 IMPORTANT INFORMATION FOR SHAREHOLDERS OF IDEX MUNDER NET50, IDEX TRANSAMERICA
  SMALL COMPANY, AND IDEX PILGRIM BAXTER TECHNOLOGY TO HELP YOU UNDERSTAND AND
                             VOTE ON THE PROPOSALS

     Please read the enclosed prospectus/proxy statement for a complete
description of the proposals.  However, as a quick reference, the following
questions and answers provide a brief overview of the proposals:

Q.  ON WHAT PROPOSALS AM I BEING ASKED TO VOTE?
A.  Shareholders are being asked to:

- -  Consider, on behalf of the funds in which they own shares) an Agreement and
Plan of Reorganization for the transfer of all of the assets, less liabilities,
of IDEX Munder Net50, IDEX Transamerica Small Company and IDEX Pilgrim Baxter
Technology in exchange for shares of Pilgrim Baxter Mid Cap Growth.

- -  Re-elect the current Trustees of IDEX and elect two new Trustees to the Board
of Trustees.

- -  To permit IDEX Management, Inc. ("IMI"), after obtaining the approval of the
Board of Trustees of the Fund (the "Board"), to enter into and materially amend
Sub-Advisory Agreements with non-affiliated sub-advisers for the Fund, without
obtaining shareholder approval.

Q.  WHAT HAPPENS IF SHAREHOLDERS DECIDE IN FAVOR OF THE EXCHANGE?

A.  A closing date will be set for the reorganization.  Shareholders will
receive full and fractional shares of IDEX Pilgrim Baxter Mid Cap Growth (the
"Acquiring Fund") equal in value to the shares of IDEX Munder Net50, IDEX
Transamerica Small Company and/or IDEX Pilgrim Baxter Technology (each a "Fund,"
collectively, the "Funds") that they owned on the Closing Date.  The net asset
value per share of the Acquiring Fund will not be affected by the transaction.
So the reorganization will not result in a dilution of any shareholder's
interest.

Q.  WHAT ARE THE ADVANTAGES OF MERGING THE FUNDS?

A.  There are three key potential advantages:
    Pilgrim Baxter & Associates, Ltd. Is recognized as a stellar money manager
    in the mutual fund industry.

    By combining the funds, shareholders may enjoy lower expense ratios over
    time. Larger funds tend to enjoy economies of scale not available to funds
    with smaller assets under management.

    These lower costs may lead to stronger performance, since total return to a
    fund's shareholders is net of fund expenses.

    The potential benefits are explained in more detail in the enclosed
    prospectus/proxy statement.

Q.  HOW ARE THESE FUNDS ALIKE?
A.  All funds growth of capital and are categorized as Aggressive Growth Funds.

Q.  IF THE FUNDS MERGE, WILL THERE BE TAX CONSEQUENCES FOR ME?

A.  Unlike a transaction where you direct IDEX to sell shares of one fund in
    order to buy shares of another, the reorganization will not be considered a
    taxable event. The funds themselves will recognize no gains or losses on
    assets as a result of a reorganization. So you will not have reportable
    capital gains or losses due to the reorganization.


R.  WHY ARE INDIVIDUALS RECOMMENDED FOR ELECTION TO THE BOARD OF TRUSTEES?

A.  IDEX is devoted to serving the needs of its shareholders, and the Board is
    responsible for managing the Fund's business affairs to meet those needs.
    The Board represents the shareholders and can exercise all of the Fund's
    powers, except those reserved for shareholders.

    Trustees are selected for election to the Board on the basis of their
education and professional experience. Candidates are chosen based on their
distinct interest in, and capacity for understanding the complexities of, the
operation of a mutual fund. These individuals bring considerable experience to
the impartial oversight of a Fund's operation.

  The Proxy Statement includes a brief description of each nominee's history and
current position with IDEX, if applicable.

Q.  WHY AM I BEING ASKED TO APPROVE A PROPOSAL TO PERMIT IMI TO ENTER INTO, OR
AMEND, A SUB-ADVISORY AGREEMENT WITHOUT SHAREHOLDER APPROVAL?

A.   The Board felt that it was in the best interest of IDEX and its
shareholders to permit IMI to have maximum flexibility to select, supervise and
evaluate sub-advisers, without incurring the unnecessary delay or expense of
obtaining shareholder approval because it will allow each fund to operate more
efficiently.  Currently, a shareholders' meeting must be held to appoint a sub-
adviser or materially amend a sub-advisory agreement.  This necessitates
creation and distribution of proxy materials, and solicitation of proxy votes
from shareholders.  This process is timely and costly.  The Board also feels
that IMI has significant experience and expertise in working with, and
selecting, sub-advisers.

Q.  HOW MANY VOTES DO YOU NEED TO APPROVE THESE PROPOSALS?

A.  We need a plurality, or a majority of the votes cast, to approve the
proposal to elect the Trustees, we need the affirmative vote of a majority of
each applicable fund's outstanding voting securities, as defined by the
Investment Company Act of 1940, for the fund specific proposals.

Q.  WHAT IF WE DO NOT HAVE ENOUGH VOTES TO MAKE THE DECISIONS BY THE SCHEDULED
SHAREHOLDER MEETING DATE?

A.  If we do not receive sufficient votes to hold the meeting, we or ALAMO
Direct, a proxy solicitation firm, may contact you by mail or telephone to
encourage you to vote.  Shareholders should review the proxy materials carefully
and cast their vote to avoid additional mailings or telephone calls.  If we do
not have enough votes to approve the proposals by the time of the shareholder
meeting at 11:00 a.m. on February 12, 2002, the meeting may be adjourned to
permit further solicitation of proxy votes.

Q.  HAS THE BOARD APPROVED THE PROPOSALS?
A.  Yes.  The IDEX Board has approved all of the proposals and recommends that
you vote "FOR" each applicable proposal.

Q.  HOW MANY VOTES AM I ENTITLED TO CAST?

A.  As a shareholder, you are entitled to one vote for each share of each fund
that you own, and fractional votes to reflect the fractional shares that you own
on the record date, November 26, 2001.

Q.  HOW DO I VOTE MY SHARES?

A.  You can vote your shares by mail, via the Internet, by telephone or by
facsimile.  To vote by mail, complete and sign the enclosed proxy card, and mail
it in the enclosed, postage paid-envelope.

Dear Shareholder:

        As a shareholder of IDEX Munder Net50, IDEX Transamerica Small Company
and/or IDEX Pilgrim Baxter Technology (each a "Fund," or collectively, the
"Funds"), you are entitled to vote on the following proposals that are described
below and in the enclosed materials:

1.  To consider an Agreement and Plan of Reorganization providing for the
    transfer of all of the assets, subject to liabilities, of the Funds to IDEX
    Pilgrim Baxter Mid Cap Growth (the "Acquiring Fund") in exchange for
    Acquiring Fund Shares and the assumption by the Acquiring Fund of the Funds'
    stated liabilities (the "Exchange" or the "Reorganization"). The shares of
    the Acquiring Fund received in the Exchange will be distributed by the Fund
    to its shareholders in liquidation of the Funds, after which each Fund will
    be dissolved;
2.  To re-elect the current Trustees of the Board and to elect two new Trustees
    to the Board;
3.  To consider approval of a proposal permitting IDEX Management, Inc. ("IMI"),
    after obtaining the approval of the Board of Trustees of IDEX (the "Board"),
    to enter into and materially amend sub-advisory agreements with
    non-affiliated sub-advisers on behalf of each Fund and future funds, without
    obtaining shareholder approval ("Sub-Adviser Approval Policy");
as set forth in the Prospectus/Proxy Statement accompanying this notice, and to
transact such other business as may properly come before the meeting and any
adjournments. The Board is not aware of any other business to come before the
meeting.

        The IDEX Board of Trustees (the "Board") has determined that it would be
in the best interest of each Fund and its shareholders if each Fund were to
exchange its assets (subject to liabilities) for shares of the Acquiring Fund
resulting in a larger asset base that may result in overall reductions of fees
for shareholders.

        The first proposal provides that each Fund exchange all of its assets,
subject to liabilities, for shares of the Acquiring Fund. Promptly thereafter,
each Fund will distribute pro rata the Acquiring Fund shares received in the
Exchange to its shareholders in complete liquidation of each Fund. Thus, each
Fund shareholder will receive for his or her Fund shares a number of Acquiring
Fund shares equal to the aggregate NET ASSET VALUE of the shareholder's Fund
shares as of the date of the Exchange.

        Here are some facts about the Exchange that will be useful to you as you
vote:

        o  There will be no cost to you to become a shareholder of the Acquiring
           Fund
        o  In the opinion of counsel, the Exchange will be free from Federal
           income taxes to you, each Fund and Acquiring Fund
        o  The holding period and aggregate tax basis of the Acquiring Fund
           shares you receive in the Exchange will be the same as the holding
           period and aggregate tax basis of your Fund shares
        o  You will be able to redeem your shares of the Acquiring Fund for cash
           at net asset value without any redemption fees or required holding
           period
        o  Shares of the Acquiring Fund are priced each day the New York Stock
           Exchange is open for business and you may redeem all or a part of
           your shares at the then-current net asset value per share


        o  As a shareholder of the Acquiring Fund, you will have the ability to
           exchange your shares of other open-end funds in the IDEX family of
           funds

        Further information about the transaction is contained in the enclosed
materials, which you should review carefully.

        You are also being asked to re-elect the current members of the IDEX
Board Trustees and to elect two new Trustees to the Board.

        Finally you are being asked to consider a proposal to permit IMI, after
obtaining Board approval, to enter into and materially amend Sub-Advisory
Agreements on behalf of each Fund with non-affiliated sub-advisers without
obtaining shareholder approval. This Sub-Adviser Approval Policy may result in
cost savings to IDEX and its shareholders.

        A Question and Answer section is included regarding this proxy and its
proposals.

        For your convenience, you may vote by mail, by telephone, via the
internet or by facsimile.

To the shareholders of IDEX Munder Net50, IDEX Transamerica Small Company and/or

for the following purposes:

1.  To consider an Agreement and Plan of Reorganization providing for the
    transfer of all of the assets, subject to liabilities, of each Fund to IDEX
    Pilgrim Baxter Mid Cap Growth (the "Acquiring Fund") in exchange for
    Acquiring Fund shares and the assumption by the Acquiring Fund of each
    Fund's stated liabilities (the "Exchange" or the "Reorganization"). The
    shares of the Acquiring Fund received in the Exchange will be distributed by
    each Fund to its shareholders in liquidation of each Fund, after which each
    Fund will be dissolved;
2.  To re-elect the current Trustees of the Board and to elect two new Trustees
    to the Board;
3.  To consider approval of a proposal permitting IDEX Management, Inc. ("IMI"),

    non-affiliated sub-advisers on behalf of each Fund and future funds, without
    obtaining shareholder approval ("Sub-Adviser Approval Policy");

as set forth in the Prospectus/Proxy Statement accompanying this notice, and to

                          SUMMARY - Re: REORGANIZATION
                                 PROPOSAL No. 1
- --------------------------------------------------------------------------------

This Summary is qualified by reference to the more complete information
contained elsewhere in this Prospectus/Proxy Statement, the IDEX Prospectus
(which contains information about each Fund and the Acquiring Fund, dated March
1, 2001) the Annual and Semi-Annual Reports, and the form of Agreement and Plan
of Reorganization attached to this Prospectus/Proxy Statement as Exhibit A.

PROPOSED TRANSACTION. The IDEX Board, including Board members who are not
"interested persons" (as defined in the Investment Company Act of 1940, as
amended ("1940 Act")), has approved an Agreement and Plan of Reorganization (the
"Plan"). The Plan provides that, subject to the requisite approval of each
Fund's shareholders, on the date of the Exchange each Fund will assign, transfer
and convey to the Acquiring Fund all of the assets (subject to liabilities) of
such Fund, including all securities and cash, in exchange for shares of the
acquiring Fund having an aggregate net asset value equal to the value of each
Fund's net assets. Each Fund will distribute all Acquiring Fund shares received
by it among its shareholders so that each shareholder will receive a pro rata
net asset value equal to the aggregate net asset value of the shareholder's Fund
shares as of the date of the Exchange. Thereafter, each Fund will be dissolved.

As a result of the Exchange, each Fund's shareholders will cease to be a
shareholder of the Fund and will become a shareholder of the Acquiring Fund as
of the close of business on the date of the Exchange.

Your Fund's investment manager, IMI, proposed to the Board a reorganization of
each Fund with and into the Acquiring Fund so that shareholders of each Fund may
become shareholders of a substantially larger fund advised by the same
investment adviser with generally historically better long-term performance, and
lower fund expenses. The Board also considered the fact that the surviving fund
has the potential for lower overall operating expenses. The Board also
considered that each Fund and the Acquiring Fund offer Class A, Class B, Class C
and Class M shares under identical sales charge arrangements. The Board also
considered that the Reorganization would be a tax-free reorganization, and there
would be no sales charge imposed in effecting the Reorganization.

The IDEX Board has concluded that the Exchange would be in the best interests of
each Fund and its shareholders, and the interests of existing shareholders of
each Fund would not be diluted as a result of the transactions contemplated by
the Exchange. See "Reasons for the Exchange."

TAX CONSEQUENCES. As a condition to the closing of the Exchange, each Fund and
the Acquiring Fund will receive an opinion of counsel to the effect that, for
Federal income tax purposes, (a) no gain or loss will be recognized by the
Fund's shareholders as a result of the Exchange, (b) the holding period and
aggregate tax basis of Acquiring Fund shares received by a Fund shareholder will
be the same as the holding period and aggregate tax basis of the shareholder's
Fund shares, and (c) the holding period and tax basis of each Fund's assets
transferred to the Acquiring Fund as a result of the Exchange will be the same
as the holding period and tax basis of such assets held by each Fund immediately
prior to the Exchange. See "Information about the Exchange - Federal Income Tax
Consequences."

COMPARISON OF EACH FUND AND THE ACQUIRING FUND. The following discussion is
primarily a summary of certain parts of each Fund's Prospectus, as amended, and
the Acquiring Fund's Prospectus. Information contained in this Prospectus/Proxy
Statement is qualified by the more complete information set forth in such IDEX
Prospectus, which are incorporated herein by reference.

Objectives.  Each Fund has the following investment objectives:

        IDEX Munder Net50:   Seeks to provide long-term capital appreciation.
        IDEX Transamerica Small Company:    Seeks to maximize long-term growth.
        IDEX Pilgrim Baxter Technology:     Seeks growth of capital.
        Acquiring Fund:             Seeks capital appreciation.

                                       4


Acquiring Fund and Funds. To pursue its goals, the Funds and the Acquiring Fund
invest principally in:

        IDEX Munder Net50: Stocks of domestic and foreign companies that are
        engaged in the Internet and Intranet related businesses.
        IDEX Transamerica Small Company: Equity securities such as common
        stocks, preferred stocks, rights, warrants and securities convertible
        into or exchangeable for common stocks of small companies.
        IDEX Pilgrim Baxter Technology: Common stocks of companies doing
        business in the technology and communications sectors of the market.
        Acquiring Fund: Common stocks of medium capitalization companies.

Strategies. IDEX Munder Net50: Under normal market conditions, the fund will
invest at least 65% of its total assets in equity securities and American
Depository Receipts ("ADRs") of both domestic and foreign companies that are
engaged in research, design, development manufacturing or engaged to a
significant extent in the business of distributing products, processes or
services for use with the Internet or Intranet related businesses. The fund
intends to hold approximately 50 different securities, but may hold between 40
and 60 securities at any time. Of the companies selected, 70-90% are expected to
be domestic, while 10-30% are expected to be foreign. There is no limit on the
market capitalization of the companies in which the fund may invest, or in the
length of operating history for the companies. The fund may invest without limit
in small companies and in initial public offerings. The principal risks for this
fund include stock risk, foreign stock risk, sector risk and small- and
medium-sized companies risk.

IDEX Transamerica Small Company: The fund uses a "bottom-up" approach to
investing and builds the fund's portfolio one company at a time by investing
fund assets principally in equity securities such as common stocks, preferred
stocks, rights, warrants and securities convertible into or exchangeable for
common stocks of small companies. The fund manager generally invests at least
65% of the fund's assets in equity securities of companies with a small market
capitalization (no more than $1 billion). The fund manager selects stocks for
small companies that show strong potential for steady growth and high barriers
to competition. The principal risks for this fund include stock risk,
convertible securities risk, small-cap companies risk and warrants and rights
risk.

IDEX Pilgrim Baxter Technology: The fund seeks its objective by investing
principally in common stocks of companies the technology and communications
sectors of the market. The fund manager generally invests at least 65% of the
fund's total assets in common stocks of small, medium or large capitalization
companies doing business in the technology and communications sectors of the
market. This fund is also concentrated which means Pilgrim Baxter invests 25% or
more of the fund's total assets in one or more industries within those sectors.
Pilgrim Baxter uses its own fundamental research and proprietary measures of
growth and business momentum in determining which stocks to buy and sell. The
principal risks for this fund include stock risk, technology stocks risk, and
small or medium sized companies risk.

IDEX Pilgrim Baxter Mid Cap Growth (Acquiring Fund): The fund seeks its
objective by investing principally in common stocks of medium capitalization
companies. In seeking capital appreciation, Pilgrim Baxter invests at least 65%
of the fund's total assets in common stocks, issued by companies with market
capitalizations or average revenues between $500 million and $10 billion. The
fund invests primarily in companies that Pilgrim Baxter believes have strong
business momentum, earnings growth and capital appreciation potential. Pilgrim
Baxter uses its own fundamental research and proprietary measures of growth and
business momentum in determining which stocks to buy and sell.

Description of Main Risks. The principal risks associates with an investment in
the Acquiring Fund are described below:

        Stock Risk - While stocks have historically outperformed other
investments 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 a fund holds fluctuate in price, the value of your investment in a
fund will go up and down.

                                       5


        Medium-Sized Companies Risk - 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.

See "Explanation of Strategies and Risks" in the IDEX Prospectus for a more
complete description of investment risks applicable to an investment in the
Acquiring Fund.

Fees and Expenses. The fees and expenses of each Fund set forth below are
estimated because each Fund has not been in existence for one full calendar
year. The fees and expenses for the Acquiring Fund are for the fiscal year ended
December 31, 2001. The "Pro Forma After Exchange" information is based on net
assets and fund accruals of each Fund and the Acquiring Fund as of ___________.
Annual fund operating expenses are paid out of fund assets, so their effect is
reflected in the fund's net asset value per share.

SHAREHOLDER FEES

The maximum sales charge (load) imposed on purchases (as a % of offering price)
for Class A shares is 5.50% and for Class M shares is 1.00%. The sales charge is

for Class B is 5.00% and 1.00% for Class M shares. The charge is not applicable

EXAMPLE:

        This example shows what you could pay in expenses over time. It will
help you compare the costs of investing in the Acquiring Fund with the costs of
investing in other mutual funds. It uses the same hypothetical conditions other
funds use in their prospectuses: $10,000 initial investment, 5% total return
each year and no changes in expenses. The return is for illustration purposes
only and is not guaranteed. Actual costs may be higher or lower.

PAST PERFORMANCE. The average total returns for the Acquiring Fund for Class A
shares were (21.84%) and 27.77% for one year and since inception respectively;
Class B shares (22.07%) and 29.74%; Class C Shares (17.97%) and 9.59%; and Class
M Shares (19.50%) and 30.39%. The total return for the year ended December 31,
2000 was (17.30%).

MANAGEMENT FEES: The investment advisory fee for IDEX Munder Net50 is an annual
rate of 1.00% of the first $1 billion of the fund's average daily net assets and
0.95% of average daily net assets over $1 billion. The investment advisory fee
for IDEX Transamerica Small Company is an annual rate of 0.80% of the first $500
million of the fund's average daily net assets and 0.70% of assets over $500
million. The investment advisory fee for IDEX Pilgrim Baxter Technology is an
annual rate of 1.00% of the first $500 million of the fund's average daily net
assets and 0.90% of assets over $500 million.

The current investment advisory fee for the Acquiring Fund is an annual rate of
0.80% of the first $500 million of the fund's average daily net assets and 0.70%
of the fund's average daily net assets over $500 million. For the fiscal year
ended October 31, 2000, IMI received $ 440,701, less reimbursements of $229,341,
for a net of $211,360 for investment advisory services on behalf of IDEX Pilgrim
Baxter Technology and did not receive any fees for IDEX Transamerica Small
Company as IMI paid $125,027 on behalf of the fund for reimbursements. IMI did
not receive any fees for services to IDEX Munder Net50 as it did not commence
operations until April 2001. The Acquiring Fund paid IMI $580,661, less
reimbursements of $ 373,224, for a net advisory fee of $207,437.

If the current advisory fee for the Acquiring Fund had been effect for the
fiscal year ended October 31, 2000, IDEX Munder Net50, IDEX Transamerica Small
Company and IDEX Pilgrim Baxter Technology would have paid IMI $________,
$______ and $_______, respectively, in investment advisory fees.

BOARD CONSIDERATION OF FEES. The Board reviewed the performance of each Fund,
the asset base of each Fund and the fees. It considered a variety of
alternatives potentially available to each Fund, including maintaining the
status quo or liquidating each Fund.

The Board then examined the nature, quality and scope of the services provided
to the Acquiring Fund by Pilgrim Baxter. They then reviewed the fee structure of
the Acquiring Fund, and analyzed the fee structure of each Fund. They reviewed
the fees of similar funds in the mutual fund industry. They also reviewed the
reputation and presence of Pilgrim Baxter in the mutual fund industry. They also
noted that both IDEX Pilgrim Baxter Technology and IDEX Munder Net 50
shareholders would realize a reduction in advisory fees under the Acquiring
Fund's fee structure.

The Board felt the combined higher net assets should enable the Acquiring Fund
to spread costs over accounting, legal and printing, and this larger asset base
may thereby potentially reduce the per share expense levels. The Board also
determined that higher net asset levels also may benefit portfolio management by
permitting larger individual portfolio investments that may result in reduced
transaction costs or more favorable pricing by providing the opportunity for
greater portfolio diversity.

The Board further determined that these benefits, in turn, should have a
favorable effect on the future economies of scale and eliminate certain costs
associated with operating separately. These factors, and the reputation of
American Century, resulted in the determination that reorganizing each Fund into
the Acquiring Fund, was in the best interest of each Fund and its shareholders.

to investors at a price equal to the net asset value of the shares at the time
of purchase. The Acquiring Fund's net asset value per share is determined as of
close of regular trading on the NYSE, on each day that the NYSE is open, by
dividing the value of the Acquiring Fund's net assets by the total number of
shares outstanding. The Acquiring Fund's investments generally are valued based

fair value as determined in good faith by the Acquiring Fund's Board. See
"Shareholder Information" in the IDEX Prospectus.

SHARE REDEMPTION PROCEDURES. A shareholder of the Acquiring Fund may redeem his
or her shares from the Acquiring Fund at any time during which IDEX is open for

after receipt of a proper request for redemption. See "Shareholder Information -
How to Sell Shares" in the IDEX Prospectus.

DIVIDENDS AND OTHER DISTRIBUTIONS. Both the Fund and the Acquiring Fund
distributes to its shareholders net investment income and any net realized
short-term capital gains _______, and net realized long-term capital gains, if
any, annually. Such dividends and distributions are automatically reinvested in
each Fund or Acquiring Fund shares at net asset value, unless the shareholder
requests cash. See "Shareholder Information - Distributions and Taxes" in the
IDEX SAI.

SHAREHOLDER RIGHTS. Both the Acquiring Fund and each Fund are part of a
Massachusetts Trust, and, thus, their shareholders have the same rights due them
under the state law. IDEX is not required to hold annual meetings of
shareholders and has no current intention to hold such meetings, except as
required by the 1940 Act. Under the 1940 Act, IDEX is required to hold a
shareholders' meeting if, among other reasons, the number of Trustees elected by
shareholders is less than a majority of the total number of Trustees, or if it
desires to change any fundamental investment policies. In addition, holders of
at least 10% of a fund's outstanding shares may require a fund to hold a
shareholder meeting for the purpose of voting on the removal of any Trustee.

                            REASONS FOR THE EXCHANGE

The Board, including a majority of its independent Trustees, has determined that
the exchange is in the best interests of each Fund. In approving the
Reorganization, the Board considered a number of factors, including:

        (1)     the compatibility of the Funds' investment objectives, policies
                and restrictions;
        (2)     the effect of Exchange on the expense ratio of the Acquiring
                Fund relative to each Fund's current expense ratio;
        (3)     the effect of the Exchange on the Funds' expected investment
                performance;
        (4)     the costs to be incurred by each Fund as a result of the
                Exchange;
        (5)     the tax consequences of the Exchange;
        (6)     possible alternatives to the Exchange, including whether each
                Fund should continue to operate on a stand-alone basis or should
                be liquidated;
        (7)     the potential benefits of the Exchange to IDEX and its
                respective shareholders.

The Exchange was recommended to the Board by IDEX at a meeting held on October
30, 2001. In recommending the Exchange, IDEX advised the Board that the
investment advisory fees for the Acquiring Fund would be equal to or less than
each Fund's fee. The Board considered the performance record of the Acquiring
Fund and of each Fund. The Board also considered that with greater net assets,
the Funds should reduce the expenses borne by shareholders as a percentage of
net assets. The Board was also advised that following the Exchange, the expense
ratio for the Acquiring Fund may decrease because the investment advisory fees
paid decrease as its size increases.

In determining whether to recommend approval of the Exchange, the Board
considered the following factors, among others: (1) the compatibility of the
Acquiring Fund and each Fund's investment objective and management policies, as
well as the services offered by IDEX to the Funds; (2) the terms and conditions
of the Exchange and whether the Exchange would result in dilution of shareholder
interests; (3) expense ratios and information regarding the fees and expenses of
the Acquiring Fund and each Fund, as well as the expense rations of similar
funds and the estimated expense ratio of the combined fund; (4) the tax
consequences of the Exchange; and (5) the estimated costs to be incurred by the
Acquiring Fund and each Fund as a result of the Exchange

                         INFORMATION ABOUT THE EXCHANGE

Plan Of Exchange. The following summary of the Plan is qualified in its entirety
by reference to the form of Plan attached to this Prospectus/Proxy Statement as
Exhibit A. The Plan provides that the Acquiring Fund will acquire

                                       11


all of the assets of each Fund at net asset value, in exchange for Acquiring
Fund shares and the assumption by the Acquiring Fund of each Fund's stated
liabilities on ____________, or such later date as may be agreed upon by the
parties (the "Closing Date"). The number of Acquiring Fund shares to be issued
to each Fund will be determined on the basis of the relative net asset values
per share and aggregate net assets of the shares of the Acquiring Fund and each
Fund, generally computed as of the close of trading on the floor of the NYSE
(currently at 4:00 p.m., New York time) on the Closing Date. Portfolio
securities of each Fund and the Acquiring Fund, which are described for the
Acquiring Fund under "Shareholder Information - Pricing of Shares" in the IDEX
Prospectus.

Prior to the Closing Date, each Fund will declare a dividend or dividends which,
together with all previous such dividends, will have the effect of distributing
to Fund shareholders all of each Fund's previously undistributed investment
company taxable income, if any, for the fiscal period ending on or prior to the
Closing Date (computed without regard to any deduction or dividends paid), its
net exempt interest income for the fiscal period ending on or prior to the
Closing Date, and all of its previously undistributed net capital gain realized
in the fiscal period ending on or prior to the Closing Date (after reduction for
any capital loss carried forward).

As conveniently as practicable after the Closing Date, each Fund will liquidate
and distribute pro rata to its shareholders of record as of the close of
business on the Closing Date, the shares received by it in the Exchange. Such
distribution and liquidation will be accomplished by establishing accounts on
the share records of the Acquiring Fund in the name of each Fund shareholder,
each account representing the respective pro rata number of Acquiring Fund
shares due to the shareholder. After such distribution and the winding up of its
affairs, each Fund will be dissolved. Some of the outstanding shares of each
Fund may be represented by physical certificates; however, in the interest of
economy and convenience, shares of the Acquiring Fund issued to Fund
shareholders pursuant to the Exchange, will be in uncertificated form. After the
Closing Date, any outstanding certificates representing Fund shares will be
void.

The Plan may be amended at any time prior to the Exchange. Each Fund will
provide its shareholders with information describing any material amendment to
the Plan prior to shareholder consideration. The obligations of each Fund and
the Acquiring Fund under the Plan are subject to various conditions, including
approval by Fund shareholders holding the requisite number of Fund shares and
the continuing accuracy of various representations and warranties of each Fund
and the Acquiring Fund being confirmed by the respective parties.

The Plan may be amended at any time prior to the Exchange. Each Fund will
provide its shareholders with information describing any material amendment to

the Acquiring Fund under the Plan are subject to various conditions, including
approval by Fund shareholders holding the requisite number of Fund shares and
the continuing accuracy of various representations and warranties of each Fund
and the Acquiring Fund being confirmed by the respective parties.

The total expenses of the Exchange are expected to be approximately $_____,
which will be borne pro rata according to the aggregate net assets of the
Acquiring Fund and each Fund on the date of the Exchange.

Federal Income Tax Consequences. The exchange of each Fund's assets for the
Acquiring Fund shares is intended to qualify for Federal income tax purposes as
a tax-free reorganization under Section 368(a) of the Code. As a condition to
the closing of the Exchange, each Fund and the Acquiring Fund will receive the
opinion of Sutherland Asbill & Brennan, LLP, counsel to each Fund and the
Acquiring Fund, to the effect that on the basis of the existing provisions of
the Code, Treasury regulations thereunder, current administrative regulations
and pronouncements and court decisions, and certain facts, assumptions and
representations, for Federal income tax purposes: (1) the transfer of all of
each Fund's assets in exchange for Acquiring Fund shares and the assumption by
the Acquiring Fund of each Fund's liabilities will constitute a "reorganization"
within the meaning of Section 368(a)(1)(C) of the Code with respect to each
Fund; (2) no gain or loss will be recognized by the Acquiring Fund upon receipt
of each Fund's assets solely in exchange for Acquiring Fund shares and the
assumption by the Acquiring Fund of liabilities of each Fund; (3) no gain or
loss will be recognized by each Fund upon transfer of its assets to the
Acquiring Fund in exchange for shares and the assumption by the Acquiring Fund
of each Fund's liabilities or upon the distribution (whether actual or
constructive) of Acquiring Fund shares to Fund shareholders in exchange for
their Fund shares; (4) no gain or loss will be recognized by Fund shareholders
upon the exchange of Fund shares for Acquiring Fund shares; (5) the aggregate
tax basis for Acquiring Fund shares received by each Fund shareholder pursuant
to the Exchange will be the same as the aggregate tax basis for Fund shares held
by such

                                       12


shareholder immediately prior to the Exchange, and the holding period of
Acquiring Fund shares to be received by a Fund shareholder will include the
period during which Fund shares surrendered in exchange therefor were held by
such shareholder (provided Fund shares were held as capital assets on the date
of the Exchange); and (6) the tax basis of Fund assets acquired by the Acquiring
Fund will be the same as the tax basis of such assets to each Fund immediately
prior to the Exchange, and the holding period of Fund assets in the hands of the
Acquiring Fund will include the period during which those assets were held by
each Fund.

NEITHER EACH FUND NOR THE ACQUIRING FUND HAS SOUGHT A TAX RULING FROM THE
INTERNAL REVENUE SERVICE ("IRS"). THE OPINION OF COUNSEL IS NOT BINDING ON THE
IRS NOR DOES IT PRECLUDE THE IRS FROM ADOPTING A CONTRARY POSITION. Fund
shareholders should consult their tax advisers regarding the effect, if any, of
the proposed Exchange in light of their individual circumstances. Since the
foregoing discussion relates only to the Federal income tax consequences of the
Exchange, Fund shareholders also should consult their tax advisors as to state
and local tax consequences, if any, of the Exchange.

                    REQUIRED VOTE AND BOARD'S RECOMMENDATION

The IDEX Board has approved the Plan and the Exchange on behalf of each Fund,
and has determined that (i) participation in the Exchange is in the best
interest of each Fund and its shareholders and (ii) the interests of
shareholders of each Fund will not be diluted as a result of the Exchange.
Pursuant to the IDEX charter documents, an affirmative vote of a majority of
each Fund's shares outstanding and entitled to vote is required to approve the
Plan and the Exchange.

           THE IDEX BOARD OF TRUSTEES, INCLUDING THE "NON-INTERESTED"
 TRUSTEES, RECOMMENDS THAT EACH FUND'S SHAREHOLDERS VOTE "FOR" PROPOSAL No. 1 -

Meeting pursuant to each Fund's Bylaws, which permit the election of Trustees at
any meeting required to be held. Election of the Trustees requires a vote of ALL
IDEX shareholders. Shareholders of other IDEX funds will be asked to vote for
the Trustees at a later date. The results of the Trustee election will be
effective March 1, 2002.

At a meeting held on June 14, 2001 (the "Board Meeting"), the Disinterested
Trustees unanimously nominated for re-election: Peter R. Brown, Charles C.
Harris, Jack E. Zimmerman, William W. Short, Jr., Daniel Calabria, John R.
Kenney, and Patrick S. Baird, the incumbent Trustees; and unanimously nominated
for election to the Board, Janice B. Case and Russell A. Kimball, Jr. The
Trustees are to be elected to serve until reaching their respective designated

                                       13


retirement ages or until their successors are duly elected and qualified.
Following the Special Meeting, IDEX does not contemplate holding regular
meetings of shareholders to elect Trustees or otherwise. Each of the nominees
named has agreed to serve as a Trustee if elected. However, should any nominee
become unable or unwilling to accept nomination or election, the proxies will be
voted for one or more substitute nominees designated by the Board.

The following sets forth the names, ages, principal occupations, and other
information respecting the nominees:

(1) Such Trustee is an "Interested Person" of the fund as defined in the 1940
    Act and an affiliated person of IDEX, and did not receive compensation
    directly from IDEX. Such Director is also an affiliated person of IMI.
(2) Mr. Zimmerman is the brother-in-law of John R. Kenney, Chairman of IDEX.

The Board met 4 times during the twelve months ended October 31, 2000 (the
"Period").

The Board's Audit Committee is composed of Messrs. Brown, Harris, and Short, and
met 2 times in the Period. All Audit Committee members are considered
"independent" under Rule 4200(a)(14) of the National Association of Securities
Dealers' listing standards. The functions performed by the Audit Committee
include the recommendation of the independent public accountants for IDEX to be
selected by the Board, the review of the scope and results of audit services,
the review of the adequacy of internal accounting and financial controls, the
review of material changes in accounting principals and practices and other
matters when requested from time to time by the Board. The Audit Committee has
adopted a charter to set forth its responsibilities (the "Charter"). A copy of
the Charter is attached to this Prospectus/Proxy Statement as Exhibit __

As required by the Charter, the Audit Committee received and reviewed the report
of PricewaterhouseCoopers (PWC), the independent public accountants for IDEX,
regarding the results of their audit, as well as the written disclosures and the
letter from PWC required by Independence Standards Board Standard No. 1. The
Audit Committee reviewed the audited financial statements with the management of
IDEX. A representative of PWC also discussed with the Audit Committee the
independence of PWC from IDEX, as well as the matters required to be

                                       15


discussed by Statement of Auditing Standards 61. Discussions between the Audit
Committee and the representative of PWC included the following:

o  PWC's responsibilities in accordance with generally accepted auditing
   standards
o  The initial selection of, and whether there were any changes in, significant
   accounting policies or their application
o  Management's judgments and accounting estimates
o  Whether there were any significant audit adjustments o Whether there were any
   disagreements with management
o  Whether there was any consultation with other accountants
o  Whether there were any major issues discussed with management prior to PWC's
   retention
o  Whether PWC encountered any difficulties in performing the audit
o  PWC's judgments about the quality of the IDEX accounting principles
o  PWC's responsibilities for information prepared by management that is
   included in documents containing audited financial statements

Based on its review of the financial statements and its discussions with
management and the representative of PWC, the Audit Committee did not become
aware of any material misstatements or omissions in the financial statements.
Accordingly, the Audit Committee recommended to the Board that the audited
financial statements be included in the Annual Report for the year ended October
31, 2000, and filed with the SEC.

During the year ended October 31, 2000, PWC billed IDEX $ 234,000 in fees for
professional services in connection with the audit of the annual financial
statements and review of SEC filings.

During the fiscal year ended October 31, 2000, no fees were incurred by IDEX
from PWC for professional accounting services to design, implement or manage,
hardware or software that collects or generates information significant to the
IDEX financial statements.

The Board's Nominating Committee is composed of Messrs. Brown, Harris, and
Short, and met 1 time during the Period. The functions performed by the
Nominating Committee includes making nominations for independent trustees, and
for membership on committees. The Nominating Committee will consider nominees
recommended by shareholders. Recommendations should be submitted in writing to
the Committee in care of the Secretary of IDEX at the address shown on page 1 of
this Proxy Statement.

Each Disinterested Trustee currently receives a total annual retainer fee of
$20,000, plus $4,000 and incidental expenses for each regular meeting attended

                  THE BOARD OF TRUSTEES OF THE FUND RECOMMENDS
                           A VOTE "FOR" PROPOSAL No. 2
- --------------------------------------------------------------------------------

Proposal No. 3: A Proposal To Permit IMI, After Obtaining Approval Of The Board,
To Enter Into And Materially Amend Sub-Advisory Agreements With Non-Affiliated
Investment Sub-Advisers On Behalf of each Fund Without Obtaining Shareholder
Approval.

At the Board Meeting held on September 11, 2000, the Trustees, including a
majority of the trustees 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 Trustees"), approved and recommended that
shareholders of each Fund approve a policy to permit the Investment Adviser, on
behalf of each Fund and subject to approval of the Board, to appoint
sub-advisers, to enter into sub-advisory agreements, and to materially amend
existing sub-advisory agreements (the "Sub-Adviser Approval Policy") without
further shareholder approval for the existing Funds of IDEX, and for future
Funds, subject to certain conditions. Special restrictions apply to the
Sub-Advisers that are affiliates of the Investment Adviser ("Affiliated
Sub-Adviser"). Implementation of the Sub-Adviser Approval Policy approved by the
Board is subject to the terms and conditions of an Exemptive Order from the SEC
as described below.

IDEX

IDEX Mutual Funds is a Massachusetts Trust organized as a diversified, open-end
management investment company under the 1940 Act. Shares of IDEX are registered
under the Securities Act of 1933 (the "1933 Act"), and IDEX itself is registered
under the 1940 Act on Form N-1A with the SEC. Idex Investor Services, Inc.
("IIS"), located at 570 Carillon Parkway, St. Petersburg, Florida 33716, an
affiliate of IDEX and IMI, serves as transfer agent and administrator for IDEX.
AFSG Securities Corporation, located at 4333 Edgewood Road, NE, Cedar Rapids,
Iowa 52499, serves as principal underwriter for IDEX. IDEX currently consists of
31 funds.

THE INVESTMENT ADVISER

IMI serves as investment adviser to IDEX. IMI does not currently act as an
investment adviser with respect to any registered investment company other than
IDEX. IMI has served as investment adviser of each Fund since each Fund's
inception.

IMI is registered as an investment adviser under the Investment Advisers Act of
1940, as amended (the "Advisers Act"). IMI has served as the investment adviser
to each Fund of IDEX since January 1, 1998. (Prior to that date,
InterSecurities, Inc. served as the investment adviser to various Funds in
existence prior to that date.) Pursuant to the Investment Advisory Agreement
between IDEX and IMI, dated ______, and subject to the supervision of the Board,
IMI is responsible for furnishing continuous advice and recommendations to IDEX
as to the acquisition, holding, or disposition of any or all the securities or
other assets that each Fund may own or contemplate acquiring from time to time.
The Investment Adviser's officers attend meetings of the Board and are
responsible for furnishing oral or written reports to keep the Board and
officers of IDEX fully informed as to the condition of the investments of each
fund, the investment recommendations of IMI, and the investment considerations
that have

                                       17


given rise to those recommendations. IMI supervises the purchase and sale of the
investments of each Fund and maintains all books and records required to be
maintained pursuant to the 1940 Act and the rules and regulations promulgated
thereunder with respect to transactions on behalf of IDEX.

The Investment Advisory Agreement contemplates that IMI, in connection with the
performance of its responsibilities under the Agreement, will enter into
sub-advisory agreements with sub-advisers to provide each Fund with investment
management services. IMI selects a sub-adviser based on a qualitative and
quantitative evaluation of the proposed sub-adviser. IMI monitors the
performance of each sub-adviser and evaluates how well the sub-adviser has
performed in managing the assets of its respective fund(s) in light of each such
fund's stated investment objective and policies. IMI also monitors each
sub-adviser's long-term performance and the level of risk assumed in achieving
that level of performance. Particular criteria for the selection and retention
of a sub-adviser include the sub-adviser's discipline and thoroughness in
pursuit of a fund's stated investment objective and the sub-adviser's long-term
performance. Short-term performance by itself is not a significant factor in
selecting or terminating a sub-adviser.

IMI also may, from time to time, recommend that the services of a sub-adviser be
terminated. The criteria for termination includes the departure of a
sub-adviser's key investment advisory personnel, a change in control of
management of the sub-adviser, a departure from a fund's stated investment
objective or policies, or other developments relating to the sub-adviser that
are deemed not to be in the best interest of shareholders by IMI.

THE SUB-ADVISERS

With respect to each Fund, IMI has entered into an investment sub-advisory
agreement (each a "Sub-Advisory Agreement" and, together, the "Sub-Advisory
Agreements") with one or more investment sub-advisers for each fund (each, a
"Sub-Adviser"). IDEX currently has 18 different sub-advisers. Each fund
currently has one sub-adviser. Each sub-adviser provides investment advisory
assistance and portfolio management advice to IMI for each Fund(s) with respect
to which the sub-adviser is engaged. Subject to review and supervision by IMI
and the Board, each sub-adviser is responsible for the actual investment
management of its fund(s) and for making decisions to buy, sell, or hold any
particular security. Each sub-adviser also places orders to buy or sell
securities on behalf of that fund. Each sub-adviser bears all of its expenses in
connection with the performance of its services, such as compensating and
furnishing office space for its officers and employees connected with investment
and economic research, trading, and investment management of its fund(s). Each
sub-adviser is a registered investment adviser under the Advisers Act. Each
sub-adviser receives monthly compensation from IMI based on a specified
percentage of the average daily net assets of each fund managed by that
sub-adviser.

Each sub-adviser has been recommended by IMI, and selected and approved by the
Board, including a majority of Trustees who are not parties to the sub-advisory
agreements or interested persons (within the meaning of Section 2(a)(19) of the
1940 Act) of any such party ("Disinterested Trustees"), as well as by the
shareholders of the relevant fund. The Sub-Advisory Agreement for each Fund was
approved on _______.

As required by the 1940 Act, each sub-advisory agreement: describes the
compensation that is to be paid to each sub-adviser by IMI; continues in effect
for up to two years and from year to year thereafter, only so long as such
continuance is specifically approved at least annually by the Board or by a vote
of the majority of the outstanding voting securities of the appropriate fund in
the manner required by the 1940 Act, and Rules thereunder; may be terminated at
any time, without the payment of any penalty, by the IDEX Board or by
shareholders on sixty (60) days' written notice to the Sub-Adviser, on (60)
days' written notice from IMI to the sub-adviser provided certain conditions are
met, or on sixty (60) days' written notice from the sub-adviser to the
investment adviser; will terminate automatically in the event of its assignment;
and requires approval of amendments thereto as specified by the 1940 Act.

The Section 15 Exemptive Order

On August 5, 1998, the SEC granted an exemption from Section 15(a) of the 1940
Act and Rule 18f-2 under the 1940 Act to AEGON/Transamerica Series Fund, Inc.
(formerly, WRL Series Fund, Inc.), AEGON/Transamerica Fund Advisers, Inc.
(formerly, WRL Investment Management, Inc.) (the "ATSF Adviser") and any other
registered investment company advised by the Adviser, or a person controlling,
controlled by, or under common control with

                                       18


the ATSF Adviser (ICI Release No. 23379) (the "Exemptive Order"). IDEX and IMI
are affiliates with those entities and are under common control with the
Adviser. The provisions of the 1940 Act require that shareholders approve
investment advisory agreements, including sub-advisory agreements, and to
approve any material amendment to such an investment advisory agreement. The
Exemptive Order was granted by the SEC on [DATE]. If shareholders approve the
Sub-Adviser Approval Policy as described in the Exemptive Order, IMI will be
authorized, subject to approval by the Board, to evaluate, select and retain new
sub-adviser each Funds, or materially amend an existing sub-advisory agreement
without obtaining further approval of the affected Funds' shareholders, whenever
the Investment Adviser and the Board believe such actions are in the best
interests of a Fund and its shareholders.

Current Sub-Adviser Approval Process. Currently, for each Fund, IMI enters into
a separate sub-advisory agreement with the respective sub-adviser selected by
the investment adviser and approved by the Board. Under the terms of these
sub-advisory agreements, the sub-advisers have authority to provide the
respective fund(s) with advice concerning the investment management of a fund's
assets. Subject to a fund's investment objective policies and restrictions, the
sub-advisers determine what securities shall be purchased or sold, and what
portion of a fund's assets shall remain uninvested. For these sub-advisory
services to each of the Funds, IMI pays each sub-adviser a monthly fee at an
annual rate based on the average daily net assets of each Fund, as specified in
the specific sub-advisory agreement. Each sub-adviser bears its own expenses of
providing sub-advisory services to the respective fund. Each fund's sub-advisory
agreement are subject to annual approval by the Board, including the
Disinterested Trustees. Any material amendments to an existing sub-advisory
agreement currently require approval by the Board and a fund's shareholders.

Each sub-adviser of a fund is an "investment adviser" to that fund, as that term
is defined in Section 2(a)(20) of the 1940 Act. Section 15(a) of the 1940 Act
and Rule 18f-2 thereunder provide, in effect, that it is unlawful for any person
to act as an investment adviser to a fund except pursuant to a written contract
that has been submitted to and approved by the vote of a majority of the voting
securities of that fund. Therefore, when a sub-adviser is initially retained,
shareholders of each affected fund generally are required to approve the
sub-advisory agreement with the proposed sub-adviser. Similarly, if an existing
sub-advisory agreement were amended in any material respect, such amendment
would generally be deemed to result in a new contract for which shareholder
approval would be required. Moreover, under Section 15(a), a sub-advisory
agreement terminates automatically upon its "assignment," which in most
instances would occur upon a change of control of the sub-adviser.

Proposed Sub-Adviser Approval Policy. Approval of the Sub-Adviser Approval
Policy on behalf of each Fund will not affect any of the requirements under the
federal securities laws that govern each Fund, the investment adviser, the
sub-advisers or the sub-advisory agreements other than the requirement to call
meetings of each Fund's shareholders and obtain approval for certain changes
affecting a non-affiliated sub-adviser. The Board, including the Disinterested
Trustees, will continue to evaluate and approve all new sub-advisory agreements
between the investment adviser and a sub-adviser as well as all changes to
existing sub-advisory agreements. IDEX and IMI will be subject to several
conditions imposed by the SEC to ensure that the interests of each Fund's
shareholders are adequately protected whenever IMI acts under the Sub-Adviser
Approval Policy. Furthermore, within 90 days of the hiring of a new sub-adviser,
IDEX will provide each Fund's shareholders with an information statement that
contains substantially the same information about the sub-adviser, the
sub-advisory agreement and the sub-advisory fee that would be required to be
sent to shareholders in a proxy statement.

SHAREHOLDER APPROVAL OF THIS PROPOSAL WILL NOT RESULT IN AN INCREASE OR DECREASE
IN THE TOTAL AMOUNT OF INVESTMENT ADVISORY FEES PAID BY EACH FUND TO IMI.
Shareholders should recognize that in engaging a new sub-adviser and entering
into a sub-advisory agreement, IMI will negotiate fees with that sub-adviser
and, because these fees are paid by IMI and not directly by each Fund, any fee
reduction negotiated by IMI may inure to IMI's benefit and any increase will
inure to its detriment. The fees paid to IMI by each Fund and the fees paid to a
sub-adviser by IMI are considered by the Board in approving the advisory and
sub-advisory arrangements, and any change in fees paid by each Fund to IMI would
require shareholder approval. In any event, if the shareholders approve this
Policy, then IMI, pursuant to each Fund's Investment Advisory Agreement, will
continue to provide the same level of management and administrative services to
each Fund as it has always provided.

                                       19


In addition to shareholder approval, the relief granted by the SEC and set forth
in the Exemptive Order is subject to the following conditions:

  (1)   IMI will not enter into a sub-advisory agreement with any affiliated
        sub-adviser without the sub-advisory agreement, including the
        compensation to be paid thereunder, being approved by each Fund's
        shareholders of that Fund.

  (2)   At all times, a majority of the Board will be persons each of whom is a
        Disinterested Trustee and the nomination of new or additional
        Disinterested Trustees will be within the discretion of the
        then-existing Disinterested Trustees.

  (3)   When a sub-adviser change is proposed for a Fund with an affiliated
        sub-adviser, the Board, including a majority of the Disinterested
        Trustees, will make a separate finding, reflected in the minutes of the
        meetings of the Board, that the change is in the best interests of each
        Fund and the shareholders. and does not involve a conflict of interest
        from which IMI or the affiliated sub-adviser derives an inappropriate
        advantage.

  (4)   IMI will provide general management and administrative services to IDEX
        and each Fund, including overall supervisory responsibility for the
        general management and investment of each Fund's securities portfolios,
        and subject to review and approval by the Board, will: (a) set each
        Fund's overall investment strategies; (b) select sub-advisers; (c)
        monitor and evaluate the performance of sub-advisers; (d) allocate and,
        when appropriate, reallocate each Fund's assets among its sub-advisers
        in those cases where each Fund has more than one sub-adviser; and (e)
        implement procedures reasonably designed to ensure that the sub-advisers
        comply with each Fund's investment objective, policies, and
        restrictions.

  (5)   Within ninety (90) days of the hiring of any new sub-adviser, IMI will
        furnish shareholders with all information about the new sub-adviser that
        would be included in a proxy statement. The information will include any
        change in the disclosure caused by the addition of a new sub-adviser.
        IMI will meet this condition by providing the shareholders with an
        information statement that meets certain requirements of the Securities
        Exchange Act of 1934, as amended, and the rules thereunder.

  (6)   IDEX will disclose in its prospectus the existence, substance, and
        effect of the Sub-Adviser Approval Policy. The IDEX prospectus will
        prominently disclose that the investment adviser has ultimate
        responsibility for the investment performance of each Fund due to its
        responsibility to oversee sub-advisers and recommend their hiring,
        termination, and replacement.

  (7)   No Trustee or officer of IDEX or IMI will own directly or indirectly
        (other than through a pooled investment vehicle that is not controlled
        by the Trustee or officer) any interest in a sub-adviser, except for:
        (a) ownership of interests in IMI or any entity that controls, is
        controlled by, or is under common control with IMI; or (b) ownership of
        less than one percent (1%) of the outstanding securities of any class of
        equity or debt securities of a publicly traded company that is either a
        sub-adviser or an entity that controls, is controlled by, or is under
        common control with a sub-adviser.

In addition, in connection with the implementation of the Sub-Adviser Approval
Policy, the Board and IMI may amend, from time to time, certain provisions of
the sub-advisory agreements to reflect the terms and conditions of the Exemptive
Order and the Sub-Adviser Approval Policy.

Reasons for Requesting Approval of the Sub-Adviser Approval Policy

The Board believes that providing IMI with maximum flexibility to perform those
duties that shareholders expect IMI to perform - selecting, supervising and
evaluating sub-advisers - without incurring the unnecessary delay or expense of
obtaining shareholder approval is in the best interests of each Fund's
shareholders because it will allow each Fund to operate more efficiently.
Currently, in order for IMI to appoint a sub-adviser or materially amend a
sub-advisory agreement, IDEX must call and hold a shareholders meeting of each
Fund, create and distribute proxy materials, and solicit proxy votes from each
Fund's shareholders. This process is time consuming and costly, and

                                       20


the costs are usually borne entirely by each Fund. Without the delay inherent in
holding a shareholders meeting, each Fund would be able to act more quickly and
with less expense to appoint a sub-adviser when the Trustees and IMI feel that
the appointment would benefit each Fund.

Also, the IDEX Board believes that it is appropriate to allow the selection,
supervision and evaluation of a sub-adviser to be done by IMI (subject to review
and approval by the IDEX Board) in light of the management structure of IDEX, as
well as IMI's significant experience and expertise in selecting sub-advisers and
the shareholders' expectation that IMI will utilize that expertise to select the
most competent sub-advisers. In the opinion of the Trustees, IMI has
demonstrated that it has the requisite expertise to evaluate, select and
supervise sub-advisers. The Board believes that many investors choose to invest
in a fund because of IMI's experience and expertise in evaluating and choosing
sub-advisers who can add the most value to a shareholder's investment in a fund.

Finally, the Board will provide sufficient oversight of the sub-adviser
selection process to ensure that shareholders' interests are protected whenever
IMI selects a new sub-adviser or materially amends an existing sub-advisory
agreements. The Board, including a majority of the Disinterested Trustees, will
continue to evaluate and approve all new sub-advisory agreements as well as any
amendments to existing sub-advisory agreements. In its review, the Board will
analyze all factors that it considers to be relevant to the determination,
including the nature, quality and scope of services provided by the sub-adviser.
The Trustees will compare the investment performance of the assets managed by
the sub-adviser with other accounts with similar investment objectives managed
by other advisers and will review the sub-adviser's compliance with federal
securities laws and regulations. The Board believes that their comprehensive
review will ensure that IMI continues to act in the best interests of each Fund
and its shareholders. Each sub-advisory agreement will continue to be subject to
all provisions of the 1940 Act, except for the specific provisions of the 1940
Act for which relief was granted by the SEC in the Exemptive Order.

Shareholder Approval

The adoption of the Sub-Adviser Approval Policy requires an affirmative vote of
a majority of outstanding shares present or by proxy. Shareholders of each Fund
will vote as separate classes on the proposals.

                                    EXHIBIT A
                      AGREEMENT AND PLAN OF REORGANIZATION

AGREEMENT AND PLAN OF REORGANIZATION dated _____ (the "Agreement") between IDEX
American Century International (the "Fund") and IDEX International Equity (the
"Acquiring Fund") of IDEX Mutual Funds ("IDEX"), a Massachusetts Business Trust.

This Agreement is intended to be and is adopted as a plan of reorganization and
liquidation within the meaning of Section 368(a)(1)(C) of the United States
Internal Revenue Code of 1986, as amended (the "Code"). The reorganization (the
"Reorganization") will consist of the transfer of all of the assets of each Fund
in exchange solely for shares of the Acquiring Fund and the assumption by the
Acquiring Fund of certain liabilities of each Fund and the distribution, after
the Closing Date hereinafter referred to, of the Acquiring Fund shares to the
shareholders of each Fund in liquidation of each Fund as provided herein, all
upon the terms and conditions hereinafter set forth in this Agreement.

WHEREAS, both each Fund and the Acquiring Fund are registered, diversified,
open-end management investment companies, and each Fund owns securities which
are assets of the character in which the Acquiring Fund is permitted to invest;

WHEREAS, both the Acquiring Fund and each Fund are authorized to issue their
shares of common stock;

WHEREAS, the Board of Trustees of IDEX has determined that the exchange of all
of the assets of each Fund and certain liabilities of each Fund for shares of
the Acquiring Fund and the assumption of such liabilities is in the best
interest of the Acquiring Fund's shareholders and that the interests of the
Acquiring Fund's existing shareholders would not be diluted as a result of this
transaction; and

WHEREAS, the Board of Trustees of IDEX has determined that the exchange of all
of the assets and certain of the liabilities of each Fund for shares of the
Acquiring Fund and the assumption of such liabilities is in the best interest of
each Fund's shareholders and that the interests of each Fund's existing
shareholders would not be diluted as a result of the transaction.

NOW THEREFORE, in consideration of the premises and covenants and agreements
hereinafter set forth, the parties agree as follows:

1.      TRANSFER OF ASSETS OF EACH FUND IN EXCHANGE FOR THE ACQUIRING FUND
        SHARES AND ASSUMPTION OF FUND LIABILITIES AND LIQUIDATION OF EACH FUND.

        1.1    Subject to the terms and conditions contained herein, each Fund
               agrees to assign, transfer and convey to the Acquiring Fund all
               of the assets of each Fund, including all securities and cash
               (subject to liabilities), and the Acquiring Fund agrees in
               exchange therefor (i ) to deliver to each Fund the number of
               Acquiring Fund shares, including fractional Acquiring Fund
               shares, determined as set forth in paragraph 2.3; and (ii) to
               assume certain liabilities of each Fund, as set forth in
               paragraph 1.2. Such transactions shall take place at the closing
               (the "Closing") on the closing date ("Closing Date") provided for
               in paragraph 3.1. In lieu of delivering certificates for the
               Acquiring Fund shares, the Acquiring Fund shall credit the
               Acquiring Fund shares to each Fund's account on the books of the
               Acquiring Fund and shall deliver a confirmation thereof to each
               Fund.

        1.2    Each Fund will endeavor to discharge all of its know liabilities
               and obligations prior to the Closing Date. The Acquiring Fund
               shall assume all liabilities, expenses, costs, charges and
               reserves reflected on an unaudited statement of assets and
               liabilities of each Fund prepared by IDEX, as of the Valuation
               Date (as defined in paragraph 2.1), in accordance with generally
               accepted accounting principles consistently applied from the
               prior audited period. The Acquiring Fund shall assume only those
               liabilities of each Fund reflected in that unaudited statement of
               assets and liabilities and shall not assume any other
               liabilities, whether absolute or contingent.

                                       1


        1.3    Delivery of the assets of each Fund to be transferred shall be
               made on the Closing Date and shall be delivered to State Street
               Bank, the IDEX custodian (the "Custodian"), for the account of
               the Acquiring Fund, with all securities not in bearer or
               book-entry form duly endorsed, or accompanied by duly executed
               separate assignments or stock powers, in proper form for
               transfer, with signatures guaranteed, and with all necessary
               stock transfer stamps, sufficient to transfer good and marketable
               title thereto (including all accrued interest and dividends and
               rights pertaining thereto) to the Custodian for the account of
               the Acquiring Fund free and clear of all liens, emcumbrances,
               rights, restrictions and claims. All cash delivered shall be in
               the form of immediately available funds payable to the order of
               the Custodian for the account of the Acquiring Fund.

        1.4    Each Fund will pay or cause to be paid to the Acquiring Fund any
               interest received on or after the Closing Date with respect to
               assets transferred to the Acquiring Fund hereunder. Each Fund
               will transfer to the Acquiring Fund any distributions, rights or
               other assets received by each Fund after the Closing Date as
               distributions on or with respect to the securities transferred.
               Such assets shall be deemed included in assets transferred to the
               Acquiring Fund on the Closing Date and shall not be separately
               valued.

        1.5    As soon after the Closing Date as is conveniently practicable
               (the "Liquidation Date"), each Fund will liquidate and distribute
               pro rata to each Fund's shareholders of record, determined as of
               the close of business on the Closing Date, Acquiring Fund shares
               received by each Fund pursuant to paragraph 1.1. Such liquidation
               and distribution will be accomplished by the transfer of the
               applicable Acquiring Fund shares then credited to the account of
               each Fund on the books of the Acquiring Fund to open accounts on
               the share records of the Acquiring Fund in the names of each
               Fund's shareholders and representing the respective pro rata
               number of the applicable Acquiring Fund shares due such
               shareholders. All issued and outstanding shares of each Fund
               simultaneously will be canceled on the books of each Fund.

        1.6    Ownership of Acquiring Fund shares will be shown on the books of
               the Acquiring Fund's transfer agent. Shares of the Acquiring Fund
               will be issued in the manner described in the IDEX current
               prospectus and statement of additional information.

        1.7    Any transfer taxes payable upon issuance of the Acquiring Fund
               shares in a name other than the registered holder of the
               Acquiring Fund shares on the books of each Fund as of that time
               shall, as a condition of such issuance and transfer, be paid by
               the person to whom such Acquiring Fund shares are to be issued
               and transferred.

        1.8    Any reporting responsibility of each Fund is and shall remain the
               responsibility of each Fund up to and including the Closing Date
               and such later date on which each Fund is dissolved.

         2.    VALUATION.

        2.1    The value of each Fund's assets to be acquired by the Acquiring
               Fund hereunder shall be the value of such assets computed as of
               the close of trading on the floor of the New York Stock Exchange
               (currently, 4:00 p.m., New York time), except that options and
               futures contracts will be valued 15 minutes after the close of
               trading on the floor of the New York Stock Exchange, on the
               Closing Date (such time and date being hereinafter called the
               "Valuation Date"),using the valuation procedures set forth in the
               IDEX Declaration of Trust, as amended, (the "IDEX Charter"), and
               then-current prospectus or statement of additional information.
               In no event shall the same security held by both each Fund and
               the Acquiring Fund be valued at different prices.

        2.2    The net asset value of an Acquiring Fund share shall be the net
               asset value per share computed as of the Valuation Date, using
               the valuation procedures set forth in the Acquiring Fund's
               Charter and then-current prospectus or statement of additional
               information.

                                       2


        2.3    The number of Acquiring Fund shares to be issued (including
               fractional shares, if any) in exchange for each Fund's net assets
               shall be determined by dividing the value of the net assets of
               each Fund determined using the same valuation procedures referred
               to in paragraph 2.1 by the net asset value of one Acquiring Fund
               share, determined in accordance with paragraph 2.2.

        2.4    All computations of value shall be made in accordance with the
               regular practices of the Acquiring Fund.

        3.     CLOSING AND CLOSING DATE.

        3.1    The Closing Date shall be February 28, 2001 or such later date as
               the parties may mutually agree. All acts taking place at the
               Closing shall be deemed to take place simultaneously as of the
               close of business on the Closing Date unless otherwise provided.
               The Closing shall be held at 5:00 p.m., New York time, at the
               offices of IDEX, 570 Carillon Parkway, St. Petersburg, Florida
               33716 or such other time and/or place as the parties may mutually
               agree.

        3.2    The Custodian shall deliver at the Closing a certificate of an
               authorized officer stating that: (a) each Fund's portfolio
               securities, cash and any other assets have been delivered in
               proper form to the Acquiring Fund within two business days prior
               to or on the Closing Date; and (b) all necessary taxes including
               all applicable stock transfer stamps have been paid, or provision
               for payment shall have been made, in conjunction with the
               delivery of portfolio securities.

        3.3    If on the Valuation Date (a) the New York Stock Exchange or
               another primary trading market for portfolio securities of the
               Acquiring Fund or each Fund shall be closed to trading or trading
               thereon shall be restricted, or (b) trading or the reporting of
               trading on said Exchange or elsewhere shall be disrupted so that
               accurate appraisal of the value of the net assets of the
               Acquiring Fund or each Fund is impracticable, the Closing Date
               shall be postponed until the first business day after the day
               when trading shall have been fully resumed and reporting shall
               have been restored.

        3.4    The transfer agent for each Fund shall deliver at the Closing a
               certificate of an authorized officer stating that its records
               contain the names and addresses of each Fund's shareholders and
               the number and percentage ownership of outstanding shares,
               respectively, owned by each such shareholder immediately prior to
               the Closing. The Acquiring Fund shall issue and deliver a
               confirmation evidencing the Acquiring Fund shares to be credited
               on the Closing Date to the Secretary of each Fund, or provide
               evidence satisfactory to each Fund that such Acquiring Fund
               shares have been credited to each Fund's account on the books of
               the Acquiring Fund. At the Closing, each party shall deliver to
               the other such bills of sale, checks, assignments, receipts or
               other documents as such other party or its counsel may reasonably
               request.

        4.     REPRESENTATIONS AND WARRANTIES.

        4.1    Each Fund represents and warrants to the Acquiring Fund as
               follows:

               (a) Each Fund is a series of IDEX Mutual Funds, in a
               Massachusetts Business Trust duly organized and validly existing
               under the laws of the State of Massachusetts and has power to own
               all of its properties and assets and to carry out its obligations
               under this Agreement.

               (b) Each Fund is registered under the Investment Company Act of
               1940, as amended (the "1940 Act"), as a open-end, diversified,
               management investment company, and such registration has not been
               revoked or rescinded and is in full force and effect.

               (c) Each Fund is not, and the execution, delivery and performance
               of this Agreement will not result, in material violation of the
               IDEX Declaration of Trust, as amended (the "Funds' Charter"), or
               its Bylaws or of any agreement, indenture, instrument, contract,
               lease or other undertaking to which each Fund is a party or by
               which it is bound.

                                       3


               (d) Each Fund has no material contracts or other commitments
               outstanding (other than this Agreement) which will be terminated
               with liability to it on or prior to the Closing Date.

               (e) No litigation or administrative proceeding or investigation
               of or before any court or governmental body is currently pending
               or to its knowledge threatened against each Fund or any of its
               properties or assets which, if adversely determined, would
               materially and adversely affect its financial condition or the
               conduct of its business. Each Fund knows of no facts which might
               form the basis for the institution of such proceedings, and is
               not a party to or subject to the provisions of any order, decree
               or judgment of any court or governmental body which materially
               and adversely affects its business or its ability to consummate
               the transactions herein contemplated.

               (f) The Statements of Assets and Liabilities of each Fund dated
               ________, 2001, have not been audited as each Fund commenced
               operation in April 2001. The unaudited statement (copies of which
               have been furnished to the Acquiring Fund) fairly reflect the
               financial condition of each Fund as of such dates, and there are
               no known contingent liabilities of each Fund as of such dates not
               disclosed therein.

               (g) Since _____, 2001, there has not been any material adverse
               change in each Fund's financial condition, assets, liabilities or
               business other than changes occurring in the ordinary course of
               business, or any incurrence by each Fund of indebtedness maturing
               more than one year from the date such indebtedness was incurred,
               except as disclosed on the statement of assets and liabilities
               referred to in Section 1.2 hereof.

               (h) At the Closing Date, all Federal and other tax returns and
               reports of each Fund required by law to have been filed by such
               dates shall have been filed, and all Federal and other taxes
               shall have been paid so far as due, or provision shall have been
               made for the payment thereof, and to the best of each Fund's
               knowledge no such return is currently under audit and no
               assessment has been asserted with respect to such returns.

               (i) Each Fund intends to meet, and to continue to meet, the
               requirements of Subchapter M of the Code for qualification and
               treatment as a regulated investment company.

               (j) All issued and outstanding shares of each Fund are, and at
               the Closing Date will be, duly and validly issued and
               outstanding, fully paid and non-assessable. All of the issued and
               outstanding shares of each Fund will, at the time of Closing, be
               held by the persons and in the amounts set forth in the records
               of the transfer agent as provided in paragraph 3.4. Each Fund
               does not have outstanding any options, warrants or other rights
               to subscribe for or purchase any of each Fund shares, nor is
               there outstanding any security convertible into any of each Fund
               shares.

               (k) On the Closing Date, each Fund will have full right, power
               and authority to sell, assign, transfer and deliver the assets to
               be transferred by it hereunder.

               (l) The execution, delivery and performance of this Agreement
               will have been duly authorized prior to the Closing Date by all
               necessary action on the part of the IDEX Board of Trustees and,
               subject to the approval of shareholders of each Fund, this
               Agreement will constitute the valid and legally binding
               obligation of each Fund, enforceable in accordance with its
               terms, subject to the effect of bankruptcy, insolvency,
               reorganization, moratorium, fraudulent conveyance and other
               similar laws relating to or affecting creditors' rights generally
               and court decisions with respect thereto, and to general
               principles of equity and the discretion of the court (regardless
               of whether the enforceability is considered in a proceeding in
               equity or at law).

               (m) The proxy statement of each Fund (the "Proxy Statement"),
               included in the Registration Statement referred to in paragraph
               5.5 (other than information therein that has been furnished by
               the Acquiring Fund) will, on the effective date of the
               Registration Statement and on the Closing Date, not contain any
               untrue statement of a material fact or omit to state a material
               fact required to

                                       4


               be stated therein or necessary to make the statements therein, in
               light of the circumstances under which such statements were made,
               not materially misleading.

        4.2    The Acquiring Fund represents and warrants as follows:

               (a) The Acquiring Fund is a series of IDEX Mutual Funds duly
               organized and validly existing under the laws of the State of
               Massachusetts and has power to carry on its business as it is now
               being conducted and to carry out its obligations under this
               Agreement.

               (b) The Acquiring Fund is registered under the 1940 Act as an
               open-end, diversified management investment company, and such
               registration has not been revoked or rescinded and is in full
               force and effect.

               (c) The current prospectus and statement of additional
               information of the Acquiring Fund conform in all material
               respects to the applicable requirements of the Securities Act of
               1933, as amended (the "1933 Act"), and the 1940 Act and the rules
               and regulations of the Securities and Exchange Commission
               thereunder and do not include any untrue statement of a material
               fact or omit to state any material fact required to be stated
               therein or necessary to make the statements therein, in light of
               the circumstances under which they were made, not materially
               misleading.

               (d) The Acquiring Fund is not, and the execution, delivery and
               performance of this Agreement will not result, in material
               violation of the IDEX Charter or its Bylaws or of any agreement,
               indenture, instrument, contract, lease or other undertaking to
               which the Acquiring Fund is a party or by which it is bound.

               (e) No litigation or administrative proceeding or investigation
               of or before any court or governmental body is currently pending
               or to its knowledge threatened against the Acquiring Fund or any
               of its properties or assets which, if adversely determined, would
               materially and adversely affect its financial condition or the
               conduct of its business. The Acquiring Fund knows of no facts
               which might form the basis for the institution of such
               proceedings, and is not a party to or subject to the provisions
               of any order, decree or judgment of any court or governmental
               body which materially and adversely affects its business or its
               ability to consummate the transactions contemplated herein.

               (f) The Statements of Assets and Liabilities of the Acquiring
               Fund for the period ending October 31, 2000 were taken from the
               audited IDEX Mutual Funds by the firm of PricewaterhouseCoopers,
               LLP and are in accordance with generally accepted accounting
               principles, consistently applied, and such statements (copies of
               which have been furnished to each Fund) fairly reflect the
               financial condition of the Acquiring Fund as of such dates.

               (g) Since October 31, 2000 there has not been any material
               adverse change in the Acquiring Funds' financial condition,
               assets, liabilities or business other than changes occurring in
               the ordinary course of business, or any incurrence by the
               Acquiring Fund of indebtedness maturing more than one year from
               the date such indebtedness was incurred, except as disclosed on
               the statement of assets and liabilities referred to in Section
               4.2(f) hereof.

               (h) At the Closing Date, all Federal and other tax returns and
               reports of the Acquiring Fund required by law then to be filed
               shall have been filed, and all Federal and other taxes shown as
               due on said returns and reports shall have been paid or provision
               shall have been made for the payment thereof.

               (i) For each fiscal year of its operation, the Acquiring Fund has
               met the requirements of Subchapter M of the Code for
               qualification and treatment as a regulated investment company.

               (j) All issued and outstanding shares of the Acquiring Fund are,
               and at the Closing Date will be, duly and validly issued and
               outstanding, fully paid and non-assessable. The Acquiring Fund
               does not have outstanding any options, warrants or other rights
               to subscribe for or purchase any of the

                                       5


               Acquiring Funds' shares, nor is there outstanding any security
               convertible into any Acquiring Fund shares.

               (k) The execution, delivery and performance of this Agreement
               will have been duly authorized prior to the Closing Date by all
               necessary action on the part of the Acquiring Fund's Board of
               Trustees, and this Agreement will constitute the valid and
               legally binding obligation of the Acquiring Fund enforceable in
               accordance with its terms, subject to the effect of bankruptcy,
               insolvency, reorganization, moratorium, fraudulent conveyance and
               other similar laws relating to or affecting creditors' rights
               generally and court decisions with respect thereto, and to
               general principles of equity and the discretion of the court
               (regardless of whether the enforceability is considered in a
               proceeding in equity or at law).

               (l) The Proxy Statement included in the Registration Statement
               (only insofar as it relates to the Acquiring Fund and is based on
               information furnished by the Acquiring Fund) will, on the
               effective date of the Registration Statement and on the Closing
               Date, not contain any untrue statement of a material fact or omit
               to state a material fact required to be stated therein or
               necessary to make the statements therein, in light of the
               circumstances under which such statements were made, not
               materially misleading.

5.      COVENANTS OF THE ACQUIRING FUND AND EACH FUND.

        5.1 The Acquiring Fund and each Fund each will operate its business in
        the ordinary course between the date hereof and the Closing Date, it

        which will be carried over to the Acquiring Fund as a result of Section
        381 of the Code and which will be certified by each Fund's President or
        its Vice President and Treasurer.

        appropriate in order to continue its operations after the Closing Date.

        Closing Date, except as they may be affected by the transactions
        contemplated by this Agreement, and as to such other matters as the
        Acquiring Fund shall reasonably request.

7.      CONDITIONS PRECEDENT TO OBLIGATIONS OF EACH FUND.

8.      FURTHER CONDITIONS PRECEDENT TO OBLIGATIONS OF THE ACQUIRING FUND AND
        EACH FUND.

If any of the conditions set forth below do not exist on or before the Closing
Date with respect to each Fund or the Acquiring Fund, the other party to this
Agreement shall, at its option, not be required to consummate the transactions
contemplated by this Agreement.

        8.1 This Agreement and the transactions contemplated herein shall have
        been approved by the requisite vote of the holders of the outstanding
        shares of each Fund in accordance with the provisions of the IDEX

        each Fund to permit consummation, in all material respects, of the
        transactions contemplated hereby shall have been obtained, except where
        failure to obtain any such consent, order or permit would not involve a
        risk of a material adverse effect on the assets or properties of the
        Acquiring Fund or each Fund, provided that either party hereto may for
        itself waive any of such conditions.

                                       7


        8.4 The Registration Statement shall have become effective under the
        1933 Act and no stop orders suspending the effectiveness thereof shall
        have been issued and, to the best knowledge of the parties hereto, no

        or be pending, threatened or contemplated under the 1933 Act.

        8.5 Each Fund shall have declared a dividend or dividends which,
        together with all previous such shall have the effect of distributing to
        each Fund's shareholders all of each Fund's investment company taxable
        income for all taxable years or periods ending on or prior to the
        Closing Date (computed without regard to any deduction for dividends
        paid); the excess of its interest income excludable from gross income
        under Section 103(a) of the Code over its disallowed deductions under
        Sections 265 and 171(a)(2) of the Code, for all taxable years or periods
        ending on or prior to the Closing Date; and all of its net capital gain
        realized in all taxable years or periods ending on or prior to the
        Closing Date (after reduction for any capital loss carry forward).

        8.6 The parties shall have received an opinion of Sutherland Asbill &
        Brennan LLP substantially to the effect that for Federal income tax
        purposes:

        (a) The transfer of all or substantially all of each Fund's assets in
        exchange for the Acquiring Fund shares and the assumption by the
        Acquiring Fund of certain identified liabilities of each Fund will
        constitute a "reorganization" within the meaning of Section 368(a)(1)(C)
        of the Code; (b) No gain or loss will be recognized by the Acquiring
        Fund upon the receipt of the assets of each Fund solely in exchange for
        the Acquiring Fund shares and the assumption by the Acquiring Fund of
        certain identified liabilities of each Fund; (c) No gain or loss will be
        recognized by each Fund upon the transfer of each Fund's assets to the
        Acquiring Fund in exchange for the Acquiring Fund shares and the
        assumption by the Acquiring Fund of certain identified liabilities of
        each Fund or upon the distribution (whether actual or constructive) of
        the Acquiring Fund shares to Fund shareholders in exchange for their
        shares of each Fund; (d) No gain or loss will be recognized by Fund
        shareholders upon the exchange of their Fund shares for the Acquiring
        Fund shares; (e) The aggregate tax basis for the Acquiring Fund shares
        received by each of each Fund's shareholders pursuant to the
        Reorganization will be the same as the aggregate tax basis of each Fund
        shares held by such shareholder immediately prior to the Reorganization,
        and the holding period of the Acquiring Fund shares to be received by
        each Fund shareholder will include the period during which each Fund
        shares exchanged therefor were held by such shareholder (provided each
        Fund shares were held as capital assets on the date of the
        Reorganization); and (f) The tax basis of each Fund assets acquired by
        the Acquiring Fund will be the same as the tax basis of such assets to
        each Fund immediately prior to the Reorganization, and the holding
        period of the assets of each Fund in the hands of the Acquiring Fund
        will include the period during which those assets were held by each
        Fund.

        No opinion will be expressed as to the effect of the Reorganization on
(i) each Fund or the Acquiring Fund with respect to any asset as to which any
unrealized gain or loss is required to be recognized for Federal income tax
purposes at the end of a taxable year (or on the termination or transfer
thereof) under a mark-to-market system of accounting, and (ii) any shareholder
of each Fund that is required to recognize unrealized gains and losses for
Federal income tax purposes under a mark-to-market system of accounting.

9.      TERMINATION OF AGREEMENT.

        9.1 This Agreement and the transaction contemplated hereby may be
        terminated and abandoned by resolution of the Board of each Fund or of
        the Acquiring Fund, as the case may be, at any time prior to the Closing
        Date (and notwithstanding any shareholder vote) if circumstances should
        develop that, in the opinion of either Board, make proceeding with the
        Agreement inadvisable.

        9.2 If this Agreement is terminated and the transaction contemplated
        hereby is abandoned pursuant to the provisions of this Section 9, this
        Agreement shall become void and have no effect, without any liability on
        the part of any party hereto or the directors, officers or shareholders
        of the Acquiring Fund or of each Fund, as the case may be, in respect of
        this Agreement, except that the parties shall bear the aggregate
        expenses of

                                       8


        the transaction contemplated hereby in proportion to their respective
        net assets as of the date this Agreement is terminated or the exchange
        contemplated hereby is abandoned.

10.     WAIVER.

At any time prior to the Closing Date, any of the foregoing conditions may be
waived by the IDEX Board on behalf of each Fund or of the Acquiring Fund if, in
its judgment of either, such waiver will not have a material adverse effect on
the benefits intended under this Agreement to the shareholders of each Fund or
of the Acquiring Fund, as the case may be.

11.     MISCELLANEOUS.

        11.1 None of the representations and warranties included or provided for
        herein shall survive consummation of the transactions contemplated
        hereby.

        11.2 This Agreement contains the entire agreement and understanding
        between the parties hereto with respect to the subject matter hereof,
        and merges and supersedes all prior discussions, agreements and
        understandings of every kind and nature between them relating to the
        subject matter hereof. Neither party shall be bound by any condition,
        definition, warranty or representation, other than as set forth or
        provided in this Agreement or as may be, on or subsequent to the date
        hereof, set forth in a writing signed by the party to be bound thereby.

        11.3 This Agreement shall be governed and construed in accordance with
        the internal laws of the State of Florida, without giving effect to
        principles of conflict of laws; provided, however, that the due
        authorization, execution and delivery of this Agreement by each Fund and
        the Acquiring Fund shall be governed and construed in accordance with
        the internal laws of the State of Massachusetts without giving effect to
        principles of conflict of laws.

        11.4 This Agreement may be executed in counterparts, each of which, when
        executed and delivered, shall be deemed to be an original.

        11.5 This Agreement shall bind and inure to the benefit of the parties
        hereto and their respective successors and assigns, but no assignment or
        transfer hereof or of any rights or obligations hereunder shall be made
        by any party without the written consent of the other party. Nothing
        herein expressed or implied is intended or shall be construed to confer
        upon or give any person, firm or corporation, other than the parties
        hereto and their respective successors and assigns, any rights or
        remedies under or by reason of this Agreement.

                                       9


IN WITNESS WHEREOF, the Acquiring Fund and each Fund have caused this Agreement
and Plan of Reorganization to be executed and attested on its behalf by its duly
authorized representatives as of the date first above written.

                                  Dated: ______



This Statement of Additional Information, which is not a prospectus, supplements
and should be read in connection with the Prospectus/Proxy Statement dated
__________, relating specifically to the proposed transfer of all of the assets
and liabilities of IDEX Munder Net50, IDEX Transamerica Small Company and IDEX
Pilgrim Baxter Technology (each a "Fund," collectively, the "Funds") in exchange
for shares of IDEX Pilgrim Baxter Mid Cap Growth (the "Acquiring Fund"). The
transfer is to occur pursuant to an Agreement and Plan of Reorganization. Each
of the following documents accompanies this Statement of Additional Information
and is incorporated herein by reference.

        1.      The IDEX Prospectus and Statement of Additional Information
                dated March 1, 2001.

        2.      The IDEX Annual Report dated _______________.

        3.      The IDEX Semi-Annual Report dated __________.

                               GENERAL INFORMATION

This Statement of Additional Information relates to the proposed transfer of
substantially all of the assets and liabilities of the Funds to the Acquiring
Fund, in exchange for like shares of Acquiring Fund (the "Reorganization" or the
"Exchange"). The aggregate net asset value of each share issued will have an
aggregate net asset value equal to the aggregate net asset value of the shares
of each Fund that were outstanding immediately before the effective time of the
Reorganization.

        After the transfer of substantially all of its assets and liabilities in
exchange for the Acquiring Fund, each Fund will distribute such shares to its
shareholders in liquidation of each Fund. Each shareholder owning shares of each
Fund at the effective time of the Reorganization will receive shares of the same
Class from the Acquiring Fund of equal value, and will receive any unpaid
dividends or distributions that were declared before the effective time of the
Reorganization on shares of each Fund. The Acquiring Fund will establish an
account for each former shareholder of each Fund reflecting the appropriate
number of shares distributed to such shareholder. These accounts will be
substantially identical to the accounts maintained by each Fund for each
shareholder. Upon completion of the Reorganization with respect to each Fund,
all outstanding shares of each Fund will have been redeemed and cancelled in
exchange for shares distributed by the Acquiring Fund, and each Fund will wind
up its affairs and be terminated as a series of IDEX under Massachusetts law.

For further information about the transaction, see the Proxy Statement/

Item 15.  Indemnification

Reference is made to ________ of the Registrant's Declaration of Trust, _____ of
the Registrant's By-Laws and Section ___ of the Distribution Agreements between
IDEX and AFSG Securities Corporation.

Insofar as indemnification for liabilities arising under the Securities Act of
1933, as amended (the "Securities Act"), may be permitted to Trustees, officers
and controlling persons of the Registrant pursuant to the foregoing provisions,
or otherwise, the Registrant understands that in the opinion of the Securities
and Exchange Commission ("SEC") such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable.

In the event that a claim for indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by a Trustee,
officer or controlling person of the 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, the 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
Securities Act and will be governed by the final adjudication of such issue.
