HARTFORD GROWTH AND INCOME HLS FUND                                            3
- --------------------------------------------------------------------------------
 
            INTRODUCTION TO THE HARTFORD GROWTH AND INCOME HLS FUND
 
    The Fund is a diversified series of Hartford Series Fund, Inc. (the
"Company"), an open-end management investment company which was organized as a
Maryland corporation on January 15, 1998. The Fund commenced operations on
           , 1998. The Fund is made available to serve as the underlying
investment vehicle for certain variable annuity and variable life insurance
separate accounts of The Hartford Life Insurance Companies.
 
    The Fund offers Class IA and Class IB shares. Only Class IA shares of the
Fund are offered by this Prospectus. Each Class incurs different expenses which
will affect performance. Class IB shares are offered pursuant to another
prospectus and are subject to the same expenses as the Class IA shares, but
unlike the Class IA shares they are subject to distribution fees imposed
pursuant to a distribution plan ("Distribution Plan") adopted under Rule 12b-1
of the Investment Company Act of 1940 (the "1940 Act"). Inquiries regarding
Class IB shares should be addressed to Hartford Growth and Income HLS Fund, c/o

    HL Investment Advisors, Inc. ("HL Advisors") is the investment manager to
the Fund. In addition, under HL Advisors' general management, Wellington
Management Company, LLP ("Wellington Management") serves as sub-adviser to the
Fund.
 
   
    HL Advisors was incorporated in Connecticut in 1981 and is a majority-owned
indirect subsidiary of The Hartford Financial Services Group, Inc. ("The
Hartford"), a Connecticut insurance holding company with over $100 billion in
assets. Wellington Management, a Massachusetts limited liability partnership, is
a professional investment counseling firm that provides services to investment
companies, employee benefit plans, endowments, foundations and other
institutions and individuals. Wellington Management and its predecessor
organizations have provided investment advisory services since 1928. As of
December 31, 1997, HL Advisors had investment management authority with respect
to approximately $24 billion of assets for various clients. As of the same date,
Wellington Management had investment management authority with respect to
approximately $175 billion of assets for various clients.
    
 
                            INVESTMENT OBJECTIVE AND
                               STYLE OF THE FUND
 
    The Fund is subject to certain fundamental investment restrictions that are
enumerated in detail in the SAI and may not be changed without shareholder
approval. All other investment policies (including the Fund's investment
objective) are non-fundamental and may be changed by the Board of Directors
without shareholder approval. Stated below is the investment objective and
investment style for the Fund. For a description of the Fund's investment
policies and risk factors, see "Common Investment Policies and Risk Factors."
 
    INVESTMENT OBJECTIVE.
 
   
    The Growth and Income HLS Fund seeks growth of capital and current income by
investing primarily in equity securities with earnings growth potential and
steady or rising dividends.
    
 
    INVESTMENT STYLE.
 
    The Growth and Income HLS Fund invests in a diversified portfolio of
primarily equity securities that typically have steady or rising dividends and
whose prospects for capital appreciation are considered favorable by Wellington
Management. Wellington Management uses fundamental analysis to evaluate a
security for purchase or sale by the Fund. Fundamental analysis involves the
assessment of a company through such factors as its business environment,
management, balance sheet, income statement, anticipated earnings, revenues,
dividends, and other related measures of value. Wellington Management then uses
proprietary quantitative techniques to affirm its fundamental evaluation of a
security. The quantitative techniques evaluate a security using valuation
analysis, which includes use of a dividend discount model and cash flow
analysis, combined with momentum analysis, which includes an assessment of a
company's earnings momentum and stock price momentum. The quantitative
techniques look to affirm the fundamental evaluation by identifying those
securities that are attractive from the fundamental perspective and are also
both inexpensive based on the quantitative valuation factors and timely
according to the quantitative momentum factors. The Fund's portfolio will be
broadly diversified by industry and company. Up to 20% of the Fund's total
assets may be invested in securities of non-U.S. companies.
 
                           COMMON INVESTMENT POLICIES
                                AND RISK FACTORS
 
                          MONEY MARKET INSTRUMENTS AND
                        TEMPORARY INVESTMENT STRATEGIES
 
   
    The Fund may hold cash and invest in high quality money market instruments
under appropriate circumstances as determined by Wellington Management. The Fund
may invest up to 100% of its assets in cash or money market instruments only for
temporary defensive purposes.
    
 
    Money market instruments include: (1) banker's acceptances; (2) obligations
of governments (whether U.S.
<PAGE>

- --------------------------------------------------------------------------------
 
or non-U.S.) and their agencies and instrumentalities; (3) short-term corporate
obligations, including commercial paper, notes, and bonds; (4) other short-term
debt obligations; (5) obligations of U.S. banks, non-U.S. branches of U.S. banks
(Eurodollars), U.S. branches and agencies of non-U.S. banks (Yankee dollars),
and non-U.S. branches of non-U.S. banks; (6) asset-backed securities; and (7)
repurchase agreements.
 
                             REPURCHASE AGREEMENTS
 
    The Fund is permitted to enter into fully collateralized repurchase
agreements. A repurchase agreement is an agreement by which the seller of a
security agrees to repurchase the security sold at a mutually agreed upon time
and price. It may also be viewed as the loan of money by the Fund to the seller.
The resale price would be in excess of the purchase price, reflecting an agreed
upon market interest rate. Delays or losses could result if the other party to
the agreement defaults or becomes insolvent. The Fund's Board of Directors has
established standards for evaluation of the creditworthiness of the banks and
securities dealers with which the Fund may engage in repurchase agreements and
monitors on a quarterly basis Wellington Management's compliance with such
standards.
 
                         REVERSE REPURCHASE AGREEMENTS
 
    The Fund may also enter into reverse repurchase agreements. Reverse
repurchase agreements involve sales by the Fund of portfolio assets concurrently
with an agreement by the Fund to repurchase the same assets at a later date at a
fixed price. Reverse repurchase agreements carry the risk that the market value
of the securities which the Fund is obligated to repurchase may decline below
the repurchase price. A reverse repurchase agreement is viewed as a
collateralized borrowing by the Fund. Borrowing magnifies the potential for gain
or loss on the portfolio securities of the Fund and, therefore, increases the
possibility of fluctuation in the Fund's net asset value. The Fund will
establish a segregated account with the Fund's custodian bank in which the Fund
will maintain liquid assets equal in value to the Fund's obligations in respect
of reverse repurchase agreements. As a non-fundamental policy, the Fund will not
enter into reverse repurchase transactions if the combination of all borrowings
from banks and the value of all reverse repurchase agreements for the Fund
equals more than 33 1/3% of the value of the Fund's total assets.
 
                                DEBT SECURITIES
 
    The Fund is permitted to invest in debt securities including: (1) securities
issued or guaranteed as to principal or interest by the U.S. Government, its
agencies or instrumentalities; (2) debt securities issued or guaranteed by U.S.
corporations or other issuers (including foreign governments or corporations);
and (3) securities issued or guaranteed as to principal or interest by a
sovereign government or one of its agencies or political subdivisions,
supranational entities such as development banks, non-U.S. corporations, banks
or bank holding companies, or other non-U.S. issuers.
 
                        INVESTMENT GRADE DEBT SECURITIES
 
    The Fund is permitted to invest in debt securities rated within the four
highest rating categories (i.e., Aaa, Aa, A or Baa by Moody's or AAA, AA, A or
BBB by S&P), or, if unrated, securities of comparable quality as determined by
Wellington Management. These securities are generally referred to as "investment
grade securities." Each rating category has within it different gradations or
sub-categories. If the Fund is authorized to invest in a certain rating
category, the Fund is also permitted to invest in any of the sub-categories or
gradations within that rating category. If a security is downgraded to a rating
category which does not qualify for investment, Wellington Management will use
its discretion on whether to hold or sell based upon its opinion on the best
method to maximize value for shareholders over the long term. Debt securities
carrying the fourth highest rating (i.e., "Baa" by Moody's and "BBB" by S&P),
and unrated securities of comparable quality (as determined by Wellington
Management) are viewed as having adequate capacity for payment of principal and
interest, but do involve a higher degree of risk than that associated with
investments in debt securities in the higher rating categories.
 
                      HIGH YIELD-HIGH RISK DEBT SECURITIES
 
    The Fund may invest up to 5% of its assets in high yield debt securities
(i.e., rated as low as "C" by Moody's or S&P, and unrated securities of
comparable quality as determined by Wellington Management). Securities rated
below investment grade are commonly referred to as "high yield-high risk
securities" or "junk bonds". Each rating category has within it different
gradations or sub-categories. If the Fund is authorized to invest in a certain
rating category, the Fund is also permitted to invest in any of the
sub-categories or gradations within that rating category. If a security is
downgraded to a rating category which does not qualify for investment,
Wellington Management will use its discretion on whether to hold or sell based
upon its opinion on the best method to maximize value for shareholders over the
long term. Securities in the rating categories below "Baa" as determined by
Moody's and "BBB" as determined by S&P are considered to be of poor standing and
predominantly speculative. The rating services' descriptions of securities are
set forth in Appendix A. High yield-high risk debt securities are considered
speculative with respect to the issuer's capacity to pay interest and repay
principal in accordance with the terms of the obligations. Accordingly, it is
possible that these types of factors could, in certain instances, reduce

the value of securities held by the Fund with a commensurate effect on the value
of the Fund's shares.
 
                               EQUITY SECURITIES
 
    The Fund may invest in equity securities including common stocks, preferred
stocks, convertible preferred stock and rights to acquire such securities. In
addition, the Fund may invest in securities such as bonds, debentures and
corporate notes which are convertible into common stock at the option of the
holder.
 
                        SMALL CAPITALIZATION SECURITIES
 
    The Fund may invest in equity securities (including securities issued in
initial public offerings) of companies which have less than $2 billion in market
capitalization ("Small Capitalization Securities"). Because the issuers of Small
Capitalization Securities tend to be smaller or less well-established companies,
they may have limited product lines, market share or financial resources and may
have less historical data with respect to operations and management. As a
result, Small Capitalization Securities are often less marketable and experience
a higher level of price volatility than securities of larger or more
well-established companies. In addition, companies whose securities are offered
in initial public offerings may be more dependent on a limited number of key
employees. Because securities issued in initial public offerings are being
offered to the public for the first time, the market for such securities may be
inefficient and less liquid.
 
                              NON-U.S. SECURITIES
 
    The Fund is permitted to invest up to 20% of its assets in non-U.S.
securities. The Fund may invest in American Depositary Receipts ("ADRs") and
Global Depositary Receipts ("GDRs"). ADRs are certificates issued by a U.S. bank
or trust company and represent the right to receive non-U.S. securities. ADRs
are traded on a U.S. securities exchange, or in an over-the-counter market, and
are denominated in U.S. dollars. GDRs are certificates issued globally and
evidence a similar ownership arrangement. GDRs are traded on non-U.S. securities
exchanges and are denominated in non-U.S. currencies. The value of an ADR or a
GDR will fluctuate with the value of the underlying security, will reflect any
changes in exchange rates and otherwise will involve risks associated with
investing in non-U.S. securities.
 
    When selecting non-U.S. securities Wellington Management will evaluate the
economic and political climate and the principal securities markets of the
country in which the company is located. Investing in non-U.S. securities
involves considerations and potential risks not typically associated with
investing in securities issued by U.S. companies. Less information may be
available about non-U.S. companies than about U.S. companies and non-U.S.
companies generally are not subject to uniform accounting, auditing and
financial reporting standards or to other regulatory practices and requirements
comparable to those applicable to U.S. companies. The values of non-U.S.
securities are affected by changes in currency rates or exchange control
regulations, restrictions or prohibitions on the repatriation of non-U.S.
currencies, application of non-U.S. tax laws, including withholding taxes,
changes in governmental administration or economic or monetary policy (in the
U.S. or outside the U.S.) or changed circumstances in dealings between nations.
Costs are also incurred in connection with conversions between various
currencies. The Fund may invest up to 25% of its assets in companies located in
emerging countries. Compared to the United States and other developed countries,
developing countries may have relatively unstable governments, economies based
on only a few industries, and securities markets that are less liquid and trade
a small number of securities. Prices on these exchanges tend to be volatile and,
in the past, securities in these countries have offered greater potential for
gain (as well as loss) than securities of companies located in developed
countries. See the SAI for additional risk disclosure concerning non-U.S.
securities.
 
                             CURRENCY TRANSACTIONS
 
    The Fund may engage in currency transactions to hedge the value of portfolio
securities denominated in particular currencies against fluctuations in relative
value. Currency transactions include forward currency contracts, currency swaps,
exchange-listed and over-the-counter ("OTC") currency futures contracts and
options thereon and exchange listed and OTC options on currencies.
 
    Forward currency contracts involve a privately negotiated 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. Currency swaps are agreements to exchange
cash flows based on the notional difference between or among two or more
currencies. See "Swap Agreements."
 
    The use of currency transactions to protect the value of the Fund's assets
against a decline in the value of a currency does not eliminate potential losses
arising from fluctuations in the value of the Fund's underlying securities.
Further, the Fund may enter into currency transactions only with counterparties
that Wellington Management deems to be creditworthy.
 
    The Fund may also enter into options and futures contracts relative to
foreign currency to hedge against fluctuations in foreign currency rates. See
"Options and Futures Contracts" for a discussion of risk factors relating to
foreign currency transactions including related options and futures contracts.

- --------------------------------------------------------------------------------
 
                         OPTIONS AND FUTURES CONTRACTS
 
    The Fund may employ certain hedging, income enhancement and risk management
techniques involving options and futures contracts, though such techniques may
also result in losses to the Fund. The Fund may write covered call options or
purchase put and call options on individual securities, write covered put and
call options and purchase put and call options on foreign currencies, aggregates
of equity and debt securities, indices of prices of equity and debt securities
and other financial indices, and enter into futures contracts and options
thereon for the purchase or sale of aggregates of equity and debt securities,
indices of equity and debt securities and other financial indices.
 
    The Fund may write covered options only. "Covered" means that, so long as
the Fund is obligated as the writer of an option, it will own either the
underlying securities or currency or an option to purchase or sell the same
underlying securities or currency having an expiration date not earlier than the
expiration date of the covered option and an exercise price equal to or less
than the exercise price of the covered option, or will establish or maintain
with its custodian for the term of the option a "segregated account" consisting
of cash, U.S. Government securities or other liquid, high grade debt obligations
having a value equal to the fluctuating market value of the optioned securities
or currencies. The Fund receives a premium from writing a call or put option,
which increases the Fund's return if the option expires unexercised or is closed
out at a net profit.
 
    To hedge against fluctuations in currency exchange rates, the Fund may
purchase or sell foreign currency futures contracts, and write put and call
options and purchase put and call options on such futures contracts. To the
extent that the Fund enters into futures contracts, options on futures contracts
and options on foreign currencies that are traded on an exchange regulated by
the Commodities Futures Trading Commission ("CFTC"), in each case that are not
for BONA FIDE hedging purposes (as defined by the CFTC), the aggregate initial
margin and premiums required to establish those non-hedging positions may not
exceed 5% of the liquidation value of the Fund's portfolio, after taking into
account the unrealized profits and unrealized losses on any such contracts the
Fund has entered into.
 
    The Fund's use of options, futures and options thereon and forward currency
contracts (as described under "Currency Transactions") would involve certain
investment risks and transaction costs to which it might not be subject were
such strategies not employed. Such risks include: (1) dependence on the ability
of Wellington Management to predict movements in the prices of individual
securities, fluctuations in the general securities markets or market sections
and movements in interest rates and currency markets; (2) imperfect correlation
between movements in the price of the securities or currencies hedged or used
for cover; (3) the fact that skills and techniques needed to trade options,
futures contracts and options thereon or to use forward currency contracts are
different from those needed to select the securities in which the Fund invests;
(4) lack of assurance that a liquid secondary market will exist for any
particular option, futures contract, option thereon or forward contract at any
particular time, which may affect the Fund's ability to establish or close out a
position; (5) possible impediments to effective portfolio management or the
ability to meet current obligations caused by the segregation of a large
percentage of the Fund's assets to cover its obligations; and (6) the possible
need to defer closing out certain options, futures contracts, options thereon
and forward contracts in order to continue to qualify for the beneficial tax
treatment afforded "regulated investment companies" under the Internal Revenue
Code of 1986, as amended (the "Code"). See the SAI for additional information on
options and futures contracts. Options and futures contracts are commonly known
as "derivative" securities.
 
                                SWAP AGREEMENTS
 
    The Fund may enter into interest rate swaps, currency swaps and other types
of swap agreements such as caps, collars, and floors. In a typical interest rate
swap, one party agrees to make regular payments equal to a floating interest
rate multiplied by a "notional principal amount," in return for payments equal
to a fixed rate multiplied by the same amount, for a specified period of time.
If a swap agreement provides for payments in different currencies, the parties
might agree to exchange the notional principal amount as well. Swaps may also
depend on other prices or rates, such as the value of an index or mortgage
prepayment rates.
 
    In a typical cap or floor agreement, one party agrees to make payments only
under specified circumstances, usually in return for payment of a fee by the
other party. For example, the buyer of an interest rate cap obtains the right to
receive payments to the extent that a specified interest rate exceeds an
agreed-upon level, while the seller of an interest rate floor is obligated to
make payments to the extent that a specified interest rate falls below an
agreed-upon level. An interest rate collar combines elements of buying a cap and
selling a floor.
 
    Swap agreements will tend to shift the Fund's investment exposure from one
type of investment to another. For example, if the Fund agreed to exchange
floating rate payments for fixed rate payments, the swap agreement would tend to
decrease the Fund's exposure to rising interest rates. Caps and floors have an
effect similar to buying or writing options. Depending on how they are used,
swap agreements may increase or decrease the overall volatility of the Fund's
investments and its share price and yield. Swap agreements are commonly known as
"derivative" securities. Because swap agreements are privately negotiated
transactions rather than publicly traded, they may be considered to be illiquid
securities.

- --------------------------------------------------------------------------------
 
    The successful utilization of hedging and risk management transactions
requires skills different from those needed in the selection of the Fund's
portfolio securities and depends on Wellington Management's ability to predict
correctly the direction and degree of movement in interest rates. Although the
Fund believes that the use of the hedging and risk management techniques
described above will benefit the Fund, if Wellington Management's judgment about
the direction or extent of the movement in interest rates is incorrect, the
Fund's overall performance would be worse than if it had not entered into any
such transactions. These activities are commonly used when managing derivative
investments.
 
                              ILLIQUID SECURITIES
 
    The Fund is permitted to invest in illiquid securities. The maximum
percentage of illiquid securities which may be purchased by the Fund is 15% of
its net assets. "Illiquid Securities" are securities that may not be sold or
disposed of in the ordinary course of business within seven days at
approximately the price used to determine the Fund's net asset value. The Fund
may purchase certain restricted securities commonly known as Rule 144A
securities that can be resold to institutions and which may be determined to be
liquid pursuant to policies and guidelines of the Board of Directors.
 
    Under current interpretations of the Securities and Exchange Commission
("SEC") staff, the following securities may be considered illiquid: (1)
repurchase agreements maturing in more than seven days; (2) certain restricted
securities (securities whose public resale is subject to legal or contractual
restrictions); (3) options, with respect to specific securities, not traded on a
national securities exchange that are not readily marketable; and (4) any other
securities in which the Fund may invest that are not readily marketable.
 
                  WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES
 
    The Fund is permitted to purchase or sell securities on a when-issued or
delayed-delivery basis. When-issued or delayed-delivery transactions arise when
securities are purchased or sold with payment and delivery taking place in the
future in order to secure what is considered to be an advantageous price and
yield at the time of entering into the transaction. While the Fund generally
purchases securities on a when-issued basis with the intention of acquiring the
securities, the Fund may sell the securities before the settlement date if
Wellington Management deems it advisable. At the time the Fund makes the
commitment to purchase securities on a when-issued basis, the Fund will record
the transaction and thereafter reflect the value, each day, of such security in
determining net asset value. At the time of delivery of the securities, the
value may be more or less than the purchase price.
 
                           OTHER INVESTMENT COMPANIES
 
    The Fund is permitted to invest in other investment companies. Securities in
certain countries are currently accessible to the Fund only through such
investments. The investment in other investment companies is limited in amount
and will involve the indirect payment of a portion of the expenses, including
advisory fees, of such other investment companies. The Fund will not purchase a
security if, as a result, (1) more than 10% of the Fund's assets would be
invested in securities of other investment companies, (2) such purchase would
result in more than 3% of the total outstanding voting securities of any one
such investment company being held by the Fund or (3) more than 5% of the Fund's
assets would be invested in any one such investment company.
 
                          PORTFOLIO SECURITIES LENDING
 
    The Fund may lend its portfolio securities to broker/ dealers and other
institutions as a means of earning interest income. Delays or losses could
result if a borrower of portfolio securities becomes bankrupt or defaults on its
obligation to return the loaned securities. The Fund may lend securities only
if: (1) the loan is fully secured by appropriate collateral at all times as
determined by HL Advisors; and (2) the value of all loaned securities of the
Fund is not more than 33 1/3% of the Fund's total assets.
 
                               OTHER RISK FACTORS
 
    As mutual funds that primarily invest in equity and/or debt securities, the
Fund is subject to market risk, i.e., the possibility that equity and/or debt
prices in general will decline over short or even extended periods of time. The
financial markets tend to be cyclical, with periods when security prices
generally rise and periods when security prices generally decline.
 
    The value of the debt securities in which the Fund invests will tend to
increase when interest rates are falling and to decrease when interest rates are
rising.
 
    The Fund should not be considered to be a complete investment program in and
of itself. Each prospective purchaser should take into account his or her own
investment objectives as well as his or her other investments when considering
the purchase of shares of the Fund.
 
    There can be no assurance that the investment objectives of the Fund will be
met. In addition, the risk inherent in investing in the Fund is common to any
security -- the net asset value will fluctuate in response to changes in
economic conditions, interest rates and the market's perception of the
underlying portfolio securities held by the Fund.

- --------------------------------------------------------------------------------
 
    In pursuit of a Fund's investment objective, Wellington Management attempts
to select appropriate individual securities for inclusion in the Fund's
portfolio. In addition, Wellington Management attempts to successfully forecast
market trends and increase investments in the types of securities best suited to
take advantage of such trends. Thus, the investor is dependent on Wellington
Management's success not only in selecting individual securities, but also in
identifying the appropriate mix of securities consistent with the Fund's
investment objective.
 
   
    The services provided to the Fund by Hartford Life, HL Advisors, HIMCO,
Wellington Management and other service providers, depend on the smooth
functioning of their computer systems. Many computer software systems in use
today cannot distinguish the year 2000 from the year 1900 because of the way
dates are encoded and calculated. That failure could have a negative impact on
the handling of securities trades, pricing and account services. Hartford Life,
HL Advisors, HIMCO, Wellington Management and other service providers have been
actively working on necessary changes to their computer systems to deal with the
year 2000 issue and expect that their systems will be adapted in time for that
event.
    
 
                             INVESTMENT LIMITATIONS
 
    The Fund has adopted certain limitations in an attempt to reduce its
exposure to specific situations. Some of these limitations are that the Fund
will not:
 
(a) invest more than 25% of its assets in any one industry;
 
(b) borrow money, except from banks, and then only in amounts not exceeding
    33 1/3% of the value of the Fund's total assets (although for purposes of
    this restriction reverse repurchase agreements are not considered
    borrowings, as a non-fundamental operating policy, the Fund will limit
    combined borrowings and reverse repurchase transactions to 33 1/3% of the
    value of the Fund's total assets);
 
(c) with respect to 75% of the value of the Fund's total assets, purchase the
    securities of any issuer (other than cash, cash items or securities issued
    or guaranteed by the U.S. Government, its agencies, instrumentalities or
    authorities) if:
 
    (1) such purchase would cause more than 5% of the Fund's total assets taken
        at market value to be invested in the securities of such issuer; or
 
    (2) such purchase would at the time result in more than 10% of the
        outstanding voting securities of such issuer being held by the Fund.
 
    These investment restrictions are considered at the time investment
securities are purchased. The limitations described above, except as noted under
(b), and those listed under Fundamental Restrictions of the Funds in the SAI,
are considered fundamental and as such can only be changed with the approval of
a majority of the Fund's shareholders.
 
                             MANAGEMENT OF THE FUND
 
    The Fund's Board of Directors manages the business and affairs of the Fund
and takes action on all matters not reserved for the shareholders, including the
annual election of officers of the Fund who carry out all orders and resolutions
of the Board of Directors and carry out functions relating to the day to day
management of the affairs of the Fund.
 
                              MANAGEMENT SERVICES
 
    HL Advisors serves as investment manager to the Fund pursuant to a written
agreement entered into between HL Advisors and the Fund. Pursuant to such
agreement HL Advisors has overall investment supervisory responsibility for the
Fund. In addition, Hartford Life Insurance Company ("Hartford Life"), an
affiliate of HL Advisors, provides administrative personnel, services, equipment
and facilities and office space for proper operation of the Fund. HL Advisors
has contracted with Wellington Management for the provision of day to day
investment management services to the Fund. The Fund pays a fee to HL Advisors,
a portion of which may be used to compensate Wellington Management.
 
    For services rendered to the Fund, HL Advisors charges a monthly fee based
on the following annual rates as applied to the average of the calculated daily
net asset value of the Fund.

                   INVESTMENT SUB-ADVISORY AND OTHER SERVICES
 
    Wellington Management serves as sub-adviser to the Fund pursuant to a
written contract entered into between HL Advisors and Wellington Management.
 
    In connection with the services provided to the Funds, Wellington Management
makes all determinations with respect to the purchase and sale of portfolio
securities (subject to the terms and conditions of the investment objectives,
policies and restrictions of the Fund and to the general supervision of the
Fund's Boards of Directors and HL Advisors) and places, in the name of the Fund,
all orders for execution of the Fund's portfolio transactions. In conjunction
with such activities, Wellington Management regularly furnishes reports to the
Fund's Boards of Directors concerning economic forecasts, investment strategy,
portfolio activity and performance of the Fund.
 
    Wellington Management charges a quarterly fee to HL Advisors. The Fund does
not pay Wellington Management's fee nor any part thereof, nor does the Fund have
any obligation or responsibility to do so. Wellington Management's quarterly fee
is based upon the following annual rates as applied to the average of the
calculated daily net asset value of the Fund.

    Wellington Management has agreed to waive 100% of its sub-advisory fee until
shareholder assets (excluding assets contributed by HL Advisors or its
affiliates) reach $50 million.
 
    Wellington Management is a professional investment counseling firm which
provides investment services to investment companies, employee benefit plans,
endowments, foundations and other institutions and individuals. Wellington
Management and its predecessor organizations have provided investment advisory
services since 1928. As of September 30, 1997, Wellington Management held
discretionary management authority with respect to approximately $169 billion of
client assets. Wellington Management, 75 State Street, Boston, MA 02109, is a
Massachusetts limited liability partnership, of which the following persons are
managing partners: Robert W. Doran, Duncan M. McFarland and John R. Ryan.
 
                               PORTFOLIO MANAGER
 
    James A. Rullo, CFA and Vice President of Wellington Management, serves as
portfolio manager to the Fund. Prior to joining Wellington Management in 1994 as
a quantitative analyst and portfolio manager, Mr. Rullo was a portfolio manager
with PanAgora Asset Management from 1991 to 1994 and prior to that with The
Boston Company from 1987.
 
                               PORTFOLIO TURNOVER
 
    The Fund may sell a portfolio investment soon after its acquisition if
Wellington Management believes that such a disposition is in the Fund's best
interest. A high rate of portfolio turnover involves correspondingly greater
brokerage commission expenses and other transaction costs, which must be
ultimately borne by a Fund's shareholders. High portfolio turnover may result in
the realization of substantial capital gains; distributions derived from such
gains may be treated as ordinary income for Federal income tax purposes.
Although it is not possible to predict future portfolio turnover rates
accurately, and such rates may vary from year to year, it is anticipated that
the Fund's portfolio turnover rate will not exceed 100%.
 
                             BROKERAGE COMMISSIONS
 
    Although the Rules of Fair Practice of the National Association of
Securities Dealers, Inc. prohibit its members from seeking orders for the
execution of investment company portfolio transactions on the basis of their
sales of investment company shares, under such rules, sales of investment
company shares may be considered in selecting brokers to effect portfolio
transactions. Accordingly, some portfolio transactions are, subject to such
Rules and to obtaining best prices and executions, effected through dealers who
sell shares of the Fund. Wellington Management may also select an affiliated
broker-dealer to execute transactions for the Fund, provided that the
commissions, fees or other remuneration paid to such affiliated broker are
reasonable and fair as compared to that paid to non-affiliated brokers for
comparable transactions.
 
                            ADMINISTRATIVE SERVICES
                                  FOR THE FUND
 
    An Administrative Services Agreement between the Fund and Hartford Life
provides that Hartford Life will manage the business affairs and provide
administrative services to the Fund. Under the terms of this Agreement, Hartford
Life will provide the following: administrative personnel, services, equipment
and facilities and office space for proper operation of the Fund. Hartford Life
has also agreed to arrange for the provision of additional

- --------------------------------------------------------------------------------
 
services necessary for the proper operation of the Fund, although the Fund pays
for these services directly. See "Expenses of the Fund." As compensation for the
services to be performed by Hartford Life, the Fund pays to Hartford Life, as
promptly as possible after the last day of each month, a monthly fee equal to
the annual rate of .175% of the average daily net assets of the Fund.
 
                              EXPENSES OF THE FUND
 
    The Fund assumes and pays the following costs and expenses: interest; taxes;
brokerage charges (which may be to affiliated broker-dealers); costs of
preparing, printing and filing any amendments or supplements to the registration
forms of the Fund and its securities; all federal and state registration,
qualification and filing costs and fees, (except the initial costs and fees,
which will be borne by Hartford Life), issuance and redemption expenses,
transfer agency and dividend and distribution disbursing agency costs and
expenses; custodian fees and expenses; accounting, auditing and legal expenses;
fidelity bond and other insurance premiums; fees and salaries of directors,
officers and employees of the Fund other than those who are also officers of
Hartford Life or its affiliates; industry membership dues; all annual and
semiannual reports and prospectuses mailed to the Fund's shareholders as well as
all quarterly, annual and any other periodic report required to be filed with
the SEC or with any state; any notices required by a federal or state regulatory
authority, and any proxy solicitation materials directed to the Fund's
shareholders as well as all printing, mailing and tabulation costs incurred in
connection therewith, and any expenses incurred in connection with the holding
of meetings of the Fund's shareholders and other miscellaneous expenses related
directly to the Fund's operations and interest.
 
                        PERFORMANCE RELATED INFORMATION
 
    The Fund may advertise certain performance related information. Performance
information about the Fund is based on the Fund's past performance only and is
no indication of future performance.
 
    The Fund may include its total return in advertisements or other sales
material. When the Fund advertises its total return, it will usually be
calculated for one year, five years, and ten years or some other relevant
periods if the Fund has not been in existence for at least ten years. Total
return is measured by comparing the value of an investment in the Fund at the
beginning of the relevant period to the value of the investment at the end of
the period (assuming immediate reinvestment of any dividends or capital gains
distributions).
 
                                   DIVIDENDS
 
    The shareholders of the Fund shall be entitled to receive such dividends as
may be declared by the Fund's Board of Directors, from time to time based upon
the investment performance of the assets making up the Fund's portfolio. The
policy with respect to the Fund is to pay dividends from net investment income
and to make distributions of realized capital gains, if any, at least once each
year.
 
    Such dividends and distributions will be automatically invested in
additional full or fractional shares monthly on the last business day of each
month at the per share net asset value on that date. Provision is also made to
pay such dividends and distributions in cash if requested. Such dividends and
distributions will be in cash or in full or fractional shares of the Fund at net
asset value.
 
                                DETERMINATION OF
                                NET ASSET VALUE
 
    The net asset value per share is determined for the Fund as of the close of
the NYSE (normally 4:00 p.m. Eastern Time) on each regular business day (as
previously defined) by dividing the value of the Fund's net assets by the number
of shares outstanding. The assets of the Fund are valued primarily on the basis
of market quotations. If quotations are not readily available, assets are valued
by a method that the Board of Directors believes accurately reflects fair value.
Foreign securities are valued on the basis of quotations from the primary market
in which they are traded, and are translated from the local currency into U.S.
dollars using current exchange rates. With respect to the Fund, short-term
investments that will mature in 60 days or less are also valued at amortized
cost, which approximates market value.
 
                            PURCHASE OF FUND SHARES
 
    Fund shares are made available to serve as the underlying investment vehicle
for variable annuity and variable life insurance separate accounts of The
Hartford Life Insurance Companies. Shares of the Fund are sold by Hartford
Securities Distribution Company, Inc. (the "Distributor") on a no-load basis at
their net asset values. See "Determination of Net Asset Value" and "Sale and
Redemption of Shares."
 
    It is conceivable that in the future it may be disadvantageous for variable
annuity separate accounts and variable life insurance separate accounts to
invest in the Funds simultaneously. Although The Hartford Life Insurance
Companies and the Funds do not currently foresee any such disadvantages either
to variable annuity contract owners or variable life insurance policy owners,
each Fund's Board of

Directors intends to monitor events in order to identify any material conflicts
between such contract owners and policy owners and to determine what action, if
any, should be taken in response thereto. If the Board of Directors of a Fund
were to conclude that separate funds should be established for variable life and
variable annuity separate accounts, the variable life and variable annuity
contract holders would not bear any expenses attendant to the establishment of
such separate funds.
 
    The Fund offers investors two different classes of shares -- Class IA and
Class IB. Class IA shares are offered by this Prospectus. Class IB shares are
offered by a separate prospectus in connection with a variable annuity product.
The different classes of shares represent investments in the same portfolio of
securities but are subject to different expenses and will likely have different
share prices.
 
                              SALE AND REDEMPTION
                                   OF SHARES
 
    The shares of the Fund are sold and redeemed by the Fund at their net asset
value next determined after receipt of a purchase or redemption order in good
order in writing at its home office, P.O. Box 2999, Hartford, CT 06104-2999. The
value of shares redeemed may be more or less than original cost, depending upon
the market value of the portfolio securities at the time of redemption. Payment
for shares redeemed will be made within seven days after the redemption request
is received in proper form by the Fund. However, the right to redeem Fund shares
may be suspended or payment therefor postponed for any period during which: (1)
trading on the NYSE is closed for other than weekends and holidays; (2) an
emergency exists, as determined by the SEC, as a result of which (a) disposal by
the Fund of securities owned by it is not reasonably practicable, or (b) it is
not reasonably practicable for the Fund to determine fairly the value of its net
assets; or (3) the SEC by order so permits for the protection of stockholders of
the Fund.
 
                              FEDERAL INCOME TAXES
 
    The Fund has elected and intends to qualify under Subchapter M of the Code.
The Fund intends to distribute all of its net income and gains to shareholders.
Such distributions are taxable income and capital gains. The Fund will inform
shareholders of the amount and nature of such income and gains. The Fund may be
subject to a 4% nondeductible excise tax as well as an income tax measured with
respect to certain undistributed amounts of income and capital gain. The Fund
expects to make such additional distributions of net investment income as are
necessary to avoid the application of these taxes. For a discussion of the tax
implications of a purchase or sale of the Fund's shares by the insurer,
reference should be made to the section entitled "Federal Tax Considerations" in
the appropriate separate account prospectus.
 
    If eligible, the Fund may make an election to pass through to its
shareholders, The Hartford Life Insurance Companies, a credit for any foreign
taxes paid during the year. If such election is made, the pass-through of the
foreign tax credit will result in additional taxable income and income tax to
The Hartford Life Insurance Companies. The amount of additional tax may be more
than offset by the foreign tax credits which are passed through. These foreign
tax credits may provide a benefit to The Hartford Life Insurance Companies.
 
                    OWNERSHIP AND CAPITALIZATION OF THE FUND
 
                                 CAPITAL STOCK
 
    As of the date of this prospectus, the authorized capital stock of the Fund
consists of 3 billion shares at a par value of $.001 per share.
 
    The Board of Directors is authorized, without further shareholder approval,
to authorize additional shares and to classify and reclassify the Fund into one
or more classes. Accordingly, the Directors have authorized the issuance of two
classes of shares of the Fund designated as Class IA and Class IB shares. The
shares of each class represent an interest in the same portfolio of investments
of the Fund and have equal rights as to voting, redemption, and liquidation.
However, each class bears different expenses and therefore the net asset values
of the two classes and any dividends declared may differ between the two
classes.
 
                                     VOTING
 
    Each shareholder shall be entitled to one vote for each share of the Fund
held upon all matters submitted to the shareholders generally. Class specific
issues, such as a modification to a Rule 12b-1 plan that could materially
increase fees, will be voted on only by the affected class. With respect to the
Fund's shares issued as described above under "Purchase of Fund Shares," as well
as Fund shares which are not otherwise attributable to variable annuity contract
owners or variable life policy holders, The Hartford Life Insurance Companies
shall be the shareholders of record. Each of The Hartford Life Insurance
Companies will vote all Fund shares, pro rata, according to the written
instructions of the contract owners of the variable annuity contracts and the
policy holders of the variable life contracts issued by it using the Fund as
investment vehicles. This position is consistent with the policy of the SEC
staff.

                                   APPENDIX A
 
    The rating information which follows describes how the rating services
mentioned presently rate the described securities. No reliance is made upon the
rating firms as "experts" as that term is defined for securities purposes.
Rather, reliance on this information is on the basis that such ratings have
become generally accepted in the investment business.
 
                                RATING OF BONDS
 
    MOODY'S INVESTORS SERVICE, INC. ("MOODY'S")
 
    Aaa -- Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edge." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.
 
    Aa -- Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long term risks appear somewhat larger than in Aaa securities.
 
    A -- Bonds which are rated A possess many favorable investment attributes
and are to be considered as upper medium grade obligations. Factors giving
security to principal and interest are considered adequate but elements may be
present which suggest a susceptibility to impairment sometime in the future.
 
    Baa -- Bonds which are rated Baa are considered as medium grade obligations,
i.e., they are neither highly protected nor poorly secured. Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.
 
    Ba -- Bonds which are rated Ba are judged to have speculative elements;
their future cannot be considered as well assured. Often the protection of
interest and principal payments may be very moderate and thereby not well
safeguarded during both good and bad times over the future. Uncertainty of
position characterizes bonds in this class.
 
    B -- Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.
 
    Caa -- Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.
 
    Ca -- Bonds which are rated Ca represent obligations which are speculative
in a high degree. Such issues are often in default or have other marked
shortcomings.
 
    C -- Bonds which are rated C are the lowest rated class of bonds and issues
so rated can be regarded as having extremely poor prospects of ever earning any
real investment standing.
 
    STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
    AAA -- Bonds rated AAA are the highest grade obligations. Capacity to pay
interest and repay principal is extremely strong.
 
    AA -- Bonds rated AA have a very strong capacity to pay interest and repay
principal and differ from AAA issues only in small degree.
 
    A -- Bonds rated A have a very strong capacity to pay interest and repay
principal although they are somewhat more susceptible to the considerable
investment strength but are not entirely free from adverse effects of changes in
circumstances and economic conditions than debt in the highest rated categories.
 
    BBB -- Bonds rated BBB and regarded as having an adequate capacity to pay
interest and repay principal. Whereas they normally exhibit adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category then in higher rated categories.
 
    BB, B, CCC, CC, C -- Debt rated BB, B, CCC, CC, and C is regarded, on
balance, as predominantly speculative with respect to the issuer's capacity to
pay interest and repay principal in accordance with the terms of the obligation.
While such debt will likely have some quality and protective characteristics,
these are outweighed by large uncertainties or major risk exposures to adverse
conditions.
 
                           RATING OF COMMERCIAL PAPER
 
    Purchases of corporate debt securities used for short-term investment,
generally called commercial paper, will be limited to the top two grades of
Moody's, Standard & Poor's, Duff & Phelps, Fitch Investor Services and Thomson
Bank Watch or other NRSROs (nationally recognized statistical

rating organizations) rating services and will be an eligible security under
Rule 2a-7.
 
    MOODY'S
 
    Issuers rated Prime-1 (or related supporting institutions) have a superior
capacity for repayment of short-term promissory obligations. Prime-1 repayment
capacity will normally be evidenced by the following characteristics:
 
- - Leading market positions in well-established industries.
 
- - High rates of return on funds employed.
 
- - Conservative capitalization structures with moderate reliance on debt and
  ample asset protection.
 
- - Broad margins in earnings coverage of fixed financial charges and high
  internal cash generation.
 
- - Well-established access to a range of financial markets and assured sources of
  alternate liquidity.
 
    Issuers rated Prime-2 (or related supporting institutions) have a strong
capacity for repayment of short-term promissory obligations. This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, will be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.
 
    Issuers rated Prime-3 (or related supporting institutions) have an
acceptable capacity for repayment of short-term promissory obligations. The
effect of industry characteristics and market composition may be more
pronounced. Variability in earnings and profitability may result in changes in
the level of debt protection measurements and the requirement for relatively
high financial leverage. Adequate alternate liquidity is maintained.
 
    Issuers rated Not Prime do not fall within any of the Prime rating
categories.
 
    STANDARD & POOR'S
 
    The relative strength or weakness of the following factors determines
whether the issuer's commercial paper is rated A-1 or A-2.
 
- - Liquidity ratios are adequate to meet cash requirements.
 
    Liquidity ratios are basically as follows, broken down by the type of
issuer:
 
    Industrial Company: acid test ratio, cash flow as a percent of current
liabilities, short-term debt as a percent of current liabilities, short-term
debt as a percent of current assets.
 
    Utility: current liabilities as a percent of revenues, cash flow as a
percent of current liabilities, short-term debt as a percent of capitalization.
 
    Finance Company: current ratio, current liabilities as a percent of net
receivables, current liabilities as a percent of total liabilities.
 
- - The long-term senior debt rating is "A" or better; in some instances "BBB"
  credits may be allowed if other factors outweigh the "BBB".
 
- - The issuer has access to at least two additional channels of borrowing.
 
- - Basic earnings and cash flow have an upward trend with allowances made for
  unusual circumstances.
 
- - Typically, the issuer's industry is well established and the issuer has a
  strong position within its industry.
 
- - The reliability and quality of management are unquestioned.

- --------------------------------------------------------------------------------
 
                          INTRODUCTION TO THE HARTFORD
                           GROWTH AND INCOME HLS FUND
 
    The Fund is a diversified series of Hartford Series Fund, Inc. (the
"Company"), an open-end management investment company which was organized as a
Maryland corporation on January 15, 1998. The Fund commenced operations on
            , 1998. The Fund is made available to serve as the underlying
investment vehicle for certain variable annuity and variable life insurance
separate accounts of The Hartford Life Insurance Companies.
 
    The Fund offers Class IA and Class IB shares. Only Class IB shares of the
Fund are offered by this Prospectus. Each Class incurs different expenses which
will affect performance. Class IA shares are offered pursuant to another
prospectus and are subject to the same expenses as the Class IB shares, but
unlike the Class IB shares they are not subject to distribution fees imposed
pursuant to a distribution plan ("Distribution Plan") adopted under Rule 12b-1
of the Investment Company Act of 1940 (the "1940 Act"). Inquiries regarding
Class IA shares should be addressed to Hartford Growth and Income HLS Fund, c/o
Individual Annuity Operations, P.O. Box 2999, Hartford, CT 06104-2999 or by
calling 1-800-862-6668.
 
    HL Investment Advisors, Inc. ("HL Advisors") is the investment manager to
the Fund. In addition, under HL Advisors' general management, Wellington
Management Company, LLP ("Wellington Management") serves as sub-adviser to the
Fund.
 
   
    HL Advisors was incorporated in Connecticut in 1981 and is a majority-owned
indirect subsidiary of The Hartford Financial Services Group, Inc. ("The
Hartford"), a Connecticut insurance holding company with over $100 billion in
assets. Wellington Management, a Massachusetts limited liability partnership, is
a professional investment counseling firm that provides services to investment
companies, employee benefit plans, endowments, foundations and other
institutions and individuals. Wellington Management and its predecessor
organizations have provided investment advisory services since 1928. As of
December 31, 1997, HL Advisors had investment management authority with respect
to approximately $24 billion of assets for various clients. As of the same date,
Wellington Management had investment management authority with respect to
approximately $175 billion of assets for various clients.
    
 
                            INVESTMENT OBJECTIVE AND
                               STYLE OF THE FUND
 
    The Fund is subject to certain fundamental investment restrictions that are
enumerated in detail in the SAI and may not be changed without shareholder
approval. All other investment policies (including the Fund's investment
objective) are non-fundamental and may be changed by the Board of Directors
without shareholder approval. Stated below is the investment objective and
investment style for the Fund. For a description of the Fund's investment
policies and risk factors, see "Common Investment Policies and Risk Factors."
 
    INVESTMENT OBJECTIVE.
 
   
    The Growth and Income HLS Fund seeks growth of capital and current income by
investing primarily in equity securities with earnings growth potential and
steady or rising dividends.
    
 
    INVESTMENT STYLE.
 
    The Growth and Income HLS Fund invests in a diversified portfolio of
primarily equity securities that typically have steady or rising dividends and
whose prospects for capital appreciation are considered favorable by Wellington
Management. Wellington Management uses fundamental analysis to evaluate a
security for purchase or sale by the Fund. Fundamental analysis involves the
assessment of a company through such factors as its business environment,
management, balance sheet, income statement, anticipated earnings, revenues,
dividends, and other related measures of value. Wellington Management then uses
proprietary quantitative techniques to affirm its fundamental evaluation of a
security. The quantitative techniques evaluate a security using valuation
analysis, which includes use of a dividend discount model and cash flow
analysis, combined with momentum analysis, which includes an assessment of a
company's earnings momentum and stock price momentum. The quantitative
techniques look to affirm the fundamental evaluation by identifying those
securities that are attractive from the fundamental perspective and are also
both inexpensive based on the quantitative valuation factors and timely
according to the quantitative momentum factors. The Fund's portfolio will be
broadly diversified by industry and company. Up to 20% of the Fund's total
assets may be invested in securities of non-U.S. companies.

- --------------------------------------------------------------------------------
 
                  COMMON INVESTMENT POLICIES AND RISK FACTORS
 
          MONEY MARKET INSTRUMENTS AND TEMPORARY INVESTMENT STRATEGIES
 
   
    The Fund may hold cash and invest in high quality money market instruments
under appropriate circumstances as determined by Wellington Management. The Fund
may invest up to 100% of its assets in cash or money market instruments only for
temporary defensive purposes.
    
 
    Money market instruments include: (1) banker's acceptances; (2) obligations
of governments (whether U.S. or non-U.S.) and their agencies and
instrumentalities; (3) short-term corporate obligations, including commercial
paper, notes, and bonds; (4) other short-term debt obligations; (5) obligations
of U.S. banks, non-U.S. branches of U.S. banks (Eurodollars), U.S. branches and
agencies of non-U.S. banks (Yankee dollars), and non-U.S. branches of non-U.S.
banks; (6) asset-backed securities; and (7) repurchase agreements.
 
                             REPURCHASE AGREEMENTS
 
    The Fund is permitted to enter into fully collateralized repurchase
agreements. A repurchase agreement is an agreement by which the seller of a
security agrees to repurchase the security sold at a mutually agreed upon time
and price. It may also be viewed as the loan of money by the Fund to the seller.
The resale price would be in excess of the purchase price, reflecting an agreed
upon market interest rate. Delays or losses could result if the other party to
the agreement defaults or becomes insolvent. The Fund's Board of Directors has
established standards for evaluation of the creditworthiness of the banks and
securities dealers with which the Fund may engage in repurchase agreements and
monitors on a quarterly basis Wellington Management's compliance with such
standards.
 
                         REVERSE REPURCHASE AGREEMENTS
 
    The Fund may also enter into reverse repurchase agreements. Reverse
repurchase agreements involve sales by the Fund of portfolio assets concurrently
with an agreement by the Fund to repurchase the same assets at a later date at a
fixed price. Reverse repurchase agreements carry the risk that the market value
of the securities which the Fund is obligated to repurchase may decline below
the repurchase price. A reverse repurchase agreement is viewed as a
collateralized borrowing by the Fund. Borrowing magnifies the potential for gain
or loss on the portfolio securities of the Fund and, therefore, increases the
possibility of fluctuation in the Fund's net asset value. The Fund will
establish a segregated account with the Fund's custodian bank in which the Fund
will maintain liquid assets equal in value to the Fund's obligations in respect
of reverse repurchase agreements. As a non-fundamental policy, the Fund will not
enter into reverse repurchase transactions if the combination of all borrowings
from banks and the value of all reverse repurchase agreements for the Fund
equals more than 33 1/3% of the value of the Fund's total assets.
 
                                DEBT SECURITIES
 
    The Fund is permitted to invest in debt securities including: (1) securities
issued or guaranteed as to principal or interest by the U.S. Government, its
agencies or instrumentalities; (2) debt securities issued or guaranteed by U.S.
corporations or other issuers (including foreign governments or corporations);
and (3) securities issued or guaranteed as to principal or interest by a
sovereign government or one of its agencies or political subdivisions,
supranational entities such as development banks, non-U.S. corporations, banks
or bank holding companies, or other non-U.S. issuers.
 
                        INVESTMENT GRADE DEBT SECURITIES
 
    The Fund is permitted to invest in debt securities rated within the four
highest rating categories (i.e., Aaa, Aa, A or Baa by Moody's or AAA, AA, A or
BBB by S&P), or, if unrated, securities of comparable quality as determined by
Wellington Management. These securities are generally referred to as "investment
grade securities." Each rating category has within it different gradations or
sub-categories. If the Fund is authorized to invest in a certain rating
category, the Fund is also permitted to invest in any of the sub-categories or
gradations within that rating category. If a security is downgraded to a rating
category which does not qualify for investment, Wellington Management will use
its discretion on whether to hold or sell based upon its opinion on the best
method to maximize value for shareholders over the long term. Debt securities
carrying the fourth highest rating (i.e., "Baa" by Moody's and "BBB" by S&P),
and unrated securities of comparable quality (as determined by Wellington
Management) are viewed as having adequate capacity for payment of principal and
interest, but do involve a higher degree of risk than that associated with
investments in debt securities in the higher rating categories.
 
                      HIGH YIELD-HIGH RISK DEBT SECURITIES
 
    The Fund may invest up to 5% of its assets in high yield debt securities
(i.e., rated as low as "C" by Moody's or S&P, and unrated securities of
comparable quality as determined by Wellington Management). Securities rated
below investment grade are commonly referred to as "high yield-high risk
securities" or "junk bonds". Each rating category has within it different
gradations or sub-categories. If the Fund is authorized to invest in a certain
rating category, the Fund

HARTFORD GROWTH AND INCOME HLS FUND                                            5
- --------------------------------------------------------------------------------
 
is also permitted to invest in any of the sub-categories or gradations within
that rating category. If a security is downgraded to a rating category which
does not qualify for investment, Wellington Management will use its discretion
on whether to hold or sell based upon its opinion on the best method to maximize
value for shareholders over the long term. Securities in the rating categories
below "Baa" as determined by Moody's and "BBB" as determined by S&P are
considered to be of poor standing and predominantly speculative. The rating
services' descriptions of securities are set forth in Appendix A. High
yield-high risk debt securities are considered speculative with respect to the
issuer's capacity to pay interest and repay principal in accordance with the
terms of the obligations. Accordingly, it is possible that these types of
factors could, in certain instances, reduce the value of securities held by the
Fund with a commensurate effect on the value of the Fund's shares.
 
                               EQUITY SECURITIES
 
    The Fund may invest in equity securities including common stocks, preferred
stocks, convertible preferred stock and rights to acquire such securities. In
addition, the Fund may invest in securities such as bonds, debentures and
corporate notes which are convertible into common stock at the option of the
holder.
 
                        SMALL CAPITALIZATION SECURITIES
 
    The Fund may invest in equity securities (including securities issued in
initial public offerings) of companies which have less than $2 billion in market
capitalization ("Small Capitalization Securities"). Because the issuers of Small
Capitalization Securities tend to be smaller or less well-established companies,
they may have limited product lines, market share or financial resources and may
have less historical data with respect to operations and management. As a
result, Small Capitalization Securities are often less marketable and experience
a higher level of price volatility than securities of larger or more
well-established companies. In addition, companies whose securities are offered
in initial public offerings may be more dependent on a limited number of key
employees. Because securities issued in initial public offerings are being
offered to the public for the first time, the market for such securities may be
inefficient and less liquid.
 
                              NON-U.S. SECURITIES
 
    The Fund is permitted to invest up to 20% of its assets in non-U.S.
securities. The Fund may invest in American Depositary Receipts ("ADRs") and
Global Depositary Receipts ("GDRs"). ADRs are certificates issued by a U.S. bank
or trust company and represent the right to receive non-U.S. securities. ADRs
are traded on a U.S. securities exchange, or in an over-the-counter market, and
are denominated in U.S. dollars. GDRs are certificates issued globally and
evidence a similar ownership arrangement. GDRs are traded on non-U.S. securities
exchanges and are denominated in non-U.S. currencies. The value of an ADR or a
GDR will fluctuate with the value of the underlying security, will reflect any
changes in exchange rates and otherwise will involve risks associated with
investing in non-U.S. securities.
 
    When selecting non-U.S. securities Wellington Management will evaluate the
economic and political climate and the principal securities markets of the
country in which the company is located. Investing in non-U.S. securities
involves considerations and potential risks not typically associated with
investing in securities issued by U.S. companies. Less information may be
available about non-U.S. companies than about U.S. companies and non-U.S.
companies generally are not subject to uniform accounting, auditing and
financial reporting standards or to other regulatory practices and requirements
comparable to those applicable to U.S. companies. The values of non-U.S.
securities are affected by changes in currency rates or exchange control
regulations, restrictions or prohibitions on the repatriation of non-U.S.
currencies, application of non-U.S. tax laws, including withholding taxes,
changes in governmental administration or economic or monetary policy (in the
U.S. or outside the U.S.) or changed circumstances in dealings between nations.
Costs are also incurred in connection with conversions between various
currencies. The Fund may invest up to 25% of its assets in companies located in
emerging countries. Compared to the United States and other developed countries,
developing countries may have relatively unstable governments, economies based
on only a few industries, and securities markets that are less liquid and trade
a small number of securities. Prices on these exchanges tend to be volatile and,
in the past, securities in these countries have offered greater potential for
gain (as well as loss) than securities of companies located in developed
countries. See the SAI for additional risk disclosure concerning non-U.S.
securities.
 
                             CURRENCY TRANSACTIONS
 
    The Fund may engage in currency transactions to hedge the value of portfolio
securities denominated in particular currencies against fluctuations in relative
value. Currency transactions include forward currency contracts, currency swaps,
exchange-listed and over-the-counter ("OTC") currency futures contracts and
options thereon and exchange listed and OTC options on currencies.
 
    Forward currency contracts involve a privately negotiated 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. Currency swaps are agreements to exchange
cash flows based on the notional difference between or among two or more
currencies. See "Swap Agreements."
<PAGE>
6                                            HARTFORD GROWTH AND INCOME HLS FUND
- --------------------------------------------------------------------------------
 
    The use of currency transactions to protect the value of the Fund's assets
against a decline in the value of a currency does not eliminate potential losses
arising from fluctuations in the value of the Fund's underlying securities.
Further, the Fund may enter into currency transactions only with counterparties
that Wellington Management deems to be creditworthy.
 
    The Fund may also enter into options and futures contracts relative to
foreign currency to hedge against fluctuations in foreign currency rates. See
"Options and Futures Contracts" for a discussion of risk factors relating to
foreign currency transactions including related options and futures contracts.
 
                         OPTIONS AND FUTURES CONTRACTS
 
    The Fund may employ certain hedging, income enhancement and risk management
techniques involving options and futures contracts, though such techniques may
also result in losses to the Fund. The Fund may write covered call options or
purchase put and call options on individual securities, write covered put and
call options and purchase put and call options on foreign currencies, aggregates
of equity and debt securities, indices of prices of equity and debt securities
and other financial indices, and enter into futures contracts and options
thereon for the purchase or sale of aggregates of equity and debt securities,
indices of equity and debt securities and other financial indices.
 
    The Fund may write covered options only. "Covered" means that, so long as
the Fund is obligated as the writer of an option, it will own either the
underlying securities or currency or an option to purchase or sell the same
underlying securities or currency having an expiration date not earlier than the
expiration date of the covered option and an exercise price equal to or less
than the exercise price of the covered option, or will establish or maintain
with its custodian for the term of the option a "segregated account" consisting
of cash, U.S. Government securities or other liquid, high grade debt obligations
having a value equal to the fluctuating market value of the optioned securities
or currencies. The Fund receives a premium from writing a call or put option,
which increases the Fund's return if the option expires unexercised or is closed
out at a net profit.
 
    To hedge against fluctuations in currency exchange rates, the Fund may
purchase or sell foreign currency futures contracts, and write put and call
options and purchase put and call options on such futures contracts. To the
extent that the Fund enters into futures contracts, options on futures contracts
and options on foreign currencies that are traded on an exchange regulated by
the Commodities Futures Trading Commission ("CFTC"), in each case that are not
for bona fide hedging purposes (as defined by the CFTC), the aggregate initial
margin and premiums required to establish those non-hedging positions may not
exceed 5% of the liquidation value of the Fund's portfolio, after taking into
account the unrealized profits and unrealized losses on any such contracts the
Fund has entered into.
 
    The Fund's use of options, futures and options thereon and forward currency
contracts (as described under "Currency Transactions") would involve certain
investment risks and transaction costs to which it might not be subject were
such strategies not employed. Such risks include: (1) dependence on the ability
of Wellington Management to predict movements in the prices of individual
securities, fluctuations in the general securities markets or market sections
and movements in interest rates and currency markets; (2) imperfect correlation
between movements in the price of the securities or currencies hedged or used
for cover; (3) the fact that skills and techniques needed to trade options,
futures contracts and options thereon or to use forward currency contracts are
different from those needed to select the securities in which the Fund invests;
(4) lack of assurance that a liquid secondary market will exist for any
particular option, futures contract, option thereon or forward contract at any
particular time, which may affect the Fund's ability to establish or close out a
position; (5) possible impediments to effective portfolio management or the
ability to meet current obligations caused by the segregation of a large
percentage of the Fund's assets to cover its obligations; and (6) the possible
need to defer closing out certain options, futures contracts, options thereon
and forward contracts in order to continue to qualify for the beneficial tax
treatment afforded "regulated investment companies" under the Internal Revenue
Code of 1986, as amended (the "Code"). See the SAI for additional information on
options and futures contracts. Options and futures contracts are commonly known
as "derivative" securities.
 
                                SWAP AGREEMENTS
 
    The Fund may enter into interest rate swaps, currency swaps and other types
of swap agreements such as caps, collars, and floors. In a typical interest rate
swap, one party agrees to make regular payments equal to a floating interest
rate multiplied by a "notional principal amount," in return for payments equal
to a fixed rate multiplied by the same amount, for a specified period of time.
If a swap agreement provides for payments in different currencies, the parties
might agree to exchange the notional principal amount as well. Swaps may also
depend on other prices or rates, such as the value of an index or mortgage
prepayment rates.
 
    In a typical cap or floor agreement, one party agrees to make payments only
under specified circumstances, usually in return for payment of a fee by the
other party. For example, the buyer of an interest rate cap obtains the right to
receive payments to the extent that a specified interest rate exceeds an
agreed-upon level, while the seller of an interest rate floor is obligated to
make payments to the extent that a specified interest rate falls below an
agreed-

HARTFORD GROWTH AND INCOME HLS FUND                                            7
- --------------------------------------------------------------------------------
 
upon level. An interest rate collar combines elements of buying a cap and
selling a floor.
 
    Swap agreements will tend to shift the Fund's investment exposure from one
type of investment to another. For example, if the Fund agreed to exchange
floating rate payments for fixed rate payments, the swap agreement would tend to
decrease the Fund's exposure to rising interest rates. Caps and floors have an
effect similar to buying or writing options. Depending on how they are used,
swap agreements may increase or decrease the overall volatility of the Fund's
investments and its share price and yield. Swap agreements are commonly known as
"derivative" securities. Because swap agreements are privately negotiated
transactions rather than publicly traded, they may be considered to be illiquid
securities.
 
    The successful utilization of hedging and risk management transactions
requires skills different from those needed in the selection of the Fund's
portfolio securities and depends on Wellington Management's ability to predict
correctly the direction and degree of movement in interest rates. Although the
Fund believes that the use of the hedging and risk management techniques
described above will benefit the Fund, if Wellington Management's judgment about
the direction or extent of the movement in interest rates is incorrect, the
Fund's overall performance would be worse than if it had not entered into any
such transactions. These activities are commonly used when managing derivative
investments.
 
                              ILLIQUID SECURITIES
 
    The Fund is permitted to invest in illiquid securities. The maximum
percentage of illiquid securities which may be purchased by the Fund is 15% of
its net assets. "Illiquid Securities" are securities that may not be sold or
disposed of in the ordinary course of business within seven days at
approximately the price used to determine the Fund's net asset value. The Fund
may purchase certain restricted securities commonly known as Rule 144A
securities that can be resold to institutions and which may be determined to be
liquid pursuant to policies and guidelines of the Board of Directors.
 
    Under current interpretations of the Securities and Exchange Commission
("SEC") staff, the following securities may be considered illiquid: (1)
repurchase agreements maturing in more than seven days; (2) certain restricted
securities (securities whose public resale is subject to legal or contractual
restrictions); (3) options, with respect to specific securities, not traded on a
national securities exchange that are not readily marketable; and (4) any other
securities in which the Fund may invest that are not readily marketable.
 
                  WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES
 
    The Fund is permitted to purchase or sell securities on a when-issued or
delayed-delivery basis. When-issued or delayed-delivery transactions arise when
securities are purchased or sold with payment and delivery taking place in the
future in order to secure what is considered to be an advantageous price and
yield at the time of entering into the transaction. While the Fund generally
purchases securities on a when-issued basis with the intention of acquiring the
securities, the Fund may sell the securities before the settlement date if
Wellington Management deems it advisable. At the time the Fund makes the
commitment to purchase securities on a when-issued basis, the Fund will record
the transaction and thereafter reflect the value, each day, of such security in
determining net asset value. At the time of delivery of the securities, the
value may be more or less than the purchase price.
 
                           OTHER INVESTMENT COMPANIES
 
    The Fund is permitted to invest in other investment companies. Securities in
certain countries are currently accessible to the Fund only through such
investments. The investment in other investment companies is limited in amount
and will involve the indirect payment of a portion of the expenses, including
advisory fees, of such other investment companies. The Fund will not purchase a
security if, as a result, (1) more than 10% of the Fund's assets would be
invested in securities of other investment companies, (2) such purchase would
result in more than 3% of the total outstanding voting securities of any one
such investment company being held by the Fund or (3) more than 5% of the Fund's
assets would be invested in any one such investment company.
 
                          PORTFOLIO SECURITIES LENDING
 
    The Fund may lend its portfolio securities to broker/ dealers and other
institutions as a means of earning interest income. Delays or losses could
result if a borrower of portfolio securities becomes bankrupt or defaults on its
obligation to return the loaned securities. The Fund may lend securities only
if: (1) the loan is fully secured by appropriate collateral at all times as
determined by HL Advisors; and (2) the value of all loaned securities of the
Fund is not more than 33 1/3% of the Fund's total assets.
 
                               OTHER RISK FACTORS
 
    As mutual funds that primarily invest in equity and/or debt securities, the
Fund is subject to market risk, i.e., the possibility that equity and/or debt
prices in general will decline over short or even extended periods of time. The
financial markets tend to be cyclical, with periods when security prices
generally rise and periods when security prices generally decline.
<PAGE>
8                                            HARTFORD GROWTH AND INCOME HLS FUND
- --------------------------------------------------------------------------------
 
    The value of the debt securities in which the Fund invests will tend to
increase when interest rates are falling and to decrease when interest rates are
rising.
 
    The Fund should not be considered to be a complete investment program in and
of itself. Each prospective purchaser should take into account his or her own
investment objectives as well as his or her other investments when considering
the purchase of shares of the Fund.
 
    There can be no assurance that the investment objectives of the Fund will be
met. In addition, the risk inherent in investing in the Fund is common to any
security -- the net asset value will fluctuate in response to changes in
economic conditions, interest rates and the market's perception of the
underlying portfolio securities held by the Fund.
 
    In pursuit of a Fund's investment objective, Wellington Management attempts
to select appropriate individual securities for inclusion in the Fund's
portfolio. In addition, Wellington Management attempts to successfully forecast
market trends and increase investments in the types of securities best suited to
take advantage of such trends. Thus, the investor is dependent on Wellington
Management's success not only in selecting individual securities, but also in
identifying the appropriate mix of securities consistent with the Fund's
investment objective.
 
   
    The services provided to the Fund by Hartford Life, HL Advisors, HIMCO,
Wellington Management and other service providers, depend on the smooth
functioning of their computer systems. Many computer software systems in use
today cannot distinguish the year 2000 from the year 1900 because of the way
dates are encoded and calculated. That failure could have a negative impact on
the handling of securities trades, pricing and account services. Hartford Life,
HL Advisors, HIMCO, Wellington Management and other service providers have been
actively working on necessary changes to their computer systems to deal with the
year 2000 issue and expect that their systems will be adapted in time for that
event.
    
 
                             INVESTMENT LIMITATIONS
 
    The Fund has adopted certain limitations in an attempt to reduce its
exposure to specific situations. Some of these limitations are that the Fund
will not:
 
(a) invest more than 25% of its assets in any one industry;
 
(b) borrow money, except from banks, and then only in amounts not exceeding
    33 1/3% of the value of the Fund's total assets (although for purposes of
    this restriction reverse repurchase agreements are not considered
    borrowings, as a non-fundamental operating policy, the Fund will limit
    combined borrowings and reverse repurchase transactions to 33 1/3% of the
    value of the Fund's total assets);
 
(c) with respect to 75% of the value of the Fund's total assets, purchase the
    securities of any issuer (other than cash, cash items or securities issued
    or guaranteed by the U.S. Government, its agencies, instrumentalities or
    authorities) if:
 
    (1) such purchase would cause more than 5% of the Fund's total assets taken
        at market value to be invested in the securities of such issuer; or
 
    (2) such purchase would at the time result in more than 10% of the
        outstanding voting securities of such issuer being held by the Fund.
 
    These investment restrictions are considered at the time investment
securities are purchased. The limitations described above, except as noted under
(b), and those listed under Fundamental Restrictions of the Funds in the SAI,
are considered fundamental and as such can only be changed with the approval of
a majority of the Fund's shareholders.
 
                             MANAGEMENT OF THE FUND
 
    The Fund's Board of Directors manages the business and affairs of the Fund
and takes action on all matters not reserved for the shareholders, including the
annual election of officers of the Fund who carry out all orders and resolutions
of the Board of Directors and carry out functions relating to the day to day
management of the affairs of the Fund.
 
                              MANAGEMENT SERVICES
 
    HL Advisors serves as investment manager to the Fund pursuant to a written
agreement entered into between HL Advisors and the Fund. Pursuant to such
agreement HL Advisors has overall investment supervisory responsibility for the
Fund. In addition, Hartford Life Insurance Company ("Hartford Life"), an
affiliate of HL Advisors, provides administrative personnel, services, equipment
and facilities and office space for proper operation of the Fund. HL Advisors
has contracted with Wellington Management for the provision of day to day
investment management services to the Fund. The Fund pays a fee to HL Advisors,
a portion of which may be used to compensate Wellington Management.
 
    For services rendered to the Fund, HL Advisors charges a monthly fee based
on the following annual rates as applied to the average of the calculated daily
net asset value of the Fund.

Advisors: Joseph H. Gareau is a Director and the President of HL Advisors;
Andrew W. Kohnke is a Managing Director and a Director of HL Advisors; and C.
Michael O'Halloran is a Director, Secretary and General Counsel of HL Advisors.
 
                   INVESTMENT SUB-ADVISORY AND OTHER SERVICES
 
    Wellington Management serves as sub-adviser to the Fund pursuant to a
written contract entered into between HL Advisors and Wellington Management.
 
    In connection with the services provided to the Funds, Wellington Management
makes all determinations with respect to the purchase and sale of portfolio
securities (subject to the terms and conditions of the investment objectives,
policies and restrictions of the Fund and to the general supervision of the
Fund's Boards of Directors and HL Advisors) and places, in the name of the Fund,
all orders for execution of the Fund's portfolio transactions. In conjunction
with such activities, Wellington Management regularly furnishes reports to the
Fund's Boards of Directors concerning economic forecasts, investment strategy,
portfolio activity and performance of the Fund.
 
    Wellington Management charges a quarterly fee to HL Advisors. The Fund does
not pay Wellington Management's fee nor any part thereof, nor does the Fund have
any obligation or responsibility to do so. Wellington Management's quarterly fee
is based upon the following annual rates as applied to the average of the
calculated daily net asset value of the Fund.

    Wellington Management has agreed to waive 100% of its sub-advisory fee until
shareholder assets (excluding assets contributed by HL Advisors or its
affiliates) reach $50 million.
 
    Wellington Management is a professional investment counseling firm which
provides investment services to investment companies, employee benefit plans,
endowments, foundations and other institutions and individuals. Wellington
Management and its predecessor organizations have provided investment advisory
services since 1928. As of December 31, 1997, Wellington Management held
discretionary management authority with respect to approximately $175 billion of
client assets. Wellington Management, 75 State Street, Boston, MA 02109, is a
Massachusetts limited liability partnership, of which the following persons are
managing partners: Robert W. Doran, Duncan M. McFarland and John R. Ryan.
 
                               PORTFOLIO MANAGER
 
    James A. Rullo, CFA and Vice President of Wellington Management, serves as
portfolio manager to the Fund. Prior to joining Wellington Management in 1994 as
a quantitative analyst and portfolio manager, Mr. Rullo was a portfolio manager
with PanAgora Asset Management from 1991 to 1994 and prior to that with The
Boston Company from 1987.
 
                               PORTFOLIO TURNOVER
 
    The Fund may sell a portfolio investment soon after its acquisition if
Wellington Management believes that such a disposition is in the Fund's best
interest. A high rate of portfolio turnover involves correspondingly greater
brokerage commission expenses and other transaction costs, which must be
ultimately borne by a Fund's shareholders. High portfolio turnover may result in
the realization of substantial capital gains; distributions derived from such
gains may be treated as ordinary income for Federal income tax purposes.
Although it is not possible to predict future portfolio turnover rates
accurately, and such rates may vary from year to year, it is anticipated that
the Fund's portfolio turnover rate will not exceed 100%.
 
                             BROKERAGE COMMISSIONS
 
    Although the Rules of Fair Practice of the National Association of
Securities Dealers, Inc. prohibit its members from seeking orders for the
execution of investment company portfolio transactions on the basis of their
sales of investment company shares, under such rules, sales of investment
company shares may be considered in selecting brokers to effect portfolio
transactions. Accordingly, some portfolio transactions are, subject to such
Rules and to obtaining best prices and executions, effected through dealers who
sell shares of the Fund. Wellington Management may also select an affiliated
broker-dealer to execute transactions for the Fund, provided that the
commissions, fees or other remuneration paid to such affiliated broker are
reasonable and fair as compared to that paid to non-affiliated brokers for
comparable transactions.

                            ADMINISTRATIVE SERVICES
                                  FOR THE FUND
 
    An Administrative Services Agreement between the Fund and Hartford Life
provides that Hartford Life will manage the business affairs and provide
administrative services to the Fund. Under the terms of this Agreement, Hartford
Life will provide the following: administrative personnel, services, equipment
and facilities and office space for proper operation of the Fund. Hartford Life
has also agreed to arrange for the provision of additional services necessary
for the proper operation of the Fund, although the Fund pays for these services
directly. See "Expenses of the Fund." As compensation for the services to be
performed by Hartford Life, the Fund pays to Hartford Life, as promptly as
possible after the last day of each month, a monthly fee equal to the annual
rate of .175% of the average daily net assets of the Fund.
 
                              EXPENSES OF THE FUND
 
   
    The Fund assumes and pays the following costs and expenses: interest; taxes;
brokerage charges (which may be to affiliated broker-dealers); costs of
preparing, printing and filing any amendments or supplements to the registration
forms of the Fund and its securities; all federal and state registration,
qualification and filing costs and fees, (except the initial costs and fees,
which will be borne by Hartford Life), issuance and redemption expenses,
transfer agency and dividend and distribution disbursing agency costs and
expenses; custodian fees and expenses; accounting, auditing and legal expenses;
fidelity bond and other insurance premiums; fees and salaries of directors,
officers and employees of the Fund other than those who are also officers of
Hartford Life or its affiliates; industry membership dues; all annual and
semiannual reports and prospectuses mailed to the Fund's shareholders as well as
all quarterly, annual and any other periodic report required to be filed with
the SEC or with any state; any notices required by a federal or state regulatory
authority, and any proxy solicitation materials directed to the Fund's
shareholders as well as all printing, mailing and tabulation costs incurred in
connection therewith, and any expenses incurred in connection with the holding
of meetings of the Fund's shareholders and other miscellaneous expenses related
directly to the Fund's operations and interest. As discussed in greater detail
below, under "Sale and Redemption of Shares", the Class IB shares may pay for
certain distribution related expenses in connection with activities primarily
intended to result in the sale of Class IB shares.
    
 
                        PERFORMANCE RELATED INFORMATION
 
    The Fund may advertise certain performance related information. Performance
information about the Fund is based on the Fund's past performance only and is
no indication of future performance.
 
    The Fund may include its total return in advertisements or other sales
material. When the Fund advertises its total return, it will usually be
calculated for one year, five years, and ten years or some other relevant
periods if the Fund has not been in existence for at least ten years. Total
return is measured by comparing the value of an investment in the Fund at the
beginning of the relevant period to the value of the investment at the end of
the period (assuming immediate reinvestment of any dividends or capital gains
distributions).
 
                                   DIVIDENDS
 
    The shareholders of the Fund shall be entitled to receive such dividends as
may be declared by the Fund's Board of Directors, from time to time based upon
the investment performance of the assets making up the Fund's portfolio. The
policy with respect to the Fund is to pay dividends from net investment income
and to make distributions of realized capital gains, if any, at least once each
year.
 
    Such dividends and distributions will be automatically invested in
additional full or fractional shares monthly on the last business day of each
month at the per share net asset value on that date. Provision is also made to
pay such dividends and distributions in cash if requested. Such dividends and
distributions will be in cash or in full or fractional shares of the Fund at net
asset value.
 
                                DETERMINATION OF
                                NET ASSET VALUE
 
    The net asset value per share is determined for the Fund as of the close of
the NYSE (normally 4:00 p.m. Eastern Time) on each regular business day (as
previously defined) by dividing the value of the Fund's net assets by the number
of shares outstanding. The assets of the Fund are valued primarily on the basis
of market quotations. If quotations are not readily available, assets are valued
by a method that the Board of Directors believes accurately reflects fair value.
Foreign securities are valued on the basis of quotations from the primary market
in which they are traded, and are translated from the local currency into U.S.
dollars using current exchange rates. With respect to the Fund, short-term
investments that will mature in 60 days or less are also valued at amortized
cost, which approximates market value.

- --------------------------------------------------------------------------------
 
                            PURCHASE OF FUND SHARES
 
    Fund shares are made available to serve as the underlying investment vehicle
for variable annuity and variable life insurance separate accounts of The
Hartford Life Insurance Companies. Shares of the Fund are sold by Hartford
Securities Distribution Company, Inc. (the "Distributor") on a no-load basis at
their net asset values. See "Determination of Net Asset Value" and "Sale and
Redemption of Shares."
 
    It is conceivable that in the future it may be disadvantageous for variable
annuity separate accounts and variable life insurance separate accounts to
invest in the Funds simultaneously. Although The Hartford Life Insurance
Companies and the Funds do not currently foresee any such disadvantages either
to variable annuity contract owners or variable life insurance policy owners,
each Fund's Board of Directors intends to monitor events in order to identify
any material conflicts between such contract owners and policy owners and to
determine what action, if any, should be taken in response thereto. If the Board
of Directors of a Fund were to conclude that separate funds should be
established for variable life and variable annuity separate accounts, the
variable life and variable annuity contract holders would not bear any expenses
attendant to the establishment of such separate funds.
 
    The Fund offers investors two different classes of shares -- Class IA and
Class IB. Class IB shares are offered by this Prospectus. Class IA shares are
offered by a separate prospectus in connection with other variable insurance
products. The different classes of shares represent investments in the same
portfolio of securities but are subject to different expenses and will likely
have different share prices.
 
                              SALE AND REDEMPTION
                                   OF SHARES
 
    The shares of the Fund are sold and redeemed by the Fund at their net asset
value next determined after receipt of a purchase or redemption order in good
order in writing at the Fund's home office, P.O. Box 2999, Hartford, CT
06104-2999. The value of shares redeemed may be more or less than original cost,
depending upon the market value of the portfolio securities at the time of
redemption. Payment for shares redeemed will be made within seven days after the
redemption request is received in proper form by the Fund. However, the right to
redeem Fund shares may be suspended or payment therefor postponed for any period
during which: (1) trading on the NYSE is closed for other than weekends and
holidays; (2) an emergency exists, as determined by the SEC, as a result of
which (a) disposal by the Fund of securities owned by it is not reasonably
practicable, or (b) it is not reasonably practicable for the Fund to determine
fairly the value of its net assets; or (3) the SEC by order so permits for the
protection of stockholders of the Fund.
 
    The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 under the
1940 Act for the Class IB shares. Pursuant to the Distribution Plan, the Fund
compensates the Distributor from assets attributable to the Class IB shares for
services rendered and expenses borne in connection with activities primarily
intended to result in the sale of the Class IB shares. It is anticipated that a
portion of the amounts received by the Distributor will be used to defray
various costs incurred or paid by the Distributor in connection with the
printing and mailing of Fund prospectuses, statements of additional information,
any supplements thereto and shareholder reports and holding seminars and sales
meetings with wholesale and retail sales personnel designed to promote the
distribution of Class IB shares. The Distributor may also use a portion of the
amounts received to provide compensation to financial intermediaries and
third-party broker-dealers for their services in connection with the
distribution of Class IB shares.
 
    Although the Distribution Plan provides that the Fund may pay annually up to
0.25% of the average daily net assets of the Fund attributable to its Class IB
shares for activities primarily intended to result in the sale of Class IB
shares, the Distributor has voluntarily agreed to waive .07% of the fee. This
waiver may be withdrawn at any time after notice to shareholders. Under the
terms of the Distribution Plan and the principal underwriting agreement, the
Fund is authorized to make payments monthly to the Distributor which may be used
to pay or reimburse entities providing distribution and shareholder servicing
with respect to the Class IB shares for such entities' fees or expenses incurred
or paid in that regard.
 
    The Distribution Plan is of a type known as a "compensation" plan because
payments are made for services rendered to the Fund with respect to Class IB
shares regardless of the level of expenditures by the Distributor. The Directors
will, however, take into account such expenditures for purposes of reviewing
operations under the Distribution Plan and in connection with their annual
consideration of the Plan's renewal. The Distributor has indicated that it
expects its expenditures to include, without limitation: (a) the printing and
mailing of Fund prospectuses, statements of additional information, any
supplements thereto and shareholder reports for prospective contract owners of
variable insurance products with respect to the Class IB shares of the Fund; (b)
those relating to the development, preparation, printing and mailing of
advertisements, sales literature and other promotional materials describing and/
or relating to the Class IB shares of the Fund; (c) holding seminars and sales
meetings designed to promote the distribution of Fund Class IB shares; (d)
obtaining information and providing explanations to wholesale and retail
distributors of contracts regarding Fund investment objectives and policies and
other information about the Fund, including the performance of the Fund; (e)
training sales personnel regarding the Class IB shares of the Fund; and (f)
financing

any other activity that the Distributor determines is primarily intended to
result in the sale of Class IB shares.
 
                              FEDERAL INCOME TAXES
 
    The Fund has elected and intends to qualify under Subchapter M of the Code.
The Fund intends to distribute all of its net income and gains to shareholders.
Such distributions are taxable income and capital gains. The Fund will inform
shareholders of the amount and nature of such income and gains. The Fund may be
subject to a 4% nondeductible excise tax as well as an income tax measured with
respect to certain undistributed amounts of income and capital gain. The Fund
expects to make such additional distributions of net investment income as are
necessary to avoid the application of these taxes. For a discussion of the tax
implications of a purchase or sale of the Fund's shares by the insurer,
reference should be made to the section entitled "Federal Tax Considerations" in
the appropriate separate account prospectus.
 
    If eligible, the Fund may make an election to pass through to its
shareholders, The Hartford Life Insurance Companies, a credit for any foreign
taxes paid during the year. If such election is made, the pass-through of the
foreign tax credit will result in additional taxable income and income tax to
The Hartford Life Insurance Companies. The amount of additional tax may be more
than offset by the foreign tax credits which are passed through. These foreign
tax credits may provide a benefit to The Hartford Life Insurance Companies.
 
                    OWNERSHIP AND CAPITALIZATION OF THE FUND
 
                                 CAPITAL STOCK
 
    As of the date of this prospectus, the authorized capital stock of the Fund
consists of 3 billion shares at a par value of $.001 per share.
 
    The Board of Directors is authorized, without further shareholder approval,
to authorize additional shares and to classify and reclassify the Fund into one
or more classes. Accordingly, the Directors have authorized the issuance of two
classes of shares of the Fund designated as Class IA and Class IB shares. The
shares of each class represent an interest in the same portfolio of investments
of the Fund and have equal rights as to voting, redemption, and liquidation.
However, each class bears different expenses and therefore the net asset values
of the two classes and any dividends declared may differ between the two
classes.
 
                                     VOTING
 
    Under the Fund's multi-class system, shares of each class of the Fund
represent an equal pro rata interest in the Fund and, generally, shall have
identical voting, dividend, liquidation, and other rights, preferences, powers,
restrictions, limitations, qualifications and terms and conditions, except that:
(a) each class shall have a different designation; (b) each class of shares
shall bear its "Class Expenses;" (c) each class shall have exclusive voting
rights on any matter submitted to shareholders that relates solely to its
distribution arrangements; (d) each class shall have separate voting rights on
any matter submitted to shareholders in which the interests of one class differ
from the interests of any other class; (e) each class may have separate exchange
privileges, although exchange privileges are not currently contemplated; and (f)
each class may have different conversion features, although a conversion feature
is not currently contemplated. Expenses currently designated as "Class Expenses"
by the Fund's Board of Directors under the plan pursuant to Rule 18f-3 are
currently limited to payments made to the Distributor for the Class IB shares,
pursuant to the Distribution Plan for the Class IB shares adopted pursuant to
Rule 12b-1 under the 1940 Act. Each shareholder shall be entitled to one vote
for each share of the Fund held upon all matters submitted to the shareholders
generally. Class specific issues, such as a modification to a Rule 12b-1 plan
that could materially increase fees, will be voted on only by the affected
class. With respect to the Fund's shares issued as described above under
"Purchase of Fund Shares," as well as Fund shares which are not otherwise
attributable to variable annuity contract owners or variable life policy
holders, The Hartford Life Insurance Companies shall be the shareholders of
record. Each of The Hartford Life Insurance Companies will vote all Fund shares,
pro rata, according to the written instructions of the contract owners of the
variable annuity contracts and the policy holders of the variable life contracts
issued by it using the Fund as investment vehicles. This position is consistent
with the policy of the SEC staff.
 
                                  OTHER RIGHTS
 
    Each share of Fund stock, when issued and paid for in accordance with the
terms of the offering, will be fully paid and non-assessable. Shares of Fund
stock have no pre-emptive, subscription or conversion rights and are redeemable
as set forth under "Sale and Redemption of Shares." Upon liquidation of the
Fund, the shareholders of the Fund shall be entitled to share, pro rata, in any
assets of the Fund after discharge of all liabilities and payment of the
expenses of liquidation.

                                   APPENDIX A
 
    The rating information which follows describes how the rating services
mentioned presently rate the described securities. No reliance is made upon the
rating firms as "experts" as that term is defined for securities purposes.
Rather, reliance on this information is on the basis that such ratings have
become generally accepted in the investment business.
 
                                RATING OF BONDS
 
    MOODY'S INVESTORS SERVICE, INC. ("MOODY'S")
 
    Aaa -- Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edge." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.
 
    Aa -- Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long term risks appear somewhat larger than in Aaa securities.
 
    A -- Bonds which are rated A possess many favorable investment attributes
and are to be considered as upper medium grade obligations. Factors giving
security to principal and interest are considered adequate but elements may be
present which suggest a susceptibility to impairment sometime in the future.
 
    Baa -- Bonds which are rated Baa are considered as medium grade obligations,
i.e., they are neither highly protected nor poorly secured. Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.
 
    Ba -- Bonds which are rated Ba are judged to have speculative elements;
their future cannot be considered as well assured. Often the protection of
interest and principal payments may be very moderate and thereby not well
safeguarded during both good and bad times over the future. Uncertainty of
position characterizes bonds in this class.
 
    B -- Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.
 
    Caa -- Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.
 
    Ca -- Bonds which are rated Ca represent obligations which are speculative
in a high degree. Such issues are often in default or have other marked
shortcomings.
 
    C -- Bonds which are rated C are the lowest rated class of bonds and issues
so rated can be regarded as having extremely poor prospects of ever earning any
real investment standing.
 
    STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
    AAA -- Bonds rated AAA are the highest grade obligations. Capacity to pay
interest and repay principal is extremely strong.
 
    AA -- Bonds rated AA have a very strong capacity to pay interest and repay
principal and differ from AAA issues only in small degree.
 
    A -- Bonds rated A have a very strong capacity to pay interest and repay
principal although they are somewhat more susceptible to the considerable
investment strength but are not entirely free from adverse effects of changes in
circumstances and economic conditions than debt in the highest rated categories.
 
    BBB -- Bonds rated BBB and regarded as having an adequate capacity to pay
interest and repay principal. Whereas they normally exhibit adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category then in higher rated categories.
 
    BB, B, CCC, CC, C -- Debt rated BB, B, CCC, CC, and C is regarded, on
balance, as predominantly speculative with respect to the issuer's capacity to
pay interest and repay principal in accordance with the terms of the obligation.
While such debt will likely have some quality and protective characteristics,
these are outweighed by large uncertainties or major risk exposures to adverse
conditions.
 
                           RATING OF COMMERCIAL PAPER
 
    Purchases of corporate debt securities used for short-term investment,
generally called commercial paper, will be limited to the top two grades of
Moody's, Standard & Poor's, Duff & Phelps, Fitch Investor Services and Thomson
Bank Watch or other NRSROs (nationally recognized statistical

rating organizations) rating services and will be an eligible security under
Rule 2a-7.
 
    MOODY'S
 
    Issuers rated Prime-1 (or related supporting institutions) have a superior
capacity for repayment of short-term promissory obligations. Prime-1 repayment
capacity will normally be evidenced by the following characteristics:
 
- - Leading market positions in well-established industries.
 
- - High rates of return on funds employed.
 
- - Conservative capitalization structures with moderate reliance on debt and
  ample asset protection.
 
- - Broad margins in earnings coverage of fixed financial charges and high
  internal cash generation.
 
- - Well-established access to a range of financial markets and assured sources of
  alternate liquidity.
 
    Issuers rated Prime-2 (or related supporting institutions) have a strong
capacity for repayment of short-term promissory obligations. This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, will be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.
 
    Issuers rated Prime-3 (or related supporting institutions) have an
acceptable capacity for repayment of short-term promissory obligations. The
effect of industry characteristics and market composition may be more
pronounced. Variability in earnings and profitability may result in changes in
the level of debt protection measurements and the requirement for relatively
high financial leverage. Adequate alternate liquidity is maintained.
 
    Issuers rated Not Prime do not fall within any of the Prime rating
categories.
 
    STANDARD & POOR'S
 
    The relative strength or weakness of the following factors determines
whether the issuer's commercial paper is rated A-1 or A-2.
 
- - Liquidity ratios are adequate to meet cash requirements.
 
    Liquidity ratios are basically as follows, broken down by the type of
issuer:
 
    Industrial Company: acid test ratio, cash flow as a percent of current
liabilities, short-term debt as a percent of current liabilities, short-term
debt as a percent of current assets.
 
    Utility: current liabilities as a percent of revenues, cash flow as a
percent of current liabilities, short-term debt as a percent of capitalization.
 
    Finance Company: current ratio, current liabilities as a percent of net
receivables, current liabilities as a percent of total liabilities.
 
- - The long-term senior debt rating is "A" or better; in some instances "BBB"
  credits may be allowed if other factors outweigh the "BBB".
 
- - The issuer has access to at least two additional channels of borrowing.
 
- - Basic earnings and cash flow have an upward trend with allowances made for
  unusual circumstances.
 
- - Typically, the issuer's industry is well established and the issuer has a
  strong position within its industry.
 
- - The reliability and quality of management are unquestioned.

                                GENERAL INFORMATION
                                          
  The Hartford Growth and Income HLS Fund (the "Fund") is a separate series 
of Hartford Series Fund, Inc. (the "Company"), an open-end management 
investment company.  The Fund is one of thirteen affiliated diversified 
portfolios used as funding media for certain variable annuity and variable 
life insurance separate accounts of Hartford Life Insurance Company and 
Hartford Life and Annuity Insurance Company (collectively, "The Hartford Life 
Insurance Companies").  This SAI relates only to the Hartford Growth and 
Income HLS Fund.  HL Investment Advisors, Inc. ("HL Advisors") is the 
investment manager to the Fund.  HL Advisors is an indirect majority owned 
subsidiary of The Hartford Financial Services Group, Inc., ("The Hartford") 
an insurance holding company with over $100 billion in assets.  In addition, 
Wellington Management Company, LLP ("Wellington Management") is sub-adviser 
to the Fund.

                          INVESTMENT OBJECTIVE AND POLICIES

A.   FUNDAMENTAL RESTRICTIONS OF THE FUND

  The Fund has adopted the following fundamental investment restrictions 
which may not be changed without approval of a majority of the Fund's 
outstanding voting securities.  Under the Investment Company Act of 1940 (the 
"1940 Act"), and as used in the Prospectus and this SAI, a "majority of the 
outstanding voting securities" means the approval of the lesser of (1) the 
holders of 67% or more of the shares of the Fund represented at a meeting if 
the holders of more than 50% of the outstanding shares of the Fund are 
present in person or by proxy or (2) the holders of more than 50% of the 
outstanding shares of the Fund.

  The investment objective, investment style and certain investment policies 
of the Fund are set forth in the Prospectus.  Set forth below are the 
fundamental investment policies applicable to the Fund followed by the 
non-fundamental policies applicable to the Fund.

  The Fund may not:

  1. Issue senior securities.  For purposes of this restriction, the issuance 
of shares of common stock in multiple classes or series, obtaining of 
short-term credits as may be necessary for the clearance of purchases and 
sales of portfolio securities, short sales against the box, and the following 
practices when a segregated account has been established to cover such 
transactions or when an offsetting position has been established by the Fund 
are not deemed to be issuances of senior securities: the purchase or sale of 
permissible options and futures transactions (and the use of initial and 
maintenance margin arrangements with respect to futures contracts or related 
options transactions), the purchase or sale of securities on a when issued or 
delayed delivery basis, permissible borrowings entered into in accordance 
with the Fund's investment policies, and reverse repurchase agreements and 
mortgage dollar rolls.

                                      -1-


<PAGE>


  2. Borrow money, except from banks and then only if immediately after each 
such borrowing there is asset coverage of at least 300% as defined in the 
1940 Act. Although reverse repurchase agreements, mortgage dollar rolls, 
short sales against the box, futures contracts, options on futures contracts, 
securities or indices, when issued and delayed delivery transactions and 
securities lending are not subject to this restriction, in most cases a 
segregated account will be set up to cover such transactions.

  3. Act as an underwriter for securities of other issuers.

  4. Purchase or sell real estate, except that the Fund may (i) acquire or 
lease office space for its own use, (ii) invest in securities of issuers that 
invest in real estate or interests therein, (e.g. real estate investment 
trusts) (iii) invest in securities that are secured by real estate or 
interests therein, (iv) purchase and sell mortgage-related securities, (v) 
hold and sell real estate acquired by the Fund as a result of the ownership 
of securities and (vi) invest in real estate limited partnerships. 

  5. Invest in commodities, except that the Fund may (i) invest in securities 
of issuers that invest in commodities, and (ii) engage in permissible options 
and futures transactions and forward foreign currency contracts, entered into 
in accordance with the Fund's investment policies.

  6. Make loans, except that the Fund (i) may lend portfolio securities in 
accordance with the Fund's investment policies in amounts up to 33-1/3% of 
the Fund's total assets taken at market value, (ii) enter into fully 
collateralized repurchase agreements, and (iii) purchase debt obligations in 
which the Fund may invest consistent with its investment policies.

  7. Purchase the securities of issuers conducting their principal activity 
in the same industry if, immediately after such purchase, the value of its 
investments in such industry would exceed 25% of its total assets taken at 
market value at the time of such investment.  This limitation does not apply 
to investments in obligations issued or guaranteed by the U.S. Government or 
any of its agencies, instrumentalities or authorities.

  In addition, the Fund will operate as a "diversified" fund within the 
meaning of the 1940 Act.  This means that with respect to 75% of the Fund's 
total assets, the Fund will not purchase securities of an issuer (other than 
cash, cash items or securities issued or guaranteed by the U.S. Government, 
its agencies, instrumentalities or authorities), if

  (a)     such purchase would cause more than 5% of the Fund's total assets   
          taken at market value to be invested in the securities of such 
          issuer; or

  (b)     such purchase would at the time result in more than 10% of the 
          outstanding voting securities of such issuer being held by the Fund.

   If a percentage restriction on investment or utilization of assets as set
forth above is adhered to at the time an investment is made, a later change in
percentage resulting from changes in the

                                      -2-


<PAGE>


values of the Fund's assets will not be considered a violation of the 
restriction; provided, however, that the asset coverage requirement 
applicable to borrowings under Section 18(f)(1) of the 1940 Act shall be 
maintained in the manner contemplated by that Section.

  In order to permit the sale of shares of the Fund in certain states, the 
Board of Directors may, in its sole discretion, adopt restrictions or 
investment policies more restrictive than those described above.  Should the 
Board of Directors determine that any such more restrictive policy is no 
longer in the best interest of the Fund and its shareholders, the Fund may 
cease offering shares in the state involved and the Board of Directors may 
revoke such restrictive policy.  Moreover, if the states involved shall no 
longer require any such restrictive policy, the Board of Directors may, in 
its sole discretion, revoke such policy.

B.  NON-FUNDAMENTAL INVESTMENT RESTRICTIONS OF THE FUND.

  The following restrictions are designated as non-fundamental and may be
changed by the Board of Directors without the approval of shareholders.

  The Fund may not:

  1. Purchase securities on margin or make short sales of securities,
except that the Fund may obtain such short-term credit as may be necessary for
the clearance of purchases and sales of  securities and except for transactions
in futures contracts and options thereon.

  2. Purchase securities which are illiquid if, as a result of such
purchase, more than 15% of its net assets would consist of such securities.

  3. Alone or together with any other of the Hartford Mutual Funds, make
investments for the purpose of exercising control over or management of any
issuer.

  4. Mortgage, pledge, hypothecate, or in any manner transfer, as security
for indebtedness, any securities owned or held by it, except to secure reverse
repurchase agreements; however, for purposes of this restriction, collateral
arrangements with respect to transactions in futures contracts and options
thereon are not deemed to be a pledge of securities.

  5. Invest more than 5% of its assets in securities of other investment
companies and will not acquire more than 3% of the total outstanding voting
securities of any one investment company. 

  6. Purchase additional securities when money borrowed exceeds 5% of the
Fund's total assets.

  7.  Borrow money, engage in reverse repurchase agreements or engage in
activities which are the economic equivalent of borrowing if the combination of
such activities exceeds 33-1/3% of the Fund's total assets.

                                      -3-


<PAGE>


  If a percentage restriction on investment or utilization of assets as set
forth above is adhered to at the time an investment is made, a later change in
percentage resulting from changes in the values of the Fund's assets will not be
considered a violation of the restriction.

  U.S. TREASURY DEPARTMENT DIVERSIFICATION REGULATIONS. The U.S. Treasury 
Department has issued diversification regulations under Section 817 of the 
Internal Revenue Code. If a mutual fund underlying a variable contract, other 
than a pension plan contract, is not adequately diversified within the terms 
of these regulations, the contract owner will have adverse income tax 
consequences. These regulations provide, among other things, that a mutual 
fund shall be considered adequately diversified if (i) no more than 55% of 
the value of the assets in the fund is represented by any one investment; 
(ii) no more than 70% of the value of the assets in the fund is represented 
by any two investments; (iii) no more than 80% of the value of the assets in 
the fund is represented by any three investments and (iv) no more than 90% of 
the value of the total assets of the fund is represented by any four 
investments. In determining whether the diversification standards are met, 
each United States Government Agency or instrumentality shall be treated as a 
separate issuer.

MISCELLANEOUS INVESTMENT PRACTICES

  A further description of certain of the policies described in the
Prospectus is set forth below.

MONEY MARKET INSTRUMENTS AND TEMPORARY INVESTMENT STRATEGIES

  The Fund may hold cash or cash equivalents and invest in high quality money
market instruments under appropriate circumstances as determined by Wellington
Management.  The Fund may invest up to 100% of its assets in cash, cash
equivalents or money market instruments only for temporary defensive purposes.

  Money market instruments include:  (1) banker's acceptances; (2)
obligations of governments (whether U.S. or non-U.S.) and their agencies and
instrumentalities; (3) short-term corporate obligations, including commercial
paper, notes, and bonds; (4) other short-term debt obligations; (5) obligations
of U.S. banks, non-U.S. branches of U.S. banks (Eurodollars), U.S. branches and
agencies of non-U.S. banks (Yankee dollars), and non-U.S. branches of non-U.S.
banks; (6) asset-backed securities; and (7) repurchase agreements.
 
REPURCHASE AGREEMENTS
 
  The Fund is permitted to enter into fully collateralized repurchase
agreements.  The Fund's Board of Directors has established standards for
evaluation of the creditworthiness of the banks and securities dealers with
which the Funds will engage in repurchase agreements and monitors on a quarterly
basis Wellington Management's compliance with such standards.  Presently, the
Fund may

                                      -4-

<PAGE>


enter into repurchase agreements only with commercial banks with at least $1 
billion in assets or with recognized government securities dealers with a 
minimum net capital of $100 million.

  Wellington Management will monitor such transactions to ensure that the 
value of underlying collateral will be at least equal at all times to the 
total amount of the repurchase obligation, including the accrued interest.  
If the seller defaults, the Fund could realize a loss on the sale of the 
underlying security to the extent that the proceeds of sale including accrued 
interest are less than the resale price provided in the agreement including 
interest.  

  A repurchase agreement is an agreement by which the seller of a security 
agrees to repurchase the security sold at a mutually agreed upon time and 
price. It may also be viewed as the loan of money by the Fund to the seller. 
The resale price would be in excess of the purchase price, reflecting an 
agreed upon market interest rate. 

REVERSE REPURCHASE AGREEMENTS

  The Fund may also enter into reverse repurchase agreements.  Reverse 
repurchase agreements involve sales by the Fund of portfolio assets 
concurrently with an agreement by the Fund to repurchase the same assets at a 
later date at a fixed price.  Reverse repurchase agreements carry the risk 
that the market value of the securities which the Fund is obligated to 
repurchase may decline below the repurchase price.  A reverse repurchase 
agreement is viewed as a collateralized borrowing by the Fund.  Borrowing 
magnifies the potential for gain or loss on the portfolio securities of the 
Fund and, therefore, increases the possibility of fluctuation in the Fund's 
net asset value. The Fund will establish a segregated account with the Fund's 
custodian bank in which the Fund will maintain liquid assets equal in value 
to the Fund's obligations in respect of reverse repurchase agreements.  The 
Fund will not enter into reverse repurchase transactions if the combination 
of all borrowings from banks and the value of all reverse repurchase 
agreements for the Fund equals more than 33-1/3% of the value the Fund's 
total assets.

DEBT SECURITIES

  The Fund is permitted to invest in debt securities including:  (1) 
securities issued or guaranteed as to principal or interest by the U.S. 
Government, its agencies or instrumentalities; (2) non-convertible debt 
securities issued or guaranteed by U.S. corporations or other issuers 
(including foreign governments or corporations); and (3) securities issued or 
guaranteed as to principal or interest by a sovereign government or one of 
its agencies or political subdivisions, supranational entities such as 
development banks, non-U.S. corporations, banks or bank holding companies, or 
other non-U.S. issuers.

INVESTMENT GRADE DEBT SECURITIES

  The Fund is permitted to invest in debt securities rated within the four 
highest rating categories (i.e., Aaa, Aa, A or Baa by Moody's or AAA, AA, A 
or BBB by S&P) (or, if unrated,

                                      -5-

<PAGE>

securities of comparable quality as determined by Wellington Management).  
These securities are generally referred to as "investment grade securities."  
Each rating category has within it different gradations or sub-categories.  
If the Fund is authorized to invest in a certain rating category, the Fund is 
also permitted to invest in any of the sub-categories or gradations within 
that rating category.  If a security is downgraded to a rating category which 
does not qualify for investment, Wellington Management will use its 
discretion on whether to hold or sell based upon its opinion on the best 
method to maximize value for shareholders over the long term.  Debt 
securities carrying the fourth highest rating (i.e., "Baa" by Moody's and 
"BBB" by S&P), and unrated securities of comparable quality (as determined by 
Wellington Management) are viewed to have adequate capacity  for payment of 
principal and interest,  but do involve a higher degree of risk than that 
associated with  investments in debt securities in the higher rating 
categories and such securities lack outstanding investment characteristics 
and do have speculative characteristics.

HIGH YIELD-HIGH RISK SECURITIES

  The Fund may invest up to 5% of its assets in high yield debt securities 
(i.e., rated as low as "C" by Moody's or S&P, and unrated securities of 
comparable quality as determined by Wellington Management).  Securities rated 
below investment grade are commonly referred to as "high yield-high risk 
securities" or "junk bonds". Each rating category has within it different 
gradations or sub-categories. For instance the "Ba" rating for Moody's 
includes "Ba3", "Ba2" and "Ba1". Likewise the S&P rating category of "BB" 
includes "BB+", "BB" and "BB-". If the Fund is authorized to invest in a 
certain rating category, the Fund is also permitted to invest in any of the 
sub-categories or gradations within that rating category. Securities in the 
highest category below investment grade are considered to be of poor standing 
and predominantly speculative.  These securities are considered speculative 
with respect to the issuer's capacity to pay interest and repay principal in 
accordance with the terms of the obligations. Accordingly, it is possible 
that these types of factors could, in certain instances, reduce the value of 
securities held by the Fund with a commensurate effect on the value of the 
Fund's shares. If a security is downgraded to a rating category which does 
not qualify for investment, Wellington Management will use its discretion on 
whether to hold or sell based upon its opinion on the best method to maximize 
value for shareholders over the long term.

EQUITY SECURITIES

  The Fund may invest in equity securities which include common stocks, 
preferred stocks (including convertible preferred stock) and rights to 
acquire such securities.  In addition, the Fund may invest in securities such 
as bonds, debentures and corporate notes which are convertible into common 
stock at the option of the holder.

SMALL CAPITALIZATION SECURITIES

                                      -6-

<PAGE>

  The Fund may invest in equity securities (including securities issued in 
initial public offerings) of companies which have less than $2 billion in 
market capitalization ("Small Capitalization Securities"). Because the 
issuers of Small Capitalization Securities tend to be smaller or less 
well-established companies, they may have limited product lines, market share 
or financial resources and may have less historical data with respect to 
operations and management.  As a result, Small Capitalization Securities are 
often less marketable and experience a higher level of price volatility than 
securities of larger or more well-established companies. In addition, 
companies whose securities are offered in initial public offerings may be 
more dependent on a limited number of key employees. Because securities 
issued in initial public offerings are being offered to the public for the 
first time, the market for such securities may be inefficient and less liquid.

NON-U.S. SECURITIES 

  The Fund is permitted to invest a portion of its assets in non-U.S. 
securities, including, in the case of permitted equity investments, American 
Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs").  ADRs 
are certificates issued by a U.S. bank or trust company and represent the 
right to receive securities of a non-U.S. issuer deposited in a domestic bank 
or non-U.S. branch of a U.S. bank. ADRs are traded on a U.S. securities 
exchange, or in an over-the-counter market, and are denominated in U.S. 
dollars.  GDRs are certificates issued globally and evidence a similar 
ownership arrangement. GDRs are traded on non-U.S. securities exchanges and 
are denominated in non-U.S. currencies. The value of an ADR or a GDR will 
fluctuate with the value of the underlying security, will reflect any changes 
in exchange rates and otherwise will involve risks associated with investing 
in non-U.S. securities. When selecting securities of non-U.S. issuers, 
Wellington Management will evaluate the economic  and political climate and 
the principal securities markets of the country in which an issuer is located.

  Investing in securities issued by non-U.S. companies involves 
considerations and potential risks not typically associated with investing in 
obligations issued by U.S. companies. Less information may be available about 
non-U.S. companies than about U.S. companies and non-U.S. companies generally 
are not subject to uniform accounting, auditing and financial reporting 
standards or to other regulatory practices and requirements comparable to 
those applicable to U.S. companies. The values of non-U.S. securities are 
affected by changes in currency rates or exchange control regulations, 
restrictions or prohibition on the repatriation of non-U.S. currencies, 
application of non-U.S. tax laws, including withholding taxes, changes in 
governmental administration or economic or monetary policy (in the U.S. or 
outside the U.S.) or changed circumstances in dealings between nations. Costs 
are also incurred in connection with conversions between various currencies.

  Investing in non-U.S. sovereign debt will expose a Fund to the direct or 
indirect consequences of political, social or economic changes in the 
developing and emerging countries that issue the securities. The ability and 
willingness of sovereign obligers in developing and emerging countries or the 
governmental authorities that control repayment of their external debt to pay 
principal and interest on such debt when due may depend on general economic 
and political conditions within the relevant country. Countries such as those 
in which the Fund may invest have

                                      -7-

<PAGE>

historically experienced, and may continue to experience, high rates of 
inflation, high interest rates, exchange rate trade difficulties and 
unemployment. Some of these countries are also characterized by political 
uncertainty or instability. Additional factors which may influence the 
ability or willingness to service debt include, but are not limited to, a 
country's cash flow situation, the availability of sufficient foreign 
exchange on the date a payment is due, the relative size of its debt service 
burden to the economy as a whole, and its government's policy towards the 
IMF, the World Bank and other international agencies.

  From time to time the Fund may invest up to 25% of its assets in companies 
located in emerging countries. Compared to the United States and other 
developed countries, developing countries may have relatively unstable 
governments, economies based on only a few industries, and securities markets 
that are less liquid and trade a small number of securities. Prices on these 
exchanges tend to be volatile and, in the past, securities in these countries 
have offered greater potential for gain (as well as loss) than securities of 
companies located in developed countries.

CURRENCY TRANSACTIONS
 
  The Fund may engage in currency transactions to hedge the value of 
portfolio securities denominated in particular currencies against 
fluctuations in relative value. Currency transactions include forward 
currency contracts, currency swaps, exchange-listed and over-the-counter  
("OTC") currency futures contracts and options thereon and exchange listed 
and OTC options on currencies.
 
  Forward currency contracts involve a privately negotiated 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. Currency swaps are agreements to 
exchange cash flows based on the notional difference between or among two or 
more currencies. See  "Swap  Agreements." 
 
  The use of currency transactions to protect the value of the Fund's assets 
against a decline in the value of a currency does not eliminate potential 
losses arising from fluctuations in the value of the Fund's underlying 
securities. Further, the Fund may enter into currency transactions only with 
counterparties that Wellington Management deems to be creditworthy.

  The Fund may also enter into options and futures contracts relative to 
foreign currency to hedge against fluctuations in foreign currency rates. See 
"Options and Futures Contracts" for a discussion of risk factors relating to 
foreign currency transactions including options and futures contracts related 
thereto.
 
OPTIONS AND FUTURES CONTRACTS

  In seeking to protect against the effect of changes in equity market 
values, currency exchange rates or interest rates that are adverse to the 
present or prospective position of the Fund, for cash flow management, and, 
to a lesser extent, to enhance returns, the Fund may employ certain hedging, 

                                      -8-

<PAGE>

income enhancement and risk management techniques, including the purchase and 
sale of options, futures and options on futures involving equity and debt 
securities and foreign currencies, aggregates of equity and debt securities, 
indices of prices of equity and debt securities and other financial indices. 
The Fund's ability to engage in these practices may be limited by tax 
considerations and certain other legal considerations.
 
  The Fund may write covered options and purchase put and call options on 
individual  securities as a partial hedge against an adverse movement in the 
security and in circumstances consistent with the objective and policies of 
the Fund. This strategy limits potential capital appreciation in the 
portfolio securities subject to the put or call option.
 
  The Fund may also write covered put and call options and purchase put and 
call options on foreign currencies to hedge against the risk of foreign 
exchange fluctuations on foreign securities the Fund holds in its portfolio 
or that it intends to purchase. For example, if the Fund enters into a 
contract to purchase securities denominated in foreign currency, it could 
effectively establish the maximum U.S. dollar cost of the securities by 
purchasing call options on that foreign currency. Similarly, if the Fund held 
securities denominated in a foreign currency and anticipated a decline in the 
value of that currency against the U.S. dollar, the Fund could hedge against 
such a decline by purchasing a put option on the foreign currency involved.
 
  In addition, the Fund may purchase put and call options and write covered 
put and call options on aggregates of equity and debt securities, and may 
enter into futures contracts and options thereon for the purchase or sale of 
aggregates of equity and debt securities, indices of equity and debt 
securities and other financial indices, all for the purpose of protecting 
against potential changes in the market value of portfolio securities or in 
interest rates. Aggregates are composites of equity or debt securities that 
are not tied to a commonly known index. An index is a measure of the value of 
a group of securities or other interests. An index assigns relative values to 
the securities included in that index, and the index fluctuates with changes 
in the market value of those securities.
 
  The Fund may write covered options only. "Covered" means that, so long as 
the Fund is obligated as the writer of a call option on particular securities 
or currency, it will own either the underlying securities or currency or an 
option to purchase the same underlying securities or currency having an 
expiration date not earlier than the expiration date of the covered option 
and an exercise price equal to or less than the exercise price of the covered 
option, or will establish or maintain with its custodian for the term of the 
option a segregated account consisting of cash, U.S. Government securities or 
other liquid, high grade debt obligations having a value equal to the 
fluctuating market value of the optioned securities or currencies. The Fund 
will cover any put option it writes on particular securities or currency by 
maintaining a segregated account with its custodian as described above.

  To hedge against fluctuations in currency exchange rates, the Fund may 
purchase or sell foreign currency futures contracts, and write put and call 
options and purchase put and call options on such futures contracts. For 
example, the Fund may use foreign currency futures contracts when

                                      -9-

<PAGE>

it anticipates a general weakening of the foreign currency exchange rate that 
could adversely affect the market values of the Fund's foreign securities 
holdings. In this case, the sale of futures contracts on the underlying 
currency may reduce the risk of a reduction in market value caused by foreign 
currency variations and, by so doing, provide an alternative to the 
liquidation of securities positions in the Fund and resulting transaction 
costs. When the Fund anticipates a significant foreign exchange rate increase 
while intending to invest in a non-U.S. security, the Fund may purchase a 
foreign currency futures contract to hedge against a rise in foreign exchange 
rates pending completion of the anticipated transaction. Such a purchase of a 
futures contract would serve as a temporary measure to protect the Fund 
against any rise in the foreign exchange rate that may add additional costs 
to acquiring the non-U.S. security position. The Fund similarly may use 
futures contracts on equity and debt securities to hedge against fluctuations 
in the value of securities it owns or expects to acquire.
 
  The Fund also may purchase call or put options on foreign currency futures 
contracts to obtain a fixed foreign exchange rate at limited risk. The Fund 
may purchase a call option on a foreign currency futures contract to hedge 
against a rise in the foreign exchange rate while intending to invest in a 
non-U.S. security of the same currency. The Fund may purchase put options on 
foreign currency futures contracts to hedge against a decline in the foreign 
exchange rate or the value of its non-U.S. securities. The Fund may write a 
call option on a foreign currency futures contract as a partial hedge against 
the effects of declining foreign exchange rates on the value of non-U.S. 
securities and in circumstances consistent with the Fund's investment 
objectives and policies.
 
  Options on indexes are settled in cash, not in delivery of securities. The 
exercising holder of an index option receives, instead of a security, cash 
equal to the difference between the closing price of the securities index and 
the exercise price of the option. When the Fund writes a covered option on an 
index, the Fund will be required to deposit and maintain with a custodian 
cash or high-grade, liquid short-term debt securities equal in value to the 
aggregate exercise price of a put or call option pursuant to the requirements 
and the rules of the applicable exchange. If, at the close of business on any 
day, the market value of the deposited securities falls below the contract 
price, the Fund will deposit with the custodian cash or high-grade, liquid 
short-term debt securities equal in value to the deficiency.

  To the extent that the Fund enters into futures contracts, options on 
futures contracts and options on foreign currencies that are traded on an 
exchange regulated by the Commodities Futures Trading Commission ("CFTC"), in 
each case that are not for "BONA FIDE hedging" purposes (as defined by 
regulations of the CFTC), the aggregate initial margin and premiums required 
to establish those positions may not exceed 5% of the liquidation value of 
the Fund's  portfolio, after taking into account the unrealized profits and 
unrealized losses on any such contracts the Fund has entered into. However, 
the "in-the-money" amount of such options may be excluded in computing the 5% 
limit. Adoption of this guideline will not limit the percentage of the Fund's 
assets at risk to 5%.
 
  Although the Fund may not employ all or any of the foregoing strategies, 
its use of options, futures and options thereon and forward currency 
contracts (as described under "Currency Transactions") would involve certain 
investment risks and transaction costs to which it might not

                                     -10-

<PAGE>

be subject were such strategies not employed. Such risks include: (1) 
dependence on the ability of Wellington Management to predict movements in 
the prices of individual securities, fluctuations in the general securities 
markets or market sections and movements in interest rates and currency 
markets; (2) imperfect correlation between movements in the price of the 
securities or currencies hedged or used for cover; (3) the fact that skills 
and techniques needed to trade options, futures contracts and options thereon 
or to use forward currency contracts are different from those needed to 
select the securities in which the Fund invests; (4) lack of assurance that a 
liquid secondary market will exist for any particular option, futures 
contract, option thereon or forward contract at any particular time, which 
may affect the Fund's ability to establish or close out a position; (5) 
possible impediments to effective portfolio management or the ability to meet 
current obligations caused by the segregation of a large percentage of the 
Fund's assets to cover its obligations; and (6) the possible need to defer 
closing out certain options, futures contracts, options thereon and forward 
contracts in order to continue to qualify for the beneficial tax treatment 
afforded "regulated investment companies" under the Code. In the event that 
the anticipated change in the price of the securities or currencies that are 
the subject of such a strategy does not occur, it may be that the Fund would 
have been in a better position had it not used such a strategy at all.

SWAP AGREEMENTS
 
  The Fund may enter into interest rate swaps, currency swaps, and other 
types of swap agreements such as caps, collars, and floors. In a typical 
interest rate swap, one party agrees to make regular payments equal to a 
floating interest rate multiplied by a "notional principal amount," in return 
for payments equal to a fixed rate multiplied by the same amount, for a 
specified period of time. If a swap agreement provides for payments in 
different currencies, the parties might agree to exchange the notional 
principal amount as well. Swaps may also depend on other prices or rates, 
such as the value of an index or mortgage prepayment rates.
 
  In a typical cap or floor agreement, one party agrees to make payments only 
under specified circumstances, usually in return for payment of a fee by the 
other party. For example, the buyer of an interest rate cap obtains the right 
to receive payments to the extent that a specified interest rate exceeds an 
agreed-upon level, while the seller of an interest rate floor is obligated to 
make payments to the extent that a specified interest rate falls below an 
agreed-upon level. An interest rate collar combines elements of buying a cap 
and selling a floor.
 
  Swap agreements will tend to shift the Fund's investment exposure from one 
type of investment to another. For example, if the Fund agreed to exchange 
floating rate payments for fixed rate payments, the swap agreement would tend 
to decrease the Fund's exposure to rising interest rates. Caps and floors 
have an effect similar to buying or writing options. Depending on how they 
are used, swap agreements may increase or decrease the overall volatility of 
the Fund's investments and its share price and yield.

  The Fund will usually enter into interest rate swaps on a net basis, i.e., 
where the two parties make net payments with the Fund receiving or paying, as 
the case may be, only the net amount of

                                     -11-

<PAGE>

the two payments. The net amount of the excess, if any, of the Fund's 
obligations over its entitlement with respect to each interest rate swap will 
be U.S. Government Securities or other liquid high grade debt obligations 
having an aggregate net asset value at least equal to the accrued excess will 
be maintained by the Fund's custodian in a segregated account. If the Fund 
enters into a swap on other than a net basis, the Fund will maintain in the 
segregated account the full amount of the Fund's obligations under each such 
swap. The Fund may enter into swaps, caps, collars and floors with member 
banks of the Federal Reserve System, members of the New York Stock Exchange 
or other entities determined by Wellington Management, pursuant to procedures 
adopted and reviewed on an ongoing basis by the Board of Directors, to be 
creditworthy. If a default occurs by the other party to such transaction, the 
Fund will have contractual remedies pursuant to the agreements related to the 
transaction but such remedies may be subject to bankruptcy and insolvency 
laws which could affect such Fund's rights as a creditor.

  The swap market has grown substantially in recent years with a large number 
of banks and financial services firms acting both as principals and as agents 
utilizing standardized swap documentation. As a result, the swap market has 
become relatively liquid. Caps, collars and floors are more recent 
innovations and they are less liquid than swaps. There can be no assurance, 
however, that the Fund will be able to enter into interest rate swaps or to 
purchase interest rate caps, collars or floors at prices or on terms 
Wellington Management, as appropriate, believes are advantageous to the Fund. 
In addition, although the terms of interest rate swaps, caps, collars and 
floors may provide for termination, there can be no assurance that the Fund 
will be able to terminate an interest rate swap or to sell or offset interest 
rate caps, collars or floors that it has purchased. Because interest rate 
swaps, caps, collars and floors are privately negotiated transactions rather 
than publicly traded they may be considered to be illiquid securities.

  The successful utilization of hedging and risk management transactions 
requires skills different from those needed in the selection of the Fund's 
portfolio securities and depends on Wellington Management's ability to 
predict correctly the direction and degree of movements in interest rates. 
Although the Fund believes that use of the hedging and risk management 
techniques described above will benefit the Fund, if Wellington Management's 
judgment about the direction or extent of the movement in interest rates is 
incorrect, the Fund's overall performance would be worse than if it had not 
entered into any such transactions. For example, if the Fund had purchased an 
interest rate swap or an interest rate floor to hedge against its expectation 
that interest rates would decline but instead interest rates rose, the Fund 
would lose part or all of the benefit of the increased payments it would 
receive as a result of the rising interest rates because it would have to pay 
amounts to its counterparties under the swap agreement or would have paid the 
purchase price of the interest rate floor. These activities are commonly used 
when managing derivative investments.

ILLIQUID SECURITIES

  The Fund is permitted to invest in illiquid securities. No illiquid 
securities will be acquired if upon the purchase more than 15% of the Fund's 
net assets would consist of such securities. "Illiquid Securities" are 
securities that may not be sold or disposed of in the ordinary course of

                                     -12-

<PAGE>


business within seven days at approximately the price used to determine the 
Fund's net asset value. The Fund may purchase certain restricted securities 
commonly known as Rule 144A securities that can be resold to institutions and 
which may be determined to be liquid pursuant to policies and guidelines of 
the Board of Directors. The Fund may not be able to sell illiquid securities 
when Wellington Management considers it desirable to do so or may have to 
sell such securities at a price that is lower than the price that could be 
obtained if the securities were more liquid. A sale of illiquid securities 
may require more time and may result in higher dealer discounts and other 
selling expenses than does the sale of securities that are not illiquid. 
Illiquid securities also may be more difficult to value due to the 
unavailability of reliable market quotations for such securities, and 
investment in illiquid securities may have an adverse impact on net asset 
value.

  Under current interpretations of the SEC Staff, the following types of 
securities in which the Fund may invest will be considered illiquid: (1) 
repurchase agreements maturing in more than seven days; (2) certain 
restricted securities (securities whose public resale is subject to legal or 
contractual restrictions); (3) options, with respect to specific securities, 
not traded on a national securities exchange that are not readily marketable; 
and (4) any other securities in which the Fund may invest that are not 
readily marketable.

WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES

  The Fund is permitted to purchase or sell securities on a when-issued or 
delayed-delivery basis. When-issued or delayed-delivery transactions arise 
when securities are purchased or sold with payment and delivery taking place 
in the future in order to secure what is considered to be an advantageous 
price and yield at the time of entering into the transaction. While the Fund 
generally purchases securities on a when-issued basis with the intention of 
acquiring the securities, the Fund may sell the securities before the 
settlement date if Wellington Management deems it advisable. At the time the 
Fund makes the commitment to purchase securities on a when-issued basis, the 
Fund will record the transaction and thereafter reflect the value, each day, 
of such security in determining the net asset value of the Fund. At the time 
of delivery of the securities, the value may be more or less than the 
purchase price. The Fund will maintain, in a segregated account, cash, U.S. 
Government securities or other liquid, high-grade debt obligations having a 
value equal to or greater than the Fund's purchase commitments; likewise the 
Fund will segregate securities sold on a delayed-delivery basis.
 
OTHER INVESTMENT COMPANIES
 
  The Fund is permitted to invest in other investment companies.  Securities 
in certain countries are currently accessible to the Fund only through such 
investments. The investment in other investment companies is limited in 
amount and will involve the indirect payment of a portion of the expenses, 
including advisory fees, of such other investment companies.  The Fund will 
not purchase a security of an investment company if, as a result, (1) more 
than 10% of the Fund's assets would be invested in securities of other 
investment companies, (2) such purchase would result in more than 3% of the 
total outstanding voting securities of any one such investment company being 


                                     -13-

<PAGE>


held by the Fund; or (3) more than 5% of the Fund's assets would be invested 
in any one such investment company. 

PORTFOLIO SECURITIES LENDING

  The Fund may lend its portfolio securities to broker/dealers and other 
institutions as a means of earning interest income. The borrower will be 
required to deposit as collateral, cash, cash equivalents, U.S. government 
securities or other high quality liquid debt securities that at all times 
will be at least equal to 100% of the market value of the loaned securities 
and such amount will be maintained in a segregated account of the Fund. While 
the securities are on loan the borrower will pay the Fund any income accruing 
thereon. 

  Delays or losses could result if a borrower of portfolio securities becomes 
bankrupt or defaults on its obligation to return the loaned securities. The 
Fund may lend securities only if: (1) the loan is fully secured by 
appropriate collateral at all times; and (2) the value of all loaned 
securities of the Fund is not more than 33-1/3% of the Fund's total assets 
taken at the time of the loan.

                                MANAGEMENT OF THE FUND

OTHER INFORMATION ABOUT THE FUND

  The Fund is a diversified series of the Hartford Series Fund, Inc., an 
open-end investment company which was organized as a Maryland corporation on 
January 15, 1998.  The authorized capital stock of the Fund consists of 3 
billion shares of common stock, par value $0.001 per share (Common Stock).  
The Directors have authorized the issuance of two classes of shares of the 
Fund designated in each instance as Class IA and Class IB shares.

  The shares of the Fund are entitled to vote separately to approve 
investment advisory agreements or changes in investment restrictions, but 
shareholders of all series of the Company vote together in the election and 
selection of Directors and accountants. Shares of the Fund vote together as a 
class on matters that affect the Fund in substantially the same manner.  As 
to matters affecting a single class, shares of such class will vote 
separately. Shares of the Fund do not have cumulative voting rights. The 
Company and the Fund do not intend to hold annual meetings of shareholders 
unless required to do so by the 1940 Act or the Maryland statutes under which 
the Company is organized. Although Directors are not elected annually by the 
shareholders, shareholders have under certain circumstances the right to 
remove one or more Directors. If required by applicable law, a meeting will 
be held to vote on the removal of a Director or Directors of the Company if 
requested in writing by the holders of not less than 25% of the Company's 
outstanding shares.  The Fund's shares are fully paid, and nonassessable and, 
when issued, have no preference, preemptive, conversion or similar rights and 
are freely transferable.  With respect to the Fund's shares issued as 
described above under "Purchase of Fund Shares," as well as Fund shares which 
are not otherwise attributable to variable annuity contract owners or 
variable life policy holders, The Hartford Life Insurance Companies shall be 
the shareholders of record. Each of The Hartford Life Insurance Companies 
will vote all Fund shares, pro rata, according to the written instructions of 
the contract owners of the variable annuity contracts and the policy holders 
of the variable life contracts issued by it using the Fund as investment 
vehicles. This position is consistent with the policy of the SEC Staff.

  The Company's Articles of Incorporation provide that the Directors, 
officers and employees of the Company may be indemnified by the Company to 
the fullest extent permitted by Maryland law and the federal securities laws. 
The Company's Bylaws provide that the Fund shall indemnify each of its 
Directors, officers and employees against liabilities and expenses reasonably 
incurred by them, in connection with, or resulting from, any claim, action, 
suit or proceeding, threatened against or otherwise involving such Director, 
officer or employee, directly or indirectly, by reason of being or having 
been a Director, officer or employee of the Company. Neither the Articles of 
Incorporation nor the Bylaws authorize the Company to indemnify any Director 
or officer against any liability to


                                     -19-

which he or she would otherwise be subject by reason of or for willful 
misfeasance, bad faith, gross negligence or reckless disregard of such 
person's duties.

                          INVESTMENT MANAGEMENT ARRANGEMENTS

  The Fund has entered into an investment advisory agreement with HL 
Investment Advisors, Inc. ("HL Advisors").  The investment advisory agreement 
provides that HL Advisors, subject to the supervision and approval of the 
Fund's Board of Directors, is responsible for the management of the Fund. HL 
Advisors is responsible for investment management supervision of the Fund.  
Hartford Life Insurance Company ("Hartford Life"), a corporate affiliate of 
HL Advisors, provides administrative services to the Fund including 
administrative personnel, services, equipment and facilities and office space 
for proper operation of the Fund. Although Hartford Life has agreed to 
arrange for the provision of additional services necessary for the proper 
operation of the Fund, the Fund pays for these services directly.  

  With respect to the Fund, HL Advisors has entered into a sub-advisory 
investment management agreement with Wellington Management Company 
("Wellington Management").  Under the sub-advisory agreement, Wellington 
Management, subject to the general supervision of the Board of Directors and 
HL Advisors, is responsible for (among other things) the day-to-day 
investment and reinvestment of the assets of the Fund and furnishing the Fund 
with advice and recommendations with respect to investments and the purchase 
and sale of appropriate securities for the Fund.

  As provided by the investment advisory agreement, the Fund pays HL Advisors 
an investment management fee, which is accrued daily and paid monthly, equal 
on an annual basis to a stated percentage of the Fund's average daily net 
asset value.  HL Advisors, not the Fund, pays the subadvisory fees of 
Wellington Management as set forth in the Prospectus.
 
  No person other than HL Advisors or Wellington Management and their 
directors and employees regularly furnishes advice to the Fund with respect 
to the desirability of the Fund investing in, purchasing or selling 
securities. Wellington Management may from time to time receive statistical 
or other information regarding general economic factors and trends, from The 
Hartford and its affiliates.

  Securities held by the Fund may also be held by other funds and other 
clients for which Wellington Management or its respective affiliates provide 
investment advice. Because of different investment objectives or other 
factors, a particular security may be bought by Wellington Management for one 
or more clients when one or more clients are selling the same security. If 
purchases or sales of securities arise for consideration at or about the same 
time for any fund or client accounts (including other funds) for which 
Wellington Management act as an investment adviser, (including the Fund 
described herein) transactions in such securities will be made, insofar as 
feasible, for the respective funds and other client accounts in a manner 
deemed equitable to all.


                                     -20-

<PAGE>


To the extent that transactions on behalf of more than one client of 
Wellington Management or its respective affiliates during the same period may 
increase the demand for securities being purchased or the supply of 
securities being sold, there may be an adverse effect on price.

  Pursuant to the investment advisory agreement, subadvisory investment 
agreements and investment services agreements neither HL Advisors nor 
Wellington Management is liable to the Fund or its shareholders for any error 
of judgment or mistake of law or for any loss suffered by the Fund in 
connection with the matters to which its agreements relate, except a loss 
resulting from willful misfeasance, bad faith or gross negligence on the part 
of Wellington Management in the performance of its duties or from its 
reckless disregard of the obligations and duties under the applicable 
agreement.

   
  HL Advisors, whose principal business address is at 200 Hopmeadow Street, 
Simsbury, Connecticut and whose mailing address is P.O. Box 2999, Hartford, 
Connecticut 06104, was organized in 1981. As of December 31, 1997, HL 
Advisors had over $24 billion in assets under management. HL Advisors is a 
majority owned indirect subsidiary of The Hartford.   

  Wellington Management, 75 State Street, Boston, MA 02109, is a professional 
investment counseling firm that provides services to investment companies, 
employee benefit plans, endowments, foundations and other institutions and 
individuals. Wellington Management and its predecessor organizations have 
provided investment advisory services since 1928. As of December 31, 1997, 
Wellington Management had investment management authority with respect to 
approximately $175 billion in assets. Wellington Management is a 
Massachusetts Limited Liability Partnership. The three managing partners of 
Wellington Management are Robert W. Doran, Duncan M. McFarland and John R.

  The investment management agreement and subadvisory investment agreement 
continue in effect for two years from initial approval and from year to year 
thereafter if approved annually by a vote of a majority of the Directors of 
the Fund including a majority of the Directors who are not parties to an 
agreement or interested persons of any party to the contract, cast in person 
at a meeting called for the purpose of voting on such approval, or by holders 
of a majority of the Fund's outstanding voting securities. The contract 
automatically terminates upon assignment as defined under the 1940 Act. The 
investment advisory agreement may be terminated without penalty on 60 days' 
notice at the option of either party to the respective contract or by vote of 
the holders of a majority of the outstanding voting securities of the Fund. 
The subadvisory investment agreements and investment services agreements may 
be terminated at any time without the payment of any penalty by the Board of 
Directors, by vote of a majority of the outstanding voting securities of the 
Fund or by HL Advisors, upon 60 days' notice to Wellington Management, and by 
Wellington Management upon 90 days' written notice to HL Advisors (with 
respect to the Fund only). The subadvisory investment agreement and 
investment services agreement terminate automatically upon the termination of 
the corresponding investment advisory agreement.

  HL Advisors may make payments from time to time from its own resources, 
which may include the management fees paid by the Fund to compensate broker 
dealers, depository institutions, or other persons for providing distribution 
assistance and administrative services and to otherwise promote the sale of 
shares of the Fund including paying for the preparation, printing and 
distribution of prospectuses and sales literature or other promotional 
activities.

                                    FUND EXPENSES

  The Fund assumes and pays the following costs and expenses: interest; 
taxes; brokerage charges (which may be to affiliated broker-dealers); costs 
of preparing, printing and filing any amendments or supplements to the 
registration forms of the Fund and its securities; all federal and state 
registration, qualification and filing costs and fees, (except the initial 
costs and fees, which will be borne by Hartford Life), issuance and 
redemption expenses, transfer agency and dividend and distribution disbursing 
agency costs and expenses; custodian fees and expenses; accounting, auditing 
and legal expenses; fidelity bond and other insurance premiums; fees and 
salaries of directors, officers and employees of the Fund other than those 
who are also officers of Hartford Life; industry membership dues; all annual 
and semiannual reports and prospectuses mailed to the Fund's shareholders as 
well as all quarterly, annual and any other periodic report required to be 
filed with the SEC or with any state; any notices required by a federal or 
state regulatory authority, and any proxy solicitation materials directed to 
the Fund's shareholders as well as all printing, mailing and tabulation costs 
incurred in connection therewith, and any expenses incurred in connection 
with the holding of meetings of the Fund's shareholders and other 
miscellaneous expenses related directly to the Fund's operations and 
interest. Pursuant to the Rule 12b-1 plan adopted for the Class IB shares, 
the Class IB shares may pay for certain distribution related expenses in 
connection with activities primarily intended to result in the sale of Class 
IB shares.

                              DISTRIBUTION ARRANGEMENTS

  The Fund's shares are sold on a continuous basis by Hartford Securities 
Distribution Company (the "Distributor") to separate accounts sponsored by 
The Hartford and its affiliates.

                         PORTFOLIO TRANSACTIONS AND BROKERAGE

  The Fund has no obligation to deal with any dealer or group of dealers in 
the execution of transactions in portfolio securities.  Subject to any policy 
established by HL Advisors and the Board of Directors, Wellington Management 
is primarily responsible for the investment decisions of the Fund and the 
placing of its portfolio transactions.  In placing orders, it is the policy 
of the Fund to obtain the most favorable net results, taking into account 
various factors, including price, dealer spread or commission, if any, size 
of the transaction and difficulty of execution.  While Wellington Management 
generally seeks reasonably competitive spreads or commissions.  Wellington 
Management may direct brokerage transactions to broker/dealers who also sell 
The Hartford's variable annuity and variable life insurance contracts and the 
sale of such contracts may be taken into account by Wellington Management 
when allocating brokerage transactions.

  Wellington Management will generally deal directly with the dealers who 
make a market in the securities involved (unless better prices and execution 
are available elsewhere) if the securities are traded primarily in the 
over-the-counter market.  Such dealers usually act as principals for their 
own account.  On occasion, securities may be purchased directly from the 
issuer. Bonds and money market securities are generally traded on a net basis 
and do not normally involve either brokerage commissions or transfer taxes. 

  While Wellington Management seek to obtain the most favorable net results 
in effecting transactions in the Fund's portfolio securities, dealers who 
provide supplemental investment research to Wellington Management may receive 
orders for transactions from Wellington Management.  Such supplemental 
research services ordinarily consist of assessments and analyses of the 
business or prospects of a company, industry, or economic sector.  If, in the 
judgment of Wellington Management, the Fund will be benefited by such 
supplemental research services, Wellington Management is authorized to pay 
spreads or commissions to brokers or dealers furnishing such services which 
are in excess of spreads or commissions which another broker or dealer may 
charge for the same transaction. Information so received will be in addition 
to and not in lieu of the services required to be performed by Wellington 
Management under the investment advisory agreement or the sub-investment 
advisory agreement.  The expenses of Wellington Management will not 
necessarily be reduced as a result of the receipt of such supplemental 
information.  Wellington Management may use such supplemental research in 
providing investment advice to portfolios other than those for which the 
transactions are made.  Similarly, the Fund may benefit from such research 
obtained by Wellington Management for portfolio transactions for other 
clients.

  Investment decisions for the Fund will be made independently from those of 
any other clients that may be (or in the future may be) managed by Wellington 
Management or its affiliates.  If, however, accounts managed by Wellington 
Management are simultaneously engaged in the purchase of the same security, 
then, pursuant to general authorization of the Fund's Board of Directors, 
available securities may be allocated to the Fund or other client account and 
may be averaged as to price in whatever manner Wellington Management deems to 
be fair.  Such allocation and pricing may affect the amount of brokerage 
commissions paid by the Fund.  In some cases, this system


                                     -23-

<PAGE>


might adversely affect the price paid by the Fund (for example, during 
periods of rapidly rising or falling interest rates) or limit the size of the 
position obtainable for the Fund (for example, in the case of a small issue).

                           DETERMINATION OF NET ASSET VALUE

  The net asset value of the shares of the Fund is determined by Hartford 
Life, in the manner described in the Fund's Prospectus.  The Fund will be 
closed for business and will not price its shares on the following business 
holidays: New Year's Day, Martin Luther King Day, Presidents' Day, Good 
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and 
Christmas Day. Securities held by the Fund will be valued as follows:  Debt 
securities (other than short-term obligations) are valued on the basis of 
valuations furnished by an unaffiliated pricing service which determines 
valuations for normal institutional size trading units of debt securities. 
The Fund's short-term investments with a maturity of 60 days or less when 
purchased are valued at amortized cost, which approximates market value.  
Short-term investments with a maturity of more than 60 days when purchased 
are valued based on market quotations until the remaining days to maturity 
become less than 61 days.  From such time until maturity, the investments are 
valued at amortized cost.

  Equity securities are valued at the last sales price reported on principal 
securities exchanges (domestic or foreign).  If no sale took place on such 
day and in the case of certain equity securities traded over-the-counter, 
then such securities are valued at the mean between the bid and asked prices. 
 Securities quoted in foreign currencies are translated into U.S. dollars at 
the exchange rate at the end of the reporting period.  Options are valued at 
the last sales price; if no sale took place on such day, then options are 
valued at the mean between the bid and asked prices.  Securities for which 
market quotations are not readily available and all other assets are valued 
in good faith at fair value by, or under guidelines established by, the 
Fund's Board of Directors.

                          PURCHASE AND REDEMPTION OF SHARES

  For information regarding the purchase of Fund shares, see "Purchase of 
Fund Shares" in the Fund's Prospectus.

  For a description of how a shareholder may have the Fund redeem his/her 
shares, or how he/she may sell shares, see "Sale and Redemption of Shares" in 
the Fund's Prospectus.  

SUSPENSION OF REDEMPTIONS

  The Fund may not suspend a shareholder's right of redemption, or postpone 
payment for a redemption for more than seven days, unless the New York Stock 
Exchange (NYSE) is closed for other than customary weekends or holidays, or 
trading on the NYSE is restricted, or for any period during which an 
emergency exists as a result of which (1) disposal by the Fund of securities 
owned by it is not reasonably practicable, or (2) it is not reasonably 
practicable for the Fund to fairly


                                     -24-

<PAGE>


determine the value of its assets, or for such other periods as the 
Securities and Exchange Commission may permit for the protection of investors.

                                INVESTMENT PERFORMANCE

  STANDARDIZED AVERAGE ANNUAL TOTAL RETURN QUOTATIONS.  Average annual total 
return quotations for the Fund are computed by finding the average annual 
compounded rates of return that would cause a hypothetical investment made on 
the first day of a designated period to equal the ending redeemable value of 
such hypothetical investment on the last day of the designated period in 
accordance with the following formula:

                                   P(1+T)n  =  ERV
Where:
P =  a hypothetical initial payment of    n  =    number of years
     $1,000, less the maximum sales
     load applicable to the Fund

T =  average annual total return          ERV  =   ending redeemable value of
                                                   the hypothetical $1,000 
                                                   initial payment made at the
                                                   beginning of the designated
                                                   period (or fractional 
                                                   portion thereof)

The computation above assumes that all dividends and distributions made by 
the Fund are reinvested at net asset value during the designated period.  The 
average annual total return quotation is determined to the nearest 1/100 of 
1%.

  One of the primary methods used to measure performance is "total return." 
"Total return" will normally represent the percentage change in value of a 
class of the Fund, or of a hypothetical investment in a class of the Fund, 
over any period up to the lifetime of the class.  Unless otherwise indicated, 
total return calculations will assume the deduction of the maximum sales 
charge and usually assume the reinvestment of all dividends and capital gains 
distributions and will be expressed as a percentage increase or decrease from 
an initial value, for the entire period or for one or more specified periods 
within the entire period.  Total return calculations that do not reflect the 
reduction of sales charges will be higher than those that do reflect such 
charges. 


                                     -25-

<PAGE>


  Total return percentages for periods longer than one year will usually be 
accompanied by total return percentages for each year within the period 
and/or by the average annual compounded total return for the period.  The 
income and capital components of a given return may be separated and 
portrayed in a variety of ways in order to illustrate their relative 
significance.  Performance may also be portrayed in terms of cash or 
investment values, without percentages. Past performance cannot guarantee any 
particular future result.  In determining the average annual total return 
(calculated as provided above), recurring fees, if any, that are charged to 
all shareholder accounts are taken into consideration.  For any account fees 
that vary with the size of the account, the account fee used for purposes of 
the above computation is assumed to be the fee that would be charged to the 
mean account size of the Fund.

  The Fund's average annual total return quotations and yield quotations as 
they may appear in the Prospectus, this SAI or in advertising are calculated 
by standard methods prescribed by the SEC.

  The Fund may also publish its distribution rate and/or its effective 
distribution rate.  The Fund's distribution rate is computed by dividing the 
most recent monthly distribution per share annualized, by the current net 
asset value per share.  The Fund's effective distribution rate is computed by 
dividing the distribution rate by the ratio used to annualize the most recent 
monthly distribution and reinvesting the resulting amount for a full year on 
the basis of such ratio.  The effective distribution rate will be higher than 
the distribution rate because of the compounding effect of the assumed 
reinvestment. The Fund's yield is calculated using a standardized formula, 
the income component of which is computed from the yields to maturity of all 
debt obligations held by the Fund based on prescribed methods (with all 
purchases and sales of securities during such period included in the income 
calculation on a settlement date basis), whereas the distribution rate is 
based on the Fund's last monthly distribution.  The Fund's monthly 
distribution tends to be relatively stable and may be more or less than the 
amount of net investment income and short- term capital gain actually earned 
by the Fund during the month (see "Dividends, Capital Gains and Taxes" in the 
Fund's Prospectus).

  Other data that may be advertised or published about the Fund include the 
average portfolio quality, the average portfolio maturity and the average 
portfolio duration.

  STANDARDIZED YIELD QUOTATIONS.  The yield of a class is computed by 
dividing the class's net investment income per share during a base period of 
30 days, or one month, by the maximum offering price per share of the class 
on the last day of such base period in accordance with the following formula:
                                     a-b       (6)
                               2[(--------- +1)      -1]
                                     cd
Where:
a =  net investment income earned       c  = the average daily number of shares
     during the period attributable          of the subject class outstanding
     to the subject class                    during the period that were
                                             entitled to receive dividends

     b =  net expenses accrued for      d =  the maximum offering price per 
          the period attributable            share of the subjectNet investment
          to the subject class               income will be determined in 
                                             accordance with rules established
                                             by the SEC. 


                                     -26-

<PAGE>


  NON-STANDARDIZED PERFORMANCE.  In addition, in order to more completely 
represent the Fund's performance or more accurately compare such performance 
to other measures of investment return, the Fund also may include in 
advertisements, sales literature and shareholder reports other total return 
performance data ("Non-Standardized Return").  Non-Standardized Return may be 
quoted for the same or different periods as those for which Standardized 
Return is quoted; it may consist of an aggregate or average annual percentage 
rate of return, actual year-by-year rates or any combination thereof. 
Non-Standardized Return may or may not take sales charges into account; 
performance data calculated without taking the effect of sales charges into 
account will be higher than data including the effect of such charges.  All 
non-standardized performance will be advertised only if the standard 
performance data for the same period, as well as for the required periods, is 
also presented.

  GENERAL INFORMATION.  From time to time, the Fund may advertise its 
performance compared to similar funds using certain unmanaged indices, 
reporting services and publications.  Descriptions of some of the indices 
which may be used are listed below.

  The Standard & Poor's 500 Composite Stock Price Index is a well diversified 
list of 500 companies representing the U.S. Stock Market.

  In addition, from time to time in reports and promotions: (1) the Fund's 
performance may be compared to other groups of mutual funds tracked by: (a): 
Lipper Analytical Services, a widely used independent research firm which 
ranks mutual funds by overall performance, investment objectives, and assets; 
(b) Morningstar, Inc., another widely used independent research firm which 
ranks mutual funds by overall performance, investment objectives, and assets; 
or (c) other financial or business publications, such as Business Week, Money 
Magazine, Forbes and Barron's which provide similar information; (2) the 
Consumer Price Index (measure for inflation) may be used to assess the real 
rate of return from an investment in the Fund; (3) other statistics such as 
GNP, and net import and export figures derived form governmental 
publications, e.g., The Survey of Current Business or other independent 
parties, e.g.,the Investment Company Institute, may be used to illustrate 
investment attributes to the Fund or the general economic, business, 
investment, or financial environment in which the Fund operates; (4) various 
financial, economic and market statistics developed by brokers, dealers and 
other persons may be used to illustrate aspects of the Fund's performance; 
(5) the effect of tax-deferred compounding on the Fund's investment returns, 
or on returns in general, may be illustrated by graphs, charts, etc. where 
such graphs or charts would compare, at various points in time, the return 
from an investment in the Fund (or returns in general) on a tax-deferred 
basis (assuming reinvestment of capital gains and dividends and assuming one 
or


                                     -27-

more tax rates) with the return on a taxable basis; and (6) the sectors or 
industries in which the Fund invests may be compared to relevant indices or 
surveys (e.g., S&P Industry Surveys) in order to evaluate the Fund's 
historical performance or current or potential value with respect to the 
particular industry or sector. 

  The Fund's investment performance may be advertised in various financial 
publications, newspapers, magazines including the following:

  From time to time the Fund may publish the sales of shares of one or more
of the Funds on a gross or net basis and for various periods of time, and
compare such sales with sales similarly reported by other investment companies.

  The manner in which total return and yield are calculated is described 
above. 

                                        TAXES

  The Fund is treated as a separate entity for accounting and tax purposes. 
The Fund has qualified and elected or intends to qualify and elect to be 
treated as a "regulated investment company" under Subchapter M of the 
Internal Revenue Code of 1986, as amended (the "Code"), and intends to 
continue to so qualify in the future.  As such and by complying with the 
applicable provisions of the Code regarding the sources of its income, the 
timing of its distributions, and the diversification of its assets, the Fund 
will not be subject to federal income tax on taxable income (including net 
short-term and long-term capital gains) which is distributed to shareholders 
at least annually in accordance with the timing requirements of the Code.

  The Fund will be subject to a 4% non-deductible federal excise tax on 
certain amounts not distributed (and not treated as having been distributed) 
on a timely basis in accordance with annual minimum distribution 
requirements.  The Fund intends under normal circumstances to avoid liability 
for such tax by satisfying such distribution requirements.

  If the Fund acquires stock in certain non-U.S. corporations that receive at 
least 75% of their annual gross income from passive sources (such as 
interest, dividends, rents, royalties or capital gain) or hold at least 50% 
of their assets in investments producing such passive income ("passive 
foreign investment companies"), the Fund could be subject to federal income 
tax and additional interest charges on "excess distributions" received from 
such companies or gain from the sale of stock in such companies, even if all 
income or gain actually received by the Fund is timely distributed to its 
shareholders.  The Fund would not be able to pass through to its shareholders 
any credit or deduction for such a tax.  Certain elections may, if available, 
ameliorate these adverse tax consequences, but any such election would 
require the Fund to recognize taxable income or gain without the concurrent 
receipt of cash.  Any Fund that is permitted to acquire stock in foreign


                                     -29-

<PAGE>


corporations may limit and/or manage its holdings in passive foreign 
investment companies to minimize its tax liability or maximize its return 
from these investments.

  Foreign exchange gains and losses realized by the Fund in connection with 
certain transactions involving foreign currency-denominated debt securities, 
certain foreign currency futures and options, foreign currency forward 
contracts, foreign currencies, or payables or receivables denominated in a 
foreign currency are subject to Section 988 of the Code, which generally 
causes such gains and losses to be treated as ordinary income and losses and 
may affect the amount, timing and character of distributions to shareholders. 
 Any such transactions that are not directly related to the Fund's investment 
in stock or securities, possibly including speculative currency positions or 
currency derivatives not used for hedging purposes, may increase the amount 
of gain it is deemed to recognize from the sale of certain investments held 
for less than three months, which gain is limited under the Code to less than 
30% of its annual gross income, and could under future Treasury regulations 
produce income not among the types of "qualifying income" from which the Fund 
must derive at least 90% of its annual gross income. 

  The Fund may be subject to withholding and other taxes imposed by foreign 
countries with respect to their investments in foreign securities.  Tax 
conventions between certain countries and the U.S. may reduce or eliminate 
such taxes.  The Fund anticipates that it generally will not qualify to pass 
such foreign taxes and any associated tax deductions or credits through to 
its shareholders, who therefore generally will not report such amounts on 
their own tax returns.

  For Federal income tax purposes, the Fund is permitted to carry forward a 
net capital loss in any year to offset its own capital gains, if any, during 
the eight years following the year of the loss.  To the extent subsequent 
capital gains are offset by such losses, they would not result in federal 
income tax liability to the Fund and would not be distributed as such to 
shareholders.

  The Fund that invests in certain PIKs, zero coupon securities or certain 
deferred interest securities (and, in general, any other securities with 
original issue discount or with market discount if the Fund elects to include 
market discount in income currently) must accrue income on such investments 
prior to the receipt of the corresponding cash payments.  However, the Fund 
must distribute, at least annually, all or substantially all of its net 
income, including such accrued income, to shareholders to qualify as a 
regulated investment company under the Code and avoid federal income and 
excise taxes. Therefore, the Fund may have to dispose of its portfolio 
securities under disadvantageous circumstances to generate cash, or may have 
to leverage itself by borrowing the cash, to satisfy distribution 
requirements.

  Investment in debt obligations that are at risk of or in default presents 
special tax issues for any Fund that may hold such obligations.  Tax rules 
are not entirely clear about issues such as when the Fund may cease to accrue 
interest, original issue discount, or market discount, when and to what 
extent deductions may be taken for bad debts or worthless securities, how 
payments received on obligations in default should be allocated between 
principal and income, and whether exchanges of debt obligations in a workout 
context are taxable.  These and other issues will be addressed by any

                                     -30-

<PAGE>


Fund that may hold such obligations in order to reduce the risk of 
distributing insufficient income to preserve its status as a regulated 
investment company and seek to avoid becoming subject to federal income or 
excise tax.

  Limitations imposed by the Code on regulated investment companies like the 
Fund may restrict the Fund's ability to enter into futures, options, and 
forward transactions.

  Certain options, futures and forward foreign currency transactions 
undertaken by the Fund may cause the Fund to recognize gains or losses from 
marking to market even though its positions have not been sold or terminated 
and affect the character as long-term or short-term (or, in the case of 
certain currency forwards, options and futures, as ordinary income or loss) 
and timing of some capital gains and losses realized by the Fund.  Also, 
certain of the Fund's losses on its transactions involving options, futures 
or forward contracts and/or offsetting portfolio positions may be deferred 
rather than being taken into account currently in calculating the Fund's 
taxable income. Certain of the applicable tax rules may be modified if the 
Fund is eligible and chooses to make one or more of certain tax elections 
that may be available. These transactions may therefore affect the amount, 
timing and character of the Fund's distributions to shareholders.  The Fund 
will take into account the special tax rules (including consideration of 
available elections) applicable to options, futures or forward contracts in 
order to minimize any potential adverse tax consequences.

  The federal income tax rules applicable to interest rate swaps, caps and 
floors are unclear in certain respects, and the Fund may be required to 
account for these transactions in a manner that, in certain circumstances, 
may limit the degree to which it may utilize these transactions.

  The foregoing discussion relates solely to U.S. Federal income tax law as 
applicable to U.S. persons (i.e., U.S. citizens or residents and U.S. 
domestic corporations, partnerships, trusts or estates) subject to tax under 
such law. The discussion does not address special tax rules applicable to 
certain classes of investors, such as tax-exempt entities, insurance 
companies, and financial institutions.  Dividends, capital gain 
distributions, and ownership of or gains realized on the redemption 
(including an exchange) of the shares of the Fund may also be subject to 
state and local taxes.  Shareholders should consult their own tax advisers as 
to the federal, state or local tax consequences of ownership of shares of, 
and receipt of distributions from, the Fund in its particular circumstances.

  STATE AND LOCAL.  The Fund may be subject to state or local taxes in 
jurisdictions in which the Fund may be deemed to be doing business.  In 
addition, in those states or localities which have income tax laws, the 
treatment of the Fund and its shareholders under such laws may differ from 
their treatment under federal income tax laws, and investment in the Fund may 
have different tax consequences for shareholders than would direct investment 
in the Fund's portfolio securities.  Shareholders should consult their own 
tax advisers concerning these matters.
