  This Proxy Statement is furnished in connection with the solicitation of
proxies by the board of trustees ("Board") of PaineWebber Series Trust
("Trust") for use at the special meeting of shareholders of the Global Growth
Portfolio ("Portfolio") to be held on June 8, 1995, or any adjournments thereof
("Meeting"). This Proxy Statement will first be mailed to shareholders on or
about May 15, 1995.
 
  The shares ("Shares") of the Portfolio are currently sold only to the
separate accounts ("Separate Accounts") of PaineWebber Life Insurance Company,
American Republic Insurance Company and American Benefit Life Insurance Company
(collectively, the Companies) to fund the benefits under variable annuity
contracts ("Contracts") issued by the Companies. In accordance with their view
of applicable law, the Companies will solicit voting instructions from the
owners of Contracts relating to the Portfolio ("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. The solicitation of proxies will be
made primarily by mail but also may include telephone or oral communications by
regular employees of the Companies, Mitchell Hutchins Asset Management Inc.
("Mitchell Hutchins") or PaineWebber Incorporated ("PaineWebber"), none of whom
will receive any compensation therefor from the Portfolio. The costs associated
with such solicitation and the Meeting will be borne by the Portfolio.
 
  Contract Owners at the close of business on April 24, 1995 (the "Record
Date") will be entitled to be present and give voting instructions for the
Portfolio at the Meeting, with respect to their Shares owned as of the Record
Date. There were 3,089,317 Shares of the Portfolio outstanding and entitled to
vote as such record date, representing total net assets of approximately
$35,434,469. All Shares of the Portfolio held by the Separate Accounts will be
voted by the Companies in accordance with voting instructions received from
Contract Owners. The Companies will vote Shares of the Portfolio for which no
instructions are received in the same proportion as Shares of the Portfolio for
which instructions have been received.
 
  To the knowledge of the Trust's management, as of the Record Date, no current
trustee of the Trust owned 1% or more of the outstanding Shares of the
Portfolio or any other series of the Trust. To the knowledge of the Trust's
management, as of the Record Date, the officers and trustees of the Trust
owned, as a group, less than 1% of the outstanding Shares of the Portfolio or
any other series of the Trust.
 
  On the Record Date, the Separate Accounts of PaineWebber Life Insurance
Company, American Republic Insurance Company and American Benefit Life
Insurance Company owned of record 51%, 47% and 2%, respectively, of the
outstanding Shares of the Portfolio. To the knowledge of the Trust's
management, as of the Record Date, there are no persons owning beneficially
more than 5% of the outstanding Shares of the Portfolio.
 
  Mitchell Hutchins currently serves as the Portfolio's administrator and
investment adviser. GE Investment Management Incorporated ("GEIM") serves as
investment sub-adviser ("Sub-Adviser") to the Portfolio. Mitchell Hutchins and
PaineWebber are located at 1285 Avenue of the Americas, New York, New York
10019. The Trust has no principal underwriter.

 
                                  PROPOSAL 1
 
        APPROVAL OR DISAPPROVAL OF THE PROPOSED SUB-ADVISORY AGREEMENT
 
BACKGROUND
 
  Mitchell Hutchins functions as the administrator and investment adviser of
the Portfolio pursuant to a contract with the Trust dated April 21, 1988
("Advisory Agreement"). The Advisory Agreement was approved by shareholders of
the Trust on April 21, 1988, and its continuance was most recently approved by
the Board of Trustees in May 1994. Under the Advisory Agreement, Mitchell
Hutchins receives a monthly fee at the annual rate of 0.75% of the Portfolio's
average daily net assets. For the fiscal year ended December 31, 1994, the
Portfolio paid fees under the Advisory Agreement to Mitchell Hutchins of
approximately $332,624.
 
  At a meeting held on March 22, 1995, the Board, including a majority of the
trustees who are not "interested persons" of the Trust, as defined in the
Investment Company Act of 1940 ("1940 Act") ("Independent Trustees"),
considered a recommendation by Mitchell Hutchins that GEIM be appointed as
investment sub-adviser for the Portfolio. After considering Mitchell Hutchins'
recommendation and other information, the Board approved an interim sub-
advisory agreement ("Interim Agreement") with GEIM, pursuant to which GEIM
currently acts as Sub-Adviser to the Portfolio. At that meeting, the Board
approved submission of the proposed sub-advisory agreement ("Sub-Advisory
Agreement") (which is substantially similar to the Interim Agreement) to the
Portfolio's shareholders at the Meeting, and determined to recommend that the
Portfolio's shareholders approve the proposed Sub-Advisory Agreement.
 
  Mitchell Hutchins' recommendation to the Board that GEIM be retained as Sub-
Adviser stemmed from a number of factors. First, in the months prior to the
Board meeting, Mitchell Hutchins had been engaged in an extensive review of
the long-term needs of its clients, and of its own structure and deployment of
resources. As a result of this review, Mitchell Hutchins determined to
concentrate its equity management resources on domestic equity securities and
to rely on independent management firms with extensive experience in global
and international securities for the day-to-day portfolio management of the
global equity funds managed by Mitchell Hutchins. During this same period,
Mitchell Hutchins became familiar with the abilities and expertise of GEIM.
GEIM serves as the sub-adviser for certain funds formerly advised by Kidder
Peabody Asset Management Inc. Mitchell Hutchins has been managing those funds
since February 13, 1995, in connection with an Asset Purchase Agreement among
Paine Webber Group Inc., Kidder, Peabody & Co. Inc. and General Electric
Company ("GE"). After consideration, Mitchell Hutchins determined that it
would be in the best interest of the Portfolio and certain other global equity
funds advised by Mitchell Hutchins to recommend to the boards of
trustees/directors (including the Board) that they approve sub-advisory
agreements with GEIM and authorize the submission of the sub-advisory
agreements to the shareholders of the global equity funds for approval.
 
  The Interim Agreement with respect to the Portfolio provides that GEIM,
subject to the supervision of Mitchell Hutchins and the Board, shall provide a
continuous investment program and strategy with respect to the investments of
the Portfolio, including investment research and
 
                                       2

 
management, and will make decisions with respect to and place orders for all
purchases and sales of portfolio securities. Under the Interim Agreement,
Mitchell Hutchins (not the Portfolio) pays GEIM a monthly fee for its
investment advisory services at an annual rate of 0.29% of the Portfolio's
average daily net assets. Because the Interim Agreement became effective on
March 23, 1995, during the Portfolio's current fiscal year, Mitchell Hutchins
paid no sub-advisory fees to GEIM during the 1994 fiscal year.
 
  GEIM also acts as the investment sub-adviser to the Mitchell Hutchins/Kidder,
Peabody Intermediate Fixed Income Fund, Mitchell Hutchins/Kidder, Peabody
Global Equity Fund (a series of Mitchell Hutchins/Kidder, Peabody Investment
Trust), and as investment adviser and administrator of the GE Funds and the
Variable Investment Trust, open-end management investment companies, each with
multiple investment portfolios, and as investment adviser to other accounts. In
addition, GEIM's principal officers and directors serve in similar capacities
with respect to General Electric Investment Corporation ("GEIC"), which, like
GEIM, is a wholly owned subsidiary of GE, and which currently serves as the
investment adviser to the Elfun group of funds and other GE pension and benefit
plan accounts. Since March 23, 1995, GEIM has served as investment sub-adviser
to the Fund, PaineWebber Europe Growth Fund and PaineWebber Global Growth and
Income Fund (each a series of PaineWebber Investment Series), PaineWebber Atlas
Global Growth Fund (the sole series of PaineWebber Atlas Fund), and Global
Small Cap Fund Inc. pursuant to interim agreements. The table below sets forth
certain information with respect to such investment portfolios that have
investment objectives similar to that of the Portfolio:

DESCRIPTION OF THE PROPOSED SUB-ADVISORY AGREEMENT
 
  The terms and conditions of the proposed Sub-Advisory Agreement provide for
the same sub-advisory fee as currently in effect for the Interim Agreement and
are otherwise substantially similar to those of the Interim Agreement except
for different effective and termination dates.
 
  If approved by the Shareholders at the Meeting, the Sub-Advisory Agreement
will remain in effect for two years after its effective date and thereafter
will continue from year to year, provided that such continuance is approved
annually (i) by the vote of a majority of the Independent Trustees and (ii) by
the Board or the vote of the holders of a majority of the outstanding Shares
of the Portfolio. The Sub-Advisory Agreement automatically terminates upon its
assignment and is terminable at any time without penalty, by the Board or by
the holders of a majority of the outstanding Shares of the Portfolio on 60
days' written notice. Either Mitchell Hutchins or GEIM may terminate the Sub-
Advisory Agreement on 120 days' written notice without penalty. Mitchell
Hutchins may also terminate the Sub-Advisory Agreement (i) upon material
breach by GEIM of certain of its representations under the Sub-Advisory
Agreement or (ii) in the event that GEIM is unable to discharge its duties
under the Sub-Advisory Agreement.
 
  Like the Interim Agreement, the Sub-Advisory Agreement provides that GEIM
will pay for all expenses incurred by it in connection with its investment
advisory services under the Sub-Advisory Agreement. The Sub-Advisory Agreement
also provides that GEIM, subject to the supervision of Mitchell Hutchins and
the Board, shall provide a continuous investment program and strategy for the
investments of the Portfolio, including investment research and management
with respect to all such securities and investments, and make decisions with
respect to and place orders for all purchases and sales of portfolio
securities. Under the Sub-Advisory Agreement, Mitchell Hutchins will pay to
GEIM a monthly fee of 0.29% of average daily net assets. This rate is the same
as that applied in the Interim Agreement.
 
  The Sub-Advisory Agreement provides that GEIM will not be liable for any
error of judgment or mistake of law or for any loss suffered by the Portfolio
in connection with the performance of the agreement, except a loss resulting
from willful misfeasance, bad faith, or gross negligence on the part of GEIM
in the performance of its duties or from reckless disregard of its obligations
and duties under the Sub-Advisory Agreement.
 
  GEIM makes various representations and warranties in the Sub-Advisory
Agreement, including (i) that it has adopted a written code of ethics which
complies with Rule 17j-1 under the 1940 Act and will certify its compliance
with such code of ethics to Mitchell Hutchins on an annual basis, and (ii)
that it is in compliance with various federal and state laws, including the
Investment Advisers Act of 1940 ("Advisers Act"), as amended.
 
  A copy of the proposed Sub-Advisory Agreement is attached to this Proxy
Statement as Exhibit A.

TRUSTEES' CONSIDERATIONS AND RECOMMENDATIONS
 
  At the meeting held on March 22, 1995, the Board, including the Independent
Trustees, after a full evaluation of the matters described above and with the
advice and assistance of counsel to the Independent Trustees, approved the
Interim Agreement and the proposed Sub-Advisory Agreement. During their
deliberations, the Trustees also reviewed information provided by Mitchell
Hutchins and GEIM relating to the structure and organization of GEIM. The Board
considered the quality of the investment sub-advisory services that had been
provided by GEIM to other funds, and also considered the Portfolio's
performance in relation to a selected group of other funds with similar
investment objectives. The Board noted, in particular, that the advisory fee
paid by the Portfolio would remain the same as before, and determined that the
terms of the Sub-Advisory Agreement and the sub-advisory fee were fair.
 
  The Board also considered the fact that consistent with the interests of the
Portfolio and subject to the review of the Board, the Sub-Adviser may cause the
Portfolio to purchase and sell portfolio securities through brokers who provide
the Sub-Adviser with research, analysis, advice and similar services. In return
for such services, the Portfolio may pay to those brokers a higher commission
than may be charged by other brokers, provided that the Sub-Adviser determines
in good faith that such commission is reasonable in terms either of that
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
 
                                       5

 
term. For purchases or sales with broker-dealer firms which act as principal,
the Sub-Adviser seeks best execution. Although the Sub-Adviser may receive
certain research or execution services in connection with these transactions,
the Sub-Adviser will not purchase securities at a higher price or sell
securities at a lower price than would otherwise be paid if no weight was
attributed to the services provided by the executing dealer. The Sub-Adviser
will not enter into any soft dollar arrangements relating to principal
transactions or receive in principal transactions the types of services which
could be purchased for hard dollars. Research services furnished by brokers
through which the Portfolio effects securities transactions may be used by the
Sub-Adviser in advising other funds or accounts it advises and, conversely,
research services furnished to the Sub-Adviser in connection with other funds
or accounts it advises may be used by the Sub-Adviser in advising the
Portfolio. Information and research received from brokers will be in addition
to, and not in lieu of, the services required to be performed by the Sub-
Adviser under the Sub-Advisory Agreement.
 
 VOTES REQUIRED FOR APPROVAL OF MATTERS AT THE MEETING
 
  At the Meeting, shareholders of the Portfolio will vote on the proposed Sub-
Advisory Agreement, in accordance with voting instructions received from the
Contract Owners. The Board of Trustees recommends that the shareholders approve
the Sub-Advisory Agreement. Approval of the Proposed Sub-Advisory Agreement by
the shareholders at the Meeting will also serve to ratify the Interim
Agreement. The affirmative vote of the holders of a majority of the outstanding
Shares of the Portfolio is required to approve the Sub-Advisory Agreement.
"Majority" for this purpose under the 1940 Act means the lesser of: (i) 67% of
the Shares of the Portfolio represented at the Meeting if the holders of more

                    FORM OF PROPOSED SUB-ADVISORY AGREEMENT
 
                             SUB-ADVISORY AGREEMENT
 
  Agreement made as of      ,1995, between MITCHELL HUTCHINS ASSET MANAGEMENT
INC. ("Mitchell Hutchins"), a Delaware corporation, and GE INVESTMENT
MANAGEMENT INCORPORATED ("Sub-Adviser"), a Delaware corporation (the
"Agreement").
 
                                    RECITALS
 
  (1) Mitchell Hutchins has entered into an Investment Advisory and
Administration Contract dated April 21, 1988, ("Management Agreement") with
PaineWebber Series Trust ("Trust"), an open-end management investment company
registered under the Investment Company Act of 1940, as amended ("1940 Act")
with respect to the Global Growth Portfolio ("Portfolio") series of the Trust;
and
 
  (2) Mitchell Hutchins wishes to retain the Sub-Adviser to furnish certain
investment advisory services to Mitchell Hutchins and the Portfolio, and the
Sub-Adviser is willing to furnish those services;
 
  NOW, THEREFORE, in consideration of the premises and mutual covenants herein
contained, the parties 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 Agreement. The Sub-Adviser accepts that 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 of and any guidelines adopted by the Trust's
Board of Trustees (the "Board"), the Sub-Adviser will provide a continuous
investment program for the Portfolio, including investment research and
management. 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 provide services under this
Agreement in accordance with the Portfolio's investment objective, policies and
restrictions as stated in the Portfolio's 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 Portfolio 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
 
                                      A-1

 
charged by other brokers, subject to the Sub-Adviser's determining 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 the Sub-Adviser, or any affiliated person thereof, except in accordance
with the federal securities laws and the rules and regulations thereunder.
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 by the Sub-Adviser 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 by the Sub-Adviser pursuant to the 1940 Act and the rules and
regulations promulgated thereunder with respect to transactions 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 which 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 which it maintains for
the Trust and which 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 Trust 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 normally
available to institutional or other customers of the Sub-Adviser.
 
  (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
any illiquid portfolio securities and will assist in providing independent
sources of market value for all other portfolio securities.
 
  3. Further Duties. In all matters relating to the performance of this
Agreement, the Sub-Adviser will act in conformity with the Trust's Trust
Instrument, By-Laws and currently effective registration statement under the
1940 Act and any amendments or supplements thereto ("Registration Statement")
and with the written instructions and directions of the Board and Mitchell
Hutchins and will comply with the requirements of the 1940 Act, the Investment
Advisers Act of 1940, as amended, ("Advisers Act"), the rules under each, and
Subchapter M of the Internal Revenue Code as applicable to regulated investment
companies. In addition, the Sub-Adviser will act in conformity with all other
applicable federal and state laws and regulations either as reflected in the
Registration Statement or otherwise provided in writing to the Sub-Adviser by
Mitchell Hutchins. Mitchell Hutchins agrees to provide to the Sub-Adviser
copies of the Trust's Trust Instrument, 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.
 
                                      A-2

 
  4.  Exclusivity. During the term of this Agreement, the Sub-Adviser agrees
that it will not provide investment advice on a discretionary or non-
discretionary basis for any global equity investment products offered to retail
customers in the United States by broker-dealers listed on Schedule A. The Sub-
Adviser shall deliver to Mitchell Hutchins in writing prompt and regular
reports of the Sub-Adviser's investment advisory activities in sufficient
detail to permit Mitchell Hutchins to monitor the terms of this Agreement.
 
  5. Expenses. During the term of this Agreement, the Sub-Adviser will bear all
expenses incurred by it in connection with its investment sub-advisory services
under this Agreement.
 
  6. Compensation.
 
  (a) For the services provided and the expenses assumed by the Sub-Adviser
pursuant to this Agreement, Mitchell Hutchins, not the Portfolio, will pay to
the Sub-Adviser a fee, computed daily and payable monthly, as computed in the
manner set forth in Schedule B, together with a schedule showing the manner in
which the fee was computed.
 
  (b) The fee shall be computed daily and payable monthly to the Sub-Adviser on
or before the fifteenth business day of the next succeeding calendar month.
 
  (c) If this Agreement 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 prorated according to the proportion which such period bears to
the full month in which such effectiveness or termination occurs.
 
  7. 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 Agreement 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 Agreement.
 
  8. Indemnification.
 
  (a) Mitchell Hutchins agrees to indemnify GEIM, its officers and directors,
and any person who controls GEIM within the meaning of Section 15 of the
Securities Act of 1933 ("1933 Act") for any loss or expense (including
attorneys' fees) arising out of any claim, demand, action or suit in the event
that GEIM has been found to be without fault and Mitchell Hutchins or its
parent company, PaineWebber Incorporated ("PaineWebber"), has been found at
fault (i) by the final judgment of a court of competent jurisdiction or (ii) in
any order of settlement of any claim, demand, action or suit that has been
approved by the Board of Directors of Mitchell Hutchins or PaineWebber.
 
  (b) GEIM agrees to indemnify Mitchell Hutchins, its officers and directors,
and any person who controls Mitchell Hutchins within the meaning of Section 15
of the 1933 Act for any loss or expense (including attorneys' fees) arising out
of any claim, demand, action or suit in the event that Mitchell Hutchins has
been found to be without fault and GEIM, or its parent company, General
Electric Company ("GE"), has been found at fault (i) by the final judgment of a
court of competent jurisdiction or (ii) in any order of settlement of any
claim, demand, action or suit that has been approved by the Board of Directors
of GEIM or GE.
