                               JNL(R) SERIES TRUST

The prospectus is also being amended by inserting the following new paragraph at
the end of the section of the prospectus entitled "Sub-Advisory Arrangements":

The  Investment  Adviser  and the Trust has  filed an  application  to obtain an
exemption  from the  Securities  and  Exchange  Commission  for a  multi-manager
structure  that  allows the  Investment  Adviser to hire,  replace or  terminate
sub-advisers  without the approval of  shareholders.  The order would also allow
the Investment  Adviser to revise a sub-advisory  agreement with the approval of
the Board of Trustees, but without shareholder approval. If a new sub-adviser is
hired, shareholders will receive information about the new sub-adviser within 90
days of the change. The order would allow the Series to operate more efficiently
and with greater  flexibility.  The  Investment  Adviser  provides the following
oversight and evaluation services to the Series:

o    performing initial due diligence on prospective sub-advisers for the Series
o    monitoring the performance of sub-advisers
o    communicating performance expectations to the sub-advisers
o    ultimately  recommending  to the Board of Trustees  whether a sub-adviser's
     contract should be renewed, modified or terminated.

The  Investment  Adviser  does not  expect  to  recommend  frequent  changes  of
sub-advisers.  Although the Investment  Adviser will monitor the  performance of
the  sub-advisers,  there is no certainty  that any  sub-adviser  or Series will
obtain  favorable  results at any given time.  At a  shareholder  meeting of the
Trust  held  on  October  26,  2000,  all  Series  approved  this  multi-manager
structure.

Certain series of the JNL Series Trust (the "Trust") have adopted a Distribution
Plan under Rule 12b-1 of the  Investment  Company Act of 1940,  as amended  (the
"1940 Act").  Accordingly,  the Prospectus is amended by inserting the following
section after the paragraph  entitled  "Administrative  Fee" which is located in
the "Management of the Trust " section of the prospectus:

                           BROKERAGE ENHANCEMENT PLAN

At a  shareholder  meeting  of the Trust held on October  26,  2000,  all series
except the PPM  America/JNL  Money Market Series and each of the JNL/S&P  Series
adopted,  in accordance  with the provisions of Rule 12b-1 under the 1940 Act, a
Brokerage  Enhancement  Plan (the  "Plan").  The Plan uses  available  brokerage
commissions to promote the sale and  distribution  of Trust shares  (through the
sale of variable insurance products funded by the Trust).


The Plan  authorizes  the  Trust to place  orders  for the  purchase  or sale of
portfolio  securities or other assets with: (i) broker-dealers  that have agreed
to  direct a portion  of their  brokerage  commissions  to  introducing  brokers
("Brokerage  Payments")  to be used to  finance  activities  that are  primarily
intended  to result in the sale of Trust  shares  through  the sale of  Variable
Contracts;  and (ii)  broker-dealers  that,  in addition to executing the trade,
will provide brokerage credits, benefits or other services ("Brokerage Credits")
to be used directly or indirectly  to promote the  distribution  of Trust shares
through the sale of Variable  Contracts.  Management  of JNFS has  informed  the
Board of Trustees of the Trust that  brokerage  commission  rates and commission
amounts paid by the various  Series of the Trust are NOT expected to increase as
a result of the  implementation  of the Plan.  As part of the Plan,  JNLD  would
become the principal  underwriter  of the Series of the Trust adopting the Plan,
with responsibility for promoting sales of shares of such Series.

Under the Plan, JNFS or a Sub-Adviser, would, subject to the requirement to seek
best price and execution,  effect brokerage transactions in portfolio securities
through broker-dealers. It is anticipated that activities or services which will
be procured through Brokerage  Payments and Brokerage Credits given to JNLD will
include:

o    Developing,  preparing,  printing,  and  mailing of  advertisements,  sales
     literature and other promotional material describing and/or relating to the
     Trust, the Series, or the Variable Contracts.

o    Printing  and  mailing  of Trust  prospectuses,  statements  of  additional
     information,   any  supplements   thereto  and   shareholder   reports  for
     prospective Variable Contract owners.

o    Holding or participating in seminars and sales meetings designed to promote
     the  distribution  of  shares of the  Trust,  the  Series  or the  Variable
     Contracts,  including  materials intended either for broker-dealer only use
     or for retail use.

o    Providing   information  about  the  Trust,  its  Series  or  the  Variable
     Contracts,  or mutual funds or variable contracts in general, to registered
     representatives of broker-dealers.

o    Providing assistance to broker-dealers that are conducting due diligence on
     the Trust or its Series or the Variable Contracts.

o Payment of marketing fees or allowances  requested by broker-dealers  who sell
Variable Contracts.

o    Obtaining  information  and  providing  explanations  to Variable  Contract
     owners  regarding  Series   investment   options  and  policies  and  other
     information  about the Trust and its Series,  including the  performance of
     the Series.

o Training sales personnel regarding sales of Variable Contracts.

o Personal service and/or maintenance of the Variable Contract owner accounts.

o Financing  any other  activity that is intended to result in the sale of Trust
shares or the Variable Contracts.

The Plan  permits the  Brokerage  Payments and Credits  generated by  securities
transactions  from one  series  of the  Trust to inure to the  benefit  of other
Series as well. The Plan is not expected to increase the brokerage  costs of the
Trust.  For  more  information  about  the  Plan,  please  read  the  "Brokerage
Enhancement Plan" section of the Statement of Additional Information.

              SUPPLEMENT TO THE PROSPECTUS DATED DECEMBER 18, 2000

               PERSPECTIVE ADVISORS FIXED AND VARIABLE ANNUITY (R)

                               JNL(R) SERIES TRUST

The prospectus is also being amended by inserting the following new paragraph at
the end of the section of the prospectus entitled "Sub-Advisory Arrangements":

The  Investment  Adviser  and the Trust has  filed an  application  to obtain an
exemption  from the  Securities  and  Exchange  Commission  for a  multi-manager
structure  that  allows the  Investment  Adviser to hire,  replace or  terminate
sub-advisers  without the approval of  shareholders.  The order would also allow
the Investment  Adviser to revise a sub-advisory  agreement with the approval of
the Board of Trustees, but without shareholder approval. If a new sub-adviser is
hired, shareholders will receive information about the new sub-adviser within 90
days of the change. The order would allow the Series to operate more efficiently
and with greater  flexibility.  The  Investment  Adviser  provides the following
oversight and evaluation services to the Series:

o    performing initial due diligence on prospective sub-advisers for the Series
o    monitoring the performance of sub-advisers
o    communicating performance expectations to the sub-advisers
o    ultimately  recommending  to the Board of Trustees  whether a sub-adviser's
     contract should be renewed, modified or terminated.

The  Investment  Adviser  does not  expect  to  recommend  frequent  changes  of
sub-advisers.  Although the Investment  Adviser will monitor the  performance of
the  sub-advisers,  there is no certainty  that any  sub-adviser  or Series will
obtain  favorable  results at any given time.  At a  shareholder  meeting of the
Trust  held  on  October  26,  2000,  all  Series  approved  this  multi-manager
structure.

Certain series of the JNL Series Trust (the "Trust") have adopted a Distribution
Plan under Rule 12b-1 of the  Investment  Company Act of 1940,  as amended  (the
"1940 Act").  Accordingly,  the Prospectus is amended by inserting the following
section after the paragraph  entitled  "Administrative  Fee" which is located in
the "Management of the Trust " section of the prospectus:

                           BROKERAGE ENHANCEMENT PLAN


At a  shareholder  meeting  of the Trust held on October  26,  2000,  all series
except the PPM  America/JNL  Money Market Series and each of the JNL/S&P  Series
adopted,  in accordance  with the provisions of Rule 12b-1 under the 1940 Act, a
Brokerage  Enhancement  Plan (the  "Plan").  The Plan uses  available  brokerage
commissions to promote the sale and  distribution  of Trust shares  (through the
sale of variable insurance products funded by the Trust).


The Plan  authorizes  the  Trust to place  orders  for the  purchase  or sale of
portfolio  securities or other assets with: (i) broker-dealers  that have agreed
to  direct a portion  of their  brokerage  commissions  to  introducing  brokers
("Brokerage  Payments")  to be used to  finance  activities  that are  primarily
intended  to result in the sale of Trust  shares  through  the sale of  Variable
Contracts;  and (ii)  broker-dealers  that,  in addition to executing the trade,
will provide brokerage credits, benefits or other services ("Brokerage Credits")
to be used directly or indirectly  to promote the  distribution  of Trust shares
through the sale of Variable  Contracts.  Management  of JNFS has  informed  the
Board of Trustees of the Trust that  brokerage  commission  rates and commission
amounts paid by the various  Series of the Trust are NOT expected to increase as
a result of the  implementation  of the Plan.  As part of the Plan,  JNLD  would
become the principal  underwriter  of the Series of the Trust adopting the Plan,
with responsibility for promoting sales of shares of such Series.

Under the Plan, JNFS or a Sub-Adviser, would, subject to the requirement to seek
best price and execution,  effect brokerage transactions in portfolio securities
through broker-dealers. It is anticipated that activities or services which will
be procured through Brokerage  Payments and Brokerage Credits given to JNLD will
include:

o    Developing,  preparing,  printing,  and  mailing of  advertisements,  sales
     literature and other promotional material describing and/or relating to the
     Trust, the Series, or the Variable Contracts.

o    Printing  and  mailing  of Trust  prospectuses,  statements  of  additional
     information,   any  supplements   thereto  and   shareholder   reports  for
     prospective Variable Contract owners.

o    Holding or participating in seminars and sales meetings designed to promote
     the  distribution  of  shares of the  Trust,  the  Series  or the  Variable
     Contracts,  including  materials intended either for broker-dealer only use
     or for retail use.

o    Providing   information  about  the  Trust,  its  Series  or  the  Variable
     Contracts,  or mutual funds or variable contracts in general, to registered
     representatives of broker-dealers.

o    Providing assistance to broker-dealers that are conducting due diligence on
     the Trust or its Series or the Variable Contracts.

o    Payment of marketing  fees or allowances  requested by  broker-dealers  who
     sell Variable Contracts.

o    Obtaining  information  and  providing  explanations  to Variable  Contract
     owners  regarding  Series   investment   options  and  policies  and  other
     information  about the Trust and its Series,  including the  performance of
     the Series.

o    Training sales personnel regarding sales of Variable Contracts.

o    Personal  service  and/or   maintenance  of  the  Variable  Contract  owner
     accounts.

o    Financing  any other  activity  that is  intended  to result in the sale of
     Trust shares or the Variable Contracts.

The Plan  permits the  Brokerage  Payments and Credits  generated by  securities
transactions  from one  series  of the  Trust to inure to the  benefit  of other
Series as well. The Plan is not expected to increase the brokerage  costs of the
Trust.  For  more  information  about  the  Plan,  please  read  the  "Brokerage
Enhancement Plan" section of the Statement of Additional Information.

              SUPPLEMENT TO THE PROSPECTUS DATED DECEMBER 18, 2000

         JACKSON NATIONAL LIFE(R) DEFINED STRATEGIES VARIABLE ANNUITY sm

                               JNL(R) SERIES TRUST

The prospectus is also being amended by inserting the following new paragraph at
the end of the section of the prospectus entitled "Sub-Advisory Arrangements":

The  Investment  Adviser  and the Trust has  filed an  application  to obtain an
exemption  from the  Securities  and  Exchange  Commission  for a  multi-manager
structure  that  allows the  Investment  Adviser to hire,  replace or  terminate
sub-advisers  without the approval of  shareholders.  The order would also allow
the Investment  Adviser to revise a sub-advisory  agreement with the approval of
the Board of Trustees, but without shareholder approval. If a new sub-adviser is
hired, shareholders will receive information about the new sub-adviser within 90
days of the change. The order would allow the Series to operate more efficiently
and with greater  flexibility.  The  Investment  Adviser  provides the following
oversight and evaluation services to the Series:

o    performing initial due diligence on prospective sub-advisers for the Series
o    monitoring the performance of sub-advisers
o    communicating performance expectations to the sub-advisers
o    ultimately  recommending  to the Board of Trustees  whether a sub-adviser's
     contract should be renewed, modified or terminated.

The  Investment  Adviser  does not  expect  to  recommend  frequent  changes  of
sub-advisers.  Although the Investment  Adviser will monitor the  performance of
the  sub-advisers,  there is no certainty  that any  sub-adviser  or Series will
obtain  favorable  results at any given time.  At a  shareholder  meeting of the
Trust  held  on  October  26,  2000,  all  Series  approved  this  multi-manager
structure.

Certain series of the JNL Series Trust (the "Trust") have adopted a Distribution
Plan under Rule 12b-1 of the  Investment  Company Act of 1940,  as amended  (the
"1940 Act").  Accordingly,  the Prospectus is amended by inserting the following
section after the paragraph  entitled  "Administrative  Fee" which is located in
the "Management of the Trust " section of the prospectus:

                           BROKERAGE ENHANCEMENT PLAN

At a  shareholder  meeting  of the Trust held on October  26,  2000,  all series
except the PPM  America/JNL  Money Market Series and each of the JNL/S&P  Series
adopted,  in accordance  with the provisions of Rule 12b-1 under the 1940 Act, a
Brokerage  Enhancement  Plan (the  "Plan").  The Plan uses  available  brokerage
commissions to promote the sale and  distribution  of Trust shares  (through the
sale of variable insurance products funded by the Trust).

The Plan  authorizes  the  Trust to place  orders  for the  purchase  or sale of
portfolio  securities or other assets with: (i) broker-dealers  that have agreed
to  direct a portion  of their  brokerage  commissions  to  introducing  brokers
("Brokerage  Payments")  to be used to  finance  activities  that are  primarily
intended  to result in the sale of Trust  shares  through  the sale of  Variable
Contracts;  and (ii)  broker-dealers  that,  in addition to executing the trade,
will provide brokerage credits, benefits or other services ("Brokerage Credits")
to be used directly or indirectly  to promote the  distribution  of Trust shares
through the sale of Variable  Contracts.  Management  of JNFS has  informed  the
Board of Trustees of the Trust that  brokerage  commission  rates and commission
amounts paid by the various  Series of the Trust are NOT expected to increase as
a result of the  implementation  of the Plan.  As part of the Plan,  JNLD  would
become the principal  underwriter  of the Series of the Trust adopting the Plan,
with responsibility for promoting sales of shares of such Series.

Under the Plan, JNFS or a Sub-Adviser, would, subject to the requirement to seek
best price and execution,  effect brokerage transactions in portfolio securities
through broker-dealers. It is anticipated that activities or services which will
be procured through Brokerage  Payments and Brokerage Credits given to JNLD will
include:

o    Developing,  preparing,  printing,  and  mailing of  advertisements,  sales
     literature and other promotional material describing and/or relating to the
     Trust, the Series, or the Variable Contracts.

o    Printing  and  mailing  of Trust  prospectuses,  statements  of  additional
     information,   any  supplements   thereto  and   shareholder   reports  for
     prospective Variable Contract owners.

o    Holding or participating in seminars and sales meetings designed to promote
     the  distribution  of  shares of the  Trust,  the  Series  or the  Variable
     Contracts,  including  materials intended either for broker-dealer only use
     or for retail use.

o    Providing   information  about  the  Trust,  its  Series  or  the  Variable
     Contracts,  or mutual funds or variable contracts in general, to registered
     representatives of broker-dealers.

o    Providing assistance to broker-dealers that are conducting due diligence on
     the Trust or its Series or the Variable Contracts.

o Payment of marketing fees or allowances  requested by broker-dealers  who sell
Variable Contracts.

o    Obtaining  information  and  providing  explanations  to Variable  Contract
     owners  regarding  Series   investment   options  and  policies  and  other
     information  about the Trust and its Series,  including the  performance of
     the Series.

o Training sales personnel regarding sales of Variable Contracts.

o Personal service and/or maintenance of the Variable Contract owner accounts.

o Financing  any other  activity that is intended to result in the sale of Trust
shares or the Variable Contracts.

The Plan  permits the  Brokerage  Payments and Credits  generated by  securities
transactions  from one  series  of the  Trust to inure to the  benefit  of other
Series as well. The Plan is not expected to increase the brokerage  costs of the
Trust.  For  more  information  about  the  Plan,  please  read  the  "Brokerage
Enhancement Plan" section of the Statement of Additional Information.

The  Investment  Adviser  and the Trust has  filed an  application  to obtain an
exemption  from the  Securities  and  Exchange  Commission  for a  multi-manager
structure  that  allows the  Investment  Adviser to hire,  replace or  terminate
sub-advisers  without the approval of  shareholders.  The order would also allow
the Investment  Adviser to revise a sub-advisory  agreement with the approval of
the Board of Trustees, but without shareholder approval. If a new sub-adviser is
hired, shareholders will receive information about the new sub-adviser within 90
days of the change. The order would allow the Series to operate more efficiently
and with greater  flexibility.  The  Investment  Adviser  provides the following
oversight and evaluation services to the Series:

o    performing initial due diligence on prospective sub-advisers for the Series

o    monitoring the performance of sub-advisers

o    communicating performance expectations to the sub-advisers

o    ultimately  recommending  to the Board of Trustees  whether a sub-adviser's
     contract should be renewed, modified or terminated.

The  Investment  Adviser  does not  expect  to  recommend  frequent  changes  of
sub-advisers.  Although the Investment  Adviser will monitor the  performance of
the  sub-advisers,  there is no certainty  that any  sub-adviser  or Series will
obtain  favorable  results at any given time.  At a  shareholder  meeting of the
Trust  held  on  October  26,  2000,  all  Series  approved  this  multi-manager
structure.

Certain series of the JNL Series Trust (the "Trust") have adopted a Distribution
Plan under Rule 12b-1 of the  Investment  Company Act of 1940,  as amended  (the
"1940 Act").  Accordingly,  the Prospectus is amended by inserting the following
section after the paragraph  entitled  "Administrative  Fee" which is located in
the "Management of the Trust " section of the prospectus:

                           BROKERAGE ENHANCEMENT PLAN

At a  shareholder  meeting  of the Trust held on October  26,  2000,  all series
except the PPM  America/JNL  Money Market Series and each of the JNL/S&P  Series
adopted,  in accordance  with the provisions of Rule 12b-1 under the 1940 Act, a
Brokerage  Enhancement  Plan (the  "Plan").  The Plan uses  available  brokerage
commissions to promote the sale and  distribution  of Trust shares  (through the
sale of variable insurance products funded by the Trust).


The Plan  authorizes  the  Trust to place  orders  for the  purchase  or sale of
portfolio  securities or other assets with: (i) broker-dealers  that have agreed
to  direct a portion  of their  brokerage  commissions  to  introducing  brokers
("Brokerage  Payments")  to be used to  finance  activities  that are  primarily
intended  to result in the sale of Trust  shares  through  the sale of  Variable
Contracts;  and (ii)  broker-dealers  that,  in addition to executing the trade,
will provide brokerage credits, benefits or other services ("Brokerage Credits")
to be used directly or indirectly  to promote the  distribution  of Trust shares
through the sale of Variable  Contracts.  Management  of JNFS has  informed  the
Board of Trustees of the Trust that  brokerage  commission  rates and commission
amounts paid by the various  Series of the Trust are NOT expected to increase as
a result of the  implementation  of the Plan.  As part of the Plan,  JNLD  would
become the principal  underwriter  of the Series of the Trust adopting the Plan,
with responsibility for promoting sales of shares of such Series.

Under the Plan, JNFS or a Sub-Adviser, would, subject to the requirement to seek
best price and execution,  effect brokerage transactions in portfolio securities
through broker-dealers. It is anticipated that activities or services which will
be procured through Brokerage  Payments and Brokerage Credits given to JNLD will
include:

o    Developing,  preparing,  printing,  and  mailing of  advertisements,  sales
     literature and other promotional material describing and/or relating to the
     Trust, the Series, or the Variable Contracts.

o    Printing  and  mailing  of Trust  prospectuses,  statements  of  additional
     information,   any  supplements   thereto  and   shareholder   reports  for
     prospective Variable Contract owners.

o    Holding or participating in seminars and sales meetings designed to promote
     the  distribution  of  shares of the  Trust,  the  Series  or the  Variable
     Contracts,  including  materials intended either for broker-dealer only use
     or for retail use.

o    Providing   information  about  the  Trust,  its  Series  or  the  Variable
     Contracts,  or mutual funds or variable contracts in general, to registered
     representatives of broker-dealers.

o    Providing assistance to broker-dealers that are conducting due diligence on
     the Trust or its Series or the Variable Contracts.

o    Payment of marketing  fees or allowances  requested by  broker-dealers  who
     sell Variable Contracts.

o    Obtaining  information  and  providing  explanations  to Variable  Contract
     owners  regarding  Series   investment   options  and  policies  and  other
     information  about the Trust and its Series,  including the  performance of
     the Series.

o    Training sales personnel regarding sales of Variable Contracts.

o    Personal  service  and/or   maintenance  of  the  Variable  Contract  owner
     accounts.

o    Financing  any other  activity  that is  intended  to result in the sale of
     Trust shares or the Variable Contracts.

The Plan  permits the  Brokerage  Payments and Credits  generated by  securities
transactions  from one  series  of the  Trust to inure to the  benefit  of other
Series as well. The Plan is not expected to increase the brokerage  costs of the
Trust.  For  more  information  about  the  Plan,  please  read  the  "Brokerage
Enhancement Plan" section of the Statement of Additional Information.

              SUPPLEMENT TO THE PROSPECTUS DATED DECEMBER 18, 2000

             PERSPECTIVE ADVISORS FIXED AND VARIABLE ANNUITY(R)(NY)

                               JNL(R) SERIES TRUST

The prospectus is also being amended by inserting the following new paragraph at
the end of the section of the prospectus entitled "Sub-Advisory Arrangements":

The  Investment  Adviser  and the Trust has  filed an  application  to obtain an
exemption  from the  Securities  and  Exchange  Commission  for a  multi-manager
structure  that  allows the  Investment  Adviser to hire,  replace or  terminate
sub-advisers  without the approval of  shareholders.  The order would also allow
the Investment  Adviser to revise a sub-advisory  agreement with the approval of
the Board of Trustees, but without shareholder approval. If a new sub-adviser is
hired, shareholders will receive information about the new sub-adviser within 90
days of the change. The order would allow the Series to operate more efficiently
and with greater  flexibility.  The  Investment  Adviser  provides the following
oversight and evaluation services to the Series:

o    performing initial due diligence on prospective sub-advisers for the Series
o    monitoring the performance of sub-advisers
o    communicating performance expectations to the sub-advisers
o    ultimately  recommending  to the Board of Trustees  whether a sub-adviser's
     contract should be renewed, modified or terminated.

The  Investment  Adviser  does not  expect  to  recommend  frequent  changes  of
sub-advisers.  Although the Investment  Adviser will monitor the  performance of
the  sub-advisers,  there is no certainty  that any  sub-adviser  or Series will
obtain  favorable  results at any given time.  At a  shareholder  meeting of the
Trust  held  on  October  26,  2000,  all  Series  approved  this  multi-manager
structure.

Certain series of the JNL Series Trust (the "Trust") have adopted a Distribution
Plan under Rule 12b-1 of the  Investment  Company Act of 1940,  as amended  (the
"1940 Act").  Accordingly,  the Prospectus is amended by inserting the following
section after the paragraph  entitled  "Administrative  Fee" which is located in
the "Management of the Trust " section of the prospectus:

                           BROKERAGE ENHANCEMENT PLAN

At a  shareholder  meeting  of the Trust held on October  26,  2000,  all series
except the PPM  America/JNL  Money Market Series and each of the JNL/S&P  Series
adopted,  in accordance  with the provisions of Rule 12b-1 under the 1940 Act, a
Brokerage  Enhancement  Plan (the  "Plan").  The Plan uses  available  brokerage
commissions to promote the sale and  distribution  of Trust shares  (through the
sale of variable insurance products funded by the Trust).

The Plan  authorizes  the  Trust to place  orders  for the  purchase  or sale of
portfolio  securities or other assets with: (i) broker-dealers  that have agreed
to  direct a portion  of their  brokerage  commissions  to  introducing  brokers
("Brokerage  Payments")  to be used to  finance  activities  that are  primarily
intended  to result in the sale of Trust  shares  through  the sale of  Variable
Contracts;  and (ii)  broker-dealers  that,  in addition to executing the trade,
will provide brokerage credits, benefits or other services ("Brokerage Credits")
to be used directly or indirectly  to promote the  distribution  of Trust shares
through the sale of Variable  Contracts.  Management  of JNFS has  informed  the
Board of Trustees of the Trust that  brokerage  commission  rates and commission
amounts paid by the various  Series of the Trust are NOT expected to increase as
a result of the  implementation  of the Plan.  As part of the Plan,  JNLD  would
become the principal  underwriter  of the Series of the Trust adopting the Plan,
with responsibility for promoting sales of shares of such Series.

Under the Plan, JNFS or a Sub-Adviser, would, subject to the requirement to seek
best price and execution,  effect brokerage transactions in portfolio securities
through broker-dealers. It is anticipated that activities or services which will
be procured through Brokerage  Payments and Brokerage Credits given to JNLD will
include:

o    Developing,  preparing,  printing,  and  mailing of  advertisements,  sales
     literature and other promotional material describing and/or relating to the
     Trust, the Series, or the Variable Contracts.

o    Printing  and  mailing  of Trust  prospectuses,  statements  of  additional
     information,   any  supplements   thereto  and   shareholder   reports  for
     prospective Variable Contract owners.

o    Holding or participating in seminars and sales meetings designed to promote
     the  distribution  of  shares of the  Trust,  the  Series  or the  Variable
     Contracts,  including  materials intended either for broker-dealer only use
     or for retail use.

o    Providing   information  about  the  Trust,  its  Series  or  the  Variable
     Contracts,  or mutual funds or variable contracts in general, to registered
     representatives of broker-dealers.

o    Providing assistance to broker-dealers that are conducting due diligence on
     the Trust or its Series or the Variable Contracts.

o    Payment of marketing  fees or allowances  requested by  broker-dealers  who
     sell Variable Contracts.

o    Obtaining  information  and  providing  explanations  to Variable  Contract
     owners  regarding  Series   investment   options  and  policies  and  other
     information  about the Trust and its Series,  including the  performance of
     the Series.

o    Training sales personnel regarding sales of Variable Contracts.

o    Personal  service  and/or   maintenance  of  the  Variable  Contract  owner
     accounts.

o    Financing  any other  activity  that is  intended  to result in the sale of
     Trust shares or the Variable Contracts.

The Plan  permits the  Brokerage  Payments and Credits  generated by  securities
transactions  from one  series  of the  Trust to inure to the  benefit  of other
Series as well. The Plan is not expected to increase the brokerage  costs of the
Trust.  For  more  information  about  the  Plan,  please  read  the  "Brokerage
Enhancement Plan" section of the Statement of Additional Information.

              SUPPLEMENT TO THE PROSPECTUS DATED DECEMBER 18, 2000

                  PERSPECTIVE FIXED AND VARIABLE ANNUITY(R)(NY)

                               JNL(R) SERIES TRUST

The prospectus is also being amended by inserting the following new paragraph at
the end of the section of the prospectus entitled "Sub-Advisory Arrangements":

The  Investment  Adviser  and the Trust has  filed an  application  to obtain an
exemption  from the  Securities  and  Exchange  Commission  for a  multi-manager
structure  that  allows the  Investment  Adviser to hire,  replace or  terminate
sub-advisers  without the approval of  shareholders.  The order would also allow
the Investment  Adviser to revise a sub-advisory  agreement with the approval of
the Board of Trustees, but without shareholder approval. If a new sub-adviser is
hired, shareholders will receive information about the new sub-adviser within 90
days of the change. The order would allow the Series to operate more efficiently
and with greater  flexibility.  The  Investment  Adviser  provides the following
oversight and evaluation services to the Series:

o    performing initial due diligence on prospective sub-advisers for the Series

o    monitoring the performance of sub-advisers

o    communicating performance expectations to the sub-advisers

o    ultimately  recommending  to the Board of Trustees  whether a sub-adviser's
     contract should be renewed, modified or terminated.

The  Investment  Adviser  does not  expect  to  recommend  frequent  changes  of
sub-advisers.  Although the Investment  Adviser will monitor the  performance of
the  sub-advisers,  there is no certainty  that any  sub-adviser  or Series will
obtain  favorable  results at any given time.  At a  shareholder  meeting of the
Trust  held  on  October  26,  2000,  all  Series  approved  this  multi-manager
structure.

Certain series of the JNL Series Trust (the "Trust") have adopted a Distribution
Plan under Rule 12b-1 of the  Investment  Company Act of 1940,  as amended  (the
"1940 Act").  Accordingly,  the Prospectus is amended by inserting the following
section after the paragraph  entitled  "Administrative  Fee" which is located in
the "Management of the Trust " section of the prospectus:

                           BROKERAGE ENHANCEMENT PLAN

At a  shareholder  meeting  of the Trust held on October  26,  2000,  all series
except the PPM  America/JNL  Money Market Series and each of the JNL/S&P  Series
adopted,  in accordance  with the provisions of Rule 12b-1 under the 1940 Act, a
Brokerage  Enhancement  Plan (the  "Plan").  The Plan uses  available  brokerage
commissions to promote the sale and  distribution  of Trust shares  (through the
sale of variable insurance products funded by the Trust).


The Plan  authorizes  the  Trust to place  orders  for the  purchase  or sale of
portfolio  securities or other assets with: (i) broker-dealers  that have agreed
to  direct a portion  of their  brokerage  commissions  to  introducing  brokers
("Brokerage  Payments")  to be used to  finance  activities  that are  primarily
intended  to result in the sale of Trust  shares  through  the sale of  Variable
Contracts;  and (ii)  broker-dealers  that,  in addition to executing the trade,
will provide brokerage credits, benefits or other services ("Brokerage Credits")
to be used directly or indirectly  to promote the  distribution  of Trust shares
through the sale of Variable  Contracts.  Management  of JNFS has  informed  the
Board of Trustees of the Trust that  brokerage  commission  rates and commission
amounts paid by the various  Series of the Trust are NOT expected to increase as
a result of the  implementation  of the Plan.  As part of the Plan,  JNLD  would
become the principal  underwriter  of the Series of the Trust adopting the Plan,
with responsibility for promoting sales of shares of such Series.

Under the Plan, JNFS or a Sub-Adviser, would, subject to the requirement to seek
best price and execution,  effect brokerage transactions in portfolio securities
through broker-dealers. It is anticipated that activities or services which will
be procured through Brokerage  Payments and Brokerage Credits given to JNLD will
include:

o    Developing,  preparing,  printing,  and  mailing of  advertisements,  sales
     literature and other promotional material describing and/or relating to the
     Trust, the Series, or the Variable Contracts.

o    Printing  and  mailing  of Trust  prospectuses,  statements  of  additional
     information,   any  supplements   thereto  and   shareholder   reports  for
     prospective Variable Contract owners.

o    Holding or participating in seminars and sales meetings designed to promote
     the  distribution  of  shares of the  Trust,  the  Series  or the  Variable
     Contracts,  including  materials intended either for broker-dealer only use
     or for retail use.

o    Providing   information  about  the  Trust,  its  Series  or  the  Variable
     Contracts,  or mutual funds or variable contracts in general, to registered
     representatives of broker-dealers.

o    Providing assistance to broker-dealers that are conducting due diligence on
     the Trust or its Series or the Variable Contracts.

o    Payment of marketing  fees or allowances  requested by  broker-dealers  who
     sell Variable Contracts.

o    Obtaining  information  and  providing  explanations  to Variable  Contract
     owners  regarding  Series   investment   options  and  policies  and  other
     information  about the Trust and its Series,  including the  performance of
     the Series.

o    Training sales personnel regarding sales of Variable Contracts.

o    Personal  service  and/or   maintenance  of  the  Variable  Contract  owner
     accounts.

o    Financing  any other  activity  that is  intended  to result in the sale of
     Trust shares or the Variable Contracts.

The Plan  permits the  Brokerage  Payments and Credits  generated by  securities
transactions  from one  series  of the  Trust to inure to the  benefit  of other
Series as well. The Plan is not expected to increase the brokerage  costs of the
Trust.  For  more  information  about  the  Plan,  please  read  the  "Brokerage
Enhancement Plan" section of the Statement of Additional Information.
