AS AN INFORMED INVESTOR, YOU SHOULD KNOW....



All of the 18 Funds involve risk, and all of them offer the potential for
reward. This means you can lose money--and you can make money. At IDEX, we've
structured the Funds so that each offers a slightly different degree of risk and
reward than the others.

In this prospectus, we've arranged the Funds in order of risk/reward from
highest to lowest. Notice the scale at the right. It represents the full range
of risks and rewards, along with the types of securities associated with each
level. This scale appears near the explanation of each Fund, with an arrow
pointing to the risk/reward level of that Fund. 

What risk/reward level is for you? Here's how you can tell: 

HOW WELL DO YOU HANDLE FLUCTUATIONS IN SHARE PRICE (ACCOUNT VALUE)? The higher a
Fund is on the risk/reward scale, the more its price is likely to move up and
down from day to day. If this makes you uncomfortable, you might prefer an
investment at the lower end of the scale that doesn't fluctuate in price as
much. 

ARE YOU LOOKING FOR A HIGHER RATE OF RETURN? Generally, the higher the potential
return, the higher the risk. If you find the potential to make more money to be
worth the possibility of losing more, then a Fund at the higher end of the scale
may be right for you.

A final note: Except for money market funds, MUTUAL FUNDS ARE LONG-TERM
INVESTMENTS. For best results, you should be prepared to commit to this
investment for at least several years due to market cycles.

Each Fund has an investment objective that it tries to achieve through
investing. The objective can be changed without shareholder vote.


TO HELP YOU UNDERSTAND...

"icons", graphic road signs that let you know at a glance the subject of the

IDEX INTERNATIONAL EQUITY FUND


SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE OBJECTIVE OF THE INTERNATIONAL EQUITY FUND IS LONG-TERM GROWTH OF CAPITAL.
Its sub-advisers, Scottish Equitable Investment Management Limited (SEIM) and GE
Investment Management Incorporated (GEIM), seek to achieve this objective by
investing Fund assets in: 

/bullet/ common stocks and other equity securities of foreign ("non-U.S.") 
         companies traded on overseas exchanges and foreign over-the-counter
         markets 

/bullet/ preferred stocks, as well as convertible stocks and bonds of such
         companies 

/bullet/ warrants and rights, which are securities that entitle the Fund to
         buy more stock at a later date (rights expire, warrants do not) 

/bullet/ Depository receipts including American Depository Receipts ("ADRS"), 
         Global Depository Receipts ("GDRS") and European Depository Receipts 
         ("EDRS") 

This Fund aims to appeal to investors who seek long-term capital growth through
foreign investments, and who are able to tolerate the significant risks in such
investments.

[GRAPHIC OMITTED] STRATEGIES 

Each day, the cash that flows into the Fund for investment is divided equally by
SEIM and GEIM, and they manage each portion separately from then on.

Normally, 65% of the Fund's assets are invested in at least 50 stocks of
companies of 15 to 25 different countries. The Fund is never invested in
companies of fewer than 12 countries, other than the U.S.

The Fund invests broadly, not only in the larger stock markets of Europe and
Japan, but also, to a lesser extent in the smaller markets of Asia, Emerging
Europe and Latin America.

Overseas economies usually don't move in the same direction and operate
differently. This creates situations the Fund aims to take advantage of through
asset allocation among international markets.

SEIM looks for countries where economic growth conditions are favorable and
where stock market valuations don't reflect that potential. It then looks for
companies whose earnings potential is not reflected in the share price.

GEIM looks for companies expected to grow faster than their markets, and whose
stock prices don't fully reflect that. Attributes of such companies are strong
earnings growth, low price-to-book value, strong cash flow and presence in an
industry that is experiencing strong growth and has high quality management,
financial strength and sufficient liquidity. 

[GRAPHIC OMITTED] RISKS 

The Fund is subject to the following principal investment risks:

/bullet/ STOCKS

While stocks have historically outperformed other asset classes over the long
term, they tend to go up and down more dramatically over the shorter term. These
price movements may result from factors affecting individual companies,
industries or the securities market as a whole.

Because the stocks the Fund holds fluctuate in price, the value of your
investment in the Fund will go up and down.

/bullet/ FOREIGN SECURITIES 

Investments in foreign securities involve risks relating to political, social
and economic developments abroad as well as risks resulting from difference in
regulations to which U.S. and foreign issuers and markets are subject. These
risks include:

        /bullet/ Changes in currency values
        /bullet/ Currency speculation
        /bullet/ Currency trading costs
        /bullet/ Different accounting and reporting practices 
        /bullet/ Less information available to the public 
        /bullet/ Less (or different) regulation of securities' markets 
        /bullet/ More complex business negotiations 
        /bullet/ Less liquidity 
        /bullet/ More fluctuations in market prices
        /bullet/ Delays in settling foreign securities transactions 
        /bullet/ Higher costs for holding foreign securities (custodial fees)
        /bullet/ Vulnerability to seizure and taxes
        /bullet/ Political instability and small markets
        /bullet/ Different market trading days

/bullet/ CONVERTIBLE SECURITIES

As with all debt securities, the market value of convertible debt securities
tends to decline as interest rates increase and, conversely, to increase as the
interest rates decline.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund.

These and other risks are fully described in the section entitled "Full
Explanation of Strategies and Risks," beginning on page 28.

The two tables below show the Fund's annual returns and its long-term
performance. The first table shows you how the Fund's performance has varied
from year to year. Results are for Class A shares without deducting the sales
load. (If deducted, the results would be less.) The second compares the Fund's
performance over time to that of the Morgan Stanley Capital
International-Europe, Asia and Far East Index (MSCI-EAFE), a widely recognized
unmanaged index of market performance. Both tables assume reinvestment of
dividends and capital gain distributions. As with all mutual funds, past

IDEX GLOBAL FUND


SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE OBJECTIVE OF THE GLOBAL FUND IS LONG-TERM GROWTH OF CAPITAL IN A MANNER
CONSISTENT WITH PRESERVATION OF CAPITAL. The sub-adviser, Janus Capital
Corporation (Janus), seeks to achieve this objective by investing primarily in:

/bullet/ foreign stocks of foreign and domestic issuers

The Fund may invest on a worldwide basis in companies and other organizations of
any size, regardless of country of organization or place of principal business
activity.

The Fund may use forward foreign currency contracts for hedging. A forward
foreign currency contract is an agreement between contracting parties to
exchange an amount of currency at some future time at an agreed upon rate. These
contracts are used as a hedge against fluctuations in foreign exchange rates.

The Fund aims to appeal to investors who want capital growth without being
limited to investments in U.S. securities, and who can stand the risks
associated with foreign investing. 

[GRAPHIC OMITTED] STRATEGIES 

Janus' main strategy is to use a "bottom up" approach to build the Fund's
portfolio. They seek to identify individual companies with earnings growth
potential that may not be recognized by the market at large. 

Foreign securities are generally selected on a stock-by-stock basis without
regard to defined allocation among countries or geographic regions.

When evaluating foreign investments, Janus (in addition to looking at individual
companies) considers such factors as:

/bullet/ expected levels of inflation in various countries 
/bullet/ government policies that might affect business conditions 
/bullet/ the outlook for currency relationships 
/bullet/ prospects for economic growth among countries, regions or geographic 
         areas

[GRAPHIC OMITTED] RISKS

The Fund is subject to the following investment risks:

/bullet/ STOCKS

While stocks have historically outperformed other asset classes over the long
term, they tend to go up and down more dramatically over the shorter term. These
price movements may result from factors affecting individual companies,
industries or the securities market as a whole. 

Because the stocks the Fund holds fluctuate in price, the value of your
investment in the Fund will go up and down.

/bullet/ FOREIGN SECURITIES

Investments in foreign (non-U.S.) securities risks relating to political, social
and economic developments abroad, as well as risks resulting from the
differences between the regulations to which U.S. and foreign issuer markets are
subject.

        /bullet/ Changes in currency values 
        /bullet/ Currency speculation
        /bullet/ Currency trading costs 
        /bullet/ Different accounting and reporting practices
        /bullet/ Less information available to the public 
        /bullet/ Less (or different) regulation of securities markets 
        /bullet/ More complex business negotiations 
        /bullet/ Less liquidity 
        /bullet/ More fluctuations in prices 
        /bullet/ Delays in settling foreign securities transactions 
        /bullet/ Higher costs for holding shares (custodial fees) 
        /bullet/ Vulnerability to seizure and taxes 
        /bullet/ Political instability and small markets 
        /bullet/ Different market trading days 
        /bullet/ Forward foreign currency contracts for hedging

/bullet/ HEDGING

The hedging strategy may not be successful if the Fund manager is unable to
accurately predict movements in the prices of individual securities held by the
Fund, or if the strategy does not correlate well with the Fund's investments. A
loss may result when hedging currency exposure.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund.

These and other risks are fully described in the section entitled "Full
Explanation of Strategies and Risks," beginning on page 28.

SMALL CAP FRONTIER FUND


SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE INVESTMENT OBJECTIVE OF THE SMALL CAP FRONTIER FUND IS TO SEEK LONG-TERM
GROWTH OF CAPITAL BY INVESTING PRIMARILY IN COMMON STOCKS OF SMALL GROWTH
COMPANIES. The Fund's sub-adviser, T. Rowe Price Associates, Inc. ("T. Rowe
Price"), seeks to achieve this objective by investing Fund assets in:

/bullet/ Common stocks of small-cap growth companies
/bullet/ Futures

This Fund aims to appeal to investors who want an aggressive, long-term approach
to building capital and who can tolerate significant fluctuations inherent in
small-cap stock investing.

[GRAPHIC OMITTED] STRATEGIES

This Fund will invest at least 80% of total assets in common stocks of small-cap
growth companies. Small-cap growth companies are those companies that are still
in the process of developing and are expected by T. Rowe Price to achieve
long-term earnings growth rates that reach new highs over time. For the purposes
of this Fund, a small-cap growth company is defined as one whose market
capitalization is smaller than 90% of the companies in the S&P 500. As of
December 31, 1998, this included companies with market caps under approximately
$__billion, but the upper size limit will vary with market fluctuations. (A
company's market "cap" is found by multiplying its shares outstanding by its
stock price.)

The Fund will be more broadly diversified than the typical small-cap growth
fund; once the Fund achieves sufficient size, the top 25 holdings will not
compose a significant portion of total Fund assets.

Stock selection is based on a variety of quantitative models designed by T. Rowe
Price to identify the key characteristics of small-cap growth stocks. Based on
these models, stocks are selected in a "top down" manner so that the portfolio
as a whole reflects characteristics T. Rowe Price considers important, such as
valuations (price/earnings or price/book value ratios, for example) and
projected earnings growth.

The Fund will typically hold minimum cash reserves to maximize exposure to this
market area. To help the Fund manage cash flow efficiently and maintain
consistent market exposure, the Fund may also buy and sell stock index futures.

The Fund may take a temporary defensive position when the securities trading
markets or the economy are experiencing excessive volatility or a prolonged
general decline, or other adverse conditions exist. Under these circumstances,
the Fund may be unable to achieve its investment objective.

[GRAPHIC OMITTED] RISKS

The Fund is subject to the following principal investment risks:

/bullet/ STOCKS

         While stocks have historically outperformed other asset classes over
         the long term, they tend to go up and down more dramatically over the
         shorter term. These price movements may result from factors affecting
         individual companies, industries or the securities market as a whole.
         
         Because the stocks the Fund holds fluctuate in price, the value of your
         investment in the Fund will go up and down.

/bullet/ SMALL-CAP COMPANIES

         Investing in small companies involves greater risk than is customarily
         associated with more established companies. Stocks of small companies
         may be subject to more abrupt or erratic price movements than larger
         company securities. Small companies often have limited product lines,
         markets, or financial resources, and their management may lack depth
         and experience.

         Also, growth stocks can experience steep price declines if the
         company's earnings disappoint investors. Since the Fund will typically
         be fully invested in this market sector, investors are fully exposed to
         its volatility.

/bullet/ QUANTITATIVE MODELS

         Stocks selected using quantitative models may not be effective and may
         cause overall returns to be lower than if other methods are used.

/bullet/ FUTURES

         Futures involve additional investment risks and transaction costs, and
         draw upon skills and experience which are different than those needed
         to pick other securities. Special risks include:

         /bullet/ Inaccurate market predictions
         /bullet/ Imperfect correlation
         /bullet/ Illiqudity
         /bullet/ Tax considerations

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund.

Explanation of Strategies and Risks," beginning on page __.

MID-CAP SUMMIT FUND


SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE INVESTMENT OBJECTIVE OF THE MID-CAP SUMMIT FUND IS TO SEEK CAPITAL
APPRECIATION. The Fund's sub-adviser, Pilgrim Baxter & Associates, Ltd.
("Pilgrim") seeks to achieve this objective by investing Fund assets in: 

/bullet/ common stocks of medium capitalization companies 
/bullet/ convertible securities 

This Fund aims to appeal to investors who want long-term growth of capital and
who can tolerate fluctuations inherent in stock investing.

[GRAPHIC OMITTED] STRATEGIES

In seeking capital appreciation, Pilgrim normally invests at least 65% of the
Fund's total assets in common stocks and convertible securities issued by
companies with market capitalizations between $500 million and $10 billion. The
Fund invests primarily in companies that Pilgrim believes have outlooks for
significant earnings growth and capital-appreciation potential. The Fund may
also invest in foreign (non-U.S.) securities, warrants and rights.

Pilgrim may take a temporary defensive position when the securities trading
markets or the economy are experiencing excessive volatility or a prolonged
general decline, or other adverse conditions exist. Under these circumstances,
the Fund may be unable to achieve its investment objective.

[GRAPHIC OMITTED] RISKS

The Fund is subject to the following principal investment risks:

/bullet/ STOCKS

         While stocks have historically outperformed other asset classes over
         the long term, they tend to go up and down more dramatically over the
         shorter term. These price movements may result from factors affecting
         individual companies, industries or the securities market as a whole.
         
         Because the stocks the Funds may hold fluctuate in prices, the value
         of your investment in the Fund will go up and down.

/bullet/ MEDIUM SIZED COMPANIES

         These companies present additional risks because their earnings are
         less predictable, their share price more volatile, and their securities
         less liquid than larger, more established companies.

/bullet/ CONVERTIBLE SECURITIES

         As with all debt securities, the market value of convertible debt
         securities tends to decline as interest rates increase and, conversely,
         to increase as interest rates decline.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund.

IDEX CAPITAL APPRECIATION FUND


SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE OBJECTIVE OF THE CAPITAL APPRECIATION FUND IS LONG-TERM GROWTH OF CAPITAL.
Its sub-adviser, Janus Capital Corporation (Janus), seeks to achieve this
objective by:

/bullet/ investing at least 50% of the Fund's assets in the stocks of
         medium-sized companies

Medium-sized companies are those whose market capitalizations, at the time of
purchase, fall within the range of the S&P Mid Cap 400 Index. As of December 31,
1998, this range was $______million to $_____billion.

Subject to this policy, the Fund may also invest in the stocks of smaller or
larger companies as well.

This Fund is classifies as "non-diversiifed." As it's used in this prospectus,
the term "non-diversified" means a fund focuses its investments in a particular
type of investment, industry or country. This fund may invest as much as 50% of
its assets in the securities of as few as two issuers.

This Fund aims to appeal to investors who want capital growth and who can stand
the risks associated with common stock investments.

[GRAPHIC OMITTED] STRATEGIES

This Fund invests in industries and stocks of companies that Janus believes are
experiencing favorable demand for their products and services, and are operating
in favorable competitive and regulatory environments.

Janus use a "bottom up" approach by seeking to identify individual companies
with earnings growth potential that may not be recognized by the market.
Although themes may emerge in the Fund, stocks are usually selected without
regard to any defined industry sector or other similarly defined selection
procedure. Though income is not an objective of the Fund, some holdings might
produce incidental income.


[GRAPHIC OMITTED] RISKS

The Fund is subjet to the following investment risks:

/bullet/ STOCKS


While stocks have historically outperformed other asset classes over the long
term, they tend to go up and down more dramatically over the shorter term. These
price movements may result from factors affecting individual companies,
industries or the securities market as a whole.

Because the stocks the Fund holds fluctuate in price, the value of your
investment in the Fund will go up and down.

/bullet/ MEDIUM-SIZED COMPANIES

These companies present additional risks because their earnings are less
predictable, their share price more volatile, and their securities less liquied
than larger, more established companies.

/bullet/ NON-DIVERSIFIED

This Funds non-diversification characteristic makes it more susceptible to any
single economic, political or regulatory occurrence. The share price will
flucutate more than a comparable diversified fund.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund.

These and other risks are fully described in the section entitled "Full
Explanation of Strategies and Risks," beginning on page 28.

IDEX C.A.S.E. FUND

SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE OBJECTIVE OF THE C.A.S.E. FUND IS ANNUAL GROWTH OF CAPITAL THROUGH
INVESTMENT IN COMPANIES WHOSE MANAGEMENT, FINANCIAL RESOURCES AND FUNDAMENTALS
APPEAR ATTRACTIVE ON A SCALE MEASURED AGAINST EACH COMPANY'S PRESENT VALUE. Its
sub-adviser, C.A.S.E. Management, Inc. (C.A.S.E.), intends to achieve this
objective by investing Fund assets in:

     /bullet/ common stocks
     /bullet/ preferred stocks
     /bullet/ convertible stocks

The Fund's assets are invested in companies whose stocks are traded on national
exchanges or over-the-counter markets. C.A.S.E. focuses on companies that are
fundamentally strong compared to other companies in the same industry, the same
sector and the broad market.

C.A.S.E. believes that above-average performance is as much a matter of
eliminating bad situations as it is discovering good ones.

This Fund aims to appeal to investors who seek growth in excess of the S&P 500
in good and bad markets, but want a diversified portfolio of companies with
below-market risk characteristics. Investors should be comfortable with the
price fluctuations of such a stock portfolio. 

[GRAPHIC OMITTED] STRATEGIES

Using proprietary forms of research, C.A.S.E. selects companies after evaluating
the current economic cycle, and identifying attractive sectors, industries and
company-specific circumstances.

The Fund invests in common, preferred and convertible stocks of firms that
C.A.S.E. believes show below-market risk, supported by below-market multiples,
along with above-average fundamentals. These fundamentals include return on
equity, price-to-earnings ratio and other balance sheet factors that contribute
to long-term capital growth. 

C.A.S.E. applies its proprietary forms of research to companies that exhibit
superior products and above-average growth rates along with sound management and
financials.

Each company selected for the Fund is monitored against more than two dozen
disciplines, including: 

/bullet/ insiders' activity 
/bullet/ market style leadership 
/bullet/ earnings surprise 
/bullet/ analysts' change in earnings projections 
/bullet/ return on equity
/bullet/ 5-year earnings-per-share growth rate 
/bullet/ price-earnings ratio 
/bullet/ price-to-book ratio 
/bullet/ price-to-cash flow 
/bullet/ institutional activity and holdings 
/bullet/ relative strength price change 
/bullet/ price-to-200-day moving average 
/bullet/ price-to-historical rising inflation 
/bullet/ price-to-declining U.S. dollar 
/bullet/ earnings projected change 
/bullet/ quarterly earnings per-share growth rate 

Stocks are sold when C.A.S.E. views them as overvalued, or when C.A.S.E. feels
the stocks have lost their strong fundamentals.

[GRAPHIC OMITTED] RISKS 

The Fund is subject to the following investment risks: 

/bullet/ STOCKS

While stocks have historically outperformed other asset classes over the long
term, they tend to go up and down more dramatically over the shorter term. These
price movements may result from factors affecting individual companies,
industries, or the securities market as a whole. 

Because the stocks the Fund holds fluctuate in price, the value of your
investment in the Fund will go up and down.

/bullet/ PROPRIETARY RESEARCH 

C.A.S.E.'s proprietary forms of research may not be effective and may cause
overall returns to be lower than if other forms of research are used.

/bullet/ CONVERTIBLE SECURITIES

As with all debt securities, the market value of convertible debt securities
tends to decline as interest rates increase and, conversely, to increase as the
interest rates decline.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund.

These and other risks are fully described in the section entitled "Full
Explanation of Strategies and Risks," beginning on page 28.

IDEX VALUE EQUITY FUND


SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE OBJECTIVE OF THE VALUE EQUITY FUND IS MAXIMUM CONSISTENT TOTAL RETURN WITH
MINIMUM RISK TO PRINCIPAL. Its sub-adviser, NWQ Investment Management Company,
Inc. (NWQ), employs a value-oriented approach to investing. 

The Fund seeks to achieve this objective by investing primarily in:

     /bullet/ common stocks
     /bullet/ money market and short-term instruments (Treasury Bills)
     /bullet/ Amercian Depositary Receipts and exchange listed foreign stocks

This Fund aims to appeal to investors who seek both capital preservation and
long-term capital appreciation.

[GRAPHIC OMITTED] STRATEGIES

NWQ will use statistical measures to look for above-average stock valuations,
screening for below-average price-to-earnings and price-to-book ratios,
above-average dividend yields and strong financial stability. 

NWQ also identifies those market sectors believed to benefit from long-term
positive fundamentals, and focuses on the companies within these sectors which
represent above-average statistical value and are undervalued when purchased.

The Fund consists of ________ mid-capitalization to large-capitalization
companies. NWQ differs from many other value-oriented managers in that it:

/bullet/ uses earnings averaged over both strong and weak periods in evaluating 
         cyclical companies 
/bullet/ focuses on quality of earnings 
/bullet/ invests in relative value 
/bullet/ concentrates in industries and sectors that have strong long-term 
         fundamentals

[GRAPHIC OMITTED] RISKS

The Fund is subject to the following principal investment risks:

/bullet/ STOCKS

While stocks have historically outperformed other asset classes over the long
term, they tend to go up and down more dramatically over the shorter term. These
price movements may result from factors affecting individual companies,
industries, or the securities market as a whole.

Because the stocks the Fund holds fluctuate in price, the value of your
investment in the Fund will go up and down.

/bullet/ MEDIUM-SIZED COMPANIES

These companies present additional risks because their earnings are less
predictable, their share price more volatile, and their securities less liquid
than larger more established companies.

/bullet/ FOREIGN SECURITIES

Investments in foreign securities involve risks relating to political, social
and economic developments abroad as well as risks resulting from difference in
regulations to which U.S. and foreign issuers and markets are subject.
These risks include:

/bullet/  Changes in currency values
/bullet/  Currency speculation
/bullet/  Currency trading costs
/bullet/  Different accounting and reporting practices
/bullet/  Less information available to the public
/bullet/  Less (or different) regulation of securities' markets
/bullet/  More complex business negotiations
/bullet/  Less liquidity
/bullet/  More fluctuations in market prices
/bullet/  Delays in settling foreign securities transactions
/bullet/  Higher costs for holding foreign securities (custodial fees)
/bullet/  Vulnerability to seizure and taxes
/bullet/  Political instability and small markets
/bullet/  Different market trading days

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund. 

These and other risks are fully described in the section entitled "Full
Explanation of Strategies and Risks," beginning on page 28.

MID-CAP OPPORTUNITIES FUND

SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE INVESTMENT OBJECTIVE OF THE MID-CAP OPPORTUNITIES FUND IS TO SEEK CAPITAL
APPRECIATION. The Fund's sub-adviser, Salomon Brothers Asset Management Inc.
("SBAM"), seeks to achieve this objective by investing Fund assets in:

/bullet/ common stocks
/bullet/ convertible securities
/bullet/ cash and cash equivalents

This Fund aims to appeal to investors who want long-term growth of capital and
who can tolerate fluctuations in their investments.

[GRAPHIC OMITTED] STRATEGIES

This Fund is classified as "non-diversified." As it is used in this prospectus,
the term "non-diversified" means a fund focuses its investments in a particular
type of investment, industry or country. The Fund will primarily invest in
common stocks, or securities convertible into or exchangeable for common stocks,
such as convertible preferred stocks or convertible debentures.

In seeking capital appreciation, the Fund may purchase securities of: seasoned
issuers; small companies; newer companies; and new issues. The Fund may be
subject to wide fluctuations in market value. Portfolio securities may have
limited marketability or may be widely and publicly traded.

SBAM anticipates that the Fund's investments generally will be in securities of
companies which it considers to reflect the following characteristics:

/solid box/ Undervalued share prices

/solid box/ Special situations such as existing or possible changes in
            management or management policies, corporate structure or control,
            capitalization, regulatory environment, or other circumstances
            which could be expected to favor earnings or market price of such
            company's shares

/solid box/ Growth potential due to technological advances, new methods in
            marketing or production, new or unique products or services, changes
            in demands for products or services or other significant new
            developments

SBAM uses a bottom-up, fundamental research process to select the Fund's
securities. They seek to identify individual companies with earnings growth
potential that may not be recognized by the market.

SBAM may take a temporary defensive position when the securities trading markets
or the economy are experiencing excessive volatility or a prolonged general
decline, or other adverse conditions exist. Under these circumstances, the Fund
may be unable to pursue its investment objective.

[GRAPHIC OMITTED] RISKS

The Fund is subject to the following principal investment risks:

/bullet/ STOCKS

         While stocks have historically outperformed other asset classes over
         the long term, they tend to go up and down more dramatically over the
         shorter term. These price movements may result from factors affecting
         individual companies, industries or the securities market as a whole.

         Because the Fund's holdings may fluctuate in price, the value of your
         investment in the Fund will go up and down.

/bullet/ CONVERTIBLE SECURITIES

         The market value of convertible debt securities tends to decline as
         interest rates increase and, conversely, to increase as interest rates
         decline.

/bullet/ NON-DIVERSIFIED

         This Fund's non-diversification makes it more susceptible to any
         single, economic, political or regulatory occurrence. The share price
         will fluctuate more than a comparable diversified fund.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund.

These and other risks are fully described in the section entitled "Full
Explanation of Strategies and Risks," beginning on page __.

IDEX AGGRESSIVE GROWTH FUND


SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE OBJECTIVE OF THE AGGRESSIVE GROWTH FUND IS LONG-TERM CAPITAL APPRECIATION.
The Fund's sub-adviser, Fred Alger Management, Inc. (Alger), seeks to achieve
this objective by investing Fund assets in: 

/bullet/ equity securities such as common or perferred stocks

/bullet/ convertible securities (convertible securities are securities which can
         be exchanged for or converted into common stock of such companies)

/bullet/ U.S. dollar denominated securities of foreign issuers (American 
         Depository Receipts)

/bullet/ money market instruments, including repurchase agreements 

/bullet/ repurchase agreements

This Fund aims to appeal to investors who seek capital growth aggressively, and
who can tolerate wide swings in the value of their investment.

[GRAPHIC OMITTED] STRATEGIES 

Except during defensive periods (as when the markets are down), the Fund invests
at least 85% of its assets in common stocks, which may include stocks of
developing companies, of older companies that are entering a new stage of
growth, and of companies whose products or services have a high unit volume
growth rate.

The Fund may also use leveraging, a technique that involves borrowing money to
invest in an effort to enhance shareholder returns.

The Fund's manager may take a temporary defensive position when the securities
trading markets or the economy are experiencing excessive volatility or a
prolonged general decline, or other adverse conditions exist. During this time,
the Fund may invest up to 100% of its assets in money market instruments and
cash equivalents. Under these circumstances, the Fund may be unable to pursue
its investment objective.

[GRAPHIC OMITTED] RISKS

The Fund is subject to the following principal investment risks:

/bullet/ STOCKS

While stocks have historically outperformed other asset classes over the long
term, they tend to go up and down more dramatically over the shorter term. These
price movements may result from factors affecting individual companies,
industries or the securities market as a whole. 

Because the stocks the Fund holds fluctuate in price, the value of your
investment in the Fund will go up and down.

/bullet/ INVESTING AGGRESSIVELY

        /bullet/ Value of developing-company stocks may drop significantly
        /bullet/ Rights, options and futures contracts may not be exercised and 
                 may expire worthless
        /bullet/ Warrants and rights may be less liquid than stocks 
        /bullet/ Leveraging practices may make the Fund more volatile.

/bullet/ CONVERTIBLE SECURITIES

As with all debt securities, the market value of convertible debt securities
tends to decline as interest rates increase and, conversely, to increase as
the interest rates decline.

/bullet/ REPURCHASE AGREEMENTS

Repurchase agreements involve the risk that the seller will fail to repurchase
the security, as agreed.  In that case, the Fund will bear the risk of market
value fluctuations until the security can be sold and may encounter delays and
incur costs in liquidating the securitiy.  In the event of bankruptcy or
insolvency of the seller, delays and costs are incurred.

/bullet/ ADRs

Investments in foreign securities involve risks relating to political, social
and economic developments abroad as well as risks resulting from differences
in regulations to which U.S. and foreign issuers and markets are subject.  These
risks include:

        /bullet/ Changes in currency values
        /bullet/ Currency specuation
        /bullet/ Currency trading costs
        /bullet/ More fluctuations in market prices
        /bullet/ Less information available

The value of these securities may change daily based on changes in interest
rates, and other market conditions and factors.

        /bullet/ Changes in interest rates
        /bullet/ Length of time to maturity
        /bullet/ Issuers defaulting on their obligations to pay  interest or  
                 return principal

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund. 

These and other risks are fully described in the section entitled "Full
Explanation of Strategies and Risks," beginning on page 28.

IDEX GROWTH FUND

SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE OBJECTIVE OF THE GROWTH FUND IS GROWTH OF CAPITAL. Its sub-adviser, Janus
Capital Corporation (Janus), seeks to achieve this objective by investing mainly
in:

/bullet/ common stocks listed on national exchanges or on NASDAQ which Janus
         believes have a good potential for capital growth

This Fund aims to appeal to investors who want capital growth in a broadly
diversified stock portfolio, and who can tolerate significant fluctuations in
the value of their investment.

[GRAPHIC OMITTED] STRATEGIES

The Fund's main strategy is to invest almost all of its assets in common stocks
at times when Janus believes the market environment favors such investing.

Janus generally takes a "bottom up" approach to building the stock portfolio. In
other words, Janus seeks to identify individual companies with earnings growth
potential that may not be recognized by the stock market at large.

Although themes may emerge in the Fund, securities are generally selected
without regard to any defined industry sector or other similarly defined
selection procedure. Realization of income is not a significant investment
consideration for the Fund and any income realized on the Fund's investments is
incidental to its objective.

[GRAPHIC OMITTED] RISKS

The Fund is subject to the following investment risks:

/bullet/ STOCKS

While stocks have historically outperformed other asset classes over the long
term, they tend to go up and down more dramatically over the shorter term. These
price movements may result from factors affecting individual companies,
industries or the securities market as a whole. 

Because the stocks the Fund holds fluctuate in price, the value of your
investment in the Fund will go up and down.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund.

These and other risks are fully described in the section entitled "Full
Explanation of Strategies and Risks," beginning on page 28.

BLUE CHIP FUND

SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE INVESTMENT OBJECTIVE OF THE BLUE CHIP FUND IS TO SEEK LONG-TERM GROWTH OF
CAPITAL. The Fund's sub-adviser, Goldman Sachs Asset Management ("GSAM"), seeks
to achieve this objective by investing primarily in: 

/bullet/    equity securities

This Fund aims to appeal to investors who seek long- term growth of capital and
who can tolerate fluctuations inherent in stock investing.

[GRAPHIC OMITTED] STRATEGIES

This Fund will invest at least 90% of total assets in a diversified portfolio of
equity securities that are considered by GSAM to have long term capital
appreciation potential. Although the Fund will invest primarily in publicly
traded U.S. securities, it may invest up to 10% of its total assets in foreign
(non-U.S.) securities, including securities of issuers in emerging (developing)
countries and securities quoted in foreign currencies.

Equity securities for this Fund are selected based on their prospects for above
average growth. GSAM will select securities of growth companies trading, in
GSAM's opinion, at a reasonable price relative to other industries, competitors
and historical price/earnings multiples.

In order to determine whether a security has favorable growth prospects, GSAM
ordinarily looks for one or more of the following characteristics in relation to
the security's prevailing price: prospects for above average sales and earnings
growth per share; high return on invested capital; free cash flow generation;
sound balance sheet, financial and accounting policies, and overall financial
strength; strong competitive advantages; effective research, product
development, and marketing; pricing flexibility; strength of management; and
general operating characteristics that will enable the company to compete
successfully in its marketplace.

The Fund generally will invest in companies whose earnings are believed to be in
a relatively strong growth trend, or, to a lesser extent, in companies in which
significant further growth is not anticipated but whose market value per share
is thought to be undervalued.

The Fund's manager may take a temporary defensive position when the securities
trading markets or the economy are experiencing excessive volatility or a
prolonged general decline, or other adverse conditions exist. Under these
circumstances, the Fund may be unable to achieve its investment objective.

[GRAPHIC OMITTED] RISKS

The Fund is subject to the following principal investment risks:

/bullet/ STOCKS

         While stocks have historically outperformed other asset classes over
         the long term, they tend to go up and down more dramatically over the
         shorter term. These price movements may result from factors affecting
         individual companies, industries or the securities market as a whole.

         Because the stocks the Fund holds fluctuate in price, the value of your
         investment will go up and down.

/bullet/ FOREIGN SECURITIES

Investments in foreign securities involve risks relating to political, social
and economic developments abroad as well as risks resulting from difference in
regulations to which U.S. and foreign issuers and markets are subject.
These risks include:

/bullet/  Changes in currency values
/bullet/  Currency speculation
/bullet/  Currency trading costs
/bullet/  Different accounting and reporting practices
/bullet/  Less information available to the public
/bullet/  Less (or different) regulation of securities' markets
/bullet/  More complex business negotiations
/bullet/  Less liquidity
/bullet/  More fluctuations in market prices
/bullet/  Delays in settling foreign securities transactions
/bullet/  Higher costs for holding foreign securities (custodial fees)
/bullet/  Vulnerability to seizure and taxes
/bullet/  Political instability and small markets
/bullet/  Different market trading days

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund.

These and other risks are fully described in the section entitled "Full
Explanation of Strategies and Risks," beginning on page __.

DIVIDEND GROWTH FUND

SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

The investment objective of the Dividend Growth Fund is to provide an increasing
level of dividend income, long-term capital appreciation, and reasonable current
income through investments primarily in dividend-paying stocks. The fund's
sub-adviser, T. Rowe Price Associates, Inc. ("T. Rowe Price"), seeks to achieve
this objective by investing Fund assets in:

/bullet/ Dividend-paying common stocks with favorable prospects for increasing
         dividends and long-term appreciation

/bullet/ Foreign securities

/bullet/ Futures and options

This Fund aims to appeal to investors who want increasing income over time along
with capital appreciation and who can tolerate significant fluctuations in the
value of their investment.

[GRAPHIC OMITTED] STRATEGIES

This Fund typically invests at least 65% of total assets in common stocks of
dividend-paying companies that T. Rowe Price expects these companies to increase
their dividends over time and also provide long-term appreciation.

T. Rowe Price looks for stocks with sustainable, above-average growth in
earnings and dividends, and attempts to buy them when they are temporarily out
of favor or undervalued by the market. In selecting investments, T. Rowe Price
favors companies with one or more of the following:

/bullet/ Either a track record of, or the potential for, above-average earnings 
         and dividend growth

/bullet/ A competitive current dividend yield

/bullet/ A sound balance sheet and solid cash flow to support future dividend
         increases

/bullet/ A sustainable competitive advantage and leading market position

/bullet/ Attractive valuations such as a relatively high dividend yield

Most of the Fund's assets will be invested in U.S. common stocks. However, T.
Rowe Price may also purchase other types of securities such as foreign
securities, convertibles, warrants, preferred stocks, and corporate and
government debt when considered consistent with the Fund's objective. Futures
and options may be used for any number of reasons, including: managing the
Fund's exposure to securities prices and foreign currencies; to enhance income;
to manage cash flows efficiently; or to protect the value of portfolio
securities.

[GRAPHIC OMITTED] RISKS

The Fund is subject to the following principal investment risks:

/bullet/ STOCKS

         While stocks have historically outperformed other asset classes over
         the long term, they tend to go up and down more dramatically over the
         shorter term. These price movements may result from factors affecting
         individual companies, industries or the securities market as a whole.

         Because the stocks the Fund may hold fluctuates in price, the value of
         your investment in the Fund will go up and down.

/bullet/ FOREIGN SECURITIES

         Investments in foreign securities involve risks relating to political,
         social and economic developments abroad as well as risks resulting from
         differences in regulations to which U.S. and foreign issuers and
         markets are subject. These risks include:

         /bullet/ Changes in currency values
         /bullet/ Currency speculation
         /bullet/ Currency trading costs
         /bullet/ Different accounting and reporting practices
         /bullet/ Less information available to the public
         /bullet/ Less (or different), regulation of securities markets
         /bullet/ More complex business negotiations
         /bullet/ Less liquidity
         /bullet/ More fluctuations in market prices
         /bullet/ Delays in settling foreign securities transactions
         /bullet/ Higher costs for holding foreign securities (custodial fees)
         /bullet/ Vulnerability to seizure and taxes
         /bullet/ Political instability and small markets
         /bullet/ Different market trading days

/bullet/ FUTURES AND OPTIONS

         Futures and options involve additional investment risks and transaction
         costs, and draw upon skills and experience which are different than
         those needed to pick other securities. Special risks include:

         /bullet/ Inaccurate market predictions
         /bullet/ Imperfect correlation
         /bullet/ Illiquidity
         /bullet/ Tax considerations

IDEX TACTICAL ASSET ALLOCATION FUND


SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE OBJECTIVE OF THE TACTICAL ASSET ALLOCATION FUND IS PRESERVATION OF CAPITAL
AND COMPETITIVE INVESTMENT RETURNS. The Fund's sub-adviser, Dean Investment
Associates (Dean), seeks to achieve this objective by investing Fund assets in:

/bullet/ income-producing common and preferred stocks 
/bullet/ debt obligations of U.S. issuers, some of which will be convertible 
         into common stocks 
/bullet/ U.S. Treasury bonds, notes and bills 
/bullet/ money market funds 

In selecting stocks, Dean focuses on high-quality, liquid, large capitalization
stocks, using a "bottom-up" screening process to identify stocks that are
statistically undervalued. Dean's ultimate goal is to choose stocks whose price
has been driven down by a market that has "over-reacted" to its perceived risks.
With this approach, the Fund seeks to achieve a dividend income yield higher
than that of the Russell 1000 Index.

This Fund aims to appeal to investors who want a combination of capital growth
and income, and who can tolerate the risks associated with an actively-traded
portfolio which shifts assets between equity and debt.

[GRAPHIC OMITTED] STRATEGIES 

This Fund employs an investment technique called "asset allocation," which
shifts assets from one class of investment to another (such as from equity to
debt) when Dean anticipates changes in market direction.

The Fund will seek to enhance returns in rising stock markets by increasing its
allocation to equity, then protect itself in falling stock markets by reducing
equity exposure and shifting into fixed-income investments, as well as into
money market funds (up to 10% of total assets).

Dean has developed forecasting models to predict movements in the stock market
for both short (12 to 18-month) and long (3 to 5-year) time periods. These
models help compare the risks and rewards Dean anticipates in holding stocks
versus debt instruments and money market funds.

Thus, the models determine when Dean is to "tactically" adjust the Fund's asset
allocation among stocks, bonds, U.S. debt obligations and money market funds.

[GRAPHIC OMITTED] RISKS 

The Fund is subject to the following principal investment risks: 

/bullet/ STOCKS

While stocks have historically outperformed other asset classes over
the long term, they tend to go up and down more dramatically over the shorter
term. These price movements may result from factors affecting individual
companies, industries, or the securities market as a whole. 

Because the stocks the Fund holds fluctuate in price, the value of your
investment in the Fund will go up and down.

/bullet/ CONVERTIBLE SECURITIES 

As with all debt securities, the market value of convertible debt securities
tends to decline as interest rates increase and, conversely, to increase as the
interest rates decline.

/bullet/ FIXED-INCOME SECURITIES 

The value of these securities may change daily based on changes in the interest
rates, and other market conditions and factors. The risks include:

        /bullet/ Changes in interest rates
        /bullet/ Length of time to maturity
        /bullet/ Issuers defaulting on their obligations to pay interest or 
                 return principal

/bullet/ STATISTICAL MODELS

Securities selected using statistical models may result in incorrect asset
allocations causing overall returns to be lower than if other methods of
selection were used.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund.

These and other risks are fully described in the section entitled "Full
Explanation of Strategies and Risks," beginning on page 28.

IDEX STRATEGIC TOTAL RETURN FUND


SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE OBJECTIVE OF THE STRATEGIC TOTAL RETURN FUND IS CURRENT INCOME, LONG-TERM
GROWTH OF INCOME, AND CAPITAL APPRECIATION. Its sub-adviser, Luther King Capital
Management Corporation (Luther King), seeks to achieve this objective by
investing Fund assets in a blend of equity and fixed-income securities which
include:

         /bullet/ common stocks
         /bullet/ corporate bonds
         /bullet/ convertible preferred stocks
         /bullet/ corporate convertible bonds
         /bullet/ U.S. Treasury notes

The Fund seeks to achieve an income yield greater than the average yield of the
stocks in the S&P 500.

The Fund invests mainly in the stocks and bonds of companies with established
operating histories and strong fundamental characteristics. The majority of the
stocks the Fund buys will be listed on a national exchange or traded on NASDAQ
or domestic over-the-counter markets. 

This Fund aims to appeal to investors who seek capital appreciation and income
growth through a strategic blend of stocks and bonds, and who desire a
fundamentally-oriented investment approach, emphasizing risk management.

[GRAPHIC OMITTED] STRATEGIES

The Fund seeks to invest in a blend of equity and fixed-income securities to
achieve a balance of capital appreciation and investment income while limiting
volatility. The Fund will also invest in convertible securities, which have both
equity and fixed-income characteristics. In choosing such securities, Luther
King looks for companies with strong fundamental characteristics. It considers
factors such as:

/bullet/ balance sheet quality 
/bullet/ cash flow generation 
/bullet/ earnings and dividend growth record and outlook 
/bullet/ profitability levels 

In some cases, Luther King bases its selections on other factors. For example,
some securities may be bought at an apparent discount to their appropriate
value, with the anticipation that they'll increase in value over time. 

Luther King closely analyzes a company's financial status and a security's
valuation in an effort to control risk at the individual security level. In
addition, the growth elements of the Fund's equity investments drive capital
appreciation.

As part of its income-oriented strategy, Luther King expects to invest about 25%
of the Fund's assets in fixed-income securities, some of which will be
convertible into common stocks, and no more than 20% of its assets in stocks
that don't pay a dividend. Up to 10% of the Fund's assets may be invested in
high yield/high-risk bonds (commonly known as "junk bonds"). These bonds are
rated below investment grade by the primary rating agencies. 

[GRAPHIC OMITTED] RISKS 

The Fund is subject to the following principal investment risks:

/bullet/ STOCKS

While stocks have historically outperformed other asset classes over the long
term, they tend to go up and down more dramatically over the shorter term. These
price movements may result from factors affecting individual companies,
industries or the securities market as a whole.

Because the stocks the Fund holds fluctuate in price, the value of your
investment in the Fund will go up and down.

/bullet/ FIXED-INCOME SECURITIES 

The value of these securities may change daily based on changes in the interest
rates, and other market conditions and factors. The risks include:

        /bullet/ Changes in interest rates
        /bullet/ Length of time to maturity
        /bullet/ Issuers defaulting on their obligations to 
                 pay interest or return principal

/bullet/ HIGH-YIELD/HIGH-RISK SECURITIES

        /bullet/ Credit risk
        /bullet/ Greater sensitivity to interest rate movements 
        /bullet/ More speculative 
        /bullet/ Greater vulnerability to economic changes 
        /bullet/ Decline in market value in event of default 
        /bullet/ Less liquidity

/bullet/ CONVERTIBLE SECURITIES

As with all debt securities, the market value of convertible debt securities
tends to decline as interest rates increase and, conversely, to increase as
interest rates decline.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund.

These and other risks are fully described in the section entitled "Full
Explanation of Strategies and Risks," beginning on page 28.

IDEX BALANCED FUND


SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE OBJECTIVE OF THE BALANCED FUND IS LONG-TERM CAPITAL GROWTH, CONSISTENT WITH
PRESERVATION OF CAPITAL AND BALANCED BY CURRENT INCOME. The Fund's sub-adviser,
Janus Capital Corporation (Janus), seeks to achieve this objective by normally
investing in: 

       /bullet/ equity securities
       /bullet/ convertible securities
       /bullet/ fixed-income securities
       /bullet/ high-yield/high-risk securities (commonly known as "junk bonds")

This Fund aims to appeal to investors who seek capital growth and income from
the same investment, but who also want an investment that sustains value by
maintaining a balance between equity and debt (stocks and bonds). The Fund is
not for investors who desire a consistent level of income. 

[GRAPHIC OMITTED] STRATEGIES 

     The basic strategy of the Fund is to maintain a growth component and an
income component. Normally, 40% to 60% of the Fund's securities are chosen for
their GROWTH potential, and the remaining 40% to 60% are chosen for their INCOME
potential.

The growth component is expected to consist mainly of common stocks in companies
and industries that Janus believes are experiencing favorable demand for their
products and services, and that are operating in a favorable competitive and
regulatory climate. In its analysis, Janus looks for companies with earnings
growth potential that may not be recognized by the market. 

The income component will consist of securities that Janus believes have income
potential. Such securities may include equity securities, convertible securities
and all types of debt securities. 

At least 25% of the Fund's assets will normally be invested in fixed-income
securities, including bonds and preferred stock. 

The sub-adviser uses a "bottom up" approach by seeking to identify individual
companies with earning potential that may not be recognized by the market at
large. Securities are selected without regard to any industry sector or other
similarly defined selection procedure. 

Up to 35% of the Fund's assets may be invested in high/yield/high-risk bonds
(commonly known as "junk bonds"). These bonds are rated below investment grade
by the primary rating agencies. 

The Fund may shift assets between the growth and income portions of its
portfolio, based on Janus' analysis of the market and conditions in the economy.
If Janus believes that at a particular time growth investments will provide
better returns than the yields from income-producing investments, the Fund may
put a greater emphasis on growth. The reverse may also take place. 

[GRAPHIC OMITTED] RISKS 

The Fund is subject to the following principal investment risks: 

/bullet/ STOCKS

While stocks have historically outperformed other asset classes over the long
term, they tend to go up and down more dramatically over the shorter term. These
price movements may result from factors affecting individual companies,
industries, or the securities market as a whole. 

Because the stocks the Fund holds fluctuate in price, the value of your
investment in the Fund will go up and down.

/bullet/ CONVERTIBLE SECURITIES 

As with all debt securities, the market value of a convertible debt security
tends to decline as interest rates increase and, conversely, to increase as the
interest rates decline.

/bullet/ FIXED-INCOME SECURITIES 

The value of these securities may change daily based on changes in the interest
rates, and other market conditions and factors. The risks include:

        /bullet/ Changes in interest rates
        /bullet/ Length of time to maturity
        /bullet/ Issuers defaulting on their obligations to pay interest or 
                 return principal

/bullet/ HIGH-YIELD/HIGH-RISK SECURITIES

        /bullet/ Credit risk 
        /bullet/ Greater sensitivity to interest rate movements 
        /bullet/ More speculative
        /bullet/ Greater vulnerability to economic changes 
        /bullet/ Decline in market value in event of default 
        /bullet/ Less liquidity

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund.

These and other risks are fully described in the section entitled "Full
Explanation of Strategies and Risks," beginning on page 28.

IDEX FLEXIBLE INCOME FUND


SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE OBJECTIVE OF THE FLEXIBLE INCOME FUND IS MAXIMUM TOTAL RETURN FOR
SHAREHOLDERS, CONSISTENT WITH PRESERVATION OF CAPITAL, BY ACTIVELY MANAGING A
PORTFOLIO OF INCOME-PRODUCING SECURITIES.

The Fund normally invests at least 80% of its total assets in income-producing
securities of both foreign and domestic companies. The Fund's sub-adviser, Janus
Capital Corporation ("Janus"), seeks to achieve this objective by investing
primarily in:

/bullet/ corporate debt securities
/bullet/ lower-rated securities, including bonds considered less than investment
         grade (high-yield/high risk bonds) of both foreign and domestic issuers
/bullet/ mortgage- and other asset-backed securities
/bullet/ convertible securities
/bullet/ preferred stock
/bullet/ income-producing common stock

This Fund aims to appeal to investors who want current income enhanced by the
potential for capital growth, and who are willing to tolerate fluctuation in
principal value caused by changes in interest rates as well as the risks
associated with substantial investments in high-yield/high-risk bonds (commonly
known as "junk bonds") or unrated bonds of domestic or foreign issuers.

[GRAPHIC OMITTED] STRATEGIES 

The Fund seeks maximum current income by investing mainly in corporate bonds
that offer higher yields, but more risk than higher rated bonds. While the Fund
may buy bonds of any maturity, the Fund's average maturity may vary
substantially, depending upon Janus' analysis of market, economic and financial
conditions at the time.

To increase the potential of higher returns, the Fund has no pre-established
standards for the quality of the debt instruments it buys.

The Fund may also buy unrated debt securities of both domestic and foreign
issuers, and may at times have substantial holdings of such high-yield/high-risk
bonds.

In determining the creditworthiness of bond issuers, Janus uses, but doesn't
rely solely on, credit ratings.

Janus seeks to diversify the Fund's investments across many securities and
sectors. Currency risk is generally avoided through hedging and other means.

[GRAPHIC OMITTED] RISKS 

The Fund is subject to the following principal investment risks: 

/bullet/ FIXED-INCOME SECURITIES

The value of these securites may change daily based on changes in the interest
rates, and other market conditions and factors. Risks include:

        /bullet/ Changes in interest rates
        /bullet/ Length of time to maturity
        /bullet/ Issuers defaulting on their obligations to pay interest or 
                 return principal

/bullet/ HIGH-YIELD/HIGH-RISK SECURITIES

        /bullet/ Credit risk
        /bullet/ Greater sensitivity to interest rate movements 
        /bullet/ More speculative 
        /bullet/ Greater vulnerability to economic changes 
        /bullet/ Decline in market value in event of default 
        /bullet/ Less liquidity

/bullet/ STOCKS

While stocks have historically outperformed other asset classes over the long
term, they tend to go up and down more dramatically over the shorter term. These
price movements may result from factors affecting individual companies,
industries, or the securities market as a whole. 

Because the stocks the Fund holds fluctuate in price, the value of your
investment in the Fund will go up and down.

/bullet/ CONVERTIBLE SECURITIES

As with all debt securities, the market value of a convertible debt security
tends to decline as interest rates increase and, conversely, to increase as the
interest rates decline. 

/bullet/ FOREIGN SECURITIES

Investments in foreign securities involve risks relating to political, social
and economic developments abroad as well as risks resulting from difference in
regulations to which U.S. and foreign issuers and markets are subject. These
risks include:

        /bullet/ Changes in currency values
        /bullet/ Currency speculation
        /bullet/ Currency trading costs
        /bullet/ Different accounting and reporting practices
        /bullet/ Less information available to the public
        /bullet/ Less (or different) regulation of securities' markets
        /bullet/ More complex business negotiations
        /bullet/ Less liquidity
        /bullet/ More fluctuations in market prices
        /bullet/ Delays in settling foreign securities transactions
        /bullet/ Higher costs for holding foreign securities (custodial fees)
        /bullet/ Vulnerability to seizure and taxes
        /bullet/ Political instability and small markets
        /bullet/ Different market trading days

/bullet/ MORTGAGE- AND OTHER ASSET-BACKED SECURITIES

        /bullet/ Repayment sooner than stated maturity dates resulting in 
                 greater price and yield volatility than with traditional 
                 fixed-income securities
        /bullet/ Prepayments resulting in lower return
        /bullet/ Values may change based on creditworthiness of issuers
        /bullet/ Interest rate risks

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund.

These and other risks are fully described in the section entitled "Full
Explanation of Strategies and Risks," beginning on page 28.

IDEX INCOME PLUS FUND

SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE OBJECTIVE OF THE INCOME PLUS FUND IS TO SEEK AS HIGH A LEVEL OF CURRENT
INCOME AS IS CONSISTENT WITH THE AVOIDANCE OF EXCESSIVE RISK. Its sub-adviser,
AEGON USA Investment Management, Inc. (AIMI), seeks to achieve this objective by
investing Fund assets in a diversified portfolio of: 

/bullet/ fixed-income securities including investment grade bonds and 
         high-yield/high-risk bonds (commonly known as "junk bonds"). 

This Fund aims to appeal to investors who seek high current income and are
willing to tolerate the fluctuation in principal value associated with changes
in interest rates.

Consistent with this policy, when investing in rated securities, the Fund buys
those rated B or better by Moody's or S&P. When investing in rated commercial
paper, the Fund buys those rated Prime-2 or better by Moody's or A-2 or better
by S&P. The Fund may invest in unrated securities which, in AIMI's judgment, are
of equivalent quality. If the rated securities held by the Fund are downgraded,
AIMI will consider whether to keep these securities.

The Fund may not invest in rated corporate securities that are rated below
investment grade, if such holdings are more than 50% of its total holdings of
securities (other than commercial paper).

[GRAPHIC OMITTED] STRATEGIES 

AIMI's strategy is to achieve yields as high as possible while managing
risk. AIMI uses a "top down/bottom up" approach in managing the Fund's assets.
The "top down' approach is to adjust the risk profile of the Fund. They analyze
four factors that affect the movement of fixed-income bond prices which include:
economic indicators; technical indicators that are specific to the high-yield
market; investor sentiment and valuation. Analysis of these factors assists AIMI
in its decisions regarding the Fund's portfolio allocations.

AIMI has developed a proprietary credit model that is the foundation of its
"bottom up" analysis. The model tracks historical cash flow numbers and
calculates credit financial ratios. Because high-yield companies are of higher
financial risk, AIMI does a thorough credit analysis of all companies in the
Fund's portfolio, as well as all potential acquisitions.

Each potential buy and sell candidate is analyzed by AIMI from both the "top
down" and "bottom up" strategies. An industry may look attractive in one area,
but not the other. They can then review the results of their analysis and decide
whether or not to proceed with a transaction.

For temporary defensive purposes, the Fund may invest some or all of its assets
in short-term obligations.

[GRAPHIC OMITTED] RISKS

The Fund is subject to the following principal investment risks:

/bullet/ FIXED-INCOME SECURITIES

The Value of these securities may change daily based on changes in the interest
rates, and other market conditions and factors. Risks include:

        /bullet/ Changes in interest rates
        /bullet/ Length of time to maturity
        /bullet/ Issuers defaulting on their obligations to pay interest or 
                 return principal

/bullet/ HIGH-YIELD/HIGH-RISK SECURITIES

        /bullet/ Credit risk
        /bullet/ Greater sensitivity to interest rate movements 
        /bullet/ More speculative 
        /bullet/ Greater vulnerability to economic changes 
        /bullet/ Decline in market value in event of default 
        /bullet/ Less liquidity

/bullet/ PROPRIETARY RESEARCH

AIMI's proprietary forms of research may not be effective and may cause overall
returns to be lower than if other forms of research are used.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund.

IDEX TAX-EXEMPT FUND


SUMMARY OF RISKS AND RETURNS

[GRAPHIC OMITTED] OBJECTIVE AND POLICIES

THE OBJECTIVE OF THE TAX-EXEMPT FUND IS MAXIMUM CURRENT INTEREST INCOME EXEMPT
FROM FEDERAL INCOME TAX, CONSISTENT WITH PRESERVATION OF CAPITAL. Its
sub-adviser, AEGON USA Investment Management, Inc. (AIMI), seeks to achieve this
objective by ordinarily investing at least 75% of its net assets in: 

/bullet/ municipal obligations rated in the four highest grades of Moody's 
         or S&P 
/bullet/ municipal commercial paper rated the highest by Moody's or S&P 
/bullet/ unrated municipal notes (6-month to 3-year maturity) of issuers with at
         least one issue of bonds outstanding that are rated in Moody's or S&P's
         four highest grades.

Also, the Fund may buy unrated municipal obligations that AIMI considers equal
in quality to the four highest ratings of Moody's or S&P. Unrated municipal
securities may be less liquid than rated securities, and therefore may be
riskier than rated municipal securities.

Bonds in the fourth category are speculative. The Fund's policies doe not limit
how much of the portfolio may be bonds in these categories, as long as AIMI
believes the objective of preserving capital is being met.

These obligations are issued by states, territories or possessions of the U.S.,
the District of Columbia and their political subdivisions, agencies, etc., and
the Fund will invest in them only if the interest they pay is based on the
opinion of bond counsel, exempt from federal income tax.

The maturity of securities in the Fund is expected to be between 20 and 35
years.

This Fund aims to appeal to investors who seek high current federal tax-free
income and are willing to tolerate the fluctuation in principal value associated
with changes in interest rates. Yields on municipal obligations are typically
lower than on similar taxable securities. Such investors will generally have
higher taxable incomes.

The Fund is not for tax-exempt retirement programs, since they would receive no
benefit from the tax-exempt nature of most of the Fund's income.

[GRAPHIC OMITTED] STRATEGIES

AIMI takes an approach it believes to be conservative, trying to participate in
the market's advances while preserving capital on the downside, in order to
provide solid risk-adjusted returns for the shareholders of the Fund. The Fund
is managed by assessing key factors for the tax-exempt environment. The duration
and maturity structure of the Fund's portfolio generally reflects the interest
rate outlook of AIMI's Fixed Income Strategy Committee. 

Yields on municipal obligations depend upon:

/bullet/ Type or classification of the issuer
/bullet/ Maturity
/bullet/ Size and structure of the deal
/bullet/ Creditworthiness

Continuous changes in these areas are monitored by AIMI, who decides when the
awards are appropriate for the degree of risk taken. The Fund's portfolio is
broadly diversifed among all municipal obligations.

AIMI may take a temporary defensive position by investing up to 20% of its
assets in lower-yielding and taxable instruments when the securities trading
markets or the economy are experiencing excessive volatility or a prolonged
general decline, or other adverse conditions exist. Under these circumstances,
the Fund may be unable to achieve its investment objective.

[GRAPHIC OMITTED] RISKS

The Fund is subject to the following investment risks:

/bullet/ MUNICIPAL OBLIGATIONS 

        /bullet/ Their yields are usually lower than on similar, but taxable 
                 securities
        /bullet/ The income may be subject to state and local taxes 
        /bullet/ The income may be a preference item for determining the federal
                 alternative minimum tax
        /bullet/ Unrated municipal securities may be less liquid than rated 
                 securities
        /bullet/ Congress occasionally considers restricting or eliminating the 
                 federal tax exemption
        /bullet/ Obligations could ultimately be federally taxable

/bullet/ FIXED-INCOME SECURITIES

The value of these securities may change daily based on changes in the interest
rates, and other market conditions and factors. These risks include:

        /bullet/ Fluctuations in market value 
        /bullet/ Changes in interest rates 
        /bullet/ Length of time to maturity 
        /bullet/ Issuers defaulting on their obligations to pay interest or 
                 return principal

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed
by, any bank, and are not federally insured by the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency of the U.S.
government. You may lose money if you invest in this Fund. 

These and other risks are fully described in the section entitled "Full
Explanation of Strategies and Risks," beginning on page 28.

FULL EXPLANATION OF STRATEGIES
AND RISKS

HOW TO USE THIS SECTION

In the discussions of the individual Funds on pages 2 through __, you found
descriptions of the strategies and risks associated with each. In those pages,
you were referred to this section for a more complete description of the risks.
For best understanding, first read the description of the Fund you're interested
in. Then refer to this section and read about the risks particular to that Fund.
For even more discussions of strategies and risks, see the Statement of
Additional Information, which is available upon request. See the back cover of
this prospectus for information on how to order the SAI.

[GRAPHIC OMITTED]

THE FUNDS ARE DIVERSIFIED. All the Funds (except the Capital Appreciation Fund
and Mid-Cap Opportunities Fund) place their assets in a number of different
investments and investment classes. Sometimes this involves investing in other
countries; often it means choosing investments that produce lower returns, but
are expected to decline less in value during adverse markets. Diversification
reduces risk by making it less likely that a poor performance by one investment
will materially affect the Fund's portfolio as a whole. This is one of the
reasons mutual funds are such popular and widely-held investments.

[GRAPHIC OMITTED]

INVESTING IN COMMON STOCKS. Many factors cause common stocks to go up and down
in price. A major one is the financial performance of the company. Other factors
include the overall economy, conditions in a particular industry, and monetary
factors like interest rates. When your Fund holds stocks, there's a risk that
some or all of them may be down in price when you choose to sell, causing you to
lose money. This is called MARKET RISK.

[GRAPHIC OMITTED]

INVESTING IN PREFERRED STOCKS. Because these stocks come with a promise to pay a
stated dividend, their price depends more on the size of the dividend than on
the company's performance. But if a company fails to pay the dividend, its
preferred stock is likely to drop in price. Changes in interest rates can also
affect their price. (See "Investing in Bonds", below.)

[GRAPHIC OMITTED]

INVESTING IN "CONVERTIBLES", PREFERRED STOCKS, AND BONDS. Since preferred stocks
and corporate bonds pay a stated return, their prices usually don't depend on
the price of the company's common stock. But some companies issue preferred
stocks and bonds that are CONVERTIBLE into their common stocks. Linked to the
common stock in this way, convertible securities go up and down in price as the
common stock does, adding to their market risk.

[GRAPHIC OMITTED]

VOLATILITY. The more an investment goes up and down in price, the more VOLATILE
it's said to be. Volatility increases the market risk because even though your
Fund may go UP more than the market in good times, it may also go DOWN more than
the market in bad times. If you decide to sell when a volatile Fund is down, you
could lose more.

[GRAPHIC OMITTED]

INVESTING IN BONDS. Like common stocks, bonds fluctuate in value, though the
factors causing this are different, including:

/bullet/ CHANGES IN INTEREST RATES. Bond prices tend to move the
         opposite of interest rates. Why? Because when interest rates on new
         bond issues go up, rates on existing bonds stay the same and they
         become less desirable. When rates go down, the reverse happens. This is
         also true for most preferred stocks and some convertibles.

/bullet/ LENGTH OF TIME TO MATURITY. When a bond matures, the issuer
         must pay the owner its face value. If the maturity date is a long way
         off, many things can affect its value, so a bond is more volatile the
         farther it is from maturity. As that date approaches, fluctuations
         usually become smaller and the price gets closer to face value.

/bullet/ DEFAULTS. All bond issuers make at least two promises: (1) to
         pay interest during the bond's term and (2) to return principal when it
         matures. If an issuer fails to keep one or both of these promises, the
         bond will probably drop in price dramatically, and may even become
         worthless.

/bullet/ DECLINES IN RATINGS. At the time of issue, most bonds are rated
         by professional rating services, such as Moody's Investors Service,
         Inc. (Moody's) and Standard & Poor's Corporation (S&P). The stronger
         the financial backing behind the bond, the higher the rating. If this
         backing is weakened or lost, the rating service may downgrade the
         bond's rating. This is virtually certain to cause the bond to drop in
         price.

38 IDEX MUTUAL FUNDS / PROSPECTUS 1999
<PAGE>

/bullet/ LOW RATING. High-yield/high-risk securities (commonly known as
         "junk bonds") have greater credit risk, are more sensitive to interest
         rate movements, are considered more speculative, have a greater
         vulnerability to economic changes and are less liquid.

/bullet/ LACK OF RATING. Some bonds are considered speculative, or for
         other reasons are not rated. Such bonds must pay a higher interest rate
         in order to attract investors. They're considered riskier because of
         the higher possibility of default or loss of liquidity.

/bullet/ LOSS OF LIQUIDITY. If a bond is downgraded, or for other
         reasons drops in price, the market demand for it may "dry up." In that
         case, the bond may be hard to sell or "liquidate" (convert to cash).

[GRAPHIC OMITTED]

INVESTING IN FOREIGN (NON-U.S.) SECURITIES. These are investments offered by
foreign companies, governments and government agencies. They involve risks not
usually associated with U.S. securities, including:

/bullet/ CHANGES IN CURRENCY VALUES. Foreign securities are sold in
         currencies other than U.S. dollars. If a currency's value drops, the
         value of your Fund shares could drop too, even if the securities are
         strong. Dividend and interest payments may be lower. Factors affecting
         exchange rates are: differing interest rates among countries; balances
         of trade; amount of a country's overseas investments; and any currency
         manipulation by banks.

/bullet/ CURRENCY SPECULATION. The foreign currency market is largely
         unregulated and subject to speculation.

/bullet/ CURRENCY TRADING COSTS. Some Funds also invest in American
         Depository Receipts (ADRs) and American Depository Shares (ADSs). They
         represent securities of foreign companies traded on U.S. exchanges, and
         their values are expressed in U.S. dollars. Changes in the value of the
         underlying foreign currency will change the value of the ADR or ADS.
         The Fund incurs costs when it converts other currencies into dollars,
         and vice-versa.

/bullet/ EURO CONVERSION. On January 1. 1999, certain participating countries in
         the European Economic Monetary Union will adopt the "Euro" as their
         official currency. Other EU member countries may convert to the Euro at
         a later date. As of January 1, 1999, governments in participating
         countries will issue new debt and redenominate existing debt in Euros;
         corporations may choose to issue stocks or bonds in Euros or national
         currency. The new European Central Bank (the "ECB") will assume
         responsibility for a uniform monetary policy in participating
         countries. Euro conversion risks that could affect the Funds' foreign
         investments include: (1) the rediness of Euro payment, clearing, and
         other operational systems; (2) the legal treatment of debt instruments
         and financial contracts in existing national currencies rather than the
         Euro; (3) exchange-rate fluctuations between the Euro and non-Euro
         currencies during the transition period of January 1, 1999 through
         December 31, 2001 and beyond; (4) potential U.S. tax issues with
         respect to Fund securities; and (5) the ECB's abilities to manage
         monetary policies among the participating countries.

/bullet/ DIFFERING ACCOUNTING AND REPORTING PRACTICES. Foreign tax laws
         are different, as are laws, practices and standards for accounting,
         auditing and reporting data to investors.

/bullet/ LESS INFORMATION AVAILABLE TO THE PUBLIC. Foreign companies usually
         make far less information available to the public.

/bullet/ LESS REGULATION. Securities regulations in many foreign
         countries are more lax than in the U.S.

/bullet/ MORE COMPLEX NEGOTIATIONS. Because of differing business and
         legal procedures, the Fund might find it hard to enforce obligations or
         negotiate favorable brokerage commission rates.

/bullet/ LESS LIQUIDITY/MORE VOLATILITY. Some foreign securities are
         harder to convert to cash than U.S. securities,and their prices may
         fluctuate more dramatically.

/bullet/ SETTLEMENT DELAYS. "Settlement" is the process of completing a
         securities transaction. In many countries, this process takes longer
         than it does in the U.S.

/bullet/ HIGHER CUSTODIAL CHARGES. Fees charged by the Fund's custodian for
         holding shares are higher for foreign securities than that of domestic
         securities.

/bullet/ VULNERABILITY TO SEIZURE AND TAXES. Some governments can seize
         assets. They may also limit movement of assets from the country. Fund
         interest, dividends and capital gains may be subject to foreign
         withholding taxes.

/bullet/ POLITICAL INSTABILITY AND SMALL MARKETS. Developing countries
         can be politically unstable. Economies can be dominated by a few
         industries, and markets may trade a small number of securities.
         Regulation of banks and capital markets can be weak.

/bullet/ DIFFERENT MARKET TRADING DAYS. Foreign markets not be open for trading
         as U.S. markets are, and asset values can change before your
         transaction occurs.

/bullet/ HEDGING. A Fund may enter into forward currency contracts to
         hedge against declines in the value of securities denominated in, or
         whose value is tied to, a currency other than the U.S. dollar or to
         reduce the impact of currency fluctuation on purchases, and sales of
         such securities.

[GRAPHIC OMITTED]

INVESTING IN FUTURES, OPTIONS AND DERIVATIVES. Besides conventional securities,
your Fund may seek to increase returns by investing in financial contracts
related to its primary investments. Such contracts involve additional risks and
costs. Risks include:

/bullet/ INACCURATE MARKET PREDICTIONS. If the sub-adviser is wrong in
         its expectation, for example, with respect to interest rates,
         securities prices or currency markets, the contracts could produce
         losses instead of gains.

<PAGE>

/bullet/ PRICES MAY NOT MATCH. Movements in the price of the financial contracts
         may be used to offset movements in the price of other securities you
         own. If those prices don't correlate or match closely, the benefits of
         the transaction might be diminished.

/bullet/ ILLIQUID MARKETS. If there's no market for the contracts, the Fund may
         not be able to control losses.

/bullet/ TAX CONSEQUENCES. Sometimes the possibility of incurring high taxes on
         a transaction may delay closing out a position and limit the gains it
         would have produced.

[GRAPHIC OMITTED]

INVESTING IN TAX-EXEMPT SECURITIES. Some municipal obligations pay interest
that, while tax-exempt, may be considered a "preference item" for determining
the federal alternative minimum tax. This may result in your paying more tax
than you would have otherwise. Also, Congress periodically threatens to limit or
do away with the tax exemption or municipal obligations. If that happened, it
would substantially reduce the value of your Fund's assets.

[GRAPHIC OMITTED]

INVESTING IN SPECIAL 
SITUATIONS. Each Fund may invest in "special situations" from time to time.
Special situations arise when, in the opinion of a Fund manager, a company's
securities may be recognized, then increase considerably in price, due to: 

/bullet/ A NEW PRODUCT OR PROCESS

/bullet/ A MANAGEMENT CHANGE

/bullet/ A TECHNOLOGICAL BREAKTHROUGH

/bullet/ AN EXTRAORDINARY CORPORATE EVENT

/bullet/ A TEMPORARY IMBALANCE IN THE SUPPLY OF, AND DEMAND FOR, THE SECURITIES
         OF AN ISSUER

Investing in a special situation carries an additional risk of loss if the
expected development does not happen or does not attract the expected attention.
The impact of special situation investing to a Fund will depend on the size of
the Fund's investment in a situation.

42 IDEX MUTUAL FUNDS / PROSPECTUS 1999
<PAGE>

SHAREHOLDER INFORMATION

[GRAPHIC OMITTED] OPENING AN ACCOUNT

If you are opening an account through an IDEX representative, he or she can
assist you with all phases of your investment.

If you are investing through an authorized dealer, the dealer is responsible for
opening your account and providing your taxpayer ID number. If you already have
an IDEX account, you do not need additional documentation.

CHOOSING A SHARE CLASS 

The Fund offers three share classes, each with its own sales charge and expense
structure. (An additional class, Class T, is offered through the Growth
Portfolio but Class T shares are not available to new investors.)

If you are investing a large amount and plan to hold your shares for a long
period, Class A shares may make the most sense for you. If you are investing a
lesser amount, you may want to consider Class B shares (if you plan to invest
for a period of at least 5 years) or Class C shares (if you plan to invest for a
period less than 5 years).

Because all of your future investments in your account will be in the same share
class you designate when opening an account, you should make this decision
carefully. Your financial professional can help you choose the share class that
makes the best sense for you.


CLASS A SHARES - FRONT LOAD

With Class A shares, you pay a sales charge only when you buy shares.

If you are investing $1 million or more (either as a lump sum or through any of
the methods described above), you can purchase Class A shares without any sales
charge. However, if you redeem any of those shares within the first 24 months
after buying them, you will pay a 1% redemption charge, unless they were
purchased through a qualified retirement plan.

CLASS B SHARES - BACK LOAD

Class B shares are sold in amounts up to $500,000. With Class B shares, you
pay no sales charge when you invest, but you are charged a "contingent deferred
sales charge" (CDSC) when you sell shares you have held for six years or less,
as described in the table __________.

Class B shares automatically convert to Class A shares after 8 years, lowering
annual expenses from that time on.

CLASS C SHARES 

With class C shares, you pay an up-front sales charge of 1.00% based on offering
price. There are distribution and service fees of 0.90% per year. If you redeem
within 18 months from the date of purchase, you may incur a CDSC of 1.00%.

CONTINGENT DEFERRED SALES CHARGE

Class B and Class C shares are subject to a CDSC.

- --------------------------------------------------------------------------------
CLASS A SHARES -
FRONT LOAD
- --------------------------------------------------------------------------------
/bullet/ Initial sales charge of 5.5% or less; see table regarding Class A Share
         Quantity Discounts Table.

/bullet/ Discounts of sales charge for larger investments

/bullet/ 12b-1 distribution and service fee of 0.35%

/bullet/ Lower annual expenses than Class B or C shares due to lower
         distribution and service fees of 3.5%

- --------------------------------------------------------------------------------
CLASS B SHARES -
BACK LOAD
- --------------------------------------------------------------------------------
/bullet/ No up-front sales charge

/bullet/ Deferred sales charge of 5% or less on shares you sell within 6 years
         (see deferred sales charge table)

/bullet/ 12b-1 distribution and service fees of 1.00%

/bullet/ Automatic conversion to Class A shares after 8 years, reducing
         future annual expenses

- --------------------------------------------------------------------------------
CLASS C SHARES 
LEVEL LOAD
- --------------------------------------------------------------------------------
/bullet/ Initial sales charge of 1%

/bullet/ 12b-1 distribution and service fees of 0.90% per year (except for the 
         Tax-Exempt Fund which the distribution and service fee is 0.60%)

/bullet/ Deferred sales charge of 1% if you sell within 18 months of
         purchase.

/bullet/ No conversion to Class A shares after 8 years, so annual expenses do
         not decrease

- --------------------------------------------------------------------------------
CLASS T SHARES 
(CLOSED TO NEW INVESTORS)
- --------------------------------------------------------------------------------
/bullet/ Initial sales charge of 8.5% or less

/bullet/ Not subject to 12b-1 distribution and service fees

/bullet/ Sales charge percentage can be reduced in the sale four ways as Class A
         shares (see Class A Share Quantity Discounts Table)

- --------------------------------------------------------------------------------

Dividends and capital gains are not subject to the sales charge. There is no
charge on any increase in the value of your shares. To ensure that you pay the
lowest CDSC possible, IDEX will always use the shares with the lowest CDSC to
fill your redemption requests. If your shares are worth less than when you
bought them, the charge will be assessed on their current, lower value. In some
cases, the sales charge may be waived. See the SAI for complete information
about waivers.

CLASS T SHARES (GROWTH FUND ONLY)

(CLOSED TO NEW INVESTORS)

When you buy Class T shares of the Growth Portfolio, you pay an up-front sales
charge. You can reduce the sales charge percentage in the same four ways that
are described under Class A shares. Class T shares are not subject to annual
distribution and service fees.

You pay no sales charge when you redeem Class T shares. As with Class A shares,
if you pay no up-front sales charge because you are purchasing $1 million or
more of Class T shares. You will pay a deferred sales charge of 1% if you redeem
any of those shares within the first 24 months after buying them, unless they
were purchased through a qualified retirement plan. The charge is assessed on an
amount equal to the lesser of the then current market value of the original cost
of the shares being redeemed. No sales charge is imposed on net asset value
above the initial purchase.

Waivers of the sale charges are granted under certain conditions. Please see the
SAI for a description of these waivers. Persons eligible to buy Class T shares
at NAV may not impose a sales charge when they re-sell those shares.

NEW ACCOUNT APPLICATION

Fill out the New Account Application form which is included in this prospectus.
IRAs and other retirement accounts require a different application, which you
can request by calling or writing IDEX. You can avoid future inconvenience by
signing up for any services you think you may later use.

Note: On your application, be sure to include your social security number or
taxpayer identification number. If you don't, your account may be subject to
backup withholding, or be closed.

There are four ways that you can pay for your shares (shown below). The minimum
initial purchase is $500 for Class A, B and T Shares, and $1000 for Class C
shares. Later purchases are at least $50. Purchases through regular investment
plans, like the Automatic Investment Plan, have no minimum to open an account,
but you must invest at least $50 monthly per account.

<PAGE>
HOW TO EXCHANGE SHARES

You can exchange $50 or more of one Fund for shares in the same class of another
Fund. You may also exchange your shares into any one of the Money Market Funds
without a sales charge. Any CDSC will be calculated from the date you bought
your original shares. This means your new shares will be the same age as your
old shares, so your sales charge will not increase because of the exchange.

Prior to making exchange into a Fund that you do not own, read the prospectus
carefully. You can exchange shares over the telephone unless you have declined
the privilege on your application. You can also exchange shares of the same
class automatically at regular intervals, from one Fund to another. The
Systematic Exchange is set up similarly to that of a SWP.

MONEY MARKET EXCHANGE PRIVILEGE

You can exchange Class A and T shares for any of the Money Market Funds. You may
exchange Class B and C shares only into the Cash Equivalent Fund ("CEF") Money
Market Portfolio.

SPECIAL RULES FOR CLASS B OR C SHARES 
IN MONEY MARKET FUND EXCHANGES

When exchanging Class B or C shares for shares of the CEF Money Market Fund, you
will not be charged a CDSC. If you later sell the Class B or C shares of the
CEF, you will be charged the sales charge, but the time that you held those
Class B or C shares of the CEF will not count toward calculating the sales
charge.

There is no fee for exchanges; however, if three or more exchanges occur in a
calendar quarter, a $10 service fee per exchange will be assessed to your
account, on the account from which shares are being exchanged, for each exchange
after three.

SPECIAL SITUATIONS FOR EXCHANGING SHARES

/bullet/ Class T shares may be exchanged for only Class A shares of any
         IDEX Fund, other than the IDEX Growth Fund. Class A shares of all IDEX
         Funds are subject to 12b-1 distribution and service fees.

/bullet/ You may not exchange other classes of shares of the IDEX Funds for 
         Class T shares.

/bullet/ The Fund reserves the right to modify or terminate the exchange
         privilege at any time.

[GRAPHIC OMITTED]

OTHER ACCOUNT INFORMATION

MINIMUM INITIAL PURCHASE

/bullet/ $500 for Class A, B and T shares; $1,000 for Class C shares; additional
         purchases are a minimum of $50.

/bullet/ No minimum initial purchase for accounts that use the Automatic
         Investment Plan, but there is a $50 minimum purchase per account each
         month.

/bullet/ $1000, through authorized dealers.

IF YOUR CHECK, DRAFT OR ELECTRONIC TRANSFER IS RETURNED UNPAID BY YOUR BANK, THE
FUND MAY CHARGE A $15 FEE.

PRICING OF SHARES

The Fund calculates its net asset value per share (NAV) each day as of the close
of business on the New York Stock Exchange (currently 4:00 p.m. eastern time).
The share price of each class is calculated by dividing its net assets less
liability by the number of its shares outstanding.

If IDEX receives your order by that time you'll pay that day's NAV. If later, it
will be priced at the next day's NAV. Share prices may change when a Fund holds
shares in companies traded on foreign exchanges that are open on days the NYSE
is closed.

In determining NAV, portfolio investments are valued at market value.
Investments for which quotations are not readily available are valued at fair
value determined in good faith under the supervision of the Board of Trustees.

CLASS A SALES CHARGE REDUCTIONS AND WAIVERS

YOU CAN LOWER THE SALES CHARGE PERCENTAGE IN FOUR WAYS:

/bullet/ Substantial investments receive lower sales charge rates; see the table
below _______.

/bullet/ The "right of accumulation" allows you to include your existing Class A
         Shares (or Class T shares of the Growth Fund) as part of your current
         investments for sales charge purposes.

/bullet/ A "letter of intent" allows you to count all Class A share investments
         in an IDEX Fund over the next 13 months, as if you were making them all
         at once, to qualify for a reduced sales charge. 

/bullet/ By investing as part of a qualified group.

instructions which are believed by the Fund, ISI and IDEX to be genuine. The

has the right to modify the telephone redemption privilege.

In most cases, the Fund can send your redemption money via Federal Funds bank
wire. IDEX charges a $10 fee for this service, in addition to any fee your bank
may charge. For more details, call Customer Service or see the SAI.

REINVESTMENT PRIVILEGE

Within a 90 day period after you sell your Class A, B or C shares, you have the
right to "reinvest" your shares in any Fund of the same class. You will not
incur a new sales charge by using this privilege within the allotted time frame.
Any CDSC you paid on Class B or C shares will be credited to your account. You
may reinvest the proceeds of a Class B share sale (less the sales charge) in
Class A shares without paying the up-front sales charge. Send your written
request to IDEX along with your check for your reinvestment privilege.

STATEMENTS AND REPORTS

The Fund will send you a confirmation statement after every transaction that
affects your account balance or registration. If you are enrolled in the
Automatic Investment Plan and invest on a monthly basis, you will receive a
quarterly confirmation. Information about the tax status of income dividends and
capital gains distributions will be mailed to shareholders early each year.

Financial reports for the Funds, which include a list of the holdings, will be
mailed twice a year to all shareholders.

A Historical Statement may be ordered for transactions of prior years.

SHARE CERTIFICATES

The majority of shareholders prefer their shares to be recorded on the Fund's
books and no certificates issued.

If you would like certificates representing your shares, call or write IDEX to
request them. You may return share certificates to IDEX for re-deposit at any
time. If your share certificates are lost or stolen, notify IDEX immediately.
There may be a charge for canceling and replacing lost or stolen share
certificates. Remember, if you ask for a certificate for your shares, you will
not be able to redeem or exchange your shares by telephone. You will have to
send your share certificates to IDEX in order to redeem or exchange your shares.
Share certificates can be issued with the following limitations:

         sales or transfers from other funds that you have certificates issued

         Fiduciary Trust as custodian

PERSONAL SECURITIES TRADING

The Fund permits "Access Persons" as defined by Rule 17j-1 under the 1940 Act to
engage in personal securities transactions, subject to the terms of the Code of
Ethics and Insider Trading Policy that has been adopted by the Board of Trustees
of the Fund. Access Persons must use the guidelines established by this Policy
for all personal securities transactions and are subject to certain prohibitions
on personal trading. The Fund's sub-advisers, pursuant to Rule 17j-1 and other
applicable laws, and pursuant to the terms of the Policy, must adopt and enforce
their own Code of Ethics and Insider Trading Policies appropriate to their
particular business needs. Each sub-adviser must report to the Board of Trustees
on a quarterly basis with respect to the administration and enforcement of such
Policy, including any violations thereof which may potentially affect the Fund.

[GRAPHIC OMITTED] DISTRIBUTION AND TAXES

The Fund may make distributions generally, in the form of income dividends,
exempt-interest dividends (dividends that are not subject to federal tax) and
capital gains. Distributions will be reinvested in, unless you request cash
payment.

For taxable accounts, income dividends and short-term capital gains are taxable
as "ordinary dividends." Ordinary dividends and capital gain distributions are
taxable whether reinvested in your account or paid in cash.

When you redeem or exchange shares, if you realize a gain you will owe taxes,
unless your account is a tax-qualified retirement plan. If the sale or exchange
produces a loss, you may be able to use the loss to offset taxable gains. Tax
forms and/or Statements showing taxable transactions for the calendar year are
mailed by January 31 of the next year.

The foregoing information is not tax advice. Consult your tax advisor about tax
consequences for your personal situation.

The Tax-Exempt Fund may invest in securities that generate income that is not
exempt from federal or state income tax. Income exempt from federal tax may be
subject to state and local tax. Capital gains distributed by the Fund may be
taxable.

DISTRIBUTION ARRANGEMENTS


[GRAPHIC OMITTED] UNDERWRITING AGREEMENT
[GRAPHIC OMITTED]

IDEX Mutual Funds has an Underwriting Agreement with ISI, a registered
broker/dealer. Under this agreement, ISI underwrites and distributes all three
classes of Fund shares and bears the expenses of offering these shares to the
public. The Funds pay ISI fees for its services.

Of the distribution and service fees it receives for Class A and B shares, ISI
reallows, or pays, to brokers or dealers who sold them, 0.25% of the average
daily net assets of those shares. In the case of Class C shares, ISI reallows
its entire fee to those sellers.

[GRAPHIC OMITTED] DISTRIBUTION PLANS

DISTRIBUTION OF CLASS A SHARES. ISI receives the sales fees or loads imposed on
these shares (up to 5.5% of the offering price, which includes the sales load)
and reallows a portion of those fees to the sellers of the shares. ISI also
receives fees under a Rule 12b-1 Plan of Distribution. Under its Plan for Class
A shares, the Funds may pay ISI a distribution fee of up to 0.35% annually and a
service fee of 0.25%. Fees are based on the average daily net assets of Class A
shares. However, if the service fees rise, the distribution fee is lowered so
that the total fees payable don't exceed 0.35% annually.

DISTRIBUTION OF CLASS B SHARES. For these shares, the Funds may pay ISI an
annual distribution fee of up to 0.75% and an annual service fee of 0.25%.

DISTRIBUTION OF CLASS C SHARES. The fees paid to ISI for these shares may go as
high as for Class B (O.75% and 0.25%), but the total annual fee may not exceed
0.90% of the average daily net assets of the funds.

GROWTH FUND CLASS T SHARES. This class of shares does not have a 12b-1 Plan of
Distribution, and is closed to new shareholders.

THE EFFECT OF RULE 12b-1. Because these Funds have a 12b-1 Plan, even though
Class B shares don't carry an up-front sales load, the higher distribution and
service fees payable by those shares may, over time, be higher than the total
fees paid by owners of A shares. For a complete description of the Funds' 12b-1
Plans, see the SAI.

PREPARING FOR YEAR 2000

Like all financial service providers, the Fund and the investment adviser
utilize systems that may be affected by Year 2000 transition issues. The Fund
also relies on service providers, including the Fund's custodian and the
sub-advisers, which may be affected. The Fund and the investment adviser have
developed, and are in the process of implementing, a Year 2000 transition plan.
Management of the Fund is in the process of confirming that the service
providers to the Fund are also engaged in similar transition plans.

While the investment adviser and each sub-adviser has made a representation to
Management that each party is implementing a Year 2000 transition plan, the
resources that are being devoted to this effort are substantial and it is
difficult to predict with precision whether the amount of resources ultimately
devoted, or the outcome of these efforts, will have any negative impact on the
Fund or the investment adviser. If systems of the investment adviser,
sub-advisers, or other service providers fail at Year 2000, the Funds could be
unable to process portfolio or shareholder transactions or provide accurate
_______ to investors.

The Fund and the investment adviser currently anticipate that their systems will
be Year 2000 compliant prior to the end of 1999, but there can be no assurance
that the Fund or investment adviser will be successful, or that interaction with
other service providers will not impair the Funds or investment advisers
services in year 2000.

                              INVESTMENT OBJECTIVES

   
      The Prospectus discusses the investment objective of each Fund of the IDEX
Mutual Funds, the principal types of securities in which each Fund will invest,
and the policies and practices of each Fund. The following discussion of
Investment Restrictions, Policies and Practices supplements that set forth in
the Prospectus.

      There can be no assurance that a Fund will, in fact, achieve its
objective. A Fund's investment objective may be changed by the Board of Trustees
without shareholder approval. A change in the investment objective of a Fund may
result in the Fund having an investment objective different from that which the
shareholder deemed appropriate at the time of investment. A Fund will not change
its objective without 30 days prior notice to its shareholders, nor will it
charge shareholders an exchange fee or redemption fee after such notice and
prior to the expiration of such 30-day notice period. However, should a
shareholder decide to redeem Fund shares because of a change in the objective,
the shareholder may realize a taxable gain or loss.
    

                 INVESTMENT RESTRICTIONS, POLICIES AND PRACTICES

      As indicated in the Prospectus, each Fund is subject to certain
fundamental policies and restrictions which as such may not be changed without
shareholder approval. Shareholder approval would be the approval by the lesser
of (i) more than 50% of the outstanding voting securities of a Fund, or (ii) 67%
or more of the voting securities present at a meeting if the holders of more
than 50% of the outstanding voting securities of a Fund are present or
represented by proxy.

INVESTMENT RESTRICTIONS OF IDEX AGGRESSIVE GROWTH FUND

IDEX Aggressive Growth Fund may not, as a matter of fundamental policy:

      1. With respect to 75% of the Fund's total assets, purchase the securities
of any one issuer (other than government securities as defined in the Investment
Company Act of 1940, as amended (the "1940 Act")), if immediately after and as a
result of such purchase (a) the value of the holdings of the Fund in the
securities of such issuer exceeds 5% of the value of the Fund's total assets, or
(b) the Fund owns more than 10% of the outstanding voting securities of any one
class of securities of such issuer;

      2. Purchase any securities that would cause more than 25% of the value of
the Fund's total assets to be invested in the securities of issuers conducting
their principal business activities in the same industry; provided that there
shall be no limit on the purchase of U.S. government securities;

      3. Purchase or sell real estate or real estate limited partnerships,
except that the Fund may purchase and sell securities secured by real estate,
mortgages or interests therein and securities that are issued by companies that
invest or deal in real estate;

      4. Invest in commodities, except that the Fund may purchase or sell stock
index futures contracts and related options thereon if thereafter no more than
5% of its total assets are invested in aggregate initial margin and premiums;

      5. Make loans to others, except through purchasing qualified debt
obligations, lending Fund securities or entering into repurchase agreements;

      6. Act as an underwriter of securities issued by others, except to the
extent that it may be deemed an underwriter in connection with the disposition
of its Fund securities;

      7. Borrow money, except that the Fund may borrow from banks for investment
purposes as set forth in the Prospectus and may also engage in reverse
repurchase agreements. Immediately after any borrowing, including reverse
repurchase agreements, the Fund will maintain asset coverage of not less than
300% with respect to all borrowings; and

      8. Issue senior securities, except that the Fund may borrow from banks for
investment purposes so long as the Fund maintains the required coverage.

                                       1

<PAGE>


      Furthermore, the Fund has adopted the following non-fundamental investment
restrictions which may be changed by the Board of Trustees of the Funds without
shareholder approval:

      (A) The Fund may not sell securities short or purchase securities on
margin, except that the Fund may obtain any short-term credit necessary for the
clearance of purchases and sales of securities. These restrictions shall not
apply to transactions involving selling securities "short against the box";

      (B) The Fund may not pledge, hypothecate, mortgage or otherwise encumber
more than 15% of the value of the Fund's total assets except in connection with
borrowings described in number 7 above. These restrictions shall not apply to
transactions involving reverse repurchase agreements or the purchase of
securities subject to firm commitment agreements or on a when-issued basis;

      (C) The Fund may not invest directly in oil, gas, or other mineral
development or exploration programs or leases; however, the Fund may own debt or
equity securities of companies engaged in those businesses;

      (D) The Fund may not (i) purchase securities of other investment
companies, except in the open market where no commission except the ordinary
broker's commission is paid, or (ii) purchase or retain securities issued by
other open-end investment companies. Limitations (i) and (ii) do not apply to

securities;

      12. Invest in securities of other investment companies, except in the

securities;

      7. Invest in securities of other investment companies, except in the event

constitute borrowings.

               delivery or purchase obligations in excess of 30% of the Fund's
               net assets, and

           (2) the purchase of put and call options related to portfolio
               securities and securities to be purchased for the Tax-Exempt

               contract margin deposits and premiums on option purchases which,
               in the aggregate, exceed 5% of the Fund's net assets, in the
               judgment of the sub-adviser are economically appropriate to the
               reduction of risks inherent in the ongoing management of the
               Fund, and are executed under custodial, reserve and other
               arrangements consistent with regulations and policies adopted or
               positions taken (i) by the Securities and Exchange Commission for

               the Fund's shares have been qualified for public offering.

assets for temporary purposes, (c) the Fund may obtain such short-term credits
as may be necessary for the clearance of purchases and sales of Fund securities,
(d) the Fund may purchase securities on margin to the extent permitted by
applicable law and (e) the Fund may engage in mortgage dollar rolls which are

      3. Purchase or sell physical commodities (but this shall not prevent the
Fund from investing in currency and financial instruments and contracts that are
commodities or commodity contracts).

      4. Invest more than 25% of the Fund's assets in the securities of issuers
primarily engaged in the same industry. Utilities will be divided according to
their services; for example, gas, gas transmission, electric and telephone, and
each will be considered a separate industry for purposes of this restriction,
provided that there shall be no limitation on the purchase of obligations issued
or guaranteed by the U.S. Government or its agencies or instrumentalities, or of

INVESTMENT RESTRICTIONS OF IDEX DIVIDEND GROWTH FUND

The Fund may not, as a matter of fundamental policy:

      1. With respect to 75% of the Fund's total assets, purchase the securities
of any one issuer (other than Government securities as defined in the 1940 Act)

voting securities of any one class of securities of such issuer.

      2. Borrow money except for temporary or emergency purposes (not for
leveraging or investment) in an amount exceeding 33-1/3% of the value of the

business days to the extent necessary to comply with the 33-1/3% limitation.
This policy shall not prohibit reverse repurchase agreements or deposits of
assets to margin or guarantee positions in futures, options, swaps or forward

that the aggregate of such loans do not exceed 33-1/3% of the value of the
Fund's total assets. The Fund may purchase money market securities, enter into
repurchase agreements and acquire publicly distributed or privately placed debt
securities, and purchase debt.

      6. Purchase or sell real estate (but this shall not prevent the Fund from
investing in securities or other instruments backed by real estate, including
mortgage-backed securities, or securities of companies engaged in the real
estate business).

restrictions which may be changed by the Board of Trustees of the Fund without
shareholder approval:

      (A) The Fund may not purchase additional securities when money borrowed

of Additional Information.

      4. Purchase or sell real estate, real estate limited partnership
interests, futures contracts, commodities or commodity contracts, except that
this shall not prevent the Fund from (i) investing in readily marketable
securities of issuers which can invest in real estate or commodities,
institutions that issue mortgages, or real estate investment trusts which deal
in real estate or interests therein, pursuant to the Fund's investment objective
and policies, and (ii) entering into futures contracts and options thereon that
are listed on a national securities or commodities exchange where, as a result
thereof, no more than 5% of the Fund's total assets (taken at market value at
the time of entering into the futures contracts) would be committed to margin
deposits on such futures contracts and premiums paid for unexpired options on
such futures contracts; provided that, in the case of an option that is
"in-the-money" at the time of purchase, the "in-the-money" amount, as defined
under the Commodities Futures Trading Commission regulations, may be excluded in
computing the 5% limit. The Fund (as a matter of operating policy) will utilize
only listed futures contracts and options thereon.

      5. Act as an underwriter of securities of other issuers except as it may
be deemed an underwriter in selling a Fund security.

made a determination as to liquidity, as permitted under the 1940 Act.

      (D) The Fund may not purchase securities of other investment companies
except as permitted by the 1940 Act and the rules and regulations thereunder.

INVESTMENT RESTRICTIONS OF IDEX SMALL CAP FRONTIER FUND

restriction, provided that there shall be no limitation on the purchase of
obligations issued or guaranteed by the U.S. Government or its agencies or
instrumentalities, or of certificates of deposit and bankers' acceptances.

      5. Lend any security although the Fund may lend Fund securities provided

      Except with respect to borrowing money, if a percentage limitation set
forth above is complied with at the time of the investment, a subsequent change
in the percentage resulting from any change in value of the net assets of any of
the Funds will not result in a violation of such restriction. Additional
limitations on borrowing that are imposed by state law and regulations may

other than the Tax-Exempt Fund and the Income Plus Fund, may, notwithstanding
any other investment policy or limitation (whether or not fundamental), invest
all of its assets in the securities of a single open-end management investment
company with substantially the same fundamental investment objectives, policies
and limitations as such Fund.
    

                    OTHER POLICIES AND PRACTICES OF THE FUNDS

FUTURES, OPTIONS AND OTHER DERIVATIVE INSTRUMENTS.

   
The following investments are subject to limitations as set forth in each
Fund's investment restrictions and policies:

      A.   FUTURES CONTRACTS. A Fund may enter into futures contracts. Futures
           contracts are for the purchase or sale, for future delivery, of
           equity or fixed-income securities, foreign currencies or contracts
           based on financial indices, including indices of U.S. government
           securities, foreign government securities and equity or fixed-income
           securities. The Income Plus Fund may enter into interest rate futures
           contracts. These contracts are for the purchase or sale of
           fixed-income securities. U.S. futures contracts are traded on
           exchanges which have been designated "contract markets" by the
           Commodity Futures Trading Commission ("CFTC") and must be executed
           through a Futures Trading Commission merchant ("FCM"), or brokerage
           firm, which is a member of the relevant contract market. Through
           their clearing corporations, the exchanges guarantee performance of
           the contracts as between the clearing members of the exchange.

           When a Fund buys or sells a futures contract, it must receive or
           deliver the underlying instrument (or a cash payment based on the
           difference between the underlying instrument's closing price and the
           price at which the contract was

                                       22

<PAGE>

           entered into) at a specified price on a specified date. Transactions
           in futures contracts may be made to attempt to hedge against
           potential changes in interest or currency exchange rates, or the
           price of a security or a securities index which might correlate with,
           or otherwise adversely affect, either the value of the Fund's
           securities or the prices of securities which the Fund is considering
           buying at a later date.
    
           The buyer or seller of a futures contract is not required to deliver
           or pay for the underlying instrument unless the contract is held
           until the delivery date. However, both the buyer and seller are
           required to deposit "initial margin" for the benefit of the FCM when
           the contract is entered into. Initial margin deposits are equal to a
           percentage of the contract's value, as set by the exchange on which
           the contract is traded, and may be maintained in cash or liquid
           assets by the Fund's custodian for the benefit of the FCM. Initial
           margin payments are similar to good faith deposits or performance
           bonds.

           Unlike margin extended by a securities broker, initial margin
           payments do not constitute purchasing securities on margin for
           purposes of a Fund's investment limitations. If the value of either
           party's position declines, that party will be required to make
           additional "variation margin" payments with the FCM to settle the
           change in value on a daily basis. The party that has a gain may be
           entitled to receive all or a portion of this amount. In the event of
           the bankruptcy of the FCM that holds margin on behalf of a Fund, that
           Fund may be entitled to return of the margin owed to such Fund only
           in proportion to the amount received by the FCM's other customers.
           The Fund's sub-adviser will attempt to minimize the risk by careful
           monitoring of the creditworthiness of the FCMs with which a Fund does
           business and by segregating margin payments with the custodian.
   
           Although a Fund would segregate with the custodian cash and liquid
           assets in an amount sufficient to cover its open futures obligations,
           the segregated assets would be available to that Fund immediately
           upon closing out the futures position, while settlement of securities
           transactions could take several days. However, because a Fund's cash
           that may otherwise be invested would be held uninvested or invested
           in liquid assets so long as the futures position remains open, such
           Fund's return could be diminished due to the opportunity losses of
           foregoing other potential investments.

           The acquisition or sale of a futures contract may occur, for example,
           when a Fund holds or is considering purchasing equity or debt
           securities and seeks to protect itself from fluctuations in prices or
           interest rates without buying or selling those securities. For
           example, if stock or debt prices were expected to decrease, a Fund
           might sell equity index futures contracts, thereby hoping to offset a
           potential decline in the value of equity securities in the Fund by a
           corresponding increase in the value of the futures contract position
           held by that Fund and thereby preventing the Fund's net asset value
           from declining as much as it otherwise would have.

           Similarly, if interest rates were expected to rise, a Fund might sell
           bond index futures contracts, thereby hoping to offset a potential
           decline in the value of debt securities in the Fund by a
           corresponding increase in the value of the futures contract position
           held by the Fund. A Fund also could seek to protect against potential
           price declines by selling Fund securities and investing in money
           market instruments. However, since the futures market is more liquid
           than the cash market, the use of futures contracts as an investment
           technique allows a Fund to maintain a defensive position without
           having to sell Fund securities.

           Likewise, when prices of equity securities are expected to increase,
           or interest rates are expected to fall, futures contracts may be
           bought to attempt to hedge against the possibility of having to buy
           equity securities at higher prices. This technique is sometimes known
           as an anticipatory hedge. Since the fluctuations in the value of
           futures contracts should be similar to those of equity securities, a
           Fund could take advantage of the potential rise in the value of
           equity or debt securities without buying them until the market has
           stabilized. At that time, the futures contracts could be liquidated
           and such Fund could buy equity or debt securities on the cash market.
           To the extent a Fund enters into futures contracts for this purpose,
           the segregated assets maintained to cover such Fund's obligations
           (with respect to futures contracts) will consist of liquid assets
           from its portfolio in an amount equal to the difference between the
           contract price and the aggregate value of the initial and variation
           margin payments made by that Fund.
    

           The ordinary spreads between prices in the cash and futures markets,
           due to differences in the nature of those markets, are subject to
           distortions:


                                       23

<PAGE>

  /diamond/    First, all participants in the futures market are subject to
               initial margin and variation margin requirements. Rather than
               meeting additional variation margin requirements, investors may
               close out futures contracts through offsetting transactions which
               could distort the normal price relationship between the cash and
               futures markets.

  /diamond/    Second, the liquidity of the futures market depends on
               participants entering into offsetting transactions rather than
               making or taking delivery. To the extent participants decide to
               make or take delivery, liquidity in the futures market could be
               reduced and prices in the futures market distorted.

  /diamond/    Third, from the point of view of speculators, the margin deposit
               requirements in the futures market are less onerous than margin
               requirements in the securities market. Therefore, increased
               participation by speculators in the futures market may cause
               temporary price distortions.

           Due to the possibility of the foregoing distortions, a correct
           forecast of general price trends by the Fund manager still may not
           result in a successful use of futures contracts.
   
           Futures contracts entail risks. Although each of the Funds that
           invests in such contracts believes that their use will benefit the
           Fund, if the Fund sub-adviser's investment judgment proves incorrect,
           the Fund's overall performance could be worse than if the Fund had
           not entered into futures contracts.

           For example, if a Fund has hedged against the effects of a possible
           decrease in prices of securities held in its Fund and prices increase
           instead, that Fund may lose part or all of the benefit of the
           increased value of the securities because of offsetting losses in the
           Fund's futures positions. In addition, if a Fund has insufficient
           cash, it may have to sell securities from its Fund to meet daily
           variation margin requirements. Those sales may, but will not
           necessarily, be at increased prices which reflect the rising market
           and may occur at a time when the sales are disadvantageous to the
           Fund.

           The prices of futures contracts depend primarily on the value of
           their underlying instruments. Because there are a limited number of
           types of futures contracts, it is possible that the standardized
           futures contracts available to a Fund will not exactly match that
           Fund's current or potential investments. A Fund may buy and sell
           futures contracts based on underlying instruments with different
           characteristics from the securities in which it typically invests.
           For example, by hedging investments in Fund securities with a futures
           contract based on a broad index of securities may involve a risk that
           the futures position will not correlate precisely with such
           performance of the Fund's investments.

           Futures prices can also diverge from the prices of their underlying
           instruments, even if the underlying instruments correlate with a
           Fund's investments. Futures prices are affected by factors such as:
           current and anticipated short-term interest rates; changes in
           volatility of the underlying instruments; and the time remaining
           until expiration of the contract. Those factors may affect securities
           prices differently from futures prices.

           Imperfect correlations between a Fund's investments and its futures
           positions may also result from: differing levels of demand in the
           futures markets and the securities markets; from structural
           differences in how futures and securities are traded; and from
           imposition of daily price fluctuation limits for futures contracts.

           A Fund may buy or sell futures contracts with a greater or lesser
           value than the securities it wishes to hedge or is considering
           purchasing in order to attempt to compensate for differences in
           historical volatility between the futures contract and the
           securities. This may not be successful in all cases. If price changes
           in a Fund's futures positions are poorly correlated with its other
           investments, its futures positions may fail to produce desired gains
           or may result in losses that are not offset by the gains in that
           Fund's other investments.
    
           Because futures contracts are generally settled within a day from the
           date they are closed out, compared with a settlement period of seven
           days for some types of securities, the futures markets can provide
           superior liquidity to the securities markets. Nevertheless, there is
           no assurance a liquid secondary market will exist for any particular
           futures contract at any particular time.

                                       24
<PAGE>
   
           In addition, futures exchanges may establish daily price fluctuation
           limits for futures contracts and may halt trading if a contract's
           price moves upward or downward more than the limit in a given day. On
           volatile trading days when the price fluctuation limit is reached, it
           may be impossible for a Fund to enter into new positions or close out
           existing positions. If the secondary market for a futures contract is
           not liquid because of price fluctuation limits or otherwise, the Fund
           may not be able to promptly liquidate unfavorable futures positions
           and potentially could be required to continue to hold a futures
           position until the delivery date, regardless of changes in its value.
           As a result, such Fund's access to other assets held to cover its
           futures positions also could be impaired.
    
           Although futures contracts by their terms call for the delivery or
           acquisition of the underlying commodities, or a cash payment based on
           the value of the underlying commodities, in most cases the
           contractual obligation is offset before the delivery date of the
           contract. This is accomplished by buying, in the case of a
           contractual obligation to sell, or selling, in the case of a
           contractual obligation to buy, an identical futures contract on a
           commodities exchange. Such a transaction cancels the obligation to
           make or take delivery of the commodities.
   
           If applicable each Fund intends to comply with guidelines of
           eligibility for exclusion from the definition of the term "commodity
           pool operator" with the CFTC and the National Futures Association,
           which regulate trading in the futures markets. The Funds will use
           futures contracts and related options primarily for bona fide hedging
           purposes within the meaning of CFTC regulations. In addition, the
           Funds may hold positions in futures contracts and related options
           that do not fall within the definition of bona fide hedging
           transactions, provided that the aggregate initial margin and premiums
           required to establish such positions will not exceed 5% of the fair
           market value of a Fund's net assets, after taking into account
           unrealized profits and unrealized losses on any such contracts it has
           entered into.

           The Aggressive Growth Fund may not enter into a futures contract or
           related option (except for closing transactions) if, immediately
           thereafter, the sum of the amount of its initial margin and premiums
           on open futures contracts and options thereon would exceed 5% of the
           Aggressive Growth Fund's total assets (taken at current value);
           however, in the case of an option that is in-the-money at the time of
           the purchase, the in-the-money amount may be excluded in calculating
           the 5% limitation.

      B.   OPTIONS ON FUTURES CONTRACTS. A Fund may buy and write put and call
           options on futures contracts. An option on a futures contract gives a
           Fund the right (but not the obligation) to buy or sell the contract
           at a specified price on or before a specified date. Transactions in
           options on futures contracts may be made to attempt to hedge against
           potential changes in interest rates or currency exchange rates, or
           the price of a security or a securities index which might correlate
           with, or otherwise adversely affect, either the value of the Fund's
           securities or the prices of securities which the Fund is considering
           buying at a later date. Transactions in options on future contracts
           will not be made for speculation.

           The purchase of a call option on a futures contract is similar in
           some respects to the purchase of a call option on an individual
           security. Depending on the pricing of the option compared to either
           the price of the futures contract upon which it is based or the price
           of the underlying instrument, ownership of the option may or may not
           be less risky than ownership of the futures contract or the
           underlying instrument. As with the purchase of futures contracts,
           when a Fund is not fully invested it may buy a call option on a
           futures contract to hedge against a market advance.

           The writing of a call option on a futures contract constitutes a
           partial hedge against declining prices of the security or foreign
           currency which is deliverable under, or of the index comprising, the
           futures contract. If the futures price at the expiration of the
           option is below the exercise price, a Fund will retain the full
           amount of the option premium which provides a partial hedge against
           any decline that may have occurred in such Fund's holdings.

           The writing of a put option on a futures contract constitutes a
           partial hedge against increasing prices of the security or foreign
           currency which is deliverable under, or of the index comprising, the
           futures contract. If the futures price at expiration of the option is
           higher than the exercise price, a Fund will retain the full amount of
           the option premium which provides a partial hedge against any
           increase in the price of securities which that Fund is considering
           buying.

                                       25
<PAGE>

           If a call or put option a Fund has written is exercised, such Fund
           will incur a loss which will be reduced by the amount of the premium
           it received. Depending on the degree of correlation between the
           change in the value of its Fund securities and changes in the value
           of the futures positions, that Fund's losses from existing options on
           futures may to some extent be reduced or increased by changes in the
           value of Fund securities.

           The purchase of a put option on a futures contract is similar in some
           respects to the purchase of protective put options on Fund
           securities. For example, a Fund may buy a put option on a futures
           contract to hedge its Fund securities against the risk of falling
           prices or rising interest rates.

           The amount of risk a Fund assumes when it buys an option on a futures
           contract is the premium paid for the option plus related transaction
           costs. In addition to the correlation risks discussed above, the
           purchase of an option also entails the risk that changes in the value
           of the underlying futures contract will not be fully reflected in the
           value of the options bought.

      C.   OPTIONS ON SECURITIES. In an effort to increase current income and to
           reduce fluctuations in net asset value, each of the Funds, other than
           the Tax-Exempt and the Income Plus Funds, may write covered put and
           call options and buy put and call options on securities that are
           traded on United States and foreign securities exchanges, and
           over-the-counter. A Fund also may write call options that are not
           covered for cross-hedging purposes. A Fund may write and buy options
           on the same types of securities that the Fund may purchase directly.
           There are no specific limitations on a Fund's writing and buying of
           options on securities.
    
           A put option gives the holder the right, upon payment of a premium,
           to deliver a specified amount of a security to the writer of the
           option on or before a fixed date at a predetermined price. A call
           option gives the holder the right, upon payment of a premium, to call
           upon the writer to deliver a specified amount of a security on or
           before a fixed date at a predetermined price.

   
           A put option written by a Fund is "covered" if the Fund: (i)
           segregates cash not available for investment or other liquid assets
           with a value equal to the exercise price with its custodian; or (ii)
           continues to own an equivalent number of puts of the same "series"
           (that is, puts on the same underlying securities having the same
           exercise prices and expiration dates as those written by the Fund),
           or an equivalent number of puts of the same "class" (that is, puts on
           the same underlying securities) with exercise prices greater than
           those it has written (or if the exercise prices of the puts it holds
           are less than the exercise prices of those it has written, the
           difference is segregated with the custodian).
    
            The premium paid by the buyer of an option will reflect, among other
           things, the relationship of the exercise price to the market price
           and the volatility of the underlying security, the remaining term of
           the option, supply and demand and interest rates.
   
           A call option written by a Fund is "covered" if the Fund owns the
           underlying security covered by the call or has an absolute and
           immediate right to acquire that security without additional cash
           consideration (or has segregated additional cash with its custodian)
           upon conversion or exchange of other securities held in its Fund. A
           call option written by a Fund is also deemed to be covered: (i) if
           that Fund holds a call at the same exercise price for the same
           exercise period and on the same securities as the call written; (ii)
           in the case of a call on a stock index, if the Fund owns a Fund of
           securities substantially replicating the movement of the index
           underlying the call option; or (iii) if at the time the call is
           written an amount of cash, U.S. government securities or other liquid
           assets equal to the fluctuating market value of the optioned
           securities is segregated with the custodian.

           A Fund may also write call options that are not covered for
           cross-hedging purposes. A Fund collateralizes its obligation under a
           written call option for cross-hedging purposes by segregating cash or
           other liquid assets in an amount not less than the market value of
           the underlying security, marked-to-market daily. A Fund would write a
           call option for cross-hedging purposes, instead of writing a covered
           call option, when the premium to be received from the cross-hedge
           transaction would exceed that which would be received from writing a
           covered call option and the Fund manager believes that writing the
           option would achieve the desired hedge.

                                       26

<PAGE>

           If a put or call option written by a Fund were exercised, the Fund
           would be obligated to buy or sell the underlying security at the
           exercise price. Writing a put option involves the risk of a decrease
           in the market value of the underlying security, in which case the
           option could be exercised and the underlying security would then be
           sold by the option holder to the Fund at a higher price than its
           current market value. Writing a call option involves the risk of an
           increase in the market value of the underlying security, in which
           case the option could be exercised and the underlying security would
           then be sold by the Fund to the option holder at a lower price than
           its current market value. Those risks could be reduced by entering
           into an offsetting transaction. A Fund retains the premium received
           from writing a put or call option whether or not the option is
           exercised.
    

           The writer of an option may have no control when the underlying
           security must be sold, in the case of a call option, or bought, in
           the case of a put option, since with regard to certain options, the
           writer may be assigned an exercise notice at any time prior to the
           termination of the obligation. Whether or not an option expires
           unexercised, the writer retains the amount of the premium.

           This amount, of course, may, in the case of a covered call option, be
           offset by a decline in the market value of the underlying security
           during the option period. If a call option is exercised, the writer
           experiences a profit or loss from the sale of the underlying
           security. If a put option is exercised, the writer must fulfill the
           obligation to buy the underlying security at the exercise price,
           which will usually exceed the then market value of the underlying
           security.

           The writer of an option that wishes to terminate its obligation may
           effect a "closing purchase transaction." This is accomplished by
           buying an option of the same series as the option previously written.
           The effect of the purchase is that the writer's position will be
           canceled by the clearing corporation. However, a writer may not
           effect a closing purchase transaction after being notified of the
           exercise of an option. Likewise, an investor who is the holder of an
           option may liquidate its position by effecting a "closing sale
           transaction." This is accomplished by selling an option of the same
           series as the option previously bought. There is no guarantee that
           either a closing purchase or a closing sale transaction can be
           effected.
   
           In the case of a written call option, effecting a closing transaction
           will permit a Fund to write another call option on the underlying
           security with either a different exercise price or expiration date or
           both. In the case of a written put option, such transaction will
           permit the Fund to write another put option to the extent that the
           exercise price thereof is secured by deposited other liquid assets.
           Effecting a closing transaction also will permit the cash or proceeds
           from the concurrent sale of any securities subject to the option to
           be used for other Fund investments. If a Fund desires to sell a
           particular security on which the Fund has written a call option, such
           Fund will effect a closing transaction prior to or concurrent with
           the sale of the security.

           A Fund will realize a profit from a closing transaction if the price
           of a purchase transaction is less than the premium received from
           writing the option or the price received from a sale transaction is
           more than the premium paid to buy the option. The Fund will realize a
           loss from a closing transaction if the price of the purchase
           transaction is more than the premium received from writing the option
           or the price received from a sale transaction is less than the
           premium paid to buy the option. Because increases in the market price
           of a call option will generally reflect increases in the market price
           of the underlying security, any loss resulting from the repurchase of
           a call option is likely to be offset in whole or in part by
           appreciation of the underlying security owned by the Fund.
    

           An option position may be closed out only where a secondary market
           for an option of the same series exists. If a secondary market does
           not exist, a Fund may not be able to effect closing transactions in
           particular options and that Fund would have to exercise the options
           in order to realize any profit. If a Fund is unable to effect a
           closing purchase transaction in a secondary market, it will not be
           able to sell the underlying security until the option expires or it
           delivers the underlying security upon exercise. Reasons for the
           absence of a liquid secondary market may include the following: (i)
           there may be insufficient trading interest in certain options; (ii)
           restrictions may be imposed by a national securities exchange on
           which the option is traded ("Exchange") on opening or closing
           transactions or both; (iii) trading halts, suspensions or other
           restrictions may be imposed with respect to particular classes or
           series of options or underlying securities; (iv) unusual or
           unforeseen circumstances may interrupt normal operations on an
           Exchange; (v) the facilities of an Exchange or the Options Clearing
           Corporation ("OCC") may not at all times be adequate to handle
           current trading volume; or (vi) one or more Exchanges could, for 
           economic or other reasons, decide or be compelled at some future date
           to discontinue the trading of options (or a particular class or 
           series of options). In that case, the secondary market on that 
           Exchange (or in that class or series of options) would cease to 
           exist, although outstanding options on that Exchange that had been 
           issued by the OCC as a result of trades on that Exchange would 
           continue to be exercisable in accordance with their terms.
   
           Each of the Funds, other than the Tax-Exempt and the Income Plus
           Funds, may write options in connection with buy-and-write
           transactions. In other words, the Fund may buy a security and then
           write a call option against that security. The exercise price of such
           call will depend upon the expected price movement of the underlying
           security. The exercise price of a call option may be below
           ("in-the-money"), equal to ("at-the-money"), or above
           ("out-of-the-money") the current value of the underlying security at
           the time the option is written.
    
           Buy-and-write transactions using in-the-money call options may be
           used when it is expected that the price of the underlying security
           will remain flat or decline moderately during the option period.
           Buy-and-write transactions using at-the-money call options may be
           used when it is expected that the price of the underlying security
           will remain fixed or advance moderately during the option period.
           Buy-and-write transactions using out-of-the-money call options may be
           used when it is expected that the premiums received from writing the
           call option plus the appreciation in the market price of the
           underlying security up to the exercise price will be greater than the
           appreciation in the price of the underlying security alone.
   
           If the call options are exercised in such transactions, the Fund's
           maximum gain will be the premium received by it for writing the
           option, adjusted upwards or downwards by the difference between that
           Fund's purchase price of the security and the exercise price. If the
           options are not exercised and the price of the underlying security
           declines, the amount of such decline will be offset by the amount of
           premium received.
    
           The writing of covered put options is similar in terms of risk and
           return characteristics to buy-and-write transactions. If the market
           price of the underlying security rises or otherwise is above the
           exercise price, the put option will expire worthless and a Fund's
           gain will be limited to the premium received. If the market price of
           the underlying security declines or otherwise is below the exercise
           price, a Fund may elect to close the position or take delivery of the
           security at the exercise price and that Fund's return will be the
           premium received from the put options minus the amount by which the
           market price of the security is below the exercise price.
   
           A Fund may buy put options to hedge against a decline in the value of
           its Fund. By using put options in this way, a Fund will reduce any
           profit it might otherwise have realized in the underlying security by
           the amount of the premium paid for the put option and by transaction
           costs.

           A Fund may buy call options to hedge against an increase in the price
           of securities that it may buy in the future. The premium paid for the
           call option plus any transaction costs will reduce the benefit, if
           any, realized by such Fund upon exercise of the option, and, unless
           the price of the underlying security rises sufficiently, the option
           may expire worthless to that Fund.

           In purchasing an option, a Fund would be in a position to realize a
           gain if, during the option period, the price of the underlying
           security increased (in the case of a call) or decreased (in the case
           of a put) by an amount in excess of the premium paid. The Fund would
           realize a loss if the price of the underlying security did not
           increase (in the case of a call) or decrease (in the case of a put)
           during the period by more than the amount of the premium. If a put or
           call option purchased by a Fund were permitted to expire without
           being sold or exercised, the Fund would lose the amount of the
           premium.
    
           Although they entitle the holder to buy equity securities, warrants
           on and options to purchase equity securities do not entitle the
           holder to dividends or voting rights with respect to the underlying
           securities, nor do they represent any rights in the assets of the
           issuer of those securities.
   
           In addition to options on securities, a Fund may also purchase and
           sell call and put options on securities indexes. A 

                                       27
<PAGE>

           stock index reflects in a single number the market value of many
           different stocks. Relative values are assigned to the stocks included
           in an index and the index fluctuates with changes in the market
           values of the stocks. The options give the holder the right to
           receive a cash settlement during the term of the option based on the
           difference between the exercise price and the value of the index. By
           writing a put or call option on a securities index, a Fund is
           obligated, in return for the premium received, to make delivery of
           this amount. A Fund may offset its position in stock index options
           prior to expiration by entering into a closing transaction on an
           exchange or it may let the option expire unexercised.

           Use of options on securities indexes entails the risk that trading in
           the options may be interrupted if trading in certain securities
           included in the index is interrupted. A Fund will not purchase these
           options unless a Fund's sub-adviser is satisfied with the
           development, depth and liquidity of the market and believes the
           options can be closed out.

           Price movements in a Fund's securities may not correlate precisely
           with movements in the level of an index and, therefore, the use of
           options on indexes cannot serve as a complete hedge and will depend,
           in part, on the ability of its sub-adviser to predict correctly
           movements in the direction of the stock market generally or of a
           particular industry. Because options on securities indexes require
           settlement in cash, a Fund's sub-adviser may be forced to liquidate
           Fund securities to meet settlement obligations.

           The amount of risk a Fund assumes when it buys an option on a futures
           contract is the premium paid for the option plus related transaction
           costs. In addition to the correlation risks discussed above, the
           purchase of an option also entails the risk that changes in the value
           of the underlying futures contract will not be fully reflected in the
           value of the options bought.

      D.   OPTIONS ON FOREIGN CURRENCIES. Each of the Funds, other than the
           Tax-Exempt and the Income Plus Funds, may buy and write options on
           foreign currencies in a manner similar to that in which futures
           contracts or forward contracts on foreign currencies will be
           utilized. For example, a decline in the U.S. dollar value of a
           foreign currency in which Fund securities are denominated will reduce
           the U.S. dollar value of such securities, even if their value in the
           foreign currency remains constant. In order to protect against such
           diminutions in the value of Fund securities, a Fund may buy put
           options on the foreign currency. If the value of the currency
           declines, such Fund will have the right to sell such currency for a
           fixed amount in U.S. dollars and will offset, in whole or in part,
           the adverse effect on its portfolio.

           Conversely, when a rise in the U.S. dollar value of a currency in
           which securities to be acquired are denominated is projected, thereby
           increasing the cost of such securities, a Fund may buy call options
           thereon. The purchase of such options could offset, at least
           partially, the effects of the adverse movements in exchange rates. As
           in the case of other types of options, however, the benefit to a Fund
           from purchases of foreign currency options will be reduced by the
           amount of the premium and related transaction costs. In addition, if
           currency exchange rates do not move in the direction or to the extent
           desired, a Fund could sustain losses on transactions in foreign
           currency options that would require such Fund to forego a portion or
           all of the benefits of advantageous changes in those rates. In
           addition, in the case of other types of options, the benefit to the
           Fund from purchases of foreign currency options will be reduced by
           the amount of the premium and related transaction costs.

           A Fund may also write options on foreign currencies. For example, in
           attempting to hedge against a potential decline in the U.S. dollar
           value of foreign currency denominated securities due to adverse
           fluctuations in exchange rates, a Fund could, instead of purchasing a
           put option, write a call option on the relevant currency. If the
           expected decline occurs, the option will most likely not be exercised
           and the diminution in value of Fund securities will be offset by the
           amount of the premium received.

           Similarly, instead of purchasing a call option to attempt to hedge
           against a potential increase in the U.S. dollar cost of securities to
           be acquired, a Fund could write a put option on the relevant currency
           which, if rates move in the manner projected, will expire unexercised
           and allow that Fund to hedge the increased cost up to the amount of
           premium. As in the case of other types of options, however, the
           writing of a foreign currency option will constitute only a partial
           hedge up to the amount of the premium. If exchange rates do not move
           in the expected direction, the option may be exercised and a Fund
           would be required to buy or sell the underlying currency at a loss
           which may not be offset by the amount of the premium. Through the
           writing of options on foreign currencies, a Fund also may lose 

                                       28
<PAGE>
           all or a portion of the benefits which might otherwise have been
           obtained from favorable movements in exchange rates.

           A Fund may write covered call options on foreign currencies. A call
           option written on a foreign currency by a Fund is "covered" if that
           Fund owns the underlying foreign currency covered by the call or has
           an absolute and immediate right to acquire that foreign currency
           without additional cash consideration (or for additional cash
           consideration that is segregated by its custodian) upon conversion or
           exchange of other foreign currency held in its Fund. A call option is
           also covered if: (i) the Fund holds a call at the same exercise price
           for the same exercise period and on the same currency as the call
           written; or (ii) at the time the call is written, an amount of cash,
           U.S. government securities or other liquid assets equal to the
           fluctuating market value of the optioned currency is segregated with
           the custodian.

           A Fund may write call options on foreign currencies for cross-hedging
           purposes that would not be deemed to be covered. A call option on a
           foreign currency is for cross-hedging purposes if it is not covered
           but is designed to provide a hedge against a decline due to an
           adverse change in the exchange rate in the U.S. dollar value of a
           security which the Fund owns or has the right to acquire and which is
           denominated in the currency underlying the option. In such
           circumstances, a Fund collateralizes the option by segregating cash
           or other liquid assets in an amount not less than the value of the
           underlying foreign currency in U.S. dollars marked-to-market daily.

      E.   FORWARD CONTRACTS. A forward contract is an agreement between two
           parties in which one party is obligated to deliver a stated amount of
           a stated asset at a specified time in the future, and the other party
           is obligated to pay a specified invoice amount for the assets at the
           time of delivery. A Fund may enter into forward contracts to purchase
           and sell government securities, foreign currencies or other financial
           instruments. Forward contracts generally are traded in an interbank
           market conducted directly between traders (usually large commercial
           banks) and their customers. Unlike futures contracts, which are
           standardized contracts, forward contracts can be specifically drawn
           to meet the needs of the parties that enter into them. The parties to
           a forward contract may agree to offset or terminate the contract
           before its maturity, or may hold the contract to maturity and
           complete the contemplated exchange.

           The following discussion summarizes a Fund's principal uses of
           forward foreign currency exchange contracts ("forward currency
           contracts"):

           A Fund may enter into forward currency contracts with stated contract
           values of up to the value of that Fund's assets. A forward currency
           contract is an obligation to buy or sell an amount of a specified
           currency for an agreed price (which may be in U.S. dollars or another
           currency). A Fund will exchange foreign currencies for U.S. dollars
           and for other foreign currencies in the normal course of business.

           They may buy and sell currencies through forward currency contracts
           in order to fix a price for securities it has agreed to buy or sell
           ("transaction hedge"). A Fund also may hedge some or all of its
           investments denominated in foreign currency, or exposed to foreign
           currency fluctuations against a decline in the value of that currency
           relative to the U.S. dollar. This is accomplished by entering into
           forward currency contracts to sell an amount of that currency (or a
           proxy currency whose performance is expected to replicate or exceed
           the performance of that currency relative to the U.S. dollar)
           approximating the value of some or all of its Fund securities
           denominated in that currency ("position hedge"), or by participating
           in options or futures contracts with respect to the currency.

           A Fund also may enter into a forward currency contract with respect
           to a currency where such Fund is considering the purchase or sale of
           investments denominated in that currency but has not yet selected the
           specific investments ("anticipatory hedge"). In any of these
           circumstances a Fund may, alternatively, enter into a forward
           currency contract to purchase or sell one foreign currency for a
           second currency that is expected to perform more favorably relative
           to the U.S. dollar if the Fund's sub-adviser believes there is a
           reasonable degree of correlation between movements in the two
           currencies ("cross-hedge").

           These types of hedging seek to minimize the effect of currency
           appreciation as well as depreciation, but do not eliminate
           fluctuations in the underlying U.S. dollar equivalent value of the
           proceeds of, or rates of return on, a Fund's foreign currency
           denominated Fund securities. The matching of the increase in value of
           a forward contract and the 

                                       29
<PAGE>

           decline in the U.S. dollar equivalent value of the foreign currency
           denominated asset that is the subject of the hedge generally will not
           be precise. Shifting a Fund's currency exposure from one foreign
           currency to another removes that Fund's opportunity to profit from
           increases in the value of the original currency and involves a risk
           of increased losses to such Fund if the Fund's sub-adviser's
           projection of future exchange rates is inaccurate. Proxy hedges and
           cross-hedges may result in losses if the currency used to hedge does
           not perform similarly to the currency in which hedged securities are
           denominated. Unforeseen changes in currency prices may result in
           poorer overall performance for a Fund than if it had not entered into
           such contracts.

           A Fund will cover outstanding forward currency contracts by
           maintaining liquid Fund securities denominated in the currency
           underlying the forward contract or the currency being hedged. To the
           extent that a Fund is not able to cover its forward currency
           positions with underlying Fund securities, its custodian will
           segregate cash or other liquid assets having a value equal to the
           aggregate amount of such Fund's commitments under forward contracts
           entered into with respect to position hedges, cross-hedges and
           anticipatory hedges. If the value of the securities used to cover a
           position or the value of segregated assets declines, the Fund will
           find alternative cover or segregate additional cash or other liquid
           assets on a daily basis so that the value of the covered and
           segregated assets will be equal to the amount of a Fund's commitments
           with respect to such contracts.

           As an alternative to segregating assets, a Fund may buy call options
           permitting the Fund to buy the amount of foreign currency being
           hedged by a forward sale contract, or a Fund may buy put options
           permitting it to sell the amount of foreign currency subject to a
           forward buy contact.

           While forward contracts are not currently regulated by the CFTC, the
           CFTC may in the future assert authority to regulate forward
           contracts. In such event, a Fund's ability to utilize forward
           contracts may be restricted. In addition, a Fund may not always be
           able to enter into forward contracts at attractive prices and may be
           limited in its ability to use these contracts to hedge its assets.

      F.   SWAPS AND SWAP-RELATED PRODUCTS. In order to attempt to protect the
           value of its investments from interest rate or currency exchange rate
           fluctuations, each of the Funds, other than the Tax-Exempt and the
           Income Plus Funds, may enter into interest rate and currency exchange
           rate swaps, and may buy or sell interest rate and currency exchange
           rate caps and floors. A Fund's sub-adviser may enter into these
           transactions primarily to attempt to preserve a return or spread on a
           particular investment or portion of its portfolio. A Fund also may
           enter into these transactions to attempt to protect against any
           increase in the price of securities the Fund may consider buying at a
           later date.

           The Funds do not intend to use these transactions as a speculative
           investment. Interest rate swaps involve the exchange by a Fund with
           another party of their respective commitments to pay or receive
           interest, E.G., an exchange of floating rate payments for fixed rate
           payments. The exchange commitments can involve payments to be made in
           the same currency or in different currencies. The purchase of an
           interest rate cap entitles the purchaser, to the extent that a
           specified index exceeds a predetermined interest rate, to receive
           payments of interest on a contractually based principal amount from
           the party selling the interest rate cap. The purchase of an interest
           rate floor entitles the purchaser, to the extent that a specified
           index falls below a predetermined interest rate, to receive payments
           of interest on a contractually based principal amount from the party
           selling the interest rate floor.

           Each of the Funds, other than the Tax-Exempt and Income Plus Funds,
           may enter into interest rate swaps, caps and floors on either an
           asset-based or liability-based basis, depending upon whether it is
           hedging its assets or its liabilities, and will usually enter into
           interest rate swaps on a net basis, (I.E., the two payment streams
           are netted out, 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 entitlements with
           respect to each interest rate swap, will be calculated on a daily
           basis. An amount of cash or other liquid assets having an aggregate
           net asset at least equal to the accrued excess will be segregated by
           its custodian.

           If a Fund enters into an interest rate swap on other than a net
           basis, it will maintain a segregated account in the full amount
           accrued on a daily basis of its obligations with respect to the swap.
           A Fund will not enter into any interest rate swap, cap or floor
           transaction unless the unsecured senior debt or the claims-paying
           ability of the other party thereto 

                                       30
<PAGE>

           is rated in one of the three highest rating categories of at least
           one nationally recognized statistical rating organization at the time
           of entering into such transaction. A Fund's sub-adviser will monitor
           the creditworthiness of all counterparties on an ongoing basis. If
           there is a default by the other party to such a transaction, the Fund
           will have contractual remedies pursuant to the agreements related to
           the transaction.

           The swap market has grown substantially in recent years with a large
           number of banks and investment banking firms acting both as
           principals and as agents utilizing standardized swap documentation.
           The sub-advisers have determined that, as a result, the swap market
           has become relatively liquid. Caps and floors are more recent
           innovations for which standardized documentation has not yet been
           developed and, accordingly, they are less liquid than swaps. To the
           extent a Fund sells (I.E., writes) caps and floors, it will segregate
           cash or other liquid assets having an aggregate net asset value at
           least equal to the full amount, accrued on a daily basis, of its
           obligations with respect to any caps or floors.

           There is no limit on the amount of interest rate swap transactions
           that may be entered into by the Funds (except the Tax-Exempt and
           Income Plus Funds which may not participate in these transactions),
           although none of the Funds presently intends to engage in such
           transactions in excess of 5% of its total assets. These transactions
           may in some instances involve the delivery of securities or other
           underlying assets by a Fund or its counterparty to collateralize
           obligations under the swap.

           Under the documentation currently used in those markets, the risk of
           loss with respect to interest rate swaps is limited to the net amount
           of the interest payments that a Fund is contractually obligated to
           make. If the other party to an interest rate swap that is not
           collateralized defaults, a Fund would risk the loss of the net amount
           of the payments that it contractually is entitled to receive. A Fund
           may buy and sell (I.E., write) caps and floors without limitation,
           subject to the segregation requirement described above.

           In addition to the instruments, strategies and risks described in
           this Statement of Additional Information and in the Prospectus, there
           may be additional opportunities in connection with options, futures
           contracts, forward currency contracts and other hedging techniques
           that become available as a Fund's sub-adviser develops new
           techniques, as regulatory authorities broaden the range of permitted
           transactions, and as new instruments are developed. The Funds'
           sub-advisers may use these opportunities to the extent they are
           consistent with each Fund's investment objective and as are permitted
           by a Fund's investment limitations and applicable regulatory
           requirements.

      G.   EURODOLLAR INSTRUMENTS. The Funds may each make investments in
           Eurodollar instruments. Eurodollar instruments are U.S.
           dollar-denominated futures contracts, or options thereon, which are
           linked to the London Interbank Offered Rate (the "LIBOR"), although
           foreign currency-denominated instruments are available from time to
           time. Eurodollar futures contracts enable purchasers to obtain a
           fixed rate for the lending of funds, and sellers to obtain a fixed
           rate for borrowings. A Fund might use Eurodollar futures contracts
           and options thereon to hedge against changes in LIBOR, which may be
           linked to many interest rate swaps and fixed income instruments.

      H.   SPECIAL INVESTMENT CONSIDERATIONS AND RISKS. The successful use of
           the investment practices described above with respect to futures
           contracts, options on futures contracts, forward contracts, options
           on securities, options on foreign currencies and swaps and
           swap-related products draws upon skills and experience which are
           different from those needed to select the other instruments in which
           a Fund may invest. Should interest or exchange rates, or the prices
           of securities or financial indices move in an unexpected manner, a
           Fund may not achieve the desired benefits of the foregoing
           instruments or may realize losses and thus be in a worse position
           than if such strategies had not been used. Unlike many
           exchange-traded futures contracts and options on futures contracts,
           there are no daily price fluctuation limits with respect to options
           on currencies, forward contracts and other negotiated or
           over-the-counter instruments, and adverse market movements could
           therefore continue to an unlimited extent over a period of time. In
           addition, the correlation between movements in the price of the
           securities and currencies hedged or used for cover will not be
           perfect and could produce unanticipated losses.

           A Fund's ability to dispose of its positions in the foregoing
           instruments will depend on the availability of liquid markets in the
           instruments. Markets in a number of the instruments are relatively
           new and still developing, and it is impossible 

                                       31
<PAGE>

           to predict the amount of trading interest that may exist in those
           instruments in the future.

           Particular risks exist with respect to the use of each of the
           foregoing instruments and could result in such adverse consequences
           to a Fund as: the possible loss of the entire premium paid for an
           option bought by a Fund; the inability of the Fund, as the writer of
           a covered call option, to benefit from the appreciation of the
           underlying securities above the exercise price of the option; and the
           possible need to defer closing out positions in certain instruments
           to avoid adverse tax consequences. As a result, no assurance can be
           given that a Fund will be able to use those instruments effectively
           for their intended purposes.

           In connection with certain of its hedging transactions, a Fund must
           segregate assets with the Fund's custodian bank to ensure that such
           Fund will be able to meet its obligations pursuant to these
           instruments. Segregated assets generally may be not be disposed of
           for so long as a Fund maintains the positions giving rise to the
           segregation requirement. Segregation of a large percentage of a
           Fund's assets could impede implementation of that Fund's investment
           policies or its ability to meet redemption requests or other current
           obligations.

      I.   ADDITIONAL RISKS OF OPTIONS ON FOREIGN CURRENCIES, FORWARD CONTRACTS
           AND FOREIGN INSTRUMENTS. Unlike transactions entered into by a Fund
           in futures contracts, options on foreign currencies and forward
           contracts are not traded on contract markets regulated by the CFTC or
           (with the exception of certain foreign currency options) by the SEC.
           To the contrary, such instruments are traded through financial
           institutions acting as market-makers, although foreign currency
           options are also traded on certain national securities exchanges,
           such as the Philadelphia Stock Exchange and the Chicago Board Options
           Exchange, subject to SEC regulation.
    
           Options on currencies may be traded over-the-counter. In an
           over-the-counter trading environment, many of the protections
           afforded to exchange participants will not be available. For example,
           there are no daily price fluctuation limits, and adverse market
           movements could therefore continue to an unlimited extent over a
           period of time. Although the buyer of an option cannot lose more than
           the amount of the premium plus related transaction costs, this entire
           amount could be lost. Moreover, an option writer and a buyer or
           seller of futures or forward contracts could lose amounts
           substantially in excess of any premium received or initial margin or
           collateral posted due to the potential additional margin and
           collateral requirements associated with such positions.
   
           Options on foreign currencies traded on national securities exchanges
           are within the jurisdiction of the SEC, as are other securities
           traded on such exchanges. As a result, many of the protections
           provided to traders on organized exchanges will be available with
           respect to such transactions. In particular, all foreign currency
           option positions entered into on a national securities exchange are
           cleared and guaranteed by the OCC, thereby reducing the risk of
           counterparty default. Further, a liquid secondary market in options
           traded on a national securities exchange may be more readily
           available than in the over-the-counter market, potentially permitting
           a Fund to liquidate open positions at a profit prior to exercise or
           expiration, or to limit losses in the event of adverse market
           movements.
    
           The purchase and sale of exchange-traded foreign currency options,
           however, is subject to the risks of the availability of a liquid
           secondary market described above, as well as the risks regarding
           adverse market movements, margining of options written, the nature of
           the foreign currency market, possible intervention by governmental
           authorities and the effects of other political and economic events.

            In addition, exchange-traded options on foreign currencies involve
           certain risks not presented by the over-the-counter market. For
           example, exercise and settlement of such options must be made
           exclusively through the OCC, which has established banking
           relationships in applicable foreign countries for this purpose. As a
           result, the OCC may, if it determines that foreign government
           restrictions or taxes would prevent the orderly settlement of foreign
           currency option exercises, or would result in undue burdens on the
           OCC or its clearing member, impose special procedures on exercise and
           settlement. These include such things as technical changes in the
           mechanics of delivery of currency, the fixing of dollar settlement
           prices or prohibitions on exercise.

           In addition, options on U.S. government securities, futures
           contracts, options on futures contracts, forward contracts and
           options on foreign currencies may be traded on foreign exchanges and
           over-the-counter in foreign countries. Such

                                       32
<PAGE>

           transactions are subject to the risk of governmental actions
           affecting trading in or the prices of foreign currencies or
           securities. The value of such positions also could be adversely
           affected by: (i) other complex foreign political and economic
           factors; (ii) less availability than that available in the United
           States of data on which to make trading decisions; (iii) delays in a
           Fund's ability to act upon economic events occurring in foreign
           markets during nonbusiness hours in the United States; (iv) the
           imposition of different exercise and settlement terms and procedures
           and margin requirements than in the United States; and (v) low
           trading volume.

OTHER INVESTMENT COMPANIES.
   
      Some of the Funds may invest in securities issued by other investment
companies, within limits described in the investment restrictions for the
relevant Fund. A Fund may indirectly bear a portion of any investment advisory
fees and expenses paid by Funds in which it invests, in addition to the advisory
fees and expenses paid by the Fund.

      The International Equity Fund may not purchase securities of other
investment companies, other than a security acquired in connection with a
merger, consolidation, acquisition, reorganization or offer of exchange and
except as otherwise permitted under the 1940 Act. An investment by the
International Equity Fund in GEI Short-Term Investment Fund, is not considered
an investment in another investment company for purposes of this resctriction.
The GEI Short-Term Investment Fund is an investment Fund advised by GEIM,
created specifically to serve as a vehicle for the collective investment of cash
balances of the Fund and other accounts advised by GEIM or its affiliate,
General Electric Investment Corporation.
    

ZERO COUPON, PAY-IN-KIND AND STEP COUPON SECURITIES.

   
      Subject to each Fund's investment restrictions, a Fund may invest in zero
coupon, pay-in-kind and step-coupon securities. Zero-coupon bonds are issued and
traded at a discount from their face value. They do not entitle the holder to
any periodic payment of interest prior to maturity. Step coupon bonds trade at a
discount from their face value and pay coupon interest. The coupon rate is low
for an initial period and then increases to a higher coupon rate thereafter. The
discount from the face amount or par value depends on the time remaining until
cash payments begin, prevailing interest rates, liquidity of the security and
the perceived credit quality of the issuer. Pay-in-kind bonds give the issuer an
option to pay cash at a coupon payment date or give the holder of the security a
similar bond with the same coupon rate and a face value equal to the amount of
the coupon payment that would have been made. The Flexible Income Fund may also
invest in "strips," which are debt securities that are stripped of their
interest after the securities are issued, but otherwise are comparable to zero
coupon bonds.

      Current federal income tax law requires holders of zero-coupon securities
and step-coupon securities to report the portion of the original issue discount
on such securities that accrues that year as interest income, even though the
holders receive no cash payments of interest during the year. In order to
qualify as a "regulated investment company" under the Internal Revenue Code of
1986 ("Code"), a Fund must distribute its investment company taxable income,
including the original issue discount accrued on zero-coupon or step-coupon
bonds. Because it will not receive cash payments on a current basis in respect
of accrued original-issue discount on zero-coupon bonds or step-coupon bonds
during the period before interest payments begin, in some years a Fund may have
to distribute cash obtained from other sources in order to satisfy the
distribution requirements under the Code. A Fund might obtain such cash from
selling other portfolio holdings. These actions may reduce the assets to which
Fund expenses could be allocated and may reduce the rate of return for such
Fund. In some circumstances, such sales might be necessary in order to satisfy
cash distribution requirements even though investment considerations might
otherwise make it undesirable for a Fund to sell the securities at the time.
    

      Generally, the market prices of zero-coupon bonds and strip securities are
more volatile than the prices of securities that pay interest periodically in
cash and they are likely to respond to changes in interest rates to a greater
degree than other types of debt securities having similar maturities and credit
quality.

INCOME-PRODUCING SECURITIES.

      The Flexible Income Fund focuses its investments in income-producing
securities.
   
      The Flexible Income Fund will purchase defaulted securities only when the
sub-adviser believes, based upon analysis of the financial condition, results of
operations and economic outlook of an issuer, that there is potential for
resumption of income payments and that the securities offer an unusual
opportunity for capital appreciation. Notwithstanding the sub-adviser's belief
as to the resumption of income payments, however, the purchase of any security
on which payment of interest or dividends is suspended involves a high degree of
risk. Such risk includes, among other things, the following:
    
      A.   FINANCIAL AND MARKET RISKS. Investments in securities that are in
           default involve a high degree of financial and market risks that can
           result in substantial, or at times even total, losses. Issuers of
           defaulted securities may have substantial capital needs and may
           become involved in bankruptcy or reorganization proceedings. Among
           the problems involved in investments in such issuers is the fact that
           it may be difficult to obtain information about the condition of such
           issuers. The market prices of such securities also are subject to
           abrupt and erratic movements and above average price volatility, and
           the spread between the bid and asked prices of such securities may be
           greater than normally expected.
   
      B.   DISPOSITION OF PORTFOLIO SECURITIES. Although the Flexible Income
           Fund generally intends to purchase securities for which its
           sub-adviser expects an active market to be maintained, defaulted
           securities may be less actively traded than other securities making
           it more difficult to dispose of substantial holdings of such
           securities at prevailing market prices. The Flexible Income Fund will
           limit its holdings of any such securities to amounts that the
           sub-adviser believes could be readily sold, and its holdings of such
           securities would, in any event, be limited so as not to limit the
           Flexible Income Fund's ability to readily dispose of its securities
           to meet redemptions.

      C.   OTHER. Defaulted securities require active monitoring and may, at
           times, require participation in bankruptcy or receivership
           proceedings on behalf of the Flexible Income Fund.

      Other types of income producing securities that the Funds may purchase
include, but are not limited to, the following:
    
      VARIABLE AND FLOATING RATE OBLIGATIONS. These types of securities are
      relatively long-term instruments that often carry demand features
      permitting the holder to demand payment of principal at any time or at
      specified intervals prior to maturity.
   
      STANDBY COMMITMENTS. These instruments, which are similar to a put, give a
      Fund the option to obligate a broker, dealer or bank to repurchase a
      security held by a Fund at a specified price.
    

      TENDER OPTION BONDS. Tender option bonds are relatively long-term bonds
      that are coupled with the agreement of a third party (such as a broker,
      dealer or bank) to grant the holders of such securities the option to
      tender the securities to the institution at periodic intervals.

      INVERSE FLOATERS. Inverse floaters are instruments whose interest bears an
      inverse relationship to the interest rate on another security. The Funds
      will not invest more than 5% of their respective assets in inverse
      floaters.
   
      The Funds will purchase instruments with demand features, standby
commitments and tender option bonds primarily for the purpose of increasing the
liquidity of their portfolios.

LENDING OF FUND SECURITIES.
   
      Subject to any applicable investment restriction relating to lending, each
of the Funds, other than the Tax-Exempt, Mid-Cap Summit and the Income Plus
Funds may lend securities from its portfolio. Under applicable regulatory
requirements (which are subject to change), the following conditions apply to
securities loans: a) the loan must be continuously secured by liquid assets
maintained on a current basis in an amount at least equal to the market value of
the securities loaned; b) a Fund must receive any dividends or interest paid by
the issuer on such securities; c) a Fund must have the right to call the loan
and obtain the securities loaned at any time upon notice of not more than five
business days, including the right to call the loan to permit voting of the
securities; and d) a Fund must receive either interest from the investment of
collateral or a fixed fee from the borrower. Securities loaned by a Fund remain
subject to fluctuations in market value. A Fund may pay reasonable finders,
custodian and administrative fees in connection with a loan. Securities lending,
as with other extensions of credit, involves the risk that the borrower may
default. Although securities loans will be fully collateralized at all times, a
Fund may experience delays in, or be prevented from, recovering the collateral.
During a period that a Fund seeks to enforce its rights against the borrower,
the collateral and the securities loaned remain subject to fluctuations in
market value. A Fund may also incur expenses in enforcing its rights. If a Fund
has sold the loaned security, it may not be able to settle the sale of the
security and may incur potential liability to the buyer of the security on loan
for its costs to cover the purchase. The Funds will not lend securities to any
advisers or sub-advisers to the Funds or their affiliates. By lending its
securities, a Fund can increase its income by continuing to receive interest or
dividends on the loaned securities as well as by either investing the cash
collateral in short-term securities or by earning income in the form of interest
paid by the borrower when U.S. government securities are used as collateral.
    

JOINT TRADING ACCOUNTS.
   
      The Growth, Global, Flexible Income, Balanced and Capital Appreciation
Funds and other clients of Janus Capital and its affiliates may place assets in
joint trading accounts for the purpose of making short-term investments in money
market instruments. The Board of Trustees of the Fund must approve the
participation of each of these Funds in these joint trading accounts and
procedures pursuant to which the joint accounts will operate. The joint trading
accounts are to be operated pursuant to an exemptive order issued to Janus
Capital and certain of its affiliates by the SEC. All joint account
participants, including these Funds, will bear the expenses of the joint trading
accounts in proportion to their investments. Financial difficulties of other
participants in the joint accounts could cause delays or other difficulties for
the Funds in withdrawing their assets from joint trading accounts.
    

ILLIQUID SECURITIES.

   
      Subject to each Fund's investment restrictions, a Fund may invest its
assets in illiquid securities (I.E., securities that are not readily
marketable). The Board of Trustees has authorized the sub-advisers to make
liquidity determinations with respect to its securities, including Rule 144A
securities, commercial paper and municipal lease obligations in accordance with
the guidelines established by the Board of Trustees. Under the guidelines, the
sub-adviser will consider the following factors in determining whether a Rule
144A security or a municipal lease obligation is liquid: 1) the frequency of
trades and quoted prices for the security; 2) the number of dealers willing to
purchase or sell the security and the number of other potential purchasers; 3)
the willingness of dealers to undertake to make a market in the security; and 4)
the nature of the marketplace trades, including the time needed to dispose of
the security, the method of soliciting offers and the mechanics of the transfer.
With respect to municipal lease obligations, the sub-adviser of the Tax-Exempt
and Flexible Income Funds will also consider factors unique to municipal lease
obligations including the general creditworthiness of the municipality, the
importance of the property covered by the lease obligation and the likelihood
that the marketability of the obligation will be maintained throughout the time
the obligation is held by the Fund. The sale of illiquid securities often
requires more time and results in higher brokerage charges or dealer discounts
and other selling expenses than does the sale of securities eligible for trading
on national securities exchanges or in the over-the-counter markets. A Fund may
be restricted in its ability to sell such securities at a time when the
sub-adviser deems it advisable to do so. In addition, in order to meet
redemption requests, a Fund may have to sell other assets, rather than such
illiquid securities, at a time which is not advantageous.
    

                                       35

<PAGE>


REPURCHASE AND REVERSE REPURCHASE AGREEMENTS.
   
      Subject to each Fund's investment restrictions, a Fund may enter into
repurchase and reverse repurchase agreements. In a repurchase agreement, a Fund
purchases a security and simultaneously commits to resell that security to the
seller at an agreed upon price on an agreed upon date within a number of days
(usually not more than seven) from the date of purchase. The resale price
reflects the purchase price plus an agreed upon incremental amount which is
unrelated to the coupon rate or maturity of the purchased security. A repurchase
agreement involves the obligation of the seller to pay the agreed upon price,
which obligation is in effect secured by the value (at least equal to the amount
of the agreed upon resale price and marked-to-market daily) of the underlying
security or collateral). A Fund may engage in a repurchase agreement with
respect to any security in which it is authorized to invest. While it does not
presently appear possible to eliminate all risks from these transactions
(particularly the possibility of a decline in the market value of the underlying
securities, as well as delays and costs to a Fund in connection with bankruptcy
proceedings), it is the policy of each Fund to limit repurchase agreements to
those parties whose creditworthiness has been reviewed and found satisfactory by
the sub-adviser for that Fund and approved by the Board of Trustees of the Fund.
In addition, the Funds currently intend to invest primarily in repurchase
agreements collateralized by cash, U.S. government securities, or money market
instruments whose value equals at least 100% of the repurchase price,
marked-to-market daily.

      In a reverse repurchase agreement, a Fund sells a portfolio instrument to
another party, such as a bank or broker-dealer, in return for cash and agrees to
repurchase the instrument at a particular price and time. While a reverse
repurchase agreement is outstanding, a Fund will segregate with its custodian
cash and appropriate liquid assets with the Funds' custodian to cover its
obligation under the agreement. The Funds will enter into reverse repurchase
agreements only with parties the investment sub-adviser for each Fund deems
creditworthy and that have been reviewed by the Board of Trustees of the Funds.
    

PASS-THROUGH SECURITIES.
   
      Each of the Funds may, in varying degrees, invest in various types of
pass-through securities, such as mortgage-backed securities, asset-backed
securities and participation interests. A pass-through security is a share or
certificate of interest in a pool of debt obligations that have been repackaged
by an intermediary, such as a bank or broker-dealer. The purchaser receives an
undivided interest in the underlying pool of securities. The issuers of the
underlying securities make interest and principal payments to the intermediary
which are passed through to purchasers, such as the Funds.

      The most common type of pass-through securities are mortgage-backed
securities. Government National Mortgage Association ("GNMA") Certificates are
mortgage-backed securities that evidence an undivided interest in a pool of
mortgage loans. GNMA Certificates differ from traditional bonds in that
principal is paid back monthly by the borrowers over the term of the loan rather
than returned in a lump sum at maturity. A Fund will generally purchase
"modified pass-through" GNMA Certificates, which entitle the holder to receive a
share of all interest and principal payments paid and owned on the mortgage
pool, net of fees paid to the "issuer" and GNMA, regardless of whether or not
the mortgagor actually makes the payment. GNMA Certificates are backed as to the
timely payment of principal and interest by the full faith and credit of the
U.S. government.
    

      The Federal Home Loan Mortgage Corporation ("FHLMC") issues two types of
mortgage pass-through securities: mortgage participation certificates ("PCs")
and guaranteed mortgage certificates ("GMCs"). PCs resemble GNMA Certificates in
that each PC represents a pro rata share of all interest and principal payments
made and owned on the underlying pool. FHLMC guarantees timely payments of
interest on PCs and the full return of principal. GMCs also represent a pro rata
interest in a pool of mortgages. However, these instruments pay interest
semi-annually and return principal once a year in guaranteed minimum payments.
This type of security is guaranteed by FHLMC as to timely payment of principal
and interest, but is not backed by the full faith and credit of the U.S.
government.

      The Federal National Mortgage Association ("FNMA") issues guaranteed
mortgage pass-through certificates ("FNMA Certificates"). FNMA Certificates
resemble GNMA Certificates in that each FNMA Certificate represents a pro rata
share of all interest and principal payments made and owned on the underlying
pool. This type of security is guaranteed by FNMA as to timely payment of
principal and interest, but it is not backed by the full faith and credit of the
U.S. government.

   
      Each of the mortgage-backed securities described above is characterized by
monthly payments to the holder, reflecting the monthly payments made by the
borrowers who received the underlying mortgage loans. The payments to the
security holders (such as a Fund), like the payments on the underlying loans,
represent both principal and interest. Although the underlying 

                                       36

<PAGE>


mortgage loans are for specified periods of time, such as 20 or 30 years, the
borrowers can, and typically do, pay them off sooner. Thus, the security holders
frequently receive prepayments of principal in addition to the principal that is
part of the regular monthly payments. A borrower is more likely to prepay a
mortgage that bears a relatively high rate of interest. This means that in times
of declining interest rates, some of a Fund's higher yielding mortgage-backed
securities may be converted to cash. That Fund will then be forced to accept
lower interest rates when that cash is used to purchase additional securities in
the mortgage-backed securities sector or in other investment sectors. Mortgage
and asset-backed securities may have periodic income payments or may pay
interest at maturity (as is the case with Treasury bills or zero-coupon bonds).
    

      Asset-backed securities represent interests in pools of consumer loans and
are backed by paper or accounts receivables originated by banks, credit card
companies or other providers of credit. Generally, the originating bank or
credit provider is neither the obligor or guarantor of the security and interest
and principal payments ultimately depend upon payment of the underlying loans by
individuals. Tax-exempt asset-backed securities include units of beneficial
interests in pools of purchase contracts, financing leases, and sales agreements
that may be created when a municipality enters into an installment purchase
contract or lease with a vendor. Such securities may be secured by the assets
purchased or leased by the municipality; however, if the municipality stops
making payments, there generally will be no recourse against the vendor. The
market for tax-exempt asset-backed securities is still relatively new. These
obligations are likely to involve unscheduled prepayments of principal.

HIGH-YIELD/HIGH-RISK BONDS.

      High-yield/high-risk, below investment grade securities (commonly known as
"junk bonds") involve significant credit and liquidity concerns and fluctuating
yields, and are not suitable for short-term investing. Higher yields are
ordinarily available on fixed-income securities which are unrated or are rated
in the lower rating categories of recognized rating services such as Moody's and
Standard & Poor's.
   
      Lower rated bonds also involve the risk that the issuer will not make
interest or principal payments when due. In the event of an unanticipated
default, a Fund owning such bonds would experience a reduction in its income,
and could expect a decline in the market value of the securities so affected.
Such Funds, furthermore, may incur additional costs in seeking the recovery of
the defaulted securities. More careful analysis of the financial condition of
each issuer of lower rated securities is therefore necessary. During an economic
downturn or substantial period of rising interest rates, highly leveraged
issuers may experience financial stress which would adversely affect their
ability to service their principal and interest payments obligations, to meet
projected business goals and to obtain additional financing.
    

      The market prices of lower grade securities are generally less sensitive
to interest rate changes than higher rated investments, but more sensitive to
adverse economic or political changes or individual developments specific to the
issuer. Periods of economic or political uncertainty and change can be expected
to result in volatility of prices of these securities. Since the last major
economic recession, there has been a substantial increase in the use of
high-yield debt securities to fund highly leveraged corporate acquisitions and
restructurings, so past experience with high-yield securities in a prolonged
economic downturn may not provide an accurate indication of future performance
during such periods. Lower rated securities also may have less liquid markets
than higher rated securities, and their liquidity as well as their value may be
more severely affected by adverse economic conditions. Adverse publicity and
investor perceptions as well as new or proposed laws may also have a greater
negative impact on the market for lower rated bonds.

   
      Unrated securities are not necessarily of lower quality than rated
securities, but the markets for lower rated and nonrated securities are more
limited than those in which higher rated securities are traded. In addition, an
economic downturn or increase in interest rates is likely to have a greater
negative effect on: (i) the market for lower rated and nonrated securities; (ii)
the value of high yield debt securities held by a Fund; (iii) the new asset
value of a Fund holding such securities; and (iv) the ability of the bonds'
issuers to repay principal and interest, meet projected business goals and
obtain additional financing than on higher rated securities.

WARRANTS AND RIGHTS.
   
      Each of the Funds, other than the Tax-Exempt Fund, may invest in warrants
and rights. A warrant is a type of security that entitles the holder to buy a
proportionate amount of common stock at a specified price, usually higher than
the market price at the time of issuance, for a period of years or to
perpetuity. In contrast, rights, which also represent the right to buy common
shares, normally have a subscription price lower than the current market value
of the common stock and a life of two to four weeks.
    

U.S. GOVERNMENT SECURITIES.

      Examples of the types of U.S. government securities that the Funds may
hold include, in addition to those described in the Prospectus and direct
obligations of the U.S. Treasury, the obligations of the Federal Housing
Administration, Farmers Home Administration, Small Business Administration,
General Services Administration, Central Bank for Cooperatives, Federal Farm
Credit Banks, Federal Home Loan Bank, Federal Intermediate Credit Banks, Federal
Land Banks and Maritime Administration. U.S. government securities may be
supported by the full faith and credit of the U.S. government (such as
securities of the Small Business Administration); by the right of the issuer to
borrow from the Treasury (such as securities of the Federal Home Loan Bank); by
the discretionary authority of the U.S. government to purchase the agency's
obligations (such as securities of the Federal National Mortgage Association);
or only by the credit of the issuing agency.

           *No information is included for the Blue Chip, Dividend Growth,
Mid-Cap Opportunities, Mid-Cap Summit or Small Cap Frontier Funds as these Funds
commenced operations on March 1, 1999.

      As stated in the Prospectus, each of the Funds generally intend to
purchase and sell securities as deemed appropriate by the Fund's sub-adviser to
further a Fund's stated investment objective, and the rate of Fund turnover is
not expected to be a limiting factor when changes are deemed to be appropriate.
Fund transactions for the Tax-Exempt Fund and Income Plus Fund are ordinarily
undertaken to achieve each Fund's investment objective in light of anticipated
movements in the level of interest rates. The investment policies of the
Tax-Exempt and the Income Plus Funds may lead to frequent changes in
investments, particularly in periods of rapidly fluctuating interest rates.
      These percentages are calculated by dividing the lesser of purchases or
sales of Fund securities during the fiscal year by the monthly average of the
value of such securities (excluding from the computation all securities,
including options, with maturities at the time of acquisition of one year or
less). For example, a Fund turnover rate of 100% would mean that all of a Fund's
securities (except those excluded from the calculation) were replaced once in a
period of one year. A high rate of Fund turnover generally involves
correspondingly greater brokerage commission expenses.

      Turnover rates may vary greatly from year to year, as well as within a
particular year, and may also be affected by cash requirements for redemptions
of a Fund's shares and by requirements, the satisfaction of which enable the
Fund to receive favorable tax treatment. Because the rate of Fund turnover is
not a limiting factor, particular holdings may be sold at any time if investment
judgment or Fund operations make a sale advisable. As a result, the annual Fund
turnover rate in future years may exceed the percentage shown above.
    
                     INVESTMENT ADVISORY AND OTHER SERVICES
   
       IDEX Mutual Funds has entered into a Management and Investment Advisory
Agreement ("Advisory Agreement") on behalf of each Fund with IDEX Management,
Inc. ("IMI"), located at 570 Carillon Parkway, St. Petersburg, Florida 33716 and
each of the Funds. IMI supervises each respective Fund's investments and
conducts its investment program.

                                       39

<PAGE>

       The Advisory Agreement provides that IMI will perform the following
services or cause them to be performed by others: (i) furnish to the Fund with
investment advice and recommendations; (ii) supervise the purchase and sale of
securities as directed by appropriate Fund officers, and (iii) be responsible
for the administration of each Fund. For services to the Capital Appreciation,
Global, Growth and Balanced Funds, IMI receives an annual fee, computed daily
and paid monthly, equal to 1.00% of the first $750 million of that Fund's
average daily net assets, 0.90% of the next $250 million of that Fund's average
daily net assets, and 0.85% of the average daily net assets of that Fund in
excess of $1 billion. For services to the Flexible Income Fund, IMI receives
0.90% of the first $100 million, 0.80% of the next $150 million and 0.70% of
assets over $250 million; for the Income Plus and Tax-Exempt Funds, IMI receives
0.60% of each Fund's average daily net assets; and for the Aggressive Growth,
International Equity, C.A.S.E., Value Equity, Strategic Total Return, Tactical
Asset Allocation, Blue Chip, Dividend Growth, Mid-Cap Opportunities, Mid-Cap
Summit and Small Cap Frontier Fund, IMI receives 0.80% of the first $500 million
in assets and 0.70% of assets over $500 million.

       The duties and responsibilities of the investment adviser are specified
in the Advisory Agreement. The Agreement was approved by the Board of Trustees
of the Funds (including a majority of trustees who are not parties to the
Agreement or interested persons, as defined by the 1940 Act, of any such party).
The Agreement is not assignable and may be terminated without penalty upon 60
days written notice at the option of either the Fund, IMI or by a vote of
shareholders of each Fund. The Advisory Agreement provides that it can be
continued from year to year so long as such continuance is specifically approved
annually (a) by the Board of Trustees of the Funds or by a majority of the
outstanding shares of the Fund and (b) by a majority vote of the Trustees who
are not parties to the Agreement or interested persons of any such party cast in
person at a meeting. Prior to March 1, 1999, InterSecurities, Inc. served as
investment adviser to the Tax-Exempt, Income Plus, International Equity,
C.A.S.E., Value Equity, Strategic Total Return, Tactical Asset Allocation and
Aggressive Growth Funds.

       The Agreement also provides that IMI shall not be liable to the Funds or
to any shareholder for any error of judgment or mistake of law or for any loss
suffered by the Fund or by any shareholder in connection with matters to which
the Agreements relates, except for a breach of fiduciary duty or a loss
resulting from willful misfeasance, bad faith, gross negligence, or reckless
disregard on the part of IMI in the performance of its duties thereunder.

       The Advisory Agreement became effective as follows: Aggressive Growth
Fund - September 30, 1994; International Equity Fund - February 1, 1997;
C.A.S.E. fund - November 15, 1995; Value Equity Fund - October 30, 1996;
Strategic Total Return Fund - September 30, 1994; Tactical Asset Allocation Fund
- - June 1, 1995; Income Plus Fund - April 22, 1992; Tax-Exempt Fund - April 22,
1991; Capital Appreciation, Global, Growth, Balanced and Flexible Income Funds -
June 25, 1998; and Blue Chip, Dividend Growth, Mid-Cap Opportunities, Mid-Cap
Summit and Small Cap Frontier Funds - March 1, 1999.

       Each Fund pays its allocable share of the fees and expenses of the Funds'
non-interested trustees, custodian and transfer agent fees, brokerage
commissions and all other expenses in connection with the execution of its
portfolio transactions, administrative, clerical, recordkeeping, bookkeeping,
legal, auditing and accounting expenses, interest and taxes, expenses of
preparing tax returns, expenses of shareholders' meetings and preparing,
printing and mailing proxy statements (unless otherwise agreed to by the Funds
or IMI, expenses of preparing and typesetting periodic reports to shareholders
(except for those reports the Fund permits to be used as sales literature), and
the costs, including filing fees, of renewing or maintaining registration of
Fund shares under federal and state law. The investment adviser will reimburse a
Fund, or waive fees, or both, whenever, in any fiscal year, the total cost to a
Fund of normal operating expenses chargeable to its income account, including
the investment advisory fee but excluding brokerage commissions, interest, taxes
and 12b-1 fees, exceeds, in the case of the Capital Appreciation, Growth,
Balanced and Flexible Income Funds, 1.50% of each Fund's average daily net
assets; in the case of the Tax-Exempt, 1.00% of average daily net assets; and
1.20% of the Fund's average daily net assets for all other Funds. The Global
Fund does not have an expense limitation.

       AUSA Holding Company ("AUSA") owns 100% of the outstanding stock of IMI.
AUSA also owns 100% of the outstanding shares of the Fund's distributor and
transfer agent. AUSA is wholly-owned by AEGON USA, Inc., a financial services
holding company located at 4333 Edgewood Road, N.E., Cedar Rapids, Iowa 52499.
AEGON USA, Inc. is a wholly-owned indirect subsidiary of AEGON nv, a Netherlands
corporation and publicly traded international insurance group.

       Each of the sub-advisers also serves as investment adviser or sub-adviser
to other funds and/or private accounts which may have investment objectives
identical or similar to that of the Funds. Securities frequently meet the
investment objectives of one or all of these Funds, the other funds and the
private accounts. In such cases, a sub-adviser's decision to recommend a
purchase to one fund or account rather than another is based on a number of
factors. The determining factors in most cases are the amounts available for
investment by each Fund or account, the amount of securities of the issuer then
outstanding, the value of those securities and the market for them. Another
factor considered in the investment recommendations is other investments which
each fund or account presently has in a particular industry.

       It is possible that at times identical securities will be held by more
than one Fund or account. However, positions in the same issue may vary and the
length of time that any Fund or account may choose to hold its investment in the
same issue may likewise vary. To the extent that more than one of the Funds or
private accounts served by a sub-adviser seeks to acquire or sell 

                                       43

the same security at about the same time, either the price obtained by the Funds
or the amount of securities that may be purchased or sold by a Fund at one time
may be adversely affected. On the other hand, if the same securities are bought
or sold at the same time by more than one Fund or account, the resulting
participation in volume transactions could produce better executions for the
Funds. In the event more than one Fund or account purchases or sells the same
security on a given date, the purchase and sale transactions are allocated among
the Fund(s), the other Funds and the private accounts in a manner believed by
the sub-advisers to be equitable to each.

                         FUND TRANSACTIONS AND BROKERAGE
   
       Decisions as to the assignment of Fund business for each of the Funds and
negotiation of commission rates are made by a Fund's sub-adviser, whose policy
is to obtain the "best execution" (prompt and reliable execution at the most
favorable security price) of all Fund transactions. The Advisory Agreement and
Investment Counsel Agreement for each Fund specifically provide that in placing
portfolio transactions for a Fund, the Fund's sub-adviser may agree to pay
brokerage commissions for effecting a securities transaction in an amount higher
than another broker or dealer would have charged for effecting that transaction
as authorized, under certain circumstances, by the Securities Exchange Act of
1934.

       In selecting brokers and dealers and in negotiating commissions, a Fund's
sub-adviser considers a number of factors, including but not limited to:
    
     /bullet/  The sub-adviser's knowledge of currently available negotiated
               commission rates or prices of securities and other current
               transaction costs;
     /bullet/  The nature of the security being traded;
     /bullet/  The size and type of the transaction;
     /bullet/  The nature and character of the markets for the security to be
               purchased or sold;
     /bullet/  The desired timing of the trade;
     /bullet/  The activity existing and expected in the market for the
               particular security;
     /bullet/  The quality of the execution, clearance and settlement services;
     /bullet/  Financial stability;
     /bullet/  The existence of actual or apparent operational problems of any
               broker or dealer; and
     /bullet/  Research products and services provided.

    In recognition of the value of the foregoing factors, the sub-adviser may
place portfolio transactions with a broker with whom it has negotiated a
commission that is in excess of the commission another broker would have charged
for effecting that transaction. This is done if the sub-adviser determines in
good faith that such amount of commission was reasonable in relation to the
value of the brokerage and research provided by such broker viewed in terms of
either that particular transaction or of the overall responsibilities of the
sub-adviser. Research provided may include:

     /bullet/  Furnishing advice, either directly or through publications or
               writings, as to the value of securities, the advisability of
               purchasing or selling specific securities and the availability of
               securities or purchasers or sellers of securities;

                                       46
<PAGE>

     /bullet/  Furnishing seminars, information, analyses and reports concerning
               issuers, industries, securities, trading markets and methods,
               legislative developments, changes in accounting practices,
               economic factors and trends and portfolio strategy;

     /bullet/  Access to research analysts, corporate management personnel,
               industry experts, economists and government officials; and

     /bullet/  Comparative performance evaluation and technical measurement
               services and quotation services, and other services (such as
               third party publications, reports and analyses, and computer and
               electronic access, equipment, software, information and
               accessories that deliver process or otherwise utilize
               information, including the research described above) that assist
               the sub-adviser in carrying out its responsibilities.
   
       Most of the brokers and dealers used by the Fund's sub-advisers provide
research and other services described above.

       A sub-adviser may use research products and services in servicing other
accounts in addition to the Funds. If a sub-adviser determines that any research
product or service has a mixed use, such that it also serves functions that do
not assist in the investment decision-making process, a sub-adviser may allocate
the costs of such service or product accordingly. The portion of the product or
service that a sub-adviser determines will assist it in the investment
decision-making process may be paid for in brokerage commission dollars. Such
allocation may be a conflict of interest for a sub-adviser.

       When a Fund purchases or sells a security in the over-the-counter market,
the transaction takes place directly with a principal market-maker without the
use of a broker, except in those circumstances where better prices and
executions will be achieved through the use of a broker.

       A sub-adviser may also consider the sale or recommendation of a Fund's
shares by a broker or dealer to its customers as a factor in the selection of
brokers or dealers to execute portfolio transactions. In placing portfolio
business with brokers or dealers, a sub-adviser will seek the best execution of
each transaction, and all such brokerage placement must be consistent with the
Rules of Fair Practice of the National Association of Securities Dealers, Inc.

     A sub-adviser may place transactions for the purchase or sale of portfolio
securities with affiliates of IMI, ISI or the sub-adviser, including DST
Securities, Inc., or Fred Alger & Company, Incorporated. It is anticipated that
Fred Alger & Company, Incorporated, an affiliate of Alger Management, will serve
as the Aggressive Growth Fund's broker in effecting substantially all of the
Aggressive Growth Fund's transactions on securities exchanges and will retain
commissions in accordance with certain regulations of the Securities and
Exchange Commission ("SEC"). A sub-adviser may place transactions if it
reasonably believes that the quality of the transaction and the associated
commission are fair and reasonable, and if overall the associated transaction
costs, net of any credits described above under "Custodian, Transfer Agent and
Other Affiliates," are lower than those that would otherwise be incurred. Under
rules adopted by the SEC, the Funds' Board of Trustees will conduct periodic
compliance reviews of such brokerage allocations and review certain procedures
adopted by the Board of Trustees to ensure compliance with these rules and to
determine their continued appropriateness. For the fiscal year ended October 31,
1998, the Aggressive Growth Fund paid the following commissions to Fred Alger &
Company, Incorporated:

      Commencing on January 1, 1996, a non-qualified deferred compensation plan
(the "Plan") became available to Trustees who are not interested persons of the
Fund. Under the Plan, compensation may be deferred that would otherwise be
payable by the Fund and/or WRL Series Fund, Inc., to a Disinterested Trustee or
Director on a current basis for services rendered as Trustee or Director.
Deferred compensation amounts will accumulate based on the value of Class A
shares of a Fund (without imposition of sales charge), as elected by the
Trustee. It is not anticipated that the Plan will have any impact on the Funds.
    
           The following table provides compensation amounts paid to
Disinterested Trustees of the Fund for the fiscal year ended October 31, 1998.

perform all of the functions which may be performed by the Board of Trustees,
except as set forth in the Declaration of Trust and By-Laws of the Fund or as
prohibited by applicable law.

                               PURCHASE OF SHARES
   
           As stated in the Prospectus, each Fund offers investors a choice of
three classes of shares. (The Growth Fund also includes a fourth class, Class T
shares, which are not available for new investors.) Class A, Class B or Class C
shares of a Fund can be purchased through ISI or through broker-dealers or other
financial institutions that have sales agreements with ISI. Shares of each Fund
are sold at the net asset value per share as determined at the close of the
regular session of business on the New York Stock Exchange next occurring after
a purchase order is received and accepted by the Funds. (The applicable sales
charge is added in the case of Class A and Class T shares.) The Prospectus
contains detailed information about the purchase of Fund shares.

                               DISTRIBUTION PLANS

           As stated in the Prospectus under "Investment Advisory and Other
Services," each Fund has adopted a separate Distribution Plan pursuant to Rule
12b-1 under the 1940 Act (individually, a "Plan" and collectively, the "Plans"),
applicable to Class A, Class B and Class C shares of the Fund. CLASS T SHARES OF
THE GROWTH FUND ARE NOT SUBJECT TO ANNUAL DISTRIBUTION AND SERVICE FEES.

           In determining whether to approve the Distribution Plan and the
Distribution Agreement, the Trustees considered the possible advantages afforded
shareholders from adopting the Distribution Plan and Distribution Agreement. The
Trustees were informed by representatives of ISI that reimbursements of
distribution-related expenses by the Fund under the Distribution Plan would
provide incentives to ISI to establish and maintain an enhanced distribution
system whereby new investors will be attracted to the Funds. The Trustees
believe that improvements in distribution services should result in increased
sales of shares in the Funds. In turn, increased sales are expected to lead to
an increase in the Fund's net asset levels, which would enable the Funds to
achieve economies of scale and lower their per-share operating expenses. In
addition, higher net asset levels could enhance the investment management of the
Funds, for net inflows of cash from new sales may enable the Fund's investment
adviser and sub-adviser to take advantage of attractive investment
opportunities. Finally, reduced redemptions could eliminate the potential need
to liquidate attractive securities positions in order to raise the capital
necessary to meet redemption requests.

           Under the Plans for Class A shares (the "Class A Plans"), a Fund may
pay ISI an annual distribution fee of up to 0.35% and an annual service fee of
up to 0.25% of the average daily net assets of a Fund's Class A shares; however,
to the extent that a Fund pays service fees, the amount which a Fund may pay as
a distribution fee is reduced accordingly so that the total fees payable under
the Class A Plan may not exceed on an annualized basis 0.35% of the average
daily net assets of a Fund's Class A shares.

           Under the Plans for Class B shares (the "Class B Plans"), a Fund may
pay ISI an annual distribution fee of up to 0.75% and an annual service fee of
up to 0.25% of the average daily net assets of the Fund's Class B shares.

           Under the Plans for Class C shares (the "Class C Plans"), a Fund may
pay ISI an annual distribution fee of up to 0.75% and an annual service fee of
up to 0.25% of the average daily net assets of the Fund's Class C shares;
however, the total fee payable pursuant to the Class C Plan may not on an
annualized basis, exceed 0.90% of the average daily net assets of the Fund's
Class C shares.
    

           ISI may use the fees payable under the Class A, Class B and Class C
Plans as it deems appropriate to pay for activities or expenses primarily
intended to result in the sale of the Class A, Class B or Class C shares,
respectively, or in personal service to and/or maintenance of these shareholder
accounts. For each class, these activities and expenses may include, but are not
limited to:

           /bullet/ Compensation to employees of ISI;
           /bullet/ Compensation to and expenses of ISI and other selected
                    dealers who engage in or otherwise support the distribution
                    of shares or who service shareholder accounts;
           /bullet/ The costs of printing and distributing prospectuses,
                    statements of additional information and reports for other
                    than existing shareholders; and
           /bullet/ The cost of preparing, printing and distributing sales
                    literature and advertising materials.

           Under the Plans, as required by Rule 12b-1, the Board of Trustees
will review, at least quarterly, a written report provided by ISI of the amounts
expended by ISI in distributing and servicing Class A, Class B or Class C shares
of the Funds and the purpose for which such expenditures were made. For so long
as the Plans are in effect, selection and nomination of the Trustees who are not
interested persons of the Fund shall be committed to the discretion of the
Trustees who are not interested persons of the Fund.

   
           A Plan may be terminated as to a class of shares of a Fund at any
time by vote of a majority of the non-interested Trustees, or by vote of a
majority of the outstanding voting securities of the applicable class. A Plan
may be amended by vote of the Trustees, including a majority of the
non-interested Trustees who are not interested persons of the Funds and have no
direct or indirect financial interest in the operation of the Plan or any
agreement relating thereto ("non-interested Trustees"), cast in person at a
meeting called for that purpose. Any amendment of a Plan that would materially
increase the costs to a particular class of shares of a Fund requires approval
by the shareholders of that class. A Plan will remain in effect for successive
one year periods, so long as such continuance is approved annually by vote of
the Funds' Trustees, including a majority of the non-interested Trustees, cast
in person at a meeting called for the purpose of voting on such continuance.
    

                                DISTRIBUTION FEES
   
           Distribution related expenses incurred by ISI for the fiscal year
ended October 31, 1998 are listed in the table below. These expenses have been
partially reimbursed to ISI by a 12b-1 arrangement with the Funds.

           * Class T shares of the Growth Fund are not subject to annual
distribution and service fees.
    

           No expenses are listed for the Blue Chip, Dividend Growth, Mid-Cap
Opportunities, Mid-Cap Summit or Small Cap Frontier Funds as these Funds
commenced operations March 1, 1999.

                          NET ASSET VALUE DETERMINATION
   
Net asset value is determined separately for each class of shares of a Fund on
each day as of the close of the regular session of business on the New York
Stock Exchange (the "Exchange"), currently 4:00 p.m. Eastern Time, Monday
through Friday, except on: (i) days on which changes in the value of portfolio
securities will not materially affect the net asset value of a particular class
of shares of the Fund; (ii) days during which no shares of a Fund are tendered
for redemption and no orders to purchase shares of that Fund are received; or
(iii) customary national holidays on which the Exchange is closed. The per share
net asset value of each class of shares of a Fund is determined by dividing the
total value of the Fund's securities, receivables and other assets allocable to
that class by the total number of shares outstanding of that class. The public
offering price of a Class A, Class B, Class C or Class T share of a Fund is the
net asset value per share plus, the applicable sales charge in the case of Class
A or Class T shares. Investment securities are valued at the closing price for
securities traded on a principal securities exchange (U.S. or foreign), or on
the NASDAQ National Market. Investment securities traded on the over-the-counter
market and listed securities for which no sales are reported for the trading
period immediately preceding the time of determination are valued at the last
bid price. Foreign currency denominated assets and liabilities are converted
into U.S. dollars at the closing exchange rate each day. Other securities for
which quotations are not readily available are valued at fair values determined
in such manner as a Fund's sub-adviser, under the supervision of the Board of
Trustees, decides in good faith. (No information is included in the chart below
for the Blue Chip, Dividend Growth, Mid-Cap Opportunities, Mid-Cap Summit or
Small Cap Frontier Funds as these Funds commenced operations March 1, 1999.)

                        DIVIDENDS AND OTHER DISTRIBUTIONS
   
      An investor may choose among several options with respect to dividends and
capital gain distributions payable to the investor. Dividends or other
distributions will be paid in full and fractional shares at the net asset value
determined as of the ex-dividend date unless the shareholder has elected another
distribution option as described in the Prospectus. Transaction confirmations
and checks for payments designated to be made in cash generally will be mailed
on the payable date. The per share income dividends on Class B and Class C
shares of a Fund are anticipated to be lower than the per share income dividends
on Class A shares of that Fund, (and Class T shares of the Growth Fund) as a
result of higher distribution and service fees applicable to the Class B and
Class C shares.
    
                              SHAREHOLDER ACCOUNTS

      Detailed information about general procedures for Shareholder Accounts and
specific types of accounts is set forth in the Prospectus.

                                RETIREMENT PLANS
   
      The Funds offer several types of retirement plans that an investor may
establish to invest in shares of a Fund with tax deductible dollars. Prototype
retirement plans for both corporations and self-employed individuals, and for
Individual Retirement Accounts, Code Section 401(k) Plans and Simplified
Employee Pension Plans are available by calling or writing IDEX Customer
Service. These plans require the completion of separate applications which are
also available from IDEX Customer Service. Investors Fiduciary Trust Company
("IFTC"), Kansas City, Missouri, acts as the custodian or trustee under these
plans for which it charges an annual fee of up to $15.00 on each such account
with a maximum of $30.00 per tax identification number. However, if your
retirement plan is under custody of IFTC and your combined retirement account
balances per taxpayer ID number are more than $50,000, there is generally no
fee. Shares of a Fund are also available for investment by Code Section
403(b)(7) retirement plans for employees of charities, schools, and other
qualifying employers. The Tax Exempt Fund is not well-suited as an investment
vehicle for tax-deferred retirement plans which cannot benefit from tax-exempt
income and whose distributed earnings are taxable to individual recipients as
ordinary income. To receive additional information or forms on these plans,
please call IDEX Customer Service at (888) 233-4339 (toll free) or write the
Idex Investor Services, Inc. at P. O. Box 9015, Clearwater, Florida 33758-9015.
No contribution to a retirement plan can be made until the appropriate forms to
establish the plan have been completed. It is advisable for an investor
considering the funding of any retirement plan to consult with an attorney,
retirement plan consultant or financial or tax advisor with respect to the
requirements of such plans and the tax aspects thereof.
    
                              REDEMPTION OF SHARES

      Shareholders may redeem their shares at any time at any price equal to the
net asset value per share next determined following receipt of a valid
redemption order by the transfer agent, in proper form. Payment will ordinarily
be made within three days of the receipt of a valid redemption order. The value
of shares on redemption may be more or less than the shareholder's cost,
depending upon the market value of the Fund's net assets at the time of
redemption. CLASS B SHARES, CLASS C SHARES PURCHASED AFTER FEBRUARY 28, 1999 AND
CERTAIN CLASS A SHARE PURCHASES ARE ALSO SUBJECT TO A CONTINGENT DEFERRED SALES
CHARGE UPON CERTAIN REDEMPTIONS. THE PROSPECTUS DESCRIBES THE REQUIREMENTS AND
PROCEDURES FOR THE REDEMPTION OF SHARES.
   
      Shares will normally be redeemed for cash, although each Fund retains the
right to redeem its shares in-kind under unusual circumstances in order to
protect the interests of the remaining shareholders by the delivery of
securities selected from its assets at its discretion. The Fund has, however,
elected to be governed by Rule 18f-1 under the 1940 Act pursuant to which the
Fund is obligated to redeem shares solely in cash up to the lesser of $250,000
or 1% of the net asset value of a Fund during any 90-day period for any one
shareholder. Should redemptions by any shareholder exceed such limitation, the
Funds will have the option of redeeming the excess in cash or in kind. If shares
are redeemed in kind, the redeeming shareholder might incur brokerage costs in
converting the assets to cash. The method of valuing securities used to make
redemptions in kind will be the same as the method of valuing portfolio
securities described under "Net Asset Value Determination," and such valuation
will be made as of the same time the redemption price is determined. Upon any
distributions in-kind, shareholders may appeal the valuation of such securities
by writing to the Funds.
    
      Redemption of shares may be suspended, or the date of payment may be
postponed, whenever: (1) trading on the Exchange is restricted, as determined by
the SEC, or the Exchange is closed except for holidays and weekends; (2) the SEC
permits such suspension and so orders; or (3) an emergency exists as determined
by the SEC so that disposal of securities and determination of net asset value
is not reasonably practicable.

      The Contingent Deferred Sales Charge ("CDSC") is waived on redemptions of
Class B and Class C shares in the circumstances described below:

                                       60
<PAGE>

     (a)     REDEMPTION UPON TOTAL DISABILITY OR DEATH

     The Fund will waive the CDSC on redemptions following the death or total
disability (as evidenced by a determination of the federal Social Security
Administration) of a Class B or C shareholder, but in the case of total
disability only as to shares owned at the time of the initial determination of
disability. The Transfer Agent or Distributor will require satisfactory proof of
death or disability before it determines to waive the CDSC.

     (b)     REDEMPTION PURSUANT TO A FUND'S SYSTEMATIC WITHDRAWAL PLAN

     A shareholder may elect to participate in a systematic withdrawal plan
("Plan") with respect to the shareholder's investment in the Fund. Under the
Plan, a dollar amount of a participating shareholder investment in the Fund will
be redeemed systematically by the Fund on a periodic basis, and the proceeds
paid in accordance with shareholder's instructions. The amount to be redeemed
and frequency of the systematic withdrawals will be specified by the shareholder
upon his or her election to participate in the Plan. The CDSC will be waived on
redemptions made under the Plan subject to the limitations described below.
   
     The amount of a shareholder's investment in a Fund at the time election to
participate in the Plan is made with respect to the Fund is hereinafter referred
to as the "Initial Account Balance." The amount to be systematically redeemed
from a Fund without the imposition of a CDSC may not exceed a maximum of 12%
annually of the shareholder's Initial Account Balance. The Funds reserve the
right to change the terms and conditions of the Plan and the ability to offer
the Plan.
    
     (c)     REINVESTMENT PRIVILEGE

     The CDSC is also waived on redemption of Class B or C shares as it relates
to the reinvestment of redemption proceeds in the same class of shares of
another IDEX Fund within 90 days after redemption.

     (d)     CERTAIN RETIREMENT PLAN WITHDRAWALS
   
     The Fund will waive the CDSC on withdrawals from IRS qualified and
nonqualified retirement plans, individual retirement accounts, tax- sheltered
accounts, and deferred compensation plans, where such withdrawals are permitted
under the terms of the plan or account (E.G., attainment of age 59-1/2,
separation from service, death, disability, loans, hardships, withdrawals of
excess contributions pursuant to applicable IRS rules or withdrawals based on
life expectancy under applicable IRS rules). This waiver does not include
transfer of asset redemptions, broker directed accounts or omnibus accounts.
    
                                     TAXES
   
         Each Fund has qualified, and intends to continue to qualify, for
treatment as a regulated investment company ("RIC") under the Internal Revenue
Code of 1986, as amended (the "Code"). In order to qualify for that treatment,
each Fund must distribute to its shareholders for each taxable year at least 90%
of its investment company taxable income (consisting generally of taxable net
investment income and net short-term capital gain) and must meet several
additional requirements. With respect to each Fund, these requirements include
the following: (1) the Fund must derive at least 90% of its gross income each
taxable year from dividends, interest, payments with respect to securities loans
and gains from the sale or other disposition of securities, or other income
(including gains from futures contracts) derived with respect to its business of
investing in securities; (2) the Fund must derive less than 30% of its gross
income each taxable year from the sale or other disposition of securities or
futures contracts that were held for less than three months (the "Short-Short
Limitation") (however, this requirement has been repealed for tax years
beginning after August 5, 1997); (3) at the close of each quarter of the Fund's
taxable year, at least 50% of the value of its total assets must be represented
by cash and cash items, U.S. government securities, securities of other RICs and
other securities, with these other securities limited, in respect of any one
issuer, to an amount that does not exceed 5% of the value of the Fund's total
assets and that does not represent more than 10% of the outstanding voting
securities of the issuer; and (4) at the close of each quarter of the Fund's
taxable year, not more than 25% of the value of its total assets may be invested
in securities (other than U.S. government securities or the securities of other
RICs) of any one issuer.

         A Fund will be subject to a nondeductible 4% excise tax to the extent
it fails to distribute by the end of any calendar year substantially all of its
ordinary income for that year and capital gain net income for the one-year
period ending on October 31 of that year, plus certain other amounts. Each Fund
intends to distribute annually a sufficient amount of any taxable income and
capital gains so as to avoid liability for this excise tax.
    

                                       61
<PAGE>
   
         If the Tax-Exempt Fund invests in any instruments that generate taxable
income, distributions of the interest earned thereon will be taxable to that
Fund's shareholders as ordinary income to the extent of its earnings and
profits. Moreover, if that Fund realizes capital gains as a result of market
transactions, any distributions of that gain also will be taxable to its
shareholders.

         Proposals may be introduced before Congress for the purpose of
restricting or eliminating the federal income tax exemption for interest on
municipal securities. If such a proposal were enacted, the availability of
municipal securities for investment by the Tax-Exempt Fund and the value of its
portfolio securities would be affected. In that event, the Tax-Exempt Fund will
re-evaluate its investment objective and policies.

         Dividends and interest received by a Fund may be subject to income,
withholding or other taxes imposed by foreign countries and U.S. possessions
that would reduce the yield on its securities. However, tax conventions between
certain countries and the United States may reduce or eliminate these foreign
taxes, and foreign countries generally do not impose taxes on capital gains in
respect of investments by foreign investors. If more than 50% of the value of
the Global Fund's total assets at the close of its taxable year consists of
securities of foreign corporations, it will be eligible to, and may, file an
election with the Internal Revenue Service that will enable its shareholders, in
effect, to receive the benefit of the foreign tax credit with respect to any
foreign and U.S. possessions income taxes paid by it.

         Pursuant to the election, a Fund will treat those taxes as dividends
paid to its shareholders and each shareholder will be required to: (1) include
in gross income, and treat as paid by him, his proportionate share of those
taxes; (2) treat his share of those taxes and of any dividend paid by the Fund
that represents income from foreign or U.S. possessions sources as his own
income from those sources; and (3) either deduct the taxes deemed paid by him in
computing his taxable income or, alternatively, use the foregoing information in
calculating the foreign tax credit against his federal income tax. The Global
Fund will report to its shareholders shortly after each taxable year their
respective shares of the income from sources within, and taxes paid to, foreign
countries and U.S. possessions if it makes this election.

         Each Fund, except the Tax-Exempt Fund, may invest in the stock of
"passive foreign investment companies" ("PFICs"). A PFIC is a foreign
corporation that, in general, meets either of the following tests: (1) at least
75% of its gross income is passive; or (2) an average of at least 50% of its
assets produce, or are held for the production of, passive income. Under certain
circumstances, a Fund will be subject to federal income tax on a portion of any
"excess distribution" received on the stock of a PFIC or of any gain on
disposition of that stock (collectively "PFIC income"), plus interest thereon,
even if the Fund distributes the PFIC income as a taxable dividend to its
shareholders. The balance of the PFIC income will be included in the Fund's
investment company taxable income and, accordingly, will not be taxable to it to
the extent that income is distributed to its shareholders. If a Fund invests in
a PFIC and elects to treat the PFIC as a "qualified electing fund," then in lieu
of the foregoing tax and interest obligation, the Fund will be required to
include in income each year its pro rata share of the qualified electing fund's
annual ordinary earnings and net capital gain (the excess of net long-term
capital gain over net short-term capital loss). This will occur even if they are
not distributed to the Fund and those amounts would be subject to the
distribution requirements described above. In most instances it will be very
difficult, if not impossible, to make this election because of certain
requirements thereof.

         The use of hedging strategies, such as writing (selling) and purchasing
options and futures contracts and entering into forward contracts, involves
complex rules that will determine for income tax purposes the character and
timing of recognition of the income received in connection therewith by a Fund.
Income from foreign currencies (except certain gains therefrom that may be
excluded by future regulations), and income from transactions in options,
futures and forward contracts derived by a Fund with respect to its business of
investing in securities or foreign currencies, will qualify as permissible
income under the Income Requirement. However, income from the disposition of
foreign currencies that are not directly related to the Fund's principal
business of investing in securities (or options and futures with respect
thereto) also will be subject to the Short-Short Limitation if the securities
are held for less than three months; however, the Short-Short Limitation has
been repealed for federal tax purposes for tax years beginning after August 5,
1997. In states where the limitation has not been formally repealed, such as
California and Massachusetts, the states have indicated that they will not
enforce the limitation for tax years beginning after August 5, 1997.

         If a Fund satisfies certain requirements, any increase in value on a
position that is part of a "designated hedge" will be offset by any decrease in
value (whether realized or not) of the offsetting hedging position during the
period of the hedge for purposes of determining whether the Fund satisfies the
Short-Short Limitation. Thus, only the net gain (if any) from the designated
hedge will be included in gross income for purposes of that limitation. Each
Fund intends that, when it engages in hedging transactions, they will qualify
for this treatment, but at the present time it is not clear whether this
treatment will be available for all of the Fund's hedging transactions. To the
extent this treatment is not available, a Fund may be forced to defer the
closing out of certain options and futures contracts beyond the time when it
otherwise would be advantageous to do so, in order for the Fund to continue to
qualify as an RIC.

         The treatment of income dividends and capital gain distributions by a
Fund to shareholders under the various state income tax laws may not parallel
that under the federal law. Qualification as a regulated investment company does
not involve supervision of a Fund's management or of its investment policies and
practices by any governmental authority.

interest of the Growth Fund.
    
                                  MISCELLANEOUS

ORGANIZATION
   
         Each Fund is a series of the IDEX Mutual Funds, a Massachusetts
business trust that was formed by a Declaration of Trust dated January 7, 1986.
The Trust currently is governed by a Restatement of Declaration of Trust
("Declaration of Trust") dated as of August 30, 1991.

         On October 1, 1993, in a tax-free reorganization, the Flexible Income
Fund acquired all of the assets and assumed all of the liabilities of IDEX Total
Income Trust ("IDEX Total") in exchange for shares of the Flexible Income Fund
which were then distributed to IDEX Total shareholders. All historical financial
and performance information set forth in this Statement of Additional
Information relates to IDEX Total prior to the date it was reorganized into the
Flexible Income Fund.

         On September 20, 1996 in a tax-free reorganization, IDEX Growth Fund
(formerly IDEX II Growth Fund) acquired all of the assets and assumed all of the
liabilities of IDEX Fund and IDEX Fund 3 in exchange for Class T shares of IDEX
Growth Fund which were then distributed on a pro rata basis to the respective
shareholders of IDEX Fund and IDEX Fund 3. Upon closing of the reorganization,
IDEX II Series Fund changed its name to IDEX Series Fund. IDEX Series Fund
became IDEX Mutual Funds effective March 1, 1999.
    

SHARES OF BENEFICIAL INTEREST
   
         The Declaration of Trust permits the Funds to issue an unlimited number
of shares of beneficial interest. Shares of the Funds are fully paid and
nonassessable when issued. Shares of the Funds have no preemptive, cumulative
voting, conversion or subscription rights. Shares of the Funds are fully
transferable but the Funds are not bound to recognize any transfer until it is
recorded on the books.

         The shares of beneficial interest of each Fund are divided into three
classes, Class A, Class B and Class C shares; the Growth Fund includes a fourth
class, Class T shares. Each class represents interests in the same assets of the
Fund and differ as follows: each class of shares has exclusive voting rights on
matters pertaining to its plan of distribution or any other matter appropriately
limited to that class; Class A shares are subject to an initial sales charge;
Class B shares are subject to a contingent deferred sales charge, or back-end
load, at a declining rate; Class C shares are subject to an initial sales charge
and are subject to a contingent deferred sales charge if redeemed within 18
months of purchase; Class B and Class C shares are subject to higher ongoing
distribution and service fees; each class may bear differing amounts of certain
class-specific expenses; and each class has a separate exchange privilege. Class
T shares of the Growth Fund are subject to an initial sales charge, but no
annual distribution and service fees. Class T shares are NOT available to new
investors; only existing Class T shareholders (who were shareholders of IDEX
Fund or IDEX Fund 3 on September 20, 1996) may purchase additional Class T
shares. The Funds do not anticipate that there will be any conflicts between the
interests of holders of the different classes of shares of the same Fund by
virtue of these classes. On an ongoing basis, the Board of Trustees will
consider whether any such conflict exists and, if so, take appropriate action.
On any matter submitted to a vote of shareholders of a series or class, each
full issued and outstanding share of that series or class has one vote.

         The Declaration of Trust provides that each of the Trustees will
continue in office until the termination of the Trust or his earlier death,
resignation, bankruptcy or removal. A meeting will be called for the election of
trustees upon the written request of holders of 10% or more of the outstanding
shares of the Funds. Vacancies may be filled by majority of the remaining
trustees, subject to certain limitations imposed by the 1940 Act. Therefore, it
is not anticipated that annual or regular meetings of shareholders normally will
be held, unless otherwise required by the Declaration of Trust or the 1940 Act.
Subject to the foregoing, shareholders have the power to vote for the election
and removal of trustees, to
    
                                       63
<PAGE>
   
terminate or reorganize the Funds, to amend the Declaration of Trust, on whether
to bring certain derivative actions and on any other matters on which a
shareholder vote is required by the 1940 Act, the Declaration of Trust, the
Funds' bylaws or the Trustees.

REGISTRATION STATEMENT
   
         This Statement of Additional Information and the Prospectuses for the
Funds do not contain all the information set forth in the registration statement
and exhibits relating thereto, which the Funds have filed with the SEC,
Washington, D.C. under the 1933 Act and the 1940 Act, to which reference is
hereby made.
    
                             PERFORMANCE INFORMATION
   
         Quotations of average annual total return for a particular class of
shares of a Fund will be expressed in terms of the average annual compounded
rate of return of a hypothetical investment in the Fund over periods of 1, 5,
and 10 years. These are the average annual compounded rates of return that would
equate the initial amount invested to the ending redeemable value. These rates
of return are calculated pursuant to the following formula:
    
                                 P(1 + T)N = ERV
   
(where P = a hypothetical initial investment of $1,000; T = the average annual
total return; N = the number of years; and ERV = the ending redeemable value of
a hypothetical $1,000 investment made at the beginning of the period). All
average annual total return figures reflect the deduction of a proportionate
share of each Fund's expenses on an annual basis, and assume that the maximum
sales load (Class A and Class T shares) is deducted from the initial $1,000
investment and all dividends and distributions are paid in additional shares.

         The current yield for a particular class of shares of each of the
Flexible Income, Tax-Exempt, Income Plus, Balanced or Strategic Total Return
Funds is computed in accordance with a standardized method prescribed by rules
of the SEC. The yield is computed by dividing the Fund's investment income per
share earned during a particular 30-day base period (including dividends, if any
and interest earned, minus expenses excluding reductions for affiliated
brokerage and custody earnings credits accrued during the period) by the maximum
offering price per share on the last day of the base period and then annualizing
the result.

         The tax equivalent yield of the Tax-Exempt Fund is computed by dividing
that portion of the yield (as computed above) which is tax-exempt by one minus
an assumed tax rate of 28% and adding the product to that portion, if any, of
the Fund's yield that is not tax-exempt. The tax equivalent yield of the
Tax-Exempt Fund's Class A, Class B and Class C shares based on a 30-day period
ended October 31, 1998 was %, % and %, respectively.

                                   APPENDIX A
   
                CERTAIN SECURITIES IN WHICH THE FUNDS MAY INVEST
I. MUNICIPAL OBLIGATIONS IN WHICH THE TAX-EXEMPT FUND MAY INVEST
    
A.   MUNICIPAL BONDS

     GENERAL INFORMATION. Municipal Bonds are debt obligations issued to obtain
funds for various public purposes, including the construction of a wide range of
public facilities such as airports, highways, bridges, schools, hospitals,
housing, mass transportation, streets and water and sewer works, and that pay
interest that is exempt from federal income tax in the opinion of issuer's
counsel. Other public purposes for which Municipal Bonds may be issued include
the refunding of outstanding obligations, obtaining funds for general expenses
and obtaining funds to lend to other public institutions and facilities.

     The two principal classifications of Municipal Bonds are "general
obligation" bonds and "revenue" or "special tax" bonds. General obligation bonds
are secured by the issuer's pledge of its full faith, credit and taxing power
for the payment of principal and interest. Revenue or special tax bonds are
payable only from the revenues derived from a particular facility or class of
facilities or project or, in some cases, from the proceeds of a special excise
tax or other specific revenue source, but are not supported by the issuer's
power to levy general taxes. Most industrial development bonds are in this
category.

     There are, of course, variations in the security of Municipal bonds, both
within a particular classification and between classifications, depending on
numerous factors. The yields of Municipal Bonds depend, among other things, upon
general money market conditions, general conditions of the Municipal Bond
market, size of a particular offering, the maturity of the obligations and
rating of the issue.

     INDUSTRIAL DEVELOPMENT BONDS AND PRIVATE ACTIVITY BONDS. Industrial
development bonds ("IDBs") and private activity bonds ("PABs") are issued by or
on behalf of public authorities to finance various privately operated
facilities, such as airports or pollution control facilities. PABs generally are
such bonds issued after August 15, 1986. These obligations are included within
the term "municipal bonds" if the interest paid thereon is exempt from federal
income tax in the option of the bond counsel. IDBs and PABs are in most cases
revenue bonds and thus are not payable from the unrestricted revenues of the
issuer. The credit quality of IDBs and PABs is usually directly related to the
credit standing of the user of the facilities being financed.
   
     PURCHASES ON "WHEN-ISSUED" OR "DELAYED DELIVERY" BASIS. Sometimes the
Tax-Exempt Fund may buy Municipal Bonds on a "when-issued" or "delayed delivery"
basis. This means that when it agrees to buy, the terms of the Bonds and the
price it will pay are fixed, but it does not purchase and take delivery of the
Bonds until a later date (the "settlement date"), which is usually within one
month. The Tax-Exempt Fund pays no money and receives no interest before the
settlement date. The commitment to purchase securities on a when-issued or
delayed delivery basis involves the risk that the market value of such
securities may fall below cost prior to the settlement date. While the
Tax-Exempt Fund may sell the Municipal Bonds before the settlement date, it will
ordinarily do so only for investment management reasons. Ordinarily, the
Tax-Exempt Fund purchases Municipal Bonds that it has agreed to buy on a
when-issued or delayed delivery basis. Gains or losses on sales prior to the
settlement date are not tax-exempt.
    
     A Municipal Bond purchased on a when-issued or delayed delivery basis is
recorded as an asset on the commitment date. The Tax-Exempt Fund will direct the
Fund's custodian to segregate cash, U.S. Government securities or other
appropriate debt obligations owned by the Fund that are at least equal in value
to the amount the Tax-Exempt Fund will have to pay on the settlement date. If
necessary, additional assets will be placed in the account daily so that the
value of the account will at least equal the Fund's purchase commitment.

     B.  MUNICIPAL NOTES
   
     The Tax-Exempt Fund may invest in the following types of Municipal Notes,
subject to the quality requirements described in the Prospectus:
    

                                        1
<PAGE>

     PROJECT NOTES. Project notes ("PNs") are issued on behalf of local
authorities at auctions conducted by the United States Department of Housing and
Urban Development to raise funds for federally sponsored urban renewal,
neighborhood development and housing programs. PNs are backed by the full faith
and credit of the Federal government through agreements with the local authority
which provide that, if required, the Federal government will lend the issuer an
amount equal to the principal of and interest on the PNs. Ordinarily, PNs are
repaid by rolling over the notes or from the proceeds of new bonds or other
securities which are issued to provide permanent financing.

     BOND ANTICIPATION NOTES. Bond anticipation notes ("BANs") are usually
general obligations of state and local governmental issuers which are sold to
obtain interim financing for projects that will eventually be funded through the
sale of long-term debt obligations or bonds. The ability of an issuer to meet
its obligations on its BANs is primarily dependent on the issuer's access to the
long-term municipal bond market and the likelihood that the proceeds of such
bond sales will be used to pay the principal and interest on the BANs.

     TAX ANTICIPATION NOTES. Tax anticipation notes ("TANs") are issued by state
and local governments to finance their current operations. Repayment is
generally to be derived from specific future tax revenues. TANs are usually
general obligations of the issuer. A weakness in an issuer's capacity to raise
taxes due to, among other things, a decline in its tax base or a rise in
delinquencies, could adversely affect the issuer's ability to meet its
obligations on outstanding TANs.

     REVENUE ANTICIPATION NOTES. Revenue anticipation notes ("RANs") are issued
by governments or governmental bodies with the expectation that future revenues
from a designated source will be used to repay the notes. In general, they also
constitute general obligations of the issuer. A decline in the receipt of
projected revenues, such as anticipated revenues from another level of
government, could adversely affect an issuer's ability to meet its obligations
on outstanding RANs. In addition, the possibility that the revenues would, when
received, be used to meet other obligations could affect the ability of the
issuer to pay the principal and interest on RANs.

     CONSTRUCTION LOAN NOTES. Construction loan notes are issued to provide
construction financing for specific projects. Frequently, these notes are
redeemed with funds obtained from the Federal Housing Administration.
   
     BANK NOTES. Bank notes are notes issued by local governmental bodies and
agencies as those described above to commercial banks as evidence of borrowings.
Banks on occasion sell such notes to purchasers such as the Tax-Exempt Fund. The
purposes for which the notes are issued vary, but bank notes are frequently
issued to meet short-term working-capital or capital-project needs. These notes
typically are redeemed with revenue from taxes or from long-term financing
proceeds, and may have risks similar to the risks associated with TANs and RANs.
    
     C.  MUNICIPAL COMMERCIAL PAPER

     Municipal Commercial Paper (also called "short-term discount notes")
represents short-term obligations of state and local governments and their
agencies issued typically to meet seasonal working capital or interim
construction financing requirements. Municipal Commercial Paper is often issued
at a discount, with shorter maturities than Municipal Notes. Such obligations
are repayable from general revenues of the issuer or refinanced with long-term
debt. In most cases, Municipal Commercial Paper is backed by letters of credit,
lending or note repurchase agreements, or other credit facility agreements
offered by banks or other institutions.
   
     While the various types of Municipal Notes and Municipal Commercial Paper
described above as a group represent the major portion of the tax-exempt note
market, other types of notes are occasionally available in the marketplace and
the Tax-Exempt Fund may invest in such other types of notes to the extent
permitted under its investment objective and policies. Such short-term
obligations may be issued for different purposes and with different security
than those mentioned above.
    

                                        2
<PAGE>

     D.  FLOATING RATE AND VARIABLE RATE OBLIGATIONS
   
     The Tax-Exempt Fund may purchase floating rate and variable rate
obligations, including participation interests therein (see section E below).
Investments in floating or variable rate securities normally will include IDBs
which provide that the rate of interest is set as a specific percentage of a
designated base rate, such as the rate on Treasury Bonds or Bills or the prime
rate at a major commercial bank, and that the Fund can demand payment of the
obligation on short notice at par value plus accrued interest. Variable rate
securities provide for a specified periodic adjustment in the interest rate,
while floating rate securities have flexible rates that change whenever there is
a change in the designated base interest rate. Frequently, such securities are
secured by letters of credit or other credit support arrangements provided by
banks. The quality of the underlying creditor (i.e., the corporation utilizing
the IDBs financing) or the bank, as the case may be, must be equivalent to the
Municipal Obligation ratings required for purchases for the Tax-Exempt Fund.
    
     E.  PARTICIPATION INTERESTS
   
     The Tax-Exempt Fund may invest in participation interests purchased from
banks in variable rate tax-exempt securities (such as IDBs) owned by the banks.
A participation interest gives the purchaser an undivided interest in the
tax-exempt security in the proportion that the Fund's participation interest
bears to the total principal amount of the tax-exempt security, and permits
demand repurchase as described in section D above. Participations are frequently
backed by an irrevocable letter of credit or guarantee of the bank offering the
participation which the sub-adviser, under the supervision of the Board of
Trustees, has determined meets the prescribed quality standards for the
Tax-Exempt Fund. The Fund has the right to sell the instrument back to the bank
and draw on the letter of credit on 7 days' notice for all or any part of the
Fund's participation interest in the tax-exempt security, plus accrued interest.
The Fund intends to exercise its demand rights under the letter of credit only
(1) upon a default under the terms of the tax-exempt security, (2) as needed to
provide liquidity in order to meet redemptions, or (3) upon a drop in the rating
or the sub-adviser's evaluation of the underlying security. Banks charge a
service and letter of credit fee and a fee for issuing repurchase commitments in
an amount equal to the excess of the interest paid on the tax-exempt securities
over the yield negotiated between the Fund and the bank at which the instruments
were purchased by the Tax-Exempt Fund. The sub-adviser will monitor the pricing,
quality and liquidity of the variable rate demand instruments held by the
Tax-Exempt Fund, including the IDBs supported by bank letters of credit or
guarantee, on the basis of published financial information, reports or rating
agencies and other bank analytical services. Participation interests will be
purchased only if, in the opinion of counsel, interest income on such interest
will be tax-exempt when distributed as dividends to shareholders.
    
     Obligations of issuers of Municipal Bonds, Municipal Notes and Municipal
Commercial Paper are subject to the provisions of bankruptcy, insolvency and
other laws affecting the rights and remedies of creditors, such as the Federal
Bankruptcy Act, and laws, if any, which may be enacted by Congress or state
legislatures extending the time for payment of principal or interest, or
imposing other constraints upon enforcement of such obligations or upon
municipalities' power to levy taxes. There is also the possibility that
litigation or other conditions may materially affect the power or ability of an
issuer to pay, when due, the principal of and interest on its Municipal
Obligations.

II.  OBLIGATIONS IN WHICH EACH FUND MAY INVEST
     (UNLESS OTHERWISE NOTED)
   
     The Funds may invest in the following obligations for temporary defensive
purposes or as otherwise described in the prospectus.
    
     A.  U.S. GOVERNMENT OBLIGATIONS
   
     As described in the Prospectus, the Funds may invest in some or all of the
following types of direct obligations of the Federal Government, issued by the
Department of the Treasury, and backed by the full faith and credit of the
Federal Government.
    
     TREASURY BILLS. Treasury bills are issued with maturities of up to one
year. They are issued in bearer form, are sold on a discount basis and are
payable at par value at maturity.

     TREASURY NOTES. Treasury Notes are longer-term interest bearing obligations
with original maturities of one to seven years.

                                        3
<PAGE>

     TREASURY BONDS. Treasury bonds are longer-term interest bearing obligations
with original maturities from 5 to 30 years.

     B.  OBLIGATIONS OF FEDERAL AGENCIES, INSTRUMENTALITIES AND AUTHORITIES

     Certain federal agencies have been established as instrumentalities of the
United States Government to supervise and finance certain types of activities.
These agencies include, but are not limited to, the Banks for Cooperatives,
Federal Land Banks, Federal Intermediate Credit Banks, Federal Home Loan Banks
("FHLB"), Federal National Mortgage Association ("FNMA"), Government National
Mortgage Association ("GNMA"), Export-Import Bank of the United States, and
Tennessee Valley Authority ("TVA"). Issues of these agencies, while not direct
obligations of the United States Government, are either backed by the full faith
and credit of the United States (e.g., GNMA Certificates or certain TVA Bonds)
or are guaranteed by the Treasury (e.g., certain other TVA Bonds) or supported
by the issuing agencies' right to borrow from the Treasury (e.g., FHLB and FNMA
Bonds). There can be no assurance that the United States Government itself will
pay interest and principal on securities as to which it is not legally obligated
to do so.

     C. CERTIFICATES OF DEPOSIT (ALL FUNDS) AND TIME DEPOSITS (INCOME PLUS FUND
ONLY)

     A time deposit is a non-negotiable interest-bearing deposit with a bank
which generally cannot be withdrawn prior to a specified maturity date without
substantial interest penalties. A certificate of deposit ("CD") is a negotiable
instrument issued by a bank against a time deposit. CDs normally can be traded
in the secondary market prior to maturity, and are thus more liquid than other
forms of time deposits. The Funds will only invest in U.S. dollar denominated
time deposits and CDs representing deposits in U.S. banks with assets of $1
billion or more, whose deposits are insured by the Federal Deposit Insurance
Corporation.

     D.  COMMERCIAL PAPER

     Commercial paper refers to short-term unsecured promissory notes issued by
commercial and industrial corporations to finance their current operations.
Commercial paper may be issued at a discount and redeemed at par, or issued at
par with interest added at maturity. The interest or discount rate depends on
general interest rates, the credit standing of the issuer, and the maturity of
the note, and generally moves in tandem with rates on large CDs and Treasury
bills. An established secondary market exists for commercial paper, particularly
that of stronger issuers which are rated by Moody's Investors Service, Inc. and
Standard and Poor's Ratings Group. Investments in commercial paper are subject
to the risks that general interest rates will rise, that the credit standing and
outside rating of the issuer will fall, or that the secondary market in the
issuer's notes will become too limited to permit their liquidation at a
reasonable price.

     E.  BANKER'S ACCEPTANCES

     A banker's acceptance is a negotiable short-term draft, generally arising
from a bank customer's commercial transaction with another party, with payment
due for the transaction on the maturity date of the customer's draft. The draft
becomes a banker's acceptance when the bank, upon fulfillment of the obligations
of the third party, accepts the draft for later payment at maturity, thus adding
the bank's guarantee of payment to its customer's own obligation. In effect, a
banker's acceptance is a post-dated certified check payable to its bearer at
maturity. Such acceptances are highly liquid, but are subject to the risk that
both the customer and the accepting bank will be unable to pay at maturity. The
Funds may invest in U.S. dollar denominated bankers' acceptances issued by U.S.
banks, their foreign branches, and by U.S. branches of foreign banks.
   
     F. REPURCHASE AGREEMENTS FOR U.S. GOVERNMENT SECURITIES (EXCEPT STRATEGIC
TOTAL RETURN FUND)

     The Funds may enter into repurchase agreements with banks and dealers for
securities of or guaranteed by the U.S. Government, under which the Fund
purchases securities and agrees to resell the securities at an agreed upon time
and at an agreed upon price. The difference between the amount the Fund pays for
the securities and the amount it receives upon resale is accrued as interest and
reflected in the Fund's net investment income. When the Fund enters into
repurchase agreements, it relies on the seller to repurchase the securities.
Failure to do so may result in a loss for the Fund if the market value of the
securities is less than the repurchase price. Under the Investment Company Act
of 1940, repurchase agreements may be considered collateralized loans by the
Fund.
    

                                        4
<PAGE>

     At the time a Fund enters into a repurchase agreement, the value of the
underlying security including accrued interest will be equal to or exceed the
value of the repurchase agreement and, for repurchase agreements that mature in
more than one day, the seller will agree that the value of the underlying
security including accrued interest will continue to be at least equal to the
value of the repurchase agreement.
   
     Although repurchase agreements carry certain risks not associated with
direct investment in securities, the Funds intend to enter into repurchase
agreements only with banks and dealers in transactions which the sub-adviser
believes present minimal credit risks in accordance with guidelines adopted by
the Trustees. To the extent that proceeds from any sales of collateral upon a
default in the counterparty's obligation to repurchase were less than the
repurchase price, the Fund would suffer a loss. If the counterpart's petitions
for bankruptcy or otherwise becomes subject to bankruptcy or liquidation
proceedings, there might be restrictions on the Fund's ability to sell the
collateral and the Fund could suffer a loss.

III. OTHER SECURITIES IN WHICH THE FUNDS MAY INVEST
    
     A.  CORPORATE DEBT SECURITIES
   
     The Funds may invest in corporate bonds, notes and debentures of long and
short maturities and of various grades, including unrated securities. Corporate
debt securities exist in great variety, differing from one another in quality,
maturity, and call or other provisions. Lower grade bonds, whether rated or
unrated, usually offer higher interest income, but also carry increased risk of
default. Corporate bonds may be secured or unsecured, senior to or subordinated
to other debt of the issuer, and, occasionally, may be guaranteed by another
entity. In addition, they may carry other features, such as those described
under "Convertible Securities" and "Variable or Floating Rate Securities," or
have special features such as the right of the holder to shorten or lengthen the
maturity of a given debt instrument, rights to purchase additional securities,
rights to elect from among two or more currencies in which to receive interest
or principal payments, or provisions permitting the holder to participate in
earnings of the issuer or to participate in the value of some specified
commodity, financial index, or other measure of value.
    
     B.  INTERNATIONAL AGENCY OBLIGATIONS
   
     The Funds may invest in bonds, notes or Eurobonds of international
agencies. Examples are securities issued by the Asian Development Bank, the
European Economic Community, and the European Investment Bank. The Funds may
also purchase obligations of the International Bank for Reconstruction and
Development which, while technically not a U.S. Government agency or
instrumentality, has the right to borrow from the participating countries,
including the United States.
    
     C.  BANK OBLIGATIONS OR SAVINGS AND LOAN OBLIGATIONS
   
     The Funds may purchase certificates of deposit, bankers' acceptances and
other debt obligations of commercial banks and certificates of deposit and other
debt obligations of savings and loan associations ("S&L's"). Certificates of
deposit are receipts from a bank or an S&L for funds deposited for a specified
period of time at a specified rate of return. Bankers' acceptance are time
drafts drawn on commercial banks by borrowers, usually in connection with
international commercial transactions. These instruments may be issued by
institutions of any size, may be of any maturity, and may be insured or
uninsured. The quality of bank or savings and loan obligations may be affected
by such factors as (a) location - the strength of the local economy will often
affect financial institutions in the region, (b) asset mix -institutions with
substantial loans in a troubled industry may be weakened by those loans, and (c)
amount of equity capital - - under-capitalized financial institutions are more
vulnerable when loan losses are suffered. The Fund manager will evaluate these
and other factors affecting the quality of bank and savings and loan obligations
purchased by the Fund, but the Fund is not restricted to obligations or
institutions which satisfy specified quality criteria.

     D.  VARIABLE OR FLOATING RATE SECURITIES

     The Funds may purchase variable rate securities that provide for automatic
establishment of a new interest rate at fixed intervals (e.g., daily, monthly,
semi-annually, etc.). Floating rate securities provide for automatic adjustment
of the interest rate whenever some specified interest rate index changes. The
interest rate on variable and floating rate securities is ordinarily determined
by reference to, or is a percentage of, a bank's prime rate, the 90-day U.S.
Treasury bill rate, the rate of return on commercial paper or bank certificates
of deposit, an index of short-term interest rates, or some other objective
measure.
   
     E.  PREFERRED STOCKS (ALL FUNDS EXCEPT THE TAX-EXEMPT FUND)
    
     Preferred stocks are securities which represent an ownership interest in a
corporation and which give the owner a prior claim over common stock on the
corporation's earnings and assets. Preferred stock generally pays quarterly
dividends. Preferred stocks may differ in many of their provisions. Among the
features that differentiate preferred stocks from one another are the dividend
rights, which may be cumulative or non-cumulative and participating or
non-participating, redemption provisions, and voting rights. Such features will
establish the income return and may affect the prospects for capital
appreciation or risks of capital loss.

     F.  CONVERTIBLE SECURITIES
   
     The Funds may invest in debt securities convertible into or exchangeable
for equity securities, or debt securities that carry with them the right to
acquire equity securities, as evidenced by warrants attached to such securities
or acquired as part of units of the securities. Such securities normally pay
less current income than securities without conversion features, but add the
potential opportunity for appreciation from enhanced value for the equity
securities into which they are convertible, and the concomitant risk of loss
from declines in those values.
    
     G.  COMMON STOCKS
   
     Each Fund (other than the Tax-Exempt Fund) invests in common stocks. The
Flexible Income Fund will consider investment in income-producing common stocks
if the yields of common stocks generally become competitive with the yields of
other income securities. Common stocks are junior to the debt obligations and
preferred stocks of an issuer. Hence, dividend payments on common stocks should
be regarded as less secure than income payments on corporate debt securities.

ITEM 25 INDEMNIFICATION
    
      Provisions relating to indemnification of the Registrant's Trustees and
employees are included in Registrant's Restatement of Declaration of Trust and
Bylaws which are incorporated herein by reference.

      Insofar as indemnification for liability arising under the Securities Act
of 1933 may be permitted to Trustees, officers and controlling persons, or
otherwise, Registrant has been advised that in the opinion of the Commission
such indemnification may be against public policy as expressed in the Act and
may be, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by Registrant of expenses
incurred or paid by a Trustee, officer or controlling person of Registrant in
the successful defense of any action, suit or proceeding) is asserted by such
Trustee, officer or controlling person in connection with the securities being
registered, Registrant will, unless in the opinion of its counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

Idex Management will act in conformity with the Fund's Declaration of Trust,
Bylaws and registration statement applicable to the Portfolios and with the
instructions and direction of the Board of Trustees of the Fund, and will
conform to and comply with the 1940 Act and all other applicable federal or
state laws and regulations.

      2. INVESTMENT ADVISORY SERVICES. In its capacity as investment adviser to
the Portfolios, Idex Management shall have the following responsibilities:

      (a) to provide a continuous investment program for each Portfolio
      including advice as to the acquisition, holding or disposition of any or
      all of the securities or other assets which the Portfolios may own or
      contemplate acquiring from time to time, consistent with the Fund's
      Declaration of Trust and each Portfolio's investment objective and
      policies adopted and declared by the Board of Trustees and stated in the
      Portfolios' current Prospectus;

<PAGE>


      (b) to cause the officers of Idex Management to attend meetings and
      furnish oral or written reports, as the Fund may reasonably require, in
      order to keep the Trustees and appropriate officers of the Fund fully
      informed as to the conditions of the investment securities of the
      Portfolios, the investment recommendations of Idex Management, and the
      investment considerations which have given rise to those recommendations;
      and

      (c) to supervise the purchase and sale of securities as directed by the
      appropriate officers of the Fund, including the selection of brokers and
      dealers to execute such transactions, consistent with paragraph 8 hereof.

      It is understood and agreed that Idex Management intends to enter into an

Investment Counsel Agreement; provided, however, that such Agreement shall be
approved by the Board of Trustees and by the holders of the outstanding voting
securities of each of the Portfolios in accordance with the requirements of
Section 15 of the 1940 Act, and shall otherwise be subject to, and contain such
provisions as shall be required by, the 1940 Act.

      3. MANAGEMENT AND ADMINISTRATIVE SERVICES. Idex Management shall furnish
or make available to the Portfolios the services of executive and management

shareholder relations, regulatory reporting and compliance, and all other
functions of the Portfolios, including supervising and coordinating the services
of the Portfolios' custodian and transfer agent. Idex Management shall also
assist in the preparation of reports to shareholders of the Portfolios and
prepare sales literature promoting sale of the Portfolios' shares as requested
by the Fund.

      4. ALLOCATION OF EXPENSES. During the term of this Agreement, each
Portfolio will bear all expenses not expressly assumed by Idex Management
incurred in the operation of each Portfolio and the offering of its shares.
Without limiting the generality of the foregoing:

      5. OBLIGATIONS OF FUND. The Fund shall have the following obligations
under the Agreement:

      (a) to keep Idex Management continuously and fully informed as to the
      composition of its investment portfolio of each Portfolio and the nature
      of all of its assets and liabilities from time to time;

      (b) to furnish Idex Management with a certified copy of any financial
      statement or report prepared for a Portfolio by certified or independent
      public accountants, and with copies of any financial statements or reports
      made to its shareholders or to any governmental body or securities
      exchange;

      (c) to furnish Idex Management with any further materials or information
      which Idex Management may reasonably request to enable it to perform its
      functions under this Agreement; and

      (d) to compensate Idex Management for its services in accordance with the
      provisions of Section 6 hereof.

      6. COMPENSATION. Each Portfolio shall pay to Idex Management for its
services a fee, computed daily and paid monthly, payable on the last day of each
month during which or part of which this Agreement is in effect, as set forth on
Schedule A attached to this Agreement, as it may be amended from time to time in
accordance with Section 15 below. For the month during which this Agreement
becomes effective and the month during which it terminates, however, there shall
be an appropriate pro-ration of the fee payable for such month based on the
number of calendar days of such month during which this Agreement is effective.

      7. TREATMENT OF INVESTMENT ADVICE. With respect to a Portfolio, the Fund
shall retain full control over its own investment policies. However, the
Trustees of the Fund may delegate to the appropriate officers of the Fund, or to
a committee of Trustees, the power to authorize purchases, sales or other
actions affecting each Portfolio in the interim between meetings of the
Trustees, provided such action is consistent with the established investment
policy of the Trustees and is reported to the Trustees at their next meeting.

      8. BROKERAGE COMMISSIONS. For purposes of this Agreement, brokerage
commissions paid by a Portfolio upon the purchase or sale of its portfolio
securities shall be considered a cost of securities of the Portfolio and shall
be paid by the Portfolio. Idex Management is authorized and directed to place a
Portfolio's securities transactions, or to delegate to Janus Capital the
authority and direction to place a Portfolio's securities transactions, only
with brokers and dealers who render satisfactory service in the execution of
orders at the most favorable prices and at reasonable commission rates;
provided, however, that Idex Management or Janus Capital, may pay a broker or
dealer an amount of commission for effecting


<PAGE>


a securities transaction in excess of the amount of commission another broker or
dealer would have charged for effecting that transaction if Idex Management or
Janus Capital determines in good faith that such amount of commission was
reasonable in relation to the value of the brokerage and research services
provided by such broker or dealer viewed in terms of either that particular
transaction or the overall responsibilities of Idex Management or Janus Capital.
Idex Management and Janus Capital are also authorized to consider sales of
Portfolio shares (which shall be deemed to include also shares of other
registered investment companies with the same investment adviser) by a
broker-dealer or the recommendation of a broker-dealer to its customers that
they purchase Portfolio shares as a factor in selecting broker-dealers to
execute the Portfolio's securities transactions, provided that in placing
portfolio business with such broker-dealers, Idex Management and Janus Capital
shall seek the best execution of each transaction and all such brokerage
placement shall be consistent with the Conduct Rules of the National Association
of Securities Dealers, Inc. Notwithstanding the foregoing, the Fund shall retain
the right to direct the placement of all securities transactions of each
Portfolio, and the Trustees may establish policies or guidelines to be followed
by Idex Management and Janus Capital in placing portfolio transactions for each
Portfolio pursuant to the foregoing provisions. Idex Management shall report on
the placement of portfolio transactions each quarter to the Trustees of the
Fund.

      9. PURCHASES BY AFFILIATES. Neither Idex Management nor any officer or
Director thereof shall take a long or short position in the securities issued by
the Portfolios. This prohibition, however, shall not prevent the purchase from a
Portfolio of shares issued by the Fund on behalf of the Portfolio, by the
officers or Directors of Idex Management (or by deferred benefit plans
established for their benefit) at the current price available to the public, or
at such price with reductions in sales charge as may be permitted by the Fund's
current prospectus, in accordance with Section 22(d) of the 1940 Act.

      10. TERM. This Agreement shall continue in effect, unless sooner
terminated in accordance with its terms, for an initial term of 23 months ending
April 30, 2000, and shall continue in effect from year to year thereafter,
provided such continuance is specifically approved at least annually by the vote
of a majority of the Trustees of the Fund who are not parties hereto or
interested persons (as that term is defined in Section 2(a)(19) of the 1940 Act,
as amended) of any such party, cast in person at a meeting called for the
purpose of voting on the approval of the terms of such renewal, and by either
the Trustees of the Fund or the affirmative vote of a majority of the
outstanding voting securities of each Portfolio (as that phrase is defined in
Section 2(a)(42) of the 1940 Act.

      11. TERMINATION. This Agreement may be terminated at any time, without
penalty, by the Trustees of the Fund, or with respect to a Portfolio, by the
shareholders of such Portfolio acting by vote of at least a majority of its
outstanding voting securities (as that phrase is defined in Section 2(a)(42) of
the 1940 Act),


<PAGE>


provided in either case that 60 days' written notice of termination be given to
Idex Management at its principal place of business. This Agreement may be
terminated by Idex Management at any time by giving 60 days' written notice of
termination to the Fund, addressed to its principal place of business.

      12. USE OF NAME. If this Agreement is terminated and Idex Management no
longer serves as investment adviser to the Portfolios, Idex Management reserves
the right to withdraw from the Fund the use of the name "IDEX" with respect to
the Portfolios or any name misleadingly implying a continuing relationship
between the Portfolios and Idex Management or any of its affiliates.

      13. LIABILITY OF IDEX MANAGEMENT. Idex Management may rely on information
reasonably believed by it to be accurate and reliable. Except as may otherwise
be provided by the 1940 Act, neither Idex Management nor its officers,
directors, employees or agents shall be subject to any liability to the Fund or
the Portfolios or any shareholder of the Portfolios for any error of judgment,
mistake of law or any loss arising out of any investment or other act or
omission in the course of, connected with or arising out of any service to be
rendered hereunder, except by reason of willful misfeasance, bad faith or gross
negligence in its performance of its duties or by reason of reckless disregard
of its obligations and duties under this Agreement.

      14. ASSIGNMENT. This Agreement shall terminate automatically in the event
of any assignment (as the term is defined in Section 2(a)(4) of the 1940 Act) of
this Agreement.

      15. AMENDMENTS. This Agreement may be amended only with the approval by
the affirmative vote of a majority of the outstanding voting securities of each
affected Portfolio (as that phrase is defined in Section 2(a)(42) of the 1940
Act) and the approval by the vote of a majority of Trustees of the Fund who are
not parties hereto or interested persons (as that phrase is defined in Section
2(a)(19) of the 1940 Act) of any such party, cast in person at a meeting called
for the purpose of voting on the approval of such amendment.

      16. PRIOR AGREEMENTS. This Agreement supersedes all prior agreements
between the parties relating to the subject matter hereof, and all such prior
agreements are deemed terminated upon the effectiveness of this Agreement.

      17. LIMITATION OF LIABILITY. A copy of the Fund's Declaration of Trust is
on file with the Secretary of The Commonwealth of Massachusetts, and notice is
hereby given that this Agreement is executed on behalf of the Trustees as
Trustees of the Fund and not individually, and that the obligations under this
Agreement are not binding upon any of the Trustees, officers, shareholders,
agents or employees of the Fund individually, but binding only upon the assets
and property of the Portfolios.

<PAGE>

                                     FORM OF
                                IDEX SERIES FUND

of beneficial interest in the Trust as listed on the attached Schedule A to this
Agreement (each a "Fund," collectively the "Funds").

      The Trust is registered as an open-end investment company registered under
the 1940 Act, and consists of more than one series of shares, including the
Funds. In managing the Funds, as well as in the conduct of certain of its

      (a) to provide a continuous investment program for each Fund including
      advice as to the acquisition, holding or disposition of any or all of the
      securities or other assets which the Funds may own or contemplate
      acquiring from time to time, consistent with the Trust's Declaration of
      Trust and each Fund's investment objective and policies adopted and
      declared by the Board of Trustees and stated in the Funds' current
      Prospectus;

      (b) to cause the officers of Idex Management to attend meetings and
      furnish oral or written reports, as the Trust may reasonably require, in
      order to keep the Trustees and appropriate officers of the Trust fully

<PAGE>


      conditions of the investment securities of the Funds, the investment
      recommendations of Idex Management, and the investment considerations
      which have given rise to those recommendations; and

      (c) to supervise the purchase and sale of securities as directed by the

such Agreement shall be approved by the Board of Trustees, including a majority
of the directors who are not parties to the Sub-Advisory Agreements or
interested persons (within the meaning of Section 2(a)(19) of the 1949 Act) of
any such party (the "Disinterested Directors"), and by the holders of the
outstanding voting securities of each of the Funds in accordance with the
requirements of Section 15 of the 1940 Act, and shall otherwise be subject to,
and contain such provisions as shall be required by, the 1940 Act.

      3. MANAGEMENT AND ADMINISTRATIVE SERVICES. Idex Management shall furnish
or make available to the Funds the services of executive and management

      preparing and filing reports with federal and state regulatory
      authorities; (xi) expenses of shareholders' meetings and of preparing,

      the Trust and Idex Management); (xii) costs of any liability,
      uncollectible items of deposit and other insurance or fidelity bonds;
      (xiii) any costs, expenses or losses arising out of any liability of or
      claim for damage or other relief asserted against the Trust for violation
      of any law; (xiv) expenses of preparing, typesetting and printing
      prospectuses and supplements thereto for existing shareholders and of
      reports and statements to shareholders; (xv) fees and expenses in
      connection with membership in investment company organizations and 12-b1
      fees; and (xvi) any extraordinary expenses incurred by the Trust on behalf
      of the Funds.

      (b) Idex Management shall pay (i) all expenses incurred by it in the
      performance of its duties under this Agreement; and (ii) compensation,
      fees and expenses of officers and Trustees of the Trust, except for such
      Trustees who are not interested persons (as defined in the 1940 Act) of
      Idex Management;

      (c) If, for any fiscal year, the total expenses of a Fund, including but
      not limited to: the fees to Idex Management, compensation to its
      custodian, transfer agent, registrar, auditors and legal counsel, printing
      expense, and fees, compensation and expenses to Trustees who are not
      interested persons, exceed any expense limitation imposed by applicable
      state law, Idex Management shall reimburse a Fund for such excess in the
      manner and to the extent required by applicable state law; provided,
      however, that Idex Management shall reimburse each Fund for the amount of
      such expenses which exceed 1.20% of the Fund's average daily net assets.
      For purposes of this sub-paragraph, "total expenses" shall not include
      interest, taxes, litigation expenses, brokerage commissions or other costs
      incurred in acquiring or disposing of any of a Fund's portfolio
      securities, expenses incurred pursuant to a Fund's Plan of Distribution
      under Rule 12b-1 of the 1940 Act, or any costs arising other than in the
      ordinary and necessary course of a Fund's business.

      5. OBLIGATIONS OF TRUST. The Trust shall have the following obligations
under the Agreement:


<PAGE>


      (a) to keep Idex Management continuously and fully informed as to the
      composition of its investment portfolio of each Fund and the nature of all
      of its assets and liabilities from time to time;

      (b) to furnish Idex Management with a certified copy of any financial
      statement or report prepared for a Fund by certified or independent public
      accountants, and with copies of any financial statements or reports made
      to its shareholders or to any governmental body or securities exchange;

      (c) to furnish Idex Management with any further materials or information
      which Idex Management may reasonably request to enable it to perform its

      provisions of Section 6 hereof.

      6. COMPENSATION. Each Fund shall pay to Idex Management for its services a
fee, computed daily and paid monthly, payable on the last day of each month
during which or part of which this Agreement is in effect, as set forth on
Schedule A attached to this Agreement, as it may be amended from time to time in
accordance with Section 15 below. For the month during which this Agreement
becomes effective and the month during which it terminates, however, there shall
be an appropriate pro-ration of the fee payable for such month based on the
number of calendar days of such month during which this Agreement is effective.

      7. TREATMENT OF INVESTMENT ADVICE. With respect to a Fund, the Fund shall
retain full control over its own investment policies. However, the Trustees of
the Trust may delegate to the appropriate officers of the Trust, or to a
committee of Trustees, the power to authorize purchases, sales or other actions
affecting each Fund in the interim between meetings of the Trustees, provided
such action is consistent with the established investment policy of the Trustees
and is reported to the Trustees at their next meeting.

      8. BROKERAGE COMMISSIONS. For purposes of this Agreement, brokerage
commissions paid by a Fund upon the purchase or sale of its portfolio securities
shall be considered a cost of securities of the Fund and shall be paid by the
Fund. Idex Management is authorized and directed to place a Fund's securities
transactions, or to delegate to each sub-adviser the authority and direction to
place a Fund's securities transactions, only with brokers and dealers who render
satisfactory service in the execution of orders at the most favorable prices and
at reasonable commission rates; provided, however, that Idex Management or each
sub-adviser, may pay a broker or dealer an amount of commission for effecting a
securities transaction in excess of the amount of commission another broker or
dealer would have charged for effecting that transaction if Idex Management or
each sub-adviser determines in good faith that such amount of commission was


<PAGE>


reasonable in relation to the value of the brokerage and research services
provided by such broker or dealer viewed in terms of either that particular
transaction or the overall responsibilities of Idex Management or each
sub-adviser. Idex Management and each sub-adviser are also authorized to
consider sales of Fund shares (which shall be deemed to include also shares of
other registered investment companies with the same investment adviser) by a
broker-dealer or the recommendation of a broker-dealer to its customers that
they purchase Fund shares as a factor in selecting broker-dealers to execute the
Fund's securities transactions, provided that in placing fund business with such
broker-dealers, Idex Management and each sub-adviser shall seek the best
execution of each transaction and all such brokerage placement shall be
consistent with the Conduct Rules of the National Association of Securities
Dealers, Inc. Notwithstanding the foregoing, the Trust shall retain the right to
direct the placement of all securities transactions of each Fund, and the
Trustees may establish policies or guidelines to be followed by Idex Management
and each sub-adviser in placing portfolio transactions for each Fund pursuant to
the foregoing provisions. Idex Management shall report on the placement of
portfolio transactions each quarter to the Trustees of the Trust.

      9. PURCHASES BY AFFILIATES. Neither Idex Management nor any officer or
Director thereof shall take a long or short position in the securities issued by
the Funds. This prohibition, however, shall not prevent the purchase from a Fund
of shares issued by the Fund on behalf of the Trust, by the officers or
Directors of Idex Management (or by deferred benefit plans established for their
benefit) at the current price available to the public, or at such price with
reductions in sales charge as may be permitted by the Fund's current prospectus,
in accordance with Section 22(d) of the 1940 Act.

      10. TERM. This Agreement shall continue in effect, unless sooner
terminated in accordance with its terms, for an initial term ending April 30,
2000, and shall continue in effect from year to year thereafter, provided such
continuance is specifically approved at least annually by the vote of a majority
of the Trustees of the Trust who are not parties hereto or interested persons
(as that term is defined in Section 2(a)(19) of the 1940 Act, as amended) of any
such party, cast in person at a meeting called for the purpose of voting on the
approval of the terms of such renewal, and by either the Trustees of the Trust

                          INVESTMENT COUNSEL AGREEMENT

as amended (the "1940 Act"), between IDEX MANAGEMENT, INC., a Delaware

of the 1940 Act, with IDEX Series Fund, a Massachusetts business trust (referred
to herein as the "Fund") on behalf of the Portfolios listed on the attached
Schedule A to this Agreement (each a "Portfolio," collectively, "Portfolios"),
under which Idex Management has agreed, among other things, to act as investment
adviser to each Portfolio.

      WHEREAS, the Advisory Agreement provides that Idex Management may engage
Janus Capital to furnish investment information and advice to assist Idex
Management in carrying out its responsibilities under the Advisory Agreement as
investment adviser to each Portfolio.

      WHEREAS, it is the purpose of this Agreement to express the mutual
agreements of the parties hereto with respect to the services to be provided by
Janus Capital to Idex Management and the terms and conditions under which such
services will be rendered.

      NOW, THEREFORE, in consideration of the mutual covenants and agreements
set forth herein, the parties hereto agree as follows:

      1. SERVICES OF JANUS CAPITAL. Janus Capital shall act as investment
counsel to Idex Management with respect to each Portfolio. In this capacity,
Janus Capital shall have the following responsibilities:

      (a) provide a continuous investment program for each Portfolio including
          advice as to the acquisition, holding or disposition of any or all of
          the securities or other assets which a Portfolio may own or
          contemplate acquiring from time to time;


<PAGE>


      (b) to cause its officers to attend meetings of Idex Management or the
          Fund and furnish oral or written reports, as Idex Management may
          reasonably require, in order to keep Idex Management and its officers
          and the Trustees of the Fund and appropriate officers of the Fund
          fully informed as to the condition of the investment portfolio of each
          Portfolio, the investment recommendations of Janus Capital, and the
          investment considerations which have given rise to those
          recommendations;

      (c) to furnish such statistical and analytical information and reports as
          may reasonably be required by Idex Management from time to time; and

      (d) to supervise the purchase and sale of securities as directed by the
          appropriate officers of the Fund.

      2. OBLIGATIONS OF IDEX MANAGEMENT. Idex Management shall have the
following obligations under this Agreement:

      (a) to keep Janus Capital continuously and fully informed as to the
          composition of each Portfolio's investment portfolio and the nature of
          each Portfolio's assets and liabilities from time to time;

      (b) to furnish Janus Capital with a certified copy of any financial
          statement or report prepared for each Portfolio by certified or
          independent public accountants, and with copies of any financial
          statements or reports made by a Portfolio to its shareholders or to
          any governmental body or securities exchange;

      (c) to furnish Janus Capital with any further materials or information
          which Janus Capital may reasonably request to enable it to perform its
          functions under this Agreement;

      (d) to compensate Janus Capital for its services under this Agreement by
          the payment of fees as set forth on Schedule A attached to this
          Agreement, as it may be amended from time to time in accordance with
          Section 10 below, less (ii) 50% of any amount reimbursed to the
          Portfolio by Idex Management pursuant to the provisions of Section 4
          (c) of the Advisory Agreement. In the event that this Agreement shall
          be effective for only part of a period to which any such fee received
          by Idex Management is attributable, then an appropriate pro-ration of
          the fee that would have been payable hereunder if this Agreement had
          remained in effect until the end of such period shall be made, based
          on the number of calendar days in such period and the number of
          calendar days during the period in which this 


<PAGE>

          Agreement was in effect. The fees payable to Janus Capital hereunder
          shall be payable upon receipt by Idex Management from the Portfolio of

          Agreement; and

Portfolios. This prohibition, however, shall not prevent the purchase from a
Portfolio of shares issued by the Fund on behalf of the Portfolios by the
officers and Directors of Janus Capital (or deferred benefit plans established
for their benefit) at the current price available to the public, or at such
price with reductions in sales charge as may be permitted in the Fund's current
prospectus in accordance with Section 22(d) of the Investment Company Act of
1940, as amended (the "1940 Act").

      5. LIABILITY OF JANUS CAPITAL. Janus Capital may rely on information
reasonably believed by it to be accurate and reliable. Except as may otherwise
be provided by the 1940 Act, neither Janus Capital nor its officers, directors,
employees or agents shall be subject to any liability to the Fund or any
shareholders of the Fund for any error of judgment, mistake of law or any loss
arising out of any investment or other act or omission in the course of,
connected with or arising out of any service to be rendered hereunder, except by
reason of willful misfeasance, bad faith or gross negligence in the performance
of its duties or by reason of reckless disregard of its obligations and duties
under this Agreement.

continue to be throughout the term of this Agreement, an investment adviser
registered under all applicable federal and state laws. In all matters relating
to the performance of this Agreement, Janus Capital will act in conformity with
the Fund's Declaration of Trust, Bylaws, and current prospectus and with the
instructions and direction of Idex Management and the Fund's Trustees, and will
conform to and comply with the 1940 Act and all other applicable federal or
state laws and regulations.

business, provided that such termination is approved by the Board of Trustees of
the Fund or by vote of a majority of the outstanding voting securities (as that
phrase is defined in Section 2(a)(42) of the 1940 Act) of the affected
Portfolio. This Agreement may 


<PAGE>


be terminated at any time by Janus Capital by giving 60 days' written notice of
such termination to the Fund and Idex Management at their respective principal
places of business.

      8. ASSIGNMENT. This Agreement shall terminate automatically in the event
of any assignment (as that term is defined in Section 2(a)(4) of the 1940 Act)

      9. TERM. This Agreement shall continue in effect, unless sooner terminated
in accordance with its terms, for an initial term of 23 months from the later of
June __, 1998 (closing of Acquisition) and Shareholder approval, and shall
continue in effect from year to year thereafter so long as such continuance is
specifically approved at least annually by the vote of a majority of the
Trustees of the Fund who are not parties hereto or interested persons (as that

terms of such renewal, and by either the Trustees of the Fund or the affirmative
vote of a majority of the outstanding voting securities of the Fund (as that
phrase is defined in Section 2(a)(42) of the 1940 Act).

      10. AMENDMENTS. This Agreement may be amended with respect to a Portfolio
only with the approval by the affirmative vote of a majority of the outstanding

Trustees of the Fund who are not parties hereto or interested persons (as that
term is defined in Section 2(a)(19) of the 1940 Act) of any such party, cast in
person at a meeting called for the purpose of voting on the approval of such
amendment.

      11. PRIOR AGREEMENTS. This agreement supersedes all prior agreements

agreements are deemed terminated upon the effectiveness of this agreement.

      IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of

             manner consistent with the Fund's investment objective, policies,
             and restrictions. In furtherance of this duty, Goldman Sachs, on
             behalf of the Fund, is authorized, in its discretion and without
             prior consultation with IDEX or Idex Management, to:

             (1) Buy, sell, exchange, convert, lend, and otherwise trade in any
             stocks, bonds and other securities or assets; and

             (2) Place orders and negotiate the commissions (if any) for the
             execution of transactions in securities or other assets with or
             through such brokers, dealers, underwriters or issuers as Goldman
             Sachs may select.

(B) ADDITIONAL DUTIES OF SUB-ADVISER. In addition to the above, Sub-Adviser
    shall:

      (a) furnish continuous investment information, advice and recommendations
      to IDEX as to the acquisition, holding or disposition of any or all of the
      securities or other assets which the Fund may own or contemplate acquiring
      from time to time; and

      (b) cause its officers to attend meetings of IDEX and furnish oral or
      written reports, as IDEX may reasonably require, in order to keep IDEX and
      its officers and Board fully informed as to the condition of the
      investment securities of the Fund, the investment recommendations of 
      Goldman Sachs, and the investment considerations which have given rise to 
      those recommendations.

      2. OBLIGATIONS OF IDEX MANAGEMENT. Idex Management shall have the
following obligations under this Agreement:

      (a) to keep Goldman Sachs continuously and fully informed as to the
          composition of the Fund's investment portfolio and the nature of the
          Fund's assets and liabilities from time to time;

      (b) Idex Management to furnish Goldman Sachs with copies of each of the
          following documents and will furnish to Goldman Sachs at its principal
          office all future amendments and supplements to such documents, if
          any, as soon as practicable after such documents become available;

          (1) The Agreement and Declaration of Trust of IDEX, as filed with the
          State of Massachusetts, as in effect on the date hereof and as amended
          from time to time ("Articles");

          (2) The By-Laws of IDEX as in effect on the date hereof and as amended
          from time to time ("By-Laws");

          (3) Certified resolutions of the Board of IDEX authorizing the
          appointment of Idex Management and Goldman Sachs and approving the
          form of the Advisory Agreement and this Agreement;

          (4) IDEX Registration Statement under the 1940 Act and the Securities
          Act of 1933, as amended, on Form N-1A, as filed with the Securities
          and Exchange Commission ("SEC") relating to the Fund and its shares
          and all amendments thereto ("Registration Statement");

          (5) The Notification of Registration of the Fund under the 1940 Act on
          Form N-8A as filed with the SEC and any amendments thereto;

          (6) The Fund's Prospectus (as defined above); and

          (7) A certified copy of any publicly available financial statement or
          report prepared for the Fund by certified or independent public
          accountants, and copies of any financial statements or reports made by
          the Fund to its shareholders or to any government body or securities
          exchange.

      (c) to furnish Goldman Sachs with any further materials or information
      which Goldman Sachs may reasonably request to enable it to perform its
      functions under this Agreement;

      (d) to compensate Goldman Sachs for its services under this Agreement by
      the payment of a monthly fee equal to 0.50% of the average daily net
      assets of the first $50 million in assets, 0.45% of the next $50 - $100
      million in assets and 0.40% of assets in excess of $100 million for the
      Fund. In the event that this Agreement shall be effective for only part of
      a period to which any such fee received by Idex Management is
      attributable, then an appropriate pro-ration of the fee that would have
      been payable hereunder if this Agreement had remained in effect until the
      end of such period shall be made, based on the number of calendar days in
      such period and the number of calendar days during the period in which
      this Agreement was in effect. The fees payable to Goldman Sachs hereunder
      shall be payable upon receipt by Idex Management from the Fund of fees
      payable to Idex Management under Section 6 of the Advisory Agreement;

3.    BROKERAGE.

      A. Goldman Sachs agrees that, in placing orders with broker-dealers for
the purchase or sale of portfolio securities, it shall attempt to obtain quality
execution at favorable security prices (best price and execution); provided
that, on behalf of the Fund, Goldman Sachs may, in its discretion, agree to pay
a broker-dealer that furnishes brokerage or research services as such services
are defined under Section 28(e) of the Securities Exchange Act of 1934, as
amended ("1934 Act"), a higher commission than that which might have been
charged by another broker-dealer for effecting the same transactions, if Goldman
Sachs determines in good faith that such commission is reasonable in relation to
the brokerage and research services provided by the broker-dealer, viewed in
terms of either that particular transaction or the overall responsibilities of
Goldman Sachs with respect to the accounts as to which it exercises investment
discretion (as such term is defined under Section 3(a)(35) of the 1934 Act). In
no instance will portfolio securities be purchased from or sold to Goldman
Sachs, or any affiliated person thereof, except in accordance with the federal
securities laws and the rule and regulations thereunder.

      B. On occasions when Goldman Sachs deems the purchase or sale of a
security to be in the best interest of the Fund as well as other clients of
Goldman Sachs, Goldman Sachs, to the extent permitted by applicable laws and
regulations, may, but shall be under no obligation to, aggregate the securities
to be purchased or sold to attempt to obtain a more favorable price or lower
brokerage commissions and efficient execution. In such event, allocation of the
securities so purchased or sold, as well as the expenses incurred in the
transaction, will be made by Goldman Sachs in the manner Goldman Sachs considers
to be most equitable and consistent with its fiduciary obligations to the Fund
and to its other clients.

C. In addition to the foregoing, Goldman Sachs agrees that orders with
broker-dealers for the purchase or sale of portfolio securities by the Fund
shall be placed in accordance with the standards set forth in the Advisory
Agreement, subject to compliance with applicable laws and procedures adopted by
the Trustees of IDEX.

D. Goldman Sachs is authorized to place orders on behalf of the Fund through the
Goldman Sachs or any affiliate thereof if Goldman Sachs or its affiliate is
registered as a broker or dealer with the SEC or as a FCM with the Commodities
Futures Trading Commission ("CFTC"), to any of its affiliates that are brokers
or dealers or FCBs or such other entities which provide similar services in
foreign countries, or to such brokers or dealers that also provide research or
statistical research and material, or other services to the Funds or Goldman
Sachs. Such allocation shall be in such amounts and proportions as Goldman Sachs
shall determine consistent with the above standards, and, upon, request, Goldman
Sachs will report on said allocation to Idex Management and Board of Trustees of
IDEX, indicating the brokers, dealers or FCBs to which such allocations have
been made and the basis therefor.

      4. TREATMENT OF INVESTMENT ADVICE. Idex Management may direct Goldman
Sachs to furnish its investment information, advice and recommendations directly
to officers of IDEX.

      5. PURCHASES BY AFFILIATES. Neither Goldman Sachs nor any of its officers
or Directors shall take a long or short position in the securities issued by the
Fund. This prohibition, however, shall not prevent the purchase from the Fund of
shares issued by the Fund on behalf of the Fund by the officers and Directors of
Goldman Sachs (or deferred benefit plans established for their benefit) at the
current price available to the public, or at such price with reductions in sales
charge as may be permitted in the Fund's current prospectus in accordance with
Section 22(d) of the Investment Company Act of 1940, as amended (the "1940
Act").

      6. SERVICES TO OTHER CLIENTS. Nothing contained in this Agreement shall
limit or restrict (i) the freedom of Goldman Sachs, or any affiliated person
thereof, to render investment management and corporate administrative services
to other investment companies, to act as investment manager or investment
counselor to other persons, firms, or corporations, or to engage in any other
business activities, or (ii) the right of any director, officer, or employee of
Goldman Sachs, who may also be a trustee, officer, or employee of IDEX, to
engage in any other business or to devote his or her time and attention in part
to the management or other aspects of any other business, whether of a similar
nature or a dissimilar nature.

      7. SUB-ADVISER'S USE OF THE SERVICES OF OTHERS. Goldman Sachs may (at its
cost except as contemplated by paragraph 7 of this Agreement) employ, retain, or
otherwise avail itself of the services or facilities of other persons or
organizations for the purpose of obtaining such statistical and other factual
information, such advice regarding economic factors and trends, such advice as
to occasional transactions in specific securities, or such other information,
advice, or assistance as Goldman Sachs may deem necessary, appropriate, or
convenient for discharge of its obligations hereunder or otherwise helpful to
the Fund, as appropriate, or in the discharge of Goldman Sachs overall
responsibilities with respect to the other accounts that it serves as investment
manager or counselor, provided that Goldman Sachs shall at all times retain
responsibility for making investment recommendations with respect to the Fund.

      8. LIMITATION OF LIABILITY OF THE SUB-ADVISER. Neither Goldman Sachs nor
any of its officers, directors, or employees, nor any person performing
executive, administrative, trading, or other functions for Goldman Sachs, the
Fund (at the direction or request of Goldman Sachs) or the Sub-Adviser in
connection with Goldman Sachs' discharge of its obligations undertaken or
reasonably assumed with respect to this Agreement, shall be liable for any error
of judgment or mistake of law or for any loss suffered by the Company or Fund or
any error of facts or mistake of law contained in any report or date provided by
Goldman Sachs, except for any error, mistake or loss resulting from willful
misfeasance, bad faith or gross negligence in the performance of its duties on
behalf of the Fund or from reckless disregard by Goldman Sachs or any such
person of the duties of Goldman Sachs pursuant to this Agreement.

      9. REPRESENTATIONS. The parties hereto represent, warrant, and agree as

              of an investment company pursuant to Section 9(a) of the 1940 Act
              or otherwise.

         B.   Goldman Sachs has adopted a written code of ethics complying with

              Fund with a copy of such code of ethics, together with evidence of
              its adoption.

         C.   Goldman Sachs has provided Idex Management and IDEX with a copy of
              its Form ADV as most recently filed with the SEC and will,
              promptly after filing any amendment to its Form ADV with the SEC,
              furnish a copy of such amendment to Idex Management.

      10. TERM OF AGREEMENT. This Agreement shall become effective upon the date
first above written, provided that this Agreement shall not take effect unless
it has first been approved (i) by a vote of a majority of those Trustees who are
not parties to this Agreement or interested persons of any such party, cast in
person at a meeting called for the purpose of voting on such approval, and (ii)
by vote of a majority of the Fund's outstanding voting securities. Unless sooner
terminated as provided herein, this Agreement shall continue in effect for an
initial term ending April 30, 2000. Thereafter, this Agreement shall continue in
effect from year to year, with respect to the Fund, subject to the termination
provisions and all other terms and conditions hereof, so long as such
continuation shall be specifically approved at least annually (a) by either the
Board, or by vote of a majority of the outstanding voting securities of the
Fund; and (b) in either event, by the vote, cast in person at a meeting called
for the purpose of voting on such approval, of a majority of the Trustees of
IDEX who are not parties to this Agreement or interested persons of any such
party. Goldman Sachs shall furnish to IDEX, promptly upon its request such
information as may reasonably be necessary to evaluate the terms of this
Agreement or any extension, renewal, or amendment hereof.

      11. TERMINATION OF AGREEMENT. Notwithstanding the foregoing, this
Agreement may be terminated at any time, without the payment of any penalty, by
vote of the Board or by a vote of a majority of the outstanding voting
securities of the Fund on at least 60 days' prior written notice to Goldman
Sachs. This Agreement may also be terminated by Idex Management: (i) on at least
60 days' prior written notice to Goldman Sachs, without the payment of any
penalty; or (ii) if Goldman Sachs becomes unable to discharge its duties and
obligations under this Agreement. Goldman Sachs may terminate this Agreement at
any time, or preclude its renewal without the payment of any penalty, on at
least 60 days' prior notice to Idex Management. This Agreement shall terminate
automatically in the event of its assignment or upon termination of the Advisory
Agreement.

      12. AMENDMENT OF AGREEMENT. No provision of this Agreement may be changed,
waived, discharged, or terminated orally, but only by an instrument in writing
signed by the party against which enforcement of the change, waiver, discharge,
or termination is sought, and no amendment of this Agreement shall be effective
until approved by vote or a majority of the Fund outstanding voting securities
and a vote of a majority of those Trustees of IDEX who are no parties to this
Agreement or interested persons of any such party, cast in person at a meeting
called for the purpose of voting on such amendment, unless otherwise permitted
in accordance with the 1940 Act.

      13. MISCELLANEOUS.

         A. GOVERNING LAW. This Agreement shall be construed in accordance with
the laws of the State of New York without giving effect to the conflicts of laws
principles thereof, and the 1940 Act. To the extent that the applicable laws of
the State of New York conflict with the applicable provisions of the 1940 Act,
the latter shall control.

         B. CAPTIONS. The captions contained in this Agreement are included for
convenience of reference only and in no way define or delimit any of the
provisions hereof or otherwise affect their construction or effect.

         C. ENTIRE AGREEMENT. This Agreement represents the entire agreement and
understanding of the parties hereto and shall supersede any prior agreements
between the parties relating to the subject matter hereof, and all such prior
agreements shall be deemed terminated upon the effectiveness of this Agreement.

         D. INTERPRETATION. Nothing herein contained shall be deemed to require
IDEX to take any action contrary to its Articles or By-Laws, or any applicable
statutory or regulatory requirement to which it is subject or by which it is
bound, or to relieve or deprive the Board of its responsibility for and control
of the conduct of the affairs of IDEX.

         E. DEFINITIONS. Any question of interpretation of any term or provision
of this Agreement having a counterpart in or otherwise derived from a term or
provision of the 1940 Act shall be resolved by reference to such term or
provision of the 1940 Act and to interpretation thereof, if any, by the United
States courts or, in the absence of any controlling decision of any such court,
by rules, regulations, or orders of the SEC validly issued pursuant to the 1940
Act. As used in this Agreement, the terms "majority of the outstanding voting
securities," "affiliated person," "interested person," "assignment," "broker,"
"investment adviser," "net assets," "sale," "sell," and "security" shall have
the same meaning as such terms have in the 1940 Act, subject to such exemption
as may be granted by the SEC by any rule, regulation, or order. Where the effect
of a requirement of the federal securities laws reflected in any provision of
this Agreement is made less restrictive by a rule, regulation, or order of the
SEC, whether of special or general application, such provision shall be deemed
to incorporate the effect of such rule, regulation, or order, unless Idex
Management and Goldman Sachs agree to the contrary.

      14. COMPLIANCE WITH LAWS.

      (a) In all matters relating to the performance of this Agreement, Goldman
          Sachs will act in conformity with the IDEX Declaration of Trust, 
          Bylaws, and current prospectus and with the instructions and direction
          of Idex Management and the Fund's Trustees.

      (b) Goldman Sachs shall conform with (1) the 1940 Act and all rules and
          regulations thereunder, and releases and interpretations thereto
          (including any no-action letters and exemptive orders which have been
          granted by the SEC to the Fund, Idex Management and/or Goldman Sachs
          and (2) with all other applicable federal and state laws and
          regulations pertaining to management of investment companies.

      (c) Idex Management shall perform quarterly and annual tax compliance
          tests to ensure that the Fund is in compliance with Subchapter M of
          the Internal Revenue Code ("IRC"). In connection with such compliance
          tests, Idex Management shall prepare and provide reports to Goldman
          Sachs within 10 business days of a calendar quarter end relating to
          the diversification of the Fund under Subchapter M. Goldman Sachs
          shall review such reports for purposes of determining compliance with
          such diversification requirements. If it is determined that the Fund
          is not in compliance with the requirements noted above, Goldman Sachs,
          in consultation with Idex Management, will take prompt action to bring
          the Fund back into compliance within the time permitted under the IRC.

      15. ASSIGNMENT. This Agreement shall terminate automatically in the event
of any assignment (as that term is defined in Section 2(a)(4) of the 1940 Act)
of this Agreement.

      16. REFERENCE TO SUB-ADVISER. Neither Idex Management nor IDEX will
publish or distribute any information, including but not limited to registration
statements, advertising or promotional material, regarding the provision of
investment advisory services by Goldman Sachs pursuant to this Agreement, or use
in advertising, publicity or otherwise the name of Goldman Sachs or any of its
affiliates, or any trade name, trademark, trade device, service mark, symbol or
any abbreviation, contraction or simulation thereof of Goldman Sachs or its
affiliates, without the prior written consent of Goldman Sachs. Notwithstanding
the foregoing, Idex Management may distribute information regarding the
provision of investment advisory services by Goldman Sachs to the Fund's Board
of Trustees ("Board Materials") without the prior written consent of Goldman
Sachs. Idex Management will provide copies of the Board Materials to Goldman
Sachs within a reasonable time following distribution to the IDEX Board of
Trustees.

      IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date first above written.

          be effective for only part of a period to which any such fee received
          by Idex Management is attributable, then an appropriate pro-ration of
          the fee that would have been payable hereunder if this Agreement had
          remained in effect until the end of such period shall be made, based
          on the number of calendar days in such period and the number of
          calendar days during the period in which this Agreement was in effect.

      3. TREATMENT OF INVESTMENT ADVICE. Idex Management may direct T. Rowe to
furnish its investment information, advice and recommendations directly to
officers of IDEX.

      4. PURCHASES BY AFFILIATES. Neither T. Rowe nor any of its officers or
Directors shall take a long or short position in the securities issued by the
Funds on terms not otherwise available to the public. This prohibition, however,
shall not prevent the purchase from a Fund of shares issued by the Fund on
behalf of the Funds by the officers and Directors of T. Rowe (or deferred
benefit plans established for their benefit) at the current price available to
the public, or at such price with reductions in sales charge as may be permitted
in the Fund's current prospectus in accordance with Section 22(d) of the
Investment Company Act of 1940, as amended (the "1940 Act").

      5. SERVICE OF OTHER CLIENTS. Nothing contained in this Agreement shall
limit or restrict (i) the freedom of T. Rowe, or any affiliated person thereof,
to render investment management and corporate administrative services to other
investment companies, to act as investment manager or investment counselor to
other persons, firms, or corporations, or to engage in any other business
activities, or (ii) the right of any director, officer, or employee of T. Rowe,
who may also be a trustee, officer, or employee of IDEX, to engage in any other
business or to devote his or her time and attention in part to the management or
other aspects of any other business, whether of a similar nature or a dissimilar
nature.

      6. T. ROWE'S USE OF THE SERVICES OF OTHERS. T. Rowe may (at its cost
except as contemplated by Paragraph 5 of this Agreement) employ, retain, or
otherwise avail itself of the services or facilities of other persons or
organizations for the purpose of obtaining such statistical and other factual
information, such advice regarding economic factors and trends, such advice as
to occasional transactions in specific securities, or such other information,
advice, or assistance as T. Rowe may deem necessary, appropriate, or convenient
for the discharge of its obligations hereunder or otherwise helpful to the
Funds, as appropriate, or in the discharge of T. Rowe's overall responsibilities
with respect to the other accounts that it serves as investment manager or
counselor, provided that T. Rowe shall at all times retain responsibility for
making investment recommendations with respect to each Fund.

      7. LIMITATION OF LIABILITY OF T. ROWE. T. Rowe may rely on information
reasonably believed by it to be accurate and reliable. Except as may otherwise
be provided by the 1940 Act, neither T. Rowe nor its officers, directors,
employees or agents shall be subject to any liability to the Funds or any
shareholders of the Funds for any error of judgment, mistake of law or any loss
arising out of any investment or other act or omission in the course of,
connected with or arising out of any service to be rendered hereunder, except by
reason of willful misfeasance, bad faith or gross negligence in the performance
of its duties or by reason of reckless disregard of its obligations and duties
under this Agreement.

      8. COMPLIANCE WITH LAWS. T. Rowe represents that it is, and will continue
to be throughout the term of this Agreement,
<PAGE>
an investment adviser registered under all applicable federal and state laws. In
all matters relating to the performance of this Agreement, T. Rowe will act in
conformity with the IDEX Declaration of Trust, Bylaws, and current prospectus
and with the reasonable instructions and direction of Idex Management and IDEX's
Trustees regarding management of the Funds' investments and will conform to and
comply with the 1940 Act and all other applicable federal or state laws and
regulations.

      9.    BROKERAGE.

            A. T. Rowe agrees that, in placing orders with broker-dealers for
the purchase or sale of each Fund's securities, it shall attempt to obtain
quality execution at favorable security prices (best price and execution);
provided that, on behalf of the Fund, the T. Rowe may, in its discretion, agree
to pay a broker-dealer that furnishes brokerage or research services as such
services are defined under Section 28(e) of the Securities Exchange Act of 1934,
as amended ("1934 Act"), a higher commission than that which might have been
charged by another broker-dealer for effecting the same transactions, if T. Rowe
determines in good faith that such commission is reasonable in relation to the
brokerage and research services provided by the broker-dealer, viewed in terms
of either that particular transaction or the overall responsibilities of T. Rowe
with respect to the accounts as to which it exercises investment discretion (as
such term is defined under Section 3(a)(35) of the 1934 Act). In no instance
will Fund securities be purchased from or sold to T. Rowe, or any affiliated
person thereof, except in accordance with the federal securities laws and the
rules and regulations thereunder.

            B. On occasions when T. Rowe deems the purchase or sale of a
security to be in the best interest of the Funds as well as other clients of T.
Rowe, T. Rowe, to the extent permitted by applicable laws and regulations, may,
but shall be under no obligation to, aggregate the securities to be purchased or
sold to attempt to obtain a more favorable price or lower brokerage commissions
and efficient execution. In such event, allocation of the securities so
purchased or sold, as well as the expenses incurred in the transaction, will be
made by T. Rowe in the manner T. Rowe considers to be the most equitable and
consistent with its fiduciary obligations to the Funds and to its other clients,
subject to compliance with applicable laws and procedures adopted by the
Trustees of IDEX.

      10. TERMINATION. This Agreement shall terminate automatically with respect
to a Fund upon the termination of the Advisory Agreement with respect to such
Fund. This Agreement may be terminated at any time with respect to a Fund,
without penalty, by Idex Management or by IDEX by giving 60 days' written notice
of such termination to T. Rowe at its principal place of business, provided
that, if terminated by IDEX, such termination is approved by the Board of
Trustees of IDEX or by vote of a majority of the outstanding voting securities
(as that phrase is defined in Section 2(a)(42) of the 1940 Act) of the affected
Fund. This Agreement may be terminated at any time by T. Rowe by giving 60 days'
written notice of such termination to IDEX and Idex Management at their
respective principal places of business.

      11. ASSIGNMENT. This Agreement shall terminate automatically, with respect
to a Fund, in the event of any assignment (as that term is defined in Section
2(a)(4) of the 1940 Act) of this Agreement with respect to a Fund.

      12. TERM. This Agreement shall continue in effect, with respect to a Fund,
unless sooner terminated in accordance with its terms, for an initial term
ending April 30, 2000, and shall continue in effect from year to year thereafter
so long as such continuance is specifically approved at least annually by the
vote of a majority of the Trustees of IDEX who are not parties hereto or
interested persons (as that term is defined in Section 2(a)(19) of the 1940 Act)
of any such party, cast in person at a meeting called for the purpose of voting
on the approval of the terms of such renewal, and by either the Trustees of IDEX
or the affirmative vote of a majority of the outstanding voting securities of
the Funds (as that phrase is defined in Section 2(a)(42) of the 1940 Act).

      13. AMENDMENTS. This Agreement may be amended with respect to a Fund only
with the approval by the affirmative vote of a majority of the outstanding
voting securities (as that phrase is defined in Section 2(a)(42) of the 1940
Act) of such Fund and the approval by the vote of a majority of the Trustees of
IDEX who are not parties hereto or interested persons (as that term is defined
in Section 2(a)(19) of the 1940 Act) of any such party, cast in person at a
meeting called for the purpose of voting on the approval of such amendment,
unless otherwise permitted in accordance with the 1940 Act.

      14. PRIOR AGREEMENTS. This agreement supersedes all prior agreements
between the parties relating to the subject matter hereof, and all such prior
agreements are deemed terminated upon the effectiveness of this agreement.

      15.  MISCELLANEOUS.

      A. GOVERNING LAW. This Agreement shall be construed in accordance with the
laws of the State of Maryland without giving effect to the conflicts of laws
principles thereof, and the 1940 Act. To the extent that the applicable laws of
the State of Maryland conflict with the applicable provisions of the 1940 Act,
the latter shall control.
<PAGE>


      B. CAPTIONS. The captions contained in this Agreement are included for
convenience of reference only and in no way define or delimit any of the
provisions hereof or otherwise affect their construction or effect.

      C. INTERPRETATION. Nothing herein contained shall be deemed to require
IDEX to take any action contrary to its Articles or By-Laws, or any applicable
statutory or regulatory requirement to which it is subject or by which it is
bound, or to relieve or deprive the Board of its responsibility for and control
of the conduct of the affairs of IDEX.

      D. DEFINITIONS. Any question of interpretation of any term or provision of
this Agreement having a counterpart in or otherwise derived from a term or
provision of the 1940 Act shall be resolved by reference to such term or
provision of the 1940 Act and to interpretations thereof, if any, by the United
States courts or, in the absence of any controlling decision of any such court,
by rules, regulations, or orders of the SEC validly issued pursuant to the 1940
Act. As used in this Agreement, the terms "majority of the outstanding voting
securities," "affiliated person," "interested person," "assignment," "broker,"
"investment adviser," "net assets," "sale," "sell," and "security" shall have
the same meaning as such terms have in the 1940 Act, subject to such exemption
as may be granted by the SEC by any rule, regulation, or order. Where the effect
of a requirement of the federal securities laws reflected in any provision of
this Agreement is made less restrictive by a rule, regulation, or order of the
SEC, whether of special or general application, such provision shall be deemed
to incorporate the effect of such rule, regulation, or order, unless Idex
Management, Inc. and T. Rowe agree to the contrary.

      IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date first above written.

<PAGE>


                         FORM OF SUB-ADVISORY AGREEMENT

      Agreement dated and effective as of March 1, 1999, between IDEX
Management, Inc., a Delaware corporation (the "Adviser") and Salomon Brothers
Asset Management, Inc., a Delaware corporation (the "Sub-Adviser").

      WHEREAS, the Adviser has entered into an Advisory Agreement (the "Advisory
Agreement") dated March 1, 1999, with IDEX Series Fund ("IDEX"), a Massachusetts
business trust registered as an open-end, management investment company under
the Investment Company Act of 1940, as amended (the "1940 Act"), on behalf of
the Mid-Cap Opportunities Fund (the "Fund") of IDEX pursuant to which the
Adviser provides investment advisory services to the Fund;

      WHEREAS, the Adviser has the authority to delegate its investment advisory
responsibilities under the Advisory Agreement to one or more sub-advisers;

      WHEREAS,  the  Adviser  desires  to retain  the  Sub-Adviser  to provide
investment advisory services to the Fund;

      NOW THEREFORE, in consideration of the mutual agreements herein made, the
Adviser and the Sub-Adviser agree as follows:

      1. (a) The Adviser employs the Sub-Adviser, subject to the direction and
control of the trustees of IDEX, including without limitation any approval of
the trustees of IDEX required by the 1940 Act, to (a) make, in consultation with
the Adviser and the IDEX Board of Trustees, investment strategy decisions for
the Fund, (b) manage the investing and reinvesting of the Fund's assets and (c)
place purchase and sale orders on behalf of the Fund. The Sub-Adviser shall have
the sole ultimate discretion over investment decisions for the Fund.

         (b)  At the Adviser's request, the Sub-Adviser agrees:

              (1) to cause its officers to attend meetings of IDEX and furnish
                  oral or written reports, as the Adviser may reasonably
                  require, in order to keep the Adviser and its officers and the
                  Trustees of IDEX and appropriate officers of IDEX fully
                  informed as to the condition of the investments of the Fund
                  and the investment considerations which have given rise to
                  those recommendations; and

              (2) to furnish such statistical and analytical information and
                  reports as may reasonably be required by the Adviser from time
                  to time.

      2. (a) The adviser shall provide (or cause the Fund's custodian to
provide) timely information to the Sub-Adviser regarding such matters as the
composition of assets in the Fund, cash requirements and cash available for
investment in the Fund, and all other information as may be reasonably necessary
for the Sub-Adviser to perform its responsibilities hereunder.

         (b) The Adviser agrees to furnish the Sub-Adviser with minutes of
meetings of the Board of Trustees of IDEX applicable to the Fund to the extent
they may affect the duties of the Sub-Adviser, and with copies of any financial
statements or reports made by the Fund to its shareholders, and any further
materials or


<PAGE>


information which the Sub-Adviser may reasonably request to enable it to perform
its functions under this Agreement.

      3. (a) The Sub-Adviser shall, at its expense, provide office space, office
facilities and personnel reasonably necessary for performance of the services to
be provided by the Sub-Adviser pursuant to this Agreement.

         (b) Except as provided in subparagraph 3(a) hereof, the Fund shall be
responsible for all of the Fund's expenses and liabilities, including
organizational and offering expenses (which include out-of-pocket expenses, but
not overhead or employee costs of the Sub-Adviser); expenses for legal,
accounting and auditing services; taxes and governmental fees; dues and expenses
incurred in connection with membership in investment company organizations;
costs of printing and distributing shareholder reports, proxy materials,
prospectuses, stock certificates and distribution of dividends; charges of the
Fund's custodians and sub-custodians, administrators and sub-administrators,
registrars, transfer agents, dividend disbursing agents and dividend
reinvestment plan agents; payment for portfolio pricing services to a pricing
agent, if any; registration and filing fees of the Securities and Exchange
Commission (the "SEC"); expenses of registering or qualifying securities of the
Fund for sale in the various states; freight and other charges in connection
with the shipment of the Fund's portfolio securities; fees and expenses of
non-interested trustees; travel expenses or an appropriate portion thereof of
trustees and offcers of the Fund who are trustees, officers or employees of the
Sub-Adviser to the extent that such expenses relate to attendance at meetings of
the Board of Trustees or any committee thereof; salaries of shareholder
relations personnel; costs of shareholders meetings; insurance; interest;
brokerage costs; and litigation and other extraordinary or non-recurring
expenses.

      4. The Sub-Adviser shall make investments for the Fund's account in
accordance with the investment objectives, policies and limitations set forth in
IDEX's Agreement and Declaration of Trust as amended from time to time (the
"Declaration of Trust), the Registration Statement, as in effect from time to
time (the "Registration Statement"), filed with the SEC by IDEX under the 1940
Act and the Securities Act of 1933, as amended, the provisions of the Internal
Revenue Code of 1986, as amended, and supplemented from time to time, relating
to regulated investment companies, and policy decisions adopted by the IDEX
Board of Trustees from time to time. Copies of any amendments to the documents
referred to in the preceding sentence shall be promptly furnished to the
Sub-Adviser. The Sub-Adviser shall advise the IDEX officers and Board of
Trustees, at such time as the IDEX Board of Trustees may specify, of investments
made for the Fund's account and shall, when requested by the IDEX officers or
Board of Trustees, supply the reasons for making such investments.

      5. Subject to applicable laws, the Sub-Adviser may contract with or
consult with such banks, other securities firms, brokers or other parties,
without additional expense to the Fund, as it may deem appropriate regarding
investment advice, research and statistical data, clerical assistance or
otherwise.

      6. Subject to applicable laws, the Sub-Adviser is authorized on behalf of
the Fund, from time to time when deemed to be in the best interests of the Fund
and to the extent permitted by applicable law, to purchase and/or sell
securities in which the Sub-Adviser or any of their affiliates underwrites,
deals in and/or makes a market and/or may perform or seek to perform investment
banking services for issuers of such securities. The Sub-Adviser is further
authorized, to the extent permitted by applicable law, to select brokers
(including Salomon Brothers Inc or any other brokers affiliated with the
Sub-Adviser) for the execution of trades for the Fund.

      7. Consistent with the Sub-Adviser's duty to seek to obtain quality
execution at favorable security prices (best price and execution) the
Sub-Adviser is authorized, for the purchase and sale of the Fund's portfolio


<PAGE>


securities, to employ such dealers and brokers as may, in the judgment of the
Sub-Adviser, implement the policy of the Fund to obtain the best results taking
into account such factors as price, including dealer spread, the size, type and
difficulty of the transaction involved, the firm's general execution and
operational facilities and the firm's risk in positioning the securities
involved. Consistent with this policy, the Sub-Adviser is authorized to direct
the execution of the Fund's portfolio transactions to dealers and brokers
furnishing statistical information or research, as such is defined in Section
28(e) of the Securities Exchange Act of 1934, deemed by the Sub-Adviser to be
useful or valuable to the performance of its investment advisory functions for
the Fund. Information so received will be in addition to and not in lieu of the
services required to be performed by the Sub-Adviser. It is understood that the
expenses of the Sub-Adviser will not necessarily be reduced as a result of the
receipt of such information or research. The Sub-Adviser may use for the benefit
of the Sub-Adviser's other clients, or make available to companies affiliated
with the Sub-Adviser or to its directors for the benefit of its clients, any
such information or research services that the Sub-Adviser received from brokers
or dealers.

      8. To compensate the Sub-Adviser for its services provided, and the
expenses assumed under this Agreement, by (i) the payment of a monthly fee as
set forth on Schedule A attached to this Agreement, as it may be amended from
time to time in accordance with Section 11 below. If the fee payable to the
Sub-Adviser pursuant to this paragraph 8 begins to accrue before the end of any
month or if this Agreement terminates before the end of any month, the fee for
the period from such date to the end of such month or from the beginning of such
month to the date of termination, as the case may be, shall be prorated
according to the proportion which such period bears to the full month in which
such effectiveness or termination occurs. For purposes of calculating each such
monthly fee, the value of the Fund's net assets shall be computed at the time
and in the manner specified in the Registration Statement.

      9. The Sub-Adviser represents and warrants that it is duly registered and
authorized as an investment adviser under the Investment Adviser Act of 1940, as
amended, and any applicable state laws, and the Sub-Adviser agrees to maintain
effective all requisite registations, authorizations and licenses, as the case
may be, until termination of this Agreement.

      10. The Sub-Adviser shall exercise its best judgment in rendering the
services in accordance with the terms of this Agreement. The Sub-Adviser shall
not be liable for any error of judgment or mistake of law or for any act or
omission or any loss suffered by the Fund in connection with the matters to
which this Agreement relates, provided that nothing herein shall be deemed to
protect or purport to protect the Sub-Adviser against any liability to the Fund
or its shareholders, or the Adviser, to which the Sub-Adviser would otherwise be
subject by reason of willful misfeasance, bad faith or gross negligence on its
part in the performance of its duties or from reckless disregard by it of its
obligations and duties under this Agreement ("disabling conduct").

      11. This Agreement may be amended with respect to the Fund only with the
approval by the affirmative vote of a majority of the outstanding voting
securities (as that phrase is defined in Section 2(a)(42) of the 1940 Act) of
the Fund and the approval by the vote of a majority of the Trustees of IDEX,
including a majority of Trustees who are not parties hereto or interested
persons (as that term is defined in Section 2(a)(19) of the 1940 Act) of any
such party, cast in person at a meeting called for the purpose of voting on the
approval of such amendment, unless otherwise permitted in accordance with the
1940 Act.

      12. This Agreement shall become effective as of the date of its execution
and continue in effect for an initial term ending April 30, 2000, and thereafter
for successive annual periods, provided that such continuance is specifically
approved at least annually (a) by the vote of a majority of IDEX's outstanding
voting securities (as defined in the 1940 Act) or by the IDEX Board of Trustees
and (b) by the vote, cast in person at a meeting called for the purpose, of a
majority of the IDEX Trustees who are not parties to this Agreement or
"interested 


<PAGE>


persons" (as defined in the 1940 Act) of any such party. This Agreement may be
terminated at any time, without the payment of any penalty, by (i) IDEX, or by a
vote of the majority of IDEX's entire Board of Trustees on 60 days' written
notice to the Sub-Adviser or (ii) by the Sub-Adviser on 60 days' written notice
to the Adviser or (iii) by the Adviser on 60 days' written notice to the
Sub-Adviser. This Agreement shall terminate automatically in the event of its
assignment (as defined in the 1940 Act).

      13. Nothing herein shall be deemed to limit or restrict the right of the
Sub-Adviser, or any affiliate of the Sub-Adviser, or any employee of the
Sub-Adviser, to engage in any other business or to devote time and attention to
the management or other aspects of any other business, whether of a similar or
dissimilar nature, or to render services of any kind to any other corporation,
firm, individual or association. Nothing herein shall be construed as
constituting the Sub-Adviser an agent of the Adviser or the Fund.

      14. This Agreement shall be governed by the laws of the State of New York;
provided, however, that nothing herein shall be construed as being inconsistent
with the 1940 Act.

                                     FORM OF
                                IDEX SERIES FUND
                          INVESTMENT COUNSEL AGREEMENT

      This Agreement is entered into as of March 1, 1999 between IDEX
MANAGEMENT, INC., a Delaware corporation (referred to herein as "Idex
Management"), and Pilgrim Baxter and Associates, Ltd. a Delaware corporation
(referred to herein as "Pilgrim Baxter").

      WHEREAS, Idex Management entered into a Management and Investment Advisory
Agreement (referred to herein as the "Advisory Agreement"), dated as of March 1,
1999 with IDEX Series Fund, a Massachusetts business trust (referred to herein
as "IDEX"), an open-end management investment company registered under The
Investment Company Act of 1940 (the "1940 Act"), on behalf of the Mid-Cap Summit
Fund (the "Fund"), under which Idex Management has agreed, among other things,
to act as investment adviser to the Fund.

      WHEREAS, the Advisory Agreement provides that Idex Management may engage
Pilgrim Baxter to furnish investment information and advice to assist Idex
Management in carrying out its responsibilities under the Advisory Agreement as
investment adviser to the Fund.

      WHEREAS, it is the purpose of this Agreement to express the mutual
agreements of the parties hereto with respect to the services to be provided by
Pilgrim Baxter to Idex Management and the terms and conditions under which such
services will be rendered.

      NOW, THEREFORE, in consideration of the mutual covenants and agreements
set forth herein, the parties hereto agree as follows:

      1. SERVICES OF PILGRIM BAXTER. Pilgrim Baxter shall act as investment
adviser to Idex Management with respect to the Fund. In this capacity, Pilgrim
Baxter shall have the following responsibilities:

      (a) to provide a continuous investment program for the Fund including
          management of the acquisition, holding or disposition of any or all of
          the securities or other assets which the Fund may own or contemplate
          acquiring from time to time;

      (b) Pilgrim Baxter will place orders for the purchase and sale of
          securities primarily with or through such persons, brokers or dealers
          whom it believes will provide the most favorable price and efficient
          execution. Within the framework of this policy and in accordance with
          Section 28(e) of the Securities & Exchange Act of 1934, Pilgrim Baxter
          may consider the financial responsibility, research and investment
          information and other services provided by brokers or dealers who may
          effect or be a party to any such transaction or other transactions to
          which Pilgrim Baxter's other clients may be a party. It is understood
          that it is desirable for the Fund that Pilgrim Baxter have access to
          supplemental investment and market research and security and economic
          analysis provided by brokers who may execute brokerage transactions at
          a higher cost to the Fund that may result when allocating brokerage to
          other brokers solely on the basis of seeking the most favorable price.
          Therefore, Pilgrim Baxter is authorized to place orders for the
          purchase and sale of securities for the Fund with such brokers,
          subject to review by Idex Management and the Trust's Board of
          Trustees, from time to time, with respect to the extent and
          continuation of this practice. It is understood that the services
          provided by such brokers also may be useful to Pilgrim Baxter in
          connection with Pilgrim Baxter's services to other clients.

          On occasions when Pilgrim Baxter deems the purchase or sale of a
          security to be in the best interest of the Fund as well as other
          clients of Pilgrim Baxter, to the extent permitted by applicable laws
          and regulations, Pilgrim Baxter may, but shall be under no obligation
          to, aggregate the securities to be so purchased or sold in order to
          obtain the most favorable price or lower brokerage commissions and
          efficient execution. In such event, allocation of the securities so
          purchased or sold, as well as the expenses incurred in the
          transaction, will be made by Pilgrim Baxter in the manner it considers
          to be the most equitable and consistent with its fiduciary obligations
          to the Fund and to such other clients.

      (c) to cause its officers to attend meetings of Idex Management or the
          Fund and furnish oral or written reports, as Idex Management may
          reasonably require, in order to keep Idex Management and its officers
          and the Trustees of IDEX and appropriate officers of IDEX fully
          informed as to the condition of the investment portfolio of the Fund,
          the investment recommendations of Pilgrim Baxter, and the investment
          considerations which have given rise to those recommendations;

      (d) to furnish such statistical and analytical information and reports as
          may reasonably be required by Idex Management


<PAGE>

          from time to time; and

      (e) to supervise the purchase and sale of securities.

      2. OBLIGATIONS OF IDEX MANAGEMENT. Idex Management shall have the
following obligations under this Agreement:

      (a) to keep Pilgrim Baxter continuously and fully informed as to the
          composition of the Fund's investment portfolio and the nature of the
          Fund's assets and liabilities from time to time;

      (b) to furnish Pilgrim Baxter with a certified copy of the IDEX's By-laws
          and with a certified copy of any financial statement or report
          prepared for the Fund by certified or independent public accountants,
          and with copies of any financial statements or reports made by the
          Fund to its shareholders or to any governmental body or securities
          exchange;

      (c) to promptly furnish Pilgrim Baxter with copies of the Fund's current
          prospectus and statement of additional information, together with any
          investment restrictions or limitations imposed upon the management of
          the assets of the Fund by the Trust's Board of Trustees or officers,
          or those imposed by Idex Management, and copies of any or all
          Exemptive Orders or no-action letters received by the Trust from the
          Securities and Exchange Commission which may apply to the Fund.

      (d) to furnish Pilgrim Baxter with any further materials or information
          which Pilgrim Baxter may reasonably request to enable it to perform
          its functions under this Agreement;

      (e) to compensate Pilgrim Baxter for its services provided, and the
          expenses assumed under this Agreement, by (i) the payment of a monthly
          fee as set forth on schedule A attached to this Agreement, as it may
          be amended from time to time in accordance with Section 10 below. In
          the event that this Agreement shall be effective for only part of a
          period to which any such fee received by Idex Management is
          attributable, then an appropriate pro-ration of the fee that would
          have been payable hereunder if this Agreement had remained in effect
          until the end of such period shall be made, based on the number of
          calendar days in such period and the number of calendar days during
          the period in which this Agreement was in effect. The fees payable to
          Pilgrim Baxter hereunder shall be payable upon receipt by Idex
          Management from the Fund of fees payable to Idex Management under
          Section 6 of the Advisory Agreement; and

      3. TREATMENT OF INVESTMENT ADVICE. Idex Management may direct Pilgrim
Baxter to furnish its investment information, advice and recommendations
directly to officers of IDEX.

      4. PURCHASES BY AFFILIATES. Neither Pilgrim Baxter nor any of its officers
or Directors shall take a long or short position in the securities issued by the
Fund. This prohibition, however, shall not prevent the purchase from the Fund of
shares issued by the Fund on behalf of the Fund by the officers and Directors of
Pilgrim Baxter (or deferred benefit plans established for their benefit) at the
current price available to the public, or at such price with reductions in sales
charge as may be permitted in the Fund's current prospectus in accordance with
Section 22(d) of the Investment Company Act of 1940, as amended (the "1940
Act").

      5. LIABILITY OF PILGRIM BAXTER. Pilgrim Baxter may rely on information
provided to it by Idex Management or IDEX reasonably believed by it to be
accurate and reliable. Except as may otherwise be provided by the 1940 Act,
neither Pilgrim Baxter nor its officers, directors, employees or agents shall be
subject to any liability to the Fund or any shareholders of the Fund or to Idex
Management for any error of judgment, mistake of law or any loss arising out of
any investment or other act or omission in the course of, connected with or
arising out of any service to be rendered hereunder, except by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties or
by reason of reckless disregard of its obligations and duties under this
Agreement.

      6. COMPLIANCE WITH LAWS. Pilgrim Baxter represents that it is, and will
continue to be throughout the term of this Agreement, an investment adviser
registered under all applicable federal and state laws. In all matters relating
to the performance of this Agreement, Pilgrim Baxter will act in conformity with
the IDEX's Declaration of Trust, Bylaws, and current prospectus and with the
instructions and direction of Idex Management and IDEX's Trustees, and will
conform to and comply with the 1940 Act and all other applicable federal or
state laws and regulations.

      7. TERMINATION. This Agreement shall terminate automatically with respect
to the Fund upon the termination of the Advisory Agreement with respect to such
Fund. This Agreement may be terminated at any time with respect to the Fund,
without penalty, by Idex Management or by IDEX by giving 60 days' written notice
of such termination to Pilgrim Baxter at its principal place of business,
provided that, if terminated by IDEX, such termination is approved by the Board
of Trustees of IDEX or by vote of a majority of the outstanding voting
securities (as that phrase is defined in Section 2(a)(42) of the 1940 Act) of
the Fund. This Agreement may be terminated at any time by Pilgrim Baxter by
giving 60 days' written notice of such termination to IDEX and Idex Management
at their respective principal places of business.

of any assignment (as that term is defined in Section 2(a)(4) of the 1940 Act)
of this Agreement.

      9. TERM. This Agreement shall continue in effect, unless sooner terminated
in accordance with its terms, for an initial term ending April 30, 2000, and
shall continue in effect from year to year thereafter so long as such
continuance is specifically approved at least annually by the vote of a majority
of the Trustees of IDEX who are not parties hereto or interested persons (as
that term is defined in Section 2(a)(19) of the 1940 Act) of any such party,
cast in person at a meeting called for the purpose of voting on the approval of
the terms of such renewal, and by either the Trustees of IDEX or the affirmative
vote of a majority of the outstanding voting securities of the Fund (as that
phrase is defined in Section 2(a)(42) of the 1940 Act).

      10. AMENDMENTS. This Agreement may be amended with respect to the Fund
only with the approval by the affirmative vote of a majority of the outstanding
voting securities (as that phrase is defined in Section 2(a)(42) of the 1940
Act) of such Fund and the approval by the vote of a majority of the Trustees of
IDEX who are not parties hereto or interested persons (as that term is defined
in Section 2(a)(19) of the 1940 Act) of any such party, cast in person at a
meeting called for the purpose of voting on the approval of such amendment,
unless otherwise permitted by the 1940 Act.

      11. PRIOR AGREEMENTS. This agreement supersedes all prior agreements
between the parties relating to the subject matter hereof, and all such prior
agreements are deemed terminated upon the effectiveness of this agreement.

WHEREAS, Idex Management has entered into a Management and Investment Advisory

with IDEX Series Fund, a Massachusetts business trust (referred to herein as the
"Trust"), under which Idex Management has agreed among other things, to provide
management and administrative services to certain series of beneficial interest
in the Trust. (See Schedule A)

WHEREAS, the Advisory Agreement provides that Idex Management may engage the
Distributor to furnish it with management and administrative services to assist
Idex Management in carrying out certain of its functions under the Advisory
Agreement.

WHEREAS, it is the purpose of this Agreement to express the mutual agreement of
the parties hereto with respect to the services to be provided by the
Distributor to Idex Management and the terms and conditions under which such
services will be rendered.

NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth herein, the parties hereto agree as follows:

1.    SERVICES OF THE DISTRIBUTOR. The Distributor shall provide executive and
      management services to Idex Management and the Funds. Subject to the
      overall supervision of Idex Management and the Trustees, the Distributor
      shall furnish to the Funds the services of executive and administrative

      necessary office space, telephones and other communications facilities.

2.    OBLIGATIONS OF IDEX MANAGEMENT. Idex Management shall have the following
      obligations under this Agreement:

      (a)  to provide the Distributor with access to all information, documents
           and records of and about the Funds that are necessary to permit the
           Distributor to carry out its functions and responsibilities under
           this Agreement;

      (b)  to furnish the Distributor with a certified copy of any financial

      (c)  to compensate the Distributor for its services under this Agreement

           days during the period which this Agreement was in effect. The fees

Idex Management in carrying out certain of its functions under the Advisory
Agreement.

WHEREAS, it is the purpose of this Agreement to express the mutual agreement of
the parties hereto with respect to the services to be provided by the
Distributor to Idex Management and the terms and conditions under which such

      Agreement;

      (b) to furnish the Distributor with a certified copy of any financial
      statement or report prepared for the Funds by certified or independent

                  (FORM OF) PLAN OF DISTRIBUTION PURSUANT TO
             RULE 12B-1 UNDER THE INVESTMENT COMPANY ACT OF 1940

WHEREAS, IDEX Series Fund (the "Trust") is registered under the Investment
Company Act of 1940, as amended ("1940 Act"), as an open-end management
investment company, and offers for public sale shares of beneficial interest;

WHEREAS, the Trust desires to adopt a Plan of Distribution ("Plan") pursuant to
Rule 12b-1 under the 1940 Act applicable to the Class A shares of IDEX Blue Chip
Fund (the "Fund"), a series of shares of the Trust; and

WHEREAS, the Trust has entered into an Underwriting Agreement ("Underwriting
Agreement") with InterSecurities, Inc. ("ISI"), pursuant to which ISI serves as

continuous offering of its shares.

NOW THEREFORE, the Trust hereby adopts this Plan with respect to the Class A
shares of the Fund in accordance with Rule 12b-1 under the 1940 Act.

1.    (A). The Fund is authorized to pay to ISI, as compensation for ISI's
      services as Distributor of the Fund's Class A shares, a distribution fee
      at the rate of up to 0.35% on an annualized basis of the average daily net
      assets of the Fund's Class A shares. Such fee shall be calculated and
      accrued daily and paid monthly or at such other intervals as the Trust and
      ISI shall agree.

      (B). The Fund is authorized to pay to ISI, as compensation for ISI's
      services as Distributor of the Fund's Class A shares, a service fee at the
      rate of up to 0.25% on an annualized basis of the average daily net assets
      of the Fund's Class A shares. Such fee shall be calculated and accrued
      daily and paid monthly or at such other intervals as the Trust and ISI
      shall agree.

      (C). To the extent that the Fund pays a service fee pursuant to paragraph
      1(B) of this Plan, the amount available to be paid pursuant to paragraph
      1(A) of this Plan shall be reduced pro tanto, so that the total fees
      payable under this Plan by the Fund with respect to its Class A shares
      shall not exceed the rate of 0.35% on an annual basis of the average daily
      net assets of the Fund's Class A shares.

      (D). The Fund may pay a distribution or service fee to ISI at a lesser
      rate than the fees specified in paragraphs 1(A) and 1(B), respectively, of
      this Plan, in either case as agreed upon by the Trust and ISI and as
      approved in the manner specified in paragraph 4 of this Plan.

2. As Distributor of the Class A shares of the Fund, ISI may spend such amounts
as it deems appropriate on any activities or expenses primarily intended to
result in the sale of the Class A shares of the Fund or the servicing and/or
maintenance of Class A shareholder accounts, including, but not limited to:
compensation to employees of ISI; compensation to and expenses, including
overhead and telephone expenses, of ISI and other selected dealers who engage in
or support the distribution of shares or who service shareholder accounts; the

<PAGE>

3. This Plan shall not take effect with respect to the Class A shares of the
Fund unless it first has been approved, together with any related agreements, by
votes of a majority of both (a) the Board and (b) those Trustees of the Trust
who are not "interested persons" of the Trust and have no direct or indirect
financial interest in the operation of this Plan or any agreements related
thereto ("Independent Trustees"), cast in person at a meeting or (meetings)
called for the purpose of voting on such approval; and until the Trustees who
approve the Plan's taking effect have reached the conclusion required by Rule
12b-1(e) under the 1940 Act.

4. If approved as set forth in paragraph 3, this Plan shall continue thereafter
in full force and effect with respect to the Class A shares of the Fund for so
long as such continuance is specifically approved at least annually in the
manner provided for approval of this Plan in paragraph 3.

5. ISI shall provide to the Board and the Board shall review, at least
quarterly, a written report of the amounts expended by ISI under this Plan and
the Underwriting Agreement and the purposes for which such expenditures were
made. ISI shall submit only information regarding amounts expended for
"distribution activities," as defined in this paragraph 5, to the Board in
support of the distribution fee payable hereunder and shall submit only
information regarding amounts expended for "service activities," as defined in
this paragraph 5, to the Board in support of the service fee payable hereunder.

For purposes of this Plan, "distribution activities" shall mean any activities
in connection with ISI's performance of its obligations under this Plan or the
Underwriting Agreement that are not deemed "service activities." "Service
activities" shall mean activities in connection with the provision by ISI or
other entity of personal service and/or the maintenance of shareholder accounts
with respect to the Class A shares of the Fund, within the meaning of the
definition of "service fee" for purposes of Section 2830(b) (formerly Section
26(d)) of the Rules of Fair Practice of the National Association of Securities
Dealers, Inc. Overhead and other expenses of ISI related to its "distribution
activities" or "service activities," including telephone and other
communications expenses, may be included in the information regarding amounts
expended for such activities.

6. This Plan may be terminated at any time by vote of the Board, by vote of a
majority of the Independent Trustees, or by vote of a majority of the
outstanding voting securities of the Class A shares of the Fund.

7. This Plan may not be amended to increase materially the amount of fees
provided for in paragraph 1 hereof unless such amendment is approved by a vote
of a majority of the outstanding voting securities of the Class A shares of the
Fund, and no material amendment to the Plan shall be made unless approved in the
manner provided for approval and annual renewal in paragraph 4 hereof.

8. The amount of the fees payable by the Fund to ISI under paragraph 1 hereof
and the Underwriting Agreement is not related directly to expenses incurred by
ISI on behalf of the Fund in serving as Distributor of the Class A shares, and
paragraph 2 hereof and the Underwriting Agreement do not obligate the Trust to
reimburse ISI for such expenses. The fees set forth in paragraph 1 hereof will
be paid by the Fund to ISI unless and until either the Plan or the Underwriting
Agreement is terminated or not renewed with respect to the Class A shares. If
either the Plan or the Underwriting Agreement is terminated or not renewed with
respect to the Class A shares, any distribution expenses incurred by ISI on
behalf of the Class A shares of the Fund in excess of the payments of the fees
specified in paragraph 1 hereof and the Underwriting Agreement which ISI has
received or accrued through the termination date are the sole responsibility and
liability of ISI, and are not obligations of the Trust.

9. While this Plan is in effect, the selection and nomination of Trustees who
are not interested persons of the Trust shall be committed to the discretion of
the Trustees who are not interested persons of the Trust.

10. As used in this Plan, the terms "majority of the outstanding voting
securities" and "interested person" shall

<PAGE>

have the same meaning as those terms have in the 1940 Act.

11. The Trust shall preserve copies of this Plan (including any amendments
thereto) and any related agreements and all reports made pursuant to paragraph 5
hereof for a period of not less than six years from the date of this Plan, the
first two years in an easily accessible place.

IN WITNESS WHEREOF, the Trust has executed this Plan of Distribution on the day
and year set forth below in St. Petersburg, Florida.

Fund unless it first has been approved, together with any related agreements, by
votes of a majority of both (a) the Board and (b) those Trustees of the Trust
who are not "interested persons" of the Trust and have no direct or indirect
financial interest in the operation of this Plan or any agreements related
thereto ("Independent Trustees"), cast in person at a meeting or (meetings)

12b-1(e) under the 1940 Act.

4. If approved as set forth in paragraph 3, this Plan shall continue thereafter
in full force and effect with respect to the Class A shares of the Fund for so
long as such continuance is specifically approved at least annually in the
manner provided for approval of this Plan in paragraph 3.

support of the distribution fee payable hereunder and shall submit only
information regarding amounts expended for "service activities," as defined in
this paragraph 5, to the Board in support of the service fee payable hereunder.

For purposes of this Plan, "distribution activities" shall mean any activities
in connection with ISI's performance of its obligations under this Plan or the
Underwriting Agreement that are not deemed "service activities." "Service

other entity of personal service and/or the maintenance of shareholder accounts
with respect to the Class A shares of the Fund, within the meaning of the
definition of "service fee" for purposes of Section 2830(b) (formerly Section

majority of the Independent Trustees, or by vote of a majority of the
outstanding voting securities of the Class A shares of the Fund.

provided for in paragraph 1 hereof unless such amendment is approved by a vote
of a majority of the outstanding voting securities of the Class A shares of the
Fund, and no material amendment to the Plan shall be made unless approved in the

and the Underwriting Agreement is not related directly to expenses incurred by
ISI on behalf of the Fund in serving as Distributor of the Class A shares, and

reimburse ISI for such expenses. The fees set forth in paragraph 1 hereof will
be paid by the Fund to ISI unless and until either the Plan or the Underwriting
Agreement is terminated or not renewed with respect to the Class A shares. If

respect to the Class A shares, any distribution expenses incurred by ISI on
behalf of the Class A shares of the Fund in excess of the payments of the fees
specified in paragraph 1 hereof and the Underwriting Agreement which ISI has
received or accrued through the termination date are the sole responsibility and
liability of ISI, and are not obligations of the Trust.

9. While this Plan is in effect, the selection and nomination of Trustees who
are not interested persons of the Trust shall be committed to the discretion of
the Trustees who are not interested persons of the Trust.

<PAGE>

10. As used in this Plan, the terms "majority of the outstanding voting
securities" and "interested person" shall have the same meaning as those terms
have in the 1940 Act.

      For purposes of this Plan, "distribution activities" shall mean any

Plan or the Underwriting Agreement that are not deemed "service activities."
"Service activities" shall mean activities in connection with the provision by

respect to the Class B shares, any distribution expenses incurred by ISI on
behalf of the Class B shares of the Fund in excess of the payments of the fees
specified in paragraph 1 hereof and the Underwriting Agreement which ISI has
received or accrued through the termination date are the sole responsibility and
liability of ISI, and are not obligations of the Trust.

10. While this Plan is in effect, the selection and nomination of Trustees who
are not interested persons of the Trust shall be committed to the discretion of
the Trustees who are not interested persons of the Trust.

11. As used in this Plan, the terms "majority of the outstanding voting

WHEREAS, the Trust desires to adopt a Plan of Distribution ("Plan") pursuant to
Rule 12b-1 under the 1940 Act applicable to the Class B shares of IDEX Small-Cap

NOW THEREFORE, the Trust hereby adopts this Plan with respect to the Class B
shares of the Fund in accordance with Rule 12b-1 under the 1940 Act.

1.    (A). The Fund is authorized to pay to ISI, as compensation for ISI's
      services as Distributor of the Fund's Class B shares, a distribution fee
      at the rate of up to 0.75% on an annualized basis of the average daily net
      assets of the Fund's Class B shares. Such fee shall be calculated and
      accrued daily and paid monthly or at such other intervals as the Trust and
      ISI shall agree.

      (B). The Fund is authorized to pay to ISI, as compensation for ISI's
      services as Distributor of the Fund's Class B shares, a service fee at the
      rate of up to 0.25% on an annualized basis of the average daily net assets
      of the Fund's Class B shares. Such fee shall be calculated and accrued
      daily and paid monthly or at such other intervals as the Trust and ISI
      shall agree.

      (C). The total fees payable under this Plan by the Fund with respect to
      its Class B shares shall not exceed the maximum rate of 1.00% on an annual
      basis of the average daily net assets of the Fund's Class B shares.

      (D). The Fund may pay a distribution or service fee to ISI at a lesser

      this Plan, in either case as agreed upon by the Trust and ISI and as
      approved in the manner specified in paragraph 4 of this Plan.

2. As Distributor of the Class B shares of the Fund, ISI may spend such amounts
as it deems appropriate on any activities or expenses primarily intended to
result in the sale of the Class B shares of the Fund or the servicing and/or
maintenance of Class B shareholder accounts, including, but not limited to:
compensation to employees of ISI; compensation to and expenses, including
overhead and telephone expenses, of ISI and other selected dealers who engage in

<PAGE>

3. This Plan shall not take effect unless it first has been approved by a vote
of a majority of the outstanding voting securities of the Class B shares of the
Fund.

4. This Plan shall not take effect with respect to the Class B shares of the
Fund unless it first has been approved, together with any related agreements, by
votes of a majority of both (a) the Board and (b) those Trustees of the Trust
who are not "interested persons" of the Trust and have no direct or indirect
financial interest in the operation of this Plan or any agreements related
thereto ("Independent Trustees"), cast in person at a meeting or (meetings)
called for the purpose of voting on such approval; and until the Trustees who
approve the Plan's taking effect have reached the conclusion required by Rule
12b-1(e) under the 1940 Act.

5. If approved as set forth in paragraphs 3 and 4, this Plan shall continue
thereafter in full force and effect with respect to the Class B shares of the
Fund for so long as such continuance is specifically approved at least annually
in the manner provided for approval of this Plan in paragraph 4.

6. ISI shall provide to the Board and the Board shall review, at least
quarterly, a written report of the amounts expended by ISI under this Plan and
the Underwriting Agreement and the purposes for which such expenditures were
made. ISI shall submit only information regarding amounts expended for
"distribution activities," as defined in this paragraph 6, to the Board in
support of the distribution fee payable hereunder and shall submit only
information regarding amounts expended for "service activities," as defined in
this paragraph 6, to the Board in support of the service fee payable hereunder.

      For purposes of this Plan, "distribution activities" shall mean any
activities in connection with ISI's performance of its obligations under this
Plan or the Underwriting Agreement that are not deemed "service activities."
"Service activities" shall mean activities in connection with the provision by
ISI or other entity of personal service and/or the maintenance of shareholder
accounts with respect to the Class B shares of the Fund, within the meaning of
the definition of "service fee" for purposes of Section 2830(b) (formerly
Section 26(d)) of the Rules of Fair Practice of the National Association of
Securities Dealers, Inc. Overhead and other expenses of ISI related to its
"distribution activities" or "service activities," including telephone and other
communications expenses, may be included in the information regarding amounts
expended for such activities.

7. This Plan may be terminated at any time by vote of the Board, by vote of a
majority of the Independent Trustees, or by vote of a majority of the
outstanding voting securities of the Class B shares of the Fund.

8. This Plan may not be amended to increase materially the amount of fees
provided for in paragraph 1 hereof unless such amendment is approved by a vote
of a majority of the outstanding voting securities of the Class B shares of the
Fund, and no material amendment to the Plan shall be made unless approved in the
manner provided for approval and annual renewal in paragraph 5 hereof.

9. The amount of the fees payable by the Fund to ISI under paragraph 1 hereof
and the Underwriting Agreement is not related directly to expenses incurred by
ISI on behalf of the Fund in serving as Distributor of the Class B shares, and
paragraph 2 hereof and the Underwriting Agreement do not obligate the Trust to
reimburse ISI for such expenses. The fees set forth in paragraph 1 hereof will
be paid by the Fund to ISI unless and until either the Plan or the Underwriting
Agreement is terminated or not renewed with respect to the Class B shares. If
either the Plan or the Underwriting Agreement is terminated or not renewed with
respect to the Class B shares, any distribution expenses incurred by ISI on
behalf of the Class B shares of the Fund in excess of the payments of the fees
specified in paragraph 1 hereof and the Underwriting Agreement which ISI has
received or accrued through the termination date are the sole responsibility and
liability of ISI, and are not obligations of the Trust.

10. While this Plan is in effect, the selection and nomination of Trustees who
are not interested persons of

<PAGE>

the Trust shall be committed to the discretion of the Trustees who are not
interested persons of the Trust.

11. As used in this Plan, the terms "majority of the outstanding voting
securities" and "interested person" shall have the same meaning as those terms
have in the 1940 Act.

12. The Trust shall preserve copies of this Plan (including any amendments
thereto) and any related agreements and all reports made pursuant to paragraph 6
hereof for a period of not less than six years from the date of this Plan, the

WHEREAS, the Trust desires to adopt a Plan of Distribution ("Plan") pursuant to

WHEREAS, the Trust has entered into an Underwriting Agreement ("Underwriting

continuous offering of its shares.

NOW THEREFORE, the Trust hereby adopts this Plan with respect to the Class C

      its Class C shares shall not exceed the maximum rate of 0.90% on an annual

      extent the sum of any service fee paid under Paragraph 1(B) plus the

      maximum rate of 0.90%, the distribution fee paid under paragraph 1(A)
      shall be reduced pro tanto so that such maximum rate is not exceeded.

      (D). The Fund may pay a distribution or service fee to ISI at a lesser

             RULE 12B-1 UNDER THE INVESTMENT COMPANY ACT OF 1940

WHEREAS, IDEX Series Fund (the "Trust") is registered under the Investment
Company Act of 1940, as amended ("1940 Act"), as an open-end management
investment company, and offers for public sale shares of beneficial interest;

WHEREAS, the Trust desires to adopt a Plan of Distribution ("Plan") pursuant to
Rule 12b-1 under the 1940 Act applicable to the Class C shares of IDEX Mid-Cap
Opportunities Fund (the "Fund"), a series of shares of the Trust; and

WHEREAS, the Trust has entered into an Underwriting Agreement ("Underwriting
Agreement") with InterSecurities, Inc. ("ISI"), pursuant to which ISI serves as
Distributor of the various series and classes of shares of the Trust during the
continuous offering of its shares.

NOW THEREFORE, the Trust hereby adopts this Plan with respect to the Class C
shares of the Fund in accordance with Rule 12b-1 under the 1940 Act.

1.    (A). The Fund is authorized to pay to ISI, as compensation for ISI's
      services as Distributor of the Fund's Class C shares, a distribution fee
      at the rate of up to 0.75% on an annualized basis of the average daily net
      assets of the Fund's Class C shares. Such fee shall be calculated and
      accrued daily and paid monthly or at such other intervals as the Trust and
      ISI shall agree.

      (B). The Fund is authorized to pay ISI, as compensation for ISI's services
      as Distributor of the Fund's Class C shares, a service fee at the rate of

      extent the sum of any service fee paid under Paragraph 1(B) plus the

      maximum rate of 0.90%, the distribution fee paid under paragraph 1(A)
      shall be reduced pro tanto so that such maximum rate is not exceeded.

      (D). The Fund may pay a distribution or service fee to ISI at a lesser
      rate than the fees specified in paragraphs 1(A) and 1(B), respectively, of
      this Plan, in either case as agreed upon by the Trust and ISI and as

who are not "interested persons" of the Trust and have no direct or indirect
financial interest in the operation of this Plan or any agreements related
thereto ("Independent Trustees"), cast in person at a meeting or (meetings)

For purposes of this Plan, "distribution activities" shall mean any activities

other entity of personal service and/or the maintenance of shareholder accounts

behalf of the Class C shares of the Fund in excess of the payments of the fees
specified in paragraph 1 hereof and the Underwriting Agreement which ISI has
received or accrued through the termination date are the sole responsibility and
liability of ISI, and are not obligations of the Trust.

the Trustees who are not interested persons of the Trust.

                  (FORM OF) PLAN OF DISTRIBUTION PURSUANT TO
             RULE 12B-1 UNDER THE INVESTMENT COMPANY ACT OF 1940

WHEREAS, IDEX Series Fund (the "Trust") is registered under the Investment
Company Act of 1940, as amended ("1940 Act"), as an open-end management
investment company, and offers for public sale shares of beneficial interest;

WHEREAS, the Trust desires to adopt a Plan of Distribution ("Plan") pursuant to
Rule 12b-1 under the 1940 Act applicable to the Class C shares of IDEX Mid-Cap
Opportunities Fund (the "Fund"), a series of shares of the Trust; and

WHEREAS, the Trust has entered into an Underwriting Agreement ("Underwriting
Agreement") with InterSecurities, Inc. ("ISI"), pursuant to which ISI serves as
Distributor of the various series and classes of shares of the Trust during the
continuous offering of its shares.

NOW THEREFORE, the Trust hereby adopts this Plan with respect to the Class C
shares of the Fund in accordance with Rule 12b-1 under the 1940 Act.

1.    (A). The Fund is authorized to pay to ISI, as compensation for ISI's
      services as Distributor of the Fund's Class C shares, a distribution fee
      at the rate of up to 0.75% on an annualized basis of the average daily net
      assets of the Fund's Class C shares. Such fee shall be calculated and
      accrued daily and paid monthly or at such other intervals as the Trust and
      ISI shall agree.

      (B). The Fund is authorized to pay ISI, as compensation for ISI's services
      as Distributor of the Fund's Class C shares, a service fee at the rate of
      up to 0.25% on an annualized basis of the average daily net assets of the
      Fund's Class C shares. Such fee shall be calculated and accrued daily and
      paid monthly or at such other intervals as the Trust and ISI shall agree.

      (C). The total fees payable under this Plan by the Fund with respect to
      its Class C shares shall not exceed the maximum rate of 0.90% on an annual
      basis of the average daily net assets of the Fund's Class C shares. To the
      extent the sum of any service fee paid under Paragraph 1(B) plus the
      distribution fee paid under paragraph 1(A) would otherwise exceed such
      maximum rate of 0.90%, the distribution fee paid under paragraph 1(A)
      shall be reduced pro tanto so that such maximum rate is not exceeded.

      (D). The Fund may pay a distribution or service fee to ISI at a lesser
      rate than the fees specified in paragraphs 1(A) and 1(B), respectively, of
      this Plan, in either case as agreed upon by the Trust and ISI and as
      approved in the manner specified in paragraph 4 of this Plan.

2. As Distributor of the Class C shares of the Fund, ISI may spend such amounts
as it deems appropriate on any activities or expenses primarily intended to

information and reports for other than existing shareholders; and the costs of
preparing, printing and distributing sales literature and advertising materials.

3. This Plan shall not take effect unless it first has been approved by a vote
of a majority of the outstanding voting securities of the Class C shares of the
Fund.

4. This Plan shall not take effect with respect to the Class C shares of the
Fund unless it first has been approved, together with any related agreements, by
votes of a majority of both (a) the Board and (b) those Trustees of the Trust
who are not "interested persons" of the Trust and have no direct or indirect
financial interest in the operation of this Plan or any agreements related
thereto ("Independent Trustees"), cast in person at a meeting or (meetings)
called for the purpose of voting on such approval; and until the Trustees who
approve the Plan's taking effect have reached the conclusion required by Rule
12b-1(e) under the 1940 Act.

5. If approved as set forth in paragraphs 3 and 4, this Plan shall continue
thereafter in full force and effect with respect to the Class C shares of the
Fund for so long as such continuance is specifically approved at least annually
in the manner provided for approval of this Plan in paragraph 4.

support of the distribution fee payable hereunder and shall submit only
information regarding amounts expended for "service activities," as defined in
this paragraph 6, to the Board in support of the service fee payable hereunder.

For purposes of this Plan, "distribution activities" shall mean any activities
in connection with ISI's performance of its obligations under this Plan or the
Underwriting Agreement that are not deemed "service activities." "Service
activities" shall mean activities in connection with the provision by ISI or
other entity of personal service and/or the maintenance of shareholder accounts
with respect to the Class C shares of the Fund, within the meaning of the
definition of "service fee" for purposes of Section 2830(b) (formerly Section
26(d)) of the Rules of Fair Practice of the National Association of Securities
Dealers, Inc. Overhead and other expenses of ISI related to its "distribution
activities" or "service activities," including telephone and other
communications expenses, may be included in the information regarding amounts
expended for such activities.

7. This Plan may be terminated at any time by vote of the Board, by vote of a
majority of the Independent Trustees, or by vote of a majority of the
outstanding voting securities of the Class C shares of the Fund.

8. This Plan may not be amended to increase materially the amount of fees
provided for in paragraph 1 hereof unless such amendment is approved by a vote
of a majority of the outstanding voting securities of the Class C shares of the
Fund, and no material amendment to the Plan shall be made unless approved in the

respect to the Class C shares, any distribution expenses incurred by ISI on
behalf of the Class C shares of the Fund in excess of the payments of the fees
specified in paragraph 1 hereof and the Underwriting Agreement which ISI has
received

<PAGE>

or accrued through the termination date are the sole responsibility and
liability of ISI, and are not obligations of the Trust.

10. While this Plan is in effect, the selection and nomination of Trustees who
are not interested persons of the Trust shall be committed to the discretion of
the Trustees who are not interested persons of the Trust.

11. As used in this Plan, the terms "majority of the outstanding voting
securities" and "interested person" shall have the same meaning as those terms
have in the 1940 Act.

12. The Trust shall preserve copies of this Plan (including any amendments
thereto) and any related agreements and all reports made pursuant to paragraph 6
hereof for a period of not less than six years from the date of this Plan, the
first two years in an easily accessible place.

IN WITNESS WHEREOF, the Trust has executed this Plan of Distribution on the day

and the Underwriting Agreement is not related directly to expenses incurred by
ISI on behalf of the Fund in serving as Distributor of the Class C shares, and
paragraph 2 hereof and the Underwriting Agreement do not obligate the Trust to
reimburse ISI for such expenses. The fees set forth in paragraph 1 hereof will
be paid by the Fund to ISI unless and until either the Plan or the Underwriting
Agreement is terminated or not renewed with respect to the Class C shares. If
either the Plan or the Underwriting Agreement is terminated or not renewed with
respect to the Class C shares, any distribution expenses incurred by ISI on
behalf of the Class C shares of the Fund in excess of the payments of the fees
specified in paragraph 1 hereof and the Underwriting Agreement which ISI has
received or accrued through the termination date are the sole responsibility and
liability of ISI, and are not obligations of the Trust.
