                                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:

- -        require stability of principal

- -        are seeking a mutual fund for the cash portion of an asset allocation
         program

- -        need to "park" your money temporarily or

- -        consider yourself a saver rather than an investor.

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

- -        want federal deposit insurance

- -        are seeking an investment that is likely to outpace inflation

- -        are investing for retirement or other goals that are many years in the
         future or

- -        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.

                               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:

- -   desire an assured future value of a portion of your investments at a
    specified future date or

- -   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:

- -   want Federal deposit insurance

- -   are willing to assume some variability of future balance in pursuit of
    higher long term returns or

- -   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  that 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.


At a specific  time to be  determined  by the  Adviser, between  May 1, 2000 and
November 15, 2000,  the securities  held by the Fund will be liquidated.  As the
Fund liquidates the portfolio, it will invest the proceeds in securities similar
to those purchased by the Money Market Fund. On or before December 31, 2000, the
fund will distribute any remaining 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:

- -   seek an investment based on a regular stream of income

- -   seek higher potential returns than money market funds and are willing
    to accept moderate risk of volatility

- -   want to diversify your investments

- -   seek a mutual fund for the income portion of an asset allocation program or

- -   are retired or nearing retirement.

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

- -   invest for maximum return over a long time horizon or

- -   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.  The  CIMCO
management  team  utilizes an approach  that  involves  frequent  trading of the
securities in the  portfolio.  Under normal  circumstances,  the fund invests at
least 80% of its assets in:

- - Corporate debt securities: securities issued by domestic and foreign
  corporations;
- - U.S. government debt securities: securities issued or guaranteed by the U.S.
  government or its agencies or instrumentalities; and
- - 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:

- -   are looking for a more conservative option to a growth-oriented fund

- -   want a well-diversified and relatively stable investment allocation

- -   need a core investment

- -   seek a reasonable total return over the long term irrespective of its for
    (i.e., capital gains or ordinary income) or

- -   are retired or nearing retirement.

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

- -   are investing for maximum return over a long time horizon

- -   want your return to be either  ordinary  income or capital  gains,  but not
    both or

- -   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:

- -   are looking for a stock fund that has both growth and income components

- -   are looking for a more conservative option to a growth-oriented fund

- -   need a core investment

- -   seek above-average long-term total return through a combination of capital
    gains and ordinary income or

- -   are retired or nearing retirement.

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

- -   are investing for maximum return over a long time horizon

- -   desire your return to be either ordinary income or capital gains, but not
    both or

- -   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.

                         CAPITAL APPRECIATION STOCK FUND

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:

- -   have a longer investment time horizon

- -   are willing to accept higher on-going short-term risk for the potential of
    higher long-term returns

- -   want to diversify your investments

- -   are seeking a fund for the growth portion of an asset allocation program or

- -   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:

- -   are investing with a shorter investment time horizon in mind

- -   are seeking an  investment  based on income  rather than capital  gains or

- -   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.

How does the performance of the Capital  Appreciation  Stock Fund compare to the
capital appreciation market?

The following table compares the performance of the Capital  Appreciation  Stock
Fund with the performance of the Russell 3000 Index and S&P 1500  SuperComposite
Stock Index,  which are measures of the performance of the relevant market.  The
S&P 1500  SuperComposite  is a new  benchmark for the Fund. We intend to include
the S&P 1500  SuperComposite,  and not the S&P 400,  going  forward  because the
Adviser  believes  the S&P  1500  SuperComposit  more  accurately  reflects  the
securities held in the Fund's  portfolio of  investments.  Returns shown for the
Capital  Appreciation  Stock Fund are after the deduction of fund management and
operating expenses. The Russell 3000 Index, S&P 1500 SuperComposite, and S&P 400
Stock Index returns bear no such expenses.

                               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:

- -   have a longer investment time horizon

- -   are willing to accept higher on-going short-term risk for the potential of
    higher long-term returns

- -   want to diversify your investments

- -   are seeking a fund for the growth portion of an asset allocation program

- -   are seeking exposure to smaller companies as part of an asset allocation
    program or

- -   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:

- -   are investing with a shorter investment time horizon in mind

- -   are seeking an investment based on income rather than capital gain or

- -   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  includes  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  diversifies its holdings among various  industries and among companies
within those industries but is often 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 typically  invests 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  does not have a  calendar  year of  investment
performance,  so there is not a bar chart  showing the fund returns from year to
year.  Once the Fund has at least one calendar  year of  performance  it will be
shown  along with the  performance  of the S&P 400 Midcap  Index and the Russell
Midcap Index,  which we use to measure 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 ongoing  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 outside the U.S., 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:

- -   Fluctuations in currency exchange rates.
- -   Higher trading and custody charges compared to securities of U.S. companies.
- -   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.
- -   Less stringent securities regulations than those of the U.S.
- -   Potential political instability.
- -   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.  Class  C and  Class Z are  identical  except  that  Class  C  shares  bear a
distribution  fee pursuant to a distribution  plan,  adopted in accordance  with
Rule 12b-1 under the Act. Both Classes are sold in a continuous  offering.  This
prospectus offers the Class Z shares.

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 between May 1, 2000 and November 15, 2000, 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.


                                    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.

<PAGE>

                             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 regular trading on 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 $8 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 and may in the future manage
other funds 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.

CIMCO selects  subadvisers  based on a continuing  quantitative  and qualitative
evaluation of their skills and proven abilities in managing assets pursuant to a
particular  investment style.  While superior  performance is the ultimate goal,
short-term  performance by itself will not be a significant  factor in selecting
or  terminating  subadvisers,  and CIMCO  does not  expect  frequent  changes in
subadvisers.

CIMCO  received an order of the  Commission  that  permits the Ultra Series Fund
board to employ  particular  subadvisers  without  shareholder  approval for the
Mid-Cap Stock Fund. If there is a change in Mid-Cap Stock Fund subadvisers,  you
will  receive  an  "information  statement"  within 90 days of the  change.  The
statement  will provide you with relevant  information  about the reason for the
change and information about any new subadvisers.


CIMCO has engaged Wellington Management Company, llp ("Wellington  Management"),
75 State Street, Boston,  Massachusetts,  02109 as sub-adviser for the small-cap
portion of the assets within Mid-Cap Stock Fund.  Wellington  Management  became
the  sub-adviser on May 1, 2000.  Wellington  Management is a limited  liability
partnership  which traces its origins to 1928.  Wellington  Management  provides
investment services to investment companies, employee benefit plans, endowments,
foundations,  and other  institutions  and had over $235 billion in assets under
management as of December 31, 1999.

Stephen T. O'Brien,  CFA is the  Portfolio  Manager from  Wellington  Management
primarily  responsible for the Mid-Cap Stock Fund. Mr. O'Brien joined Wellington
Management in 1983 and has over 28 year of investment experience.


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.

For the Money  Market Fund,  the  "seven-day  average"  yield for the seven days
ended December 31, 1999, was 5.24% and the "effective" yield for that period was
5.38% (unaudited).

   *These  returns  are after all  charges at the  mutual  fund level have been
    subtracted.  These  returns  are higher  than the  returns  at the  separate
    account  level because  charges made at the separate  account level have not

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

<PAGE>

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  Adviseror  SubAdviser to be in good standing and will
not be made unless, in the judgment of the Investment Adviser or SubAdviser, 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.
<PAGE>

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.
<PAGE>

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.
<PAGE>

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.

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

involve  the  borrowing  of funds by a  customer  to finance  the  transactions.
Rather,  the initial margin is in the nature of a performance bond or good faith
deposit on the contract  which is returned to the Fund upon  termination  of the
futures  contract  assuming all  contractual  obligations  have been  satisfied.
Subsequent payments,  called
<PAGE>

"variation  margin," to or from the custodian,  will be made on a daily basis as
the price of the  underlying  stock index  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 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
<PAGE>

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
<PAGE>

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
<PAGE>

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.")
<PAGE>

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.
<PAGE>

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.
<PAGE>

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.
<PAGE>

                               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 high portfolio  turnover will be required in the stock
funds and stock  portion of the Balanced  Fund 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 in the stock funds 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).  In the Bond Fund and the bond portion of the Balanced  Fund,
management  employs  active  trading  techniques  which may result in  portfolio
turnover  rates of 500% or higher.  Such  active  trading  increased  the funds'
transaction  costs but is intended to more than  compensate  for such  increased
costs by capitalizing  on temporary  mispricing of securities in the bond market
due to  imbalances in supply and demand or changing  perceptions  of an issuer's
credit quality or prospects.

                             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.

Code of Ethics

The Ultra Series Fund, its adviser CIMCO,  Inc., and its principal  underwriter,
CUNA Brokerage  Services,  Inc.,  have adopted codes of ethics  pursuant to Rule
17j-1.  The codes  permit  access  people to  invest  in  securities,  including
securities  that may be purchased or held by the Fund,  for their own  accounts.
The codes, however, establish certain procedures and prohibitions on investments
in securities for personal accounts.  The codes are on public file with, and are
available from, the SEC.


                             THE INVESTMENT ADVISER

The Management  Agreement  ("Agreement")  requires that the  Investment  Adviser
provide continuous  professional investment management of the investments of the
Ultra Series Fund,  including  establishing an investment program complying with
the  investment  objectives,  policies  and  restrictions  of  each  Series.  In
addition,  the Adviser has agreed to provide,  or arrange to have provided,  all
services to each Series of the Ultra Series Fund,  including  but not limited to
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:

                        Management Fee Table

   Series                                    Management Fee

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

        1997     $5,320,543
        1998     $12,547,473
        1999     $17,105,630


The  Investment  Adviser or  subadviser  (as  applicable)  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 $1,268,229, $2,800,753 and $3,827,693 for those
services in 1997, 1998, and 1999, 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
$16,404, $0 and $0 for those services in 1997, 1998 and 1999, 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,  Wellington Management Company llp is the only
subadviser  managing  some of the assets of the Mid-Cap  Stock Fund.  Wellington
Management began managing
<PAGE>

these assets on May 1, 2000. The prospectus contains a description of Wellington
Management.  Wellington Management's services are paid for out of the management
fee CIMCO  receives  for the Mid-Cap  Stock  Fund.  There is no  additional  fee
charged to shareholders for Wellington Management's services.


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

        Janice C.  Doyle                Assistant Secretary
        Michael S.  Daubs               Director and President

                              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.
The Company absorbed $48,308,  $0 and $0 for the years ended December 31, 1997,
December 31, 1998, and December 31, 1999, respectively.


                         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
<PAGE>

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 1999 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
<PAGE>

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 ACCOUNTANTS

The financial  statements  for the fiscal year ended December 31, 1999 have been
included herein and elsewhere in the Registration Statement in reliance upon the
reports of PricewaterhouseCoopers  LLP, 100 East Wisconsin Avenue, Milwaukee, WI
53202, independent  accountants,  and upon the authority of said firm as experts
in accounting  and auditing.  The  financial  statements  for fiscal years ended
December 31, 1998 and prior have been audited by KPMG LLP.

                                    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
<PAGE>

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, 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. For
the year ended December 31, 1999, Capital Appreciation Stock Fund paid $563,777,
Growth and Income Stock Fund paid $497,353, Balanced Fund paid $131,328, and the
Mid-Cap Stock Fund paid $67,763 in brokerage fees.  There were no brokerage fees
paid by the Bond, Money Market or the Treasury 2000 Funds in 1999.

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.
<PAGE>

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
<PAGE>

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.
<PAGE>

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
<PAGE>

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 complet
             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
<PAGE>

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:
<PAGE>

(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
<PAGE>

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.
<PAGE>

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.
<PAGE>

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.
<PAGE>

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:
<PAGE>

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.
<PAGE>

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.

  ***If applicable, 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 had a coupon rate of 4.1% until October 1, 1994,
     at which time the stated coupon rate became 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 may be sold only to dealers in that
     program or other "qualified institutional  investors." On December 31,
     1999, the total market value of these investments was $15,329,376, or 6.12%
     of total net assets.

For the Money Market Fund, the "seven-day average" yield for the seven days
ended December 31, 1999, was 5.24% and the "effective" yield for that period
was 5.38%(unaudited).

    *These returns are after all charges at the mutual fund level have been
     subtracted. These returns are higher than the returns at the separate
     account level because charges made at the separate account level have not
     been subtracted.

   **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
     Expense Reimbursement Agreement between the Ultra Series Fund and CUNA
     Mutual Life Insurance Company.  If the Expense Reimbursement Agreement had
     not been in effect and if the full expenses allowable under the Investment
     Advisory Agreement between the Ultra Series Fund and the Investment Adviser
     had been charged, the resulting ratio of expenses to average net assets
     would have been 0.51%, 0.67% and 0.73% for 1997, 1996 and 1995,
     respectively.

     an Expense Reimbursement Agreement  between the Ultra Series Fund and CUNA
     Mutual Life Insurance  Company.  If the Expense Reimbursement Agreement had
     not been in effect and if the full expenses allowable under the Investment
     Advisory Agreement between the Ultra Series Fund and the Investment Adviser
     had been charged,  the resulting  ratio of expenses to average net assets
     would have been 0.83%, 0.66% and 0.75% for 1997, 1996 and 1995,
     respectively.

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 seven 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. The Mid-Cap Stock Fund commenced operations May 1, 1999. On or
     within 12 months prior to the portfolio  maturity  date,  the securities of
     the Treasury 2000 Fund will be liquidated.  Once the Treasury 2000 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.

     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, 1999, 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 and the Money Market Fund securities 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  daily
         based on the  valuation  of the net assets of the funds  divided by the
         number of  shares  of the fund  outstanding.  Expenses,  including  the
<PAGE>

         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 are declared and reinvested daily in
         additional  full  and  fractional  shares  of the  Money  Market  Fund.
         Dividends of net investment income from the Mid-Cap Stock Fund, Capital
         Appreciation  Stock Fund,  Growth and Income Stock Fund, Bond Fund, and
         Balanced Fund are declared and reinvested  quarterly in additional full
         and fractional  shares of the respective  funds.  Distributions  of 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.

         Generally  accepted   accounting   principals  require  that  permanent
         financial  reporting and tax differences be reclassified in the capital
         accounts.

         For federal  income tax  purposes,  at December 31, 1998,  the Balanced
         fund had a capital  loss  carryover  of  $2,476,442  that was offset by
         capital  gains in 1999.  At  December  31,  1999,  the Bond  Fund had a
         capital loss carryover of $7,838,884  that will expire in the year 2007
         if not offset by subsequent  capital gains. To the extent the Bond Fund
         realizes  future  net  capital  gains,  taxable  distributions  will be
         reduced by any unused capital loss carryover.

     (d) Security Transactions and Investment Income

         Security  transactions  are recorded on the trade date.  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) for each fund during the year
     ended December 31, 1999, were as follows:

(4)  Transactions with Affiliates

     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 fund at the following annual rates:

              Money Market                           0.45%
              Treasury 2000                          0.45%
              Bond                                   0.55%
              Balanced                               0.70%
              Growth and Income Stock                0.60%
              Capital Appreciation Stock             0.80%
              Mid-Cap Stock                          1.00%

     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.

     The  Investment  Advisor has entered  into a Subadvisor  Agreement  for the
     management of a portion of the  investments  in the Mid-Cap Stock Fund. The
     Investment Advisor is solely responsible for the payment of all fees to the
     Subadvisor. The Subadvisor for this Fund is Heartland Advisors, Inc.

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

     All capital shares  outstanding at December 31, 1999, are owned by separate
     investment accounts of CUNA Mutual Life.

     Certain  officers and trustees of the Fund are also officers of CUNA Mutual
     Life or CIMCO Inc.  During the year ended  December 31, 1999, the Fund made
     no direct payments to its officers and paid trustees' fees of approximately
     $15,830 to its unaffiliated trustees.

     Distribution Plan

     All shares are distributed  through CUNA Brokerage Service,  Inc. ("CBSI"),
     an affiliated  company,  or other registered  broker-dealers  authorized by
     CBSI. Class C Shares may also be subject to an asset-based distribution fee
     pursuant to Rule 12b-1 under the 1940 Act, equal to not more than 0.25%, on
     an annual  basis,  of the  average  value of the  daily net  assets of each
     series of the Fund attributable to Class C Shares on an annual basis.

ULTRA SERIES FUND

                        Report of Independent Accountants

To the Board of Trustees and Shareholders
Ultra Series Fund, Inc.

In our opinion, the accompanying statements of assets and liabilities, including
the schedules of  investments,  and the related  statements of operations and of
changes  in net assets  and the  financial  highlights  present  fairly,  in all
material  respects,  the financial  position of the Money Market Fund,  Treasury
2000 Fund,  Bond Fund,  Balanced  Fund,  Growth and Income  Stock Fund,  Capital
Appreciation  Stock Fund and Mid-Cap Stock Fund  (constituting  the Ultra Series
Fund,  Inc.,  hereafter  referred to as the "Fund") at December  31,  1999,  the
results of each of their operations, the changes in each of their net assets and
the  financial  highlights  for the  year  then  ended  (since  commencement  of
operations  May 1, 1999 for the Mid-Cap Stock Fund),  in  conformity  accounting
principles  generally accepted in the United States.  These financial statements
and financial highlights  (hereafter referred to as "financial  statements") are
the responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these financial  statements in accordance with auditing  standards  generally
accepted in the United States,  which require that we plan and perform the audit
to obtain reasonable  assurance about whether the financial  statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and  disclosures in the financial  statements,  assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall  financial  statement  presentation.  We believe that our
audit,  which  included  confirmation  of  securities  at  December  31, 1999 by
correspondence  with the custodian and brokers,  provides a reasonable basis for
the opinion  expressed above. The financial  statements of the Fund for the year
ended December 31, 1998, including the financial highlights for each of the four
years in the period then ended,  were audited by other  independent  accountants
whose report dated February 5, 1999  expressed an  unqualified  opinion on those
statements.

                          Independent Auditors' Report

The Board of Trustees and Shareholders
Ultra Series Fund:

We have  audited the  statements  of changes in net assets of Money Market Fund,
Treasury 2000 Fund, Bond Fund,  Balanced Fund, Growth and Income Stock Fund, and
Capital  Appreciation  Stock Fund (funds  within Ultra Series Fund) for the year
ended  December 31, 1998 and the financial  highlights  for each of the years in
the four-year period ended December 31, 1998. 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.  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.

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

                                   CIMCO Inc.
                                       and
                       Wellington Management Company, llp

         THIS INVESTMENT SUB-ADVISORY AGREEMENT  ("Agreement"),  effective as of
the  1st day of May, 2000, by  and  between  CIMCO  Inc., an  Iowa  corporation
(the "Adviser"), and Wellington Management Company, llp, a Massachusetts limited
liability partnership (the "Sub-Adviser").

         Adviser and Sub-Adviser agree as follows:

1.  Adviser  hereby  engages the  services of  Sub-Adviser  in  connection  with
Adviser's  management  of a portion of the assets (which could be up to 100%) of
the Mid-Cap Stock Fund (the  "Portfolio") of the Ultra Series Fund (the "Fund").
Adviser  intends to use a manager of managers  approach to the management of the
Portfolio,  as well as other  portfolios in the Fund.  Therefore,  the number of
sub-advisers  and the  percentage  of assets of the  Portfolio  managed  by each
sub-adviser  will be  determined  by the Fund's Board of Trustees and CIMCO from
time to time.  The  portion of the assets  assigned to the  Sub-Adviser  will be
referred to as the Sub-Portfolio.  Pursuant to this Agreement and subject to the
oversight and  supervision by Adviser and the officers and the Board of Trustees
of the Fund,  Sub-Adviser  shall manage the investment and  reinvestment  of the
assets of the Sub-Portfolio as requested by CIMCO.

2. Sub-Adviser  hereby accepts  employment by Adviser in the foregoing  capacity
and agrees,  at its own expense,  to render the services set forth herein and to
provide the office space, furnishings, equipment and personnel required by it to
perform  such  services on the terms and for the  compensation  provided in this
Agreement.

3. In particular,  Sub-Adviser shall furnish  continuously an investment program
for the  Sub-Portfolio  and shall  determine from time to time in its discretion
the  securities  and other  investments to be purchased or sold or exchanged and
what portions of the Sub-Portfolio shall be held in various securities,  cash or
other investments. In this connection, Sub-Adviser shall provide Adviser and the
officers  and Trustees of the Fund with such  reports and  documentation  as the
latter  shall  reasonably  request  regarding  Sub-Adviser's  management  of the
Sub-Portfolio's assets.

4.  Sub-Adviser  shall carry out its  responsibilities  under this  Agreement in
compliance  with:  (a)  the  Portfolio's  investment  objective,   policies  and
restrictions as set forth in the Fund's current registration statement, (b) such
policies or directives as the Fund's Trustees may from time to time establish or
issue,  and (c) applicable law and related  regulations.  Adviser shall promptly
<PAGE>

notify  Sub-Adviser of changes to (a) or (b) above and shall notify  Sub-Adviser
of changes to (c) above promptly after it becomes aware of such changes.

5. The  Sub-Adviser  and Adviser  acknowledge  that the  Sub-Adviser  is not the
compliance  agent for the Fund or for the  Adviser,  and does not have access to
all of the Fund's or the  Portfolio's  books and  records  necessary  to perform
certain  compliance  testing.  To the extent that the  Sub-Adviser has agreed to
perform the services  specified in this Agreement in accordance  with the Fund's
registration  statement,  the  Fund's  Declaration  of  Trust,  the  Portfolio's
prospectus and any policies  adopted by the Fund's Board of Trustees  applicable
to the Portfolio,  and in accordance with applicable law, the Sub-Adviser  shall
perform  such  services  based upon its books and  records  with  respect to the
Portfolio,  which comprise a portion the Portfolio's books and records, and upon
information and written instructions  received from the Fund or the Adviser, and
shall not be held  responsible  under this Agreement so long as it performs such
services in accordance with this Agreement,  the policies of the Fund's Board of
Trustees  and  applicable  law  based  upon  such  books  and  records  and such
information and  instructions  provided by the Fund or the Adviser.  The Adviser
shall promptly  provide the Sub-Adviser  with copies of the Fund's  registration
statement,  the Fund's Declaration of Trust, the Portfolio's currently effective
prospectus and any written policies or procedures adopted by the Fund's Board of
Trustees applicable to the Portfolio and any amendments or revisions thereto.

6.  The  Sub-Adviser  shall  have  full and  complete  discretion  to  establish
brokerage  accounts  with  one or  more  brokers,  dealers  or  other  financial
intermediaries  as Sub-Adviser  may select,  including  those which from time to
time may furnish to  Sub-Adviser or its  affiliates  statistical  and investment
research  information and other services.  Sub-Adviser will place orders with or
through such brokers,  dealers or other financial  intermediaries  in accordance
with Wellington  Management's Statement of Policy on Brokerage Practices and the
policy with respect to brokerage set forth in the Fund's Registration  Statement
or as the Board of Trustees  or the  Adviser  may direct  from time to time,  in
conformity with federal securities laws

    On occasions when Sub-Adviser  deems the purchase or sale of a security to
be in the best interest of the  Sub-Portfolio as well as other clients of the
Sub-Adviser,  the  Sub-Adviser  to the extent  permitted by applicable  laws and
regulations,  may, but shall be under no obligation to, aggregate the securities
to be  purchased  or sold to attempt to obtain a more  favorable  price or lower
brokerage commissions and efficient execution.  In such event, allocation of the
securities  so  purchased  or  sold,  as well as the  expenses  incurred  in the
transactions,  will be made by the  Sub-Adviser  in the manner  the  Sub-Adviser
considers to be the most equitable and consistent with its fiduciary obligations
to the Portfolio and to its other clients.

7.  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 Portfolio may be invested.
<PAGE>

    The Sub-Adviser shall not file class action claims or derivative shareholder
claims on behalf of the Sub-Advised Funds. However, the Sub-Adviser will provide
transaction information to the Client or custodian upon reasonable request.

8.  Sub-Adviser's  services under this Agreement are not exclusive.  Sub-Adviser
may provide the same or similar services to other clients. Sub-Adviser shall for
all purposes herein be deemed to be an independent  contractor and shall, unless
otherwise  expressly  provided or  authorized,  have no  authority to act for or
represent  the Adviser,  the Fund or the Portfolio or otherwise be deemed agents
of the Adviser, the Fund or the Portfolio.

9.  For the services rendered, the facilities furnished and the expenses assumed
by  Sub-Adviser,  Adviser shall pay  Sub-Adviser at the end of each month, a fee
based on the average daily net assets of each Portfolio at the following  annual
rates:

    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  in the  manner and on the dates set
forth in the  current  prospectus  of the  Fund,  and,  on days on which the net
assets are not so determined,  the net asset value  computation to be used shall
be as  determined  on the next day on  which  the net  assets  shall  have  been
determined.  In the event of termination of this Agreement, all compensation due
through the date of termination  will be calculated on a pro-rated basis through
the date of  termination  and paid within  thirty  business  days of the date of
termination.

    During  any  period  when  the  determination  of net  asset  value  is
suspended,  the net asset value of the Sub-Portfolio as of the last business day
prior to such  suspension  shall for this  purpose be deemed to be the net asset
value at the close of each succeeding business day until it is again determined.

10. The  Sub-Adviser  shall  maintain  all books and records with respect to the
Sub-Advised Fund's portfolio transactions required by subparagraphs (b)(5), (6),
(7), (9),  (10) and (11) and  paragraph  (f) of Rule 31a-1 under the  Investment
company Act of 1940,  as amended  (the "1940  Sub-Act")  and shall render to the
Manager such periodic and special reports as the Manager may reasonably request.

    Sub-Adviser  agrees  that all  books  and records which it maintains for the
Sub-Portfolio  or the Fund pursuant to this section are the property of the Fund
and  further  agrees to  surrender  promptly to the Adviser or the Fund any such
books, records or information upon the Adviser's or the Fund's request. All such
books and  records  shall be made  available,  within  five  business  days of a
written request,  to the Fund's  accountants or auditors during regular business
hours  at  Sub-Adviser's  offices.  Adviser  and the  Fund or  either  of  their
authorized  representative  shall  have the  right to copy  any  records  in the
possession  of  Sub-Adviser  which  pertain to the  Portfolio or the Fund.  Such
books,  records,  information  or reports  shall be made  available  to properly
authorized  government  representatives  consistent  with state and  federal law
and/or regulations.  In the event of the termination of this Agreement, all such
books,  records or other  information  shall be  returned to Adviser or the Fund
free from any claim or assertion of rights by Sub-Adviser.
<PAGE>

11. 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 Portfolio,  the Adviser and the Sub-Adviser
in connection with the services provided  pursuant to this Agreement;  provided,
however,  that this  agreement to cooperate  does not apply to the  provision of
information,  reports  and other  materials  which  either  the  Adviser  or the
Sub-Adviser  reasonably  believes the regulatory or administrative body does not
have the authority to request or is the privileged or  confidential  information
of the Adviser or Sub-Adviser.

12. Each party to this  agreement  agrees  that it will not  disclose or use any
records or information of the other party (the "non-disclosing  party") obtained
pursuant to this Agreement in any manner whatsoever except as authorized in this
Agreement and that it will keep confidential any non-public information obtained
pursuant to this Agreement and disclose such information only if  non-disclosing
party (or the Fund, in cases where the non-disclosing  party is the Adviser) has
authorized  such  disclosure,  or if such  disclosure  is required by federal or
state regulatory authorities.

13. In the absence of willful misfeasance,  bad faith or gross negligence on the
part  of  Sub-Adviser  or its  officers,  Trustees  or  employees,  or  reckless
disregard by Sub-Adviser of its duties under this Agreement,  Sub-Adviser  shall
not be liable to Adviser,  the Portfolio,  the Fund or to any shareholder of the
Portfolio for any act or omission in the course of, or connected with, rendering
services  hereunder  or for any losses that may be  sustained  in the  purchase,
holding or sale of any security, except to the extent specified in Section 36(b)
of the 1940 Act  concerning  loss resulting from a breach of fiduciary duty with
respect to the receipt of compensation for services.

                                Ultra Series Fund
                                 Code of Ethics
                    Amended and Restated as of March 19, 1997

Introductory Statement

On January 21, 1987, the Board of Trustees of the Ultra Series Fund (the "Fund")
adopted a Code of Ethics (the "Code"). The goal of this Code is to safeguard the
interests of the Fund shareholders, without incurring unnecessary administrative
duplication of existing procedures.  Therefore,  this Code incorporates sections
4.l, 4.2, and 5.4 of the Policy Against Insider Trading (Policy) adopted October
14, 1994, as amended March 19, 1997, by the Board of the  Investment  Adviser to
the Fund, CIMCO Inc. (CIMCO).

Statement of General Principles

All  persons  associated  with  the  Fund  shall  place  the  interests  of  the
shareholders  of the Fund before  their own  personal  interests.  All  personal
securities  transactions  shall be  conducted  in such a manner  as to avoid any
actual or potential  conflict of interest or any abuse of any person's  position
of trust and  responsibility  to the Fund.  No person  associated  with the Fund
shall take inappropriate advantage of the person's association with the Fund.

Quarterly reports of personal securities transactions shall be completed by each
person  subject to section 17(j) of the Investment  Company Act, for example,  a
person who:

         "makes any  recommendation,  participates in the determination of which
         recommendation  shall be made,  or whose  principal  function or duties
         relate to the  determination of which  recommendation  shall be made to
         any  registered  investment  company;  or who, in  connection  with his
         duties, obtains any information  concerning securities  recommendations
         being  made by such  investment  adviser to any  registered  investment
         company."

Certification of Compliance

Each person who completes a quarterly report of personal securities transactions
shall certify annually that:

         - The person has read and understood  this Code and recognizes that the
person is subject to it.

         - The person has complied with the requirements of this Code and has
reported all personal securities  transactions required to be reported.

Prohibitions

No person who completes a quarterly report of personal  securities  transactions
may:

         -  Acquire any securities of an initial  public  offering for the
            person's own account until the seventh  calendar day after the
            offering date and then only at the prevailing market price for
            bonafide long-term  investment in accordance with the person's
            normal investment practice.

         -  Acquire any  securities  through a private  placement  for the
            person's own account without the prior written approval of the
            majority of the noninterested trustees of the Fund.

         -  Accept any gift or other  thing of more than de minimus  value
            from any person or entity that does business with or on behalf
            of the Fund.

         -  Serve as a director of a publicly  traded company  without the
            prior  written  approval of the majority of the  noninterested
            trustees of the Fund.

Restricted List

This Code incorporates the provisions of the CIMCO Policy reproduced below:

         "4.1     The  Restricted  List  is  the   responsibility  of  the  Vice
                  President-Investments.  The Restricted  List shall include two
                  categories  of  securities.  The first  category  includes any
                  equity security which CIMCO, on behalf of clients,  intends to
                  trade or is trading. The second category includes any security
                  of any  company  moved from the Watch  List to the  Restricted
                  List.  CIMCO is prohibited from trading in any security in the
                  second
<PAGE>

                  category. The list will be kept in a nonpublic place in
                  the   custody   of   a   person   designated   by   the   Vice
                  President-Investments. The Restricted List will show:

                  -        the date and time the security was added to the list,

                  -        the name of the person who added it,

                  -        the date and time a security was deleted,

                  -        the name of the person who deleted it,

                  -        whether the  security is in  category  one,  that is,
                           CIMCO is trading or intending to trade the  security,
                           or is in category  two,  that is, CIMCO is prohibited
                           from trading the security.

         4.2      Do not make any trade or recommendation involving any security
                  or any  option  on a  security  on  the  Restricted  List  for
                  yourself,  any  member of your  family,  or any other  person,
                  except  that you may  trade  securities  in  category  one for
                  clients of CIMCO.  Personal  trading is prohibited  during the
                  entire time a security is on the Restricted List and for seven
                  calendar  days after the  security  has been  removed from the
                  Restricted List. In addition,  the quarterly audit will review
                  personal  trading within seven days before a security is added
                  to the Restricted  List. The Compliance  Committee [as defined
                  in the CIMCO  Policy]  shall  determine  whether any abuse has
                  occurred. If an abuse has occurred,  any profit resulting from
                  the abuse shall be disgorged and any other appropriate  action
                  taken. To facilitate  review of personal trades,  any of which
                  may  prove  to have  been  made  within  seven  days  before a
                  security is added to the  Restricted  List, all personnel with
                  authority  to make  trading  decisions  on behalf of CIMCO and
                  clients  of CIMCO  shall  document  in  writing  all  personal
                  trades,  at the time of the  trade,  indicating  why the trade
                  would  not be  appropriate  for  CIMCO  and its  clients.  The
                  written  documentation  shall be filed  within 24 hours  after
                  making the trade in the Restricted List File."

Quarterly Audits

This Code incorporates the provisions of the CIMCO Policy reproduced below:

     "5.4 A person  designated by the head of Internal Auditing shall conduct an
          audit   within  the  month   following   the  end  of  each   quarter.
          Notwithstanding  the provisions of section 3.2, the names of companies
          on the Watch List shall be made  available to the auditor for purposes
          of the quarterly  audit.  The audit will review  quarterly  reports of
          personal  securities  transactions  and compare personal trades to the
          Restricted List. Any personal trades involving  securities  restricted
          at the time of the trade or within the seven  calendar days  preceding
          the date a security  was added to the  Restricted  List will be noted.
          The audit will also review  whether  securities  of  companies  on the
          Watch List were traded  during the  quarter.  The results of the audit
          will be presented to the members of the Compliance Committee."

Board Review

As soon as necessary, but in no event later than the board meeting following the
second quarter of 2000, the Board shall review any  difficulties  encountered in
administering  this Code, any material  violations of this Code, and any changes
in applicable laws and regulations.  At the time of such review, the Board shall
consider the interests of shareholders  and shall make any changes  necessary to
comply with statutory and regulatory changes.

Sanctions

Violation of this Code may subject any person who completes quarterly reports to
disciplinary action. The Compliance Committee will report material violations to
the Board of Trustees and to regulatory authorities.

III. Miscellaneous.

     A.   Restricted List.

          A designated  CIMCO  employee will maintain the  restricted  list. The
          restricted  list will include all stocks for which CIMCO has a pending
          buy or sell order (excepted as described  below).  A stock will remain
          on the  restricted  list for seven  calendar  days  after the trade is
          executed or withdrawn. Anyone who purchases a stock while it is on the
          restricted  list will be directed to sell the stock and  disgorge  any
          profits to the United Way of Dane County. Additionally,  all portfolio
          managers are prohibited  from buying or selling stock within seven (7)
          days before a portfolio he/she manages trades in that stock. Issues of
          stocks with a market  capitalization of more than $50 billion will not
          be included on the restricted list.  However, if there is any question
          as to an issuer's  market  capitalization  exceeding $50 billion,  the
          designated employee is directed to include it on the list.

     B.   Private Placement Information.

          A watch list will be maintained by a designated  CIMCO  employee.  The
          Watch List will  include  companies  for which the  private  placement
          section has current material, nonpublic information. A company will be
          removed from the Watch List when the  designated  employee  determines
          the  information is no longer  material,  nonpublic  information.  The
          designated  employee  will also maintain a locked file system to house
          the material,  nonpublic  information.  The  designated  employee will

                          CUNA BROKERAGE SERVICES, INC.
                                 Code of Ethics
                            Adopted September 1, 1997

Introductory Statement
CUNA  Brokerage is adopting  this Code of Ethics to safeguard  the  interests of
CUNA  Brokerage's  customers,   without  incurring  unnecessary   administrative
duplication of existing procedures.

CUNA  Brokerage  is an  affiliated  company of CIMCO,  a  registered  investment
advisor.  CIMCO is sponsoring an Investment  Company for which CUNA Brokerage is
acting as principal  underwriter.  This Code of Ethics is adopted to address the
requirements  of Section 17(j) of the  Investment  Company Act of 1940, and Rule
17j-1 promulgated in accordance with the Investment Company Act.

Statement of General Policy
All  persons  associated  with  CUNA  Brokerage  shall  place the  interests  of
customers  before  their  own  personal   interests.   All  personal  securities
transactions  shall be  conducted  in such a manner  as to avoid  any  actual or
potential  conflict of interest or any abuse of any  person's  position of trust
and responsibility to CBS or its affiliated organizations.  No person associated
with CBS shall take  inappropriate  advantage of the person's  association  with
CBS.

Quarterly reports of personal securities transactions shall be completed by each
person  subject to section 17(j) of the Investment  Company Act, for example,  a
person who:

     "makes  any  recommendation,  participates  in the  determination  of which
     recommendation  shall be made, or whose principal function or duties relate
     to  the  determination  of  which  recommendation  shall  be  made  to  any
     registered  investment  company;  or who,  in  connection  with his duties,
     obtains any information concerning securities recommendations being made by
     such investment adviser to any registered investment company."

Certification of Compliance

Each person who completes a quarterly report of personal securities transactions
shall certify annually that:

     -    The person has read and understands  this Code and recognizes that the
          person is subject to it.

     -    The person has  complied  with the  requirements  of this Code and has
          reported all personal securities transactions required to be reported.

Prohibitions
No person who completes a quarterly report of personal  securities  transactions
may:

     -    Acquire any securities of an initial public  offering for the person's
          own account until the seventh calendar day after the offering date and
          then  only at the  prevailing  market  price  for  bonafide  long-term
          investment in accordance with the person's normal investment practice.

     -    Acquire any  securities  through a private  placement for the person's
          own account without the prior written approval of CBS.

     -    Accept any gift or other thing of more than de minimus  value from any
          person or entity that does business with or on behalf of CBS.

     -    Serve as a director  of a publicly  traded  company  without the prior
          written approval of CBS.

Restricted List
This Code incorporates the provisions of the CIMCO Policy reproduced below:

     "4.1 The  Restricted  List  is  the   responsibility  of  the  Senior  Vice
          President.  The  Restricted  List  shall  include  two  categories  of
          securities.  The first  category  includes any equity  security  which
          CIMCO,  on behalf of  clients,  intends  to trade or is  trading.  The
          second  category  includes any security of any company  moved from the
          Watch List [as defined in the CIMCO  policy] to the  Restricted  List.
          CIMCO  is  prohibited  from  trading  in
<PAGE>

          any  security  in the  second  category.  The  list  will be kept in a
          nonpublic  place in the custody of a person  designated  by the Senior
          Vice President. The Restricted List will show:

          -    the date and time the security was added to the list,

          -    the name of the person who added it,

          -    the date and time a security was deleted,

          -    the name of the person who deleted it,

          -    whether  the  security  is in  category  one,  that is,  CIMCO is
               trading or  intending  to trade the  security,  or is in category
               two, that is, CIMCO is prohibited from trading the security.

     4.2  Do not make any trade or recommendation  involving any security or any
          option on a security on the Restricted  List for yourself,  any member
          of your  family,  or any  other  person,  except  that  you may  trade
          securities  in  category  one [as  defined  in hte CIMCO  policy]  for
          clients of CIMCO.  Personal  trading is  prohibited  during the entire
          time a security is on the Restricted  List and for seven calendar days
          after the  security  has been removed  from the  Restricted  List.  In
          addition,  the quarterly  audit will review  personal  trading  within
          seven days  before a security  is added to the  Restricted  List.  The
          Compliance  Committee [as defined in the CIMCO Policy] shall determine
          whether any abuse has occurred.  If an abuse has occurred,  any profit
          resulting from the abuse shall be disgorged and any other  appropriate
          action taken. To facilitate  review of personal  trades,  any of which
          may prove to have been made  within  seven days  before a security  is
          added to the  Restricted  List,  all personnel  with authority to make
          trading  decisions  on  behalf  of CIMCO and  clients  of CIMCO  shall
          document in writing  all  personal  trades,  at the time of the trade,
          indicating  why the trade would not be  appropriate  for CIMCO and its
          clients.  The  written  documentation  shall be filed  within 24 hours
          after making the trade in the Restricted List File."

Quarterly Audits
This Code incorporates the provisions of the CIMCO Policy reproduced below:

     "5.4 A person  designated by the head of Internal Auditing shall conduct an
          audit   within  the  month   following   the  end  of  each   quarter.
          Notwithstanding  the provisions of section 3.2, the names of companies
          on the Watch List shall be made  available to the auditor for purposes
          of the quarterly  audit.  The audit will review  quarterly  reports of
          personal  securities  transactions  and compare personal trades to the
          Restricted List. Any personal trades involving  securities  restricted
          at the time of the trade or within the seven  calendar days  preceding
          the date a security  was added to the  Restricted  List will be noted.
          The audit will also review  whether  securities  of  companies  on the
          Watch List were traded  during the  quarter.  The results of the audit
          will be presented to the members of the Compliance Committee."

Board Review
The Board shall review any difficulties  encountered in administering this Code,
any material  violations of this Code,  and any changes in  applicable  laws and
regulations.  At the time of such review, the Board shall consider the interests
of customers and shall make any changes  necessary to comply with  statutory and
regulatory changes.

Exceptions
All Directors,  Officers and Advisory Persons, as defined in Rule 17j-1, who are
subject to a similar Code of Ethics and reporting requirement,  are not required
to make quarterly reports to CUNA Brokerage. This exception specifically applies
to Directors,  Officers and Advisory Persons of CUNA Brokerage  Services subject
to the Code of Ethics adopted by CIMCO and/or Ultra Series Fund.

Sanctions
Violation of this Code may subject any person who completes quarterly reports to
disciplinary  action. The Compliance Officer will report material  violations to
the Board and to regulatory authorities.
