THE HARTFORD SMALL COMPANY FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Small Company Fund seeks growth of
capital by investing primarily in stocks selected on the basis of potential for
capital appreciation.
    
 
   
The fund normally invests at least 65% of its total assets in common stocks of
companies with market capitalizations within the range represented by the
Russell 2000 Index. As of December 31, 1998 this range was between approximately
$4 million and $3.4 billion and the average market capitalization was $560
million.
    
 
Through fundamental analysis Wellington Management identifies companies that it
believes have substantial potential for near-term capital appreciation.
Wellington Management selects securities of companies that, in its opinion:
    -  have potential for above-average earnings growth,
 
    -  are undervalued in relation to their investment potential,
 
    -  have positive business and/or fundamental financial characteristics that
       are overlooked or misunderstood by investors, or
 
    -  are relatively obscure and undiscovered by the overall investment
       community.
 
Fundamental analysis of a company involves the assessment of such factors as its
business environment, management, balance sheet, income statement, anticipated
earnings, revenues, dividends, and other related measures of value.
 
- --------------------------------------------------------------------------------
    
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements. Because the fund concentrates on small
companies, its performance may be more volatile than that of a fund that invests
primarily in larger companies.
    
   
Stocks of smaller companies may be more risky than stocks of larger companies.
Many of these companies are young and have limited operating or business
history. Because these businesses frequently rely on narrow product lines and
niche markets, they can suffer severely from isolated business setbacks.
    
    
The fund's management strategy will influence performance significantly. Small
company stocks as a group could fall out of favor with the market, causing the
fund to underperform funds that focus on other types of stocks. Similarly, if
the managers' stock selection strategy doesn't perform as expected, the fund
could underperform its peers or lose money.
     
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable distributions.
    
 
- --------------------------------------------------------------------------------
 
   
PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of a broad-based market index for comparison). The bar chart figures do not
include the effect of sales charges, while the average annual total return
figures do. If sales charges were reflected in the bar chart, returns would have
been lower. All figures assume that all dividends and distributions were
reinvested. Keep in mind that past performance does not indicate future results.

(1) Although the Rule 12b-1 fee for Class A shares is 0.35% of average net
    assets, the fund's distributor has voluntarily agreed to reduce the fee to
    0.30%. This waiver may be discontinued at any time.

(2) HIFSCO has voluntarily agreed to limit the total operating expenses of the
    Class A, Class B and Class C shares of the fund, exclusive of taxes,
    interest, brokerage commissions, certain distribution fees and extraordinary
    expenses as follows: 1.45% for Class A, 2.15% for Classes B and C. This
    policy may be discontinued at any time.

   
EXAMPLE.  This example is intended to help you compare the cost of investing in
the fund with the cost of investing in other mutual funds. The example assumes
that you invest $10,000 in the fund for the time periods indicated and then
redeem all of your shares at the end of those periods. The example also assumes
that your investment has a 5% return each year, that the fund's operating

THE HARTFORD CAPITAL APPRECIATION FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Capital Appreciation Fund seeks growth
of capital by investing primarily in stocks selected on the basis of potential
for capital appreciation.
    
    
The fund normally invests at least 65% of its total assets in common stocks of
small, medium and large companies.
    
    
Through fundamental analysis, Wellington Management identifies companies that it
believes have substantial near-term capital appreciation potential regardless of
company size or industry sector. This strategy is sometimes referred to as a
"stock picking" approach. Small and medium sized companies are selected
primarily on the basis of dynamic earnings growth potential. Larger companies
are selected primarily based on the expectation of a significant event that
Wellington Management believes will trigger an increase in the stock price.
     
In analyzing a prospective investment Wellington Management looks at a number of
factors, such as business environment, management, balance sheet, income
statement, anticipated earnings, revenues, dividends and other related measures
of value.
 
- --------------------------------------------------------------------------------
    
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements. Because the fund concentrates on small,
medium and large companies, its performance may be more volatile than that of a
fund that invests primarily in larger companies.
     
   
Stocks of small or mid-sized companies may be more risky than stocks of larger
companies. These companies may be young and have more limited operating or
business history. Because these businesses frequently rely on narrower product
lines and niche markets, they can suffer from isolated business setbacks.
    
    
The fund's management strategy will influence performance significantly. If the
managers' stock selection strategy doesn't perform as expected, the fund could
underperform its peers or lose money.
     
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable distributions.
    
 
- --------------------------------------------------------------------------------
 
   
PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of a broad-based market index for comparison). The bar chart figures do not
include the effect of sales charges, while the average annual total return
figures do. If sales charges were reflected in the bar chart, returns would have
been lower. All figures assume that all dividends and distributions were
reinvested. Keep in mind that past performance does not indicate future results.

THE HARTFORD MIDCAP FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford MidCap Fund seeks long-term growth of
capital by investing primarily in stocks selected on the basis of potential for
capital appreciation.
    
 
   
The fund normally invests at least 65% of its total assets in common stocks of
companies with market capitalizations within the range represented by the
Standard & Poor's MidCap 400 Index. As of December 31, 1998 this range was
between approximately $142 million and $11.6 billion and the average market
capitalization was $2.2 billion.
    
 
The fund uses a two-tiered investment strategy:
   
    -  Using what is sometimes referred to as a "top down" approach, Wellington
       Management analyzes the general economic and investment environment. This
       includes an evaluation of economic conditions, U.S. fiscal and monetary
       policy, and demographic trends. Through top down analysis, Wellington
       Management anticipates trends and changes in markets and the economy
       overall and identifies industries and sectors that are expected to
       outperform.
     
    -  Top down analysis is followed by what is sometimes referred to as a
       "bottom up" approach, which is the use of fundamental analysis to
       identify specific securities for purchase or sale. Fundamental analysis
       involves the assessment of a company through such factors as its business
       environment, management, balance sheet, income statement, anticipated
       earnings, revenues, and other related measures of value.
 
   
The fund favors high-quality growth companies. The key characteristics of
high-quality growth companies include a leadership position within an industry,
a strong balance sheet, a high return on equity, and a strong management team.
    
 
- --------------------------------------------------------------------------------
    
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements. Because the fund concentrates on
mid-sized companies, its performance may be more volatile than that of a fund
that invests primarily in larger companies.
     
   
Stocks of mid-sized companies may be more risky than stocks of larger companies.
These companies may be young and have more limited operating or business
history. Because these businesses frequently rely on narrower product lines and
niche markets, they can suffer from isolated business setbacks.
    
    
The fund's management strategy will influence performance significantly.
Mid-sized company stocks as a group could fall out of favor with the market,
causing the fund to underperform funds that focus on other types of stocks.
Similarly, if the managers' stock selection strategy doesn't perform as
expected, the fund could underperform its peers or lose money.
     
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable distributions.

PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart indicates the fund's total return for one calendar
year while the table shows the fund's performance over time (along with that of
a broad based market index for comparison). The bar chart figures do not include

If sales charges were reflected in the bar chart, returns would have been lower.

THE HARTFORD INTERNATIONAL OPPORTUNITIES FUND
- --------------------------------------------------------------------------------
    
INVESTMENT GOAL AND STYLE.  The Hartford International Opportunities Fund seeks
growth of capital by investing primarily in stocks issued by non-U.S. companies.
     
   
The fund normally invests at least 65% of its assets in stocks issued by
non-U.S. companies which trade in foreign markets generally considered to be
well established. Under normal market conditions the fund diversifies its
investments among at least three countries other than the United States. The
securities in which the fund invests are denominated in both U.S. dollars and
non-U.S. currencies and generally are traded in non-U.S. markets.
    
 
Wellington Management uses a three-pronged investment strategy:
 
    -  Wellington Management determines the relative attractiveness of the many
       countries in which the fund may invest based upon its analysis of the
       economic and political environment of each country.
 
    -  Wellington Management also evaluates industries on a global basis to
       determine which industries offer the most potential for capital
       appreciation given current and projected global and local economic and
       market conditions.
    
    -  Wellington Management conducts fundamental research on individual
       companies to identify securities for purchase or sale. Fundamental
       analysis of a company involves the assessment of such factors as its
       business environment, management, balance sheet, income statement,
       anticipated earnings, revenues, dividends, and other related measures of
       value.
     
   
In analyzing companies for investment, Wellington Management considers companies
for inclusion in the fund's portfolio that are typically larger, high-quality
companies that operate in established markets. Characteristics of high-quality
growth companies include a strong balance sheet, attractive industry trends,
strong competitive advantages and attractive relative value within the context
of a security's primary trading market.
    
 
- --------------------------------------------------------------------------------
    
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements.
     
   
Foreign investments may be more risky than domestic investments. Investments in
foreign securities may be affected by fluctuations in currency exchange rates,
incomplete or inaccurate financial information on companies, social upheavals
and political actions ranging from tax code changes to governmental collapse.
    
    
The fund's management strategy will influence performance significantly. If the
fund invests in countries or regions that experience economic downturns,
performance could suffer. Similarly, if certain investments or industries don't
perform as expected, or if the managers' stock selection strategy doesn't
perform as expected, the fund could underperform its peers or lose money.
     
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable distributions.

PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of a broad-based market index for comparison). The bar chart figures do not
include the effect of sales charges, while the average annual total return
figures do. If sales charges were reflected in the bar chart, returns would have
been lower. All figures assume that all dividends and distributions were
reinvested. Keep in mind that past performance does not indicate future results.

THE HARTFORD GLOBAL LEADERS FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Global Leaders Fund seeks growth of
capital by investing primarily in stocks issued by U.S. companies and non-U.S.
companies.
    
 
   
The fund invests primarily in a diversified portfolio of common stocks covering
a broad range of countries, industries and companies. Securities in which the
fund invests are denominated in both U.S. dollars and non-U.S. currencies and
may trade in both U.S. and non-U.S. markets.
    
 
   
Under normal market and economic conditions, the fund invests at least 65% of
its total assets in common stocks of high-quality growth companies worldwide.
These companies must, in the opinion of Wellington Management, be leaders in
their respective industries as indicated by an established market presence and
strong global, regional or country competitive positions. Under normal market
and economic conditions, the fund will diversify its investments in securities
of issuers among at least five countries, which may include the United States.
There are no limits on the amount of the fund's assets that may be invested in
each country.
    
 
The fund uses a two-tiered investment strategy:
 
   
    -  Using what is sometimes referred to as a "top down" approach, Wellington
       Management analyzes the global macro-economic and
       investment environments. This includes an evaluation of U.S. and non-U.S.
       economic and political conditions, fiscal and monetary policies,
       demographic trends and investor sentiment. Through top down analysis,
       Wellington Management anticipates trends and changes in the markets and
       economy to identify companies which offer the most potential for capital
       appreciation given current and projected global and local economic and
       market conditions.
    
 
    -  Top down analysis is followed by what is sometimes referred to as a
       "bottom up" approach, which is the use of fundamental analysis to
       identify specific securities for purchase or sale. Fundamental analysis
       involves the assessment of a company through such factors as its business
       environment, management, balance sheet, income statements, anticipated
       earnings, revenues and other related measures of value.
 
   
The fund emphasizes high-quality growth companies. The key characteristics of
high-quality growth companies include a strong balance sheet, a high return on
equity, a strong management team, and attractive relative value within the
context of the global marketplace or a security's primary trading market.
    
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements.
    
 
   
Foreign investments may be more risky than domestic investments. Investments in
foreign securities may be affected by fluctuations in currency exchange rates,
incomplete or inaccurate financial information on companies, social upheavals
and political actions ranging from tax code changes to governmental collapse.
    
 
   
The fund's management strategy will influence performance significantly. If the
fund invests in countries or regions that experience economic downturns,
performance could suffer. Similarly, if certain investments or industries don't
perform as expected, or if the managers' stock selection strategy doesn't
perform as expected, the fund could underperform its peers or lose money.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable distributions.

PAST PERFORMANCE.  Because the fund has been in operation for less than one year
no performance history has been provided.

THE HARTFORD STOCK FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Stock Fund seeks long-term growth of
capital, with income as a secondary consideration, by investing primarily in
stocks.
    
 
   
The fund normally invests at least 65% of the fund's total assets in the common
stocks of high-quality growth companies. Many of the companies in which the fund
invests have a history of paying dividends and are expected to continue paying
dividends in the future. The fund invests in a diversified portfolio of
primarily equity securities using a two-tiered investment strategy:
    
    
    -  Using what is sometimes referred to as a "top down" approach, Wellington
       Management analyzes the general economic and investment environment. This
       includes an evaluation of economic conditions, U.S. fiscal and monetary
       policy, demographic trends, and investor sentiment. Through top down
       analysis, Wellington Management anticipates trends and
       changes in markets in the economy overall and identifies industries and
       sectors that are expected to outperform.
    
    
    -  Top down analysis is followed by what is sometimes referred to as a
       "bottom up" approach, which is the use of fundamental analysis to
       identify specific securities for purchase or sale. Fundamental analysis
       of a company involves the assessment of such factors as its business
       environment, management, balance sheet, income statement, anticipated
       earnings, revenues, dividends, and other related measures of value.
     
   
The key characteristics of high-quality growth companies favored by the fund
include a leadership position within an industry, a strong balance sheet, a high
return on equity, sustainable or increasing dividends, a strong management team
and a globally competitive position.
    
 
- --------------------------------------------------------------------------------
    
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements.
    
    
The fund's management strategy will influence performance significantly.
Large-capitalization stocks as a group could fall out of favor with the market,
causing the fund to underperform funds that focus on small- or
medium-capitalization stocks. Similarly, if the managers' stock selection
strategy doesn't perform as expected, the fund could underperform its peers or
lose money.
     
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable distributions.
    
 
- --------------------------------------------------------------------------------
 
   
PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of a broad-based market index for comparison). The bar chart figures do not
include the effect of sales charges, while the average annual total return
figures do. If sales charges were reflected in the bar chart, returns would have
been lower. All figures assume that all dividends and distributions were
reinvested. Keep in mind that past performance does not indicate future results.

THE HARTFORD GROWTH AND INCOME FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Growth and Income Fund seeks growth of
capital and current income by investing primarily in stocks with earnings growth
potential and steady or rising dividends.
    
 
   
The fund invests primarily in a diversified portfolio of common stocks 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 of a company involves the
assessment of such factors as its business environment, management, balance
sheet, income statement, anticipated earnings, revenues, dividends and other
related measures of value.
    
 
   
Wellington Management then complements its fundamental research with an
internally-developed analytical approach. This analytical approach consists of
both valuation and timeliness measures. Valuation factors focus on future
dividend growth and cash flow to determine the relative attractiveness of
different stocks in different industries. Timeliness focuses on stocks with
favorable earnings and stock price momentum to assess the appropriate time for
purchase.
    
 
The fund's portfolio is broadly diversified by industry and company.
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements.
    
 
   
The fund's management strategy will influence performance significantly. If the
fund's stock selection strategy doesn't perform as expected, the fund could
underperform its peers or lose money.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable distributions.

THE HARTFORD DIVIDEND AND GROWTH FUND
    
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Dividend and Growth Fund seeks a high
level of current income consistent with growth of capital by investing primarily
in stocks.
    
    
The fund invests primarily in a diversified portfolio of common stocks that
typically have above average income yields and whose prospects for capital
appreciation are considered favorable by Wellington Management. Under normal
market and economic conditions at least 65% of the fund's total assets are
invested in dividend-paying equity securities. The fund tends to focus on
securities of larger, well-established companies.
    
    
Wellington Management uses fundamental analysis to evaluate a security for
purchase or sale by the fund. Fundamental analysis of a company involves the
assessment of such factors as its business environment, management, balance
sheet, income statement, anticipated earnings, revenues and dividends.
     
   
As a key component of its fundamental analysis, Wellington Management evaluates
a company's ability to sustain and potentially increase its dividend payments.
    
 
The fund's portfolio is broadly diversified by industry and company.
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements.
    

   
The fund's management strategy will influence performance significantly. If the
fund's stock selection strategy doesn't perform as expected, the fund could
underperform its peers or lose money.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable distributions.
    
 
- --------------------------------------------------------------------------------
 
   
PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of a broad-based market index for comparison). The bar chart figures do not
include the effect of sales charges, while the average annual total return
figures do. If sales charges were reflected in the bar chart, returns would have

THE HARTFORD ADVISERS FUND
    
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Advisers Fund seeks maximum long-term
total return by investing in stocks, bonds and other debt securities and money
market instruments.
    
 
   
The fund favors stocks issued by high-quality growth companies. The key
characteristics of high-quality growth companies include a leadership position
within an industry, a strong balance sheet, a high return on equity, sustainable
or increasing dividends, a strong management team and a globally competitive
position.
    
 
   
The debt securities in which the fund primarily invests include securities
issued or guaranteed by the U.S. Government and its agencies or
instrumentalities and securities rated investment grade (rated at least BBB by
Standard & Poor's Corporation or Baa by Moody's Investors Service, Inc., or if
unrated, securities deemed by Wellington Management to be of comparable quality.
The fund is not restricted to any specific maturity term.
    
    
Asset allocation decisions are based on Wellington Management's judgment of the
projected investment environment for financial assets, relative fundamental
values, the attractiveness of each asset category, and expected future returns
of each asset category. Wellington Management does not attempt to engage in
short-term market timing among asset categories. As a result, shifts in asset
allocation are expected to be gradual and continuous and the fund will normally
have some portion of its assets invested in each asset category. There is no
limit on the amount of fund assets that may be allocated to each asset category
and the allocation is in Wellington Management's discretion.
     
- --------------------------------------------------------------------------------
    
MAIN RISKS.  This fund has stock market risk, interest rate risk, manager
allocation risk, credit risk and prepayment risk. You could lose money as a
result of your investment.
    
    
Stock market risk means the stocks held by the fund may decline in value due to
the activities and financial prospects of individual companies or to general
market and economic conditions.
    
   
Interest rate risk refers to the possibility that your investment may go down in
value when interest rates rise.
    
    
Manager allocation risk refers to the possibility that the portfolio managers
could incorrectly allocate assets so that the fund underperforms its peers.
    
    
Credit risk refers to the possibility that the issuing company may not be able
to pay interest and principal when due.
     
   
Prepayment risk refers to the possibility that any mortgage securities held by
the fund may be adversely affected by changes in prepayment rates on the
underlying mortgages. If prepayments increase as a result of lower interest
rates the fund may have to invest a portion of its assets at lower rates.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable distributions.
    
 
- --------------------------------------------------------------------------------
 
   
PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of broad-based market indices for comparison). The bar chart figures do not
include the effect of sales charges, while the average annual total return
figures do. If sales charges were reflected in the bar chart, returns would have
been lower. All figures assume that all dividends and distributions were
reinvested. Keep in mind that past performance does not indicate future results.

THE HARTFORD HIGH YIELD FUND
    
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford High Yield Fund seeks high current
income by investing in non-investment grade debt securities. Growth of capital
is a secondary objective.
    
 
   
The fund normally invests at least 65%, and may invest up to 100%, of its
portfolio in non-investment grade debt securities (securities rated "Ba" or
lower by Moody's Investors Service, Inc. ("Moody's") or "BB" or lower by
Standard and Poor's Corporation ("S&P"), or securities which, if unrated, are
determined by HIMCO to be of comparable quality). Below investment grade
securities are commonly referred to as "high yield-high risk securities" or
"junk bonds". The fund will invest no more than 10% of total assets in
securities rated below B3 by Moody's or B- by S&P, or if unrated, determined to
be of comparable quality by HIMCO. The fund may invest in bonds of any maturity
although the fund tends to have an average maturity within the intermediate-term
range.
    
 
   
The fund may invest up to 15% of its total assets in preferred stocks,
convertible securities, and securities carrying warrants to purchase equity
securities. The fund will not invest in common stocks directly, but may retain,
for reasonable periods of time, common stocks acquired upon conversion of debt
securities or upon exercise of warrants acquired with debt securities. The fund
may invest up to 30% of its total assets in securities of non-U.S. issuers.
    
 
   
To achieve its goal of high current income, the fund uses what is sometimes
referred to as a top-down analysis to determine which industries may benefit
from current and future changes in the economy. The fund then selects individual
securities within selected industries that appear from a yield perspective to be
attractive. The fund assesses such factors as the company's business
environment, balance sheet, income statement, anticipated earnings and
management team.
    
 
   
The fund seeks its secondary goal of capital growth, when consistent with its
primary objective of high current income, by investing in securities that the
portfolio manager expects to appreciate in value as a result of declines in
long-term interest rates or favorable developments affecting the business or
prospects of the issuer which may improve the issuer's financial condition and
credit rating.
    
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  The major factors affecting this fund's performance are interest
rates and credit risk. When interest rates rise, bond prices fall; generally the
longer a bond's maturity, the more sensitive it is to this risk.
    
 
   
Credit risk depends largely on the perceived financial health of bond issuers.
In general, lower-rated bonds have higher credit risks. Junk bond prices can
fall on bad news about the economy, an industry or a company. Share price, yield
and total return may fluctuate more than with less aggressive bond funds.
    
 
   
The fund could lose money if any bonds it owns are downgraded in credit rating
or go into default. If certain industries or investments don't perform as the
fund expects, it could underperform its peers or lose money.
    
 
   
Junk bonds and foreign securities may make the fund more sensitive to market or
economic shifts in the U.S. and abroad.
    
 
   
In a down market some of the fund's investments could become harder to value.
    
 
   
Any U.S. government guarantees on portfolio securities do not apply to the
market value or current yield of the portfolio's securities or to the value of
the fund's shares.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable distributions.

PAST PERFORMANCE.  Because the fund has been in operation for less than one year
no performance history is provided.

THE HARTFORD BOND INCOME STRATEGY FUND
- --------------------------------------------------------------------------------
    
INVESTMENT GOAL AND STYLE.  The Hartford Bond Income Strategy Fund seeks a high
level of current income, consistent with a competitive total return, as compared
to bond funds with similar investment objectives and policies, by investing
primarily in debt securities. Debt securities include (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); (3) asset-backed and mortgage-related securities; and (4)
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.
     
   
The fund normally invests at least 70% of its portfolio in investment grade debt
securities. The fund may invest up to 30% of its total assets in securities
rated in the highest category of below investment grade bonds ("Ba1", "Ba2" or
"Ba3" by Moody's Investors Service, Inc. or "BB+", "BB" or "BB-" by Standard and
Poor's Corporation), or securities which, if unrated, are determined by HIMCO to
be of comparable quality. Securities rated below investment grade are commonly
referred to as "junk bonds".
    
 
   
The fund invests at least 65% of its total assets in debt securities with a
maturity of at least one year. Although the fund does not have a maximum
maturity term restriction, the fund tends to have an average maturity within the
intermediate-term range. The fund may invest up to 15% of its total assets in
preferred stocks, convertible securities, and securities accompanied by warrants
to purchase equity securities. The fund will not invest in common stocks
directly, but may retain, for reasonable periods of time, common stocks acquired
upon conversion of debt securities or upon exercise of warrants acquired with
debt securities. The fund may invest up to 30% of its total assets in debt
securities of non-U.S. companies.
    
    
The fund uses what is sometimes referred to as a top-down analysis to determine
which industries may benefit from current and future changes in the economy. The
fund then selects individual securities that appear comparatively undervalued
within selected industries. The portfolio manager assesses such factors as a
company's business environment, balance sheet, income statement, anticipated
earnings and management team.
     
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  The major factors affecting this fund's performance are interest
rates and credit risk. When interest rates rise, bond prices fall; generally the
longer the fund's maturity, the more sensitive it is to this risk.
    
    
The fund could lose money if any bonds it owns are downgraded in credit rating
or go into default. In general, lower-rated bonds have higher credit risks. If
certain sectors or investments don't perform as the fund expects, it could
underperform its peers or lose money.
    
    
Junk bonds and foreign securities may make the fund more sensitive to market or
economic shifts in the U.S. and abroad.
    
    
In a down market some of the fund's investments could become harder to value.
     
   
Any U.S. government guarantees on portfolio securities do not apply to the
market value or current yield of the portfolio's securities or to the value of
the fund's shares.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable distributions.

PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of a broad-based market index for comparison). The bar chart figures do not
include the effect of sales charges, while the average annual total return
figures do. If sales charges were reflected in the bar chart, returns would have
been lower. All figures assume that all dividends and distributions were
reinvested. Keep in mind that past performance does not indicate future results.

THE HARTFORD MONEY MARKET FUND
- --------------------------------------------------------------------------------
 
INVESTMENT GOAL AND STYLE.  The Hartford Money Market Fund seeks maximum current
income consistent with liquidity and preservation of capital. The fund seeks to
maintain a stable share price of $1.00.
 
   
The fund focuses on specific short-term money market instruments such as debt
securities issued by corporations and financial institutions which are rated in
the first two investment tiers by at least one nationally recognized statistical
rating organization, or if unrated, determined to be of comparable quality by
HIMCO. 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.
    
    
The fund purchases securities which it believes offer attractive returns
relative to the risks undertaken. In addition, the portfolio manager adjusts the
average maturity of the portfolio in anticipation of interest rate changes.
     
- --------------------------------------------------------------------------------
    
MAIN RISKS.  An investment in the fund is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency. Although
the fund seeks to preserve the value of your investment at $1.00 per share,
there is a risk that the fund's share price could fall below $1.00, which would
reduce the value of your account.
     
- --------------------------------------------------------------------------------
 
   
PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of a broad-based market index for comparison). The bar chart year-by-year
figures do not include the effect of sales charges as no front-end sales charge
is applicable to the Class A shares of this fund. All figures assume that all
dividends and distributions were reinvested. Keep in mind that past performance
does not indicate future results.

(1) Although the Rule 12b-1 fee for Class A shares is 0.35% of average net
    assets, the fund's distributor has voluntarily agreed to reduce the fee to
    0.30%. This waiver may be discontinued at any time.

(2) HIFSCO has voluntarily agreed to limit the total operating expenses of the
    Class A, Class B and Class C shares of the fund, exclusive of taxes,
    interest, brokerage commissions, certain distribution fees and extraordinary
    expenses as follows: 1.00% for Class A, 1.70% for Classes B and C. This
    policy may be discontinued at any time.
 
   
EXAMPLE.  This example is intended to help you compare the cost of investing in
the fund with the cost of investing in other mutual funds. The example assumes
that you invest $10,000 in the fund for the time periods indicated and then
redeem all of your shares at the end of those periods. The example also assumes
that your investment has a 5% return each year, that the fund's operating
expenses remain the same and that you reinvest all dividends and distributions.
Although your actual costs may be higher or lower, based on these assumptions
your costs would be:

PRIOR PERFORMANCE OF SIMILAR FUNDS
- --------------------------------------------------------------------------------
 
   
Because the mutual funds that are the subject of this prospectus (the "Retail
Funds") began operations in July, 1996, or later, they have limited operating
and performance histories. However, the Capital Appreciation Fund, International
Opportunities Fund, Stock Fund, Dividend and Growth Fund and Advisers Fund are
modeled after existing funds (the "HLS Funds") that are managed by the same
portfolio managers at HIMCO or Wellington Management and have investment
objectives, policies and strategies substantially similar to those of the
corresponding funds. Depending on the fund involved, similarity of investment
characteristics may involve factors such as industry diversification, country
diversification, portfolio beta, portfolio quality, average maturity of
fixed-income assets, equity/non-equity mixes, and individual holdings. The HLS
Funds are used as investment vehicles for the assets of variable annuity and
variable life insurance contracts issued by The Hartford affiliates.
    
 
   
Below you will find information about the performance of the HLS Funds. Because
the expenses of the HLS Funds are generally lower than the Retail Funds the
performance of the HLS Funds would have been lower had the Retail Funds expenses
been applied.
    
 
The table below sets forth each fund, its corresponding HLS Fund, and their
respective inception date and asset sizes as of December 31, 1998. Any fund's
future performance may be greater or less than the performance of the
corresponding HLS Fund due to, among other things, differences in expenses,
asset sizes and cash flows between a fund and the corresponding HLS Fund.

The following table shows the average annualized total returns for the HLS Funds
for the one, three, five and ten year (or life of the HLS Fund, if shorter)
periods ended December 31, 1998. These figures are based on the actual gross
investment performance of the HLS Funds. From the gross investment performance
figures, the maximum Total Fund Operating Expenses for each Retail Fund are
deducted to arrive at the net return. Please remember that past performance is
not indicative of future returns.

ADDITIONAL INVESTMENT MATTERS
- --------------------------------------------------------------------------------
 
 USE OF OPTIONS AND FUTURES
 
Each fund (other than the Money Market fund) may purchase and sell options and
enter into futures contracts, in each case with respect to stocks, bonds, groups
of securities (such as financial indices) or foreign currencies. These
techniques permit a fund to gain exposure to a particular security or group of
securities, and thereby earn returns similar to those which would be earned by
direct investments in those securities. These techniques are also used to manage
risk by hedging a fund's portfolio investments. Use of these techniques may
result in losses to a fund or increase volatility.
 
 USE OF MONEY MARKET INVESTMENTS
 FOR TEMPORARY DEFENSIVE PURPOSES
 
From time to time each fund (other than the Money Market fund) may invest some
or all of its assets in high quality money market securities for temporary
defensive purposes in response to adverse market, economic or political
conditions. To the extent a fund is in a defensive position, the fund may lose
the benefit of upswings and may not achieve its investment objective.
 
 ABOUT EACH FUND'S INVESTMENT GOAL
 
Each fund's investment goal may be changed without approval of the shareholders
of the fund. A fund may not be able to achieve its goal.

 TAX CONSEQUENCES OF PORTFOLIO
 TRADING PRACTICES
 
   
At times each fund may engage in short-term trading, which could produce higher
brokerage expenses for a fund and higher taxable distributions to the fund's
shareholders. The funds are not managed to achieve a particular tax result for
shareholders. Shareholders should consult their own tax adviser for individual
tax advice.
    
 
 YEAR 2000
 
   
The services provided to the funds by HIFSCO, 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. HIFSCO, 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. In addition, to the extent that a
company in a fund's portfolio suffers from a Year 2000 problem, a fund's
performance could be adversely affected.

ABOUT YOUR ACCOUNT
- --------------------------------------------------------------------------------
 
 CHOOSING A SHARE CLASS
 
Each share class has its own cost structure, allowing you to choose the one that
best meets your needs. Your financial representative can help you decide.
 
 CLASS A
 
- - Front-end sales charges, as described at right.
 
- - Distribution and service (12b-1) fees of 0.35% (currently 0.30% due to waiver
  by the distributor).
 
 CLASS B
 
- - No front-end sales charge; all your money goes to work for you right away.
 
- - Distribution and service (12b-1) fees of 1.00%.
 
- - A deferred sales charge, as described on the following page.
 
- - Automatic conversion to Class A shares after eight years, thus reducing future
  annual expenses.
 
 CLASS C
 
- - 1% front-end sales charge.
 
- - Distribution and service (12b-1) fees of 1.00%
 
- - A 1.00% contingent deferred sales charge on shares sold within one year of
  purchase.
 
- - No automatic conversion to Class A shares, so annual expenses continue at the
  Class C level throughout the life of your investment.
 
For actual past expenses of each share class, see the fund-by-fund information
earlier in this prospectus.
 
   
Each class has adopted Rule 12b-1 plans which allow the class to pay
distribution fees for the sale and distribution of its shares. Because these
fees are paid out of a fund's assets on an ongoing basis, over time these fees
will increase the cost of your investment and may cost you more than paying
other types of sales charges.
    

 
 HOW SALES CHARGES ARE CALCULATED
 
   
CLASS A sales charges for the Small Company Fund, Capital Appreciation Fund,
MidCap Fund, International Opportunities Fund, Global Leaders Fund, Stock Fund,
Growth and Income Fund, Dividend and Growth Fund and Advisers Fund are listed
below. The term offering price includes the front end sales load.

(1) Investments of $1 million or more in Class A shares may be made with no
    front-end sales charge. However, there is a contingent deferred sales charge
    (CDSC) of 1% on any shares sold within 18 months of purchase. For purposes
    of this CDSC, all purchases made during a calendar month are counted as
    having been made on the first day of that month. The CDSC is based on the
    lesser of the original purchase cost or the current market value of the
    shares being sold, and is not charged on shares you acquired by reinvesting
    your dividends. To keep your CDSC as low as possible, each time you place a
    request to sell shares we will first sell any shares in your account that
    are not subject to a CDSC.
    
 
CLASS B shares are offered at their net asset value per share, without any
initial sales charge. However, you may be charged a contingent deferred sales
charge (CDSC) on shares you sell within a certain time after you bought them, as
described in the tables below. There is no CDSC on shares acquired through
reinvestment of dividends. The CDSC is based on the original purchase cost or
the current market value of

the shares being sold, whichever is less. The CDSCs are as follows:

Because in most cases it is more advantageous for an investor to purchase Class
A shares for amounts in excess of $500,000, orders for amounts of $500,000 or
greater will be considered purchases of Class A shares.
 
CLASS C sales charges for all funds are as follows:

Because in most cases it is more advantageous for an investor to purchase Class
A shares for amounts in excess of $1,000,000, orders for amounts of $1,000,000
or greater will be considered purchases of Class A shares.
 
For purposes of Class B and Class C CDSCs, all purchases made during a calendar
month are counted as having been made on the first day of that month. CDSC
calculations are based on the number of shares involved, not on the value of
your account. To keep your CDSC as low as possible, each time you place a
request to sell shares we will first sell any shares in your account that carry
no CDSC. If there are not enough of these to meet your request, we will sell
those shares that have the lowest CDSC.
 
 SALES CHARGE REDUCTIONS AND WAIVERS
 
REDUCING YOUR CLASS A SALES CHARGES  There are several ways you can combine
multiple purchases of Class A shares of the funds to take advantage of the
breakpoints in the sales charge schedule. The first three ways can be combined
in any manner:
 
- - ACCUMULATION PRIVILEGE -- lets you add the value of any shares of the funds
  you or members of your family already own to the amount of your next Class A
  investment for purposes of calculating the sales charge. In addition, if you
  are a natural person who owns a Hartford Director (or version thereof)
  variable annuity or single premium variable life contract, the current account
  value of your contract or policy will be included. You must notify your broker
  that you are eligible for this privilege each time you make a purchase.
 
- - LETTER OF INTENTION -- lets you purchase Class A shares of a fund over a
  13-month period and receive the same sales charge as if all shares had been
  purchased at once.
 
- - COMBINATION PRIVILEGE -- lets you combine Class A shares of multiple funds for
  purposes of calculating the sales charge.
 
CDSC WAIVERS  As long as the transfer agent is notified at the time you sell,
the CDSC for each share class will generally be waived in the following cases:
 
- - to make payments through certain systematic withdrawal plans,
 
- - to make certain distributions from a retirement plan,
 
- - because of shareholder death or disability,
 
- - because of the death or disability of the grantor of a living trust.
 
In addition, the CDSC is waived for redemptions made under reorganization,
liquidation, merger or acquisition transactions involving other investment
companies.
 
REINSTATEMENT PRIVILEGE  If you sell shares of a fund, you may reinvest some or
all of the proceeds in the same share class of any fund within 180 days without
a sales charge, as long as the transfer agent is notified before you invest. If
you paid a CDSC when you sold your shares, you will be credited with the amount
of the CDSC. All accounts involved must have the same registration.
 
WAIVERS FOR CERTAIN INVESTORS  Class A shares may be offered without front-end
sales charges or CDSCs to various individuals and institutions, including:
 
- - selling brokers and their employees and sales representatives,
 
- - financial representatives utilizing fund shares in fee-based investment
  products under signed agreement with the funds,
 
- - present or former officers, directors and employees (and their families) of
  the funds, The Hartford, Wellington Management, the transfer agent, and their
  affiliates,
 
- - participants in certain retirement plans with at least 100 eligible employees
  or if the total amount invested is $500,000 or more (18-month CDSC applies),
 
- - individuals purchasing shares with the proceeds from shares redeemed within
  the last 60 days on which an initial or contingent deferred sales charge was
  paid,
 
- - one or more members of a group (including spouses and dependent children) of
  at least 100 persons engaged, or previously engaged in a common business,
  profession, civic or charitable endeavor or other activity.

TRANSACTION POLICIES
- --------------------------------------------------------------------------------
 
 VALUATION OF SHARES
    
The net asset value per share (NAV) for each fund and class is determined each
business day at the close of regular trading on the New York Stock Exchange
("NYSE") (typically 4 P.M. Eastern Time). Except for the Money Market Fund, the
funds use market prices in valuing portfolio securities, but may use fair-value
estimates, as determined in good faith by the Board of Directors, if reliable
market prices are unavailable. The Money Market Fund's assets are valued at
amortized cost.
    
    
Trading on many foreign securities markets is completed at various times before
or after the close of the NYSE or on days the NYSE is not open for business.
Consequently, the calculation of a fund's NAV may take place at a time that is
different than when prices are determined for certain foreign securities. As a
result, events affecting the values of foreign portfolio securities that occur
after the close of the NYSE will not be reflected in a fund's calculation of
NAV.
    
 BUY AND SELL PRICES
 
When you buy shares, you pay the NAV plus any applicable sales charges, as
described earlier. When you sell shares, you receive the NAV minus any
applicable deferred sales charges.

 EXECUTION OF REQUESTS
 
Each fund is open on those days when the New York Stock Exchange is open,
typically Monday through Friday. Buy and sell requests are executed at the next
NAV to be calculated after your request is received by the transfer agent or
authorized broker-dealers and third-party administrators.
 
At times of peak activity, it may be difficult to place requests by phone.
During these times, consider sending your request in writing.
 
In unusual circumstances, any fund may temporarily suspend the processing of
sell requests, or may postpone payment of proceeds for up to three business days
or longer, as allowed by federal securities laws.

 TELEPHONE TRANSACTIONS
 
For your protection, telephone requests may be recorded in order to verify their
accuracy. Also for your protection, telephone transactions are not permitted on
accounts whose names or addresses have changed within the past 30 days. Proceeds
from telephone transactions can only be mailed to the address of record.

 EXCHANGES
 
You may exchange shares of one fund for shares of the same class of any other,
generally without paying any
additional sales charges (except when exchanging from Class A shares of the
Money Market Fund). The registration for both accounts involved must be
identical. Class B shares will continue to age from the original date of
purchase.
 
   
Each fund reserves the right to refuse or delay exchanges by any person or group
if, in HIMCO's or Wellington Management's judgment, a fund would be unable to
invest the money effectively in accordance with its investment objective and
policies, or would otherwise potentially be adversely affected. Your exchanges
may be restricted or refused if a fund receives or anticipates simultaneous
orders affecting significant portions of the fund's assets. In particular, a
pattern of exchanges that coincides with a "market timing" strategy may be
disruptive to the fund. Although a fund will attempt to give you prior notice
whenever it is reasonably able to do so, it may impose these restrictions at any
time. Each fund reserves the right to terminate or modify the exchange privilege
in the future.
    
 
 CERTIFICATED SHARES
 
Shares are electronically recorded and therefore share certificates are not
issued.
 
 SMALL ACCOUNTS
 (NON-RETIREMENT ONLY)
 
If you draw down a non-retirement account so that its total value is less than
$1,000, you may be asked to purchase more shares within 30 days. If you do not
take action, your fund may close out your account and mail you the proceeds. You
will not be charged a CDSC if your account is closed for this reason, and your
account will not be closed if its drop in value is due to fund performance or
the effects of sales charges.
 
 SALES IN ADVANCE OF
 PURCHASE PAYMENTS
 
When you place a request to sell shares for which the purchase money has not yet
been collected, the request will be executed in a timely fashion, but the fund
will not release the proceeds to you until your purchase payment clears. This
may take up to 15 business days after the purchase.
 
 SPECIAL REDEMPTIONS
 
   
Although it would not normally do so, each fund has the right to pay the
redemption price of shares of the fund in whole or in part in portfolio
securities as prescribed by the Directors. When the shareholder sells portfolio
securities received in this fashion, he would incur a brokerage charge. Any such
securities would be

valued for the purposes of making such payment at the same value as used in
determining net asset value. The funds have elected to be governed by Rule 18f-1
under the 1940 Act, pursuant to which each fund is obligated to redeem shares
solely in cash up to the lesser of $250,000 or 1% of the net asset value of the
applicable fund during any 90 day period for any one account.
    
 
 PAYMENT REQUIREMENTS
 
   
All of your purchases must be made in U.S. dollars and checks must be drawn on
U.S. banks and made payable to The Hartford Mutual Funds, Inc., or in the case
of a retirement account, to the custodian or trustee. You may not purchase
shares with a third party check.
    
 
 DIVIDENDS AND ACCOUNT POLICIES
 
ACCOUNT STATEMENTS  In general, you will receive account statements as follows:
 
- - after every transaction (except a dividend reinvestment) that affects your
  account balances
 
- - after any changes of name or address of the registered owner(s)
 
- - in all other circumstances, every quarter
 
DIVIDENDS  Each fund intends to distribute substantially all of its net income
and capital gains to shareholders at least once a year. Normally, dividends from
net investment income of the Small Company Fund, Capital Appreciation Fund,
MidCap Fund, International Opportunities Fund, Global Leaders Fund and Stock
Fund will be declared and paid annually; dividends from the net investment
income of the Growth and Income Fund, Dividend and Growth Fund and Advisers Fund
will be declared and paid quarterly; dividends from the net investment income of
the Bond Income Strategy Fund and High Yield Fund will be declared and paid
monthly and dividends from net investment income of the Money Market Fund will
be declared daily and paid monthly. Dividends from the Money Market Fund are not
paid on shares until the day following the date on which the shares are issued.
Unless shareholders specify otherwise, all dividends and distributions will be
automatically reinvested in additional full or fractional shares of each fund.
 
   
TAXABILITY OF DIVIDENDS  Dividends you receive from a fund, whether reinvested
or taken as cash, are generally considered taxable. Dividends from a fund's
long-term capital gains are taxable as capital gains; dividends from short-term
capital gains and income are generally taxable as ordinary income. Some
dividends paid in January may be taxable as if they had been paid the previous
December. Tax rates may vary depending on how long a fund investment is held.
See your application for distribution options.
    
 
The Form 1099 that is mailed to you every January details your dividends and
their federal tax category, although you should verify your tax liability with
your tax professional.
 
TAXABILITY OF TRANSACTIONS  Any time you sell or exchange shares, it is
considered a taxable event for you. Depending on the purchase price and the sale
price of the shares you sell or exchange, you may have a gain or a loss on the
transaction. You are responsible for any tax liabilities generated by your
transactions.
 
 ADDITIONAL INVESTOR SERVICES
 
ELECTRONIC TRANSFERS THROUGH AUTOMATED CLEARING HOUSE (ACH) NETWORK allow you to
initiate a purchase or redemption for as little as $100 or as much as $50,000
between your bank account and fund account using the ACH network. Sales charges
and initial purchase minimums apply.
 
AUTOMATIC INVESTMENT PLAN (AIP)  AIP lets you set up regular investments from
your paycheck or bank account to The Hartford Mutual Fund(s) of your choice. You
determine the frequency and amount of your investments, and you can terminate
your program at any time. To establish:
 
- - Complete the appropriate parts of your account application.
 
- - If you are using AIP to open an account, make out a check ($25 minimum) for
  your first investment amount payable to "The Hartford Mutual Funds, Inc."
  Deliver your check and application to your financial representative or the
  transfer agent.
 
SYSTEMATIC WITHDRAWAL PLAN  This plan may be used for routine bill payments or
periodic withdrawals from your account. To establish:
 
- - Make sure you have at least $5,000 worth of shares in your account and that
  the amount per transaction is $50 or more per fund.
 
- - Make sure you are not planning to invest more money in this account (buying
  shares during a period when you are also selling shares of the same fund is
  not advantageous to you, because of sales charges).
 
- - SPECIFY THE PAYEE(S).  The payee may be yourself or any other party, and there
  is no limit to the number of payees you may have, as long as they are all on
  the same payment schedule.
 
- - Determine the schedule: monthly, quarterly, semi-annually, annually or in
  certain selected months.
 
- - FILL OUT THE RELEVANT PART OF THE ACCOUNT APPLICATION. To add a systematic
  withdrawal plan to an existing account, contact your financial representative
  or the transfer agent.

DOLLAR COST AVERAGING PROGRAMS (DCA) let you set up monthly or quarterly
exchanges from one fund to the same class of shares of another fund. To
establish:
 
- - Fill out the relevant part of the account application.

THE HARTFORD SMALL COMPANY FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Small Company Fund seeks growth of
capital by investing primarily in stocks selected on the basis of potential for
capital appreciation.
    
 
   
The fund normally invests at least 65% of its total assets in common stocks of
companies with market capitalizations within the range represented by the
Russell 2000 Index. As of December 31, 1998 this range was between approximately
$4 million and $3.4 billion, and the average market capitalization was $560
million.
    
 
Through fundamental analysis Wellington Management identifies companies that it
believes have substantial potential for near-term capital appreciation.
Wellington Management selects securities of companies that, in its opinion:
    - have potential for above-average earnings growth,
 
    - are undervalued in relation to their investment potential,
 
    - have positive business and/or fundamental financial characteristics that
      are overlooked or misunderstood by investors, or
 
    - are relatively obscure and undiscovered by the overall investment
      community.
 
Fundamental analysis of a company involves the assessment of such factors as its
business environment, management, balance sheet, income statement, anticipated
earnings, revenues, dividends, and other related measures of value.
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements. Because the fund concentrates on small
companies, its performance may be more volatile than that of a fund that invests
primarily in larger companies.
    
   
Stocks of smaller companies may be more risky than stocks of larger companies.
Many of these companies are young and have limited operating or business
history. Because these businesses frequently rely on narrow product lines and
niche markets, they can suffer severely from isolated business setbacks.
    
 
   
The fund's management strategy will influence performance significantly. Small
company stocks as a group could fall out of favor with the market, causing the
fund to underperform funds that focus on other types of stocks. Similarly, if
the managers' stock selection strategy doesn't perform as expected, the fund
could underperform its peers or lose money.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable dividends.

PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of a broad-based market index for comparison). The bar chart year-by-year
figures and average annual figures do not include the effect of sales charges as
no sales charge is applicable to the Class Y shares. All figures assume that all
dividends and distributions were reinvested. Keep in mind that past performance
does not indicate future results.

THE HARTFORD CAPITAL APPRECIATION FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Capital Appreciation Fund seeks growth
of capital by investing primarily in stocks selected on the basis of potential
for capital appreciation.
    
 
   
The fund normally invests at least 65% of its total assets in common stocks of
small, medium and large companies.
    
 
   
Through fundamental analysis, Wellington Management identifies companies that it
believes have substantial near-term capital appreciation potential regardless of
company size or industry sector. This strategy is sometimes referred to as a
"stock picking" approach. Small and medium sized companies are selected
primarily on the basis of dynamic earnings growth potential. Larger companies
are selected primarily based on the expectation of a significant event that
Wellington Management believes will trigger an increase in the stock price.
    
 
In analyzing a prospective investment Wellington Management looks at a number of
factors, such as business environment, management, balance sheet, income
statement, anticipated earnings, revenues, dividends and other related measures
of value.
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements. Because the fund concentrates on small,
medium and large companies, its performance may be more volatile than that of a
fund that invests primarily in larger companies.
    
 
   
Stocks of small or mid-sized companies may be more risky than stocks of larger
companies. These companies may be young and have more limited operating or
business history. Because these businesses frequently rely on narrower product
lines and niche markets, they can suffer from isolated business setbacks.
    
 
   
The fund's management strategy will influence performance significantly. If the
managers' stock selection strategy doesn't perform as expected, the fund could
underperform its peers or lose money.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable dividends.

PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of a broad-based market index for comparison). The bar chart year-by-year
figures and average annual figures do not include the effect of sales charges as
no sales charge is applicable to the Class Y shares. All figures assume that all
dividends and distributions were reinvested. Keep in mind that past performance
does not indicate future results.

THE HARTFORD MIDCAP FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford MidCap Fund seeks long-term growth of
capital by investing primarily in stocks selected on the basis of potential for
capital appreciation.
    
 
   
The fund normally invests at least 65% of its total assets in common stocks of
companies with market capitalizations within the range represented by the
Standard & Poor's MidCap 400 Index. As of December 31, 1998 this range was
between approximately $142 million and $11.6 billion and the average market
capitalization was $2.2 billion.
    
 
The fund uses a two-tiered investment strategy:
 
   
    -  Using what is sometimes referred to as a "top down" approach, Wellington
       Management analyzes the general economic and investment environment. This
       includes an evaluation of economic conditions, U.S. fiscal and monetary
       policy, and demographic trends. Through top down analysis, Wellington
       Management anticipates trends and changes in markets and the economy
       overall and identifies industries and sectors that are expected to
       outperform.
    
 
    -  Top down analysis is followed by what is sometimes referred to as a
       "bottom up" approach, which is the use of fundamental analysis to
       identify specific securities for purchase or sale. Fundamental analysis
       involves the assessment of a company through such factors as its business
       environment, management, balance sheet, income statement, anticipated
       earnings, revenues, and other related measures of value.
 
The fund favors high-quality growth companies. The key characteristics of
high-quality growth companies include a leadership position within an industry,
a strong balance sheet, a high return on equity, and a strong management team.
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements. Because the fund concentrates on
mid-sized companies, its performance may be more volatile than that of a fund
that invests primarily in larger companies.
    
 
   
Stocks of mid-sized companies may be more risky than stocks of larger companies.
These companies may be young and have more limited operating or business
history. Because these businesses frequently rely on narrower product lines and
niche markets, they can suffer from isolated business setbacks.
    
 
   
The fund's management strategy will influence performance significantly.
Mid-sized company stocks as a group could fall out of favor with the market,
causing the fund to underperform funds that focus on other types of stocks.
Similarly, if the managers' stock selection strategy doesn't perform as
expected, the fund could underperform its peers or lose money.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable dividends.

in the fund. The bar chart indicates the fund's total return for one calendar
year while the table shows the fund's performance over time (along with that of
a broad based market index for comparison). The bar chart figures and average

THE HARTFORD INTERNATIONAL OPPORTUNITIES FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford International Opportunities Fund seeks
growth of capital by investing primarily in stocks issued by non-U.S. companies.
    
 
   
The fund normally invests at least 65% of its assets in stocks issued by
non-U.S. companies which trade in foreign markets generally considered to be
well established. Under normal market conditions the fund diversifies its
investments among at least three countries other than the United States. The
securities in which the fund invests are denominated in both U.S. dollars and
non-U.S. currencies and generally are traded in
    
non-U.S. markets.
 
Wellington Management uses a three-pronged investment strategy:
 
    - Wellington Management determines the relative attractiveness of the many
      countries in which the fund may invest based upon its analysis of the
      economic and political environment of each country.
 
    - Wellington Management also evaluates
      industries on a global basis to determine which
      industries offer the most potential for capital appreciation given current
      and projected
      global and local economic and market
      conditions.
 
    - Wellington Management conducts fundamental research on individual
      companies to identify securities for purchase or sale. Fundamental
      analysis of a company involves the assessment of such factors as its
      business environment, management, balance sheet, income statement,
      anticipated earnings, revenues, dividends, and other related measures of
      value.
 
   
In analyzing companies for investment, Wellington Management considers companies
for inclusion in the fund's portfolio that are typically larger, high quality
companies that operate in established markets. Characteristics of high quality
growth companies include a strong balance sheet, attractive industry trends,
strong competitive advantages and attractive relative value within the context
of a security's primary trading market.
    
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements.
    
 
   
Foreign investments may be more risky than domestic investments. Investments in
foreign securities may be affected by fluctuations in currency exchange rates,
incomplete or inaccurate financial information on companies, social upheavals
and political actions ranging from tax code changes to governmental collapse.
    
 
   
The fund's management strategy will influence performance significantly. If the
fund invests in countries or regions that experience economic downturns,
performance could suffer. Similarly, if certain investments or industries don't
perform as expected, or if the managers' stock selection strategy doesn't
perform as expected, the fund could underperform its peers or lose money.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable dividends.

PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of a broad-based market index for comparison). The bar chart year-by-year
figures and average annual figures do not include the effect of sales charges as
no sales charge is applicable to the Class Y shares. All figures assume that all
dividends and distributions were reinvested. Keep in mind that past performance
does not indicate future results.

THE HARTFORD GLOBAL LEADERS FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Global Leaders Fund seeks growth of
capital by investing primarily in stocks issued by U.S. companies and non-U.S.
companies.
    
 
   
The fund invests primarily in a diversified portfolio of common stocks covering
a broad range of countries, industries and companies. Securities in which the
fund invests are denominated in both U.S. dollars and non-U.S. currencies and
may trade in both U.S. and non-U.S. markets.
    
 
   
Under normal market and economic conditions, the fund invests at least 65% of
its total assets in common stocks of high-quality growth companies worldwide.
These companies must, in the opinion of Wellington Management, be leaders in
their respective industries as indicated by an established market presence and
strong global, regional or country competitive positions. Under normal market
and economic conditions, the fund will diversify its investments in securities
of issuers among at least five countries, which may include the United States.
There are no limits on the amount of the fund's assets that may be invested in
each country.
    
 
The fund uses a two-tiered investment strategy:
 
   
    -  Using what is sometimes referred to as a "top down" approach, Wellington
       Management analyzes the global macro-economic and
       investment environments. This includes an evaluation of U.S. and non-U.S.
       economic and political conditions, fiscal and monetary policies,
       demographic trends and investor sentiment. Through top down analysis,
       Wellington Management anticipates trends and changes in the markets and
       economy to identify companies which offer the most potential for capital
       appreciation given current and projected global and local economic and
       market conditions.
    
 
    -  Top down analysis is followed by what is sometimes referred to as a
       "bottom up" approach, which is the use of fundamental analysis to
       identify specific securities for purchase or sale. Fundamental analysis
       involves the assessment of a company through such factors as its business
       environment, management, balance sheet, income statements, anticipated
       earnings, revenues and other related measures of value.
 
   
The fund emphasizes high-quality growth companies. The key characteristics of
high-quality growth companies include a strong balance sheet, a high return on
equity, a strong management team, and attractive relative value within the
context of the global marketplace or a security's primary trading market.
    
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements.
    
 
   
Foreign investments may be more risky than domestic investments. Investments in
foreign securities may be affected by fluctuations in currency exchange rates,
incomplete or inaccurate financial information on companies, social upheavals
and political actions ranging from tax code changes to governmental collapse.
    
 
   
The fund's management strategy will influence performance significantly. If the
fund invests in countries or regions that experience economic downturns,
performance could suffer. Similarly, if certain investments or industries don't
perform as expected, or if the managers' stock selection strategy doesn't
perform as expected, the fund could underperform its peers or lose money.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable dividends.

PAST PERFORMANCE.  Because the fund has been in operation for less than one year
no performance history has been provided.

THE HARTFORD STOCK FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Stock Fund seeks long-term growth of
capital, with income as a secondary consideration, by investing primarily in
stocks.
    
 
   
The fund normally invests at least 65% of the fund's total assets in the common
stocks of high-quality growth companies. Many of the companies in which the fund
invests have a history of paying dividends and are expected to continue paying
dividends in the future. The fund invests in a diversified portfolio of
primarily equity securities using a two-tiered investment strategy:
    
 
   
    -  Using what is sometimes referred to as a "top down" approach, Wellington
       Management analyzes the general economic and investment environment. This
       includes an evaluation of economic conditions, U.S. fiscal and monetary
       policy, demographic trends, and investor sentiment. Through top down
       analysis, Wellington Management anticipates trends and changes in markets
       in the economy overall and identifies industries and sectors that are
       expected to outperform.
    
 
   
    -  Top down analysis is followed by what is sometimes referred to as a
       "bottom up" approach, which is the use of fundamental analysis to
       identify specific securities for purchase or sale. Fundamental analysis
       of a company involves the assessment of such factors as its business
       environment, management, balance sheet, income statement, anticipated
       earnings, revenues, dividends, and other related measures of value.
    
 
   
The key characteristics of high-quality growth companies favored by the fund
include a leadership position within an industry, a strong balance sheet, a high
return on equity, sustainable or increasing dividends, a strong management team
and a globally competitive position.
    
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements.
    
 
   
The fund's management strategy will influence performance significantly.
Large-capitalization stocks as a group could fall out of favor with the market,
causing the fund to underperform funds that focus on small- or
medium-capitalization stocks. Similarly, if the managers' stock selection
strategy doesn't perform as expected, the fund could underperform its peers or
lose money.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable dividends.
    
 
- --------------------------------------------------------------------------------
 
   
PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of a broad-based market index for comparison). The bar chart year-by-year
figures and average annual figures do not include the effect of sales charges as
no sales charge is applicable to the Class Y shares. All figures assume that all
dividends and distributions were reinvested. Keep in mind that past performance
does not indicate future results.

THE HARTFORD GROWTH AND INCOME FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL.  The Hartford Growth and Income Fund seeks growth of capital
and current income by investing primarily in stocks with earnings growth
potential and steady or rising dividends.
    
 
   
The fund invests primarily in a diversified portfolio of common stocks 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 of a company involves the
assessment of such factors as its business environment, management, balance
sheet, income statement, anticipated earnings, revenues, dividends and other
related measures of value.
    
 
   
Wellington Management then complements its fundamental research with an
internally-developed analytical approach. This analytical approach consists of
both valuation and timeliness measures. Valuation factors focus on future
dividend growth and cash flow to determine the relative attractiveness of
different stocks in different industries. Timeliness focuses on stocks with
favorable earnings and stock price momentum to assess the appropriate time for
purchase.
    
 
   
The fund's portfolio is broadly diversified by industry and company.
    
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements.

underperform its peers or lose money.

EXAMPLE.  This example is intended to help you compare the
cost of investing in the fund with the cost of investing
in other mutual funds. The example assumes that you invest
$10,000 in the fund for the time periods indicated and
then redeem all of your shares at the end of those
periods. The example also assumes that your investment has
a 5% return each year, that the fund's operating expenses
remain the same and that you reinvest all dividends and
distributions. Because no sales charges apply to the Class
Y shares you would have the same expenses whether or not
you redeemed your shares. Although your actual costs may
be higher or lower, based on these assumptions your costs
would be:

THE HARTFORD DIVIDEND AND GROWTH FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Dividend and Growth Fund seeks a high
level of current income consistent with growth of capital by investing primarily
in stocks.
    
 
   
The fund invests primarily in a diversified portfolio of common stocks that
typically have above average income yields and whose prospects for capital
appreciation are considered favorable by Wellington Management. Under normal
market and economic conditions at least 65% of the fund's total assets are
invested in dividend-paying equity securities. The fund tends to focus on
securities of larger, well-established companies.
    
 
   
Wellington Management uses fundamental analysis to evaluate a security for
purchase or sale by the fund. Fundamental analysis of a company involves the
assessment of such factors as its business environment, management, balance
sheet, income statement, anticipated earnings, revenues and dividends.
    
 
As a key component of its fundamental analysis, Wellington Management evaluates
a company's ability to sustain and potentially increase its dividend payments.
 
The fund's portfolio is broadly diversified by industry and company.
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  As with most stock funds, the value of your investment may go down
in response to stock market movements.
The fund's management strategy will influence performance significantly. If the
fund's stock selection strategy doesn't perform as expected, the fund could
underperform its peers or lose money.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable dividends.
    
 
- --------------------------------------------------------------------------------
 
   
PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of a broad-based market index for comparison). The bar chart year-by-year
figures and average annual figures do not include the effect of sales charges as
no sales charge is applicable to the Class Y shares. All figures assume that all
dividends and distributions were reinvested. Keep in mind that past performance
does not indicate future results.

THE HARTFORD ADVISERS FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Advisers Fund seeks maximum long-term
total return by investing in stocks, bonds and other debt securities and money
market instruments.
    
 
   
The fund favors stocks issued by high-quality growth companies. The key
characteristics of high-quality growth companies include a leadership position
within an industry, a strong balance sheet, a high return on equity, sustainable
or increasing dividends, a strong management team and a globally competitive
position.
    
 
   
The debt securities in which the fund primarily invests include securities
issued or guaranteed by the U.S. Government and its agencies or
instrumentalities and securities rated investment grade (rated at least BBB by
Standard & Poor's Corporation or Baa by Moody's Investors Service, Inc., or if
unrated, securities deemed by Wellington Management to be of comparable quality.
The fund is not restricted to any specific maturity term.
    
 
   
Asset allocation decisions are based on Wellington Management's judgment of the
projected investment environment for financial assets, relative fundamental
values, the attractiveness of each asset category, and expected future returns
of each asset category. Wellington Management does not attempt to engage in
short-term market timing among asset categories. As a result, shifts in asset
allocation are expected to be gradual and continuous and the fund will normally
have some portion of its assets invested in each asset category. There is no
limit on the amount of fund assets that may be allocated to each asset category
and the allocation is in Wellington Management's discretion.
    
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  This fund has stock market risk, interest rate risk, manager
allocation risk, credit risk and prepayment risk. You could lose money as a
result of your investment.
    
 
   
Stock market risk means the stocks held by the fund may decline in value due to
the activities and financial prospects of individual companies or to general
market and economic conditions.
Interest rate risk refers to the possibility that your investment may go down in
value when interest rates rise.
    
 
   
Manager allocation risk refers to the possibility that the portfolio managers
could incorrectly allocate assets so that the fund underperforms its peers.
    
 
   
Credit risk refers to the possibility that the issuing company may not be able
to pay interest and principal when due.
    
 
   
Prepayment risk refers to the possibility that any mortgage securities held by
the fund may be adversely affected by changes in prepayment rates on the
underlying mortgages. If prepayments increase as a result of lower interest
rates the fund may have to invest a portion of its assets at lower rates.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable dividends.

EXAMPLE.  This example is intended to help you compare the
cost of investing in the fund with the cost of investing
in other mutual funds. The example assumes that you invest

then redeem all of your shares at the end of those
periods. The example also assumes that your investment has
a 5% return each year, that the fund's operating expenses

Y shares you would have the same expenses whether or not
you redeemed your shares. Although your actual costs may

THE HARTFORD HIGH YIELD FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford High Yield Fund seeks high current
income by investing in non-investment grade debt securities. Growth of capital
is a secondary objective.
    
 
   
The fund normally invests at least 65%, and may invest up to 100%, of its
portfolio in non-investment grade debt securities (securities rated "Ba" or
lower by Moody's Investors Service, Inc. ("Moody's") or "BB" or lower by
Standard and Poor's Corporation ("S&P"), or securities which, if unrated, are
determined by HIMCO to be of comparable quality). Below investment grade
securities are commonly referred to as "high yield-high risk securities" or
"junk bonds". The fund will invest no more than 10% of total assets in
securities rated below B3 by Moody's or B- by S&P, or if unrated, determined to
be of comparable quality by HIMCO. The fund may invest in bonds of any maturity
although the fund tends to have an average maturity within the intermediate-term
range.
    
 
   
The fund may invest up to 15% of its total assets in preferred stocks,
convertible securities, and securities carrying warrants to purchase equity
securities. The fund will not invest in common stocks directly, but may retain,
for reasonable periods of time, common stocks acquired upon conversion of debt
securities or upon exercise of warrants acquired with debt securities. The fund
may invest up to 30% of its total assets in securities of non-U.S. issuers.
    
 
   
To achieve its goal of high current income, the fund uses what is sometimes
referred to as a top-down analysis to determine which industries may benefit
from current and future changes in the economy. The fund then selects individual
securities within selected industries that appear from a yield perspective to be
attractive. The fund assesses such factors as the company's business
environment, balance sheet, income statement, anticipated earnings and
management team.
    
 
   
The fund seeks its secondary goal of capital growth, when consistent with its
primary objective of high current income, by investing in securities that the
portfolio manager expects to appreciate in value as a result of declines in
long-term interest rates or favorable developments affecting the business or
prospects of the issuer which may improve the issuer's financial condition and
credit rating.
    
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  The major factors affecting this fund's performance are interest
rates and credit risk. When interest rates rise, bond prices fall; generally the
longer a bond's maturity, the more sensitive it is to this risk.
    
 
   
Credit risk depends largely on the perceived financial health of bond issuers.
In general, lower-rated bonds have higher credit risks. Junk bond prices can
fall on bad news about the economy, an industry or a company. Share price, yield
and total return may fluctuate more than with less aggressive bond funds.
    
 
   
The fund could lose money if any bonds it owns are downgraded in credit rating
or go into default. If certain industries or investments don't perform as the
fund expects, it could underperform its peers or lose money.
    
 
   
Junk bonds and foreign securities may make the fund more sensitive to market or
economic shifts in the U.S. and abroad.
    
 
   
In a down market some of the fund's investments could become harder to value.
    
 
   
Any U.S. government guarantees on portfolio securities do not apply to the
market value or current yield of the portfolio's securities or to the value of
the fund's shares.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable dividends.
    
 
- --------------------------------------------------------------------------------
 
   
PAST PERFORMANCE.  Because the fund has been in operation for less than one year
no performance history is provided.

THE HARTFORD BOND INCOME STRATEGY FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Bond Income Strategy Fund seeks a high
level of current income, consistent with a competitive total return, as compared
to bond funds with similar investment objectives and policies, by investing
primarily in debt securities. Debt securities include (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); (3) asset-backed and mortgage-related securities; and (4)
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.
    
 
   
The fund normally invests at least 70% of its portfolio in investment grade
fixed income securities. The fund may invest up to 30% of its total assets in
securities rated in the highest category of below investment grade bonds ("Ba1",
"Ba2" or "Ba3" by Moody's Investors Service, Inc. or "BB+", "BB" or "BB-" by
Standard & Poor's Corporation), or securities which, if unrated, are determined
by HIMCO to be of comparable quality. Securities rated below investment grade
are commonly referred to as "junk bonds".
    
 
   
The fund invests at least 65% of its total assets in debt securities with a
maturity of at least one year. Although the fund does not have a maximum
maturity term restriction, the fund tends to have an average maturity within the
intermediate-term range. The fund may invest up to 15% of its total assets in
preferred stocks, convertible securities, and securities accompanied by warrants
to purchase equity securities. The fund will not invest in common stocks
directly, but may retain, for reasonable periods of time, common stocks acquired
upon conversion of debt securities or upon exercise of warrants acquired with
debt securities. The fund may invest up to 30% of its total assets in debt
securities of non-U.S. companies.
    
 
   
The fund uses what is sometimes referred to as a top-down analysis to determine
which industries may benefit from current and future changes in the economy. The
fund then selects individual securities that appear comparatively undervalued
within selected industries. The portfolio manager assesses such factors as a
company's business environment, balance sheet, income statement, anticipated
earnings and management team.
    
 
- --------------------------------------------------------------------------------
 
   
MAIN RISKS.  The major factors affecting this fund's performance are interest
rates and credit risk. When interest rates rise, bond prices fall; generally the
longer the fund's maturity, the more sensitive it is to this risk.
    
 
   
The fund could lose money if any bonds it owns are downgraded in credit rating
or go into default. In general, lower-rated bonds have higher credit risks. If
certain sectors or investments don't perform as the fund expects, it could
underperform its peers or lose money.
    
 
   
Junk bonds and foreign securities may make the fund more sensitive to market or
economic shifts in the U.S. and abroad.
    
 
In a down market some of the fund's investments could become harder to value.
 
   
Any U.S. government guarantees on portfolio securities do not apply to the
market value or current yield of the portfolio's securities or to the value of
the fund's shares.
    
 
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable dividends.

PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of a broad-based market index for comparison). The bar chart year-by-year
figures and average annual figures do not include the effect of sales charges as
no sales charge is applicable to the Class Y shares. All figures assume that all
dividends and distributions were reinvested. Keep in mind that past performance
does not indicate future results.

THE HARTFORD MONEY MARKET FUND
- --------------------------------------------------------------------------------
 
   
INVESTMENT GOAL AND STYLE.  The Hartford Money Market Fund seeks maximum current
income consistent with liquidity and preservation of capital. The fund seeks to
maintain a stable share price of $1.00.
    
 
   
The fund focuses on specific short-term money market instruments such as debt
securities issued by corporations and financial institutions which are rated in
the first two investment tiers by at least one nationally recognized statistical
rating organization, or if unrated, determined to be of comparable quality by
HIMCO. 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.
    
 
   
The fund purchases securities which it believes offer attractive returns
relative to the risks undertaken. In addition, the portfolio manager adjusts the
average maturity of the portfolio in anticipation of interest rate changes.

MAIN RISKS.  An investment in the fund is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency. Although
the fund seeks to preserve the value of your investment at $1.00 per share,
there is a risk that the fund's share price could fall below $1.00, which would
reduce the value of your account.

PAST PERFORMANCE.  The bar chart and table below indicate the risks of investing
in the fund. The bar chart shows how the fund's total return has varied from
year to year, while the table shows the fund's performance over time (along with
that of a broad-based market index for comparison). The bar chart year-by-year
figures and average annual figures do not include the effect of sales charges as
no sales charge is applicable to the Class Y shares. All figures assume that all
dividends and distributions were reinvested. Keep in mind that past performance
does not indicate future results.

EXAMPLE.  This example is intended to help you compare the
cost of investing in the fund with the cost of investing
in other mutual funds. The example assumes that you invest
$10,000 in the fund for the time periods indicated and
then redeem all of your shares at the end of those
periods. The example also assumes that your investment has
a 5% return each year, that the fund's operating expenses
remain the same and that you reinvest all dividends and
distributions. Because no sales charges apply to the Class
Y shares you would have the same expenses whether or not
you redeemed your shares. Although your actual costs may
be higher or lower, based on these assumptions your costs
would be:

PRIOR PERFORMANCE OF SIMILAR FUNDS
- --------------------------------------------------------------------------------
 
   
Because the mutual funds that are the subject of this prospectus (the "Retail
Funds") began operations in July, 1996, or later, they have limited operating
and performance histories. However, the Capital Appreciation Fund, International
Opportunities Fund, Stock Fund, Dividend and Growth Fund and Advisers Fund are
modeled after existing funds (the "HLS Funds") that are managed by the same
portfolio managers at HIMCO or Wellington Management and have investment
objectives, policies and strategies substantially similar to those of the
corresponding funds. Depending on the fund involved, similarity of investment
characteristics may involve factors such as industry diversification, country
diversification, portfolio beta, portfolio quality, average maturity of
fixed-income assets, equity/non-equity mixes, and individual holdings. The HLS
Funds are used as investment vehicles for the assets of variable annuity and
variable life insurance contracts issued by The Hartford affiliates.
    
 
   
Below you will find information about the performance of the HLS Funds. Because
the expenses of the HLS Funds are generally lower than the Retail Funds the
performance of the HLS Funds would have been lower had the Retail Fund expenses
been applied.
    
 
The table below sets forth each fund, its corresponding HLS Fund, and their
respective inception date and asset sizes as of December 31, 1998. Any fund's
future performance may be greater or less than the performance of the
corresponding HLS Fund due to, among other things, differences in expenses,
asset sizes and cash flows between a fund and the corresponding HLS Fund.

ADDITIONAL INVESTMENT MATTERS
- --------------------------------------------------------------------------------
 
 USE OF OPTIONS AND FUTURES
 
Each fund (other than the Money Market fund) may purchase and sell options and
enter into futures contracts, in each case with respect to stocks, bonds, groups
of securities (such as financial indices) or foreign currencies. These
techniques permit a fund to gain exposure to a particular security or group of
securities, and thereby earn returns similar to those which would be earned by
direct investments in those securities. These techniques are also used to manage
risk by hedging a fund's portfolio investments. Use of these techniques may
result in losses to a fund or increase volatility.
 
 USE OF MONEY MARKET INVESTMENTS
 FOR TEMPORARY DEFENSIVE PURPOSES
 
From time to time each fund (other than the Money Market fund) may invest some
or all of its assets in high quality money market securities for temporary
defensive purposes in response to adverse market, economic or political
conditions. To the extent a fund is in a defensive position, the fund may lose
the benefit of upswings and limit its ability to meet its investment objective.
 
 ABOUT EACH FUND'S INVESTMENT GOAL
 
Each fund's investment goal may be changed without approval of the shareholders
of the fund. A fund may not be able to achieve its goal.
 TAX CONSEQUENCES OF PORTFOLIO
 TRADING PRACTICES
 
   
At times each fund may engage in short-term trading, which could produce higher
brokerage expenses for a fund and higher taxable distributions to the fund's
shareholders. The funds are not managed to achieve a particular tax result for
shareholders. Shareholders should consult their own tax adviser for individual
tax advice.
    
 
 YEAR 2000
 
   
The services provided to the Funds by HIFSCO, 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. HIFSCO, 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. In addition, to the extent that a
portfolio company suffers from a Year 2000 problem, a fund's performance could
be adversely affected.

TRANSACTION POLICIES
- --------------------------------------------------------------------------------
 
 VALUATION OF SHARES
 
   
The net asset value per share (NAV) for each fund and class is determined each
business day at the close of regular trading on the New York Stock Exchange
("NYSE") (typically 4 P.M. Eastern Time). Except for the Money Market Fund, the
funds use market prices in valuing portfolio securities, but may use fair-value
estimates, as determined in good faith by the Board of Directors, if reliable
market prices are unavailable. The Money Market Fund's assets are valued at
amortized cost.
    
 
   
Trading on many foreign securities markets is completed at various times before
or after the close of the NYSE or on days the NYSE is not open for business.
Consequently, the calculation of a fund's NAV may take place at a time that is
different than when prices are determined for certain foreign securities. As a
result, events affecting the values of foreign portfolio securities that occur
after the close of the NYSE will not be reflected in a fund's calculation of
NAV.
    

 BUY AND SELL PRICES
 
When you buy shares, you pay the NAV. When you sell shares, you receive the NAV.

 EXECUTION OF REQUESTS
 
   
Each fund is open on those days when the New York Stock Exchange is open,
typically Monday through Friday. Buy and sell requests are executed at the next
NAV to be calculated after your request is received by the transfer agent or
authorized broker-dealers and third-party administrators.
    
 
At times of peak activity, it may be difficult to place requests by phone.
During these times, consider sending your request in writing.
 
In unusual circumstances, any fund may temporarily suspend the processing of
sell requests, or may postpone payment of proceeds for up to three business days
or longer, as allowed by federal securities laws.
 TELEPHONE TRANSACTIONS
 
For your protection, telephone requests may be recorded in order to verify their
accuracy. Also for your protection, telephone transactions are not permitted on
accounts whose names or addresses have changed within the past 30 days. Proceeds
from telephone transactions can only be mailed to the address of record.
 EXCHANGES
 
You may exchange shares of one fund for shares of the same class of any other.
The registration for both accounts involved must be identical.
 
   
Each fund reserves the right to refuse or delay exchanges by any person or group
if, in HIMCO's or Wellington Management's judgment, a fund would be unable to
invest the money effectively in accordance with its investment objective and
policies, or would otherwise potentially be adversely affected. Your exchanges
may be restricted or refused if a fund receives or anticipates simultaneous
orders affecting significant portions of the fund's assets. In particular, a
pattern of exchanges that coincides with a "market timing" strategy may be
disruptive to the fund. Although a fund will attempt to give you prior notice
whenever it is reasonably able to do so, it may impose these restrictions at any
time. Each fund reserves the right to terminate or modify the exchange privilege
in the future.
    
 
 CERTIFICATED SHARES
 
Shares are electronically recorded and therefore share certificates are not
issued.
 
 SALES IN ADVANCE OF
 PURCHASE PAYMENTS
 
When you place a request to sell shares for which the purchase money has not yet
been collected, the request will be executed in a timely fashion, but the fund
will not release the proceeds to you until your purchase payment clears. This
may take up to 15 business days after the purchase.
 
 SPECIAL REDEMPTIONS
 
   
Although it would not normally do so, each fund has the right to pay the
redemption price of shares of the fund in whole or in part in portfolio
securities as prescribed by the Directors. When the shareholder sells portfolio
securities received in this fashion, he would incur a brokerage charge. Any such
securities would be valued for the purposes of making such payment at the same
value as used in determining net asset value. The funds have elected to be
governed by Rule 18f-1 under the 1940 Act, pursuant to which each fund is
obligated to redeem shares solely in cash up to the lesser of $250,000 or 1% of
the net asset value of the applicable fund during any 90 day period for any one
account.

 PAYMENT REQUIREMENTS
 
All of your purchases must be made in U.S. dollars and checks must be drawn on
U.S. banks and made payable to The Hartford Mutual Funds, or in the case of a
retirement account, to the custodian or trustee. You may not purchase shares
with a third party check.
 
 DIVIDENDS AND ACCOUNT POLICIES
 
ACCOUNT STATEMENTS  In general, you will receive account statements as follows:
 
- - after every transaction (except a dividend reinvestment) that affects your
  account balances
 
- - after any changes of name or address of the registered owner(s)
 
- - in all other circumstances, every quarter
 
Every year you should also receive, if applicable, a Form 1099 tax information
statement.
 
If you are a participant in an employer-sponsored retirement plan you will
receive statements from your plan administrator.
 
DIVIDENDS  Each fund intends to distribute substantially all of its net income
and capital gains to shareholders at least once a year. Normally, dividends from
net investment income of the Small Company Fund, Capital Appreciation Fund,
MidCap Fund, International Opportunities Fund, Global Leaders Fund and Stock
Fund will be declared and paid annually; dividends from the net investment
income of the Growth and Income Fund, Dividend and Growth Fund and Advisers Fund
will be declared and paid quarterly; dividends from the net investment income of
the Bond Income Strategy Fund and High Yield Fund will be declared and paid
monthly and dividends from net investment income of the Money Market Fund will
be declared daily and paid monthly. Dividends from the Money Market Fund are not
paid on shares until the day following the date on which the shares are issued.
Unless shareholders specify otherwise, all dividends and distributions will be
automatically reinvested in additional full or fractional shares of each fund.
 
   
TAXABILITY OF DIVIDENDS  Dividends you receive from a fund, whether reinvested
or taken as cash, are generally considered taxable. Dividends from a fund's
long-term capital gains are taxable as capital gains; dividends from short-term
capital gains and income are generally taxable as ordinary income. Some
dividends paid in January may be taxable as if they had been paid the previous
December. Tax rates may vary depending on how long a fund investment is held.
See your application for distribution options.
    
 
The Form 1099 that is mailed to you every January details your dividends and
their federal tax category, although you should verify your tax liability with
your tax professional.
 
TAXABILITY OF TRANSACTIONS  Any time you sell or exchange shares, it is
considered a taxable event for you unless the sale or exchange is within a
qualified retirement plan. Depending on the purchase price and the sale price of
the shares you sell or exchange, you may have a gain or a loss on the
transaction. You are responsible for any tax liabilities generated by your
transactions.
 
 ADDITIONAL INVESTOR SERVICES
 
ELECTRONIC TRANSFERS THROUGH AUTOMATED CLEARING HOUSE ("ACH")  allow you to
initiate a purchase or redemption for as little as $100 or as much as $50,000
between your bank account and fund account using the ACH network.
 
If you are a participant in a tax qualified retirement plan, check with your
plan administrator for additional investor services.

ADDITIONAL SHARE CLASSES
- --------------------------------------------------------------------------------
 
In addition to Class Y shares, each fund also offers Class A, Class B and Class
C shares. Class A, Class B and Class C shares are available to individual
investors. Class A, Class B and Class C shares generally have operating expenses
similar to Class Y shares, except for certain sales charges and distribution and
transfer agent fees. Such expenses may affect performance. Please call
1-888-843-7824 for additional information on the purchase of Class A, Class B or
Class C shares.

                               GENERAL INFORMATION
   

         The Hartford Mutual Funds, Inc. (the "Company") is an open-end
management investment company consisting of twelve separate diversified
portfolios (each a "Fund" or together the "Funds"). The Company was organized as
a Maryland Corporation on March 21, 1996. This SAI relates to all twelve Funds.
Hartford Investment Financial Services Company ("HIFSCO") is the investment
manager to each Fund. HIFSCO is an indirect majority owned subsidiary of The
Hartford Financial Services Group, Inc. ("The Hartford"), an insurance holding
company with over $130 billion in assets. In addition, Wellington Management
Company ("Wellington Management") and The Hartford Investment Management Company
("HIMCO(R)") provide the day-to-day investment management of the Funds.
    

                       INVESTMENT OBJECTIVES AND POLICIES

A.       FUNDAMENTAL RESTRICTIONS OF THE FUNDS

         Each Fund has adopted the following fundamental investment restrictions
which may not be changed without approval of a majority of the applicable 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 a 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 and investment strategies of each Fund are set
forth in the Prospectus. Set forth below are the fundamental investment policies
applicable to each Fund followed by the non-fundamental policies applicable to
each Fund.

         Each 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.

         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

                                       -3-
<PAGE>   115
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, except to the extent that in connection with
the disposition of portfolio securities, a Fund may be deemed to be an
underwriter for purposes of the Securities Act of 1933 (the "1933 Act").

         4. Purchase or sell real estate, except that a 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 a 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 a 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, each Fund will operate as a "diversified" fund within the
meaning of the 1940 Act. This means that with respect to 75% of a Fund's total
assets, a 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.

                                       -4-
<PAGE>   116
         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 a 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 Funds in certain states,
the Board of Directors may, in its sole discretion, adopt restrictions on
investment policy 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 a 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 FUNDS.

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

         Each Fund may not:

         1.   Pledge, mortgage or hypothecate its assets, except to the extent
required to secure permitted borrowings. This investment restriction shall not
apply to any required segregated account or securities lending arrangements. The
deposit of underlying securities and other assets in escrow and collateral
arrangements with respect to margin for futures contracts and related options is
not deemed to be a pledge or other encumbrance.

         2.   Purchase any securities on margin (except that a Fund may obtain
such short-term credits as may be necessary for the clearance of purchases and
sales of portfolio securities) or make short sales of securities (except short
sales against the box) or maintain a short position. The deposit or payment by a
Fund of initial or maintenance margin in connection with futures contracts or
related options transactions is not considered the purchase of a security on
margin.

         3.   Purchase securities which are illiquid if, as a result of any such
purchase, more than 15% of its net assets (10% for the Money Market Fund) would
consist of such securities.

         4.   Purchase securities while outstanding borrowings exceed 5% of a
Fund's total assets.

         5.   Purchase interests in oil, gas, or other mineral exploration
programs or mineral leases; however, this policy will not prohibit the
acquisition of securities of companies engaged in the production or transmission
of oil, gas, or other minerals.

                                       -5-
<PAGE>   117
         6.   Invest for the purpose of exercising control over or management of
any company.

         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 a Fund's assets will not
be considered a violation of the restriction.

MISCELLANEOUS INVESTMENT STRATEGIES AND RISKS

         A further description of certain investment strategies of each Fund is
set forth below. The percentage limits described in the sections below are based
on market value and are determined as of the time securities are purchased.

MONEY MARKET INSTRUMENTS AND TEMPORARY INVESTMENT STRATEGIES

         In addition to the Money Market Fund which may hold cash and invest in
money market instruments at any time, all other Funds may hold cash and invest
in high quality money market instruments under appropriate circumstances as
determined by HIMCO or Wellington Management. Such Funds may invest up to 100%
of their 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

   
         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 a Fund to the seller.
The resale price would be in excess of the purchase price, reflecting an agreed
upon market interest rate.
    

         Each Fund is permitted to enter into fully collateralized repurchase
agreements. The Company'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 HIMCO and Wellington Management's compliance with such standards.
Presently, each Fund may enter into repurchase agreements only with commercial
banks with at least $1 billion in primary capital or with recognized government
securities dealers with a minimum net capital of $100 million.

                                       -6-
<PAGE>   118
         HIMCO or 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.
   
    

REVERSE REPURCHASE AGREEMENTS

         Each Fund may also enter into reverse repurchase agreements. Reverse
repurchase agreements involve sales by a Fund of portfolio assets concurrently
with an agreement by a 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 a Fund is obligated to repurchase may decline below the
repurchase price. A reverse repurchase agreement is viewed as a collateralized
borrowing by a Fund. Borrowing magnifies the potential for gain or loss on the
portfolio securities of a Fund and, therefore, increases the possibility of
fluctuation in a Fund's net asset value. A Fund will establish a segregated
account with the Company's custodian bank in which a Fund will maintain cash,
cash equivalents, U.S. government securities or other high quality debt
securities equal in value to a Fund's obligations in respect of reverse
repurchase agreements. A 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 particular Fund equals more than
33-1/3% of the value the Fund's total assets.

DEBT SECURITIES

         Each 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); (3) asset-backed securities (Advisers
Fund, High Yield Fund, Bond Income Strategy Fund and Money Market Fund only) and
mortgage-related securities, including collateralized mortgage obligations
("CMO's") (Advisers Fund, High Yield Fund and Bond Income Strategy Fund only);
and (4) 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

         Each 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 HIMCO or Wellington Management). These securities are generally referred to
as "investment grade securities." Each rating category has within it different
gradations or sub-categories. If a 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

                                       -7-
<PAGE>   119
that rating category. If a security is downgraded to a rating category which
does not qualify for investment, HIMCO or 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 HIMCO or 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 DEBT SECURITIES

         Each of the Capital Appreciation Fund, MidCap Fund, Growth and Income
Fund, Dividend and Growth Fund, International Opportunities Fund, Global Leaders
Fund, Small Company Fund, Stock Fund, and Advisers Fund is permitted to invest
up to 5% of its assets in fixed income securities rated as low as "C" by Moody's
or "CC" by S&P or of comparable quality if not rated. The Bond Income Strategy
Fund is permitted to invest up to 30% of its assets in securities rated in the
highest level below investment grade (i.e., "Ba" for Moody's or "BB" by S&P), or
if unrated, securities determined to be of comparable quality by HIMCO. Although
the High Yield Fund is permitted to invest up to 100% of its total assets in
securities rated below investment grade, no more than 10% of total assets will
be invested in securities rated below B3 by Moody's or B- by S&P, or if unrated,
determined to be of comparable quality by HIMCO. Securities rated below
investment grade are commonly referred to as "high yield-high risk debt
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 a 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.
Descriptions of the debt securities ratings system, including their speculative
characteristics attributable to each ratings category, are set forth as an
appendix to this SAI. 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 a
Fund with a commensurate effect on the value of a Fund's shares. If a security
is downgraded to a rating category which does not qualify for investment, HIMCO
or 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.

MORTGAGE-RELATED SECURITIES

         The mortgage-related securities in which the Advisers Fund, High Yield
Fund and Bond Income Strategy Fund may invest include interests in pools of
mortgage loans made by lenders

                                       -8-
<PAGE>   120
such as savings and loan institutions, mortgage bankers, commercial banks and
others. Pools of mortgage loans are assembled for sale to investors (such as the
Funds) by various governmental, government-related and private organizations.
These Funds may also invest in similar mortgage-related securities which provide
funds for multi-family residences or commercial real estate properties.

         The value of these securities may be significantly affected by interest
rates, the market's perception of the issuers and the creditworthiness of the
parties involved. These securities may also be subject to prepayment risk. The
yield characteristics of the mortgage securities differ from those of
traditional debt securities. Among the major differences are that interest and
principal payments are made more frequently on mortgage securities, usually
monthly, and that principal may be prepaid at any time because the underlying
mortgage loans or other assets generally permit prepayment at any time.
Evaluating the risks associated with prepayment and determining the rate at
which prepayment is influenced by a variety of economic, geographic,
demographic, social and other factors including interest rate levels, changes in
housing needs, net equity built by mortgagors in the mortgaged properties, job
transfers, and unemployment rates. If a Fund purchases these securities at a
premium, a prepayment rate that is faster than expected will reduce yield to
maturity, while a prepayment rate that is slower than expected will have the
opposite effect of increasing yield to maturity. Conversely, if a Fund purchases
these securities at a discount, faster than expected prepayments will increase,
while slower than expected prepayments will reduce, yield to maturity. Amounts
available for reinvestment are likely to be greater during a period of declining
interest rates and, as a result, are likely to be reinvested at lower interest
rates than during a period of declining interest rates and, as a result, are
likely to be reinvested at lower interest rates than during a period of rising
interest rates. Accelerated prepayments on securities purchased by a Fund at a
premium also impose a risk of loss of principal because the premium may not have
been fully amortized at the time the principal is repaid in full.

         The mortgage securities in which each Fund invests differ from
conventional bonds in that principal is paid back over the life of the mortgage
securities rather than at maturity. As a result, the holder of the mortgage
securities (i.e., a Fund) receives monthly scheduled payments of principal and
interest, and may receive unscheduled principal payments representing
prepayments on the underlying mortgages. When the holder reinvests the payments
and any unscheduled prepayments of principal it receives, it may receive a rate
of interest which is lower than the rate on the existing mortgage securities.
For this reason, mortgage securities are less effective than other types of U.S.
Government securities as a means of "locking in" long-term interest rates. See
"Illiquid Securities."

         Up to 25% of the value of the Bond Income Strategy Fund's total assets
may be applied to mortgage dollar roll transactions. In a mortgage dollar roll a
fund sells mortgage-backed securities for delivery in the current month and
simultaneously contracts to repurchase substantially similar (same type, coupon
and maturity) securities on a specified future date. The Fund will engage in
"covered rolls" or, if not covered, the Fund will establish a segregated account
with the Company's custodian consisting of cash, U.S. Government securities and
other liquid, high quality

                                       -9-
<PAGE>   121
debt securities. A "covered roll" is a specific type of dollar roll for which
there is an offsetting cash position or a cash equivalent security position
which matures on or before the forward settlement date of the dollar roll
transaction.

ASSET-BACKED SECURITIES

         The Advisers Fund, High Yield Fund, Bond Income Strategy Fund and Money
Market Fund may invest in asset-backed securities. The securitization techniques
used for asset-backed securities are similar to those used for mortgage-related
securities. The collateral for these securities has included home equity loans,
automobile and credit card receivables, boat loans, computer leases, airplane
leases, mobile home loans, recreational vehicle loans and hospital accounts
receivables. These Funds may invest in these and other types of asset-backed
securities that may be developed in the future. These securities may be subject
to the risk of prepayment or default. The ability of an issuer of asset-backed
securities to enforce its security interest in the underlying securities may be
limited.

EQUITY SECURITIES

         Each Fund except the Bond Income Strategy Fund and High Yield Fund as
described below and except the Money Market Fund may invest all or a portion of
their assets in equity securities which include common stocks, preferred stocks
(including convertible preferred stock) and rights to acquire such securities.
In addition, these Funds may invest in securities such as bonds, debentures and
corporate notes which are convertible into common stock at the option of the
holder. The Bond Income Strategy Fund and High Yield Fund may each invest up to
15% of its total assets in preferred stocks, convertible securities, and
securities carrying warrants to purchase equity securities. The Bond Income
Strategy Fund and High Yield Fund will not invest in common stocks directly, but
may retain, for reasonable periods of time, common stocks acquired upon
conversion of debt securities or upon exercise of warrants acquired with debt
securities.

SMALL CAPITALIZATION SECURITIES

         All Funds except the Money Market Fund may invest in equity securities
of companies with market capitalizations within the range represented by the
Russell 2000 Index ("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. 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.

                                      -10-
<PAGE>   122
NON-U.S. SECURITIES

         Each 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, HIMCO or Wellington Management will
evaluate the economic and political climate and the principal securities markets
of the country in which an issuer is located.

   

         The Small Company, Capital Appreciation, MidCap, Stock, Growth and 
Income, Dividend and Growth, and Advisers Funds are permitted to invest up to
20% of their assets in non-U.S. companies. The Money Market Fund may invest up
to 25% of its assets, the Bond Income Strategy and High Yield Funds are
permitted to invest up to 30% of their assets and the International
Opportunities Fund may invest up to 100% of its assets in such companies. The
Global Leaders Fund invests in at least five countries, one of which is the
United States, however, the fund has no limit on the amount of assets that must
be invested in each country.  
    

         Investing in securities issued by non-U.S. issuers involves
considerations and potential risks not typically associated with investing in
obligations issued by U.S. issuers. Less information may be available about
non-U.S. issuers compared with U.S. issuers. For example, 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. In addition, 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 Funds may invest have 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.

                                      -11-
<PAGE>   123
   
         From time to time, the International Opportunities Fund, Global Leaders
Fund, High Yield Fund and Bond Income Strategy Fund may invest up to 25%, 25%,
30% and 30%, respectively, of their assets in securities of issuers 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. Although the High Yield Fund may invest up to 30% of its assets in
assets of non-U.S. companies, only 10% of such amount may be represented in
non-U.S. currencies.
    

CURRENCY TRANSACTIONS

         Each Fund, except the Money Market 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 a 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 Funds may enter into currency transactions only with
counterparties that HIMCO or Wellington Management deems to be creditworthy.

         The Funds 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 Funds, for cash flow management, and, to
a lesser extent, to enhance returns, each Fund, except the Money Market Fund,
may employ certain hedging, 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

                                      -12-
<PAGE>   124
of prices of equity and debt securities and other financial indices. A Fund's
ability to engage in these practices may be limited by tax considerations and
certain other legal considerations.

         A 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 Funds 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 particular Fund holds in its
portfolio or that it intends to purchase. For example, if a 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 a 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.

   
         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. A 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.
    

         A Fund may write covered options only. "Covered" means that, so long as
a 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. A 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, a 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, a Fund may use foreign currency futures contracts when 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

                                      -13-
<PAGE>   125
   
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 or partially 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 Funds also may purchase call or put options on foreign currency
futures contracts to obtain a fixed foreign exchange rate at limited risk. A
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. A 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. A 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 a 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 a Fund writes a covered option on an
index, a 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 a 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,
options which are currently exercisable may be excluded in computing the 5%
limit. Adoption of this guideline will not limit the percentage of a Fund's
assets at risk to 5%.
    

         Although any one 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

                                      -14-
<PAGE>   126
might not be subject were such strategies not employed. Such risks include: (1)
dependence on the ability of HIMCO or 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 a 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 a 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 a 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 a Fund
would have been in a better position had it not used such a strategy at all.

SWAP AGREEMENTS

         Each Fund, except the Money Market 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 a Fund's investment exposure from
one type of investment to another. For example, if a 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 a Fund's
investments and its share price and yield.

                                      -15-
<PAGE>   127
         The Funds will usually enter into interest rate swaps on a net basis,
i.e., where the two parties make net payments with a Fund receiving or paying,
as the case may be, only the net amount of the two payments. The net amount of
the excess, if any, of a 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 Company's custodian in a segregated
account. If a 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 HIMCO or 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, a 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 a Fund will be able to enter into interest rate swaps or to
purchase interest rate caps, collars or floors at prices or on terms HIMCO or
Wellington Management, as appropriate, believes are advantageous to such Fund.
In addition, although the terms of interest rate swaps, caps, collars and floors
may provide for termination, there can be no assurance that a 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. Interest rate swaps, caps, collars and
floors are considered by the SEC to be illiquid securities.

         The successful utilization of hedging and risk management transactions
requires skills different from those needed in the selection of a Fund's
portfolio securities and depends on HIMCO's or Wellington Management's ability
to predict correctly the direction and degree of movements in interest rates.
Although the Funds believe that use of the hedging and risk management
techniques described above will benefit the Funds, if HIMCO's or Wellington
Management's judgment about the direction or extent of the movement in interest
rates is incorrect, a Fund's overall performance would be worse than if it had
not entered into any such transactions. For example, if a 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, such 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.

                                      -16-
<PAGE>   128
ILLIQUID SECURITIES

         Each Fund is permitted to invest in illiquid securities. No illiquid
securities will be acquired if upon the purchase more than 10% of Money Market
Fund's net assets or 15% of each other 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 business within seven days at
approximately the price used to determine a Fund's net asset value. Each 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. A Fund may
not be able to sell illiquid securities when HIMCO or 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 a 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 a Fund may invest that are not readily marketable.

WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES

         Each 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 Funds generally
purchase securities on a when-issued basis with the intention of acquiring the
securities, the Funds may sell the securities before the settlement date if
HIMCO or Wellington Management deems it advisable. At the time a 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. A 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 a Fund will segregate securities sold on a
delayed-delivery basis.

<PAGE>   129
OTHER INVESTMENT COMPANIES

         Each Fund is permitted to invest in other investment companies. The
investment companies in which a Fund would invest may or may not be registered
under the 1940 Act. Securities in certain countries are currently accessible to
the Funds only through such investments. The investment in other investment
companies is limited in amount by the 1940 Act, and will involve the indirect
payment of a portion of the expenses, including advisory fees, of such other
investment companies. Under the 1940 Act, a 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 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

         Each of the Funds 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 respective Fund. While
the securities are on loan the borrower will pay the respective 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 Funds may lend securities only if: (1) each loan is fully secured by
appropriate collateral at all times; and (2) the value of all loaned securities
of any Fund is not more than 33-1/3% of the Fund's total assets taken at the
time of the loan (including collateral received in connection with any loans).

         The shares of the Funds are entitled to vote separately to approve
investment advisory agreements or changes in investment restrictions, but
shareholders of all series vote together in the election and selection of
Directors and accountants. Shares of a Fund vote together as a class on matters
that affect the Fund in substantially the same manner. Matters pertaining only
to one or more Funds will be voted upon only by those Funds. As to matters
affecting a single class, shares of such class will vote separately. Shares of
the Funds do not have cumulative voting rights. The Company and the Funds 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. Each Fund's shares are fully paid, and
nonassessable and, when issued, have no preference, preemptive, conversion or
similar rights and are freely transferable.

         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 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 ADVISORY ARRANGEMENTS

         The Company, on behalf of each Fund, has entered into an investment
management agreement with HIFSCO. The investment management agreement provides
that HIFSCO, subject to the supervision and approval of the Company's Board of
Directors, is responsible for the management of each Fund. In addition, HIFSCO
provides administrative personnel, services, equipment and facilities and office
space for proper operation of the Company. Although HIFSCO has agreed to arrange
for the provision of additional services necessary for the proper operation of
the Company, each Fund pays for these services directly.

         With respect to the Small Company Fund, Capital Appreciation Fund,
MidCap Fund, International Opportunities Fund, Global Leaders Fund, Stock Fund,
Growth and Income Fund, Dividend and Growth Fund and Advisers Fund, HIFSCO has
entered into a investment subadvisory 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
HIFSCO, is responsible for (among other things) the day-to-day investment and
reinvestment of the assets of such Funds and furnishing each such Fund with
advice and recommendations with respect to investments and the purchase and sale
of appropriate securities for each Fund. With respect to the High Yield Fund,
Bond Income Strategy Fund and Money Market Fund, HIFSCO has entered into an
investment services agreement with HIMCO for the provision of the day-to-day
investment management services.

   
         As provided by the investment management agreement, each Fund pays
HIFSCO an investment management fee, which is accrued daily and paid monthly,
equal on an annual basis to a stated percentage of the respective Fund's average
daily net asset value. HIFSCO, not any Fund, pays the subadvisory fees to
Wellington Management and HIMCO.
    

         No person other than HIMCO or Wellington Management and their directors
and employees regularly furnishes advice to the Funds with respect to the
desirability of the Funds investing in, purchasing or selling securities. HIMCO
and Wellington Management may from time 

                                      -28-
<PAGE>   140
to time receive statistical or other information regarding general economic
factors and trends, from The Hartford and its affiliates.

         Securities held by any Fund may also be held by other funds and other
clients for which HIMCO, Wellington Management or their respective affiliates
provide investment advice. Because of different investment objectives or other
factors, a particular security may be bought by HIMCO or 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 HIMCO or
Wellington Management act as an investment adviser, (including the Funds
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. To the extent that transactions on behalf of more than one
client of HIMCO, Wellington Management or their 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.

   
         Each Fund has paid the following advisory fees based on a percentage
of assets:

                            DISTRIBUTION ARRANGEMENTS

         Hartford Investment Financial Services Company ("HIFSCO") serves as the
principal underwriter for each Fund pursuant to an Underwriting Agreement
initially approved by the Board of Directors of the Company. HIFSCO is a
registered broker-dealer and member of the National Association of Securities
Dealers, Inc. (NASD). Shares of each Fund are continuously offered and sold by
selected broker-dealers who have executed selling agreements with HIFSCO. Except
as discussed below under Distribution Plans, HIFSCO bears all the expenses of
providing services pursuant to the Underwriting Agreement including the payment
of the expenses relating to the distribution of Prospectuses for sales purposes
as well as any advertising or sales literature. The Fund bears the expenses of
registering its shares with the SEC and qualifying them with state regulatory
authorities. The Underwriting Agreement continues in effect for two years from
initial approval and for successive one-year periods thereafter, provided that
each such continuance is specifically approved (i) by the vote of a majority of
the Directors of the Company, including a majority of the Directors who are not
parties to the Underwriting Agreement or interested persons of any such party,
(as the term interested person is defined in the 1940 Act); or (ii) by the vote
of a majority of the outstanding voting securities of a Fund. HIFSCO is not
obligated to sell any specific amount of shares of any Fund.

         HIFSCO and its affiliates pay, out of their own assets, compensation to
brokers, financial institutions and other persons for the sale and distribution
of the Company's shares and/or for the servicing of those shares. These payments
("Additional Payments") are in addition to sales commissions reallowed to
dealers. These Additional Payments may take the form of "due diligence" payments
for a broker's examination of the Funds and payments for providing extra
employee training and information relating to the Funds; "listing" fees for the
placement of the Funds on a dealer's list of mutual funds available for purchase
by its customers; "finders" or "referral" fees for directing investors to the
Funds; "marketing support" fees for providing assistance in promoting the sale
of the Funds' shares; and payments for the sale of shares and/or the maintenance
of share balances. In addition, HIFSCO and its affiliates make Additional
Payments for subaccounting, administrative and/or shareholder processing
services that are in addition to the shareholder servicing and processing fees
paid by the Funds. The Additional Payments may be a fixed dollar amount, may be
based on the number of customer accounts maintained by a broker or financial
institution, or may be based on a percentage of the value of shares sold to, or
held by, customers of the brokers or financial institutions involved.
Furthermore, and subject to NASD regulations, HIFSCO and its affiliates may
contribute to various non-cash and cash incentive arrangements to promote the
sale of shares, as well as sponsor various educational programs, sales contests
and/or promotions in which participants may receive prizes such as travel
awards, merchandise and cash and/or investment research pertaining to particular
securities and other financial instruments or to the securities and financial
markets generally, educational information and related support materials and
hardware and/or software. HIFSCO and its affiliates may also pay for the travel
expenses, meals, lodging and entertainment of brokers or financial institutions
and their salespersons and guests in connection with education, sales and
promotional programs, subject to applicable NASD regulations. These programs,
which 

                                      -32-
<PAGE>   144
may be different for different broker-dealers or financial institutions, will
not change the price an investor will pay for shares or the amount that a fund

         The Class A shares of the Money Market Fund do not collect an up-front
sales charge.

         The distributor may pay up to the entire amount of the sales commission
to particular broker-dealers. The distributor may pay dealers of record
commissions on purchases over $1 million an amount up to the sum of 1.0% of the
first $2.5 million, plus 0.50% of the next $2.5 million, plus 0.25% of share
purchases over $5 million. In addition, the distributor may provide compensation
to dealers of record for shares purchased without a sales charge.

         The distributor pays commissions to dealers of up to 4% of the purchase
price of Class B shares purchased through dealers and pays commissions to
dealers of up to 2% of the purchase price of Class C shares purchased through
dealers.

         HIFSCO's principal business address is 200 Hopmeadow Street, Simsbury,
Connecticut 06070. HIFSCO was organized as a Delaware Corporation on December 9,
1996 and is an indirect wholly-owned subsidiary of The Hartford.

                               DISTRIBUTION PLANS

         The Company has adopted separate distribution plans (the "Plans") for
Class A, Class B and Class C shares of each Fund pursuant to appropriate
resolutions of the Company's Board of Directors in accordance with the
requirements of Rule 12b-1 under the 1940 Act and the requirements of the
applicable rule of the NASD regarding asset based sales charges.

                                      -34-
<PAGE>   146
         CLASS A PLAN

         Pursuant to the Class A Plan, a Fund may compensate HIFSCO for its
expenditures in financing any activity primarily intended to result in the sale
of Fund shares and for maintenance and personal service provided to existing
Class A shareholders. The expenses of a Fund pursuant to the Class A Plan are
accrued on a fiscal year basis and may not exceed, with respect to the Class A
shares of each Fund, the annual rate of 0.35% of the Fund's average daily net
assets attributable to Class A shares. Up to 0.25% of the fee may be used for
shareholder servicing expenses with the remainder used for distribution
expenses. All or any portion of this fee may be remitted to brokers who provide
distribution or shareholder account services.

         CLASS B PLAN

         Pursuant to the Class B Plan, a Fund may pay HIFSCO a fee of up to
1.00% of the average daily net assets attributable to Class B shares, 0.75% of
which is a fee for distribution financing activities and 0.25% of which is for
shareholder account services. All or any portion of such fees may be remitted to
brokers who assist in the distribution of Class B shares or provide maintenance
and personal services to existing Class B shareholders. HIFSCO will advance to
dealers the first-year service fee at a rate equal to 0.25% of the amount
invested. As compensation for such advance, HIFSCO may retain the service fee
paid by a Fund with respect to such shares for the first year after purchase.
Dealers will become eligible for additional service fees with respect to such
shares commencing in the thirteenth month following purchase. Brokers may from
time to time be required to meet certain other criteria in order to receive
service fees. HIFSCO or its affiliates are entitled to retain all service fees
payable under the Class B Plan for which there is no dealer of record or for
which qualification standards have not been met as partial consideration for
personal services and/or account maintenance services performed by HIFSCO or its
affiliates for shareholder accounts. The Class B Plan also provides that HIFSCO
will receive all contingent deferred sales charges attributable to Class B
shares.

         CLASS C PLAN

         Pursuant to the Class C Plan, a Fund may pay HIFSCO a fee of up to
1.00% of the average daily net assets attributable to Class C shares, 0.75% of
which is a fee for distribution financing activities and 0.25% of which is for
shareholder account services. All or any portion of such fees may be remitted to
brokers who assist in the distribution of Class C shares or provide maintenance
and personal services to existing Class C shareholders. HIFSCO will advance to
dealers the first-year service fee at a rate equal to 0.25% of the amount
invested. As compensation for such advance, HIFSCO may retain the service fee
paid by a Fund with respect to such shares for the first year after purchase.
Dealers will become eligible for additional service fees with respect to such
shares commencing in the thirteenth month following purchase. Brokers may from
time to time be required to meet certain other criteria in order to receive
service fees. HIFSCO or its affiliates are entitled to retain all service fees
payable under the Class C Plan for which there is no dealer of record or for
which qualification standards have not been met as partial

                                      -35-
<PAGE>   147
consideration for personal services and/or account maintenance services
performed by HIFSCO or its affiliates for shareholder accounts. The Class C Plan
also provides that HIFSCO will receive all contingent deferred sales charges
attributable to Class C shares.

         GENERAL

         Distribution fees paid to HIFSCO may be spent on any activities or
expenses primarily intended to result in the sale of the Company's shares
including (a) payment of initial and ongoing commissions and other payments to
brokers, dealers, financial institutions or others who sell each Fund's shares;
(b) compensation to employees of the Distributor; (c) compensation to and
expenses, including overhead such as communications and telephone, training,
supplies, photocopying and similar types of expenses, of HIFSCO incurred in the
printing and mailing or other dissemination of all prospectuses and statements
of additional information; (d) the costs of preparation, printing and mailing of
reports used for sales literature and related expenses, advertisements and other
distribution-related expenses (including personnel of HIFSCO) and for the
provision of personal service and/or the maintenance of shareholder accounts.
These plans are considered compensation type plans which means HIFSCO is paid
the agreed upon fee regardless of HIFSCO's expenditures.

         In accordance with the terms of the Plans, HIFSCO provides to each
Fund, for review by the Company's Board of Directors, a quarterly written report
of the amounts expended under the respective Plans and the purpose for which
such expenditures were made. In the Board of Directors' quarterly review of the
Plans, they will review the level of compensation the Plans provide in
considering the continued appropriateness of the Plans.

         The Plans were adopted by a majority vote of the Board of Directors,
including at least a majority of Directors who are not, and were not at the time
they voted, interested persons of the Fund as defined in the 1940 Act and do not
and did not have any direct or indirect financial interest in the operation of
the Plans, cast in person at a meeting called for the purpose of voting on the
Plans. In approving the Plans, the Directors identified and considered a number
of potential benefits which the Plans may provide including the potential to
increase assets in order to benefit from economics of scale. The Board of
Directors believes that there is a reasonable likelihood that the Plans will
benefit each Fund and its current and future shareholders. Under their terms,
the Plans remain in effect from year to year provided such continuance is
approved annually by vote of the Directors in the manner described above. The
Plans may not be amended to increase materially the amount to be spent for
distribution without approval of the shareholders of the Fund affected thereby,
and material amendments to the Plans must also be approved by the Board of
Directors in the manner described above. A Plan may be terminated at any time,
without payment of any penalty, by vote of the majority of the Directors who are
not interested persons of the Fund and have no direct or indirect financial
interest in the operations of the Plan, or by a vote of a "majority of the
outstanding voting securities" (as defined in the 1940 Act) of the Fund affected
thereby. A Plan will automatically terminate in the event of its assignment (as
defined in the 1940 Act).

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

         The Company 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 the Board of Directors and HIFSCO, HIMCO and Wellington
Management are primarily responsible for the investment decisions of each Fund
and the placing of its portfolio transactions. In placing orders, it is the
policy of each 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 HIMCO and Wellington
Management generally seek reasonably competitive spreads or commissions, the
Funds will not necessarily be paying the lowest possible spread or commission.
Upon instructions from the Funds, HIMCO and Wellington Management may direct
brokerage transactions to broker/dealers who also sell shares of the Funds.

         HIMCO and 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. Portfolio
securities in the Money Market Fund normally are purchased directly from, or
sold directly to, the issuer, an underwriter or market maker for the securities.
There usually will be no brokerage commissions paid by the Money Market Fund for
such purchases or sales.

         While HIMCO and Wellington Management (as applicable) seek to obtain
the most favorable net results in effecting transactions in a Fund's portfolio
securities, dealers who provide supplemental investment research to HIMCO or
Wellington Management may receive orders for transactions from HIMCO or
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 HIMCO or Wellington Management, a Fund
will be benefited by such supplemental research services, HIMCO and Wellington
Management are 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 HIMCO and Wellington Management under the investment advisory
agreement or the sub-investment advisory agreement. The expenses of HIMCO and
Wellington Management will not necessarily be reduced as a result of the receipt
of such supplemental information. HIMCO and Wellington Management may use such
supplemental research in providing investment advice to portfolios other than
those for which the transactions are made. Similarly, the Funds may benefit from
such research obtained by HIMCO and Wellington Management for portfolio
transactions for other clients.

         Investment decisions for the Funds will be made independently from
those of any other clients that may be (or in the future may be) managed by
HIMCO, Wellington Management or their affiliates. If, however, accounts managed
by HIMCO or Wellington Management are simultaneously engaged in the purchase of
the same security, then, pursuant to general authorization of the Company's
Board of Directors, available securities may be allocated to each Fund or other
client account and may be averaged as to price in whatever manner HIMCO or

                                      -38-
<PAGE>   150
Wellington Management deems to be fair. Such allocation and pricing may affect
the amount of brokerage commissions paid by each Fund. In some cases, this
system might adversely affect the price paid by a Fund (for example, during
periods of rapidly rising or falling interest rates) or limit the size of the
position obtainable for a Fund (for example, in the case of a small issue).

         Although the rules 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 funds.

                        DETERMINATION OF NET ASSET VALUE

         The net asset value of the shares of each Fund is determined by
Hartford Life Insurance Company, ("Hartford Life") an affiliate of The Hartford,
in the manner described in the Funds' Prospectus. The Funds will be closed for
business and will not price their 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, Christmas Day and other holidays
observed by the New York Stock Exchange. Securities held by each Fund other than
the Money Market 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. Short-term securities held
in the Money Market Fund are valued at amortized cost or original cost plus
accrued interest receivable, both of which approximate market value. All other
Funds' 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 Funds' Board of Directors.

         The net asset value per share of the Money Market Fund is determined by
using the amortized cost method of valuing its portfolio instruments. Under the
amortized cost method of valuation, an instrument is valued at cost and the
interest payable at maturity upon the instrument

                                      -39-
<PAGE>   151
is accrued as income, on a daily basis, over the remaining life of the
instrument. Neither the amount of daily income nor the net asset value is
affected by unrealized appreciation or depreciation of the portfolio's
investments assuming the instrument's obligation is paid in full on maturity. In
periods of declining interest rates, the indicated daily yield on shares of the
portfolio computed using amortized cost may tend to be higher than a similar
computation made using a method of valuation based upon market prices and
estimates. In periods of rising interest rates, the indicated daily yield on
shares of the portfolio computed using amortized cost may tend to be lower than
a similar computation made using a method of valuation based upon market prices
and estimates. For all Funds, securities with remaining maturities of less than
60 days are valued at amortized cost, which approximates market value.

         The amortized cost method of valuation permits the Money Market Fund to
maintain a stable $1.00 net asset value per share. The Company's Board of
Directors periodically reviews the extent of any deviation from the $1.00 per
share value that would occur if a method of valuation based on market prices and
estimates were used. In the event such a deviation would exceed one-half of one
percent, the Board of Directors will promptly consider any action that
reasonably should be initiated to eliminate or reduce material dilution or other
unfair results to shareholders. Such action may include selling portfolio
securities prior to maturity, not declaring earned income dividends, valuing
portfolio securities on the basis of current market prices, if available, or, if
not available, at fair market value as determined in good faith by the Board of
Directors, and (considered highly unlikely by management of the Company)
redemption of shares in kind (i.e., portfolio securities).

         A Fund's maximum offering price per Class A share is determined by
adding the maximum sales charge to the net asset value per share. A Fund's
offering price per Class C share is determined by adding the initial sales
charge to the net asset value per share. Class B, Class Y shares and the Class A
shares of the Money Market Fund are offered at net asset value without the
imposition of an initial sales charge.

                        PURCHASE AND REDEMPTION OF SHARES

         For information regarding the purchase of Fund shares, see "About Your
Account -- Buying Shares" in the Funds' Prospectus.

         For a description of how a shareholder may have a Fund redeem his/her
shares, or how he/she may sell shares, see "About Your Account -- Selling
Shares" in the Funds' Prospectus.

         RIGHTS OF ACCUMULATION. Each Fund offers to all qualifying investors
Rights of Accumulation under which investors are permitted to purchase Class A
shares of any Funds of the Company at the price applicable to the total of (a)
the dollar amount then being purchased plus (b) an amount equal to the then
current net asset value of the purchaser's holdings of all shares of any Funds
of the Company and the current account value of the Director variable annuity or
variable life contracts issued by affiliates of The Hartford. For purposes of
the rights of accumulation 

                                      -40-
<PAGE>   152
program, the purchaser may include all shares owned by family members. A family
member is a spouse, parent, grandparent, child, grandchild, brother, sister,
step-family members and in-laws. Acceptance of the purchase order is subject to
confirmation of qualification. The rights of accumulation may be amended or
terminated at any time as to subsequent purchases. The Transfer Agent must be
notified by you or your broker each time a qualifying purchase is made.

         LETTER OF INTENT. Any person may qualify for a reduced sales charge on
purchases of Class A shares made within a thirteen-month period pursuant to a
Letter of Intent (LOI). Class A shares acquired through the reinvestment of
distributions do not constitute purchases for purposes of the LOI. A Class A
shareholder may include, as an accumulation credit towards the completion of
such LOI, the value of all shares of all Funds of the Company owned by the
shareholder. Such value is determined based on the public offering price on the
date of the LOI. During the term of an LOI, Boston Financial Data Services, Inc.
("BFDS"), the Company's transfer agent will hold shares in escrow to secure
payment of the higher sales charge applicable for shares actually purchased if
the indicated amount on the LOI is not purchased. Dividends and capital gains
will be paid on all escrowed shares and these shares will be released when the
amount indicated on the LOI has been purchased. An LOI does not obligate the
investor to buy or the Fund to sell the indicated amount of the LOI. If a Class
A shareholder exceeds the specified amount of the LOI and reaches an amount
which would qualify for a further quantity discount, a retroactive price
adjustment will be made at the time of the expiration of the LOI. The resulting
difference in offering price will purchase additional Class A shares for the
shareholder's account at the applicable offering price. If the specified amount
of the LOI is not purchased, the shareholder shall remit to BFDS an amount equal
to the difference between the sales charge paid and the sales charge that would
have been paid had the aggregate purchases been made at a single time. If the
Class A shareholder does not within twenty days after a written request by BFDS
pay such difference in sales charge, BFDS will redeem an appropriate number of
escrowed shares in order to realize such difference. The Letter of Intent may be
backdated up to 90 days. Additional information about the terms of the Letter of
Intent are available from your registered representative or from BFDS at
1-888-843-7824.

         SYSTEMATIC WITHDRAWAL PLAN. The Systematic Withdrawal Plan ("SWP") is
designed to provide a convenient method of receiving fixed payments at regular
intervals only from Class A shares and Money Market Fund shares not subject to a
CDSC (except as noted below) of a Fund deposited by the applicant under this
SWP. The applicant must deposit or purchase for deposit shares of the Fund
having a total value of not less than $5,000. Periodic checks of $50 per Fund or
more will be sent to the applicant, or any person designated by him, monthly or
quarterly. SWP's for Class B and Class C shares of a Fund and any Money Market
Fund shares subject to a CDSC are permitted only for redemptions limited to no
more than 12% of the original value of the account per year.

         Any income dividends or capital gains distributions on shares under the
SWP will be credited to the SWP account on the payment date in full and
fractional shares at the net asset value per share in effect on the record date.

                                      -41-
<PAGE>   153
         SWP payments are made from the proceeds of the redemption of shares
deposited in a SWP account. Redemptions are potentially taxable transactions to
shareholders. To the extent that such redemptions for periodic withdrawals
exceed dividend income reinvested in the SWP account, such redemptions will
reduce and may ultimately exhaust the number of shares deposited in the SWP
account. In addition, the amounts received by a shareholder cannot be considered
as an actual yield or income on his or her investment because part of such
payments may be a return of his or her capital.

         The SWP may be terminated at any time (1) by written notice to the Fund
or from the Fund to the shareholder; (2) upon receipt by the Fund of appropriate
evidence of the shareholder's death; or (3) when all shares under the SWP have
been redeemed. The fees of the Fund for maintaining SWPs are paid by the Fund.

         Special Redemptions. Although it would not normally do so, each Fund
has the right to pay the redemption price of shares of the Fund in whole or in
part in portfolio securities as prescribed by the Directors. When the
shareholder sells portfolio securities received in this fashion, he would incur
a brokerage charge. Any such securities would be valued for the purposes of
making such payment at the same value as used in determining net asset value.
The Funds have elected to be governed by Rule 18f-1 under the 1940 Act, pursuant
to which each Fund is obligated to redeem shares solely in cash up to the lesser
of $250,000 or 1% of the net asset value of the applicable Fund during any 90
day period for any one account.

DEFERRED SALES CHARGE ON CLASS B AND CLASS C SHARES

         Investments in Class B and Class C shares are purchased at net asset
value per share without the imposition of an initial sales charge so that the
Fund will receive the full amount of the purchase payment.

         Class B and Class C shares which are redeemed within six years or one
year of purchase, respectively, will be subject to a CDSC at the rates set forth
in the Prospectus as a percentage of the dollar amount subject to the CDSC. The
charge will be assessed on an amount equal to the lesser of the current market
value or the original purchase cost of the Class B or Class C shares being
redeemed. No CDSC will be imposed on increases in account value above the
initial purchase prices, including all shares derived from reinvestment of
dividends or capital gains distributions.

         The amount of the CDSC, if any, will vary depending on the number of
years from the time of payment for the purchase of Class B shares until the time
of redemption of such shares. Solely for purposes of determining this number of
years from the time of any payment for the purchases of both Class B and Class C
shares, all payments during a month will be aggregated and deemed to have been
made on the first day of the month.

                                      -42-
<PAGE>   154
         In determining whether a CDSC applies to a redemption, the calculation
will be determined in a manner that results in the lowest possible rate being
charged. It will be assumed that your redemption comes first from shares you
have held beyond the six-year CDSC redemption period for Class B or one year
CDSC redemption period for Class C, or those you acquired through dividend and
capital gain reinvestment, and next from the shares you have held the longest
during the six-year period for Class B shares. For this purpose, the amount of
any increase in a share's value above its initial purchase price is not regarded
as a share exempt from CDSC. Thus, when a share that has appreciated in value is
redeemed during the CDSC period, a CDSC is assessed only on its initial purchase
price.

         When requesting a redemption for a specific dollar amount, please
indicate if you require the proceeds to equal the dollar amount requested. If
not indicated, only the specified dollar amount will be redeemed from your
account and the proceeds will be less any applicable CDSC.

Example:

         You have purchased 100 shares at $10 per share. The second year after
your purchase, your investment's net asset value per share has increased by $2
to $12, and you have gained 10 additional shares through dividend reinvestment.
If you redeem 50 shares at this time your CDSC will be calculated as follows:

<TABLE>

</TABLE>

         *The appreciation is based on all 100 shares in the lot not just the
         shares being redeemed.

         Proceeds from the CDSC are paid to the distributor and are used in
whole or in part by the Funds to defray its expenses related to providing
distribution-related services to the Fund in connection with the sale of the
Class B and Class C shares, such as the payment of compensation to select
selling brokers for selling Class B and Class C shares. The combination of the
CDSC and the distribution and service fees facilitates the ability of the Fund
to sell the Class B and Class C shares without a sales charge being deducted at
the time of the purchase.

         The CDSC will be waived on redemptions of Class B and Class C shares
and of Class A shares that are subject to CDSC, unless indicated otherwise, as
described in the prospectus.

SUSPENSION OF REDEMPTIONS

         A 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 a Fund of securities owned by it is
not reasonably practicable, or (2) it is not reasonably practicable for a Fund
to fairly 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

MONEY MARKET FUND

         In accordance with regulations prescribed by the SEC, the Company is
required to compute the Money Market Fund's current annualized yield for a
seven-day period in a manner which does not take into consideration any realized
or unrealized gains or losses on its portfolio securities. This current
annualized yield is computed by determining the net change (exclusive of
realized gains and losses on the sale of securities and unrealized appreciation
and depreciation) in the value of a hypothetical account having a balance of one
share of the Money Market Fund at the beginning of such seven-day period,
dividing such net change in account value by the value of the account at the
beginning of the period to determine the base period return and annualizing this
quotient on a 365-day basis.

         The SEC also permits the Company to disclose the effective yield of the
Money Market Fund for the same seven-day period, determined on a compounded
basis. The effective yield is calculated by compounding the unannualized base
period return by adding one to the base period return, raising the sum to a
power equal to 365 divided by 7, and subtracting one from the result.

         For the seven-day period ending December 31, 1998, the Money Market
Fund's annualized yield for Class A, Class B, Class C and Class Y shares was
4.26%, 3.57%, 3.54% and 4.72% respectively. For the same period, the effective
yield for Class A, Class B, Class C and Class Y shares was 4.35%, 3.63%, 3.61%
and 4.83% respectively.

         The yield on amounts held in the Money Market Fund normally will
fluctuate on a daily basis. Therefore, the disclosed yield for any given past
period is not an indication or representation of future yields or rates of
return. The Money Market Fund's actual yield is affected by changes in interest
rates on money market securities, average portfolio maturity of the Money Market
Fund, the types and quality of portfolio securities held by the Money Market
Fund, and its operating expenses.

OTHER FUNDS

         STANDARDIZED AVERAGE ANNUAL TOTAL RETURN QUOTATIONS. Average annual
total return quotations for Class A, Class B, Class C and Class Y shares 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

                                                                            hypothetical $1,000 initial payment
T        =    average annual total return                                   made at the beginning of the
                                                                            designated period (or fractional
                                                                            portion thereof)
</TABLE>

         The computation above assumes that all dividends and distributions made
by a 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 a Fund, or of a hypothetical investment in a class of a 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.

         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 a class of the Fund.

                                      -45-
<PAGE>   157
         Each 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 charts below set forth certain performance information as of
December 31, 1998 for the Class A, Class B, Class C and Class Y shares of each
Fund, except as noted, which is adjusted to reflect the maximum sales charge and
the account fees of each Class. Past performance is no guarantee and is not
necessarily indicative of future performance of the shares. The actual annual
returns for the shares may vary significantly from the past and future
performance. Investment returns and the value of the shares will fluctuate in
response to market and economic conditions as well as other factors and shares,
when redeemed, may be worth more or less than their original cost. Total returns
are based on capital changes plus reinvestment of all distributions for the time
periods noted in the charts below. Total return of the shares would have been
lower without the expense limitation effected by HIFSCO.

         Each Fund may also publish its distribution rate and/or its effective
distribution rate. A Fund's distribution rate is computed by dividing the most
recent monthly distribution per share annualized, by the current net asset value
per share. A 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.
A 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 a Fund's last monthly
distribution. A 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 Funds' Prospectus).

         Other data that may be advertised or published about each 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:

         Net investment income will be determined in accordance with rules
established by the SEC. The price per share of Class A shares will include the
maximum sales charge imposed on purchases of Class A shares which decreases with
the amount of shares purchased, and the price per share of Class C shares will
include the sales charge imposed on purchases of Class C shares.

   
         For the thirty-day period ended December 31, 1998, the Bond Income
Strategy Fund's 30-day yield for Class A, Class B, Class C and Class Y was
4.63%, 4.15%, 4.11% and 5.30%respectively. For that same period, the 30-day
yield for the Class A, Class B, Class C and Class Y shares of the High Yield
Fund was 7.33%, 6.96%, 6.90% and 8.14% respectively.
    

         NON-STANDARDIZED PERFORMANCE. In addition, in order to more completely
represent a Fund's performance or more accurately compare such performance to
other measures of investment return, a 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 Funds may advertise their
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 MidCap 400 Index is designed to represent price
movements in the mid cap U.S. equity market. It contains companies chosen by the
Standard & Poors Index Committee for their size, liquidity and industry
representation. None of the companies in the S&P 400 overlap with those in the
S&P 500 Index or the S&P 600 Index. Decisions about stocks to be included and
deleted are made by the Committee which meets on a regular basis. S&P 400 

                                      -51-
<PAGE>   163
stocks are market cap weighted; each stock influences the Index in proportion to
its relative market cap. REITs are not eligible for inclusion.

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

         The Standard and Poor's Small Cap 600 index is designed to represent
price movements in the small cap U.S. equity market. It contains companies
chosen by the Standard & Poors Index Committee for their size, industry
characteristics, and liquidity. None of the companies in the S&P 600 overlap
with the S&P 500 or the S&P 400 (MidCap Index). The S&P 600 is weighted by
market capitalization. REITs are not eligible for inclusion.

         The NASDAQ Composite OTC Price Index is a market value-weighted and
unmanaged index showing the changes in the aggregate market value of
approximately 3,500 stocks.

         The Lehman Government Bond Index is a measure of the market value of
all public obligations of the U.S. Treasury; all publicly issued debt of all
agencies of the U.S. Government and all quasi-federal corporations; and all
corporate debt guaranteed by the U.S. Government. Mortgage backed securities,
bonds and foreign targeted issues are not included in the Lehman Government
Index.

         The Lehman Government/Corporate Bond Index is a measure of the market
value of approximately 5,300 bonds with a face value currently in excess of $1.3
trillion. To be included in the Lehman Government/Corporate Index, an issue must
have amounts outstanding in excess of $1 million, have at least one year to
maturity and be rated "Baa" or higher ("investment grade") by a nationally
recognized rating agency.

         The Russell 2000 Index represents the bottom two thirds of the largest
3000 publicly traded companies domiciled in the U.S. Russell uses total market
capitalization to sort its universe to determine the companies that are included
in the Index. Only common stocks are included in the Index. REITs are eligible
for inclusion.

         The Russell 2500 Index is a market value-weighted, unmanaged index
showing total return (i.e., principal changes with income) in the aggregate
market value of 2,500 stocks of publicly traded companies domiciled in the
United States. The Index includes stocks traded on the New York Stock Exchange
and the American Stock Exchange as well as in the over-the-counter market.

         The Morgan Stanley Capital International EAFE Index (the "EAFE Index")
is an unmanaged index, which includes over 1,000 companies representing the
stock markets of Europe, Australia, New Zealand and the Far East. The EAFE Index
is typically shown weighted by the market capitalization. However, EAFE is also
available weighted by Gross Domestic Product (GDP). These weights are modified
on July 1st of each year to reflect the prior year's 

                                      -52-
<PAGE>   164
GDP. Indices with dividends reinvested constitute an estimate of total return
arrived at by reinvesting one twelfth of the month end yield at every month end.
The series with net dividends reinvested take into account those dividends net
of withholding taxes retained at the source of payment.

         The Lehman Brothers High Yield BB Index is a measure of the market
value of public debt issues with a minimum par value of $100 million and rated
Ba1-Ba3 by Moody's. All bonds within the index are U.S. dollar denominated,
non-convertible and have at least one year remaining to maturity.

         In addition, from time to time in reports and promotions: (1) a 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 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.

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

                                      TAXES

         Each Fund is treated as a separate entity for accounting and tax
purposes. Each 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, each 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.

         Each 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

                                      -54-
<PAGE>   166
annual minimum distribution requirements. Each Fund intends under normal
circumstances to avoid liability for such tax by satisfying such distribution
requirements.

         If a 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"), that 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 applicable
Fund to recognize taxable income or gain without the concurrent receipt of cash.
Any Fund that is permitted to acquire stock in foreign 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 a 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 a Fund's investment in stock or
securities, possibly including speculative currency positions or currency
derivatives not used for hedging purposes 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.
    

   
         Some Funds 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. If qualified, a fund may elect to pass through such foreign taxes and any
associated tax deductions or credits to their shareholders, who therefore
generally will report such amounts on their own tax returns.
    

         For Federal income tax purposes, each 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 applicable Fund and would not be distributed as such to
shareholders.

         Each 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, each Fund

                                      -55-
<PAGE>   167
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, a 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 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 Funds may restrict a Fund's ability to enter into futures, options, and
forward transactions.

         Certain options, futures and forward foreign currency transactions
undertaken by a 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 a 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 a 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 a Fund's distributions
to shareholders. The Funds 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 a 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.

         A Fund may recognize gain with respect to appreciated stock, debt, and
partnership interests upon entering into short sales, offsetting notional
principal contracts, futures, forwards, and options with respect to the same or
substantially identical property.

         Distributions from a Fund's current or accumulated earnings and profits
("E&P"), as computed for federal income tax purposes, will be taxable as
described in the Funds' prospectus

                                      -56-
<PAGE>   168
whether taken in shares or in cash. Distributions, if any, in excess of E&P will
constitute a return of capital, which will first reduce an investor's tax basis
in a Fund's shares and thereafter (after such basis is reduced to zero) will
generally give rise to capital gains. Shareholders electing to receive
distributions in the form of additional shares will have a cost basis for
federal income tax purposes in each share so received equal to the amount of
cash they would have received had they elected to receive the distributions in
cash, divided by the number of shares received.

         At the time of an investor's purchase of shares of a Fund (other than
Money Market Fund), a portion of the purchase price is often attributable to
realized or unrealized appreciation in the Fund's portfolio or undistributed
taxable income of the Fund. Consequently, subsequent distributions from such
appreciation or income may be taxable to such investor even if the net asset
value of the investor's shares is, as a result of the distributions, reduced
below the investor's cost for such shares, and the distributions in reality
represent a return of a portion of the purchase price.

         Upon a redemption of shares of a Fund, other than Money Market Fund,
(including by exercise of the exchange privilege) a shareholder may realize a
taxable gain or loss depending upon his basis in his shares. Such gain or loss
will be treated as capital gain or loss if the shares are capital assets in the
shareholder's hands and, will be taxed depending upon the shareholder's tax
holding period for the shares. A sales charge paid in purchasing shares of a
Fund cannot be taken into account for purposes of determining gain or loss on
the redemption or exchange of such shares within 90 days after their purchase to
the extent shares of the Fund are subsequently acquired without payment of a
sales charge pursuant to the reinvestment or exchange privilege. Such
disregarded load will result in an increase in the shareholder's tax basis in
the shares subsequently acquired. Also, any loss realized on a redemption or
exchange will be disallowed to the extent the shares disposed of are replaced
with shares of the same Fund within a period of 61 days beginning 30 days before
and ending 30 days after the shares are disposed of, such as pursuant to an
election to reinvest dividends or capital gain distributions automatically. In
such a case, the basis of the shares acquired will be adjusted to reflect the
disallowed loss. Any loss realized upon the redemption of shares with a tax
holding period of six months or less will be treated as a long-term capital loss
to the extent of any amounts treated as distributions of long-term capital gain
with respect to such shares.

         For purposes of the dividends received deduction available to
corporations, dividends received by a Fund, if any, from U.S. domestic
corporations in respect of the stock of such corporations held by the Fund, for
federal income tax purposes, for at least 46 days during the 90-day period that
begins 45 days before the stock becomes ex-dividend and distributed and
designated by the Fund may be treated as qualifying dividends. The holding
period for dividends on preferred stock is 91 days during the 180-day period
that begins 90 days before the stock becomes ex-dividend. Corporate shareholders
must meet the minimum holding period requirement stated above (46 or 91 days)
with respect to their shares of the applicable Fund in order to qualify for the
deduction and, if they borrow to acquire such shares, may be denied a portion of
the dividends received deduction. The entire qualifying dividend, including the
otherwise deductible

                                      -57-
<PAGE>   169
amount, will be included in determining the excess (if any) of a corporate
shareholder's adjusted current earnings over its alternative minimum taxable
income, which may increase its alternative minimum tax liability. Additionally,
any corporate shareholder should consult its tax adviser regarding the
possibility that its basis in its shares may be reduced, for federal income tax
purposes, by reason of "extraordinary dividends" received with respect to the
shares, for the purpose of computing its gain or loss on redemption or other
disposition of the shares.

         Different tax treatment, including penalties on certain excess
contributions and deferrals, certain pre-retirement and post-retirement
distributions and certain prohibited transactions, is accorded to shareholder
accounts maintained as qualified retirement plans. Shareholders should consult
their tax advisers for more information.

         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
a 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 Funds in their
particular circumstances.

         Non-U.S. investors not engaged in a U.S. trade or business with which
their investment in a Fund is effectively connected will be subject to U.S.
Federal income tax treatment that is different from that described above. These
investors may be subject to non-resident alien withholding tax at the rate of
30% (or a lower rate under an applicable tax treaty) on amounts treated as
ordinary dividends from a Fund and, unless an effective IRS Form W-8 or
authorized substitute is on file, to 31% backup withholding on certain other
payments from the Fund. Non-U.S. investors should consult their tax advisers
regarding such treatment and the application of foreign taxes to an investment
in any Fund.

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

                                    APPENDIX

         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.
<PAGE>   172
         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 AND 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:
<PAGE>   173
         -        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.
<PAGE>   174
         -        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.

The Hartford Mutual Funds, Inc.
Hartford Plaza
Hartford, CT 06115

Gentlemen:

I have examined the Articles of Incorporation of The Hartford Mutual Funds, Inc.
(hereafter referred to as "Fund"); the By-Laws of the Fund; documents evidencing
various pertinent corporate proceedings; and such other things considered to be
material to determine the legality of the sale of the authorized but unissued
shares of the Fund's stock. Based upon my examination, it is my opinion that the
Fund is a validly organized and existing corporation of the State of Maryland
and it is legally authorized to issue its shares of common stock, at prices
determined as described in the Fund's currently effective Prospectus, when such
shares are properly registered under all applicable federal and state securities
laws.

Based upon the foregoing, it is my opinion that the Fund's shares were, when
issued for cash consideration as described in the Fund's currently effective
prospectus, validly issued, fully paid and nonassessable stock of the Fund.

I hereby consent to the inclusion of this Opinion as an Exhibit to the Fund's
Post-Effective Amendment to its Registration Statement.

Very truly yours,

/s/ Kevin J. Carr

Kevin J. Carr
Counsel
