                                MONEY MARKET FUND

INVESTMENT OBJECTIVE
What is this fund's goal?

The Money  Market Fund seeks high current  income from money market  instruments
consistent with the  preservation of capital and liquidity.  The fund intends to
maintain a stable value of $1.00 per share.

INVESTOR PROFILE
Who should consider investing in this fund?

You may want to invest more of your assets in this fund if you:

     1.   require stability of principal;
     2.   are seeking a mutual fund for the cash portion of an asset  allocation
          program;
     3.   need to "park" your money temporarily; or
     4.   consider yourself a saver rather than an investor.

You may want to invest fewer of your assets in this fund if you:

     1.   want federal deposit insurance;
     2.   are seeking an investment that is likely to outpace inflation;
     3.   are investing for retirement or other goals that are many years in the
          future; or
     4.   are investing for growth or maximum current income.

PRINCIPAL RISKS
What are the main risks of investing in this fund?

   
As with any money market fund, the yield paid by the fund will vary with changes
in interest rates. Generally, if interest rates rise, the market value of income
bearing  securities will decline.  There is a possibility  that the fund's share
value could fall below $1.00,  which could reduce the value of your account.  An
investment  in the Money Market Fund is neither  insured nor  guaranteed  by the
Federal Deposit Insurance  Corporation or any other government agency.  Although
the Money  Market Fund  attempts to maintain a stable  price of $1.00 per share,
there is no  assurance  that it will be able to do so and it is possible to lose
money by investing in the fund.
    

PRINCIPAL INVESTMENT STRATEGIES
How does this fund pursue its objective?

   
The Money  Market Fund  invests  exclusively  in U.S.  dollar-denominated  money
market securities  maturing (or resetting their interest rates to market levels)
in thirteen  months or less from the date of  purchase.  It includes  securities
issued by U.S. and foreign financial  institutions,  corporate issuers, the U.S.
Government  and its  agencies  and  instrumentalities,  municipalities,  foreign
governments,  and multi-national  organizations such as the World Bank. At least
95% of the fund's  assets must be rated in the highest  short-term  category (or
its  unrated  equivalent),  and 100% of the fund's  assets  must be  invested in
securities  rated  in  the  two  highest  rating  categories.  A  more  detailed
description  of the  types of  permissible  issuers  and  rating  categories  is
contained in the SAI. The fund  maintains a  dollar-weighted  average  portfolio
maturity of 90 days or less. The fund may also invest in U.S. dollar-denominated
foreign money market securities,  although no more than 25% of the fund's assets
may be invested  in these  securities  unless  they are backed by a U.S.  parent
financial institution.

Please  remember that past  performance is no guarantee of the results the Money
Market  Fund may achieve in the  future.  Future  returns may be higher or lower
than the returns the fund achieved in the past.

How does the  performance  of the Money  Market  Fund  compare to general  money
market returns?

   
The  following  table  compares  the  performance  of  Class Z  Shares  with the
performance  of the  90-day  U.S.  Treasury  Bill,  which is one  measure of the
performance of the relevant market.  Returns shown for the Money Market Fund are
after the deduction of fund management and operating expenses. The Treasury Bill
returns bear no such expenses.

                               TREASURY 2000 FUND


INVESTMENT OBJECTIVE
What is this fund's goal?

The  Treasury  2000 Fund seeks to provide  safety of  capital  and a  relatively
predictable payout upon portfolio maturity.

INVESTOR PROFILE
Who should consider investing in this fund?

You may want to invest more of your assets in this fund if you:

     1.   desire an assured  future value of a portion of your  investments at a
          specified future date; or
     2.   prefer the very high credit quality of U. S. Treasury securities.

You may want to invest fewer of your assets in this fund if you:

     1.   want Federal deposit insurance;
     2.   are willing to assume some variability of future balance in pursuit of
          higher long term returns; or
     3.   want an investment based on growth or maximum current income.

PRINCIPAL RISKS
What are the main risks of investing in this fund?

   
Because  of their  substantial  discount  from face  value,  prices of  Stripped
Treasury Securities are particularly sensitive to changes in interest rates. The
longer the term to maturity,  the more susceptible these securities will be to a
given change in interest rates (interest rate risk).

Variable  rates of inflation and economic  growth,  together with the fiscal and
monetary  policies  adopted to  attempt  to deal with  these and other  economic
problems,  contribute to wide  fluctuations  in interest  rates (and thus in the
value of  fixed-rate  debt  obligations  like these).  Although  more  volatile,
Stripped  Treasury  Securities avoid  reinvestment  risk of interest payments at
inopportune  times in the market.  Avoiding this risk is an important  factor in
being able to achieve a relatively predictable payout upon portfolio maturity.
    

PRINCIPAL INVESTMENT STRATEGIES
How does this fund pursue its objective?

   
The  Treasury  2000 Fund  invests  primarily  in Stripped  Treasury  Securities.
Stripped Treasury  Securities include U.S. Treasury debt obligations  originally
issued as bearer  bonds  which have been  stripped of their  unmatured  interest
coupons.  Stripped  Treasury  Securities do not receive any periodic payments of
interest  and are  not  subject  to  early  redemption.  The  Stripped  Treasury
Securities held by this fund mature on November 15, 2000.
    

Unlike most  coupon-bearing  bonds,  Stripped Treasury  Securities are sold at a
substantial  discount from face value because the buyer  receives only the right
to receive one future fixed  payment and does not receive any rights to periodic
interest payments. While Stripped Treasury Securities insulate shareholders from
being unable to invest interest payments received at a rate as high as the yield
to maturity on the stripped  security,  they also prevent investing the interest
at a higher rate should interest rates rise.

   
In  addition  to  Stripped  Treasury   Securities,   this  fund  may  invest  in
coupon-bearing Treasury Notes with maturities identical to those of the Stripped
Treasury  Securities held in the portfolio.  The Treasury Notes may be purchased
to the extent  necessary to maintain  sufficient cash flow to pay the investment
adviser's fees.

On or within 12 months prior to November 15, 2000,  the  securities  held by the
Fund will be liquidated. Once the Fund has liquidated its portfolio,  additional
Stripped  Treasury  Securities  with a portfolio  maturity date selected at that
time may be purchased and the Fund may continue, with liquidation and subsequent
refunding  occurring  from  time to  time.  If,  at the  time  of the  portfolio
liquidation date for this Fund, it appears not to be in the best interest of the
Fund  to  purchase  additional  Stripped  Treasury  Securities,  the  fund  will
distribute its assets and cease operations.

                                    BOND FUND

INVESTMENT OBJECTIVE
What is this fund's goal?
    

The Bond Fund seeks to generate a high level of current income,  consistent with
the prudent  limitation of investment risk,  primarily  through  investment in a
diversified portfolio of income bearing debt securities.

INVESTOR PROFILE
Who should consider investing in this fund?

You may want to invest more of your assets in this fund if you:

     1.   seek an investment based on a regular stream of income;
     2.   seek higher potential  returns than money market funds and are willing
          to accept moderate risk of volatility;
     3.   want to diversify your investments;
     4.   seek a  mutual  fund for the  income  portion  of an asset  allocation
          program; or
     5.   are retired or nearing retirement.

You may want to invest fewer of your assets in this fund if you:

     1.   invest for maximum return over a long time horizon; or
     2.   need absolute stability of your principal.

PRINCIPAL RISKS
What are the main risks of investing in this fund?

As with most income funds,  the Bond Fund is subject to interest rate risk,  the
risk that the value of your  investment  will fluctuate with changes in interest
rates.  Typically, a rise in interest rates causes a decline in the market value
of income  bearing  securities.  Other  factors may affect the market  price and
yield of the fund's  securities,  including  investor  demand and  domestic  and
worldwide  economic  conditions.  Loss of money is a risk of  investing  in this
fund.

In addition,  the fund is subject to credit risk,  the risk that issuers of debt
securities may be unable to meet their interest or principal payment obligations
when  due.  The  ability  of the  fund  to  realize  interest  under  repurchase
agreements  and pursuant to loans of the fund's  securities  is dependent on the
ability of the seller or borrower, as the case may be, to perform its obligation
to the fund. There is also prepayment/extension risk, which is the chance that a
rise or fall in interest rates will  reduce/extend the life of a mortgage-backed
security by increasing/decreasing  mortgage prepayments,  reducing the return in
either case.

To the extent that the fund invests in non-investment grade securities, the fund
is also subject to  above-average  credit,  market and other  risks.  Issuers of
non-investment  grade  securities  (i.e.,  "junk"  bonds) are  typically in weak
financial  health and their  ability to pay interest and principal is uncertain.
Compared to issuers of investment-grade bonds, they are more likely to encounter
financial  difficulties and to be materially affected by these difficulties when
they do encounter them.

PRINCIPAL INVESTMENT STRATEGIES
How does this fund pursue its objective?

To keep current income  relatively  stable and to limit share price  volatility,
the  Bond  Fund  emphasizes   investment   grade  securities  and  maintains  an
intermediate  (typically  3-6 year)  average  portfolio  duration.  Under normal
circumstances,  the fund invests at least 80% of its assets in:

     1.   Corporate debt securities:  securities  issued by domestic and foreign
          corporations;
     2.   U.S.  government debt securities:  securities  issued or guaranteed by
          the U.S. government or its agencies or
   
          instrumentalities; and
     3.   Foreign government debt securities: securities issued or guaranteed by
          a foreign government or its agencies or instrumentalities,  payable in
          U.S. dollars.
    

To the extent  permitted by law and  available in the market,  the fund may also
invest  in  asset-backed  and   mortgage-backed   securities,   including  those
representing mortgage, commercial or consumer loans originated by credit unions.

                                  BALANCED FUND

INVESTMENT OBJECTIVE
What is this fund's goal?

The Balanced Fund seeks a high total return  through the  combination  of income
and capital appreciation.

INVESTOR PROFILE
Who should consider investing in this fund?

You may want to invest more of your assets in this fund if you:

     1.  are looking for a more conservative option to a growth-oriented fund;
     2.  want a well-diversified and relatively stable investment allocation;
     3.  need a core investment;
     4.  seek a reasonable total return over the long term  irrespective of its
         form (i.e., capital gains or ordinary income); or
     5.  are retired or nearing retirement.

You may want to invest fewer of your assets in this fund if you:

     1.  are investing for maximum return over a long time horizon;
     2.  want your return to be either  ordinary  income or capital gains,  but
         not both; or
     3.  require a high degree of stability of your principal.

PRINCIPAL RISKS
What are the main risks of investing in this fund?

   
The risks of this fund are similar to the risks  described  for the Bond,  Money
Market,  Growth and Income Stock and Capital Appreciation Stock Funds because it
invests in the same types of securities. As with any fund that invests in stocks
and bonds, the fund is subject to market and interest rate risks, the risks that
the value of your investment will fluctuate in response to stock and bond market
movements and changes in interest rates.

Generally, if interest rates rise, the market value of income bearing securities
(including bonds) will decline.  There is also the risk that the issuer will not
pay its debts. If payments on an income bearing  security are not paid when due,
it may cause the net asset value of the fund to go down.

Because  different stocks and bonds move in and out of favor depending on market
conditions,  investor  sentiment  and a  myriad  of other  issues,  the fund may
sometimes  outperform funds with a different  investment objective and sometimes
underperform them. Loss of money is a risk of investing in this fund.
    

PRINCIPAL INVESTMENT STRATEGIES
How does this fund pursue its objective?

   
The Balanced Fund invests in a broadly diversified array of securities including
common  stocks,  bonds and money market  instruments.  The fund employs  regular
rebalancing to maintain a relatively  static asset  allocation.  Stock, bond and
cash  components  will vary,  however,  reflecting the relative  availability of
attractively  priced stocks and bonds.  Generally,  however,  common stocks will
constitute 60% to 40% of the fund's assets,  bonds will constitute 40% to 60% of
the fund's assets and money market  instruments  may constitute up to 20% of the
fund's  assets.  The  Balanced  Fund will invest  primarily in the same types of
equity securities in which the Capital  Appreciation Stock and Growth and Income
Stock Funds invest, the same types of bonds in which the Bond Fund invests,  and
the same  types of money  market  instruments  in which  the Money  Market  Fund
invests.
    

The fund may invest up to 25% of its assets in foreign securities.

   
The fund typically sells a stock when the fundamental expectations for buying it
no longer apply,  the price  exceeds its perceived  value or other stocks appear
more attractively priced relative to their values.

                          GROWTH AND INCOME STOCK FUND

INVESTMENT OBJECTIVE
What is this fund's goal?

The Growth and Income Stock Fund seeks long-term capital growth,  with income as
a secondary consideration.

INVESTOR PROFILE
Who should consider investing in this fund?

You may want to invest more of your assets in this fund if you:

     1.   are  looking  for a  stock  fund  that  has  both  growth  and  income
          components;
     2.   are looking for a more conservative option to a growth-oriented fund;
     3.   need a core investment;
     4.   seek  above-average  long-term  total return  through a combination of
          capital gains and ordinary income; or
     5.   are retired or nearing retirement.

You may want to invest fewer of your assets in this fund if you:

     1.   are investing for maximum return over a long time horizon;
     2.   desire your return to be either ordinary income or capital gains,  but
          not both; or
     3.   require a high degree of stability of your principal.

PRINCIPAL RISKS
What are the main risks of investing in this fund?

   
Any fund that  invests  in stocks  and seeks  income is  subject  to market  and
interest rate risks,  meaning the value of your  investment  will fluctuate when
the stock market and interest  rates move.  Loss of money is a risk of investing
in this fund.

In addition,  a "value"  approach to investing  includes the risks that:  1. the
securities   markets  will  not  recognize  the  value  of  a  security  for  an
unexpectedly  long  period  of  time;  and 2. a  stock  that is  believed  to be
undervalued actually is appropriately priced or over-priced due to unanticipated
problems associated with the issuer or industry.

The  fund may  carry  additional  risks  relating  to  foreign  securities.  The
principal risks of foreign securities are described later in this prospectus and
in the SAI.
    

PRINCIPAL INVESTMENT STRATEGIES
How does this fund pursue its objective?

The  Growth  and  Income  Fund will  focus on stocks  of larger  companies  with
financial and market strengths and a long-term record of financial  performance.
Under  normal  market  conditions,  the fund will  maintain  at least 80% of its
assets in these stocks.  Primarily through ownership of a diversified  portfolio
of common stocks and securities  convertible  into common stocks,  the fund will
seek a rate of  return  in  excess  of  returns  typically  available  from less
variable investment alternatives.  The fund generally follows what is known as a
"value"  approach,  which  generally  means that the managers  seek to invest in
stocks at prices below their  estimated  value based on fundamental  analysis of
the issuing  company and its prospects.  By investing in value stocks,  the fund
attempts to limit the downside risk over time but may also produce smaller gains
than other stock funds if their values are not realized by the market.

The fund will typically  invest in securities  representing  every sector of the
S&P 500 in about (+/-50%) the same weightings as such sector has in the S&P 500.
For example, if technology companies represent 10% of the S&P 500, the fund will
typically have between 5% and 15% of its assets invested in securities issued by
technology companies.

The fund may also  invest in  warrants,  preferred  stocks  and debt  securities
(including non-investment grade debt securities).  The fund may invest up to 25%
of its assets in foreign securities.

The fund typically sells a stock when the fundamental expectations for buying it
no  longer  apply,  the price  exceeds  its value or other  stocks  appear  more
attractively priced relative to their values.

INVESTMENT OBJECTIVE
What is this fund's goal?

The Capital Appreciation Stock Fund seeks long-term capital appreciation.

INVESTOR PROFILE
Who should consider investing in this fund?

You may want to invest more of your assets in this fund if you:

   
     1.   have a longer investment time horizon;
    
     2.   are  willing  to  accept  higher  on-going  short-term  risk  for  the
          potential of higher long-term returns;
     3.   want to diversify your investments;
     4.   are  seeking  a fund for the  growth  portion  of an asset  allocation
          program; or
     5.   are investing for retirement or other goals that are many years in the
          future.

You may want to invest fewer of your assets in this fund if you:

     1.   are investing with a shorter investment time horizon in mind;
   
     2.   are seeking an investment  based on income rather than capital  gains;
          or
    
     3.   are   uncomfortable   with  an   investment   whose   value  may  vary
          substantially.

PRINCIPAL RISKS
What are the main risks of investing in this fund?

   
As with any fund that  invests  in equity  securities,  this fund is  subject to
market  risk,  the risk that the value of a security may move up and down due to
factors not directly related to the issuer.  Loss of money is a significant risk
of investing  in this fund.  Due to its focus on stocks that may  appreciate  in
value and lack of emphasis on those that provide current income,  this fund will
typically  experience  greater  volatility  over time than the Growth and Income
Stock Fund.

In addition,  a "value"  approach to investing  includes the risks that:  1. the
securities   markets  will  not  recognize  the  value  of  a  security  for  an
unexpectedly  long  period  of  time;  and 2. a  stock  that is  believed  to be
undervalued actually is appropriately priced or over-priced due to unanticipated
problems associated with the issuer or industry.

To the extent  that the fund  invests  in  higher-risk  securities,  it takes on
additional risks that could adversely affect its  performance.  For example,  to
the extent that the fund  invests in foreign  securities,  it will be subject to
the risks related to such securities,  including the risks of adverse changes in
the rate of currency exchange and associated  unstable political  situations.  A
further  discussion of the principal risks associated with foreign securities is
contained in the foreign securities section and SAI. To the extent that the fund
invests  in  higher-risk  securities,  it takes on  additional  risks that could
adversely  affect its  performance.  For  example,  to the extent  that the fund
invests in foreign  securities,  it will be subject to the risks related to such
securities,  including the risks of changes in the rate of currency exchange and
varying  political  situations.  The principal  risks of foreign  securities and
small company stocks are described later in this prospectus and in the SAI.

PRINCIPAL INVESTMENT STRATEGIES
How does this fund pursue its objective?
    

The  Capital  Appreciation  Stock Fund  invests  primarily  in common  stocks of
companies of various sizes, and will, under normal market  conditions,  maintain
at least 80% of its assets in such  securities.  The fund seeks stocks that have
low market  prices  relative  to their  values  based on  analysis by the fund's
investment  adviser  of the  issuing  companies  and  their  prospects.  This is
referred to as a "value"  approach which is further  described on the Growth and
Income  Stock Fund page.  Relative  to the Growth  and Income  Stock  Fund,  the
Capital  Appreciation  Stock Fund will  include  some  smaller,  less  developed
companies  and some  companies  undergoing  more  significant  changes  in their
operations or experiencing  significant changes in their markets.  The fund will
diversify its holdings among various industries and among companies within those
industries,  but will often be less diversified than the Growth and Income Stock
Fund. The combination of these factors  introduces  greater investment risk than
the Growth and Income Stock Fund, but can also provide higher long-term  returns
than are typically available from less risky investments.

   
The fund will typically  invest in securities  representing  every sector of the
S&P 400 in about  (+/-100%)  the same  weightings  as such sector has in the S&P
400. For example, if technology companies represent 10% of the S&P 400, the fund
will  typically  have  between 0% and 20% of its assets  invested in  securities
issued by technology companies.
    

The fund may also invest in  warrants,  preferred  stocks and  convertible  debt
securities, and may invest up to 25% of its assets in foreign securities.

The fund typically sells a stock when the fundamental expectations for buying it
no longer  apply,  the price  exceeds  its value,  or other  stocks  appear more
attractively priced relative to their values.

                               MID-CAP STOCK FUND

INVESTMENT OBJECTIVE
What is this fund's goal?

The Mid-Cap  Stock Fund seeks  long-term  capital  appreciation  by investing in
midsize and small companies.

INVESTOR PROFILE
Who should consider investing in this fund?

You may want to invest more of your assets in this fund if you:

     1.   have a longer investment time horizon;
     2.   are  willing  to  accept  higher  on-going  short-term  risk  for  the
          potential of higher long-term returns;
     3.   want to diversify your investments;
     4.   are  seeking  a fund for the  growth  portion  of an asset  allocation
          program;
     5.   are  seeking  exposure  to  smaller  companies  as  part  of an  asset
          allocation program; or
     6.   are investing for retirement or other goals that are many years in the
          future.

PRINCIPAL RISKS
What are the main risks of investing in this fund?

As with any fund that  invests  in equity  securities,  this fund is  subject to
market  risk,  the risk  that the value of your  investment  will  fluctuate  in
response  to stock  market  movements.  Loss of money is a  significant  risk of
investing in this fund.

Due to its focus on smaller  companies'  stocks that may appreciate in value and
lack of emphasis on those that provide current income,  this fund will typically
experience  greater  volatility over time than the Growth and Income Stock Fund.
Securities issued by smaller companies may be less liquid than securities issued
by larger,  more  established  companies.  In  addition,  a "value"  approach to
investing  includes the risks that: 1. the securities markets will not recognize
the value of a security for an unexpectedly  long period of time; and 2. a stock
that  is  believed  to  be  undervalued  actually  is  appropriately  priced  or
over-priced  due  to  unanticipated  problems  associated  with  the  issuer  or
industry.

To the extent  that the fund  invests  in  higher-risk  securities,  it takes on
additional risks that could adversely affect its  performance.  For example,  to
the extent that the fund  invests in foreign  securities,  it will be subject to
the risks related to such securities, including the risks of changes in the rate
of currency  exchange and varying political  situations.  The principal risks of
foreign  securities  and  small  company  stocks  are  described  later  in this
prospectus and in the SAI.

PRINCIPAL INVESTMENT STRATEGIES
How does this fund pursue its objective?

The Mid-Cap Stock Fund invests primarily in common stocks of midsize and smaller
companies  (market  capitalization  of less  than  $10  billion  at the  time of
purchase), and will under normal market conditions, maintain at least 80% of its
assets in such securities. However, the fund will not automatically sell a stock
just  because  the  company's  market  capitalization  has grown  beyond the $10
billion  upper  limit and such  position  may be  increased  through  additional
purchases.

                         MID-CAP STOCK FUND (Continued)

INVESTOR PROFILE(Continued)
Who should consider investing in this fund?

You may want to invest fewer of your assets in this fund if you:

     1.   are investing with a shorter investment time horizon in mind;
     2.   are seeking an investment based on income rather than capital gain; or
     3.   are   uncomfortable   with  an   investment   whose   value  may  vary
          substantially.

PRINCIPAL  INVESTMENT  STRATEGIES  (Continued)
How does  this fund  pursue  its objective?

The fund seeks  stocks in this  midsize to smaller  range that have a low market
price relative to their value as estimated based on fundamental  analysis of the
issuing  company and its prospects.  This is sometimes  referred to as a "value"
approach.  Relative to both the Growth and Income Stock and Capital Appreciation
Stock Funds,  the Mid-Cap Stock Fund will include more smaller,  less  developed
issuers.  These midsize and smaller  companies often have  difficulty  competing
with larger  companies,  but the successful ones tend to grow faster than larger
companies. They often use profits to expand rather than to pay dividends.

The fund  will  diversify  its  holdings  among  various  industries  and  among
companies  within those  industries but will often be less  diversified than the
Growth and Income  Stock  Fund.  The  combination  of these  factors  introduces
greater  investment  risk than the Growth and Income  Stock  Fund,  but can also
provide higher  long-term  returns than are typically  available from less risky
investments.

The fund will typically  invest in securities  representing  every sector of the
S&P 400 Midcap Index in about  (+/-100%) the same  weightings as such sector has
in the S&P 400 Midcap Index. For example, if technology  companies represent 10%
of the S&P 400 Midcap Index,  the fund will typically have between 0% and 20% of
its assets invested in securities issued by technology companies.

The fund may also invest in  warrants,  preferred  stocks and  convertible  debt
securities, and may invest up to 25% of its assets in foreign securities.
    

The fund typically sells a stock when the fundamental expectations for buying it
no  longer  apply,  the price  exceeds  its value or other  stocks  appear  more
attractively priced relative to their values.

Note:  The  Mid-Cap  Stock  Fund is a new fund  that  does  not have  historical
investment  performance.  When it does, its performance will be shown along with
the performance of the S&P 400 Midcap Index and the Russell Midcap Index,  which
are measures of the  performance  of the relevant  market.  The following  table
shows the historical performance of these indexes.

                                 RISK VS. RETURN

The  risk/return  curve below  demonstrates  that,  in general  for  diversified
portfolios of securities of the various types,  as short-term risk increases the
potential for long-term  gain also  increases.  "Short-term  risk" refers to the
likely  volatility  of a fund's total return and its  potential for gain or loss
over a  relatively  short time  period.  "Long-term  potential  gain"  means the
expected average annual total return over a relatively long time period, such as
20 years.

GRAPHIC:  This graphic  shows where each of the funds in the Ultra Series Fund,
in addition to other types of investments, fall on a curve that depicts the risk
taken for the gain  potential.  The x-axis is labelled  "Long Term Potential for
Gains"; the y-axis is labelled "Short Term Risk (Volatility of Returns)."

This curve is not intended to indicate future  volatility or performance.  It is
merely intended to demonstrate the relationship  between the on-going short-term
risk and the long-term  potential for gain of each portfolio of the Ultra Series
Fund relative to other funds and types of investments.

Although  each  fund  expects  to  pursue  its  investment  objective  using its
principal investment strategies  regardless of market conditions,  each fund may
invest up to 100% of its assets in money market securities as a defensive tactic
in abnormal market conditions.

The  preceding  fund  pages  provide  descriptions  of  the  general  investment
strategies  and what we believe to be the principal  risks of each of the funds.
The fund pages do not  contain an  exhaustive  description  of all the risks and
investment strategies of the funds. Please read each of the fund pages to gain a
basic  understanding  of the funds. For a more detailed  description,  including
non-principal risks, investment strategies, and investment restrictions,  please
consult the  Statement of  Additional  Information.  Also, if there are terms or
concepts you do not fully  understand,  please consult the SAI, other  reference
material or your registered representative before investing.

              RISKS ASSOCIATED WITH CERTAIN HIGHER RISK SECURITIES

                               FOREIGN SECURITIES

As  indicated in the earlier  pages,  several of the funds may invest in foreign
equity and debt securities. Foreign securities are securities that are issued by
companies  organized or whose  principal  operations  are outside the U.S.,  are
issued by a foreign  government,  are principally traded outside of the U.S., or
are quoted or  denominated  in a foreign  currency.  Equity  securities  include
common stocks,  securities convertible into common stocks, preferred stocks, and
other  securities  representing  equity  interests  such as American  depository
receipts ("ADRs"),  European  depository receipts ("EDRs") and global depository
receipts  ("GDRs").  The fund may also invest in debt securities,  foreign money
market  instruments,  and other  income  bearing  securities  as well as forward
foreign  currency  exchange  contracts  and  other  derivative   securities  and
contracts.

Investing in foreign  securities  involves  certain special  considerations  and
additional risks which are not typically associated with investing in securities
of domestic issuers or U.S. dollar denominated securities.  For example, foreign
securities are typically subject to:

     1.   Fluctuations in currency exchange rates.

     2.   Higher  trading and custody  charges  compared to  securities  of U.S.
          companies.

     3.   Different accounting and reporting practices than U.S. companies. As a
          result, it is often more difficult to evaluate  financial  information
          from foreign issuers.  Also, the laws of some foreign  countries limit
          the information that is made available to investors.

     4.   Less stringent securities regulations than those of the U.S.

     5.   Potential political instability.
   
     6.   Potential  economic  instability.  The economies of individual foreign
          countries may differ favorably or unfavorably from the U.S. economy in
          such respects as growth of gross domestic product,  rate of inflation,
          and industry diversification. Such differences may cause the economies
          of these  countries  to be less stable  than the U.S.  economy and may
          make them more sensitive to economic fluctuations.
    
Some of the  investments  will be stocks or bonds of  relatively  large  issuers
located or operating in developed countries. Such securities are those generally
representative   of  the  companies   comprising  the  Morgan  Stanley   Capital
International, Europe, Australia, and Far East ("EAFE") Stock Index.

                                EURO CONVERSION
   
On January 1, 1999,  the  European  Monetary  Union  ("EMU")  implemented  a new
currency unit, the Euro. In effect,  the Euro will become the official  currency
of the EMU and will replace the individual  currencies  previously  used by many
European countries. About 46% of the stock exchange capitalization of the entire
European market moved to Euros, and  participating  governments will issue their
bonds in Euros.  The Euro  transition  may adversely  affect  financial  markets
world-wide  and may result in changes in the  relative  strength  of other major
currencies,  including the U.S. dollar. It is not possible to accurately predict
what  affect,  if any,  the  conversion  to the Euro by the EMU will have on the
operations of the funds or the securities markets in general. However, if a fund
invests in securities denominated by the Euro, the fund will be exposed to risks
relating to the Euro conversion. For more details, please refer to the SAI.
    
<PAGE>
                          SMALL CAPITALIZATION STOCKS

Certain funds may also invest in small capitalization stocks and stocks or bonds
principally  traded in emerging  securities  markets or of issuers located in or
having substantial  business operations in emerging  economies.  The downside of
investing in smaller companies is that such investments entail a higher level of
risk  compared  to larger,  more  established  companies.  Small  capitalization
companies  often  do not  have  the  financial  strength  needed  to do  well in
difficult  economic  times.  Also,  they often sell limited numbers of products,
which can make it harder for them to compete with larger companies. As a result,
their  securities  prices may fluctuate more over the short-term,  but they have
more  potential to grow.  The  emerging  economies in which the fund invests are
located primarily in the Asia-Pacific region,  Eastern Europe, Central and South
America, and Africa. The small size,  inexperience and limited trading volume of
the securities  markets in certain of these countries may also make  investments
in such countries  more volatile and less liquid than  investments in securities
traded in markets in Japan and Western European countries. 

                                   THE SHARES

                                     OFFER

Currently,  each series of shares is divided into two classes. Class C and Class
Z are identical except that Class C shares bear a distribution fee pursuant to a
distribution  plan  (the  "Distribution  Plan"),  described  below,  adopted  in
accordance with Rule 12b-1 under the Act.

Both Classes are sold in a continuous offering.  The Ultra Series Fund generally
offers Class Z shares to separate accounts of CUNA Mutual Group and to qualified
pension and retirement  plans of CUNA Mutual Group. The Ultra Series Fund offers
Class C shares to separate  accounts of  insurance  companies  and to  qualified
pension and retirement plans that are not affiliated with CUNA Mutual Group. The
fund does not offer its shares directly to the general public.

Investments in the Ultra Series Fund by separate accounts of insurance companies
are made through either variable  annuity or variable life insurance  contracts,
together commonly known as variable contracts.  Each separate account contains a
subaccount that corresponds to a portfolio in the Ultra Series Fund.

                            PURCHASE AND REDEMPTION

On each day that a Fund's net asset value is  calculated,  the Ultra Series Fund
processes  any orders to  purchase or redeem  shares.  Purchase  and  redemption
orders are  processed at each fund's net asset value  calculated  on the day the
order is received,  although orders may be executed the next morning. Shares are
purchased  and  redeemed at net asset value  without the  deduction  of sales or
redemption charges.

For a more detailed  description of the procedures for allocating  interest in a
separate  account to a portfolio of the Ultra Series Fund,  owners of individual
variable contracts should refer to the separate  prospectus for their contracts;
and participants in qualified  pension or retirement plans should refer to their
plan documents.

Treasury 2000 Fund Only: The Ultra Series Fund anticipates  demand for shares in
the Treasury  2000 Fund to decrease as the portfolio  maturity date  approaches.
Also, it may not be possible to purchase additional Stripped Treasury Securities
with a maturity date the same as the Stripped  Treasury  Securities in the fund.
Accordingly,  the Ultra Series Fund may stop  selling  shares in the fund if the
Trustees  decide further sale of shares in the fund is not in its best interest.
At some  time  during  the 12  months  before  maturity  of the  portfolio,  the
securities will be liquidated and the proceeds (after deductions for accrued but
unpaid  fees,  taxes,  governmental  and other  charges)  will be  automatically
invested at the Net Asset Value in the Money Market  Fund,  unless an owner of a
variable contract directs otherwise.  No charge will be made for reinvestment of
these proceeds.  At least 45 days before the portfolio  maturity date, the Ultra
Series Fund will mail to each owner of a variable  contract  with an interest in
the fund a Notice of Impending Maturity.  The notice will state that, unless the
Ultra Series Fund  receives a written  request to invest the proceeds in another
fund at least five days prior to portfolio  maturity,  on the date the portfolio
matures,  each  owner's  proceeds  will be  automatically  invested in the Money
Market Fund.
<PAGE>
                                  DISTRIBUTION

The Ultra Series Fund has adopted a Distribution  Plan pursuant to Rule 12b-1 of
the Act under which the Ultra Series Fund bears certain expenses relating to the
distribution of Class C shares.  The  Distribution  Plan provides that the Ultra
Series Fund will pay CUNA Brokerage  Services,  Inc. a distribution fee of 0.25%
of the  average  daily net assets of Class C shares of each fund  annually.  The
distribution  fee is calculated and accrued daily and paid quarterly or at other
times as agreed upon by the Ultra Series Fund and CUNA Brokerage Services,  Inc.
The  distribution  fee is paid  out of each  fund's  assets  supporting  Class C
shares.  This means that the net asset value of Class C shares is reduced by the
daily  accrual of the fee. The net asset value of Class Z shares is not affected
by the  distribution  fee. Over time,  these fees will increase the cost of your
investment  in Class C shares and may cost you more than  paying  other types of
sales charges.

                                   DIVIDENDS

Dividends of the various  funds in the Ultra Series Fund (except  those from the
Treasury 2000 Fund) are distributed to separate accounts for variable  contracts
and qualified pension or retirement plans and automatically  reinvested in Ultra
Series Fund shares.

Dividends from the Money Market Fund are declared  daily and reinvested  monthly
in full and fractional shares of the Money Market Fund.

Dividends of ordinary income from the Bond,  Balanced,  Growth and Income Stock,
Capital  Appreciation  Stock  and  Mid-Cap  Stock  Funds  will be  declared  and
reinvested  quarterly in full and fractional shares.

Dividends of capital  gains from these funds will be declared and  reinvested at
least  annually in full and  fractional  shares.  In no event will  capital gain
dividends be declared and paid more frequently than allowed under SEC rules.

Annually,  the Treasury  2000 Fund will declare a "consent"  dividend for income
tax purposes.

The funds'  distributions  may be subject to federal  income tax. An exchange of
fund  shares may also be  treated  as a sale of fund  shares and any gain on the
transaction may be subject to federal income tax.

                             PRICING OF FUND SHARES

The funds'  shares are sold and redeemed at the shares' net asset value  without
sales or  redemption  charges.  Net asset  value is computed by adding the total
current values of each fund's assets,  subtracting  all liabilities and dividing
by the  number  of  outstanding  shares.  On each day that  net  asset  value is
calculated,  the calculation occurs at the earlier of 3:00 p.m. Central Standard
Time or the close of the New York Stock Exchange.

Net asset values are  calculated on any day the New York Stock  Exchange is open
for business.

Federal  securities  regulations  will be followed in case of an emergency  that
interferes with valuation of shares.

The funds'  shares will be  purchased  and  redeemed  at their net asset  value.
Generally,  the  assets of each fund are  valued  using  market  quotations  and
independent  pricing  services.  If these  are not  available,  the value of the
assets  of the  funds  will be based on their  "fair  value"  as  determined  in
accordance with procedures  adopted by the Board of Trustees.  The assets of the
Money Market Fund and other short-term  investments having maturities of 60 days
or less will be valued at amortized cost. More information about the calculation
of net asset value is in the SAI.

                                     TAXES

For federal income tax purposes, each Fund will be treated as a separate entity.
Each Fund intends to qualify each year as a "regulated investment company" under
the Internal Revenue Code, as amended (the "Code"). By so qualifying,  a Fund is
not subject to federal income tax to the extent that its net  investment  income
and net realized  capital  gains are  distributed  to the  separate  accounts of
insurance  companies or to qualified plans.  Further,  each Fund intends to meet
certain  diversification  requirements  applicable  to mutual  funds  underlying
variable life insurance and variable annuity contracts.

The Shareholders of the Funds are qualified pension and profit sharing plans and
the separate  accounts of life  insurance  companies.  Under  current law,  plan
participants  and owners of variable life insurance and annuity  contracts which
have  invested  in a Fund  are  not  subject  to  federal  income  tax  on  Fund
distributions  or on gains  realized  upon the sale or redemption of Fund shares
until they are withdrawn from the plan or contracts.

For information concerning the federal tax consequences to the purchasers of the
variable  annuity or variable life insurance  contracts,  see the prospectus for
such  contract.  For more  information  about the tax status of the  Funds,  see
"Taxes" in the SAI.

                              PORTFOLIO MANAGEMENT

The investment adviser for the Ultra Series Fund is:

                                   CIMCO Inc.
                            5910 Mineral Point Road
                             Madison, WI 53701-0391
   
CIMCO was established on July 6, 1982. It provides investment  management of the
investment  portfolios  of CUNA Mutual Group,  its  "permanent  affiliate"  CUNA
Mutual Life Insurance Company,  their  subsidiaries and affiliates,  and MEMBERS
Mutual Funds. CIMCO has over $7 billion of assets under management.
    

CIMCO employs a team approach in the management of investments of all the funds.
The Money  Market,  Treasury  2000,  Bond,  Balanced,  Growth and Income  Stock,
Capital  Appreciation Stock and Mid-Cap Stock Funds are each managed by teams of
portfolio managers employed by CIMCO.

CIMCO manages the assets of the Mid-Cap Stock Fund using a "manager of managers"
approach  under which CIMCO may manage some or all of the fund's  assets and may
allocate  some  or all of the  fund's  assets  among  one or  more  "specialist"
subadvisers.  CIMCO monitors the  performance  of each  subadviser to the extent
that it deems appropriate to achieve a fund's investment objective,  reallocates
fund assets among its own portfolio management team and individual  subadvisers,
or  recommends  to the Ultra  Series Fund board that a fund employ or  terminate
particular subadvisers.
   
As of the date of this prospectus, Heartland Advisors, Inc. is the only
subadviser managing some of the assets of the Mid-Cap Stock Fund. Heartland
Advisors, Inc. also serves as investment adviser to each of the funds in the
Heartland family of funds.  Net assets under management of the Heartland
organization were over $3 billion as of December 31, 1998.
    

In addition to providing portfolio management  services,  CIMCO also provides or
arranges for the provision of substantially  all other services  required by the
funds. Such services include all administrative, accounting, and legal services,
as well as the services of custodians,  transfer agents, and dividend disbursing
agents.

As  payment  for its  services  as the  investment  adviser,  CIMCO  receives  a
management  fee based upon the assets of each fund.  The  management fee paid to
CIMCO is computed  and  accrued  daily and paid  monthly,  as  indicated  in the
Expenses section.

                                   YEAR 2000
   
The Ultra Series Fund, like all funds,  could be adversely  affected by computer
systems  that do not  properly  process  date-related  information  on and after
January 1, 2000.  This is often referred to as "Year 2000" or "Y2K".  While Year
2000 problems  could have a negative  effect on funds,  CIMCO and its affiliated
entities are working to avoid such problems.  They are also obtaining assurances
from service  providers that they are taking  similar  steps.  If the systems of
CIMCO or those of their  service  providers  are not  available  or  malfunction
because  of Year 2000  problems,  then the funds  could  experience  substantial
delays in performing  certain  functions (for example,  processing  purchase and
sale  transactions).  As a result of CIMCO's efforts, it is not anticipated that
its  systems  will  have  any  negative   affects  on  your  Ultra  Series  Fund
investments.

                              GENERAL INFORMATION
   
The Ultra Series Fund is an  investment  company  consisting  of seven  separate
investment  portfolios  or funds (each,  a "Fund") each of which has a different
investment objective. Each Fund is a diversified, open-end management investment
company,  commonly  known as a mutual  fund.  The seven Funds are Money  Market,
Treasury 2000, Bond,  Balanced,  Growth and Income Stock,  Capital  Appreciation
Stock,  and Mid-Cap Stock. The Ultra Series Fund was organized under the laws of
the  Commonwealth of Massachusetts on September 16, 1983, and is a Massachusetts
Business Trust. Under Massachusetts's law, shareholders of a business trust may,
under  certain  circumstances,  be held  personally  liable as partners  for the
obligations  of the Ultra  Series Fund.  The  Declaration  of Trust  contains an
express disclaimer of shareholder liability for acts or obligations of the Ultra
Series  Fund  and  requires  that  notice  of such  disclaimer  be given in each
instrument entered into or executed by the Ultra Series Fund. The Declaration of
Trust provides for indemnification out of the Ultra Series Fund property for any
shareholder held personally liable for the obligations of the Ultra Series Fund.
Thus,  the  risk  of a  shareholder  incurring  financial  loss  on  account  of
shareholder liability is limited to circumstances in which the Ultra Series Fund
itself would be unable to meet its obligations.
    
                              INVESTMENT PRACTICES
   
The Ultra Series Fund is a diversified  open-end  management  investment company
consisting of seven investment portfolios or funds, each with its own investment
objective  and  policies.   The  Ultra  Series  Fund  Prospectus  describes  the
investment  objective  and  policies of each of the seven Funds.  The  following
information is provided for those investors  wishing to have more  comprehensive
information than that contained in the Prospectus. Within the past year, no Fund
has employed any of the following  practices:  lending of portfolio  securities,
investing in restricted  securities,  investing in options,  financial  futures,
stock index futures and related  options.  Except for the Mid-Cap Stock Fund (as
described  below),  no Fund has a current intention of employing these practices
in the foreseeable future.
    
If the Ultra Series Fund enters into futures  contracts or call options thereon,
reverse repurchase agreements,  firm commitment agreements or standby commitment
agreements,  the  Ultra  Series  Fund  will  obtain  approval  from the Board of
Trustees to  establish a  segregated  account  with the  custodian  of the Ultra
Series Fund. The segregated  account will hold liquid assets such as cash,  U.S.
government  assets  and  high-grade  debt  obligations.  The  cash  value of the
segregated  account  will be not less  than  the  market  value  of the  futures
contracts  and  call  options  thereon,  reverse  repurchase  agreements,   firm
commitment agreements and standby commitment agreements.

Lending Portfolio Securities

All Funds,  except the Money Market Fund,  may lend portfolio  securities.  Such
loans  will be made  only  in  accordance  with  guidelines  established  by the
Trustees and on the request of broker-dealers or institutional  investors deemed
qualified,  and only when the borrower  agrees to maintain cash or securities as
collateral with the Fund equal at all times to at least 100% of the value of the
securities.  The Fund will  continue  to receive  interest or  dividends  on the
securities  loaned and will,  at the same time,  earn an  agreed-upon  amount of
interest  on the  collateral  which  will  be  invested  in  readily  marketable
short-term  obligations of high quality.  The Fund will retain the right to call
the loaned  securities and intends to call loaned voting securities if important
shareholder meetings are imminent. Such security loans will not be made if, as a
result,  the  aggregate  of such  loans  exceeds  30% of the value of the Fund's
assets. The Fund may terminate such loans at any time. While there may be delays
in recovery of loaned securities or even a loss of rights in collateral supplied
should the borrower fail financially, loans will be made only to firms deemed by
the  Investment  Adviser to be in good standing and will not be made unless,  in
the judgment of the Investment Adviser, the consideration to be earned from such
loans would justify the risk.

Restricted Securities
   
Each Fund, except the Money Market,  Treasury 2000, and Mid-Cap Stock Funds, may
invest up to 10% of its net assets in restricted  securities.  The Mid-Cap Stock
Fund may invest up to 15% of its net assets in restricted securities. Securities
regulations  limit the resale of restricted  securities which have been acquired
through  private  placement  transactions,  directly  from  the  issuer  or from
security  holders,  generally  at higher  yields or on terms more  favorable  to
investors  than  comparable   publicly  traded   securities.   Privately  placed
securities  are often not readily  marketable and ordinarily can be sold only in
privately negotiated transactions to a limited number of purchasers or in public
offerings  made  pursuant  to an  effective  registration  statement  under  the
Securities Act of 1933.  Private or public sales of such  securities by the Fund
may involve significant delays and expense.  Private sales require  negotiations
with one or more purchasers and generally produce less favorable prices than the
sale of comparable unrestricted  securities.  Public sales generally involve the
time and expense of preparing and processing a registration  statement under the
Securities Act of 1933 and may involve the payment of underwriting  commissions;
accordingly,  the  proceeds  may be less  than  the  proceeds  from  the sale of
securities of the same class which are freely marketable.  Restricted securities
in each Fund will be valued at fair value as  determined  in good faith by or at
the direction of the Trustees for purposes of  determining  the Fund's Net Asset
Value. Such securities,  when possible, will be valued on a comparative basis to
securities with similar characteristics for which market prices are available.
    
Foreign Securities
   
All Funds,  except the  Treasury  2000 Fund,  may invest in foreign  securities.
Investment in foreign issuers involves  investment risks that are different,  in
some  respects,  from an investment  in U.S.  domestic  issuers.  Such risks may
include  foreign  political  and  economic   developments.   Publicly  available
information  concerning  issuers  located  outside the United  States may not be
comparable  in scope  or  depth of  analysis  to that  generally  available  for
publicly  held U.S.  issuers.  Accounting  and auditing  practices and financial
reporting  requirements  may vary  significantly  from  country to  country  and
generally  are  not  comparable  to  those  applicable  to  publicly  held  U.S.
corporations.  In the event of default,  debt obligations of foreign issuers may
be  difficult  to enforce.  The  Investment  Adviser  will make every  effort to
analyze potential investments in foreign issuers on the same basis as the rating
services analyze domestic issuers,  but because public information is not always
comparable  to that  available  on domestic  issuers,  this may not be possible.
Therefore,  while  the  Investment  Adviser  will  make  every  effort to select
investments in foreign securities on the same basis relative to quality and risk
as its  investments  in domestic  securities,  this may not always be  possible.
Except for the  Mid-Cap  Stock  Fund,  no Fund will  invest more than 10% of its
total assets in foreign  securities.  ADRs are not considered foreign securities
for this purpose. However, the Growth and Income Stock, and Capital Appreciation
Stock Funds may invest up to 25% of assets,  and the Balanced Fund may invest up
to 15% of assets in American  Depository  Receipts and foreign  securities.  The
Mid-Cap  Stock  Fund  may  invest  up to 25%  of its  total  assets  in  foreign
securities and has no limitations on ADRs.
    
Put and Call Options

All Funds,  except the Money Market Fund,  may engage in the purchase,  sale and
covered  writing of put and call options that are traded on U.S.  exchanges  and
boards of trade.  A call  option is a contract  (generally  having a duration of
nine  months or less)  pursuant  to which the  purchaser  of the call  option in
return  for a premium  paid,  has the right to buy the  security  or  instrument
underlying the option at a specified  exercise price at any time during the term
of the option. The writer of the call option, who receives the premium,  has the
obligation,  upon exercise of the option, to deliver the underlying  security or
instrument against payment of the exercise price during the option period. A put
option is a similar  contract  which gives the  purchaser of the put option,  in
return for a premium, the right to sell the underlying security or instrument at
a  specified  price  during the term of the option.  The writer of the put,  who
receives the  premium,  has the  obligation  to buy the  underlying  security or
instrument, upon exercise, at the exercise price during the option period.

The  writing  of a call  option is  "covered"  if the Fund  owns the  underlying
security  or  instrument  covered by the call or has an absolute  and  immediate
right  to  acquire  that  security  or  instrument   without   additional   cash
consideration (or for additional cash consideration held in a segregated account
by its custodian) upon conversion or exchange of other securities or instruments
held in its portfolio.  The writing of a call option is also covered if the Fund
holds a call on an  equivalent  amount of the same security or instrument as the
call written where the exercise  price of the call held is equal to or less than
the exercise price of the call written or greater than the exercise price of the
call written if the difference is maintained by the Fund in cash, U.S.  Treasury
bills or other high grade  short-term  obligations in a segregated  account with
its  custodian.  The writing of a put option is "covered" if the Fund  maintains
cash,  U.S.  Treasury bills or other high grade  short-term  obligations  with a
value equal to the exercise price in a segregated account with its custodian, or
else holds a put on an  equivalent  amount of the same security or instrument as
the put written where the exercise  price of the put held is equal to or greater
than the exercise price of the put written. The premium paid by the purchaser of
an option will reflect,  among other things,  the  relationship  of the exercise
price  to the  market  price  and  volatility  of  the  underlying  security  or
instrument,  the remaining term of the option,  supply and demand,  and interest
rates.
   
If the writer of an option wishes to terminate his  obligation,  he may effect a
"closing purchase  transaction." This is accomplished by buying an option of the
same kind as the option previously  written.  The effect of the purchase is that
the clearing  corporation will cancel the writer's  position.  However, a writer
may not effect a closing purchase  transaction after it has been notified of the
exercise of an option.  Likewise, an investor who is the holder of an option may
liquidate  his  position by  effecting  a "closing  sale  transaction."  This is
accomplished  by  selling  an option of the same kind as the  option  previously
purchased.  There is no  guarantee  that either a closing  purchase or a closing
sale transaction can be effected.
    
Effecting a closing transaction in the case of a written call option will permit
the Fund to write another call option on the  underlying  security or instrument
with either a different  exercise  price or  expiration  date or both, or in the
case of a written put option will permit the Fund to write another put option to
the extent  that the  exercise  price  thereof is secured by  deposited  cash or
short-term  securities.  Also,  effecting a closing  transaction will permit the
cash or proceeds  from the  concurrent  sale of any  securities  or  instruments
subject to the option to be used for other Fund investments. If the Fund desires
to sell a particular  security or instrument  from its portfolio on which it has
written  a call  option,  it will  effect  a  closing  transaction  prior  to or
concurrent with the sale of the security or instrument.

The Fund  may  write  put and call  options  only if they are  covered,  and the
options must remain covered so long as a Fund is obligated as a writer.

An option position may be closed out only on an exchange or board of trade which
provides a secondary  market for an option of the same kind.  Although  the Fund
will  generally  purchase or write only those options for which there appears to
be an active  secondary  market,  there is no assurance that a liquid  secondary
market on an exchange or board of trade will exist for any particular option, or
at any particular  time, and for some options no secondary market on an exchange
or board of trade may exist.  In such event it might not be  possible  to effect
closing transactions in particular options,  with the result that the Fund would
have to  exercise  its  options in order to realize  any profit and would  incur
brokerage  commissions upon the exercise of call options and upon the subsequent
disposition  of  underlying  securities  or  instruments  acquired  through  the
exercise  of call  options or upon the  purchase  of  underlying  securities  or
instruments  for the  exercise of put  options.  If the Fund,  as a covered call
option writer, is unable to effect a closing purchase transaction in a secondary
market, it will not be able to sell the underlying  security or instrument until
the option  expires or it delivers the  underlying  security or instrument  upon
exercise.

The use of put and call  options is  restricted  to no more than twenty  percent
(20%) of the net assets in the Fund using such option.

Financial Futures and Related Options

The  Balanced,  Bond,  and  Treasury  2000 Funds may engage in  transactions  in
financial  futures  contracts or related  options,  but only as a hedge  against
changes in the values of securities held in the Fund's portfolio  resulting from
market conditions or which it intends to purchase and where the transactions are
economically  appropriate  to the  reduction  of risks  inherent  in the ongoing
management  of the Fund.  A Fund may not purchase or sell  financial  futures or
purchase related options if, immediately thereafter,  more than one-third of its
net  assets  would be  hedged.  In  addition,  a Fund may not  purchase  or sell
financial futures or purchase related options if,  immediately  thereafter,  the
sum of the amount of margin  deposits on the Fund's existing  futures  positions
and  premiums  paid for related  options  would  exceed five percent (5%) of the
market value of the Fund's total assets.

Unlike when a Fund  purchases or sells a security,  no price is paid or received
by the Fund upon the purchase or sale of a futures contract. Initially, the Fund
will be required  to deposit  with the  custodian  under the name of the futures
commission  merchant an amount of cash or U.S. Treasury bills,  known as initial
margin.  The nature of initial margin in futures  transactions is different from
that of margin in securities transactions in that a futures contract margin does
not involve  the  borrowing  of funds by a customer to finance the  transaction.
Rather,  the  initial  margin is in the nature of a  performance  bond or a good
faith deposit on a contract  which is returned to the Fund upon  termination  of
the Fund's contract  assuming all contractual  obligations  have been satisfied.
Subsequent payments, called "variation margin," to or from the custodian will be
made on a daily basis as the price of the  underlying  securities or instruments
fluctuates  making the long and short positions in the futures  contract more or
less  valuable,  a process  known as "mark to the  market." At any time prior to
expiration of the futures contract,  the Fund may elect to close the position by
taking an opposite  position which will operate to terminate the Fund's position
in the futures contract. A final determination of variation margin is then made,
additional  cash is required to be paid by or released to the Fund, and the Fund
realizes a loss or a gain.

There are several  risks in  connection  with the use of financial  futures as a
hedging  device.  One risk arises because of the imperfect  correlation  between
movements in the price of the futures  contracts  and  movements in the price of
the securities or instruments  which are the subject of the hedge.  The price of
the futures contract may move more than or less than the price of the securities
or  instruments  being hedged.  If the price of the futures  contract moves less
than the price of the  securities  or  instruments  which are the subject of the
hedge, the hedge will not be fully effective but, if the price of the securities
or  instruments  being hedged has moved in an  unfavorable  direction,  the Fund
would be in a better  position than if it had not hedged at all. If the price of
the securities being hedged has moved in a favorable  direction,  this advantage
will be partially  offset by the futures.  If the price of the futures  contract
moves more than the price of the  securities or  instruments  being hedged,  the
Fund will experience  either a loss or a gain on the futures contract which will
not be  completely  offset  by  movements  in the  price  of the  securities  or
instruments.  To compensate  for the imperfect  correlation  of movements in the
price of  securities or  instruments  being hedged and movements in the price of
the futures contracts, the Fund may buy or sell financial futures contracts in a
greater  dollar amount than the dollar amount of securities  being hedged if the
historical volatility of the prices of such securities has been greater than the
historical volatility of the futures. Conversely, the Fund may buy or sell fewer
financial  futures  contracts if the  historical  volatility of the price of the
securities being hedged is less than the historical volatility of the futures.

The financial impact of any use of financial  futures is subject to movements in
interest rates. For example,  if the Fund is hedged against the possibility of a
rise in  interest  rates,  adversely  affecting  the value of bonds  held in its
portfolio,  and bond prices increase instead,  the Fund will lose part or all of
the benefit of the increased  value of its bonds which it has hedged  because it
will have  offsetting  losses in its futures  positions.  In  addition,  in such
situations, if the Fund has insufficient cash, it may have to sell securities to
meet daily variation margin  requirements.  Such sales of securities may be, but
will not  necessarily  be, at increased  prices which reflect the rising market.
The Fund may have to sell securities at a time when it may be disadvantageous to
do so.

Stock Index Futures and Related Options
   
The Balanced,  Growth and Income Stock,  Capital Appreciation Stock, and Mid-Cap
Stock Funds may engage in  transactions  in stock  index  futures  contracts  or
related  options,  but only as a hedge  against  changes  resulting  from market
conditions in the values of securities held in the Fund's portfolio or which the
Fund intends to purchase and where the transactions are economically appropriate
to the reduction of risks inherent in the ongoing management of the Fund. A Fund
may not  purchase or sell stock index  futures or purchase  related  options if,
immediately  thereafter,  more than one-third of its net assets would be hedged.
In  addition,  a Fund may not  purchase or sell stock index  futures or purchase
related  options  if,  immediately  thereafter,  the sum of the amount of margin
deposits on the Fund's existing futures  positions and premiums paid for related
options would exceed twenty percent (20%) of net assets.

There are several risks in  connection  with the use of stock index futures as a
hedging  device.  One risk arises because of the imperfect  correlation  between
movements in the price of the stock index futures  contract and movements in the
price of the  securities  which are the  subject of the hedge.  The price of the
stock index futures may move more than or less than the price of the  securities
being hedged.  If the price of the stock index futures  contract moves less than
the price of the securities  which are the subject of the hedge,  the hedge will
not be fully  effective  but, if the price of the  securities  being  hedged has
moved in an unfavorable  direction,  the Fund would be in a better position than
if it had not hedged at all.  If the price of the  securities  being  hedged has
moved in a favorable  direction,  this advantage will be partially offset by the
futures contract. If the price of the futures contract moves more than the price
of the stock,  the Fund will  experience  either a loss or a gain on the futures
contract  which will not be  completely  offset by movements in the price of the
securities  which are the subject of the hedge.  To compensate for the imperfect
correlation  of movements in the price of securities  being hedged and movements
in the price of the stock  index  futures,  the Fund may buy or sell stock index
futures  contracts  in a  greater  dollar  amount  than  the  dollar  amount  of
securities  being  hedged if the  historical  volatility  of the  prices of such
securities  has  been  greater  than the  historical  volatility  of the  index.
Conversely,  the Fund may buy or sell fewer stock index futures contracts if the
historical  volatility of the price of the securities  being hedged is less than
the historical volatility of the stock index.

The  financial  impact of any use of stock index futures is subject to movements
in the direction of the market. For example,  if the Fund has hedged against the
possibility of a decline in the market  adversely  affecting  stocks held in its
portfolio and stock prices increase  instead,  the Fund will lose part or all of
the benefit of the increased  value of its stocks which it has hedged because it
will have  offsetting  losses in its futures  positions.  In  addition,  in such
situations, if the Fund has insufficient cash, it may have to sell securities to
meet daily variation margin  requirements.  Such sales of securities may be, but
will not  necessarily  be, at increased  prices which reflect the rising market.
The Fund may have to sell securities at a time when it may be disadvantageous to
do so.

Compared to the use of stock  index  futures,  the  purchase of options on stock
index futures involves less potential risk because the maximum amount at risk is
the premium paid for the options (plus transaction costs). However, there may be
circumstances  when the use of an option on a stock index future would result in
a loss when the use of a stock index future would not,  such as when there is no
movement in the level of the index.

Bond Fund Practices

The Bond Fund  will  emphasize  investment  grade,  primarily  intermediate-term
securities. If an investment grade security is downgraded by the rating agencies
or  otherwise  falls  below  the  investment  quality  standards  stated  in the
Prospectus,  management will retain that instrument only if management  believes
it is in the best  interest  of the Fund.  The Fund may invest  more than twenty
percent (20%) of total assets in corporate debt securities  which are not in the
four highest  ratings by Standard and Poor's  Corporation  or Moody's  Investors
Service,  Inc. The Fund may also invest in debt  options,  interest rate futures
contracts, and options on interest rate futures contracts.

The Fund may  utilize  interest  rate  futures and options to manage the risk of
fluctuating  interest rates.  These  instruments will be used to control risk or
obtain additional income and not with a view toward  speculation.  The Fund will
invest only in futures and options which are traded on U.S.  exchanges or boards
of trade.

In the fixed income securities market, purchases of some issues are occasionally
made under firm (forward) commitment  agreements.  Purchases of securities under
such  agreements  can involve  risk of loss due to changes in the market rate of
interest  between the commitment  date and the  settlement  date. As a matter of
operating  policy,  the Fund  will  not  commit  itself  to  forward  commitment
agreements  in an amount in excess of 25% of net  assets  and will not engage in
such  agreements  for  leveraging  purposes.  For  purposes of this  limitation,
forward  commitment  agreements are defined as those  agreements  involving more
than five business days between the commitment date and the settlement date.

Lower-Rated Corporate Debt Securities

As described in the prospectus, each fund, other than the Money Market Fund, may
make certain  investments  including corporate debt obligations that are unrated
or  rated  in the  lower  rating  categories  (i.e.,  ratings  of BB or lower by
Standard & Poor's or Ba or lower by  Moody's).  Bonds rated BB or Ba or below by
Standard & Poor's or Moody's (or  comparable  unrated  securities)  are commonly
referred to as  "lower-rated"  securities or as "junk bonds" and are  considered
speculative and may be questionable  as to principal and interest  payments.  In
some  cases,  such  bonds may be highly  speculative,  have poor  prospects  for
reaching investment standing and be in default. As a result,  investment in such
bonds  will  entail  greater   speculative  risks  than  those  associated  with
investment  in  investment-grade  bonds (i.e.,  bonds rated AAA, AA, A or BBB by
Standard & Poor's or Aaa, Aa, A or Baa by Moody's).

An economic  downturn  could  severely  affect the  ability of highly  leveraged
issuers of junk  bonds to  service  their  debt  obligations  or to repay  their
obligations upon maturity.  Factors having an adverse impact on the market value
of lower  rated  securities  will have an  adverse  effect on a fund's net asset
value to the extent it invests in such securities. In addition, a fund may incur
additional expenses to the extent it is required to seek recovery upon a default
in payment of principal or interest on its portfolio holdings.

The  secondary  market  for  junk  bond  securities,  which is  concentrated  in
relatively few market makers,  may not be as liquid as the secondary  market for
more highly rated  securities,  a factor  which may have an adverse  effect on a
fund's  ability to dispose of a particular  security when  necessary to meet its
liquidity  needs.  Under adverse  market or economic  conditions,  the secondary
market for junk bond  securities  could  contract  further,  independent  of any
specific adverse changes in the condition of a particular  issuer.  As a result,
the Investment  Adviser could find it more difficult to sell these securities or
may be able to sell the securities  only at prices lower than if such securities
were widely traded. Prices realized upon the sale of such lower rated or unrated
securities,  under  these  circumstances,  may be less than the  prices  used in
calculating a fund's net asset value.
   
Since investors  generally perceive that there are greater risks associated with
lower-rated debt  securities,  the yields and prices of such securities may tend
to  fluctuate  more than  those for  higher  rated  securities  do. In the lower
quality segments of the fixed-income  securities market,  changes in perceptions
of  issuers'  creditworthiness  tend  to  occur  more  frequently  and in a more
pronounced manner than do changes in higher quality segments of the fixed-income
securities market resulting in greater yield and price volatility.
    
Another  factor  which  causes   fluctuations  in  the  prices  of  fixed-income
securities is the supply and demand for similarly rated securities. In addition,
the prices of fixed-income securities fluctuate in response to the general level
of interest rates. Fluctuations in the prices of portfolio securities subsequent
to their  acquisition  will not affect cash income from such securities but will
be reflected in a fund's net asset value.

Lower-rated  (and comparable  non-rated)  securities tend to offer higher yields
than  higher-rated  securities with the same  maturities  because the historical
financial  condition  of the  issuers  of such  securities  may not have been as
strong as that of other  issuers,  increasing  the  risks of loss of income  and
principal versus  higher-rated  securities.  In addition to the risk of default,
there are the related  costs of recovery on  defaulted  issues.  The  Investment
Adviser  will  attempt to reduce these risks  through  diversification  of these
funds'  portfolios and by analysis of each issuer and its ability to make timely
payments of income and principal,  as well as broad economic trends in corporate
developments.

Foreign Government Securities

All of the  funds  other  than  the  Treasury  2000  Fund  may  invest  in  debt
obligations of foreign governments and governmental agencies, including those of
emerging  countries.  Investment in sovereign debt obligations  involves special
risks not present in debt  obligations of corporate  issuers.  The issuer of the
debt or the governmental  authorities that control the repayment of the debt may
be unable or unwilling to repay  principal  or interest  when due in  accordance
with the terms of such  debt,  and the funds may have  limited  recourse  in the
event of a default. Periods of economic uncertainty may result in the volatility
of market prices of sovereign debt and in turn the fund's net asset value,  to a
greater extent than the volatility inherent in debt obligations of U.S. issuers.
A sovereign debtor's  willingness or ability to repay principal and pay interest
in a timely  manner may be  affected  by,  among  other  factors,  its cash flow
situation,  the extent of its foreign  currency  reserves,  the  availability of
sufficient  foreign  exchange on the date a payment is due, the relative size of
the debt service burden to the economy as a whole, the sovereign debtor's policy
toward principal  international lenders and the political constraints to which a
sovereign debtor may be subject.

Convertible Securities
   
The Balanced,  Growth and Income Stock,  Capital Appreciation Stock, and Mid-Cap
Stock Funds may each invest in convertible  securities.  Convertible  securities
may include  corporate  notes or preferred  stock but are ordinarily a long-term
debt  obligation  of the issuer  convertible  at a stated  conversion  rate into
common stock of the issuer. As with all debt and income-bearing  securities, the
market  value of  convertible  securities  tends to  decline as  interest  rates
increase and,  conversely,  to increase as interest rates  decline.  Convertible
securities   generally   offer   lower   interest   or   dividend   yields  than
non-convertible securities of similar quality. However, when the market price of
the common stock underlying a convertible security exceeds the conversion price,
the  price  of the  convertible  security  tends  to  reflect  the  value of the
underlying  common  stock.  As the market price of the  underlying  common stock
declines, the convertible security tends to trade increasingly on a yield basis,
and thus may not  decline in price to the same extent as the  underlying  common
stock.  Convertible  securities  rank  senior  to common  stocks in an  issuer's
capital  structure and are  consequently  of higher quality and entail less risk
than the issuer's common stock. In evaluating a convertible security, the fund's
Investment   Adviser  gives  primary  emphasis  to  the  attractiveness  of  the
underlying  common stock. The convertible debt securities in which the funds may
invest are subject to the same rating  criteria  as that fund's  investments  in
non-convertible debt securities.  Convertible debt securities, the market yields
of which are  substantially  below  prevailing  yields on  non-convertible  debt
securities of comparable quality and maturity,  are treated as equity securities
for the purposes of a fund's investment policies or restrictions.
    
Repurchase Agreements

Each fund may enter into repurchase  agreements.  In a repurchase  agreement,  a
security is  purchased  for a relatively  short period  (usually not more than 7
days)  subject to the  obligation  to sell it back to the issuer at a fixed time
and price plus accrued interest. The funds will enter into repurchase agreements
only with member banks of the Federal Reserve System, U.S. Central Credit Union,
and with "primary dealers" in U.S. Government securities. The Investment Adviser
will  continuously  monitor the  creditworthiness  of the parties  with whom the
funds enter into repurchase agreements.

The Trust has established a procedure  providing that the securities  serving as
collateral  for each  repurchase  agreement  must be  delivered  to the  Trust's
custodian  either  physically or in book-entry form and that the collateral must
be marked to market  daily to ensure  that each  repurchase  agreement  is fully
collateralized  at all times.  In the event of  bankruptcy or other default by a
seller of a repurchase agreement,  a fund could experience delays in liquidating
the underlying  securities  during the period in which the fund seeks to enforce
its rights thereto,  possible  subnormal levels of income,  declines in value of
the underlying securities or lack of access to income during this period and the
expense of enforcing its rights.

Reverse Repurchase Agreements

Each fund may also enter into reverse  repurchase  agreements  which involve the
sale of U.S.  Government  securities  held in its  portfolio  to a bank  with an
agreement that the fund will buy back the securities at a fixed future date at a
fixed price plus an agreed  amount of  "interest"  which may be reflected in the
repurchase price. Reverse repurchase  agreements are considered to be borrowings
by the fund entering into them. Reverse  repurchase  agreements involve the risk
that the market value of  securities  purchased by the fund with proceeds of the
transaction may decline below the repurchase price of the securities sold by the
fund which it is obligated to repurchase. A fund that has entered into a reverse
repurchase  agreement  will also continue to be subject to the risk of a decline
in the market value of the securities sold under the agreements  because it will
reacquire those securities upon effecting their repurchase.  To minimize various
risks associated with reverse  repurchase  agreements,  each fund will establish
and maintain with the Trust's custodian a separate account  consisting of liquid
securities,  of any  type or  maturity,  in an  amount  at  least  equal  to the
repurchase  prices of the securities (plus any accrued  interest  thereon) under
such agreements. No fund will enter into reverse repurchase agreements and other
borrowings (except from banks as a temporary measure for extraordinary emergency
purposes) in amounts in excess of 30% of the fund's total assets  (including the
amount  borrowed) taken at market value. No fund will use leverage to attempt to
increase income. No fund will purchase  securities while outstanding  borrowings
exceed  5% of the  fund's  total  assets.  Each  fund will  enter  into  reverse
repurchase  agreements only with federally  insured banks or credit unions which
are approved in advance as being creditworthy by the Trustees.  Under procedures
established  by  the  Trustees,   the   Investment   Adviser  will  monitor  the
creditworthiness of the institutions involved.

U.S. Government Securities

All of the  funds may  purchase  U.S.  Government  Securities.  U.S.  Government
Securities  are  obligations  issued or guaranteed by the U.S.  Government,  its
agencies, authorities or instrumentalities.

Certain U.S.  Government  securities,  including U.S. Treasury bills,  notes and
bonds,  and  Government  National  Mortgage  Association  certificates  ("Ginnie
Maes"),  are  supported by the full faith and credit of the U.S.  Certain  other
U.S.  Government  securities,  issued  or  guaranteed  by  Federal  agencies  or
government sponsored enterprises, are not supported by the full faith and credit
of the U.S.  Government,  but may be  supported  by the  right of the  issuer to
borrow from the U.S.  Treasury.  These  securities  include  obligations  of the
Federal  Home  Loan  Mortgage  Corporation  ("Freddie  Macs"),  and  obligations
supported  by the  credit  of the  instrumentality,  such  as  Federal  National
Mortgage  Association  Bonds ("Fannie Maes"). No assurance can be given that the
U.S.  Government  will  provide  financial  support  to such  Federal  agencies,
authorities,  instrumentalities  and  government  sponsored  enterprises  in the
future. U.S. Government Securities may also include zero coupon bonds.

Ginnie Maes, Freddie Macs and Fannie Maes are  mortgage-backed  securities which
provide monthly payments which are, in effect,  a "pass-through"  of the monthly
interest and principal  payments  (including any prepayments) made by individual
borrowers on the pooled  mortgage  loans.  Collateralized  mortgage  obligations
("CMOs") in which the fund may invest are securities  issued by a corporation or
a U.S.  Government  instrumentality  that are  collateralized  by a portfolio of
mortgages or mortgage-backed securities.  Mortgage-backed securities may be less
effective than  traditional  debt obligations of similar maturity at maintaining
yields during periods of declining  interest rates.  (See  "Mortgage-Backed  and
Asset-Backed Securities.")

Each fund may invest in separately  traded principal and interest  components of
securities  guaranteed  or issued by the U.S.  Treasury if such  components  are
traded  independently  under the  Separate  Trading of  Registered  Interest and
Principal of Securities program ("STRIPS").

All of the funds may acquire securities issued or guaranteed as to principal and
interest by the U.S. Government, its agencies,  authorities or instrumentalities
in the form of custody  receipts.  Such  receipts  evidence  ownership of future
interest  payments,  principal payments or both on certain notes or bonds issued
by the U.S.  Government,  its agencies,  authorities or  instrumentalities.  For
certain securities law purposes, custody receipts are not considered obligations
of the U.S. Government.

Mortgage-Backed and Asset-Backed Securities

The  Money  Market,  Bond,  and  Balanced  Funds may  invest in  mortgage-backed
securities,  which  represent  direct  or  indirect  participation  in,  or  are
collateralized  by and payable from,  fixed rate or variable rate mortgage loans
secured by real property.  These funds may also invest in fixed or variable rate
asset-backed securities, which represent participation in, or are secured by and
payable from, assets such as motor vehicle  installment sales,  installment loan
contracts,  leases of various types of real and personal  property,  receivables
from revolving  credit (i.e.,  credit card)  agreements and other  categories of
receivables.  Such assets are  securitized  though the use of trusts and special
purpose corporations. Payments or distributions of principal and interest may be
guaranteed  up to certain  amounts and for a certain  time period by a letter of
credit or a pool  insurance  policy issued by a credit union or other  financial
institution  unaffiliated  with the Trust, or other credit  enhancements  may be
present.

Mortgage-backed  and  asset-backed  securities  are often  subject to more rapid
repayment  than their  stated  maturity  date would  indicate as a result of the
pass-through  of  prepayments  of principal on the  underlying  loans.  A fund's
ability to maintain  positions in such securities will be affected by reductions
in the principal amount of such securities  resulting from prepayments,  and its
ability to reinvest the returns of principal at comparable  yields is subject to
generally  prevailing  interest  rates at that time.  To the extent  that a fund
invests  in  mortgage-backed  and  asset-backed  securities,  the  values of its
portfolio  securities  will vary with changes in market interest rates generally
and  the  differentials  in  yields  among  various  kinds  of  U.S.  Government
securities and other mortgage-backed and asset-backed securities.

Asset-backed  securities present certain additional risks that are not presented
by mortgage backed securities because  asset-backed  securities generally do not
have the benefit of a security  interest in  collateral  that is  comparable  to
mortgage assets. Credit card receivables are generally unsecured and the debtors
on such  receivables  are  entitled to the  protection  of a number of state and
federal  consumer  credit  laws,  many of which give such  debtors  the right to
set-off certain amounts owed on the credit cards,  thereby  reducing the balance
due.  Automobile  receivables  generally are secured,  but by automobiles rather
than residential real property.  Most issuers of automobile  receivables  permit
the loan servicers to retain  possession of the underlying  obligations.  If the
servicer were to sell these  obligations to another party,  there is a risk that
the  purchaser  would secure an interest  superior to that of the holders of the
asset-backed  securities.  In addition,  because of the large number of vehicles
involved in a typical issuance and technical  requirements under state laws, the
trustee  for the  holders of the  automobile  receivables  may not have a proper
security  interest  in  the  underlying  automobiles.  Therefore,  there  is the
possibility that, in some cases, recoveries on repossessed collateral may not be
available to support payments on these securities.

Forward Commitment and When-Issued Securities

Each fund may purchase  securities on a when-issued or forward commitment basis.
"When-issued"  refers to  securities  whose terms are  specified and for which a
market  exists,  but  which  have not been  issued.  Each  fund  will  engage in
when-issued  transactions with respect to securities purchased for its portfolio
in order to obtain what is considered to be an  advantageous  price and yield at
the time of the transaction.  For when-issued  transactions,  no payment is made
until  delivery is due,  often a month or more after the purchase.  In a forward
commitment  transaction,  a fund  contracts to purchase  securities  for a fixed
price at a future date beyond customary settlement time.

When a fund  engages in forward  commitment  and  when-issued  transactions,  it
relies on the seller to consummate the transaction. The failure of the issuer or
seller to  consummate  the  transaction  may  result in the  fund's  losing  the
opportunity  to obtain a price  and yield  considered  to be  advantageous.  The
purchase  of  securities  on a  when-issued  or  forward  commitment  basis also
involves a risk of loss if the value of the  security to be  purchased  declines
prior to the settlement date.

On the  date a fund  enters  into  an  agreement  to  purchase  securities  on a
when-issued or forward  commitment  basis, the fund will segregate in a separate
account cash or liquid  securities,  of any type or maturity,  equal in value to
the  fund's  commitment.  These  assets  will be  valued  daily at  market,  and
additional  cash or securities  will be segregated in a separate  account to the
extent  that the total  value of the assets in the  account  declines  below the
amount of the  when-issued  commitments.  Alternatively,  a fund may enter  into
offsetting contracts for the forward sale of other securities that it owns.

                             INVESTMENT LIMITATIONS
   
The Ultra  Series Fund has  adopted  the  following  restrictions  and  policies
relating  to the  investment  of assets and the  activities  of each  Fund.  The
policies in this  INVESTMENT  LIMITATION  section are fundamental and may not be
changed  for a Fund  without  the  approval  of the holders of a majority of the
outstanding  votes of that Fund (which for this purpose and under the Investment
Company  Act of 1940 (the  "Act")  means the lesser of (i)  sixty-seven  percent
(67%) of the outstanding votes  attributable to shares  represented at a meeting
at which more than fifty percent (50%) of the outstanding votes  attributable to
shares are  represented or (ii) more than fifty percent (50%) of the outstanding
votes  attributable to shares).  Except as noted below, none of the Funds within
the Ultra Series Fund may:

     1.   Borrow  money in excess of  one-third of the value of its total assets
          taken at market value  (including  the amount  borrowed) and then only
          from banks as a  temporary  measure  for  extraordinary  or  emergency
          purposes. This borrowing provision is not for investment leverage, but
          solely to facilitate management of a Fund by enabling the Fund to meet
          redemption  requests where the  liquidation of an investment is deemed
          to be  inconvenient or  disadvantageous.  Except for the Mid-Cap Stock
          Fund,  a Fund  will  not  make  additional  investments  while  it has
          borrowings outstanding.
    
     2.   Underwrite securities of other issuers, except that a Fund may acquire
          portfolio  securities under circumstances where, if the securities are
          later publicly  offered or sold by the Fund, it may be deemed to be an
          underwriter for purposes of the Securities Act of 1933.

     3.   Invest over  twenty-five  percent  (25%) of assets taken at its market
          value in any one industry. Securities issued or guaranteed by the U.S.
          Government, its agencies or instrumentalities,  or instruments secured
          by these money  market  instruments,  such as  repurchase  agreements,
          shall not be considered  investments  in any one industry for purposes
          of these rules. Telephone,  gas, and electric utility industries shall
          be considered separate industries.
   
     4.   Purchase or sell  commodities,  commodity  contracts (except financial
          futures  contracts),   foreign  exchange  or  real  estate,  including
          interests in real estate  investment  trusts whose  securities are not
          readily marketable or invest in oil, gas or other mineral  development
          or  exploration  programs.  (This does not prohibit  investment in the
          securities of corporations which own interests in commodities, foreign
          exchange,  real estate or oil,  gas or other  mineral  development  or
          exploration programs.) The Mid-Cap Stock Fund may invest in securities
          related to oil,  gas,  or other  mineral  development  or  exploration
          programs.
    
     5.   Invest  more than five  percent  (5%) of the value of the  assets of a
          Fund  in  securities  of any one  issuer,  except  in the  case of the
          securities issued or guaranteed by the U.S.  Government,  its agencies
          or instrumentalities.
   
     6.   Invest  in  securities  of a company  for the  purpose  of  exercising
          control  or  management.  The  Mid-Cap  Stock  Fund may engage in such
          activities.
    
     7.   Invest  in  securities  issued  by  any  other  registered  investment
          companies  in  excess of five  percent  (5%) of total  assets,  nor in
          excess of three percent (3%) of the assets of the acquired  investment
          company.  Not more than ten  percent  (10%) of total  assets  taken at
          market value will be invested in such securities.

     8.   Purchase or sell real estate,  except a Fund may  purchase  securities
          which are issued by companies which invest in real estate or interests
          therein.
   
     9.   Issue senior  securities  as defined in the Act,  except  insofar as a
          Fund may be deemed to have  issued a senior  security by reason of (a)
          entering  into  any  repurchase  agreement;  (b)  borrowing  money  in
          accordance with  restrictions  described above; (c) lending  portfolio
          securities;  (d)  purchasing  securities on a  when-issued  or delayed
          delivery  basis;  or (e)  accommodating  short  sales.  If  the  asset
          coverage falls below three hundred  percent  (300%),  when taking into
          account  items (a) through  (e), a Fund may be  required to  liquidate
          investments to be in compliance with the Act.
    
     10.  Lend  portfolio  securities  in excess of thirty  percent (30%) of the
          value of its total assets.  Any loans of portfolio  securities will be
          made according to guidelines  established  by the Trustees,  including
          maintenance  of collateral of the borrower at least equal at all times
          to the current market value of the securities loaned.
   
     11.  Invest in illiquid assets (which include repurchase agreements that do
          not  mature  within  seven  (7)  days,  non-negotiable  time  deposits
          maturing  in over  seven (7) days,  restricted  securities,  and other
          securities  for which there is no ready market) in an amount in excess
          of ten  percent  (10%) of the value of its total  assets.  The Mid-Cap
          Stock Fund may invest up to fifteen  percent (15%) of the value of its
          net assets in illiquid assets.
    
     12.  Make  loans (the  acquisition  of bonds,  debentures,  notes and other
          securities as permitted by the  investment  objectives of a Fund shall
          not be  deemed  to be the  making  of  loans)  except  that a Fund may
          purchase  securities  subject to repurchase  agreements under policies
          established by the Trustees.
   
     13.  Invest  in  foreign   securities  (ADRs  are  not  considered  foreign
          securities)  in excess of ten percent  (10%) of the value of its total
          assets.  The Mid-Cap Stock Fund may invest up to  twenty-five  percent
          (25%) of the value of its total assets in foreign securities.
    
Except for the  limitations  on borrowing  from banks,  if the above  percentage
restrictions  are  adhered to at the time of  investment,  a later  increase  or
decrease in such  percentage  resulting from a change in values of securities or
amount of net assets will not be  considered a violation of any of the foregoing
restrictions.
   
The Money Market Fund may not write put or call options,  purchase  common stock
or other equity  securities or purchase  securities on margin or sell short. The
Treasury 2000, Bond,  Balanced,  Growth and Income Stock,  Capital  Appreciation
Stock,  and Mid-Cap  Stock Funds may not purchase  securities  on margin or sell
short. However, each Fund may obtain such short-term credits as may be necessary
for the  clearance of  transactions  and may make margin  payments in connection
with  transactions in futures and related options as permitted by its investment
policies.
    
                               PORTFOLIO TURNOVER

While the Money Market Fund is not subject to specific restrictions on portfolio
turnover, it generally does not seek profits by short-term trading.  However, it
may dispose of a portfolio  security  prior to its  maturity  where  disposition
seems  advisable  because of a revised credit  evaluation of the issuer or other
considerations. Because money market instruments have short maturities, the Fund
expects to have a high portfolio turnover,  but since brokerage  commissions are
not customarily charged on money market instruments,  a high turnover should not
adversely affect Net Asset Value or net investment income.
   
The Treasury 2000, Bond, Balanced, Growth and Income Stock, Capital Appreciation
Stock,  and  Mid-Cap  Stock Funds will trade  whenever,  in  management's  view,
changes are appropriate to achieve the stated investment objectives.  Management
does not anticipate that unusual portfolio turnover will be required and intends
to keep such turnover to moderate levels  consistent with the objectives of each
Fund.  Although  management makes no assurances,  it is expected that the annual
portfolio  turnover rate will be generally less than 100%.  This would mean that
normally less than 100% of the securities  held by the Fund would be replaced in
any one year (excluding  turnover of securities having a maturity of one year or
less).
    
                             MANAGEMENT OF THE FUND

Ultra  Series Fund is governed by a Board of  Trustees.  The  Trustees  have the
duties and  responsibilities set forth under the applicable laws of the State of
Massachusetts,  including but not limited to the management  and  supervision of
the funds.

The board,  from time to time, may include  individuals  who may be deemed to be
affiliated  persons of CIMCO,  the funds' adviser.  At all times,  however,  the
majority of board members will not be affiliated with CIMCO or the funds.

The funds do not hold annual shareholder meetings, but may hold special meetings
for such purposes as electing or removing  board members,  changing  fundamental
policies, approving certain management contracts,  approving or amending a 12b-1
plan, or as otherwise required by the 1940 Act.

legal and  accounting  services,  mailing  and  printing  services,  custody and
transfer agent services,  etc. The Investment Adviser is CIMCO Inc. The Company,
and CUNA  Mutual  Investment  Corporation  each own a one-half  interest  in the
Investment  Adviser.  CUNA  Mutual  Insurance  Society is the sole owner of CUNA
Mutual Investment  Corporation.  CUNA Mutual Investment  Corporation is the sole
owner  of  CUNA  Brokerage  Services,  Inc.,  the  principal  underwriter.   The
Investment Adviser and the Ultra Series Fund have servicing  agreements with the
Company  and with CUNA  Mutual  Insurance  Society.  The Company and CUNA Mutual
Insurance  Society  entered into a permanent  affiliation  July 1, 1990.  At the
current  time,  all of the  directors of the Company are also  directors of CUNA
Mutual  Insurance  Society  and many of the  senior  executive  officers  of the
Company hold similar positions with CUNA Mutual Insurance Society.
   
The  Investment  Adviser,  pursuant to a Management  Agreement  effective May 1,
1997,  provides investment advice for each Fund and provides or arranges for the
provision of substantially  all other services required by the Ultra Series Fund
through services agreements with affiliated and unaffiliated  service providers.
Such services include all administrative,  accounting and legal services as well
as the services of custodians,  transfer agents and dividend  disbursing agents.
There are, however,  certain expenses that The Ultra Series Fund pays for itself
under the Management  Agreement.  These are: fees of the  independent  Trustees,
fees of the  independent  auditors,  interest on borrowings by a Fund, any taxes
that a Fund must pay, and any extraordinary expenses incurred by a Fund or Funds
not in the ordinary course of business.  As full  compensation for its services,
the Ultra Series Fund pays the  Investment  Adviser a unitary fee computed at an
annualized  percentage rate of the average value of the daily net assets of each
series as set forth in the table below:

     Mid-Cap Stock                                           1.00 %


The total fee paid to the Investment  Adviser during the years ended December 31
was as follows:

          1996                                 $2,094,152
          1997                                 $5,320,543
          1998                                 $12,547,473
    
The Investment Adviser makes the investment decisions and is responsible for the
investment and reinvestment of assets; performs research,  statistical analysis,
and continuous supervision of the Fund's investment portfolio;  furnishes office
space for the Ultra  Series  Fund;  provides  the  Ultra  Series  Fund with such
accounting data concerning the investment activities of the Ultra Series Fund as
is required to be prepared and files all periodic  financial reports and returns
required to be filed with the Securities and Exchange Commission ("SEC") and any
other regulatory agency;  continuously  monitors  compliance by the Ultra Series
Fund in its investment activities with the requirements of the Act and the rules
promulgated pursuant thereto; and renders to the Ultra Series Fund such periodic
and  special  reports as may be  reasonably  requested  with  respect to matters
relating to the duties of the Investment Adviser.
   
The  Adviser  contracts  with the Company to perform  some of these  services on
behalf  of the Ultra  Series  Fund in return  for a  portion  of the  investment
advisory fee. The Adviser paid  $447,362,  $1,268,229,  and $2,800,753 for those
services in 1996, 1997, and 1998, respectively.

The  Adviser  contracts  with CUNA  Mutual  Insurance  Society to  perform  cash
management and investment accounting services on behalf of the Ultra Series Fund
in return  for a portion  of the  investment  advisory  fee.  The  Adviser  paid
$19,711,   $16,404,  and  $0  for  those  services  in  1996,  1997,  and  1998,
respectively.

The  Management  Agreement  provides  that the  Investment  Adviser shall not be
liable to the Ultra Series Fund or any  shareholder for anything done or omitted
by it, or for any losses that may be sustained in the purchase,  holding or sale
of any security,  except for an act or omission  involving willful  misfeasance,
bad faith, gross negligence, or reckless disregard of the duties imposed upon it
by the Management Agreement.
    
                     MANAGEMENT AGREEMENTS WITH SUBADVISERS

As described in the  prospectus,  CIMCO  manages the assets of the Mid-Cap Stock
Fund using a "manager of managers"  approach under which CIMCO may allocate some
of the  fund's  assets  among  one or more  "specialist"  subadvisers  (each,  a
"Subadviser").

Even though Subadvisers have day-to-day  responsibility over the management of a
portion of the Mid-Cap Stock Fund, CIMCO retains the ultimate responsibility for
the  performance of these funds and will oversee the  Subadvisers  and recommend
their hiring, termination, and replacement.

CIMCO may, at some future time,  employ a  subadvisory  or "manager of managers"
approach to other new or existing funds in addition to the Mid-Cap Stock Fund.

As of  the  date  of the  prospectus,  Heartland  Advisors,  Inc.  is  the  only
subadviser managing some of the assets of the Mid-Cap Stock Fund. The prospectus
contains a  description  of Heartland and its fee for managing the assets of the
Mid-Cap Stock Fund.

The directors and principal officers of the Investment Adviser are as follows:

     Janice C.  Doyle                       Assistant Secretary
     Michael S.  Daubs                      Director and President
     Lawrence R.  Halverson                 Senior Vice President and Secretary
     Joyce A.  Harris                       Director and Chair
     James C.  Hickman                      Director
     Michael B.  Kitchen                    Director
     Daniel J.  Larson                      Vice President
     Thomas J.  Merfeld                     Vice President
     George A.  Nelson                      Director and Vice Chair
     Jeffrey B.  Pantages                   Senior Vice President
     Scott R.  Powell                       Vice President

CUNA Brokerage  Services,  Inc., 5910 Mineral Point Road, Madison, WI 53705-4456
is the Trust's principal underwriter.

                              EXPENSES OF THE FUND
   
The Money Market, Bond, Balanced,  Growth and Income Stock, Capital Appreciation
Stock, and Mid-Cap Stock Funds are currently  obligated to pay to the Investment
Adviser the Management Fee set forth in the Management Fee Table above.  As part
of its services, the Investment Adviser has agreed to provide or arrange to have
provided,  administrative services to each Fund. Currently, the Company provides
the Funds with administrative,  fund accounting, transfer agency and shareholder
services.  The Adviser pays the Company  .15% of the average  value of the daily
net assets for these services.

Prior to May 1, 1997, expenses which exceeded .65% of the average value of daily
net  assets of such Fund were  being  absorbed  by the  Company  pursuant  to an
Expense  Reimbursement  Agreement between the Company and the Ultra Series Fund.
For the year ended December 31, 1995, the Company  absorbed  $96,817 of ordinary
business  expense.  For the year ended  December  31,  1996,  no  expenses  were
absorbed by the  Company.  For the year ended  December  31,  1997,  $48,308 was
absorbed by the Company.
    
                        DISTRIBUTION PLAN AND AGREEMENT

The Ultra Series fund has adopted a Distribution  Plan pursuant to Rule 12b-1 of
the Act under which the Ultra Series Fund bears certain expenses relating to the
distribution  of Class C shares.  The  Distribution  Plan provides for the Ultra
Series Fund to pay CUNA Brokerage Services, Inc. a distribution fee equal, on an
annual basis, to 0.25% of the average daily net assets of each Fund attributable
to Class C shares. The distribution fee is calculated and accrued daily and paid
quarterly or at such other intervals as the Ultra Series Fund and CUNA Brokerage
Services,  Inc. agree.  The  distribution  fee is paid solely out of each Fund's
assets supporting Class C shares. This means that the net asset value of Class C
shares  reflects  the daily  accrual of the fee but that the net asset  value of
Class Z shares is not affected by the  distribution  fee and no distribution fee
is supported by assets of any Fund representing Class Z shares.

Under the Distribution Plan, CUNA Brokerage  Services,  Inc. receives the entire
amount  of the  distribution  fee and may  spend  any  amount of the fee that it
considers  appropriate  to finance any activity  that is  primarily  intended to
result in the sale of Class C shares or to service  Class C  shareholders.  CUNA
Brokerage Services,  Inc. does not have to spend all of the distribution fee and
can spend  more than the  amount of the fee to finance  activities  intended  to
result in the sale of Class C shares or to service Class C shareholders. If CUNA
Brokerage  Services,  Inc.  spends less than the entire amount of the fee in any
period,  it may keep the amounts not spent.  If CUNA  Brokerage  Services,  Inc.
spends more than the amount of the fee in any period, the Ultra Series Fund will
not reimburse CUNA Brokerage Services, Inc. for the difference.
   
Activities primarily intended to result in the sale of Class C shares or service
Class C shareholders include, among other: (a) compensation to employees of CUNA
Brokerage Services,  Inc.; (b) compensation to and expenses,  including overhead
and  telephone  expenses,  of CUNA  Brokerage  Services,  Inc.,  other  selected
broker-dealers,  and  insurance  companies  who engage in or support  activities
primarily  intended  to result  in the sale of Class C shares;  (c) the costs of
printing and distributing prospectuses, statements of additional information and
annual and  interim  reports of the Ultra  Series Fund for  prospective  Class C
shareholders;  (d) the  costs of  preparing,  printing  and  distributing  sales
literature  and  advertising  materials  attributable  to  Class C  shares;  (e)
expenses relating to the formulation and implementation of marketing  strategies
and  promotional  activities  relating  to Class C shares  such as  direct  mail
promotions  and  television,  radio,  newspaper,  magazine  and other mass media
advertising;  and (f) the costs of  obtaining  such  information,  analyses  and
reports  with  respect to  marketing  and  promotional  activities  and investor
accounts as the Ultra Series Fund may, from time to time, deem  advisable.  CUNA
Brokerage Services, Inc. did not incur any expenses in 1998 relating to the sale
of Class C shares.
    
The Distribution  Plan was initially  approved on October 29, 1996, by the Board
of Trustees of the Ultra Series Fund, including all disinterested  Trustees. The
Plan became  effective  May 1, 1997,  and  continues in effect from year to year
only so long as such  continuance is approved at least annually by the Trustees,
including a majority of the Trustees who are not  interested,  as defined by the
Act, and who have no direct or indirect  financial  interest in the operation of
the Plan or agreements related to it.

Any amendment which would materially  increase the amount which the Ultra Series
Fund may expend under the Plan requires approval by holders of a majority of the
outstanding  shares of the Ultra Series Fund. Any agreement  related to the Plan
may be terminated at any time,  upon sixty (60) days written notice to the other
party, by a vote of a majority of the  disinterested  Trustees,  or by vote of a
majority  of the  Trust's  outstanding  voting  securities.  In the  event of an
assignment, the Plan terminates automatically. As long as the Plan is in effect,
the selection and nomination of the  disinterested  Trustees of the Ultra Series
Fund are committed to the discretion of the disinterested Trustees.

                                 TRANSFER AGENT
   
CUNA Mutual Life Insurance Company, 2000 Heritage Way, Waverly, IA 50677, is the
transfer agent and dividend  disbursing  agent for the Fund. As transfer  agent,
CUNA Mutual  maintains  the  shareholder  records and  reports.  CIMCO pays CUNA
Mutual  Life  Insurance  Company  .15% of the  average  daily net assets for its
transfer  agency  services and other  services  described  in the Fund  Expenses
section above. 

                                   CUSTODIAN
    
State Street Bank and Trust Company,  225 Franklin Street,  Boston, MA 02110, is
the current  custodian for the securities and cash of the Ultra Series Fund. The
custodian  holds for the Ultra Series Fund all  securities and cash owned by the
Ultra  Series  Fund,  and  receives  for the Ultra  Series Fund all  payments of
income,   payments  of  principal  or  capital  distributions  with  respect  to
securities owned by the Ultra Series Fund. Also, the custodian  receives payment
for the shares  issued by the Ultra  Series  Fund.  The  custodian  releases and
delivers  securities  and cash upon proper  instructions  from the Ultra  Series
Fund.  Pursuant to and in furtherance of a Custody Agreement with the custodian,
the Ultra Series Fund uses automated  instructions  and a cash data entry system
to transfer monies to and from the Ultra Series Fund's account at the custodian.

                              INDEPENDENT AUDITORS

The  financial  statements  have  been  included  herein  and  elsewhere  in the
Registration  Statement in reliance upon the reports of KPMG Peat Marwick,  LLP,
4200 Norwest Center, 90 South Seventh Street, Minneapolis, MN 55402, independent
auditors,  and upon the  authority  of said firm as  experts in  accounting  and
auditing.

                                   BROKERAGE

It is the  policy  of the  Ultra  Series  Fund,  in  effecting  transactions  in
portfolio  securities,  to seek best  execution of orders at the most  favorable
prices. The determination of what may constitute best execution and price in the
execution  of a  securities  transaction  by  a  broker  involves  a  number  of
considerations,  including without  limitation,  the overall direct net economic
result  (involving  both price paid or received  and any  commissions  and other
costs paid), the efficiency with which the transaction is effected,  the ability
to  effect  the  transaction  at all  where  a  large  block  is  involved,  the
availability  of the  broker to stand  ready to  execute  potentially  difficult
transactions  in the future and the  financial  strength  and  stability  of the
broker.  Such  considerations  are  judgmental  and are weighed by management in
determining the overall reasonableness of brokerage commissions paid.
   
Subject to the foregoing, a factor in the selection of brokers is the receipt of
research  services,   analyses  and  reports  concerning  issuers,   industries,
securities,  economic  factors  and trends  and other  statistical  and  factual
information.  Any such research and other  statistical  and factual  information
provided  by brokers to the Ultra  Series  Fund,  or the  Investment  Adviser or
Sub-Adviser  ("Advisers"  for purposes of this section),  is considered to be in
addition to and not in lieu of services required to be performed by the Advisers
under its contract  with the Ultra Series Fund.  Research  obtained on behalf of
the Ultra  Series  Fund may be used by the  Advisers  in  connection  with other
clients  of the  Advisers.  Conversely,  research  received  from  placement  of
brokerage for other accounts may be used by the Advisers in managing investments
of the Ultra Series Fund. Therefore,  the correlation of the cost of research to
individual  clients  of the  Advisers,  including  the  Ultra  Series  Fund,  is
indeterminable  and cannot  practically be allocated among the Ultra Series Fund
and the Advisers'  other clients.  Consistent  with the above,  the Ultra Series
Fund may effect  principal  transactions  with a  broker-dealer  that  furnishes
brokerage  and/or  research  services,  or designate any such  broker-dealer  to
receive selling  commissions,  discounts or other allowances,  or otherwise deal
with any  broker-dealer,  in connection  with the  acquisition  of securities in
underwritings.  Accordingly,  the net prices or commission  rates charged by any
such  broker-dealer  may be greater than the amount another firm might charge if
the management of the Ultra Series Fund determines in good faith that the amount
of such net prices and commissions is reasonable in relation to the value of the
services and research  information  provided by such  broker-dealer to the Ultra
Series Fund. For the year ended December 31, 1996,  Capital  Appreciation  Stock
Fund paid $171,251, Growth and Income Stock Fund paid $336,331 and Balanced Fund
paid  $150,550 in brokerage  fees.  There were no  brokerage  fees paid by Bond,
Money Market,  or Treasury 2000 Funds in 1996.  For the year ended  December 31,
1997,  Capital  Appreciation  Stock Fund paid $186,338,  Growth and Income Stock
Fund paid $352,096 and Balanced Fund paid $92,415 in brokerage fees.  There were
no brokerage  fees paid by Bond,  Money Market,  or Treasury 2000 Funds in 1997.
For the year ended  December  31,  1998,  Capital  Appreciation  Stock Fund paid
$358,785,  Growth and Income Stock Fund paid  $372,675,  and Balanced  Fund paid
$117,875 in brokerage  fees.  There were no brokerage  fees paid by Bond,  Money
Market, or Treasury 2000 Funds in 1998.
    
The  Ultra  Series  Fund  expects  that  purchases  and  sales of  money  market
instruments usually will be principal transactions. Money market instruments are
normally  purchased  directly from the issuer or from an  underwriter  or market
maker for the securities.  There usually will be no brokerage  commissions  paid
for such purchases.  Purchases from  underwriters  will include the underwriting
commission or concession  and  purchases  from dealers  serving as market makers
will include the spread between the bid and asked price.  Where transactions are
made in the  over-the-counter  market,  the Ultra Series Fund will deal with the
primary  market  makers  unless  equal or more  favorable  prices are  otherwise
obtainable.
   
Where advantageous,  the Ultra Series Fund may participate with other clients of
the Advisers in "bunching  of trades"  wherein one purchase or sale  transaction
representing  several  different  client  accounts is placed with a broker.  The
Advisers have established  various policies and procedures that assure equitable
treatment of all accounts.
    
The policy with  respect to  brokerage  is and will be reviewed by the  Trustees
from time to time. Because of the possibility of further regulatory developments
affecting  the  securities  exchanges  and brokerage  practices  generally,  the
foregoing practices may be changed, modified or eliminated.

                           HOW SECURITIES ARE OFFERED

Shares of Beneficial Interest

The  Declaration  of Trust permits the Trustees to issue an unlimited  number of
full and  fractional  shares of  beneficial  interest  of the Trust  without par
value. Under the Declaration of Trust, the Trustees have the authority to create
and classify shares of beneficial  interest in separate series,  without further
action by shareholders. As of the date of this SAI, the Trustees have authorized
shares of the seven funds described in the prospectus.  Additional series and/or
classes may be added in the future. The Declaration of Trust also authorizes the
Trustees to classify and  reclassify  the shares of the Trust,  or new series of
the Trust,  into one or more  classes.  As of the date of this SAI, the Trustees
have authorized the issuance of two classes of shares of the fund, designated as
Class C and Class Z. Additional classes of shares may be offered in the future.

The shares of each class of each fund represent an equal proportionate  interest
in the  aggregate  net  assets  attributable  to that  class of that  fund.  The
different classes of a fund may bear different  expenses relating to the cost of
holding shareholder meetings  necessitated by the exclusive voting rights of any
class of shares.

Dividends  paid by each fund,  if any, with respect to each class of shares will
be calculated in the same manner,  at the same time and on the same day and will
be in the same amount,  except for differences resulting from the fact that: (i)
the  distribution and service fees relating to Class C or Class Z shares will be
borne  exclusively by that class; (ii) each of Class C shares and Class Z shares
will bear any other class expenses  properly  allocable to such class of shares,
subject to the  requirements  imposed by the Internal  Revenue  Service on funds
having  a  multiple-class  structure.  Similarly,  the NAV per  share  may  vary
depending on whether Class C shares or Class Z shares are purchased.

In the  event  of  liquidation,  shareholders  of each  class  of each  fund are
entitled to share pro rata in the net assets of the class of the fund  available
for distribution to these shareholders. Shares entitle their holders to one vote
per dollar  value of shares,  are freely  transferable  and have no  preemptive,
subscription  or  conversion  rights.  When  issued,  shares  are fully paid and
non-assessable, except as set forth below.

Share certificates will not be issued.

Limitation of Trustee and Officer Liability

The  Declaration  further  provides that the Trust shall  indemnify  each of its
Trustees and officers against  liabilities and expenses  reasonably  incurred by
them, in connection  with,  or arising out of, any action,  suit or  proceeding,
threatened against or otherwise  involving such Trustee or officer,  directly or
indirectly, by reason of being or having been a Trustee or officer of the Trust.
The Declaration does not authorize the Trust to indemnify any Trustee or officer
against any liability to which he or she would otherwise be subject by reason of
or for willful misfeasance, bad faith, gross negligence or reckless disregard of
such person's duties.

Limitation of Interseries Liability

All  persons  dealing  with a fund must  look  solely  to the  property  of that
particular  fund for the enforcement of any claims against that fund, as neither
the Trustees, officers, agents or shareholders assume any personal liability for
obligations entered into on behalf of a fund or the Trust. No fund is liable for
the  obligations of any other fund.  Since the funds use a combined  prospectus,
however,  it is possible that one fund might become liable for a misstatement or
omission in the prospectus  regarding  another fund with which its disclosure is
combined.  The Trustees have  considered this factor in approving the use of the
combined prospectus.

Pursuant to current  interpretations of the Act, the Company will solicit voting
instructions  from  owners  of  variable  annuity  or  variable  life  insurance
contracts  issued by it with respect to any matters that are presented to a vote
of shareholders.  Insurance  companies not affiliated with the CUNA Mutual Group
will generally follow similar  procedures.  On any matter submitted to a vote of
shareholders,  all shares of the Ultra  Series Fund then issued and  outstanding
and entitled to vote shall be voted in the aggregate and not by series or Class,
except for matters  concerning only a series or Class.  Certain matters approved
by a vote of the  shareholders  of the Ultra Series Fund may not be binding on a
series or Class whose  shareholders  have not approved such matter.  This is the
case if the  matter  affects  interests  of that  series or Class  which are not
identical with the interests of all other series and Classes such as a change in
investment  policy,  approval of the Investment  Adviser or a material change in
the  distribution  Plan  and  failure  by  the  holders  of a  majority  of  the
outstanding  voting securities of the series or Class to approve the matter. The
holder of each share of each  series or Class of stock of the Ultra  Series Fund
shall be  entitled  to one vote for each full  dollar  of net asset  value and a
fractional vote for each fractional  dollar of net asset value attributed to the
shareholder.
   
The Ultra  Series Fund is not required to hold annual  meetings of  shareholders
and  does  not  plan  to do so.  The  Trustees  may  call  special  meetings  of
shareholders for action by shareholder vote as may be required by the Act or the
Declaration  of Trust.  The Trustees  have the power to alter the number and the
terms of office of the Trustees,  and may lengthen their own terms or make their
terms of unlimited  duration and appoint their  successors,  provided  always at
least a majority of the Trustees  have been elected by the  shareholders  of the
Ultra Series Fund.  The  Declaration  of Trust  provides that  shareholders  can
remove  Trustees  by a vote of  two-thirds  of the  outstanding  shares  and the
Declaration of Trust sets out procedures to be followed.
    
Because  shares  of the  Ultra  Series  Fund are sold to the CUNA  Mutual  Group
separate  accounts,  qualified  retirement plans sponsored by CUNA Mutual Group,
unaffiliated insurance company separate accounts and qualified retirement plans,
it is  possible  that  material  conflicts  could  arise  among and  between the
interests of: (1) variable annuity contract owners (or participants  under group
variable annuity  contracts) and variable life insurance contract owners, or (2)
owners of variable  annuity and variable life insurance  contracts of affiliated
and  unaffiliated  insurance  companies and (3)  participants  in affiliated and
unaffiliated  qualified retirement plans. Such material conflicts could include,
for example,  differences in federal tax treatment of variable annuity contracts
versus  variable  life  insurance  contracts.  The  Ultra  Series  Fund does not
currently  foresee  any  disadvantage  to one  category of  investors  vis-a-vis
another  arising  from the fact  that the Ultra  Series  Fund's  shares  support
different  types of variable  insurance  contracts.  However,  the Ultra  Series
Fund's  Board of Trustees  will  continuously  monitor  events to  identify  any
potential  material  conflicts that may arise between the interests of different
categories or classes of investors and to determine what action,  if any, should
be taken to resolve such conflicts.  Such action may include redeeming shares of
the Ultra Series Fund held by one or more of the separate  accounts or qualified
retirement plans involved in any material irreconcilable conflict.

                           NET ASSET VALUE OF SHARES

Net Asset Value per share is calculated  each  Valuation Day. Net Asset Value is
determined  by  dividing  each  Fund's  total net assets by the number of shares
outstanding  at the time of  calculation.  Total net  assets are  determined  by
adding the total current value of portfolio securities,  cash, receivables,  and
other assets and  subtracting  liabilities.  Shares will be sold and redeemed at
the Net Asset  Value next  determined  after  receipt of the  purchase  order or
request for redemption.
   
The Net Asset Value of a share issued by the Bond,  Balanced,  Growth and Income
Stock,  Capital Appreciation Stock, and Mid-Cap Stock Funds was initially set at
$10.00 per share. The Net Asset Value of a share issued by the Money Market Fund
was  initially  set at $1.00 per share.  (See Money  Market Fund below.) The Net
Asset Value of a share of the Treasury  2000 Fund was initially set at $3.62 per
share.
    
Money Market Fund

The  Trustees  have  determined  that the best method  currently  available  for
determining the Net Asset Value is the amortized cost method.  The Trustees will
utilize this method  pursuant to Rule 2a-7 of the Act. The use of this valuation
method will be continuously  reviewed and the Trustees will make such changes as
may be necessary to assure that assets are valued  fairly as  determined  by the
Trustees in good  faith.  Rule 2a-7  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 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 market  quotations.  The Trustees
will consider  what steps should be taken,  if any, in the event of a difference
of more than 1/2 of one percent (1%)  between the two.  The  Trustees  will take
such steps as they consider appropriate, (e.g., redemption in kind or shortening
the average  portfolio  maturity)  to minimize  any  material  dilution or other
unfair  results  which might arise from  differences  between the two.  The Rule
requires that the Fund limit its  investments to instruments  which the Trustees
determine  will  present  minimal  credit risks and which are of high quality as
determined by a major rating agency,  or, in the case of any instrument  that is
not so rated, of comparable quality as determined by the Trustees. It also calls
for the Fund to maintain a dollar weighted average portfolio  maturity (not more
than 90 days)  appropriate  to its  objective of  maintaining a stable Net Asset
Value of $1.00 per share and  precludes  the purchase of any  instrument  with a
remaining  maturity of more than 397 days. Should the disposition of a portfolio
security result in a dollar weighted average portfolio  maturity of more than 90
days,  the Fund will invest its available  cash in such manner as to reduce such
maturity to 90 days or less as soon as reasonably practicable.

It is the normal practice of the Fund 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 Fund will
realize  the par value of the  security.  Under  the  amortized  cost  method of
valuation  traditionally  employed by institutions for valuation of money market
instruments,  neither  the  amount of daily  income  nor the Net Asset  Value is
affected by any unrealized appreciation or depreciation. In periods of declining
interest  rates,  the  indicated  daily yield on shares the Fund has computed by
dividing  the  annualized  daily  income by the Net Asset  Value will tend to be
higher than if the  valuation  were based upon market prices and  estimates.  In
periods of rising interest  rates,  the indicated daily yield on shares the Fund
has computed by dividing the annualized daily income by the Net Asset Value will
tend to be lower  than if the  valuation  were  based  upon  market  prices  and
estimates.
   
Treasury 2000, Bond,  Balanced,  Growth and Income Stock,  Capital  Appreciation
Stock, and Mid-Cap Stock Funds
    
Common stocks that are traded on an established exchange or over-the-counter are
valued  on the  basis of  market  price as of the end of the  Valuation  Period,
provided  that a market  quotation  is readily  available.  Otherwise,  they are
valued at fair value as  determined  in good faith by or at the direction of the
Trustees.

Stripped  Treasury   Securities,   long-term  straight  debt  obligations,   and
non-convertible  preferred  stocks are valued  using  readily  available  market
quotations,  if available.  When exchange quotations are used, the latest quoted
sale price is used. If an over-the-counter quotation is used, the last bid price
will normally be used. If readily available market quotations are not available,
these securities are valued at market value as determined in good faith by or at
the direction of the Trustees.  Readily  available market quotations will not be
deemed available if an exchange quotation exists for a debt security,  preferred
stock, or security  convertible  into common stock,  but it does not reflect the
true value of the Fund's holdings because sales have occurred infrequently,  the
market for the security is thin, or the size of the reported trade is considered
not comparable to the Fund's institutional size holdings. When readily available
market  quotations are not available,  the Fund will use an independent  pricing
service which provides valuations for normal institutional size trading units of
such  securities.  Such a service may utilize a matrix  system  which takes into
account appropriate factors such as institutional size trading in similar groups
of securities,  yield,  quality,  coupon rate, maturity,  type of issue, trading
characteristics  and  other  market  data  in  determining   valuations.   These
valuations are reviewed by the  Investment  Adviser.  If the Investment  Adviser
believes that evaluation  still does not represent a fair value, it will present
for approval of the Trustees  such other  valuation  as the  Investment  Adviser
considers to represent a fair value. The specific pricing service or services to
be used will be presented for approval of the Trustees.

Short-term  instruments  having  maturities  of sixty  (60) days or less will be
valued at amortized cost. Short-term  instruments having maturities of more than
sixty  (60) days will be valued  at  market  values or values  based on  current
interest rates.

Options,  stock index futures,  interest rate futures, and related options which
are traded on U.S.  exchanges or boards of trade are valued at the closing price
as of the close of the New York Stock Exchange.

The Investment Adviser,  at the direction of the Trustees,  values the following
at prices it deems in good faith to be fair:

     1.   Securities  (including  restricted   securities)  for  which  complete
          quotations are not readily available, and

     2.   Listed  securities if, in the opinion of the Investment  Adviser,  the
          last sale price does not  reflect the  current  market  value or if no
          sale occurred, and

     3.   Other assets.

                       DIVIDENDS, DISTRIBUTIONS AND TAXES

The Fund  intends  that each of the Funds will  qualify each year as a regulated
investment company under Subchapter M of Chapter 1 of the Code. If, as intended,
each Fund continues to qualify as a regulated investment company and distributes
substantially  all of its net  investment  income and net  capital  gains to its
shareholders, then, under the provisions of Subchapter M, there should be little
or no income or gains  taxable to it. In  addition,  each Fund intends to comply
with other  distribution  rules specified in Code so that it will not incur a 4%
nondeductible federal excise tax that otherwise would apply.

Each Fund of the Trust must meet several  requirements to maintain its status as
a regulated investment company. These requirements include the following: (1) at
least 90% of the Fund's gross income must be derived from  dividends,  interest,
payments  with  respect  to  securities  loaned,  and  gains  from  the  sale or
disposition  of  securities;  and (2) at the close of each quarter of the Fund's
taxable  year,  (a) at least 50% of the value of the Fund's  total  assets  must
consist of cash, U.S.  Government  securities and other securities (no more than
5% of the value of the Fund may  consist  of such  other  securities  of any one
issuer, and the Fund must not hold more than 10% of the outstanding voting stock
of any  issuer),  and (b) the Fund must not invest more than 25% of the value of
its total assets in the securities of any one issuer (other than U.S. Government
securities).

Each of the Funds also intends to comply with section 817(h) of the Code and the
regulations issued thereunder,  which impose certain investment  diversification
requirements on separate  accounts of life insurance  companies that are used to
support variable annuity  contracts ("VA contracts") and variable life insurance
policies ("VLI policies").  In general, these requirements are that no more than
55% of the  value  of  the  assets  of a Fund  may  be  represented  by any  one
investment;  no more  than 70% by any two  investments;  no more than 80% by any
three  investments;  and no more  than 90% by any four  investments.  For  these
purposes,  all securities of the same issuer are treated as a single  investment
and each United  States  government  agency or  instrumentality  is treated as a
separate  issuer.  These  diversification  requirements  are in  addition to the
requirements  of subchapter M and of the Investment  Company Act, and may affect
the  securities in which a Fund may invest.  In order to comply with the current
or future  requirements  of section 817(h) (or related  provisions of the Code),
the Trust may be required,  for example,  to alter the investment  objectives of
one or more of the Funds. (To the extent required by law,  approval of owners of
VA  contracts  or VLI  policies or of the  Commission  will be  obtained  before
changing investment objectives.)

If a Fund fails to qualify as a regulated investment company, it will be subject
to federal, and possibly state,  corporate taxes on its taxable income and gains
(without  any  deduction  for  its   distributions  to  its   shareholders)  and
distributions to its shareholders will constitute  ordinary income to the extent
of such Fund's  available  earnings and profits.  Owners of VA contracts and VLI
policies  indirectly  invested  in such a Fund might be taxed  currently  on the
investment  earnings  under their  contracts  or policies  and thereby  lose the
benefit  of tax  deferral.  In  addition,  if a Fund  fails to  comply  with the
diversification  requirements  of section 817(h) of the Code and the regulations
thereunder,  owners of VA contracts and VLI policies  indirectly invested in the
Fund would be taxed on the investment earnings under their contracts or policies
and thereby lose the benefit of tax deferral.  Accordingly,  compliance with the
above  rules is  carefully  monitored  by the  investment  adviser and the Trust
intends  that each Fund  comply with these rules as they exist or as they may be
modified from time to time. Compliance with the tax requirements described above
may result in a reduction in the return under a Fund,  since, to comply with the
above rules,  the investments  utilized (and the time at which such  investments
are  entered  into and closed  out) may be  different  from what the  investment
adviser might otherwise believe desirable.

The foregoing  discussion of federal  income tax  consequences  is a general and
abbreviated  summary based on tax laws and  regulations in effect on the date of
this  SAI.  Tax law is  subject  to  change by  legislative,  administrative  or
judicial  action.  Each  prospective  investor should consult his or her own tax
adviser as to the tax  consequences of investments in the Funds. For information
concerning the federal income tax consequences to the owners of VA contracts and
VLI  policies,  see the  prospectuses  for  such  contracts  or  policies.  [For
information concerning the federal income tax consequences to plan participants,
see the summary plan description.]

It is the intention of the Ultra Series Fund to distribute  substantially all of
the net investment  income, if any, of each Fund thereby avoiding the imposition
of any Fund-level income or excise tax as follows:

     (i)  Dividends  on the  Money  Market  Fund  will  be  declared  daily  and
          reinvested  monthly in additional  full and  fractional  shares of the
          Money Market Fund.
   
     (ii) Dividends  of  ordinary  income  from the Bond,  Balanced,  Growth and
          Income Stock, and Capital  Appreciation Stock, and Mid-Cap Stock Funds
          will be declared  and  reinvested  quarterly  in  additional  full and
          fractional shares of the respective Fund.
    
     (iii)All net realized  short-term and long-term  capital gains of the Ultra
          Series  Fund,  if any,  will be  declared  and  distributed  at  least
          annually,  but in any event, no more frequently than allowed under SEC
          rules,  to the  shareholders  of each  Fund to which  such  gains  are
          attributable.

     (iv) Dividends on the Treasury 2000 Fund cannot be paid to its shareholders
          (the Separate  Accounts) during the taxable year since no cash will be
          available for  distribution  until the  securities are sold or mature.
          The Fund is  treated  as if it paid a  dividend  of a  certain  amount
          without  actually paying the dividend if the  shareholder  consents to
          the treatment ("consent dividend").  The Separate Accounts will file a
          consent on Form 972 each year to include in gross income, as a taxable
          dividend for that year, an amount  computed to be sufficient to enable
          the Fund to meet the distribution  requirements necessary for the Fund
          to be  treated  as a  conduit  and  taxed  as a  regulated  investment
          company.

          Because there will be no periodic  payment of interest on the Stripped
          Treasury  Securities  held by the  Treasury  2000  Fund,  shareholders
          (i.e.,  the separate  accounts or  qualified  plans) will be requested
          periodically to sign consents to have a certain portion of the accrued
          amount of  discount  treated  as  dividends.  Currently  the  separate
          accounts are the only  shareholders  of the Treasury  2000 Fund; it is
          anticipated  that any taxable income will be offset by a corresponding
          deduction for an increase in reserves.

Options and Futures Transactions

The tax  consequences of options  transactions  entered into by a Fund will vary
depending  on the  nature of the  underlying  security,  whether  the  option is
written or  purchased  and  finally,  whether the  "straddle"  rules,  discussed
separately below,  apply to the transaction.  When a Fund writes a call or a put
option on an equity or  convertible  debt  security,  the  treatment for federal
income  tax  purposes  of the  premium  that it  receives  will,  subject to the
straddle rules, depend on whether the option is exercised. If the option expires
unexercised, or if the Fund enters into a closing purchase transaction, the Fund
will  realize a gain (or loss if the cost of the  closing  purchase  transaction
exceeds the amount of the premium) without regard to any unrealized gain or loss
on the  underlying  security.  Any such gain or loss will be short-term  capital
gain or loss,  except that any loss on a  "qualified"  covered call stock option
that is not treated as part of a straddle  may be treated as  long-term  capital
loss. If a call option written by a Fund is exercised, the Fund will recognize a
capital gain or loss from the sale of the  underlying  security,  and will treat
the  premium as  additional  sales  proceeds.  Whether  the gain or loss will be
long-term  or  short-term  will depend on the holding  period of the  underlying
security.  If a put  option  written by a Fund is  exercised,  the amount of the
premium will reduce the tax basis of the security that the Fund then purchases.

If a put or call option that a Fund has  purchased  on an equity or  convertible
debt security expires unexercised, the Fund will realize a capital loss equal to
the cost of the option.  If the Fund enters into a closing sale transaction with
respect to the option,  it will  realize a capital  gain or loss  (depending  on
whether the proceeds from the closing  transaction  are greater or less than the
cost of the option).  The gain or loss will be short-term or long-term depending
on the Fund's  holding  period in the option.  If the Fund  exercises such a put
option,  it will realize a short-term  gain or loss (long-term if the Fund holds
the underlying security for more than one year before it purchases the put) from
the sale of the underlying  security measured by the sales proceeds decreased by
the premium paid. If the Fund exercises such a call option, the premium paid for
the option will be added to the tax basis of the security purchased.

One or more Funds may invest in Section 1256  contracts.  Section 1256 contracts
generally   include  options  on  nonconvertible   debt  securities   (including
securities of U.S. Government agencies or  instrumentalities),  options on stock
indexes,  futures  contracts,  options on futures  contracts and certain foreign
currency  contracts.  Options on foreign currency,  futures contracts on foreign
currency,  and options on foreign  currency futures will qualify as Section 1256
contracts  if the  options or futures are traded on or subject to the rules of a
qualified board or exchange.  In general, gain or loss on Section 1256 contracts
will be  treated  as 60%  long-term  and  40%  short-term  capital  gain or loss
("60/40"),  regardless of the period of time  particular  positions are actually
held by a Fund. In addition,  any Section 1256 contracts held at the end of each
taxable  year (and on October 31 of each year for  purposes of  determining  the
amount of capital gain net income that a Fund must distribute to avoid liability
for the 4% excise  tax) are "marked to market"  with the result that  unrealized
gains or losses are treated as though they were realized and the resulting  gain
or loss is treated as 60/40 gain or loss.

Straddles

Hedging transactions  undertaken by a Fund may result in "straddles" for federal
income tax purposes.  Straddles are defined to include "offsetting positions" in
actively-traded personal property. Under current law, it is not clear under what
circumstances  one  investment  made by a Fund,  such as an  option  or  futures
contract,  would be treated as "offsetting"  another investment also held by the
Fund, such as the underlying  security (or vice versa) and,  therefore,  whether
the Fund  would be  treated  as having  entered  into a  straddle.  In  general,
investment positions may be "offsetting" if there is a substantial diminution in
the risk of loss from  holding  one  position  by reason of holding  one or more
other positions (although certain "qualified" covered call stock options written
by a Fund may be treated as not creating a straddle).

To the extent that the straddle rules apply to positions  established by a Fund,
losses  realized  by the Fund  may be  either  deferred  or  recharacterized  as
long-term  losses,  and long-term gains realized by the Fund may be converted to
short-term gains.

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

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

Distributor
   
As described  in the  Prospectus,  the Ultra Series Fund does not deal  directly
with the  public.  Shares of the Ultra  Series  Fund are  currently  issued  and
redeemed through the distributor,  pursuant to a Distribution  Agreement between
the Ultra Series Fund and the  distributor.  The principal  place of business of
CUNA Brokerage  Services,  Inc. is 5910 Mineral Point Road,  Madison,  Wisconsin
53705. The distributor is owned by CUNA Mutual  Investment  Corporation which in
turn is owned by CUNA  Mutual  Insurance  Society.  The  Company and CUNA Mutual
Insurance Society entered into an agreement of permanent  affiliation on July 1,
1990.  Shares of the Ultra Series Fund are  purchased  and redeemed at Net Asset
Value.  The  Distribution  Agreement  provides that the distributor will use its
best efforts to render  services to the Ultra Series Fund, but in the absence of
willful  misfeasance,  bad faith,  gross negligence or reckless disregard of its
obligations,  it will not be liable to the Ultra Series Fund or any  shareholder
for any error of  judgment  or mistake of law or any act or  omission or for any
losses  sustained by the Ultra Series Fund or its  shareholders.  CUNA Brokerage
has not received underwriting  commissions from the Ultra Series Fund for any of
the last three fiscal years.
    
                    CALCULATION OF YIELDS AND TOTAL RETURNS

From time to time, the Ultra Series Fund may disclose yields, total returns, and
other performance  data. Such performance data will be computed,  or accompanied
by performance  data computed,  in accordance with the standards  defined by the
SEC.  The Ultra Series Fund will not  disclose  performance  of the Ultra Series
Fund in separate  account sales  literature or advertising  without also showing
performance at the separate account level.

The Ultra  Series Fund may  distribute  sales  literature  showing  total return
performance.  Total return  calculations are based on historical results and are
not intended to indicate  future  performance.  Total return will vary over time
depending on market conditions, assets owned and operating expenses. Information
about the performance of the Ultra Series Fund is contained in the annual report
to shareholders  which may be obtained  without charge from the address shown on
the first page of this SAI.

Total return  figures  distributed by the Ultra Series Fund will show the change
in value of an  investment  in the Ultra  Series Fund from the  beginning of the
measuring period to the end of the measuring  period.  All dividends and capital
gains are assumed to be immediately  reinvested.  Average annual total return is
calculated  by  determining   the  growth  or  decline  in  value  of  a  $1,000
hypothetical  investment over a stated period and then  calculating the annually
compounded percentage rate that would have produced the same ending value if the
rate of growth or decline in value had been constant  during the entire  period.
The  actual  rate of growth or  decline  varies  over  time,  rather  than being
constant,  so actual  year-to-year  performance will be different from "average"
annual return.  The Ultra Series Fund will show average annual total returns for
1, 3, 5, and 10 year periods (or, if shorter,  the period since  inception)  and
may show actual and average  total returns for other  periods.  The Ultra Series
Fund may also show cumulative return,  computed by dividing the value at the end
of the period by the value at the  beginning  of the  period.  Cumulative  total
return  may be  shown  either  as a  percentage  change  or as a  dollar  value.
Performance  data  may be  shown  in the  form of  graphs,  charts,  tables  and
numerical examples.

The Ultra Series Fund may also distribute sales literature showing yield figures
for its Money  Market and Bond  Funds.  Yield  figures  are based on  historical
earnings and are not intended to indicate future  performance.  The yield of the
fund refers to the income generated by an investment in the fund over the stated
period. This income is then annualized,  that is, the amount of income generated
by the  investment  during that period is assumed to be generated over a 365-day
period and is shown as a percentage of the  investment.  The effective  yield is
calculated  similarly but, when  annualized,  the income earned is assumed to be
reinvested or "compounded." The effective yield will be slightly higher than the
yield because of the effect of assumed reinvestment.

The Ultra  Series  Fund may  distribute  sales  literature  comparing  its total
returns to standard  industry  measures,  for example,  the Dow Jones Industrial
Average,  one or more of the Standard & Poor's or Frank  Russell  Company  stock
indexes,  one or more of the Lehman  Brothers bond indexes,  the consumer  price
index, and data published by Lipper Analytical Services,  Morningstar, Inc., and
Ibbotson  Associates.  The Dow  Jones  Industrial  Average  (DJIA)  is a  market
value-weighted,  unmanaged index of 30 large industrial stocks traded on the New
York Stock  Exchange.  The Standard and Poor's and Frank  Russell  Company stock
indexes are  unmanaged,  market value  weighted  indexes of various  industrial,
transportation,  utility  and  financial  companies,  grouped  by size of market
capitalization,  valuation  characteristics  (i.e.  growth  or  value)  or other
attributes. The Lehman Brothers bond indexes represent unmanaged groups of fixed
income   securities  of  various   issuers  and  terms  to  maturity  which  are
representative  of bond  market  performance.  The  consumer  price  index  is a
statistical  measure of changes  in the prices of goods and  services  over time
published by the U.S. Bureau of Labor Statistics. Lipper Analytical Services and
Morningstar,  Inc. are independent  services that monitor  performance of mutual
funds and  insurance  company  separate  accounts.  Lipper  Performance  Summary
Averages  represent  the average  annual total return of all the funds (within a
specified  investment  category)  that  are  covered  by the  Lipper  Analytical
Services Variable Insurance Products Performance Analysis Service.

The  volatility  of each fund may be compared to the  volatility of the relevant
market as a whole.  "Beta" is a measure of the sensitivity of a particular asset
or a particular fund relative to the marketplace in which it is traded. The beta
of the  market  is 1.0 which  serves  as a  benchmark  to  assess  other  assets
including  the six funds within the Ultra Series Fund.  Beta is a measure of the
degree to which the  return on the asset or the fund moved  relative  to how the
return of the relevant  market  moved.  A number that is both  positive and less
than 1.0 means that the asset or fund moved in the same  direction as the market
but to a smaller degree.  In other words, a beta of less than 1.0 indicates less
volatility (less investment risk) than the market.

Standard  deviation  measures the volatility of actual periodic returns around a
statistically  fitted (average) trendline of the actual returns.  For example, a
portfolio that grew over a five-year period at an average annual total return of
10% with a standard  deviation of 15% would be much more volatile (would involve
more  investment  risk) than a portfolio  that grew at an average  annual  total
return of 8% with a standard  deviation of 5%. The latter  portfolio  might meet
the investment needs of a risk averse investor better than the former portfolio.

Money Market Fund Yields

From time to time,  sales  literature may quote the current  annualized yield of
the Money  Market  Fund for a seven-day  period in a manner  which does not take
into  consideration  any  realized or  unrealized  gains or losses on  portfolio
securities.

This  current  annualized  yield  is  computed  by  determining  the net  change
(exclusive of realized gains and losses on the sale of securities and unrealized
appreciation  and  depreciation)  at the end of the  period  in the  value  of a
hypothetical account having a balance of 1 share at the beginning of the period,
dividing  such net  change in  account  value by the  value of the  hypothetical
account at the beginning of the period to determine the base period return,  and
annualizing  this quotient on a 365-day basis.  The net change in value reflects
net income from the Fund attributable to the hypothetical account.
Current yield is calculated according to the following formula:

Current Yield = [(NCS - ES)/UV) X (365/7)] x 100

Where:

     NCS= the net change in the value of the Money  Market  Fund  (exclusive  of
          realized  gains or losses  on the sale of  securities  and  unrealized
          appreciation and depreciation)  for the seven-day period  attributable
          to a hypothetical account having a balance of 1 share.

     ES=  per share expenses  attributable to the  hypothetical  account for the
          seven-day period.

     UV=  the share value at the close of business on the day prior to the first
          day of the seven-day period.

Effective yield = [(1 + ((NCS-ES)/UV)) 365/7 - 1] x 100

Where:

     NCS= the net change in the value of the Money  Market  Fund  (exclusive  of
          realized  gains or losses  on the sale of  securities  and  unrealized
          appreciation and depreciation)  for the seven-day period  attributable
          to a hypothetical account having a balance of 1 share.

     ES   = per share expenses  attributable to the hypothetical account for the
          seven-day period.

     UV   = the  share  value at the close of  business  on the day prior to the
          first day of the seven-day period.

The  current  and  effective  yields on amounts  held in the Money  Market  Fund
normally  fluctuate on a daily basis.  Therefore,  the  disclosed  yield for any
given past period is not an  indication  or  representation  of future yields or
rates of return.  The Money Market Fund's actual yield is affected by changes in
interest rates on money market securities, average portfolio maturity, the types
and quality of  portfolio  securities  held and  operating  expenses.  Yields on
amounts held in the Money Market Fund may also be  presented  for periods  other
than a seven-day period.

Other Fund Yields

From time to time,  sales  literature may quote the current  annualized yield of
one or more of the Funds  (except the Money Market Fund) for 30-day or one-month
periods.  The annualized  yield of a Fund refers to income generated by the Fund
during a 30-day or one-month  period and is assumed to be generated  each period
over a 12-month period.

The yield is computed by: 1) dividing the net investment  income of the Fund for
the period;  by 2) the maximum  offering  price per share on the last day of the
period times the daily average number of shares  outstanding for the period;  by
3) compounding  that yield for a six-month  period;  and by 4) multiplying  that
result by 2. The  30-day  or  one-month  yield is  calculated  according  to the
following formula:

Yield = [2 X (((NI - ES)/(U X UV)) + 1)6 - 1)] x 100

Where:

     NI   =  net  income  of  the  Fund  for  the  30-day  or  one-month  period
          attributable to the Fund's shares.

     ES   = expenses of the Fund for the 30-day or one-month period.

     U    = the average number of shares outstanding.

     UV   = the  share  value at the  close of the  last  day in the  30-day  or
          one-month period.

The yield normally fluctuates over time. Therefore,  the disclosed yield for any
given past period is not an  indication  or  representation  of future yields or
rates of return.  A Fund's  actual yield is affected by the types and quality of
portfolio securities held and operating expenses.

Average Annual Total Returns

From time to time,  sales literature may also quote average annual total returns
for one or more of the Funds for various periods of time.

When a Fund has been in operation for 1, 3, 5, and 10 years,  respectively,  the
average  annual total return for these periods will be provided.  Average annual
total  returns  for  other  periods  of time  may,  from  time to time,  also be
disclosed.

Standard  average annual total returns  represent the average annual  compounded
rates of  return  that  would  equate  an  initial  investment  of $1,000 to the
redemption  value of that  investment as of the last day of each of the periods.
The ending date for each period for which total return  quotations  are provided
will  be  for  the  most  recent  month  or  calendar  quarter-end  practicable,
considering  the type of the  communication  and the media  through  which it is
communicated.

The total return is calculated according to the following formula:

TR   = [((ERV/P)1/N) - 1] x 100

Where:

     TR   = the average annual total return net of any Fund recurring charges.

     ERV  = the ending  redeemable value of the hypothetical  account at the end
          of the period.

     P=   a hypothetical initial payment of $1,000.

     N    = the number of years in the period.

Other Total Returns

From time to time, sales  literature may also disclose  cumulative total returns
in conjunction with the standard  formats  described above. The cumulative total
returns will be calculated using the following formula:

CTR  = [(ERV/P) - 1] x 100

Where:

     CTR= The cumulative total return net of any Fund recurring  charges for the
          period.

     ERV  = The ending  redeemable value of the  hypothetical  investment at the
          end of the period.

     P=   A hypothetical single payment of $1,000.

  ***This security is non-income producing.

****This security provides a claim on the interest component of the underlying
mortgages, but not on their principal component. That is, the security's cash
flows depend on the amount of principal outstanding at the payment date. If
prepayments on the underlying mortgages are higher than expected, the yield on
the security may be adversely affected.

(A)  Represents a security that remains zero coupon until a predetermined date,
     at which the stated coupon rate becomes the effective rate.

(B)  Restricted security sold within the terms of a private placement memorandum
     exempt from registration under section 144A of the Securities Act of 1933,
     as amended, and maybe sold only to dealers in that program or other
     "qualified institutional investors." On December 31, 1998, the total market
     value of these investments was $25,926,193 or 5.8% of total net assets.

(C) Represents a security whose interest rate increases at predetermined dates.
The rate disclosed is the rate currently in effect.

  Gross unrealized appreciation..................................... $1,826,875
  Gross unrealized depreciation.................................... (1,491,069)
                                                                      ---------

***This security provides a claim on the interest component of the underlying
mortgages, but not on their principal component. That is, the security's cash
flows depend on the amount of principal outstanding at the payment date. If
prepayments on the underlying mortgages are higher than expected, the yield on
the security may be adversely affected.

(B)  Restricted security sold within the terms of a private placement memorandum
     exempt from registration under section 144A of the Securities Act of 1933,
     as amended, and maybe sold only to dealers in that program or other
     "qualified institutional investors." On December 31, 1998, the total market
     value of these investments was $27,812,875 or 12.2% of total net assets.

(C) Represents a security whose interest rate increases at predetermined dates.
The rate disclosed is the rate currently in effect.

** During the periods shown, prior to May 1, 1997, CUNA Mutual Life Insurance
   Company and its affiliates absorbed certain expenses under the terms of an

                                ULTRA SERIES FUND
                          Notes to Financial Statements

(1)  Description of the Fund

     The Ultra Series Fund (the "Fund"), a Massachusetts Business Trust, is
     registered under the Investment Company Act of 1940 (the "1940 Act"), as
     amended, as a diversified, open-end management investment company. The Fund
     is a series fund with six investment portfolios (the "funds"), each with
     different investment objectives and policies and each having available two
     separate classes of common stock with a par value of $.01 per share. Fund
     shares are sold and redeemed at a price equal to the shares' net asset
     value. The assets of each fund are held separate from the assets of the
     other funds.

     Effective May 1, 1997, the shares of each fund were divided into Class Z
     and Class C Shares. Class Z Shares are offered to all insurance company
     separate accounts issued by, and all qualified retirement plans sponsored
     by, CUNA Mutual Life Insurance Company or its affiliates ("CUNA Mutual
     Life"). Class C Shares are offered to separate accounts of insurance
     companies other than CUNA Mutual Life, and to qualified retirement plans of
     companies not affiliated with the Fund or CUNA Mutual Life. Both classes of
     shares are identical in all respects except that: Class C Shares may be
     subject to a distribution fee (note 4); each class will have exclusive
     voting rights with respect to matters that affect just that class; and each
     class will bear a different name or designation. All income earned and
     expenses incurred by the Fund are borne on a pro-rata basis by each
     outstanding share of each class based on the daily net asset value of
     shares of that class. As of December 31, 1998, no Class C Shares have been
     issued.

(2)  Significant Accounting Policies

     (a) Valuation of Investment Securities

         Portfolio securities for which market quotations are readily available
         are valued at current market value. If market quotations or valuations
         are not available, or if such quotations or valuations are believed to
         be inaccurate, unreliable or not reflective of market value, portfolio
         securities are valued according to procedures adopted by the funds'
         board of trustees in good faith at fair value.

         Pricing services value domestic and foreign equity securities (and
         occasionally fixed-income securities) traded on a securities exchange
         or Nasdaq at the last reported sale price, up to the time of valuation.
         If there are no reported sales of a security on the valuation date, it
         is valued at the mean between the published bid and asked prices
         reported by the exchange or Nasdaq. If there are no sales and no
         published bid and asked quotations for a security on the valuation date
         or the security is not traded on an exchange or Nasdaq, the pricing
         service may obtain market quotations directly from broker-dealers.

         Fixed-income securities are valued at prices obtained from a pricing
         service, when such prices are available. In circumstances where prices
         are not available from the fund's pricing service, securities may be
         valued using market quotations obtained from one or more dealers or a
         quotation system. Short-term securities with maturities of 60 days or
         less are valued at amortized cost, which approximates market value.

     (b) Share Valuation and Dividends to Shareholders

         The net asset value of the shares of each fund is determined on a daily
         basis based on the valuation of the net assets of the funds divided by
         the number of shares of the fund outstanding. Expenses, including the
         investment advisory, advisory/administrative, and distribution fees
         (note 4), are accrued daily and reduce the net asset value per share.

         Dividends on the Money Market Fund will be declared and reinvested
         daily in additional full and fractional shares of the Money Market
         Fund. Dividends of ordinary income from the Capital Appreciation Stock
         Fund, Growth and Income Stock Fund, Bond Fund, and Balanced Fund will
         be declared and reinvested quarterly in additional full and fractional
         shares of the respective funds. All net realized capital gains of these
         funds, if any, will be declared and reinvested at least annually. The
         Treasury 2000 Fund will utilize an annual consent dividend procedure
         which provides the fund with the deduction for dividends constructively
         paid to shareholders.

     (c) Federal Income Taxes

         Each fund intends to distribute all of its taxable income and to comply
         with the other requirements of the Internal Revenue Code applicable to
         regulated investment companies. Accordingly, no provision for income or
         excise taxes is required.

         Net investment income and net realized gains (losses) for the funds may
         differ for financial statement and tax purposes. The character of
         distributions made during the year from net investment income or net
         realized gains may differ from their ultimate characterization for
         federal income tax purposes. Also, due to the timing of dividend
         distributions, the fiscal year in which amounts are distributed may
         differ from the year that the income or realized gains (losses) were
         recorded by the funds.
<PAGE>
         For federal income tax purposes, at December 31, 1998, the Balanced
         Fund had a capital loss carryover of $2,476,442 that will expire in the
         year 2006 if not offset by subsequent capital gains. It is unlikely
         that the Board of Trustees will authorize a distribution of any net
         realized capital gains until the available capital loss carryover has
         been offset or expires.

         The statements of assets and liabilities, as a result of certain
         book-tax differences, reflect the following reclassification
         adjustments:

</TABLE>
      (d)Security Transactions and Investment Income

         Security transactions are recorded on the trade date basis. Realized
         gains and losses from security transactions are reported on the
         identified cost basis. Interest, including amortization of premium and
         discount, is accrued daily and dividend income is recorded on the
         ex-dividend date.

     (e) Use of Estimates

         The preparation of financial statements in conformity with generally
         accepted accounting principles requires management to make estimates
         and assumptions that affect the reported amounts of assets and
         liabilities and disclosure of contingent assets and liabilities at the
         date of the financial statements and the reported amounts of increase
         and decrease in net assets from operations during the period. Actual
         results could differ from those estimates.

(3)  Purchase and Sales of Investment Securities

     The cost of securities purchased and the proceeds from securities sold
     (including maturities, excluding short-term securities for all funds except
     Money Market) for each fund during the year ended December 31, 1998, were
     as follows:

     Fees and Expenses

     The Fund has entered into an investment advisory agreement with CIMCO Inc.
     (the "Investment Adviser"), an affiliated company. The fees under the
     agreement, paid monthly, are calculated as a percentage of the average
     daily net assets for each portfolio at the following annual rates:

              Capital Appreciation Stock             0.80%
              Growth and Income Stock                0.60%
              Balanced                               0.70%
              Bond                                   0.55%
              Money Market                           0.45%
              Treasury 2000                          0.45%

     Under this unified fee structure, the Investment Adviser is responsible for
     providing or obtaining services and paying certain expenses including
     custodian fees, transfer agent fees, pricing costs, and accounting and
     legal fees as indicated in the investment advisory agreement.

     In addition to the unified investment advisory fee, each fund also pays
     certain expenses including trustees fees, brokerage commissions, interest
     expense, audit fees, and other extraordinary expenses.

                          Independent Auditors' Report

The Board of Trustees and Shareholders
Ultra Series Fund:

We have audited the accompanying statements of assets and liabilities, including
the schedules of investments in securities, of Capital Appreciation Stock Fund,
Growth and Income Stock Fund, Balanced Fund, Bond Fund, Money Market Fund and
Treasury 2000 Fund (funds within Ultra Series Fund) as of December 31, 1998, and
the related statements of operations for the year then ended, the statements of
changes in net assets for each of the years in the two-year period then ended
and the financial highlights for each of the years in the five-year period then
ended. These financial statements and the financial highlights are the
responsibility of the funds' management. Our responsibility is to express an
opinion on these financial statements and the financial highlights based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Investment securities held in custody are confirmed to us by the
custodian. As to securities purchased and sold but not received or delivered, we
request confirmations from brokers and, where replies are not received, we carry
out other appropriate auditing procedures. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Capital Appreciation Stock Fund, Growth and Income Stock Fund, Balanced Fund,
Bond Fund, Money Market Fund and Treasury 2000 Fund as of December 31, 1998, and
the results of their operations, the changes in their net assets and the
financial highlights for the periods stated in the first paragraph above, in
conformity with generally accepted accounting principles.

Item 25.  Indemnification

Each officer,  Trustee or agent of the Ultra Series Fund shall be indemnified by
the Ultra Series Fund to the full extent permitted under the General Laws of the
State of  Massachusetts  and the  Investment  Company  Act of 1940,  as amended,
except  that such  indemnity  shall not  protect  any such  person  against  any
liability  to the Ultra  Series  Fund or any  shareholder  thereof to which such
person 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 ("disabling conduct"). Indemnification shall be made when (1) a final
decision  on the  merits  is made by a court  or  other  body  before  whom  the
proceeding  was  brought,  that the person to be  indemnified  was not liable by
reason of  disabling  conduct  or,  (2) in the  absence  of such a  decision,  a
reasonable  determination,  based upon a review of the facts, that the person to
be indemnified was not liable by reason of disabling conduct, by (a) the vote of
a majority of the quorum of  Trustees  who are not  "interested  persons" of the
Ultra Series Fund as defined in Section  2(a)(19) of the Investment  Company Act
of 1940, or (b) an  independent  legal counsel in a written  opinion.  The Ultra
Series  Fund may,  by vote of a  majority  of a quorum of  Trustees  who are not
interested  persons,  advance  attorneys'  fees or other  expenses  incurred  by
officers, Trustees,  Investment Advisers or principal underwriters, in defending
a  proceeding  upon  the  undertaking  by or  on  behalf  of  the  person  to be
indemnified to repay the advance unless it is ultimately  determined  that he is
entitled to  indemnification.  Such advance  shall be subject to at least one of
the following: (1) the person to be indemnified shall provide a security for his
undertaking,  (2) the Ultra Series Fund shall be insured  against losses arising
by  reason  of  any  lawful  advances,  or (3) a  majority  of a  quorum  of the
disinterested  non-party  Trustees of the Ultra Series Fund,  or an  independent
legal  counsel  in a  written  opinion,  shall  determine,  based on a review of
readily  available facts,  that there is reason to believe that the person to be
indemnified ultimately will be found entitled to indemnification.

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

                                (April 13, 1999)

THIS  AGREEMENT  ("Agreement")  is made  this 13th day of  April,  1999,  by and
between CIMCO Inc., an Iowa corporation (the "Adviser"), and Heartland Advisors,
Inc. (the "Sub-Adviser"), a Wisconsin corporation.


1.       Representations.

         (a) Ultra  Series  Fund (the  "Trust")  is a  Delaware  business  trust
         organized  with one or more  series of shares and is  registered  as an
         open-end management investment company under the Investment Company Act
         of 1940, as amended (the "ICA").

         (b) The  Adviser  and the  Sub-Adviser  each is an  investment  adviser
         registered  under the Investment  Advisers Act of 1940, as amended (the
         "Advisers Act").

         (c) The Board of Trustees of the Trust (the  "Trustees")  have  engaged
         the  Investment  Adviser to act as  investment  adviser for the Mid-Cap
         Stock Fund (the "Portfolio"),  one series of the Trust, under the terms
         of a management agreement, dated February 7, 1997, with the Trust  (the
         "Management Agreement").

         (d) The Adviser, acting pursuant to the Management Agreement, wishes to
         engage the  Sub-Adviser,  and the Trustees have approved the engagement
         of the Sub-Adviser,  to provide  investment advice and other investment
         services set forth below.


2. Investment  Services.  The Adviser hereby engages the services of Sub-Adviser
in  connection  with  Adviser's  management of the  Portfolio.  Pursuant to this
Agreement and subject to the oversight  and  supervision  of the Adviser and the
Trustees,  the Sub-Adviser  shall manage the investment and reinvestment of that
portion  of  the  Portfolio  as  Adviser  shall  determine  from  time  to  time
(hereinafter referred to as the "Sub-Portfolio").

Adviser intends to use a  manager-of-managers  approach to manage the Portfolio.
The number of sub-advisers, the named sub-advisers, and the percentage of assets
of the Portfolio managed by each sub-adviser shall be determined by the Trustees
and the Adviser from time to time;  provided,  however, the Sub-Adviser shall be
given not less than  thirty  (30) days  advance  written  notice of all  changes
affecting this Agreement or the Sub-Adviser's role hereunder.

The Sub-Adviser  shall formulate and implement a continuous  investment  program
for  the  Sub-Portfolio  conforming  to  the  investment  objective,  investment
policies and  restrictions of the  Sub-Portfolio  as set forth in the Prospectus
and  Statement of Additional  Information  of the Fund as in effect from time to
time (together, the "Registration Statement"),  the Agreement and Declaration of
Trust and By-laws of the Fund, any investment  guidelines or other  instructions
received by the  Sub-Adviser  in writing  from the Adviser from time to time and
all applicable  securities laws and related  regulations.  Any amendments to the
foregoing  documents  (excluding  securities laws and  regulations)  will not be
deemed effective with respect to the Sub-Adviser until the Sub-Adviser's receipt
thereof.

The Adviser  acknowledges and agrees that the Sub-Adviser is hereby  authorized,
to freely  exercise on behalf of the Trust,  its rights as a shareholder  of the
various  companies  in which the  Sub-Portfolio  may invest  including,  but not
limited  to its right to,  (a)  communicate  its views on  matters  of policy to
management, the board of directors and other shareholders of a portfolio company
and (b) take such other steps, either individually or as part of a group, to (i)
influence a portfolio company's  decision-making process, (ii) seek changes in a
company's management or board of directors, (iii) effect the sale of all or some
of a  portfolio  company's  assets and (iv) vote to  participate  in or oppose a
takeover effort by or of a portfolio  company whenever the Sub-Adviser  believes
such  activities  may  affect  the  value of the  Trust's  investment  ("control
actions").  The Adviser  understands  that such control  actions could result in
additional expense to the Trust,  including expenses associated with operational
or  regulatory  requirements  and the ongoing cost of potential  litigation as a
plaintiff.  However, no expense shall be incurred without the written consent of
the Adviser.  The Adviser  further  understands  that such control  actions also
could  restrict  the  Trust's  ability to freely  trade in the  securities  of a
portfolio  company  with  respect  to which it is  deemed  to be  investing  for
control,  which  might  adversely  affect the Trust's  liquidity  as well as the
valuation  of those  securities.  Greater  public  disclosure  could be required
regarding the Trust's  investment and trading  strategies in regulatory  filings
relating to such securities.

The appropriate  officers and employees of the Sub-Adviser  will be available to
consult with the Adviser,  the Trust and the  trustees at  reasonable  times and
upon reasonable notice concerning the business of the  Sub-Portfolio,  including
valuations of securities which are not registered for public sale, not traded on
any  securities  market or otherwise may be deemed  illiquid for purposes of the
ICA; provided it is understood that the Sub-Adviser is not responsible for daily
pricing of the  Sub-Portfolio's  assets except for  recommending  to the Adviser
upon request proposed valuations for portfolio securities when market quotations
are not readily available.

Sub-Adviser  shall  not be  responsible  for the  provision  of  administrative,
bookkeeping or accounting services to the Portfolio or Sub-Portfolio,  except as
specifically  provided herein,  as required by the ICA or the Advisers Act or as
may be necessary for the Sub-Adviser to supply to the Adviser,  the Portfolio or
the  Portfolio's  shareholders  the  information  required to be provided by the
Sub-Adviser hereunder.  To the extent the Sub-Adviser agrees to perform any such
services,  they  shall  be  performed  based  upon the  books  and  records  the
Sub-Adviser maintains with respect to the Sub-Portfolio.  Any records maintained
hereunder  shall  be the  property  of the Fund and  surrendered  promptly  upon
request.


2.  Compliance  Monitoring and Reporting The parties  acknowledge and agree that
the Sub-Adviser shall not be the compliance agent or administrator for the Trust
or for the Adviser.  However,  the  Sub-Adviser  shall supervise and monitor the
activities of its  representatives,  personnel and agents in connection with the
investment program of the  Sub-Portfolio.  In furnishing the services under this
Agreement, the Sub-Adviser shall manage the Sub-Portfolio in accordance with the
requirements of: (i) the ICA and the regulations  promulgated  thereunder;  (ii)
Subchapters  L and M  (including,  respectively,  Section  817(h)  and  Sections
851(b)(1),  (2), (3), and (4) of the Internal  Revenue Code and the  regulations
promulgated  thereunder;  (iii) other applicable  provisions of state or federal
law; (iv) the Agreement and  Declaration of Trust and By-Laws of the Trust;  (v)
policies  and  determinations  of the  Trust  and the  Adviser  provided  to the
Sub-Adviser in writing;  (vi) the  fundamental  and  non-fundamental  investment
policies and restrictions as may be amended from time to time by the Portfolio's
shareholders or Trustees and  communicated to the Sub-Adviser in writing;  (vii)
the  Registration   Statement;   and  (viii)  investment   guidelines  or  other
instructions provided to the Sub-Adviser in writing from the Adviser.

Notwithstanding  the foregoing,  the Sub-Adviser shall have no responsibility to
monitor  compliance with limitations or restrictions for which  information from
the Adviser or its  authorized  agents is required to enable the  Sub-Adviser to
monitor compliance with such limitations or restrictions unless such information
is accurately, completely and timely provided to the Sub-Adviser in writing.

The  Sub-Adviser  shall be  responsible  for the  preparation  and filing of any
reports  required to be filed under  Sections  13 and 16 of the  Securities  and
Exchange Act of 1934,  as amended  (the "1934 Act") with  respect to  securities
held in the  Sub-Portfolio.  The  Sub-Adviser  shall not be responsible  for the
preparation  or  filing  of any  other  reports  required  of the  Portfolio  or
Sub-Portfolio  by any  governmental  or regulatory  agency,  except as expressly
agreed to in writing.

The  Adviser  and  Sub-Adviser  shall  cooperate  with each  other in  providing
information, reports and other materials to regulatory and administrative bodies
having proper jurisdiction over the Adviser,  the Sub-Adviser,  the Portfolio or
the Sub-Portfolio;  provided, however, that this agreement to cooperate does not
apply to the provision of information,  reports and other materials which either
of them reasonably  believes a regulatory or  administrative  body does not have
the authority to request or is the respective party's privileged or confidential
information.


3. Execution of Portfolio  Transactions.  Subject to the supervision and control
of the Adviser,  which in turn is subject to the  supervision and control of the
Trustees,  the  Sub-Adviser in its discretion  shall determine which issuers and
securities or other investments  shall be purchased,  held, sold or exchanged by
the  Sub-Portfolio or otherwise  represented in the  Sub-Portfolio's  investment
portfolio from time to time and,  subject to the provisions of this section 3 of
the Agreement, shall place orders with and give instructions to brokers, dealers
and others for all such transactions and cause such transactions to be executed.
Custody  of the  Sub-Portfolio  shall be  maintained  by a  custodian  bank (the
"Custodian")  designated  by the Trust,  and the  Adviser  shall  authorize  the
Custodian to honor  orders and  instructions  by  employees  of the  Sub-Adviser
designated  by  the  Sub-Adviser  to  settle  transactions  in  respect  of  the
Sub-Portfolio.  No assets may be withdrawn from the Sub-Portfolio other than for
settlement  of  transactions  on behalf of the  Sub-Portfolio,  except  upon the
written  authorization of appropriate  officers of the Trust who shall have been
certified as such by proper authorities of the Trust prior to the withdrawal.

In  connection  with  the  investment  and  reinvestment  of the  assets  of the
Sub-Portfolio,   the   Sub-Adviser   is   responsible   for  the   selection  of
broker-dealers to execute purchase,  sale,  exchange and other  transactions for
the Sub-Portfolio in conformity with the policy regarding brokerage as set forth
in the  Registration  Statement,  or as the Trustees may determine  form time to
time,  as well as the  negotiation  of  brokerage  commission  rates  with  such
executing broker-dealers.  Generally, the Sub-Adviser's primary consideration in
placing Sub-Portfolio  investment transactions with broker-dealers for execution
will be to obtain,  and maintain the availability of, best execution at the best
available price.

Consistent with this policy,  the Sub-Adviser,  in selecting  broker-dealers and
negotiating  brokerage  commission  rates,  will take all relevant  factors into
consideration,  including,  but not  limited to: the best price  available;  the
reliability,  integrity and financial  condition of the broker-dealer;  the size
and  difficulty  in  executing  the  order;   and  the  value  of  the  expected
contribution  of  the  broker-dealer  to  the  investment   performance  of  the
Sub-Portfolio on a continuing  basis.  Subject to such polices and procedures as
the Trustees may determine and  communicate in writing to the  Sub-Adviser,  the
Sub-Adviser  shall have  discretion to effect  investment  transactions  for the
Sub-Portfolio through broker-dealers (including, to the extent permissible under
applicable law,  broker-dealers  affiliated with the  Sub-Adviser)  qualified to
obtain  best  execution  of such  transactions  who  provide  brokerage  and /or
research  services,  as such  services are defined in section  28(e) of the 1934
Act, and to cause the Sub-Portfolio to pay any such  broker-dealers an amount of
commission for effecting a portfolio investment transaction,  if the Sub-Adviser
determines  in good  faith  that such  amount of  commission  is  reasonable  in
relation to the value of the  brokerage  or research  services  provided by such
broker-dealer,  viewed  in terms of either  that  particular  investment  or the
Sub-Adviser's  overall  responsibilities  with respect to the  Sub-Portfolio and
other accounts as to which the Sub-Adviser  exercises  investment  discretion as
such term is defined in section  3(a)(35) of the  Securities and Exchange Act of
1934 (the "1934 Act") (the "Separate  Accounts").  The Sub-Adviser  shall not be
required to use a broker-dealer  which provides research services to the Adviser
or other sub-advisers or to use a particular broker-dealer which the Adviser has
recommended.

On occasions when the Sub-Adviser deems the purchase or sale of a security to be
in the best interest of the  Sub-Portfolio  as well as other Separate  Accounts,
the Sub-Adviser,  in good faith and conformity with its  responsibilities  under
applicable  laws,  rules and  regulations  may,  but shall not be  required  to,
aggregate  the  securities  to be  purchased or sold to attempt to obtain a more
favorable  price or lower  brokerage  commissions  and  achieve  more  efficient
execution. In the event of such an allocation,  the allocation of securities and
the related  transaction  expenses  shall be made by the  Sub-Adviser  among the
Sub-Portfolio, the Portfolio and other clients of the Sub-Adviser in such manner
as the Sub-Adviser reasonably believes is fair and equitable and consistent with
its fiduciary obligations.


4. Proxy Voting; Class Actions. Unless the Adviser gives the Sub-Adviser written
instructions to the contrary,  the Sub-Adviser shall use its good faith judgment
in a manner  which it  reasonably  believes  best  serves the  interests  of the
Portfolio's shareholders to vote or abstain from voting all proxies solicited by
or  with  respect  to  the  issuers  of   securities  in  which  assets  of  the
Sub-Portfolio may be invested. Sub-Adviser's sole responsibility with respect to
matters of Class Actions  received by the Trust  relating to securities  held in
the  Sub-Portfolio  shall be to consult  with the  Adviser  and/or the  Trustees
regarding the merits thereof.


5. Reports by the Sub-Adviser.  The Sub-Adviser shall report to the Adviser with
such  frequency  and in such form as may be  mutually  agreed  from time to time
information  concerning  transactions  and  performance  of  the  Sub-Portfolio,
including  information  required in the  Registration  Statement or  information
necessary for the Adviser to review the  Sub-Portfolio or discuss the management
of it. The  Sub-Adviser  shall  permit  the books and  records  maintained  with
respect to the  Sub-Portfolio  to be  inspected  and  audited by the Trust,  the
Adviser  or their  respective  agents  at all  reasonable  times  during  normal
business hours upon reasonable  notice. The Sub-Adviser shall immediately notify
both the Adviser and the Trust of any legal process served upon it in connection
with its  activities  hereunder,  including any legal process  served upon it on
behalf of the  Adviser,  the  Portfolio  or the  Trust.  The  Sub-Adviser  shall
promptly  notify the Adviser of any  changes in any  information  regarding  the
Sub-Adviser or the investment  program for the Sub-Portfolio as described in the
Registration Statement.

6. Compensation of the Sub-Adviser. For the services rendered hereunder, Adviser
shall pay Sub-Adviser at the end of each month, a fee at the annual rate of 0.60
of the average daily net assets of the Sub-Portfolio.

Sub-Adviser's  fee shall be accrued  daily at 1/365th of the  applicable  annual
rate set forth above. For the purpose of accruing  compensation,  the net assets
of the  Sub-Portfolio  shall be  determined  by the  method and on the dates set
forth in the Trust's Registration  Statement,  as amended from time to time, and
in  accordance  with such  valuation  procedures  as adopted by the Fund. In the
event of termination of this Agreement, all compensation due through the date of
termination  shall  be  calculated  on a  pro-rated  basis  through  the date of
termination and paid within thirty business days of the termination date.

The  Adviser  and  the  Sub-Adviser  shall  not be  considered  as  partners  or
participants in a joint venture.  The  Sub-Adviser is an independent  contractor
and, unless otherwise expressly provided herein or otherwise  authorized,  shall
have no authority to act or represent the Adviser, the Trust or the Portfolio or
to otherwise act as agent for any of them.

The  Sub-Adviser  shall  provide the office  space,  furnishings,  equipment and
personnel  and shall pay such other of its  expenses  required  to  perform  the
services to be provided under this Agreement,  but shall not be obligated to pay
any expenses of the  Adviser,  the  Portfolio  or the Fund.  Except as otherwise
specifically  provided herein, the Adviser, the Portfolio and the Fund shall not
be obligated to pay any expenses of the Sub-Adviser.

9. Confidential Treatment. The parties hereto understand that any information or

its obligations  hereunder is to be regarded as confidential and for use only by
the Adviser,  the Trust or such persons the Adviser may  designate in connection
with the  Sub-Portfolio.  The  parties  also  understand  that  any  information

and warrants to the other that:  (i) it is registered  as an investment  adviser
under the Advisers Act; and (ii) it will promptly  notify the other if it ceases

12.  Liability.   The  federal  laws  impose   responsibilities   under  certain
circumstances  on persons who act in good faith,  and therefore,  nothing herein

Trust, the Portfolio or the Adviser may have under applicable law.


13. Other Activities of the Sub-Adviser. The Adviser agrees that the Sub-Adviser

Sub-Portfolio.  The Adviser further acknowledges that the Sub-Adviser and any of
its shareholders or employees, and persons affiliated with the sub-Adviser shall

for purchase or sale, for the  Sub-Portfolio any security which the Sub-Adviser,
its  shareholders,  employees or persons  affiliated  with the  Sub-Adviser  may
purchase  or sell for their own  respective  accounts  or for the account of any
other client of the Sub-Adviser,  advisory or otherwise, or (ii) to abstain from

the Adviser  pursuant to subparagraph  7(h) hereof for the  Sub-Adviser's  other

thereafter by specific  approval of the Trustees or by vote of a majority of the
outstanding  voting  securities  of the  Portfolio.  Any such  renewal  shall be
approved  by the  vote of a  majority  of the  Trustees  who are not  interested
persons under the ICA, cast in person (or as otherwise  permitted under the ICA)
at a meeting  called for the purpose of voting on such renewal.  This  Agreement
may be terminated  without penalty at any time by the Adviser or the Sub-Adviser
upon 60 days written notice,  and will  automatically  terminate in the event of

in the ICA,  subject to such  exemptions as may be granted by the Securities and
Exchange  Commission by rule,  regulation or order, or (ii) upon  termination of

of its duties or by reason of its  reckless  disregard  of its  obligations  and
duties under this Agreement.

It is agreed that the obligations of the  indemnifying  party under this section
shall  extend  to  expenses  and costs  (including  reasonable  attorneys  fees)
incurred by the indemnified  party as a result of any litigation  brought by the
indemnifying  party  alleging the  indemnified  party's-  failure to perform its
obligations  and  duties in the manner  required  under  this  Agreement  unless
judgment is rendered for the  indemnifying  party. It is further agreed that the
