                                 PROXY STATEMENT

                                     FOR THE
          SPECIAL MEETING OF SHAREHOLDERS TO BE HELD ON JUNE 30, 1998

  This Proxy Statement is furnished to you in connection  with the  solicitation
of Proxies by the Board of Directors of Seligman  Portfolios,  Inc. (the "Fund")
to be used  at the  Special  Meeting  of  Shareholders  (the  "Meeting")  of the
above-named  Portfolios  to be held at the Grand  Hyatt  Hotel,  42nd Street and
Lexington Avenue, New York, New York on June 30, 1998.

  The Fund offers fourteen separate portfolios, each of which is a separate pool
of assets  constituting,  in  effect,  a separate  fund with its own  investment
objectives  and policies.  This Proxy  Statement,  however,  relates to only the
following  four  portfolios:  Seligman  Henderson  International  Portfolio (the
"International  Portfolio"),  Seligman  Henderson  Global  Growth  Opportunities
Portfolio  (the "Global Growth  Opportunities  Portfolio"),  Seligman  Henderson
Global Smaller Companies  Portfolio (the "Global Smaller Companies  Portfolio"),
and Seligman  Henderson  Global  Technology  Portfolio  (the "Global  Technology
Portfolio"). These four portfolios are referred to herein as "Portfolios."

  This Proxy Statement relates to two proposals: (i) the approval of new
Subadvisory Agreements for each Portfolio between J. & W. Seligman & Co. In-
corporated (the "Manager") and Seligman Henderson Co. and (ii) the approval of
a new Subadvisory Agreement with respect to each Portfolio between the Manager
and Henderson Investment Management Limited. Proposals 1 and 2 will be voted
upon separately with respect to each Portfolio by the shareholders of such
Portfolio.

  If the accompanying  form of Proxy is executed  properly and returned,  shares
represented by it will be voted at the Meeting.  If you give  instructions,  the
shares over which you  exercise  voting power will be voted in  accordance  with
your instructions. If you give no instructions and return 

<PAGE>

your  signed  Proxy,  your  shares  will be voted  (i) for the  approval  of new
Subadvisory  Agreements  for each  Portfolio  between the  Manager and  Seligman
Henderson  Co. and (ii) for the  approval of a new  Subadvisory  Agreement  with
respect  to  each  Portfolio  between  the  Manager  and  Henderson   Investment
Management  Limited (which  arrangements will involve no change in the aggregate
fees payable by any Portfolio)  and, at the discretion of the Proxy holders,  on
any  other  matter  that may  properly  have  come  before  the  Meeting  or any
adjournment thereof. You may revoke your Proxy or change it by written notice to
the Fund  (Attention:  the  Secretary)  or by notice at the  Meeting at any time
prior to the time it is voted.

  The close of  business on April 30, 1998 has been fixed as the record date for
the  determination  of  shareholders  entitled to notice of, and to vote at, the
Meeting or any adjournment thereof. On that date, each Portfolio had outstanding
and entitled to vote the number of shares of capital stock set forth below:

<TABLE>

PORTFOLIOS                                                              SHARES
- ---------------------------------------------------------------------- ---------
<S>                                                                    <C>

Seligman Henderson Global Growth Opportunities Portfolio..............   563,512
Seligman Henderson Global Smaller Companies Portfolio................. 1,558,148
Seligman Henderson Global Technology Portfolio........................   385,621
</TABLE>

  Each share of a Portfolio  outstanding  on the record date will be entitled to
one vote at the  Meeting.  For all  matters on which a vote of a majority of the
shares  outstanding  and  entitled to vote is required  (proposals  1 and 2), an
abstention will have the same effect as a vote against the proposal. Abstentions
will be counted for purposes of determining whether a quorum is represented and,
with respect to Proposals 1 and 2, whether a "majority of the outstanding voting
securities" of each Portfolio is represented at the Meeting.

  In the event that a quorum is not  represented  at the  Meeting  or, even if a
quorum is so  represented,  in the event that  sufficient  votes in favor of any
management  proposal  are not received by June 30,  1998,  the persons  named as
proxies may propose  and vote for one or more  adjournments  of the Meeting if a
quorum is not represented  or, if a quorum is so represented,  only with respect
to such  management  proposal,  with no notice other than an announcement at the
Meeting,  and further  solicitation may be made.  Shares  represented by proxies
indicating  a  vote  against  a  management   proposal  will  be  voted  against
adjournment in respect of that proposal.

  Except for shares issued to affiliates of J. & W. Seligman & Co.
Incorporated (the "Manager"), the shareholders of the Portfolios are Canada
Life of America Variable Annuity Account 2 ("CLAVA 2"), Canada Life of America
Annuity Account 2 ("CLAAA 2"), Canada

                                       2
<PAGE>

Life of  America  Annuity  Account 3  ("CLAAA  3") and  Canada  Life of New York
Variable  Annuity Account 2 ("CLNYVA 2"), each of which is a separate account of
either Canada Life Insurance Company of America or Canada Life Insurance Company
of New York.

  CLAVA 2 and CLNYVA 2 are each separate  accounts  that fund  variable  annuity
contracts which invest in the Fund and, in accordance  with current  policies of
the Securities and Exchange Commission, voting power over the Fund's shares with
respect to such  contracts  will be  exercisable by the owners of such contracts
(the  "Contract  Owners").  The  number  of  shares  of  each  Portfolio  that a
particular  Contract Owner will be entitled to vote will generally be determined
by  dividing  the value of his  interest  in each  sub-account  of the  specific
contract by the net asset value per share of the appropriate Portfolio.

  CLAAA 2 and CLAAA 3 are each unregistered  separate accounts that fund pension
plan contracts.  Each separate  account invests in the Fund. The trustees of the
individual  pension plans (the "Plan  Trustees")  have the authority to vote the
shares held in their respective plans.

  Fund shares held by an account for which no voting  instructions  are received
will be voted on each  matter  in the same  proportion  as such  shares  in that
sub-account for which voting instructions are received.

  The Fund is managed by the Manager.  Seligman Henderson Co. (the "Subadviser")
supervises and directs the non-U.S.  investments of the  Portfolios.  The Fund's
distributor  (principal  underwriter) is Seligman Financial  Services,  Inc. The
address of each of these entities is 100 Park Avenue,  New York, New York 10017.
The address of Canada  Life  Insurance  Company of America is 6201 Powers  Ferry
Road,  NW,  Atlanta,  GA 30339  ((800)  333-2542).  The  address of Canada  Life
Insurance  Company of New York is 500  Mamaroneck  Avenue,  Harri- son, NY 10528
((914)  835-8400).  The Fund will furnish,  without  charge,  copies of its most
recent annual report and semi-annual  report to any shareholder  upon request to
the Fund at (800) 221-7844.

  It is expected that the Notice of Special Meeting, Proxy Statement and form of
Proxy will first be mailed to shareholders on or about May 18, 1998.

                  A. APPROVAL OF NEW SUBADVISORY ARRANGEMENTS

                 (Proposal 1--Interim Subadvisory Agreements)
                 (Proposal 2--Proposed Subadvisory Agreement)

GENERAL

  Original Subadvisory Agreements. Pursuant to Management Agreements between the
Manager  and  the  Fund,  on  behalf  of its  several  Portfolios,  the  Manager
administers the business and other affairs of the Fund.  Seligman  Henderson Co.
serves as  Subadviser  to the  Portfolios  pursuant  to  subadvisory  agreements
between the Manager and the  Subadviser,  which provide that the Subadviser will
supervise and direct the Portfolios'  global investments in accordance with each
Portfolio's investment objective, policies and restrictions. As explained below,
the  original  subadvisory  agreements  for each  Portfolio  (collectively,  the
"Original Subadvisory  Agreements") terminated in accordance with their terms on
March 30, 1998, and the Manager and the Subadviser  entered into new subadvisory
agreements  that are  identical to the Original  Subadvisory  Agreements  in all
respects  except  as  to  their   commencement   dates  and  termination   dates
(collectively,  the "Interim Subadvisory  Agreements").  Fees under the Original
Subadvisory  Agreements  were  paid,  and fees  under  the  Interim  Subadvisory
Agreements are paid,  directly by the Manager from its management fee and do not
affect the fees paid by the Portfolios of the Fund.

  The  Subadviser  was  founded  in 1991 as a general  partnership  between  the
Manager  and  Henderson  International,  Inc.,  each  partner  owning  equal 50%
interests in the joint venture.  Henderson International,  Inc., whose principal
address  is 3 Finsbury  Avenue,  London  EC2M 2PA,  England,  is a wholly  owned
subsidiary of Henderson plc, a United Kingdom corporation  ("Henderson") located
at the same address. The Subadviser is headquartered in New York and was created
to  provide   international  and  global  investment   management   services  to
institutional  and individual  investors and investment  companies in the United
States.

  The Subadviser  currently  serves as subadviser  for investment  portfolios of
another investment company managed by the Manager. A table setting forth the net
assets of those investment  companies for which the Subadviser  currently serves
as  subadviser,  and which have  investment  objectives  similar to those of the
indicated  Portfolios of the Fund,  and the  subadvisory  fee rates paid by such
companies,  is attached as Exhibit C to this Proxy Statement.  The aggregate net
assets managed by the Subadviser  were  approximately  $3.6 billion at March 31,
1998, including $45.8 million of the Fund's net assets.

  The Original Subadvisory Agreement relating to the International Portfolio was
dated May 1, 1993;  the Original  Subadvisory  Agreement  relating to the Global
Smaller  Companies  Portfolio  was  dated  October  1,  1994;  and the  Original
Subadvisory Agreement relating to the Global Growth

                                       4
<PAGE>

Opportunities  Portfolio  and the Global  Technology  Portfolio was dated May 1,
1996.  The Board of  Directors of the Fund  approved  the  Original  Subadvisory
Agreement relating to the International Portfolio on March 18, 1993; relating to
the Global  Smaller  Companies  Portfolio on July 21, 1994;  and relating to the
Global Growth  Opportunities  Portfolio and the Global  Technology  Portfolio on
March 21, 1996.  The  Original  Subadvisory  Agreement  was approved by the sole
shareholder  of the  International  Portfolio  on April  30,  1993;  by the sole
shareholder  of Global  Smaller  Companies  Portfolio on October 3, 1994; by the
sole shareholder of the Global Growth Opportunities Portfolio on April 26, 1996;
and by the sole  shareholder  of the Global  Technology  Portfolio  on April 26,
1996. The Original  Subadvisory  Agreements  were not submitted to a vote of the
shareholders  of the Fund  subsequent to their  initial  approvals in respect of
each Portfolio.

  The AMP  Transaction.  On February  3, 1998,  the boards of  directors  of AMP
Limited ("AMP"),  an Australian life insurance and financial  services  company,
and  Henderson  announced  that  they had  reached  agreement  on the terms of a
recommended  cash  offer  by a  subsidiary  of AMP for all of the  issued  share
capital of Henderson.  The  acquisition of Henderson by AMP (the  "Acquisition")
was completed on March 30, 1998.  Under the Investment  Company Act of 1940 (the
"1940 Act"), AMP is deemed to "control"  Henderson because it owns more than 25%
of Henderson's outstanding voting securities.

  The  Acquisition  may be deemed to have resulted in a change of control of the
Subadviser,  because a wholly  owned  subsidiary  of Henderson is one of the two
general partners of the Subadviser. Such a change of control would constitute an
"assignment,"  and thus the termination in accordance with its terms, of each of
the  Original  Subadvisory  Agreements.   March  30,  1998,  the  date  of  such
assignment, is referred to herein as the "Assignment Date."

  Interim Subadvisory  Agreements.  On March 19, 1998, the Board of Directors of
the Fund unanimously approved the Interim Subadvisory Agreements,  each of which
is identical to the corresponding  Original  Subadvisory  Agreement except as to
its commencement date and its termination date, and recommended approval of such
Agreements by the shareholders of each Portfolio.  The factors considered by the
Board of Directors in approving the Interim Subadvisory Agreements are described
below  under  "Factors  Considered  by the  Board  of  Directors."  The  Interim
Subadvisory  Agreements took effect (subject to approval by the shareholders) on
the Assignment Date and will continue in effect until the Restructuring Date (as
defined  below)  (subject to approval by the  shareholders  of Proposal  2). The
period from the Assignment Date to the Restructuring  Date is referred to as the
"Interim  Period." The Special  Meeting is being called,  in part, in order that
you have the opportunity to vote on the Interim Subadvisory  Agreements.  If the
shareholders do

                                       5
<PAGE>

not approve the Interim Subadvisory Agreement applicable to any Portfolio of the
Fund, the Manager will assume responsibility for the management of the assets of
that Portfolio during the remainder of the Interim Period for such Portfolio, if
any.

  AMP,  Henderson and the Subadviser  have obtained an order from the Securities
and Exchange Commission (the "Order")  permitting the  implementation,  prior to
obtaining shareholder  approval,  of each of the Interim Subadvisory  Agreements
for a period  of not more than 150 days  beginning  on the  Assignment  Date and
continuing  through  the date on which such  Interim  Subadvisory  Agreement  is
approved or disapproved by the applicable  Portfolio's  shareholders,  but in no
event after  October 1, 1998.  Such 150-day  period will end on August 22, 1998.
The Interim  Period is expected  to fall within the period  contemplated  by the
Order.  The Order  permits the  Subadviser  to receive all fees earned under the
Interim  Subadvisory  Agreements  during the Interim Period,  provided that such
fees  are  paid  into  an  interest-bearing  escrow  account  maintained  by  an
unaffiliated  escrow  agent.  The Manager and the  Subadviser  have entered into
escrow  agreements with United States Trust Company of New York, as escrow agent
(the "Escrow Agent") for this purpose.  The escrow arrangements were approved by
the Board of Directors at their meeting on March 19, 1998. The Escrow Agent will
pay the amounts in the escrow  account  (including  interest)  in respect of any
Portfolio  of the Fund to the  Subadviser  only  after the  Interim  Subadvisory
Agreement  applicable to such Portfolio is approved by the  shareholders of that
Portfolio.  If the  shareholders  of a  Portfolio  do not  approve  the  Interim
Subadvisory  Agreement,  the amounts held in escrow in respect of such Agreement
will be returned to the Portfolio.

  A copy of each Interim Subadvisory Agreement is set forth as Exhibit A to this
Proxy Statement.

  Proposed Subadvisory  Agreement.  As a result of the AMP transaction and other
developments in the asset management  businesses conducted by the Manager and by
Henderson,  the Manager  and  Henderson  have  proposed a  restructuring  of the
existing subadvisory  arrangements for each Portfolio of the Fund. Henderson and
the  Manager  have  proposed   that,   for  each  Portfolio  of  the  Fund,  all
responsibilities in respect of such Portfolio's  international  investments that
are currently  undertaken by the Subadviser  pursuant to the Interim Subadvisory
Agreements  be assumed by  Henderson  Investment  Management  Limited  (the "New
Subadviser"),  a wholly  owned  subsidiary  of  Henderson  that has  applied for
registration as an investment adviser under the Investment Advisers Act of 1940,
pursuant  to a  new  subadvisory  agreement  relating  to  all  Portfolios  (the
"Proposed Subadvisory Agreement").  On April 30, 1998, the Directors of the Fund
unanimously  approved  the  Proposed  Subadvisory  Agreement  in respect of each
Portfolio and recommended that the shareholders approve it. A description of the
terms of the Proposed Subadvisory  Agreement,  and the factors considered by the
Directors in approving it, is set forth below. The Proposed

                                       6
<PAGE>

Subadvisory Agreement provides for a different structure for fees payable by the
Manager  to the New  Subadviser,  but it would not  result in any  change in the
aggregate fees payable by any Portfolio.  If the Proposed Subadvisory  Agreement
is approved in respect of a Portfolio,  it will take effect with respect to that
Portfolio  on  the  day  after  the  date  of  approval  by the  Portfolio  (the
"Restructuring  Date") and the Interim Subadvisory  Agreement in respect of such
Portfolio will terminate on the Restructuring Date. Since the Special Meeting of
Shareholders  is to be held on June 30, 1998,  the  Restructuring  Date for each
Portfolio is expected to be July 1, 1998,  subject to the  effectiveness  of the
New Subadviser's registration as an investment adviser.

  A copy of the Proposed Subadvisory Agreement is set forth as Exhibit B to this
Proxy Statement.

TERMS OF THE ORIGINAL SUBADVISORY AGREEMENTS

  Under each Original Subadvisory Agreement, the Subadviser,  at its expense and
subject to the  control of the Board of  Directors  and in  accordance  with the
objectives,  policies and  principles of the relevant  Portfolio of the Fund set
forth  in  the  Fund's  Prospectus,   provided  the  Portfolio  with  investment
management services,  including investment research, advice and supervision. The
Original Subadvisory Agreements related to all assets of a Portfolio,  including
investments  in securities of U.S. as well as foreign  issuers.  The  Subadviser
determined which securities were to be purchased or sold by the Portfolio,  made
purchases and sales of securities on behalf of the Portfolio and  determined how
any rights of the Portfolio were to be exercised. The Subadviser did not perform
any non-advisory services under the Original Subadvisory Agreements.

  The  Original  Subadvisory  Agreements  provided  that they would  continue in
effect  from  year to  year if such  continuance  were  approved  in the  manner
required by the 1940 Act, and if the  Subadviser had not notified the Manager at
least  60  days  prior  to an  anniversary  date  that it did  not  desire  such
continuance.  The Original  Subadvisory  Agreements were terminable by the Fund,
without  penalty,  on 60 days' written notice to the Subadviser and provided for
automatic  termination in the event of their  assignment or upon  termination of
the Management Agreement.

  The Original  Subadvisory  Agreement relating to each Portfolio provided for a
fee in respect of each such Portfolio,  calculated daily and paid monthly, equal
to 0.90 percent per annum of the average daily net assets of that Portfolio. The
Management  Agreement  provides  for a fee in respect of each  Portfolio  of the
Fund, calculated daily and paid monthly,  equal to 1.00 percent per annum of the
average daily net assets of that Portfolio.  The aggregate subadvisory fees paid
by the Manager to the Subadviser pursuant to the Original Subadvisory Agreements
during the year ended Decem-

                                       7
<PAGE>

ber 31, 1997 in respect of each Portfolio were as follows: International Port-
folio: $28,721; Global Growth Opportunities Portfolio: $11,265; Global Smaller
Companies Portfolio: $168,952; and Global Technology Portfolio: $7,951.

TERMS OF THE INTERIM SUBADVISORY AGREEMENTS

  Each  Interim  Subadvisory  Agreement  is  identical  in all  respects  to the
Original  Subadvisory  Agreement  for the  corresponding  Portfolio  of the Fund
except as to its commencement date and termination date. The Interim Subadvisory
Agreements commenced on the Assignment Date and provide by their terms that they
will continue in effect until  December 31, 1998,  and  thereafter  from year to
year if such continuance is specifically  approved in the manner required by the
1940 Act, and if the Subadviser  shall not have notified the Manager at least 60
days prior to an anniversary date that it does not desire such continuance.  (As
discussed above,  however, if the Proposed Subadvisory  Agreement is approved by
shareholders,  it is contemplated that the Interim  Subadvisory  Agreements will
terminate on the Restructuring Date.)

TERMS OF THE PROPOSED SUBADVISORY AGREEMENT

  Under the  Proposed  Subadvisory  Agreement,  the New  Subadviser,  which is a
wholly owned subsidiary of Henderson,  would agree to furnish to the Manager and
the Fund such investment  advice,  research and assistance as the Manager or the
Fund from time to time reasonably  requests with respect to the Portfolios.  The
New  Subadviser's  responsibilities  would  include  (1)  participating  in  the
development  of  each  Portfolio's   overall  investment  strategy  and  in  the
determination  of country  allocations and sector and industry  weightings;  (2)
providing  investment  advice and  research  with  respect  to each  Portfolio's
existing and potential investments in securities of non-U.S. issuers,  including
company  visits and meetings with  management;  (3)  determining  securities for
investment;  (4)  selecting  brokers;  and (5) causing the  execution of trades,
including foreign exchange dealings.  The Proposed  Subadvisory  Agreement would
also require the New Subadviser to make available  representatives  to report to
the Board of  Directors of the Fund in person on at least a  semi-annual  basis,
and to provide  such reports and other  information  as the Manager or the Board
may reasonably request.

  Under the Proposed  Subadvisory  Agreement,  the New Subadviser  will not have
ultimate  responsibility  for portfolio  accounting and pricing  (although it is
specifically  required to assist in the pricing of assets under its  supervision
which cannot be readily priced),  as such services are generally provided by the
Fund's  recordkeeping agent under the supervision of the Manager.  However,  the
New Subadviser would be responsible for  co-ordinating  custody matters with the
Fund's  custodians in respect of the Fund's assets under the  supervision of the
New Subadviser.  The Management Agreement with respect to the Fund provides that
the Manager continues to have responsibility for

                                       8
<PAGE>

investment  management  services  provided by any subadviser to the Fund and, in
particular,  that  in the  event  a  subadviser  ceases  to  provide  any of the
investment  management  services  identified in the Management  Agreement,  such
services  must be provided  by the Manager or by some other form of  arrangement
approved by the Fund.  Accordingly,  the  Manager  will be  responsible  for any
investment  management  services that it does not request the New  Subadviser to
provide  under the  Proposed  Subadvisory  Agreement,  including  services  with
respect  to the U.S.  assets  of the Fund  that are  currently  provided  by the
Subadviser.

  The form of the  Proposed  Subadvisory  Agreement,  which  would  replace  the
Interim  Subadvisory  Agreements,  is set  forth  as  Exhibit  B to  this  Proxy
Statement.

  The Proposed  Subadvisory  Agreement  provides that it will continue in effect
with respect to each Portfolio of the Fund until December 31, 1999 and from year
to year thereafter if such continuance is approved in the manner required by the
1940 Act,  and if the New  Subadviser  has not  notified the Manager at least 60
days prior to an anniversary  date that it does not desire such continuance with
respect to any Portfolio.  The Proposed  Subadvisory  Agreement is terminable by
the Fund with respect to any  Portfolio,  without  penalty,  on 60 days' written
notice to the New Subadviser and will  terminate  automatically  in the event of
its assignment or upon termination of the Management Agreement.

  The Proposed  Subadvisory  Agreement  would apply on a  Portfolio-by-Portfolio
basis,  and the New  Subadviser's  fee for each Portfolio would be calculated on
the basis of the assets of such Portfolio.  The Proposed  Subadvisory  Agreement
provides  that the Manager  will pay to the New  Subadviser  for its  services a
monthly fee calculated at an annual rate of 0.50% of the average  monthly assets
under  the  New  Subadviser's  supervision.   Average  monthly  assets  will  be
determined  for any month by taking the average of the assets  (adjusted  to add
receivables for assets sold and deduct payables for assets  purchased) under the
New Subadviser's  supervision as of (i) the opening of business on the first day
of such month and (ii) the close of business on the last day of such month.  The
subadvisory  fee is payable by the Manager from its own management  fee, and the
change in the  subadvisory  fee rate  contemplated  by the Proposed  Subadvisory
Agreement will have no effect on the fees payable by any Portfolio of the Fund.

SUMMARY OF PRINCIPAL DIFFERENCES BETWEEN AGREEMENTS

  The principal differences between the Original Subadvisory  Agreements and the
Interim Subadvisory  Agreements,  on the one hand, and the Proposed  Subadvisory
Agreement,  on the other,  are the  substitution  of the New  Subadviser for the
Subadviser, the revised fee structure and the allocation of responsibilities and
scope  of  services  to be  provided.  In  addition,  the  Proposed  Subadvisory
Agreement provides that the New Subadviser shall be subject to a higher standard
of care  (negligence) as compared with the Original  Subadvisory  Agreements and
the Interim

                                       9
<PAGE>

Subadvisory Agreements (gross negligence). As discussed above, the Subadviser is
a  50-50  joint  venture  between  the  Manager  and  Henderson,  while  the New
Subadviser is a wholly owned subsidiary of Henderson.  The Subadviser  comprises
personnel  from both the Manager and Henderson  and provides  advice on a global
basis,  whereas the personnel of the New  Subadviser  will be drawn  exclusively
from  Henderson  and will provide  advice  principally  with respect to non-U.S.
investments,  with the  Manager  assuming  responsibility  for the  Fund's  U.S.
investments.  The change in ownership structure also means that the Manager will
have no share in the profits or losses of the New Subadviser.

  The  Subadviser  currently  receives  a fee  equal to 0.90%  per  annum of the
average  daily net  assets of each  Portfolio.  Under the  Proposed  Subadvisory
Agreement,  the New Subadviser would receive 0.50% of the average monthly assets
of each  Portfolio  under its  supervision.  Because the ownership  structure is
different,  the  fee  rates  are  different,  and  the fee  under  the  Proposed
Subadvisory  Agreement  would be  calculated  on the basis of  assets  under the
Subadviser's  supervision  (which will be non-U.S.  assets)  rather than all net
assets of a Portfolio,  the fees that will be earned by the New  Subadviser  are
not directly  comparable  with those earned by the Subadviser  under the current
arrangements.   The   Portfolios  of  the  Fund  invest  in  foreign  assets  to
significantly different degrees. As a practical matter,  International Portfolio
invests solely in foreign assets; Global Growth Opportunities  Portfolio invests
principally in foreign assets; and Global Smaller Companies Portfolio and Global
Technology  Portfolio tend to invest  approximately  equally in U.S. and foreign
assets. The split between U.S. and non-U.S. assets in the Portfolios that invest
in both types of assets  fluctuates  over time.  Such split is determined by the
Subadviser under the Interim Subadvisory Agreements,  and would be determined by
the  Manager  under  the  Proposed  Subadvisory   Agreement.   In  addition,  in
considering whether to vote in favor of the Proposed Subadvisory  Agreement,  it
is important to remember that the subadvisory fee is payable by the Manager from
its own management fee, and approval of the Proposed Subadvisory  Agreement will
have no effect on the fees payable by any Portfolio of the Fund.

  The Proposed  Subadvisory  Agreement  provides that the New  Subadvisor  would
provide the  Manager  and the Fund with such  investment  advice,  research  and
assistance as the Manager or the Fund shall from time to time reasonably request
with respect to the Portfolios.  This differs from the arrangements provided for
under  the  Original   Subadvisory   Agreements  and  the  Interim   Subadvisory
Agreements,  reflecting the greater role of the Manager.  The proposed fee to be
paid to the New Subadviser under the Proposed Subadvisory Agreement also differs
from  the fee  paid  under  the  Original  Subadvisory  Agreements  and  Interim
Subadvisory  Agreements,  which contemplate that the Subadviser will provide all
investment advisory services required by the Fund, as described in the preceding
paragraph.

  If the Proposed Subadvisory Agreement is approved by shareholders, the Manager
and the New Subadviser intend to enter into a separate  agreement that provides,
among other things,  for the payment by the Manager of specified  amounts to the
New  Subadviser  in  the  event  that  the  Proposed  Subadvisory  Agreement  is
terminated.  Under  such  agreement,  if the  Manager  terminates  the  Proposed
Subadvisory  Agreement  prior  to June 30,  2001  (other  than as a result  of a
material breach by the New Subadviser of its obligations thereunder or a request
by the New  Subadviser to terminate  the Proposed  Subadvisory  Agreement),  the
Manager will make payments to the New Subadviser in respect of each Portfolio as
to which the New  Subadvisory  Agreement is cancelled in the following  amounts:
International Portfolio:  $24,000; Global Smaller Companies Portfolio:  $27,000;
Global Technology  Portfolio:  $5,000;  Global Growth  Opportunities  Portfolio:
$11,000.  Additionally,  if such termination  occurs prior to December 31, 1999,
the Manager will also pay to the New Subadviser an amount equal to the fees that
the New Subadviser  would have earned under the Proposed  Subadvisory  Agreement
from the date of  termination  through  December  31,  1999,  calculated  on the
assumption  that the Fund's assets under the New  Subadviser's  supervision  are
equal  throughout such period to their value on the date of  termination.  These
payments  would be made by the  Manager  from its own  resources  and not by any
Portfolio of the Fund or its shareholders. The agreement between the Manager and
the New  Subadviser  also  provides  that the Manager may change the name of the
Portfolios and that Henderson has the right to remove its name from the names of
the  Portfolios.  Any name change of any Portfolio  would require  action by the
Board of Directors.

FACTORS CONSIDERED BY THE BOARD OF DIRECTORS

  Interim Subadvisory Agreements.  The Directors of the Fund met on February 12,
March 5, and March 19, 1998 to evaluate the  transaction  between  Henderson and
AMP and its expected  effect on the  Subadviser  and the services the Subadviser
provides  to each  Portfolio  of the  Fund.  At  these  meetings,  the  Board of
Directors  considered  various  matters in  determining  to approve  the Interim
Subadvisory   Agreements  and  recommend  them  to  the   shareholders.   Senior
representatives of AMP,  Henderson,  the Manager and the Subadviser provided the
Directors with detailed information about the expected effect of the Acquisition
on the  Subadviser.  The Fund's legal counsel  advised the Board of Directors on
the nature of the matters to be  considered  and the standards to be used by the
Board of Directors in reaching its decision.

  The Directors had  evaluated the Original  Subadvisory  Agreements in November
1997 in connection with their annual  determination as to their continuance,  as
required by the 1940 Act.  The factors  that were  considered  in November  1997
included  principles  established  by  judicial  decisions;  the  amount  of the
subadvisory  fees paid by the Portfolios of the Fund;  the services  provided by
the  Subadviser,  its past  performance  and the quality of its  personnel;  the
portfolio transaction allocation

                                      11
<PAGE>

policies followed;  portfolio turnover  information;  the non-advisory  services
provided  to the  Fund;  the  expenses  borne by the  Fund  and the  Subadviser;
comparisons  with  other  funds;  the  profitability  of  the  contracts  to the
Subadviser;   the  standards  of  care  required  by  the  Original  Subadvisory
Agreements;  the services offered and fees charged by other investment  advisers
and  subadvisers;  and the  financial  stability  of the  Subadviser.  In  their
evaluation of the Interim Subadvisory Agreements in February and March 1998, the
Directors  reviewed these  considerations in light of the proposed  Acquisition,
drawing on their knowledge of the operations and competence of Henderson and the
Subadviser  gained as a result of serving as Directors  of the other  investment
companies in the Seligman Group.

  The Directors  also  specifically  considered  the  anticipated  impact of the
Acquisition  on each  Portfolio  of the Fund and other  factors  related  to the
Acquisition, including:

  .  The effect on the Subadviser's provision of investment subadvisory serv-
     ices, including such matters as any plans for changes in investment ad-
     visory personnel and the levels of research and technical support avail-
     able to such persons, and the impact of the planned combination of the
     asset management businesses of AMP and Henderson. In this regard, the
     Directors considered the possible beneficial effect of the significantly
     enhanced financial resources of Henderson after the Acquisition and the
     fact that the combined entity would have more assets under management
     than Henderson alone before the Acquisition. The Directors also consid-
     ered information concerning AMP and AMP's current asset management busi-
     ness, as well as AMP's plans for the future. Representatives of AMP and
     Henderson advised the Directors that the Acquisition would not result in
     any reduction in the quality of services now provided to the Fund and
     that they did not expect the change in control of Henderson to result in
     any material changes in the manner in which the Subadviser renders serv-
     ices to the Fund. The AMP and Henderson representatives also stated that
     neither the Acquisition nor any ancillary transactions would have any
     adverse effect on the Subadviser's ability to fulfill its obligations
     under the Interim Subadvisory Agreements or to operate its business in a
     manner consistent with past business practice.

  .  The effects of the  Acquisition  on the  Manager's  relationship  with Hen-
     derson  and  the  Subadviser   over  the  near  and  longer  term  and  the
     implications for the Subadviser's  capabilities and relationships  with the
     Fund.

  .  The arrangements  pursuant to which the current  professionals and managers
     of Henderson  that are  involved  with the  Subadviser  would be induced to
     remain with the new organization and the effects of the Acquisition on such
     persons and the other officers and employees of Henderson that are involved
     with the Subadviser.


                                      12

  .  The  nature,  extent  and  quality  of the  management  and  administrative
     services  currently  provided  by the  Subadviser,  the  Manager  and other
     service  providers  to the Fund and the  expected  impact,  if any,  of the
     Acquisition on such services.

  .  The  current and  prospective  financial  condition  and  stability  of the
     combined AMP/Henderson asset management entity after the Acquisition.

  .  Any  advantages or  disadvantages  to the Fund or any of its  Portfolios in
     remaining one of the  investment  companies  subadvised  by the  Subadviser
     (giving effect to the changes that might result from the Acquisition).

  .  The fact that  Henderson and the Manager agreed to bear the Fund's costs of
     obtaining  director  and  shareholder  approval of the Interim  Subadvisory
     Agreements.

  .  The  possible  impact  of  the  Acquisition  on the  information  regularly
     provided to the Directors, including information about the profitability of
     the Fund to the Subadviser.

  .  The Manager's  representation  to the Board that the Acquisition  would not
     create an undue burden on the Fund or its shareholders  under Section 15(f)
     of the 1940 Act.  In  addition,  75 percent of the members of the Board are
     currently not interested persons of the Subadviser.

  .  An  undertaking  by the  Subadviser  to  continue  to  provide  subadvisory
     services  on an  interim  basis in the event  shareholder  approval  of the
     Interim  Subadvisory  Agreements  is not  obtained  within the time  period
     provided by the Order.

  .  Current developments in the investment company and investment advisory
     industries.

  After careful  consideration,  the Directors  unanimously approved the Interim
Subadvisory  Agreements and recommended  that the shareholders of each Portfolio
of the  Fund  approve  the  Interim  Subadvisory  Agreement  applicable  to such
Portfolio.

  Proposed  Subadvisory  Agreement.  The  Directors of the Fund met on April 30,
1998 to  evaluate  the  Proposed  Subadvisory  Agreement  with  respect  to each
Portfolio  of the  Fund.  At this  meeting,  the Board of  Directors  considered
various matters in determining to approve the Proposed Subadvisory Agreement and
recommend it to the  shareholders.  Senior  representatives  of  Henderson,  the
Manager and the New Subadviser provided the Directors with detailed  information
in  connection  with the approval of the  Proposed  Subadvisory  Agreement.  The
Fund's legal counsel advised the Board of Directors on the nature of the matters
to be  considered  and the  standards  to be used by the Board of  Directors  in
reaching its decision.

  In their evaluation of the Proposed  Subadvisory  Agreement on April 30, 1998,
the Directors reviewed  considerations  substantially similar to those set forth
above in  "Factors  Considered  by the Board of  Directors--Interim  Subadvisory
Agreements," as they related to the Proposed

                                      13
<PAGE>

Subadvisory Agreement. In addition, the Directors considered the following ad-
ditional factors specifically relating to the Proposed Subadvisory Agreement:

  .  The  fees  payable  under  the  Proposed  Subadvisory  Agreement,  and  the
     relationship of such fees, among other things, to the services  anticipated
     to be provided by the New Subadviser and the Manager.

  .  The  business  arrangements  between  the  Manager  and the New  Subadviser
     described above and the potential  impact on the Portfolios in the event of
     the removal of the Henderson name from the Portfolios' names.

  .  The proposed allocation of responsibilities and scope of services to be
     provided by the Manager and the New Subadviser.

  .  The fairness and  reasonableness of the subadvisory fees under the Proposed
     Subadvisory   Agreement  and  the  management  fees  under  the  Management
     Agreements, in light of the Proposed Subadvisory Agreement,  including that
     the  portion  of the  management  fees to be  retained  by the  Manager  is
     justified  by  the  level,   nature  and  quality  of  services   provided,
     expectations  of the  Manager's  future  activities,  and  the  anticipated
     profitability to the Manager of the fee allocation.

  The Directors  reviewed the considerations  mentioned above,  drawing on their
knowledge  gained  as a result  of  serving  on the  Board of the Fund and other
investment  companies in the Seligman Group,  with respect to the operations and
competence  of Henderson  generally,  and  particularly,  the  competence of the
investment  management and other personnel of the Subadviser who are expected to
continue  providing  services to the Fund through their affiliation with the New
Subadviser.

  After careful  consideration,  the Directors unanimously approved the Proposed
Subadvisory  Agreement and recommended  that the  shareholders of each Portfolio
approve the Proposed Subadvisory Agreement in respect of such Portfolio.

  The  affirmative  vote of a majority of the outstanding  voting  securities of
each Portfolio is required for the adoption of each of Proposal 1 and Proposal 2
with respect to such Portfolio. Under the 1940 Act, a "vote of a majority of the
outstanding  voting securities" of a Portfolio means the affirmative vote of the
lesser of (1) more than 50% of the  outstanding  shares of the  Portfolio or (2)
67% or more of the shares present at a shareholders' meeting if more than 50% of
the outstanding shares are represented at the meeting in person or by proxy.

  If  Proposal  1 is  approved  by the  shareholders  of each  Portfolio  at the
Meeting,  the  Subadviser's  activities  pursuant  to  the  Interim  Subadvisory
Agreements  since the Assignment Date will be approved and the Escrow Agent will
pay the  amounts  held in the escrow  account  to the  Subadviser.  The  Interim
Subadvisory  Agreements  will  continue in effect until  December 31, 1998,  and
thereafter

                                      14
<PAGE>

from year to year if such  continuance  is  specifically  approved in the manner
required by the 1940 Act,  and if the  Subadviser  shall not have  notified  the
Manager  at least 60 days prior to an  anniversary  date that it does not desire
such continuance,  unless Proposal 2 is also approved by the shareholders at the
Meeting. If Proposal 1 is not approved by the shareholders of any Portfolio, the
Escrow Agent will pay the amounts held in the escrow  account to the  applicable
Portfolio of the Fund.

  If  Proposal  2 is  approved  by the  shareholders  of each  Portfolio  at the
Meeting,  the Interim  Subadvisory  Agreements will continue in effect until the
Restructuring  Date.  On  the  Restructuring  Date,  the  Proposed   Subadvisory
Agreement  will take effect,  and it will continue in effect until  December 31,
1999,  and  thereafter  from year to year if such  continuance  is  specifically
approved in the manner required by the 1940 Act, and if the New Subadviser shall
not have notified the Manager at least 60 days prior to an anniversary date that
it does not desire such continuance with respect to any Portfolio.

  If  Proposal 1 and  Proposal 2 are not  approved  by the  shareholders  of any
Portfolio, the Manager will assume all responsibilities  currently undertaken by
the  Subadviser in respect of such  Portfolio  and the  Directors  will consider
whether any additional action should be taken.

       YOUR         BOARD OF DIRECTORS UNANIMOUSLY  RECOMMENDS THAT SHAREHOLDERS
                    VOTE FOR PROPOSAL 1 AND FOR PROPOSAL 2.

EC2M 2PA, England. The address of Messrs. Schmaltz, Smith, Stein and Zino is
100 Park Avenue, New York, New York 10017.

  William C. Morris owns a majority of the outstanding voting securities of
the Manager. Accordingly, under the applicable provisions of the 1940 Act, Mr.
Morris is a control person of the Manager. Because the Manager owns a 50% in-
terest in the Subadviser, Mr. Morris may also be deemed to own indirectly a
material interest in the Subadviser. Messrs. Richard R. Schmaltz and Brian T.
Zino are also a shareholders of the Manager.

  As of January 1, 1997,  Richard R.  Schmaltz  bought 500 Class A common shares
and 500 Class B common  shares of the Manager from the Manager,  each at a price
of $230.60 per share.  As of January 1, 1998,  Mr.  Schmaltz  bought 500 Class A
common  shares and 1,000 Class B common  shares of the Manager from the Manager,
each at a price of $239.48 per share.

  Additionally, Lawrence P. Vogel, Vice President of the Fund, is Treasurer of
the Subadviser; and Frank J. Nasta, Secretary of the Fund, is Secretary of the
Subadviser.

  During the fiscal year ended  December 31, 1997, no  commissions  were paid by
the Fund to any broker affiliated with the Subadviser.

  The principal executive officer of the New Subadviser is Dugald M. Eadie.
The New Subadviser is governed by a Management Committee comprised of the fol-

                   B. OTHER MATTERS; SHAREHOLDER PROPOSALS.

  The Fund knows of no other matters which are to be brought before the Meeting.
However,  if any other matters come before the Meeting,  it is intended that the
persons named in the enclosed form of Proxy, or their substitutes, will vote the
Proxy in accordance with their judgment on such matters.

  A shareholder  proposal  intended to be represented  at any meeting  hereafter
called  must be  received  by the  Fund  within a  reasonable  time  before  the
solicitation  relating  thereto is made in order to be included in the notice of
meeting,  proxy statement and form of proxy relating to such meeting.  Under the
current By-Laws of the Fund,  meetings of  shareholders  are required to be held
only  when  necessary  under  the  1940  Act.  It  is  therefore  unlikely  that
shareholder  meetings  will be held on an  annual  basis.  The  submission  by a
shareholder  of a  proposal  for  inclusion  in the  proxy  statement  does  not
guarantee that it will be included. Shareholder proposals are subject to certain
regulations under federal law.

addition to the use of the mails,  Proxies  may be  solicited  personally  or by
telephone or facsimile by  Directors,  officers and  employees of the Fund,  the
Manager,  Seligman Financial  Services,  Inc. and Seligman  Services,  Inc., and

reimbursed  for  their  expenses  in  sending  solicitation  material  to  their
principals.

                                           By order of the Board of Directors,

                (with respect to the International Portfolio*)

                              SUBADVISORY AGREEMENT

  SUBADVISORY AGREEMENT, dated as of March 30, 1998 between J. & W. SELIGMAN &
CO. INCORPORATED, a Delaware corporation (the "Manager") and Seligman
Henderson Co., a New York general partnership (the "Subadviser").

  WHEREAS, the Manager has entered into a Management Agreement dated May 1, 1993
(the "Management Agreement") with Seligman Portfolios, Inc. (the "Corporation"),
an open-end  diversified  management  investment  company  registered  under the
Investment  Company Act of 1940,  as amended (the "1940 Act"),  on behalf of the
Seligman  Henderson  Global  Portfolio  of  the  Corporation  (the  "Portfolio")
pursuant to which the Manager  will render or contract to obtain as  hereinafter
provided investment management services to the Portfolio,  and to administer the
business and other affairs of the Portfolio; and

  WHEREAS,  the Manager  desires to retain the Subadviser to provide  investment
management  services to the  Portfolio,  and the Subadviser is willing to render
such investment management services.

  NOW, THEREFORE, in consideration of the mutual covenants contained herein, the
parties hereto agree as follows:

  1. DUTIES OF THE  SUBADVISER.  The Subadviser  will provide the Portfolio with
investment  management  services,  including  investment  research,  advice  and
supervision,  determining  which  securities  shall be  purchased or sold by the
Portfolio,  making  purchases and sales of securities on behalf of the Portfolio
and  determining  how voting and other rights with respect to  securities of the
Portfolio  shall be exercised,  subject in each case to the control of the Board
of Directors of the Corporation and in accordance with the objectives,  policies
and principles set forth in the Registration Statement and Prospectus(es) of the
Corporation and the requirements of the 1940 Act and other applicable law.

  Subject to Section 36 of the 1940 Act, the Subadviser shall not be liable to
the Corporation for any error of judgment or mistake of law or for any loss
arising out of any investment or for any act or omission in the management of
the Corporation and the performance of its duties under this Agreement except
for willful misfeasance, bad faith or gross negligence in the performance of
its duties or by reason of reckless disregard of its obligations and duties
under this Agreement.

Global Portfolio.

                                       A-1
<PAGE>

  2. EXPENSES. The Subadviser shall pay all of its expenses arising from the
performance of its obligations under Section 1.

  3. COMPENSATION. (a) As compensation for the services performed and the fa-
cilities and personnel provided by the Manager pursuant to Section 1, the Man-
ager will pay to the Subadviser each month a fee, calculated on each day dur-
ing such month, at an annual rate of .90% of the Portfolio's average daily net
assets.

  (b) If the  Subadviser  shall serve  hereunder  for less than the whole of any
month, the fee hereunder shall be prorated.

  4. PURCHASE AND SALE OF SECURITIES.  The Subadviser shall purchase  securities
from or through  and sell  securities  to or through  such  persons,  brokers or
dealers  as the  Subadviser  shall  deem  appropriate  in order to carry out the
policy with respect to allocation of portfolio  transactions as set forth in the
Registration  Statement and Prospectus(es) of the Corporation or as the Board of
Directors of the  Corporation  may direct from time to time.  In  providing  the
Portfolio with investment management and supervision,  it is recognized that the
Subadviser  will seek the most favorable  price and execution,  and,  consistent
with such policy, may give consideration to the research,  statistical and other
services  furnished by brokers or dealers to the  Subadviser for its use, to the
general  attitude of brokers or dealers  toward  investment  companies and their
support of them, and to such other  considerations  as the Board of Directors of
the Corporation may direct or authorize from time to time.

  Notwithstanding  the above,  it is  understood  that it is  desirable  for the
Portfolio that the Subadviser have access to supplemental  investment and market
research  and security  and  economic  analysis  provided by brokers who execute
brokerage  transactions  at a higher cost to the Portfolio  than may result when
allocating brokerage to other brokers on the basis of seeking the most favorable
price and execution. Therefore, the Subadviser is authorized to place orders for
the purchase and sale of securities of the Portfolio with such brokers,  subject
to review by the Corporation's Board of Directors from time to time with respect
to the extent and  continuation  of this  practice.  It is  understood  that the
services  provided by such brokers may be useful to the Subadviser in connection
with its services to other clients as well as the Portfolio.

  If, in connection  with  purchases and sales of securities  for the Portfolio,
the  Subadviser  may,  without  material  risk,  arrange to receive a soliciting
dealer's fee or other  underwriter's  or dealer's  discount or  commission,  the
Subadviser  shall,  unless  otherwise  directed by the Board of Directors of the
Corporation,  obtain such fee,  discount or  commission  and the amount  thereof
shall be applied to reduce the  compensation  to be received  by the  Subadviser
pursuant to Section 3 hereof.

                                       A-2
<PAGE>

  Nothing herein shall prohibit the Board of Directors of the  Corporation  from
approving the payment by the Portfolio of additional  compensation to others for
consulting services, supplemental research and security and economic analysis.

  5. TERM OF AGREEMENT.  This Agreement  shall continue in full force and effect
until December 31, 1998, and from year to year thereafter if such continuance is
approved in the manner required by the 1940 Act if the Subadviser shall not have
notified  the  Manager in writing at least 60 days prior to such  December 31 or
prior  to  December  31 of any year  thereafter  that it does  not  desire  such
continuance.  This Agreement may be terminated at any time,  without  payment of
penalty by the Corporation, on 60 days' written notice to the Subadviser by vote
of the Board of  Directors  of the  Corporation  or by vote of a majority of the
outstanding  voting  securities  of the  Portfolio (as defined by the 1940 Act).
This Agreement will  automatically  terminate in the event of its assignment (as
defined by the 1940 Act) or upon the termination of the Management Agreement.

  6. AMENDMENTS. This Agreement may be amended by consent of the parties
hereto provided that the consent of the Corporation is obtained in accordance
with the requirements of the 1940 Act.

  7.  MISCELLANEOUS.  This  Agreement  shall be  governed  by and  construed  in
accordance  with  the laws of the  State of New  York.  Anything  herein  to the
contrary  notwithstanding,  this Agreement shall not be construed to require, or
to impose any duty upon either of the  parties,  to do anything in  violation of
any applicable laws or regulations.

  IN WITNESS WHEREOF,  the Manager and the Subadviser have caused this Agreement
to be  executed  by their duly  authorized  officers  as of the date first above
written.

  NOW, THEREFORE, in consideration of the mutual covenants contained herein, the
parties hereto agree as follows:

  1. DUTIES OF THE  SUBADVISER.  The Subadviser will provide each Portfolio with

  4. PURCHASE AND SALE OF SECURITIES.  The Subadviser shall purchase  securities
from or through  and sell  securities  to or through  such  persons,  brokers or
dealers  as the  Subadviser  shall  deem  appropriate  in order to carry out the
policy with respect to allocation of portfolio  transactions as set forth in the
Registration  Statement and Prospectus(es) of the Corporation or as the Board of
Directors of the  Corporation  may direct from time to time.  In  providing  the

Subadviser pursuant to Section 3 hereof.

  Nothing herein shall prohibit the Board of Directors of the  Corporation  from
approving the payment by the Portfolios of additional compensation to others for
consulting services, supplemental research and security and economic analysis.

  5. TERM OF AGREEMENT.  This Agreement  shall continue in full force and effect
until December 31, 1998, and from year to year thereafter if such continuance is
approved in the manner required by the 1940 Act if the Subadviser shall not have

                              SUBADVISORY AGREEMENT

  SUBADVISORY AGREEMENT, dated      , 1998 between J. & W. SELIGMAN & CO. IN-
CORPORATED, a Delaware corporation (the "Manager") and HENDERSON INVESTMENT
MANAGEMENT LIMITED (the "Subadviser").

  WHEREAS,  the Manager has entered  into  Management  Agreements,  dated May 1,
1993,  October 1, 1994 and May 1, 1996 (the "Management  Agreements"),  with Se-
ligman Portfolios, Inc. (the "Corporation"),  an open-end diversified management
investment  company  registered  under the  Investment  Company Act of 1940,  as
amended (the "1940 Act"),  pursuant to which the Manager will render or contract
to obtain as hereinafter provided investment management services with respect to
the  Corporation's  Seligman  Henderson  International   Portfolio,  Se-  ligman
Henderson Global Smaller Companies  Portfolio,  Seligman Henderson Global Growth
Opportunities  Portfolio and Seligman Henderson Global Technology Portfolio (the
"Portfolios"),  and  to  administer  the  business  and  other  affairs  of  the
Corporation; and

  WHEREAS,  the Manager  desires to retain the Subadviser to provide  investment
advisory and other services to the Portfolios,  and the Subadviser is willing to
render such services, in each case effective July 1, 1998.

  NOW, THEREFORE, in consideration of the mutual covenants contained herein, the
parties hereto agree as follows:

  1. DUTIES OF THE SUBADVISER.  Subject in each case to the control of the Board
of Directors of the Corporation and in accordance with the objectives,  policies
and principles set forth in the Registration Statement and Prospectus(es) of the
Corporation and the  requirements  of the 1940 Act, and in conjunction  with and
under the  supervision  of the  Manager,  the  Subadviser  agrees to furnish the
Manager and the Corporation with such investment advice, research and assistance
as the Manager or the  Corporation  shall from time to time  reasonably  request
with respect to the Portfolios.  Subject to the foregoing,  the Subadviser shall
(i)  participate  in the  development  of the Portfo- lios'  overall  investment
strategy,  in the determination of country  allocations and in the determination
of sector and industry  weightings,  (ii) provide investment advice and research
to the  Portfolios  with  respect  to  existing  and  potential  investments  in
securities  of non-U.S.  issuers,  including  company  visits and meetings  with
management,  (iii) determine securities for investment, (iv) select brokers, and
(v) cause the execution of trades,  including  foreign  exchange  dealings.  The
Subadviser will make available  representatives to report in person to the Board
of Directors at least semi-annu-

                                       B-1
<PAGE>

ally on investment  results,  regulatory  compliance  and other matters that the
Manager or the Board of Directors may reasonably  request.  The Subadviser shall
also provide such reports and other  information  to the Manager or the Board of
Directors as such persons may reasonably request.

  Portfolio  accounting  and pricing  for the  Portfolios  will be the  ultimate
responsibility of a third party accounting agent or administrator;  however,  in
the event that an asset under the supervision of the Subadviser cannot be priced
by a pricing source  authorized by the Manager,  the Subadviser will provide the
third party accounting  agent or administrator  with daily prices for such asset
in accordance with the Corporation's  pricing  procedures.  Notwithstanding  the
foregoing,  the  Subadviser  will be  responsible  for  coordinating  work  with
custodians   in   respect   of  assets   under  the   Subadviser's   supervision
("Custodians"),  including  liaising as required  with  Custodians in respect of
trade settlement,  safe custody of assets,  income collection and the processing
of corporate actions.  The Subadviser will use all reasonable efforts to monitor
the performance of Custodians  within the terms of the  Corporation's  custodian
agreements  (to the extent such terms are known by the  Subadviser  or a related
entity).  With respect to the securities of issuers under the supervision of the
Subadviser,   the  Subadviser  shall  provide  executed  trade   information  to
Custodians,  third party accounting agents or administrators and/or the Manager,
which may be done via computer.

  Subject to Section 36 of the 1940 Act, the  Subadviser  shall not be liable to
the  Corporation  for any error of  judgment  or  mistake of law or for any loss
arising out of any  investment or for any act or omission in the  performance of
its duties under this  Agreement  except for willful  misfeasance,  bad faith or
negligence in the  performance of its duties or by reason of reckless  disregard
of its obligations and duties under this Agreement.

  2. EXPENSES. The Subadviser shall pay all of its expenses arising from the
performance of its obligations under Section 1.

  3. COMPENSATION. (a) As compensation for the services performed by the
Subadviser pursuant to Section 1, the Manager will pay to the Subadviser each
month a fee calculated at an annual rate of .50% of the average monthly assets
under the Subadviser's supervision.

  (b)  Average  monthly  assets  under  the  Subadviser's  supervision  shall be
determined,  for any month,  by taking the  average of the assets  (adjusted  to
reflect receivables for assets sold and payables for assets purchased) under the
Subadviser's  supervision  as of (i) the opening of business on the first day of
such month and (ii) the close of business on the last day of such month.

  (c) If the  Subadviser  shall serve  hereunder  for less than the whole of any
month, the fee hereunder shall be prorated.

                                       B-2
<PAGE>

  (d) Any fee payable to the Subadviser  under this  Agreement  shall be paid to
the Subadviser or to an affiliate of the Subadviser at an address  designated by
the Subadviser.

  4. PURCHASE AND SALE OF SECURITIES.  The Subadviser shall purchase  securities
from or through  and sell  securities  to or through  such  persons,  brokers or
dealers  as the  Subadviser  shall  deem  appropriate  in order to carry out the
policy with respect to allocation of portfolio  transactions as set forth in the
Registration  Statement and Prospectus(es) of the Corporation or as the Board of
Directors of the  Corporation  may direct from time to time.  In  providing  the
Corporation with investment  management and  supervision,  it is recognized that
the Subadviser will seek the most favorable price and execution, and, consistent
with such policy, may give consideration to the research,  statistical and other
services  furnished by brokers or dealers to the  Subadviser for its use, to the
general  attitude of brokers or dealers  toward  investment  companies and their
support of them, and to such other  considerations  as the Board of Directors of
the Corporation may direct or authorize from time to time.

  Notwithstanding  the above,  it is  understood  that it is  desirable  for the
Corporation  that the  Subadviser  have access to  supplemental  investment  and
market  research  and security  and  economic  analysis  provided by brokers who
execute  brokerage  transactions  at a higher cost to the  Corporation  than may
result when  allocating  brokerage to other  brokers on the basis of seeking the
most favorable price and execution.  Therefore,  the Subadviser is authorized to
place orders for the purchase and sale of  securities  of the  Corporation  with
such brokers,  subject to review by the  Corporation's  Board of Directors  from
time to time with respect to the extent and continuation of this practice. It is
understood  that the  services  provided  by such  brokers  may be useful to the
Subadviser  in  connection  with its  services  to other  clients as well as the
Corporation.

  If, in connection with purchases and sales of securities for the  Corporation,
the  Subadviser  may,  without  material  risk,  arrange to receive a soliciting
dealer's fee or other  underwriter's  or dealer's  discount or  commission,  the
Subadviser  shall,  unless  otherwise  directed by the Board of Directors of the
Corporation,  obtain such fee,  discount or  commission  and the amount  thereof
shall be applied to reduce the  compensation  to be received  by the  Subadviser
pursuant to Section 3 hereof.

  Nothing herein shall prohibit the Board of Directors of the  Corporation  from
approving the payment by the  Corporation of additional  compensation  to others
for  consulting  services,  supplemental  research  and  security  and  economic
analysis.

                                       B-3

  5. TERM OF AGREEMENT.  This Agreement shall become  effective July 1, 1998 and
shall  continue in full force and effect with  respect to each  Portfolio  until
December 31,  1999,  and from year to year  thereafter  if such  continuance  is
approved in the manner required by the 1940 Act if the Subadviser shall not have
notified  the  Manager in writing at least 60 days prior to such  December 31 or
prior  to  December  31 of any year  thereafter  that it does  not  desire  such
continuance.  This  Agreement  may be terminated at any time with respect to any
Portfolio,  without payment of penalty by the  Corporation,  on 60 days' written
notice to the Subadviser by vote of the Board of Directors of the Corporation or
by vote of a majority of the  outstanding  voting  securities (as defined by the
1940 Act) of such Portfolio.  This Agreement will automatically terminate in the
event of its assignment (as defined by the 1940 Act) or upon the  termination of
the Management Agreement.

  6. AMENDMENTS. This Agreement may be amended by consent of the parties
hereto provided that the consent of the Corporation is obtained in accordance
with the requirements of the 1940 Act.

  7.  MISCELLANEOUS.  This  Agreement  shall be  governed  by and  construed  in
accordance  with  the laws of the  State of New  York.  Anything  herein  to the
contrary  notwithstanding,  this Agreement shall not be construed to require, or
to impose any duty upon,  either of the parties to do anything in  violation  of
any applicable laws or regulations.

  IN WITNESS WHEREOF,  the Manager and the Subadviser have caused this Agreement
to be  executed  by their duly  authorized  officers  as of the date first above
written.
