                                 PROXY STATEMENT

            SPECIAL MEETING OF SHAREHOLDERS TO BE HELD MARCH 16, 2000

      This proxy  statement  and enclosed  form of voting  instruction  card are
being furnished in connection  with THE  SOLICITATION OF PROXIES BY THE BOARD OF
TRUSTEES  ("BOARD") OF MITCHELL  HUTCHINS  SERIES TRUST  ("Trust")  for use at a
special meeting of shareholders of STRATEGIC FIXED INCOME PORTFOLIO ("Fund"),  a
series of the Trust, to be held at 1285 Avenue of the Americas,  14th floor, New
York,  NY 10019 on March 16, 2000 at 10:30 a.m.,  Eastern  time, or as adjourned
from  time  to time  ("Meeting"),  for  the  purposes  set  forth  below.  It is
anticipated that the first mailing of proxy  statements to shareholders  will be
on or about February 16, 2000.

      The Board is soliciting proxies from shareholders of the Fund with respect
to the following proposals:

      I.    To approve or  disapprove a new  sub-advisory  contract with Pacific
            Investment Management Company;

      II.   To approve or disapprove a policy to permit the Board to appoint and
            terminate  sub-advisers,  enter  into  sub-advisory  contracts,  and
            approve  amendments to sub-advisory  contracts on behalf of the Fund
            without further shareholder approval; and

      III.  To transact such other business as may properly come before the
            Meeting.


      The Shares of  beneficial  interest  ("Shares")  of the Fund are currently
sold only to the separate  accounts  ("Separate  Accounts") of PaineWebber  Life
Insurance Company,  American Republic Insurance Company and Keyport Benefit Life
Insurance  Company  (collectively,  the  "Companies") to fund the benefits under
variable annuity contracts ("Contracts") issued by the Companies. The Trust is a
registered,  management  investment  company under the Investment Company Act of
1940, as amended  ("1940  Act"),  and is organized as a  Massachusetts  business
trust.  In  accordance  with their view of applicable  law, the  Companies  will
solicit voting  instructions  from the owners of Contracts  relating to the Fund
("Contract  Owners")  with  respect  to the  matters  set  forth  in this  Proxy
Statement.  In connection  with the  solicitation  of voting  instructions,  the
Companies will furnish a copy of this Proxy Statement to all Contract Owners.

      Contract  Owners  will be  entitled  to be present at the Meeting and give


<PAGE>


voting  instructions for Shares  attributable to their Contracts as of the close
of business on January 21, 2000 ("Record  Date").  There were 582,335  Shares of
the Fund  outstanding  and entitled to vote as of the Record Date. On the Record
Date, the Separate  Accounts of PaineWebber  Life  Insurance  Company,  American
Republic  Insurance  Company and Keyport Benefit Life Insurance Company owned of
record 58%, 40% and 2%, respectively, of the outstanding Shares of the Fund.

      The Companies  will vote Shares of the Fund held by the Separate  Accounts
in accordance  with voting  instructions  received by the Contract  Owners.  The
Companies  will vote Shares of the Fund for which a voting  instruction  card is
returned  signed and dated but with no  specific  instructions  as to a proposal
"FOR" the  proposal.  The  Companies  will vote  Shares of the Fund for which no
voting  instruction  cards are returned in the same  proportion as Shares of the
Fund for which voting instruction cards have been returned.

      The  presence  in person or by proxy of the  holders of a majority  of the
outstanding  Shares  of the Fund is  required  to  constitute  a  quorum  at the
Meeting.  Abstentions  will  be  counted  as  Shares  present  for  purposes  of
determining whether a quorum is present but will not be voted for or against any
adjournment  or  proposal.  Thus,  abstentions  will  have the same  effect as a
negative vote on adjournment and on the proposals, which require the affirmative
vote of a specified portion of the Fund's outstanding Shares.

      In the absence of a quorum or in the event that a quorum is present at the
Meeting but  sufficient  votes to approve any  proposal  are not  received,  the
persons named as proxies may propose one or more  adjournments of the Meeting to
permit  further  solicitation  of  proxies or to obtain  the vote  required  for
approval  of one or more  proposals.  Any  such  adjournment  will  require  the
affirmative  vote of a majority of those  Shares  represented  at the Meeting in
person or by proxy.  The persons  named as proxies will vote those proxies which
they are entitled to vote "FOR" the proposal in favor of such an adjournment and
will vote those proxies  required to be voted "AGAINST" the proposal against any
such  adjournment.  A shareholder  vote may be taken prior to any adjournment of
the Meeting on any  proposal for which there are  sufficient  votes for approval
and it is  otherwise  appropriate,  even though the Meeting is  adjourned  as to
other proposals.

      You  may  revoke  any  voting   instructions   by  giving  another  voting
instruction  card  or  by  letter  or  telegram   revoking  the  initial  voting
instructions.  To  be  effective,  your  revocation  must  be  received  by  the
appropriate Company prior to the Meeting and must indicate your name and account
number.  In addition,  if you attend the Meeting in person you may, if you wish,
provide  voting  instructions  at the  Meeting,  thereby  canceling  any  voting
instructions  previously  given.  Attendance in person at the Meeting by itself,
however, will not revoke a previously tendered voting instruction card.


                                      -2-

      Each full Share of the Fund is  entitled  to one vote and each  fractional
Share is  entitled  to a  proportionate  Share of one vote with  respect to each
matter  voted  upon by  shareholders  of the  Fund.  Information  about the vote
necessary  with respect to each proposal is discussed  below in connection  with
the proposal.

      THE TRUST  WILL  FURNISH  TO THE  COMPANIES  AND TO THE  CONTRACT  OWNERS,
WITHOUT  CHARGE,  COPIES  OF THE MOST  RECENT  ANNUAL  REPORT  AND  MOST  RECENT
SEMI-ANNUAL  REPORT SUCCEEDING SUCH ANNUAL REPORT UPON REQUEST.  CONTRACT OWNERS
MAY REQUEST THESE REPORTS BY WRITING TO ANNUITY ADMINISTRATION,  601 6TH AVENUE,
DES MOINES, IOWA 50334 OR BY CALLING 1-800-367-6058.


      PROPOSAL I: TO APPROVE OR DISAPPROVE A NEW SUB-ADVISORY CONTRACT
      WITH PACIFIC INVESTMENT MANAGEMENT COMPANY

      INTRODUCTION.  Since September 1995, Pacific Investment Management Company
("PIMCO")  has  served  as  investment  sub-adviser  to the Fund  pursuant  to a
sub-advisory contract ("Current  Sub-Advisory  Contract").  PIMCO will undergo a
change of control as a result of the  consummation of the transaction  described
below, resulting in the assignment, and therefore automatic termination,  of the
Current  Sub-Advisory  Contract.  Upon  completion  of  the  transaction,  PIMCO
Advisors, L.P. ("PIMCO Advisors") and its subsidiaries, including PIMCO, will be
controlled by Allianz of America,  Inc.  ("Allianz of America").  It is proposed
that PIMCO  continue to serve as investment  sub-adviser  of the Fund  following
completion of the transaction. Therefore, in connection with the transaction and
as required by the  Investment  Company Act of 1940,  as amended  ("1940  Act"),
shareholders  of the Fund  are  being  asked  in  Proposal  I to  approve  a new
sub-advisory contract which is substantially similar to the Current Sub-Advisory
Contract ("New Sub-Advisory  Contract") except as described herein. The Board of
the Trust recommends that shareholders approve the New Sub-Advisory  Contract, a
form of which is attached as Appendix A.

      PIMCO is a subsidiary  partnership of PIMCO Advisors. The general partners
of PIMCO Advisors are PIMCO Partners,  G.P. ("Partners G.P.") and PIMCO Advisors
Holdings  L.P.  ("PAH").  Partners G.P. is a general  partnership  between PIMCO
Holding LLC, a Delaware limited  liability  company and an indirect wholly owned
subsidiary  of  Pacific  Life  Insurance  Company  ("Pacific  Life"),  and PIMCO
Partners LLC ("Partners LLC"), a California limited liability company controlled
by the current  managing  directors and two former  managing  directors of PIMCO
("Managing  Directors").  PAH is a publicly traded Delaware limited  partnership
and its primary source of income is its proportionate share of the net income of
PIMCO Advisors. Partners G.P. is the sole general partner of PAH. The address of
all the above  entities,  with the  exception  of Pacific  Life,  is 800 Newport
Center Drive,  Newport Beach,  California 92660.  Pacific Life is located at 700
Newport Center Drive, Newport Beach, California 92660.

      DESCRIPTION OF THE TRANSACTION.  On October 31, 1999, PIMCO Advisors, PAH,
Partners G.P., certain of their affiliates, Allianz of America and certain other


                                      -3-
<PAGE>


parties  named  therein  entered  into an  Implementation  and Merger  Agreement
("Merger  Agreement") pursuant to which Allianz of America will acquire majority
ownership of PIMCO Advisors ("Transaction").

      The Merger  Agreement  provides for the  acquisition  of PAH by Allianz of
America  through a merger of a  subsidiary  of Allianz of America  with and into
PAH. In the merger,  each of the  outstanding  limited  partnership  and general
partner  units in PAH will be  converted  into the right to  receive  in cash an
amount  per unit  equal to  $38.75,  subject  to a  downward  adjustment  if the
aggregate annualized  investment advisory and sub-advisory fees for all accounts
managed  by  PIMCO  Advisors  and  its  subsidiaries,  expressed  as a  "revenue
run-rate,"  declines  (excluding  market-based  changes) below a specified level
("Unit  Transaction  Price").  In no event  will the Unit  Transaction  Price be
reduced  below  $31.00 per unit.  As a result of the merger,  PAH will become an
indirect wholly owned subsidiary of Allianz of America.

      Following the merger, subsidiaries of Allianz of America will, in a series
of  transactions,  acquire for cash  additional  partnership  interests in PIMCO
Advisors,  bringing its ownership  interest in PIMCO  Advisors to  approximately
70%,  including the  approximately 44% interest held through PAH. As part of the
Transaction,  a  subsidiary  of Allianz of America will  acquire  Partners  G.P.
through an acquisition of the managing general partner interest in Partners G.P.
from  Partners  LLC  (the  managing   general  partner  of  Partners  G.P.)  for
approximately $5.5 million and of the member interests in Partners G.P. that are
indirectly owned by Pacific Life. Pacific Life, which through  subsidiaries owns
approximately a 30% interest in PIMCO Advisors, will retain an indirect interest
in PIMCO Advisors following the closing. As a result of the Transaction, Allianz
of America will control PIMCO Advisors, having acquired approximately 70% of the
outstanding partnership interests in PIMCO Advisors for a total consideration of
approximately  $3.3 billion,  while the  remainder  will continue to be owned by
Pacific Life.

      In  connection  with the  closing,  Allianz of  America  will enter into a
put/call  arrangement  for the possible  disposition of Pacific Life's  indirect
interest in PIMCO Advisors. The put option held by Pacific Life will allow it to
require  Allianz of America,  on the last business day of each calendar  quarter
following the closing of the Transaction,  to purchase at a formula-based  price
all of the PIMCO  Advisors  units owned  directly or indirectly by Pacific Life.
The call option held by Allianz of America will allow it, beginning  January 31,
2003 or upon a change in control of Pacific  Life,  to require  Pacific  Life to
sell or cause to be sold to Allianz of America,  at the same  price,  all of the
PIMCO Advisors units owned directly or indirectly by Pacific Life.

      The  Transaction  is  expected  to be  completed  by the end of the  first
quarter of 2000,  although  there is no assurance that the  Transaction  will be
completed.  Completion of the  Transaction is subject to a number of conditions,
including, among others, (i) the approval of the public unitholders of PAH, (ii)
the receipt of certain regulatory  approvals,  and (iii) PIMCO Advisors' revenue
run-rate  (excluding  market-based  changes) for all  accounts  managed by PIMCO
Advisors  and its  subsidiaries  being at least 75% of the  September  30,  1999
revenue  run-rate  amount.  Approval  of the New  Sub-Advisory  Contract  by the
shareholders  of the Fund will help  satisfy  condition  (iii)  described in the
preceding  sentence by maintaining  PIMCO's  sub-advisory  relationship with the


                                      -4-
<PAGE>


Fund.  If  the  Transaction  is  not  completed  for  any  reason,  the  Current
Sub-Advisory  Contract will remain in effect.  In the event the New Sub-Advisory
Contract  is not  approved by the Fund's  shareholders  and the  Transaction  is
completed, the Board will consider appropriate action.

      Pursuant to the Merger Agreement, PIMCO Advisors and PIMCO will enter into
employment,  retention  and incentive  arrangements  with key employees of PIMCO
Advisors and PIMCO. These benefits include new employment agreements,  retention
and incentive  awards vesting over a term of years and restricted  stock grants.
In  addition,  certain key  employees  of PIMCO  Advisors'  investment  advisory
subsidiaries   will  receive   payments  in  respect  of   previously   existing
non-competition  arrangements  in connection  with the acquisition by Allianz of
America of the PIMCO Advisors units on which such arrangements were based.

      Allianz of America and each of the other  parties to the Merger  Agreement
have agreed to use  reasonable  best efforts to ensure  compliance  with Section
15(f) of the 1940 Act as it applies to the Transaction. Section 15(f) provides a
non-exclusive  safe  harbor for PIMCO or any  affiliated  persons to receive any
amount or benefit in connection  with the "change of control" if two  conditions
are met.  First,  the  Transaction  must not  impose  any  unfair  burden on any
investment company client of the adviser,  including the Trust.  Second,  during
the three-year  period after the Transaction,  at least 75% of the board of each
investment  company client,  including the Trust, must not be interested persons
of PIMCO (or any predecessor or successor adviser). Currently, no trustee of the
Trust is an interested  person of PIMCO, and PIMCO has advised the Board that it
is not aware of any circumstances arising from the Transaction that would impose
an unfair burden on the Fund.

      POST-TRANSACTION   STRUCTURE  AND  OPERATIONS.   Upon  completion  of  the
Transaction,  PIMCO  Advisors and its  subsidiaries,  including  PIMCO,  will be
controlled by Allianz of America.  Allianz of America is a holding  company that
owns several  insurance and financial  service  companies and is a subsidiary of
Allianz AG. Allianz of America will control PIMCO Advisors  through its managing
member interest in Pacific-Allianz  Partners LLC ("PacPartners LLC"), which will
be the sole general partner of PIMCO Advisors  following the Transaction.  While
Allianz  of America  will  control  PacPartners  LLC,  Pacific  Life will hold a
portion of its  continuing  interest  in PIMCO  Advisors  through an interest in
PacPartners LLC. Allianz of America, through subsidiaries,  will be the managing
member of PacPartners  LLC and will have the full authority and control over all
actions  taken by  PacPartners  LLC as the  general  partner of PIMCO  Advisors,
provided  that  Pacific  Life's  consent is required  for certain  extraordinary
actions.

      Operationally,  PIMCO is  expected to remain  independent  and to lead the
global fixed income investment efforts of Allianz AG. In this regard, PIMCO will
coordinate its activities with Allianz Asset Management ("AAM"), a subsidiary of
Allianz AG that  coordinates  global  Allianz asset  management  activities.  To
permit the  provision  of advisory  services to non-U.S.  clients of Allianz AG,
PIMCO personnel,  including personnel with portfolio  management  responsibility
for the  Fund,  may  become  affiliated  with  AAM or  other  Allianz-controlled
advisory firms. PIMCO also may call upon the research capabilities and resources
of  Allianz  AG  and  its  advisory  affiliates  in  connection  with  providing
investment  advice to its clients.  PIMCO is  currently  expected to continue to
operate in the United States under its existing name.

      Both William S.  Thompson,  Jr., the current  Chief  Executive  Officer of
PIMCO, and William H. Gross, the current Chief Investment Officer of PIMCO, will
have roles on the Executive  Committee of AAM, with Mr. Thompson  serving as the
Executive  Committee's  Deputy Chairman.  Messrs.  Thompson and Gross will enter
into employment  contracts with a term of seven years following the Transaction.
Other  key  employees  of PIMCO  and  PIMCO  Advisors,  including  the  Managing
Directors,  have also contractually  agreed to remain with PIMCO for significant
periods following the Transaction.

      Significant  institutional  shareholders of Allianz AG currently  include,
among  others,  Dresdner  Bank AG,  Deutsche  Bank AG,  Munich  Reinsurance  and
HypoVereinsbank.  Following completion of the Transaction,  Dresdner Bank AG and
Deutsche Bank AG, as well as certain  broker-dealers  that might be deemed to be
affiliated  with these entities,  such as Bankers Trust Company,  BT Alex Brown,
Inc., Deutsche Bank Securities, Inc. and Dresdner Kleinwort Benson North America
LLC (collectively, the "Affiliated Brokers"), may be considered to be affiliated
persons of PIMCO.  Once the  Transaction is completed,  absent an exemption from
the U.S.  Securities and Exchange  Commission  ("SEC") or other relief, the Fund
generally  would be precluded from  effecting  principal  transactions  with the
Affiliated Brokers,  and their ability to purchase securities being underwritten
by an  Affiliated  Broker  or to  utilize  the  Affiliated  Brokers  for  agency
transactions  would be subject to  restrictions.  PIMCO  does not  believe  that
applicable  restrictions on transactions  with the Affiliated  Brokers described
above will materially  adversely  affect its ability,  post-closing,  to provide
services  to  the  Fund,   the  Fund's  ability  to  take  advantage  of  market
opportunities,  or the Fund's overall performance. Other series of the Trust for
which PIMCO (or an affiliate) does not serve as an investment  sub-adviser would
not, in general, be subject to these same restrictions post-closing.

      ANTICIPATED IMPACT OF THE TRANSACTION ON MANAGEMENT OF THE FUND. PIMCO has
received structural and contractual protections as terms of the Transaction that
ensure  PIMCO's  operational  autonomy and  continuity of  management.  PIMCO is
confident  that  Allianz AG is committed to the people and process that have led
to  PIMCO's  success  over the  years.  Accordingly,  PIMCO has  represented  to
Mitchell  Hutchins Asset  Management Inc.  ("Mitchell  Hutchins") and the Fund's
Board  that the  Transaction  should  have no  immediate  impact,  other than as
already  noted  above,  on the  management  of the Fund or PIMCO's  capacity  to
provide the type,  quality,  or quantity of services that it currently provides,
and the Fund should  continue to receive the same high quality of service  after
the  Transaction.   As  discussed  below,  however,   PIMCO  believes  that  the
Transaction offers the potential to enhance  significantly its future ability to
deliver quality sub-advisory services.

      THE  BENEFITS  OF THE  TRANSACTION.  PIMCO  has  represented  to  Mitchell
Hutchins that it anticipates  that the Transaction  with Allianz AG will benefit
PIMCO and the Fund in a variety of ways, including the following:

      o PIMCO's  investment  expertise will be enhanced  because of the business
        experience and relationships that Allianz AG has built around the globe,
        particularly in Europe.  PIMCO's access to European markets and business
        opportunities  will be greatly  enhanced by Allianz AG's  experience and
        relationships.  The  combined  global  resources of PIMCO and Allianz AG
        will  allow  PIMCO to take  advantage  of the  growth  in  international
        markets and the explosive  potential  for premier money  managers in the
        global marketplace.

      o Allianz  AG has a team of  fixed  income  professionals  in  place  that
        currently manages more than $100 billion in assets. Integration of these
        professionals  and assets with PIMCO  provides an excellent  opportunity
        for furthering PIMCO's global fixed income expertise.

      o The  rotation of many of PIMCO's key  investment  professionals  through
        international  offices and overseas  personnel  through  PIMCO's offices
        will result in more seasoned professionals with global experience.

      o The combination will provide  additional career  opportunities for PIMCO
        professionals, furthering PIMCO's ability to attract and retain the best
        people.

      o Allianz  AG has a  stated  growth  strategy  to be  among  the top  five
        providers  of its  services in the world's key  markets,  which is a key
        factor in PIMCO's decision to proceed with the Transaction. The combined
        entity will be the sixth largest  investment  manager in the world.  The
        Transaction will significantly increase assets under PIMCO's management,
        and will  offer the  opportunity  for  continued  growth in the  future.
        Strong  relative  investment  results  depend  on a  sound,  disciplined
        investment  process and  effective  execution;  size can be a benefit to
        both.

      COMPARISON OF THE CURRENT AND NEW SUB-ADVISORY  CONTRACTS.  The provisions
of  the  Current  Sub-Advisory   Contract  and  the  New  Sub-Advisory  Contract
(collectively, the "Sub-Advisory Contracts") are substantially similar.

      The Current  Sub-Advisory  Contract,  dated  September 21, 1995,  was last
approved by the Board,  including a majority of the Trustees who are not parties
to the Current  Sub-Advisory  Contract or interested  persons (as defined by the
1940 Act) of the Trust (other than as Trustees of the Trust),  Mitchell Hutchins
or PIMCO  ("Independent  Trustees"),  at a  meeting  held on May 13,  1999.  The
Current Sub-Advisory Contract was last submitted to shareholders for approval on
September  21,  1995,  for  the  purpose  of  implementing  the  Fund's  current
sub-advisory  arrangements.  If the Transaction is not  consummated,  PIMCO will
continue  to serve as  investment  sub-adviser  to the Fund  under  the  Current
Sub-Advisory Contract.

      PIMCO has advised  the Fund that it  currently  anticipates  that the same
persons  responsible  for management of the Fund under the Current  Sub-Advisory


                                      -7-
<PAGE>


Contract will continue to be  responsible  for  management of the Fund under the
New  Sub-Advisory  Contract.  PIMCO  has  advised  the  Trust  that it does  not
anticipate that the Transaction will cause any reduction in the quality or types
of  services  now  provided  to the Fund or have any  adverse  effect on PIMCO's
ability to fulfill its obligations to the Fund.

      Under both Sub-Advisory  Contracts,  PIMCO is responsible,  subject to the
supervision  of the Board  and  Mitchell  Hutchins,  for the  actual  investment
management of the Fund's assets,  including placing purchase and sell orders for
investments and for other related  transactions.  Under those  contracts,  PIMCO
agrees to  provide  a  continuous  investment  program  for the Fund,  including
investment  research and management.  In addition,  both contracts  provide that
PIMCO  will  manage  the  Fund's   assets  so  that  the  Fund   satisfies   the
diversification   requirements  under  Section  817(h)  of  the  Code.  The  New
Sub-Advisory  Contract provides that PIMCO may seek research assistance and rely
upon resources  available to it through its  affiliated  companies to the extent
that such actions would not constitute an "assignment"  for purposes of the 1940
Act.  However,  such  assistance  and/or  reliance will not relieve PIMCO of its
obligations  under  the  New  Sub-Advisory   Contract.  In  addition,   the  New
Sub-Advisory  Contract  provides  that  PIMCO  will vote  proxies  of issuers of
securities held by the Fund. Both  Sub-Advisory  Contracts  recognize that PIMCO
may, under certain circumstances,  pay higher brokerage commissions by executing
portfolio  transactions with brokers who provide PIMCO with research,  analysis,
advice or similar services.  Both Sub-Advisory Contracts also provide that PIMCO
will maintain all books and records  required to be maintained by PIMCO pursuant
to the  1940 Act and the  rules  and  regulations  promulgated  thereunder  with
respect to  transactions on behalf of the Fund. In addition,  both  Sub-Advisory
Contracts  also provide that PIMCO will furnish the Board and Mitchell  Hutchins
with  economic  and  investment  analyses  and  reports as the Board or Mitchell
Hutchins  reasonably may request,  will provide the Board and Mitchell  Hutchins
with  quarterly  reports  setting  forth the Fund's  performance,  and will make
available  to the  Board  and  Mitchell  Hutchins  upon  request  any  economic,
statistical  and investment  services  normally  available to other customers of
PIMCO.

      Both Sub-Advisory Contracts provide that PIMCO is entitled to receive from
Mitchell  Hutchins,  and not the Fund, a sub-advisory fee,  calculated daily and
paid monthly, at an annual rate of 0.25% of the Fund's average daily net assets.
In addition,  both Sub-Advisory  Contracts state that for those periods in which
Mitchell  Hutchins has agreed to waive all or a portion of its  management  fee,
Mitchell  Hutchins may ask PIMCO to waive the same  proportion of its fees,  but
PIMCO is under no obligation to do so. PIMCO bears all expenses  incurred by it
(and not the Fund) in  connection  with its  services  under  each  Sub-Advisory
Contract.  Neither  the  Trust  nor  the  Fund  has  any  responsibility  to pay
sub-advisory  fees to PIMCO.  During the Fund's last fiscal year ended  December
31,  1999,  Mitchell  Hutchins,  and  not  the  Fund,  paid  PIMCO  $20,153  for
sub-advisory services.

      Both Sub-Advisory  Contracts provide that PIMCO will not be liable for any
error of  judgment or mistake of law or for any loss  suffered by the Fund,  the
Trust, its  shareholders or Mitchell  Hutchins in connection with the matters to
which the Sub-Advisory  Contract  relates,  except a loss resulting from willful
misfeasance, bad faith or gross negligence on its part in the performance of its
duties or from reckless  disregard by it of its obligations and duties under the
Sub-Advisory Contract.


                                      -8-
<PAGE>


      Moreover,  both Sub-Advisory  Contracts  provide for termination,  without
payment of any  penalty,  by vote of the Board or by a vote of a majority of the
Fund's  outstanding  voting  securities  on 60 days'  written  notice  to PIMCO.
Mitchell Hutchins may also terminate the Sub-Advisory Contracts, without payment
of any penalty:  (1) on 120 days' written notice to PIMCO;  (2) immediately upon
material  breach by PIMCO of  representations  and  warranties  contained in the
Sub-Advisory  Contracts;  or (3) immediately  if, in the reasonable  judgment of
Mitchell Hutchins,  PIMCO becomes unable to discharge its duties and obligations
under the  Sub-Advisory  Contract,  including  circumstances  such as  financial
insolvency of PIMCO or other circumstances that could adversely affect the Fund.
In addition, PIMCO may terminate the Sub-Advisory Contracts,  without payment of
any penalty, on 120 days' written notice to Mitchell Hutchins.  The Sub-Advisory
Contracts  terminate  automatically  in the event of "assignment" (as defined in
the 1940 Act).

      The New Sub-Advisory  Contract  includes a few additional  provisions.  It
provides  that  neither  PIMCO nor any of its  affiliates  will in any way refer
directly or indirectly to its relationship  with the Trust,  the Fund,  Mitchell
Hutchins or any of their respective  affiliates in offering,  marketing or other
promotional  materials without the express written consent of Mitchell Hutchins.
It also stipulates that PIMCO will notify Mitchell  Hutchins if there is a death
or withdrawal of any of its partners, upon admission of any partners or upon any
other changes in its membership.

      Mitchell  Hutchins and the Trust have received an order of exemption  from
the  SEC  that  permits  Mitchell   Hutchins  not  only  to  terminate  the  New
Sub-Advisory Contract but also to appoint a new sub-adviser, subject to approval
by the Board of the Trust but not by the  holders of the  outstanding  Shares of
the Trust or the Fund.  Shareholders  must approve this policy  before it may be
implemented. See Proposal II for more information.

      At the November 11, 1999 Board meeting, the New Sub-Advisory  Contract was
approved  unanimously by the Board,  including all of the Independent  Trustees.
The New  Sub-Advisory  Contract,  as approved  by the Board,  is  submitted  for
approval by the shareholders of the Fund.

      If the New Sub-Advisory  Contract is approved by the Fund's  shareholders,
it will take effect  immediately  upon the closing of the  Transaction.  The New
Sub-Advisory Contract will remain in effect for two years from the date it takes
effect and,  unless  earlier  terminated,  will  continue from year to year with
respect to the Fund,  provided that each such continuance is approved  annually,
(i)  by the  Board  or by the  vote  of a  majority  of the  outstanding  voting
securities of the Fund,  and, in either case, (ii) by a majority of the Trustees
who are not parties to the New Sub-Advisory  Contract or "interested persons" of
any such party (other than as Trustees of the Trust).  In the event that, due to
adjournments of the meeting,  the Transaction closes before Shareholders approve
the  New  Sub-Advisory   Contract,  the  Board,  including  a  majority  of  the
Independent Trustees,  has authorized an interim Sub-Advisory Contract which has
the same terms as the New  Sub-Advisory  Contract.  Pursuant to Rule 15a-4 under
the 1940 Act this  interim  contract  may  continue in effect for up to 150 days
after  the  automatic  termination  of the  Current  Sub-Advisory  Contract  and
sub-advisory  fees  would  be  held in an  escrow  account  pending  shareholder
approval.

      EVALUATION BY THE BOARD.  The Board has determined  that, by approving the
New  Sub-Advisory  Contract  on behalf of the  Fund,  the Trust can best  assure
itself that services  currently  provided to the Fund by PIMCO, its officers and
employees,  will continue without interruption after the Transaction.  The Board
believes that,  like the Current  Sub-Advisory  Contract,  the New  Sub-Advisory
Contract will enable the Fund to obtain high quality  services at a cost that is
appropriate,  reasonable,  and  in  the  best  interests  of the  Fund  and  its
shareholders.


                                      -9-
<PAGE>


      In determining  whether it was appropriate to approve the New Sub-Advisory
Contract and to recommend  approval to  shareholders,  the Board,  including the
Independent Trustees,  considered various materials and representations provided
by  PIMCO,   including  information   concerning   compensation  and  employment
arrangements to be implemented in connection with the Transaction and considered
a report provided by Allianz AG.

      Information  considered by the Trustees included,  among other things, the
following:  (1) PIMCO's  representation  that the same persons  responsible  for
management of the Fund under the Current  Sub-Advisory  Contract are expected to
continue to manage the Fund under the New Sub-Advisory Contract, thus helping to
ensure  continuity of management;  (2) the  compensation to be received by PIMCO
under the New Sub-Advisory  Contract is the same as the compensation  paid under
the Current Sub-Advisory Contract,  which the Board previously has determined to
be fair and  reasonable;  (3)  PIMCO's  representation  that it will not seek to
increase the rate of sub-advisory fees paid by the Fund for a period of at least
two years  following the  Transaction;  (4) the  substantial  commonality of the
terms and  provisions  of the New  Sub-Advisory  Contract  with the terms of the
Current Sub-Advisory  Contract; (5) representations made by PIMCO concerning the
impact of affiliated brokerage  relationships on its ability to provide services
to the Fund, and on the Fund's ability to engage in portfolio transactions;  (6)
the representations by PIMCO and Allianz AG that the integration of Allianz AG's
and PIMCO's operations could produce benefits to shareholders  through economies
of scale,  expansion  of PIMCO's  investment  expertise  through the addition of
Allianz   AG's  fixed   income   investment   business   expertise   and  global
relationships,  the expansion of PIMCO's investment research  capabilities,  and
the ability to enhance the quality of services provided to shareholders; (7) the
nature  and  quality  of the  services  rendered  by  PIMCO  under  the  Current
Sub-Advisory  Contract;  (8) the results achieved by PIMCO for the Fund; and (9)
the  quality  of the  personnel,  operations,  financial  condition,  investment
management capabilities, methodologies, and performance of PIMCO.

      Based upon its review,  the Board  determined  that,  by approving the New
Sub-Advisory  Contract,  the Fund can best be assured that  services  from PIMCO
will be provided  without  interruption.  The Board also determined that the New
Sub-Advisory Contract is in the best interests of the Fund and its shareholders.
Accordingly,  after  consideration of the above factors,  and such other factors
and information it considered  relevant,  the Board unanimously approved the New
Sub-Advisory  Contract  and  voted  to  recommend  its  approval  by the  Fund's
shareholders.

      REQUIRED VOTE.  Approval of Proposal I requires the vote of a "majority of
the  outstanding  voting  securities"  of the Fund,  as defined in the 1940 Act,
which means the vote of 67% or more of the voting securities of the Fund present
at the Meeting, if the holders of more than 50% of the outstanding Shares of the
Fund are present or  represented  by proxy,  or the vote of more than 50% of the
outstanding voting securities of the Fund, whichever is less.

                   THE BOARD RECOMMENDS THAT CONTRACT OWNERS VOTE
                                "FOR" PROPOSAL I.

      PROPOSAL  II:  TO  APPROVE A POLICY TO  PERMIT  THE BOARD OF  TRUSTEES  TO
      APPOINT AND TERMINATE  SUB-ADVISERS,  TO ENTER INTO SUB-ADVISORY CONTRACTS


                                      -10-
<PAGE>


      AND TO APPROVE AMENDMENTS TO THE SUB-ADVISORY  CONTRACTS, ON BEHALF OF THE
      FUND WITHOUT FURTHER SHAREHOLDER APPROVAL.

      SUMMARY.  At the Board meeting on July 9, 1998,  the Board  approved,  and
recommended that  shareholders of the Fund approve,  a policy to permit Mitchell
Hutchins,  subject to the  approval  of the  Board,  to  appoint  and  terminate
sub-advisers,  to enter into  sub-advisory  contracts and to amend  sub-advisory
contracts  on  behalf  of  the  Fund  without   further   shareholder   approval
("Sub-Adviser  Approval Policy"). At the Board Meeting on November 11, 1999, the
Board approved submission of the Sub-Adviser  Approval Policy to shareholders at
this Meeting.

      THE SECTION 15 EXEMPTIVE ORDER. Implementation of the Sub-Adviser Approval
Policy requires an order from the SEC exempting the Trust from the provisions of
Section 15(a) of the 1940 Act and Rule 18f-2 thereunder.  This Order was granted
by the SEC on January 19, 1999.  Absent this order,  the  provisions of the 1940
Act require that  shareholders of the Fund approve a new  sub-advisory  contract
with the sub-adviser as well as material amendments to an existing  sub-advisory
contract.  If  shareholders  approve this  proposal,  Mitchell  Hutchins will be
authorized, subject to approval by the Board, to evaluate, select and retain new
sub-advisers  for the Fund or modify the Fund's existing  Sub-Advisory  Contract
(including  termination)  without  obtaining  further  approval  of  the  Fund's
shareholders whenever Mitchell Hutchins and the Board believe these actions will
benefit the Fund and its shareholders.  As explained below,  shareholders  would
receive detailed  information  regarding any change in sub-adviser or a material
change to the sub-advisory contract.

      CURRENT SUB-ADVISER APPROVAL PROCESS. Currently,  Mitchell Hutchins enters
into  sub-advisory  contracts  pursuant to which the  selected  sub-adviser  has
authority to provide the Fund with advice  concerning the investment  management
of all (or a portion) of the Fund's  assets.  The  sub-adviser  determines  what
securities shall be purchased, what securities shall be sold and what portion of
the Fund's assets shall remain uninvested.  For these  sub-advisory  services to
the Fund,  Mitchell  Hutchins pays the sub-adviser a monthly fee as specified in
the sub-advisory  contract.  The sub-adviser bears its own expenses of providing
sub-advisory  services  to the  Fund.  Neither  the  Trust  nor the Fund has any
responsibility  to  pay  sub-advisory  fees  to  the  sub-adviser.   The  Fund's
sub-advisory  contracts  are  subject to approval  by the Board,  including  the
Independent  Trustees,  and in the  absence of  exemptive  relief  from the SEC,
approval by the Fund's shareholders.

      PROPOSED SUB-ADVISER APPROVAL POLICY. Approval of the Sub-Adviser Approval
Policy will not affect any of the requirements under the federal securities laws
that govern the Trust, the Fund,  Mitchell  Hutchins,  any  sub-adviser,  or any
sub-advisory contract,  other than the requirement to call and hold a meeting of
the Fund's  shareholders  for the purpose of approving a sub-advisory  contract.
The Board,  including the  Independent  Trustees,  will continue to evaluate and
approve  all  new  sub-advisory  contracts  between  Mitchell  Hutchins  and any
sub-adviser  as well as all  changes  to  existing  sub-advisory  contracts.  In
addition,  the Trust and Mitchell Hutchins will be subject to several conditions
imposed by the SEC to ensure that the interests of the Fund's  shareholders (and
Contract Owners) are adequately  protected whenever Mitchell Hutchins acts under
the Sub-Adviser  Approval Policy.  Furthermore,  within 90 days of any change in
sub-adviser  or a material  change to a  sub-advisory  contract,  the Trust will


                                      -11-
<PAGE>


provide the Fund's  shareholders  with an  information  statement  that contains
substantially  the  same  relevant   information  about  the  sub-adviser,   the
sub-advisory contract and the sub-advisory fee that would be required to be sent
to the Fund's shareholders in a proxy statement.  This statement will inform the
Fund's  shareholders  of the new  sub-advisory  arrangements.  If not satisfied,
shareholders  would be able to exchange or redeem their  Shares.  The  Companies
would forward the information to the Contract Owners so that the Contract Owners
would be advised of the new  sub-advisory  arrangements.  If not satisfied,  the
Contract  Owners  could  allocate  the  portion  of the value of their  Contract
invested in the Fund to another investment.

      Shareholder approval of this Proposal II will not result in an increase or
decrease in the total  amount of  investment  advisory  fees paid by the Fund to
Mitchell  Hutchins.  If the Trust  implements the Sub-Adviser  Approval  Policy,
Mitchell   Hutchins,   pursuant  to  the   Trust's   Investment   Advisory   and
Administration  Contract, will continue to provide the same level of management
and administrative services to the Fund that it has always provided.

      The  Sub-Adviser  Approval  Policy  permits  Mitchell  Hutchins  to change
sub-advisers or sub-advisory  arrangements in the following types of situations:
(1) the sub-adviser has a record of substandard performance;  (2) the individual
employees  responsible  for  portfolio  management  of the  Fund  move  from the
sub-adviser  to  another  investment  advisory  firm;  (3)  there is a change of
control of the  sub-adviser;  (4) Mitchell  Hutchins  decides to  diversify  the
Fund's  management  by  adding  another  sub-adviser;  (5)  there is a change in
investment style of the Fund; and (6) Mitchell  Hutchins  negotiates a reduction
(or the  sub-adviser  negotiates an increase) in the portion of the advisory fee
that Mitchell  Hutchins pays to the sub-adviser.  Furthermore,  where there is a
decrease  in  a  sub-adviser's  compensation  paid  by  Mitchell  Hutchins,  the
concomitant  increase in the  compensation  available  for retention by Mitchell
Hutchins  would not be deemed to be an increase in  advisory  compensation  that
requires a shareholder meeting. The Sub-Adviser Approval Policy will not be used
to approve any  sub-adviser  that is affiliated  with Mitchell  Hutchins as that
term is used in the 1940 Act or materially amend any sub-advisory  contract with
an affiliated sub-adviser.

      REASONS FOR  REQUESTING  SECTION 15 EXEMPTIVE  RELIEF.  The Board believes
that  providing  Mitchell  Hutchins  with maximum  flexibility  to perform those
duties  that  shareholders  expect  Mitchell  Hutchins  to   perform--selecting,
supervising and evaluating sub-advisers--without incurring the unnecessary delay
or expense of obtaining further shareholder approval is in the best interests of
the Fund's  shareholders (and Contract Owners) because it will allow the Fund to
operate more efficiently. Currently, in order for Mitchell Hutchins to appoint a
sub-adviser or materially  modify a sub-advisory  contract,  the Trust must call
and  hold a  shareholder  meeting  of the  Fund,  create  and  distribute  proxy
materials,  and arrange for the  solicitation  of voting  instructions  from the
Contract Owners.  This process is time-intensive,  slow and costly.  These costs
are generally borne entirely by the Fund.  Without the delay inherent in holding
shareholder meetings,  the Board would be able to act more quickly and with less
expense to appoint a sub-adviser when the Board and Mitchell  Hutchins feel that
the  appointment  would  benefit  the Fund and its  shareholders  (and  Contract
Owners).

      Also,  the Board  believes that it is  appropriate  to vest the selection,
supervision and evaluation of the sub-advisers in Mitchell  Hutchins (subject to
review by the Board) in light of Mitchell Hutchins'  significant  experience and


                                      -12-
<PAGE>


expertise in selecting sub-advisers and shareholders'  expectation that Mitchell
Hutchins will utilize that expertise to select the most competent  sub-advisers.
Mitchell  Hutchins  has  demonstrated  that it has the  requisite  expertise  to
evaluate,  select  and  supervise  sub-advisers.  The Board  believes  that many
investors choose to invest in the Fund because of Mitchell Hutchins'  experience
in this respect.

      Finally,  the Board will provide  sufficient  oversight of the sub-adviser
selection  process to ensure that  shareholders'  and Contract Owners' interests
are protected  whenever  Mitchell  Hutchins  selects a sub-adviser or modifies a
sub-advisory  contract.  The  Board,  including  a majority  of the  Independent
Trustees,  will continue to evaluate and approve all new sub-advisory  contracts
as well as any modification to existing sub-advisory  contracts. In each review,
the Board will  analyze  all  factors  that it  considers  to be relevant to the
determination,  including the nature,  quality and scope of services provided by
the  sub-advisers.  The Board will  compare the  investment  performance  of the
assets managed by the  sub-adviser  with other accounts with similar  investment
objectives   managed  by  other  advisers  and  will  review  the  sub-adviser's
compliance with federal securities laws and regulations. The Board believes that
its review will  ensure  that  Mitchell  Hutchins  continues  to act in the best
interests  of  the  Fund  and  its  shareholders  (and  Contract  Owners).   The
Sub-Advisory  Contract will continue to be subject to all provisions of the 1940
Act for which relief was granted by the SEC.

      REQUIRED VOTE. Approval of Proposal II requires the vote of a "majority of
the  outstanding  voting  securities"  of the Fund,  as defined in the 1940 Act,
which means the vote of 67% or more of the voting securities of the Fund present
at the Meeting, if the holders of more than 50% of the outstanding Shares of the
Fund are present or  represented  by proxy,  or the vote of more than 50% of the
outstanding voting securities of the Fund, whichever is less.

                    THE BOARD RECOMMENDS THAT CONTRACT OWNERS
                             VOTE "FOR" PROPOSAL II.

III.  OTHER BUSINESS

      Management  does not know of any  matters to be  presented  at the Meeting
other than those set forth in this proxy  statement.  If other  business  should
properly  come before the Meeting,  the proxies will vote thereon in  accordance
with their best judgment in the interests of the Fund.


                               PROXY SOLICITATION

      PROXY  SOLICITATION.  The  costs of the  Meeting,  including  the costs of
preparing solicitation materials, will be borne by PIMCO Advisors and Allianz of
America.  The principal  solicitation  will be by mail,  but proxies also may be
solicited by telephone, telegraph, the Internet or personal interview by regular
employees of PaineWebber Incorporated ("PaineWebber") and Mitchell Hutchins, who
will not receive any  compensation  from the Fund for doing so. MIS  Corporation

                                   ----------


                         FORM OF SUB-ADVISORY AGREEMENT
                         ------------------------------


        Contract made as of  __________,  2000 between  MITCHELL  HUTCHINS ASSET
MANAGEMENT  INC.  ("Mitchell  Hutchins"),  a Delaware  corporation,  and PACIFIC
INVESTMENT  MANAGEMENT COMPANY  ("Sub-Adviser"),  a Delaware general partnership
(hereinafter referred to as the "Contract").

                                    RECITALS

        (1)  Mitchell  Hutchins  has entered  into an  Investment  Advisory  and
Administration  Contract dated April 21, 1988, as  supplemented by an Investment
Advisory  and  Administration  Fee  Agreement  dated  May  1,  1989,  ("Advisory
Contract")  with Mitchell  Hutchins  Series Trust  (formerly  named  PaineWebber
Series Trust) ("Trust"),  an open-end  management  investment company registered
under the Investment Company Act of 1940, as amended ("1940 Act");

        (2) The  Trust  offers  for  public  sale  distinct  series of shares of
beneficial  interest,  including  a  series  of  shares  of the  Trust  known as
Strategic  Fixed  Income  Portfolio  (formerly  named  Government   Portfolio)
("Portfolio");

        (3) Under the Advisory Contract, Mitchell Hutchins has agreed to provide
certain investment advisory and administrative services to the Portfolio;

        (4) The Advisory  Contract permits Mitchell Hutchins to delegate certain
of its duties as investment adviser thereunder to a sub-adviser;

        (5)  Mitchell  Hutchins  wishes to retain  the  Sub-Adviser  to  furnish
certain investment advisory services to Mitchell Hutchins and the Portfolio; and

        (6) The Sub-Adviser is willing to furnish those services;

        NOW,  THEREFORE,  in  consideration of the premises and mutual covenants
herein contained, Mitchell Hutchins and the Sub-Adviser agree as follows:

      1.  APPOINTMENT.  Mitchell  Hutchins hereby appoints the Sub-Adviser as an
investment  sub-adviser  with respect to the Portfolio for the period and on the
terms set forth in this Contract.  The Sub-Adviser  accepts such appointment and
agrees to render the  services  herein set forth,  for the  compensation  herein
provided.

      2.    DUTIES AS SUB-ADVISER.

      (a) Subject to the  supervision  and  direction  of the  Trust's  Board of
Trustees ("Board") and review by Mitchell  Hutchins,  and any written guidelines
adopted  by the Board or  Mitchell  Hutchins,  the  Sub-Adviser  will  provide a


                                      A-1
<PAGE>


continuous  investment program for the Portfolio,  including investment research
and management.  The Sub-Adviser may from time to time seek research  assistance
and may rely upon resources available to it through its affiliated  companies to
the extent such actions would not constitute an "assignment" for purposes of the
1940 Act but in no case  shall  such  assistance  and/or  reliance  relieve  the
Sub-Adviser  of any of its  obligations  hereunder,  nor shall the  Portfolio or
Mitchell  Hutchins be responsible for any additional fees or expenses  hereunder
as a result.  The Sub-Adviser  will determine from time to time what investments
will be purchased,  retained or sold by the Portfolio.  The Sub-Adviser  will be
responsible  for placing  purchase and sell orders for investments and for other
related transactions.  The Sub-Adviser will be responsible for voting proxies of
issuers of securities held by the Portfolio.  The Sub-Adviser  understands  that
the  Portfolio's  assets  need to be managed so as to permit  the  Portfolio  to
qualify or to  continue  to  qualify as a  regulated  investment  company  under
Subchapter M of the Internal Revenue Code, as amended ("Code").  The Sub-Adviser
will provide  services  under this Contract in accordance  with the  Portfolio's
investment  objective,  policies and  restrictions  as stated in the Portfolio's
Prospectus and in the Trust's currently effective  registration  statement under
the  1940  Act,  and  any  amendments  or  supplements  thereto   ("Registration
Statement").

        (b) The Sub-Adviser agrees that, in placing orders with brokers, it will
obtain the best net result in terms of price and  execution;  provided  that, on
behalf of the Portfolio, the Sub-Adviser may, in its discretion, use brokers who
provide the Sub-Adviser with research,  analysis, advice and similar services to
execute portfolio  transactions on behalf of the Portfolio,  and the Sub-Adviser
may pay to those brokers in return for brokerage and research  services a higher
commission  than may be charged by other brokers,  subject to the  Sub-Adviser's
determination  in good faith that such  commission is reasonable in terms either
of  the  particular   transaction  or  of  the  overall  responsibility  of  the
Sub-Adviser  to  the  Portfolio  and  its  other  clients  and  that  the  total
commissions paid by the Portfolio will be reasonable in relation to the benefits
to the Portfolio over the long term. In no instance will portfolio securities be
purchased  from  or  sold  to  Mitchell  Hutchins  or  the  Sub-Adviser,  or any
affiliated person thereof, except in accordance with the federal securities laws
and the rules and  regulations  thereunder.  The Sub-Adviser may aggregate sales
and  purchase  orders with respect to the assets of the  Portfolio  with similar
orders being made  simultaneously  for other accounts advised by the Sub-Adviser
or its  affiliates.  Whenever the  Sub-Adviser  simultaneously  places orders to
purchase or sell the same  security on behalf of the  Portfolio  and one or more
other accounts  advised by the  Sub-Adviser,  the orders will be allocated as to
price and amount  among all such  accounts in a manner  believed to be equitable
over time to each account.  Mitchell Hutchins recognizes that in some cases this
procedure may adversely affect the results obtained for the Portfolio.

      (c) The  Sub-Adviser  will  maintain all books and records  required to be
maintained  pursuant to the 1940 Act and the rules and  regulations  promulgated
thereunder  with  respect  to  actions  by  the  Sub-Adviser  on  behalf  of the
Portfolio,  and will furnish the Board and Mitchell  Hutchins with such periodic
and special reports as the Board or Mitchell Hutchins reasonably may request. In
compliance  with  the  requirements  of Rule  31a-3  under  the  1940  Act,  the
Sub-Adviser  hereby  agrees that all records that it maintains for the Portfolio
are the property of the Trust,  agrees to preserve for the periods prescribed by
Rule 31a-2 under the 1940 Act any records  that it  maintains  for the Trust and
that are required to be maintained by Rule 31a-1 under the 1940 Act, and further
agrees to surrender promptly to the Trust any records which it maintains for the


                                      A-2
<PAGE>


Portfolio upon request by the Trust.

      (d) At such  times  as  shall  be  reasonably  requested  by the  Board or
Mitchell Hutchins,  the Sub-Adviser will provide the Board and Mitchell Hutchins
with economic and investment  analyses and reports as well as quarterly  reports
setting forth the  Portfolio's  performance  and make available to the Board and
Mitchell  Hutchins any economic,  statistical  and investment  services that the
Sub-Adviser normally makes available to its institutional or other customers.

      (e) In accordance  with  procedures  adopted by the Board, as amended from
time to time, the Sub-Adviser is responsible for assisting in the fair valuation
of all portfolio  securities and will use its reasonable  efforts to arrange for
the provision of a price(s) from a party(ies) independent of the Sub-Adviser for
each  portfolio  security for which the custodian  does not obtain prices in the
ordinary course of business from an automated pricing service.

        3. FURTHER  DUTIES.  In all matters  relating to the performance of this
Contract, the Sub-Adviser will act in conformity with the Trust's Declaration of
Trust, By-Laws and Registration  Statement and with the written instructions and
written directions of the Board and Mitchell Hutchins;  and will comply with the
requirements  of the 1940  Act,  and the  Investment  Advisers  Act of 1940,  as
amended  ("Advisers Act") and the rules under each,  Subchapter M of the Code as
applicable to regulated investment companies, the diversifications  requirements
applicable  to the  Portfolio  under  Section  817(h)  of the Code and all other
federal  and  state  laws  and  regulations  applicable  to the  Trust  and  the
Portfolio.  Mitchell Hutchins agrees to provide to the Sub-Adviser copies of the
Trust's  Declaration  of  Trust,  By-Laws,   Registration   Statement,   written
instructions  and  directions  of the  Board  and  Mitchell  Hutchins,  and  any
amendments or supplements to any of these materials as soon as practicable after
such materials become available;  provided however that the  Sub-Adviser's  duty
under this Contract to act in  conformity  with any  document,  instruction,  or
guidelines  produced by the Trust or Mitchell  Hutchins shall not arise until it
has been delivered to the Sub-Adviser.  Any changes to the objectives,  policies
or  restrictions  will  make  due  allowance  for  the  time  within  which  the
Sub-Adviser shall have to come into compliance.

      4.   EXPENSES.  During  the term  of this  Contract,  the Sub-Adviser will
bear all expenses  incurred by it in  connection  with its  services  under this
Contract.  The Sub-Adviser shall not be responsible for any expenses incurred by
the Trust, the Portfolio or Mitchell Hutchins.

      5.   COMPENSATION.

      (a)  For the services provided and the expenses assumed by the Sub-Adviser
pursuant to this Contract,  Mitchell Hutchins,  and not the Portfolio,  will pay
to the Sub-Adviser a fee, computed daily and payable monthly,  at an annual rate
of 0.25% of the  Portfolio's  average  daily net assets  (computed in the manner
specified in the Advisory  Contract),  and will provide the  Sub-Adviser  with a
schedule showing the manner in which the fee was computed.

      (b) The fee shall be accrued daily and payable  monthly to the Sub-Adviser
on or before the last business day of the next succeeding calendar month.


                                      A-3
<PAGE>


      (c) For those periods in which  Mitchell  Hutchins has agreed to waive all
or a portion of its management fee, Mitchell Hutchins may ask the Sub-Adviser to
waive  the  same  proportion  of its  fees,  but the  Sub-Adviser  is  under  no
obligation to do so.

      (d) If this Contract  becomes  effective or  terminates  before the end of
any month,  the fee for the  period  from the  effective  date to the end of the
month or from the  beginning  of such month to the date of  termination,  as the
case may be, shall be pro-rated  according  to the  proportion  that such period
bears to the full month in which such effectiveness or termination occurs.

        6. LIMITATION OF LIABILITY.  The Sub-Adviser shall not be liable for any
error of judgment or mistake of law or for any loss  suffered by the  Portfolio,
the Trust or its  shareholders  or by Mitchell  Hutchins in connection  with the
matters to which this  Contract  relates,  except a  loss resulting from willful
misfeasance, bad faith or gross negligence on its part in the performance of its
duties or from reckless disregard by it of its obligations and duties under this
Contract.   Nothing in this paragraph  shall be deemed a limitation or waiver of
any obligation or duty that may not by law be limited or waived.

      7. REPRESENTATIONS OF SUB-ADVISER.  The Sub-Adviser  represents,  warrants
and agrees as follows:

      (a) The Sub-Adviser  (i) is registered as an investment  adviser under the

from performing the services contemplated by this Contract;  (iii)  has met, and
will  seek to  continue to meet for so long as this  Contract remains in effect,

requirements of any regulatory or industry  self-regulatory agency, necessary to
be met in order to perform the services contemplated by this Contract;  (iv) has
the  authority  to enter into and  perform  the  services  contemplated  by this
Contract;  and (v) will  promptly notify Mitchell  Hutchins of the occurrence of
any event that would  disqualify the  Sub-Adviser  from serving as an investment
adviser of an  investment  company  pursuant to Section  9(a) of the 1940 Act or
otherwise.

      (b) The  Sub-Adviser  has adopted a written code of ethics  complying with
the  requirements  of Rule 17j-1  under the 1940 Act and will  provide  Mitchell
Hutchins  and the  Board  with a copy of such  code  of  ethics,  together  with
evidence of its  adoption.  Within  fifteen days of the end of the last calendar
quarter  of each  year that this  Contract  is in  effect,  the  president  or a
vice-president  of the Sub-Adviser  shall certify to Mitchell  Hutchins that the
Sub-Adviser has complied with the requirements of Rule 17j-1 during the previous
year and that there has been no violation of the Sub-  Adviser's  code of ethics
or, if such a  violation  has  occurred,  that  appropriate  action was taken in
response to such violation.  Upon the written request of Mitchell Hutchins,  the
Sub-Adviser  shall  permit  Mitchell  Hutchins,  its  employees or its agents to
examine the reports required to be made to the Sub-Adviser by Rule 17j-1 and all

annually.

      (d) The  Sub-Adviser  shall provide notice to Mitchell  Hutchins  within a
reasonable  time after being  informed or learning of the death or withdrawal of
any of its  partners,  upon the  admission of any new partners or upon any other
change in its membership.

      (e) The Sub-Adviser will notify Mitchell Hutchins of any change of control
of the  Sub-Adviser,  including  any  change  of  its  general  partners  or 25%
shareholders, as applicable, and any changes in the key personnel who are either
the  portfolio   manager(s)  of  the  Portfolio  or  senior  management  of  the
Sub-Adviser, in each case prior to, or promptly after, such change.

      (f) The  Sub-Adviser  agrees that  neither it, nor any of its  affiliates,
will in any way refer directly or indirectly to its relationship with the Trust,
the  Portfolio,  Mitchell  Hutchins  or any of their  respective  affiliates  in
offering,  marketing or other promotional  materials without the express written
consent of Mitchell Hutchins.

      8.  SERVICES  NOT  EXCLUSIVE.  The  Sub-Adviser  may act as an  investment
adviser to any other person, firm or corporation, and may perform management and

in connection  therewith or related thereto,  except as prohibited by applicable
law; and no such  performance  of management or other  services or taking of any
such  action or doing of any such  thing  shall be in any manner  restricted  or
otherwise  affected by any aspect of any  relationship  of the Sub-Adviser to or
with the Trust, Portfolio or Mitchell Hutchins or deemed to violate or give rise
to any duty or obligation of the Sub-Adviser to the Trust, Portfolio or Mitchell
Hutchins except as otherwise imposed by law or by this Contract.

      9.    DURATION AND TERMINATION.

      (a) This  Contract  shall  become  effective  upon the  date  first  above

the payment of any penalty,  by Mitchell  Hutchins:  (i) upon 120 days'  written

Trust who are not  parties to this  Contract or  interested  persons of any such
party,  and (ii) by a vote of a majority of the Portfolio's  outstanding  voting
securities  (unless  in the case of (ii),  the  Trust  receives  an SEC order or
no-action letter permitting it to modify the Contract without such vote).

      11.  GOVERNING LAW.  This Contract  shall be construed in accordance  with
