                          ABOUT THE SERIES OF THE TRUST

JNL/Alger Growth Series

Investment Objective. The investment objective of the JNL/Alger Growth Series is
long-term capital appreciation.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing at least 65% in a diversified  portfolio of equity securities - common
stock,  preferred  stock,  and securities  convertible  into or exchangeable for
common stock - of large,  companies which trade on U.S. exchanges or in the U.S.
over-the-counter market. The Series considers a large company to be one that, at
the time its securities are acquired by the Series, has a market  capitalization
of $1 billion or more.  These  companies  typically  have broad  product  lines,
markets, financial resources and depth of management.

To provide flexibility to take advantage of investment opportunities, the Series
may hold a portion  of its assets in money  market  investments  and  repurchase
agreements.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

o        Market  risk.   Because  the  Series  invests  in  U.S.  traded  equity
         securities,  it is subject to stock market risk. Stock prices typically
         fluctuate more than the values of other types of securities,  typically
         in response to changes in the particular  company's financial condition
         and factors affecting the market in general.  For example,  unfavorable
         or unanticipated poor earnings performance of the company may result in
         a decline in its stock's price, and a broad-based  market drop may also
         cause a stock's price to fall.

o        Growth investing risk.  Growth companies  usually invest a high portion
         of earnings in their  businesses,  and may lack the  dividends of value
         stocks  that can cushion  prices in a falling  market.  Also,  earnings
         disappointments   often  lead  to  sharp  declines  in  prices  because
         investors  buy  growth  stocks in  anticipation  of  superior  earnings
         growth.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series. The Series may take a temporary,  defensive position by
investing  up to all of its  assets  in  debt  securities  (typically  of a high
grade), cash equivalents and repurchase agreements.  Taking a defensive position
may reduce the potential for appreciation in the Series' portfolio.

The Series may actively  trade  securities in seeking to achieve its  objective.
Doing so may increase transaction costs, which may reduce performance.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

Sub-Adviser and Portfolio  Management.  The sub-adviser to the JNL/Alger  Growth
Series is Fred Alger Management, Inc. (Alger Management),  which is located at 1

generally engaged in the business of rendering  investment  advisory services to
institutions and, to a lesser extent,  individuals and has been so engaged since

employed  by Alger  Management  as  Executive  Vice  President  and  Director of
Research since 1971, and as President since 1995. He serves as portfolio manager
for other  mutual funds and  investment  accounts  managed by Alger  Management.

JNL/Alliance Growth Series

Investment Objective. The investment objective of the JNL/Alliance Growth Series
is long-term growth of capital.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  primarily in a  diversified  portfolio of common stocks or securities
with  common  stock  characteristics  that  the  sub-adviser  believes  have the
potential for capital  appreciation.,  which include securities convertible into
or  exchangeable  for  common  stock.  In  selecting  equity   securities,   the
sub-adviser  considers  a variety of factors,  such as an  issuer's  current and
projected  revenue,  earnings,  cash flow and assets,  as well as general market
conditions.  Because the Series holds  securities  selected for growth potential
rather than protection of income, the value of the Series' portfolio may be more
volatile  in  response  to market  changes  than it would be if the Series  held
income-producing securities.

The Series invests primarily in high-quality U.S. companies,  generally those of
large  market  capitalization.  The Series may invest a portion of its assets in
foreign  securities.  The potential for appreciation of capital is the basis for
investment  decisions.  Whatever  income the  Series'  investments  generate  is
incidental to the objective of capital growth.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

o        Market risk.  Because the Series  invests in stocks of U.S. and foreign
         companies,  it is subject to stock market risk.  Stock prices typically
         fluctuate more than the values of other types of securities,  typically
         in response to changes in the particular  company's financial condition
         and factors affecting the market in general.  For example,  unfavorable
         or unanticipated poor earnings performance of the company may result in
         a decline in its stock's price, and a broad-based  market drop may also
         cause a stock's price to fall.

o        Growth investing risk.  Growth companies  usually invest a high portion
         of earnings in their  businesses,  and may lack the  dividends of value
         stocks  that can cushion  prices in a falling  market.  Also,  earnings
         disappointments   often  lead  to  sharp  declines  in  prices  because
         investors  buy  growth  stocks in  anticipation  of  superior  earnings
         growth.

o        Foreign investing risk.  Foreign investing involves risks not typically
         associated  with U.S.  investment.  These risks include,  among others,
         adverse  fluctuations  in  foreign  currency  values as well as adverse
         political,   social  and  economic  developments  affecting  a  foreign
         country.   In  addition,   foreign  investing  involves  less  publicly
         available  information  and more  volatile  or less  liquid  securities
         markets.  Investments in foreign countries could be affected by factors
         not  present  in the  U.S.,  such  as  restrictions  on  receiving  the
         investment  proceeds  from a foreign  country,  foreign  tax laws,  and
         potential   difficulties   in   enforcing   contractual    obligations.
         Transactions  in foreign  securities  may be subject to less  efficient
         settlement  practices,  including  extended  clearance  and  settlement
         periods.  Foreign  accounting  may  be  less  revealing  than  American
         accounting   practices.   Foreign   regulation  may  be  inadequate  or
         irregular.   Owning   foreign   securities   could  cause  the  Series'
         performance to fluctuate more than if it held only U.S. securities.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the  Series.  The Series may use  derivative  instruments,  such as
futures contracts,  options and forward currency contracts, for hedging and risk
management.  These  instruments  are  subject to  transaction  costs and certain
risks,  such as unanticipated  changes in securities  prices and global currency
markets.

The Series may take a temporary,  defensive  position by investing a substantial
portion of its assets in U.S. government securities,  cash, cash equivalents and
repurchase agreements.  Taking a defensive position may reduce the potential for
appreciation in the Series' portfolio.  The Series may actively trade securities
in seeking to achieve its objective.  Doing so may increase  transaction  costs,
which may reduce performance.
The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

JNL/Eagle Core Equity Series

Investment  Objective.  The  investment  objective of the JNL/Eagle  Core Equity
Series is long-term capital appreciation and, secondarily, current income.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  at least 65% of total  assets in a  diversified  portfolio  of common
stock of U.S.  companies that meet the criteria for one of three separate equity
strategies: the growth equity strategy, the value equity strategy and the equity
income strategy.

o        Under the growth equity strategy, the sub-adviser selects common stocks
         in part  based on its  opinions  regarding  the  sustainability  of the
         company's  competitive  advantage in the  marketplace and the company's
         management  team.  The  sub-adviser  looks for  securities of companies
         which have an exceptional  management team and which have the potential
         to increase  market  share and drive  earnings per share  growth.  If a
         particular  stock  appreciates  to over 5% of the  total  assets of the
         portfolio,  the sub-adviser  typically will reduce the position to less
         than 5%.  Generally,  the  sub-adviser  will  sell a stock if its price
         appreciates to a level that the sub-adviser views as not sustainable or
         to  purchase  stock  that the  sub-adviser  believes  presents a better
         investment opportunity.

                  The sub-adviser seeks securities of companies which:

                  --       have projected  earnings  growth and return on equity
                           greater than 15%,

                  --       are dominant in their industries, and

                  --       have the ability to create and sustain a  competitive
                           advantage.

o        Under the value equity strategy,  the sub-adviser invests in securities
         which it believes indicate  above-average  financial soundness and high
         intrinsic value relative to price.  The sub-adviser  screens a universe
         of over 2,500  companies.  From this universe,  the  sub-adviser  makes
         selections based on its projections of the company's growth in earnings
         and  dividends,  earnings  momentum,  and  undervaluation  based  on  a
         dividend  discount model.  The  sub-adviser  develops target prices and
         value ranges from this  analysis  and makes  portfolio  selection  from
         among the top-rated  securities.  The sub-adviser will typically sell a
         security if the security  reaches its target  price,  negative  changes
         occur  with  respect  to the  issuer  or its  industry,  or  there is a
         significant  change  in  one  or  more  of  the  four   characteristics
         applicable  to  the  security's  selection.  However,  the  Series  may
         continue to hold equity  securities  that no longer meet the  selection
         criteria but that the sub-adviser deems suitable investments in view of
         the Series' investment objective.

                  These securities or their respective issuers have at least one
                  of the following characteristics when acquired for the Series:

                  --       low  price-to-earnings  price-to-book value, price to
                           cash flow and  price-to-sales  ratios, as compared to
                           the broad  market,  industry  peers and the company's
                           historical ratios
                  --       above average dividend yield , or
                  --       Beta below that of the broad market

o        Under  the  equity  income   strategy,   the  sub-adviser   invests  in
         income-producing securities.

The sub-adviser divides the Series' assets among each of these three strategies,
with about 40% of the assets  allocated  to each of the growth  equity and value
equity strategies and about 20% to the equity income strategy.

Under normal market conditions, the Series invests at least 65% of its assets in
the  common  stock  of U.S.  companies  and may  invest  the  balance  in  other
securities, such as common stock of foreign issuers, corporate debt obligations,
U.S. Government  securities,  preferred stock,  convertible stock,  warrants and
rights to buy common stock, real estate investment trusts, repurchase agreements
and  money  market   instruments.   Investing  in  foreign  securities  presents
additional  risks,  such as those related to currency  fluctuations  and adverse
political  or economic  conditions  affecting a foreign  country.  Although  the
Series emphasizes  investment-grade  securities (or unrated  securities that the
sub-adviser  deems to be of  comparable  quality),  the  Series  may  invest  in
non-investment-grade  securities.  A non-investment grade security may fluctuate
more in value,  and  present  a greater  risk of  default,  than a  higher-rated
security.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk. Because the Series invests primarily in stocks of
                  U.S.  companies,  it is subject to stock  market  risk.  Stock
                  prices typically fluctuate more than the values of other types
                  of  securities,  typically  in  response  to  changes  in  the
                  particular company's financial condition and factors affecting
                  the  market  in   general.   For   example,   unfavorable   or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

         o        Growth investing risk.  Growth companies usually invest a high
                  portion  of  earnings  in their  businesses,  and may lack the
                  dividends of value stocks that can cushion prices in a falling
                  market.  Also,  earnings  disappointments  often lead to sharp
                  declines  in prices  because  investors  buy growth  stocks in
                  anticipation of superior earnings growth.

         o        Derivatives risk. Investing in derivative instruments, such as
                  options,   futures  contracts,   forward  currency  contracts,
                  indexed  securities  and  asset-backed  securities,   involves
                  special risks. The Series' sub-advisers must correctly predict
                  the price movements,  during the life of a derivative,  of the
                  underlying  asset in order to realize the desired results from
                  the investment. The value of derivatives may rise or fall more
                  rapidly  than  other  investments,   which  may  increase  the
                  volatility of the Series depending on the nature and extent of
                  the derivatives in the Series'  portfolio.  If the sub-adviser
                  uses  derivatives  in  attempting  to  manage or  "hedge"  the
                  overall  risk of the  portfolio,  the  strategy  might  not be
                  successful,  for  example,  due to changes in the value of the
                  derivatives  that do not correlate with price movements in the
                  rest of the portfolio.

         o        Value investing risk. The value approach carries the risk that
                  the market will not recognize a security's intrinsic value for
                  a long  time,  or that a stock  judged to be  undervalued  may
                  actually be appropriately priced.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

The  Series  may also  use  derivative  instruments,  such as  options,  futures
contracts and indexed  securities,  which are subject to  transaction  costs and
certain risks, such as unanticipated changes in securities prices.

For temporary defensive purposes during actual or anticipated periods of general
market  decline,  the Series  may invest up to 100% of its assets in  high-grade
money market instruments,  including U.S. Government securities,  and repurchase
agreements  secured  by such  instruments,  as well as other  high-quality  debt
securities.   Taking  a  defensive   position  may  reduce  the   potential  for
appreciation in the Series' portfolio.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

JNL/Eagle SmallCap Equity Series

Investment Objective.  The investment objective of the JNL/Eagle SmallCap Equity
Series is long-term capital appreciation.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  65%  of  its  total  assets  in a  diversified  portfolio  of  equity
securities of domestic small capitalization companies, i.e., companies which, at
the time of purchase,  typically have a market  capitalization under $1 billion.
The  sub-adviser  employs a  bottom-up  approach to  identify  rapidly  growing,
under-researched small capitalization companies that appear to be undervalued in
relation to their long term earnings growth rate or asset value. The sub-adviser
generally  invests in companies  which have  accelerating  earnings,  reasonable
valuations  strong management that participates in the ownership of the company,
reasonable  debt, and a high or expanding  return on equity.  The Series' equity
holdings  consist  primarily of common  stocks,  but may also include  preferred
stocks and  investment  grade  securities  convertible  into  common  stocks and
warrants.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk. Because the Series invests primarily in stocks of
                  U.S.  companies,  it is subject to stock  market  risk.  Stock
                  prices typically fluctuate more than the values of other types
                  of  securities,  typically  in  response  to  changes  in  the
                  particular company's financial condition and factors affecting
                  the  market  in   general.   For   example,   unfavorable   or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

         o        Small cap  investing.  Investing in smaller,  newer  companies
                  generally  involves  greater  risks than  investing in larger,
                  more  established  ones.  The companies in which the Series is
                  likely  to invest  have  limited  product  lines,  markets  or
                  financial  resources,  or may depend on the expertise of a few
                  people  and may be subject  to more  abrupt or erratic  market
                  movements  than   securities  of  larger,   more   established
                  companies or the market averages in general. In addition, many
                  small  capitalization  companies may be in the early stages of
                  development.  Accordingly, an investment in the Series may not
                  be appropriate for all investors.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

JNL/J.P. Morgan Enhanced S&P 500 Stock Index Series

Investment Objective.  The investment objective of the JNL/J.P.  Morgan Enhanced
S&P 500 Stock  Index  Series is to  provide  high  total  return  from a broadly
diversified portfolio of equity securities.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing    primarily    in   a    diversified    portfolio   of   large-   and
medium-capitalization  U.S. companies.  At least 65% of its total assets will be
invested,  under normal market  conditions,  in stocks.  The Series owns a large
number of stocks  within the Standard & Poor's 500  Composite  Stock Price Index
(S&P 500 Index), generally tracking the industry weighting of that Index. Within
each  industry,  the Series  modestly  overweights  stocks that the  sub-adviser
regards as  undervalued or fairly valued and modestly  underweights  or does not
hold stocks that the  sub-adviser  determines are overvalued.  By so doing,  the
Series seeks  returns that  slightly  exceed those of the S&P 500 Index over the
long term with  virtually  the same level of  volatility.  The  Series'  foreign
investments  generally  reflect the weightings of foreign  securities in the S&P
500 Index.

In  managing  the  JNL/J.P.  Morgan  Enhanced  S&P 500 Stock Index  Series,  the
sub-adviser generally employs a three-step process:

         (i)      based  on its  in-house  research,  the  sub-adviser  takes an
                  in-depth  look at company  prospects  over a  relatively  long
                  period,  often as much as five years,  rather than focusing on
                  near-term  expectations.  This approach is designed to provide
                  insight into a company's real growth potential.

         (ii)     the  research  findings  allow  the  sub-adviser  to rank  the
                  companies in each industry  group  according to their relative
                  value.  These valuation rankings are produced with the help of
                  models that quantify the research team's findings.

         (iii)    the sub-adviser buys and sells stocks for the Series according
                  to the policies of the Series  based on the sub-  research and
                  valuation rankings.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series invests in stocks of U.S. and
                  foreign  companies,  it is subject to stock market risk. Stock
                  prices typically fluctuate more than the values of other types
                  of  securities,  typically  in  response  to  changes  in  the
                  particular company's financial condition and factors affecting
                  the  market  in   general.   For   example,   unfavorable   or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

COMPARABLE PERFORMANCE

Private Account Performance Composite

The  JNL/J.P.  Morgan  Enhanced  S&P 500 Stock  Index  Series has  substantially
similar  investment  objectives,  policies and investment  strategies as certain
Private  Accounts.  Each of these  Private  Accounts  is managed by J.P.  Morgan
Investment  Management  Inc.,  the same  Sub-Adviser  which  manages each of the
corresponding Series.

The  historical  performance  of each of these Private  Accounts is shown below.
This  performance  data  should not be  considered  as an  indication  of future
performance of the Series. The Private Account performance figures shown below:

o        do not reflect  Contract  fees or charges  imposed by Jackson  National
         Life.  Investors  should refer to the separate  account  prospectus for
         information  describing  the Contract fees and charges.  These fees and
         charges will have a detrimental effect on Series performance.

The Series  and  Private  Accounts  are  expected  to hold  similar  securities.
However,  their  investment  results are  expected  to differ for the  following
reasons:

o        differences  in asset size and cash flow  resulting  from purchases and
         redemptions   of  Series  shares  may  result  in  different   security
         selections

o differences in the relative weightings of securities

o differences in the price paid for particular portfolio holdings

o differences relating to certain tax matters

o        differences in that such Accounts are not subject to certain investment
         limitations,   diversification   requirements  and  other  restrictions
         imposed by federal tax and securities laws

However,  the differences  cited do not alter the conclusion that the funds have
substantially similar investment objectives, policies and strategies.

performance of Private Accounts.

subject  to  investment  limitations,  diversification  requirements,  and other
restrictions  imposed on mutual funds by the 1940 Act and the  Internal  Revenue
Code. The performance of the accounts might have been lower if they were subject
to these extra restrictions. Note also that the performance shown would be lower
upon taking into account charges  assessed in connection with a variable annuity
or variable life contract.

Composite  returns  reflect the deduction of the highest fee J.P. Morgan charges
for the strategy.  The fee deducted by J.P.  Morgan is less than the fees of the
Series. If the expenses of the Series had been deducted, the performance results
would have been lower.  Actual  account  performance  will vary depending on the
size of a portfolio and  applicable  fee  schedule.  Past  performance  does not
guarantee future results.

The  following is an example of the effect of  compounded  advisory  fees over a
period  of time  on the  value  of a  client's  portfolio:  A  portfolio  with a
beginning value of $100, gaining an annual return of 10% per annum would grow to
$259  after 10  years,  assuming  no fees have  been  paid  out.  Conversely,  a
portfolio  with a beginning  value of $100,  gaining an annual return of 10% per
annum, but paying a fee of 1% per annum, would only grow to $235 after 10 years.
The  annualized  returns over the 10 year time period are 10.00% (gross of fees)
and 8.91% (net of fees).  If the fee in the above  example  was 0.25% per annum,
the  portfolio  would grow to $253 after 10 years and return  9.73% net of fees.
The fees were  calculated on a monthly basis,  which shows the maximum effect of
compounding.

A Series'  performance  may be  affected by risks  specific to certain  types of
investments, such as foreign securities, derivative investments,  non-investment
grade  debt  securities,  initial  public  offerings  (IPOs) or  companies  with
relatively small market  capitalizations.  IPOs and other investment  techniques
may have  magnified  performance  impact on a Series with a small asset base.  A
Series may not experience similar performance as its assets grow.

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the  Series.  In  general,  the  sub-adviser  buys  stocks  that it
identifies  as  undervalued   and  considers   selling  them  when  they  appear
overvalued.  Along  with  attractive  valuation,  the  Series'  sub-adviser  may
consider  other  criteria,  such as:  catalysts  that could  trigger a rise in a
stock's price;  high potential  reward compared to potential risk; and temporary
mispricings caused by market overreactions.  Under normal market conditions, the
Series  holds  approximately  300 stocks and limits each  stock's  weight in the
portfolio to be within +/- 1.0% of its weight in the S&P 500 Index.

The Series may invest up to 100% of its assets in  investment-grade,  short-term
fixed-income securities during severe market downturns.  Doing so may reduce the
potential for appreciation in the Series' portfolio. The Series generally avoids
short-term  trading,  except  to take  advantage  of  attractive  or  unexpected
opportunities  or to meet demands  generated  by  shareholder  activity.  Active
trading may increase transaction costs, which may reduce performance.

The Series may use derivative instruments,  such as futures contracts,  options,
forward currency contracts and swaps, for hedging and risk management,  i.e., to
establish  or adjust  exposure to the equities  market.  These  instruments  are
subject to transaction costs and certain risks, such as unanticipated changes in
securities prices and global currency markets.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

JNL/J.P. Morgan International & Emerging Markets Series

Investment   Objective.   The  investment  objective  of  the  JNL/J.P.   Morgan
International  & Emerging  Markets Series is to provide high total return from a
portfolio of equity  securities  of foreign  companies  in  developed  and, to a
lesser extent, developing markets.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  primarily in a  diversified  portfolio  of common  stocks of non-U.S.
companies  in  developed  markets.  At least  65% of its  total  assets  will be
invested,  under  normal  market  conditions,  in equity  securities  of foreign
issuers.  The Series  also  invests in the equity  securities  of  companies  in
developing countries or "emerging markets." The sub-adviser  considers "emerging
markets" to be any country generally  considered to be an emerging or developing
country by the World Bank, the International  Finance  Corporation or the United
Nations or its authorities. An issuer in an emerging market is one that: (i) has
its principal  securities trading market in an emerging market country;  (ii) is
organized under the laws of an emerging market; (iii) derives 50% or more of its
total revenue from either goods  produced,  sales made or services  performed in
emerging  markets;  or (iv) has at least 50% of its assets  located in  emerging
markets.

The Series focuses its emerging market  investments in those countries which the
sub-adviser believes have strongly developing economies and in which the markets
are becoming more sophisticated.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series  invests in stocks of foreign
                  companies,  it is subject to stock market  risk.  Stock prices
                  typically  fluctuate  more than the  values of other  types of
                  securities, typically in response to changes in the particular
                  company's financial condition and factors affecting the market
                  in general.  For example,  unfavorable or  unanticipated  poor
                  earnings performance of the company may result in a decline in
                  its  stock's  price,  and a  broad-based  market drop may also
                  cause a stock's price to fall.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in  securities  of issuers in emerging  markets,  which
                  involves  greater risk.  Emerging market  countries  typically
                  have  economic  and  political  systems  that are  less  fully
                  developed,  and likely to be less  stable,  than those of more
                  advanced   countries.   Emerging  market  countries  may  have
                  policies that restrict investment by foreigners,  and there is
                  a higher risk of a government taking private property.  Low or
                  nonexistent   trading  volume  in  securities  of  issuers  in
                  emerging  markets  may  result in a lack of  liquidity  and in
                  price  volatility.  Issuers in emerging markets  typically are
                  subject to a greater degree of change in earnings and business
                  prospects than are companies in developed markets.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

         o        Derivatives risk. Investing in derivative instruments, such as
                  options,   futures  contracts,   forward  currency  contracts,
                  indexed  securities  and  asset-backed  securities,   involves
                  special risks. The Series  sub-adviser must correctly  predict
                  price  movements,  during  the  life of a  derivative,  of the
                  underlying  asset in order to realize the desired results from
                  the investment. The value of derivatives may rise or fall more
                  rapidly  than  other  investments,   which  may  increase  the
                  volatility of the Series depending on the nature and extent of
                  the derivatives in the Series'  portfolio.  If the sub-adviser
                  uses  derivatives  in  attempting  to  manage or  "hedge"  the
                  overall  risk of the  portfolio,  the  strategy  might  not be
                  successful,  for  example,  due to changes in the value of the
                  derivatives  that do not correlate with price movements in the
                  rest of the portfolio.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series.  The JNL/J.P.  Morgan  International & Emerging Markets
Series seeks to achieve its  investment  objective  primarily  through its stock
selection  process.  Using a variety of  quantitative  valuation  techniques and
based on in-house  research,  the sub-adviser ranks issuers within each industry
group  according to their  relative  value.  The  sub-adviser  makes  investment
decisions using the research and valuation ranking, as well as its assessment of
other  factors,  including:  catalysts  that could trigger a change in a stock's
price;  potential  reward compared to potential risk, and temporary  mispricings
caused by market  overreactions.  The Series' country  allocation and industrial
sector  weightings  result primarily from its stock selection  decisions and may
vary  significantly  from the MSCI All Country World Free (ex-U.S.)  Index,  the
Series' benchmark.

Under  normal  market  conditions,   the  Series  may  invest  in  money  market
instruments to invest  temporary cash balances or to maintain  liquidity to meet
redemptions.  The  Series  may also  invest  in money  market  instruments  as a
temporary  defensive measure when, in the sub-adviser's  view, market conditions
are, or are  anticipated to be,  adverse.  Doing so may reduce the potential for
appreciation in the Series' portfolio.

The  sub-adviser  manages  the Series  actively  in  pursuit  of its  investment
objective.  Active  trading may  increase  transaction  costs,  which may reduce
performance.

The Series may use derivative  instruments,  such as futures contracts,  options
and  forward  currency  contracts,  for  hedging  and  risk  management.   These
instruments  are  subject  to  transaction  costs  and  certain  risks,  such as
unanticipated  changes in interest rates,  securities prices and global currency
markets.

The Series may invest in when-issued  and delayed  delivery  securities.  Actual
payment for and delivery of such  securities does not take place until some time
in the future, i.e., beyond normal settlement.  The purchase of these securities
will result in a loss if their value declines prior to the settlement date. This
could occur, for example, if interest rates increase prior to settlement.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

The Sub-Adviser and Portfolio Management. The sub-adviser to the JNL/J.P. Morgan
International  & Emerging  Markets Series is J.P. Morgan  Investment  Management
Inc. (J.P.  Morgan),  with principal offices at 522 Fifth Avenue,  New York, New
York 10036.  J.P.  Morgan and its  affiliates  offer a wide range of services to
governmental,  institutional,  corporate  and  individual  customers  and act as
investment adviser to individual and institutional customers.

The  Series  has a  portfolio  management  team  that  is  responsible  for  the
day-to-day  management of the Series.  The portfolio  management  team is led by
Paul A.  Quinsee,  Managing  Director of J.P.  Morgan,  Andrew C.  Cormie,  Vice
President of J.P.  Morgan,  and Nigel F. Emmett,  Vice President of J.P. Morgan.
Mr.  Quinsee has been at J.P.  Morgan  since 1992 and has been on the  portfolio
management  team  since the  inception  of the  Series.  Mr.  Cormie has been an
international  equity  portfolio  manager since 1997 and employed by J.P. Morgan
since 1984. Mr. Emmett joined J.P. Morgan in August 1997;  prior to that, he was
an assistant  manager at Brown Brothers Harriman and Co. and a portfolio manager
at Gartmore  Investment  Management.  Mr. Cormie and Mr. Emmett have been on the
portfolio management team for the Series since the inception of the Series.

JNL/Janus Aggressive Growth Series

Investment  Objective.  The  investment  objective of the  JNL/Janus  Aggressive
Growth Series is long-term growth of capital.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  primarily in a  diversified  portfolio  of common  stocks of U.S. and
foreign companies selected for their growth potential.  The JNL/Janus Aggressive
Growth Series invests  primarily in common stocks when the sub-adviser  believes
that the  relevant  market  environment  favors  profitable  investing  in those
securities.  The  Series  may  invest in  companies  of any size,  from  larger,
well-established   companies  to  smaller,   emerging  growth   companies.   The
sub-adviser  seeks  to  identify  individual   companies  with  earnings  growth
potential  that may not be recognized  by the market.  The  sub-adviser  selects
securities  for  their  capital  growth  potential;  investment  income is not a
consideration.  When the  sub-adviser  believes that market  conditions  are not
favorable for profitable  investing or when the sub-adviser is otherwise  unable
to  locate  favorable  investment  opportunities,   the  Series  may  hedge  its
investments to a greater degree and/or  increase its position in cash or similar
investments.  Doing so may reduce the potential for  appreciation in the Series'
portfolio.

The Series may invest to a lesser degree in other types of securities, including
preferred  stock,  warrants,  convertible  securities and debt  securities.  The
Series may invest without limit in foreign securities.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series invests in stocks of U.S. and
                  foreign  companies,  it is subject to stock market risk. Stock
                  prices typically fluctuate more than the values of other types
                  of  securities,  typically  in  response  to  changes  in  the
                  particular company's financial condition and factors affecting
                  the  market  in   general.   For   example,   unfavorable   or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.  Investing
                  in smaller,  newer companies  generally involves greater risks
                  than investing in larger, more established ones.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those  held by the  Series,  will  fall.  A
                  broad-based market drop may also cause a bond's price to fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date. Growth investing risk. Growth companies usually invest a
                  high portion of earnings in their businesses, and may lack the
                  dividends of value stocks that can cushion prices in a falling
                  market.  Also,  earnings  disappointments  often lead to sharp
                  declines  in prices  because  investors  buy growth  stocks in
                  anticipation of superior earnings growth.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

         o        Derivatives risk. Investing in derivative instruments, such as
                  options,   futures  contracts,   forward  currency  contracts,
                  indexed  securities  and  asset-backed  securities,   involves
                  special risks. The Series  sub-adviser must correctly  predict
                  price  movements,  during  the  life of a  derivative,  of the
                  underlying  asset in order to realize the desired results from
                  the investment. The value of derivatives may rise or fall more
                  rapidly  than  other  investments,   which  may  increase  the
                  volatility of the Series depending on the nature and extent of
                  the derivatives in the Series'  portfolio.  If the sub-adviser
                  uses  derivatives  in  attempting  to  manage or  "hedge"  the
                  overall  risk of the  portfolio,  the  strategy  might  not be
                  successful,  for  example,  due to changes in the value of the
                  derivatives  that do not correlate with price movements in the
                  rest of the portfolio.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series. The Series may invest in "special situations" from time
to time. A special situation arises when, in the opinion of the sub-adviser, the
securities of a particular issuer will be recognized and appreciate in value due
to a specific  development  with respect to that issuer.  Developments  creating
special  situations  might include,  among others,  a new product or process,  a
technological breakthrough, a management change or other extraordinary corporate
event,  or  differences  in  market  supply  of and  demand  for  the  security.
Investment in special  situations  may carry an  additional  risk of loss in the
event that the  anticipated  development  does not occur or does not attract the
expected attention. The impact of this strategy on the Series will depend on the
Series'  size and the  extent  of its  holdings  of  special  situation  issuers
relative to total net assets.

The Series may use derivative instruments,  such as futures contracts,  options,
and forward currency  contracts,  for hedging or as a means of enhancing return.
These  instruments are subject to transaction  costs and certain risks,  such as
unanticipated  changes in interest rates,  securities prices and global currency
markets.

The  Series  may  invest  in  high-yield,  high-risk,  fixed-income  securities,
commonly known as "junk bonds." These are corporate debt securities rated BBB or
lower by S&P or Baa or lower by  Moody's,  or unrated  securities  deemed by the
sub-adviser  to be  of  comparable  quality.  Lower-rated  securities  generally
involve a higher risk of default than higher-rated ones.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

JNL/Janus Balanced Series

Investment Objective.  The investment objective of the JNL/Janus Balanced Series
is  long-term  capital  growth,  consistent  with  preservation  of capital  and
balanced by current income.

Principal  Investment  Strategies.  The Series  normally  invests  40-60% of its
assets in securities selected primarily for their growth potential and 40-60% of
its assets in  securities  selected  primarily for their income  potential.  The
JNL/Janus   Balanced  Series  invests   primarily  in  common  stocks  when  the
sub-adviser  believes that the relevant  market  environment  favors  profitable
investing in those  securities.  The  sub-adviser  seeks to identify  individual
companies  with  earnings  growth  potential  that may not be  recognized by the
market.  The sub-adviser  selects securities for their capital growth potential.
The sub-adviser may also consider dividend-paying characteristics when selecting
common  stock.  When the  sub-adviser  believes that market  conditions  are not
favorable for profitable  investing or when the sub-adviser is otherwise  unable
to  locate  favorable  investment  opportunities,   the  Series  may  hedge  its
investments to a greater degree and/or  increase its position in cash or similar
investments.  Doing so may reduce the potential for  appreciation in the Series'
portfolio.  The  Series  will  normally  invest  at least  25% of its  assets in
fixed-income  securities.  The  Series  may  invest  without  limit  in  foreign
securities.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series invests in stocks of U.S. and
                  foreign  companies,  it is subject to stock market risk. Stock
                  prices typically fluctuate more than the values of other types
                  of  securities,  typically  in  response  to  changes  in  the
                  particular company's financial condition and factors affecting
                  the  market  in   general.   For   example,   unfavorable   or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.  Investing
                  in smaller,  newer companies  generally involves greater risks
                  than investing in larger, more established ones.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those  held by the  Series,  will  fall.  A
                  broad-based  market  drop may also  cause a  stock's  price to
                  fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information, more volatile or less liquid markets. Investments
                  in foreign  countries could be affected by factors not present
                  in the U.S.,  such as restrictions on receiving the investment
                  proceeds  from  a  foreign  country,  foreign  tax  laws,  and
                  potential  difficulties in enforcing contractual  obligations.
                  Transactions  in  foreign  securities  may be  subject to less
                  efficient settlement  practices,  including extended clearance
                  and  settlement  periods.   Foreign  accounting  may  be  less
                  revealing   than  American   accounting   practices.   Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Comparable Performance.

Public Fund/Private Account Performance Composite

The JNL/Janus Balanced Series has substantially  similar investment  objectives,
policies and  strategies as certain mutual funds and Private  Accounts.  Each of
these  public  mutual  funds and Private  Accounts  is managed by Janus  Capital
Corporation, the same Sub-Adviser which manages the JNL/Janus Balanced Series.

The  historical  performance  of a composite  of these  public  mutual funds and
Private  Accounts is shown below.  This is not the  performance of the JNL/Janus
Balanced Series and the performance of the Series may differ.  This  performance
data should not be  considered as an  indication  of future  performance  of the
Series.  The public mutual fund and Private  Account  performance  figures shown
below:

         o        reflect the deduction of the historical fees and expenses paid
                  by the  public  mutual  funds  and not those to be paid by the
                  Series.

         o        do not  reflect  Contract  fees or charges  imposed by Jackson
                  National Life.  Investors should refer to the separate account
                  prospectus  for  information  describing the Contract fees and
                  charges. These fees and charges will have a detrimental effect
                  on Series performance.

The  Series and their  corresponding  public  mutual  fund  series  and  Private
Accounts are  expected to hold similar  securities.  However,  their  investment
results are expected to differ for the following reasons:

         o        differences  in  asset  size  and  cash  flow  resulting  from
                  purchases  and  redemptions  of Series  shares  may  result in
                  different security selections

         o        differences in the relative weightings of securities

         o        differences  in  the  price  paid  for  particular   portfolio
                  holdings

         o        differences relating to certain tax matters

         o        differences  (with  respect to the Private  Accounts)  in that
                  such   Accounts   are  not   subject  to  certain   investment
                  limitations,    diversification    requirements    and   other
                  restrictions imposed by federal tax and securities laws

However,  the differences  cited do not alter the conclusion that the Funds have
substantially similar investment objectives, policies and strategies.

The chart below shows performance  information derived from historical composite
performance of the public mutual funds and Private Accounts.  The inception date
for the composite shown is January 1, 1988.

*Inception January 1, 1988

The Balanced  Composite  includes  all fully  discretionary  separately  managed
balanced accounts and mutual funds for which Janus Capital Corporation serves as
investment advisor.  The composite was calculated  according to the requirements
of the Association for Investment  Management and Research.  These  requirements
differ from those required by the Securities and Exchange Commission.  Composite
performance is presented net of all fees and reflects  reinvestment of dividends
and  capital  gains.  The fees  deducted  are less than the fees  charged by the
Series. If the expenses of the Series had been deducted, the performance results
would have been lower. As of December 31, 1999, the Balanced  Composite included
12 accounts and assets of $6,419.1  million,  which  represented  2.57% of total
assets under  management.  The  percentage of total assets managed is defined as
composite  assets as a percentage of the total assets managed  including  mutual
fund  company  accounts  under  management.  Performance  figures are based upon
historical  information and do not guarantee  future results.  In addition,  the
managers  responsible  for the historical  performance  record of these accounts
(Blaine Rollins and James Craig) assumed new responsibilities at Janus beginning
January 1, 2000.  Karen  Reidy is now the  Portfolio  Manager  for all  Balanced
Products.  No changes will be made with regard to the  investment  philosophy or
process of the Funds or separate accounts.  Prospective clients should recognize
the limitations inherent in composites,  and consider all information  presented
by Janus  regarding its investment  management  capabilities.  The S&P 500 is an
unmanaged  index of common stock prices and includes  reinvestment  of dividends
and capital gains. They have been taken from published sources and have not been
audited.  Composition of each separately  managed  account  portfolio may differ
significantly from securities in the corresponding benchmark indices. A complete
list of Janus composites is available upon request. Please call 800-525-1068.

A Series'  performance  may be  affected by risks  specific to certain  types of
investments, such as foreign securities, derivative investments,  non-investment
grade  debt  securities,  initial  public  offerings  (IPOs) or  companies  with
relatively small market  capitalizations.  IPOs and other investment  techniques
may have  magnified  performance  impact on a Series with a small asset base.  A
Series may not experience similar performance as its assets grow.

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series. The Series may invest in "special situations" from time
to time. A special situation arises when, in the opinion of the sub-adviser, the
securities of a particular issuer will be recognized and appreciate in value due
to a specific  development  with respect to that issuer.  Developments  creating
special  situations  might include,  among others,  a new product or process,  a
technological breakthrough, a management change or other extraordinary corporate
event,  or  differences  in  market  supply  of and  demand  for  the  security.
Investment in special  situations  may carry an  additional  risk of loss in the
event that the  anticipated  development  does not occur or does not attract the
expected attention. The impact of this strategy on the Series will depend on the
Series'  size and the  extent  of its  holdings  of  special  situation  issuers
relative to total net assets.

The Series may use derivative instruments,  such as futures contracts,  options,
and forward currency  contracts,  for hedging or as a means of enhancing return.
These  instruments are subject to transaction  costs and certain risks,  such as
unanticipated  changes in interest rates,  securities prices and global currency
markets.

The  Series  may  invest  in  high-yield,  high-risk,  fixed-income  securities,
commonly known as "junk bonds." These are corporate debt securities rated BBB or
lower by S&P or Baa or lower by  Moody's,  or unrated  securities  deemed by the
sub-adviser  to be  on  comparable  quality.  Lower-rated  securities  generally
involve a higher risk of default than higher-rated ones.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

The  Sub-Adviser  and Portfolio  Management.  The  sub-adviser  to the JNL/Janus
Balanced Series is Janus Capital  Corporation  (Janus  Capital),  with principal
offices at 100 Fillmore Street,  Denver,  Colorado 80206. Janus Capital provides
investment advisory services to mutual funds and other institutional accounts.

Karen L. Reidy is the Portfolio Manager of the Series. She is also the portfolio
manager and  Executive  Vice  President of Janus  Balanced Fund and Janus Equity
Income  Fund,  as well as Janus Aspen  Balanced  and Janus Aspen  Equity  Income
Portfolios. She is also an Assistant Portfolio Manager of Janus Fund and manages
separate accounts and sub-advised  portfolios in the Balanced discipline.  Prior
to joining Janus in 1995,  Ms. Reidy worked for Price  Waterhouse in the Mergers
and  Acquisitions  area,  performing  corporate due  diligence,  and as an audit
manager,  analyzing financials for corporate clients. Before assuming management
responsibilities  of Janus Balanced Fund and Janus Equity Income Fund in January
2000,  Ms. Reidy was  Assistant  Portfolio  Manager of Janus Fund,  focusing her
research on large-capitalization companies. Ms. Reidy earned a bachelor's degree
in accounting from the University of Colorado.  She passed the Certified  Public
Accountant exam in 1992 and has earned the right to use the Chartered  Financial
Analyst designation. She has five years of professional investment experience.

JNL/Janus Capital Growth Series

Investment  Objective.  The investment objective of the JNL/Janus Capital Growth
Series  is  long-term  growth  of  capital  in  a  manner  consistent  with  the
preservation of capital.

Principal  Investment  Strategies.  The Series  seeks to achieve  its  objective
through a non-diversified portfolio consisting primarily of common stock of U.S.
and foreign  companies  selected for their growth potential and normally invests
at least  50% of its  equity  assets  in  medium-sized  companies.  Medium-sized
companies  are those  whose  market  capitalizations  fall  within  the range of
companies  in the S&P  MidCap  400 Index and are  determined  at the time  their
securities  are acquired by the Series.  The market  capitalizations  within the
Index will vary, but as of December 31, 1999, they ranged between  approximately
$170  million and $37  billion.  The  sub-adviser  seeks to identify  individual
companies  with  earnings  growth  potential  that may not be  recognized by the
market.  The sub-adviser  selects securities for their capital growth potential;
investment  income is not a  consideration.  When the sub-adviser  believes that
market  conditions  are not  favorable  for  profitable  investing  or when  the
sub-adviser is otherwise  unable to locate favorable  investment  opportunities,
the Series may hedge its  investments  to a greater  degree and/or  increase its
position in cash or similar  investments.  Doing so may reduce the potential for
appreciation in the Series' portfolio.

The Series  normally  invests a majority  of its equity  assets in  medium-sized
companies.  The  Series  may  invest  to a  lesser  degree  in  other  types  of
securities, including preferred stock, warrants, convertible securities and debt
securities. The Fund may invest without limit in foreign securities.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series invests in stocks of U.S. and
                  foreign  companies,  it is subject to stock market risk. Stock
                  prices typically fluctuate more than the values of other types
                  of  securities,  typically  in  response  to  changes  in  the
                  particular company's financial condition and factors affecting
                  the  market  in   general.   For   example,   unfavorable   or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those  held by the  Series,  will  fall.  A
                  broad-based market drop may also cause a bond's price to fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Growth investing risk.  Growth companies usually invest a high
                  portion  of  earnings  in their  businesses,  and may lack the
                  dividends of value stocks that can cushion prices in a falling
                  market.  Also,  earnings  disappointments  often lead to sharp
                  declines  in prices  because  investors  buy growth  stocks in
                  anticipation of superior earnings growth.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in  larger  proportions  of  assets  of  single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

JNL/Janus Global Equities Series*


Investment Objective.  The investment objective of the JNL/Janus Global Equities
Series  is  long-term  growth  of  capital  in  a  manner  consistent  with  the
preservation of capital.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing at least 65% in a  diversified  portfolio of common  stocks of foreign
and domestic  issuers.  The sub-adviser seeks to identify  individual  companies
with  earnings  growth  potential  that may not be  recognized  by the market at
large. The sub-adviser  selects  securities for their capital growth  potential;
investment  income is not a  consideration.  When the sub-adviser  believes that
market  conditions  are not  favorable  for  profitable  investing  or when  the
sub-adviser is otherwise  unable to locate favorable  investment  opportunities,
the Series may hedge its  investments  to a greater  degree and/or  increase its
position in cash or similar  investments.  Doing so may reduce the potential for
appreciation in the Series' portfolio.

The Series may invest to a lesser degree in other types of securities, including
preferred stock, warrants,  convertible securities, and debt securities, such as
corporate  bonds.  The Series can invest on a worldwide  basis in companies  and
other organizations of any size,  regardless of country of organization or place
of principal  business  activity,  as well as domestic and foreign  governments,
government agencies and other governmental entities. The Series normally invests
in securities of issuers from at least five different  countries,  including the
United States,  although it may invest in fewer than five countries.  The Series
may invest without limit in foreign securities.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series invests in stocks of U.S. and
                  foreign  companies,  it is subject to stock market risk. Stock
                  prices typically fluctuate more than the values of other types
                  of  securities,  typically  in  response  to  changes  in  the
                  particular company's financial condition and factors affecting
                  the  market  in   general.   For   example,   unfavorable   or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those  held by the  Series,  will  fall.  A
                  broad-based market drop may also cause a bond's price to fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.


         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.  To the extent that
                  the Series  invests in bonds  issued by a foreign  government,
                  the Series may have  limited  legal  recourse  in the event of
                  default.   Political   conditions,   especially   a  country's
                  willingness  to meet the  terms of its debt  obligations,  can
                  create special risks.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

         o        Derivatives risk. Investing in derivative instruments, such as
                  options,   futures  contracts,   forward  currency  contracts,
                  indexed  securities  and  asset-backed  securities,   involves
                  special risks. The Series  sub-adviser must correctly  predict
                  price  movements,  during  the  life of a  derivative,  of the
                  underlying  asset in order to realize the desired results from
                  the investment. The value of derivatives may rise or fall more
                  rapidly  than  other  investments,   which  may  increase  the
                  volatility of the Series depending on the nature and extent of
                  the derivatives in the Series'  portfolio.  If the sub-adviser
                  uses  derivatives  in  attempting  to  manage or  "hedge"  the
                  overall  risk of the  portfolio,  the  strategy  might  not be
                  successful,  for  example,  due to changes in the value of the
                  derivatives  that do not correlate with price movements in the
                  rest of the portfolio.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series. The Series may invest in "special situations" from time
to time. A special situation arises when, in the opinion of the sub-adviser, the
securities of a particular issuer will be recognized and appreciate in value due
to a specific  development  with respect to that issuer.  Developments  creating
special  situations  might include,  among others,  a new product or process,  a
technological breakthrough, a management change or other extraordinary corporate
event,  or  differences  in  market  supply  of and  demand  for  the  security.
Investments in special  situations  may carry an additional  risk of loss in the
event that the  anticipated  development  does not occur or does not attract the
expected attention. The impact of this strategy on the Series will depend on the
Series'  size and the  extent  of its  holdings  of  special  situation  issuers
relative to total net assets.

The Series may use derivative instruments,  such as futures contracts,  options,
and forward currency  contracts,  for hedging or as a means of enhancing return.
These  instruments are subject to transaction  costs and certain risks,  such as
unanticipated  changes in interest rates,  securities prices and global currency
markets.

The Series may invest in high-yield, high-risk fixed-income securities, commonly
known as "junk bonds." These are corporate debt securities rated BBB or lower by
S&P or Baa or lower by Moody's,  or unrated securities deemed by the sub-adviser
to be of comparable quality.  Lower-rated  securities generally involve a higher
risk of default, and may fluctuate more in value than higher-rated securities.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

The  Sub-Adviser  and Portfolio  Management.  The  sub-adviser  to the JNL/Janus
Global  Equities  Series is Janus  Capital  Corporation  (Janus  Capital),  with
principal offices at 100 Fillmore Street, Denver,  Colorado 80206. Janus Capital
provides  investment  advisory services to mutual funds and other  institutional
accounts.

Helen Young Hayes,  Portfolio  Manager of Janus Capital,  is responsible for the
day-to-day management of the Series. Ms. Hayes joined Janus Capital in 1987. She
holds a Bachelor of Arts in Economics  from Yale  University  and has earned the
right to use the  Chartered  Financial  Analyst  designation.  Ms. Hayes has had
responsibility  for the day-to-day  management of the Series since the inception
of the Series.

JNL/Janus Growth & Income Series (formerly the Goldman Sachs/JNL Growth & Income
Series)

Investment Objective. The investment objectives of the JNL/Janus Growth & Income
Series are long-term capital growth and current income.

Principal Investment  Strategies.  The Series normally emphasizes investments in
common  stocks.  It will  normally  invest  up to 75% of its  assets  in  equity
securities  selected  primarily for their growth potential,  and at least 25% of
its assets in securities the portfolio  manager believes have income  potential.
The  sub-adviser  seeks to identify  individual  companies with earnings  growth
potential  that may not be recognized  by the market.  The  sub-adviser  selects
securities for their capital growth potential. The sub-adviser may also consider
dividend-paying   characteristics   when  selecting   common  stock.   When  the
sub-adviser  believes that market  conditions  are not favorable for  profitable
investing  or when the  sub-adviser  is  otherwise  unable to  locate  favorable
investment  opportunities,  the  Series may hedge its  investments  to a greater
degree and/or increase its position in cash or similar investments. Doing so may
reduce  the  potential  for  appreciation  in  the  Series'  portfolio.   Equity
securities  may make up part of this  income  component  if they  currently  pay
dividends or the portfolio  manager  believes they have potential for increasing
or commencing dividend payments.  The Series may invest without limit in foreign
securities.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series invests in stocks of U.S. and
                  foreign  companies,  it is subject to stock market risk. Stock
                  prices typically fluctuate more than the values of other types
                  of  securities,  typically  in  response  to  changes  in  the
                  particular company's financial condition and factors affecting
                  the  market  in   general.   For   example,   unfavorable   or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.  Investing
                  in smaller,  newer companies  generally involves greater risks
                  than investing in larger, more established ones.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those  held by the  Series,  will  fall.  A
                  broad-based  market  drop may also  cause a  stock's  price to
                  fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information, more volatile or less liquid markets. Investments
                  in foreign  countries could be affected by factors not present
                  in the U.S.,  such as restrictions on receiving the investment
                  proceeds  from  a  foreign  country,  foreign  tax  laws,  and
                  potential  difficulties in enforcing contractual  obligations.
                  Transactions  in  foreign  securities  may be  subject to less
                  efficient settlement  practices,  including extended clearance
                  and  settlement  periods.   Foreign  accounting  may  be  less
                  revealing   than  American   accounting   practices.   Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

         o        Derivatives risk. Investing in derivative instruments, such as
                  options,   futures  contracts,   forward  currency  contracts,
                  indexed  securities  and  asset-backed  securities,   involves
                  special risks. The Series  sub-adviser must correctly  predict
                  price  movements,  during  the  life of a  derivative,  of the
                  underlying  asset in order to realize the desired results from
                  the investment. The value of derivatives may rise or fall more
                  rapidly  than  other  investments,   which  may  increase  the
                  volatility of the Series depending on the nature and extent of
                  the derivatives in the Series'  portfolio.  If the sub-adviser
                  uses  derivatives  in  attempting  to  manage or  "hedge"  the
                  overall  risk of the  portfolio,  the  strategy  might  not be
                  successful,  for  example,  due to changes in the value of the
                  derivatives  that do not correlate with price movements in the
                  rest of the portfolio. Growth investing risk. Growth companies
                  usually invest a high portion of earnings in their businesses,
                  and may lack the  dividends  of value  stocks that can cushion
                  prices in a falling  market.  Also,  earnings  disappointments
                  often lead to sharp declines in prices  because  investors buy
                  growth stocks in anticipation of superior earnings growth.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

has varied from year to year. The table shows the Series' average annual returns
and compares them to a broad based index since these shares were first  offered.
Both the chart and the table assume reinvestment of dividends and distributions.
The  Series'  returns  shown in the  chart and table  below do not  reflect  the
deduction of any charges that are imposed under a variable  insurance  contract.
Those charges,  which are described in the variable insurance  prospectus,  will
reduce the Series' performance.

As of the effective date of this Prospectus,  Janus Capital  Corporation (Janus)
has replaced  Goldman Sachs Asset  Management as the sub-adviser to this Series.
In addition,  certain  investment  policies,  practices and strategies have been
changed to reflect  the  management  style of Janus,  the new  sub-adviser.  The
advisory  fees have also been  changed.  Given these  changes,  the  performance
information  shown below is not  indicative in any manner of how the Series will
perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Comparable Performance.

Public Fund Performance Composite

The  JNL/Janus  Growth & Income  Series  has  substantially  similar  investment
objectives,  policies and  strategies  as certain  mutual  funds.  Each of these
public  mutual  funds  is  managed  by  Janus  Capital  Corporation,   the  same
Sub-Adviser which manages the JNL/Janus Growth & Income Series.

The historical  performance of a composite of these public mutual funds is shown
below.  This is not the performance of the JNL/Janus  Growth & Income Series and
the performance of the Series may differ.  This  performance  data should not be
considered  as an  indication of future  performance  of the Series.  The public
mutual fund performance figures shown below:

         o        reflect the deduction of the historical fees and expenses paid
                  by the  public  mutual  funds  and not those to be paid by the
                  Series

         o        do not  reflect  Contract  fees or charges  imposed by Jackson
                  National Life.  Investors should refer to the separate account
                  prospectus  for  information  describing the Contract fees and
                  charges. These fees and charges will have a detrimental effect
                  on Series performance.

The Series and their  corresponding  public  mutual fund series are  expected to
hold  similar  securities.  However,  their  investment  results are expected to
differ for the following reasons:

         o        differences  in  asset  size  and  cash  flow  resulting  from
                  purchases  and  redemptions  of Series  shares  may  result in
                  different security selections

         o        differences in the relative weightings of securities

         o        differences  in  the  price  paid  for  particular   portfolio
                  holdings

         o        differences relating to certain tax matters

However,  the differences  cited do not alter the conclusion that the Funds have
substantially similar investment objectives, policies and strategies.

The chart below shows performance  information derived from historical composite
performance  of the public  mutual funds.  The inception  date for the composite
shown is October 1991.

The Growth & Income Composite  includes the Janus Growth & Income Fund and Janus
Aspen Series Growth & Income Fund for which Janus Capital  Corporation serves as
investment advisor.  The composite  performance was calculated  according to the
requirements of the Association  for Investment  Management and Research.  These
requirements   differ  from  those  required  by  the  Securities  and  Exchange
Commission.  Composite  performance  is  presented  net of all fees and reflects
reinvestment of dividends and capital  gains.The fees deducted are less than the
fees charged by the Series. If the expenses of the Series had been deducted, the
performance results would have been lower. As of December 31, 1999, the Growth &
Income  Composite had assets of $7,583.6  million,  which  represented  3.04% of
total assets under  management.  Accounts  enter the composite  upon their first
full quarter under management. The percentage of total assets managed is defined
as composite assets as a percentage of the total assets managed including mutual
fund  company  accounts  under  management.  Performance  figures are based upon
historical  information  and do  not  guarantee  future  results.  Please  see a
prospectus  for more complete  information  regarding  the Funds,  including the
expenses  associated with each portfolio.  In addition,  the manager responsible
for the historical  performance record of the composite from inception to August
of 1997 is no longer with the firm.  David Corkins is now the Portfolio  Manager
for all  Growth & Income  Products.  No  changes  were made  with  regard to the
investment  philosophy  or  process  of the Funds.  Prospective  clients  should
recognize the limitations  inherent in composites,  and consider all information
presented by Janus regarding its investment management capabilities. The S&P 500
is an  unmanaged  index of common  stock  prices and  includes  reinvestment  of
dividends and capital  gains.  They have been taken from  published  sources and
have not been audited.  Composition of each separately managed account portfolio
may differ significantly from securities in the corresponding benchmark indices.

A Series'  performance  may be  affected by risks  specific to certain  types of
investments, such as foreign securities, derivative investments,  non-investment
grade  debt  securities,  initial  public  offerings  (IPOs) or  companies  with
relatively small market  capitalizations.  IPOs and other investment  techniques
may have  magnified  performance  impact on a Series with a small asset base.  A
Series may not experience similar performance as its assets grow.

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series. The Series may invest in "special situations" from time
to time. A special situation arises when, in the opinion of the sub-adviser, the
securities of a particular issuer will be recognized and appreciate in value due
to a specific  development  with respect to that issuer.  Developments  creating
special  situations  might include,  among others,  a new product or process,  a
technological breakthrough, a management change or other extraordinary corporate
event, or differences in market supply of and demand for the security.Investment
in special situations may carry an additional risk of loss in the event that the
anticipated  development  does  not  occur  or does  not  attract  the  expected
attention.  The impact of this strategy on the Series will depend on the Series'
size and the extent of its  holdings of special  situation  issuers  relative to
total net assets.

The Series may use derivative instruments,  such as futures contracts,  options,
and forward currency  contracts,  for hedging or as a means of enhancing return.
These  instruments are subject to transaction  costs and certain risks,  such as
unanticipated  changes in interest rates,  securities prices and global currency
markets.

The  Series  may  invest  in  high-yield,  high-risk,  fixed-income  securities,
commonly known as "junk bonds." These are corporate debt securities rated BBB or
lower by S&P or Baa or lower by  Moody's,  or unrated  securities  deemed by the
sub-adviser  to be  on  comparable  quality.  Lower-rated  securities  generally
involve a higher risk of default than higher-rated ones.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

The  Sub-Adviser  and Portfolio  Management.  The  sub-adviser  to the JNL/Janus
Growth & Income  Series  is Janus  Capital  Corporation  (Janus  Capital),  with
principal offices at 100 Fillmore Street, Denver,  Colorado 80206. Janus Capital
providesinvestment  advisory  services to mutual  funds and other  institutional
accounts.

David  Corkins is  Portfolio  Manager of the  Series.  He is also the  portfolio
manager and Executive  Vice  President of Janus Growth and Income Fund and Janus
Aspen  Growth and Income  Portfolio.  He also manages  separate  accounts in the
LargeCap Growth and Diversified  Growth  disciplines.  Prior to joining Janus in
1995, Mr. Corkins was Chief Financial Officer of Chase U.S.  Consumer  Services,
Inc., a Chase  Manhattan  mortgage  business.  While at Chase,  Mr. Corkins also
worked in consumer  credit and  mortgage  issuance  and  analysis.  Mr.  Corkins
graduated cum laude from Dartmouth  College with a bachelor's  degree in English
and  Russian,  and  earned  an M.B.A.  in  finance  with  honors  from  Columbia
University. He has nine years of professional investment experience.

JNL/PIMCO Total Return Bond Series

Investment  Objective.  The investment  objective of the JNL/PIMCO  Total Return
Bond Series is to realize maximum total return, consistent with the preservation
of capital and prudent investment management.

Principal Investment Strategies. The Series attempts to achieve its objective by
investing primarily in a diversified portfolio of investment-grade  fixed-income
securities of U.S. and foreign issuers such as government,  corporate, mortgage-
and other  asset-backed  securities  and cash  equivalents.  At least 65% of its
total assets will be invested,  under normal market  conditions in  fixed-income
securities.

The average duration of the Series typically ranges between three and six years,
although the maturities of the securities it holds may vary. For example, with a
duration of 5 years, there will be a 5% change in the value of the Series with a
1% movement in interest rates. The Series' foreign investments will primarily be
in securities of issuers based in developed countries, although it may invest in
securities of issuers in emerging market countries. A significant portion of the
Series' foreign  holdings may be denominated in foreign  currencies.  The Series
may buy and sell foreign currency and foreign currency contracts,  and invest in
options, futures contracts, swap agreements, and other indexed instruments.  The
Series  may  enter  into a series of  purchase  or sale  contracts  or use other
investment  techniques to obtain market  exposure or to hedge against changes in
foreign currency exchange rates, interest rates or securities prices.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series invests in securities of U.S.
                  and foreign issuers,  it is subject to market risk. For bonds,
                  market risk generally  reflects  credit risk and interest rate
                  risk.  Credit  risk is the actual or  perceived  risk that the
                  issuer of the bond  will not pay the  interest  and  principal
                  payments  when  due.  Bond  value  typically  declines  if the
                  issuer's  credit quality  deteriorates.  Interest rate risk is
                  the risk that interest rates will rise and the value of bonds,
                  including  those held by the Series,  will fall. A broad-based
                  market drop may also cause a bond's price to fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.  To the extent that
                  the Series  invests in bonds  issued by a foreign  government,
                  the Series may have  limited  legal  recourse  in the event of
                  default.   Political   conditions,   especially   a  country's
                  willingness  to meet the  terms of its debt  obligations,  can
                  create special risks.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

         o        Derivatives risk. Investing in derivative instruments, such as
                  options,   futures  contracts,   forward  currency  contracts,
                  indexed  securities  and  asset-backed  securities,   involves
                  special risks. The Series  sub-adviser must correctly  predict
                  price  movements,  during  the  life of a  derivative,  of the
                  underlying  asset in order to realize the desired results from
                  the investment. The value of derivatives may rise or fall more
                  rapidly  than  other  investments,   which  may  increase  the
                  volatility of the Series depending on the nature and extent of
                  the derivatives in the Series'  portfolio.  If the sub-adviser
                  uses  derivatives  in  attempting  to  manage or  "hedge"  the
                  overall  risk of the  portfolio,  the  strategy  might  not be
                  successful,  for  example,  due to changes in the value of the
                  derivatives  that do not correlate with price movements in the
                  rest of the portfolio.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series.  The Series seeks to consistently add value relative to
the Lehman  Brothers  Aggregate Bond Index,  while keeping risk equal to or less
than that  index.  In managing  the  Series,  the  sub-adviser  generally  makes
investment  decisions  based on its view of  longer-term  (three- to  five-year)
trends and non-economic factors that may affect interest rates, while seeking to
maintain a portfolio  duration  that  approximates  that of the Lehman  Brothers
Aggregate Bond Index.

The  Series may invest in a wide  variety  of taxable  fixed-income  securities,
including  convertible  securities,  fixed-  and  floating-rate  loans  and loan
participations.  The Series may also invest in  repurchase  agreements,  reverse
repurchase agreements, and dollar rolls. The Series may invest all of its assets
in  derivative  instruments,   such  as  options,   futures  contracts  or  swap
agreements.  The  Series may  invest  all of its  assets in  mortgage-  or other
asset-backed securities, zero coupon bonds or strips.

The Series may invest in when-issued  and delayed  delivery  securities.  Actual
payment for and delivery of such  securities does not take place until some time
in the future, i.e., beyond normal settlement.  The purchase of these securities
will result in a loss if their value declines prior to the settlement date. This
could occur, for example, if interest rates increase prior to settlement.

The  Series  may  invest  in  high-yield,  high-risk,  fixed-income  securities,
commonly known as "junk bonds." These are corporate debt securities rated BBB or
lower by S&P or Baa or lower by  Moody's,  or unrated  securities  deemed by the
sub-adviser  to be  of  comparable  quality.  Lower-rated  securities  generally
involve a higher risk of default than higher-rated ones.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

The Sub-Adviser and Portfolio Management. The sub-adviser to the JNL/PIMCO Total
Return Bond Series is Pacific Investment Management Company (PIMCO),  located at
840 Newport Center Drive,  Suite 300, Newport Beach,  California 92660. PIMCO is

JNL/Putnam Growth Series

Investment  Objective.  The investment objective of the JNL/Putnam Growth Series
is long-term capital growth.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  primarily  in a  diversified  portfolio  of common stock of domestic,
large-capitalization companies. However, the Series may also invest in preferred
stocks,  bonds,  convertible  preferred stock and convertible  debentures if the
sub-adviser believes that they offer the potential for capital appreciation. The
Series may invest a portion of its assets in foreign securities.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series invests in stocks of U.S. and
                  foreign  companies,  it is subject to stock market risk. Stock
                  prices typically fluctuate more than the values of other types
                  of  securities,  typically  in  response  to  changes  in  the
                  particular company's financial condition and factors affecting
                  the  market  in   general.   For   example,   unfavorable   or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those  held by the  Series,  will  fall.  A
                  broad-based  market  drop may also  cause a  stock's  price to
                  fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Growth investing risk.  Growth companies usually invest a high
                  portion  of  earnings  in their  businesses,  and may lack the
                  dividends of value stocks that can cushion prices in a falling
                  market.  Also,  earnings  disappointments  often lead to sharp
                  declines  in prices  because  investors  buy growth  stocks in
                  anticipation of superior earnings growth.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

         o        Derivatives risk. Investing in derivative instruments, such as
                  options,   futures  contracts,   forward  currency  contracts,
                  indexed  securities  and  asset-backed  securities,   involves
                  special risks. The Series  sub-adviser must correctly  predict
                  price  movements,  during  the  life of a  derivative,  of the
                  underlying  asset in order to realize the desired results from
                  the investment. The value of derivatives may rise or fall more
                  rapidly  than  other  investments,   which  may  increase  the
                  volatility of the Series depending on the nature and extent of
                  the derivatives in the Series'  portfolio.  If the sub-adviser
                  uses  derivatives  in  attempting  to  manage or  "hedge"  the
                  overall  risk of the  portfolio,  the  strategy  might  not be
                  successful,  for  example,  due to changes in the value of the
                  derivatives  that do not correlate with price movements in the
                  rest of the portfolio.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year. The table shows the Series' assume reinvestment of
dividends and  distributions.  The Series'  returns shown in the chart and table
below do not  reflect the  deduction  of any  charges  that are imposed  under a
variable insurance contract.  Those charges, which are described in the variable
insurance  prospectus,  will reduce the Series' performance.  As with all mutual
funds, the Series' past  performance  does not necessarily  indicate how it will
perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series.  The Series may invest any amount or  proportion of its
assets in any class or type of  security  believed by the  sub-adviser  to offer
potential for capital appreciation over both the intermediate and long term.

The Series may use derivative  instruments,  such as financial futures contracts
and options,  for hedging and risk management.  These instruments are subject to
transaction costs and certain risks,  such as unanticipated  changes in interest
rates, securities prices and global currency markets.

For temporary,  defensive purposes, when the sub-adviser believes other types of
investments are advantageous on the basis both of risk and protection of capital
values,  the  Series  may  invest in  fixed-income  securities  with or  without
warrants or conversion  features and may retain cash, or invest up to all of its
assets in cash equivalents. Taking a defensive position may reduce the potential
for appreciation of the Series' portfolio.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

The  Sub-Adviser  and Portfolio  Management.  The  sub-adviser to the JNL/Putnam
Growth Series is Putnam Investment  Management,  Inc.  (Putnam),  located at One
Post Office Square, Boston, Massachusetts 02109. Putnam has been managing mutual
funds since 1937.

The Series is  managed by the Core  Growth  Equity  team at Putnam.  The team is
headed by C. Beth Cotner,  Managing Director and Chief Investment Officer of the
Group. Ms. Cotner joined Putnam in 1995 as Senior Portfolio  Manager in the Core
Growth Equity Group.  Prior to that,  Ms. Cotner was Executive Vice President of
Kemper Financial Services.  Ms. Cotner has had responsibility for the day-to-day
management of the Series since May 1, 1997.

JNL/Putnam   International   Equity  Series  (formerly  the  T.  Rowe  Price/JNL
International Equity Investment Series)

Investment Objective.  The investment objective of the JNL/Putnam  International
Equity Series is long-term growth of capital.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing at least 65% in a diversified portfolio consisting primarily of common
stocks of non-U.S.  companies. The Series invests in foreign securities that the
sub-adviser believes offer significant potential for long-term appreciation. The
Series  normally  has at least three  countries  represented  in its  portfolio,
including both developed and emerging markets.

Putnam's Core International Equity team seeks consistent, above-average relative
returns and below-average  relative risk through a balance of country and sector
diversification and the selection of believed underpriced companies.  The team's
process relies on both top-down  macroeconomic and market analysis and bottom-up
fundamental company research.

Putnam selects stocks through a bottom up process,  using its valuation approach
to identify significantly  mispriced companies.  Its expertise is in identifying
stocks selling for less than their real or relative worth regardless of the type
of  company  (i.e.,  growth,   cyclical,   or  mature)  or  the  current  market
environment. Putnam begins by screening its international stock database of over
5,500 non-U.S.  companies to identify those companies with a positive  valuation
indicator  (price to book  relative to return on equity).  Stocks  passing  this
initial valuation screen are then subjected to a rigorous process.  The decision
to purchase a stock is based on the combined judgment of the Core  International
Equity  portfolio  managers,  and  their  decision  must  be  unanimous.  Putnam
typically visits all companies before a purchase decision is finalized.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market  risk.  Because  the Series  invests  in stocks,  it is
                  subject to stock market risk. Stock prices typically fluctuate
                  more than the values of other types of  securities,  typically
                  in response to changes in the particular  company's  financial
                  condition  and factors  affecting  the market in general.  For
                  example,    unfavorable   or   unanticipated   poor   earnings
                  performance  of the  company  may  result in a decline  in its
                  stock's price, and a broad-based  market drop may also cause a
                  stock's price to fall.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in  securities  of issuers in emerging  markets,  which
                  involves  greater risk.  Emerging market  countries  typically
                  have economic and political  systems that are less  developed,
                  and  likely to be less  stable,  than  those of more  advanced
                  countries.  Emerging  market  countries may have policies that
                  restrict investment by foreigners,  and there is a higher risk
                  of a government  taking private  property.  Low or nonexistent
                  trading  volume in securities  of issuers in emerging  markets
                  may  result in a lack of  liquidity  and in price  volatility.
                  Issuers in emerging markets typically are subject to a greater
                  degree of change in earnings and business  prospects  than are
                  companies in developed markets.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

         o        Derivatives risk. Investing in derivative instruments, such as
                  options,   futures  contracts,   forward  currency  contracts,
                  indexed  securities  and  asset-backed  securities,   involves
                  special risks. The Series  sub-adviser must correctly  predict
                  price  movements,  during  the  life of a  derivative,  of the
                  underlying  asset in order to realize the desired results from
                  the investment. The value of derivatives may rise or fall more
                  rapidly  than  other  investments,   which  may  increase  the
                  volatility of the Series depending on the nature and extent of
                  the derivatives in the Series'  portfolio.  If the sub-adviser
                  uses  derivatives  in  attempting  to  manage or  "hedge"  the
                  overall  risk of the  portfolio,  the  strategy  might  not be
                  successful,  for  example,  due to changes in the value of the
                  derivatives  that do not correlate with price movements in the
                  rest of the portfolio.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

As of the effective date of this Prospectus,  Putnam Investment Management, Inc.
has replaced Rowe-Price Fleming  International,  Inc. as the sub-adviser for the
Series.  Therefore, the performance information shown below is not indicative in
any manner of how the Series will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

<PAGE>
JNL/Putnam Midcap Growth Series

Investment  Objective.  The investment objective of the JNL/Putnam Midcap Growth
Series is capital appreciation.

Principal Investment  Strategies.  The Series invests mainly in common stocks of
U.S. companies with a focus on growth stocks which are stocks whose earnings the
sub-adviser  believes  are likely to grow  faster  than the  economy as a whole.
Growth stocks typically trade at higher multiples of current earnings than other
stocks.  Therefore, the values of growth stocks may be more sensitive to changes
in current or expected earnings than the values of other stocks.

Growth stocks are issued by companies  whose earnings the  sub-adviser  believes
are likely to grow  faster  than the  economy as a whole.  Growth in a company's
earnings may lead to an increase in the price of its stock.  The Series  invests
mainly in mid-cap companies.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market  risk.   Because  the  Series   invests  in  stocks  of
                  companies,  it is subject to stock market  risk.  Stock prices
                  typically  fluctuate  more than the  values of other  types of
                  securities, typically in response to changes in the particular
                  company's financial condition and factors affecting the market
                  in general.  For example,  unfavorable or  unanticipated  poor
                  earnings performance of the company may result in a decline in
                  its  stock's  price,  and a  broad-based  market drop may also
                  cause a stock's price to fall. Investing in small and mid-size
                  companies  generally  involves greater risks than investing in
                  larger more established ones.

         o        Growth investing risk.  Growth companies usually invest a high
                  portion  of  earnings  in their  businesses,  and may lack the
                  dividends of value stocks that can cushion prices in a falling
                  market.  Also,  earnings  disappointments  often lead to sharp
                  declines  in prices  because  investors  buy growth  stocks in
                  anticipation of superior earnings growth. There is a risk that
                  the  market as a whole  may not favor the type of  investments
                  which the Series makes.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  This Series will  commence  investment  operations on or about the
date of this Prospectus. Therefore, a bar chart and table have not been included
for this Series.

COMPARABLE PERFORMANCE

 Putnam Midcap Equity (S&P Midcap 400) Composite Returns
 As of 12/31/1999

Private Account Performance Composite

The Putnam/JNL Midcap Series has substantially  similar  investment  objectives,
policies and investment  strategies as certain Private  Accounts.  Each of these
Private  Accounts  is managed  by the Putnam  Advisory  Company  Inc.  of Putnam
Fiduciary  Trust  Company,  affiliates  of the  Sub-Adviser  which  manages  the
corresponding Series.

The  historical  performance  of a composite of these Private  Accounts is shown
below. This performance data should not be considered as an indication of future
performance of the Series. The Private Account performance figures shown below:

         o        do not  reflect  Contract  fees or charges  imposed by Jackson
                  National Life.  Investors should refer to the separate account
                  prospectus  for  information  describing the Contract fees and
                  charges. These fees and charges will have a detrimental effect
                  on Series performance.

The Series and their corresponding  Private Account are expected to hold similar
securities.  However,  their  investment  results are expected to differ for the
following reasons:

         o        differences  in  asset  size  and  cash  flow  resulting  from
                  purchases  and  redemptions  of Series  shares  may  result in
                  different security selections

         o        differences in the relative weightings of securities

         o        differences  in  the  price  paid  for  particular   portfolio
                  holdings

         o        differences relating to certain tax matters

         o        differences  in  that  Private  Accounts  are not  subject  to
                  certain investment limitations,  diversification  requirements
                  and other  restrictions  imposed by federal tax and securities
                  laws.

However,  the differences  cited do not alter the conclusion that the Funds have
substantially similar investment objectives, policies and strategies.

The chart below shows performance  information derived from historical composite
performance of Private  Accounts.  The inception date for the composite shown is
March 31, 1992.

</TABLE>

1.       Composition of Composite

         The  inception  date for the Putnam  Midcap  Equity  (S&P  Midcap  400)
         Composite  was April 1,  1992.  The  composite  is  composed  of all US
         institutional  tax-exempt accounts managed by Putnam in this investment
         style.  It does not include  performance of retail funds,  accounts for
         taxable  entities,  accounts for non-US  investors  and accounts  whose
         investment  guidelines  differ  in a  material  way from  the  standard
         guidelines established by Putnam for its Midcap Equity (S&P Midcap 400)
         accounts. Since tax exempt institutional accounts typically do not need
         to manage  subscriptions and redemptions on a daily basis,  performance
         will vary from that of a mutual fund  investing in the same  investment
         style.

         Composite  returns  reflect the  deduction  of all  expenses.  The fees
         deducted are the same as the highest fees charged by the Series.

         Accounts are included no later than the beginning of the first calendar
         quarter  following  three  months  from  the date of  funding,  and are
         excluded as of the last full  calendar  month under  management or such
         prior date Putnam  receives  notice of termination  and begins managing
         the account in a manner different from other accounts in the composite.

2.       Calculation of Composite; Index Disclosure

         The investment  performance of an individual account within a composite
         is calculated monthly using a time-weighted, rate-of-return calculation
         method. The investment performance of a composite is calculated monthly
         by summing the  size-weighted  return for that month of the  individual
         accounts  that make up the  composite  for the month in  question.  The
         investment  performance of a composite over periods longer than a month
         is calculated by linking its monthly rates of return.  The  composite's
         benchmark  is the S&P Midcap 400 Index.  Performance  calculations  for
         Putnam  accounts and  comparative  indices reflect changes in value and
         reinvestment  of all  distributions.  Putnam  portfolios  are  actively
         managed using specified strategies, while the indices are unmanaged and
         may  contain  securities   different  from  those  included  in  Putnam
         portfolios.

3.       AIMR Verification

         The Putnam Midcap  Equity (S&P Midcap 400)  Composite has been Level II
         verified by Arthur  Andersen  LLP for the  calendar  years 1993,  1994,
         1995,  1996,  and 1997.  A list of Putnam's  composites  and  auditors'
         reports is available upon request.  The AIMR  requirements  differ than
         the requirements of the Securities and Exchange Commission.

4.       Past Performance

         Past performance is not necessarily  indicative of future  performance.
No assurance can be given as to future performance.

A Series'  performance  may be  affected by risks  specific to certain  types of
investments, such as foreign securities, derivative investments,  non-investment
grade  debt  securities,  initial  public  offerings  (IPOs) or  companies  with
relatively small market  capitalizations.  IPOs and other investment  techniques
may have  magnified  performance  impact on a Series with a small asset base.  A
Series may not experience similar performance as its assets grow.

and Risks of the  Series.  The Series may also invest in  securities  of foreign
issuers which involve certain special risks. These risks include,  among others,
adverse  fluctuations in foreign  currency values as well as adverse  political,
social and  economic  developments  affecting a foreign  country.  In  addition,
foreign investing involves less publicly available information and more volatile
or less liquid  markets.  Investments in foreign  countries could be affected by
factors  not  present  in the  U.S.,  such  as  restrictions  on  receiving  the
investment  proceeds  from a foreign  country,  foreign tax laws,  and potential
difficulties  in  enforcing  contractual  obligations.  Transactions  in foreign
securities  may be subject to less  efficient  settlement  practices,  including
extended  clearance  and  settlement  periods.  Foreign  accounting  may be less
revealing  than  American  accounting  practices.   Foreign  regulation  may  be
inadequate  or  irregular.  Owning  foreign  securities  could cause the Series'
performance  to  fluctuate  more than if it held only  U.S.  securities.  To the
extent  that the Series  invests in bonds  issued by a foreign  government,  the
Series  may have  limited  legal  recourse  in the event of  default.  Political
conditions,  especially  a country's  willingness  to meet the terms of its debt
obligations, can create special risks.

The Series may buy and sell investments  relatively often, which involves higher
brokerage commissions and other expenses.

In addition to the main investment  strategies  described  above, the Series may
make other  investments,  such as investments in preferred  stocks,  convertible
securities,  debt  instruments  and  derivatives,  which may be subject to other
risks, as described in the SAI.

At times the  sub-adviser  may judge that market  conditions  make  pursuing the
Series' usual investment strategies  inconsistent with the best interests of the
Series'  shareholders.  The  sub-adviser  then may  temporarily  use alternative
strategies  that are mainly designed to limit losses.  However,  the sub-adviser
may choose not to use these  strategies  for a variety of reasons,  even in very
volatile market conditions. These strategies may cause the Series to miss out on
investment opportunities, and may prevent the Series from achieving its goal.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

JNL/Putnam Value Equity Series

Investment  Objective.  The investment  objective of the JNL/Putnam Value Equity
Series is capital growth, with income as a secondary objective.

Principal Investment  Strategies.  The Series seeks to achieve its objectives by
investing primarily in a diversified portfolio of equity securities of domestic,
large-capitalization  companies.  At  least  65% of its  total  assets  will  be
invested,  under  normal  market  conditions,  in  equity  securities.  For this
purpose,  equity securities include common stocks,  securities  convertible into
common stock and securities  with common stock  characteristics,  such as rights
and  warrants.  The Series  considers a  large-capitalization  company to be one
that,  at the time its  securities  are  acquired  by the  Series,  has a market
capitalization of $2 billion or greater.

The  JNL/Putnam  Value Equity Series invests  primarily in equity  securities of
domestic,  large-capitalization  companies.  The sub-adviser  typically  selects
companies whose stocks have distinctly  above-average dividend yields and market
prices that it believes are undervalued  relative to the normal earning power of
the company.  Under this approach, the sub-adviser seeks to identify investments
where current investor enthusiasm is low, as reflected in their valuations.  The
sub-adviser  typically  reduces the Series' exposure to a company when its stock
price approaches, in the sub-adviser's judgment, fair valuation.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market  risk.   Because  the  Series  invests  in  the  equity
                  securities  of U.S.  and foreign  companies,  it is subject to
                  stock market risk. Stock prices typically  fluctuate more than
                  the values of other types of securities, typically in response
                  to changes in the particular company's financial condition and
                  factors   affecting  the  market  in  general.   For  example,
                  unfavorable or unanticipated poor earnings  performance of the
                  company  may result in a decline in its stock's  price,  and a
                  broad-based  market  drop may also  cause a  stock's  price to
                  fall.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.

         o        Value investing risk. With a value approach, there is also the
                  risk that stocks may remain undervalued during a given period.
                  This may happen  because value stocks as a category lose favor
                  with  investors  compared  to  growth  stocks or  because  the
                  manager failed to anticipate  which stocks or industries would
                  benefit from changing market or economic conditions.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

JNL/S&P Conservative Growth Series I

Investment  Objective.  The  investment  objective  of the JNL/S&P  Conservative
Growth Series I is capital growth and current income.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  in a  diversified  group of other  Series  of the  Trust  (Underlying
Series). The Underlying Series in which the JNL/S&P Conservative Growth Series I
may  invest  are  the  JNL/Alger  Growth  Series,  JNL/Alliance  Growth  Series,
JNL/Eagle  Core Equity  Series,  JNL/Eagle  SmallCap  Equity  Series,  JNL/Janus
Aggressive Growth Series,  JNL/Janus  Balanced Series,  JNL/Janus Capital Growth
Series, JNL/Janus Global Equities Series,  JNL/Putnam Growth Series,  JNL/Putnam
International Equity Series,  JNL/Putnam Value Equity Series,  JNL/Putnam Midcap
Growth Series, PPM America/JNL  Balanced Series, PPM America/JNL High Yield Bond
Series, PPM America/JNL Money Market Series,  Salomon  Brothers/JNL  Global Bond
Series,  Salomon  Brothers/JNL  U.S.  Government & Quality Bond Series,  T. Rowe
Price/JNL  Established  Growth Series,  T. Rowe Price/JNL Mid-Cap Growth Series,
and T. Rowe Price/JNL Value Series.

The Series seeks to achieve capital growth through its investments in Underlying
Series that invest primarily in equity securities. These investments may include
Series that  invest in stocks of large  established  companies  as well as those
that invest in stocks of smaller companies with above-average growth potential.

The Series seeks to achieve current income through its investments in Underlying
Series that invest primarily in fixed-income  securities.  These investments may
include Underlying Series that invest in foreign bonds denominated in currencies
other than U.S. dollars as well as Underlying Series that invest  exclusively in
bonds of U.S.  issuers.  The Series may invest in Underlying  Series that invest
exclusively in  investment-grade  securities,  as well as Underlying Series that
invest in high-yield, high-risk bonds.

Under normal circumstances, the Series allocates approximately 55% to 65% of its
assets to Underlying Series that invest primarily in equity  securities,  30% to
40% to Underlying Series that invest primarily in fixed-income securities and 0%
to 10% to Underlying Series that invest primarily in money market funds.  Within
these three asset  classes,  the Series  remains  flexible  with  respect to the
percentage it will allocate among Underlying Series.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and  you  could  lose  money  by  investing  in the  Series.  Since  the  Series
concentrates its investments in shares of the Underlying Series, its performance
is  directly  related  to the  ability  of the  Underlying  Series to meet their
respective investment objectives,  as well as the sub-adviser's allocation among
the  Underlying  Series.  Accordingly,  a variety of factors may  influence  the
performance of the Series, such as:

         o        Market risk.  Because the Series invests  indirectly in stocks
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information, more volatile or less liquid markets. Investments
                  in foreign  countries could be affected by factors not present
                  in the U.S.,  such as restrictions on receiving the investment
                  proceeds  from  a  foreign  country,  foreign  tax  laws,  and
                  potential  difficulties in enforcing contractual  obligations.
                  Transactions  in  foreign  securities  may be  subject to less
                  efficient settlement  practices,  including extended clearance
                  and  settlement  periods.   Foreign  accounting  may  be  less
                  revealing   than  American   accounting   practices.   Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate  more than if it held only U.S.  securities.  To the
                  extent that an Underlying  Series invests in bonds issued by a
                  foreign  government,   that  Series  may  have  limited  legal
                  recourse  in  the  event  of  default.  Political  conditions,
                  especially  a country's  willingness  to meet the terms of its
                  debt obligations, can create special risks.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging markets may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of  an  unanticipated  default,  an  Underlying  Series  would
                  experience a reduction in its income,  a decline in the market
                  value of the securities so affected and a decline in the value
                  of its  shares.  During an economic  downturn  or  substantial
                  period of rising interest rates,  highly leveraged issuers may
                  experience financial stress which could adversely affect their
                  ability to service principal and interest payment obligations,
                  to meet  projected  business  goals and to  obtain  additional
                  financing.  The market prices of  lower-rated  securities  are
                  generally   less  sensitive  to  interest  rate  changes  than
                  higher-rated  investments,   but  more  sensitive  to  adverse
                  economic or  political  changes,  or  individual  developments
                  specific  to the  issuer.  Periods of  economic  or  political
                  uncertainty and change can be expected to result in volatility
                  of prices of these securities.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S.   dollar   value  of  an   Underlying   Series'   foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

Because the Series invests  exclusively in other Series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying  investment  divisions.  The expenses shown below include both
the annual  operating  expenses for the JNL/S&P Series and the annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

JNL/S&P Moderate Growth Series I

Investment  Objective.  The investment  objective of the JNL/S&P Moderate Growth
Series I is to seek capital growth. Current income is a secondary objective.

Principal Investment  Strategies.  The Series seeks to achieve its objectives by
investing  in a  diversified  group of other  Series  of the  Trust  (Underlying
Series). The Underlying Series in which the JNL/S&P Moderate Growth Series I may
invest are the JNL/Alger Growth Series,  JNL/Alliance  Growth Series,  JNL/Eagle
Core Equity  Series,  JNL/Eagle  SmallCap  Equity Series,  JNL/Janus  Aggressive
Growth  Series,  JNL/Janus  Balanced  Series,  JNL/Janus  Capital Growth Series,
JNL/Janus  Global  Equities  Series,   JNL/Putnam   Growth  Series,   JNL/Putnam
International Equity Series,  JNL/Putnam Value Equity Series,  JNL/Putnam Midcap
Growth Series, PPM America/JNL  Balanced Series, PPM America/JNL High Yield Bond
Series, PPM America/JNL Money Market Series,  Salomon  Brothers/JNL  Global Bond
Series,  Salomon  Brothers/JNL  U.S.  Government & Quality Bond Series,  T. Rowe
Price/JNL  Established  Growth Series,  T. Rowe Price/JNL Mid-Cap Growth Series,
and T. Rowe Price/JNL Value Series.

The Series seeks to achieve capital growth through its investments in Underlying
Series that invest primarily in equity securities. These investments may include
Underlying Series that invest in stocks of large  established  companies as well
as those that invest in stocks of smaller  companies with  above-average  growth
potential.

The Series seeks to achieve current income through its investments in Underlying
Series that invest primarily in fixed-income  securities.  These investments may
include Underlying Series that invest in foreign bonds denominated in currencies
other than U.S. dollars as well as Underlying Series that invest  exclusively in
bonds of U.S.  issuers.  The Series may invest in Underlying  Series that invest
exclusively in  investment-grade  securities,  as well as Underlying Series that
invest in high-yield, high-risk bonds.

Under normal circumstances, the Series allocates approximately 70% to 80% of its
assets to Underlying  Series that invest primarily in equity  securities and 20%
to 30% to Underlying  Series that invest  primarily in fixed-income  securities.
Within these asset  classes,  the Series  remains  flexible  with respect to the
percentage it will allocate among particular Underlying Series.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and  you  could  lose  money  by  investing  in the  Series.  Since  the  Series
concentrates its investments in shares of the Underlying Series, its performance
is  directly  related  to the  ability  of the  Underlying  Series to meet their
respective investment objectives,  as well as the sub-adviser's allocation among
the  Underlying  Series.  Accordingly,  a variety of factors may  influence  its
performance, such as:

         o        Market risk.  Because the Series invests  indirectly in stocks
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate  more than if it held only U.S.  securities.  To the
                  extent that an Underlying  Series invests in bonds issued by a
                  foreign  government,   that  Series  may  have  limited  legal
                  recourse  in  the  event  of  default.  Political  conditions,
                  especially  a country's  willingness  to meet the terms of its
                  debt obligations, can create special risks.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging markets may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of  an  unanticipated  default,  an  Underlying  Series  would
                  experience a reduction in its income,  a decline in the market
                  value of the securities so affected and a decline in the value
                  of its  shares.  During an economic  downturn  or  substantial
                  period of rising interest rates,  highly leveraged issuers may
                  experience financial stress which could adversely affect their
                  ability to service principal and interest payment obligations,
                  to meet  projected  business  goals and to  obtain  additional
                  financing.  The market prices of  lower-rated  securities  are
                  generally   less  sensitive  to  interest  rate  changes  than
                  higher-rated  investments,   but  more  sensitive  to  adverse
                  economic or  political  changes,  or  individual  developments
                  specific  to the  issuer.  Periods of  economic  or  political
                  uncertainty and change can be expected to result in volatility
                  of prices of these securities.

         o        Currency risk.  The value of an Underlying  Series' shares may
                  change as a result of changes in exchange  rates  reducing the
                  value  of  the  U.S.  dollar  value  of  the  Series'  foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

Because the Series invests  exclusively in other series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying  investment  divisions.  The expenses shown below include both
the annual  operating  expenses for the JNL/S&P Series and the annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

Additional Information About theOther Investment  Strategies,  Other Investments
and Risks of the Series.  The JNL/S&P  Moderate Growth Series I asset allocation
is  expected  to result in less risk than that  incurred  by JNL/S&P  Aggressive
Growth Series I, JNL/S&P Very Aggressive  Growth Series I, JNL/S&P Equity Growth
Series I or  JNL/S&P  Equity  Aggressive  Growth  Series  I, but more  risk than
JNL/S&P Conservative Growth Series I.

When the sub-adviser  believes that a temporary defensive position is desirable,
the  Series  may  invest up to 100% of its  assets in cash or cash  equivalents.
Doing so may reduce the potential for appreciation of the Series' portfolio.

JNL/S&P Aggressive Growth Series I

Investment Objective.  The investment objective of the JNL/S&P Aggressive Growth
Series I is capital growth.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  in a  diversified  group of other  Series  of the  Trust  (Underlying
Series).  The Underlying Series in which the JNL/S&P  Aggressive Growth Series I
may  invest  are  the  JNL/Alger  Growth  Series,  JNL/Alliance  Growth  Series,
JNL/Eagle  Core Equity  Series,  JNL/Eagle  SmallCap  Equity  Series,  JNL/Janus
Aggressive Growth Series,  JNL/Janus  Balanced Series,  JNL/Janus Capital Growth
Series, JNL/Janus Global Equities Series,  JNL/Putnam Growth Series,  JNL/Putnam
International Equity Series,  JNL/Putnam Value Equity Series,  JNL/Putnam Midcap
Growth Series, PPM America/JNL  Balanced Series, PPM America/JNL High Yield Bond
Series, PPM America/JNL Money Market Series,  Salomon  Brothers/JNL  Global Bond
Series,  Salomon  Brothers/JNL  U.S.  Government & Quality Bond Series,  T. Rowe
Price/JNL  Established  Growth Series,  T. Rowe Price/JNL Mid-Cap Growth Series,
and T. Rowe Price/JNL Value Series.

The Series seeks to achieve capital growth primarily  through its investments in
Underlying Series that invest primarily in equity securities.  These investments
may include Series that invest in stocks of large established  companies as well
as those that invest in stocks of smaller  companies with  above-average  growth
potential.

The Series seeks to achieve capital growth secondarily through its investment in
Underlying  Series that  invest  primarily  in  fixed-income  securities.  These
investments  may  include   Underlying  Series  that  invest  in  foreign  bonds
denominated in currencies other than U.S.  dollars as well as Underlying  Series
that  invest  exclusively  in bonds of U.S.  issuers.  The  Series may invest in
Underlying Series that invest  exclusively in  investment-grade  securities,  as
well as Underlying Series that invest in high-yield, high-risk bonds.

Under normal circumstances, the Series allocates approximately 85% to 95% of its
assets to Underlying Series that invest primarily in equity securities and 5% to
15% to  Underlying  Series that invest  primarily  in  fixed-income  securities.
Within these asset  classes,  the Series  remains  flexible  with respect to the
percentage it will allocate among particular Underlying Series.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and  you  could  lose  money  by  investing  in the  Series.  Since  the  Series
concentrates its investments in shares of the Underlying Series, its performance
is  directly  related  to the  ability  of the  Underlying  Series to meet their
respective investment objectives,  as well as the sub-adviser's allocation among
the  Underlying  Series.  Accordingly,  a variety of factors may  influence  its
investment performance, such as:

         o        Market risk.  Because the Series invests  indirectly in stocks
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.High-yield/high-risk  bonds. Lower-rated bonds involve
                  a higher  degree  of credit  risk,  which is the risk that the
                  issuer will not make interest or principal  payments when due.
                  In the event of an unanticipated default, an Underlying Series
                  would  experience a reduction in its income,  a decline in the
                  market  value of the  securities  so affected and a decline in
                  the  value of its  shares.  During  an  economic  downturn  or
                  substantial period of rising interest rates,  highly leveraged
                  issuers may experience  financial stress which could adversely
                  affect their ability to service principal and interest payment
                  obligations,  to meet  projected  business goals and to obtain
                  additional   financing.   The  market  prices  of  lower-rated
                  securities  are  generally  less  sensitive  to interest  rate
                  changes than higher-rated  investments,  but more sensitive to
                  adverse   economic  or  political   changes,   or   individual
                  developments  specific to the  issuer.  Periods of economic or
                  political  uncertainty and change can be expected to result in
                  volatility of prices of these securities.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate  more than if it held only U.S.  securities.  To the
                  extent that an Underlying  Series invests in bonds issued by a
                  foreign  government,  that Series may have limited recourse in
                  the  event of  default.  Political  conditions,  especially  a
                  country's   willingness   to  meet  the   terms  of  its  debt
                  obligations, can create special risks.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging markets may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        Currency risk.  The value of an Underlying  Series' shares may
                  change as a result of changes in exchange  rates  reducing the
                  value  of  the  U.S.  dollar  value  of  the  Series'  foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

Because the Series invests  exclusively in other series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying  investment  divisions.  The expenses shown below include both
the annual  operating  expenses for the JNL/S&P Series and the annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

JNL/S&P Very Aggressive Growth Series I

Investment  Objective.  The investment  objective of the JNL/S&P Very Aggressive
Growth Series I is capital growth.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  in a  diversified  group of other  Series  of the  Trust  (Underlying
Series).  The  Underlying  Series in which the JNL/S&P  Very  Aggressive  Growth
Series I may invest are the JNL/Alger Growth Series, JNL/Alliance Growth Series,
JNL/Eagle  Core Equity  Series,  JNL/Eagle  SmallCap  Equity  Series,  JNL/Janus
Aggressive Growth Series,  JNL/Janus  Balanced Series,  JNL/Janus Capital Growth
Series, JNL/Janus Global Equities Series,  JNL/Putnam Growth Series,  JNL/Putnam
International Equity Series,  JNL/Putnam Value Equity Series,  JNL/Putnam Midcap
Growth Series, PPM America/JNL  Balanced Series, PPM America/JNL High Yield Bond
Series, PPM America/JNL Money Market Series,  Salomon  Brothers/JNL  Global Bond
Series,  Salomon  Brothers/JNL  U.S.  Government & Quality Bond Series,  T. Rowe
Price/JNL  Established  Growth Series,  T. Rowe Price/JNL Mid-Cap Growth Series,
and T. Rowe Price/JNL Value Series.

The Series seeks to achieve capital growth through its investments in Underlying
Series that invest primarily in equity securities. These investments may include
Series that  invest in stocks of large  established  companies  as well as those
that invest in stocks of smaller companies with above-average growth potential.

Under  normal  circumstances,  the Series  allocates up to 100% of its assets to
Underlying Series that invest primarily in equity securities. The Series remains
flexible with respect to the percentage it will allocate among those  particular
Underlying Series that invest primarily in equity securities.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and  you  could  lose  money  by  investing  in the  Series.  Since  the  Series
concentrates its investments in shares of the Underlying Series, its performance
is  directly  related  to the  ability  of the  Underlying  Series to meet their
respective investment objectives,  as well as the sub-adviser's allocation among
the  Underlying  Series.  Accordingly,  a variety of factors may  influence  its
investment performance, such as:

         o        Market risk.  Because the Series invests  indirectly in stocks
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate  more than if it held only U.S.  securities.  To the
                  extent that an Underlying  Series invests in bonds issued by a
                  foreign  government,   that  Series  may  have  limited  legal
                  recourse  in  the  event  of  default.  Political  conditions,
                  especially  a country's  willingness  to meet the terms of its
                  debt obligations, can create special risks.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging markets may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of an  unanticipated  default,  a Series  would  experience  a
                  reduction in its income,  a decline in the market value of the
                  securities  so  affected  and a  decline  in the  value of its
                  shares.  During an economic downturn or substantial  period of
                  rising interest rates, highly leveraged issuers may experience
                  financial stress which could adversely affect their ability to
                  service  principal and interest payment  obligations,  to meet
                  projected  business goals and to obtain additional  financing.
                  The market prices of lower-rated securities are generally less
                  sensitive  to  interest   rate   changes   than   higher-rated
                  investments,   but  more  sensitive  to  adverse  economic  or
                  political changes, or individual  developments specific to the
                  issuer.  Periods of  economic  or  political  uncertainty  and
                  change can be  expected to result in  volatility  of prices of
                  these securities.

         o        Currency risk.  The value of an Underlying  Series' shares may
                  change as a result of changes in exchange  rates  reducing the
                  value  of  the  U.S.  dollar  value  of  the  Series'  foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

Because the Series invests  exclusively in other series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year. The table shows the Series' average annual returns
and compares them to a broad based index since these shares were first  offered.
Both the chart and the table assume reinvestment of dividends and distributions.
The  Series'  returns  shown in the  chart and table  below do not  reflect  the
deduction of any charges that are imposed under a variable  insurance  contract.
Those charges,  which are described in the variable insurance  prospectus,  will
reduce the Series'  performance.  As with all mutual  funds,  the  Series'  past
performance does not necessarily indicate how it will perform in the future.

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying  investment  divisions.  The expenses shown below include both
the annual  operating  expenses for the JNL/S&P Series and the annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

         JNL/S&P Very Aggressive Growth Series I.......................  1.18%

Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate  more than if it held only U.S.  securities.  To the
                  extent that an Underlying  Series invests in bonds issued by a
                  foreign  government,   that  Series  may  have  limited  legal
                  recourse  in  the  event  of  default.  Political  conditions,
                  especially  a country's  willingness  to meet the terms of its
                  debt obligations, can create special risks.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging markets may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of an  unanticipated  default,  a Series  would  experience  a
                  reduction in its income,  a decline in the market value of the
                  securities  so  affected  and a  decline  in the  value of its
                  shares.  During an economic downturn or substantial  period of
                  rising interest rates, highly leveraged issuers may experience
                  financial stress which could adversely affect their ability to
                  service  principal and interest payment  obligations,  to meet
                  projected  business goals and to obtain additional  financing.
                  The market prices of lower-rated securities are generally less
                  sensitive  to  interest   rate   changes   than   higher-rated
                  investments,   but  more  sensitive  to  adverse  economic  or
                  political changes, or individual  developments specific to the
                  issuer.  Periods of  economic  or  political  uncertainty  and
                  change can be  expected to result in  volatility  of prices of
                  these securities.

         o        Currency risk.  The value of an Underlying  Series' shares may
                  change as a result of changes in exchange  rates  reducing the
                  value  of  the  U.S.  dollar  value  of  the  Series'  foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

Because the Series invests  exclusively in other series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the annual  returns and  compares
them to a broad  based index since  these  shares were first  offered.  Both the
chart and the table assume  reinvestment  of dividends  and  distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying  investment  divisions.  The expenses shown below include both
the annual  operating  expenses for the JNL/S&P Series and the annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series.  The JNL/S&P Equity Growth Series I asset allocation is
expected  to result in more risk than  that  incurred  by  JNL/S&P  Conservative
Growth Series I, JNL/S&P Moderate Growth Series I and JNL/S&P  Aggressive Growth
Series  I, but less risk  than  JNL/S&P  Equity  Aggressive  Growth  Series I or
JNL/S&P Very Aggressive  Growth Series I. When the  sub-adviser  believes that a
temporary  defensive position is desirable,  the Series may invest up to 100% of
its assets in cash, cash equivalents or Underlying  Series that invest primarily
in fixed-income securities. Taking a defensive position may reduce the potential
for appreciation of the Series' portfolio.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

JNL/S&P Equity Aggressive Growth Series I

Investment Objective.  The investment objective of the JNL/S&P Equity Aggressive
Growth Series I is capital growth.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  in a  diversified  group of other  Series  of the  Trust  (Underlying
Series).  The Underlying Series in which JNL/S&P Equity Aggressive Growth Series
I may  invest are the  JNL/Alger  Growth  Series,  JNL/Alliance  Growth  Series,
JNL/Eagle  Core Equity  Series,  JNL/Eagle  SmallCap  Equity  Series,  JNL/Janus
Aggressive Growth Series,  JNL/Janus  Balanced Series,  JNL/Janus Capital Growth
Series, JNL/Janus Global Equities Series,  JNL/Putnam Growth Series,  JNL/Putnam
International Equity Series,  JNL/Putnam Value Equity Series,  JNL/Putnam Midcap
Growth Series, PPM America/JNL  Balanced Series, PPM America/JNL High Yield Bond
Series, PPM America/JNL Money Market Series,  Salomon  Brothers/JNL  Global Bond
Series,  Salomon  Brothers/JNL  U.S.  Government & Quality Bond Series,  T. Rowe
Price/JNL  Established  Growth Series,  T. Rowe Price/JNL Mid-Cap Growth Series,
and T. Rowe Price/JNL Value Series.

The Series seeks to achieve capital growth through its investments in Underlying
Series that invest primarily in equity securities. These investments may include
Series that  invest in stocks of large  established  companies  as well as those
that invest in stocks of smaller companies with above-average growth potential.

Under  normal  circumstances,  the  Series  allocates  100%  of  its  assets  to
Underlying Series that invest primarily in equity securities. The Series remains
flexible with respect to the percentage it will allocate among those  particular
Underlying Series that invest primarily in equity securities.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and  you  could  lose  money  by  investing  in the  Series.  Since  the  Series
concentrates its investments in shares of the Underlying Series, its performance
is  directly  related  to the  ability  of the  Underlying  Series to meet their
respective investment objectives,  as well as the sub-adviser's allocation among
the  Underlying  Series.  Accordingly,  a variety of factors may  influence  its
investment performance, such as:

         o        Market risk.  Because the Series invests  indirectly in stocks
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate  more than if it held only U.S.  securities.  To the
                  extent that an Underlying  Series invests in bonds issued by a
                  foreign  government,   that  Series  may  have  limited  legal
                  recourse  in  the  event  of  default.  Political  conditions,
                  especially  a country's  willingness  to meet the terms of its
                  debt obligations, can create special risks.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging  market may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of an  unanticipated  default,  a Series  would  experience  a
                  reduction in its income,  a decline in the market value of the
                  securities  so  affected  and a  decline  in the  value of its
                  shares.  During an economic downturn or substantial  period of
                  rising interest rates, highly leveraged issuers may experience
                  financial stress which could adversely affect their ability to
                  service  principal and interest payment  obligations,  to meet
                  projected  business goals and to obtain additional  financing.
                  The market prices of lower-rated securities are generally less
                  sensitive  to  interest   rate   changes   than   higher-rated
                  investments,   but  more  sensitive  to  adverse  economic  or
                  political changes, or individual  developments specific to the
                  issuer.  Periods of  economic  or  political  uncertainty  and
                  change can be  expected to result in  volatility  of prices of
                  these securities.

         o        Currency risk.  The value of an Underlying  Series' shares may
                  change as a result of changes in exchange  rates  reducing the
                  value  of  the  U.S.  dollar  value  of  the  Series'  foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

Because the Series invests  exclusively in other series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying  investment  divisions.  The expenses shown below include both
the annual  operating  expenses for the JNL/S&P Series and the annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series.  The JNL/S&P  Equity  Aggressive  Growth Series I asset
allocation  is  expected  to result in more risk than that  incurred  by JNL/S&P
Conservative  Growth  Series  I,  JNL/S&P  Moderate  Growth  Series  I,  JNL/S&P
Aggressive Growth Series I or JNL/S&P Equity Growth Series I, but less risk than
JNL/S&P Very Aggressive Growth Series I.

When the sub-adviser  believes that a temporary defensive position is desirable,
the  Series may invest up to 100% of its  assets in cash,  cash  equivalents  or
Underlying  Series that invest  primarily in fixed-income  securities.  Taking a
defensive  position may reduce the  potential  for  appreciation  of the Series'
portfolio.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

The Sub-Adviser and Portfolio Management.  The sub-adviser to the JNL/S&P Equity
Aggressive  Growth Series I is Standard & Poor's Investment  Advisory  Services,
Inc.  (SPIAS),  located at 25  Broadway,  New York,  New York  10004.  SPIAS was

JNL/S&P Conservative Growth Series II

Investment  Objective.  The  investment  objective  of the JNL/S&P  Conservative
Growth Series II is capital growth and current income.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  in a  diversified  group of other  Series  of the  Trust  (Underlying
Series).  The Underlying Series in which the JNL/S&P  Conservative Growth Series
II may invest are the JNL/Alliance Growth Series,  JNL/J.P. Morgan International
& Emerging Markets Series,  JNL/Janus Aggressive Growth Series, JNL/Janus Global
Equities Series,  JNL/Janus Growth & Income Series,  JNL/PIMCO Total Return Bond
Series,  JNL/Putnam  Growth  Series,  JNL/Putnam  International  Equity  Series,
JNL/Putnam Value Equity Series,  JNL/Putnam Midcap Growth Series, Lazard/JNL Mid
Cap Value Series,  Lazard/JNL  Small Cap Value  Series,  PPM  America/JNL  Money
Market Series, Salomon Brothers/JNL Balanced Series, Salomon Brothers/JNL Global
Bond Series,  Salomon Brothers/JNL High Yield Bond Series, and T. Rowe Price/JNL
Mid-Cap Growth Series.

The Series seeks to achieve capital growth through its investments in Underlying
Series that invest primarily in equity securities. These investments may include
Underlying Series that invest in stocks of large  established  companies as well
as those that invest in stocks of smaller  companies with  above-average  growth
potential.

The Series seeks to achieve current income through its investments in Underlying
Series that invest primarily in fixed-income  securities.  These investments may
include Underlying Series that invest in foreign bonds denominated in currencies
other than U.S. dollars as well as Underlying Series that invest  exclusively in
bonds of U.S.  issuers.  The Series may invest in Underlying  Series that invest
exclusively in  investment-grade  securities,  as well as Underlying Series that
invest in high-yield, high-risk bonds.

Under normal circumstances, the Series allocates approximately 60% to 70% of its
assets to Underlying  Series that invest primarily in equity  securities and 30%
to 40% to Underlying  Series that invest  primarily in fixed-income  securities.
Within these asset  classes,  the Series  remains  flexible  with respect to the
percentage it will allocate among particular Underlying Series.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and  you  could  lose  money  by  investing  in the  Series.  Since  the  Series
concentrates its investments in shares of the Underlying Series, its performance
is  directly  related  to the  ability  of the  Underlying  Series to meet their
respective investment objectives,  as well as the sub-adviser's allocation among
the  Underlying  Series.  Accordingly,  a variety of factors may  influence  its
performance, such as:

         o        Market risk.  Because the Series invests  indirectly in stocks
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate  more than if it held only U.S.  securities.  To the
                  extent that an Underlying  Series invests in bonds issued by a
                  foreign  government,   that  Series  may  have  limited  legal
                  recourse  in  the  event  of  default.  Political  conditions,
                  especially  a country's  willingness  to meet the terms of its
                  debt obligations, can create special risks.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging markets may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of  an  unanticipated  default,  an  Underlying  Series  would
                  experience a reduction in its income,  a decline in the market
                  value of the securities so affected and a decline in the value
                  of its  shares.  During an economic  downturn  or  substantial
                  period of rising interest rates,  highly leveraged issuers may
                  experience financial stress which could adversely affect their
                  ability to service principal and interest payment obligations,
                  to meet  projected  business  goals and to  obtain  additional
                  financing.  The market prices of  lower-rated  securities  are
                  generally   less  sensitive  to  interest  rate  changes  than
                  higher-rated  investments,   but  more  sensitive  to  adverse
                  economic or  political  changes,  or  individual  developments
                  specific  to the  issuer.  Periods of  economic  or  political
                  uncertainty and change can be expected to result in volatility
                  of prices of these securities.

         o        Currency risk.  The value of an Underlying  Series' shares may
                  change as a result of changes in exchange  rates  reducing the
                  value  of  the  U.S.  dollar  value  of  the  Series'  foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

Because the Series invests  exclusively in other series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
series.

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying  investment  divisions.  The expenses shown below include both
the annual  operating  expenses for the JNL/S&P Series and the annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

JNL/S&P Moderate Growth Series II

Investment  Objective.  The investment  objective of the JNL/S&P Moderate Growth
Series II is capital growth. Current income is a secondary objective.

Principal  Investment  Strategies.  The Series  seeks to achieve its  investment
objectives  by  investing  in a  diversified  group of other Series of the Trust
(Underlying  Series). The Underlying Series in which the JNL/S&P Moderate Growth
Series  II may  invest  are the  JNL/Alliance  Growth  Series,  JNL/J.P.  Morgan
International & Emerging  Markets Series,  JNL/Janus  Aggressive  Growth Series,
JNL/Janus  Global Equities Series,  JNL/Janus Growth & Income Series,  JNL/PIMCO
Total Return Bond Series,  JNL/Putnam  Growth Series,  JNL/Putnam  International
Equity Series,  JNL/Putnam Value Equity Series, JNL/Putnam Midcap Growth Series,
Lazard/JNL  Mid Cap  Value  Series,  Lazard/JNL  Small  Cap  Value  Series,  PPM
America/JNL Money Market Series,  Salomon Brothers/JNL Balanced Series,  Salomon
Brothers/JNL  Global Bond Series,  Salomon  Brothers/JNL High Yield Bond Series,
and T. Rowe Price/JNL Mid-Cap Growth Series.

The Series seeks to achieve capital growth through its investments in Underlying
Series that invest primarily in equity securities. These investments may include
Underlying Series that invest in stocks of large  established  companies as well
as those that invest in stocks of smaller  companies with  above-average  growth
potential.

The Series seeks to achieve current income through its investments in Underlying
Series that invest primarily in fixed-income  securities.  These investments may
include Underlying Series that invest in foreign bonds denominated in currencies
other than U.S. dollars as well as Underlying Series that invest  exclusively in
bonds of U.S.  issuers.  The Series may invest in Underlying  Series that invest
exclusively in  investment-grade  securities,  as well as Underlying Series that
invest in high-yield, high-risk bonds.

Under normal circumstances, the Series allocates approximately 70% to 80% of its
assets to Underlying  Series that invest primarily in equity  securities and 20%
to 30% to Underlying  Series that invest  primarily in fixed-income  securities.
Within these asset  classes,  the Series  remains  flexible  with respect to the
percentage it will allocate among particular Underlying Series.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and  you  could  lose  money  by  investing  in the  Series.  Since  the  Series
concentrates its investments in shares of the Underlying Series, its performance
is  directly  related  to the  ability  of the  Underlying  Series to meet their
respective investment objectives,  as well as the sub-adviser's allocation among
the  Underlying  Series.  Accordingly,  a variety of factors may  influence  its
performance, such as:

         o        Market risk.  Because the Series invests  indirectly in stocks
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate  more than if it held only U.S.  securities.  To the
                  extent that an Underlying  Series invests in bonds issued by a
                  foreign  government,   that  Series  may  have  limited  legal
                  recourse  in  the  event  of  default.  Political  conditions,
                  especially  a country's  willingness  to meet the terms of its
                  debt obligations, can create special risks.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging markets may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of  an  unanticipated  default,  an  Underlying  Series  would
                  experience a reduction in its income,  a decline in the market
                  value of the securities so affected and a decline in the value
                  of its  shares.  During an economic  downturn  or  substantial
                  period of rising interest rates,  highly leveraged issuers may
                  experience financial stress which could adversely affect their
                  ability to service principal and interest payment obligations,
                  to meet  projected  business  goals and to  obtain  additional
                  financing.  The market prices of  lower-rated  securities  are
                  generally   less  sensitive  to  interest  rate  changes  than
                  higher-rated  investments,   but  more  sensitive  to  adverse
                  economic or  political  changes,  or  individual  developments
                  specific  to the  issuer.  Periods of  economic  or  political
                  uncertainty and change can be expected to result in volatility
                  of prices of these securities.

         o        Currency risk.  The value of an Underlying  Series' shares may
                  change as a result of changes in exchange  rates  reducing the
                  value  of  the  U.S.  dollar  value  of  the  Series'  foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified  funds may invest in fewer asset, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

Because the Series invests  exclusively in other series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying  investment  divisions.  The expenses shown below include both
the annual  operating  expenses for the JNL/S&P Series and the annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series.  The JNL/S&P Moderate Growth Series II asset allocation
is  expected  to result in less risk than that  incurred  by JNL/S&P  Aggressive
Growth  Series II,  JNL/S&P Very  Aggressive  Growth Series II,  JNL/S&P  Equity
Growth Series II or JNL/S&P  Equity  Aggressive  Growth Series II, but more risk
than JNL/S&P Conservative Growth Series II.

When the sub-adviser  believes that a temporary defensive position is desirable,
the  Series  may  invest up to 100% of its  assets in cash or cash  equivalents.
Doing so may reduce the potential for appreciation of the Series' portfolio.

JNL/S&P Aggressive Growth Series II

Investment Objective.  The investment objective of the JNL/S&P Aggressive Growth
Series II is capital growth.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  in a  diversified  group of other  Series  of the  Trust  (Underlying
Series).  The Underlying Series in which the JNL/S&P Aggressive Growth Series II
may invest are the JNL/Alliance Growth Series,  JNL/J.P.  Morgan International &
Emerging Market Series,  JNL/Janus  Aggressive  Growth Series,  JNL/Janus Global
Equities Series,  JNL/Janus Growth & Income Series,  JNL/PIMCO Total Return Bond
Series,  JNL/Putnam  Growth  Series,  JNL/Putnam  International  Equity  Series,
JNL/Putnam Value Equity Series,  JNL/Putnam Midcap Growth Series, Lazard/JNL Mid
Cap Value Series,  Lazard/JNL  Small Cap Value  Series,  PPM  America/JNL  Money
Market Series, Salomon Brothers/JNL Balanced Series, Salomon Brothers/JNL Global
Bond Series,  Salomon Brothers/JNL High Yield Bond Series, and T. Rowe Price/JNL
Mid-Cap Growth Series.

The Series seeks to achieve capital growth primarily  through its investments in
Underlying Series that invest primarily in equity securities.  These investments
may include Series that invest in stocks of large established  companies as well
as those that invest in stocks of smaller  companies with  above-average  growth
potential.

The Series seeks to achieve capital growth secondarily through its investment in
Underlying  Series that  invest  primarily  in  fixed-income  securities.  These
investments  may  include   Underlying  Series  that  invest  in  foreign  bonds
denominated in currencies other than U.S.  dollars as well as Underlying  Series
that  invest  exclusively  in bonds of U.S.  issuers.  The  Series may invest in
Underlying Series that invest  exclusively in  investment-grade  securities,  as
well as Underlying Series that invest in high-yield, high-risk bonds.

Under normal circumstances, the Series allocates approximately 85% to 95% of its
assets to Underlying Series that invest primarily in equity securities and 5% to
15% to  Underlying  Series that invest  primarily  in  fixed-income  securities.
Within these asset  classes,  the Series  remains  flexible  with respect to the
percentage it will allocate among particular Underlying Series.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and  you  could  lose  money  by  investing  in the  Series.  Since  the  Series
concentrates its investments in shares of the Underlying Series, its performance
is  directly  related  to the  ability  of the  Underlying  Series to meet their
respective investment objectives,  as well as the sub-adviser's allocation among
the  Underlying  Series.  Accordingly,  a variety of factors may  influence  its
investment performance, such as:

         o        Market risk.  Because the Series invests  indirectly in stocks
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate  more than if it held only U.S.  securities.  To the
                  extent that an Underlying  Series invests in bonds issued by a
                  foreign  government,   that  Series  may  have  limited  legal
                  recourse  in  the  event  of  default.  Political  conditions,
                  especially  a country's  willingness  to meet the terms of its
                  debt obligations, can create special risks.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging markets may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of  an  unanticipated  default,  an  Underlying  Series  would
                  experience a reduction in its income,  a decline in the market
                  value of the securities so affected and a decline in the value
                  of its  shares.  During an economic  downturn  or  substantial
                  period of rising interest rates,  highly leveraged issuers may
                  experience financial stress which could adversely affect their
                  ability to service principal and interest payment obligations,
                  to meet  projected  business  goals and to  obtain  additional
                  financing.  The market prices of  lower-rated  securities  are
                  generally   less  sensitive  to  interest  rate  changes  than
                  higher-rated  investments,   but  more  sensitive  to  adverse
                  economic or  political  changes,  or  individual  developments
                  specific  to the  issuer.  Periods of  economic  or  political
                  uncertainty and change can be expected to result in volatility
                  of prices of these securities.

         o        Currency risk.  The value of an Underlying  Series' shares may
                  change as a result of changes in exchange  rates  reducing the
                  value  of  the  U.S.  dollar  value  of  the  Series'  foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

Because the Series invests  exclusively in other series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

Expenses.  The table below  shows  certain  expenses  you will incur as a Series
investor.

--------------------------------------------------------------------------------
Total Series Annual Operating Expenses                               0.20%
--------------------------------------------------------------------------------

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying  investment  divisions.  The expenses shown below include both
the annual  operating  expenses for the JNL/S&P Series and the annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

         JNL/S&P Aggressive Growth Series II...........................  1.21%

Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Additional Information About the Other Investment Strategies,  Other Investments
and  Risks  of the  Series.  The  JNL/S&P  Aggressive  Growth  Series  II  asset
allocation is expected to result in less risk than that incurred by JNL/S&P Very
Aggressive  Growth Series II,  JNL/S&P Equity Growth Series II or JNL/S&P Equity
Aggressive  Growth  Series II, but more risk than  JNL/S&P  Conservative  Growth
Series II or JNL/S&P Moderate Growth Series II.

The Series seeks to achieve capital growth through its investments in Underlying
Series that invest primarily in equity securities. These investments may include
Series that  invest in stocks of large  established  companies  as well as those
that invest in stocks of smaller companies with above-average growth potential.

Under  normal  circumstances,  the  Series  allocates  100%  of  its  assets  to
Underlying Series that invest primarily in equity securities. The Series remains
flexible with respect to the percentage it will allocate among those  particular
Underlying Series that invest primarily in equity securities.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and  you  could  lose  money  by  investing  in the  Series.  Since  the  Series
concentrates its investments in shares of the Underlying Series, its performance
is  directly  related  to the  ability  of the  Underlying  Series to meet their
respective investment objectives,  as well as the sub-adviser's allocation among
the  Underlying  Series.  Accordingly,  a variety of factors may  influence  its
investment performance, such as:

         o        Market risk.  Because the Series invests  indirectly in stocks
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate  more than if it held only U.S.  securities.  To the
                  extent that an Underlying  Series invests in bonds issued by a
                  foreign  government,   that  Series  may  have  limited  legal
                  recourse  in  the  event  of  default.  Political  conditions,
                  especially  a country's  willingness  to meet the terms of its
                  debt obligations, can create special risks.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging markets may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of an  unanticipated  default,  a Series  would  experience  a
                  reduction in its income,  a decline in the market value of the
                  securities  so  affected  and a  decline  in the  value of its
                  shares.  During an economic downturn or substantial  period of
                  rising interest rates, highly leveraged issuers may experience
                  financial stress which could adversely affect their ability to
                  service  principal and interest payment  obligations,  to meet
                  projected  business goals and to obtain additional  financing.
                  The market prices of lower-rated securities are generally less
                  sensitive  to  interest   rate   changes   than   higher-rated
                  investments,   but  more  sensitive  to  adverse  economic  or
                  political changes, or individual  developments specific to the
                  issuer.  Periods of  economic  or  political  uncertainty  and
                  change can be  expected to result in  volatility  of prices of
                  these securities.

         o        Currency risk.  The value of an Underlying  Series' shares may
                  change as a result of changes in exchange  rates  reducing the
                  value  of  the  U.S.  dollar  value  of  the  Series'  foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

Because the Series invests  exclusively in other series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying  investment  divisions.  The expenses shown below include both
the annual  operating  expenses for the JNL/S&P Series and the annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table

annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or

JNL/S&P Equity Growth Series II

Investment  Objective.  The  investment  objective of the JNL/S&P  Equity Growth
Series II is capital growth.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  in a  diversified  group of other  Series  of the  Trust  (Underlying
Series).  The Underlying Series in which the JNL/S&P Equity Growth Series II may
invest are the  JNL/Alliance  Growth Series,  JNL/J.P.  Morgan  International  &
Emerging Markets Series,  JNL/Janus  Aggressive Growth Series,  JNL/Janus Global
Equities Series,  JNL/Janus Growth & Income Series,  JNL/PIMCO Total Return Bond
Series,  JNL/Putnam  Growth  Series,  JNL/Putnam  International  Equity  Series,
JNL/Putnam Value Equity Series,  JNL/Putnam Midcap Growth Series, Lazard/JNL Mid
Cap Value Series,  Lazard/JNL  Small Cap Value  Series,  PPM  America/JNL  Money
Market Series, Salomon Brothers/JNL Balanced Series, Salomon Brothers/JNL Global
Bond Series,  Salomon Brothers/JNL High Yield Bond Series, and T. Rowe Price/JNL
Mid-Cap Growth Series.

The Series seeks to achieve capital growth through its investments in Underlying
Series that invest primarily in equity securities. These investments may include
Series that  invest in stocks of large  established  companies  as well as those
that invest in stocks of smaller companies with above-average growth potential.

Under  normal  circumstances,  the  Series  allocates  100%  of  its  assets  to
Underlying Series that invest primarily in equity securities. The Series remains
flexible with respect to the percentage it will allocate among those  particular
Underlying Series that invest primarily in equity securities.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and  you  could  lose  money  by  investing  in the  Series.  Since  the  Series
concentrates its investments in shares of the Underlying Series, its performance
is  directly  related  to the  ability  of the  Underlying  Series to meet their
respective investment objectives,  as well as the sub-adviser's allocation among
the  Underlying  Series.  Accordingly,  a variety of factors may  influence  its
investment performance, such as:

         o        Market risk.  Because the Series invests  indirectly in stocks
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate  more than if it held only U.S.  securities.  To the
                  extent that an Underlying  Series invests in bonds issued by a
                  foreign  government,   that  Series  may  have  limited  legal
                  recourse  in  the  event  of  default.  Political  conditions,
                  especially  a country's  willingness  to meet the terms of its
                  debt obligations, can create special risks.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging markets may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of an  unanticipated  default,  a Series  would  experience  a
                  reduction in its income,  a decline in the market value of the
                  securities  so  affected  and a  decline  in the  value of its
                  shares.  During an economic downturn or substantial  period of
                  rising interest rates, highly leveraged issuers may experience
                  financial stress which could adversely affect their ability to
                  service  principal and interest payment  obligations,  to meet
                  projected  business goals and to obtain additional  financing.
                  The market prices of lower-rated securities are generally less
                  sensitive  to  interest   rate   changes   than   higher-rated
                  investments,   but  more  sensitive  to  adverse  economic  or
                  political changes, or individual  developments specific to the
                  issuer.  Periods of  economic  or  political  uncertainty  and
                  change can be  expected to result in  volatility  of prices of
                  these securities.

         o        Currency risk.  The value of an Underlying  Series' shares may
                  change as a result of changes in exchange  rates  reducing the
                  value  of  the  U.S.  dollar  value  of  the  Series'  foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

Because the Series invests  exclusively in other series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying  investment  divisions.  The expenses shown below include both
the annual  operating  expenses for the JNL/S&P Series and the annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series. The JNL/S&P Equity Growth Series II asset allocation is
expected  to result in more risk than  that  incurred  by  JNL/S&P  Conservative
Growth  Series II,  JNL/S&P  Moderate  Growth  Series II and JNL/S&P  Aggressive
Growth Series II, but less risk than JNL/S&P Equity  Aggressive Growth Series II
or JNL/S&P VeryAggressive Growth Series II.

When the sub-adviser  believes that a temporary defensive position is desirable,
the  Series may invest up to 100% of its  assets in cash,  cash  equivalents  or
Underlying  Series that invest  primarily in fixed-income  securities.  Taking a
defensive  position may reduce the  potential  for  appreciation  of the Series'
portfolio.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

JNL/S&P Equity Aggressive Growth Series II

Investment Objective.  The investment objective of the JNL/S&P Equity Aggressive
Growth Series II is capital growth.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  in a  diversified  group of other  Series  of the  Trust  (Underlying
Series).  The Underlying  Series in which the JNL/S&P Equity  Aggressive  Growth
Series  II may  invest  are the  JNL/Alliance  Growth  Series,  JNL/J.P.  Morgan
International & Emerging  Markets Series,  JNL/Janus  Aggressive  Growth Series,
JNL/Janus  Global Equities Series,  JNL/Janus Growth & Income Series,  JNL/PIMCO
Total Return Bond Series,  JNL/Putnam  Growth Series,  JNL/Putnam  International
Equity Series,  JNL/Putnam Value Equity Series, JNL/Putnam Midcap Growth Series,
Lazard/JNL  Mid Cap  Value  Series,  Lazard/JNL  Small  Cap  Value  Series,  PPM
America/JNL Money Market Series,  Salomon Brothers/JNL Balanced Series,  Salomon
Brothers/JNL Global Bond Series, Salomon Brothers/JNL High Yield Bond Series and
T. Rowe Price/JNL Mid-Cap Growth Series.

The Series seeks to achieve capital growth through its investments in Underlying
Series that invest primarily in equity securities. These investments may include
Series that  invest in stocks of large  established  companies  as well as those
that invest in stocks of smaller companies with above-average growth potential.

Under  normal  circumstances,  the  Series  allocates  100%  of  its  assets  to
Underlying Series that invest primarily in equity securities. The Series remains
flexible with respect to the percentage it will allocate among those  particular
Underlying Series that invest primarily in equity securities.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and  you  could  lose  money  by  investing  in the  Series.  Since  the  Series
concentrates its investments in shares of the Underlying Series, its performance
is  directly  related  to the  ability  of the  Underlying  Series to meet their
respective investment objectives,  as well as the sub-adviser's allocation among
the  Underlying  Series.  Accordingly,  a variety of factors may  influence  its
investment performance, such as:

         o        Market risk.  Because the Series invests  indirectly in stocks
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate  more than if it held only U.S.  securities.  To the
                  extent that an Underlying  Series invests in bonds issued by a
                  foreign  government,   that  Series  may  have  limited  legal
                  recourse  in  the  event  of  default.  Political  conditions,
                  especially  a country's  willingness  to meet the terms of its
                  debt obligations, can create special risks.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging markets may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of an  unanticipated  default,  a Series  would  experience  a
                  reduction in its income,  a decline in the market value of the
                  securities  so  affected  and a  decline  in the  value of its
                  shares.  During an economic downturn or substantial  period of
                  rising interest rates, highly leveraged issuers may experience
                  financial stress which could adversely affect their ability to
                  service  principal and interest payment  obligations,  to meet
                  projected  business goals and to obtain additional  financing.
                  The market prices of lower-rated securities are generally less
                  sensitive  to  interest   rate   changes   than   higher-rated
                  investments,   but  more  sensitive  to  adverse  economic  or
                  political changes, or individual  developments specific to the
                  issuer.  Periods of  economic  or  political  uncertainty  and
                  change can be  expected to result in  volatility  of prices of
                  these securities.

         o        Currency risk.  The value of an Underlying  Series' shares may
                  change as a result of changes in exchange  rates  reducing the
                  value  of  the  U.S.  dollar  value  of  the  Series'  foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger proportions of single companies or industries. Thus,
                  the  Series may hold a smaller  number of  issuers  than if it
                  were   "diversified."  With  a  smaller  number  of  different
                  issuers,  the Series is subject to more risk than another fund
                  holding  a larger  number of  issuers,  since  changes  in the
                  financial  condition or market  status of a single  issuer may
                  cause  greater  fluctuation  in the Series'  total  return and
                  share price.

Because the Series invests  exclusively in other series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
series.

compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying  investment  divisions.  The expenses shown below include both
the annual  operating  expenses for the JNL/S&P Series and the annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series.  The JNL/S&P Equity  Aggressive  Growth Series II asset
allocation  is  expected  to result in more risk than that  incurred  by JNL/S&P
Conservative  Growth  Series II,  JNL/S&P  Moderate  Growth  Series II,  JNL/S&P
Aggressive  Growth  Series II or JNL/S&P  Equity Growth Series II, but less risk
than JNL/S&P Very Aggressive Growth Series II.

When the sub-adviser  believes that a temporary defensive position is desirable,
the  Series may invest up to 100% of its  assets in cash,  cash  equivalents  or
Underlying  Series that invest  primarily in fixed-income  securities.  Taking a
defensive  position may reduce the  potential  for  appreciation  of the Series'
portfolio.

JNL/S&P Conservative Growth Series

Investment  Objective.  The  investment  objective  of the JNL/S&P  Conservative
Growth Series is capital growth and current income.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  in a  diversified  group of other  Series  of the  Trust  (Underlying
Series).  The Underlying Series in which the JNL/S&P  Conservative Growth Series
may invest are the JNL/Alliance Growth Series,  JNL/J.P. Morgan Enhanced S&P 500
Stock Index Series,  JNL/J.P.  Morgan  International & Emerging  Markets Series,
JNL/Janus Aggressive Growth Series,  JNL/Janus Global Equities Series, JNL/Janus
Growth & Income Series, JNL/PIMCO Total Return Bond Series, Lazard/JNL Small Cap
Value Series,  Lazard/JNL  Mid Cap Value Series,  PPM  America/JNL  Money Market
Series, JNL/Putnam International Equity Series, JNL/Putnam Midcap Growth Series,
Salomon Brothers/JNL  Balanced Series,  Salomon Brothers/JNL Global Bond Series,
Salomon  Brothers/JNL  High Yield Bond  Series,  and T. Rowe  Price/JNL  Mid-Cap
Growth Series.

The Series seeks to achieve capital growth through its investments in Underlying
Series that invest primarily in equity securities. These investments may include
Underlying Series that invest in stocks of large  established  companies as well
as those that invest in stocks of smaller  companies with  above-average  growth
potential.

The Series seeks to achieve current income through its investments in Underlying
Series that invest primarily in fixed-income  securities.  These investments may
include Underlying Series that invest exclusively in bonds of U.S. corporate and
government   issuers  and   Underlying   Series  that  invest   exclusively   in
investment-grade securities.

Under normal circumstances, the Series allocates approximately 50% to 75% of its
assets to Underlying Series that invest primarily in equity  securities,  15% to
50% to Underlying Series that invest primarily in fixed-income securities and 0%
to 20% to  Underlying  Securities  that invest  primarily in money market funds.
Within these asset  classes,  the Series  remains  flexible  with respect to the
percentage it will allocate among particular Underlying Series.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and  you  could  lose  money  by  investing  in the  Series.  Since  the  Series
concentrates its investments in shares of the Underlying Series, its performance
is  directly  related  to the  ability  of the  Underlying  Series to meet their
respective investment objectives,  as well as the sub-adviser's allocation among
the  Underlying  Series.  Accordingly,  a variety of factors may  influence  its
performance, such as:

         o        Market risk.  Because the Series invests  indirectly in stocks
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate  more than if it held only U.S.  securities.  To the
                  extent that an Underlying  Series invests in bonds issued by a
                  foreign  government,   that  Series  may  have  limited  legal
                  recourse  in  the  event  of  default.  Political  conditions,
                  especially  a country's  willingness  to meet the terms of its
                  debt obligations, can create special risks.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging markets may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        Currency risk.  The value of an Underlying  Series' shares may
                  change as a result of changes in exchange  rates  reducing the
                  value  of  the  U.S.  dollar  value  of  the  Series'  foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

Because the Series invests  exclusively in other series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
series.

Performance.  The  performance  of the Series  will vary from year to year.  The
Series'  performance  figures will not reflect the deduction of any charges that
are  imposed  under a variable  insurance  contract.  Those  charges,  which are
described  in  the  variable  insurance  prospectus,  will  reduce  the  Series'
performance.  As with all mutual funds,  the Series' past  performance  does not
necessarily indicate how it will perform in the future.

Performance for the Series has not been included because the Series had not been
in operation for the year ended December 31, 1999.

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying investment division. The expenses shown below include both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

JNL/S&P Moderate Growth Series

Investment  Objective.  The investment  objective of the JNL/S&P Moderate Growth
Series is capital growth. Current income is a secondary objective.

Principal Investment  Strategies.  The Series seeks to achieve its objectives by
investing  in a  diversified  group of other  Series  of the  Trust  (Underlying
Series).  The Underlying  Series in which the JNL/S&P Moderate Growth Series may
invest are the  JNL/Alliance  Growth Series,  JNL/J.P.  Morgan  Enhanced S&P 500
Stock Index Series,  JNL/J.P.  Morgan  International & Emerging  Markets Series,
JNL/Janus Aggressive Growth Series,  JNL/Janus Global Equities Series, JNL/Janus
Growth & Income Series, JNL/PIMCO Total Return Bond Series, Lazard/JNL Small Cap
Value Series,  Lazard/JNL  Mid Cap Value Series,  PPM  America/JNL  Money Market
Series, JNL/Putnam International Equity Series, JNL/Putnam Midcap Growth Series,
Salomon Brothers/JNL  Balanced Series,  Salomon Brothers/JNL Global Bond Series,
Salomon  Brothers/JNL  High Yield Bond  Series,  and T. Rowe  Price/JNL  Mid-Cap
Growth Series.

The Series seeks to achieve capital growth through its investments in Underlying
Series that invest primarily in equity securities. These investments may include
Series that  invest in stocks of large  established  companies  as well as those
that invest in stocks of smaller companies with above-average growth potential.

The Series seeks to achieve  current income through its investment in Underlying
Series that invest primarily in fixed-income  securities.  These investments may
include Underlying Series that invest exclusively in bonds of U.S. corporate and
government   issuers  and   Underlying   Series  that  invest   exclusively   in
investment-grade securities.

Under normal circumstances, the Series allocates approximately 60% to 80% of its
assets to Underlying  Series that invest primarily in equity  securities and 20%
to 40% to Underlying  Series that invest  primarily in fixed-income  securities.
Within these asset  classes,  the Series  remains  flexible  with respect to the
percentage it will allocate among particular Underlying Series.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and  you  could  lose  money  by  investing  in the  Series.  Since  the  Series
concentrates its investments in shares of the Underlying Series, its performance
is  directly  related  to the  ability  of the  Underlying  Series to meet their
respective investment objectives,  as well as the sub-adviser's allocation among
the  Underlying  Series.  Accordingly,  a variety of factors may  influence  its
performance, such as:

         o        Market risk.  Because the Series invests  indirectly in stocks
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of an  unanticipated  default,  a Series  would  experience  a
                  reduction in its income,  a decline in the market value of the
                  securities  so  affected  and a  decline  in the  value of its
                  shares.  During an economic downturn or substantial  period of
                  rising interest rates, highly leveraged issuers may experience
                  financial stress which could adversely affect their ability to
                  service  principal and interest payment  obligations,  to meet
                  projected  business goals and to obtain additional  financing.
                  The market prices of lower-rated securities are generally less
                  sensitive  to  interest   rate   changes   than   higher-rated
                  investments,   but  more  sensitive  to  adverse  economic  or
                  political changes, or individual  developments specific to the
                  issuer.  Periods of  economic  or  political  uncertainty  and
                  change can be  expected to result in  volatility  of prices of
                  these securities.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate more than if it held only U.S. securities.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging markets may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        Currency risk.  The value of an Underlying  Series' shares may
                  change as a result of changes in exchange  rates  reducing the
                  value  of  the  U.S.  dollar  value  of  the  Series'  foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

Because the Series invests  exclusively in other series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
series.

Performance.  The  performance  of the Series  will vary from year to year.  The
Series'  performance  figures will not reflect the deduction of any charges that
are  imposed  under a variable  insurance  contract.  Those  charges,  which are
described  in  the  variable  insurance  prospectus,  will  reduce  the  Series'
performance.  As with all mutual funds,  the Series' past  performance  does not
necessarily indicate how it will perform in the future.

Performance for the Series has not been included because the Series had not been
in operation for the year ended December 31, 1999.

Shareholder Transaction Expenses (fees paid directly from your investment)
         Maximum Sales Load Imposed on Purchases                           None
         Maximum Sales Load Imposed on Reinvested Dividends                None
         Deferred Sales Load                                               None
         Redemption Fee                                                    None
         Exchange Fee                                                      None

Expenses.  The table below  shows  certain  expenses  you will incur as a Series
investor.

--------------------------------------------------------------------------------
Annual Series Operating Expenses (expenses that are deducted from Series assets)
--------------------------------------------------------------------------------
Management/Administrative Fee                                        0.20%
--------------------------------------------------------------------------------
Other Expenses                                                          0%
--------------------------------------------------------------------------------
Total Series Annual Operating Expenses                               0.20%
--------------------------------------------------------------------------------

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying investment division. The expenses shown below include both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

         JNL/S&P Moderate Growth Series ............................  1.00%

Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

JNL/S&P Aggressive Growth Series

Investment Objective.  The investment objective of the JNL/S&P Aggressive Growth
Series is capital growth. Current income is a secondary objective.

Principal Investment  Strategies.  The Series seeks to achieve its objectives by
investing  in a  diversified  group of other  Series  of the  Trust  (Underlying
Series). The Underlying Series in which the JNL/S&P Aggressive Growth Series may
invest are the  JNL/Alliance  Growth Series,  JNL/J.P.  Morgan  Enhanced S&P 500
Stock Index Series,  JNL/J.P.  Morgan  International & Emerging  Markets Series,
JNL/Janus Aggressive Growth Series,  JNL/Janus Global Equities Series, JNL/Janus
Growth & Income Series, JNL/PIMCO Total Return Bond Series, Lazard/JNL Small Cap
Value Series,  Lazard/JNL  Mid Cap Value Series,  PPM  America/JNL  Money Market
Series, JNL/Putnam International Equity Series, JNL/Putnam Midcap Growth Series,
Salomon Brothers/JNL  Balanced Series,  Salomon Brothers/JNL Global Bond Series,
Salomon  Brothers/JNL  High Yield Bond  Series,  and T. Rowe  Price/JNL  Mid-Cap
Growth Series.

The Series seeks to achieve capital growth through its investments in Underlying
Series that invest primarily in equity securities. These investments may include
Series that  invest in stocks of large  established  companies  as well as those
that invest in stocks of smaller companies with above-average growth potential.

The Series seeks to achieve  current income through its investment in Underlying
Series that invest primarily in fixed-income  securities.  These investments may
include Underlying Series that invest exclusively in bonds of U.S. corporate and
government   issuers  and   Underlying   Series  that  invest   exclusively   in
investment-grade securities.

Under normal  circumstances,  the Series  allocates 75% to 100% of its assets to
Underlying  Series that invest  primarily in equity  securities and 0% to 25% to
Underlying Series that invest primarily in fixed-income securities. Within these
asset  classes,  the Series  remains  flexible with respect to the percentage it
will allocate among particular Underlying Series.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and  you  could  lose  money  by  investing  in the  Series.  Since  the  Series
concentrates its investments in shares of the Underlying Series, its performance
is  directly  related  to the  ability  of the  Underlying  Series to meet their
respective investment objectives,  as well as the sub-adviser's allocation among
the  Underlying  Series.  Accordingly,  a variety of factors may  influence  its
performance, such as:

         o        Market risk.  Because the Series invests  indirectly in stocks
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of an  unanticipated  default,  a Series  would  experience  a
                  reduction in its income,  a decline in the market value of the
                  securities  so  affected  and a  decline  in the  value of its
                  shares.  During an economic downturn or substantial  period of
                  rising interest rates, highly leveraged issuers may experience
                  financial stress which could adversely affect their ability to
                  service  principal and interest payment  obligations,  to meet
                  projected  business goals and to obtain additional  financing.
                  The market prices of lower-rated securities are generally less
                  sensitive  to  interest   rate   changes   than   higher-rated
                  investments,   but  more  sensitive  to  adverse  economic  or
                  political changes, or individual  developments specific to the
                  issuer.  Periods of  economic  or  political  uncertainty  and
                  change can be  expected to result in  volatility  of prices of
                  these securities.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause an Underlying  Series'  performance to
                  fluctuate more than if it held only U.S. securities.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in one or more  Underlying  Series that hold securities
                  of issuers in emerging  markets,  which involves greater risk.
                  Emerging   market   countries   typically  have  economic  and
                  political systems that are less fully developed, and likely to
                  be  less  stable,  than  those  of  more  advanced  countries.
                  Emerging  market  countries  may have  policies  that restrict
                  investment  by  foreigners,  and  there is a higher  risk of a
                  government taking private property. Low or nonexistent trading
                  volume in securities of issuers in emerging markets may result
                  in a lack of  liquidity  and in price  volatility.  Issuers in
                  emerging markets  typically are subject to a greater degree of
                  change in earnings and business  prospects  than are companies
                  in developed markets.

         o        Currency risk.  The value of an Underlying  Series' shares may
                  change as a result of changes in exchange  rates  reducing the
                  value  of  the  U.S.  dollar  value  of  the  Series'  foreign
                  investments.  Currency  exchange  rates  can be  volatile  and
                  affected by a number of factors, such as the general economics
                  of a country,  the actions of U.S. and foreign  governments or
                  central  banks,  the  imposition  of  currency  controls,  and
                  speculation.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

Because the Series invests  exclusively in other series of the Trust, you should
look elsewhere in this  prospectus for the  particular  information  about those
series.

Performance.  The  performance  of the Series  will vary from year to year.  The
Series'  performance  figures will not reflect the deduction of any charges that
are  imposed  under a variable  insurance  contract.  Those  charges,  which are
described  in  the  variable  insurance  prospectus,  will  reduce  the  Series'
performance.  As with all mutual funds,  the Series' past  performance  does not
necessarily indicate how it will perform in the future.

Performance for the Series has not been included because the Series had not been
in operation for the year ended December 31, 1999.

Expenses.  The table below  shows  certain  expenses  you will incur as a Series
investor.

------------------------------------------------------------------------------
Annual Series Operating Expenses (expenses that are deducted from Series assets)
------------------------------------------------------------------------------
Management/Administrative Fee                                            0.20%
------------------------------------------------------------------------------
Other Expenses                                                              0%
------------------------------------------------------------------------------
Total Series Annual Operating Expenses                                   0.20%
------------------------------------------------------------------------------

As a  shareholder  of an  Underlying  Series,  the Series will bear its pro rata
share  of the  expenses  of  that  Underlying  Series,  which  could  result  in
duplication of certain fees, including management and administration fees.

The total annual operating  expenses for each JNL/S&P Series (including both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses  for the  underlying  investment  divisions)  could  range from .90% to
1.38%. The table below shows estimated total annual operating  expenses for each
JNL/S&P  Series based on the pro rata share of expenses that the JNL/S&P  Series
would bear if they  invested  in a  hypothetical  mix of  underlying  investment
divisions.  The  adviser  believes  the  expenses  shown  below  to be a  likely
approximation  of the expenses the JNL/S&P Series will incur based on the actual
mix of underlying investment division. The expenses shown below include both the
annual  operating  expenses  for the  JNL/S&P  Series and the  annual  operating
expenses for the underlying  investment  divisions.  The actual expenses of each
JNL/S&P  Series  will  be  based  on the  actual  mix of  underlying  investment
divisions in which it invests.  The actual  expenses may be greater or less than
those shown.

         JNL/S&P Aggressive Growth Series .............................  1.17%

Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

JNL Enhanced Intermediate Bond Index Series

Investment Objective.  The investment objective of the JNL Enhanced Intermediate
Bond Fund Index  Series is to match or exceed the return of the Lehman  Brothers
Intermediate Government/Corporate Bond Index.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
utilizing an enhanced bond indexing  strategy  intended to add incremental value
over  the  Lehman  Brothers   Intermediate   Government/Corporate   Index  in  a
risk-controlled  framework.  The JNL  Enhanced  Intermediate  Bond Index  Series
invests primarily in U.S.  dollar-denominated U.S. Treasury,  Agency, corporate,
and mortgage- and other asset-backed securities, and supranational and sovereign
debt obligations.  The Series invests at least 65% in a diversified portfolio of
intermediate-maturity,  investment-grade  fixed-income securities The Series has
no  policy  regarding  the  quality  and  maturity  of the  bonds  which  may be
purchased..
The sub-adviser may engage in options,  financial  futures and swap transactions
in seeking to hedge the portfolio or enhance return.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series  invests in the securities of
                  U.S. and foreign  issuers,  it is subject to market risk.  For
                  bonds, market risk generally reflects credit risk and interest
                  rate risk.  Credit risk is the actual or  perceived  risk that
                  the issuer of the bond will not pay the interest and principal
                  payments  when  due.  Bond  value  typically  declines  if the
                  issuer's  credit quality  deteriorates.  Interest rate risk is
                  the risk that interest rates will rise and the value of bonds,
                  including  those held by the Series,  will fall. A broad-based
                  market drop may also cause a bond's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Derivatives risk. Investing in derivative instruments, such as
                  options,   futures  contracts,   forward  currency  contracts,
                  indexed  securities  and  asset-backed  securities,   involves
                  special risks. The Series' sub-advisers must correctly predict
                  the price movements,  during the life of a derivative,  of the
                  underlying  asset in order to realize the desired results from
                  the investment. The value of derivatives may rise or fall more
                  rapidly  than  other  investments,   which  may  increase  the
                  volatility of the Series depending on the nature and extent of
                  the derivatives in the Series'  portfolio.  If the sub-adviser
                  uses  derivatives  in  attempting  to  manage or  "hedge"  the
                  overall  risk of the  portfolio,  the  strategy  might  not be
                  successful,  for  example,  due to changes in the value of the
                  derivatives  that do not correlate with price movements in the
                  rest of the portfolio.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The  performance  of the Series  will vary from year to year.  The
Series'  performance  figures will not reflect the deduction of any charges that
are  imposed  under a variable  insurance  contract.  Those  charges,  which are
described  in  the  variable  insurance  prospectus,  will  reduce  the  Series'
performance.  As with all mutual funds,  the Series' past  performance  does not
necessarily indicate how it will perform in the future.

Performance  for the Series  has not been  included  because  the Series had not
commenced operations as of the date of this prospectus.

Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series.  The Series may invest in money market funds  including
those for which the sub-adviser acts as an investment  adviser. As a shareholder
in a money market fund, the Series would bear its share of that fund's expenses.

The sub-adviser uses a combination of quantitative  and qualitative  analysis in
balancing the top-down sector decision - selecting among government obligations,
corporate  securities and structured  investments - with the bottom-up  security
selection which is based upon fundamental and technical analysis.

The Series may invest in when-issued  and delayed  delivery  securities.  Actual
payment for and delivery of such  securities does not take place until some time
in the future, i.e., beyond normal settlement.  The purchase of these securities
will result in a loss if their value declines prior to the settlement date. This
could occur, for example, if interest rates increase prior to settlement.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

JNL International Index Series

Investment  Objective.  The investment  objective of the JNL International Index
Series is to  closely  match  the  performance  of the  Morgan  Stanley  Capital
International Europe and Australasia, Far East Equity Index (MSCI E.A.FE. Index)
while minimizing transaction costs.

Principal  Investment  Strategies.  The Series  seeks to achieve  its  objective
through a diversified portfolio whose returns closely parallel those of the MSCI
E.A.FE.  Index. The Series typically holds all securities  contained in the MSCI
E.A.FE.  Index.  To better  track  the  performance  of the  Index  and  provide
liquidity,  the  Series  may hold  E.A.FE.  futures  contracts  instead  of cash
equivalents in its portfolio.  The sub-adviser uses a trading approach  intended
to reduce the Series' transaction costs.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series  invests in stocks of foreign
                  companies,  it is subject to stock market  risk.  Stock prices
                  typically  fluctuate  more than the  values of other  types of
                  securities, typically in response to changes in the particular
                  company's financial condition and factors affecting the market
                  in general.  For example,  unfavorable or  unanticipated  poor
                  earnings performance of the company may result in a decline in
                  its  stock's  price,  and a  broad-based  market drop may also
                  cause a stock's price to fall.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in  securities  of issuers in emerging  markets,  which
                  involves  greater risk.  Emerging market  countries  typically
                  have  economic  and  political  systems  that are  less  fully
                  developed,  and likely to be less  stable,  than those of more
                  advanced   countries.   Emerging  market  countries  may  have
                  policies that restrict investment by foreigners,  and there is
                  a higher risk of a government taking private property.  Low or
                  nonexistent   trading  volume  in  securities  of  issuers  in
                  emerging  markets  may  result in a lack of  liquidity  and in
                  price  volatility.  Issuers in emerging markets  typically are
                  subject to a greater degree of change in earnings and business
                  prospects than are companies in developed markets.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

         o        Derivatives risk. Investing in derivative instruments, such as
                  options,   futures  contracts,   forward  currency  contracts,
                  indexed  securities  and  asset-backed  securities,   involves
                  special risks. The Series  sub-adviser must correctly  predict
                  price  movements,  during  the  life of a  derivative,  of the
                  underlying  asset in order to realize the desired results from
                  the investment. The value of derivatives may rise or fall more
                  rapidly  than  other  investments,   which  may  increase  the
                  volatility of the Series depending on the nature and extent of
                  the derivatives in the Series'  portfolio.  If the sub-adviser
                  uses  derivatives  in  attempting  to  manage or  "hedge"  the
                  overall  risk of the  portfolio,  the  strategy  might  not be
                  successful,  for  example,  due to changes in the value of the
                  derivatives  that do not correlate with price movements in the
                  rest of the portfolio.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The  performance  of the Series  will vary from year to year.  The
Series'  performance  figures will not reflect the deduction of any charges that
are  imposed  under a variable  insurance  contract.  Those  charges,  which are
described  in  the  variable  insurance  prospectus,  will  reduce  the  Series'
performance.  As with all mutual funds,  the Series' past  performance  does not
necessarily indicate how it will perform in the future.

Performance  for the Series  has not been  included  because  the Series had not
commenced operations as of the date of this prospectus.

JNL Russell 2000 Index Series

Investment  Objective.  The  investment  objective of the JNL Russell 2000 Index
Series is to closely match the returns and  characteristics  of the Russell 2000
Index.

Principal  Investment  Strategies.  The Series  seeks to achieve  its  objective
through a diversified  portfolio whose return closely tracks that of the Russell
2000 Index.  The Series  typically  holds all the common stocks  included in the
Russell 2000 Index.

The  sub-adviser  generally  follows a buy and hold strategy,  trading only when
there is a change in the composition of the Russell 2000 Index or when cash flow
activity occurs in the Series.  The sub-adviser uses a trading approach intended
to reduce the Series' transaction costs.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market  risk.  Because  the  Series  invests in stocks of U.S.
                  companies,  it is subject to stock market  risk.  Stock prices
                  typically  fluctuate  more than the  values of other  types of
                  securities, typically in response to changes in the particular
                  company's financial condition and factors affecting the market
                  in general.  For example,  unfavorable or  unanticipated  poor
                  earnings performance of the company may result in a decline in
                  its  stock's  price,  and a  broad-based  market drop may also
                  cause a stock's price to fall.

         o        Small  cap  investing  risk.   Investing  in  smaller,   newer
                  companies  generally  involves greater risks than investing in
                  larger,  more  established  ones.  The  companies in which the
                  Series is likely to invest have limited product lines, markets
                  or financial  resources,  or may depend on the  expertise of a
                  few  people,  and may be  subject  to more  abrupt or  erratic
                  market  movements than securities of larger,  more established
                  companies or the market averages in general. In addition, many
                  small  capitalization  companies may be in the early stages of
                  development.  Accordingly, an investment in the Series may not
                  be appropriate for all investors.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The  performance  of the Series  will vary from year to year.  The
Series'  performance  figures will not reflect the deduction of any charges that
are  imposed  under a variable  insurance  contract.  Those  charges,  which are
described  in  the  variable  insurance  prospectus,  will  reduce  the  Series'
performance.  As with all mutual funds,  the Series' past  performance  does not
necessarily indicate how it will perform in the future.

Performance  for the Series  has not been  included  because  the Series had not
commenced operations as of the date of this prospectus.

JNL S&P 500 Index Series

Investment  Objective.  The investment objective of the JNL S&P 500 Index Series
is to closely match the returns and characteristics of the Standard & Poor's 500
Composite Stock Price Index (S&P 500 Index).

Principal  Investment  Strategies.  The Series  seeks to achieve  its  objective
through a diversified  portfolio whose return closely tracks that of the S&P 500
Index.  The  Series  typically  holds  all the  stock  in the S&P 500  Index  in
approximately  the same proportions as they appear in the Index. To better track
the performance of the Index and provide liquidity,  the Series may hold S&P 500
futures contracts instead of cash equivalents in its portfolio.  The sub-adviser
generally  follows a buy and hold strategy,  trading only when there is a change
in the composition of the S&P 500 Index or when cash flow activity occurs in the
Series.  The sub-adviser uses a trading approach  intended to reduce the Series'
transaction costs.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series invests in stocks of U.S. and
                  foreign  companies,  it is subject to stock market risk. Stock
                  prices typically fluctuate more than the values of other types
                  of  securities,  typically  in  response  to  changes  in  the
                  particular company's financial condition and factors affecting
                  the  market  in   general.   For   example,   unfavorable   or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

Lazard/JNL Mid Cap Value Series

Investment  Objective.  The investment objective of the Lazard/JNL Mid Cap Value
Series is capital appreciation.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing at least 80% of total assets in a non-diversified  portfolio of equity
securities  of U.S.  companies  with  market  capitalizations  in the  range  of
companies  represented  in the  Russell  Mid Cap Index and that the  sub-adviser
believes are  undervalued  based on their return on equity.  The Russell Mid Cap
Index is composed of selected common stocks of medium-size U.S.  companies.  The
Series' equity holdings consist  primarily of common stocks but may also include
preferred stocks, securities convertible into or exchangeable for common stocks,
rights and  warrants,  real estate  investment  trusts and  American  and Global
Depositary  Receipts.  To the  extent  its  assets  are  not  invested  in  such
securities,   the  Series  may  invest  in  the  equity   securities  of  larger
capitalization  companies  or  investment  grade  fixed-income  securities.   In
searching for undervalued medium  capitalization  stocks, the sub-adviser uses a
stock-selection  process  based  primarily on analysis of  historical  financial
data, with little emphasis placed on forecasting future earnings or events.

The  sub-adviser  does  not   automatically   sell  a  security  if  its  market
capitalization  grows or falls  outside  the range of  companies  in the Russell
Midcap  Index.  The  sub-adviser  may sell a security  for any of the  following
reasons:

         o        its price rises to a level where it no longer  reflects  value
                  (target valuation);

         o        the underlying investment assumptions are no longer valid;

         o        company management changes their direction; or

         o        external events occur (e.g., changes in regulation,  taxes and
                  competitive position).

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series  invests  primarily in equity
                  securities  of U.S.  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

         o        Value investing risk. The value approach carries the risk that
                  the market will not recognize a security's intrinsic value for
                  a long  time,  or that a stock  judged to be  undervalued  may
                  actually be appropriately priced.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.

investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the  Series.  The Series may use  derivative  instruments,  such as
options and futures contracts and forward currency contracts,  for hedging or to
enhance return.  These  instruments are subject to transaction costs and certain
risks,  such as  unanticipated  changes in  securities  prices.  For  temporary,
defensive  purposes,  the  Series  may  invest up to all of its assets in larger
capitalization companies, cash and short-term money market instruments. Taking a
defensive  position may reduce the  potential  for  appreciation  of the Series'
portfolio.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

Lazard/JNL Small Cap Value Series

Investment Objective. The investment objective of the Lazard/JNL Small Cap Value
Series is capital appreciation.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing  at least 80% of its total  assets in a  non-diversified  portfolio of
equity securities of U.S. companies with market  capitalizations in the range of
companies  represented by the Russell 2000 Index that the  sub-adviser  believes
are  undervalued  based on their  return on equity.  The  Russell  2000 Index is
composed  of  selected  common  stocks  of  small,   generally  unseasoned  U.S.
companies.  The Series' equity holdings  consist  primarily of common stocks but
may also include preferred stocks,  securities  convertible into or exchangeable
for common  stocks,  rights and  warrants,  real  estate  investment  trusts and
American and Global Depositary  Receipts.  The Lazard/JNL Small Cap Value Series
invests in equity securities of small U.S.  companies that, in the sub-adviser's
opinion, have one or more of the following characteristics:  (i) are undervalued
relative to their earnings,  cash flow, or asset values; (ii) have an attractive
price/value  relationship  with  expectations  that some catalyst will cause the
perception  of value to  change  within 2 years;  (iii)  are out of favor due to
circumstances  which are  unlikely to harm the  company's  franchise or earnings
power;  (iv)  have  low  projected   price-to-earnings   or   price-to-cash-flow
multiples;  (v) have the  potential to become a larger  factor in the  company's
business; (vi) have significant debt but have high levels of free cash flow; and
(vii) have a relatively  short corporate  history with the expectation  that the
business may grow. In searching for undervalued small capitalization stocks, the
sub-adviser  uses a  stock-selection  process  based  primarily  on  analysis of
historical  financial data,  with little  emphasis placed on forecasting  future
earnings or events.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series invests in equity securities,
                  it is subject to stock  market risk.  Stock  prices  typically
                  fluctuate  more than the values of other types of  securities,
                  typically in response to changes in the  particular  company's
                  financial  condition  and  factors  affecting  the  market  in
                  general.  For  example,   unfavorable  or  unanticipated  poor
                  earnings performance of the company may result in a decline in
                  its  stock's  price,  and a  broad-based  market drop may also
                  cause a stock's price to fall.

         o        Value investing risk. The value approach carries the risk that
                  the market will not recognize a security's intrinsic value for
                  a long  time,  or that a stock  judged to be  undervalued  may
                  actually be appropriately priced.

         o        Small  cap  investing  risk.   Investing  in  smaller,   newer
                  companies  generally  involves greater risks than investing in
                  larger,  more  established  ones.  The  companies in which the
                  Series is likely to invest have limited product lines, markets
                  or financial  resources,  or may depend on the  expertise of a
                  few people and may be subject to more abrupt or erratic market
                  movements  than   securities  of  larger,   more   established
                  companies or the market averages in general. In addition, many
                  small  capitalization  companies may be in the early stages of
                  development.  Accordingly, an investment in the Series may not
                  be appropriate for all investors.

         o        Non-diversification.  The Series is "non-diversified." Under a
                  definition  provided by the Investment Company Act of 1940, as
                  amended,  non-diversified funds may invest in fewer assets, or
                  in larger  proportions  of the assets of single  companies  or
                  industries.  Thus,  the  Series  may hold a smaller  number of
                  issuers than if it were  "diversified."  With a smaller number
                  of different issuers,  the Series is subject to more risk than
                  another fund holding a larger number of issuers, since changes
                  in the financial condition or market status of a single issuer
                  may cause greater  fluctuation in the Series' total return and
                  share price.

In addition,  the performance of the Series depends on the sub-adviser's ability

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series.  The sub-adviser does not automatically sell a security
if its market  capitalization  grows or falls  outside the range of companies in
the  Russell  2000 Index.  The  sub-adviser  may sell a security  for any of the
following reasons:

         o        its price rises to a level where it no longer  reflects  value
                  (target valuation);

         o        the underlying investment assumptions are no longer valid;

         o        company management changes their direction; or

         o        external events occur (e.g., changes in regulation,  taxes and
                  competitive position).

The  Series  may  invest  in  equity  securities  of larger  U.S.  companies  or
investment grade fixed-income securities.

The Series may use derivative instruments, such as options and futures contracts
and  forward  currency  contracts,  for  hedging  or to  enhance  return.  These
instruments  are  subject  to  transaction  costs  and  certain  risks,  such as
unanticipated changes in securities prices.

For temporary, defensive purposes, the Series may invest up to all of its assets
in  larger   capitalization   companies,   cash  and  short-term   money  market
instruments.   Taking  a  defensive   position  may  reduce  the  potential  for
appreciation of the Series' portfolio.

PPM America/JNL Balanced Series

Investment  Objective.  The investment objective of the PPM America/JNL Balanced
Series is  reasonable  income,  long-term  capital  growth and  preservation  of
capital.

Principal Investment  Strategies.  The Series seeks to achieve its objectives by
investing primarily in a diversified  portfolio of common stock and fixed-income
securities of U.S. companies, but may also invest in securities convertible into
common stocks,  deferred debt  obligations and zero coupon bonds. The Series may
invest in any type or class of  security.  The  anticipated  mix of the  Series'
holdings  is  approximately  45-75% of its  assets  in  equities  and  25-55% in
fixed-income securities.

The Series emphasizes  investment-grade,  fixed-income securities.  However, the
Series  may  take  a  modest  position  in  lower-  or  non-rated   fixed-income
securities, and if, in the sub-adviser's opinion, market conditions warrant, may
increase its position in lower- or non-rated securities from time to time.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series invests in equity  securities
                  of U.S.  companies,  it is subject to stock market risk. Stock
                  prices typically fluctuate more than the values of other types
                  of  securities,  typically  in  response  to  changes  in  the
                  particular company's financial condition and factors affecting
                  the  market  in   general.   For   example,   unfavorable   or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those  held by the  Series,  will  fall.  A
                  broad-based market drop may also cause a bond's price to fall.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of an  unanticipated  default,  the Series would  experience a
                  reduction in its income,  a decline in the market value of the
                  securities  so  affected  and a  decline  in the  value of its
                  shares.  During an economic downturn or substantial  period of
                  rising interest rates, highly leveraged issuers may experience
                  financial stress which could adversely affect their ability to
                  service  principal and interest payment  obligations,  to meet
                  projected  business goals and to obtain additional  financing.
                  The market prices of lower-rated securities are generally less
                  sensitive  to  interest   rate   changes   than   higher-rated
                  investments,   but  more  sensitive  to  adverse  economic  or
                  political changes, or individual  developments specific to the
                  issuer.  Periods of  economic  or  political  uncertainty  and
                  change can be  expected to result in  volatility  of prices of
                  these securities.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

PPM America/JNL High Yield Bond Series

Investment  Objective.  The primary investment  objective of the PPM America/JNL
High  Yield  Bond  Series is to  provide a high  level of  current  income;  its
secondary   investment   objective  is  capital  appreciation  by  investing  in
fixed-income   securities,   with  emphasis  on  higher-yielding,   higher-risk,
lower-rated or unrated corporate bonds.

Principal Investment Strategies. The Series attempts to achieve its objective by
investing  substantially in a diversified  portfolio of long-term (over 10 years
to maturity)  and  intermediate-term  (3 to 10 years to  maturity)  fixed-income
securities  of U.S.  and foreign  issuers,  with  emphasis  on  higher-yielding,
higher-risk,  lower-rated or unrated  corporate bonds. The Series will invest at
least 65% in "junk bonds," which are bonds rated Ba or below by Moody's or BB or
below by S&P or, if unrated,  considered by the  sub-adviser to be of comparable
quality.  However,  the Series will not invest more than 10% of its total assets
in bonds  rated C by  Moody's  or D by S&P (or  unrated  but  considered  by the
sub-adviser  to be of  comparable  quality).  Lower-rated  securities  generally
involve  a  higher  risk of  default  than  higher-rated  ones.In  pursuing  its
secondary investment objective of capital appreciation,  the Series may purchase
high-yield  bonds that the  sub-adviser  expects  will  increase in value due to
improvements  in their  credit  quality or ratings or  anticipated  declines  in
interest rates. In addition, the Series may invest for this purpose up to 25% of
its assets in equity securities, such as common stocks or securities convertible
into or exchangeable for common stock.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series  invests in the securities of
                  U.S. and foreign  issuers,  it is subject to market risk.  For
                  bonds, market risk generally reflects credit risk and interest
                  rate risk.  Credit risk is the actual or  perceived  risk that
                  the issuer of the bond will not pay the interest and principal
                  payments  when  due.  Bond  value  typically  declines  if the
                  issuer's  credit quality  deteriorates.  Interest rate risk is
                  the risk that interest rates will rise and the value of bonds,
                  including  those held by the Series,  will fall. A broad-based
                  market drop may also cause a bond's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

                  To the extent the Series  invests in the equity  securities of
                  U.S.  and  foreign  companies,  it is subject to stock  market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of an  unanticipated  default,  the Series would  experience a
                  reduction in its income,  a decline in the market value of the
                  securities  so  affected  and a  decline  in the  value of its
                  shares.  During an economic downturn or substantial  period of
                  rising interest rates, highly leveraged issuers may experience
                  financial stress which could adversely affect their ability to
                  service  principal and interest payment  obligations,  to meet
                  projected  business goals and to obtain additional  financing.
                  The market prices of lower-rated securities are generally less
                  sensitive  to  interest   rate   changes   than   higher-rated
                  investments,   but  more  sensitive  to  adverse  economic  or
                  political changes, or individual  developments specific to the
                  issuer.  Periods of  economic  or  political  uncertainty  and
                  change can be  expected to result in  volatility  of prices of
                  these securities.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.  To the extent that
                  the Series  invests in bonds  issued by a foreign  government,
                  the Series may have  limited  legal  recourse  in the event of
                  default.   Political   conditions,   especially   a  country's
                  willingness  to meet the  terms of its debt  obligations,  can
                  create special risks.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

Treating high current income as its primary investment  objective means that the
Series  may forego  opportunities  that  would  result in capital  gains and may
accept  prudent  risks to  capital  value,  in each  case to take  advantage  of
opportunities  for higher current  income.  In addition,  the performance of the
Series  depends  on the  sub-adviser's  ability  to  effectively  implement  the
investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

PPM America/JNL Money Market Series

Investment  Objective.  The investment  objective of the PPM  America/JNL  Money
Market  Series is to achieve as high a level of current  income as is consistent
with the  preservation  of capital and  maintenance of liquidity by investing in
high quality, short-term money market instruments.

Principal  Investment  Strategies.  The Series invests in the following types of
high quality,  U.S.  dollar-denominated  money market instruments that mature in
397 days or less.

         o        Obligations  issued or guaranteed as to principal and interest
                  by the U.S. Government, its agencies and instrumentalities;

         o        Obligations,  such as time deposits,  certificates  of deposit
                  and  bankers  acceptances,  issued by U.S.  banks and  savings
                  banks  that  are  members  of the  Federal  Deposit  Insurance
                  Corporation,  including  their  foreign  branches  and foreign
                  subsidiaries,  and issued by domestic and foreign  branches of
                  foreign banks;

         o        Corporate obligations, including commercial paper, of domestic
                  and foreign issuers;

         o        Obligations  issued  or  guaranteed  by  one or  more  foreign
                  governments or any of their political  subdivisions,  agencies
                  or  instrumentalities,  including obligations of supranational
                  entities; and

         o        Repurchase  agreements on obligations  issued or guaranteed by
                  the U.S. Government, its agencies or instrumentalities.

The sub-adviser  manages the Series to meet the  requirements of Rule 2a-7 under
the Investment  Company Act of 1940, as amended,  including those as to quality,
diversification and maturity.  The Series may invest more than 25% of its assets
in the U.S. banking industry.

Principal  Risks of Investing in the Series.  An investment in the Series is not
insured or guaranteed by the Federal Deposit Insurance  Corporation or any other
government  agency.  Although  the Series  seeks to  preserve  the value of your
investment at $1.00 per share,  you could lose money by investing in the Series.
A variety of factors may influence its investment performance, such as:

         o        Market risk. Fixed income securities in general are subject to
                  credit  risk and  market  risk.  Credit  risk is the actual or
                  perceived  risk  that the  issuer of the bond will not pay the
                  interest and principal payments when due. Bond value typically
                  declines if the issuer's credit quality  deteriorates.  Market
                  risk,  also  known as  interest  rate  risk,  is the risk that
                  interest  rates  will rise and the  value of bonds,  including
                  those held by the Series, will fall. A broad-based market drop
                  may also cause a bond's price to fall.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

Salomon Brothers/JNL Balanced Series

Investment  Objective.  The  investment  objective  of the Salomon  Brothers/JNL
Balanced  Series  is to  obtain  above-average  income.  The  Series'  secondary
objective  is to take  advantage  of  opportunities  for growth of  capital  and
income.

Principal Investment  Strategies.  The Series seeks to achieve its objectives by
investing in a diversified portfolio of a broad variety of securities, including
equity  securities,  fixed-income  securities  and short-term  obligations.  The
Series may vary the percentage of assets invested in any one type of security in
accordance with the sub-adviser's view of existing and anticipated  economic and
market conditions, fiscal and monetary policy and underlying security values.

Under normal market  conditions,  approximately  40% of the Series'  assets will
consist of equity  securities.  Equity holdings may include common and preferred
stock,  securities  convertible  into  common or  preferred  stock,  rights  and
warrants,  equity interests in trusts,  partnerships,  joint ventures or similar
enterprises, and Depositary Receipts.

The  sub-adviser  may  invest  up to 25% in the  full  range  of  maturities  of
fixed-income  securities,  which may include  corporate  debt  securities,  U.S.
Government securities,  mortgage-backed  securities, zero coupon bonds, deferred
interest bonds and payment-in-kind  securities.  Generally,  most of the Series'
long-term debt investments consist of investment grade securities,  although the
Series may invest in  non-investment  grade  securities  commonly known as "junk
bonds." The Series may also invest in foreign securities.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series invests in equity  securities
                  of U.S. and foreign  companies,  it is subject to stock market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those  held by the  Series,  will  fall.  A
                  broad-based market drop may also cause a bond's price to fall.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of an  unanticipated  default,  the Series would  experience a
                  reduction in its income,  a decline in the market value of the
                  securities  so  affected  and a  decline  in the  value of its
                  shares.  During an economic downturn or substantial  period of
                  rising interest rates, highly leveraged issuers may experience
                  financial stress which could adversely affect their ability to
                  service  principal and interest payment  obligations,  to meet
                  projected  business goals and to obtain additional  financing.
                  The market prices of lower-rated securities are generally less
                  sensitive  to  interest   rate   changes   than   higher-rated
                  investments,   but  more  sensitive  to  adverse  economic  or
                  political changes, or individual  developments specific to the
                  issuer.  Periods of  economic  or  political  uncertainty  and
                  change can be  expected to result in  volatility  of prices of
                  these securities.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

In addition,  the performance of the Series depends on the sub-adviser's ability

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This

future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Salomon Brothers/JNL Global Bond Series

Investment   Objective.   The  primary  investment   objective  of  the  Salomon
Brothers/JNL  Global Bond Series is to seek a high level of current income. As a
secondary objective, the Series seeks capital appreciation.

Principal  Investment  Strategies.  The Salomon  Brothers/JNL Global Bond Series
invests  at  least  65%  in  a  globally   diverse   portfolio  of  fixed-income
investments.  The sub-adviser has broad  discretion to invest the Series' assets
among   certain   segments   of  the   fixed-income   market,   primarily   U.S.
investment-grade  bonds,  high-yield corporate debt securities,  emerging market
debt securities and  investment-grade  foreign debt  securities.  These segments
include  U.S.  Government   securities  and  mortgage-  and  other  asset-backed
securities (including  interest-only or principal-only  securities),  as well as
debt obligations  issued or guaranteed by a foreign  government or supranational
organization.  The Series does not  currently  intend to invest more than 75% of
assets in medium or lower rated securities.

In determining  the assets to invest in each type of security,  the  sub-adviser
relies in part on quantitative analytical techniques that measure relative risks
and  opportunities  of each type of  security  based on current  and  historical
economic,  market,  political and technical  data for each type of security,  as
well as on its own assessment of economic and market conditions both on a global
and local (country) basis. The sub-adviser  continuously  reviews the allocation
of assets for the Series and makes such adjustments as it deems appropriate. The
sub-adviser  has  discretion  to select the range of  maturities  of the various
fixed income securities in which the Series invests. The sub-adviser anticipates
that, under current market  conditions,  the Series'  portfolio  securities will
have a weighted  average life of 6 to 10 years.  However,  the weighted  average
life of the  portfolio  securities  may  vary  substantially  from  time to time
depending on economic and market conditions.

The sub-adviser may invest in medium or lower-rated  securities.  Investments of
this type involve  significantly  greater risks,  including price volatility and
risk of default in the payment of interest and  principal,  than  higher-quality
securities.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market  risk.  Because  the  Series  invests  in  fixed-income
                  securities  of U.S.  and  foreign  issuers,  it is  subject to
                  market risk. For bonds,  market risk generally reflects credit
                  risk and  interest  rate  risk.  Credit  risk is the actual or
                  perceived  risk  that the  issuer of the bond will not pay the
                  interest and principal payments when due. Bond value typically
                  declines if the issuer's credit quality deteriorates. Interest
                  rate risk is the risk that  interest  rates  will rise and the
                  value of bonds, including those held by the Series, will fall.
                  A  broad-based  market  drop may also cause a bond's  price to
                  fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.  To the extent that
                  the Series  invests in bonds  issued by a foreign  government,
                  the Series may have  limited  legal  recourse  in the event of
                  default.   Political   conditions,   especially   a  country's
                  willingness  to meet the  terms of its debt  obligations,  can
                  create special risks.

         o        High-yield/high-risk bonds. Lower rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of an  unanticipated  default,  the Series would  experience a
                  reduction in its income,  a decline in the market value of the
                  securities  so  affected  and a  decline  in the  value of its
                  shares.  During an economic downturn or substantial  period of
                  rising interest rates, highly leveraged issuers may experience
                  financial stress which could adversely affect their ability to
                  service  principal and interest payment  obligations,  to meet
                  projected  business goals and to obtain additional  financing.
                  The market prices of lower-rated securities are generally less
                  sensitive  to  interest   rate   changes   than   higher-rated
                  investments,   but  more  sensitive  to  adverse  economic  or
                  political changes, or individual  developments specific to the
                  issuer.  Periods of  economic  or  political  uncertainty  and
                  change can be  expected to result in  volatility  of prices of
                  these securities.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Emerging  markets risk. The Series may invest a portion of its
                  assets in  securities  of issuers in emerging  markets,  which
                  involves  greater risk.  Emerging market  countries  typically
                  have  economic  and  political  systems  that are  less  fully
                  developed,  and likely to be less  stable,  than those of more
                  advanced   countries.   Emerging  market  countries  may  have
                  policies that restrict investment by foreigners,  and there is
                  a higher risk of a government taking private property.  Low or
                  nonexistent   trading  volume  in  securities  of  issuers  in
                  emerging  markets  may  result in a lack of  liquidity  and in
                  price  volatility.  Issuers in emerging markets  typically are
                  subject to a greater degree of change in earnings and business
                  prospects than are companies in developed markets.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

         o        Derivatives risk. Investing in derivative instruments, such as
                  options,   futures  contracts,   forward  currency  contracts,
                  indexed  securities  and  asset-backed  securities,   involves
                  special risks. The Series  sub-adviser must correctly  predict
                  price  movements,  during  the  life of a  derivative,  of the
                  underlying  asset in order to realize the desired results from
                  the investment. The value of derivatives may rise or fall more
                  rapidly  than  other  investments,   which  may  increase  the
                  volatility of the Series depending on the nature and extent of
                  the derivatives in the Series'  portfolio.  If the sub-adviser
                  uses  derivatives  in  attempting  to  manage or  "hedge"  the
                  overall  risk of the  portfolio,  the  strategy  might  not be
                  successful,  for  example,  due to changes in the value of the
                  derivatives  that do not correlate with price movements in the
                  rest of the portfolio.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Salomon Brothers/JNL High Yield Bond Series

Investment Objective.  The investment objective of the Salomon Brothers/JNL High
Yield Bond Series is to maximize current income. As a secondary  objective,  the
Series seeks capital appreciation.

Principal Investment Strategies. The Salomon Brothers/JNL High Yield Bond Series
invests a substantial  percentage of its total assets in  high-yield,  high-risk
debt  securities,  commonly  referred to as "junk  bonds." In light of the risks
associated  with such  securities,  the  sub-adviser  takes various factors into
consideration  in evaluating the  creditworthiness  of an issuer.  For corporate
debt securities,  these typically include the issuer's financial resources,  its
sensitivity  to economic  conditions  and trends,  the operating  history of the
issuer,  and the  experience  and track record of the issuer's  management.  For
sovereign debt  instruments,  these typically include the economic and political
conditions within the issuer's  country,  the issuer's overall and external debt
levels and debt service ratios, the issuer's access to capital markets and other
sources  of  funding,  and  the  issuer's  debt  service  payment  history.  The
sub-adviser  also reviews the ratings,  if any,  assigned to the security by any
recognized  rating  agencies,  although  the  sub-adviser's  judgment  as to the
quality  of a debt  security  may  differ  from  that  suggested  by the  rating
published by a rating  service.  The Series'  ability to achieve its  investment
objectives may be more dependent on the sub-adviser's credit analysis than would
be the case if it invested in higher quality debt securities.

In  pursuing  the  Series'  secondary  objective  of capital  appreciation,  the
sub-adviser  looks for those  companies that the  sub-adviser  believes have the
highest potential for improving credit fundamentals. The Fund may also invest in
securities of foreign issuers.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market  risk.  Because  the  Series  invests  in  fixed-income
                  securities  of U.S.  and  foreign  issuers,  it is  subject to
                  market risk. For bonds,  market risk generally reflects credit
                  risk and  interest  rate  risk.  Credit  risk is the actual or
                  perceived  risk  that the  issuer of the bond will not pay the
                  interest and principal payments when due. Bond value typically
                  declines if the issuer's credit quality deteriorates. Interest
                  rate risk is the risk that  interest  rates  will rise and the
                  value of bonds, including those held by the Series, will fall.
                  A  broad-based  market  drop may also cause a bond's  price to
                  fall.

                  For bonds,  market  risk  generally  reflects  credit risk and
                  interest  rate risk.  Credit  risk is the actual or  perceived
                  risk that the issuer of the bond will not pay the interest and
                  principal  payments when due. Bond value typically declines if
                  the issuer's credit quality  deteriorates.  Interest rate risk
                  is the risk  that  interest  rates  will rise and the value of
                  bonds,  including  those held by an  Underlying  Series,  will
                  fall. A broad-based  market drop may also cause a bond's price
                  to fall.

                  To the extent the Series  invests in the equity  securities of
                  U.S.  and  foreign  companies,  it is subject to stock  market
                  risk. Stock prices typically fluctuate more than the values of
                  other types of securities, typically in response to changes in
                  the  particular  company's  financial  condition  and  factors
                  affecting the market in general.  For example,  unfavorable or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.  To the extent that
                  the Series  invests in bonds  issued by a foreign  government,
                  the Series may have  limited  legal  recourse  in the event of
                  default.   Political   conditions,   especially   a  country's
                  willingness  to meet the  terms of its debt  obligations,  can
                  create special risks.

         o        High-yield/high-risk bonds. Lower-rated bonds involve a higher
                  degree of credit risk,  which is the risk that the issuer will
                  not make interest or principal payments when due. In the event
                  of an  unanticipated  default,  a Series  would  experience  a
                  reduction in its income,  a decline in the market value of the
                  securities  so  affected  and a  decline  in the  value of its
                  shares.  During an economic downturn or substantial  period of
                  rising interest rates, highly leveraged issuers may experience
                  financial stress which could adversely affect their ability to
                  service  principal and interest payment  obligations,  to meet
                  projected  business goals and to obtain additional  financing.
                  The market prices of lower-rated securities are generally less
                  sensitive  to  interest   rate   changes   than   higher-rated
                  investments,   but  more  sensitive  to  adverse  economic  or
                  political changes, or individual  developments specific to the
                  issuer.  Periods of  economic  or  political  uncertainty  and
                  change can be  expected to result in  volatility  of prices of
                  these securities.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Expense  Example.  This  example is  intended  to help you  compare  the cost of
investing in the Series with the cost of investing in other mutual funds.  Also,
this  example  does not reflect the expenses of the  Qualified  Plan.  The table
below shows the expenses you would pay on a $10,000 investment,  assuming (1) 5%
annual  return  and  (2)  redemption  at  the  end of  each  time  period.  This
illustration is hypothetical and is not intended to be representative of past or
future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series.  The Series may invest in foreign  securities,  such as
obligations  issued or  guaranteed  by foreign  governmental  authorities,  debt
obligations  of  supranational  organizations  and  fixed-income  securities  of
foreign  corporate  issuers.  The Series may invest without limit in zero coupon
securities,  pay-in-kind  bonds and deferred payment  securities,  which involve
special risk  considerations.  The Series may invest in fixed- and floating-rate
loans,  including  loan  participations.  The Series may invest up to 10% of its
total assets in either (i) equipment lease or trust certificates and conditional
sales  contracts  or (ii)  limited  partnership  interests.  The Series may also
invest up to 10% of its total assets in equity  securities (other than preferred
stock,  in  which  the  Series  may  invest  without  limit),  typically  equity
investments acquired as a result of purchases of fixed-income securities.

The  sub-adviser  has  discretion  to  select  the  range of  maturities  of the
fixed-income  securities  in  which  the  Series  may  invest.  The  sub-adviser
anticipates that, under current market conditions,  the Series will have average
portfolio life of 10 to 15 years.  However,  the average portfolio life may vary
substantially from time to time depending on economic and market conditions.

The Series may use derivative  instruments,  such as futures contracts,  options
and forward currency contracts, and invest in indexed securities for hedging and
risk management.  These instruments are subject to transaction costs and certain
risks,  such as unanticipated  changes in securities  prices and global currency
markets.

When the sub-adviser believes that adverse conditions prevail in the markets for
high-yield  fixed-income  securities that make the Series'  investment  strategy
inconsistent with the best interests of the Series' shareholders, the Series may
invest  its  assets  without  limit in  high-quality,  short-term  money  market
instruments.  Doing so may  reduce  the  potential  for high  current  income or
appreciation of the Series' portfolio.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

Salomon Brothers/JNL U.S. Government & Quality Bond Series

Investment Objective.  The investment objective of the Salomon Brothers/JNL U.S.
Government & Quality Bond Series is to obtain a high level of current income.

Principal  Investment  Strategies.  The Salomon  Brothers/JNL U.S.  Government &
Quality Bond Series invests at least 65% of its assets in:

         (i)      U.S. Treasury obligations;

         (ii)     obligations    issued   or    guaranteed    by   agencies   or
                  instrumentalities  of the U.S.  Government which are backed by
                  their own  credit  and may not be backed by the full faith and
                  credit of the U.S. Government;

         (iii)    mortgage-backed   securities   guaranteed  by  the  Government
                  National  Mortgage  Association that are supported by the full
                  faith  and  credit  of the U.S.  Government.  Such  securities
                  entitle  the  holder to receive  all  interest  and  principal
                  payments due whether or not payments are actually  made on the
                  underlying mortgages;

         (iv)     mortgage-backed   securities   guaranteed   by   agencies   or
                  instrumentalities  of the U.S.  Government which are supported
                  by their own  credit  but not the full faith and credit of the
                  U.S.  Government,  such  as the  Federal  Home  Loan  Mortgage
                  Corporation  and Fannie Mae  (formerly,  the Federal  National
                  Mortgage Association);

         (v)      collateralized  mortgage obligations issued by private issuers
                  for which the underlying mortgage-backed securities serving as
                  collateral  are  backed  by (i) the  credit  alone of the U.S.
                  Government   agency  or   instrumentality   which   issues  or
                  guarantees the  mortgage-backed  securities,  or (ii) the full
                  faith and credit of the U.S. Government; and

         (vi)     repurchase agreements collateralized by any of the foregoing.

Any  guarantee of the  securities  in which the Series  invests runs only to the
principal and interest payments on the securities and not to the market value of
such  securities  or to the principal  and interest  payments on the  underlying
mortgages.  A security  issued or  guaranteed  by a U.S.  Government  agency may
significantly  fluctuate in value, and the Series may not receive the originally
anticipated  yield on the  security.  Shares of the  Series  are not  insured or
guaranteed by the U.S. Government, its agencies or instrumentalities.

The sub-adviser seeks to add value by actively managing the portfolio's interest
rate  exposure,   yield  curve  positioning,   sector  allocation  and  security
selection.  In  selecting   mortgage-backed   securities  for  the  Series,  the
sub-adviser  determines a security's  average maturity and duration according to
mathematical  models that reflect certain  payment  assumptions and estimates of
future economic factors.  These estimates may vary from actual results,  and the

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market  risk.  Because  the  Series  invests  in  fixed-income
                  securities  of U.S.  and  foreign  issuers,  it is  subject to
                  market risk. For bonds,  market risk generally reflects credit
                  risk and  interest  rate  risk.  Credit  risk is the actual or
                  perceived  risk  that the  issuer of the bond will not pay the
                  interest and principal payments when due. Bond value typically
                  declines if the issuer's credit quality deteriorates. Interest
                  rate risk is the risk that  interest  rates  will rise and the
                  value of bonds, including those held by the Series, will fall.
                  A  broad-based  market  drop may also cause a bond's  price to
                  fall.

         o        Prepayment  risk.  During periods of falling  interest  rates,
                  there  is the risk  that a debt  security  with a high  stated
                  interest  rate will be prepaid  before its  expected  maturity
                  date.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.

investing in the Series with the cost of investing in other mutual funds.  Also,

future  performance  of the Series.  The example  also  assumes  that the Series
operating expenses remain the same.  Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

T. Rowe Price/JNL Established Growth Series

Investment  Objective.  The  investment  objective  of  the  T.  Rowe  Price/JNL
Established Growth Series is long-term growth of capital and increasing dividend
income.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing   primarily  in  a   diversified   portfolio   of  common   stocks  of
well-established  U.S. growth  companies.  A growth company is one which (i) has
demonstrated  historical  growth of earnings faster than the growth of inflation
and the economy in general,  and (ii) has  indications of being able to continue
this growth pattern in the  future.While  the Series will invest  principally in
U.S.  companies,  a substantial portion of the Series' assets can be invested in
foreign stocks.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series  invests  primarily in equity
                  securities,  it is subject to stock market risk.  Stock prices
                  typically  fluctuate  more than the  values of other  types of
                  securities, typically in response to changes in the particular
                  company's financial condition and factors affecting the market
                  in general.  For example,  unfavorable or  unanticipated  poor
                  earnings performance of the company may result in a decline in
                  its  stock's  price,  and a  broad-based  market drop may also
                  cause a stock's price to fall.  Growth investing risk.  Growth
                  companies  usually  invest a high portion of earnings in their
                  businesses,  and may lack the  dividends  of value stocks that
                  can  cushion  prices  in  a  falling  market.  Also,  earnings
                  disappointments often lead to sharp declines in prices because
                  investors  buy  growth  stocks  in  anticipation  of  superior
                  earnings growth.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both

T. Rowe Price/JNL Mid-Cap Growth Series

Investment Objective.  The investment objective of the T. Rowe Price/JNL Mid-Cap
Growth Series is long-term growth of capital.

Principal  Investment  Strategies.  The Series seeks to achieve its objective by
investing at least 65% of its total assets,  under normal market conditions in a
diversified portfolio of common stocks of medium-sized  (mid-cap) U.S. companies
which the  sub-adviser  believes have the potential for  above-average  earnings
growth.  The  sub-adviser  defines  mid-cap  companies  as  those  whose  market
capitalization,  at the time of  acquisition  by the  Series,  falls  within the
capitalization  range of companies in the S&P MidCap 400 Index.  The sub-adviser
relies on its proprietary research to identify mid-cap companies with attractive
growth  prospects.  The Series seeks to invest  primarily in companies that: (i)
offer  proven  products or services;  (ii) have a historical  record of earnings
growth  that is above  average;  (iii)  demonstrate  the  potential  to  sustain
earnings  growth;  (iv) operate in industries  experiencing  increasing  demand;
and/or (v) the sub-adviser believes are undervalued in the marketplace. However,
the Series will not  automatically  sell or cease to purchase stock of a company
it already owns just because the company's market  capitalization grows or falls
outside this range.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series invests in equity securities,

                  typically in response to changes in the  particular  company's
                  financial  condition  and  factors  affecting  the  market  in

                  earnings performance of the company may result in a decline in
                  its  stock's  price,  and a  broad-based  market drop may also

                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.

Stocks of mid-cap  companies  entail  greater risk and are usually more volatile
than shares of larger  companies.  In addition,  the  performance  of the Series
depends on the  sub-adviser's  ability to  effectively  implement the investment
strategies of the Series.

Performance.  The bar chart and table  below  show the past  performance  of the
Series' shares.  The chart presents the annual returns and shows how performance
has varied from year to year.  The table shows the  Series'  annual  returns and
compares them to a broad based index since these shares were first offered. Both
the chart and the table assume reinvestment of dividends and distributions.  The
Series'  returns shown in the chart and table below do not reflect the deduction
of any  charges  that are imposed  under a variable  insurance  contract.  Those
charges,  which are described in the variable insurance prospectus,  will reduce
the Series' performance.  As with all mutual funds, the Series' past performance
does not necessarily indicate how it will perform in the future.

* As discussed  under  "Management  of the Trust," the  Trustees  have adopted a
Brokerage  Enhancement  Plan (the "Plan") in accordance  with the  provisions of
Rule 12b-1 under the Investment Company Act of 1940. The Plan uses the available
brokerage  commissions  to promote  the sale of shares of the  Trust.  While the
brokerage  commission  rates and amounts  paid by the Trust are not  expected to
increase as a result of the  Distribution  Plan, the staff of the Securities and
Exchange  Commission  has taken the position that  commission  amounts  received
under the Distribution Plan should be reflected as distribution  expenses of the
Series.  The  distribution  fee noted is an  estimate  and  therefore  it is not
possible to determine with accuracy  actual amounts that will be received by the
Series under the Plan.


Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the Series.  The T. Rowe  Price/JNL  Mid-Cap Growth Series seeks to
achieve its objective of long-term  growth of capital by investing  primarily in
common stocks of U.S. companies with medium-sized market capitalizations and the
potential  for  above-average  growth.  The Series may also invest in securities
other  than  U.S.  common  stocks,  including  foreign  securities,  convertible
securities,  and warrants.  The Series may use derivative  instruments,  such as
options  and futures  contracts,  for hedging  purposes  and to maintain  market
exposure.  These instruments are subject to transaction costs and certain risks,
such as unanticipated  changes in securities  prices. If the Series uses futures
and options, it is exposed to additional volatility and potential losses.

The  Series may sell  securities  for a variety  of  reasons,  such as to secure
gains, limit losses, or redeploy assets into more promising opportunities.

The SAI has more  information  about  the  Series'  authorized  investments  and
strategies, as well as the risks and restrictions that may apply to them.

The  Sub-Adviser  and  Portfolio  Management.  The  sub-adviser  to the T.  Rowe
Price/JNL  Mid-Cap  Growth Series is T. Rowe Price  Associates,  Inc. (T. Rowe),
located at 100 East Pratt Street, Baltimore, Maryland 21202. T. Rowe was founded
in 1937. T. Rowe and its  affiliates  provide  investment  advisory  services to
individual and institutional investor accounts.

The  Series has an  Investment  Advisory  Committee  composed  of the  following
members: Brian W. Berghuis,  Chairman,  James A.C. Kennedy, and John F. Wakeman.
The Committee Chairman has day to day responsibility for managing the Series and
works with the  Committee in developing  and  executing  the Series'  investment
program.  Mr.  Berghuis,  a  Managing  Director  of T. Rowe,  has been  managing
investments since joining T. Rowe in 1985. The Investment Advisory Committee has
had day-to-day responsibility for managing the Series since the inception of the
Series.

T. Rowe Price/JNL Value Series

Investment  Objective.  The investment  objective of the T. Rowe Price/JNL Value
Series is to provide  long-term  capital  appreciation  by  investing  in common
stocks believed to be undervalued. Income is a secondary objective.

Principal  Investment  Strategies.  In  taking a value  approach  to  investment
selection,  at least 65% of total  assets will be invested in common  stocks the
portfolio manager regards as undervalued. Stock holdings are expected to consist
primarily of large-company  issues, but may also include smaller  companies.  In
selecting investments, the sub-adviser generally looks for the following:

         o        low  price/earnings,  price/book  value,  or  price/cash  flow
                  ratios relative to the S&P 500 Index,  the company's peers, or
                  its own historic norm;

         o        low stock  price  relative  to a  company's  underlying  asset
                  values;

         o        a plan to improve the business through restructuring; and

         o        a  sound   balance   sheet   and  other   positive   financial
                  characteristics.

Principal  Risks of Investing in the Series.  An investment in the Series is not
guaranteed. As with any mutual fund, the value of the Series' shares will change
and you could lose money by  investing  in the Series.  A variety of factors may
influence its investment performance, such as:

         o        Market risk.  Because the Series invests in stocks of U.S. and
                  foreign  companies,  it is subject to stock market risk. Stock
                  prices typically fluctuate more than the values of other types
                  of  securities,  typically  in  response  to  changes  in  the
                  particular company's financial condition and factors affecting
                  the  market  in   general.   For   example,   unfavorable   or
                  unanticipated  poor  earnings  performance  of the company may
                  result in a decline in its stock's  price,  and a  broad-based
                  market drop may also cause a stock's price to fall.  Investing
                  in small- and medium-company stocks generally involves greater
                  risks than investing in larger, more established ones.

         o        Value investing risk. The value approach carries the risk that
                  the market will not recognize a security's intrinsic value for
                  a long  time,  or that a stock  judged to be  undervalued  may
                  actually be appropriately priced.

         o        Foreign investing risk.  Foreign investing  involves risks not
                  typically  associated  with  U.S.   investment.   These  risks
                  include,   among  others,   adverse  fluctuations  in  foreign
                  currency  values  as well as  adverse  political,  social  and
                  economic   developments   affecting  a  foreign  country.   In
                  addition,  foreign investing  involves less publicly available
                  information   and  more  volatile  or  less  liquid   markets.
                  Investments in foreign  countries could be affected by factors
                  not present in the U.S., such as restrictions on receiving the
                  investment proceeds from a foreign country,  foreign tax laws,
                  and   potential    difficulties   in   enforcing   contractual
                  obligations. Transactions in foreign securities may be subject
                  to less efficient  settlement  practices,  including  extended
                  clearance and settlement  periods.  Foreign  accounting may be
                  less revealing  than American  accounting  practices.  Foreign
                  regulation  may be  inadequate or  irregular.  Owning  foreign
                  securities  could cause the Series'  performance  to fluctuate
                  more than if it held only U.S. securities.

         o        Derivatives risk. Investing in derivative instruments, such as
                  options,   futures  contracts,   forward  currency  contracts,
                  indexed  securities  and  asset-backed  securities,   involves
                  special risks. The Series  sub-adviser must correctly  predict
                  price  movements,  during  the  life of a  derivative,  of the
                  underlying  asset in order to realize the desired results from
                  the investment. The value of derivatives may rise or fall more
                  rapidly  than  other  investments,   which  may  increase  the
                  volatility of the Series depending on the nature and extent of
                  the derivatives in the Series'  portfolio.  If the sub-adviser
                  uses  derivatives  in  attempting  to  manage or  "hedge"  the
                  overall  risk of the  portfolio,  the  strategy  might  not be
                  successful,  for  example,  due to changes in the value of the
                  derivatives  that do not correlate with price movements in the
                  rest of the portfolio.

         o        Currency risk. The value of the Series' shares may change as a
                  result of changes in exchange  rates reducing the value of the
                  U.S. dollar value of the Series' foreign investments. Currency
                  exchange  rates can be  volatile  and  affected by a number of
                  factors,  such as the  general  economics  of a  country,  the
                  actions of U.S. and foreign  governments or central banks, the
                  imposition of currency controls, and speculation.

In addition,  the performance of the Series depends on the sub-adviser's ability
to effectively implement the investment strategies of the Series.

COMPARABLE PERFORMANCE

Public Fund Performance

The  T.  Rowe  Price/JNL  Value  Series  has  substantially  similar  investment
objectives,  policies and  investment  strategies as certain  mutual funds whose
shares are sold to the public.  The T. Rowe Price Value Fund is a public  mutual
fund  managed by T. Rowe Price  Associates,  Inc.,  the same  Sub-Adviser  which
manages each of the corresponding Series.

The historical  performance of the T. Rowe Price Value Fund is shown below. This
performance data should not be considered as an indication of future performance
of the Series. The public mutual fund performance figures shown below:

         o        reflects the historical  fees and expenses paid by the T. Rowe
                  Value Fund and not those paid by the Series.

         o        do not  reflect  Contract  fees or charges  imposed by Jackson
                  National Life.  Investors should refer to the separate account
                  prospectus  for  information  describing the Contract fees and
                  charges. These fees and charges will have a detrimental effect
                  on Series performance.

The Series and their  corresponding  public  mutual fund series are  expected to
hold  similar  securities.  However,  their  investment  results are expected to
differ for the following reasons:

         o        differences  in  asset  size  and  cash  flow  resulting  from
                  purchases  and  redemptions  of Series  shares  may  result in
                  different security selections

o differences in the relative weightings of securities

o differences in the price paid for particular portfolio holdings

o differences relating to certain tax matters

However,  the differences  cited do not alter the conclusion that the Funds have
substantially similar investment objectives, policies and strategies.

(1) Source: T. Rowe Price  Associates,  Inc. Total returns were calculated using
the actual fees and expenses of the T. Rowe Value Fund.  These fees and expenses
are less than the fees charged by the Series. The performance returns would have
been lower if the actual  expenses of the Series had been used. The returns were
calculated using the  standardized  Securities and Exchange  Commission  method.
Actual  account  performance  will vary depending on the size of a portfolio and
applicable fee schedule. Performance figures are based on historical performance
and do not guarantee future results.  Performance for the T. Rowe Price/JNL Vale

in any one  market  capitalization  range  over an  extended  period of time.  A
Series'  performance  may be  affected  by risks  specific  to certain  types of
investments, such as foreign securities, derivative investments,  non-investment
grade  debt  securities,  initial  public  offerings  (IPOs) or  companies  with
relatively small market  capitalizations.  IPOs and other investment  techniques
may have  magnified  performance  impact on a Series with a small asset base.  A
Series may not experience similar performance as its assets grow.

Additional Information About the Other Investment Strategies,  Other Investments
and Risks of the  Series.  The  Series  may sell  securities  for a  variety  of
reasons,  such as to secure gains,  limit losses,  or redeploy  assets into more
promising opportunities.

The Series  may invest up to 25% of its total  assets  (excluding  reserves)  in
foreign securities.  Although the Series will invest primarily in common stocks,
the Series may invest in any type of security or instrument  (including  certain
potentially   high-risk   derivatives)  whose  investment   characteristics  are
consistent with the Series' investment program. These may include:

         o        preferred stocks

         o        convertible securities and warrants

         o        fixed income securities,  including lower quality (high-yield,
                  high-risk bonds) commonly referred to as "junk bonds"

         o        hybrid  instruments  which  combine  the   characteristics  of
                  securities, futures and options

         o        private placements

If the Series uses futures and options,  it is exposed to additional  volatility
and potential  losses.The SAI has more information about the Series'  authorized
investments and strategies.

Sub-Advisory Arrangements

JNFS  selects,  contracts  with  and  compensates  sub-advisers  to  manage  the
investment  and  reinvestment  of the assets of the  Series of the  Trust.  JNFS
monitors the compliance of such sub-advisers with the investment  objectives and
related policies of each Series and reviews the performance of such sub-advisers
and reports periodically on such performance to the Trustees of the Trust.

Under  the  terms  of  each  of  the  Sub-Advisory  Agreements  with  JNFS,  the
sub-adviser  manages  the  investment  and  reinvestment  of the  assets  of the
assigned  Series,  subject to the supervision of the Trustees of the Trust.  The
sub-adviser  formulates  a  continuous  investment  program for each such Series
consistent  with  its  investment  objectives  and  policies  outlined  in  this
Prospectus.  Each sub-adviser implements such programs by purchases and sales of
securities  and  regularly  reports to JNFS and the  Trustees  of the Trust with
respect to the implementation of such programs.

As  compensation  for its services,  each  sub-adviser  receives a fee from JNFS
computed separately for the applicable Series, stated as an annual percentage of
the net assets of such  Series.  The SAI  contains a schedule of the  management
fees JNFS currently is obligated to pay the sub-advisers out of the advisory fee
it receives from the Series.


The  Investment  Adviser  and the Trust has  filed an  application  to obtain an
exemption  from the  Securities  and  Exchange  Commission  for a  multi-manager
structure  that  allows the  Investment  Adviser to hire,  replace or  terminate
sub-advisers  without the approval of  shareholders.  The order would also allow
the Investment  Adviser to revise a sub-advisory  agreement with the approval of
the Board of Trustees, but without shareholder approval. If a new sub-adviser is
hired, shareholders will receive information about the new sub-adviser within 90
days of the change. The order would allow the Series to operate more efficiently
and with greater  flexibility.  The  Investment  Adviser  provides the following
oversight and evaluation services to the Series:

         o        performing  initial due diligence on prospective  sub-advisers
                  for the Series
         o        monitoring the performance of sub-advisers
         o        communicating performance expectations to the sub-advisers
         o        ultimately  recommending  to the Board of  Trustees  whether a
                  sub-adviser's   contract   should  be  renewed,   modified  or
                  terminated.

The  Investment  Adviser  does not  expect  to  recommend  frequent  changes  of
sub-advisers.  Although the Investment  Adviser will monitor the  performance of
the  sub-advisers,  there is no certainty  that any  sub-adviser  or Series will
obtain favorable results at any given time.


                               ADMINISTRATIVE FEE

In  addition  to the  investment  advisory  fee,  each  Series,  except  the JNL
International   Index   Series  and  the  JNL/S&P   Series,   pays  to  JNFS  an
Administrative  Fee of .10% of the average  daily net assets of the Series.  The
JNL International  Index Series pays an Administrative  Fee of .15%. The JNL/S&P
Series do not pay an Administrative Fee. In return for the fee, JNFS provides or
procures all necessary  administrative  functions and services for the operation
of the Series. In addition, JNFS, at its own expense, arranges for legal, audit,
fund accounting, custody, printing and mailing, and all other services necessary
for the  operation  of each  Series.  Each  Series is  responsible  for  trading
expenses  including  brokerage  commissions,   interest  and  taxes,  and  other
non-operating expenses.


                           BROKERAGE ENHANCEMENT PLAN

Certain  Series of the Trust has adopted,  in accordance  with the provisions of
Rule 12b-1 under the  Investment  Company Act of 1940,  a Brokerage  Enhancement
Plan (the "Plan"). The Plan uses available brokerage  commissions to promote the
sale and  distribution of Trust shares  (through the sale of variable  insurance
products funded by the Trust).

Under the Plan, the Trust may direct the Investment  Adviser or a sub-adviser to
use certain broker-dealers for securities transactions.  (The duty of best price
and execution  still applies to these  transactions.)  These are  broker-dealers
that have agreed either (1) to pay a portion of their  commission  from the sale
and  purchase  of  securities  to the  series  which  will then be passed to the
Distributor  or other  introducing  brokers  ("Brokerage  Payments"),  or (2) to
provide  brokerage  credits,  benefits or services  ("Brokerage  Credits").  The
Distributor  will use all Brokerage  Payments and Credits  (other than a minimal
amount to defray its legal and administrative  costs) to finance activities that
are meant to result in the sale of the Trust's shares, including:

         o        holding  or  participating  in  seminars  and  sales  meetings
                  promoting the sale of the Trust's shares
         o        paying marketing fees requested by broker-dealers who sell the
                  variable insurance products
         o        training sales personnel
         o        creating and mailing advertising and sales literature
         o        financing any other activity that is intended to result in the
                  sale of Trust's shares.

The Plan  permits the  Brokerage  Payments and Credits  generated by  securities
transactions  from one  series  of the  Trust to inure to the  benefit  of other
Series as well. The Plan is not expected to increase the brokerage  costs of the
Trust.  For  more  information  about  the  Plan,  please  read  the  "Brokerage
Enhancement Plan" section of the Statement of Additional Information.


                           INVESTMENT IN TRUST SHARES


Shares  of the Trust are  currently  sold to  separate  accounts  (Accounts)  of
Jackson  National Life Insurance  Company,  1 Corporate Way,  Lansing,  Michigan
48951, and Jackson National Life Insurance Company of New York, 2900 Westchester
Avenue,  Purchase,  New York 10577, to fund the benefits under certain  variable
annuity  contracts  (Contracts) and to qualified  retirement plans. An insurance
company  purchases  the  shares of the  Series at their  net asset  value  using
premiums  received on Contracts  issued by the  insurance  company.  There is no
sales charge.


Shares of the Series are not available to the general public  directly.  Some of
the Series are managed by  sub-advisers  who manage publicly traded mutual funds
having similar names and investment objectives.  While some of the Series may be
similar  to, and may in fact be modeled  after  publicly  traded  mutual  funds,
Contract purchasers should understand that the Series are not otherwise directly
related  to any  publicly  traded  mutual  fund.  Consequently,  the  investment
performance  of publicly  traded mutual funds and any  corresponding  Series may
differ substantially.

The net  asset  value per share of each  Series  is  determined  at the close of
regular  trading on the New York Stock  Exchange  (normally  4:00 p.m.,  Eastern
time) each day that the New York Stock Exchange is open. The net asset value per
share is calculated by adding the value of all  securities and other assets of a
Series,  deducting  its  liabilities,  and  dividing  by the  number  of  shares
outstanding.  Generally,  the value of  exchange-listed or -traded securities is
based on their  respective  market  prices,  bonds  are  valued  based on prices
provided by an independent  pricing  service and short-term  debt securities are
valued at amortized cost, which  approximates  market value. A Series may invest
in securities  primarily listed on foreign exchanges and that trade on days when
the Series does not price its shares. As a result, a Series' net asset value may
change on days when  shareholders are not able to purchase or redeem the Series'
shares.

All  investments in the Trust are credited to the  shareholder's  account in the
form of full and  fractional  shares of the  designated  Series  (rounded to the
nearest 1/1000 of a share). The Trust does not issue share certificates.

                                SHARE REDEMPTION

An Account redeems shares to make benefit or withdrawal payments under the terms
of its  Contracts.  Redemptions  are  processed on any day on which the Trust is
open for business and are effected at net asset value next determined  after the
redemption order, in proper form, is received by the Trust's transfer agent.

The Trust may suspend the right of redemption  only under the following  unusual
circumstances:

         o        when  the New  York  Stock  Exchange  is  closed  (other  than
                  weekends and holidays) or trading is restricted;

         o        when  an  emergency  exists,   making  disposal  of  portfolio
                  securities  or the  valuation  of net  assets  not  reasonably
                  practicable; or

         o        during  any  period  when  the SEC has by  order  permitted  a
                  suspension of redemption for the protection of shareholders.

                                   TAX STATUS

Each Series' policy is to meet the  requirements of Subchapter M of the Internal
Revenue Code (Code) necessary to qualify as a regulated investment company. Each
Series intends to distribute all its net investment income and net capital gains
to shareholders and,  therefore,  will not be required to pay any federal income
taxes.

Each  Series is treated  as a separate  corporation  for  purposes  of the Code.
Therefore,  the assets,  income, and distributions of each Series are considered
separately for purposes of determining  whether or not the Series qualifies as a
regulated investment company.

Because the  shareholders  of each Series are Accounts and qualified  retirement
plans,  there  are no tax  consequences  to  shareholders  of  buying,  holding,
exchanging and selling shares of the Series.  Distributions  from the Series are
not taxable to those shareholders.  However,  owners of Contracts should consult
the applicable  Account  prospectus for more detailed  information on tax issues
related to the Contracts.

                         GENERAL INFORMATION AND HISTORY

         The JNL Series Trust (the "Trust") is an open-end management investment
company  organized  under the laws of the  Commonwealth of  Massachusetts,  by a
Declaration  of Trust dated June 1, 1994.  The Trust  offers  shares in separate
Series, each with its own investment objective.

              COMMON TYPES OF INVESTMENTS AND MANAGEMENT PRACTICES

         This  section  describes  some of the types of  securities a Series may
hold in its portfolio and the various kinds of investment  practices that may be
used in day-to-day  portfolio  management.  A Series may invest in the following
securities  or  engage  in the  following  practices  to the  extent  that  such
securities and practices are consistent with the Series' investment objective(s)
and policies described in the Prospectus and in this SAI.

Asset-Backed Securities.  A Series may invest in asset-backed securities,  which
include mortgage-backed securities.  Asset-backed securities represent interests
in pools of consumer loans and most are structured as  pass-through  securities.
The credit  quality of most  asset-backed  securities  depends  primarily on the
credit quality of the assets  underlying  such  securities,  how well the entity
issuing the security is insulated  from the credit risk of the originator or any
other  affiliated  entities,  and the amount and  quality of any credit  support
provided  to the  securities.  The rate of  principal  payment  on  asset-backed
securities  generally depends on the rate of principal  payments received on the
underlying  assets,  which in turn may be affected by a variety of economic  and
other factors. As a result, the yield on any asset-backed  security is difficult
to predict with  precision and actual yield to maturity may be more or less than
the anticipated yield to maturity. A sub-adviser  considers estimated prepayment
rates in calculating the average weighted maturities of the Series.  Unscheduled
prepayments are more likely to accelerate during periods of declining  long-term
interest  rates.  In the  event of a  prepayment  during a period  of  declining
interest rates, a Series may be required to invest the unanticipated proceeds at
a lower interest rate. Prepayments during such periods will also limit a Series'
ability to participate  in as large a market gain as may be  experienced  with a
comparable security not subject to prepayment.

         Asset-backed securities may be classified as pass-through  certificates
or  collateralized  obligations.   Pass-through  certificates  are  asset-backed
securities  that  represent an  undivided  fractional  ownership  interest in an
underlying  pool  of  assets.  Pass-through  certificates  usually  provide  for
payments  of  principal  and  interest  received  to be passed  through to their
holders,  usually after  deduction  for certain  costs and expenses  incurred in
administering the pool. Because pass-through certificates represent an ownership
interest in the underlying assets, the holders thereof directly bear the risk of
any defaults by the obligors on the underlying  assets not covered by any credit
support.

         Asset-backed  securities issued in the form of debt  instruments,  also
known as  collateralized  obligations,  are  generally  issued  as the debt of a
special  purpose entity  organized  solely for the purpose of owning such assets
and  issuing  such  debt.  Such  assets  are most often  trade,  credit  card or
automobile receivables.  The assets collateralizing such asset-backed securities
are pledged to a trustee or  custodian  for the  benefit of the holders  hereof.
Such  issuers   generally  hold  no  assets  other  than  those  underlying  the
asset-backed  securities and any credit support provided. As a result,  although
payments on such asset-backed  securities are obligations of the issuers, in the
event of defaults on the  underlying  assets not covered by any credit  support,
the issuing  entities are unlikely to have  sufficient  assets to satisfy  their
obligations on the related asset-backed securities.

Bank  Obligations.  A Series  may  invest  in bank  obligations,  which  include
certificates  of  deposit,  bankers'  acceptances,  and  other  short-term  debt
obligations.  Certificates  of deposit are short-term  obligations of commercial
banks.  A bankers'  acceptance  is a time draft drawn on a commercial  bank by a
borrower,  usually in connection  with  international  commercial  transactions.
Certificates of deposit may have fixed or variable rates.  The Series may invest
in U.S. banks,  foreign branches of U.S. banks,  U.S. branches of foreign banks,
and foreign branches of foreign banks.

Borrowing  and Lending.  A Series may borrow  money from banks for  temporary or
emergency  purposes  in  amounts  up to 25%  of  its  total  assets.  To  secure
borrowings,  a Series may mortgage or pledge  securities in amounts up to 15% of
its net assets.

Cash Position.  A Series may hold a certain  portion of its assets in repurchase
agreements  and money  market  securities  maturing in one year or less that are
rated in one of the two highest  rating  categories  by a nationally  recognized
statistical rating organization. For temporary, defensive purposes, a Series may
invest without  limitation in such securities.  This reserve  position  provides
flexibility in meeting redemptions, expenses, and the timing of new investments,
and serves as a short-term defense during periods of unusual market volatility.

Collateralized  Mortgage  Obligations (CMOs). A Series may invest in CMOs, which
are  bonds  that  are   collateralized  by  whole  loan  mortgages  or  mortgage
pass-through securities.  The bonds issued in a CMO transaction are divided into
groups,  and each  group  of bonds is  referred  to as a  "tranche."  Under  the
traditional CMO structure, the cash flows generated by the mortgages or mortgage
pass-through  securities in the  collateral  pool are used to first pay interest
and then pay  principal  to the CMO  bondholders.  The bonds  issued under a CMO
structure  are  retired  sequentially  as  opposed  to the pro  rata  return  of
principal found in traditional pass-through obligations.  Subject to the various
provisions of individual  CMO issues,  the cash flow generated by the underlying
collateral  (to the extent it  exceeds  the  amount  required  to pay the stated
interest) is used to retire the bonds. Under the CMO structure, the repayment of
principal  among the different  tranches is prioritized  in accordance  with the
terms of the particular CMO issuance.  The  "fastest-pay"  tranche of bonds,  as
specified in the prospectus for the issue, would initially receive all principal
payments.  When that tranche of bonds is retired, the next tranche, or tranches,
in the sequence,  as specified in the  prospectus,  receive all of the principal
payments  until they are  retired.  The  sequential  retirement  of bonds groups
continues until the last tranche,  or group of bonds,  is retired.  Accordingly,
the CMO  structure  allows  the  issuer  to use  cash  flows  of long  maturity,
monthly-pay collateral to formulate securities with short, intermediate and long
final  maturities and expected  average lives.  Depending on the type of CMOs in
which the Series  invests,  the investment may be subject to a greater or lesser
risk of prepayment than other types of mortgage-related securities.

         The primary risk of any  mortgage  security is the  uncertainty  of the
timing of cash  flows.  For CMOs,  the  primary  risk  results  from the rate of
prepayments on the underlying  mortgages  serving as collateral.  An increase or
decrease in prepayment rates (resulting primarily from a decrease or increase in
mortgage interest rates) will affect the yield, average life, and price of CMOs.
The  prices  of  certain  CMOs,  depending  on their  structure  and the rate of
prepayments,  can be  volatile.  Some  CMOs may also not be as  liquid  as other
securities.

Commercial Paper. A Series may invest in commercial paper.  Commercial paper are
short-term  promissory  notes  issued  by  corporations   primarily  to  finance
short-term credit needs. Certain notes may have floating or variable rates.

Common and  Preferred  Stocks.  A Series may invest in common  and/or  preferred
stocks. Stocks represent shares of ownership in a company. Generally,  preferred
stock has a specified dividend and ranks after bonds and before common stocks in
its claim on income for dividend  payments  and on assets  should the company be
liquidated. After other claims are satisfied, common stockholders participate in
company  profits on a pro rata basis;  profits may be paid out in  dividends  or
reinvested  in the company to help it grow.  Increases and decreases in earnings
are usually  reflected in a company's  stock price,  so common stocks  generally
have the greatest  appreciation  and  depreciation  potential  of all  corporate
securities.  While most preferred  stocks pay a dividend,  a Series may purchase
preferred  stock  where the issuer  has  omitted,  or is in danger of  omitting,
payment of its  dividend.  Such  investments  would be made  primarily for their
capital  appreciation  potential.  Although  common and preferred  stocks have a
history of  long-term  growth in value,  their  prices tend to  fluctuate in the
short term, particularly those of smaller companies.

Convertible  Securities  and Warrants.  A Series may invest in debt or preferred
equity  securities  convertible  into or  exchangeable  for  equity  securities.
Traditionally,  convertible  securities have paid dividends or interest at rates
higher  than  common  stocks but lower  than  non-convertible  securities.  They
generally  participate in the  appreciation  or  depreciation  of the underlying
stock into which they are convertible,  but to a lesser degree. In recent years,
convertibles  have been  developed  which combine higher or lower current income
with options and other features.  Warrants are options to buy a stated number of
shares of common  stock at a  specified  price any time  during  the life of the
warrants (generally, two or more years).

Catastrophe  Bonds.  Catastrophe bonds are fixed income securities for which the
return of principal and payment of interest is contingent on the  non-occurrence
of a specific trigger event, such as a hurricane or an earthquake.  If a trigger
event causes losses  exceeding a specific  amount in the  geographic  region and
time  period  specified  in a bond,  a Series  investing  in the bond may lose a
portion  or all of its  principal  invested  in the bond.  If no  trigger  event
occurs,  the Series will recover its principal plus interest.  Catastrophe bonds
may also expose the Series to certain  unanticipated  risks  including,  but not
limited to,  issuer  (credit)  default,  adverse  regulatory  or  jurisdictional
interpretation, and adverse tax consequences.

Diversification.  Certain of the Series are diversified companies,  as such term
is defined  under the  Investment  Company  Act of 1940,  as amended  (the "1940
Act").  A Series that is a  diversified  company under the 1940 Act will have at
least 75% of the value of its total assets represented by:

o        cash and cash items (including receivables),
o        Government securities,
o        securities of other investment companies, and
o        other securities  limited in respect to any one issuer to not more than
         5% of the value of the Series' total assets and to not more than 10% of
         the outstanding voting securities of such issuer.

         These  percentage  limitations  are  measured at the time that a Series
acquires a security,  and a Series will not lose its  diversification  status if
the  Series'  holdings  exceed  these  percentages  because of  post-acquisition
changes in security prices.

Equity Swaps.  Equity swap contracts  offer an opportunity to invest in a market
without  owning or taking  physical  custody of securities in  circumstances  in
which  direct  investment  is  restricted  for  legal  reasons  or is  otherwise
impracticable.  The  counterparty to an equity swap contract will typically be a
bank, investment banking firm or broker/dealer.  The counterparty will generally
agree to pay the Series the amount,  if any, by which the notional amount of the
equity swap contract  would have  increased in value had it been invested in the
particular  stocks,  plus the  dividends  that would have been received on those
stocks.  The Series  will agree to pay to the  counterparty  a floating  rate of
interest on the notional amount of the equity swap contract plus the amount,  if
any, by which that  notional  amount  would have  decreased in value had it been
invested in such stocks.  Therefore, the return to the Series on any equity swap
contract should be the gain or loss on the notional amount plus dividends on the
stocks less the interest paid by the Series on the notional amount.

         The  Series  will enter into  equity  swaps only on a net basis,  which
means that the two payment streams are netted out, with the Series  receiving or
paying,  as the case may be, only the net amount of the two  payments.  Payments
may be made at the conclusion of an equity swap contract or periodically  during
its term.  Equity  swaps do not involve  the  delivery  of  securities  or other
underlying assets. Accordingly, the risk of loss with respect to equity swaps is
limited to the net amount of  payments  that is  contractually  obligated  to be
made.  If the other party to an equity swap  defaults,  the Series' risk of loss
consists  of the net  amount  of  payments  that such  Series  is  contractually
entitled  to  receive,  if any.  The net amount of the  excess,  if any,  of the
Series'  obligations over its entitlements with respect to each equity swap will
be accrued on a daily  basis and an amount of cash or liquid  assets,  having an
aggregate  net  asset  value  at  least  equal to such  accrued  excess  will be
maintained in a segregated account by the Series'  custodian.  Inasmuch as these
transactions  are entered into for hedging  purposes or are offset by segregated
cash or liquid assets, as permitted by applicable law, the Series will not treat
them as being subject to the Series' borrowing restrictions.

Fixed-Income  Securities.  A Series may  invest in  fixed-income  securities  of
companies  which  meet the  investment  criteria  for the  Series.  The price of
fixed-income  securities  fluctuates with changes in interest  rates,  generally
rising when interest rates fall and falling when interest rates rise.  Prices of
longer-term securities generally increase or decrease more sharply than those of
shorter-term securities in response to interest rate changes.

Foreign  Currency  Transactions.  A Series  will  normally  conduct  its foreign
currency exchange  transactions either on a spot (i.e., cash), basis at the spot
rate prevailing in the foreign  currency  exchange  market,  or through entering
into forward  contracts to purchase or sell  foreign  currencies.  A Series will
generally  not enter into a forward  contract  with a term of  greater  than one
year.

         There  are  certain  markets  where it is not  possible  to  engage  in
effective  foreign  currency  hedging.  This may be true,  for example,  for the
currencies  of various  countries  where the  foreign  exchange  markets are not
sufficiently developed to permit hedging activity to take place.

Foreign Securities. A Series may invest in foreign securities.  Investors should
realize  that  investing  in  foreign   securities   involves   certain  special
considerations  which  are  not  typically  associated  with  investing  in U.S.
securities.   These  include  non-U.S.   dollar-denominated   securities  traded
principally  outside the U.S. and U.S.  dollar-denominated  securities traded in
the U.S. (such as American  Depositary  Receipts).  Such investments  increase a
Series'  diversification  and may enhance  return,  but they also  involve  some
special  risks such as exposure  to  potentially  adverse  local  political  and
economic developments;  nationalization and exchange controls; potentially lower
liquidity and higher  volatility;  possible  problems  arising from  accounting,
disclosure,   settlement,   and  regulatory  practices  that  differ  from  U.S.
standards;  and the chance  that  fluctuations  in foreign  exchange  rates will
decrease the investment's  value (favorable  changes can increase its value). In
addition,  foreign securities purchased by the Series, may be subject to foreign
government  taxes,  higher  custodian  fees,  higher  brokerage  commissions and
dividend collection fees. Foreign government securities are issued or guaranteed
by a foreign government,  province,  instrumentality,  political  subdivision or
similar unit thereof.

Futures and Options.  Futures  contracts are often used to manage risk,  because
they enable the investor to buy or sell an asset in the future at an agreed upon
price.  Options give the investor the right,  but not the obligation,  to buy or
sell an asset at a predetermined  price in the future. A Series may buy and sell
futures  contracts  (and  options on such  contracts)  to manage its exposure to
changes in securities prices and foreign currencies and as an efficient means of
adjusting  overall  exposure to certain  markets.  A Series may purchase or sell
call and put options on securities,  financial indices,  and foreign currencies,
and may invest in futures contracts on foreign currencies and financial indices,
including  interest  rates or an index of U.S.  Government  securities,  foreign
government securities or equity or fixed-income securities.

         Futures  contracts  and  options may not always be  successful  hedges;
their  prices can be highly  volatile;  using them could  lower a Series'  total
return;  and the  potential  loss from the use of futures can exceed the Series'
initial  investment in such  contracts.  These  instruments may also be used for
non-hedging purposes such as increasing a Series' income.

         The Series' use of  commodity  futures and  commodity  options  trading
should not be viewed as providing a vehicle for shareholder  participation  in a
commodity pool. Rather, in accordance with regulations  adopted by the Commodity
Futures Trading Commission (CFTC), a Series will employ such techniques only for
(1) hedging  purposes,  or (2) otherwise,  to the extent that aggregate  initial
margin and required premiums do not exceed 5 percent of the Series' net assets.

         Foreign  government  securities  are issued or  guaranteed by a foreign
government,  province,  instrumentality,  political  subdivision or similar unit
thereof.

High-Yield  Bonds.  A Series may invest  its assets in  fixed-income  securities
offering  high  current  income  that  are  in  the  lower-rated  categories  of
recognized  rating  agencies or, if not rated,  considered  to be of  comparable
quality. These lower-rated  fixed-income securities are considered,  on balance,
as predominantly  speculative with respect to capacity to pay interest and repay
principal in accordance  with the terms of the  obligation  and  generally  will
involve  more  credit  risk than  securities  in the  higher  rated  categories.
High-yield bonds are commonly referred to as "junk bonds."

         High-yield  securities  frequently  are issued by  corporations  in the
growth stage of their development.  They may also be issued in connection with a
corporate  reorganization  or a corporate  takeover.  Companies  that issue such
high-yielding  securities  often are highly leveraged and may not have available
to them more traditional  methods of financing.  Therefore,  the risk associated
with acquiring the  securities of such issuers  generally is greater than is the
case with higher rated securities.  For example,  during an economic downturn or
recession,  highly  leveraged  issuers of high-yield  securities  may experience
financial  stress.  During such  periods,  such issuers may not have  sufficient
revenues to meet their interest  payment  obligations.  The issuer's  ability to
service  its  debt  obligations  may  also be  adversely  affected  by  specific
corporate  developments,  or the issuer's  inability to meet specific  projected
business  forecasts,  or the  unavailability  of additional  financing.  Adverse
publicity and investor  perceptions  regarding lower rated bonds, whether or not
based upon fundamental analysis, may also depress the price for such securities.
The risk of loss from  default by the issuer is  significantly  greater  for the
holders of high-yield securities because such securities are generally unsecured
and are often subordinated to other creditors of the issuer.

Hybrid Instruments. A Series may purchase hybrid instruments,  which combine the
elements of futures contracts or options with those of debt, preferred equity or
a depository instrument. Often these hybrid instruments are indexed to the price
of a commodity,  a particular currency,  or a domestic or foreign debt or equity
securities index. Hybrid instruments may take a variety of forms, including, but
not  limited  to,  debt  instruments  with  interest  or  principal  payments or
redemption terms determined by reference to the value of a currency or commodity
or  securities  index at a future point in time,  preferred  stock with dividend
rates  determined  by  reference  to the  value of a  currency,  or  convertible
securities with the conversion terms related to a particular commodity.

Illiquid  Securities.   A  Series  may  hold  illiquid   investments.   Illiquid
investments are  investments  that cannot be sold or disposed of in the ordinary
course of business  within seven days at  approximately  the price at which they
are valued.  Illiquid investments  generally include:  repurchase agreements not
terminable  within seven days;  securities  for which market  quotations are not
readily  available;  restricted  securities  not  determined  to  be  liquid  in
accordance  with  guidelines  established  by the  Trust's  Board  of  Trustees;
over-the-counter  (OTC)  options  and, in certain  instances,  their  underlying
collateral; and securities involved in swap, cap, collar and floor transactions.

Inflation-Indexed   Bonds.  A  Series  may  purchase   inflation-indexed  bonds.
Inflation-indexed  bonds are fixed income  securities  whose  principal value is
periodically  adjusted according to the rate of inflation.  Such bonds generally
are issued at an interest  rate lower than  typical  bonds,  but are expected to
retain their  principal  value over time.  The  interest  rate on these bonds is
fixed at issuance,  but over the life of the bond the interest may be paid on an
increasing principal value, which has been adjusted for inflation.

         Inflation-indexed   securities   issued  by  the  U.S.   Treasury  have
maturities of ten years,  although it is anticipated  that securities with other
maturities  will be issued in the  future.  The  securities  pay  interest  on a
semi-annual  basis,  equal  to a  fixed  percentage  of  the  inflation-adjusted
principal amount.

         If  the  periodic   adjustment  rate  measuring  inflation  falls,  the
principal  value of  inflation-indexed  bonds  will be  adjusted  downward,  and
consequently the interest  payable on these securities  (calculated with respect
to a smaller principal  amount) will be reduced.  Repayment of the original bond
principal upon maturity (as adjusted for inflation) is guaranteed in the case of
U.S.  Treasury  inflation-indexed  bonds,  even  during a period  of  deflation.
However,  the  current  market  value of the bonds is not  guaranteed,  and will
fluctuate. The Series may also invest in other inflation related bonds which may
or may not provide a similar  guarantee.  If a  guarantee  of  principal  is not
provided,  the  adjusted  principal  value of the bond repaid at maturity may be
less than the original principal.

         The value of inflation-indexed  bonds is expected to change in response
to changes in real interest  rates.  Real interest rates in turn are tied to the
relationship   between  nominal  interest  rates  and  the  rate  of  inflation.
Therefore,  if  inflation  were to rise at a faster rate than  nominal  interest
rates,  real interest  rates might  decline,  leading to an increase in value of
inflation-indexed  bonds. In contrast,  if nominal interest rates increased at a
faster  rate than  inflation,  real  interest  rates  might  rise,  leading to a
decrease in value of inflation-indexed bonds.

         The periodic  adjustment of U.S.  inflation-index  bonds is tied to the
Consumer Price-Index for Urban Consumers (CPI-U), which is calculated monthly by
the U.S.  Bureau of Labor  Statistics.  The CPI-U is a measurement of changes in
the cost of living, made up of components such as housing, food,  transportation
and energy. Inflation-indexed bonds issued by a foreign government are generally
adjusted to reflect a comparable inflation index, calculated by that government.
There can be no  assurance  that the CPI-U or any foreign  inflation  index will
accurately  measure  the real  rate of  inflation  in the  prices  of goods  and
services.  Moreover,  there can be no assurance  that the rate of inflation in a
foreign  country  will be  correlated  to the rate of  inflation  in the  United
States.

         Any increase in the principal amount of an inflation-indexed  bond will
be considered  taxable  ordinary  income,  even though  investors do not receive
their principal until maturity.

Investment Companies.  A Series may invest in investment companies to the extent
permitted  under the 1940 Act. As a shareholder  in an investment  company,  the
Series  would bear its pro rata  share of that  investment  company's  expenses,
which could result in  duplication  of certain fees,  including  management  and
administrative fees.

         A Series may invest cash balances into investment  companies managed by
a common investment adviser or its affiliates. A Series' investments in any such
fund will not be  subject  to any  additional  fees,  including  management  and
administrative fees.

Mortgage-Backed  Securities. A Series may invest in mortgage-backed  securities.
Mortgage-backed  securities are securities representing an interest in a pool of
mortgages.  The  mortgages  may be of a variety of types,  including  adjustable
rate,  conventional  30-year,   fixed-rate,   graduated  payment,  and  15-year.
Principal and interest payments made on the mortgages in the underlying mortgage
pool of a  mortgage-backed  security held by a Series are passed  through to the
Series.  This is in contrast to  traditional  bonds where  principal is normally
paid  back at  maturity  in a lump sum.  Unscheduled  prepayments  of  principal
shorten the securities'  weighted average life and may lower their total return.
(When a mortgage in the  underlying  mortgage  pool is prepaid,  an  unscheduled
principal prepayment is passed through to the Series. This principal is returned
to the Series at par.  As a result,  if a mortgage  security  were  trading at a
discount,  its total return would be  increased  by  prepayments).  The value of
these  securities also may change because of changes in the market's  perception
of the  creditworthiness  of the issuer.  In addition,  the mortgage  securities
market  in  general  may  be  adversely  affected  by  changes  in  governmental
regulation or tax policies.

Mortgage  Dollar Rolls. A Series may enter into mortgage dollar rolls in which a
Series sells  mortgage-backed  securities  for delivery in the current month and
simultaneously  contracts to repurchase substantially similar (same type, coupon
and maturity)  securities on a specified future date.  During the roll period, a
Series foregoes principal and interest paid on the mortgage-backed securities. A
Series is compensated by the interest earned on the cash proceeds of the initial
sale and from  negotiated  fees paid by brokers  offered as an inducement to the
Series to "roll  over" its  purchase  commitments.  A Series may only enter into
covered  rolls.  A "covered  roll" is a specific  type of dollar  roll for which
there is an  offsetting  cash  position  which  matures on or before the forward
settlement date of the dollar roll transaction. At the time a Series enters into
a mortgage  "dollar roll",  it will establish an account with its custodian bank
in which it will  maintain  cash,  U.S.  Government  securities  or other liquid
assets  equal in value to its  obligations  in  respect  of  dollar  rolls,  and
accordingly,  such  dollar  rolls will not be  considered  borrowings.  Mortgage
dollar rolls involve the risk that the market value of the securities the Series
is obligated to repurchase  under the agreement may decline below the repurchase
price.  In the event the buyer of securities  under a mortgage dollar roll files
for bankruptcy or becomes  insolvent,  the Series' use of proceeds of the dollar
roll may be  restricted  pending  a  determination  by the other  party,  or its
trustee or receiver, whether to enforce the Series' obligation to repurchase the
securities.

Participations and Assignments.  A Series may invest in fixed- and floating-rate
loans (Loans) arranged through private negotiations between a corporate borrower
or a foreign sovereign entity and one or more financial institutions  (Lenders).
A  Series  may  invest  in such  Loans in the  form of  participations  in Loans
(Participations) and assignments of all or a portion of Loans from third parties
(Assignments).  Participations  typically  will  result  in a  Series  having  a
contractual  relationship only with the Lender, not with the borrower.  A Series
will have the right to receive  payments of principal,  interest and any fees to
which it is entitled  only from the Lender  selling the  Participation  and only
upon receipt by the Lender of the payments from the borrower. In connection with
purchasing  Participations,  a Series  generally  will have no right to  enforce
compliance by the borrower with the terms of the loan agreement  relating to the
Loan,  nor any  rights of set-off  against  the  borrower,  and a Series may not
benefit  directly  from  any  collateral  supporting  the  Loan in  which it has
purchased the  Participation.  As a result, a Series will assume the credit risk
of both the  borrower and the Lender that is selling the  Participation.  In the
event of the insolvency of the Lender selling a  Participation,  a Series may be
treated as a general creditor of the Lender and may not benefit from any set-off
between the Lender and the borrower.  A Series will acquire  Participations only
if the Lender interpositioned between a Series and the borrower is determined by
the sub-adviser to be  creditworthy.  When a Series  purchases  Assignments from
Lenders,  a Series will acquire  direct rights against the borrower on the Loan,
except that under  certain  circumstances  such rights may be more  limited than
those held by the assigning Lender.

         A  Series   may  have   difficulty   disposing   of   Assignments   and
Participations.  Because the market for such instruments is not highly liquid, a
Series  anticipates that such instruments could be sold only to a limited number
of  institutional  investors.  The lack of a highly liquid  secondary market may
have an adverse impact on the value of such instruments and will have an adverse
impact  on  a  Series'   ability  to  dispose  of  particular   Assignments   or
Participations  in response to a specific  economic event, such as deterioration
in the  creditworthiness of the borrower.  A Series currently treats investments
in Participations  and Assignments as illiquid for purposes of its limitation on
investment in illiquid securities. However, the Trustees may in the future adopt
guidelines for  determining  whether  Assignments  and Loan  Participations  are
liquid or illiquid.

Passive Foreign  Investment  Companies.  A Series may purchase the securities of
passive foreign investment  companies.  A passive foreign investment company, in
general,  is a foreign corporation of which either at least 75% of its income is
passive or an average of at least 50% of its assets produce, or are held for the
production of, passive income. In addition to bearing their  proportionate share
of the Trust's expenses (management fees and operating  expenses),  shareholders
will also indirectly bear similar expenses of such investment companies.

Portfolio  Turnover.  To a limited  extent,  a Series may  engage in  short-term
transactions if such transactions further its investment objective. A Series may
sell one security and  simultaneously  purchase another of comparable quality or
simultaneously  purchase  and  sell  the  same  security  to take  advantage  of
short-term  differentials  in  bond  yields  or  otherwise  purchase  individual
securities in anticipation  of relatively  short-term  price gains.  The rate of
portfolio  turnover will not be a determining factor in the purchase and sale of
such  securities.   Increased   portfolio   turnover   necessarily   results  in
correspondingly  higher costs including brokerage  commissions,  dealer mark-ups
and other  transaction costs on the sale of securities and reinvestment in other
securities, and may result in the acceleration of taxable gains.

Real Estate  Investment  Trusts (REITs).  REITs are pooled  investment  vehicles
whose  assets  consist  primarily  of  interests  in real estate and real estate
loans.  The REITs in which a Series may invest include  equity REITs,  which own
real estate  properties  and realize income from rents and gain or loss from the
sale of real estate  interests,  and mortgage  REITs,  which make  construction,
development  and  long-term  mortgage  loans and realize  income  from  interest
payments on loans. The value of an equity REIT may be affected by changes in the
value of the underlying  property,  while a mortgage REIT may be affected by the
quality of the credit  extended.  The performance of both types of REITs depends
upon conditions in the real estate industry, management skills and the amount of
cash flow. The risks associated with REITs include defaults by borrowers,  heavy
cash flow dependency,  self-liquidation,  failure to qualify as a "pass-through"
entity under the Federal tax law,  failure to qualify as an exempt  entity under
the 1940 Act,  and the fact that REITs are not  diversified.  REITs  (especially
mortgage REITs) are subject to interest rate risk.

Repurchase Agreements and Reverse Repurchase Agreements.  A Series may invest in
repurchase or reverse repurchase agreements. A repurchase agreement involves the
purchase of a security by a Series and a simultaneous  agreement (generally by a
bank or dealer) to repurchase that security from the Series at a specified price
and date or upon demand.  This  technique  offers a method of earning  income on
idle cash. A repurchase agreement may be considered a loan collateralized by the
underlying security. The Series must take physical possession of the security or
receive  written  confirmation  of the purchase  and a custodial or  safekeeping
receipt from a third party or be recorded as the owner of the  security  through
the Federal Reserve Book Entry System.

         The Series may invest in open repurchase agreements which vary from the
typical  agreement  in the  following  respects:  (1) the  agreement  has no set
maturity,  but instead matures upon 24 hours' notice to the seller;  and (2) the
repurchase  price is not  determined  at the time the agreement is entered into,
but is  instead  based  on a  variable  interest  rate and the  duration  of the
agreement.  In addition,  a Series,  together with other  registered  investment
companies having management  agreements with a common investment  adviser or its
affiliates,  may transfer  uninvested cash balances into a single joint account,
the daily aggregate  balance of which will be invested in one or more repurchase
agreements.

         When a Series  invests in a reverse  repurchase  agreement,  it sells a
portfolio  security  to another  party,  such as a bank or a  broker-dealer,  in
return for cash, and agrees to buy the security back at a future date and price.
Reverse  repurchase  agreements may be used to provide cash to satisfy unusually
heavy redemption  requests or for other temporary or emergency  purposes without
the necessity of selling  portfolio  securities or to earn additional  income on
portfolio securities, such as Treasury bills and notes.

Short Sales. A Series may sell  securities  short. A short sale is the sale of a
security  the Series does not own. It is "against  the box" if at all times when
the short  position is open the Series owns an equal amount of the securities or
securities  convertible into, or exchangeable without further consideration for,
securities of the same issue as the securities  sold short. To the extent that a
Series  engages in short sales that are not "against the box," it must  maintain
asset coverage in the form of assets  determined to be liquid by the sub-adviser
in  accordance  with  procedures  established  by the  Board of  Trustees,  in a
segregated  account, or otherwise cover its position in a permissible manner. If
the value of the security goes up, the Series will have to buy it back at a loss
to make good on the borrowing.

Short-Term  Corporate  Debt  Securities.  A  Series  may  invest  in  short-term
corporate debt securities.  These are non-convertible  corporate debt securities
(e.g.,  bonds and debentures) which have one year or less remaining to maturity.
Corporate notes may have fixed, variable, or floating rates.

Standard  &  Poor's  Depository  Receipts  (SPDRs).  SPDRs  are  American  Stock
Exchange-traded  securities that represent  ownership in the SPDR Trust, a trust
which has been  established  to accumulate and hold a portfolio of common stocks
that is intended to track the price  performance  and dividend  yield of the S&P
500 Index.  The SPDR trust is sponsored by a  subsidiary  of the American  Stock
Exchange.  SPDRs may be used for several  reasons  including but not limited to:
facilitating  the  handling  of cash flows or trading,  or reducing  transaction
costs. The use of SPDRs would introduce additional risk to a Series as the price
movement of the instrument does not perfectly correlate with the price action of
the underlying index.

Stripped   Mortgage-Backed   Securities.   A  Series   may   purchase   stripped
mortgage-backed  securities,  which may be considered derivative mortgage-backed
securities,  which may be issued by  agencies or  instrumentalities  of the U.S.
Government or by private  entities.  Stripped  mortgage-backed  securities  have
greater  volatility  than other types of  mortgage-backed  securities.  Stripped
mortgage-backed  securities are structured with two or more classes that receive
different  proportions of the interest and principal  distributions on a pool of
mortgage  assets.  In the most extreme  case,  one class will receive all of the
interest (IOs, or interest-only securities),  while the other class will receive
all of the principal (POs, or principal-only securities).  The yield to maturity
of such mortgage-backed  securities that are purchased at a substantial discount
or premium are  extremely  sensitive to changes in interest  rates as well as to
the rate of principal payments (including prepayments) on the related underlying
mortgage assets.

         As interest  rates rise and fall, the value of IOs tends to move in the
same  direction  as  interest  rates.  The  value of the  other  mortgage-backed
securities  described herein, like other debt instruments,  will tend to move in
the opposite  direction  compared to interest rates.  Under the Internal Revenue
Code of 1986,  as amended  (Code),  POs may  generate  taxable  income  from the
current accrual of original issue discount, without a corresponding distribution
of cash to the Series.

         The cash flows and yields on IO and PO classes are extremely  sensitive
to the  rate  of  principal  payments  (including  prepayments)  on the  related
underlying  mortgage  assets.  For  example,  a rapid or slow rate of  principal
payments  may  have a  material  adverse  effect  on the  prices  of IOs or POs,
respectively.   If  the  underlying  mortgage  assets  experience  greater  than
anticipated  prepayments of principal,  an investor may fail to recoup fully its
initial investment in an IO class of a stripped  mortgage-backed  security, even
if the IO class is rated AAA or Aaa or is  derived  from a full faith and credit
obligation. Conversely, if the underlying mortgage assets experience slower than
anticipated  prepayments of principal,  the price on a PO class will be affected
more  severely  than  would  be  the  case  with a  traditional  mortgage-backed
security.

Supranational  Agency  Securities.  A Series may invest in securities  issued or
guaranteed  by  certain  supranational   entities,  such  as  the  International
Development Bank.

U.S. Government Securities.  U.S. Government securities are issued or guaranteed
as to principal and interest by U.S. Government  agencies or  instrumentalities.
These include  securities  issued by the Federal National  Mortgage  Association
(Fannie Mae),  Government  National Mortgage  Association  (Ginnie Mae), Federal
Home Loan Bank,  Federal  Land Banks,  Farmers  Home  Administration,  Banks for
Cooperatives,  Federal  Intermediate Credit Banks,  Federal Financing Bank, Farm
Credit  Banks,   the  Small   Business   Association,   Student  Loan  Marketing
Association,  and the Tennessee Valley Authority. Some of these securities, such
as those issued by Ginnie Mae, are supported by the full faith and credit of the
U.S.  Treasury;  others,  such as those of  Fannie  Mae,  are  supported  by the
discretionary  authority  of  the  U.S.  Government  to  purchase  the  agency's
obligations;  and still  others,  such as those of the  Student  Loan  Marketing
Association,  are  supported  only  by the  credit  of the  instrumentality.  No
assurance can be given that the U.S.  Government will provide  financial support
to U.S. Government agencies or  instrumentalities  in the future,  other than as
set forth above, since it is not obligated to do so by law.

U.S. Government  Obligations.  U.S. Government obligations include bills, notes,
bonds, and other debt securities issued by the U.S.  Treasury.  These are direct
obligations  of the U.S.  Government  and  differ  mainly in the length of their
maturities.

Variable  Rate  Securities.  Variable  rate  securities  provide  for a periodic
adjustment  in the  interest  rate  paid on the  obligations.  The terms of such
obligations  must provide that interest  rates are adjusted  periodically  based
upon  some  appropriate  interest  rate  adjustment  index  as  provided  in the
respective  obligations.  The adjustment intervals may be regular and range from
daily up to annually,  or may be event  based,  such as on a change in the prime
rate.

Warrants.  A Series may invest in warrants.  Warrants have no voting rights, pay
no dividends  and have no rights with  respect to the assets of the  corporation
issuing them.  Warrants basically are options to purchase equity securities at a
specific  price  valid  for a  specific  period of time.  They do not  represent
ownership of the  securities,  but only the right to buy them.  Warrants  differ
from call  options in that  warrants  are  issued by the issuer of the  security
which may be purchased on their exercise, whereas call options may be written or
issued by anyone. The prices of warrants do not necessarily move parallel to the
prices of the underlying securities.

When-Issued  Securities and Forward Commitment Contracts.  A Series may purchase
securities on a when-issued  or delayed  delivery basis  (When-Issueds)  and may
purchase securities on a forward commitment basis (Forwards).  Any or all of the
Series'  investments in debt securities may be in the form of  When-Issueds  and
Forwards.  The price of such securities,  which may be expressed in yield terms,
is fixed at the time the  commitment  to  purchase  is made,  but  delivery  and
payment take place at a later date. Normally,  the settlement date occurs within
90 days of the purchase for  When-Issueds,  but may be substantially  longer for
Forwards.  During the period between purchase and settlement, no payment is made
by the Series to the issuer and no interest accrues to the Series.  The purchase
of these  securities  will result in a loss if their value declines prior to the
settlement date. This could occur, for example, if interest rates increase prior
to  settlement.  The longer the period  between  purchase  and  settlement,  the
greater the risks. At the time the Series makes the commitment to purchase these
securities, it will record the transaction and reflect the value of the security
in determining its net asset value.  The Series will maintain cash and/or liquid
assets with its custodian bank at least equal in value to  commitments  for them
during the time between the purchase and the settlement.  Therefore,  the longer
this period,  the longer the period during which alternative  investment options
are not  available  to the  Series  (to the  extent of the  securities  used for
cover).  Such  securities  either  will mature or, if  necessary,  be sold on or
before the settlement date.

Zero Coupon and Pay-in-Kind Bonds.  Unless otherwise stated herein, a Series may
invest up to 10% of its assets in zero coupon bonds or strips. Zero coupon bonds
do not make regular interest payments;  rather, they are sold at a discount from
face value.  Principal and accreted discount  (representing interest accrued but
not paid) are paid at maturity.  Strips are debt securities that are stripped of
their interest after the securities are issued,  but otherwise are comparable to
zero coupon  bonds.  The market value of strips and zero coupon bonds  generally
fluctuates  in response to changes in  interest  rates to a greater  degree than
interest-paying  securities  of comparable  term and quality.  A Series may also
purchase  pay-in-kind  bonds.  Pay-in-kind  bonds pay all or a portion  of their
interest in the form of debt or equity securities.

         Zero coupon and  pay-in-kind  bonds tend to be subject to greater price
fluctuations  in  response  to  changes  in  interest  rates  than are  ordinary
interest-paying  debt  securities  with  similar  maturities.  The value of zero
coupon  securities  appreciates more during periods of declining  interest rates
and  depreciates  more during  periods of rising  interest  rates than  ordinary
interest-paying debt securities with similar maturities.  Zero coupon securities
and  pay-in-kind  bonds  may  be  issued  by a wide  variety  of  corporate  and
governmental issuers.

         Current  federal  income tax law  requires  the holder of a zero coupon
security,  certain  pay-in-kind bonds and certain other securities acquired at a
discount (such as Brady Bonds) to accrue income with respect to these securities
prior to the  receipt of cash  payments.  Accordingly,  to avoid  liability  for
federal income and excise taxes,  a Series may be required to distribute  income
accrued  with respect to these  securities  and may have to dispose of portfolio
securities  under  disadvantageous  circumstances  in order to generate  cash to
satisfy these distribution requirements.

                         ADDITIONAL RISK CONSIDERATIONS

Emerging Markets.  The considerations noted below under "Foreign Securities" may
be intensified in the case of investment in developing countries. Investments in
securities of issuers in emerging markets countries may involve a high degree of
risk and many may be considered speculative.  These investments carry all of the
risks of  investing in  securities  of foreign  issuers to a heightened  degree.
These heightened risks include: (i) greater risks of expropriation, confiscatory
taxation,  nationalization,  and less social,  political and economic stability;
(ii)  limitations  on daily  price  changes  and the small  current  size of the
markets for  securities  of emerging  markets  issuers and the  currently low or
nonexistent  volume of  trading,  resulting  in lack of  liquidity  and in price
volatility;  (iii)  certain  national  policies  which  may  restrict  a Series'
investment  opportunities including limitations on aggregate holdings by foreign
investors  and  restrictions  on  investing  in  issuers  or  industries  deemed
sensitive  to relevant  national  interests;  and (iv) the absence of  developed
legal structures  governing private or foreign  investment and private property.
In addition,  emerging  market  economies may be based on only a few industries,
may be highly vulnerable to changes in local or global trade conditions, and may
suffer from extreme and volatile debt burdens or inflation rates.

Foreign  Securities.  Investments  in  foreign  securities,  including  those of
foreign  governments,  involve  risks that are  different in some  respects from
investments in securities of U.S.  issuers,  such as the risk of fluctuations in
the value of the currencies in which they are denominated,  a heightened risk of
adverse  political  and  economic  developments  and,  with  respect  to certain
countries,  the possibility of  expropriation,  nationalization  or confiscatory
taxation or  limitations  on the  removal of funds or other  assets of a Series.
Securities  of some  foreign  issuers  in many  cases are less  liquid  and more
volatile than securities of comparable domestic issuers.  There also may be less
publicly available  information about foreign issuers than domestic issuers, and
foreign issuers  generally are not subject to the uniform  accounting,  auditing
and financial  reporting  standards,  practices and  requirements  applicable to
domestic  issuers.  Certain  markets may require  payment for securities  before
delivery.  A Series may have limited  legal  recourse  against the issuer in the
event of a default on a debt  instrument.  Delays may be encountered in settling
securities transactions in certain foreign markets and a Series will incur costs
in converting  foreign  currencies into U.S.  dollars.  Bank custody charges are
generally  higher for foreign  securities.  The Series which invest primarily in
foreign  securities  are  particularly   susceptible  to  such  risks.  American
Depositary  Receipts do not involve the same direct currency and liquidity risks
as foreign securities.

         The share price of a Series  that  invests in foreign  securities  will
reflect the  movements of both the prices of the  portfolio  securities  and the
currencies  in  which  such  securities  are  denominated.   A  Series'  foreign
investments  may  cause  changes  in a  Series'  share  price  that  have  a low
correlation  with  movement  in the U.S.  markets.  Because  most of the foreign
securities in which a Series invests will be denominated in foreign  currencies,
or  otherwise  will have  values  that  depend  on the  performance  of  foreign
currencies relative to the U.S. dollar, the relative strength of the U.S. dollar
may be an  important  factor in the  performance  of a Series,  depending on the
extent of the Series' foreign investments.

         A Series may employ certain strategies in order to manage exchange rate
risks.  For  example,  a  Series  may  hedge  some  or all  of  its  investments
denominated in or exposed to a foreign  currency  against a decline in the value
of that  currency.  A Series  may enter  into  contracts  to sell  that  foreign
currency  for  U.S.  dollars  (not  exceeding  the  value  of a  Series'  assets
denominated  in or exposed to that currency) or by  participating  in options or
futures contracts with respect to such currency (position hedge). A Series could
also hedge that  position  by selling a second  currency,  which is  expected to
perform   similarly  to  the  currency  in  which   portfolio   investments  are
denominated,  for U.S.  dollars  (proxy  hedge).  A Series may also enter into a
forward contract to sell the currency in which the security is denominated for a
second  currency that is expected to perform better  relative to the U.S. dollar
if the sub-adviser  believes there is a reasonable degree of correlation between
movements in the two currencies  (cross  hedge).  A Series may also enter into a
forward  contract  to  sell  a  currency  in  which  portfolio   securities  are
denominated  in exchange  for a second  currency in order to manage its currency
exposure  to  selected  countries.   In  addition,  when  a  Series  anticipates
purchasing  securities  denominated in or exposed to a particular currency,  the
Series may enter into a forward  contract to  purchase or sell such  currency in
exchange for the dollar or another currency (anticipatory hedge).

         These strategies  minimize the effect of currency  appreciation as well
as depreciation, but do not protect against a decline in the underlying value of
the hedged  security.  In addition,  such strategies may reduce or eliminate the
opportunity to profit from  increases in the value of the original  currency and
may adversely impact a Series'  performance if the  sub-adviser's  projection of
future exchange rates is inaccurate.

Futures, Options and Other Derivative Instruments.  The use of futures, options,
forward  contracts,  and  swaps  (derivative  instruments)  exposes  a Series to
additional  investment  risks and transaction  costs. If a sub-adviser  seeks to
protect a Series against potential adverse movements in the securities,  foreign
currency or interest rate markets using these  instruments,  and such markets do
not move in a direction  adverse to the Series,  that Series  could be left in a
less  favorable  position  than if such  strategies  had not  been  used.  Risks
inherent in the use of futures,  options,  forward  contracts and swaps include:
(i) the risk that interest rates,  securities  prices and currency  markets will
not move in the directions  anticipated;  (ii) imperfect correlation between the
price of derivative  instruments  and movements in the prices of the securities,
interest rates or currencies being hedged;  (iii) the fact that skills needed to
use these  strategies  are  different  from  those  needed  to select  portfolio
securities;  (iv) the  possible  absence  of a liquid  secondary  market for any
particular  instrument  at any time;  and (v) the possible need to defer closing
out certain hedged positions to avoid adverse tax consequences.

High-Yield/High-Risk  Bonds. Lower-rated bonds involve a higher degree of credit
risk,  which is the risk that the issuer  will not make  interest  or  principal
payments  when due. In the event of an  unanticipated  default,  a Series  would
experience  a  reduction  in its  income,  a decline in the market  value of the
securities  so affected  and a decline in the value of its shares.  More careful
analysis of the  financial  condition of issuers of  lower-rated  securities  is
therefore necessary. During an economic downturn or substantial period of rising
interest rates,  highly leveraged issuers may experience  financial stress which
could adversely  affect their ability to service  principal and interest payment
obligations,   to  meet  projected  business  goals  and  to  obtain  additional
financing.

         The  market  prices  of  lower-rated   securities  are  generally  less
sensitive  to interest  rate changes  than higher  rated  investments,  but more
sensitive to adverse economic or political changes,  or individual  developments
specific to the issuer.  Periods of economic or political uncertainty and change
can be expected to result in volatility of prices of these securities. Since the
last major economic recession,  there has been a substantial increase in the use
of high-yield debt securities to fund highly  leveraged  corporate  acquisitions
and restructurings, so past experience with high-yield securities in a prolonged
economic downturn may not provide an accurate  indication of future  performance
during such periods.  Lower-rated  securities  also may have less liquid markets
than higher-rated securities,  and their liquidity as well as their value may be
more severely affected by adverse economic conditions.  Many high-yield bonds do
not  trade  frequently.  When they do trade,  their  price may be  substantially
higher or lower  than had been  expected.  A lack of  liquidity  also means that
judgment may play a bigger role in valuing the securities. Adverse publicity and
investor  perceptions  as well as new or  proposed  laws may also have a greater
negative impact on the market for lower rated bonds.

         A Series may also  invest in unrated  debt  securities  of foreign  and
domestic  issuers.  Unrated debt,  while not  necessarily  of lower quality than
rated  securities,  may not have as broad a market.  Sovereign  debt of  foreign
governments  is generally  rated by country,  because  these ratings do not take
into account  individual  factors  relevant to each issue and may not be updated
regularly.  Because of the size and perceived  demand of the issue,  among other
factors,  certain  municipalities may not incur the costs of obtaining a rating.
The sub-adviser  will analyze the credit-  worthiness of the issuer,  as well as
any  financial  institution  or other  party  responsible  for  payments  on the
security,  in determining  whether to purchase  unrated  municipal  bonds.  (See
Appendix A for a description of bond rating categories).

High-Yield  Foreign  Sovereign Debt Securities.  Investing in fixed and floating
rate  high-yield  foreign  sovereign  debt  securities  will  expose  the Series
investing  in  such  securities  to  the  direct  or  indirect  consequences  of
political,   social  or  economic  changes  in  the  countries  that  issue  the
securities. (See "Foreign Securities.") The ability and willingness of sovereign
obligors  in  developing  and  emerging  market  countries  or the  governmental
authorities  that control  repayment of their external debt to pay principal and
interest  on such debt when due may depend on  general  economic  and  political
conditions  within  the  relevant  country.  Countries  such as those in which a
Series may invest have historically experienced, and may continue to experience,
high rates of inflation,  high interest rates,  exchange rate trade difficulties
and  extreme  poverty  and  unemployment.  Many  of  these  countries  are  also
characterized by political uncertainty or instability.  Additional factors which
may influence the ability or  willingness  to service debt include,  but are not
limited to, a country's  cash flow  situation,  the  availability  of sufficient
foreign  exchange on the date a payment is due,  the  relative  size of its debt
service burden to the economy as a whole,  and its  government's  policy towards
the  International  Monetary  Fund,  the  World  Bank  and  other  international
agencies.

Hybrid  Instruments.  The risks of  investing  in hybrid  instruments  reflect a
combination  of the risks of  investing  in  securities,  options,  futures  and
currencies, including volatility and lack of liquidity. Reference is made to the
discussion of futures, options, and forward contracts herein for a discussion of
these  risks.  Further,  the prices of the  hybrid  instrument  and the  related
commodity  or currency  may not move in the same  direction or at the same time.
Hybrid instruments may bear interest or pay preferred  dividends at below market
(or even relatively nominal) rates.  Alternatively,  hybrid instruments may bear
interest at above market rates but bear an increased risk of principal  loss. In
addition,  because the purchase and sale of hybrid  instruments could take place
in an  over-the-counter  or in a private  transaction between the Series and the
seller of the hybrid instrument,  the  creditworthiness  of the counter-party to
the transaction  would be a risk factor which the Series would have to consider.
Hybrid  instruments  also may not be  subject  to  regulation  of the  Commodity
Futures Trading  Commission,  which generally regulates the trading of commodity
futures by U.S. persons, the Securities and Exchange Commission, which regulates
the  offer  and  sale  of  securities  by  and to  U.S.  persons,  or any  other
governmental regulatory authority.

Securities  Lending.  Lending  securities  enables a Series  to earn  additional
income, but could result in a loss or delay in recovering these securities.  The
borrower of a Series' portfolio  securities must maintain acceptable  collateral
with that Series' custodian in an amount, marked to market daily, at least equal
to the  market  value  of the  securities  loaned,  plus  accrued  interest  and
dividends.  Acceptable collateral is limited to cash, U.S. government securities
and  irrevocable  letters of credit that meet certain  guidelines.  A Series may
reinvest any cash  collateral in money market  investments  or other  short-term
liquid investments. A Series will retain authority to terminate any of its loans
at any time. A Series may pay reasonable  fees in connection with a loan and may
pay the borrower or placing broker a negotiated  portion of the interest  earned
on the  reinvestment  of cash held as collateral.  A Series will receive amounts
equivalent to any dividends,  interest or other  distributions on the securities
loaned. A Series will regain record  ownership of loaned  securities to exercise
beneficial rights,  such as voting and subscription  rights, when regaining such
rights is considered to be in the Series' interest.

                INVESTMENT RESTRICTIONS APPLICABLE TO ALL SERIES

Fundamental Policies. Each Series is subject to certain fundamental policies and
restrictions that may not be changed without shareholder  approval.  Shareholder
approval  means  approval by the lesser of (i) more than 50% of the  outstanding
voting  securities of the Trust (or a particular Series if a matter affects just
that Series),  or (ii) 67% or more of the voting securities present at a meeting
if the  holders of more than 50% of the  outstanding  voting  securities  of the
Trust (or the  affected  Series) are  present or  represented  by proxy.  Unless
otherwise indicated, all restrictions apply at the time of investment.

         (1) Each Series,  except the JNL/Janus  Capital Growth Series,  JNL/S&P
Conservative  Growth  Series  I,  JNL/S&P  Moderate  Growth  Series  I,  JNL/S&P
Aggressive  Growth  Series I, JNL/S&P Very  Aggressive  Growth Series I, JNL/S&P
Equity  Growth  Series I, JNL/S&P  Equity  Aggressive  Growth  Series I, JNL/S&P
Conservative  Growth  Series II,  JNL/S&P  Moderate  Growth  Series II,  JNL/S&P
Aggressive  Growth Series II, JNL/S&P Very Aggressive  Growth Series II, JNL/S&P
Equity Growth Series II,  JNL/S&P  Equity  Aggressive  Growth Series II, JNL/S&P
Conservative Growth Series,  JNL/S&P Moderate Growth Series,  JNL/S&P Aggressive
Growth  Series,  Lazard/JNL  Small Cap Value Series and Lazard/JNL Mid Cap Value
Series, shall be a "diversified company," as such term is defined under the 1940
Act.

         (2) No Series may invest more than 25% of the value of their respective
assets in any  particular  industry  (other  than U.S.  Government  securities),
except the PPM America/JNL Money Market Series. The telecommunications  industry
is comprised of several services which are considered separate industries by the
sub-advisers.   Services  can  include  cellular,  long  distance,   paging  and
messaging,  satellite or data and internet. As the  telecommunications  industry
continues to expand, there will be more service industries created.

         (3) No Series may invest  directly in real estate or  interests in real
estate;  however,  the  Series  may own  debt or  equity  securities  issued  by
companies engaged in those businesses.

         (4) No Series may  purchase  or sell  physical  commodities  other than
foreign  currencies  unless acquired as a result of ownership of securities (but
this limitation shall not prevent the Series from purchasing or selling options,
futures,  swaps and forward  contracts or from  investing in securities or other
instruments backed by physical commodities).

         (5) No Series  may lend any  security  or make any other  loan if, as a
result,  more than 33 1/3% of the Series'  total  assets  would be lent to other
parties (but this  limitation  does not apply to purchases of commercial  paper,
debt securities or repurchase agreements).

         (6) No Series may act as an underwriter of securities issued by others,
except to the extent that a Series may be deemed an  underwriter  in  connection
with the disposition of portfolio securities of such Series.

         (7) No Series may invest  more than 15% of a Series' net assets (10% in
the case of the PPM  America/JNL  Money Market Series and the  JNL/Alger  Growth
Series) in illiquid  securities.  This  limitation  does not apply to securities
eligible  for  resale  pursuant  to Rule 144A of the  Securities  Act of 1933 or
Commercial  Paper  issued  in  reliance  upon the  exemption  from  registration
contained in Section 4(2) of that Act,  which have been  determined to be liquid
in accordance with guidelines established by the Board of Trustees.

         (8) The Series will not issue  senior  securities  except that they may
borrow  money  for  temporary  or  emergency  purposes  (not for  leveraging  or
investment)  in an amount  not  exceeding  25% of the value of their  respective
total  assets  (including  the amount  borrowed)  less  liabilities  (other than
borrowings).  If borrowings exceed 25% of the value of a Series' total assets by
reason of a decline in net assets,  the Series will reduce its borrowings within
three business days to the extent  necessary to comply with the 25%  limitation.
This policy shall not prohibit reverse repurchase agreements, deposits of assets
to margin  or  guarantee  positions  in  futures,  options,  swaps  and  forward
contracts, or the segregation of assets in connection with such contracts.

Operating Policies. The Trustees have adopted additional investment restrictions
for the Series.  These restrictions are operating policies of the Series and may
be  changed  by  the  Trustees  without  shareholder  approval.  The  additional

*Trustees who are interested persons as defined in the Investment Company Act of
1940.


         As of January 20, 2000,  the  officers and trustees of the Trust,  as a
group,  owned less than 1% of the then  outstanding  shares of the Trust. To the
extent required by applicable law, Jackson National Life Insurance  Company will
solicit  voting  instructions  from  owners of  variable  insurance  or variable
annuity  contracts.  All  shares of each  Series  of the Trust  will be voted by
Jackson National Life Insurance  Company in accordance with voting  instructions
received from such variable  contract  owners.  Jackson  National Life Insurance
Company  will vote all of the shares  which it is  entitled  to vote in the same
proportion as the voting  instructions given by variable contract owners, on the
issues  presented,  including  shares which are attributable to Jackson National
Life Insurance Company's interest in the Trust.

         The trustees who are  "interested  persons" and officers as  designated
above receive no  compensation  from the Trust.  Disinterested  Trustees will be
paid $5,000 for each meeting of the Board of Trustees that they attend. The fees
to the  disinterested  Trustees are divided  among the funds in the Fund Complex
based on their relative size.

For the year ended December 31, 1999, the  disinterested  Trustees  received the
following fees from the Trust for service as Trustee:

                                   PERFORMANCE

         A  Series'  historical  performance  may be  shown in the form of total
return and yield.  These performance  measures are described below.  Performance
advertised  for a Series may or may not reflect  the effect of any charges  that
are imposed under a variable annuity  contract  (Contract) that is funded by the
Trust. Such charges, described in the prospectus for the Contract, will have the
effect of reducing a Series' performance.

         Standardized  average  annual total return and  non-standardized  total
return  measure both the net investment  income  generated by, and the effect of
any realized and  unrealized  appreciation  or  depreciation  of, the underlying
investments  of a Series.  Yield is a measure of the net  investment  income per
share earned over a specific one month or 30-day  period  (seven-day  period for
the PPM  America/JNL  Money Market Series)  expressed as a percentage of the net
asset value.

         A  Series'  standardized  average  annual  total  return  quotation  is
computed in accordance  with a  standardized  method  prescribed by rules of the
Securities  and Exchange  Commission  (SEC).  Standardized  average annual total
return shows the percentage rate of return of a hypothetical  initial investment
of $1,000 for the most recent one-, five- and ten-year periods,  or for a period
covering the time the Series has been in existence if the Series has not been in
existence  for one of the  prescribed  periods.  Because  average  annual  total
returns  tend to smooth  out  variations  in the  Series'  returns,  you  should
recognize  that  they  are not the  same as  actual  year-by-year  results.  The
standardized  average annual total return for a Series for a specific  period is
found by first taking a hypothetical $1,000 investment  (initial  investment) in
the  Series'  shares on the first day of the  period,  adjusting  to deduct  the
applicable  charges,  if  any,  and  computing  the  redeemable  value  of  that
investment at the end of the period. The redeemable value is then divided by the
initial  investment,  and this quotient is taken to the Nth root (N representing
the number of years in the period) and 1 is subtracted from the result, which is
then  expressed as a  percentage.  The  calculation  assumes that all income and
capital  gains  dividends  paid by the Series have been  reinvested at net asset
value on the reinvestment dates during the period.

         The  standardized  average  annual total return for each Series for the
periods indicated was as follows:

Index Series,  the JNL  International  Index Series,  the JNL Russell 2000 Index
Series,  the JNL S&P 500 Index Series,  and the JNL S&P MidCap Index Series were
not in operation in 1999.  Prior to May 1, 1997,  the PPM  America/JNL  Balanced
Series  was  the  JNL/Phoenix   Investment   Counsel  Balanced  Series  and  was
sub-advised by Phoenix Investment Counsel Inc., the JNL/Putnam Growth Series was
the JNL/Phoenix  Investment Counsel Growth Series and was sub-advised by Phoenix

         A Series'  performance  may be  affected  by risks  specific to certain
types  of  investments,  such as  foreign  securities,  derivative  investments,
non-investment  grade  debt  securities,  initial  public  offerings  (IPOs)  or
companies  with  relatively  small  market   capitalizations.   IPOs  and  other
investment  techniques may have magnified  performance impact on a Series with a
small asset base. A Series may not experience similar  performance as its assets
grow.

         The standardized average annual total return quotations will be current
to the  last  day of the  calendar  quarter  preceding  the  date  on  which  an
advertisement  is submitted for  publication.  The  standardized  average annual
total return will be based on rolling calendar  quarters and will cover at least
periods of one, five and ten years, or a period covering the time the Series has
been in  existence,  if it has not been in existence  for one of the  prescribed
periods.

         Non-standardized total return may also be advertised.  Non-standardized
total return may be for periods other than those required to be presented or may
otherwise differ from standardized average annual total return. Non-standardized
total return for a specific  period is  calculated by first taking an investment
(initial  investment)  in the Series'  shares on the first day of the period and
computing the end value of that  investment at the end of the period.  The total
return percentage is then determined by subtracting the initial  investment from
the ending  value and  dividing  the  remainder  by the initial  investment  and
expressing the result as a percentage.  The calculation  assumes that all income
and capital gains dividends paid by the Series have been reinvested at net asset
value on the reinvestment dates during the period. Non-standardized total return
may also be shown as the increased dollar value of the  hypothetical  investment
over the period.

         Quotations   of   standardized   average   annual   total   return  and
non-standardized  total  return  are based  upon  historical  earnings  and will
fluctuate. Any quotation of performance,  therefore,  should not be considered a
guarantee of future  performance.  Factors affecting the performance of a Series
include general market conditions, operating expenses and investment management.

         The yield for a Series  other  than the PPM  America/JNL  Money  Market
Series is computed in accordance  with a standardized  method  prescribed by the
rules of the SEC. The yield is calculated by assuming that the income  generated
by the investment during that 30-day period is generated each 30-day period over
a 12-month  period and is shown as a percentage  of the  investment.  Under this
method, yield is computed by dividing the net investment income per share earned
during the specified one month or 30-day period by the offering  price per share
on the last day of the period, according to the following formula:

                                     a-b   6
                  YIELD   =       2[(---+1)  -1]
                                     cd


Where:
         a = dividends and interest earned during the period.
         b = expenses accrued for the period (net of reimbursements).
         c = the average daily number of shares outstanding during the
             period that were entitled to receive dividends.
         d = the  offering  price (net asset value) per share on the last day of
             the period.


         The yield for the 30-day  period ended  December 31, 1999,  for each of
the referenced Series was as follows:

          PPM America/JNL Balanced Series                             3.83%
          PPM America/JNL High-Yield Bond Series                     10.21%
          Salomon Brothers/JNL Balanced Series                        2.96%
          Salomon Brothers/JNL Global Bond Series                     8.12%
          Salomon Brothers/JNL High-Yield Bond Series                 9.71%
          Salomon Brothers/JNL U.S. Government & Quality Bond Series  6.22%

         In  computing  the   foregoing   yield,   the  Series  follow   certain
standardized  accounting  practices  specified by SEC rules. These practices are
not necessarily  consistent with those that the Series use to prepare annual and
interim financial  statements in accordance with generally  accepted  accounting
principles.

         The PPM  America/JNL  Money Market  Series'  yield is also  computed in
accordance  with a  standardized  method  prescribed  by rules of the SEC.  This
Series' yield is a measure of the net dividend and interest income earned over a
specific seven-day period expressed as a percentage of the offering price of the
Series. The yield is an annualized  figure,  which means that it is assumed that
the Series  generates the same level of net income over a 52-week period.  Under
this method,  the current yield quotation is based on a seven-day  period and is
computed as follows.  The first  calculation is net investment income per share;
which is accrued  interest  on  portfolio  securities,  plus or minus  amortized
discount or premium,  less accrued expenses.  This number is then divided by the
price per share  (expected to remain  constant at $1.00) at the beginning of the
period (base period  return).  The result is then divided by 7 and multiplied by
365 and the resulting  yield figure is carried to the nearest  one-hundredth  of
one percent.  Realized  capital gains or losses and unrealized  appreciation  or
depreciation  of  investments  are  not  included  in the  calculation.  The PPM
America/JNL  Money Market Series' yield for the seven-day  period ended December
31, 1999, was 5.37%.

         The PPM America/JNL  Money Market Series' effective yield is determined
by taking the base period return  (computed as described  above) and calculating
the effect of assumed compounding. The formula for the effective yield is: (base
period return + 1)365/7 - 1. The PPM America/JNL  Money Market Series' effective
yield for the seven-day period ended December 31, 1999, was 5.52%.

         A Series' performance  quotations are based upon historical results and
are not necessarily representative of future performance. The Series' shares are
sold at net asset value. Returns and net asset value will fluctuate, except that
the PPM  America/JNL  Money  Market  Series  seeks to maintain a $1.00 net asset
value per share.  Factors affecting a Series' performance include general market
conditions, operating expenses and investment management. Shares of a Series are
redeemable  at the then current net asset value,  which may be more or less than
original cost.

         The  performance  of the Series may be compared to the  performance  of
other mutual funds or mutual fund indices with similar  objectives  and policies
as  reported  by Lipper  Analytical  Services,  Inc.  (Lipper),  CDA  Investment
Technologies,  Inc.  (CDA) or  Donoghue's  Money  Fund  Report.  Lipper  and CDA
performance  calculations  are based upon  changes  in net asset  value with all
dividends  reinvested  and do not  include  the effect of any sales  charges.  A
Series'  performance may also be compared to that of the Consumer Price Index or
various  unmanaged  stock and bond  indices  including,  but not  limited to the
Consumer  Price Index,  the  Standard & Poor's 500 Index,  the Standard & Poor's
MidCap 400 Index,  the Morgan Stanley  Capital  International  All Country World
Free (ex-U.S.) Index, the Morgan Stanley Capital  International World Index, the
Lehman Brothers Aggregate Bond Index, the Lehman Brothers  High-Yield Index, the
Merrill  Lynch  Treasury  Bill Index (3 month),  the Salomon  Smith Barney Broad
Investment  Grade Bond Index,  the Salomon Smith Barney High Yield Market Index,
the Salomon Brothers  Treasury Index, the Russell 2000 Index, the Russell Midcap
Index, the Morgan Stanley Europe and Australasia, Far East Equity Index, the S&P
Micropal  Asset  Allocation  USA Income Funds Sector Index,  or the S&P Micropal
Asset  Allocation USA Balanced Funds Sector Index,.  No adjustments are made for
taxes payable on  dividends.  Lipper and CDA are widely  recognized  independent
mutual fund reporting services.  Lipper and CDA indices are weighted performance
averages of other mutual funds with similar investment objectives.

         From  time  to  time,  a  Series  also  may  quote   information   from
publications including,  but not limited to, the following:  Morningstar,  Inc.,
The Wall Street Journal, Money Magazine,  Forbes,  Barron's, The New York Times,
USA Today, Institutional Investor and Registered Representative. Also, investors
may want to compare the historical returns of various  investments,  performance
indices of those investments or economic  indicators,  including but not limited
to stocks, bonds,  certificates of deposit and other bank products, money market
funds and U.S. Treasury  obligations.  Certain of these alternative  investments
may offer fixed rates of return and  guaranteed  principal,  and may be insured.
Economic indicators may include,  without limitation,  indicators of market rate
trends  and cost of funds,  such as Federal  Home Loan Bank Board 11th  District
Cost of Funds Index (COFI).

         The net asset values and returns of the Series will  fluctuate.  Shares
of a Series are  redeemable  by an investor at the then current net asset value,
which may be more or less than original cost.

         A Series may periodically advertise tax-deferred compounding charts and
other hypothetical illustrations.

*   When average net assets exceed this amount,  the sub-advisory fee asterisked
    is applicable to all amounts in this Series.

         The  sub-advisory  fees payable by JNFS to a sub-adviser may be reduced
as agreed to by the  parties  from time to time.  With  respect  to the  Salomon
Brothers/JNL  Global Bond Series and in connection with the advisory  consulting
agreement  between Salomon Brothers and SBAM Limited,  Salomon Brothers will pay
SBAM Limited,  as full compensation for all services provided under the advisory
consulting  agreement,  a portion of its investment  management  fee. The amount
payable to SBAM Limited will be equal to the fee payable under Salomon Brothers'
sub-advisory  agreement  multiplied  by the  portion of the assets of the Series
that SBAM Limited has been  delegated to manage  divided by the current value of
the net assets of the Series.

         Subject  to the  supervision  of JNFS  and  the  Trustees  pursuant  to
investment  sub-advisory  agreements  entered  into between JNFS and each of the
sub-advisers,  respectively,  the  sub-advisers  invest and reinvest the Series'
assets  consistent  with  the  Series'  respective   investment  objectives  and
policies.  The investment  sub-advisory  agreement  continues in effect for each
Series  from  year  to  year  after  its  initial  two-year  term so long as its
continuation is approved at least annually by a majority of the Trustees who are
not parties to such agreement or interested  persons of any such party except in
their capacity as Trustees of the Series and by the shareholders of the affected
Series or the Board of Trustees.  It may be  terminated at any time upon 60 days
notice by either  party,  or by a majority vote of the  outstanding  shares of a
Series  with  respect to that  Series,  and will  terminate  automatically  upon
assignment  or upon  the  termination  of the  investment  management  agreement
between  JNFS and the  Series.  Additional  Series may be subject to a different
agreement.  The  sub-advisers are responsible for compliance with or have agreed
to use their best efforts to manage the Series to comply with the  provisions of
Section  817(h)  of  the  Code,  applicable  to  each  Series  (relating  to the
diversification  requirements  applicable to investments in underlying  variable
annuity contracts).

The Distributor. Jackson National Life Distributors, Inc. (the "Distributors" or
"JNLD"),  401  Wilshire  Boulevard,   Santa  Monica,  California  90401  is  the
distributor.  JNLD  is a  wholly  owned  subsidiary  of  Jackson  National  Life
Insurance  Company,  which is in turn  wholly  owned by  Prudential  plc, a life
insurance company in the United Kingdom. The Distribution Agreement was approved
by the Board of Trustees on August 10, 2000.

Brokerage Enhancement Plan. The Board of Trustees of the Trust, including all of
the Trustees  who are not  "interested  persons"  (as defined in the  Investment
Company  Act of 1940) of the Trust,  the  Investment  Adviser,  the  Distributor
(referred to as the  "Independent  Trustees")  and the  shareholders  of certain
Series have voted  pursuant to the provisions of Rule 12b-1 under the Investment
Company Act of 1940 to adopt a Brokerage  Enhancement  Plan (the "Plan") for the
purpose of utilizing the Trust's brokerage  commissions to the extent available,
to promote the sale and  distribution of the Trust's shares (through the sale of
variable insurance products funded by the Trust).

Under the Plan, the Distributor,  on behalf of the Trust is authorized to direct
the Investment  Adviser or a sub-adviser  to effect  brokerage  transactions  in
portfolio  securities  through  certain  broker-dealers,   consistent  with  the
obligation to achieve best price and execution. These broker-dealers have agreed
either (1) to pay a portion of their  commission  from the sale and  purchase of
securities to the Series,  which will then be passed to the Distributor or other
introducing brokers ("Brokerage Payments") that provide distribution activities,
or (2) to provide  brokerage  credits,  benefits or other  services  ("Brokerage
Credits") to be used for distribution activities in addition to the execution of
the trade. The Distributor will use a part of the Brokerage Payments and Credits
to defray its legal and administrative  costs associated with  implementation of
the Plan.  These  expenses  are  expected to be  minimal.  Th  remainder  of the
Brokerage   Payments  or  Brokerage  Credits  generated  will  be  used  by  the
Distributor to finance activities  principally intended to result in the sale of
the Trust's shares. These activities will include, but are not limited to:

         o        holding  or  participating  in  seminars  and  sales  meetings
                  promoting the sale of the Trust's shares
         o        paying marketing fees requested by broker-dealers who sell the
                  variable insurance products
         o        training sales personnel
         o        creating and mailing advertising and sales literature
         o        financing any other activity that is intended to result in the
                  sale of Trust's shares.

The  Distributor  is obligated to use all amounts  generated  under the Plan for
distribution  expenses,  except  for a small  amount  to be used to  defray  the
incidental  costs  associated  with  implementation  of the  Plan.  The Plan may
indirectly  benefit the Distributor in that amounts  expended under the Plan may
help defray, n whole or in part,  distribution  expenses that otherwise might be
borne by the Distributor or an affiliate.

The Plan provides (1) that it will be subject to annual approval by the Trustees
and the Independent Trustees; (2) that the Distributor must provide the Trustees
with a quarterly  written report of payments made under the Plan and the purpose
of the payments and (3) that the Plan may be  terminated at any time by the vote
of a  majority  of the  Independent  Trustees.  The Plan may not be  amended  to
increase materially the amount to be spent for distribution  without shareholder
approval,  and all material  Plan  amendments  must be approved by a vote of the
Independent  Trustees.  In  addition,   the  selection  and  nomination  of  the
Independent Tustees must be committed to the Independent Trustees.


Series Transactions and Brokerage.  Pursuant to the Sub-advisory Agreements, the
sub-advisers are responsible for placing all orders for the purchase and sale of
portfolio  securities  of the Trust.  The  sub-advisers  have no formula for the
distribution of the Trust's brokerage  business,  their intention being to place
orders for the purchase  and sale of  securities  with the primary  objective of
obtaining  the  most  favorable  overall  results  for the  Trust.  The  cost of
securities  transactions for each portfolio will consist  primarily of brokerage
commissions or dealer or underwriter spreads. Bonds and money market instruments
are generally traded on a net basis and do not normally involve either brokerage
commissions or transfer taxes.

         Occasionally, securities may be purchased directly from the issuer. For
securities  traded primarily in the  over-the-counter  market,  the sub-advisers
will,  where  possible,  deal  directly  with  dealers  who make a market in the
securities  unless better prices and  execution  are available  elsewhere.  Such
dealers usually act as principals for their own account.

         In selecting  brokers and dealers through whom to effect  transactions,
the  sub-advisers  will give  consideration  to a number of  factors,  including
price,  dealer  spread or  commission,  if any, the  reliability,  integrity and
financial condition of the broker-dealer, size of the transaction and difficulty
of execution.  Consideration of these factors by a sub-adviser,  either in terms
of a particular  transaction or the sub-adviser's overall  responsibilities with
respect to the Trust and any other accounts  managed by the  sub-adviser,  could
result in the Trust paying a commission  or spread on a  transaction  that is in
excess of the amount of commission or spread  another  broker-dealer  might have
charged for executing the same  transaction.  In selecting  brokers and dealers,
the  sub-advisers  will also give  consideration to the value and quality of any
research, statistical, quotation or valuation services provided by the broker or
dealer.  In placing a purchase or sale  order,  a  sub-adviser  may use a broker
whose  commission in effecting the transaction is higher than that of some other
broker if the sub-adviser determines in good faith that the amount of the higher
commission  is reasonable in relation to the value of the brokerage and research
services  provided  by such  broker,  viewed in terms of either  the  particular
transaction or the sub-adviser's  overall  responsibilities  with respect to the
Trust and any other accounts managed by the Sub-adviser.  Brokerage and research
services  provided by brokers and dealers  include  advice,  either  directly or
through  publications  or  writings,   as  to  the  value  of  securities,   the
advisability of purchasing or selling securities, the availability of securities
or  purchasers  or sellers of  securities,  and analyses and reports  concerning
issuers,  industries,  securities,  economic  factors  and trends and  portfolio
strategy.  Consistent  with the foregoing  considerations  and the Rules of Fair
Practice  of the NASD,  a  sub-adviser  may  consider  the sale of shares of the
Series  or  variable  insurance  products  that  use the  Series  as  investment
vehicles, or may consider or follow recommendations of JNFS that take such sales
into  account,  as factors  in the  selection  of  brokers  to effect  portfolio
transactions  for a  Series,  subject  to the  requirements  of best  net  price
available  and most  favorable  execution.  In this  regard,  JNFS may  direct a
sub-adviser  to try to  effect  a  portion  of a  Series'  transactions  through
broker-dealers  that give  prominence to variable  insurance  products using the
Series as  investment  vehicles,  to the extent  consistent  with best net price
available and most favorable execution.

         To the  extent  research  services  are  used  by the  sub-advisers  in
rendering investment advice to the Trust, such services would tend to reduce the
sub-advisers'  expenses.  However, the sub-advisers do not believe that an exact
dollar value can be assigned to these services.  Research  services  received by
the sub-advisers  from brokers or dealers  executing  transactions for the Trust
will be  available  also for the  benefit  of other  portfolios  managed  by the
sub-advisers.

         The  Trustees  periodically  review the  Adviser's  performance  of its
responsibilities  in connection with the placement of portfolio  transactions on
behalf of the Series and review  commissions paid by the Series over a period of
time to  determine  if they are  reasonable  in  relation  to the benefit to the
Series.

         Any portfolio  transaction for a Series may be executed through brokers
that  are  affiliated  with the  Trust,  JNFS  and/or  sub-adviser,  if,  in the
sub-adviser's  judgment,  the use of such affiliated brokers is likely to result
in  price  and  execution  at  least as  favorable  as those of other  qualified
brokers, and if, in the transaction,  the affiliated broker charges the Series a
commission  rate  consistent  with  those  charged by the  affiliated  broker to
comparable unaffiliated customers in similar transactions. All transactions with
affiliated brokers will comply with Rule 17e-1 under the 1940 Act.

         There may be occasions  when portfolio  transactions  for the Trust are
executed  as part of  concurrent  authorizations  to  purchase  or sell the same
security for trusts or other accounts served by affiliated  companies of JNFS or
the sub-advisers.  Although such concurrent authorizations  potentially could be
either advantageous or disadvantageous to the Trust, they are effected only when
JNFS and the sub-advisers believe that to do so is in the interest of the Trust.
When such concurrent authorizations occur the executions will be allocated in an
equitable manner.

         During the periods indicated,  the Series paid the following amounts in
brokerage commissions:

Code of Ethics.  To mitigate  the  possibility  that a Series will be  adversely
affected by personal trading of employees,  the Trust, JNFS and the sub-advisers
have  adopted  Codes of Ethics  under  Rule 17j-1 of the 1940 Act.  These  Codes
contain  policies  restricting  securities  trading in personal  accounts of the
portfolio  managers and others who normally come into  possession of information
on portfolio  transactions.  These Codes comply, in all material respects,  with
the  recommendations of the Investment  Company Institute.  Employees subject to
the Code of Ethics may invest in securities for their own  investment  accounts,
including securities that may be purchased or held by the Trust.

                  PURCHASES, REDEMPTIONS AND PRICING OF SHARES

         An  insurance  company  may  purchase  shares  of the  Series  at their
respective net asset values,  using premiums  received with respect to Contracts
issued by the company's separate accounts. These separate accounts are funded by
shares of the Trust.

         All investments in the Trust are credited to the shareholder's  account
in the form of full and fractional  shares of the designated  Series (rounded to
the nearest 1/1000 of a share). The Trust does not issue share certificates.

         As stated in the  Prospectus,  the net asset  value  (NAV) of a Series'
shares is determined  once each day on which the New York Stock Exchange  (NYSE)
is open  (Business  Day) at the  close of the  regular  trading  session  of the
Exchange (normally 4:00 p.m., Eastern Time, Monday through Friday). The NAV of a
Series'  shares is not  determined  on the days the NYSE is  closed,  which days
generally are New Year's Day, Martin Luther King Jr. holiday,  President's  Day,
Good  Friday,  Memorial  Day,  Independence  Day,  Labor Day,  Thanksgiving  and
Christmas.

         The per share NAV of a Series is determined by dividing the total value
of the securities  and other assets,  less  liabilities,  by the total number of
shares  outstanding.  In  determining  NAV,  securities  listed on the  national
securities exchanges,  the Nasdaq National Market and foreign markets are valued
at the  closing  prices on such  markets,  or if such price is  lacking  for the
trading period immediately preceding the time of determination,  such securities
are  valued  at their  current  bid  price.  Securities  that are  traded on the
over-the-counter  market  are  valued  at  their  closing  bid  prices.  Foreign
securities and currencies are converted to U.S.  dollars using exchange rates in
effect at the time of  valuation.  A Series may  determine  the market  value of
individual  securities  held by it,  by  using  prices  provided  by one or more
professional  pricing  services  which may provide market prices to other funds,
or, as needed, by obtaining market  quotations from independent  broker-dealers.
Short-term  securities  maturing within 60 days are valued on the amortized cost
basis.

         Trading in securities on European and Far Eastern securities  exchanges
and  over-the-counter  markets is  normally  completed  well before the close of
business on each Business Day. In addition,  European and Far Eastern securities
trading generally or in a particular  country or countries may not take place on
all  Business  Days.  Furthermore,  trading  takes place in Japanese  markets on
certain  Saturdays and in various foreign markets on days which are not Business
Days and on which a Series' NAV is not calculated.  A Series  calculates NAV per
share, and therefore  effects sales,  redemptions and repurchases of its shares,
as of the  close of the NYSE  once on each day on which  the NYSE is open.  Such
calculation does not take place  contemporaneously with the determination of the
prices  of the  majority  of the  foreign  portfolio  securities  used  in  such
calculation.

         For the PPM America/JNL  Money Market Series,  securities are valued at
amortized cost,  which  approximates  market value, in accordance with Rule 2a-7
under the 1940 Act. The net income of the PPM America/JNL Money Market Series is
determined once each day, on which the NYSE is open, at the close of the regular
trading  session of the NYSE (normally 4:00 p.m.,  Eastern time,  Monday through
Friday).  All the net income of the  Series,  so  determined,  is  declared as a
dividend to  shareholders  of record at the time of such  determination.  Shares
purchased  become  entitled to dividends  declared as of the first day following
the date of  investment.  Dividends  are  distributed  in the form of additional
shares of the Series on the last  business  day of each month at the rate of one
share (and  fraction  thereof) of the Series for each one dollar  (and  fraction
thereof) of dividend income.

         For this purpose,  the net income of the PPM  America/JNL  Money Market
Series (from the time of the immediately preceding  determination thereof) shall
consist  of: (a) all  interest  income  accrued on the  portfolio  assets of the
Series,  (b) less all actual  and  accrued  expenses,  and (c) plus or minus net
realized  gains and losses on the assets of the Series  determined in accordance
with generally accepted accounting principles. Interest income includes discount
earned  (including  both original  issue and market  discount) on discount paper
accrued ratably to the date of maturity. Securities are valued at amortized cost
which  approximates  market,  which the Trustees  have  determined in good faith
constitutes fair value for the purposes of complying with the 1940 Act.

         Because the net income of the PPM  America/JNL  Money Market  Series is
declared  as a dividend  each time the net income is  determined,  the net asset
value per share (i.e.,  the value of the net assets of the Series divided by the
number of shares outstanding)  remains at one dollar per share immediately after
each such determination and dividend declaration. Any increase in the value of a
shareholder's  investment  in  the  Series,  representing  the  reinvestment  of
dividend  income,  is  reflected  by an  increase in the number of shares of the
Series in its  account.  Pursuant to its  objective of  maintaining  a fixed one
dollar share price,  the Series will not  purchase  securities  with a remaining
maturity  of more  than 397 days and will  maintain  a  dollar-weighted  average
portfolio maturity of 90 days or less.

         The Trust may suspend the right of redemption for any Series only under
the  following  unusual  circumstances:  (a) when the NYSE is closed (other than
weekends and holidays) or trading is restricted;  (b) when an emergency  exists,
making  disposal of  portfolio  securities  or the  valuation  of net assets not
reasonably  practicable;  or (c)  during  any  period  when the  Securities  and
Exchange  Commission  has by order  permitted a suspension of redemption for the
protection of shareholders.


                             ADDITIONAL INFORMATION

Description of Shares. The Declaration of Trust permits the Trustees to issue an
unlimited  number of full and fractional  shares of beneficial  interest of each
Series and to divide or combine  such shares into a greater or lesser  number of
shares without thereby changing the  proportionate  beneficial  interests in the
Trust. Each share of a Series represents an equal proportionate interest in that
Series with each other share.  The Trust  reserves the right to create and issue
any number of Series of shares.  In that case,  the shares of each Series  would
participate  equally in the earnings,  dividends,  and assets of the  particular
Series.  Upon  liquidation of a Series,  shareholders  are entitled to share pro
rata  in  the  net  assets  of  such  Series   available  for   distribution  to
shareholders.

Voting Rights. Shareholders are entitled to one vote for each share held. Except
for matters affecting a particular Series, as described below, all shares of the
Trust have equal voting  rights and may be voted in the election of Trustees and
on  other  matters  submitted  to the  vote of the  shareholders.  Shareholders'
meetings  ordinarily  will  not be held  unless  required  by the 1940  Act.  As
permitted by Massachusetts law, there normally will be no shareholders' meetings
for the purpose of electing  Trustees unless and until such time as fewer than a
majority of the Trustees  holding office have been elected by  shareholders.  At
that time, the Trustees then in office will call a shareholders' meeting for the
election of Trustees.  The Trustees must call a meeting of shareholders  for the
purpose of voting upon the removal of any Trustee when requested to do so by the
record holders of 10% of the  outstanding  shares of the Trust. A Trustee may be
removed  after  the  holders  of  record  of not  less  than  two-thirds  of the
outstanding  shares  have  declared  that  the  Trustee  be  removed  either  by
declaration  in writing  or by votes  cast in person or by proxy.  Except as set
forth  above,  the  Trustees  shall  continue  to hold  office  and may  appoint
successor  Trustees,  provided that  immediately  after the  appointment  of any
successor Trustee,  at least two-thirds of the Trustees have been elected by the
shareholders.  Shares do not have cumulative voting rights.  Thus,  holders of a
majority of the shares  voting for the  election  of Trustees  can elect all the
Trustees.

         In matters  affecting only a particular  Series,  the matter shall have
been effectively  acted upon by a majority vote of that Series even though:  (1)
the matter has not been approved by a majority vote of any other Series;  or (2)
the matter has not been approved by a majority vote of the Trust.

         Shareholders  of a  Massachusetts  business  trust may,  under  certain
circumstances,  be held personally liable as partners for the obligations of the
Trust.  The risk of a shareholder  incurring  any  financial  loss on account of
shareholder  liability  is limited to  circumstances  in which the Trust  itself
would be unable to meet its  obligations.  The  Declaration of Trust contains an
express disclaimer of shareholder liability for acts or obligations of the Trust
and  provides  that notice of the  disclaimer  must be given in each  agreement,
obligation or instrument entered into or executed by the Trust or Trustees.  The
Declaration  of Trust  provides  for  indemnification  of any  shareholder  held
personally  liable for the  obligations  of the Trust and also  provides for the
Trust to reimburse the shareholder  for all legal and other expenses  reasonably
incurred in connection with any such claim or liability.

         No  amendment  may be made to the  Declaration  of  Trust  without  the
affirmative  vote of a majority  of the  outstanding  shares of the  Trust.  The
Trustees  may,  however,  amend the  Declaration  of Trust  without  the vote or
consent of shareholders to:

         o        designate Series of the Trust; or

         o        change the name of the Trust; or

         o        supply  any  omission,   cure,   correct,  or  supplement  any
                  ambiguous, defective, or inconsistent provision to conform the
                  Declaration of Trust to the requirements of applicable federal
                  or state regulations if they deem it necessary.

If  not  terminated  by  the  vote  or  written  consent  of a  majority  of its
outstanding  shares,  the  Trust  will  continue  indefinitely.  Shares  have no
pre-emptive or conversion rights. Shares are fully paid and non-assessable.

Shareholder  Inquiries.  All inquiries regarding the Trust should be directed to
the Trust at the telephone number or address shown on the back cover page of the
Prospectus.

                                   TAX STATUS

         The Trust's policy is to meet the  requirements  of Subchapter M of the
Internal Revenue Code. Each Series intends to distribute  taxable net investment
income and capital  gains to  shareholders  in amounts  that will avoid  federal
income or excise  tax.  In  addition,  each  Series  intends to comply  with the
diversification  requirements of Code Section 817(h) related to the tax-deferred
status of annuity  and life  insurance  contracts  issued by  insurance  company
separate accounts.  If any Series failed to qualify for treatment as a regulated
investment  company for any  taxable  year,  (1) it would be taxed at  corporate
rates on the full amount of its taxable  income for that year without being able
to deduct the distributions it makes to its  shareholders,  (2) the shareholders
would treat all those distributions, including distributions of net capital gain
(the excess of net long-term capital gain over net short-term  capital loss), as
dividends (that is, ordinary  income) to the extent of the Series'  earnings and
profits,  and (3) most  importantly,  each insurance  company  separate  account
invested  therein  would fail to satisfy  the  diversification  requirements  of
Section 817(h), with the result that the variable annuity contracts supported by
that account  would no longer be eligible  for tax  deferral.  In addition,  the
Series could be required to recognize  unrealized  gains, pay substantial  taxes
and  interest  and  make  substantial   distributions  before  requalifying  for
regulated investment company treatment.

         All income dividends and capital gain distributions,  if any, on Series
shares are reinvested  automatically  in additional  shares of the Series at the
NAV  determined  on the first  Business Day  following  the record date,  unless
otherwise requested by a shareholder.

         Each  Series is treated as a separate  corporation  for  purpose of the
Code and,  therefore,  the assets,  income, and distributions of each Series are
considered  separately  for  purposes of  determining  whether or not the Series
qualifies as a regulated investment company.

                      APPENDIX A -- RATINGS OF INVESTMENTS

Moody's Investors Service, Inc.

Commercial  Paper Ratings.  The ratings  Prime-1 and Prime-2 are the two highest
commercial paper ratings assigned by Moody's Investors Service,  Inc. (Moody's).
Among the factors  considered by it in assigning ratings are the following:  (1)
evaluation  of the  management  of the issuer;  (2) economic  evaluation  of the
issuer's industry or industries and an appraisal of speculative-type risks which
may be inherent in certain  areas;  (3)  evaluation of the issuer's  products in
relation to competition and  customer-acceptance;  (4) liquidity; (5) amount and
quality of long-term debt; (6) trend of earnings over a period of ten years; (7)
financial  strength of a parent company and the  relationships  which exist with
the issuer;  and (8)  recognition by the management of obligations  which may be
present or may arise as a result of public interest  questions and  preparations
to meet such  obligations.  Relative  strength or weakness of the above  factors
determines whether the issuer's commercial paper is rated Prime-1 or 2.

Bond Ratings.
    AAA.  Bonds which are rated Aaa are judged to be of the best  quality.  They
carry the smallest  degree of investment  risk and are generally  referred to as
"gilt-edge."  Interest  payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change,  such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

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

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

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

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

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

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

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

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


Standard & Poor's Ratings Services

Issue Credit Ratings  Definitions.  A Standard & Poor's issue credit rating is a
current opinion of the creditworthiness of an obligor with respect to a specific
financial obligation,  a specific class of financial obligations,  or a specific
financial program (including ratings on medium-term note programs and commercial
paper programs). It takes into consideration the creditworthiness of guarantors,
insurers,  or other forms of credit enhancement on the obligation and takes into
account the currency in which the  obligation is  denominated.  The issue credit
rating  is  not  a  recommendation  to  purchase,  sell,  or  hold  a  financial
obligation,  inasmuch as it does not comment as to market  price or  suitability
for a particular investor.

Issue credit ratings are based on current information  furnished by the obligors
or  obtained  by Standard & Poor's  from other  sources it  considers  reliable.
Standard & Poor's does not perform an audit in connection with any credit rating
and may, on occasion,  rely on unaudited financial  information.  Credit ratings
may  be  changed,  suspended,  or  withdrawn  as a  result  of  changes  in,  or
unavailability of, such information, or based on other circumstances.

Issue credit ratings can be either long-term or short-term.  Short-term  ratings
are  generally  assigned  to  those  obligations  considered  short-term  in the
relevant  market.  In the U.S.,  for  example,  that means  obligations  with an
original  maturity  of no more  than  365  days -  including  commercial  paper.
Short-term ratings are also used to indicate the  creditworthiness of an obligor
with  respect to put  features on  long-term  obligations.  The result is a dual
rating, in which the short-term rating addresses the put feature, in addition to
the usual long-term rating. Medium-term notes are assigned long-term ratings.

Long-Term  Issue  Credit  Ratings.  Issue credit  ratings are based,  in varying
degrees, on the following considerations:

        1.  Likelihood of  payment-capacity  and  willingness  of the obligor to
            meet its financial  commitment  on an obligation in accordance  with
            the terms of the obligation;
        2.  Nature of and provisions of the obligation;
        3.  Protection  afforded by, and relative position of, the obligation in
            the event of bankruptcy,  reorganization, or other arrangement under
            the laws of bankruptcy and other laws affecting creditors' rights.

The issue rating  definitions  are  expressed in terms of default risk. As such,
they  pertain  to  senior  obligations  of an  entity.  Junior  obligations  are
typically rated lower than senior obligations,  to reflect the lower priority in
bankruptcy,  as noted above.  (Such  differentiation  applies when an entity has
both senior and subordinated obligations,  secured and unsecured obligations, or
operating company and holding company obligations.) Accordingly,  in the case of
junior debt, the rating may not confirm exactly with the category definition.

    AAA. An obligation  rated AAA has the highest rating  assigned by Standard &
Poor's.  The  obligor's  capacity  to  meet  its  financial  commitment  on  the
obligation is extremely strong.

    AA. An obligation rated AA differs from the  highest-rated  obligations only
in small degree. The obligor's capacity to meet its financial  commitment on the
obligation is very strong.

    A. An obligation rated A is somewhat more susceptible to the adverse effects
of  changes  in  circumstances  and  economic  conditions  than  obligations  in
higher-rated  categories.  However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.

    BBB.  An  obligation  rated BBB  exhibits  adequate  protection  parameters.
However,  adverse economic conditions or changing  circumstances are more likely
to lead to a weakened  capacity of the obligor to meet its financial  commitment
on the obligation.

    Obligations  rated BB, B, CCC, CC, and C are regarded as having  significant
speculative characteristics.  BB indicates the least degree of speculation and C
the highest. While such obligations will likely have some quality and protective
characteristics,  these  may be  outweighed  by  large  uncertainties  or  major
exposures to adverse conditions.

    BB. An  obligation  rated BB is less  vulnerable  to  nonpayment  than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse  business,  financial,  or economic  conditions  which could lead to the
obligor's   inadequate  capacity  to  meet  its  financial   commitment  on  the
obligation.

    B. An obligation  rated B is more vulnerable to nonpayment than  obligations
rated BB, but the  obligor  currently  has the  capacity  to meet its  financial
commitment  on  the  obligation.   Adverse  business,   financial,  or  economic
conditions will likely impair the obligor's  capacity or willingness to meet its
financial commitment on the obligation.

    CCC. An obligation rated CCC is currently  vulnerable to nonpayment,  and is
dependent upon  favorable  business,  financial and economic  conditions for the
obligor to meet its  financial  commitment  on the  obligation.  In the event of
adverse business,  financial, or economic conditions,  the obligor is not likely
to have the capacity to meet its financial commitment on the obligation.

    CC.  An obligation rated CC is currently highly vulnerable to nonpayment.

    C. The C rating may be used to cover a situation where a bankruptcy petition
has been filed or similar action has been taken, but payments on this obligation
are being continued.

    D. An obligation  rated D is in payment  default.  The D rating  category is
used when  payments  on an  obligation  are not made on the date due even if the
applicable grace period has not expired,  unless Standard & Poor's believes that
such payments  will be made during such grace period.  The D rating also will be
used upon the filing of a bankruptcy  petition or the taking of a similar action
if payments on an obligation are jeopardized.

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

    r. This symbol is attached to the ratings of  instruments  with  significant
noncredit  risks.  It  highlights  risks to principal or  volatility of expected
returns  which  are  not  addressed  in the  credit  rating.  Examples  include:
obligations  linked  or  indexed  to  equities,   currencies,   or  commodities;
obligations   exposed  to  severe  prepayment   risk-such  as  interest-only  or
principal-only  mortgage  securities;   and  obligations  with  unusually  risky
interest terms, such as inverse floaters.

Short-Term Issue Credit Ratings.
    A-1. A short-term  obligation  rated A-1 is rated in the highest category by
Standard & Poor's.  The obligor's  capacity to meet its financial  commitment on
the  obligation  is  strong.  Within  this  category,  certain  obligations  are
designated  with a plus sign (+). This indicates that the obligor's  capacity to
meet its financial commitment on these obligations is extremely strong.

    A-2. A short-term  obligation  rated A-2 is somewhat more susceptible to the
adverse  effects  of changes  in  circumstances  and  economic  conditions  than
obligations in higher rating categories. However, the obligor's capacity to meet
its financial commitment on the obligation is satisfactory.

    A-3.  A  short-term   obligation  rated  A-3  exhibits  adequate  protection
parameters.  However,  adverse economic conditions or changing circumstances are
more likely to lead to a weakened  capacity of the obligor to meet its financial
commitment on the obligation.

    B. A  short-term  obligation  rated  B is  regarded  as  having  significant
speculative characteristics.  The obligor currently has the capacity to meet its
financial  commitment  on  the  obligation;  however,  it  faces  major  ongoing
uncertainties which could lead to the obligor's  inadequate capacity to meet its
financial commitment on the obligation.

    C. A short-term obligation rated C is currently vulnerable to nonpayment and
is dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation.

    D. A  short-term  obligation  rated D is in  payment  default.  The D rating
category  is used when  payments on an  obligation  are not made on the date due
even if the applicable  grace period has not expired,  unless  Standard & Poor's
believes that such payments will be made during such grace period.  The D rating
also will be used upon the filing of a  bankruptcy  petition  or the taking of a
similar action if payments on an obligation are jeopardized.

Local Currency and Foreign  Currency Risks.  Country risk  considerations  are a
standard part of Standard & Poor's  analysis for credit ratings on any issuer or
issue.  Currency of  repayment  is a key factor in this  analysis.  An obligor's
capacity to repay foreign currency obligations may be lower than its capacity to
repay  obligations in its local currency due to the sovereign  government's  own
relatively  lower  capacity  to  repay  external  versus  domestic  debt.  These
sovereign risk  considerations  are incorporated in the debt ratings assigned to
specific  issues.  Foreign currency issuer ratings are also  distinguished  from
local currency  issuer ratings to identify those instances where sovereign risks
make them different for the same issuer.

Item 25. Indemnification.

                  Article VIII of the Registrant's  Agreement and Declaration of
                  Trust   provides  that  each  of  its  Trustees  and  Officers
                  (including  persons who serve at the  Registrant's  request as
                  directors,  officers or trustees  of another  organization  in
                  which  the  Registrant  has  any  interest  as a  shareholder,
                  creditor or otherwise)  (each,  a "Covered  Person")  shall be
                  indemnified  by the  Registrant  against all  liabilities  and
                  expenses  that may be  incurred  by  reason of being or having
                  been such a Covered  Person,  except  that no  Covered  Person
                  shall be  indemnified  against any liability to the Registrant
                  or  its  shareholders  to  which  such  Covered  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 such Covered Person's office.

                  The foregoing indemnification  arrangements are subject to the
                  provisions of Section 17(h) of the  Investment  Company Act of
                  1940.

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

                  In addition  to the above  indemnification,  Jackson  National
                  Life Insurance Company extends its  indemnification of its own
                  officers,  directors  and  employees  to cover  such  persons'
                  activities   as   officers,   trustees  or  employees  of  the
                  Registrant,  and by separate  agreement  Jackson National Life
                  Insurance  Company  has agreed to  indemnify  trustees  of the
                  Registrant who are not interested persons of the Registrant or
                  its investment adviser.
