SECURITY INCOME FUND
   
  o CORPORATE BOND SERIES                PROSPECTUS
  o LIMITED MATURITY BOND SERIES         MAY 1, 1998
  o U.S. GOVERNMENT SERIES
  o HIGH YIELD SERIES

SECURITY MUNICIPAL BOND FUND
    
SECURITY CASH FUND

MEMBERS OF THE SECURITY BENEFIT GROUP OF COMPANIES, 
700 HARRISON, TOPEKA, KANSAS 66636-0001

   The investment objective of the CORPORATE BOND SERIES ("Corporate Bond Fund")
is  conservation  of principal  while  generating  interest  income by investing
primarily  in  a  diversified  portfolio  of  investment  grade  corporate  debt
securities.  The  investment  objective  of the  LIMITED  MATURITY  BOND  SERIES
("Limited Maturity Bond Fund") is to seek a high level of income consistent with
moderate   price   fluctuation   by   investing    primarily   in   short-   and
intermediate-term  debt  securities.   The  investment  objective  of  the  U.S.
GOVERNMENT  SERIES  ("U.S.  Government  Fund")  is to  provide  a high  level of
interest income with security of principal by investing  primarily in securities
which  are  guaranteed  or  issued  by the  U.S.  Government,  its  agencies  or
instrumentalities.  The  investment  objective of the HIGH YIELD  SERIES  ("High
Yield Fund") is to seek high current income. Capital appreciation is a secondary
objective.  The Fund seeks to achieve its objective by investing  primarily in a
broad  range of income  producing  securities,  including  domestic  and foreign
high-yield,  lower rated debt  securities.  THE FUND INVESTS  PRIMARILY (AND MAY
INVEST UP TO 100% OF ITS ASSETS) IN LOWER RATED BONDS,  COMMONLY  KNOWN AS "JUNK
BONDS," THAT ENTAIL GREATER RISKS,  INCLUDING DEFAULT RISKS, THAN THOSE FOUND IN
HIGHER RATED SECURITIES.  INVESTORS SHOULD CAREFULLY CONSIDER THESE RISKS BEFORE
INVESTING.  SEE "INVESTMENT  METHODS AND RISK FACTORS" - "RISKS  ASSOCIATED WITH
LOWER RATED DEBT SECURITIES" ON PAGE 19.
   
   The investment  objective of SECURITY  MUNICIPAL BOND FUND  ("Municipal  Bond
Fund")  (formerly  Security  Tax-Exempt  Fund) is to  obtain  as high a level of
interest  income exempt from regular  federal income taxes as is consistent with
preservation of stockholders'  capital by investing primarily in debt securities
which are  exempt  from  federal  income  tax.  Except at times when the Fund is
invested  defensively,  at least 80 percent of its total assets will be invested
in  securities  exempt  from  federal  income  taxes.  The  Fund may  invest  in
securities  which  generate  income that is subject to the  federal  alternative
minimum tax.
    
   The  investment  objective of SECURITY  CASH FUND ("Cash Fund") is to earn as
high a level of current income as is consistent with preservation of capital and
liquidity through investments in money market instruments with maturities of not
longer than thirteen  months.  AN INVESTMENT IN CASH FUND IS NEITHER INSURED NOR
GUARANTEED BY THE U.S.  GOVERNMENT  AND THERE CAN BE NO ASSURANCE THAT CASH FUND
WILL BE ABLE TO MAINTAIN A STABLE NET ASSET VALUE OF $1.00 PER SHARE.

1  Class B shares convert tax-free to Class A shares  automatically  after eight
   years.

2  Purchases of Class A shares in amounts of  $1,000,000 or more are not subject
   to an initial sales load;  however, a contingent  deferred sales charge of 1%
   is imposed in the event of redemption within one year of purchase. See "Class
   A Shares" on page 23.

3  During the fiscal year ended December 31, 1997, the Investment Manager waived
   the investment  advisory fees of the Limited  Maturity Bond, U.S.  Government
   and High Yield Funds and,  during the fiscal year  ending  December  31, 1998
   will  waive the  investment  advisory  fees of such  Funds;  absent  such fee
   waivers,  "Management  Fees" would have been as follows:  .5% for each of the
   Limited  Maturity Bond and U.S.  Government  Funds and .6% for the High Yield
   Fund.

4  Long-term  holders of shares that are subject to an asset-based  sales charge
   may pay more  than the  equivalent  of the  maximum  front-end  sales  charge
   otherwise permitted by NASD Rules.

5  During the fiscal  year ended  December  31,  1997,  the  Investment  Manager
   reimbursed certain expenses of the Funds. Absent such  reimbursement,  "Other
   Expenses"  would have been as follows:  ___% for Class B shares of  Corporate
   Bond Fund;  ___% for Class B shares of Limited  Maturity Bond Fund;  ___% for
   Class B shares  of U.S.  Government  Fund;  and ___%  for  Class B shares  of
   Municipal Bond Fund.

6  During the fiscal year ended December 31, 1997, the Investment Manager waived
   and/or  reimbursed  certain expenses of the Funds and, during the fiscal year
   ending  December 31, 1998 will waive the investment  advisory fees of Limited
   Maturity  Bond,   U.S.   Government   and  High  Yield  Funds.   Absent  such
   reimbursement and waiver,  "Total Fund Operating Expenses" would have been as
   follows:  ___% for Class A shares  and ___% for  Class B shares of  Corporate
   Bond  Fund;  ___% for Class A shares  and ___% for Class B shares of  Limited
   Maturity  Bond  Fund;  ___% for Class A shares and ___% for Class B shares of
   U.S.  Government Fund; ___% for Class A shares and ___% for Class B shares of
   High  Yield  Fund;  and ___%  for  Class A and  ___%  for  Class B shares  of
   Municipal Bond Fund.
    
THE ABOVE EXAMPLES SHOULD NOT BE CONSIDERED A  REPRESENTATION  OF PAST OR FUTURE
EXPENSES  AS ACTUAL  EXPENSES  MAY BE GREATER OR LESSER  THAN THOSE  SHOWN.  THE
ASSUMED FIVE PERCENT ANNUAL RETURN IS HYPOTHETICAL  AND SHOULD NOT BE CONSIDERED
A  REPRESENTATION  OF PAST OR FUTURE  ANNUAL  RETURN.  THE ACTUAL  RETURN MAY BE
GREATER OR LESSER THAN THE ASSUMED AMOUNT.

   The  purpose  of the  foregoing  fee  table  is to  assist  the  investor  in
understanding the various costs and expenses that an investor in Corporate Bond,
Limited Maturity Bond, U.S. Government, High Yield, Municipal Bond or Cash Funds
will bear directly or indirectly.  For a more detailed  discussion of the Funds'
fees and expenses,  see the discussion under "Management of the Funds," page 20.
Information on the Funds' 12b-1 Plans may be found under the headings  "Security
Income and  Municipal  Bond Funds'  Class A  Distribution  Plans" on page 24 and
"Class B Distribution  Plan" on page 25. See "How to Purchase  Shares," page 22,
for more  information  concerning  the sales load.  Also,  see  Appendix C for a
discussion  of "Rights of  Accumulation"  and  "Statement of  Intention,"  which
options may serve to reduce the  front-end  sales load on  purchases  of Class A
Shares.

SECURITY FUNDS
PROSPECTUS
================================================================================
INVESTMENT OBJECTIVES AND POLICIES OF THE FUNDS
   
   Security  Income,  Municipal  Bond and Cash  Funds are  diversified  open-end
management investment companies,  which were organized as Kansas corporations on
September 9, 1970, July 14, 1981, and March 21, 1980, respectively.  Each of the
Corporate Bond Fund,  Limited Maturity Bond Fund, U.S.  Government Fund and High
Yield Fund, series of Security Income Fund, and Security Municipal Bond Fund and
Cash Fund  (collectively,  "the  Funds") has its own  investment  objective  and
policies which are described below.  There, of course,  can be no assurance that
such investment objectives will be achieved. While there is no present intention
to do so, the  investment  objective and policies of each Fund may be changed by
the Board of  Directors  of the Funds  without  the  approval  of  stockholders.
However,  stockholders  will be given 30 days written notice of any such change.
If a change  in  investment  objective  is made,  stockholders  should  consider
whether  the Fund  remains  an  appropriate  investment  in light of their  then
current financial position and needs.

   Each of the Funds is also subject to certain  investment policy  limitations,
which may not be changed without stockholder approval.  Among these limitations,
some of the more  important  ones are that each Fund will not invest more than 5
percent  of the  value  of its  assets  in any one  issuer  other  than the U.S.
Government or its  instrumentalities  (for Cash,  Municipal  Bond and High Yield
Funds,  this limitation  applies only with respect to 75 percent of the value of
its total  assets),  purchase  more than 10  percent of the  outstanding  voting
securities of any one issuer or invest 25 percent or more of its total assets in
any one industry.  The Municipal  Bond Fund will not invest more than 20 percent
of its  assets in  securities  that are not  tax-exempt  securities,  except for
temporary  defensive  purposes.  In  addition,  the full text of the  investment
policy  limitations  of each  Fund  is set  forth  in the  Funds'  Statement  of
Additional Information.
    
   Each of the Funds may  borrow  money from banks as a  temporary  measure  for
emergency purposes or to facilitate redemption requests. See "Investment Methods
and  Risk  Factors"  for  a  discussion  of  borrowing.  Pending  investment  in
securities  or to meet  potential  redemptions,  each of the Funds may invest in
certificates of deposit,  bank demand accounts,  repurchase  agreements and high
quality money market instruments.

SECURITY INCOME FUND

   Security Income Fund ("Income  Fund") is a series  investment  company,  with
each Series  representing  a different  investment  objective and having its own
identified assets and net asset values.  The investment  objectives of Corporate
Bond,  Limited  Maturity  Bond,  U.S.  Government  and High Yield Funds are each
described below.

CORPORATE BOND FUND

   The investment  objective of Corporate Bond Fund is to preserve capital while
generating interest income. In pursuing its investment objective,  the Fund will
invest in a broad range of debt securities,  including (i) securities  issued by
U.S. and Canadian corporations; (ii) securities issued or guaranteed by the U.S.
Government  or any of its  agencies  or  instrumentalities,  including  Treasury
bills, certificates of indebtedness, notes and bonds; (iii) securities issued or
guaranteed  by the  Dominion of Canada or  provinces  thereof;  (iv)  securities
issued by foreign governments, their agencies and instrumentalities, and foreign
corporations, provided that such securities are denominated in U.S. dollars; (v)
higher  yielding,  high  risk debt  securities  (commonly  referred  to as "junk
bonds");  (vi) certificates of deposit issued by a U.S. branch of a foreign bank
("Yankee CDs"); and (vii) investment grade mortgage backed securities  ("MBSs").
Under normal circumstances,  at least 65 percent of the Fund's total assets will
be invested in corporate  debt  securities  which at the time of issuance have a
maturity greater than one year.

   Corporate Bond Fund will invest  primarily in corporate debt securities rated
Baa or higher by Moody's Investors Service, Inc. ("Moody's") or BBB or higher by
Standard & Poor's Corporation ("S&P") at the time of purchase, or if unrated, of
equivalent  quality as determined by the Investment  Manager.  See Appendix A to
this  Prospectus for a description  of corporate bond ratings.  Included in such
securities  may be convertible  bonds or bonds with warrants  attached which are
rated at least Baa or BBB at the time of purchase,  or if unrated, of equivalent
quality as determined by the Investment Manager. A "convertible bond" is a bond,
debenture  or  preferred  share which may be  exchanged  by the owner for common
stock or another security,  usually of the same company,  in accordance with the
terms of the issue. A "warrant" confers upon its holder the right to purchase an
amount of securities  at a particular  time and price.  Securities  rated Baa by
Moody's or BBB by S&P have speculative characteristics.  See "Investment Methods
and Risk Factors" for a discussion of the risks associated with such securities.

PROSPECTUS
================================================================================
   Corporate  Bond Fund may  invest up to 25 percent of its net assets in higher
yielding  debt  securities in the lower rating  (higher risk)  categories of the
recognized  rating  services  (commonly  referred  to  as  "junk  bonds").  Such
securities include securities rated Ba or lower by Moody's or BB or lower by S&P
and are regarded as predominantly speculative with respect to the ability of the
issuer to meet principal and interest payments. The Fund will not invest in junk
bonds  which are  rated in  default  at the time of  purchase.  See  "Investment
Methods  and  Risk  Factors"  for a  discussion  of the  risks  associated  with
investing in such securities.

   The Fund may purchase  securities which are obligations of, or guaranteed by,
the  Dominion  of Canada or  provinces  thereof  and debt  securities  issued by
Canadian  corporations.  Canadian securities will not be purchased if subject to
the foreign interest equalization tax and unless payable in U.S. dollars.

   The Fund may invest in Yankee CDs which are certificates of deposit issued by
a U.S. branch of a foreign bank denominated in U.S. dollars and held in the U.S.
Yankee CDs are subject to somewhat  different  risks than are the obligations of
domestic banks.  The Fund also may invest in debt  securities  issued by foreign
governments,  their  agencies and  instrumentalities  and foreign  corporations,
provided  that such  securities  are  denominated  in U.S.  dollars.  The Fund's
investment in foreign securities, including Canadian securities, will not exceed
25 percent of the Fund's net assets.  See "Investment  Methods and Risk Factors"
for a discussion of the risks associated with investing in foreign securities.

   The Fund may invest in investment  grade mortgage backed  securities  (MBSs),
including  mortgage   pass-through   securities  and   collateralized   mortgage
obligations  (CMOs).  The Fund may  invest up to 10 percent of its net assets in
securities known as "inverse floating  obligations,"  "residual interest bonds,"
or  "interest-only"  (IO) or  "principal-only"  (PO) bonds, the market values of
which  generally  will be more volatile than the market values of most MBSs. The
Fund will hold less than 25 percent of its net assets in MBSs.  For a discussion
of MBSs and the risks associated with such securities,  see "Investment  Methods
and Risk Factors."

   The Fund may invest in zero coupon  securities which are debt securities that
pay no cash income but are sold at substantial  discounts from their face value.
Certain  zero coupon  securities  also provide for the  commencement  of regular
interest payments at a deferred date. See "Investment  Methods and Risk Factors"
for a discussion of zero coupon securities.

   Corporate Bond Fund may purchase  securities on a  "when-issued"  or "delayed
delivery"  basis in  excess of  customary  settlement  periods  for the types of
security involved. For a discussion of such securities,  see "Investment Methods
and Risk Factors." It is anticipated  that  securities  invested in by this Fund
will be held by the Fund on an  average  from one and a half to three  years and
that the average weighted  maturity of the Fund's portfolio will range from 5 to
15 years under normal circumstances.

LIMITED MATURITY BOND FUND

   The investment  objective of the Limited Maturity Bond Fund is to seek a high
level  of  income  consistent  with  moderate  price  fluctuation  by  investing
primarily in short- and intermediate-term bonds. As used herein the term "short-
and  intermediate-term  bonds"  is used to  describe  any debt  security  with a
maturity of 15 years or less.  In pursuing its  investment  objective,  the Fund
will invest in a broad range of debt securities, including (i) securities issued
by U.S. and Canadian  corporations;  (ii) securities issued or guaranteed by the
U.S. Government or any of its agencies or instrumentalities,  including Treasury
bills, certificates of indebtedness, notes and bonds; (iii) securities issued or
guaranteed  by, the Dominion of Canada or  provinces  thereof;  (iv)  securities
issued by foreign governments, their agencies and instrumentalities, and foreign
corporations, provided that such securities are denominated in U.S. dollars; (v)
higher  yielding,  high  risk debt  securities  (commonly  referred  to as "junk
bonds");  (vi) certificates of deposit issued by a U.S. branch of a foreign bank
("Yankee CDs"); (vii) investment grade mortgage backed securities ("MBSs");  and
(viii)  investment grade  asset-backed  securities.  High yield debt securities,
Yankee CDs, MBSs and  asset-backed  securities  are described in further  detail
under  "Investment  Methods and Risk Factors." Under normal  circumstances,  the
Fund will invest at least 65 percent of the value of its total  assets in short-
and intermediate-term  bonds. It is anticipated that the dollar weighted average
maturity  of the Fund's  portfolio  will  range from 2 to 10 years.  It will not
exceed 10 years.

   Limited Maturity Bond Fund will invest primarily in debt securities rated Baa
or higher by  Moody's  or BBB or  higher by S&P at the time of  purchase,  or if
unrated,  of equivalent  quality as determined by the  Investment  Manager.  See
Appendix A to this  Prospectus  for a  description  of corporate  bond  ratings.
Included in such  securities  may be  convertible  bonds or bonds with  warrants
attached  which  are rated at least  Baa or BBB at the time of  purchase,  or if
unrated,  of  equivalent  quality as  determined by the  Investment  Manager.  A
"convertible  bond"  is a  bond,  debenture  or  preferred  share  which  may be
exchanged,  by the owner, for common stock or another  security,  usually of the
same company,  in accordance  with the terms of the issue.  A "warrant"  confers
upon its holder the right to purchase an amount of  securities  at a  particular
time and price.  Securities  rated Baa by Moody's or BBB by S&P have speculative
characteristics as described under "Investment  Methods and Risk  Factors"--"Baa
or BBB Securities."

PROSPECTUS
================================================================================
   The Fund may invest in higher  yielding  debt  securities in the lower rating
(higher risk) categories of the recognized rating services (commonly referred to
as "junk  bonds");  however,  the Fund will not hold more than 25 percent of its
net assets in junk bonds. This includes  securities rated Ba or lower by Moody's
or BB or lower  by S&P,  and  such  securities  are  regarded  as  predominantly
speculative  with  respect to the  ability of the issuer to meet  principal  and
interest  payments.  The Fund will not invest in junk  bonds  which are rated in
default at the time of purchase. See "Investment Methods and Risk Factors" for a
discussion of the risks associated with investing in such securities.

   For the year ended December 31, 1997, the dollar weighted  average of Limited

The  foregoing  table is intended  solely to provide  disclosure  about  Limited
Maturity Bond Fund's asset composition for the year ended December 31, 1997. The
asset  composition  after this may or may not be approximately the same as shown
above.

   The Fund may purchase  securities which are obligations of, or guaranteed by,
the  Dominion  of Canada or  provinces  thereof  and debt  securities  issued by
Canadian  corporations.  Canadian securities will not be purchased if subject to
the foreign interest equalization tax and unless payable in U.S. currency.

   The Fund may invest in Yankee CDs which are certificates of deposit issued by
a U.S.  branch of a foreign  bank  denominated  in U.S.  dollars and held in the
United States.  Yankee CDs are subject to somewhat  different risks than are the
obligations  of  domestic  banks.  The Fund may also  invest in debt  securities
issued by foreign governments, their agencies and instrumentalities, and foreign
corporations, provided that such securities are denominated in U.S. dollars. The
Fund's investment in foreign securities, including Canadian securities, will not
exceed 25  percent  of the  Fund's net  assets.  For a  discussion  of the risks
associated with foreign securities, see "Investment Methods and Risk Factors."

   The Fund may invest in U.S. Government securities. U.S. Government securities
include  bills,  certificates  of  indebtedness,  notes and bonds  issued by the
Treasury or by  agencies  or  instrumentalities  of the U.S.  Government.  For a
discussion of the varying levels of guarantee  associated with particular  types
of U.S.  Government  Securities,  see  "Investment  Methods and Risk Factors" --
"U.S. Government Securities."

   Limited Maturity Bond Fund may acquire certain securities that are restricted
as to  disposition  under  the  federal  securities  laws,  provided  that  such
securities are eligible for resale to qualified institutional investors pursuant
to Rule 144A under the  Securities Act of 1933, and subject to the Fund's policy
that not more than 15  percent of the Fund's  net  assets  will be  invested  in
illiquid assets.  See "Investment  Methods and Risk Factors" for a discussion of
Rule 144A Securities.

   The Fund may invest in investment  grade mortgage backed  securities  (MBSs),
including  mortgage   pass-through   securities  and   collateralized   mortgage
obligations  (CMOs).  The Fund may  invest up to 10 percent of its net assets in
securities known as "inverse floating  obligations,"  "residual interest bonds,"
and "interest-only" (IO) and  "principal-only"  (PO) bonds, the market values of
which will  generally be more volatile than the market values of most MBSs.  The
Fund will hold less than 25 percent of its net  assets in MBSs,  including  CMOs
and mortgage  pass-through  securities.  For a discussion  of MBSs and the risks
associated with such securities, see "Investment Methods and Risk Factors."

   The Fund may also invest in investment grade "asset-backed securities." These
include secured debt instruments backed by automobile loans,  credit card loans,
home equity loans,  manufactured  housing loans and other types of secured loans
providing the source of both principal and interest. Asset-backed securities are
subject  to  risks  similar  to  those  discussed  with  respect  to  MBSs.  See
"Investment Methods and Risk Factors."

   The Fund may invest in zero coupon  securities which are debt securities that
pay no cash income but are sold at substantial  discounts from their face value.
Certain  zero coupon  securities  also provide for the  commencement  of regular

customary settlement periods for the type of security involved.  See "Investment

   From time to time,  Limited  Maturity Bond Fund may invest part or all of its
assets in commercial notes or money market instruments.

U.S. GOVERNMENT FUND

   The  investment  objective of the U.S.  Government  Fund is to provide a high
level of interest  income with  security of principal by investing  primarily in
U.S.  Government   securities.   U.S.   Government   securities  include  bills,
certificates  of  indebtedness,  notes and bonds  issued by the  Treasury  or by
agencies   or   instrumentalities   of  the  U.S.   Government.   Under   normal
circumstances,  the Fund  will  invest at least 80  percent  of the value of its
total assets in U.S.  Government  securities.  For a  discussion  of the varying
levels  of  guarantee  associated  with  particular  types  of  U.S.  Government
Securities,  see  "Investment  Methods and Risk  Practices" -- "U.S.  Government
Securities."

   From  time to time the  portfolio  of the U.S.  Government  Fund may  consist
primarily of Government National Mortgage Association ("GNMA") certificates,  or
"Ginnie Maes," which are mortgage-backed  securities representing part ownership
of a pool of mortgage loans on which timely payment of interest and principal is
guaranteed  by GNMA  and  backed  by the  full  faith  and  credit  of the  U.S.
Government.  These loans, issued by lenders such as mortgage bankers, commercial
banks and  savings  and loan  associations,  are either  insured by the  Federal
Housing Administration or guaranteed by the Veterans'  Administration.  A "pool"
or group of such  mortgages is assembled  and,  after being approved by GNMA, is
offered to investors  through  securities  dealers.  Once approved by GNMA,  the
timely  payment of interest and principal on each mortgage is guaranteed by GNMA
and  backed by the full  faith and  credit of the U.S.  Government.  Ginnie  Mae
certificates  differ from bonds in that  principal  is paid back  monthly by the
borrower  over  the  term of the  loan  rather  than  returned  in a lump sum at
maturity.  Ginnie Mae certificates are called "pass through"  securities because
both interest and principal payments (including  prepayments) are passed through
to the holder of the certificate.  Upon receipt,  principal  payments  generally
will be used to  purchase  additional  Ginnie  Mae  certificates  or other  U.S.
Government  securities.  Although the Fund invests in  securities  guaranteed by
GNMA and  backed  by the  U.S.  Government,  neither  the  value  of the  Fund's
portfolio nor the value or yield of its shares is so  guaranteed.  The Fund may,
for defensive  purposes,  temporarily  invest part or all of its assets in money
market  instruments,  including deposits and bankers'  acceptances in depository
institutions  insured by the FDIC,  and  short-term  U.S.  Government and agency
securities.

   The potential for appreciation in GNMAs, which might otherwise be expected to
occur as a result of a decline in interest  rates,  may be limited or negated by
increased principal prepayments of the underlying mortgages. Prepayments of GNMA
certificates  occur  with  increasing  frequency  when  mortgage  rates  decline
because,  among  other  reasons,  mortgagors  may be  able  to  refinance  their
outstanding   mortgages  at  lower  interest  rates  or  prepay  their  existing
mortgages.  Such  prepayments  would then be reinvested by the Fund at the lower
current interest rates.

   While mortgages  underlying GNMA certificates have a stated maturity of up to
30 years,  it has been the experience of the mortgage  industry that the average
life of comparable  mortgages,  owing to prepayments,  refinancings and payments
from foreclosures, is considerably less.

   The Fund may invest in other mortgage backed  securities  (MBSs) as discussed
under  "Investment  Methods and Risk Factors" -- "Mortgage Backed Securities and
Collateralized  Mortgage Obligations." MBSs include certain securities issued by
the United States government or one of its agencies or  instrumentalities,  such
as GNMAs, and securities issued by private issuers. The Fund may not invest more
than 20  percent  of the value of its total  assets  in MBSs  issued by  private
issuers.

   The Fund may invest in zero coupon  securities which are debt securities that
pay no cash income but are sold at substantial  discounts from their face value.
Certain  zero coupon  securities  also provide for the  commencement  of regular
interest payments at a deferred date. See "Investment  Methods and Risk Factors"
for a discussion of zero coupon securities.

   The Fund will  attempt  to  maximize  the return on its  portfolio  by taking
advantage of market developments and yield disparities, which may include use of
the following strategies:

   1.  Shortening  the average  maturity of its portfolio in  anticipation  of a
       rise in interest rates so as to minimize depreciation of principal;

   2.  Lengthening  the average  maturity of its portfolio in  anticipation of a
       decline in interest rates so as to maximize appreciation of principal;

   3.  Selling one type of U.S.  Government  obligation  and buying another when
       disparities arise in the relative values of each; and

   4.  Changing from one U.S.  Government  obligation to an essentially  similar
       U.S. Government obligation when their respective yields are distorted due
       to market factors.

   These  strategies  may result in increases or decreases in the Fund's current
income  available for distribution to Fund  stockholders,  and the Fund may hold
obligations  which sell at moderate to  substantial  premiums or discounts  from
face value.

HIGH YIELD FUND

   The  investment  objective  of the High  Yield  Fund is to seek high  current
income.   Capital   appreciation   is  a  secondary   objective.   Under  normal
circumstances,  the  Fund  will  seek  its  investment  objective  by  investing
primarily in a broad range of income producing securities,  including (i) higher
yielding,  higher risk, debt securities  (commonly referred to as "junk bonds");
(ii) preferred stock;  (iii)  securities  issued by foreign  governments,  their
agencies and  instrumentalities,  and foreign  corporations,  provided that such
securities are  denominated in U.S.  dollars;  (iv)  mortgage-backed  securities
("MBSs"); (v) asset-backed  securities;  (vi) securities issued or guaranteed by
the U.S.  Government  or any of its  agencies  or  instrumentalities,  including
Treasury bills, certificates of indebtedness,  notes and bonds; (vii) securities
issued or guaranteed by, the Dominion of Canada or provinces thereof; and (viii)
zero coupon securities.  The Fund may also invest up to 35 percent of its assets
in common stocks  (which may include  ADRs),  warrants and rights.  Under normal
circumstances,  at least 65 percent of the Fund's  total assets will be invested
in high-yielding, high risk debt securities.

   High Yield Fund may invest up to 100 percent of its assets in debt securities
that,  at the time of purchase,  are rated below  investment  grade ("high yield
securities"  or "junk  bonds"),  which  involve  a high  degree  of risk and are
predominantly speculative. A description of debt ratings is included as Appendix
A to this Prospectus. See "Investment Methods and Risk Factors" for a discussion
of the risks  associated  with  investing  in junk  bonds.  Included in the debt
securities  which the High Yield Fund may purchase  are  convertible  bonds,  or
bonds with warrants  attached.  A "convertible  bond" is a bond,  debenture,  or
preferred  share which may be exchanged by the owner for common stock or another
security,  usually  of the same  company,  in  accordance  with the terms of the
issue.  A "warrant"  confers  upon the holder the right to purchase an amount of
securities  at a particular  time and price.  See  "Investment  Methods and Risk
Factors" for a discussion of the risks associated with such securities.
   
   For the year ended  December 31, 1997,  the dollar  weighted  average of High

The foregoing  table is intended solely to provide  disclosure  about High Yield
Fund's  asset  composition  for the year  ended  December  31,  1997.  The asset
composition after this may or may not be approximately the same as shown above.
    
   The Fund may purchase  securities which are obligations of, or guaranteed by,
the  Dominion  of Canada or  provinces  thereof  and debt  securities  issued by
Canadian  corporations.  Canadian securities will not be purchased if subject to
the foreign interest  equalization tax and unless payable in U.S.  dollars.  The
Fund may also invest in debt securities issued by foreign governments (including
Brady Bonds),  their  agencies and  instrumentalities  and foreign  corporations
(including those in emerging markets),  provided such securities are denominated
in U.S. dollars. The Fund's investment in foreign securities, excluding Canadian
securities, will not exceed 25 percent of the Fund's net assets. See "Investment
Methods  and  Risk  Factors"  for a  discussion  of the  risks  associated  with
investing in foreign securities, Brady Bonds and emerging markets.

   The Fund may invest in MBSs, including mortgage  pass-through  securities and
collateralized  mortgage  obligations (CMO's). The Fund may invest in securities
known as "inverse floating obligations," "residual interest bonds," or "interest
only" (IO) or "principal  only" (PO) bonds, the market values of which generally
will be more volatile  than the market  values of most MBSs.  This is due to the
fact that such  instruments  are more  sensitive to interest rate changes and to
the rate of principal  prepayments  than are most other MBSs. The Fund will hold
less than 25 percent of its net assets in MBSs. For a discussion of MBSs and the
risks  associated  with  such  securities,  see  "Investment  Methods  and  Risk
Factors."

   The Fund may also invest in  asset-backed  securities.  These include secured
debt  instruments  backed by automobile  loans,  credit card loans,  home equity
loans, manufactured housing loans and other types of secured loans providing the
source of both  principal and interest  payments.  Asset-backed  securities  are
subject to risks similar

to those  discussed  with  respect to MBSs.  See  "Investment  Methods  and Risk
Factors."

   The Fund may invest in U.S. Government securities. U.S. Government securities
include  bills,  certificates  of  indebtedness,  notes and bonds  issued by the
Treasury or by  agencies  or  instrumentalities  of the U.S.  Government.  For a
discussion of the varying levels of guarantee  associated with particular  types
of U.S. Government Securities, see "Investment Methods and Risk Factors" - "U.S.

   The Fund may invest in zero coupon  securities which are debt securities that
pay no cash income but are sold at substantial  discounts from their face value.
Certain  zero coupon  securities  also provide for the  commencement  of regular
interest payments at a deferred date. See "Investment  Methods and Risk Factors"
for a discussion of zero coupon securities.

   The High Yield Fund may acquire certain  securities that are restricted as to
disposition under federal  securities laws,  including  securities  eligible for
resale to  qualified  institutional  investors  pursuant  to Rule 144A under the
Securities  Act of 1933,  subject  to the  Fund's  policy  that not more than 10
percent of the Fund's  net assets  will be  invested  in  illiquid  assets.  See
"Investment Methods and Risk Factors" for a discussion of restricted securities.

   The High Yield Fund may  purchase  securities  on "when  issued" or  "delayed
delivery"  basis in  excess  of  customary  settlement  periods  for the type of
security  involved.  The Fund may also purchase or sell securities on a "forward
commitment"  basis  and  may  enter  into  "repurchase   agreements,"   "reverse
repurchase  agreements" and "roll transactions." The Fund may lend securities to
broker-dealers,  other  institutions or other persons to earn additional income.
The value of loaned securities may not exceed 33 1/3 percent of the Fund's total
assets. In addition,  the Fund may purchase loans, loan participations and other
types of direct  indebtedness.  See "Investment  Methods and Risk Factors" for a
discussion of the risks associated with these investment practices.

   The Fund may enter into futures  contracts (a type of derivative) (or options
thereon) to hedge all or a portion of its portfolio,  as a hedge against changes
in prevailing levels of interest rates or as an efficient means of adjusting its
exposure  to the bond  market.  The  Fund  will not use  futures  contracts  for
leveraging  purposes.  The Fund will limit its use of futures  contracts so that
initial  margin  deposits  or premiums on such  contracts  used for  non-hedging
purposes  will not equal more than 5 percent of the Funds net asset  value.  The
Fund may  purchase  call and put options  and write such  options on a "covered"
basis.  The Fund may also enter into  interest rate and index swaps and purchase
or sell related  caps,  floors and collars.  The  aggregate  market value of the
Fund's  portfolio  securities  covering  call or put options  will not exceed 25
percent of the Fund's net assets.  See the  discussion of "Options,  Futures and
Forward  Currency  Transactions,"  and "Swaps,  Caps,  Floors and Collars" under
"Investment Methods and Risk Factors."

   From time to time,  the High Yield Fund may invest  part or all of its assets
in U.S. Government securities,  commercial notes or money market instruments. It
is anticipated that the dollar weighted average maturity of the Fund's portfolio
will range from 5 to 15 years under normal circumstances.
   
SECURITY MUNICIPAL BOND FUND

   The investment  objective of Municipal Bond Fund is to obtain as high a level
of interest  income  exempt from regular  federal  income taxes as is consistent
with  preservation  of  stockholders'  capital.  Municipal Bond Fund attempts to
achieve its objective by investing primarily in debt securities, the interest on
which is exempt from federal income taxes. Under normal circumstances,  at least
80 percent of the Fund's net assets will be invested  in  municipal  obligations
the  interest on which is exempt from regular  federal  income tax. A portion of
the Fund's dividends paid in respect of its shares may be subject to the federal
alternative minimum tax.

   The securities in which the Fund invests include debt  obligations  issued by
or on behalf of the states,  territories  and  possessions of the United States,
the  District  of  Columbia,   and  their  political   subdivisions,   agencies,
authorities and instrumentalities, including multi-state agencies or authorities
(and may include certain private activity bonds the interest on which is subject
to the alternative  minimum tax). These securities are referred to as "municipal
securities."

   Municipal bonds are debt  obligations  which generally have a maturity at the
time of issue in excess of one year. They are issued to obtain funds for various
public  purposes,  including  construction of a wide range of public  facilities
such as bridges,  highways,  housing,  hospitals, mass transportation,  schools,
streets,  and water and sewer works.  Other public  purposes for which municipal
bonds may be issued include the refunding of outstanding obligations,  obtaining
funds for general operating expenses and obtaining funds to loan to other public
institutions   and  facilities.   In  addition,   certain  types  of  industrial
development bonds and other private activity bonds are issued by or on behalf of
public  authorities  to obtain funds to provide for  privately-operated  housing
facilities,  and certain facilities for water supply, gas, electricity or sewage
or solid waste disposal.

   The two principal classifications of municipal bonds are "general obligation"
and "revenue" bonds. General obligation bonds are secured by the issuer's pledge
of its full  faith,  credit and taxing  power for the payment of  principal  and
interest.  Revenue  bonds are  payable  only from the  revenues  derived  from a
particular facility or class of facilities, or, in some cases, from the proceeds
of a special

================================================================================
excise or specific  revenue  source.  Revenue  securities  may  include  private
activity bonds.  Such bonds may be issued by or on behalf of public  authorities
to finance various  privately  operated  facilities and are not payable from the
unrestricted  revenues of the issuer. As a result, the credit quality of private
activity bonds is frequently  related directly to the credit standing of private
corporations or other entities.  In addition,  the interest on private  activity
bonds issued after August 7, 1986 is subject to the federal  alternative minimum
tax.  The Fund will not be  restricted  with  respect to the  proportion  of its
assets that may be invested in such obligations.  Accordingly,  the Fund may not
be a suitable  investment  vehicle  for  individuals  or  corporations  that are
subject to the federal alternative minimum tax. Municipal Bond Fund will not
invest  more than 5% of its net assets in  securities  where the  principal  and
interest are the  responsibility of a private  corporation or other entity which
has, including predecessors, less than three years' operational history.

   There are, depending on numerous factors, variations in the risks involved in
holding municipal securities, both within a particular rating classification and
between  classifications.  The market values of outstanding municipal bonds will
vary as a result of the  rating of the issue  and  changing  evaluations  of the
ability of the issuer to meet  interest  and  principal  payments.  Such  market
values will also change in response to changes in the interest  rates payable on
new issues of municipal  bonds.  Should such interest  rates rise, the values of
outstanding  bonds,  including  those held in Municipal  Bond Fund's  portfolio,
would decline;  should such interest  rates  decline,  the values of outstanding
bonds would increase.

   As a result of litigation or other  factors,  the power or ability of issuers
of municipal  securities to pay  principal  and/or  interest  might be adversely
affected.  Municipal  securities  are subject to the  provisions of  bankruptcy,
insolvency and other laws  affecting the rights and remedies of creditors,  such
as the  Federal  Bankruptcy  Code,  and laws,  if any,  which may be  enacted by
Congress or state  legislatures  extending  the time for payment of principal or
interest  or both,  or  imposing  other  constraints  upon  enforcement  of such
obligations or upon the power of municipalities to levy taxes.

   Municipal  Bond Fund may invest without  percentage  limitations in issues of
municipal securities which have similar characteristics, such as the location of
their  issuers  in the same  geographic  region or the  derivation  of  interest
payments  from  revenues on similar  projects  (for  example,  electric  utility
systems,  hospitals, or housing finance agencies). Thus, Municipal Bond Fund may
invest more than 25% of its total assets in securities issued in a single state.
However,  it may not invest more than 25% of its total  assets in one  industry.
Consequently,   the  Fund's  portfolio  of  municipal  securities  may  be  more
susceptible  to  the  risks  of  adverse  economic,   political,  or  regulatory
developments  than would be the case with a portfolio of securities  required to
be more diversified as to geographic region and/or source of revenue.

   The Fund's  investments in municipal  securities are limited to securities of
"investment  grade" quality,  that is,  securities rated within the four highest
rating  categories of Moody's (Aaa,  Aa, A, Baa), S&P (AAA, AA, A, BBB) or Fitch
(AAA,  AA,  A,  BBB),  except  that  the  Fund may  purchase  unrated  municipal
securities  (i) where the securities are guaranteed as to principal and interest
by the full faith and credit of the U.S. Government or are short-term  municipal
securities  (those  having a maturity  of less than one year) of issuers  having
outstanding  at the time of purchase an issue of  municipal  bonds having one of
the four  highest  ratings,  or (ii) where,  in the opinion of the  Sub-Adviser,
Salomon  Brothers  Asset  Management  Inc.  ("Salomon  Brothers"),  the  unrated
municipal  securities are comparable in quality to those within the four highest
ratings.  However,  Municipal  Bond Fund will not purchase an unrated  municipal
security (other than a security described in (i) above) if, after such purchase,
more than 20  percent of the  Fund's  total  assets  would be  invested  in such
unrated municipal securities.

   With respect to rated  securities,  there is no percentage  limitation on the
amount of the Fund's  assets  which may be  invested  in  securities  within any
particular rating  classification,  but the Fund anticipates that it will invest
no more than 25 percent of its total assets in  securities  rated Baa by Moody's
or BBB by Standard & Poor's or Fitch.  A description of the ratings is contained
in  Appendix  B  to  this   Prospectus.   Such   securities   have   speculative
characteristics as discussed under "Investment Methods and Risk Factors."

   If the Fund holds a security  whose  rating  drops below Baa or BBB,  Salomon
Brothers will  reevaluate  the credit risk presented by the security in light of
current  market  conditions  and determine  whether to retain or dispose of such
security.  The Fund  will not  retain  securities  rated  below Baa or BBB in an
amount that exceeds 5 percent of its net assets.

   Municipal  Bond Fund invests  primarily in  municipal  bonds with  maturities
greater than one year. It is expected that the Fund's average portfolio maturity
under normal  circumstances will be in the 15- to 25-year range.  Municipal Bond
Fund also will invest for various  purposes in short-term  (maturity equal to or
less  than  one  year)  securities  which,  to the  extent  practicable  will be
short-term  municipal  securities.  Short-term  investments may be made, pending
investment of funds in municipal bonds, in order to maintain liquidity,  to meet
redemption requests, or to maintain a temporary "defensive"  investment position
when,  in the opinion of the  Investment  Manager,  it is  advisable to do so on
account of current or anticipated market conditions.  Except when in a temporary
defensive position, investments

SECURITY FUNDS
PROSPECTUS
================================================================================
in short-term  municipal  securities  will represent less than 20 percent of the
Fund's total assets.

   From time to time, on a temporary  basis,  Municipal  Bond Fund may invest in
fixed income obligations on which the interest is subject to federal income tax.
Except when the Fund is in a temporary "defensive"  investment position, it will
not  purchase a taxable  security  if, as a result,  more than 20 percent of its
total  assets  would be invested in taxable  securities.  This  limitation  is a
fundamental  policy of  Municipal  Bond Fund,  and may not be changed  without a
majority vote of the Fund's outstanding shares. Temporary taxable investments of
the Fund may consist of obligations issued or guaranteed by the U.S.  Government
or its agencies or instrumentalities, commercial paper rated A-1 by S&P, Prime-1
by  Moody's  or F-1 by Fitch,  corporate  obligations  rated AAA or AA by S&P or
Fitch or Aaa or Aa by Moody's,  certificates of deposit or bankers'  acceptances
of domestic  banks or thrifts with at least $2 billion in assets,  or repurchase
agreements with such banks or with broker-dealers.

   The Fund may invest in zero coupon  securities which are debt securities that
pay no cash income but are sold at substantial  discounts from their face value.
Certain  zero coupon  securities  also provide for the  commencement  of regular
interest payments at a deferred date. See "Investment  Methods and Risk Factors"
for a discussion of zero coupon securities.

   From time to time, Municipal Bond Fund may purchase municipal securities on a
when-issued or delayed  delivery  basis.  The Fund does not believe that its net
asset value or income will be  adversely  affected by its  purchase of municipal
securities on a when-issued or delayed delivery basis.  For further  information
regarding when-issued  purchases,  see "Investment Methods and Risk Factors" and
the Funds' Statement of Additional Information.

   Municipal Bond Fund may also purchase from banks or broker/dealers, municipal
securities  together with the right to resell the securities to the seller at an
agreed-upon  price or yield within a specified period prior to the maturity date
of the  securities.  Such a right to resell is commonly  known as a "put" and is
also referred to as a "stand-by commitment" on the part of the seller. The price
which Municipal Bond Fund pays for the municipal  securities with puts generally
is  higher  than the  price  which  otherwise  would  be paid for the  municipal
securities  alone. The Fund uses puts for liquidity  purposes in order to permit
it to remain more fully invested in municipal securities than would otherwise be
the case by providing a ready  market for certain  municipal  securities  in its
portfolio at an acceptable  price.  The put generally is for a shorter term than
the  maturity of the  municipal  security  and does not  restrict in any way the
Fund's  ability to dispose of (or retain) the  municipal  security.  In order to
ensure that the interest on municipal  securities  subject to puts is tax-exempt
to the  Fund,  it  will  limit  its  use of  puts  in  accordance  with  current
interpretations  or  rulings  of the  Internal  Revenue  Service.  Because it is
difficult to evaluate the  likelihood of exercise or the potential  benefit of a
put, puts will be  determined  to have a "value" of zero,  regardless of whether
any direct or indirect  consideration  was paid. There is a risk that the seller
of the put may not be able to  repurchase  the security upon exercise of the put
by  Tax-Exempt  Fund.  For  further  information  regarding  puts  and  stand-by
commitments, see the Funds' Statement of Additional Information.

   The  Municipal  Bond Fund may purchase or sell  futures  contracts (a type of
derivative) on (a) debt  securities that are backed by the full faith and credit
of the U.S. Government, such as long-term U.S. Treasury Bonds and Treasury Notes
and (b) municipal bond indices.  The Fund may use futures contracts to hedge all
or a portion of its portfolio,  as a hedge against changes in prevailing  levels
of interest rates or as an efficient means of adjusting its exposure to the bond
market.  The Fund  will  not use  futures  contracts  for  leveraging  purposes.
Currently  at  least  one  exchange  trades  futures  contracts  on an  index of
long-term  municipal  bonds,  and the Fund reserves to right to conduct  futures
transactions based on an index which may be developed in the future to correlate
with price movements in municipal  obligations.  It is not presently anticipated
that any of these  strategies will be used to a significant  degree by the Fund.
For further information regarding futures contracts, see "Investment Methods and
Risk Factors" and the Fund's Statement of Additional Infomration.
    
SECURITY CASH FUND

   The  investment  objective of Cash Fund is to seek as high a level of current
income as is consistent with  preservation  of capital and liquidity.  Cash Fund
will  attempt to achieve its  objective  by investing at least 95 percent of its
total assets, measured at the time of investment,  in a diversified portfolio of
highest  quality  money  market  instruments.  Cash Fund may also invest up to 5
percent of its total assets, measured at the time of investment, in money market
instruments that are in the  second-highest  rating category for short-term debt
obligations.  Money market  instruments  in which the Fund may invest consist of
the following:

   U.S.  Government  Securities  --  Obligations  issued  or  guaranteed  (as to
principal or interest) by the United States  Government or its agencies (such as
the Small Business  Administration and Government National Mortgage Association)
or  instrumentalities  (such as Federal  Home Loan Banks and Federal Land Banks)
and instruments fully collateralized with such obligations.

   Bank  Obligations --  Obligations  of banks or savings and loan  associations
that are members of the Federal  Deposit  Insurance  Corporation and instruments
fully collateralized with such obligations.

SECURITY FUNDS
PROSPECTUS
================================================================================
   Corporate  Obligations -- Commercial  paper issued by corporations  and rated
Prime-1 or Prime-2 by  Moody's  or A-1 or A-2 by S&P,  or other  corporate  debt
instruments  rated Aaa or Aa or better by Moody's or AAA or AA or better by S&P,
subject to the  limitations on investment in  instruments in the  second-highest
rating category, discussed below.

   Cash Fund may invest only in U.S. dollar denominated money market instruments
that present  minimal  credit risk and,  with respect to 95 percent of its total
assets, measured at the time of investment, that are of the highest quality. The
Investment  Manager will determine  whether a security  presents  minimal credit
risk under procedures adopted by Cash Fund's Board of Directors. A security will
be considered to be highest quality (1) if rated in the highest category, (e.g.,
Aaa or  Prime-1  by  Moody's  or AAA or A-1 by S&P)  by (i)  any two  nationally
recognized statistical rating organizations ("NRSROs") or, (ii) if rated by only
one NRSRO,  by that NRSRO;  (2) if issued by an issuer that has short-term  debt
obligations of comparable maturity, priority, and security and that are rated in
the highest rating  category by (i) any two NRSROs or, (ii) if rated by only one
NRSRO, by that NRSRO; or (3) an unrated  security that is of comparable  quality
to a security in the highest  rating  category as determined  by the  Investment
Manager and whose acquisition is approved or ratified by the Board of Directors.
With  respect  to 5  percent  of its  total  assets,  measured  at the  time  of
investment,  Cash Fund may also invest in money market  instruments  that are in
the second-highest  rating category for short-term debt obligations (e.g., rated
Aa or Prime 2 by Moody's or AA or A-2 by S&P). A money market instrument will be
considered  to be in the  second-highest  rating  category  under  the  criteria
described  above with respect to  investments  considered  highest  quality,  as
applied to instruments in the second-highest rating category.  See Appendix A to
this  Prospectus  for a  description  of the principal  types of securities  and
instruments in which Cash Fund will invest as well as a description of the above
mentioned ratings.

   Cash Fund may not invest more than 5 percent of its total assets, measured at
the time of  investment,  in the  securities  of any one issuer  that are of the
highest  quality or more than the  greater  of 1 percent of its total  assets or
$1,000,000,  measured at the time of investment, in securities of any one issuer
that are in the  second-highest  rating category,  except that these limitations
shall not apply to U.S. Government securities. The Fund may exceed the 5 percent
limitation for up to three business days after the purchase of the securities of
any one  issuer  that are of the  highest  quality,  provided  that the Fund has
outstanding at any time not more than one such investment.  In the event that an
instrument  acquired by Cash Fund  ceases to be of the quality  that is eligible
for the Fund,  the Fund shall  promptly  dispose of the instrument in an orderly
manner  unless the Board of Directors  determines  that this would not be in the
best interests of the Fund.

   Cash Fund will invest in money market  instruments of varying maturities (but
no longer than thirteen  months) in an effort to earn as high a level of current
income as is consistent with  preservation  of capital and liquidity.  Cash Fund
intends to maintain a  dollar-weighted  average maturity in its portfolio of not
more than 90 days.  The Fund seeks to maintain a stable net asset value of $1.00
per share, although there can be no assurance that it will be able to do so.

   Cash Fund may acquire  one or more of the types of  securities  listed  above
subject to  repurchase  agreement.  Not more than 10 percent of the Fund's total
assets may be invested in illiquid assets,  which include repurchase  agreements
with maturities of over seven days.  Cash Fund may invest in instruments  having
rates of interest that are adjusted periodically according to a specified market
rate for such investments ("Variable Rate Instruments").  The interest rate on a
Variable  Rate  Instrument  is  ordinarily  determined  by reference to, or is a
percentage  of, an objective  standard such as a bank's prime rate or the 91-day
U.S. Treasury Bill rate. Generally, the changes in the interest rate on Variable
Rate Instruments  reduce the fluctuation in the market value of such securities.
Accordingly,  as interest rates decrease or increase,  the potential for capital
appreciation or depreciation is less than for fixed-rate obligations.  Cash Fund
determines  the maturity of Variable Rate  Instruments  in accordance  with Rule
2a-7 under the Investment  Company Act of 1940 which allows the Fund to consider
the maturity date of such  instruments to be the period remaining until the next
readjustment  of the interest  rate rather than the maturity date on the face of
the instrument.

   Cash  Fund  may  acquire  certain   securities  that  are  restricted  as  to
disposition under the federal securities laws, provided that such securities are
eligible for resale to qualified  institutional  investors pursuant to Rule 144A
under the Securities Act of 1933, and subject to the Fund's policy that not more
than 10 percent of the Fund's total assets will be invested in illiquid  assets.
See  "Investment  Methods  and  Risk  Factors"  for a  discussion  of Rule  144A
Securities.

INVESTMENT METHODS AND RISK FACTORS

   Some of the risk  factors  related to  certain  securities,  instruments  and
techniques  that may be used by one or more of the  Funds are  described  in the
"Investment  Objective  and  Policies"  section  of this  Prospectus  and in the
"Investment   Objectives  and  Policies"  and  "Investment  Policy  Limitations"
sections of the Funds' Statement of Additional  Information.  The following is a
description of certain  additional risk factors  related to various  securities,
instruments  and  techniques.  The risks so described  only apply to those Funds
which may invest in such securities

and instruments or use such techniques.  Also included is a general  description
of some of the investment instruments,  techniques and methods which may be used
by one or more of the Funds.  The  methods  described  only apply to those Funds
which may use such methods.
   
INVESTMENT VEHICLES

   BAA OR BBB SECURITIES -- Certain of the Funds may invest in medium grade debt
securities  (debt securities rated Baa by Moody's or BBB by S&P and Fitch at the
time of purchase,  or if unrated,  of  equivalent  quality as  determined by the
Investment  Manager).  Baa  securities  are  considered  to  be  "medium  grade"
obligations  by  Moody's  and BBB is the  lowest  classification  which is still
considered an  "investment  grade"  rating by S&P and Fitch.  Bonds rated Baa by
Moody's or BBB by S&P and Fitch have speculative characteristics and may be more
susceptible  than higher  grade bonds to adverse  economic  conditions  or other
adverse  circumstances which may result in a weakened capacity to make principal
and interest  payments.  Corporate  Bond,  Limited  Maturity Bond and High Yield
Funds may invest in higher yield debt  securities  in the lower  rating  (higher
risk)  categories of the recognized  rating  services  (commonly  referred to as
"junk bonds").  See Appendix A to this Prospectus for a complete  description of
corporate  bond  ratings  and  see  "Risks   Associated  with  Lower-Rated  Debt
Securities (Junk Bonds)."
    
   U.S. GOVERNMENT SECURITIES -- Each of the Funds may invest in U.S. Government
securities which include  obligations  issued or guaranteed (as to principal and
interest) by the United  States  Government  or its agencies  (such as the Small
Business  Administration,  the Federal  Housing  Administration,  and Government
National Mortgage Association),  or instrumentalities (such as Federal Home Loan
Banks and Federal Land Banks),  and instruments fully  collateralized  with such
obligations such as repurchase agreements. Some U.S. Government securities, such
as Treasury  bills and bonds,  are supported by the full faith and credit of the
U.S.  Treasury;  others are  supported by the right of the issuer to borrow from
the  Treasury;   others,   such  as  those  of  the  Federal  National  Mortgage
Association, are supported by the discretionary authority of the U.S. Government
to purchase the agency's obligations; still others, such as those of the Student
Loan   Marketing   Association,   are  supported  only  by  the  credit  of  the
instrumentality.  Government  National Mortgage  Association (GNMA) certificates
are mortgage-backed securities representing part ownership of a pool of mortgage
loans on which timely  payment of interest and  principal is  guaranteed  by the
full  faith  and  credit  of  the  U.S.  Government.  Although  U.S.  Government
securities   are   guaranteed   by  the  U.S.   Government,   its   agencies  or
instrumentalities, shares of the Funds are not so guaranteed in any way.

   CONVERTIBLE  SECURITIES  AND  WARRANTS  -- Certain of the Funds may invest in
debt or preferred equity securities  convertible into or exchangeable for equity
securities.  Traditionally,   convertible  securities  have  paid  dividends  or
interest  at rates  higher  than  common  stocks but lower than  non-convertible
securities.  They generally  participate in the  appreciation or depreciation of
the underlying stock into which they are convertible, but to a lesser degree. In
recent years,  convertibles  have been  developed  which combine higher or lower
current  income with options and other  features.  Warrants are options to buy a
stated number of shares of common stock at a specified price any time during the
life of the warrants (generally two or more years).

   MORTGAGE BACKED SECURITIES AND COLLATERALIZED MORTGAGE OBLIGATIONS -- Certain
of the Funds may invest in mortgage-backed securities (MBSs), including mortgage
pass through securities and collateralized  mortgage  obligations  (CMOs).  MBSs
include certain  securities issued or guaranteed by the United States government
or one of its agencies or  instrumentalities,  such as the  Government  National
Mortgage  Association (GNMA),  Federal National Mortgage  Association (FNMA), or
Federal Home Loan Mortgage  Corporation  (FHLMC);  securities  issued by private
issuers that represent an interest in or are  collateralized by  mortgage-backed
securities issued or guaranteed by the U.S. government or one of its agencies or
instrumentalities;  and securities  issued by private  issuers that represent an
interest in or are  collateralized  by mortgage  loans.  A mortgage pass through
security  is a pro rata  interest  in a pool of  mortgages  where  the cash flow
generated from the mortgage collateral is passed through to the security holder.
CMOs are  obligations  fully  collateralized  by a  portfolio  of  mortgages  or
mortgage-related securities. Certain of the Funds may invest in securities known
as "inverse  floating  obligations,"  "residual  interest  bonds," and "interest
only" (IO) and  "principal  only" (PO)  bonds,  the market  values of which will
generally  be more  volatile  than the market  values of most  MBSs.  An inverse
floating obligation is a derivative adjustable rate security with interest rates
that adjust or vary  inversely  to changes in market  interest  rates.  The term
"residual  interest"  bond is used  generally to describe  those  instruments in
collateral  pools, such as CMOs, which receive any excess cash flow generated by
the pool once all other bondholders and expenses have been paid. IOs and POs are
created by separating the interest and principal payments generated by a pool of
mortgage-backed bonds to create two classes of securities.  Generally, one class
receives  interest  only  payments  (IOs) and the  other  class  principal  only
payments  (POs).  MBSs  have  been  referred  to as  "derivatives"  because  the
performance of MBSs is dependent upon and derived from underlying securities.

   Investment  in MBSs poses several  risks,  including  prepayment,  market and
credit  risks.  PREPAYMENT  RISK  reflects the chance that  borrowers may prepay
their

                                       13

SECURITY FUNDS
PROSPECTUS
================================================================================
mortgages faster than expected,  thereby affecting the investment's average life
and perhaps its yield.  Borrowers are most likely to exercise  their  prepayment
options  at a  time  when  it is  least  advantageous  to  investors,  generally
prepaying  mortgages as interest  rates fall,  and slowing  payments as interest
rates rise.  Certain  classes of CMOs may have priority over others with respect
to the receipt of  prepayments  on the mortgages and the Fund may invest in CMOs
which are subject to greater risk of prepayment. MARKET RISK reflects the chance
that the price of the security may fluctuate over time. The price of MBSs may be
particularly  sensitive to  prevailing  interest  rates,  the length of time the
security is expected to be  outstanding  and the  liquidity  of the issue.  In a
period of unstable  interest  rates,  there may be decreased  demand for certain
types of MBSs, and a fund invested in such  securities  wishing to sell them may
find it difficult to find a buyer, which may in turn decrease the price at which
they may be sold.  CREDIT RISK reflects the chance that the Fund may not receive
all or part of its principal because the issuer or credit enhancer has defaulted
on its obligations.  Obligations issued by U.S.  Government-related entities are
guaranteed  by  the  agency  or   instrumentality,   and  some,   such  as  GNMA
certificates,  are supported by the full faith and credit of the U.S.  Treasury;
others are  supported  by the right of the issuer to borrow  from the  Treasury;
others, such as those of the FNMA, are supported by the discretionary  authority
of the U.S. Government to purchase the agency's  obligations;  still others, are
supported only by the credit of the instrumentality.  Although securities issued
by U.S.  Government-related  agencies are guaranteed by the U.S. Government, its
agencies or  instrumentalities,  shares of the Fund are not so guaranteed in any
way. The performance of private label MBSs, issued by private  institutions,  is
based on the financial health of those institutions.

   ASSET-BACKED   SECURITIES  --  Certain  of  the  Funds  may  also  invest  in
"asset-backed  securities."  These include  secured debt  instruments  backed by
automobile  loans,  credit card loans, home equity loans,  manufactured  housing
loans and other types of secured loans  providing  the source of both  principal
and  interest.  Asset-backed  securities  are subject to risks  similar to those
discussed above with respect to MBSs.

   WHEN-ISSUED  AND FORWARD  COMMITMENT  SECURITIES  -- Certain of the Funds may
purchase securities on a "when-issued" basis and may purchase or sell securities
on a "forward commitment" basis in order to hedge against anticipated changes in
interest  rates and prices.  The price,  which is  generally  expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities  take place at a later date.  When-issued  securities and forward
commitments  may be sold prior to the settlement  date, but the Funds will enter
into  when-issued  and forward  commitments  only with the intention of actually
receiving or delivering the securities, as the case may be. No income accrues on
securities  which have been purchased  pursuant to a forward  commitment or on a
when-issued basis prior to delivery of the securities. If a Fund disposes of the
right to acquire a when-issued  security prior to its acquisition or disposes of
its right to  deliver or receive  against a forward  commitment,  it may incur a
gain or loss. At the time a Fund enters into a transaction  on a when-issued  or
forward  commitment  basis,  a segregated  account  consisting of cash or liquid
securities  equal  to  the  value  of  the  when-issued  or  forward  commitment
securities  will be established  and  maintained  with its custodian and will be
marked to market daily. There is a risk that the securities may not be delivered
and that the Fund may incur a loss.

   RESTRICTED  SECURITIES  (RULE  144A  SECURITIES)  -- Certain of the Funds may
invest in restricted  securities  which are securities that are restricted as to
disposition under the federal securities laws, provided that such securities are
eligible for resale to qualified  institutional  investors pursuant to Rule 144A
under the Securities Act of 1933.

   The High Yield Fund may purchase restricted securities,  including securities
that are not  eligible  for resale  pursuant to Rule 144A.  The Fund may acquire
such securities through private placement transactions, directly from the issuer
or from security holders,  generally at higher yields or on terms more favorable
to  investors  than  comparable   publicly  traded  securities.   However,   the
restrictions  on resale of such securities may make it difficult for the Fund to
dispose of such securities at the time considered most advantageous,  and/or may
involve  expenses that would not be incurred in the sale of securities that were
freely  marketable.  Risks  associated  with restricted  securities  include the
potential obligation to pay all or part of the registration expenses in order to
sell certain  restricted  securities.  A considerable  period of time may elapse
between the time of the decision to sell a security and the time the Fund may be
permitted to sell it under an effective  registration  statement.  If,  during a
period,  adverse  conditions  were to  develop,  the  Fund  might  obtain a less
favorable price than prevailing when it decided to sell.

   The Fund's Board of Directors is responsible for developing and  establishing
guidelines and procedures for determining the liquidity of Rule 144A securities.
As  permitted  by  Rule  144A,   the  Board  of  Directors  has  delegated  this
responsibility to the Investment Manager. In making the determination  regarding
the  liquidity of Rule 144A  securities,  the  Investment  Manager will consider
trading markets for the specific  security taking into account the  unregistered
nature  of a Rule  144A  security.  In  addition,  the  Investment  Manager  may
consider:  (1) the frequency of trades and quotes; (2) the number of dealers and
potential  purchasers;  (3) dealer  undertakings  to make a market;  and (4) the
nature of the security and of the market place trades (e.g.,  the time needed to

of  soliciting  offers and the  mechanics of  transfer).  Investing in Rule 144A
securities  could have the effect of  increasing  the amount of a Fund's  assets
invested  in illiquid  securities  to the extent  that  qualified  institutional
buyers become uninterested, for a time, in purchasing these securities.

   SOVEREIGN DEBT.  Certain of the Funds may invest in sovereign debt securities
of  emerging  market  governments,  including  Brady  Bonds,  provided  they are
denominated  in U.S.  dollars.  Sovereign  debt  securities  are those issued by
emerging  market  governments  that  are  traded  in the  markets  of  developed
countries  or groups of  developed  countries.  Investments  in such  securities
involve special risks.  The issuer of the debt or the  governmental  authorities
that  control  the  repayment  of the debt may be unable or  unwilling  to repay
principal  or  interest  when due in  accordance  with the  terms of such  debt.
Periods of economic uncertainty may result in the volatility of market prices of
sovereign debt, and in turn the Fund's net asset value, to a greater extent than
the  volatility  inherent  in  domestic  fixed  income  securities.  A sovereign
debtor's  willingness or ability to repay principal and pay interest in a timely
manner may be affected by, among other  factors,  its cash flow  situation,  the
extent of its foreign reserves,  the availability of sufficient foreign exchange
on the date a payment is due,  the relative  size of the debt service  burden to
the  economy  as  a  whole,  the  sovereign  debtor's  policy  toward  principal
international  lenders and the political constraints to which a sovereign debtor
may be subject.  Emerging  market  governments  could default on their sovereign
debt.  Such  sovereign  debtors also may be dependent on expected  disbursements
from foreign  governments,  multilateral  agencies and other entities  abroad to
reduce  principal and interest  arrearages on their debt.  The commitment on the
part of these governments, agencies and others to make such disbursements may be
conditioned on a sovereign  debtor's  implementation  of economic reforms and/or
economic  performance  and the  timely  service  of such  debtor's  obligations.
Failure to implement such reforms,  achieve such levels of economic  performance
or repay principal or interest when due, may result in the  cancellation of such
third  parties'  commitments  to lend funds to the sovereign  debtor,  which may
further impair such debtor's ability or willingness to timely service its debt.

   The occurrence of political,  social or diplomatic  changes in one or more of
the  countries   issuing  sovereign  debt  could  adversely  affect  the  Fund's
investments.  Emerging  markets are faced with social and  political  issues and
some of them have  experienced  high rates of inflation in recent years and have
extensive  internal debt. Among other effects,  high inflation and internal debt
service  requirements  may adversely  affect the cost and availability of future
domestic  sovereign  borrowing to finance  governmental  programs,  and may have
other adverse social, political and economic consequences.  Political changes or
a deterioration  of a country's  domestic economy or balance of trade may affect
the  willingness  of countries to service  their  sovereign  debt.  Although the
Investment  Manager  intends to manage the Funds in a manner that will  minimize
the  exposure to such risks,  there can be no assurance  that adverse  political
changes  will not cause a Fund to suffer a loss of interest or  principal on any
of its holdings.

   In recent  years,  some of the emerging  market  countries  have  encountered
difficulties  in  servicing  their  sovereign  debt  obligations.  Some of these
countries have withheld payments of interest and/or principal of sovereign debt.
These  difficulties  have also led to  agreements to  restructure  external debt
obligations -- in particular,  commercial bank loans,  typically by rescheduling
principal payments, reducing interest rates and extending new credits to finance
interest  payments on existing debt. In the future,  holders of emerging  market
sovereign   debt   securities   may  be  requested  to  participate  in  similar
rescheduling  of such debt.  Certain  emerging  market  countries  are among the
largest debtors to commercial  banks and foreign  governments.  At times certain
emerging market countries have declared a moratorium on the payment of principal
and  interest on external  debt;  such a  moratorium  is  currently in effect in
certain emerging market countries.  There is no bankruptcy proceeding by which a
creditor  may  collect in whole or in part  sovereign  debt on which an emerging
market government has defaulted.

   The ability of emerging  market  governments to make timely payments on their
sovereign  debt  securities is likely to be  influenced  strongly by a country's
balance  of trade and its  access to trade and other  international  credits.  A
country whose exports are concentrated in a few commodities  could be vulnerable
to a decline  in the  international  prices of one or more of such  commodities.
Increased  protectionism on the part of a country's  trading partners could also
adversely  affect its  exports.  Such events  could  diminish a country's  trade
account  surplus,  if any. To the extent that a country receives payment for its
exports in  currencies  other  than hard  currencies,  its  ability to make hard
currency payments could be affected.

   Investors  should also be aware that certain  sovereign  debt  instruments in
which a Fund may invest  involve  great risk.  As noted  above,  sovereign  debt
obligations issued by emerging market governments generally are deemed to be the
equivalent in terms of quality to  securities  rated below  investment  grade by
Moody's and S&P. Such securities are regarded as predominantly  speculative with
respect  to the  issuer's  capacity  to pay  interest  and  repay  principal  in
accordance  with the terms of the obligations and involve major risk exposure to
adverse  conditions.  Some of such securities,  with respect to which the issuer
currently  may not be  paying  interest  or may be in  payment  default,  may be
comparable  to  securities  rated D by S&P or C by  Moody's.  The  Fund may have
difficulty disposing of and valuing

SECURITY FUNDS
PROSPECTUS
================================================================================
certain sovereign debt obligations because there may be a limited trading market
for such  securities.  Because there is no liquid  secondary  market for many of
these  securities,  the Fund anticipates that such securities could be sold only
to a limited number of dealers or  institutional  investors.  Certain  sovereign
debt securities may be illiquid.

   BRADY BONDS. Certain of the Funds may invest in "Brady Bonds," which are debt
restructurings  that provide for the exchange of cash and loans for newly issued
bonds.  Brady Bonds are  securities  created  through  the  exchange of existing
commercial bank loans to public and private entities in certain emerging markets
for new bonds in connection with debt  restructuring  under a debt restructuring
plan  introduced by former U.S.  Secretary of the  Treasury,  Nicholas F. Brady.
Brady Bonds recently have been issued by the  governments of Argentina,  Brazil,
Bulgaria,   Costa  Rica,  Dominican  Republic,   Jordan,  Mexico,  Nigeria,  The
Philippines,  Uruguay,  Venezuela,  Ecuador  and Poland and are  expected  to be
issued  by other  emerging  market  countries.  Approximately  $150  billion  in
principal  amount of Brady Bonds has been issued to date. Fund investors  should
recognize that Brady Bonds have been issued only recently and,  accordingly,  do
not  have  a  long  payment  history.  Brady  Bonds  may  be  collateralized  or
uncollateralized,  are issued in various currencies  (primarily the U.S. dollar)
and are actively  traded in the secondary  market for Latin  American  debt. The
Salomon  Brothers  Brady Bond Index  provides  a  benchmark  that can be used to
compare  returns of  emerging  market  Brady  Bonds  with  returns in other bond
markets, e.g., the U.S. bond market.

   The  High  Yield  Fund  may  invest  only  in  collateralized   Brady  Bonds,
denominated  in U.S.  dollars.  U.S.  dollar-denominated,  collateralized  Brady
Bonds,  which may be fixed rate par bonds or floating rate discount  bonds,  are
collateralized in full as to principal by U.S. Treasury zero coupon bonds having
the same maturity as the bonds.  Interest  payments on such bonds  generally are
collateralized  by cash or  securities  in an amount that,  in the case of fixed
rate bonds,  is equal to at least one year of rolling  interest  payments or, in
the case of  floating  rate  bonds,  initially  is equal to at least one  year's
rolling interest payments based on the applicable  interest rate at the time and
is adjusted at regular intervals thereafter.

   LOAN PARTICIPATIONS AND ASSIGNMENTS.  The High Yield Fund may invest in fixed
and floating rate loans ("Loans") arranged through private  negotiations between
a  corporate  or  foreign  entity  and  one  or  more   financial   institutions
("Lenders").  Certain of the Fund's investments in Loans in emerging markets are
expected to be in the form of  participations  in Loans  ("Participations")  and
assignments   of   portions  of  Loans  from  third   parties   ("Assignments").
Participations   typically   will  result  in  the  Fund  having  a  contractual
relationship only with the Lender, not with the borrower. The Fund will have the
right to receive  payments of  principal,  interest  and any fees to which it is
entitled only from the Lender selling the Participation and only upon receipt by
the Lender of the payments from the  borrower.  In  connection  with  purchasing
Participations,  the Fund generally will have no right to enforce  compliance by
the borrower  with the terms of the loan  agreement  relating to the Loan ("Loan
Agreement"),  nor any rights of set-off  against the borrower,  and the Fund may
not directly  benefit from any  collateral  supporting  the Loan in which it has
purchased the  Participation.  As a result, the Fund will assume the credit risk
of both the borrower and the Lender that is selling the Participation.

   In the event of the  insolvency of the Lender  selling a  Participation,  the
Fund may be treated as a general creditor of the Lender and may not benefit from
any  set-off  between  the  Lender  and the  borrower.  The  Fund  will  acquire
Participations  only if the  Lender  interpositioned  between  the  Fund and the
borrower is determined by the Investment  Manager to be  creditworthy.  When the
Fund  purchases  Assignments  from Lenders,  the Fund will acquire direct rights
against the  borrower  on the Loan.  However,  since  Assignments  are  arranged
through private  negotiations  between  potential  assignees and assignors,  the
rights and  obligations  acquired by the Fund as the  purchaser of an Assignment
may differ from, and be more limited than, those held by the assigning Lender.

   The Fund may have difficulty disposing of Assignments and Participations. The
liquidity  of such  securities  is limited  and the Fund  anticipates  that such
securities  could be sold only to a limited number of  institutional  investors.
The lack of a liquid  secondary market could have an adverse impact on the value
of  such  securities  and  on  the  Fund's  ability  to  dispose  of  particular
Assignments or Participations  when necessary to meet the Fund's liquidity needs
or in response to a specific  economic  event,  such as a  deterioration  in the
creditworthiness  of the  borrower.  The lack of a liquid  secondary  market for
Assignments and  Participations  also may make it more difficult for the fund to
assign a value to those  securities for purposes of valuing the Fund's portfolio
and calculating its net asset value.

   ZERO  COUPON  SECURITIES  -- Certain of the Funds may invest in certain  zero
coupon  securities that are "stripped" U.S.  Treasury notes and bonds. The Funds
also may  invest in zero  coupon and other deep  discount  securities  issued by
foreign  governments and domestic and foreign  corporations,  including  certain
Brady Bonds and other foreign debt and payment-in-kind  securities.  Zero coupon
securities  pay no interest to holders  prior to maturity,  and  payment-in-kind
securities pay interest in the form of additional securities. However, a portion
of the original issue  discount on zero coupon  securities and the "interest" on
payment-in-kind  securities  will be included in the  investing  Fund's  income.
Accordingly, for the Fund to qualify for tax treatment as a regulated investment
company and to avoid certain taxes

SECURITY FUNDS
PROSPECTUS
================================================================================
(see  "Taxes"  in the  Statement  of  Additional  Information),  the Fund may be
required to  distribute  an amount that is greater than the total amount of cash
it  actually  receives.  These  distributions  must be made from the Fund's cash
assets or, if necessary, from the proceeds of sales of portfolio securities. The
Fund will not be able to purchase  additional  income-producing  securities with
cash used to make such  distributions  and its current income  ultimately may be
reduced as a result. Zero coupon and payment-in-kind securities usually trade at
a deep  discount  from  their  face or par value and will be  subject to greater
fluctuations  of market value in response to changing  interest  rates than debt
obligations of comparable maturities that make current distributions of interest
in cash.

   REPURCHASE AGREEMENTS, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS --
Each of the Funds may enter into repurchase  agreements.  Repurchase  agreements
are  transactions  in which the  purchaser  buys a debt  security from a bank or
recognized securities dealer and simultaneously  commits to resell that security
to the bank or dealer at an agreed upon price,  date and market rate of interest
unrelated to the coupon rate or maturity of the purchased  security.  Repurchase
agreements  are  considered  to be  loans  which  must be  fully  collateralized
including  interest  earned thereon during the entire term of the agreement.  If
the  institution  defaults  on the  repurchase  agreement,  the Fund will retain
possession of the underlying securities. If bankruptcy proceedings are commenced
with respect to the seller,  realization  on the  collateral  by the Fund may be
delayed or limited and the Fund may incur  additional  costs.  In such case, the
Fund will be subject to risks  associated  with  changes in market  value of the
collateral securities. The Fund intends to enter into repurchase agreements only
with banks and broker/dealers believed to present minimal credit risks.

   The High Yield Fund may also enter into reverse  repurchase  agreements  with
the same  parties  with whom it may enter into  repurchase  agreements.  Under a
reverse  repurchase  agreement,  the Fund  would  sell  securities  and agree to
repurchase  them at a  particular  price at a future  date.  Reverse  repurchase
agreements involve the risk that the market value of the securities  retained in
lieu of sale by the Fund may decline below the price of the  securities the Fund
has sold but is obligated to  repurchase.  In the event the buyer of  securities
under a reverse repurchase  agreement files for bankruptcy or becomes insolvent,
such buyer or its  trustee or  receiver  may  receive  an  extension  of time to
determine whether to enforce the Fund's obligation to repurchase the securities,
and the Fund's use of the  proceeds  of the  reverse  repurchase  agreement  may
effectively be restricted pending such decision.

   The High  Yield Fund also may enter  into  "dollar  rolls," in which the Fund
sells  fixed  income   securities   for  delivery  in  the  current   month  and
simultaneously  contracts to repurchase substantially similar (same type, coupon
and maturity) securities on a specified future date. During the roll period, the
Fund would forego principal and interest paid on such securities. The Fund would
be compensated by the difference between the current sales price and the forward
price for the future  purchase,  as well as by the  interest  earned on the cash
proceeds of the initial sale.  See  "Investment  Objectives and Policies" in the
Statement of Additional Information.
   
INVESTMENT METHODS
    
   BORROWING  -- Each of the Funds may borrow  money  from banks as a  temporary
measure for emergency purposes, or to facilitate redemption requests.
   
   From time to time,  it may be  advantageous  for the  Funds to  borrow  money
rather than sell  existing  portfolio  positions  to meet  redemption  requests.
Accordingly,  the Funds may borrow from banks and the High Yield Fund may borrow
through reverse  repurchase  agreements and "roll"  transactions,  in connection
with meeting  requests for the  redemption  of Fund shares.  High Yield Fund may
borrow up to 33 1/3 percent;  Limited  Maturity  Bond,  Municipal  Bond and Cash
Funds may each borrow up to 10 percent;  and Corporate Bond and U.S.  Government
Fund may borrow up to 5 percent of total Fund assets.  To the extent that a Fund
purchases securities while it has outstanding borrowings,  it is using leverage,
i.e., using borrowed funds for investment. Leveraging will exaggerate the effect
on net asset value of any  increase or decrease in the market  value of a Fund's
portfolio.  Money borrowed for leveraging will be subject to interest costs that
may or may not be recovered by  appreciation  of the  securities  purchased;  in
certain cases,  interest costs may exceed the return  received on the securities
purchased.  A Fund also may be required to maintain  minimum average balances in
connection with such borrowing or to pay a commitment or other fee to maintain a
line of  credit;  either  of  these  requirements  would  increase  the  cost of
borrowing over the stated interest rate. It is not expected that Cash Fund would
purchase securities while it had borrowings outstanding.

   OPTIONS AND FUTURES  TRANSACTIONS -- In seeking to protect  against  interest
rate changes that are adverse to its present or prospective positions,  the High
Yield Fund may employ  certain risk  management  practices  involving the use of
options  and futures  contracts  and options on futures  contracts  on U.S.  and
foreign  government  securities.  The Municipal  Bond Fund may employ the use of
futures contracts on U.S. government  securities and municipal bond indices. The
High Yield Fund also may enter into  interest  rate and index swaps and purchase
or sell related caps,  floors and collars.  Investment in derivative  securities
will be utilized for hedging purposes and not for speculation. See "Swaps, Caps,
Floors and Collars" below. See also "Derivative Instruments: Options and Futures
Strategies" in

PROSPECTUS
================================================================================
the Statement of Additional Information. There can be no assurance that a Fund's
risk management practices will succeed.

   Certain  Funds may  purchase put and call options and write such options on a
"covered" basis on securities that are traded on recognized securities exchanges
and  over-the-counter  ("OTC")  markets.  The Fund will cause its  custodian  to
segregate cash or liquid securities having a value sufficient to meet the Fund's
obligations  under the  option.  The Funds  also may enter  into  interest  rate
futures  contracts  and purchase and write  options to buy and sell such futures
contracts,  to the extent permitted under regulations of the Commodities Futures
Trading  Commission  ("CFTC").  The Funds will not employ  these  practices  for
speculation;  however, these practices may result in the loss of principal under
certain conditions. In addition, certain provisions of the Internal Revenue Code
of 1986,  as amended  ("Code"),  limit the extent to which a Fund may enter into
forward  contracts or futures contracts or engage in options  transactions.  See
"Taxes" in the Statement of Additional Information.

   SWAPS,  CAPS,  FLOORS AND COLLARS -- High Yield Fund may enter into  interest
rate and index  swaps,  and the  purchase  or sale of related  caps,  floors and
collars. The Fund expects to enter into these transactions primarily to preserve
a return or spread on a particular  investment  or portion of its portfolio as a
technique for managing the portfolio's  duration (i.e., the price sensitivity to
changes in interest  rates) or to protect  against any  increase in the price of
securities the Fund anticipates  purchasing at a later date. The Fund intends to
use these  transactions as hedges and not as speculative  investments,  and will
not sell  interest  rate caps or floors if it does not own  securities  or other
instruments providing the income the Fund may be obligated to pay.

   Interest  rate swaps  involve the exchange by the Fund with another  party of
their  respective  commitments  to pay or  receive  interest  (for  example,  an
exchange of floating  rate payments for fixed rate  payments)  with respect to a
notional amount of principal.

   The  purchase  of a cap  entitles  the  purchaser  to receive  payments  on a
notional  principal  amount from the party  selling the cap to the extent that a
specified  index  exceeds a  predetermined  interest  rate.  The  purchase of an
interest  rate floor  entitles the  purchaser to receive  payments on a notional
principal amount from the party selling the floor to the extent that a specified
index  falls  below a  predetermined  interest  rate or  amount.  A collar  is a
combination  of a cap and a floor  that  preserves  a  certain  return  within a
predetermined range of interest rates or values.

   AMERICAN  DEPOSITARY  RECEIPTS  (ADRS) -- The High  Yield  Fund may invest in
sponsored ADRs. ADRs are  dollar-denominated  receipts issued  generally by U.S.
banks and  which  represent  the  deposit  with the bank of a foreign  company's
securities.  ADRs are publicly  traded on exchanges or  over-the-counter  in the
United  States.  Investors  should  consider  carefully  the  substantial  risks
involved in investing  in  securities  issued by  companies of foreign  nations,
which are in addition to the usual risks inherent in domestic  investments.  See
"Foreign Investment Risks," below.

   LENDING OF  PORTFOLIO  SECURITIES  -- Certain  Funds may lend  securities  to
broker-dealers,  institutional  investors,  or other persons to earn income. The
principal  risk  is the  potential  insolvency  of the  broker-dealer  or  other
borrower.  In this event,  the Fund could  experience  delays in recovering  its
securities and possibly capital losses. Any loan will be continuously secured by
collateral  at least equal to the value of the  security  loaned.  Such  lending
could result in delays in receiving additional  collateral or in the recovery of
the securities or possible loss of rights in the collateral  should the borrower
fail financially.
   
RISK FACTORS
    
   GENERAL  RISK  FACTORS  --  Each  Fund's  net  asset  value  will  fluctuate,
reflecting  fluctuations  in the market value of its  portfolio  positions.  The
value  of  fixed  income  securities  held  by the  Funds  generally  fluctuates
inversely with interest rate movements.  In other words,  bond prices  generally
fall as interest rates rise and generally  rise as interest  rates fall.  Longer
term bonds held by the Funds are subject to greater interest rate risk. There is
no assurance that any Fund will achieve its investment objective.

   FOREIGN  INVESTMENT RISK -- Investment in foreign  securities  involves risks
and  considerations  not  present in  domestic  investments.  Foreign  companies
generally  are  not  subject  to  uniform  accounting,  auditing  and  financial
reporting standards,  practices and requirements  comparable to those applicable
to  U.S.  companies.  The  securities  of  non-U.S.  issuers  generally  are not
registered  with the SEC,  nor are the issuers  thereof  usually  subject to the
SEC's reporting requirements.  Accordingly, there may be less publicly available
information about foreign  securities and issuers than is available with respect
to U.S.  securities and issuers.  A Fund's income and gains from foreign issuers
may be subject to non-U.S.  withholding or other taxes,  thereby  reducing their
income and gains. In addition, with respect to some foreign countries,  there is
the increased possibility of expropriation or confiscatory taxation, limitations
on the  removal  of funds or other  assets  of the  Fund,  political  or  social
instability,  or diplomatic  developments  which could affect the investments of
the Fund in those countries.  Moreover,  individual foreign economies may differ
favorably or  unfavorably  from the U.S.  economy in such  respects as growth of
gross  national  product,  rate  of  inflation,  rate  of  savings  and  capital
reinvestment, resource self-sufficiency and balance of payments positions.

SECURITY FUNDS
PROSPECTUS
================================================================================
   RISKS  ASSOCIATED WITH INVESTMENT IN EMERGING MARKETS -- Certain of the Funds
may invest in emerging  markets.  Because of the special risks  associated  with
investing in emerging  markets,  an investment in a Fund making such investments
should be considered  speculative.  Investors  are strongly  advised to consider
carefully the special risks involved in emerging markets,  which are in addition
to the usual risks of investing in developed  foreign  markets around the world.
Investing in emerging  markets  involves risks  relating to potential  political
economic  instability  within  such  markets  and the  risks  of  expropriation,
nationalization,  confiscation  of assets  and  property  or the  imposition  of
restrictions on foreign  investment and on repatriation of capital invested.  In
the event of such  expropriation,  nationalization  or other confiscation in any
emerging market, the Fund could lose its entire investment in that market.  Many
emerging  market  countries have  experienced  substantial,  and in some periods
extremely  high,  rates  of  inflation  for  many  years.  Inflation  and  rapid
fluctuations  in  inflation  rates have had and may  continue  to have  negative
effects on the  economies  and  securities  markets of certain  emerging  market
countries.  Economies in emerging markets  generally are dependent  heavily upon
international trade and, accordingly,  have been and may continue to be affected
adversely by trade barriers,  exchange controls, managed adjustments in relative
currency values and other  protectionist  measures  imposed or negotiated by the
countries with which they trade. These economies also have been and may continue
to be affected adversely by economic conditions in the countries with which they
trade.

   The securities markets of emerging countries are substantially  smaller, less
developed,  less liquid and more  volatile  than the  securities  markets of the
United States and other more  developed  countries.  Disclosure  and  regulatory
standards in many  respects  are less  stringent  than in the United  States and
other  major  markets.  There  also  may be a  lower  level  of  monitoring  and
regulation  of emerging  securities  markets and the  activities of investors in
such  markets,  and  enforcement  of  existing  regulations  has been  extremely
limited.  Investments may also be made in former communist countries. There is a
possibility that these countries may revert to communism. In addition, brokerage
commissions,  custodial  services  and other  costs  relating to  investment  in
foreign  markets  generally  are  more  expensive  than  in the  United  States,
particularly  with respect to emerging  markets.  Such  markets  have  different
settlement and clearance  procedures.  In certain  markets there have been times
when  settlements  have been  unable to keep pace with the volume of  securities
transactions, making it difficult to conduct such transactions. The inability of
a Fund to make intended  securities  purchases due to settlement  problems could
cause it to forego attractive investment opportunities.  Inability to dispose of
a portfolio security caused by settlement problems could result either in losses
to a Fund due to subsequent declines in value of the portfolio security or, if a
Fund has entered into a contract to sell the security,  could result in possible
liability to the purchaser.

   The risk also exists  that an  emergency  situation  may arise in one or more
emerging  markets as a result of which trading of securities may cease or may be
substantially  curtailed  and prices for a Fund's  portfolio  securities in such
markets may not be readily  available.  Section  22(e) of the 1940 Act permits a
registered investment company to suspend redemption of its shares for any period
during which an emergency exists, as determined by the SEC. Accordingly,  when a
Fund believes that appropriate  circumstances warrant, it will promptly apply to
the SEC for a  determination  that an  emergency  exists  within the  meaning of
Section  22(e) of the 1940  Act.  During  the  period  commencing  from a Fund's
identification  of such conditions  until the date of SEC action,  the portfolio
securities  of a Fund in the  affected  markets  will be valued at fair value as
determined  in good  faith by or under  the  direction  of the  Fund's  Board of
Directors.

   RISKS  ASSOCIATED WITH LOWER-RATED DEBT SECURITIES (JUNK BONDS) -- Certain of
the Funds may invest in higher  yielding  debt  securities  in the lower  rating
(higher risk) categories of the recognized rating services (commonly referred to
as "junk  bonds").  Debt rated BB, B, CCC, CC and C by S&P and rated Ba, B, Caa,
Ca and C by Moody's, is regarded, on balance, as predominantly  speculative with
respect  to the  issuer's  capacity  to pay  interest  and  repay  principal  in
accordance  with the terms of the  obligation.  For S&P, BB indicates the lowest
degree of speculation and C the highest degree of speculation.  For Moody's,  Ba
indicates  the  lowest  degree  of  speculation  and C  the  highest  degree  of
speculation.  While  such debt will  likely  have some  quality  and  protective
characteristics,  these are  outweighed  by large  uncertainties  or major  risk
exposures  to adverse  conditions.  Similarly,  debt rated Ba or BB and below is
regarded by the relevant rating agency as  speculative.  Debt rated C by Moody's
or S&P is the lowest  quality  debt that is not in default  as to  principal  or
interest  and such  issues so rated can be  regarded  as having  extremely  poor
prospects of ever attaining any real  investment  standing.  Such securities are
also  generally  considered  to be subject to greater  risk than higher  quality
securities  with  regard to a  deterioration  of  general  economic  conditions.
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality.  Rating agencies attempt to evaluate
the safety of principal  and interest  payments and do not evaluate the risks of
fluctuations  in market  value.  Also,  rating  agencies may fail to make timely
changes in credit quality in response to subsequent  events, so that an issuer's
current financial condition may be better or worse than a rating indicates.

================================================================================
   The market value of lower quality debt securities tend to reflect  individual
developments  of  the  issuer  to  a  greater  extent  than  do  higher  quality
securities,  which react  primarily  to  fluctuations  in the  general  level of
interest  rates.  In addition,  lower  quality debt  securities  tend to be more
sensitive to economic  conditions and generally  have more volatile  prices than
higher quality securities.  Issuers of lower quality securities are often highly
leveraged  and may not  have  available  to them  more  traditional  methods  of
financing.  For example,  during an economic  downturn or a sustained  period of
rising interest rates,  highly leveraged issuers of lower quality securities may
experience  financial  stress.  During such  periods,  such issuers may not have
sufficient  revenues to meet their interest  payment  obligations.  The issuer's
ability  to service  its debt  obligations  may also be  adversely  affected  by
specific  developments  affecting the issuer,  such as the issuer's inability to
meet specific  projected  business forecasts or the unavailability of additional
financing.  Similarly,  certain  emerging  market  governments  that issue lower
quality  debt  securities  are among the largest  debtors to  commercial  banks,
foreign  governments and supranational  organizations such as the World Bank and
may not be able or willing to make principal and/or interest  repayments as they
come due. The risk of loss due to default by the issuer is significantly greater
for the  holders  of  lower  quality  securities  because  such  securities  are
generally unsecured and are often subordinated to other creditors of the issuer.

   Lower quality debt  securities of corporate  issuers  frequently have call or
buy-back  features  which  would  permit  an issuer  to call or  repurchase  the
security from the Fund. If an issuer  exercises these  provisions in a declining
interest  rate market,  the Fund may have to replace the  security  with a lower
yielding security,  resulting in a decreased return for investors.  In addition,
the Fund may have difficulty disposing of lower quality securities because there
may be a thin trading  market for such  securities.  There may be no established
retail secondary market for many of these  securities,  and the Fund anticipates
that  such  securities  could be sold only to a limited  number  of  dealers  or
institutional  investors. The lack of a liquid secondary market also may have an
adverse  impact  on  market  prices  of such  instruments  and may  make it more
difficult  for the Fund to obtain  accurate  market  quotations  for purposes of
valuing the securities in the portfolio of the Fund.

   Adverse  publicity  and  investor  perceptions,   whether  or  not  based  on
fundamental  analysis,  may also  decrease  the  values and  liquidity  of lower
quality  securities,  especially in a thinly traded market.  The High Yield Fund
also may acquire lower quality debt securities during an initial underwriting or
may acquire lower quality debt  securities  which are sold without  registration
under applicable securities laws. Such securities involve special considerations
and risks.

   Factors  having  an  adverse  effect  on the  market  value  of  lower  rated
securities or their equivalents  purchased by the Fund will adversely impact net
asset value of the Fund.  See "Risk  Factors"  in the  Statement  of  Additional
Information.  In addition  to the  foregoing,  such  factors  may  include:  (i)
potential adverse publicity;  (ii) heightened sensitivity to general economic or
political  conditions;  and (iii) the likely  adverse impact of a major economic
recession.  The Fund  also may incur  additional  expenses  to the  extent it is
required to seek recovery upon a default in the payment of principal or interest
on its portfolio  holdings,  and the Fund may have limited legal recourse in the
event of a default.  Debt securities  issued by governments in emerging  markets
can differ from debt  obligations  issued by private  entities in that  remedies
from  defaults  generally  must  be  pursued  in the  courts  of the  defaulting
government,  and legal  recourse is  therefore  somewhat  diminished.  Political
conditions, in terms of a government's willingness to meet the terms of its debt
obligations,  also are of considerable  significance.  There can be no assurance
that the holders of commercial bank debt may not contest payments to the holders
of debt  securities  issued by governments  in emerging  markets in the event of
default by the governments under commercial bank loan agreements.

   The  Investment  Manager  will  attempt to  minimize  the  speculative  risks
associated with investments in lower quality  securities through credit analyses
and  by  carefully  monitoring  current  trends  in  interest  rates,  political
developments and other factors.  Nonetheless,  investors should carefully review
the  investment  objectives and policies of the Funds and consider their ability
to assume the  investment  risks  involved  before  making an  investment in the
Funds.

MANAGEMENT OF THE FUNDS
   
   The management of the Funds'  business and affairs is the  responsibility  of
the  Board of  Directors.  Security  Management  Company,  LLC (the  "Investment
Manager"), 700 Harrison Street, Topeka, Kansas, is responsible for selection and
management of the Funds'  portfolio  investments.  The  Investment  Manager is a
limited  liability  company which is ultimately  controlled by Security  Benefit
Life  Insurance  Company,  a life  insurance  company  with over $7.4 billion of
insurance in force.  The Investment  Manager also acts as investment  adviser to
Security Equity, Growth and Income, and Ultra Funds and SBL Fund. The Investment
Manager currently manages approximately $____ billion in assets.

   The Investment  Manager has engaged  Salomon  Brothers Asset  Management Inc.
("Salomon  Brothers"),  7 World Trade  Center,  New York,  NY 10048,  to provide
investment  advisory services to the Municipal Bond Fund.  Salomon Brothers is a
wholly-owned subsidiary of

================================================================================
Salomon Brothers  Holding Company,  Inc., which is wholly-owned by Salomon Smith
Barney Holdings,  Inc., which is, in turn, wholly-owned by Travelers Group, Inc.
Salomon  Brothers was  incorporated  in 1987 and together with Salomon  Brothers
affiliates in London, Frankfurt,  Tokyo and Hong Kong, provides a broad range of
investment  advisory services to various  individuals and institutional  clients
located  throughout  the  world and  serves as  investment  adviser  to  various
investment  companies.  Currently  Salomon  Brothers and its  affiliates  manage
approximately $26.6 billion in assets.

   Subject to the  supervision  and  direction of the Funds' Board of Directors,
the  Investment  Manager  manages the Fund  portfolios in  accordance  with each
Fund's  stated  investment  objective  and  policies  and makes  all  investment
decisions.  As to the Municipal Bond Fund, the Investment Manager supervises the
management of the Fund's portfolio by the  Sub-Adviser,  Salomon  Brothers.  The
Investment Manager has agreed that total annual expenses of the respective Funds
(including  for any fiscal year,  the  management  fee, but excluding  interest,
taxes,  brokerage  commissions,  extraordinary expenses and Class B distribution
fees) shall not for the Corporate Bond,  Limited Maturity Bond, U.S.  Government
and High Yield Funds exceed the level of expenses  which the Funds are permitted
to bear under the most restrictive  expense  limitation  imposed by any state in
which shares of the Fund are then qualified for sale and shall not for Cash Fund
exceed  one  percent  of each  Fund's  average  net  assets  for the year.  (The
Investment  Manager is not aware of any state that  currently  imposes limits on
the level of mutual fund expenses.) The Investment Manager has agreed that total
expenses of Municipal  Bond Fund  (including for any fiscal year, the management
fee, but excluding interest, taxes, extraordinary expenses and Class A and Class
B  distribution  fees)  shall not exceed one  percent of the Fund's  average net
assets for the year. The Investment  Manager will  contribute  such funds to the
Funds or waive such  portion of its  compensation  as may be necessary to insure
that  such  total  annual  expenses  do  not  exceed  any  such  limitation.  As
compensation for its management services,  the Investment Manager receives on an
annual  basis,  .5 percent of the average  daily net assets of  Corporate  Bond,
Limited  Maturity Bond,  U.S.  Government,  Municipal Bond and Cash Funds and .6
percent of the average  daily net assets of the High Yield  Fund,  computed on a
daily basis and payable monthly.

   The Investment Manager also acts as the  administrative  agent for the Funds,
and as such performs administrative  functions, and the bookkeeping,  accounting
and pricing  functions for the Funds.  For this service the  Investment  Manager
receives  on an annual  basis,  a fee of .09  percent of the  average  daily net
assets of Corporate Bond, Limited Maturity Bond, U.S. Government, High Yield and
Municipal  Bond Funds and .045  percent of the average  daily net assets of Cash
Fund,  calculated daily and payable monthly. The Investment Manager also acts as
the  transfer  agent and  dividend  disbursing  agent for the Funds.  The Funds'
expenses  include  fees paid to the  Investment  Manager as well as  expenses of
brokerage   commissions,   interest,   taxes,  Class  B  distribution  fees  and
extraordinary expenses approved by the Board of Directors of the Funds.

   Like  other  mutual   funds,   as  well  as  other   financial  and  business
organizations  around the world,  the Funds could be  adversely  affected if the
computer systems used by the Investment Manager, and other service providers, in
performing its  administrative  functions do not properly  process and calculate
date-related information and data before, during and after January 1, 2000. Some
computer software and hardware systems currently cannot distinguish  between the
year 2000 and the year 1900 or some other date  because  for the way date fields
were encoded.

   The Investment  Manager has adopted a plan to be "Year 2000  Compliant"  with
respect to both its  internally  built  systems as well as systems  provided  by
external  vendors.  "Year 2000 Compliant"  means that systems and programs which
require  modification  will have the date fields expanded to include the century
information  and that for  interfaces to external  organizations  as well as new
systems  development the year portion of the date field will be expanded to four
digits using the format YYYYMMDD.  The Investment  Manager's overall approach to
addressing the Year 2000 issue is as follows:  (1) to inventory its internal and
external  hardware,  software,  telecommunications  and  data  transmissions  to
customers  and  conduct a risk  assessment  with  respect to the  impact  that a
failure of any such system would have on its business operations;  (2) to modify
or replace its internal  systems and obtain vendor  certifications  of Year 2000
compliance for systems  provided by vendors or replace such systems that are not
Year 2000  Compliant;  and (3) to  implement  and test its systems for Year 2000
compliance.  The Investment  Manager has completed the inventory of its internal
and external  systems and has made  substantial  progress toward  completing the
modification/replacement  of its internal  systems as well as towards  obtaining
Year 2000 Compliant  certifications  from its external vendors.  Overall systems
testing is scheduled to commence in December  1998 and extend into the first six
months of 1999.

   Although  the  Investment  Manager has taken steps to ensure that its systems
will function properly before, during and after the Year 2000, its key operating
systems and  information  sources are  provided by or through  external  vendors
which creates uncertainty to the extent the Investment Manager is relying on the
assurance  of such  vendors  as to  whether  their  systems  will  be Year  2000
Compliant. The costs or consequences of incomplete or untimely resolution of the
Year 2000  issue are  unknown to the  Investment  Manager at this time but could
have a

material  adverse  impact on the  operations  of the  Funds  and the  Investment
Manager.

   The Year 2000  problem is  expected  to impact  companies,  which may include
issuers of portfolio securities held by the Funds, to varying degrees based upon
various  factors,  including,  but not limited to, the  company's  industry  and
degree of technological sophistication. The Funds and the Investment Manager are
unable to  predict  what  impact,  if any,  the Year 2000  Problem  will have on
issuers of the portfolio securities held by the Funds.

   For the year ended December 31, 1997, the total expenses,  as a percentage of
average  net  assets,  were ___  percent for Class A and ___ percent for Class B
shares of Corporate Bond Fund; ___ percent for Class A and ___ percent for Class
B shares of U.S.  Government  Fund;  ___ percent for Class A and ___ percent for
Class B shares of Limited  Maturity Bond Fund; ___ percent of Class A shares and

   Security Distributors, Inc. (the "Distributor"), a wholly-owned subsidiary of
Security  Benefit  Group,  Inc., is principal  underwriter  for Corporate  Bond,
   Limited Maturity Bond, U.S. Government, High Yield and Municipal Bond Funds.
Shares of these Funds may be purchased through authorized investment dealers. In
addition, banks and other financial institutions that have an agreement with the
Distributor  may make shares of these Funds  available to their  customers.  The
minimum  initial  purchase must be $100 and  subsequent  purchases  must be $100
unless made through an Accumulation  Plan which allows  subsequent  purchases of
$20.

   Orders for the purchase of shares of Corporate Bond,  Limited  Maturity Bond,
U.S.  Government,  High Yield and  Municipal  Bond Funds will be confirmed at an
offering  price  equal to the net asset  value per share next  determined  after
receipt  of the order in proper  form by the  Distributor  (generally  as of the
close of the  Exchange on that day) plus the sales charge in the case of Class A
shares.  Orders  received  by dealers or other  firms  prior to the close of the
Exchange and received by the Distributor  prior to the close of its business day
will be  confirmed  at the  offering  price  effective  as of the  close  of the
Exchange on that day.
    
   Orders for shares  received  by  broker/dealers  prior to that day's close of
trading on the New York Stock Exchange and  transmitted to the Fund prior to its
close of  business  that day will  receive the  offering  price equal to the net
asset value per share  computed  at the close of trading on the  Exchange on the
same day plus, in the case of Class A shares, the sales charge.  Orders received
by  broker/dealers  after  that  day's  close of  trading  on the  Exchange  and
transmitted  to the Fund prior to the close of business on the next business day
will receive the next business day's offering price.
   
ALTERNATIVE PURCHASE OPTIONS

   Corporate  Bond,  Limited  Maturity  Bond,  U.S.  Government,  High Yield and
Municipal Bond Funds offer two classes of shares:
    
   CLASS A SHARES - FRONT-END LOAD OPTION.  Class A shares are sold with a sales
charge at the time of purchase. Class A shares are not subject to a sales charge
when they are redeemed  (except that shares sold in an amount of  $1,000,000  or
more without a front-end  sales charge will be subject to a contingent  deferred
sales  charge  for one  year.) See  Appendix  C on page 44 for a  discussion  of
possible reductions in the front-end sales charge.

   CLASS B SHARES - BACK-END  LOAD  OPTION.  Class B shares  are sold  without a
sales charge at the time of purchase, but are subject to a deferred sales charge
if they are redeemed  within five years of the date of purchase.  Class B shares
will automatically  convert tax-free to Class A shares at the end of eight years
after purchase.

   The decision as to which class is more  beneficial to an investor  depends on
the amount and intended length of the investment. Investors who would rather pay
the entire cost of distribution at the time of investment, rather than spreading
such cost over  time,  might  consider  Class A shares.  Other  investors  might
consider  Class B shares,  in which case 100  percent of the  purchase  price is
invested  immediately,  depending on the amount of the purchase and the intended
length of investment. The Funds will not normally accept any purchase of Class B
shares in the amount of $250,000 or more.

   Dealers or others receive different levels of compensation depending on which
class of shares they sell.

SECURITY INCOME AND MUNICIPAL BOND FUNDS' CLASS A DISTRIBUTION PLANS

   In addition to the sales charge  deducted  from Class A shares at the time of
purchase,  each of Corporate Bond, Limited Maturity Bond, U.S. Government,  High
Yield and Municipal Bond Funds is authorized, under a Distribution Plan pursuant
to  Rule  12b-1  under  the  Investment  Company  Act  of  1940  (the  "Class  A
Distribution Plan"), to use its assets to finance certain activities relating to
the  distribution of its shares to investors.  Each Fund's Plan permits payments
to be made by these  Funds to the  Distributor,  to finance  various  activities
relating to the  distribution  of their Class A shares to investors,  including,
but  not  limited  to,  the  payment  of   compensation   (including   incentive
compensation  to  securities  dealers  and  other  financial   institutions  and
organizations)  to obtain  various  distribution-related  and/or  administrative
services for the Funds.

   Under each Fund's Class A Distribution Plan, a monthly payment is made to the
Distributor  in an amount  computed  at an  annual  rate of .25  percent  of the
average daily net asset value of Corporate  Bond,  Limited  Maturity Bond,  U.S.
Government,   High  Yield  and  Municipal  Bond  Funds'  Class  A  shares.   The
distribution  fee is  charged to each Fund in  proportion  to the  relative  net
assets of their Class A shares.  The distribution  fees collected may be used by
Corporate Bond,  Limited Maturity Bond, U.S.  Government and High Yield Funds to
finance joint distribution activities, for example joint advertisements, and the
costs of such joint  activities  will be allocated among the Funds on a fair and
equitable  basis,  including  on the basis of the  relative  net assets of their
Class A shares.

   Each Class A Distribution  Plan  authorizes  payment by the Class A shares of
these Funds of the cost of preparing, printing and distributing prospectuses and
Statements  of  Additional   Information   to   prospective   investors  and  of
implementing and operating the Plan.

   In  addition,  compensation  to  securities  dealers  and others is paid from
distribution  fees at an annual  rate of .25  percent of the  average  daily net
asset value of Class A shares sold by such dealers and remaining  outstanding on
the Funds' books to obtain certain administrative  services for the Funds' Class
A  stockholders.  The  services  include,  among other  things,  processing  new
stockholder   account   applications  and  serving  as  the  primary  source  of
information to customers in answering  questions  concerning the Funds and their
transactions  with the Funds.  The  Distributor is also  authorized to engage in
advertising,  the  preparation and  distribution  of sales  literature and other
promotional  activities on behalf of Corporate Bond, Limited Maturity Bond, U.S.
Government,  High Yield and Municipal Bond Funds.  Other promotional  activities
which may be financed pursuant to the Plans include (i)  informational  meetings
concerning  these Funds for  registered  representatives  interested  in selling
shares of the Funds and (ii) bonuses or  incentives  offered to all or specified
dealers on the basis of sales of a specified  minimum  dollar  amount of Class A
shares  of  these  Funds  by the  registered  representatives  employed  by such
dealer(s).  The expenses  associated with the foregoing  activities will include
travel expenses,  including lodging.  Additional  information may be obtained by
referring to the Funds' Statement of Additional Information.

   Corporate  Bond,  Limited  Maturity  Bond,  U.S.  Government,  High Yield and
Municipal Bond Funds' Class A Distribution Plan may be terminated at any time by
vote of the  directors  of  Income  Fund or  Municipal  Bond  Fund,  who are not
interested  persons  of the  Fund as  defined  in the  1940  Act or by vote of a
majority  of  the  outstanding  Class  A  shares.  In  the  event  the  Class  A
Distribution  Plans are  terminated  by the Funds' Class A  stockholders  or the
Board of Directors,  the payments made to the Distributor  pursuant to the Plans
up to that time would be retained by the Distributor.  Any expenses  incurred by
the   Distributor  in  excess  of  those  payments  would  be  absorbed  by  the
Distributor.

CLASS B SHARES

   Class B shares of Corporate Bond,  Limited  Maturity Bond,  U.S.  Government,
High Yield and Municipal  Bond Funds are offered at net asset value,  without an
initial sales charge. With certain exceptions, these Funds may impose a deferred
sales  charge  on  Class B  shares  redeemed  within  five  years of the date of
purchase. No deferred sales charge is imposed on amounts redeemed thereafter. If
imposed,  the deferred  sales charge is deducted  from the  redemption  proceeds
otherwise payable. The deferred sales charge is retained by the Distributor.
    
   Whether a contingent  deferred  sales charge is imposed and the amount of the
charge will depend on the number of years since the stockholder  made a purchase
payment  from  which an amount is being  redeemed,  according  to the  following
schedule:

   Class B shares (except shares purchased through the reinvestment of dividends
and other  distributions paid with respect to Class B shares) will automatically
convert on the eighth  anniversary  of the date such  shares were  purchased  to
Class A shares which are subject to a lower  distribution  fee.  This  automatic
conversion of Class B shares will take place  without  imposition of a front-end
sales charge or exchange fee. (Conversion of Class B shares represented by stock
certificates will require the return of the stock certificates to the Investment
Manager.)  All shares  purchased  through  reinvestment  of dividends  and other
distributions paid with respect to Class B shares  ("reinvestment  shares") will
be considered to be held in a separate subaccount.  Each time any Class B shares
(other than those held in the subaccount)  convert to Class A shares, a pro rata
portion of the  reinvestment  shares held in the subaccount will also convert to
Class A shares.  Class B shares so  converted  will no longer be  subject to the
higher  expenses borne by Class B shares.  Because the net asset value per share
of the Class A shares  may be higher or lower than that of the Class B shares at
the  time  of  conversion,  although  the  dollar  value  will  be the  same,  a
stockholder  may receive  more or less Class A shares than the number of Class B
shares  converted.  Under  current  law,  it is the Funds'  opinion  that such a
conversion  will not constitute a taxable event under federal income tax law. In
the event that this ceases to be the case,  the Board of Directors will consider
what action,  if any, is  appropriate  and in the best  interests of the Class B
stockholders.
   
CLASS B DISTRIBUTION PLAN

   Each of Corporate Bond,  Limited Maturity Bond, U.S.  Government,  High Yield
and  Municipal  Bond Funds bears some of the costs of selling its Class B shares
under a  Distribution  Plan adopted with respect to its Class B shares ("Class B
Distribution  Plan") pursuant to Rule 12b-1 under the Investment  Company Act of
1940 ("1940  Act").  Each Fund's Plan provides for payments at an annual rate of
1.00 percent of the average daily net asset value of its Class B shares. Amounts
paid by the Funds are  currently  used to pay  dealers and other firms that make
Class B shares  available to their  customers  (1) a  commission  at the time of
purchase  normally equal to 4.00 percent of the value of each share sold and (2)
a  service  fee  payable  for the  first  year,  initially,  and for  each  year
thereafter, quarterly, in an amount equal to .25 percent annually of the average
daily net asset value of Class B shares sold by such dealers and other firms and
remaining outstanding on the books of the Funds.
    
   NASD Rules limit the aggregate amount that each of the Funds may pay annually
in  distribution  costs for the sale of its Class B shares  to 6.25  percent  of
gross sales of Class B shares since the inception of the Distribution Plan, plus
interest at the prime rate plus one percent on such amount (less any  contingent
deferred sales charges paid by Class B  stockholders  to the  Distributor).  The
Distributor  intends,  but is not  obligated,  to  continue  to apply or  accrue
distribution  charges incurred in connection with the Class B Distribution  Plan
which exceed current annual payments permitted to be received by the Distributor
from the Funds.  The  Distributor  intends to seek full  payment of such charges
from the Fund (together with annual interest  thereon at the prime rate plus one
percent) at such time in the future as, and to the extent that,  payment thereof
by the Funds would be within permitted limits.

   Each Fund's Class B  Distribution  Plan may be terminated at any time by vote
of its  directors who are not  interested  persons of the Fund as defined in the
1940 Act or by vote of a  majority  of the  outstanding  Class B shares.  In the
event the Class B Distribution Plan is terminated by the Class B stockholders or
the Funds' Board of Directors,  the payments made to the Distributor pursuant to
the Plan up to that time would be  retained  by the  Distributor.  Any  expenses
incurred by the Distributor in excess of those payments would be absorbed by the
Distributor.  The Funds make no  payments in  connection  with the sale of their
Class B shares other than the distribution fee paid to the Distributor.
   
CALCULATION AND WAIVER OF CONTINGENT DEFERRED SALES CHARGES
    
   Any  contingent  deferred  sales charge  imposed upon  redemption  of Class A
shares  (purchased  in an amount of  $1,000,000 or more) and Class B shares is a
percentage  of the lesser of (1) the net asset  value of the shares  redeemed or
(2) the net cost of such shares. No contingent  deferred sales charge is imposed
upon redemption of amounts derived from (1) increases in the value above the net
cost of such  shares due to  increases  in the net asset  value per share of the
Fund; (2) shares acquired  through  reinvestment of income dividends and capital
gain distributions;  or (3) Class A shares (purchased in an amount of $1,000,000
or more)  held for more than one year or Class B shares  held for more than five
years.  Upon  request  for  redemption,  shares not  subject  to the  contingent
deferred  sales  charge  will be  redeemed  first.  Thereafter,  shares held the
longest will be the first to be redeemed.

   The contingent  deferred sales charge is waived: (1) following the death of a
stockholder  if  redemption  is made within one year after  death;  (2) upon the
disability (as

defined in Section 72(m)(7) of the Internal Revenue Code) of a stockholder prior
to age 65 if redemption is made within one year after the  disability,  provided
such  disability  occurred  after the  stockholder  opened the  account;  (3) in
connection with required minimum distributions in the case of an IRA, SAR-SEP or
Keogh or any other  retirement plan qualified  under section  401(a),  401(k) or
403(b) of the Code; and (4) in the case of  distributions  from retirement plans
qualified under section 401(a) or 401(k) of the Internal Revenue Code due to (i)
returns of excess contributions to the plan, (ii) retirement of a participant in
the  plan,  (iii) a loan  from the  plan  (repayment  of  loans,  however,  will
constitute  new sales for purposes of assessing the  contingent  deferred  sales
charge, (iv) "financial  hardship" of a participant in the plan, as that term is
defined in Treasury Regulation section 1.401(k)1(d)(2),  as amended from time to
time, (v) termination of employment of a participant in the plan, (vi) any other
permissible  withdrawal  under the terms of the plan.  The  contingent  deferred
sales charge will also be waived in the case of redemptions of Class B shares of
the  Funds  pursuant  to  a  systematic   withdrawal  program.  See  "Systematic
Withdrawal Program," page 33 for details.
   
ARRANGEMENTS WITH BROKER-DEALERS AND OTHERS

   The Distributor,  from time to time, will provide  promotional  incentives or
pay a bonus to certain dealers whose  representatives  have sold or are expected
to sell significant  amounts of the Corporate Bond,  Limited Maturity Bond, U.S.
Government,  High Yield and  Municipal  Bond Funds  and/or  certain  other Funds
managed by the Investment  Manager.  Such  promotional  incentives  will include
payment for  attendance  (including  travel and lodging  expenses) by qualifying
registered  representatives (and members of their families) at sales seminars at
luxury  resorts  within or outside the United  States.  Bonus  compensation  may
include  reallowance  of the  entire  sales  charge and may also  include,  with
respect to Class A shares,  an amount which exceeds the entire sales charge and,
with respect to Class B shares, an amount which exceeds the maximum  commission.
The  Distributor,   or  the  Investment  Manager,  may  also  provide  financial
assistance to certain dealers in connection with conferences,  sales or training
programs  for their  employees,  seminars  for the  public,  advertising,  sales
campaigns, and/or shareholder services and programs regarding one or more of the
funds managed by the Investment Manager.  Certain of the promotional  incentives
or bonuses may be financed  by  payments to the  Distributor  under a Rule 12b-1
Distribution Plan. The payment of promotional incentives and/or bonuses will not
change the price an  investor  will pay for shares or the amount  that the Funds
will receive from such sale. No compensation will be offered to the extent it is
prohibited  by the laws of any  state  or  self-regulatory  agency,  such as the
National  Association of Securities  Dealers,  Inc.  ("NASD").  A Dealer to whom
substantially  the entire  sales  charge on Class A shares is  reallowed  may be
deemed to be an "underwriter" under federal securities laws.
    
   The Distributor  also may pay banks and other  financial  services firms that
facilitate  transactions  in shares of the Funds for their clients a transaction
fee up to the level of the  payments  made  allowable to dealers for the sale of
such  shares as  described  above.  Banks  currently  are  prohibited  under the
Glass-Steagall Act from providing certain underwriting or distribution services.
If banking firms were prohibited from acting in any capacity or providing any of
the  described  services,  the Funds' Board of  Directors  would  consider  what
action, if any, would be appropriate.

   In  addition,  state  securities  laws on this  issue  may  differ  from  the
interpretations  of  federal  law  expressed  herein  and  banks  and  financial
institutions may be required to register as dealers pursuant to state law.
   
   The Investment  Manager or Distributor also may pay a marketing  allowance to
dealers who meet  certain  eligibility  criteria.  This  allowance  is paid with
reference to new sales of shares of Corporate Bond,  Limited Maturity Bond, U.S.
Government,  High  Yield and  Municipal  Bond Funds in a  calendar  year.  To be
eligible for this allowance in any given year, the dealer must sell a minimum of
$2,000,000  of Class A and  Class B  shares  during  that  year.  The  marketing
allowance  ranges  from .15  percent  to .75  percent  of  aggregate  new  sales
depending upon the volume of shares sold. See the Funds' Statement of Additional
Information for more detailed information about the marketing allowance.
    
CASH FUND

   Shares of Cash Fund are offered at net asset value next  determined  after an
order is  accepted.  There is no sales  charge  or  load.  The  minimum  initial
investment in Cash Fund is $100 for each account.  Subsequent investments may be
made in any amount of $20 or more. Cash Fund purchases may be made in any of the
following ways:

1.  BY MAIL

    (a)  A check or negotiable bank draft should be sent to:

         Security Cash Fund
         P.O. Box 2548
         Topeka, Kansas 66601

    (b)  Make check or draft payable to "SECURITY CASH FUND."

    (c)  For initial investment include a completed investment application found
         on page 42 of this prospectus.

2.  BY WIRE

    (a)  Call the Fund to advise  of the  investment.  The Fund  will  supply an
         account  number  at the  time of the  initial  investment  and  provide
         instructions for having your bank wire federal funds.

    (b)  For an initial  investment,  you must also send a completed  investment
         application to the Fund.

3.  THROUGH BROKER/DEALERS

   Investors may, if they wish, invest in Cash Fund by purchasing shares through
registered  broker/dealers.  Such broker/dealers who process orders on behalf of
their customers may charge a fee for their services.  Investments  made directly
without the assistance of a broker/dealer are without charge.

   Since Cash Fund invests in money market  securities  which require  immediate
payment in federal funds,  monies  received from the sales of its shares must be
monies held by a commercial bank and be on deposit at one of the Federal Reserve
Banks.  A record date for each  stockholder's  investment  is  established  each
business day and used to distribute  the following  day's  dividend.  If federal
funds are received prior to 2:00 p.m. (Central time) the investment will be made
on that day and the investor will receive the following day's dividend.  Federal
funds  received  after 2:00 p.m. on any business day will not be invested  until
the following  business day. The Fund will not be responsible  for any delays in
the wire transfer system.  All checks are accepted subject to collection at full
face value in United States funds and must be drawn in United States  dollars on
a United States bank.

   The Investment Manager may, at its expense,  pay a service fee to dealers who
satisfy certain criteria established by the Investment Manager from time to time
relating  to the volume of their  sales of Cash Fund  during  prior  periods and
certain other factors, including providing certain services to their clients who
are stockholders of the Fund. Currently,  service fees are paid on the aggregate
value of Cash Fund accounts opened after July 31, 1990, at the following  annual
rate:  .25 percent of  aggregate  net asset value for amounts of  $1,000,000  or
more.
   
PURCHASES AT NET ASSET VALUE

   Class  A  shares  of  Corporate  Bond,   Limited  Maturity  Bond  Fund,  U.S.
Government,  High Yield and  Municipal  Bond Funds may be purchased at net asset
value  by (1)  directors,  officers  and  employees  of the  Funds,  the  Funds'
Investment Manager or Distributor; directors, officers and employees of Security
Benefit  Life  Insurance  Company and its  subsidiaries;  agents  licensed  with
Security Benefit Life Insurance  Company;  spouses or minor children of any such
agents; as well as the following  relatives of any such directors,  officers and
employees  (and  their  spouses):  spouses,  grandparents,   parents,  children,
grandchildren,  siblings,  nieces and nephews;  (2) any trust,  pension,  profit
sharing or other benefit plan  established by any of the foregoing  corporations
for  persons   described   above;   (3)  retirement   plans  where  third  party
administrators  of such plans have entered into  certain  arrangements  with the
Distributor  or its  affiliates  provided that no commission is paid to dealers;
and (4) officers,  directors,  partners or registered representatives (and their
spouses and minor children) of broker/dealers  who have a selling agreement with
the Distributor. Such sales are made upon the written assurance of the purchaser
that the purchase is made for investment  purposes and that the securities  will
not be transferred  or resold except  through  redemption or repurchase by or on
behalf of the Funds.

   Class A shares of Corporate Bond,  Limited  Maturity Bond,  U.S.  Government,
High Yield and  Municipal  Bond Funds may also be  purchased  at net asset value
when the purchase is made on the  recommendation of (i) a registered  investment
adviser,  trustee or financial intermediary who has authority to make investment
decisions on behalf of the investor;  or (ii) a certified  financial  planner or
registered  broker-dealer  who either charges periodic fees to its customers for
financial  planning,  investment  advisory  or  asset  management  services,  or
provides  such services in connection  with the  establishment  of an investment
account for which a comprehensive "wrap fee" is imposed. The Distributor must be
notified when a purchase is made that qualifies under this provision.

TRADING PRACTICES AND BROKERAGE

   The portfolio  turnover  rate for the Corporate  Bond,  U.S.  Government  and
Municipal Bond Funds, respectively, for the fiscal year ended December 31, 1997,
was as follows:  Corporate Bond Fund - ___ percent;  U.S.  Government fund - ___
percent;  Limited  Maturity  Bond  Fund - ___  percent;  High  Yield  Fund - ___
percent;  Municipal  Bond Fund - ___  percent.  The  Corporate  Bond and Limited
Maturity Bond Funds'  portfolio  turnover rate  generally is expected to be less
than 100 percent,  and that of the U.S.  Government Fund may exceed 100 percent,
but is not  expected to do so. The  portfolio  turnover  rate for the High Yield
Fund may exceed 100  percent  but it is  generally  not  expected  to exceed 150
percent.  Higher portfolio turnover subjects a fund to increased brokerage costs
and may, in some cases, have adverse tax effects on a fund or its stockholders.
    
   Cash Fund is expected to have a high portfolio turnover rate due to the short
maturities of its portfolio  securities;  this should not,  however,  affect the
Fund's income or net asset value since  brokerage  commissions  are not normally
paid in connection with the purchase or sale of money market instruments.

   Transactions in portfolio  securities are effected in the manner deemed to be
in the best interests of each Fund. In selecting a broker or dealer to execute a
specific  transaction,  all  relevant  factors  will  be  considered.  Portfolio
transactions  may be directed to brokers who furnish  investment  information or
research services to the Investment Manager or who sell shares of the Funds. The
Investment Manager may, consistent with the NASD Rules of Fair Practice,

consider sales of shares of the Fund in the selection of a broker.

   Securities  held by the Funds may also be held by other  investment  advisory
clients of the Investment Manager,  including other investment companies, and by
the Investment Manager's parent company, Security Benefit Life Insurance Company
("SBL").  Purchases  or  sales of the same  security  occurring  on the same day
(which may include  orders from SBL) may be aggregated  and executed as a single
transaction,  subject  to the  Investment  Manager's  obligation  to  seek  best
execution.  Aggregated  purchases or sales are generally  effected at an average
price and on a pro rata  basis  (transaction  costs will also be shared on a pro
rata basis) in  proportion to the amounts  desired to be purchased or sold.  See
the Funds' Statement of Additional  Information for a more detailed  description
of aggregated transactions.

HOW TO REDEEM SHARES

   A stockholder may redeem shares at the net asset value next determined  after
the time when such shares are tendered for redemption.

   Shares will be redeemed on request of the  stockholder in proper order to the
Funds' Investment Manager, Security Management Company, LLC, which serves as the
Funds'  transfer  agent.  A request is made in proper  order by  submitting  the
following items to the Investment Manager:  (1) a written request for redemption
signed by all registered owners exactly as the account is registered,  including
fiduciary  titles,  if any,  and  specifying  the account  number and the dollar
amount or number of shares to be redeemed;  (2) a guarantee of all signatures on
the written request or on the share certificate or accompanying stock power; (3)
any share certificates issued for any of the shares to be redeemed;  and (4) any
additional  documents  which  may be  required  by the  Investment  Manager  for
redemption by corporations or other  organizations,  executors,  administrators,
trustees,  custodians  or the like.  Transfers of shares are subject to the same
requirements.  The signature guarantee must be provided by an eligible guarantor
institution,  such as a bank, broker, credit union, national securities exchange
or savings association. A signature guarantee is not required for redemptions of
$10,000 or less,  requested by and payable to all  stockholders of record for an
account,  to be sent to the address of record.  The Investment  Manager reserves
the right to reject any signature  guarantee  pursuant to its written procedures
which may be revised in the future.  To avoid delay in  redemption  or transfer,
stockholders  having questions should contact the Investment  Manager by calling
1-800-888-2461, extension 3127.

   The redemption  price will be the net asset value of the shares next computed
after the  redemption  request in proper  order is  received  by the  Investment
Manager.  In addition,  stockholders of Cash Fund will receive any undistributed
dividends, including any dividend declared on the day of the redemption. Payment
of the amount due on redemption, less any applicable deferred sales charge, will
be made by check, or by wire at the sole  discretion of the Investment  Manager,
within seven days after receipt of the redemption  request in proper order. If a
wire transfer is  requested,  the  Investment  Manager must be provided with the
name and  address of the  stockholder's  bank as well as the  account  number to
which  payment  is to be  wired.  Checks  will be  mailed  to the  stockholder's
registered  address  (or  as  otherwise  directed).  Remittance  by  wire  (to a
commercial  bank account in the same name(s) as the shares are  registered),  by
certified or cashier's  check,  or by express mail,  if requested,  will be at a
charge of $15, which will be deducted from the redemption proceeds.

   Cash Fund offers  redemption  by check.  If blank checks are requested on the
Checking  Privilege  Request Form, the Fund will make a supply  available.  Such
checks may be drawn in any amount of $100 or more.  When a check is presented to
Cash Fund for payment,  it will redeem  sufficient full and fractional shares to
cover the check.  Such  shares  will be  redeemed  at the price next  calculated
following  receipt of any check which does not exceed the value of the  account.
The price of Cash Fund shares may fluctuate from day-to-day and the price at the
time of redemption, by check or otherwise, may be less than the amount invested.
Redemption by check is not available if any shares are held in certificate  form
or if shares  being  redeemed  have not been on the Fund's books for at least 15
days.  The  availability  of  checkwriting  privileges  may  encourage  multiple
redemptions on an account.  Whenever multiple  redemptions occur, the difficulty
of monitoring the shareholder's cost basis in his or her investment increases.

   In addition to the  foregoing  redemption  procedures,  the Funds  repurchase
shares from  broker/dealers  at the price determined as of the close of business
on the day such  offer is  confirmed.  Dealers  may charge a  commission  on the
repurchase of shares.

   At  various  times,  requests  may be made to redeem  shares  for which  good
payment has not yet been received.  Accordingly,  payment of redemption proceeds
may be  delayed  until  such time as good  payment  has been  collected  for the
purchase  of the  shares  in  question,  which  may take up to 15 days  from the
purchase date.

   Requests  may also be made to  redeem  shares  in an  account  for  which the
stockholder's  tax  identification  number has not been provided.  To the extent
permitted by law, the  redemption  proceeds from such an account will be reduced
by $50 to reimburse for the penalty imposed by the Internal  Revenue Service for
failure to report the tax identification number.

TELEPHONE REDEMPTIONS

   Stockholders  may  redeem  uncertificated  shares in amounts up to $10,000 by
telephone  request,  provided that the  stockholder  has completed the Telephone
Redemption  section of the application or a Telephone  Redemption form which may
be obtained from the Investment Manager.  The proceeds of a telephone redemption
will  be sent to the  stockholder  at his or her  address  as set  forth  in the
application or in a subsequent written authorization with a signature guarantee.
Once  authorization has been received by the Investment  Manager,  a stockholder
may redeem  shares by calling the Funds at (800)  888-2461,  extension  3127, on
weekdays (except  holidays) between the hours of 7:00 a.m. and 6:00 p.m. Central
time.  Redemption requests received by telephone after the close of the New York
Stock Exchange  (normally 3 p.m. Central time) will be treated as if received on
the next  business  day.  Telephone  redemptions  are not  accepted  for IRA and
403(b)(7)  accounts.   A  stockholder  who  authorizes   telephone   redemptions
authorizes the  Investment  Manager to act upon the  instructions  of any person
identifying  themselves as the owner of the account or the owner's  broker.  The
Investment  Manager has  established  procedures  to confirm  that  instructions
communicated  by telephone  are genuine and will be liable for any losses due to
fraudulent  or  unauthorized  instructions  if  it  fails  to  comply  with  its
procedures.   The  Investment  Manager's  procedures  require  that  any  person
requesting a telephone  redemption  provide the account  registration and number
and the  owner's  tax  identification  number,  and  such  instructions  must be
received on a recorded line. Neither the Fund, the Investment  Manager,  nor the
Distributor shall be liable for any loss, liability, cost or expense arising out
of any telephone  redemption  request,  provided the Investment Manager complied
with its procedures.  Thus, a stockholder who authorizes  telephone  redemptions
may  bear  the risk of loss  from a  fraudulent  or  unauthorized  request.  The
telephone redemption privilege may be changed or discontinued at any time by the
Investment Manager or the Funds.

   During periods of severe market or economic conditions, telephone redemptions
may be difficult to implement and  stockholders  should make redemptions by mail
as described in "How to Redeem Shares" on page 28.
   
DIVIDENDS AND TAXES

   It is the policy of Corporate Bond,  Limited Maturity Bond, U.S.  Government,
High Yield and Municipal Bond Funds to pay dividends from net investment  income
monthly.  It is the  policy of  Corporate  Bond,  Limited  Maturity  Bond,  U.S.
Government,  High Yield and Municipal Bond Funds to distribute  realized capital
gains (if any) in excess of any capital losses and capital loss  carryovers,  at
least once a year.  Because Class A shares of Corporate Bond,  Limited  Maturity
Bond,  U.S.  Government,  High Yield and  Municipal  Bond Funds bear most of the
costs of  distribution  of such  shares  through  payment of a  front-end  sales
charge,  while  Class B shares of these  Funds bear such costs  through a higher
distribution fee, expenses  attributable to Class B shares,  generally,  will be
higher and as a result, income distributions paid by these Funds with respect to
Class B shares  generally  will be lower than those paid with respect to Class A
shares. Any such dividend payment or capital gains distribution will result in a
decrease of the net asset value of the shares in an amount  equal to the payment
or distribution. All dividends and distributions are automatically reinvested on
the payable date in shares of the Funds at net asset value as of the record date
(reduced  by an amount  equal to the  amount of the  dividend  or  distribution)
unless  the  Investment  Manager  is  previously  notified  in  writing  by  the
stockholder that such dividends or  distributions  are to be received in cash. A
stockholder  may also request that such dividends or  distributions  be directly
deposited to the  stockholder's  bank account.  Dividends or distributions  paid
with respect to Class A shares and  received in cash may,  within 30 days of the
payment date, be reinvested without a sales charge.
    
   Each of Corporate Bond, Limited Maturity Bond, U.S. Government and High Yield
Funds (series of Income Fund),  is to be treated  separately in determining  the
amounts of income and capital gains distributions. For this purpose, each series
will reflect only the income and gains, net of losses, of that series.
   
   The following summarizes certain federal income tax considerations  generally
affecting  the Funds and their  stockholders.  See the  "Statement of Additional
Information"  for  further  details.  No  attempt  is made to present a detailed
explanation  of the tax  treatment of the Funds or their  stockholders,  and the
discussion  here and in the Statement of Additional  Information is not intended
as a substitute  for careful tax planning.  The discussion is based upon present
provisions of the Internal  Revenue Code of 1986,  as amended (the "Code"),  the
regulations  promulgated  thereunder,  and  judicial and  administrative  ruling
authorities,   all  of  which  are  subject  to  change,  which  change  may  be
retroactive.  Prospective  investors  should consult their own tax advisors with
regard  to  the  federal  tax  consequences  of  the  purchase  ownership,   and
disposition of Fund shares,  as well as the tax  consequences  arising under the
laws of any state, foreign country, or other taxing jurisdiction.
    
   Certain  requirements  relating to the qualification of a Fund as a regulated
investment  company  may limit the extent to which a Fund will be able to engage
in certain  investment  practices,  including  transactions in options,  futures
contracts,   forwards,   swaps  and  other   types  of   derivative   securities
transactions. In addition, if a Fund were

SECURITY FUNDS
PROSPECTUS
================================================================================
unable to dispose of portfolio securities due to settlement problems relating to
foreign  investments  or due to the holding of illiquid  securities,  the Fund's
ability to qualify as a regulated investment company might be affected.

   Cash Fund's  policy is to declare  daily  dividends  of all of its net income
each day the Fund is open for  business,  increased or decreased by any realized
capital  gains  or  losses.   Such  dividends  are  automatically   credited  to
stockholder  accounts.  Unless  stockholders  elect to receive  cash,  they will
receive such  dividends in  additional  shares on the last  business day of each
month at the net asset  value on that  date.  If cash  payment of  dividends  is
desired,  investors may so indicate in the appropriate  section of the Cash Fund
application  and  checks  will be mailed  within  five  business  days after the
beginning  of the  month.  Confirmation  of  Cash  Fund  dividends  will be sent
quarterly,  and confirmations of purchases and redemptions will be sent monthly.
The  amount  of  dividends  may  fluctuate  from  day to day.  If on any day net
realized or unrealized losses on portfolio  securities exceed Cash Fund's income
for that day and results in a decline of net asset value per share below  $1.00,
the  dividend  for that day will be omitted  until the net asset value per share
subsequently returns to $1.00 per share.

   The Funds will not pay  dividends or  distributions  of less than $25 in cash
but will automatically reinvest them.

   Each of the Funds  intends  to qualify as a  "regulated  investment  company"
under the  Internal  Revenue  Code.  Such  qualification  generally  removes the
liability for federal  income taxes from the Fund,  and makes federal income tax
upon  income and  capital  gains  generated  by a Fund's  investments,  the sole
responsibility of its stockholders provided the Fund continues to so qualify and
distributes  all of its net investment  income and net realized  capital gain to
its stockholders. Furthermore, the Funds generally will not be subject to excise
taxes imposed on certain regulated  investment companies provided that each Fund
distributes 98 percent of its ordinary  income and 98 percent of its net capital
gain income each year.
   
   Municipal Bond Fund intends to qualify to pay "exempt interest  dividends" to
its  stockholders.  Municipal Bond Fund will be so qualified if, at the close of
each quarter of its taxable  year, at least 50 percent of the value of its total
assets  consists of  securities  on which the interest  payments are exempt from
federal tax. To the extent that Municipal Bond Fund's  dividends  distributed to
stockholders  are derived from  earnings on interest  income exempt from federal
tax and are designated as "exempt-interest  dividends" by the Fund, they will be
excludable  from a  stockholder's  gross income for federal income tax purposes.
The Fund will  inform  stockholders  annually  as to the  portion of that year's
distributions from the Fund which constituted "exempt-interest dividends."

   Although  exempt-interest  dividends  paid by the Municipal Bond Fund will be
excluded by shareholders of the Fund from their gross income for regular federal
income tax  purposes,  under the Code all or a portion of such  dividends may be
(i) a  preference  item for  purposes of the  alternative  minimum  tax,  (ii) a
component  of the "ACE"  adjustment  for purposes of  determining  the amount of
corporate alternative minimum tax or (iii) a factor in determining the extent to
which a  shareholder's  Social  Security or  railroad  retirement  benefits  are
taxable. Moreover, the receipt of exempt-interest dividends from the Fund affect
the federal tax liability of certain foreign  corporations,  S Corporations  and
insurance  companies.  Furthermore,  under the Code,  interest  on  indebtedness
incurred or continued to purchase or carry portfolio  shares,  which interest is
deemed  to  relate  to  exempt-interest  dividends,  will not be  deductible  by
shareholders of the Fund for federal income tax purposes.

   The exemption of exempt-interest  dividend income from regular federal income
taxation does not necessarily result in similar exemptions for such income under
tax laws of state or local taxing  authorities.  In general,  states exempt from
state  income tax only that  portion  of any  exempt-interest  dividend  that is
derived from interest received by a regulated investment company on its holdings
of  obligations  issued  by  that  state  or  its  political   subdivisions  and
instrumentalities.

   To the extent that Municipal Bond Fund's  dividends are derived from interest
on its temporary taxable investments or from an excess of net short-term capital
gain over net  long-term  capital loss,  they are  considered  taxable  ordinary
income for federal  income tax purposes.  Such  dividends do not qualify for the
dividends-received  deduction for corporations.  Distributions by Municipal Bond
Fund, if any, of net long-term capital gains in excess of net short-term capital
losses from the sale of  securities  are taxable to  stockholders  as  long-term
capital gain  regardless  of the length of time the  stockholder  has owned Fund
shares. Furthermore, a loss realized by a stockholder on the redemption, sale or
exchange of shares of Municipal Bond Fund with respect to which  exempt-interest
dividends  have been paid will be disallowed to the extent of the amount of such
exempt-interest  dividends if such shares have been held by the  stockholder for
six months or less.
    
   Distributions  of net investment  income and realized net short-term  capital
gain by Corporate Bond, Limited Maturity Bond, U.S.  Government,  High Yield and
Cash Funds are taxable to stockholders  as ordinary  income whether  received in
cash or  reinvested  in additional  shares.  Distributions  of net capital gain,
whether received in cash or reinvested in Fund shares, will generally be taxable
to  shareholders  as either "20% Gain" or "28% Gain",  depending upon the Fund's
holding period for the assets sold.  "20% Gains" arise from sales of assets held
by a Fund for more than 18 months and are subject to a maximum tax

================================================================================
rate of 20%; "28% Gains" arise from sales of assets held by a Fund for more than
one year but no more than 18 months  and are  subject  to a maximum  tax rate of
28%.  Net  capital  gains from assets held for one year or less will be taxed as
ordinary  income.  Distributions  will be subject to these  capital  gains rates
regardless  of how long  shareholder  has held  Fund  shares.  Since  Cash  Fund
normally will not invest in securities  having a maturity of more than one year,
it should not realize any long-term capital gains or losses.
   
   At December 31, 1997, Corporate Bond, Limited Maturity Bond, U.S. Government,
High Yield and Municipal Bond Funds, respectively,  had accumulated net realized
losses on sales of investments in the following amounts: $__________,  $_______,
$________, $______ and $__________.
    
   Certain  dividends  declared in  October,  November or December of a calendar
year are taxable to  stockholders as though received on December 31 of that year
if paid to stockholders during January of the following calendar year.

   Advice as to each year's taxable dividends and distributions,  if applicable,
will be mailed on or  before  January  31 of the  following  year.  Stockholders
should  consult their tax adviser to determine the effect of federal,  state and
local tax consequences to them from an investment in the Funds.

   The Funds are required by law to withhold 31 percent of taxable dividends and
distributions (including redemption proceeds) to stockholders who do not furnish
their correct taxpayer  identification  numbers, or are otherwise subject to the
backup withholding provisions of the Internal Revenue Code.

FOREIGN TAXES

   Investment  income and gains received from sources  within foreign  countries
may be subject to foreign  income and other taxes.  In this regard,  withholding
tax rates in countries  with which the United  States does not have a tax treaty
are often as high as 30 percent or more.  The United States has entered into tax
treaties  with many  foreign  countries  which  entitle  certain  investors to a
reduced tax rate  (generally ten to fifteen  percent) or to exemptions from tax.
If  applicable,  the Funds will  operate so as to qualify  for such  reduced tax
rates or tax exemptions whenever possible. The payment of such taxes will reduce
the amount of dividends and distributions  paid to the Funds'  stockholders.  So
long as a Fund qualifies as a regulated investment company, certain distribution
requirements are satisfied, and more than 50% of such Fund's assets at the close
of the taxable year consists of securities of foreign corporation,  the Fund may
elect,  subject to  limitation,  to pass  through its foreign tax credits to its
stockholders.

DETERMINATION OF NET ASSET VALUE

   The net asset value per share of each Fund is  determined  as of the close of
regular  trading hours on the New York Stock Exchange  (normally 3 p.m.  Central
time) on each day that the Exchange is open for trading.  The  determination  is
made by dividing  the value of the  portfolio  securities  of each Fund plus any
cash or other assets, less all liabilities,  by the number of shares outstanding
of the Fund.

   Securities which are listed or traded on a national  securities  exchange are
valued at the last sale price.  If there are no sales on a particular  day, then
the securities are valued at the last bid price.  All other securities for which
market  quotations  are  readily  available  are valued on the basis of the last
current bid price.  If there is no bid price or if the bid price is deemed to be
unsatisfactory by the Board of Directors or by the Investment Manager,  then the
securities  are  valued in good faith by such  method as the Board of  Directors
determines will reflect the fair market value.
   
   Valuations of Municipal  Bond Fund's  municipal  securities are supplied by a
pricing service approved by the Board of Directors.  Valuations furnished by the
pricing service are based upon appraisals from recognized  municipal  securities
dealers derived from information  concerning market transactions and quotations.
Securities  for which market  quotations  are not readily  available  (which are
expected  to  constitute  the  majority  of  Municipal  Bond  Fund's   portfolio
securities) are valued by the pricing service considering such factors as yields
or prices of  municipal  bonds of  comparable  quality,  type of issue,  coupon,
maturity and rating,  indications  as to value from dealers,  and general market
conditions.  The Fund's officers,  under the general supervision of its Board of
Directors, will regularly review procedures used by, and valuations provided by,
the pricing service.
    
   U.S.  Government Fund values U.S.  Government  securities at market value, if
available.  If  market  quotations  are  not  available,  the  Fund  will  value
securities,  other than securities with 60 days or less to maturity as discussed
below, at fair prices based on market quotations for securities of similar type,
yield, quality and duration.
   
   The  securities  held by Cash Fund are  valued on the basis of the  amortized
cost valuation  technique which does not take into account  unrealized  gains or
losses. The amortized cost valuation technique involves valuing an instrument at
its cost and  thereafter  assuming a constant  amortization  to  maturity of any
discount or premium,  regardless of the impact of fluctuating  interest rates on
the market value of the instrument.  A similar procedure may be used for valuing
securities  held by the U.S.  Government and Municipal Bond Funds having 60 days
or less  remaining to  maturity,  with the value of the security on the 61st day
being used rather than cost.

================================================================================
   Because the expenses of distribution are borne by Class A shares of Corporate
Bond,  Limited  Maturity Bond,  U.S.  Government,  High Yield and Municipal Bond
Funds  through a  front-end  sales  charge  and by Class B shares of such  Funds
through an ongoing distribution fee, the expenses  attributable to each class of
shares will differ, resulting in different net asset values. The net asset value
of Class B shares  will  generally  be lower than the net asset value of Class A
shares as a result of the  distribution  fee  charged  to Class B shares.  It is
expected,  however,  that the net asset  value per share  will tend to  converge
immediately after the payment of dividends which will differ in amount for Class
A and B  shares  by  approximately  the  amount  of the  different  distribution
expenses attributable to Class A and B shares.

PERFORMANCE

   The Funds may, from time to time, include  performance data in advertisements
or reports to stockholders or prospective  investors.  Such performance data may
include quotations of "yield" for each of the Funds,  "effective yield" for Cash
Fund,  "taxable-equivalent  yield" for Municipal  Bond Fund and "average  annual
total return" and "aggregate total return" for Corporate Bond,  Limited Maturity
Bond, U.S. Government, High Yield and Municipal Bond Funds.
    
   For Cash Fund,  yield is calculated  by measuring  the income  generated by a
hypothetical investment in the Fund over a seven-day period. This income is then
annualized  by assuming that the amount of income  generated  over the seven-day
period is generated each week over a 52-week period and is shown as a percentage
of the investment.

   Cash  Fund's   effective  yield  will  be  calculated   similarly  but,  when
annualized,  income  earned  by an  investment  in the  Fund  is  assumed  to be
reinvested.  The effective  yield will be slightly higher than the yield because
of the compounding effect of this assumed reinvestment.
   
   With respect to Corporate Bond, Limited Maturity Bond, U.S. Government,  High
Yield and  Municipal  Bond Funds,  yield is based on the  investment  income per
share  earned  during  a  particular  30-day  period  (including  dividends  and
interest),  less expenses accrued during the period ("net  investment  income"),
and will be computed by dividing net investment  income per share by the maximum
public offering price per share on the last day of the period.

   Municipal  Bond Fund's  taxable-equivalent  yield begins with that portion of
the Fund's yield which is tax-exempt  (determined using the same general formula
used to calculate yield),  which is then adjusted by an amount necessary to give
the taxable  yield  equivalent  to the  tax-exempt  yield at a stated income tax
rate,  and added to that  portion  of the  Fund's  yield,  if any,  which is not
tax-exempt.

   Average  annual total return will be expressed in terms of the average annual
compounded  rate of return  of a  hypothetical  investment  in  Corporate  Bond,
Limited Maturity Bond, U.S.  Government,  High Yield or Municipal Bond Fund over
periods of one,  five and ten years (up to the life of the Fund).  Such  average
annual total return  figures  will  reflect the  deduction of the maximum  sales
charge and a  proportional  share of Fund expenses on an annual basis,  and will
assume that all dividends and distributions are reinvested when paid.

   Aggregate  total  return  will be  calculated  for any  specified  period  by
assuming a hypothetical  investment in Corporate  Bond,  Limited  Maturity Bond,
U.S.  Government,  High  Yield  or  Municipal  Bond  Fund  on  the  date  of the
commencement of the period and assuming that all dividends and distributions are
reinvested  when  paid.  The  net  increase  or  decrease  in the  value  of the
investment  over the period will be divided by its beginning  value to arrive at
aggregate total return.

   In addition,  total  return may also be  calculated  for several  consecutive
one-year  periods,  expressing  the total  return as a  percentage  increase  or
decrease  in the value of the  investment  for each year  relative to the ending
value for the  previous  year.  Corporate  Bond,  Limited  Maturity  Bond,  U.S.
Government,  High  Yield and  Municipal  Bond  Funds may from time to time quote
total return that does not reflect  deduction of any  applicable  sales  charge,
which charges, if reflected, would reduce the total return quoted.
    
   Quotations of  performance  reflect only the  performance  of a  hypothetical
investment in a Fund during the particular time period on which the calculations
are based.  Such  quotations  for the Funds will vary based on changes in market
conditions  and the level of the Fund's  expenses,  and no reported  performance
figure should be considered an indication of  performance  which may be expected
in the future.
   
   In  connection  with  communicating  performance  to current  or  prospective
stockholders,  the Funds also may compare  these figures to the  performance  of
other mutual  funds  tracked by mutual fund rating  services or other  unmanaged
indexes which may assume  reinvestment of dividends but generally do not reflect
deductions for administrative and management costs and expenses. Corporate Bond,
Limited Maturity Bond, U.S. Government, High Yield and Municipal Bond Funds will
include performance data for both Class A and Class B shares of the Funds in any
advertisement or report including performance data of the Fund.
    
   For a more detailed description of the methods used to calculate performance,
see the Funds' Statement of Additional Information.

STOCKHOLDER SERVICES
   
ACCUMULATION PLAN

   An investor in Corporate Bond, Limited Maturity Bond, U.S.  Government,  High
Yield or Municipal Bond Fund may choose to begin a voluntary  Accumulation Plan.
This allows for an initial investment of $100 minimum and subsequent investments
of $20 minimum at any time. An Accumulation  Plan involves no obligation to make
periodic investments and is terminable at will.
    
   Payments  are made by sending a check to the  Distributor  who  (acting as an
agent for the dealer) will purchase whole and  fractional  Fund shares as of the
close of business  on such day as the payment is  received.  The  investor  will
receive a confirmation and statement after each investment. Investors may choose
to use  "Secur-O-Matic"  (automatic  bank  draft) to make their Fund  purchases.
There is no additional charge for choosing to use Secur-O-Matic.  An application
may be obtained by writing Security Distributors,  Inc., 700 SW Harrison Street,
Topeka,  Kansas  66636-0001  or by calling  (785)  431-3127  or (800)  888-2461,
extension 3127.

SYSTEMATIC WITHDRAWAL PROGRAM

   Stockholders  who  wish  to  receive  regular  payments  of $25 or  more  may
establish a Systematic Withdrawal Program.  Liquidation in this manner will only
be  allowed  if  shares  with a  current  offering  price of  $5,000 or more are
deposited  with  the  Investment  Manager,  which  will  act as  agent  for  the
stockholder under the program.  Payments are available on a monthly,  quarterly,
semiannual  or annual  basis.  Shares are  liquidated  at net asset  value.  The
stockholder will receive a confirmation following each transaction.  The program
may be terminated on written notice,  or it will terminate  automatically if all
shares are liquidated or withdrawn from the account.

   A stockholder may establish a Systematic  Withdrawal  Program with respect to
Class B shares  without the  imposition of any  applicable  contingent  deferred
sales charge,  provided  that such  withdrawals  do not in any 12-month  period,
beginning on the date the Program is established, exceed 10 percent of the value
of the account on that date ("Free  Systematic  Withdrawals").  Free  Systematic
Withdrawals are not available if a Program  established  with respect to Class B
shares  provides  for  withdrawals  in excess of 10  percent of the value of the
account in any  Program  year and,  as a result,  all  withdrawals  under such a
Program would be subject to any  applicable  contingent  deferred  sales charge.
Free  Systematic  Withdrawals  will be made first by redeeming those shares that
are not subject to the  contingent  deferred  sales charge and then by redeeming
shares held the longest.  The contingent  deferred sales charge  applicable to a
redemption of Class B shares  requested  while Free  Systematic  Withdrawals are
being made will be  calculated  as described  under  "Calculation  and Waiver of
Contingent Deferred Sales Charges," page 25. A Systematic Withdrawal form may be
obtained from the Funds.

EXCHANGE PRIVILEGE

   Stockholders who own shares of the Funds may exchange those shares for shares
of another of the Funds, or for shares of the other mutual funds  distributed by
the Distributor,  which currently  include  Security Growth and Income,  Equity,
Global, Asset Allocation, Social Awareness, Value, Ultra, Emerging Markets Total
Return,  Global Asset  Allocation and Global High Yield Funds.  Exchanges may be
made only in those  states where shares of the fund into which an exchange is to
be made are qualified  for sale. No service fee is presently  imposed on such an
exchange.  Class A and Class B shares of the Funds may be exchanged  for Class A
and Class B shares, respectively, of another fund distributed by the Distributor
or for  shares  of Cash  Fund,  which  offers a  single  class  of  shares.  Any
applicable  contingent deferred sales charge will be calculated from the date of
the initial purchase without regard to the time shares were held in Cash Fund.

   For tax  purposes,  an  exchange  is a sale of shares  which may  result in a
taxable gain or loss. Special rules may apply to determine the amount of gain or
loss on an exchange occurring within ninety days after the exchanged shares were
acquired.
   
   Exchanges of Class A shares from Corporate Bond,  Limited Maturity Bond, U.S.
Government,  High Yield,  Municipal Bond, Emerging Markets Total Return,  Global
Asset Allocation and Global High Yield Funds are made at net asset value without
a front-end  sales charge if (1) the shares have been owned for not less than 90
consecutive days prior to the exchange, (2) the shares were acquired pursuant to
a prior  exchange  from a  Security  Fund which  assessed a sales  charge on the
original  purchase,  or  (3)  the  shares  were  acquired  as a  result  of  the
reinvestment of dividends or capital gains  distributions.  Exchanges of Class A
shares from Corporate Bond, Limited Maturity Bond, U.S. Government,  High Yield,
Municipal  Bond,  Emerging  Markets Total Return,  Global Asset  Allocation  and
Global High Yield Funds, other than those described above, are made at net asset
value plus the sales charge  described in the  prospectus of the other  Security
Fund being acquired,  less the sales charge paid on the shares of these Funds at
the time of original purchase.
    
   Because Cash Fund does not impose a sales charge or  commission in connection
with sales of its shares,  any  exchange of Cash Fund  shares  acquired  through
direct purchase or reinvestment of dividends will be based on the respective net
asset values of the shares  involved and a sales charge will be imposed equal to
the sales charge that would

be charged such stockholder if he or she were purchasing for cash.

   Stockholders  should contact the Fund before  requesting an exchange in order
to  ascertain  whether  any sales  charges  are  applicable  to the shares to be
exchanged.  In effecting the exchanges of Fund shares,  the  Investment  Manager
will first cause to be exchanged  those shares which would not be subject to any
sales charges.

   Exchanges   are  made  upon   receipt  of  a  properly   completed   Exchange
Authorization form. This privilege may be changed or discontinued at any time at
the  discretion  of  the  management  of the  Funds  upon  60  days'  notice  to
stockholders.  A current  prospectus  of the fund into which an exchange is made
will be given to each stockholder exercising this privilege.

EXCHANGE BY TELEPHONE

   To  exchange  shares  by  telephone,   a  stockholder  must  hold  shares  in
non-certificate  form and must  either have  completed  the  Telephone  Exchange
section of the application or a Telephone Transfer  Authorization form which may
be obtained from the Investment Manager. Once authorization has been received by
the  Investment  Manager,  a  stockholder  may  exchange  shares by telephone by
calling  the  Funds at (800)  888-2461,  extension  3127,  on  weekdays  (except
holidays)  between the hours of 7:00 a.m. and 6:00 p.m.  Central time.  Exchange
requests  received by telephone  after the close of the New York Stock  Exchange
(normally  3 p.m.  Central  time)  will be treated  as if  received  on the next
business day.

   A stockholder who authorizes  telephone  exchanges  authorizes the Investment
Manager to act upon the  instructions  of any person by  telephone  to  exchange
shares between any identically  registered accounts with the Funds listed above.
The Investment  Manager has established  procedures to confirm that instructions
communicated  by telephone  are genuine and will be liable for any losses due to
fraudulent  or  unauthorized  instructions  if  it  fails  to  comply  with  its
procedures.   The  Investment  Manager's  procedures  require  that  any  person
requesting an exchange by telephone provide the account  registration and number
and the owner's tax identification number and such instructions must be received
on a recorded line. Neither the Fund, the Investment Manager nor the Distributor
will be liable  for any loss,  liability,  cost or  expense  arising  out of any
request,  including any  fraudulent  request,  provided the  Investment  Manager
complied with its  procedures.  Thus, a  stockholder  who  authorizes  telephone
exchanges may bear the risk of loss from a fraudulent or unauthorized request.

   In periods of severe market or economic conditions, the telephone exchange of
shares may be difficult to implement and  stockholders  should make exchanges by
writing to Security  Distributors,  Inc., 700 Harrison  Street,  Topeka,  Kansas
66636-0001.  The telephone  exchange privilege may be changed or discontinued at
any time at the discretion of the management of the Funds.

RETIREMENT PLANS

   The Funds have  available  tax-qualified  retirement  plans for  individuals,
prototype  plans for the  self-employed,  pension and profit  sharing  plans for
corporations  and custodial  accounts for employees of public school systems and
organizations  meeting the  requirements  of Section  501(c)(3)  of the Internal
Revenue Code.  Further  information  concerning  these plans is contained in the
Funds' Statement of Additional Information.

GENERAL INFORMATION

ORGANIZATION
   
   The Articles of  Incorporation of Income and Municipal Bond Funds provide for
the issuance of an  indefinite  number of shares of capital stock in one or more
classes or series,  and the Articles of  Incorporation  of Cash Fund provide for
the issuance of an  indefinite  number of shares of capital stock in one or more
series.

   Income Fund has authorized  capital stock of $1.00 par value.  Its shares are
currently  issued in seven series,  Corporate Bond Fund,  Limited  Maturity Bond
Fund, U.S. Government Fund, High Yield Fund, Emerging Markets Total Return Fund,
Global  Asset  Allocation  Fund and Global High Yield  Fund.  The shares of each
series  represent a pro rata beneficial  interest in that series' net assets and
in the  earnings  and  profits or losses  derived  from the  investment  of such
assets.

   Municipal  Bond and Cash Funds  have  authorized  capital  stock of $0.10 par
value per share.
    
   Each of the Funds (except Cash Fund)  currently  issues two classes of shares
which  participate  proportionately  based on their relative net asset values in
dividends and distributions and have equal voting,  liquidation and other rights
except that (i) expenses  related to the distribution of each class of shares or
other  expenses that the Board of Directors may designate as class expenses from
time to time,  are borne  solely by each  class;  (ii) each  class of shares has
exclusive voting rights with respect to any  Distribution  Plan adopted for that
class; (iii) each class has different exchange  privileges;  and (iv) each class
has a different designation.

   When  issued  and  paid  for,  each  Fund's  shares  will be  fully  paid and
nonassessable  by the Funds.  Shares may be exchanged  as described  above under
"Exchange Privilege," but will have no other preference, conversion, exchange or
preemptive rights.  Shares are transferable,  redeemable and assignable and have
cumulative voting privileges for the election of directors.

   On certain  matters,  such as the election of  directors,  all shares of each
series of Income Fund vote  together,  with each share having one vote. On other
matters affecting a

particular series,  such as the Investment  Advisory Contract or the fundamental
investment  policies,  only  shares of that series are  entitled to vote,  and a
majority  vote of the shares of that  series is  required  for  approval  of the
proposal.

   The Funds do not generally hold annual meetings of  stockholders  and will do
so only when required by law.  Stockholders  may remove directors from office by
votes  cast in person or by proxy at a meeting of  stockholders.  Such a meeting
will be called at the  written  request of the holders of 10 percent of a Fund's

PROSPECTUS                                                            APPENDIX A
================================================================================
APPENDIX A

DESCRIPTION OF SHORT-TERM INSTRUMENTS

   The  types of  instruments  that  will  form the  major  part of Cash  Fund's
investments are described below:

   U.S.  GOVERNMENT  SECURITIES.  Federal agency securities are debt obligations
which principally result from lending programs of the U.S.  Government.  Housing
and agriculture have traditionally  been the principal  beneficiaries of federal
credit  programs,  and agencies  involved in providing credit to agriculture and
housing account for the bulk of the outstanding agency securities.

   Some U.S.  Government  securities,  such as  Treasury  bills and  bonds,  are
supported  by the full  faith  and  credit  of the  U.S.  Treasury;  others  are
supported by the right of the issuer to borrow from the Treasury;  others,  such
as those of the Federal  National  Mortgage  Association,  are  supported by the
discretionary  authority  of  the  U.S.  Government  to  purchase  the  agency's
obligations;   still  others  such  as  those  of  the  Student  Loan  Marketing
Association, are supported only by the credit of the instrumentality.

   U.S.  Treasury bills are issued with maturities of any period up to one year.
Three-month  bills are currently  offered by the Treasury on a 13-week cycle and
are auctioned  each week by the  Treasury.  Bills are issued in bearer form only
and are sold only on a discount basis,  and the difference  between the purchase
price  and the  maturity  value  (or the  resale  price if they are sold  before
maturity) constitutes the interest income for the investor.

   CERTIFICATES  OF DEPOSIT.  A certificate  of deposit is a negotiable  receipt
issued by a bank or savings and loan  association in exchange for the deposit of
funds. The issuer agrees to pay the amount deposited plus interest to the bearer
of the receipt on the date specified on the certificate.

   COMMERCIAL  PAPER.   Commercial  paper  is  generally  defined  as  unsecured
short-term  notes  issued in bearer form by large  well-known  corporations  and
finance companies.  Maturities on commercial paper range from a few days to nine
months. Commercial paper is also sold on a discount basis.

   BANKER'S   ACCEPTANCES.   A  banker's  acceptance  generally  arises  from  a
short-term credit  arrangement  designed to enable businesses to obtain funds to
finance commercial transactions.  Generally, an acceptance is a time draft drawn
on a bank by an exporter  or an  importer to obtain a stated  amount of funds to
pay for specific  merchandise.  The draft is then  "accepted" by a bank that, in
effect,  unconditionally  guarantees to pay the face value of the  instrument on
its maturity date.

DESCRIPTION OF COMMERCIAL PAPER RATINGS

   A Prime rating is the highest  commercial  paper  rating  assigned by Moody's
Investors Service, Inc. ("Moody's"). Issuers rated Prime are further referred to
by use of numbers 1, 2 and 3 to denote  relative  strength  within this  highest
classification. Among the factors considered by Moody's in assigning ratings are
the  following:  (1)  evaluation of the  management of the issuer;  (2) economic
evaluation  of  the  issuer's   industry  or  industries  and  an  appraisal  of
speculative type risks which may be inherent in certain areas; (3) evaluation of
the issuer's  products in relation to competition and customer  acceptance;  (4)
liquidity;  (5) amount and quality of long-term debt; (6) trend of earnings over
a period of ten  years;  (7)  financial  strength  of a parent  company  and the
relationships  which exist with the issuer; and (8) recognition by management of
obligations  which may be  present  or may arise as a result of public  interest
questions and preparations to meet such obligations.

   Commercial paper rated "A" by Standard & Poor's  Corporation  ("S&P") has the
highest  rating and is  regarded  as having  the  greatest  capacity  for timely
payment.  Commercial  paper rated A-1 by S&P has the following  characteristics:
(1)  liquidity  ratios are  adequate to meet cash  requirements;  (2)  long-term
senior  debt is rated "A" or  better;  (3) the issuer has access to at least two
additional  channels  of  borrowing;  (4) basic  earnings  and cash flow have an
upward trend with allowance made for unusual circumstances;  (5) typically,  the
issuer's  industry  is well  established  and the issuer  has a strong  position
within the  industry;  and (6) the  reliability  and quality of  management  are
unquestioned.  Relative  strength  or weakness  of the above  factors  determine
whether the issuer's commercial paper is rated A-1, A-2 or A-3.

DESCRIPTION OF CORPORATE BOND RATINGS

MOODY'S INVESTORS SERVICE, INC.

   Aaa -- Bonds which are rated Aaa are judged to be of the best  quality.  They
carry the smallest  degree of investment  risk and are generally  referred to as
"gilt-edge."  Interest  payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change,  such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

   Aa -- Bonds  which  are  rated Aa are  judged  to be of high  quality  by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds.  They are rated lower than the best bonds  because  margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present

================================================================================
which make the long-term risks appear somewhat larger than in Aaa securities.

   A -- Bonds which are rated A possess many favorable investment attributes and
are to be considered as upper medium grade obligations.  Factors giving security
to principal and interest are considered  adequate,  but elements may be present
which suggest a susceptibility to impairment sometime in the future.

   Baa -- Bonds which are rated Baa are considered as medium grade  obligations,
i.e., they are neither highly  protected nor poorly secured.  Interest  payments
and principal  security appear adequate for the present,  but certain protective
elements may be lacking or may be  characteristically  unreliable over any great
length of time. Such bonds lack outstanding  investment  characteristics  and in
fact have speculative characteristics as well.

   Ba -- Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered  as well assured.  Often the  protection of interest
and  principal  payments may be very  moderate and thereby not well  safeguarded
during  both  good  and bad  times  over the  future.  Uncertainty  of  position
characterizes bonds in this class.

   B -- Bonds which are rated B generally lack  characteristics of the desirable
investment.  Assurance of interest and principal  payments or of  maintenance of
other terms of the contract over any long period of time may be small.

   Caa -- Bonds which are rated Caa are of poor standing.  Such issues may be in
default or there may be present  elements of danger with respect to principal or
interest.

   Ca -- Bonds which are rated Ca represent obligations which are speculative in
a  high  degree.  Such  issues  are  often  in  default  or  have  other  market
shortcomings.

   C -- Bonds which are rated C are the lowest rated class of bonds,  and issues
so rated can be regarded as having  extremely  poor  prospects of ever attaining
any real investment standing.

   NOTE:  Moody's applies numerical  modifiers 1, 2 and 3 in each generic rating
classification  from Aa through B. The  modifier 1 indicates  that the  security
ranks in the higher end of its generic rating category. The modifier 2 indicates
a mid-range ranking,  and modifier 3 indicates that the issue ranks in the lower
end of its generic rating category.

STANDARD & POOR'S CORPORATION

   AAA -- Bonds rated AAA have the highest rating  assigned by Standard & Poor's
to a debt obligation.  Capacity to pay interest and repay principal is extremely
strong.

   AA -- Bonds rated AA have a very strong  capacity to pay  interest  and repay
principal and differ from the highest rated issues only in small degree.

   A -- Bonds rated A have a strong capacity to pay interest and repay principal
although they are somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than bonds in higher rated categories.

   BBB -- Bonds rated BBB are  regarded  as having an  adequate  capacity to pay
interest and repay principal.  Whereas they normally exhibit adequate protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened  capacity to pay interest and repay  principal  for
bonds in this category than for bonds in higher rated categories.

   BB, B, CCC, CC -- Bonds rated BB, B, CCC and CC are regarded,  on balance, as
predominantly  speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance  with the terms of  obligations.  BB indicates
the lowest degree of speculation and CC the highest degree of speculation. While
such bonds will likely have some quality and protective  characteristics,  these
are  outweighed  by large  uncertainties  or major  risk  exposures  to  adverse
conditions.

   C -- The rating C is reserved  for income bonds in which no interest is being
paid.

   D -- Debt rated D is in default and payment of interest  and/or  repayment of
principal is in arrears.

   NOTE:  Standard  &  Poor's  ratings  from  AA to CCC may be  modified  by the
addition  of a plus or minus  sign to show  relative  standing  within the major
categories.

APPENDIX B

DESCRIPTION OF MUNICIPAL BOND RATINGS
   
   The following are summaries of the ratings used by Moody's, Standard & Poor's
and Fitch's applicable to permitted investments of Municipal Bond Fund:
    
MOODY'S INVESTORS SERVICE, INC.*

   Aaa --  Municipal  bonds  which are  rated  Aaa are  judged to be of the best
quality.  They carry the smallest  degree of  investment  risk and are generally
referred to as "gilt-edge."  Interest payments are protected by a large or by an
exceptionally   stable  margin  and  principal  is  secure.  While  the  various
protective  elements are likely to change, such changes as can be visualized are
most unlikely to impair the fundamentally strong position of such issues.

   Aa -- Municipal  bonds which are rated Aa are judged to be of high quality by
all  standards.  Together  with the Aaa group they  comprise  what are generally
known as high grade  bonds.  They are rated  lower  than the best bonds  because
margins of protection may not be as large as in Aaa securities or fluctuation of
protective  elements may be of greater  amplitude or there may be other elements
present  which make the  long-term  risks  appear  somewhat  larger  than in Aaa
securities.

   A --  Municipal  bonds which are rated A possess  many  favorable  investment
attributes and are to be considered as upper medium grade  obligations.  Factors
giving security to principal and interest are considered adequate,  but elements
may be present which  suggest a  susceptibility  to  impairment  sometime in the
future.

   Baa -- Bonds which are rated Baa are considered as medium grade  obligations,
i.e., they are neither highly  protected nor poorly secured.  Interest  payments
and principal  security appear adequate for the present,  but certain protective
elements may be lacking or may be  characteristically  unreliable over any great
length of time. Such bonds lack outstanding  investment  characteristics  and in
fact have speculative characteristics as well.

   NOTE:  Moody's applies numerical  modifiers 1, 2 and 3 in each generic rating
classification  from  Aa  through  B in its  corporate  bond  ratings.  Although
Industrial Revenue Bonds and Environmental  Control Revenue Bonds are tax-exempt
issues,  they are included in the corporate bond rating  system.  The modifier 1
indicates  that the  security  ranks in the  higher  end of its  generic  rating
category. The modifier 2 indicates a mid-range ranking, and modifier 3 indicates
that the issue ranks in the lower end of its generic  rating  category.  Moody's
does not apply numerical  modifiers other than Aa1, A1 and Baa1 in its municipal
bond rating system,  which offer the maximum  security  within the Aa, A and Baa
groups, respectively.

STANDARD & POOR'S CORPORATION**

   AAA -- Municipal bonds rated AAA are highest grade obligations.  They possess
the ultimate degree of protection as to principal and interest.

   AA -- Municipal bonds rated AA also qualify as high grade obligations, and in
the majority of instances differ from AAA issues only in small degree.

   A -- Municipal  bonds rated A are regarded as upper medium  grade.  They have
considerable  investment strength but are not entirely free from adverse effects
of changes in economic and trade conditions. Interest and principal are regarded
as safe.

   BBB -- Bonds rated BBB are  regarded  as having an  adequate  capacity to pay
principal  and  interest.  Whereas they  normally  exhibit  adequate  protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened capacity to pay principal and interest for bonds in
this category than for bonds in the A category.

   NOTE:  Standard  &  Poor's  ratings  from  AA to CCC may be  modified  by the
addition  of a plus or minus  sign to show  relative  standing  within the major
categories.
   
FITCH INVESTORS SERVICE, INC.

   AAA -- Bonds  considered  to be  investment  grade and of the highest  credit
quality.  The obligor has an  exceptionally  strong  ability to pay interest and
repay  principal,  which is unlikely to be  affected by  reasonably  foreseeable
events.

   AA --  Bonds  considered  to be  investment  grade  and of very  high  credit
quality.  The  obligor's  ability to pay  interest  and repay  principal is very
strong,  although not quite as strong as bonds rated "AAA."  Because bonds rated
in the "AAA" and "AA" categories are not significantly vulnerable to foreseeable
future developments, short-term debt of these issuers is generally rated "F-1+".

   A -- Bonds considered to be investment grade and of high credit quality.  The
obligor's  ability to pay  interest  and repay  principal  is  considered  to be
strong, but may be more vulnerable to adverse changes in economic conditions and
circumstances than bonds with higher ratings.

   BBB -- Bonds  considered to be investment  grade and of  satisfactory  credit
quality. The obligor's ability to pay interest and repay principal is considered
to be  adequate.  Adverse  changes in  economic  conditions  and  circumstances,
however,  are more likely to have adverse  impact on these bonds,  and therefore
impair timely payment.  The likelihood that the ratings of these bonds will fall
below investment grade is higher than for bonds with higher ratings.

   NOTE:  Plus and minus  signs are used with a rating  symbol to  indicate  the
relative position of a credit within the rating category.  Plus and minus signs,
however, are not used in the "AAA" category.

RATINGS OF SHORT-TERM SECURITIES

MOODY'S INVESTORS SERVICE

   The following ratings apply to short-term municipal notes and loans:

   MIG 1 -- Loans bearing this  designation  are of the best  quality,  enjoying
strong  protection  from  established  cash  flows for their  servicing  or from
established and broadbased access to the market for refinancing, or both.

   MIG 2 -- Loans bearing this  designation  are of high quality with margins of
protection ample although not so large as in the preceding group.

   The following ratings apply to both commercial paper and municipal paper:

   PRIME-1  -- Issuers  receiving  this  rating  have a  superior  capacity  for
repayment of short-term promissory obligations.

   PRIME-2 -- Issuers receiving this rating have a strong capacity for repayment
of short-term promissory obligations.

STANDARD & POOR'S CORPORATION

   The following ratings apply to short-term municipal notes:

   AAA -- This is the highest  rating  assigned by S&P to a debt  obligation and
indicates an extremely strong capacity to repay principal and pay interest.

   AA -- Notes rated AA have a very strong  capacity to repay  principal and pay
interest and differ from AAA issues only in small degree.

   The following ratings apply both to commercial paper and municipal paper:

   A-1 -- This designation  indicates that the degree of safety regarding timely
payment is very strong.

   A-2 -- Capacity for timely payment on issues with this designation is strong.
However,  the  relative  degree of safety is not as  overwhelming  as for issues
designated A-1.
   
FITCH INVESTORS SERVICE

   The following ratings apply to commercial paper:

   F-1+ -- Exceptionally strong credit quality.  Issues assigned this rating are
regarded as having the strongest degree of assurance for timely payment.

   F-1 -- Very strong credit  quality.  Issues  assigned this rating  reflect an
assurance  of timely  payment  only  slightly  less in degree than issues  rated
"F-1+".

   F-2 -- Issues  assigned this rating have a  satisfactory  degree of assurance
for  timely  payment  but the  margin of  safety  is not as great as for  issues
assigned "F-1+" or "F-1".

 *Moody's Investors Service,  Inc. rates bonds of issuers which have $600,000 or
  more of  debt,  except  bonds  of  educational  institutions,  projects  under
  construction,  enterprises without established earnings records and situations
  where current financial data is unavailable.
    
**Standard & Poor's Corporation rates all governmental  bodies having $1,000,000
  or more of debt outstanding unless adequate information is not available.

APPENDIX C

REDUCED SALES CHARGES
CLASS A SHARES
   
   Initial  sales   charges  may  be  reduced  or  eliminated   for  persons  or
organizations  purchasing Class A shares of the Corporate Bond, Limited Maturity
Bond,  U.S.  Government,  High  Yield  and  Municipal  Bond  Funds  alone  or in
combination with Class A shares of certain other Security Funds.
    
   For  purposes of  qualifying  for reduced  sales  charges on  purchases  made
pursuant to Rights of Accumulation or a Statement of Intention (also referred to
as a "Letter of Intent"),  the term "Purchaser"  includes the following persons:
an individual;  an  individual,  his or her spouse and children under the age of
21; a trustee or other  fiduciary of a single  trust estate or single  fiduciary
account  established  for their  benefit;  an  organization  exempt from federal
income tax under  Section  501(c)(3) or (13) of the Internal  Revenue Code; or a
pension,  profit-sharing or other employee benefit plan whether or not qualified
under Section 401 of the Internal Revenue Code.

RIGHTS OF ACCUMULATION
   
   To reduce sales  charges on  purchases  of Class A shares of Corporate  Bond,
Limited  Maturity Bond,  U.S.  Government,  High Yield or Municipal Bond Fund, a
Purchaser  may combine all previous  purchases  of the Fund with a  contemplated
current purchase and receive the reduced  applicable front end sales charge. The
Distributor must be notified when a sale takes place which might qualify for the
reduced charge on the basis of previous purchases.

   Rights of accumulation also apply to purchases  representing a combination of
the Class A shares of Corporate Bond,  Limited  Maturity Bond, U.S.  Government,
High Yield, Municipal Bond, Growth and Income, Equity, Global, Asset Allocation,
Social  Awareness,  Value or Ultra Fund in those states where shares of the Fund
being purchased are qualified for sale.

STATEMENT OF INTENTION

   A Purchaser of Corporate Bond, Limited Maturity Bond, U.S.  Government,  High
Yield or Municipal Bond Fund may choose to sign a Statement of Intention  within
90 days after the first  purchase  to be included  thereunder,  which will cover
future  purchases of Class A shares of those  Funds,  Security  Equity,  Global,
Asset Allocation,  Social Awareness, Value, Growth and Income or Ultra Fund. The
amount of these future  purchases  shall be specified  and must be made within a
13-month  period (or  36-month  period for  purchases  of $1 million or more) to
become eligible for the reduced  front-end sales charge applicable to the actual
amount purchased under the statement.  Five percent (5%) of the amount specified
in the Statement of Intention  will be held in escrow shares until the Statement
is  completed  or  terminated.  These  shares may be redeemed by the Fund if the
Purchaser is required to pay additional sales charges. Any dividends paid by the
Fund will be payable with respect to escrow shares. The Purchaser bears the risk
that the escrow shares may decrease in value.
    
   A  Statement  of  Intention  may be  revised  during  the  13-month  (or,  if
applicable,  36-month)  period.  Additional shares received from reinvestment of
income  dividends  and capital  gains  distributions  are  included in the total
amount used to determine reduced sales charges.
   
REINSTATEMENT PRIVILEGE

   Stockholders  who redeem  their  Class A shares of  Corporate  Bond,  Limited
Maturity  Bond,  U.S.  Government,  High  Yield or  Municipal  Bond  Fund have a
one-time  privilege (1) to reinstate their accounts by purchasing shares without
a sales charge up to the dollar amount of the redemption proceeds; or (2) to the
extent the redeemed shares would have been eligible for the exchange  privilege,
to purchase shares of another of the Funds, Security Growth and Income,  Equity,
Global, Asset Allocation, or Ultra Fund, without a sales charge up to the dollar
amount of the redemption  proceeds.  To exercise this  privilege,  a stockholder
must provide  written  notice and the amount to be reinvested to the Fund within
30 days after the redemption request.
    
   The  reinstatement  or  exchange  will be made at the net  asset  value  next
determined after the reinvestment is received by the Fund.

GENERAL INFORMATION
   
   Security  Income  Fund,  Security  Municipal  Bond  Fund  (formerly  Security
Tax-Exempt  Fund)  and  Security  Cash  Fund,  which  were  organized  as Kansas
corporations on April 20, 1965, July 14, 1981 and March 21, 1980,  respectively,
are  registered  with the  Securities  and  Exchange  Commission  as  investment
companies.   The  name  of  Security  Municipal  Bond  Fund  (formerly  Security
Tax-Exempt Fund) was changed  effective May 1, 1998. Such  registration does not
involve  supervision by the Securities and Exchange Commission of the management
or  policies  of the  Funds.  The Funds  are  diversified,  open-end  management
investment  companies that,  upon the demand of the investor,  must redeem their
shares and pay the investor the current net asset value  thereof.  ( See "How to
Redeem Shares," page 45.)

   Each of the Corporate Bond Series  ("Corporate Bond Fund"),  Limited Maturity
Bond Series  ("Limited  Maturity  Bond Fund"),  U.S.  Government  Series  ("U.S.
Government  Fund") and High Yield Series ("High Yield Fund") of Security  Income
Fund, Municipal Bond Fund ("Municipal Bond Fund"), and Security Cash Fund ("Cash
Fund") (the "Funds") has its own  investment  objective  and policies  which are
described  below.  While there is no present  intention to do so, the investment
objective and policies of each Fund,  unless  otherwise noted, may be changed by
its Board of Directors  without the approval of stockholders.  Each of the Funds
is also  required  to operate  within  limitations  imposed  by its  fundamental
investment policies which may not be changed without stockholder approval. These
limitations are set forth below under "Investment Policy  Limitations," page 26.
An  investment  in one of the Funds does not  constitute  a complete  investment
program.
    
   The  value of the  shares  of each  Fund  fluctuates  with  the  value of the
portfolio  securities.  Each  Fund may  realize  losses  or gains  when it sells
portfolio  securities  and will  earn  income  to the  extent  that it  receives
dividends or interest from its  investments.  (See  "Dividends  and Taxes," page
51.)
   
   The shares of Corporate Bond,  Limited Maturity Bond, U.S.  Government,  High
Yield and Municipal Bond Funds are sold to the public at net asset value, plus a
sales commission which is divided between the principal  distributor and dealers
who sell the shares ("Class A shares"),  or at net asset value with a contingent
deferred  sales charge  ("Class B shares").  The shares of Cash Fund are sold to
the public at net asset value.  There is no sales charge or load when purchasing
shares of Cash Fund. (See "How to Purchase Shares," page 33.)

   The  Funds  receive  investment  advisory,  administrative,  accounting,  and
transfer agency services from Security Management Company,  LLC (the "Investment
Manager") for a fee. The Investment  Manager has  guaranteed  that the aggregate
annual expenses  (including the management  compensation but excluding brokerage
commissions,  interest,  taxes,  extraordinary expenses and Class B distribution
fees) shall not for Corporate Bond,  Limited Maturity Bond, U.S.  Government and
High Yield Funds  exceed any expense  limitation  imposed by any state and shall
not for Cash Fund  exceed 1% of the average net assets of the Fund for the year.
The Investment  Manager has also guaranteed  that the aggregate  annual expenses
(including  the  management   compensation   but  excluding   interest,   taxes,
extraordinary  expenses and Class A and Class B distribution fees) shall not for
Municipal  Bond Fund exceed 1% of the net assets of the Fund for the year.  (See
page 40 for a discussion of the Investment  Manager and the Investment  Advisory
Contract.)
    
   Each Fund will pay all its expenses not assumed by the Investment  Manager or
Security Distributors, Inc. (the "Distributor") including organization expenses;
directors'  fees;  fees of  custodian;  taxes and  governmental  fees;  interest
charges; any membership dues; brokerage  commissions;  expenses of preparing and
distributing  reports to stockholders;  costs of stockholder and other meetings;
and legal,  auditing and  accounting  expenses.  Each Fund will also pay for the
preparation  and  distribution  of the  prospectus to its  stockholders  and all
expenses in connection with its registration under the Investment Company Act of
1940  and  the  registration  of its  capital  stock  under  federal  and  state
securities  laws.  Each  Fund  will  pay  nonrecurring  expenses  as may  arise,
including litigation expenses affecting it.
   
   Under a  Distribution  Plan  adopted  with  respect  to the Class A shares of
Corporate Bond, Limited Maturity Bond, U.S. Government, High Yield and Municipal
Bond Funds pursuant to Rule 12b-1 under the Investment  Company Act of 1940 (the
"1940 Act"), these Funds are authorized to pay to the Distributor, an annual fee
of .25% of the average  daily net assets of the Class A shares of the  Corporate
Bond,  Limited  Maturity Bond,  U.S.  Government,  High Yield and Municipal Bond
Funds to finance various distribution-related  activities. (See "Security Income
and Municipal Bond Funds' Class A Distribution Plans," page 36.)

   Under  Distribution  Plans  adopted  with  respect  to the  Class B shares of
Corporate Bond, Limited Maturity Bond, U.S. Government, High Yield and Municipal
Bond Funds pursuant to Rule 12b-1 under the 1940 Act,

                                       1
<PAGE>
each Fund is authorized to pay to the Distributor, an annual fee of 1.00% of the
average  daily  net  assets of the  Class B Shares  of the  respective  Funds to
finance  various  distribution-related  activities.  (See "Class B  Distribution
Plan," page 35.)

   The Funds may utilize short-term trading to a limited extent in order to take
advantage  of  differentials  in bond yields  consistent  with their  respective
investment objectives.  The portfolio turnover rate for the Funds' Class A and B
shares for the fiscal year ended  December 31, 1997 was:  Corporate Bond - ___ ;
U.S.  Government - ___ %; Limited Maturity Bond - ___ %; High Yield Bond - ___ ;
and Municipal  Bond - ___ . The  portfolio  turnover rate for the Funds' Class A
and B shares of Corporate  Bond,  U.S.  Government,  Limited  Maturity  Bond and
Municipal Bond Funds for the fiscal year ended December 31, 1996, was: Corporate
Bond - 292%; U.S.  Government - 75%;  Limited Maturity Bond -105%; and Municipal
Bond - 54%. The annualized  portfolio turnover rate for the Class A and B shares
of High Yield Fund for the period August 5, 1996 (date of inception) to December
31, 1996 was 168%. Portfolio turnover is the percentage of the lower of security
sales or  purchases  to the  average  portfolio  value  and would be 100% if all
securities in the Fund were replaced within a period of one year.
    
INVESTMENT OBJECTIVES AND POLICIES OF THE FUNDS

SECURITY INCOME FUND

   Security  Income Fund ("Income Fund")  consists of seven  diversified  Series
(Corporate  Bond,  Limited  Maturity  Bond,  U.S.  Government,  High Yield,  MFR
Emerging  Markets Total Return,  MFR Global Asset Allocation and MFR Global High
Yield  (formerly  Global  Aggressive  Bond) Funds),  each of which  represents a
different  investment  objective and which has its own identified assets and net
asset values.  The investment  objectives of Corporate  Bond,  Limited  Maturity
Bond, U.S.  Government and High Yield Funds are each described below.  There are
risks  inherent in the  ownership  of any security and there can be no assurance
that  such  investment  objectives  will  be  achieved.  Some of the  risks  are
described below.

   Corporate Bond, Limited Maturity Bond and U.S. Government Funds will purchase
solely debt securities and will not invest in securities  which are not publicly
traded or marketable.  Short-term  obligations may be purchased in any amount as
the Investment  Manager deems  appropriate for defensive or liquidity  purposes.
Each Fund's portfolio may include a significant  amount of debt securities which
sell at  discounts  from  their  face  amount  as a  result  of  current  market
conditions.  For example,  debt securities with fixed-rate coupons are generally
sold at a discount  from their face  amount  during  periods of rising  interest
rates.

   Income Fund makes no representation  that the stated investment  objective of
any Series will be achieved.  Although  there is no present  intention to do so,
the  investment  objective of any Series of the Fund may be altered by the Board
of Directors without the approval of stockholders of the Series.

CORPORATE BOND FUND

   The investment  objective of the Corporate  Bond Fund is to conserve  capital
while generating interest income. In pursuing its investment objective, the Fund
will invest in a broad range of debt securities, including (i) securities issued
by U.S. and Canadian  corporations;  (ii) securities issued or guaranteed by the
U.S. Government or any of its agencies or instrumentalities,  including Treasury
bills, certificates of indebtedness, notes and bonds; (iii) securities issued or
guaranteed  by the  Dominion of Canada or  provinces  thereof;  (iv)  securities
issued by foreign governments, their agencies and instrumentalities, and foreign
corporations, provided that such securities are denominated in U.S. dollars; (v)
higher  yielding,  high  risk debt  securities  (commonly  referred  to as "junk
bonds");  (vi) certificates of deposit issued by a U.S. branch of a foreign bank
("Yankee CDs"); (vii) investment grade mortgage-backed  securities ("MBSs"); and
(viii) zero coupon securities.  Under normal circumstances,  at least 65% of the
Fund's total assets will be invested in corporate debt  securities  which at the
time of issuance have a maturity greater than one year.
   
   Corporate Bond Fund will invest  primarily in corporate debt securities rated
Baa or higher by Moody's Investors Service, Inc. ("Moody's") or BBB or higher by
Standard & Poor's Corporation ("S&P") at the time of purchase, or if unrated, of
equivalent  quality as determined by the Investment  Manager.  See Appendix A to
the Prospectus  for a description  of corporate  bond ratings.  Included in such
securities  may be convertible  bonds or bonds with warrants  attached which are
rated at least Baa or BBB at the time of purchase,  or if unrated, of equivalent
quality as determined by the Investment Manager. A "convertible bond" is a bond,
debenture or

                                       2
<PAGE>
preferred  share which may be exchanged by the owner for common stock or another
security,  usually  of the same  company,  in  accordance  with the terms of the
issue.  A "warrant"  confers  upon its holder the right to purchase an amount of
securities at a particular  time and price.  Securities  rated Baa by Moody's or
BBB by S&P have speculative  characteristics.  See "Investment  Methods and Risk
Factors" for a discussion of the risks associated with such securities.
    
   Corporate Bond Fund may invest up to 25% of its net assets in higher yielding
debt  securities in the lower rating (higher risk)  categories of the recognized
rating services (commonly referred to as "junk bonds").  Such securities include
securities  rated Ba or lower by Moody's or BB or lower by S&P and are  regarded
as  predominantly  speculative with respect to the ability of the issuer to meet
principal  and interest  payments.  The Fund will not invest in junk bonds which
are rated in default at the time of purchase.  See "Investment  Methods and Risk
Factors"  for a  discussion  of the  risks  associated  with  investing  in such
securities.

   The Fund may purchase  securities which are obligations of, or guaranteed by,
the  Dominion  of Canada or  provinces  thereof  and debt  securities  issued by
Canadian  corporations.  Canadian securities will not be purchased if subject to
the foreign interest equalization tax and unless payable in U.S. dollars.

   The Fund may invest in Yankee CDs which are certificates of deposit issued by
a U.S. branch of a foreign bank denominated in U.S. dollars and held in the U.S.
Yankee CDs are subject to somewhat  different  risks than are the obligations of
domestic banks.  The Fund also may invest in debt  securities  issued by foreign
governments,  their  agencies and  instrumentalities  and foreign  corporations,
provided  that such  securities  are  denominated  in U.S.  dollars.  The Fund's
investment in foreign securities, including Canadian securities, will not exceed
25% of the Fund's net assets.  See  "Investment  Methods and Risk Factors" for a
discussion of the risks  associated  with investing in foreign  securities.  The
Fund may also invest in zero coupon  securities  which are debt  securities that
pay no cash income but are sold at substantial  discounts from their face value.
Certain  zero coupon  securities  also provide for the  commencement  of regular
interest payments at a deferred date.

   The Fund may invest in investment grade  mortgage-backed  securities  (MBSs),
including  mortgage   pass-through   securities  and   collateralized   mortgage
obligations  (CMOs).  The  Fund  may  invest  up to  10% of its  net  assets  in
securities known as "inverse floating  obligations,"  "residual interest bonds,"
or  "interest-only"  (IO) or  "principal-only"  (PO) bonds, the market values of
which  generally  will be more volatile than the market values of most MBSs. The
Fund will hold less than 25% of its net assets in MBSs. For a discussion of MBSs
and the risks associated with such securities,  see "Investment Methods and Risk
Factors."

   Corporate  Bond Fund may purchase  securities  on a "when issued" or "delayed
delivery"  basis in  excess of  customary  settlement  periods  for the types of
security involved. For a discussion of such securities,  see "Investment Methods
and Risk Factors." It is anticipated  that  securities  invested in by this Fund
will be held by the Fund on an  average  from one and a half to three  years and
that the average weighted  maturity of the Fund's portfolio will range from 5 to
15 years under normal circumstances.

   Corporate  Bond Fund may  invest in  repurchase  agreements  on an  overnight
basis. See the discussion of repurchase agreements under "Investment Methods and
Risk  Factors." The Fund may borrow money from banks as a temporary  measure for
emergency purposes or to facilitate redemption requests.  Borrowing is discussed
in more detail under "Investment  Methods and Risk Factors." Pending  investment
in  securities  or to  meet  potential  redemptions,  the  Fund  may  invest  in
certificates  of deposit,  bank demand  accounts and high  quality  money market
instruments.

LIMITED MATURITY BOND FUND

   The investment  objective of the Limited Maturity Bond Fund is to seek a high
level  of  income  consistent  with  moderate  price  fluctuation  by  investing
primarily in short- and intermediate-term bonds. As used herein the term "short-
and  intermediate-term  bonds"  is used to  describe  any debt  security  with a
maturity of 15 years or less.  In pursuing its  investment  objective,  the Fund
will invest in a broad range of debt securities, including (i) securities issued
by U.S. and Canadian  corporations;  (ii) securities issued or guaranteed by the
U.S. Government or any of its agencies or instrumentalities,  including Treasury
bills, certificates of indebtedness, notes and bonds; (iii) securities issued or
guaranteed  by, the Dominion of Canada or  provinces  thereof;  (iv)  securities
issued by  foreign  governments,  their  agencies,  and  instrumentalities,  and
foreign  corporations,  provided that such  securities  are  denominated in U.S.
dollars; (v) higher yielding, high risk debt securities (commonly referred to as
"junk bonds"); (vi) certificates of deposit issued by a U.S. branch of a foreign
bank  ("Yankee  CDs");  (vii)   mortgage-backed   securities  ("MBSs");   (viii)
investment grade asset-backed securities; and (ix) zero coupon securities. High

                                       3
<PAGE>
yield  debt  securities,  Yankee  CDs,  MBSs  and  asset-backed  securities  are
described in further detail under  "Investment  Methods and Risk Factors." Under
normal  circumstances,  the Fund  will  invest  at least 65% of the value of its
total assets in short- and  intermediate-term  bonds. It is anticipated that the
Fund's dollar weighted  average  maturity will range from 2 to 10 years. It will
never exceed 10 years.

   Limited Maturity Bond Fund will invest primarily in debt securities rated Baa
or higher by  Moody's  or BBB or  higher by S&P at the time of  purchase,  or if
unrated,  of equivalent  quality as determined by the  Investment  Manager.  Baa
securities are considered to be "medium grade" obligations by Moody's and BBB is
the lowest classification which is still considered an "investment grade" rating
by S&P.  Included  in such  securities  may be  convertible  bonds or bonds with
warrants  attached  which are rated at least Baa or BBB at the time of purchase,
or if unrated,  of equivalent quality as determined by the Investment Manager. A
"convertible  bond"  is a  bond,  debenture  or  preferred  share  which  may be
exchanged,  by the owner, for common stock or another  security,  usually of the
same company,  in accordance  with the terms of the issue.  A "warrant"  confers
upon its holder the right to purchase an amount of  securities  at a  particular
time and  price.  Bonds  rated  Baa by  Moody's  or BBB by S&P have  speculative
characteristics  and may be more  susceptible than higher grade bonds to adverse
economic  conditions  or other  adverse  circumstances  which  may  result  in a
weakened capacity to make principal and interest payments. See Appendix A to the
Prospectus for a description of corporate bond ratings.

   The Fund may invest in higher  yielding  debt  securities in the lower rating
(higher risk) categories of the recognized rating services (commonly referred to
as "junk  bonds");  however,  the Fund will  never hold more than 25% of its net
assets in junk bonds.  This includes  securities rated Ba or lower by Moody's or
BB or lower by S&P and are regarded as predominantly speculative with respect to
the ability of the issuer to meet principal and interest payments. The Fund will
not invest in junk bonds which are in default at the time of purchase.  However,
the Investment  Manager will not rely principally on the ratings assigned by the
rating  services.  Because  the  Fund may  invest  in  lower  rated  or  unrated
securities of  comparable  quality,  the  achievement  of the Fund's  investment
objective may be more dependent on the Investment  Manager's own credit analysis
than would be true if investing in higher rated securities.

   The Fund may purchase  securities which are obligations of, or guaranteed by,
the  Dominion  of Canada or  provinces  thereof  and debt  securities  issued by
Canadian  corporations.  Canadian securities will not be purchased if subject to
the foreign interest equalization tax and unless payable in U.S. currency.

   The Fund may invest in Yankee CDs which are Certificates of Deposit issued by
a U.S.  branch of a foreign  bank  denominated  in U.S.  dollars and held in the
United States.  Yankee CDs are subject to somewhat  different risks than are the
obligations  of  domestic  banks.  The Fund may also invest up to 25% of its net
assets in debt  securities  issued by foreign  governments,  their  agencies and
instrumentalities,  and foreign corporations,  provided that such securities are
denominated  in U.S.  dollars.  The Fund's  investment  in  foreign  securities,
including  Canadian  securities  will not exceed  25% of the Fund's net  assets.
Investment in securities of foreign issuers  presents  certain risks,  including
future  political  and  economic  developments  and the possible  imposition  of
foreign  governmental  laws and  restrictions,  reduced  availability  of public
information  concerning  issuers,  and the fact  that  foreign  issuers  are not
generally  subject to  uniform  accounting,  auditing  and  financial  reporting
standards or to other regulatory practices and requirements  comparable to those
applicable to domestic issuers.

   The Fund may  invest in U.S.  Government  securities.  Some  U.S.  Government
securities,  such as Treasury  bills and bonds,  are supported by the full faith
and credit of the U.S. Treasury;  others,  such as those of the Federal National
Mortgage Association,  are supported by the discretionary  authority of the U.S.
Government to purchase the agency's  obligations;  still others such as those of
the Student Loan Marketing Association,  are supported only by the credit of the
instrumentality.  U.S.  Government  securities  include bills,  certificates  of
indebtedness,  notes  and  bonds  issued  by  the  Treasury  or by  agencies  or
instrumentalities  of the U.S.  Government.  The Fund  may also  invest  in zero
coupon securities which are debt securities that pay no cash income but are sold
at substantial  discounts from their face value.  Certain zero coupon securities
also provide for the  commencement  of regular  interest  payments at a deferred
date.

   Limited Maturity Bond Fund may acquire certain securities that are restricted
as to  disposition  under  the  federal  securities  laws,  provided  that  such
securities are eligible for resale to qualified institutional investors pursuant
to Rule 144A under the  Securities Act of 1933, and subject to the Fund's policy
that not more than 15% of the Fund's  total  assets will be invested in illiquid
assets. See "Investment  Methods and Risk Factors" for a discussion of Rule 144A
Securities.

                                       4
<PAGE>
   The Fund may invest in investment grade  mortgage-backed  securities  (MBSs),
including  mortgage   pass-through   securities  and   collateralized   mortgage
obligations  (CMOs).  The  Fund  may  invest  up to  10% of its  net  assets  in
securities known as "inverse floating  obligations,"  "residual interest bonds,"
or "interest-only"  (IO) and  "principal-only"  (PO) bonds, the market values of
which will  generally be more volatile than the market values of most MBSs.  The
Fund  will hold less  than 25% of its net  assets  in MBSs,  including  CMOs and
mortgage pass-through securities.

   The Fund may also invest in investment grade "asset-backed securities." These
include secured debt instruments backed by automobile loans,  credit card loans,
home equity loans,  manufactured  housing loans and other types of secured loans
providing the source of both principal and interest.

   Limited  Maturity  Bond Fund may purchase  securities  on a "when  issued" or
"delayed delivery" basis in excess of customary  settlement periods for the type
of security involved. Securities purchased on a when issued basis are subject to
market fluctuations and no interest or dividends accrue to the Fund prior to the
settlement date. The Fund will establish a segregated account with its custodian
bank in which  it will  maintain  cash or  liquid  securities  equal in value to
commitments for such when issued securities.

   Limited  Maturity  Bond  Fund  may  invest  in  repurchase  agreements  on an
overnight basis. See the discussion of repurchase  agreements under  "Investment
Methods and Risk  Factors."  The Fund may borrow money from banks as a temporary
measure for emergency purposes or to facilitate  redemption requests.  Borrowing
is discussed in more detail under "Investment Methods and Risk Factors." Pending
investment in securities or to meet potential  redemptions,  the Fund may invest
in certificates  of deposit,  bank demand accounts and high quality money market
instruments.

   From time to time,  Limited  Maturity Bond Fund may invest part or all of its
assets in commercial notes or money market instruments.

U.S. GOVERNMENT FUND

   The  investment  objective of the U.S.  Government  Fund is to provide a high
level of interest  income with  security of principal by investing  primarily in
U.S. Government  securities.  U.S. Government  securities are obligations of, or
guaranteed (as to principal and interest) by, the U.S. Government,  its agencies
(such as the Federal Housing  Administration  and Government  National  Mortgage
Association) or  instrumentalities  (such as Federal Home Loan Banks and Federal
Land Banks), and instruments fully  collateralized with such obligations such as
repurchase agreements. U.S. Government securities include bills, Certificates of
Indebtedness,  notes  and  bonds  issued  by  the  Treasury  or by  agencies  or
instrumentalities of the U.S. Government.  The Fund may, for defensive purposes,
temporarily  invest  part  or all of its  assets  in  money  market  instruments
including deposits and bankers acceptances in depository institutions insured by
the FDIC, and short-term U.S. Government and agency securities.

   Some U.S.  Government  securities,  such as  treasury  bills and  bonds,  are
supported  by the full  faith  and  credit  of the  U.S.  Treasury,  others  are
supported by the right of the issuer to borrow from the Treasury,  others,  such
as those of the Federal  National  Mortgage  Association,  are  supported by the
discretionary  authority  of  the  U.S.  Government  to  purchase  the  agency's
obligations;   still  others  such  as  those  of  the  Student  Loan  Marketing
Association,  are  supported  only by the credit of the  instrumentality.  Under
normal  circumstances,  the Fund  will  invest  at least 80% of the value of its
total assets in U.S. Government securities.

   U.S.  Government  Fund may invest in  repurchase  agreements  on an overnight
basis. See the discussion of repurchase agreements under "Investment Methods and
Risk  Factors." The Fund may borrow money from banks as a temporary  measure for
emergency purposes or to facilitate redemption requests.  Borrowing is discussed
in more detail under "Investment  Methods and Risk Factors." Pending  investment
in  securities  or to  meet  potential  redemptions,  the  Fund  may  invest  in
certificates  of deposit,  bank demand  accounts and high  quality  money market
instruments.

   From  time to time the  portfolio  of the U.S.  Government  Fund may  consist
primarily of Government National Mortgage Association (GNMA) certificates.  GNMA
certificates are  mortgage-backed  securities  representing  part ownership of a
pool of mortgage loans. These loans, issued by lenders such as mortgage bankers,
commercial  banks and savings and loan  associations,  are either  issued by the
Federal Housing Administration or guaranteed by the Veterans  Administration.  A
"pool" or group of such  mortgages is  assembled  and,  after being  approved by
GNMA, is offered to investors through securities dealers. Once approved by GNMA,
the timely  payment of interest and  principal on each mortgage is guaranteed by
GNMA and backed by the full faith and credit of the U.S.

                                       5
<PAGE>
Government.  GNMA certificates  differ from bonds in that principal is paid back
monthly by the borrower over the term of the loan rather than returned in a lump
sum at maturity.  GNMA certificates are called "pass through" securities because
both interest and principal payments (including  prepayments) are passed through
to the holder of the certificate.

   The Fund may invest in other  mortgage-backed  securities (MBSs) as discussed
under  "Investment  Methods and Risk Factors -  Mortgage-Backed  Securities  and
Collateralized  Mortgage  Obligations" in the  Prospectus.  MBSs include certain
securities  issued by the United  States  government  or one of its  agencies or
instrumentalities,  such as GNMAs, or securities issued by private issuers.  The
Fund may not  invest  more  than 20% of the  value of its  total  assets in MBSs
issued by private  issuers.  The Fund may also invest in zero coupon  securities
which are debt  securities  that pay no cash income but are sold at  substantial
discounts from their face value. Certain zero coupon securities also provide for
the commencement of regular interest payments at a deferred date.

   The Fund will  attempt  to  maximize  the return on its  portfolio  by taking
advantage of market developments and yield disparities, which may include use of
the following strategies:

1.  Shortening the average  maturity of its portfolio in  anticipation of a rise
    in interest rates so as to minimize depreciation of principal;

2.  Lengthening  the average  maturity of its  portfolio  in  anticipation  of a
    decline in interest rates so as to maximize appreciation of principal;

3.  Selling  one type of U.S.  Government  obligation  and buying  another  when
    disparities arise in the relative values of each; and

4.  Changing from one U.S. Government  obligation to an essentially similar U.S.
    Government  obligation  when their  respective  yields are  distorted due to
    market factors.

   These  strategies  may result in increases or decreases in the Fund's current
income  available for distribution to Fund  shareholders,  and the Fund may hold
obligations  which sell at moderate to  substantial  premiums or discounts  from
face value. Moreover, if the Fund's expectations of changes in interest rates or
its evaluation of the normal yield  relationship  between two obligations proves
to be  incorrect,  the Fund's  income,  net asset value per share and  potential
capital gain may be decreased or its potential capital loss may be increased. It
is anticipated that securities invested in by this Fund will be held by the Fund
on an average from three to five years.

   While  there  is  minimal  credit  risk  involved  in the  purchase  of  U.S.
Government  securities,  as with any fixed  income  security the market value is
generally  affected  by changes in the level of interest  rates.  An increase in
interest rates will tend to reduce the market value of fixed income investments,
and a decline in interest rates will tend to increase their value.  In addition,
while debt securities  with longer  maturities  normally  produce higher yields,
they are subject to  potentially  greater  capital  changes in market value than
obligations with shorter maturities.

   The potential for appreciation in GNMAs and other MBSs, which might otherwise
be expected to occur as a result of a decline in interest rates,  may be limited
or negated by  increased  principal  prepayments  of the  underlying  mortgages.
Prepayments of MBSs occur with increasing  frequency when mortgage rates decline
because,  among  other  reasons,  mortgagors  may be  able  to  refinance  their
outstanding   mortgages  at  lower  interest  rates  or  prepay  their  existing
mortgages.  Such  prepayments  would then be reinvested by the Fund at the lower
current interest rates.

   While mortgages  underlying GNMA certificates have a stated maturity of up to
30 years,  it has been the experience of the mortgage  industry that the average
life of comparable  mortgages,  owing to prepayments,  refinancings and payments
from  foreclosures,  is  considerably  less.  Yield  tables,  published in 1981,
utilize  a  12-year  average  life  assumption  for GNMA  pools  of  26-30  year
mortgages, and GNMA certificates continue to be traded based on this assumption.
Recently it has been observed that mortgage  pools issued at high interest rates
have experienced  accelerated  prepayment rates as interest rates decline, which
would result in a shorter average life than 12 years.

HIGH YIELD FUND

   The investment  objective of High Yield Fund is to seek high current  income.
Capital appreciation is a secondary objective.  Under normal circumstances,  the
Fund will seek its investment  objective by investing primarily in a broad range
of income producing securities, including (i) higher yielding, higher risk, debt
securities  (commonly referred to as "junk bonds");  (ii) preferred stock; (iii)
securities issued by foreign governments, their

                                       6
<PAGE>
agencies and  instrumentalities,  and foreign  corporations,  provided that such
securities are  denominated in U.S.  dollars;  (iv)  mortgage-backed  securities
("MBSs"); (v) asset-backed  securities;  (vi) securities issued or guaranteed by
the U.S.  Government  or any of its  agencies  or  instrumentalities,  including
Treasury bills, certificates of indebtedness,  notes and bonds; (vii) securities
issued or guaranteed by, the Dominion of Canada or provinces thereof; and (viii)
zero  coupon  securities.  The Fund may also  invest up to 35% of its  assets in
common  stock  (which may  include  ADRs),  warrants  and rights.  Under  normal
circumstances,  at least 65% of the Fund's  total  assets  will be  invested  in
high-yielding, high risk debt securities.

   High Yield Fund may invest up to 100% of its assets in debt securities  that,
at the  time  of  purchase,  are  rated  below  investment  grade  ("high  yield
securities"  or "junk  bonds"),  which  involve  a high  degree  of risk and are
predominantly speculative. For a description of debt ratings and a discussion of
the risks associated with investing in junk bonds,  see "Investment  Methods and
Risk Factors."  Included in the debt securities  which the Fund may purchase are
convertible  bonds, or bonds with warrants  attached.  A "convertible bond" is a
bond,  debenture,  or  preferred  share which may be  exchanged by the owner for
common stock or another  security,  usually of the same  company,  in accordance
with the terms of the issue.  A "warrant"  confers  upon the holder the right to
purchase an amount of securities at a particular time and price. See "Investment
Methods and Risk  Factors" for a discussion  of the risks  associated  with such
securities.

   High  Yield  Fund may  purchase  securities  which  are  obligations  of,  or
guaranteed by, the Dominion of Canada or provinces  thereof and debt  securities
issued by Canadian  corporations.  Canadian  securities will not be purchased if
subject to the  foreign  interest  equalization  tax and unless  payable in U.S.
dollars.  The  Fund  may  also  invest  in debt  securities  issued  by  foreign
governments  (including Brady Bonds), their agencies and  instrumentalities  and
foreign  corporations  (including  those in  emerging  markets),  provided  such
securities are  denominated in U.S.  dollars.  The Fund's  investment in foreign
securities, excluding Canadian securities, will not exceed 25% of the Fund's net
assets.  See "Investment  Method and Risk Factors" for a discussion of the risks
associated with investing in foreign securities and emerging markets.

   High  Yield  Fund  may  invest  in  MBSs,  including  mortgage   pass-through
securities and collateralized  mortgage obligations (CMO's). The Fund may invest
in  securities  known as  "inverse  floating  obligations,"  "residual  interest
bonds," and "interest  only" (IO) and  "principal  only" (PO) bonds,  the market
values of which  generally  will be more volatile than the market values of most
MBSs.  This is due to the fact  that  such  instruments  are more  sensitive  to
interest  rate  changes and to the rate of principal  prepayments  than are most
other MBSs. See the discussion of such instruments under "Investment Methods and
Risk Factors." The Fund will hold less than 25% of its net assets in MBSs. For a
discussion  of  MBSs  and  the  risks  associated  with  such  securities,   see
"Investment Methods and Risk Factors."

   The Fund may also invest in "asset-backed  securities." These include secured
debt  instruments  backed by automobile  loans,  credit card loans,  home equity
loans, manufactured housing loans and other types of secured loans providing the
source of both  principal and interest.  Asset-backed  securities are subject to
risks similar to those discussed with respect to MBSs. See  "Investment  Methods
and Risk Factors."

   The Fund may invest in U.S. Government securities. U.S. Government securities
include  bills,  certificates  of  indebtedness,  notes and bonds  issued by the
Treasury or by agencies or instrumentalities of the U.S. Government.  High Yield
Fund may also invest in zero coupon  securities  which are debt  securities that
pay no cash income but are sold at substantial  discounts from their face value.
Certain  zero coupon  securities  also provide for the  commencement  of regular
interest payments at a deferred date.

   High Yield Fund may acquire  certain  securities  that are  restricted  as to
disposition under federal  securities laws,  including  securities  eligible for
resale to  qualified  institutional  investors  pursuant  to Rule 144A under the
Securities  Act of 1933,  subject to the Fund's policy that not more than 10% of
the Fund's net assets  will be  invested in  illiquid  assets.  See  "Investment
Methods and Risk Factors" for a discussion of restricted securities.
   
   The Fund may purchase securities on "when issued" or "delayed delivery" basis
in excess of customary settlement periods for the type of security involved. The
Fund may also purchase or sell  securities on a "forward  commitment"  basis and
may enter into  "repurchase  agreements",  "reverse  repurchase  agreements" and
"roll  transactions."  The Fund may lend  securities  to  broker-dealers,  other
institutions  or other persons to earn  additional  income.  The value of loaned
securities may not exceed 33 1/3% of the Fund's total assets.  In addition,  the
Fund  may  purchase  loans,  loan  participations  and  other  types  of  direct
indebtedness.
    
   High Yield Fund may enter into futures  contracts (a type of derivative)  (or
options thereon) to hedge all or a portion of its portfolio,  as a hedge against
changes in prevailing levels of interest rates or as an efficient means of

                                       7
<PAGE>
adjusting  its  exposure  to the  bond  market.  The Fund  will not use  futures
contracts  for  leveraging  purposes.  The Fund will  limit  its use of  futures
contracts so that initial margin deposits or premiums on such contracts used for
non-hedging  purposes will not equal more than 5% of the Fund's net asset value.
The Fund may purchase call and put options and write such options on a "covered"
basis.  The Fund may also enter into  interest rate and index swaps and purchase
or sell related  caps,  floors and collars.  The  aggregate  market value of the
Fund's portfolio  securities covering call or put options will not exceed 25% of
the  Fund's  net  assets.  See  "Investment  Methods  and  Risk  Factors"  for a
discussion of the risks associated with these types of investments.

   As an operating policy, the Fund will not purchase  securities on margin. The
Fund may,  however,  obtain such  short-term  credits as are  necessary  for the
clearance of purchases and sales of securities.  In addition, the Fund may enter
into certain derivative  transactions,  consistent with its investment  program,
which  require  the  deposit  of  "margin"  or a  premium  to  initiate  such  a
transaction.  As an operating  policy,  the Fund will not loan its assets to any
person or individual,  except by the purchase of bonds or other debt obligations
customarily  sold to  institutional  investors.  The  Fund  may,  however,  lend
portfolio  securities  as  described  in the  prospectus  and this  statement of
additional   information.   In  addition,  the  Fund  does  not  interpret  this
restriction as prohibiting  investment in loan participations and assignments as
described in the prospectus. As an operating policy, the Fund will not engage in
short sales.

   The Fund's  investment  in  warrants,  valued at the lower of cost or market,
will not exceed 5% of the Fund's net assets.  Included  within this amount,  but
not to exceed 2% of the Fund's net assets,  may be warrants which are not listed
on the New York or American  Stock  Exchange.  Warrants  acquired by the Fund in
units or attached to securities may be deemed to be without value.

   From time to time,  High Yield  Fund may invest  part or all of its assets in
U.S. Government securities,  commercial notes or money market instruments. It is
anticipated  that the dollar  weighted  average  maturity of the Fund will range
from 5 to 15 years under normal circumstances.
   
SECURITY MUNICIPAL BOND FUND

   The investment  objective of Municipal Bond Fund is to obtain as high a level
of interest  income  exempt from regular  federal  income taxes as is consistent
with  preservation  of  stockholders'  capital.  Municipal Bond Fund attempts to
achieve its objective by investing primarily in debt securities, the interest on
which is exempt from regular  federal  income  taxes under the Internal  Revenue
Code. The Fund may invest in securities which generate income that is subject to
the federal  alternative  minimum tax. There is no assurance that Municipal Bond
Fund's objective will be achieved.  Although there is no present intention to do
so, the Fund's  investment  objective  may be changed by the Board of  Directors
without stockholder approval.

   The tax-exempt  securities in which  Municipal Bond Fund invests include debt
obligations issued by or on behalf of the states, territories and possessions of
the United States, the District of Columbia,  and their political  subdivisions,
agencies,  authorities and instrumentalities,  including multi-state agencies or
authorities.  These securities are referred to as "municipal securities" and are
described in more detail below.

   Municipal  Bond Fund's  investments  in municipal  securities  are limited to
securities of "investment  grade" quality,  that is securities  rated within the
four highest  rating  categories of Moody's (Aaa,  Aa, A, Baa), S&P (AAA, AA, A,
BBB) or Fitch  (AAA,  AA, A, BBB),  except  that the Fund may  purchase  unrated
municipal securities (i) where the securities are guaranteed as to principal and
interest by the full faith and credit of the U.S.  government or are  short-term
municipal  securities (those having a maturity of less than one year) of issuers
having  outstanding  at the time of purchase an issue of municipal  bonds having
one of the four highest ratings, or (ii) where, in the opinion of the Investment
Manager,  the unrated  municipal  securities  are comparable in quality to those
within the four highest ratings. However,  Municipal Bond Fund will not purchase
an unrated municipal security (other than a security described in (i) above) if,
after such purchase,  more than 20% of the Fund's total assets would be invested
in such unrated municipal securities.

   With respect to rated  securities,  there is no percentage  limitation on the
amount of  Municipal  Bond Fund's  assets  which may be  invested in  securities
within any  particular  rating  classification.  A description of the ratings is
contained in Appendix B to the Prospectus. Baa securities are considered "medium
grade"  obligations by Moody's,  and BBB is the lowest  classification  which is
still  considered an "investment  grade" rating by S&P and Fitch. Baa securities
are  described  by  Moody's  as  obligations  on which  "interest  payments  and
principal  security  appear  adequate  for the present  but  certain  protective
elements may be lacking or may be  characteristically  unreliable over any great
length of time." According to Moody's, "such bonds lack outstanding investment

                                       8
<PAGE>
characteristics and in fact have speculative characteristics as well." According
to Fitch,  "adverse changes in economic  conditions and  circumstances  are more
likely to have  adverse  impact on these  bonds,  and  therefore  impair  timely
payment."  The  ratings of Moody's,  S&P and Fitch  represent  their  respective
opinions  of the  quality  of the  securities  they  undertake  to rate and such
ratings are general and are not absolute standards of quality.

   Although  Municipal  Bond Fund  invests  primarily  in  municipal  bonds with
maturities  greater than one year,  it also will invest for various  purposes in
short-term  (maturity equal to or less than one year)  securities  which, to the
extent practicable,  will be short-term  municipal  securities.  (See "Municipal
Securities,"  below.) Short-term  investments may be made, pending investment of
funds in municipal  bonds,  in order to maintain  liquidity  to meet  redemption
requests,  or to maintain a temporary  "defensive"  investment position when, in
the opinion of the  Investment  Manager,  it is advisable to do so on account of
current or anticipated market conditions. Except when in a temporary "defensive"
position,  investments in short-term  municipal  securities  will represent less
than 20% of the Fund's total assets.

   From time to time, on a temporary  basis,  Municipal  Bond Fund may invest in
fixed-income obligations on which the interest is subject to federal income tax.
Except when the Fund is in a temporary "defensive"  investment position, it will
not  purchase  a taxable  security  if, as a result,  more than 20% of its total
assets would be invested in taxable securities. This limitation is a fundamental
policy of Municipal Bond Fund, and may not be changed without a majority vote of
the Fund's outstanding securities. Temporary taxable investments of the Fund may
consist  of  obligations  issued or  guaranteed  by the U.S.  government  or its
agencies or  instrumentalities,  commercial  paper rated A-1 by S&P,  Prime-1 by
Moody's or F-1 by Fitch,  corporate obligations rated AAA or AA by S&P and Fitch
or Aaa or Aa by  Moody's,  certificates  of deposit or bankers'  acceptances  of
domestic  banks or thrifts  with at least $2 billion  in assets,  or  repurchase
agreements  with  such  banks or with  broker/dealers.  Municipal  Bond Fund may
invest  its  assets  in  bank  demand  accounts,  pending  investment  in  other
securities or to meet potential  redemptions or expenses.  Repurchase agreements
may be entered into with respect to any  securities  eligible for  investment by
the  Fund,  including  municipal  securities.  The Fund may also  invest in zero
coupon securities which are debt securities that pay no cash income but are sold
at substantial  discounts from their face value.  Certain zero coupon securities
also provide for the  commencement  of regular  interest  payments at a deferred
date.

   Municipal Bond Fund may invest in repurchase  agreements which are agreements
by which a  purchaser  (e.g.,  Municipal  Bond Fund)  acquires  a  security  and
simultaneously  commits  to  resell  that  security  to the  seller  (a  bank or
broker/dealer) at an agreed upon price on an agreed upon date within a number of
days  (usually not more than seven) from the date of purchase.  Income earned by
the Fund on repurchase  agreements is not exempt from federal income tax even if
the transaction involves municipal securities. Municipal Bond Fund may not enter
into a repurchase  agreement  having more than seven days  remaining to maturity
if, as a result,  such agreements,  together with any other securities which are
illiquid or not readily  marketable,  would  exceed 10% of the net assets of the
Fund. See the discussion of repurchase  agreements under "Investment Methods and
Risk Factors."

   Municipal  Bond Fund may borrow  money from banks as a temporary  measure for
emergency purposes or to facilitate redemption requests.  Borrowing is discussed
in more detail under "Investment  Methods and Risk Factors." Pending  investment
in  securities  or to  meet  potential  redemptions,  the  Fund  may  invest  in
certificates  of deposit,  bank demand  accounts and high  quality  money market
instruments.

   Municipal  Bond  Fund may  purchase  or sell  futures  contracts  on (a) debt
securities that are backed by the full faith and credit of the U.S.  Government,
such as long-term U.S.  Treasury Bonds and Treasury Notes and (b) municipal bond
indices. Currently at least one exchange trades futures contracts on an index of
long-term  municipal  bonds,  and the Fund reserves to right to conduct  futures
transactions based on an index which may be developed in the future to correlate
with price movements in municipal  obligations.  It is not presently anticipated
that any of these  strategies will be used to a significant  degree by the Fund.
For further information regarding futures contracts, see "Investment Methods and
Risk Factors".

   See Appendix B to the  prospectus for a further  description of Moody's,  S&P
and Fitch  ratings  relating to municipal  securities.  As noted  earlier,  when
Municipal Bond Fund is in a temporary "defensive" position, there is no limit on
its investments in short-term municipal securities and taxable securities.

MUNICIPAL SECURITIES

   MUNICIPAL BONDS.  Municipal bonds are debt obligations which generally have a
maturity  at the time of issue in excess of one year.  They are issued to obtain
funds for various public  purposes,  including  construction  of a wide range of
public  facilities  such  as  bridges,   highways,   housing,   hospitals,  mass
transportation,  schools,  streets,  and  water and sewer  works.  Other  public
purposes  for which  municipal  bonds may be issued  include  the  refunding  of
outstanding  obligations,  obtaining  funds for general  operating  expenses and
obtaining  funds  to  loan to  other  public  institutions  and  facilities.  In
addition,  certain  types of  industrial  development  bonds and  other  private
activity bonds are issued by or on behalf of public  authorities to obtain funds
to provide for privately-operated housing facilities, and certain facilities for
water supply, gas, electricity or sewage or solid waste disposal.
   
   The two principal classifications of municipal bonds are "general obligation"
and "revenue" bonds. General obligation bonds are secured by the issuer's pledge
of its full  faith,  credit and taxing  power for the payment of  principal  and
interest.  Revenue  bonds are  payable  only from the  revenues  derived  from a
particular facility or class of facilities, or, in some cases, from the proceeds
of a special excise or specific revenue source.  Revenue  securities may include
private  activity  bonds.  Such  bonds  may be  issued by or on behalf of public
authorities to finance various privately operated facilities and are not payable
from the unrestricted revenues of the issuer. As a result, the credit quality of
private activity bonds is frequently  related directly to the credit standing of
private  corporations  or other entities.  In addition,  the interest on private
activity bonds issued after August 7, 1986 is subject to the federal alternative
minimum tax. The Fund will not be restricted  with respect to the  proportion of
its assets that may be invested in such obligations.  Accordingly,  the Fund may
not be a suitable  investment  vehicle for individuals or corporations  that are
subject to the federal  alternative  minimum tax.  Municipal  Bond Fund will not
invest  more than 5% of its net assets in  securities  where the  principal  and
interest are the  responsibility of a private  corporation or other entity which
has, including predecessors, less than three years' operational history.

   There are, depending on numerous factors, variations in the risks involved in
holding municipal securities, both within a particular rating classification and
between  classifications.  The market values of outstanding municipal bonds will
vary as a result of the  rating of the issue  and  changing  evaluations  of the
ability of the issuer to meet  interest  and  principal  payments.  Such  market
values will also change in response to changes in the interest  rates payable on
new issues of municipal  bonds.  Should such interest  rates rise, the values of
outstanding  bonds,  including  those held in Municipal  Bond Fund's  portfolio,
would decline;  should such interest  rates  decline,  the values of outstanding
bonds would increase.
    
   As a result of litigation or other  factors,  the power or ability of issuers
of municipal  securities to pay  principal  and/or  interest  might be adversely
affected.  Municipal  securities  are subject to the  provisions of  bankruptcy,
insolvency and other laws  affecting the rights and remedies of creditors,  such
as the  Federal  Bankruptcy  Code,  and laws,  if any,  which may be  enacted by
Congress or state  legislatures  extending  the time for payment of principal or
interest  or both,  or  imposing  other  constraints  upon  enforcement  of such
obligations or upon the power of municipalities to levy taxes.
   
   Municipal  Bond Fund may invest without  percentage  limitations in issues of
municipal securities which have similar characteristics, such as the location of
their  issuers  in the same  geographic  region or the  derivation  of  interest
payments  from  revenues on similar  projects  (for  example,  electric  utility
systems,  hospitals, or housing finance agencies). Thus, Municipal Bond Fund may
invest more than 25% of its total assets in securities issued in a single state.
However,  it may not invest more than 25% of its total  assets in one  industry.
(See  "Investment  Policy  Limitations,"  page  26.)  Consequently,  the  Fund's
portfolio  of  municipal  securities  may be more  susceptible  to the  risks of
adverse economic,  political,  or regulatory developments than would be the case
with a portfolio of securities  required to be more diversified as to geographic
region and/or source of revenue.

   Interest on certain types of private activity bonds (for example, obligations
to finance certain exempt  facilities  which may be leased to or used by persons
other than the issuer) will not be exempt from federal  income tax when received
by "substantial  users" or persons related to "substantial  users" as defined in
the Internal Revenue Code. The term  "substantial  user" generally  includes any
"non-exempt person" who regularly uses in trade or business a part of a facility
financed from the proceeds of private  activity  bonds.  Municipal Bond Fund may
invest  periodically  in private  activity bonds and,  therefore,  may not be an
appropriate  investment for entities which are  substantial  users of facilities
financed by those bonds or "related persons" of substantial users. Generally, an
individual  will not be a related  person of a  substantial  user under the Code
unless the person or his immediate

                                       10
<PAGE>
family (spouse, brothers, sisters and lineal descendants) directly or indirectly
owns in the  aggregate  more than 50% in value of the equity of the  substantial
user.

   From time to time,  proposals have been  introduced  before  Congress for the
purpose of  restricting  or  eliminating  the federal  income tax  exemption for
interest on future  issues of  municipal  securities.  It can be  expected  that
similar  proposals  may be  introduced  in the future.  If such a proposal  were
enacted,  the  availability of municipal  securities for investment by Municipal
Bond Fund and the  value of the  Fund's  portfolio  would be  affected.  In that
event,  the  Directors  would  reevaluate  the Fund's  investment  objective and
policies.

   WHEN-ISSUED PURCHASES. From time to time, in the ordinary course of business,
Municipal  Bond Fund may  purchase  municipal  securities  on a  when-issued  or
delayed  delivery  basis--i.e.,  delivery  and payment can take place a month or
more after the date of the transactions.  Securities so purchased are subject to
market  fluctuation and no interest accrues to the purchaser during this period.
At the time the Fund makes the commitment to purchase a municipal  security on a
when-issued  or delayed  delivery  basis,  it will  record the  transaction  and
thereafter  reflect the value,  each day, of the security in determining its net
asset value.  Municipal Bond Fund will also establish a segregated  account with
its custodian bank in which it will maintain cash or liquid  securities equal in
value to  commitments  for such  when-issued  or  delayed  delivery  securities.
Municipal  Bond Fund does not believe that its net asset value or income will be
adversely  affected by its purchase of municipal  securities on a when-issued or
delayed delivery basis. Upon the settlement date of the when-issued  securities,
the Fund  ordinarily  will meet its obligation to purchase the  securities  from
available cash flow, use of the cash (or liquidation of securities)  held in the
segregated  account or sale of other securities.  Although it would not normally
expect  to do so,  the Fund  also may meet its  obligation  from the sale of the
when-issued securities themselves (which may have a current market value greater
or less than the Fund's  payment  obligation).  Sale of  securities to meet such
obligations  carries  with it a greater  potential  for the  realization  of net
capital gains, which are not exempt from federal income tax.

   PUTS OR STAND-BY COMMITMENTS. Municipal Bond Fund may purchase, from banks or
broker/dealers,  municipal  securities  together  with the right to  resell  the
securities  to the seller at an  agreed-upon  price or yield  within a specified
period prior to the maturity date of the  securities.  Such a right to resell is
commonly known as a "put" and is also referred to as a "stand-by  commitment" on
the  part of the  seller.  The  price  which  the Fund  pays  for the  municipal
securities with puts generally is higher than the price which otherwise would be
paid for the  municipal  securities  alone.  Municipal  Bond  Fund uses puts for
liquidity  purposes  in order to permit  it to remain  more  fully  invested  in
municipal  securities  than would  otherwise  be the case by  providing  a ready
market for certain municipal securities in its portfolio at an acceptable price.
The put  generally  is for a shorter  term than the  maturity  of the  municipal
security and does not  restrict in any way the Fund's  ability to dispose of (or
retain) the municipal security.
    
   In order to ensure that the interest on municipal  securities subject to puts
is  tax-exempt  to the Fund,  it will limit its use of puts in  accordance  with
current  interpretations  or rulings of the Internal  Revenue Service (IRS). The
IRS has  issued a ruling  (Rev.  Rul.  82-144)  in  which it  determined  that a
regulated  investment  company was the owner,  for tax  purposes,  of  municipal
securities  subject to puts (with the result that  interest on those  securities
would not lose its tax-exempt status when paid to the company). The IRS position
in Rev. Rul. 82-144 relates to a particular factual situation,  in which (i) the
price paid for the puts was in addition to the price of the municipal securities
subject  to the puts,  (ii) the puts  established  the price at which the seller
must repurchase the securities, (iii) the puts were nonassignable and terminated
upon disposal of the underlying  securities by the Fund,  (iv) the puts were for
periods substantially less than the terms of the underlying securities,  (v) the
puts  did  not  include  call  arrangements  or  restrict  the  disposal  of the
underlying  securities  by the  Fund  and  gave  the  seller  no  rights  in the
underlying securities, and (vi) the securities were acquired by the Fund for its
own account and not as security for a loan from the seller.
   
   Because it is  difficult  to  evaluate  the  likelihood  of  exercise  or the
potential  benefit of a put,  puts will be determined to have a "value" of zero,
regardless  of whether any direct or indirect  consideration  was paid.  Amounts
paid  by  Municipal  Bond  Fund  for a  put  will  be  reflected  as  unrealized
depreciation  in the  underlying  security  for  the  period  during  which  the
commitment is held, and therefore will reduce any potential gains on the sale of
the underlying  security by the cost of the put. There is a risk that the seller
of the put may not be able to  repurchase  the security upon exercise of the put
by the Fund.

   SHORT-TERM  MUNICIPAL  SECURITIES.  Although  Municipal Bond Fund's portfolio
generally will consist primarily of municipal bonds, for liquidity purposes, and
from time to time for defensive purposes, a portion of its

                                       11
<PAGE>
assets may be invested in short-term municipal securities (i.e., those with less
than one year remaining to maturity).
    
   Short-term  municipal  securities  consist of short-term  municipal notes and
short-term  municipal loans and obligations,  including  municipal paper, master
demand notes and variable-rate demand notes.  Short-term municipal notes include
tax  anticipation  notes  (notes  issued in  anticipation  of the receipt of tax
funds),  bond anticipation notes (notes issued in anticipation of receipt of the
proceeds  of bond  placements),  revenue  anticipation  notes  (notes  issued in
anticipation  of the receipt of revenues  other than taxes or bond  placements),
and  project  notes  (obligations  of  municipal  housing  agencies on which the
payment of  principal  and interest  ordinarily  is backed by the full faith and
credit of the U.S.  government).  Municipal paper typically consists of the very
short-term unsecured negotiable promissory notes of municipal issuers.
   
   The Fund may invest in tax-exempt  master demand  notes.  A municipal  master
demand  note is an  arrangement  under  which  the Fund  participates  in a note
agreement  between  a bank  acting  on behalf  of its  clients  and a  municipal
borrower, whereby amounts maintained by the Fund in an account with the bank are
provided to the municipal borrower and payments of interest and principal on the
note are credited to the Fund's  account.  Interest rates on master demand notes
typically are tied to market interest rates,  and therefore may fluctuate daily.
The amounts borrowed under these notes may be repaid at any time by the borrower
without penalty, and must be repaid upon the demand of Municipal Bond Fund.

   Municipal  Bond  Fund  may  also  invest  in   variable-rate   demand  notes.
Variable-rate  demand notes are tax-exempt  obligations which are payable by the
municipal  issuer  at par  value  plus  accrued  interest  on demand by the Fund
(generally with three to ten days' notice).  If no demand is made, the note will
mature on a specified  date from one to thirty years from its issuance.  Payment
on the note may be  backed  by a  stand-by  letter  of  credit.  The  yield on a
variable  rate  demand note is adjusted  automatically  to reflect a  particular
market  rate  (which may not be the same  market  rate as that  applicable  to a
master demand note).  Variable-rate  demand notes  typically are callable by the
issuer prior to maturity.

   Where short-term municipal securities are rated, the Municipal Bond Fund will
limit its investments to "high quality"  short-term  securities.  For short-term
municipal notes this includes  ratings of SP-2 or better by S&P, MIG 2 or better
(or VMIG-2 or better,  in the case of variable  rate demand notes) by Moody's or
F-2 or better by Fitch;  for municipal paper this includes A-2 or better by S&P,
Prime-2  or better by  Moody's  or F-2 or  better by Fitch.  Unrated  short-term
municipal  securities will be included  within the Fund's overall  limitation on
investments in unrated municipal  securities.  This limitation provides that not
more than 20% of  Municipal  Bond Fund's total assets may be invested in unrated
municipal securities, exclusive of unrated securities which are guaranteed as to
principal  and interest by the full faith and credit of the U.S.  government  or
are issued by an issuer having  outstanding  an issue of municipal  bonds within
one of the four highest ratings classifications.

   Municial Bond Fund also may engage to a limited  extent in portfolio  trading
consistent with its investment objective. Securities may be sold in anticipation
of a market decline (a rise in interest rates) or purchased in anticipation of a
market  rise (a decline  in  interest  rates) and later  sold.  In  addition,  a
security  may  be  sold  and  another  of   comparable   quality   purchased  at
approximately  the same time to take advantage of what the Fund believes to be a
temporary disparity in the normal yield relationship between the two securities.
These  yield  disparities  may occur for  reasons  not  directly  related to the
investment  quality of a  particular  issue or the general  movement of interest
rates, such as changes in the overall demand for, or supply of, various types of
municipal securities.
    
SECURITY CASH FUND

   The  investment  objective of Cash Fund is to seek as high a level of current
income  as  is  consistent  with  preservation  of  capital  and  liquidity.  No
assurances can be given that Cash Fund will achieve its objective. The Fund will
attempt to achieve its  objective by investing at least 95% of its total assets,
measured  at the time of  investment,  in a  diversified  portfolio  of  highest
quality  money  market  instruments.  Cash Fund may also  invest up to 5% of its
total assets,  measured at the time of investment,  in money market  instruments
that are in the second-highest  rating category for short-term debt obligations.
Money market instruments in which Cash Fund may invest consist of the following:

   U.S. GOVERNMENT SECURITIES. Obligations issued or guaranteed (as to principal
or interest) by the United States  Government or its agencies (such as the Small
Business Administration, the Federal Housing

                                       12
<PAGE>
Administration    and   Government    National    Mortgage    Association)    or
instrumentalities  (such as Federal  Home Loan Banks and Federal Land Banks) and
instruments fully collateralized with such obligations.

   BANK OBLIGATIONS.  Obligations of banks or savings and loan associations that
are members of the Federal Deposit  Insurance  Corporation and instruments fully
collateralized with such obligations.

   CORPORATE  OBLIGATIONS.  Commercial  paper issued by  corporations  and rated
Prime-1 or Prime-2 by  Moody's,  or A-1 or A-2 by S&P, or other  corporate  debt
instruments  rated Aaa or Aa or better by Moody's or AAA or AA or better by S&P,
subject to the  limitations on investment in  instruments in the  second-highest
rating category, discussed below.

   Cash Fund may invest in certificates of deposit issued by banks or other bank
demand  accounts,  pending  investment in other  securities or to meet potential
redemptions or expenses.

   Cash Fund may invest only in U.S. dollar denominated money market instruments
that present  minimal  credit risk and, with respect to 95% of its total assets,
measured  at the  time of  investment,  that  are of the  highest  quality.  The
Investment  Manager will determine  whether a security  presents  minimal credit
risk under procedures adopted by the Fund's Board of Directors.  A security will
be considered to be highest quality (1) if rated in the highest rating category,
(e.g., Aaa or Prime-1 by Moody's or AAA or A-1 by S&P) by (i) any two nationally
recognized  statistical  rating  organizations  ("NRSRO's") or, (ii) if rated by
only one NRSRO,  by that NRSRO;  (2) if issued by an issuer that has  short-term
debt  obligations of comparable  maturity,  priority,  and security and that are
rated in the highest rating category by (i) any two NRSRO's or, (ii) if rated by
only one NRSRO, by that NRSRO; or (3) an unrated  security that is of comparable
quality to a security  in the  highest  rating  category  as  determined  by the
Investment Manager and whose acquisition is approved or ratified by the Board of
Directors.  With  respect  to 5% of its total  assets,  measured  at the time of
investment,  Cash Fund may also invest in money market  instruments  that are in
the second-highest  rating category for short-term debt obligations (e.g., rated
Aa or Prime-2 by Moody's or AA or A-2 by S&P). A money market instrument will be
considered  to be in the  second-highest  rating  category  under  the  criteria
described  above with respect to  instruments  considered  highest  quality,  as
applied to instruments in the second-highest rating category.  See Appendix A to
the  Prospectus  for a  description  of the principal  types of  securities  and
instruments  in which the Fund will invest as well as a description of the above
mentioned ratings.

   Cash Fund may not invest  more than 5% of its total  assets,  measured at the
time of investment,  in the securities of any one issuer that are of the highest
quality  or more  than the  greater  of 1% of its total  assets  or  $1,000,000,
measured at the time of investment,  in securities of any one issuer that are in
the  second-highest  rating category,  except that these  limitations  shall not
apply to U.S. Government  securities.  The Fund may exceed the 5% limitation for
up to three business days after the purchase of the securities of any one issuer
that  are of  the  highest  quality,  provided  that  the  Fund  does  not  have
outstanding  at any time more  than one such  investment.  In the event  that an
instrument acquired by Cash Fund is downgraded,  the Investment  Manager,  under
procedures approved by the Board of Directors, (or the Board of Directors itself
if the  Investment  Manager  becomes  aware that a security has been  downgraded
below the  second-highest  rating  category and the Investment  Manager does not
dispose of the  security  within five  business  days) shall  promptly  reassess
whether such security  presents minimal credit risk and determine whether or not
to retain the instrument.  In the event that an instrument acquired by Cash Fund
ceases  to be of the  quality  that is  eligible  for the Fund,  the Fund  shall
promptly  dispose of the  instrument  in an orderly  manner  unless the Board of
Directors determines that this would not be in the best interests of the Fund.

   Cash Fund may acquire one or more of the above types of securities subject to
repurchase agreements.  A repurchase transaction involves a purchase by the Fund
of a security from a selling financial institution,  such as a bank, savings and
loan association or broker/dealer, which agrees to repurchase such security at a
specified  price and at a fixed time in the future,  usually not more than seven
days from the date of  purchase.  Not more than 10% of Cash Fund's  total assets
will be invested in illiquid assets,  which include  repurchase  agreements with
maturities of over seven days. See the discussion of repurchase agreements under
"Investment Methods and Risk Factors."

   Cash Fund may borrow  money from banks as a temporary  measure for  emergency
purposes or to facilitate  redemption  requests.  Borrowing is discussed in more
detail  under  "Investment  Methods and Risk  Factors."  Pending  investment  in
securities or to meet potential redemptions, the Fund may invest in certificates
of deposit, bank demand accounts and high quality money market instruments.

   RULE 144A SECURITIES.  Certain of the securities acquired by Cash Fund may be
restricted as to disposition under federal  securities laws,  provided that such
restricted securities are eligible for resale to qualified institutional

                                       13
<PAGE>
investors  pursuant to Rule 144A under the Securities Act of 1933. Rule 144A was
adopted  by the  Securities  and  Exchange  Commission  (the  "SEC")  under  the
Securities Act of 1933, as amended (the "Securities Act") in 1990. It provides a
nonexclusive  safe harbor  exemption from the  registration  requirements of the
Securities Act for the resale of certain securities to certain qualified buyers.
One of the primary  purposes of the Rule is to create some resale  liquidity for
certain securities that would otherwise be treated as illiquid  investments.  In
accordance with Cash Fund's  policies,  the Fund is not permitted to invest more
than 10% of its total net assets in illiquid  securities.  See the discussion of
Rule 144A Securities under "Investment Methods and Risk Factors."

   VARIABLE RATE INSTRUMENTS.  Cash Fund may invest in instruments  having rates
of interest that are adjusted periodically  according to a specified market rate
for such  investments  ("Variable  Rate  Instruments").  The interest  rate on a
Variable  Rate  Instrument  is  ordinarily  determined  by reference to, or is a
percentage  of, an objective  standard such as a bank's prime rate or the 91-day
U.S.  Treasury  Bill rate.  Cash Fund does not purchase  certain  Variable  Rate
Instruments  that have a preset  cap above  which the rate of  interest  may not
rise.  Generally,  the changes in the interest rate on Variable Rate Instruments
reduce the fluctuation in the market value of such securities.  Accordingly,  as
interest rates decrease or increase,  the potential for capital  appreciation or
depreciation is less than for fixed-rate  obligations.  Cash Fund determines the
maturity of Variable Rate  Instruments  in  accordance  with Rule 2a-7 under the
Investment  Company Act of 1940 which  allows the Fund to consider  the maturity
date of such instruments to be the period remaining until the next  readjustment
of  the  interest  rate  rather  than  the  maturity  date  on the  face  of the
instrument.

   While Cash Fund does not intend to engage in  short-term  trading,  portfolio
securities  may be sold without regard to the length of time that they have been
held. A portfolio  security could be sold prior to maturity to take advantage of
new investment  opportunities  or yield  differentials,  or to preserve gains or
limit losses due to changing economic  conditions or the financial  condition of
the  issuer,  or for other  reasons.  While Cash Fund is expected to have a high
portfolio turnover due to the short maturities of its portfolio securities, this
should  not  affect  the  Fund's  income  or net  asset  value  since  brokerage
commissions  are not normally  paid in  connection  with the purchase or sale of
money market instruments.

   Cash Fund will invest in money market  instruments of varying maturities (but
no longer than 13 months) in an effort to earn as high a level of current income
as is consistent with preservation of capital and liquidity. The Fund intends to
maintain a weighted  average maturity in its portfolio of not more than 90 days.
In  addition  to  general  market  risks,   Fund  investments  in  nongovernment
obligations are subject to the ability of the issuer to satisfy its obligations.

   Cash Fund also  intends  to  maintain  a net asset  value per share of $1.00,
although  there can be no  assurance  it will be able to do so. It is the Fund's
policy to  declare  dividends  on a daily  basis of an  amount  equal to the net
income plus or minus any realized  capital gains or losses.  (See "Dividends and
Taxes," page 51.)

INVESTMENT METHODS AND RISK FACTORS

   Some of the risk  factors  related to  certain  securities,  instruments  and
techniques  that may be used by one or more of the  Funds are  described  in the
"Investment  Objectives and Policies" and "Investment  Methods and Risk Factors"
sections of the Prospectus and in this Statement of Additional Information.  The
following is a description of certain additional risk factors related to various
securities,  instruments  and  techniques.  The risks so described only apply to
those Funds which may invest in such  securities  and  instruments  or which use
such  techniques.  Also  included  is a  general  description  of  some  of  the
investment instruments,  techniques and methods which may be used by one or more
of the Funds. The methods described only apply to those Funds which may use such
methods.  Although a Fund may employ the  techniques,  instruments  and  methods
described below,  consistent with its investment  objective and policies and any
applicable law, no Fund will be required to do so.

   GENERAL RISK FACTORS. Each Fund's net asset value will fluctuate,  reflecting
fluctuations in the market value of its portfolio  positions and, if applicable,
its net  currency  exposure.  The value of fixed income  securities  held by the
Funds  generally  fluctuates  inversely with interest rate  movements.  In other
words,  bond prices  generally fall as interest rates rise and generally rise as
interest rates fall.  Longer term bonds held by the Funds are subject to greater
interest  rate  risk.  There is no  assurance  that any Fund  will  achieve  its
investment objective.

   REPURCHASE  AGREEMENTS,  REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS.
Each of the Funds may enter into repurchase  agreements.  Repurchase  agreements
are  transactions  in which the  purchaser  buys a debt  security from a bank or
recognized securities dealer and simultaneously  commits to resell that security
to the bank or dealer at an agreed upon price,  date and market rate of interest
unrelated to the coupon rate or maturity of

                                       14
<PAGE>
the purchased security.  Repurchase  agreements are considered to be loans which
must be fully collateralized including interest earned thereon during the entire
term of the agreement.  If the institution defaults on the repurchase agreement,
the Fund will retain  possession  of the  underlying  securities.  If bankruptcy
proceedings  are  commenced  with  respect  to the  seller,  realization  on the
collateral  by the Fund  may be  delayed  or  limited  and the  Fund  may  incur
additional  costs.  In such case,  the Fund will be subject to risks  associated
with changes in market value of the collateral  securities.  The Fund intends to
enter into repurchase agreements only with banks and broker/dealers  believed to
present minimal credit risks. Accordingly,  the Funds will enter into repurchase
agreements  only with (a) brokers  having total  capitalization  of at least $40
million and a ratio of aggregate  indebtedness  to net capital of no more than 4
to 1, or, alternatively, net capital equal to 6% of aggregate debit balances, or
(b) banks  having at least $1 billion in assets and a net worth of at least $100
million  as of its  most  recent  annual  report.  In  addition,  the  aggregate
repurchase  price of all repurchase  agreements held by the Fund with any broker
shall not exceed 15% of the total assets of the Fund or $5 million, whichever is
greater.

   The High Yield Fund may also enter into reverse  repurchase  agreements  with
the same  parties  with whom it may enter into  repurchase  agreements.  Under a
reverse  repurchase  agreement,  the Fund  would  sell  securities  and agree to
repurchase  them at a  particular  price at a future  date.  Reverse  repurchase
agreements involve the risk that the market value of the securities  retained in
lieu of sale by a Fund may decline  below the price of the  securities  the Fund
has sold but is obligated to  repurchase.  In the event the buyer of  securities
under a reverse repurchase  agreement files for bankruptcy or becomes insolvent,
such buyer or its  trustee or  receiver  may  receive  an  extension  of time to
determine whether to enforce the Fund's obligation to repurchase the securities,
and the Fund's use of the  proceeds  of the  reverse  repurchase  agreement  may
effectively be restricted pending such decision.

   The High  Yield Fund also may enter  into  "dollar  rolls," in which the Fund
sells  fixed  income   securities   for  delivery  in  the  current   month  and
simultaneously  contracts to repurchase substantially similar (same type, coupon
and maturity) securities on a specified future date. During the roll period, the
Fund would forego principal and interest paid on such securities. The Fund would
be compensated by the difference between the current sales price and the forward
price for the future  purchase,  as well as by the  interest  earned on the cash
proceeds of the initial sale.

   BORROWING.  Each of the Funds may  borrow  money  from  banks as a  temporary
measure for emergency purposes, or to facilitate redemption requests.
   
   From time to time,  it may be  advantageous  for the  Funds to  borrow  money
rather than sell  existing  portfolio  positions  to meet  redemption  requests.
Accordingly,  the Funds may  borrow  from  banks and High  Yield Fund may borrow
through reverse  repurchase  agreements and "roll"  transactions,  in connection
with meeting  requests for the  redemption  of Fund shares.  High Yield Fund may
borrow up to 33 1/3%,  Limited Maturity Bond,  Municipal Bond and Cash Funds may
each  borrow up to 10% and  Corporate  Bond and U.S.  Government  Funds may each
borrow  up to 5% of total  Fund  assets.  To the  extent  that a Fund  purchases
securities while it has outstanding borrowings, it is using leverage, i.e. using
borrowed  funds for  investment.  Leveraging  will  exaggerate the effect on net
asset  value  of any  increase  or  decrease  in the  market  value  of a Fund's
portfolio.  Money borrowed for leveraging will be subject to interest costs that
may or may not be recovered by  appreciation  of the  securities  purchased;  in
certain cases,  interest costs may exceed the return  received on the securities
purchased.  A Fund also may be required to maintain  minimum average balances in
connection with such borrowing or to pay a commitment or other fee to maintain a
line of  credit;  either  of  these  requirements  would  increase  the  cost of
borrowing over the stated interest rate. It is not expected that Cash Fund would
purchase securities while it had borrowings outstanding.
    
   LENDING  OF  PORTFOLIO  SECURITIES.  For the  purpose of  generating  income,
certain of the Funds may make secured loans of Fund securities  amounting to not
more  than  33  1/3%  of  its  total  assets.   Securities  loans  are  made  to
broker/dealers, institutional investors, or other persons pursuant to agreements
requiring that the loans be continuously secured by collateral at least equal at
all times to the value of the securities lent marked to market on a daily basis.
The  collateral  received  will  consist of cash,  U.S.  Government  securities,
letters  of  credit  or such  other  collateral  as may be  permitted  under its
investment program.  While the securities are being lent, the Fund will continue
to receive the equivalent of the interest or dividends paid by the issuer on the
securities,  as well as interest on the  investment  of the  collateral or a fee
from  the  borrower.  The  Fund has a right to call  each  loan and  obtain  the
securities  on five  business  days' notice or, in  connection  with  securities
trading on foreign  markets,  within such longer period of time which  coincides
with the normal settlement period for purchases and sales of

                                       15
<PAGE>
such  securities  in such foreign  markets.  The Fund will not have the right to
vote  securities  while  they  are  being  lent,  but it  will  call  a loan  in
anticipation of any important vote. The risks in lending  portfolio  securities,
as with  other  extensions  of secured  credit,  consist  of  possible  delay in
receiving additional collateral or in the recovery of the securities or possible
loss of rights in the  collateral  should the borrower fail  financially.  Loans
will only be made to  persons  deemed by the  Investment  Manager  to be of good
standing and will not be made unless, in the judgment of the Investment Manager,
the consideration to be earned from such loans would justify the risk.

   RESTRICTED SECURITIES (RULE 144A SECURITIES). Certain of the Funds may invest
in  restricted  securities  which  are  securities  that  are  restricted  as to
disposition under the federal securities laws, provided that such securities are
eligible for resale to qualified  institutional  investors pursuant to Rule 144A
under the  Securities  Act of 1933.  Rule 144A permits the resale to  "qualified
institutional buyers" of "restricted  securities" that, when issued, were not of
the same class as securities listed on a U.S.  securities  exchange or quoted in
the National  Association of Securities Dealers Automated  Quotation System (the
"Rule 144A Securities").  A "qualified  institutional  buyer" is defined by Rule
144A generally as an institution, acting for its own account or for the accounts
of other qualified  institutional buyers, that in the aggregate owns and invests
on a  discretionary  basis at least $100  million in  securities  of issuers not
affiliated  with the  institution.  A dealer  registered  under  the  Securities
Exchange  Act of 1934 (the  "Exchange  Act"),  acting for its own account or the
accounts of other qualified institutional buyers, that in the aggregate owns and
invests on a  discretionary  basis at least $10 million in securities of issuers
not  affiliated  with the dealer may also  qualify as a qualified  institutional
buyer,  as well as an  Exchange  Act  registered  dealer  acting  in a  riskless
principal transaction on behalf of a qualified institutional buyer.

   The Funds' Board of Directors is responsible for developing and  establishing
guidelines and procedures for determining the liquidity of Rule 144A Securities.
As  permitted  by  Rule  144A,   the  Board  of  Directors  has  delegated  this
responsibility to the Investment Manager. In making the determination  regarding
the  liquidity of Rule 144A  Securities,  the  Investment  Manager will consider
trading markets for the specific  security taking into account the  unregistered
nature  of a Rule  144A  security.  In  addition,  the  Investment  Manager  may
consider:  (1) the frequency of trades and quotes; (2) the number of dealers and
potential  purchasers;  (3) dealer  undertakings  to make a market;  and (4) the
nature of the security and of the market place trades (e.g.,  the time needed to
dispose of the security,  the method of  soliciting  offers and the mechanics of
transfer). Investing in Rule 144A Securities could have the effect of increasing
the amount of a Fund's assets invested in illiquid securities to the extent that
qualified  institutional buyers become  uninterested,  for a time, in purchasing
these securities.

   The High  Yield Fund also may  purchase  restricted  securities  that are not
eligible for resale  pursuant to Rule 144A. The Fund may acquire such securities
through  private  placement  transactions,  directly  from  the  issuer  or from
security  holders,  generally  at higher  yields or on terms more  favorable  to
investors than comparable publicly traded securities.  However, the restrictions
on resale of such  securities  may make it difficult  for the Fund to dispose of
such  securities at the time considered  most  advantageous,  and/or may involve
expenses that would not be incurred in the sale of  securities  that were freely
marketable.  Risks associated with restricted  securities  include the potential
obligation  to pay all or part of the  registration  expenses  in  order to sell
certain restricted securities.  A considerable period of time may elapse between
the  time of the  decision  to sell a  security  and the  time  the  Fund may be
permitted to sell it under an effective  registration  statement.  If,  during a
period,  adverse  conditions  were to  develop,  the  Fund  might  obtain a less
favorable price than prevailing when it decided to sell.

   RISKS ASSOCIATED WITH  LOWER-RATED  DEBT SECURITIES (JUNK BONDS).  Certain of
the Funds may invest in higher  yielding  debt  securities  in the lower  rating
(higher risk) categories of the recognized rating services (commonly referred to
as "junk  bonds").  Debt rated BB, B, CCC, CC and C by S&P and rated Ba, B, Caa,
Ca and C by Moody's, is regarded, on balance, as predominantly  speculative with
respect  to the  issuer's  capacity  to pay  interest  and  repay  principal  in
accordance  with the terms of the  obligation.  For S&P, BB indicates the lowest
degree of speculation and C the highest degree of speculation.  For Moody's,  Ba
indicates  the  lowest  degree  of  speculation  and C  the  highest  degree  of
speculation.  While  such debt will  likely  have some  quality  and  protective
characteristics,  these are  outweighed  by large  uncertainties  or major  risk
exposures  to adverse  conditions.  Similarly,  debt rated Ba or BB and below is
regarded by the relevant rating agency as  speculative.  Debt rated C by Moody's
or S&P is the lowest  quality  debt that is not in default  as to  principal  or
interest  and such  issues so rated can be  regarded  as having  extremely  poor
prospects of ever attaining any real  investment  standing.  Such securities are
also  generally  considered  to be subject to greater  risk than higher  quality
securities  with  regard to a  deterioration  of  general  economic  conditions.
Ratings of debt securities represent the rating agency's opinion

                                       16
<PAGE>
regarding  their  quality and are not a guarantee  of quality.  Rating  agencies
attempt to evaluate  the safety of principal  and  interest  payments and do not
evaluate the risks of  fluctuations in market value.  Also,  rating agencies may
fail to make timely changes in credit quality in response to subsequent  events,
so that an issuer's  current  financial  condition may be better or worse than a
rating indicates.

   The market value of lower quality debt securities tend to reflect  individual
developments  of  the  issuer  to  a  greater  extent  than  do  higher  quality
securities,  which react  primarily  to  fluctuations  in the  general  level of
interest  rates.  In addition,  lower  quality debt  securities  tend to be more
sensitive to economic  conditions and generally  have more volatile  prices than
higher quality securities.  Issuers of lower quality securities are often highly
leveraged  and may not  have  available  to them  more  traditional  methods  of
financing.  For example,  during an economic  downturn or a sustained  period of
rising interest rates,  highly leveraged issuers of lower quality securities may
experience  financial  stress.  During such  periods,  such issuers may not have
sufficient  revenues to meet their interest  payment  obligations.  The issuer's
ability  to service  its debt  obligations  may also be  adversely  affected  by
specific  developments  affecting the issuer,  such as the issuer's inability to
meet specific  projected  business forecasts or the unavailability of additional
financing.  Similarly,  certain  emerging  market  governments  that issue lower
quality  debt  securities  are among the largest  debtors to  commercial  banks,
foreign  governments and supranational  organizations such as the World Bank and
may not be able or willing to make principal and/or interest  repayments as they
come due. The risk of loss due to default by the issuer is significantly greater
for the  holders  of  lower  quality  securities  because  such  securities  are
generally unsecured and are often subordinated to other creditors of the issuer.

   Lower quality debt  securities of corporate  issuers  frequently have call or
buy-back  features  which  would  permit  an issuer  to call or  repurchase  the
security from the Fund. If an issuer  exercises these  provisions in a declining
interest  rate market,  the Fund may have to replace the  security  with a lower
yielding security,  resulting in a decreased return for investors.  In addition,
the Fund may have difficulty disposing of lower quality securities because there
may be a thin trading  market for such  securities.  There may be no established
retail secondary market for many of these  securities,  and the Fund anticipates
that  such  securities  could be sold only to a limited  number  of  dealers  or
institutional  investors. The lack of a liquid secondary market also may have an
adverse  impact  on  market  prices  of such  instruments  and may  make it more
difficult  for the Fund to obtain  accurate  market  quotations  for purposes of
valuing the securities in the portfolio of the Fund.

   Adverse  publicity  and  investor  perceptions,   whether  or  not  based  on
fundamental  analysis,  may also  decrease  the  values and  liquidity  of lower
quality  securities,  especially in a thinly traded market.  The High Yield Fund
also may acquire lower quality debt securities during an initial underwriting or
may acquire lower quality debt  securities  which are sold without  registration
under applicable securities laws. Such securities involve special considerations
and risks.

   Factors  having  an  adverse  effect  on the  market  value  of  lower  rated
securities or their equivalents  purchased by the Fund will adversely impact net
asset value of the Fund.  See "Risk Factors" in the  Prospectus.  In addition to
the foregoing,  such factors may include: (i) potential adverse publicity;  (ii)
heightened  sensitivity to general economic or political  conditions;  and (iii)
the likely adverse impact of a major economic recession. The Fund also may incur
additional expenses to the extent it is required to seek recovery upon a default
in the payment of principal or interest on its portfolio holdings,  and the Fund
may have  limited  legal  recourse  in the event of a default.  Debt  securities
issued by  governments  in emerging  markets  can differ  from debt  obligations
issued by private  entities in that  remedies from  defaults  generally  must be
pursued  in the  courts of the  defaulting  government,  and legal  recourse  is
therefore somewhat diminished.  Political conditions, in terms of a government's
willingness to meet the terms of its debt obligations,  also are of considerable
significance. There can be no assurance that the holders of commercial bank debt
may not contest payments to the holders of debt securities issued by governments
in emerging markets in the event of default by the governments  under commercial
bank loan agreements.

   The  Investment  Manager  will  attempt to  minimize  the  speculative  risks
associated with investments in lower quality  securities through credit analyses
and  by  carefully  monitoring  current  trends  in  interest  rates,  political
developments and other factors.  Nonetheless,  investors should carefully review
the  investment  objectives and policies of the Funds and consider their ability
to assume the  investment  risks  involved  before  making an  investment in the
Funds.

   CONVERTIBLE SECURITIES AND WARRANTS.  Certain of the Funds may invest in debt
or preferred  equity  securities  convertible  into or  exchangeable  for equity
securities. Traditionally, convertible securities have paid dividends or

                                       17
<PAGE>
interest  at rates  higher  than  common  stocks but lower  than  nonconvertible
securities.  They generally  participate in the  appreciation or depreciation of
the underlying stock into which they are convertible, but to a lesser degree. In
recent years,  convertibles  have been  developed  which combine higher or lower
current  income with options and other  features.  Warrants are options to buy a
stated number of shares of common stock at a specified price any time during the
life of the warrants (generally two or more years).

   MORTGAGE-BACKED  SECURITIES AND COLLATERALIZED MORTGAGE OBLIGATIONS.  Certain
of the Funds may invest in mortgage-backed securities (MBSs), including mortgage
pass-through  securities and collateralized  mortgage  obligations  (CMOs). MBSs
include certain  securities issued or guaranteed by the United States Government
or one of its agencies or  instrumentalities,  such as the  Government  National
Mortgage  Association (GNMA),  Federal National Mortgage  Association (FNMA), or
Federal Home Loan Mortgage  Corporation  (FHLMC);  securities  issued by private
issuers that represent an interest in or are  collateralized by  mortgage-backed
securities issued or guaranteed by the U.S. Government or one of its agencies or
instrumentalities;  and securities  issued by private  issuers that represent an
interest in or are  collateralized  by mortgage  loans. A mortgage  pass-through
security  is a pro rata  interest  in a pool of  mortgages  where  the cash flow
generated from the mortgage collateral is passed through to the security holder.
CMOs are  obligations  fully  collateralized  by a  portfolio  of  mortgages  or
mortgage-related securities. Certain of the Funds may invest in securities known
as "inverse floating obligations," "residual interest bonds," or "interest-only"
(IO) and "principal-only"  (PO) bonds, the market values of which will generally
be more  volatile  than the  market  values of most MBSs.  An  inverse  floating
obligation is a derivative  adjustable  rate  security with interest  rates that
adjust or vary inversely to changes in market interest rates. The term "residual
interest"  bond is used  generally to describe  those  instruments in collateral
pools,  such as CMOs,  which receive any excess cash flow  generated by the pool
once all other  bondholders and expenses have been paid. IOs and POs are created
by  separating  the  interest  and  principal  payments  generated  by a pool of
mortgage-backed bonds to create two classes of securities.  Generally, one class
receives  interest  only  payments  (IOs) and the  other  class  principal  only
payments  (POs).  MBSs  have  been  referred  to as  "derivatives"  because  the
performance of MBSs is dependent upon and derived from underlying securities.

   CMOs may be issued  in a  variety  of  classes  and the  Funds may  invest in
several  CMO  classes,   including,   but  not  limited  to  Floaters,   Planned
Amortization  Classes (PACs),  Scheduled Classes (SCHs),  Sequential Pay Classes
(SEQs),  Support Classes (SUPs),  Target Amortization Classes (TACs) and Accrual
Classes (Z Classes). CMO classes vary in the rate and time at which they receive
principal and interest payments.  SEQs, also called plain vanilla, clean pay, or
current pay classes,  sequentially  receive  principal  payments from underlying
mortgage  securities  when the principal on a previous class has been completely
paid off. During the months prior to their receipt of principal  payments,  SEQs
receive  interest  payments  at the  coupon  rate on their  principal.  PACs are
designed  to  produce  a  stable  cash  flow  of  principal   payments   over  a
predetermined  period of time.  PACs guard against a certain level of prepayment
risk by distributing  prepayments to SUPs, also called companion  classes.  TACs
pay a targeted  principal payment schedule,  as long as prepayments are not made
at a rate slower than an expected  constant  prepayment  speed.  If  prepayments
increase,  the  excess  over the  target  is paid to SUPs.  SEQs may have a less
stable cash flow than PACs and TACs and, consequently,  have a greater potential
yield.  PACs  generally pay a lower yield than TACs because of PACs' lower risk.
Because  SUPs are  directly  affected by the rate of  prepayment  of  underlying
mortgages,  SUPs may  experience  volatile cash flow behavior.  When  prepayment
speeds  fluctuate,  the average life of a SUP will vary.  SUPs,  therefore,  are
priced at a higher  yield than less  volatile  classes of CMOs. Z Classes do not
receive payments,  including interest payments,  until certain other classes are
paid off. At that time, the Z Class begins to receive the  accumulated  interest
and principal  payments.  A Floater has a coupon rate that adjusts  periodically
(usually  monthly) by adding a spread to a benchmark index subject to a lifetime
maximum cap. The yield of a Floater is  sensitive  to  prepayment  rates and the
level of the benchmark index.

   Investment  in MBSs poses several  risks,  including  prepayment,  market and
credit  risks.  Prepayment  risk  reflects the chance that  borrowers may prepay
their mortgages faster than expected, thereby affecting the investment's average
life and  perhaps  its  yield.  Borrowers  are most  likely  to  exercise  their
prepayment  options  at a time  when  it is  least  advantageous  to  investors,
generally  prepaying  mortgages as interest rates fall, and slowing  payments as
interest rates rise.  Certain classes of CMOs may have priority over others with
respect to the receipt of  prepayments  on the mortgages and the Fund may invest
in CMOs which are subject to greater  risk of  prepayment  as  discussed  above.
Market risk  reflects the chance that the price of the  security  may  fluctuate
over  time.  The  price  of MBSs may be  particularly  sensitive  to  prevailing
interest rates, the length of time the security is

                                       18
<PAGE>
expected  to be  outstanding  and the  liquidity  of the  issue.  In a period of
unstable  interest  rates,  there may be decreased  demand for certain  types of
MBSs,  and a Fund invested in such  securities  wishing to sell them may find it
difficult  to find a buyer,  which may in turn  decrease the price at which they
may be sold.  Credit risk  reflects the chance that the Fund may not receive all
or part of its principal  because the issuer or credit enhancer has defaulted on
its  obligations.  Obligations  issued by U.S.  Government-related  entities are
guaranteed  by  the  agency  or   instrumentality,   and  some,   such  as  GNMA
certificates,  are supported by the full faith and credit of the U.S.  Treasury;
others are  supported  by the right of the issuer to borrow  from the  Treasury;
others, such as those of the FNMA, are supported by the discretionary  authority
of the U.S. Government to purchase the agency's  obligations;  still others, are
supported only by the credit of the instrumentality.  Although securities issued
by U.S.  Government-related  agencies are guaranteed by the U.S. Government, its
agencies or  instrumentalities,  shares of the Fund are not so guaranteed in any
way. The performance of private label MBSs, issued by private  institutions,  is
based on the financial health of those institutions.

   ASSET-BACKED   SECURITIES.   Certain   of  the  Funds  may  also   invest  in
"asset-backed  securities."  These include  secured debt  instruments  backed by
automobile  loans,  credit card loans, home equity loans,  manufactured  housing
loans and other types of secured loans  providing  the source of both  principal
and  interest.  Asset-backed  securities  are subject to risks  similar to those
discussed above with respect to MBSs.

   WHEN-ISSUED  AND  FORWARD  COMMITMENT  SECURITIES.  Certain  of the Funds may
purchase securities on a "when-issued" basis and may purchase or sell securities
on a "forward commitment" basis in order to hedge against anticipated changes in
interest  rates and prices.  The price,  which is  generally  expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities  take place at a later date.  When-issued  securities and forward
commitments  may be sold prior to the settlement  date, but the Funds will enter
into  when-issued  and forward  commitments  only with the intention of actually
receiving or delivering the securities, as the case may be. No income accrues on
securities  which have been purchased  pursuant to a forward  commitment or on a
when-issued basis prior to delivery of the securities. If a Fund disposes of the
right to acquire a when-issued  security prior to its acquisition or disposes of
its right to  deliver or receive  against a forward  commitment,  it may incur a
gain or loss. At the time a Fund enters into a transaction  on a when-issued  or
forward  commitment  basis,  a segregated  account  consisting of cash or liquid
securities  equal  to  the  value  of  the  when-issued  or  forward  commitment
securities  will be established  and  maintained  with its custodian and will be
marked to market daily. There is a risk that the securities may not be delivered
and that the Fund may incur a loss.

DERIVATIVE INSTRUMENTS:  OPTIONS AND FUTURES STRATEGIES

   WRITING  COVERED CALL OPTIONS.  Certain of the Funds may write (sell) covered
call options.  Covered call options  generally will be written on securities and
currencies  which, in the opinion of the Investment  Manager are not expected to
make any major price moves in the near future but which, over the long term, are
deemed to be attractive investments.

   A call  option  gives the holder  (buyer) the right to purchase a security or
currency at a specified  price (the exercise  price) at any time until a certain
date (the  expiration  date).  So long as the obligation of the writer of a call
option  continues,  he may be assigned an exercise  notice by the  broker/dealer
through  whom such  option was sold,  requiring  him to deliver  the  underlying
security or currency  against  payment of the exercise  price.  This  obligation
terminates upon the expiration of the call option, or such earlier time at which
the  writer  effects a closing  purchase  transaction  by  purchasing  an option
identical to that previously sold. The Investment  Manager believes that writing
covered call options is less risky than  writing  uncovered or "naked"  options,
which the Funds will not do.

   Portfolio  securities  on which call options may be written will be purchased
solely on the basis of  investment  considerations  consistent  with that Fund's
investment  objectives.  When writing a covered call option,  the Fund in return
for the premium gives up the opportunity for profit from a price increase in the
underlying  security  above the  exercise  price,  and  retains the risk of loss
should the price of the security  decline.  Unlike one who owns  securities  not
subject to an option, a Fund has no control over when it may be required to sell
the underlying  securities,  since the option may be exercised at any time prior
to the option's  expiration.  If a call option which a Fund has written expires,
the Fund will  realize a gain in the amount of the premium;  however,  such gain
may be offset by a decline in the market value of the underlying security during
the option period.  If the call option is exercised,  a Fund will realize a gain
or loss from the sale of the underlying security.

                                       19
<PAGE>
   The  premium  which a Fund  receives  for  writing a call option is deemed to
constitute the market value of an option. The premium the Fund will receive from
writing a call option will reflect, among other things, the current market price
of the  underlying  security,  the  relationship  of the exercise  price to such
market price, the historical price  volatility of the underlying  security,  and
the length of the option period. In determining whether a particular call option
should be written on a particular security, the Investment Manager will consider
the  reasonableness of the anticipated  premium and the likelihood that a liquid
secondary  market will exist for those options.  The premium  received by a Fund
for writing  covered  call options will be recorded as a liability in the Fund's
statement of assets and  liabilities.  This  liability will be adjusted daily to
the option's  current market value,  which will be the latest sales price at the
time which the net asset value per share of the Fund is computed at the close of
regular trading on the NYSE (currently,  3:00 p.m. Central time, unless weather,
equipment  failure or other factors  contribute to an earlier closing time), or,
in the absence of such sale,  the latest  asked  price.  The  liability  will be
extinguished upon expiration of the option,  the purchase of an identical option
in a closing  transaction,  or  delivery  of the  underlying  security  upon the
exercise of the option.

   Closing  transactions  will be  effected  in order to  realize a profit on an
outstanding call option, to prevent an underlying security from being called, or
to permit the sale of the underlying security. Furthermore,  effecting a closing
transaction  will permit a Fund to write  another call option on the  underlying
security with either a different exercise price, expiration date or both. If the
Fund desires to sell a particular  security  from its  portfolio on which it has
written a call  option,  or  purchased  a put  option,  it will seek to effect a
closing  transaction  prior to, or concurrently  with, the sale of the security.
There  is no  assurance  that  the  Fund  will be able to  effect  such  closing
transactions  at  favorable  prices.  If  the  Fund  cannot  enter  into  such a
transaction,  it may be required to hold a security that it might otherwise have
sold,  in which case it would  continue to be at market risk with respect to the
security.

   The Fund will pay transaction costs in connection with the writing of options
and in entering into closing purchase  contracts.  Transaction costs relating to
options  activity  normally are higher than those  applicable  to purchases  and
sales of portfolio securities.

   Call options written by the Fund normally will have expiration  dates of less
than nine months from the date written. The exercise price of the options may be
below, equal to or above the current market values of the underlying  securities
at the time the options are written. From time to time, the Fund may purchase an
underlying  security for delivery in accordance  with the exercise of an option,
rather  than  delivering  such  security  from  its  portfolio.  In such  cases,
additional costs will be incurred.

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

   WRITING  COVERED  PUT  OPTIONS.  Certain of the Funds may write  covered  put
options.  A put option gives the purchaser of the option the right to sell,  and
the writer  (seller)  the  obligation  to buy,  the  underlying  security at the
exercise price during the option period. The option may be exercised at any time
prior to its expiration  date.  The operation of put options in other  respects,
including their related risks and rewards, is substantially identical to that of
call options.

   The Fund would write put options  only on a covered  basis,  which means that
the Fund would either (i) set aside cash or liquid  securities  in an amount not
less than the  exercise  price at all times while the put option is  outstanding
(the rules of the  Options  Clearing  Corporation  currently  require  that such
assets be deposited in escrow to secure  payment of the  exercise  price),  (ii)
sell short the  security  underlying  the put option at the same or higher price
than the exercise price of the put option,  or (iii)  purchase a put option,  if
the exercise  price of the  purchased  put option is the same or higher than the
exercise  price of the put option  sold by the Fund.  The Fund  generally  would
write covered put options in circumstances  where the Investment  Manager wishes
to purchase the  underlying  security for the Fund's  portfolio at a price lower
than the current  market price of the  security.  In such event,  the Fund would
write a put option at an exercise price which,  reduced by the premium  received
on the option,  reflects  the lower  price it is willing to pay.  Since the Fund
also would receive interest on debt securities  maintained to cover the exercise
price of the option,  this  technique  could be used to enhance  current  return
during periods of market  uncertainty.  The risk in such a transaction  would be
that the  market  price of the  underlying  security  would  decline  below  the
exercise price less the premiums received.

                                       20
<PAGE>
   PURCHASING PUT OPTIONS. Certain of the Funds may purchase put options. As the
holder of a put  option,  the Fund would  have the right to sell the  underlying
security at the exercise  price at any time during the option  period.  The Fund
may enter into closing sale transactions with respect to such options,  exercise
them or permit them to expire.

   The Fund may  purchase a put option on an  underlying  security  ("protective
put") owned by the Fund as a hedging  technique  in order to protect  against an
anticipated  decline  in the value of the  security.  Such hedge  protection  is
provided  only during the life of the put option when the Fund, as the holder of
the put option,  is able to sell the  underlying  security  at the put  exercise
price regardless of any decline in the underlying  security's  market price. For
example,  a  put  option  may  be  purchased  in  order  to  protect  unrealized
appreciation  of a security  when the  Investment  Manager deems it desirable to
continue to hold the security  because of tax  considerations.  The premium paid
for the put option and any  transaction  costs  would  reduce any  capital  gain
otherwise available for distribution when the security eventually is sold.

   Certain  Funds also may purchase put options at a time when the Fund does not
own the underlying security. By purchasing put options on a security it does not
own,  the Fund  seeks to  benefit  from a  decline  in the  market  price of the
underlying security.  If the put option is not sold when it has remaining value,
and if the market price of the underlying  security  remains equal to or greater
than the exercise  price  during the life of the put option,  the Fund will lose
its entire  investment  in the put  option.  In order for the  purchase of a put
option to be  profitable,  the  market  price of the  underlying  security  must
decline  sufficiently  below  the  exercise  price  to  cover  the  premium  and
transaction cost, unless the put option is sold in a closing sale transaction.

   The premium paid by the Fund when purchasing a put option will be recorded as
an asset in the Fund's statement of assets and  liabilities.  This asset will be
adjusted daily to the option's  current  market value,  which will be the latest
sale  price at the time at which  the net  asset  value per share of the Fund is
computed  (at the close of regular  trading on the NYSE),  or, in the absence of
such sale, the latest bid price. The asset will be extinguished  upon expiration
of the option, the writing of an identical option in a closing  transaction,  or
the delivery of the underlying security upon the exercise of the option.

   PURCHASING  CALL OPTIONS.  Certain  Funds may purchase  call options.  As the
holder  of a call  option,  the Fund  would  have  the  right  to  purchase  the
underlying  security at the exercise price at any time during the option period.
The Fund may enter into closing sale  transactions with respect to such options,
exercise  them or permit them to expire.  Call  options may be  purchased by the
Fund for the purpose of acquiring  the  underlying  security for its  portfolio.
Utilized in this fashion,  the purchase of call options would enable the Fund to
acquire the security at the  exercise  price of the call option plus the premium
paid.  At times,  the net cost of  acquiring  the security in this manner may be
less than the cost of acquiring the security  directly.  This technique also may
be useful to a Fund in purchasing a large block of securities that would be more
difficult to acquire by direct market purchases. So long as it holds such a call
option  rather  than the  underlying  security  itself,  the  Fund is  partially
protected  from any  unexpected  decline in the market  price of the  underlying
security  and in such event could  allow the call option to expire,  incurring a
loss only to the extent of the premium paid for the option.

   The Fund also may purchase call options on  underlying  securities it owns in
order to protect  unrealized gains on call options  previously  written by it. A
call option would be purchased for this purpose where tax considerations make it
inadvisable to realize such gains through a closing purchase  transaction.  Call
options  also may be  purchased  at times to avoid  realizing  losses that would
result in a reduction of the Fund's current  return.  For example,  the Fund has
written a call option on an underlying  security  having a current  market value
below the price at which such security was purchased by the Fund, an increase in
the market price could result in the exercise of the call option  written by the
Fund and the  realization  of a loss on the  underlying  security  with the same
exercise price and expiration date as the option previously written.

   Aggregate  premiums  paid for put and call  options will not exceed 5% of the
Fund's total assets at the time of purchase.

   INTEREST RATE FUTURES  CONTRACTS.  Certain Funds may enter into interest rate
futures contracts  ("Futures" or "Futures Contracts") as a hedge against changes
in prevailing  levels of interest  rates.  A Fund's hedging may include sales of
Futures as an offset against the effect of expected increases in interest rates,
and purchases of Futures as an offset against the effect of expected declines in
interest rates.

   The Funds will not enter into Futures Contracts for speculation and will only
enter into Futures  Contracts which are traded on national futures exchanges and
are standardized as to maturity date and underlying  financial  instrument.  The
principal interest rate exchanges in the United States are the Board of Trade of
the City of

                                       21
<PAGE>
Chicago and the Chicago Mercantile  Exchange.  Futures exchanges and trading are
regulated  under the  Commodity  Exchange Act by the Commodity  Futures  Trading
Commission ("CFTC"). Futures are exchanged in London at the London International
Financial Futures Exchange.

   Although techniques other than sales and purchases of Futures Contracts could
be used to reduce a Fund's exposure to interest rate fluctuations,  the Fund may
be able to hedge  exposure  more  effectively  and at a lower cost through using
Futures Contracts.

   The Fund will not enter into a Futures Contract if, as a result thereof, more
than 5% of the  Fund's  total  assets  (taken  at  market  value  at the time of
entering  into the  contract)  would be  committed  to "margin"  (down  payment)
deposits on such Futures Contracts.

   A Futures Contract  provides for the future sale by one party and purchase by
another party of a specified  amount of a specific  financial  instrument  (debt
security) for a specified price at a designated date, time and place.  Brokerage
fees are incurred when a Futures Contract is bought or sold, and margin deposits
must be maintained at all times the Futures Contract is outstanding.

   Although Futures  Contracts  typically require future delivery of and payment
for financial  instruments,  Futures Contracts usually are closed out before the
delivery date. Closing out an open Futures Contract sale or purchase is effected
by entering into an offsetting Futures Contract purchase or sale,  respectively,
for the same aggregate amount of the identical financial instrument and the same
delivery date. If the  offsetting  purchase price is less than the original sale
price,  the Fund  realizes  a gain;  if it is more,  the Fund  realizes  a loss.
Conversely,  if the  offsetting  sale price is more than the  original  purchase
price,  the Fund realizes a gain; if it is less,  the Fund realizes a loss.  The
transaction costs also must be included in these  calculations.  There can be no
assurance,  however,  that the Fund  will be able to  enter  into an  offsetting
transaction with respect to a particular  Futures Contract at a particular time.
If the Fund is not able to enter into an offsetting  transaction,  the Fund will
continue to be required to maintain the margin deposits on the Futures Contract.

   Persons who trade in Futures Contracts may be broadly classified as "hedgers"
and "speculators."  Hedgers, such as the Funds, whose business activity involves
investment  or other  commitment in  securities  or other  obligations,  use the
Futures markets primarily to offset unfavorable  changes in value that may occur
because of fluctuations  in the value of the securities and obligations  held or
expected to be acquired by them.  Debtors and other  obligors also may hedge the
interest cost of their obligations.  The speculator,  like the hedger, generally
expects  neither to deliver nor to receive the financial  instrument  underlying
the Futures Contract,  but, unlike the hedger, hopes to profit from fluctuations
in prevailing interest rates.

   The Fund's Futures  transactions will be entered into for traditional hedging
purposes;  that is, Futures  Contracts will be sold to protect against a decline
in the price of  securities  that the Fund owns,  or Futures  Contracts  will be
purchased to protect the Fund against an increase in the price of  securities it
has committed to purchase or expects to purchase.

   "Margin"  with respect to Futures  Contracts is the amount of funds that must
be deposited by the Fund, in a segregated account with the Fund's custodian,  in
order to initiate  Futures  trading and to maintain the Fund's open positions in
Futures  Contracts.  A margin deposit made when the Futures  Contract is entered
into  ("initial  margin") is intended  to assure the Fund's  performance  of the
Futures Contract.  The margin required for a particular  Futures Contract is set
by the  exchange  on which the Futures  Contract is traded,  and may be modified
significantly  from time to time by the exchange  during the term of the Futures
Contract.  Futures Contracts  customarily are purchased and sold on margins that
may range  upward from less than 5% of the value of the Futures  Contract  being
traded.

   If the price of an open Futures  Contract changes (by increase in the case of
a sale or by decrease in the case of a purchase) so that the loss on the Futures
Contract  reaches a point at which the margin on deposit does not satisfy margin
requirements, the broker will require an increase in the margin deposit ("margin
variation").  If the value of a position  increases  because of favorable  price
changes in the Futures  Contract so that the margin deposit exceeds the required
margin,  however, the broker will pay the excess to the Fund. In computing daily
net asset  values,  the Fund will mark to market the  current  value of its open
Futures  Contracts.  The Fund  expects  to earn  interest  income on its  margin
deposits.
   
   MUNICIPAL  BOND INDEX FUTURES  CONTRACTS.  The Municipal  Bond Fund may enter
into  municipal  bond index futures  contracts.  A municipal  bond index futures
contract is an agreement to take or make  delivery of an amount of cash equal to
the difference between the value of the index at the beginning and at the end of
the contract period. In a substantial  majority of these transactions,  the Fund
will purchase such securities upon

                                       22
<PAGE>
termination  of the futures  position but, under unusual  market  conditions,  a
futures  position  may be  terminated  without  the  corresponding  purchase  of
securities.
    
   RISKS OF USING  FUTURES  CONTRACTS.  The  prices  of  Futures  Contracts  are
volatile  and are  influenced,  among other  things,  by actual and  anticipated
changes in interest  rates,  which in turn are  affected by fiscal and  monetary
policies and national and international political and economic events.

   There is a risk of imperfect correlation between changes in prices of Futures
Contracts and prices of the securities in the Fund's portfolio being hedged. The
degree of  imperfection  of  correlation  depends  upon  circumstances  such as:
variations in  speculative  market  demand for Futures and for debt  securities,
including technical  influences in Futures trading;  and differences between the
financial  instruments being hedged and the instruments  underlying the standard
Futures Contracts  available for trading,  with respect to interest rate levels,
maturities,  and  creditworthiness of issuers. A decision of whether,  when, and
how to hedge involves skill and judgment, and even a well-conceived hedge may be
unsuccessful  to some degree because of unexpected  market  behavior or interest
rate trends.

   Because of the low margin  deposits  required,  Futures  trading  involves an
extremely  high  degree of  leverage.  As a result,  a  relatively  small  price
movement in a Futures Contract may result in immediate and substantial  loss, as
well as gain, to the investor.  For example, if at the time of purchase,  10% of
the value of the Futures  Contract is  deposited  as margin,  a  subsequent  10%
decrease in the value of the Futures  Contract  would  result in a total loss of
the margin  deposit,  before any deduction  for the  transaction  costs,  if the
account were then closed out. A 15%  decrease  would result in a loss of 150% of
the original margin  deposit,  if the Contract were closed out. Thus, a purchase
or sale of a Futures  Contract  may  result  in  losses in excess of the  amount
invested  in the  Futures  Contract.  However,  the Fund  presumably  would have
sustained comparable losses if, instead of the Futures Contract, it had invested
in the underlying financial instrument and sold it after the decline.

   Furthermore,  in the  case of a  Futures  Contract  purchase,  in order to be
certain that the Fund has sufficient  assets to satisfy its obligations  under a
Futures  Contract,  the Fund sets aside and commits to back the Futures Contract
an amount of cash and liquid  securities  equal in value to the current value of
the underlying instrument less margin deposit.

   In the case of a  Futures  contract  sale,  the Fund  either  will set  aside
amounts,  as in the  case of a  Futures  Contract  purchase,  own  the  security
underlying  the contract or hold a call option  permitting  the Fund to purchase
the same Futures  Contract at a price no higher than the contract price.  Assets
used as cover  cannot be sold while the  position in the  corresponding  Futures
Contract is open, unless they are replaced with similar assets. As a result, the
commitment of a  significant  portion of the Fund's assets to cover could impede
portfolio  management or the Fund's ability to meet redemption requests or other
current obligations.

   Most U.S.  Futures  exchanges  limit the amount of  fluctuation  permitted in
Futures Contract prices during a single trading day. The daily limit establishes
the maximum  amount that the price of a Futures  Contract  may vary either up or
down from the previous day's  settlement  price at the end of a trading session.
Once the daily limit has been reached in a particular type of Futures  Contract,
no trades may be made on that day at a price beyond that limit.  The daily limit
governs only price movement  during a particular  trading day and therefore does
not limit  potential  losses,  because the limit may prevent the  liquidation of
unfavorable  positions.  Futures Contract prices  occasionally have moved to the
daily  limit for  several  consecutive  trading  days with little or no trading,
thereby  preventing prompt  liquidation of Futures positions and subjecting some
Futures traders to substantial losses.

   OPTIONS ON FUTURES  CONTRACTS.  Options on Futures  Contracts  are similar to
options  on  securities  except  that  options  on  Futures  Contracts  give the
purchaser  the right,  in return for the premium paid, to assume a position in a
Futures  Contract (a long position if the option is a call and a short  position
if the option is a put),  rather than to purchase or sell the Futures  Contract,
at a specified exercise price at any time during the period of the option.  Upon
exercise of the option,  the  delivery of the Futures  position by the writer of
the option to the holder of the option  will be  accompanied  by delivery of the
accumulated  balance in the writer's Futures margin account which represents the
amount by which the market price of the Futures Contract,  at exercise,  exceeds
(in the  case of a call) or is less  than  (in the  case of a put) the  exercise
price of the option on the Futures  Contract.  If an option is  exercised on the
last trading day prior to the expiration date of the option, the settlement will
be made entirely in cash equal to the  difference  between the exercise price of
the  option  and the  closing  level of the  securities  or index upon which the
Futures  Contracts are based on the expiration  date.  Purchasers of options who
fail to exercise  their  options prior to the exercise date suffer a loss of the
premium paid.

                                       23
<PAGE>
   As an alternative to purchasing call and put options on Futures, the Fund may
purchase  call and put options on the  underlying  securities  themselves.  Such
options  would be used in a manner  identical  to the use of  options on Futures
Contracts.

   To reduce or eliminate  the leverage  then employed by the Fund, or to reduce
or eliminate the hedge  position then  currently  held by the Fund, the Fund may
seek to close out an option  position  by  selling an option  covering  the same
securities or contract and having the same exercise price and  expiration  date.
Trading in options on Futures Contracts began relatively  recently.  The ability
to  establish  and close out  positions  on such  options will be subject to the
development and maintenance of a liquid secondary market. It is not certain that
this market will develop.

   INTEREST RATE AND CURRENCY SWAPS. The High Yield Fund may enter into interest
rate and index  swaps and the  purchase  or sale of  related  caps,  floors  and
collars.  The Fund usually will enter into interest rate swaps on a net basis if
the contract so provides,  that is, the two payment  streams are netted out in a
cash settlement on the payment date or dates  specified in the instrument,  with
the Fund receiving or paying, as the case may be, only the net amount of the two
payments.  Inasmuch as swaps, caps, floors and collars are entered into for good
faith hedging purposes,  the Fund and the Investment Manager,  believe that they
do not constitute senior securities under the 1940 Act if appropriately  covered
and,  thus,  will  not  treat  them as being  subject  to the  Fund's  borrowing
restrictions. The Fund will not enter into any swap, cap, floor, collar or other
derivative transaction unless, at the time of entering into the transaction, the
unsecured  long-term  debt rating of the  counterparty  combined with any credit
enhancements  is rated at least A by Moody's or S&P or has an equivalent  rating
from a nationally recognized statistical rating organization or is determined to
be of equivalent  credit  quality by the Investment  Manager.  If a counterparty
defaults,  the Fund may have  contractual  remedies  pursuant to the  agreements
related to the transactions.  The swap market has grown  substantially in recent
years, with a large number of banks and investment  banking firms acting both as
principals and as agents utilizing standardized swap documentation. As a result,
the swap market has become relatively liquid.  Caps, floors and collars are more
recent innovations for which  standardized  documentation has not yet been fully
developed and, for that reason, they are less liquid than swaps.

   EMERGING  COUNTRIES.  Certain of the Funds may invest in debt  securities  in
emerging  markets.  Investing in  securities  in emerging  countries  may entail
greater risks than investing in debt  securities in developed  countries.  These
risks include (i) less social, political and economic stability;  (ii) the small
current  size of the  markets  for  such  securities  and the  currently  low or
nonexistent  volume  of  trading,  which  result in a lack of  liquidity  and in
greater price volatility; (iii) certain national policies which may restrict the
Fund's investment opportunities, including restrictions on investment in issuers
or industries deemed sensitive to national interests; (iv) foreign taxation; and
(v) the absence of developed  structures governing private or foreign investment
or allowing for judicial redress for injury to private property.

   FOREIGN  INVESTMENT  RESTRICTIONS.   Certain  countries  prohibit  or  impose
substantial  restrictions on investments in their capital markets,  particularly
their equity markets,  by foreign entities such as the Funds. As  illustrations,
certain countries require governmental  approval prior to investments by foreign
persons,  or limit the amount of investment  by foreign  persons in a particular
company, or limit the investments by foreign persons to only a specific class of
securities of a company that may have less advantageous terms than securities of
the company available for purchase by nationals. Moreover, the national policies
of  certain  countries  may  restrict  investment  opportunities  in  issuers or
industries deemed sensitive to national interests.  In addition,  some countries
require governmental approval for the repatriation of investment income, capital
or the  proceeds  of  securities  sales by  foreign  investors.  A Fund could be
adversely   affected  by  delays  in,  or  a  refusal  to  grant,  any  required
governmental  approval for repatriation,  as well as by the application to it of
other restrictions on investments.

   POLITICAL AND ECONOMIC RISKS.  Investing in securities of non-U.S.  companies
may  entail  additional  risks  due  to the  potential  political  and  economic
instability   of   certain   countries   and   the   risks   of   expropriation,
nationalization,  confiscation  or the  imposition  of  restrictions  on foreign
investment  and on  repatriation  of  capital  invested.  In the  event  of such
expropriation,  nationalization  or other  confiscation  by any country,  a Fund
could lose its entire investment in any such country.

   An investment in a Fund which invests in non-U.S. companies is subject to the
political and economic risks  associated  with  investments in foreign  markets.
Even though  opportunities  for  investment may exist in emerging  markets,  any
change in the leadership or policies of the governments of those countries or in
the leadership or

                                       24
<PAGE>
policies of any other  government  which exercises a significant  influence over
those  countries,  may halt the  expansion of or reverse the  liberalization  of
foreign  investment  policies now occurring and thereby eliminate any investment
opportunities which may currently exist.

   Investors  should  note that  upon the  accession  to power of  authoritarian
regimes,  the  governments of a number of emerging market  countries  previously
expropriated  large  quantities  of real and  personal  property  similar to the
property which will be  represented  by the securities  purchased by a Fund. The
claims of property owners against those  governments were never finally settled.
There can be no assurance that any property  represented by securities purchased
by a Fund will not also be expropriated, nationalized, or otherwise confiscated.
If such confiscation were to occur, the Fund could lose a substantial portion of
its investments in such  countries.  The Fund's  investments  would similarly be
adversely affected by exchange control regulation in any of those countries.

   RELIGIOUS  AND  ETHNIC  INSTABILITY.  Certain  countries  in which a Fund may
invest  may  have  vocal   minorities   that  advocate   radical   religious  or
revolutionary  philosophies or support ethnic  independence.  Any disturbance on
the  part  of  such  individuals  could  carry  the  potential  for  wide-spread
destruction  or  confiscation  of property  owned by  individuals  and  entities
foreign to such  country  and could cause the loss of the Fund's  investment  in
those countries.

   NON-UNIFORM  CORPORATE  DISCLOSURE  STANDARDS  AND  GOVERNMENTAL  REGULATION.
Foreign  companies are subject to accounting,  auditing and financial  standards
and requirements that differ, in some cases significantly, from those applicable
to U.S. companies. In particular,  the assets, liabilities and profits appearing
on the  financial  statements  of such a company may not  reflect its  financial
position or results of  operations  in the way they would be reflected  had such
financial  statements been prepared in accordance with U.S.  generally  accepted
accounting principles. Most of the foreign securities held by a Fund will not be
registered  with the SEC or  regulators  of any  foreign  country,  nor will the
issuers thereof be subject to the SEC's reporting requirements. Thus, there will
be less available  information  concerning foreign issuers of securities held by
the Fund than is available  concerning  U.S.  issuers.  In  instances  where the
financial  statements  of an issuer  are not deemed to  reflect  accurately  the
financial   situation  of  the  issuer,  the  Investment  Manager  and  relevant
Sub-Adviser  will take  appropriate  steps to evaluate the proposed  investment,
which  may  include  on-site  inspection  of the  issuer,  interviews  with  its
management and consultations  with accountants,  bankers and other  specialists.
There  is  substantially  less  publicly  available  information  about  foreign
companies than there are reports and ratings published about U.S.  companies and
the U.S. Government.  In addition, where public information is available, it may
be less reliable than such information regarding U.S. issuers.

   ADVERSE  MARKET  CHARACTERISTICS.  Securities of many foreign  issuers may be
less liquid and their prices more  volatile than  securities of comparable  U.S.
issuers.  In addition,  foreign  securities  exchanges and brokers generally are
subject to less  governmental  supervision  and regulation than in the U.S., and
foreign  securities   exchange   transactions   usually  are  subject  to  fixed
commissions,  which  generally are higher than  negotiated  commissions  on U.S.
transactions.  In addition,  foreign  securities  exchange  transactions  may be
subject to  difficulties  associated  with the settlement of such  transactions.
Delays in settlement  could result in temporary  periods when assets of the Fund
are  uninvested  and no return is earned  thereon.  The inability of the Fund to
make intended  security  purchases due to settlement  problems could cause it to
miss attractive opportunities.  Inability to dispose of a portfolio security due
to  settlement  problems  either  could  result  in  losses  to the  Fund due to
subsequent  declines  in value of the  portfolio  security  or,  if the Fund has
entered into a contract to sell the security, could result in possible liability
to the purchaser.  The Investment  Manager will consider such  difficulties when
determining the allocation of the Fund's assets.

   NON-U.S. WITHHOLDING TAXES. A Fund's investment income and gains from foreign
issuers may be subject to non-U.S. withholding and other taxes, thereby reducing
the Fund's investment income and gains.

   COSTS.  Investors should  understand that the expense ratio of the Funds that
invest in  foreign  securities  can be  expected  to be higher  than  investment
companies  investing in domestic  securities  since the cost of maintaining  the
custody of foreign  securities  and the rate of advisory  fees paid by the Funds
are higher.

   EASTERN  EUROPE.  Changes  occurring in Eastern Europe and Russia today could
have long-term potential  consequences.  As restrictions fail, this could result
in rising  standards of living,  lower  manufacturing  costs,  growing  consumer
spending, and substantial economic growth. However,  investment in the countries
of Eastern Europe and Russia is highly  speculative at this time.  Political and
economic  reforms  are too  recent  to  establish  a  definite  trend  away from
centrally-planned economies and state owned industries. In many of the countries
of Eastern  Europe and Russia,  there is no stock  exchange or formal market for
securities. Such countries may also

                                       25
<PAGE>
have government exchange controls,  currencies with no recognizable market value
relative to the established currencies of western market economies, little or no
experience in trading in securities, no financial reporting standards, a lack of
a banking and  securities  infrastructure  to handle such  trading,  and a legal
tradition  which does not  recognize  rights in private  property.  In addition,
these  countries  may have  national  policies  which  restrict  investments  in
companies  deemed sensitive to the country's  national  interest.  Further,  the
governments in such  countries may require  governmental  or  quasi-governmental
authorities to act as custodian of the Fund's assets  invested in such countries
and  these  authorities  may  not  qualify  as a  foreign  custodian  under  the
Investment  Company  Act of 1940  and  exemptive  relief  from  such  Act may be
required.  All of these  considerations  are among the factors which could cause
significant risks and uncertainties to investment in Eastern Europe and Russia.

   AMERICAN  DEPOSITARY RECEIPTS (ADRS). The High Yield Fund may invest in ADRs.
ADRs are  dollar-denominated  receipts issued  generally by U.S. banks and which
represent the deposit with the bank of a foreign company's securities.  ADRs are
publicly traded on exchanges or over-the-counter in the United States. Investors
should  consider  carefully  the  substantial  risks  involved in  investing  in
securities issued by companies of foreign nations,  which are in addition to the
usual  risks  inherent  in  domestic   investments.   See  "Foreign   Investment
Restrictions," above.

INVESTMENT POLICY LIMITATIONS

   Each of the  Funds  operate  within  certain  fundamental  investment  policy
limitations. These limitations may not be changed for the Funds without approval
of the lesser of (i) 67% or more of the voting  securities  present at a meeting
if the holders of more than 50% of the  outstanding  voting  securities  of that
Fund  are  present  or  represented  by  proxy,  or (ii)  more  than  50% of the
outstanding voting securities of that Fund.

INCOME FUND'S FUNDAMENTAL POLICIES

   The fundamental  investment policies of the Income Fund, which are applicable
to each of the Corporate Bond,  Limited Maturity Bond, U.S.  Government and High
Yield Funds are:

 1.  Not to  invest in  companies  having a record  of less  than  three  years'
     continuous  operation,  which may include  the  operations  of  predecessor
     companies; provided, however, that this investment policy does not apply to
     the High Yield Fund.

 2.  Not to invest in the  securities of an issuer if the officers and directors
     of the  Fund,  Underwriter  or  Manager  own  more  than  1/2 of 1% of such
     securities  or if all  such  persons  together  own  more  than  5% of such
     securities.

 3.  Not to invest  more  than 5% of its  assets  in the  securities  of any one
     issuer  (other than  securities  of the U.S.  Government,  its  agencies or
     instrumentalities);  provided,  however, that for the High Yield Fund, this
     limitation  applies  only  with  respect  to 75% of the  value of its total
     assets.

 4.  Not to purchase more than 10% of the outstanding  voting  securities (or of
     any  class  of  outstanding  securities)  of any  one  issuer  (other  than
     securities of the U.S. Government, its agencies or instrumentalities).

 5.  Not to invest  in  companies  for the  purpose  of  exercising  control  of
     management.

 6.  Not to act as underwriter of securities of other issuers.

 7.  Not to  invest in an amount  equal  to, or in excess  of,  25% of its total
     assets  in any  particular  industry  (other  than  securities  of the U.S.
     Government, its agencies or instrumentalities).

 8.  Not to purchase or sell real  estate.  (This  policy  shall not prevent the
     Fund from  investing  in  securities  or other  instruments  backed by real
     estate or in securities of companies engaged in the real estate business.)

 9.  Not to buy or sell commodities or commodity contracts;  provided,  however,
     that the Funds  may,  to the  extent  appropriate  under  their  investment
     programs,  purchase securities of companies engaged in such activities, may
     enter into  transactions in financial futures contracts and related options
     for  hedging  purposes,  may engage in  transactions  on a  when-issued  or
     forward commitment basis and may enter into forward currency contracts.

10.  Not to make loans to other  persons other than for the purchase of publicly
     distributed  debt  securities and U.S.  Government  obligations or by entry
     into  repurchase  agreements;   provided,  however,  that  this  investment
     limitation does not apply to the High Yield Fund.

11.  Not to  invest  its  assets  in puts,  calls,  straddles,  spreads,  or any
     combination thereof;  provided,  however,  that this investment policy does
     not apply to High Yield Fund.

                                       26
<PAGE>
12.  Not to invest in limited  partnerships  or similar  interests in oil,  gas,
     mineral  lease,  mineral  exploration or  development  programs;  provided,
     however,  that the Fund may invest in the securities of other  corporations
     whose activities include such exploration and development.

13.  With respect to each of the Corporate Bond and U.S.  Government  Funds, not
     to borrow money except for emergency purposes, and then not in excess of 5%
     of its total assets at the time the loan is made. (Any such borrowings will
     be made on a temporary basis from banks and will not be made for investment
     purposes.)  With respect to the Limited  Maturity Bond Fund,  not to borrow
     money in excess  of 10% of its  total  assets at the time the loan is made,
     and then only as a temporary measure for emergency purposes,  to facilitate
     redemption  requests,  or for other  purposes  consistent  with the  Fund's
     investment objectives and policies. With respect to High Yield Fund, not to
     borrow  money,  except  that (a) the Fund may enter  into  certain  futures
     contracts  and  options  related  thereto;  (b) the  Fund  may  enter  into
     commitments to purchase securities in accordance with the Fund's investment
     program,  including delayed delivery and when-issued securities and reverse
     repurchase agreements, and (c) for temporary emergency purposes, High Yield
     Fund may borrow in amounts not  exceeding 33 1/3% of the value of its total
     assets at the time when the loan is made.

14.  Not to  purchase  securities  of any other  investment  company;  provided,
     however  that  Limited  Maturity  Bond  Fund  and the High  Yield  Fund may
     purchase  securities of any  investment  company if in compliance  with the
     Investment Company Act of 1940.

15.  With respect to each of the Corporate Bond and U.S.  Government  Funds, not
     to issue senior securities;  provided,  however, that Limited Maturity Bond
     Fund and the High Yield Fund may issue senior  securities  if in compliance
     with the Investment Company Act of 1940.

16.  With respect to Corporate Bond and U.S.  Government Funds, not to invest in
     restricted  securities  (restricted  securities are securities for which an
     active and  substantial  market  does not exist at the time of  purchase or
     upon  subsequent  valuation,  or for which  there are legal or  contractual
     restrictions as to  disposition);  provided,  however that Limited Maturity
     Bond Fund may  invest in  restricted  securities  if those  securities  are
     eligible for resale to qualified  institutional  investors pursuant to Rule
     144A under the  Securities  Act of 1933; and High Yield Fund may not invest
     more than 15% of its total assets in illiquid securities.

   With respect to Fundamental  Policy (1), the High Yield Fund has entered into
undertakings with the Arizona Securities Department,  pursuant to which the Fund
has agreed to limit the purchase of  securities of issuers in operation for less
than three years ("unseasoned issuers") to 5% of total Fund assets. The Fund may
exceed  the 5%  limit  if,  in the  future,  such  Department  permits  a larger
percentage  of assets to be  invested in  unseasoned  issuers.  With  respect to
Fundamental  Policy  (16),  the High  Yield Fund has  agreed  with the  Arkansas
Securities  Department  to  limit  its  investment  in  securities  which  it is
restricted from selling to the public without  registration under the Securities
Act of 1933 to 10% of Fund assets.  The Fund may invest up to 15% of Fund assets
in such  securities  if the  Arkansas  Department  changes its  position on this
matter in the future or if the Fund's investment  policies,  at some time in the
future, are no longer subject to the jurisdiction of such Department.

   The above limitations, other than those relating to borrowing, are applicable
at the time of  investment,  and later  increases or  decreases  in  percentages
resulting  from  changes in value of net assets will not result in  violation of
such  limitations.  The Fund interprets  Fundamental  Policy (8) to prohibit the
purchase of real estate limited partnerships.
   
MUNICIPAL BOND FUND'S FUNDAMENTAL POLICIES

   Municipal Bond Fund's fundamental investment policies are:
    
 1.  Not to invest  more  than 20% of its  assets  in  securities  which are not
     tax-exempt securities, except for temporary defensive purposes;

 2.  Not to borrow  money,  except that  borrowings  from banks for temporary or
     emergency  purposes  may be made in an amount up to 10% of the Fund's total
     assets at the time the loan is made;

 3.  Not to issue senior securities as defined in the Investment  Company Act of
     1940  except  insofar  as the  Fund may be  deemed  to have  issued  senior
     securities by reason of borrowing money for temporary or emergency purposes
     or purchasing securities on a when-issued or delayed delivery basis;

 4.  Not to  purchase  any  securities  on margin  (except  for such  short-term
     credits  as are  necessary  for the  clearance  of  purchases  and sales of
     portfolio securities) or sell any securities short;

                                       27
<PAGE>
 5.  Not to make loans,  except that this does not  prohibit  the  purchase of a
     portion of an issue of publicly  distributed  bonds,  debentures,  notes or
     other debt securities, or entry into a repurchase agreement;

 6.  Not to engage in the business of  underwriting  securities  issued by other
     persons except to the extent that the Fund may  technically be deemed to be
     an  underwriter  under the Securities Act of 1933 in purchasing and selling
     portfolio securities;
   
 7.  Not to invest in real  estate,  real estate  mortgage  loans,  commodities,
     commodity  futures  contracts or  interests  in oil,  gas or other  mineral
     exploration or development  programs,  provided that this limitation  shall
     not prohibit the purchase of securities issued by companies, including real
     estate investment trusts,  which invest in real estate or interests therein
     nor transactions in financial futures contracts;

 8.  Not to  purchase a  security  if, as a result,  with  respect to 75% of the
     value of the Fund's  total  assets,  more than 5% of the value of its total
     assets  would be  invested  in  securities  of any one issuer  (other  than
     obligations   issued   by   the   U.S.   government,    its   agencies   or
     instrumentalities);
    
 9.  Not to purchase securities of other investment companies, or acquire voting
     securities, except in connection with a merger, consolidation,  acquisition
     or reorganization;

10.  Not to invest more than 25% of its total assets in  securities  the issuers
     of which are in the same  industry.  For purposes of this  limitation,  the
     U.S. government, its agencies or instrumentalities,  and state or municipal
     governments and their political  subdivisions are not considered members of
     any industry;

11.  Not to  pledge,  mortgage  or  hypothecate  its  assets,  except  to secure
     borrowings permitted by fundamental investment policy number (2) above;

12.  Not to write, purchase or sell put or call options or combinations thereof,
     except  that  it may  purchase  and  hold  puts or  "stand-by  commitments"
     relating to municipal securities, as described in this prospectus;
   
13.  Not to invest in securities  which are not readily  marketable,  securities
     the  disposition of which is restricted  under federal  securities  laws or
     repurchase  agreements  maturing  in more  than  seven  days  (collectively
     "illiquid  securities")  if, as a result,  more than 10% of the  Fund's net
     assets would be invested in illiquid securities.
    
   For  purposes  of  restrictions  (8)  and  (10)  above,   each   governmental
subdivision,  i.e.,  state,  territory,  possession  of the United States or any
political subdivision of any of the foregoing, including agencies,  authorities,
instrumentalities,  or similar entities, or of the District of Columbia shall be
considered a separate  issuer if its assets and revenues are separate from those
of the governmental  body creating it and the security is backed only by its own
assets and revenues.  Further, in the case of an industrial development bond, if
the  security  is backed only by the assets and  revenues of a  non-governmental
user, then such  non-governmental  user will be deemed to be the sole issuer. If
an industrial  development bond or government issued security is guaranteed by a
governmental  or other  entity,  such  guarantee  would be considered a separate
security issued by the guarantor.

   The above  limitations  are applicable at the time of  investment,  and later
increases  or decreases in  percentages  resulting  from changes in value or net
assets will not result in violation of such limitations.

CASH FUND'S FUNDAMENTAL POLICIES

   Cash Fund's fundamental investment policies are:

 1.  Not to purchase any securities other than those referred to under "Security
     Cash Fund," page 13;

 2.  Not to borrow money, except that the Fund may borrow for temporary purposes
     or to meet redemption  requests which might otherwise  require the untimely
     disposition of a security (not for leveraging) in amounts not exceeding 10%
     of the current value of its total assets  (including  the amount  borrowed)
     less  liabilities  (not  including  the  amount  borrowed)  at the time the
     borrowing  is  made.  It is  intended  that  any  such  borrowing  will  be
     liquidated before additional portfolio securities are purchased;

     in real estate;

14.  Not to invest  for the  purpose of  exercising  control  of  management  of

   In order to permit  the sale of shares of Cash Fund in  certain  states,  the
Fund may make commitments  more  restrictive  than the fundamental  restrictions
described above. Should the Fund determine that any such commitment is no longer
in the best  interest  of the  Fund and its  stockholders,  it will  revoke  the
commitment by terminating sales of its shares in the state(s) involved.

   Any investment  restriction except restriction 2, which involves a maximum or
minimum  percentage  of  securities  or  assets  shall not be  considered  to be
violated  unless an excess  over or a  deficiency  under the  percentage  occurs

or utilization of assets by Cash Fund.

CORPORATE BOND, LIMITED MATURITY BOND, U.S. GOVERNMENT, HIGH YIELD AND MUNICIPAL
BOND FUNDS

   Security  Distributors,  Inc. (the "Distributor"),  700 SW Harrison,  Topeka,
Kansas, a wholly-owned  subsidiary of Security Benefit Group, Inc., is principal
underwriter for Corporate Bond,  Limited  Maturity Bond, U.S.  Government,  High
Yield and Municipal  Bond Funds.  Investors  may purchase  shares of these Funds
through  authorized  dealers  who are  members of the  National  Association  of
Securities Dealers, Inc. In addition, banks and other financial institutions may
make  shares  of the  Funds  available  to their  customers.  (Banks  and  other
financial  institutions  that  make  shares  of the  Funds  available  to  their
customers in Texas must be registered  with that state as  securities  dealers.)
The minimum initial purchase must be $100 and subsequent  purchases must be $100
unless made through an Accumulation Plan which allows a minimum initial purchase
of $100 and subsequent  purchases of $20. (See "Accumulation Plan," page 38.) An
application may be obtained from the Distributor.
    
   Orders  for the  purchase  of  shares of the Funds  will be  confirmed  at an
offering  price  equal to the net asset  value per share next  determined  after
receipt  of the order in proper  form by the  Distributor  (generally  as of the
close of the  Exchange on that day) plus the sales charge in the case of Class A
shares of the Funds.  Orders  received  by dealers or other  firms  prior to the
close of the Exchange and received by the Distributor  prior to the close of its
business day will be confirmed at the offering  price  effective as of the close
of the  Exchange on that day.  Dealers and other  financial  services  firms are
obligated to transmit orders promptly.

ALTERNATIVE PURCHASE OPTIONS
   
   Corporate  Bond,  Limited  Maturity  Bond,  U.S.  Government,  High Yield and
Municipal Bond Funds offer two classes of shares:
    
   CLASS A SHARES - FRONT-END LOAD OPTION.  Class A shares are sold with a sales
charge at the time of purchase. Class A shares are not subject to a sales charge
when they are redeemed  (except that shares sold in an amount of  $1,000,000  or
more without a front-end  sales charge will be subject to a contingent  deferred
sales charge of 1% for one year).  See Appendix A for a discussion of "Rights of
Accumulation"  and "Statement of  Intention,"  which options may serve to reduce
the front-end sales charge.

   CLASS B SHARES - BACK-END  LOAD  OPTION.  Class B shares  are sold  without a
sales charge at the time of purchase, but are subject to a deferred sales charge
if they are redeemed  within five years of the date of purchase.  Class B shares
will automatically  convert tax-free to Class A shares at the end of eight years
after purchase.

   The decision as to which class is more  beneficial to an investor  depends on
the amount and intended length of the investment. Investors who would rather pay
the entire cost of distribution at the time of investment, rather than spreading
such cost over  time,  might  consider  Class A shares.  Other  investors  might
consider  Class B shares,  in which case 100% of the purchase  price is invested
immediately,  depending on the amount of the purchase and the intended length of
investment. The Funds will not normally accept any purchase of Class B shares in
the amount of $250,000 or more.

   Dealers or others may receive  different levels of compensation  depending on
which class of shares they sell.

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

   Purchases of Class A shares of these Funds in amounts of  $1,000,000  or more
are at net asset value (without a sales charge), but are subject to a contingent
deferred sales charge of 1% in the event of redemption within one year following
purchase.  For a  discussion  of  the  contingent  deferred  sales  charge,  see
"Calculation  and Waiver of  Contingent  Deferred  Sales  Charges"  page 37. The
Distributor  will pay a commission to dealers on purchases of $1,000,000 or more
as follows: 1.00% on sales up to $5,000,000, plus .50% on sales of $5,000,000 or
more up to $10,000,000, and .10% on any amount of $10,000,000 or more.
   
   The Investment Manager may, at its expense,  pay a service fee to dealers who
satisfy certain criteria established by the Investment Manager from time to time
relating to the volume of their sales of Class A shares of  Municipal  Bond Fund
and certain other Security Funds during prior periods and certain other factors,
including  providing to their clients who are  stockholders of the Funds certain
services,  which include assisting in maintaining  records,  processing purchase
and  redemption  requests  and  establishing  shareholder  accounts,   assisting
shareholders in changing  account  options or enrolling in specific  plans,  and
providing   shareholders  with  information  regarding  the  Funds  and  related
developments.  Service fees are paid  quarterly and may be  discontinued  at any
time.

SECURITY INCOME  AND MUNICIPAL BOND FUNDS' CLASS A DISTRIBUTION PLANS

   As discussed in the  prospectus,  each of Corporate  Bond,  Limited  Maturity
Bond,  U.S.  Government,  High Yield and Municipal Bond Funds has a Distribution
Plan for its Class A shares pursuant to Rule 12b-1 under the Investment  Company
Act of 1940.  Each  Plan  authorizes  these  Funds to pay an  annual  fee to the
Distributor  of .25% of the average  daily net asset value of the Class A shares
of each Fund to finance various activities  relating to the distribution of such
shares of the Funds to investors.  These expenses  include,  but are not limited
to, the payment of compensation  (including  compensation to securities  dealers
and  other  financial   institutions  and   organizations)   to  obtain  various
administrative  services  for each Fund.  These  services  include,  among other
things,  processing  new  shareholder  account  applications  and serving as the
primary  source of information  to customers in answering  questions  concerning
each  Fund  and  their  transactions  with the  Fund.  The  Distributor  is also
authorized to engage in advertising,  the preparation and  distribution of sales
literature  and  other  promotional  activities  on  behalf  of each  Fund.  The
Distributor is required to report in writing to the Board of Directors of Income
Fund and the board will review at least quarterly the amounts and purpose of any
payments made under the Plan.  The  Distributor  is also required to furnish the
board with such other  information  as may  reasonably  be requested in order to
enable the board to make an informed determination of whether the Plan should be
continued.

   For Income  Fund,  the Plan  became  effective  on August 15,  1985,  and was
renewed by the  directors  of Income  Fund on  February  6, 1998,  as to each of
Corporate Bond and U.S.  Government  Funds. The Plan was adopted with respect to
Limited  Maturity  Bond on October 21, 1994 and was renewed by the  directors of
Income Fund on February 6, 1998.  The Plan was adopted  with respect to the High
Yield  Fund on May 3,  1996,  and  renewed by the  directors  of Income  Fund on
February 6, 1998. For Municipal  Bond Fund, the Plan became  effective on May 1,
1998. Each Plan will continue from year to year,  provided that such continuance
is approved at least  annually by a vote of a majority of the Board of Directors
of each Fund,  including a majority of the independent  directors cast in person
at a meeting called for the purpose of voting on such continuance.  The Plan can
also be terminated at any time on 60 days' written notice, without penalty, if a
majority of the disinterested directors or the

                                       33
<PAGE>
Class A shareholders  vote to terminate the Plan. Any agreement  relating to the
implementation of the Plan terminates automatically if it is assigned. The Plans
may not be amended to  increase  materially  the amount of  payments  thereunder
without approval of the Class A shareholders of the Funds.

   Because all amounts paid  pursuant to the  Distribution  Plan are paid to the
Distributor,  the Investment Manager and its officers,  directors and employees,
including Messrs.  Cleland and Schmank (directors of the Fund),  Messrs.  Young,
Schmank and  Swickard,  Ms.  Tedder,  Ms. Lee and Ms.  Harwood  (officers of the
Fund), all may be deemed to have a direct or indirect  financial interest in the
operation of the  Distribution  Plan. None of the  independent  directors have a
direct or indirect financial interest in the operation of the Distribution Plan.

   Benefits  from the  Distribution  Plan may  accrue  to the  Funds  and  their
stockholders  from the  growth  in assets  due to sales of shares to the  public
pursuant to the Distribution  Agreement with the  Distributor.  Increases in the
Corporate Bond, Limited Maturity Bond, U.S. Government, High Yield and Municipal
Bond  Funds'  net  assets  from  sales  pursuant  to its  Distribution  Plan and
Agreement may benefit  shareholders by reducing per share  expenses,  permitting
increased investment  flexibility and diversification of Corporate Bond, Limited
Maturity Bond, U.S.  Government and High Yield Funds' assets,  and  facilitating
economies  of  scale  (e.g.,   block   purchases)   in  the  Funds'   securities
transactions.

   Distribution  fees paid by Class A stockholders  of Corporate  Bond,  Limited
Maturity Bond, U.S. Government and High Yield Funds to the Distributor under the
Plan for the year ended  December  31,  1997,  totaled  $________.  In addition,
$_______  was  carried  forward  from  the  previous  plan  year.  Approximately
$________  of this  amount  was  paid as a  service  fee to  broker/dealers  and
$_______ was spent on  promotions,  resulting in a deficit of $______ going into
the 1998 plan year. The amount spent on promotions consists primarily of amounts
reimbursed  to  dealers  for  expenses  (primarily  travel,  meals and  lodging)
incurred in connection with attendance by their  representatives  at educational
meetings  concerning  Corporate Bond and U.S.  Government Funds. The Distributor
may engage the services of an  affiliated  advertising  agency for  advertising,
preparation of sales literature and other distribution-related activities.
    
CLASS B SHARES
   
   Class B shares of Corporate Bond,  Limited  Maturity Bond,  U.S.  Government,
High Yield and Municipal  Bond Funds are offered at net asset value,  without an
initial sales charge. With certain exceptions, these Funds may impose a deferred
sales charge on shares  redeemed  within five years of the date of purchase.  No
deferred sales charge is imposed on amounts redeemed thereafter. If imposed, the
deferred sales charge is deducted from the redemption proceeds otherwise payable
to the stockholder. The deferred sales charge is retained by the Distributor.
    
   Whether a contingent  deferred  sales charge is imposed and the amount of the
charge will depend on the number of years since the stockholder  made a purchase
payment  from  which an amount is being  redeemed,  according  to the  following
schedule:

  YEAR SINCE PURCHASE PAYMENT WAS MADE         CONTINGENT DEFERRED SALES CHARGE
  ------------------------------------         --------------------------------
               First                                           5%
               Second                                          4%
               Third                                           3%
               Fourth                                          3%
               Fifth                                           2%
          Sixth and Following                                  0%
   
   Class B shares (except shares purchased through the reinvestment of dividends
and other  distributions  with  respect  to Class B shares)  will  automatically
convert on the eighth  anniversary  of the date such  shares were  purchased  to
Class A shares which are subject to a lower,  or in the case of  Municipal  Bond
Fund, no distribution fee. This automatic conversion of Class B shares will take
place  without   imposition  of  a  front-end  sales  charge  or  exchange  fee.
(Conversion of Class B shares represented by stock certificates will require the
return  of  the  stock  certificates  to the  Investment  Manager.)  All  shares
purchased through reinvestment of dividends and other distributions with respect
to Class B shares  ("reinvestment  shares")  will be  considered to be held in a
separate subaccount.  Each time any Class B shares (other than those held in the
subaccount)  convert to Class A shares,  a pro rata portion of the  reinvestment
shares held in the subaccount will also convert to Class A shares.

                                       34
<PAGE>
Class B shares so  converted  will no longer be subject  to the higher  expenses
borne by Class B shares.  Because  the net asset  value per share of the Class A
shares  may be  higher  or lower  than that of the Class B shares at the time of
conversion,  although  the dollar  value  will be the same,  a  shareholder  may
receive more or less Class A shares than the number of Class B shares converted.
Under  current law, it is the Funds'  opinion  that such a  conversion  will not
constitute a taxable event under federal  income tax law. In the event that this
ceases to be the case, the Board of Directors will consider what action, if any,
is appropriate and in the best interests of the Class B stockholders.
    
CLASS B DISTRIBUTION PLAN
   
   Each of Corporate Bond,  Limited Maturity Bond, U.S.  Government,  High Yield
and  Municipal  Bond Funds bear some of the costs of selling  its Class B shares
under a  Distribution  Plan adopted with respect to its Class B shares ("Class B
Distribution  Plan") pursuant to Rule 12b-1 under the Investment  Company Act of
1940 ("1940 Act").  This Plan was adopted by the Board of Directors of Corporate
Bond, U.S.  Government and Municipal Bond Funds on July 23, 1993 and was renewed
on February 6, 1998. The Plan was adopted with respect to Limited  Maturity Bond
Fund on October  21,  1994 and was  renewed on  February  6, 1998.  The Plan was
adopted with  respect to the High Yield Fund on May 3, 1996,  and renewed by the
directors of Income Fund on February 6, 1998.  The Plan provides for payments at
an annual rate of 1.00% of the average  daily net asset value of Class B shares.
Amounts paid by the Funds are currently used to pay dealers and other firms that
make Class B shares available to their customers (1) a commission at the time of
purchase  normally  equal  to 4.00% of the  value of each  share  sold and (2) a
service fee payable for the first year, initially, and for each year thereafter,
quarterly,  in an amount equal to .25%  annually of the average  daily net asset
value of Class B shares  sold by such  dealers  and other  firms  and  remaining
outstanding on the books of the Funds.

   Rules of the National Association of Securities Dealers,  Inc. ("NASD") limit
the aggregate  amount that each Fund may pay annually in distribution  costs for
the sale of its Class B shares to 6.25% of gross  sales of Class B shares  since
the inception of the Distribution  Plan, plus interest at the prime rate plus 1%
on such amount  (less any  contingent  deferred  sales  charges  paid by Class B
shareholders to the Distributor). The Distributor intends, but is not obligated,
to continue to pay or accrue  distribution  charges  incurred in connection with
the Class B Distribution Plan which exceed current annual payments  permitted to
be received by the Distributor from the Funds.  The Distributor  intends to seek
full  payment of such  charges  from the Fund  (together  with  annual  interest
thereon  at the prime  rate plus 1%) at such time in the  future  as, and to the
extent that, payment thereof by the Funds would be within permitted limits.

   Each Fund's Class B  Distribution  Plan may be terminated at any time by vote
of its  directors who are not  interested  persons of the Fund as defined in the
1940 Act or by vote of a  majority  of the  outstanding  Class B shares.  In the
event the Class B Distribution Plan is terminated by the Class B stockholders or
the Funds' Board of Directors,  the payments made to the Distributor pursuant to
the Plan up to that time would be  retained  by the  Distributor.  Any  expenses
incurred by the Distributor in excess of those payments would be absorbed by the
Distributor.  Distribution  fees paid by Class B stockholders of Corporate Bond,
Limited Maturity Bond, U.S.  Government,  High Yield and Municipal Bond Funds to
the  Distributor  under the Plan for the year ended  December 31, 1997,  totaled
$_______. The Funds make no payments in connection with the sales of their Class
B shares other than the distribution fee paid to the Distributor.
    
CALCULATION AND WAIVER OF CONTINGENT DEFERRED SALES CHARGES

   Any  contingent  deferred  sales charge  imposed upon  redemption  of Class A
shares  (purchased  in an amount of  $1,000,000 or more) and Class B shares is a
percentage  of the lesser of (1) the net asset  value of the shares  redeemed or
(2) the net cost of such shares. No contingent  deferred sales charge is imposed
upon redemption of amounts derived from (1) increases in the value above the net
cost of such  shares due to  increases  in the net asset  value per share of the
Fund; (2) shares acquired  through  reinvestment of income dividends and capital
gain distributions;  or (3) Class A shares (purchased in an amount of $1,000,000
or more)  held for more than one year or Class B shares  held for more than five
years.  Upon  request  for  redemption,  shares not  subject  to the  contingent
deferred  sales  charge  will be  redeemed  first.  Thereafter,  shares held the
longest will be the first to be redeemed.

   The contingent  deferred sales charge is waived: (1) following the death of a
stockholder  if  redemption  is made within one year after  death,  (2) upon the
disability (as defined in Section 72(m)(7) of the Internal Revenue Code) of

                                       35
<PAGE>
a  stockholder  prior to age 65 if  redemption is made within one year after the
disability,  provided such disability  occurred after the stockholder opened the
account; (3) in connection with required minimum distributions in the case of an
IRA,  SAR-SEP or Keogh or any other  retirement  plan  qualified  under  Section
401(a),  401(k) or 403(b) of the Code; and (4) in the case of distributions from
retirement  plans  qualified  under  Section  401(a) or  401(k) of the  Internal
Revenue  Code due to (i)  returns  of excess  contributions  to the  plan,  (ii)
retirement of a participant in the plan,  (iii) a loan from the plan  (repayment
of loans,  however,  will  constitute  new sales for purposes of  assessing  the
CDSC),  (iv) "financial  hardship" of a participant in the plan, as that term is
defined in Treasury Regulation Section 1.401(k)-1(d)(2), as amended from time to
time, (v) termination of employment of a participant in the plan, (vi) any other
permissible  withdrawal  under the terms of the plan.  The  contingent  deferred
sales  charge  will also be waived in the case of  redemptions  of shares of the
Funds  pursuant  to a  Systematic  Withdrawal  Program  (refer  to  page  38 for
details).

ARRANGEMENTS WITH BROKER/DEALERS AND OTHERS

   The  Investment  Manager  or  Distributor,  from time to time,  will  provide
promotional  incentives or pay a bonus to certain dealers whose  representatives
have sold or are  expected  to sell  significant  amounts  of the  Funds  and/or
certain  other  Funds  managed  by  the  Investment  Manager.  Such  promotional
incentives  will include  payment for attendance  (including  travel and lodging
expenses)  by  qualifying  registered  representatives  (and  members  of  their
families)  to sales  seminars  at luxury  resorts  within or without  the United
States.  Bonus  compensation may include  reallowance of the entire sales charge
and may also  include,  with respect to Class A shares,  an amount which exceeds
the entire  sales charge and,  with  respect to Class B shares,  an amount which
exceeds the maximum commission. The Distributor,  or the Investment Manager, may
also  provide  financial  assistance  to  certain  dealers  in  connection  with
conferences,  sales or training  programs for their employees,  seminars for the
public,  advertising,  sales campaigns, and/or shareholder services and programs
regarding one or more of the funds managed by the Investment Manager. Certain of
the  promotional  incentives  or bonuses  may be  financed  by  payments  to the
Distributor  under a Rule 12b-1  Distribution  Plan.  The payment of promotional
incentives  and/or  bonuses  will not change the price an investor  will pay for
shares or the amount that the Funds will receive from such sale. No compensation
will be  offered  to the  extent  it is  prohibited  by the laws of any state or
self-regulatory  agency, such as the National Association of Securities Dealers,
Inc. ("NASD"). A Dealer to whom substantially the entire sales charge of Class A
shares  is  reallowed  may  be  deemed  to be  an  "underwriter"  under  federal
securities laws.

   The Distributor  also may pay banks and other  financial  services firms that
facilitate  transactions  in shares of the funds for their clients a transaction
fee up to the level of the  payments  made  allowable to dealers for the sale of
such  shares as  described  above.  Banks  currently  are  prohibited  under the
Glass-Steagall Act from providing certain underwriting or distribution services.
If banking firms were prohibited from acting in any capacity or providing any of
the  described  services,  the Fund's Board of  Directors  would  consider  what
action, if any, would be appropriate.

   In  addition,  state  securities  laws on this  issue  may  differ  from  the
interpretations  of  federal  law  expressed  herein  and  banks  and  financial
institutions may be required to register as dealers pursuant to state law.

   The Investment  Manager or Distributor also may pay a marketing  allowance to
dealers who meet  certain  eligibility  criteria.  This  allowance  is paid with
reference to new sales of Fund shares (except shares of Cash Fund) in a calendar
year and may be  discontinued  at any time. To be eligible for this allowance in
any given  year,  the dealer  must sell a minimum of  $2,000,000  of Class A and
Class B shares during that year. The applicable  marketing allowance factors are
set forth below.

CASH FUND

   Cash fund offers a single class of shares which is offered at net asset value
next  determined  after an order is accepted.  There is no sales charge or load.
The minimum initial investment in Cash Fund is $100 for each account. Subsequent
investments may be made in any amount of $20 or more. Cash Fund purchases may be
made in any of the following ways:

1.  BY MAIL.

    (a)  A check or negotiable bank draft should be sent to:

                               Security Cash Fund
                                  P.O. Box 2548
                            Topeka, Kansas 66601-2548

    (b)  Make check or draft payable to "Security Cash Fund."

    (c)  For initial investment include a completed investment application found
         at the back of the prospectus.

2.  BY WIRE.

    (a)  Call the Fund to advise  of the  investment.  The Fund  will  supply an
         account  number  at the  time of the  initial  investment  and  provide
         instructions for having your bank wire federal funds.

    (b)  For an initial  investment,  you must also send a completed  investment
         application to the Fund.

3.  THROUGH BROKER/DEALERS.  Investors may, if they wish, invest in Cash Fund by
    purchasing shares through registered broker/dealers. Such broker/dealers who
    process  orders  on  behalf of their  customers  may  charge a fee for their
    services.   Investments   made   directly   without  the   assistance  of  a
    broker/dealer are without charge.

   Since Cash Fund invests in money market  securities  which require  immediate
payment in federal funds,  monies  received from the sales of its shares must be
monies held by a commercial bank and be on deposit at one of the Federal Reserve
Banks.  A record date for each  stockholder's  investment  is  established  each
business day and used to distribute  the following  day's  dividend.  If federal
funds are received prior to 2:00 p.m. (Central time) the investment will be made
on that day and the investor will receive the following day's dividend.  Federal
funds  received  after 2:00 p.m. on any business day will not be invested  until
the following  business day. Cash Fund will not be responsible for any delays in
the wire transfer system.  All checks are accepted subject to collection at full
face value in United States funds and must be drawn in United States  dollars on
a United States bank.

PURCHASES AT NET ASSET VALUE
   
   Class A shares of Corporate Bond,  Limited  Maturity Bond,  U.S.  Government,
High Yield and  Municipal  Bond Funds may be purchased at net asset value by (1)
directors, officers and employees of the Funds, the Funds' Investment Manager or
Distributor;   directors,  officers  and  employees  of  Security  Benefit  Life
Insurance  Company and its  subsidiaries;  agents licensed with Security Benefit
Life Insurance Company; spouses or minor children of any such agents; as well as
the following relatives of any such directors, officers and employees (and their
spouses): spouses,  grandparents,  parents, children,  grandchildren,  siblings,
nieces and nephews; (2) any trust, pension, profit sharing or other benefit plan
established by any of the foregoing  corporations  for persons  described above;
(3) retirement plans where third party administrators of such plans have entered
into certain  arrangements with the Distributor or its affiliates  provided that
no commission is paid to dealers; and (4) officers,

                                       37
<PAGE>
directors,  partners or registered  representatives (and their spouses and minor
children) of  broker/dealers  who have a selling agreement with the Distributor.
Such  sales  are made  upon the  written  assurance  of the  purchaser  that the
purchase is made for  investment  purposes and that the  securities  will not be
transferred or resold except through redemption or repurchase by or on behalf of
the Funds.
    
   Life agents and associated  personnel of broker/dealers must obtain a special
application from their employer or from the Distributor, in order to qualify for
such purchases.
   
   Class A shares of Corporate Bond,  Limited  Maturity Bond,  U.S.  Government,
High Yield and  Municipal  Bond Funds may also be  purchased  at net asset value
when the purchase is made on the  recommendation of (i) a registered  investment
adviser,  trustee or financial intermediary who has authority to make investment
decisions on behalf of the investor;  or (ii) a certified  financial  planner or
registered  broker-dealer  who either charges periodic fees to its customers for
financial  planning,  investment  advisory  or  asset  management  services,  or
provides  such services in connection  with the  establishment  of an investment
account for which a comprehensive "wrap fee" is imposed. The Distributor must be
notified when a purchase is made that qualifies under this provision.
    
ACCUMULATION PLAN
   
   Investors in Corporate Bond,  Limited  Maturity Bond, U.S.  Government,  High
Yield or Municipal  Bond Fund may purchase  shares on a periodic  basis under an
Accumulation Plan which provides for an initial investment of $100 minimum,  and
subsequent  investments  of $20 minimum at any time. An  Accumulation  Plan is a
voluntary program, involving no obligation to make periodic investments,  and is
terminable at will.  Payments are made by sending a check to the Distributor who
(acting as an agent for the dealer) will purchase whole and fractional shares of
the Funds as of the close of business  on the day such  payment is  received.  A
confirmation  and  statement of account  will be sent to the investor  following
each investment.  Certificates for whole shares will be issued upon request.  No
certificates will be issued for fractional shares which may be withdrawn only by
redemption for cash.
    
   Investors may choose to use  "Secur-O-Matic"  (automatic  bank draft) to make
their Fund purchases. There is no additional charge for using Secur-O-Matic.  An
application may be obtained from the Funds.

SYSTEMATIC WITHDRAWAL PROGRAM

   A Systematic  Withdrawal  Program may be established by stockholders who wish
to receive regular monthly,  quarterly,  semiannual or annual payments of $25 or
more.  A Program may also be based upon the  liquidation  of a fixed or variable
number of shares  provided that the minimum  amount is withdrawn.  However,  the
Funds do not recommend this (or any other amount) as an appropriate  withdrawal.
Shares with a current  offering  price of $5,000 or more must be deposited  with
the Investment  Manager acting as agent for the  stockholder  under the Program.
There is no service  charge on the Program as the  Investment  Manager  pays the
costs involved.
   
   Sufficient shares will be liquidated at net asset value to meet the specified
withdrawals.   Liquidation  of  shares  may  deplete  or  possibly  use  up  the
investment,  particularly in the event of a market  decline.  Payments cannot be
considered  as actual yield or income since part of such payments is a return of
capital and may constitute a taxable event to the  stockholder.  The maintenance
of a Withdrawal  Program  concurrently  with  purchases of additional  shares of
Corporate Bond, Limited Maturity Bond, U.S. Government,  High Yield or Municipal
Bond Fund would be  disadvantageous  because of the sales commission  payable in
respect to such  purchases.  During the withdrawal  period,  no payments will be
accepted  under  an  Accumulation  Plan.  Income  dividends  and  capital  gains
distributions  are  automatically  reinvested at net asset value. If an investor
has an Accumulation  Plan in effect,  it must be terminated  before a Systematic
Withdrawal Program may be initiated.
    
   The stockholder receives  confirmation of each transaction showing the source
of the payment and the share balance remaining in the Program.  A Program may be
terminated  on  written  notice by the  stockholder  or the  Funds,  and it will
terminate  automatically  if all shares are  liquidated  or  withdrawn  from the
account.

   A stockholder may establish a Systematic  Withdrawal  Program with respect to
Class B shares  without the  imposition of any  applicable  contingent  deferred
sales charge,  provided  that such  withdrawals  do not in any 12-month  period,
beginning on the date the Program is established, exceed 10% of the value of the
account  on  that  date  ("Free   Systematic   Withdrawals").   Free  Systematic
Withdrawals are not available if a Program  established  with respect to Class B
shares  provides for withdrawals in excess of 10% of the value of the account in
any Program  year and,  as a result,  all  withdrawals  under such a Program are
subject to any  applicable  contingent  deferred sales charge.  Free  Systematic
Withdrawals will be made first by redeeming those shares that

                                       38
<PAGE>
are not subject to the  contingent  deferred  sales charge and then by redeeming
shares held the longest.  The contingent  deferred sales charge  applicable to a
redemption of Class B shares  requested  while Free  Systematic  Withdrawals are
being made will be  calculated  as described  under  "Calculation  and Waiver of
Contingent Deferred Sales Charges," page 35. A Systematic Withdrawal form may be
obtained from the Funds.

Board of Directors at a regular  meeting held February 6, 1998.  The  Investment
Manager also acts as investment adviser to Security Equity Fund, Security Growth

extraordinary  expenses and Class B  distribution  fees) shall not for Corporate
Bond,  Limited  Maturity Bond,  U.S.  Government and High Yield Funds exceed the

expense  limitation  imposed  by any state in which  shares of the Fund are then
qualified  for sale and shall not for Cash Fund exceed 1% of the Fund's  average
net assets for the year. (The Investment  Manager is not aware of any state that

Bond Fund, the Investment  Manager guarantees that the aggregate annual expenses
of the Fund  (including for any fiscal year,  the management  fee, but excluding
interest,  taxes  extraordinary  expenses,  and Class A and Class B distribution
fees)  shall not exceed 1% of the Fund's  average  net assets for the year.  The
Investment  Manager  will  contribute  such funds or waive  such  portion of its
management fee as may be necessary to insure that the aggregate  expenses of the
Funds will not exceed the guaranteed maximum.

   The Investment  Manager has engaged  Salomon  Brothers Asset  Management Inc.

such services,  the Investment Manager pays Salomon Brothers and amount equal to
 .22% of the average net assets of Municipal Bond Fund, computed on a daily basis
and payable  monthly.  The  Sub-Advisory  Agreement  may be  terminated  without
penalty  at  any  time  by  either  party  on 60  days'  written  notice  and is
automatically terminated in the event of its assignment or in the event that the
Investment  Advisory  Contract  between the  Investment  Manager and the Fund is

CODE OF ETHICS

   The Funds, the Investment  Manager and the Distributor have a written Code of
Ethics  which  requires  all access  persons to obtain  prior  clearance  before
engaging  in  any  personal  securities  transactions.  Access  persons  include
officers and directors of the Funds and  Investment  Manager and employees  that
participate  in,  or  obtain  information  regarding,  the  purchase  or sale of
securities   by  the  Funds  or  whose  job   relates   to  the  making  of  any
recommendations with respect to such purchases or sales. All access persons must
report their personal securities transactions within ten days of the end of each
calendar quarter. Access persons will not be permitted to effect transactions in
a security if it: (a) is being considered for purchase or sale by one or more of
the Funds; (b) is being purchased or sold by one or more of the Funds; or (c) is
being offered in an initial public offering. In addition, portfolio managers are
prohibited  from  purchasing  or selling a security  within seven  calendar days
before  or after a Fund that he or she  manages  trades  in that  security.  Any
material  violation of the Code of Ethics is reported to the Board of the Funds.
The Board also  reviews  the  administration  of the Code of Ethics on an annual
basis.

DISTRIBUTOR
   
   Security  Distributors,  Inc. (the  "Distributor"),  a Kansas corporation and
wholly-owned subsidiary of Security Benefit Group, Inc., serves as the principal
underwriter  for  shares  of  Corporate  Bond,   Limited   Maturity  Bond,  U.S.
Government,  High  Yield and  Municipal  Bond  Funds  pursuant  to  Distribution
Agreements dated March 27, 1984, as amended, and October 7, 1983,  respectively.
The Distributor also acts as principal  underwriter for the following investment
companies: Security Equity Fund, Security Growth and Income Fund, Security Ultra
Fund,  Variflex Variable Annuity Account  (Variflex),  Variflex Variable Annuity
Account (Variflex Educator Series),  SBL Variable Annuity Account VIII (Variflex
LS), SBL Variable  Annuity  Account VIII  (Variflex  Signature),  the  Parkstone
Variable Annuity Account and Security Varilife Separate Account.
    
   The Distributor  receives a maximum commission on Class A Shares of 4.75% and
allows a maximum discount of 4.0% from the offering price to authorized  dealers
on Fund shares sold. The discount is alike for all dealers,  but the Distributor
may increase it for specific periods at its discretion. Salespersons employed by
dealers may also be licensed to sell insurance with Security Benefit Life.
   
   For  the  fiscal  year  ended  December  31,  1997,  the  gross  underwriting
commissions (Class A and B shares) received and the net underwriting  commission
retained by the Distributor were as follows:

gross underwriting

                                       42

commissions  on sales of Class A shares of $80,868 and  $244,043 for Income Fund

commissions  of $9,910 and  $48,307  for Income  Fund and $4,103 and $13,009 for
Municipal  Bond Fund for the fiscal  years  ended  December  31,  1995 and 1994,
respectively.
    
   The Distributor,  on behalf of the Funds, may act as a broker in the purchase
and sale of securities not effected on a securities exchange,  provided that any
such  transactions  and any  commissions  shall comply with  requirements of the
Investment  Company Act of 1940 and all rules and  regulations of the Securities
and Exchange Commission. The Distributor has not acted as a broker.

   Each Fund's Distribution Agreement is renewable annually either by the Funds'
Board  of  Directors  or by a  vote  of a  majority  of the  Fund's  outstanding
securities, and, in either event, by a majority of the board who are not parties
to the agreement or interested  persons of any such party. The agreements may be
terminated by either party upon 60 days' written notice.

ALLOCATION OF PORTFOLIO BROKERAGE

   Transactions  in  portfolio  securities  shall be  effected in such manner as
deemed  to be in the best  interest  of each  respective  Fund.  In  reaching  a
judgment relative to the qualifications of a broker or dealer to obtain the best
execution of a particular  transaction,  all relevant factors and  circumstances
will be taken into account by the Investment Manager, including consideration of
the overall  reasonableness of commissions paid to a broker,  the firm's general
execution  and  operational  capabilities,  and its  reliability  and  financial
condition. The Funds do not anticipate that they will incur a significant amount
of brokerage commissions because fixed income securities are generally traded on
a "net" basis--that is, in principal amount without the addition or deduction of
a stated brokerage commission,  although the net price usually includes a profit
to the  dealer.  The Funds will deal  directly  with the  selling or  purchasing
principal  without  incurring charges for the services of a broker on its behalf
unless it is  determined  that a better  price or  execution  may be obtained by
utilizing  the  services  of a broker.  The Funds  also may  purchase  portfolio
securities  in  underwritings  where the price  includes  a fixed  underwriter's
concession or discount.  Money market instruments may be purchased directly from
the issuer at no commission or discount.

   Portfolio  transactions  that require a broker may be directed to brokers who
furnish investment  information or research services to the Investment  Manager.
Such investment information and research services include advice as to the value
of  securities,   the  advisability  of  investing  in,  purchasing  or  selling
securities  and the  availability  of  securities  and  purchasers or sellers of
securities,  and furnishing analyses and reports concerning issues,  industries,
securities,  economic factors and trends, portfolio strategy, and performance of
accounts.  Such investment information and research services may be furnished by
brokers in many ways,  including:  (1) on-line data base systems,  the equipment
for which is provided by the broker,  that enable  registrant to have  real-time
access  to market  information,  including  quotations;  (2)  economic  research
services,  such as  publications,  chart  services  and advice  from  economists
concerning macroeconomic information;  and (3) analytical investment information
concerning  particular  corporations.  If a transaction  is directed to a broker
supplying such information or services, the commission paid for such transaction
may be in excess  of the  commission  another  broker  would  have  charged  for
effecting  that  transaction,  provided that the  Investment  Manager shall have
determined  in good faith that the  commission  is reasonable in relation to the
value of the investment information or the research services provided, viewed in
terms of either that particular  transaction or the overall  responsibilities of
the  Investment  Manager  with  respect to all accounts as to which it exercises
investment discretion. The Investment Manager may use all, none, or some of such
information and services in providing  investment  advisory  services to each of
the mutual funds under its management, including the Funds.

   In addition,  brokerage  transactions may be placed with  broker/dealers  who
sell shares of the Funds  managed by the  Investment  Manager who may or may not
also provide  investment  information  and  research  services.  The  Investment
Manager may, consistent with the NASD Rules of Fair Practice,  consider sales of
Fund shares in the selection of a broker/dealer.
   
   Securities  held by the Funds may also be held by other  investment  advisory
clients of the Investment  Manager,  including other  investment  companies.  In
addition,  the  Investment  Manager's  parent  company,  Security  Benefit  Life
Insurance  Company  ("SBL"),  may also hold some of the same  securities  as the
Funds. When selecting securities for purchase or sale for a Fund, the Investment
Manager may at the same time be  purchasing or selling the same  securities  for
one or  more  of  such  other  accounts.  Subject  to the  Investment  Manager's
obligation  to seek best  execution,  such  purchases  or sales may be  executed
simultaneously or "bunched." It is

                                       43
<PAGE>
the policy of the  Investment  Manager not to favor one account  over the other.
Any  purchase or sale orders  executed  simultaneously  (which may also  include
orders from SBL) are allocated at the average price and as nearly as practicable
on a pro rata basis  (transaction  costs will also  generally be shared on a pro
rata basis) in proportion to the amounts desired to be purchased or sold by each
account.  In those instances  where it is not practical to allocate  purchase or
sale orders on a pro rata basis,  then the allocation will be made on a rotating
or other equitable basis. While it is conceivable that in certain instances this
procedure could  adversely  affect the price or number of shares involved in the
Fund's transaction,  it is believed that the procedure generally  contributes to
better  overall  execution of the Funds'  portfolio  transactions.  The Board of
Directors of the Funds has adopted guidelines  governing this procedure and will
monitor the procedure to determine  that the  guidelines  are being followed and
that the  procedure  continues  to be in the best  interest  of the Fund and its
stockholders.  With  respect  to the  allocation  of  initial  public  offerings
("IPOs"),  the  Investment  Manager may determine not to purchase such offerings
for certain of its clients  (including  investment  company  clients) due to the
limited number of shares  typically  available to the  Investment  Manager in an
IPO.  No  brokerage  commissions  were paid by the  Funds  for the  years  ended
December 31, 1997, 1996, and 1995.
    
DETERMINATION OF NET ASSET VALUE
   
   The net asset value per share of each Fund is  determined  as of the close of
regular trading hours on the New York Stock Exchange (normally 3:00 p.m. Central
time) on each day that the Exchange is open for trading, which is Monday through
Friday except for the following  dates when the Exchange is closed in observance
of Federal  holidays:  New Year's Day, Martin Luther King, Jr. Day,  Presidents'
Day, Good Friday,  Memorial Day, July Fourth,  Labor Day,  Thanksgiving  Day and
Christmas  Day.  The  determination  is made by dividing  the total value of the
portfolio  securities  of each Fund,  plus any cash or other  assets  (including
dividends  accrued but not collected),  less all  liabilities,  by the number of
shares outstanding of the Fund.
    
   Securities listed or traded on a national  securities  exchange are valued at
the last  sale  price.  If there  are no sales  on a  particular  day,  then the
securities  are  valued at the last bid  price.  All other  securities,  held by
Corporate Bond, Limited Maturity Bond, U.S. Government and High Yield Funds, for
which market  quotations are readily  available,  are valued on the basis of the
last current bid price.  If there is no bid price, or if the bid price is deemed
to be  unsatisfactory  by the Board of Directors,  then the securities  shall be
valued in good faith by such method as the Board of  Directors  determines  will
reflect fair market value. Valuations of the Funds' securities are supplied by a
pricing service approved by the Board of Directors.

   U.S.  Government  Fund will generally  value  securities at market value,  if
available.  If market value is not  available,  the Fund will value  securities,
other than  securities  with 60 days or less to maturity as discussed  below, at
prices based on market quotations for securities of similar type, yield, quality
and duration.
   
   Valuations  furnished by the pricing  service with respect to Municipal  Bond
Fund's municipal  securities are based upon appraisals from recognized municipal
securities dealers derived from information  concerning market  transactions and
quotations.  Securities for which market  quotations  are readily  available are
valued at the last  reported  sale price,  or, if no sales are  reported on that
day, at the mean between the latest  available bid and asked prices.  Securities
for which market  quotations  are not readily  available  (which are expected to
constitute  the  majority of Municipal  Bond Fund's  portfolio  securities)  are
valued  at  the  best  available  current  bid  price  by the  pricing  service,
considering  such factors as yields or prices of municipal  bonds of  comparable
quality,  type of issue,  coupon,  maturity and rating,  indications as to value
from dealers,  and general market  conditions.  The Fund's  officers,  under the
general supervision of the Board of Directors,  will regularly review procedures
used by, and valuations provided by, the pricing service.  Municipal Bond Fund's
taxable short-term  securities for which market quotations are readily available
will be valued at market value,  which is the last reported sale price or, if no
sales are reported on that day, at the mean between the latest available bid and
asked prices except that securities having 60 days or less remaining to maturity
may be valued at their amortized cost as discussed below.
    
   Cash Fund's  securities are valued by the amortized cost valuation  technique
which does not take into consideration unrealized gains or losses. The amortized
cost  valuation  technique  involves  valuing  an  instrument  at its  cost  and
thereafter  assuming a constant  amortization  to  maturity  of any  discount or
premium  regardless of the impact of  fluctuating  interest  rates on the market
value of the instrument.  While this method provides certainty in valuation,  it
may result in periods  during which value,  as determined by amortized  cost, is
higher  or  lower  than  the  price  Cash  Fund  would  receive  if it sold  the
instrument.

                                       44
<PAGE>
   During periods of declining interest rates, the daily yield on shares of Cash
Fund computed as described  above may tend to be higher than a like  computation
made by a fund with identical  investments utilizing a method of valuation based
upon  market  prices and  estimates  of market  prices for all of its  portfolio
instruments.  Thus, if the use of amortized  cost by Cash Fund resulted in lower
aggregate  portfolio  value on a particular  day, a prospective  investor in the
Fund would be able to obtain a somewhat  higher  yield  than would  result  from
investment in a fund  utilizing  solely market values and existing  investors in
Cash Fund would receive less  investment  income.  The converse would apply in a
period of rising interest rates.

   The use of amortized  cost and the  maintenance  of Cash Fund's per share net
asset value at $1.00 is based on its election to operate under the provisions of
Rule 2a-7 under the Investment  Company Act of 1940. As a condition of operating
under that rule,  the Fund must  maintain a  dollar-weighted  average  portfolio
maturity  of 90  days  or  less,  purchase  only  instruments  having  remaining
maturities of thirteen  months or less, and invest only in securities  which are
determined by the Board of Directors to present  minimal  credit risks and which
are of high quality as determined by any major rating service, or in the case of
any  instrument  not so rated,  considered  by the Board of  Directors  to be of
comparable quality.

   The Board of Directors has established  procedures  designed to maintain Cash
Fund's price per share, as computed for the purpose of sales and redemptions, at
$1.00.  These procedures include a review of the Fund's holdings by the Board of
Directors at such intervals as they deem  appropriate  to determine  whether the
Fund's net asset value calculated by using available market quotations  deviates
from $1.00 per share based on amortized  cost. If any  deviation  exceeds 1/2 of
1%, the Board of Directors will promptly  consider what action,  if any, will be
initiated.  In the event  the Board of  Directors  determines  that a  deviation
exists  which  may  result in  material  dilution  or other  unfair  results  to
investors  or existing  shareholders,  they have agreed to take such  corrective
action as they regard as necessary and  appropriate,  including the sale of Cash
Fund  instruments  prior  to  maturity  to  shorten  average  Fund  maturity  or
withholding  dividends.  Cash  Fund  will use its best  efforts  to  maintain  a
constant net asset value per share of $1.00.  See "Security Cash Fund," page 12,
and "Dividends and Taxes," page 48. Since  dividends from net investment  income
will be accrued  daily and paid  monthly,  the net asset value per share of Cash
Fund will ordinarily  remain at $1.00,  but the Fund's daily dividends will vary
in amount.
   
   U.S.  Government  Fund and  Municipal  Bond Fund may use the  amortized  cost
valuation  technique  utilized by Cash Fund for securities with maturities of 60
days or less. In addition,  U.S.  Government  and Municipal Bond Funds may use a
similar  procedure for  securities  having 60 days or less remaining to maturity
with the value of the security on the 61st day being used rather than the cost.
    
   The Funds will accept  orders from  dealers on each  business  day up to 4:30
p.m. (Central time).

HOW TO REDEEM SHARES

   A stockholder may redeem shares at the net asset value next determined  after
such shares are tendered for redemption. The amount received may be more or less
than the  investor's  cost,  depending  upon the market  value of the  portfolio
securities at the time of redemption.

   Shares will be redeemed on request of the  stockholder in proper order to the
Investment Manager, which serves as the Funds' transfer agent. A request is made
in proper order by submitting the following items to the Investment Manager: (1)
a written request for redemption  signed by all registered owners exactly as the
account is registered,  including  fiduciary  titles, if any, and specifying the
account  number and the dollar amount or number of shares to be redeemed;  (2) a
guarantee of all signatures on the written  request or on the share  certificate
or accompanying  stock power; (3) any share  certificates  issued for any of the
shares to be redeemed; and (4) any additional documents which may be required by
the Investment  Manager for redemption by corporations  or other  organizations,
executors, administrators,  trustees, custodians or the like. Transfers of share
ownership  are subject to the same  requirements.  A signature  guarantee is not
required  for  redemptions  of $10,000 or less,  requested by and payable to all
stockholders of record for an account,  to be sent to the address of record. The
signature guarantee must be provided by an eligible guarantor institution,  such
as a bank,  broker,  credit  union,  national  securities  exchange  or  savings
association.  The Investment  Manager reserves the right to reject any signature
guarantee pursuant to its written procedures which may be revised in the future.
To avoid delay in redemption or transfer,  stockholders  having questions should
contact the Investment Manager.

   The amount due on redemption,  will be the net asset value of the shares next
computed  after the  redemption  request  in  proper  order is  received  by the
Investment  Manager less any  applicable  deferred  sales  charge.  In addition,
stockholders of Cash Fund will receive any  undistributed  dividends,  including
any dividend declared on

                                       45
<PAGE>
the day of the redemption. Payment of the redemption price will be made by check
(or by wire at the sole discretion of the Investment Manager if wire transfer is
requested,  including name and address of the bank and the stockholder's account
number to which  payment is to be wired)  within seven days after receipt of the
redemption   request  in  proper  order.   The  check  will  be  mailed  to  the
stockholder's registered address (or as otherwise directed).  Remittance by wire
(to a commercial  bank account in the same name(s) as the shares are registered)
or by express  mail,  if  requested,  will be at a charge of $15,  which will be
deducted from the redemption proceeds.

   Cash Fund offers  redemption  by check.  If blank checks are requested on the
Check Writing  Request form, the Fund will make a supply  available.  Checks for
the Cash Fund may be drawn  payable  to the order of any payee  (not to cash) in
any  amount of $100 or more.  Checks may be cashed or  deposited  like any other
check drawn on a bank.  When a check is presented  to the Fund for  payment,  it
will  redeem  sufficient  full and  fractional  shares to cover the check.  Such
shares will be redeemed at the price next  calculated  following  receipt of any
check  which does not exceed  the value of the  account.  The price of Cash Fund
shares may fluctuate from day-to-day and the price at the time of redemption, by
check or otherwise,  may be less than the amount  invested.  Any check presented
for payment which is more than the value of the account will be returned without
payment,  marked  "Insufficient  Funds."  Each new  stockholder  will  initially
receive  twelve  checks  free of  charge  and such  additional  checks as may be
required.  Since the amount available for withdrawal fluctuates daily, it is not
practical  for a  stockholder  to attempt to withdraw the entire  investment  by
check.  The Fund  reserves the right to terminate  this service at any time with
respect to existing as well as future  stockholders.  Redemption by check is not
available if any shares are held in certificate form or if shares being redeemed
have not been on the Fund's books for at least 15 days.

   When investing in the Funds,  stockholders  are required to furnish their tax
identification  number  and  to  state  whether  or  not  they  are  subject  to
withholding  for prior  underreporting,  certified under penalties of perjury as
prescribed by the Internal  Revenue  Code.  To the extent  permitted by law, the
redemption proceeds of stockholders who fail to furnish this information will be
reduced by $50 to  reimburse  for the IRS penalty  imposed for failure to report
the tax identification number on information reports.

   Payment in cash of the amount due on redemption, less any applicable deferred
sales charge,  for shares  redeemed will be made within seven days after tender,
except that the Funds may suspend the right of redemption during any period when
trading on the New York Stock  Exchange is restricted or such Exchange is closed
for other than weekends or holidays,  or any emergency is deemed to exist by the
Securities and Exchange Commission.  When a redemption request is received,  the
redemption  proceeds are deposited into a redemption account  established by the
Distributor  and the  Distributor  sends a check  in the  amount  of  redemption
proceeds  to the  stockholder.  The  Distributor  earns  interest on the amounts
maintained  in  the  redemption  account.  Conversely,  the  Distributor  causes
payments  to be made to the Funds in the case of  orders  for  purchase  of Fund
shares before it actually receives federal funds.

   In addition  to the  foregoing  redemption  procedure,  the Funds  repurchase
shares from  broker/dealers  at the price determined as of the close of business
on the day such  offer is  confirmed.  Dealers  may charge a  commission  on the
repurchase of shares.

   The  repurchase or redemption  of shares held in a  tax-qualified  retirement
plan must be effected  through the trustee of the plan and may result in adverse
tax consequences. (See "Retirement Plans," page 59.)

   At various  times the Funds may be requested to redeem  shares for which they
have not yet received good payment. Accordingly, the Funds may delay the mailing
of a redemption check until such time as they have assured  themselves that good
payment  (e.g.,  cash or certified  check on a U.S. bank) has been collected for
the  purchase  of such  shares,  which may take up to 15 days from the  purchase
date.
   
   Municipal  Bond Fund's  Articles of  Incorporation  provide that, in order to
minimize  expenses,  the Fund  may,  pursuant  to a  resolution  of the Board of
Directors,  adopt a procedure  whereby it would redeem  stockholder  accounts in
which  there  are  fewer  than 50  shares  (or such  lesser  amount as the board
determines) after having given the stockholders at least 60 days' written notice
and an opportunity to increase the account to at least 50 shares. This procedure
can be implemented only after six months' prior notice to all stockholders  that
the  procedure  will be put into effect.  The Board of Directors  has no present
plan to implement an involuntary redemption procedure.
    
                                       46
<PAGE>
TELEPHONE REDEMPTIONS

   Stockholders of the Funds may redeem  uncertificated  shares in amounts up to
$10,000 by telephone  request,  provided that the  stockholder has completed the
Telephone  Redemption section of the application or a Telephone  Redemption form
which may be obtained from the Investment  Manager.  The proceeds of a telephone
redemption will be sent to the stockholder at his or her address as set forth in
the application or in a subsequent written authorization. Once authorization has
been received by the  Investment  Manager,  a  stockholder  may redeem shares by
calling  the  Funds at (800)  888-2461,  extension  3127,  on  weekdays  (except
holidays) between the hours of 7:00 a.m. and 6:00 p.m. Central time.  Redemption
requests  received by telephone  after the close of the New York Stock  Exchange
(normally  3:00 p.m.  Central  time) will be treated as if  received on the next
business  day.  Telephone  redemptions  are not accepted  for IRA and  403(b)(7)
accounts.  A stockholder  who authorizes  telephone  redemptions  authorizes the
Investment  Manager  to act  upon the  instructions  of any  person  identifying
themselves  as the owner of the account or the owner's  broker.  The  Investment
Manager has established procedures to confirm that instructions  communicated by
telephone  are  genuine and will be liable for any losses due to  fraudulent  or
unauthorized  instructions  if it  fails to  comply  with  its  procedures.  The
Investment  Manager's procedures require that any person requesting a redemption
by  telephone  provide the  account  registration  and  number,  the owner's tax
identification number, and the dollar amount or number of shares to be redeemed,
and such instructions must be received on a recorded line. Neither the Fund, the
Investment Manager, nor the Distributor will be liable for any loss,  liability,
cost  or  expense  arising  out of any  redemption  request  provided  that  the
Investment  Manager  complied  with its  procedures.  Thus,  a  stockholder  who
authorizes telephone  redemptions may bear the risk of loss from a fraudulent or
unauthorized  request.  The  telephone  redemption  privilege  may be changed or
discontinued at any time by the Investment Manager or the Funds.

   During periods of severe market or economic conditions, telephone redemptions
may be difficult to implement and  stockholders  should make redemptions by mail
as described under "How to Redeem Shares," page 45.

HOW TO EXCHANGE SHARES

   Pursuant to arrangements with the Distributor,  stockholders of the Funds may
exchange  their shares for shares of another of the Funds,  or for shares of the
other mutual funds  distributed  by the  Distributor,  which  currently  include
Security Equity,  Growth and Income,  Global,  Ultra,  Asset Allocation,  Social
Awareness,  Emerging  Markets Total Return,  Global Asset  Allocation and Global
High Yield Funds. Such transactions  generally have the same tax consequences as
ordinary sales and purchases and are not tax-free exchanges.

   Class A and  Class B shares of the  Funds  may be  exchanged  for Class A and
Class B  shares,  respectively,  of  another  of the  funds  distributed  by the
Distributor  or for shares of Cash Fund,  which offers a single class of shares.
Any applicable contingent deferred sales charge will be calculated from the date
of the  initial  purchase  without  regard to the time  shares were held in Cash
Fund.

   Because Cash Fund does not impose a sales charge in connection  with sales of
its shares, any exchange of Cash Fund shares acquired through direct purchase or
reinvestment  of dividends will be based upon the respective net asset values of
the shares involved next determined after the exchange is accepted,  and a sales
charge will be imposed equal to the sales charge that would be applicable if the
stockholder  were  purchasing  shares of the other Fund  involved for cash.  The
amount  of  such  sales  charge  will be paid  by  Cash  Fund on  behalf  of the
exchanging  stockholder  directly to the  Distributor and the net asset value of
the shares being exchanged will be reduced by a like amount.

   Stockholders  making such exchanges must provide the Investment  Manager with
sufficient information to permit verification of their prior ownership of shares
of one of the other Security Funds.  Shares of Cash Fund begin earning dividends
on the day after the date an  exchange  into such shares is  effected.  Any such
exchange is subject to the minimum  investment and  eligibility  requirements of
each Fund. No service fee is presently imposed on such an exchange.

   Exchanges  may  be  accomplished  by  submitting  a  written  request  to the
Investment   Manager,   700  Harrison   Street,   Topeka,   Kansas   66636-0001.
Broker/dealers  who process  exchange  orders on behalf of their  customers  may
charge a fee for their  services.  Such fee would be in  addition  to any of the
sales or other charges  referred to above but may be avoided by making  exchange
requests  directly to the Investment  Manager.  Due to the high cost of exchange
activity and the  maintenance of accounts  having a net value of less than $100,
Cash Fund reserves

                                       47

the right to totally  convert  the  account if at any time an  exchange  request
results in an account being lowered below the $100 minimum.

   An exchange of shares, as described above, may result in the realization of a
capital gain or loss for federal  income tax purposes,  depending on the cost or
other value of the shares  exchanged.  No  representation  is made as to whether
gain or loss would  result from any  particular  exchange or as to the manner of
determining  the amount of gain or loss.  (See  "Dividends and Taxes," page 48.)
Before effecting any exchange  described  herein,  the investor may wish to seek
the advice of a financial or tax adviser.

   Exchanges  of shares of the  Funds  may be made only in  jurisdictions  where
shares  of  the  fund  being  acquired  may  lawfully  be  sold.  More  complete
information about the other Security Funds,  including charges and expenses, are
contained  in the current  prospectus  describing  each Fund.  Stockholders  are
advised to obtain and  review  carefully,  the  applicable  prospectus  prior to
effecting any exchange.  A copy of such  prospectus will be given any requesting
stockholder by the Distributor.

   The  exchange  privilege  may be  changed  or  discontinued  any  time at the
discretion of the management of the Funds upon 60 days' notice to  stockholders.
It is contemplated, however, that this privilege will be extended in the absence
of objection by regulatory  authorities  and provided that shares of the various
funds are available and may be lawfully  sold in the  jurisdiction  in which the
stockholder resides.

EXCHANGE BY TELEPHONE

   To exchange shares by telephone, a stockholder must have completed either the
Telephone   Exchange  section  of  the  application  or  a  Telephone   Transfer
Authorization   form  which  may  be  obtained  from  the  Investment   Manager.
Authorization  must be on file with the Investment  Manager before exchanges may
be made by telephone.  Once  authorization  has been received by the  Investment
Manager,  a stockholder may exchange shares by telephone by calling the Funds at
(800) 888-2461,  extension 3127, on weekdays (except holidays) between the hours
of 7:00 a.m. and 6:00 p.m. Central time. Exchange requests received by telephone
after the close of the New York Stock Exchange (normally 3:00 p.m. Central time)
will be treated as if received on the next business  day.  Shares which are held
in certificate  form may not be exchanged by telephone.  The telephone  exchange
privilege is only permitted  between accounts with identical  registration.  The
Investment  Manager has  established  procedures  to confirm  that  instructions
communicated  by telephone  are genuine and will be liable for any losses due to
fraudulent  or  unauthorized  instructions,  if it  fails  to  comply  with  its
procedures.   The  Investment  Manager's  procedures  require  that  any  person
requesting an exchange by telephone provide the account registration and number,
the tax  identification  number,  the  dollar  amount  or number of shares to be
exchanged,  and the names of the  Security  Funds  from which and into which the
exchange  is to be made,  and such  instructions  must be received on a recorded
line.  Neither the Funds,  the Investment  Manager,  nor the Distributor will be
liable for any loss,  liability,  cost or expense  arising  out of any  request,
including any fraudulent  request provided the Investment  Manager complied with
its procedures.  Thus, a stockholder who authorizes telephone exchanges may bear
the risk of loss from a  fraudulent  or  unauthorized  request.  This  telephone
exchange  privilege may be changed or discontinued at any time at the discretion
of the management of the Funds.  In particular,  the Funds may set limits on the
amount and frequency of such  exchanges,  in general or as to any individual who
abuses such privilege.

DIVIDENDS AND TAXES

   The following summarizes certain federal income tax considerations  generally
affecting  the Funds and their  stockholders.  No  attempt  is made to present a
detailed  explanation  of the tax treatment of the Funds or their  stockholders,
and  the  discussion  here is not  intended  as a  substitute  for  careful  tax
planning.  The  discussion  is based upon  present  provisions  of the  Internal
Revenue  Code of 1986,  as amended (the  "Code"),  the  regulations  promulgated
thereunder, and judicial and administrative ruling authorities, all of which are
subject to change, which change may be retroactive. Prospective investors should
consult  their own tax advisors with regard to the federal tax  consequences  of
the purchase  ownership,  and  disposition  of Fund  shares,  as well as the tax
consequences  arising  under the laws of any state,  foreign  country,  or other
taxing jurisdiction.

   Each  Fund  intends  to  qualify  annually  and to elect to be  treated  as a
regulated investment company under the Internal Revenue Code of 1986, as amended
(the  "Code").  To qualify as a regulated  investment  company,  each Fund must,
among other  things:  (i) derive in each  taxable year at least 90% of its gross
income from  dividends,  interest,  payments with respect to certain  securities
loans, and gains from the sale or other disposition of stock,

                                       48
<PAGE>
securities or foreign  currencies,  or other income  derived with respect to its
business of  investing in such stock,  securities,  or  currencies  ("Qualifying
Income  Test");  (ii) diversify its holdings so that, at the end of each quarter
of the taxable  year,  (a) at least 50% of the market value of the Fund's assets
is represented by cash, cash items, U.S. Government  securities,  the securities
of other regulated investment companies,  and other securities,  with such other
securities of any one issuer limited for the purposes of this  calculation to an
amount not greater  than 5% of the value of the Fund's  total  assets and 10% of
the outstanding  voting securities of such issuer,  and (b) not more than 25% of
the value of its total  assets is invested in the  securities  of any one issuer
(other than U.S.  Government  securities or the  securities  of other  regulated
investment  companies),  or of two or more issuers  which the Fund  controls (as
that  term is  defined  in the  relevant  provisions  of the Code) and which are
determined to be engaged in the same or similar  trades or businesses or related
trades  or  businesses;  and  (iii)  distribute  at least  90% of the sum of its
investment company taxable income (which includes, among other items, dividends,
interest,  and net  short-term  capital  gains in  excess  of any net  long-term
capital losses) and its net tax-exempt  interest each taxable year. The Treasury
Department is authorized to promulgate  regulations under which foreign currency
gains would constitute  qualifying  income for purposes of the Qualifying Income
Test only if such gains are  directly  related to investing  in  securities  (or
options and futures with respect to  securities).  To date, no such  regulations
have been issued.

   A Fund  qualifying as a regulated  investment  company  generally will not be
subject to U.S. federal income tax on its investment  company taxable income and
net  capital  gains  (any  net  long-term  capital  gains in  excess  of the net
short-term  capital losses),  if any, that it distributes to shareholders.  Each
Fund intends to distribute to its stockholders, at least annually, substantially
all of its investment company taxable income and any net capital gains.

   Generally,  regulated investment  companies,  like the Funds, must distribute
amounts  on a timely  basis in  accordance  with a  calendar  year  distribution
requirement in order to avoid a nondeductible 4% excise tax. Generally, to avoid
the tax, a regulated  investment  company must  distribute  during each calendar
year,  (i) at least 98% of its  ordinary  income (not  taking  into  account any
capital gains or losses) for the calendar year, (ii) at least 98% of its capital
gains in excess of its capital losses (adjusted for certain ordinary losses) for
the 12-month  period  ending on October 31 of the calendar  year,  and (iii) all
ordinary  income and capital gains for previous years that were not  distributed
during such years. To avoid  application of the excise tax, each Fund intends to
make its  distributions  in  accordance  with  the  calendar  year  distribution
requirement.  A distribution,  including an "exempt-interest  dividend," will be
treated as paid on December 31 of the calendar  year if it is declared by a Fund
in October,  November or  December of that year to  shareholders  of record on a
date in such a month  and  paid by the  Fund  during  January  of the  following
calendar year.  Such  distributions  are taxable to shareholders in the calendar
year in which the distributions  are declared,  rather than the calendar year in
which the distributions are received.

   If, as a result of exchange  controls or other  foreign laws or  restrictions
regarding  repatriation  of capital,  a Fund were unable to distribute an amount
equal  to  substantially  all of  its  investment  company  taxable  income  (as
determined for U.S. tax purposes) within applicable time periods, the Fund would
not qualify for the favorable  federal income tax treatment  afforded  regulated
investment companies,  or, even if it did so qualify, it might become liable for
federal taxes on  undistributed  income.  In addition,  the ability of a Fund to
obtain  timely  and  accurate  information  relating  to  its  investments  is a
significant  factor in complying with the  requirements  applicable to regulated
investment  companies in making tax-related  computations.  Thus, if a Fund were
unable to obtain  accurate  information on a timely basis, it might be unable to
qualify as a regulated  investment  company,  or its tax  computations  might be
subject to revisions  (which could result in the  imposition of taxes,  interest
and penalties).
   
   It is the policy of Corporate Bond,  Limited Maturity Bond, U.S.  Government,
High Yield and Municipal Bond Funds to pay dividends from net investment  income
monthly. It is the policy of the Funds to make distributions of realized capital
gains (if any) in excess of any capital  losses and capital loss  carryovers  at
least once a year. Because Class A shares of the Funds bear most of the costs of
distribution of such shares through  payment of a front-end sales charge,  while
Class B shares of the Funds bear such costs through a higher  distribution  fee,
expenses  attributable  to Class B shares,  generally  will be  higher  and as a
result,  income  distributions  paid by the Funds with respect to Class B shares
generally  will be lower  than those  paid with  respect to Class A shares.  All
dividends and distributions are automatically  reinvested on the payable date in
shares of the Fund at net asset  value,  as of the record  date  (reduced  by an
amount  equal  to the  amount  of the  dividend  or  distribution),  unless  the
Investment  Manager is previously  notified in writing by the  stockholder  that
such dividends or  distributions  are to be received in cash. A stockholder  may
request that such dividends or distributions be

                                       49
<PAGE>
directly  deposited to the stockholder's bank account. A stockholder who elected
not to reinvest  dividends or distributions  paid with respect to Class A shares
may,  at any time  within  thirty  days after the  payment  date,  reinvest  the
dividend check without imposition of a sales charge.
    
   Cash Fund's policy is to declare daily dividends of all of its net investment
income each day the Fund is open for  business,  increased  or  decreased by any
realized capital gains or losses.  Such dividends are automatically  credited to
stockholder  accounts.  Unless  stockholders  elect to receive  cash,  they will
receive such  dividends in additional  shares on the first  business day of each
month at the net asset  value on that date.  If cash is desired,  investors  may
indicate so in the  appropriate  section of the  application  and checks will be
mailed within five business days after the beginning of the month. The amount of
dividend may fluctuate from day to day. If on any day net realized or unrealized
losses on  portfolio  securities  exceed  Cash  Fund's  income  for that day and
results in a decline of net asset value per share below $1.00,  the dividend for
that day will be  omitted  until  the net asset  value  per  share  subsequently
returns to $1.00 per share.
   
   The Funds will not pay  dividends or  distributions  of less than $25 in cash
but will automatically reinvest them. Distributions of net investment income and
any short-term capital gains by Income Fund or Cash Fund are taxable as ordinary
income  whether  received in cash or  reinvested in  additional  shares.  To the
extent that  Municipal  Bond Fund's  dividends  are derived from interest on its
temporary taxable  investments or from an excess of net short-term  capital gain
over net long-term  capital loss,  its dividends are taxable as ordinary  income
whether received in cash or reinvested in additional  shares.  Such dividends do
not qualify for the dividends-received deduction for corporations.

   Distributions of net capital gain,  whether received in cash or reinvested in
Fund shares,  will generally be taxable to  shareholders as either "20% Gain" or
"28% Gain",  depending upon the Fund's holding period for the assets sold.  "20%
Gains" arise from sales of assets held by a Fund for more than 18 months and are
subject to a maximum  tax rate of 20%;  "28%  Gains"  arise from sales of assets
held by a Fund for more than one year but no more than 18 months and are subject
to a maximum tax rate of 28%. Net capital gains from assets held for one year or
less will be taxed as ordinary  income.  Distributions  will be subject to these
capital gains rates  regardless of how long a shareholder  has held Fund shares.
Because Cash Fund normally  will not invest in  securities  having a maturity of
more than one year, it should not realize any long-term capital gains or losses.
Advice as to the tax status of each year's dividends and  distributions  will be
mailed annually.

   Municipal Bond Fund intends to qualify to pay "exempt-interest  dividends" to
its stockholders. The Fund will be so qualified if, at the close of each quarter
of its taxable year,  at least 50% of the value of its total assets  consists of
securities  on which the  interest  payments are exempt from federal tax. To the
extent that Municipal Bond Fund's  dividends  distributed  to  stockholders  are
derived  from  earnings  on  interest  income  exempt  from  federal tax and are
designated as  "exempt-interest  dividends" by the Fund, they will be excludable
from a  stockholder's  gross income for federal  income tax purposes.  Municipal
Bond Fund will  inform  stockholders  annually  as to the portion of that year's
distributions from the Fund which constituted "exempt-interest dividends."

   Federal  tax law  imposes an  alternative  minimum  tax with  respect to both
corporations and individuals based on certain items of tax preference.  Interest
on certain municipal obligations, such as bonds issued to make loans for housing
purposes or to private  entities  (but not to certain  tax-exempt  organizations
such as  universities  and  non-profit  hospitals) is included as an item of tax
preference in determining the amount of a taxpayer's alternative minimum taxable
income.  To the extent that the Fund receives income from municipal  obligations
treated as a tax preference item for purposes of the alternative  minimum tax, a
portion of the  dividends  paid by it,  although  otherwise  exempt from federal
income  tax,  will be  taxable  to  shareholders  to the  extent  that their tax
liability will be determined  under the  alternative  minimum tax. The Fund will
annually  supply  shareholders  with a report  indicating the percentage of Fund
income attributable to municipal  obligations subject to the alternative minimum
tax.  Additionally,  taxpayers must disclose to the Internal  Revenue Service on
their  tax  returns  the  entire  amount  of  tax-exempt   interest   (including
exempt-interest  dividends on shares of the Fund) received or accrued during the
year.

   In addition,  for  corporations,  the  alternative  minimum taxable income is
increased  by a  percentage  of the  amount by which an  alternative  measure of
income ("adjusted  current  earnings",  referred to as "ACE") exceeds the amount
otherwise  determined to be the alternative minimum taxable income.  Interest on
all municipal obligations,  and therefore all exempt-interest  dividends paid by
the Fund, is included in calculating  ACE.  Taxpayers that may be subject to the
alternative  minimum tax should consult their tax advisers  before  investing in
the Municipal Bond Fund.

                                       50
<PAGE>
   To the extent that Municipal Bond Fund's  interest  income is attributable to
private activity bonds,  dividends  allocable to such income,  while exempt from
the regular  federal  income tax, may  constitute an item of tax  preference for
purposes of the alternative minimum tax. In addition, for corporate stockholders
of  Municipal  Bond  Fund,  exempt  interest  may  comprise  part  or  all of an
adjustment to alternative minimum taxable income.
    
   Stockholders of the Funds who redeem their shares generally will realize gain
or loss upon the sale or redemption (including the exchange of shares for shares
of another  fund)  which will be capital  gain or loss if the shares are capital
assets in the  stockholder's  hands, and will be taxable to stockholders as "20%
Gains" if the shares had been held for more than 18 months or as "28%  Gains" if
the  shares  had been held for more  than one year but no more  than 18  months.
Investors  should be aware that any loss realized upon the sale or redemption of
shares held for six months or less will be treated as a long-term  capital  loss
to the extent of any  distribution of long-term  capital gain to the stockholder
with  respect  to such  shares.  In  addition,  any loss  realized  on a sale or
exchange of shares will be disallowed  to the extent the shares  disposed of are
replaced within a period of 61 days, beginning 30 days before and ending 30 days
after the date the shares are disposed of, such as pursuant to the  reinvestment
of dividends. In such case, the basis of the shares acquired will be adjusted to
reflect the disallowed loss.

   Under certain  circumstances,  the sales charge incurred in acquiring Class A
shares of a Fund may not be taken into account in  determining  the gain or loss
on the  disposition  of those shares.  This rule applies in  circumstances  when
shares  of the Fund are  exchanged  within  90 days  after  the date  they  were
purchased and new shares in a regulated  investment company are acquired without
a sales  charge or at a reduced  sales  charge.  In that case,  the gain or loss
recognized on the exchange will be determined by excluding from the tax basis of
the shares  exchanged all or a portion of the sales charge incurred in acquiring
those shares. This exclusion applies to the extent that the otherwise applicable
sales charge with respect to the newly acquired shares is reduced as a result of
having incurred the sales charge  initially.  Instead,  the portion of the sales
charge  affected  by this rule  will be  treated  as an amount  paid for the new
shares.
   
   Up to 85% of an individual's  Social Security  benefits and certain  railroad
retirement  benefits  may be  subject to federal  income  tax.  Along with other
factors,  total  tax-exempt  income,  including  any  exempt-interest  dividends
received  from  Municipal  Bond Fund, is used to calculate the portion of Social
Security benefits that is taxed.
    
   Under the  Internal  Revenue  Code,  a  stockholder  may not  deduct all or a
portion of interest on  indebtedness  incurred or continued to purchase or carry
shares of an investment company paying exempt-interest  dividends.  In addition,
under rules issued by the Internal Revenue Service for determining when borrowed
funds are considered used for the purposes of purchasing or carrying  particular
assets, the purchase of shares may be considered to have been made with borrowed
funds even though the borrowed funds are not directly  traceable to the purchase
of shares.
   
   A  deductible  "environmental  tax" of 0.12% is  imposed  on a  corporation's
modified  alternative  minimum  taxable  income  in excess  of $2  million.  The
environmental tax will be imposed even if the corporation is not required to pay
an  alternative  minimum  tax  because  the  corporation's  regular  income  tax
liability exceeds its minimum tax liability.  To the extent that exempt-interest
dividends  paid by  Municipal  Bond Fund are  included  in  alternative  minimum
taxable income, corporate stockholders may be subject to the environmental tax.

   Opinions  relating to the validity of municipal  securities and the exemption
of interest  thereon from federal income tax are rendered by bond counsel to the
issuer.  Neither the Investment  Manager nor Municipal Bond Fund's counsel makes
any review of  proceedings  relating to the issuance of municipal  securities or
the bases of such opinions.
    
   The Funds are  required  by law to  withhold  31% of  taxable  dividends  and
distributions  to  stockholders  who  do  not  furnish  their  correct  taxpayer
identification  numbers,  or are  otherwise  subject to the  backup  withholding
provisions of the Internal Revenue Code.

   Each of Corporate Bond Fund, Limited Maturity Bond Fund, U.S. Government Fund
and High Yield Fund (the Series of Income  Fund) will be treated  separately  in
determining  the amounts of income and  capital  gains  distributions.  For this
purpose, each Fund will reflect only the income and gains, net of losses of that
Fund.

   A purchase of shares  shortly  before  payment of a dividend or  distribution
would be  disadvantageous  because the dividend or distribution to the purchaser
would have the effect of  reducing  the per share net asset  value of his or her
shares by the amount of the  dividends  or  distributions.  In addition all or a
portion  of such  dividends  or  distributions,  although  in effect a return of
capital, are subject to taxes, which may be at ordinary income tax rates.

                                       51
<PAGE>
   OPTIONS, FUTURES AND FORWARD CONTRACTS AND SWAP AGREEMENTS.  Certain options,
futures  contracts,  and  forward  contracts  in which a Fund may  invest may be
"Section 1256  contracts."  Gains or losses on Section 1256 contracts  generally
are  considered  60%  long-term  and 40%  short-term  capital  gains or  losses;
however,  foreign  currency  gains or losses  arising from certain  Section 1256
contracts  may be  treated  as  ordinary  income  or loss.  Also,  Section  1256
contracts  held by a Fund at the end of each taxable year (and at certain  other
times as prescribed pursuant to the Code) are "marked to market" with the result
that unrealized gains or losses are treated as though they were realized.

   Generally,  the  hedging  transactions  undertaken  by a Fund may  result  in
"straddles" for U.S. federal income tax purposes.  The straddle rules may affect
the  character  of gains (or losses)  realized by a Fund.  In  addition,  losses
realized  by a Fund on  positions  that are part of a straddle  may be  deferred
under the straddle  rules,  rather than being taken into account in  calculating
the  taxable  income for the  taxable  year in which such  losses are  realized.
Because  only a few  regulations  implementing  the  straddle  rules  have  been
promulgated,  the tax consequences of transactions in options,  futures, forward
contracts,  swap  agreements  and other  financial  contracts  to a Fund are not
entirely clear. The  transactions may increase the amount of short-term  capital
gain realized by a Fund which is taxed as ordinary  income when  distributed  to
shareholders.

   A Fund may make one or more of the elections  available  under the Code which
are applicable to straddles.  If a Fund makes any of the elections,  the amount,
character  and timing of the  recognition  of gains or losses from the  affected
straddle  positions  will be determined  under rules that vary  according to the
election(s)  made.  The rules  applicable  under  certain of the  elections  may
operate to  accelerate  the  recognition  of gains or losses  from the  affected
straddle positions.

   Because  application  of the straddle rules may affect the character of gains
or losses,  defer losses and/or  accelerate  the  recognition of gains or losses
from the affected  straddle  positions,  the amount which must be distributed to
shareholders,  and which will be taxed to  shareholders  as  ordinary  income or
long-term capital gain, may be increased or decreased as compared to a fund that
did not engage in such hedging transactions.

   Because only a few  regulations  regarding the treatment of swap  agreements,
and  related  caps,  floors  and  collars,   have  been  implemented,   the  tax
consequences of such  transactions  are not entirely clear.  The Funds intend to
account for such transactions in a manner deemed by them to be appropriate,  but
the Internal Revenue Service might not necessarily accept such treatment.  If it
did  not,  the  status  of a Fund as a  regulated  investment  company  might be
affected.

   The  requirements  applicable  to  a  Fund's  qualification  as  a  regulated
investment  company  may limit the extent to which a Fund will be able to engage
in  transactions  in  options,  futures  contracts,   forward  contracts,   swap
agreements and other financial contracts.

   MARKET  DISCOUNT.  If a Fund  purchases a debt security at a price lower than
the  stated  redemption  price of such debt  security,  the excess of the stated
redemption price over the purchase price is "market discount".  If the amount of
market  discount  is more than a DE MINIMIS  amount,  a portion  of such  market
discount  must be included as ordinary  income (not capital gain) by the Fund in
each taxable  year in which the Fund owns an interest in such debt  security and
receives a principal payment on it. In particular,  the Fund will be required to
allocate that principal  payment first to the portion of the market  discount on
the debt security  that has accrued but has not  previously  been  includable in
income. In general, the amount of market discount that must be included for each
period is equal to the  lesser of (i) the  amount  of market  discount  accruing
during  such period  (plus any accrued  market  discount  for prior  periods not
previously taken into account) or (ii) the amount of the principal  payment with
respect to such period. Generally,  market discount accrues on a daily basis for
each day the debt  security  is held by a Fund at a constant  rate over the time
remaining to the debt security's  maturity or, at the election of the Fund, at a
constant yield to maturity which takes into account the semi-annual  compounding
of interest.  Gain realized on the disposition of a market  discount  obligation
must be recognized as ordinary  interest income (not capital gain) to the extent
of the "accrued market discount."

   ORIGINAL ISSUE DISCOUNT. Certain debt securities acquired by the Funds may be
treated as debt  securities  that were  originally  issued at a  discount.  Very
generally,  original  issue  discount is defined as the  difference  between the
price  at  which a  security  was  issued  and its  stated  redemption  price at
maturity.  Although  no cash  income on account  of such  discount  is  actually
received by a Fund, original issue discount that accrues on a debt security in a
given year generally is treated for federal income tax purposes as interest and,
therefore,  such  income  would  be  subject  to the  distribution  requirements
applicable to regulated investment companies.

                                       52
<PAGE>
   Some debt securities may be purchased by the Funds at a discount that exceeds
the original issue  discount on such debt  securities,  if any. This  additional
discount represents market discount for federal income tax purposes (see above).

   CONSTRUCTIVE  SALES.  Recently  enacted  rules  may  affect  the  timing  and
character of gain if a Fund engages in transactions that reduce or eliminate its
risk of loss with respect to appreciated financial positions. If the Fund enters
into certain  transactions  in property  while holding  substantially  identical
property,  the  Fund  would  be  treated  as  if it  had  sold  and  immediately
repurchased  the  property and would be taxed on any gain (but no loss) from the
constructive  sale. The character of gain from a constructive  sale would depend
upon the Fund's  holding period in the property.  Loss from a constructive  sale
would be  recognized  when the  property was  subsequently  disposed of, and its
character  would  depend on the Fund's  holding  period and the  application  of
various loss deferral provisions of the Code.

   FOREIGN  TAXATION.  Income  received by a Fund from sources  within a foreign
country may be subject to  withholding  and other taxes imposed by that country.
Tax conventions  between certain  countries and the U.S. may reduce or eliminate
such taxes.

   The  payment  of  such  taxes  will  reduce  the  amount  of  dividends   and
distributions paid to the Funds' stockholders.  So long as a Fund qualifies as a
regulated investment company,  certain distribution  requirements are satisfied,
and more  than 50% of such  Fund's  assets  at the  close  of the  taxable  year
consists of securities of foreign  corporation,  the fund may elect,  subject to
limitation, to pass through its foreign tax credits to its stockholders.
   
   OTHER  TAXES.  The  foregoing  discussion  is  general  in nature  and is not
intended  to provide  an  exhaustive  presentation  of the tax  consequences  of
investing  in a Fund.  Distributions  may also be subject to  additional  state,
local and foreign taxes,  depending on each shareholder's  particular situation.
Depending upon the nature and extent of a Fund's  contacts with a state or local
jurisdiction, the Fund may be subject to the tax laws of such jurisdiction if it
is regarded  under  applicable  law as doing  business  in, or as having  income
derived  from,  the  jurisdiction.  Persons who may be  "substantial  users" (or
"related  persons"  of  substantial  users) of  facilities  financed  by private
activity bonds should consult their tax adviser before purchasing Municipal Bond
Fund shares. (See "Municipal  Securities," page 10.) Shareholders are advised to
consult their own tax advisers with respect to the particular  tax  consequences
to them of an investment in a Fund.
    
ORGANIZATION
   
   The Articles of  Incorporation of Income and Municipal Bond Funds provide for
the  issuance of shares of common stock in one or more classes or series and the
Articles of Cash Fund provide for the issuance of stock in one or more series.

   Income Fund has authorized the issuance of an indefinite  number of shares of
capital  stock of $1.00 par  value  and  currently  issues  its  shares in seven
series,  Corporate Bond Fund, Limited Maturity Bond Fund, U.S.  Government Fund,
High Yield Fund,  MFR  Emerging  Markets  Total  Return  Fund,  MFR Global Asset
Allocation Fund and MFR Global High Yield Fund (formerly Global  Aggressive Bond
Fund).  The shares of each Series of Income Fund represent a pro rata beneficial
interest in that  Series' net assets and in the  earnings  and profits or losses
derived from the  investment of such assets.  Municipal Bond and Cash Funds have
not issued shares in any additional  series at the present time.  Municipal Bond
and Cash Funds have authorized the issuance of an indefinite number of shares of
capital stock of $0.10 par value.

   Each of Corporate Bond,  Limited Maturity Bond, U.S.  Government,  High Yield
and  Municipal  Bond  Funds  currently   issues  two  classes  of  shares  which
participate  proportionately  based  on  their  relative  net  asset  values  in
dividends and distributions and have equal voting,  liquidation and other rights
except that (i) expenses  related to the distribution of each class of shares or
other  expenses that the Board of Directors may designate as class expenses from
time to time,  are borne  solely by each  class;  (ii) each  class of shares has
exclusive voting rights with respect to any  Distribution  Plan adopted for that
class; (iii) each class has different exchange  privileges;  and (iv) each class
has a different  designation.  When issued and paid for, the shares of Corporate
Bond,  Limited Maturity Bond, U.S.  Government,  High Yield,  Municipal Bond and
Cash  Funds  will be fully paid and  nonassessable  by the Funds.  Shares may be
exchanged as described above under "Exchange  Privilege," but will have no other
preference,  conversion, exchange or preemptive rights. Shares are transferable,
redeemable and assignable and have cumulative voting privileges for the election
of directors.

<PAGE>
   On certain  matters,  such as the  election of  directors,  all shares of the
Series of Income Fund vote  together  with each share having one vote.  On other
matters affecting a particular Series,  such as the investment advisory contract
or the  fundamental  policies,  only shares of that Series are entitled to vote,
and a majority vote of the shares of that Series is required for approval of the
proposal.

   The Funds do not generally hold annual meetings of  stockholders  and will do
so only when required by law.  Stockholders  may remove directors from office by
vote cast in person or by proxy at a  meeting  of  stockholders.  Such a meeting
will be called at the written request of 10% of a Fund's outstanding shares.

CUSTODIAN, TRANSFER AGENT AND DIVIDEND-PAYING AGENT
   
   UMB Bank,  N.A.,  928 Grand Avenue,  Kansas City,  Missouri 64106 acts as the
custodian for the portfolio  securities of Corporate Bond Fund, Limited Maturity
Bond Fund, U.S. Government Fund, High Yield,  Municipal Bond Fund and Cash Fund.
Security Management Company, LLC acts as the Funds' transfer and dividend-paying
agent.
    
INDEPENDENT AUDITORS

   The firm of Ernst & Young  LLP,  One Kansas  City  Place,  1200 Main  Street,
Kansas  City,  Missouri,  has been  selected  by a majority  of the  independent
directors of each Fund to serve as the independent auditors of the Funds, and as
such,  the  firm  will  perform  the  annual  audit  of  each  Fund's  financial
statements.

PERFORMANCE INFORMATION
   
   The  Funds  may,  from  time to  time,  include  performance  information  in
advertisements,  sales  literature  or reports to  stockholders  or  prospective
investors.  Performance information in advertisements or sales literature may be
expressed as yield for each of the Funds, effective yield for Cash Fund, taxable
equivalent  yield for  Municipal  Bond Fund and average  annual total return and
aggregate total return for Municipal Bond and Income Funds.

   For Cash Fund,  the current yield will be based upon the seven  calendar days
ending on the date of calculation ("the base period").  The total net investment
income  earned,  exclusive of realized  capital  gains and losses or  unrealized
appreciation  and  depreciation,  during  the  base  period,  on a  hypothetical
pre-existing  account having a balance of one share will be divided by the value
of the account at the beginning of that period.  The resulting figure ("the base
period  return") will then be  multiplied by 365/7 to obtain the current  yield.
Cash Fund's  current yield for the seven-day  period ended December 31, 1997 was
___%.

   Cash Fund's  effective (or compound)  yield for the same period was ___%. The
effective yield reflects the compounding of the current yield by reinvesting all
dividends and will be computed by compounding the base period return by adding 1
to the base period return, raising the sum to a power equal to 365 divided by 7,
and  subtracting  1 from the  result.  The yield of the Fund may be  obtained by
calling the Fund.
    
   Investors  should recognize that investment in Cash Fund is not guaranteed or
insured by any state, federal or government agency or by any other person.
   
   With respect to Income Fund and Municipal Bond Fund, quotations of yield will
be based on the  investment  income per share earned during a particular  30-day
period,  less  expenses per share  accrued  during the period  ("net  investment
income") and will be computed by dividing net  investment  income by the maximum
offering  price  per  share  on the  last day of the  period,  according  to the
following formula:
    
                                     A-B    ^6
                            YIELD=2((--- + 1)  -1)
                                      CD

where A = dividends and interest earned during the period,  B = expenses accrued
for the period  (net of any  reimbursements),  C = the average  daily  number of
shares  outstanding  during the period that were entitled to receive  dividends,
and D = the maximum offering price per share on the last day of the period.
   
   Municipal Bond Fund's  tax-equivalent yield, like yield, is based on a 30-day
period and is computed by dividing that portion of the Fund's yield (computed as
described  above) which is  tax-exempt by one minus a stated income tax rate and
adding the resulting figure to that portion of the Fund's yield, if any, that is
not tax-exempt.

   For the 30-day  period ended  December  31,  1997,  the yield for the Class A
shares of the following Funds was ___% for Corporate Bond Fund, ___% for Limited
Maturity Bond Fund, ___% for the U.S. Government Fund, ___% for High Yield Fund,
and ___% for Municipal Bond Fund. For the same period, the tax equivalent yield

                                       54
<PAGE>
for the Class A shares of Municipal Bond Fund assuming a 15% income tax rate and
a 28% income tax rate, respectively, was ___% and ___%.

   For the 30-day  period ended  December  31,  1997,  the yield for the Class B
shares of the  following  Funds was ___% for the Corporate  Bond Fund,  ___% for
Limited  Maturity Bond Fund,  ___% for the U.S.  Government  Fund, ___% for High
Yield Fund,  and ___% for  Municipal  Bond Fund.  For the same  period,  the tax
equivalent  yield for the Class B shares of Municipal  Bond Fund  assuming a 15%
income tax rate and a 28% income tax rate, respectively, was ___% and ___%.
    
   There is no  assurance  that a yield  quoted  will  remain in effect  for any
period of time.  Inasmuch as certain estimates must be made in computing average
daily  yield,  actual  yields may vary and will depend upon such  factors as the
type of instruments in the Fund's  portfolio,  the portfolio quality and average
maturity  of such  instruments,  changes in  interest  rates and the actual Fund
expenses.  Yield computations will reflect the expense limitations  described in
this Prospectus under "Investment Manager."

   
   Quotations  of average  annual total return will be expressed in terms of the
average annual compounded rate of return of a hypothetical  investment in Income
Fund or Municipal Bond Fund over periods of 1, 5 and 10 years (up to the life of
the Fund), calculated pursuant to the following formula:
    
                                     ^n
                                P(1+T)  =ERV

(where P = a  hypothetical  initial  payment of $1,000,  T = the average  annual
total return, n = the number of years, and ERV = the ending  redeemable value of
a hypothetical $1,000 payment made at the beginning of the period).  All average
annual total return  figures will reflect the  deduction of the maximum  initial
sales load in the case of  quotations  of  performance  of Class A shares or the
applicable  contingent  deferred  sales  charge  in the  case of  quotations  of
performance  of Class B shares and a  proportional  share of Fund expenses on an
annual basis,  and assume that all dividends and  distributions  are  reinvested
when paid.

   For the 1-, 5- and 10-year  periods  ended  December  31,  1996,  the average
annual  total return for Class A shares of the  Corporate  Bond Fund was -5.69%,
4.96% and 6.74%,  respectively.  For the 1-year period ended  December 31, 1996,
the average  annual total  return for Class B shares of Corporate  Bond Fund was
- -6.29%.  For the period  October 19, 1993 (date of  inception)  to December  31,
1996,  the average  annual total return for Class B shares of the Corporate Bond
Fund was -0.28%.
   
   For the 1-, 5- and 10-year  periods  ended  December  31,  1997,  the average
annual  total  return for Class A shares of the U.S.  Government  Fund was ___%,
___% and ___%, respectively.  For the 1-year period ended December 31, 1997, the
average annual total return for Class B shares of U.S. Government Fund was ___%.
For the period  October 19, 1993 (date of inception)  to December 31, 1997,  the
average annual total return for Class B shares of the U.S.  Government  Fund was
___%.

   For the 1-, 5- and 10-year  periods  ended  December  31,  1997,  the average
annual total return for Class A shares of Municipal Bond Fund was ___%, ___% and
___%,  respectively.  For the 1-year period ended December 31, 1997, the average
annual total return for Class B shares of Municipal  Bond Fund was ___%. For the
period  October 19, 1993 (date of inception)  to December 31, 1997,  the average
annual total return for Class B shares of Municipal Bond Fund was ___%.

   For the 1-year  period  ended  December 31,  1997,  the average  annual total
return for Class A and B shares of Limited Maturity Bond Fund was ___% and ___%,
respectively.  For the period  January 17, 1995 (date of  inception) to December
31,  1997,  the average  annual total return for Class A and B shares of Limited
Maturity Bond Fund was ___% and ___%, respectively.

   For the 1-year  period  ended  December 31,  1997,  the average  annual total
return  for  Class  A and B  shares  of High  Yield  Fund  was  ___%  and  ___%,
respectively.  For the period August 5, 1996 (date of inception) to December 31,
1997,  the average  annual  total  return for Class A and B shares of High Yield
Fund was ___% and ___%, respectively.

   The aggregate  total return for Income and Municipal Bond Funds is calculated
for any specified period of time pursuant to the following formula:
    
                                     ^n
                                P(1+T)  =ERV

(where P = a hypothetical  initial payment of $1,000, T = the total return,  and
ERV = the ending  redeemable value of a hypothetical  $1,000 payment made at the
beginning of the period). All aggregate total return figures will

                                       55
<PAGE>
assume that all dividends and  distributions are reinvested when paid. The Funds
may, from time to time,  include  quotations of total return that do not reflect
deduction of the sales load which,  if reflected,  would reduce the total return
data quoted.
   
   The  aggregate  total return on an  investment  made in Class A shares of the
Corporate Bond Fund, the U.S. Government Fund and Municipal Bond Fund calculated
as described above for the period from December 31, 1987, for the Corporate Bond
Fund, U.S.  Government Fund and Municipal Bond Fund,  through  December 31, 1997
was ___%, ___% and ___%,  respectively.  These figures reflect  deduction of the
maximum initial sales load.

   The  aggregate  total return on an  investment  made in Class B shares of the
Corporate Bond Fund, the U.S. Government Fund and Municipal Bond Fund calculated
as described above for the period October 19, 1993 through December 31, 1997 was
___%,  ___% and ___%,  respectively.  These  figures  reflect  deduction  of the
maximum contingent deferred sales charge.

   The aggregate  total return on an investment  made in Class A and B shares of
the Limited  Maturity Bond Fund for the period January 17, 1995 through December
31, 1997 was ___% and ___%, respectively. These figures reflect deduction of the
maximum  initial  sales load and  deduction of the maximum  contingent  deferred
sales charge.

   The aggregate  total return on an investment  made in Class A and B shares of
the High Yield Fund for the period  August 5, 1996 (date of  inception)  through
December  31,  1997,  was ___% and ___%,  respectively.  These  figures  reflect
deduction  of the  maximum  initial  sales  load and  deduction  of the  maximum
contingent deferred sales charge.
    
   In addition, quotations of aggregate total return will also be calculated for
several consecutive one-year periods expressing the total return as a percentage
increase or decrease in the value of the  investment  for each year  relative to
the ending value for the previous year.

   Quotations of yield,  tax-equivalent  yield,  average annual total return and
aggregate  total  return will  reflect only the  performance  of a  hypothetical
investment  during the particular  time period shown.  Such quotations will vary
based on changes in market conditions and the level of the Fund's expenses,  and
no reported performance figure should be considered an indication of performance
which may be expected in the future.
   
   In connection with  communicating its yield,  tax-equivalent  yield,  average
annual  total  return or  aggregate  total  return  to  current  or  prospective
stockholders,  each Fund also may compare  these figures to the  performance  of
other mutual funds tracked by mutual fund rating  services or to other unmanaged
indexes which may assume  reinvestment of dividends but generally do not reflect
deductions  for  administrative  and  management  costs.  Each Fund will include
performance  data  for  both  Class A and  Class  B  shares  of the  Fund in any
advertisement or report including performance data of the Fund. Such mutual fund
rating services include the following: Lipper Analytical Services;  Morningstar,
Inc.; Investment Company Data; Schabacker  Investment  Management;  Wiesenberger
Investment  Companies Service;  Computer  Directions Advisory (CDA); and Johnson
Charts.
    
RETIREMENT PLANS

   Corporate Bond, Limited Maturity Bond, U.S.  Government,  High Yield and Cash
Funds  offer   tax-qualified   retirement  plans  for  individuals   (Individual
Retirement Accounts,  known as IRAs), several prototype retirement plans for the
self-employed (Keogh plans),  pension and profit-sharing plans for corporations,
and  custodial  account  plans  for  employees  of  public  school  systems  and
organizations  meeting the  requirements  of Section  501(c)(3)  of the Internal
Revenue Code.  Actual  documents and detailed  materials about the plans will be
provided upon request to the Distributor.

   Purchases of Corporate Bond,  Limited  Maturity Bond, U.S.  Government,  High
Yield  and Cash Fund  shares  under  any of these  plans are made at the  public
offering  price  next  determined  after   contributions  are  received  by  the
Distributor.  Shares owned under any of the plans have full dividend, voting and
redemption  privileges.  Depending  upon  the  terms  of  the  particular  plan,
retirement benefits may be paid in a lump sum or in installment  payments over a
specified period. There are possible penalties for premature  distributions from
such plans.

   Security  Management  Company,  LLC is available to act as custodian  for the
plans on a fee basis. For IRAs,  SIMPLE IRAs,  Section 403(b)  Retirement Plans,
and Simplified  Employee Pension Plans (SEPPs),  service fees for such custodial
services currently are: (1) $10 for annual  maintenance of the account,  and (2)
benefit distribution fee of $5 per distribution. Service fees for other types of
plans will vary.  These fees will be  deducted  from the plan  assets.  Optional
supplemental services are available from Security Benefit Life Insurance Company
for additional charges.

                                       56
<PAGE>
   Retirement  investment programs involve commitments covering future years. It
is important  that the  investment  objective and  structure of Corporate  Bond,
Limited Maturity Bond, U.S. Government,  High Yield and Cash Funds be considered
by the investors for such plans.  Investments in insurance and annuity contracts
also may be purchased in addition to shares of the Funds.
   
   A brief  description  of the  available  tax-qualified  retirement  plans  is
provided below.  However,  the tax rules applicable to such qualified plans vary
according to the type of plan and the terms and  conditions  of the plan itself.
Therefore, no attempt is made to provide more than general information about the
various  types of qualified  plans.  Because  Municipal  Bond Fund's  investment
objective  is to obtain a high level of  interest  income  exempt  from  federal
taxes,  Municipal  Bond Fund is not an  appropriate  investment  for  retirement
plans.
    
   Investors  are urged to consult  their own  attorneys  or tax  advisers  when
considering the establishment and maintenance of any such plans.

INDIVIDUAL RETIREMENT ACCOUNTS (IRAS)

   Individual  Retirement Account Custodial  Agreements are available to provide
investment in shares of Corporate Bond, Limited Maturity Bond, U.S.  Government,
High Yield or Cash Fund, or in other Funds in the Security  Group. An individual
may initiate an IRA through the Distributor by executing the custodial agreement
and making a minimum  initial  investment  of at least $100. A $10 annual fee is
charged for maintaining the account.

   An individual may make a contribution to a traditional IRA each year of up to
the lesser of $2,000 or 100% of earned  income  under  current tax law. The IRAs
described in this paragraph are called  "traditional  IRAs" to distinguish  them
from the new "Roth IRAs" which become available in 1998. Roth IRAs are described
below.  Spousal IRAs allow an individual  and his or her spouse to contribute up
to $2,000 to their  respective  IRAs so long as a joint tax  return is filed and
joint income is $4,000 or more. The maximum amount the higher compensated spouse
may  contribute  for the year is the  lesser of $2,000 or 100% of that  spouse's
compensation.  The maximum the lower  compensated  spouse may  contribute is the
lesser of (i) $2,000 or (ii) 100% of that spouse's  compensation plus the amount
by which the higher  compensated  spouse's  compensation  exceeds the amount the
higher compensated spouse contributes to his or her IRA.

   Deductions for IRA contributions are limited for taxpayers who are covered by
an employer-sponsored  retirement plan. However,  these limitations do not apply
to a single  taxpayer with  adjusted  gross income of $25,000 or less or married
taxpayers  with  adjusted  gross income of $40,000 or less (if they file a joint
tax return). Taxpayers with adjusted gross income less than $10,000 in excess of
these amounts may deduct a portion of their IRA contributions. The nondeductible
portion is calculated by reference to the amount of the taxpayer's  income above
$25,000 (single) or $40,000 (married) as a percentage of $10,000.

   Contributions must be made in cash no later than April 15 following the close
of the tax year. No annual  contribution  is permitted for the year in which the
investor reaches age 70 1/2 or any year thereafter.

   In addition to annual contributions,  total distributions and certain partial
distributions from certain  employer-sponsored  retirement plans may be eligible
to be reinvested  into a traditional  IRA if the  reinvestment is made within 60
days of receipt of the distribution by the taxpayer. Such rollover contributions
are not subject to the limitations on annual IRA contributions described above.

ROTH IRAS

   Section 408A of the code  permits  eligible  individuals  to establish a Roth
IRA, a new type of IRA which becomes available in 1998.  Contributions to a Roth
IRAs are not deductible,  but withdrawals that meet certain requirements are not
subject to federal  income  tax.  In  general,  Roth IRAs are subject to certain
required distribution requirements.  Unlike a traditional IRA, Roth IRAs are not
subject to minimum  required  distribution  rules  during the owner's life time.
Generally,  however,  the amount in a remaining  Roth IRA must be distributed by
the end of the fifth year after the death of the owner.

   Beginning in 1998 the owner of a traditional  IRA may convert the traditional
IRA into a Roth IRA under certain circumstances. The conversion of a traditional
IRA to a Roth IRA will subject the amount of the  converted  traditional  IRA to
federal income tax. If a traditional IRA is converted to a Roth IRA, the taxable
amount in the owner's  traditional  IRA will be  considered  taxable  income for
federal  income tax  purposes  for the year of the  conversion.  Generally,  all
amounts  in  a  traditional  IRA  are  taxable  except  for  the  owner's  prior
non-deductible contributions to the traditional IRA.

<PAGE>
SIMPLE IRAS

   The Small Business Job Protection Act of 1996 created a new retirement  plan,
the  Savings  Incentive  Match Plan for  Employees  of Small  Employers  (SIMPLE
Plans).  SIMPLE Plan  participants  must  establish a SIMPLE IRA into which plan
contributions will be deposited.

   The Investment  Manager makes available SIMPLE IRAs to provide  investment in
shares of the Funds. Contributions to a SIMPLE IRA may be either salary deferral
contributions or employer contributions.  Contributions must be made in cash and
cannot exceed the maximum amount  allowed under the Internal  Revenue Code. On a
pre-tax basis,  up to $6,000 of compensation  (through salary  deferrals) may be
contributed to a SIMPLE IRA. In addition,  employers are required to make either
(1) a dollar-for-dollar  matching contribution or (2) a nonelective contribution
to each participant's account each year. In general, matching contributions must
equal up to 3% of compensation,  but under certain circumstances,  employers may
make lower matching  contributions.  Instead of the match,  employers may make a
nonelective contribution equal to 2% of compensation  (compensation for purposes
of any nonelective contribution is limited to $160,000, as indexed).

   Distributions  from a  SIMPLE  IRA are (1)  taxed  as  ordinary  income;  (2)
includable in gross income; and (3) subject to applicable state tax laws.

   Distributions  prior to age 59 1/2 may be subject to a 10%  penalty tax which
increases to 25% for distributions made before a participant has participated in
the  SIMPLE  Plan for at least two years.  An annual  fee of $10 is charged  for
maintaining the SIMPLE IRA.

PENSION AND PROFIT-SHARING PLANS

   Prototype  corporate  pension or  profit-sharing  prototype plans meeting the
requirements of Internal Revenue Code Section 401(a) are available.  Information
concerning these plans may be obtained from Security Distributors, Inc.

403(B) RETIREMENT PLANS

   Employees of public school systems and tax-exempt  organizations  meeting the
requirements of Internal Revenue Code Section  501(c)(3) may purchase  custodial
account plans funded by their employers with shares of Corporate  Bond,  Limited
Maturity Bond,  U.S.  Government,  High Yield or Cash Fund or other Funds in the
Security Group in accordance with Code Section 403(b).  Section 403(b) plans are
subject to  numerous  restrictions  on the amount that may be  contributed,  the
persons who are eligible to participate and on the time when  distributions  may
commence.

SIMPLIFIED EMPLOYEE PENSION PLANS (SEPPS)

   A  prototype  SEPP  is  available  for  corporations,  partnerships  or  sole
proprietors  desiring  to adopt  such a plan  for  purchases  of IRAs for  their
employees.  Employers  establishing a SEPP may contribute a maximum of $30,000 a
year to an IRA for each  employee.  This  maximum  is  subject  to a  number  of
limitations.

FINANCIAL STATEMENTS

   The audited  financial  statements  of the Funds,  which are contained in the
Funds'  Annual  Report  dated  December  31, 1996,  are  incorporated  herein by
reference.  Copies of the Annual Report are provided to every person  requesting
the Statement of Additional Information.

TAX-EXEMPT VS. TAXABLE INCOME

   The following table shows the approximate taxable yields for individuals that
are  equivalent to tax-exempt  yields using the 1997 tax rates  contained in the
Internal  Revenue  Code as modified by the Tax Reform Act of 1986.  Beginning in
1989,  federal income  brackets will be indexed each year to reflect  changes in
the Consumer Price Index.  The table  illustrates what you would have to earn on
taxable  investments  to  equal a given  tax-exempt  yield  in your  income  tax
bracket. Locate your income (after deductions and exemptions),  then locate your
tax bracket based on joint or single tax filing.  Read across to the  equivalent
taxable  yield  you would  need to match a given  tax-free  yield.  There is, of
course,  no assurance  that an investment in Tax-Exempt  Fund will result in the
realization of any particular return.

CLASS A SHARES OF CORPORATE BOND, LIMITED MATURITY BOND, U.S.  GOVERNMENT,  HIGH
YIELD AND MUNICIPAL BOND FUNDS
    
REDUCED SALES CHARGES
   
   Initial  sales   charges  may  be  reduced  or  eliminated   for  persons  or
organizations  purchasing  Class A shares of Corporate  Bond,  Limited  Maturity
Bond,  U.S.  Government,  High  Yield  and  Municipal  Bond  Funds  alone  or in
combination with Class A shares of other Security Funds.
    
   For  purposes of  qualifying  for reduced  sales  charges on  purchases  made
pursuant to Rights of  Accumulation,  a  Statement  of  Intention  or Letters of
Intent, the term "Purchaser" includes the following persons: an individual;  his
or her spouse and children  under the age 21; a trustee or other  fiduciary of a
single trust estate or single fiduciary  account  established for their benefit;
an organization  exempt from federal income tax under Section  501(c)(3) or (13)
of the Internal  Revenue Code; or a pension,  profit-sharing  or other  employee
benefit plan whether or not qualified under Section 401 of the Internal  Revenue
Code.

RIGHTS OF ACCUMULATION
   
   To reduce sales charges on purchases of Corporate Bond Fund, Limited Maturity
Bond Fund, U.S.  Government Fund, High Yield or Municipal Bond Fund, a Purchaser
may combine all previous purchases with a contemplated current purchase of Class
A shares of a Fund for the purpose of determining the sales charge applicable to
the current purchase.  For example,  an investor who already owns Class A shares
of a Fund either  worth  $30,000 at the  applicable  current  offering  price or
purchased  for $30,000 and who invests an additional  $25,000,  is entitled to a
reduced sales charge of 3.75% on the latter  purchase.  The Distributor  must be
notified when a sale takes place which would  qualify for the reduced  charge on
the basis of  previous  purchases  subject  to  confirmation  of the  investor's
holdings  through  the  Fund's  records.  Rights of  accumulation  apply also to
purchases  representing  a combination  of the Class A shares of Corporate  Bond
Fund,  Limited Maturity Bond Fund, U.S.  Government Fund, High Yield,  Municipal
Bond Fund,  Security Growth and Income,  Security Ultra Fund, or Security Equity
Fund in those states where shares of the Funds being purchased are qualified for
sale.
    
STATEMENT OF INTENTION
   
   A Purchaser in Corporate Bond, Limited Maturity Bond, U.S.  Government,  High
Yield or Municipal  Bond Funds may sign a Statement of  Intention,  which may be
signed within 90 days after the first purchase to be included thereunder, in the
form  provided by the  Distributor  covering  purchases of Corporate  Bond Fund,
Limited  Maturity Bond Fund, U.S.  Government  Fund, High Yield,  Municipal Bond
Fund,  Security Equity Fund,  Security Growth and Income Fund, or Security Ultra
Fund to be made within a period of 13 months (or a 36-month period for purchases
of $1 million or more) and thereby  become  eligible  for the reduced  front-end
sales charge applicable to the actual amount purchased under the Statement. Five
percent of the amount  specified in the  Statement of Intention  will be held in
escrow shares until the Statement is completed or terminated. The shares so held
may be redeemed by the Fund if the investor is required to pay additional  sales
charge which may be due if the amount of purchases  made by the investor  during
the period the  Statement is  effective is less than the total  specified in the
Statement of Intention.
    
   A Statement of Intention  may be revised  during the 13-month  period (or, if
applicable,   36-month   period).   Additional  Class  A  shares  received  from
reinvestment  of income  dividends and capital gains  distributions  (if any are
realized)  are  included in the total  amount used to  determine  reduced  sales
charges. The Statement is not a binding obligation upon the investor to purchase
or any Fund to sell the full indicated amount. An investor  considering  signing
such an agreement should read the Statement of Intention carefully.  A Statement
of Intention form may be obtained from the Investment Manager.

REINSTATEMENT PRIVILEGE
   
   Stockholders who redeem their Class A shares of Corporate Bond Fund,  Limited
Maturity Bond Fund, U.S. Government Fund, High Yield Fund or Municipal Bond Fund
have a one-time  privilege (1) to reinstate their accounts by purchasing  shares
of the Fund  without a sales  charge up to the dollar  amount of the  redemption
proceeds,  or (2) to the extent the redeemed shares would have been eligible for
the  exchange  privilege,  to  purchase  Class A shares of another of the Funds,
Security Equity Fund, Security Ultra Fund, or Security Growth and Income Fund up
to the dollar amount of the  redemption  proceeds at a sales charge equal to the
additional  sales  charge,  if any,  which  would have been  applicable  had the
redeemed  shares been  exchanged  pursuant to the  exchange  privilege.  Written
notice and a check in the amount of the reinvestment from eligible  stockholders
wishing to exercise this  reinstatement  privilege  must be received by the Fund
within  thirty days after the  redemption  request was  received (or such longer
period  as may be  permitted  by rules  and  regulations  promulgated  under the
Investment  Company  Act of 1940).  The net asset  value used in  computing  the
amount of shares to be issued upon  reinstatement  or  exchange  will be the net
asset value on the day that notice of the exercise of the privilege is received.
Stockholders  making use of the  reinstatement  privilege  should  note that any
gains  realized  upon the  redemption  will be  taxable  while any losses may be
deferred under the "wash sale" provision of the Internal Revenue Code.

SECURITY FUNDS

FEBRUARY 15, 1997

[PHOTO OF JOHN CLELAND]
JOHN CLELAND

Dear Shareholder:

     1996 was not a particularly good year for fixed income investors.  Interest
rates fluctuated dramatically throughout the year, with the thirty-year Treasury
bond  beginning the year at 5.94% and ending it 70 basis points higher at 6.64%.
Only in the global fixed income markets did we see attractive returns.  The U.S.
markets  continued  to be ruled by  investors'  fears about the  reemergence  of
inflationary  pressures  and  expectations  as to the  future  rate of  economic
growth.  Although growth was moderate and inflation remained well under control,
the fear, rather than the fact, dominated bond market movements.

1997 OUTLOOK FOR FIXED INCOME

     We believe the fixed income outlook for 1997 is much better. We expect that
last  year's  moderate  inflation  levels  will  remain in place for some  time.
Consumer spending,  a primary force behind rising inflation,  will be restrained
by the high  household  debt  levels  now in place.  Although  many  people  are
experiencing the "wealth effect" of strong stock markets, these individuals tend
to be savers rather than spenders and are content to watch their earnings grow.

BALANCED BUDGET PROSPECTS IMPROVING

     A strong positive for bond markets is the likelihood that a balanced budget
proposal will become  reality in 1997.  Sentiment is strong on both sides of the
congressional  aisle, and since 1997 is not an election year, the possibility of
bipartisan  agreement is greater than usual.  Should a balanced  budget  package
become a reality,  the promise of reduced Federal  spending lowers the potential
for inflation and pleases fixed income investors.

DECLINING GLOBAL INTEREST RATES 

     An  additional  plus for fixed income is the outlook for  declining  global
interest rates as inflation drops in many countries around the world, and as the
European  nations work to meet  criteria  for entry into the  European  Monetary
Union.  Many of these nations have reduced their debt levels,  allowing interest
rates to come down in the process.  They will  continue  along this track as the
January,  1998 date for selection of participants in the EMU approaches.

     In our opinion,  all of these factors  combined make an excellent  backdrop
for favorable fixed income  performance in the year ahead. As always,  we invite
your comments and questions.

Sincerely,


John Cleland
President, Security Funds

MANAGERS' COMMENTARY
- --------------------------------------------------------------------------------
SECURITY FUNDS

FEBRUARY 15, 1997

SECURITY INCOME FUND
CORPORATE BOND SERIES

At the  beginning  of 1996 the  Corporate  Bond  Series'  average  maturity  and
duration were long relative to our benchmark index,  anticipating a continuation
of the previous  year's low inflation,  moderate  economic  growth and declining
interest  rates.  At that time the yield on the  thirty-year  Treasury  bond was
5.94%.  The first major economic  release for the year,  the January  employment
figures,  shocked bond investors when it showed much higher levels of employment
than expected. This set the tone for a year of uncertainty about economic growth
and inflation. The long Treasury bond rose to a high of almost 7.20% in June and
again in July.  It  closed  the year  down from  that  level,  but at 6.64%,  it
remained well above its opening level for the year.

EARLY STEPS TO READJUST THE PORTFOLIO

In February we began  shortening  the maturity  structure of the portfolio to be
more in line with that of the benchmark  index and with our peers.  In addition,
we started purchasing issues in three  newly-approved  asset classes,  including
U.S.  dollar-denominated  foreign bonds ("Yankee"  bonds),  high yield bonds and
mortgage-backed securities. These proved to be wise moves, as the high yield and
mortgage sectors  outperformed  corporate bonds throughout the year. For most of
1996  mortgage-backed  securities  made up about 15% of the  portfolio  and high
yield issues approximately 17%.

The  exposure  to Yankee  bonds also did well,  with about 12% of the  portfolio
invested in such issues.  The largest of these holdings is Banco Santander,  one
of the  largest  banks in Spain  with  assets in excess  of $132  billion  (U.S.
dollars).  Others in the Yankee bond sector  include  Abbey  National  Bank PLC,
Malayan  Bank of New York,  Panamerican  Beverage  Company  and  Banco  Centrale
Hispanoamericano.(1)

HIGH YIELD HOLDINGS IN THE SECOND HALF OF THE YEAR

After we  realigned  the  portfolio's  maturity  structure  early  in the  year,
performance was strong in the second and third quarters as we outperformed  both
our  benchmark  index and our peer  group.  The fourth  quarter  was a different
story. Performance was negatively impacted by our investment in Marvel Holdings,
Inc. bonds,  which declined  substantially in value after the company  announced
poor earnings warning investors of liquidity problems. Another high yield issue,
Home Holdings, also lost considerable value after the company became involved in
litigation surrounding the lease on its Maiden Lane headquarters in New York.

Given the negative contribution of these two high yield bond positions,  we have
refined our strategy for using high yield issues in the portfolio.

MANAGERS' COMMENTARY
- --------------------------------------------------------------------------------
SECURITY FUNDS

FEBRUARY 15, 1997

In order to reduce the impact of negative  performance by any one issue,  we are
increasing the number of individual  investments in the sector while keeping our
overall sector allocation unchanged.  This has the effect of limiting the fund's
exposure to any one position to around 1% of portfolio assets.

THOUGHTS ABOUT 1997

We believe  the  outlook  for bonds in 1997 is better than at this time in 1996.
Economic growth should continue at a slow but steady pace,  restrained  somewhat
by slow consumer  spending as  individuals  concentrate  on reducing  their debt
burdens.  The Federal  Reserve Open Market  Committee will continue its vigilant
stance against inflation.  Aided by falling global inflation and interest rates,
we  believe  the  U.S.  bond  markets  should  be able  to  post a  near-average
performance year.

MANAGERS' COMMENTARY
- --------------------------------------------------------------------------------
SECURITY FUNDS

FEBRUARY 15, 1997

U.S. GOVERNMENT SERIES

The U.S.  Government  securities  markets  had  mixed  results  in 1996,  as the
interest  rate on the long Treasury bond rose from 5.94% at the beginning of the
year to 6.64% at its close. Its total return for the year was -2.3%,  while over
the same period the  two-year  Treasury  note gained 5.2%.  The U.S.  Government
Series,  which contains  issues of varying  maturities,  fell in between the two
with a total return for the year of 1.26%.(1)

MORTGAGE-BACKED SECURITIES REPRESENTATION

About 30% of the portfolio was invested in mortgage-backed securities (primarily
GNMA's)  most of the year.  These issues  perform  well in bear markets  because
generally as interest rates rise fewer people  refinance  their home  mortgages.
This reduces prepayments on mortgage-backed securities and helps stabilize their
prices.  The issues we hold have coupon rates ranging from 7.5% to 8.5%,  adding
an attractive income stream to the portfolio's return.

REALIGNMENT OF MATURITY STRUCTURE

In February and March the yield on the thirty-year Treasury bond rose from 6.02%
to 6.64%,  its largest price  decline of the year.  The U.S.  Government  Series
contained a number of  long-maturity  issues at the beginning of February  which
hurt  portfolio  performance  at that time.  Part of these  issues  were sold in
March,  which helped the balance of the year, but of course could not repair the
damage done before the sales.

PLANS FOR 1997

We believe that  interest  rates in the first half of 1997 have a good chance of
declining as economic  activity slows somewhat and inflation  remains well under
control.  We may  increase  the  percentage  of the  portfolio  holdings in GNMA
mortgage-backed  security issues,  as we feel that the greatest portion of total
return in 1997 will come from the income stream provided by the securities.  The
duration of the  portfolio  will  probably  remain close to its current level of
about five  years.  Although  the year ahead may not be an  outstanding  one for
fixed  income  instruments,  we believe  it will be at least an average  one for
total returns.

                             $10,000 OVER TEN YEARS

This chart  assumes a $10,000  investment  in Class A shares of U.S.  Government
Series on December 31, 1986, and reflects  deduction of the 4.75% sales load. On
December 31, 1996,  the value of your  investment  in the Series' Class A shares
(with dividends reinvested) would have grown to $19,846. By comparison, the same
$10,000  investment  would have grown to $21,846 based on the performance of the
Lehman Brothers Government Bond Index.

The performance illustrated above is based on the performance of Class A shares.
The  performance of Class B shares will be greater or less than the  performance
shown for Class A shares as a result of the different  loads and fees associated
with an investment in Class B shares.

The performance  data illustrated  above reflects past performance  which is not
predictive of future results.

The Lehman Brothers  Government Bond Index is made up of all public  obligations
of the U.S. Treasury,  excluding flower bonds and  foreign-targeted  issues, all
publicly issued debt of U.S. Government agencies and quasi-federal corporations,
and corporate debt guaranteed by the U.S. Government. Investments cannot be made
directly in an index.

MANAGERS' COMMENTARY
- --------------------------------------------------------------------------------
SECURITY FUNDS

FEBRUARY 15, 1997

LIMITED MATURITY BOND SERIES

In its second year of existence  the Limited  Maturity Bond Series is doing what
it was designed to do--provide  lower  volatility and downside  protection  than
longer-maturity  funds in periods of rising  interest  rates. In a year in which
the thirty-year Treasury bond had a total return of -2.3%, the portfolio's total
return of 2.09% looked quite good.(1)

USE OF MORTGAGE-BACKED SECURITIES IN THE PORTFOLIO

One way to reduce  volatility  without  sacrificing the income stream is through
the use of certain  mortgage-backed  securities,  which make up just over 20% of
the portfolio.  Our strategy in this portion of the Limited  Maturity  portfolio
has been to combine  seasoned premium  mortgage-backed  issues having coupons in
the 8% to 9% range with other  lower-coupon  discounted issues which we consider
to be  undervalued.  The  combination of these two provides both defensive price
movement  characteristics  in periods of modest interest rate  fluctuations  and
yields generally 1/2 to 1% higher than Treasury bonds.

CORPORATE HOLDINGS IN THE FUND

In the  investment  grade  corporate  bond portion of the portfolio we are using
fewer "Yankee" bonds  (dollar-denominated  issues of foreign  companies) than in
the other fixed income funds, and buying more domestic industrial issues.  These
bonds,  issued by companies  such as Aluminum  Company of America and Ford Motor
Company, have historically shown less price volatility than bonds in the finance
and utility sectors of the market.

The high yield portion,  currently about 18% of the fund, will generally provide
a substantial  income stream to enhance the total return.  In the fourth quarter
of 1996, however,  performance was hurt by our Marvel Holdings, Inc. bonds which
declined  substantially  in value  after the company  announced  much lower than
expected earnings,  coupled with liquidity problems.  We sold the bonds in early
December and the company subsequently filed for bankruptcy  protection.  Another
high yield issue, Home Holdings,  also lost considerable  value and hurt overall
performance.  The significant  performance  drag created by these two issues has
led us to take steps to lessen the impact of any future events in the high yield
sector by limiting  each holding to 1% or less of the total  portfolio.  We will
continue to  concentrate  on the  upper-tier  rating  brackets of the high yield
market.

OUTLOOK FOR 1997

We believe that in 1997  interest  rates will  continue to  fluctuate,  although
probably not as widely as in 1996.  We plan to continue the  volatility-reducing
strategies  outlined above,  possibly selling some of the longer maturity issues
in the  portfolio as well. If 1997 turns out to have total returns in an average
range of 5% to 7%, the strong income component will contribute a greater part of
the return than will price appreciation.

MANAGERS' COMMENTARY
- --------------------------------------------------------------------------------
SECURITY FUNDS

FEBRUARY 15, 1997

GLOBAL AGGRESSIVE BOND SERIES

1996 was a very rewarding  year for our  shareholders,  particularly  during the
second half.  While the first six months  provided a total return of 2.58%,  the
last six months' strong performance brought the total return of the fund for the
year up to 11.56%.(1)  This compares  favorably with the Lehman  Brothers Global
Bond Index  return of 5.37% for the year,  a 0.2%  return  for a  ten-year  U.S.
Treasury note, and 10.4% average for the Lipper peer group.

INTERNATIONAL STRENGTH IN THE SECOND HALF

The second half of 1996 saw an acceleration of the trends which began earlier in
the year.  Yields in peripheral  European  countries such as Spain,  Italy,  and
Portugal,  which had  fallen  approximately  1% in the  first  half of the year,
declined a further 2% in the second half.  Restrictive  fiscal policies by these
governments  brought  about by their  desire not to be left out of the  European
Monetary  Union  process  combined with rapidly  declining  inflation to produce
these dramatic  declines in yields.  While there is still room for this trend to
continue,  we believe  the  majority of this  convergence  of yields with "core"
Europe is coming to an end.

Emerging  market debt also  continued its good  performance.  With the strongest
concentration  of  economic  growth in the  world,  the  credit  quality of many
emerging  market  countries and companies is increasing  and should  continue on
that path in 1997.

DOLLAR BLOC PERFORMANCE

One of the  differences in the second half of 1996 versus the first half is that
the dollar bloc which  includes  Australia,  Canada,  New Zealand and the United
States also performed very well.  Interest  rates,  which had increased in these
countries in the first half on the back of a poor U.S.  market,  reversed  their
upward trend.  While longer term rates in the U.S. managed to decline  slightly,
yields in the rest of the dollar bloc fell substantially,  on the order of 1% to
1.5%. Recognition of the continued trend of low inflation in these countries was
the main contributing factor to the decline in yields.

OUTLOOK FOR 1997

Looking ahead to 1997, we believe that the most  rewarding  investments  will be
those that seek out improving credit quality situations, both on the country and
company  level.  In  particular,  the return of strong  growth to Latin  America
should provide fertile ground for many of these  opportunities.  We look forward
to the challenges of the new year.

HIGH YIELD SERIES

The High Yield Series began operations  August 5, 1996 with a primary  objective
of  seeking  high  current   income  with  a  secondary   objective  of  capital
appreciation.  Although  the  Series  may  invest in debt  issues in any  rating
category below  investment  grade, our current focus is on issues rated BB or B,
in the upper  tier of the  noninvestment  grade  range.  Given the length of the
current economic  expansion in the United States,  the possibility is increasing
that we may  experience a slowdown in the months to come. If this  happens,  the
higher-rated  high  yield  issues  are likely to  outperform  their  lower-rated
counterparts   because  of  their  stronger  balance   sheets.

LARGEST INDUSTRY REPRESENTATIONS

The largest industry  concentration in the portfolio is in consumer goods,  both
cyclical  and  noncyclical.  Many  of  the  issuers  will  be  familiar  to  our
shareholders,  including  cyclical  ones such as sheet  and  towel  manufacturer
Westpoint-Stevens,  Inc., cable providers Rogers  Cablesystems  Ltd. and Century
Communications, and gaming company Showboat, Inc. Others may be less familiar by
name, but their  services are  well-known:  one example is K-III  Communications
Corporation,  publishers  of  Weekly  Reader,  Seventeen  magazine,  and  Funk &
Wagnalls  dictionaries,  among other  products.

Among the consumer  noncyclical  companies in the portfolio is AMF Group,  Inc.,
provider of bowling  centers  and  equipment.  AMF is  currently  designing  new
bowling center  packages for  construction  in emerging  market  countries where
industry penetration is low or nonexistent.  Other consumer noncyclicals include
Carrols  Corporation,  the largest operator of Burger King franchises,  and Cott
Corporation, which manufactures private-label soft drinks.

OTHER SECTORS IN THE PORTFOLIO

The  portfolio at this time is  underweighted  in basic  industries,  especially
those whose  assets are subject to commodity  pricings,  such as steel and paper
companies.  The energy sector,  where exploration and production  companies have
excellent  cash flows,  is  overweighted  in the portfolio  versus the benchmark
Lehman Brothers High Yield Index, as are nonbank financial services companies.

The  High  Yield  Series  has  gained  a  respectable  5.20%  since  its  August
inception.(1)  The  performance was held back somewhat by our position in Marvel
Holdings,  Inc. bonds,  which declined  substantially  in value when the company
announced that they were experiencing  liquidity  problems.  The bonds were sold
out of the portfolio in November, and have dropped considerably further in price
since then.

THE HIGH YIELD OUTLOOK IN 1997

As discussed  earlier,  our portfolio is higher in quality than many in our high
yield  peer  group.  A  number  of the  peer  funds  use  common  stock in their
portfolios, as well. In a bull market like we experienced in 1995 and 1996 those
portfolios may perform better,  but with the likelihood of an economic  slowdown
in the  not-too-distant  future,  higher-rated  issues  should  hold their value
better.  We believe  that the high yield bond  markets are likely to have a good
year in 1997  relative to other fixed income asset  classes,  drawing a sizeable
part of their total return from their higher coupons.

Tom Swank
Portfolio Manager

(1) Performance figures are based on Class A shares and do not reflect deduction
of the sales charge.

Investors should remember that while high yield bonds provide potentially higher
yields than many other types of bonds, they also present greater credit risk.

MANAGERS' COMMENTARY

SECURITY FUNDS

FEBRUARY 15, 1997

SECURITY TAX-EXEMPT FUND

Despite a year in which  presidential  candidates  spoke frequently of tax cuts,
the  tax-exempt  market  actually  fared better than its Treasury and  corporate
counterparts.  Municipal  bond  investors may be realizing that in a time when a
balanced federal budget is receiving  serious  consideration,  the likelihood of
relevant tax cuts is diminished.

MATURITY RESTRUCTURING EARLY IN 1996

At the  beginning  of 1996 the  average  duration  of the bonds in the  Security
Tax-Exempt  Fund was quite long, at about 9.5 years.  This hurt  performance  in
January  and  February  as  interest  rates  rose  rapidly.   We  shortened  the
portfolio's average maturity and duration over that time, and for the balance of
the year, it performed well in line with the benchmark index.

In order to lower the volatility of the portfolio, we have reduced the number of
issues that are subject to call risk.  Callable bonds are ones which the issuers
can buy back when interest rates decline, replacing them with lower-coupon bonds
and lowering their interest expense.  These issues can fluctuate widely in price
as  general  market  levels  move  above or below  the call  price,  alternately
reducing or increasing the likelihood that they will be called.  Because of this
risk,  callable bonds can often be purchased at a higher yield than  noncallable
issues.

CREDIT RATINGS IN THE PORTFOLIO

To replace this higher yield,  we have opted to take a slightly  greater  credit
risk, purchasing some issues rated in the low-A to high BBB range. Some of these
include  bonds issued by colleges and  universities,  such as dormitory  revenue
bonds.  We plan to buy smaller  block sizes when we purchase  these  lower-rated
issues, to minimize the impact should any issue experience  credit problems.  We
plan to keep the average  credit  rating of the portfolio  slightly  higher than
that of our peer funds. We believe that as Congress moves to balance the federal
budget, many costs will be pushed down to the state and local government levels,
straining  those  municipalities'  budgets.  A higher average credit rating will
afford some degree of protection  against  unforseen  problems.

CONGRESS AND TAX CUTS

As mentioned earlier,  the likelihood of significant tax cuts for individuals in
1997 has been reduced by the perception  that Congress is intent on presenting a
proposal that will balance the budget in the next five years.  It will be easier
in a  nonelection  year to take  politically  unpopular  steps  such as  cutting
entitlement      programs      without      granting     an      offsetting--and
electorate-pleasing--favor  such as reduced  taxes.  A climate in which tax rate
uncertainty  is  diminished  is  one  which  is  favorable  for  performance  of
tax-exempt bonds.

MANAGERS' COMMENTARY

SECURITY FUNDS

FEBRUARY 15, 1997

SECURITY CASH FUND

Money  market  funds in 1996 became  attractive  alternatives  for  fixed-income
investors,  outperforming  many sectors of the bond market.  Security  Cash Fund
returned  4.63% over the year,  approximating  its Lipper peer group  average of
4.80%.

AVERAGE MATURITY TARGET RANGE

One of our objectives  throughout  the year was to keep the average  maturity of
the  portfolio  holdings  within  ten  days  of  that  published  weekly  in the
IBC/Donoghue  Money Fund  Report.  We avoid the  practice of skewing the average
maturity strongly, either shorter or longer than the benchmark average, in order
to try to outguess the Federal  Reserve Bank and their interest rate  movements.
We believe that a more conservative  approach is appropriate in our money market
funds.

SECTOR REPRESENTATION IN THE PORTFOLIO

We have been adding blocks of Small Business  Administration mortgage pools with
interest rates which reset monthly or quarterly  based on the prime rate.  These
AAA-rated issues provide better yields than commercial  paper, and they are U.S.
Government securities, so there is no additional credit risk in buying them. The
greatest risk with these  instruments is that the mortgages will be prepaid at a
faster-than-anticipated  rate.  For this  reason we  choose  to only buy  issues
priced  at par,  so that no  premium  will  be lost in the  event  of  escalated
prepayments.  Our SBA holdings now make up about 13% of the  portfolio.  

We have also increased our holdings of government  agency issues such as Federal
Farm  Credit  Banks,  Federal  Home Loan  Banks and  Federal  National  Mortgage
Association  securities.  These  issues,  with  maturities  of one year or less,
provide  diversification  from the larger  position in  commercial  paper in the
portfolio.  The IBC/Donoghue  average portfolio  position in commercial paper is
about 60%; we have  reduced  ours from almost 80% to the current 60% in order to
be more in line with that average.

LOOKING AHEAD TO 1997

In 1996 we  established  an overnight  funds  account with the Federal Home Loan
Bank in order to maximize  our earnings on cash  balances.  We continue to study
various  investment  alternatives  for the portfolio  assets in order to provide
competitive interest rates in the fund.

We expect interest rates on short term fixed income investments to stay within a
narrow band in 1997. When inflation has been modest,  as it has for the last two
years,  hints of escalating  economic  growth cause greater  fluctuations in the
longer  maturities  of the bond markets  than in the short ones.  We continue to
strive to provide a high  quality  portfolio  with a  competitive  yield for our
shareholders.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
DECEMBER 31, 1996


1. SIGNIFICANT ACCOUNTING POLICIES

     Security Income Fund,  Security Tax-Exempt Fund and Security Cash Fund (the
Funds) are registered under the Investment  Company Act of 1940, as amended,  as
diversified,  open-end management investment  companies.  The shares of Security
Income Fund are currently issued in five Series,  the Corporate Bond Series, the
U.S.  Government Series, the Limited Maturity Bond Series, the Global Aggressive
Bond  Series  and the High  Yield  Bond  Series,  with each  Series,  in effect,
representing  a separate  fund.  The Income Fund is required to account for each
Series separately and to allocate general expenses to each Series based upon the
net asset value of each Series.  The  following is a summary of the  significant
accounting  policies followed by the Funds in the preparation of their financial
statements.  These policies are in conformity with generally accepted accounting
principles.

     A. SECURITY  VALUATION -- Valuations of Income Fund's and Tax-Exempt Fund's
securities are supplied by pricing services  approved by the Board of Directors.
Securities listed or traded on a national  securities exchange are valued on the
basis of the last sales price.  If there are no sales on a particular  day, then
the  securities  are valued at the last bid price.  Securities  for which market
quotations are not readily available are valued by a pricing service considering
securities with similar yields,  quality,  type of issue,  coupon,  duration and
rating.  If  there  is no  bid  price  or if  the  bid  price  is  deemed  to be
unsatisfactory  by the Board of Directors or by the Fund's  investment  manager,
then the  securities  are  valued in good  faith by such  method as the Board of
Directors determines will reflect the fair value. The Funds' officers, under the
general supervision of the Board of Directors,  regularly review procedures used
by, and valuations provided by, the pricing service.

     Cash Fund,  by approval of the Board of  Directors,  utilizes the amortized
cost method for valuing portfolio securities, whereby all investments are valued
by reference to their  acquisition  cost as adjusted for amortization of premium
or accretion of discount.

     Generally, trading in foreign securities markets is substantially completed
each day at various times prior to the close of the New York Stock Exchange. The
values of foreign  securities  are  determined  as of the close of such  foreign
markets or the close of the New York Stock Exchange if earlier.  All investments
quoted  in  foreign  currency  are  valued in U.S.  dollars  on the basis of the
foreign currency  exchange rate prevailing at the close of business.  The Global
Aggressive Bond Series'  investments in foreign securities may involve risks not
present in domestic investments.  Since foreign securities may be denominated in
a  foreign  currency  and  involve   settlement  and  pay  interest  in  foreign
currencies,  changes in the relationship of these foreign currencies to the U.S.
dollar can significantly affect the value of the investments and earnings of the
Funds. Foreign investments may also subject the Global Aggressive Bond Series to
foreign  government  exchange  restrictions,  expropriation,  taxation  or other
political, social or economic developments, all of which could affect the market
and/or credit risk of the investments.

     B. FOREIGN CURRENCY TRANSACTIONS -- The accounting records of the Funds are
maintained in U. S. dollars.  All assets and liabilities  initially expressed in
foreign currencies are converted into U.S. dollars at prevailing exchange rates.
Purchases and sales of investment securities,  dividend and interest income, and
certain  expenses  are  translated  at the rates of exchange  prevailing  on the
respective dates of such transactions.

     The Funds  isolate that  portion of results of  operations  resulting  from
changes in foreign exchange rates on investments  from the fluctuations  arising
from changes in the market prices of securities held.

     Net realized foreign exchange gains or losses arise from sales of portfolio
securities,  sales of foreign  currencies,  and the difference between asset and
liability  amounts  initially  stated in foreign  currencies and the U.S. dollar
value of the amounts actually received or paid. Net unrealized  foreign exchange
gains or losses  arise from  changes in the value of  portfolio  securities  and
other assets and liabilities at the end of the reporting period,  resulting from
changes in the exchange rates.

     C. FORWARD FOREIGN  CURRENCY  EXCHANGE  CONTRACTS - Global  Aggressive Bond
Series may enter into forward  foreign  exchange  contracts in  connection  with
foreign currency risk from purchase or sale of securities denominated in foreign
currency.  The Series may also enter into such  contracts  to manage  changes in
foreign  currency  exchange rates on portfolio  positions.  These  contracts are
marked to market  daily,  by  recognizing  the  difference  between the contract
exchange  rate and the  current  market  rate as  unrealized  gains  or  losses.
Realized  gains or losses are  recognized  when  contracts  are  settled and are
reflected in the statement of operations. These contracts involve market risk in
excess of the amount reflected in the Balance Sheet. The face or contract amount
in U.S.  dollars  reflects the total exposure the Global  Aggressive Bond Series
has in that particular currency contract. Losses may arise due to changes in the
value of the foreign currency or if the counterparty  does not perform under the
contract.

     D. OPTIONS - The Global  Aggressive  Bond Series and High Yield Bond Series
may purchase  put and call options and write such options on a covered  basis on
securities   that  are   traded   on   recognized   securities   exchanges   and
over-the-counter markets. Call and put options on securities give the holder the
right to purchase or sell,  respectively  (and the writer the obligation to sell
or purchase),  a security at a specified  price, on or until a certain date. The
primary  risks  associate  with the use of options are an imperfect  correlation
between the change in market value of the securities  held by the Series and the
price of the option, the possibility of an illiquid market, and the inability of
the counter-party to meet the terms of the contract.

     The premium received for a written option is recorded as an asset,  with an
equal  liability  which is marked to market based on the  option's  quoted daily
settlement price.  Fluctuation in  the value of such instruments are recorded as
unrealized appreciation  (depreciation) until terminated, at which time realized
gains and losses are recognized. The Global Aggressive Bond Series wrote covered
call options during the year in which the Series received $7,179 in premiums.

     E. SECURITY  TRANSACTIONS AND INVESTMENT INCOME - Security transactions are
accounted for on the date the securities  are purchased or sold.  Realized gains
and  losses  are  reported  on an  identified  cost  basis.  Interest  income is
recognized on the accrual basis.  Premium and discounts  (except  original issue
discounts) on debt securities are not amortized, except Security Tax-Exempt Fund
which amortizes premiums.

     F.  DISTRIBUTIONS  TO  SHAREHOLDERS -  Distributions  to  shareholders  are
recorded on the ex-dividend date. The character of distributions made during the
year from net  investment  income or net  realized  gains may differ  from their
ultimate characterization for federal income tax purposes. These differences are
primarily due to the recharacterization of foreign currency gains and losses.

     G. TAXES - The Funds complied with the requirements of the Internal Revenue
Code applicable to regulated  investment  companies and distributed all of their
taxable net income and net realized  gains  sufficient to relieve them from all,
or substantially all, federal income, excise and state income taxes.  Therefore,
no provision for federal or state income tax is required.

     H. EARNINGS CREDITS - Under the fee schedule with the custodian,  the Funds
earn  credits  based on  overnight  custody  cash  balances.  These  credits are
utilized to reduce related custodial  expenses.  The custodian fees disclosed in
the  statement of  operations  do not reflect the  reduction in expense from the
related earnings credits.

     2. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

     Management fees are payable to Security Management Company, LLC (SMC) under
investment  advisory contracts at an annual rate of .50 of 1% of the average net
assets of each fund, except for Global Aggressive Bond Series and the High Yield
Bond Series  whose fees are .75 of 1% and .60 of 1% of the average net assets of
each Series,  respectively.  The  investment  advisory  contract for Income Fund
provides  that the total annual  expenses

                                       24

NOTES TO FINANCIAL STATEMENTS (CONTINUED)
- --------------------------------------------------------------------------------


of each Series of the Fund (including  management fees and custodian fees net of
earnings  credits,  but excluding  interest,  taxes,  brokerage  commissions and
extraordinary  expenses) will not exceed the level of expenses which Income Fund
is permitted to bear under the most restrictive  expense  limitation  imposed by
any state in which  shares  of the Fund are then  qualified  for  sale.  For the
period  ended  December  31,  1996,  SMC agreed to limit the total  expenses  of
Corporate Bond Series,  U.S.  Government Series and Limited Maturity Bond Series
to an annual rate of 1.1% of the average daily net asset value of Class A shares
and 1.85% of Class B shares of each respective  Series. SMC also agreed to limit
the total expenses of the Global  Aggressive Bond Series and the High Yield Bond
Series to 2.0% for Class A Shares and 2.75% for Class B shares. In addition, SMC
agreed  to waive  all of the  management  fees for the U.S.  Government  Series,
Limited Maturity Bond Series,  Global  Aggressive Bond Series and the High Yield
Bond Series until  December  31,  1996.  The  investment  advisory  contract for
Tax-Exempt and Cash Funds  provides that the total annual  expenses of the Funds
net of  custodian  fee  earnings  credits  will not exceed an amount equal to an
annual  rate of 1.0% of the  average  net  assets of Class A shares  and 2.0% of
Class B shares of the Tax-Exempt Fund as calculated on a daily basis.

     The Funds have entered into  contracts with SMC for transfer agent services
and certain other  administrative  services which SMC provides to the Funds. SMC
is paid an  annual  fixed  charge  per  account  and  shareholder  and  dividend
transaction fees.

     As the  administrative  agent for the Funds,  SMC  performs  administrative
functions,  such as  regulatory  filings,  bookkeeping,  accounting  and pricing
functions for the Funds. For this service SMC receives on an annual basis, a fee
of .09 percent of the average  daily net assets of Corporate  Bond Series,  U.S.
Government  Series,  Limited Maturity Bond Series,  High Yield Bond Series,  and
Tax-Exempt  Fund and .045  percent of the average  daily net assets of Cash Fund
and Global Aggressive Bond Series, calculated daily and payable monthly. For the
identified administrative services SMC also receives, with respect to the Global
Aggressive Bond Series, an annual fee equal to the greater of .10 percent of its
average net assets or (i) $45,000 in the year ending  April 29,  1997;  and (ii)
$60,000 thereafter.

     SMC pays the Sub-Advisor,  Lexington Management Corporation (LMC) an annual
fee in an amount  equal to .35% of the average  net assets of Global  Aggressive
Bond  Series,  for  investment  advisory  and  certain  administrative  services
provided  to the  Global  Aggressive  Bond  Series.  LMC  agreed  to  waive  its
sub-advisory  fee until  December 31, 1996. The  Sub-Advisor  has entered into a
sub-advisory  contract with MFR Advisors,  Inc.,  ("MFR"),  under which MFR will
provide the Global  Aggressive Bond Series with investment and economic research
services. For the service provided by MFR, MFR receives from the Sub-Advisor,  a
fee equal to .15% of the average daily net assets of the Global  Aggressive Bond
Series.

     Income and Tax-Exempt Funds have adopted  Distribution Plans related to the
offering of Class B shares  pursuant to Rule 12b-1 under the Investment  Company
Act of 1940.  The Plans  provide  for  payments at an annual rate of 1.0% of the
average net assets of Class B shares.  Class A shares of Income Fund incur 12b-1
distribution  fees at an annual  rate of .25% of the  average net assets of each
Series.

     Security  Distributors,  Inc. (SDI), a wholly-owned  subsidiary of Security
Benefit  Group,  Inc.,  a  financial  services  holding  company,   is  national
distributor  for Income a nd  Tax-Exempt  Funds.  SDI received net  underwriting
commissions on sales of Class A shares and contingent  deferred sales charges on
redemptions  occurring within 5 years of the date of purchase of Class B shares,
after  allowances to brokers and dealers for the period ended December 31, 1996,

directors of Security Benefit Life Insurance Company and its subsidiaries, which
include SMC and SDI.

     6. TAX STATUS OF DIVIDENDS

     Except for tax-exempt dividends, the income dividends paid by the Funds are
taxable as ordinary income on the shareholders' tax returns.  None of the amount
taxable as ordinary  income for the Funds  qualifies for the dividends  received
deduction available to corporate  shareholders in accordance with the provisions
of the Internal Revenue Code.

     None of the exempt-interest dividends paid by Security Tax-Exempt Fund have
been determined to be attributable to interest from specified  private  activity
bonds.  Thus, no portion is required to be reported as a tax preference  item on
Form 4626 or 6251, as appropriate.

     In some states,  the portion of ordinary income  dividends  attributable to
the Funds'  investment in direct  obligations of the U.S.  Government may not be
subject to state  taxation.  For the year ended  December 31, 1996,  interest on
U.S. Government obligations as a percentage of gross investment income was: Cash
Fund, 5%;  Corporate  Bond Series,  6%; U.S.  Government  Series,  28%;  Limited
Maturity  Bond Series,  6%; and Global  Aggressive  Bond  Series,  1%. Since the
qualifications  for such exemption  vary state by state,  we suggest you consult
your tax advisor for applicability.



REPORT OF INDEPENDENT AUDITORS
- --------------------------------------------------------------------------------

TO THE SHAREHOLDERS AND BOARD OF DIRECTORS
SECURITY INCOME FUND, SECURITY TAX-EXEMPT FUND
AND SECURITY CASH FUND

     We have audited the accompanying  balance sheets,  including the statements
of net assets of Security Income Fund (comprising,  respectively,  the Corporate
Bond, U.S.  Government,  Limited Maturity Bond,  Global Aggressive Bond and High
Yield Bond Series),  Security Tax-Exempt Fund and Security Cash Fund (the Funds)
as of December 31, 1996, the related  statements of  operations,  changes in net
assets and the financial  highlights for the periods  indicated  therein.  These
financial  statements and the financial highlights are the responsibility of the
Funds'  management.  Our  responsibility  is to  express  an  opinion  on  these
financial statements and financial highlights based on our audits.

     We have conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about whether the financial  statements and the financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements and financial  highlights.  Our procedures  included  confirmation of
investments owned as of December 31, 1996, by correspondence with the custodian.
As to securities relating to uncompleted transactions,  we performed other audit
procedures.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

     In our opinion,  the financial statements and financial highlights referred
to above present fairly,  in all material  respects,  the financial  position of
each of the Funds  (including  each of the Series of  Security  Income  Fund) at
December 31,  1996,  and the results of their  operations,  changes in their net
assets  and the  financial  highlights  for the  periods  indicated  therein  in
conformity with generally accepted accounting principles.

PRESIDENT'S LETTER
AUGUST 15, 1997


To Our Shareholders:

The first six months of 1997 have been a  roller-coaster  ride for fixed  income
investors. At the beginning of the year the bellwether thirty-year Treasury bond
yielded  6.64%.  By late April the yield had risen to 7.14%  before it began its
descent to 6.78% at the end of June. As you know,  bond prices move inversely to
yields,  staging a "mirror"  roller  coaster  ride  which  produced a 2.3% total
return on the long Treasury bond for the period.

THE INFLATION STORY IN 1997

Contrary to what this volatility  might indicate,  the compelling  story for the
six-month period was the absence of  reacceleration of inflation  pressures.  In
fact,  evidence  suggests  that  inflation is actually  declining.  This is true
particularly  when one  takes  into  account  the  overstatement  of  structural
inflation  revealed by the Boskin report,  the study  commissioned by the Senate
Finance  Committee to review the  calculation of the Consumer Price Index (CPI).
This report found that the CPI probably overstates true increases in the cost of
living by approximately 1.1% per year.

This  leaves  us with the  understanding  that real  interest  rates on the long
Treasury  bond are 300 to 400 basis points  higher than might be expected  given
today's actual  annualized  inflation  rate of around 2%. We therefore  conclude
that there is  opportunity  for further  declines in long-term  rates with their
commensurate increase in bond prices as we move through the second half of 1997.

CAN THE GOOD NEWS CONTINUE?

The good news on the inflation front should continue to be a positive  influence
on fixed  income  markets  for some time as the  economy  continues  to slow its
growth rate from the torrid pace of 1997's first quarter. We believe that due to
the  continuation of  productivity  improvements  in U.S.  businesses,  economic
growth rates of around 3% may be sustainable without reigniting inflation.  This
is in  contrast  to the 2% to 2.5% rates of growth  that have been  historically
viewed by the Federal  Reserve  Board as a "speed  bump."  Therefore,  for fixed
income investors the climate should remain favorable for returns of at least the
portfolio coupon rate, with the possibility of some capital appreciation if long
term  interest  rates  decline as we believe they will,  in  recognition  of the
pattern of slowing global inflation pressures.

As always,  we appreciate your  continuing  investment in the Security Funds. We
invite your questions and comments at any time.

MANAGER'S COMMENTARY
AUGUST 15, 1997


SECURITY INCOME FUND
CORPORATE BOND SERIES

Volatility  was the key word for fixed income market  behavior in the first half
of 1997.  The  thirty-year  Treasury  bond  began  the year  yielding  6.64% and
finished  June at  6.78%.  In the  intervening  months it rose as high as 7.14%,
managing to gain only 2.3% in total return over the six months. Corporate issues
fared  slightly  better,  as the Lehman  Corporate  Bond Index rose  3.07%.  The
Corporate Bond Series of Security  Income Fund generated a positive total return
for the six-month  period of 2.35%,  slightly  lagging its peer group average of
2.68%.(1)

CONTRIBUTORS TO PERFORMANCE IN THE FIRST HALF

The Series  underperformed in the first quarter of 1997 primarily because of its
position in property and casualty insurer Home Holdings. This company, which was
beset with problems among some of its insured risks, continued to lose value and
was ultimately sold from the portfolio.

While the first quarter's total return was negative, the second quarter was much
improved.  Steps  were  taken to  upgrade  the  overall  credit  quality  of the
holdings.  The high yield portion of the portfolio is now concentrated in issues
rated BB and B, the upper tiers of the high yield rating universe. Some of these
issues have the  potential  to be upgraded to  investment  grade  ratings in the
not-too-distant  future, which should add a capital gain return element to their
attractive coupon rates.

HOW THE PORTFOLIO LOOKS NOW

The sector  composition of the portfolio at the end of June was about 53.5% high
grade  corporate  bonds,   20%  high  yield  issues,   17%  Yankee  bonds  (U.S.
dollar-denominated   securities  issued  by  foreign  corporations),   and  9.5%
mortgage-backed bonds issued primarily by agencies of the U.S. Government.  This
sector  diversification gives the portfolio some downside protection because the
various sectors will not always move up or down in value in tandem.

The average  rating of the portfolio is a strong BBB, and the average  coupon of
the portfolio holdings is 7.92%. Average duration of the securities is about 6.6
years,  slightly longer than that of the benchmark  Lehman  Corporate Bond Index
duration of 5.88 years. We are working to reduce the block size of issues in the
portfolio so that each issuer will  represent  2.5% or less of total assets,  in
order to achieve further diversification.

LOOKING TO THE SECOND HALF

The Corporate Bond Series'  portfolio is well  positioned for the coming months.
Our emphasis on upgrading credit quality should help bring total returns more in
line with those of the benchmark index. Diversification among sectors and rating
classes can add a further element of safety. The mortgage-backed  securities and
Yankee bonds provide cash flow through their  generally  higher coupon  interest
rates than other classes.  Finally,  fundamentally  improving  stories among our
high yield credits  provide the potential for additional  return through capital
gains.

MANAGER'S COMMENTARY
AUGUST 15, 1997



U.S. GOVERNMENT SERIES

The U.S.  Government  Series of Security Income Fund returned 2.46% in the first
half of 1997,  right in line with its peer group  average  return of 2.47%.1 The
benchmark Lehman Government Bond Index returned a slightly higher 2.63% over the
same period.

CONTRIBUTORS TO PERFORMANCE

The portfolio had a large  weighting in  longer-duration  Federal  agency bonds,
with  moderate   positions  in  shorter  Treasury  issues  and   mortgage-backed
securities  throughout  the first six  months.  During  the  first  quarter  the
Treasuries and  mortgage-backed  bonds provided downside  protection and allowed
the total return to be higher  (actually,  less  negative) than that of the peer
group of funds. In March, April and May, however, the bond markets recovered and
these same defensive  issues  dampened  returns  somewhat,  holding back overall
performance.

PORTFOLIO COMPOSITION AT THE END OF THE FIRST HALF

The sector weighting in the Series  consisted of 41% federal agency  securities,
36% GNMA mortgage-backed bonds secured by home mortgages,  and 23% U.S. Treasury
issues.  In general,  mortgage-backed  bonds and  federal  agency  issues  carry
slightly higher coupon rates than comparable  Treasury bonds.  This adds a small
extra increment to total return.

The duration of the  portfolio at the end of June was 4.85 years,  close to that
of the benchmark  index's duration of 4.78 years.  The average coupon,  however,
was  considerably  higher  than that of the index at  8.15%,  compared  with the
benchmark's 6.95% average.

PLANS FOR THE NEXT SIX MONTHS

The U.S. Government Series is designed for conservative investors, with a strong
emphasis on credit  quality of the  securities  held in the  portfolio.  Because
shareholders  in the Series tend to be  cautious,  we don't try to outguess  the
markets by  dramatically  lengthening  or  shortening  the duration of portfolio
holdings.

In the coming months, we anticipate  maintaining our sector allocations close to
their  present  levels.  We expect  portfolio  durations to also remain close to
current  lengths.  As always,  we keep an eye on the  markets to watch for sharp
movements in either  direction,  and retain the ability to make  stronger  moves
than usual if it becomes necessary.

MANAGER'S COMMENTARY
AUGUST 15, 1997


LIMITED MATURITY BOND SERIES

Throughout a period of volatility in the bond markets, the Limited Maturity Bond
Series  performed  very well in the first half of 1997.  The  Series  produced a
total return of 3.20%, comparing favorably with its peer group average of 2.74%,
and  outperforming  its benchmark  Lehman Brothers  Intermediate  Corporate Bond
Index return of 3.05%.(1)  The ten-year  Treasury  bond,  representative  of the
maturity  structure of this portfolio,  began the year yielding  6.42%,  touched
6.90% in late  March and early  April,  and fell back to close the first half at
6.50%.

CONTRIBUTORS TOWARD STRONG PERFORMANCE

Several of the high yield holdings in the portfolio  experienced strong earnings
and  strengthened  balance  sheets  through  debt  reduction  over the first six
months. These include PanAmerican Beverages, Inc., a Latin American producer and
bottler of Coca Cola and other soft drinks. Valassis Communications Corporation,
a company  that  produces  special  coupon  inserts  for Sunday  newspapers,  is
generally  expected to be upgraded to investment  grade in the near future after
reducing expenses and benefiting from lower paper costs.

Seagull Energy Corporation,  an oil and gas explorer and developer,  has lowered
overall company costs, realizing benefits of a recent acquisition.  It is now on
Standard & Poor's  ratings  watch list for an upgrade.  Comcast  Corporation,  a
cable television and  telecommunications  company, was upgraded to BB just after
the close of the first half.

COMPOSITION OF THE PORTFOLIO

The Limited Maturity Bond Series is currently  comprised of about 46% high grade
bonds, 23% high yield issues (the maximum high yield allocation permitted in the
portfolio is 25%), 22%  mortage-backed  securities  issued  primarily by Federal
government agencies,  and 9% Yankee bonds (dollar denominated  securities issued
by foreign corporations).

The portfolio duration is approximately 4.3 years, just slightly longer than the
benchmark  index's 4.21 years.  The average  coupon is a  relatively  high 8.1%,
lifted by the high yield and mortgage-backed  securities  holdings.  The average
rating of securities remains well within the investment grade  classification at
a mid-A level.

WHAT'S AHEAD FOR THE LIMITED MATURITY PORTFOLIO

We plan to maintain the overall  portfolio  quality at its present level, and to
keep the duration  close to that of the benchmark  intermediate  corporate  bond
index. The broad diversification of asset classes should help keep volatility at
lower levels, since the various sectors will not always move up or down in value
in tandem with each other.  The  intermediate-maturity  bond  portfolios tend to
outperform their longer counterparts in periods of rising interest rates, and so
make an attractive investment medium for a portion of shareholders' fixed income
allocations.

MANAGER'S COMMENTARY
AUGUST 15, 1997


HIGH YIELD SERIES

The high  yield  segment of the fixed  income  markets  was the  best-performing
domestic bond sector during the first half of 1997. The High Yield Series ranked
above  median in its peer group,  returning  5.79% for the  period.(1)  The peer
group average return was 5.92%,  while the benchmark  Lehman Brothers High Yield
Index posted a return of 5.82%.

COMPOSITION OF THE PORTFOLIO

At the end of June the High Yield  Series  portfolio  was  skewed  toward the BB
rating  category,  the highest level on the high yield bond rating  scale.  With
approximately 70% of the issues in this category and the remaining ones rated B,
we feel  that  there is less  concern  about  credit  risk and more  ability  to
liquidate easily should selling become  necessary.  Our analysts seek out issues
which are currently  rated BB, but whose financial  statements show  improvement
that could lead to an upgrade to investment grade in the near future.

Throughout the six months the portfolio has been underweight in basic industries
such  as  mining,   metals,  and  chemicals,   which  have  for  the  most  part
underperformed  other sectors.  We were overweight in consumer  cyclicals (cable
television  companies,   retail  stores,  gaming,  and  home  construction)  and
financials, including banks and insurance companies. Our underweight position in
utility bonds hurt, as this sector did very well during the period.

CONTRIBUTORS TO STRONG PERFORMANCE

Some  issues  in the  portfolio  were  upgraded  by the  major  rating  agencies
recently.  Knoll,  Inc., which  manufactures and distributes  office systems and
business furniture,  brought an initial public offering (IPO) to market and used
the proceeds to pay down more  expensive  debt.  The company's  securities  were
subsequently  upgraded from a low B to a high B level.  Comcast  Corporation,  a
cable television and  telecommunications  company, was upgraded to BB just after
the close of the first half of 1997.

Other strong performers included AGCO Corporation,  a worldwide manufacturer and
distributor of agricultural  equipment and related  replacement  parts. AGCO has
benefited  from the strong  farm  economy,  both in the U.S.  and  abroad.  Four
Seasons Hotels, Inc. offered to repurchase its 9.125% notes at a price which was
very attractive relative to their cost in our portfolio.

PLANS FOR THE REST OF 1997

We intend to continue  our strategy of staying  cognizant of credit  quality and
looking for bonds which have a potential of being upgraded from BB to investment
grade.  The high yield bond  markets are  similar to the equity  markets in that
they have risen a good deal, but  investment  funds continue to pour in, driving
them up further.  We plan to structure  the  portfolio to be sound from a credit
standpoint so that it can better withstand any unforseen shocks to the market.

MANAGER'S COMMENTARY
AUGUST 15, 1997


SECURITY TAX-EXEMPT FUND

The  municipal  market in the first half of the year  outperformed  its  taxable
counterparts in the domestic fixed income markets. The Lehman Brothers Municipal
Bond Index rose 3.20% during the period, outpacing the Lehman Brothers Aggregate
Fixed Income Index return of 3.09%.  The corporate and government  components of
the aggregate index also showed lower returns than those of the municipal index.

PORTFOLIO PERFORMANCE IN THE FIRST HALF

The Security Tax-Exempt Fund produced a positive total return of 2.58%, modestly
underperforming  its peer  group  average  of 2.95% for the six  months.(1)  Our
somewhat  shorter  duration  of 6.9 years,  compared  with the  benchmark  index
duration  of  7.42  years,  held  back  performance  in the  latter  part of the
six-month  period when interest rates were falling.  Longer  maturities  tend to
outperform shorter bonds in such an interest rate environment.

The average credit quality of the bonds in the portfolio,  currently at a mid-AA
level, while providing comfort to investors because of its strength,  also holds
back  performance  when interest  rates are declining.  We generally  maintain a
higher-than-average   portfolio  rating  since  financial  information  on  many
municipal  issuers is difficult to obtain,  and  sometimes  not timely enough to
protect  investors when finances  deteriorate.  In addition,  if  municipalities
experience  strains on their budgets when Congress "pushes down" budget items to
the state and local levels,  those bonds with higher credit  quality should hold
their value better.

THE COMPOSITION OF THE PORTFOLIO CURRENTLY

The  Security  Tax-Exempt  Fund  seeks  to  add  a  measure  of  safety  through
diversification. In municipal portfolios, this means including a large number of
geographic  locations  as well as  diversifying  by  industry.  At June 30,  the
holdings  represented  17 states  plus the  District  of  Columbia.  The largest
represented,  in terms of  market  value of the  bonds,  was  Washington  State,
followed by Illinois and California.

In terms of industry  classification,  the  largest  grouping of bonds is in the
Education  Revenue  sector.  Education  issues  are  viewed  favorably  by  most
municipal bond holders,  since municipalities are highly likely to support their
school systems and avoid bond defaults in this area.  Second largest is Electric
Utility Revenue,  another area where cash inflows to retire bonds are considered
relatively stable.

OUTLOOK FOR MUNICIPAL BONDS

A  constant  threat  to the  value of tax  exempt  bonds is talk of tax  bracket
reductions.  While various tax "breaks" are under discussion in Congress as they
try to agree on a balanced budget package,  a lowering of tax brackets for those
individuals  most likely to invest in  municipal  bonds  seems  unlikely at this
time. We believe that tax exempt bonds  continue to be an attractive  investment
for taxpayers in the upper brackets, and should be for some time to come.

MANAGER'S COMMENTARY
AUGUST 15, 1997


SECURITY CASH FUND

The total  return on money  market funds in the first half of 1997 was near that
of its close relatives, the fixed income funds, as interest rates on thirty-year
Treasury bonds  fluctuated in a range roughly between 6.50% and 7.25%.  Security
Cash Fund posted a gain of 2.36% for the period,  very near the 2.38% peer group
average yield.  Money market funds,  unlike longer-term fixed income securities,
generally  benefit from  increases in short-term  interest rates such as the one
executed by the Federal Reserve Open Market Committee in March.

AVERAGE MATURITY TARGETS FOR THE FUND

At June 30, the Cash Fund had a 61-day average maturity,  seven days longer than
that of the benchmark IBC Donoghue Money Fund Report. Our goal is to stay within
ten days more or less than the Donoghue average and avoid trying to outguess the
markets  by  moving  maturities  sharply  shorter  or  longer.  Because  of  the
short-maturity  nature of money market assets we can quickly  adjust to interest
rate changes when they occur,  without taking unnecessary  maturity risk in this
conservative portfolio.

ASSET SECTORS REPRESENTED IN THE PORTFOLIO

The assets in Security Cash Fund at the end of the six-month period consisted of
76%  commercial  paper,  15% federal agency  securities,  and 11% Small Business
Administration  issues. The commercial paper we purchase is entirely in the "top
tier" of rating agency classifications, rated at least A1 by Standard and Poor's
rating agency or P1 by Moody's.  Federal  agency  holdings may from time to time
include   short-term   securities   issued  by  the  Federal  National  Mortgage
Association, the Federal Home Loan Bank, and Federal Farm Credit Banks.

The Small  Business  Association  (SBA)  holdings  are fully  guaranteed  by the
federal government as to timely payment of principal and interest. These issues,
while  bearing  stated  maturities  in the  twenty- to  thirty-year  range,  are
considered  to be  short-maturity  paper  because  their  interest  rate  resets
periodically  (usually  monthly or quarterly).  This enables the issues to carry
coupons  representing  recent  market  levels,  staying  competitive  with other
short-term investment instruments.

OUTLOOK FOR THE NEXT SIX MONTHS

Interest  rates have recently been declining on long-term  bonds.  Although this
movement has some effect on short-term rates,  until the Federal Reserve decides
to lower their short rate targets,  commercial paper and  short-maturity  agency
interest  rates  should not drop  substantially.  We expect the Fed to  maintain
their  cautious  stance  toward a  rekindling  of  inflationary  pressures,  and
therefore  believe that money fund returns  will not vary  substantially  in the
near future.

Fixed Income Team

The Security Cash Fund is neither insured nor guaranteed by the U.S.  Government
and there is no  assurance  that the fund will be able to  maintain a stable net
asset value of $1.00 per share.

NOTES TO FINANCIAL STATEMENTS
JUNE 30, 1997
(UNAUDITED)


1.  SIGNIFICANT ACCOUNTING POLICIES

     Security Income Fund,  Security Tax-Exempt Fund and Security Cash Fund (the
Funds) are registered under the Investment  Company Act of 1940, as amended,  as
diversified  open-end management  investment  companies.  The shares of Security
Income  Fund are  currently  issued in multiple  series,  with each  series,  in
effect, representing a separate Fund. The Income Fund is required to account for
each series  separately  and to allocate  general  expenses to each series based
upon the net asset  value of each  series.  The  following  is a summary  of the
significant  accounting  policies  followed by the Funds in the  preparation  of
their  financial  statements.  These  policies are in conformity  with generally
accepted accounting principles.

     A. SECURITY  VALUATION - Valuations of Income Funds' and Tax-Exempt  Fund's
securities are supplied by pricing services  approved by the Board of Directors.
Securities listed or traded on a national  securities exchange are valued on the
basis of the last sales price.  If there are no sales on a particular  day, then
the  securities  are valued at the last bid price.  Securities  for which market
quotations are not readily available are valued by a pricing service considering
securities with similar yields,  quality,  type of issue,  coupon,  duration and
rating.  If  there  is no  bid  price  or if  the  bid  price  is  deemed  to be
unsatisfactory  by the Board of Directors or by the Funds'  investment  manager,
then the  securities  are  valued in good  faith by such  method as the Board of
Directors determines will reflect the fair value. The Funds' officers, under the
general supervision of the Board of Directors,  regularly review procedures used
by, and valuations provided by, the pricing service.

     Cash Fund,  by approval of the Board of  Directors,  utilizes the amortized
cost method for valuing portfolio securities, whereby all investments are valued
by reference to their  acquisition  cost as adjusted for amortization of premium
or accretion of discount.

     B.  OPTIONS - The High Yield bond Series may  purchase put and call options
and write  such  options  on a covered  basis on  securities  that are traded on
recognized  securities  exchanges  and  over-the-counter  markets.  Call and put
options  on  securities   give  the  holder  the  right  to  purchase  or  sell,
respectively (and the writer the obligation to sell or purchase),  a security at
a specified  price,  on or until a certain date.  The primary risks  associate d
with the use of  options  are an  imperfect  correlation  between  the change in
market value of the  securities  held by the Series and the price of the option,
the possibility of an illiquid market, and the inability of the counter-party to
meet the terms of the contract.

     The premium received for a written option is recorded as an asset,  with an
equal  liability  which is marked to market based on the  option's  quoted daily
settlement  price.  Fluctuation in the value of such instruments are recorded as
unrealized appreciation  (depreciation) until terminated, at which time realized
gains and losses are recognized.

     C. SECURITY  TRANSACTIONS AND INVESTMENT INCOME - Security transactions are
accounted for on the date the securities  are purchased or sold.  Realized gains
and  losses  are  reported  on  an  identified  cost  basis.Interest  income  is
recognized on the accrual basis.  Premium and discounts  (except  original issue
discounts) on debt securities are not amortized, except Security Tax-Exempt Fund
which amortizes premiums.

     D.  DISTRIBUTIONS  TO  SHAREHOLDERS -  Distributions  to  shareholders  are
recorded on the ex-dividend date. The character of distributions made during the
year from net  investment  income or net  realized  gains may differ  from their
ultimate characterization for federal income tax purposes. These differences are
primarily due to the recharacterization of foreign currency gains and losses.

     E. TAXES - The Funds complied with the requirements of the Internal Revenue
Code applicable to regulated  investment  companies and distributed all of their
taxable net income and net realized  gains  sufficient to relieve them from all,
or substantially all, federal income, excise and state income taxes.  Therefore,
no provision for federal or state income tax is required.

     F. EARNINGS CREDITS - Under the fee schedule with the custodian,  the Funds
earn  credits  based on  overnight  custody  cash  balances.  These  credits are
utilized to reduce related custodial  expenses.  The custodian fees disclosed in
the  statement of  operations  do not reflect the  reduction in expense from the
related earnings credits.

2.  MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

     Management fees are payable to Security Management Company, LLC (SMC) under
investment  advisory contracts at an annual rate of .50 of 1% of the average net
assets of each fund, except for the High Yield Bond Series whose fees are .60 of
1% of the average net assets of the Series. The investment advisory contract for
Income Fund provides  that the total annual  expenses of each Series of the Fund
(including  management  fees and  custodian  fees net of earnings  credits,  but
excluding interest,  taxes,  brokerage  commissions and extraordinary  expenses)
will not exceed the level of expenses  which  Income Fund is  permitted  to bear
under the most  restrictive  expense  limitation  imposed  by any state in which
shares of the Fund are then  qualified  for sale.  For the period ended  June30,
1997,  SMC agreed to limit the total  expenses of Corporate  Bond  Series,  U.S.
Government  Series and Limited Maturity Bond Series to an annual rate of 1.1% of
the average  daily net asset value of Class A shares and 1.85% of Class B shares
of each  respective  Series.  SMC also agreed to limit the total expenses of the
High Yield Bond  Series to 2.0% for Class A Shares and 2.75% for Class B shares.
In  addition,  SMC  agreed  to  waive  all of the  management  fees for the U.S.
Government  Series,  Limited Maturity Bond Series and the High Yield Bond Series
until  December 31, 1997. The  investment  advisory  contract for Tax-Exempt and
Cash Funds provides that the total annual expenses of the Funds net of custodian
fee  earnings  credits will not exceed an amount equal to an annual rate of 1.0%
of the  average  net  assets of Class A shares and 2.0% of Class B shares of the
Tax-Exempt Fund as calculated on a daily basis.

     The Funds have entered into  contracts with SMC for transfer agent services
and certain other  administrative  services which SMC provides to the Funds. SMC
is paid an  annual  fixed  charge  per  account  and  shareholder  and  dividend
transaction fees.

     As the  administrative  agent for the Funds,  SMC  performs  administrative
functions, such as regulatory filings, bookkeeping,

                                       26

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

accounting and pricing functions for the Funds. For this service SMC receives on
an annual basis, a fee of .09% of the average daily net assets of Corporate Bond
Series,  U.S.  Government Series,  Limited Maturity Bond Series, High Yield Bond
Series,  and  Tax-Exempt  Fund and .045% of the average daily net assets of Cash
Fund calculated daily and payable monthly.

     Income and Tax-Exempt Funds have adopted  Distribution Plans related to the
offering of Class B shares  pursuant to Rule 12b-1 under the Investment  Company
Act of 1940.  The Plans  provide  for  payments at an annual rate of 1.0% of the
average net assets of Class B shares.  Class A shares of Income Fund incur 12b-1
distribution  fees at an annual  rate of .25% of the  average net assets of each
Series.

     Security  Distributors,  Inc. (SDl), a wholly-owned  subsidiary of Security
Benefit  Group,  Inc.,  a  financial  services  holding  company,   is  national
distributor  for Income and  Tax-Exempt  Funds.  SDI received  net  underwriting
commissions  on sales of Class A shares and  contingent  deferred  sales charges
(CDSC) on redemptions  occurring within 5 years of the date of purchase of Class
B shares,  after  allowances to brokers and dealers for the period ended June30,
1997, in the amounts presented below:

               his/her status as a Director or officer of the Corporation or, if
               serving at the  request  of the  Corporation,  as a  Director  or
               officer of another corporation.  The indemnification  provided by
               this bylaw  provision  shall not be exclusive of any other rights
               to which those  indemnified may be entitled under the Articles of
               Incorporation, under any other bylaw or under any agreement, vote
               of  stockholders  or  disinterested  directors or otherwise,  and
               shall not limit in any way any right  which the  Corporation  may
               have to make different or further indemnification with respect to
               the same or different persons or classes of persons.

               No  person  shall be  liable  to the  Corporation  for any  loss,
               damage,  liability  or expense  suffered  by it on account of any
               action  taken or omitted to be taken by him/her as a director  or
               officer of the Corporation or of any other  corporation  which he
               serves  as  a  Director   or  officer  at  the   request  of  the
               Corporation, if such

<PAGE>

               person  (a)  exercised  the same  degree  of care and  skill as a
               prudent man would have exercised under the  circumstances  in the
               conduct of his/her  own  affairs,  or (b) took or omitted to take
               such  action  in   reliance   upon  advice  of  counsel  for  the
               Corporation,  or for such other  corporation,  or upon  statement
               made or information furnished by Directors,  officers,  employees
               or agents of the Corporation, or of such other corporation, which
               he/she had no reasonable grounds to disbelieve.

          In the event any provision of this Section 30 shall be in violation of
          the  Investment  Company Act of 1940, as amended,  or of the rules and
          regulations promulgated  thereunder,  such provisions shall be void to
          the extent of such violations.

          On April 22, 1988, the  shareholders  approved the Board of Directors'
          recommendation  that the  Articles  of  Incorporation  be  amended  by
          adopting the following Article Fifteenth:

               "A director shall not be personally  liable to the corporation or
               to its  stockholders for monetary damages for breach of fiduciary
               duty  as a  director,  provided  that  this  sentence  shall  not
               eliminate nor limit the liability of a director:

               A.  for  any  breach  of  his  or  her  duty  of  loyalty  to the
                   corporation or to its stockholders;

               B.  for acts or  omissions  not in good  faith  or which  involve
                   intentional misconduct or a knowing violation of law;

               C.  for any unlawful dividend, stock purchase or redemption under
                   the provisions of Kansas Statutes  Annotated (K.S.A.) 17-6424
                   and amendments thereto; or

               D.  for any  transaction  from  which  the  director  derived  an
                   improper personal benefit."

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

                          INVESTMENT ADVISORY CONTRACT

THIS AGREEMENT,  made this 7th day of October, 1983, between SECURITY TAX-EXEMPT
FUND, a Kansas corporation (hereinafter referred to as the "Fund"), and SECURITY
MANAGEMENT  COMPANY,  a  Kansas  corporation  (hereinafter  referred  to as  the
"Management Company");

                                   WITNESSETH:

WHEREAS, the Fund is engaged in business as an open-end,  management  investment
company  registered under the Federal  Investment Company Act of 1940 (the "1940
Act"); and

WHEREAS,  the Company is authorized to issue shares of capital stock in separate
Series, with each such Series representing  interests in a separate portfolio of
securities and other assets; and

WHEREAS,  the  Company  intends  initially  to offer  shares in one series to be
designated Security Tax-Exempt Fund (the "Initial Series"), such series together
with all other series  subsequently  established  by the Company with respect to
which the Company desires to retain the Management  Company to render investment
advisory services  hereunder and with respect to which the Management Company is
willing so to do, being herein collectively referred to as the "Series", and

WHEREAS,  the Management Company is willing to provide  investment  research and
advice to the Fund on the terms and conditions hereinafter set forth;

NOW,  THEREFORE,  in  consideration  of the premises and mutual  agreements made
herein, the parties hereto agree as follows:

1.  EMPLOYMENT OF MANAGEMENT  COMPANY.  The Fund hereby  employs the  Management
    Company to act as investment  adviser to the Initial  Series with respect to
    the  investment of its assets,  and to supervise and arrange the purchase of
    securities  for the Initial  Series and the sale of  securities  held in the
    portfolio of the Initial  Series,  subject always to the  supervision of the
    board of  directors  of the Fund (or a duly  appointed  committee  thereof),
    during the period and upon and  subject to the terms and  conditions  herein
    set forth. The Management  Company hereby accepts such employment and agrees
    to perform the  services  required by this  Agreement  for the  compensation
    herein provided.

    In the event the  Company  establishes  one or more  series  other  than the
    Initial  Series  with  respect to which it desires to retain the  Management
    Company to render investment  advisory services  hereunder,  it shall notify
    the Management  Company in writing.  If the Management Company is willing to
    render such services it shall notify the Company in writing,  whereupon such
    series shall become a Series subject to the terms and conditions  hereunder,
    and to such amended or additional provisions as shall be specifically agreed
    to by the Company and the Management  Company in accordance  with applicable
    law.

<PAGE>

2.  INVESTMENT  ADVISORY DUTIES.  The Management Company shall regularly provide
    each Series with investment research,  advice and supervision,  continuously
    furnish an  investment  program  and  recommend  which  securities  shall be
    purchased  and sold and what  portion of the assets of each series  shall be
    held  uninvested  and  arrange  for the  purchase  of  securities  and other
    investments  held in the  portfolio of each Series.  All  investment  advice
    furnished  by the  Management  Company to each Series  under this  Section 2
    shall at all times conform to any requirements  imposed by the provisions of
    the  Fund's  Articles  of  Incorporation  and  Bylaws,  the  1940  Act,  the
    Investment  Advisors Act of 1940 and the rules and  regulations  promulgated
    thereunder,  any other  applicable  provisions  of law, and the terms of the
    registration  statements of the Fund under the Securities Act of 1933 ("1933
    Act") and the 1940 Act,  all as from time to time  amended.  The  Management
    Company  shall advise and assist the officers or other agents of the Fund in
    taking such steps as are necessary or appropriate to carry out the decisions
    of the  board of  directors  of the Fund (and any duly  appointed  committee
    thereof) with regard to the foregoing matters and the general conduct of the
    Fund's business.

3.  PORTFOLIO TRANSACTIONS AND BROKERAGE.

    (a)  Transactions  in  portfolio   securities   shall  be  effected  by  the
         Management  Company,  through  brokers  or  otherwise,  in  the  manner
         permitted  in this  Section  3 and in  such  manner  as the  Management
         Company  shall  deem to be in the  best  interests  of the  Fund  after
         consideration is given to all relevant factors.

    (b)  In  reaching a judgment  relative to the  qualification  of a broker to
         obtain the best execution of a particular  transaction,  the Management
         Company may take into account all relevant  factors and  circumstances,
         including the size of any  contemporaneous  market in such  securities;
         the  importance  to the  Fund of speed  and  efficiency  of  execution;
         whether the particular  transaction is part of a larger intended change
         in  portfolio   position  in  the  same   securities;   the   execution
         capabilities   required  by  the   circumstances   of  the   particular
         transaction;  the  capital  required  by the  transaction;  the overall
         capital strength of the broker;  the broker's apparent  knowledge of or
         familiarity  with  sources  from  or to  whom  such  securities  may be
         purchased  or  sold;  as  well  as  the  efficiency,   reliability  and
         confidentiality  with which the broker has  handled  the  execution  of
         prior similar transactions.

    (c)  Subject  to any  statements  concerning  the  allocation  of  brokerage
         contained  in  the  Fund's   prospectus,   the  Management  Company  is
         authorized  to direct the execution of portfolio  transactions  for the
         Fund to brokers who furnish investment information or research services
         to the Management Company. Such allocation shall be in such amounts and
         proportions as the Management  Company may determine.  If a transaction
         is directed to a broker  providing  brokerage and research  services to
         the Management Company, the commission paid for such transaction may be
         in excess of the  commission  another  broker  would have  charged  for
         effecting  that  transaction,  if the  Management  Company  shall  have
         determined in good faith that the  commission is reasonable in relation
         to the value of the brokerage and research services provided,

<PAGE>

         viewed in terms of either that  particular  transaction  or the overall
         responsibilities of the Management Company with respect to all accounts
         as to which it now or hereafter exercises  investment  discretion.  For
         purposes of the immediately  preceding sentence,  "providing  brokerage
         and  research  services"  shall have the meaning  generally  given such
         terms  or  similar  terms  under  Section  28(e)(3)  of the  Securities
         Exchange Act of 1934, as amended.

    (d)  In the selection of a broker for the execution of any  transaction  not
         subject to fixed commission rates, the Management Company shall have no
         duty or  obligation  to seek advance  competitive  bidding for the most
         favorable   negotiated   commission  rate  to  be  applicable  to  such
         transaction,  or to  select  any  broker  solely  on the  basis  of its
         purported or "posted" commission rates.

    (e)  In  connection  with  transactions  on markets  other than  national or
         regional  securities  exchanges,  the Fund will deal  directly with the
         selling  principal or market maker  without  incurring  charges for the
         services of a broker on its behalf unless,  in the best judgment of the
         Management  Company,  better  price or  execution  can be  obtained  in
         utilizing the services of a broker.

4.  ALLOCATION  OF EXPENSES AND CHARGES.  The  Management  Company shall provide
    investment  advisory,  statistical and research  facilities and all clerical
    services  relating to research,  statistical and investment  work, and shall
    provide for the  compilation  and  maintenance  of such records  relating to
    these functions as shall be required under  applicable law and the rules and
    regulations  of the  Securities  and  Exchange  Commission.  Other  than  as
    specifically  indicated in the preceding  sentence,  the Management  Company
    shall not be required to pay any  expenses of the Fund,  and in  particular,
    but without limiting the generality of the foregoing, the Management Company
    shall  not be  required  to pay  office  rental  or  general  administrative
    expenses; board of directors' fees; legal, auditing and accounting expenses;
    insurance  premiums;  broker's  commissions;  taxes and  governmental  fees;
    membership dues; fees of custodian,  transfer agent,  registrar and dividend
    disbursing agent (if any);  expenses of obtaining  quotations on the Series'
    portfolio securities and pricing of the Series' shares;  expenses (including
    clerical  expenses)  of issue,  sale or  redemption  of shares of the Fund's
    capital stock;  costs and expenses in connection  with the  registration  of
    such  capital  stock  under  the 1933 Act and  qualification  of the  Fund's
    capital  stock  under the Blue Sky laws of the  states  where  such stock is
    offered;  costs and expenses in connection with the registration of the Fund
    under the 1940 Act and all periodic and other reports  required  thereunder;
    expenses of preparing reports, proxy statements, prospectuses and notices to
    stockholders and of printing and distributing reports, proxies, prospectuses
    and  notices  to  existing  stockholders;  costs  of  stationery;  costs  of
    stockholder and other meetings; expenses of maintaining the Fund's corporate
    existence;  and such nonrecurring expenses as may arise including litigation
    affecting the Fund and the legal  obligations the Fund may have to indemnify
    its officers and directors.

5.  COMPENSATION OF MANAGEMENT COMPANY.

    (a)  As compensation for the services rendered by the Management  Company as
         provided herein, for each of the years this agreement is in effect, the
         Fund shall pay the Management  Company an annual fee equal to 0.5 of 1%
         of the  average  daily  closing  value of the net assets of the Initial
         Series  computed  on a daily  basis.  Such fee  shall be  adjusted  and
         payable  monthly.  If this  Agreement  shall  be  effective  for only a
         portion of a year, then the Management Company's  compensation for said
         year shall be prorated for such  portion.  For purposes of this Section
         5, the value of the net assets of the Initial  Series shall be computed
         in the same manner on each  business  day as of the normal close of the
         New York Stock  Exchange as the value of such net assets is computed in
         connection with the  determination of the net asset value of the shares
         of the Initial Series as described in the Fund's prospectus.

    (b)  For  each of the  Fund's  full  fiscal  years  during  the term of this
         Agreement,  the Management Company guarantees that the aggregate annual
         expenses  of every  character,  exclusive  of  interest  and  taxes and
         extraordinary  expenses  (such as  litigation),  but  inclusive  of the
         Management  Company's  compensation,  incurred by the Series  shall not
         exceed an amount  equal to one percent of the average net assets of the
         Series for the year, such net assets to be calculated on a daily basis.
         The Management Company agrees, on a monthly basis, to contribute to the
         Fund such funds or to waive such portion of its fee as may be necessary
         to insure  that such  aggregate  annual  expenses  will not exceed said
         amount.  If this Agreement shall be effective for only a portion of one
         of the Fund's fiscal years,  then the maximum annual  expenses shall be
         prorated for such portion.  Brokerage fees and commissions  incurred in
         connection  with the  purchase  or sale of any  securities  by the Fund
         shall not be deemed to be expenses within the meaning of this Paragraph
         (b).

6.  MANAGEMENT  COMPANY  NOT TO  RECEIVE  COMMISSIONS.  In  connection  with the
    purchase  or sale of  portfolio  securities  for the  account  of the  Fund,
    neither the Management Company nor any officer or director of the Management
    Company  shall act as  principal or receive any  compensation  from the Fund
    other than its  compensation  as  provided  for in  Section 5 above.  If the
    Management Company, or any "affiliated person" (as defined in the Investment
    Company Act of 1940)  receives any cash credits,  commissions or tender fees
    from any person in connection with transactions in the portfolio  securities
    of the Fund  (including  but not  limited to the tender or  delivery  of any
    securities held in such portfolio), the Management Company shall immediately
    pay such  amount to the Fund in cash or as a credit  against any then earned
    but unpaid management fees due by the Fund to the Management Company.

<PAGE>

7.  LIMITATION OF LIABILITY OF  MANAGEMENT  COMPANY.  So long as the  Management
    Company  shall give the Fund the benefit of its best  judgment and effort in
    rendering services hereunder, the Management Company shall not be liable for
    any  errors of  judgment  or mistake of law,  or for any loss  sustained  by
    reason of the adoption of any  investment  policy or the  purchase,  sale or
    retention  of  any  security  on its  recommendation,  whether  or not  such
    recommendation shall have been based upon its own investigation and research
    or upon  investigation  and research made by any other  individual,  firm or
    corporation,  if such  recommendation  shall  have been made and such  other
    individual,  firm or corporation  shall have been selected with due care and
    in good faith.  Nothing herein  contained  shall,  however,  be construed to
    protect the  Management  Company  against any  liability  to the Fund or its
    contract  owners  by  reason  of  willful  misfeasance,  bad  faith or gross
    negligence  in the  performance  of its duties or by reason of its  reckless
    disregard of its  obligations  and duties under this  Agreement.  As used in
    this Section 7, "Management  Company" shall include directors,  officers and
    employees of the Management Company, as well as that corporation itself.

8.  OTHER ACTIVITIES NOT RESTRICTED. Nothing in this Agreement shall prevent the
    Management  Company or any officer thereof from acting as investment adviser
    for any other person, firm, or corporation, nor shall it in any way limit or
    restrict  the  Management  Company  or  any  of  its  directors,   officers,
    stockholders  or employees from buying,  selling,  or trading any securities
    for its own  accounts  or for the  accounts  of  others  for  whom it may be
    acting; provided,  however, that the Management Company expressly represents
    that it will undertake no activities  which, in its judgment,  will conflict
    with the  performance of its  obligations to the Fund under this  Agreement.
    The Fund acknowledges that the Management Company acts as investment adviser
    to other investment  companies,  and it expressly consents to the Management
    Company  acting as such;  provided,  however,  that if in the opinion of the
    Management Company, particular securities are consistent with the investment
    objectives  of, and desirable  purchases or sales for the portfolios of, one
    or more Series and one or more of such other investment  companies or series
    of such companies at  approximately  the same time,  such purchases or sales
    will be made on a proportionate basis if feasible, and if not feasible, then
    on a rotating or other equitable basis.

9.  DURATION AND TERMINATION OF AGREEMENT. This Agreement shall become effective
    on the  date  hereof,  provided  that on or  before  that  date it has  been
    approved by a majority of the holders of the outstanding  voting  securities
    of the Fund, and shall remain in force, unless sooner terminated as provided
    herein,  until the first regular or special meeting of the Fund stockholders
    following  the date shares of capital stock of the Fund are first offered to
    the public.  This Agreement  shall be presented to each Series of the Fund's
    stockholders at such meeting for their approval and shall continue in effect
    for successive 12-month periods, unless terminated,  provided that each such
    continuance is  specifically  approved at such meeting and at least annually
    thereafter by (a) the vote of a majority of the entire board of directors of
    the Fund, or, with respect to each Series,  by the vote of a majority of the
    outstanding  voting  securities  of such Series (as defined in the 1940 Act,
    and (b) the vote of a majority  of those  directors  who are not  parties to
    this  Agreement or  interested  persons (as such term is defined in the 1940
    Act) of any such party cast in person at a meeting

<PAGE>

    called for the  purpose of voting on such  approval.  In the event that this
    Agreement is approved by such vote of the outstanding  voting  securities of
    one or more  Series  but not of one or more  others,  this  Agreement  shall
    continue in effect with  respect to the former  Series and,  with respect to
    the latter may continue in effect until such  approval by the latter  Series
    of this Agreement or of a new agreement with the Management  Company or with
    another party is obtained,  provided that  compensation paid with respect to
    such  Series  pending  such  approval  is no greater  than the lesser of the
    Management  Company's  actual  costs  incurred  hereunder  or the amount due
    pursuant to Section 5 hereof.  This  Agreement may be terminated at any time
    without  payment of any penalty,  by the Fund upon the vote of a majority of
    the Fund's board of directors or, with respect to any Series,  by a majority
    of the outstanding  voting  securities of such Series,  or by the Management
    Company,  .in each  case on sixty  (60)  days'  written  notice to the other
    party.  This  Agreement  shall  automatically  terminate in the event of its
    assignment (as such term is defined in the 1940 Act).

IN WITNESS  WHEREOF,  the parties  hereto have caused this  Agreement to be duly
executed by their respective  corporate  officers thereto duly authorized on the
day, month and year first above written.

                    AMENDMENT TO INVESTMENT ADVISORY CONTRACT

WHEREAS,  Security  Tax-Exempt Fund (the "Fund") and Security Management Company
(the "Management  Company") are parties to an Investment Advisory Contract dated
October 7, 1983 (the "Agreement"),  under which the Management Company agrees to
provide  investment   research  and  advice  to  the  Fund  in  return  for  the
compensation specified in the Agreement;

WHEREAS,  effective  October  19,  1993,  the Fund will  offer its shares in two
Classes,  Class A shares,  which are currently  being offered,  and a new class,
Class B shares;

WHEREAS,  the Fund has adopted a  Distribution  Plan with respect to its Class B

WHEREAS,  the  distribution  fees  associated  with Class B shares  require  the
amendment of the Agreement relative to that class of shares;

WHEREAS,  on  October 1,  1993,  the  initial  Class B  shareholder  of the Fund
approved such amendment to this Agreement; and

WHEREAS,  the changes to the Agreement which are  contemplated by this Amendment
do not affect the interests of Class A shareholders of the Fund;

NOW, THEREFORE,  the Fund and the Management Company hereby amend the Investment
Advisory Contract, dated October 7, 1983, effective October 1, 1993, as follows:

A.  The Management Company agrees to provide investment  research and advice, to
    the Fund pursuant to the terms and conditions set forth in the Agreement, as
    amended in section B below.

B.  Section  5(b) of the  Agreement  shall  be  amended  by  deleting  it in its
    entirety and replacing it with the following:

    (b)  For  each of the  Fund's  full  fiscal  years  during  the term of this
         Agreement,  the Management Company guarantees that the aggregate annual
         expenses  of  every   character,   exclusive  of  interest  and  taxes,
         extraordinary expenses (such as litigation), and distribution fees paid
         under the  Fund's  Class B  Distribution  Plan,  but  inclusive  of the
         Management  Company's  compensation,  incurred  by the Fund  shall  not
         exceed an amount  equal to one percent of the average net assets of the
         Fund for the year,  such net assets to be  calculated on a daily basis.
         The Management Company agrees, on a monthly basis, to contribute to the
         Fund such funds or to waive such portion of its fee as may be necessary
         to insure  that such  aggregate  annual  expenses  will not exceed said
         amount.  If this Agreement shall be effective for only a portion of one
         of the Fund's fiscal years,  then the maximum annual  expenses shall be
         prorated for such portion.  Brokerage fees and commissions  incurred in

                             SUB-ADVISORY AGREEMENT


   THIS  AGREEMENT is made and entered  into on this ____ day of February,  1998
between  SECURITY  MANAGEMENT  COMPANY,  LLC (the  "Adviser"),  a Kansas limited
liability  company,  registered  under the  Investment  Advisers Act of 1940, as
amended (the  "Investment  Advisers Act"), and SALOMON BROTHERS ASSET MANAGEMENT
INC. (the "Subadviser"),  a New York corporation registered under the Investment
Advisers Act.

                                   WITNESSETH:

   WHEREAS,  Security  Tax-Exempt Fund (the "Fund"),  a Kansas  corporation,  is
registered with the Securities and Exchange  Commission (the "Commission") as an
open-end management investment company under the Investment Company Act of 1940,
as amended (the "Investment Company Act");

   WHEREAS,  the Fund has,  pursuant to an Advisory  Agreement  with the Adviser
(the "Advisory  Agreement"),  retained the Adviser to act as investment  adviser
for and to manage its assets;

   WHEREAS,  the Advisory  Agreement  permits the Adviser to delegate certain of
its duties under the Advisory Agreement to other investment advisers, subject to
the requirements of the Investment Company Act; and

   WHEREAS,  the Adviser  desires to retain the Subadviser as subadviser for the
Fund to act as investment  adviser for and to manage the Fund's  Investments (as
defined below) and the Subadviser desires to render such services.

   NOW,  THEREFORE,  the Adviser and Subadviser do mutually agree and promise as
follows:

   1.  APPOINTMENT AS  SUBADVISER.  The Adviser hereby retains the Subadviser to
act as investment  adviser for and to manage  certain assets of the Fund subject
to the  supervision  of the Adviser and the Board of  Directors  of the Fund and
subject to the terms of this Agreement;  and the Subadviser  hereby accepts such
employment. In such capacity, the Subadviser shall be responsible for the Fund's
Investments.

   2. DUTIES OF SUBADVISER.

      (a)  INVESTMENTS.  The  Subadviser is hereby  authorized  and directed and
   hereby agrees,  subject to the stated investment policies and restrictions of
   the  Fund  as set  forth  in  its  prospectus  and  statement  of  additional
   information as currently in effect and as  supplemented  or amended from time
   to time  (collectively  referred  to  hereinafter  as the  "Prospectus")  and
   subject to the  directions  of the Adviser and the Fund's  Board to purchase,
   hold  and  sell  investments  for  the  account  of  the  Fund   (hereinafter

<PAGE>

   "Investments")  and to monitor on a continuous  basis the performance of such
   Investments.  The  Subadviser  shall  give the Fund the  benefit  of its best
   efforts in rendering its services as Subadviser.  The Subadviser may contract
   with or consult with such banks,  other  securities  firms,  brokers or other
   parties,  without  additional expense to the Fund, as it may deem appropriate
   regarding   investment  advice,   research  and  statistical  data,  clerical
   assistance or otherwise.

      (b) BROKERAGE. The Subadviser is authorized, subject to the supervision of
   the Adviser and the Fund's Board to establish and maintain accounts on behalf
   of the Fund with,  and place  orders for the  purchase and sale of the Fund's
   Investments with or through,  such persons,  brokers or dealers as Subadviser
   may select and negotiate  commissions  to be paid on such  transactions.  The
   Subadviser agrees that in placing such orders it shall attempt to obtain best
   execution,  provided  that,  the  Subadviser  may, on behalf of the Fund, pay
   brokerage  commissions  to a broker  which  provides  brokerage  and research
   services to the  Subadviser in excess of the amount another broker would have
   charged for effecting the transaction, provided (i) the Subadviser determines
   in good faith that the amount is  reasonable  in relation to the value of the
   brokerage and research  services provided by the executing broker in terms of
   the  particular   transaction  or  in  terms  of  the  Subadviser's   overall
   responsibilities  with  respect to the Fund and the  accounts as to which the
   Subadviser  exercises  investment  discretion,  (ii) such  payment is made in
   compliance  with Section  28(e) of the  Securities  Exchange Act of 1934,  as
   amended,  and any other  applicable  laws and  regulations,  and (iii) in the
   opinion of the  Subadviser,  the total  commissions  paid by the Fund will be
   reasonable  in relation to the benefits to the Fund over the long term. It is
   recognized  that the  services  provided by such brokers may be useful to the
   Subadviser in connection with the Subadviser's  services to other clients. On
   occasions when the Subadviser  deems the purchase or sale of a security to be
   in the best  interests of a Fund as well as other clients of the  Subadviser,
   the Subadviser,  to the extent  permitted by applicable laws and regulations,
   may, but shall be under no obligation to, aggregate the securities to be sold
   or purchased in order to obtain the most favorable  price or lower  brokerage
   commissions and efficient execution.  In such event, allocation of securities
   so sold or purchased,  as well as the expenses  incurred in the  transaction,
   will be made by the Subadviser in the manner the  Subadviser  considers to be
   the most equitable and consistent with its fiduciary  obligations to the Fund
   and to such other clients.  The Subadviser will report on such allocations at
   the  request of the  Adviser,  the Fund or the Fund's  Board  providing  such
   information as the number of aggregated trades to which the Fund was a party,
   the  broker(s)  to whom  such  trades  were  directed  and the  basis  of the
   allocation for the aggregated trades.

      (c) SECURITIES  TRANSACTIONS.  The Subadviser and any affiliated person of
   the Subadviser will not purchase securities or other instruments from or sell
   securities  or  other  instruments  to  a  Fund  ("Principal  Transactions");
   PROVIDED, HOWEVER, the Subadviser may enter into a Principal Transaction with
   a Fund if (i) the  transaction  is  permissible  under  applicable  laws  and
   regulations,  including,  without limitation,  the Investment Company Act and
   the  Investment  Advisers  Act  and the  rules  and  regulations

                                       2
<PAGE>

   promulgated thereunder, and (ii) the transaction receives the express written
   approval of the Adviser.

          The Subadviser  agrees to observe and comply with Rule 17j-1 under the
   Investment  Company  Act and its Code of  Ethics,  as the same may be amended
   from time to time. The Subadviser  agrees to provide the Adviser and the Fund
   with a copy of such Code of Ethics.

      (d) BOOKS AND RECORDS.  The Subadviser will maintain all books and records
   required  to be  maintained  pursuant to the  Investment  Company Act and the
   rules and  regulations  promulgated  thereunder  with respect to transactions
   made by it on behalf of the Fund including, without limitation, the books and
   records required by Subsections (b)(1), (5), (6), (7), (9), (10) and (11) and
   Subsection  (f) of Rule  31a-1  under the  Investment  Company  Act and shall
   timely furnish to the Adviser all  information  relating to the  Subadviser's
   services hereunder needed by the Adviser to keep such other books and records
   of the Fund  required by Rule 31a-1 under the  Investment  Company  Act.  The
   Subadviser  will also  preserve  all such books and  records  for the periods
   prescribed  in Rule 31a-2 under the  Investment  Company Act, and agrees that
   such books and records  shall remain the sole  property of the Fund and shall
   be immediately  surrendered to the Fund upon request.  The Subadviser further
   agrees  that  all  books  and  records  maintained  hereunder  shall  be made
   available  to the Fund or the  Adviser at any time upon  reasonable  request,
   including telecopy, during any business day.

      (e) INFORMATION CONCERNING  INVESTMENTS AND SUBADVISER.  From time to time
   as the  Adviser or the Fund may  request,  the  Subadviser  will  furnish the
   requesting party reports on portfolio transactions and reports on Investments
   held in the  portfolio,  all in such  detail as the  Adviser  or the Fund may
   reasonably  request.  The  Subadviser  will make  available  its officers and
   employees to meet with the Fund's Board of Directors at the Fund's  principal
   place of business on due notice to review the Investments of the Fund.

          The  Subadviser  will also  provide such  information  or perform such
   additional  acts as are  customarily  performed  by a  subadviser  and may be
   required  for  the  Fund or the  Adviser  to  comply  with  their  respective
   obligations  under  applicable  laws,  including,   without  limitation,  the
   Internal  Revenue  Code of 1986,  as amended  (the  "Code"),  the  Investment
   Company Act, the  Investment  Advisers  Act, the  Securities  Act of 1933, as
   amended (the "Securities Act") and any state securities laws, and any rule or
   regulation thereunder.

      (f)  CUSTODY  ARRANGEMENTS.   The  Subadviser  shall  provide  the  Fund's
   custodian, on each business day with information relating to all transactions
   concerning the Fund's assets.

      (g)  COMPLIANCE  WITH  APPLICABLE  LAWS AND  GOVERNING  DOCUMENTS.  In all
   matters relating to the performance of this Agreement, the Subadviser and its
   directors,  officers, partners, employees and interested persons shall act in
   conformity with the

                                       3

   Fund's  Articles  of   Incorporation,   By-Laws,   and  currently   effective

   the  Investment  Company  Act, the  Investment  Advisers  Act, the  Commodity
   Exchange  Act, the rules  thereunder,  and all other  applicable  federal and
   state laws and regulations.

          In carrying out its obligations  under this Agreement,  the Subadviser
   shall  ensure  that  the  Fund  complies  with all  applicable  statutes  and
   regulations  necessary to qualify the Fund as a Regulated  Investment Company
   under Subchapter M of the Code (or any successor provision), and shall notify
   the Adviser immediately upon having a reasonable basis for believing that the
   Fund has ceased to so qualify or that it might not so qualify in the future.

          The Adviser has  furnished the  Subadviser  with copies of each of the
   following  documents and will furnish the Subadviser at its principal  office
   all future  amendments and supplements to such documents,  if any, as soon as
   practicable  after such  documents  become  available:  (i) the  Articles  of
   Incorporation  of the Fund, (ii) the By-Laws of the Fund and (iii) the Fund's

   to vote such proxies as may be necessary or advisable in connection  with any
   matters submitted to a vote of shareholders of securities held by the Fund.

   3. INDEPENDENT  CONTRACTOR.  In the performance of its duties hereunder,  the
Subadviser  is and  shall be an  independent  contractor  and  unless  otherwise
expressly  provided  herein or otherwise  authorized  in writing,  shall have no
authority  to act  for or  represent  the  Fund  or the  Adviser  in any  way or
otherwise be deemed an agent of the Fund or the Adviser.

rendered  hereunder,  an annual fee equal to 0.22  percent of the average  daily
closing  value of the net  assets of the  Fund,  computed  on a daily  basis and
payable  monthly.  If this Agreement  shall be effective for only a portion of a
year,  then the  Subadviser's  compensation  for said year shall be prorated for
such portion.  For purposes of this  paragraph 4, the value of the net assets of
the Fund shall be computed in the same manner at the end of the  business day as
the value of such net assets is computed in connection with the determination of
the net asset value of the Fund's shares as described in the Fund's  Prospectus.
Payment of the  Subadviser's  compensation for the preceding month shall be made
as promptly as possible after the end of each month.

   5.  EXPENSES.  The  Subadviser  shall  bear all  expenses  incurred  by it in

However,  the  Subadviser  shall not assign or delegate  any of its duties under

                             DISTRIBUTION AGREEMENT

   THIS  AGREEMENT,  made  this  7th  day of  October,  1983,  between  SECURITY
TAX-EXEMPT  FUND,  a  Kansas  corporation   (hereinafter   referred  to  as  the
"Company"),  and SECURITY DISTRIBUTORS,  INC., a Kansas corporation (hereinafter
referred to as the "Distributor"),

   WITNESSETH:

   WHEREAS,  the  Company is  engaged in  business  as an  open-end,  management
investment  company  registered  under the  Investment  Company Act of 1940 (the
"1940 Act"); and

   WHEREAS,  the  Company is  authorized  to issue  shares of  capital  stock in
separate  series,  with each such series  representing  interests  in a separate
portfolio of securities and other assets; and

   WHEREAS,  the Company  intends  initially to offer shares in one series to be
designated  Security Tax-Exempt Fund, such series together with all other series
subsequently  established  by the  Company  with  respect  to which the  Company
desires to retain the Distributor to render services  hereunder and with respect
to which the Distributor is willing so to do, being herein collectively referred
to as the "Series"; and

   WHEREAS,  the Distributor is willing to act as principal  underwriter for the
Company to offer for sale,  sell and deliver  after sale shares of the Company's
$.10 par value common  stock  (hereinafter  referred to as the  "Shares") on the
terms and conditions hereinafter set forth;

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

   1. EMPLOYMENT OF  DISTRIBUTOR.  The Company hereby employs the Distributor to
act as principal  underwriter  for the Company and hereby agrees that during the
term of this Agreement, and any renewal or extension thereof, or until any prior
termination thereof, the Distributor shall have the exclusive right to offer for
sale and to distribute  any and all Shares of each Series issued or to be issued
by the Company. The Distributor hereby accepts such employment and agrees to act
as the  distributor  of the Shares of each Series  issued or to be issues by the
Company  during the period this  Agreement  is in effect and agrees  during such
period to offer for sale such Shares as long as such Shares remain available for
sale,  unless the  Distributor  is unable legally to make such offer for sale as
the result of any law or governmental regulation.

   2. OFFERING PRICE AND COMMISSIONS. Prior to the issuance of any Shares by the
Company pursuant to any subscription  tendered by or through the Distributor and
confirmed for sale to or through the Distributor,  the Distributor  shall pay or
cause to be paid to the Custodian of the Company in cash, an amount equal to the
net asset value of such Shares at the time of

<PAGE>

acceptance of each such subscription and confirmation by the Company of the sale
of such Shares. The Distributor shall be entitled to charge a commission on each
such sale of Shares in the amount set forth in the  Company's  prospectus,  such
commission to be an amount equal to the  difference  between the net asset value
and the offering  price of the Shares,  as such offering  price may from time to
time be determined by the board of directors of the Company. All Shares shall be
sold to the public only at their public offering price at the time of such sale,
and the Company shall receive not less than the full net asset value thereof.

   3. ALLOCATION OF EXPENSES AND CHARGES. During the period this Agreement is in
effect,  the Company  shall pay all costs and  expenses in  connection  with its
registration  under the 1940 Act and the  registration  of its Shares  under the
Securities Act of 1933 ("1933 Act"),  including all expenses in connection  with
the preparation  and printing of any  registration  statements and  prospectuses
necessary for  registration  thereunder but excluding any  additional  costs and
expenses incurred in furnishing the Distributor with  prospectuses.  The Company
shall also pay all costs,  expenses  and fees  incurred in  connection  with the
qualification  of the Shares under the applicable Blue Sky laws of the states in
which the Shares are offered.

   During the period this  Agreement  is in effect the  Distributor  will pay or
reimburse the Company for:

   (a) All costs and expenses of printing and mailing  prospectuses  (other than
for existing  shareholders) and confirmations (except for reinvested dividends),
and all costs and  expenses  of  preparing,  printing  and  mailing  advertising
material, sales literature, circulars, applications, and other materials used or
to be used in connection with the offering for sale and the sale of Shares; and

   (b) All clerical and administrative  costs in processing the applications for
and in connection with the sale of Shares.

   The  Distributor  agrees to submit to the Company for its prior  approval all
advertising material,  sales literature,  circulars and any other material which
the  Distributor  proposes to use in  connection  with the  offering for sale of
Shares.

   4. DISTRIBUTOR MAY ACT AS BROKER AND RECEIVE COMMISSIONS. Notwithstanding any
other  provisions  of this  Agreement,  it is  understood  and  agreed  that the
Distributor may act as a broker,  on behalf of the Company,  in the purchase and
sale of securities not effected on a securities exchange, provided that any such
transactions  and any commission  paid in connection  therewith  shall comply in
every  respect  with the  requirements  of the 1940 Act and in  particular  with
Section 17(e) of that Act and the Rules and  Regulations  of the  Securities and
Exchange Commission promulgated thereunder.

   5. AGREEMENTS  SUBJECT TO APPLICABLE LAW AND REGULATIONS.  The parties hereto
agree  that  all  provisions  of this  Agreement  will be  performed  in  strict
accordance  with  the  requirements  of the  1940  Act,  the  1933  Act  and the
Securities Exchange Act of 1934, and the rules and regulations of the Securities
and Exchange  Commission  under said  statutes,  in strict  accordance

                                      -2-
<PAGE>

with  all  applicable  state  Blue  Sky  laws  and  the  rules  and  regulations
thereunder,  and in strict  accordance  with the  provisions  of the Articles of
Incorporation and Bylaws of the Company.

   6.  DURATION  AND  TERMINATION  OF  AGREEMENT.  This  Agreement  shall become
effective at the date and time that the  Company's  prospectus,  reflecting  the
underwriting  arrangements  provided by this Agreement,  shall become  effective
under the 1933 Act, and shall, unless terminated as provided herein, continue in
force for two years from that date, and from year to year  thereafter,  provided
that such  continuance  for each  successive  year is  specifically  approved in
advance at least  annually by either the board of  directors or by the vote of a
majority (as defined in the 1940 Act) of the  outstanding  voting  securities of
the Company and, in either event,  by the vote of a majority of the directors of
the Company who are not parties to this  Agreement or interested  persons of any
such  party,  cast in person at a meeting  called for the purpose of voting upon
such approval. As used in the preceding sentence, the words "interested persons"
shall have the  meaning set forth in Section  2(a)(19) of the 1940 Act.  Written
notice of any such  approval  by the board of  directors  or by the holders of a
majority of the outstanding  voting  securities of the Company and the directors
who are not such interested persons shall be given promptly to the Distributor.

   This  Agreement  may be  terminated  at any time  without  the payment of any
penalty  by the  Company  by giving  the  Distributor  at least  sixty (60) days
previous  written notice of such  intention to terminate.  This Agreement may be
terminated by the  Distributor  at any time by giving the Company at least sixty
(60) days previous written notice of such intention to terminate.

   This Agreement shall terminate  automatically in the event of its assignment.
As used in the preceding sentence,  the word "assignment" shall have the meaning
set forth in Section 2(a)(4) of the 1940 Act.

   7.  CONSTRUCTION OF AGREEMENT.  No provision of this Agreement is intended to
or shall be construed as protecting the Distributor against any liability to the
Company or to the  Company's  security  holders to which the  Distributor  would
otherwise  be  subject  by reason  of  willful  misfeasance,  bad faith or gross
negligence in the performance of its duties under this Agreement.

   Terms or words used in this  Agreement,  which also occur in the  Articles of
Incorporation  or Bylaws of the Company,  shall have the same meaning  herein as
given to such terms or words in the Articles of  Incorporation  or Bylaws of the
Company.

   8. DISTRIBUTOR AN INDEPENDENT CONTRACTOR.  The Distributor shall be deemed to
be an independent  contractor and, except as expressly provided or authorized by
the Company, shall have no authority to act for or represent the Company.

   9. NOTICE.  Any notice  required or permitted to be given hereunder to either
of the parties  hereto shall be deemed to have been given if mailed by certified
mail in a postage prepaid envelope addressed to the respective party as follows,
unless  any such  party  has  notified  the  other

                                      -3-

<PAGE>

          (v)    Any fees paid by the Distributor to securities dealers who
                 have executed a Dealer's  Distribution  Agreement with the
                 Distributor for account  maintenance and personal  service
                 to shareholders of the Fund (a "Service Fee");

          (vi)   Commissions  to sales  personnel for selling shares of the
                 Fund and interest expenses related thereto; and

          (vii)  Expenses incurred in promoting sales of shares of the Fund

                 entertainment,  and other expenses  incurred in connection
                 with promoting sales of the Fund shares by dealers.

     (b)  All payments to the  Distributor  pursuant to this  paragraph are
          subject to the following conditions being met by the Distributor.
          The  Distributor  shall furnish the Fund with  quarterly  written
          reports of its expenditures and such other  information  relating
          to expenditures or to the other  distribution-related  activities
          undertaken or proposed to be undertaken by the Distributor during
          such fiscal year under its  Distribution  Agreement with the Fund
          as the Fund may reasonably request;

     (c)  The   Dealer's    Distribution    Agreement   (the   "Agreement")
          contemplated by paragraph 5A(a)(v) above shall permit payments to
          securities dealers by the Distributor only in accordance with the
          provisions  of this  paragraph and shall have the approval of the
          majority  of the  Board of  Directors  of the Fund,  including  a
          majority of the directors who are not  interested  persons of the
          Fund,  as required by the Rule.  The  Distributor  may pay to the
          other party to any  Dealer's  Distribution  Agreement a quarterly
          fee for  distribution  and  marketing  services  provided by such
          other party. Such quarterly fee shall be payable in arrears in an
          amount  equal to such  percentage  (not in excess of .000685% per
          day) of the  aggregate  net asset value of the Fund's shares held
          by such  other  party's  customers  or  clients  at the  close of
          business  each  day  as  determined  from  time  to  time  by the
          Distributor. The distribution and marketing services contemplated
          hereby shall include, but are not limited to, answering inquiries
          regarding  the  Fund,   account   designations   and   addresses,
          maintaining  the  investment of such other  party's  customers or
          clients in the Fund and  similar  services.  In  determining  the
          extent of such  other  party's  assistance  in  maintaining  such
          investment by its customers or clients,  the Distributor may take
          into  account  the  possibility  that  the  shares  held  by such
          customer  or client  would be  redeemed  in the  absence  of such
          quarterly fee.

<PAGE>

     (d)  The provisions of the Distribution  Plan approved by the Board of
          Directors of the Fund on February 6, 1998, are fully incorporated
          herein by reference.  In the event the Class A Distribution  Plan
          is not approved by a majority vote of Class A shareholders of the
          Fund at the Fund's special  meeting to be held April 24, 1998, or
          is terminated  by the Board of Directors or Class A  shareholders
          of the Fund as provided  therein,  this paragraph shall no longer
          be effective.

The Fund and  Distributor  hereby  further  amend  the  Distribution  Agreement,
effective  May 1,  1998,  by  deleting  the  second  paragraph  of Section 6 and
replacing it with the following.

     This  Agreement may be terminated at any time,  without the payment of
     any  penalty,  by vote of a majority of the board of  directors of the
     Company  who are not  interested  persons of the  Company  and have no
     direct or indirect  financial interest in the operation of the Class A
     Distribution  Plan or in this  Distribution  Agreement or by vote of a
     majority of the outstanding  Class A voting  securities of the Company
     on sixty (60) day's written notice to the Distributor.  This Agreement
     may be terminated by the Distributor at any time by giving the Company
     sixty  (60)  days'  previous  written  notice  of  such  intention  to
     terminate.

IN WITNESS  WHEREOF,  the parties  hereto have  executed  this  Amendment to the
Distribution Agreement this _____ day of ____________________, 1998.

                             DISTRIBUTION AGREEMENT

THIS AGREEMENT,  made this 1st day of October 1993, between Security  Tax-Exempt
Fund,  a Kansas  corporation  (hereinafter  referred to as the  "Company"),  and
Security  Distributors,  Inc., a Kansas corporation  (hereinafter referred to as
the "Distributor").

                                   WITNESSETH:

WHEREAS,  the  Company  is  engaged  in  business  as  an  open-end,  management
investment  company  registered under the federal Investment Company Act of 1940
(the "1940 Act"); and

WHEREAS,  the  Distributor  is willing to act as principal  underwriter  for the
Company to offer for sale,  sell and deliver  after sale,  the Class B Shares of
the  Company's  $.10 par value  common  stock  (hereinafter  referred  to as the
"Shares") on the terms and conditions hereinafter set forth;

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

 1.  EMPLOYMENT OF  DISTRIBUTOR.  The Company hereby employs the  Distributor to
     act as  principal  underwriter  for the Company with respect to its Class B
     Shares and hereby  agrees that during the term of this  Agreement,  and any
     renewal or extension thereof, or until any prior termination  thereof,  the
     Distributor  shall  have  the  exclusive  right  to  offer  for sale and to
     distribute  any and all of its Class B Shares issued or to be issued by the
     Company.  The Distributor  hereby accepts such employment and agrees to act
     as the  distributor  of the  Class B Shares  issued  or to be issued by the
     Company  during the period this  Agreement  is in effect and agrees  during
     such  period to offer for sale such  Shares as long as such  Shares  remain
     available for sale,  unless the  Distributor is unable legally to make such
     offer for sale as the result of any law or governmental regulation.

 2.  OFFERING PRICE AND COMMISSIONS.  Prior to the issuance of any Shares by the
     Company pursuant to any subscription tendered by or through the Distributor
     and confirmed for sale to or through the Distributor, the Distributor shall
     pay or cause to be paid to the  custodian of the Company in cash, an amount
     equal to the net asset  value of such Shares at the time of  acceptance  of
     each such  subscription and confirmation by the Company of the sale of such
     Shares.  All  Shares  shall  be sold to the  public  only at  their  public
     offering  price at the time of such sale, and the Company shall receive not
     less than the full net asset value thereof.

 3.  ALLOCATION OF EXPENSES AND CHARGES.  During the period this Agreement is in
     effect, the Company shall pay all costs and expenses in connection with the
     registration  of Shares under the  Securities Act of 1933 (the "1933 Act"),
     including all expenses in connection  with the  preparation and printing of
     any  registration  statements and  prospectuses  necessary for registration
     thereunder  but excluding  any  additional  costs and expenses  incurred in
     furnishing the Distributor with prospectuses.

                                      -1-

The Company will also pay all costs,  expenses and fees  incurred in  connection
with the  qualification  of the Shares under the applicable Blue Sky laws of the
states in which the Shares are offered.

During the period  this  Agreement  is in effect,  the  Distributor  will pay or
reimburse the Company for:

     (a)  All costs and  expenses of printing  and mailing  prospectuses  (other
          than to existing  shareholders) and  confirmations,  and all costs and
          expenses of  preparing,  printing  and mailing  advertising  material,
          sales literature, circulars, applications, and other materials used or
          to be used in  connection  with the  offering for sale and the sale of
          Shares; and

     (b)  All clerical and  administrative  costs in processing the applications
          for and in connection with the sale of Shares.

The  Distributor  agrees to submit to the  Company  for its prior  approval  all
advertising material,  sales literature,  circulars and any other material which
the  Distributor  proposes to use in  connection  with the  offering for sale of
Shares.

 4.  REDEMPTION OF SHARES.  The Distributor,  as agent of and for the account of
     the Fund, may redeem Shares of the Fund offered for resale to it at the net
     asset value of such  Shares  (determined  as  provided  in the  Articles of
     Incorporation  or Bylaws) and not in excess of such maximum  amounts as may
     be fixed from time to time by an officer of the Fund. Whenever the officers
     of the Fund deem it advisable for the protection of the shareholders of the
     Fund, they may suspend or cancel such authority.

 5.  SALES CHARGES. A contingent  deferred sales charge shall be retained by the
     Distributor  from the net  asset  value of  Shares  of the Fund that it has
     redeemed,  it being  understood  that such amounts will not be in excess of
     that set  forth in the  then-current  registration  statement  of the Fund.
     Furthermore,  the Distributor may retain any amounts authorized for payment
     to it under the Fund's Distribution Plan.

 6.  DISTRIBUTOR MAY ACT AS BROKER AND RECEIVE COMMISSIONS.  Notwithstanding any
     other  provisions of this  Agreement,  it is understood and agreed that the
     Distributor may act as a broker, on behalf of the Company,  in the purchase
     and sale of securities not effected on a securities exchange, provided that
     any such transactions and any commission paid in connection therewith shall
     comply  in  every  respect  with  the  requirements  of the 1940 Act and in
     particular  with Section 17(e) of that Act and the rules and regulations of

     herein,  continue  in force for two years from that date,  and from year to

     would otherwise be subject by reason of willful  misfeasance,  bad faith or
     gross negligence in the performance of its duties under this Agreement.

                                DISTRIBUTION PLAN

1.  THE PLAN. This Distribution Plan (the "Plan"), provides for the financing by
    Security  Tax-Exempt  Fund (the "Fund") of  activities  which are, or may be
    deemed to be, primarily  intended to result in the sale of class A shares of
    the  Fund  (hereinafter  called  "distribution-related   activities").   The
    principal  purpose  of  this  Plan  is to  enable  the  Fund  to  supplement
    expenditures by Security  Distributors,  Inc., the Distributor of its shares
    (the  "Distributor")  for  distribution-related  activities.  This  Plan  is
    intended to comply with the  requirements  of Rule 12b-1 (the "Rule")  under
    the Investment Company Act of 1940 (the "1940 Act").

    The Board of Directors, in considering whether the Fund should implement the
    Plan, has requested and evaluated such information as it deemed necessary to
    make an informed  determination as to whether the Plan should be implemented
    and has considered such pertinent factors as it deemed necessary to form the
    basis for a decision to use assets of the Fund for such purposes.

    In voting to approve the  implementation  of the Plan,  the  Directors  have
    concluded,  in the  exercise of their  reasonable  business  judgment and in
    light of their  respective  fiduciary  duties,  that  there is a  reasonable
    likelihood that the Plan will benefit the Fund and its shareholders.

2.  COVERED EXPENSES.

    (a)  The Fund may make payments  under this Plan, or any agreement  relating
         to the  implementation  of this Plan, in connection with any activities
         or expenses  primarily intended to result in the sale of class A shares
         of  the  Fund,   including,   but  not   limited   to,  the   following
         distribution-related activities:

         (i)    Preparation,  printing and  distribution  of the  Prospectus and
                Statement of Additional  Information and any supplement  thereto
                used in connection with the offering of the Fund's shares to the
                public;

         (ii)   Printing  of  additional  copies for use by the  Distributor  as
                sales literature, of reports and other communications which were
                prepared by the Fund for distribution to existing shareholders;

         (iii)  Preparation,  printing  and  distribution  of  any  other  sales
                literature  used in  connection  with the offering of the Fund's
                shares to the public;

         (iv)   Expenses  incurred in advertising,  promoting and selling shares
                of the Fund to the public;

<PAGE>

         (v)    Any fees paid by the Distributor to securities  dealers who have
                executed a Dealer's Distribution  Agreement with the Distributor
                for account  maintenance and personal service to shareholders of
                the Fund (a "Service Fee");

         (vi)   Commissions  to sales  personnel for selling  shares of the Fund
                and interest expenses related thereto; and

         (vii)  Expenses  incurred in  promoting  sales of shares of the Fund by
                securities  dealers,  including  the  costs  of  preparation  of
                materials  for   presentations,   travel   expenses,   costs  of
                entertainment,  and other expenses  incurred in connection  with
                promoting sales of Fund shares by dealers.

    (b)  Any payments for distribution-related activities shall be made pursuant
         to an agreement.  As required by the Rule,  each agreement  relating to
         the  implementation  of this Plan  shall be in writing  and  subject to
         approval and  termination  pursuant to the  provisions  of Section 7 of
         this Plan. However,  this Plan shall not obligate the Fund or any other
         party to enter into such agreement.

3.  AGREEMENT WITH DISTRIBUTOR. All payments to the Distributor pursuant to this
    Plan shall be subject to and be made in compliance with a written  agreement
    between  the  Fund  and the  Distributor  containing  a  provision  that the
    Distributor  shall furnish the Fund with  quarterly  written  reports of the
    amounts expended and the purposes for which such expenditures were made, and
    such  other  information  relating  to  such  expenditures  or to the  other
    distribution-related  activities  undertaken or proposed to be undertaken by
    the  Distributor  during such fiscal year under its  Distribution  Agreement
    with the Fund as the Fund may reasonably request.

4.  DEALER'S DISTRIBUTION  AGREEMENT.  The Dealer's Distribution  Agreement (the
    "Agreement")  contemplated  by Section 2(a)(v) above shall permit payment of
    Service Fees to  securities  dealers by the  Distributor  only in accordance
    with the  provisions  of this  paragraph  and shall have the approval of the
    majority of the Board of Directors of the Fund,  including  the  affirmative
    vote of a majority of those Directors who are not interested  persons of the
    Fund and who have no direct or indirect  financial interest in the operation
    of the Plan or any agreement related to the Plan ("Independent  Directors"),
    as required by the Rule. The  Distributor  may pay to the other party to any
    such  Agreement  a  Service  Fee for  distribution  and  marketing  services
    provided by such other party.  Such Service Fee shall be payable (a) for the
    first year,  initially,  in an amount  equal to .25 percent  annually of the
    aggregate  net asset  value of the shares  purchased  by such other  party's
    customers  or  clients,  and (b) for each  year  thereafter,  quarterly,  in
    arrears  in an amount  equal to such  percentage  (not in excess of  .000685
    percent per day or .25 percent annually) of the aggregate net asset value of
    the shares held by such other  party's  customers or clients at the close of
    business each day as determined  from time to time by the  Distributor.  The
    distribution and marketing services  contemplated hereby shall include,  but
    are  not  limited  to,  answering  inquiries  regarding  the  Fund,  account
    designations and addresses, maintaining the investment of such other party's
    customers or clients in the Fund and similar  services.  In

<PAGE>

    determining the extent of such other party's  assistance in maintaining such
    investment  by its  customers  or  clients,  the  Distributor  may take into
    account  the  possibility  that the shares  held by such  customer or client
    would be redeemed in the absence of such fee.

5.  LIMITATIONS  ON  COVERED  EXPENSES.  The basic  limitation  on the  expenses
    incurred by the Fund under Section 2 of this Plan  (including  Service Fees)
    in any fiscal year of the Fund shall be one-quarter of one percent (.25%) of
    the Fund's average daily net assets for such fiscal year. The payments to be
    paid  pursuant to this Plan shall be  calculated  and accrued daily and paid
    monthly or at such other intervals as the Directors shall determine, subject
    to any applicable  restriction imposed by rules of the National  Association
    of Securities Dealers, Inc.

6.  INDEPENDENT  DIRECTORS.  While this Plan is in  effect,  the  selection  and
    nomination  of  Independent  Directors of the Fund shall be committed to the
    discretion of the  Independent  Directors.  Nothing herein shall prevent the
    involvement of others in such selection and nomination if the final decision
    on any such  selection  and  nomination  is  approved  by a majority  of the
    Independent Directors.

7.  EFFECTIVENESS,  CONTINUATION,  TERMINATION AND AMENDMENT. This Plan and each
    Agreement  relating to the  implementation of this Plan shall go into effect
    when approved.

    (a)  By vote of the Fund's  Directors,  including the affirmative  vote of a
         majority  of the  Independent  Directors,  cast in  person at a meeting
         called for the purpose of voting on the Plan or the Agreement;

    (b)  By a vote of holders of at least a majority of the  outstanding  voting
         securities of the Class A shares of the Fund; and

    (c)  Upon the  effectiveness  of an  amendment  to the  Fund's  registration
         statement, reflecting this Plan, filed with the Securities and Exchange
         Commission under the Securities Act of 1933.

    This Plan and any  Agreements  relating to the  implementation  of this Plan
    shall,  unless terminated as hereinafter  provided,  continue in effect from
    year to year only so long as such  continuance is  specifically  approved at
    least annually by vote of the Fund's  Directors,  including the  affirmative
    vote of a majority of its Independent Directors, cast in person at a meeting
    called  for the  purpose  of voting on such  continuance.  This Plan and any
    Agreements relating to the implementation of this Plan may be terminated, in
    the case of the Plan, at any time or, in the case of any agreements upon not
    more  than  sixty  (60)  days'  written  notice  to any  other  party to the
    Agreement by vote of a majority of the Independent  Directors or by the vote
    of the holders of a majority of the  outstanding  voting  securities  of the
    Class A shares of the Fund. Any Agreement  relating to the implementation of
    this Plan shall  terminate  automatically  in the event it is assigned.  Any
    material amendment to this Plan shall require approval by vote of the Fund's
    Directors,  including the affirmative  vote of a majority of the Independent
    Directors,  cast in person at a meeting  called for the

<PAGE>

    purpose  of voting  on such  amendment  and,  if such  amendment  materially
    increases the limitations on expenses  payable under the Plan, it shall also
    require  approval  by a vote  of  holders  of at  least  a  majority  of the
    outstanding  voting securities of the Class A shares of the Fund. As applied
    to the Class A shares of the Fund the phrase  "majority  of the  outstanding
    voting  securities"  shall have the meaning specified in Section 2(a) of the
    1940 Act.

    In the event this Plan should be terminated by the shareholders or Directors
    of the Fund, the payments paid to the Distributor pursuant to the Plan up to
    the date of termination  shall be retained by the Distributor.  Any expenses
    incurred by the  Distributor  in excess of those  payments  will be the sole
    responsibility of the Distributor.

8.  RECORDS.  The Fund  shall  preserve  copies  of this  Plan  and any  related
    Agreements  and all reports made pursuant to Section 3 hereof,  for a period
    of not less than six (6)  years  from the date of this  Plan,  the first two
    years in an easily accessible place.
