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  primarily  in  a
diversified portfolio of equity securities -- common stock, preferred stock, and
securities  convertible  into or  exchangeable  for  common  stock -- of  large,
U.S.-traded  companies.  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.

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 since these shares were first offered and
shows how  performance has varied from year to year. The table shows the Series'
average annual returns and compares them to the market indicators  listed.  Both
the chart and the table assume  reinvestment of dividends and distributions.  As
with all  mutual  funds,  the  Series'  past  performance  does not  necessarily
indicate how it will perform in the future.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The  JNL/Alger  Growth  Series  seeks to achieve  its  investment  objective  of
long-term  capital  appreciation by investing  primarily in equity securities 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.

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 75 Maiden  Lane,  New York,  New York
10038.  Alger  Management  is  generally  engaged in the  business of  rendering
investment   advisory   services  to  institutions  and,  to  a  lesser  extent,
individuals and has been so engaged since 1964.

David D. Alger,  President and Chief Investment Officer of Alger Management,  is
primarily  responsible for the day-to-day  management of the Series. He has been
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.
Ronald Tartaro also  participates  in the management of the Series.  Mr. Tartaro
has been employed by Alger  Management as a senior  research  analyst since 1990
and as a Senior Vice  President  since 1995.  Mr. Alger and Mr. Tartaro have had
responsibility  for the day-to-day  management of the Series since the inception
of the Series.

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,  which include securities  convertible into or exchangeable for
common stock. The Series invests in U.S. and foreign companies,  generally those
of large market capitalization. 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    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. 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. 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 table below shows the performance of the Series and of the market indicators
listed since the Series began operation. The performance of the Series will vary
from year to year. As with all mutual funds,  the Series' past  performance does
not necessarily indicate how it will perform in the future.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The  JNL/Alliance  Growth  Series seeks to achieve its  investment  objective of
long-term  growth  of  capital  by  investing  primarily  in  common  stocks  or
securities with common stock  characteristics that the sub-adviser believes have
the potential for capital  appreciation.  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 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.

The Sub-Adviser and Portfolio Management

The sub-adviser to the JNL/Alliance Growth Series is Alliance Capital Management
L.P.  (Alliance),  with  principal  offices at 1345 Avenue of the Americas,  New
York, New York 10105. Alliance is a major international investment manager whose
clients  primarily  are  major  corporate  employee  benefit  funds,  investment
companies, foundations, endowment funds and public employee retirement systems.

James G.  Reilly,  Senior Vice  President of Alliance,  is  responsible  for the
day-to-day  management of the Series.  Mr. Reilly joined  Alliance in 1984.  Mr.
Reilly has had responsibility for the day-to-day  management of the Series since
the inception of the Series.

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  primarily  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   invests  in
          securities which it believes have sufficient growth potential to offer
          above-average,  long-term capital appreciation.  These securities have
          expected earnings-per-share growth or return on equity that, in either
          case, is greater than the average of the S&P 500 when acquired for the
          Series.

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

          --   price-to-earnings ratio or price-to-book value ratio of less than
               or approximately equal to 75% of the S&P 500,

          --   yield that  approximates  at least half of the  average  yield to
               maturity  of the Lehman  Brothers  Long  Treasury  Bond Index (or
               similar index),

          --   per  share  going  concern  value  that,  in  the   sub-adviser's
               judgment, exceeds book value and market value, or

          --   long-term debt equal to or below tangible net worth.

     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.

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.

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

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

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
normally  reevaluates a security if it underperforms  the S&P 500 by 15% or more
during a three-month period. 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.

Under the value  equity  strategy,  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.

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.

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.

The Sub-Adviser and Portfolio Management

The  sub-adviser to the JNL/Eagle Core Equity Series is Eagle Asset  Management,
Inc. (Eagle), 880 Carillon Parkway, St. Petersburg, Florida 33716. Eagle and its
affiliates   provide  a  wide  range  of   financial   services  to  retail  and
institutional clients.

In its capacity as  sub-adviser,  Eagle  supervises  and manages the  investment
portfolio  of the Series.  Eagle  utilizes a team of senior  portfolio  managers
acting together to manage the assets of the Series.  The team meets regularly to
review portfolio  holdings and to discuss  purchase and sale activity.  The team
adjusts holdings in the portfolio as it deems  appropriate in the pursuit of the
Series' investment objective.

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  primarily  in  a
diversified  portfolio of equity  securities  of domestic  small  capitalization
companies.  A small  capitalization  company is one that, at the time the Series
buys its securities,  has a market  capitalization under $1 billion. 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.  Generally,  the Series invests in securities that the sub-adviser
believes are  undervalued  in relation to their  long-term  earning power or the
asset value of their issuers and have significant future growth potential.

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  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.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The JNL/Eagle  SmallCap Equity Series invests primarily in the equity securities
of small capitalization U.S. companies.  However, it may also invest in American
Depositary Receipts of U.S. traded foreign issuers, U.S. Government  securities,
repurchase agreements and other short-term money market instruments.

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  sub-adviser  to  the  JNL/Eagle  SmallCap  Equity  Series  is  Eagle  Asset
Management,  Inc. (Eagle), 880 Carillon Parkway, St. Petersburg,  Florida 33716.
Eagle and its  affiliates  provide a wide range of financial  services to retail

equity accounts. Prior to joining Eagle, Mr. Boksen was employed for 16 years by
Raymond  James &  Associates,  Inc.  in its  institutional  research  and  sales
department.  While  employed by Raymond  James &  Associates,  Inc.,  Mr. Boksen
served as co-head of  Research,  Chief  Investment  Officer and  Chairman of the
Raymond  James &  Associates,  Inc.  Focus List  Committee.  Mr.  Boksen has had
responsibility  for the day-to-day  management of the Series since the inception
of the Series.

JNL/J.P. MORGAN ENHANCED S&P 500 INDEX SERIES

Investment Objective

The investment objective of the JNL/J.P. Morgan Enhanced S&P 500 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.  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.

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.

Performance

The  performance  of the Series will vary from year to year.  As with all mutual
funds, the Series' past  performance  does not necessarily  indicate how it will
perform in the future.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

In managing the JNL/J.P.  Morgan Enhanced S&P 500 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-adviser's research
               and valuation rankings.

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.

The  sub-adviser  to the JNL/J.P.  Morgan  Enhanced S&P 500 Index Series is J.P.

inception of the Series.

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.  The Series  also  invests in the equity  securities  of  companies  in
developing  countries or  "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 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. 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. 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  market  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.

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

The table below shows the performance of the Series and of the market indicators

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The JNL/J.P. Morgan International & Emerging Markets Series seeks to achieve its
investment  objective  through  a  combination  of  country  allocation,   stock
selection and currency management.  The sub-adviser uses a disciplined portfolio
construction  process to seek to enhance  returns and reduce  volatility  in the
market  value of the  Series.  To  allocate  the  Series  within  developed  and
developing  markets,  the sub-adviser  uses fundamental  research,  quantitative
valuation  techniques and experienced judgment to identify those countries whose
equity prices appear most attractive relative to future earnings prospects.

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.

Using a variety  of  quantitative  valuation  techniques  and based on  in-house
research,  the  sub-adviser  ranks  issuers in each  country  within  industrial
sectors  according  to their  relative  value.  The  Series  generally  seeks to
diversify its investments across industrial sectors in each country.

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

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.

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 Series may invest in companies of any size, from
larger,  well-established  companies to smaller,  emerging growth companies. The
Series may invest to a lesser  degree in other  types of  securities,  including
preferred stock, warrants, convertible securities and debt 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    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. 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. 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.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

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  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 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.

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.  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.

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    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. 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. 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" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The JNL/Janus  Capital Growth Series seeks to achieve its objective by investing
primarily in common  stocks  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,  1998,  they  ranged  between
approximately  $142 million and $73 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  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.

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  primarily  in  a
diversified  portfolio  of common  stocks of foreign and domestic  issuers.  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.

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    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. 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. 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    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.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The  JNL/Janus  Global  Equities  Series  invests  primarily in common stocks of
foreign  and  domestic  companies  and,  to a  lesser  degree,  other  types  of
securities,  such as bonds and other debt securities.  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 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 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/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.

The average duration of the Series typically ranges between three and six years,
although the maturities of the securities it holds may vary. 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 and
other  indexed  instruments,  in  seeking  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. 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. 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
          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 are do not  correlate  with prices  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.

     are not annualized.
**   For the period from _______________, 1998 through December 31, 1998.

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

management of the Series since the inception of the Series.

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 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. 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. 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.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The  JNL/Putnam  Growth  Series  invests  primarily in the equity  securities of
domestic,  large  capitalization  companies.  However, 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.

C. Beth Cotner has responsibility  for the day-to-day  management of the Series.
Ms.  Cotner,  Senior Vice  President,  has been  employed as a Senior  Portfolio
Manager by Putnam since September 1995.  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 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. 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.

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. 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. 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.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

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.

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/Eagle  Core  Equity  Series,  JNL/Eagle  SmallCap  Equity  Series,
JNL/Janus Aggressive Growth Series,  JNL/Janus Capital Growth Series,  JNL/Janus
Global  Equities  Series,  JNL/Putnam  Growth  Series,  JNL/Putnam  Value Equity
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  International  Equity Investment
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 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. 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.  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  market
          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" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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.

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/Eagle  Core Equity  Series,  JNL/Eagle  SmallCap  Equity  Series,  JNL/Janus
Aggressive  Growth Series,  JNL/Janus  Capital Growth Series,  JNL/Janus  Global
Equities Series,  JNL/Putnam Growth Series,  JNL/Putnam Value Equity 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  International  Equity Investment
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.

          emerging  markets,   which  involves  greater  risk.  Emerging  market

          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" as such term is

          that more than 5%, but not more than 25%,  of its total  assets may be

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/Eagle  Core  Equity  Series,  JNL/Eagle  SmallCap  Equity  Series,
JNL/Janus Aggressive Growth Series,  JNL/Janus Capital Growth Series,  JNL/Janus
Global  Equities  Series,  JNL/Putnam  Growth  Series,  JNL/Putnam  Value Equity
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  International  Equity Investment
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. 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.  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" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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.

Performance

The table below shows the performance of the Series and of the market indicators
since the Series began  operation.  The performance of the Series will vary from
year to year. As with all mutual funds,  the Series' past  performance  does not
necessarily indicate how it will perform in the future.

capital growth.

Principal Investment Strategies

The Series seeks to achieve its objective by investing in a diversified group of

the JNL/S&P Very Aggressive  Growth Series I may invest are the JNL/Alger Growth

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  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. 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.  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" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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.

Principal Risks of Investing in the Series

An  investment  in the Series is not  guaranteed.  As with any mutual fund,  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

          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. 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.  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" as that term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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.

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/Eagle  Core  Equity  Series,  JNL/Eagle  SmallCap  Equity  Series,
JNL/Janus Aggressive Growth Series,  JNL/Janus Capital Growth Series,  JNL/Janus
Global  Equities  Series,  JNL/Putnam  Growth  Series,  JNL/Putnam  Value Equity
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  International  Equity Investment
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  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. 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.  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  market
          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" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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.

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/PIMCO Total
Return Bond Series,  JNL/Putnam  Growth Series,  JNL/Putnam Value Equity Series,
Goldman  Sachs/JNL  Growth & Income  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,  T. Rowe  Price/JNL  International  Equity
Investment 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. 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.  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  market
          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" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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.

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/PIMCO Total Return Bond Series,  JNL/Putnam Growth Series,  JNL/Putnam Value
Equity Series,  Goldman  Sachs/JNL  Growth & Income  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,  T.  Rowe  Price/JNL
International  Equity  Investment  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. 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.  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  market
          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" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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

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/PIMCO Total
Return Bond Series,  JNL/Putnam  Growth Series,  JNL/Putnam Value Equity Series,
Goldman  Sachs/JNL  Growth & Income  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,  T. Rowe  Price/JNL  International  Equity
Investment 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.

          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" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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.

JNL/S&P VERY AGGRESSIVE GROWTH SERIES II

Investment Objective

The  investment  objective of the JNL/S&P Very  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
JNL/S&P Very 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/PIMCO Total
Return Bond Series,  JNL/Putnam  Growth Series,  JNL/Putnam Value Equity Series,
Goldman  Sachs/JNL  Growth & Income  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,  T. Rowe  Price/JNL  International  Equity
Investment 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  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. 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.  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" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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.

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/PIMCO Total
Return Bond Series,  JNL/Putnam  Growth Series,  JNL/Putnam Value Equity Series,

Investment 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  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. 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.  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  market
          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" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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.

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/PIMCO
Total Return Bond Series,  JNL/Putnam  Growth  Series,  JNL/Putnam  Value Equity
Series,  Goldman  Sachs/JNL  Growth & Income  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,  T. Rowe Price/JNL  International
Equity Investment 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  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. 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.  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" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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.

Performance

The table below shows the performance of the Series and of the market indicators
listed since the Series began operation. The performance of the Series will vary

not necessarily indicate how it will perform in the future.

Additional  Information  About  the  Principal  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 or cash  equivalents.
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  Index  Series,  JNL/J.P.  Morgan
International & Emerging  Markets Series,  JNL/Janus  Aggressive  Growth Series,
JNL/Janus Global Equities Series, JNL/PIMCO Total Return Bond Series, JNL/Putnam
Growth Series, JNL/Putnam Value Equity Series, Goldman Sachs/JNL Growth & Income
Series,  Lazard/JNL Small Cap Value Series, Lazard/JNL Mid 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, T.
Rowe Price/JNL  International  Equity Investment  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

          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. 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.  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  market
          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" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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.

Performance

The  performance  of the Series will vary from year to year.  As with all mutual
funds, the Series' past  performance  does not necessarily  indicate how it will
perform in the future.

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  Index  Series,  JNL/J.P.  Morgan
International & Emerging  Markets Series,  JNL/Janus  Aggressive  Growth Series,
JNL/Janus Global Equities Series, JNL/PIMCO Total Return Bond Series, JNL/Putnam
Growth Series, JNL/Putnam Value Equity Series, Goldman Sachs/JNL Growth & Income
Series,  Lazard/JNL Small Cap Value Series, Lazard/JNL Mid 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, T.
Rowe Price/JNL  International  Equity Investment  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    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. 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.  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  market
          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" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be

          risk than  another  fund  holding a larger  number of  issuers,  since
          changes in the financial condition or market status of a single issuer

JNL/SSGA ENHANCED INTERMEDIATE BOND INDEX SERIES

Investment Objective

The investment  objective of the JNL/SSGA 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 Series invests in
a diversified portfolio of intermediate-maturity,  investment-grade fixed-income
securities, primarily U.S. Government, corporate and asset-backed securities.

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.

     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
          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 are do not  correlate  with prices  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.  As with all mutual
funds, the Series' past  performance  does not necessarily  indicate how it will
perform in the future.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The JNL/SSGA  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  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.

The sub-adviser to the JNL/SSGA Enhanced Intermediate Bond Index Series is State
Street Global  Advisors  (SSGA),  located at One  International  Place,  Boston,
Massachusetts   02110.  Since  1978,  SSGA  has  been  providing   comprehensive

Product Group, Anne B. Eisenberg, Principal of SSGA, Susan R. Bonfeld, Principal
of SSGA,  and James B. May,  Assistant  Vice  President of SSGA,  share  primary
responsibility  for the day-to-day  management of the Series. Ms. Blake has been
with SSGA since 1987.  Ms.  Eisenberg has been with SSGA since 1982. Ms. Bonfeld
has been with SSGA  since  1994;  prior to that,  she spent  seven  years in the

JNL/SSGA INTERNATIONAL INDEX SERIES

Investment Objective

The  investment  objective  of the  JNL/SSGA  International  Index  Series is to
closely match the performance of the Morgan Stanley Capital International Europe
and  Australasia,  Far East  Equity  Index (MSCI EAFE  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 EAFE Index.  The Series  typically
holds all  securities  contained  in the MSCI EAFE  Index.  To better  track the
performance of the Index and provide liquidity, the Series may hold EAFE 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. 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. 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  market  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.

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.  As with all mutual
funds, the Series' past  performance  does not necessarily  indicate how it will
perform in the future.

JNL/SSGA RUSSELL 2000 INDEX SERIES

Investment Objective

The investment objective of the JNL/SSGA 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.

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.  As with all mutual
funds, the Series' past  performance  does not necessarily  indicate how it will
perform in the future.

JNL/SSGA S&P 500 INDEX SERIES

Investment Objective

The  investment  objective  of the  JNL/SSGA  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

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

GOLDMAN SACHS/JNL GROWTH & INCOME SERIES

Investment Objective

The investment  objectives of the Goldman  Sachs/JNL  Growth & Income Series are
long-term growth of capital and growth of income.

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 that the sub-adviser  believes to have favorable prospects for capital
appreciation  and/or  dividend-paying  ability.  The Series  may also  invest in
fixed-income securities (typically of investment grade) that offer the potential
to further the Series' investment  objectives.  The Series may invest in foreign
securities,  including  securities of issuers in emerging markets and securities
quoted in foreign currencies.

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. 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. 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    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.

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

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The  Goldman  Sachs/JNL  Growth & Income  Series  invests  primarily  in  equity
securities of companies which the sub-adviser  believes are underpriced relative
to a combination  of such factors as the company's  long-term  earnings,  growth
rate, free cash flow and/or dividend paying ability.

The  sub-adviser  gives  consideration  to the  business  quality of the issuer.
Factors   affecting  the   sub-adviser's   view  of  that  quality  include  the
competitiveness  and degree of  regulation  in the  markets in which the company
operates,  the  existence  of a  management  team with a record of success,  the
position of the company in the  markets in which it  operates,  the level of the
company's  financial  leverage and the sustainable return on capital invested in
the  business.  The Series may also purchase  securities of companies  that have
experienced  difficulties  and that,  in the  opinion  of the  sub-adviser,  are
available at attractive prices.

The  sub-adviser  uses first-hand  fundamental  research in choosing the Series'
securities  and  applies  macro  analysis  of numerous  economic  and  valuation
variables to anticipate  changes in company earnings and the overall  investment
climate.  The  sub-adviser  draws on the  research  and market  expertise of its
affiliates  as well as  information  provided by other  securities  dealers.  In
general,  the  sub-adviser  sells equity  securities  held by the Series when it
believes  that the  market  price  fully  reflects  or exceeds  the  securities'
fundamental valuation or when it identifies other, more attractive investments.

The Series may invest up to 10% of its total assets in debt securities which are
unrated  or rated in the  lowest  rating  categories  by S&P or  Moody's.  These
lower-rated bonds are commonly referred to as junk bonds. Lower-rated securities
generally involve a higher risk of default than higher-rated ones.

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.

For  temporary,  defensive  purposes,  the  Series  may invest up to 100% of its
assets in U.S. Government  securities,  repurchase agreements  collateralized by
U.S.  Government  securities,   high-grade  commercial  paper,  certificates  of
deposit, bankers' acceptances, repurchase agreements,  non-convertible preferred
stocks,  non-convertible  corporate bonds with a remaining maturity of less than
one year, or subject to certain tax restrictions,  foreign currencies.  Taking a
defensive  position may reduce the  potential  for  appreciation  of the Series'
portfolio or for growth of income.

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 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  primarily  in  a
non-diversified  portfolio of equity  securities of U.S.  companies  with market
capitalizations  in the range of  companies  represented  in the Russell  MidCap
Index and that the sub-adviser believes are undervalued based on their return on
equity.  The Russell  MidCap  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.

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    Non-diversification.  The Series is  "non-diversified" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The Lazard/JNL Mid Cap Value Series invests  primarily in the equity  securities
of undervalued medium  capitalization U.S.  companies.  To the extent its assets
are not  invested  in such  securities,  the  Series  may  invest in the  equity
securities of large  capitalization  companies or  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 appreciates to over $5 billion. The sub-adviser's sell discipline
is driven  typically  by  whether,  in the  sub-adviser's  opinion,  a stock has
attained its fair valuation.

The  Series  may  use  derivative  instruments,  such  as  options  and  futures
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 large capitalization companies, cash and short-term money market instruments.
Taking a defensive  position may reduce the  potential for  appreciation  of the
Series' portfolio.

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  primarily  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.

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    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  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" as such term is
          defined in the Investment Company Act of 1940, as amended, which means
          that more than 5%, but not more than 25%,  of its total  assets may be
          invested in securities of any one issuer.  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.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The Lazard/JNL Small Cap Value Series invests in the equity  securities of small
capitalization companies that, in the sub-adviser's opinion, have one or more of
the following  characteristics:  (i) are undervalued  relative to their earnings
power,  cash flow,  and/or asset  values;  (ii) have an  attractive  price/value
relationship,   i.e.,   have  high   returns  on  equity   and/or   assets  with
correspondingly low price-to-book and/or price-to-asset value as compared to the
market  generally  or  the  companies'  industry  groups  in  particular,   with
expectations  that some  catalyst  will cause the  perception of value to change
within a 24-month  time horizon;  (iii) have  experienced  significant  relative
underperformance  and are out of favor due to a set of  circumstances  which are
unlikely to harm a company's  franchise or earnings  power over the longer term;
(iv)  have  low  projected  price-to-earnings  or  price-to-cash-flow  multiples
relative to their industry peer group and/or the market in general; (v) have the
prospect,  or the industry in which the company  operates has the  prospect,  to
become a larger  factor in the business and receive a higher  valuation as such;
(vi) have significant  financial leverage but have high levels of free cash flow
used to  reduce  leverage  and  enhance  shareholder  value;  and  (vii)  have a
relatively  short corporate  history with the expectation  that the business may
grow to generate meaningful cash flow and earnings over a reasonable  investment
horizon.  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.

The  sub-adviser  does  not   automatically   sell  a  security  if  its  market
capitalization appreciates to over $1 billion. The sub-adviser's sell discipline
is driven  typically  by  whether,  in the  sub-adviser's  opinion,  a stock has
attained its fair valuation.

The  Series  may  use  derivative  instruments,  such  as  options  and  futures
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 large 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.  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.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The PPM  America/JNL  Balanced  Series  invests  primarily in common  stocks and
fixed-income  securities  but may also  invest in  securities  convertible  into
common stocks, deferred debt obligations and zero coupon bonds.

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

For temporary, defensive purposes, the Series may invest up to all of its assets
in  cash  equivalents,  such  as  U.S.  Government  securities  and  high  grade
commercial  paper.  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

The Sub-Adviser and Portfolio Management

The  sub-adviser to the PPM  America/JNL  Balanced  Series is PPM America,  Inc.
(PPM), which is located at 225 West Wacker Drive, Chicago,  Illinois 60606. PPM,
an affiliate of the investment  adviser to the Trust,  manages assets of Jackson
National Life Insurance Company and of other affiliated companies.

PPM supervises  and manages the  investment  portfolio of the Series and directs

and sale  activity.  The teams adjust  holdings in the  portfolios  as they deem
appropriate  in the  pursuit  of the  Series'  investment  objectives.  PPM  has
supervised and managed the investment portfolio of the Series since May 1, 1997.

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.  These bonds,  commonly known as "junk bonds," are
those  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.

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    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    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.

          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    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. 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. 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 adviser's ability to effectively  implement the investment
strategies of the Series.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The PPM  America/JNL  High Yield Bond Series  invests the majority of its assets
under normal market conditions in U.S. corporate bonds of below investment-grade
quality and with maturities exceeding three years.  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 addition to investing in securities of foreign  issuers,  the Series may also
hold a portion  of its  assets in  foreign  currencies  and enter  into  forward
currency exchange  contracts,  currency options,  currency and financial futures
contracts,  and  options on such  futures  contracts.  The Series may enter into
repurchase agreements and firm commitment agreements and may purchase securities
on a  when-issued  basis.  The Series may invest  without  limit in zero  coupon
bonds.

The Series may adopt a temporary defensive position, such as investing up to all
of its assets in cash or cash  equivalents,  during adverse market,  economic or
other  circumstances  that the sub-adviser  believes require immediate action to
avoid  losses.  In doing so,  the  Series  may not be  pursuing  its  investment
objectives.

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

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 high  quality,  U.S.  dollar-denominated  money  market
instruments that mature in 397 days or less. 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. Because the Series invests in fixed-income  securities of
          U.S. and foreign  companies,  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.

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 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. 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. 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
to effectively implement the investment strategies of the Series.

Performance

The table below shows the performance of the Series and of the market indicators
listed since the Series began operation. The performance of the Series will vary
from year to year. As with all mutual funds,  the Series' past  performance does
not necessarily indicate how it will perform in the future.

Additional  Information  About  the  Principal  Investment   Strategies,   Other

options,  for  hedging  or  maturity  or  duration  purposes,  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.

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 Salomon Brothers/JNL  Balanced Series is Salomon Brothers

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 Series  seeks to  achieve  its  objective  through a  diversified  portfolio
consisting primarily of fixed income securities of U.S. and foreign issuers. The
sub-adviser invests the Series' assets primarily by making strategic allocations
among: U.S. investment grade bonds; high-yield bonds; non-U.S.  investment grade
bonds;  and  emerging  markets  debt  securities.  The  sub-adviser  makes these
allocations based on its analysis of current economic and market conditions, and
the relative risks and  opportunities,  applicable to those types of securities.
The  sub-adviser  may  invest a  significant  portion of the  Series'  assets in
medium- or lower-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.

     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. 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. 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    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.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The  Salomon  Brothers/JNL  Global  Bond  Series  invests 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  corporate  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.

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.

When the sub-adviser  believes that adverse conditions prevail in the market for
fixed-income  securities,  the Series may,  for  temporary  defensive  purposes,
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 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  Series  seeks  to  achieve  its  objectives  by  investing  primarily  in a
diversified portfolio of high- yield, high-risk, fixed-income securities of U.S.
issuers  rated in  medium  or lower  rating  categories  (or  determined  by the
sub-adviser  to be of  comparable  quality).  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.

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    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    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.

The table below shows the performance of the Series and of the market indicators

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

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.

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
issues.  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 partnerships 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.

The Sub-Adviser and Portfolio Management

The  sub-adviser to the Salomon  Brothers/JNL  High Yield Bond Series is Salomon

together  with  affiliates  in  London,  Frankfurt,  Tokyo and Hong  Kong,  SBAM
provides a broad range of fixed-income and equity  investment  advisory services
to various individual and institutional clients located throughout the world and
serves as sub-adviser to various investment companies.

Peter J. Wilby is primarily  responsible  for the  day-to-day  management of the
Series. Mr. Wilby has had primary  responsibility for the day-to-day  management
of the Series since the inception of the Series.  Mr. Wilby,  who joined SBAM in

Portfolio   Manager  of  SBAM,  is  responsible   for  investment   company  and
institutional  portfolios which invest in high-yield non-U.S. and U.S. corporate
debt securities and high-yield  foreign sovereign debt securities.  From 1984 to
1989, Mr. Wilby was employed by Prudential Capital Management Group (Prudential)
where he  served as  Director  of  Prudential's  credit  research  unit and as a
corporate and sovereign credit analyst with  Prudential.  Mr. Wilby also managed
high-yield  bonds and leveraged  equities in the mutual funds and  institutional
portfolios at Prudential.

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  Series  seeks  to  achieve  its  objective  by  investing  primarily  in  a
diversified portfolio of debt obligations and mortgage-backed  securities issued
or  guaranteed  by the  U.S.  Government,  its  agencies  or  instrumentalities,
including  collateralized  mortgage  obligations backed by such securities.  The
Series may also invest a portion of its assets in  investment  grade bonds.  The
Series may invest in  securities of any maturity or effective  duration,  so the
composition and weighted average maturity of the portfolio will vary.

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.

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

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

     o    U.S. Treasury obligations;

     o    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;

     o    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;

     o    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); and

     o    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.

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
average maturity and duration of mortgage-backed  derivative  securities may not
reflect the price volatility of those  securities in certain market  conditions.
The Series will not  knowingly  invest in any mortgage  security  that  exhibits
significantly  greater  price  volatility  than the  Fannie Mae  current  coupon
30-year, mortgage-backed pass-through security.

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 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.

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.

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

T. ROWE PRICE/JNL INTERNATIONAL EQUITY INVESTMENT SERIES

Investment Objective

The  investment  objective  of  the  T.  Rowe  Price/JNL   International  Equity
Investment Series is long-term growth of capital.

Principal Investment Strategies

The Series  seeks to  achieve  its  objective  through a  diversified  portfolio
consisting primarily of common stocks of established,  non-U.S.  companies.  The
Series  normally  has at least three  countries  represented  in its  portfolio,
including both developed and emerging markets.

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    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. 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. 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  market  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.

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

Additional  Information  About  the  Principal  Investment   Strategies,   Other
Investments and Risks of the Series

The T. Rowe Price/JNL  International Equity Investment Series invests in foreign
securities  that  the  sub-adviser  believes  offer  significant  potential  for
long-term  appreciation  and investment  diversification.  In addition to common
stocks,  the  Series  may also  invest  in other  types of  securities,  such as
preferred stocks, convertible securities, fixed-income securities.

In analyzing companies for investment,  the sub-adviser ordinarily looks for one
or more of the following  characteristics:  an above-average earnings growth per
share; high return on invested capital;  healthy balance sheet;  sound financial
and  accounting  policies and overall  financial  strength;  strong  competitive
advantages;  effective research and product development and marketing; efficient
service;  pricing  flexibility;  strength of management;  and general  operating
characteristics which will enable the companies to compete successfully in their
market place.  Current dividend income is not a prerequisite in the selection of
portfolio  companies.  However,  the Series generally  invests in companies that
have a record of paying dividends,  which the sub-adviser  expects will increase
in future years as earnings increase.

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.

strategies, as well as the risks and restrictions that may apply to them.

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  primarily  in  a
diversified  portfolio of common stock of medium-sized  (mid-cap) U.S. companies
which the sub-adviser  believes have the potential for  above-average  growth. A
mid-cap company is one 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.

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.

MORE ABOUT THE INVESTMENT OBJECTIVES AND RISKS OF ALL SERIES

The investment  objectives of the respective  Series are not fundamental and may
be changed by the Trustees without shareholder approval.

Year 2000 and Euro Issues:  Apart from the particular  risks described above for
each Series,  the Trust could be adversely affected if the computer systems used
by the Trust's  investment adviser and its other service providers are unable to
process and calculate  date-related  information because they are not programmed
to distinguish between the year 2000 and the year 1900.

The Trust relies entirely on outside service providers for the processing of its
business.  To the extent that a service provider  utilizes  computers to process
the Trust's  business,  the smooth operation of the Trust depends on the ability
of those computers to continue to function properly.

The Trust has contacted  each of its service  providers to ascertain the service
provider's  state of readiness for the year 2000. Each of the service  providers
has indicated to the Trust that, at this time, it is either year 2000  compliant
or that  it has  identified  its  systems  which  are not  currently  year  2000
compliant and that it intends to make such systems compliant before December 31,
1999.  The Trust  intends to  continue  to monitor  the year 2000  status of its
service providers.

Based on the information currently available,  the Trust does not anticipate any
material impact on the delivery of services to and by the Trust. However,  since
the Trust must rely on the information  provided to it by its service providers,
there can be no  assurance  that the steps  taken by the  service  providers  in
preparation  for the year 2000 will be sufficient to avoid any adverse impact on
the Trust.

Similarly,  the companies  and other issuers in which a Series  invests could be
adversely affected by year 2000 computer-related  problems,  and there can be no
assurance  that the steps taken,  if any, by these issuers will be sufficient to
avoid any adverse impact on the Series.

Also,  to the extent  that a Series  invests in foreign  securities,  the Series
could be adversely  affected by the  conversion of certain  European  currencies
into the Euro. This conversion,  which is underway, is scheduled to be completed
in 2002. However, problems with the conversion process and delays could increase
volatility  in world  capital  markets and affect  European  capital  markets in
particular.

MANAGEMENT OF THE TRUST

Investment Adviser

Under  Massachusetts law and the Trust's  Declaration of Trust and By-Laws,  the
management of the business and affairs of the Trust is the responsibility of the
Trustees.  Jackson National Financial  Services,  LLC (JNFSLLC),  5901 Executive
Drive,  Lansing,  Michigan  48911,  is the  investment  adviser to the Trust and
provides the Trust with  professional  investment  supervision  and  management.
Jackson National  Financial  Services,  Inc. served as investment adviser to the
Trust from the  inception of the Trust until July 1, 1998,  when it  transferred
its duties as  investment  adviser  and its  professional  staff for  investment
advisory services to JNFSLLC.

Management Fee

As compensation for its services, JNFSLLC receives a fee from the Trust computed
separately  for each Series,  accrued daily and payable  monthly.  The fee which
JNFSLLC  received from each Series for the fiscal year ended  December 31, 1998,
is set forth below as an annual percentage of the net assets of the Series.  For
a Series which was not in operation for all of 1998, its current  management fee
schedule is shown instead. Each JNL/S&P Series will indirectly bear its pro rata
share of fees of the  Underlying  Series in  addition to the fees shown for that
Series.

Sub-Advisory Arrangements

JNFSLLC  selects,  contracts  with and  compensates  sub-advisers  to manage the
investment and  reinvestment  of the assets of the Series of the Trust.  JNFSLLC
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  JNFSLLC,  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 JNFSLLC 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 JNFSLLC
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 JNFSLLC  currently is obligated to pay the sub-advisers out of the advisory
fee it receives from the Series.

ADMINISTRATIVE FEE

In addition to the  investment  advisory fee,  effective  January 1, 1999,  each
Series,  except the  JNL/SSGA  Enhanced  Intermediate  Bond Index Series and the
JNL/S&P  Series,  pays to JNFSLLC an  Administrative  Fee of .10% of the average
daily net assets of the Series.  The JNL/SSGA  Enhanced  Intermediate Bond Index
Series pays an  Administrative  Fee of .20%.  The  JNL/S&P  Series do not pay an
Administrative  Fee. In return for the fee,  JNFSLLC  provides  or procures  all
necessary administrative functions and services for the operation of the Series.
In addition,  JNFSLLC,  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.  Prior to January 1, 1999,  each Series paid all of its own  operating
expenses.

INVESTMENT IN TRUST SHARES

Shares  of the Trust are  currently  sold to  separate  accounts  (Accounts)  of
Jackson National Life Insurance Company, 5901 Executive Drive, Lansing, Michigan
48911, 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).  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,  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  (Trust)  is an  open-end  management  investment
company  organized  under the laws 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.  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 bear directly 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. CMOs
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).

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.  These include
non-U.S.  dollar-denominated  securities traded principally outside the U.S. and
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).  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  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 contract,  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.

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 is 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).  The REITs in which a Series may invest
include  equity REITs,  which own real estate  properties,  and mortgage  REITs,
which make construction,  development and long-term mortgage 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,  self-liquidation,  failure
to qualify as a  "pass-through"  entity  under the Federal  tax law,  failure to
qualify as an exempt entity under the Investment Company Act of 1940, as amended
(1940 Act), and the fact that REITs are not diversified.

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.

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.  Standard & Poor's  Depository  Receipts
(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.  This 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 these 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.

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:
(1) the risk that interest rates,  securities  prices and currency  markets will
not move in the directions  anticipated;  (2) imperfect  correlation between the
price of derivative  instruments  and movements in the prices of the securities,
interest  rates or currencies  being hedged;  (3) the fact that skills needed to
use these  strategies  are  different  from  those  needed  to select  portfolio
securities;  (4) the  possible  absence  of a liquid  secondary  market  for any
particular  instrument  at any time;  and (5) 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.


                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  Capital  Growth  Series,  JNL/S&P

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.

         (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

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

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.

Insurance Law  Restrictions.  In connection  with the Trust's  agreement to sell

(JNFSLLC) and the insurance  companies  may enter into  agreements,  required by
certain state  insurance  departments,  under which JNFSLLC may agree to use its
best  efforts to assure and to permit  insurance  companies to monitor that each
Series of the Trust complies with the investment  restrictions  and  limitations
prescribed by state insurance laws and regulations  applicable to the investment
of separate  account  assets in shares of mutual  funds.  If a Series  failed to
comply with such  restrictions or limitations,  the insurance company would take
appropriate action which might include ceasing to make investments in the Series

operations.

                                   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 (except
the PPM  America/JNL  Money  Market  Series)  for the periods  indicated  was as
follows:

         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, 1998,  for each of
the referenced Series was as follows:

    JNL/PIMCO Total Return Bond Series                                  %
    PPM America/JNL Balanced Series                                     %
    PPM America/JNL High-yield Bond Series                              %
    Salomon Brothers/JNL Global Bond Series                             %
    Salomon Brothers/JNL Global Bond Series                             %
    Salomon Brothers/JNL U.S. Government & Quality Bond Series          %

         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, 1998, was ____%.

         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, 1998, was ____%.

         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  World Index,  the
Lehman Brothers Aggregate Bond Index, the Lehman Brothers  High-yield Index, the
Salomon Brothers Broad  Investment  Grade Index,  the Salomon Brothers  Treasury
Index,  the Russell 2000 Index,  the Russell Midcap Index, or the Morgan Stanley
Europe and Australasia, Far East Equity 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 JNFSLLC  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 JNFSLLC  and the  Trustees  pursuant to
investment  sub-advisory agreements entered into between JNFSLLC 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 JNFSLLC 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).

Administrative Fee. Effective January 1, 1999, each Series,  except the JNL/SSGA
Enhanced  Intermediate Bond Index Series and each of the JNL/S&P Series, pays to
JNFSLLC an  Administrative  Fee of .10% of the  average  daily net assets of the
Series.   The  JNL/SSGA   Enhanced   Intermediate  Bond  Index  Series  pays  an
Administrative Fee of .20%. The JNL/S&P Series do not pay an Administrative Fee.
In return for the fee, JNFSLLC provides or procures all necessary administrative
functions and services for the operation of the Series. In addition, JNFSLLC, 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.
Prior to January 1, 1999,  each Series paid all of its own  operating  expenses.
Each Series is responsible for trading expenses including brokerage commissions,
interest and taxes, and other non-operating expenses.

Custodian and Transfer  Agent.  The custodian has custody of all  securities and
cash of the Trust  maintained in the United States and attends to the collection
of principal and income and payment for and collection of proceeds of securities
bought and sold by the Trust.

         JNFSLLC is the transfer agent and dividend-paying agent for each Series
of the Trust.

Independent     Accountants.     The    Series'     independent     accountants,
PricewaterhouseCoopers  LLP, 200 East Randolph Drive,  Chicago,  Illinois 60601,
audit and report on the Series' annual financial  statements,  and perform other
professional accounting, auditing and advisory services when engaged to do so by
the Series.

Series  Transactions  and  Brokerage.  The primary  consideration  in  portfolio
security transactions is "best execution," i.e., execution at the most favorable
prices and in the most effective manner  possible.  JNFSLLC and the sub-advisers
always  attempt to achieve best  execution and have  complete  freedom as to the
markets in and the broker/dealers  through which they seek this result.  Subject
to the requirement of seeking best  execution,  securities may be bought from or
sold to  broker/dealers  who have  furnished  statistical,  research,  and other
information or services to JNFSLLC or the  sub-advisers.  In placing orders with
such  broker/dealers,  JNFSLLC and the sub-advisers  will, where possible,  take
into account the comparative usefulness of such information. Such information is
useful to JNFSLLC  and the  sub-advisers  even  though  its dollar  value may be
indeterminable  and its  receipt  or  availability  generally  does  not  reduce
JNFSLLC's or the sub-advisers' normal research activities or expenses.

         Trust portfolio  transactions may be effected with  broker/dealers  who
have  assisted  investors in the purchase of  Contracts.  However,  neither such
assistance  nor sale of other  investment  company  shares  is a  qualifying  or
disqualifying factor in a broker/dealer's selection, nor is the selection of any
broker/dealer based on the volume of shares sold.

         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 JNFSLLC
or the sub-advisers.  Although such concurrent authorizations  potentially could
be either  advantageous or  disadvantageous to the Trust, they are effected only
when  JNFSLLC 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,  JNFSLLC  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.

                  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 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

COMMERCIAL PAPER RATINGS

A-1, A-2 AND PRIME-1, PRIME-2 COMMERCIAL PAPER RATINGS

    Commercial  paper rated by Standard & Poor's,  a division of The McGraw-Hill
Companies, Inc. (Standard & Poor's) has the following characteristics: Liquidity
ratios are adequate to meet cash  requirements.  Long-term  senior debt is rated
"A" or better.  The issuer has  access to at least two  additional  channels  of
borrowing. Basic earnings and cash flow have an upward trend with allowance made
for unusual circumstances.  Typically, the issuer's industry is well established
and the issuer has a strong  position  within the industry.  The reliability and
quality of management  are  unquestioned.  Relative  strength or weakness of the
above factors  determine  whether the issuer's  commercial paper is rated A-1 or
A-2.

    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.

CORPORATE BONDS

STANDARD & POOR'S BOND RATINGS

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

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

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

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

    BB, B, CCC, CC, C. Debt rated BB, B, CCC, CC, and C is regarded, on balance,
as predominantly  speculative with respect to capacity to pay interest and repay
principal in  accordance  with the terms of the  obligation.  BB  indicates  the
lowest degree of speculation and C the highest degree of speculation. While such
debt will likely have some  quality and  protective  characteristics,  these are
outweighed by large uncertainties or major risk exposures to adverse conditions.

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

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

MOODY'S 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.

         Not Applicable.

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.

Administrator  reasonable  opportunity  to defend  against such claim in its own
name or the name of the Series.

14.  EFFECT OF AGREEMENT
