Dear Shareholder,
 
    On August 19, 1998, SunAmerica Inc. entered into an agreement with American
International Group, Inc. ("AIG"), the leading U.S.-based international
insurance organization. Under the terms of the agreement, AIG will acquire
SunAmerica Inc. and, consequently, SunAmerica Asset Management Corp. ("SAAMCo")
will become a part of AIG. SunAmerica will not change its name and no
organizational changes are planned which would effect services. As a result of
this transaction, it is necessary for the shareholders of SunAmerica Series
Trust (one of two underlying investment Trusts of your variable annuity), for
which SAAMCo acts as investment manager, to approve a new investment management
agreement.
 
    In addition, shareholders are also being asked to approve certain other
matters that have been set forth in the Notice of Special Meeting of
Shareholders. These include approving MASSACHUSETTS FINANCIAL SERVICES COMPANY
("MFS") AS THE REPLACEMENT SUBADVISER WITH RESPECT TO THE GROWTH/PHOENIX
INVESTMENT COUNSEL ("GROWTH PHOENIX") AND BALANCED/PHOENIX INVESTMENT COUNSEL
("BALANCED PHOENIX") PORTFOLIOS, as well as adjusting the fee arrangements with
respect to the Growth Phoenix, Balanced Phoenix and Alliance Growth Portfolios.
We have enclosed a Q&A to help you better understand matters relating to this
proxy vote.
 
    THE BOARD MEMBERS OF YOUR TRUST BELIEVE THAT EACH OF THE PROPOSALS SET FORTH
IN THIS NOTICE OF SPECIAL MEETING IS IMPORTANT AND RECOMMEND THAT YOU READ THE
ENCLOSED MATERIALS CAREFULLY AND THEN VOTE FOR ALL PROPOSALS.
 
    Since all of the Trusts which underlie SunAmerica life company variable
annuities are required to conduct shareholder meetings, you will receive more
than one proxy card if you are a shareholder in more than one Trust. IT IS VERY
IMPORTANT THAT YOU RESPOND TO ALL PROXY CARDS THAT YOU RECEIVE. In addition,
there are five ways to record your vote(s): Internet, touch-tone telephone, live
operator, fax or mail. Some of these options may not be available to all
shareholders. Please refer to the insert accompanying these proxy materials to
see which of these options you can use. If we do not receive a response by one
of these methods after a reasonable time, you may receive a call from our proxy
solicitor, Shareholder Communications Corporation, reminding you to vote your
shares.
 
    If you have questions regarding the proxy voting process, you may call
Shareholder Communications Corporation toll-free at 1-800-248-3249.
 
    YOUR VOTE IS IMPORTANT!
 
    We appreciate your cooperation and continued support.
 
                                          Sincerely,
 
                                                   [LOGO]

                            SUNAMERICA SERIES TRUST
                                 IMPORTANT NEWS
                    FOR SUNAMERICA SERIES TRUST SHAREHOLDERS
 
    While we encourage you to read the full text of the enclosed Proxy
Statement, here is a brief overview of some matters affecting your investment in
the Trust which require a shareholder vote. SunAmerica Series Trust is the
underlying investment in your variable annuity issued by Anchor National Life
Insurance Company and First SunAmerica Life Insurance Company.
 
                            Q & A: QUESTIONS AND ANSWERS
 
    Q.  WHAT IS HAPPENING?
 
    A.  SunAmerica Inc. ("SunAmerica"), the parent company of SunAmerica Asset
        Management Corp. ("SAAMCo"), your Trust's adviser, has agreed to merge
        with and into American International Group, Inc. ("AIG"). AIG is the
        leading U.S.-based international insurance organization. As a result of
        the proposed merger, there will be a change in ownership of SAAMCo. The
        following pages give you additional information on AIG, the proposed
        merger and the matters on which you are being asked to vote. THE BOARD
        MEMBERS OF YOUR TRUST, INCLUDING THOSE WHO ARE NOT AFFILIATED WITH THE
        TRUST, AIG, SAAMCO OR SUNAMERICA, UNANIMOUSLY RECOMMEND THAT YOU VOTE
        FOR THESE PROPOSALS.
 
    Q.  WHY DID YOU SEND ME THIS BOOKLET?
 
    A.  You are receiving these proxy materials--a booklet that includes the
        Proxy Statement and one or more voting instructions cards--because you
        have the right to provide voting instructions on the important proposals
        concerning your investment in the Trust.
 
    Q.  WHY ARE MULTIPLE CARDS ENCLOSED?
 
    A.  [If your investment is allocated among more than one Portfolio in your
        annuity contract, you will receive a voting instructions card for each
        Portfolio].
 
    Q.  WHY AM I BEING ASKED TO VOTE ON THE PROPOSED NEW ADVISORY AGREEMENT
        IN PROPOSAL NO. 2?
 
    A.  The Investment Company Act of 1940, which regulates investment companies
        such as your Trust, requires a vote whenever there is a change in
        control of an investment company's adviser. Upon a change of control,
        the advisory agreement between the investment adviser and the investment
        company terminates. SunAmerica's merger with AIG will result in a change
        of control of SAAMCo and therefore requires shareholder approval of a
        new advisory agreement between your Trust and SAAMCo. Each new advisory
        agreement that shareholders are being asked to vote on in Proposal No. 2
        is identical in all material respects to the existing advisory
        agreement.
 
    Q.  WHY AM I BEING ASKED TO VOTE ON THE PROPOSED NEW SUBADVISORY
        AGREEMENT IN PROPOSAL NO. 3?
 
    A.  Each subadvisory agreement provides that it terminates automatically if
        the advisory agreement with SAAMCo terminates. Because SunAmerica's
        merger with AIG will cause the termination of SAAMCo's advisory
        agreement, shareholder approval of the new subadvisory agreement is
        required. Each new subadvisory agreement that shareholders are being
        asked to vote on in Proposal No. 3 is identical in all material respects
        to the existing subadvisory agreement that it replaces.
<PAGE>
    Q.  WHAT ELSE AM I BEING ASKED TO VOTE ON?
 
    A.  You are being asked to elect a Board of Trustees. One consequence of the
        merger, as required by the Investment Company Act of 1940, is that the
        composition of your Board be changed so that at least 75% of the
        Trustees are not interested persons of the Trust. Currently, as required
        by the Investment Company Act, 40% of the Trustees are not interested
        persons. Also, in order to save the expense of a subsequent meeting, if
        your contract relates to an investment in the Alliance Growth, Growth/
        Phoenix Investment Counsel or Balanced/Phoenix Investment Counsel
        Portfolios, you are being asked to vote on certain changes to the
        advisory and subadvisory arrangements for each of those Portfolios.
        Changes to these three Portfolios are being proposed independent of the
        AIG-SunAmerica merger. In addition, you are being asked to vote to
        change certain of the fundamental investment restrictions of the Trust.
        Finally, you are being asked to vote to ratify the Board's selection of
        the Trust's independent accountants.
 
    Q.  HOW WILL THE AIG MERGER AFFECT ME?
 
    A.  The merger should have no impact on the operations of the Trust and its
        Portfolios. SAAMCo has assured the Trustees that there will be no
        reduction in the nature or quality of its services to the Trust as a
        result of the merger, and in fact anticipates that its resources may be
        enhanced.
 
    Q.  HOW DOES THE BOARD OF TRUSTEES RECOMMEND THAT I VOTE?
 
    A.  After careful consideration, the Board of your Trust, including those
        Trustees who are not affiliated with the Trust, AIG, SAAMCo or
        SunAmerica, recommend that you vote FOR all of the proposals on the
        enclosed voting instructions card.
 
    Q.  WHOM DO I CALL FOR MORE INFORMATION OR TO PLACE MY VOTE?
 
    A  You have several different ways to provide your Trust with your voting
       instructions. These ways include mail, speaking with a representative on
       the telephone, fax, touch-tone voting and voting on-line over the
       Internet. Not all of these options are available to all of you and you
       should refer to the insert accompanying this Q&A to see which of these
       options you can use. If you need more information on how to vote or if
       you have any questions, please call your Trust's information agent,
       Shareholder Communications Corporation, at 1-800-248-3249.
 
           YOUR VOTE IS IMPORTANT AND WILL HELP AVOID THE ADDITIONAL
                        EXPENSE OF ANOTHER SOLICITATION.
     THANK YOU FOR RESPONDING TO YOUR VOTING INSTRUCTIONS CARD(S) PROMPTLY.

    The Trust expects that the solicitation of voting instructions from contract
owners will be made by mail, and solicitation also may be made by telephone
communications from officers or employees of SAAMCo, the Life Companies, or
their affiliates, who will not receive any compensation therefor from the Trust.
In addition, Shareholder Communications Corporation ("SCC"), a professional
proxy solicitation firm, has been engaged to assist in the solicitation of
voting instructions. None of the costs of the solicitation will be borne by the
Trust or the Portfolios. In connection with the solicitation of voting
instructions, the Life Companies will furnish a copy of this Proxy Statement to
all contract owners.
 
    Contract owners may also provide their voting instructions through telephone
touch-tone voting or Internet voting. These options require contract owners to
input a twelve digit control number which is located on each voting instructions
card. Subsequent to inputting these numbers, contract owners will be prompted to
provide their voting instructions on each proposal. Contract owners will have an
opportunity to review their voting instructions and make any necessary changes
before submitting their voting instructions and terminating their telephone call
or Internet link. Contract owners who vote on the Internet, in addition to
confirming their voting instructions prior to submission, will also receive an
e-mail confirming their voting instructions.
 
    As the Meeting date approaches, certain contract owners may receive a
telephone call from a representative of SCC if their voting instructions have
not yet been received. Authorization to permit SCC to execute voting
instructions may be obtained by telephonically transmitted instructions from
contract holders. Voting instructions that are obtained telephonically will be
recorded in accordance with the procedures set forth below. The Trustees believe
that these procedures are reasonably designed to ensure that the identity of the
contract owner providing the voting instruction is accurately determined and
that the voting instructions of the contract owner are accurately determined.
The cost of this assistance is expected to be approximately $145,000 and, as
stated above, will not be borne by the Trust or the Portfolios.
 
    In all cases where telephonic voting instructions are solicited, the SCC
representative is required to ask for each contract owner's full name, address,
social security or taxpayer identification number, title (if the contract owner
is authorized to act on behalf of an entity, such as a corporation), and the
portion of shares beneficially owned and to confirm that the contract owner has
received the Proxy Statement and voting instructions card in the mail. If the
information solicited agrees with the information provided to SCC, then the SCC
representative has the responsibility to explain the process, read the proposals
listed on the voting instructions card, and ask for the contract owner's
instructions on each proposal. The SCC representative, although permited to
answer questions about the process, is not permitted to recommend to the
contract owner how to vote, other than to read any recommendation set forth in
the Proxy Statement. The SCC representative will record the contract owner's
instructions on the card. Within 72 hours, SCC will send the contract owner a
letter or mailgram to confirm his or her voting instructions and ask the
contract owner to call 1-800-248-3249 immediately if his or her instructions are
not correctly reflected in the confirmation.
 
    If the contract holder wishes to participate in the Meeting, but does not
wish to give his or her proxy by telephone communication with SCC, telephone
touch-tone voting or Internet voting, the contract owner may still submit the
voting instructions card originally sent with the Proxy Statement or attend in
person. Should contract owners require additional information regarding the
Proxy Statement or replacement voting instructions cards, they may contact SCC
toll-free at 1-800-248-3249. Voting instructions executed by contract owners may
be revoked by (i) a written instrument received by the Secretary of the Trust at
any time before they are exercised; (ii) delivery of a later-dated proxy; or
(iii) attendance at the Meeting and voting in person.

    [There were no persons who, as of the Record Date, were known to the Trust
to have allocated contributions under annuity contracts beneficially owned by
such person, such that, upon the pass through of voting rights by the Life
Companies, they would have the right to give voting instructions with respect to
more than 5% of the outstanding shares of the Trust or any Portfolio.] [CONFIRM]
To the knowledge of management, the Trustees and executive officers of the
Trust, both individually and as a group, owned less than 1% of the outstanding
shares of the Trust and each respective Portfolio as of the Record Date.
 
    The Life Companies, the holders of record shares of each Portfolio, are
required to "pass through" to their contract owners the right to vote shares of
each Portfolio. The Trust expects that the Life Companies will vote 100% of the
shares of the Portfolios held by their respective separate accounts. The Life
Companies will vote shares of the Portfolios for which no instructions have been
received in the same proportion as they vote shares for which they have received
instructions. Abstentions will have the effect of a negative vote on Proposal
Nos. 2, 3, 4, 5 or 6. Unmarked voting instructions from contract owners will be
voted in favor of the proposals. The Life Companies, as record shareholders of
each of the Portfolios, may
 
                                       5
<PAGE>
adjourn the Meeting to the extent permitted by law, if necessary to obtain
additional voting instructions from contract owners. Neither the Trust nor the
Portfolios will bear the costs of preparing and distributing to contract owners
additional proxy materials, if required in connection with any adjournment.
 
    Approval of each proposal, except Proposals No. 1 and 7, with respect to
each applicable Portfolio, requires the affirmative vote of a majority of the
outstanding voting securities of that Portfolio. "Majority" for this purpose
means more than 50% of the outstanding shares of the Portfolio. Each such
proposal must be approved by shareholders of the respective Portfolio voting
separately. Approval of a Proposal with respect to one Portfolio is not
conditioned on approval by shareholders of any other Portfolio.
 
    For Proposal No. 1, the candidates receiving a majority of the votes cast at
the Meeting will be elected. Approval of Proposal No. 7 requires a majority of
the votes cast at the Meeting. Shareholders of all Portfolios of the Trust vote
together as a single class with respect to Proposal Nos. 1 and 7.
 
    All information in the Proxy Statement about the current and proposed
subadvisers to the Portfolios (each, a "Subadviser" and collectively, the
"Subadvisers") has been provided by each respective Subadviser. All information
in the Proxy Statement about SAAMCo and the Life Companies has been provided by
SAAMCo and the Life Companies, respectively. All information in the Proxy
Statement about American International Group, Inc. ("AIG") has been provided by
AIG.
 
    The Trustees do not know of any other business to be brought before the
Meeting. If any other matters properly come before the Meeting, the proxies
named by the shareholders will vote on such matters in their discretion.

                                 PROPOSAL NO. 1
 
INTRODUCTION
 
    On August 19, 1998, SunAmerica Inc. ("SunAmerica") and AIG entered into an
Agreement and Plan of Merger (the "Merger Agreement") pursuant to which
SunAmerica will merge with and into AIG (the "Merger") with AIG as the
corporation surviving the Merger. Under the terms of the Merger Agreement, each
share of common stock, $1.00 par value per share, of SunAmerica outstanding at
the effective time of the Merger will be converted into 0.855 shares of common
stock, $2.50 par value per share, of AIG. SunAmerica and AIG expect that the
closing of the Merger (the "Closing") will take place during either the last
quarter of 1998 or the first quarter of 1999.
 
    The Merger is subject to certain regulatory approvals and other customary
conditions as well as to the approval of the Merger by the stockholders of
SunAmerica and AIG. Shareholders of the Trust are not being asked to vote on the
Merger of SunAmerica and AIG.
 
SECTION 15(f) OF THE 1940 ACT
 
    Section 15(f) of the 1940 Act provides that an investment adviser (such as
SAAMCo) to a registered investment company, and the affiliates of such adviser,
may receive any amount or benefit in connection with a sale of any interest in
such investment adviser which results in an assignment of an investment advisory
contract if the following two conditions are satisfied: (1) for a period of
three years after such assignment, at least 75% of the board of directors of the
investment company cannot be "interested persons" (within the meaning of Section
2(a)(19) of the 1940 Act) of the new investment adviser or its predecessor; and
(2) no "unfair burden" (as defined in the 1940 Act) may be imposed on the
investment company as a result of the assignment or any express or implied
terms, conditions or understandings applicable thereto.
 
    Consistent with the first condition of Section 15(f), SunAmerica and AIG
have agreed in the Merger Agreement that, for a period of three years after the
Closing, they will not take or recommend any action that would cause more than
25% of the Trustees of the Trust to be interested persons of the entity acting
as the Trust's investment adviser.
 
    With respect to the second condition of Section 15(f), an unfair burden on
an investment company is defined in the 1940 Act to include any arrangement
during the two-year period after any such transaction occurs whereby the
investment adviser or its predecessor or successor, or any interested person of
such adviser, predecessor or successor, receives or is entitled to receive any
compensation of two types, either directly or indirectly. The first type is
compensation from any person in connection with the purchase or sale of
securities or other property to, from or on behalf of the investment company,
other than bona fide ordinary compensation as principal underwriter for such
company. The second type is compensation from the investment company or its
security holders for other than bona fide investment advisory or other services.
 
    In the Merger Agreement, SunAmerica and AIG have agreed not to take or
recommend any action that would constitute an unfair burden on the Trust or the
Portfolios within the meaning of Section 15(f).
 
INFORMATION REGARDING NOMINEES
 
    At a meeting held on October 15, 1998, the Trustees, including all of those
Trustees who are not interested persons of SunAmerica, AIG or any Subadviser
(the "Disinterested Trustees"), unanimously nominated the 4 persons described
below for election as Trustees, to take office effective upon their election.
Three of the nominees are currently Trustees of the Trust. The Board of Trustees
currently consists of five members, two of whom will resign effective upon the
election of the nominees listed in this
 
                                       7
<PAGE>
Proxy Statement, to ensure that at least 75% of the Board will consist of
Trustees who are not interested persons of SunAmerica, AIG or any Subadviser. If
elected, each will serve until his or her successor is duly elected and
qualified. It is the intention of the persons named in the accompanying form of
proxy to vote for the election of each of the nominees named below, each of whom
has consented to be a nominee.
 
    If any of the nominees become unavailable for election as a Trustee before
the meeting, proxies will be voted for the other persons that the Trustees
recommend.
 
    Biographical data concerning all nominees is listed below.
 
    PRINCIPAL OCCUPATION AND OTHER INFORMATION
 
    The nominee designated by an asterisk (*), James K. Hunt, is an "interested
person," as that term is defined in the 1940 Act, of the Trust and of the
Adviser because Mr. Hunt is an officer of affiliates of the Adviser.

                                 PROPOSAL NO. 2
 
    The Board of Trustees of the Trust is submitting for approval by the
shareholders of each Portfolio, a new investment advisory and management
agreement (each, a "New Advisory Agreement" and together, the "New Advisory
Agreements") between the Trust, on behalf of each applicable Portfolio, and
SAAMCo, the terms of which are identical in all material respects to the current
investment advisory and management agreement with respect to each applicable
Portfolio (each an "Existing Advisory Agreement" and together, the "Existing
Advisory Agreements"). This Proposal does not, however, relate to the Growth
Phoenix and Balanced Phoenix Portfolios, which are discussed separately in
Proposal No. 5.
 
    As required by the 1940 Act, each Existing Advisory Agreement provides for
automatic termination upon assignment. The Closing of the Merger will constitute
an assignment, as that term is defined in the 1940 Act, of the Existing Advisory
Agreements, and, consequently, their termination. Accordingly, New Advisory
Agreements with SAAMCo to take effect upon the Closing are being proposed for
approval by the shareholders of each applicable Portfolio, even though those
agreements will be identical in all material respects to, and essentially a
continuation of, the Existing Advisory Agreements with SAAMCo. (The Existing
Advisory Agreements and New Advisory Agreements are sometimes collectively
referred to as the "Advisory Agreements.")
 
    In addition, each of the current subadvisory agreements (each, an "Existing
Subadvisory Agreement" and together, the "Existing Subadvisory Agreements")
between SAAMCo and the respective Subadviser to each Portfolio provides for
termination upon termination of the Existing Advisory Agreement. Accordingly,
each of the Existing Subadvisory Agreements will also terminate upon the Closing
of the Merger.
 
                                       11
<PAGE>
New Subadvisory Agreements are therefore also being separately proposed for
approval by shareholders and are described in Proposal No. 3.
 
    Although it is anticipated that the Closing will take place subsequent to
the shareholders' consideration and vote upon this Proposal No. 2 regarding New
Advisory Agreements, Proposal No. 3 regarding New Subadvisory Agreements, and
Proposal No. 5 relating to the Phoenix Growth and Phoenix Balanced Portfolios
(to the extent described in such proposal), it is possible that due to
unforeseen delays in the holding of the Meeting, the Closing will occur first.
If the Closing were to occur prior to the shareholders' vote upon such
Proposals, there would technically be a termination of the Existing Advisory and
Subadvisory Agreements (collectively, the "Existing Agreements"). To ensure the
uninterrupted receipt by the Portfolios of investment advice and management
services, SAAMCo and the Trust have applied for an exemptive order (the
"Exemptive Order") from the Securities and Exchange Commission (the "SEC") that
would allow SAAMCo and the current Subadvisers to continue to provide services
to the Portfolios, with the advisory and subadvisory fees being paid into escrow
during the period between the termination of the Existing Agreements and
shareholder approval of the New Agreements. The fees will be released from
escrow and paid to SAAMCo and the Subadvisers, respectively, only if the
shareholders approve, respectively, Proposal Nos. 2, 3 and 5. There can be no
assurance that the SEC will grant the requested Exemptive Order.
 
    Shareholders of Alliance Growth are also being asked, in addition, to
approve certain changes to its advisory and subadvisory arrangements. These
changes are described in Proposal No. 4 and are not related to the Merger
between SunAmerica and AIG.
 
APPROVAL OF THE NEW ADVISORY AGREEMENTS
 
    As described below, the Trustees are proposing that shareholders of each
Portfolio approve a New Advisory Agreement with SAAMCo and, as described in
Proposal No. 3, in connection therewith, new subadvisory agreements between
SAAMCo and each Subadviser (each a "New Subadvisory Agreement," together the
"New Subadvisory Agreements" and together with the New Advisory Agreements, the
"New Agreements"), to become effective as of the Closing. A description of the
New Advisory Agreements and the services to be provided by SAAMCo is set forth
below. This description is qualified in its entirety by reference to the form of
the New Advisory Agreement attached to this Proxy Statement as Exhibit A.
 
    As more fully described below, the proposed New Advisory Agreements,
including advisory fees, are identical in all material respects to the Existing
Advisory Agreements. The New Advisory Agreements differ from the Existing
Advisory Agreements only with respect to the effective dates.
 
    At a meeting held on October 15, 1998, the Trustees, including all of the
Disinterested Trustees, unanimously approved the New Agreements. In connection
with this approval, the Trustees considered that the terms of the Merger
Agreement do not contemplate any changes in the overall form of the advisory and
subadvisory contracts, the advisory fees, or any of the Portfolio's objectives
or policies. Among other things, the Trustees considered the fact that although
ultimate ownership of SAAMCo's parent company will change, senior officers of
SAAMCo had assured the Trustees that there would be no change in the personnel
providing services to the Trust and its applicable Portfolios and no diminution
in the nature or quality of those services. Senior officers of SAAMCo also
informed the Trustees that they did not foresee any changes in the day-to-day
operations of SAAMCo as a result of the Merger. As part of their deliberations,
the Trustees also took into account the following, among other factors: the
nature and quality of the services provided or reasonably anticipated to be
provided and the results achieved or reasonably anticipated to be achieved by
SAAMCo; the amount and structure of investment advisers' fees generally and the
fees payable under the New Agreements; and the organizational capability and
financial condition of SAAMCo and its affiliates.
 
    The Trustees also took into account the financial strength of AIG, the
management, personnel and operations of AIG, the commitment of AIG to the
financial services industry, and the proposed structure
 
                                       12
<PAGE>
of the Merger. The Trustees based their determinations in this regard on
discussions with representatives of AIG at the meeting and a review of materials
provided by AIG in connection with the meeting. The Trustees also considered the
additional resources that were likely to be available to SAAMCo following the
Closing.
 
RECOMMENDATION OF THE BOARD OF TRUSTEES
 
    Based on the considerations set forth above, the Trustees, including all of
the Disinterested Trustees, unanimously determined that it was necessary and in
the best interests of each applicable Portfolio and its shareholders to enter
into the New Advisory Agreements and to recommend approval of the New Advisory
Agreements by shareholders.

* For the period June 2, 1997 (commencement of operations) through November 30,
  1997.
 
               THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT
                     SHAREHOLDERS VOTE "FOR" PROPOSAL NO. 2
 
    If Proposal No. 2 is not approved by the shareholders of any Portfolio and
the Closing of the Merger is not effectuated, the Trustees will determine the
appropriate actions to be taken with respect to such Portfolio's advisory
arrangements at that time.
 
                            ------------------------
 
             APPROVAL OR DISAPPROVAL OF NEW SUBADVISORY AGREEMENTS
 
                                 PROPOSAL NO. 3
 
    The Board of Trustees of the Trust is submitting for approval by the
shareholders of Corporate Bond, Global Bond, Worldwide High Income, Asset
Allocation, Utility, Growth-Income, Federated Value, Venture Value, Alliance
Growth, Putnam Growth, Real Estate, International Growth and Income, Global
Equities, International Diversified Equities and Emerging Markets, a New
Subadvisory Agreement
 
                                       18
<PAGE>
between SAAMCo and each Subadviser, the terms of which are identical in all
material respects to each Existing Subadvisory Agreement.
 
    As described above in Proposal No. 2, each Existing Subadvisory Agreement
will terminate automatically upon termination of the Existing Advisory
Agreement. Accordingly, New Subadvisory Agreements between SAAMCo and each
Subadviser to take effect upon the Closing are being proposed for approval by
the shareholders of each applicable Portfolio, even though those agreements will
be identical in all material respects to, and essentially a continuation of, the
Existing Subadvisory Agreements between SAAMCo and the respective Subadviser.
(The Existing Subadvisory Agreements and the New Subadvisory Agreements are
hereinafter sometimes collectively referred to as the "Subadvisory Agreements.")
 
    New subadvisory agreements are being proposed for approval by shareholders
of Growth Phoenix and Balanced Phoenix. These new subadvisory agreements are
described in Proposal No. 5.
 
    Shareholders of Alliance Growth are also being asked, in addition, to
approve certain changes with respect to its advisory and subadvisory
arrangements. These changes are described in Proposal No. 4 and are not related
to the Merger between SunAmerica and AIG.
 
APPROVAL OF THE NEW SUBADVISORY AGREEMENTS
 
    As described below, the Trustees are proposing that shareholders of each
applicable Portfolio approve a New Subadvisory Agreement between SAAMCo and the
respective Portfolio's Subadviser, to become effective as of the Closing. A
description of the New Subadvisory Agreements and the services to be provided by
the Subadvisers is set forth below. This description is qualified in its
entirety by reference to the New Subadvisory Agreements attached to this Proxy
Statement as Exhibits C-1 - C-7.
 
    As more fully described below, the proposed New Subadvisory Agreements,
including subadvisory fees, are identical in all material respects to the
Existing Subadvisory Agreements. The New Subadvisory Agreements differ from the
Existing Subadvisory Agreements only with respect to the effective dates.
 
    At a meeting held on October 15, 1998, the Board of Trustees, including all
the Disinterested Trustees, unanimously approved the New Subadvisory Agreements.
In determining to approve the New Subadvisory Agreements, the Board of Trustees
evaluated the factors they deemed relevant with respect to each applicable
Portfolio, including the factors described in Proposal No.2 with respect to the
New Advisory Agreements. In addition, the Trustees considered the fact that the
terms of the Merger Agreement do not contemplate any changes in the overall form
of the subadvisory contracts or subadvisory fees and that the Merger will have
no effect with respect to the operations of any of the Subadvisers, since they
are independent of SAAMCo.
 
RECOMMENDATION OF THE BOARD OF TRUSTEES
 
    Based on the considerations set forth above, the Trustees, including all of
the Disinterested Trustees, unanimously determined that it was necessary and in
the best interests of each applicable Portfolio and its shareholders to enter
into the New Subadvisory Agreements and to recommend approval of the New
Subadvisory Agreements by shareholders.

INFORMATION ABOUT THE NEW SUBADVISORY AGREEMENTS
 
    As stated above, the New Subadvisory Agreements are annexed to this Proxy
Statement as Exhibits C-1 - C-7. Under each New Subadvisory Agreement, which is
identical in all material respects to each respective Portfolio's Existing
Subadvisory Agreement, the Subadviser will manage the investment and
reinvestment of the assets of the respective Portfolio for which it is
responsible, subject to the oversight and review of SAAMCo. The Subadviser will
determine in its discretion the securities to be purchased or sold, provide
SAAMCo with records concerning its activities which SAAMCo or the Trust is
required to maintain, and render regular reports to SAAMCo and to officers and
Trustees of the Trust concerning its discharge of the foregoing
responsibilities. Each Subadviser is independent of SAAMCo and will discharge
its responsibilities subject to the policies of the Trustees and the oversight
and supervision of SAAMCo, which pays the Subadvisers' fees.
 
    The following table sets forth the fees that the Adviser pays each
Subadviser under the Subadvisory Agreements on a monthly basis with respect to
each applicable Portfolio for which the Subadviser performs services, computed
on average daily net assets, at an annual rate, and the total subadvisory fees

paid to the Subadviser pursuant to the Existing Subadvisory Agreement for the
fiscal years ended November, 30, 1997.
 
    The rate of the subadvisory fees under the New Subadvisory Agreements is the
same rate that was in effect under the Existing Subadvisory Agreements.

* For the period 6/2/97 (commencement of operations) through 11/30/97.
 
    Under the terms of the Subadvisory Agreements, generally, the Subadvisers,
and their respective affiliated or controlling persons, will not be liable for
any acts or omissions connected with the services rendered under the respective
agreements, except where the act or omission results from willful misfeasance,
bad faith, gross negligence or reckless disregard of their duties and
obligations thereunder.
 
    If approved by the Shareholders, each New Subadvisory Agreement will
continue in effect for a period of two years from the Closing, and from year to
year thereafter as to each applicable Portfolio for so long as such renewal is
specifically approved at least annually by (i) the Board of Trustees, or by the
vote of a majority (as defined in the 1940 Act) of the outstanding voting
securities of each applicable Portfolio, and (ii) the vote of a majority of
Trustees who are not parties to the New Subadvisory Agreement or interested
persons (as defined in the 1940 Act) of any such party, cast in person, at a
meeting called for the purpose of voting on such approval. The New Subadvisory
Agreements provide that they will terminate in the event of an assignment (as
defined in the 1940 Act) or upon termination of the New Advisory Agreement of
the respective Portfolio. The New Subadvisory Agreements may be terminated by
the Trust, the Adviser or the respective Subadviser upon the specified written
notice contained in the Agreement.
 
    Certain information concerning the Existing Subadvisory Agreements,
including the date of the most recent approval by shareholders and Trustees, is
set forth in Exhibit K.

    If Proposal No. 3 is not approved by the shareholders of any applicable
Portfolio and the transactions contemplated by the Merger Agreement are
otherwise consummated, the Trustees will determine the appropriate actions to be
taken with respect to such applicable Portfolio's subadvisory arrangements at
that time.

                               THE TRUST AND THE
                ADVISER AND (b) AN AMENDMENT TO THE SUBADVISORY
                   AGREEMENT BETWEEN THE ADVISER AND ALLIANCE
                        (ALLIANCE GROWTH PORTFOLIO ONLY)
 
                                 PROPOSAL NO. 4
 
    The Board of Trustees of the Trust is submitting for approval by the
shareholders of the Alliance Growth Portfolio (a) an amendment to the investment
advisory and management agreement between the Trust, on behalf of the Alliance
Growth Portfolio, and the Adviser to revise the breakpoints in the fee payable
by the Portfolio (the "Alliance Fee Amendment"), and (b) an amendment to the
Subadvisory Agreement between the Adviser and Alliance (the "Alliance
Subadvisory Agreement") to revise the breakpoints in the fee payable by the
Adviser to Alliance (the "Alliance Subadvisory Fee Amendment" and together with
the Alliance Fee Amendment, the "Alliance Amendments"). A copy of the Alliance
Amendments are annexed as Exhibit L hereto. If approved by shareholders of the
Alliance Growth Portfolio, the Alliance Amendments will take effect as soon as
practicable thereafter. If the effective date of the Alliance Amendments occurs
prior to the Closing of the Merger, the Alliance Amendments will amend the
Existing Advisory and Subadvisory Agreements with respect to the Alliance Growth
Portfolio. Subject to approval of the New Advisory and Subadvisory Agreements by
Alliance Growth Portfolio shareholders in connection with the Merger, the
Alliance Amendments will also amend the New Agreements. The Alliance Amendments
are part of the same Proposal and will not be voted on separately by
shareholders of the Alliance Growth Portfolio.
 
    As part of SAAMCo's oversight responsibilities pursuant to the Advisory
Agreements, SAAMCo evaluates a Portfolio's performance in comparison to similar
mutual funds and other market information, and oversees the continued
performance of the Subadviser. At the October 15, 1998 Board meeting, the Board,
including the Disinterested Trustees, unanimously approved a subadvisory fee
increase for Alliance with respect to the Alliance Growth Portfolio, and a
corresponding increase in the advisory fee payable to SAAMCo so that the amount
of advisory fee retained by SAAMCo would not be reduced to fund the Alliance
increase. In determining to approve the Alliance Amendments, the Trustees
considered the historical performance record of the Alliance Growth Portfolio,
the rates generally charged by Alliance for its advisory services, the high
quality of investment subadvisory services rendered by Alliance, and the
importance of retaining a successful Subadviser. The Trustees also considered
that Alliance had requested such a fee increase and that the fee increase
reflects the rate agreed upon in arm's length bargaining between the Adviser and
Alliance. The Trustees also considered that the benefits of the increase will
inure solely to Alliance and not to SAAMCo.
 
RECOMMENDATION OF THE BOARD OF TRUSTEES
 
    Based upon the considerations set forth above, the Board of Trustees,
including all of the Disinterested Trustees, unanimously determined that it was
necessary and in the best interests of the Alliance

PROPOSED AND CURRENT ADVISORY AND SUBADVISORY FEES
 
    The following chart contains the proposed advisory fee to be payable by the
Alliance Growth Portfolio to the Adviser pursuant to the Alliance Fee Amendment
and the proposed subadvisory fee to be payable by the Adviser to Alliance
pursuant to the Alliance Subadvisory Fee Amendment. In addition, the chart
contains the fees payable under the investment advisory and management agreement
and the Alliance Subadvisory Agreement as currently in effect. Fees are
expressed as annual percentage rates of the average net assets of the Portfolio.
As can be seen, the maximum fee rate payable to the Adviser or Alliance pursuant
to the Alliance Amendments is not proposed to change. Rather, the proposed
changes are the elimination of the last two breakpoints in each fee.

    For the fiscal year ended November 30, 1997, the Alliance Growth Portfolio
paid SAAMCo an advisory fee of $3,145,937 (an effective annual fee rate of
 .59%), of which $1,280,957 was paid to Alliance (an effective annual fee rate of
 .24%). Had the rates pursuant to the Alliance Amendments been in effect during
the fiscal year ended November 30, 1997, the Alliance Growth Portfolio would
have paid SAAMCo an advisory fee of $3,297,109 (an effective annual fee rate of
 .62%), of which $1,432,129 would have been paid to the subadviser (an effective
annual fee rate of .27%). These amounts represent increases of $151,172 and
$151,172, or approximately 5% and 12%, respectively, over such fees actually
paid. The entire fee increase would have been paid to Alliance; accordingly, the
Adviser will not benefit from the change in fee rates.
 
    Alliance is described under Proposal No. 3 under "Information About the
Subadvisers--Alliance Capital Management, L.P." Alliance is the investment
adviser to other investment companies having a similar objective to the Alliance
Growth Portfolio as indicated in Exhibit D.
 
               THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT
                     SHAREHOLDERS VOTE "FOR" PROPOSAL NO. 4
 
    If this Proposal No. 4 is not approved, neither of the Alliance Amendments
will take effect.

          APPROVAL OR DISAPPROVAL OF (a) A NEW INVESTMENT ADVISORY AND
             MANAGEMENT AGREEMENT BETWEEN THE TRUST AND SAAMCO WITH
            RESPECT TO EACH OF GROWTH/PHOENIX INVESTMENT COUNSEL AND
          BALANCED/PHOENIX INVESTMENT COUNSEL PORTFOLIOS AND (b) A NEW
               SUBADVISORY AGREEMENT BETWEEN THE ADVISER AND MFS
 
                                 PROPOSAL NO. 5
 
    The Board of Trustees of the Trust is submitting for approval by the
shareholders of each of the Phoenix Growth and Phoenix Balanced Portfolios (a) a
new investment advisory and management agreement between the Trust, on behalf of
each respective Portfolio, and the Adviser ("New MFS Advisory Agreement") and
(b) a new subadvisory agreement between the Adviser and MFS (the "MFS
Subadvisory Agreement"). If this Proposal No. 5 is approved by shareholders, MFS
would serve as each Portfolio's Subadviser in place of Phoenix. The New MFS
Advisory Agreement is being submitted to shareholders for two reasons. First, as
discussed under Proposal No. 2, each Existing Advisory Agreement between SAAMCo
and the Trust, including the Existing Advisory Agreements relating to the
Phoenix Growth and Phoenix Balanced Portfolios, will terminate upon the Closing
of the Merger between SunAmerica and AIG. Thus, the New MFS Advisory Agreement
is being submitted for shareholder approval to ensure that the Portfolios
receive uninterrupted management and advisory services after the Closing.
Second, the New MFS Advisory Agreement is being submitted for shareholder
approval in order to revise the breakpoints in the advisory fee payable by the
applicable Portfolio pursuant to the Existing Advisory Agreement (the "Advisory
Fee Amendment"). The form of the New MFS Advisory Agreement (including the
Advisory Fee Amendment) is annexed as Exhibit A hereto. The form of MFS
Subadvisory Agreement for each Portfolio is annexed as Exhibit M hereto. If this
Proposal is approved by shareholders of a Portfolio, the Advisory
 
                                       31
<PAGE>
Fee Amendment and the MFS Subadvisory Agreement will take effect, for that
Portfolio, as of December 30, 1998 (the "MFS Effective Date"), and MFS will
become Subadviser as of such date in place of Phoenix, whether the MFS Effective
Date occurs prior to or after the Closing of the Merger. If the MFS Effective
Date is prior to the Closing, shareholder approval of this Proposal shall
constitute approval of the New MFS Advisory Agreement and the MFS Subadvisory
Agreement (the "MFS Agreements") both with respect to the period prior to the
Closing as well as following any deemed termination as a result of the Closing
of the Merger after their effective date.
 
    If the Closing of the Merger occurs prior to the MFS Effective Date and
shareholder approval of the MFS Agreements has not yet been obtained, subject to
receipt of the Exemptive Order described under Proposal No. 2, SAAMCo will
continue to provide management services to each of the Phoenix Growth and
Phoenix Balanced Portfolios, with its advisory fees being paid into escrow.
During such interim period, advisory fees would be payable at the rates
currently in effect under the Existing Advisory Agreement. In addition, SAAMCo
will enter into a subadvisory agreement with MFS that is substantially similar
in all material respects, other than the subadviser, to the Existing Subadvisory
Agreement between SAAMCo and Phoenix, including the same fee rate that is
currently in effect between SAAMCo and Phoenix (the "Interim Agreement").
Shareholder approval of this Proposal will be deemed to ratify the Interim
Agreement for the period from Closing until shareholder approval. As indicated
in Proposal No. 2, there can be no assurance that the SEC will grant the
Exemptive Order.
 
    The proposed MFS Agreements with respect to each Portfolio are part of the
same Proposal with respect to such Portfolio and will not be voted on separately
by shareholders of such Portfolio.
 
APPROVAL OF MFS AGREEMENTS
 
    At a meeting held on October 15, 1998, the Trustees, including all of the
Disinterested Trustees, unanimously approved the MFS Agreements. The Trustees
considered the factors described under Proposal No. 2--"Approval of the New
Advisory Agreements," as modified by factors specific to the Phoenix Growth and
Phoenix Balanced Portfolios and described in this section. The Trustees
considered that as part of SAAMCo's oversight responsibilities pursuant to the
Existing Advisory Agreement, SAAMCo, (i) evaluates each Portfolio's performance
in comparison to similar mutual funds and other market information, (ii)
conducts searches for a replacement Subadviser for each Portfolio when deemed
necessary, (iii) selects, subject to the review and approval of the Trustees, a
Subadviser that has distinguished itself by superior performance and (iv)
oversees the continued performance of the Subadviser. Recently, SAAMCo
determined, based in part on the performance of the Phoenix Growth and Phoenix
Balanced Portfolios in comparison to similar funds, that it was in the best
interest of the shareholders to replace the Subadviser for the Phoenix Growth
and Phoenix Balanced Portfolios. As a result of discussions with Phoenix, the
current Subadviser for each Portfolio, Phoenix has agreed to tender its
resignation as the Subadviser to the Phoenix Growth and Phoenix Balanced
Portfolios concurrent with MFS commencing its responsibilities as the successor
Subadviser.
 
    At the October 15, 1998 Board meeting, the Board, including all of the
Disinterested Trustees, unanimously approved the new MFS Subadvisory Agreements
pursuant to each of which MFS would serve as each Portfolio's Subadviser in
place of Phoenix. Except for an increase in the fees payable by the Adviser to
MFS thereunder as described below, the material terms of each MFS Subadvisory
Agreement are substantially similar to those of the respective Subadvisory
Agreement with Phoenix (each a "Phoenix Subadvisory Agreement"). The subadvisory
fees payable to MFS reflect the rate agreed upon in arm's length bargaining
between the Adviser and MFS. In addition, because of the higher fee payable by
the Adviser to MFS pursuant to each MFS Subadvisory Agreement, the Board,
including all of the Disinterested Trustees, unanimously approved amendments to
the investment advisory and management agreement between the Trust and the
Adviser pursuant to which the Adviser will receive increased fees payable by
each Portfolio to the Adviser. The Adviser, however, will not retain any of the
increase in fees; rather, all increases in fees will be directed to MFS.
 
                                       32
<PAGE>
    In selecting MFS as subadviser, the Trustees reviewed, among other things,
MFS's historical performance record in managing similar investment companies and
other client accounts, its name recognition in the investment community, its
financial condition, and its overall commitment to the investment advisory
business. MFS is America's oldest mutual fund organization and, with its
predecessor organizations, has a history of money management dating from 1924.
MFS is an indirect, wholly owned subsidiary of Sun Life Assurance Company of
Canada ("Sun Life"). As of August 31, 1998, MFS managed approximately $51.0
billion in assets in equity securities and $20.6 billion in assets in
fixed-income securities. The Trustees also took into account MFS's normal fee
schedule, and that the fee rate reflected in each of the MFS Subadvisory
Agreements reflects the rate agreed upon in arm's length bargaining between the
Adviser and MFS.
 
    The Trustees approved the Advisory Fee Amendments to minimize the reduction
in the amount of the advisory fee retained by the Adviser with respect to each
Portfolio. Under the original arrangement with Phoenix, for the fiscal year
ended November 30, 1997, SAAMCo retained a fee at the annual rate of .35% of
average net assets of each of the Phoenix Growth Portfolio and Phoenix Balanced
Portfolio. The Trustees considered that if the Adviser's rates were not adjusted
pursuant to each Advisory Fee Amendment, under the MFS Subadvisory Agreement, at
the current asset levels, the Adviser's advisory fee would be reduced to .24% of
average net assets in the case of the Phoenix Growth Portfolio and .295% of
average net assets in the case of the Phoenix Balanced Portfolio. Accordingly,
the Board approved each Advisory Fee Amendment to minimize the reduction in the
Adviser's advisory fee if MFS is retained as subadviser pursuant to the MFS
Subadvisory Agreements.
 
    At the meeting held on October 15, 1998, the Board also discussed the
Adviser's proposal that the investment objective of the Phoenix Growth Portfolio
be changed. The investment objective of the Portfolio is not a fundamental
policy and may be changed by vote of the Board of Trustees without shareholder
approval. The current investment objective of the Phoenix Growth Portfolio is
long-term growth of capital. On the recommendation of the Adviser, the Board
approved a change in the Portfolio's investment objective to reasonable current
income and long-term growth of capital and income. In conjunction with such
change in investment objective, the Board of Trustees approved a change in the
name of the Phoenix Growth Portfolio to the "MFS Conservative Growth Portfolio."
Representatives of SAAMCo informed the Board that MFS proposes to manage the
Phoenix Growth Portfolio in a manner similar to a retail mutual fund currently
managed by MFS. The Trustees considered the historical performance results of
that mutual fund, and believe that the change will benefit shareholders. Of
course, past performance is no assurance of future results.
 
    The Trustees at the October 15, 1998 meeting also approved a change in the
name of Phoenix Balanced Portfolio to "MFS Total Return Portfolio." The Board
did not change the investment objective of that Portfolio. Its investment
objective remains reasonable income, long-term capital growth and conservation
of capital.
 
    At the October 15, 1998 meeting, SAAMCo informed the Board that each of the
Life Companies had agreed that if MFS were approved as the new subadviser to the
Phoenix Growth and Phoenix Balanced Portfolios, contract holders that have
allocated all or a portion of their contract values to these Portfolios would be
entitled to one additional free transfer among Portfolios under their contracts.
 
RECOMMENDATION OF THE BOARD OF TRUSTEES
 
    Based upon the considerations set forth above, the Board of Trustees,
including all of the Disinterested Trustees, unanimously determined that it was
necessary and in the best interests of the Phoenix Growth and Phoenix Balanced
Portfolios and their respective shareholders to approve the MFS Agreements and
to recommend approval thereof by shareholders.

INFORMATION ABOUT MFS SUBADVISORY AGREEMENTS
 
    As stated above, the form of MFS Subadvisory Agreement is annexed to this
Proxy Statement as Exhibit M. Under the MFS Subadvisory Agreement, which is
substantially similar to the Phoenix Subadvisory Agreement, except for an
increase in the fees payable by SAAMCo to MFS as described below, MFS will
manage the investment and reinvestment of the assets of each of the Phoenix
Growth and Phoenix Balanced Portfolios, subject to the oversight and review of
SAAMCo. MFS will determine in its discretion the securities to be purchased or
sold, provide SAAMCo with records concerning its activities which SAAMCo or the
Trust is required to maintain, and render regular reports to SAAMCo and to
officers and Trustees of the Trust concerning its discharge of the foregoing
responsibilities. MFS is independent of SAAMCo and will discharge its
responsibilities subject to the policies of the Trustees and the oversight and
supervision of SAAMCo, which pays MFS fees.
 
    Under the terms of the MFS Subadvisory Agreement, MFS and its respective
affiliated or controlling persons, will not be liable for any acts or omissions
connected with the services rendered under the agreement, except where the act
or omission results from willful misfeasance, bad faith, gross negligence or
reckless disregard of its duties and obligations thereunder.
 
    If approved by the shareholders, the MFS Subadvisory Agreement will continue
in effect for a period of two years from the MFS Effective Date, and from year
to year thereafter as to each of Phoenix Growth and Phoenix Balanced for so long
as such renewal is specifically approved at least annually by (i) the Board of
Trustees, or by the vote of a majority (as defined in the 1940 Act) of the
outstanding voting securities of each applicable Portfolio, and (ii) the vote of
a majority of Trustees who are not parties to the MFS Subadvisory Agreement or
interested persons (as defined in the 1940 Act) of any such party, cast in
person, at a meeting called for the purpose of voting on such approval. The MFS
Subadvisory Agreement provides that it will terminate in the event of an
assignment (as defined in the 1940 Act) or upon termination of the New MFS
Advisory Agreement of the respective Portfolio. The New Subadvisory Agreement
may be terminated by the Trust, the Adviser or MFS upon the specified written
notice contained in the New Subadvisory Agreement.
 
PROPOSED AND CURRENT ADVISORY AND SUBADVISORY FEES
 
    Except with respect to the fees payable thereunder, the MFS Agreements are
substantially similar to the Existing Advisory and Subadvisory Agreements as
discussed in Proposal Nos. 2 and 3. The following charts contain the proposed
advisory fee to be payable by each Portfolio to the Adviser pursuant to the New
MFS Advisory Agreement and the proposed subadvisory fee to be payable by the
Adviser to MFS under each proposed MFS Subadvisory Agreement. In addition, the
chart contains the fees payable under the Existing Advisory Agreement and the
respective Phoenix Subadvisory Agreement as currently in effect. Fees are
expressed as annual percentage rates of the average net assets of each
Portfolio. As can be seen, the maximum fee rate payable to the Adviser by each
Portfolio pursuant to the Advisory Fee Amendment is not proposed to change. The
proposed changes in the Advisory Fee Amendment are in the breakpoints. The
subadvisory fee rate that will be payable to MFS is higher than that paid to
Phoenix.

    For the fiscal year ended November 30, 1997, the Phoenix Growth Portfolio
paid SAAMCo an advisory fee of $1,299,894 (an effective annual fee rate of
 .65%), of which $599,956 was paid to Phoenix (an effective annual fee rate of
 .30%). Had the rates pursuant to the Advisory Fee Amendment and the MFS
Subadvisory Agreement been in effect during the fiscal year ended November 30,
1997, the Phoenix Growth Portfolio would have paid SAAMCo an advisory fee of
$1,417,002 (an effective annual fee rate of .70%), of which $809,727 would have
been paid to the Subadviser (an effective annual fee rate of .40%). These
amounts represent increases of $117,128 and $208,771, or approximately 9% and
35%, respectively, over such fees actually paid. Thus, the fee retained by the
Adviser would have decreased under the new fee arrangement, with the full effect
of the proposed fee increase benefitting the Subadviser.

Had the rates pursuant to the Advisory Fee Amendment and the MFS Subadvisory
Agreement been in effect during the fiscal year ended November 30, 1997, the
Phoenix Balanced Portfolio would have paid SAAMCo an advisory fee of $558,675
(an effective annual fee rate of .68%), of which $307,890 would have been paid

represent increases of $0 and $36,578, or approximately 0% and 13.5%,
respectively, over
 
                                       36

such fees actually paid. Thus, the fee retained by the Adviser would have

         THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS

    If this Proposal No. 5 is not approved by shareholders of a Portfolio,
neither of the MFS Agreements will take effect with respect to that Portfolio
and the Trustees will determine the appropriate actions to be taken with respect

                             PROPOSAL CHANGING THE
                       FUNDAMENTAL INVESTMENT RESTRICTION
                  WITH RESPECT TO EACH PORTFOLIO'S ABILITY TO
                        ENGAGE IN BORROWING TRANSACTIONS
 
    The Board of Trustees of the Trust is submitting for approval by
shareholders of each Portfolio a proposal to amend the fundamental investment
restriction relating to borrowing transactions in order to permit each Portfolio
to borrow money from other mutual funds in the SunAmerica complex (the
"Affiliate Funds"), subject to receipt of appropriate exemptive relief from the
SEC. The Board of Trustees approved this proposal at a meeting held on October
15, 1998.
 
    For the reasons described below, the Board of Trustees recommends that
shareholders approve the proposed amendment. Fundamental investment restrictions
may be changed only with shareholder approval.
 
    If the proposed changes to the Portfolios' fundamental investment
restrictions are approved by shareholders at the Meeting, the Portfolios'
prospectus and statement of additional information will be revised as
appropriate to reflect the changes. This Proposal No. 6(a) will not result in a
change to the investment objective or operating procedure of any Portfolio.

    Upon approval of this Proposal, portions of the existing fundamental
investment restrictions of each Portfolio relating to borrowing transactions
will be replaced with the applicable portions of the proposed fundamental
investment restrictions, each as set forth above. Those portions of the existing
fundamental investment restrictions that are not described above will not be
affected by the adoption of this Proposal.
 
DISCUSSION
 
    The proposed change to each Portfolio's fundamental investment restriction
would allow each Portfolio to borrow from persons other than banks, to the
extent consistent with applicable law. The proposed changes are designed to
permit each Portfolio the greatest degree of flexibility permitted by law in
pursuing its investment program.
 
    Current law prohibits a Portfolio from borrowing other than from banks.
Accordingly, a Portfolio may not borrow from an Affiliate Fund. If the proposed
amendments to the Portfolios' fundamental investment restrictions on borrowing
are approved by shareholders, then the Trust, on behalf of the Portfolios, may
apply to the SEC for an exemption from this prohibition on interfund borrowing.
There is, of course, no assurance that the SEC would grant such request. If the
SEC did grant the request, each Portfolio would be allowed to borrow from other
Affiliate Funds. The Adviser and the Board of Trustees believe that the ability
to engage in borrowing transactions with participating Affiliate Funds as part
of a program, referred to as the "interfund lending program," may allow a
Portfolio to obtain lower interest rates on money borrowed for temporary or
emergency purposes.
 
    When a Portfolio is required to borrow money, under the 1940 Act it may do
so only from banks. When a Portfolio borrows money from banks, it typically pays
interest on those borrowings at a rate that is higher than rates available
contemporaneously from investments in repurchase agreements. If the proposed
amendments are approved (and an SEC exemptive order is granted), eligible
Affiliate Funds would be permitted to participate in an interfund lending
program to allow various Affiliate Funds, through a master loan agreement to
lend available cash to, and borrow from, other Affiliate Funds. Each lending
fund could lend available cash to another Affiliate Fund only when the interfund
rate was higher than repurchase agreement rates or rates on other comparable
short-term investments. Each borrowing fund could borrow through the interfund
lending program only when the interfund loan rate was lower than available bank
loan rates. Thus, each Affiliate Fund would participate in the interfund lending
program only when it would be in such fund's economic best interest to do so.
 
    In determining to recommend the proposed amendments to shareholders for
approval, the Adviser discussed with the Board of Trustees the possible risks to
a Portfolio of participating in the interfund lending program. The Adviser has
indicated that it does not view the difference in rates available on bank
borrowings and repurchase agreements or other short-term investments as
reflecting a material difference in the quality of the risk of the transactions,
but rather as an indication of the ability of banks to earn a higher rate of
interest on loans than they pay on repurchase agreements or other short-term
investments. There is a risk that a lending fund could experience a delay in
obtaining prompt repayment of a loan and, unlike repurchase agreements, the
lending fund would not necessarily have received collateral for its loan,
although it could require that collateral be provided as a condition for making
an interfund loan. A delay in obtaining prompt payment could cause a lending
fund to miss an investment opportunity or to incur costs to borrow money to
replace the delayed payment. There is also a risk that a borrowing fund could
have a loan recalled on one day's notice and the borrowing fund might then have
to borrow from a bank at a higher interest rate if money could not be borrowed
from another Affiliate Fund. A Portfolio will participate in the interfund
lending program only if the Board of Trustees considers that the benefits to the
Portfolio of participating in the program outweigh the possible risks of such
participation.
 
    As discussed above, in order to permit each Portfolio to engage in interfund
lending transactions, regulatory approval of the SEC is required because, among
other reasons, the transactions may be considered to be among affiliated
parties. If the proposed amendments are approved by shareholders, the
 
                                       38
<PAGE>
proposed interfund lending program would be implemented only to the extent
permitted by rule or by order of the SEC and to the extent that the transactions
were otherwise consistent with the investment objectives and limitations of each
participating Affiliate Fund. As previously noted, if exemptive relief from the
SEC is not granted, no Portfolio will be able to engage in the interfund lending
program even though shareholders have approved this proposal. No prediction can
be made as to whether the SEC would grant such relief.
 
    In this proposal, shareholders are being asked to approve an amendment to
each Portfolio's fundamental investment restriction on borrowing. Shareholders
are also being asked to vote separately on an amendment to each Portfolio's
fundamental investment restriction on lending (see Proposal No. 6(b)). If both
amendments are adopted, each Portfolio, subject to its investment objective and
policies, will be able to participate in the interfund lending program as both a
lender and a borrower. If only one of the two proposals is adopted, then such
Portfolio's participation in the interfund lending program will be confined to
either lending or borrowing, depending on which amendment is approved.
 
    The Board of Trustees believes the proposed amendments may benefit each
Portfolio by facilitating its flexibility to explore cost-effective alternatives
to satisfy its borrowing requirements by borrowing money from other Affiliate
Funds. Implementation of interfund borrowing would be accomplished consistent
with applicable regulatory requirements, including the provisions of any order
the SEC might issue to each Portfolio and to other Affiliate Funds.

                  PROPOSAL CHANGING THE FUNDAMENTAL INVESTMENT
                  RESTRICTION WITH RESPECT TO EACH PORTFOLIO'S
                   ABILITY TO ENGAGE IN LENDING TRANSACTIONS
 
    The Board of Trustees is submitting for approval by shareholders of each
Portfolio a proposal to amend the fundamental investment restriction relating to
lending transactions in order to permit each Portfolio to participate in
interfund lending transactions as described in Proposal No. 6(a). The Board of
Trustees approved this proposal at a meeting held on October 15, 1998.
 
    For the reasons described below, the Board of Trustees recommend that
shareholders approve the proposed amendment. Fundamental investment restrictions
may be changed only with shareholder approval.
 
    If the proposed changes to the Portfolios' fundamental investment
restrictions are approved by shareholders at the Meeting, the Portfolios'
prospectus and statement of additional information will be revised as
appropriate to reflect the changes. This Proposal No. 6(b) will not result in a
change to the investment objective or operating procedure of any Portfolio.

</TABLE>
 
    Upon approval of this Proposal, the existing fundamental investment
restriction of each Portfolio relating to lending transactions will be amended
by adding the bolded portions of the proposed fundamental investment
restrictions, as set forth above. No other portions of the existing fundamental
investment restrictions will be affected by the adoption of this Proposal.
 
DISCUSSION
 
    The proposed amendment to each Portfolio's fundamental investment
restriction would allow a Portfolio to participate in an interfund lending
program with other Affiliate Funds. The nature of this program and the risks
associated with each Portfolio's participation therein are set forth under
Proposal No. 6(a). Shareholders are being asked to consider, and vote
separately, on each Portfolio's participation in the interfund lending program
as a borrower and as a lender.
 
    The Board of Trustees believes that the interfund lending program: (i) may
benefit each Portfolio by providing it with greater flexibility to engage in
lending transactions; and (ii) could facilitate a Portfolio's ability to earn a
higher return on short-term investments by allowing it to lend cash to other
Affiliate Funds. Implementation of interfund lending would be accomplished
consistent with applicable regulatory requirements, including the provisions of
any order the SEC might issue to the Trust, on behalf of the Portfolios and to
other Affiliate Funds. The Trust has not yet applied for such order and there
can be no assurance that any such order would be granted, even if applied for.
 
                       THE BOARD OF TRUSTEES UNANIMOUSLY
                    RECOMMENDS THAT SHAREHOLDERS VOTE "FOR"
                          EACH ITEM IN PROPOSAL NO. 6
 
    If one or more of the changes contemplated by Proposal No. 6 are not
approved by the shareholders of one of the applicable Portfolios, the related
existing fundamental investment restriction(s) of that Portfolio will continue
in effect for that Portfolio. Disapproval of all or part of Proposal No. 6 by
 
                                       40

shareholders of one Portfolio will not affect any approvals of Proposal No. 6
that are obtained with respect to any other Portfolio.

                                 PROPOSAL NO. 7
 
    Subject to ratification by the shareholders at the Meeting, the Board of
Trustees, including all of the Disinterested Trustees, at a meeting held October
15, 1998, approved the selection of PricewaterhouseCoopers LLP as the
independent accountants for each of the Portfolios for the fiscal year ending
November 30, 1999.
 
    The firm of PricewaterhouseCoopers LLP and its predecessor entity has
extensive experience in investment company accounting and auditing and has
served as independent accountants to the Trust since its inception. The
financial statements included in the Trust's Annual Report have been examined by
PricewaterhouseCoopers LLP. It is not expected that a representative of
PricewaterhouseCoopers LLP will be present at the meeting.
 
    PricewaterhouseCoopers LLP and its members do not have any direct or
indirect material financial interest in or connection with the Trust or the
Portfolios in any capacity other than as independent accountants.

come before the Meeting, it is intended that the proxies will vote thereon in
their discretion.
 
                              GENERAL INFORMATION
 
SHAREHOLDER PROPOSALS AND SHAREHOLDER MEETINGS
 
    Notwithstanding the approval or disapproval of the proposals described
above, as in the past, the Trustees do not intend to hold annual meetings of
shareholders of the Trust. If a shareholder wishes to present a proposal to be
included in the proxy statement for the next meeting of shareholders of a
Portfolio, such proposal must be received by the Trust a reasonable time before
the solicitation is to be made. The Trustees will call meetings of shareholders
of a Trust or a Portfolio as may be required under the 1940 Act (such as to
approve a new investment advisory agreement for a Portfolio) or as they may
determine in their discretion. The Trustees will call a meeting of shareholders
to elect additional Trustees if more than 50% of the Trustees were not elected
by shareholders. The Trust's By-laws require the Trustees to call a meeting of
shareholders when requested in writing to do so by shareholders holding a
majority of the outstanding shares of beneficial interest of the Trust, provided
that, pursuant to Section 16(c) of the 1940 Act, a meeting requested exclusively
for the stated purpose of removing a Trustee shall be called when requested in
writing to do so by the record holders of not less than 10% of the outstanding
shares. The costs of such meetings will be borne by the applicable Portfolio.

                  INVESTMENT ADVISORY AND MANAGEMENT AGREEMENT
 
    This INVESTMENT ADVISORY AND MANAGEMENT AGREEMENT is dated as of
____________, between SUNAMERICA SERIES TRUST, a Massachusetts business trust
(the "Trust") and SUNAMERICA ASSET MANAGEMENT CORP., a Delaware corporation (the
"Adviser" or "SAAMCo").
 
    In consideration of the mutual agreements herein made, the parties hereto
agree as follows:
 
    1.  THE TRUST'S PORTFOLIOS.  The Trust is authorized to issue shares in
separate series, with each series representing interests in a separate portfolio
of securities and other assets, and currently offers shares of the series set
forth in Schedule A attached hereto (the "Portfolios"). It is recognized that
additional Portfolios may be added and certain current Portfolios may be deleted
in the future.
 
    2.  DUTIES OF THE ADVISER.  The Adviser shall manage the affairs of the
Trust as set forth herein, either by taking such actions itself or by delegating
its duties to a subadviser pursuant to a written subadvisory agreement. Such
duties shall include, but not limited to, continuously providing the Trust with
investment management, including investment research, advice and supervision,
determining which securities shall be purchased or sold by each Portfolio of the
Trust and making purchases and sales of securities on behalf of each Portfolio.
The Adviser's management shall be subject to the control of the Trustees of the
Trust (the "Trustees") and in accordance with the objectives, policies and
restrictions for each such Portfolio set forth in the Trust's Registration
Statement and its current Prospectus and Statement of Additional Information, as
amended from time to time, the requirements of the Investment Company Act of
1940, as amended (the "Act") and other applicable law, as well as to the factors
affecting the Trust's status as a regulated investment company under the
Internal Revenue Code of 1986, as amended, (the "Code") and the regulations
thereunder and the status of variable contracts under the diversification
requirements set forth in Section 817(h) of the Code and the regulations
thereunder. In performing such duties, the Adviser shall (i) provide such office
space, bookkeeping, accounting, clerical, secretarial and administrative
services (exclusive of, and in addition to, any such service provided by any
others retained by the Trust or any of its Portfolios) and such executive and
other personnel as shall be necessary for the operations of each Portfolio, (ii)
be responsible for the financial and accounting records required to be
maintained by each Portfolio (including those maintained by the Trust's
custodian), and (iii) oversee the performance of services provided to each
Portfolio by others, including the custodian, transfer agent, shareholder
servicing agent and subadviser, if any. The Trust acknowledges that the Adviser
also acts as the manager of other investment companies.
 
    With respect to the Cash Management Portfolio, the Adviser hereby accepts
the responsibilities for making the determinations required by Rule 2a-7 under
the Act to be made by the Trustees of the Trust and which are delegable by the
Trustees pursuant to paragraph (e) of such Rule, to the extent that the Trustees
may hereinafter delegate such responsibilities to the Adviser.
 
    The Adviser may delegate certain of its duties under this Agreement with
respect to a Portfolio to a subadviser pursuant to a written agreement, subject
to the approval of the Trustees and a Portfolio's shareholders, as required by
the Act. The Adviser is solely responsible for payment of any fees or other
charges to a subadviser arising from such delegation and the Trust shall have no
liability therefor.
 
    3.  EXPENSES.  The Adviser shall pay all of its expenses arising from the
performance of its obligations under this Agreement and shall pay any salaries,
fees and expenses of the Trustees and any officers of the Trust who are
employees of the Adviser. The Adviser shall not be required to pay any other
expenses of the Trust, including, but not limited to, direct charges relating to
the purchase and sale of portfolio securities, interest charges, fees and
expenses of independent attorneys and auditors, taxes and governmental fees,
cost of stock certificates and any other expenses (including clerical expenses)
of issue, sale, repurchase or redemption of shares, expenses of registering and
qualifying shares for sale, expenses of
 
                                      A-1
<PAGE>
printing and distributing reports, notices and proxy materials to shareholders,
expenses of data processing and related services, shareholder recordkeeping and
shareholder account service, expenses of printing and filing reports and other
documents filed with governmental agencies, expenses of printing and
distributing prospectuses, expenses of annual and special shareholders'
meetings, fees and disbursements of transfer agents and custodians, expenses of
disbursing dividends and distributions, fees and expenses of Trustees who are
not employees of the Adviser or its affiliates, membership dues in the
Investment Company Institute, insurance premium dues in the Investment Company
Institute, insurance premiums and extraordinary expenses such as litigation
expenses.
 
    4.  COMPENSATION.  (a) As compensation for services performed and the
facilities and personnel provided by the Adviser under this Agreement, the Trust
will pay to the Adviser, promptly after the end of each month for the services
rendered by the Adviser during the preceding month, the sum of the amounts set
forth in Schedule A attached hereto calculated in accordance with the average
daily net assets of the indicated Portfolio.
 
    To the extent required by the laws of any state in which the Trust is
subject to an expense guarantee limitation, if the aggregate expenses of any
Portfolio in any fiscal year exceed the specified expense limitation ratios for
that year (calculated on a daily basis), the Adviser agrees to waive such
portion of its advisory fee in excess of the limitation, but such waiver shall
not exceed the full amount of the advisory fee for such year except as may be
elected by Adviser in its discretion. For this purpose, aggregate expenses of a
Portfolio shall include the compensation of the Adviser and all normal expenses,
fees and charges, but shall exclude interest, taxes, brokerage fees on portfolio
transactions, fees and expenses incurred in connection with the distribution of
Trust shares, and extraordinary expenses including litigation expenses. In the
event any amounts are so contributed by the Adviser to the Trust, the Trust
agrees to reimburse the Adviser for any expenses waived, provided that such
reimbursement does not result in increasing the Trust's aggregate expenses above
the aforementioned expense limitation ratios.
 
    The Adviser's fee shall be accrued daily at 1/365th of the applicable annual
rate set forth above. For the purpose of accruing compensation, the net assets
of the Portfolio shall be that determined in the manner and on the dates set
forth in the current prospectus of the Trust and, on days on which the net
assets are not so determined, the net asset computation to be used shall be as
determined on the next day on which the net assets shall have been determined.
 
    (b) Upon any termination of this Agreement on a day other than the last day
of the month, the fee for the period from the beginning of the month in which
termination occurs to the date of termination shall be prorated according to the
proportion which such period bears to the full month.
 
    5.  PURCHASE AND SALE OF SECURITIES.  The Adviser shall purchase securities
from or though and sell securities to or through such persons, brokers or
dealers as the Adviser shall deem appropriate in order to carry out the policies
with respect to portfolio transactions as set forth in the Trust's Registration
Statement and its current Prospectus or Statement of Additional Information, as
amended from time to time, or as the Trustees may direct from time to time.
 
    Nothing herein shall prohibit the Trustees from approving the payment by the
Trust of additional compensation to others for consulting services, supplemental
research and security and economic analysis.
 
    6.  TERM OF AGREEMENT.  This Agreement shall continue in full force and
effect with respect to each Portfolio until two years from the date approved by
the Trustees of the Trust in respect of such Portfolio, and from year to year
thereafter so long as such continuance is approved at least annually (i) by the
Trustees by vote cast in person at a meeting called for the purpose of voting on
such renewal, or by the vote of a majority of the outstanding voting securities
(as defined by the Act) of such Portfolio with respect to which renewal is to be
effected, and (ii) by a majority of the non-interested Trustees by vote cast in
person at a meeting called for the purpose of voting on such renewal. Any
approval of this Agreement or the renewal thereof with respect to a Portfolio by
the vote of a majority of the outstanding voting securities of
 
                                      A-2
<PAGE>
that Portfolio, or by the Trustees of the Trust which shall include a majority
of the non-interested Trustees, shall be effective to continue this Agreement
with respect to that Portfolio notwithstanding (a) that this Agreement or the
renewal thereof has not been so approved as to any other Portfolio, or (b) that
this Agreement or the renewal thereof has not been so approved by the vote of a
majority of the outstanding voting securities of the Trust as a whole.
 
    7.  TERMINATION.  This Agreement may be terminated at any time as to a
Portfolio, without payment of any penalty, by the Trustees or by the vote of a
majority of the outstanding voting securities (as defined in the Act) of such
Portfolio on sixty (60) days' written notice to the Adviser. Similarly, the
Adviser may terminate this Agreement without penalty on like notice to the Trust
provided, however, that this Agreement may not be terminated by the Adviser
unless another investment advisory agreement has been approved by the Trust in
accordance with the Act, or after six months' written notice, whichever is
earlier. This Agreement shall automatically terminate in the event of its
assignment (as defined in the Act).
 
    8.  REPORTS.  The Adviser shall report to the Trustees, or to any committee
or officers of the Trust acting pursuant to the authority of the Trustees, at
such times and in such detail as shall be reasonable and as the Board may deem
appropriate in order to enable the Trust to determine that the investment
policies of each Portfolio are being observed and implemented and that the
obligations of the Adviser under this Agreement are being fulfilled. Any
investment program undertaken by the Adviser pursuant to this Agreement and any
other activities undertaken by the Adviser on behalf of the Trust shall at all
times be subject to any directives of the Trustees or any duly constituted
committee or officer of the Trust acting pursuant to the authority of the
Trustees.
 
    9.  RECORDS.  The Trust is responsible for maintaining and preserving for
such period or periods as the Securities and Exchange Commission may prescribe
by rules and regulations, such accounts, books and other documents as constitute
the records forming the basis for all reports, including financial statements
required to be filed pursuant to the Act and for the Trust's auditor's
certification relating thereto. The Adviser hereby undertakes and agrees to
maintain in the form and for the periods required by Rule 31a-2 under the Act,
all records relating to the Portfolio's investments that are required to be
maintained pursuant to the requirements of Rule 31a-1 of the Act.
 
    The Adviser and the Trust agree that all accounts, books and other records
maintained and preserved by each as required hereby shall be subject at any
time, and from time to time, to such reasonable periodic, special and other
examinations by the Securities and Exchange Commission, the Trust's auditors,
the Trust or any representative of the Trust, or any governmental agency or
other instrumentality having regulatory authority over the Trust. It is
expressly understood and agreed that the books and records maintained by the
Adviser on behalf of each Portfolio shall, at all times, remain the property of
the Trust.
 
    10.  LIABILITY OF ADVISER.  In the absence of willful misfeasance, bad
faith, gross negligence or reckless disregard of obligations or duties
("disabling conduct") hereunder on the part of the Adviser (and its officers,
directors, agents, employees, controlling persons, shareholders and any other
person or entity affiliated with the Adviser), the Adviser shall not be subject
to liability to the Trust or to any other person for any act or omission in the
course of, or connected with, rendering services hereunder including, without
limitation, any error of judgment or mistake of law or for any loss suffered by
any of them in connection with the matters to which this Agreement relates,
except to the extent specified in Section 36(b) of the Act concerning loss
resulting from a breach of fiduciary duty with respect to the receipt of
compensation for services. Except for such disabling conduct or liability under
Section 36(b) of the Act, the Trust shall indemnify the Adviser (and its
officers, directors, agents, employees, controlling persons, shareholders and
any other person or entity affiliated with the Adviser) from any liability
arising from the Adviser's conduct under this Agreement.
 
    Indemnification to the Adviser or any of its personnel or affiliates shall
be made when (A) a final decision on the merits rendered, by a court or other
body before whom the proceeding was brought, that the person to be indemnified
was not liable by reason of disabling conduct or, (B) in the absence of such a
 
                                      A-3
<PAGE>
decision, a reasonable determination, based upon a review of the facts, that the
person to be indemnified was not liable by reason of disabling conduct, by (a)
the vote of a majority of a quorum of Trustees who are neither "interested
persons" of the Trust as defined in Section 2(a)(19) of the Act nor parties to
the proceeding ("disinterested, non-party Trustees"), or (b) an independent
legal counsel in a written opinion. The Trust may, by vote of a majority of the
disinterested, non-party Trustees, advance attorneys' fees or other expenses
incurred by officers, Trustees, investment advisers, subadvisers or principal
underwriters, in defending a proceeding upon the undertaking by or on behalf of
the person to be indemnified to repay the advance unless it is ultimately
determined that such person is entitled to indemnification. Such advance shall
be subject to at least one of the following: (i) the person to be indemnified
shall provide adequate security for his undertaking, (ii) the Trust shall be
insured against losses arising by reason of any lawful advances, or (iii) a
majority of a quorum of the disinterested, non-party Trustees, or an independent
legal counsel in a written opinion, shall determine, based on a review of
readily available facts, that there is reason to believe that the person to be
indemnified ultimately will be found entitled to indemnification.
 
    11.  MISCELLANEOUS.  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.
 
    The Declaration of Trust establishing the Trust, a copy of which is on file
in the office of the Secretary of the Commonwealth of Massachusetts, provides
that the name of the Trust refers to the Trustees collectively as Trustees, not
as individuals or personally; and that no Trustee, shareholder, officer,
employee or agent of the Trust shall be held to any personal liability, nor
shall resort be had to their private property for the satisfaction of any
obligation or claim or otherwise in connection with the affairs of the Trust or
any Portfolio; but that the Trust Estate shall be liable. Notice is hereby given
that nothing contained herein shall be construed to be binding upon any of the
Trustees, officers, or shareholders of the Trust individually.
 
    IN WITNESS WHEREOF, the Trust and the Adviser have caused this Agreement to
be executed by their duly authorized officers as of the date first above
written.

                             SUBADVISORY AGREEMENT
                   BETWEEN SUNAMERICA ASSET MANAGEMENT CORP.
                                      AND
                        ALLIANCE CAPITAL MANAGEMENT L.P.
 
    It is hereby agreed by and between SUNAMERICA ASSET MANAGEMENT CORP. (the
"Adviser") and ALLIANCE CAPITAL MANAGEMENT L.P. ("Subadviser") as follows:
 
    1.  DUTIES OF SUBADVISER.  Adviser hereby engages the services of Subadviser
in furtherance of its Investment Advisory and Management Agreement with
SunAmerica Series Trust (the "Trust") dated as of                      , on
behalf of the Alliance Growth Portfolio, the Growth-Income Portfolio and the
Global Equities Portfolio (each, a "Portfolio," and collectively, the
"Portfolios"). Pursuant to this Sub-Advisory Agreement and subject to the
oversight and review of Adviser, Subadviser will manage the investment and
reinvestment of the assets of the Portfolio. In this regard, Subadviser will
determine in its discretion the securities to be purchased or sold, will provide
Adviser with records concerning its activities which Adviser or the Trust is
required to maintain, and will render regular reports to Adviser and to officers
and Trustees of the Trust concerning its discharge of the foregoing
responsibilities. Subadviser shall discharge the foregoing responsibilities
subject to the control of the officers and the Trustees of the Trust and in
compliance with such policies as the Trustees of the Trust may from time to time
establish, and in compliance with the objectives, policies, and limitations for
the Portfolios set forth in the Trust's current prospectus and statement of
additional information, and applicable laws and regulations. Subadviser accepts
such employment and agrees, at its own expense, to render the services set forth
herein and to provide the office space, furnishings, equipment and personnel
required by it to perform such services on the terms and for the compensation
provided in this Agreement.
 
    2.  PORTFOLIO TRANSACTIONS.  Subadviser is authorized to select the brokers
or dealers that will execute the purchases and sales of portfolio securities and
is directed to use its best efforts to obtain the best price and execution.
Subject to policies established by the Trustees of the Trust, Subadviser may
also be authorized to effect individual securities transactions at commission
rates in excess of the minimum commission rates available, if Subadviser
determines in good faith that such amount of commission is reasonable in
relation to the value of the brokerage and research services provided by such
broker or dealer, viewed in terms of either that particular transaction or
Subadviser's overall responsibilities with respect to a Portfolio, other
portfolios of the Trust and other clients of Subadviser. The execution of such
transactions shall not be deemed to represent an unlawful act or breach of any
duty created by this Agreement or otherwise. Subadviser will promptly
communicate to Adviser and to the officers and the Trustees of the Trust such
information relating to portfolio transactions as they may reasonably request.
 
    3.  COMPENSATION OF SUBADVISER.  As its compensation hereunder, the Adviser
shall pay to Subadviser promptly after the end of each month, a fee calculated
in accordance with the average daily net assets of the indicated Portfolio as
follows:
 
    ALLIANCE GROWTH PORTFOLIO:
 
    .35% per annum on the first $50 million;
    .30% per annum on the next $100 million;

    To the extent required by the laws of any state in which the Trust is
subject to an expense guarantee limitation, if the aggregate expenses of any
Portfolio in any fiscal year exceed the specified expense limitation ratios for
that year (calculated on a daily basis), as a result of which Adviser is
required to reduce or refund its advisory and management fee payable by a
Portfolio, Subadviser agrees to waive such portion of its subadvisory fee in the
same proportion as the fees waived by the Adviser bear to the total advisory and
management fee paid by such Portfolio. Such waiver, however, shall not exceed
the full amount of the subadvisory fee for such year except as may be elected by
Subadviser in its discretion. For this purpose, aggregate expenses of a
Portfolio shall include the compensation of Adviser and all normal expenses,
fees and charges, but shall exclude interest, taxes, brokerage fees on portfolio
transactions, fees and expenses incurred in connection with the distribution of
Trust shares, and extraordinary expenses including litigation expenses. In the
event any amounts are so contributed by Subadviser to Adviser, Adviser agrees to
reimburse Subadviser for any expenses waived, provided that Adviser has been
reimbursed by the Trust.
 
    Subadviser's fee shall be accrued daily at 1/365th of the applicable annual
rate set forth above. For the purpose of accruing compensation, the net assets
of a Portfolio shall be that determined in the manner and on the dates set forth
in the current prospectus of the Trust and, on days on which the net assets are
not so determined, the net asset computation to be used shall be as determined
on the next day on which the net assets shall have been determined.
 
    4.  REPORTS.  Adviser and Subadviser agree to furnish to each other, if
applicable, current prospectuses, statements of additional information, proxy
statements, reports of shareholders, certified copies of their financial
statements, and such other information with regard to their affairs and that of
the Trust as each may reasonably request.
 
    5.  STATUS OF SUBADVISER.  The services of Subadviser to Adviser and the
Trust are not to be deemed exclusive, and Subadviser shall be free to render
similar services to others so long as its services to the Trust are not impaired
thereby. Subadviser shall be deemed to be an independent contractor and shall,
unless otherwise expressly provided or authorized, have no authority to act for
or represent the Trust in any way or otherwise be deemed an agent of the Trust.
 
    6.  CERTAIN RECORDS.  Subadviser hereby undertakes and agrees to maintain,
in the form and for the period required by Rule 31a-2 under the Investment
Company Act of 1940, all records relating to the Portfolios' investments that
are required to be maintained by the Trust pursuant to the requirements of Rule
31a-1 of that Act. Any records required to be maintained and preserved pursuant
to the provisions of Rule 31a-1 and Rule 31a-2 promulgated under the Investment
Company Act of 1940 which are prepared or maintained by Subadviser on behalf of
the Trust are the property of the Trust and will be surrendered promptly to the
Trust or Adviser on request.
 
                                     C-1-2
<PAGE>
    Subadviser agrees that all accounts, books and other records maintained and
preserved by it as required hereby shall be subject at any time, and from time
to time, to such reasonable periodic, special and other examinations by the
Securities and Exchange Commission, the Trust's auditors, the Trust or any
representative of the Trust, the Adviser, or any governmental agency or other
instrumentality having regulatory authority over the Trust.
 
    7.  REFERENCE TO SUBADVISER.  Neither the Trust nor Adviser or any affiliate
or agent thereof shall make reference to or use the name of Subadviser or any of
its affiliates in any advertising or promotional materials without the prior
approval of Subadviser, which approval shall not be unreasonably withheld.
Subadviser agrees to notify Adviser of any changes in the membership of the
general partners of Subadviser as soon as practicable prior to such change.
 
    8.  LIABILITY OF SUBADVISER.  In the absence of willful misfeasance, bad
faith, gross negligence or reckless disregard of obligations or duties
("disabling conduct") hereunder on the part of Subadviser (and its officers,
directors, agents, employees, controlling persons, shareholders and any other
person or entity affiliated with Subadviser), Subadviser shall not be subject to
liability to the Adviser or to any other person for any act or omission in the
course of, or connected with, rendering services hereunder including, without
limitation, any error of judgment or mistake of law or for any loss suffered by
any of them in connection with the matters to which this Agreement relates,
except to the extent specified in Section 36(b) of the Investment Company Act of
1940 concerning loss resulting from a breach of fiduciary duty with respect to
the receipt of compensation for services.
 
    9.  DURATION AND TERMINATION.  This Agreement shall continue in full force
and effect with respect to a Portfolio until the earlier of (a) two years from
the date this Agreement is approved by the Trustees, or (b) the first meeting of
the shareholders of such Portfolio after the date hereof. If approved at such
meeting by the affirmative vote of a majority of the outstanding voting
securities (as defined in the Investment Company Act of 1940), of the Portfolio
with respect to such Portfolio, voting separately from any other series of the
Trust, this Agreement shall continue in full force and effect with respect to
such Portfolio from year to year thereafter so long as such continuance is
specifically approved at least annually (i) by the vote of a majority of those
Trustees of the Trust who are not parties to this Agreement or interested
persons of any such party, cast in person at a meeting called for the purpose of
voting on such approval, and (ii) by the Trustees of the Trust or by vote of a
majority of the outstanding voting securities of the Portfolio voting separately
from any other series of the Trust, provided, however, that if the shareholders
fail to approve the Agreement as provided herein, Subadviser may continue to
serve hereunder in the manner and to the extent permitted by the Investment
Company Act of 1940 and rules thereunder. The foregoing requirement that
continuance of this Agreement be "specifically approved at least annually" shall
be construed in a manner consistent with the Investment Company Act of 1940 and
the rules and regulations thereunder.
 
    This Agreement may be terminated at any time, without the payment of any
penalty by vote of a majority of the Trustees of the Trust or by a vote of a
majority of the outstanding voting securities of a Portfolio on not less than 30
days nor more than 60 days written notice to Subadviser or by Subadviser at any
time without the payment of any penalty, on 90 days written notice to Adviser
and the Trust; provided, however, that this Agreement may not be terminated by
Subadviser unless another subadvisory agreement has been approved by the Trust
in accordance with the Investment Company Act of 1940, or after six months'
written notice, whichever is earlier. This Agreement shall automatically
terminate in the event of its assignment (as defined in the Investment Company
Act of 1940). Any notice under this Agreement shall be given in writing,
addressed and delivered, or mailed postage prepaid, to the other party at any
office of such party.
 
    As used in this Section 11, the terms "assignment," "interested persons,"
and a "vote of a majority of the outstanding voting securities" shall have the
respective meanings set forth in the Investment Company
 
                                     C-1-3
<PAGE>
Act of 1940 and the rules and regulations thereunder, subject to such exemptions
as may be granted by the Securities and Exchange Commission under said Act.
 
    This Agreement will also terminate in the event that the Investment Advisory
and Management Agreement by and between the Trust on behalf of the Portfolio and
Adviser referred to in Section 1 is terminated.
 
    10.  SEVERABILITY.  If any provision of this Agreement shall be held or made
invalid by a court decision, statute, rule or otherwise, the remainder of this
Agreement shall not be affected thereby.
 
    A copy of the Declaration of Trust of the Trust is on file with the
Secretary of the Commonwealth of Massachusetts, and notice is hereby given that
nothing contained herein shall be construed to be binding upon any of the
Trustees, officers, or shareholders of the Trust individually.
 
    IN WITNESS WHEREOF, the parties have caused their respective duly authorized
officers to execute this Agreement on this    day of         , 1998.

                             SUBADVISORY AGREEMENT
 
    This SUBADVISORY AGREEMENT is dated as of           , by and between
SUNAMERICA ASSET MANAGEMENT CORP., a Delaware corporation (the "Adviser"), and
DAVIS SELECTED ADVISERS, L.P., a Colorado limited partnership (the
"Subadviser").
 
                                  WITNESSETH:
 
    WHEREAS, the Adviser and SunAmerica Series Trust, a Massachusetts business
trust (the "Trust"), have entered into an Investment Advisory and Management
Agreement dated as of           , (the "Advisory Agreement") pursuant to which
the Adviser has agreed to provide investment management, advisory and
administrative services to the Trust; and
 
    WHEREAS, the Trust is registered under the Investment Company Act of 1940,
as amended (the "Act"), as an open-end management investment company and may
issue shares of beneficial interest in separately designated portfolios
representing separate funds with their own investment objectives, policies and
purposes; and
 
    WHEREAS, the Subadviser is engaged in the business of rendering investment
advisory services and is registered as an investment adviser under the
Investment Advisers Act of 1940, as amended; and
 
    WHEREAS, the Adviser desires to retain the Subadviser to furnish investment
advisory services to the investment portfolio or portfolios of the Trust listed
in Schedule A hereto (the "Portfolio(s)"), and the Subadviser is willing to
furnish such services;
 
    NOW, THEREFORE, it is hereby agreed between the parties hereto as follows:
 
    1.  DUTIES OF THE SUBADVISER.  (a) The Adviser hereby engages the services
of the Subadviser in furtherance of its Investment Advisory and Management
Agreement. Pursuant to this Subadvisory Agreement and subject to the oversight
and review of the Adviser, the Subadviser will manage the investment and
reinvestment of the assets of each Portfolio listed. The Subadviser will
determine in its discretion and subject to the oversight and review of the
Adviser, the securities to be purchased or sold, will provide the Adviser with
records concerning its activities which the Adviser or the Trust is required to
maintain, and will render regular reports to the Adviser and to officers and
Trustees of the Trust concerning its discharge of the foregoing
responsibilities. The Subadviser shall discharge the foregoing responsibilities
subject to the control of the officers and the Trustees of the Trust and in
compliance with such policies as the Trustees of the Trust may from time to time
establish, and in compliance with the objectives, policies, and limitations for
the Portfolio(s) set forth in the Trust's current prospectus and statement of
additional information, and applicable laws and regulations. The Adviser shall
inform the Subadviser of any requirements of the California Insurance Code (or
other applicable insurance Code, if any) and any regulations thereunder that
operate to limit or restrict the investments the Portfolio(s) may otherwise
make, and to inform the Subadviser promptly of any changes in such requirements.
 
    The Subadviser represents and warrants to the Adviser that each of the
Portfolios set forth in Schedule A will at all times be operated and managed (1)
in compliance with all applicable federal and state laws governing its
operations and investments; (2) so as not to jeopardize either the treatment of
the Polaris variable annuity contracts issued by Variable Separate Account (File
No. 33-47473; hereinafter "Contracts") as annuity contracts for purposes of the
Internal Revenue Code of 1986, as amended (the "Code"), or the eligibility of
the Contracts to qualify for sale to the public in any state where they may
otherwise be sold; and (3) to minimize any taxes and/or penalties payable by the
Trust or such Portfolio. Without limiting the foregoing, the Subadviser
represents and warrants (1) qualification, election and maintenance of such
election by each Portfolio to be treated as a "regulated investment company"
under subchapter M, chapter 1 of the Code, and (2) compliance with (a) the
provisions of the Act and
 
                                     C-2-1
<PAGE>
rules adopted thereunder; (b) the diversification requirements specified in the
Internal Revenue Service's regulations under Section 817(h) of the Code; (c)
applicable state insurance laws; (d) applicable federal and state securities,
commodities and banking laws; and (e) the distribution requirements necessary to
avoid payment of any excise tax pursuant to Section 4982 of the Code. The
Subadviser further represents and warrants that to the extent that any
statements or omissions made in any Registration Statement for the Contracts or
shares of the Trust, or any amendment or supplement thereto, are made in
reliance upon and in conformity with information furnished by the Subadviser
expressly for use therein, such Registration Statement and any amendments or
supplements thereto will, when they become effective, conform in all material
respects to the requirements of the Securities Act of 1933 and the rules and
regulations of the Commission thereunder (the "1933 Act") and the Act and will
not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading.
 
    The Subadviser accepts such employment and agrees, at its own expense, to
render the services set forth herein and to provide the office space,
furnishings, equipment and personnel required by it to perform such services on
the terms and for the compensation provided in this Agreement.
 
    (b) In performing its investment advisory services, Subadviser, while
remaining ultimately responsible for management of the portion of the assets of
the Portfolio allocated to it, may delegate any of its responsibilities to one
of its affiliates, including Davis Selected Advisers--NY, Inc., its New York
affiliate.
 
    2.  PORTFOLIO TRANSACTIONS.  The Subadviser is authorized to select the
brokers or dealers that will execute the purchases and sales of portfolio
securities and is directed to use its best efforts to obtain the best price and
execution. In selecting such broker or dealers, the Subadviser shall consider
all relevant factors, including price (including the applicable brokerage
commission or dealer spread), the size of the order, the nature of the market
for the security or other investment, the timing of the transaction, the
reputation, experience and financial stability of the broker or dealer involved,
the quality of the service, the difficulty of execution, the execution
capabilities and operations facilities of the firm involved, and the firm's risk
in positioning a block of securities. Subject to such policies as the Trustees
may determine and consistent with Section 28(e) of the Securities Exchange Act
of 1934, as amended, the Subadviser shall not be deemed to have acted unlawfully
or to have breached any duty created by this Agreement or otherwise solely by
reason of the Subadviser's having caused a Portfolio to pay a member of an
exchange, broker or dealer an amount of commission for effecting a securities
transaction in excess of the amount of commission another member of an exchange,
broker or dealer would have charged for effecting that transaction, if the
Subadviser determines in good faith that such amount of commission was
reasonable in relation to the value of the brokerage and research services
provided by such member of an exchange, broker or dealer viewed in terms of
either that particular transaction or the Subadviser's overall responsibilities
with respect to such Portfolio and to other clients as to which the Subadviser
exercises investment discretion. The Subadviser will promptly communicate to the
Adviser and to the officers and the Trustees of the Trust such information
relating to portfolio transactions as they may reasonably request.
 
    3.  COMPENSATION OF THE SUBADVISER.  The Subadviser shall not be entitled to
receive any payment from the Trust and shall look solely and exclusively to the
Adviser for payment of all fees for the services rendered, facilities furnished
and expenses paid by it hereunder. As full compensation for the Subadviser under
this Agreement, the Adviser agrees to pay the Subadviser a fee at the annual
rates set forth in Schedule A hereto with respect to each Portfolio listed
thereon. Such fee shall be accrued daily and paid monthly as soon as practicable
after the end of each month (i.e., the applicable annual fee rate divided by 365
applied to each prior days' net assets in order to calculate the daily accrual).
For purposes of calculating the Subadviser's fee, the average daily net asset
value of a Portfolio shall be determined by taking an average of all
determinations of such net asset value during the month. If the Subadviser shall
provide its services under this Agreement for less than the whole of any month,
the foregoing compensation shall be prorated.
 
                                     C-2-2
<PAGE>
    The Subadviser, not the Adviser or the Trust, will pay Davis Selected
Advisers--NY, Inc., or any other affiliate the services of which are utilized
hereunder, all of such affiliate's reasonable direct and indirect costs
associated with maintenance of an office and performance of such services.
 
    To the extent required by the laws of any state in which the Trust is
subject to an expense guarantee limitation, if the aggregate expenses of any
Portfolio in any fiscal year exceed the specified expense limitation ratios for
that year (calculated on a daily basis), as a result of which the Adviser is
required to reduce or refund its advisory and management fee payable by the
Portfolio, the Subadviser agrees to waive such portion of its subadvisory fee in
the same proportion as the fees waived by the Adviser bear to the total advisory
and management fee paid by the Portfolio. Such waiver, however, shall not exceed
the full amount of the subadvisory fee for such year except as may be elected by
the Subadviser in its discretion. For this purpose, aggregate expenses of a
Portfolio shall include the compensation of the Adviser and all normal expenses,
fees and charges, but shall exclude interest, taxes, brokerage fees on portfolio
transactions, fees and expenses incurred in connection with the distribution of
Trust shares, and extraordinary expenses including litigation expenses. In the
event any amounts are so contributed by the Subadviser to the Adviser, the
Adviser agrees to reimburse the Subadviser for any expenses waived, provided
that the Adviser has been reimbursed by the Trust.
 
    4.  REPORTS.  The Adviser and the Subadviser agree to furnish to each other,
if applicable, current prospectuses, statements of additional information, proxy
statements, reports of shareholders, certified copies of their financial
statements, and such other information with regard to their affairs and that of
the Trust as each may reasonably request.
 
    5.  STATUS OF THE SUBADVISER.  The services of the Subadviser to the Adviser
and the Trust are not to be deemed exclusive, and the Subadviser shall be free
to render similar services to others so long as its services to the Trust are
not impaired thereby. The Subadviser shall be deemed to be an independent
contractor and shall, unless otherwise expressly provided or authorized, have no
authority to act for or represent the Trust in any way or otherwise be deemed an
agent of the Trust.
 
    6.  CERTAIN RECORDS.  The Subadviser hereby undertakes and agrees to
maintain, in the form and for the period required by Rule 31a-2 under the Act,
all records relating to the investments of the Portfolio(s) that are required to
be maintained by the Trust pursuant to the requirements of Rule 31a-1 of that
Act. Any records required to be maintained and preserved pursuant to the
provisions of Rule 31a-1 and Rule 31a-2 promulgated under the Act which are
prepared or maintained by the Subadviser on behalf of the Trust are the property
of the Trust and will be surrendered promptly to the Trust or the Adviser on
request.
 
    The Subadviser agrees that all accounts, books and other records maintained
and preserved by it as required hereby shall be subject at any time, and from
time to time, to such reasonable periodic, special and other examinations by the
Securities and Exchange Commission, the Trust's auditors, the Trust or any
representative of the Trust, the Adviser, or any governmental agency or other
instrumentality having regulatory authority over the Trust.
 
    7.  REFERENCE TO THE SUBADVISER.  Neither the Trust nor the Adviser or any
affiliate or agent thereof shall make reference to or use the name of the
Subadviser or any of its affiliates in any advertising or promotional materials
without the prior approval of the Subadviser, which approval shall not be
unreasonably withheld.
 
    8.  INDEMNIFICATION.  The Adviser agrees to indemnify and hold harmless the
Subadviser and its affiliates and each of its directors and officers and each
person, if any, who controls the Subadviser within the meaning of Section 15 of
the 1933 Act against any and all losses, claims, damages, liabilities or
litigation (including legal and other expenses), to which the Subadviser or its
affiliates or such directors, officers or controlling person may become subject
under the 1933 Act, under any other statute, at common law or otherwise, which
may be based upon any wrongful act or breach of this Agreement by the Adviser;
 
                                     C-2-3
<PAGE>
provided, however, that in no case is the Adviser's indemnity in favor of any
person deemed to protect such person against any liability to which such person
would otherwise be subject by reason of willful misfeasance, bad faith, or gross
negligence in the performance of his, her or its duties or by reasons of his,
her or its reckless disregard of obligations and duties under this Agreement.
 
    The Subadviser agrees to indemnify and hold harmless the Adviser and its
affiliates and each of its directors and officers and each person, if any, who
controls the Adviser within the meaning of Section 15 of the 1933 Act against
any and all losses, claims, damages, liabilities or litigation (including legal
and other expenses), to which the Adviser or its affiliates or such directors,
officers or controlling person may become subject under the 1933 Act, under
other statutes, at common law or otherwise, which may be based upon (i) any
wrongful act or breach of this Agreement by the Subadviser, or (ii) any failure
by the Subadviser to comply with the representations and warranties set forth in
Section 1 of this Agreement; provided, however, that in no case is the
Subadviser's indemnity in favor of any person deemed to protect such other
persons against any liability to which such person would otherwise be subject by
reasons of willful misfeasance, bad faith, or gross negligence in the
performance of his, her or its duties or by reason of his, her or its reckless
disregard of obligation and duties under this Agreement.
 
    9.  TERM OF THE AGREEMENT.  This Agreement shall continue in full force and
effect with respect to each Portfolio until the earlier of (a) two years from
the date this Agreement is approved by the Trustees, or (b) the first meeting of
the shareholders of the Portfolio of the Trust after the date hereof. If
approved at such meeting by the affirmative vote of a majority of the
outstanding voting securities (as defined in the Act), of the Portfolio with
respect to such Portfolio, voting separately from any other series of the Trust,
this Agreement shall continue in full force and effect with respect to such
Portfolio from year to year thereafter so long as such continuance is
specifically approved at least annually (i) by the vote of a majority of those
Trustees of the Trust who are not parties to this Agreement or interested
persons of any such party, cast in person at a meeting called for the purpose of
voting on such approval, and (ii) by the Trustees of the Trust or by vote of a
majority of the outstanding voting securities of the Portfolio voting separately
from any other series of the Trust, provided, however, that if the shareholders
fail to approve the Agreement as provided herein, the Subadviser may continue to
serve hereunder in the manner and to the extent permitted by the Act and rules
thereunder. The foregoing requirement that continuance of this Agreement be
"specifically approved at least annually" shall be construed in a manner
consistent with the Act and the rules and regulations thereunder.
 
    With respect to each Portfolio, this Agreement may be terminated at any
time, without payment of penalty by the Portfolio or the Trust, by vote of a
majority of the Trustees, or by vote of a majority of the outstanding voting
securities (as defined in the Act) of the Portfolio, voting separately from any
other series of the Trust, or by the Adviser, on not less than 30 nor more than
60 days' written notice to the Subadviser. With respect to each Portfolio, this
Agreement may be terminated by the Subadviser at any time, without the payment
of any penalty, on 90 days' written notice to the Adviser and the Trust;
provided, however, that this Agreement may not be terminated by the Subadviser
unless another subadvisory agreement has been approved by the Trust in
accordance with the Act, or after six months' written notice, whichever is
earlier. The termination of this Agreement with respect to any Portfolio or the
addition of any Portfolio to Schedule A hereto (in the manner required by the
Act) shall not affect the continued effectiveness of this Agreement with respect
to each other Portfolio subject hereto. This Agreement shall automatically
terminate in the event of its assignment (as defined by the Act).
 
    This Agreement will also terminate in the event that the Advisory Agreement
by and between the Trust and the Adviser is terminated.
 
    10.  SEVERABILITY.  If any provision of this Agreement shall be held or made
invalid by a court decision, statute, rule or otherwise, the remainder of this
Agreement shall not be affected thereby.
 
    11.  AMENDMENTS.  This Agreement may be amended by mutual consent in
writing, but the consent of the Trust must be obtained in conformity with the
requirements of the Act.
 
                                     C-2-4
<PAGE>
    12.  GOVERNING LAW.  This Agreement shall be construed in accordance with
the laws of the State of New York and the applicable provisions of the Act. To
the extent the applicable laws of the State of New York, or any of the
provisions herein, conflict with the applicable provisions of the Act, the
latter shall control.
 
    13.  PERSONAL LIABILITY.  The Declaration of the Trust establishing the
Trust (the "Declaration"), is on file in the office of the Secretary of the
Commonwealth of Massachusetts, and, in accordance with that Declaration, no
Trustee, shareholder, officer, employee or agent of the Trust shall be held to
any personal liability, nor shall resort be had to their private property for
satisfaction of any obligation or claim or otherwise in connection with the
affairs of the Trust, but the "Trust Property" only shall be liable.
 
    14.  SEPARATE SERIES.  Pursuant to the provisions of the Declaration, each
portfolio is a separate series of the Trust, and all debts, liabilities,
obligations and expenses of a particular portfolio shall be enforceable only
against the assets of that portfolio and not against the assets of any other
portfolio or of the Trust as a whole.
 
    15.  NOTICES.  All notices shall be in writing and deemed properly given

                             SUBADVISORY AGREEMENT
 
    This SUBADVISORY AGREEMENT is dated as of             by and between
SUNAMERICA ASSET MANAGEMENT CORP., a Delaware corporation (the "Adviser"), and
FEDERATED INVESTMENT COUNSELING, a Delaware business trust (the "Subadviser").
 
                                  WITNESSETH:
 
    WHEREAS, the Adviser and SunAmerica Series Trust, a Massachusetts business
trust (the "Trust"), have entered into an Investment Advisory and Management
Agreement dated as of             , (the "Advisory Agreement") pursuant to which
the Adviser has agreed to provide investment management, advisory and
administrative services to the Trust; and
 
    WHEREAS, the Trust is registered under the Investment Company Act of 1940,
as amended (the "Act"), as an open-end management investment company and may
issue shares of beneficial interest, par value $.01 per share, in separately
designated portfolios representing separate funds with their own investment
objectives, policies and purposes; and
 
    WHEREAS, the Subadviser is engaged in the business of rendering investment
advisory services and is registered as an investment adviser under the
Investment Advisers Act of 1940, as amended; and
 
    WHEREAS, the Adviser desires to retain the Subadviser to furnish investment
advisory services to the investment portfolio or portfolios of the Trust listed
on Schedule A attached hereto (the "Portfolio(s)"), and the Subadviser is
willing to furnish such services;
 
    NOW, THEREFORE, it is hereby agreed between the parties hereto as follows:
 
    1.  DUTIES OF THE SUBADVISER.  The Adviser hereby engages the services of
the Subadviser in furtherance of its Investment Advisory and Management
Agreement with the Trust. Pursuant to this Subadvisory Agreement and subject to
the oversight and review of the Adviser, the Subadviser will manage the
investment and reinvestment of the assets of each Portfolio listed on Schedule A
attached hereto. Subject to the oversight and review of the Adviser, the
Subadviser will determine in its discretion the securities to be purchased or
sold, and through delegated authority from the Adviser, execute such documents
as may be necessary in connection therewith; will provide the Adviser with
records concerning its activities which the Adviser or the Trust is required to
maintain; and will render regular reports to the Adviser and to officers and
Trustees of the Trust concerning its discharge of the foregoing
responsibilities. The Subadviser shall discharge the foregoing responsibilities
subject to the control of the officers and the Trustees of the Trust and in
compliance with such policies as the Trustees of the Trust may from time to time
establish, and in compliance with the objectives, policies, and limitations for
the Portfolio(s) set forth in the Trust's current prospectus and statement of
additional information.
 
    The Subadviser represents and warrants that its management of the Portfolios
will at all times conform with: (1) the objectives, policies, and limitations
for the Portfolio(s) set forth in the Trusts current prospectus and statement of
additional information; (2) the provisions of Subchapter M of the Internal
Revenue Code of 1986, as amended (the "Code"), applicable to regulated
investment companies, including those investment companies underlying variable
annuities; (3) the provisions of the Act and rules adopted thereunder applicable
to the Portfolios; (4) the diversification requirements specified in the
Internal Revenue Service's regulations under Section 817(h) of the Code; (5)
applicable state insurance laws provided to Subadviser by Adviser in writing
(which may be satisfied through delivery to Subadviser of a copy of the Trusts
current prospectus), or as acknowledged in a written undertaking by Subadviser;
(6) applicable federal and state securities laws; and (7) the distribution
requirements necessary to avoid payment of any excise tax pursuant to Section
4982 of the Code. The Subadviser further represents and
 
                                     C-3-1
<PAGE>
warrants that to the extent that any statements or omissions made in any
Registration Statement for the Contracts or shares of the Trust, or any
amendment or supplement thereto, are made in reliance upon and in conformity
with information furnished by the Subadviser expressly for use therein, such
Registration Statement and any amendments or supplements thereto will, when they
become effective, conform in all material respects to the requirements of the
Securities Act of 1933 and the rules and regulations of the Commission
thereunder (the "1933 Act") and the Act and will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading.
 
    The Subadviser accepts such employment and agrees, at its own expense, to
render the services set forth herein and to provide the office space,
furnishings, equipment and personnel required by it to perform such services on
the terms and for the compensation provided in this Agreement.
 
    2.  REPRESENTATIONS AND WARRANTIES OF THE ADVISER.  The Adviser represents
and warrants to the Subadviser that: (1) it is a corporation duly formed and
validly existing under the laws of Delaware; (2) it is duly authorized to
execute and deliver this Agreement and to perform its obligations thereunder;
and (3) it is registered with the Securities and Exchange Commission as an
investment adviser under the Investment Advisers Act of 1940, as amended.
 
    3.  PORTFOLIO TRANSACTIONS.  The Subadviser is responsible for decisions to
buy or sell securities and other investments of the assets of each Portfolio,
broker-dealers and futures commission merchants selection, and negotiation of
brokerage commission and futures commission merchants rates. As a general
matter, in executing portfolio transactions, the Subadviser may employ or deal
with such broker-dealers or futures commission merchants as may, in the
Subadviser's best judgement, provide prompt and reliable execution of the
transactions at favorable prices and reasonable commission rates. In selecting
such broker-dealers or futures commission merchants, the Subadviser shall
consider all relevant factors including price (including the applicable
brokerage commission, dealer spread or futures commission merchant rate), the
size of the order, the nature of the market for the security or other
investment, the timing of the transaction, the reputation, experience and
financial stability of the broker-dealer or futures commission merchant
involved, the quality of the service, the difficulty of execution, the execution
capabilities and operational facilities of the firm involved, and, in the case
of securities, the firm's risk in positioning a block of securities. Subject to
such policies as the Trustees may determine and consistent with Section 28(e) of
the Securities Exchange Act of 1934, as amended (the "1934 Act"), the Subadviser
shall not be deemed to have acted unlawfully or to have breached any duty
created by this Agreement or otherwise solely by reason of the Subadviser's
having caused a Portfolio to pay a member of an exchange, broker or dealer an
amount of commission for effecting a securities transaction in excess of the
amount of commission another member of an exchange, broker or dealer would have
charged for effecting that transaction, if the Subadviser determines in good
faith that such amount of commission was reasonable in relation to the value of
the brokerage and research services provided by such member of an exchange,
broker or dealer viewed in terms of either that particular transaction or the
Subadviser's overall responsibilities with respect to such Portfolio and to
other clients as to which the Subadviser exercises investment discretion. In
accordance with Section 11(a) of the 1934 Act and Rule 11a2-2(T) thereunder, and
subject to any other applicable laws and regulations including Section 17(e) of
the Act and Rule 17e-1 thereunder, the Subadviser may engage its affiliates, the
Adviser and its affiliates or any other subadviser to the Trust and its
respective affiliates, as broker-dealers or futures commission merchants to
effect portfolio transactions in securities and other investments for a
Portfolio. The Subadviser will promptly communicate to the Adviser and to the
officers and the Trustees of the Trust such information relating to portfolio
transactions as they may reasonably request. To the extent consistent with
applicable law, the Subadviser may aggregate purchase or sell orders for the
Portfolios with contemporaneous purchase or sell orders of other clients of the
Subadviser or its affiliated persons. In such event, allocation of the
securities so purchased or sold, as well as the expenses incurred in the
transaction, will be made by the Subadviser in the manner the Subadviser
determines to be equitable and consistent with its and its affiliates fiduciary
obligations to the
 
                                     C-3-2
<PAGE>
Portfolios and to such other clients. The Adviser hereby acknowledges that such
aggregation of orders may not result in more favorable pricing or lower
brokerage commissions in all instances.
 
    4.  COMPENSATION OF THE SUBADVISER.  The Subadviser shall not be entitled to
receive any payment from the Trust and shall look solely and exclusively to the
Adviser for payment of all fees for the services rendered, facilities furnished
and expenses paid by it hereunder. As full compensation for the Subadviser under
this Agreement, the Adviser agrees to pay the Subadviser a fee at the annual
rates set forth in Schedule A hereto with respect to each Portfolio listed
thereon. Such fee shall be accrued daily and paid monthly as soon as practicable
after the end of each month (i.e., the applicable annual fee rate divided by 365
applied to each prior days' net assets in order to calculate the daily accrual).
For purposes of calculating the Subadviser's fee, the average daily net asset
value of a Portfolio shall be determined by taking an average of all
determinations of such net asset value during the month. If the Subadviser shall
provide its services under this Agreement for less than the whole of any month,
the foregoing compensation shall be prorated.
 
    5.  REPORTS.  The Trust, the Adviser and the Subadviser agree to furnish to
each other, if applicable, current prospectuses, statements of additional
information, proxy statements, reports of shareholders, certified copies of
their financial statements, policies and procedures relating to the management
of the Trust as adopted by the Board of Trustees, and such other information
with regard to their affairs and that of the Trust as each may reasonably
request.
 
    6.  STATUS OF THE SUBADVISER.  The services of the Subadviser to the Adviser
and the Trust are not to be deemed exclusive, and the Subadviser shall be free
to render similar services to others so long as its services to the Trust are
not impaired thereby. The Subadviser shall be deemed to be an independent
contractor and shall, unless otherwise expressly provided or authorized, have no
authority to act for or represent the Trust in any way or otherwise be deemed an
agent of the Trust.
 
    7.  CERTAIN RECORDS.  The Subadviser hereby undertakes and agrees to
maintain, in the form and for the period required by Rule 31a-2 under the Act,
all records relating to the investments of the Portfolio(s) that are required to
be maintained by the Trust pursuant to the requirements of Rule 31a-1 of that
Act. Any records required to be maintained and preserved pursuant to the
provisions of Rule 31a-1 and Rule 31a-2 promulgated under the Act which are
prepared or maintained by the Subadviser on behalf of the Trust are the property
of the Trust and will be surrendered promptly to the Trust or the Adviser on
request.
 
    The Subadviser agrees that all accounts, books and other records maintained
and preserved by it as required hereby shall be subject at any time, and from
time to time, to such reasonable periodic, special and other examinations by the
Securities and Exchange Commission, the Trust's auditors, the Trust or any
representative of the Trust, the Adviser, or any governmental agency or other
instrumentality having regulatory authority over the Trust.
 
    8.  REFERENCE TO THE SUBADVISER.  Neither the Trust nor the Adviser or any
affiliate or agent thereof shall make reference to or use the name of the
Subadviser or any of its affiliates in any advertising or promotional materials
without the prior written approval of the Subadviser, which approval shall not
be unreasonably withheld.
 
    9.  LIABILITY OF THE SUBADVISER.  (a) In the absence of willful misfeasance,
bad faith, gross negligence or reckless disregard of obligations or duties
("disabling conduct") hereunder on the part of the Subadviser (and its officers,
directors, agents, employees, controlling persons, shareholders and any other
person or entity affiliated with the Subadviser) the Subadviser shall not be
subject to liability to the Trust or to any shareholder of the Trust for any act
or omission in the course of, or connected with, rendering services hereunder,
including without limitation, any error of judgment or mistake of law or for any
loss suffered by any of them in connection with the matters to which this
Agreement relates, except to the extent specified in Section 36(b) of the Act
concerning loss resulting from a breach of fiduciary duty with respect to the
 
                                     C-3-3
<PAGE>
receipt of compensation for services. Except for such disabling conduct, the
Adviser shall indemnify the Subadviser (and its officers, directors, partners,
agents, employees, controlling persons, shareholders and any other person or
entity affiliated with the Subadviser) (collectively, the "Indemnified Parties")
from any liability arising from the Subadvisers conduct under this Agreement.
Subadviser hereby indemnifies, defends and protects Adviser and holds Adviser
harmless, from and against any and all liability arising out of Subadvisers
disabling conduct.
 
    (b) The Subadviser agrees to indemnify and hold harmless the Adviser and its
affiliates and each of its directors and officers and each person, if any, who
controls the Adviser within the meaning of Section 15 of the 1933 Act against
any and all losses, claims, damages, liabilities or litigation (including legal
and other expenses), to which the Adviser or its affiliates or such directors,
officers or controlling person may become subject under the 1933 Act, under
other statutes, at common law or otherwise, which arise out of or result from
any breach of any representation or warranty set forth in Section 1 of this
Agreement; provided, however, that in no case is the Subadviser's indemnity in
favor of any person deemed to protect such other persons against any liability
to which such person would otherwise be subject by reasons of willful
misfeasance, bad faith, or gross negligence in the performance of his, her or
its duties or by reason of his, her or its reckless disregard of obligation and
duties under this Agreement.
 
    (c) The Adviser is hereby expressly put on notice of the limitation of
liability as set forth in the Declaration of Trust of the Subadviser and agrees
that the obligations assumed by the Subadviser pursuant to this Agreement will
be limited in any case to the Subadviser and its assets and the Adviser shall
not seek satisfaction of any such obligations from the shareholders of the
Subadviser, the trustees of the Subadviser, officers, employees or agents of the
Subadviser, or any of them.
 
    10.  PERMISSIBLE INTERESTS.  Trustees and agents of the Trust are or may be
interested in the Subadviser (or any successor thereof) as directors, partners,
officers, or shareholders, or otherwise; directors, partners, officers, agents,
and shareholders of the Subadviser are or may be interested in the Trust as
trustees, or otherwise; and the Subadviser (or any successor) is or may be
interested in the Trust in some manner.
 
    11.  TERM OF THE AGREEMENT.  This Agreement shall continue in full force and
effect with respect to each Portfolio until two years from the date hereof, and
from year to year thereafter so long as such continuance is specifically
approved at least annually (i) by the vote of a majority of those Trustees of
the Trust who are not parties to this Agreement or interested persons of any
such party, cast in person at a meeting called for the purpose of voting on such
approval, and (ii) by the Trustees of the Trust or by vote of a majority of the
outstanding voting securities of the Portfolio voting separately from any other
series of the Trust.
 
    With respect to each Portfolio, this Agreement may be terminated at any
time, without payment of a penalty by the Portfolio or the Trust, by vote of a
majority of the Trustees, or by vote of a majority of the outstanding voting
securities (as defined in the Act) of the Portfolio, voting separately from any
other series of the Trust, or by the Adviser, on not less than 30 nor more than
60 days' written notice to the Subadviser. With respect to each Portfolio, this
Agreement may be terminated by the Subadviser at any time, without the payment
of any penalty, on not less than 30 nor more than 60 days' written notice to the
Adviser and the Trust; provided, however, that this Agreement may not be
terminated by the Subadviser unless another subadvisory agreement has been
approved by the Trust in accordance with the Act, or after six months from the
date written notice is given, whichever is earlier. Notwithstanding the
requirements set forth in the immediately preceding sentence, Subadviser may
terminate this Agreement on 30 days' written notice upon the institution of
formal proceedings against the Adviser or the Trust by the NASD, the SEC, any
state securities or insurance department or any other regulatory body regarding
the Advisers obligations under this Agreement or related to the sale of the
Contracts, operation of the separate account, or sale of shares of the Trust,
provided that such formal proceedings are likely to have a material adverse
impact on the Subadviser. The termination of this Agreement with respect to any
Portfolio or the addition of any Portfolio to Schedule A hereto (in the manner
required by the Act) shall not affect the continued
 
                                     C-3-4
<PAGE>
effectiveness of this Agreement with respect to each other Portfolio subject
hereto. This Agreement shall automatically terminate in the event of its
assignment (as defined by the Act).
 
    This Agreement will also terminate in the event that the Advisory Agreement
by and between the Trust and the Adviser is terminated.
 
    12.  SEVERABILITY.  If any provision of this Agreement shall be held or made
invalid by a court decision, statute, rule or otherwise, the remainder of this
Agreement shall not be affected thereby.
 
    13.  AMENDMENTS.  This Agreement may be amended by mutual consent in
writing, but the consent of the Trust must be obtained in conformity with the
requirements of the Act.
 
    14.  GOVERNING LAW.  This Agreement shall be construed in accordance with
the laws of the State of New York and the applicable provisions of the Act. To
the extent the applicable laws of the State of New York, or any of the
provisions herein, conflict with the applicable provisions of the Act, the
latter shall control.
 
    15.  PERSONAL LIABILITY.  The Declaration of the Trust establishing the
Trust (the "Declaration"), is on file in the office of the Secretary of the
Commonwealth of Massachusetts, and, in accordance with that Declaration, no
Trustee, shareholder, officer, employee or agent of the Trust shall be held to
any personal liability, nor shall resort be had to their private property for
satisfaction of any obligation or claim or otherwise in connection with the
affairs of the Trust, but the "Trust Property" only shall be liable.
 
    16.  SEPARATE SERIES.  Pursuant to the provisions of the Declaration, each
Portfolio is a separate series of the Trust, and all debts, liabilities,
obligations and expenses of a particular Portfolio shall be enforceable only
against the assets of that Portfolio and not against the assets of any other
Portfolio or of the Trust as a whole.
 
    17.  NOTICES.  All notices shall be in writing and deemed properly given
when delivered or mailed by United States certified or registered mail, return

                             SUBADVISORY AGREEMENT
                   BETWEEN SUNAMERICA ASSET MANAGEMENT CORP.
                                      AND
                        GOLDMAN SACHS ASSET MANAGEMENT,
                        A SEPARATE OPERATING DIVISION OF
                              GOLDMAN, SACHS & CO.
 
    It is hereby agreed by and between SUNAMERICA ASSET MANAGEMENT CORP. (the
"Adviser") and GOLDMAN SACHS ASSET MANAGEMENT, a separate operating division of
GOLDMAN, SACHS & CO. ("Subadviser") as follows:
 
    1.  DUTIES OF SUBADVISER.  Adviser hereby engages the services of Subadviser
in furtherance of its Investment Advisory and Management Agreement with
SunAmerica Series Trust (the "Trust") dated as of         , on behalf of the
Asset Allocation Portfolio (the "Portfolio"). Pursuant to this Sub-Advisory
Agreement and subject to the oversight and review of Adviser, Subadviser will
manage the investment and reinvestment of the assets of the Portfolio. In this
regard, Subadviser will determine in its discretion the securities to be
purchased or sold, will provide Adviser with records concerning its activities
which Adviser or the Trust is required to maintain, and will render regular
reports to Adviser and to officers and Trustees of the Trust concerning its
discharge of the foregoing responsibilities. Subadviser shall discharge the
foregoing responsibilities subject to the control of the officers and the
Trustees of the Trust and in compliance with such policies as the Trustees of
the Trust may from time to time establish, and in compliance with the
objectives, policies, and limitations for the Portfolio set forth in the Trust's
current prospectus and statement of additional information, and applicable laws
and regulations. Adviser agrees to inform Subadviser of any and all requirements
of the California Insurance Code and regulations thereunder that operate to
limit or restrict the investments the Portfolio may otherwise make, and to
inform Subadviser promptly of any changes in such requirements. Subadviser
accepts such employment and agrees, at its own expense, to render the services
set forth herein and to provide the office space, furnishings, equipment and
personnel required by it to perform such services on the terms and for the
compensation provided in this Agreement.
 
    2.  PORTFOLIO TRANSACTIONS.  Subadviser is authorized to select the brokers
or dealers that will execute the purchases and sales of portfolio securities and
is directed to use its best efforts to obtain the best price and execution.
Subject to policies established by the Trustees of the Trust, Subadviser may
also be authorized to effect individual securities transactions at commission
rates in excess of the minimum commission rates available, if Subadviser
determines in good faith that such amount of commission is reasonable in
relation to the value of the brokerage and research services provided by such
broker or dealer, viewed in terms of either that particular transaction or
Subadviser's overall responsibilities with respect to a Portfolio, other
portfolios of the Trust and other clients of Subadviser. The execution of such
transactions shall not be deemed to represent an unlawful act or breach of any
duty created by this Agreement or otherwise. Subadviser will promptly
communicate to Adviser and to the officers and the Trustees of the Trust such
information relating to portfolio transactions as they may reasonably request.
 
                                     C-4-1
<PAGE>
    3.  COMPENSATION OF SUBADVISER.  As its compensation hereunder, the Adviser
shall pay to Subadviser promptly after the end of each month, a fee calculated
in accordance with the average daily net assets of the indicated Portfolio as
follows:
 
    ASSET ALLOCATION PORTFOLIO:
 
    .40% PER ANNUM ON THE FIRST $50 MILLION;
    .30% PER ANNUM ON THE NEXT $100 MILLION;
    .25% PER ANNUM ON THE NEXT $100 MILLION;
    .20% PER ANNUM THEREAFTER.
 
    To the extent required by the laws of any state in which the Trust is
subject to an expense guarantee limitation, if the aggregate expenses of any
Portfolio in any fiscal year exceed the specified expense limitation ratios for
that year (calculated on a daily basis), as a result of which Adviser is
required to reduce or refund its advisory and management fee payable by a
Portfolio, Subadviser agrees to waive such portion of its subadvisory fee in the
same proportion as the fees waived by the Adviser bear to the total advisory and
management fee paid by such Portfolio. Such waiver, however, shall not exceed
the full amount of the subadvisory fee for such year except as may be elected by
Subadviser in its discretion. For this purpose, aggregate expenses of a
Portfolio shall include the compensation of Adviser and all normal expenses,
fees and charges, but shall exclude interest, taxes, brokerage fees on portfolio
transactions, fees and expenses incurred in connection with the distribution of
Trust shares, and extraordinary expenses including litigation expenses. In the
event any amounts are so contributed by Subadviser to Adviser, Adviser agrees to
reimburse Subadviser for any expenses waived, provided that Adviser has been
reimbursed by the Trust.
 
    Subadviser's fee shall be accrued daily at 1/365th of the applicable annual
rate set forth above. For the purpose of accruing compensation, the net assets
of a Portfolio shall be that determined in the manner and on the dates set forth
in the current prospectus of the Trust and, on days on which the net assets are
not so determined, the net asset computation to be used shall be as determined
on the next day on which the net assets shall have been determined.
 
    4.  REPORTS.  Adviser and Subadviser agree to furnish to each other, if
applicable, current prospectuses, statements of additional information, proxy
statements, reports of shareholders, certified copies of their financial
statements, and such other information with regard to their affairs and that of
the Trust as each may reasonably request.
 
    5.  STATUS OF SUBADVISER.  The services of Subadviser to Adviser and the
Trust are not to be deemed exclusive, and Subadviser shall be free to render
similar services to others so long as its services to the Trust are not impaired
thereby. Subadviser shall be deemed to be an independent contractor and shall,
unless otherwise expressly provided or authorized, have no authority to act for
or represent the Trust in any way or otherwise be deemed an agent of the Trust.
 
    6.  CERTAIN RECORDS.  Subadviser hereby undertakes and agrees to maintain,
in the form and for the period required by Rule 31a-2 under the Investment
Company Act of 1940, all records relating to the Portfolio's investments that
are required to be maintained by the Trust pursuant to the requirements of Rule
31a-1 of that Act. Any records required to be maintained and preserved pursuant
to the provisions of Rule 31a-1 and Rule 31a-2 promulgated under the Investment
Company Act of 1940 which are prepared or maintained by Subadviser on behalf of
the Trust are the property of the Trust and will be surrendered promptly to the
Trust or Adviser on request.
 
    Subadviser agrees that all accounts, books and other records maintained and
preserved by it as required hereby shall be subject at any time, and from time
to time, to such reasonable periodic, special and other examinations by the
Securities and Exchange Commission, the Trust's auditors, the Trust or any
representative of the Trust, the Adviser, or any governmental agency or other
instrumentality having regulatory authority over the Trust.

<PAGE>
    7.  REFERENCE TO SUBADVISER.  Neither the Trust nor Adviser or any affiliate
or agent thereof shall make reference to or use the name of Subadviser or any of
its affiliates in any advertising or promotional materials without the prior
approval of Subadviser, which approval shall not be unreasonably withheld.
Subadviser agrees to notify Adviser of any changes in the membership of the
general partners of Subadviser as soon as practicable prior to such change.
 
    8.  LIABILITY OF SUBADVISER.  In the absence of willful misfeasance, bad
faith, gross negligence or reckless disregard of obligations or duties
("disabling conduct") hereunder on the part of Subadviser (and its officers,
directors, agents, partners, employees, controlling persons, shareholders and
any other person or entity affiliated with Subadviser ("associated persons")),
Subadviser and its associated persons shall not be subject to liability to the
Adviser or to any other person for any act or omission in the course of, or
connected with, rendering services hereunder (including, without limitation, as
a result of failure by Adviser, by any other affiliate of Anchor National Life
Insurance Company ("ANLIC"), or by ANLIC, to comply with this Agreement or the
requirements of Section 10506 of the California Insurance Code and regulations
duly adopted pursuant to such Section or, as a result of any error of judgment
or mistake of law or for any loss suffered by Advisor or any other person in
connection with the matters to which this Agreement relates), except to the
extent specified in Section 36(b) of the Investment Company Act of 1940
concerning loss resulting from a breach of fiduciary duty with respect to the
receipt of compensation for services.
 
    Adviser hereby indemnifies, defends and protects Subadviser and holds
Subadviser and its associated persons harmless from and against any and all
claims, demands, actions, losses, damages, liabilities, costs, charges, counsel
fees and expenses of any nature ("Losses") arising out of (i) any inaccuracy or
omission in any prospectus, registration statement, annual report or proxy
statement or advertising or promotional material pertaining to the Portfolio
("Documents") to the extent such Document contains information not supplied to
Adviser by Subadviser for inclusion in such Document, (ii) any breach of Adviser
of any representation or agreement contained in this Subadvisory Agreement,
(iii) any failure by Adviser, by any other affiliate of ANLIC, or by ANLIC, to
comply with the requirements of Section 10506 of the California Insurance Code
and regulations duly adopted pursuant to such Section, and (iv) any action taken
or omitted to be taken by Subadviser pursuant to this Subadvisory Agreement,
except to the extent such Losses result from Subadviser's breach of this
Subadvisory Agreement or Subadviser's disabling conduct. Subadviser hereby
indemnifies, defends and protects Adviser and holds Adviser harmless from and
against any and all Losses arising out of Subadviser's disabling conduct.
 
    9.  DURATION AND TERMINATION.  This Agreement shall continue in full force
and effect with respect to a Portfolio until the earlier of (a) two years from
the date this Agreement is approved by the Trustees, or (b) the first meeting of
the shareholders of such Portfolio after the date hereof. If approved at such
meeting by the affirmative vote of a majority of the outstanding voting
securities (as defined in the Investment Company Act of 1940), of the Portfolio
with respect to such Portfolio, voting separately from any other series of the
Trust, this Agreement shall continue in full force and effect with respect to
such Portfolio from year to year thereafter so long as such continuance is
specifically approved at least annually (i) by the vote of a majority of those
Trustees of the Trust who are not parties to this Agreement or interested
persons of any such party, cast in person at a meeting called for the purpose of
voting on such approval, and (ii) by the Trustees of the Trust or by vote of a
majority of the outstanding voting securities of the Portfolio voting separately
from any other series of the Trust, provided, however, that if the shareholders
fail to approve the Agreement as provided herein, Subadviser may continue to
serve hereunder in the manner and to the extent permitted by the Investment
Company Act of 1940 and rules thereunder. The foregoing requirement that
continuance of this Agreement be "specifically approved at least annually" shall
be construed in a manner consistent with the Investment Company Act of 1940 and
the rules and regulations thereunder.
 
    This Agreement may be terminated at any time, without the payment of any
penalty by vote of a majority of the Trustees of the Trust or by a vote of a
majority of the outstanding voting securities of a
 
                                     C-4-3
<PAGE>
Portfolio on not less than 30 days nor more than 60 days' written notice to
Subadviser or by Subadviser at any time without the payment of any penalty, on
90 days' written notice to Adviser and the Trust; provided, however, that this
Agreement may not be terminated by Subadviser unless another subadvisory
agreement has been approved by the Trust in accordance with the Investment
Company Act of 1940, or after six months' written notice, whichever is earlier.
This Agreement shall automatically terminate in the event of its assignment (as
defined in the Investment Company Act of 1940). Any notice under this Agreement
shall be given in writing, addressed and delivered, or mailed postage prepaid,
to the other party at any office of such party.
 
    As used in this Section 11, the terms "assignment," "interested persons,"
and a "vote of a majority of the outstanding voting securities" shall have the
respective meanings set forth in the Investment Company Act of 1940 and the
rules and regulations thereunder, subject to such exemptions as may be granted
by the Securities and Exchange Commission under said Act.
 
    This Agreement will also terminate in the event that the Investment Advisory
and Management Agreement by and between the Trust on behalf of the Portfolio and
Adviser referred to in Section 1 is terminated.
 
    10.  SEVERABILITY.  If any provision of this Agreement shall be held or made
invalid by a court decision, statute, rule or otherwise, the remainder of this
Agreement shall not be affected thereby.
 
    A copy of the Declaration of Trust of the Trust is on file with the
Secretary of the Commonwealth of Massachusetts, and notice is hereby given that
nothing contained herein shall be construed to be binding upon any of the
Trustees, officers, or shareholders of the Trust individually.
 
    IN WITNESS WHEREOF, the parties have caused their respective duly authorized
officers to execute this Agreement as of                .

in furtherance of its Investment Advisory and Management Agreement with
SunAmerica Series Trust (the "Trust") dated as of         , on behalf of the

Subadviser will determine in its discretion the securities to be purchased or
sold, will provide Adviser with records concerning its activities which Adviser
or the Trust is required to maintain, and will render regular reports to Adviser
and to officers and Trustees of the Trust concerning its discharge of the
foregoing responsibilities. Subadviser shall discharge the foregoing
responsibilities subject to the control of the officers and the Trustees of the
Trust and in compliance with such policies as the Trustees of the Trust may from
time to time establish, and in compliance with the objectives, policies, and
limitations for the Portfolio set forth in the Trust's current prospectus and
statement of additional information, and applicable laws and regulations.
Adviser agrees to inform Subadviser of any and all requirements of the
California Insurance Code and regulations thereunder that operate to limit or

Subadviser promptly of any changes in such requirements. Subadviser accepts such
employment and agrees, at its own expense, to render the services set forth

provided in this Agreement.

relation to the value of the brokerage and research services provided by such
broker or dealer, viewed in terms of either that particular transaction or
Subadviser's overall responsibilities with respect to the Portfolio, other
portfolios of the Trust and other clients of Subadviser. The execution of such
transactions shall not be deemed to represent an unlawful act or breach of any
duty created by this Agreement or otherwise. Subadviser will promptly
communicate to Adviser and to the officers and the Trustees of the Trust such
information relating to portfolio transactions as they may reasonably request.

    To the extent required by the laws of any state in which the Trust is
subject to an expense guarantee limitation, if the aggregate expenses of the
Portfolio in any fiscal year exceed the specified expense limitation ratios for

required to reduce or refund its advisory and management fee payable by the
Portfolio, Subadviser agrees to waive such portion of its subadvisory fee in the

management fee paid by the Portfolio. Such waiver, however, shall not exceed the
full amount of the subadvisory fee for such year except as may be elected by

Portfolio shall include the compensation of Adviser and all normal expenses,
fees and charges, but shall exclude interest, taxes, brokerage fees on portfolio
transactions, fees and expenses incurred in connection with the distribution of
Trust shares, and extraordinary expenses including litigation expenses. In the
event any amounts are so contributed by Subadviser to Adviser, Adviser agrees to
reimburse Subadviser for any expenses waived, provided that Adviser has been
reimbursed by the Trust.

unless otherwise expressly provided or authorized, have no authority to act for

    6.  CERTAIN RECORDS.  Subadviser hereby undertakes and agrees to maintain,
in the form and for the period required by Rule 31a-2 under the Investment
Company Act of 1940, all records relating to the Portfolio's investments that

its affiliates in any advertising or promotional materials without the prior
approval of Subadviser, which approval shall not be unreasonably withheld.
 
    8.  LIABILITY OF SUBADVISER.  In the absence of willful misfeasance, bad
faith, gross negligence or reckless disregard of obligations or duties
("disabling conduct") hereunder on the part of Subadviser (and its officers,
directors, agents, partners, employees, controlling persons, shareholders and
any other person or entity affiliated with Subadviser ("associated persons")),
Subadviser and its associated persons shall not be subject to liability to the
Adviser or to any other person for any act or omission in the course of, or
connected with, rendering services hereunder (including, without limitation, as
a result of failure by Adviser, by any other affiliate of Anchor National Life
Insurance Company ("ANLIC"), or by ANLIC, to comply with this Agreement or the

of any representation or agreement contained in this Subadvisory Agreement,
(iii) any failure by Adviser, by any other affiliate of ANLIC, or by ANLIC, to
comply with the requirements of Section 10506 of the California Insurance Code
and regulations duly adopted pursuant to such Section, and (iv) any action taken
or omitted to be taken by Subadviser pursuant to this Subadvisory Agreement,
except to the extent such Losses result from Subadviser's breach of this
Subadvisory Agreement or Subadviser's disabling conduct. Subadviser hereby
indemnifies, defends and protects Adviser and holds Adviser harmless from and
against any and all Losses arising out of Subadviser's disabling conduct.
 
    9.  DURATION AND TERMINATION.  This Agreement shall continue in full force
and effect with respect to the Portfolio until the earlier of (a) two years from
the date this Agreement is approved by the Trustees, or (b) the first meeting of
the shareholders of the Portfolio after the date hereof. If approved at such
meeting by the affirmative vote of a majority of the outstanding voting
securities (as defined in the Investment Company Act of 1940), of the Portfolio
with respect to the Portfolio, voting separately from any other series of the
Trust, this Agreement shall continue in full force and effect with respect to
such Portfolio from year to year thereafter so long as such continuance is
specifically approved at least annually (i) by the vote of a majority of those
Trustees of the Trust who are not parties to this Agreement or interested
persons of any such party, cast in person at a meeting called for the purpose of
voting on such approval, and (ii) by the Trustees of the Trust or by vote of a
majority of the outstanding voting securities of the Portfolio voting separately
from any other series of the Trust, provided, however, that if the shareholders
fail to approve the Agreement as provided herein, Subadviser may continue to
serve hereunder in the manner and to the extent permitted by the Investment
Company Act of 1940 and rules thereunder. The foregoing requirement that
continuance of this Agreement be "specifically approved at least annually" shall
be construed in a manner consistent with the Investment Company Act of 1940 and
the rules and regulations thereunder.
 
    This Agreement may be terminated at any time, without the payment of any
penalty by vote of a majority of the Trustees of the Trust or by a vote of a
majority of the outstanding voting securities of the
 
                                     C-5-3
<PAGE>
Portfolio on not less than 30 days nor more than 60 days written notice to
Subadviser or by Subadviser at any time without the payment of any penalty, on
90 days written notice to Adviser and the Trust; provided, however, that this
Agreement may not be terminated by Subadviser unless another subadvisory
agreement has been approved by the Trust in accordance with the Investment
Company Act of 1940, or after six months' written notice, whichever is earlier.
This Agreement shall automatically terminate in the event of its assignment (as
defined in the Investment Company Act of 1940). Any notice under this Agreement
shall be given in writing, addressed and delivered, or mailed postage prepaid,
to the other party at any office of such party.
 
    As used in this Section 11, the terms "assignment," "interested persons,"
and a "vote of a majority of the outstanding voting securities" shall have the
respective meanings set forth in the Investment Company Act of 1940 and the
rules and regulations thereunder, subject to such exemptions as may be granted
by the Securities and Exchange Commission under said Act.
 
    This Agreement will also terminate in the event that the Investment Advisory
and Management Agreement by and between the Trust on behalf of the Portfolio and
Adviser referred to in Section 1 is terminated.
 
    10.  SEVERABILITY.  If any provision of this Agreement shall be held or made
invalid by a court decision, statute, rule or otherwise, the remainder of this
Agreement shall not be affected thereby.
 
    A copy of the Declaration of Trust of the Trust is on file with the
Secretary of the Commonwealth of Massachusetts, and notice is hereby given that
nothing contained herein shall be construed to be binding upon any of the
Trustees, officers, or shareholders of the Trust individually.

officers to execute this Agreement as of         .

                             SUBADVISORY AGREEMENT
 
    This SUBADVISORY AGREEMENT is dated as of         by and between SUNAMERICA
ASSET MANAGEMENT CORP., a Delaware corporation (the "Adviser"), and MORGAN
STANLEY ASSET MANAGEMENT INC., a Delaware corporation (the "Subadviser").
 
                                  WITNESSETH:
 
    WHEREAS, the Adviser and SunAmerica Series Trust, a Massachusetts business
trust (the "Trust"), have entered into an Investment Advisory and Management
Agreement dated as of         , (the "Advisory Agreement") pursuant to which the
Adviser has agreed to provide investment management, advisory and administrative
services to the Trust; and
 
    WHEREAS, the Trust is registered under the Investment Company Act of 1940,
as amended (the "Act"), as an open-end management investment company and may
issue shares of beneficial interest in separately designated portfolios
representing separate funds with their own investment objectives, policies and
purposes; and
 
    WHEREAS, the Subadviser is engaged in the business of rendering investment
advisory services and is registered as an investment adviser under the
Investment Advisers Act of 1940, as amended; and
 
    WHEREAS, the Adviser desires to retain the Subadviser to furnish investment
advisory services to the investment portfolio or portfolios of the Trust listed
in Schedule A hereto (the "Portfolio(s)"), and the Subadviser is willing to
furnish such services;
 
    NOW, THEREFORE, it is hereby agreed between the parties hereto as follows:
 
    1.  DUTIES OF THE SUBADVISER.  The Adviser hereby engages the services of
the Subadviser in furtherance of its Investment Advisory and Management
Agreement. Pursuant to this Subadvisory Agreement and subject to the oversight
and review of the Adviser, the Subadviser will manage the investment and
reinvestment of the assets of each Portfolio listed. The Subadviser will
determine in its discretion and subject to the oversight and review of the
Adviser, the securities to be purchased or sold, will provide the Adviser with
records concerning its activities which the Adviser or the Trust is required to
maintain, and will render regular reports to the Adviser and to officers and
Trustees of the Trust concerning its discharge of the foregoing
responsibilities. The Subadviser shall discharge the foregoing responsibilities
subject to the control of the officers and the Trustees of the Trust and in
compliance with such policies as the Trustees of the Trust may from time to time
establish, and in compliance with the objectives, policies, and limitations for
the Portfolio(s) set forth in the Trust's current prospectus and statement of
additional information, and applicable laws and regulations.
 
    The Subadviser represents and warrants to the Adviser that each of the
Portfolios set forth in Schedule A will at all times be operated and managed (1)
in compliance with all applicable federal and state laws; (2) so as not to
jeopardize either the treatment of the Polaris variable annuity contracts issued
by Variable Separate Account (File No. 33-47473; hereinafter "Contracts") as
annuity contracts for purposes of the Internal Revenue Code of 1986, as amended
(the "Code"), or the eligibility of the Contracts to qualify for sale to the
public in any state where they may otherwise be sold; and (3) to minimize any
taxes and/or penalties payable by the Trust or such Portfolio. Without
limitation, the Subadviser represents and warrants the Portfolios (1)
qualification, election and maintenance of such election by each Portfolio to be
treated as a "regulated investment company" under subchapter M, chapter 1 of the
Code, and (2) compliance with (a) the provisions of the Act and rules adopted
thereunder; (b) the diversification requirements specified in the Internal
Revenue Service's regulations under Section 817(h) of the Code; (c) applicable
state insurance laws; (d) applicable federal and state securities, commodities
and banking laws; and (e) the distribution requirements necessary to avoid
payment of any
 
                                     C-6-1
<PAGE>
excise tax pursuant to Section 4982 of the Code. The Subadviser further
represents and warrants that to the extent that any statements or omissions made
in any Registration Statement for the Contracts or shares of the Trust, or any
amendment or supplement thereto, are made in reliance upon and in conformity
with information furnished by the Subadviser expressly for use therein, such
Registration Statement and any amendments or supplements thereto will, when they
become effective, conform in all material respects to the requirements of the
Securities Act of 1933 and the rules and regulations of the Commission
thereunder (the "1933 Act") and the Act and will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading.
 
    The Subadviser accepts such employment and agrees, at its own expense, to
render the services set forth herein and to provide the office space,
furnishings, equipment and personnel required by it to perform such services on
the terms and for the compensation provided in this Agreement.
 
    2.  PORTFOLIO TRANSACTIONS.  The Subadviser is authorized to select the
brokers or dealers that will execute the purchases and sales of portfolio
securities and is directed to use its best efforts to obtain the best price and
execution. In selecting such broker or dealers, the Subadviser shall consider
all relevant factors, including price (including the applicable brokerage
commission or dealer spread), the size of the order, the nature of the market
for the security or other investment, the timing of the transaction, the
reputation, experience and financial stability of the broker or dealer involved,
the quality of the service, the difficulty of execution, the execution
capabilities and operations facilities of the firm involved, and the firm's risk
in positioning a block of securities. Subject to such policies as the Trustees
may determine and consistent with Section 28(e) of the Securities Exchange Act
of 1934, as amended, the Subadviser shall not be deemed to have acted unlawfully
or to have breached any duty created by this Agreement or otherwise solely by
reason of the Subadviser's having caused a Portfolio to pay a member of an
exchange, broker or dealer an amount of commission for effecting a securities
transaction in excess of the amount of commission another member of an exchange,
broker or dealer would have charged for effecting that transaction, if the
Subadviser determines in good faith that such amount of commission was
reasonable in relation to the value of the brokerage and research services
provided by such member of an exchange, broker or dealer viewed in terms of
either that particular transaction or the Subadviser's overall responsibilities
with respect to such Portfolio and to other clients as to which the Subadviser
exercises investment discretion. The Subadviser will promptly communicate to the
Adviser and to the officers and the Trustees of the Trust such information
relating to portfolio transactions as they may reasonably request.
 
    3.  COMPENSATION OF THE SUBADVISER.  The Subadviser shall not be entitled to
receive any payment from the Trust and shall look solely and exclusively to the
Adviser for payment of all fees for the services rendered, facilities furnished
and expenses paid by it hereunder. As full compensation for the Subadviser under
this Agreement, the Adviser agrees to pay the Subadviser a fee at the annual
rates set forth in Schedule A hereto with respect to each Portfolio listed
thereon. Such fee shall be accrued daily and paid monthly as soon as practicable
after the end of each month (i.e., the applicable annual fee rate divided by 365
applied to each prior days' net assets in order to calculate the daily accrual).
For purposes of calculating the Subadviser's fee, the average daily net asset
value of a Portfolio shall be determined by taking an average of all
determinations of such net asset value during the month. If the Subadviser shall
provide its services under this Agreement for less than the whole of any month,
the foregoing compensation shall be prorated.
 
    4.  REPORTS.  The Adviser and the Subadviser agree to furnish to each other,
if applicable, current prospectuses, statements of additional information, proxy
statements, reports of shareholders, certified copies of their financial
statements, and such other information with regard to their affairs and that of
the Trust as each may reasonably request.
 
    5.  STATUS OF THE SUBADVISER.  The services of the Subadviser to the Adviser
and the Trust are not to be deemed exclusive, and the Subadviser shall be free
to render similar services to others so long as its services to the Trust are
not impaired thereby. The Subadviser shall be deemed to be an independent
 
                                     C-6-2
<PAGE>
contractor and shall, unless otherwise expressly provided or authorized, have no
authority to act for or represent the Trust in any way or otherwise be deemed an
agent of the Trust.
 
    6.  CERTAIN RECORDS.  The Subadviser hereby undertakes and agrees to
maintain, in the form and for the period required by Rule 31a-2 under the Act,
all records relating to the investments of the Portfolio(s) that are required to
be maintained by the Trust pursuant to the requirements of Rule 31a-1 of that
Act. Any records required to be maintained and preserved pursuant to the
provisions of Rule 31a-1 and Rule 31a-2 promulgated under the Act which are
prepared or maintained by the Subadviser on behalf of the Trust are the property
of the Trust and will be surrendered promptly to the Trust or the Adviser on
request.
 
    The Subadviser agrees that all accounts, books and other records maintained
and preserved by it as required hereby shall be subject at any time, and from
time to time, to such reasonable periodic, special and other examinations by the
Securities and Exchange Commission, the Trust's auditors, the Trust or any
representative of the Trust, the Adviser, or any governmental agency or other
instrumentality having regulatory authority over the Trust.
 
    7.  REFERENCE TO THE SUBADVISER.  Neither the Trust nor the Adviser or any
affiliate or agent thereof shall make reference to or use the name of the
Subadviser or any of its affiliates in any advertising or promotional materials
without the prior approval of the Subadviser, which approval shall not be
unreasonably withheld.
 
    8.  INDEMNIFICATION.  The Adviser agrees to indemnify and hold harmless the
Subadviser and its affiliates and each of its directors and officers and each
person, if any, who controls the Subadviser within the meaning of Section 15 of
the 1933 Act against any and all losses, claims, damages, liabilities or
litigation (including legal and other expenses), to which the Subadviser or its
affiliates or such directors, officers or controlling person may become subject
under the 1933 Act, under any other statute, at common law or otherwise, which
may be based upon any wrongful act or breach of this Agreement by the Adviser;
provided, however, that in no case is the Adviser's indemnity in favor of any
person deemed to protect such person against any liability to which such person
would otherwise be subject by reason of willful misfeasance, bad faith, or gross
negligence in the performance of his, her or its duties or by reasons of his,
her or its reckless disregard of obligations and duties under this Agreement.
 
    The Subadviser agrees to indemnify and hold harmless the Adviser and its
affiliates and each of its directors and officers and each person, if any, who
controls the Adviser within the meaning of Section 15 of the 1933 Act against
any and all losses, claims, damages, liabilities or litigation (including legal
and other expenses), to which the Adviser or its affiliates or such directors,
officers or controlling person may become subject under the 1933 Act, under
other statutes, at common law or otherwise, which may be based upon (i) any
wrongful act or breach of this Agreement by the Subadviser, or (ii) any failure
by the Subadviser to comply with the representations and warranties set forth in
Section 1 of this Agreement; provided, however, that in no case is the
Subadviser's indemnity in favor of any person deemed to protect such other
persons against any liability to which such person would otherwise be subject by
reasons of willful misfeasance, bad faith, or gross negligence in the
performance of his, her or its duties or by reason of his, her or its reckless
disregard of obligation and duties under this Agreement.
 
    9.  TERM OF THE AGREEMENT.  This Agreement shall continue in full force and
effect with respect to each Portfolio until the earlier of (a) two years from
the date this Agreement is approved by the Trustees, or (b) the first meeting of
the shareholders of the Portfolio of the Trust after the date hereof. If
approved at such meeting by the affirmative vote of a majority of the
outstanding voting securities (as defined in the Act), of the Portfolio with
respect to such Portfolio, voting separately from any other series of the Trust,
this Agreement shall continue in full force and effect with respect to such
Portfolio from year to year thereafter so long as such continuance is
specifically approved at least annually (i) by the vote of a majority of those
Trustees of the Trust who are not parties to this Agreement or interested
persons of any such party, cast in person at a meeting called for the purpose of
voting on such approval, and (ii) by the Trustees
 
                                     C-6-3
<PAGE>
of the Trust or by vote of a majority of the outstanding voting securities of
the Portfolio voting separately from any other series of the Trust, provided,
however, that if the shareholders fail to approve the Agreement as provided
herein, the Subadviser may continue to serve hereunder in the manner and to the
extent permitted by the Act and rules thereunder. The foregoing requirement that
continuance of this Agreement be "specifically approved at least annually" shall
be construed in a manner consistent with the Act and the rules and regulations
thereunder.
 
    With respect to each Portfolio, this Agreement may be terminated at any
time, without payment of penalty by the Portfolio or the Trust, by vote of a
majority of the Trustees, or by vote of a majority of the outstanding voting
securities (as defined in the Act) of the Portfolio, voting separately from any
other series of the Trust, or by the Adviser, on not less than 30 nor more than
60 days' written notice to the Subadviser. With respect to each Portfolio, this
Agreement may be terminated by the Subadviser at any time, without the payment
of any penalty, on 90 days' written notice to the Adviser and the Trust;
provided, however, that this Agreement may not be terminated by the Subadviser
unless another subadvisory agreement has been approved by the Trust in
accordance with the Act, or after six months' written notice, whichever is
earlier. The termination of this Agreement with respect to any Portfolio or the
addition of any Portfolio to Schedule A hereto (in the manner required by the
Act) shall not affect the continued effectiveness of this Agreement with respect
to each other Portfolio subject hereto. This Agreement shall automatically
terminate in the event of its assignment (as defined by the Act).
 
    This Agreement will also terminate in the event that the Advisory Agreement
by and between the Trust and the Adviser is terminated.
 
    10.  SEVERABILITY.  If any provision of this Agreement shall be held or made
invalid by a court decision, statute, rule or otherwise, the remainder of this
Agreement shall not be affected thereby.
 
    11.  AMENDMENTS.  This Agreement may be amended by mutual consent in
writing, but the consent of the Trust must be obtained in conformity the
requirements of the Act.
 
    12.  GOVERNING LAW.  This Agreement shall be construed in accordance with
the laws of the State of New York and the applicable provisions of the Act. To
the extent the applicable laws of the State of New York, or any of the
provisions herein, conflict with the applicable provisions of the Act, the
latter shall control.
 
    13.  PERSONAL LIABILITY.  The Declaration of the Trust establishing the
Trust (the "Declaration"), is on file in the office of the Secretary of the
Commonwealth of Massachusetts, and, in accordance with that Declaration, no
Trustee, shareholder, officer, employee or agent of the Trust shall be held to
any personal liability, nor shall resort be had to their private property for
satisfaction of any obligation or claim or otherwise in connection with the
affairs of the Trust, but the "Trust Property" only shall be liable.
 
    14.  SEPARATE SERIES.  Pursuant to the provisions of the Declaration, each
portfolio is a separate series of the Trust, and all debts, liabilities,
obligations and expenses of a particular portfolio shall be enforceable only
against the assets of that portfolio and not against the assets of any other
portfolio or of the Trust as a whole.

trust (the "Trust"), have entered into an Investment Advisory and Management
Agreement dated as of            , (the "Advisory Agreement"), pursuant to which

time to time establish as delivered in writing to the Subadviser, and in
compliance with (a) the objectives, policies, and limitations for the
Portfolio(s) set forth in the Trust's current prospectus and statement of
additional information as delivered to the Subadviser, and (b) applicable laws
and regulations.
 
    The Subadviser agrees that it will operate and manage the Portfolio set
forth in Schedule A (1) in compliance with all applicable federal and state laws
governing the Subadviser's management of the Portfolio and investments; and (2)
so as not to jeopardize either the treatment of the SunAmerica Series Trust
variable annuity contracts issued by Variable Separate Account and FS Variable
Separate Account (File Nos. 33-47473 and 33-85014, respectively; hereinafter
"Contracts") as annuity contracts for purposes of the Internal Revenue Code of
1986, as amended (the "Code"). Without limiting the foregoing, the Subadviser
agrees to manage the Portfolio in compliance with (a) the provisions of the Act
and rules adopted thereunder; (b) the diversification requirements specified in
the Internal Revenue Service's regulations under Section 817(h) of the Code; (c)
applicable state insurance laws; and (d) applicable federal and state
securities, commodities and banking laws; provided that Adviser shall provide
Subadviser with written direction as to the requirements of applicable state
insurance laws and applicable federal and state banking laws. For purposes of
the preceding sentence, disclosure in the Trust's prospectus and/or
 
                                     C-7-1
<PAGE>
statement of additional information of applicable state insurance laws and
regulations and applicable federal and state banking laws and regulations shall
constitute "written direction" thereof. The Adviser acknowledges and agrees that
the Subadviser's compliance with its obligations under this Agreement will be
based, in part, on information supplied by the Adviser, or an agent thereof, as
to each Portfolio, including but not limited to, portfolio security lot level
realized and unrealized gain/loss allocation. The Adviser agrees that all such
information will be supplied on a timely basis. The Subadviser further
represents and warrants that to the extent that any statements or omissions made
in any Registration Statement for the Contracts or shares of the Trust, or any
amendment or supplement thereto, are made in reliance upon and in conformity
with information furnished by the Subadviser expressly for use therein, such
Registration Statement and any amendments or supplements thereto will, when they
become effective, conform in all material respects to the requirements of the
Securities Act of 1933 and the rules and regulations of the Commission
thereunder (the "1933 Act") and the Act and will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading.
 
    The Subadviser accepts such employment and agrees, at its own expense, to
render the services set forth herein and to provide the office space,
furnishings, equipment and personnel required by it to perform such services on
the terms and for the compensation provided in this Agreement. The Subadviser
shall not have any responsibility for the administrative affairs of the
Portfolio, including any responsibility for the calculation of the net asset
value of the Portfolio's shares or shareholder accounting services; PROVIDED,
HOWEVER, that the Subadviser shall, as requested from time to time by the
Adviser, assist the Adviser in obtaining pricing information relating to the
Portfolio's investment securities.
 
    2.  PORTFOLIO TRANSACTIONS.  The Subadviser is responsible for decisions to
buy or sell securities and other investments of the assets of each Portfolio,
broker-dealers and futures commission merchants' selection, and negotiation of
brokerage commission and futures commission merchants' rates. As a general
matter, in executing portfolio transactions, the Subadviser may employ or deal
with such broker-dealers or futures commission merchants as may, in the
Subadviser's best judgement, provide prompt and reliable execution of the
transactions at favorable prices and reasonable commission rates. In selecting
such broker-dealers or futures commission merchants, the Subadviser shall
consider all relevant factors including price (including the applicable
brokerage commission, dealer spread or futures commission merchant rate), the
size of the order, the nature of the market for the security or other
investment, the timing of the transaction, the reputation, experience and
financial stability of the broker-dealer or futures commission merchant
involved, the quality of the service, the difficulty of execution, the execution
capabilities and operational facilities of the firm involved, and, in the case
of securities, the firm's risk in positioning a block of securities. Subject to
such policies as the Trustees may determine and consistent with Section 28(e) of
the Securities Exchange Act of 1934, as amended (the "1934 Act"), the Subadviser
shall not be deemed to have acted unlawfully or to have breached any duty
created by this Agreement or otherwise solely by reason of the Subadviser's
having caused a Portfolio to pay a member of an exchange, broker or dealer an
amount of commission for effecting a securities transaction in excess of the
amount of commission another member of an exchange, broker or dealer would have
charged for effecting that transaction, if the Subadviser determines in good
faith that such amount of commission was reasonable in relation to the value of
the brokerage and research services provided by such member of an exchange,
broker or dealer viewed in terms of either that particular transaction or the
Subadviser's overall responsibilities with respect to such Portfolio and to
other clients as to which the Subadviser exercises investment discretion. In
accordance with Section 11(a) of the 1934 Act and Rule 11a2-2(T) thereunder, and
subject to any other applicable laws and regulations including Section 17(e) of
the Act and Rule 17e-1 thereunder, the Subadviser may engage its affiliates, the
Adviser and its affiliates or any other subadviser to the Trust and its
respective affiliates, as broker-dealers or futures commission merchants to
effect portfolio transactions in securities and other investments for a
Portfolio. The Subadviser will promptly communicate to the Adviser and to the
officers and the Trustees of the Trust such information relating to portfolio
transactions as they may reasonably request. To the extent consistent with
applicable law, the Subadviser may aggregate
 
                                     C-7-2
<PAGE>
purchase or sell orders for the Portfolio with contemporaneous purchase or sell
orders of other clients of the Subadviser or its affiliated persons. In such
event, allocation of the securities so purchased or sold, as well as the
expenses incurred in the transaction, will be made by the Subadviser in the
manner the Subadviser determines to be equitable and consistent with its and its
affiliates' fiduciary obligations to the Portfolio and to such other clients.
The Adviser hereby acknowledges that such aggregation of orders may not result
in more favorable pricing or lower brokerage commissions in all instances.
 
    3.  COMPENSATION OF THE SUBADVISER.  The Subadviser shall not be entitled to
receive any payment from the Trust and shall look solely and exclusively to the
Adviser for payment of all fees for the services rendered, facilities furnished
and expenses paid by it hereunder. As full compensation for the Subadviser under
this Agreement, the Adviser agrees to pay the Subadviser a fee at the annual
rates set forth in Schedule A hereto with respect to each Portfolio listed
thereon. Such fee shall be accrued daily and paid monthly as soon as practicable
after the end of each month (i.e., the applicable annual fee rate divided by 365
applied to each prior day's net assets in order to calculate the daily accrual).
For purposes of calculating the Subadviser's fee, the average daily net asset
value of a Portfolio shall be determined by taking an average of all
determinations of such net asset value during the month. If the Subadviser shall
provide its services under this Agreement for less than the whole of any month,
the foregoing compensation shall be prorated.
 
    4.  OTHER SERVICES.  At the request of the Trust or the Adviser, the
Subadviser in its discretion may make available to the Trust, office facilities,
equipment, personnel and other services. Such office facilities, equipment,
personnel and services shall be provided for or rendered by the Subadviser and
billed to the Trust or the Adviser at the Subadviser's cost.
 
    5.  REPORTS.  The Trust, the Adviser and the Subadviser agree to furnish to
each other, if applicable, current prospectuses, statements of additional
information, proxy statements, reports of shareholders, certified copies of
their financial statements, and such other information with regard to their
affairs and that of the Trust as each may reasonably request.
 
    6.  STATUS OF THE SUBADVISER.  The services of the Subadviser to the Adviser
and the Trust are not to be deemed exclusive, and the Subadviser shall be free
to render similar services to others so long as its services to the Trust are
not impaired thereby. The Subadviser shall be deemed to be an independent
contractor and shall, unless otherwise expressly provided or authorized, have no
authority to act for or represent the Trust in any way or otherwise be deemed an
agent of the Trust.
 
    7.  CERTAIN RECORDS.  While the Subadviser is not being engaged to serve as
the Trust's official record keeper, the Subadviser nevertheless hereby
undertakes and agrees to maintain, in the form and for the period required by
Section 204 of the Advisers Act and Rule 204-2 thereunder, all records relating
to the investments of the Portfolio(s) that are required to be maintained by the
Subadviser pursuant to the requirements of Rule 204-2 under the Advisers Act.
The Subadviser will also, in connection with the purchase and sale of securities
for each Portfolio, arrange for the transmission to the custodian for the Trust
on a daily basis, such confirmation, trade tickets, and other documents and
information, that identify securities to be purchased or sold on behalf of the
Portfolio, as may be reasonably necessary to enable the custodian to perform its
administrative and recordkeeping responsibilities with respect to the Portfolio.
 
    The Subadviser agrees that all accounts, books and other records maintained
and preserved by it as required hereby shall be subject at any time, and from
time to time, to such reasonable periodic, special and other examinations by the
Securities and Exchange Commission, the Trust's auditors, the Trust or any
representative of the Trust, the Adviser, or any governmental agency or other
instrumentality having regulatory authority over the Trust.
 
    8.  REFERENCE TO THE SUBADVISER.  The Adviser covenants as follows:
 
    (a) The Adviser will (and will cause its affiliates (including the Trust)
(each an "Affiliate") to) use the name "Putnam Investment Management," "Putnam
Investments," "Putnam" or any derivation thereof
 
                                     C-7-3
<PAGE>
only for so long as this Agreement remains in effect. At such times as this
Agreement is no longer in effect, the Adviser will, and will cause each
Affiliate to, cease using any such name or any other name indicating that any
Portfolio is advised by or otherwise connected to the Subadviser.
 
    (b) It will not, and will cause its Affiliates to not, refer to the
Subadviser or any Affiliate in any sales literature or promotional material
except with the prior approval of the Subadviser. In the case of materials, such
as the portfolio's prospectus, required by law to be prepared, such approval
shall not be unreasonably withheld.
 
    (c) It will permit the Portfolios to be used as a funding vehicle only for
insurance contracts issued by SunAmerica Inc. or any of its affiliates.
 
    (d) It will not (and will cause its Affiliates to not) engage in marketing
programs (written or otherwise) directed toward Putnam Capital Manager Annuity
Contract ("PCM") which directly solicit transfers from PCM to the Adviser's
products or those of its Affiliates. For purposes of the foregoing, general
marketing efforts by SunAmerica Inc. and its affiliates shall not constitute a
direct solicitation of PCM contract holders. The Adviser will not (and will
cause its Affiliates to not) create or use marketing materials which provide
direct comparisons between PCM and the Adviser's products or those of any of its
Affiliates. The Adviser, in connection with any exchange program, will not (and
will cause its Affiliates to not) reimburse voluntarily, or enter into any
contract or policy after the date hereof providing for the reimbursement of, any
deferred sales charges to encourage the transfer of assets from PCM to the
Adviser's products or those of any Affiliate. For purposes hereof, the term
"Affiliate" shall not be construed to include agents of SunAmerica Inc. or
affiliates thereof, who are not employees of such entities.
 
    9.  LIABILITY OF THE SUBADVISER.  (a) In the absence of willful misfeasance,
bad faith, gross negligence or reckless disregard of obligations or duties
("disabling conduct") hereunder on the part of the Subadviser (and its officers,
directors, agents, employees, controlling persons, shareholders and any other
person or entity affiliated with the Subadviser) the Subadviser shall not be
subject to liability to the Trust, any shareholder of the Trust or the Adviser
for any act or omission in the course of, or connected with, rendering services
hereunder, including without limitation, any error of judgment or mistake of law
or for any loss suffered by any of them in connection with the matters to which
this Agreement relates. Except for such disabling conduct, the Adviser shall
indemnify the Subadviser (and its officers, directors, partners, agents,
employees, controlling persons, shareholders and any other person or entity
affiliated with the Subadviser) (collectively, the "Indemnified Parties") from
any liability arising from the Subadviser's conduct under this Agreement.
 
    (b) The Subadviser agrees to indemnify and hold harmless the Adviser and its
affiliates and each of its directors and officers and each person, if any, who
controls the Adviser within the meaning of Section 15 of the 1933 Act against
any and all losses, claims, damages, liabilities or litigation (including
reasonable legal and other expenses), to which the Adviser or its affiliates or
such directors, officers or controlling persons may become subject under the
1933 Act, under other statutes, at common law or otherwise, which may be based
upon (i) any wrongful act or material breach of this Agreement by the Subadviser
resulting from Subadviser's disabling conduct, or (ii) any untrue statement of a
material fact in the Trust's registration statement or omission to state a
material fact required to be stated therein or necessary to make the statement
therein not misleading, if such statement or omission was made in reliance on
information furnished by the Subadviser to use in such registration statement,
provided, however, that in no case is the Subadviser's indemnity in favor of any
person deemed to protect such other persons against any liability to which such
person would otherwise be subject by reasons of willful misfeasance, bad faith,
or gross negligence in the performance of his, her or its duties or by reason of
his, her or its reckless disregard of obligation and duties under this
Agreement.
 
    10.  PERMISSIBLE INTERESTS.  Trustees and agents of the Trust are or may be
interested in the Subadviser (or any successor thereof) as directors, partners,
officers, or shareholders, or otherwise; directors, partners,
 
                                     C-7-4
<PAGE>
officers, agents, and shareholders of the Subadviser are or may be interested in
the Trust as trustees, or otherwise; and the Subadviser (or any successor) is or
may be interested in the Trust in some manner.
 
    11.  TERM OF THE AGREEMENT.  This Agreement shall continue in full force and
effect with respect to each Portfolio until the earlier of (a) two years from
the date this Agreement is approved by the Trustees, or (b) the first meeting of
the shareholders of the Portfolio of the Trust after the date hereof. If
approved at such meeting by the affirmative vote of a majority of the
outstanding voting securities (as defined in the Act), of the Portfolio with
respect to such Portfolio, voting separately from any other series of the Trust,
this Agreement shall continue in full force and effect with respect to such
Portfolio from year to year thereafter so long as such continuance is
specifically approved at least annually (i) by the vote of a majority of those
Trustees of the Trust who are not parties to this Agreement or interested
persons of any such party, cast in person at a meeting called for the purpose of
voting on such approval, and (ii) by the Trustees of the Trust or by vote of a
majority of the outstanding voting securities of the Portfolio voting separately
from any other series of the Trust, provided, however, that if the shareholders
fail to approve the Agreement as provided herein, the Subadviser may continue to
serve hereunder in the manner and to the extent permitted by the Act and rules
thereunder. The foregoing requirement that continuance of this Agreement be
"specifically approved at least annually" shall be construed in a manner
consistent with the Act and the rules and regulations thereunder.
 
    With respect to each Portfolio, this Agreement may be terminated at any
time, without payment of a penalty by the Portfolio or the Trust, by vote of a
majority of the Trustees, or by vote of a majority of the outstanding voting
securities (as defined in the Act) of the Portfolio, voting separately from any
other series of the Trust, or by the Adviser, on not less than 30 nor more than
60 days' written notice to the Subadviser. With respect to each Portfolio, this
Agreement may be terminated by the Subadviser at any time, without the payment
of any penalty, on 60 days' written notice to the Adviser and the Trust. The
termination of this Agreement with respect to any Portfolio or the addition of
any Portfolio to Schedule A hereto (in the manner required by the Act) shall not
affect the continued effectiveness of this Agreement with respect to each other
Portfolio subject hereto. This Agreement shall automatically terminate in the
event of its assignment (as defined by the Act).
 
    This Agreement will also terminate in the event that the Advisory Agreement
by and between the Trust and the Adviser is terminated.
 
    12.  SEVERABILITY.  If any provision of this Agreement shall be held or made
invalid by a court decision, statute, rule or otherwise, the remainder of this
Agreement shall not be affected thereby.
 
    13.  AMENDMENTS.  This Agreement may be amended by mutual consent in
writing, but the consent of the Trust must be obtained in conformity with the
requirements of the Act.
 
    14.  GOVERNING LAW.  This Agreement shall be construed in accordance with
the laws of the State of New York and the applicable provisions of the Act. To
the extent the applicable laws of the State of New York, or any of the
provisions herein, conflict with the applicable provisions of the Act, the
latter shall control.
 
    15.  PERSONAL LIABILITY.  The Declaration of the Trust establishing the
Trust (the "Declaration"), is on file in the office of the Secretary of the
Commonwealth of Massachusetts, and, in accordance with that Declaration, no
Trustee, shareholder, officer, employee or agent of the Trust shall be held to
any personal liability, nor shall resort be had to their private property for
satisfaction of any obligation or claim or otherwise in connection with the
affairs of the Trust, but the "Trust Property" only shall be liable.
 
    16.  SEPARATE SERIES.  Pursuant to the provisions of the Declaration, each
Portfolio is a separate series of the Trust, and all debts, liabilities,
obligations and expenses of a particular Portfolio shall be enforceable only
against the assets of that Portfolio and not against the assets of any other
Portfolio or of the Trust as a whole.

                                    FORM OF
                             SUBADVISORY AGREEMENT
 
    This SUBADVISORY AGREEMENT is dated as of                 , by and between
SUNAMERICA ASSET MANAGEMENT CORP., a Delaware corporation (the "Adviser"), and
MASSACHUSETTS FINANCIAL SERVICES COMPANY, a Delaware corporation (the
"Subadviser").
 
                                  WITNESSETH:
 
    WHEREAS, the Adviser and SunAmerica Series Trust, a Massachusetts business
trust (the "Trust"), have entered into an Investment Advisory and Management
Agreement dated as of                  , (the "Advisory Agreement"), pursuant to
which the Adviser has agreed to provide investment management, advisory and
administrative services to the Trust; and
 
    WHEREAS, the Trust is registered under the Investment Company Act of 1940,
as amended (the "Act"), as an open-end management investment company and may
issue shares of beneficial interest, par value $.01 per share, in separately
designated portfolios representing separate funds with their own investment
objectives, policies and purposes; and
 
    WHEREAS, the Subadviser is engaged in the business of rendering investment
advisory services and is registered as an investment adviser under the
Investment Advisers Act of 1940, as amended; and
 
    WHEREAS, the Adviser desires to retain the Subadviser to furnish investment
advisory services to the investment portfolio or portfolios of the Trust listed
on Schedule A attached hereto (the "Portfolio(s)"), and the Subadviser is
willing to furnish such services;
 
    NOW, THEREFORE, it is hereby agreed between the parties hereto as follows:
 
    1.  DUTIES OF THE SUBADVISER.  The Adviser hereby engages the services of
the Subadviser in furtherance of its Investment Advisory and Management
Agreement with the Trust. Pursuant to this Subadvisory Agreement and subject to
the oversight and review of the Adviser, the Subadviser will manage the
investment and reinvestment of the assets of each Portfolio listed on Schedule A
attached hereto. The Subadviser will determine in its discretion and subject to
the oversight and review of the Adviser, the securities to be purchased or sold,
will provide the Adviser with records concerning its activities which the
Adviser or the Trust is required to maintain, and will render regular reports to
the Adviser and to officers and Trustees of the Trust concerning its discharge
of the foregoing responsibilities. The Subadviser shall discharge the foregoing
responsibilities subject to the control of the officers and the Trustees of the
Trust and in compliance with such policies as the Trustees of the Trust may from
time to time establish, and in compliance with (a) the objectives, policies, and
limitations for the Portfolio(s) set forth in the Trust's current prospectus and
statement of additional information, and (b) applicable laws and regulations.
 
    The Subadviser represents and warrants to the Adviser that each of the
Portfolios set forth in Schedule A will at all times be operated and managed (1)
in compliance with all applicable federal and state laws governing its
operations and investments; (2) so as not to jeopardize either the treatment of
the variable annuity contracts issued by a SunAmerica life insurance company
(hereinafter "Contracts") as annuity contracts for purposes of the Internal
Revenue Code of 1986, as amended (the "Code"), or the eligibility of the
Contracts to qualify for sale to the public in any state where they may
otherwise be sold; and (3) to minimize any taxes and/or penalties payable by the
Trust or such Portfolio. Without limiting the foregoing, the Subadviser
represents and warrants (1) qualification, election and maintenance of such
election by each Portfolio to be treated as a "regulated investment company"
under subchapter M, chapter 1 of the Code, and (2) compliance with (a) the
provisions of the Act and rules adopted thereunder; (b) the diversification
requirements specified in the Internal Revenue Service's regulations under
Section 817(h) of the Code; (c) applicable state insurance laws; (d) applicable
federal and state securities, commodities and banking laws; and (e) the
distribution requirements necessary to avoid payment of any excise tax pursuant
to Section 4982 of the Code. The Subadviser further represents and warrants that
to
 
                                      M-1
<PAGE>
the extent that any statements or omissions made in any Registration Statement
for the Contracts or shares of the Trust, or any amendment or supplement
thereto, are made in reliance upon and in conformity with information furnished
by the Subadviser expressly for use therein, such Registration Statement and any
amendments or supplements thereto will, when they become effective, conform in
all material respects to the requirements of the Securities Act of 1933 and the
rules and regulations of the Commission thereunder (the "1933 Act") and the Act
and will not contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the
statements therein not misleading.
 
    The Subadviser accepts such employment and agrees, at its own expense, to
render the services set forth herein and to provide the office space,
furnishings, equipment and personnel required by it to perform such services on
the terms and for the compensation provided in this Agreement.
 
    2.  PORTFOLIO TRANSACTIONS.  The Subadviser is responsible for decisions to
buy or sell securities and other investments of the assets of each Portfolio,
broker-dealers and futures commission merchants' selection, and negotiation of
brokerage commission and futures commission merchants' rates. As a general
matter, in executing portfolio transactions, the Subadviser may employ or deal
with such broker-dealers or futures commission merchants as may, in the
Subadviser's best judgement, provide prompt and reliable execution of the
transactions at favorable prices and reasonable commission rates. In selecting
such broker-dealers or futures commission merchants, the Subadviser shall
consider all relevant factors including price (including the applicable
brokerage commission, dealer spread or futures commission merchant rate), the
size of the order, the nature of the market for the security or other
investment, the timing of the transaction, the reputation, experience and
financial stability of the broker-dealer or futures commission merchant
involved, the quality of the service, the difficulty of execution, the execution
capabilities and operational facilities of the firm involved, and, in the case
of securities, the firm's risk in positioning a block of securities. Subject to
such policies as the Trustees may determine and consistent with Section 28(e) of
the Securities Exchange Act of 1934, as amended (the "1934 Act"), the Subadviser
shall not be deemed to have acted unlawfully or to have breached any duty
created by this Agreement or otherwise solely by reason of the Subadviser's
having caused a Portfolio to pay a member of an exchange, broker or dealer an
amount of commission for effecting a securities transaction in excess of the
amount of commission another member of an exchange, broker or dealer would have
charged for effecting that transaction, if the Subadviser determines in good
faith that such amount of commission was reasonable in relation to the value of
the brokerage and research services provided by such member of an exchange,
broker or dealer viewed in terms of either that particular transaction or the
Subadviser's overall responsibilities with respect to such Portfolio and to
other clients as to which the Subadviser exercises investment discretion. In
accordance with Section 11(a) of the 1934 Act and Rule 11a2-2(T) thereunder, and
subject to any other applicable laws and regulations including Section 17(e) of
the Act and Rule 17e-1 thereunder, the Subadviser may engage its affiliates, the
Adviser and its affiliates or any other subadviser to the Trust and its
respective affiliates, as broker-dealers or futures commission merchants to
effect portfolio transactions in securities and other investments for a
Portfolio. The Subadviser will promptly communicate to the Adviser and to the
officers and the Trustees of the Trust such information relating to portfolio
transactions as they may reasonably request.
 
    3.  COMPENSATION OF THE SUBADVISER.  The Subadviser shall not be entitled to
receive any payment from the Trust and shall look solely and exclusively to the
Adviser for payment of all fees for the services rendered, facilities furnished
and expenses paid by it hereunder. As full compensation for the Subadviser under
this Agreement, the Adviser agrees to pay the Subadviser a fee at the annual
rates set forth in Schedule A hereto with respect to each Portfolio listed
thereon. Such fee shall be accrued daily and paid monthly as soon as practicable
after the end of each month (i.e., the applicable annual fee rate divided by 365
applied to each prior day's net assets in order to calculate the daily accrual).
For purposes of calculating the Subadviser's fee, the average daily net asset
value of a Portfolio shall be determined by taking an average of all
determinations of such net asset value during the month. If the Subadviser shall
provide its services under this Agreement for less than the whole of any month,
the foregoing compensation shall be prorated.

    4.  OTHER SERVICES.  At the request of the Trust or the Adviser, the
Subadviser in its discretion may make available to the Trust, office facilities,
equipment, personnel and other services. Such office facilities, equipment,
personnel and services shall be provided for or rendered by the Subadviser and
billed to the Trust or the Adviser at the Subadviser's cost.
 
    5.  REPORTS.  The Trust, the Adviser and the Subadviser agree to furnish to
each other, if applicable, current prospectuses, statements of additional
information, proxy statements, reports of shareholders, certified copies of
their financial statements, and such other information with regard to their
affairs and that of the Trust as each may reasonably request.
 
    6.  STATUS OF THE SUBADVISER.  The services of the Subadviser to the Adviser
and the Trust are not to be deemed exclusive, and the Subadviser shall be free
to render similar services to others so long as its services to the Trust are
not impaired thereby. The Subadviser shall be deemed to be an independent
contractor and shall, unless otherwise expressly provided or authorized, have no
authority to act for or represent the Trust in any way or otherwise be deemed an
agent of the Trust.
 
    7.  CERTAIN RECORDS.  The Subadviser hereby undertakes and agrees to
maintain, in the form and for the period required by Rule 31a-2 under the Act,
all records relating to the investments of the Portfolio(s) that are required to
be maintained by the Trust pursuant to the requirements of Rule 31a-1 of that
Act. Any records required to be maintained and preserved pursuant to the
provisions of Rule 31a-1 and Rule 31a-2 promulgated under the Act which are
prepared or maintained by the Subadviser on behalf of the Trust are the property
of the Trust and will be surrendered promptly to the Trust or the Adviser on
request.
 
    The Subadviser agrees that all accounts, books and other records maintained
and preserved by it as required hereby shall be subject at any time, and from
time to time, to such reasonable periodic, special and other examinations by the
Securities and Exchange Commission, the Trust's auditors, the Trust or any
representative of the Trust, the Adviser, or any governmental agency or other
instrumentality having regulatory authority over the Trust.
 
    8.  REFERENCE TO THE SUBADVISER.  Neither the Trust nor the Adviser or any
affiliate or agent thereof shall make reference to or use the name of the
Subadviser or any of its affiliates in any advertising or promotional materials
without the prior approval of the Subadviser, which approval shall not be
unreasonably withheld.
 
    9.  LIABILITY OF THE SUBADVISER.  (a) In the absence of willful misfeasance,
bad faith, gross negligence or reckless disregard of obligations or duties
("disabling conduct") hereunder on the part of the Subadviser (and its officers,
directors, agents, employees, controlling persons, shareholders and any other
person or entity affiliated with the Subadviser) the Subadviser shall not be
subject to liability to the Trust or to any shareholder of the Trust for any act
or omission in the course of, or connected with, rendering services hereunder,
including without limitation, any error of judgment or mistake of law or for any
loss suffered by any of them in connection with the matters to which this
Agreement relates, except to the extent specified in Section 36(b) of the Act
concerning loss resulting from a breach of fiduciary duty with respect to the
receipt of compensation for services. Except for such disabling conduct, the
Adviser shall indemnify the Subadviser (and its officers, directors, partners,
agents, employees, controlling persons, shareholders and any other person or
entity affiliated with the Subadviser) (collectively, the "Indemnified Parties")
from any liability arising from the Subadviser's conduct under this Agreement.
Subadviser hereby indemnifies, defends and protects Adviser and holds Adviser
harmless, from and against any and all liability arising out of Subadviser's
disabling conduct.
 
    (b) The Subadviser agrees to indemnify and hold harmless the Adviser and its
affiliates and each of its directors and officers and each person, if any, who
controls the Adviser within the meaning of Section 15 of the 1933 Act against
any and all losses, claims, damages, liabilities or litigation (including legal
and other expenses), to which the Adviser or its affiliates or such directors,
officers or controlling person may become subject under the 1933 Act, under
other statutes, at common law or otherwise, which may be based upon (i) any
wrongful act or breach of this Agreement by the Subadviser, or (ii) any failure
by the
 
                                      M-3
<PAGE>
Subadviser to comply with the representations and warranties set forth in
Section 1 of this Agreement; provided, however, that in no case is the
Subadviser's indemnity in favor of any person deemed to protect such other
persons against any liability to which such person would otherwise be subject by
reasons of willful misfeasance, bad faith, or gross negligence in the
performance of his, her or its duties or by reason of his, her or its reckless
disregard of obligation and duties under this Agreement.
 
    10.  PERMISSIBLE INTERESTS.  Trustees and agents of the Trust are or may be
interested in the Subadviser (or any successor thereof) as directors, partners,
officers, or shareholders, or otherwise; directors, partners, officers, agents,
and shareholders of the Subadviser are or may be interested in the Trust as
trustees, or otherwise; and the Subadviser (or any successor) is or may be
interested in the Trust in some manner.
 
    11.  TERM OF THE AGREEMENT.  This Agreement shall continue in full force and
effect with respect to each Portfolio until two years from the date hereof, and
from year to year thereafter so long as such continuance is specifically
approved at least annually (i) by the vote of a majority of those Trustees of
the Trust who are not parties to this Agreement or interested persons of any
such party, cast in person at a meeting called for the purpose of voting on such
approval, and (ii) by the Trustees of the Trust or by vote of a majority of the
outstanding voting securities of the Portfolio voting separately from any other
series of the Trust.
 
    With respect to each Portfolio, this Agreement may be terminated at any
time, without payment of a penalty by the Portfolio or the Trust, by vote of a
majority of the Trustees, or by vote of a majority of the outstanding voting
securities (as defined in the Act) of the Portfolio, voting separately from any
other series of the Trust, or by the Adviser, on not less than 30 nor more than
60 days' written notice to the Subadviser. With respect to each Portfolio, this
Agreement may be terminated by the Subadviser at any time, without the payment
of any penalty, on 90 days' written notice to the Adviser and the Trust;
provided, however, that this Agreement may not be terminated by the Subadviser
unless another subadvisory agreement has been approved by the Trust in
accordance with the Act, or after six months' written notice, whichever is
earlier. The termination of this Agreement with respect to any Portfolio or the
addition of any Portfolio to Schedule A hereto (in the manner required by the
Act) shall not affect the continued effectiveness of this Agreement with respect
to each other Portfolio subject hereto. This Agreement shall automatically
terminate in the event of its assignment (as defined by the Act).
 
    This Agreement will also terminate in the event that the Advisory Agreement
by and between the Trust and the Adviser is terminated.
 
    12.  SEVERABILITY.  If any provision of this Agreement shall be held or made
invalid by a court decision, statute, rule or otherwise, the remainder of this
Agreement shall not be affected thereby.
 
    13.  AMENDMENTS.  This Agreement may be amended by mutual consent in
writing, but the consent of the Trust must be obtained in conformity with the
requirements of the Act.
 
    14.  GOVERNING LAW.  This Agreement shall be construed in accordance with
the laws of the State of New York and the applicable provisions of the Act. To
the extent the applicable laws of the State of New York, or any of the
provisions herein, conflict with the applicable provisions of the Act, the
latter shall control.
 
    15.  PERSONAL LIABILITY.  The Declaration of the Trust establishing the
Trust (the "Declaration"), is on file in the office of the Secretary of the
Commonwealth of Massachusetts, and, in accordance with that Declaration, no
Trustee, shareholder, officer, employee or agent of the Trust shall be held to
any personal liability, nor shall resort be had to their private property for
satisfaction of any obligation or claim or otherwise in connection with the
affairs of the Trust, but the "Trust Property" only shall be liable.
 
    16.  SEPARATE SERIES.  Pursuant to the provisions of the Declaration, each
Portfolio is a separate series of the Trust, and all debts, liabilities,
obligations and expenses of a particular Portfolio shall be enforceable only
against the assets of that Portfolio and not against the assets of any other
Portfolio or of the Trust as a whole.
