THE FUND

WHO MAY INVEST -- The Fund is designed for investors  seeking  preservation  and
stability of principal  and a level of current  income  higher than money market
mutual funds over most time periods.  The Fund has been  established to serve as
an alternative  investment to short-term  bond funds and money market funds.  In
addition,  the Fund is designed as a  comparable  investment  to stable value or
guaranteed  investment  contract options offered in employee benefit plans (such
as 401(k) plans).  The Fund currently offers three classes of shares exclusively
to TSA  Accounts,  individual  retirement  accounts and to  employees  investing
through participant-directed  employee benefit plans (each a "Plan" and together
"Plans").  For the purpose of this prospectus,  individual  retirement  accounts
include,  but are  not  limited  to,  those  accounts  commonly  referred  to as
traditional IRAs, Roth IRAs, simplified employee pension IRAs ("SEP-IRAs"), IRAs
that are part of a savings  incentive match plan for employees  ("SIMPLE IRAs"),
Keogh plans and education IRAs (each, an "IRA," collectively  referred to herein
as "IRAs").  See  "Overview of the Types of Individual  Retirement  Accounts" on
page 32. The Fund is offering the Shares to owners of TSA  Accounts,  IRAs (each
an "IRA Owner") and participants of Plans who purchase Shares through their Plan
("Plan  Participants").  Shares  are  available  to TSA  Accounts  or IRA Owners
directly  through a  Security  Funds TSA or IRA or  through  another  TSA or IRA
provider who makes available Shares of the Fund.

    Shares are offered to Plans either  directly,  or through  vehicles  such as
bank collective funds or insurance company separate  accounts  consisting solely
of such Plans.  Shares are also available to employee benefit plans which invest
in the Fund through an omnibus account or similar arrangement.

    The  Fund  is not in  itself  a  balanced  investment  plan.  Owners  of TSA
Accounts, IRA Owners and Plan Participants (collectively, "Shareholders") should
consider  their  investment  objectives  and  tolerance  for risk when making an
investment  decision.  When Shares are redeemed,  they may be worth more or less
than  what  they  originally  cost,  although  the  nature  of  the  Portfolio's
investments--particularly   the  Wrapper  Agreements  (as  defined   below)--are
intended to stabilize the Fund's NAV per Share.

INVESTMENT OBJECTIVE

The Fund's  investment  objective is to provide  investors  with a high level of
current income while seeking to maintain a stable NAV per Share.  The Fund seeks
to  achieve  its  investment  objective  by  investing  all of its Assets in the
Portfolio.  The Portfolio  will seek to achieve this objective by investing in a
diversified  portfolio of fixed  income  securities,  money market  instruments,
futures,  options and other instruments ("Portfolio Securities") and by entering
into wrapper agreements with financial institutions, such as insurance companies
and banks,  which are intended to  stabilize  the NAV per Share of the Fund (the
"Wrapper Agreements"). See "Overview of Wrapper Agreements and Associated Risks"
herein.  In  connection  with the Global Asset  Allocation  Strategy  (described
below),  Portfolio Securities may include indexed securities,  futures contracts
on securities  indices,  securities  representing  securities of foreign issuers
(e.g.  ADRs, GDRs and EDRs),  options on stocks,  options on futures  contracts,
foreign currency exchange  transactions and options on foreign  currencies.  See
"Investment  Objectives  and  Policies -- Global Asset  Allocation  Enhancement"
herein.  There  can be no  assurance  that  the Fund  will  achieve  its  stated
investment objective.

EXPENSE SUMMARY

Annual  operating  expenses are paid out of the assets of the  Portfolio and the
Fund.  The  Portfolio  pays an  investment  advisory  fee and an  administrative
services fee to Bankers Trust and wrapper expenses to the Wrapper  Providers (as
defined  below).  The Fund incurs  additional  administrative  expenses  such as
maintaining shareholder records and furnishing shareholder statements.  The Fund
must also  provide  semi-annual  financial  reports.  The  following  tables are
intended to assist  investors  in  understanding  the expenses  associated  with
investing in the Fund. The expenses  shown on the following  pages are estimates
for the first  full year of  operations.  The table  provides  (i) a summary  of
expenses  related  to  purchases  and  redemptions  (sales)  of  Shares  and the
anticipated  annual  operating  expenses of the Fund and the  Portfolio,  in the
aggregate,  as a  percentage  of  average  daily net  assets and (ii) an example
illustrating  the dollar  cost of such  expenses on a $1,000  investment  in the
Fund.  THE  DIRECTORS  OF THE SECURITY  INCOME FUND  BELIEVE THAT THE  AGGREGATE
EXPENSES  OF THE FUND  (INCLUDING  ITS  PROPORTIONATE  SHARE OF THE  PORTFOLIO'S
EXPENSES) WILL BE LESS THAN OR APPROXIMATELY EQUAL TO THE EXPENSES THAT THE FUND
WOULD INCUR IF IT DIRECTLY  RETAINED THE SERVICES OF AN  INVESTMENT  ADVISER AND
THE  ASSETS OF THE FUND WERE  INVESTED  DIRECTLY  IN  PORTFOLIO  SECURITIES  AND
WRAPPER AGREEMENTS.

1  Purchases of Class A shares in amounts of  $1,000,000 or more are not subject
   to an initial sales load;  however,  a deferred sales charge of 1% is imposed
   in the event of redemption within one year of purchase.
2  Class B shares convert tax-free to Class A shares  automatically  after eight
   years.
3  A deferred  sales charge of 1% is imposed in the event of  redemption  within
   one year of purchase.
- --------------------------------------------------------------------------------

    The  redemption  fee (the  "Redemption  Fee")  payable to the  Portfolio  is
designed  primarily  to  offset  those  expenses  which may be  incurred  by the
Portfolio in connection with certain Shareholder redemptions.  Proceeds from the
Redemption Fee will be used by the Portfolio to defray the actual  portfolio and
administrative  costs  associated with such  redemptions,  including  custodian,
transfer agent, settlement, and account processing costs, as well as the adverse
impact of such  redemptions on the premiums paid for Wrapper  Agreements and the
yield on  Wrapper  Agreements.  The  Redemption  Fee may also have the effect of
discouraging  redemptions initiated by shareholders attempting to take advantage
of short-term interest rate movements.

    Qualified TSA Account  Redemptions (as described in "Redeeming  Shares Owned
Through TSA Accounts and IRAs herein),  Qualified IRA  Redemptions (as described
in "Redeeming  Shares Owned Through TSA Accounts and IRAs" herein) and Qualified
Plan Redemptions (as described in "Redeeming Shares Owned Through Plans" herein)
are not subject to the  Redemption Fee at any time.  All other  redemptions  are
subject to the  Redemption  Fee,  in the amount of 3%, on the  proceeds  of such
redemptions  of  Shares  by  Shareholders  on any day  that the  "Interest  Rate
Trigger" (as  described  below) is "active," and not subject to those charges on
days that the Interest Rate Trigger is "inactive."  The Interest Rate Trigger is
active on any day when, as of the  preceding  day, the  "Reference  Index Yield"
exceeds the sum of the "Annual Effective Yield of the Portfolio" plus 1.80%. The
"Reference  Index  Yield"  shall be  defined  on any  determination  date as the
previous  day's  closing  "Yield to Worst" on the Lehman  Brothers  Intermediate
Treasury  Bond  Index(R) and the "Annual  Effective  Yield of the  Portfolio" is
defined as set forth under "Explanation of Performance Terms" on page 23 herein.
See "Shareholder and Fund Information -- Explanation of Performance Terms".

    The  status  of the  Interest  Rate  Trigger  will  either  be  "active"  or
"inactive"  on any day,  and  shall be  determined  on every  day that an NAV is
calculated  for the  Portfolio.  Once the Interest  Rate  Trigger is active,  it
remains active every day until the Reference Index Yield is less than the sum of
the  Annual  Effective  Yield of the  Portfolio  plus  1.55%,  at which time the
Interest Rate Trigger becomes inactive on the following day and remains inactive
every day thereafter  until it becomes active again. The following is an example
of when and how the Redemption Fee will apply to the redemption of Shares.

EXAMPLE -- A Class A  Shareholder  is  considering  submitting  a request  for a
redemption other than a Qualified TSA Redemption,  a Qualified IRA Redemption or
Qualified Plan Redemption to the Fund on March 2 in the amount of $5,000. Assume
that the  Reference  Index Yield is 8.65% as of the close of business on March 1
and the Annual  Effective Yield of the Portfolio is 6.20% as of that date. Since
the Annual  Effective  Yield of the Portfolio plus 1.80% (8.0%) is less than the
Reference  Index Yield (8.65%),  the Interest Rate Trigger is active.  Thus, the
net redemption  proceeds to the Shareholder  will be $4,850.  The Redemption Fee
will  continue  to  apply  to  all  redemptions  which  are  not  Qualified  TSA
Redemptions,  Qualified IRA Redemptions or Qualified Plan Redemptions  until the
day after the Reference Index Yield is less than the sum of the Annual Effective
Yield of the Portfolio plus 1.55%.

    (Please  note  that  this  example  does  not  take  into  consideration  an
individual Shareholder's tax issues or consequences including without limitation
any withholding taxes that may apply.)

    Shareholders can obtain information regarding when the Interest Rate Trigger
is  active,  as well as the  Annual  Effective  Yield of the  Portfolio  and the
Reference  Index  Yield by  calling  _____________________.  The  amount of, and
method of applying,  the Redemption Fee, including the operation of the Interest
Rate Trigger, may be changed in the future.

    The  expense  table  and the  example  above  show the  estimated  costs and
expenses that a Shareholder will bear directly or indirectly as a shareholder of
the Fund.  Bankers  Trust  has  voluntarily  agreed  to waive a  portion  of its
investment  advisory fee payable by the  Portfolio.  Without  such  waiver,  the
Portfolio's  investment  advisory  fee would be 0.70% of its  average  daily net
assets.  Bankers  Trust has also  voluntarily  agreed to waive a portion  of its
administration fees (included in "Other Expenses").  Without such waiver, "Other
Expenses" would be 0.96%.  Bankers Trust may terminate or adjust these voluntary
waivers and  reimbursements at any time in its sole discretion without notice to
shareholders. In addition, the Wrapper Fees shown above are estimates and may be
greater or less than 0.20%. In addition,  the Administrator has agreed, for each
of the Fund's fiscal years,  to cap the average  annual  expenses of the Fund at
1.5%,   exclusive  of  interest,   taxes,   brokerage   fees  and   commissions,
extraordinary  expenses and 12b-1 fees. The Wrapper Fee expenses incurred by the
Portfolio will be those fees actually charged by the Wrapper  Providers.  In the
absence of these  waivers,  assuming  total  Fund  assets of $5  million,  it is
estimated that "Total  Operating  Expenses" of the Class A shares would be 1.83%
for the Class B shares would be 2.33% and for Class C shares would be 2.08%. THE
EXAMPLE SHOULD NOT BE CONSIDERED A  REPRESENTATION  OF PAST OR FUTURE  EXPENSES,
AND ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN. Moreover, while the
example assumes a 5% annual return,  actual performance will vary and may result
in a return greater or less than 5%.

    For more  information  about the Fund's  and the  Portfolio's  expenses  see
"Management of the Fund" and "Valuation  Details"  herein.  See "How to Purchase
Shares" for more information concerning the sales load. Also, see Appendix A for
a discussion of "Rights of  Accumulation"  and  "Statement  of Intention"  which
options  may serve to reduce the  front-end  sale load on  purchases  of Class A
shorts.

FUND  FINANCIAL  HIGHLIGHTS -- The Fund will have a fiscal year end of September
30. As this is the Fund's first fiscal year, financial  information with respect
to the Fund is not available at this time.

TSA ACCOUNTS, INDIVIDUAL RETIREMENT ACCOUNTS AND RETIREMENT PLANS

OVERVIEW OF TSA  ACCOUNTS  -- In  general,  Section  403(b)(7)  of the  Internal
Revenue Code of 1986, as amended (the "Code")  permits  public school  employees
and  employees  of  certain  types of  charitable,  educational  and  scientific
organizations specified in Section 501(c)(3) of the Code to purchase shares of a
mutual fund through a custodial account, and, subject to certain limitations, to
exclude  the amount of purchase  payments  from gross  income for tax  purposes.
Shares of the Fund may be purchased in connection with a TSA custodial  account.
TSA  Accounts  may  provide  significant  tax  savings to  individuals,  but are
governed  by a  complex  set of tax  rules  under  the Code and the  regulations
promulgated by the Department of the Treasury thereunder.  If you already have a
Security Funds TSA custodial account,  you may be able to invest in the Fund. If
you do not presently  have a Security  Funds TSA custodial  account and you meet
the  requirements  of the  applicable  tax  rules,  you may be able to  create a
Security  Funds TSA custodial  account (or a TSA custodial  account from another
provider that makes shares of the Fund available to its customers) and invest in
shares  of the Fund  through  that  TSA.  Included  in  Appendix  B is a general
discussion  of some TSA  features.  HOWEVER,  TSA OWNERS  AND OTHER  PROSPECTIVE
INVESTORS  SHOULD  CONSULT WITH THEIR  PROFESSIONAL  TAX AND FINANCIAL  ADVISERS
BEFORE ESTABLISHING A TSA OR OTHERWISE INVESTING IN SHARES.

OVERVIEW OF INDIVIDUAL  RETIREMENT  ACCOUNTS -- In general, an IRA is a trust or
custodial account  established in the United States for the exclusive benefit of
an  individual  or his or her  beneficiaries.  (Keogh plans are  established  by
self-employed persons, including partnerships, and also cover eligible non-owner
employees.) Most IRAs are designed  principally as retirement  savings vehicles.
Education  IRAs are  designed  to  provide a  tax-favored  means of saving for a
child's  educational  expenses.  IRAs may  provide  significant  tax  savings to
individuals,  but are  governed  by a complex set of tax rules set out under the
Internal  Revenue Code of 1986,  as amended (the  "Code"),  and the  regulations
promulgated by the Department of the Treasury thereunder. If you already have an
IRA, your IRA may be able to invest in the Fund. If you do not presently have an
IRA and you meet the  requirements of the applicable tax rules,  you may be able
to create an IRA and invest in Shares of the Fund through that IRA.  Included in
Appendix B is a general discussion of some IRA features and IRA types.  HOWEVER,
IRA  OWNERS  AND  OTHER   PROSPECTIVE   INVESTORS   SHOULD  CONSULT  WITH  THEIR
PROFESSIONAL TAX AND FINANCIAL ADVISERS BEFORE  ESTABLISHING AN IRA OR INVESTING
IN  SHARES.  CERTAIN  TYPES  OF THE  IRAS  DESCRIBED  IN  APPENDIX  B MAY NOT BE
AVAILABLE THROUGH THE SECURITY FUNDS. FOR MORE INFORMATION CALL 1-800-888-2461.

OWNERSHIP OF SHARES THROUGH PLANS

Fund Shares owned by Plan Participants through Plans are held either directly by
the respective  Plan, or beneficially  through  vehicles such as bank collective
funds or insurance  company separate  accounts  consisting  solely of such Plans
(collectively, "Plan Pools"), which will in turn offer the Fund as an investment
option  to  their  participants.  Investments  in the  Fund  may  by  themselves
represent  an  investment  option  for a  Plan  or may be  combined  with  other
investments  as part of a pooled  investment  option for the Plan. In the latter
case, the Fund may require Plans to provide information regarding the withdrawal
order and other  characteristics  of any pooled  investment  option in which the
Shares  are  included  prior  to  a  Plan's  initial  investment  in  the  Fund.
Thereafter,  the Fund will require the Plan to provide information regarding any
changes  to the  withdrawal  order  and  other  characteristics  of  the  pooled
investment  option  before such  changes are  implemented.  The Fund in its sole
discretion may decline to sell Shares to Plans if the governing withdrawal order
or other characteristics of any pooled investment option in which the Shares are
included is determined at any time to be disadvantageous to the Fund.

    Plan   Participants   should  contact  their  Plan   administrator   or  the
organization  that  provides  recordkeeping  services  if  they  have  questions
concerning  their  account.  Plan  administrators  and  fiduciaries  should call
__________________ for information regarding a Plan's account with the Fund.

INVESTMENT OBJECTIVES, POLICIES, PRACTICES AND RISK FACTORS

INVESTMENT OBJECTIVES AND POLICIES --

    THE FUND.  The Fund seeks to achieve its  investment  objective by investing
all of its Assets in the Portfolio,  which has the same investment  objective as
the  Fund.  Since the  investment  characteristics  of the Fund will  correspond
directly to those of the Portfolio, the following is a discussion of the various
investments of and techniques employed by the Portfolio.  Additional information
about the investment policies of the Portfolio appears in "Risk Factors Relating
to Fixed  Income  Securities"  herein and in the SAI.  There can be no assurance
that the Fund's and the Portfolio's investment objective will be achieved.

    THE  PORTFOLIO.  The  Portfolio's  investment  objective  is a high level of
current income while seeking to maintain a stable value per Share. The Portfolio
will seek to achieve this objective by investing in the Portfolio Securities and
by entering into Wrapper Agreements,  intended to stabilize the NAV per Share of
the Fund. Each Wrapper Agreement  obligates the Wrapper Provider to maintain the
"Book Value" of a portion of the Portfolio's  assets ("Covered  Assets") up to a
specified  maximum  dollar  amount,  upon the  occurrence  of certain  specified
events.  Generally, the Book Value of the Covered Assets is their purchase price
plus interest on the Covered Assets  accreted at a rate specified in the Wrapper
Agreement ("Crediting Rate"). The Crediting Rate used in computing Book Value is
calculated  by a formula  specified  in the  Wrapper  Agreement  and is adjusted
periodically.  In the case of Wrapper Agreements purchased by the Portfolio, the
Crediting  Rate is the  actual  interest  earned on the  Covered  Assets,  or an
index-based  approximation  thereof,  plus or minus an adjustment  for an amount
receivable from or payable to the Wrapper  Provider based on fluctuations in the
market value of the Covered  Assets.  See  "Overview of Wrapper  Agreements  and
Associated Risks" herein for further detail.

    The  Portfolio  expects to invest at least 65% of its total assets in fixed-
and floating or variable-rate  securities ("Fixed Income Securities") of varying
maturities  rated,  at the time of  purchase,  in one of the top four  long-term
rating categories by Standard & Poor's ("S&P"),  Moody's Investors Service, Inc.
("Moody's"),  or Duff & Phelps Credit Rating Co., or comparably rated by another
nationally  recognized  statistical rating  organization  ("NRSRO"),  or, if not
rated by a NRSRO,  of  comparable  quality as determined by Bankers Trust in its
sole discretion.  For example,  included are those Fixed Income Securities rated
by  S&P in  long-term  rating  categories  ranging  from  AAA to  BBB-  and  the
comparable  categories  of Moody's,  Duff & Phelps Credit Rating Co., or another
NRSRO,  or,  if not  rated by a NRSRO,  deemed to be of  comparable  quality  as
determined by Bankers Trust in its sole discretion.  Further, because high yield
securities will usually offer  higher-yields than higher-rated  securities,  the
Portfolio  may also invest up to ten percent (10%) of its assets in Fixed Income
Securities  rated,  at the time of  purchase  in the fifth  and sixth  long-term
rating  categories  by S&P (i.e.,  BB and B),  Moody's,  or Duff & Phelps Credit
Rating Co., or comparably  rated by another NRSRO,  or, if not rated by a NRSRO,
of comparable quality as determined by Bankers Trust in its sole discretion. See
"Lower Rated Debt Securities" herein.

    WRAPPERS.  In addition to the above,  the Portfolio  will enter into Wrapper
Agreements  with  insurance  companies,  banks or other  financial  institutions
("Wrapper Providers") that are rated, at the time of purchase, in one of the top
two long-term  rating  categories by Moody's or S&P.  There is no active trading
market for Wrapper Agreements, and none is expected to develop;  therefore, they
will be considered  illiquid.  At the time of purchase of any Wrapper Agreement,
the value of all of the Wrapper  Agreements  and any other  illiquid  securities
will not exceed 15% of the Portfolio's net assets.

    FIXED INCOME  SECURITIES.  The Fixed Income Securities  include fixed income
securities  issued  or  guaranteed  by the U.S.  government,  or any  agency  or
instrumentality  thereof;  publicly or privately issued U.S.  dollar-denominated
debt  of  domestic  or  foreign  entities,  including  corporate,  sovereign  or
supranational  entities;  publicly issued U.S. dollar  denominated  asset-backed
securities  issued  by  domestic  or  foreign  entities;  mortgage  pass-through
securities issued by the Government National Mortgage Association ("GNMA"),  the
Federal  Home  Loan  Mortgage  Corporation  ("FHLMC")  or the  Federal  National
Mortgage  Association  ("FNMA");  mortgage  pass-through  securities  issued  by
non-government  entities such as banks,  mortgage  lenders,  or other  financial
institutions, including private label mortgage pass-through securities and whole
loans;  collateralized  mortgage  obligations  ("CMOs") and real estate mortgage
investment conduits ("REMICs"),  which are mortgage-backed debt instruments that
make  payments  of  principal  and  interest at a variety of  intervals  and are
collateralized by any of the aforementioned  mortgage pass-through securities or
whole loans;  and  obligations  issued or  guaranteed,  or backed by  securities
issued  or  guaranteed,  by the  U.S.  government  or any  of  its  agencies  or
instrumentalities,   including   Certificates  of  Accrual  Treasury  Securities
("CATS"),  Treasury  Income Growth  Receipts  ("TIGRs"),  and Treasury  Receipts
("TRs")  and  zero  coupon  securities  (securities  consisting  solely  of  the
principal or interest  component of a U.S.  Treasury bond).  See "Definitions of
Securities Purchased by the Portfolio" herein for a more detailed description of
the foregoing.

    The Portfolio  Securities purchased by the Portfolio also include short-term
investments  rated,  at the time of purchase,  in one of the top two  short-term
rating  categories  by an NRSRO or, if  unrated,  of  comparable  quality in the
opinion  of  the  Adviser,   including   commercial  paper  and  time  deposits,
certificates of deposit, bankers' acceptances,  other instruments of foreign and
domestic banks and thrift  institutions and shares of money market mutual funds.
The  Portfolio  may  invest  up to 35% of its total  assets  in such  short-term
investments for purposes of liquidity and up to 100% of its total assets in such
instruments for temporary defensive purposes.

    GLOBAL ASSET ALLOCATION  ENHANCEMENT.  Although the Portfolio is intended to
be  primarily  invested  in Fixed  Income  Securities,  the  Adviser  intends to
implement  its Global  Asset  Allocation  Strategy  (the "GAA  Strategy")  in an
attempt  to enhance  the  return on the  Portfolio's  Assets.  The GAA  Strategy
employs a multi-factor,  global asset allocation  model which evaluates  equity,
bond, cash and currency opportunities across domestic and international markets.
The  GAA  Strategy  seeks  to  enhance  long-term  returns  and  manage  risk by
responding  effectively to changes in global markets using instruments including
but not limited to, futures, options and currency forwards.

    In  implementing  the GAA  Strategy,  the  Portfolio  invests in options and
futures  based on any type of  security or index  including  options and futures
traded  on  foreign  exchanges  such as bonds  and  equity  indices  of  foreign
countries.  Some  options and futures  strategies,  including  selling  futures,
buying puts, and writing calls, hedge the Portfolio's  investments against price
fluctuations.  Other  strategies,  including  buying futures,  writing puts, and
buying calls, tend to increase and will broaden the Portfolio's market exposure.
Options and futures may be combined with each other, or with forward  contracts,
in order to adjust the risk and return  characteristics  of an overall strategy.
The  Portfolio  may  also  enter  into  forward  currency   exchange   contracts
(agreements to exchange one currency for another at a future date),  may buy and
sell  options and futures  contracts  relating  to foreign  currencies,  and may
purchase   securities  indexed  to  foreign   currencies.   Currency  management
strategies allow the Adviser to shift  investment  exposure from one currency to
another or to  attempt to profit  from  anticipated  declines  in the value of a
foreign  currency  relative to the U.S.  dollar.  Some of these  strategies will
require the Portfolio to segregate liquid assets in a custodial account to cover
its  obligations.  See  "Definitions  of Securities  Purchased by the Portfolio"
herein. For further information  regarding the GAA Strategy,  you should consult
"Investment Policies -- Global Asset Allocation Enhancement" in the Fund's SAI.

    The Portfolio may also invest in and utilize the following  investments  and
investment  techniques  and  practices:  Rule 144A  securities  (as  defined  in
"Securities and Investment Practices of the Portfolio"), when-issued and delayed
delivery securities,  repurchase  agreements,  reverse repurchase agreements and
dollar rolls, and options and futures contracts.  See "Definitions of Securities
Purchased  by the  Portfolio"  herein  for a more  detailed  description  of the
foregoing.

    OTHER PORTFOLIO INFORMATION.  In selecting securities for the Portfolio, the
Adviser  attempts  to maintain an average  portfolio  duration of the  Portfolio
Securities  within a range of 2.5 to 4.5  years.  Duration  is a measure  of the
expected  life of a  Fixed  Income  Security  on a  present  value  basis  which
incorporates the security's yield, coupon interest payments,  final maturity and
call features into a single measure.

    The  Fund's  investment  objective  is not a  fundamental  policy and may be
changed upon notice to, but without the need for approval of, its  shareholders.
If there is a change in the Fund's investment objective, its shareholders should
consider  whether the Fund remains an  appropriate  investment in light of their
then-current  needs.  The  investment  objective of the Portfolio  also is not a
fundamental policy. Shareholders of the Fund will receive 30 days' prior written
notice with respect to any change in the investment objective of the Fund or the
Portfolio.  See  "Investment  Restrictions"  in the SAI for a description of the
fundamental policies of the Portfolio that cannot be changed without approval by
"the vote of a majority of the outstanding voting securities" (as defined in the
Investment Company Act of 1940 (the "1940 Act") ) of the Portfolio.

INVESTMENT PRACTICES OF THE PORTFOLIO --

    BORROWING.  The Portfolio will not borrow money  (including  through reverse
repurchase  agreements or dollar roll transactions) for any purpose in excess of
5% of its total  assets,  except that it may borrow for  temporary  or emergency
purposes up to 1/3 of its total  assets.  Under the 1940 Act,  the  Portfolio is
required  to maintain  continuous  asset  coverage of 300% with  respect to such
borrowings  and to sell (within  three days)  sufficient  portfolio  holdings to
restore  such  coverage  if it  should  decline  to less than 300% due to market
fluctuations or otherwise,  even if such liquidation of the Portfolio's holdings
may be disadvantageous from an investment standpoint.

    Leveraging by means of borrowing may  exaggerate  the effect of any increase
or decrease in the value of the  Portfolio's  securities  and the Fund's NAV per
Share, and money borrowed by the Portfolio will be subject to interest and other
costs (which may include commitment fees and/or the cost of maintaining  minimum
average  balances)  that may  exceed  the income  received  from the  securities
purchased with the borrowed funds. It is not the intention of the Adviser to use
leverage as a normal practice in the investment of the Portfolio's Assets.

    HEDGING  STRATEGIES.  The Portfolio may use certain  strategies  designed to
adjust the overall risk of its investment portfolio.  These "hedging" strategies
involve  derivative  contracts,  including U.S. Treasury and Eurodollar  futures
contracts and  exchange-traded  put and call options on such futures  contracts.
New financial products and risk management  techniques  continue to be developed
and may be used if  consistent  with the  Portfolio's  investment  objective and
policies.  Among  other  purposes,  these  hedging  strategies  may be  used  to
effectively  maintain a desired portfolio  duration or to protect against market
risk should the Portfolio change its investments  among different types of Fixed
Income  Securities.  In this respect,  these hedging strategies are designed for
different purposes than the investments in Wrapper Agreements.  The SAI contains
further information on these strategies.

    The  Portfolio  might not use any  hedging  strategies,  and there can be no
assurance  that any strategy used will  succeed.  If the Adviser is incorrect in
its judgment on market values, interest rates or other economic factors in using
a hedging  strategy,  the  Portfolio may have lower net income and a net loss on
the investment.

    Each of these  strategies  involves certain risks,  which include:  the fact
that the skills  needed to use  hedging  instruments  are  different  from those
needed to select  securities  for the  Portfolio;  the  possibility of imperfect
correlation,  or even no  correlation,  between the price  movements  of hedging
instruments  and price  movements of the securities or currencies  being hedged;
possible  constraints  placed on the  Portfolio's  ability to  purchase  or sell
portfolio investments at advantageous times due to the need for the Portfolio to
maintain  "cover"  or to  segregate  securities;  and the  possibility  that the
Portfolio will be unable to close out or liquidate its hedged position.

    ASSET COVERAGE.  To assure that the Portfolio's use of futures contracts and
related options, as well as when-issued and delayed-delivery securities, are not
used to achieve investment leverage, the Portfolio will cover such transactions,
as required under  applicable  interpretations  of the SEC, either by owning the
underlying securities or by segregating or earmarking liquid securities with the
Portfolio's  Custodian  (Bankers  Trust) in an  amount at all times  equal to or
exceeding  the  Portfolio's  commitment  with  respect to these  instruments  or
contracts.  The Portfolio  will also cover its use of Wrapper  Agreements to the
extent required to avoid the creation of a "senior  security" (as defined in the
1940 Act) in connection with its use of such agreements.

    GAA STRATEGY. In connection with the GAA Strategy,  the Board of Trustees of
the Portfolio has adopted a restriction  that the Portfolio  will not enter into
any futures contracts or option on futures  contracts if immediately  thereafter
the amount of margin  deposits on all of the futures  contracts of the Portfolio
and  premiums  paid on  outstanding  options  on futures  contract  owned by the
Portfolio  (other than those entered into for bona fide hedging  purposes) would
exceed  five  percent  (5%) of the  market  value  of the  total  assets  of the
Portfolio.

RISK FACTORS -- The value of most of the  Portfolio  Securities  will  fluctuate
based upon changes in domestic or foreign  interest rates, the credit quality of
the issuer,  market  conditions,  and other  economic  and  political  news.  In
general,  the prices of Portfolio Securities will rise when interest rates fall,
and fall when  interest  rates rise.  The  Wrapper  Agreements  are  intended to
stabilize  the value per Share by  offsetting  fluctuations  in the value of the
Portfolio  Securities under certain conditions.  Under most  circumstances,  the
combination of Portfolio Securities and Wrapper Agreements held by the Portfolio
is expected to provide  Fund  shareholders  with a constant  NAV per Share and a
current rate of return that is higher than most money  market  mutual funds over
most time periods.  However,  there can be no guarantee  that the Portfolio will
maintain a constant NAV, and consequently that the Fund will be able to maintain
a constant NAV per Share.

    The  Portfolio  incurs costs in  connection  with its  investment in Wrapper
Agreements  which  will  reduce  the  Fund's  investment   return.  The  Wrapper
Agreements  may not insulate the  Portfolio  from loss if an issuer of Portfolio
Securities  defaults on payments of  interest  or  principal.  Additionally,  an
issuer  of a  Wrapper  Agreement  could  default  on its  obligations  under the
agreement or the Portfolio might be unable to obtain Wrapper Agreements covering
all of its assets.  Either type of default or the  inability  to obtain  Wrapper
Agreements  might result in a decline in the value of the Shares.  Moreover,  in
valuing a Wrapper  Agreement,  the Board of Trustees of the Portfolio  Trust may
determine that such agreement  should not be carried by the Portfolio at a value
sufficient to maintain the Portfolio's NAV per Share.

    Bankers Trust may use various investment techniques to hedge the Portfolio's
risks,  but there is no guarantee that these  strategies  will work as intended.
See "Risk Factors Related to Fixed Income Securities" for more information.

RISK FACTORS  RELATING TO PORTFOLIO  SECURITIES -- The  following  pages contain
more detailed  information  about the specific types of instruments in which the
Portfolio  may invest and  strategies  the  Adviser may employ in pursuit of the
Portfolio's  investment  objective.  A summary  of the  risks  and  restrictions
associated with these investments and investment practices is included as well.

    The  Adviser  may not  buy  all of  these  instruments  or use all of  these
techniques  to the full extent  permitted  unless it believes that doing so will
help the  Portfolio  achieve its  objective.  Current  holdings  and  investment
strategies  will be  described  in the  financial  reports  of the  Fund and the
Portfolio, which will be sent to Fund shareholders twice a year.

    All fixed income  investments have exposure to three primary types of risks.
Credit risk is the  possibility  that the issuer of a Fixed Income Security will
fail to make timely  payments of either  interest or principal to the Portfolio.
Interest  rate risk is the  potential  for  fluctuations  in the prices of Fixed
Income Securities due to changing  interest rates.  Income risk is the potential
for decline in the  Portfolio's  income due to the investment or reinvestment of
assets in Fixed Income Securities when market interest rates are falling.

    Although  there is no  assurance  that it will  achieve its  objective,  the
Portfolio  attempts to enhance yield while  minimizing these risks. If an issuer
of a Fixed Income Security or a Wrapper Provider becomes  financially  impaired,
it may default on its  obligations  and the  Portfolio's  interest income may be
reduced or the Portfolio  may incur a loss of  principal.  This is an example of
credit  risk.  In order to minimize  credit  risk,  the  Portfolio's  assets are
allocated  among a diversified  group of issuers.  Credit analysis is applied to
every security and Wrapper Provider selected for the Portfolio.  Once purchased,
a security  and, in the case of a Wrapper  Agreement,  the  Wrapper  Provider is
monitored  regularly  by  Bankers  Trust  for  maintenance  of  adequate  credit
characteristics.  In the event that the rating of a security or Wrapper Provider
is  downgraded  by one or more  NRSRO,  the  Portfolio  may elect to retain  the
security or applicable Wrapper Agreement.  However,  some Wrapper Agreements may
require  that  Fixed  Income  Securities  that fall  below  investment  grade be
liquidated  within a set time  period  typically  within  one year or less.  The
Portfolio  may elect  not to cover  with  Wrapper  Agreements  any Fixed  Income
Securities  with a  remaining  maturity of 60 days or less and any cash or short
term investments.

    When interest rates rise,  Fixed Income Security prices  generally  decline.
When interest  rates fall,  Fixed Income  Security  prices  generally  increase.
Generally,  the longer the maturity of the Fixed Income Security, the higher its
yield,  although  longer-term  Fixed Income  Securities tend to offer less price
stability  in  response  to  changes  in  interest  rates  than do  shorter-term
investments.  Therefore, portfolios with shorter average maturities tend to have
less risk and lower returns than portfolios with longer average maturities. This
is an  example  of  interest  rate risk.  In order to help  maintain  an average
portfolio  duration of 2.5 to 4.5 years,  the Portfolio will invest primarily in
Fixed Income  Securities of short- to  intermediate-term  maturities.  This will
help to minimize interest rate risk. In addition,  unlike most traditional fixed
income portfolios, the Portfolio purchases Wrapper Agreements that should offset
substantially  all  of  the  price   fluctuations   typically   associated  with
longer-term Fixed Income Securities.

    It is important to note the distinction between the Portfolio and short-term
investments  such as money market funds.  The  securities  held by the Portfolio
have a longer average maturity than those of money market funds. Because a money
market fund has a shorter average  maturity,  its yield will track the direction
of current market rates of return more closely than the Portfolio.  For example,
in a rising interest rate environment, money market yields may rise more quickly
than those of the  Portfolio.  In a falling  interest  rate  environment,  money
market  yields  may fall more  quickly  than  those of the  Portfolio.  Over the
long-term,  however,  intermediate and long-term Fixed Income Securities such as
those  purchased by the Portfolio have  historically  offered higher yields than
short-term investments (i.e., money market funds).

LOWER-RATED  DEBT SECURITIES  ("JUNK BONDS") -- The Portfolio may invest in debt
securities  rated in the fifth and sixth  long-term  rating  categories  by S&P,
Moody's and Duff & Phelps Credit Rating Company,  or comparably rated by another
NRSRO,  or if not  rated by a  NRSRO,  deemed  to be of  comparable  quality  as
determined  by the  Adviser  in its sole  discretion.  While the market for high
yield  corporate  debt  securities  has been in existence for many years and has
weathered previous economic downturns, the 1980's brought a dramatic increase in
the use of such securities to fund highly leveraged  corporate  acquisitions and
restructuring.  Past experience may not provide an accurate indication of future
performance of the high yield bond market, especially during periods of economic
recession.  In fact,  from 1989 to 1991,  the  percentage  of  lower-rated  debt
securities that defaulted rose significantly  above prior levels. The market for
lower-rated  debt  securities  may be  thinner  and less  active  than  that for
higher-rated debt securities, which can adversely affect the prices at which the
former  are sold.  If market  quotations  are not  available,  lower-rated  debt
securities will be valued in accordance with procedures established by the Board
of Trustees,  including the use of outside  pricing  services.  Judgment plays a
greater role in valuing high yield  corporate debt  securities  than is the case
for  securities  for which more external  sources for  quotations  and last sale
information is available. Adverse publicity and changing investor perception may
affect the  availability of outside pricing  services to value  lower-rated debt
securities and the Portfolio's ability to dispose of these securities.

    Since the risk of default is higher for  lower-rated  debt  securities,  the
Adviser's  research and credit  analysis  are an  especially  important  part of
managing  securities  of  this  type  held  by  the  Portfolio.  In  considering
investments  for the  Portfolio,  the Adviser  will  attempt to  identify  those
issuers of high-yielding debt securities whose financial conditions are adequate
to meet future  obligations,  have  improved  or are  expected to improve in the
future.  The Adviser's analysis focuses on relative values based on such factors
as interest on dividend  coverage,  asset coverage,  earnings  prospects and the
experience and managerial  strength of the issuer.  The Portfolio may choose, at
its expense or in  conjunction  with others,  to pursue  litigation or otherwise
exercise  its rights as a security  holder to seek to protect  the  interest  of
security holders if it determines this to be in the interest of the Portfolio.

OVERVIEW OF WRAPPER  AGREEMENTS AND ASSOCIATED RISKS -- As discussed above, each
Wrapper Agreement obligates the Wrapper Provider to maintain the "Book Value" of
the Covered Assets up to a specified maximum dollar amount,  upon the occurrence
of  certain  specified  events.  The Book Value of the  Covered  Assets is their
purchase  price (i) plus interest on the Covered  Assets at the Crediting  Rate,
and (ii) less an adjustment to reflect any defaulted  securities.  The Crediting
Rate used in computing  Book Value is calculated  by a formula  specified in the
Wrapper  Agreement  and  is  adjusted  periodically.  In  the  case  of  Wrapper
Agreements purchased by the Portfolio, the Crediting Rate is the actual interest
earned on the Covered Assets, or an index-based  approximation  thereof, plus or
minus an  adjustment  for an amount  receivable  from or payable to the  Wrapper
Provider based on fluctuations  in the market value of the Covered Assets.  As a
result,  while the Crediting Rate will generally reflect movements in the market
rates of  interest,  it may at any time be more or less than these  rates or the
actual interest income earned on the Covered Assets. The Crediting Rate may also
be impacted by defaulted securities and by increases and decreases of the amount
of  Covered  Assets as a result of  contributions  and  withdrawals  tied to the
purchase  and  redemption  of Shares.  Furthermore,  the  premiums  due  Wrapper
Providers in connection with the Portfolio's  investments in Wrapper  Agreements
are offset against  interest  earned and thus reduce the Crediting  Rate.  These
premiums are generally paid quarterly.  In no event will the Crediting Rate fall
below 0% under the Wrapper Agreements entered into by the Portfolio.

    Generally, under the terms of a Wrapper Agreement, if the market value (plus
accrued  interest on the  underlying  securities)  of the Covered Assets is less
than their Book Value at the time the Covered  Assets are liquidated in order to
provide  proceeds  for  withdrawals  of  Portfolio   interests   resulting  from
redemptions of Shares by Shareholders, the Wrapper Provider becomes obligated to
pay to the Portfolio the difference. Conversely, the Portfolio becomes obligated
to make a payment to the Wrapper  Provider if it is necessary  for the Portfolio
to liquidate  Covered  Assets at a price above their Book Value in order to make
withdrawal  payments.  (Withdrawals  generally will arise when the Fund must pay
shareholders  who redeem  Shares.)  Because it is anticipated  that each Wrapper
Agreement will cover all Covered Assets up to a specified dollar amount, if more
than  one  Wrapper  Provider  becomes  obligated  to pay to  the  Portfolio  the
difference  between  Book Value and market value (plus  accrued  interest on the
underlying  securities),  each  Wrapper  Provider  will  be  obligated  to pay a
pro-rata amount in proportion to the maximum dollar amount of coverage provided.
Thus, the Portfolio will not have the option of choosing which Wrapper Agreement
to draw upon in any such payment situation.

    The terms of the Wrapper Agreements vary concerning when these payments must
actually be made between the Portfolio and the Wrapper Provider.  In some cases,
payments may be due upon disposition of Covered Assets; other Wrapper Agreements
provide  for  settlement  of  payments  only  upon  termination  of the  Wrapper
Agreement or total liquidation of the Covered Assets.

    The Fund expects that the use of Wrapper  Agreements by the  Portfolio  will
under most  circumstances  permit the Fund to maintain a constant NAV and to pay
dividends that will generally reflect over time both the interest income of, and
market gains and losses on, the Covered  Assets held by the  Portfolio  less the
expenses of the Fund and the Portfolio.  However, there can be no guarantee that
the Fund will  maintain a constant  NAV per Share or that any  Shareholder  will
realize the same investment return as might be realized by investing directly in
the Portfolio assets other than the Wrapper  Agreements.  For example, a default
by the issuer of a Portfolio  Security or a Wrapper  Provider on its obligations
might  result  in  a  decrease  in  the  value  of  the  Portfolio  assets  and,
consequently,  the Shares. The Wrapper  Agreements  generally do not protect the
Portfolio from loss if an issuer of Portfolio Securities defaults on payments of
interest or principal. Additionally, a Fund shareholder may realize more or less
than the actual  investment  return on the  Portfolio  Securities.  Furthermore,
there can be no assurance that the Portfolio will be able at all times to obtain
Wrapper  Agreements.  Although it is the current  intention of the  Portfolio to
obtain such agreements  covering all of its assets (with the exceptions  noted),
the  Portfolio  may elect not to cover  some or all of its assets  with  Wrapper
Agreements  should  Wrapper   Agreements  become  unavailable  or  should  other
conditions  such as cost,  in Bankers  Trust's  sole  discretion,  render  their
purchase inadvisable.

    If, in the event of a default  of a Wrapper  Provider,  the  Portfolio  were
unable to obtain a replacement Wrapper Agreement,  Shareholders redeeming Shares
might experience losses if the market value of the Portfolio's  assets no longer
covered by the Wrapper  Agreement is below Book Value.  The  combination  of the
default of a Wrapper Provider and an inability to obtain a replacement agreement
could  render the  Portfolio  and the Fund  unable to achieve  their  investment
objective of maintaining a stable NAV per Share. If the Board of Trustees of the
Portfolio Trust (the "Portfolio Trust Board") determines that a Wrapper Provider
is unable to make  payments  when due, that Board may assign a fair value to the
Wrapper  Agreement that is less than the  difference  between the Book Value and
the market value (plus accrued  interest on the  underlying  securities)  of the
applicable  Covered  Assets and the  Portfolio  might be unable to maintain  NAV
stability.

    Some  Wrapper  Agreements  require that the  Portfolio  maintain a specified
percentage of its total assets in short-term investments  ("Liquidity Reserve").
These  short-term  investments  must be used for the payment of withdrawals from
the Portfolio and Portfolio expenses.  To the extent the Liquidity Reserve falls
below the specified  percentage  of total assets,  the Portfolio is obligated to
direct all net cash flow to the  replenishment  of the  Liquidity  Reserve.  The
obligation to maintain a Liquidity  Reserve may result in a lower return for the
Portfolio  and the Fund than if these funds were invested in  longer-term  Fixed
Income  Securities.  The Liquidity Reserve required by all Wrapper Agreements is
not expected to exceed 20% of the Portfolio's total assets.

    Wrapper  Agreements  also require  that the Covered  Assets have a specified
duration  or  maturity,  consist of  specified  types of  securities  or be of a
specified  investment  quality.  The Portfolio will purchase Wrapper  Agreements
whose  criteria  in this regard are  consistent  with the  Portfolio's  (and the
Fund's)  investment  objective  and policies as  described  in this  Prospectus.
Wrapper  Agreements may also require the disposition of securities whose ratings
are downgraded below a certain level. This may limit the Portfolio's  ability to
hold such downgraded  securities.  Please see the SAI for additional information
concerning Wrapper Agreements.

DERIVATIVES  -- The Portfolio may invest in various  instruments,  including the
Wrapper Agreements, that are commonly known as "derivatives." Broadly defined, a
derivative  is a  financial  arrangement  the  value of which  is based  on,  or
"derived" from, a traditional security,  asset or market index. Some derivatives
such as mortgage-related and other asset-backed  securities are in many respects
like any other  investments,  although  they may be more volatile or less liquid
than more traditional debt securities.  There are, in fact, many different types
of derivatives  and many different ways to use them.  There are a range of risks
associated with those uses.  Futures contracts and options are commonly used for
traditional  hedging purposes to attempt to protect an investor from exposure to
changing  interest rates,  securities  prices or currency exchange rates and for
cash  management  purposes  as a  low  cost  method  of  gaining  exposure  to a
particular  securities  market without  investing  directly in those securities.
However,  some  derivatives  are used for  leverage,  which tends to magnify the
effect of an instrument's  price changes as market conditions  change.  Leverage
involves  the use of a small  amount  of  money to  control  a large  amount  of
financial  assets and can, in some  circumstances,  lead to significant  losses.
Bankers  Trust uses  derivatives  only in  circumstances  where it believes they
offer the most  economic  means of  improving  the  risk/reward  profile  of the
Portfolio.  Except as noted  herein,  derivatives  will not be used to  increase
portfolio  risk above the level that could be  achieved  using only  traditional
investment  securities or to acquire  exposure to changes in the value of assets
or indexes that by themselves would not be purchased for the Portfolio.  The use
of derivatives for non-hedging purposes may be considered speculative.

    GAA STRATEGY. In implementing the GAA Strategy,  the Portfolio's  investment
in  derivatives  such as  options,  futures or forward  contracts,  and  similar
strategies  depend  on the  Adviser's  judgment  as to the  potential  risks and
rewards of implementing  the different types of strategies.  Options and futures
can be volatile  investments,  and may not perform as  expected.  If the Adviser
applies a hedge at an  inappropriate  time or judges price  trends  incorrectly,
options and futures strategies may lower the Portfolio's  return.  Additionally,
options and futures traded on foreign  exchanges  generally are not regulated by
U.S.  authorities,  and may  offer  less  liquidity  and  less  protection  to a
Portfolio  in the event of  default  by the  other  party to the  contract.  The
Portfolio could also experience  losses if the prices of its options and futures
positions were poorly correlated with its other investments,  or if it could not
close out its positions because of an illiquid secondary market.

HOW TO PURCHASE SHARES

    Security Distributors,  Inc. (the "Distributor"),  a wholly-owned subsidiary
of Security Benefit Group,  Inc., is principal  underwriter for the Fund. Shares
of the Fund may be purchased through authorized investment dealers. In addition,
banks  and  other  financial  intermediaries  that  have an  agreement  with the
Distributor  may make  shares  of the Fund  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 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 -- The Fund offers three 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  A on page 31 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.

    CLASS C SHARES - BACK-END  LOAD  OPTION.  Class C shares are sold  without a
sales charge at the time of purchase, but are subject to a deferred sales charge
of 1% if they are  redeemed  within  one year of the date of  purchase.  Class C
shares do not automatically convert to any other share class.

    The  decision  as to which  share  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 or Class C 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.

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

CLASS A SHARES -- Class A shares of the Fund are offered at net asset value plus
an initial sales charge as follows:

$1,000,000 and over..............      None              None        (See below)
- --------------------------------------------------------------------------------

    Purchases of Class A shares 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 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" on page 16.

    The  Distributor  will pay a  commission  to  dealers on such  purchases  of
$1,000,000 or more as follows:  ______% on sales up to $5,000,000,  plus ______%
on sales of  $5,000,000 or more up to  $10,000,000  and ______% on any amount of
$10,000,000 or more.

CLASS A DISTRIBUTION PLAN -- In addition to the sales charge deducted from Class
A  shares  at the  time  of  purchase,  the  Fund is  also  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.  The Fund's
Class A  Distribution  Plan  permits  payments  to be  made  by the  Fund to the
Distributor,  to finance various activities  relating to the distribution of its
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 Fund.

    Under the  Class A  Distribution  Plan,  a  monthly  payment  is made to the
Distributor in an amount computed at an annual rate of .25% of the average daily
net asset value of the Fund's Class A shares.  The  distribution  fees collected
may be used by the Fund and the other series of Security  Income Fund to finance
joint distribution activities,  for example advertisements promoting each of the
funds,  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
the Fund 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% 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  Fund's  Class  A
shareholders.   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 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 the Fund. Other promotional activities which
may be  financed  pursuant  to  the  Plan  include  (i)  informational  meetings
concerning the Fund for registered  representatives interested in selling shares
of the Fund, 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
the Fund by the  registered  representatives  employed  by such  dealer(s).  The
expenses associated with the foregoing  activities will include travel expenses,
including lodging.

    The Class A  Distribution  Plan may be terminated at any time by vote of the
directors of the Fund, who are not interested  persons of the Fund as defined in
the 1940 Act or by vote of a majority of the Fund's  outstanding Class A shares.
In the event the Class A Distribution  Plan is terminated,  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 the Fund are  offered  at net asset  value,
without an initial sales charge. With certain exceptions,  the Fund 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 shareholder  made a purchase
payment  from  which an amount is being  redeemed,  according  to the  following
schedule:

                  --------------------------------------------
                                                   CONTINGENT
                            YEAR SINCE              DEFERRED
                        PURCHASE WAS MADE         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  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 transfer agent.) 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  shareholder  may  receive  more or less Class A shares than the
number of Class B shares converted.  Under current law, it is the Fund's 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 shareholders.

CLASS B  DISTRIBUTION  PLAN -- The Fund 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").  The Class B  Distribution  Plan provides for
payments at an annual  rate of .75% of the average  daily net asset value of the
Class B shares.  Amounts paid by the Fund 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 3% of the value of each
share sold, and (2) a service fee payable for the first year, initially, and for
each year  thereafter,  quarterly,  in an amount  equal to .25%  annually of the
average  daily net asset value of Class B shares sold by such  dealers and other
firms and remaining outstanding on the books of the Fund.

    NASD Rules  limit the  aggregate  amount  that the 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  Class B  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 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
Fund. 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 Fund would be
within permitted limits.

    The 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,  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 Fund makes no payments in
connection with the sale of their Class B shares other than the distribution fee
paid to the Distributor.

CLASS C SHARES -- Class C shares  of the Fund are  offered  at net asset  value,
without an initial sales charge. With certain exceptions, the Fund will impose a
deferred sales charge on Class C shares  redeemed within one year 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.

CLASS C  DISTRIBUTION  PLAN -- The Fund bears  some of the costs of selling  its
Class C shares  under a  Distribution  Plan  adopted with respect to its Class C
shares ("Class C Distribution  Plan") pursuant to Rule 12b-1 under the 1940 Act.
The Class C Distribution Plan provides for payments at an annual rate of .50% of
the  average  daily net asset value of the Class C shares.  Amounts  paid by the
Fund are currently  used to pay dealers and other firms that make Class C shares
available to their  customers (1) a commission at the time of purchase  normally
equal to .25% of the value of each  share  sold,  and for each year  thereafter,
quarterly,  in an amount equal to .25%  annually of the average  daily net asset
value of Class C shares  sold by such  dealers  and other  firms  and  remaining
outstanding  on the books of the Fund,  and (2) a service  fee  payable  for the
first year,  initially,  and for each year thereafter,  quarterly,  in an amount
equal to .25%  annually of the  average  daily net asset value of Class C shares
sold by such dealers and other firms and remaining  outstanding  on the books of
the Fund.

    NASD Rules  limit the  aggregate  amount  that the Fund may pay  annually in
distribution costs for the sale of its Class C shares to 6.25% of gross sales of
Class C shares  since the  inception  of the  Class C  Distribution  Plan,  plus
interest at the prime rate plus 1% on such amount (less any contingent  deferred
sales charges paid by Class C shareholders to the Distributor).  The Distributor
intends,  but is not  obligated,  to  continue  to apply or accrue  distribution
charges  incurred in connection with the Class C Distribution  Plan which exceed
current annual  payments  permitted to be received by the  Distributor  from the
Fund. 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 Fund would be
within permitted limits.

    The Fund's Class C  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 C shares.  In the
event the Class C  Distribution  Plan is  terminated,  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 Fund makes no payments in
connection with the sale of their Class C 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  or Class C 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;  (3) Class A shares (purchased in an amount of $1,000,000 or
more) or Class C shares held for more than one year;  or (4) 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
shareholder  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.

CONFIRMATIONS  AND  STATEMENTS  -- Certain  transactions  may be  confirmed on a
quarterly  basis  including  systematic  withdrawals,  automatic  purchases  and
reinvested dividends.

PURCHASES AT NET ASSET VALUE

    Class A shares  of the  Fund  may be  purchased  at net  asset  value by (1)
directors,  officers and  employees  of the Fund,  the Fund's  Administrator  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 Fund.

    Class A shares of the Fund 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.

PURCHASING SHARES THROUGH PLANS

Plan  participant-directed  purchases,  exchanges and  redemptions of Shares are
handled in  accordance  with each  Plan's  specific  provisions.  Plans may have
different  provisions  with  respect  to the  timing  and  method of  purchases,
exchanges and redemptions by Plan Participants. Plan Participants should contact
their Plan administrator for details concerning how they may direct transactions
in Shares.  It is the  responsibility  of the Plan  administrator  or other Plan
service  provider  to  forward   instructions  for  these  transactions  to  the
Administrator.

PURCHASING SHARES THROUGH TSA ACCOUNTS AND IRAS

Shares may be  purchased  through a TSA Account or an IRA  established  with the
Security  Funds by calling the  Distributor  at  1-800-888-2461.  Alternatively,
Shares may be  purchased  through a TSA  Account or an IRA  established  with an
authorized investment dealer or other financial  intermediary that has a selling
agreement  with  the  Distributor   (collectively  referred  to  as  "Investment
Dealers").

    For information  regarding opening a TSA Account or an IRA account, call the
Distributor at  1-800-888-2461  or contact your Investment  Dealer, or address a
written request to:

                           Security Distributors, Inc.
                           P.O. Box __________________

HOW TO REDEEM SHARES

A Shareholder may redeem shares at the net asset value next determined after the
time when such shares are tendered for redemption,  less any applicable deferred
sales charge and Redemption Fee.

    Shares will be redeemed on request of the shareholder in proper order to the
Fund's  Administrator.  A request  is made in  proper  order by  submitting  the
following  items to the  Administrator:  (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  Administrator 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  shareholders of record for an
account,  to be sent to the address of record.  The Transfer  Agent 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  Administrator  by calling
1-800-888-2461, extension 3127.

    Payment of the amount due on redemption,  less any applicable deferred sales
charge  and  Redemption  Fee,  will  be  made by  check  or by wire at the  sole
discretion  of  the  Administrator,  within  seven  days  after  receipt  of the
redemption  request  in proper  order.  If a wire  transfer  is  requested,  the
Administrator  must be provided  with the name and address of the  shareholder's
bank as well as the account number to which payment is to be wired.  Checks will
be mailed to the shareholder'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.

    In addition to the foregoing  redemption  procedures,  the Fund  repurchases
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
shareholder's  tax  identification  number  has  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.

    The Fund  reserves the right to honor any request for  redemption  by making
payment in whole or in part in securities  selected  solely in the discretion of
the Fund provided,  however,  that such  "securities"  shall not include Wrapper
Agreements.  The Fund intends to exercise this right under certain extraordinary
conditions  as  determined  by the Fund.  To the extent that  payment is made in
securities,  a shareholder  may incur  brokerage  expenses in  converting  these
securities into cash. Please see the Fund's Statement of Additional  Information
for additional information concerning redemptions in kind.

REDEEMING SHARES OWNED THROUGH PLANS -- Redemption requests will be processed at
the NAV per share next determined  after a request for redemption is received in
good order by the  Administrator,  less any  applicable  deferred  sales charge.
There  will  be  no  reduction  of  the  NAV  per  Share  for  "Qualified   Plan
Redemptions," which are redemptions  resulting from a Plan Participant's  death,
disability,  retirement or termination of employment or to fund loans to, or "in
service" withdrawals by, a Plan Participant,  other than the possible assessment
of a contingent  deferred sales charge as described above. All other redemptions
of Shares,  including those to fund transfers to other Plan investment  options,
will be  subject to the 3%  Redemption  Fee,  if the  Interest  Rate  Trigger is
active. See "EXPENSE SUMMARY" and "Shareholder Transaction Expenses" above.

    The  Fund  and the  Administrator  reserve  the  right  to  require  written
verification of whether a redemption  request is for a Qualified Plan Redemption
in accordance  with Plan  provisions and to establish the  authenticity  of this
information before processing a redemption request. Normally, the Fund will make
payment  for all  Shares  redeemed  within one  business  day after a request is
received. In no event will payment be made more than seven days after receipt of
a redemption request in good order. The Fund may suspend the right of redemption
or  postpone  the date of  payment  at times  when both the NYSE and the  Fund's
Administrator are closed, or under any emergency  circumstances as determined by
the SEC.

    The value of Shares at the time of  redemption  may be more or less than the
Plan Participant's cost at the time of purchase, depending upon the then-current
market  value  of the  Fund's  assets  (its  interest  in the  Portfolio).  Plan
Participants  should consult with their Plan administrator  and/or  professional
tax adviser with respect to the terms and  conditions  for  withdrawal  from, or
redemption of their interests in, their respective Plans.

REDEEMING  SHARES OWNED THROUGH TSA ACCOUNTS AND IRAS -- Redemption  Requests by
Owners of TSA Accounts and IRA Owners should be transmitted  in accordance  with
procedures established by the Administrator.  Requests for redemptions of Shares
held  through TSA  Accounts  and IRAs must be made in writing and  describe  the
nature  of the  redemption  in order to be  deemed  "in good  order."  Forms are
available from the Security Funds Service Center at  1-800-888-2461 or from your
Investment Dealer.

    Redemption  requests  initiated by Owners f TSA Accounts and IRA Owners will
be processed at the NAV per Share next determined after a request for redemption
is received in good order by the Transfer  Agent,  less any applicable  deferred
sales charge. Normally, the Fund will make payment for all Shares redeemed under
this  procedure  within one  business  day after a request is  received  in good
order.  In no event will payment be made more than seven days after receipt of a
redemption  request in good order.  The Fund may suspend the right of redemption
or  postpone  the date of  payment  at times  when both the NYSE and the  Fund's
Transfer Agent are closed, or under any emergency circumstances as determined by
the SEC.

    The value of Shares at the time of  redemption  may be more or less than the
investor's cost at the time of purchase,  depending upon the then-current market
value of the Fund's  assets (its interest in the  Portfolio).  Consult with your
Investment Dealer and/or  professional tax adviser with respect to the terms and
conditions for withdrawal of particular TSA Accounts and IRAs.

    Redemptions  of Shares which are not Qualified TSA  Redemptions or Qualified
IRA Redemptions,  as defined below, will be subject to the 3% Redemption Fee (in
addition to any applicable  deferred sales charge), if the Interest Rate Trigger
is active. See "EXPENSE SUMMARY" and "Shareholder Transaction Expenses" above.

QUALIFIED  TSA ACCOUNT  REDEMPTIONS  -- At any time, a redemption of Fund shares
can be effected without  assessment of the Redemption Fee, if such redemption is
a "Qualified  TSA Account  Redemption."  In general,  amounts  distributed  to a
taxpayer from a TSA Account prior to the date on which the taxpayer  reaches age
59  1/2  are  includible  in  the  taxpayer's   gross  income  and,  unless  the
distribution meets the requirements of a specific exception, are also subject to
an additional  10% penalty tax. In general,  rollovers  from a TSA Account to an
IRA and direct  trustee-to-trustee  transfers  from a TSA Account to another TSA
Account  are not  subject to tax. A  "Qualified  TSA  Account  Redemption"  is a
redemption  made by an owner of a TSA  Account  that is not subject to any early
withdrawal   penalty  tax,  other  than  a  rollover  to  an  IRA  or  a  direct
trustee-to-trustee  transfers ("Qualified  Transfers"),  unless the owner of the
TSA Account or IRA Owner continues the investment of the  transferred  amount in
the Fund.

    Owners of TSA  Accounts  requesting  a  redemption  of Fund  shares  will be
required  to provide a written  statement  as to  whether  the  proceeds  of the
redemption will be subject to the early  withdrawal  penalty tax and to identify
the specific  exception  upon which he or she intends to rely.  The  information
provided by the owner of the TSA Account  will be  reflected  on the Form 1099-R
issued to the owner and filed with the Internal  Revenue  Service in  connection
with the redemption,  as well as forming the basis for redemption as a Qualified
TSA  Account  Redemption.  The  Fund  and/or  the  Transfer  Agent  may  require
additional evidence, such as the opinion of a certified public accountant or tax
attorney, that any particular redemption will not be subject to any penalty tax.
If a qualified exception to the early withdrawal penalty, other than a Qualified
Transfer, is not identified by the TSA Account owner, the Redemption Fee will be
assessed on the  redemption if the Interest  Rate Trigger is active  (unless the
owner  continues the investment of the Fund after the  transfer).  OWNERS OF TSA
ACCOUNTS SHOULD CONSULT THEIR TAX ADVISERS REGARDING THE TAX CONSEQUENCES OF ANY
REDEMPTION.

    Some of the exceptions to the early  withdrawal  penalty taxes are described
below.  THIS  DESCRIPTION  IS  INTENDED TO PROVIDE  ONLY A BRIEF  SUMMARY OF THE
PRINCIPAL  EXCEPTIONS TO THE ADDITIONAL TAX IMPOSED ON EARLY  WITHDRAWALS  UNDER
THE CURRENT PROVISIONS OF THE CODE, WHICH MAY CHANGE FROM TIME TO TIME. THE FUND
INTENDS TO CONFORM  THE  DEFINITION  OF  QUALIFIED  TSA ACCOUNT  REDEMPTIONS  TO
CHANGES IN APPLICABLE TAX LAWS; HOWEVER, THE FUND RESERVES THE RIGHT TO CONTINUE
TO DEFINE QUALIFIED TSA ACCOUNT  REDEMPTIONS BY REFERENCE TO CODE PROVISIONS NOW
IN EFFECT OR  OTHERWISE  TO DEFINE  SUCH  PHRASE  INDEPENDENTLY  OF FUTURE  CODE
PROVISIONS.

    In general,  the early  withdrawal  penalty tax imposed by the Code will not
apply to the following types of distributions  from a TSA Account and these will
be treated as Qualified TSA Account Redemptions:

1.  Distributions  made on or  after  the date on which  the TSA  Account  owner
    attains age 59 1/2;

2.  Distributions  made to a  beneficiary  (or to the estate of the TSA  Account
    owner) on or after the death of the TSA Account owner;

3.  Distributions attributable to the TSA Account owner being disabled;

4.  Distributions  made to the TSA Account owner after  separation  from service
    after age 55;

5.  Distributions  to an alternate  payee (e.g. a former  spouse)  pursuant to a
    qualified domestic relations order;

6.  Distributions  that are part of a series  of  substantially  equal  periodic
    payments made at least annually for the life (or life expectancy) of the TSA
    Account owner, or the joint lives (or life  expectancies) of the TSA Account
    owner and his or her  designated  beneficiary,  after the TSA Account  owner
    separates from service;

7.  Distributions  made to a TSA  Account  owner for  medical  care,  but not in
    excess of the amount  allowable  as a medical  expense  deduction by the TSA
    Account owner on his or her tax return for the year;

8.  Distributions timely made to correct an excess contribution; and

9.  Distributions timely made to reduce an excess elective deferral.

QUALIFIED  IRA  REDEMPTIONS  -- At any time, a redemption  of Fund Shares can be
effected  without  assessment  of the  Redemption  Fee, if such  redemption is a
"Qualified IRA Redemption." In general, amounts distributed to a taxpayer from a
Traditional  IRA,  SEP-IRA or SIMPLE IRA prior to the date on which the taxpayer
reaches age 59 1/2 are includible in the taxpayer's gross income and, unless the
distribution meets the requirements of a specific exception, are also subject to
an  additional  10% penalty  tax.  (The  penalty is  increased  to 25% for early
withdrawals   from  SIMPLE  IRAs  that  occur  within  two  years  of  beginning
participation.)  Similar  penalties apply to early  withdrawals  from Roth IRAs,
Keogh plans and education  IRAs. In general,  rollovers  from one IRA to another
and direct  trustee-to-trustee  transfers from an IRA to another IRA (or in some
cases to other types of  qualified  plans) are not subject to tax. In  addition,
conversions of  Traditional  IRAs to Roth IRAs are subject to income tax but are
not subject to the early withdrawal penalty tax. A "Qualified IRA Redemption" is
a redemption  made by an IRA Owner to effect a distribution  from his or her IRA
account that is not subject to any early withdrawal  penalty tax, other than IRA
rollovers,  direct  trustee-to-trustee  transfers and conversions of Traditional
IRAs to Roth IRAs  ("Qualified  Transfers"),  unless the IRA Owner continues the
investment  of the  transferred  amount in the Fund.  IRA  Owners  requesting  a
redemption of Fund Shares will be required to provide a written  statement as to
whether the proceeds of the redemption  will be subject to the early  withdrawal
penalty  tax and to identify  the  specific  exception  upon which the IRA Owner
intends to rely. The information  provided by the IRA Owner will be reflected on
the Form  1099-R  issued to the IRA Owner and filed  with the  Internal  Revenue
Service in  connection  with the  redemption  as well as  forming  the basis for
redemption as a Qualified IRA  Redemption.  The Fund and/or  Transfer  Agent may
require  additional  evidence,  such  as  the  opinion  of  a  certified  public
accountant or tax attorney,  that any particular  redemption will not be subject
to any penalty  tax. If a qualified  exception to the early  withdrawal  penalty
other  than a  Qualified  Transfer  is not  identified  by the  IRA  Owner,  the
Redemption  Fee will be assessed on the  redemption if the Interest Rate Trigger
is active (unless shares of the Fund are transferred). IRA OWNERS SHOULD CONSULT
THEIR TAX ADVISERS REGARDING THE TAX CONSEQUENCES OF ANY REDEMPTION.

    Some of the exceptions to the early  withdrawal  penalty taxes are described
below.  THIS  DESCRIPTION  IS  INTENDED TO PROVIDE  ONLY A BRIEF  SUMMARY OF THE
PRINCIPAL  EXCEPTIONS TO THE ADDITIONAL TAX IMPOSED ON EARLY  WITHDRAWALS  UNDER
THE CURRENT PROVISIONS OF THE CODE, WHICH MAY CHANGE FROM TIME TO TIME. THE FUND
INTENDS TO CONFORM THE  DEFINITION  OF QUALIFIED IRA  REDEMPTIONS  TO CHANGES IN
APPLICABLE TAX LAWS; HOWEVER,  THE FUND RESERVES THE RIGHT TO CONTINUE TO DEFINE
QUALIFIED  IRA  REDEMPTIONS  BY  REFERENCE TO CODE  PROVISIONS  NOW IN EFFECT OR
OTHERWISE TO DEFINE SUCH PHRASE INDEPENDENTLY OF FUTURE CODE PROVISIONS.

TRADITIONAL IRAS,  SEP-IRAS AND SIMPLE IRAS -- In general,  the early withdrawal
penalty  tax  imposed  by the Code  will not  apply  to the  following  types of
distributions  from a Traditional IRA, SEP-IRA or a SIMPLE IRA and these will be
treated as Qualified IRA Redemptions:

1.  Distributions  made on or after the date on which the IRA Owner  attains age
    59 1/2;

2.  Distributions  made to a beneficiary  (or to the estate of the IRA Owner) on
    or after the death of the IRA Owner;

3.  Distributions attributable to the IRA Owner's being disabled;

4.  Distributions  made to the IRA Owner to the extent such distributions do not
    exceed  the  amount  of  unreimbursed  medical  expenses  allowed  as a  tax
    deduction;

5.  Distributions to unemployed  individuals to the extent such distributions do
    not exceed the amount paid for medical  insurance for the IRA Owner, and his
    or her spouse and dependents;

6.  Distributions to an IRA Owner to the extent such distributions do not exceed
    the qualified higher education expenses for the IRA Owner;

7.  Distributions  to an IRA Owner  that are used to acquire a first  home,  and
    that meet the definition of "qualified  first-time homebuyer  distributions"
    under the Code; and

8.  Distributions  that are part of a series  of  substantially  equal  periodic
    payments made at least annually for the life (or life expectancy) of the IRA
    Owner, or the joint lives (or life expectancies) of the IRA Owner and his or
    her designated beneficiary.

ROTH IRAS -- With  respect  to a Roth IRA,  all  "qualified  distributions"  are
excluded from gross income and,  therefore,  from the early  withdrawal  penalty
tax. In general,  qualified  distributions from a Roth IRA which will be treated
as Qualified IRA Redemptions include:

1.  Distributions  made on or after the date on which the IRA Owner  attains age
    59 1/2;

2.  Distributions  made to a beneficiary  (or to the estate of the IRA Owner) on
    or after the death of the IRA Owner;

3.  Distributions attributable to the IRA Owner's being disabled; and

4.  Distributions  to an IRA Owner  that are used to acquire a first  home,  and
    that meet the definition of "qualified  first-time homebuyer  distributions"
    under the Code.

    However,  a distribution  will not be a qualified  distribution,  even if it
otherwise meets the definition, if it is made within the 5-year period beginning
with the first taxable year for which the IRA Owner made a  contribution  to the
Roth IRA (or such person's  spouse made a contribution to a Roth IRA established
for the IRA  Owner).  Special  rules  apply with  respect  to  certain  types of
rollovers.

    To  the  extent  a  distribution   from  a  Roth  IRA  is  not  a  qualified
distribution,  either  because it does not meet the  definition  of a  qualified
distribution in the first  instance,  or because it is made within the five-year
period described above, the portion of the distribution that represents earnings
will be  subject  to tax under the Code,  and will also be  subject to the early
withdrawal  penalty  tax. The same  exceptions  to the penalty tax that apply to
Traditional IRAs will apply to nonqualified distributions from Roth IRAs.

    In the  event  of a  nonqualified  distribution  from a Roth  IRA,  only the
earnings  in the  account are  subject to tax;  contributions  may be  recovered
tax-free  (since no deduction is permitted  for such  contributions).  Under the
Code,   distributions   from  Roth  IRAs  are  considered  to  come  first  from
contributions,  to the extent that  distributions do not exceed the total amount
of contributions.

KEOGH PLANS -- In general,  the early withdrawal penalty tax imposed by the Code
will not apply to the following types of distributions from a Keogh plan:

1.  Distributions  made on or after the date on which the IRA Owner  attains age
    59 1/2;

2.  Distributions  made to a beneficiary  (or to the estate of the IRA Owner) on
    or after the death of the IRA Owner;

3.  Distributions attributable to the IRA Owner's being disabled;

4.  Distributions  made to the IRA Owner after separation from service after age
    55;

5.  Distributions to unemployed  individuals to the extent such distributions do
    not exceed  the amount of  unreimbursed  medical  expenses  allowed as a tax
    deduction;

6.  Distributions  to an alternate  payee (e.g., a former spouse)  pursuant to a
    qualified domestic relations order; and

7.  Distributions  that are part of a series  of  substantially  equal  periodic
    payments made at least annually for the life (or life expectancy) of the IRA
    Owner, or the joint lives (or life expectancies) of the IRA Owner and his or
    her designated beneficiary.

EDUCATION  IRAS --  Distributions  from an education  IRA are included in income
unless the qualified higher education expenses of the designated beneficiary are
equal to or greater than the amount of such distributions.  In addition, certain
special  rules  are  provided  that  permit  certain  rollovers  or  changes  in
beneficiaries.  Any  distribution  that is subject to tax under the Code is also
subject to the early withdrawal penalty tax. Thus, in general,  any distribution
from an  education  IRA that exceeds the amount of  qualified  higher  education
expenses of the designated  beneficiary  will be subject to the early withdrawal
penalty tax.

SHAREHOLDER AND FUND INFORMATION

INVESTOR  SERVICES -- The Fund provides a variety of services to help you manage
your account.  Information  Services Statements and reports that your Investment
Dealer or the Administrator may send to you include the following:

*  Confirmation  statements (which may be sent quarterly for certain  systematic
   transactions);

*  Account statements;

*  Financial reports (every six months)

    To reduce expenses,  only one copy of most financial reports will be mailed,
even if you have more than one account in the Fund. Call your Investment  Dealer
or the Security  Funds Service  Center at  1-800-888-2461  extension 3127 if you
need additional copies of financial reports.

NET ASSET VALUE -- The NAV is calculated on each day on which the New York Stock
Exchange, Inc. (the "NYSE") is open (each such day being a "Valuation Day"). The
NYSE is currently open on each day, Monday through Friday, except (a) January 1,
Martin Luther King Day,  Presidents'  Day (the third Monday in  February),  Good
Friday,  Memorial  Day (the last  Monday in May),  July 4,  Labor Day (the first
Monday in  September),  Thanksgiving  Day (the last  Thursday in  November)  and
December 25; and (b) the preceding  Friday or the subsequent  Monday when one of
the calendar-determined holidays falls on a Saturday or Sunday, respectively.

    The NAV per Share is calculated  once on each  Valuation Day as of the close
of regular trading on the NYSE (the "Valuation  Time"),  which is currently 3:00
p.m.,  Central  time,  or if the NYSE  closes  early,  at the time of the  early
closing.  The NAV per Share is  computed  by  dividing  the value of the  Fund's
assets (i.e., the value of its investment in the Portfolio and other assets,  if
any), less all liabilities,  by the total number of its Shares outstanding.  The
Portfolio's  securities  and other  assets are valued  primarily on the basis of
market quotations or, if quotations are not readily available,  by a method that
the Portfolio Trust Board believes accurately reflects fair value.

    Pursuant to procedures  adopted by the Portfolio Trust Board, the fair value
of a  Wrapper  Agreement  ("Wrapper  Value")  generally  will  be  equal  to the
difference between the Book Value and the market value (plus accrued interest on
the underlying securities) of the applicable Covered Assets. If the market value
(plus accrued  interest on the  underlying  securities) of the Covered Assets is
greater  than  their Book  Value,  the  Wrapper  Value  will be  reflected  as a
liability  of the  Portfolio in the amount of the  difference,  i.e., a negative
value,  reflecting  the  potential  liability  of the  Portfolio  to the Wrapper
Provider.  If  the  market  value  (plus  accrued  interest  on  the  underlying
securities)  of the Covered  Assets is less than their Book  Value,  the Wrapper
Value  will be  reflected  as an asset of the  Portfolio  in the  amount  of the
difference,  i.e., a positive value,  reflecting the potential  liability of the
Wrapper Provider to the Portfolio.  In performing its fair value  determination,
the Portfolio Trust Board expects to consider the  creditworthiness  and ability
of a Wrapper  Provider to pay amounts  due under the Wrapper  Agreement.  If the
Portfolio Trust Board  determines that a Wrapper Provider is unable to make such
payments,  that Board may assign a fair value to the Wrapper  Agreement  that is
less than the  difference  between  the Book  Value and the market  value  (plus
accrued interest on the underlying  securities) of the applicable Covered Assets
and the Portfolio might be unable to maintain NAV stability.

    Under  procedures  adopted  by the  Trust  Board,  an NAV  per  Share  later
determined  to have  been  inaccurate  for  any  reason  will  be  recalculated.
Purchases and redemptions  made at the NAV per Share and determined to have been
inaccurate will be adjusted,  although in certain  circumstances,  such as where
the difference  between the original NAV per Share and the  recalculated NAV per
Share  divided  by the  latter  is  0.005  (1/2 of 1%) or  less  or  shareholder
transactions are otherwise insubstantially affected, action is not required.

DIVIDENDS AND CAPITAL GAINS  DISTRIBUTIONS -- The Fund intends to distribute all
of its net investment  income and net capital gains, if any, to its shareholders
each year.  Dividends from net investment income are declared daily and are paid
monthly,  and any net capital  gains are  distributed  annually.  An  additional
annual distribution  ("Additional  Distribution") may be paid to satisfy the tax
requirements  that  the  Fund  distribute  each  year  substantially  all of its
investment company taxable income (see "Tax Considerations").

    Dividends and other distributions are automatically reinvested in additional
Shares unless the Plan participant directs otherwise.

    The Fund may declare and pay dividends in amounts which are not equal to the
amount of the net investment income it actually earns. Consequently, in any year
the amount actually  distributed may differ from the income earned.  If, for any
year, those distributions exceed the income earned, the excess may be considered
a return of capital.  On the other hand, if the income earned exceeds the amount
of the dividends  distributed,  the Fund may make an Additional  Distribution of
that excess.  To enable the Fund to maintain a stable NAV per Share in the event
of an  Additional  Distribution,  the Fund Board may  declare,  effective on the
ex-distribution  date of an  Additional  Distribution,  a  reverse  split of the
Shares in an  amount  that will  cause the total  number of Shares  held by each
shareholder,  including Shares acquired on reinvestment of that distribution, to
remain the same as before that distribution was paid.

    For example,  if the Fund declares an Additional  Distribution  of $0.10 per
Share at a time when the NAV per Share is  $10.00,  a  shareholder  holding  one
Share would receive 0.01 additional Shares on reinvestment of that distribution.
If there were no reverse split, the per Share NAV of the 1.01 Shares held by the
shareholder would be approximately  $9.90, and the aggregate value thereof would
be $10.00.  If a 1.01-for-1  reverse  Share split were  declared,  however,  the
shareholder's  holdings would be consolidated  back into one Share having an NAV
of $10.00.  Thus,  a reverse  Share split will not affect the value of the total
holdings of a shareholder.

TAX  CONSIDERATIONS  -- The Fund intends to qualify to be treated as a regulated
investment company under the Code. As a regulated  investment company,  the Fund
will not be subject to U.S. federal income tax on its investment company taxable
income  (generally  consisting  of net  investment  income and the excess of net
short-term capital gain over net long-term capital loss, if any) and net capital
gain (the  excess of net  long-term  capital  gain over net  short-term  capital
loss),  if any, that it  distributes  to its  shareholders.  The Fund intends to
distribute to its shareholders all of its investment  company taxable income and
net  capital  gain  at  least   annually,   if  necessary   through   Additional
Distributions,  and therefore does not  anticipate  incurring any federal income
tax liability.

    For Owners of TSA Accounts,  IRA Owners and Plan Participants,  the dividend
and capital gain  distributions  from the Fund  generally will not be subject to
current  taxation,  but will  accumulate on a tax-deferred  basis. To the extent
that  distributions  from a TSA,  IRA or Plan are  taxable,  they are taxable as
ordinary  income.  TSAs,  IRAs and Plans are  governed  by a complex  set of tax
rules.  Owners of TSA Accounts,  IRA Owners and Plan Participants should consult
with a professional tax adviser  regarding the tax consequences  associated with
an investment in the Fund.

PERFORMANCE  -- The  Fund's  performance  may be  used  from  time  to  time  in
advertisements,  shareholders reports or other communications to shareholders or
prospective shareholders.  In accordance with SEC regulations,  Fund performance
may be  calculated  with or  without  deduction  of the  maximum  sales  charge.
However, any performance information shown without deduction of the sales charge
would be lower if the sales charge had been  deducted.  Performance  information
may include  investment  results and/or comparisons of its investment results to
the IBC Averages,  Lipper Averages, an appropriate  guaranteed interest contract
average,  or other various unmanaged indices or results of other mutual funds or
investment  or  saving  vehicles.  The  Portfolio's  strategies,   holdings  and
performance will be detailed twice a year in the Fund's financial reports, which
are sent to all Fund shareholders.

    Mutual fund  performance is commonly  measured as total return and/or yield.
The  performance  of a class of shares is affected by its expenses and its share
of those expenses of the Portfolio.

EXPLANATION  OF  PERFORMANCE  TERMS -- Total Return is the change in value of an
investment  in the Shares  over a given  period,  assuming  reinvestment  of any
dividends and capital gain  distributions.  A cumulative  total return  reflects
actual  performance over a stated period of time. An average annual total return
is a hypothetical rate of return that, if achieved annually, would have produced
the same  cumulative  total return if  performance  had been  constant  over the
entire period. Average annual total return calculations smooth out variations in
performance;  they  are not the same as  actual  year-by-year  results.  Average
annual  total  returns  covering  periods  of less  than  one year  assume  that
performance will remain constant for the rest of the year.

    Yield refers to the income  generated by an  investment in the Shares over a
given  period  of time,  expressed  as an annual  percentage  rate.  Yields  are
calculated  according  to a  standard  that is  required  for all stock and bond
funds.  Because this differs from other accounting methods, the quoted yield may
not equal the income actually paid to shareholders.

    In accordance with SEC regulations,  the yield of the Fund (the "SEC Yield")
shall be calculated on any determination date as follows:

                            2[((a-b)/c*d) + 1)^6 - 1]

a = Current income measured over a 30-day period

b = Expenses accrued during the same 30-day period

c = Average daily number of shares outstanding during the same 30-day period

d = Maximum offering price per share on the last day of the period.

    The "Annual  Effective Yield of the Fund" is intended to represent one day's
investment income expressed as an annualized yield and compounded annually.  The
Annual  Effective  Yield of the Fund  shall be  expressed  as a  percentage  and
calculated on each  business day as follows  based on the dividend  declared for
the previous day:

                   [(1 + PREVIOUS DAY'S DIVIDEND FACTOR)^365-1]
                   --------------------------------------------
                                  NAV Per Share

    EXAMPLE:  If on March 1 the Fund's  Dividend  Factor is  0.00174163  and the
Fund's NAV per share is $10, then the Fund's Annual  Effective Yield for March 2
equals 6.56%.

    The "Annual  Effective  Yield of the Portfolio" is intended to represent the
previous day's  investment  income of the Portfolio,  expressed as an annualized
yield and compounded annually.

    The  "Annual  Effective  Yield of the  Portfolio"  shall be  expressed  as a
percentage  and calculated on each Business Day as follows based on the dividend
declared for the previous day:

             [(1 + PREVIOUS DAY'S PORTFOLIO DIVIDEND FACTOR)^365-1]
             ------------------------------------------------------
                                  NAV Per Share

    Once the Interest  Rate Trigger is active,  it shall remain active every day
until the Reference  Index Yield is less than the Annual  Effective Yield of the
Portfolio plus 1.55%, at which time the Interest Rate Trigger  becomes  inactive
on the following day and remains  inactive every day thereafter until it becomes
active again.

    EXAMPLE: If on March 1 the Portfolio's Dividend Factor is 0.00174163 and the
Portfolio's  NAV per share is $10, then the Portfolio's  Annual  Effective Yield
for March 2 equals 6.56%.

    The Annual  Effective Yield of the Portfolio is used in determining when the
Interest Rate Trigger is active, as discussed in "Shareholder Fees," on page 4.

    Performance  information or  advertisements  may include  comparisons of the
Shares'  investment  results  to various  unmanaged  indices or results of other
mutual funds or investment or savings  vehicles.  From time to time, the Shares'
ranking may be quoted from various sources,  such as Lipper Analytical Services,
Inc., Value Line, Inc. and Morningstar, Inc.

    Unlike some bank deposits or other  investments that pay a fixed yield for a
stated period of time,  the total return of the Shares will vary  depending upon
interest  rates,  the current  market value of the Portfolio  Securities and the
value of the Wrapper  Agreements  and changes in the  expenses of the Shares and
the Portfolio. In addition, during certain periods for which total return may be
provided,  the Fund's  administrator  and Transfer  Agent,  Security  Management
Company,  LLC ("SMC") may have voluntarily agreed to waive portions of its fees,
or to reimburse  certain  operating  expenses of the Fund. In addition,  Bankers
Trust may have agreed to do the same with respect to the Portfolio. Such waivers
will have the effect of  increasing  the Fund's net income  (and  therefore  its
yield and total return) during the period such waivers are in effect.

    TOTAL RETURNS AND YIELDS ARE BASED ON PAST RESULTS AND ARE NOT AN INDICATION
OF FUTURE PERFORMANCE.

MANAGEMENT OF THE FUND

BOARDS OF DIRECTORS  -- The Fund's  business and affairs are governed by a Board
of Directors.  See "Management of the Fund" in the SAI for more information with
respect to the Directors and officers of the Fund.

INVESTMENT  ADVISER -- The Fund has not retained  the services of an  investment
adviser because it seeks to achieve its investment objective by investing all of
its Assets in the Portfolio.  The Portfolio has retained the services of Bankers
Trust as its investment  adviser  pursuant to an Investment  Advisory  Agreement
between  the  Portfolio  Trust and  Bankers  Trust  dated  April  28,  1993 (the
"Investment Advisory Agreement").

    Bankers  Trust,  subject to the  supervision  and direction of the Portfolio
Trust's  Board,  manages  the  Portfolio  in  accordance  with  the  Portfolio's
investment objective and stated investment policies,  makes investment decisions
for the  Portfolio,  places  orders to purchase  and sell  securities  and other
financial  instruments  on  behalf of the  Portfolio  and  employs  professional
investment managers and securities analysts who provide research services to the
Portfolio.  Bankers  Trust may utilize  the  expertise  of any of its  worldwide
subsidiaries and affiliates to assist it in its role as investment adviser.  All
orders for  investment  transactions  on behalf of the  Portfolio  are placed by
Bankers Trust with  broker-dealers  and other financial  intermediaries  that it
selects,  including  those  affiliated  with  Bankers  Trust.  A  Bankers  Trust
affiliate  will be used in  connection  with a purchase or sale of an investment
for the Portfolio only if Bankers Trust believes that the affiliate's charge for
the transaction does not exceed usual and customary  levels.  The Portfolio will
not invest in obligations, including Wrapper Agreements, for which Bankers Trust
or any  of its  affiliates  is the  ultimate  obligor  or  accepting  bank.  The
Portfolio  may,  however,  invest  in  the  obligations  of  correspondents  and
customers of Bankers Trust.

THE INVESTMENT  ADVISORY AGREEMENT -- The Investment Advisory Agreement provides
for the  Portfolio  Trust to pay  Bankers  Trust a fee,  accrued  daily and paid
monthly,  equal to  0.70%  per  year of the  average  daily  net  assets  of the
Portfolio.  Bankers Trust has indicated that it will  voluntarily  waive all but
0.42% of this fee.

    Bankers Trust has been advised by its counsel  that,  in counsel's  opinion,
Bankers Trust currently may perform the services for the Portfolio  described in
this Prospectus and the SAI without violation of the Glass-Steagall Act or other
applicable banking laws or regulations. State laws on this issue may differ from
the   interpretations   of  relevant   federal  law,  and  banks  and  financial
institutions may be required to register as dealers pursuant to state securities
law.

ADMINISTRATOR -- Under an Administration  Services and Transfer Agency Agreement
with  Security  Income  Fund,  Security  Management  Company,  LLC ("SMC" or the
"Administrator")   is  responsible  for  calculating  the  Fund's  NAV  and  for
performing  the  bookkeeping,  accounting and transfer  agency  function for the
Fund. This Agreement  provides for the Fund to pay SMC a fee,  accrued daily and
paid  monthly,  equal to .09% per year of the  average  daily net  assets of the
Fund.  For its transfer  agency  services SMC receives $8 per account and $1 per
dividend and other  transactions.  SMC is a limited  liability company organized
under the laws of the State of Kansas and is owned by its member firms, Security
Benefit Life Insurance  Company and Security Benefit Group, Inc. SMC's principal
offices are located at 700 SW Harrison, Topeka, Kansas 66636-0001.

    Under a  Sub-Accounting  Agreement  between SMC and Bankers  Trust,  Bankers
Trust has agreed to provide certain accounting  services to the Fund,  including
the daily calculation of the Fund's NAV. The  Sub-Accounting  Agreement provides
for SMC to pay Bankers Trust a fee, equal to $14,000 per year.

    Pursuant to a separate  Management  Services  Agreement,  SMC also  performs
certain  other  services  on behalf  of the  Fund.  Under  this  Agreement,  SMC
provides, among other things, feeder fund management and administrative services
to  the  Fund  which  include  monitoring  the  performance  of  the  Portfolio,
coordinating the Fund's relationship with the Portfolio,  communicating with the
Fund's Board of Directors and shareholders regarding the Portfolio's performance
and the  Fund's  two tier  structure,  and in  general,  assisting  the Board of
Directors of the Fund in all aspects of the  administration and operation of the
Fund. For these services,  the Fund pays SMC a fee at the annual rate of .20% of
its average daily net assets, calculated daily and payable monthly.

    Under an Administration  and Services and Transfer Agency Agreement with the
Portfolio Trust, Bankers Trust calculates the NAV of the Portfolio and generally
assists the Portfolio in all aspects of the  administration and operation of the
Portfolio. This Administration and Services Agreement provides for the Portfolio
to pay Bankers Trust a fee,  accrued daily and paid monthly,  equal to 0.05% per
year of the Portfolio's average daily net assets.  Under this Administration and
Services   Agreement,   Bankers   Trust  may   delegate   one  or  more  of  its
responsibilities  to others,  including  the  Distributor,  at  Bankers  Trust's
expense.

    Subject to  certain  conditions,  SMC may,  out of its own  resources,  make
ongoing  payments to  brokerage  firms,  plan  administrators  and  fiduciaries,
financial institutions (including banks) and other entities for certain services
provided to the Fund and/or shareholders.

DISTRIBUTOR -- Security Distributors, Inc., as distributor, serves as the Fund's
principal underwriter. Security Distributors, Inc. is a registered broker/dealer
and is a wholly-owned  subsidiary of Security Benefit Group,  Inc. Its principal
offices are at 700 SW Harrison, Topeka, Kansas 66636-0001.

CUSTODIAN  -- UMB  Bank,  n.a.  acts as  custodian  for the  assets of the Fund.
Bankers  Trust  acts as  custodian  for the  assets of the  Portfolio  under the
Administration  and  Services  Agreement  with the Trust.  It is not  separately
compensated  for this  service and may,  at its own  expense,  delegate  certain
services to other qualified entities.

YEAR 2000  COMPLIANCE -- Like other mutual funds, as well as other financial and
business organizations around the world, the Fund could be adversely affected if
the computer systems used by the Administrator, Bankers Trust, and other service
providers,  in performing their management and  administrative  functions do not
properly process and calculate date-related  information and data before, during
and after January 1, 2000. Some computer software and hardware systems currently
cannot  distinguish  between  the year 2000 and the year 1900 or some other date
because of the way date fields were encoded. This is commonly known as the "Year
2000  Problem."  If not  addressed,  the Year  2000  Problem  could  impact  the
management,  transfer agency, accounting, custody and other services provided to
the Fund by the Administrator, Bankers Trust and other service providers.

    The  Administrator  has  adopted  a plan to be "Year  2000  Compliant"  with
respect to both its  internally  built  systems as well as systems  provided  by
external  vendors.  The  Administrator  considers a system "Year 2000 Compliant"
when it is able to correctly process, provide and/or receive data before, during
and after the Year 2000. The Administrator's  overall approach to addressing the
Year 2000  Problem is as follows:  (1) to  inventory  its  internal and external
hardware,  software,  telecommunications and data transmissions to customers and
conduct a risk  assessment with respect to the impact that a failure of any such
system  would have on its  business  operations;  (2) to modify or  replace  its
internal  systems and obtain vendor  certifications  of Year 2000 compliance for
systems  provided  by  vendors or replace  such  systems  that are not Year 2000
Compliant;  and (3) to implement and test its systems for Year 2000  compliance.
The  Administrator  has  completed  the  inventory  of its internal and external
systems   and   has   made   substantial    progress   toward   completing   the
modification/replacement  of its internal systems,  as well as towards obtaining
Year 2000 Compliant  certifications  from its external vendors.  Overall systems
testing is  scheduled  to commence in December  1998 and is  scheduled to extend
into the first six months of 1999.  In addition,  the Fund has been  informed by
Bankers Trust that it is working both internally and with its business  partners
and service providers to address the Year 2000 Problem.

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

    The Year 2000 Problem is also expected to impact operating companies,  which
may include issuers of portfolio  securities  held by the Portfolio,  to varying
degrees based upon various factors, including, but not limited to, the company's
industry sector and degree of technological sophistication. The Fund and Bankers
Trust are unable to predict what impact, if any, the Year 2000 Problem will have
on issuers of the portfolio securities held by the Portfolio and, indirectly, on
the value of the Fund's shares.

EXCHANGE PRIVILEGE -- Shareholders who own shares of the Fund may exchange those
shares for shares of another of the series of Security Income Fund or for shares
of other mutual funds  distributed by the  Distributor  (the "Security  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, Class B and Class C shares of the Fund may
be  exchanged  for  Class  A,  Class  B and,  if  applicable,  Class  C  shares,
respectively, of another Security Fund. Any applicable contingent deferred sales
charge will be calculated  from the date of the initial  purchase.  Exchanges of
Class A shares are made at net asset value without a front-end  sales charge.  A
Redemption  Fee  may be  assessed  on an  exchange  from  the  Security  Capital
Preservation  Fund to another  Security  Fund if the  Interest  Rate  Trigger is
active.

    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   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  Fund  upon  60  days'  notice  to
shareholders.  A current  prospectus of the Security Fund into which an exchange
is made will be given to each shareholder exercising this privilege.

ADDITIONAL INFORMATION ABOUT THE FUND

The Fund is a mutual fund:  an  investment  that pools  shareholders'  money and
invests  it  toward a  specified  goal.  The Fund is a  separate  series  of the
Security  Income  Fund  organized  under  the  laws of the  State of  Kansas  on
September 9, 1970. The Portfolio is a separate  subtrust of the Portfolio Trust,
a New York master trust fund organized  pursuant to a Declaration of Trust dated
March 27, 1993.

    The  Fund  and  the  Trust  each  reserves  the  right  to  add   additional
series/subtrusts in the future. 

    The  Articles of  Incorporation  of Security  Income Fund  provides  for the
issuance  of an  indefinite  numberof  shares  of  capital  stock in one or more
classes or series.

    Security  Income Fund has authorized  capital stock of $1.00 par value.  Its
shares are  currently  issued in eight  series,  Corporate  Bond  Fund,  Limited
Maturity Bond Fund,  U.S.  Government  Fund, High Yield Fund,  Emerging  Markets
Total Return Fund,  Global Asset Allocation Fund, Global High Yield Fund and the
Capital  Preservation  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.

    Security Income Fund currently  issues two classes of shares for each of its
eight series,  except  Capital  Preservation  Fund which offers three classes of
shares.  Each  class  of  shares  participates  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  Fund's  shares  will be  fully  paid and
nonassessable  by the Fund.  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.  Under
certain  circumstances,  the  shareholders of one series of Security Income Fund
could  control  the  outcome  of these  votes.  On  other  matters  affecting  a
particular series, such as 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 Fund does not generally hold annual meetings of shareholders and will do
so only when required by law.  Shareholders  may remove directors from office by
votes  cast in person or by proxy at a meeting of  shareholders.  Such a meeting
will be called at the written  request of the holders of 10% of Security  Income
Fund's outstanding shares.

    Each subtrust of the Portfolio  Trust,  including the  Portfolio,  will vote
separately on any matter  involving that  subtrust.  Holders of interests in all
the  subtrusts of the  Portfolio  Trust,  however,  will vote  together to elect
Trustees of the Portfolio Trust and for certain other matters.  The subtrusts of
the  Portfolio  Trust will vote  together or  separately  on matters in the same
manner,  and in the same  circumstances,  as do the series of the Fund.  As with
Security  Income Fund,  the investors in one or more  subtrusts of the Portfolio
Trust could  control the outcome of these  votes.  No subtrust of the  Portfolio
Trust has any preference over any other subtrust.

    The Portfolio  Trust was organized as a trust under the laws of the State of
New York. The Portfolio Trust's  Declaration of Trust provides that the entities
investing in the  Portfolio  (e.g.,  investment  companies  such as the Fund and
common and  commingled  trust funds) will each be liable for all  obligations of
the  Portfolio.  However,  the risk of the Fund's  incurring  financial  loss on
account of such liability is limited to  circumstances  in which both inadequate
insurance  existed and the Portfolio  itself was unable to meet its obligations.
Accordingly,  the  Directors  of the Fund  believe that neither the Fund nor its
shareholders will be adversely affected by reason of the Fund's investing in the
Portfolio.

INFORMATION CONCERNING THE MASTER FEEDER FUND STRUCTURE

Unlike other mutual funds that  directly  acquire and manage their own portfolio
securities,  the Fund seeks to achieve its investment objective by investing all
of its Assets in the Portfolio,  a separate subtrust of a registered  investment
company  with the same  investment  objective  as the  Fund.  Therefore,  a Fund
shareholder's  interest in the  Portfolio's  assets is indirect.  In addition to
selling a beneficial  interest to the Fund,  the Portfolio  may sell  beneficial
interests to other mutual funds or institutional investors.  Such investors will
invest  in the  Portfolio  on the  same  terms  and  conditions  and  will pay a
proportionate share of the Portfolio's  expenses.  However,  the other investors
investing  in the  Portfolio  are not  required  to sell  their  shares or other
interests at the same public  offering  price as the Fund,  due to variations in
sales commissions and other operating expenses. Therefore, investors in the Fund
should be aware that these  differences  may  result in  differences  in returns
experienced by investors in the different entities that invest in the Portfolio.
Such  differences  in returns are also present in other mutual fund  structures.
Information  concerning other holders of interests in the Portfolio is available
from Bankers Trust, as the Administrator of the Portfolio, at 1-800-677-7596.

    The master-feeder  structure is relatively  complex,  so shareholders should
carefully consider this investment approach.  Smaller investors in the Portfolio
may be materially  affected by the actions of larger investors in the Portfolio.
For example,  if a large investor  withdraws  from the Portfolio,  the remaining
investors may experience higher pro rata operating  expenses,  thereby producing
lower  returns  (however,  this  possibility  exists  as well for  traditionally
structured  funds that have large  investors).  Additionally,  the Portfolio may
become less diverse, resulting in increased portfolio risk. Also, investors with
a greater  pro rata  ownership  in the  Portfolio  could have  effective  voting
control of its operations.  Except as permitted by the SEC, whenever the Fund is
requested to vote on matters  pertaining to the Portfolio,  the Fund will hold a
meeting of  shareholders  of the Fund and will cast all of its votes in the same
proportion as the votes of the Fund's shareholders. Fund shareholders who do not
vote will not affect the Fund's  votes on the  Portfolio's  matters;  the Fund's
votes  representing  Fund shareholders not voting will be voted by the Directors
or officers of the Fund in the same proportion as the Fund  shareholders who do,
in fact, vote. Certain changes in the Portfolio's investment objective, policies
or restrictions  may require the Fund to withdraw its interest in the Portfolio.
Any such withdrawal could result in a distribution "in kind" of Portfolio assets
(as  opposed to a cash  distribution  from the  Portfolio).  If  securities  are
distributed,  the Fund could incur brokerage, tax or other charges in converting
the securities to cash. In addition,  the  distribution  in kind may result in a
less  diversified  portfolio of investments or adversely affect the liquidity of
the  Fund.  Notwithstanding  the  above,  there  are  other  means  for  meeting
redemption  requests,  such as borrowing.  The Fund may withdraw its  investment
from the  Portfolio at any time,  if the Board of  Directors of Security  Income
Fund (the  "Fund  Board")  determines  that it is in the best  interests  of the
shareholders  of the Fund to do so.  Upon any such  withdrawal,  the Fund  Board
would  consider what action might be taken,  including the investment of all the
assets  of the  Fund  in  another  pooled  investment  entity  having  the  same
investment  objective as the Fund or the retaining of an  investment  adviser to
manage the Fund's assets in accordance  with the investment  policies  described
herein with respect to the Portfolio.

DEFINITIONS OF SECURITIES PURCHASED BY THE PORTFOLIO

ASSET-BACKED    SECURITIES   --   Asset-backed    securities   have   structural
characteristics similar to mortgage-backed  securities.  However, the underlying
assets are not first lien mortgage loans or interests therein but include assets
such as  motor  vehicle  installment  sale  contracts,  other  installment  sale
contracts,  home  equity  loans,  leases of various  types of real and  personal
property,  and receivables from revolving credit (credit card) agreements.  Such
assets  are   securitized   through  the  use  of  trusts  or  special   purpose
corporations.   Payments  or   distributions   of  principal   and  interest  on
asset-backed  securities  may be  guaranteed  up to  certain  amounts  and for a
certain time period by a letter of credit or a pool insurance policy issued by a
financial institution unaffiliated with the issuer, or other credit enhancements
may be present.

    Asset-backed  securities  present  certain  risks that are not  presented by
mortgage-backed securities.  Primarily, these securities do not have the benefit
of the same type of security  interest in the  related  collateral.  Credit card
receivables  are  generally  unsecured,  and the  debtors  are  entitled  to the
protection of a number of state and federal  consumer credit laws, many of which
give such  debtors  the right to avoid  payment of certain  amounts  owed on the
credit cards,  thereby reducing the balance due. There is the risk in connection
with automobile  receivables that recoveries on repossessed  collateral may not,
in some cases, be available to support payments on those securities.

COLLATERALIZED  MORTGAGE  OBLIGATIONS  -- CMOs are  mortgage-backed  bonds  that
separate mortgage pools into different  classes,  called tranches.  Tranches pay
different rates of interest and can mature in a few months,  or in as long as 20
years.  Issued by the Federal Home Loan Mortgage  Corporation  (Freddie Mac) and
private  issuers,  CMOs are  usually  backed by  government-guaranteed  or other
top-grade  mortgages  and have AAA ratings.  In return for a lower  yield,  CMOs
provide  investors  with  increased  security   throughout  the  life  of  their
investment compared to purchasing a whole mortgage-backed  security. Even so, if
mortgage rates drop sharply,  causing a flood of refinancings,  prepayment rates
will soar and CMO tranches will be repaid before their  expected  maturity.  See
also REMICs, below.

MORTGAGE-BACKED   SECURITIES  --  The  Portfolio  may  purchase  mortgage-backed
securities issued by the U.S. government,  its agencies or instrumentalities and
non-governmental  entities such as banks,  mortgage  lenders or other  financial
institutions.   Mortgage-backed   securities   include   mortgage   pass-through
securities,   mortgage-backed  bonds  and  mortgage  pay-through  securities.  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.  A  mortgage-backed  bond is a general  obligation  of the
issuer,  payable out of the issuer's general funds and additionally secured by a
first  lien on a pool of  mortgages.  Mortgage  pay-through  securities  exhibit
characteristics  of both  pass-through and  mortgage-backed  bonds. The mortgage
pass-through  securities  issued  by  non-governmental  entities  such as banks,
mortgage  lenders or other  financial  institutions  in which the  Portfolio may
invest include private label mortgage  pass-through  securities and whole loans.
Mortgage-backed  securities  also  include  other  debt  obligations  secured by
mortgages on commercial  real estate or residential  properties.  Other types of
mortgage-backed  securities  will likely be  developed  in the  future,  and the
Portfolio may invest in them if Bankers  Trust  determines  they are  consistent
with the Portfolio's investment objective and policies.

    Unlike ordinary Fixed Income Securities, which generally pay a fixed rate of
interest and return  principal upon maturity,  mortgage-backed  securities repay
both interest income and principal as part of their periodic  payments.  Because
the mortgages underlying mortgage-backed certificates can be prepaid at any time
by homeowners or corporate  borrowers,  mortgage-backed  securities give rise to
certain  unique  "pre-payment"  risks.  Prepayment  risk  or  call  risk  is the
likelihood that, during periods of falling interest rates,  securities with high
stated interest rates will be prepaid (or "called") prior to maturity, requiring
the Portfolio to invest the proceeds at generally lower interest rates.

REAL ESTATE MORTGAGE  INVESTMENT  CONDUITS -- REMICs are  pass-through  vehicles
created  under the tax  reform act of 1986 to issue  multiclass  mortgage-backed
securities.  REMICs may be organized as  corporations,  partnerships  or trusts.
Interests  in REMICs  may be senior or junior,  regular  (DEBT  INSTRUMENTS)  or
residual  (equity  interests).  CMOs  (described  above)  normally have AAA bond
ratings, whereas REMICs represent a range of risk levels.

REPURCHASE  AGREEMENTS  -- In a  repurchase  agreement,  the  Portfolio  buys  a
security at one price and simultaneously agrees to sell it back to the seller on
a specific  date and at a higher  price  reflecting  a market  rate of  interest
unrelated to the coupon rate or maturity of the underlying  security.  Delays or
losses  could  result if the other  party to the  agreement  defaults or becomes
insolvent.

REVERSE  REPURCHASE  AGREEMENTS  AND  DOLLAR  ROLLS -- In a  reverse  repurchase
agreement,  the  Portfolio  temporarily  transfers  possession  of  a  portfolio
instrument to another party in return for cash.  This could increase the risk of
fluctuation  in the Fund's  yield or in the market  value of its interest in the
Portfolio.  In a dollar  roll,  the  Portfolio  sells  mortgage-backed  or other
securities  for delivery in the current  month and  simultaneously  contracts to
purchase  substantially  similar  securities on a specified future date. Reverse
repurchase  agreements  and  dollar  rolls  are forms of  borrowing  and will be
counted towards the Portfolio's borrowing  restrictions.  See "Borrowing" on the
following pages and in the SAI. Wrapper Agreements would cover the cash proceeds
of such  transactions but not the portfolio  instruments  transferred to another
party until possession of such instruments is returned to the Portfolio.

RULE  144A  SECURITIES  -- Rule  144A  Securities  are  securities  that are not
registered  for sale  under  the  federal  securities  laws but can be resold to
institutions  pursuant to Rule 144A under the Securities  Act of 1933.  Provided
that a dealer or institutional  trading market in such securities exists,  these
restricted  securities are treated as exempt from the  Portfolio's  15% limit on
illiquid securities. Under the supervision of the Portfolio Trust Board, Bankers
Trust  determines the liquidity of restricted  securities;  and through  reports
from Bankers  Trust,  the Portfolio  Trust Board  monitors  trading  activity in
restricted securities. If institutional trading in restricted securities were to
decline, the liquidity of the Portfolio could be adversely affected.

SHORT-TERM INVESTMENTS -- The Portfolio's assets may be invested in high quality
short-term investments with remaining maturities of 397 days or less to maintain
the  Liquidity  Reserve,  to  meet  anticipated  redemptions  and  expenses  for
day-to-day  operating  purposes  and when,  in Bankers  Trust's  opinion,  it is
advisable to adopt a temporary defensive position because of unusual and adverse
conditions affecting the respective markets.

U.S. GOVERNMENT  SECURITIES -- U.S. government  securities are high-quality debt
securities  issued  or  guaranteed  by the  U.S.  Treasury  or by an  agency  or
instrumentality of the U.S. government.  Not all U.S. government  securities are
backed  by the  full  faith  and  credit  of the  United  States.  For  example,
securities  issued by the Farm Credit Banks or by the FNMA are  supported by the
instrumentality's  right to borrow money from the U.S.  Treasury  under  certain
circumstances.  However,  securities  issued by certain  other U.S.  agencies or
instrumentalities  are  supported  only by the credit of the entity  that issued
them.

OTHER U.S.  DOLLAR-DENOMINATED  FIXED INCOME  SECURITIES -- Bonds and other debt
instruments are used by issuers to borrow money from investors.  The issuer pays
the  investor a fixed or  variable  rate of  interest  and must repay the amount
borrowed at maturity.  Some debt  securities,  such as zero coupon bonds, do not
pay current  interest but are  purchased  at a discount  from their face values.
Debt securities, loans and other direct debt have varying degrees of quality and
varying levels of sensitivity to changes in interest  rates.  Longer-term  bonds
are generally more sensitive to interest rate changes than short-term bonds.

U.S. DOLLAR-DENOMINATED FOREIGN SECURITIES -- The Portfolio may invest a portion
of its assets in the  dollar-denominated  debt securities of foreign  companies.
Investing  in the  securities  of  foreign  companies  involves  more risks than
investing in  securities of U.S.  companies.  Their value is subject to economic
and political  developments in the countries where the companies  operate and to
changes in foreign currency  values.  Values may also be affected by foreign tax
laws,  changes  in foreign  economic  or  monetary  policies,  exchange  control
regulations  and  regulations  involving  prohibitions  on the  repatriation  of
foreign currencies.

    In general,  less information may be available about foreign  companies than
about U.S.  companies,  and foreign  companies  are generally not subject to the
same  accounting,  auditing  and  financial  reporting  standards  as  are  U.S.
companies.  Foreign  securities  markets  may be less liquid and subject to less
regulation than the U.S. securities markets.  The costs of investing outside the
United States frequently are higher than those in the United States. These costs
include relatively higher brokerage commissions and foreign custody expenses.

U.S.  DOLLAR-DENOMINATED  SOVEREIGN AND SUPRANATIONAL FIXED INCOME SECURITIES --
Debt  instruments  issued or  guaranteed  by foreign  governments,  agencies and
supranational organizations ("sovereign debt obligations"), especially sovereign
debt obligations of developing countries, may involve a high degree of risk. The
issuer of the  obligation  or the  governmental  authorities  that  control  the
repayment of the debt may be unable or unwilling to repay principal and interest
when due and may require  renegotiation  or  rescheduling  of debt payments.  In
addition,  prospects  for  repayment  of  principal  and  interest may depend on
political as well as economic factors.

WHEN-ISSUED  AND DELAYED  DELIVERY  SECURITIES  -- The  Portfolio  may  purchase
securities on a when-issued or delayed  delivery basis.  Delivery of and payment
for these securities may take place as late as a month or more after the date of
the  purchase  commitment.  The value of these  securities  is subject to market
fluctuations  during this period,  and no income accrues to the Portfolio  until
settlement takes place.

ZERO COUPON SECURITIES -- Zero Coupon Securities  including CATS, TIGRs and TRs,
are the separate  income or principal  components  of a debt  instrument.  These
involve risks that are similar to those of other debt securities,  although they
may be more volatile,  and the value of certain zero coupon  securities moves in
the same  direction  as interest  rates.  Zero coupon  bonds do not make regular
interest payments.
<PAGE>
REDUCED SALES CHARGES

CLASS A SHARES -- Initial sales charges may be reduced or eliminated for persons
or  organizations  purchasing Class A shares of the Fund 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  or a  Statement  of  Intention,  the term
"Purchaser" includes the following persons: 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 a Fund, a Purchaser  may combine all  previous  purchases of the Funds 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 the Funds, and other Security Funds,  except Security Cash
Fund, in those states where shares of the fund being purchased are qualified for
sale.

STATEMENT  OF  INTENTION  -- A  Purchaser  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 the Funds,  and other
Security Funds,  except Security Cash 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.  Shares  equal to five  percent  (5%) of the amount  specified in the
Statement of Intention  will be held in escrow 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.

    A  Statement  of  Intention  may be revised  during  the  13-month  (or,  if
applicable,  36-month) period. A Statement of Intention may be obtained from the
Fund.

REINSTATEMENT  PRIVILEGE -- Shareholders  who redeem their Class A shares of the
Funds have a one-time  privilege (1) to reinstate  their  accounts by purchasing
Class A 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  Class A shares of another of the Security
Funds,  without  a  sales  charge  up to the  dollar  amount  of the  redemption
proceeds. To exercise this privilege,  a shareholder must provide written notice
and a check in the  amount of the  reinvestment  within  thirty  days  after the
redemption request; the reinstatement will be made at the net asset value on the
date received by the Fund or the Security Funds, as appropriate.

ADDITIONAL INFORMATION ABOUT TSAS

TSA Accounts must generally be provided under a plan which meets certain minimum
participation,  coverage, and nondiscrimination  requirements.  TSA Accounts are
subject to minimum distribution  requirements such that an employees interest in
a TSA Account must generally be distributed or begin to be distributed not later
than April 1 of the calendar  year  following  the later of the calendar year in
which they employee reaches age 70 1/2 or retires.

    TSA  Accounts  may  be  purchased  with  employer  contributions,   employee
contributions or a combination of both. An employee's rights under a TSA Account
must  be   nonforfeitable.   Numerous   limitations   apply  to  the  amount  of
contributions  that may be made to a TSA  Account.  The  applicable  limit  will
depend  upon,  among other  things,  whether the TSA Account is  purchased  with
employer or employee contributions.

    Amounts used to purchase a TSA Account  generally  are  excludable  from the
taxable  income  of the  employee.  As a  result,  all  distributions  from such
accounts are normally taxable in full as ordinary income to the employee.

    TSA  Accounts  must  prohibit  the  distribution  of employee  contributions
(including  earnings  thereon) until the employee:  (i) attains age 59 1/2; (ii)
terminates  employment,  (iii)  dies;  (iv)  becomes  disabled;  or  (v)  incurs
financial hardship (earnings may not be distributed in the event of hardship).

TYPES OF INDIVIDUAL RETIREMENT ACCOUNTS

TRADITIONAL IRAS -- If you are under age 70 1/2, and you (or if you file a joint
return, your spouse) have taxable compensation, you may set up a Traditional IRA
and make  annual  IRA  contributions  of up to $2,000,  or 100% of your  taxable
compensation,  whichever is less. Taxable income includes wages,  salaries,  and
other  amounts  reported  in  box 1 of  Form  W-2,  as  well  as  earnings  from
self-employment.  If you file a joint  return and your taxable  compensation  is
less  than  that  of  your  spouse,  you  may  make  annual  contributions  to a
Traditional  IRA equal to the lesser of $2,000,  or the sum of (i) your  taxable
compensation  and (ii) the taxable  compensation of your spouse,  reduced by the
amount of his or her IRA deduction for the year.

    Amounts  contributed  to a  Traditional  IRA generally  are  deductible  for
federal  income  tax  purposes.  However,  if you were  covered  by an  employer
retirement  plan, the amount of your  contribution to a Traditional IRA that you
may deduct will be reduced or eliminated if your modified  adjusted gross income
exceeds certain amounts  (currently  $50,000 for a married couple filing a joint
return  and  $30,000  for a single  taxpayer).  If your  spouse is covered by an
employer  retirement  plan  but you are  not,  you  may be able to  deduct  your
contributions  to a Traditional IRA;  however,  the deduction will be reduced or
eliminated if your  adjusted  gross income on a joint return  exceeds  $150,000.
Even if your ability to deduct  contributions  to a Traditional  IRA is limited,
you may still make contributions up to the limits described above.

    In  general,  you may  also  make a  contribution  to a  Traditional  IRA by
"rolling over" all or a portion of a  distribution  you receive from a qualified
retirement plan (such as a pension or  profit-sharing  plan or a 401(k) plan) or
another Traditional IRA. Amounts distributed from a Traditional IRA and eligible
rollover distributions from qualified retirement plans will not be includible in
income if they are  contributed to a Traditional  IRA in a rollover  transaction
which  meets  certain  conditions;  however,  a federal  withholding  tax may be
imposed on such distributions.  Consult your tax adviser for complete details on
Traditional IRAs.

ROTH IRAS --  Regardless  of your age,  you may be able to establish a Roth IRA.
Contributions  to Roth IRAs are not  deductible for federal income tax purposes.
However, if all of the applicable  requirements are met, earnings in the account
accumulate tax free, and all withdrawals are also tax free.  Generally,  you may
contribute  up to  $2,000  annually  to a Roth IRA;  however,  your  ability  to
contribute to a Roth IRA will be reduced or  eliminated  if your adjusted  gross
income exceeds certain amounts (currently $150,000 for a married couple filing a
joint  return and  $95,000  for a single  taxpayer).  In  addition,  if you make
contributions to both a Traditional IRA and a Roth IRA, your contribution  limit
for the Roth IRA will be reduced by the amount of the  contribution  you make to
the Traditional IRA.

    If certain requirements are met, and (i) your modified adjusted gross income
is not more than $100,00, and (ii) you are not married and filing a separate tax
return,  you can roll over  amounts  from a  Traditional  IRA to a Roth IRA. The
amount rolled over generally will be included in your taxable  income;  however,
if you roll over from a Traditional IRA to a Roth IRA before 1999, you may elect
to have the taxable  amount  included in your  income  ratably  over a four-year
period.  You may also roll over  amounts  from one Roth IRA to another Roth IRA.
Consult your professional tax adviser for complete details on Roth IRAs.

SEP-IRAS -- SEP-IRAs are IRAs that are created in  connection  with a simplified
employee   pension  ("SEP")   established  and  maintained  by  a  self-employed
individual,  a partnership or a  corporation.  SEP-IRAs must be created for each
qualifying  employee of the  employer  that  establishes  a SEP.  In general,  a
qualifying  employee is an employee who has: (i) reached the age of 21; and (ii)
worked for the employer at least three out of the past five years.  Each SEP-IRA
is owned by the employee for whom it is created;  assets of a SEP are not pooled
together.

    SEPs must provide for discretionary employer contributions.  In other words,
employers are not required to make  contributions  to SEP-IRAs each year, but if
they do make  contributions for any year, the  contributions  must be based on a
specific  allocation  formula set forth in the SEP, and must not discriminate in
favor of highly compensated employees.

    Contributions to SEP-IRAs generally are deductible by the employer,  subject
to certain limitations.  Contributions to SEP-IRAs of self-employed  individuals
are subject to certain additional limitations.

    SEP-IRAs  generally are subject to the same  distribution and rollover rules
that apply to Traditional IRAs.

SIMPLE IRAS -- In general,  a SIMPLE plan may be  established  by any  employer,
including a sole proprietorship,  partnership or corporation,  with 100 or fewer
employees, and must be the only retirement plan maintained by the employer.

    Under a SIMPLE  plan using  SIMPLE  IRAs,  a SIMPLE IRA is created  for each
eligible  employee  which,  in general,  includes all  employees who received at
least $5,000 in  compensation  during any two years preceding the year for which
eligibility  is being  determined  (i.e.,  the current  year) and is  reasonably
expected to earn at least  $5,000  during the current  year.  As with  SEP-IRAs,
SIMPLE IRAs are individual accounts owned by each eligible employee.

    Under a SIMPLE  IRA  plan,  eligible  employees  can elect to  contribute  a
portion of their salary to their SIMPLE IRA. (These  contributions  are referred
to as "elective deferrals.") Elective deferrals are based on a stated percentage
of the employee's compensation,  and are limited to $6,000 per year (indexed for
inflation).  Elective deferrals are included in employees' gross income only for
Social Security and Medicare tax purposes (i.e.,  they are not included in wages
for federal income tax purposes).

    In addition to elective  deferrals  by  employees,  under a SIMPLE IRA plan,
employers must make either: (i) matching  contributions equal to each employee's
elective deferral, up to a maximum of 3% of the employee's compensation, or (ii)
nonelective  contributions  of 2% of  compensation  for each  eligible  employee
(subject to certain limits).  Employer contributions to SIMPLE IRAs are excluded
from employees' gross income and are deductible by the employer.

    SIMPLE IRAs  generally  are subject to the same  distribution  and  rollover
rules that apply to Traditional IRAs. However, a rollover from a SIMPLE IRA to a
Traditional IRA can be made tax free only after the employee has participated in
the SIMPLE IRA plan for at least two years.

KEOGH PLANS -- Keogh plans are qualified  retirement  plans  established by sole
proprietors  or  partnerships.  As with other  qualified  retirement  plans,  in
general,   contributions  to  Keogh  plans  are  deductible,  and  neither  such
contributions nor the investment  earnings thereon are subject to tax until they
are distributed by the plan.

    A number of different  types of plans may qualify as Keogh plans. In certain
circumstances,  Keogh plans may provide  greater tax advantages than other types
of  retirement  plans.  However,  Keogh  plans must  satisfy a number of complex
rules,  including  minimum  participation  requirements,   under  which  certain
employees  must be  covered  by the plan,  and in some  cases,  minimum  funding
requirements.  Professional  assistance  generally is required to establish  and
maintain a Keogh plan.

EDUCATION IRAS -- An education IRA is a trust or custodial  account  created for
the purpose of paying the qualified  higher  education  expenses of a designated
beneficiary, i.e., a child under the age of 18 at the time of the contributions.
In general,  qualified higher  education  expenses include expenses for tuition,
fees, books,  supplies and equipment required for the designated  beneficiary of
the Education IRA to attend an eligible educational institution,  which includes
essentially  all  accredited  post  secondary  educational   institutions.   Any
individual  may make  contributions  to an  education  IRA so long as his or her
modified  adjusted  gross  income is less than  $110,000  ($160,000  for married
taxpayers filing jointly).  The maximum total  contributions that may be made to
education IRAs for each child is $500 per year. Generally, amounts may be rolled
over from an education  IRA to another  education IRA  established  for the same
beneficiary or for certain members of the  beneficiary's  family.  Beneficiaries
may  make tax free  withdrawals  from  education  IRAs to pay  qualified  higher
education expenses.  Other withdrawals generally will be subject to tax. Consult
your professional tax adviser for complete details on Education IRAs.

INVESTMENT OBJECTIVE, POLICIES AND RESTRICTIONS

   Security  Capital  Preservation  Fund (the  "Fund") is a  separate  series of
Security Income Fund, an open-end,  management  investment company (mutual fund)
of the series type, offering shares of the Fund ("Shares") as described herein.

   As  described  in the  Fund's  Prospectus,  the  Fund  seeks to  achieve  its
investment  objective by investing all its net investable  assets (the "Assets")
in  BT  PreservationPlus  Income  Portfolio  (the  "Portfolio"),  a  diversified
open-end management  investment company having the same investment  objective as
the Fund. The Portfolio is a separate  subtrust of BT Investment  Portfolios,  a
New York master trust fund (the "Portfolio Trust").

   Because the investment  characteristics  of the Fund  correspond  directly to
those of the  Portfolio  (in  which the Fund  invests  all of its  assets),  the
following is a discussion of the various  investments of and techniques employed
by the  Portfolio.  The  Fund has been  established  to serve as an  alternative
investment to short-term bond funds and money market funds.  In addition,  since
to  date,  there  has  been  no  comparable   investment  substitute  for  those
individuals  who are  "rolling"  assets over from the stable value or guaranteed
investment  contract  ("GIC")  option of their  employee  benefit plans (such as
401(k) plans), the Fund is designed to be that comparable alternative.

   Shares  of the Fund are  sold by  Security  Distributors,  Inc.,  the  Fund's
distributor  (the  "Distributor"),  solely to  tax-sheltered  annuity  custodial
accounts as defined in Section  403(b)(7) of the Internal  Revenue Code of 1986,
as amended (the "Code"),  individual  retirement  accounts as defined in Section
408 of the Code including  "SIMPLE IRAs" and "SEP IRAs", Roth IRAs as defined in
Section 408A of the Code, education individual retirement accounts as defined in
Section 530 of the Code and "Keogh Plans"  (sometimes  collectively  referred to
herein as  "IRAs"),  and to  employees  investing  through  participant-directed
employee benefit plans (each a "Plan" and together "Plans").  Shares are offered
to Plans either  directly,  or through vehicles such as bank collective funds or
insurance company separate accounts  consisting solely of such Plans. Shares are
also  available  to employee  benefit  plans which invest in the Fund through an
omnibus account or similar arrangement.

   The Fund's Prospectus (the "Prospectus") is dated May 1, 1999. The Prospectus
provides the basic information investors should know before investing and may be
obtained without charge by calling the Distributor at  1-800-888-2461  extension
3127.  This  Statement  of  Additional  Information  ("SAI"),  which  is  not  a
prospectus,   is  intended  to  provide  additional  information  regarding  the
activities  and  operations  of the Fund and the Portfolio and should be read in
conjunction  with  the  Prospectus.  This  SAI is not an offer by the Fund to an
investor  that has not received a  Prospectus.  Capitalized  terms not otherwise
defined in this SAI have the meanings ascribed to them in the Prospectus.

INVESTMENT  OBJECTIVE -- The investment objective of the Fund is a high level of
current income while seeking to maintain a stable value per share. There can, of
course, be no assurance that the Fund will achieve its investment objective.

INVESTMENT  POLICIES -- The Fund seeks to achieve its  investment  objective  by
investing  all of its  Assets in the  Portfolio.  The Fund's  investment  in the
Portfolio  may be  withdrawn  at any time if the Board of  Directors of Security
Income Fund determines that it is in the best interests of the Fund to do so.

   The following is a discussion of the various  investments  of and  techniques
employed by the Portfolio.

   SHORT-TERM  INSTRUMENTS.   The  Portfolio  may  hold  short-term  investments
consisting  of foreign and  domestic  (i)  short-term  obligations  of sovereign
governments,  their  agencies,   instrumentalities,   authorities  or  political
subdivisions;  (ii) other short-term debt securities rated in one of the top two
short-term rating categories by an NRSRO or, if unrated,  of comparable  quality
in the opinion of Bankers Trust Company, the Portfolio's investment adviser (the
"Adviser"); (iii) commercial paper; (iv) bank obligations,  including negotiable
certificates  of  deposit,  time  deposits  and  bankers'  acceptances;  and (v)
repurchase  agreements.  At the time the Portfolio  invests in commercial paper,
bank  obligations or repurchase  agreements,  the issuer or the issuer's  parent
must have an  outstanding  long-term  debt  rating of A or higher by  Standard &
Poor's Ratings Group ("S&P") or A-2 or higher by Moody's Investors Service, Inc.
("Moody's") or outstanding commercial paper or bank obligations rated A-1 by S&P
or Prime-1 by Moody's; or, if no such ratings are available, the instrument must
be of comparable quality in the opinion of Bankers Trust.

   CERTIFICATES OF DEPOSIT AND BANKERS' ACCEPTANCES. Certificates of deposit are
receipts  issued by a  depository  institution  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. The certificate usually
can be traded in the secondary  market prior to maturity.  Bankers'  acceptances
typically  arise  from  short-term  credit   arrangements   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.  The acceptance may then be
held  by the  accepting  bank  as an  earning  asset  or it may be  sold  in the
secondary market at the going rate of discount for a specific maturity. Although
maturities for  acceptances can be as long as 270 days,  most  acceptances  have
maturities of six months or less.

   COMMERCIAL PAPER.  Commercial paper consists of short-term  (usually from one
to 270 days)  unsecured  promissory  notes  issued by  corporations  in order to
finance their current operations. A variable amount master demand note (which is
a type of commercial paper) represents a direct borrowing  arrangement involving
periodically  fluctuating  rates of interest under a letter agreement  between a
commercial paper issuer and an institutional lender pursuant to which the lender
may determine to invest varying amounts.

   For a description of commercial paper ratings, see the Appendix.

   MORTGAGE-  AND  ASSET-BACKED  SECURITIES.  The yield  characteristics  of the
mortgage- and  asset-backed  securities in which the Portfolio may invest differ
from those of traditional debt securities.  Among the major differences are that
interest and  principal  payments  are made more  frequently  on  mortgage-  and
asset-backed  securities  (usually monthly) and that principal may be prepaid at
any time because the underlying  mortgage loans or other assets generally may be
prepaid at any time. As a result, if the Portfolio purchases these securities at
a premium,  a  prepayment  rate that is faster than  expected  will reduce their
yield,  while a  prepayment  rate that is  slower  than  expected  will have the
opposite  effect of increasing  yield.  Conversely,  if the Portfolio  purchases
these securities at a discount,  faster than expected prepayments will increase,
while  slower than  expected  prepayments  will  reduce,  their  yield.  Amounts
available for  reinvestment  by the Portfolio are likely to be greater  during a
period of declining interest rates and, as a result, are likely to be reinvested
at lower interest rates than during a period of rising interest rates.

   In general,  the prepayment rate for mortgage-backed  securities decreases as
interest  rates rise and  increases  as  interest  rates fall.  However,  rising
interest rates will tend to decrease the value of these securities. In addition,
an increase in interest rates may affect the  volatility of these  securities by
effectively changing a security that was considered a short-term security at the
time of  purchase  into a long-term  security.  Long-term  securities  generally
fluctuate  more widely in  response to changes in interest  rates than short- or
intermediate-term securities.

   The market for  privately  issued  mortgage- and  asset-backed  securities is
smaller  and less  liquid  than the market for U.S.  government  mortgage-backed
securities.  Collateralized mortgage obligation ("CMO") classes may be specially
structured  in a  manner  that  provides  any of a wide  variety  of  investment
characteristics,   such  as  yield,   effective   maturity  and  interest   rate
sensitivity.  As market  conditions  change,  however,  and particularly  during
periods  of rapid  or  unanticipated  changes  in  market  interest  rates,  the
attractiveness  of the CMO classes and the ability of the  structure  to provide
the anticipated  investment  characteristics may be significantly reduced. These
changes can result in  volatility  in the market  value,  and in some  instances
reduced liquidity, of the CMO class.

   ZERO-COUPON  SECURITIES.  The  Portfolio  may invest in certain  zero  coupon
securities  that are  "stripped"  U.S.  Treasury  notes and bonds.  Zero  coupon
securities usually trade at a substantial discount from their face or par value.
Zero coupon  securities are 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.

   WRAPPER  AGREEMENTS.  Wrapper  Agreements  are  structured  with a number  of
different features.  Wrapper Agreements  purchased by the Portfolio are of three
basic types:  (1)  non-participating,  (2)  participating  and (3)  "hybrid." In
addition,  the Wrapper  Agreements will either be of  fixed-maturity or open-end
maturity  ("evergreen").  The Portfolio  enters into particular types of Wrapper
Agreements depending upon their respective cost to the Portfolio and the Wrapper
Provider's  creditworthiness,   as  well  as  upon  other  factors.  Under  most
circumstances,   it  is   anticipated   that  the  Portfolio   will  enter  into
participating  Wrapper  Agreements  of  open-end  maturity  and  hybrid  Wrapper
Agreements.

   Under a  NON-PARTICIPATING  WRAPPER  AGREEMENT,  the Wrapper Provider becomes
obligated  to make a payment  to the  Portfolio  whenever  the  Portfolio  sells
Covered Assets at a price below Book Value to meet withdrawals of a type covered
by the Wrapper Agreement (a "Benefit Event").  Conversely, the Portfolio becomes
obligated to make a payment to the Wrapper Provider whenever the Portfolio sells
Covered Assets at a price above their Book Value in response to a Benefit Event.
In neither case is the Crediting Rate adjusted at the time of the Benefit Event.
Accordingly,  under  this type of  Wrapper  Agreement,  while the  Portfolio  is
protected against decreases in the market value of the Covered Assets below Book
Value,  it does not realize  increases in the market value of the Covered Assets
above Book Value; those increases are realized by the Wrapper Providers.

   Under a  PARTICIPATING  WRAPPER  AGREEMENT,  the  obligation  of the  Wrapper
Provider or the  Portfolio  to make  payments to each other  typically  does not
arise until all of the Covered Assets have been liquidated.  Instead of payments
being made on the  occurrence of each Benefit  Event,  these  obligations  are a
factor in the periodic adjustment of the Crediting Rate.

   Under a HYBRID WRAPPER  AGREEMENT,  the obligation of the Wrapper Provider or
the  Portfolio  to make  payments  does not  arise  until  withdrawals  exceed a
specified  percentage of the Covered Assets,  after which time payment  covering
the difference between market value and Book Value will occur.

   A FIXED-MATURITY  WRAPPER AGREEMENT  terminates at a specified date, at which
time  settlement  of any  difference  between Book Value and market value of the
Covered Assets occurs. A fixed-maturity  Wrapper  Agreement tends to ensure that
the Covered  Assets  provide a relatively  fixed rate of return over a specified
period of time  through  bond  immunization,  which  targets the duration of the
Covered Assets to the remaining life of the Wrapper Agreement.

   An EVERGREEN  WRAPPER  AGREEMENT has no fixed  maturity date on which payment
must be made, and the rate of return on the Covered Assets  accordingly tends to
vary. Unlike the rate of return under a fixed-maturity  Wrapper  Agreement,  the
rate of return on assets covered by an evergreen Wrapper Agreement tends to more
closely  track  prevailing  market  interest  rates and thus  tends to rise when
interest  rates rise and fall when  interest  rates fall.  An evergreen  Wrapper
Agreement may be converted  into a  fixed-maturity  Wrapper  Agreement that will
mature in the number of years equal to the duration of the Covered Assets.

   Wrapper  Providers  are  banks,   insurance  companies  and  other  financial
institutions.  The number of Wrapper  Providers  has been  increasing  in recent
years. As of April 1998,  there were  approximately  fifteen  Wrapper  Providers
rated in one of the top two  long-term  rating  categories  by  Moody's,  S&P or
another NRSRO.  The cost of Wrapper  Agreements is typically  0.10% to 0.25% per
dollar of Covered Assets per annum.

   In the  event of the  default  of a Wrapper  Provider,  the  Portfolio  could
potentially lose the Book Value protections  provided by the Wrapper  Agreements
with that  Wrapper  Provider.  However,  the  impact  of such a  default  on the
Portfolio as a whole may be minimal or  non-existent  if the market value of the
Covered  Assets  thereunder  is greater than their Book Value at the time of the
default,  because the Wrapper Provider would have no obligation to make payments
to the Portfolio under those  circumstances.  In addition,  the Portfolio may be
able to obtain  another  Wrapper  Agreement  from  another  Wrapper  Provider to
provide Book Value protections with respect to those Covered Assets. The cost of
the  replacement  Wrapper  Agreement  might be higher than the  initial  Wrapper
Agreement due to market conditions or if the market value (plus accrued interest
on the  underlying  securities)  of those Covered Assets is less than their Book
Value at the time of entering into the  replacement  agreement.  Such cost would
also be in addition to any premiums  previously  paid to the defaulting  Wrapper
Provider.  If  the  Portfolio  were  unable  to  obtain  a  replacement  Wrapper
Agreement,  participants  redeeming Shares might experience losses if the market
value of the  Portfolio's  assets no longer covered by the Wrapper  Agreement is
below Book Value.  The  combination of the default of a Wrapper  Provider and an
inability to obtain a replacement  agreement  could render the Portfolio and the
Fund  unable to achieve  their  investment  objective  of seeking to  maintain a
stable value per Share.

   With  respect to  payments  made under the  Wrapper  Agreements  between  the
Portfolio and the Wrapper  Provider,  some Wrapper  Agreements,  as noted in the
Fund's  prospectus,  provide that  payments may be due upon  disposition  of the
Covered Assets, while others provide for payment only upon the total liquidation
of the Covered Assets or upon termination of the Wrapper  Agreement.  In none of
these cases,  however,  would the terms of the Wrapper  Agreements specify which
Portfolio Securities are to be disposed of or liquidated.  Moreover,  because it
is anticipated that each Wrapper Agreement will cover all Covered Assets up to a
specified dollar amount,  if more than one Wrapper Provider becomes obligated to
pay to the  Portfolio the  difference  between Book Value and market value (plus
accrued interest on the underlying securities), each Wrapper Provider will pay a
pro-rata amount in proportion to the maximum dollar amount of coverage provided.
Thus, the Portfolio will not have the option of choosing which Wrapper Agreement
to draw upon in any such  payment  situation.  Under  the terms of most  Wrapper
Agreements,  the Wrapper  Provider  will have the right to terminate the Wrapper
Agreement  in the  event  that  material  changes  are  made to the  Portfolio's
investment  objectives  or  limitations  or to the  nature  of  the  Portfolio's
operations.  In such event,  the  Portfolio  may be obligated to pay the Wrapper
Provider  termination  fees equal in amount to the premiums that would have been
due had the Wrapper Agreement  continued through the predetermined  period.  The
Portfolio  will have the right to terminate a Wrapper  Agreement for any reason.
Such right,  however, may also be subject to the payment of termination fees. In
the event of  termination  of a Wrapper  Agreement or conversion of an evergreen
Wrapper Agreement to a fixed maturity,  some Wrapper Agreements may require that
the  duration  of some  portion  of the  Portfolio's  securities  be  reduced to
correspond to the fixed  maturity or termination  date and that such  securities
maintain a higher  credit  rating  than is  normally  required,  either of which
requirements might adversely affect the return of the Portfolio and the Fund.

   For a description of Wrapper Provider ratings, see the Appendix.

   ILLIQUID SECURITIES.  Mutual funds do not typically hold a significant amount
of  illiquid  securities  because  of the  potential  for  delays on resale  and
uncertainty  in valuation.  Limitations  on resale may have an adverse effect on
the marketability of portfolio securities,  and a mutual fund might be unable to
dispose  of  illiquid  securities  promptly  or at  reasonable  prices and might
thereby experience difficulty satisfying redemptions within seven days. A mutual
fund might also have to register  restricted  securities  in order to dispose of
them, resulting in additional expense and delay. Adverse market conditions could
impede such a public offering of securities.

   In recent  years,  however,  a large  institutional  market has developed for
certain  securities  that  are not  registered  under  the 1933  Act,  including
repurchase   agreements,   commercial  paper,   foreign  securities,   municipal
securities and corporate bonds and notes.  Institutional  investors depend on an
efficient institutional market in which the unregistered security can be readily
resold or on an issuer's ability to honor a demand for repayment.  The fact that
there are contractual or legal restrictions on resale of such investments to the
general  public  or to  certain  institutions  may not be  indicative  of  their
liquidity.

   The  Securities  and  Exchange  Commission  (the "SEC") has adopted Rule 144A
under the 1933 Act,  which  allows a broader  institutional  trading  market for
securities  otherwise  subject to  restriction  on their  resale to the  general
public. Rule 144A establishes a "safe harbor" from the registration requirements
of the 1933 Act for resales of certain  securities  to  qualified  institutional
buyers.  The  Adviser   anticipates  that  the  market  for  certain  restricted
securities  such as  institutional  commercial  paper will  expand  further as a
result of this rule and the  development  of automated  systems for the trading,
clearance  and  settlement  of  unregistered  securities of domestic and foreign
issuers,  such as the PORTAL  System  sponsored by the National  Association  of
Securities Dealers, Inc.

   The Adviser will monitor the  liquidity of Rule 144A  securities  held by the
Portfolio  under the  supervision  of the  Portfolio  Trust  Board.  In reaching
liquidity  decisions,  the  Adviser  will  consider,  among  other  things,  the
following factors: (1) the frequency of trades and quotes for the security;  (2)
the number of dealers and other potential purchasers or sellers of the security;
(3) dealer undertakings to make a market in the security;  and (4) the nature of
the security and of the marketplace  trades (e.g., the time needed to dispose of
the  security,  the  method  of  soliciting  offers  and  the  mechanics  of the
transfer).

   WHEN-ISSUED  AND DELAYED  DELIVERY  SECURITIES.  The  Portfolio  may purchase
securities on a when-issued or delayed  delivery basis.  Delivery of and payment
for  these  securities  can  take  place a month or more  after  the date of the
purchase  commitment.  The purchase price and the interest rate payable, if any,
on the securities are fixed on the purchase  commitment  date or at the time the
settlement  date is fixed.  The value of such  securities  is  subject to market
fluctuation,  and no interest  accrues to the Portfolio until  settlement  takes
place. At the time the Portfolio makes the commitment to purchase  securities on
a when-issued or delayed delivery basis, it will record the transaction, reflect
the value each day of such securities in determining its NAV and, if applicable,
calculate  the maturity for the purposes of average  maturity from that date. At
the time of  settlement,  a when-issued  security may be valued at less than the
purchase  price. To facilitate  such  acquisitions,  the Portfolio will maintain
with its  custodian  (Bankers  Trust) a segregated  account with liquid  assets,
consisting of cash, U.S. government securities or other appropriate  securities,
in an amount at least  equal to such  commitments.  On  delivery  dates for such
transactions,  the Portfolio will meet its obligations  from maturities or sales
of the securities  held in the segregated  account and/or from cash flow. If the
Portfolio  chooses to dispose  of the right to  acquire a  when-issued  security
prior to its  acquisition,  it  could,  as with  the  disposition  of any  other
portfolio  obligation,  realize a gain or loss due to market fluctuation.  It is
the current  policy of the Portfolio not to enter into  when-issued  commitments
exceeding in the  aggregate  15% of the market value of its total  assets,  less
liabilities other than the obligations created by when-issued commitments.

   ADDITIONAL  U.S.  GOVERNMENT   OBLIGATIONS.   The  Portfolio  may  invest  in
obligations   issued   or   guaranteed   by   U.S.    government   agencies   or
instrumentalities. These obligations may or may not be backed by the "full faith
and credit" of the United  States.  In the case of securities  not backed by the
full faith and credit of the United States,  the Portfolio must look principally
to the federal  agency  issuing or  guaranteeing  the  obligation  for  ultimate
repayment and may not be able to assert a claim against the United States itself
in the  event  the  agency  or  instrumentality  does not meet its  commitments.
Securities  in which the  Portfolio  may invest  that are not backed by the full
faith and credit of the  United  States  include  obligations  of the  Tennessee
Valley Authority, the Federal Home Loan Mortgage Corporation and the U.S. Postal
Service,  each of which has the right to borrow  from the U.S.  Treasury to meet
its  obligations,  and  obligations  of the Federal  Farm Credit  System and the
Federal Home Loan Banks,  both of whose obligations may be satisfied only by the
individual credit of the issuing agency.  Securities that are backed by the full
faith and credit of the United  States  include  obligations  of the  Government
National Mortgage  Association (the "GNMA"), the Farmers Home Administration and
the Export-Import Bank.

   LOWER-RATED DEBT SECURITIES ("JUNK BONDS").  The Portfolio may invest in debt
securities  rated in the fifth and sixth  long-term  rating  categories  by S&P,
Moody's and Duff & Phelps Credit Rating Company,  or comparably rated by another
NRSRO,  or if not rated by a NRSRO,  of  comparable  quality  as  determined  by
Bankers Trust in its sole discretion.  While the market for high yield corporate
debt securities has been in existence for many years and has weathered  previous
economic  downturns,  the 1980's brought a dramatic  increase in the use of such
securities to fund highly leveraged  corporate  acquisitions and  restructuring.
Past experience may not provide an accurate  indication of future performance of
the high yield bond market,  especially during periods of economic recession. In
fact,  from 1989 to 1991,  the percentage of lower-rated  debt  securities  that
defaulted rose significantly above prior levels.

   The market for  lower-rated  debt  securities  may be thinner and less active
than that for  higher  rated debt  securities,  which can  adversely  affect the
prices at which the former are sold.  If market  quotations  are not  available,
lower-rated  debt  securities  will be  valued  in  accordance  with  procedures
established  by the Board of  Trustees,  including  the use of  outside  pricing
services.  Judgment  plays a greater role in valuing high yield  corporate  debt
securities  than is the case for securities for which more external  sources for
quotations  and last  sale  information  is  available.  Adverse  publicity  and
changing  investor  perception may affect the  availability  of outside  pricing
services to value  lower-rated  debt securities and the  Portfolio's  ability to
dispose of these securities.

   Since the risk of default is higher for lower-rated debt securities,  Bankers
Trust's  research  and  credit  analysis  are an  especially  important  part of
managing  securities  of  this  type  held  by  the  Portfolio.  In  considering
investments  for the  Portfolio,  Bankers  Trust will attempt to identify  those
issuers of high yielding debt securities whose financial conditions are adequate
to meet future  obligations,  have  improved  or are  expected to improve in the
future.  Bankers  Trust's  analysis  focuses on  relative  values  based on such
factors as interest on dividend coverage, asset coverage, earnings prospects and
the experience and managerial strength of the issuer.

   The Portfolio may choose,  at its expense or in conjunction  with others,  to
pursue litigation or otherwise  exercise its rights as a security holder to seek
to protect the interest of security  holders if it determines  this to be in the
interest of the Portfolio.

   FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS -- GENERAL. The successful
use of these  instruments  draws upon the Adviser's  skill and  experience  with
respect to such  instruments  and  usually  depends on its  ability to  forecast
interest  rate  movements  correctly.  If interest  rates move in an  unexpected
manner,  the  Portfolio  may not  achieve  the  anticipated  benefits of futures
contracts or options  thereon or may realize  losses and thus will be in a worse
position than if such strategies had not been used. In addition, the correlation
between  movements  in the price of futures  contracts  or options  thereon  and
movements  in the price of the  securities  hedged or used for cover will not be
perfect and could produce unanticipated losses.

   FUTURES CONTRACTS. The Portfolio may enter into contracts for the purchase or
sale for future  delivery  of  fixed-income  securities  or  contracts  based on
financial indices,  including any index of U.S. government  securities,  foreign
government securities or corporate debt securities.  U.S. futures contracts have
been designed by exchanges that have been designated  "contracts markets" by the
Commodity  Futures Trading  Commission  ("CFTC") and must be executed  through a
futures commission merchant, or brokerage firm, that is a member of the relevant
contract market.  Futures contracts trade on a number of exchange markets,  and,
through their clearing corporations,  the exchanges guarantee performance of the
contracts as between the clearing  members of the  exchange.  The  Portfolio may
enter into futures  contracts  based on debt  securities  that are backed by the
full faith and credit of the U.S.  government,  such as long-term U.S.  Treasury
bonds,  U.S.  Treasury  notes,   GNMA  modified   pass-through   mortgage-backed
securities and three-month  U.S.  Treasury  bills.  The Portfolio may also enter
into futures contracts that are based on bonds issued by entities other than the
U.S. government.

   At the same time a futures  contract is purchased or sold, the Portfolio must
allocate cash or  securities  as a deposit  payment  ("initial  margin").  It is
expected  that  the  initial  margin  would be  approximately  1 1/2% to 5% of a
contract's  face value.  Daily  thereafter,  the futures  contract is valued and
"variation  margin" may be required  (that is, the Portfolio may have to provide
or may receive  cash that  reflects  any  decline or increase in the  contract's
value).

   At the  time of  delivery  of  securities  pursuant  to a  futures  contract,
adjustments are made to recognize differences in value arising from the delivery
of  securities  with a  different  interest  rate  from  that  specified  in the
contract.  In some  (but not many)  cases,  securities  called  for by a futures
contract may not have been issued when the contract was written.

   Although  futures  contracts  by their terms call for the actual  delivery or
acquisition of securities, in most cases the contractual obligation is fulfilled
before  the  termination  date of the  contract  without  having to make or take
delivery of the  securities.  The  offsetting  of a  contractual  obligation  is
accomplished  by  buying  (or  selling,  as the  case  may be) on a  commodities
exchange an identical  futures  contract calling for delivery in the same month.
Such a transaction,  which is effected through a member of an exchange,  cancels
the  obligation  to  make  or  take  delivery  of  the  securities.   Since  all
transactions  in the  futures  market are made,  offset or  fulfilled  through a
clearinghouse  associated  with the exchange on which the  contracts are traded,
the  Portfolio  will incur  brokerage  fees when it purchases  or sells  futures
contracts.

   The purpose of the Portfolio's  acquisition or sale of a futures  contract is
to attempt to protect the Portfolio from  fluctuations in interest rates without
actually buying or selling  fixed-income  securities.  For example,  if interest
rates were  expected  to  increase  (which  thus would  cause the prices of debt
securities to decline), the Portfolio might enter into futures contracts for the
sale of debt securities.  Such a sale would have much the same effect as selling
an equivalent value of the debt securities  owned by the Portfolio.  If interest
rates did increase, the value of the debt securities held by the Portfolio would
decline,  but the value of the futures contracts to the Portfolio would increase
at  approximately  the same  rate,  thereby  keeping  the  Portfolio's  NAV from
declining as much as it otherwise  would have.  The Portfolio  could  accomplish
similar  results by selling debt  securities  and  investing in bonds with short
maturities  when  interest  rates are expected to increase.  However,  since the
futures market is more liquid than the cash market, the use of futures contracts
as an investment technique allows the Portfolio to maintain a defensive position
without having to sell its portfolio securities.

   Similarly,  when  it is  expected  that  interest  rates  may  decline  (thus
increasing the value of debt securities),  futures contracts for the acquisition
of debt  securities  may be  purchased to attempt to hedge  against  anticipated
purchases of debt  securities at higher prices.  Since the  fluctuations  in the
value of futures  contracts  should be similar to those of the  underlying  debt
securities,  the Portfolio could take advantage of the  anticipated  rise in the
value of debt  securities  without  actually  buying  them  until the market had
stabilized.  At that time,  the futures  contracts  could be liquidated  and the
Portfolio could then buy debt  securities on the cash market.  To the extent the
Portfolio  enters into futures  contracts  for this  purpose,  the assets in the
segregated  asset account  maintained to cover the Portfolio's  obligations with
respect to such futures contracts will consist of cash, cash equivalents or high
quality  liquid debt  securities  from its  portfolio  in an amount equal to the
difference  between the fluctuating  market value of such futures  contracts and
the  aggregate  value of the initial and variation  margin  payments made by the
Portfolio with respect to such futures contracts.

   The ordinary  spreads between prices in the cash and futures  market,  due to
differences in the nature of those markets,  are subject to distortions.  First,
all  participants  in the futures  market are  subject to initial and  variation
margin   requirements.   Rather  than  meeting   additional   variation   margin
requirements,   investors  may  close  futures  contracts   through   offsetting
transactions  that could  distort the normal  relationship  between the cash and
futures  markets.  Second,  the  liquidity  of the  futures  market  depends  on
participants entering into offsetting  transactions rather than making or taking
delivery. To the extent participants decide to make or take delivery,  liquidity
in the futures market could be reduced, thus producing  distortion.  Third, from
the point of view of speculators, the margin deposit requirements in the futures
market are less  onerous  than margin  requirements  in the  securities  market.
Therefore,  increased  participation  by  speculators  in the futures market may
cause  temporary  price  distortions.  Due to the  possibility of distortion,  a
correct  forecast of general interest rate trends by Bankers Trust may still not
result in a successful transaction.

   In addition,  futures  contracts entail risks.  Although the Adviser believes
that  use of such  contracts  will  benefit  the  Portfolio,  if its  investment
judgment  about the  general  direction  of  interest  rates is  incorrect,  the
Portfolio's  overall performance would be poorer than if it had not entered into
any such  contract.  For  example,  if the  Portfolio  has  hedged  against  the
possibility  of an increase in interest  rates that would  adversely  affect the
price of debt  securities  held in its  portfolio  and interest  rates  decrease
instead,  the  Portfolio  will lose part or all of the benefit of the  increased
value of its debt  securities that it has hedged because it will have offsetting
losses  in its  futures  positions.  In  addition,  in such  situations,  if the
Portfolio has  insufficient  cash, it may have to sell debt  securities from its
portfolio to meet daily variation margin requirements.  Such sales of securities
may be, but will not necessarily be, at increased prices that reflect the rising
market.  The  Portfolio  may have to sell  securities  at a time  when it may be
disadvantageous to do so.

   OPTIONS ON FUTURES  CONTRACTS.  The  Portfolio  may purchase and write (sell)
options on futures contracts for hedging purposes. The purchase of a call option
on a futures  contract  is similar in some  respects  to the  purchase of a call
option  on an  individual  security.  Depending  on the  pricing  of the  option
compared to either the price of the futures  contract  upon which it is based or
the price of the  underlying  debt  securities,  it may or may not be less risky
than ownership of the futures  contract or underlying debt  securities.  As with
the purchase of futures  contracts,  when the Portfolio is not fully invested it
may  purchase  a call  option on a futures  contract  to hedge  against a market
advance due to declining interest rates.

   The  writing of a call  option on a futures  contract  constitutes  a partial
hedge against declining prices of the security that is deliverable upon exercise
of the futures  contract.  If the futures  price at  expiration of the option is
below the price specified in the option ("exercise  price"),  the Portfolio will
retain the full amount of the net premium (the premium  received for writing the
option less any  commission),  which will  provide a partial  hedge  against any
decline that may have occurred in its portfolio  holdings.  The writing of a put
option on a futures  contract  constitutes a partial  hedge  against  increasing
prices  of the  security  that  is  deliverable  upon  exercise  of the  futures
contract.  If the futures  price at  expiration of the option is higher than the
exercise  price,  the  Portfolio  will  retain the full amount of the option net
premium, which will provide a partial hedge against any increase in the price of
securities that the Portfolio  intends to purchase.  If a put or call option the
Portfolio has written is exercised,  the Portfolio may incur a loss that will be
reduced by the amount of the net premium it receives. Depending on the degree of
correlation between changes in the value of its portfolio securities and changes
in the value of its futures  positions,  such losses  from  existing  options on
futures  may to some extent be reduced or  increased  by changes in the value of
portfolio securities.

   The  purchase  of a put  option  on a futures  contract  is  similar  in some
respects to the  purchase of put options on portfolio  securities.  For example,
the  Portfolio  may  purchase  a put option on a futures  contract  to hedge its
portfolio  against  the risk of rising  interest  rates.  The amount of risk the
Portfolio  assumes  when it  purchases  an option on a futures  contract  is the
premium paid for the option plus related  transaction  costs. In addition to the
correlation  risks discussed  above,  the purchase of an option also entails the
risk that changes in the value of the  underlying  futures  contract will not be
fully reflected in the value of the option purchased.

   The Portfolio  Trust Board has adopted a restriction  that the Portfolio will
not  enter  into any  futures  contract  or  option  on a  futures  contract  if
immediately  thereafter  the  amount  of  margin  deposits  on all  the  futures
contracts held by the Portfolio and premiums paid on outstanding  options on its
futures contracts (other than those entered into for BONA FIDE hedging purposes)
would exceed 5% of the market value of the Portfolio's total assets.

   OPTIONS ON  SECURITIES.  The Portfolio may write (sell)  covered call and put
options on its portfolio  securities  ("covered options") to a limited extent in
an attempt to increase income.  However, the Portfolio may forgo the benefits of
appreciation  on  securities  sold or may pay  more  than  the  market  price on
securities  acquired  pursuant to call and put options it writes.  A call option
written  by a  Portfolio  is  "covered"  if the  Portfolio  owns the  underlying
security  covered by the call or has an absolute and immediate  right to acquire
that security  without  additional  cash  consideration  (or for additional cash
consideration  held in a segregated account by its custodian) upon conversion or
exchange  of other  securities  held in its  portfolio.  A call  option  is also
covered if the  Portfolio  holds a call option on the same  security  and in the
same principal amount as the written call option where the exercise price of the
call  option  so held  (a) is equal to or less  than the  exercise  price of the
written  call option or (b) is greater  than the  exercise  price of the written
call option if the  difference  is  maintained  by the  Portfolio in cash,  U.S.
government  securities and other high quality liquid  securities in a segregated
account with its custodian.

   When the  Portfolio  writes a covered call option,  it gives the purchaser of
the option the right to buy the  underlying  security at the  exercise  price by
exercising  the  option at any time  during  the  option  period.  If the option
expires unexercised, the Portfolio will realize income in an amount equal to the
premium received for writing the option. If the option is exercised,  a decision
over which the Portfolio has no control,  the Portfolio must sell the underlying
security to the option holder at the exercise  price.  By writing a covered call
option, the Portfolio forgoes, in exchange for the net premium,  the opportunity
to profit  during the option  period from an increase in the market value of the
underlying security above the exercise price.

   When the Portfolio writes a covered put option, it gives the purchaser of the
option  the  right to sell  the  underlying  security  to the  Portfolio  at the
exercise  price at any time  during the  option  period.  If the option  expires
unexercised,  the Portfolio will realize income in the amount of the net premium
received for writing the option. If the put option is exercised, a decision over
which the Portfolio has no control,  the Portfolio  must purchase the underlying
security from the option holder at the exercise  price. By writing a covered put
option,  the Portfolio,  in exchange for the net premium,  accepts the risk of a
decline in the market value of the underlying security below the exercise price.
The  Portfolio  will only write put  options  involving  securities  for which a
determination  is made at the time the  option  is  written  that the  Portfolio
wishes to acquire the securities at the exercise price.

   The Portfolio  may  terminate  its  obligation as the writer of a call or put
option by purchasing an option with the same exercise price and expiration  date
as the option previously written. This transaction is called a "closing purchase
transaction."  The Portfolio will realize a profit or loss on a closing purchase
transaction  if the amount paid to purchase  the option is less or more,  as the
case may be,  than the amount  received  from the sale  thereof.  To close out a
position as a purchaser of an option,  the  Portfolio  may enter into a "closing
sale  transaction,"  which  involves  liquidating  the  Portfolio's  position by
selling the option  previously  purchased.  Where the Portfolio  cannot effect a
closing purchase transaction, it may be forced to incur brokerage commissions or
dealer  spreads in selling  securities  it  receives or it may be forced to hold
underlying securities until an option is exercised or expires.

   When the  Portfolio  writes an  option,  an amount  equal to the net  premium
received is included in the  liability  section of its  Statement  of Assets and
Liabilities  as a deferred  credit.  The amount of the  deferred  credit will be
subsequently marked to market to reflect the current market value of the option.
The current  market  value of a traded  option is the last sale price or, in the
absence of a sale,  the mean  between the closing  bid and asked  prices.  If an
option expires or if the Portfolio enters into a closing  purchase  transaction,
the Portfolio  will realize a gain (or loss if the cost of the closing  purchase
transaction  exceeds the net premium received when the option was sold), and the
deferred  credit related to such option will be eliminated.  If a call option is
exercised,  the  Portfolio  will  realize  a gain or loss  from  the sale of the
underlying  security  and the  proceeds  of the sale  will be  increased  by the
premium originally  received.  The writing of covered call options may be deemed
to  involve  the  pledge of the  securities  against  which the  option is being
written. Securities against which call options are written will be segregated on
the books of the custodian for the Portfolio.

   The Portfolio may purchase call and put options on any securities in which it
may invest.  The Portfolio would normally purchase a call option in anticipation
of an increase in the market  value of such  securities.  The purchase of a call
option  would  entitle the  Portfolio,  in exchange  for the  premium  paid,  to
purchase a security at a specified price during the option period. The Portfolio
would  ordinarily  have a gain the value of the securities  increased  above the
exercise  price  sufficiently  to cover the premium and would have a loss if the
value of the  securities  remained  at or below the  exercise  price  during the
option period.

   The  Portfolio  would  normally  purchase  put options in  anticipation  of a
decline in the market value of securities in its portfolio  ("protective  puts")
or securities of the type in which it is permitted to invest.  The purchase of a
put option would  entitle the  Portfolio,  in exchange for the premium  paid, to
sell a security,  which may or may not be held in the Portfolio's holdings, at a
specified  price during the option  period.  The purchase of protective  puts is
designed  merely to offset or hedge against a decline in the market value of the
Portfolio's holdings. Put options also may be purchased by the Portfolio for the
purpose  of  benefiting  from a  decline  in the  price of  securities  that the
Portfolio does not own. The Portfolio would  ordinarily  recognize a gain if the
value of the securities decreased below the exercise price sufficiently to cover
the premium and would  recognize a loss if the value of the securities  remained
at or above the exercise  price.  Gains and losses on the purchase of protective
put options  would tend to be offset by  countervailing  changes in the value of
underlying portfolio securities.

   The Portfolio has adopted certain non-fundamental  policies concerning option
transactions that are discussed below. The Portfolio's activities in options may
also be restricted by the  requirements of the Internal Revenue Code of 1986, as
amended (the "Code"), for qualification as a regulated investment company.

   The hours of trading for options on  securities  may not conform to the hours
during which the  underlying  securities  are traded if the option markets close
before the markets for the  underlying  securities,  significant  price and rate
movements can take place in the underlying  securities  markets that will not be
reflected  in the option  markets.  It is  impossible  to predict  the volume of
trading  that may exist in such  options,  and there  can be no  assurance  that
viable exchange markets will develop or continue.

   The  Portfolio  may  engage in  over-the-counter  options  transactions  with
broker-dealers who make markets in these options. At present,  approximately ten
broker-dealers,  including  several  of the  largest  primary  dealers  in  U.S.
government   securities,   make  these   markets.   The  ability  to   terminate
over-the-counter  option  positions is more  limited  than with  exchange-traded
option  positions  because the  predominant  market is the issuing broker rather
than an exchange and may involve the risk that  broker-dealers  participating in
such transactions will not fulfill their  obligations.  To reduce this risk, the
Portfolio  will purchase such options only from  broker-dealers  who are primary
U.S. government securities dealers recognized by the Federal Reserve Bank of New
York and who agree to (and are expected to be capable of) entering  into closing
transactions,  although  there can be no guarantee  that any such option will be
liquidated at a favorable price prior to expiration.  Bankers Trust will monitor
the creditworthiness of dealers with whom the Portfolio enters into such options
transactions under the general supervision of the Portfolio Board.

   GLOBAL ASSET ALLOCATION ENHANCEMENT.  In connection with the GAA Strategy and
in addition to the  securities  described  above,  the  Portfolio  may invest in
indexed  securities,   futures  contracts  on  securities  indices,   securities
representing  securities of foreign issuers (e.g. ADRs, GDRs and EDRs),  options
on stocks, options on futures contracts,  foreign currency exchange transactions
and options on foreign currencies.  These are discussed below, to the extent not
already described above.

   INDEXED SECURITIES.  The indexed securities in which the Portfolio may invest
include debt  securities  whose value at maturity is  determined by reference to
the relative prices of various  currencies or to the price of a stock index. The
value of such securities depends on the price of foreign currencies,  securities
indices  or other  financial  values  or  statistics.  These  securities  may be
positively or negatively indexed;  that is, their value may increase or decrease
if the underlying instrument appreciates.

   FUTURES  CONTRACTS ON  SECURITIES  INDICES.  Futures  contracts on securities
indices  provide for the making and acceptance of a cash  settlement  based upon
changes in the value of an index of securities,  and will be entered into by the
Portfolio to hedge against  anticipated  future change in general  market prices
which  otherwise might either  adversely  affect the value of securities held by
the Portfolio or adversely affect the prices of securities which are intended to
be purchased  at a later date for the  Portfolio,  or as an  efficient  means of
managing  allocations  between  asset  classes.  A futures  contract may also be
entered  into to close out or offset an  existing  futures  position.  The risks
attendant  to futures  contracts on  securities  indices are similar to those of
futures contracts, discussed above.

   SECURITIES  REPRESENTING  SECURITIES  OF  FOREIGN  ISSUERS.  The  Portfolio's
investments in the securities of foreign  issuers may be made directly or in the
form of  American  Depositary  Receipts  ("ADRs"),  Global  Depositary  Receipts
("GDRs"),  European  Depositary  Receipts  ("EDRs") or other similar  securities
representing securities of foreign issuers. These securities may not necessarily
be denominated in the same currency as the securities they represent,  and while
designed for use as alternatives to the purchase of the underlying securities in
their  national  markets  and  currencies,  are subject to the same risks as the
foreign securities to which they relate.

   FOREIGN CURRENCY EXCHANGE  TRANSACTIONS.  The Portfolio from time to time may
enter  into  foreign  currency  exchange  transactions  to  convert  to and from
different foreign  currencies and to convert foreign  currencies to and from the
U.S. dollar,  either on a spot (i.e., cash) basis at the spot rate prevailing in
the foreign currency  exchange market,  or through forward contracts to purchase
or sell  foreign  currencies.  A  forward  foreign  currency  exchange  contract
obligates  the  Portfolio  to purchase  or sell a specific  currency at a future
date,  which  may be any fixed  number  of days  from the date of the  contract.
Forward  foreign  currency  exchange  contracts  establish an exchange rate at a
future date.  These contracts are transferable in the interbank market conducted
directly between  currency  traders  (usually large commercial  banks) and their
customers. A forward foreign currency exchange contract generally has no deposit
requirement  and is traded  at a net  price  without  commission.  Neither  spot
transactions  nor  forward  foreign  currency   exchange   contracts   eliminate
fluctuations in the prices of the Portfolio's  securities or in foreign exchange
rates, or prevent loss if the prices of these securities should decline.

   The  Portfolio may enter into foreign  currency  hedging  transactions  in an
attempt to protect  against changes in foreign  currency  exchange rates between
the trade and settlement dates of specific securities transactions or changes in
foreign currency exchange rates that would adversely affect a portfolio position
or an anticipated  investment position.  Since consideration of the prospect for
currency parities will be incorporated into Bankers Trust's long term investment
decisions,  the Portfolio will not routinely enter into foreign currency hedging
transactions  with  respect to security  transactions;  however,  Bankers  Trust
believes  that it is  important  to have the  flexibility  to enter into foreign
currency hedging  transactions when it determines that the transactions would be
in the Portfolio's best interest.  Although these  transactions tend to minimize
the risk of loss due to a decline  in the value of the hedged  currency,  at the
same time they tend to limit any  potential  gain that might be realized  should
the value of the hedged currency  increase.  The precise matching of the forward
contract amounts and the value of the securities  involved will not generally be
possible because the future value of such securities in foreign  currencies will
change as a  consequence  of market  movements  in the value of such  securities
between the date the forward  contract is entered  into and the date it matures.
The  projection of currency  market  movements is extremely  difficult,  and the
successful execution of a hedging strategy is highly uncertain.

   OPTIONS ON FOREIGN  CURRENCIES.  The Portfolio may write covered put and call
options and purchase put and call options on foreign  currencies for the purpose
of protecting  against declines in the dollar value of portfolio  securities and
against increases in the dollar cost of securities to be acquired. The Portfolio
may use options on currency to cross hedge, which involves writing or purchasing
options  on one  currency  to hedge  against  changes  in  exchange  rates for a
different,  but related currency.  As with other types of options,  however, the
writing of an option on foreign currency will constitute only a partial hedge up
to the amount of the premium  received,  and the Portfolio  could be required to
purchase or sell foreign currencies at disadvantageous  exchange rates,  thereby
incurring  losses.  The purchase of an option on foreign currency may be used to
hedge against fluctuations in exchange rates although,  in the event of exchange
rate movements  adverse to the Portfolio's  position,  it may forfeit the entire
amount of the premium plus related transaction costs. In addition, the Portfolio
may purchase  call  options on currency  when the Adviser  anticipates  that the
currency will appreciate in value.

   There is no assurance that a liquid  secondary  market on an options exchange
will  exist  for  any  particular  option,  or at any  particular  time.  If the
Portfolio  is unable to effect a closing  purchase  transaction  with respect to
covered  options  it has  written,  the  Portfolio  will not be able to sell the
underlying  currency or dispose of assets held in a segregated account until the
options expire or are exercised. Similarly, if the Portfolio is unable to effect
a closing sale  transaction  with respect to options it has purchased,  it would
have to  exercise  the  options  in order to  realize  any profit and will incur
transaction  costs  upon  the  purchase  or sale  of  underlying  currency.  The
Portfolio pays brokerage  commissions or spreads in connection  with its options
transactions.

   As in the case of forward  contracts,  certain options on foreign  currencies
are traded over the counter and involve liquidity and credit risks which may not
be present in the case of exchange  traded  currency  options.  The  Portfolio's
ability to terminate OTC options will be more limited than with exchange  traded
options.  It is also possible that broker dealers  participating  in OTC options
transactions will not fulfill their obligations. Until such time as the staff of
the SEC changes its position, the Portfolio will treat purchased OTC options and
assets used to cover written OTC options as illiquid securities. With respect to
options written with primary dealers in U.S.  Government  securities pursuant to
an agreement  requiring a closing  purchase  transaction at a formula price, the
amount of illiquid securities may be calculated with reference to the repurchase
formula.

   There can be no assurance that the use of these portfolio  strategies will be
successful.

RATING SERVICES -- The ratings of rating services represent their opinions as to
the  quality  of the  securities  that  they  undertake  to rate.  It  should be
emphasized,  however,  that  ratings are  relative  and  subjective  and are not
absolute  standards of quality.  Although these ratings are an initial criterion
for  selection  of  portfolio  investments,  the  Adviser  also  makes  its  own
evaluation of these securities,  subject to review by the Portfolio Trust Board.
After  purchase by the  Portfolio,  an  obligation  may cease to be rated or its
rating may be reduced below the minimum  required for purchase by the Portfolio.
Neither event would require the Portfolio to eliminate the  obligation  from its
portfolio,  but the Adviser will consider such an event in its  determination of
whether the Portfolio  should continue to hold the obligation.  A description of
the  ratings  referred  to  herein  and in the  Prospectus  is set  forth in the
Appendix.

INVESTMENT   RESTRICTIONS   --  The  following   investment   restrictions   are
"fundamental  policies"  of the Fund and the  Portfolio  and may not be  changed
without the approval of a "majority of the outstanding voting securities" of the
Fund or the Portfolio,  as the case may be. "Majority of the outstanding  voting
securities"  under  the 1940  Act,  and as used in this SAI and the  Prospectus,
means,  with  respect to the Fund (or the  Portfolio),  the lesser of (1) 67% or
more  of the  outstanding  voting  securities  of  the  Fund  (or  of the  total
beneficial  interests of the Portfolio) present at a meeting,  if the holders of
more than 50% of the outstanding  voting securities of the Fund (or of the total
beneficial  interests of the  Portfolio)  are present or represented by proxy or
(2) more than 50% of the  outstanding  voting  securities of the Fund (or of the
total beneficial interests of the Portfolio).  Whenever the Fund is requested to
vote on a  fundamental  policy of the  Portfolio,  it will hold a meeting of the
Fund's  shareholders  and  will  cast  its  vote as  instructed  by  them.  Fund
shareholders  who do not vote will not affect the Fund's votes at the  Portfolio
meeting.  The Fund's votes  representing  Fund  shareholders  not voting will be
voted by the  Directors of Security  Income Fund in the same  proportion  as the
Fund shareholders who do, in fact, vote.

   None of the fundamental and  non-fundamental  policies  described below shall
prevent  the Fund from  investing  all of its assets in an  open-end  investment
company with substantially the same investment  objective.  Because the Fund and
the Portfolio have the same fundamental policies and the Fund invests all of its
Assets in the Portfolio,  the following  discussion (though speaking only of the
Portfolio) applies to the Fund as well.

   FUNDAMENTAL  RESTRICTIONS.  As a matter of fundamental  policy, the Portfolio
may not:

1.   Borrow  money  (including   through  reverse   repurchase  or  dollar  roll
     transactions)  in excess of 5% of the  Portfolio's  total assets  (taken at
     cost),  except that the  Portfolio  may borrow for  temporary  or emergency
     purposes up to 1/3 of its total assets. The Portfolio may pledge,  mortgage
     or hypothecate  not more than 1/3 of such assets to secure such  borrowings
     provided that collateral  arrangements with respect to options and futures,
     including  deposits of initial and variation  margin,  are not considered a
     pledge of assets for  purposes of this  restriction  and except that assets
     may be  pledged  to secure  letters  of credit  solely  for the  purpose of
     participating in a captive  insurance  company  sponsored by the Investment
     Company Institute;

2.   Underwrite  securities  issued  by  other  persons  except  insofar  as the
     Portfolio  may be deemed  an  underwriter  under the 1933 Act in  selling a
     portfolio security;

3.   Make  loans  to  other  persons  except  (a)  through  the  lending  of the
     Portfolio's  portfolio  securities  and  provided  that any such  loans not
     exceed 30% of its total assets (taken at market value); (b) through the use
     of repurchase agreements or the purchase of short-term obligations;  or (c)
     by purchasing a portion of an issue of debt securities of types distributed
     publicly or privately;

4.   Purchase or sell real estate (including limited  partnership  interests but
     excluding   securities  secured  by  real  estate  or  interests  therein),
     interests in oil, gas or mineral leases, commodities or commodity contracts
     (except  futures and option  contracts) in the ordinary  course of business
     (except  that the  Portfolio  may hold and sell,  for its  portfolio,  real
     estate acquired as a result of the Portfolio's ownership of securities);

5.   Concentrate  its  investments in any particular  industry  (excluding  U.S.
     government securities), but if it is deemed appropriate for the achievement
     of the Portfolio's investment objective,  up to 25% of its total assets may
     be invested in any one industry;

6.   Issue any senior security (as that term is defined in the 1940 Act) if such
     issuance  is  specifically  prohibited  by the  1940 Act or the  rules  and
     regulations promulgated  thereunder,  provided that collateral arrangements
     with  respect to options  and  futures  contracts,  including  deposits  of
     initial and variation  margin,  are not  considered to be the issuance of a
     senior security for purposes of this restriction;

7.   Purchase,  with respect to 75% of the Portfolio's total assets,  securities
     of any  issuer  if such  purchase  at the  time  thereof  would  cause  the
     Portfolio to hold more than 10% of any class of  securities of such issuer,
     for which purposes all  indebtedness  of an issuer shall be deemed a single
     class and all preferred  stock of an issuer shall be deemed a single class,
     except  that  options  or  futures  contracts  shall not be subject to this
     restriction; and

8.   Invest,  with respect to 75% of the Portfolio's total assets,  more than 5%
     of  its  total  assets  in  the  securities   (excluding  U.S.   government
     securities) of any one issuer.

   NON-FUNDAMENTAL  RESTRICTIONS.  In order to comply with certain  statutes and
policies and for other reasons, the Portfolio will not, as a matter of operating
policy (these restrictions may be changed without shareholder approval):

(i)  purchase  any  security or evidence of interest  therein on margin,  except
     that short-term  credit  necessary for the clearance of purchases and sales
     of securities may be obtained and deposits of initial and variation  margin
     may be made in connection with the purchase,  ownership, holding or sale of
     futures contracts;

(ii) sell securities it does not own (short sales).  (This  restriction does not
     preclude  short sales  "against the box" (that is, sales of securities  (a)
     the  Portfolio  contemporaneously  owns or (b) where the  Portfolio has the
     right to obtain  securities  equivalent  in kind and amount to those sold).
     The Portfolio has no current intention to engage in short selling);

(iii)purchase  securities issued by any investment  company except to the extent
     permitted  by  the  1940  Act   (including  any  exemptions  or  exclusions
     therefrom),  except  that  this  limitation  does not  apply to  securities
     received or acquired as  dividends,  through  offers of  exchange,  or as a
     result of reorganization, consolidation or merger; and

(iv) invest more than 15% of the Portfolio's net assets (taken at the greater of
     cost or market  value)  in  securities  that are  illiquid  or not  readily
     marketable (excluding Rule 144A securities deemed by the Portfolio Board to
     be liquid).

   An investment restriction will not be considered violated if that restriction
is complied  with at the time the relevant  action is taken,  notwithstanding  a
later change in the market value of an investment,  in net or total assets or in
the change of securities rating of the investment or any other later change.

   The  Portfolio  will comply with the  permitted  investments  and  investment
limitations  in the securities  laws and  regulations of all states in which the
Fund, or any other registered investment company investing in the Portfolio,  is
registered.

PORTFOLIO  TRANSACTIONS AND BROKERAGE  COMMISSIONS -- The Adviser is responsible
for decisions to buy and sell securities,  futures contracts and options thereon
for the  Portfolio,  the  selection of brokers,  dealers and futures  commission
merchants to effect  transactions and the negotiation of brokerage  commissions,
if  any.   Broker-dealers   may  receive  brokerage   commissions  on  portfolio
transactions,  including  options,  futures  contracts  and  options  on futures
transactions  and the  purchase  and  sale of  underlying  securities  upon  the
exercise of options.  Orders may be  directed  to any  broker-dealer  or futures
commission  merchant,  including,  to the extent and in the manner  permitted by
applicable  law, the Adviser or its  subsidiaries  or affiliates.  Purchases and
sales of certain portfolio  securities on behalf of the Portfolio are frequently
placed by the Adviser with the issuer or a primary or secondary market-maker for
these securities on a net basis,  without any brokerage commission being paid by
the Portfolio.  Trading does, however,  involve transaction costs.  Transactions
with dealers  serving as  market-makers  reflect the spread  between the bid and
asked prices.  Transaction costs may also include fees paid to third parties for
information as to potential  purchasers or sellers of  securities.  Purchases of
underwritten  issues may be made that will include an  underwriting  fee paid to
the underwriter.

   The Adviser  seeks to evaluate the overall  reasonableness  of the  brokerage
commissions  paid (to the extent  applicable) in placing orders for the purchase
and sale of  securities  for the  Portfolio  taking into account such factors as
price,  commission  (negotiable  in the  case of  national  securities  exchange
transactions), if any, size of order, difficulty of execution and skill required
of the executing  broker-dealer  through familiarity with commissions charged on
comparable  transactions,  as  well  as by  comparing  commissions  paid  by the
Portfolio  to reported  commissions  paid by others.  The  Adviser  reviews on a
routine basis commission  rates,  execution and settlement  services  performed,
making internal and external comparisons. The Adviser is authorized,  consistent
with Section  28(e) of the  Securities  Exchange Act of 1934,  as amended,  when
placing  portfolio  transactions  for  the  Portfolio  with  a  broker  to pay a
brokerage  commission (to the extent applicable) in excess of that which another
broker might have charged for effecting the same  transaction  on account of the
receipt of research,  market or  statistical  information.  The term  "research,
market or  statistical  information"  includes (a) advice as to (i) the value of
securities,  (ii) the  advisability  of  investing  in,  purchasing  or  selling
securities, and (iii) the availability of securities or purchasers or sellers of
securities  and  (b)  furnishing   analyses  and  reports  concerning   issuers,
industries,  securities, economic factors and trends, portfolio strategy and the
performance of accounts.  Higher  commissions  may be paid to firms that provide
research  services  to the extent  permitted  by law.  The  Adviser may use this
research  information in managing the Portfolio's  assets, as well as the assets
of other clients.  Consistent with the policy stated above, the Conduct Rules of
the National Association of Securities Dealers,  Inc. and such other policies as
the  Portfolio  Trust Board may  determine,  the Adviser may  consider  sales of
shares of the Fund and of other  investment  company clients of the Adviser as a
factor in the selection of broker-dealers to execute portfolio transactions. The
Adviser  will make such  allocations  if  commissions  are  comparable  to those
charged by nonaffiliated,  qualified broker-dealers for similar services. Except
for  implementing  the  policies  stated  above,  there is no intention to place
portfolio  transactions with particular brokers or dealers or groups thereof. In
effecting  transactions in over-the-counter  securities,  orders are placed with
the  principal  market-makers  for  the  security  being  traded  unless,  after
exercising care, it appears that more favorable results are available otherwise.
Although certain  research,  market or statistical  information from brokers and
dealers can be useful to the Portfolio and to the Adviser,  it is the opinion of
the Portfolio's  management that such  information is only  supplementary to the
Adviser's own research  effort,  since the  information  must still be analyzed,
weighed and reviewed by the Adviser's  staff.  Such information may be useful to
the Adviser in providing  services to clients other than the Portfolio,  and not
all such  information  is used by the Adviser in connection  with the Portfolio.
Conversely,  such  information  provided  to the  Adviser by brokers and dealers
through whom other clients of the Adviser effect securities  transactions may be
useful to the  Adviser  in  providing  services  to the  Portfolio.  In  certain
instances there may be securities  that are suitable for the Portfolio,  as well
as for one or more of the Adviser's other clients.  Investment decisions for the
Portfolio and for the Adviser's  other clients are made with a view to achieving
their  respective  investment  objectives.  It may  develop  that  a  particular
security  is bought or sold for only one client even though it might be held by,
or bought or sold for, other  clients.  Likewise,  a particular  security may be
bought for one or more  clients  when one or more  clients are selling that same
security.  Some  simultaneous  transactions  are inevitable when several clients
receive  investment advice from the same investment  adviser,  particularly when
the same  security is suitable for the  investment  objectives  of more than one
client.  When two or more clients are simultaneously  engaged in the purchase or
sale of the same security,  the securities are allocated between (among) clients
in a manner  believed to be equitable  to each.  It is  recognized  that in some
cases this system could have a detrimental  effect on the price or volume of the
security as far as the Portfolio is concerned.  However, it is believed that the
ability of the  Portfolio to  participate  in volume  transactions  will produce
better executions for the Portfolio.

PERFORMANCE INFORMATION

STANDARD PERFORMANCE  INFORMATION -- From time to time, quotations of the Fund's
performance may be included in  advertisements,  sales literature or shareholder
reports. These performance figures are calculated in the following manner:

   YIELD.  Yield refers to the income  generated by an  investment  over a given
period of time,  expressed as an annual  percentage rate.  Yields are calculated
according to a standard  that is required  for all stock and bond mutual  funds.
Because  this differs from other  accounting  methods,  the quoted yield may not
equal the income actually paid to shareholders.

   Performance  information  or  advertisements  may include  comparisons of the
Fund's  investment  results  to  various  unmanaged  indices or results of other
mutual funds or investment or savings  vehicles.  From time to time,  the Fund's
ranking may be quoted from various sources,  such as Lipper Analytical Services,
Inc., Value Line, Inc. and Morningstar, Inc.

   Unlike some bank deposits or other  investments  that pay a fixed yield for a
stated period of time,  the total return of the Shares will vary  depending upon
interest rates, the current market value of the securities held by the Portfolio
and the Wrapper  Agreements  and  changes in the  expenses of the Shares and the
Portfolio. In addition,  during certain periods for which yield and total return
may be provided, the Fund's administrator, Security Management Company, LLC, may
have voluntarily  agreed to waive portions of its fees, or to reimburse  certain
operating  expenses of the Fund, on a  month-to-month  basis.  Bankers Trust may
have agreed to do the same with respect to the Portfolio. Such waivers will have
the effect of  increasing  the Fund's net income  (and  therefore  its yield and
total return) during the period such waivers are in effect.

   TOTAL  RETURN.  The Fund's  average  annual  total return is  calculated  for
certain  periods by determining  the average annual  compounded  rates of return
over those periods that would cause an investment of $1,000 (made at the maximum
public offering price with all  distributions  reinvested) to reach the value of
that  investment at the end of the periods.  The Fund may also  calculate  total
return  figures  that  represent   aggregate   performance   over  a  period  or
year-by-year performance.

   PERFORMANCE RESULTS. Any performance information provided for the Fund should
not be considered as  representative  of its performance in the future,  because
the NAV and  public  offering  price of Shares  will vary  based not only on the
type, quality and maturities of the securities held by the Portfolio but also on
changes in the current value of such  securities  and on changes in the expenses
of the Fund and the  Portfolio.  Total return  reflects the  performance of both
principal and income.

   Unless noted  otherwise,  the Fund's  total  return and average  annual total
return will reflect  deduction of the maximum  initial sales load in the case of
Class A shares or the  applicable  deferred  sales charge in the case of Class B
and  Class C  shares.  From  time to  time  the  Fund  may  include  performance
information in  advertisements  and sales  literature  without  deduction of the
sales charge, which, if deducted, would reduce the performance data quoted.

COMPARISON  OF FUND  PERFORMANCE  --  Comparison  of the quoted  nonstandardized
performance of various investments is valid only if performance is calculated in
the same manner.  Since there are different methods of calculating  performance,
investors   should  consider  the  effect  of  the  methods  used  to  calculate
performance when comparing  performance of the Fund with performance quoted with
respect to other investment companies or types of investments.

   In connection  with  communicating  its performance to current or prospective
shareholders,  the Fund also may compare  these  figures to the  performance  of
other  mutual  funds  tracked by mutual  fund rating  services  or to  unmanaged
indices that may assume  reinvestment  of dividends but generally do not reflect
deductions for  administrative  and management costs.  Evaluations of the Fund's
performance  made by  independent  sources  may  also be used in  advertisements
concerning  the Fund.  Sources  for the  Fund's  performance  information  could
include the  following:  ASIAN WALL STREET  JOURNAL,  BARRON'S,  BUSINESS  WEEK,
CHANGING  TIMES,  THE KIPLINGER  MAGAZINE,  CONSUMER  DIGEST,  FINANCIAL  TIMES,
FINANCIAL WORLD,  FORBES,  FORTUNE,  GLOBAL INVESTOR,  INVESTOR'S DAILY,  LIPPER
ANALYTICAL SERVICES, INC.'S MUTUAL FUND PERFORMANCE ANALYSIS, MONEY, MORNINGSTAR
INC., NEW YORK TIMES, PERSONAL INVESTING NEWS, PERSONAL INVESTOR,  SUCCESS, U.S.
NEWS AND WORLD REPORT, VALUELINE,  WALL STREET JOURNAL,  WEISENBERGER INVESTMENT
COMPANIES SERVICES, WORKING WOMEN and WORTH.

ECONOMIC AND MARKET  INFORMATION -- Advertising and sales literature of the Fund
may include  discussions of economic,  financial and political  developments and
their effect on the securities  market.  Such  discussions  may take the form of
commentary on these  developments by Fund portfolio managers and their views and
analysis  on  how  such  developments   could  affect  the  Fund.  In  addition,
advertising  and  sales   literature  may  quote  statistics  and  give  general
information  about  the  mutual  fund  industry,  including  the  growth  of the
industry,  from sources such as the Investment  Company Institute  ("ICI").  For
example,  according to the ICI,  thirty-seven percent of American households are
pursuing their financial goals through mutual funds. These investors, as well as
businesses and institutions,  have entrusted over $3.5 trillion to the more than
6,000 funds available.

VALUATION OF ASSETS; REDEMPTIONS IN KIND

Debt securities  (other than short-term debt obligations  maturing in 60 days or
less), including listed securities and securities for which price quotations are
available,  will normally be valued on the basis of market valuations  furnished
by a pricing service. Such market valuations may represent the last quoted price
on the  securities'  major trading  exchange or quotes  received from dealers or
market makers in the relevant securities or may be determined through the use of
matrix  pricing.  In matrix  pricing,  pricing  services may use various pricing
models,  involving  comparable  securities,  historic  relative price movements,
economic  factors  and  dealer  quotations.   Over-the-counter  securities  will
normally  be valued at the bid  price.  Short-term  debt  obligations  and money
market securities maturing in 60 days or less are valued at amortized cost.

   Securities for which market  quotations are not readily  available are valued
by Bankers Trust pursuant to procedures adopted by the Portfolio's Trust Board.

   The  NAV per  Share  is  calculated  once  on  each  Valuation  Day as of the
Valuation  Time,  which is currently  3:00 p.m.,  Central  time,  or if the NYSE
closes early,  at the time of such early closing.  The NAV per Share is computed
by dividing the value of the Fund's assets (I.E., the value of its investment in
the Portfolio  and other assets,  if any),  less all  liabilities,  by the total
number of its Shares  outstanding.  The Portfolio's  securities and other assets
are valued primarily on the basis of market quotations or, if quotations are not
readily  available,  by  a  method  that  the  Portfolio  Trust  Board  believes
accurately reflects fair value.

   Pursuant to  procedures  adopted by the  Portfolio  Trust Board,  the Wrapper
Value  generally will be equal to the difference  between the Book Value and the
market  value  (plus  accrued  interest  on the  underlying  securities)  of the
applicable  Covered  Assets.  If the market value (plus accrued  interest on the
underlying  securities)  of the Covered Assets is greater than their Book Value,
the Wrapper  Value will be  reflected  as a liability  of the  Portfolio  in the
amount of the  difference,  I.E., a negative  value,  reflecting  the  potential
liability of the  Portfolio to the Wrapper  Provider.  If the market value (plus
accrued  interest on the  underlying  securities)  of the Covered Assets is less
than their Book Value,  the Wrapper  Value will be  reflected as an asset of the
Portfolio in the amount of the difference,  I.E., a positive  value,  reflecting
the potential liability of the Wrapper Provider to the Portfolio.  In performing
its fair value determination,  the Portfolio Trust Board expects to consider the
creditworthiness  and ability of a Wrapper Provider to pay amounts due under the
Wrapper  Agreement.  If the  Portfolio  Trust  Board  determine  that a  Wrapper
Provider is unable to make such payments,  that Board may assign a fair value to
the Wrapper  Agreement that is less than the  difference  between the Book Value
and the market value (plus accrued interest on the underlying securities) of the
applicable  Covered  Assets and the  Portfolio  might be unable to maintain  NAV
stability.

   The  problems  inherent  in making a good  faith  determination  of value are
recognized in the codification effected by SEC Financial Reporting Release No. 1
(formerly  Accounting  Series Release No. 113) ("FRR 1"),  which  concludes that
there  is "no  automatic  formula"  for  calculating  the  value  of  restricted
securities.  It  recommends  that the best  method  simply  is to  consider  all
relevant factors before making any calculation. According to FRR 1, such factors
would include consideration of the --

     type of security involved,  financial statements, cost at date of purchase,
     size of holding,  discount from market value of unrestricted  securities of
     the  same  class at the  time of  purchase,  special  reports  prepared  by
     analysts,  information as to any transactions or offers with respect to the
     security,  existence of merger  proposals or tender  offers  affecting  the
     security,  price and extent of public trading in similar  securities of the
     issuer or comparable companies, and other relevant matters.

   The  Adviser  will  value  securities  purchased  by the  Portfolio  that are
restricted as to resale or for which current  market  quotations are not readily
available,  including  Wrapper  Agreements,  based upon all relevant  factors as
outlined in FRR 1.

   The Fund and the Portfolio each reserves the right, if conditions  exist that
make cash payments  undesirable,  or for other reasons, to honor any request for
redemption or  withdrawal,  respectively,  by making payment wholly or partly in
Portfolio Securities (a "redemption in kind"). Such securities shall not include
Wrapper  Agreements,  and shall be valued as they are for  purposes of computing
the Fund's or the  Portfolio's  NAV, as the case may be. If payment is made to a
Fund shareholder in securities,  the shareholder may incur transaction  expenses
in converting those securities into cash.

   The  Portfolio  has agreed to make a redemption  in kind to the Fund whenever
the Fund  wishes to make a  redemption  in kind to a  shareholder  thereof,  and
therefore  Fund  shareholders  that  receive  redemptions  in kind will  receive
Portfolio  Securities  of the  Portfolio  and in no case  will  they  receive  a
security issued by the Portfolio. The Portfolio has advised Security Income Fund
that the Portfolio will not redeem in kind except in  circumstances in which the
Fund is permitted to redeem in kind or unless requested by the Fund.

   Each investor in the Portfolio,  including the Fund, may add to or reduce its
investment in the Portfolio on each  business day the Portfolio  determines  its
NAV.  At the close of business  on each such day,  the value of each  investor's
beneficial  interest in the Portfolio will be determined by multiplying  the NAV
of the Portfolio by the percentage  effective for that day that  represents that
investor's  share of the aggregate  beneficial  interests in the Portfolio.  Any
additions or withdrawals  that are to be effected as of the close of business on
that day will then be  effected.  The  investor's  percentage  of the  aggregate
beneficial  interests in the Portfolio will then be recomputed as the percentage
equal to a fraction (a) the  numerator  of which is the value of the  investor's
investment  in the  Portfolio  as of the close of  business  on that day plus or
minus,  as the case may be, the amount of net additions to or  withdrawals  from
the investor's  investment in the Portfolio effected as of the close of business
on that  day,  and (b) the  denominator  of  which is the  aggregate  NAV of the
Portfolio as of the close of business on that day plus or minus, as the case may
be, the amount of net additions to or withdrawals from the aggregate investments
in the Portfolio by all investors  therein.  The  percentage so determined  will
then be  applied  to  determine  the  value of the  investor's  interest  in the
Portfolio as the close of business on the following business day.

QUALIFIED REDEMPTIONS

At any time, a redemption of Fund Shares can be effected  without  assessment of
the  Redemption  Fee  described  in  "Shareholder  Transaction  Expenses" in the
Prospectus,  if such  redemption  is a  "Qualified  TSA Account  Redemption,"  a
"Qualified  Plan  Redemption" or a "Qualified IRA  Redemption."  "Qualified Plan
Redemptions"  are  redemptions   resulting  from  a  Plan  Participant's  death,
disability,  retirement or termination of employment or to fund loans to, or "in
service"   withdrawals  by,  a  Plan  Participant.   

   A "Qualified TSA Account  Redemption"  is a redemption  made by an owner of a
TSA Account to effect a distribution from his or her account that is not subject
to the 10% penalty tax imposed by section  72(t),  other than a rollover  from a
TSA  Account  to an IRA or other  TSA  Account  and,  direct  trustee-to-trustee
transfers,  unless the owner continues the investment of the transferred  amount
in the Fund. In general,  section 72(t) of the Code imposes a 10% penalty tax on
any distribution received by a taxpayer who owns a TSA Account prior to the date
on which the  taxpayer  reaches age 59 1/2,  unless the  distribution  meets the
requirements of a specific  exception to the penalty tax. In general,  rollovers
from a TSA  Account  to an IRA,  from one TSA  Account  to  another  and  direct
trustee-to-trustee transfers from one TSA Account to another TSA Account are not
subject to tax. TSA Account  owners  requesting a redemption of Fund Shares will
be required  to provide a written  statement  as to whether the  proceeds of the
redemption  will be  subject  to a penalty  tax and,  if not,  to  identify  the
specific  exception  upon  which  the owner  intends  to rely.  The  information
provided by the owner will be reflected  on the Form 1099-R  issued to the owner
and filed with the Internal Revenue Service in connection with the redemption as
well as forming the basis for redemption as a Qualified TSA Account  Redemption.
The Fund may  require  additional  evidence,  such as the opinion of a certified
public  accountant or tax attorney,  that any particular  redemption will not be
subject to any penalty tax. TSA ACCOUNT OWNERS SHOULD CONSULT THEIR TAX ADVISERS
REGARDING THE TAX CONSEQUENCES OF ANY REDEMPTION.

   Some of the  exceptions to the 10% penalty taxes are  described  below.  This
description  is  intended  to  provide  only a brief  summary  of the  principal
exceptions to the additional tax imposed on early  withdrawals under the current
provisions of the Code,  which may change from time to time. The Fund intends to
conform  the  definition  of  Qualified  TSA Account  Redemptions  to changes in
applicable tax laws; however,  the Fund reserves the right to continue to define
Qualified TSA Account  Redemptions by reference to Code provisions now in effect
or otherwise to define such phrase independently of future Code provisions.

   In  general,  the early  withdrawal  penalty tax imposed by the Code will not
apply to the following types of distributions from a TSA Account:

1.   Distributions  made on or after  the date on which  the TSA  Account  owner
     attains age 59 1/2;

2.   Distributions  made to a  beneficiary  (or to the estate of the TSA Account
     owner) on or after the death of the TSA Account owner;

3.   Distributions attributable to the TSA Account owner being disabled;

4.   Distributions  made to the TSA Account owner after  separation from service
     after age 55;

5.   Distributions  to an alternate  payee (e.g. a former spouse)  pursuant to a
     qualified domestic relations order;

6.   Distributions  that are part of a series of  substantially  equal  periodic
     payments made at least  annually for the life (or life  expectancy)  of the
     TSA Account  owner,  or the joint lives (or life  expectancies)  of the TSA
     Account owner and his or her designated beneficiary,  after the TSA Account
     owner separates from service;

7.   Distributions  made to a TSA  Account  owner for medical  care,  but not in
     excess of the amount  allowable as a medical  expense  deduction by the TSA
     Account owner on his or her tax return for the year;

8.   Distributions timely made to correct an excess contribution; and

9.   Distributions timely made to reduce an excess elective deferral.

   A "Qualified IRA Redemption" is a redemption made by an IRA Owner to effect a
distribution  from his or her IRA account that is not subject to the 10% penalty
tax imposed by section 72(t) or 530(d), as applicable, other than IRA rollovers,
direct trustee-to-trustee  transfers and conversions of Traditional IRAs to Roth
IRAs, unless the IRA Owner continues the investment of the transferred amount in
the Fund. In general, section 72(t) of the Code imposes a 10% penalty tax on any
distribution  received by a taxpayer from a Traditional  IRA,  SEP-IRA or SIMPLE
IRA prior to the date on which  the  taxpayer  reaches  age 59 1/2,  unless  the
distribution  meets the requirements of a specific exception to the penalty tax.
Similar  penalties  apply to early  withdrawals  from Roth IRAs and Keogh Plans.
Section  530(d) as  currently  written,  imposes a separate  10%  penalty tax on
distributions  from an education IRA not used to pay qualified  higher education
expenses.   In   general,   rollovers   from  one  IRA  to  another  and  direct
trustee-to-trustee  transfers  from an IRA to  another  IRA (or in some cases to
other types of qualified plans) are not subject to tax. In addition, conversions
of  Traditional  IRAs to Roth IRAs are subject to income tax but are not subject
to the early withdrawal  penalty tax. IRA Owners requesting a redemption of Fund
Shares  will be  required  to  provide a written  statement  as to  whether  the
proceeds  of the  redemption  will be subject to a penalty  tax and,  if not, to
identify the specific  exception  upon which the IRA Owner intends to rely.  The
information  provided  by the IRA Owner  will be  reflected  on the Form  1099-R
issued  to the IRA  Owner  and  filed  with  the  Internal  Revenue  Service  in
connection  with the redemption as well as forming the basis for redemption as a
Qualified IRA Redemption.  The Fund may require additional evidence, such as the
opinion of a certified  public  accountant or tax attorney,  that any particular
redemption  will not be subject to any penalty  tax. IRA OWNERS  SHOULD  CONSULT
THEIR TAX ADVISERS REGARDING THE TAX CONSEQUENCES OF ANY REDEMPTION.

   Some of the  exceptions to the 10% penalty taxes are  described  below.  This
description  is  intended  to  provide  only a brief  summary  of the  principal
exceptions to the additional tax imposed on early  withdrawals under the current
provisions of the Code,  which may change from time to time. The Fund intends to
conform the definition of Qualified IRA Redemptions to changes in applicable tax
laws;  however,  the Fund reserves the right to continue to define Qualified IRA
Redemptions by reference to Code provisions now in effect or otherwise to define
such phrase independently of future Code provisions.

TRADITIONAL  IRAS,  SEP-IRAS AND SIMPLE IRAS -- In general,  the 10% penalty tax
imposed by section  72(t) of the Code will not apply to the  following  types of
distributions from a Traditional IRA, SEP-IRA or SIMPLE IRA:

1.   Distributions  made on or after the date on which the IRA Owner attains age
     59 1/2;

2.   Distributions  made to a beneficiary (or to the estate of the IRA Owner) on
     or after the death of the IRA Owner;

3.   Distributions  attributable  to the IRA Owner's being  disabled  within the
     meaning of section 72(m)(7) of the Code;

4.   Distributions made to the IRA Owner to the extent such distributions do not
     exceed the amount of unreimbursed  medical  expenses allowed as a deduction
     under section 213 of the Code;

5.   Distributions to unemployed individuals to the extent such distributions do
     not exceed the amount paid for medical  insurance  as  described in section
     213(d)(1)(D)  of the  Code for the IRA  Owner,  and his or her  spouse  and
     dependents;

6.   Distributions  to an IRA  Owner to the  extent  such  distributions  do not
     exceed  the  qualified  higher  education  expenses,  as defined in section
     72(t)(7), for the IRA Owner;

7.   Distributions  to an IRA Owner that are used to acquire a first  home,  and
     that meet the definition of "qualified first-time homebuyer  distributions"
     under section 72(t) (8) of the Code; and

8.   Distributions  that are part of a series of  substantially  equal  periodic
     payments made at least  annually for the life (or life  expectancy)  of the
     IRA Owner, or the joint lives (or life  expectancies)  of the IRA Owner and
     his or her designated beneficiary.

ROTH IRAS -- With  respect  to a Roth IRA,  all  "qualified  distributions"  are
excluded from gross income and,  therefore,  from the 10% penalty tax imposed by
section 72(t). In general, qualified distributions from a Roth IRA include:

1.   Distributions  made on or after the date on which the IRA Owner attains age
     59 1/2;

2.   Distributions  made to a beneficiary (or to the estate of the IRA Owner) on
     or after the death of the IRA Owner;

3.   Distributions  attributable  to the IRA Owner's being  disabled  within the
     meaning of section 72(m)(7) of the Code; and

4.   Distributions  to an IRA Owner that are used to acquire a first  home,  and
     that meet the definition of "qualified first-time homebuyer  distributions"
     under section 72(t) (8) of the Code.

   However,  a  distribution  will not be a qualified  distribution,  even if it
otherwise meets the definition, if it is made within the 5-year period beginning
with the first taxable year for which the IRA Owner made a  contribution  to the
Roth IRA (or such person's  spouse made a contribution to a Roth IRA established
for the IRA  Owner).  Special  rules  apply with  respect  to  certain  types of
rollovers.

   To the extent a distribution from a Roth IRA is not a qualified distribution,
either  because it does not meet the definition of a qualified  distribution  in
the first instance,  or because it is made within the five-year period described
in section  408A(d)(2)(B),  the  portion  of the  distribution  that  represents
earnings  will be  subject  to tax in  accordance  with  section 72 of the Code,
including the 10% penalty tax imposed under section 72(t).  The same  exceptions
to the penalty  tax that apply to  Traditional  IRAs will apply to  nonqualified
distributions from Roth IRAs.

   In the  event  of a  nonqualified  distribution  from a Roth  IRA,  only  the
earnings  in the  account are  subject to tax;  contributions  may be  recovered
tax-free  (since no  deduction  is permitted  for such  contributions).  Section
408A(d) provides that  distributions from Roth IRAs are considered to come first
from  contributions,  to the extent that  distributions  do not exceed the total
amount of contributions.

KEOGH PLANS -- In general,  the 10% penalty tax imposed by section  72(t) of the
Code will not apply to the following types of  distributions  from a Traditional
IRA:

1.   Distributions  made on or after the date on which the IRA Owner attains age
     59 1/2;

2.   Distributions  made to a beneficiary (or to the estate of the IRA Owner) on
     or after the death of the IRA Owner;

3.   Distributions  attributable  to the IRA Owner's being  disabled  within the
     meaning of section 72(m)(7) of the Code;

4.   Distributions made to the IRA Owner after separation from service after age
     55;

5.   Distributions to unemployed individuals to the extent such distributions do
     not  exceed  the  amount of  unreimbursed  medical  expenses  allowed  as a
     deduction under section 213 of the Code;

6.   Distributions  to an alternate payee (e.g., a former spouse)  pursuant to a
     qualified domestic relations order; and

7.   Distributions  that are part of a series of  substantially  equal  periodic
     payments made at least  annually for the life (or life  expectancy)  of the
     IRA Owner, or the joint lives (or life  expectancies)  of the IRA Owner and
     his or her designated beneficiary.

EDUCATION  IRAS --  Distributions  from an education  IRA are included in income
unless the qualified higher education expenses of the designated beneficiary are
equal to or greater than the amount of such distributions.  In addition, certain
special  rules  are  provided  that  permit  certain  rollovers  or  changes  in
beneficiaries. Any distribution that is subject to tax under section 530 is also
subject to the 10% penalty tax imposed by section  530(d)(4).  Thus, in general,
any  distribution  from an  education  IRA that  exceeds the amount of qualified
higher education  expenses of the designated  beneficiary will be subject to the
10% penalty tax.

contemplated  by the Advisory  Agreement and other  activities for the Portfolio
described in the Prospectus and this SAI without violation of the Glass-Steagall
Act or other  applicable  banking  laws or  regulations.  However,  counsel  has
pointed  out that  future  changes  in  either  Federal  or state  statutes  and
regulations  concerning the permissible  activities of banks or trust companies,
as well as future judicial or  administrative  decisions or  interpretations  of
present and future  statutes and  regulations,  might prevent Bankers Trust from
continuing to perform those services for the Portfolio. State laws on this issue
may  differ  from the  interpretations  of  relevant  Federal  law and banks and
financial  institutions may be required to register as dealers pursuant to state
securities law. If the circumstances  described above should change,  the Boards
of Trustees  would  review the  relationships  with  Bankers  Trust and consider
taking all actions necessary in the circumstances.

ORGANIZATION OF SECURITY INCOME FUND

The Articles of  Incorporation of Security Income Fund provides for the issuance
of shares of common stock in one or more classes or series.

   Security  Income Fund has authorized the issuance of an indefinite  number of
shares of capital stock of $1.00 part value and  currently  issues its shares in
eight series,  Corporate Bond Fund, Limited Maturity Bond Fund, U.S.  Government
Fund,  High Yield  Fund,  Emerging  Markets  Total  Return  Fund,  Global  Asset
Allocation  Fund,  Global High Yield Fund and  Capital  Preservation  Fund.  The
shares of each Series of Security  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.

   Each Series of Security  Income Fund  currently  issues two classes of shares
except  Capital  Preservation  Fund which issues three  classes of shares.  Each
class of shares participates  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
each Series of Security income Fund will be fully paid and nonassessable. Shares
may be exchanged as described under "Exchange Privilege," in the prospecting 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 Security  Income Fund vote  together  with each share having one vote.
Under certain  circumstances,  the shareholders of one series of Security Income
Fund could  control the outcome of these  votes.  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.

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

ORGANIZATION OF THE TRUST

BT Investment  Funds was organized on July 21, 1986,  under the name BT Tax-Free
Investment  Trust,  and assumed its current name on May 16, 1988.  The shares of
each series  participate  equally in the  earnings,  dividends and assets of the
particular  series. The Trusts may create and issue additional series of shares.
Each Trust's  Declaration of Trust permits the Trustees to divide or combine the
shares into a greater or lesser number of shares  without  thereby  changing the
proportionate  beneficial  interest in series.  Each share  represents  an equal
proportionate interest in a series with each other share. Shares when issued are
fully  paid and  non-assessable,  except as set forth  below.  Shareholders  are
entitled to one vote for each share held.

   Shares of the Trust do not have  cumulative  voting rights,  which means that
holders of more than 50% of the shares  voting for the  election of Trustees can
elect all Trustees.  Shares are transferable but have no preemptive,  conversion
or subscription rights. Shareholders generally vote by Fund, except with respect
to the election of Trustees and the ratification of the selection of independent
accountants.

   Massachusetts   law   provides   that   shareholders   could  under   certain
circumstances  be held  personally  liable  for the  obligations  of the  Trust.
However,  the Trust's Declaration of Trust disclaims  shareholder  liability for
acts or obligations of the Trust and requires that notice of this  disclaimer be
given in each  agreement,  obligation or instrument  entered into or executed by
the Trust or a Trustee.  The  Declaration of Trust provides for  indemnification
from the Trust's  property for all losses and expenses of any  shareholder  held
personally  liable  for  the  obligations  of the  Trust.  Thus,  the  risk of a
shareholder's  incurring  financial loss on account of shareholder  liability is
limited to  circumstances  in which the Trust itself would be unable to meet its
obligations,  a possibility  that the Trust believes is remote.  Upon payment of
any liability  incurred by the Trust, the shareholder  paying the liability will
be entitled to reimbursement  from the general assets of the Trust. The Trustees
intend to conduct the operations of the Trust in a manner so as to avoid, as far
as possible,  ultimate  liability of the  shareholders  for  liabilities  of the
Trust.

   Whenever a Trust is requested to vote on matters  pertaining  to a Portfolio,
the  Trust  will  vote its  shares  without a  meeting  of  shareholders  of the
respective  Fund if the proposal is one, which if made with respect to the Fund,
would not require the vote of shareholders of the Fund as long as such action is
permissible  under  applicable  statutory and regulatory  requirements.  For all
other matters  requiring a vote, a Trust will hold a meeting of  shareholders of
its respective  Fund and, at the meeting of the investors in the Portfolio,  the
Trust  will  cast all of its  votes in the same  proportion  as votes in all its
shares  at the  Portfolio  meeting,  other  investors  with a  greater  pro rata
ownership of the Portfolio could have effective voting control of the operations
of the Portfolio.

TAXATION

TAXATION OF THE FUND -- The Fund intends to qualify  annually to be treated as a
regulated investment company under the Code. To qualify for that treatment,  the
Fund must, among other things,  (a) derive at least 90% of its gross income each
taxable year from dividends, interest, payments with respect to securities loans
and  gains  from  the  sale  or  other  disposition  of  securities  or  foreign
currencies,  or other income  (including gains from options,  futures or forward
contracts)  derived with respect to its business of investing in  securities  or
those currencies (the "Income Requirement"), (b) diversify its holdings so that,
at the end of each quarter of its taxable year, (i) at least 50% of the value of
its assets is represented by cash and cash items (including  receivables),  U.S.
government  securities,  securities of other regulated  investment companies and
other  securities,  with such other  securities of any one issuer  limited to an
amount  not  greater  than 5% of the value of the  Fund's  total  assets and not
greater than 10% of the issuer's outstanding voting securities and (ii) 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),  and (c)  distribute for each taxable year at
least 90% of its  investment  company  taxable income  (generally  consisting of
interest,  dividends  and the  excess of net  short-term  capital  gain over net
long-term capital loss).

   The Fund will be subject  to a  nondeductible  4%  federal  excise tax to the
extent it fails to distribute by the end of any calendar year  substantially all
of its  ordinary  income  for that  year and  capital  gain net  income  for the
one-year period ending on October 31 of that year, plus any undistributed amount
from the prior year.

   The  Fund,  as an  investor  in  the  Portfolio,  will  be  deemed  to  own a
proportionate share of the Portfolio's assets, and to earn a proportionate share
of the  Portfolio's  income,  for  purposes  of  determining  whether  the  Fund
satisfies  all the  requirements  described  above  to  qualify  as a  regulated
investment  company.   See  the  next  section  for  a  discussion  of  the  tax
consequences to the Fund of hedging transactions engaged in by the Portfolio.

TAXATION  OF THE  PORTFOLIO  -- The  Portfolio  will be  treated  as a  separate
partnership  for federal income tax purposes and will not be a "publicly  traded
partnership."  As a result,  the Portfolio will not be subject to federal income
tax. Instead,  the Fund and other investors in the Portfolio will be required to
take into  account,  in computing  their  federal  income tax  liability,  their
respective  shares of the  Portfolio's  income,  gains,  losses,  deductions and
credits,  without  regard to whether they have  received any cash  distributions
from the  Portfolio.  The Portfolio  also will not be subject to state income or
franchise tax.

   Because, as noted above, the Fund will be deemed to own a proportionate share
of the Portfolio's  assets, and to earn a proportionate share of the Portfolio's
income, for purposes of determining  whether the Fund satisfies the requirements
to qualify as a regulated  investment company,  the Portfolio intends to conduct
its operations so that the Fund will be able to satisfy all those requirements.

   Distributions  received by the Fund from the Portfolio (whether pursuant to a
partial or complete  withdrawal or otherwise)  generally  will not result in the
Fund's recognizing any gain or loss for federal income tax purposes, except that
(a) gain will be recognized to the extent any cash that is  distributed  exceeds
the Fund's basis for its interest in the  Portfolio  prior to the  distribution,
(b) income or gain will be realized if the distribution is in liquidation of the
Fund's entire interest in the Portfolio and includes a disproportionate share of
any unrealized  receivables held by the Portfolio,  and (c) gain or loss will be
recognized  if  a  liquidation  distribution  consists  solely  of  cash  and/or
unrealized  receivables.  The Fund's  basis for its  interest  in the  Portfolio
generally  will equal the amount of cash and the basis of any  property the Fund
invests in the Portfolio,  increased by the Fund's share of the  Portfolio's net
income  and gains and  decreased  by (i) the amount of any cash and the basis of
any  property  distributed  from the  Portfolio  to the Fund and (ii) the Fund's
share of the Portfolio's losses, if any.

   The  Portfolio's  use of hedging  strategies,  such as writing  (selling) and
purchasing  options  and futures  contracts,  involves  complex  rules that will
determine  for  income  tax  purposes  the  amount,   character  and  timing  of
recognition of the gains and losses it realizes in connection  therewith.  Gains
from options and futures  contracts derived by the Portfolio with respect to its
business of investing in securities  will qualify as permissible  income for the
Fund under the Income Requirement.

   Certain  futures and foreign  currency  contracts in which the  Portfolio may
invest may be subject to section 1256 of the Code  ("section  1256  contracts").
Any section  1256  contracts  held by the  Portfolio  at the end of each taxable
year, other than contracts  subject to a "mixed  straddle"  election made by the
Portfolio,  must be "marked-to-market"  (that is, treated as having been sold at
that time for their fair market value) for federal income tax purposes, with the
result  that  unrealized  gains or losses  will be treated  as though  they were
realized.  Sixty  percent  of any net gain or loss  recognized  on these  deemed
sales, and 60% of any net realized gain or loss from any actual sales of section
1256  contracts,  will be treated as  long-term  capital  gain or loss,  and the
balance  will be  treated  as  short-term  capital  gain or loss.  Section  1256
contracts  also  may be  marked-to-market  for  purposes  of the 4%  excise  tax
mentioned above.

   Code section 1092  (dealing with  straddles)  also may affect the taxation of
options and futures  contracts in which the Portfolio  may invest.  Section 1092
defines a "straddle" as offsetting  positions with respect to personal property;
for these purposes,  options and futures contracts are personal property.  Under
that  section,  any loss  from  the  disposition  of a  position  in a  straddle
generally  may be deducted  only to the extent the loss  exceeds the  unrealized
gain on the offsetting position(s) of the straddle; in addition, these rules may
apply to postpone the  recognition  of loss that  otherwise  would be recognized
under the  mark-to-market  rules discussed above. The regulations  under section
1092 also provide certain "wash sale" rules, which apply to transactions where a
position is sold at a loss and a new  offsetting  position is acquired  within a
prescribed  period,  and "short  sale" rules  applicable  to  straddles.  If the
Portfolio  makes  certain  elections,   the  amount,  character  and  timing  of
recognition of gains and losses from the affected  straddle  positions  would be
determined under rules that vary according to the elections made. Because only a
few of the regulations  implementing  the straddle rules have been  promulgated,
the tax consequences to the Portfolio of straddle  transactions are not entirely
clear.

   If the Portfolio has an  "appreciated  financial  position" -- generally,  an
interest (including an interest through an option,  futures or forward contract,
or short sale) with respect to any debt instrument  (other than "straight debt")
or  partnership  interest  the fair market  value of which  exceeds its adjusted
basis -- and  enters  into a  "constructive  sale" of the same or  substantially
similar  property,  the Portfolio  will be treated as having made an actual sale
thereof,  with  the  result  that  gain  will  be  recognized  at that  time.  A
constructive  sale  generally  consists of a short sale, an offsetting  notional
principal  contract,  or a  futures  or  forward  contract  entered  into by the
Portfolio or a related person with respect to the same or substantially  similar
property.  In addition,  if the appreciated financial position is itself a short
sale or such a contract, acquisition of the underlying property or substantially
similar  property will be deemed a  constructive  sale.  The foregoing  will not
apply,  however, to any transaction during any taxable year that otherwise would
be treated as a  constructive  sale if the  transaction is closed within 30 days
after the end of that year and the  Portfolio  holds the  appreciated  financial
position  unhedged for 60 days after that closing (I.E.,  at no time during that
60-day period is the Portfolio's risk of loss regarding that position reduced by
reason of certain specified  transactions with respect to substantially  similar
or  related  property,  such as having an  option to sell,  being  contractually
obligated  to  sell,   making  a  short  sale  or  granting  an  option  to  buy
substantially identical stock or securities).

OTHER TAXATION -- The  investment by the Fund in the Portfolio  should not cause
the Fund to be liable for any income or franchise tax in the State of New York.

   The Portfolio is organized as a New York trust.  The Portfolio is not subject
to any income or franchise tax in the State of New York or the State of Kansas.

FOREIGN WITHHOLDING TAXES -- Income received and gains realized by the Portfolio
from sources  within foreign  countries may be subject to withholding  and other
taxes imposed by those countries that would reduce the yield and/or total return
on its  securities.  Tax conventions  between  certain  countries and the United
States may reduce or eliminate  these foreign taxes,  however,  and many foreign
countries  do not impose  taxes on capital  gains in respect of  investments  by
foreign investors.

FINANCIAL STATEMENTS

The Portfolio did not begin operations until ______________________ and the Fund
did not begin operations until May of 1999. Therefore, neither the Portfolio nor
the Fund have audited financial statements at this time.

                                    APPENDIX
- --------------------------------------------------------------------------------

DESCRIPTION OF MOODY'S CORPORATE BOND RATINGS

Aaa -- Bonds  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 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 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 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  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 rated B generally  lack  characteristics  of a 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  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  rated Ca  represent  obligations  which are  speculative  in a high
degree. Such issues are often in default or have other marked short-comings.

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

   Moody's  applies  numerical  modifiers,  1, 2, and 3, in each generic  rating
classification  from Aa through B in its corporate  bond 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 the  modifier 3
indicates that the issue ranks in the lower end of its generic rating category.

DESCRIPTION OF S&P'S CORPORATE BOND RATINGS

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

AA -- Debt  rated  AA has a very  strong  capacity  to pay  interest  and  repay
principal and differs from the higher-rated issues only in small degree.

A -- Debt rated A has a strong  capacity to pay  interest  and repay  principal,
although it is somewhat more  susceptible  to the adverse  effects of changes in
circumstances and economic conditions.

BBB -- Debt rated BBB is regarded as having an adequate capacity to pay interest
and  repay  principal.   Whereas  it  normally  exhibits   adequate   protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to weakened capacity to pay interest and repay principal for debt
in this category than in higher-rated categories.

BB -- Debt  rate BB has less  near-term  vulnerability  to  default  than  other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse  business,  financial,  or  economic  conditions  which  could  lead  to
inadequate capacity to meet timely interest and principal payments.

B -- Debt rated B has a greater  vulnerability  to default but currently has the
capacity to meet interest payments and principal  repayments.  Adverse business,
financial,  or economic conditions will likely impair capacity or willingness to
pay interest and repay  principal.  The B rating  category is also used for debt
subordinated to senior debt that is assigned an actual or implied BB- rating.

CCC -- Debt rated CCC has a currently identifiable vulnerability to default, and
is dependent upon favorable business, financial, and economic conditions to meet
timely  payment of interest and repayment of principal.  In the event of adverse
business,  financial,  or  economic  conditions,  it is not  likely  to have the
capacity to pay interest and repay principal.

CC -- Debt rated CC is  typically  applied to debt  subordinated  to senior debt
which is assigned an actual or implied CCC debt rating.

C -- The rating C is typically applied to debt subordinated to senior debt which
is assigned an actual or implied CCC- debt  rating.  The C rating may be used to
cover a situation  where a  bankruptcy  petition has been filed but debt service
payments are continued.

CI -- The rating CI is reserved  for income  bonds on which no interest is being
paid.

D -- Debt  rated D is in payment  default.  The D rating  category  is used when
interest payments or principal payments are not made on the date due even if the
applicable grace period has not expired,  unless S&P believes that such payments
will be made during such grace  period.  The D rating will also be used upon the
filing of a bankruptcy petition if debt service payments are jeopardized.

   Plus (+) or minus (-):  The ratings from "AA" to "CCC" may be modified by the
addition  of a plus or minus  sign to show  relative  standing  within the major
rating categories.

DUFF & PHELPS' LONG-TERM DEBT RATINGS

AAA -- Highest  credit  quality.  The risk  factors are  negligible,  being only
slightly more than for risk-free U.S. Treasury debt.

AA+,  AA, AA- -- High credit  quality.  Protection  factors are strong.  Risk is
modest but may vary slightly from time to time because of economic conditions.

A+, A, A- -- Protection factors are average but adequate.  However, risk factors
are more variable and greater in periods of economic stress.

BBB+,  BBB,  BBB- --  Below-average  protection  factors  but  still  considered
sufficient  for  prudent  investment.  Considerable  variability  in risk during
economic cycles.

BB+, BB, BB- -- Below investment grade but deemed likely to meet obligation when
due. Present or prospective  financial protection factors fluctuate according to
industry  conditions or company  fortunes.  Overall  quality may move up or down
frequently within this category.

B+, B, B- -- Below  investment  grade and possessing risk that  obligations will
not  be met  when  due.  Financial  protection  factors  will  fluctuate  widely
according to economic  cycles,  industry  conditions  and/or  company  fortunes.
Potential exists for frequent changes in the rating within this category or into
a higher or lower rating grade.

CCC -- Well below investment-grade  securities.  Considerable uncertainty exists
as to timely payment of principal,  interest or preferred dividends.  Protection
factors   are   narrow   and   risk   can  be   substantial   with   unfavorable
economic/industry conditions, and/or with unfavorable company developments.

DD -- Defaulted  debt  obligations.  Issuer failed to meet  scheduled  principal
and/or interest payments.

DP -- Preferred stock with dividend arrearages.

DESCRIPTION OF MOODY'S SHORT-TERM DEBT RATINGS

Issuers  rated  Prime-1 (or  related  supporting  institutions)  have a superior
capacity for repayment of short-term promissory  obligations.  Prime-1 repayment
capacity will normally be evidenced by the  following  characteristics:  leasing
market positions in well-established  industries;  high rates of return on funds
employed;  conservative capitalization structures with moderate reliance on debt
and  ample  asset  protection;  broad  margins  in  earnings  coverage  of fixed
financial charges and high internal cash generation;  well-established access to
a range of financial markets and assured sources of alternate liquidity.

   Issuers  rated  Prime-2 (or related  supporting  institutions)  have a strong
capacity for repayment of short-term promissory obligations.  This will normally
be evidenced by many of the characteristics  cited above but to a lesser degree.
Earnings  trends and  coverage  ratios,  while  sound,  will be more  subject to
variation. Capitalization characteristics,  while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

   Issuers rates Prime-3 (or related supporting institutions) have an acceptable
capacity  for  repayment of  short-term  promissory  obligations.  The effect of
industry   characteristics  and  market  composition  may  be  more  pronounced.
Variability in earnings and  profitability may result in changes in the level of
debt protection  measurements  and the requirement for relatively high financial
leverage. Adequate alternate liquidity is maintained.

DESCRIPTION OF S&P SHORT-TERM ISSUER CREDIT RATINGS

A-1 -- An  obligor  rated  `A-1'  has  STRONG  capacity  to meet  its  financial
commitments.  It is rated in the highest  category by Standard & Poor's.  Within
this  category,  certain  obligors  are  designated  with a plus sign (+).  This
indicates  that the  obligor's  capacity to meet its  financial  commitments  is
EXTREMELY STRONG.

A-2 -- An obligor  rated `A-2' has  SATISFACTORY  capacity to meet its financial
commitments.  However, it is somewhat more susceptible to the adverse effects of
changes in  circumstances  and economic  conditions than obligors in the highest
rating category.

A-3 -- An  obligor  rated  `A-3' has  ADEQUATE  capacity  to meet its  financial
obligations.  However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened  capacity of the obligor to meet its financial
commitments.

DESCRIPTION OF DUFF & PHELPS' COMMERCIAL PAPER RATINGS

D-1+ -- Highest  certainty of timely payment.  Short term  liquidity,  including
internal  operating  factors and/or access to alternative  sources of funds,  is
outstanding,  and  safety  is just  below  risk  free  U.S.Treasury  short  term
obligations.

D-1 -- Very high certainty of timely  payment.  Liquidity  factors are excellent
and supported by good fundamental protection factors. Risk factors are minor.

D-1- -- High  certainty  of timely  payment.  Liquidity  factors  are strong and
supported by good fundamental protection factors. Risk factors are very small.

D-2  --  Good  certainty  of  timely  payment.  Liquidity  factors  and  company
fundamentals  are  sound.  Although  ongoing  funding  needs may  enlarge  total
financing  requirements,  access to capital  markets is good.  Risk  factors are
small.

D-3 -- Satisfactory  liquidity and other protection factors qualify issues as to
investment  grade.  Risk  factors  are  larger and  subject  to more  variation.
Nevertheless, timely payment is expected.

DESCRIPTION OF MOODY'S INSURANCE FINANCIAL STRENGTH RATINGS

Aaa -- Insurance companies rated Aaa offer exceptional financial security. While
the financial  strength of these companies is likely to change,  such changes as
can be  visualized  are most  unlikely  to  impair  their  fundamentally  strong
position.

Aa -- Insurance companies rated Aa offer excellent financial security.  Together
with the Aaa  group  they  constitute  what are  generally  known as high  grade
companies.  They are rated  lower than Aaa  companies  because  long-term  risks
appear somewhat larger.

A --  Insurance  companies  rated  A offer  good  financial  security.  However,
elements may be present which suggest a susceptibility to impairment sometime in
the future.

Baa -- Insurance companies rated Baa offer adequate financial security. However,
certain  protective  elements  may  be  lacking  or  may  be  characteristically
unreliable over any great length of time.

Ba -- Insurance companies rated Ba offer questionable financial security.  Often
the  ability of these  companies  to meet  policyholder  obligations  maybe very
moderate and thereby not well safeguarded in the future.

B -- Insurance  companies  rated B offer poor financial  security.  Assurance of
punctual  payment of  policyholder  obligations  over any long period of time is
small.

Caa -- Insurance  companies rated Caa offer very poor financial  security.  They
may be in  default  on their  policyholder  obligations  or there may be present
elements of danger with respect to punctual payment of policyholder  obligations
and claims.

Ca -- Insurance companies rated Ca offer extremely poor financial security. Such
companies are often in default on their  policyholder  obligations or have other
marked shortcomings.

C -- Insurance companies rated C are the lowest rated class of insurance company
and can be  regarded  as  having  extremely  poor  prospects  of  ever  offering
financial security.

   Numeric modifiers:  Numeric modifiers are used to refer to the ranking within
the group -- one being the  highest and three  being the  lowest.  However,  the
financial strength of companies within a generic rating symbol (Aa, for example)
is broadly the same.

DESCRIPTION OF S&P CLAIMS PAYING ABILITY RATING DEFINITIONS

SECURE RANGE -- AAA to BBB

"AAA" -- Superior financial security on an absolute and relative basis. Capacity
to meet policyholder obligations is overwhelming under a variety of economic and
underwriting conditions.

"AA" -- Excellent financial security.  Capacity to meet policyholder obligations
is strong under a variety of economic and underwriting conditions.

"A" -- Good financial security, but capacity to meet policyholder obligations is
somewhat susceptible to adverse economic and underwriting conditions.

"BBB"  --  Adequate  financial  security,  but  capacity  to  meet  policyholder
obligations is susceptible to adverse economic and underwriting conditions.

VULNERABLE RANGE -- BB to CCC

"BB" -- Financial  security may be adequate,  but capacity to meet  policyholder
obligations,  particularly with respect to long-term or "long-tail" policies, is
vulnerable to adverse economic and underwriting conditions.

"B" --  Vulnerable  financial  security.  Currently  able to  meet  policyholder
obligations,  but  capacity to meet  policyholder  obligations  is  particularly
vulnerable to adverse economic and underwriting conditions.

"CCC" -- Extremely  vulnerable  financial  security.  Continued capacity to meet
policyholder  obligations is highly  questionable  unless favorable economic and
underwriting conditions prevail.

"R" --  Regulatory  action.  As of the  date  indicated,  the  insurer  is under
supervision  of insurance  regulators  following  rehabilitation,  receivership,
liquidation,  or any other action that  reflects  regulatory  concern  about the
insurer's  financial  condition.  Information  on this status is provided by the
National  Association of Insurance  Commissioners  and other regulatory  bodies.
Although  believed to be accurate,  this information is not guaranteed.  The "R"
rating does not apply to insurers  subject only to nonfinancial  actions such as
market conduct violations.

   Plus  (+) or  minus  (-)  Ratings  from  "AA" to "B" may be  modified  by the
addition  of a plus or minus  sign to show  relative  standing  within the major
rating categories.

DUFF & PHELPS' CLAIMS PAYING ABILITY RATINGS

AAA -- Highest claims paying ability. Risk factors are negligible.

AA+, AA, AA- -- Very high claims paying ability.  Protection factors are strong.
Risk is  modest,  but  may  vary  slightly  over  time  due to  economic  and/or
underwriting conditions.

A+, A, A- -- High  claims  paying  ability.  Protection  factors are average and
there is an expectation of variability in risk over time due to economic  and/or
underwriting conditions.

BBB+,  BBB,  BBB- -- Adequate  claims  paying  ability.  Protection  factors are
adequate.  There is  considerable  variability in risk over time due to economic
and/or underwriting conditions.

BB+, BB, BB- -- Uncertain  claims paying ability and less than investment  grade
quality.  However,  the company is deemed likely to meet these  obligations when
due.  Protection  factors  will vary  widely  with  changes in  economic  and/or
underwriting conditions.

B+, B, B- -- Possessing risk that  policyholder and  contractholder  obligations
will not be paid when due.  Protection  factors will vary widely with changes in
economic and underwriting conditions or company fortunes.

CCC  --  There  is  substantial  risk  that   policyholder  and   contractholder
obligations  will not be paid  when  due.  Company  has been or is  likely to be
placed under state insurance department supervision.

DD -- Company is under an order of liquidation.

ITEM 26.  NUMBER OF HOLDERS OF SECURITIES AS OF FEBRUARY 1, 1999.

ITEM 27.  INDEMNIFICATION.

          A policy of insurance covering Security Management  Company,  LLC, its
          affiliate  Security  Distributors,  Inc.,  and  all of the  registered
          investment  companies  advised by  Security  Management  Company,  LLC
          insures the  Registrant's  directors  and officers  against  liability
          arising by reason of an alleged breach of duty caused by any negligent
          act, error or accidental omission in the scope of their duties.

          Paragraph 30 of the Registrant's  Bylaws, as amended February 3, 1995,
          provides in relevant part as follows:

               30. INDEMNIFICATION AND LIABILITY OF DIRECTORS AND OFFICERS. Each
               person who is or was a Director or officer of the  Corporation or
               is or was serving at the request of the Corporation as a Director
               or  officer  of  another   corporation   (including   the  heirs,
               executors,  administrators  and estate of such  person)  shall be
               indemnified  by the  Corporation  as of right to the full  extent
               permitted or  authorized  by the laws of the State of Kansas,  as
               now in effect and is hereafter  amended,  against any  liability,
               judgment,  fine,  amount  paid in  settlement,  cost and  expense
               (including  attorney's  fees) asserted or threatened  against and
               incurred by such person in his/her  capacity as or arising out of
               his/her status as a Director or officer of the Corporation or, if
               serving at the  request  of the  Corporation,  as a  Director  or
               officer of another corporation.  The indemnification  provided by
               this bylaw  provision  shall not be exclusive of any other rights
               to which those  indemnified may be entitled under the Articles of
               Incorporation, under any other bylaw or under any agreement, vote
               of  stockholders  or  disinterested  directors or otherwise,  and
               shall not limit in any way any right  which the  Corporation  may
               have to make different or further indemnification with respect to
               the same or different persons or classes of persons.

               No  person  shall be  liable  to the  Corporation  for any  loss,
               damage,  liability  or expense  suffered  by it on account of any
               action  taken or omitted to be taken by him/her as a Director  or
               officer  of the  Corporation  or of any other  corporation  which
               he/she  serves as a Director  or  officer  at the  request of the
               Corporation, if such person (a) exercised the same degree of care
               and  skill as a  prudent  man  would  have  exercised  under  the
               circumstances in the conduct of his/her own affairs,  or (b) took
               or omitted to take such action in reliance upon advice of counsel
               for the  Corporation,  or for  such  other  corporation,  or upon
               statement made or information  furnished by Directors,  officers,
               employees  or  agents  of  the  Corporation,  or  of  such  other
               corporation,   which   he/she  had  no   reasonable   grounds  to
               disbelieve.

               In the  event  any  provision  of this  section  30  shall  be in
               violation of the Investment  Company Act of 1940, as amended,  or
               of  the  rules  and  regulations  promulgated  thereunder,   such
               provisions shall be void to the extent of such violations.

          On March 25, 1988, the  shareholders  approved the Board of Directors'
          recommendation  that the  Articles  of  Incorporation  be  amended  by
          adopting the following Article Fifteenth:

               "A director shall not be personally  liable to the corporation or
               to its  stockholders for monetary damages for breach of fiduciary
               duty  as a  director,  provided  that  this  sentence  shall  not
               eliminate nor limit the liability of a director:

               A.  for  any  breach  of  his  or  her  duty  of  loyalty  to the
                   corporation or to its stockholders;

               B.  for acts or  omissions  not in good  faith  or which  involve
                   intentional  misconduct or a knowing violation of law;

               C.  for any unlawful dividend, stock purchase or redemption under
                   the provisions of Kansas Statutes  Annotated (K.S.A.) 17-6424
                   and amendments thereto; or

               D.  for any  transaction  from  which  the  director  derived  an
                   improper personal benefit."

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

                            ARTICLES OF INCORPORATION

                                       OF

                            SECURITY BOND FUND, INC.


          We, the undersigned incorporators, hereby associate ourselves together
to form and  establish a  corporation  for profit under the laws of the State of
Kansas.

          FIRST: The name of the corporation is:

          SECOND:  The location of its  registered  office in Kansas is Security
Benefit Life Building, 700 Harrison Street, Topeka, Kansas 66603.

          THIRD:  The name and address of its registered agent in Kansas is Will
J. Miller,  Jr.,  Security Benefit Life Building,  700 Harrison Street,  Topeka,
Kansas 66603.

          FOURTH: This corporation is organized for profit and the nature of its
business, objects and purposes to be transacted, promoted and carried on, is:

          (1) To engage in the business of an investment company and mutual fund
     and to hold, invest and reinvest its funds, and in connection  therewith to
     hold  part or all of its  funds  in  cash,  and to  purchase  or  otherwise
     acquire, hold for investment or otherwise, trade, purchase on margin, sell,
     sell short, assign, pledge, hypothecate,  negotiate,  transfer, exchange or
     otherwise dispose of or turn to account or realize upon,  securities (which
     term  "securities"  shall  for  the  purposes  of  this  Article,   without
     limitation  of the  generality  thereof,  be deemed to include  any stocks,
     bonds, shares, debentures,  notes, mortgages or other obligations,  and any
     certificates,  receipts,  warrants or other instruments representing rights
     to  receive,   purchase  or  subscribe  for  the  same,  or  evidencing  or
     representing any other rights or interests  therein,  or in any property or
     assets)   created   or  issued  by  any   persons,   firms,   associations,
     corporations,  syndicates,  combinations,   organizations,  governments  or
     subdivisions   thereof;  and  to  exercise,  as  owner  or  holder  of  any
     securities, all rights, powers and privileges in respect thereof; and to do
     any and all acts and things for the preservation,  protection,  improvement
     and enhancement in value of any and all such securities.

          (2) To issue and sell shares of its own capital  stock in such amounts
     and on such terms and conditions,  for such purposes and for such amount or
     kind of consideration (including,  without limitation thereof,  securities)
     now or  hereafter  permitted  by the laws of Kansas,  by these  Articles of
     Incorporation and the Bylaws of the corporation,  as its Board of Directors
     may determine.

          (3) To  purchase  or  otherwise  acquire,  redeem,  hold,  dispose of,
     resell,   transfer,  or  reissue  (all  without  any  vote  or  consent  of
     stockholders of the corporation) shares of its capital stock, in any manner
     and to the extent now or  hereafter  permitted  by the laws of the State of
     Kansas,  by  these  Articles  of  Incorporation  and by the  Bylaws  of the
     corporation,  provided that shares of its own capital stock belonging to it
     shall not be voted directly or indirectly.

          (4) To conduct its business in all its branches at one or more offices
     in Kansas and elsewhere in any part of the world,  without  restriction  or
     limit as to extent.

          (5) To carry out all or any of the foregoing  purposes as principal or
     agent,  and alone or with  associates  or, to the extent  now or  hereafter
     permitted by the laws of Kansas,  as a member of, or as the owner or holder
     of any  stock  of,  or  shares  of  interest  in,  any  firm,  association,
     corporation,  trust or syndicate;  and in  connection  therewith to make or
     enter into such deeds or contracts with any persons,  firms,  associations,
     corporations,  syndicates,  governments or sub-divisions thereof, and to do
     such acts and things and to exercise such powers as a natural  person could
     lawfully make, enter into, do or exercise.

          (6) To do any and all such further acts and things and to exercise any
     and all such  further  powers as may be  necessary,  incidental,  relative,
     conducive, appropriate or desirable for the accomplishment, carrying out or
     attainment of all or any of the foregoing purposes.

          It is the intention  that each of the  purposes,  specified in each of
the paragraphs of this Article FOURTH, shall be in no wise limited or restricted
by reference to or inference from the terms of any other paragraph, but that the
purposes  specified in each of the  paragraphs  of this Article  FOURTH shall be
regarded as independent  objects,  purposes and powers.  The  enumeration of the
specific  purposes of this Article  FOURTH shall not be construed to restrict in
any manner the general  objects,  purposes and powers of this  corporation,  nor
shall the expression of one thing be deemed to exclude  another,  although it be
of like  nature.  The  enumeration  of  purposes  herein  shall not be deemed to
exclude or in any way limit by inference  any objects,  purposes or powers which
this  corporation  has power to exercise,  whether  expressly or by force of the
laws of the State of Kansas,  now or  hereafter  in effect,  or impliedly by any
reasonable construction of such laws.

          FIFTH:  The total  number of shares which the  corporation  shall have
authority to issue shall be 3,000,000  shares of capital stock,  each of the par
value  of  $1.00.  The  Board  of  Directors  shall  have  the  power to fix the
consideration  to be received by the corporation for any and all shares of stock

                              SECURITY INCOME FUND

The Board of Directors of Security  Income Fund  recommends that the Articles of
Incorporation  be amended  by  deleting  Article  Fifth in its  entirety  and by
inserting, in lieu therefor, the following new Article:

FIFTH:  The total  number of shares of stock  which the  corporation  shall have
authority to issue shall be Four Hundred Million  (400,000,000) shares of common
stock,  each of the par value of One  Dollar  ($1.00)  per  share.  The board of
directors of the  corporation is expressly  authorized to cause shares of common
stock of the corporation  authorized  herein to be issued in one or more classes
or series as may be established  from time to time by setting or changing in one
or more  respects the voting  powers,  rights,  qualifications,  limitations  or
restrictions  of such shares of stock and to increase or decrease  the number of
shares so authorized to be issued in any such class or series.

The following provisions are hereby adopted for the purpose of setting forth the
powers, rights, qualifications, limitations or restrictions of the capital stock
of the  corporation  (unless  provided  otherwise by the board of directors with

     of any class or series standing in the  stockholder's  name on the books of
     the  corporation  on the date,  fixed in  accordance  with the Bylaws,  for
     determination  of  stockholders  entitled to vote at such  meeting.  At all
     elections of  directors  each  stockholder  of any class or series shall be
     entitled  to as many votes as shall  equal the number of shares of stock of
     any class or series  multiplied  by the number of  directors to be elected,
     and  stockholders  may cast all of such votes for a single  director or may
     distribute  them among the  number to be voted  for,  or any two or more of
     them as they may see fit.

(2)  All  shares of stock of the  corporation  of any  class or series  shall be
     nonassessable.

(3)  No holder of any shares of stock of the  corporation of any class or series
     shall be  entitled  as such,  as a matter of  right,  to  subscribe  for or
     purchase  any  shares of stock of the  corporation  of any class or series,
     whether now or hereafter authorized or whether issued for cash, property or
     services or as a dividend or otherwise, or to subscribe for or purchase any
     obligations,   bonds,   notes,   debentures,   other  securities  or  stock

COUNTY OF SHAWNEE)

We, Michael J. Provines, President, and Brenda M. Luthi, Assistant Secretary, of
Security Income Fund, a corporation organized and existing under the laws of the
State of  Kansas,  and whose  registered  office is the  Security  Benefit  Life
Building, 700 Harrison Street, Topeka,  Shawnee,  Kansas, do hereby certify that
pursuant to the  authority  expressly  vested in the Board of  Directors  by the
provisions  of  the  corporation's  Articles  of  Incorporation,  the  Board  of
Directors of said  corporation  at a meeting duly  convened and held on the 23rd
day of July,  1993,  adopted  resolutions  establishing two new series of common
stock in addition to those series of common stock  currently being issued by the
corporation.  Resolutions  were also  adopted  which set forth the  preferences,
rights,  privileges and restrictions of the separate series of stock of Security
Income Fund, which resolutions are provided in their entirety as follows:

RESOLVED  that,  pursuant to the  authority  vested in the Board of Directors of
Security Income Fund by its Articles of Incorporation,  the officers of the Fund
are hereby  directed and  authorized to establish two new series of the Fund and
to  redesignate  the  existing  series.  The  existing  series shall be known as
Corporate  Bond  Series A and U.S.  Government  Series A. The new series  hereby
established shall be known as Corporate Bond Series B and U.S. Government Series
B. The  officers  of the Fund are hereby  directed  and  authorized  to allocate
100,000,000  $1.00 par value shares of the Fund's  authorized  capital  stock of
400,000,000 shares to each series.

FURTHER RESOLVED, that the preferences,  rights,  privileges and restrictions of
the shares of each series of Security Income Fund shall be as follows:

1.  Except as set forth below and as may be hereafter  established  by the Board
    of Directors of the corporation all shares of the corporation, regardless of
    series, shall be equal.

2.  At all meetings of stockholders each stockholder of the corporation shall be
    entitled  to one vote in person or by proxy on each  matter  submitted  to a
    vote at such meeting for each share of common  stock  standing in his or her
    name on the books of the  corporation on the date,  fixed in accordance with
    the  bylaws,  for  determination  of  stockholders  entitled to vote at such
    meeting. At all elections of directors each stockholder shall be entitled to
    as many votes as shall equal the number of shares of stock multiplied by the
    number of directors to be elected,  and he or she may cast all of such votes
    for a single  director or may  distribute  them among the number to be voted
    for,  or any two or more of them as he or she may see  fit.  Notwithstanding
    the foregoing, (i) if any matter is submitted to the stockholders which does
    not  affect  the  interest  of all  series,  then only  stockholders  of the
    affected  series  shall  be  entitled  to vote  and  (ii) in the  event  the
    Investment  Company Act of 1940,  as amended,  or the rules and  regulations
    promulgated  thereunder shall require a greater or different vote than would
    otherwise  be required  herein or by the  Articles of  Incorporation  of the
    corporation,  such greater or  different  voting  requirement  shall also be
    satisfied.

3.  (a)  The  corporation  shall  redeem  any  of its  shares  for which  it has
         received  payment in full that may be presented to the  corporation  on
         any date after the issue date of any such shares at the net asset value
         thereof,  such  redemption  and the valuation and payment in connection
         therewith  to  be  made  in  compliance  with  the  provisions  of  the
         Investment   Company  Act  of  1940  and  the  Rules  and   Regulations
         promulgated  thereunder  and with the  Rules  of Fair  Practice  of the
         National Association of Securities Dealers,  Inc., as from time to time
         amended.

    (b)  From and after the close of  business  on the day when the  shares  are
         properly  tendered for repurchase the owner shall, with respect of said
         shares,  cease to be a stockholder  of the  corporation  and shall have
         only the right to receive the repurchase  price in accordance  with the
         provisions  hereof.  The  shares so  repurchased  may,  as the Board of
         Directors  determines,  be held in the treasury of the  Corporation and
         may be resold,  or, if the laws of Kansas shall permit, may be retired.
         Repurchase of shares is conditional  upon the corporation  having funds
         or property legally available thereof.

4.  All shares of the corporation,  upon issuance and sale, shall be fully paid,
    nonassessable   and  redeemable.   Within  the  respective   series  of  the
    corporation,  all shares have equal voting,  participation  and  liquidation
    rights, but have no subscription or preemptive rights.

5.  (a)  Outstanding shares  of Corporate Bond  Series A and B  shall  represent
         a  stockholder  interest  in a  particular  fund of assets  held by the
         corporation  which fund shall be invested and  reinvested in accordance
         with  policies and  objectives  established  by the Board of Directors.
         Outstanding shares of U.S.  Government Series A and B shall represent a
         stockholder  interest  in a  particular  fund  of  assets  held  by the
         corporation  which fund shall be invested and  reinvested in accordance
         with policies and objectives established by the Board of Directors.

    (b)  All cash and other property  received by the corporation  from the sale
         of  shares of  Corporate  Bond  Series A and B and the U.S.  Government
         Series A and B, respectively, all securities and other property held as
         a result  of the  investment  and  reinvestment  of such cash and other
         property,  all revenues and income  received or receivable with respect
         to such cash, other property,  investments and  reinvestments,  and all
         proceeds  derived  from  the  sale,  exchange,   liquidation  or  other
         disposition  of  any  of  the  foregoing,  shall  be  allocated  to the
         Corporate  Bond  Series  A and B or U.S.  Government  Series A and B to
         which they relate and held for the benefit of the  stockholders  owning
         shares of such series.

    (c)  All losses,  liabilities  and  expenses of the  corporation  (including
         accrued  liabilities  and  expenses  and such  reserves as the Board of
         Directors may determine are appropriate) shall be allocated and charged
         to the series to which such loss,  liability or expense relates.  Where
         any loss,  liability  or expense  relates to more than one series,  the
         Board of Directors shall allocate the same between or among such series
         pro rata based on the  respective net asset values of such series or on
         such other basis as the Board of Directors deems appropriate.

    (d)  All  allocations  made  hereunder  by the Board of  Directors  shall be
         conclusive and binding upon all stockholders and upon the corporation.

6.  Each  share of stock of a series  shall have the same  preferences,  rights,
    privileges  and  restrictions  as each other share of stock of that  series.
    Each fractional  share of stock of a series  proportionately  shall have the
    same preferences, rights, privileges and restrictions as a whole share.

7.  Dividends may be paid when, as and if declared by the Board of Directors out
    of funds legally available therefor. Shares of Corporate Bond Series A and B
    represent  a  stockholder  interest  in a  particular  fund of  assets  and,
    accordingly,  dividends shall be calculated and declared for these series in
    the same manner,  at the same time, on the same day, and will be paid at the
    same  dividend  rate except that  expenses  attributable  to Corporate  Bond
    Series A or B and  payments  made  pursuant  to a 12b-1 Plan or  Shareholder
    Services  Plan shall be borne  exclusively  by the affected  Corporate  Bond
    Series.  Stockholders  of the Corporate Bond Series shall share in dividends
    declared  and paid  with  respect  to such  series  pro rata  based on their
    ownership of shares of such series. Shares of U.S. Government Series A and B
    represent a stockholder  interest in a particular fund of assets held by the
    corporation and, accordingly, dividends shall be calculated and declared for
    these  series in the same  manner,  at the same time,  on the same day,  and
    shall be paid at the same dividend rate,  except that expenses  attributable
    to a  particular  series  and  payments  made  pursuant  to a 12b-1  Plan or
    Shareholder  Services Plan shall be borne  exclusively  by the affected U.S.
    Government Series. Stockholders of the U.S. Government Series shall share in
    dividends  declared  and paid with  respect to such series pro rata based on
    their  ownership of shares of such series.  Whenever  dividends are declared
    and paid  with  respect  to the  Corporate  Bond  Series A and B or the U.S.
    Government  Series A and B, the holders of shares of the other  series shall
    have no rights in or to such dividends.

8.  In the event of  liquidation,  stockholders of each series shall be entitled
    to share in the assets of the corporation  that are allocated to such series
    and that are available for  distribution to the stockholders of such series.
    Liquidating  distributions  shall be made to the stockholders of each series
    pro rata based on their share ownership of such series.

9.  On the eighth  anniversary  of the purchase of shares of the Corporate  Bond
    Series B or the U.S. Government Series B (except those purchased through the
    reinvestment  of  dividends  and  other  distributions)  will  automatically
    convert  to  Corporate   Bond  Series  A  or  U.S.   Government   Series  A,
    respectively, at the relative net asset values of each of the series without
    the  imposition  of any sales  load,  fee or other  charge.  All shares in a
    stockholder's  account  that were  purchased  through  the  reinvestment  of
    dividends  and  other  distributions  will  be  considered  to be  held in a
    separate  sub-account.  Each time Series B shares are  converted to Series A
    shares,  a pro rata  portion of the Series B shares held in the  sub-account
    will also convert to Series A shares.

IN WITNESS  WHEREOF,  we have hereunto set our hands and affixed the seal of the
Corporation this 19th day of October, 1993.

corporation  at a meeting  duly  convened  and held on the 21st day of  October,
1994,  adopted  resolutions (i)  establishing  two new series of common stock in
addition  to those four series of common  stock  currently  being  issued by the
corporation,  and (ii)  allocating the  corporation's  authorized  capital stock
among the six separate  series of common stock of the  corporation.  Resolutions
were also  adopted  which for the two new series set forth and for the  existing
four series reaffirmed, the preferences,  rights, privileges and restrictions of
separate series of stock of Security Income Fund, which resolutions are provided
in their entirety as follows:

WHEREAS, the Board of Directors has approved the establishment of two new series
of common stock of Security  Income Fund in addition to the four separate series
of common  stock  presently  issued by the fund  designated  as U.S.  Government
Series A, U.S.  Government  Series B, Corporate Bond Series A and Corporate Bond

WHEREAS,  the  corporation's  shareholders  will  consider an  amendment  to the
corporation's articles of incorporation to increase the authorized capital stock
of the corporation  from 400,000,000 to  1,000,000,000  shares,  at a meeting of
shareholders to be held December 21, 1994; and

WHEREAS,  upon  approval  by  shareholders  of  the  proposed  amendment  to the
corporation's  articles  of  incorporation,  the  Board of  Directors  wishes to
reallocate  the  1,000,000,000  shares of  authorized  capital  stock  among the
series.

NOW, THEREFORE, BE IT RESOLVED, that, the officers of the corporation are hereby
directed and authorized to establish two new series of the Security  Income Fund
designated as Limited Maturity Bond Series A and Limited Maturity Bond Series B.

FURTHER RESOLVED, that, upon approval by shareholders of an amendment increasing
the  corporation's  authorized  capital stock from  400,000,000 to 1,000,000,000
shares,  the officers of the  corporation  are hereby directed and authorized to
allocate the corporation's  authorized capital stock of 1,000,000,000  shares as

1.  Except as set forth below and as may be hereafter  established  by the Board
    of Directors of the corporation all shares of the corporation, regardless of

2.  At all meetings of stockholders each stockholder of the corporation shall be
    entitled  to one vote in person or by proxy on each  matter  submitted  to a

         thereof,  such  redemption  and the valuation and payment in connection
         therewith  to  be  made  in  compliance  with  the  provisions  of  the
         Investment   Company  Act  of  1940  and  the  Rules  and   Regulations
         promulgated  thereunder  and with the  Rules  of Fair  Practice  of the
         National Association of Securities Dealers,  Inc., as from time to time
         amended.

    (b)  From and after the close of  business  on the day when the  shares  are

         Directors  determines,  be held in the treasury of the  Corporation and
         may be resold,  or, if the laws of Kansas shall permit, may be retired.
         Repurchase of shares is conditional  upon the corporation  having funds
         or property legally available therefor.

4.  All shares of the corporation,  upon issuance and sale, shall be fully paid,
    nonassessable   and  redeemable.   Within  the  respective   series  of  the
    corporation,  all shares have equal voting,  participation  and  liquidation
    rights, but have no subscription or preemptive rights.

5.  (a)  Outstanding  shares of  Corporate Bond Series A and B shall represent a
         stockholder  interest  in a  particular  fund  of  assets  held  by the
         corporation  which fund shall be invested and  reinvested in accordance
         with  policies and  objectives  established  by the Board of Directors.
         Outstanding shares of U.S.  Government Series A and B shall represent a
         stockholder  interest  in a  particular  fund  of  assets  held  by the

    (c)  All losses,  liabilities  and  expenses of the  corporation  (including
         accrued  liabilities  and  expenses  and such  reserves as the Board of
         Directors may determine are appropriate) shall be allocated and charged
         to the series to which such loss,  liability or expense relates.  Where
         any loss,  liability  or expense  relates to more than one series,  the
         Board of Directors shall allocate the same between or among such series
         pro rata based on the  respective net asset values of such series or on
         such other basis as the Board of Directors deems appropriate.

    (d)  All  allocations  made  hereunder  by the Board of  Directors  shall be
         conclusive and binding upon all stockholders and upon the corporation.

6.  Each  share of stock of a series  shall have the same  preferences,  rights,
    privileges  and  restrictions  as each other share of stock of that  series.
    Each fractional  share of stock of a series  proportionately  shall have the
    same preferences, rights, privileges and restrictions as a whole share.

7.  Dividends may be paid when, as and if declared by the Board of Directors out
    of funds legally available therefor. Shares of Corporate Bond Series A and B
    represent  a  stockholder  interest  in a  particular  fund of  assets  and,
    accordingly,  dividends shall be calculated and declared for these series in
    the same manner,  at the same time, on the same day, and will be paid at the
    same  dividend  rate except that  expenses  attributable  to Corporate  Bond
    Series A or B and  payments  made  pursuant  to a 12b-1 Plan or  Shareholder
    Services  Plan shall be borne  exclusively  by the affected  Corporate  Bond
    Series.  Stockholders  of the Corporate Bond Series shall share in dividends
    declared  and paid  with  respect  to such  series  pro rata  based on their
    ownership of shares of such series. Shares of U.S. Government Series A and B
    represent a stockholder  interest in a particular fund of assets held by the
    corporation and, accordingly, dividends shall be calculated and declared for
    these  series in the same  manner,  at the same time,  on the same day,  and
    shall be paid at the same dividend rate,  except that expenses  attributable
    to a  particular  series  and  payments  made  pursuant  to a 12b-1  Plan or
    Shareholder  Services Plan shall be borne  exclusively  by the affected U.S.
    Government Series. Stockholders of the U.S. Government Series shall share in
    dividends  declared  and paid with  respect to such series pro rata based on
    their  ownership of shares of such series.  Shares of Limited  Maturity Bond
    Series A and B represent a  stockholder  interest  in a  particular  fund of
    assets and,  accordingly,  dividends  shall be  calculated  and declared for
    these series in the same manner, at the same time, on the same day, and will
    be paid at the same  dividend  rate except  that  expenses  attributable  to
    Limited  Maturity  Bond Series A or B and payments  made pursuant to a 12b-1
    Plan or Shareholder Services Plan shall be borne exclusively by the affected
    Limited  Maturity  Bond Series.  Stockholders  of the Limited  Maturity Bond
    Series  shall  share in  dividends  declared  and paid with  respect to such
    series pro rata based on their ownership of shares of such series.  Whenever
    dividends are declared and paid with respect to the Corporate  Bond Series A
    and B, U.S. Government Series A and B, or Limited Maturity Bond Series A and
    B, the holders of shares of the other  series  shall have no rights in or to
    such dividends.

8.  In the event of  liquidation,  stockholders of each series shall be entitled
    to share in the assets of the corporation  that are allocated to such series
    and that are available for  distribution to the stockholders of such series.
    Liquidating  distributions  shall be made to the stockholders of each series
    pro rata based on their share ownership of such series.

9.  On the eighth  anniversary  of the purchase of shares of the Corporate  Bond
    Series B, U.S.  Government  Series B, or  Limited  Maturity  Bond  Series B,
    (except  those  purchased  through the  reinvestment  of dividends and other
    distributions),   such  shares  will  automatically  convert  to  shares  of
    Corporate  Bond Series A, U.S.  Government  Series A, Limited  Maturity Bond
    Series A,  respectively,  at the  relative  net asset  values of each of the
    series without the  imposition of any sales load,  fee or other charge.  All
    shares  in  a  stockholder's   account  that  were  purchased   through  the
    reinvestment  of  dividends  and other  distributions  paid with  respect to
    Series B shares  will be  considered  to be held in a separate  sub-account.
    Each time  Series B shares  are  converted  to  Series A shares,  a pro rata
    portion of the Series B shares held in the sub-account  will also convert to
    Series A shares.

We hereby certify that pursuant to said  resolution,  and in accordance with the
by-laws of the  corporation  and the laws of the State of  Kansas,  the Board of
Directors  called a meeting of stockholders  for  consideration  of the proposed
amendment to the articles of incorporation,  and thereafter,  pursuant to notice
and in  accordance  with the statutes of the State of Kansas,  the  stockholders
convened and considered the proposed  amendment.  We further certify that at the
meeting a majority  of the  stockholders  entitled to vote voted in favor of the
proposed  amendment  which was duly adopted in accordance with the provisions of
K.S.A. 17-6602, as amended.

IN WITNESS  WHEREOF,  we have hereunto set our hands and affixed the seal of the
corporation this 21st day of December, 1994.

         A and B,  to  which  they  relate  and  held  for  the  benefit  of the
         stockholders owning shares of such series.

    (c)  All losses,  liabilities  and  expenses of the  corporation  (including
         accrued  liabilities  and  expenses  and such  reserves as the Board of
         Directors may determine are appropriate) shall be allocated and charged
         to the series to which such loss,  liability or expense relates.  Where
         any loss,  liability  or expense  relates to more than one series,  the
         Board of Directors shall allocate the same between or among such series
         pro rata based on the  respective net asset values of such series or on
         such other basis as the Board of Directors deems appropriate.

    (d)  All  allocations  made  hereunder  by the Board of  Directors  shall be
         conclusive and binding upon all stockholders and upon the corporation.

6.  Each  share of stock of a series  shall have the same  preferences,  rights,
    privileges  and  restrictions  as each other share of stock of that  series.
    Each fractional  share of stock of a series  proportionately  shall have the
    same preferences, rights, privileges and restrictions as a whole share.

7.  Dividends may be paid when, as and if declared by the Board of Directors out
    of funds legally available therefor. Shares of Corporate Bond Series A and B
    represent  a  stockholder  interest  in a  particular  fund of  assets  and,
    accordingly,  dividends shall be calculated and declared for these series in
    the same manner,  at the same time, on the same day, and will be paid at the
    same  dividend  rate except that  expenses  attributable  to Corporate  Bond
    Series A or B and  payments  made  pursuant  to a 12b-1 Plan or  Shareholder
    Services  Plan shall be borne  exclusively  by the affected  Corporate  Bond
    Series.  Stockholders  of the Corporate Bond Series shall share in dividends
    declared  and paid  with  respect  to such  series  pro rata  based on their
    ownership of shares of such series. Shares of U.S. Government Series A and B
    represent a stockholder  interest in a particular fund of assets held by the
    corporation and, accordingly, dividends shall be calculated and declared for
    these  series in the same  manner,  at the same time,  on the same day,  and
    shall be paid at the same dividend rate,  except that expenses  attributable
    to a  particular  series  and  payments  made  pursuant  to a 12b-1  Plan or
    Shareholder  Services Plan shall be borne  exclusively  by the affected U.S.
    Government Series. Stockholders of the U.S. Government Series shall share in
    dividends  declared  and paid with  respect to such series pro rata based on
    their  ownership of shares of such series.  Shares of Limited  Maturity Bond
    Series A and B represent a  stockholder  interest  in a  particular  fund of
    assets and,  accordingly,  dividends  shall be  calculated  and declared for
    these series in the same manner, at the same time, on the same day, and will
    be paid at the same  dividend  rate except  that  expenses  attributable  to
    Limited  Maturity  Bond Series A or B and payments  made pursuant to a 12b-1
    Plan or Shareholder Services Plan shall be borne exclusively by the affected
    Limited  Maturity  Bond Series.  Stockholders  of the Limited  Maturity Bond
    Series  shall  share in  dividends  declared  and paid with  respect to such
    series pro rata based on their ownership of shares of such series. Shares of
    Global Aggressive Bond Series A and B represent a stockholder  interest in a
    particular fund of assets and accordingly, dividends shall be calculated and
    declared for these series in the same manner,  at the same time, on the same
    day,  and  will be paid at the  same  dividend  rate  except  that  expenses
    attributable  to Global  Aggressive  Bond  Series A or B and  payments  made
    pursuant  to a  12b-1  Plan  or  Shareholder  Services  Plan  shall  be born
    exclusively by the affected Global  Aggressive Bond Series.  Stockholders of
    the Global Aggressive Bond Series A and B shall share in dividends  declared
    and paid with  respect to such series pro rata based on their  ownership  of
    shares of such series. Whenever dividends are declared and paid with respect
    to the  Corporate  Bond  Series  A and B,  U.S.  Government  Series A and B,
    Limited Maturity Bond Series A and B, or Global Aggressive Bond Series A and
    B, the holders of shares of the other  series  shall have no rights in or to
    such dividends.

8.  In the event of  liquidation,  stockholders of each series shall be entitled
    to share in the assets of the corporation  that are allocated to such series
    and that are available for  distribution to the stockholders of such series.
    Liquidating  distributions  shall be made to the stockholders of each series
    pro rata based on their share ownership of such series.

9.  On the eighth  anniversary  of the purchase of shares of the Corporate  Bond
    Series B, U.S.  Government  Series B,  Limited  Maturity  Bond  Series B, or
    Global  Aggressive  Bond  Series B,  (except  those  purchased  through  the
    reinvestment  of  dividends  and  other  distributions),  such  shares  will
    automatically  convert to shares of Corporate Bond Series A, U.S. Government
    Series A, Limited Maturity Bond Series A, or Global Aggressive Bond Series A
    respectively, at the relative net asset values of each of the series without
    the  imposition  of any sales  load,  fee or other  charge.  All shares in a
    stockholder's  account  that were  purchased  through  the  reinvestment  of
    dividends and other  distributions paid with respect to Series B shares will
    be  considered  to be held in a  separate  sub-account.  Each time  Series B
    shares are converted to Series A shares,  a pro rata portion of the Series B
    shares held in the sub-account will also convert to Series A shares.

corporation this 3rd day of February, 1995.

COUNTY OF SHAWNEE)

We, John D. Cleland,  President,  and Amy J. Lee,  Secretary of Security  Income
Fund,  a  corporation  organized  and  existing  under  the laws of the State of
Kansas,  and whose  registered  office is Security  Benefit Life  Building,  700
Harrison Street, Topeka, Shawnee County, Kansas, do hereby certify that pursuant
to authority expressly vested in the Board of Directors by the provisions of the
corporation's  Articles  of  Incorporation,  the  Board  of  Directors  of  said
corporation  at a meeting duly  convened  and held on the 3rd day of May,  1996,
adopted  resolutions (i) establishing two new series of common stock in addition
to those eight series of common stock currently being issued by the corporation,
and (ii)  allocating the  corporation's  authorized  capital stock among the ten
separate  series  of  common  stock of the  corporation.  Resolutions  were also
adopted  which  for the two new  series  set forth  and for the  existing  eight
reaffirmed the  preferences,  rights,  privileges and  restrictions  of separate
series of stock of Security Income Fund, which resolutions are provided in their
entirety as follows:

WHEREAS, the Board of Directors has approved the establishment of two new series
of common stock of Security Income Fund in addition to the eight separate series
of common stock presently issued by the fund designated as Corporate Bond Series

Aggressive Bond Series A and Global Aggressive Bond Series B; and

WHEREAS,  the  Board of  Directors  desires  to  authorize  the  issuance  of an
indefinite number of shares of capital stock of each of the ten series of common
stock of the corporation.

NOW, THEREFORE, BE IT RESOLVED, that, the officers of the corporation are hereby
directed and authorized to establish two new series of the Security  Income Fund
designated as High Yield Series A and High Yield Series B.

FURTHER RESOLVED,  that, the officers of the corporation are hereby directed and

stock of each series of the corporation,  which consist of Corporate Bond Series

Limited  Maturity  Bond  Series  A,  Limited  Maturity  Bond  Series  B,  Global
Aggressive  Bond Series A, Global  Aggressive Bond Series B, High Yield Series A

FURTHER RESOLVED, that the preferences,  rights,  privileges and restrictions of
the shares of each series of Security Income Fund shall be as follows:

1.  Except as set forth below and as may be hereafter  established  by the Board
    of Directors of the corporation all shares of the corporation, regardless of
    series, shall be equal.

2.  At all meetings of stockholders each stockholder of the corporation shall be
    entitled  to one vote in person or by proxy on each  matter  submitted  to a
    vote at such meeting for each share of common  stock  standing in his or her
    name on the books of the  corporation on the date,  fixed in accordance with
    the  bylaws,  for  determination  of  stockholders  entitled to vote at such
    meeting. At all elections of directors each stockholder shall be entitled to
    as many votes as shall equal the number of shares of stock multiplied by the
    number of directors to be elected,  and he or she may cast all of such votes
    for a single  director or may  distribute  them among the number to be voted
    for,  or any two or more of them as he or she may see  fit.  Notwithstanding
    the foregoing, (i) if any matter is submitted to the stockholders which does
    not  affect the  interests  of all  series,  then only  stockholders  of the
    affected  series  shall  be  entitled  to vote  and  (ii) in the  event  the
    Investment  Company Act of 1940,  as amended,  or the rules and  regulations
    promulgated  thereunder shall require a greater or different vote than would
    otherwise  be required  herein or by the  Articles of  Incorporation  of the
    corporation,  such greater or  different  voting  requirement  shall also be
    satisfied.

3.  (a)  The  corporation  shall  redeem  any of its  shares  for  which  it has
         received  payment in full that may be presented to the  corporation  on
         any date after the issue date of any such shares at the net asset value
         thereof,  such  redemption  and the valuation and payment in connection
         therewith  to  be  made  in  compliance  with  the  provisions  of  the
         Investment   Company  Act  of  1940  and  the  Rules  and   Regulations
         promulgated  thereunder  and with the  Rules  of Fair  Practice  of the
         National Association of Securities Dealers,  Inc., as from time to time
         amended.

    (b)  From and after the close of  business  on the day when the  shares  are
         properly  tendered for repurchase the owner shall, with respect of said
         shares,  cease to be a stockholder  of the  corporation  and shall have
         only the right to receive the repurchase  price in accordance  with the
         provisions  hereof.  The  shares so  repurchased  may,  as the Board of
         Directors  determines,  be held in the treasury of the  Corporation and
         may be resold,  or, if the laws of Kansas shall permit, may be retired.
         Repurchase of shares is conditional  upon the corporation  having funds
         or property legally available therefor.

4.  All shares of the corporation,  upon issuance and sale, shall be fully paid,
    nonassessable   and  redeemable.   Within  the  respective   series  of  the
    corporation,  all shares have equal voting,  participation  and  liquidation
    rights, but have no subscription or preemptive rights.

         stockholder  interest  in a  particular  fund  of  assets  held  by the
         corporation  which fund shall be invested and  reinvested in accordance
         with  policies and  objectives  established  by the Board of Directors.

         of shares of Corporate Bond Series A and B, the U.S.  Government Series
         A and B, Limited  Maturity Bond Series A and B, Global  Aggressive Bond

         Directors may determine are appropriate) shall be allocated and charged
         to the series to which such loss,  liability or expense relates.  Where
         any loss,  liability  or expense  relates to more than one series,  the
         Board of Directors shall allocate the same between or among such series
         pro rata based on the  respective net asset values of such series or on
         such other basis as the Board of Directors deems appropriate.

    (d)  All  allocations  made  hereunder  by the Board of  Directors  shall be

7.  Dividends may be paid when, as and if declared by the Board of Directors out
    of funds legally available therefor. Shares of Corporate Bond Series A and B
    represent  a  stockholder  interest  in a  particular  fund of  assets  and,
    accordingly,  dividends shall be calculated and declared for these series in
    the same manner,  at the same time, on the same day, and will be paid at the
    same  dividend  rate except that  expenses  attributable  to Corporate  Bond
    Series A or B and  payments  made  pursuant  to a 12b-1 Plan or  Shareholder
    Services  Plan shall be borne  exclusively  by the affected  Corporate  Bond
    Series.  Stockholders  of the Corporate Bond Series shall share in dividends

    shall be paid at the same dividend rate,  except that expenses  attributable
    to a  particular  series  and  payments  made  pursuant  to a 12b-1  Plan or

    be paid at the same  dividend  rate except  that  expenses  attributable  to
    Limited  Maturity  Bond Series A or B and payments  made pursuant to a 12b-1
    Plan or Shareholder Services Plan shall be borne exclusively by the affected
    Limited  Maturity  Bond Series.  Stockholders  of the Limited  Maturity Bond
    Series  shall  share in  dividends  declared  and paid with  respect to such
    series pro rata based on their ownership of shares of such series. Shares of
    Global Aggressive Bond Series A and B represent a stockholder  interest in a
    particular fund of assets and accordingly, dividends shall be calculated and
    declared for these series in the same manner,  at the same time, on the same
    day,  and  will be paid at the  same  dividend  rate  except  that  expenses
    attributable  to Global  Aggressive  Bond  Series A or B and  payments  made
    pursuant  to a  12b-1  Plan  or  Shareholder  Services  Plan  shall  be born
    exclusively by the affected Global  Aggressive Bond Series.  Stockholders of
    the Global Aggressive Bond Series A and B shall share in dividends  declared
    and paid with  respect to such series pro rata based on their  ownership  of
    shares of such  series.  Shares of High  Yield  Series A and B  represent  a
    stockholder  interest  in a  particular  fund of  assets  and,  accordingly,
    dividends  shall be  calculated  and  declared  for these series in the same
    manner,  at the same  time,  on the same  day,  and will be paid at the same
    dividend rate except that expenses  attributable to High Yield Series A or B
    and payments  made  pursuant to a 12b-1 Plan or  Shareholder  Services  Plan
    shall be borne  exclusively by the affected High Yield Series.  Stockholders
    of the High Yield  Series  shall share in  dividends  declared and paid with
    respect to such series pro rata based on their  ownership  of shares of such
    series.  Whenever  dividends  are  declared  and paid  with  respect  to the
    Corporate  Bond  Series A and B,  U.S.  Government  Series A and B,  Limited
    Maturity Bond Series A and B, Global Aggressive Bond Series A and B, or High
    Yield  Series A and B, the holders of shares of the other  series shall have
    no rights in or to such dividends.

8.  In the event of  liquidation,  stockholders of each series shall be entitled
    to share in the assets of the corporation  that are allocated to such series
    and that are available for  distribution to the stockholders of such series.
    Liquidating  distributions  shall be made to the stockholders of each series
    pro rata based on their share ownership of such series.

9.  On the eighth  anniversary  of the purchase of shares of the Corporate  Bond
    Series B, U.S.  Government  Series B, Limited Maturity Bond Series B, Global
    Aggressive  Bond Series B, or High Yield Series B, (except  those  purchased
    through the reinvestment of dividends and other distributions),  such shares
    will  automatically  convert  to shares  of  Corporate  Bond  Series A, U.S.
    Government  Series A, Limited Maturity Bond Series A, Global Aggressive Bond
    Series A, or High Yield  Series A,  respectively,  at the relative net asset
    values of each of the series  without the  imposition of any sales load, fee
    or other charge.  All shares in a stockholder's  account that were purchased
    through the  reinvestment  of dividends  and other  distributions  paid with
    respect  to  Series B shares  will be  considered  to be held in a  separate
    sub-account.  Each time Series B shares are converted to Series A shares,  a
    pro rata  portion of the Series B shares held in the  sub-account  will also
    convert to Series A shares.

FURTHER RESOLVED, that, the appropriate officers of the corporation be, and they
hereby are,  authorized  and  directed  to take such action as may be  necessary
under the laws of the State of Kansas or as they deem  appropriate  to cause the
foregoing resolutions to become effective.

corporation this 13th day of May, 1996.

corporation  at a meeting  duly  convened  and held on the 7th day of  February,
1997,  adopted  resolutions (i) establishing  four new series of common stock in
addition  to those ten  series of common  stock  currently  being  issued by the
corporation,  and (ii)  allocating the  corporation's  authorized  capital stock
among  the  fourteen  separate  series  of  common  stock  of  the  corporation.
Resolutions  were also adopted,  which for the four new series set forth and for
the existing ten reaffirmed the preferences, rights, privileges and restrictions
of separate  series of stock of Security  Income  Fund,  which  resolutions  are
provided in their entirety as follows:

Return Series B, Global Asset  Allocation  Series A and Global Asset  Allocation

     of series, shall be equal.

2.   At all meetings of stockholders  each stockholder of the corporation  shall
     be entitled to one vote in person or by proxy on each matter submitted to a
     vote at such meeting for each share of common stock  standing in his or her
     name on the books of the corporation on the date,  fixed in accordance with

     Incorporation  of  the  corporation,   such  greater  or  different  voting
     requirement shall also be satisfied.

3.   (a)  The  corporation  shall  redeem  any of its  shares  for  which it has

          Repurchase of shares is conditional upon the corporation  having funds
          or property legally available therefor.

    of Directors of the corporation all shares of the corporation, regardless of
    series, shall be equal.

2.  At all meetings of stockholders each stockholder of the corporation shall be
    entitled  to one vote in person or by proxy on each  matter  submitted  to a

    the  bylaws,  for  determination  of  stockholders  entitled to vote at such
    meeting. At all elections of directors each stockholder shall be entitled to
    as many votes as shall equal the number of shares of stock multiplied by the
    number of directors to be elected,  and he or she may cast all of such votes
    for a single  director or may  distribute  them among the number to be voted

    Investment  Company Act of 1940,  as amended,  or the rules and  regulations
    promulgated  thereunder shall require a greater or different vote than would
    otherwise  be required  herein or by the  Articles of  Incorporation  of the
    corporation,  such greater or  different  voting  requirement  shall also be

         thereof,  such  redemption  and the valuation and payment in connection
         therewith  to  be  made  in  compliance  with  the  provisions  of  the
         Investment   Company  Act  of  1940  and  the  Rules  and   Regulations
         promulgated  thereunder  and with  the  Conduct  Rules of the  National

         or property legally available therefor.

                             DISTRIBUTION AGREEMENT


THIS AGREEMENT,  made this 14th day of September,  1970,  between  SECURITY BOND
FUND, INC., a Kansas corporation (hereinafter referred to as the "Company"), and
SECURITY  DISTRIBUTORS,  INC., a Kansas corporation  (hereinafter referred to as
the "Distributor").

                                   WITNESSETH:

WHEREAS,  the  Company  is  engaged  in  business  as  an  open-end,  management
investment  company registered under the federal Investment Company Act of 1940;
and

WHEREAS,  the  Distributor  is willing to act as principal  underwriter  for the
Company to offer for sale,  sell and deliver  after sale shares of the Company's
$1 par value common stock (hereinafter referred to as the "Shares") on the terms
and conditions hereinafter set forth;

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

 1.  EMPLOYMENT OF  DISTRIBUTOR.  The Company hereby employs the  Distributor to
     act as principal  underwriter for the Company and hereby agrees that during
     the term of this Agreement,  and any renewal or extension thereof, or until
     any prior  termination  thereof,  the Distributor  shall have the exclusive
     right to offer for sale and to  distribute  any and all Shares issued or to
     be issued by the Company.  The  Distributor  hereby accepts such employment
     and agrees to act as the  distributor  of the Shares issued or to be issues
     by the  Company  during the period this  Agreement  is in effect and agrees
     during  such  period to offer for sale such  Shares as long as such  Shares
     remain available for sale, unless the Distributor is unable legally to make
     such offer for sale as the result of any law or governmental regulation.

 2.  OFFERING PRICE AND COMMISSIONS.  Prior to the issuance of any Shares by the
     Company pursuant to any subscription tendered by or through the Distributor
     and confirmed for sale to or through the Distributor, the Distributor shall
     pay or cause to be paid to the  Custodian of the Company in cash, an amount
     equal to the net asset  value of such Shares at the time of  acceptance  of
     each such  subscription and confirmation by the Company of the sale of such
     Shares.  The  Distributor  shall be entitled to charge a commission on each
     such sale of Shares in the  amount set forth in the  Company's  Prospectus,
     such  commission  to be an amount equal to the  difference  between the net
     asset value and the offering  price of the Shares,  as such offering  price
     may  from  time to time be  determined  by the  board of  directors  of the
     Company.  All  Shares  shall be sold to the  public  only at  their  public
     offering  price at the time of such sale, and the Company shall receive not
     less than the full net asset value thereof.

 3.  ALLOCATION OF EXPENSES AND CHARGES.  During the period this Agreement is in
     effect, the Company shall pay all costs and expenses in connection with the
     registration  of Shares under the  Securities  Act of 1933,  including  all
     expenses  in  connection   with  the   preparation   and  printing  of  any
     registration   statements  and  prospectuses   necessary  for  registration
     thereunder  but excluding  any  additional  costs and expenses  incurred in
     furnishing the Distributor with prospectuses.

     During the period this Agreement is in effect the  Distributor  will pay or
     reimburse the Company for:

     (a)  All  costs,   expenses  and  fees  incurred  in  connection  with  the
          qualification  of the Shares under the applicable Blue Sky laws of the
          states in which the Shares are offered;

     (b)  All costs and  expenses of printing  and mailing  prospectuses  (other
          than to existing  shareholders) and  confirmations,  and all costs and
          expenses of preparing, printing and mailing advertising material sales
          literature, circulars, applications, and other materials used or to be
          used in connection  with the offering for sale and the sale of Shares;
          and

     (c)  All clerical and  administrative  costs in processing the applications
          for and in connection with the sale of Shares.

          The Distributor agrees to submit to the Company for its prior approval
          all advertising  material,  sales literature,  circulars and any other
          material which the Distributor  proposes to use in connection with the
          offering for sale of Shares.

 4.  DISTRIBUTOR MAY ACT AS BROKER AND RECEIVE COMMISSIONS.  Notwithstanding any
     other  provisions of this  Agreement,  it is understood and agreed that the
     Distributor may act as a broker, on behalf of the Company,  in the purchase
     and sale of securities not effected on a securities exchange, provided that
     any such transactions and any commission paid in connection therewith shall
     comply in every  respect with the  requirements  of the Federal  Investment
     Company Act of 1940 and in  particular  with Section  17(c) of said statute
     and the Rules and  Regulations of the  Securities  and Exchange  Commission
     promulgated thereunder.

 5.  AGREEMENT  SUBJECT TO APPLICABLE  LAW AND  REGULATIONS.  The parties hereto
     agree that all  provisions  of this  Agreement  will be performed in strict
     accordance with the requirements of the Investment Company Act of 1940, the
     Securities Act of 1933, the Securities  Exchange Act of 1934, and the rules
     and  regulations  of the  Securities  and  exchange  Commission  under said
     statutes,  in strict  accordance with all applicable  state "Blue Sky" laws
     and the rules and regulations thereunder, and in strict accordance with the
     provisions of the Articles of Incorporation and Bylaws of the Company.

 6.  DURATION  AND  TERMINATION  OF  AGREEMENT.   This  Agreement  shall  become
     effective at the date and time that the  Company's  prospectus,  reflecting
     the  underwriting  arrangements  provided by this  Agreement,  shall become
     effective  under the  Securities  Act of 1933,  and shall continue in force
     until December 31, 1971, and from year to year thereafter, but only if such
     continuance  is  specifically  approved  at least  annually by the board of
     directors of the Company and the majority of the board of directors who are
     not parties to this Agreement or affiliated  persons of any such party,  or
     by the vote of a  majority  of the  outstanding  voting  securities  of the
     Company.  Written  notice of any such approval by the board of directors or
     by the holders of a majority of the  outstanding  voting  securities of the
     Company shall be given promptly to the Distributor.

     This  Agreement  may be terminated by the Company at any time by giving the
     Distributor  at least  sixty  (60)  days  previous  written  notice of such
     intention to terminate. This Agreement may be terminated by the Distributor
     at any time by giving the Company at least sixty (60) days previous written
     notice of such intention to terminate.

     This Agreement shall terminate automatically in the event of its assignment
     by  the  Distributor.   As  used  in  the  preceding  sentence,   the  word
     "assignment"  shall have the  meaning  set forth in Section  2(a)(4) of the
     Investment Company Act of 1940.

 7.  CONSTRUCTION OF AGREEMENT. No provision of this Agreement is intended to or
     shall be construed as protecting the  Distributor  against any liability to
     the Company or to the Company's  security  holders to which the Distributor
     would otherwise be subject by reason of willful  misfeasance,  bad faith or
     gross  negligence  in the  performance  of its  duties  or by reason of the
     Distributor's  reckless  disregard of its obligations and duties under this
     Agreement.

     Terms or words used in this Agreement,  which also occur in the Articles of
     Incorporation or Bylaws of the Company,  shall have the same meaning herein
     as given to such terms or words in Articles of  Incorporation  or Bylaws of
     the Company.

 8.  DISTRIBUTOR AN INDEPENDENT CONTRIBUTOR.  The Distributor shall be deemed to
     be  an  independent   contractor  and,  except  as  expressly  provided  or
     authorized by the Company,  shall have no authority to act for or represent
     the Company.

 9.  NOTICE. Any notice required or permitted to be given hereunder to either of
     the  parties  hereto  shall be  deemed  to have  been  given if  mailed  by
     certified mail in a postage  prepaid  envelope  addressed to the respective
     party as follows, unless any such party has notified the other party hereto

                       AMENDMENT TO DISTRIBUTION AGREEMENT


WHEREAS, Security Income Fund (the "Company"),  formerly Security Bond Fund, and
Security  Distributors,  Inc. (the  "Distributor") are parties to a Distribution
Agreement dated as of September 14, 1970, (the  "Distribution  Agreement") under
which the Distributor agrees to act as principal  underwriter in connection with
the sales of shares of the Company's capital stock; and

WHEREAS,  a Distribution Plan (the "Plan") has been adopted by the directors and
shareholders of Security Income Fund pursuant to Rule 12b-1 under the Investment
Company Act of 1940 (the "Act"), the provisions of which have an effect upon the
relationship  between  the  Company and the  Distributor,  and the  Distribution
Agreement; and

WHEREAS, the Company and Distributor wish to amend the Distribution Agreement to
conform to the  requirements  of Rule 12b-1 under the Act and to incorporate the
necessary provisions into the Agreement.

NOW  THEREFORE,  the  Company  and  Distributor  hereby  amend the  Distribution
Agreement, effective immediately, as follows:

1.  New Section 4A is added to the Agreement, which provides as follows:

    4A.  DISTRIBUTION PLAN.

    (a)  Pursuant to a Distribution Plan adopted by the Fund, the Fund agrees to
         make monthly  payments to the  Distributor in an amount  computed at an
         annual rate of .25 of 1% of the Fund's  average  daily net  assets,  to
         finance  activities  undertaken by the  Distributor  for the purpose of
         distributing  the  Fund's  shares  to  investors.  The  Distributor  is
         obligated to and hereby  agrees to use the entire amount of said fee to
         finance the following distribution-related activities:

           (i)  Preparation,  printing and  distribution  of the  Prospectus and
                Statement of Additional  Information and any supplement  thereto
                used in connection with the offering of shares to the public;

          (ii)  Printing  of  additional  copies for use by the  Distributor  as
                sales literature, of reports and other communications which were
                prepared by the Fund for distribution to existing shareholders;

         (iii)  Preparation,  printing  and  distribution  of  any  other  sales
                literature used in connection with the offering of shares to the
                public;

          (iv)  Expenses  incurred in advertising,  promoting and selling shares
                of the Fund to the public; and

           (v)  Any  fees  paid by the  Distributor  to  securities  dealers  as
                distribution  or  service  fees who  have  executed  a  Dealer's
                Distribution Agreement with the Distributor.

    (b)  All payments to the Distributor  pursuant to this paragraph are subject
         to the following conditions being met by the Distributor:

           (i)  For the fiscal year of the Fund during  which this Plan  becomes
                effective and for each subsequent fiscal year of the Fund during
                which this Plan remains in effect,  the Distributor shall submit
                to the Fund a budget  setting  forth in  reasonable  detail  the
                distribution-related   activities   to  which  the   Distributor
                proposes to apply payments made by the Fund hereunder;

          (ii)  Before any payment is made to the  Distributor in respect of any
                fiscal year,  the budget  relating  thereto shall be approved by
                vote of the Fund's Directors,  including the affirmative vote of
                a majority of the Independent Directors.

         (iii)  The Distributor shall furnish the Fund with quarterly reports of
                its expenditures  pursuant to each budget so approved,  together
                with  receipts  or other  appropriate  written  evidence  of the
                amounts expended,  and such other  information  relating to such
                budget  or  expenditures  or to the  other  distribution-related
                activities  undertaken  or  proposed  to be  undertaken  by  the
                Distributor  during  such  fiscal  year  under its  Distribution
                Agreement with the Fund as the Fund may reasonably request;

    (c)  The Dealer's Distribution  Agreement (the "Agreement")  contemplated by
         paragraph 2(v) above shall permit payments to securities dealers by the
         Distributor  only in accordance  with the  provisions of this paragraph
         and shall have the  approval of the  majority of the Board of Directors
         of  the  Fund  including  a  majority  of the  directors  who  are  not
         interested persons of the Fund as required by the Rule. The Distributor
         may  pay to the  other  party  to any  Agreement  a  quarterly  fee for
         distribution and marketing  services provided by such other party. Such
         quarterly  fee shall be payable  in arrears in an amount  equal to such
         percentage  (not in excess of .000685%  per day) of the  aggregate  net
         asset  value of the shares  held by such  other  party's  customers  or
         clients at the close of business  each day as  determined  from time to
         time  by the  Distributor.  The  distribution  and  marketing  services
         contemplated  hereby shall include,  but are not limited to,  answering
         inquiries  regarding  the Fund,  account  designations  and  addresses,
         maintaining  the investment of such other party's  customers or clients
         in the Fund and similar  services.  In  determining  the extent of such
         other  party's   assistance  in  maintaining  such  investment  by  its
         customers  or  clients,  the  Distributor  may take  into  account  the
         possibility  that the shares held by such  customer or client  would be
         redeemed in the absence of such quarterly fee.

    (d)  The provisions of the Distribution Plan approved by the Shareholders of
         the Fund on July 12, 1985, and by the Board of Directors of the Fund on

THIS AGREEMENT, made this 1st day of October 1993, between Security Income Fund,
a Kansas corporation  (hereinafter  referred to as the "Company"),  and Security
Distributors,  Inc.,  a  Kansas  corporation  (hereinafter  referred  to as  the
"Distributor").

                                   WITNESSETH:

WHEREAS,  the  Company  is  engaged  in  business  as  an  open-end,  management
investment  company  registered under the federal Investment Company Act of 1940
(the "1940 Act"); and

WHEREAS,  the  Distributor  is willing to act as principal  underwriter  for the
Company to offer for sale,  sell and deliver  after sale,  the Class B Shares of
the  Company's  $1.00 par value  common  stock  (hereinafter  referred to as the
"Shares") on the terms and conditions hereinafter set forth;

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

 1.  EMPLOYMENT OF  DISTRIBUTOR.  The Company hereby employs the  Distributor to
     act as  principal  underwriter  for the Company with respect to its Class B
     Shares and hereby  agrees that during the term of this  Agreement,  and any
     renewal or extension thereof, or until any prior termination  thereof,  the
     Distributor  shall  have  the  exclusive  right  to  offer  for sale and to
     distribute  any and all of its Class B Shares issued or to be issued by the
     Company.  The Distributor  hereby accepts such employment and agrees to act
     as the  distributor  of the  Class B Shares  issued  or to be issued by the
     Company  during the period this  Agreement  is in effect and agrees  during
     such  period to offer for sale such  Shares as long as such  Shares  remain
     available for sale,  unless the  Distributor is unable legally to make such
     offer for sale as the result of any law or governmental regulation.

 2.  OFFERING PRICE AND COMMISSIONS.  Prior to the issuance of any Shares by the
     Company pursuant to any subscription tendered by or through the Distributor
     and confirmed for sale to or through the Distributor, the Distributor shall
     pay or cause to be paid to the  custodian of the Company in cash, an amount
     equal to the net asset  value of such Shares at the time of  acceptance  of
     each such  subscription and confirmation by the Company of the sale of such
     Shares.  All  Shares  shall  be sold to the  public  only at  their  public
     offering  price at the time of such sale, and the Company shall receive not
     less than the full net asset value thereof.

 3.  ALLOCATION OF EXPENSES AND CHARGES.  During the period this Agreement is in
     effect, the Company shall pay all costs and expenses in connection with the
     registration  of Shares under the  Securities Act of 1933 (the "1933 Act"),
     including all expenses in connection  with the  preparation and printing of
     any  registration  statements and  prospectuses  necessary for registration
     thereunder  but excluding  any  additional  costs and expenses  incurred in
     furnishing the Distributor with prospectuses.

The Company will also pay all costs,  expenses and fees  incurred in  connection
with the  qualification  of the Shares under the applicable Blue Sky laws of the
states in which the Shares are offered.

During the period  this  Agreement  is in effect,  the  Distributor  will pay or
reimburse the Company for:

     (a)  All costs and  expenses of printing  and mailing  prospectuses  (other
          than to existing  shareholders) and  confirmations,  and all costs and
          expenses of  preparing,  printing  and mailing  advertising  material,
          sales literature, circulars, applications, and other materials used or
          to be used in  connection  with the  offering for sale and the sale of
          Shares; and

     (b)  All clerical and  administrative  costs in processing the applications
          for and in connection with the sale of Shares.

The  Distributor  agrees to submit to the  Company  for its prior  approval  all
advertising material,  sales literature,  circulars and any other material which
the  Distributor  proposes to use in  connection  with the  offering for sale of
Shares.

 4.  REDEMPTION OF SHARES.  The Distributor,  as agent of and for the account of
     the Fund, may redeem Shares of the Fund offered for resale to it at the net
     asset value of such  Shares  (determined  as  provided  in the  Articles of
     Incorporation  or Bylaws) and not in excess of such maximum  amounts as may
     be fixed from time to time by an officer of the Fund. Whenever the officers
     of the Fund deem it advisable for the protection of the shareholders of the
     Fund, they may suspend or cancel such authority.

 5.  SALES CHARGES. A contingent  deferred sales charge shall be retained by the
     Distributor  from the net  asset  value of  Shares  of the Fund that it has
     redeemed,  it being  understood  that such amounts will not be in excess of
     that set  forth in the  then-current  registration  statement  of the Fund.
     Furthermore,  the Distributor may retain any amounts authorized for payment
     to it under the Fund's Distribution Plan.

 6.  DISTRIBUTOR MAY ACT AS BROKER AND RECEIVE COMMISSIONS.  Notwithstanding any
     other  provisions of this  Agreement,  it is understood and agreed that the
     Distributor may act as a broker, on behalf of the Company,  in the purchase
     and sale of securities not effected on a securities exchange, provided that
     any such transactions and any commission paid in connection therewith shall

THIS AGREEMENT,  made this ___ day of ________,  1999,  between  Security Income
Fund,  a Kansas  corporation  (hereinafter  referred to as the  "Company"),  and
Security  Distributors,  Inc., a Kansas corporation  (hereinafter referred to as
the "Distributor").

                                   WITNESSETH:

WHEREAS,  the  Company  is  engaged  in  business  as  an  open-end,  management
investment  company  registered under the federal Investment Company Act of 1940
(the "1940 Act");

WHEREAS, the Company issues its stock in several series; and

WHEREAS,  the  Distributor  is willing to act as principal  underwriter  for the
Company to offer for sale,  sell and deliver after sale,  the Class C  Shares of
the Company's Capital Preservation Series of common stock (hereinafter  referred
to as the "Shares") on the terms and conditions hereinafter set forth;

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

   1.   Employment of Distributor. The Company hereby employs the Distributor to
        act as principal underwriter for the Company with respect to its Class C
        Shares and hereby agrees that during the term of this Agreement, and any
        renewal or extension  thereof,  or until any prior termination  thereof,
        the Distributor  shall have the exclusive right to offer for sale and to
        distribute  any and all of the Class C  Shares issued or to be issued by
        the Company.  The Distributor  hereby accepts such employment and agrees
        to act as the  distributor  of the Class C Shares issued or to be issued
        by the Company  during the period this Agreement is in effect and agrees
        during  such period to offer for sale such Shares as long as such Shares
        remain  available for sale,  unless the Distributor is unable legally to
        make  such  offer  for  sale as the  result  of any law or  governmental
        regulation.

   2.   Offering Price and  Commissions.  Prior to the issuance of any Shares by
        the  Company  pursuant  to any  subscription  tendered by or through the
        Distributor  and confirmed for sale to or through the  Distributor,  the
        Distributor  shall  pay or  cause  to be  paid to the  custodian  of the
        Company in cash,  an amount  equal to the net asset value of such Shares
        at the time of acceptance of each such  subscription and confirmation by
        the Company of the sale of such Shares.  All Shares shall be sold to the
        public only at their public offering price at the time of such sale, and
        the  Company  shall  receive  not less  than the  full net  asset  value
        thereof.

   3.   Allocation of Expenses and Charges.  During the period this Agreement is
        in effect,  the Company  shall pay all costs and expenses in  connection
        with the  registration  of Shares under the  Securities Act of 1933 (the
        "1933 Act"),  including all expenses in connection  with the preparation
        and printing of any registration  statements and prospectuses  necessary
        for  registration  thereunder  but  excluding any  additional  costs and
        expenses incurred in furnishing the Distributor with prospectuses.

        The  Company  also will pay all costs,  expenses  and fees  incurred  in
        connection  with the  qualification  of the Shares under the  applicable
        Blue Sky laws of the states in which the Shares are offered.

        During the period this Agreement is in effect,  the Distributor will pay
        or reimburse the Company for:

        (a)  All costs and expenses of printing and mailing  prospectuses (other
             than to existing shareholders) and confirmations, and all costs and
             expenses of preparing,  printing and mailing advertising  material,
             sales literature, circulars, applications, and other materials used
             or to be used in connection with the offering for sale and the sale
             of Shares; and

        (b)  All   clerical  and   administrative   costs  in   processing   the
             applications for and in connection with the sale of Shares.

        The  Distributor  agrees to submit to the Company for its prior approval
        all  advertising  material,  sales  literature,  circulars and any other
        material which the  Distributor  proposes to use in connection  with the
        offering for sale of Shares.

   4.   Redemption of Shares.  The Distributor,  as agent of and for the account
        of the Fund,  may redeem  Shares of the Fund offered for resale to it at
        the net  asset  value of such  Shares  (determined  as  provided  in the
        then-current  registration  statement  of the Fund) and not in excess of
        such maximum  amounts as may be fixed from time to time by an officer of
        the Fund.  Whenever the  officers of the Fund deem it advisable  for the
        protection of the  shareholders  of the Fund, they may suspend or cancel
        such authority.

   5.   Sales Charges.  A contingent  deferred sales charge shall be retained by
        the  Distributor  from the net asset value of Shares of the Fund that it
        has  redeemed,  it being  understood  that such  amounts  will not be in
        excess of that set forth in the then-current  registration  statement of
        the Fund. Furthermore, the Distributor may retain any amounts authorized
        for payment to it under the Fund's Distribution Plan.

   6.   Distributor May Act as Broker and Receive  Commissions.  Notwithstanding
        any other provisions of this Agreement, it is understood and agreed that
        the  Distributor may act as a broker,  on behalf of the Company,  in the
        purchase and sale of securities  not effected on a securities  exchange,
        provided  that  any  such   transactions  and  any  commission  paid  in
        connection therewith shall comply in every respect with the requirements
        of the 1940 Act and in particular with Section 17(e) of that Act and the
        rules  and  regulations  of  the  Securities  and  Exchange   Commission
        promulgated thereunder.

   7.   Agreements Subject to Applicable Law and Regulations. The parties hereto
        agree that all  provisions of this Agreement will be performed in strict

4.1   THE COMPANY

The Company covenants that:

           in all such Fund  documents any  disclosures  that may be required by
           law,  particularly  those relating to the Adviser's status as a bank,
           and it will include in all such Fund documents any material  comments
           reasonably  made by the  Adviser  or  Portfolio.  The  Portfolio  and
           Adviser  will,  however,  in no way  be  liable  for  any  errors  or
           omissions in such  documents,  whether or not they make any objection
           thereto,  except to the extent such errors or  omissions  result from
           information provided by the Adviser or the Portfolio.  [The Exclusive
           Placement  Agent for the  Portfolio  will in no way be liable for any
           errors or omissions in such documents.] The Company will not make any
           other  written  or oral  representation  about the  Portfolio  or the

      (b)  Tax  Status.  The Fund will  qualify  for  treatment  as a  regulated
           investment  company  under  Subchapter  M of the Code for all periods
           during  which this  Agreement  is in  effect,  except to the extent a
           failure to so qualify  may result  from any action or omission of the
           Portfolio.

      (c)  Investment Securities. The Fund will own no investment security other
           than its Interest in the Portfolio.

      (d)  Proxy  Voting.  If  requested  to vote as a  shareholder  on  matters
           pertaining  to the  Portfolio  (other  than a vote by the  Company to
           continue  the  operation  of the  Portfolio  upon the  withdrawal  of
           another  investor  in the  Portfolio),  the  Company  will (i) call a
           meeting  of  shareholders  of the Fund  for the  purpose  of  seeking
           instructions from shareholders  regarding such matters, (ii) vote the
           Fund's Interest  proportionally  as instructed by Fund  shareholders,
           and (iii) vote the Fund's Interest with respect to the shares held by
           Fund  shareholders  who do not give voting  instructions  in the same
           proportion  as the  shares of Fund  shareholders  who do give  voting
           instructions.  The  Company  will  hold  each  such  meeting  of Fund
           shareholders in accordance with a timetable reasonably established by
           the Portfolio.

      (e)  Insurance.  The  Company  shall  at all  times  maintain  errors  and
           omissions  liability  insurance  with  respect  to the Fund  covering
           losses for  negligence  and wrongful  acts in an amount not less than
           $[____].

      (f)  Auditors.  In the event the  Fund's  independent  public  accountants
           differ from those of the Portfolio, the Fund shall be responsible for
           any costs and expenses  associated  with the need for the Portfolio's
           independent public  accountants to provide  information to the Fund's
           independent public accountants.

      (g)  Fund Name. The Company agrees on behalf of the Fund that the Fund may
           use the name  "PreservationPlus"  in its name  only so long as all of
           the Fund's  investable  assets are invested in the Portfolio.  If the
           Company  elects to  withdraw  or redeem  the Fund's  Interest  in the
           Portfolio, the Fund will immediately change its name.

4.2   INDEMNIFICATION BY SECURITY MANAGEMENT

      (a)  With respect to those  matters  listed in  subparagraphs  (i) through
           (vi) below,  Security Management will indemnify and hold harmless the
           Portfolio,  the Adviser  and their  respective  trustees,  directors,
           officers  and  employees  and each  other  person  who  controls  the
           Portfolio or the Adviser,  as the case may be,  within the meaning of
           Section  15  of  the  1933  Act  (each,   a  "Covered   Person"   and
           collectively, "Covered Persons"), against any and all losses, claims,
           demands, damages,  liabilities and expenses, joint or several, (each,
           a "Liability" and collectively,  the "Liabilities").  Unless Security
           Management  elects to assume the defense  pursuant to  paragraph  (b)
           Security  Management will bear the reasonable  cost of  investigating
           and  defending  against  any claims  therefor  and any  counsel  fees
           incurred in connection therewith.  Any or each Liability which arises
           out, is based upon or results from:

           (i)    any violation or alleged violation of the Securities Laws, any
                  other statute or common law or are incurred in connection with
                  or as a  result  of  any  formal  or  informal  administrative
                  proceeding or investigation by a regulatory agency, insofar as
                  such Liabilities  arise out of or are based upon the ground or
                  alleged  ground  that  any  direct  or  indirect  omission  or
                  commission  by the  Company  or the Fund  (either  during  the
                  course  of its  daily  activities  or in  connection  with the
                  accuracy  of its  representations  or its  warranties  in this
                  Agreement)  caused  or  continues  to cause the  Portfolio  to
                  violate any federal or state securities laws or regulations or
                  any other applicable domestic or foreign law or regulations or
                  common law duties or obligations,  but only to the extent that
                  such Liabilities do not arise out of and are not based upon an
                  omission or commission of the Portfolio or Adviser;

           (ii)   Security  Management  having  caused  the  Portfolio  to be an
                  association   taxable   as  a   corporation   rather   than  a
                  partnership; or

           (iii)  any  misstatement  of a  material  fact  or an  omission  of a
                  material   fact  in  the  Company's   registration   statement
                  (including amendments thereto) or included in Fund advertising
                  or sales  literature,  other than information  provided by the
                  Portfolio  or the Adviser or included in Fund  advertising  or
                  sales  literature  at  the  request  of the  Portfolio  or the
                  Adviser;

           (iv)   the  failure of any  representation  or  warranty  made by the
                  Company or Security Management to be accurate when made or the
                  failure of the Company or Security  Management  to perform any
                  covenant  contained  herein or to  otherwise  comply  with the
                  terms of this Agreement;

           (v)    any  unlawful  or  negligent  act  of  the  Company,  Security
                  Management or any director,  officer, employee or agent of the
                  Company or Security Management, whether such act was committed
                  against the Company, the Portfolio, Bankers Trust or any third
                  party;

           (vi)   any  Liability  of the Fund for  which the  Portfolio  is also
                  liable;  provided,  however,  that in no case  shall  Security
                  Management  be liable with  respect to any claim made  against
                  any  Covered  Person  unless  the  Covered  Person  shall have
                  notified  Security  Management in writing of the nature of the
                  claim within a reasonable time after the summons,  other first
                  legal process or formal or informal initiation of a regulatory
                  investigation  or  proceeding  shall have been  served upon or
                  provided to a Covered Person,  or any federal,  state or local
                  tax deficiency  has come to the attention of the Adviser,  the
                  Portfolio  or a Covered  Person.  Failure  to notify  Security
                  Management  of such  claim  shall  not  relieve  it  from  any
                  liability  that it may have to any  Covered  Person  otherwise
                  than  on  account  of the  indemnification  contained  in this
                  Section.

      (b)  Security  Management  will  be  entitled  to  participate  at its own
           expense in the defense or, if it so elects,  to assume the defense of
           any suit  brought to enforce  any such  liability,  but,  if Security
           Management  elects to  assume  the  defense,  such  defense  shall be
           conducted  by counsel  chosen by  Security  Management.  In the event
           Security Management elects to assume the defense of any such suit and
           retain such counsel,  each Covered Person and any other  defendant or
           defendants may retain additional counsel, but shall bear the fees and
           expenses of such counsel  unless (A) Security  Management  shall have
           specifically  authorized  the  retaining  of such  counsel or (B) the
           parties  to  such  suit  include  any  Covered  Person  and  Security
           Management,  and any such Covered  Person has been advised by counsel
           that one or more legal  defenses  may be available to it that may not
           be  available  to  Security   Management,   in  which  case  Security
           Management  shall not be  entitled to assume the defense of such suit
           notwithstanding  its obligation to bear the fees and expenses of such
           counsel.  Security  Management  shall not be liable to indemnify  any
           Covered  Person  for any  settlement  of any claim  affected  without
           Security  Management's  written  consent,  which consent shall not be
           unreasonably  withheld  or  delayed.  The  indemnities  set  forth in
           paragraph (a) will be in addition to any  liability  that the Company
           in respect of the Fund might otherwise have to a Covered Person.

4.3   INDEMNIFICATION BY SECURITY DISTRIBUTORS

      (a)  With respect to those matters listed in subparagraph (i) through (iv)
           below,   Security   Distributors  will  indemnify  and  harmless  the
           Portfolio,  the Adviser  and their  respective  trustees,  directors,
           officers  and  employees  and each  other  person  who  controls  the
           Portfolio or the Adviser,  as the case may be,  within the meaning of
           Section 15 of the 1933 Act (each a "Covered Person" and collectively,
           "Covered  Persons"),  against  any and all losses,  claims,  demands,
           damages,  liabilities  and  expenses,  joint  or  several,  (each,  a
           "Liability" and  collectively,  the  "Liabilities").  Unless Security
           Distributors  elects to assume the defense pursuant to paragraph (b),
           Security  Distributors will bear the reasonable cost of investigating
           and  defending  against  any claims  therefor  and any  counsel  fees
           incurred in connection therewith.  Any or each liability which arises
           out, is based upon or results from:

           (i)    any  misstatement  of a  material  fact  or an  omission  of a
                  material   fact   included  in  Fund   advertising   or  sales
                  literature,  other than information  provided by the Portfolio

                  literature at the request of the Portfolio or the Adviser;

           (ii)   the failure of any representation or warranty made by Security
                  Distributors  to be  accurate  when  made  or the  failure  of
                  Security Distributors to perform any covenant contained herein
                  or to otherwise comply with the terms of this Agreement;

           (iii)  any unlawful or negligent act of Security  Distributors or any
                  director,  officer,  employee  or  agent  of  the  Company  or
                  Security Distributors,  whether such act was committed against
                  the Company, the Portfolio,  Bankers Trust or any third party;
                  or

           (iv)   any breach of the  representations,  warranties  and covenants
                  included herein,  including the representations  that the Fund
                  will permit  investments  only by IRAs and Plans as defined in
                  the  prospectus  for the BT  PreservationPlus  Income Fund and
                  that the redemption rights of shareholders of the Fund will be
                  the  same as  those  described  in the  prospectus  for the BT
                  PreservationPlus Income Fund.

      (b)  Security  Distributors  will be  entitled to  participate  at its own
           expense in the defense or, if it so elects,  to assume the defense of
           any  suit  brought  to  enforce  any  such  liability.   If  Security
           Distributors  elects to assume the  defense,  such  defense  shall be
           conducted by counsel  chosen by Security  Distributors.  In the event
           Security  Distributors  elects to assume the defense of any such suit
           and retain such counsel,  each Covered Person and any other defendant
           or defendants may retain additional counsel,  but shall bear the fees
           and expenses of such counsel unless (A) Security  Distributors  shall
           have specifically authorized the retaining of such counsel or (B) the
           parties  to  such  suit  include  any  Covered  Person  and  Security
           Distributors, and any such Covered Person has been advised by counsel
           that one or more legal  defenses  may be available to it that may not
           be  available  to  Security  Distributors,  in  which  case  Security
           Distributors shall not be entitled to assume the defense of such suit
           notwithstanding  its obligation to bear the fees and expenses of such
           counsel.  Security  Distributors shall not be liable to indemnify any
           Covered  Person  for any  settlement  of any claim  affected  without
           Security  Distributors'  written  consent.  Such consent shall not be
           unreasonably  withheld  or  delayed.  The  indemnities  set  forth in
           paragraph (a) will be in addition to any  liability  that the Company
           in respect of the Fund might otherwise have to a Covered Person.

      (c)  Any breach of the representations,  warranties and covenants included
           herein  (including  the  representations  that the Fund  will  permit
           investments  only by IRAs and Plans (as defined in the prospectus for
           the BT  PreservationPlus  Income Fund) and that the redemption rights
           of  shareholders  of the Fund will be the same as those  described in
           the  prospectus  for  the  BT  PreservationPlus   Income  Fund)  will
           constitute  a request  for the  partial  or  complete  redemption  of
           Portfolio interests by the Company.

4.4   THE PORTFOLIO

The Portfolio covenants that:

      (a)  Advance Review of Certain  Documents.  The Portfolio will furnish the
           Company and Security  Management,  at least 10 business days prior to
           filing  or  first  use,  as the  case  may  be,  with  drafts  of its
           registration  statement  on  Form  N-1A  (including  amendments)  and
           prospectus supplements or amendments. The Portfolio will not make any
           written  or  oral  representation   about  the  Company  or  Security
           Management without their prior written consent.

      (b)  Tax Status. The Portfolio will qualify to be taxable as a partnership
           under the Code for all  periods  during  which this  Agreement  is in
           effect,  except to the extent that the failure to so qualify  results

      (c)  Insurance.  The  Portfolio  shall at all times  maintain  errors  and
           omissions  liability  insurance  covering  losses for  negligence and
           wrongful acts in an amount not less than $10 million.

      (d)  Availability  of Interests.  Conditional  upon the Company  complying
           with the terms of this Agreement, the Portfolio shall permit the Fund
           to make additional  Investments in the Portfolio on each business day
           on  which  shares  of the  Fund  are  sold to the  public;  provided,
           however,  that the  Portfolio  may  refuse to permit the Fund to make
           additional Investments in the Portfolio on any day on which:

           (i)    the Portfolio has refused to permit all other investors in the
                  Portfolio to make additional investments in the Portfolio, or

           (ii)   the Trustees of the Portfolio have reasonably  determined that
                  permitting additional investments by the Fund in the Portfolio
                  would  constitute  a breach of their  fiduciary  duties to the
                  Portfolio.

4.5   INDEMNIFICATION BY THE ADVISER

      (a)  With respect to those  matters  listed in  subparagraphs  (i) through
           (viii)  below,  the Adviser  will  indemnify  and hold  harmless  the
           Company,  Security Management,  their respective directors,  officers
           and  employees  and each other person who  controls the Company,  the
           Fund or Security  Management,  as the case may be, within the meaning
           of  Section  15 of  the  1933  Act  (each,  a  "Covered  Person"  and
           collectively, "Covered Persons"), against any and all losses, claims,
           demands, damages,  liabilities and expenses, joint or several, (each,
           a  "Liability"  and  collectively,  the  "Liabilities").  Unless  the
           Adviser  elects to assume the defense  pursuant to paragraph  (b) the
           Adviser will bear the reasonable costs of investigating and defending
           against  any  claims  therefore  and any  counsel  fees  incurred  in
           connection  therewith),  whether incurred  directly by the Company or
           Security   Management  or  indirectly  by  the  Company  or  Security
           Management through the Company's Investment in the Portfolio.  Any or
           each Liability which arises out, is based upon or results from:

           (i)    any of the Securities Laws, any other statute or common law or
                  are incurred in  connection  with or as a result of any formal
                  or informal  administrative  proceeding or  investigation by a
                  regulatory agency, insofar as such Liabilities arise out of or
                  are based upon the ground or alleged ground that any direct or
                  indirect  omission  or  commission  by the  Portfolio  (either
                  during the  course of its daily  activities  or in  connection
                  with the accuracy of its  representations or its warranties in
                  this  Agreement)  caused or  continues to cause the Company to
                  violate any federal or state securities laws or regulations or
                  any other applicable domestic or foreign law or regulations or
                  common law duties or obligations,  but only to the extent that
                  such Liabilities do not arise out of and are not based upon an
                  omission or commission of the Company or Security Management;

           (ii)   an inaccurate  calculation of the  Portfolio's net asset value
                  (whether by the  Portfolio,  the Adviser or any party retained
                  for that purpose);

           (iii)  (A) any  misstatement  of a material  fact or an omission of a
                  material  fact  in  the  Portfolio's   registration  statement
                  (including amendments thereto) or included at the Adviser's or
                  Portfolio's request in advertising or sales literature used by
                  the Fund,  or (B) any  misstatement  of a material  fact or an
                  omission of a material fact in the  registration  statement or
                  advertising  or  sales  literature  of  any  investor  in  the
                  Portfolio, other than the Company;

           (iv)   the Portfolio's having caused the Fund to fail to qualify as a
                  regulated investment company under the Code;

           (v)    failure  of  any   representation  or  warranty  made  by  the
                  Portfolio  or Adviser to be accurate  when made or the failure
                  of the Portfolio or Adviser to perform any covenant  contained
                  herein  or  to  otherwise   comply  with  the  terms  of  this
                  Agreement;

           (vi)   any unlawful or negligent act by the Portfolio, the Adviser or
                  any  director,  trustee,  officer,  employee  or  agent of the
                  Portfolio or Adviser,  whether such act was committed  against
                  the Portfolio,  the Company,  Security Management or any third
                  party;

           (vii)  any claim that the systems,  methodologies, or technology used
                  in  connection  with  operating the  Portfolio,  including the
                  technologies  associated with  maintaining  the  master-feeder
                  structure of the Portfolio,  violates any license or infringes
                  upon any patent or trademark;

           (viii) any  Liability  of  the  Portfolio  to  any  investor  in  the
                  Portfolio (or shareholder  thereof),  other than the Fund (and
                  its shareholders);  provided,  however,  that in no case shall
                  the Adviser be liable with  respect to any claim made  against
                  any such Covered  Person unless such Covered Person shall have
                  notified  the  Adviser  in  writing of the nature of the claim
                  within a reasonable time after the summons,  other first legal
                  process  or  formal or  informal  initiation  of a  regulatory
                  investigation  or  proceeding  shall have been  served upon or
                  provided to a Covered  Person or any  federal,  state or local
                  tax  deficiency  has  come to the  attention  of the  Company,
                  Security Management or a Covered Person. Failure to notify the
                  Adviser of such claim shall not relieve it from any  liability
                  that  it may  have to any  Covered  Person  otherwise  than on
                  account of the indemnification contained in this paragraph.

      (b)  The Adviser will be entitled to participate at its own expense in the
           defense or, if it so elects to assume the defense of any suit brought
           to enforce any such  liability.  If the Adviser  elects to assume the
           defense,  such defense  shall be  conducted by counsel  chosen by the
           Adviser. In the event the Adviser elects to assume the defense of any
           such suit and retain such counsel,  each Covered Person and any other
           defendant or defendants in the suit may retain additional counsel but
           shall  bear the fees and  expenses  of such  counsel  unless  (A) the
           Adviser  shall have  specifically  authorized  the  retaining of such
           counsel or (B) the parties to such suit  include  any Covered  Person
           and the  Adviser,  and any such  Covered  Person has been  advised by
           counsel  that one or more legal  defenses may be available to it that
           may not be available to the Adviser,  in which case the Adviser shall
           not be entitled  to assume the  defense of such suit  notwithstanding
           the  obligation  to bear the fees and expenses of such  counsel.  The
           Adviser shall not be liable to indemnify  any Covered  Person for any
           settlement of any such claim effected  without the Adviser's  written
           consent.  Such consent shall not be unreasonably withheld or delayed.
           The indemnities set forth in paragraph (a) will be in addition to any
           liability  that  the  Portfolio  might  otherwise  have to a  Covered
           Person.

4.6   SCOPE OF AGREEMENT

Nothing  contained  herein shall be construed to protect any person  against any
liability to which such person  would  otherwise be subject by reason of willful
misfeasance,  bad faith,  or  negligence,  in the  performance  of such person's
duties,  or be reason  of such  person's  reckless  disregard  of such  person's
obligations under such contract or agreement.

4.7   IN-KIND REDEMPTION

In the event the  Company  desires to withdraw or redeem all or a portion of the
Fund's  Interests in the Portfolio,  unless  otherwise agreed to by the parties,
the  Portfolio  will  effect  such  redemption  (i) in cash,  (ii) "in kind" (as
described below) or (iii) in some combination of the foregoing determined solely
in the  discretion  of the Adviser.  Further,  if the  Interest  Rate Trigger as
described  in the  Prospectus  for the  Portfolio is active,  a  redemption  fee
(currently 3% of the proceeds of such redemption) will be applied. In connection
with a partial or complete  payment "in kind",  the Portfolio will distribute to
the Company securities and Wrapper Agreements as described in the prospectus for
the BT  PreservationPlus  Income Fund.  The Portfolio will assign to the Company
one or more  Wrapper  Agreements  issued by the Wrapper  providers  covering the
securities  distributed  in  kind.  The  terms  and  conditions  of the  Wrapper
Agreements distributed to the Company will be substantially similar to the terms
and  conditions of the Wrapper  Agreements  held by the  Portfolio.  In order to
obtain  the  benefits  provided  thereunder,  the  Company's  management  of the
securities must be consistent with the Wrapper  Agreement  requirements  and the
Company must complete the  assignment by executing  the Wrapper  Agreements.  No
other  withdrawal  or  redemption  of any  Interest  in the  Portfolio  will  be
satisfied by means of an "in kind"  redemption  except in  compliance  with Rule
18f-1 under the 1940 Act,  provided,  however,  that for purposes of determining
compliance with Rule 18f-1, each shareholder of the Fund redeeming shares of the
Fund on a  particular  day will be treated as a direct  holder of an Interest in
the Portfolio being redeemed that day.

4.8   REASONABLE ACTIONS

Each party covenants that it will,  subject to the provisions of this Agreement,
from  time to  time,  as and  when  requested  by  another  party  or in its own
discretion,  as the case may be, execute and deliver or cause to be executed and
delivered all such assignments and other instruments,  take or cause to be taken
such actions, and do or cause to be done all things reasonably necessary, proper
or  advisable  in order to  consummate  the  transactions  contemplated  by this
Agreement and to carry out its intent and purpose.

           (i)    any  representation or warranty contained in this Agreement to
                  be untrue or inaccurate, or

           (ii)   any condition precedent set forth in Article Five hereof to be
                  unsatisfied  in  any  material  respect  at  the  time  of any

disclose such  information  to others  without the prior written  consent of the

any other regulatory body or the Fund's or Portfolio's  respective auditors,  or

         Bankers,  a certificate  signed by Fund's president or other officer of
         Fund,  or other  authorized  individual,  as  reasonably  requested  by
         Bankers.  Fund shall also provide to Bankers  instructions with respect

         such Confidential Information to Bankers upon termination or expiration
         of this Agreement.

    (g)  If  Bankers  shall  provide  Fund  direct  access  to the  computerized
         recordkeeping  and  reporting  system used  hereunder or if Bankers and
         Fund shall agree to utilize  any  electronic  system of  communication,
         Fund shall be fully responsible for any and all consequences of the use
         or misuse of the terminal device,  passwords,  access  instructions and
         other means of access to such system(s) which are utilized by, assigned
         to or otherwise  made  available to the Fund.  Fund agrees to implement
         and enforce  appropriate  security  policies and  procedures to prevent
         unauthorized or improper  access to or use of such  system(s).  Bankers
         shall be fully  protected in acting  hereunder  upon any  instructions,
         communications,  data or other information  received by Bankers by such
         means as fully and to the same  effect as if  delivered  to  Bankers by
         written instrument signed by the requisite authorized representative(s)
         of the Fund.

              hereunder or of any other electronic system of communication  used
              hereunder  by Fund or by any  person who  acquires  access to such

    order, decree or agreement by which the Fund may be bound.

         hold  the  same  in  custody  in  its  form  and  condition  as of  the
         termination   date,   and  Bankers  shall  be  entitled  to  reasonable
         compensation  therefor,  including  but  not  limited  to  all  of  its
         out-of-pocket costs and expenses incurred in connection therewith.

   WHEREAS,  the Fund desires to engage the Manager to provide certain  services
to the Series; and

   WHEREAS,  the Manager is willing, in accordance with the terms and conditions
hereof, to provide such services to the Series; and

   NOW THEREFORE, in consideration of the mutual agreements set forth herein and
intending to be legally bound hereby, the parties agree as follows:

1.  APPOINTMENT AND DUTIES OF MANAGER

    (a)  The Fund,  on behalf of the  Series,  hereby  employs  the  Manager  to
         perform  the  services  set  forth in this  Agreement,  subject  to the
         supervision  of the Board of Directors of the Fund,  for the period and

         such  employment  and undertakes to pay the salaries and expense of all
         personnel of the Manager who perform services  relating to the services
         it performs  hereunder.  The Manager  shall for all purposes  herein be
         deemed to be an independent  contractor and shall,  except as otherwise
         expressly  provided  or  authorized,  have no  authority  to act for or
         represent  the Fund in any way or  otherwise  be deemed an agent of the
         Fund.

    (b)  Notwithstanding the foregoing,  the Manager shall not be deemed to have
         assumed  any duties  hereunder  with  respect to, and shall not, by the
         execution of this Agreement be  responsible  for, the management of the
         Funds'  assets or the rendering of  investment  advice and  supervision
         with respect  thereto,  or the distribution of shares of the Funds, nor
         shall  the  Manager  be  deemed  to  have  assumed  any  responsibility
         hereunder  with  respect  to  functions  specifically  assumed  by  any
         administrator, transfer agent, custodian or shareholder servicing agent
         of the Fund or the Series.

    (c)  Without  limiting the  generality of the  foregoing,  the Manager shall
         provide the  following  services to the Series (as well as the services
         set forth in Section1(d) below):

           i.  Provide  information to and  coordinate the Series'  relationship
               with  registered   investment   advisors  and  other   securities
               professionals  who  have  discretionary   authority  over  Series
               shareholder   accounts,   assist  in  facilitating   instructions
               received by such  persons  relating to Fund  business and furnish
               facilities and personnel necessary to perform such activities.

          ii.  Assist as  appropriate  and  coordinate  with the Fund's  service
               providers in administering  the affairs of the Series and perform
               services on the Series' behalf.

         iii.  Pay the salaries  and  expenses of all officers and  Directors of
               the Fund who are employees of the Manager.

    (d)  It is  intended  that the assets of the Series  will be  invested  in a
         portfolio (the  Portfolio")  having  substantially  the same investment
         objective,  policies and restrictions as the Series. In addition to its
         duties  hereunder,  set forth in paragraph 1(c), above, with respect to
         the Series, the Manager shall perform the following:

           i.  Monitor the performance of the Portfolio;

          ii.  Coordinate the relationship of the Series with the Portfolio;

         iii.  Communicate with the Board of Directors of the Fund regarding the
               performance of the Portfolio and the Series;

     responsibilities  or duties under this  agreement.  SMC shall not be liable

     may be the subject of indemnification  hereunder.  In the event the Fund so
     elects,  it will so  notify  SMC and  thereupon  the Fund  shall  take over
     defenses of the claim, and (if so requested by the Fund, SMC shall incur no
     further  legal  or  other  claims  related  thereto  for  which it would be
     entitled to indemnity  hereunder  provided,  however,  that nothing  herein

     defend any claim.  Except with the Fund's  prior  consent,  SMC shall in no
     event  confess any claim or make any  compromise in any matter in which the
     Fund will be asked to indemnify or hold SMC harmless hereunder.

         party,  for punitive,  exemplary,  indirect,  special or  consequential

         damages)  arising from its obligations and the services  provided under
         this agreement,  including but not limited to loss of profits,  loss of

         limited to acts of civil or military authority,  national  emergencies,

         insurrection, war, riot, failure of communication or interruption.

     SMC may, at its  discretion,  delegate,  assign or  subcontract  any of the
     duties,  responsibilities  and services governed by this agreement,  to its
     parent  company,  Security  Benefit Group,  Inc.,  whether or not by formal
     written agreement.  SMC shall, however,  retain ultimate  responsibility to
     the  Fund,  and  shall  implement  such  reasonable  procedures  as  may be
     necessary,  for assuring that any duties,  responsibilities  or services so
     assigned,  subcontracted  or delegated are performed in conformity with the
     terms and conditions of this agreement.

 8.  AMENDMENT

     This  agreement and the  schedules  forming a part hereof may be amended at
     any time, without shareholder  approval, by a writing signed by each of the
     parties hereto. Any change in the Fund's  registration  statements or other
     documents of  compliance or in the forms  relating to any plan,  program or
     service offered by its current  prospectus  which would require a change in
     SMC's obligations hereunder shall be subject to SMC's approval, which shall
     not be unreasonably withheld.

 9.  TERMINATION

     This  agreement  may be  terminated  by either party without cause upon 120
     days' written  notice to the other,  and at any time for cause in the event
     that such cause remains  unremedied  for more than 30 days after receipt by
     the other party of written specification of such cause.

     In the  event  Fund  designates  a  successor  to any of SMC's  obligations
     hereunder,  SMC shall,  at the expense and pursuant to the direction of the
     Fund, transfer to such successor all relevant books, records and other data
     of Fund in the possession or under the control of SMC.

10.  SEVERABILITY

     If any clause or provision of this  agreement is  determined to be illegal,

     herefrom and the remainder of this  agreement  shall continue in full force

                                     CLASS B
                                DISTRIBUTION PLAN


1.  THE PLAN. This Distribution Plan (the "Plan"), provides for the financing by
    Security Income Fund (the "Fund") of activities  which are, or may be deemed
    to be,  primarily  intended  to  result in the sale of class B shares of the
    Fund (hereinafter called "distribution-related  activities").  The principal
    purpose of this Plan is to enable  the Fund to  supplement  expenditures  by
    Security   Distributors,   Inc.,   the   Distributor   of  its  shares  (the
    "Distributor") for distribution-related activities. This Plan is intended to
    comply with the requirements of Rule 12b-1 (the "Rule") under the Investment
    Company Act of 1940 (the "1940 Act").

    The Board of Directors, in considering whether the Fund should implement the
    Plan, has requested and evaluated such information as it deemed necessary to
    make an informed  determination as to whether the Plan should be implemented
    and has considered such pertinent factors as it deemed necessary to form the
    basis for a decision to use assets of the Fund for such purposes.

    In voting to approve the  implementation  of the Plan,  the  Directors  have
    concluded,  in the  exercise of their  reasonable  business  judgment and in
    light of their  respective  fiduciary  duties,  that  there is a  reasonable
    likelihood that the Plan will benefit the Fund and its shareholders.

2.  COVERED EXPENSES.

    (a)  The Fund may make payments  under this Plan, or any agreement  relating
         to the  implementation  of this Plan, in connection with any activities
         or expenses  primarily intended to result in the sale of class B shares
         of  the  Fund,   including,   but  not   limited   to,  the   following
         distribution-related activities:

           (i)  Preparation,  printing and  distribution  of the  Prospectus and
                Statement of Additional  Information and any supplement  thereto
                used in connection with the offering of shares to the public;

          (ii)  Printing  of  additional  copies for use by the  Distributor  as
                sales literature, of reports and other communications which were
                prepared by the Fund for distribution to existing shareholders;

         (iii)  Preparation,  printing  and  distribution  of  any  other  sales
                literature used in connection with the offering of shares to the
                public;

          (iv)  Expenses  incurred in advertising,  promoting and selling shares
                of the Fund to the public;

           (v)  Any fees paid by the Distributor to securities  dealers who have
                executed a Dealer's Distribution  Agreement with the Distributor
                for account  maintenance and personal service to shareholders (a
                "Service Fee");

          (vi)  Commissions  to sales  personnel for selling  shares of the Fund
                and interest expenses related thereto; and

         (vii)  Expenses  incurred in  promoting  sales of shares of the Fund by
                securities  dealers,  including  the  costs  of  preparation  of
                materials  for   presentations,   travel   expenses,   costs  of
                entertainment,  and other expenses  incurred in connection  with
                promoting sales of Fund shares by dealers.

    (b)  Any payments for distribution-related activities shall be made pursuant
         to an agreement.  As required by the Rule,  each agreement  relating to
         the  implementation  of this Plan  shall be in writing  and  subject to
         approval and  termination  pursuant to the  provisions  of Section 7 of
         this Plan. However,  this Plan shall not obligate the Fund or any other
         party to enter into such agreement.

3.  AGREEMENT WITH DISTRIBUTOR. All payments to the Distributor pursuant to this
    Plan shall be subject to and be made in compliance with a written  agreement
    between  the  Fund  and the  Distributor  containing  a  provision  that the
    Distributor  shall furnish the Fund with  quarterly  written  reports of the
    amounts expended and the purposes for which such  expenditures were made and
    such  other  information  relating  to  such  expenditures  or to the  other
    distribution-related  activities  undertaken or proposed to be undertaken by
    the  Distributor  during such fiscal year under its  Distribution  Agreement
    with the Fund as the Fund may reasonably request.

4.  DEALER'S DISTRIBUTION  AGREEMENT.  The Dealer's Distribution  Agreement (the
    "Agreement")  contemplated  by Section 2(a)(v) above shall permit payment of
    Service Fees to  securities  dealers by the  Distributor  only in accordance
    with the  provisions  of this  paragraph  and shall have the approval of the
    majority of the Board of Directors of the Fund,  including  the  affirmative
    vote of a majority of those Directors who are not interested  persons of the
    Fund and who have no direct or indirect  financial interest in the operation
    of the Plan or any agreement related to the Plan ("Independent  Directors"),
    as required by the Rule. The  Distributor  may pay to the other party to any
    Agreement a Service Fee for distribution and marketing  services provided by
    such other party.  Such Service Fee shall be payable (a) for the first year,
    initially,  in any amount equal to .25 percent annually of the aggregate net
    asset  value of the shares  purchased  by such other  party's  customers  or
    clients,  and (b) for each year  thereafter,  quarterly,  in  arrears  in an
    amount equal to such percentage (not in excess of .000685 percent per day or
    .25 percent annually) of the aggregate net asset value of the shares held by
    such other party's customers or clients at the close of business each day as
    determined  from  time to  time by the  Distributor.  The  distribution  and
    marketing services  contemplated  hereby shall include,  but are not limited
    to,  answering  inquiries  regarding  the  Fund,  account  designations  and
    addresses,  maintaining  the  investment of such other party's  customers or
    clients in the Fund and similar services.  In determining the extent of such
    other party's  assistance in maintaining such investment by its customers or
    clients,  the  Distributor  may take into account the  possibility  that the
    shares held by such  customer or client  would be redeemed in the absence of
    such fee.

5.  LIMITATIONS  ON  COVERED  EXPENSES.  The basic  limitation  on the  expenses
    incurred by the Fund under Section 2 of this Plan  (including  Service Fees)
    in any fiscal  year of the Fund shall be one  percent  (1.00%) of the Fund's
    average  daily net assets for such  fiscal  year.  The  payments  to be paid
    pursuant to this Plan shall be calculated and accrued daily and paid monthly
    or at such other intervals as the Directors shall determine,  subject to any
    applicable  restriction  imposed  by rules of the  National  Association  of
    Securities Dealers, Inc.

6.  INDEPENDENT  DIRECTORS.  While this Plan is in  effect,  the  selection  and
    nomination  of  Independent  Directors of the Fund shall be committed to the
    discretion of the  Independent  Directors.  Nothing herein shall prevent the
    involvement of others in such selection and nomination if the final decision
    on any such  selection  and  nomination  is  approved  by a majority  of the
    Independent Directors.

7.  EFFECTIVENESS,  CONTINUATION,  TERMINATION AND AMENDMENT. This Plan and each
    Agreement  relating to the  implementation of this Plan shall go into effect
    when approved.

    (a)  By vote of the Fund's  Directors,  including the affirmative  vote of a
         majority  of the  Independent  Directors,  cast in  person at a meeting
         called for the purpose of voting on the Plan or the Agreement;

    (b)  By a vote of holders of at least a majority of the  outstanding  voting
         securities of the Fund; and

    (c)  Upon the  effectiveness  of an  amendment  to the  Fund's  registration
         statement, reflecting this Plan, filed with the Securities and Exchange
         Commission under the Securities Act of 1933.

    This Plan and any  Agreements  relating to the  implementation  of this Plan
    shall,  unless terminated as hereinafter  provided,  continue in effect from
    year to year only so long as such  continuance is  specifically  approved at
    least annually by vote of the Fund's  Directors,  including the  affirmative
    vote of a majority of its Independent Directors, cast in person at a meeting
    called  for the  purpose  of voting on such  continuance.  This Plan and any
    Agreements relating to the implementation of this Plan may be terminated, in
    the case of the plan, at any time or, in the case of any agreements upon not
    more  than  sixty  (60)  days'  written  notice  to any  other  party to the
    Agreement by vote of a majority of the Independent  Directors or by the vote
    of the holders of a majority of the  outstanding  voting  securities  of the
    Fund.  Any  Agreement  relating  to the  implementation  of this Plan  shall
    terminate  automatically in the event it is assigned. Any material amendment
    to this  Plan  shall  require  approval  by vote  of the  Fund's  Directors,
    including the affirmative  vote of a majority of the Independent  Directors,
    cast in  person  at a  meeting  called  for the  purpose  of  voting on such
    amendment and, if such  amendment  materially  increases the  limitations on
    expenses payable under the Plan, it shall also require approval by a vote of
    holders of at least a majority of the outstanding  voting  securities of the
    Fund. As applied to the Fund the phrase "majority of the outstanding  voting
    securities"  shall have the meaning  specified  in Section  2(a) of the 1940
    Act.

    In the event this Plan should be terminated by the shareholders or Directors
    of the Fund, the payments paid to the Distributor pursuant to the Plan up to
    the date of termination  shall be retained by the Distributor.  Any expenses
    incurred by the  Distributor  in excess of those  payments  will be the sole
    responsibility of the Distributor.

8.  RECORDS.  The Fund  shall  preserve  copies  of this  Plan  and any  related
    Agreements  and all reports made pursuant to Section 3 hereof,  for a period
    of not  less  than  six (6)  years  from  the  date of this  Plan,  any such
    Agreement or any such report,  as the case may be, the first two years in an
    easily accessible place.

                              SECURITY INCOME FUND
                                     CLASS C
                                DISTRIBUTION PLAN

1.   THE PLAN. This Distribution  Plan (the "Plan"),  provides for the financing
     by Security  Income Fund (the  "Fund") of  activities  which are, or may be
     deemed to be, primarily intended to result in the sale of class C shares of
     the  Fund  (hereinafter  called  "distribution-related   activities")  with
     respect  to those  Series of the Fund set forth in  Appendix  A to the Plan
     (referred to herein as the "Series"). Appendix A, as it may be amended from
     time to time, is incorporated herein by reference. The principal purpose of
     this Plan is to enable  the Fund to  supplement  expenditures  by  Security
     Distributors,  Inc., the Distributor of its shares (the  "Distributor") for
     distribution-related  activities.  This Plan is intended to comply with the
     requirements of Rule 12b-1 (the "Rule") under the Investment Company Act of
     1940 (the "1940 Act").

     The Board of Directors,  in considering  whether the Fund should  implement
     the  Plan,  has  requested  and  evaluated  such  information  as it deemed
     necessary to make an informed  determination  as to whether the Plan should
     be  implemented  and has  considered  such  pertinent  factors as it deemed
     necessary  to form the basis for a  decision  to use assets of the Fund for
     such purposes.

     In voting to approve the  implementation  of the Plan,  the Directors  have
     concluded,  in the exercise of their  reasonable  business  judgment and in
     light of their  respective  fiduciary  duties,  that there is a  reasonable
     likelihood that the Plan will benefit the Series and its shareholders.

2.   COVERED EXPENSES.

     (a)  The Fund may make payments under this Plan, or any agreement  relating
          to the  implementation of this Plan, in connection with any activities
          or expenses primarily intended to result in the sale of Class C shares
          of  the  Series,   including,   but  not  limited  to,  the  following
          distribution-related activities:

          (i)     Preparation,  printing and  distribution of the Prospectus and
                  Statement of Additional Information and any supplement thereto
                  used in connection  with the offering of Series' shares to the
                  public;

          (ii)    Printing of additional  copies for use by the  Distributor  as
                  sales literature,  of reports and other  communications  which
                  were  prepared  by  the  Fund  for  distribution  to  existing
                  shareholders;

          (iii)   Preparation,  printing  and  distribution  of any other  sales
                  literature  used in  connection  with the  offering of Series'
                  shares to the public;

          (iv)    Expenses incurred in advertising, promoting and selling shares
                  of the Series to the public;

          (v)     Any fees paid by the  Distributor  to  securities  dealers who
                  have  executed  a  Dealer's  Distribution  Agreement  with the
                  Distributor for account  maintenance  and personal  service to
                  shareholders (a "Service Fee");

          (vi)    Commissions  to sales  personnel  for  selling  shares  of the
                  Series and interest expenses related thereto; and

          (vii)   Expenses  incurred in promoting sales of shares of the Fund by
                  securities  dealers,  including  the costs of  preparation  of
                  materials  for  presentations,   travel  expenses,   costs  of
                  entertainment,  and other expenses incurred in connection with
                  promoting sales of Series shares by dealers.

     (b)  Any  payments  for  distribution-related   activities  shall  be  made
          pursuant to an  agreement.  As required  by the Rule,  each  agreement
          relating  to the  implementation  of this Plan shall be in writing and
          subject to approval  and  termination  pursuant to the  provisions  of
          Section 7 of this Plan. However, this Plan shall not obligate the Fund
          or any other party to enter into such agreement.

3.   AGREEMENT WITH  DISTRIBUTOR.  All payments to the  Distributor  pursuant to
     this Plan  shall be  subject  to and be made in  compliance  with a written
     agreement between the Fund and the Distributor  containing a provision that
     the  Distributor  shall furnish the Fund with quarterly  written reports of
     the amounts expended and the purposes for which such expenditures were made
     and such other  information  relating to such  expenditures or to the other
     distribution-related  activities undertaken or proposed to be undertaken by
     the Distributor  during such fiscal year under its  Distribution  Agreement
     with the Fund as the Fund may reasonably request.

4.   DEALER'S DISTRIBUTION  AGREEMENT.  The Dealer's Distribution Agreement (the
     "Agreement")  contemplated by Section 2(a)(v) above shall permit payment of
     Service Fees to securities  dealers by the  Distributor  only in accordance
     with the  provisions  of this  paragraph and shall have the approval of the
     majority of the Board of Directors of the Fund,  including the  affirmative
     vote of a majority of those Directors who are not interested persons of the
     Fund and who have no direct or indirect financial interest in the operation
     of the Plan or any agreement related to the Plan ("Independent Directors"),
     as required by the Rule. The  Distributor may pay to the other party to any
     Agreement a Service Fee for account  maintenance and  shareholder  services
     provided by such other party. Such Service Fee shall be payable (a) for the
     first year, initially,  in any amount equal to 0.25 percent annually of the
     aggregate  net asset value of the shares  purchased  by such other  party's
     customers  or  clients,  and (b) for each year  thereafter,  quarterly,  in
     arrears  in an amount  equal to such  percentage  (not in excess of .000685
     percent per day or 0.25 percent  annually) of the aggregate net asset value
     of the shares held by such other party's  customers or clients at the close
     of business  each day as determined  from time to time by the  Distributor.
     The distribution and marketing services  contemplated hereby shall include,
     but are not limited to, answering inquiries  regarding the Series,  account
     designations  and  addresses,  maintaining  the  investment  of such  other
     party's  customers  or  clients  in the Series  and  similar  services.  In
     determining the extent of such other party's assistance in maintaining such
     investment  by its  customers  or clients,  the  Distributor  may take into
     account the  possibility  that the shares  held by such  customer or client
     would be redeemed in the absence of such fee.

5.   LIMITATIONS  ON COVERED  EXPENSES.  The basic  limitation  on the  expenses
     incurred  by each Series of the Fund  identified  in Appendix A, other than
     the Capital  Preservation  Series under  Section 2 of this Plan  (including
     Service  Fees) in any fiscal year of the Fund shall be one percent  (1.00%)
     of the Fund's  average daily net assets for such fiscal year,  with respect
     to the Capital Preservation Series, shall be 0.50% (50 basis points) of its
     average  daily net assets  for its fiscal  year.  The  payments  to be paid
     pursuant  to this  Plan  shall be  calculated  and  accrued  daily and paid
     monthly  or at such  other  intervals  as the  Directors  shall  determine,
     subject to any applicable  restrictions imposed by the National Association
     of Securities Dealers, Inc.

6.   INDEPENDENT  DIRECTORS.  While this Plan is in effect,  the  selection  and
     nomination of  Independent  Directors of the Fund shall be committed to the
     discretion of the Independent  Directors.  Nothing herein shall prevent the
     involvement  of  others  in such  selection  and  nomination  if the  final
     decision on any such  selection and nomination is approved by a majority of
     the Independent Directors.

7.   EFFECTIVENESS,  CONTINUATION, TERMINATION AND AMENDMENT. This Plan and each
     Agreement  relating to the implementation of this Plan shall go into effect
     when approved.

     (a)  By vote of the Fund's  Directors,  including the affirmative vote of a
          majority  of the  Independent  Directors,  cast in person at a meeting
          called for the purpose of voting on the Plan or the Agreement;

     (b)  By a vote of holders of at least a majority of the outstanding  voting
          securities of the Fund; and

     (c)  Upon the  effectiveness  of an  amendment  to the Fund's  registration
          statement,  reflecting  this  Plan,  filed  with  the  Securities  and
          Exchange Commission under the Securities Act of 1933.

     This Plan and any Agreements  relating to the  implementation  of this Plan
     shall, unless terminated as hereinafter  provided,  continue in effect from
     year to year only so long as such  continuance is specifically  approved at
     least annually by vote of the Fund's  Directors,  including the affirmative
     vote of a  majority  of its  Independent  Directors,  cast in  person  at a
     meeting called for the purpose of voting on such continuance. This Plan and
     any  Agreements  relating  to  the  implementation  of  this  Plan  may  be
     terminated,  in the case of the  plan,  at any time or,  in the case of any
     agreements  upon not more than sixty (60) days' written notice to any other
     party to the Agreement by vote of a majority of the  Independent  Directors
     or by the vote of the  holders  of a  majority  of the  outstanding  voting
     securities of the Fund.  Any Agreement  relating to the  implementation  of
     this Plan shall terminate  automatically  in the event it is assigned.  Any
     material  amendment  to this Plan  shall  require  approval  by vote of the
     Fund's  Directors,  including  the  affirmative  vote of a majority  of the
     Independent  Directors,  cast in person at a meeting called for the purpose
     of voting on such amendment and, if such amendment materially increases the
     limitations  on  expenses  payable  under the Plan,  it shall also  require
     approval  by a vote of holders of at least a  majority  of the  outstanding
     voting  securities of the Fund. As applied to the Fund the phrase "majority
     of the outstanding  voting  securities" shall have the meaning specified in
     Section 2(a) of the 1940 Act.

     In the  event  this  Plan  should  be  terminated  by the  shareholders  or
     Directors of the Fund, the payments paid to the Distributor pursuant to the
     Plan up to the date of  termination  shall be retained by the  Distributor.
     Any expenses  incurred by the  Distributor in excess of those payments will
     be the sole responsibility of the Distributor.

8.   RECORDS.  The Fund  shall  preserve  copies  of this  Plan and any  related
     Agreements and all reports made pursuant to Section 3 hereof,  for a period
     of not  less  than six (6)  years  from  the  date of this  Plan,  any such
     Agreement or any such report, as the case may be, the first two years in an
     easily accessible place.
