PROSPECTUS

         Conseco Series Trust (the "Trust") is an investment  company  presently
consisting of five separate  portfolios (the "Portfolios") each having different
objectives, assets, liabilities and net asset values per share.

         The investment objectives of the Portfolios are as follows:

         COMMON STOCK PORTFOLIO seeks to provide a high total return  consistent
with  preservation of capital and a prudent level of risk primarily by investing
in  selected  equity  securities  and other  securities  having  the  investment
characteristics of common stocks.

          ASSET  ALLOCATION  PORTFOLIO  seeks a high  total  investment  return,
consistent  with the  preservation of capital and prudent  investment  risk. The
Portfolio seeks to achieve this objective by pursuing an active asset allocation
strategy  whereby  investments  are  allocated,  based upon thorough  investment
research,  valuation and analysis of market trends and the anticipated  relative
total return  available,  among various asset classes including debt securities,
equity securities, and money market instruments.

          GOVERNMENT SECURITIES PORTFOLIO seeks safety of capital, liquidity and
current  income  by  investing  primarily  in  securities  issued  by  the  U.S.
government or an agency or  instrumentality  of the U.S.  government,  including
mortgage-related securities.

          CORPORATE  BOND  PORTFOLIO  seeks  the  highest  level of income as is
consistent  with  preservation  of capital by investing  primarily in investment
grade debt securities.

          MONEY MARKET PORTFOLIO seeks current income  consistent with stability
of capital and liquidity. An investment in this Portfolio is neither insured nor
guaranteed  by the U.S.  government,  and  there  can be no  assurance  that the
Portfolio will be able to maintain a stable net asset value of $1.00 per share.

          The various  Portfolios may be used  independently  or in combination.
The investment policies of the respective  Portfolios are fundamental and cannot
be changed without a vote of their respective  shareholders.  The purpose of the
Trust  is to serve as the  investment  medium  for  variable  annuity  contracts
("Contracts")  offered by insurance  companies  (see "Purchase and Redemption of
Shares").  The  Portfolios'  shares will not be offered  directly to the public.
There is no assurance that any of the Portfolios  will achieve their  investment
objectives.

         Within the  limitations  described in the Prospectus for the applicable
Contract, a contract owner of a Contract (the "Owner") may allocate premiums and
reallocate investment value under his or her Contract among various divisions of
the separate  account,  which, in turn,  invest in the various  Portfolios.  The
assets of each Portfolio are  segregated  and an Owner's  interest is limited to
the Portfolio(s) selected.
   
         This Prospectus  sets forth  concisely the information  about the Trust
that an investor  should  know  before  investing.  A  Statement  of  Additional
Information  (the "SAI") dated May 1, 1998,  containing  additional  information
about the Trust, has been filed with the Securities and Exchange  Commission and
is incorporated by reference in this Prospectus in its entirety.  You may obtain
a copy of the SAI without  charge by calling or writing the Trust at the address
and telephone above.
    
INVESTORS SHOULD READ AND RETAIN THIS PROSPECTUS FOR FUTURE REFERENCE.

THESE  SECURITIES  HAVE NOT BEEN  AP-PROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE  COMMISSION NOR HAS THE COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY
OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                  THE DATE OF THIS PROSPECTUS IS MAY 1, 1998.

                                                                     1998

                                                                   PROSPECTUS
- --------------------------------------------------------------------------------

SUMMARY
         The Conseco Series Trust (the "Trust") was organized as a Massachusetts
business trust on November 15, 1982. The Trust is a no-load, open-end management
investment company registered with the Securities and Exchange  Commission under
the Investment  Company Act of 1940. The Trust is a "series" type of mutual fund
which issues  separate series of shares,  each of which  currently  represents a
separate diversified portfolio of investments.  The Trust's series of shares are
issued and  redeemed at net asset value  without a sales load.  This  Prospectus
offers shares of five portfolios  ("Portfolios") of the Trust, each with its own
investment objective or objectives and investment policies.

         The shares of the  Portfolios  are offered to  insurance  companies  in
order to fund  certain  of  their  separate  accounts  used to  support  various
variable annuity contracts (the "Contracts"). The rights of an insurance company
holding Trust shares for a separate account are different from the rights of the
owner  of  a  Contract.  The  terms  "shareholder"  or  "shareholders"  in  this
Prospectus  shall  refer to the  insurance  companies,  and not to any  Contract
owner.

         The Trust serves as the underlying  investment medium for sums invested
in  Contracts  issued by  Bankers  National  Life  Insurance  Company  ("Bankers
National")  and  Great  American  Reserve  Insurance  Company  ("Great  American
Reserve").  The Trust may,  however,  be used for other  purposes in the future,
such as funding Contracts issued by other insurance companies.  Trust shares are
not  offered  directly  to and may not be  purchased  directly by members of the
public.

         Conseco Capital Management,  Inc. (the "Adviser") serves as the Trust's
investment adviser. The Adviser supervises the Trust's management and investment
program,  performs a variety of administrative  services on behalf of the Trust,
and  pays all  compensation  of  officers  and  Trustees  of the  Trust  who are
affiliated  persons  of the  Adviser  or the  Trust.  The  Trust  pays all other
expenses incurred in the operation of the Trust,  including fees and expenses of
Trustees who are unaffiliated persons of the Adviser or the Trust.

         The  Adviser  has  agreed  to  limit  the  operating  expenses  of  the
Portfolios  so that the ratio of expenses  to net assets on an annual  basis for
the Common Stock Portfolio shall not exceed 0.80 percent;  the Asset  Allocation
Portfolio shall not exceed 0.75 percent; the Government Securities and Corporate
Bond Portfolios  shall not exceed 0.70 percent;  and the Money Market  Portfolio
shall not exceed 0.45 percent.

         Certain  Contract  values will vary with the investment  performance of
the  Portfolios  of the Trust.  Because  Contract  owners  will  allocate  their
investments  among  the  Portfolios,  prospective  purchasers  should  carefully
consider the  information  about the Trust and its Portfolios  presented in this
Prospectus before purchasing such a Contract.

         Trust Annual Expenses After  Reimbursement  (as a percentage of average
daily net assets):

Portfolios        Management Fees   Other Expenses   Total Expenses (1)
================================================================================
Common Stock (2)             .60%             .20%                 .80%
Asset Allocation (2)         .55%             .20%                 .75%
Government Securities        .50%             .20%                 .70%
Corporate Bond               .50%             .20%                 .70%
Money Market (2)             .25%             .20%                 .45%
================================================================================

(1)  The Trust's  Adviser has  voluntarily  agreed to  reimburse  all  expenses,
     including  management  fees, in excess of the  following  percentage of the
     average  annual  net  assets  of  each  listed  Portfolio,  so long as such
     reimbursement would not result in the Portfolio's inability to qualify as a
     regulated  investment company under the Internal Revenue Code: 0.80 percent
     for Common  Stock;  0.75  percent for Asset  Allocation;  0.70  percent for
     Government  Securities  and  Corporate  Bond;  and 0.45  percent  for Money
     Market.   The  total   percentage   in  the  table  is  after  any  expense
     reimbursement. In the absence of expense reimbursement,  the total fees and
     expenses in 1997 would have  totaled:  0.80  percent  for the Common  Stock
     Portfolio;  0.84 percent for the Asset Allocation  Portfolio;  0.92 percent
     for the  Government  Securities  Portfolio;  0.77 percent for the Corporate
     Bond Portfolio; and 0.52 percent for the Money Market Portfolio.

(2)  The Trust's  Adviser,  since January 1, 1993,  has  voluntarily  waived its
     Management Fees in excess of the annual rates set forth above.  Absent such
     fee  waivers,  the  Management  Fees would be:  0.65% for the Common  Stock
     Portfolio;  0.65% for the  Asset  Allocation  Portfolio;  and 0.50% for the
     Money Market Portfolio.

     The above table reflects estimates of expenses of the Trust's Portfolios.

INVESTMENT OBJECTIVES AND POLICIES OF THE PORTFOLIOS
         Each  of  the  Portfolios  has  a  different  investment  objective  as
described  below.  Each  Portfolio  is managed by the  Adviser.  There can be no
assurance that any of the Portfolios will achieve its investment objective. Each
Portfolio is subject to the risk of changing economic conditions, as well as the
risk  inherent in the ability of the  Adviser to make  changes in a  Portfolio's
investments  in  anticipation  of changes in economic,  business,  and financial
conditions.

         The different types of securities and investment  techniques  common to
one or more Portfolios all have attendant risks of varying degrees. For example,
with  respect  to  equity  securities,  there  can be no  assurance  of  capital
appreciation  and there is a substantial  risk of decline.  With respect to debt
securities, there can be no assurance that the issuer of such securities will be
able to meet its  obligations  on  interest  or  principal  payments in a timely
manner.  In addition,  the value of debt  instruments  generally rises and falls
inversely with interest rates.

         Each of the Funds may invest in restricted  securities  such as private
placements,  although a Fund may not invest in any  restricted  security that is
illiquid  if,  after  acquisition  thereof,  more than 15  percent of the Fund's
assets  would be invested  in illiquid  securities.  Once  acquired,  restricted
securities may be sold by a fund only in privately negotiated transactions or in
a public  offering with respect to which a  registration  statement is in effect
under  the  Securities  Act  of  1933  ("1933  Act").  As a  result,  restricted
securities, once acquired, may be more difficult to sell and may sell at a price
that is less favorable than anticipated.

         The Funds may invest in securities  traded  pursuant to Rule 144A under
the 1933 Act (Rule 144A permits qualified  institutional buyers to trade certain
securities even though they are not registered under the 1933 Act). The Adviser,
acting  pursuant  to  guidelines  established  by the  Board  of  Trustees,  may
determine that some Rule 144A securities are liquid.

         The  investments  and  investment  techniques  common  to one  or  more
Portfolios are described in greater detail,  including the risks of each, in the
"Description of Securities and Investment Techniques" in the SAI.

         The  Portfolios  are  subject  to  investment   restrictions  that  are
described   under   "Investment   Restrictions"   in  the  SAI.  The  investment
restrictions  are  "fundamental  policies,"  which  means  that  they may not be
changed without a majority vote of shareholders of the affected  Portfolios.  In
addition, the Investment Company Act of 1940 (the "1940 Act") sets forth certain
requirements for open-end, diversified,  management investment companies such as
the Trust which are also  "fundamental  policies."  The more  important of these
restrictions  prohibits each Portfolio,  with respect to 75 percent of its total
assets,  from (i) investing  more than 5 percent of its assets in the securities
of any one issuer (except U.S.  government  securities  defined below); and (ii)
investing more than 25 percent of its assets in the securities of issuers in the
same industry  (except cash equivalent  items and U.S.  government  securities).
Except  for  fundamental  policies  imposed  either  by the  Trust's  investment
restrictions or by the 1940 Act, all investment policies and practices described
in this Prospectus and in the SAI are not fundamental, meaning that the Board of
Trustees may change them  without  shareholder  approval.  See  "Description  of
Securities and Investment  Techniques" and "Investment  Restrictions" in the SAI
for further information.

COMMON STOCK PORTFOLIO
         In seeking  its  objective  of  providing a high  equity  total  return
consistent  with the  preservation  of capital and a prudent level of risk,  the
Common  Stock  Portfolio  will attempt to achieve a total  return  (i.e.,  price
appreciation  plus potential  dividend yield)  primarily  through  investment in
selected  equities  (i.e.,   common  stocks  and  other  securities  having  the
investment  characteristics of common stocks, such as convertible debentures and
warrants).  However,  if market  conditions  indicate  their  desirability,  the
Adviser may, for  defensive  purposes,  temporarily  invest all or a part of the
assets of the Common Stock  Portfolio in money  market  instruments.  See "Money
Market Portfolio" below, and "Debt Securities" under  "Description of Securities
and Investment Techniques" in the SAI for further information.
   
         The Adviser  expects that the equity  portion of the Portfolio  will be
widely  diversified by both industry and number of issuers.  The Adviser's stock
selection  methods will be based in part upon the analysis of variables which it
believes  significantly relate to the future market performance of a stock, such
as recent  changes in 
    

                                       11
<PAGE>
- --------------------------------------------------------------------------------

   
earnings per share and their deviations from analysts' expectations, past growth
trends, price action of the stock itself, publicly recorded trading transactions
by corporate insiders,  and relative  price-earnings ratios. The Adviser expects
that investment  opportunities  will often be sought among securities of larger,
established companies, although securities of smaller, less well-known companies
may also be  selected.  Small  company  stocks have higher risk and  volatility,
because most are not as broadly traded as stocks of larger  companies,  and thus
their prices may fluctuate more widely and abruptly.

         By investing in securities  that are subject to market risk, the Common
Stock Portfolio is also subject to greater  fluctuations in its market value and
involves the  assumption  of a higher  degree of risk as compared to a portfolio
seeking stability of principal,  such as a money market portfolio or a portfolio
investing  primarily in obligations issued or guaranteed by the U.S.  government
or its agencies or instrumentalities  (these obligations are referred to in this
Prospectus as "U.S. government  securities").  To maximize potential return, the
Adviser may utilize a variety of investment  techniques and strategies including
but not limited to:  writing  listed  "covered"  call and "secured" put options,
including options on stock indices, and purchasing such options;  purchasing and
selling,  for hedging  purposes,  stock index,  interest rate, and other futures
contracts, and purchasing options on such futures contracts; purchasing warrants
and preferred and convertible preferred stocks; borrowing from banks to purchase
securities;  purchasing  foreign  securities in the form of American  Depository
Receipts;  purchasing  securities of other investment  companies;  entering into
repurchase   agreements;   purchasing   restricted   securities;   investing  in
when-issued  or  delayed  delivery  securities;  and  selling  securities  short
"against the box." See "Description of Securities and Investment  Techniques" in
the SAI for further  information.  The Common Stock Portfolio may also invest in
high yield,  high risk,  lower-rated  debt  securities,  commonly known as "junk
bonds".  Investments in high yield,  high risk debt  securities  involve certain
risks, as discussed with respect to the Asset  Allocation  Portfolio  below. See
"Risks  Associated  With High  Yield  Debt  Securities"  in the SAI for  further
information.
    
ASSET ALLOCATION PORTFOLIO
         The investment objective of the Asset Allocation Portfolio is to seek a
high total  investment  return  consistent with the  preservation of capital and
prudent  investment  risk.  The  Portfolio  seeks to achieve  this  objective by
pursuing an active asset allocation  strategy whereby  investments are allocated
based upon thorough investment research, valuation and analysis of market trends
and the anticipated relative total return available among various asset classes,
including debt securities, equity securities and money market instruments. Total
investment return consists of current income, including dividends, interest, and
discount accruals, and capital appreciation. Achieving this objective depends on
the  Adviser's  ability to assess the effect of  economic  and market  trends on
different sectors of the market. In seeking to maximize total return,  the Asset
Allocation  Portfolio  will follow an asset  allocation  strategy  contemplating
shifts  (which may be  frequent)  among a wide range of  investments  and market
sectors.  The Portfolio's  investments will be designed to maximize total return
during all economic and financial environments,  consistent with prudent risk as
determined by the Adviser.


         The  Asset  Allocation   Portfolio  will  invest  in  U.S.   government
securities,  intermediate and long-term debt securities and equity securities of
domestic and foreign issuers, including common and preferred stocks, convertible
debt securities,  and warrants.  If the Adviser deems stock market conditions to
be  favorable  or debt market  conditions  to be  uncertain  or  unfavorable,  a
substantially  higher percentage of the Portfolio's total assets may be invested
in  equity  securities.  If,  however,  the  Adviser  believes  that the  equity
environment  is  uncertain  or  unfavorable,  the  Portfolio  may  decrease  its
investments  in  equity   securities  and  increase  its   investments  in  debt
securities.  Furthermore,  if the Adviser believes that inflationary or monetary
conditions  warrant a significant  investment in companies  involved in precious
metals,  the  Portfolio  may invest up to 10 percent of its total  assets in the
equity securities of companies  exploring,  mining,  developing,  producing,  or
distributing gold or other precious metals.  Additionally,  the Asset Allocation
Portfolio  may  make  temporary   defensive   investments  (i.e.,  money  market
instruments)  without limit if it is believed that market  conditions  warrant a
more conservative investment strategy.

         The Asset Allocation  Portfolio may use various  investment  strategies
and techniques  when the Adviser  determines  that such use is appropriate in an
effort to meet the Portfolio's  investment objective,  including but not limited
to: writing listed "covered" call and "secured" put options,  including  options
on stock indices,  and

                                                                   PROSPECTUS

purchasing such options;  purchasing and selling,  for hedging  purposes,  stock
index, interest rate, gold, and other futures contracts,  and purchasing options
on such futures  contracts;  purchasing  warrants and preferred and  convertible
preferred stocks; purchasing foreign securities;  entering into foreign currency
transactions and options on foreign currencies; borrowing from banks to purchase
securities;  purchasing securities of other investment companies;  entering into
repurchase   agreements;   purchasing   restricted   securities;   investing  in
when-issued  or  delayed  delivery  securities;  and  selling  securities  short
"against the box." See "Description of Securities and Investment  Techniques" in
the SAI for further information.

         The maturities of the debt securities in the Asset Allocation Portfolio
will vary based in large part on the Adviser's expectations as to future changes
in interest rates.  However,  the Adviser anticipates that the debt component of
the  Portfolio  will  generally  be  invested  primarily  in  intermediate  debt
securities,  and/or long-term debt securities.  The Adviser anticipates that the
equity portion of the Portfolio will be widely  diversified by both industry and
number of issuers.  The Adviser's stock selection  methods will be based in part
upon  variables  which it  believes  significantly  relate to the future  market
performance  of a stock,  such as recent changes in earnings per share and their
deviations from analysts'  expectations,  past growth trends,  price movement of
the stock itself,  publicly recorded trading transactions by corporate insiders,
and relative  price-earnings  ratios.  The Adviser  anticipates  that investment
opportunities  will often be sought  among  securities  of  larger,  established
companies, although securities of smaller, less well-known companies may also be
selected. Small company stock are subject to the risks described with respect to
the Common Stock Portfolio.

         The Asset  Allocation  Portfolio  may also invest in high  yield,  high
risk, lower-rated debt securities,  which are not believed to involve undue risk
to income or principal.  Generally, higher yielding bonds carry ratings assigned
by Moody's Investors Service, Inc. ("Moody's") or Standard & Poor's ("S&P") that
are lower than those assigned to investment grade debt  securities,  or they are
unrated.  Lower rated debt securities and unrated  securities  determined by the
Adviser  to  be  below  investment  grade  carry  higher  investment  risk  than
investment  grade debt securities.  The market values of lower-rated  securities
generally  fluctuate  more  widely  than those of  higher-rated  securities.  In
addition, changes in economic conditions or other circumstances, such as changes
in the financial  condition of issuers or in interest rates,  are more likely to
lead to a weakened  capacity for such  securities to make principal and interest
payments  than is generally  the case for higher grade debt  securities.  To the
extent that there is no established  retail secondary market,  there may be thin
trading of high yield,  lower-rated debt  securities,  and this may make it more
difficult to accurately  value the  lower-rated  debt  securities and the Fund's
assets, and to dispose of such securities. The lowest rating categories in which
the  Portfolio  will invest are  CCC/Caa.  Securities  in these  categories  are
considered  to be of  poor  standing  and  are  predominantly  speculative.  See
"Appendix A" to this  Prospectus  for further  discussion  regarding  securities
ratings  and  "Risks   Associated  With  High  Yield  Debt   Securities"   under
"Description of Securities and Investment Techniques" in the SAI.

         The  Asset  Allocation   Portfolio  may  also  invest  in  zero  coupon
securities  and  payment-in-kind  securities.  A zero  coupon  security  pays no
interest to its holders  prior to maturity and a  payment-in-kind  security pays
interest in the form of additional securities.  These securities will be subject
to greater  fluctuation  in market value in response to changing  interest rates
than securities of comparable  maturities that make periodic cash  distributions
of interest.

         The Asset  Allocation  Portfolio  may also  invest  in equity  and debt
securities of foreign issuers, including non-U.S. dollar-denominated securities,
Eurodollar  securities and securities  issued,  assumed or guaranteed by foreign
governments  or  political  subdivisions  or  instrumentalities  thereof.  As  a
non-fundamental operating policy, the Asset Allocation Portfolio will not invest
more than 50 percent of its total assets (measured at the time of investment) in
foreign  securities.  Investments in foreign  securities  involve certain risks,
including fluctuations in foreign exchange rates, and the possible imposition of
exchange controls or other foreign  governmental  laws or restrictions.  Foreign
companies may not be subject to accounting,  auditing,  and financial  reporting
standards and requirements  comparable to those to which the U.S. is subject. In
addition,  with  respect  to  certain  countries,  there is the  possibility  of
expropriation of assets, confiscatory taxation, political or social instability,
or diplomatic  developments  that could  adversely  affect  investments in those
countries.  See  "Foreign  Securities"  under  "Description  of  Securities  and

GOVERNMENT SECURITIES PORTFOLIO
         In seeking its  objective of safety of capital,  liquidity  and current
income, the Government  Securities Portfolio will invest primarily in securities
issued  by the U.S.  government  or an  agency  or  instrumentality  of the U.S.
government,   including   mortgage-related   securities.   The  U.S.  government
securities which may be purchased by the Government Securities Portfolio include
direct obligations issued by the United States Treasury, such as Treasury bills,
certificates  of  indebtedness,  notes  and  bonds.  The  Government  Securities
Portfolio  may also  purchase  instruments  issued or  guaranteed by agencies or
instrumentalities  of the United States government,  including  mortgage-related
securities.

         Among the  mortgage-related  securities  that may be  purchased  by the
Government   Securities  Portfolio  are  "mortgage-backed   securities"  of  the
Government  National  Mortgage  Association  ("GNMA"),  the  Federal  Home  Loan
Mortgage  Corporation  ("FHLMC") and the Federal National  Mortgage  Association
("FNMA"). These mortgage-backed securities include "pass-through" securities and
"participation  certificates," both of which are similar,  representing pools of
mortgages  that are assembled,  with  interests  sold in each pool.  Payments of
principal  (including  prepayments)  and interest by individual  mortgagors  are
"passed  through"  to the  holders of the  interests  in each pool;  thus,  each
payment to holders  may  contain  varying  amounts of  principal  and  interest.
Another  type  of  mortgage-backed  security  is  the  "collateralized  mortgage
obligation."  Collateralized  mortgage  obligations  are similar to conventional
bonds in that they have fixed  maturities  and interest rates but are secured by
groups of individual mortgages. Timely payment of principal and interest on GNMA
pass-throughs  is guaranteed by the full faith and credit of the United  States.
FHLMC  and FNMA are both  instrumentalities  of the U.S.  government,  but their
obligations  are not backed by the full  faith and credit of the United  States.
Mortgage pass-through securities or modified pass-through securities are subject
to early  repayment of principal  arising from  prepayments  of principal on the
underlying  mortgage loans.  Prepayment rates vary widely and may be affected by
changes  in  market  interest  rates  and  other  economic  trends  or  factors.
Accordingly,  it is not  possible to  accurately  predict the average  life of a
particular  underlying pool of mortgages.  Reinvestment of prepayments may occur
at a higher or lower rate than the original yield on the securities.  Therefore,
the actual maturity and realized yield on pass-through or modified  pass-through
mortgage-backed securities will vary based upon the prepayment experience of the
underlying  pool.  See   "Mortgage-Backed   Securities"  under  "Description  of
Securities and Investment Techniques" in the SAI for further information.
    
         Also included within the term "U.S. government securities" are deposits
in banks to the extent  that such  deposits  (including  accrued  interest)  are
federally insured ("Insured  Deposits").  Such insurance is currently limited to
$100,000  per bank.  The  Government  Securities  Portfolio  will not permit any
Insured Deposit, including any interest thereon, to exceed the insured amount.
Insured Deposits may have limited marketability.

         The  Government  Securities  Portfolio  may  purchase  mortgage-related
securities  not issued by the U.S.  government or any agency or  instrumentality
thereof. The Government Securities Portfolio may also invest in investment grade
corporate debt securities.  Debt securities purchased by the Portfolio may be of
any maturity.  It is anticipated  that the weighted average maturity of the debt
portfolio  generally  will be between  four and 15 years,  but may be shorter or
longer  under  unusual  market  circumstances.  That  portion of the  investment
Portfolio which is not invested in U.S.  government  securities will be invested
in high rated debt  securities  that the  Adviser  believes  will not expose the
Portfolio  to undue  risk.  While  non-U.S.  government  securities  may present
greater credit risk than U.S.  government  securities,  they also tend to afford
higher yields than U.S. government securities.

         The  Government   Securities   Portfolio  may  use  various  investment
strategies  and  techniques  when  the  Adviser  determines  that  such  use  is
appropriate  in an effort to meet the  Portfolio's  investment  objective.  Such
strategies  and  techniques  include,  but are not  limited to,  writing  listed
"covered" call and "secured" put options and purchasing such options; purchasing
and selling,  for hedging purposes,  interest rate and other futures  contracts,
and  purchasing  options  on such  futures  contracts;  borrowing  from banks to
purchase  securities;  investing in  securities of other  investment  companies;
entering  into  repurchase  agreements;  investing  in  when-issued  or  delayed
delivery  securities;  and  selling  securities  short  "against  the  box." See

         There is minimal  credit risk involved in the purchase of government or
government-guaranteed  securities. However, as with any fixed income investment,
when interest rates decline,  the market value of a portfolio invested at higher
yields can be expected to rise. Conversely, when interest rates rise, the market
value of a  portfolio  invested  at lower  yields can be  expected  to  decline.
Therefore, the Trust may engage in portfolio trading to take advantage of market
developments and yield disparities, for example, shortening the average maturity
of the Portfolio in  anticipation  of a rise in interest rates so as to minimize
depreciation of principal,  or lengthening the average maturity of the Portfolio
in anticipation of a decline in interest rates so as to maximize appreciation of
principal.  However,  the Adviser  does not pursue  interest  rate  anticipation
strategies within its style of investment management.

CORPORATE BOND PORTFOLIO
         In seeking its  investment  objective of providing the highest level of
income as is consistent  with the  preservation  of capital,  the Corporate Bond
Portfolio  invests  primarily in investment  grade debt  securities,  as defined
below.  The Adviser  seeks to reduce  risk,  increase  income,  and  preserve or
enhance  total  return by actively  managing  the  Portfolio  in light of market
conditions  and trends.  The Adviser seeks to enhance total return  specifically
through  purchasing  securities  which the Adviser  believes are undervalued and
selling, when appropriate, those securities the Adviser believes are overvalued.
In order to  determine  value,  the  Adviser  utilizes  independent  fundamental
analysis of the issuer as well as an analysis of the  specific  structure of the
security.  A debt security will be considered  "investment grade" if it is rated
in one of  the  four  highest  rating  categories  by at  least  one  nationally
recognized  statistical  rating  organization  ("NRSRO"),  or, in the case of an
unrated  security,  if the Adviser  determines  such  security is of  comparable
quality to securities  rated in one of the four highest rating  categories.  The
Corporate  Bond Portfolio may invest in debt  securities  issued by publicly and
privately held U.S. and foreign companies,  the U.S. government and agencies and
instrumentalities thereof, states and their political subdivisions, agencies and
instrumentalities  ("municipal  securities")  and foreign  governments and their
agencies and  instrumentalities.  The interest on municipal  securities in which
the  Portfolio  invests  typically  is  not  exempt  from  federal  income  tax.
Investments in foreign securities involve certain risks,  discussed with respect
to the Asset Allocation  Portfolio.  See "Foreign Securities" under "Description
of Securities and Investment Techniques" in the SAI for further information. The
Corporate Bond Portfolio may also invest in  mortgage-related  debt  securities,
other types of asset-backed debt securities, and other forms of debt securities.
Mortgage-related debt securities are subject to certain risks, as discussed with
respect to the Government  Securities  Portfolio above. For further information,
see "Debt Securities" and "Mortgage-backed  Securities" in the SAI. In addition,
up to 15 percent of the  Portfolio's  assets may be invested  directly in equity
securities,  including preferred and common stocks,  convertible debt securities
and debt securities  carrying warrants to purchase equity securities,  and up to
10 percent of the Portfolio's  assets may be invested in debt  securities  below
investment grade.
   
         Debt securities purchased by the Corporate Bond Portfolio may be of any
maturity. It is anticipated that the weighted average life of the debt portfolio
will be between  seven and 15 years,  but may be shorter or longer  depending on
market conditions. While the Corporate Bond Portfolio intends to invest in fixed
income securities in order to achieve its investment  objective of obtaining the
highest level of income  consistent with  preservation  of capital,  it may from
time to time  invest in fixed  income  securities  which  offer  higher  capital
appreciation potential. Such investments would be in addition to that portion of
the  Portfolio  which may be invested in common stocks and other types of equity
securities.
    
         With respect to the Portfolio's  investment in fixed income securities,
such  securities  will be affected by changes in interest  rates.  When interest
rates decline,  the market value of a portfolio invested at higher yields can be
expected to rise.  Conversely,  when interest  rates rise, the market value of a
portfolio  invested at lower yields can be expected to decline.  Therefore,  the
Portfolio  may  engage  in  portfolio   trading  to  take  advantage  of  market
developments and yield disparities; for example, shortening the average maturity
of the Portfolio in  anticipation  of a rise in interest rates so as to minimize
depreciation of principal,  or lengthening the average maturity of the Portfolio
in anticipation of a decline in interest rates so as to maximize appreciation of
principal.  However,  the Adviser  does not pursue  interest  rate

anticipation strategies within its style of investment management.

         The Corporate Bond Portfolio may use various investment  strategies and
techniques when the Adviser determines that such use is appropriate in an effort
to meet the  Portfolio's  investment  objective.  Such strategies and techniques
include, but are not limited to, writing listed "covered" call and "secured" put
options  and  purchasing  such  options;  purchasing  and  selling,  for hedging
purposes,  interest rate and other futures contracts,  and purchasing options on
such futures contracts;  borrowing from banks to purchase securities;  investing
in  securities  of  other   investment   companies;   entering  into  repurchase
agreements; investing in when-issued or delayed delivery securities; and selling
securities   short  "against  the  box."  See  "Description  of  Securities  and
Investment Techniques" in the SAI for further information.

Money Market Portfolio
         In seeking its objective of current income consistent with stability of
capital  and  liquidity,  the Money  Market  Portfolio  may  invest  only in the
following kinds of money market securities:

(1)      U.S.  GOVERNMENT  SECURITIES:  Obligations  issued or guaranteed by the
         U.S. government or its agencies or instrumentalities;

(2)      BANK  OBLIGATIONS:  Time deposits,  certificates  of deposit,  bankers'
         acceptances and other bank obligations if they are obligations of banks
         having  total  assets in  excess  of $1  billion  that are  subject  to
         regulation by the U.S. government,  including (i) U.S.  subsidiaries of
         foreign  banks,  (ii)  London  branches of  domestic  banks,  and (iii)
         foreign branches of domestic commercial banks and foreign banks so long
         as  the  securities  are  U.S.  dollar-denominated.  There  can  be  no
         assurance that, in the future,  exchange  control or other  regulations
         might not be  adopted  which  would  adversely  affect  the  payment of
         principal  and  interest  on the  obligations  of foreign  branches  of
         domestic  commercial banks and foreign banks (See "Foreign  Securities"
         and  "Banking   Industry  and  Savings  Industry   Obligations"   under
         "Description  of Securities and  Investment  Techniques" in the SAI for
         further  information,  and  note  that in  this  Prospectus,  a  "bank"
         includes   commercial  banks,   savings  banks  and  savings  and  loan
         associations);

(3)      COMMERCIAL PAPER OBLIGATIONS:  Commercial paper, including variable and
         floating rate securities of U.S. corporations,  rated A-1 or A-2 by S&P
         or Prime-1 or Prime-2  by  Moody's  or, if not rated,  of a  comparable
         quality as determined by the Adviser under  supervision of the Board of
         Trustees  as  described   below  (See   "Variable   and  Floating  Rate
         Securities" under "Description of Securities and Investment Techniques"
         in the SAI for further information and see Appendix A for a description
         of the securities ratings); and

(4)      SHORT-TERM CORPORATE DEBT SECURITIES:  Corporate debt securities (other
         than commercial paper) maturing in 13 months or less.

         Money Market  instruments  are generally  described as short-term  debt
obligations  having  maturities of 13 months or less. Yields on such instruments
are very sensitive to short-term lending conditions. The principal value of such
instruments tends to decline as interest rates rise and conversely tends to rise
as interest  rates  decline.  In addition,  there is an element of risk in money
market  instruments that the issuer may become insolvent and may not make timely
payment of interest and principal obligations.

         The Money Market  Portfolio may invest only in U.S.  dollar-denominated
money market instruments that present "minimal credit risk." At least 95 percent
of the  Money  Market  Portfolio's  total  assets,  as  measured  at the time of
investment,  must be of the  "highest  quality."  The  Adviser  shall  determine
whether a security presents minimal credit risk under procedures  adopted by the
Board of Trustees.  A money market  instrument  will be  considered to be of the
highest quality (1) if it is rated in the highest rating category by (i) any two
NRSROs or, (ii) by the only NRSRO that rated the  security;  (2) if, in the case
of an  instrument  with a  remaining  maturity  of 13  months  or less  that was
long-term  at the time of  issuance,  the issuer  thereof  has  short-term  debt
obligations  comparable in priority and security to such security,  and that are
rated in the  highest  rating  category  by (i) any two NRSROs or, (ii) the only
NRSRO that has rated the  security;  or (3) in the case of an unrated  security,
such  security is of  comparable  quality to a security  in the  highest  rating
category as determined by the Adviser.  At

                                                                     1998

                                                                   PROSPECTUS

present, current procedures require that the acquisition of such securities that
are  unrated or are rated by only one NRSRO be approved or ratified by the Board
of  Trustees;  however,  as is  permitted  by current  regulation,  the Board of
Trustees may choose to eliminate this  procedural  requirement  concerning  such
securities. With respect to no more than 5 percent of its total assets, measured
at the time of  investment,  the  Portfolio  may  also  invest  in money  market
instruments that are in the  second-highest  rating category for short-term debt
obligations.  A  money  market  instrument  will  be  considered  to be  in  the
second-highest   rating  category  under  the  procedures  described  above  for
determining  whether an instrument is considered highest quality,  as applied to
instruments in the second-highest rating category.

         The Money  Market  Portfolio  may not invest more than 5 percent of its
total  assets,  measured at the time of  investment,  in  securities  of any one
issuer,  except  that  this  limitation  shall  not  apply  to  U.S.  government
securities and repurchase  agreements  thereon and except that the Portfolio may
invest more than 5 percent of its total assets in  securities of a single issuer
that are of the highest  quality for a period of up to three  business days. The
Portfolio  may not invest more than the greater of 1 percent of its total assets
or  $1,000,000,  measured at the time of  investment,  in  securities of any one
issuer  that  are  in the  second-highest  rating  category,  except  that  this
limitation shall not apply to U.S. government  securities.  In the event that an
instrument  acquired by the Money Market  Portfolio is  downgraded  or otherwise
ceases to be of the quality  that is eligible  for the  Portfolio,  the Adviser,
under  procedures  approved by the Board of Trustees,  shall promptly  re-assess
whether such security  presents minimal credit risk and determine whether or not
to retain the instrument.

         From time to time, the Money Market  Portfolio may purchase  securities
on a when-issued or delayed  delivery  basis.  The Portfolio may also enter into
repurchase agreements. See "Description of Securities and Investment Techniques"
in the SAI for further information.

         The  Money  Market  Portfolio  uses  the  "amortized  cost"  method  of
valuation  and  seeks to  maintain  a net  asset  value of $1.00  per  share for
purposes of purchases and redemptions;  however, an investment in this Portfolio
is neither  insured nor guaranteed by the U.S.  government,  and there can be no
assurance  that the Portfolio will be able to maintain a stable net asset value.
The Portfolio will be affected by general changes in interest rates resulting in
increases or decreases in the value of the obligations held by the Portfolio.


MANAGEMENT
         The Trustees of the Trust decide upon matters of general policy for the
Trust. In addition,  the Trustees review the actions of the Trust's Adviser,  as
set forth below. The Trust's officers supervise the daily business operations of
the Trust.

         Conseco Capital Management, Inc. (the "Adviser"), 11825 N. Pennsylvania
Street,  Carmel,  Indiana  46032,  has been retained under  Investment  Advisory
Agreements  with the Trust,  to  provide  investment  advice,  and in general to
supervise the management and investment program of the Trust and each Portfolio.
In addition,  the Adviser generally manages the affairs of the Trust, subject to
the  supervision of the Board of Trustees.  For  information  about the Board of
Trustees  and the  Trust's  officers,  see  "Management"  in the SAI.  Under the
Investment  Advisory  Agreements,  the  Adviser  has  contracted  to  receive an
investment  advisory  fee equal to an annual rate of 0.25 percent of the average
daily net asset value of the Money Market Portfolio, 0.50 percent of the average
daily  net  asset  value  of  the  Government   Securities  and  Corporate  Bond
Portfolios,  0.60  percent of the  average  daily net asset  value of the Common
Stock  Portfolio,  and 0.55 percent of the average  daily net asset value of the
Asset Allocation Portfolio.  The Adviser also manages all of the invested assets
of its  parent  company,  Conseco,  Inc.,  which owns or  manages  several  life
insurance  subsidiaries,  and provides investment and servicing functions to the
Conseco companies and affiliates. The Adviser also provides investment advice to
Conseco Fund Group, a registered  open-end management  investment  company.  The
Adviser  has  been  the  investment  adviser  to the  Trust  since  the  Trust's
inception. The Adviser has agreed that the ratio of expenses to net assets on an
annual basis for the Common Stock Portfolio  shall not exceed 0.80 percent,  the
Asset  Allocation  Portfolio  shall not  exceed  0.75  percent,  the  Government
Securities and the Corporate Bond Portfolios shall not exceed 0.70 percent,  and
the Money Market  Portfolio  shall not exceed 0.45 percent.  For the years ended
December 31, 1997,  1996,  and 1995,  the  Adviser's  fees before  reimbursement
totaled  $1,400,378,  $1,008,557,  and  $695,347,  respectively,  which was 0.58
percent,  0.58 percent,  and 0.57  percent,  of the average net 

                                       17

assets for 1997,  1996,  and 1995  respectively.  Total  expenses of the average
annual net assets of each  Portfolio  for the years ended  1997,  1996 and 1995;
were as follows:  Common Stock, 0.80 percent;  Asset  Allocation,  0.75 percent;
Government Securities, 0.70 percent; Corporate Bond, 0.70 percent; Money Market,
0.45 percent.

         The investment  professionals  primarily responsible for the management
of each Portfolio, with the respective  responsibilities and business experience
for the past five years are as follows:

         COMMON STOCK:  Thomas J. Pence,  Vice President for the Adviser.  He is
responsible for the management of the Adviser's equity  portfolios and oversight
of the equity investment process. Prior to joining the Adviser, Mr. Pence worked
for five years as a securities  analyst in the field of real estate  acquisition
and  development  in  which  he  specialized  in  residential   development  and
construction  finance and was responsible for overseeing a project  portfolio of
$750 million in real estate assets.

         ASSET  ALLOCATION:  Gregory  J.  Hahn,  Portfolio  Manager of the fixed
income portion of the Portfolio and Senior Vice President,  Portfolio  Analytics
for the Adviser.  He is responsible for the portfolio analysis and management of
the tax-exempt  client  accounts and analytical  support and systems support for
taxable  portfolios.  In  addition,  he has  responsibility  for the  registered
products as well as investments in the insurance industry.

         Prior to joining the  Adviser,  Mr. Hahn was a fixed  income  portfolio
manager for Unified  Management,  Inc.,  where he was  responsible for over $700
million in money market,  municipal,  and corporate bond mutual funds. Among the
funds Mr. Hahn was  responsible  for were the Liquid  Green Trust and the highly
rated Liquid Green Tax Free Trust. Before joining Unified, he was a fixed income
portfolio manager and municipal bond trader for Indiana National Bank.

         Thomas  J.  Pence,  Portfolio  Manager  of the  equity  portion  of the
Portfolio. See Mr. Pence's business experience above.
   
         GOVERNMENT SECURITIES:  G. Nolan Smith, Vice President for the Adviser.
He is responsible for taxable and tax-exempt fixed income portfolio  management.
Mr.  Smith was  previously  employed by Strong  Capital  Management.  During his
tenure,  he managed the Strong Municipal Money Market,  Short-Term and Municipal
Bond Funds.  Prior to joining Strong Capital  Management,  Mr. Smith was a fixed
income credit analyst at USAA Investment Management Company.
    
         CORPORATE  BOND:  Gregory J. Hahn. See Mr. Hahn's  business  experience
above.
         MONEY MARKET:  Darren Meyer,  Trader for the Adviser. He is responsible
for money market  trading for the  Adviser.  Mr. Meyer has been a trader for the
Adviser  since  1994.  He  was  previously  employed  by  the  Adviser's  parent
corporation in its accounting department since 1992.

         Like other  financial  and business  organizations,  the Trust could be
adversely  affected if computer  systems  they rely on do not  properly  process
date-related  information  and data  involving  the years  2000 and  after.  The
Adviser is taking steps that it believes are  reasonable to address this problem
in its own computer  systems and to obtain  assurances that comparable steps are
being  taken by the Funds'  other major  service  providers.  The  Adviser  also
attempts  to evaluate  the  potential  impact of this  problem on the issuers of
investment  securities  that  the  Funds  purchase.  However,  there  can  be no
assurance that these steps will be sufficient to avoid any adverse impact on the
Funds.

MANAGEMENT DISCUSSION AND ANALYSIS
   
COMMON STOCK PORTFOLIO
         As we look back at 1997,  we are able to draw a few insights on what is
in store for 1998.  While the first three quarters  exhibited  strong growth and
favorable  market  conditions,  the fourth quarter proved to be most eventful in
terms of future effects on market performances.
    
         As is typical  for most  fourth  quarters,  the period  began with much
anxiety related to market strength,  sustainability  of corporate  profits,  and
increasing  volatility in Asian currency  markets.  Anxieties  peaked on October
27th when the Dow Jones Industrial Average dropped 554 points (7.2 percent), the
largest single point decline ever, surrounding fears of asset deflation in Asian
markets.  Despite a  relatively  good  series of earnings  reports and  economic
releases  throughout  the balance of the quarter,  including  low  inflation and
25-year-low unemployment levels, concerns about the Asian influence prevailed.

         Following the market plunge, much of the capital previously invested in
Asia-Pacific  markets sought safety in the U.S. market through  purchases of S&P
500 futures contracts.  As a result, the Index gained ground, with stocks of the
largest 20 companies  in the  marketplace  outperforming  nearly  everything  in
sight.  However,  virtually all other stocks  remained at October 27th levels or
drifted even lower. Due to the strong fourth quarter move of the largest company
stocks,  the S&P 500  finished  the year up  33.36  percent,  outperforming  the
returns of 90 percent of all  actively  managed  funds,  as well as the  Russell
Small Stock Index,  which returned 22.36  percent.  This is the fourth  straight
year that the market has seen this kind of divergence.

         In terms  of  sector  performance,  strong  returns  were  realized  in
interest  rate-sensitive  areas  (financial  institutions  and utilities) and in
defensive stocks (food retailers and consumer staples).  These sectors benefited
from the strong rally in the bond market and from the influx of invested dollars
coming from  technology and energy  sectors,  which turned in some of the fourth
quarter's  lowest  returns.   Our  underweighting  in  financial   institutions,
utilities and staples and our larger weightings in technology and energy explain
why the fourth quarter was a difficult one for us.

         Despite  these  problems,  many of our  stocks  enjoyed  good  earnings
reports and  persevered  during a time of high market  volatility.  Perhaps most
rewarding was the  announcement  that IBM/Trivoli  bought Software  Artistry for
$24.50 per share cash; we were  prematurely  rewarded with a 200 percent  return
for our share owners over the holding period.

         We expect a  cautionary  tone to prevail  over the  market in 1998;  as
such,  we intend to increase our focus on earnings  stories with strong  balance
sheets and  cashflow  generation.  We will also look for yield as a component of
total return whenever possible.  In addition, we will watch for opportunities in
technology  and energy given the  aggressive  sell-off in these  sectors in late
1997.

         Our investment  strategy  continues to rely on a bottom-up  approach to
stock selection. Through extensive research of the companies in which we invest,
our goal is to  discover  good  growth  stories in stocks  that  still  trade at
reasonable  valuations.  We  are  committed  to a  long-term  reliance  on  this
strategy,  and believe  that it will serve our share owners well in the upcoming
year.

ASSET ALLOCATION PORTFOLIO
         The Asset  Allocation  Fund is a balanced  portfolio which invests in a
combination  of  equity,  fixed  income  and  cash.  The  strategy  of the Asset
Allocation  Fund  through  1997 has been to highlight  equity  securities  which
represented roughly 55 percent of the portfolio's assets.

         The fourth  quarter  began with much anxiety  about the strength in the
market  over  the  summer,  the  sustainability  of  corporate  profits  and the
increasing volatility of Asian currency markets. All fears reached a fever pitch
on October 27th when the Dow Jones  Industrial  Average  dropped 554 points (7.2
percent),  recording  the largest  single  point  decline ever on fears of asset
deflation in Asian markets. The performance of the market following the sell-off
was  typical  of  what  we saw  earlier  in the  year,  with  the  index  stocks
outperforming  the broader  market as hoards of capital  previously  invested in
Asia-Pacific  markets  sought safe haven in the U.S.  market.  The result of all
this was that the Index gained while virtually everything else stayed at October
27th levels or drifted even lower. In fact, because of its strong fourth quarter
move  relative  to the  broader  market,  the  Standard & Poor's 500 ("S&P 500")
finished the year up 33.36  percent,  outstripping  the returns of 90 percent of
all actively managed funds and the Russell 2000 Small Stock Index which returned
22.36 percent.  This is the fourth  straight year that we have seen this kind of
divergence.

         Going forward, with respect to the equity portion of the portfolio,  we
intend to continue  our  strategy of  utilizing a bottom-up  approach in finding
good  growth  stories in stocks that still trade at  reasonable  valuations.  In
fact,  if 1998  earnings  on S&P 500  companies  ultimately  end up in line with
current expectations of 7 to 9 percent,  then we would expect to see an increase
in  multiples  for stocks  which can  generate  earnings  growth in the 18 to 20
percent range.

         The remaining 45 percent of the Asset Allocation  Portfolio is invested
in bonds and cash.  Our fixed  income  discipline  focuses on investing in those
securities  which,  through  our own  fundamental  research,  we  consider to be
undervalued.  Depending  on  valuation  in the  equity  market,  we may take the
opportunity  to  reallocate a portion of the portfolio to fixed income if we see
pressure on earnings or negative earnings surprises.  Until the financial crisis
in Asia  subsides,  we expect to see  sustained  low levels of  interest  rates.
Eventually,  as investors return their focus to economic fundamentals,  we still
expect  to see  interest  rates  remain  low,  which  should  bode  well for the
valuation of financial assets.

GOVERNMENT SECURITIES PORTFOLIO
         The currency crisis in Asia has pulled the U.S. Government along in its
torrent.  The  unprecedented  drop in yields has apparently  little regard for a
U.S.  economy  that is  operating  at capacity  with a tight labor  market.  The
Federal  Reserve has continued its policy of benign  neglect in part due to good
news on the inflation front.

         The "Asian contagion" has not been without its peripheral  symptoms for
the  seemingly  immune bond  market.  Corporate  bond  spreads  have  widened in
response  to a fuzzy  profit  picture  and  U.S.  Government  Agency  securities
("Agency")  have followed suit, if only to keep pace with  corporates.  Thus, we
have been utilizing  both  corporates and Agency spreads in the short portion of
the portfolio to increase the overall yield of the portfolio  without  incurring
significant risk. In addition, as Agency spreads have widened significantly,  we
have taken advantage of this opportunity to purchase  various Agency  securities
in the  shorter  maturity  spectrum.  The  outlook for the early part of 1998 is
clouded  by  events in Asia,  but we  believe  most of the  drama is behind  us.
Restructuring will be time consuming and painful for the Asian populace,  and we
doubt if the U.S.  Government  bond market will be able to sustain these levels.
Consequently,  the  Portfolio is shorter in duration  than our  benchmark and we
have taken  advantage  of the  widening  in spread to increase  the  Portfolio's
position in corporate and Agency securities.

CORPORATE BOND PORTFOLIO
         1997 was characterized by favorable market  conditions  throughout much
of the year. However, increased volatility brought dramatic changes to the fixed
income markets, especially in the fourth quarter.

         The  first  three  quarters  of 1997  were  distinguished  by a strong,
healthy  economy,  low  inflation  levels and a general  trend toward  declining
interest  rates.  Relative  value in the fixed income  markets was  difficult to
distinguish  as spreads to  treasuries  remained  very  narrow in many  sectors,
including corporate and mortgage-backed  securities.  Investors typically demand
larger  spreads over U.S.  Treasury  bonds in order to compensate  for perceived
higher risk  levels.  Federal  Reserve  policy  stayed  tight as Alan  Greenspan
remained the vigilant  watchdog over inflation.  The budget deficit continued to
narrow as a result of lower interest rates and fiscal  discipline from Congress.
However,  the focus of the  financial  markets  shifted  away from the  domestic
economic fundamentals in the fourth quarter.

         In the fourth quarter, currency deterioration in Thailand, Malaysia and
Indonesia,  caused turmoil in their respective  financial  markets.  Because the
world's  economies  are  linked,  the  impact  of this  turmoil  spread  quickly
throughout  Southeast Asia. As we move into 1998, the crisis is expected to have
a significant impact on economic growth in other countries, including the United
States.  This  phenomenon  has already  caused  dramatic  changes in the general
fundamentals  of our domestic fixed income market,  which created  significantly
larger spreads to U.S. Treasures in the corporate sector.

         The level of interest rates declined  because of the financial  crisis:
the  ten-year  U.S.  Treasury  yield  was  5.75  percent  at  year-end  and  the
thirty-year U.S. Treasury yield was 5.92 percent.  With this dramatic decline in
interest rates, we have maintained a low exposure to mortgage-backed securities,
due  to  the  higher  risk  of  increased  pre-payment  activity.   With  higher
pre-payments,  the  security  returns  more  principal,  forcing the investor to
reinvest the proceeds at lower interest rates.

         Nolan Smith, our municipal bond specialist,  continues to recommend the
taxable municipal sector due to consistent spreads over U.S.  Treasuries,  which
have performed better than the corporate sector. We expect to direct proceeds to
this sector,  given its performance  relative to the rest of the market. At this
point, we have  discovered  only a few bonds meeting our investment  criteria of
offering good relative value.

         Our fixed income investment  strategy continues to emphasize  investing
in those securities we believe are  undervalued.  Most  importantly,  we conduct
thorough  research before  investing in any security.  Our long-term  strategies
coupled with our extensive  knowledge of each  investment we select enable us to
look forward with confidence as we continue to invest for the future.

PURCHASE AND REDEMPTION OF SHARES
         Bankers  National and Great  American  Reserve are the sponsors for the
separate accounts that are funding the Trust's shares.  Shares of each Portfolio
are  purchased or redeemed at their  respective  net asset values next  computed
(without a sales charge) after receipt of an order as required by the 1940 Act.

         The net asset value of shares of each  Portfolio is  determined on each
Monday through Friday,  except customary national business holidays on which the
New York Stock Exchange is not open for trading, and days during which no shares
of the Portfolio  were tendered for  redemption and no order to purchase or sell
such shares was  received.  The net asset value of shares for each  Portfolio is
determined  by adding up the value of its  securities  (determined  as set forth
below) and other assets, subtracting the liabilities, and dividing by the number
of shares  outstanding.  The valuations of each Portfolio are based on the close
of regular trading on the New York Stock Exchange  (normally  4:00p.m.,  Eastern
time).

         The Board of Trustees  has  determined  that the best method  currently
available  for valuing  the  securities  of the Money  Market  Portfolio  is the
amortized cost method. This method values a security at the time of its purchase
at cost and  thereafter  assumes a  constant  amortization  to  maturity  of any
discount or premium,  regardless of the impact of fluctuating  interest rates on
the  market  value of the  security.  This  method  does not take  into  account
unrealized gains and losses. The Money Market Portfolio will attempt to maintain
a constant net asset value of $1.00 per share.

         Securities held by all Portfolios other than the Money Market Portfolio
are valued based upon readily  available  market  quotations.  Where such market
quotations are not available,  securities are valued at fair value as determined
by or under the general  supervision  of the Board of  Trustees.  See "Net Asset
Values of the Shares of the Portfolios" in the SAI for details.


DIVIDENDS, OTHER DISTRIBUTIONS AND, TAXES
         Investors  should  understand  that,  as Owners,  they will not receive
directly  any  dividends  or other  distributions  from the  Trust or any of the
Portfolios.  All such  dividends  and other  distributions  are  payable to, and
reinvested by, the separate  accounts of the insurance company in which contract
premiums are invested.

         It  is  each  Portfolio's   intention  to  distribute   sufficient  net
investment  income  to  avoid  the  imposition  of  federal  income  tax  on the
Portfolio.  Each portfolio also intends to distribute sufficient income to avoid
the  application  of any federal  excise tax.  For  dividend  purposes,  the net
investment  income of each  Portfolio,  other than the Money  Market  Portfolio,
consists of all dividends and/or interest  received and any net short-term gains
from the sale of its  investments  less its estimated  expenses  (including fees
payable to the Adviser).  Net  investment  income of the Money Market  Portfolio
consists of accrued  interest  accrued (i) plus or minus amortized  discounts or
premiums,  (ii) plus all realized net short-term gains on portfolio  securities,
(iii) less the estimated expenses of that Portfolio  applicable to that dividend
period.  The Asset  Allocation  Portfolio  is also  required  to  include in its
taxable  income each year a portion of the original  issue  discount at which it
acquires zero coupon securities,  even though the Portfolio receives no interest
payment  on the  securities  during the year.  Similarly,  that  Portfolio  must
include  in its  taxable  income  each  year  any  interest  on  payment-in-kind
securities in the form of  additional  securities.  Accordingly,  to continue to
qualify for treatment as a regulated  investment  company  under the Code,  that
Portfolio  may be required to distribute as a dividend an amount that is greater
than  the  total  amount  of  cash  the  Portfolio  actually   receives.   Those
distributions will be made from the Portfolio's cash assets or the proceeds from
sales of portfolio securities, if necessary.

         Dividends from the Government  Securities  Portfolio and Corporate Bond
Portfolio  will be  declared  and  reinvested  monthly  in  additional  full and
fractional  shares of those  respective  Portfolios.  Dividends  from the Common
Stock  Portfolio  and  the  Asset  Allocation  Portfolio  will be  declared  and
reinvested   quarterly  in  additional  full  and  fractional  shares  of  those
respective  Portfolios.  Dividends  from  the  Money  Market  Portfolio  will be
declared and reinvested  daily in additional full and fractional  shares of that
Portfolio.  However,  the  Trustees  may  decide to declare  dividends  at other
intervals.

         Distributions of all capital gains (the excess of net long-term capital
gain over net short-term  capital loss) of a Portfolio,  if any, is declared and
paid to its  shareholders  annually  after the close of its fiscal year. See the
applicable Contract prospectus for information  regarding

                                       23

the federal  income tax  treatment of  distributions  to the  insurance  company
separate accounts.

         Each  Portfolio of the Trust is treated as a separate  corporation  for
federal  income tax purposes  and intends to qualify as a "regulated  investment
company" under  Subchapter M of the Internal  Revenue Code of 1986 (the "Code").
As such,  a portfolio  will not be subject to federal  income tax on the part of
its net investment  income and net realized capital gains that it distributes to
shareholders. To qualify for treatment as a "regulated investment company," each
Portfolio  must,  among  other  things,  derive at least 90 percent of its gross
income for each taxable year from dividends, interest and gains from the sale or
other disposition of securities.

INVESTMENT PERFORMANCE
         Each  of the  Portfolios  may  from  time  to  time  advertise  certain
investment  performance  information.  Performance  information  may  consist of
yield,  effective yield, and average annual total return  quotations  reflecting
the deduction of all applicable  charges over a period of time. A Portfolio also
may use aggregate  total return figures for various  periods,  representing  the
cumulative  change in value of an  investment  in a Portfolio  for the  specific
period.  Performance  information  may be shown in schedules,  charts or graphs.
These figures are based on historical  earnings and are not intended to indicate
future performance.

APPENDIX A--SECURITIES RATINGS

DESCRIPTION OF CORPORATE BOND
RATINGS

Moody's Investor Service, Inc.'s Corporate Bond Ratings:
         Aaa--Bonds  which are  rated  Aaa by  Moody's  Investor  Service,  Inc.
("Moody's")  are judged to be the best quality and carry the smallest  degree of
investment  risk.   Interest  payments  are  protected  by  a  large  or  by  an
exceptionally  stable  margin,  and  principal  is  secure.  While  the  various
protective  elements are likely to change, such changes as can be visualized are
most unlikely to impair the fundamentally strong position of such issues.

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

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

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

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

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

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

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

Standard & Poor's Corporation's Corporate Bond Ratings:

         AAA--This is the highest  rating  assigned by Standard & Poor's ("S&P")
to a debt obligation and indicates an extremely strong capacity to pay principal
and interest.

         AA--Bonds  rated AA also  qualify  as  high-quality  debt  obligations.
Capacity to pay  principal  and interest is very strong,  and in the majority of
instances they differ from AAA issues only in small degree.

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

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

         BB/B/CCC/CC--Bonds  rated BB, B, CCC, and CC are regarded,  on balance,
as  predominantly  speculative  with  respect to the  issuer's  capacity  to pay
interest and repay principal in accordance with the terms of the obligation.  BB
indicates  the  lowest  degree  of  

                                       28

                                                            CONSECO SERIES TRUST

                                                                     1998

                                                                   PROSPECTUS
- --------------------------------------------------------------------------------

speculation  and CC the  highest  degree of  speculation.  While such bonds will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposure to adverse conditions.

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

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

         Plus (+) or Minus (-):  The 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.

Preferred Stock Ratings:
         Both Moody's and S&P use the same  designations  for corporate bonds as
they do for preferred stock,  except that in the case of Moody's preferred stock
ratings,  the initial letter rating is not  capitalized.  While the descriptions
are  tailored  for  preferred  stocks and  relative  quality,  distinctions  are
comparable to those described above for corporate bonds.

DESCRIPTION OF COMMERCIAL PAPER RATINGS
         Among the factors  considered by Moody's in assigning  commercial paper
ratings are the following:  (1) evaluation of the management of the issuer;  (2)
economic  evaluation of the issuer's  industry or industries and an appraisal of
speculative-type risks which may be inherent in certain areas; (3) evaluation of
the issuer's  products in relation to competition and customer  acceptance;  (4)
liquidity;  (5) amount and quality of long-term debt; (6) trend of earnings over
a period  of 10  years;  (7)  financial  strength  of a parent  company  and the
relationships which exist with the issuer; and (8) recognition by the management
of obligations  which may be present or may arise as a result of public interest
questions and  preparations to meet such  obligations.  Relative  differences in
strengths and weaknesses in respect of these criteria  establish a rating in one
of three  classifications.  The rating Prime-1 is the highest  commercial  paper
rating  assigned  by  Moody's.  Its other two  ratings,  Prime-2 and Prime-3 are
designated Higher Quality and High Quality, respectively.  Issuers rated Prime-2
have a strong capacity for repayment of short-term promissory obligations.

         Commercial  paper  rated A by S&P has  the  following  characteristics:
Liquidity ratios are adequate to meet cash  requirements.  Long-term senior debt
is rated A or better,  although in some cases BBB  credits  may be allowed.  The
issuer  has  access to at least two  additional  channels  of  borrowing.  Basic
earnings  and cash flow have an upward  trend with  allowance  made for  unusual
circumstances.  Typically  the  issuer's  industry is well  established  and the
issuer has a strong position within the industry. The reliability and quality of
management are unquestioned.  The rating A is described by S&P as the investment
grade  category,  the highest  rating  classification.  Relative  strengths  and
weaknesses of the above factors determine whether the issuer's  commercial paper
is rated  A-1,  A-2 or A-3.  The A-1  designation  indicates  that the degree of
safety regarding  timely payment is very strong.  Issues rated A-1+ are those of
an overwhelming degree of credit protection.  The A-2 designation indicates that
the capacity for timely payment is strong.

INVESTMENT PERFORMANCE

    The  methods  by  which  the  investment  performance  of the  Money  Market
Portfolio (see the Prospectus) are calculated for a specified period of time are
described below.

    The first  method,  which  results in an amount  referred to as the "current
yield," assumes an account  containing exactly one share at the beginning of the
period.  (The  net  asset  value  of this  share  will  be  $1.00  except  under
extraordinary  circumstances.) The net change in the value of the account during
the period is then determined by subtracting this beginning value from the value
of the  account  at the  end of the  period;  however,  capital  changes  (i.e.,
realized   gains  and  losses  from  the  sale  of  securities   and  unrealized
appreciation and depreciation) are excluded from the calculation.

    This net  change in the  account  value is then  divided by the value of the
account at the beginning of the period (i.e., normally $1.00 as discussed above)
and the  resulting  figure  (referred  to as the "base  period  return") is then
annualized  by  multiplying  it by 365 and dividing by the number of days in the
period;  the result is the "current  yield." Normally a seven-day period will be
used in  determining  yields  (both the current  yield and the  effective  yield
discussed below) in published or mailed advertisements.

    The  second  method  results  in an amount  referred  to as the  "compounded
effective  yield." This  represents an  annualization  of the current yield with
dividends  reinvested daily. This compounded effective yield is calculated for a
seven-day  period by compounding the  unannualized  base period return by adding
one to the base period  return,  raising the sum to a power equal to 365 divided
by seven and subtracting one from the result.

    Yield information may be useful to investors in reviewing the performance of
the Money Market  Portfolio.  However,  a number of factors should be taken into
account  before  using  yield   information  as  a  basis  for  comparison  with
alternative  investments.  An  investment  in the Money Market  Portfolio is not
insured and its yields are not guaranteed. The yields normally will fluctuate on
a daily  basis.  The yields for any given past period are not an  indication  or
representation by the Trust of future yields or rates of return on the shares of
the Money Market Portfolio and, therefore,  they cannot be compared to yields on
savings  accounts  or  other  investment  alternatives  which  often  provide  a
guaranteed  fixed  yield for a stated  period of time,  and may be  insured by a
government  agency. In comparing the yields of one money market fund to another,
consideration  should  be  given to each  fund's  investment  policy,  portfolio
quality, portfolio maturity, type of instruments held and operating expenses. In
addition,  the yield of the Money  Market  Portfolio as well as the yield of the
Corporate  Bond,  Government  Securities,  Common  Stock  and  Asset  Allocation
Portfolios  will each be affected by charges  imposed by the  separate  accounts
that invest in the  Portfolios.  See the Prospectus of the  applicable  separate
account for details.

    The Corporate Bond Portfolio,  Government Securities Portfolio, Common Stock
Portfolio,  and Asset Allocation Portfolio may advertise investment  performance
figures,  including yield.  Each  Portfolio's  yield will be based upon a stated
30-day  period and will be computed by dividing  the net  investment  income per
share earned  during the period by the maximum  offering  price per share on the
last day of the period, according to the following formula:

    YIELD = 2 ((A-B/CD)+1)6-1

    Where:

    A = the dividends and interest earned during the period.
    B = the expenses accrued for the period (net of reim- bursements, if any).
    C = the average  daily number of shares  outstanding  during the period that
        were entitled to receive dividends.
    D = the maximum  offering prices (which is the net asset value) per share on
        the last day of the period.

    Each of the  Portfolios  may advertise  its total return and its  cumulative
total  return.  The total return will be based upon a stated  period and will be
computed by finding the average annual compounded rate of return over the stated
period that would  equate an initial  amount  invested to the ending  redeemable
value of the investment (assuming reinvestment of all distributions),  according
to the following formula:

    P (1+T)n=ERV

    Where:

    P      = a hypothetical  initial payment of $1,000.
    T      = the average annual total return.
    n      = the number of years.
    ERV    = the ending  redeemable  value at the end of the stated  period of a
             hypothetical  $1,000

                                      B-1
<PAGE>

================================================================================

payment made at the beginning of the stated period.

    The  cumulative  total return will be based upon a stated period and will be
computed by dividing the ending redeemable value of a hypothetical investment by
the   value  of  the   initial   investment   (assuming   reinvestment   of  all
distributions).

    Each investment  performance figure will be carried to the nearest hundredth
of one percent.

DESCRIPTION OF SECURITIES AND
INVESTMENT TECHNIQUES

    The following  discussion  describes in greater  detail  different  types of
securities  and investment  techniques  used by the  individual  Portfolios,  as
described  in  "Investment  Objectives  and Policies of the  Portfolios"  in the
Prospectus, as well as the risks associated with such securities and techniques.

    All of the Portfolios may invest in U.S. government  securities as described
in the Prospectus.

    All  Portfolios  may  also  purchase  obligations  of the  World  Bank,  the
Inter-American Development Bank, the Asian Development Bank, and the World Bank,
which are,  not U.S.  government  agencies,  but have the ability to borrow from
member countries, including the United States.
    
MORTGAGE-BACKED SECURITIES

    Each  Portfolio  other  than  the  Money  Market  Portfolio  may  invest  in
mortgage-backed securities.

    MORTGAGE  PASS-THROUGH   SECURITIES.   These  are  securities   representing
interests in "pools" of mortgages in which  periodic  payments of both  interest
and principal on the securities are made by "passing  through" periodic payments
made by the individual  borrowers on the residential  mortgage loans  underlying
such  securities  (net of fees paid to the issuer or guarantor of the securities
and possibly other costs). Early repayment of principal on mortgage pass-through
securities  (arising from prepayments of principal due to sale of the underlying
property,  refinancing,  or  foreclosure,  net of fees and  costs  which  may be
incurred) may expose a Portfolio to a lower rate of return upon  reinvestment of
principal.  Payment of  principal  and  interest on some  mortgage  pass-through
securities may be guaranteed by the full faith and credit of the U.S. government
(in the  case of  securities  guaranteed  by the  Government  National  Mortgage
Association, "GNMA"), or guaranteed by agencies or instrumentalities of the U.S.
government  (in the  case  of  securities  guaranteed  by the  Federal  National
Mortgage  Association,  "FNMA," or the Federal Home Loan  Mortgage  Corporation,
"FHLMC").  Mortgage pass-through securities created by non-governmental  issuers
(such as  commercial  banks,  savings and loan  institutions,  private  mortgage
insurance  companies,  mortgage bankers, and other secondary market issuers) may
be uninsured or may be  supported by various  forms of insurance or  guarantees,
including  individual loan,  title,  pool and hazard  insurance,  and letters of
credit, which may be issued by governmental  entities,  private insurers, or the
mortgage poolers.

    GNMA  CERTIFICATES.   GNMA  certificates  are   mortgage-backed   securities
representing  part ownership of a pool of mortgage loans on which timely payment
of interest and principal is guaranteed by the full faith and credit of the U.S.
Government.  GNMA  certificates  differ from typical bonds because  principal is
repaid  monthly over the term of the loan rather than  returned in a lump sum at
maturity.  Although the mortgage loans in the pool will have maturities of up to
30 years,  the actual  average life of the GNMA  certificates  typically will be
substantially  less because the  mortgages may be purchased at any time prior to
maturity, will be subject to normal principal  amortization,  and may be prepaid
prior to  maturity.  Reinvestment  of  prepayments  may occur at higher or lower
rates than the original yield on the certificates.

    FNMA AND FHLMC MORTGAGE-BACKED OBLIGATIONS.  FNMA, a federally chartered and
privately  owned  corporation,   issues  pass-through   securities  representing
interests in a pool of conventional  mortgage loans.  FNMA guarantees the timely
payment of principal and interest,  but this guarantee is not backed by the full
faith and credit of the U.S.  government.  FNMA also issues REMIC  certificates,
which  represent  interests  in a trust  funded  with FNMA  certificates.  REMIC
certificates  are guaranteed by FNMA and not by the full faith and credit of the
U.S. Government.

    FHLMC,  a  corporate   instrumentality  of  the  U.S.   government,   issues
participation certificates which represent an interest in a pool of conventional
mortgage loans. FHLMC guarantees the timely payment of interest and the ultimate
collection  of  principal,  and maintains  reserves to protect  holders  against
losses due to default, but these securities are not backed by the full faith and
credit of the U.S. government. As is the case with GNMA certificates,

                                      B-2
<PAGE>

================================================================================

the  actual  maturity  of and  realized  yield  on  particular  FNMA  and  FHLMC
pass-through  securities  will vary based on the  prepayment  experience  of the
underlying pool of mortgages.

    OTHER MORTGAGE-BACKED SECURITIES. All Portfolios other than the Money Market
Portfolio   may  purchase   mortgage-backed   securities   issued  by  financial
institutions such as commercial banks,  savings and loan associations,  mortgage
banks,  and  securities  broker-dealers  (or  affiliates  of  such  institutions
established  to issue  these  securities)  in the form of either  collateralized
mortgage  obligations  ("CMOs") or  mortgage-backed  bonds. CMOs are obligations
fully  collateralized  directly or  indirectly  by a pool of  mortgages on which
payments of principal  and interest  are  dedicated to payment of principal  and
interest  on the CMOs.  Payments  are passed  through to the holders on the same
schedule as they are received.  Mortgage-backed bonds are general obligations of
the issuer fully  collateralized  directly or indirectly by a pool of mortgages.
The mortgages  serve as collateral for the issuer's  payment  obligations on the
bonds but  interest  and  principal  payments  on the  mortgages  are not passed
through  either  directly  (as  with  GNMA   certificates  and  FNMA  and  FHLMC
pass-through securities) or on a modified basis (as with CMOs).  Accordingly,  a
change in the rate of  prepayments  on the pool of  mortgages  could  change the
effective  maturity of a CMO but not that of a  mortgage-backed  bond (although,
like many bonds,  mortgage-backed  bonds may be callable by the issuer  prior to
maturity).  Although the mortgage-related  securities securing these obligations
may be subject to a government  guarantee or third-party support, the obligation
itself  is  not  so  guaranteed.  Therefore,  if  the  collateral  securing  the
obligation is  insufficient  to make payment on the  obligation,  a holder could
sustain a loss. If new types of  mortgage-related  securities  are developed and
offered to other types of  investors,  investments  in such  securities  will be
considered.

    RISKS OF MORTGAGE-BACKED  SECURITIES.  In the case of mortgage  pass-through
securities,  such  as  GNMA  certificates  or  FNMA  and  FHLMC  mortgage-backed
obligations, or modified pass-through securities, such as CMOs issued by various
financial institutions, early repayment of principal arising from prepayments of
principal on the  underlying  mortgage  loans due to the sale of the  underlying
property,  the refinancing of the loan, or foreclosure may expose a Portfolio to
a lower rate of return upon reinvestment of the principal. Prepayment rates vary
widely  and may be  affected  by  changes  in  market  interest  rates and other
economic trends and factors.  In periods of falling  interest rates, the rate of
prepayment tends to increase,  thereby shortening the actual average life of the
mortgage-backed security.  Conversely,  when interest rates are rising, the rate
of prepayment tends to decrease,  thereby lengthening the actual average life of
the  mortgage-backed  security.  Accordingly,  it is not possible to  accurately
predict the average life of a particular  pool.  Reinvestment of prepayments may
occur at  higher  or lower  rates  than the  original  yield on the  securities.
Therefore,  the actual  maturity and realized yield on  pass-through or modified
pass-through  mortgage-backed  securities  will vary based  upon the  prepayment
experience of the underlying pool of mortgages.

ASSET-BACKED SECURITIES

    Each  Portfolio   other  than  the  Money  Market   Portfolio  may  purchase
asset-backed   securities   such  as  "CARs"   ("Certificates   for   Automobile
Receivables") and Credit Card Receivable  Securities and any other  asset-backed
securities that may be developed in the future.

DEBT SECURITIES

    All  Portfolios  may  invest  in  U.S.  dollar-denominated   corporate  debt
securities  of domestic  issuers,  and the Asset  Allocation  Portfolio  and the
Corporate Bond Portfolio may invest in debt  securities of foreign  issuers that
may or may not be U.S.
dollar-denominated.

    The  investment  return  on a  corporate  debt  security  reflects  interest
earnings  and changes in the market value of the  security.  The market value of
corporate  debt  obligations  may be  expected to rise and fall  inversely  with
interest  rates  generally.  There also  exists the risk that the issuers of the
securities  may not be able to meet their  obligations  on interest or principal
payments at the time called for by an instrument.  Debt securities  rated BBB or
Baa, which are considered  medium-grade  category debt  securities,  do not have
economic  characteristics  that provide the high degree of security with respect
to  payment  of  principal  and  interest  associated  with  higher  rated  debt
securities, and generally have some speculative characteristics. A debt security
will be placed in this rating  category  where  interest  payments and principal
security  appear  adequate for the present,  but economic  characteristics  that
provide  longer  term  protection  may  be  lacking.  Any  debt  security,   and
particularly  those rated BBB or Baa (or below),  may be susceptible to changing
conditions,  particularly to economic downturns,  which could lead to a weakened
capacity to pay interest and principal.

    New issues of certain debt securities are often

                                      B-3
<PAGE>

================================================================================

offered  on a  when-issued  or delayed  delivery  basis;  that is,  the  payment
obligation and the interest rate are fixed at the time the buyer enters into the
commitment,  but delivery  and payment for the  securities  normally  take place
after the  customary  settlement  time.  The  value of  when-issued  or  delayed
delivery  securities  may vary prior to and after  delivery  depending on market
conditions  and changes in interest rate levels.  However,  a Portfolio will not
accrue  any income on these  securities  prior to  delivery.  A  Portfolio  will
maintain in a segregated account with the Trust's custodian an amount of cash or
liquid securities equal (on a daily  mark-to-market  basis) to the amount of its
commitment to purchase the when-issued or delayed delivery securities.

    As discussed more fully in the  Prospectus,  the Money Market  Portfolio may
invest in rated debt securities only if they are rated in one of the two highest
short-term  ratings  categories.  The Corporate  Bond  Portfolio and  Government
Securities Portfolio will invest in rated debt securities only if they are rated
"investment grade," except that the Corporate Bond Portfolio may invest up to 10
percent of the Portfolio's assets in non-investment  grade debt securities.  The
Common  Stock and Asset  Allocation  Portfolios  will not  invest in rated  debt
securities  which are rated below CCC/Caa.  All Portfolios may invest in unrated
securities  as  long  as  the  Adviser  determines  that  such  securities  have
investment  characteristics  comparable to securities that would be eligible for
investment  by a Portfolio  by virtue of a rating.  Many  securities  of foreign
issuers are not rated by Moody's or Standard & Poor's;  therefore, the selection
of such issuers depends,  to a large extent, on the credit analysis performed or
used by the Adviser.

    RISKS  ASSOCIATED  WITH HIGH YIELD  DEBT  SECURITIES.  The Asset  Allocation
Portfolio,  Common Stock Portfolio,  and the Corporate Bond Portfolio may invest
in  high  yield,  high  risk,  lower-rated  debt  securities.  High  yield  debt
securities  are  subject  to all  risks  inherent  in  any  investment  in  debt
securities.  As discussed below,  these risks are  significantly  greater in the
case of high yield debt securities.
   
    Lower-rated fixed income securities generally offer a higher yield than that
available from higher-rated issues with similar maturities,  as compensation for
holding a security  that is subject to greater  risk.  Lower-rated  fixed income
securities are deemed by rating agencies to be  predominately  speculative  with
respect to the issuer's  capacity to pay interest  and repay  principal  and may
involve  major risk or exposure to adverse  conditions.  Lower-rated  securities
involve higher risks in that they are especially  subject to (1) adverse changes
in general  economic  conditions  and in the industries in which the issuers are
engaged,  (2) adverse  changes in the  financial  condition of the issuers,  (3)
price  fluctuation  in  response  to changes in  interest  rates and (4) limited
liquidity and secondary market support.

    An economic downturn  affecting the issuer may result in a weakened capacity
to make principal and interest  payments and an increased  incidence of default.
In addition, a fund that invests in lower-rated  securities may incur additional
expenses to the extent  recovery is sought on defaulted  securities.  Because of
the many risks involved in investing in high yield fixed income securities,  the
success  of such  investments  is  dependent  upon the  credit  analysis  of the
Adviser. Although the market for lower-rated fixed income securities is not new,
and the market has previously weathered economic downturns, the past performance
of the market  for such  securities  may not be an  accurate  indication  of its
performance  during  future  economic  downturns  or periods of rising  interest
rates.  This  market may be thinner  and less  active than the market for higher
quality securities, which may limit the ability to sell such securities at their
fair  value in  response  to changes in the  economy or the  financial  markets.
Adverse publicity and investor perceptions,  whether or not based on fundamental
analysis, may also decrease the values and liquidity of lower-rated  securities,
especially in a thinly traded market. Differing yields on debt securities of the
same  maturity  are a  function  of  several  factors,  including  the  relative
financial strength of the issuers.
    
    Differing  yields on fixed  income  securities  of the same  maturity  are a
function of several factors,  including the relative  financial  strength of the
issuers.  Higher  yields are generally  available  from  securities  rated below
investment  grade  categories  of  recognized  rating  agencies:  Ba or lower by
Moody's  or BB or lower by  Standard  &  Poor's.  Debt  securities  rated  below
investment  grade are deemed by these agencies to be  predominantly  speculative
with respect to the issuer's  capacity to pay interest and repay  principal  and
may involve major risk exposure to adverse conditions.

    Although Conseco Capital Management, Inc. ("the Adviser") considers security
ratings  when  making  investment  decisions,  it  performs  its own  investment
analysis  and does not rely  principally  on the ratings  assigned by the rating
services.  The  Adviser's  analysis  may include  consideration  of the issuer's
experience and managerial  strength,  changing  financial  condition,  borrowing
requirements  or debt maturity  schedules,  and the issuer's  responsiveness  to
changes in business  conditions and interest rates.  It also considers

                                      B-4
<PAGE>

================================================================================

relative values based on anticipated cash flow,  interest or dividend  coverage,
asset coverage and earnings prospects.

    Also, the Adviser buys and sells debt securities  principally in response to
its evaluation of an issuer's  continuing  ability to meet its obligations,  the
availability of better investment  opportunities,  and its assessment of changes
in business  conditions and interest rates.  From time to time,  consistent with
the Common Stock  Portfolio's and the Asset  Allocation  Portfolio's  investment
objectives,  the  Adviser  may also trade high  yield  debt  securities  for the
purpose  of  seeking  short-term  profits.  These  securities  may  be  sold  in
anticipation  of a market  decline or bought in  anticipation  of a market rise.
They may also be traded for  securities  of  comparable  quality and maturity to
take advantage of perceived short-term disparities in market values or yields.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES

    The Trust  may,  on  behalf  of each  Portfolio,  purchase  securities  on a
when-issued  or  delayed  delivery  basis.   When-issued  and  delayed  delivery
transactions  arise when  securities are bought with payment and delivery taking
place in the future. The settlement dates of these transactions,  which may be a
month or more after  entering  into the  transaction,  are  determined by mutual
agreement of the parties. The Trust bears the risk that, on the settlement date,
the market value of the securities may vary from the purchase price. At the time
the Trust makes a commitment to purchase securities on a when- issued or delayed
delivery basis, it will record the transaction and reflect the value each day of
such securities in determining the net asset value of the Portfolio in question.
There are no fees or other expenses  associated with these types of transactions
other  than  normal  transaction  costs.  To the  extent  the Trust  engages  in
when-issued and delayed delivery transactions,  it will do so for the purpose of
acquiring  portfolio  instruments  consistent with the investment  objective and
policies  of the  respective  Portfolio  and not for the  purpose of  investment
leverage or to speculate on interest rate changes.  When  effecting  when-issued
and delayed delivery  transactions,  cash or liquid securities of a Portfolio in
an amount sufficient to make payment for the obligations to be purchased will be
segregated  at the trade  date and  maintained  until the  transaction  has been
settled.  The Adviser will ensure that such assets are  segregated  at all times
and are  sufficient to satisfy these  obligations.  The Portfolio may dispose of
these securities  before the issuance  thereof.  However,  absent  extraordinary
circumstances  not presently  foreseen,  it is the Trust's  policy not to divest
itself of its right to acquire these  securities  prior to the  settlement  date
thereof.

VARIABLE AND FLOATING RATE SECURITIES

    Each Portfolio may invest in variable and floating rate securities. Variable
rate securities  provide for automatic  establishment  of a new interest rate at
fixed intervals  (i.e.,  daily,  monthly,  semi-annually,  etc.).  Floating rate
securities  provide for automatic  adjustment of the interest rate whenever some
specified interest rate index changes. The interest rate on variable or floating
rate securities is ordinarily determined by reference to, or is a percentage of,
a bank's prime rate,  the 90-day U.S.  Treasury bill rate, the rate of return on
commercial  paper or bank  certificates  of  deposit,  an  index  of  short-term
interest rates, or some other objective measure.

    Variable or floating rate  securities  frequently  include a demand  feature
entitling the holder to sell the securities to the issuer at par value.  In many
cases, the demand feature can be exercised at any time on seven days' notice; in
other cases, the demand feature is exercisable at any time on 30 days' notice or
on similar notice at intervals of not more than one year.

BANKING INDUSTRY AND SAVINGS INDUSTRY OBLIGATIONS

    Each  Portfolio  may  invest in  certificates  of  deposit,  time  deposits,
bankers' acceptances, and other short-term debt obligations issued by commercial
banks and in  certificates  of  deposit,  time  deposits,  and other  short-term
obligations  issued by savings and loan associations  ("S&Ls").  Certificates of
deposit are receipts  from a bank or an S&L for funds  deposited for a specified
period of time at a specified rate of return. Time deposits in banks or S&Ls are
generally similar to certificates of deposit,  but are uncertificated.  Bankers'
acceptances are time drafts drawn on commercial  banks by borrowers,  usually in
connection  with  international  commercial   transactions.   The  Money  Market
Portfolio,  Common Stock  Portfolio and Corporate Bond Portfolio may each invest
in  obligations  of foreign  branches of domestic  commercial  banks and foreign
banks  so  long  as  the  securities  are  U.S.  dollar-denominated.  The  Asset
Allocation  Portfolio  may also  invest in these types of  instruments  but such
instruments  will not  necessarily  be U.S.  dollar-  denominated.  See "Foreign
Securities" below for information regarding risks associated with investments in
foreign securities.

    The Portfolios will not invest in obligations issued by a commercial bank or
S&L unless:

                                      B-5
<PAGE>

================================================================================

1.   The bank or S&L has total assets of at least $1 billion,  or the equivalent
     in other currencies, and the institution has outstanding securities rated A
     or better by Moody's or Standard & Poor's,  or, if the  institution  has no
     outstanding  securities  rated by Moody's or Standard & Poor's,  it has, in
     the determination of the Adviser, similar credit-worthiness to institutions
     having outstanding securities so rated;

2.   In  the case of a U.S. bank or S&L, its deposits are federally insured; and

3.   In the case of a foreign bank, the security is, in the determination of the
     Adviser,  of an investment  quality  comparable  with other debt securities
     which may be purchased by the Portfolio.  These limitations do not prohibit
     investments  in  securities  issued  by  foreign  branches  of U.S.  banks,
     provided such U.S. banks meet the foregoing requirements.

REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS

    Each Portfolio may enter into repurchase  agreements and reverse  repurchase
agreements.  Repurchase  agreements permit an investor to maintain liquidity and
earn income over periods of time as short as overnight. In these transactions, a
Portfolio purchases U.S. Treasury obligations or U.S. government securities (the
"underlying  securities")  from a broker or bank, which agrees to repurchase the
underlying  securities  on a  certain  date or on  demand  and at a fixed  price
calculated to produce a previously  agreed upon return to the Portfolio.  If the
broker or bank were to default on its  repurchase  obligation and the underlying
securities were sold for a lesser amount,  the Portfolio would realize a loss. A
repurchase  transaction  will be subject to guidelines  approved by the Board of
Trustees of the Trust,  which include  monitoring the  credit-worthiness  of the
parties with which the Portfolio engages in repurchase  transactions,  obtaining
collateral at least equal in value to the repurchase obligation, and marking the
collateral to market on a daily basis.

    A reverse repurchase  agreement involves the temporary sale of a security by
a Portfolio and its agreement to repurchase  the  instrument at a specified time
and price.  Such agreements are short-term in nature. A Portfolio will segregate
cash or liquid securities whenever it enters into reverse repurchase agreements.
Such transactions may be considered to be borrowings.

    Although  not one of the  Trust's  fundamental  policies,  it is the Trust's
present policy not to enter into a repurchase  transaction which will cause more
than 10 percent of the assets of the Money Market Portfolio,  the Corporate Bond
Portfolio or the  Government  Securities  Portfolio to be subject to  repurchase
agreements having a maturity of more than seven days. This 10 percent limit also
includes  the  aggregate  of (i)  fixed  time  deposits  subject  to  withdrawal
penalties,  other than overnight  deposits;  and (ii) any restricted  securities
(i.e.,  securities  which  cannot  freely  be sold for  legal  reasons)  and any
securities for which market quotations are not readily available;  however, this
10 percent limit does not include any  obligations  payable at principal  amount
plus accrued  interest,  on demand or within seven days after  demand,  and thus
does not include repurchase agreements having a maturity of seven days or less.

RESTRICTED AND ILLIQUID SECURITIES

    The Common Stock Portfolio, the Asset Allocation Portfolio and the Corporate
Bond Portfolio may invest in restricted  securities such as private  placements,
although a Portfolio  may not invest in any  illiquid  restricted  security  if,
after acquisition thereof,  more than 15 percent of the Portfolio's assets would
be invested in illiquid securities. Once acquired,  restricted securities may be
sold by a Portfolio  only in privately  negotiated  transactions  or in a public
offering with respect to which a  registration  statement is in effect under the
Securities  Act of  1933.  If  sold in a  privately  negotiated  transaction,  a
Portfolio may have  difficulty  finding a buyer and may be required to sell at a
price that is less than the  Adviser  had  anticipated.  Where  registration  is
required,  a Portfolio  may be obligated to pay all or part of the  registration
expenses and a  considerable  period may elapse between the time of the decision
to sell and the time the Portfolio may be permitted to sell a security  under an
effective  registration  statement.  If,  during such a period,  adverse  market
conditions  were to develop,  the Portfolio  might obtain a less favorable price
than prevailed when it decided to sell.

WARRANTS

    The Common  Stock and Asset  Allocation  Portfolios  may invest in warrants.
Each of these  Portfolios  may  invest  up to 5  percent  of its net  assets  in
warrants  (not  including  those that have been acquired in units or attached to
other securities),  measured at the time of acquisition, and each such Portfolio
may acquire a warrant not listed on the New York or American Stock Exchanges if,
after such  acquisition,  no more than 2 percent of the  Portfolio's  net assets
would be invested in such warrants.

                                      B-6
<PAGE>

================================================================================

    The holder of a warrant has the right to  purchase a given  number of shares
of a security of a particular  issuer at a specified  price until  expiration of
the warrant.  Such investments provide greater potential for profit or loss than
a direct  purchase of the same amount of the  securities.  Prices of warrants do
not necessarily move in tandem with the prices of the underlying securities, and
are  considered  speculative  investments.  They pay no dividends  and confer no
rights other than a purchase  option.  If a warrant is not exercised by the date
of its expiration, a Portfolio would lose its entire investment in such warrant.

FOREIGN SECURITIES

    The Asset  Allocation  Portfolio may invest in equity  securities of foreign
issuers.  That  Portfolio  may invest up to 50 percent of its net assets in such
securities. The Asset Allocation Portfolio and Common Stock Portfolio may invest
in  American  Depository  Receipts  ("ADRs"),  which are  described  below.  The
Corporate  Bond  Portfolio may invest in debt  obligations  of foreign  issuers,
including  foreign   governments  and  their  agencies  and   instrumentalities.
Investments in foreign  securities may offer unique  potential  benefits such as
substantial  growth in industries not yet developed in the  particular  country.
Such  investments  also permit a Portfolio to invest in foreign  countries  with
economic  policies or business cycles different from those of the United States,
or to reduce  fluctuations  in  portfolio  value by taking  advantage of foreign
stock  markets  that  may  not  move  in a  manner  parallel  to  U.S.  markets.
Investments  in  securities  of  foreign   issuers  involve  certain  risks  not
ordinarily  associated with investments in securities of domestic issuers.  Such
risks  include  fluctuations  in foreign  exchange  rates,  U.S.  also,  and the
possible  imposition of exchange controls or other foreign  governmental laws or
restrictions.  In  addition,  with  respect to certain  countries,  there is the
possibility of  expropriation  of assets,  confiscatory  taxation,  political or
social  instability,  or diplomatic  developments  that could  adversely  affect
investments in those countries.  Since the Asset Allocation Portfolio may invest
in securities  denominated or quoted in currencies  other than the U.S.  dollar,
changes in foreign  currency  exchange rates will affect the value of securities
in that Portfolio and the unrealized appreciation or depreciation of investments
so far as U.S. investors are concerned.

    There may be less publicly  available  information  about a foreign  company
than  about  a U.S.  company,  and  foreign  companies  may  not be  subject  to
accounting,   auditing,  and  financial  reporting  standards  and  requirements
comparable  to or as  uniform  as those to which  U.S.  companies  are  subject.
Foreign securities  markets,  while growing in volume,  have, for the most part,
substantially  less  volume  than  U.S.  markets.  Securities  of  many  foreign
companies  are less liquid and their prices more  volatile  than  securities  of
comparable U.S. companies.  Transactional  costs in non-U.S.  securities markets
are generally higher than in U.S.  securities  markets.  There is generally less
government  supervision and regulation of exchanges,  brokers,  and issuers than
there is in the United States. A Portfolio might have greater  difficulty taking
appropriate legal action with respect to foreign investments in non-U.S.  courts
than with respect to domestic issuers in U.S. courts. In addition,  transactions
in  foreign  securities  may  involve  greater  time from the trade  date  until
settlement  than  domestic  securities  transactions  and  involve  the  risk of
possible  losses  through the holding of securities by custodians and securities
depositories in foreign countries.

    Dividend  and  interest  income from  foreign  securities  may  generally be
subject to  withholding  taxes by the country in which the issuer is located and
may not be recoverable by a Portfolio or its investors in all cases.

    ADRs are  certificates  issued by a U.S. bank or trust company  representing
the right to  receive  securities  of a foreign  issuer  deposited  in a foreign
subsidiary  or branch  or a  correspondent  of that  bank.  Generally,  ADRs are
designed for use in U.S.  securities  markets and may offer U.S.  investors more
liquidity  than  the  underlying   securities.   The  Portfolio  may  invest  in
unsponsored  ADRs. The issuers of unsponsored ADRs are not obligated to disclose
material information in the U.S. and, therefore,  there may not be a correlation
between such information and the market value of such ADRs.

FUTURES CONTRACTS

    The Common Stock, Corporate Bond, Government Securities and Asset Allocation
Portfolios  may engage in futures  contracts  and may purchase and sell interest
rate futures  contracts.  The Common Stock and Asset  Allocation  Portfolios may
purchase  and  sell  stock  index  futures  contracts,   interest  rate  futures
contracts,  and futures  contracts  based upon other  financial  instruments and
components.  The Asset  Allocation  Portfolio  may also engage in gold and other
precious metals futures contracts.

    Such investments may be made by these  Portfolios  solely for the purpose of
hedging against the effect that changes in general market  conditions,  interest
rates, and conditions affecting particular  industries may have on the values of
securities held in a Portfolio or in

                                      B-7

which a Portfolio intends to purchase, and not for purposes of speculation.

    GENERAL  DESCRIPTION OF FUTURES  CONTRACTS.  A futures contract provides for
the future sale by one party and purchase by another party of a specified amount
of a  particular  financial  instrument  (debt  security)  or  commodity  for  a
specified  price  at a  designated  date,  time,  and  place.  Although  futures
contracts by their terms require  actual future  delivery of and payment for the
underlying financial  instruments,  such contracts are usually closed out before
the delivery date.  Closing out an open futures contract position is effected by
entering  into  an  offsetting  sale or  purchase,  respectively,  for the  same
aggregate  amount of the same  financial  instrument on the same delivery  date.
Where a Portfolio has sold a futures  contract,  if the offsetting price is more
than the original  futures  contract  purchase price,  the Portfolio  realizes a
gain; if it is less, the Portfolio realizes a loss.
   
    At the time a Portfolio enters into a futures  contract,  an amount of cash,
or liquid  securities  equal to the fair market value less initial margin of the
futures  contract,  will be deposited  in a segregated  account with the Trust's
custodian to  collateralize  the  position and thereby  ensure that such futures
contract is covered. A Portfolio may be required to deposit additional assets in
the  segregated  account in order to continue  covering  the  contract as market
conditions  change.  In  addition,  each  Portfolio  will  comply  with  certain
regulations  of the  Commodity  Futures  Trading  Commission  to qualify  for an
exclusion from being a "commodity pool operator".

    INTEREST  RATE  FUTURES  CONTRACTS.   The  Common  Stock,   Corporate  Bond,
Government  Securities  and Asset  Allocation  Portfolios  may purchase and sell
interest  rate  futures  contracts.  An  interest  rate  futures  contract is an
obligation  traded on an exchange or board of trade that  requires the purchaser
to accept delivery,  and the seller to make delivery, of a specified quantity of
the underlying financial instrument, such as U.S. Treasury bills and bonds, in a
stated delivery month, at a price fixed in the contract.
    
    These  Portfolios  may  purchase and sell  interest  rate futures as a hedge
against  changes  in  interest  rates  that  adversely  impact the value of debt
instruments  and  other  interest  rate  sensitive  securities  being  held by a
Portfolio. A Portfolio might employ a hedging strategy whereby it would purchase
an interest  rate futures  contract  when it is not fully  invested in long-term
debt  securities  but wishes to defer their purchase until it can orderly invest
in such  securities  or because  short-term  yields are  higher  than  long-term
yields.  Such a  purchase  would  enable the  Portfolio  to earn the income on a
short-term  security while at the same time minimizing the effect of all or part
of an increase in the market  price of the  long-term  debt  security  which the
Portfolio  intends  to  purchase  in the  future.  A rise  in the  price  of the
long-term  debt  security  prior to its  purchase  either  would be offset by an
increase in the value of the futures  contract  purchased  by the  Portfolio  or
avoided by taking delivery of the debt securities under the futures contract.

    A Portfolio  would sell an  interest  rate  futures  contract to continue to
receive the income from a long-term  debt security,  while  endeavoring to avoid
part or all of the  decline  in  market  value  of  that  security  which  would
accompany an increase in interest  rates.  If interest  rates rise, a decline in
the value of the debt  security  held by the  Portfolio  would be  substantially
offset by the  ability  of the  Portfolio  to  repurchase  at a lower  price the
interest rate futures  contract  previously sold. While the Portfolio could sell
the  long-term  debt  security and invest in a short-term  security,  this would
ordinarily  cause  the  Portfolio  to give up  income  on its  investment  since
long-term rates normally exceed short-term rates.

    OPTIONS ON FUTURES CONTRACTS.  The Common Stock,  Corporate Bond, Government
Securities and Asset Allocation Portfolios may purchase options on interest rate
futures contracts,  although these Portfolios will not write options on any such
contracts.  A futures  option  gives a  Portfolio  the right,  in return for the
premium  paid,  to  assume  a long  position  (in the  case of a call)  or short
position  (in the case of a put) in a futures  contract at a specified  exercise
price prior to the expiration of the option. Upon exercise of a call option, the
purchaser acquires a long position in the futures contract and the writer of the
option is assigned the opposite short position. In the case of a put option, the
converse  is true.  In most  cases,  however,  a  Portfolio  would close out its
position before expiration by an offsetting purchase or sale.

    The  Portfolios  would  enter  into  options on  futures  contracts  only in
connection  with  hedging  strategies.  Generally,  these  strategies  would  be
employed under the same market conditions in which a Portfolio would use put and
call options on debt securities, as described in "Options on Securities" below.

    STOCK  INDEX  FUTURES  CONTRACTS.  The  Common  Stock and  Asset  Allocation
Portfolios may purchase and sell stock index futures contracts.  A "stock index"
assigns  relative values to the common stocks included in an index (for example,
the Standard & Poor's 500 and Composite Stock Price Index or the New York

                                      B-8
<PAGE>

================================================================================

Stock Exchange  Composite  Index),  and the index fluctuates with changes in the
market  values of such  stocks.  A stock index  futures  contract is a bilateral
agreement  to  accept or make  payment,  depending  on  whether  a  contract  is
purchased  or sold,  of an amount of cash  equal to a  specified  dollar  amount
multiplied by the  difference  between the stock index value at the close of the
last trading day of the contract and the price at which the futures  contract is
originally purchased or sold.

    To the extent that  changes in the value of the Common  Stock  Portfolio  or
Asset  Allocation  Portfolio  correspond to changes in a given stock index,  the
sale of futures  contracts on that index  ("short  hedge")  would  substantially
reduce the risk to the Portfolio of a market  decline and, by so doing,  provide
an alternative to a liquidation of securities  position,  which may be difficult
to accomplish  in a rapid and orderly  fashion.  Stock index  futures  contracts
might also be sold:

1.   When a sale  of  portfolio  securities  at that  time  would  appear  to be
     disadvantageous in the long-term because such liquidation would:

    a.   Forego possible appreciation,
    b.   Create a  situation  in which  the  securities  would  be  difficult to
              repurchase, or 
    c.   Create substantial brokerage commission;

2.  When a liquidation of part of the  investment  portfolio has commenced or is
    contemplated,  but there is, in the Adviser's  determination,  a substantial
    risk of a major price decline before liquidation can be completed; or

3. To close out stock index futures purchase transactions.

    Where the Adviser anticipates a significant market or market sector advance,
the purchase of a stock index futures  contract  ("long hedge")  affords a hedge
against the  possibility of not  participating  in such advance at a time when a
Portfolio  is not fully  invested.  Such  purchases  would  serve as a temporary
substitute for the purchase of individual stocks, which may then be purchased in
an orderly  fashion.  As purchases of stock are made, an amount of index futures
contracts  which  is  comparable  to the  amount  of  stock  purchased  would be
terminated by offsetting closing sales  transactions.  Stock index futures might
also be purchased:

1.  If the Portfolio is attempting to purchase equity  positions in issues which
    it may have or is having  difficulty  purchasing at prices considered by the
    Adviser  to be fair  value  based upon the price of the stock at the time it
    qualified for inclusion in the investment portfolio, or

2. To close out stock index futures sales transactions.

    GOLD  FUTURES  CONTRACTS.  The Asset  Allocation  Portfolio  may enter  into
futures  contracts on gold. A gold futures  contract is a standardized  contract
which is traded on a regulated  commodity futures  exchange,  and which provides
for the future delivery of a specified amount of gold at a specified date, time,
and price.  When the  Portfolio  purchases a gold futures  contract,  it becomes
obligated to take  delivery  and pay for the gold from the seller in  accordance
with  the  terms  of the  contract.  When  the  Portfolio  sells a gold  futures
contract,  it becomes obligated to make delivery of the gold to the purchaser in
accordance  with the terms of the contract.  The Portfolio  will enter into gold
futures  contracts  only for the  purpose of hedging  its  holdings  or intended
holdings of gold stocks.  The Portfolio  will not engage in these  contracts for
speculation  or for  achieving  leverage.  The  hedging  activities  may include
purchases of futures  contracts as an offset  against the effect of  anticipated
increases  in the  price of gold or  sales of  futures  contracts  as an  offset
against the effect of anticipated declines in the price of gold.

    RISKS ASSOCIATED WITH FUTURES AND FUTURES  OPTIONS.  There are several risks
associated  with the use of futures  and futures  options for hedging  purposes.
While hedging  transactions may protect a Portfolio against adverse movements in
the general level of interest rates and economic  conditions,  such transactions
could also preclude the Portfolio from the opportunity to benefit from favorable
movements  in the  underlying  component.  There  can be no  guarantee  that the
anticipated  correlation  between price  movements in the hedging vehicle and in
the portfolio securities being hedged will occur. An incorrect correlation could
result in a loss on both the hedged  securities and the hedging  vehicle so that
the Portfolio's return might have been better if hedging had not been attempted.
The degree of  imperfection  of  correlation  depends on  circumstances  such as
variations  in  speculative  market  demand for  futures  and  futures  options,
including  technical  influences  in futures  trading and futures  options,  and
differences  between the financial  instruments being hedged and the instruments
underlying  the standard  contracts  available  for trading in such  respects as
interest rate levels,  maturities,  and credit-worthiness of issuers. A decision
as to  whether,  when,  and how to hedge  involves  the  exercise  of skill  and
judgment  and even a  well-conceived  hedge may be  unsuccessful  to some degree
because of market

                                      B-9
<PAGE>

================================================================================

behavior or unexpected interest rate trends.

    There can be no assurance  that a liquid  market will exist at a time when a
Portfolio  seeks to close out a futures  contract or a futures option  position.
Most  futures  exchanges  and boards of trade  limit the  amount of  fluctuation
permitted in futures  contract  prices during a single day. Once the daily limit
has been reached on a particular  contract,  no trades may be made that day at a
price beyond that limit.  The daily limit governs only price movements  during a
particular trading day and therefore does not limit potential losses because the
limit may work to prevent the liquidation of unfavorable positions. For example,
futures  prices  have  occasionally   moved  to  the  daily  limit  for  several
consecutive  trading days with little or no trading,  thereby  preventing prompt
liquidation  of positions and  subjecting  some holders of futures  contracts to
substantial losses. In addition, certain of these instruments are relatively new
and  without a  significant  trading  history.  Lack of a liquid  market for any
reason may prevent a Portfolio from liquidating an unfavorable  position and the
Portfolio  would remain  obligated to meet margin  requirements  and continue to
incur losses until the position is closed.

    A Portfolio will only enter into futures  contracts or futures options which
are  standardized  and traded on a U.S.  exchange or board of trade. A Portfolio
will not  enter  into a  futures  contract  or  purchase  a  futures  option  if
immediately thereafter the initial margin deposits for futures contracts held by
the  Portfolio  plus  premiums  paid by it for open futures  options  positions,
excluding  transactions entered into for bona fide hedging purposes and less the
amount by which any such positions are "in-the-money" (i.e., the amount by which
the value of the contract exceeds the exercise price), would exceed 5 percent of
the Portfolio's net assets.

OPTIONS ON SECURITIES

    The Common Stock, Asset Allocation, Corporate Bond and Government Securities
Portfolios may purchase put and call options on securities, and the Common Stock
and Asset  Allocation  Portfolios  may  purchase  put and call  options on stock
indices at such times as the Adviser deems  appropriate  and  consistent  with a
Portfolio's  investment  objective.   Such  Portfolios  may  also  write  listed
"covered"  calls and  "secured"  put options.  A Portfolio may write covered and
secured  options with  respect to not more than 25 percent of its net assets.  A
Portfolio  may purchase  call and put options with a value of up to 5 percent of
its net assets. Each of these Portfolios may enter into closing  transactions in
order to  terminate  its  obligations  either as a writer or a  purchaser  of an
option prior to the expiration of the option.

    PURCHASING OPTIONS ON SECURITIES. An option on a security is a contract that
gives the purchaser of the option,  in return for the premium paid, the right to
buy a specified  security  (in the case of a call option) or to sell a specified
security (in the case of a put option) from or to the seller  ("writer")  of the
option at a  designated  price  during the term of the option.  A Portfolio  may
purchase  put options on  securities  to protect  holdings in an  underlying  or
related security against a substantial  decline in market value.  Securities are
considered related if their price movements  generally correlate to one another.
For example,  the purchase of put options on debt securities held by a Portfolio
would enable a Portfolio to protect,  at least partially,  an unrealized gain in
an appreciated security without actually selling the security. In addition,  the
Portfolio would continue to receive interest income on such security.

    A Portfolio  may purchase  call  options on  securities  to protect  against
substantial  increases in prices of securities  which the  Portfolio  intends to
purchase  pending its ability to invest in such securities in an orderly manner.
A Portfolio  may sell put or call  options it has  previously  purchased,  which
could result in a net gain or loss  depending on whether the amount  realized on
the sale is more or less than the premium and other  transactional costs paid on
the option which is sold.

    WRITING  COVERED CALL AND SECURED PUT OPTIONS.  In order to earn  additional
income on its portfolio  securities or to protect  partially against declines in
the value of such securities, the Common Stock, Asset Allocation, Corporate Bond
and Government Securities Portfolios may each write "covered" call and "secured"
put  options.  The  exercise  price of a call option may be below,  equal to, or
above the current market value of the underlying security at the time the option
is  written.  During the option  period,  a covered  call  option  writer may be
assigned an exercise notice from OCC if exchanged traded requiring the writer to
deliver the underlying  security  against  payment of the exercise  price.  This
obligation  is  terminated  upon the  expiration of the option period or at such
earlier time in which the writer effects a closing purchase transaction. Closing
purchase  transactions  will  ordinarily  be  effected to realize a profit on an
outstanding call option, to prevent an underlying security from being called, to
permit the sale of the underlying security,  or to enable the Portfolio to write
another call option on the underlying  security with either a different exercise
price or expiration date or both.

================================================================================

   
partially  against  increases in the value or securities  to be  purchased,  the
Asset  Allocation,  Corporate  Bond,  Government  Securities  and  Common  Stock
Portfolios may write "secured" put options. During the option period, the writer
of a put option may be  assigned  an  exercise  notice  requiring  the writer to
purchase the underlying security at the exercise price.

    A  Portfolio  may  write a call or put  option  only if the call  option  is
"covered" or the put option is "secured" by the Portfolio.  Under a covered call
option,  the  Portfolio is  obligated,  as the writer of the option,  to own the
underlying  securities subject to the option or hold a call at an equal or lower
exercise price, for the same exercise period,  and on the same securities as the
written  call.  Under a secured put  option,  a Portfolio  must  maintain,  in a
segregated account with the Trust's custodian,  cash or liquid securities with a
value  sufficient to meet its obligation as writer of the option. A put may also
be secured if the Portfolio  holds a put on the same  underlying  security at an
equal or greater exercise price. Prior to exercise or expiration,  an option may
be  closed  out by an  offsetting  purchase  or sale of an  option  of the  same
Portfolio.
    
    OPTIONS  ON  SECURITIES  INDICES.  The  Common  Stock and  Asset  Allocation
Portfolios may purchase call and put options on securities indices. Call and put
options on  securities  indices also may be purchased or sold by a Portfolio for
the same purposes as the purchase or sale of options on  securities.  Options on
securities  indices  are  similar  to  options on  securities,  except  that the
exercise of securities index options requires cash payments and does not involve
the actual purchase or sale of securities. In addition, securities index options
are designed to reflect price  fluctuations  in a group of securities or segment
of the securities  market rather than price  fluctuations in a single  security.
The Common Stock and Asset Allocation  Portfolios may write put and call options
on securities indices.  When such options are written, the Portfolio is required
to maintain a segregated account  consisting of cash, or liquid  securities,  or
the  Portfolio  must purchase a like option of greater value that will expire no
earlier than the option  written.  The purchase of such options may not enable a
Portfolio to hedge effectively  against stock market risk if they are not highly
correlated with the value of a Portfolio's securities.  Moreover, the ability to
hedge  effectively  depends  upon the ability to predict  movements in the stock
market, which cannot be done accurately in all cases.

    RISKS OF OPTIONS TRANSACTIONS.  The purchase and writing of options involves
certain risks.  During the option period, the covered call writer has, in return
for the premium on the option,  given up the  opportunity to profit from a price
increase in the underlying  securities above the exercise price, and, as long as
its obligation as a writer  continues,  has retained the risk of loss should the
price of the underlying security decline. The writer of an option has no control
over the time when it may be required to fulfill its  obligation  as a writer of
the option.  Once an option  writer has received an exercise  notice,  it cannot
effect a closing purchase transaction in order to terminate its obligation under
the option and must deliver the underlying  securities at the exercise price. If
a put or call option  purchased by a Portfolio is not sold when it has remaining
value, and if the market price of the underlying security, in the case of a put,
remains  equal to or greater than the exercise  price or, in the case of a call,
remains less than or equal to the exercise  price,  the Portfolio  will lose its
entire  investment  in the  option.  Also,  where  a put  or  call  option  on a
particular  security is purchased to hedge against price  movements in a related
security,  the  price of the put or call  option  may move more or less than the
price of the related security.

    There can be no assurance  that a liquid  market will exist when a Portfolio
seeks to close out an option position.  Furthermore,  if trading restrictions or
suspensions  are imposed on the options  markets,  a Portfolio  may be unable to
close out a position.  If a Portfolio  cannot effect a closing  transaction,  it
will not be able to sell the  underlying  security or securities in a segregated
account while the previously written option remains outstanding,  even though it
might otherwise be advantageous to do so. Possible  reasons for the absence of a
liquid  secondary  market  on a  national  securities  exchange  could  include:
insufficient  trading  interest,  restrictions  imposed by  national  securities
exchanges,  trading  halts or  suspensions  with  respect  to  options  or their
underlying  securities,  inadequacy  of the  facilities  of national  securities
exchanges or The Options  Clearing  Corporation  due to a high trading volume or
other  events,  and a decision by one or more national  securities  exchanges to
discontinue  the trading of call  options or to impose  restrictions  on certain
types of orders.

    Since  option  premiums  paid or  received  by a  Portfolio,  as compared to
underlying  investments,  are  small in  relation  to the  market  value of such
investments,  buying and selling  put and call  options  offer large  amounts of
leverage.  Thus,  the leverage  offered by trading in options  could result in a
Portfolio's  net asset value being more sensitive to changes in the value of the
underlying securities.

FOREIGN CURRENCY TRANSACTIONS

                                      B-11
<PAGE>

================================================================================

    The Asset  Allocation  Portfolio  may enter into  foreign  currency  futures
contracts and forward currency contracts. A foreign currency futures contract is
a  standardized  contract  for the future  delivery of a  specified  amount of a
foreign currency, at a future date at a price set at the time of the contract. A
forward  currency  contract  is an  obligation  to  purchase  or sell a currency
against another currency at a future date at a price agreed upon by the parties.
The Portfolio may either accept or make delivery of the currency at the maturity
of the  contract  or,  prior  to  maturity,  enter  into a  closing  transaction
involving the purchase or sale of an  offsetting  contract.  The Portfolio  will
engage in foreign currency futures  contracts and forward currency  transactions
in  anticipation  of or to  protect  itself  against  fluctuations  in  currency
exchange rates.  The Portfolio will not commit more than 15 percent of its total
assets computed at market value at the time of commitment to a foreign  currency
futures or forward currency contracts. The Portfolio will purchase and sell such
contracts for hedging purposes and not as an investment.  The Portfolio will not
enter into a foreign currency contract with a term of greater than one year.

    Forward  currency   contracts  are  not  traded  on  regulated   commodities
exchanges. A Portfolio entering into a forward currency contract incurs the risk
of default by the counter  party to the  transaction.  There can be no assurance
that a liquid  market will exist when a  Portfolio  seeks to close out a foreign
currency futures or forward currency  position,  in which case a Portfolio might
not be able to effect a closing  purchase  transaction at any  particular  time.
While these  contracts 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 which might result should the value of such currency increase.

    Although the Asset Allocation Portfolio values assets daily in U.S. dollars,
it does not intend to physically convert its holdings of foreign currencies into
U.S.  dollars on a daily basis.  The Portfolio  will do so from time to time and
investors should be aware of the costs of currency conversion.  Although foreign
exchange  dealers do not charge a fee for  conversion,  they do realize a profit
based on the  difference  (the  "spread")  between  the prices at which they are
buying  and  selling  various  currencies.  Thus,  a dealer  may offer to sell a
foreign  currency to the Portfolio at one rate,  while offering a lesser rate of
exchange should the Portfolio desire to resell that currency to the dealer.

OPTIONS ON FOREIGN CURRENCIES

    The Asset  Allocation  Portfolio  may  invest  up to 5 percent  of its total
assets, taken at market value at the time of investment, in call and put options
on domestic and foreign  securities  and foreign  currencies.  The Portfolio may
purchase call and put options on foreign  currencies as a hedge against  changes
in the value of the U.S.  dollar (or another  currency) in relation to a foreign
currency in which portfolio  securities of the Portfolio may be  denominated.  A
call option on a foreign  currency  gives the  purchaser the right to buy, and a
put  option  the  right to sell,  a  certain  amount of  foreign  currency  at a
specified  price during a fixed  period of time.  The  Portfolio  may enter into
closing sale transactions with respect to such options, exercise them, or permit
them to expire.

    The Asset Allocation Portfolio may employ hedging strategies with options on
currencies before the Portfolio purchases a foreign security  denominated in the
hedged currency,  during the period the Portfolio holds the foreign security, or
between the day the foreign  security is purchased or sold and the date on which
payment therefor is made or received. Hedging against a change in the value of a
foreign currency in the foregoing manner does not eliminate  fluctuations in the
prices  of  portfolio  securities  or  prevent  losses  if the  prices  of  such
securities decline.  Furthermore,  such hedging  transactions reduce or preclude
the  opportunity  for gain if the value of the hedged  currency  should increase
relative to the U.S.  dollar.  The Portfolio  will  purchase  options on foreign
currencies  only for  hedging  purposes  and will not  speculate  in  options on
foreign  currencies.  The  Portfolio  may invest in options on foreign  currency
which  are  either  listed  on a  domestic  securities  exchange  or traded on a
recognized foreign exchange.

    An option  position  on a  foreign  currency  may be  closed  out only on an
exchange  which  provides a secondary  market for an option of the same  series.
Although the Asset  Allocation  Portfolio  will  purchase  only  exchange-traded
options,  there is no assurance  that a liquid  secondary  market on an exchange
will exist for any particular option, or at any particular time. In the event no
liquid  secondary  market  exists,  it might not be possible  to effect  closing
transactions  in  particular  options.  If the  Portfolio  cannot  close  out an
exchange-traded  option which it holds,  it would have to exercise its option in
order to realize any profit and would incur  transactional  costs on the sale of
the underlying assets.

BORROWING

    For temporary purposes, such as to facilitate  redemptions,  a Portfolio may
borrow money from a bank, but only if immediately after each such

                                      B-12
<PAGE>

================================================================================

borrowing and continuing  thereafter the Portfolio  would have asset coverage of
300 percent.  Leveraging by means of borrowing will exaggerate the effect of any
increase or decrease in the value of portfolio  securities on a Portfolio's  net
asset value;  money  borrowed  will be subject to interest and other costs which
may or may not exceed the income  received from the  securities  purchased  with
borrowed  funds.  The use of borrowing  tends to result in a faster than average
movement,  up or  down,  in the net  asset  value  of a  Portfolio's  shares.  A
Portfolio  also  may  be  required  to  maintain  minimum  average  balances  in
connection with such borrowing or to pay a commitment or other fee to maintain a
line of  credit;  either  of  these  requirements  would  increase  the  cost of
borrowing over the stated interest rate.

INVESTMENT IN SECURITIES OF OTHER INVESTMENT COMPANIES

    Each Portfolio (except the Money Market  Portfolio) may purchase  securities
of other investment companies.  Such securities have the potential to appreciate
as do any other securities, but tend to present less risk because their value is
based on a diversified portfolio of investments.  The 1940 Act expressly permits
mutual funds such as the Trust to invest in other  investment  companies  within
prescribed  limitations.  An investment  company may invest in other  investment
companies if at the time of such investment (1) it does not purchase more than 3
percent of the voting securities of any one investment company,  (2) it does not
invest more than 5 percent of its assets in any single investment  company,  and
(3) the  investment in all  investment  companies  does not exceed 10 percent of
assets. Each Portfolio will comply with all of these limitations with respect to
the purchase of securities issued by other investment companies.

    Investment  companies in which the Portfolios may invest charge advisory and
administrative  fees and may also assess a sales load and/or  distribution fees.
Therefore,  investors in a Portfolio that invested in other investment companies
would  indirectly bear costs  associated  with those  investments as well as the
costs  associated  with investing in the Portfolio.  The percentage  limitations
described  above  significantly  limit  the  costs  a  Portfolio  may  incur  in
connection with such investments.

================================================================================

INVESTMENT RESTRICTIONS

    The Trust has adopted the following  restrictions  and policies  relating to
the  investment  of assets of the  Portfolios  and their  activities.  These are
fundamental  policies and may not be changed without the approval of the holders
of a "majority" of the outstanding shares of each Portfolio affected.  Under the
1940 Act,  the vote of such a  "majority"  means the vote of the  holders of the
lesser of (i) 67 percent of the  shares  represented  at a meeting at which more
than 50 percent of the  outstanding  shares are represented or (ii) more than 50
percent  of the  outstanding  shares.  A change  in  policy  affecting  only one
Portfolio  may be effected  with the approval of the holders of a "majority"  of
the outstanding shares of such Portfolio.  The Trust may not, and each Portfolio
may not (except as noted):

1.  Purchase  securities  on  margin  or  sell  securities  short,  except  that
    Portfolios  engaged in  transactions  in  options,  futures,  and options on

broker-dealers  meeting certain  guidelines for  creditworthiness,  (b) that are

bank, broker or dealer.


PORTFOLIO TURNOVER AND SECURITIES TRANSACTIONS

A portfolio turnover rate is, in general,  the percentage computed by taking the
lesser  of  purchases  or  sales  of  portfolio  securities  (excluding  certain
short-term  securities) for a year and dividing it by the monthly average of the
market value of such securities during the year. The Money Market Portfolio does
not have a stated  portfolio  turnover matrix as securities of the type in which
it invests are excluded in the usual  calculation  of that rate.  The  remaining
Portfolios do not have a  predetermined  rate of portfolio  turnover  since such
turnover will be incidental to transactions taken with a view to achieving their
respective objectives.
   
    High  turnover  and  short-term  trading  involve   correspondingly  greater
commission expenses and transaction costs.
    
    The Adviser is responsible  for decisions to buy and sell securities for the
Trust,  broker-dealer  selection, and negotiation of brokerage commission rates.
The Adviser's primary  consideration in effecting a securities  transaction will
be execution at the most favorable  price. A substantial  portion of the Trust's
portfolio  transactions  in fixed  income  securities  will be  transacted  with
primary  market  makers  acting as principal  on a net basis,  with no brokerage
commissions being paid by the Trust. In certain instances,  the Adviser may make
purchases of underwritten  issues at prices which include  underwriting fees. In
selecting a broker-dealer  to execute each particular  transaction,  the Adviser
will take the following into  consideration:  the best net price available;  the
reliability,  integrity and financial  condition of the  broker-dealer;  and the
size of contribution of the  broker-dealer to the investment  performance of the
Trust on a  continuing  basis.  The  Adviser  shall not be deemed to have  acted
unlawfully  or to have  breached  any duty  created by the  Investment  Advisory
Agreement  in question or  otherwise  solely by reason of its having  caused the
Trust to pay a broker-dealer  that provides  brokerage and research  services to
the  Adviser  an amount of  commission  for  effecting  a  portfolio  investment
transaction in excess of the amount of commission  another  broker-dealer  would
have charged for effecting that transaction,  if the Adviser  determines in good
faith that such amount of commission  was reasonable in relation to the value of
the brokerage and research  services provided by such  broker-dealer,  viewed in
terms  of  either  that   particular   transaction  or  the  Adviser's   overall
responsibilities  with respect to its clients.  The Adviser allocates the orders
placed  by it on behalf of the  Trust to such  broker-dealers  who also  provide
research or statistical material, or other services to the Trust, the Adviser or
its clients.  Such  allocation  shall be in such amounts and  proportions as the
Adviser  shall  determine  and the  Adviser  will  report  on  said  allocations
periodically to the Trust indicating the broker-dealers to whom such allocations
have  been made and the  basis  therefor.  Broker-dealers  may be  selected  who
provide  brokerage  and/or research  services to the Trust and/or other accounts
over which the  Adviser  exercises  investment  discretion.  Such  services  may
include  advice  concerning  the  value  of  securities   (including   providing
quotations as to securities);  the  advisability of investing in,  purchasing or
selling securities;  the availability of securities or the purchasers or sellers
of securities;  furnishing analysis and reports concerning issuers,  industries,
securities,  economic factors and trends,  portfolio strategy and performance of
accounts;  and  effecting  securities   transactions  and  performing  functions
incidental thereto, such as clearance and settlement.
   
    The receipt of research from  broker-dealers may be useful to the Adviser in
rendering investment management services to the Trust and/or the Adviser's other
clients;  conversely,  such  information  provided  by  broker-dealers  who have
executed  transaction  orders on behalf  of other  clients  may be useful to the
Adviser  in  carrying  out its  obligations  to the Trust.  The  receipt of such
research will not be substituted for the independent research of the Adviser. It
does enable the Adviser to reduce costs to less than those which would have been
required to develop  comparable  information  through its own staff.  The use of
broker-dealers  who  supply  research  may  result  in  the  payment  of  higher
commissions  (including  mark-ups or mark-downs on principal  transactions) than
those  available  from other  broker-dealers  who provide only the  execution of
portfolio transactions. Orders on behalf of the Trust may be bunched with orders
on behalf of other  clients  of the  Adviser.  During  the  fiscal  years  ended
December  31,  1997,  1996,  and  1995,  $1,075,944,   $588,876,  and  $387,644,
respectively, were paid in brokerage commissions to brokers.
    
    The Board of Trustees  periodically reviews the Adviser's performance of its
responsibilities  in connection with the placement of portfolio  transactions on
behalf of the Trust.

NET ASSET VALUES OF THE SHARES OF THE PORTFOLIOS

THE VALUE OF THE SECURITIES OF THE MONEY MARKET PORTFOLIO

    The Money Market Portfolio's use of the amortized cost method is conditioned
on compliance with certain conditions  contained in Rule 2a-7 (the "Rule") under
the  1940  Act.  The  Rule  also  obligates  the  Trustees,  as  part  of  their
responsibility  within the  overall  duty of care owed to the  shareholders,  to
establish  procedures  reasonably  designed,  taking into account current market
conditions and the Portfolio's investment objectives, to stabilize the net asset
value per share as computed for the purpose of  distribution  and  redemption at
$1.00 per share. The Trustees'  procedures include periodically  monitoring,  as
they  deem  appropriate  and at such  intervals  as are  reasonable  in light of
current market conditions, the relationship between the amortized cost value per
share and the net asset  value per share  based upon  available  indications  of
market value.  The Trustees will consider what steps should be taken, if any, in
the event of difference of more than one-half of one percent between the two. To
minimize any material  dilution or other unfair  results  which might arise from
differences  between the two, the Trustees will take such steps as they consider
appropriate  (e.g.,  redemption  in kind or  shortening  the  average  portfolio
maturity).

    It is the normal  practice of the Money Market  Portfolio to hold  portfolio
securities  to  maturity.  Therefore,  unless a sale or other  disposition  of a
security  is  mandated  by  redemption   requirements  or  other   extraordinary
circumstances,  the Portfolio will realize the principal amount of the security.
Under the amortized cost method of valuation, neither the amount of daily income
nor  the  net  asset  value  is  affected  by  any  unrealized  appreciation  or
depreciation of the Portfolio. In periods of declining interest rates, the yield
on shares of the  Portfolio  will tend to be higher than if the  valuation  were
based upon market prices and estimates. In periods of rising interest rates, the
yield on shares of the Portfolio will tend to be lower than if the valuation was
based upon market prices and estimates.

THE VALUE OF THE SECURITIES OF THE OTHER PORTFOLIOS

    Securities held by all Portfolios  except the Money Market Portfolio will be
valued as follows:  Portfolio securities which are traded on stock exchanges are
valued  at the last  sale  price  as of the  close  of  business  on the day the
securities  are being  valued,  or lacking  any sales,  at the mean  between the
closing bid and asked prices.  Securities traded in the over-the-counter  market
are valued at the mean between the bid and asked prices or yield  equivalent  as
obtained from one or more dealers that make markets in the securities. Portfolio
securities which are traded both in the  over-the-counter  market and on a stock
exchange are valued  according to the broadest and most  representative  market,
and it is  expected  that  for  debt  securities  this  ordinarily  will  be the
over-the-counter  market.  Securities and assets for which market quotations are
not readily available are valued at fair value as determined in good faith by or
under  the  direction  of the  Board  of  Trustees  of  the  Trust.  In  valuing
lower-rated  debt  securities,  it should be recognized  that  judgment  plays a
greater  role than is the case with  respect to  securities  for which a broader
range of  dealer  quotations  and  last  sale  information  is  available.  Debt
securities  with  maturities  of sixty (60) days or less are valued at amortized
cost.

GENERAL

    The  Trustees  themselves  have the power to alter the  number  and terms of
office of the  Trustees,  and they may at any time  lengthen  their own terms or
make their terms of unlimited  duration (subject to certain removal  procedures)
and appoint  their own  successors,  provided that always at least a majority of
the Trustees  have been  elected by the  shareholders  of the Trust.  The voting
rights of  shareholders  are not  cumulative,  so that  holders  of more than 50
percent of the shares  voting  can, if they  choose,  elect all  Trustees  being
selected, while the holders of the remaining shares would be unable to elect any
Trustees.  The Trust is not required to hold Annual Meetings of Shareholders for
action by  shareholders'  vote  except as may be required by the 1940 Act or the
Declaration of Trust.  The Declaration of Trust provides that  shareholders  can
remove Trustees by a vote of two-thirds of the vote of the  outstanding  shares.
The  Trustees  will call a meeting of  shareholders  to vote on the removal of a
Trustee  upon the  written  request of the  holders of 10 percent of the Trust's
shares.  In addition,  10 or more  shareholders  meeting certain  conditions and
holding  the lesser of  $25,000  worth or 1 percent  of the  Trust's  shares may
advise  the  Trustees  in  writing  that they  wish to  communicate  with  other
shareholders  for the purpose of  requesting a meeting to remove a Trustee.  The
Trustees will then either give those shareholders access to the shareholder list
or, if requested by those  shareholders,  mail at the shareholders'  expense the
shareholders'  communication  to all other  shareholders.  See the  Contract and
Policy Prospectuses for information as to the voting of shares by Owners.

================================================================================

    Each  issued  and  outstanding  share  of  each  Portfolio  is  entitled  to
participate  equally in dividends and distributions of the respective  Portfolio
and in the  net  assets  of  such  Portfolio  upon  liquidation  or  dissolution
remaining  after  satisfaction  of outstanding  liabilities.  The shares of each
Portfolio  have no  preference,  preemptive,  conversion,  exchange  or  similar
rights, and are freely transferable.

    Under Rule 18f-2 under the 1940 Act, as to any investment  company which has
two or more series  (such as the  Portfolios)  outstanding  and as to any matter
required to be submitted to shareholder  vote, such matter is not deemed to have
been  effectively  acted upon unless approved by the holders of a "majority" (as
defined in that Rule) of the voting  securities  of each series  affected by the
matter.  Such  separate  voting  requirements  do not apply to the  election  of
Trustees or the ratification of the selection of accountants.  The Rule contains
special provisions for cases on which an advisory contract is approved by one or
more, but not all, series.  A change in investment  policy may go into effect as
to one or more  series  whose  holders so approve  the  change  even  though the
required vote is not obtained as to the holders of other affected series.

    Under  Massachusetts  law,  shareholders  of a trust  such as the Trust may,
under  certain  circumstances,  be held  personally  liable as partners  for the
obligations of the Trust. The Declaration of Trust, however, contains an express
disclaimer of  shareholder  liability for acts or  obligations  of the Trust and
requires that notice of such disclaimer be given in each  agreement,  obligation
or  instrument  entered  into or  executed  by the  Trust or its  Trustees.  The
Declaration of Trust provides for  indemnification and reimbursement of expenses
out of  Trust  property  for any  shareholder  held  personally  liable  for its
obligations.  The Declaration of Trust also provides that the Trust shall,  upon
request,  assume the defense of any claim made against any  shareholder  for any
act or obligation  of the Trust and satisfy any judgment  thereon.  Thus,  while
Massachusetts  law permits a shareholder of a trust such as the Trust to be held
personally  liable  as a  partner  under  certain  circumstances,  the risk of a
Contract Owner incurring  financial loss on account of shareholder  liability is
highly unlikely and is limited to the relatively  remote  circumstances in which
the Trust would be unable to meet its obligations.

    The  Declaration  of Trust  further  provides  that the Trustees will not be
liable for errors of judgment  or  mistakes  of fact or law,  but nothing in the
Declaration of Trust protects a Trustee  against any liability to which he would
otherwise  be  subject  by reason  of  willful  misfeasance,  bad  faith,  gross
negligence,  or reckless  disregard of the duties involved in the conduct of his
office.

    The Trust  and the  Adviser  have  Codes of Ethics  governing  the  personal
securities  transactions  of officers and  employees.  These codes require prior
approval for certain transactions and prohibit  transactions which may be deemed
to conflict with the securities trading of the Adviser's clients.

Board of Trustees
Conseco Series Trust

Re:      Conseco Series Trust
         Registration Statement on Form N-1A

Gentlemen and Madam:

     I am Executive Vice  President,  Secretary and General  Counsel of Conseco,
Inc.,  the direct owner of the  investment  adviser of Conseco Series Trust (the
"Registrant").  At your  request,  I have  examined or caused to be examined the
Registration  Statement  on Form N-1A,  (the  "Registration  Statement")  of the
Registrant  with  respect  to the  securities  issued  in  connection  with  the
Registrant   offering  shares  to  insurance  company  separate  accounts.   The
Registrant's  Form  N-1A  Registration   Statement  is  filed  pursuant  to  the
Securities Act of 1933 (the "Act") and the Investment Company Act of 1940 ("1940
Act").  This opinion is being  furnished  pursuant to the Act in connection with
the Registrant's Form N-1A Registration Statement.

     In rendering this opinion,  I, or attorneys under my supervision  (together
referred  to  herein as  "we"),  have  examined  and  relied  upon a copy of the
Registration  Statement. We have also examined originals, or copies of originals
certified to our satisfaction, of such agreements,  documents,  certificates and
statements of government officials and other instruments, and have examined such
questions of law and have satisfied  ourselves as to such matters of fact, as we
have  considered  relevant and  necessary as a basis for this  opinion.  We have
assumed the  authenticity  of all documents  submitted to us as  originals,  the
genuineness of all signatures, the legal capacity of all natural persons and the
conformity with the original documents of any copies thereof submitted to us for
examination.

     Based on the foregoing,  and subject to the  qualifications and limitations
hereinafter set forth, I am of the opinion that:

         1.   The Registrant has been duly organized and is an existing business
              trust   pursuant   to  the   applicable   laws  of  the  State  of
              Massachusetts;

         2.   The  Account  is  a  open  ended  management   investment  company
              registered under the 1940 Act; and

         3.   The securities issued by the Registrant,  when issued as described
              in the  Registration  Statement,  will be duly authorized and upon
              issuance will be validly issued, fully paid and non-assessable.

     I do not find it necessary  for the purposes of this opinion to cover,  and
accordingly  I express no opinion as to, the  application  of the  securities or
blue  sky  laws  of the  various  states  to the  sale of the  securities  to be
registered  pursuant  to  the  Registration  Statement.   Without  limiting  the
generality of the foregoing, I express no opinion in connection with the matters
contemplated  by the  Registration  Statement,  and no opinion may be implied or
inferred, except as expressly set forth herein.

     This  opinion is  limited  to the laws of the State of  Indiana  and of the
United  States of  America to the extent  applicable.  If any of the  securities
included in the Registration Statement are governed by the laws of a state other
than  Indiana,  I have assumed for the purposes of this opinion that the laws of
such other state are the same as those of the State of Indiana.

     I hereby  consent to the  inclusion  of the opinion as Exhibit  B-10 to the
Registration Statement and to all references to me in the Registration Statement
or the Prospectus included therein.

Very truly yours,

/S/ JOHN J. SABL

John J. Sabl
Executive Vice President, Secretary,
and General Counsel



                                                                    Exhibit (11)

                       CONSENT OF INDEPENDENT ACCOUNTANTS

     We consent  to the  inclusion  in  Post-Effective  Amendment  No. 22 to the
Registration  Statement of Conseco Series Trust (the "Trust") on Form N-1A (File
No.  2-80455)  of our  report  dated  February  23,  1998,  on our  audit of the
financial  statements  and financial  highlights  of the Trust,  which report is
included in the Annual Report to  Shareholders  for the year ended  December 31,
1997, which is incorporated by reference in the Post-Effective  Amendment to the
Registration  Statment.  We also consent to the  reference to our Firm under the
caption "Independent Accountants."
