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
18.

     The investment objective of SECURITY TAX-EXEMPT FUND ("Tax-Exempt Fund") is
to obtain as high a level of interest income exempt from 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,  including
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.

</TABLE>

(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 21.

(3)  During the fiscal year ended  December 31,  1996,  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, 1997 will waive the investment  advisory fees of Limited Maturity Bond,
     U.S. Government and High Yield 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,  1996,  the  Investment  Manager
     reimbursed certain expenses of the Funds. Absent such reimbursement, "Other
     Expenses" would have been as follows:  .53% for Class B shares of Corporate
     Bond Fund;  1.06% for Class B shares of Limited  Maturity Bond Fund;  1.73%
     for Class B shares of U.S.  Government Fund; and .68% for Class B shares of
     Tax-Exempt Fund.

(6)  During the fiscal year ended  December 31,  1996,  the  Investment  Manager
     waived  and/or  reimbursed  certain  expenses of the Funds and,  during the
     fiscal year ending  December  31, 1997 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: 2.05% for Class B shares of Corporate Bond Fund; 1.40% for
     Class A shares and 2.60% for Class B shares of Limited  Maturity Bond Fund;
     1.17%  for Class A shares  and 3.26% for Class B shares of U.S.  Government
     Fund;  2.11% for Class A shares  and 2.83% for Class B shares of High Yield
     Fund; and 2.19% for Class B shares of Tax-Exempt 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,  Tax-Exempt 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 19.
Information on the Funds' 12b-1 Plans may be found under the headings  "Security
Income Fund's Class A  Distribution  Plan" on page 22 and "Class B  Distribution
Plan" on page 23. See "How to Purchase  Shares,"  page 20, 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 purchase of Class A Shares.

INVESTMENT OBJECTIVES AND POLICIES OF THE FUNDS

     Security  Income,  Tax-Exempt  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  Tax-Exempt  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 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 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 Fund 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.

     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."

     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, 1996, 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, 1996. 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 interest  payments at a deferred date. See "Investment  Methods and Risk
Factors" for a discussion of zero coupon securities.

     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. See "Investment Methods and Risk Factors."

     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 period August 5, 1996 (date of inception) to December 31, 1996, the

The foregoing  table is intended solely to provide  disclosure  about High Yield
Fund's asset  composition  for the period  August 5, 1996 (date of inception) to
December  31,  1996.  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.
Government Securities."

     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 TAX-EXEMPT FUND

     The investment objective of Tax-Exempt Fund is to obtain as high a level of
interest  income  exempt  from  federal  income  taxes  as  is  consistent  with
preservation of stockholders'  capital.  Tax-Exempt Fund attempts to achieve its
objective by investing  primarily in debt  securities,  the interest on which is
exempt from federal income taxes,  including the alternative  minimum tax. Under
normal  circumstances,  at least 80 percent  of the  Fund's  net assets  will be
invested in such tax-exempt securities.

     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"  and are  described  in  more  detail  in the  Funds'  Statement  of
Additional Information.

     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) or S&P (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,
Tax-Exempt  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.  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,  the
Investment  Manager 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.

     Tax-Exempt  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.  Tax-Exempt 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  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,  Tax-Exempt  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 Tax-Exempt 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 or Prime-1 by
Moody's,  corporate  obligations rated AAA or AA by S&P 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.

     Tax-exempt interest on private activity bonds and exempt-interest dividends
attributable  to private  activity bonds generally are treated as tax preference
items for purposes of the alternative minimum tax. The Fund may purchase private
activity bonds, such as industrial  development  bonds, when other bonds are not
available and when the yield  differential  between  private  activity bonds and
other municipal bonds justifies their purchase.

     From time to time,  Tax-Exempt 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.

     Tax-Exempt 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  Tax-Exempt 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.

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.

     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.

debt securities  (debt securities rated Baa by Moody's or BBB 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.  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.
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 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
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.

     SOVEREIGN  DEBT.  Certain  of  the  Funds  may  invest  in  sovereign  debt
securities of emerging market governments,  including Brady Bonds, provided they
are denominated in

SECURITY FUNDS
PROSPECTUS
- --------------------------------------------------------------------------------

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 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 (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,  Tax-Exempt 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 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 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.

     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

                                       17

SECURITY FUNDS
PROSPECTUS
- --------------------------------------------------------------------------------

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

                                       18
<PAGE>

SECURITY FUNDS
PROSPECTUS
- --------------------------------------------------------------------------------

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 mutual life insurance company with over $15.5 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 $3.5 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.  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  Tax-Exempt  and Cash  Funds  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  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, Tax-Exempt
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
Tax-Exempt  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.

     For the year ended December 31, 1996, the total  expenses,  as a percentage
of average net assets,  were 1.01 percent for Class A and 1.85 percent for Class
B shares of  Corporate  Bond Fund;  .65 percent for Class A and 1.86 percent for
Class B shares of U.S. Government Fund; .90 percent for Class A and 1.88 percent
for Class B shares of Limited  Maturity  Bond Fund;  .78 percent for Class A and
2.01 percent for Class B shares of  Tax-Exempt  Fund;  and 1.01 percent for Cash
Fund.  For the period  August 5, 1996 (date of  inception) to December 31, 1996,
the total  expenses  were 1.54  percent for Class A shares and 2.26  percent for
Class B shares of High Yield Fund.

offering made by this prospectus and to reject purchase orders.

     As a convenience to investors and to save operating expenses,  the Funds do
not issue  certificates  for Fund  shares  except  upon  written  request by the
stockholder.

CORPORATE  BOND,  LIMITED  MATURITY  BOND,  U.S.  GOVERNMENT,   HIGH  YIELD  AND
TAX-EXEMPT FUNDS

     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 Tax-Exempt 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  Tax-Exempt  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
Tax-Exempt  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 37 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.

CLASS A SHARES

     Class A shares of Corporate Bond,  Limited Maturity Bond, U.S.  Government,
High Yield and  Tax-Exempt  Funds are offered at net asset value plus an initial

     Purchases of Class A shares of the Corporate Bond,  Limited  Maturity Bond,
U.S.  Government,  High Yield and  Tax-Exempt  Funds in amounts of $1,000,000 or
more are made at net asset value (without a sales charge),  but are subject to a
contingent  deferred  sales  charge of one  percent  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"
on page 23.

     The  Distributor  will pay a  commission  to dealers on such  purchases  of
$1,000,000 or more as follows: 1.00 percent on sales up to $5,000,000,  plus .50
percent on sales of $5,000,000 or more up to $10,000,000  and .10 percent 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 Tax-Exempt  Fund

and certain other Security Funds during prior periods and certain other factors,
including  providing  certain  services to their clients who are stockholders of
such Funds.  Such services  include  assisting  stockholders in changing account
options  or  enrolling  in  specific  plans,  and  providing  stockholders  with
information regarding the Funds and related developments.

     Currently,  service fees are paid on the aggregate value of accounts opened
after July 31, 1990, in Security Tax-Exempt,  Equity, Asset Allocation,  Global,
Social  Awareness,  Value,  Ultra and Growth and Income  Funds at the  following
annual  rates:  .25 percent of aggregate net asset value for amounts of $100,000
but less than $5 million and .30 percent for amounts of $5,000,000 or more.

SECURITY INCOME FUND'S CLASS A DISTRIBUTION PLAN

     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 and
High Yield 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. This 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 the 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 and High Yield 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.

     The 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 Fund's 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  and High Yield  Funds.  Other  promotional  activities  which may be
financed  pursuant to the Plan  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 and High Yield
Funds' Class A  Distribution  Plan may be  terminated at any time by vote of the
directors of Income 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  Plan is  terminated  by the Funds'  Class A
stockholders  or the 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.

CLASS B SHARES

     Class B shares of Corporate Bond,  Limited Maturity Bond, U.S.  Government,
High  Yield and  Tax-Exempt  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 Tax-Exempt 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 30 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 Tax-Exempt  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 Tax-Exempt  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.

    (c)  For initial investment,  send a completed investment application to the

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 Tax-Exempt 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  Tax-Exempt  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
Tax-Exempt Funds, respectively, for the fiscal year ended December 31, 1996, was
as  follows:  Corporate  Bond  Fund - 292  percent;  U.S.  Government  Fund - 75
percent;  Limited  Maturity Bond Fund - 105 percent;  and  Tax-Exempt  Fund - 54
percent.  The annualized portfolio turnover rate for the High Yield Fund for the
period August 5, 1996 (date of inception) to December 31, 1996, was 168 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.

SECURITY FUNDS
PROSPECTUS
- --------------------------------------------------------------------------------

     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 26.

DIVIDENDS AND TAXES

     It is the policy of Corporate Bond, Limited Maturity Bond, U.S. Government,
High Yield and  Tax-Exempt  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 Tax-Exempt 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  Tax-Exempt  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.

     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  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.

     Tax-Exempt  Fund intends to qualify to pay "exempt  interest  dividends" to
its stockholders.  Tax-Exempt 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  Tax-Exempt  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."

     To the extent that Tax-Exempt 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 Tax-Exempt 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  Tax-Exempt  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 (designated by Corporate
Bond,  Limited  Maturity Bond, U.S.  Government and High Yield Funds as "capital
gain dividends") of the excess,  if any, of net long-term capital gains over net
short-term  capital losses are taxable to stockholders as long-term capital gain
regardless of how long a stockholder  has held the Fund's shares and  regardless
of whether received in cash or reinvested in additional 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,  1996,   Corporate  Bond,  Limited  Maturity  Bond,  U.S.
Government,  High Yield and Tax-Exempt Funds, respectively,  had accumulated net
realized losses on sales of investments in the following  amounts:  $12,356,928,
$69,564, $978,377, $36,585 and $1,477,887.

     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.

While stockholders of the Funds will indirectly bear the cost of any foreign tax
withholding,  they will not be able to claim foreign tax credit or deduction for
taxes paid by the Funds.

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 Tax-Exempt  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 Tax-Exempt  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 Tax-Exempt  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
Tax-Exempt  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 Tax-Exempt Fund
and "average  annual total  return" and  "aggregate  total return" for Corporate
Bond, Limited Maturity Bond, U.S. Government, High Yield and Tax-Exempt 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 Tax-Exempt  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.

     Tax-Exempt 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 Tax-Exempt  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 Tax-Exempt 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  Tax-Exempt  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 Tax-Exempt  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 Tax-Exempt 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 23.  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, Tax-Exempt,  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,
Tax-Exempt,  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 Tax-Exempt  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.

     Tax-Exempt 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
outstanding shares.

     Although  each Fund  offers only its own  shares,  it is possible  one Fund
might become liable for any misstatement, inaccuracy or incomplete disclosure in
this prospectus  relating to another of the Funds. The Board of Directors of the
Funds  has  considered  this  risk  and  has  approved  the  use  of a  combined
prospectus.

STOCKHOLDER INQUIRIES

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

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 and Standard &
Poor's applicable to permitted investments of Tax-Exempt 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.

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.

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 Tax-Exempt 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  Tax-Exempt  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,  Tax-Exempt,  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 Tax-Exempt  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 Tax-Exempt 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  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.   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 44.)

     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,  Security  Tax-Exempt  Fund  ("Tax-Exempt  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 25. 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
47.)

     The shares of Corporate Bond, Limited Maturity Bond, U.S. Government,  High
Yield and  Tax-Exempt  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 31.)

     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  Tax-Exempt  and Cash Funds  exceed 1% of the  average net assets of the
Fund for the year.  (See page 38 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 and High Yield 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 and High Yield Funds to finance
various  distribution-related  activities.  (See "Security Income Fund's Class A
Distribution Plan," page 33.)

     Under  Distribution  Plans  adopted  with  respect to the Class B shares of
Corporate  Bond,  Limited  Maturity  Bond,  U.S.  Government,   High  Yield  and
Tax-Exempt  Funds  pursuant  to Rule  12b-1  under  the 1940  Act,  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
34.)

                                       1
<PAGE>

     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 of Corporate Bond, U.S. Government,  Limited Maturity Bond and Tax-Exempt
Funds for the fiscal year ended December 31, 1996,  was:  Corporate Bond - 292%;
U.S.  Government - 75%;  Limited  Maturity Bond -105%; and Tax-Exempt - 54%. The
portfolio  turnover rate for the Funds' Class A and B shares for the fiscal year
ended December 31, 1995 was:  Corporate Bond - 200%; U.S.  Government - 81%; and
Tax-Exempt - 103%. 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%. The annualized portfolio turnover rate for the Class
A and B shares of Limited  Maturity  Bond Fund for the period  January  17, 1995
(date of  inception)  to  December  31, 1995 was 4%.  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  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

                                       2
<PAGE>

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
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

                                       3
<PAGE>

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.

     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

                                        4
<PAGE>

"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.  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"

                                       5
<PAGE>

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 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

                                       6
<PAGE>

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
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

                                       7
<PAGE>

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 TAX-EXEMPT FUND

     The investment objective of Tax-Exempt Fund is to obtain as high a level of
interest  income  exempt  from  federal  income  taxes  as  is  consistent  with
preservation of stockholders'  capital.  Tax-Exempt Fund attempts to achieve its
objective by investing  primarily in debt  securities,  the interest on which is
exempt from federal  income taxes under the Internal  Revenue Code including the
alternative  minimum tax. There is no assurance that Tax-Exempt 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  Tax-Exempt  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.

     Tax-Exempt  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) or S&P (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,  Tax-Exempt  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 Tax-Exempt  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. 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  characteristics  and in fact
have  speculative  characteristics  as well." The  ratings  of  Moody's  and S&P
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.

                                       8
<PAGE>

     Although   Tax-Exempt  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,  Tax-Exempt  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 Tax-Exempt 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 or Prime-1 by
Moody's,  corporate  obligations rated AAA or AA by S&P 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.  Tax-Exempt  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.

     Tax-Exempt Fund may invest in repurchase agreements which are agreements by
which a purchaser (e.g., Tax-Exempt 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.  Tax-Exempt 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."

     Tax-Exempt  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.

     See Appendix B to the prospectus  for a further  description of Moody's and
S&P ratings relating to municipal securities.  As noted earlier, when Tax-Exempt
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.  Industrial development
bonds which pay  tax-exempt  interest are in most cases revenue bonds and do not
generally  carry the  pledge of the full  faith and credit of the issuer of such
bonds. The payment of the principal and interest on

                                       9
<PAGE>

such industrial  development  bonds depends solely on the ability of the user of
the facilities  financed by the bonds to meet its financial  obligations and the
pledge,  if any, of real and personal  property so financed as security for such
payment.  Tax-Exempt  Fund will not  invest  more  than 5% of its net  assets in
securities  where  the  principal  and  interest  are the  responsibility  of an
industrial  user  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 Tax-Exempt 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.

     Tax-Exempt  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,  Tax-Exempt 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  25.)  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.  Tax-Exempt
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  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 Tax-Exempt
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,  Tax-Exempt 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.  Tax-Exempt 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.
Tax-Exempt  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

                                       10
<PAGE>

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.  Tax-Exempt 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. Tax-Exempt 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 Tax-Exempt  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  Tax-Exempt  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  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 Tax-Exempt Fund.

     Tax-Exempt   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

                                       11
<PAGE>

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 Tax-Exempt Fund will
limit its investments to "high quality"  short-term  securities.  For short-term
municipal notes this includes  ratings of AA or better by S&P or MIG 2 or better
by Moody's; for municipal paper this includes A-2 or better by S&P or Prime-2 or
better by Moody's.  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 Tax-Exempt 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.

     Tax-Exempt  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  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

                                       12
<PAGE>

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
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

                                       13
<PAGE>

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 47.)

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 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.

                                       14
<PAGE>

     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,  Tax-Exempt 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 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

                                       15
<PAGE>

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 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

                                       16
<PAGE>

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
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

                                       17
<PAGE>

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 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

                                       18
<PAGE>

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.

     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.

                                       19
<PAGE>

     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.

     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

                                       20
<PAGE>

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  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

                                       21
<PAGE>

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.

     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.

                                       22
<PAGE>

     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.

     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 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

                                       24
<PAGE>

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  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.

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

                                       26
<PAGE>

      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.

TAX-EXEMPT FUND'S FUNDAMENTAL POLICIES

     Tax-Exempt 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;

 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;

 8.   Not to invest more than 5% of its total  assets in  securities  of any one
      issuer, except securities issued or guaranteed 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

                                       27
<PAGE>

      "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 12;

 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;

 3.   Not to pledge its assets or  otherwise  encumber  them in excess of 10% of
      its net assets  (taken at market value at the time of  pledging)  and then
      only to secure  borrowings  effected  within the  limitations set forth in
      restriction 2;

 4.   Not to make loans of money or  securities,  except (a) by the  purchase of
      debt  obligations  in  which  the  Fund  may  invest  consistent  with its
      investment  objectives  and policies or (b) by  investment  in  repurchase
      agreements,  subject to limitations  described under "Security Cash Fund,"
      page 12;

 5.   Not to invest in the securities of an issuer if the officers and directors
      of the Fund 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;

 6.   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 the  securities  of any one issuer (other than
      obligations issued or guaranteed by the U.S.  Government,  its agencies or
      instrumentalities);

 7.   Not to purchase  more than 10% of any class of  securities  of any issuer.
      (For purposes of this restriction,  all outstanding debt securities of any
      issuer are considered one class.)

 8.   Not to invest more than 25% of the market or other fair value of its total
      assets in the securities of issuers,  all of which conduct their principal
      business   activities  in  the  same  industry.   (For  purposes  of  this
      restriction,  utilities will be divided  according to their services;  for
      example,  gas, gas transmission,  electric,  water and telephone utilities
      will each be treated as being a separate  industry.  This restriction does
      not apply to  investment  in bank  obligations  or  obligations  issued or
      guaranteed   by  the  United   States   Government   or  its  agencies  or
      instrumentalities.)

 9.   Not to purchase  securities on margin,  except for such short-term credits
      as are  necessary  for the  clearance of purchases  and sales of portfolio
      securities;

10.   Not to invest  more than 5% of the market or other fair value of its total
      assets  in  securities  of  companies  having  a  record,   together  with
      predecessors,  of less than three  years of  continuous  operation.  (This
      restriction  shall  not  apply to banks or any  obligation  of the  United
      States Government, its agencies or instrumentalities.)

11.   Not to engage in the underwriting of securities except insofar as the Fund
      may be deemed an underwriter under the Securities Act of 1933 in disposing
      of a portfolio security;

12.   Not to make short sales of securities;

13.   Not to purchase or sell real estate,  although it may purchase  securities
      of issuers which engage in real estate  operations,  securities  which are
      secured by interests in real estate, or securities  representing interests
      in real estate;

                                       28
<PAGE>

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

15.   Not to purchase  oil,  gas or other  mineral  leases,  rights,  or royalty
      contracts or exploration or development programs, except that the Fund may
      invest in the  securities  of  companies  which  invest in or sponsor such
      programs;

16.   Not to  purchase  securities  of other  investment  companies,  except  in
      connection with a merger, consolidation,  reorganization or acquisition of
      assets;

17.   Not to write, purchase or sell puts, calls, or combinations thereof;

18.   Not to purchase or sell commodities or commodity futures contracts;

19.   Not to issue senior securities as defined in the Investment Company Act of
      1940.

     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
immediately after, and is caused by, an acquisition or disposition of securities
or utilization of assets by Cash Fund.

Corporate  Bond,  Limited  Maturity  Bond,  U.S.  Government,   High  Yield  and

Cash Fund's  officers and  directors  (as a group)  beneficially  owned  528,589
shares which represented approximately 1.057% of the total outstanding shares on

HOW TO PURCHASE SHARES

     As discussed below,  shares of Corporate Bond,  Limited Maturity Bond, U.S.
Government,  High Yield and  Tax-Exempt  Funds may be  purchased  with  either a
front-end or contingent  deferred sales charge.  Shares of Cash Fund are offered
by the Fund  without a sales  charge.  Each of the Funds  reserves  the right to
withdraw all or any part of the offering made by this  prospectus  and to reject
purchase orders.

     As a convenience to investors and to save operating expenses,  the Funds do
not issue  certificates  for Fund  shares  except  upon  written  request by the
stockholder.

CORPORATE  BOND,  LIMITED  MATURITY  BOND,  U.S.  GOVERNMENT,   HIGH  YIELD  AND
TAX-EXEMPT 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 Tax-Exempt 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

                                       31
<PAGE>

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
Tax-Exempt  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.

CLASS A SHARES

     Class A shares of Corporate Bond,  Limited Maturity Bond, U.S.  Government,
High Yield and  Tax-Exempt  Funds are offered at net asset value plus an initial
sales charge as follows:

     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 35. 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 Tax-Exempt  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 FUND'S CLASS A DISTRIBUTION PLAN

     As discussed in the prospectus,  each of Corporate Bond,  Limited  Maturity
Bond, U.S. Government and High Yield Funds has a Distribution Plan for its Class
A shares  pursuant to Rule 12b-1 under the  Investment  Company Act of 1940. The
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.

     The Plan  became  effective  on August  15,  1985,  and was  renewed by the
directors of Income Fund on February 7, 1997,  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 7, 1997.  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 7, 1997.
The 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 Class A  shareholders  vote to
terminate the Plan.  Any agreement  relating to the  implementation  of the Plan
terminates  automatically  if it is  assigned.  The Plan 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 Pantages (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 and High Yield 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,  1996,  totaled  $248,326.  In  addition,
$96,790 was carried forward from the previous plan year.  Approximately $177,429
of this  amount was paid as a service fee to  broker/dealers  and  $171,996  was
spent on  promotions,  resulting in a deficit of $4,309 going into the 1997 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

                                       33
<PAGE>

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  Tax-Exempt  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
Tax-Exempt  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.
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 Tax-Exempt  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 Tax-Exempt  Funds on July 23, 1993 and was renewed on
February 7, 1997.  The Plan was adopted  with respect to Limited  Maturity  Bond
Fund on October  21,  1994 and was  renewed on  February  7, 1997.  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 7, 1997.  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

                                       34
<PAGE>

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 Tax-Exempt Funds to the
Distributor  under  the Plan for the  year  ended  December  31,  1996,  totaled
$91,597.  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 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

                                       35
<PAGE>

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:

                                       36
<PAGE>

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)  Wire federal funds to:                    Bank IV of Topeka
                                          Attention Security Distributors, Inc.
                                                   Topeka, Kansas 66603

         Include investor's name and the account number.

    (c)  For initial investment,  send a completed investment application to the
         Fund at the above address.

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  Tax-Exempt  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.

     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  Tax-Exempt  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.

                                       37
<PAGE>

ACCUMULATION PLAN

     Investors in Corporate Bond, Limited Maturity Bond, U.S.  Government,  High
Yield or  Tax-Exempt  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 Tax-Exempt
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 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.

INVESTMENT MANAGEMENT

     Security Management Company, LLC (the "Investment  Manager"),  700 Harrison
Street,  Topeka,  Kansas,  has  served as  investment  adviser  to Income  Fund,
Tax-Exempt Fund and Cash Fund,  respectively,  since September 14, 1970, October
7, 1983 and June 23, 1980. The current Investment  Advisory Contracts for Income
Fund,  Tax-Exempt  Fund and Cash Fund,  respectively,  are dated March 27, 1987,
October 7, 1983 and June 23,  1980,  and were  renewed  by the  Funds'  Board of
Directors at a regular  meeting held February 7, 1997.  The  Investment  Manager
also acts as investment  adviser to Security  Equity Fund,  Security  Growth and
Income  Fund,  Security  Ultra Fund and SBL Fund.  The  Investment  Manager is a
limited  liability  company  controlled  by its

                                       38
<PAGE>

members,  Security  Benefit Life Insurance  Company and Security  Benefit Group,
Inc.  ("SBG").  SBG is an  insurance  and  financial  services  holding  company
wholly-owned by Security  Benefit Life Insurance  Company,  700 Harrison Street,
Topeka,  Kansas  66636-0001.  Security  Benefit  Life,  a mutual life  insurance
company with over $15.5 billion of insurance in force, is incorporated under the
laws of Kansas.

     Pursuant to the  Investment  Advisory  Contracts,  the  Investment  Manager
furnishes investment  advisory,  statistical and research services to the Funds,
supervises and arranges for the purchase and sale of securities on behalf of the
Funds, provides for the maintenance and compilation of records pertaining to the
investment advisory functions, and also makes certain guarantees with respect to
the Funds' annual expenses. The Investment Manager guarantees that the aggregate
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 Corporate
Bond,  Limited  Maturity Bond,  U.S.  Government and High Yield Funds exceed the
level of expenses which the 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 and shall not for  Tax-Exempt and Cash Funds exceed 1% of the
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 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.

     For  its  services,   the   Investment   Manager  is  entitled  to  receive
compensation  on an annual basis equal to .5% of the average daily closing value
of the Corporate Bond,  Limited Maturity Bond, U.S.  Government,  Tax-Exempt and
Cash Fund's net assets and .60% of the average  daily  closing value of the High
Yield Fund,  each  computed on a daily  basis and  payable  monthly.  During the
fiscal  years  ended  December  31,  1996,  1995 and 1994,  the  Funds  paid the
following amounts to the Investment  Manager for its services:  1996 - $534,366;
1995 - $549,076;  and 1994 - $560,388 for Income Fund;  1996 - $120,946;  1995 -
$128,492;  and 1994 - $146,469 for Tax-Exempt Fund; and 1996 - $247,304;  1995 -
$254,139;  and 1994 - $285,251 for Cash Fund.  For the years ended  December 31,
1996,  1995 and 1994, the Investment  Manager agreed to limit the total expenses
(including its  compensation,  but excluding  interest,  taxes and extraordinary
expenses and Class B distribution  fees) of Corporate  Bond and U.S.  Government
Funds  to  1.1%  of the  average  daily  net  assets  of the  respective  Funds.
Accordingly,  the Investment Manager reimbursed the U.S.  Government Fund in the
following  amounts:  1996 -  $60,974;  1995 - $16,803;  and 1994 - $11,684;  and
Corporate Bond Fund: 1996 - $10,663;  1995 - $15,121; and 1994 - $4,276. For the
year ended December 31, 1995,  expenses incurred by Cash Fund exceeded 1% of the
average net assets and accordingly,  the Investment Manager reimbursed Cash Fund
in the amount of $12,968.  For the years ended December 31, 1996, 1995 and 1994,
expenses  incurred by Tax-Exempt  Fund exceeded 1% of the average net assets and
accordingly,  the Investment Manager  reimbursed  Tax-Exempt Fund 1996 - $2,358;
1995 - $4,504;  and 1994 - $1,505. The Investment Manager agreed to waive all of
the management fees for the Limited  Maturity Bond Fund through July 1, 1995. In
addition, the Investment Manager agreed to waive the investment advisory fees of
Limited Maturity Bond, U.S.  Government and High Yield Funds for the fiscal year
ended December 31, 1996.

     Each  Fund  will pay all of its  expenses  not  assumed  by the  Investment
Manager or the Distributor  including  organization  expenses;  directors' fees;
fees and expenses of custodian;  taxes and governmental fees;  interest charges;
membership dues;  brokerage  commissions;  reports;  proxy statements;  costs of
stockholder and other meetings;  Class B distribution fees; 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 federal and state securities laws. Each
Fund will pay nonrecurring expenses as may arise, including litigation affecting
it.

     The Investment Advisory Contracts between Security Management Company,  LLC
and Income Fund, Tax-Exempt Fund and Cash Fund, dated March 27, 1987, October 7,
1983 and June 23, 1980,  respectively,  expire on April 1, 1998, May 1, 1998 and
June 1, 1998.  The  contracts  are  renewable  annually  by the Funds'  Board of
Directors or by a vote of a majority of a Fund's outstanding  securities and, in
either event,  by a majority of the board who are not parties to the contract or
interested  persons of any such party.  The  contracts  provide that they may be
terminated  without  penalty at any time by either  party on 60 days' notice and
are automatically terminated in the event of assignment.

     Pursuant to Administrative  Services  Agreements with the Funds dated April
1, 1987, the Investment  Manager also acts as the  administrative  agent for the
Funds  and as  such  performs  administrative  functions  and  the

                                       39

bookkeeping,  accounting and pricing functions for the Funds. For these services
the  Investment  Manager  receives,  on an  annual  basis,  a fee of .09% of the
average net assets of Corporate Bond,  Limited  Maturity Bond, U.S.  Government,
High  Yield and  Tax-Exempt  Funds and .045% of the  average  net assets of Cash
Fund,  calculated  daily and  payable  monthly.  During the fiscal  years  ended
December  31,  1996,  1995 and 1994,  the Funds paid the  following  amounts for
administrative services: 1996 - $95,487; 1995 - $98,667; and 1994 - $100,870 for
Income Fund; 1996 - $22,530;  1995 - $23,129;  and 1994 - $26,364 for Tax-Exempt
Fund; and 1996 - $21,721; 1995 - $22,898; and 1994 - $25,703 for Cash Fund.

     Under  the  Administrative   Services  Agreements   identified  above,  the
Investment  Manager also acts as the transfer agent for the Funds.  As such, the
Investment  Manager  performs all  shareholder  servicing  functions,  including
transferring record ownership,  processing purchase and redemption transactions,
answering  inquiries,  mailing  stockholder  communications  and  acting  as the
dividend  disbursing agent. For these services,  the Investment Manager receives
an annual  maintenance fee of $8.00 per account,  a fee of $1.00 per shareholder
transaction,  and a fee of $1.00 ($.50 for Cash Fund) per dividend  transaction.
During the fiscal years ended December 31, 1996,  1995, and 1994, the Funds paid
the following  amounts for transfer  agency  services:  1996 - $128,776;  1995 -
$127,227;  and 1994 - $122,198 for Income Fund; 1996 - $16,538;  1995 - $16,716;
1994 - $18,811 for Tax-Exempt  Fund; and 1996 - $130,682;  1995 - $152,798;  and
1994 - $139,429 for Cash Fund.

     The total  expenses of the Corporate  Bond,  Limited  Maturity  Bond,  U.S.
Government,  High  Yield,  Tax-Exempt  and Cash Funds for the fiscal  year ended
December  31, 1996 were  $936,593;  $52,769;  $75,838;  $40,482;  $208,821;  and
$482,615;  respectively.  The  expense  ratio for fiscal year 1996 was 1.01% and
1.85%,  respectively  of the  average  net assets of Class A and B shares of the
Corporate Bond Fund and .90% and 1.88%, respectively,  of the average net assets
of Class A and Class B shares of Limited  Maturity Bond Fund.  The expense ratio
for the fiscal year 1996 was .65% and 1.86%, respectively,  of the net assets of
Class A and Class B shares  of U.S.  Government  Fund and .78%,  2.01% and 1.01%
respectively,  of the  average  net  assets of the Class A and Class B shares of
Tax-Exempt  Fund and Cash Fund.  The expense  figures  quoted are net of expense
reimbursements  and by fees  paid  indirectly  as a result of  earnings  credits
earned on  overnight  cash  balances.  For the  period  August 5, 1996  (date of
inception) to December 31, 1996 the expense ratios were 1.54% for Class A shares
and 2.26% for Class B shares of High Yield Fund, respectively.

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 Tax-Exempt 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 LS Variable  Annuity,  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.

                                       41
<PAGE>

     The Distributor received gross underwriting commissions on sales of Class A
shares and contingent  deferred sales charges on redemptions  for Class B shares
of $132,788  for Income Fund and $42,066 for  Tax-Exempt  Fund and  retained net
underwriting  commissions  of $39,452 for Income Fund and $13,059 for Tax-Exempt
Fund for the fiscal year ended December 31, 1996. The Distributor received gross
underwriting  commissions on sales of Class A shares of $80,868 and $244,043 for
Income  Fund and  $20,691  and $64,008  for  Tax-Exempt  Fund and  retained  net
underwriting  commissions  of $9,910 and  $48,307 for Income Fund and $4,103 and
$13,009 for  Tax-Exempt  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

                                       42
<PAGE>

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 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, 1996, 1995 and 1994.

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, 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  Tax-Exempt
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 Tax-Exempt 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.   Tax-Exempt  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

                                       43
<PAGE>

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.

     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 47. 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  Tax-Exempt  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  Tax-Exempt  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.

                                       44
<PAGE>

     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 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 54.)

     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.

     Tax-Exempt  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.

                                       45

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 44.

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

                                       46
<PAGE>

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 47.)
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

     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,  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) derive in each taxable year less than 30% of its gross income from the sale
or other  disposition  of certain assets held less than three months (namely (a)
stock or  securities,  (b) options,  futures and forward  contracts  (other than
those on foreign  currencies),  and (c) foreign currencies  (including  options,
futures,  and forward  contracts on such  currencies) not directly  related to a
Fund's  principal  business of investing in stocks or securities (or options and
futures with respect to stocks and securities)); (iii) 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

                                       47
<PAGE>

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  (iv)  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  Tax-Exempt  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 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.

                                       48
<PAGE>

     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  Tax-Exempt  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.

     Stockholders will report as long-term capital gains income any realized net
long-term  capital  gains in  excess  of any  capital  loss  carryover  which is
distributed  to them,  and  designated  by the Fund as a capital  gain  dividend
whether received in cash or reinvested in additional  shares,  and regardless of
the period of time such shares have been owned by the stockholder.  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.

     Tax-Exempt  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 Tax-Exempt 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. Tax-Exempt Fund will
inform stockholders annually as to the portion of that year's distributions from
the Fund which constituted "exempt-interest dividends."

     To the extent that  Tax-Exempt  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 Tax-Exempt 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 long-term capital gain or
loss if the shares  have been held for more than one year.  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.

                                       49

     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  Tax-Exempt  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 Tax-Exempt  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 Tax-Exempt 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.

     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.

                                       50

     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.

     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.

     ORIGINAL ISSUE DISCOUNT.  Debt securities purchased by a Fund (such as zero
coupon  bonds) may be treated  for U.S.  federal  income tax  purposes as having
original  issue  discount.  Original  issue  discount is treated as interest for
federal  income tax purposes  and can  generally be defined as the excess of the
stated  redemption  price at  maturity  over the  issue  price.  Original  issue
discount,  whether or not cash  payments  actually  are  received by a Fund,  is
treated  for  federal  income tax  purposes  as income  earned by the Fund,  and
therefore is subject to the  distribution  requirements of the Code.  Generally,
the amount of original  issue  discount  included in the income of the Fund each
year is determined on the basis of a constant yield to maturity which takes into
account the compounding of accrued interest.

     In addition, debt securities may be purchased by a Fund at a discount which
exceeds the original issue discount remaining on the securities,  if any, at the
time the Fund purchased the  securities.  This  additional  discount  represents
market  discount for income tax purposes.  Treatment of market  discount  varies
depending upon the maturity of the debt security.  Generally, in the case of any
debt security  having a fixed  maturity date of more than one year from the date
of issue and having market  discount,  the gain realized on disposition  will be
treated as ordinary  income to the extent it does not exceed the accrued  market
discount on the  security  (unless  the Fund elects for all its debt  securities
having a fixed  maturity  date of more  than one year  from the date of issue to
include  market  discount  in income in tax years to which it is  attributable).
Generally,  market  discount  accrues on a daily  basis.  For any debt  security
having a fixed  maturity  date of not more than one year from the date of issue,
special  rules  apply  which  may  require  in some  circumstances  the  ratable
inclusion of income  attributable  to discount at which the bond was acquired as
calculated  under the Code.  A Fund may be required to  capitalize,  rather than
deduct currently, part or all of any net direct interest expense on indebtedness
incurred  or  continued  to purchase or carry any debt  security  having  market
discount  (unless  the Fund  makes  the  election  to  include  market  discount
currently).

     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  Tax-Exempt
Fund shares.  (See "Municipal  Securities," page 9.) 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 Tax-Exempt  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.  Tax-Exempt and Cash Funds have not
issued shares in any
                                       51
<PAGE>

additional series at the present time. Tax-Exempt 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 Tax-Exempt  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,  Tax-Exempt 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.

     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,  Tax-Exempt 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  Tax-Exempt  Fund and  average  annual  total  return  and
aggregate total return for Tax-Exempt 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, 1996 was
4.80%.

     Cash Fund's  effective (or  compound)  yield for the same period was 4.92%.
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 Tax-Exempt  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:

                                       52
<PAGE>

                         YIELD = 2[(A-B + 1)6 - 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.

     Tax-Exempt  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, 1996,  the yield for the Class A
shares of the  following  Funds was 6.30% for  Corporate  Bond  Fund,  5.56% for
Limited Maturity Bond Fund,  6.05% for the U.S.  Government Fund, 7.10% for High
Yield  Fund,  and  4.74%  for  Tax-Exempt  Fund.  For the same  period,  the tax
equivalent yield for the Class A shares of Tax-Exempt Fund assuming a 15% income
tax rate and a 28% income tax rate, respectively, was 5.58% and 6.58%.

     For the 30-day  period ended  December 31, 1996,  the yield for the Class B
shares of the following  Funds was 5.59% for the Corporate Bond Fund,  5.55% for
Limited Maturity Bond Fund,  4.96% for the U.S.  Government Fund, 6.68% for High
Yield  Fund,  and  3.19%  for  Tax-Exempt  Fund.  For the same  period,  the tax
equivalent yield for the Class B shares of Tax-Exempt Fund assuming a 15% income
tax rate and a 28% income tax rate, respectively, was 3.75% and 4.43%.

     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 Tax-Exempt Fund over periods of 1, 5 and 10 years (up to the life of the
Fund), calculated pursuant to the following formula:

                                 P(1+T)n = 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, 1996,  the average
annual total return for Class A shares of the U.S.  Government  Fund was -3.59%,
5.19% and 7.10%,  respectively.  For the 1-year period ended  December 31, 1996,
the average annual total return for Class B shares of U.S.  Government  Fund was
- -4.97%.  For the period  October 19, 1993 (date of  inception)  to December  31,
1996, the average annual total return for Class B shares of the U.S.  Government
Fund was 1.95%.

     For the 1-, 5- and 10-year  periods  ended  December 31, 1996,  the average
annual total return for Class A shares of Tax-Exempt Fund was -2.40%,  4.50% and
5.33%, respectively.  For the 1-year period ended December 31, 1996, the average
annual total return for Class B shares of  Tax-Exempt  Fund was -3.76%.  For the
period  October 19, 1993 (date of inception)  to December 31, 1996,  the average
annual total return for Class B shares of Tax-Exempt Fund was 0.27%.

     For the 1-year  period ended  December 31, 1996,  the average  annual total
return  for Class A and B shares of  Limited  Maturity  Bond Fund was -2.74% and
- -3.95%,  respectively.  For the period  January 17, 1995 (date of  inception) to
December 31, 1996,  the average  annual total return for Class A and B shares of
Limited Maturity Bond Fund was 4.94% and 4.68%, respectively.

                                       53
<PAGE>

     For the period August 5, 1996 (date of inception) to December 31, 1996, the
average annual total return for Class A and B shares of High Yield Fund was .23%
and -.24%, respectively.

     The aggregate  total return for Income and  Tax-Exempt  Funds is calculated
for any specified period of time pursuant to the following formula:

                                 P(1+T)n = 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 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 Tax-Exempt Fund calculated as
described  above for the period from December 31, 1986,  for the Corporate  Bond
Fund, U.S.  Government Fund and Tax-Exempt  Fund,  through December 31, 1996 was
92.0%,  98.5% and 68.0%,  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 Tax-Exempt Fund calculated as
described  above for the period  October 19, 1993 through  December 31, 1996 was
- -0.9%,  6.4% and 0.9%,  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, 1996 was 9.9% and 9.3%, 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,  1996,  was .10% and -.10%,  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.

                                       54
<PAGE>

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.

     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 Tax-Exempt Fund's investment objective
is to  obtain  a high  level of  interest  income  exempt  from  federal  taxes,
Tax-Exempt 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 an IRA each  year of up to the
lesser of $2,000 or 100% of earned  income under  current tax law.  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 an 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.

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

                                       55
<PAGE>

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

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.

                                    APPENDIX A

CLASS A SHARES OF CORPORATE BOND, LIMITED MATURITY BOND, U.S. GOVERNMENT, HIGH 
YIELD AND TAX-EXEMPT 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 Tax-Exempt 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  Tax-Exempt  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,
Tax-Exempt  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 Tax-Exempt 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,  Tax-Exempt 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 Tax-Exempt
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.
