(1) The front-end sales charge on Class A shares decreases with the size of the
    purchase to 0% for purchases of $1,000,000 or more. See 'Purchase of
    Shares.'
(2) Purchases of Class A shares in excess of $1,000,000 will be subject to a
    CDSC on redemptions made within one year of purchase. The CDSC on Class B
    shares applies only if a redemption occurs within six years from their
    purchase date. The CDSC on Class C shares applies only on redemptions made
    within one year of purchase.
(3) A $15.00 fee may be imposed for wire redemptions.
(4) 0.25% of the 12b-1 fee comprises an Account Maintenance and Service Fee. A
    portion of the Account Maintenance and Service Fee is paid for continuous
    personal service to investors in the Portfolios, such as responding to
    shareholder inquiries, quoting net asset values, providing current marketing
    material and attending to other shareholder matters. Class B or Class C
    shareholders who own their shares for an extended period of time may pay
    more in Rule 12b-1 distribution fees than the economic equivalent of the
    maximum front-end sales charge permitted under the Conduct Rules of the
    National Association of Securities Dealers, Inc.
(5) SunAmerica has voluntarily agreed to waive fees or reimburse expenses, if
    necessary, to keep operating expenses at or below an annual rate set forth
    above under Total Operating Expenses. The information provided in the table

    waivers/expense reimbursements. For the fiscal year ended October 31, 1997,

(1) The front-end sales charge on Class A shares decreases with the size of the
    purchase to 0% for purchases of $1,000,000 or more. See 'Purchase of
    Shares.'
(2) Purchases of Class A shares in excess of $1,000,000 will be subject to a
    CDSC on redemptions made within one year of purchase. The CDSC on Class B
    shares applies only if a redemption occurs within six years from their
    purchase date. The CDSC on Class C shares applies only on redemptions made
    within one year of purchase.
(3) A $15.00 fee may be imposed for wire redemptions.
(4) 0.25% of the 12b-1 fee comprises an Account Maintenance and Service Fee. A
    portion of the Account Maintenance and Service Fee is paid for continuous
    personal service to investors in the Portfolios, such as responding to
    shareholder inquiries, quoting net asset values, providing current marketing
    material and attending to other shareholder matters. Class B or Class C
    shareholders who own their shares for an extended period of time may pay
    more in Rule 12b-1 distribution fees than the economic equivalent of the
    maximum front-end sales charge permitted under the Conduct Rules of the
    National Association of Securities Dealers, Inc.
(5) SunAmerica has voluntarily agreed to waive fees or reimburse expenses, if
    necessary, to keep operating expenses at or below an annual rate set forth
    above under Total Operating Expenses. The information provided in the table
    represents estimated amounts for the current fiscal year net of the current
    fee waivers/expense reimbursements. For the fiscal year ended October 31,
    1997, the Other Expenses and Total Operating Expenses (on a gross basis)
    were: Value Portfolio, Class A, 0.77% and 2.12%; Value Portfolio, Class B,
    0.80% and 2.80%; Value Portfolio, Class C, 1.08% and 3.08%; International
    Equity Portfolio, Class A, 1.02% and 2.47%; International Equity Portfolio,
    Class B, 1.07% and 3.17%; International Equity Portfolio, Class C, 1.47% and
    3.57%. For the period October 15, 1997 (commencement of operations) through
    October 31, 1997, the Other Expenses and Total Operating Expenses (on a
    gross basis) were: Large-Cap Value Portfolio, Class A, 1.01% and 2.36%;
    Large-Cap Value Portfolio, Class B, 1.59% and 3.59%; Large-Cap Value
    Portfolio, Class C, 3.65% and 5.65%; Small-Cap Value Portfolio, Class A,

  shares. Therefore, with respect to the 10-year expense information, years 8, 9
  and 10 reflect the expenses attributable to ownership of Class A shares.
 
The foregoing examples, including the 5% return and the expenses used, are
intended to assist investors in understanding the costs and expenses that a
shareholder in the Fund will bear directly or indirectly, and should not be
considered a representation of past or future performance or expenses. For more

Style-Based Investing
- --------------------------------------------------------------------------------
 
Each Portfolio of the Fund is intended to provide investors with access to
several different professional investment advisers, each seeking the same
investment objective and utilizing a similar investment style with respect to a
separate portion of the Portfolio's assets. Normally, the investment decisions
for each Portfolio will be made by at least three Advisers, which may include
SunAmerica. SunAmerica will select Advisers that it believes will provide each
Portfolio with the highest quality investment services, while obtaining, within
each Portfolio's overall investment objective, a distinct investment style.
 
SunAmerica will generally allocate investments in each Portfolio (and redemption
requests) equally among its three Advisers. The Fund expects that differences in
investment returns among the portions of a Portfolio managed by different
Advisers will cause the actual percentage of a Portfolio's assets managed by
each Adviser to vary over time. SunAmerica intends, on a quarterly basis, to
review the asset allocation in each Portfolio to ensure that no portion of
assets managed by an Adviser exceeds that portion managed by any other Adviser
to the Portfolio by more than 5%. If such a condition exists, SunAmerica will
then re-allocate cash flows among the three Advisers, differently from the
manner described above, in an effort to effect a re-balancing of the Portfolio's
asset allocation. SunAmerica does not intend, but reserves the right, to effect
such a re-balancing of asset allocation by re-allocating assets from one Adviser
to another. Re-balancing may involve re-directing cash flows from a better
performing Adviser to one with relatively lower returns.
 
From time to time, SunAmerica, with the approval of the Board, may add a new
Adviser for a Portfolio, replace an Adviser or reduce the number of Advisers for
a Portfolio. See 'Management of the Fund.'
 
Investment Objectives and Policies
- --------------------------------------------------------------------------------
 
The investment objective of each Portfolio is long-term growth of capital, and
each Portfolio seeks to achieve its investment objective primarily through
investment in equity securities. There can be no assurance that any Portfolio's
investment objective will be met or that the net return on an investment in a
Portfolio will exceed that which could have been obtained through other
investment or savings vehicles. The section 'Investment Techniques and Risk
Factors' contains a discussion of certain types of other securities in which
each Portfolio may invest and certain investment techniques that each Adviser
for the Portfolios may use. In addition, that section contains a discussion of
certain of the principal risks attendant to an investment in the Portfolios.
Although each Adviser for a Portfolio is permitted to invest in the various
types of securities and use the investment techniques indicated in that section,
no Adviser is required to invest in any particular type of permitted security or
to use any particular investment technique. Rather, each Adviser is given full
discretion to manage its portion of the assets of a Portfolio according to its
own investment philosophy.
 
Except as specifically indicated, each Portfolio's respective investment
objective and the investment policies and strategies described herein are not
fundamental policies of the Portfolio and may be changed by the Board without
the approval of shareholders. Certain investment restrictions may not be changed
without a majority vote of the outstanding voting securities of that Portfolio.
Each Portfolio's fundamental investment restrictions are described in the
Statement of Additional Information. For purposes of any investment policies or
restrictions discussed below, the percentage limitations of each Portfolio will
be applied by each Adviser to the portion of the Portfolio's assets managed by
that Adviser and will be determined at the time of an investment. SunAmerica,
however, is ultimately responsible for overseeing compliance by the Advisers,
and will in such capacity verify that in the aggregate the investments of each
Portfolio complies with applicable percentage limitations.
 
Each Portfolio is 'non-diversified' (as such term is defined under the 1940
Act), subject, however, to certain tax diversification requirements. See
'Dividends, Distributions and Taxes.'

The Growth Portfolios
- --------------------------------------------------------------------------------
 
The Growth Portfolios consist of the Large-Cap Growth Portfolio, Mid-Cap Growth
Portfolio and Aggressive Growth Portfolio. Under normal conditions, at least 65%
of each Growth Portfolio's total assets will be invested in equity securities
(including common and preferred stocks and other securities having equity
features, such as convertible securities, warrants and rights). The issuers of
such securities are companies considered by the respective Advisers to have a
historical record of above-average growth rate; to have significant growth
potential; above-average earnings growth or value or the ability to sustain
earnings growth; to offer proven or unusual products or services; or to operate
in industries experiencing increasing demand. The Advisers may select certain of
such securities because they consider them to be undervalued in the market. Each
of the Growth Portfolios may also invest in debt securities that the Advisers
expect have the potential for capital appreciation which are rated as low as
'BBB' by Standard & Poor's Corporation, a Division of the McGraw-Hill Companies
('S&P'), or 'Baa' by Moody's Investors Service, Inc. ('Moody's') or, if unrated,
determined by the Adviser to be of equivalent quality. The Large-Cap Growth
Portfolio and the Aggressive Growth Portfolio may also invest in debt securities
rated below 'BBB' or 'Baa' or unrated securities of comparable quality (junk
bonds). See 'Fixed Income Securities' in 'Investment Techniques and Risk
Factors' below for a discussion of the risks associated with investing in such
securities. The investment polices and strategies specific to each of the Growth
Portfolios are described below.
 
Large-Cap Growth Portfolio.  The Large-Cap Growth Portfolio, advised by Janus,
Papp and Montag & Caldwell, will invest, under normal circumstances, at least
65% of the Portfolio's total assets in the securities of companies that have, at
the time of purchase, a market capitalization in excess of $5 billion
('Large-Cap Companies').
 
Large-Cap Companies generally will be companies that have a substantial record
of operations (i.e., in business for at least five years) and are listed for
trading on the New York Stock Exchange ('NYSE'), American Stock Exchange
('AMEX') or on another national or international stock exchange or, in some
cases, are traded over-the-counter.
 
The Portfolio may also invest up to 35% of its total assets in securities of
issuers other than Large-Cap Companies. These investments may include equity
securities of companies with market capitalizations below $5 billion, including
companies with market capitalizations of less than $1 billion, and debt
securities that the Advisers expect have the potential for capital appreciation.
See 'Investment in Small-Cap Companies' and 'Fixed Income Securities' in
'Investment Techniques and Risk Factors' below for a discussion of the risks
associated with investing in such securities.
 

Mid-Cap Growth Portfolio.  The Mid-Cap Growth Portfolio, advised by MAS, T. Rowe
Price and Wellington Management, will invest, under normal circumstances, at
least 65% of the Portfolio's total assets in the securities of medium-sized
companies that have, at the time of purchase, a market capitalization between $1
billion and $5 billion ('Mid-Cap Companies').
 
Mid-Cap Companies generally will be companies that have a substantial record of
operations (i.e., in business for at least five years) and are listed for
trading on the NYSE or another national or international stock exchange or, in
some cases, are traded over-the-counter. Such companies, however, may be less
seasoned than Large-Cap Companies, as defined in 'Large-Cap Growth Portfolio,'
above. In general, the securities of Mid-Cap Companies may be more volatile than
those of Large-Cap Companies.
 
The Portfolio may also invest up to 35% of its total assets in securities of
issuers other than Mid-Cap Companies. These investments may include equity
securities of Large-Cap Companies and companies with market capitalizations of
less than $1 billion, and debt securities that the Advisers expect have the
potential for capital appreciation. See 'Investment in Small-Cap Companies' and
'Fixed Income Securities' in 'Investment Techniques and Risk Factors' below for
a discussion of the risks associated with investing in such securities.
 
Aggressive Growth Portfolio.  The Aggressive Growth Portfolio, advised by Janus,
SunAmerica and Warburg, will invest in equity securities to seek aggressively
and selectively long-term total return, without regard to the market
capitalization of an issuer. Generally, the Portfolio will invest in securities
of companies that have, at the time of purchase, a market capitalization of less
than $1 billion ('Small-Cap Companies') or Mid-Cap Companies, as defined in
'Mid-Cap Growth Portfolio,' above. The Advisers may also purchase securities of
Large-Cap Companies, as defined in 'Large-Cap Growth Portfolio,' above.

STYLE SELECT SERIES(Registered)

Small-Cap Companies generally will be companies that, although not 'start-up'
companies, have been in business for a shorter period of time than Mid-Cap or
Large-Cap Companies. Small-Cap Companies frequently will be in businesses or
industries involving new, recently developed products, services, or
technologies, or may be in businesses that are out of favor with or have not yet
been discovered by the broader investment community. While some Small-Cap
Companies may be listed for trading on a securities exchange, it is expected
that a significant portion of such companies will be traded over-the-counter.
 
There is no requirement that any minimum percentage of assets of the Portfolio
be maintained in securities of either Small-Cap Companies or Mid-Cap Companies.
In general, to the extent that more of the Portfolio's assets are invested in
Small-Cap Companies, the Portfolio's net asset value may be subject to more
volatility than if such assets were invested in larger companies. See
'Investment in Small-Cap Companies' in 'Investment Techniques and Risk Factors.'
In addition, the Portfolio may invest up to 35% of its total assets in debt
securities that the Advisers expect have the potential for capital appreciation.
See 'Fixed Income Securities' in 'Investment Techniques and Risk Factors' below
for a discussion of the risks associated with investing in such securities.
 
The Blend Portfolio
- --------------------------------------------------------------------------------
 
The Fund currently offers one Blend Portfolio, the Large-Cap Blend Portfolio,
the investment policies and strategies of which are described below.
 
Large-Cap Blend Portfolio.  The Large-Cap Blend Portfolio, advised by Lazard,
MSAM and T. Rowe Price, will invest, under normal circumstances, at least 65% of
the Portfolio's total assets in equity securities (including common and
preferred stocks and other securities having equity features, such as
convertible securities, warrants and rights) of Large-Cap Companies. Large-Cap
Companies have, at the time of purchase, a market capitalization in excess of $5
billion. Large-Cap Companies generally will be companies that have a substantial
record of operations (i.e., in business for at least five years) and are listed
for trading on the NYSE, AMEX or on another national or international stock
exchange or, in some cases, are traded over-the-counter. In selecting equity
securities of Large-Cap Companies, an Adviser will seek to achieve a blend of
what it considers to be growth companies, value companies and companies that the
Adviser believes have elements of both growth and value. An Adviser will
normally select securities of companies whose earnings are expected by the
Adviser to grow and to be able to support a growing dividend payment, as well as
securities that do not pay dividends currently but offer prospects of
appreciation and future income. Investments will be identified based upon
factors including undervalued assets or earnings potential, favorable operating
or price to cash flow ratios, a below-average price to book value ratio, a
below-average price to earnings ratio and, although current income will not
always be a significant factor in selecting securities, an above-average
dividend yield. Investments will also be identified based upon other factors
including above-average earnings growth and cash flow sufficient to support
growing dividends, as well as the prospect for capital appreciation and future
dividend payments with respect to securities that do not currently pay
dividends.
 
The Large-Cap Blend Portfolio may invest up to 35% of its total assets in
securities of issuers other than Large-Cap Companies. These investments may
include equity securities of companies with market capitalizations below $5
billion, including companies with market capitalizations of less than $1
billion. These investments may also include debt securities that the Advisers
expect to have the potential for capital appreciation, including debt securities
rated below 'BBB' by S&P, or 'Baa' by Moody's, or, if unrated, determined by the
Advisers to be of equivalent quality (junk bonds). See 'Investment in Small-Cap
Companies' and 'Fixed Income Securities' in 'Investment Techniques and Risk
Factors' below for a discussion of the risks associated with investing in such
securities.

The Value Portfolios
- --------------------------------------------------------------------------------
 
The Value Portfolios consist of the Large-Cap Value Portfolio, Value Portfolio
and Small-Cap Value Portfolio. Under normal circumstances, at least 65% of each
Value Portfolio's total assets will be invested in equity securities (including
common and preferred stocks and other securities having equity features, such as
convertible securities, warrants and rights). The Advisers will normally select
securities that they believe are selling at a price that is low relative to
their worth. Investments will be identified based upon factors including
undervalued assets or earnings potential, favorable operating or price to cash
flow ratios, a below-average price to book value ratio, a below-average price to
earnings ratio and, although current income will not always be a significant
factor in selecting securities, an above-average dividend yield. In addition,
the Advisers may take into account such other factors as an issuer's product
demand and development, resources for expansion, quality of management, overall
favorable business prospects and industry fundamentals. While the Advisers seek
to identify investments with the potential for above-average appreciation, there
is a risk that other investors will not recognize the intrinsic worth of a
security owned by the Value Portfolios for a long period, if at all. In
addition, there is the risk that a security judged to be undervalued by the
Advisers is actually appropriately priced due to fundamental problems with the
issuer's business prospects that are not yet apparent. Each of the Value
Portfolios may invest in debt securities that the Advisers expect to have the
potential for capital appreciation, which are rated as low as 'BBB' by S&P, or
'Baa' by Moody's, or, if unrated, determined by the Advisers to be of equivalent
quality. The Value Portfolio and Small-Cap Value Portfolio may also invest in
debt securities rated below 'BBB' or 'Baa' or unrated securities of comparable
quality (junk bonds). See 'Fixed Income Securities' in 'Investment Techniques
and Risk Factors' below for a discussion of the risks associated with investing
in such securities. The investment policies and strategies specific to each of
the Value Portfolios are described below.
 
Large-Cap Value Portfolio.  The Large-Cap Value Portfolio, advised by Babson,
Davis and Wellington Management, will invest, under normal circumstances, at
least 65% of the Portfolio's assets in securities of Large-Cap Companies that
the Advisers believe are selling at a price that is low relative to their worth.
Large-Cap Companies have, at the time of purchase, a market capitalization in
excess of $5 billion. Large-Cap Companies generally will be companies that have
a substantial record of operations (i.e., in business for at least five years)
and are listed for trading on the NYSE, AMEX or on another national or
international stock exchange or, in some cases, are traded over-the-counter.
 
The Portfolio may also invest up to 35% of its total assets in securities of
issuers other than Large-Cap Companies. These investments may include equity
companies with market capitalizations below $5 billion, including companies with
market capitalizations of less than $1 billion, and debt securities that the
Advisers expect to have the potential for capital appreciation. See 'Investment
in Small-Cap Companies' and 'Fixed Income Securities' in 'Investment Techniques
and Risk Factors' below for a discussion of the risks associated with investing
in such securities.
 
Value Portfolio.  The Value Portfolio, advised by Davis, Neuberger&Berman, and
Strong/Schafer, will invest, under normal circumstances, in securities that the
Advisers believe are selling at a price that is low relative to their worth,
without regard to the market capitalization of the issuer. It is anticipated
that a significant portion of the Portfolio's assets as a whole will generally
be invested in securities of Mid-Cap Companies, which have, at the time of
purchase, a market capitalization between $1 billion and $5 billion; however,
any particular Adviser may not necessarily invest a significant portion of the
Portfolio's assets allocated to it in such companies. Mid-Cap Companies
generally will be companies that have a substantial record of operations (i.e.,
in business for at least five years) and are listed for trading on the NYSE,
AMEX or on another national or international stock exchange or, in some cases,
are traded over-the-counter. Investing in such companies may have greater risks
than investing in larger companies.
 
The Portfolio may also invest up to 35% of its total assets in debt securities
that the Advisers expect to have the potential for capital appreciation. See
'Fixed Income Securities' in 'Investment Techniques and Risk Factors.'
 
Small-Cap Value Portfolio.  The Small-Cap Value Portfolio, advised by
Berger/PWM, Lazard and Glenmede, will invest, under normal circumstances, at
least 65% of the Portfolio's total assets in securities of Small-Cap Companies
that the Advisers believe are selling at a price that is low relative to their
worth. Small-Cap Companies have, at the time

<PAGE>

STYLE SELECT SERIES(Registered)

of purchase, a market capitalization of less than $1 billion. Small-Cap
Companies generally will be companies that, although not 'start-up' companies,
have been in business for a shorter period of time than Mid-Cap or Large-Cap
Companies. Small-Cap Companies frequently will be in businesses or industries
involving new, recently developed products, services, or technologies, or may be
in businesses that are out of favor with or have not yet been discovered by the
broader investment community. While some Small-Cap Companies may be listed for
trading on a securities exchange, it is expected that a significant portion of
such companies will be traded over-the-counter. In general, to the extent that
the Portfolio's assets are invested in Small-Cap Companies, the Portfolio's net
asset value may be subject to more volatility than if such assets were invested
in larger companies. See 'Investment in Small-Cap Companies' in 'Investment
Techniques and Risk Factors.'
 
The Portfolio may also invest up to 35% of its total assets in equity securities
of issuers other than Small-Cap Companies and in debt securities that the
Advisers expect have the potential for capital appreciation. See 'Fixed Income
Securities' in 'Investment Techniques and Risk Factors' below for a discussion
of the risks associated with investing in such securities.
 
The International Portfolio
- --------------------------------------------------------------------------------
 
The Fund currently offers one International Portfolio, the International Equity
Portfolio, the investment policies and strategies of which are described below.
 
International Equity Portfolio.  The International Equity Portfolio, advised by
BT, Rowe-Fleming and Warburg will invest, under normal circumstances, in
securities of non-U.S. issuers. Country selection is a significant part of each
Adviser's investment process. The Portfolio is permitted to invest in any
country where it is legal for U.S. investors to invest.
 
The Portfolio will invest in securities of companies without regard to their
market capitalization. However, investing in smaller companies may have greater
risks than investing in larger companies. See 'Investment in Small-Cap
Companies' in 'Investment Techniques and Risk Factors.' The Portfolio may also
invest from time to time in companies located in countries considered to be
emerging markets (i.e., those generally considered to be in emerging or
developing countries). Investment in foreign securities in general, and in
emerging markets in particular, involves certain risks not present when
investing in United States securities. See 'Foreign Securities' in 'Investment
Techniques and Risk Factors.'
 
Under normal conditions, at least 65% of the Portfolio's total assets will be
invested in equity securities (including common and preferred stocks and other
securities having equity features, such as convertible securities, warrants and
rights) of issuers in at least three countries other than the United States. The
Portfolio may purchase securities on foreign stock exchanges, on U.S. stock
exchanges, or in the over-the-counter market. In addition, the Portfolio may
invest in securities in the form of sponsored or unsponsored American Depositary
Receipts ('ADRs'), European Depositary Receipts ('EDRs'), Global Depositary
Receipts ('GDRs') or other similar securities representing a right to obtain
underlying securities of foreign issuers. The Portfolio may invest up to 35% of
its total assets in debt securities that the Advisers expect have the potential
for capital appreciation. The Portfolio may invest in such debt securities rated
below investment grade, that is below 'BBB' by S&P, or below 'Baa' by Moody's,
or, if unrated, determined by the Advisers to be of equivalent quality (junk
bonds). See 'Fixed Income Securities' in 'Investment Techniques and Risk
Factors' below for a discussion of the risks associated with investing in such
securities.

Advisers' Historical Performance Data
- --------------------------------------------------------------------------------
 
Set forth below is historical performance data relating to each of the Advisers
selected by SunAmerica for the Portfolios. The performance information presented
below is based on data provided by each Adviser relating to accounts managed by
that Adviser that have investment objectives and policies similar (although not
necessarily identical) to the relevant Portfolio and are advised by that Adviser
using investment styles and strategies substantially similar to those to be
employed by that Adviser in advising its portion of the Portfolio. THE
PERFORMANCE INFORMATION SET FORTH BELOW FOR THE RESPECTIVE ADVISERS DOES NOT
REPRESENT THE PERFORMANCE OF THE FUND OR ANY PORTFOLIO. The Large-Cap Growth,
Large-Cap Blend, Large-Cap Value and Small-Cap Value Portfolios are recently
organized and have performance records of less than a year. The following
performance should not be considered a prediction of future performance of the
Fund or any Portfolio. The performance of a particular Portfolio may be higher
or lower than that of the respective Advisers shown below.
 
All of the Advisers' historical performance information reflects annualized
total return over the stated period of time. Total return shows how much an
investment has increased (decreased) over a specified period of time and
includes capital appreciation and income. The term 'annualized total return'
signifies that cumulative total returns for a stated time period (i.e., 1, 3, 5
or 10 years) have been annualized over such period. In order to present the
total return information in a consistent manner, all returns were calculated by
geometrically linking quarterly total return data for the relevant number of
quarters and annualizing the result over the equivalent number of years.
 
All information is based on data supplied by the Advisers or Morningstar, Inc.
('Morningstar') and believed by the Fund to be reliable. Where an Adviser's
performance is based on a single account, performance has been calculated in
accordance with prescribed Securities and Exchange Commission guidelines. Where
composite performance information is provided, the total return for each
Adviser's composite performance has been calculated in accordance with
Performance Presentation Standards of the Association for Investment Management
and Research ('AIMR'). Unless otherwise indicated, the performance, while having
been calculated in accordance with either Securities and Exchange Commission or
AIMR methodology, has not been independently verified or audited. AIMR's method
of calculating performance differs from that of the Securities and Exchange
Commission. Performance figures for any particular Adviser do not necessarily
reflect all of the Adviser's assets under management and may not accurately
reflect the performance of all accounts managed by the Adviser.
 
Where the performance information of an Adviser in the following tables
constitutes a single account, it is presented net of actual fees charged by the
individual Advisers, except as otherwise noted, and reflects the imposition of
any sales loads or charges to such account, if applicable. Where an Adviser
provides composite performance, one of two types of composites may be used, a
'net composite' or a 'gross composite.' In a net composite, the performance
return of each account in the composite is reduced by the actual fees charged to
that particular account. In a gross composite, the gross composite performance
return is reduced by the highest annual expenses charged to any account included
in the particular composite.
 
Certain of the client accounts that are included in an Adviser's past
performance record may not be registered investment companies. Such accounts
would not be subject to the same types of expenses to which the Fund is subject,
nor to the specific diversification and other restrictions and investment
limitations imposed on the Fund and its Portfolios by the 1940 Act or Subchapter
M of the Internal Revenue Code of 1986, as amended (the 'Code'). The performance
results that include accounts that are not registered investment companies might
have been less favorable had they been subject to regulation as investment
companies under the relevant federal laws.
 
Finally, for each period presented, the investment performance for the Advisers
of each Portfolio is compared to the average performance of a group of similar
mutual funds tracked by Morningstar. Morningstar calculates its group averages
by taking a mathematical average of the returns of the funds included in the
group.

INDIVIDUAL ADVISER PERFORMANCE
 
Except as otherwise noted below, an Adviser's performance is presented net of
actual fees and reflects the imposition of any sales loads or charges, if
applicable. The Portfolio's fees and expenses may be greater than those charged
by the individual Advisers. Accordingly, the Portfolio's actual performance
results may be less.
 
  Janus
 

Janus' historical performance data covers 10 years and reflects the performance
of the Janus Earnings Growth Composite (which includes mutual funds). The
composite includes all accounts, including the Portfolio, over $5 million with
investment objectives, policies and strategies substantially similar to those to
be used by Janus in managing its portion of the Large-Cap Growth Portfolio. 15
such accounts, with net assets totaling $27 million (less than 1% of the total
assets in the 62 similar accounts), have been omitted from the composite. Such
omission, however, does not render the performance information presented
misleading. As of March 31, 1998, the composite included 47 accounts with
aggregate assets of $16.1 billion. The composite returns are presented net of
actual fees. None of the accounts included in the composite bears any sales
loads or charges.
 
  Papp
 

Papp's historical performance data covers 6 1/4 years (the period since
inception) and reflects the performance of a single account, which is a no-load
mutual fund. The annualized return since inception of the account is 20.2% as of
March 31, 1998. Papp manages 2 accounts, including the Portfolio, with
investment objectives, policies and strategies substantially similar to those to
be used by Papp in managing its portion of the Large-Cap Growth Portfolio. The
omission of the Portfolio, with assets of approximately $10.1 million (less than
3% of the total assets in the 2 accounts), does not render the performance
information misleading. As of March 31, 1998, the account's net assets totaled
$361.5 million. The returns are presented net of actual fees.
 
  Montag & Caldwell
 

Montag & Caldwell's historical performance data covers 10 years and reflects the
performance of the Montag & Caldwell Growth Composite. The composite includes
all accounts, including the Portfolio, with investment objectives, policies and
strategies substantially similar to those used by Montag & Caldwell in managing
its portion of the Large-Cap Growth Portfolio, except that 15 such accounts,
with net assets totaling $32 million (less than 1% of the total assets in the
168 similar accounts), have been omitted from the composite. Such omission,
however, does not render the performance information presented misleading. As of
March 31, 1998, the composite included 153 accounts with aggregate assets of
$7.8 billion. The composite returns are presented net of actual fees. None of
the accounts included in the composite bears any sales load or charges.
 
  Morningstar Large Growth Category
 
Developed by Morningstar, the Morningstar Large Growth Category currently
reflects a group of 289 mutual funds which have portfolios with median market
capitalizations, price/earnings ratios, and price/book ratios similar to those
of the Large-Cap Growth Portfolio.

INDIVIDUAL ADVISER PERFORMANCE
 
Except as otherwise noted below, an Adviser's performance is presented net of
actual fees and reflects the imposition of any sales load or charges, if
applicable. The Portfolio's fees and expenses may be greater than those charged
by the individual Advisers. Accordingly, the Portfolio's actual performance
results may be less.
 
  MAS
 
MAS' historical performance data covers 8 years (the period since inception) and
reflects the performance of a single account, which is a no-load mutual fund.
The annualized return since inception of the account is 23.0% as of March 31,
1998. MAS manages 2 accounts, including the Portfolio, with investment
objectives, and investment policies and strategies substantially similar to
those to be used by MAS in managing its portion of the Mid-Cap Growth Portfolio.
The omission of the Portfolio, with assets of approximately $32 million (5.5% of
the total assets in the 2 accounts), does not render the performance information
misleading. As of March 31, 1998, the account's net assets totaled $550.8
million. The returns are presented net of actual fees.
 
  T. Rowe Price
 
T. Rowe Price's historical performance data covers 6 years (the period since
inception) and reflects the performance of a single account, which is a no-load
mutual fund. The annualized return since inception of the account is 26.2% as of
March 31, 1998. T. Rowe Price manages a total of 9 accounts (5 of which are
institutional accounts and 4 of which are mutual funds) with investment
objectives, policies and strategies substantially similar to those used in
managing its portion of the Mid-Cap Growth Portfolio. T. Rowe Price does not
calculate composite performance for mutual fund accounts nor does it calculate a
combined composite of the institutional accounts' performance and the mutual
funds' performance. Three of the accounts do not have performance records as of
March 31, 1998. The omission of the other 5 accounts, with assets of
approximately $653.7 million (less than 22% of the total assets in the 9
accounts), does not render the performance information presented misleading. As
of March 31, 1998, the account's net assets totaled approximately $2.3 billion.
The returns are presented net of actual fees.
 
  Wellington Management
 
Wellington Management's historical performance data covers 6 3/4 years and
reflects the performance of the Wellington Management Mid-Cap Growth Composite.
The annualized return since inception of the Composite is 21.3%. The Composite
includes all accounts with investment objectives, policies and strategies
substantially similar to those used by Wellington Management in managing its
portion of the Mid-Cap Growth Portfolio. As of March 31, 1998 the Composite
included 20 separately managed accounts totaling $1.2 billion of assets under
management. The returns for the Composite were supplied to the Portfolio by
Wellington Management, and are presented net of management--related fees for the

NOTES (AGGRESSIVE GROWTH PORTFOLIO)
- --------------------------------------------------------------------------------
 
INDIVIDUAL ADVISER PERFORMANCE
 
Except as otherwise noted below, an Adviser's performance is presented net of
actual fees and reflects the imposition of any sales loads or charges, if
applicable. The Portfolio's fees and expenses may be greater than those charged
by the individual Advisers. Accordingly, the Portfolio's actual performance
results may be less.
 
  Janus
 
Janus' historical performance data covers 8 1/4 years (the period since
inception) and reflects the performance of the Janus Aggressive Growth Composite
(which includes mutual funds). The annualized return since inception of the
composite is 25.8% as of March 31, 1998. The composite includes all accounts,
including the Portfolio, over $5 million with investment objectives, policies
and strategies substantially similar to those used by Janus in managing its
portion of the Aggressive Growth Portfolio. 16 such accounts, with net assets
totaling $50 million (less than 5% of the total assets in the 30 similar
accounts), have been omitted from the composite. Such omission, however, does
not render the performance information presented misleading. As of March 31,
1998, the composite included 14 accounts with aggregate assets of $1.0 billion.
The composite returns are presented net of actual fees. None of the accounts
included in the composite bears any sales loads or charges.
 
  SunAmerica
 
SunAmerica's historical performance data covers 10 years and reflects the
performance of a single account, which is a front-end load mutual fund. The
annualized ten-year return of the account is 15.0% as of March 31, 1998.
SunAmerica manages a total of 3 accounts, including the Portfolio, (all of which
are mutual funds) with investment objectives, policies and strategies
substantially similar to those used in managing its portion of the Aggressive
Growth Portfolio. SunAmerica does not calculate composite performance for mutual
fund accounts. The omission of 2 of the accounts, with assets totaling $156.0
million (less than 38% of the total assets in the 3 accounts), does not render
the performance information presented misleading. As of March 31, 1998, the
account's net assets totaled $259.0 million. The returns presented in the chart
are net of actual fees and reflect the imposition of a front-end sales charge.
 
  Warburg
 
Warburg's historical performance data covers approximately 7 years and reflects
the performance of a single account, which is a no-load mutual fund. The
annualized return since inception of the account is 19.11% as of March 31, 1998.
Warburg manages a total of 3 accounts, including the Portfolio, (1 of which is
an institutional account and 2 of which are mutual funds) with investment
objectives, policies and strategies substantially similar to those to be used in
managing its portion of the Aggressive Growth Portfolio. Warburg does not
calculate a combined composite performance for its mutual fund accounts, nor
does it calculate a combined composite of the institutional account's
performance and the mutual funds' performance. However, the performance for the
other 2 accounts was, in the aggregate, better than that shown for the account
and, therefore, the omission of such accounts does not render the performance
information presented misleading. As of March 31, 1998, the account's net assets
totaled $432.1 million, which represented approximately 17.8% of the total
assets in the 3 similar accounts. The returns are presented net of actual fees.
 
  Morningstar Aggressive Growth Objective
 
Developed by Morningstar, the Morningstar Aggressive Growth Objective currently
reflects a group of 141 mutual funds which seek rapid growth of capital. The
group typically employ strategies that involve greater risk than those used by
most equity funds.

- --------------------------------------------------------------------------------
 
INDIVIDUAL ADVISER PERFORMANCE
 
Except as otherwise noted below, an Adviser's performance is presented net of
actual fees, and reflects the imposition of any sales loads or charges, if
applicable. The Portfolio's fees and expenses may be greater than those charged
by the individual Advisers. Accordingly, the Portfolio's actual performance
results may be less.
 
  Lazard
 
Lazard's historical performance data covers 10 years and reflects the
performance of Lazard's U.S. Equity Composite. The composite includes all
accounts, including the Portfolio, with investment objectives, policies and
strategies substantially similar to those to be used by Lazard in managing its
portion of the Large-Cap Blend Portfolio, except that 41 such accounts, with net
assets totaling $2.9 million (less than 1% of the total assets in the 96 similar
accounts), have been omitted from the composite. Such omission, however, does
not render the performance information presented misleading. As of March 31,
1998, the composite included 55 accounts totaling over $6.6 billion in assets
under management. The returns are presented net of actual fees. None of the
accounts included in the composite bears any sales loads or charges.

 
  MSAM
 
MSAM's historical performance data covers 6 3/4 years (the period since
inception) and reflects the performance of a single account, which is a no-load
mutual fund. The annualized return since inception of the account is 21.0% as of
March 31, 1998. MSAM manages a total of 16 accounts (12 of which are
institutional accounts and 4 of which are mutual funds) with investment
objectives, policies and strategies substantially similar to those to be used in
managing its portion of the Large-Cap Blend Portfolio. MSAM does not calculate
composite performance for its mutual fund accounts nor does it calculate a
combined composite of the institutional accounts' performance and the mutual
funds' performance. However, the performance for the other 15 accounts was, in
the aggregate, better than that shown for the fund and, therefore, the omission
of such accounts does not render the performance information presented
misleading. As of March 31, 1998, the fund's net assets totaled $759.0 million,
which represented approximately 38.2% of the total assets in the 16 similar
accounts. The returns presented in the chart are net of actual fees.
 
  T. Rowe Price
 
T. Rowe Price's historical performance data covers 10 years and reflects the
performance of a single account, which is a no-load mutual fund. T. Rowe Price
manages 2 accounts, including the Portfolio, with investment objectives,
policies and strategies substantially similar to those to be used by T. Rowe
Price in managing its portion of the Large-Cap Blend Portfolio. The omission of
the Portfolio, with assets of approximately $30.8 million (approximately 1% of
the total assets in the 2 accounts), does not render the performance information
misleading. As of March 31, 1998, the account's net assets totaled over $3.7
billion. The returns are presented net of actual fees.
 
  Morningstar Large Blend Category

INDIVIDUAL ADVISER PERFORMANCE
 
Except as otherwise noted below, an Adviser's performance is presented net of
actual fees and reflects the imposition of any sales loads or charges, if
applicable. The Portfolio's fees and expenses may be greater than those charged
by the individual Advisers. Accordingly, the Portfolio's actual performance
results may be less.
 
  Babson
 
Babson's historical performance data covers 10 years and reflects the
performance of the Babson Value Composite. According to Babson, the composite
includes all accounts, including the Portfolio, with investment objectives,
policies and strategies substantially similar to those used by Babson in
managing its portion of the Large-Cap Value Portfolio. Composite returns with
respect to the period prior to 1995 are based on results from a single account,
which is a no-load mutual fund, and, with respect to the period from 1995 to
present, are based on results from fully discretionary separate accounts and
no-load mutual funds advised by Babson. As of March 31, 1998, the composite
included 53 accounts with aggregate assets of $2.0 billion. The composite
returns are presented net of actual fees. None of the accounts included in
composite bears any sales loads or charges.

 
  Davis
 
Davis' historical performance data covers 10 years and reflects the performance
of a single account, which is a front-end load mutual fund. Davis manages a
total of 14 accounts, including the Portfolio, (9 of which are institutional
accounts and 5 of which are mutual funds) with investment objectives, policies
and strategies substantially similar to those used in managing its portion of
the Large-Cap Value Portfolio. Davis does not calculate composite performance
for either its institutional accounts or its mutual fund accounts, nor does it
calculate a combined composite of the institutional accounts' performance and
the mutual funds' performance. However, the performance for the other 13
accounts was, in the aggregate, better than that shown for the account and,
therefore, the omission of such accounts does not render the performance
information presented misleading. As of March 31, 1998, the account's net assets
totaled $10.4 billion, which represented approximately 82% of the total assets
in the 14 similar accounts. The returns presented in the chart are net of actual
fees and reflect the imposition of a front-end sales charge.

 
  Wellington Management
 
Wellington Management's historical performance data covers 10 years and reflects
the performance of the Wellington Management Value/Yield Composite. The
composite includes all accounts, including the Portfolio, with investment
objectives, policies and strategies substantially similar to those used by
Wellington Management in managing its portion of the Large-Cap Value Portfolio.
As of March 31, 1998, the composite included 12 discretionary separate accounts
and mutual funds totaling $3.4 billion of assets under management. The returns
for the composite were supplied by Wellington Management and are presented net
of management-related fees for the periods during which each account is included
in the Composite.
 
  Morningstar Large Value Category
 
Developed by Morningstar, the Morningstar Large Value Category reflects a group

NOTES (VALUE PORTFOLIO)

INDIVIDUAL ADVISER PERFORMANCE
 
Except as otherwise noted below, an Adviser's performance is presented net of
actual fees and reflects the imposition of any sales loads or charges, if
applicable. The Portfolio's fees and expenses may be greater than those charged
by the individual Advisers. Accordingly, the Portfolio's actual performance
results may be less.
 
  Davis
 
Davis' historical performance data covers 10 years and reflects the performance
of a single account, which is a front-end load mutual fund. Davis manages a
total of 14 accounts, including the Portfolio, (9 of which are institutional
accounts and 5 of which are mutual funds) with investment objectives, policies
and strategies substantially similar to those used in managing its portion of
the Value Portfolio. Davis does not calculate composite performance for either
its institutional accounts or its mutual fund accounts, nor does it calculate a
combined composite of the institutional accounts' performance and the mutual
funds' performance. However, the performance for the other 13 accounts was, in
the aggregate, better than that shown for the account and, therefore, the
omission of such accounts does not render the performance information presented
misleading. As of March 31, 1998, the account's net assets totaled $10.4
billion, which represented approximately 82% of the total assets in the 14
similar accounts. The returns presented in the chart are net of actual fees and
reflect the imposition of a front-end sales charge.

 
  Neuberger&Berman
 
Neuberger&Berman's historical performance data covers 10 years and reflects the
performance of a single account, which is a no-load mutual fund.
Neuberger&Berman manages 2 accounts, including the Portfolio, with investment
objectives, policies and strategies substantially similar to those to be used by
Neuberger&Berman in managing its portion of the Value Portfolio. The omission of
the Portfolio, with assets of approximately $72.0 million (less than 2% of the
total assets in the 2 accounts), does not render the performance information
misleading. As of March 31, 1998, the account's net assets totaled $4.62
billion. The returns are presented net of actual fees.
 
  Strong/Schafer
 
Strong/Schafer's historical performance data covers 10 years and reflects the
performance of the Schafer Capital Equity Composite. The composite includes all
accounts, including the Portfolio, with investment objectives, policies and
strategies substantially similar to those used by Strong/Schafer in managing its
portion of the Value Portfolio. As of March 31, 1998, the composite included 3
separately managed accounts and 2 mutual funds totaling approximately $2.2
billion of assets under management. The returns are presented net of actual
fees. None of the accounts in the composite bears any sales loads or charges.
Prior to January 1, 1993, not all composite calculations complied with AIMR.
Accordingly, performance results prior to January 1, 1993 do not comply with
AIMR.
 
  Morningstar Mid-Cap Value Category
 
Developed by Morningstar, the Morningstar Mid-Cap Value Category currently
reflects a group of 203 mutual funds which have portfolios with median market
capitalizations, price/earnings ratios, and price/book ratios similar to those
expected for the Value Portfolio.

NOTES (SMALL-CAP VALUE PORTFOLIO)
- --------------------------------------------------------------------------------
 
INDIVIDUAL ADVISER PERFORMANCE
 
Except as otherwise noted below, an Adviser's performance is presented net of
actual fees and reflects the imposition of any sales loads or charges, if
applicable. The Portfolio's fees and expenses may be greater than those charged
by the individual Advisers. Accordingly, the Portfolio's actual performance
results may be less.
 
  Berger/PWM
 
Berger/PWM's historical performance data covers 10 years and reflects the
performance of a single account, which is a no-load mutual fund. Berger/ PWM
manages 2 accounts, including the Portfolio, with investment objectives,
policies and strategies substantially similar to those used by Berger/PWM in
managing its portion of the Small-Cap Value Portfolio. The omission of the
Portfolio, with assets of approximately $13.4 million (approximately 7% of the
total assets in the 2 accounts), does not render the performance information
misleading. As of March 31, 1998, the account's net assets totaled $178.2
million. The returns are presented net of actual fees.

 
  Lazard
 
Lazard's historical performance data covers 10 years and reflects the
performance of the Lazard U.S. Small Cap Equity Composite. The composite
includes all accounts with investment objectives, policies and strategies
substantially similar to those to be used by Lazard in managing its portion of
the Small-Cap Value Portfolio, except that 24 such accounts, with net assets
totaling $721.3 million (less than 30.5% of the total assets in the 49
accounts), have been omitted from the composite. Such omission, however, does
not render the performance information presented misleading. As of March 31,
1998, the composite included 25 accounts totaling $1.6 billion in assets under
management. The returns for the composite were supplied to the Fund by Lazard
gross of certain fees, but have been adjusted to reflect the highest fees
charged to any account included in the composite for the reporting period. None
of the accounts included in the composite bears any sales loads or charges.

 
  Glenmede
 
Glenmede's historical performance data covers approximately 7 years (the period
since inception) and reflects the performance of a single account, which is a
no-load mutual fund. The annualized return since inception of the account is
18.4% as of March 31, 1998. Glenmede manages 2 accounts, including the
Portfolio, with investment objectives, policies and strategies substantially
similar to those used in managing its portion of the Small-Cap Value Portfolio.
The omission of the Portfolio, with assets of approximately $12.7 million (less
than 3% of the total assets in the 2 accounts), does not render the performance
information misleading. As of March 31, 1998, the account's net assets totaled
$488 million. The returns for the account were supplied to the Fund by Glenmede
gross of certain fees, but have been adjusted to reflect the highest fees
charged to the account for the reporting period.

Developed by Morningstar, the Morningstar Small Value Category currently

INDIVIDUAL ADVISER PERFORMANCE
 
Except as otherwise noted below, an Adviser's performance is presented net of
actual fees. The Portfolio's fees and expenses may be greater than those charged
by the individual Advisers. Accordingly, the Portfolio's actual performance
results may be less.
 
  BT
 
BT's historical performance data covers 10 years and reflects the performance of
the BT International Equity Composite, which consists of 2 accounts, one of
which is a mutual fund and the other an institutional account. These accounts
represent all of those managed by BT with an investment objective, policies and
strategy substantially similar to those to be used in managing its portion of
the International Equity Portfolio. As of March 31, 1998, the net assets managed
under the 2 accounts totaled approximately $2.0 billion. The returns are
presented net of actual fees and sales charges.

 
  Rowe-Fleming
 
Rowe-Fleming's historical performance data covers 10 years and reflects the
performance of a single account, which is a no-load mutual fund. Rowe-Fleming
manages a total of 36 accounts (13 of which are institutional accounts and 23 of
which are mutual funds) with investment objectives, policies and strategies
substantially similar to those to be used in managing its portfolio of the
International Equity Portfolio. Although Rowe-Fleming calculates composite
performance for its institutional accounts, it does not calculate composite
performance for mutual fund accounts, nor does it calculate a composite which
combines the institutional accounts' composite performance with the mutual
funds' performance. However, the performance for the other 35 accounts was, in
the aggregate, better than that shown for the account and, therefore, the
omission of such accounts does not render the performance information presented
misleading. As of March 31, 1998, the account's net assets totaled approximately
$10.6 billion, which represented approximately 49.5% of the total assets in the
36 similar accounts. The returns are presented net of actual fees.

 
  Warburg
 
Warburg's historical performance data covers approximately 7 years and reflects
the performance of a single account, which is a no-load mutual fund. The
annualized return since inception of the account is 10.0% as of March 31, 1998.
Warburg manages a total of 9 accounts (1 of which is an institutional account
and 8 of which are mutual funds) with an investment objective, policies and
strategy substantially similar to those to be used in managing its portion of
the International Equity Portfolio. Warburg does not calculate a combined
composite performance for its mutual fund accounts, nor does it calculate a
combined composite of the institutional account's performance and the mutual
funds' performance. However, the performance for the other 8 accounts was, in
the aggregate, better than that shown for the account and, therefore, the
omission of such accounts does not render the performance information presented
misleading. As of March 31, 1998, the account's net assets totaled $406.5
million, which represented approximately 8.1% of the total assets in the 9
similar accounts. The returns are presented net of actual fees.

INVESTMENT TECHNIQUES AND RISK FACTORS
- --------------------------------------------------------------------------------
 
Unless otherwise specified, each Portfolio may invest in the following
securities. As used herein, the term 'Adviser' shall mean either SunAmerica or
one of the Advisers chosen by SunAmerica. Also, the stated percentage
limitations are applied to an investment at the time of purchase unless
otherwise indicated.
 
Convertible Securities, Preferred Stocks, Warrants and Rights--Convertible
securities may be debt securities or preferred stock with a conversion feature.
Traditionally, convertible securities have paid dividends or interest at rates
higher than common stocks but lower than non-convertible securities. They
generally participate in the appreciation or depreciation of the underlying
stock into which they are convertible, but to a lesser degree. In recent years,
convertibles have been developed which combine higher or lower current income
with options and other features. Generally, preferred stock has a specified
dividend and ranks after bonds and before common stocks in its claim on income
for dividend payments and on assets should the company be liquidated. While most
preferred stocks pay a dividend, a Portfolio may purchase preferred stock where
the issuer has omitted, or is in danger of omitting, payment of its dividend.
Such investments would be made primarily for their capital appreciation
potential.
 
Warrants are options to buy a stated number of shares of common stock at a
specified price any time during the life of the warrants (generally two or more
years). Rights represent a preemptive right of stockholders to purchase
additional shares of a stock at the time of a new issuance before the stock is
offered to the general public, allowing the stockholder to retain the same
ownership percentage after the new stock offering.
 
Investment in Small-Cap Companies--Each Portfolio may invest in small companies
having market capitalizations of under $1 billion. It may be difficult to obtain
reliable information and financial data on such companies and the securities of
these small companies may not be readily marketable, making it difficult to
dispose of shares when desirable. Securities of small or emerging growth
companies may be subject to more abrupt or erratic market movements and less
market liquidity than larger, more established companies or the market average
in general. A risk of investing in smaller, emerging companies is that they
often are at an earlier stage of development and therefore have limited product
lines, market access for such products, financial resources and depth in
management than larger, more established companies. In addition, certain smaller
issuers may have a higher probability of facing difficulties in obtaining the
capital necessary to continue in operation and may go into bankruptcy, which
could result in a complete loss of an investment. Smaller companies also may be
less significant factors within their industries and may have difficulty
withstanding competition from larger companies. While smaller companies may be
subject to these additional risks, they may also realize more substantial growth
than larger, more established companies.
 
Foreign Securities--Each Portfolio (other than the International Equity
Portfolio) is authorized to invest up to 30% of its total assets, and the
International Equity Portfolio invests without limitation, in foreign
securities. Each Portfolio may also invest in U.S. dollar denominated securities
of foreign issuers, including ADRs, as well as EDRs, GDRs or other similar
securities convertible into securities of foreign issuers. These securities may
not necessarily be denominated in the same currency as the securities into which
they may be converted. Each Portfolio also may invest in securities denominated
in European Currency Units (ECUs). An ECU is a 'basket' consisting of specified
amounts of currencies of certain of the twelve member states of the European
Community. In addition, each Portfolio may invest in securities denominated in
other currency 'baskets.' Each Portfolio may also seek to gain exposure to
certain foreign markets, including developing countries or emerging markets,
where direct investment may be difficult or impracticable, through investment in
domestic closed-end mutual funds which invest predominately in such markets. See
the Statement of Additional Information for a further discussion of foreign
securities.
 
Risks of Foreign Securities.  Foreign investments may be affected favorably or
unfavorably by changes in currency rates and exchange-control regulations and
costs will be incurred in connection with conversions between various
currencies. The value of a security may fluctuate as a result of currency
exchange rates in a manner unrelated to the underlying value of the security.
There may be less publicly available information about a foreign company than
about a U.S. company, and foreign companies may not be subject to uniform
accounting, auditing

and financial reporting standards and requirements comparable to those
applicable to U.S. companies.
 
Securities of some foreign companies may be less liquid or more volatile than
securities of U.S. companies, and foreign brokerage commissions and custodian
fees are generally higher than in the U.S. In addition, there is generally less
governmental regulation of stock exchanges, brokers and listed companies abroad
than in the U.S. Investments in foreign securities may also be subject to other
risks, different from those affecting U.S. investments, including local
political or economic developments, expropriation or nationalization of assets,
confiscatory taxation and imposition of withholding taxes on income from sources
within such countries.
 
Emerging Markets.  Investments may be made from time to time in issuers
domiciled in, or government securities of, developing countries or emerging
markets. Although there is no universally accepted definition, a developing
country is generally considered to be a country in the initial stages of its
industrialization cycle with a low per capita gross national product. Historical
experience indicates that the markets of developing countries or emerging
markets have been more volatile than the markets of developed countries;
however, such markets can provide higher rates of return to investors.
Investment in an emerging market country may involve certain risks, including a
less diverse and mature economic structure, a less stable political system, an
economy based on only a few industries or dependent on international aid or
development assistance, the vulnerability to local or global trade conditions,
extreme debt burdens, or volatile inflation rates. See 'Foreign Investment
Companies' below for a discussion of investing in investment companies which
invest in emerging markets.
 
Foreign Currency Transactions.  Each Portfolio has the ability to hold a portion
of its assets in foreign currencies and to enter into forward foreign currency
exchange contracts. It may also purchase and sell exchange-traded futures
contracts relating to foreign currency and purchase and sell put and call
options on currencies and futures contracts.
 
Each Portfolio may enter into forward foreign currency exchange contracts to
reduce the risks of fluctuations in exchange rates; however, these contracts
cannot eliminate all such risks and do not eliminate fluctuations in the prices
of the Portfolio's portfolio securities.
 
Each Portfolio may purchase and write put and call options on currencies for the
purpose of protecting against declines in the U.S. dollar value of foreign
portfolio securities and against increases in the U.S. dollar cost of foreign
securities to be acquired. The purchase of an option on currency may constitute
an effective hedge against exchange rate fluctuations; however, in the event of
exchange rate movements adverse to a Portfolio's position, the Portfolio may
forfeit the entire amount of the premium plus related transaction costs. As with
other kinds of option transactions, however, the writing of an option on
currency will constitute only a partial hedge, up to the amount of the premium
received, and a Portfolio could be required to purchase or sell currencies at
disadvantageous exchange rates, thereby incurring losses.
 
Each Portfolio may enter into forward foreign currency exchange contracts,
currency options and currency swaps for non-hedging purposes when an Adviser
anticipates that a foreign currency will appreciate or depreciate in value, but
securities denominated in that currency do not present attractive investment
opportunities or are not included in such portfolio. The Portfolio may use
currency contracts and options to cross-hedge, which involves selling or
purchasing instruments in one currency to hedge against changes in exchange
rates for a different currency with a pattern of correlation. To limit any
leverage in connection with currency contract transactions for hedging or
non-hedging purposes, a Portfolio will segregate cash or liquid securities in an
amount sufficient to meet its payment obligations in these transactions or
otherwise 'cover' the obligation. Initial margin deposits made in connection
with currency futures transactions or premiums paid for currency options traded
over-the-counter or on a commodities exchange may each not exceed 5% of a
Portfolio's total net assets in the case of non-bona fide hedging transactions.
 
Each Portfolio may enter into currency swaps. Currency swaps involve the
exchange by a Portfolio with another party of their respective rights to make or
receive payments in specified currencies. Currency swaps usually involve the
delivery of the entire principal value of one designated currency in exchange
for the other designated currency. Therefore, the entire principal value of a
currency swap is subject to the risk that the other party to the swap will
default on its contractual delivery obligations. A Portfolio will maintain in a
segregated account with its custodian, cash or liquid securities equal to the
net amount, if any, of the excess of the Portfolio's obligations over its
entitlements with respect to swap

<PAGE>

STYLE SELECT SERIES(Registered)

transactions. To the extent that the net amount of a swap is held in a
segregated account consisting of cash or liquid securities, the Fund believes
that swaps do not constitute senior securities under the 1940 Act and,
accordingly, they will not be treated as being subject to the Portfolio's
borrowing restrictions. The use of currency swaps is a highly specialized
activity which involves investment techniques and risks different from those
associated with ordinary portfolio securities transactions. If an Adviser is
incorrect in its forecasts of market values and currency exchange rates, the
investment performance of a Portfolio would be less favorable than it would have
been if this investment technique were not used.
 
Foreign Investment Companies--Each Portfolio may invest in domestic closed-end
investment companies which invest in certain foreign markets, including
developing countries or emerging markets. The Large-Cap Growth, Aggressive
Growth and International Equity Portfolios may also invest in foreign investment
companies which invest in such markets. Some of the countries in which the
Portfolios invest may not permit direct investment by foreign investors such as
the Portfolios. Investments in such countries may only be permitted through
foreign government-approved or authorized investment vehicles, which may include
other investment companies. In addition, it may be less expensive and more
expedient for the Portfolios to invest in investment companies in a country that
permits direct foreign investment. Investing through such vehicles may involve
frequent or layered fees or expenses and may also be subject to limitation under
the 1940 Act. Under the 1940 Act, a fund may invest up to 10% of its assets in
shares of other investment companies and up to 5% of its assets in any one
investment company as long as the investment does not represent more than 3% of
the voting stock of the acquired investment company. The Portfolios do not
intend to invest in such investment companies unless, in the judgment of the
Advisers, the potential benefits of such investments justify the payment of any
associated fees and expenses. See 'Foreign Securities' and 'Emerging Markets'
above and the Statement of Additional Information.
 
Fixed Income Securities--Fixed income securities are broadly characterized as
those that provide for periodic payments to the holder of the security at a
stated rate. Most fixed income securities, such as bonds, represent indebtedness
of the issuer and provide for repayment of principal at a stated time in the
future. Others do not provide for repayment of a principal amount, although they
may represent a priority over common stockholders in the event of the issuer's
liquidation. Many fixed income securities are subject to scheduled retirement,
or may be retired or 'called' by the issuer prior to their maturity dates. The
interest rate on certain fixed income securities, known as 'variable rate
obligations,' is determined by reference to or is a percentage of an objective
standard, such as a bank's prime rate, the 90-day Treasury bill rate, or the
rate of return on commercial paper or bank certificates of deposit, and is
periodically adjusted. Certain variable rate obligations may have a demand
feature entitling the holder to resell the securities at a predetermined amount.
The interest rate on certain fixed income securities, called 'floating rate
instruments,' changes whenever there is a change in a designated base rate.
 
The market values of fixed income securities tend to vary inversely with the
level of interest rates--when interest rates rise, their values will tend to
decline; when interest rates decline, their values generally will tend to rise.
The potential for capital appreciation with respect to variable rate obligations
or floating rate instruments will be less than with respect to fixed-rate
obligations. Long-term instruments are generally more sensitive to these changes
than short-term instruments. The market value of fixed income securities and
therefore their yield is also affected by the perceived ability of the issuer to
make timely payments of principal and interest.
 
U.S. Government Securities--Securities guaranteed by the U.S. government include
the following: (1) direct obligations of the U.S. Treasury (such as Treasury
bills, notes and bonds) and (2) federal agency obligations guaranteed as to
principal and interest by the U.S. Treasury (such as Government National
Mortgage Association certificates and Federal Housing Administration
debentures). For these securities, the payment of principal and interest is
unconditionally guaranteed by the U.S. government. They are of the highest
possible credit quality. These securities are subject to variations in market
value due to fluctuations in interest rates, but if held to maturity, are
guaranteed by the U.S. government to be paid in full.
 
Securities issued by U.S. government instrumentalities and certain federal
agencies are neither direct obligations of, nor are they guaranteed by, the U.S.
Treasury. However, they involve federal sponsorship in one way or another. For
example, some are

<PAGE>

                                                                              41

                                                STYLE SELECT SERIES(Registered)

backed by specific types of collateral; some are supported by the issuer's right
to borrow from the Treasury; some are supported by the discretionary authority
of the Treasury to purchase certain obligations of the issuer; and others are
supported only by the credit of the issuing government agency or
instrumentality. These agencies and instrumentalities include, but are not
limited to, the Federal National Mortgage Association, the Federal Home Loan
Mortgage Corporation, Federal Land Banks, Farmers Home Administration, Central
Bank for Cooperatives, Federal Intermediate Credit Banks and Federal Home Loan
Banks.
 
Corporate Debt Instruments--These instruments, such as bonds, represent the
obligation of the issuer to repay a principal amount of indebtedness at a stated
time in the future and, in the usual case, to make periodic interim payments of
interest at a stated rate.
 
Investment Grade--A designation applied to intermediate and long-term corporate
debt securities rated within the highest four rating categories assigned by S&P
(AAA, AA, A or BBB) or by Moody's (Aaa, Aa, A or Baa), or, if unrated,
considered by the Adviser to be of comparable quality. The ability of the issuer
of an investment grade debt security to pay interest and to repay principal is
considered to vary from extremely strong (for the highest ratings) through
adequate (for the lowest ratings given above), although the lower-rated
investment grade securities may be viewed as having speculative elements as
well.
 
High-Yield, High-Risk Bonds--A designation applied to intermediate and long-term
corporate debt securities that are not investment grade; commonly referred to as
'junk bonds.' These include bonds rated below BBB by S&P, or Baa by Moody's, or
which are unrated but considered by the Adviser to be of equivalent quality.
These securities are considered speculative. See the Statement of Additional
Information for a complete description of bond ratings.
 
The Mid-Cap Growth Portfolio and Large-Cap Value Portfolio may invest in debt
securities rated as low as 'BBB' by S&P, 'Baa' by Moody's, or unrated securities
determined by the Adviser to be of comparable quality. The Large-Cap Growth,
Aggressive Growth, Large-Cap Blend, Value, Small-Cap Value and International
Equity Portfolios may invest in debt securities rated below investment grade
(i.e., below 'BBB' by S&P, or below 'Baa' by Moody's), or if unrated, determined
by the Adviser to be of equivalent quality.
 
Risk Factors Relating to High-Yield, High-Risk Bonds--High-yield, high-risk
bonds are subject to greater fluctuations in value than are higher rated bonds
because the values of high-yield bonds tend to reflect short-term corporate,
economic and market developments and investor perceptions of the issuer's credit
quality to a greater extent. Although under normal market conditions longer-term
securities yield more than shorter-term securities, they are subject to greater
price fluctuations. Fluctuations in the value of a Portfolio's investments will
be reflected in its net asset value per share. The growth of the high-yield bond
market paralleled a long economic expansion, followed by an economic downturn
which severely disrupted the market for high-yield bonds and adversely affected
the value of outstanding bonds and the ability of the issuers to repay principal
and interest. The economy may affect the market for high-yield bonds in a
similar fashion in the future including an increased incidence of defaults on
such bonds. From time to time, legislation may be enacted which could have a
negative effect on the market for high-yield bonds.
 
High-yield bonds present the following risks:
 
Sensitivity to Interest Rate and Economic Changes--High-yield, high-risk bonds
are very sensitive to adverse economic changes and corporate developments.
During an economic downturn or substantial period of rising interest rates,
highly leveraged issuers may experience financial stress that would adversely
affect their ability to service their principal and interest payment
obligations, to meet projected business goals and to obtain additional
financing. If the issuer of a bond defaulted on its obligations to pay interest
or principal or entered into bankruptcy proceedings, a Portfolio may incur
losses or expenses in seeking recovery of amounts owed to it. In addition,
periods of economic uncertainty and changes can be expected to result in
increased volatility of market prices (and therefore yields) of high-yield bonds
and the Portfolio's net asset value.
 
Payment Expectations--High-yield, high-risk bonds may contain redemption or call
provisions. If an issuer exercised these provisions in a declining interest-rate
market, an Adviser would have to replace the security with a lower-yielding
security, resulting in a decreased return for investors. Conversely, a
high-yield bond's value will decrease in a rising interest rate market, as will
the value of the Portfolio's assets. If the Portfolio experiences unexpected net
redemptions, this may force it to sell high-yield bonds without regard to their
investment merits, thereby decreasing the asset base upon

<PAGE>

which expenses can be spread and possibly reducing the Portfolio's rate of
return.
 
Liquidity and Valuation--There may be little trading in the secondary market for
particular bonds, which may affect adversely a Portfolio's ability to value
accurately or dispose of such bonds.
 
Under such circumstances, the task of accurate valuation becomes more difficult
and judgment would play a greater role due to the relative lack of reliable and
objective data. Adverse publicity and investor perceptions, whether or not based
on fundamental analysis, may decrease the values and liquidity of high-yield
bonds, especially in a thinly traded market.
 
Each Adviser attempts to reduce these risks through diversification of the
assets under its control and by credit analysis of each issuer, as well as by
monitoring broad economic trends and corporate and legislative developments. If
a high-yield bond previously acquired by a Portfolio is downgraded, the
Advisers, as appropriate, will evaluate the security and determine whether to
retain or dispose of it.
 
Asset-Backed Securities--These securities represent an interest in a pool of
consumer or other types of loans. Payments of principal and interest on the
underlying loans are passed through to the holders of asset-backed securities
over the life of the securities. See the Statement of Additional Information for
a further discussion of these types of securities.
 
Zero Coupon Bonds, Step-Coupon Bonds, Deferred Interest Bonds and PIK
Bonds.  Fixed income securities in which a Portfolio may invest also include
zero coupon bonds, step-coupon bonds, deferred interest bonds and bonds on which
the interest is payable in kind ('PIK bonds'). Zero coupon and deferred interest
bonds are debt obligations issued or purchased at a significant discount from
face value. A step-coupon bond is one in which a change in interest rate is
fixed contractually in advance. PIK bonds are debt obligations which provide
that the issuer thereof may, at its option, pay interest on such bonds in cash
or in the form of additional debt obligations. Such investments may experience
greater volatility in market value due to changes in interest rates and other
factors than debt obligations which make regular payments of interest. A
Portfolio will accrue income on such investments for tax and accounting
purposes, as required, which is distributable to shareholders and which, because
no cash is received at the time of accrual, may require the liquidation of other
portfolio securities under disad-vantageous circumstances to satisfy the
Portfolio's distribution obligations.
 
REITs--The Large-Cap Blend and each of the Value Portfolios may invest in Real
Estate Investment Trusts ('REITs'), which are trusts that invest primarily in
commercial real estate or real estate related loans. The value of an interest in
a REIT may be affected by the value and the cash flows of the properties owned
or the quality of the mortgages held by the trust.
 
Short-Term and Temporary Defensive Investments--In addition to their primary
investments, each Portfolio may also invest up to 25% of its total assets in
both U.S. and non-U.S. dollar denominated money market instruments (a) for
liquidity purposes (to meet redemptions and expenses) or (b) to generate a
return on idle cash held in a Portfolio's portfolio during periods when an
Adviser is unable to locate favorable investment opportunities. For temporary
defensive purposes, each Portfolio may invest up to 100% of its total assets in
cash and short-term fixed income securities, including corporate debt
obligations and money market instruments rated in one of the two highest
categories by a nationally recognized statistical rating organization (or
determined by the Adviser to be of equivalent quality). In addition, Janus and
Neuberger&Berman may invest idle cash of the assets under their control in money
market mutual funds that they manage. Such an investment may entail additional
fees. See the Statement of Additional Information for a description of short-
term debt securities and the Appendix to the Statement of Additional Information
for a description of securities ratings.
 
Repurchase Agreements--Under these types of agreements, a Portfolio buys a
security and obtains a simultaneous commitment from the seller to repurchase the
security at a specified time and price. The seller must maintain appropriate
collateral with the Fund's custodian (or at an appropriate sub-custodian in the
case of tri- or quad-party repurchase agreements). A Portfolio will only enter
into repurchase agreements involving securities in which it could otherwise
invest and with selected banks and securities dealers whose financial condition
is monitored by the Adviser, subject to the guidance of the Directors. If the
seller under the repurchase agreement defaults, the Portfolio may incur a loss
if the value of the collateral securing the repurchase agreement has declined,
and may incur disposition costs in connection with liquidating the collateral.
If bankruptcy proceedings are commenced with

<PAGE>

                                                                              43

                                                STYLE SELECT SERIES(Registered)

respect to the seller, realization of the collateral by the Portfolio may be
delayed or limited.
 
Hedging and Income Enhancement Strategies--Each Portfolio may write covered
calls to enhance income. After writing such a covered call up to 25% of a
Portfolio's total assets may be subject to calls. All such calls written by a
Portfolio must be 'covered' while the call is outstanding (i.e., the Portfolio
must own the securities subject to the call or other securities acceptable for
applicable escrow requirements). For hedging purposes or income enhancement,
each Portfolio may use interest rate futures, and stock and bond index futures,
including futures on U.S. government securities (together, 'Futures'); forward
contracts on foreign currencies; and call and put options on equity and debt
securities, Futures, stock and bond indices and foreign currencies (all of the
foregoing are referred to as 'Hedging Instruments'). All puts and calls on
securities, interest rate futures or stock and bond index futures or options on
such Futures purchased or sold by a Portfolio will be listed on a national
securities or commodities exchange or on U.S. over-the-counter markets.
 
Each Portfolio may use spread transactions for any lawful purpose consistent
with the Portfolio's investment objective such as hedging or managing risk, but
not for speculation. A Portfolio may purchase covered spread options from
securities dealers. Such covered spread options are not presently
exchange-listed or exchange-traded. The purchase of a spread option gives a
Portfolio the right to put, or sell, a security that it owns at a fixed dollar
spread or fixed yield spread in relationship to another security that the
Portfolio does not own, but which is used as a benchmark. The risk to a
Portfolio in purchasing covered spread options is the cost of the premium paid
for the spread option and any transaction costs. In addition, there is no
assurance that closing transactions will be available. The purchase of spread
options will be used to protect a Portfolio against adverse changes in
prevailing credit quality spreads, i.e., the yield spread between high quality
and lower quality securities. Such protection is only provided during the life
of the spread option.
 
Special Risks of Hedging and Income Enhancement Strategies.  Participation in
the options or Futures markets and in currency exchange transactions involves
investment risks and transaction costs to which a Portfolio would not be subject
absent the use of these strategies. If the Advisers' predictions of movements in
the direction of the securities, foreign currency and interest rate markets are
inaccurate, the adverse consequences to a Portfolio may leave the Portfolio in a
worse position than if such strategies were not used. Risks inherent in the use
of options, foreign currency and Futures contracts and options on Futures
contracts include (1) dependence on the Advisers' ability to predict correctly
movements in the direction of interest rates, securities prices and currency
markets; (2) imperfect correlation between the price of options and Futures
contracts and options thereon and movements in the prices of the securities or
currencies being hedged; (3) the fact that skills needed to use these strategies
are different from those needed to select portfolio securities; (4) the possible
absence of a liquid secondary market for any particular instrument at any time;
(5) the possible need to defer closing out certain hedged positions to avoid
adverse tax consequences; and (6) the possible inability of the Portfolio to
purchase or sell a portfolio security at a time that otherwise would be
favorable for it to do so, or the possible need for the Portfolio to sell a
portfolio security at a disadvantageous time, due to the need for the Portfolio
to maintain 'cover' or to segregate securities in connection with hedging
transactions. A transaction is 'covered' when the Portfolio owns the security
subject to the option on such security, or some other security acceptable for
applicable segregation requirements. See the Statement of Additional Information
for further information concerning income enhancement and hedging strategies and
the regulation requirements relating thereto.
 
Illiquid and Restricted Securities--No more than 15% of the value of a
Portfolio's net assets may be invested in securities which are illiquid,
including repurchase agreements that have a maturity of longer than seven days,
interest rate swaps, currency swaps, caps, floors and collars. For this purpose,
not all securities which are restricted are deemed to be illiquid. For example,
restricted securities which the Board of Directors, or the Adviser pursuant to
guidelines established by the Board of Directors, has determined to be
marketable, such as securities eligible for sale under Rule 144A promulgated
under the Securities Act of 1933, as amended, or certain private placements of
commercial paper issued in reliance on an exemption from such Act pursuant to
Section 4(2) thereof, may be deemed to be liquid for purposes of this
restriction. This investment practice could have the effect of increasing the
level of illiquidity in the Portfolio to the extent that qualified institutional
buyers (as defined in Rule 144A) become for a time uninterested in purchasing
these

<PAGE>

44

STYLE SELECT SERIES(Registered)

restricted securities. In addition, a repurchase agreement which by its terms
can be liquidated before its nominal fixed-term on seven days or less notice is
regarded as a liquid instrument. Subject to the applicable limitation on
illiquid securities investments, a Portfolio may acquire securities issued by
the U.S. government, its agencies or instrumentalities in a private placement.
See 'Illiquid Securities' in the Statement of Additional Information for a
further discussion of investments in such securities.
 
Hybrid Instruments--These instruments, including indexed or structured
securities, can combine the characteristics of securities, futures, and options.
For example, the principal amount, redemption, or conversion terms of a security
could be related to the market price of some commodity, currency, or securities
index. Such securities may bear interest or pay dividends at below market (or
even relatively nominal) rates. Under certain conditions, the redemption value
of such an investment could be zero.
 
Borrowing--As a matter of fundamental policy, each Portfolio is authorized to
borrow up to 33 1/3% of its total assets from banks for temporary or emergency
purposes. In seeking to enhance investment performance, each Portfolio may
borrow money for investment purposes and may pledge assets to secure such
borrowings. This is the speculative factor known as leverage. This practice may
help increase the net asset value of the assets of a Portfolio in an amount
greater than would otherwise be the case when the market values of the
securities purchased through borrowing increase. In the event the return on an
investment of borrowed monies does not fully recover the costs of such
borrowing, the value of the Portfolio's assets would be reduced by a greater
amount than would otherwise be the case. The effect of leverage will therefore
tend to magnify the gains or losses to the Portfolio as a result of investing
the borrowed monies. During periods of substantial borrowings, the value of the
Portfolio's assets would be reduced due to the added expense of interest on
borrowed monies. Each Portfolio is authorized to borrow, and to pledge assets to
secure such borrowings, up to the maximum extent permissible under the 1940 Act
(i.e., presently 50% of net assets). The time and extent to which a Portfolio
may employ leverage will be determined by the Adviser in light of changing facts
and circumstances, including general economic and market conditions, and will be
subject to applicable lending regulations of the Board of Governors of the
Federal Reserve Board.
 
Securities Lending--Each Portfolio may lend portfolio securities in amounts up
to 33 1/3% of its respective total assets to brokers, dealers and other
financial institutions, provided such loans are callable at any time by the
Portfolio and are at all times secured by cash or equivalent collateral. By
lending its portfolio securities, a Portfolio will receive income while
retaining the securities' potential for capital appreciation. As with any
extensions of credit, there are risks of delay in recovery and, in some cases,
even loss of rights in the collateral should the borrower of the securities fail
financially. However, these loans of portfolio securities will be made only to
firms deemed by the Adviser to be creditworthy. The proceeds of such loans will
be invested in high-quality short-term debt securities, including repurchase
agreements.
 
When-Issued, Delayed Delivery and Forward Transactions--These generally involve
the purchase or sale of a security with payment and delivery at some time in the
future--i.e., beyond normal settlement. A Portfolio does not earn interest on
securities purchased in this manner until settlement and bears the risk of
market value fluctuations in between the purchase and settlement dates. New
issues of stocks and bonds, private placements and U.S. government securities
may be sold in this manner. One form of when-issued or delayed delivery security
that each Portfolio may purchase is a 'to be announced' or 'TBA' mortgage-backed
security. A TBA mortgage-backed security transaction arises when a
mortgage-backed security is purchased or sold with the specific pools to be
announced on a future settlement date.
 
Short Sales--Each Portfolio may sell a security it does not own in anticipation
of a decline in the market value of that security (short sales). To complete
such a transaction, a Portfolio must borrow the security to make delivery to the
buyer. The Portfolio then is obligated to replace the security borrowed by
purchasing it at market price at the time of replacement. The price at such time
may be more or less than the price at which the security was sold by the
Portfolio. Until the security is replaced, the Portfolio is required to pay to
the lender any dividends or interest which accrue during the period of the loan.
To borrow the security, the Portfolio also may be required to pay a premium,
which would increase the cost of the security sold. The proceeds of the short
sale will be retained by the broker, to the extent necessary to meet margin
requirements, until the short position is closed out. Until the Portfolio
replaces a borrowed security, the Portfolio will

<PAGE>
                                                                              45

                                                STYLE SELECT SERIES(Registered)

maintain daily a segregated account, containing cash or liquid securities, at
such a level that (i) the amount deposited in the account plus the amount
deposited with the broker as collateral will equal the current value of the
security sold short and (ii) the amount deposited in the segregated account plus
the amount deposited with the broker as collateral will not be less than the
market value of the security at the time it was sold short. A Portfolio will
incur a loss as a result of the short sale if the price of the security
increases between the date of the short sale and the date on which the Portfolio
replaces the borrowed security. A Portfolio will realize a gain if the security
declines in price between those dates. This result is the opposite of what one
would expect from a cash purchase of a long position in a security. The amount
of any gain will be decreased, and the amount of any loss increased, by the
amount of any premium, dividends or interest the Portfolio may be required to
pay in connection with a short sale.
 
Each Portfolio may make 'short sales against the box.' A short sale is against
the box to the extent that the Portfolio contemporaneously owns, or has the
right to obtain without payment, securities identical to those sold short. A
Portfolio generally will recognize gain (but not loss) upon a short sale against
the box for Federal income tax purposes. A Portfolio may not enter into a short
sale, including a short sale against the box, if, as a result, more than 25% of
its net assets would be subject to such short sales.

 
Special Situations--A 'special situation' arises when, in the opinion of the
Adviser, the securities of a particular issuer will be recognized and appreciate
in value due to a specific development with respect to that issuer. Developments
creating a special situation might include, among others, a new product or
process, a technological breakthrough, a management change or other
extraordinary corporate event, or differences in market supply of and demand for
the security. Investment in special situations may carry an additional risk of
loss in the event that the anticipated development does not occur or does not
attract the expected attention.
 
Future Developments--Each Portfolio may invest in securities and other
instruments which do not presently exist but may be developed in the future,
provided that each such investment is consistent with the Portfolio's investment
objectives, policies and restrictions and is otherwise legally permissible under
federal and state laws. The Prospectus will be amended or supplemented as
appropriate to discuss any such new investments.
 
See the Statement of Additional Information for further information concerning
these and other types of securities and investment techniques in which the
Portfolio may from time to time invest, including dollar rolls, standby
commitments and reverse repurchase agreements.

- --------------------------------------------------------------------------------
 
Directors.  The Directors of the Fund are responsible for the overall

State of Maryland.
 
SunAmerica Asset Management Corp.  SunAmerica is an indirect wholly owned
subsidiary of SunAmerica Inc., an investment-grade financial services company
which, as of March 31, 1998, held more than $55 billion in assets. SunAmerica
Inc.'s principal executive offices are located at 1 SunAmerica Center, Los
Angeles, CA 90067-6022. In addition to managing the Fund and serving as an
Adviser to the Aggressive Growth Portfolio and Large-Cap Blend Portfolio,
SunAmerica serves as adviser, manager and/or administrator for Anchor Pathway
Fund, Anchor Series Trust, Seasons Series Trust, SunAmerica Equity Funds,
SunAmerica Income Funds, SunAmerica Money Market Funds, Inc., and SunAmerica
Series Trust. SunAmerica managed, advised and/or administered assets in excess
of $14.5 billion as of March 31, 1998 for investment companies, individuals,
pension accounts, and corporate and trust accounts.

 
SunAmerica selects the Advisers for and/or manages the investments of each
Portfolio, provides various administrative services and supervises the
Portfolio's daily business affairs, subject to general review by the Directors.
The Investment Advisory and Management Agreement entered into between SunAmerica
and the Fund, on behalf of each Portfolio (the 'Management Agreement')
authorizes

SunAmerica to manage the assets of each Portfolio and/or to retain the Advisers
to do so. SunAmerica monitors the activities of the Advisers, and from time to
time will recommend the replacement of an Adviser on the basis of investment
performance, style drift, or other considerations.
 
The annual rate of the investment advisory fee payable to SunAmerica that
applies to each of the Growth Portfolios, Large-Cap Blend Portfolio and Value
Portfolios is 1.00% of Assets. The annual rate of the investment advisory fee
payable to SunAmerica that applies to the International Equity Portfolio is
1.10% of Assets. The term 'Assets' means the average daily net assets of the
Portfolio. The investment advisory fees are accrued daily and paid monthly, and
may be higher than those charged to other funds.
 
For the fiscal year ended October 31, 1997, each Portfolio paid SunAmerica a fee
equal to the following percentages of average daily net assets: Large-Cap Growth
Portfolio 1.00%; Mid-Cap Growth Portfolio 1.00%; Aggressive Growth Portfolio
1.00%; Large-Cap Blend Portfolio 1.00%; Large-Cap Value Portfolio 1.00%; Value
Portfolio 1.00%; Small-Cap Value Portfolio 1.00%; and International Equity
Portfolio 1.10%. SunAmerica has voluntarily agreed to waive fees or reimburse
expenses, if necessary, to keep operating expenses at or below an annual rate of
1.78% of the Assets of Class A shares and 2.43% of the Assets of Class B and
Class C shares for each Portfolio (other than the International Equity
Portfolio) and 2.03% of the Assets of Class A shares and 2.68% of the Assets of
Class B and Class C shares for the International Equity Portfolio. SunAmerica
also may voluntarily waive or reimburse additional amounts to increase the
investment return to a Portfolio's investors. SunAmerica may terminate all such
waivers and/or reimbursements at any time. Further, any waivers or
reimbursements made by SunAmerica with respect to a Portfolio are subject to
recoupment from that Portfolio within the following two years, provided that the
Portfolio is able to effect such payment to SunAmerica and remain in compliance
with the foregoing expense limitations.
 
The Advisers.  The organizations described below act as Advisers to the
respective Portfolio pursuant to agreements with SunAmerica (each, a
'Subadvisory Agreement' and collectively the 'Subadvisory Agreements'). The
duties of each Adviser include furnishing continuing advice and recommendations
to the relevant portion of the respective Portfolio regarding securities to be
purchased and sold. Each Adviser, therefore, generally formulates the continuing
program for management of the Assets under its control consistent with the
Portfolio's investment objectives and the investment policies established by the
Board. Because each Adviser manages its portion of its respective Portfolio
independently of the Portfolio's other Advisers, the same security may be held
in two different portions of the same Portfolio, or may be acquired for one
portion of the Portfolio at the time that the Adviser to another portion of the
Portfolio deems it appropriate to dispose of the security from that other
portion. Under some market conditions, one or more of the Advisers may believe
that temporary, defensive investments in short-term instruments or cash are
appropriate when another Adviser or Advisers believe continued exposure to the
equity markets is appropriate for their portions of the Portfolio.
 
Each of the Advisers (other than SunAmerica) is independent of SunAmerica and
discharges its responsibilities subject to the oversight and supervision of
SunAmerica, which pays the Advisers' fees. Each Adviser is paid monthly by
SunAmerica a fee equal to a percentage of the Assets of the Portfolio allocated
to the Adviser. The aggregate annual rates, as a percentage of daily net assets,
of the fees payable by SunAmerica to the Advisers for each Portfolio may vary
according to the level of Assets of each Portfolio. For the fiscal year ended
October 31, 1997, SunAmerica paid fees to the Advisers equal to the following
aggregate annual rates, expressed as a percentage of the Assets of each
Portfolio: Large-Cap Growth Portfolio, 0.48%; Mid-Cap Growth Portfolio, 0.50%;
Aggressive Growth Portfolio, 0.37%; Large-Cap Blend Portfolio, 0.32%; Large-Cap
Value Portfolio, 0.41%; Value Portfolio, 0.50%; Small-Cap Value Portfolio,
0.55%; and International Equity Portfolio, 0.65%.
 
SunAmerica may terminate any Subadvisory Agreement without shareholder approval.
Moreover, SunAmerica has received an exemptive order from the Securities and
Exchange Commission which permits SunAmerica, subject to certain conditions, to
enter into Subadvisory Agreements relating to the Fund with Advisers approved by
the Board without obtaining shareholder approval. The exemptive order also
permits SunAmerica, subject to the approval of the Board but without shareholder
approval, to employ new Advisers for new or existing Portfolios, change the
terms of particular

Agreement. Shareholders of a Portfolio have the right to terminate a Subadvisory

shareholders the Advisers' fees only in the aggregate for each Portfolio.

The Distributor.  SunAmerica Capital Services, Inc. (the 'Distributor'), an

Distributor and the Fund on behalf of each Portfolio. The Distributor receives
all initial and deferred sales charges in connection with the sale of Fund
shares, all or a portion of which it may reallow to other broker-dealers. The
Distributor and other broker-dealers pay commissions to salespersons, as well as
the cost of printing and mailing prospectuses to potential investors and of any
advertising expenses incurred by them in connection with their distribution of
Portfolio shares.
 
The Distributor, at its expense, may from time to time provide additional
compensation to broker-dealers (including in some instances affiliates of the
Distributor) in connection with sales of shares of the Fund. Such compensation
may include (i) full re-allowance of the front-end sales charge on Class A
shares; (ii) additional compensation with respect to the sale of Class A, Class
B or Class C shares; or (iii) financial assistance to broker-dealers in
connection with conferences, sales or training programs for their employees,
seminars for the public, advertising campaigns regarding one or more of the
Portfolios, and/or other broker-dealer sponsored special events. In some
instances, this compensation will be made available only to certain
broker-dealers whose representatives have sold a significant amount of shares of
the Fund. Compensation may also include payment for travel expenses, including
lodging, incurred in connection with trips taken by invited registered
representatives for meetings or seminars of a business nature. In addition, the
following types of non-cash compensation may be offered through sales contests:
(i) travel mileage on major air carriers; (ii) tickets for entertainment events
(such as concerts or sporting events); or (iii) merchandise (such as clothing,
trophies, clocks, pens or other electronic equipment). Broker-dealers may not
use sales of the Funds' shares to qualify for this compensation to the extent
receipt of such compensation may be prohibited by the laws of any state or any
self-regulatory agency, such as, for example, the National Association of
Securities Dealers, Inc. Dealers who receive bonuses or other incentives may be
deemed to be underwriters under the Securities Act of 1933.

Certain laws and regulations limit the ability of banks and other depository
institutions to underwrite and distribute securities. However, in the opinion of
SunAmerica based upon the advice of counsel, these laws and regulations do not
prohibit such depository institutions from providing other services to
investment companies of the type contemplated by the Distribution Plans (as
described below). The Directors will consider appropriate modifications to the
operations of the Portfolios, including discontinuance of payments under the
Distribution Plans to banks and other depository institutions, in the event such
institutions can no longer provide the services called for under their
agreements. Banks and other financial services firms may be subject to various
state laws regarding services described, and may be required to register as
dealers pursuant to state law.
 
Distribution Plans.  Rule 12b-1 under the 1940 Act permits an investment company
directly or indirectly to pay expenses associated with the distribution of its
shares in accordance with a plan adopted by the investment company's board of
directors and approved by its shareholders. Pursuant to such rule, the Directors
and the shareholders of each class of shares of each Portfolio have adopted
distribution plans hereinafter referred to as the 'Class A Plan,' the 'Class B
Plan' and the 'Class C Plan,' and collectively as the 'Distribution Plans.' In
adopting each Distribution Plan, the Directors determined that there was a
reasonable likelihood that each such Plan would benefit the Portfolios and the
shareholders of each respective class. The sales charge and distribution fees of
a particular class will not be used to subsidize the sale of shares of any other
class.
 
Under the Class A Plan, the Distributor may receive payments from a Portfolio at
an annual rate of up to 0.10% of average daily net assets of such Portfolio's
Class A shares to compensate the Distributor and certain securities firms for
providing sales and promotional activities for distributing that class of
shares. Under the Class B and Class C Plans, the Distributor may receive
payments from a Portfolio at the annual rate of up to 0.75% of the average daily
net assets of such Portfolio's Class B and Class C shares, respectively, to
compensate the Distributor and certain securities firms for providing sales and
promotional activities for distributing each such class of shares. The
distribution costs for which the Distributor may be reimbursed out of such
distribution fees include fees paid to broker-dealers that have sold Portfolio
shares, commissions, and other expenses such as those incurred for sales
literature, prospectus printing and distribution and compensa-tion to
wholesalers. It is possible that in any given year the amount paid to the
Distributor under one or more of the Distribution Plans may exceed the
Distributor's distribution costs as described above. The Distribution Plans
provide that each class of shares of each Portfolio may also pay the Distributor
an account maintenance and service fee of up to 0.25% of the aggregate average
daily net assets of such class of shares for payments to broker-dealers
for providing continuing account maintenance. In this regard, some payments are
used to compensate broker-dealers with account maintenance and service fees in
an amount up to 0.25% per year of the assets maintained in a Portfolio by their
customers.
 
For the fiscal year ended October 31, 1997, under the Class A Plan, each
Portfolio paid the Distributor a fee equal to the following percentages of
average daily net assets: Large-Cap Growth Portfolio 0.35%; Mid-Cap Growth
Portfolio 0.35%; Aggressive Growth Portfolio 0.35%; Large-Cap Blend Portfolio
0.35%; Large-Cap Value Portfolio 0.35%; Value Portfolio 0.35%; Small-Cap Value
Portfolio 0.35%; and International Equity Portfolio 0.35%. For the fiscal year
ended October 31, 1997, under the Class B and Class C Plans, each Portfolio paid
the Distributor a fee equal to the following percentages of average daily net
assets: Large-Cap Growth Portfolio, 1.00%; Mid-Cap Growth Portfolio 1.00%;
Aggressive Growth Portfolio 1.00%; Large-Cap Blend Portfolio 1.00%; Large-Cap
Value Portfolio 1.00%; Value Portfolio 1.00%; Small-Cap Value Portfolio 1.00%;
and International Equity Portfolio 1.00%.
 
The Administrator.  The Fund has entered into a Service Agreement under the
terms of which SunAmerica Fund Services, Inc. ('SAFS'), an indirect wholly owned
subsidiary of SunAmerica Inc., assists the transfer agent in providing
shareholder services. Pursuant to the Service Agreement, as compensation for
services rendered, SAFS receives a fee from the Fund, calculated and payable
monthly, at an annual rate of 0.22% of average daily net assets (in addition to
out-of-pocket charges reimbursed by the Fund). See the Statement of Additional
Information for further information.

PURCHASE OF SHARES
- --------------------------------------------------------------------------------
 
General.  Shares of each of the Portfolios are sold at the respective net asset
value next calculated after receipt of a purchase order, plus a sales charge,
which, at the election of the investor, may be imposed either (i) at the time of
purchase (Class A shares), or (ii) on a deferred basis (Class B and Class C
shares and certain Class A shares).
 
The minimum initial investment in each Portfolio is $500 and the minimum
subsequent investment is $100. However, for (i) wrap or certain other advisory
accounts for the benefit of clients of broker-dealers, financial institutions,
registered investment advisers or financial planners adhering to certain
standards established by the Distributor, and (ii) Individual Retirement
Accounts ('IRAs'), Keogh Plan accounts and accounts for other qualified plans,
the minimum initial investment is $250 and the minimum subsequent investment is
$25. The decision as to which class is most beneficial to an investor depends on
the amount and intended length of the investment. Investors should consult their
investment adviser for help in determining which class of shares is most
appropriate for them. Generally, investors making large investments, qualifying
for a reduced initial sales charge, might consider Class A shares because there
is a lower distribution fee than Class B and Class C shares. Shareholders who
purchase $1,000,000 or more of shares of the Portfolios should purchase only
Class A shares. Investors making small investments might consider Class B or
Class C shares because 100% of the purchase price is invested immediately.
Investors should consider the CDSC period and any conversion rights in the
context of their investment time frame. For example, while Class C shares have a
shorter CDSC period than Class B shares, Class C shares do not have a conversion
feature and, therefore, are subject to an ongoing distribution fee. Accordingly,
Class B shares may be more appropriate than Class C shares for investors with a
longer term investment time frame. Dealers may receive different levels of
compensation depending on which class of shares they sell.
 
Upon making an investment in shares of a Portfolio, an open account will be
established under which shares of the applicable Portfolio and additional shares
acquired through reinvestment of dividends and distributions will be held for
each shareholder's account by State Street Bank and Trust Company ('State
Street') and its affiliate, National Financial Data Services ('NFDS')
(collectively, the 'Transfer Agent'). Shareholders will not be issued
certificates for their shares unless they specifically so request in writing,
but no certificate is issued for fractional shares. Shareholders receive regular
statements from the Transfer Agent that report each transaction affecting their
accounts. Further information may be obtained by calling Shareholder/Dealer
Services at (800) 858-8850.
 
Class A Shares. Class A shares are offered at net asset value plus an initial
sales charge, which varies with the size of the purchase as follows:

No sales charge is payable at the time of purchase on investments of $1 million
or more. In addition, subject to the conditions listed below, shares may be
purchased at net asset value, without payment of a sales charge, by employee
benefit plans qualified under Sections 401 or 457 of the Code, or employee
benefit plans created pursuant to Section 403(b) of the Code and sponsored by
nonprofit organizations defined under Section 501(c)(3) of the Code
(collectively, 'Plans'). A Plan will qualify for purchases at net asset value
provided that (a) the initial amount invested in one or more of the Portfolios
(or in combination with the shares of other funds in the SunAmerica Mutual
Funds, which consist of the SunAmerica Equity Funds, SunAmerica Income Funds and
SunAmerica Money Market Funds) is at least $1,000,000, (b) the sponsor signs a
$1,000,000 Letter of Intent, (c) such shares are purchased by an
employer-sponsored plan with at least 100 eligible employees, or (d) the
purchases are by trustees or other fiduciaries for certain employer-sponsored
plans, the trustee, fiduciary or administrator for which has an agreement with
the Distributor with respect to such purchases and all such transactions for the
plan are executed through a single omnibus

account. Nevertheless, the Distributor will pay a commission to any dealer who
initiates or is responsible for such an investment, in the amount of 1.00% of
the amount invested. Redemptions of such shares within the twelve months
following their purchase will be subject to a CDSC at the rate of 1.00% of the
lesser of the net asset value of the shares being redeemed (exclusive of
reinvested dividends and distributions) or the total cost of such shares. This
CDSC is paid to the Distributor. Redemptions of such shares held longer than
twelve months would not be subject to a CDSC. However, one-half of the
commission paid with respect to such a purchase is subject to forfeiture by the
dealer in the event the redemption occurs during the second year from the date
of purchase. In determining whether a deferred sales charge is payable, it is
assumed that shares purchased with reinvested dividends and distributions and
then other shares held the longest are redeemed first.
 
To the extent that sales are made for personal investment purposes, the sales
charge is waived as to Class A shares purchased by current or retired officers,
directors, and other full-time employees of SunAmerica Inc. and its affiliates,
as well as members of the selling group and family members of the foregoing. In
addition, the sales charge is waived with respect to shares purchased by wrap or
certain other advisory accounts for the benefit of clients of broker-dealers,
financial institutions, registered investment advisers or financial planners
adhering to certain standards established by the Distributor. Shares purchased
under this waiver are subject to certain limitations described in the Statement
of Additional Information. Complete details concerning how an investor may
purchase shares at reduced sales charges may be obtained by contacting
Shareholder/Dealer Services at (800) 858-8850.
 
There are certain special purchase plans for Class A shares which can reduce the
amount of the initial sales charge to investors in the Portfolios. For more
information about 'Rights of Accumulation,' the 'Letter of Intent,' 'Combined
Purchase Privilege' and 'Reduced Sales Charges for Group Purchases,' see the
Statement of Additional Information.
 
Class B Shares.  Class B shares are offered at net asset value. Certain
redemptions of Class B shares within the first six years of the date of purchase
are subject to a CDSC. The charge is assessed on an amount equal to the lesser
of the then-current market value or the purchase price of the shares being
redeemed. No charge is assessed on shares derived from reinvestment of dividends
or capital gains distributions. In determining whether the CDSC is applicable to
a redemption, the calculation is determined in the manner that results in the
lowest possible rate being charged. Therefore, it is assumed that the redemption
is first of any shares of a class other than Class B that are not themselves
subject to a CDSC, second of any shares in the shareholder's Portfolio account
that are not subject to a CDSC (i.e., shares representing reinvested dividends
and distributions), third of Class B shares held for more than six years and
fourth of such shares held the longest during the six-year period. The CDSC will
not be applied to dollar amounts representing an increase in the net asset value
of the shares being redeemed since the time of purchase of such redeemed shares.
The amount of the CDSC, if any, will vary depending on the number of years from
the time of payment for the purchase of Class B shares until the time of
redemption of such shares. Solely for purposes of determining the number of
years from the time of any payment for the purchase of shares, all payments
during a month are aggregated and deemed to have been made on the first day of
the month. The following table sets forth the rates of the CDSC.

Conversion Feature--Class B Shares. Class B shares (including a pro rata portion
of the Class B shares purchased through the reinvestment of dividends and
distributions) will convert automatically to Class A shares on the first
business day of the month following the seventh anniversary of the issuance of
such Class B shares. Subsequent to the conversion of a Class B share to a Class
A share, such shares will no longer be subject to the higher distribution fee of
Class B shares. Such conversion will be on the basis of the relative net asset
values of Class B shares and Class A shares, without the imposition of any sales
load, fee or charge.
 
Class C Shares.  Class C shares are offered at net asset value. Certain
redemptions of Class C shares within the first year of the date of purchase are
subject to a CDSC of 1%. The method for calculating

any such CDSC will be the same method used for calculating the CDSC for Class B
shares. See 'Class B Shares' above.
 
Waiver of CDSC.  The CDSC applicable to Class B and Class C shares will be
waived, subject to certain conditions, in connection with redemptions that are
(a) requested within one year of the death of the shareholder of an individual
account or of a joint tenant where the surviving joint tenant is the deceased's
spouse; (b) requested within one year after the shareholder of an individual
account or a joint tenant on a spousal joint account becomes disabled; or the
initial determination of disability of a shareholder; (c) taxable distributions
or loans to participants made by qualified retirement plans or retirement
accounts (not including rollovers) for which SunAmerica serves as fiduciary
(e.g., prepares all necessary tax reporting documents); provided that, in the
case of a taxable distribution, the plan participant or account holder has
attained the age of 59 1/2 at the time the redemption is made; and (d) made
pursuant to a Systematic Withdrawal Plan, up to a maximum amount of 12% per year
from a shareholder account based on the value of the account at the time the
Plan is established, provided, however, that all dividends and capital gains
distributions are reinvested in Portfolio shares. See the Statement of
Additional Information for further information concerning conditions with
respect to (a) and (b) above. For information on the waiver of the CDSC contact
Shareholder/Dealer services at (800) 858-8850.
 
Other CDSC Information.  For Federal income tax purposes, the amount of the CDSC
will reduce the amount realized on the redemption of shares, concomitantly
reducing gain or increasing loss. For information on the imposition of the CDSC,
contact Shareholder/Dealer Services at (800) 858-8850.
 
Asset Protection Plan (Optional).  Anchor National Life Insurance Company (the
'Life Company'), an affiliate of SunAmerica and the Distributor, offers an Asset
Protection Plan to certain investors in the Portfolio. The benefits of this
optional term life insurance (payable on the death of the insured) will relate
to the amounts paid to purchase Portfolio shares and to the value of the
Portfolio shares held for the benefit of the insured persons. However, to the
extent such purchased shares are redeemed prior to death, coverage with respect
to such shares will terminate.
 
Purchasers of the Asset Protection Plan are required to authorize periodic
redemptions of Portfolio shares to pay the premiums for such coverage. Such
redemptions will not be subject to CDSCs, but will have the same tax
consequences as any other Fund redemptions.
 
The Asset Protection Plan will be available to eligible persons who enroll for
the coverage within a limited time period after shares in the Portfolio are
initially purchased or transferred. In addition, coverage cannot be made
available unless the Life Company knows for whose benefit shares are purchased.
For instance, coverage cannot be made available for shares registered in the
name of your broker unless the broker provides the Life Company with information
regarding the beneficial owners of such shares. In addition, coverage is
available only to shares purchased on behalf of natural persons under the age of
75 years; coverage is not available with respect to shares purchased for a
retirement account. Other restrictions on the coverage apply. This coverage may
not be available in all states and may be subject to additional restrictions or
limitations. Purchasers of shares should also make themselves familiar with the
impact on the Asset Protection Plan coverage of purchasing additional shares,
reinvestment of dividends and capital gains distributions and redemptions.
 
Please call (800) 858-8850 for more information, including the cost of the Asset
Protection Plan option.
 
Additional Purchase Information.  All purchases are confirmed to each
shareholder. The Fund reserves the right to reject any purchase order and may at

Shares of the Portfolios may be purchased through the Distributor or SAFS, by
check or federal funds wire and through a dollar cost averaging program. Checks
should be made payable to the specific Portfolio of the Fund. If the payment is

retirement plan accounts, both initial and subsequent purchases should be mailed
to SunAmerica Fund Services, Inc., Mutual Fund Operations, The SunAmerica
Center, 733 Third Avenue, New York, New York 10017-3204. SAFS reserves the right
to reject any check made payable other than in the manner indicated above. Under
certain circumstances, the Fund will accept a multi-party check (e.g., a check
made payable to the shareholder by another party and then endorsed by the
shareholder to the Fund in payment for the purchase of shares); however, the
processing of such a check may be subject to a delay. The Fund does not verify
the authenticity of the endorsement of such multi-party check, and acceptance of
the check by the Fund should not be considered verification thereof. Neither the
Fund nor its affiliates will be held liable for any losses incurred as a result
of a fraudulent endorsement. Shares will be priced at the net asset value next
determined after the order is placed with the Distributor or SAFS. See
'Additional Information Regarding Purchase of Shares' in the Statement of
Additional Information for more information regarding these services and the
procedures involved and when orders are deemed to be placed.

Shares of any Portfolio may be redeemed at any time at their net asset value
next determined, less any applicable CDSC, after receipt by the Fund of a
redemption request in proper form. Any capital gain or loss realized by a
shareholder upon any redemption of shares will be recognized for federal income
tax purposes, subject to certain loss deferral rules. See 'Dividends,
Distributions and Taxes.'
 
General.  Normally payment is made by check mailed on the next business day for
shares redeemed, but in any event, payment is made by check mailed within seven
days after receipt by the Transfer Agent of share certificates or of a
redemption request, or both, in proper form. Under unusual circumstances, the
Portfolio may suspend repurchases or postpone payment for up to seven days or
longer, as permitted by the federal securities laws.
 
Regular Redemption.  Shareholders may redeem their shares by sending a written
request to SAFS, Mutual Fund Operations, The SunAmerica Center, 733 Third
Avenue, New York, NY 10017-3204. Requests for redemption of shares with a value
of less than $100,000 will be made by check made payable to the shareholders(s)
and mailed to the address of record. All written requests for redemption of
shares with a value of $100,000 or more, or those mailed to an address other
than the address of record, must be endorsed by the shareholder(s) with
signature(s) guaranteed by an 'eligible guarantor institution' which includes:
banks, brokers, dealers, credit unions, securities and exchange associations,
clearing agencies and savings associations. Guarantees must be signed by an
authorized signatory of the eligible guarantor and the words 'Signature
Guaranteed' must appear with the signature. Signature guarantees by notaries
will not be accepted. SAFS may request further documentation from corporations,
executors, administrators, trustees or guardians.
 
Repurchase Through The Distributor.  The Distributor is authorized, as agent for
the Portfolios, to offer to repurchase shares which are presented by telephone
to the Distributor by investment dealers. Orders received by dealers must be at
least $500. The repurchase price is the net asset value per share of the
applicable class of shares of a Portfolio next-determined after the repurchase
order is received, less any applicable CDSC. Repurchase orders received by the
Distributor after the Fund's close of business, will be priced based on the next
business day's close. Dealers may charge for their services in connection with
the repurchase, but neither the

<PAGE>

58

STYLE SELECT SERIES(Registered)

Portfolios nor the Distributor imposes any such service charge. The offer to
repurchase may be suspended at any time, as described below.
 
Telephone Redemption.  The Fund accepts telephone requests for redemption of
shares with a value of less than $100,000. The proceeds of a telephone
redemption may be sent by check payable to the shareholder(s) and mailed to the
address of record by wire to the shareholder's bank account as set forth in the
New Account Application Form or in a subsequent written authorization.
Shareholders utilizing the redemption through the electronic funds transfer
method will incur a $15.00 transaction fee. The Fund will employ reasonable
procedures to confirm that instructions communicated by telephone are genuine.
Failure to do so may result in liability to the Fund for losses incurred due to
unauthorized or fraudulent telephone instructions. Such procedures include, but
are not limited to, requiring some form of personal identification prior to
acting upon instructions received by telephone and/or tape recording of
telephone instructions.
 
A shareholder making a telephone redemption should call Shareholder/Dealer
Services at (800) 858-8850, and state (i) the name of the shareholder(s)
appearing on the Fund's records, (ii) his or her account number with the Fund,
(iii) the name of the Portfolio, (iv) the amount to be redeemed, and (v) the
name of the person(s) requesting the redemption. The Fund reserves the right to
terminate or modify the telephone redemption service at any time.
 
Systematic Withdrawal Plan.  Shareholders who have invested at least $5,000 in
any of the Portfolios may provide for the periodic payment from the account
pursuant to the Systematic Withdrawal Plan. At the shareholder's election, such
payment may be made directly to the shareholder or to a third party on a
monthly, quarterly, semi-annual or annual basis. The minimum periodic payment is
$50. Maintenance of a withdrawal plan concurrently with purchases of additional
shares may be disadvantageous to a shareholder because of the sales charge
applicable to such purchases. Shareholders who have been issued share
certificates will not be eligible to participate in the Systematic Withdrawal
Plan and will have to comply with certain additional procedures in order to
redeem shares. Further information may be obtained by calling Shareholder/
Dealer Services at (800) 858-8850.
 
Other Redemption Information.  At various times, a Portfolio may be requested to
redeem shares for which it has not yet received good payment. A Portfolio may
delay or cause to be delayed the mailing of a redemption check until such time
as good payment (e.g., cash or certified check drawn on a United States bank)
has been collected for the purchase of such shares, which will not exceed 15
days.
 
Because of the high cost of maintaining smaller shareholder accounts, the
Portfolio may redeem, on at least 60 days' written notice and without
shareholder consent, any account that has a net asset value of less than $500
($250 for retirement plan accounts), as of the close of business on the day
preceding such notice, unless such shareholder increases the account balance to
at least $500 during such 60-day period. In the alternative, the applicable
Portfolio may impose a $2.00 monthly charge on accounts below the minimum
account size.
 
If a shareholder redeems shares of any class of a Portfolio and then within one
year from the date of redemption decides the shares should not have been
redeemed, the shareholder may use all or any part of the redemption proceeds to
reinstate, free of sales charges (Class A shares) and with the crediting of any
CDSC paid with respect to such reinstated shares at the time of redemption
(Class B and Class C shares), all or any part of the redemption proceeds in
shares of the Portfolio at the then-current net asset value. Reinstatement may
affect the tax status of the prior redemption.
 
EXCHANGE PRIVILEGE
- --------------------------------------------------------------------------------
 
General.  Shareholders in any of the Portfolios may exchange their shares for
the same class of shares of any other Portfolio or other SunAmerica Fund that
offers such class at the respective net asset value per share. Additionally,
Class C shareholders of a Portfolio may exchange their shares for Class II
shares of another fund in the SunAmerica Family of Mutual Funds. Before making
an exchange, a shareholder should obtain and review the prospectus of the fund
whose shares are being acquired. All exchanges are subject to applicable minimum
initial investment requirements and can only be effected if the shares

<PAGE>
                                                                              59

                                                STYLE SELECT SERIES(Registered)

to be acquired are qualified for sale in the state in which the shareholder
resides. Exchanges of shares generally will constitute a taxable transaction
except for IRAs, Keogh Plans and other qualified or tax-exempt accounts. The
exchange privilege may be terminated or modified upon 60 days' written notice.
Further information about the exchange privilege may be obtained by calling
Shareholder/ Dealer Services at (800) 858-8850.
 
If a shareholder acquires Class A shares through an exchange from another fund
in the SunAmerica Family of Mutual Funds where the original purchase of such
fund's Class A shares was not subject to an initial sales charge because the
purchase was in excess of $1 million, such shareholder will remain subject to
the 1% CDSC, if any, applicable to such redemptions. In such event, the period
for which the original shares were held prior to the exchange will be 'tacked'
with the holding period of the shares acquired in the exchange for purposes of
determining whether the 1% CDSC is applicable upon a redemption of any of such
shares.
 
A shareholder who acquires Class B or Class C shares through an exchange from
another fund in the SunAmerica Family of Mutual Funds will retain liability for
any CDSC outstanding on the date of the exchange. In such event, the period for
which the original shares were held prior to the exchange will be 'tacked' with
the holding period of the shares acquired in the exchange for purposes of
determining what, if any, CDSC is applicable upon a redemption of any of such
shares and of determining the timing of conversion of Class B shares to Class A.
 
Restrictions on Exchanges.  Because excessive trading (including short-term
'market timing' trading) can hurt a Portfolio's performance, each Portfolio may
refuse any exchange sell order (1) if it appears to be a market timing
transaction involving a significant portion of a Portfolio's assets or (2) from
any shareholder account if previous use of the exchange privilege is considered
excessive. Accounts under common ownership or control, including, but not
limited to, those with the same taxpayer identification number and those
administered so as to redeem or purchase shares based upon certain predetermined
market indications, will be considered one account for this purpose.
 
In addition, a Portfolio reserves the right to refuse any exchange purchase
order if, in the judgment of SunAmerica, the Portfolio would be unable to invest
effectively in accordance with its investment objective and policies, or would
otherwise potentially be adversely affected. A shareholder's purchase exchange
may be restricted or refused if the Portfolio receives or anticipates
simultaneous orders affecting significant portions of the Portfolio's assets. In
particular, a pattern of exchanges that coincide with a 'market timing' strategy
may be disruptive to the Portfolio and may therefore be refused.
 
Finally, as indicated under 'Purchase of Shares,' the Fund and Distributor
reserve the right to refuse any order for the purchase of shares.
 
PORTFOLIO TRANSACTIONS, BROKERAGE AND TURNOVER
- --------------------------------------------------------------------------------
 
The Advisers are responsible for decisions to buy and sell securities for the
Portfolios, selection of broker-dealers and negotiation of commission rates for
their respective portion of the relevant Portfolio. In the over-the-counter
market, securities are generally traded on a 'net' basis with dealers acting as
principal for their own accounts without a stated commission (although the price
of the security usually includes a profit to the dealer). In underwritten
offerings, securities are purchased at a fixed price which includes an
underwriter's concession or discount. On occasion, certain money market
securities may be purchased directly from an issuer, in which case no
commissions or discounts are paid.
 
As a general matter, the Advisers select broker-dealers which, in their best
judgment, provide prompt and reliable execution at favorable security prices and
reasonable commission rates. The Advisers may select broker-dealers which
provide them with research services and may cause a Portfolio to pay such
broker-dealers commissions which exceed those which other broker-dealers may
have charged, if in the Adviser's view the commissions are reasonable in
relation to the value of the brokerage and/or research services provided by the
broker-dealer. Brokerage arrangements may take into account the distribution of
Fund shares by broker-dealers, subject to best price and execution. In addition,
brokerage may be allocated to brokers that pay (or cause

<PAGE>

60

STYLE SELECT SERIES(Registered)

to be paid) expenses of the respective Portfolio, subject to best price and
execution. An Adviser may effect portfolio transactions through an affiliated
broker-dealer, acting as agent and not as principal, in accordance with Rule
17e-1 under the 1940 Act and other applicable securities laws.
 
Each Portfolio has no limitation regarding its policy with respect to portfolio
turnover. The portfolio turnover rate is calculated by dividing the lesser of
sales or purchases of portfolio securities, excluding short-term securities, by
the average monthly value of the Portfolio's long-term portfolio securities.
Under certain market conditions, the investment policies of the Portfolios may
result in high portfolio turnover. Because each of the Advisers to each
Portfolio manages its portion of the Portfolio's assets independently, it is
possible that the same security may be purchased and sold on the same day by two
or more Advisers to the same Portfolio, resulting in higher brokerage
commissions for the Portfolio. Notwithstanding the foregoing, however, the
portfolio turnover rates for any Portfolio are not expected to exceed 200%. High
portfolio turnover involves correspondingly greater brokerage commissions and
other transaction costs which will be borne directly by the Portfolio. In
addition, high portfolio turnover may result in increased short-term capital
gains, which, when distributed to shareholders, are currently treated as
ordinary income.
 
DETERMINATION OF NET ASSET VALUE
- --------------------------------------------------------------------------------
 
Each Portfolio is open for business on any day the NYSE is open for regular
trading. Shares are valued each day as of the close of regular trading on the
NYSE (generally, 4:00 p.m., Eastern time). Each Portfolio calculates the net
asset value per share of each class separately by dividing the total value of
each class's net assets by the number of shares outstanding of each class.
Investments for which market quotations are readily available are valued at
market at their closing price. All other securities and assets are valued at
fair value following procedures approved by the Directors. For a complete
description of the procedures involved in valuing various Fund assets, see the
Statement of Additional Information.
 
PERFORMANCE DATA
- --------------------------------------------------------------------------------
 
Each Portfolio may advertise performance data that reflect its total investment
return. A brief summary of the computations is provided below and a detailed
discussion is in the Statement of Additional Information. Total return is based
on historical earnings and is not intended to indicate future performance.
 
Total return performance data may be advertised by each Portfolio. The average
annual total return may be calculated for one-, five- and ten-year periods
or for the lesser period since inception. These
performance data represent the average annual percentage changes of a
hypothetical $1,000 investment and assumes the reinvestment of all dividends and
distributions and includes sales charges and recurring fees that are charged to
shareholder accounts. A Portfolio's advertisements may also reflect total return
performance data calculated by means of cumulative, aggregate, average, year-to-
date, or other total return figures. Further, the Portfolio may advertise total
return performance for periods of time in addition to those noted above.
 
Although expenses for Class B and Class C shares may be higher than those for
Class A shares, the performance of Class B and Class C shares may be higher than
the performance of Class A shares after giving effect to the impact of the sales
charges and 12b-1 fees applicable to each class of shares.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
Dividends and Distributions.  For each Portfolio other than the Large-Cap Blend
Portfolio, dividends from net investment income, if any, are to be paid at least
annually. For the Large-Cap Blend Portfolio, dividends from net investment
income, if any, are to be paid quarterly. Dividends and distributions generally
are taxable in the year in which they are paid, except any dividends paid in
January which were declared in the previous calendar quarter will be treated as
paid in December of the previous year.

<PAGE>
                                                                              61

                                                STYLE SELECT SERIES(Registered)

Dividends and distributions are to be paid in additional shares based on the
next determined net asset value, unless the shareholder elects in writing, not
less than five business days prior to the payment date, to receive amounts in
excess of $10 in cash.
 
If a shareholder has elected to receive dividends and/or capital gain
distributions in cash, and the postal or other delivery service is unable to
deliver checks to the shareholder's address of record, no interest will accrue
on amounts represented by uncashed dividend or distribution checks.
 
In addition to having the dividends and distributions of a Portfolio reinvested
in shares of such Portfolio, a shareholder may, if he or she so elects on the
New Account Application, have dividends and distributions invested in the same
class of shares of any other SunAmerica Mutual Fund or any other Portfolio of
the Fund at the then-current net asset value of such fund(s).
 
The excess of net realized capital gains from the sale of assets held for more
than 12 months over net capital losses ('net capital gains'), if any, with
respect to each Portfolio, will be distributed to the shareholders at least
annually. Each Portfolio's policy is to offset any prior year capital loss carry
forward against any realized capital gains, and accordingly, no distribution of
capital gains will be made until gains have been realized in excess of any such
loss carry forward.
 
Taxes.  Each Portfolio intends to qualify and elect to be taxed as a regulated
investment company under the Code. While so qualified, the Fund and each of the
Portfolios will not be subject to U.S. Federal income tax on the portion of its
investment company taxable income and net capital gains distributed to its
shareholders.
 
Dividends of net investment income and distributions of any net realized
short-term capital gain ('ordinary income dividends'), whether paid in cash or
reinvested in shares of the Portfolios, are taxable to shareholders as ordinary
income. Distributions made from the Fund's net capital gains (including gains
from certain transactions in futures and options) are taxable to shareholders as
capital gains, regardless of the length of time the shareholder has owned Fund
shares. To the extent a Portfolio's income is derived from certain dividends
received from domestic corporations, a portion of the dividends paid to
corporate shareholders of such Portfolios will be eligible for the 70%
dividends-received deduction. It generally is not anticipated that dividends
paid by the International Equity Portfolio will qualify for the dividends-
received deduction.
 
Ordinary income dividends paid by the Fund to shareholders who are non-resident
aliens or foreign entities generally will be subject to a 30% United States
withholding tax under existing provisions of the Code applicable to foreign
individuals and entities unless a reduced rate of withholding or a withholding
exemption is provided under applicable treaty law. Nonresident shareholders are
urged to consult their own tax advisers concerning the applicability of the
United States withholding tax.
 
Income and capital gains received by each Portfolio with respect to foreign
investments may give rise to withholding and other taxes imposed by foreign
countries. Tax conventions between certain countries and the U.S. may reduce or
eliminate such taxes. Shareholders may be able to claim U.S. foreign tax credits
with respect to such taxes, subject to certain provisions and limitations
contained in the Code. If more than 50% in value of the Portfolio's total assets
at the close of its taxable year consists of securities of foreign corporations,
the Portfolio will be eligible and may choose to file an election with the
Internal Revenue Service pursuant to which shareholders of the Portfolio may
include their proportionate share of such withholding taxes in their U.S. income
tax returns as gross income, treat such proportionate share as taxes paid by
them, and deduct such proportionate share in computing their taxable incomes or,
alternatively, subject to certain limitations, holding period requirements and
other provisions, use them as foreign tax credits against their U.S. income
taxes. No deductions for foreign taxes, however, may be claimed by non-corporate
shareholders who do not itemize deductions. Of course, certain retirement
accounts which are not subject to tax cannot claim foreign tax credits on
investments in foreign securities held in the Fund. A shareholder that is a
nonresident alien individual or a foreign corporation may be subject to U.S.
withholding tax on the income resulting from the Portfolio's election described
in this paragraph but may not be able to claim a credit or deduction against
such U.S. tax for the foreign taxes treated as having been paid by such
shareholder. The Portfolio will report annually to its shareholders the amount
per share of such withholding taxes. It is not anticipated that the Portfolios,
other than the International Equity Portfolio, will qualify to elect to pass
foreign taxes through to their shareholders.
 
No gain or loss will be recognized by Class B shareholders on the conversion of
their Class B shares into Class A shares. A shareholder's basis in the Class A
shares acquired will be the same as such shareholder's basis in the Class B
shares converted,
<PAGE>

62

STYLE SELECT SERIES(Registered)

and the holding period of the acquired Class A shares will include the holding
period for the converted Class B shares.
 
A shareholder who holds shares as a capital asset (i.e., generally, for
investment) generally will recognize a capital gain or loss upon the sale or
exchange of such shares. In the case of an individual, any such capital gain
will be treated as short-term capital gain if the shares were held for not more
than 12 months, capital gain taxable at the maximum rate of 28% if such shares
were held for more than 12, but not more than 18 months, and capital gain
taxable at the maximum rate of 20% if such shares were held for more than 18
months. In the case of a corporation, any such capital gain will be treated as
long-tem capital gain, taxable at the same rates as ordinary income, if such
shares were held for more than 12 months. Any such capital loss will be a long-
term capital loss if such shares were held for more than one year. However, any
loss realized by a shareholder who held shares for six months or less will be
treated as a long-term capital loss to the extent of any distributions of net
capital gains received by the shareholder with respect to such shares.
 
If a shareholder exercises the exchange privilege within 90 days of acquiring
such shares, then the loss the shareholder can recognize on the exchange will be
reduced (or the gain increased) to the extent the sales charge paid to the Fund
reduces any charges the shareholder would have owed upon the purchase of the new
shares in the absence of the exchange privilege. Instead, such sales charge will
be treated as an amount paid for the new shares. See 'Exchange Privilege.'
 
A loss realized on a sale or exchange of shares of the Fund will be disallowed
if other Fund shares are acquired (whether through the automatic reinvestment of
dividends or otherwise) within a 61-day period beginning 30 days before and
ending 30 days after the date that the shares are disposed of. In such a case,
the basis of the shares acquired will be adjusted to reflect the disallowed
loss.
 
Under certain provisions of the Code, some shareholders may be subject to a 31%
withholding tax on ordinary income dividends, capital gains distributions and
redemption payments ('backup withholding'). Generally, shareholders subject to
backup withholding will be those for whom no certified taxpayer identification
number is on file with the Fund or who, to the Fund's knowledge, have furnished
an incorrect number. When establishing an account, an investor must certify
under penalty of perjury that such number is correct and that the investor is
not otherwise subject to backup withholding.
 
Statements as to the tax status of distributions to shareholders of the Fund
will be mailed annually. Shareholders are urged to consult their own tax
advisers regarding specific questions as to federal, state or local taxes.
Foreign shareholders are also urged to consult their own tax advisers regarding
the foreign tax consequences of ownership of interests in a Portfolio. See
'Dividends, Distributions and Taxes' in the Statement of Additional Information.
 
GENERAL INFORMATION
- --------------------------------------------------------------------------------
 
Reports to Shareholders.  The Fund sends to its shareholders audited annual and
unaudited semi-annual reports for the Portfolios. The financial statements
appearing in annual reports are audited by independent accountants. In addition,
the Transfer Agent sends to each shareholder having an account directly with the
Fund a statement confirming transactions in the account.
 
Organization.  The Fund, a corporation organized under the laws of the state of
Maryland on July 3, 1996, is an open-end management investment company, commonly
referred to as a mutual fund. The total number of shares which the Fund has
authority to issue is one billion (1,000,000,000) shares of common stock (par
value $0.0001 per share), amounting in aggregate par value to one hundred
thousand dollars ($100,000.00). All of such shares of common stock are
classified into nine separate Portfolios known as the Large-Cap Growth
Portfolio, the Mid-Cap Growth Portfolio, the Aggressive Growth Portfolio, the
Large-Cap Blend Portfolio, the Large-Cap Value Portfolio, the Value Portfolio,
the Small-Cap Value Portfolio, the International Equity Portfolio and the Focus
Portfolio. Except for the Focus Portfolio, all of the shares of each such
Portfolio are initially classified into four classes: Class A, Class B, Class C
or Class Z. Each such Portfolio initially consists of twenty-five million
(25,000,000) shares of each class. Only Class A, Class B and Class C shares are
currently being offered to the public. The Focus Portfolio is offered through a
separate prospectus which can be obtained by contacting Shareholder/Dealer
Services at (800) 858-8850.
 
The Fund does not hold annual shareholder meetings. The Directors are required
to call a meeting of shareholders for the purpose of voting upon the

<PAGE>

                                                                              63

                                                STYLE SELECT SERIES(Registered)

question of removal of any Director when so requested in writing by the
shareholders of record holding at least 10% of the Fund's outstanding shares.
Each share of each Portfolio has equal voting rights on each matter pertaining
to that Portfolio or matters to be voted upon by the Fund. Each share of each
Portfolio is entitled to participate equally with the other shares of that
Portfolio in dividends and other distributions and the proceeds of any
liquidation, except that, due to the differing expenses borne by the classes,
such dividends and proceeds are likely to be lower for Class B and Class C
shares than for Class A shares. See the Statement of Additional Information for
more information with respect to the distinctions among classes.
 
Independent Accountants and Legal Counsel.  Price Waterhouse LLP has been
selected as independent accountants for the Fund. The firm of Shereff, Friedman,
Hoffman & Goodman, LLP has been selected as legal counsel for the Fund.
 
Year 2000 Readiness.  Many services provided to the Fund and the shareholders by
SunAmerica, the Advisers, the Distributor and the Administrator rely on the
smooth functioning of their computer and computer-based systems as well as those
of their outside service providers. Many computer and computer-based systems
cannot distinguish the year 2000 from the year 1900 because of the way the
systems encode and calculate dates. This year 2000 issue could potentially have
an adverse impact on the handling of security trades, the payment of interest
and dividends, pricing and account services. SunAmerica, the Advisers, the
Distributor and the Administrator recognize the importance of the year 2000
issue and are taking the appropriate steps necessary in preparation of the year
2000. SunAmerica, the Advisers, the Distributor and the Administrator fully
anticipate that their systems and those of their outside service providers will
be adapted in time for the year 2000, and to further this goal have coordinated
a plan to repair, adapt or replace systems that are not year 2000 compliant, and
have obtained similar representations from their outside service providers.
SunAmerica, the Advisers, the Distributor and the Administrator expect to
significantly complete their plan by the end of the 1998 calendar year and
perform appropriate systems testing in the 1999 calendar year.
