Dear Shareholder:

The Board of Directors ("Board") has called a special meeting of shareholders of
Security Cash Fund (the "Acquired Fund") to be held on June 19, 2009 at 1:00
p.m. Central time, or any adjournment(s) or postponement(s) thereof (the
"Special Meeting"), at the executive offices of Security Cash Fund, One Security
Benefit Place, Topeka, Kansas 66636-0001. The Board has called the Special
Meeting so that shareholders can vote on a proposed Agreement and Plan of
Reorganization ("Reorganization Plan") regarding the Acquired Fund, as discussed
below.

Management of the Acquired Fund has recommended that the Board approve the
Reorganization Plan relating to the reorganization of the Acquired Fund into
U.S. Government Money Market Fund (the "Acquiring Fund"), a series of Rydex
Series Funds (the "Reorganization"). The Reorganization will permit Acquired
Fund shareholders to become shareholders of the Acquiring Fund and to pursue
similar investment goals in a substantially larger fund that has a similar
investment objective and comparable performance record as the Acquired Fund. The
Acquiring Fund, like the Acquired Fund, is a money market fund that seeks to
maintain a stable share price of $1.00 such that the value of your shares in the
Acquired Fund prior to the Reorganization will be the same as the value of your
shares in the Acquiring Fund after the Reorganization. Also, the Acquiring Fund
is part of the Rydex family of funds, which is managed by an investment adviser
affiliated with the investment adviser managing the Security Funds. After the
Reorganization, shareholders of the Acquired Fund will be able to exchange their
new shares of the Acquiring Fund for shares of any Security Fund as they have
been able to do as shareholders of the Acquired Fund, and it is expected that
some time after the Reorganization, they will also be able to exchange their
shares for shares of other mutual funds distributed by Rydex Distributors, Inc.
(the "Rydex Funds").

Management believes that the Reorganization should enable Acquired Fund
shareholders to benefit from more efficient portfolio management and will
eliminate the duplication of resources and costs associated with servicing the
Acquired Fund and the Acquiring Fund separately within related families of
mutual funds.

After careful consideration, the Board has unanimously approved this proposal
with respect to the Acquired Fund and recommends that shareholders of the
Acquired Fund vote "FOR" the proposal. Accordingly, you are asked to authorize
the Reorganization.

A Proxy Statement/Prospectus that describes the Reorganization is enclosed. We
urge you to vote your shares by completing and returning the enclosed proxy in
the envelope provided, or vote by Internet or telephone, at your earliest
convenience.

YOUR VOTE IS IMPORTANT REGARDLESS OF THE NUMBER OF SHARES YOU OWN. IN ORDER TO
AVOID THE ADDED COST OF FOLLOW-UP SOLICITATIONS AND POSSIBLE ADJOURNMENTS,
PLEASE TAKE A FEW MINUTES TO READ THE PROXY STATEMENT/PROSPECTUS AND CAST YOUR
VOTE. IT IS IMPORTANT THAT YOUR VOTE BE RECEIVED NO LATER THAN 11:59 P.M.
CENTRAL TIME ON JUNE 18, 2009.

We appreciate your participation and prompt response in this matter and thank
you for your continued support.

                                                                      Sincerely,

                                                          /s/ Richard M. Goldman

               PROPOSED REORGANIZATION OF SECURITY CASH FUND INTO
        U.S. GOVERNMENT MONEY MARKET FUND, A SERIES OF RYDEX SERIES FUNDS

                              QUESTIONS AND ANSWERS

The enclosed materials include a Proxy Statement/Prospectus containing
information you need to make an informed decision about the proposed
reorganization. However, we thought it also would be helpful to begin by
answering some of the important questions you might have about the proposal. The
matters discussed below are also discussed in more detail in the enclosed Proxy
Statement/Prospectus.

WHAT ISSUE AM I BEING ASKED TO VOTE ON AT THE UPCOMING SPECIAL MEETING ON JUNE
19, 2009?

Shareholders of Security Cash Fund (the "Acquired Fund") are being asked to
approve an Agreement and Plan of Reorganization that provides for the
reorganization (the "Reorganization" ) of the Acquired Fund into U.S. Government
Money Market Fund (the "Acquiring Fund" and together with the Acquired Fund, the
"Funds"), a series of Rydex Series Funds.

WHAT WILL HAPPEN TO MY SECURITY CASH FUND INVESTMENT IF THE PROPOSED
REORGANIZATION IS APPROVED? WHAT ARE THE RYDEX FUNDS?

You will become a shareholder of the Acquiring Fund on or about July 10, 2009
(the "Closing Date"), and will no longer be a shareholder of the Acquired Fund.
The Acquiring Fund currently issues four classes of shares: A Class, C Class,
Investor Class and Advisor Class and will start issuing and offering Investor2
Class shares in connection with the Reorganization. Investor2 Class is a class
of shares with characteristics very similar to the shares of the Acquired Fund
that you currently own, and that permit exchanges within the Security Funds. You
will receive Investor2 Class shares of the Acquiring Fund with a value equal to
the value of your investment in the Acquired Fund as of the Closing Date. The
Acquired Fund will then cease operations and be liquidated.

The Acquiring Fund is part of a fund complex managed by PADCO Advisors, Inc.,
which operates as Rydex Investments, which is controlled by Security Benefit
Corporation ("Security Benefit") which also controls the Acquired Fund's
investment adviser, Security Investors, LLC ("Security Investors"). As a result,
both the Acquired Fund and the Acquiring Fund are part of related families of
mutual funds. If the Reorganization is consummated, shareholders of the Acquired
Fund will continue to enjoy the same quality of support services that they have
enjoyed in the past as shareholders of Security Benefit funds and will continue
to be able to exchange their new shares of the Acquiring Fund for shares of any
Security Fund as they have been able to do as shareholders of the Acquired Fund.
Furthermore, it is expected that some time after the Reorganization, they will
also be able to exchange their shares for shares of other mutual funds
distributed by Rydex Distributors, Inc. (the "Rydex Funds").

WHAT HAPPENS IF THE REORGANIZATION IS NOT APPROVED?

If shareholders of the Acquired Fund do not approve the proposed reorganization,
the reorganization will not take effect and the Acquired Fund's Board of
Directors (the "Board") will determine what, if any, additional action should be
taken with respect to the Acquired Fund. Such action could include liquidation
of the Acquired Fund.

WHAT ARE THE BENEFITS OF THE PROPOSED REORGANIZATION FOR ME?

Both Funds are "money market funds" that seek to maintain a stable share price
of $1.00 and both Funds are managed by affiliated managers. The Board believes
that the reorganization will permit the Acquired Fund's shareholders to continue
to invest in a substantially larger money market fund with a similar investment
objective and policies. By combining the Acquired Fund with the Acquiring Fund,
which has substantially more assets than the Acquired Fund, the Acquired Fund's
shareholders could benefit from more efficient portfolio management and

                                       i


the Acquiring Fund's gross and net operating expense ratios, which have
historically been lower than those of the Acquired Fund (although there is no
guarantee that this trend will continue in the future).

DO THE FUNDS HAVE SIMILAR INVESTMENT OBJECTIVES AND STRATEGIES?

The Funds have similar investment objectives, although the Funds somewhat differ
in their principal investment strategies. The Acquired Fund seeks as high a
level of current income as is consistent with preservation of capital and
liquidity, and the Acquiring Fund seeks to provide security of principal, high
current income, and liquidity. Both Funds invest in money market instruments in
accordance with the terms of the U.S. Securities and Exchange Commission rules
for money market funds. As money market funds, the Funds are each subject to
maturity, quality and diversification requirements to help maintain a $1.00
share price. However, the Acquiring Fund invests primarily in money market
instruments issued or guaranteed as to principal and interest by the U.S.
government, its agencies or instrumentalities, and enters into repurchase
agreements fully collateralized by U.S. government securities while the Acquired
Fund invests primarily in money market instruments of non-governmental issuers
rated in the two highest credit rating categories.

WHAT ARE THE DIFFERENCES IN THE MANAGEMENT OF THE FUNDS?

The Acquired Fund is managed by Security Investors and the Acquiring Fund is
managed by Rydex Investments. Security Investors and Rydex Investments are
affiliated with each other. The Funds are managed by different portfolio
managers and have different board members.

WILL THE PROPOSED REORGANIZATION RESULT IN A HIGHER MANAGEMENT FEE OR HIGHER
FUND EXPENSES?

The Acquired Fund and the Acquiring Fund each pay Security Investors and Rydex
Investments, respectively, a management fee at the annual rate of 0.50% of the
value of the respective Fund's average daily net assets. The Acquiring Fund's
historical gross and net operating expense ratios were lower than those of the
Acquired Fund, although there is no guarantee that this trend will continue in
the future.

WHAT ARE THE TAX CONSEQUENCES OF THE PROPOSED REORGANIZATION?

The reorganization is not expected to be a taxable event for federal income tax
purposes. Shareholders are not expected to recognize any capital gain or loss as
a direct result of the reorganization. A shareholder's tax basis in Acquired
Fund shares will carry over to the shareholder's Acquiring Fund Investor2 Class
shares. As a condition to the closing of the reorganization, the Acquired Fund
and the Acquiring Fund will receive an opinion of counsel to the effect that,
for federal income tax purposes, the reorganization will qualify as a tax-free
reorganization and, thus, no gain or loss will be recognized by the Acquired
Fund, the Acquired Fund's shareholders, or the Acquiring Fund as a result of the
reorganization. The Acquired Fund will distribute any undistributed net
investment income and net realized capital gains prior to the reorganization,
and such distribution would be taxable to shareholders.

WHO WILL PAY THE EXPENSES OF THE PROPOSED REORGANIZATION?

Security Investors, or its affiliates, and not the Acquired Fund or the
Acquiring Fund, will pay the expenses directly related to the proposed
reorganization.

HOW DOES THE BOARD RECOMMEND I VOTE?

After considering, among other factors, the terms and conditions of the
reorganization, the investment management policies of, as well as shareholder
services offered by, the Acquired Fund and the Acquiring Fund, the historical
expense ratios of the Acquired Fund and the Acquiring Fund, and the relative
performance of the Acquired Fund and the Acquiring Fund, the Board of Directors
of the Acquired Fund and the Board of Trustees of the Acquiring Fund believe
that reorganizing the Acquired Fund into the Acquiring Fund is in the best
interests of the Funds and their shareholders. In reaching this conclusion, the
boards determined that reorganizing the Acquired Fund into the Acquiring Fund,
which, compared to the Acquired Fund, has a similar investment objective,
comparable investment policies and the same management fee ratio, offers
potential benefits to the Acquired Fund's shareholders. Therefore, the Board of
Directors of the Acquired Fund recommends that you vote FOR the reorganization.

INTRODUCTION

At a meeting held on February 26, 2009, the Board of Directors of Security Cash
Fund (the "Acquired Fund") approved an Agreement and Plan of Reorganization (the
"Reorganization Plan") relating to the proposed reorganization of the Acquired
Fund into U.S. Government Money Market Fund (the "Acquiring Fund" and together
with the Acquired Fund, the "Funds"), a series of Rydex Series Funds. This Proxy
Statement/Prospectus provides you with information about this proposed
reorganization.

If shareholders of the Acquired Fund approve the proposed reorganization, the
Acquired Fund will transfer all of its assets and liabilities to the Acquiring
Fund in exchange solely for shares of Investor2 Class of the Acquiring Fund (the
"Reorganization"). The Acquiring Fund currently does not offer Investor2 Class
shares; however, the Acquiring Fund will start issuing and offering Investor2
Class shares in connection with the Reorganization. Following the transfer of
its assets and liabilities to the Acquiring Fund in exchange for shares of the
Acquiring Fund, the Acquired Fund will distribute to you your pro rata portion
of the shares of the Acquiring Fund that it receives in the Reorganization. You
will receive Investor2 Class shares of the Acquiring Fund having an aggregate
value equal to the aggregate value of shares of the Acquired Fund held by you
immediately prior to the Reorganization. Following the Reorganization, the
Acquired Fund will liquidate.

This Proxy Statement/Prospectus solicits your vote in connection with a special
meeting ("Special Meeting") of shareholders of the Acquired Fund, to be held on
June 19, 2009, at which shareholders of the Acquired Fund will vote on the
Reorganization Plan upon which the Reorganization will be based. Because you, as
a shareholder of the Acquired Fund, are being asked to approve a transaction
that will result in your holding shares of the Acquiring Fund, this document
also serves as a prospectus for the Acquiring Fund, whose investment objective
is to seek to provide security of principal, high current income, and liquidity.

Both the Acquired Fund and the Acquiring Fund are open-end management investment
companies operated as money market funds. AN INVESTMENT IN THE FUNDS IS NOT
INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER
GOVERNMENT AGENCY. ALTHOUGH EACH FUND SEEKS TO PRESERVE THE VALUE OF YOUR
INVESTMENT AT $1.00 PER SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE
FUNDS.

This Proxy Statement/Prospectus, which you should retain for future reference,
contains important information about the Acquiring Fund that you should know
before voting on the proposal or investing in the Acquiring Fund. A Statement of
Additional Information ("SAI") dated May 8, 2009 relating to this Proxy
Statement/Prospectus, and containing additional information about the
Reorganization and the parties thereto, has been filed with the U.S. Securities
and Exchange Commission ("SEC") and is incorporated herein by reference. A more
detailed discussion of the investment objectives, policies, restrictions, risks
and performance of the Acquired Fund can be found in the following documents,
which have been filed with the SEC:

o    The Acquired Fund's Prospectus and Statement of Additional Information,
     dated May 1, 2009 (File No. 002-68387); and

o    The Acquired Fund's annual report for the fiscal year ended December 31,
     2008 (File No. 811-03073).

The Acquiring Fund currently issues four classes of shares: A Class, C Class,
Investor Class and Advisor Class and will start issuing and offering Investor2
Class shares in connection with the Reorganization. For a more detailed
discussion of the investment objectives, policies, restrictions, risks and
performance of the Acquiring Fund, please see the following documents, which
have been filed with the SEC:

o    The Acquiring Fund's Investor2 Class share Statement of Additional
     Information, filed March 6, 2009 (File No. 033-59692);" and

                                       6


o     The Acquiring Fund's annual report for the fiscal year ended March 31,
      2008 and semi-annual report for the period ended September 30, 2008 (File
      No. 811-07584).

Each Fund's Prospectus(es), Statement of Additional Information, annual and
semi-annual reports, and a copy of the Statement of Additional Information

SUMMARY

You should read this entire Proxy Statement/Prospectus and accompanying
materials carefully. For additional information, you should consult the Funds'
Prospectuses and the Reorganization Plan, which is attached hereto as Appendix
A.

THE PROPOSED REORGANIZATION -- On February 26, 2009, the Board of Directors of
the Acquired Fund and the Board of Trustees of the Acquiring Fund (the "Boards"
or the "Directors" or "Trustees," as applicable) approved the Reorganization
Plan. Subject to the approval of shareholders of the Acquired Fund, the
Reorganization Plan provides for:

o    the transfer of all of the assets of the Acquired Fund to the Acquiring
     Fund, in exchange for shares of the Investor2 Class of the Acquiring Fund;

o    the assumption by the Acquiring Fund of all of the stated liabilities of
     the Acquired Fund;

o    the distribution of Investor2 Class shares of the Acquiring Fund to the
     shareholders of the Acquired Fund; and

o    the complete liquidation of the Acquired Fund.

The Reorganization is expected to be effective immediately after the close of
business on July 10, 2009, or on a later date as the parties may agree (the
"Closing"). As a result of the Reorganization, each shareholder of the Acquired
Fund will become an Investor2 Class shareholder of the Acquiring Fund. Each
shareholder of the Acquired Fund will hold, immediately after the Closing,
shares of Investor2 Class of the Acquiring Fund having an aggregate value equal
to the aggregate value of the shares of the Acquired Fund held by that
shareholder as of the close of business on the date of the Closing. For purposes
of the Reorganization, the Acquired Fund's assets will be valued based on the
amortized cost valuation procedures of the Acquiring Fund and the shares of the
Acquiring Fund to be issued and exchanged also will be based on the Acquiring
Fund's amortized cost valuation procedures. As a result, shareholders of the
Acquired Fund will exchange shares with an amortized cost price of $1.00 for
Investor2 Class shares of the Acquiring Fund with an amortized cost price of
$1.00.

Security Investors, LLC ("Security Investors"), the Acquired Fund's investment
adviser, or its affiliates, will bear all expenses relating to the
Reorganization.

Approval of the Reorganization Plan requires the affirmative vote of a majority
of the outstanding shares of the Acquired Fund. In the event that the
shareholders of the Acquired Fund do not approve the Reorganization, the
Acquired Fund will continue to operate as a separate entity, and the Board will
determine what further action, if any, to take, which could include liquidation
of the Acquired Fund.

AFTER CAREFUL CONSIDERATION, THE BOARD UNANIMOUSLY APPROVED THE PROPOSED
REORGANIZATION. THE BOARD RECOMMENDS THAT YOU VOTE "FOR" THE PROPOSED
REORGANIZATION.

In considering whether to approve the Reorganization, you should note that:

o    Both the Acquired Fund and the Acquiring Fund are money market funds.
     Pursuant to the rules for money market funds, each Fund is managed to
     maintain a stable price per share of $1.00, although there is no guarantee
     that the price will be constantly maintained and it is possible to lose
     money by investing in the Fund.

                                       7


o    The Acquired Fund and the Acquiring Fund have a similar investment
     objective. The Acquired Fund seeks as high a level of current income as is
     consistent with preservation of capital and liquidity, and the Acquiring
     Fund seeks to provide security of principal, high current income, and
     liquidity.

o    Both Funds invest in money market instruments. However, the Acquiring Fund
     invests primarily in money market instruments issued or guaranteed as to
     principal and interest by the U.S. Government, its agencies or
     instrumentalities, and enters into repurchase agreements fully
     collateralized by U.S. Government securities, while the Acquired Fund
     invests in high-quality money market instruments of non-government issuers
     rated in the highest credit rating categories.

o    Shareholders of the Acquired Fund will hold, immediately after the Closing
     of the Reorganization, shares of Investor2 Class of the Acquiring Fund,
     which have substantially the same purchase, redemption and exchange
     policies as shares of the Acquired Fund. Investor2 Class shares of the
     Acquiring Fund will permit shareholders of the Acquired Fund to continue to
     exchange their shares for shares of other Security Funds and it is expected
     that some time after the Reorganization, they will also be able to exchange
     their shares for shares of the Rydex Funds.

o    Security Investors serves as investment adviser for the Acquired Fund, and
     Rydex Investments serves as investment adviser for the Acquiring Fund. Both
     advisers are under common control and are owned by Security Benefit.

o    Both Funds have the same management fee at the annual rate of 0.50% of the
     value of the respective Fund's average daily net assets. The Acquiring
     Fund's historical gross and net operating expense ratios were lower than
     those of the Acquired Fund. However, there is no guarantee that this trend
     will continue in the future.

o    The Funds have similar dividend and distribution policies; however, there
     are some minor differences with respect to when an investment made in, or
     redeemed from, the Funds would be entitled to receive dividends. (See the
     section titled "Information About the Reorganization - Dividends and Other
     Distributions" below for more information.)

o    The Funds expect that the Reorganization will be considered a tax-free
     reorganization within the meaning of section 368(a)(1) of the Internal
     Revenue Code of 1986 (the "Code"). As such, shareholders of the Funds will
     not recognize gain or loss as a result of the Reorganization.

o    The Reorganization is not expected to require a transition of the Funds'
     portfolios (i.e., the Acquired Fund portfolio will not be re-aligned to
     resemble the portfolio of the Acquiring Fund prior to the Reorganization
     and the Acquiring Fund is not expected to liquidate a substantial portion
     of the portfolio of the Acquired Fund immediately after the
     Reorganization), which will limit costs.

PRINCIPAL RISKS OF INVESTING IN THE FUNDS - Because both Funds are money market
funds with similar investment objectives and some comparable investment
strategies, certain principal risks associated with an investment in the Funds
are similar, although they may be described differently in the Funds'
Prospectuses. As a money market fund, each Fund's yield will fluctuate as the
short-term securities in its portfolio mature and the proceeds are reinvested in
securities with different interest rates. Although each Fund is managed to
maintain a stable price per share of $1.00, there is no guarantee that the price
will be constantly maintained. Also, as with any other mutual fund, there can be
no assurance that the Acquired Fund or the Acquiring Fund will achieve its
investment objective.

As discussed above, the Acquiring Fund invests primarily in money market
instruments issued or guaranteed as to principal and interest by the U.S.
government, its agencies or instrumentalities, and enters into repurchase
agreements fully collateralized by U.S. government securities while the Acquired
Fund invests in different types of money market instruments such as commercial
paper, notes and obligations of non-governmental issuers within the two highest
credit ratings. As a result, the Acquired Fund may be exposed to somewhat higher
investment risks than the Acquiring Fund. The following summarizes principal
risks of investing in the Funds. The fact that a particular risk is not
identified means only that it is not a principal risk

                                       9

of investing in the particular Fund, but it does not mean that the Fund is
prohibited from investing its assets in securities or other assets that give
rise to that risk or that is not subject (to a lesser extent) to that risk.

STABLE PRICE PER SHARE RISK -- Both Funds are subject to stable price per share
risk. Although each Fund seeks to preserve the value of a shareholder's
investment at $1.00 per share, it is possible to lose money by investing in
either Fund. An investment in the Acquiring Fund, as in the Acquired Fund, is
not is not a bank deposit and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency.

INTEREST RATE RISK -- Both Funds are subject to interest rate risk. Investments
in fixed-income securities are subject to the possibility that interest rates
could rise, causing the value of a Fund's securities, and share price, to
decline. Interest rate risk also involves the potential for decline in a Fund's
yield (the rate of dividends the Fund pays) in the event of declining interest
rates.

CREDIT RISK -- Both Funds are subject to credit risk. It is possible that some
issuers of fixed-income securities will not make payments on debt securities
held by a Fund, or there could be defaults on repurchase agreements held by the
Fund. Also, an issuer may suffer adverse changes in financial condition that
could lower the credit quality of a security, leading to greater volatility in
the price of the security and in shares of a Fund. A change in the credit
quality rating of a security can affect its liquidity and make it more difficult
for a Fund to sell. Because the Acquiring Fund invests primarily in U.S.
government securities, credit risk is generally higher for the Acquired Fund.

PREPAYMENT RISK -- Both Funds are subject to prepayment risk, although this risk
is generally higher for the Acquired Fund. The issuers of securities held by a
Fund may be able to prepay principal due on the securities, particularly during
periods of declining interest rates. Securities subject to prepayment risk
generally offer less potential for gains when interest rates decline, and may
offer a greater potential for loss when interest rates rise. In addition, rising
interest rates may cause prepayments to occur at a slower than expected rate,
thereby effectively lengthening the maturity of the security and making the
security more sensitive to interest rate changes. Prepayment risk is a major
risk of mortgage-backed securities and certain asset-backed securities.

MARKET RISK -- Both Funds are subject to market risk. Most securities fluctuate
in price, sometimes dramatically. These movements may result from factors
affecting individual issuers, or from broader influences like changes in
interest rates, market conditions, investor confidence or changes in economic,
political or financial market conditions.

     the current fiscal year. The pro forma fees and expenses show estimated
     fees and expenses of the Acquiring Fund's Investor2 Class for the current
     fiscal year after giving effect to the proposed Reorganization.

(2)  The Acquired Fund has only classified its shares into one class, Class A.

(3)  The Acquiring Fund currently issues four classes of shares: A Class, C
     Class, Investor Class and Advisor Class, which are not offered in this
     Proxy Statement/Prospectus. The Acquiring Fund will start issuing and
     offering Investor2 Class shares in connection with the Reorganization.

(4)  The Acquired Fund's total annual operating expenses for the most recent
     fiscal year ended December 31, 2008 were reduced due to a contractual cap
     of fees by Security Investors, the Acquired Fund's investment adviser.
     Under the investment management agreement between the Acquired Fund and
     Security Investors, Security Investors guarantees that the aggregate annual
     expenses of the Acquired Fund, exclusive of interest and taxes,
     extraordinary expenses (such as litigation), but inclusive of Security
     Investors' compensation, shall not exceed an amount equal to 1% of the
     average daily net assets of the Acquired Fund for the year. Brokerage fees
     and commissions incurred in connection with the purchase or sale of any
     securities by the Acquired Fund are not deemed to be expenses. This
     agreement is renewable annually and may be terminated upon sixty days
     notice to Security Investors.

(5)  Security Investors may also voluntarily waive its fees or reimburse Fund
     operating expenses in an attempt to maintain a positive yield for the
     Acquired Fund. This voluntary waiver is in addition to any contractual
     waivers already in place and it may be discontinued at any time. There is
     no guarantee that the Acquired Fund will be able to able to maintain a
     positive yield.

EXAMPLES- The examples below are intended to help you compare the cost of
investing in the Acquired Fund's shares and the Acquiring Fund's Investor2 Class
shares, and in the Acquiring Fund's Investor2 Class shares after the
Reorganization on a pro forma basis. Your actual costs may be higher or lower.
The example assumes that you invest $10,000 in each Fund and in the Acquiring
Fund after the Reorganization for the time periods indicated and assumes total
annual fund operating expenses before any fee reduction. The example also
assumes that your investment has a 5% return each year and that each Fund's
operating expenses remain the same. The 5% return is an assumption and is not

COMPARISON OF FUND PERFORMANCE

The charts and tables below provide some indication of the risks of investing in
the Acquired and the Acquiring Funds by showing changes in the Acquired Fund's
share performance and the Funds' performance from year to year. Fee waivers
and/or expense reimbursements may have reduced the expenses of the Acquired
Fund. In the absence of such waiver or reimbursements, the performance quoted
would be reduced. As with all mutual funds, past performance is not a prediction
of future results.

THE ACQUIRING FUND - INVESTOR CLASS

The past performance shown below is for Investor Class shares of the Acquiring
Fund (which are offered in a different prospectus), not Investor2 Class shares
which have no operating history. Investor2 Class shares would have similar
annual returns as Investor Class shares because both share classes are invested
in the same portfolio of securities. The return for Investor Class shares will
vary from Investor2 Class shares to the extent that the classes do not have the
same expenses. The Investor Class and Investor2 Class shares have substantially
similar expense structures.

PORTFOLIO MANAGERS OF THE FUNDS - The Funds are managed by different portfolio
managers. The Acquired Fund is managed by a single portfolio manager, Christina
Fletcher, of Security Investors. The Acquiring Fund is co-managed by three
portfolio managers of Rydex Investments: Michael P. Byrum, Michael J. Dellapa
and Ryan A. Harder. For additional information about the portfolio managers of
the Acquiring Fund, please refer to the section titled "Portfolio Managers" in
Appendix B.

FORM OF ORGANIZATION AND BOARD MEMBERS - The Acquired Fund is a Kansas
corporation registered as an open-end management investment company and governed
by a Board of Directors which currently consists of six directors. The Acquiring
Fund is a series of Rydex Series Funds, a Delaware statutory trust registered as
an open-end management investment company. Rydex Series Funds is governed by a
Board of Trustees which currently consists of eight trustees. The Acquired Fund
and Rydex Series Funds have different board members. For a description of the
board members of Rydex Series Fund, see Appendix C.

INVESTMENT RESTRICTIONS OF THE FUNDS - The Funds' investment restrictions are
generally similar and consistent, although there are some differences. For a
comparison of the Funds' fundamental and non-fundamental investment
restrictions, see Appendix D.

[TEMPORARY GUARANTEE PROGRAM FOR MONEY MARKET FUNDS - Each Fund currently
participates in the U.S. Department of the Treasury's Temporary Guarantee
Program for Money Market Funds (the "Program"), which is scheduled to expire on
[April 30, 2009]. The Program may be extended at the sole discretion of the U.S.
Treasury Department ("Treasury"), but, in any event, will terminate no later
than September 18, 2009. If the Program is extended by Treasury, in order to
continue participating in each extension of the Program (the "Program
Extension"), each Fund would have to renew its participation under the terms
proposed by the Treasury, including paying an additional participation fee.
Under the Program, Treasury will guarantee the share price of shares of a Fund
outstanding as of September 19, 2008 at $1.00 per share if the Fund's net asset
value falls below $0.995 (a "Guarantee Event"). The Program provides a guarantee
to shareholders as of the close of business on September 19, 2008 ("Eligible
Shareholders") up to the lesser of (i) the number of shares owned by an Eligible
Shareholder on September 19, 2008 and (ii) the number of shares owned by an
Eligible Shareholder upon the occurrence of the Guarantee Event. In case the
Program is extended for a period beyond the Closing Date of the Reorganization,
any guarantee in effect at that time for the Acquired Fund's Eligible
Shareholders would likely be assumed by the Acquiring Fund, subject to certain
conditions. The Program does not protect investors who were not shareholders of
the Funds as of September 19, 2008.

Shareholders of the Acquired Fund should note that the costs for participating
in the Program for the Acquired Fund have been borne by Security Investors or
its affiliates and not the Acquired Fund and its shareholders. The Acquiring
Fund's costs for participating in the Program, however, have been borne by the
Acquiring Fund (and,

                                       14

ultimately, its shareholders). If the Reorganization is consummated, Eligible
Shareholders of the Acquired Fund could thus have to bear some costs to
participate in Program Extension(s) (such costs are unknown as of the time this
document is prepared).]

FINANCIAL HIGHLIGHTS FOR THE ACQUIRED FUND - The financial highlights providing
information about the financial performance of the Acquired Fund is set forth in
Appendix E.

INFORMATION ABOUT THE REORGANIZATION

THE REORGANIZATION PLAN -- The Reorganization Plan provides for the transfer of
all of the assets and stated liabilities of the Acquired Fund to the Acquiring
Fund solely in exchange for shares of Investor2 Class of the Acquiring Fund
having an amortized cost price equal to the amortized cost price of the Acquired
Fund's shares, the Acquired Fund's only class of shares. The Acquired Fund will
distribute the shares of the Acquiring Fund received in the exchange to its
shareholders, and then the Acquired Fund will be liquidated. After the
Reorganization, each shareholder of the Acquired Fund will own shares of
Investor2 Class of the Acquiring Fund having an aggregate value equal to the
aggregate value of shares of the Acquired Fund held by that shareholder prior to
the Closing. As a result, it is expected that shareholders of the Acquired Fund
will exchange shares with an amortized cost price of $1.00 for Investor2 Class
shares of the Acquiring Fund with an amortized cost price of $1.00.

Until the Closing, shareholders of the Acquired Fund will continue to be able to
redeem their shares. Redemption requests received after the Closing will be
treated as requests received for the redemption of Acquiring Fund shares
received by the shareholder in the Reorganization.

The obligations of the Funds under the Reorganization Plan are subject to
various conditions, including approval of the shareholders of the Acquired Fund.
The Reorganization Plan also requires that the Funds take, or cause to be taken,
all actions, and do or cause to be done, all things reasonably necessary, proper
or advisable to consummate and make effective the transactions contemplated by
the Reorganization Plan. The Reorganization Plan may be terminated by mutual
agreement of the parties or on certain other grounds.

The foregoing summarizes the material aspects of the Reorganization Plan. For a
complete description of the terms and conditions of the Reorganization, see the
Reorganization Plan at Appendix A, which qualifies in its entirety the summary
of the Reorganization Plan.

REASONS FOR THE REORGANIZATION AND BOARD CONSIDERATIONS -- The proposed
Reorganization was presented to the Board of Directors of the Acquired Fund and
the Board of Trustees of Rydex Series Funds for consideration and approval at
meetings held on February 26, 2009. The Acquired Fund and the Acquiring Fund are
part of two different fund complexes managed by Security Investors and Rydex
Investments, which are affiliated with each other. As management is integrating
the asset management businesses of Security Investors and Rydex Investments, it
is also in the process of consolidating the Funds' distribution and transfer
agency platforms into a single platform. Accordingly, management proposed to
consolidate two money market fund options by reorganizing the Acquired Fund into
the Acquiring Fund. Furthermore, as the current economic environment lowers the
Funds' yields and performance and thus leads to the increase of management's
waivers of the Funds' expenses, such Reorganization would also help management
to reduce costs of managing the Funds.

The Directors/Trustees of the Funds, including all of the Directors/Trustees who
are not "interested persons" (as defined in the Investment Company Act of 1940),
determined that the interests of the shareholders of the respective Funds would
not be diluted as a result of the proposed Reorganization, and that the proposed
Reorganization was in the best interests of each of the Funds and its
shareholders. The Board, in recommending the Reorganization, considered a number
of factors, including the following:

1.   The Reorganization would not dilute the interests of either Fund's current
     shareholders.

2.   The Funds have similar investment objectives and comparable performance
     records, and as a result, the Reorganization would permit Acquired Fund
     shareholders to pursue the same investment goals in a substantially larger
     fund, which is in a better position to achieve economies of scale (although
     there is no guarantee that the economies of scale will, in fact, be
     achieved);

                                       15

3.   The similarities and differences between the Acquired Fund's and the
     Acquiring Fund's investment strategies and restrictions, and whether the
     Reorganization will allow shareholders of the Acquired Fund to continue to
     participate in a professionally managed portfolio within the same group of
     mutual funds.

4.   The relative sizes of the Acquired Fund and the Acquiring Fund, including
     that the Acquiring Fund has a larger asset base and thus is in a better
     position to achieve increased investment opportunities, enhanced portfolio
     diversification and/or liquidity, and economies of scale.

5.   The alternatives to the Reorganization, which include liquidating the
     Acquired Fund.

6.   The expense ratios and information regarding fees and expenses of the
     Acquired Fund and the Acquiring Fund (and fee waivers, expense
     reimbursements maintained by the Funds' investment advisers), which
     indicate that both Funds have the same management fee ratio and the
     historical gross and net operating expense ratios of the Acquiring Fund
     have been lower that those of the Acquired Fund.

7.   Costs of the Reorganization (which are likely to include, accounting,
     custodian, transfer agency, solicitation, mailing and legal fees) will be
     borne by Security Investors or its affiliates, and not the Funds.

8.   As Investor2 Class shareholders of the combined Acquiring Fund will be able
     to continue to exchange their shares for shares of Security Funds, and it
     is expected that they will later be able to also exchange their shares for
     shares of other Rydex Funds, which is thus expected to result in enhanced
     shareholder services for Fund shareholders.

9.   The future potential benefits that may be realized by Security Investors
     and Rydex Investments, which are affiliates, following the Reorganization,
     including the costs to manage the combined Fund.

10.  The tax-free nature of the Reorganization to each Fund and its
     shareholders.

THE BOARD RECOMMENDS THAT SHAREHOLDERS OF THE ACQUIRED FUND VOTE "FOR" THE
REORGANIZATION. If the shareholders of the Acquired Fund do not approve the
Reorganization, the Board will determine what, if any, additional action should
be taken. Such action could even include liquidation of the Acquired Fund.

TAX CONSIDERATIONS -- The Reorganization is intended to qualify for federal
income tax purposes as a tax-free reorganization under Section 368 of the
Internal Revenue Code of 1986, as amended (the "Code"). Accordingly, pursuant to
this treatment, neither the Acquired Fund, the Acquiring Fund, nor the
shareholders will recognize any gain or loss for federal income tax purposes
from the transactions contemplated by the Reorganization Plan. As a condition to
the closing of the Reorganization, the Funds will receive an opinion from the
law firm of Dechert LLP to the effect that the Reorganization will qualify as a
tax-free reorganization for federal income tax purposes. That opinion will be
based in part upon certain assumptions and upon certain representations made by
the Funds.

Immediately prior to the Reorganization, the Acquired Fund will pay a dividend
or dividends which, together with all previous dividends, will have the effect
of distributing to the shareholders all of the Acquired Fund's investment
company taxable income for taxable years ending on or prior to the
Reorganization (computed without regard to any deduction for dividends paid) and
all of its net capital gains, if any, realized in taxable years ending on or
prior to the Reorganization (after reduction for any available capital loss
carryforward). The distributed amounts will include any net gains realized as a
result of portfolio transitioning. Such dividends will be included in the
taxable income of the Acquired Fund's shareholders.

EXPENSES OF THE REORGANIZATION -- Security Investors, LLC ("Security
Investors"), the Acquired Fund's investment adviser, or its affiliates, will
bear all expenses relating to the Reorganization. The costs of the
Reorganization include, but are not limited to, costs associated with
preparation of the Acquiring Fund's registration statement, printing and
distributing the Acquiring Fund's prospectus and the Acquired Fund's proxy
materials, proxy solicitation expenses, legal fees, accounting fees, securities
registration fees, and expenses of holding the Special Meeting. The estimated
cost of the Reorganization is approximately $85,000.

DIVIDENDS AND OTHER DISTRIBUTIONS - Each Fund declares dividends from its income
daily and pays them monthly or upon redemption. Each Fund distributes any net
capital gains, if any, that it has realized at least annually. The Funds'
dividends and distributions will be reinvested in shares of the Funds, unless
shareholders elect to receive payment in cash. With respect to the rights to
receive dividends, shareholders should note differences between the Funds,
including, without limitation:

                                       16


o    An investment made on a business day in the Acquired Fund would receive the
     following business day's dividend, while such an investment in the
     Acquiring Fund would receive the same business day's dividend. For the
     Acquired Fund, an investment is considered to be made on a business day if
     it is received prior to 3:00 p.m. Central time. For the Acquiring Fund, an
     investment is considered to be made on a business day only if it is
     received prior to 1:00 p.m. Eastern time

o    An investment redeemed from the Acquired Fund on a business day would
     receive any undistributed dividends, including any dividend declared on the
     day of the redemption as its final dividend. An investment redeemed from
     the Acquiring Fund after 1:00 p.m. Eastern time on a business day would
     receive that day's dividend as its final dividend, while such an investment
     would not be entitled to receive that day's dividend if withdrawn prior to
     1:00 p.m. Eastern time.

If the Reorganization Plan is approved by shareholders of the Acquired Fund,
then as soon as practicable before the Closing, the Acquired Fund will pay its
shareholders a cash distribution of all undistributed net investment income and
undistributed realized net capital gains.

CAPITALIZATION OF THE FUNDS - The Acquired Fund has only classified its shares
into one class of shares and the Acquiring Fund currently has four classes of
shares: A Class, C Class, Investor Class and Advisor Class, which are not
offered in this Proxy Statement/Prospectus. The Acquiring Fund will start
issuing and offering Investor2 Class shares in connection with the
Reorganization.

The following table shows on an unaudited basis the capitalization of the each
Fund as of December 31, 2008 and on a pro forma basis as of December 31, 2008,
after giving effect to the Reorganization.

As of December 31, 2008, the Acquiring Fund had not offered Investor2 Class
shares. Each share has one vote and shares have no preemptive or subscription
rights and are freely transferable. All share classes of the Acquiring Fund
invest in the same portfolio of securities, but the classes are subject to
different charges and expenses.

GENERAL INFORMATION

OTHER BUSINESS - The Directors do not know of any matters to be presented at the
Special Meeting other than those set forth in this proxy statement. If other
business should properly come before the Special Meeting, proxies will be voted
in accordance with the judgment of the persons named in the accompanying proxy.

PROXY SOLICITATION - The Board is soliciting Acquired Fund shareholders'
proxies. The principal solicitation of proxies will be by the mailing of this
Proxy Statement/Prospectus commencing on or about May 16, 2009, but proxies may
also be solicited by telephone and/or in person by representatives of Security
Investors or its affiliate(s), or The Altman Group, a private proxy services
firm. If we have not received your vote as the date of the Special

                                       17

Meeting approaches, you may receive a call from these parties to ask for your

of retaining The Altman Group, preparation and mailing of the Notice, Proxy
Statement/Prospectus and proxy, and the solicitation of proxies, including
reimbursements to broker-dealers and others who forwarded proxy materials to
their clients, will be borne by Security Investors. The estimated cost of
retaining The Altman Group is approximately $20,000.

SHAREHOLDER VOTING - Shareholders of record at the close of business on April
20, 2009 (the "Record Date") are entitled to notice of, and to vote at, the
Special Meeting. As of the Record Date, there were issued and outstanding [___]
shares of the Acquired Fund.

The persons owning of record or beneficially 5% or more of the outstanding
shares of the each Fund as of the Record Date, are set forth in Appendix F.

Shareholders are entitled to one vote for each share held and fractional votes
for fractional shares. The presence in person or by proxy of the holders of a
majority of the Acquired Fund's shares that are issued and outstanding and
entitled to vote on the Record Date is required to constitute a quorum at the
Special Meeting, and therefore must be present for the transaction of business
at the Special Meeting. Shares held by shareholders present in person or
represented by proxy at the Special Meeting will be counted both for the
purposes of determining the presence of a quorum and for calculating the votes
cast on the issues before the Special Meeting.

Abstentions are counted as shares eligible to vote at the Special Meeting in
determining whether a quorum is present, but do not represent votes cast with
respect to the proposal. "Broker non-votes" are counted as shares eligible to
vote at the Special Meeting in determining whether a quorum is present but do
not represent votes cast with respect to the proposal. "Broker non-votes" are
shares held by a broker or nominee as to which instructions have not been
received from the beneficial owners or persons entitled to vote, and the broker
or nominee does not have discretionary voting power.

In the event that a quorum is not present at the Special Meeting, or a quorum is
present but sufficient votes to approve a proposal are not received, the persons
named as proxies may propose one or more adjournments of the Special Meeting to
permit further solicitation of proxies or to obtain the vote required for
approval of one or more proposals. Any such adjournment will require the
affirmative vote of a majority of those shares represented at the Special
Meeting in person or by proxy. The persons named as proxies will vote those
proxies which they are entitled to vote FOR the proposal in favor of such an
adjournment and will vote those proxies required to be voted AGAINST the
proposal against any such adjournment. A shareholder vote may be taken prior to
any adjournment of the Special Meeting on any proposal for which there are
sufficient votes for approval, even though the Special Meeting is adjourned as
to other proposals.

In order that your shares may be represented at the Special Meeting, you are
requested to vote your shares by mail, the Internet, or by telephone by
following the enclosed instructions. If you wish to participate in the Special
Meeting, please submit the proxy card originally sent with the Proxy
Statement/Prospectus or attend the Special Meeting in person. Any proxy given by
a shareholder, whether in writing, by telephone or via the Internet is
revocable. A shareholder may revoke the proxy at any time prior to its use by
filing with the Acquired Fund a written revocation or a duly executed proxy card
bearing a later date. In addition, any shareholder who attends the Special
Meeting in person may vote by ballot at the Special Meeting, thereby canceling
any proxy previously given. However, attendance in-person at the Special
Meeting, by itself, will not revoke a previously tendered proxy. If you vote by
telephone or the Internet, please do not return your proxy card, unless you
later elect to change your vote.

VOTE REQUIRED - Approval of the Reorganization Plan requires the affirmative
vote of a majority of the outstanding shares of the Acquired Fund. Assuming the
presence of a quorum, abstentions and broker non-votes have the effect of a
negative vote on the proposed Reorganization.

SHAREHOLDER REPORTS - Shareholders can find important information about the
Acquired Fund in the annual report for the fiscal year ended December 31, 2008
and about the Acquiring Fund in the annual report for the fiscal year ended
March 31, 2008 and the semi-annual report for the six month period ended
September 30, 2008.

SHAREHOLDER PROPOSALS - As a general matter, the Acquired Fund does not hold
annual meetings of shareholders. Shareholders wishing to submit proposals for
inclusion in a proxy statement for a subsequent meeting (if any)

                                       18

should send their written proposals to the secretary of Security Cash Fund, One
Security Benefit Place, Topeka, KS 66636-0001.

Proposals must be received a reasonable time prior to the date of a meeting of
shareholders to be considered for inclusion in the proxy materials for a
meeting. Timely submission of a proposal does not, however, necessarily mean
that the proposal will be included. Persons named as proxies for any subsequent
shareholders' meeting will vote in their discretion with respect to proposals
that are not included herein and that may require a vote (such as proposals
submitted on an untimely basis).

TO ENSURE THE PRESENCE OF A QUORUM AT THE SPECIAL MEETING, WE REQUEST PROMPT
EXECUTION AND RETURN OF THE ENCLOSED PROXY. A SELF-ADDRESSED, POSTAGE-PAID
ENVELOPE IS ENCLOSED FOR YOUR CONVENIENCE.

                                       19


                APPENDIX A - AGREEMENT AND PLAN OF REORGANIZATION

     THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Reorganization Plan") is
adopted as of this [ ] day of [ ], 2009, by and between Rydex Series Funds (the
"Trust"), a Delaware statutory trust with its principal place of business at
9601 Blackwell Road, Suite 500, Rockville, Maryland 20850, on behalf of its
series, U.S. Government Money Market Fund (the "Acquiring Fund"), and Security
Cash Fund (the "Acquired Fund") and, collectively with the Trust, the
"Parties"), a Kansas corporation with its principal place of business at One
Security Benefit Place, Topeka, Kansas 66636-0001.

     This Reorganization Plan is intended to be and is adopted as a plan of
reorganization and liquidation within the meaning of Section 368(a)(1) of the
United States Internal Revenue Code of 1986, as amended (the "Code"). The
reorganization to which this Reorganization Plan applies (the "Reorganization")
will consist of the transfer of all of the assets of the Acquired Fund to the
Acquiring Fund in exchange solely for Investor Class shares of the Acquiring
Fund (the "Acquiring Fund Shares"); the assumption by the Acquiring Fund of all
liabilities of the Acquired Fund; and the distribution of the Acquiring Fund
Shares to the shareholders of the Acquired Fund, the sole class of shareholders
of the Acquired Fund, in complete liquidation and termination of the Acquired
Fund as provided herein, all upon the terms and conditions hereinafter set forth
in this Reorganization Plan.

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

     WHEREAS, the Trustees of the Trust have determined that the exchange of all
of the assets of the Acquired Fund for the Acquiring Fund Shares and the
assumption of all liabilities of the Acquired Fund by the Acquiring Fund is in
the best interests of the Acquiring Fund and its shareholders and that the
interests of the existing shareholders of the Acquiring Fund would not be
diluted as a result of this transaction; and

     WHEREAS, the Directors of the Acquired Fund also have determined, with
respect to the Acquired Fund, that the exchange of all of the assets of the
Acquired Fund for the Acquiring Fund Shares and the assumption of all
liabilities of the Acquired Fund by the Acquiring Fund is in the best interests
of the Acquired Fund and its shareholders and that the interests of the existing
shareholders of the Acquired Fund would not be diluted as a result of this
transaction;

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

1.   TRANSFER OF ASSETS OF THE ACQUIRED FUND TO THE ACQUIRING FUND IN EXCHANGE
     FOR THE ACQUIRING FUND SHARES, THE ASSUMPTION OF STATED ACQUIRED FUND
     LIABILITIES AND THE LIQUIDATION OF THE ACQUIRED FUND

     1.1. Subject to the requisite approvals of the shareholders of the Acquired
          Fund and the other terms and conditions herein set forth and on the
          basis of the representations and warranties contained herein, the
          Acquired Fund will transfer all of the Acquired Fund's assets, as set
          forth in paragraph 1.2, to the Acquiring Fund, and the Acquiring Fund
          agrees in exchange therefor: (i) to deliver to the Acquired Fund the
          number of full and fractional Acquiring Fund Shares determined by
          dividing the value of the Acquired Fund's net assets, computed in the
          manner and as of the time and date set forth in paragraph 2.2, by the
          net asset value of one Acquiring Fund Share, computed in the manner
          and as of the time and date set forth in paragraph 2.2; and (ii) to
          assume the stated liabilities of the Acquired Fund, as set forth in
          paragraph 1.3. Such transactions shall take place at the closing
          provided for in paragraph 3.1 (the "Closing"). In lieu of delivering
          certificates for the Acquiring Fund Shares, the Acquiring Fund shall
          credit the Acquiring Fund Shares to the Fund's account on the books of
          the Acquiring Fund and shall deliver a confirmation thereof to the
          Fund.

     1.2. The assets of the Acquired Fund to be acquired by the Acquiring Fund
          shall consist of all assets and property, including, without
          limitation, all cash, securities, claims, commodities and futures
          interests and dividends or interests receivable that are owned by the
          Acquired Fund and any deferred or prepaid expenses shown as an asset
          on the books of the Acquired Fund (the "Acquired Fund Assets") on the
          closing date provided for in paragraph 3.1 (the "Closing Date").

                                      A-1


     1.3. The Acquired Fund will endeavor to identify and, to the extent
          practicable, discharge all of its known liabilities and obligations
          prior to the Closing Date. The Acquiring Fund shall assume the
          liabilities, expenses, costs, charges and reserves reflected on the
          books of the Acquired Fund, as of the Valuation Date, in accordance
          with U.S. generally accepted accounting principles, consistently
          applied ("GAAP") (the "Acquired Fund Liabilities"). The Acquiring Fund
          shall not assume any other liabilities, whether absolute or
          contingent. On or as soon as practicable prior to the Closing Date,
          the Acquired Fund will declare and pay to its shareholders of record
          one or more dividends and/or other distributions that, together with
          all previous distributions, shall have the effect of distributing to
          its shareholders (i) all of its investment company taxable income and
          all of its net realized capital gains, if any, for the period from the
          close of its last taxable year to the end of the business day on the
          Closing; and (ii) any undistributed investment company taxable income
          and net capital gain from any period to the extent not otherwise
          distributed.

     1.4. Delivery of the Acquired Fund Assets shall be made on the Closing Date
          and shall be delivered to the Acquiring Fund's 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, encumbrances, 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.

     1.5. Immediately after the transfer and delivery of assets provided for in
          paragraphs 1.1 and 1.4, the Acquired Fund will distribute to its
          shareholders of record, determined as of immediately after the close
          of business on the Closing Date (the "Acquired Fund Shareholders"), on
          a pro rata basis, the Acquiring Fund Shares received by the Acquired
          Fund pursuant to paragraph 1.1, and will, promptly thereafter,
          terminate in accordance with the applicable laws of the State of
          Kansas and the federal securities laws. Such distribution and
          termination will be accomplished, with respect to the Acquired Fund's
          shares, by the transfer of the Acquiring Fund Shares then credited to
          the account of the Acquired Fund on the books of the Acquiring Fund to
          open accounts on the share records of the Acquiring Fund in the names
          of the Acquired Fund Shareholders. The aggregate value of Acquiring
          Fund Shares to be so credited shall be equal to the aggregate value of
          the Acquired Fund shares owned by such shareholders on the Closing
          Date, each based on amortized cost prices. All issued and outstanding
          shares of the Acquired Fund will simultaneously be canceled on the
          books of the Acquired Fund. The Acquiring Fund will not issue
          certificates representing the Acquiring Fund Shares in connection with
          such exchange.

     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 Acquiring Fund's then-current
          prospectus and statement of additional information.

     1.7. Any reporting responsibility of the Acquired Fund including, but not
          limited to, the responsibility for filing of regulatory reports, tax
          returns, or other documents with the Securities and Exchange
          Commission (the "Commission"), any state securities commission, and
          any federal, state or local tax authorities or any other relevant
          regulatory authority, is and shall remain the responsibility of the
          Acquired Fund up to and including the Closing Date and such later date
          on which the Acquired Fund's existence is terminated pursuant to
          paragraph 1.5.

2.   VALUATION

     2.1. The value of the Acquired Fund Assets and the amount of the Acquired
          Fund Liabilities hereunder shall be computed as of the close of
          business on the New York Stock Exchange ("NYSE") on the Closing Date
          (such time and date being hereinafter called the "Valuation Date"),
          using available market quotations (as provided in Rule 2a-7 under the
          Investment Company Act of 1940) in accordance with the valuation
          procedures currently in use by the Acquiring Fund.

     2.2. The value of the Acquired Fund Assets and the amount of the Acquired
          Fund Liabilities, and the value of the Acquiring Fund Shares shall be
          computed as of the Valuation Date based on the amortized cost
          valuation procedures that have been adopted by the Acquiring Fund. Any
          provision in this Reorganization Plan to the contrary notwithstanding,
          if the difference between (i) the net asset value per share of either

                                       A-2


          Fund computed using available market quotations in accordance with
          paragraph 2.1 and (ii) the amortized cost price per share of that Fund
          equals or exceeds $.0025 on the Valuation Date, then the Closing Date
          shall be postponed until such time as the per share difference is less
          than $.0025.

     2.3. The number of Acquiring Fund Shares to be issued (including fractional
          shares, if any) in exchange for the Acquired Fund Assets and the
          assumption of the Acquired Fund Liabilities shall be determined by
          dividing the value of the Acquired Fund Assets and the amount of the
          Acquired Fund Liabilities computed using the same amortized cost
          valuation procedures referred to in paragraph 2.2 by the amortized
          cost price per share of one Acquiring Fund Share, also determined in
          accordance with paragraph 2.2.

     2.4. All computations of value shall be made by the Acquired Fund's
          designated record keeping agent.

3.   CLOSING AND CLOSING DATE

     3.1. The Closing Date shall be July 10, 2009, or such other date as the
          Parties may mutually agree to in writing. All acts taking place at the
          Closing shall be deemed to take place simultaneously as of immediately
          after the close of business on the Closing Date unless otherwise
          agreed to by the parties. The close of business on the Closing Date
          shall be as of 4:00 p.m., Eastern Time. The Closing shall be held at
          the offices of the Acquired Fund or at such other time and/or place as
          to which the Parties may mutually agree in writing.

     3.2. The Acquired Fund shall direct the Custodian of the Acquired Fund (the
          "Acquired Fund Custodian"), to deliver, at the Closing, a certificate
          of an authorized officer stating that (i) the Acquired Fund's
          portfolio securities, cash, and any other assets ("Assets") shall have
          been delivered in proper form to the Acquiring Fund within two
          business days prior to or on the Closing Date, and (ii) all necessary
          taxes in connection with the delivery of the Assets, including all
          applicable federal and state stock transfer stamps, if any, have been
          paid or provision for payment has been made. The Acquired Fund's
          portfolio securities represented by a certificate or other written
          instrument shall be transferred and delivered by the Acquired Fund as
          of the Closing Date for the account of the Acquiring Fund duly
          endorsed in proper form for transfer in such condition as to
          constitute good delivery thereof. The Acquired Fund shall direct the
          Custodian to deliver portfolio securities and instruments deposited
          with a securities depository, as defined in Rule 17f-4 under the
          Investment Company Act of 1940 (the "1940 Act"), as of the Closing
          Date by book entry in accordance with the customary practices of such
          depositories and the custodian for Acquiring Fund.

     3.3. The Acquired Fund shall direct its transfer agent (the "Transfer
          Agent") to deliver, on behalf of the Acquired Fund, at the Closing a
          certificate of an authorized officer stating that its records contain
          the names and addresses of the Acquired Fund Shareholders and the
          number and percentage ownership of outstanding shares owned by each
          such shareholder immediately prior to the Closing.

     3.4. In the event that on the Valuation Date (a) the NYSE or another
          primary trading market for portfolio securities of the Acquiring Fund
          or the Acquired Fund shall be closed to trading or trading thereupon
          shall be restricted, or (b) trading or the reporting of trading on the
          NYSE or elsewhere shall be disrupted so that, in the judgment of the
          Trustees of the Trust or the Board of Directors of the Acquired Fund,
          accurate appraisal of the value of the net assets of the Acquiring
          Fund or the Acquired 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.

4.   REPRESENTATIONS AND WARRANTIES

     4.1. The Acquired Fund, on behalf of the Acquired Fund, represents and
          warrants to the Acquiring Fund as follows:

          (a)  The Acquired Fund is a corporation duly organized and validly

               Acquired Fund of the transactions contemplated herein, except
               such as have been obtained under the 1933 Act, the Securities
               Exchange Act of 1934 (the "1934 Act"), and the 1940 Act, and such

               previous to the date of this Reorganization Plan conforms or
               conformed at the time of its use in all material respects to the
               applicable requirements of the 1933 Act and the 1940 Act and the
               rules and regulations of the Commission thereunder and does not
               or did not at the time of its use 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;

          (e)  On the Closing Date, the Acquired Fund will have good and
               marketable title to the Acquired Fund's assets to be transferred
               to the Acquiring Fund pursuant to paragraph 1.2 and full right,
               power, and authority to sell, assign, transfer and deliver such
               assets hereunder free of any liens or other encumbrances, and
               upon delivery and payment for such assets, the Acquiring Fund

               restrictions as might arise under the 1933 Act, other than as
               disclosed to the Acquiring Fund;

          (f)  The Acquired Fund is not engaged currently, and the execution,
               delivery and performance of this Reorganization Plan will not
               result, in (i) a material violation of the Acquired Fund's
               Articles of Incorporation or By-Laws or of any agreement,
               indenture, instrument, contract, lease or other undertaking to
               which the Acquired Fund is a party or by which it is bound, or
               (ii) the acceleration of any obligation, or the imposition of any
               penalty, under any agreement, indenture, instrument, contract,
               lease, judgment or decree to which the Acquired Fund is a party
               or by which it is bound;

          (g)  The Acquired Fund has no material contracts or other commitments
               (other than this Reorganization Plan) that will be terminated
               with liability to it prior to the Closing Date;

          (h)  Except as otherwise disclosed in writing to and accepted by the
               Acquiring Fund, no litigation or administrative proceeding or
               investigation of or before any court or governmental body is
               presently pending or, to its knowledge, threatened against the
               Acquired Fund or any of its properties or assets that, if
               adversely determined, would materially and adversely affect its
               financial condition or the conduct of its business. The Acquired
               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;

          (i)  The financial statements and financial highlights of the Acquired
               Fund as of and for the year ended December 31, 2008 have been
               audited by Ernst & Young LLP, an independent registered public
               accounting firm. Such statements are in accordance with GAAP, and
               such statements (copies of which have been furnished to the
               Acquiring Fund) present fairly, in all material respects, the
               financial condition of the Acquired Fund as of such date in
               accordance with GAAP, and there are no known contingent
               liabilities of the Acquired Fund required to be reflected on the
               balance sheet or in the notes thereto;

          (j)  Since December 31, 2008, there has not been any material adverse
               change in the Acquired Fund's financial condition, assets,
               liabilities or business, other than changes occurring in the
               ordinary course of business, or any incurrence by the Acquired
               Fund of indebtedness maturing more than one year from the date
               such indebtedness was incurred, except as otherwise disclosed to
               and accepted by the Acquiring Fund. For the purposes of this
               subparagraph (j), a decline in net asset value per share of the
               Acquired Fund due to declines in market values of securities in
               the Acquired Fund's portfolio, the discharge of Acquired Fund
               liabilities, or the redemption of Acquired Fund shares by
               shareholders of the Acquired Fund shall not constitute a material
               adverse change, unless the conditions set forth in paragraph 2.2
               are not satisfied;
                                      A-4


          (k)  On the Closing Date, all Federal and other tax returns and
               reports of the Acquired Fund required by law to have been filed
               by such date (including any extensions) shall have been filed and
               are or will be correct in all material respects, and all Federal
               and other taxes shown as due or required to be shown as due on
               said returns and reports shall have been paid or provision shall
               have been made for the payment thereof, and to the best of the
               Acquired Fund's knowledge, no such return is currently under
               audit and no assessment has been asserted with respect to such
               returns;

          (l)  For each taxable year of its operation (including the taxable
               year ending on the Closing Date), the Acquired Fund has met the
               requirements of Subchapter M of the Code for qualification as a
               regulated investment company and has elected to be treated as
               such, has been eligible to and has computed its Federal income
               tax under Section 852 of the Code, and will have distributed all
               of its investment company taxable income and net capital gain (as
               defined in the Code) that has accrued through the Closing Date,
               and before the Closing Date will have declared dividends
               sufficient to distribute all of its investment company taxable
               income and net capital gain for the period ending on the Closing
               Date;

          (m)  All issued and outstanding shares of the Acquired Fund are, and
               on the Closing Date will be, duly and validly issued and
               outstanding, fully paid and non-assessable by the Acquired Fund
               and have been offered and sold in every state and the District of
               Columbia in compliance in all material respects with applicable
               registration requirements of the 1933 Act and state securities
               laws. All of the issued and outstanding shares of the Acquired
               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, on
               behalf of the Acquired Fund, as provided in paragraph 3.3. The
               Acquired Fund does not have outstanding any options, warrants or
               other rights to subscribe for or purchase any of the shares of
               the Acquired Fund, nor is there outstanding any security
               convertible into any of the Acquired Fund shares;

          (n)  The adoption and performance of this Reorganization Plan will
               have been duly authorized prior to the Closing Date by all
               necessary action, if any, on the part of the Directors of the
               Acquired Fund, and, subject to the approval of the shareholders
               of the Acquired Fund, this Reorganization Plan will constitute a
               valid and binding obligation of the Acquired Fund, enforceable in
               accordance with its terms, subject, as to enforcement, to
               bankruptcy, insolvency, reorganization, moratorium and other laws
               relating to or affecting creditors' rights and to general equity
               principles;

          (o)  The information to be furnished by the Acquired Fund for use in
               registration statements, proxy materials and other documents
               filed or to be filed with any federal, state or local regulatory
               authority (including the Financial Industry Regulatory Authority,
               or any successor organization thereto), which may be necessary in
               connection with the transactions contemplated hereby, shall be
               accurate and complete in all material respects and shall comply
               in all material respects with Federal securities and other laws
               and regulations thereunder applicable thereto.

     4.2. The Trust, on behalf of the Acquiring Fund, represents and warrants to
          the Acquired Fund as follows:

          (a)  The Acquiring Fund is duly organized as a series of the Trust,
               which is a statutory trust duly organized and validly existing
               under the laws of the State of Delaware, with power under the
               Trust's Declaration of Trust to own all of its properties and
               assets and to carry on its business as it is now being conducted;

          (b)  The Trust is a registered investment company classified as a
               management company of the open-end type, and its registration
               with the Commission as an investment company under the 1940 Act
               and the registration of its shares under the 1933 Act, including
               the shares of the Acquiring Fund, are in full force and effect;

          (c)  No consent, approval, authorization, or order of any court or
               governmental authority is required for the consummation by the
               Acquiring Fund of the transactions contemplated herein, except
               such as have been obtained under the 1933 Act, the 1934 Act and
               the 1940 Act and such as may be required by state securities
               laws;

          (d)  The current prospectus and statement of additional information of
               the Acquiring Fund and each prospectus and statement of
               additional information of the Acquiring Fund used during the
               three years previous to the date of this Reorganization Plan
               conforms or conformed at the time of its use in all

                                      A-5


               material respects to the applicable requirements of the 1933 Act
               and the 1940 Act and the rules and regulations of the Commission
               thereunder and does not or did not at the time of its use 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;

          (e)  On the Closing Date, the Acquiring Fund will have good and
               marketable title to the Acquiring Fund's assets, free of any
               liens of other encumbrances, except those liens or encumbrances
               as to which the Acquired Fund has received notice and necessary
               documentation at or prior to the Closing;

          (f)  The Acquiring Fund is not engaged currently, and the execution,
               delivery and performance of this Reorganization Plan will not
               result, in (i) a material violation of the Trust's Declaration of
               Trust or By-Laws 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, or (ii) the acceleration of
               any obligation, or the imposition of any penalty, under any
               agreement, indenture, instrument, contract, lease, judgment or
               decree to which the Acquiring Fund is a party or by which it is
               bound;

          (g)  Except as otherwise disclosed in writing to and accepted by the
               Acquired Fund, no litigation or administrative proceeding or
               investigation of or before any court or governmental body is
               presently pending or, to its knowledge, threatened against the
               Acquiring Fund or any of its properties or assets that, 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 herein
               contemplated;

          (h)  The financial statements of the Acquiring Fund as of and for the
               fiscal year ended March 31, 2008 have been audited by Ernst &
               Young LLP, an independent registered public accounting firm. Such
               statements are in accordance with GAAP consistently applied, and
               such statements (copies of which have been furnished to the
               Acquired Fund) present fairly, in all material respects, the
               financial condition of the Acquiring Fund as of such date in
               accordance with GAAP, and there are no known contingent
               liabilities of the Acquiring Fund required to be reflected on the
               balance sheet or in the notes thereto;

          (i)  Since December 31, 2008, there has not been any material adverse
               change in the Acquiring Fund's 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 otherwise disclosed to
               and accepted by the Acquired Fund. For purposes of this
               subparagraph (i), a decline in net asset value per share of the
               Acquiring Fund due to declines in market values of securities in
               the Acquiring Fund's portfolio, the discharge of Acquiring Fund
               liabilities, or the redemption of Acquiring Fund Shares by
               shareholders of the Acquiring Fund, shall not constitute a
               material adverse change, unless the conditions set forth in
               paragraph 2.2 are not satisfied;

          (j)  On the Closing Date, all Federal and other tax returns and
               reports of the Acquiring Fund required by law to have been filed
               by such date (including any extensions) shall have been filed and
               are or will be correct in all material respects, and all Federal
               and other taxes shown as due or required to be shown as due on
               said returns and reports shall have been paid or provision shall
               have been made for the payment thereof, and to the best of the
               Acquiring Fund's knowledge no such return is currently under
               audit and no assessment has been asserted with respect to such
               returns;

          (k)  For each taxable year of its operation, the Acquiring Fund has
               met the requirements of Subchapter M of the Code for
               qualification as a regulated investment company and has elected
               to be treated as such, has been eligible to and has computed its
               Federal income tax under Section 852 of the Code, has distributed
               all of its investment company taxable income and net capital gain
               (as defined in the Code) for periods ending prior to the Closing
               Date, and will do so for the taxable year including the Closing
               Date;

                                      A-6


          (l)  All issued and outstanding Acquiring Fund Shares are, and on the
               Closing Date will be, duly and validly issued and outstanding,
               fully paid and non-assessable by the Trust and have been offered
               and sold in every state and the District of Columbia in
               compliance in all material respects with applicable registration
               requirements of the 1933 Act and state securities laws. The
               Acquiring Fund does not have outstanding any options, warrants or
               other rights to subscribe for or purchase any Acquiring Fund
               Shares, nor is there outstanding any security convertible into
               any Acquiring Fund Shares;

          (m)  The adoption and performance of this Reorganization Plan will
               have been fully authorized prior to the Closing Date by all
               necessary action, if any, on the part of the Board of Trustees of
               the Trust on behalf of the Acquiring Fund and this Reorganization
               Plan will constitute a valid and binding obligation of the
               Acquiring Fund, enforceable in accordance with its terms,
               subject, as to enforcement, to bankruptcy, insolvency,
               reorganization, moratorium and other laws relating to or
               affecting creditors' rights and to general equity principles;

          (n)  The Acquiring Fund Shares to be issued and delivered to the
               Acquired Fund, for the account of the Acquired Fund Shareholders,
               pursuant to the terms of this Reorganization Plan, will on the
               Closing Date have been duly authorized and, when so issued and
               delivered, will be duly and validly issued Acquiring Fund Shares,
               and will be fully paid and non-assessable by the Trust;

          (o)  The information to be furnished by the Acquiring Fund for use in
               the registration statements, proxy materials and other documents
               that may be necessary in connection with the transactions
               contemplated hereby shall be accurate and complete in all
               material respects and shall comply in all material respects with
               Federal securities and other laws and regulations applicable
               thereto; and

          (p)  That insofar as it relates to Trust or the Acquiring Fund, the
               Registration Statement relating to the Acquiring Fund Shares
               issuable hereunder, and the proxy materials of the Acquired Fund
               to be included in the Registration Statement, and any amendment
               or supplement to the foregoing, will, from the effective date of
               the Registration Statement through the date of the meeting of
               shareholders of the Acquired Fund contemplated therein (i) 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
               provided, however, that the representations and warranties in
               this subparagraph (p) shall not apply to statements in or
               omissions from the Registration Statement made in reliance upon
               and in conformity with information that was furnished by the
               Acquired Fund for use therein, and (ii) comply in all material
               respects with the provisions of the 1933 Act, the 1934 Act and
               the 1940 Act and the rules and regulations thereunder.

     Plan:

     8.1. The Reorganization Plan and the transactions contemplated herein shall
          have been approved by the requisite vote, if any, of the holders of
          the outstanding shares of the Acquired Fund in accordance with the
          provisions of the Acquired Fund's Articles of Incorporation, By-Laws,
          applicable Kansas law and the 1940 Act, and certified copies of the
          resolutions evidencing such approval shall have been delivered to the
          Acquiring Fund. Notwithstanding anything herein to the contrary,
          neither the Acquiring Fund nor the Acquired Fund may waive the
          conditions set forth in this paragraph 8.1;

     8.2. On the Closing Date, no action, suit or other proceeding shall be
          pending or, to its knowledge, threatened before any court or
          governmental agency in which it is sought to restrain or prohibit, or
          obtain damages or other relief in connection with, this Reorganization
          Plan or the transactions contemplated herein;

     8.3. All consents of other parties and all other consents, orders and

          necessary by the Acquiring Fund or the Acquired 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 the Acquired Fund, provided that either party hereto may for
          itself waive any of such conditions;

     8.4. The Registration Statement shall have become effective under the 1933
          Act and no stop orders suspending the effectiveness thereof shall have

          instituted or be pending, threatened or contemplated under the 1933
          Act; and

     8.5. Dechert LLP shall deliver an opinion addressed to the Trust and the
          Acquired Fund substantially to the effect that, based upon certain
          facts, assumptions, and representations, the transaction contemplated
          by this Reorganization Plan shall constitute a tax-free reorganization
          for Federal income tax purposes, unless, based on the circumstances
          existing at the time of the Closing, Dechert LLP determines that the
          transaction contemplated by this Reorganization Plan does not qualify
          as such. The delivery of such opinion is conditioned upon receipt by
          Dechert LLP of representations it shall request of the Acquired Fund
          and the Trust. Notwithstanding anything herein to the contrary, the
          Parties may not waive the condition set forth in this paragraph 8.5.

     connection herewith shall survive the consummation of the transactions

     shall survive the Closing.

                                      A-9


11.  TERMINATION

     This Reorganization Plan and the transactions contemplated hereby may be
     terminated and abandoned either by resolution of the Board of Directors or
     the Board of Trustees, at any time prior to the Closing Date, if
     circumstances should develop that, in the opinion of the Board of Directors
     or the Board of Trustees, make proceeding with the Reorganization Plan
     inadvisable.

12.  AMENDMENTS; WAIVER

     This Reorganization Plan may be amended, modified or supplemented in such
     manner as may be mutually agreed to in writing by the Parties; provided,
     however, that following any meeting of the shareholders called by the
     Acquired Fund pursuant to paragraph 5.2 of this Reorganization Plan, no
     such amendment may have the effect of changing the provisions for
     determining the number of the Acquiring Fund Shares to be issued to the
     Acquired Fund Shareholders under this Reorganization Plan to the detriment
     of such shareholders without their further approval.

     At any time prior to the Closing Date, except as otherwise expressly
     provided, any of the foregoing conditions may be waived by the Board of
     Trustees of the Trust or the Board of Directors of the Acquired Fund if, in
     the judgment of either and upon the advice of counsel, such waiver will not
     have a material adverse effect on the benefits intended under this
     Agreement to the shareholders of the Acquiring Fund or the Acquired Fund,
     as the case may be.

13.  HEADINGS; GOVERNING LAW; ASSIGNMENT; LIMITATION OF LIABILITY

     13.1. The Article and paragraph headings contained in this Reorganization
           Plan are for reference purposes only and shall not affect in any way
           the meaning or interpretation of this Reorganization Plan.

           accordance with the laws of the State of Kansas without regard to its
           principles of conflicts of laws.

           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 Reorganization Plan.

     13.4. It is expressly agreed that the obligations of the parties hereunder
           shall not be binding upon any of the Directors, shareholders,
           nominees, officers, agents, or employees of the Acquired Fund
           personally, but shall bind only property of such party. The execution
           and delivery by such officers shall not be deemed to have been made
           by any of them individually or to impose any liability on any of them
           personally, but shall bind only the property of each party.

                                      A-10


     IN WITNESS WHEREOF, the Board of Directors of the Acquired Fund and the

                             SHAREHOLDER INFORMATION

The Acquiring Fund currently has four classes of shares: A Class, C Class,

MINIMUM AMOUNTS FOR ESTABLISHING ACCOUNTS

                                      B-1


The minimum initial investment amount is $100.

There is a minimum amount of $20 for subsequent investments in the Acquiring
Fund. For more information about investment minimums for subsequent investments
via Automated Clearing House ("ACH") please see "Purchase Procedures."

Rydex reserves the right to modify its minimum account balance requirements at
any rime, with or without prior notice to you.

                             TRANSACTION INFORMATION

This section provides important information about the procedures that you must
follow when you buy, sell or exchange shares of the Acquiring Fund. You may
submit transaction orders to buy, sell or exchange Acquiring Fund shares on any
day that the New York Stock Exchange (the "NYSE") is open for business (a
"Business Day"). On any day that the NYSE closes early - such as on days in
advance of holidays generally observed by the NYSE or as otherwise permitted by
the SEC - the Acquiring Fund reserves the right to advance the time that net
asset value ("NAV") is calculated and, correspondingly, the time by which
purchase and redemption orders must be received. The NYSE holiday schedule is
included in the Acquiring Fund's Statement of Additional Information and Rydex
will post advance notice of early closings at www.rydexinvestments.com.

Notwithstanding the foregoing, the Acquiring Fund reserves the right to accept
orders to purchase or redeem shares on any day that is not a Business Day and
the Federal Reserve Bank of New York or National Securities Clearing Corporation
remains open. In addition, the Acquiring Fund may designate special hours of
operation on any such day. In the event that the Acquiring Fund invokes the
right to accept orders to purchase or redeem shares on any day that is not a
Business Day and/or adopt special hours of operation, the Acquiring Fund will
post advance notice of these events at www.rydexinvestments.com.

TRANSACTION CUT-OFF TIMES

All shareholder transaction orders are processed at the NAV next determined
after your transaction order is received with all of the necessary information,
sometimes referred to as "good order," by the Acquiring Fund's transfer agent,
distributor, or authorized dealer. The following transaction cut-off times have
been established in order to allow the transfer agent appropriate time to report
the current day's trading activity to the Acquiring Fund's Advisor. Any
application that is sent to the transfer agent does not constitute a purchase
order until the transfer agent processes the application and receives correct
payment by check, wire transfer or ACH.

                          METHOD                                              CUT-OFF TIME

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

     *   Each financial intermediary may have its own rules about share
         transactions, and may have earlier cut-off times for processing your
         transaction order.


EARLY TRANSACTION CUT-OFF TIMES

On any day that the Acquiring Fund calculates NAV earlier than normal, as
described below, the transfer agent reserves the right to advance the time on
that day by which shareholder transaction orders must be received by the
transfer agent.

CALCULATING NAV

The price at which you buy, sell and exchange shares is the net asset value per
share, which is also known as NAV.

The Acquiring Fund calculates its NAV by:

     o   Taking the current market value of its total assets

     o   Subtracting any liabilities


                                      B-2


     o    Dividing that amount by the total number of shares owned by
          shareholders

The Acquiring Fund calculates NAV once each Business Day as of the regularly
scheduled close of normal trading on the NYSE (normally, 4:00 p.m., Eastern
Time). If the NYSE closes early - such as on days in advance of holidays
generally observed by the NYSE - the Acquiring Fund will calculate NAV as of the
earlier closing time in accordance with the policies set forth in the Acquiring
Fund's Statement of Additional Information. These dates are listed in the
Acquiring Fund's Statement of Additional Information. For more information on
these early closings, please call 800.820.0888 or visit the Rydex web site -
www.rydexinvestments.com.

The Acquiring Fund values its assets using the amortized cost method of
valuation pursuant to procedures approved by the Acquiring Fund's Board of
Trustees.

More information about the valuation of the Acquiring Fund's holdings and the
amortized cost method can be found in the Acquiring Fund's Statement of
Additional Information.

TRANSACTIONS THROUGH YOUR FINANCIAL INTERMEDIARY

If you opened your account through a financial intermediary, you will ordinarily
submit your transaction orders through that financial intermediary. Your
financial intermediary is responsible for ensuring that your transaction order
is in good order, and promptly transmitting your order to the Acquiring Fund.
Transaction orders received in good order by your financial intermediary will be
processed at the Acquiring Fund's next determined NAV. Financial intermediaries
may charge fees for the services they provide to you in connection with
processing your transaction order or maintaining your account with them. Each
financial intermediary may also have its own rules about minimum initial
investment amounts, minimum account balances, share transactions, limits on the
number of share transactions you are permitted to make in a given time period,
and may have different cut-off times for processing your transaction order. For
more information about your financial intermediary's rules and procedures, you
should contact your financial intermediary directly.

                               BUYING FUND SHARES

The Acquiring Fund issues its shares continuously and investors may submit
purchase orders to buy shares on any Business Day. However, the transfer agent
reserves the right to reject or refuse, in whole or in part, any purchase order
for Acquiring Fund shares within 72 hours of the transfer agent receiving the
purchase order. Purchase orders, like any other share transaction, are subject
to the Acquiring Fund's transaction cut-off times and will be processed at the
NAV next determined after your purchase order is received in good order.

PURCHASE PROCEDURES

The Acquiring Fund offers you the option to submit purchase orders through your
financial intermediary or send purchase orders by mail, fax or internet and send
purchase proceeds by check, wire transfer or ACH. The Acquiring Fund does not
accept cash or cash equivalents (such as travelers' checks, money orders or
bearer bonds), government checks, third-party checks, starter checks or checks
drawn on a line of credit (including credit card convenience checks). Cashiers
checks, bank checks, official checks and treasurers' checks less than or equal
to $10,000 are also not accepted. The transfer agent reserves the right to
refuse other payment instruments if, in the sole discretion of fund management,
it is deemed to be in the best interests of the Acquiring Fund. Any payment
instrument refused will generally be returned to you within twenty-four (24)
hours of the transfer agent's refusal to accept such instrument, but in no event
later than seventy-two (72) hours after such refusal.

Retirement contributions will be coded for the year in which they are received
unless otherwise instructed in writing at the time of the contribution.

                                      B-3


You may buy shares and send your purchase proceeds by any of the following
methods:

CANCELLED PURCHASE ORDERS

Rydex will ordinarily cancel your purchase order under the following
circumstances:

     o   if your bank does not honor your check for any reason

     o   if the transfer agent does not receive your wire transfer

     o   if the transfer agent does not receive your ACH transfer

     o   if your bank does not honor your ACH transfer

If your purchase order is cancelled for any of these reasons, you will not be
entitled to benefit from any increase in NAV that the Acquiring Fund may have
experienced from the time of your order to the time of its cancellation. In
addition, if the Acquiring Fund's NAV decreases in value from the time of your
order to the time of its cancellation, the Acquiring Fund will hold you liable
for any losses that it incurs as a result of your cancelled order.

                               SELLING FUND SHARES

The Acquiring Fund redeems its shares continuously and investors may sell their
shares back to the Acquiring Fund on any Business Day. You may redeem all or any
portion of your Acquiring Fund shares at the Acquiring Fund's next determined
NAV calculated after your redemption order is received in good order by the
transfer agent. Redemption orders, like any other share transaction, are subject
to the Acquiring Fund's transaction cut-off times and will be processed at the
NAV next determined after your redemption order is received in good order by the
transfer agent or your financial intermediary.

The Acquiring Fund may suspend your right to redeem your shares during times
when trading on the NYSE is suspended or restricted, or otherwise as permitted
by the SEC. The Acquiring Fund reserves the right to pay all or part of your
redemption proceeds in liquid securities with a market value equal to the
redemption price. If the Acquiring Fund redeems your shares in kind, you may
bear transaction costs and will bear marker risks until such time as such
securities are converted to cash.

REDEMPTION PROCEDURES

You will ordinarily submit your transaction order through your financial
intermediary or other securities dealers through which you opened your
shareholder account or through Rydex Investments directly. The Acquiring Fund
also offers you the option to send redemption orders to Rydex Investments by:

                                      B-5

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


Whether you transmit your redemption order by mail, fax or telephone, you must
include the following information in your redemption order:

     o   your name

     o   your shareholder account number

     o   Fund name(s)

     o   dollar amount or number of shares you would like to sell

     o   whether you want your sale proceeds sent to you by check, wire or ACH
         (a new alternate payee or new wire instructions may require a signature
         guarantee)

     o   signature of account owner(s) (not required for telephone redemptions)

You may only place a redemption order if you are the registered owner of the
account or the registered owner has given Rydex written authorization to allow
you to make redemptions from the account. You will receive a confirmation number
for your redemption. Please retain it for your records.

DISTRIBUTIONS FROM QUALIFIED RETIREMENT ACCOUNTS

Distributions from your tax-qualified plan or individual retirement account
("IRA") may have adverse tax consequences to you. You should consult your tax
adviser before redeeming shares and making distributions from your tax-qualified
plan or IRA account. All requests for distributions of redemption proceeds from
tax-qualified plan and IRA accounts must be in writing. All distributions from
tax-qualified plans and IRAs are subject to tax withholding rules.

RECEIVING YOUR REDEMPTION PROCEEDS

Your redemption proceeds normally will be sent within seven days of the transfer
agent receiving your request. For redemption orders that settle on federal bank
holidays, your redemption proceeds will be sent on the next Business Day
following the holiday. For investments made by check or ACH (not wire
purchases), payment of redemption proceeds may be delayed until the transfer
agent is reasonably satisfied that your purchase has cleared. It may take up to
15 days for your purchase to clear.

All redemptions will be mailed to your address of record, sent electronically,
via ACH, or wired to your bank account of record. You may request overnight mail
service for an additional fee. If you request payment of redemption proceeds to
a third parry or to a location other than your address of record or bank account
of record, your redemption request must be in writing and must include a
signature guarantee and may not be faxed.

SIGNATURE GUARANTEES

Signature guarantees help protect you and your account against fraud. You can
obtain a signature guarantee at most banks and financial intermediaries. A
notary public cannot provide a signature guarantee. You may not use fax to
transmit a signature guarantee to the Acquiring Fund.

REDEEMING SHARES BY DRAFT WRITING

If you hold shares directly, you may redeem shares from the Acquiring Fund by
writing drafts for $100 or more on your existing account. The drafts may be made
payable to any person or entity and your account will continue to earn dividends
until the draft clears. Drafts may not be used for electronic funds transfers
(i.e., electronic bill

                                      B-6


payments or ACH). If your balance in the Acquiring Fund is insufficient to cover
the amount of your draft, the transfer agent will return it as insufficient
funds.

You can obtain a draft writing application by calling [800.820.0888]. Because of
the difficulty of determining in advance the exact value of your Acquiring Fund
account, you may not use a draft to close your account. There is no fee for the
draft writing privilege, but if payment on a draft is stopped upon your request,
or if the draft cannot be honored because of insufficient funds or other valid
reasons, you may be charged a fee by the financial institution where you
presented your draft for payment. The transfer agent may also charge a $25 fee
for a draft than cannot be honored due to insufficient funds. The Acquiring Fund
may suspend the draft writing privilege at any time.

                             EXCHANGING FUND SHARES

As described herein, an exchange is when you sell shares of the Fund and use the
proceeds from that sale to purchase shares of a Security Fund. The Security
Funds include each share class of the Security Equity Fund (and each of its
series); the Security Income Fund (and each of its series); the Security Large
Cap Value Fund (and each of its series); and the Security Mid Cap Growth Fund.
Investors may make exchanges on any Business Day of the Fund for shares of any
Security Fund on the basis of the respective NAVs of the shares involved.
Exchange requests, like any other share transaction, will be processed at the
NAV next determined after your exchange order is received in good order. All
exchange requests must be received by the Fund's transfer agent or your
financial intermediary prior to the cut-off time of the Fund or the Security
Fund you are exchanging into, whichever is earlier, to be processed at that
Business Day's NAV. See "Exchanges with Security Funds" for additional
information. The exchange privilege may be modified or discontinued at any time.
If it is determined that a shareholders' transfer patterns among the Fund and
the Security Funds are disruptive or potentially disadvantageous to other
shareholders, the Fund will send the shareholder a letter notifying the
shareholder that the Fund is prohibiting the shareholder from making any
additionally purchases for a 90-day period that begins on the date of the
letter. This restriction will be applied after the shareholder makes four "round
trip transfers" during any 12-month period. A "round trip transfer" is a
transfer (1) from the Fund followed by a transfer to the Fund or (2) to the Fund
followed by a transfer from the Fund.

EXCHANGE PROCEDURES

You will ordinarily submit your transaction order through your financial
intermediary or other securities dealers through which you opened your
shareholder account or through Rydex Investments directly. The Acquiring Fund
also offers you the option to send exchange requests by:

EXCHANGES WITH SECURITY FUNDS

Security Fund, which are offered in a separate prospectus. IF YOU ARE
CONTEMPLATING AN EXCHANGE FOR SHARES OF THE FUND FOR SHARES OF ANY SECURITY
FUND, YOU SHOULD OBTAIN AND REVIEW THAT SECURITY FUND'S CURRENT PROSPECTUS
BEFORE MAKING THE EXCHANGE. You may obtain a prospectus for any Security Fund by

                             RYDEX ACCOUNT POLICIES

SHAREHOLDER IDENTIFICATION AND VERIFICATION

Federal regulations may require the Acquiring Fund to obtain your name, your
date of birth (for a natural person), your residential street address or
principal place of business and your Social Security Number, Employer
Identification Number or other government issued identification when you open an
account. Additional information may be required in certain circumstances or to
open accounts for corporations or other entities. The Acquiring Fund may use
this information to attempt to verify your identity. The Acquiring Fund may not
be able to establish an account if the necessary information is not received.
The Acquiring Fund may also place limits on account transactions while it is in
the process of attempting to verify your identity. Additionally, if the
Acquiring Fund is unable to verify your identity after your account is
established, the Acquiring Fund may be required to redeem your shares and close
your account.

Rydex provides accounts for U.S. citizens and resident aliens. We will not open
a new account for any non-resident aliens (natural person or entity). If you are
unsure of your status please consult your tax adviser. Non-resident aliens may
hold Rydex Funds through a financial intermediary, subject to that financial
intermediary's requirements.

                                      B-8


Customer identification and verification is part of the Acquiring Fund's overall
obligation to deter money laundering under applicable law. The Acquiring Fund
has adopted an anti-money laundering compliance program designed to prevent the
Acquiring Fund from being used for money laundering or the financing of
terrorist activities. In this regard, the Acquiring Fund reserves the right to
(i) refuse, cancel or rescind any purchase or exchange order, (ii) freeze any
account and/or suspend account services or (iii) involuntarily close your
account in cases of threatening conduct or suspected fraudulent or illegal
activity. These actions will be taken when, in the sole discretion of Fund
management, they are deemed to be in the best interests of the Acquiring Fund or
in cases when the Acquiring Fund is requested or compelled to do so by
governmental or law enforcement authority. If your account is closed at the
request of governmental or law enforcement authority, you may not receive
proceeds of the redemption if the Acquiring Fund is required to withhold such
proceeds.

CHANGES TO YOUR ACCOUNT

For information on what is required to make changes and/or additions to your
account, and to obtain the appropriate forms, please visit the Rydex web site at
www.rydexinvestments.com or call [800.820.0888] or [301.296.5406]. If you own
shares that are registered in your intermediary's name, and you want to transfer
the registration to another intermediary or want the shares registered in your
name, then you should contact your intermediary for instructions on how to make
this change.

TRANSACTIONS OVER TELEPHONE OR INTERNET

Internet and telephone transactions are extremely convenient, but are not risk
free. To ensure that your internet and telephone transactions are safe, secure,
and as risk-free as possible, the Acquiring Fund has instituted certain
safeguards and procedures for determining the identity of web site users
(including the use of secure passwords and 128-bit encryption technology) and
telephone callers and authenticity of instructions. As a result, neither the
Acquiring Fund nor its transfer agent will be responsible for any loss,
liability, cost, or expense for following internet, telephone or wire
instructions they reasonably believe to be genuine. If you or your
intermediaries make exchange requests by telephone or internet, you will
generally bear the risk of any loss. Neither the Acquiring Fund, nor its
transfer agent, is responsible for internet transactions that are not received.

During periods of unusually high market activity or other times, it may be
difficult to reach Rydex by telephone or access our internet site. Rydex
Investments and its affiliates will not be liable for any losses resulting from
a cause over which Rydex Investments or its affiliates do nor have direct
control, including but not limited to the failure of electronic or mechanical
equipment or communication lines, telephone or other interconnect problems
(e.g., if you are unable to access your online service provider), input errors
on the internet, severe weather, facilities emergencies, earthquakes, floods and
strikes or other labor problems. If you are not able to reach Rydex Client
Services by your regular medium, consider sending written instructions.

You will receive statements and trade confirmations of your investment
transactions.

with the following:

     o    $20 for wire transfers of redemption proceeds

     o    $50 on purchase checks returned for insufficient funds

     o    $25 to stop payment of a redemption check within 10 Business Days of
          the settlement date

     o    $20 for standard overnight packages (fee may be higher for special
          delivery options)

                                      B-9


     o    $25 for bounced drafts or ACH Transactions

     o    The Acquiring Fund reserves the right, upon notice, to charge you a
          fee to cover the costs of special requests for information that
          require extensive research or employee resources. Such requests could
          include a request for historical account transcripts or the retrieval
          of a significant number of documents.

Rydex reserves the right to change any of these fees or add additional service
fees at any time.

RETIREMENT ACCOUNT FEES

Certain retirement plans such as IRA, SEP, Roth IRA and 403(b) accounts, are
charged an annual $10 maintenance fee. You may pay the annual maintenance fee at
any time during the calendar year by sending Rydex Investments a check. If the
annual maintenance fee is not paid separately prior to December, it will be
deducted from your account.

RIGHTS RESERVED BY THE ACQUIRING FUND

The Acquiring Fund reserves the right to close your account in cases of
suspected fraudulent or illegal activity in accordance with applicable law. This
action may be taken when, in the sole discretion of Rydex Investments, it is
deemed to be in the best interests of the Acquiring Fund or in cases where the
Acquiring Fund is requested or compelled to do so by applicable law. If your
account is closed at the request of governmental or law enforcement authority or
pursuant to applicable law, you may not receive proceeds of the redemption if
the Acquiring Fund is required to withhold such proceeds.

                      DISTRIBUTION AND SHAREHOLDER SERVICES

COMPENSATION TO DEALERS

The Advisor, at its expense, may provide compensation to financial
intermediaries for the sale of Fund shares. These payments may be made, at the
discretion of the Advisor, to certain dealers who have sold shares of the Fund.
The level of payments made to dealers will generally vary, but may be
significant. These payments may provide an incentive for dealers to sell shares
of the Fund and promote the retention of their customer's assets in the Fund.
Any payments described above will not change the price paid by investors for the
purchase of the Fund's shares or the amount that any particular Fund will
receive as proceeds from such sales. The Advisor determines the extent of such
payments in its sole discretion in response to requests from dealer firms, based
on factors it deems relevant, such as the dealer's sales, assets, share class
utilized and the quality of the dealer's relationship with the Advisor. The
Advisor periodically determines the advisability of continuing these payments.
The Advisor may also pay expenses associated with meetings that facilitate
educating financial advisers and shareholders about the Fund that are conducted
by dealers.

                           DIVIDENDS AND DISTRIBUTIONS

TIMING OF PAYMENTS

The Acquiring Fund will declare dividends daily and pay them monthly or upon
redemption. If you own Acquiring Fund shares on the Acquiring Fund's record
date, you will be entitled to receive the dividend. The Acquiring Fund may
declare and pay dividends on the same date. The Acquiring Fund makes
distributions of capital gains, if any, at least annually. The Acquiring Fund,
however, may declare a special capital gains distribution if the Board of
Trustees believes that such a distribution would be in the best interests of the
shareholders of the Acquiring Fund.

DIVIDEND PAYMENT OPTIONS

Dividends and distributions will he paid in the form of additional Acquiring
Fund shares unless you have elected to receive payment in cash. If you did not
elect to receive cash payments of dividends and distributions on your
application, you must notify the Acquiring Fund in writing to change your
election prior to the date of the next distribution. Your election will become
effective for dividends paid after the Acquiring Fund receives your written
notice. To cancel your election, simply send written notice to the Acquiring
Fund. Dividends and distributions with values of $10 or less may be
automatically reinvested.

                                 TAX INFORMATION

The following is a summary of some important tax issues that affect the
Acquiring Fund and its shareholders. The summary is based on current tax laws,
which may be changed by legislative, judicial or administrative action. You
should not consider this summary to he a detailed explanation of the tax
treatment of the Acquiring Fund, or the tax consequences of an investment in the
Acquiring Fund. MORE INFORMATION ABOUT TAXES IS LOCATED IN THE ACQUIRING FUND'S
STATEMENT OF ADDITIONAL INFORMATION. YOU ARE URGED TO CONSULT YOUR TAX ADVISER
REGARDING SPECIFIC QUESTIONS AS TO FEDERAL, STATE AND LOCAL INCOME TAXES.

TAX STATUS OF THE ACQUIRING FUND

The Acquiring Fund is treated as a separate entity for federal tax purposes, and
intends to qualify for the special tax treatment afforded to regulated
investment companies. As long as the Acquiring Fund qualifies as a regulated
investment company, it pays no federal income tax on the earnings it distributes
to shareholders.

TAX STATUS OF DISTRIBUTIONS

     o   The Acquiring Fund will, at least annually, distribute substantially
         all of its net investment income and net capital gains income.

     o   The income dividends and short-term capital gains distributions you
         receive from the Acquiring Fund will be taxed as either ordinary income
         or qualified dividend income. Dividends that are qualified dividend
         income are eligible for the reduced maximum rare to individuals of 15%
         (lower rates apply to individuals in lower tax brackets) to the extent
         that the Acquiring Fund receives qualified dividend income. The
         Acquiring Fund does not expect to make distributions that will be
         treated as qualified dividend income.

     o   Any long-term capital gains distributions you receive from the
         Acquiring Fund are taxable as long-term capital gains regardless of how
         long you have owned your shares. Long-term capital gains are currently
         taxed at a maximum rate of 15%. The Acquiring Fund does not expect to
         distribute any long-term capital gains.

     o   Absent further legislation, the maximum 15% tax rare on qualified
         dividend income and long-term capital gains will cease to apply to
         taxable years beginning after December 31, 2010.

     o   Dividends and distributions are generally taxable to you whether you
         receive them in cash or in additional shares.

     o   Corporate shareholders may be entitled to a dividends-received
         deduction for the portion of dividends they receive that are
         attributable to dividends received by the Acquiring Fund from U.S.
         corporations, subject to certain limitations.

     o   The Acquiring Fund does not expect to make any distributions of
         dividends qualified for the dividends-received deduction.

     o   Distributions paid in January but declared by the Acquiring Fund in
         October, November or December of the previous year may be taxable to
         you in the previous year.

     o   The Acquiring Fund will inform you of the amount of distributions
         shortly after the close of each calendar year. It is expected that all
         distributions from the Acquiring Fund will be ordinary income.

     o   If you hold your shares in a tax-qualified retirement account, you
         generally will not be subject to federal taxation on Fund distributions
         until you begin receiving distributions from your retirement account.
         You should consult your tax adviser regarding the tax rules that apply
         to your retirement account.

TAX STATUS OF SHARE TRANSACTIONS

EACH SALE, EXCHANGE, OR REDEMPTION OF ACQUIRING FUND SHARES MAY BE A TAXABLE
EVENT TO YOU. There will be no gain or loss on a sale, exchange or redemption of
shares of the Acquiring Fund so long as the Acquiring Fund shares maintain a
stable price per share of $1.00. For tax purposes, an exchange of Acquiring Fund
shares for shares of a

                                      B-11


Security Fund is treated the same as a sale. You should consider the tax
consequences of any redemption or exchange before making such a request,
especially with respect to redemptions if you invest in the Acquiring Fund
through a tax-qualified retirement plan.

STATE TAX CONSIDERATIONS

The Acquiring Fund is not liable for any income or franchise tax in Delaware as
long as it qualifies as a regulated investment company for federal income tax
purposes. In addition to federal taxes, distributions by the Acquiring Fund and
ownership of Acquiring Fund shares may be subject to state and local taxes. You
should consult your tax adviser regarding how share and local tax laws affect
your investment in Acquiring Fund shares.

                                OTHER INFORMATION

Item 15       Indemnification
-------       ---------------

Rydex Series Funds (the "Registrant" or the "Trust") is organized as a Delaware
statutory trust and is operated pursuant to a Declaration of Trust, dated as of
March 13, 1993, as amended (the "Declaration of Trust"), that permits the
Registrant to indemnify its trustees and officers under certain circumstances.
Such indemnification, however, is subject to the limitations imposed by the
Securities Act of 1933, as amended, and the Investment Company Act of 1940, as
amended. The Registrant's Declaration of Trust provides that officers and
trustees of the Trust shall be indemnified by the Trust against liabilities and
expenses of defense in proceedings against them by reason of the fact that they
each serve as an officer or trustee of the Trust or as an officer or trustee of
another entity at the request of the entity. This indemnification is subject to
the following conditions:

(a) no trustee or officer of the Trust is indemnified against any liability to
the Trust or its security holders which was the result of any willful
misfeasance, bad faith, gross negligence, or reckless disregard of his duties;

(b) officers and trustees of the Trust are indemnified only for actions taken in
good faith which the officers and trustees believed were in or not opposed to
the best interests of the Trust; and

(c) expenses of any suit or proceeding will be paid in advance only if the
persons who will benefit by such advance undertake to repay the expenses unless
it subsequently is determined that such persons are entitled to indemnification.

The Registrant's Declaration of Trust provides that if indemnification is not
ordered by a court, indemnification may be authorized upon determination by
shareholders, or by a majority vote of a quorum of the trustees who were not
parties to the proceedings or, if this quorum is not obtainable, if directed by
a quorum of disinterested trustees, or by independent legal counsel in a written
opinion, that the persons to be indemnified have met the applicable standard.

      of this registration statement by any person or party who is deemed to be
      an underwriter within the meaning of Rule 145(c) of the Securities Act (17
      CFR 230.145(c)), the reoffering prospectus will contain the information
      called for by the applicable registration form for reofferings by persons
      who may be deemed underwriters, in addition to the information called for
      by the other items of the applicable form.

2.    The undersigned registrant agrees that every prospectus that is filed
      under paragraph (1) above will be filed as a part of an amendment to the
      registration statement and will not be used until the amendment is
      effective, and that, in determining any liability under the 1933 Act, each
      post-effective amendment shall be deemed to be a new registration
      statement for the securities offered therein, and the offering of the
      securities at that time shall be deemed to be the initial bona fide
      offering of them.

3.    The undersigned registrant undertakes to file a post-effective amendment
      to this registration statement upon the closing of the Reorganization
