets  held in the  segregated
account,  and will  place  additional  assets  in the
account  whenever  the  total  value  of the  account
falls  below the  amount  required  under  applicable
regulations.

         The  Portfolios'  use of reverse  repurchase
agreements  involves  the risk that the  other  party
to   the   agreements   could   become   subject   to
bankruptcy  or  liquidation  proceedings  during  the
period  the  agreements  are  outstanding.   In  such
event,  the  Portfolio  may not be able to repurchase
the  securities  it has  sold  to that  other  party.
Under those  circumstances,  if at the  expiration of
the agreement  such  securities  are of greater value
than the  proceeds  obtained by the  Portfolio  under
the  agreements,  the  Portfolio may have been better
off had it not entered into the  agreement.  However,
the  Portfolio  will  enter into  reverse  repurchase
agreements  only  with  banks and  dealers  which the
Advisor  believes  present minimal credit risks under
guidelines   adopted   by   the   Fund's   Board   of
Directors.  In  addition,  the  Portfolio  bears  the
risk that the  market  value of the  securities  sold
by the Portfolio  may decline  below the  agreed-upon
repurchase  price,  in  which  case  the  dealer  may
request the Portfolio to post additional collateral.

   
GNMA Certificates- Calvert Social Balanced

         The Calvert  Social  Balanced  Portfolio  is
not  expected  generally  to invest more than a small
portion  of its  assets  in GNMA  Certificates.  GNMA
Certificates    are    mortgage-backed     securities
representing  part  ownership  of a pool of  mortgage
loans  that are issued by  lenders  such as  mortgage
bankers,   commercial  banks  and  savings  and  loan
associations  and are either  insured by the  Federal
Housing   Administration   or   guaranteed   by   the
Veterans  Housing  Administration.  A "pool" or group
of such  mortgages  is  assembled  and,  after  being
approved  by GNMA,  is offered to  investors  through
securities dealers.
    

         Once  approved by GNMA,  the timely  payment
of  interest  and   principal  on  each  mortgage  is
guaranteed  by GNMA and  backed by the full faith and
credit  of the  U.S.  Government.  GNMA  Certificates
differ  from  bonds in that  principal  is paid  back
monthly  by the  borrower  over  the term of the loan
rather  than  returned  in a lump  sum  at  maturity.
GNMA    Certificates   are   called    "pass-through"
securities   because  both   interest  and  principal
payments  (including  prepayments) are passed through
to the  holder  of  the  Certificate.  Upon  receipt,
principal  payments  will be reinvested by the Series
in additional securities.

         Because  interest and principal  payments on
the  underlying  mortgages  pass  through to holders,
the  average  life of GNMA  Certificates  varies with
the   maturities   of   the    underlying    mortgage
instruments,  which  have  maximum  maturities  of 30
years.   However,   because   unscheduled   principal
payments on the underlying  mortgages  resulting from
prepayment,   refinancing  or  foreclosure  are  also
passed  through to holders,  the average life of GNMA
Certificates is normally  substantially  shorter than
the  original  maturity  of the  underlying  mortgage
pools.

         The  occurrence of mortgage  prepayments  is
affected by factors  including  the level of interest
rates,  the degree of the  increase  or  decrease  in
interest   rates   over   time,    general   economic
conditions,  the  location  and age of the  mortgage,
and social and  demographic  conditions.  Prepayments
generally  occur when  interest  rates  have  fallen;
thus,  reinvestments  of principal  prepayments  will
usually be at lower rates.  Prepayments  also tend to
occur more  frequently  in mortgage  pools with rates
significantly   higher   than   prevailing   mortgage
rates.  The  coupon  rate  of  GNMA  Certificates  is
lower than the interest  rate paid on the  underlying
mortgages  only  by the  amount  of the  fee  paid to
GNMA and the issuer,  usually  1/2 of 1%.  Therefore,
GNMA  Certificates  trading at a  premium,  which are
usually     Certificates     with    coupon     rates
significantly  higher than the rates of  Certificates
being  issued at the time of  purchase,  are  subject
to greater risk of prepayment at par.

         The   Investment   Advisor   will   attempt,
through  careful  evaluation of available GNMA issues
and prevailing market  conditions,  to invest in GNMA
Certificates  which  provide a high income return but
are  not  subject  to  substantial  risk  of  loss of
principal.  Accordingly,  the  Advisor may forego the
opportunity  to  invest  in  certain  issues  of GNMA
Certificates  which  would  provide  a  high  current
income  yield if the  Advisor  determines  that  such
issues would be subject to a risk of  prepayment  and
loss of  principal  over the  long  term  that  would
outweigh the short-term increment in yield.

Noninvestment-grade Debt Securities

   
         Calvert   Social   Balanced  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  Portfolio's  investment
policy  provides  that it may not  invest  more  than
20% of its  assets  in  securities  rated  below B by
either  rating  service,  or  in  unrated  securities
determined   by  the  Advisor  to  be  comparable  to
securities  rated below B by either  rating  service.
Calvert  Social  International  Equity  may invest up
to  5%  of  its   assets   in  lower   quality   debt
securities,  and Calvert  Social Small Cap Growth may
invest  up to 35% of its  assets  in debt  securities
without      regard     to     investment      grade.
Noninvestment-grade   securities   have  moderate  to
poor  protection of principal  and interest  payments
and have speculative  characteristics.  (See Appendix
for a description of the ratings.)  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   rated
securities are, which may make them less marketable.
    

         The  quality  limitation  set  forth  in the
Portfolios'    investment    policy   is   determined
immediately  after  a  Portfolio's  acquisition  of a
given  security.  Accordingly,  any  later  change in
ratings  will  not  be  considered  when  determining
whether an investment  complies with the  Portfolio'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.

Options and Futures Contracts

   
         Calvert Social  International  Equity, Small
Cap  Growth  and Mid Cap  Growth  may,  in pursuit of
their  investment  objectives,  purchase put and call
options  and engage in the  writing  of covered  call
options and secured put options on  securities  which
meet the Portfolios'  social  criteria,  and employ a
variety    of    other     investment     techniques.
Specifically,  these  Portfolios  may also  engage in
the   purchase   and  sale  of  stock  index   future
contracts,   foreign  currency   futures   contracts,
interest  rate  futures  contracts,  and  options  on
such futures, as described more fully below.
    

         These   Portfolios   will   engage  in  such
transactions  only to hedge  the  existing  positions
in the  respective  Portfolios.  They will not engage
in   such    transactions   for   the   purposes   of
speculation  or leverage.  Such  investment  policies
and  techniques  may involve a greater degree of risk
than those inherent in more  conservative  investment
approaches.

         These  Portfolios  will not  engage  in such
options or futures  transactions  unless they receive
appropriate  regulatory  approvals permitting them to
engage   in   such   transactions.   Calvert   Social
International  Equity,  Small Cap  Growth and Mid Cap
Growth  may not  write  options  on more  than 50% of
their  total  assets.   These  Portfolios  may  write
"covered   options"   on   securities   in   standard
contracts  traded on national  securities  exchanges.
These  Portfolios  will write  such  options in order
to receive  the  premiums  from  options  that expire
and  to  seek  net  gains   from   closing   purchase
transactions with respect to such options.

         Put and  Call  Options  -  These  Portfolios
may  purchase  put  and  call  options,  in  standard
contracts  traded on national  securities  exchanges,
on securities  of issuers which meet the  Portfolios'
social  criteria.   These  Portfolios  will  purchase
such  options  only to hedge  against  changes in the
value of securities the  Portfolios  hold and not for
the purposes of  speculation  or leverage.  In buying
a  put,  a  Portfolio  has  the  right  to  sell  the
security at the  exercise  price,  thus  limiting its
risk of loss  through a decline in the  market  value
of the  security  until the put  expires.  The amount
of any  appreciation  in the value of the  underlying
security  will be  partially  offset by the amount of
the  premium  paid for the put option and any related
transaction  costs.  Prior to its  expiration,  a put
option  may be sold  in a  closing  sale  transaction
and any  profit or loss from the sale will  depend on
whether  the  amount  received  is more or less  than
the  premium   paid  for  the  put  option  plus  the
related transaction costs.

         These  Portfolios  may purchase call options
on  securities  that they may intend to purchase  and
that  meet  the  Portfolios'  social  criteria.  Such
transactions  may be  entered  into in order to limit
the  risk of a  substantial  increase  in the  market
price of the  security  which the  Portfolio  intends
to purchase.  Prior to its expiration,  a call option
may  be  sold  in a  closing  sale  transaction.  Any
profit  or  loss  from  such a sale  will  depend  on
whether  the  amount  received  is more or less  than
the  premium  paid  for  the  call  option  plus  the
related transaction costs.

         Covered  Options  -  These   Portfolios  may
write  only  covered   options  on  equity  and  debt
securities in standard  contracts  traded on national
securities  exchanges.  For call options,  this means
that so  long  as a  Portfolio  is  obligated  as the
writer  of a call  option,  that  Portfolio  will own
the  underlying  security  subject to the option and,
in the  case of put  options,  that  Portfolio  will,
through its  custodian,  deposit and maintain  either
cash or  securities  with a market  value equal to or
greater than the exercise price of the option.

         When  a  Portfolio  writes  a  covered  call
option,  the Portfolio  gives the purchaser the right
to purchase  the  security  at the call option  price
at any time  during  the life of the  option.  As the
writer  of  the  option,  the  Portfolio  receives  a
premium,   less  a   commission,   and  in   exchange
foregoes   the   opportunity   to  profit   from  any
increase  in  the  market   value  of  the   security
exceeding the call option price.  The premium  serves
to  mitigate  the effect of any  depreciation  in the
market value of the  security.  Writing  covered call
options  can  increase  the  income of the  Portfolio
and thus  reduce  declines in the net asset value per
share  of the  Portfolio  if  securities  covered  by
such  options  decline in value.  Exercise  of a call
option  by the  purchaser,  however,  will  cause the
Portfolio  to  forego  future   appreciation  of  the
securities covered by the option.

         When  a  Portfolio   writes  a  secured  put
option,  it will gain a profit  in the  amount of the
premium,  less a commission,  so long as the price of
the  underlying  security  remains above the exercise
price.  However,  the Portfolio  remains obligated to
purchase the  underlying  security  from the buyer of
the put  option  (usually  in the  event the price of
the security  funds below the exercise  price) at any
time  during the option  period.  If the price of the
underlying  security falls below the exercise  price,
the  Portfolio  may  realize a loss in the  amount of
the  difference  between the  exercise  price and the
sale  price  of  the   security,   less  the  premium
received.

         These  Portfolios  may  purchase  securities
that may be  covered  by call  options  solely on the
basis   of   considerations   consistent   with   the
investment    objectives    and   policies   of   the
Portfolios.   The   Portfolio   turnover   rate   may
increase  through  the  exercise  of a  call  option;
this will  generally  occur if the market  value of a
"covered"  security  increases  and the portfolio has
not entered into a closing purchase transaction.

         Risks  Related  to  Options  Transactions  -
The  Portfolios   can  close  out  their   respective
positions  in  exchange-traded  options  only  on  an
exchange  which  provides a secondary  market in such
options.   Although   these   Portfolios   intend  to
acquire and write only such  exchange-traded  options
for  which an  active  secondary  market  appears  to
exist,  there can be no assurance  that such a market
will  exist for any  particular  option  contract  at
any   particular   time.   This  might   prevent  the
Portfolios  from closing an options  position,  which
could  impair  the   Portfolios'   ability  to  hedge
effectively.  The  inability  to  close  out  a  call
position  may have an  adverse  effect  on  liquidity
because  the  Portfolio  may be  required to hold the
securities  underlying  the  option  until the option
expires or is exercised.

         Futures   Transactions  -  These  Portfolios
may  purchase and sell  futures  contracts  ("futures
contracts")  but only when,  in the  judgment  of the
Advisor,  such a  position  acts as a  hedge  against
market  changes  which  would  adversely  affect  the
securities  held  by the  Portfolios.  These  futures
contracts  may  include,  but  are  not  limited  to,
market   index   futures    contracts   and   futures
contracts based on U.S. Government obligations.

         A futures  contract is an agreement  between
two  parties to buy and sell a  security  on a future
date  which  has  the  effect  of  establishing   the
current  price  for the  security.  Although  futures
contracts  by their  terms  require  actual  delivery
and  acceptance  of  securities,  in most  cases  the
contracts are closed out before the  settlement  date
without   the  making  or  taking  of   delivery   of
securities.   Upon   buying  or   selling  a  futures
contract,   the  Portfolio  deposits  initial  margin
with its  custodian,  and  thereafter  daily payments
of  maintenance  margin  are  made  to and  from  the
executing  broker.  Payments  of  maintenance  margin
reflect   changes   in  the  value  of  the   futures
contract,  with  the  Portfolio  being  obligated  to
make such  payments if its futures  position  becomes
less  valuable and entitled to receive such  payments
if its positions become more valuable.

         These   Portfolios   may  only   invest   in
futures   contracts   to   hedge   their   respective
existing  investment  positions  and not  for  income
enhancement,   speculation   or  leverage   purposes.
Although  some  of  the  securities   underlying  the
futures   contract  may  not  necessarily   meet  the
Portfolios'   social   criteria,   any   such   hedge
position   taken   by  these   Portfolios   will  not
constitute  a  direct   ownership   interest  in  the
underlying securities.

         Futures  contracts  have  been  designed  by
boards   of  trade   which   have   been   designated
"contracts   markets"   by  the   Commodity   Futures
Trading   Commission   ("CFTC").   As   series  of  a
registered  investment  company,  the  Portfolios are
eligible  for  exclusion  from the CFTC's  definition
of  "commodity  pool  operator,"   meaning  that  the
Portfolios  may  invest in  futures  contracts  under
specified  conditions  without  registering  with the
CFTC. Among these  conditions are  requirements  that
each  Portfolio  invest in futures  only for  hedging
purposes  and that the  aggregate  initial  margin on
futures  contracts  and  premium on options  relating
to  futures  shall not  exceed 5% of the  Portfolio's
assets.   Futures   contracts   trade  on   contracts
markets  in a  manner  that is  similar  to the way a
stock  trades on a stock  exchange  and the boards of
trade,    through   their   clearing    corporations,
guarantee performance of the contracts.

         Options   on  Futures   Contracts   -  These
Portfolios   may  purchase  and  write  put  or  call
options  and sell call  options on futures  contracts
in  which a  Portfolio  could  otherwise  invest  and
which  are  traded  on a U.S.  exchange  or  board of
trade.  The  Portfolios  may also enter into  closing
transactions   with   respect  to  such   options  to
terminate  an existing  position;  that is, to sell a
put  option  already  owned and to buy a call  option
to close a position  where the  Portfolio has already
sold a corresponding call option.

         The  Portfolios  may only  invest in options
on  futures   contracts  to  hedge  their  respective
existing  investment  positions  and not  for  income
enhancement,   speculation   or  leverage   purposes.
Although  some  of  the  securities   underlying  the
futures  contract   underlying  the  option  may  not
necessarily  meet the  Portfolios'  social  criteria,
any such  hedge  position  taken by these  Portfolios
will not  constitute a direct  ownership  interest in
the underlying securities.

         An option on a  futures  contract  gives the
purchaser  the  right,  in  return  for  the  premium
paid,  to assume a position  in a futures  contract-a
long  position  if the  option  is a call and a short
position  if  the  option  is a  put-at  a  specified
exercise  price at any time  during the period of the
option.  The  Portfolios  will pay a premium for such
options  purchased or sold. In  connection  with such
options  bought  or sold,  the  Portfolios  will make
initial   margin   deposits   and  make  or   receive
maintenance  margin  payments  which reflect  changes
in  the   market   value   of  such   options.   This
arrangement  is similar  to the  margin  arrangements
applicable to futures contracts described above.

         Put  Options  on  Futures  Contracts  -  The
purchase  of put  options  on  futures  contracts  is
analogous  to the sale of  futures  contracts  and is
used to protect  the  portfolio  against  the risk of
declining  prices.  These Portfolios may purchase put
options  and sell put  options on  futures  contracts
that  are  already  owned  by  that  Portfolio.   The
Portfolios  will only  engage in the  purchase of put
options  and  the  sale of  covered  put  options  on
market index futures for hedging purposes.

         Call  Options  on  Futures  Contracts  - The
sale  of  call   options  on  futures   contracts  is
analogous  to the sale of  futures  contracts  and is
used to protect  the  portfolio  against  the risk of
declining  prices.  The  purchase of call  options on
futures  contracts  is analogous to the purchase of a
futures  contract.  These  Portfolios  may  only  buy
call  options  to close an  existing  position  where
the Portfolio has already sold a  corresponding  call
option,  or for a cash  hedge.  The  Portfolios  will
only  engage  in the  sale  of call  options  and the
purchase  of  call   options  to  cover  for  hedging
purposes.

         Writing  Call  Options on Futures  Contracts
- - The  writing of call  options on futures  contracts
constitutes  a  partial   hedge   against   declining
prices of the  securities  deliverable  upon exercise
of the  futures  contract.  If the  futures  contract
price at  expiration  is below  the  exercise  price,
the  Portfolio  will  retain  the full  amount of the
option   premium  which   provides  a  partial  hedge
against  any  decline  that may have  occurred in the
Portfolio's securities holdings.

         Risks of Options  and  Futures  Contracts  -
If  one of  these  Portfolios  has  sold  futures  or
takes  options   positions  to  hedge  its  portfolio
against  decline in the  market and the market  later
advances,  the  Portfolio  may  suffer  a loss on the
futures  contracts  or  options  which it  would  not
have  experienced  if it had not hedged.  Correlation
is also  imperfect  between  movements  in the prices
of futures  contracts  and movements in prices of the
securities  which are the subject of the hedge.  Thus
the  price of the  futures  contract  or  option  may
move  more  than  or  less  than  the  price  of  the
securities  being hedged.  Where a Portfolio has sold
futures or taken  options  positions to hedge against
decline in the  market,  the market may  advance  and
the  value of the  securities  held in the  Portfolio
may  decline.  If this were to occur,  the  Portfolio
might  lose  money  on  the  futures   contracts   or
options  and also  experience  a decline in the value
of its portfolio securities.  However,  although this
might  occur  for  a  brief  period  or  to a  slight
degree,  the value of a  diversified  portfolio  will
tend  to  move  in  the   direction   of  the  market
generally.

         The   Portfolios   can  close  out   futures
positions  only on an  exchange  or  board  of  trade
which  provides a secondary  market in such  futures.
Although  the  Portfolios  intend to purchase or sell
only  such  futures  for  which an  active  secondary
market  appears to exist,  there can be no  assurance
that  such a market  will  exist  for any  particular
futures  contract at any particular  time. This might
prevent  the   Portfolios   from  closing  a  futures
position,  which could  require a  Portfolio  to make
daily cash  payments  with respect to its position in
the event of adverse price movements.

         Options   on   futures   transactions   bear
several  risks  apart from those  inherent in options
transactions  generally.  The Portfolios'  ability to
close  out  their   options   positions   in  futures
contracts   will  depend   upon   whether  an  active
secondary  market for such  options  develops  and is
in  existence  at the  time  the  Portfolios  seek to
close  their  positions.  There  can be no  assurance
that   such  a  market   will   develop   or   exist.
Therefore,   the  Portfolios  might  be  required  to
exercise the options to realize any profit.

   
Foreign  Currency  Transactions  (Not  applicable  to
Calvert Social Money Market Portfolio)
    

         Forward    Foreign     Currency     Exchange
Contracts.   A  forward  foreign  currency   exchange
contract  involves an  obligation to purchase or sell
a specific  currency at a future  date,  which may be
any fixed  number of days  ("Term")  from the date of
the contract  agreed upon by the parties,  at a price
set at the  time  of the  contract.  These  contracts
are  traded   directly   between   currency   traders
(usually   large   commercial    banks)   and   their
customers.

         The  Portfolios  will not  enter  into  such
forward  contracts  or  maintain  a net  exposure  in
such  contracts   where  it  would  be  obligated  to
deliver  an amount of foreign  currency  in excess of
the  value  of its  portfolio  securities  and  other
assets  denominated  in that  currency.  The Advisors
and  Subadvisors  believes  that it is  important  to
have the  flexibility  to  enter  into  such  forward
contract  when  it  determines  that to do so is in a
Portfolio's best interests.

   
         Foreign  Currency  Options  (Not  applicable
to   Calvert   Social   Money   Market  or   Balanced
Portfolios). A foreign  currency  option provides the 
option buyer
with  the  right to buy or sell a  stated  amount  of
foreign  currency at the exercise  price on or before
a specified  date.  A call option gives its owner the
right,  but not the obligation,  to buy the currency,
while a put  option  gives its owner the  right,  but
not  the  obligation,   to  sell  the  currency.  The
option  seller  buyer may close its position any time
prior to  expiration  of the  option  period.  A call
rises   in   value   if   the   underlying   currency
appreciates.  Conversely,  a put  rises  in  value if
the  underlying  currency  depreciates.  Purchasing a
foreign  currency  option  can  protect  a  Portfolio
against  adverse  movement  in the value of a foreign
currency.
    

         Foreign Currency Futures  Transactions.  The
Portfolio   may   use   foreign    currency   futures
contracts  and  options  on such  futures  contracts.
Through the  purchase or sale of such  contracts,  it
may be able to  achieve  many of the same  objectives
attainable   through  the  use  of  foreign  currency
forward   contracts,   but   more   effectively   and
possibly at a lower cost.

         Unlike  forward  foreign  currency  exchange
contracts,  foreign  currency  futures  contracts and
options on foreign  currency  futures  contracts  are
standardized  as to amount  and  delivery  period and
are  traded  on  boards  of  trade  and   commodities
exchanges.  It is  anticipated  that  such  contracts
may  provide  greater  liquidity  and lower cost than
forward foreign currency exchange contracts.

               INVESTMENT RESTRICTIONS
- -----------------------------------------------------

   
CALVERT SOCIAL BALANCED
    

Fundamental Investment Restrictions

         The  Portfolio  has  adopted  the  following
investment  restrictions  which,  together  with  the
foregoing   investment   objectives  and  fundamental
policies,  cannot be changed  without the approval of
the holders of a majority of the  outstanding  shares
of  the  Portfolio.  As  defined  in  the  Investment
Company  Act of 1940,  this  means the  lesser of the
vote of (a) 67% of the shares of the  Portfolio  at a
meeting  where  more  than  50%  of  the  outstanding
shares  are  present  in  person  or by  proxy or (b)
more  than  50%  of  the  outstanding  shares  of the
Portfolio.  Shares  have  equal  rights as to voting,
except that only shares of a Portfolio  are  entitled
to vote on  matters  affecting  only  that  Portfolio
(such as changes in  investment  objective,  policies
or restrictions).

The Portfolio may not:

         1.       Issue  senior   securities
         (except  that it may  borrow  money
         as  described  in   restriction  11
         below).
         2.       With  respect  to at least
         75%  of  the  value  of  its  total
         assets,  invest more than 5% of its
         total  assets  in  the   securities
         (other  than  securities  issued or
         guaranteed  by  the  United  States
         Government   or  its   agencies  or
         instrumentalities)   of   any   one
         issuer    (including     repurchase
         agreements with any one bank).
         3.       Purchase  more than either
         (1) 10% in principal  amount of the
         outstanding  debt  securities of an
         issuer,   or   (ii)   10%   of  the
         outstanding  voting  securities  of
         an   issuer,   except   that   such
         restrictions  shall  not  apply  to
         securities  issued or guaranteed by
         the  United  States  Government  or
         its agencies or instrumentalities.
         4.       Invest  more  than  25% of
         its total assets in the  securities
         of  issuers  primarily  engaged  in
         the same industry.  For purposes of
         this    restriction,    gas,    gas
         transmission,  electric, water, and
         telephone  utilities  each  will be
         considered  a  separate   industry.
         This  restriction does not apply to
         obligations  of  domestic  branches
         of  domestic  banks or savings  and
         loan     associations     or     to
         obligations  issued  or  guaranteed
         by the  United  States  Government,
         its agencies or instrumentalities.
         5.       Invest  in  companies  for
         the purpose of  exercising  control
         (along or  together  with the other
         Portfolios).
         6.       Purchase   securities   of
         other     investment     companies,
         [except   in   connection   with  a
         trustee's/director's       deferred
         compensation   plan,   as  long  as
         there   is   no    duplication   of
         advisory   fees;   or]   except  in
         connection     with    a    merger,
         consolidation,    acquisition    or
         reorganization,  or by  purchase in
         the open  market of  securities  of
         closed-end   investment   companies
         where no  underwriter  or  dealer's
         commission  or  profit,  other than
         customary broker's  commission,  is
         involved,       if      immediately
         thereafter   the  Portfolio   would
         own: (a)  securities  of investment
         companies   having   an   aggregate
         value  in  excess  of 10%  of  such
         Portfolio's total assets;  (b) more
         than 3% of the  outstanding  voting
         stock  of the  investment  company;
         or    (c)    securities    of   the
         investment    company   having   an
         aggregate  value in excess of 5% of
         the Portfolio's total assets.
         7.       Purchase      or      sell
         interests  in  oil,  gas  or  other
         mineral  exploration or development
         programs,  commodities,   commodity
         contracts,   real  estate  mortgage
         loans,  except that each  Portfolio
         may purchase  securities of issuers
         which  invest or deal in any of the
         above,   and   except   that   each
         Portfolio  may invest in securities
         that are  secured by real estate or
         real   estate    mortgages.    This
         restriction   does  not   apply  to
         obligations  issued  or  guaranteed
         by the  United  States  Government,
         its agencies or instrumentalities.
         8.       Purchase  any   securities
         on   margin    (except   that   the
         Portfolio     may    obtain    such
         short-term   credit   as   may   be
         necessary   for  the  clearance  of
         purchases  and  sales of  portfolio
         securities)  or make short sales of
         securities   or  maintain  a  short
         position.
         9.       Make   loans,   except  as
         provided  in (10)  below or through
         the  purchase  of   obligations  in
         private  placements  or by entering
         into  repurchase   agreements  (the
         purchase     of     publicly-traded
         obligations    are    not   to   be
         considered the making of a loan).
         10.      Lend  its   securities  in
         excess of 10% of its total  assets,
         provided  that such  loan  shall be
         made   in   accordance   with   the
         guidelines  set forth  below  under
         "Lending of Portfolio Securities."
         11.      Borrow  amounts  in excess
         of 10% of its  total  assets  taken
         at market  value at the time of the
         borrowing,   and  then   only  from
         banks as a  temporary  measure  for
         extraordinary      or     emergency
         purposes,  or  to  meet  redemption
         requests   that   might   otherwise
         require  the  untimely  disposition
         of   securities,    and   not   for
         investment  or  leveraging,  except
         by    entering     into     reverse
         repurchase  agreements.  Borrowings
         and reverse  repurchase  agreements
         combined  will not  exceed 1/3 of a
         Portfolio'   total   assets,    and
         additional  investments will not be
         made by a Portfolio  if  borrowings
         exceed 5% of its total assets.
         12.      Mortgage,          pledge,
         hypothecate   or  in   any   manner
         transfer,     as    security    for
         indebtedness,  any securities owned
         or held by  such  Portfolio  except
         as may be necessary  in  connection
         with reverse repurchase  agreements
         or  borrowings  mentioned  in  (11)
         above,  and then  such  mortgaging,
         pledging or  hypothecating  may not
         exceed   10%  of  such   Portfolio'
         total  assets.  In order to  comply
         with certain state  statutes,  such
         Portfolio  will not, as a matter of
         operating policy, mortgage,  pledge
         or  hypothecate  its  securities to
         the  extent  that at any  time  the
         percentage  of the value of pledged
         securities  plus the maximum  sales
         charge   will  exceed  10%  of  the
         value of such  Portfolio  shares at
         the maximum offering price.
         13.      Underwrite  securities  of
         other  issuers  except  insofar  as
         the  Portfolio  may  be  deemed  an
         underwriter  under  the  Securities
         Act of 1933 in  selling  shares  of
         each  Portfolio,  and  except as it
         may be  deemed  such  in a sale  of
         restricted securities.
         14.      Write,  purchase  or  sell
         puts,    calls   or    combinations
         thereof,  except in connection with
         when-issued securities.
         15.      Invest  in  securities  of
         foreign  issuers  if at the time of
         acquisition  more  than  10% of its
         total  assets taken at market value
         at  the  time  of  the  investment,
         would   be    invested    in   such
         securities.
         16.      Participate   on  a  joint
         (or a joint and  several)  basis in
         any trading  account in  securities
         (but  this  does not  prohibit  the
         "bunching"  of orders  for the sale

the value of such  investment,  together  with  prior
investments  of that  Portfolio in the  securities of
such  issuer,  would  exceed  10% of the value of the

Fundamental Investment Restrictions

         The  Portfolios  have adopted the  following
investment  restrictions  which,  together  with  the
foregoing   investment   objectives  and  fundamental
policies,  cannot be changed  without the approval of
the holders of a majority of the  outstanding  shares
of  the  Portfolio.  As  defined  in  the  Investment
Company  Act of 1940,  this  means the  lesser of the
vote of (a) 67% of the shares of the  Portfolio  at a
meeting  where  more  than  50%  of  the  outstanding
shares  are  present  in  person  or by  proxy or (b)
more  than  50%  of  the  outstanding  shares  of the
Portfolio.  Shares  have  equal  rights as to voting,
except that only shares of a Portfolio  are  entitled
to vote on  matters  affecting  only  that  Portfolio
(such as changes in  investment  objective,  policies
or restrictions).

The Portfolios may not:

         1.       With  respect  to  75%  of
         assets,  purchase securities of any

         or   guaranteed   by,   the  United
         States Government,  its agencies or
         instrumentalities)    if,    as   a
         result,  more  than 5% of the value
         of  its  total   assets   would  be
         invested  in   securities  of  that
         issuer.
         2.       Concentrate  more than 25%
         of the  value of its  assets in any
         one  industry;  provided,  however,
         that  there is no  limitation  with
         respect    to     investments    in
         obligations  issued  or  guaranteed
         by the United States  Government or
         its           agencies          and
         instrumentalities,  and  repurchase

         respect  to  investments  in  money
         market instruments of banks.

         the outstanding  voting  securities
         of any issuer.

         through   the   purchase  of  money
         market  instruments  and repurchase
         agreements  or by the  purchase  of
         bonds,  debentures  or  other  debt
         securities.  The  purchase  by  the
         Portfolio  of all or a  portion  of
         an issue of publicly  or  privately
         distributed   debt  obligations  in
         accordance   with  its   investment
         objective,       policies       and
         restrictions,  shall not constitute
         the making of a loan.
         5.       Underwrite  the securities
         of  other  issuers,  except  to the
         extent that in connection  with the
         disposition    of   its   portfolio
         securities,  the  Portfolio  may be
         deemed to be an underwriter.
         6.       Purchase  from  or sell to
         any  of  the  Fund's   officers  or
         Directors,  or firms  of which  any
         of   them    are    members,    any
         securities   (other  than   capital
         stock of the  Portfolio),  but such
         persons   or   firms   may  act  as

         customary commissions.
         7.       Borrow money,  except from
         banks for  temporary  or  emergency
         purposes   and  then   only  in  an
         amount  up to 10% of the  value  of
         the  Portfolio's  total  assets and
         except  by   engaging   in  reverse
         repurchase  agreements;   provided,
         however,  that it may  only  engage
         in  reverse  repurchase  agreements
         so long as,  at the time it  enters
         into    a    reverse     repurchase
         agreement,  the aggregate  proceeds
         from      outstanding       reverse
         repurchase  agreements,  when added
         to  other  outstanding   borrowings
         permitted by this  section,  do not
         exceed  33 1/3% of the  Portfolio's
         total  assets.  In order to  secure
         any   permitted    borrowings   and
         reverse    repurchase    agreements
         under this  section,  the Portfolio
         may     pledge,     mortgage     or
         hypothecate its assets.
         8.       Make   short    sales   of
         securities    or    purchase    any
         securities  on margin  except  that
         the   Portfolio   may  obtain  such
         short-term   credits   as   may  be
         necessary   for  the  clearance  of
         purchases and sales of  securities.

         Portfolio     of     initial     or
         maintenance  margin  in  connection
         with  financial  futures  contracts
         or related options  transactions is

         9.       Write,  purchase  or  sell
         puts,    calls   or    combinations
         thereof  except that the  Portfolio
         may   (a)   write   exchange-traded
         covered  call  options on portfolio
         securities  and enter into  closing
         purchase  transactions with respect
         to such options,  and the Portfolio

         premiums  on all  outstanding  call
         and put  options  do not  exceed 5%
         of  its  total  assets,  and  enter
         into closing sale  transaction with

Nonfundamental Investment Restrictions

   
         Calvert     Social    Money    Market    and

operating    (i.e.,    non-fundamental)    investment
policies  and  restrictions  which may be  changed by
the   Board   of   Directors   without    shareholder
approval. None of these Portfolios may:

         1.       Purchase          illiquid
         securities  if more  than  10% (15%
         for  International  Equity)  of the
         value of a  Portfolio's  net assets
         would   be    invested    in   such
         securities.  A  Portfolio  may  buy
         and  sell  securities  outside  the
         U.S. that are not  registered  with
         the SEC or marketable in the U.S.

         For    purposes    of    the     Portfolio's
concentration  policy  contained in restriction  (2),
above,  the  Fund  intends  to  comply  with  the SEC
staff position that  securities  issued or guaranteed
as to principal  and  interest by any single  foreign
government   are   considered  to  be  securities  of
issuers in the same industry.
    

         Any investment  restriction  that involves a
maximum  percentage  of securities or assets will not
be  considered  to be violated  unless an excess over
the applicable  percentage  occurs  immediately after
an   acquisition  of  securities  or  utilization  of
assets,  and  the  excess  is  attributable  to  that
event.

         Portfolio),  but  such  persons  or
         firms  may act as  brokers  for the
         Fund for customary commissions.
         6.       Except  as   required   in
         connection     with     permissible
         options,   futures  and   commodity
         activities   of   the    Portfolio,
         invest  in  commodities,  commodity
         futures  contracts,  real estate or
         real estate  limited  partnerships,
         although    it   may    invest   in
         securities  which  are  secured  by
         real    estate   or   real   estate
         mortgages    and    securities   of
         issuers  which  invest  or  deal in
         commodities,   commodity   futures,
         real    estate   or   real   estate
         mortgages  and provided that it may
         purchase   or  sell   stock   index
         futures,  foreign currency futures,
         interest  rate  futures and options
         thereon.
         7.       Invest  in the  shares  of
         other investment companies,  except
         as  permitted  by the  1940  Act or
         other  applicable  law, or pursuant
         to Calvert's  nonqualified deferred
         compensation  plan  adopted  by the
         Board  of  Directors  in an  amount
         not to exceed  10% or as  permitted
         by law.
         8.       Purchase  more than 10% of
         the outstanding  voting  securities
         of any issuer.

Nonfundamental Investment Restrictions

   
         Mid Cap Growth  has  adopted  the  following
operating    (i.e.,     nonfundamental)    investment
policies  and  restrictions  which may be  changed by
the   Board   of   Directors   without    shareholder
approval. The Fund may not:
    

         9.       Invest,  in the aggregate,
         more than 15% of its net  assets in
         illiquid  securities.  Purchases of
         securities  outside  the U.S.  that
         are not registered  with the SEC or
         marketable  in the U.S. are not per
         se illiquid.
         10.      Make   short    sales   of
         securities    or    purchase    any
         securities  on margin  except  that
         the    Fund   may    obtain    such
         short-term   credits   as   may  be
         necessary   for  the  clearance  of
         purchases and sales of  securities.
         The  depositor  payment by the Fund
         of  initial or  maintenance  margin
         in   connection    with   financial
         futures    contracts   or   related
         options    transactions    is   not
         considered   the   purchase   of  a
         security on margin.
         11.      Borrow money,  except from
         banks for  temporary  or  emergency
         purposes,   and  then  only  in  an
         amount not to exceed  one-third  of
         the  Portfolio's  total assets,  or
         as  permitted  by law.  In order to
         secure  any  permitted   borrowings
         under this  section,  the Portfolio
         may     pledge,     mortgage     or
         hypothecate its assets.

         For    purposes    of    the     Portfolio's
concentration  policy  contained in restriction  (2),
above,  the  Fund  intends  to  comply  with  the SEC
staff position that  securities  issued or guaranteed
as to principal  and  interest by any single  foreign
government   are   considered  to  be  securities  of
issuers in the same industry.

         Any  investment  restriction  which involves
a maximum  percentage  of  securities or assets shall
not be  considered  to be  violated  unless an excess
over the  applicable  percentage  occurs  immediately
after an  acquisition  of securities  or  utilization
of assets and results therefrom.

Virginia Law Restrictions

         In addition to the  investment  restrictions
described  above,  the  Portfolios  will  comply with
restrictions   contained  in  the  current   Virginia
Insurance  Laws  in  order  that  the  assets  of the
Variable   Accounts  may  be  invested  in  Portfolio
shares.   The  Virginia   Insurance   Laws  currently
permit the  Variable  Accounts to invest in Portfolio
shares   without    restricting    the    Portfolios'
investments.    However,    those   laws   or   their
interpretation may change.

Lending of Portfolio Securities

         Subject  to  the   investment   restrictions
above,   a  Portfolio  may  lend  its  securities  to
brokers,   dealers  and  financial  institutions  and
receive   as   collateral   cash  or  United   States
Treasury  securities.  At all times while the loan is
outstanding,   collateral   will  be   maintained  in
amounts  equal  to  at  least  100%  of  the  current
market  value  of the  loaned  securities.  Any  cash
collateral    will   be   invested   in    short-term
securities,  which will  increase the current  income
the  Portfolio  lending  its  securities.  Such loans
will be  terminable  by the Portfolio at any time and
will  not be made  to  affiliates  of the  Portfolio.
The  Portfolio  will have the right to regain  record
ownership   of   loaned    securities   to   exercise
beneficial    rights    such   as   voting    rights,
subscription   rights   and   rights  to   dividends,
interest or other  distributions.  The  Portfolio may
pay  reasonable  fees to  persons  unaffiliated  with
the  Portfolio for arranging  loans.  The  dividends,
interest  and  other  distributions  received  by the
Portfolio  on loaned  securities,  for tax  purposes,
may  be  treated  as  income  other  than   qualified
income for purposes of the 90% test  discussed  below
under  "Taxes." The  Portfolios  intend to lend their
securities  only to the  extent  that  such  activity
does  not  jeopardize   their   qualification   as  a
regulated    investment    company    under   certain
provisions  of the Internal  Revenue  Code.  Loans of
securities  will  be  made  only to  firms  that  the
Investment Advisor deems  creditworthy.  However,  as
with any  extensions  of  credit,  there are risks of
delay in  recovery  and even  loss of  rights  in the
collateral  should the  borrower of  securities  fail
financially.

When-Issued and Delayed Delivery Securities

         From time to time,  in the  ordinary  course
of business,  each Portfolio may purchase  securities
on a when-issued  or delayed  delivery  basis -- that
is,  delivery  and  payment can take place a month or
more  after  the  date  of  the   transactions.   The
securities  purchased  in this  manner are subject to
market  fluctuation  and no  interest  accrues to the
purchaser   during  this   period.   At  the  time  a
Portfolio  makes a commitment to purchase  securities
on a  when-issued  or  delayed  delivery  basis,  the
price is fixed  and the  Portfolio  will  record  the
transaction  and thereafter  reflect the value,  each
day,  of the  security in  determining  the net asset
value of the  Portfolio.  At the time of  delivery of
the  securities,  the  value may be more or less than
the purchase price.

         The  Portfolio  will enter  commitments  for
when-issued  or  delayed  delivery   securities  only
when  it   intends   to   acquire   the   securities.
Accordingly,   each   Portfolio   will   establish  a
segregated  account  with the  Portfolio's  custodian
bank  in  which  it  will   maintain   cash  or  cash
equivalents or other  portfolio  securities  equal in
value  to   commitments   for  such   when-issued  or
delayed   delivery   securities.   Subject   to  this
restriction,   a   Portfolio   may   purchase   these
securities without limit.

- -----------------------------------------------------
            INVESTMENT SELECTION PROCESS
- -----------------------------------------------------

   
         Investments  in the  Portfolios are selected
on the basis of their  ability to  contribute  to the
dual  objective of the  Portfolios.  The Advisors and
Subadvisors   have   each   developed   a  number  of
techniques   for   evaluating   the   performance  of
issuers in each of these areas.  The primary  sources
of information  are reports  published by the issuers
themselves,  the reports of public agencies,  and the
reports  of  groups  which  monitor   performance  in
particular  areas.  These sources of information  are
sometimes   augmented   with  direct   interviews  or
written  questionnaires  addressed to the issuers. It
should be  recognized,  however,  that  there are few
generally  accepted  measures by which achievement in
these    areas   can   be   readily    distinguished;
therefore,  the  development of suitable  measurement
techniques  is  largely  within  the  discretion  and
judgment  of  the  Advisors  and  Subadvisors  of the
Portfolio.

         It  should  be noted  that  the  Portfolios'
social  criteria  tend to limit the  availability  of
investment   opportunities  more  than  is  customary
with other  investment  companies.  The  Advisor  and
Subadvisors,   however,   believe   that   there  are
sufficient  investment  opportunities  to permit full
investment    among    issuers   that   satisfy   the
Portfolios' social investment objective.
    

         To the greatest  extent  possible,  the same
social   criteria  is  applied  to  the  purchase  of
non-equity   securities  as  to  equity  investments.
Bank  certificates  of  deposit,   commercial  paper,
repurchase   agreements,   and  corporate  bonds  are
judged in the same way as a  prospective  purchase of
the bank's or issuing  company's  common  stock.  The
Portfolios may invest,  however,  in  certificates of
deposit of banks and  savings  and loan  associations
in which the  Portfolios  would not otherwise  invest
because such  institutions  have assets of $1 billion
or less,  but  generally  only to the extent all such
investments  are fully  insured  as to  principal  by
the Federal Deposit Insurance Corporation.

         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.    Certain    obligations    issued    or
guaranteed   by   a   U.S.   Government   agency   or
instrumentality  are  supported by the full faith and
credit  of  the  U.S.   Government.   These   include
obligations   issued  by  the   Export-Import   Bank,
Farmers  Home  Administration,   Government  National
Mortgage   Association,   Postal  Service,   Merchant
Marine,  and  Washington  Metropolitan  Area  Transit
Authority.  The  Portfolios  may also invest in other
U.S.    Government    agency    or    instrumentality
obligations  which are  supported  only by the credit
of the agency or  instrumentality  and may be further
supported  by the right of the issuer to borrow  from
the   U.S.   Treasury.   Such   obligations   include
securities  issued  by  the  Bank  for  Cooperatives,
Federal   Intermediate   Credit  Bank,  Federal  Land
Bank,  Federal  Home  Loan  Bank,  Federal  Home Loan
Mortgage  Corporation,  and Federal National Mortgage
Association.

- -----------------------------------------------------
                 PORTFOLIO TURNOVER
- -----------------------------------------------------

   
         Each  Portfolio  has  a  different  expected
annual   rate  of   portfolio   turnover.   Portfolio
turnover   is   defined   as  the  lesser  of  annual
purchases  or sales of portfolio  securities  divided
by  the   monthly   average   of  the  value  of  the
Portfolios'    securities    (excluding    from   the
computation all securities,  including options,  with
maturities  or  expiration   dates  at  the  time  of
acquisition  of one  year or  less).  A high  rate of
portfolio       turnover      generally      involves
correspondingly    greater    brokerage    commission
expenses,   which  must  be  borne  directly  by  the
Portfolio.    Notwithstanding   increased   brokerage
commission  expenses,   particular  holdings  may  be
sold  at  any   time  if   investment   judgment   or
Portfolio operations make a sale advisable.

         For the fiscal years 1995,  1996,  and 1997,
the  portfolio  turnover  rates  for  Calvert  Social
Balanced  were  163%,  99%,  and 905%,  respectively.
For the same time  periods,  the  portfolio  turnover
rates for  Calvert  Social Mid Cap Growth  were 135%,
124%,  and  96%,  respectively.  For  the  same  time
periods,   the  portfolio   turnover  rates  for  the
International  Equity  series were 90%, 85%, and 35%,
respectively.  For the period from  inception  (March
1, 1995)  through  December 31, 1995,  and for fiscal
year 1996,  and 1997,  the portfolio  turnover  rates
for Small  Cap  Growth  were  223%,  120%,  and 292%,
respectively.

         No   Portfolio    turnover   rate   can   be
calculated  for Calvert  Social  Money  Market due to
the short  maturities of the  instruments  purchased.
Portfolio  turnover  should  not affect the income or
net  asset  value  of  Calvert  Social  Money  Market
because   brokerage   commissions  are  not  normally
charged  on the  purchase  or  sale of  money  market
instruments.
    

- -----------------------------------------------------
          PURCHASE AND REDEMPTION OF SHARES
- -----------------------------------------------------

         The  Portfolios   continuously  offer  their
shares at prices  equal to the  respective  net asset
values of the  Portfolios  determined  in the  manner
set forth  below  under  "Determination  of Net Asset
Value." The  Portfolios  offer their shares,  without
sales   charge,   only  for   purchase   by   various
Insurance   Companies   for   allocation   to   their
Variable  Accounts.  It is  conceivable  that  in the
future  it may be  disadvantageous  for both  annuity
Variable   Accounts  and  life   insurance   Variable
Accounts  of  different   Insurance   Companies,   to
invest  simultaneously  in the  Portfolios,  although
currently  neither the  Insurance  Companies  nor the
Portfolio  foresee any such  disadvantages  to either
variable  annuity or variable life  insurance  policy
holders of any  Insurance  Company.  The  Portfolio's
Board of  Directors  intends  to  monitor  events  in
order to  identify  any  material  conflicts  between
such  policyholders  and to determine what action, if
any, should be taken in response to any conflicts.

         The  Portfolios  are  required to redeem all
full and  fractional  shares for cash. The redemption
price is the net  asset  value per  share,  which may
be more or less  than the  original  cost,  depending
on  the  investment   experience  of  the  Portfolio.
Payment for shares  redeemed  will  generally be made
within  seven days after  receipt of a proper  notice
of  redemption.  The  right to  redeem  shares  or to
receive  payment with respect to any  redemption  may
only be  suspended  for any period  during  which (a)
trading   on  the  New   York   Stock   Exchange   is
restricted  as  determined  by  the   Securities  and
Exchange  Commission,  or the  Exchange is closed for
other than  weekends and  holidays;  (b) an emergency
exists,   as   determined  by  the   Securities   and
Exchange  Commission,  as a result of which  disposal
of Portfolio  securities or  determination of the net
asset value of a  Portfolio  is not  practicable;  or
(c) the Securities  and Exchange  Commission by order
permits    postponement   for   the   protection   of
shareholders.

- -----------------------------------------------------
          DETERMINATION OF NET ASSET VALUE
- -----------------------------------------------------

   
         The net  asset  value of the  shares of each
Portfolio  of the Fund is  determined  by adding  the
values  of all  securities  and  other  assets of the
Portfolio,   subtracting  liabilities  and  expenses,
and   dividing   by  the  number  of  shares  of  the
Portfolio  outstanding.  Expenses are accrued  daily,
including  the  investment   advisory  fee.   Calvert
Social Money  Market  attempts to maintain a constant
net  asset  value of $1.00 per  share;  the net asset
values  of  Calvert  Social  Balanced,  International
Equity,   Small  Cap   Growth   and  Mid  Cap  Growth
fluctuate  based on the  respective  market  value of
the  Portfolio's  investments.  The net  asset  value
per  share of each of the  Portfolios  is  determined
every  business  day as of the  close of the  regular
session  of the New York  Stock  Exchange  (generally
4:00 p.m.  Eastern time),  and at such other times as
may be necessary or  appropriate.  The  Portfolios do
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, Dr.  Martin  Luther King,  Jr. Day, Good Friday,
Memorial   Day,    Independence   Day,   Labor   Day,
Thanksgiving    Day,   and   Christmas    Day.   Each
Portfolio's  net asset value per share is  determined
by dividing  that  Portfolio's  total net assets (the
value of its  assets  net of  liabilities,  including
accrued  expenses  and fees) by the  number of shares
outstanding.

         The  assets  of  Calvert  Social   Balanced,
International  Equity,  Mid Cap  Growth and Small Cap
Growth  are valued as  follows:  (a)  securities  for
which market  quotations  are readily  available  are
valued  at  the  most  recent  closing  price,   mean
between bid and asked price,  or yield  equivalent as
obtained  from  one or more  market  makers  for such
securities;  (b) securities  maturing  within 60 days
may be  valued at cost,  plus or minus any  amortized
discount  or premium,  unless the Board of  Directors
determines  such method not to be  appropriate  under
the  circumstances;  and (c) all other securities and
assets for which  market  quotations  are not readily
available  will be fairly  valued by the  Advisor  in
good  faith  under  the  supervision  of the Board of
Directors.  Securities  primarily  traded on  foreign
securities  exchanges  are  generally  valued  at the
preceding   closing   values   on  their   respective
exchanges  where  primarily  traded.  Equity  options
are  valued at the last  sale  price  unless  the bid
price is  higher  or the  asked  price is  lower,  in
which   event  such  bid  or  asked  price  is  used.
Exchange  traded fixed  income  options are valued at
the last sale price  unless  there is no sale  price,
in which  event  current  prices  provided  by market
makers  are  used.   Over-the-counter   fixed  income
options  are  valued   based  upon   current   prices
provided  by market  makers.  Financial  futures  are
valued at the settlement  price  established each day
by the board of trade or  exchange  on which they are
traded.  Because  of the need to obtain  prices as of
the   close   of   trading   on   various   exchanges
throughout   the  world,   the   calculation  of  the
Portfolio's  net asset  value does not take place for
contemporaneously   with  the  determination  of  the
prices of U.S.  portfolio  securities.  For  purposes
of  determining  the net asset  value all  assets and
liabilities  initially  expressed in foreign currency
values will be converted  into United  States  dollar
values  at the  mean  between  the  bid  and  offered
quotations of such  currencies  against United States
dollars at last quoted by any recognized  dealer.  If
an  event  were  to  occur  after  the  value  of  an
investment  was so  established  but  before  the net
asset  value  per  share  was  determined  which  was
likely to  materially  change  the net  asset  value,
then  the  instrument  would  be  valued  using  fair
value   consideration   by  the  Directors  or  their
delegates.

         Calvert   Social  Money   Market'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.

         Rule 2a-7 under the  Investment  Company Act
of  1940  permits   Calvert   Social  Money  Market's
assets  to  be  valued  at  amortized   cost  if  the
Portfolio   maintains   a   dollar-weighted   average
maturity  of 90  days  or  less  and  only  purchases
obligations  having remaining  maturities of thirteen
months or less.  Rule 2a-7  requires,  as a condition
of its use,  that Calvert  Social Money Market invest
only in  obligations  determined  by the Directors to
be of good  quality  with  minimal  credit  risks and
requires  the   Directors  to  establish   procedures
designed  to  stabilize,  to  the  extent  reasonably
possible,   the   Portfolio's   price  per  share  as
computed  for the  purpose  of sales and  redemptions
at  $1.00.  Such  procedures  include  review  of the
Portfolio's  investment  holdings  by the  Directors,
at such  intervals as they may deem  appropriate,  to
determine  whether  the  Portfolio's  net asset value
calculated by using  available  market  quotations or
equivalents  deviates  from $1.00 per share  based on
amortized  cost.  If such  deviation  exceeds  0.50%,
the  Directors  will  promptly  consider what action,
if  any,  will  be   initiated.   In  the  event  the
Directors  determine  that a deviation  exists  which
may  result  in  material  dilution  or other  unfair
results to  investors or existing  shareholders,  the
Directors  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.
    

- -----------------------------------------------------
                        TAXES
- -----------------------------------------------------

   
         In 1997  the  Portfolios  qualified,  and in
1998  the   Portfolios   intend  to  qualify,   as  a
"regulated  investment  company" under the provisions
of  Subchapter  M of the  Internal  Revenue Code (the
"Code").  To qualify  for  treatment  as a  regulated
investment   company,   each  Portfolio  must,  among
other   things,   have  assets   that  meet   certain
requirements  specified  in the  Code and  derive  in
each  taxable  year at least 90% of its gross  income
from  dividends,  interest,  payments with respect to
securities  loans,  and gains (without  deduction for
losses) from the sale or other  disposition  of stock
or   securities.   If   the   Portfolio   distributes
substantially  all of its net  ordinary  and  capital
gains   income,   the   Portfolio   qualifies   as  a
regulated  investment  company and is  relieved  from
paying  federal  income tax on  amounts  distributed.
Each Portfolio will be taxed as a separate entity.
    

         Since  the  shareholders  of the  Portfolios
are   Insurance   Companies,    this   Statement   of
Additional    Information    does   not   contain   a
discussion  of the  federal  income tax  consequences
at   the   shareholder    level.    For   information
concerning   the   federal   tax    consequences   to
purchasers  of  annuity or life  insurance  policies,
see the prospectus for the policies.

        CALCULATION OF YIELD AND TOTAL RETURN
- -----------------------------------------------------

   
Calvert Social Money Market: Yield

         From  time  to  time  Calvert  Social  Money
Market   advertises   its  "yield"   and   "effective
yield."  Both yield  figures are based on  historical
earnings  and are not  intended  to  indicate  future
performance.  The  "yield"  of Calvert  Social  Money
Market  refers to the actual  income  generated by an
investment  in the Portfolio  over a particular  base
period of time.  If the base  period is less than one
year,  the yield is then  "annualized."  That is, the
net  change,  exclusive  of capital  changes,  in the
value of a share  during  the base  period is divided
by the net asset  value  per  share at the  beginning
of the period,  and the result is  multiplied  by 365
and  divided  by the  number  of  days  in  the  base
period.    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.  Calvert
Social  Money  Market's   "effective   yield"  for  a
seven-day  period is its annualized  compounded 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, 1997,  Calvert  Social Money  Market's  yield was
5.35% and its effective yield was 5.50%.
    

         The  yield  of the  Money  Market  Portfolio
will  fluctuate  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   of   account.   Yield   during   any
particular  time period  should not be  considered an
indication of future yield.  It is,  however,  useful
in  evaluating a Portfolio's  performance  in meeting
its investment objective.

   
Calvert Social Balanced,  International  Equity,  Mid
Cap Growth  and Small Cap  Growth:  Total  Return and
Other Quotations
    

         Calvert   Social   Balanced,   International
Equity,  Mid Cap  Growth  and  Small Cap  Growth  may
each  advertise   "total  return."  Total  return  is
computed  by  taking  the  total   number  of  shares
purchased  by  a  hypothetical   $1,000   investment,
adding all  additional  shares  purchased  within the
period with reinvested  dividends and  distributions,
calculating  the value of those  shares at the end of
the period,  and  dividing  the result by the initial
$1,000  investment.  For  periods  of more  than  one
year,  the  cumulative  total return is then adjusted
for the  number of  years,  taking  compounding  into
account,  to  calculate  average  annual total return
during that period.

         Total  return is computed  according  to the
following formula:

                   P(1 + T)n = ERV

where  P  =  a   hypothetical   initial   payment  of
$10,000;  T = total return;  n = number of years; and
ERV = the ending  redeemable  value of a hypothetical
$10,000   payment  made  at  the   beginning  of  the
period.  Total return is  historical in nature and is
not intended to indicate  future  performance.  Total
return for the Portfolios  for the periods  indicated
are as follows:

            INVESTMENT ADVISORY AGREEMENT
- -----------------------------------------------------

   
         The   current   Investment   Agreement   was
entered  into  on  June  30,  1992.   Unless  earlier
terminated,  the  Agreement  will  remain  in  effect
indefinitely  if approved  annually  (a) by the Board
of  Directors  of the  Fund or by a  majority  of the
outstanding  shares  of the  Portfolio,  including  a
majority   of  the   outstanding   shares   of   each
Portfolio,  and (b) by a  majority  of the  Directors
who are not parties to such  contract  or  interested
persons  (as  defined by the  Investment  Company Act
of 1940)  of any such  party.  The  Agreement  is not
assignable and may be terminated  without  penalty on
60 days'  written  notice  at the  option  of  either
party  or by  the  vote  of the  shareholders  of the
Portfolio.
    

         The Investment  Advisory  Agreement provides
that  the   Advisor   will  not  be   liable  to  the
Portfolio or to any  shareholder  or policy owner for
any error of  judgment  or  mistake of law or for any
loss   suffered   by   the   Portfolio   or  by   any
shareholder  or  policy  owner  in  connection   with
matters to which the  Investment  Advisory  Agreement
relates,   except  a  loss   resulting  from  willful
misfeasance,   bad  faith,   gross   negligence,   or
reckless  disregard  on the  part of the  advisor  in
the performance of its duties thereunder.

   
         For the Fund's  fiscal years ended  December
31, 1995,  1996, and 1997,  Calvert  Social  Balanced

Calvert Social Money Market paid  investment  adviser
fees    of    $27,591,    $24,348,    and    $30,309,
respectively.     For    1995,     Calvert     Social
International  Equity paid CAM $93,418,  and received
expense   reimbursements  from  CAM  of  $36,720.  In

Securities Activities of the Investment Advisor

         Securities  held by the  Portfolios may also
be held by the Insurance  Companies,  their  separate
accounts  or mutual  funds  for which the  Investment
Advisor  or  a  Subadvisor   acts  as  an  investment
advisor.  Because of different investment  objectives
or  other  factors,  any of  these  parties  may  buy
shares  of the  Portfolios  when  one or  more  other
clients   are  selling   the  same   security.   Such
transactions   will  be  done  in  a  manner   deemed
equitable  to all  parties.  To the extent  that such
transactions  increase  the demand for a  Portfolio's
shares, there may be an effect on share prices.

         When  deemed to be in the best  interest  of
the   Portfolios,    the   Investment   Advisors   or
Subadvisors  may aggregate the securities  with those
to  be  sold  or  purchased  for  other  accounts  or
companies  in order  to  obtain  favorable  execution
and  low  brokerage   commissions.   In  that  event,
allocation  of the  securities  purchased or sold, as
well as the  expenses  incurred  in the  transaction,
will   be   made  by  the   Investment   Advisor   or
Subadvisor  in the  manner  it  considers  to be most
equitable   and   consistent   with   its   fiduciary
obligations  to  the  Portfolios  and  to  the  other
accounts or  companies  involved.  In some cases this
procedure  may  adversely  affect  the  size  of  the
position obtainable for a Portfolio.

Payment of Expenses

   
         In  addition  to  the  portfolio  management
and investment  advice  described  above, CAM also is
obligated  to  perform  certain   administrative  and
management  services  and to provide  all  executive,
administrative,    clerical   and   other   personnel
necessary  to operate  the  Portfolio  and to pay the
salaries of all these  persons.  CAM will furnish the
Portfolio   with  office   space,   facilities,   and
equipment  and pay the  day-to-day  expenses  related
to the  operation  and  maintenance  of  such  office
space,  facilities and equipment.  Legal,  accounting
and all other expenses  incurred in the  organization
of the  Portfolio,  including  costs  of  registering
under federal and state  securities  laws,  will also
be  paid  by  CAM  except   with   respect  to  those
administrative    services    provided   by   Calvert
Administrative  Services  Company to  Calvert  Social
International   Equity,   Calvert   Social   Mid  Cap
Growth,   and   Calvert   Social   Small  Cap  Growth
pursuant    to    their    Administrative    Services
Agreements.

         Expenses   of  the  Fund  will  be   accrued
daily.  Expenses  that the  respective  Portfolios of
the Fund will pay individually  include,  but are not
limited  to  the  following:  brokerage  commissions,
dealer  markups  and other  expenses  incurred in the
acquisition  or   disposition   of  any   securities,
printing costs  (including  the daily  calculation of
net asset value),  interest,  certain taxes,  charges
of  the  custodian  and  transfer  agent,  and  other
expenses  attributable  to  a  particular  Portfolio.
Expenses  which  will  be  allocated  to the  various
Portfolios   on  the   basis   of  the  size  of  the
respective  portfolio,  determined each day,  include
legal and  auditing  fees,  expenses  of  shareholder
and director  meetings,  independent  director  fees,
bookkeeping    expenses    related   to   shareholder
accounts,  insurance  charges,  cost of printing  and
mailing  shareholder  reports  and proxy  statements,
the  cost  to  pay   dividends   and   capital   gain
distributions,  the  costs of  printing  and  mailing
registration  statements,  and  updated  prospectuses
to  current  shareholders,  and the fees of any trade
association  of  which  the  Portfolio  is a  member.
Expenses  resulting from legal actions  involving the
Portfolio   and  any  amount  for  which  it  may  be
obligated to indemnify  its  officers,  directors and
employees,  may  either  be  directly  applicable  to
particular  Portfolios  or  allocated on the basis of
the size of the respective  Portfolios,  depending on
the nature of the legal action.
    

Securities Transactions and Brokerage

         The  Investment  Advisor,  and in some cases
the  Subadvisor,  is  primarily  responsible  for the
investment  decisions  of each  Portfolio,  including
decisions to buy and sell  securities,  the selection
of brokers  and  dealers to effect the  transactions,
the  placing  of  investment  transactions,  and  the
negotiation  of  brokerage  commissions,  if any.  No
Portfolio  has  any   obligation  to  deal  with  any
dealer  or  group  of  dealers  in the  execution  of
transactions  in  Portfolio  securities.  In  placing
orders,  it  is  the  policy  of  each  Portfolio  to
obtain the most  favorable  net results,  taking into
account  various  factors,  including  price,  dealer
spread or  commission,  the size of the  transaction,
and  difficulty  of execution.  While the  Investment
Advisor and  Subadvisors  generally  seek  reasonably
competitive  spreads or  commissions,  the Portfolios
will not  necessarily  be paying the lowest spread or
commission available.

         If the  securities  in  which  a  particular
Portfolio   invests  are  traded   primarily  in  the
over-the-counter  market,  the  Portfolio  will deal,
where  possible,  with the  dealers who make a market
in the securities  involved  unless better prices and
execution  are  available  elsewhere.  These  "market
makers"  usually  act as  principals  for  their  own
account.  On occasion,  the  Portfolios  may purchase
securities  directly  from  the  issuer.   Bonds  and
money market  securities  are  generally  traded on a
net  basis  and  do  not  normally   involve   either
brokerage  commission or transfer taxes.  The cost of
Portfolio   securities   transactions   will  consist
primarily  of  brokerage  commissions  or  dealer  or
underwriter spreads.

         Portfolio  transactions  are  undertaken  on
the basis of their  desirability  from an  investment
standpoint.  Investment  decisions  and the choice of
brokers  and  dealers  are  made by the  Advisor  and
Subadvisors  under the direction and  supervision  of
the Board of Directors.  The Advisor and  Subadvisors
select   broker-dealers   on  the   basis   of  their
professional  capability  and the value  and  quality
of  their   services.   The  Advisor  and  Subadvisor
reserve  the right to place  orders for the  purchase
or sale of portfolio  securities with  broker-dealers
that  have  sold  shares  of the  Portfolios  or that
provide the Portfolios  with  statistical,  research,
or  other  information  and  services.  Although  any
statistical   research  or  other   information   and
services  provided  by  broker-dealers  may be useful
to  the  Advisor  and  the  Subadvisors,  the  dollar
value of such  information  and services is generally
indeterminable,   and  its  availability  or  receipt
does not serve  materially  to reduce  the  Advisor's
or  Subadvisor's   normal   research   activities  or
expenses.

         The  Advisors  and   Subadvisors   may  also
execute   portfolio   transactions  with  or  through
broker-dealers   that   have   sold   shares  of  the
Portfolio.   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
Portfolio  shares sold.  The Advisors or  Subadvisors
may  compensate  such  broker-dealers  at  their  own
expense in  consideration  of their  promotional  and
administrative services.

         The  address  of  directors   and  officers,
unless  otherwise  noted, is 4550 Montgomery  Avenue,
Suite  1000N,  Bethesda,  Maryland  20814.  Directors
and  officers  of the Fund as a group  own less  than
1%  of  the  Fund's  outstanding  shares.   Directors
marked with an *,  above,  are  "interested  persons"
of the Fund,  under  the  Investment  Company  Act of
1940.
         During  fiscal  1997,  directors of the Fund
not  affiliated  with the  Fund's  Advisor  were paid
$638 by  Calvert  Social  Money  Market,  $18,277  by
Calvert  Social  Balanced,  $1,465 by Calvert  Social
International  Equity,  $2,156 by Calvert  Social Mid
Cap  Growth  and $358 by  Calvert  Social  Small  Cap
Growth.   Each  Director  of  the  Fund  who  is  not
affiliated  with the  Advisor  receives a meeting fee
of $750 for each Board  meeting  attended;  such fees
are  allocated  among the  Series  based  upon  their
relative  net  assets.  Directors  not on  any  other
Calvert  Group Fund  Boards  receive an annual fee of
$3,000.
         Directors  of the Fund not  affiliated  with
the  Fund's  Advisor  ("noninterested  persons")  may
elect  to defer  receipt  of all or a  percentage  of
their  annual  fees  and  invest  them in any fund in
the   Calvert    Family   of   Funds    through   the
Directors/Trustees    Deferred    Compensation   Plan
(shown a "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.

                 GENERAL INFORMATION
- -----------------------------------------------------

   
         The Fund was  incorporated  in  Maryland  on
September 27, 1982. The  authorized  capital stock of
the  Fund  consists  of  three  hundred  twenty  five
million  shares  of  stock,  par  value of $1.00  per
share.  The Fund's Board of Directors  may, from time
to  time,   authorize   the  issuance  of  additional
shares  having the  descriptions,  powers and rights,
and    the    qualifications,     limitations,    and
restrictions  thereof,  as the Board of Directors may
determine.  The Board of  Directors  may also  change
the  designation  of any  portfolio  and may increase
or  decrease  the number of shares of any  portfolio,
but may not  decrease  the  number  of  shares of any
Portfolio   below  the   number  of  shares  of  that
portfolio  then  outstanding.  All  shares  of common
stock have equal  voting  rights  (regardless  of the
net asset  value per share)  except  that only shares
of the  respective  portfolio are entitled to vote on
matters  concerning only that portfolio.  Pursuant to
the  Investment  Company  Act of 1940  and the  rules
and   regulations    thereunder,    certain   matters
approved  by a vote of all  shareholders  of the Fund
may   not   be   binding   on   a   portfolio   whose
shareholders  have not  approved  that  matter.  Each
issued  and  outstanding  share  is  entitled  to one
vote and to  participate  equally  in  dividends  and
distributions  declared by the  respective  portfolio
and, upon  liquidation or dissolution,  in net assets
of such portfolio  remaining  after  satisfaction  of
outstanding   liabilities.   The   shares   of   each
portfolio,  when  issued,  will  be  fully  paid  and
non-assessable  and have no  preemptive or conversion
rights.  Holders  of  shares  of  any  portfolio  are
entitled  to redeem  their  shares as set forth above
under   "Purchase  and  Redemption  of  Shares."  The
shares do not have  cumulative  voting rights and the
holders  of more  than 50% of the  shares of the Fund
voting for the  election of  directors  can elect all
of the  directors  of the Fund if they  choose  to do
so and in such  event the  holders  of the  remaining
shares would not be able to elect any directors.
         The Fund's  Board of  Directors  has adopted
a   "proportionate   voting"  policy,   meaning  that
Insurance  Companies  will  vote  all of  the  Fund's
shares,  including  shares  the  Insurance  Companies
hold,  in  return  for  providing  the Fund  with its
capital  and in payment of charges  made  against the
variable    annuity   or   variable   life   separate
accounts,  in proportion  to the votes  received from
contractholders or policyowners.

                      APPENDIX
- -----------------------------------------------------

Corporate Bond Ratings
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.

Commercial Paper Ratings
Moody's Investors Services, Inc.

         A Prime  rating  is the  highest  commercial
paper rating assigned by Moody's  Investors  Service,
Inc.  Issuers rated Prime are further  referred to by
use  of  numbers  1,  2,  and  3 to  denote  relative
strength  within this highest  classification.  Among
the  factors   considered  by  Moody's  in  assigning
ratings  for  an  issuer  are  the   following:   (1)
management;  (2) economic  evaluation of the inherent
uncertain   areas;   (3)   competition  and  customer
acceptance  of products;  (4)  liquidity;  (5) amount
and  quality  of   long-term   debt;   (6)  ten  year
earnings trends;  (7) financial  strength of a parent
company  and the  relationships  which exist with the
issuer;   and  (8)   recognition   by  management  of
obligations  which may be  present  or may arise as a
result   of    public    interest    questions    and
preparations to meet such obligations.

Standard & Poor's Corporation

         Commercial  paper  rated  A  by  Standard  &
Poor's      Corporation     has     the     following
characteristics:  Liquidity  ratios are  better  than
the  industry  average.  Long term senior debt rating
is "A" or better.  In some cases BBB  credits  may be
acceptable.  The  issuer  has  access to at least two
additional  channels  of  borrowing.  Basic  earnings
and cash  flow have an upward  trend  with  allowance
made  for  unusual  circumstances.   Typically,   the
issuer's  industry  is well  established,  the issuer
has a strong  position  within its  industry  and the
reliability    and   quality   of    management    is
unquestioned.  Issuers  rated A are further  referred
to by use of numbers  1, 2, and 3 to denote  relative
strength within this classification.

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 a
person who has been adjudged liable of willful misfeasance, bad faith,
gross negligence, or reckless disregard of 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 directors 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 Articles of Incorporation also provide that
Registrant may purchase and maintain liability insurance on behalf of
any officer, director, 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.

                        DISTRIBUTION AGREEMENT


         This DISTRIBUTION AGREEMENT, dated as of February 25, 1998
by and between EACH CALVERT FUND LISTED IN THE SCHEDULE OF FUNDS
ATTACHED HERETO AS SCHEDULE I (each a "Fund" and together the
"Funds"), as such schedule may, from time to time be amended, and
CALVERT DISTRIBUTORS, INC., a Delaware corporation (the
"Distributor").

         WHEREAS, each Fund is registered as an open-end investment
company under the Investment Company Act of 1940 (the "1940 Act") and
has registered its shares, including shares of its series portfolios
(the "Series"), for sale to the public under the Securities Act of
1933 (the "1933 Act") and various state securities laws;

         WHEREAS, each Fund wishes to retain the Distributor as the
principal underwriter in connection with the offer and sale of shares
of the Series (the "Shares") and to furnish certain other services to
the Series as specified in this Agreement;

         WHEREAS, this contract has been approved by the
Trustees/Directors of each Fund in anticipation of the Distributor's
transfer of its rights to receive the Class B Distribution Fees ( as
defined in the Distribution Plan for Class B and C Shares (the
"Distribution Plan")) and/or Class B contingent deferred sales
charges to a financing party in order to raise funds to cover
distribution expenditures; and

         WHEREAS, the Distributor is willing to act as principal
underwriter and to furnish such services on the terms and conditions
hereinafter set forth;

         NOW, THEREFORE, in consideration of the promises and mutual
covenants herein contained, it is agreed as follows:

         1.       Each Fund hereby appoints the Distributor as
principal underwriter in connection with the offer and sale of its
Shares. The Distributor shall, as agent for each Fund, subject to
applicable federal and state law and the Declaration of Trust or
Articles of Incorporation, and By-laws of the applicable Fund and in
accordance with the representations in the applicable Fund's
Registration Statement and Prospectus, as such documents may be
amended from time to time: (a) promote the Series; (b) enter into
appropriate dealer agreements with other registered broker-dealers to
further distribution of the Shares; (c) solicit orders for the
purchase of the Shares subject to such terms and conditions as the
applicable Fund may specify; (d) transmit promptly orders and
payments for the purchase of Shares and orders for redemption of
Shares to the applicable Fund's transfer agent; and (e) provide
services agreed upon by the applicable Fund to Series shareholders;
provided, however, that the Distributor may sell no Shares pursuant
to this Agreement until the Distributor is notified that a Fund's
Registration Statement under the 1933 Act, authorizing the sale of
such Shares through the Distributor, has become effective. The
Distributor shall comply with all applicable federal and state laws
and offer the Shares on an agency or "best efforts" basis under which
a Fund shall only issue such Shares as are actually sold.

         2.       The public offering price of the Shares shall be
the net asset value ("NAV") per share (as determined by the
applicable Fund) of the outstanding Shares of the Series, plus the
applicable sales charge, if any, as set forth in the Fund's then
current Prospectus. Each Fund shall furnish the Distributor with a
statement of each computation of NAV and of the details entering into
such computation.

         3.       Compensation.

         a.       Distribution Fee.

         i. Class A. In consideration of the Distributor's services
as distributor for the Class A Shares of a Fund, each Fund may pay to
the Distributor the Distribution Fee as set forth in Schedule II to
this Agreement that is payable pursuant to the Fund's Distribution
Plan.

         ii. Class B. In consideration of the Distributor's services
as distributor for the Class B Shares of a Fund, each Fund shall pay
to the Distributor (or its designee or transferee) the Distributor's
Allocable Portion of the Distribution Fee; (as set forth in Schedule
II to this Agreement) that is payable pursuant to the Fund's
Distribution Plan in respect of the Class B Shares of a Fund. For
purposes of this Agreement, the Distributor's "Allocable Portion" of
the Distribution Fee shall be 100% of such Distribution Fee unless or
until the Fund uses a principal underwriter other than the
Distributor and thereafter the Allocable Portion shall be the portion
of the Distribution Fee attributable to (i) Class B Shares of a Fund
sold by the Distributor ("Commission Shares"), (ii) Class B Shares of
the Fund issued in connection with the exchange of Commission Shares
of another Fund, and (iii) Class B Shares of the Fund issued in
connection with the reinvestment of dividends and capital gains.

         The Distributor's Allocable Portion of the Distribution Fee
and the contingent deferred sales charges arising in respect of Class
B Shares taken into account in computing the Distributor's Allocable
Portion shall be limited under Rule 2830 of the Conduct Rules or
other applicable regulations of the NASD as if the Class B Shares
taken into account in computing the Distributor's Allocable Portion
themselves constituted a separate class of shares of a Fund.

         The services rendered by the Distributor for which the
Distributor is entitled to receive the Distributor's Allocable
Portion of the Distribution Fee shall be deemed to have been
completed at the time of the initial purchase of the Commission
Shares (whether of the Fund or another Fund in the Calvert Group of
Funds) taken into account in computing the Distributor's Allocable
Portion. Notwithstanding anything to the contrary in this Agreement,
the Distributor shall be paid its Allocable Portion of the
Distribution Fee notwithstanding the Distributor's termination as
principal underwriter of the Class B Shares of a Fund, or any
termination of this Agreement other than in connection with a
Complete Termination (as defined in the Distribution Plan) of the
Class B Distribution Plan as in effect on the date of this Agreement.
Except as provided in the preceding sentence, a Fund's obligation to
pay the Distribution Fee to the Distributor shall be absolute and
unconditional and shall not be subject to any dispute, offset,
counterclaim or defense whatsoever, (it being understood that nothing
in this sentence shall be deemed a waiver by a Fund of its right
separately to pursue any claims it may have against the Distributor
and to enforce such claims against any assets (other than its rights
to be paid its Allocable Portion of the Distribution Fee and to be
paid the contingent deferred sales charges) of the Distributor.

         iii. Class C. In consideration of the Distributor's services
as distributor for the Class C Shares of a Fund, each Fund shall pay
to the Distributor the Distribution Fee as set forth in Schedule II
to this Agreement that is payable pursuant to the Fund's Distribution
Plan.

         b.       Service Fee. As additional compensation, for Class
A, Class B and Class C Shares of each Series, applicable Funds shall
pay the Distributor a service fee (as that term is defined by the
National Association of Securities Dealers, Inc. ("NASD")) as set
forth in Schedule III to this Agreement that is payable pursuant to
the Fund's Distribution Plan.

         c.       Front-end Sales Charges. As additional compensation
for the services performed and the expenses assumed by the
Distributor under this Agreement, the Distributor may, in conformity
with the terms and conditions set forth in the then current
Prospectus of each Fund, impose and retain for its own account the
amount of the front-end sales charge, if any, and may reallow a
portion of any front-end sales charge to other broker-dealers, all in
accordance with NASD rules.

         d.       Contingent Deferred Sales Charge. Each Fund will
pay to the Distributor (or its designee or transferee) in addition to
the fees set forth in Section 3 hereof any contingent deferred sales
charge imposed on redemptions of that Fund's Class B and Class C
Shares upon the terms and conditions set forth in the then current
Prospectus of that Fund. Notwithstanding anything to the contrary in
this Agreement, the Distributor shall be paid such contingent
deferred sales charges in respect of Class B Shares taken into
account in computing the Distributor's Allocable Portion of the
Distribution Fee notwithstanding the Distributor's termination as
principal underwriter of the Class B shares of a Fund or any
termination of this Agreement other than in connection with a
Complete Termination of the Class B Distribution Plan as in effect on
the date of this Agreement. Except as provided in the preceding
sentence, a Fund's obligation to remit such contingent deferred sales
charges to the Distributor shall not be subject to any dispute,
offset, counterclaim or defense whatsoever, it being understood that
nothing in this sentence shall be deemed a waiver by a Fund of its
right separately to pursue any claims it may have against the
Distributor and to enforce such claims against any assets (other than
the Distributor's right to be paid its Allocable Portion of the
Distribution Fee and to be paid the contingent deferred sales
charges) of the Distributor. No Fund will waive any contingent
deferred sales charge except under the circumstances set forth in the
Fund's current Prospectus without the consent of the Distributor (or,
if rights to payment have been transferred, the transferee), which
consent shall not be unreasonably withheld.

         4.       Payments to Distributor's Transferees. The
Distributor may transfer the right to payments hereunder (but not its
obligations hereunder) in order to raise funds to cover distribution
expenditures, and any such transfer shall be effective upon written
notice from the Distributor to the Fund. In connection with the
foregoing, the Fund is authorized to pay all or a part of the
Distribution Fee and/or contingent deferred sales charges in respect
of Class B Shares directly to such transferee as directed by the
Distributor.

         5.       Changes in Computation of Fee, etc. As long as the
Class B Distribution Plan is in effect, a Fund shall not change the
manner in which the Class B Distribution Fee is computed (except as
may be required by a change in applicable law or a change in
accounting policy adopted by the Investment Companies Committee of
the AICPA and approved by FASB that results in a determination by a
Fund's independent accountants that any of the sales charges in
respect of such Fund, which are not contingent deferred sales charges
and which are not yet due and payable, must be accounted for by such
Fund as a liability in accordance with GAAP).

         6.       As used in this Agreement, the term "Registration
Statement" shall mean the registration statement most recently filed
by a Fund with the Securities and Exchange Commission and effective
under the 1933 Act, as such Registration Statement is amended by any
amendments thereto at the time in effect, and the term "Prospectus"
shall mean the form of prospectus filed by a Fund as part of the
Registration Statement.

         7.       The Distributor shall print and distribute to
prospective investors Prospectuses, and may print and distribute such
other sales literature, reports, forms, and advertisements in
connection with the sale of the Shares as comply with the applicable
provisions of federal and state law. In connection with such sales
and offers of sale, the Distributor shall give only such information
and make only such statements or representations, and require
broker-dealers with whom it enters into dealer agreements to give
only such information and make only such statements or
representations, as are contained in the Prospectus or in information
furnished in writing to the Distributor by a Fund. The Funds shall
not be responsible in any way for any other information, statements
or representations given or made by the Distributor, other
broker-dealers, or the representatives or agents of the Distributor
or such broker-dealers. Except as specifically permitted under the
Distribution Plan under Rule 12b-1 under the 1940 Act, as provided in
paragraph 3 of this Agreement, the Funds shall bear none of the
expenses of the Distributor in connection with its offer and sale of
the Shares.

         8.       Each Fund agrees at its own expense to register the
Shares with the Securities and Exchange Commission, state and other
regulatory bodies, and to prepare and file from time to time such
Prospectuses, amendments, reports and other documents as may be
necessary to maintain the Registration Statement. Each Fund shall
bear all expenses related to preparing and typesetting its
Prospectus(es) and other materials required by law and such other
expenses, including printing and mailing expenses related to the
Fund's communications with persons who are shareholders of such Fund.

         9.       Each Fund agrees to indemnify, defend and hold the
Distributor, its several officers and directors, and any person who
controls the Distributor within the meaning of Section 15 of the 1933
Act, free and harmless from and against any and all claims, demands,
liabilities and expenses (including the cost of investigating or
defending such claims, demands or liabilities and any counsel fees
incurred in connection therewith) which the Distributor, its officers
or directors, or any such controlling person may incur, under the
1933 Act or under common law or otherwise, arising out of or based
upon any alleged untrue statement of a material fact contained in its
Registration Statement or Prospectus or arising out of or based upon
any alleged omission to state a material fact required to be stated
in either thereof or necessary to make the statements in either
thereof not misleading, provided that in no event shall anything
contained in this Agreement be construed so as to protect the
Distributor against any liability to a Fund or its shareholders to
which the Distributor would otherwise be subject by reason of willful
misfeasance, bad faith, or gross negligence, in the performance of
its duties, or by reason of its reckless disregard of its obligations
and duties under this Agreement.

         10.      The Distributor agrees to indemnify, defend and
hold each Fund, their several officers and directors, and any person
who controls a Fund within the meaning of Section 15 of the 1933 Act,
free and harmless from and against any and all claims, demands,
liabilities and expenses (including the cost of investigating or
defending such claims, demands or liabilities and any counsel fees
incurred in connection therewith) which a Fund, its officers or
directors, or any such controlling person may incur, under the 1933
Act or under common law or otherwise, arising out of or based upon
any alleged untrue statement or a material fact contained in
information furnished in writing by the Distributor to the Funds for
use in the Registration Statement or Prospectus(es) or arising out of
or based upon any alleged omission to state a material fact in
connection with such information required to be stated in the
Registration Statement or Prospectus(es) or necessary to make such
information not misleading.

         11.      Each Fund reserves the right at any time to
withdraw all offerings of the Shares by written notice to the
Distributor at its principal office.

         12.       The Distributor is an independent contractor and
shall be agent for a Fund only in respect to the offer, sale and
redemption of that Fund's Shares.

         13.      The services of the Distributor to a Fund under
this Agreement are not to be deemed exclusive, and the Distributor
shall be free to render similar services or other services to others
so long as its services hereunder are not impaired thereby.

         14.      The Distributor acknowledges that it has received
notice of and accepts the limitations upon the liability of any Fund
organized as a business trust set forth in such Fund's Declaration of
Trust. The Distributor agrees that the obligations of such Funds
hereunder in any case shall be limited to such Funds and to their
assets and that the Distributor shall not seek satisfaction of any
such obligation from the shareholders of such a Fund nor from any
Trustee, officer, employee or agent of such Fund.

         15.      The Funds shall not use the name of the Distributor
in any Prospectus, sales literature or other material relating to the
Funds in any manner not approved prior thereto by the Distributor;
provided, however, that the Distributor shall approve all uses of its
name which merely refer in accurate terms to its appointment
hereunder or which are required by the Securities and Exchange
Commission or a State Securities Commission; and, provided further,
that in no event shall such approval be unreasonably withheld. The
Distributor shall not use the name of any Fund in any material
relating to the Distributor in any manner not approved prior thereto
by the Fund; provided, however that the Funds shall approve all uses
of their names which merely refer in accurate terms to the
appointment of the Distributor hereunder or which are required by the
Securities and Exchange Commission or a State Securities Commission;
and, provided further, that in no event shall such approval be
unreasonably withheld.

         16.      The Distributor shall prepare written reports for
the Board of Trustees/Directors of each Fund on a quarterly basis
showing information concerning services provided and expenses
incurred which are related to this Agreement and such other
information as from time to time shall be reasonably requested by a
Fund's Board of Trustees/Directors.

         17.      As used in this Agreement, the terms "assignment,"
"interested person," and "majority of the outstanding voting
securities" shall have the meaning given to them by Section 2(a) of
the 1940 Act, subject to such exemptions as may be granted by the
Securities and Exchange Commission by any rule, regulation or order;
provided, however that, in order to obtain financing, the Distributor
may assign to a lending institution the payments due to the
Distributor under this Agreement without it constituting an
assignment of the Agreement.

         18.      Subject to the provisions of sections 19 and 20
below, this Agreement will remain in effect for two years from the
date of is execution and from year to year thereafter, provided that
the Distributor does not notify a Fund in writing at least sixty (60)
days prior to the expiration date in any year that it does not wish
continuance of the Agreement as to such Fund for an additional year.

         19.      Termination. As to any particular Fund (or Series
thereof), this Agreement shall automatically terminate in the event
of its assignment and may be terminated at any time without the
payment of any penalty by a Fund or by the Distributor on sixty (60)
days' written notice to the other party. A Fund may effect such
termination by a vote of (i) a majority of the Board of
Trustees/Directors of the Fund, (ii) a majority of the
Trustees/Directors who are not interested persons of the Fund, who
are not parties to this Agreement or interested persons of such
parties, and who have no direct or indirect financial interest in the
operation of the Distribution Plan, in this Agreement or in any
agreement related to such Fund's Distribution Plan (the "Rule 12b-1
Trustees/Directors"), or (iii) a majority of the outstanding voting
securities of the relevant Series.

         20.      This Agreement shall be submitted for renewal to
the Board of Trustees/Directors of each Fund at least annually and
shall continue in effect only so long as specifically approved at
least annually (i) by a majority vote of the Fund's Board of
Trustees/Directors, and (ii) by the vote of the majority of the Rule
12b-1 Trustees/Directors of the Fund, cast in person at a meeting
called for the purpose of voting on such approval.

         IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be executed on the date first above written by their
officers thereunto duly authorized.

                  total  number  of  Shares  which  are  authorized  and
                  issued and  outstanding  and shall have no obligation,
                  when recording the issuance of Shares,  to monitor the
                  issuance of such Shares or to take  cognizance  of any
                  laws  relating  to the  issue or sale of such  Shares,

services  and the  Transfer  Agent may  perform  these  services on each
Fund's behalf.

1.4      The Bank shall  provide  additional  services  on behalf of the
Transfer  Agent  (i.e.,  escheat  services)  that may be agreed  upon in
writing between the Bank and the Transfer Agent.

2.       Fees and Expenses

2.1      For the  performance  by the Bank  pursuant to this  Agreement,
the Transfer Agent agrees to pay the Bank an annual  maintenance fee for
each  Shareholder  account  as  set  out  in the  initial  fee  schedule
attached  hereto.  Such fees and  out-of-pocket  expenses  and  advances
identified  under  Section  2.2 below may be  changed  from time to time
subject to mutual written  agreement  between the Transfer Agent and the
Bank.

2.2      In  addition  to the fee paid  under  Section  2.1  above,  the
Transfer Agent agrees to reimburse the Bank for out-of-pocket  expenses,
including, but not limited to confirmation  production,  postage, forms,
telephone, microfilm,  microfiche,  tabulating proxies, records storage,
or  advances  incurred  by the  Bank  for the  items  set out in the fee
schedule  attached hereto.  In addition,  any other expenses incurred by
the Bank at the request or with the consent of the Transfer Agent,  will
be reimbursed by the Transfer Agent.

2.3      The  Transfer  Agent  agrees  to pay all fees and  reimbursable
expenses  within  fifteen days  following the receipt of the  respective
billing notice. Postage for mailing of dividends,  proxies, Fund reports
and other mailings to all shareholder  accounts shall be advanced to the
Bank by the Transfer  Agent at least seven (7) days prior to the mailing
date of such materials.

3.       Wire Transfer Operating  Guidelines/Articles 4A of the Uniform 
Commercial Code

3.1      The  Bank is  authorized  to  promptly  debit  the  appropriate
Transfer  Agent  account(s)  upon  the  receipt  of a  payment  order in
compliance   with  the  selected   security   procedure  (the  "Security
Procedure")  chosen for funds  transfer  and in the amount of money that
the  Bank has been  instructed  to  transfer.  The  Bank  shall  execute
payment  orders in compliance  with the Security  Procedure and with the
Transfer  Agent's  instructions on the execution date provided that such
payment order is received by the customary  deadline for processing such
a request,  unless the payment order specifies a later time. All payment
orders and communications  received after this time frame will be deemed
to have been received the next business day.

3.2      The Transfer Agent  acknowledges that the Security Procedure it
has designated on the Transfer Agent  Selection Form was selected by the
Transfer  Agent  from  security  procedures  offered  by the  Bank.  The
Transfer  Agent  shall  restrict  access  to  confidential   information
relating  to  the   Security   Procedure   to   authorized   persons  as
communicated to the Bank in writing.  The Transfer Agent must notify the
Bank  immediately if it has reason to believe  unauthorized  persons may
have  obtained  access  to  such  information  or of any  change  in the
Transfer  Agent's  authorized  personnel.  The  Bank  shall  verify  the
authenticity  of  all  such  instructions   according  to  the  Security
Procedure.

3.3      The Bank shall  process all payment  orders on the basis of the
account  number  contained  in the  payment  order.  In the  event  of a
discrepancy  between any name  indicated  on the  payment  order and the
account number, the account number shall take precedence and govern.

3.4      When a Transfer Agent initiates or receives  Automated Clearing
House ("ACH") credit and debit entries  pursuant to these guidelines and
the rules of the National  Automated  Clearing House Association and the
New  England  Clearing  House  Association,  the  Bank  will  act  as an
Originating    Depository   Financial   Institution   and/or   receiving
Depository  Financial  Institution,  as the case may be, with respect to
such  entries.  Credits  given by the Bank with respect to an ACH credit
entry are provisional  until the Bank receives final settlement for such
entry from the Federal  Reserve  Bank. If the Bank does not receive such
final settlement,  the Transfer Agent agrees that the Bank shall receive
a refund of the amount  credited  to the  Transfer  Agent in  connection
with such entry,  and the party making payment to the Transfer Agent via
such entry shall not be deemed to have paid the amount of the entry.

3.5      The Bank  reserves the right to decline to process or delay the
processing  of a payment  order which (a) is in excess of the  collected
balance in the  account to be charged at the time of the Bank's  receipt
of such payment order,  or (b) if the Bank, in good faith,  is unable to
satisfy itself that the transaction has been properly authorized.

3.6      The Bank shall use reasonable  efforts to act on all authorized
requests to cancel or amend  payment  orders  received  if requests  are
received in a timely manner  affording the Bank  reasonable  opportunity
to act.  However,  the Bank  assumes no  liability  if the  request  for
amendment or cancellation cannot be satisfied.

3.7      The Bank shall assume no  responsibility  for failure to detect
any  erroneous  payment  order  provided that the Bank complies with the
payment  order  instructions  as received and the Bank complies with the
Security  Procedure.  The  Security  Procedure  is  established  for the
purpose of authenticating  payment orders only and not for the detection
of errors in payment orders.

3.8      The Bank shall assume no responsibility  for lost interest with
respect to the retransfer  Agentable amount of any unauthorized  payment
order  unless the Bank is notified  of the  unauthorized  payment  order
within thirty (30) days of  notification  by the Bank of the  acceptance
of such  payment  order.  In no event  (including  failure  to execute a
payment  order)  shall  the Bank be  liable  for  special,  indirect  or
consequential  damages,  even  if  advised  of the  possibility  of such
damages.

3.9      Confirmation  of  Bank's  execution  of  payment  orders  shall
ordinarily be provided  within 24 hours notice of which may be delivered
through the Bank's proprietary  information  systems, or by facsimile or
call-back.  Client must report any  objections  to the  execution  of an
order within 30 days.

The Transfer Agent acknowledges that the data bases,  computer programs,
screen  formats,  report formats,  interactive  design  techniques,  and
other  information  furnished  to the  Transfer  Agent  by the  Bank are
provided  solely in  connection  with the services  rendered  under this
Agreement  and  constitute  copyrighted  trade  secrets  or  proprietary
information of substantial value to the Bank. Such databases,  programs,
formats,  designs,  techniques and other  information  are  collectively
referred  to below as  "Proprietary  Information".  The  Transfer  Agent
agrees that it shall treat all  Proprietary  Information  as proprietary
to  the  Bank  and  further   agrees  that  it  shall  not  divulge  any
Proprietary   Information  to  any  person  or  organization  except  as
expressly permitted hereunder.  The Transfer Agent agrees for itself and
its employees and Agents:

         (a)      to use such  programs and  databases (i) solely on the
         Transfer  Agent's  computers,  or (ii) solely from equipment at
         the  locations  agreed to between  the  Transfer  Agent and the
         Bank and (iii) in accordance  with the Bank's  applicable  user
         documentation;

         (b)      to  refrain  from  copying or  duplicating  in any way
         (other than in the normal  course of  performing  processing on
         the Transfer  Agent's  computers)  any part of any  Proprietary
         Information;

         (c)      to refrain from obtaining  unauthorized  access to any
         programs,  data or other  information not owned by the Transfer
         Agent, and if such access is accidentally  obtained, to respect
         and safeguard the same Proprietary Information;

         (d)      to  refrain  from  causing  or  allowing   proprietary
         information   transmitted  from  the  Bank's  computer  to  the
         Transfer  Agent's  terminal  to be  retransmitted  to any other
         computer   terminal  or  other   device   except  as  expressly
         permitted by the Bank,  such  permission not to be unreasonably
         withheld;

         (e)      that the  Transfer  Agent  shall have  access  only to
         those   authorized   transactions  as  agreed  to  between  the
         Transfer Agent and the Bank; and

         (f)      to honor reasonable  written requests made by the Bank
         to  protect  at the  Bank's  expense  the rights of the Bank in
         Proprietary Information at common law and under
         applicable statutes.

Each party  shall take  reasonable  efforts to advise its  employees  of
their obligations pursuant to this Section 4.

5.       Indemnification

5.1      Except as provided in Section 6, herein,  the Bank shall not be
responsible  for, and the Transfer  Agent shall  indemnify  and hold the
Bank  harmless  from and against,  any and all losses,  damages,  costs,
charges,  counsel fees, payments,  expenses and liability arising out of
or attributable to:

         (a)      all   actions   of   the   Bank   or  its   agent   or
         subcontractors   required   to  be  taken   pursuant   to  this
         Agreement,  provided  that such actions are taken in good faith
         and without negligence or willful misconduct;

         (b)      the Transfer  Agent's  lack of good faith,  negligence
         or willful misconduct;

         (c)      the  reliance  on or use by the Bank or its  agents or
         subcontractors of information,  records,  documents or services
         which   (i)  are   given   to  the  Bank  or  its   agents   or
         subcontractors,  and (ii) have  been  prepared,  maintained  or
         performed by the Transfer  Agent or any other person or firm on
         behalf of the Transfer  Agent  including but not limited to any
         previous transfer agent or registrar excluding the Bank;

         (d)      the  reliance  on, or the  carrying out by the Bank or
         its agents or  subcontractors  of any  instructions or requests
         of the Transfer Agent; and

         (e)      the  offer  or  sale of  Shares  in  violation  of any
         requirement  under the federal  securities  laws or regulations

         Shares be  registered in such state or in violation of any stop

         in such state.

5.2      At any time the Bank may apply to any  officer of the  Transfer
Agent for instructions,  and may consult with legal counsel with respect
to any matter  arising in  connection  with the services to be performed
by the  Bank  under  this  Agreement,  and the Bank  and its  Agents  or
subcontractors  shall not be  liable  and  shall be  indemnified  by the
Transfer  Agent for any action  taken or omitted by it in reliance  upon
such instructions or upon the opinion of such counsel.

The  Bank,  its  agents  and  subcontractors   shall  be  protected  and
indemnified  in acting  upon any paper or  document  furnished  by or on
behalf of the Transfer Agent,  reasonably believed by the Batik as being
in good order and to have been  signed by the proper  person or persons,
or  upon  any  instruction,  information,  data,  records  or  documents
provided the Bank or its Agents or  subcontractors  by machine  readable
input,  telex,  CRT data entry or other similar means  authorized by the
Transfer  Agent,  and shall not be held to have  notice of any change of
authority of any person,  until receipt of written  notice  thereof from
the Transfer Agent. The Bank, its agents and  subcontractors  shall also
be protected and  indemnified in recognizing  stock  certificates  which
are  reasonably   believed  to  bear  the  proper  manual  or  facsimile
signatures  of the  officers  of the  Transfer  Agent,  and  the  proper
countersignature  of the Transfer Agent or any former  transfer agent or
former registrar, or of a co-transfer agent or co-registrar.

Section  5 shall  apply,  upon the  assertion  of a claim  for which the
Transfer  Agent may be required to  indemnify  the Bank,  the Bank shall
promptly  notify the Transfer  Agent of such  assertion,  and shall keep
the Transfer Agent advised with respect to all  developments  concerning
such claim.  The  Transfer  Agent  shall have the option to  participate
with the Bank in the  defense  of such claim or to defend  against  said
claim in its own name or in the name of the Bank.  The Bank  shall in no
case confess any claim or make any  compromise  in any case in which the
Transfer  Agent may be  required to  indemnify  the Bank except with the
Transfer Agent's prior written consent.

6.       Standard of Care

use its best efforts within  reasonable limits to insure the accuracy of
all   services   performed   under  this   Agreement,   but  assumes  no
responsibility  and shall not be liable for loss or damage due to errors
unless said errors are caused by its  negligence,  bad faith, or willful
misconduct or that of its employees.

        AMENDMENT TO SUB-TRANSFER AGENCY AND SERVICE AGREEMENT
                                between
                   CALVERT SHAREHOLDER SERVICES, INC.
                                  and
                  STATE STREET BANK AND TRUST COMPANY


General Background:

Calvert Shareholder Services, Inc. ("CSSI"), and State Street Bank and
Trust Company ("State Street") entered into a sub-transfer agency and
service agreement ("Agreement") dated August 15, 1996.

For accounting reasons, CSSI desires to amend the Agreement by
assigning the contract for the transfer agent functions (except for
shareholder servicing) to each Calvert Group Fund.  CSSI will continue
to be responsible for the shareholder servicing and for any
responsibilities currently shown as Transfer Agent responsibilities in
Fund Service Responsibilities attachment to the Agreement.

The Agreement must be assigned to the Calvert Group Funds for
accounting purposes.

CSSI and State Street must each consent to this assignment.

Changes caused by this assignment:

The current subtransfer agent, National Financial Data Services, Inc.
("NFDS"), will bill each Calvert Group Fund, rather than CSSI, and each
Calvert Group Fund shall pay State Street or its billing agent, NFDS,
all fees and expenses incurred under the Agreement on behalf of each
respective Calvert Group Fund.

NFDS will be shown in each Calvert Group Fund prospectus and statement
of additional information as the Transfer Agent, while CSSI will be
shown as the shareholder servicing agent.

State Street (NFDS) will continue to perform those functions shown in
the Agreement as Bank responsibilities.

CSSI will continue to perform the Transfer Agent responsibilities, as
shown in the Fund Service Responsibilities attachment to the Agreement.

The Assignment:

This Amendment, dated as of the first day of January, 1998, by and
among CSSI and State Street:

Now, Therefore, CSSI and State Street each hereby agree that the
Agreement will be between each Calvert Group Fund and State Street, and
each hereby agrees that the Agreement is so assigned.

In Witness Whereof, CSSI and State Street have caused this Amendment to
be executed by their duly authorized officers, effective as of January
1, 1998.

                         SERVICING AGREEMENT

         This  Agency  Agreement,  effective  January 1, 1998,  by and
between Calvert  Shareholder  Services,  Inc., a Delaware  corporation
having  its  principal   place  of  business  in  Bethesda,   Maryland
("CSS"),  and  registered  investment  companies  sponsored by Calvert
Group,  Ltd.  and  its  subsidiaries  and  set  forth  on  Schedule  A
("Calvert  Group  Funds" or  "Funds").  The Funds have  entered into a
transfer  agency and service  agreement with the State Street Bank and
Trust  of  Boston,   Massachusetts  ("State  Street")  ("State  Street
Agreement").

         1.       Appointments.  The  Funds  hereby  appoints  CSS  as
servicing  agent,  agent  and  shareholder  servicing  agent  for  the
Funds,  and CSS hereby accepts such  appointment and agrees to perform
those duties in  accordance  with the terms and  conditions  set forth
in this Agreement.

         2.       Documentation.  The Funds will  furnish CSS with all
documents,  certificates,  contracts,  forms,  and opinions which CSS,
in its  discretion,  deems necessary or appropriate in connection with
the proper performance of its duties under this Agreement.

         3.       Services to be  Performed.  CSS will be  responsible
for  telephone  servicing  functions,   system  interface  with  State
Street and oversight of State  Street's  administering  and performing
their duties  pursuant to the State Street  Agreement.  The details of
the  operating  standards  and  procedures  to  be  followed  will  be
determined from time to time by agreement between CSS and the Funds.

         4.       Recordkeeping  and  Other  Information.   CSS  will,
commencing  on the  effective  date of this  Agreement,  to the extent
necessary  create and maintain all  necessary  shareholder  accounting
records  in   accordance   with  all   applicable   laws,   rules  and
regulations,   including  but  not  limited  to  records  required  by
Section 31(a) of the  Investment  Company Act of 1940, as amended (the
"1940 Act"), and the rules  thereunder,  as amended from time to time.
All  such  records  will  be the  property  of the  Fund  and  will be
available for inspection and use by such Fund.

         5.       Audit,  Inspection  and  Visitation.  CSS will  make
available  during  regular  business  hours all records and other data
created and  maintained  pursuant  to this  Agreement  for  reasonable
audit and  inspection  by the SEC, a Fund or any person  retained by a
Fund.

         6.       Compensation.  The Funds  will  compensate  CSS on a
monthly basis for the services  performed  pursuant to this Agreement,
at the rate of  compensation  set forth in  Schedule  A. Out of pocket
expenses  incurred  by CSS  and not  included  in  Schedule  A will be
reimbursed  to CSS by the Fund,  as  appropriate;  such  expenses  may
include,  but are not  limited  to,  special  forms  and  postage  for
mailing  the  forms.  These  charges  will be  payable  in  full  upon
receipt of a billing  invoice.  In lieu of  reimbursing  CSS for these
expenses, any Fund may, in its discretion, directly pay the expenses.

         7.       Use of  Names.  No Fund will not use the name of CSS
in any  prospectus,  sales  literature or other  material  relating to
the  Fund in any  manner  without  prior  approval  by CSS;  provided,
however,  that CSS will  approve  all  uses of its  name  that  merely
refer in accurate  terms to its  appointment  under this  Agreement or
that are required by the SEC or a State  Securities  Commission;  and,
provided,  further,  that in no event will  approval  be  unreasonably
withheld.

         8.       Security.  CSS  represents and warrants that, to the
best of its  knowledge,  the various  procedures  and systems that CSS
proposes  to  implement  with  regard  to  safeguarding  from  loss or
damage  attributable  to fire,  theft or any  other  cause  (including
provision for  twenty-four  hour a day restricted  access) the Fund's,
records   and  other  data  and  CSS's   records,   data,   equipment,
facilities  and  other  property  used  in  the   performance  of  its
obligations  under  this  Agreement  are  adequate  and  that  it will
implement  them in the  manner  proposed  and make such  changes  from
time  to  time  as  in  its  judgment  are  required  for  the  secure
performance of obligations under this Agreement.

         9.       Limitation  of Liability.  Each Fund will  indemnify
and  hold  CSS   harmless   against  any  losses,   claims,   damages,
liabilities  or  expenses  (including   reasonable  counsel  fees  and
expenses)  resulting  from any claim,  demand,  action or suit brought
by any person  (including a  shareholder  naming such Fund as a party)
other  than such Fund not  resulting  from  CSS's bad  faith,  willful
misfeasance,  reckless  disregard of its  obligations  and duties,  or
negligence  arising out of, or in connection with,  CSS's  performance
of its obligations under this Agreement.

         To the  extent  CSS has not  acted  with bad  faith,  willful
misfeasance,  reckless  disregard of its  obligations  and duties,  or
gross  negligence,   each  Fund  will  also  indemnify  and  hold  CSS
harmless  against  any  losses,   claims,   damages,   liabilities  or
expenses  (including  reasonable counsel fees and expenses)  resulting
from any claim,  demand,  action or suit resulting from the negligence
of such  Fund,  or  CSS's  acting  upon  any  instructions  reasonably
believed  by it to have been  executed or  communicated  by any person
duly  authorized  by such  Fund,  or as a result  of CSS's  acting  in
reliance  upon  advice  reasonably  believed by CSS to have been given
by counsel  for the Fund,  or as a result of CSS's  acting in reliance
upon any  instrument  reasonably  believed by it to have been  genuine
and signed, countersigned or executed by the proper person.

         CSS's   liability  for  any  and  all  claims  of  any  kind,
including  negligence,   for  any  loss  or  damage  arising  out  of,
connected  with,  or  resulting  from  this  Agreement,  or  from  the
performance  or  breach  thereof,  or from  the  design,  development,
lease,  repair,  maintenance,  operation  or  use of  data  processing
systems and the  maintenance of a Funds'  shareholder  account records
as provided for by this  Agreement  will in the  aggregate  not exceed
the  total  of  CSS's  compensation   hereunder  for  the  six  months
immediately  preceding the discovery of the circumstances  giving rise
to such liability.

         In no event  will CSS be liable  for  indirect,  special,  or
consequential   damages   (even  if  CSS  has  been   advised  of  the
possibility  of such  damages)  arising from the  obligations  assumed
hereunder and the services  provided for by this Agreement,  including
but not  limited  to  lost  profits,  loss  of use of the  shareholder
accounting  system,  cost of capital,  cost of substitute  facilities,
programs or services,  downtime costs,  or claims of shareholders  for
such damage.

         10.      Limitation   of   Liability   of   the   Fund.   CSS
acknowledges  that it accepts the  limitations  upon the  liability of
the  Funds.  CSS  agrees  that  each  Fund's  obligations  under  this
Agreement  in any case will be  limited to such Fund and to its assets
and that CSS will not seek  satisfaction  of any  obligation  from the
shareholders  of the Fund nor from  any  director,  trustee,  officer,
employee or agent of such Fund.

         11.      Force Majeure.  CSS will not be liable for delays or
errors  occurring  by  reason of  circumstances  beyond  its  control,
including  but not  limited  to acts of civil or  military  authority,
national emergencies,  work stoppages, fire, flood, catastrophe,  acts
of God,  insurrection,  war,  riot,  or  failure of  communication  or
power  supply.  In  the  event  of  equipment  breakdowns  beyond  its
control,   CSS  will  take  reasonable   steps  to  minimize   service
interruptions but will have no liability with respect thereto.

         12.      Amendments.   CSS  and  each  Fund  will   regularly
consult  with  each  other   regarding   CSS's   performance   of  its
obligations   under   this   Agreement.   Any   change   in  a  Fund's
registration   statements   under  the  Securities  Act  of  1933,  as
amended,  or the  1940  Act  or in the  forms  relating  to any  plan,
program  or service  offered by the  current  prospectus  which  would
require a change in CSS's  obligations  under this  Agreement  will be
subject to CSS's approval,  which will not be  unreasonably  withheld.
Neither  this  Agreement  nor any of its  provisions  may be  changed,
waived,   discharged,  or  terminated  orally,  but  only  by  written
instrument  which will make specific  reference to this  Agreement and
which will be signed by the party  against which  enforcement  of such
change, waiver, discharge or termination is sought.

         13.      Termination.  This Agreement will continue in effect
until  January 1, 1999,  and  thereafter  as the parties may  mutually
agree;  provided,  however,  that this  Agreement may be terminated at
any time by either  party  upon at least  sixty  days'  prior  written
notice to the other party;  and provided  further that this  Agreement
may be  terminated  immediately  at any time for  cause  either by any
Fund or CSS in the event that such  cause  remains  unremedied  for no
less than ninety days after receipt of written  specification  of such
cause.   Any  such   termination   will  not  affect  the  rights  and
obligations  of the parties under  Paragraphs 9 and 10 hereof.  In the
event that a Fund  designates a successor to any of CSS's  obligations
hereunder,  CSS will,  at the  expense  and  direction  of such  Fund,
transfer  to such  successor  all  relevant  books,  records and other
data  of  such  Fund  established  or  maintained  by CSS  under  this
Agreement.

         15.      Miscellaneous.  Each party  agrees to  perform  such
further acts and execute such  further  documents as are  necessary to
effectuate  the purposes of this  Agreement.  This  Agreement  will be
construed  and  enforced in  accordance  with and governed by the laws
of  the  State  of  Maryland.  The  captions  in  this  Agreement  are
included for  convenience  only and in no way define or delimit any of
the  provisions  hereof or  otherwise  affect  their  construction  or
effect.

         IN WITNESS  WHEREOF,  the  parties  have duly  executed  this
Agreement as of the day and year first above written.
