SUNAMERICA INC.

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 there are no
organizational changes planned which would affect services provided to the
Trust. As a result of this transaction, it is necessary for the shareholders of
Anchor Series Trust, which underlies your variable annuity and 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 are set forth in the attached Notice of Special Meeting of
Shareholders. We also included 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 votes, 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 you. 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 any 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]

                                 IMPORTANT NEWS
                      FOR ANCHOR 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.
 
                          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 TRUSTEES 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 Anchor Series 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. The new advisory agreement 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.  The Anchor Series Trust subadvisory agreement provides that it terminates
    automatically if the advisory agreement between Anchor Series Trust and
    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. The new subadvisory agreement is
    identical in all material respects to the existing subadvisory agreement.
 
Q.  WHAT ELSE AM I BEING ASKED TO VOTE ON?
 
A.  You are being asked to re-elect a Board of Trustees that is the same as the
    current Board of Trustees. Also, in order to save the expense of a
    subsequent meeting, you are being asked to vote to change certain of your
    Trust's fundamental investment restrictions. Finally, you are being asked to
    vote to ratify the Board's selection of the Trust's independent accountants.
<PAGE>
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 Board 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 TRUST'S BOARD RECOMMEND THAT I VOTE?
 
A.  After careful consideration, the Board of Trustees 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 may be available to 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 INSTRUCTION CARD(S)
                                   PROMPTLY.

6. To transact such other business as may properly come before the Meeting  All Portfolios
or any adjournments thereof.
</TABLE>
 
    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, First SunAmerica, Anchor
National, [Phoenix, Presidential] 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. In connection with the
solicitation of voting instructions, the 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 holders to
input a twelve digit control number which is located on each voting instructions
card. Subsequent to inputting this number, 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 $30,000 and, as
stated above, will not be borne by the Trust or the Portfolios.
 
                                       2
<PAGE>
    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 permitted 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 any of the methods outlined above, 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.

both individually and as a group, owned less than 1% of the outstanding shares
of the Trust and each Portfolio as of the Record Date.
 
    Each Company, as the holder of record shares of each Portfolio, is required
to "pass through" to its contract owners the right to vote shares of each
Portfolio. The Trust expects that each Company will vote 100% of the shares of
the Portfolios held by its respective separate accounts. The 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 the Proposals. Unmarked
voting instructions from contract owners will be voted in favor of the
Proposals. Each Company, as record shareholder of each of the Portfolios, may
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 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.

                           ELECTION OF FOUR TRUSTEES
                                 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.
 
    The current Board of Trustees satisfies the first condition of Section
15(f), as 75% of the Trustees are not interested persons of SunAmerica, AIG or
the Subadviser ("Disinterested Trustees"). Moreover, 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 less than
75% of the Board to consist of Disinterested Trustees.
 
    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).

REMUNERATION OF TRUSTEES AND OFFICERS
 
    Officers of the Trust receive no direct remuneration in such capacity from
the Trust or the Portfolios. Each of the Disinterested Trustees is entitled to
compensation from the Trust consisting of an annual fee of $20,000 in addition
to being reimbursed for out-of-pocket expenses in connection with attendance at
meetings of the Board. In addition, Mr. Eisenstat receives an aggregate of
$2,000 in annual compensation for serving as Chairman of the Boards of the Trust
and SAMF. In addition, each Disinterested Trustee also serves on the Audit
Committee of the Board. Each member of the Audit Committee receives an aggregate
of $5,000 in annual compensation for serving on the Audit Committees of the
Trust and SAMF. The Boards of the Trust and SAMF have adopted the SunAmerica
Disinterested Trustees' and Directors' Retirement Plan (the "Retirement Plan")
effective January 1, 1993 for the Disinterested Trustees. The Retirement Plan
provides generally that if a Disinterested Trustee who has at least 10 years of
consecutive service as a Disinterested Trustee of either the Trust or SAMF (an
"Eligible Trustee") retires after reaching age 60 but before age 70 or dies
while a Trustee, such person will be eligible to receive a retirement or death
benefit from each SunAmerica mutual fund with respect to which he or she is an
Eligible Trustee. As

of each birthday, prior to the 70th birthday, each Eligible Trustee will be
credited with an amount equal to (i) 50% of his or her regular fees (excluding
committee fees) for services as a Disinterested Trustee of each SunAmerica
mutual fund for the calendar year in which such birthday occurs, plus (ii) 8.5%
of any amounts credited under clause (i) during prior years. An Eligible Trustee
may receive any benefits payable under the Retirement Plan, at his or her
election, either in one lump sum or in up to fifteen annual installments. The
following table sets forth information summarizing the compensation of each of
the Disinterested Trustees for his services as Trustee for the most recently

 THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" EACH
                      OF THE NOMINEES UNDER PROPOSAL NO. 1
                            ------------------------
 
 APPROVAL OR DISAPPROVAL OF A NEW INVESTMENT ADVISORY AND MANAGEMENT AGREEMENT
             BETWEEN ANCHOR AND SAAMCO ON BEHALF OF EACH PORTFOLIO
                                 PROPOSAL NO. 2
 
    The Board of Trustees of Anchor is submitting for approval by the
shareholders of each Portfolio, a new investment advisory and management
agreement (a "New Advisory Agreement") between Anchor, on behalf of each
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
Portfolio (the "Existing Advisory Agreement").
 
    As required by the 1940 Act, the 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
Agreement, and, consequently, its termination. Accordingly, a New Advisory
Agreement with SAAMCo to take effect upon the Closing is being proposed for
approval by the shareholders of each Portfolio, even though the agreements will
be identical in all material respects to, and essentially a continuation of, the
Existing Advisory Agreement with SAAMCo. (The Existing Advisory Agreement and
New Advisory Agreement are sometimes collectively referred to as the "Advisory
Agreements.")
 
    In addition, the current subadvisory agreement (the "Existing Subadvisory
Agreement") between SAAMCo and the Subadviser to each Portfolio provides for
termination upon termination of the Existing Advisory Agreement. Accordingly,
the Existing Subadvisory Agreement will also terminate upon the Closing of the
Merger. A new subadvisory agreement is therefore also being separately proposed
for approval by shareholders and is described in Proposal No. 3.
 
    Although it is anticipated that the Closing will take place subsequent to
the shareholders' consideration and vote upon Proposal No. 2 regarding the New
Advisory Agreement and Proposal No. 3 regarding a New Subadvisory Agreement, it
is possible that due to unforeseen delays in the holding of the Meeting, the
 
                                       8
<PAGE>
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 Subadviser 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 Subadviser, respectively, only
if the shareholders approve, respectively, Proposal Nos. 2 and 3. There can be
no assurance that the SEC will grant the requested Exemptive Order.
 
APPROVAL OF THE NEW ADVISORY AGREEMENT
 
    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, a new subadvisory agreement between
SAAMCo and the Subadviser (the "New Subadvisory Agreement" and together with the
New Advisory Agreements, the "New Agreements"), to become effective as of the
Closing. A description of the New Advisory Agreement 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 Agreement,
including advisory fees, is identical in all material respects to the Existing
Advisory Agreement. The New Advisory Agreement differs from the Existing
Advisory Agreement only with respect to the effective date.
 
    At a meeting held on October 20, 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 Portfolios and no reduction 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 the 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 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
 
    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 Portfolio and its shareholders to enter into the New
Advisory Agreement and to recommend approval of the New Advisory Agreement by
shareholders.

INFORMATION ABOUT THE NEW ADVISORY AGREEMENT
 
    As stated above, the form of the New Advisory Agreement is annexed to this
Proxy Statement as Exhibit A.
 
    The New Advisory Agreement is identical in all material respects to the
Existing Advisory Agreement, and provides that SAAMCo shall act as investment
adviser, manage the investments, administer the business affairs, provide office
space and other facilities and equipment, provide clerical, bookkeeping and
administrative services, and permit any of SAAMCo's officers or employees to
serve without compensation as Trustees or officers. Under the Advisory
Agreements, the Trust agrees to assume and pay certain charges and expenses of
its operations, including: direct charges relating to the purchase and sale of
portfolio securities, interest charges, fees and expenses of independent legal
counsel and independent accountants, expenses of registering and qualifying
shares for sale, expenses of printing and distributing reports, notices and
proxy materials to shareholders, fees and disbursements of transfer or dividend
disbursing agents and registrars, custodians, expenses of disbursing dividends
and distributions, fees and expenses of Trustees who are not employees of
SAAMCo, Wellington or their affiliates, membership dues in the Investment
Company Institute or any similar organization, all taxes and fees to federal,
state or other governmental agencies, costs of calculating net asset value, and
miscellaneous expenses.
 
    Each Portfolio pays its actual expenses for custodian services and a portion
of the custodian's costs determined by the ratio of portfolio assets to the
total assets of the Trust, brokerage commissions or transaction costs, and
registration fees. Subject to supervision of the Board of Trustees, fees for
independent accountants, legal counsel, costs of reports of notices to
shareholders will be allocated based on the relative net assets of each
Portfolio. With respect to audit or legal fees clearly attributable to one
Portfolio, they will be assessed, subject to review by the Board of Trustees,
against that Portfolio.
 
    The Advisory Agreements provide that as compensation for its services,
SAAMCo will receive a fee from the Trust, computed daily and payable monthly,
based on the net assets of each Portfolio. As of [date], SAAMCo unilaterally
agreed to a fee reduction (the "Fee Reduction") with respect to each Portfolio
except the Natural Resources Portfolio by including breakpoints in the fee rate.
The New Advisory Agreement contains a fee schedule that reflects the actual fee
rates (including breakpoints, if applicable) that are currently in effect
pursuant to the Fee Reduction. The following table sets forth the contractual
rate of the advisory fee under the Existing Advisory Agreement, the actual rate
of advisory fee payable by each Portfolio under the Fee Reduction, the rate of
advisory fee payable under the New Advisory Agreement, and the total advisory
fees earned by SAAMCo from each Portfolio pursuant to the Existing Advisory
Agreement (subject to the Fee Reduction, if applicable) for the fiscal year
ended December 31, 1997. The Subadviser is compensated by SAAMCo out of its
advisory fees.

             APPROVAL OR DISAPPROVAL OF NEW SUBADVISORY AGREEMENTS
                                 PROPOSAL NO. 3
 
    The Board of Trustees of Anchor is submitting for approval by the
shareholders of each Portfolio, a New Subadvisory Agreement between SAAMCo and
the Subadviser, the terms of which are identical in all material respects to the
Existing Subadvisory Agreement.
 
    As described above in Proposal No. 2, the Existing Subadvisory Agreement
will terminate automatically upon termination of the Existing Advisory
Agreement. Accordingly, a New Subadvisory Agreement between SAAMCo and the
Subadviser to take effect upon the Closing is being proposed for approval by the
shareholders of each Portfolio, even though the agreements will be identical in
all material respects to, and essentially a continuation of, the Existing
Subadvisory Agreement between SAAMCo and the Subadviser. (The Existing
Subadvisory Agreement and the New Subadvisory Agreement are hereinafter
sometimes collectively referred to as the "Subadvisory Agreements.")
 
APPROVAL OF THE NEW SUBADVISORY AGREEMENT
 
    As described below, the Trustees are proposing that shareholders of each
Portfolio approve a New Subadvisory Agreement between SAAMCo and each
Portfolio's Subadviser, to become effective as of the Closing. A description of
the New Subadvisory Agreement and the services to be provided by the
 
                                       13
<PAGE>
Subadviser is set forth below. This description is qualified in its entirety by
reference to the New Subadvisory Agreement attached to this Proxy Statement as
Exhibit C.
 
    As more fully described below, the proposed New Subadvisory Agreement,
including subadvisory fees, is identical in all material respects to the
Existing Subadvisory Agreement. The New Subadvisory Agreement differs from the
Existing Subadvisory Agreement only with respect to the effective dates.
 
    At a meeting held on October 20, 1998, the Trustees of the Trust, including
all the Disinterested Trustees, unanimously approved the New Subadvisory
Agreement. In determining to approve the New Subadvisory Agreement, the Trustees
evaluated the factors they deemed relevant with respect to each Portfolio,
including the factors described in Proposal No. 2 with respect to the New
Advisory Agreement. 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 the Subadviser, since the Subadviser is
independent of SAAMCo.
 
RECOMMENDATION OF THE BOARD
 
    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 Portfolio and its shareholders to enter into the New
Subadvisory Agreement and to recommend approval of the New Subadvisory Agreement
by shareholders.

             APPROVAL OR DISAPPROVAL OF PROPOSALS TO CHANGE CERTAIN
                      FUNDAMENTAL INVESTMENT RESTRICTIONS
 
                               PROPOSAL NO. 4(a)
            PROPOSAL TO AMEND THE FUNDAMENTAL INVESTMENT RESTRICTION
            RELATING TO CONCENTRATION OF INVESTMENTS IN AN INDUSTRY
                       (NATURAL RESOURCES PORTFOLIO ONLY)
 
    The Board of Trustees of Anchor is submitting for approval by shareholders
of the Natural Resources Portfolio, a proposal to amend the fundamental
investment restriction relating to concentration of investments in the
securities of companies in gold-related industries. Currently, the Natural
Resources Portfolio is required to invest more than 25% of its total assets in
securities of companies in gold-related industries. The Subadviser has proposed
deleting this requirement to allow the Natural Resources Portfolio greater
flexibility in investing its assets. The Board approved this proposal with
respect to the Natural Resources Portfolio at a meeting held on October 20,
1998.
 
    For the reasons described below, the Trustees recommend that shareholders
approve the proposed amendment. Fundamental restrictions may be changed only
with shareholder approval.
 
    If the proposed change to the Natural Resources Portfolio's investment
restrictions is approved by shareholders at the Meeting, the Trust's prospectus
and statement of additional information will be revised as appropriate to
reflect the change. This Proposal No. 4(a) will not result in a change to the
investment objective of the Natural Resources Portfolio.

PROPOSED CHANGE
 
    Amending a portion of the Portfolio's fundamental investment restriction
relating to concentration of investments, by deleting the bracketed and
underscored limitation relating to concentration of investments in the
securities of companies in gold-related industries, as follows:
 
    The Portfolio may not purchase any security (other than obligations of the
U.S. Government, its agencies or instrumentalities) if as a result more than 5%
of the Portfolio's total assets (taken at current value) would then be invested
in securities of a single issuer, or more than 25% of its total assets (taken at
current value) would then be invested in a single industry with the exception of
 . . . [the Natural Resources Portfolio which intends to concentrate its
investments in the securities of companies in gold-related industries].
 
    The portion of the existing fundamental restriction that is not bracketed
and underscored above will not be affected by the adoption of this Proposal No.
4(a).
 
DISCUSSION
 
    Under the 1940 Act an investment company can deviate from or change its
concentration policy only with shareholder approval. The staff of the SEC has
taken the position that investment of more than 25% of a Portfolio's assets in
any one industry represents concentration. In order to allow for greater
flexibility in the investment of the assets of the Natural Resources Portfolio,
based on information provided by the Subadviser, the Board believes that the
Portfolio's fundamental restriction on concentration of investments in the
securities of companies in gold-related industries should be eliminated.
 
    The Subadviser has proposed that the fundamental policy relating to
investment in securities of companies in gold-related industries be eliminated.
The Subadviser believes that several developments have contributed to reduce the
expected returns from gold-related stocks, and to reduce gold's appeal as an
inflation hedge in general. Among these developments are the continuing removal
of the gold standard for currency reserves in most of the world, and more
recently, large sales of gold reserves by central banks. Moreover, the
Subadviser believes that the Portfolio's historical investment in gold-related
industries reflects an over-weighting versus the Portfolio's peer group of
funds, and has caused the Portfolio to suffer a competitive disadvantage in
terms of relative returns. Of course, past performance is not predictive of
future returns. The Subadviser informed the Board that it actively follows the
gold sector and its Natural Resources portfolio management team is likely to
invest in that sector going forward on behalf of the Portfolio, but in a smaller
weighting. The Subadviser believes that an increase in flexibility to maintain a
diversified approach to natural resources investing is potentially beneficial
for the Portfolio's shareholders.

                       PROPOSAL CHANGING THE FUNDAMENTAL
            INVESTMENT RESTRICTION WITH RESPECT TO EACH PORTFOLIO'S
                  ABILITY TO ENGAGE IN BORROWING TRANSACTIONS
                                (ALL PORTFOLIOS)
 
    The Board of Trustees of Anchor 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 20, 1998.
 
    For the reasons described below, Trustees recommends that shareholders
approve the proposed amendment. Fundamental investment restrictions may be
changed only with shareholder approval.
 
    If the proposed change to the Portfolios' fundamental investment restriction
is approved by shareholders at the Meeting, the Trust's prospectus and statement
of additional information will be revised as
 
                                       17
<PAGE>
appropriate to reflect the changes. This Proposal No. 4(b) will not result in a
change to the investment objective of any Portfolio.
 
PROPOSED CHANGE
 
    Amending a portion of each Portfolio's fundamental investment restriction
relating to borrowing transactions by, in each case, deleting the limitation
relating to borrowing "from non-banks," as follows:

                Each Portfolio may not:                                   Each Portfolio may not:
 
Borrow money or pledge Portfolio assets except for        Borrow money or pledge Portfolio assets except for
temporary or emergency purposes . . . No more than 5% of  temporary or emergency purposes . . . (Neither the
the assets of each Portfolio may be borrowed from         deposit . . .)
non-banks. (Neither the deposit . . .)
</TABLE>
 
    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
 
                                       18
<PAGE>
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 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. 4(c)). 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.

    For the reasons described below, the Trustees recommend that shareholders
approve the proposed amendment. Fundamental investment restrictions may be
changed only with shareholder approval.
 
    If the proposed change to the Portfolios' fundamental investment restriction
is approved by shareholders at the Meeting, the Trust's prospectus and statement
of additional information will be revised as appropriate to reflect the changes.
This Proposal No. 4(c) will not result in a change to the investment objective
of any Portfolio.

PROPOSED CHANGE
 
    Amending each Portfolio's fundamental investment restriction relating to
lending transactions by, in each case, adding a clause (which is bolded for ease
of reference) permitting interfund lending, as follows:

                                                          SUNAMERICA COMPLEX. . . .
</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. 4(c). 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. 4
 
    If one or more of the changes contemplated by Proposal No. 4 are not
approved by the shareholders of one of the applicable Portfolios, the related
existing fundamental restriction(s) of that Portfolio will continue in effect
for that Portfolio. Disapproval of all or part of Proposal No. 4 by shareholders
of one Portfolio will not affect any approvals of Proposal No. 4 that are
obtained with respect to any other Portfolio.

                              GENERAL INFORMATION
 
SHAREHOLDER PROPOSALS AND SHAREHOLDER MEETINGS
 
    Notwithstanding the approval or disapproval of the proposals described
above, as in the past, the Board does not intend to hold annual meetings of
shareholders of the Trust. The Board will call meetings of shareholders as may
be required under the 1940 Act (such as to approve a new investment advisory
agreement for the Trust) or as they may determine in their discretion. The Board
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 Declaration of
Trust requires the Board to call a meeting of shareholders of the Trust when
requested to do so, in writing, by shareholders holding in the aggregate not
less than 10% of the outstanding shares having voting rights of the Trust. Such
request need specify the purpose for the meeting. 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 by shareholders holding in
the aggregate not less than 10% of the outstanding shares. If a shareholder
wishes to present a proposal to be included in the proxy statement for the next
meeting of shareholders of the Trust, such proposal must be received by the
Trust a reasonable time before the solicitation is to be made.

    THE TRUST WILL FURNISH, WITHOUT CHARGE, A COPY OF THE MOST RECENT ANNUAL AND
SEMI-ANNUAL REPORT TO SHAREHOLDERS TO CONTRACT OWNERS OF THE TRUST. COPIES OF

                  INVESTMENT ADVISORY AND MANAGEMENT AGREEMENT
 
    This INVESTMENT ADVISORY AND MANAGEMENT AGREEMENT is dated as of February

    In consideration of the mutual agreements herein made, the parties hereto
agree as follows:
 
    1.  DUTIES OF THE ADVISER.  The Adviser shall manage the affairs of the
Trust and the separate series of the Trust set forth in Schedule A attached
hereto (the "Portfolios"), including, 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, making purchase and sales of securities on behalf of
each Portfolio and determining how voting and other rights with respect to
securities owned by the Portfolios shall be exercised, subject in each case to
the control of the Trustees of the Trust (the "Trustees") and in accordance with
the objectives, policies and principles 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. In performing such
duties, the Adviser (i) shall provide such office space, such bookkeeping,

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) shall be responsible for
the financial and accounting records required to be maintained by each Portfolio
(including those maintained by the Fund's custodian) and (iii) shall oversee the
performance of services provided to each Portfolio by others, including the
custodian, transfer and shareholder servicing agent. The Trust understands that
the Adviser also acts as the manager of other investment companies.
 
    Subject to Section 36 of the Act, the Adviser shall not be liable to the
Portfolios or the Trust for any error of judgement or mistake of law or for any
loss arising out of any investment or for any act or omission in the management
of the Portfolios and the performance of its duties under this Agreement except
for willful misfeasance, bad faith or gross negligence in the performance of its
duties or by reason of reckless disregard of its obligations and duties under
this Agreement.
 
    2.  EXPENSES.  The Adviser shall pay all of its expenses arising from the
performance of its obligations under Section 1 and shall pay any salaries, fees
and expenses of the Trustees and Officers 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,

facilities and personnel provided by the Adviser pursuant to Section 1, the
Trust will pay to the Adviser, promptly after the end of each 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. However, the
amount of compensation payable to the Adviser may be restricted by applicable
state law limitations.
 
                                      A-1
<PAGE>
        (b) If the Adviser shall serve hereunder for less than the whole of any
    month, the fee hereunder shall be prorated.
 
    4.  PURCHASE AND SALE OF SECURITIES.  The Adviser shall purchase securities
from or through and sell securities to or through such persons, brokers or
dealer as the Adviser shall deem appropriate in order to carry out the policy
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. The
placing purchase and sale orders may be carried out by the Adviser or any
wholly-owned subsidiary of the Adviser.
 
    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.
 
    5.  TERM OF AGREEMENT.  This Agreement shall continue in full force and
effect until the earlier of (a) February 13 1992; 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 by the Act) of the Portfolio with respect to such
Portfolio, voting separately from any other Portfolio of the Trust, this
Agreement shall continue in full force and effect with respect to such Portfolio
from year to year thereafter if such continuance is approved in the manner
required by the Act and the Adviser shall not have notified such Portfolio in
writing at least 60 days prior to the anniversary date of the previous
continuance that it does not desire such continuance. This Agreement may be
terminated at any time, without payment of penalty by the Portfolios on 60 days
written notice to the Adviser, by vote of the Trustees, or by vote of a majority
of the outstanding voting securities (as defined by the Act).
 
    6.  MISCELLANEOUS.  This Agreement shall be governed by and construed in
accordance with the laws of the State of New York. Anything herein to the
contrary notwithstanding, this Agreement shall not be construed to require, or
to impose any duty upon either of the parties, to do anything in violation of
any applicable laws or regulations.
 
    The Declaration of Trust establishing the Trust of which each Portfolio is a
separate, designated series, 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.
 
    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.

                             SUB-ADVISORY AGREEMENT
 
    This Agreement dated February 13, 1990, as restated November 17, 1994, by
and between SunAmerica Asset Management Corp., a Delaware corporation (the
"Adviser"), 733 Third Avenue, New York, New York 10017, and Wellington
Management Company, a Massachusetts partnership ("Wellington"), 75 State Street,
Boston, Massachusetts 02109.
 
                              W I T N E S S E T H:
 
    WHEREAS, the parties hereto have entered into separate subadvisory
agreements, each dated February 13, 1990, with respect to each separate series
of Anchor Series Trust (the "Trust"); and
 
    WHEREAS, each such subadvisory agreement is identical with respect to their
terms and conditions; and
 
    WHEREAS, the parties have determined it desirable to consolidate all such
subadvisory agreements into one document for administrative convenience.
 
    NOW, THEREFORE, it is hereby agreed by and between the Adviser and
Wellington as follows:
 
    1.  DUTIES OF WELLINGTON.  Adviser hereby engages the services of Wellington
in furtherance of its Investment Advisory and Management Agreement with Anchor
Series Trust (the "Trust") dated February 13, 1990, on behalf of each separate
series of the Trust set forth in Schedule A attached hereto (the "Portfolios").
Pursuant to this Sub-Advisory Agreement and subject to the oversight and review
of Adviser, Wellington will manage the investment and reinvestment of the assets
of each Portfolio. Wellington will determine in its discretion, subject to the
oversight and review of 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 Adviser
and to officers and Trustees of the Trust concerning its discharge of the
foregoing responsibilities. Wellington 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 of each Portfolio set forth in the Trust's prospectus, and
applicable laws and regulations. Wellington accepts such employment and agrees,
at its own expense, to render the services and to provide the office space,
furnishings, equipment and personnel required by it to perform the services on
the terms and for the compensation provided in this Agreement.
 
    2.  PORTFOLIO TRANSACTIONS.  Wellington 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 available price and most
favorable execution, except as prescribed in this Agreement. Subject to policies
established by the Trustees of the Trust, Wellington may also be authorized to
effect individual securities transactions at commission rates in excess of the
minimum commission rates available, if Wellington determines in good faith that
such amount of commission is reasonable in relation to the value of the
brokerage or research services provided by such broker or dealer, viewed in
terms of either that particular transaction or Wellington's overall
responsibilities with respect to each Portfolio of the Trust and other clients
of Wellington. 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. Wellington 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 WELLINGTON.  As its compensation hereunder, the Adviser
shall pay to Wellington on the last day of each calendar month, or as promptly
as possible thereafter, a fee calculated in accordance with the average daily
net assets of the indicated Portfolio as set forth in Schedule A attached
hereto.
 
                                      C-1
<PAGE>
    4.  OTHER SERVICES.  At the request of the Trust and Adviser, Wellington 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 Wellington and billed to the Trust
or Adviser at Wellington's cost.
 
    5.  REPORTS.  The Trust, Adviser, and Wellington agree to furnish to each
other, if applicable, current prospectuses, proxy statements, reports to
shareholders, certified copies of their financial statements, and such other
information with regard to their affairs as each may reasonably request.
 
    6.  STATUS OF WELLINGTON.  The services of Wellington to Adviser and the
Trust are not to be deemed exclusive, and Wellington shall be free to render
similar services to others so long as its services to the Trust are not impaired
thereby. Wellington 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.  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 Wellington on
behalf of the Trust are the property of the Trust and will be surrendered
promptly to the Trust or Adviser on request.
 
    8.  REFERENCE TO WELLINGTON.  Neither the Trust nor Adviser or any affiliate
or agent thereof shall make reference to or use the name of Wellington or any of
its affiliates in any advertising or promotional materials without the prior
approval of Wellington, which approval shall not be unreasonably withheld.
 
    9.  LIABILITY OF WELLINGTON.  In the absence of willful misfeasance, bad
faith, gross negligence or reckless disregard of obligations or duties
("disabling conduct") hereunder on the part of Wellington (and its officers,
directors, agents, employees, controlling persons, shareholders and any other
person or entity affiliated with Wellington) Wellington 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
Investment Company Act of 1940 concerning loss resulting from a breach of
fiduciary duty with respect to the receipt of compensation for services. Except
for such disabling conduct, the Trust shall indemnify Wellington (and its
officers, directors, agents, employees, controlling persons, shareholders and
any other person or entity affiliated with Wellington) from any liability
arising from Wellington's conduct under this Agreement.
 
    Indemnification to Wellington or any of its personnel or affiliates shall be
made when (i) 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 (ii) in the absence of such a
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 Investment Company
Act of 1940 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,
sub-advisers 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 he is entitled to indemnification. Such
advance shall be subject to at least one of the following: (1) the person to be
indemnified shall provide a security for his undertaking, (2) the Trust shall be
insured against losses arising by reason of any lawful advances, or (3) 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.
 
    10.  PERMISSIBLE INTERESTS.  Trustees and agents of the Trust are or may be
interested in Wellington (or any successor thereof) as directors, partners,
officers, or shareholders, or otherwise; directors, partners,
 
                                      C-2
<PAGE>
officers, agents, and shareholders of Wellington are or may be interested in the
Trust as trustees, or otherwise; and Wellington (or any successor) is or may be
interested in the Trust in some manner.
 
    11.  DURATION AND TERMINATION.  This Agreement, unless sooner terminated as
provided herein, shall continue with respect to each Portfolio until February
13, 1992, and thereafter, for periods of one year so long as such continuance
thereafter is specifically approved at least annually (a) 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 (b) by the Trustees of the Trust or by
vote of a majority of the outstanding voting securities of each Portfolio voting
separately from any other Portfolio of the Trust, provided, however, that if the
shareholders fail to approve the Agreement as provided herein, Wellington 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 vote of a majority of the outstanding voting
securities of each Portfolio with respect to that Portfolio or by the Adviser on
not less than 30 days nor more than 60 days written notice to Wellington or by
Wellington at any time without the payment of any penalty, on 90 days written
notice to Adviser and the Trust. This Agreement will automatically and
immediately terminate in the event of its assignment. 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 each Portfolio
and the Adviser dated February 13, 1990, 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.
 
    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
this instrument is executed on behalf of the Trustees as Trustees, and is not
binding upon any of the Trustees, officers, or shareholders of the Trust
individually but binding only upon the assets and property of the Trust.
 
    IN WITNESS WHEREOF, the parties have executed this Agreement on this 17th
day of November, 1994.
