ended December 31, 1996 which have been restated to reflect current expenses,
the modifications of certain voluntary waivers and credits allowed by the
custodian. The ranges show what the combined expenses would be assuming asset
allocation among the Funds that would result in the lowest combined expenses and
assuming asset allocation among the Funds that would result in the highest
combined expenses. See "Investment and Risk Considerations of the Portfolios"

HIGHLIGHTS
    
 
   
The Portfolios offer purchasers of the Sierra Asset Manager Contract the
opportunity to pursue an asset allocation strategy through participation in a
combination of Funds designed to accommodate different investment philosophies
and goals. Investors participating in the Portfolios bear the operating expenses
of the Portfolios (including investment advisory and administrative fees), as
well as the operating expenses of the Underlying Funds. Investors who do not
wish to participate in the Portfolios' asset allocation strategies, and who wish
to purchase an annuity contract under which they select the Funds in which to
participate, may consider purchasing the Sierra Advantage Contract issued by
AGL.
    
 
   
INVESTMENT OBJECTIVES AND POLICIES
    
 
   
The investment objectives and policies of the Portfolios are pursued through
investment in combinations of Funds of the Trust as set forth in "Investment and
Risk Considerations of the Portfolios." Futures contracts and options may also
be used under certain conditions to help in achieving a Portfolio's objective.
The investment objective of each Portfolio and the Global Money Fund and the
investment policies and restrictions that are specifically cited as fundamental
may not be changed without the approval of a majority of the outstanding shares
of that Portfolio or Underlying Fund, respectively. A complete list of
investment restrictions that identifies additional restrictions that cannot be
changed without the approval of a majority of an affected Portfolio's or
Underlying Fund's outstanding shares is contained in the SAI. There is no
assurance that a Portfolio or Underlying Fund will meet its stated objective.
    
 
   
The INCOME PORTFOLIO seeks long term total return through reinvestment of
current income consistent with preservation of capital, primarily through
participation in the domestic fixed income markets with limited participation in
international fixed income markets.
    
 
The VALUE PORTFOLIO seeks total return consisting of reinvestment of income with
some capital appreciation, primarily through investments in domestic and
international fixed income markets with limited participation in domestic and
international equity markets.
 
The BALANCED PORTFOLIO seeks total return consisting of a combination of
reinvestment income and capital appreciation, consistent with reasonable risk
through limited participation in domestic and international fixed income and
equity markets.
 
                                        4
<PAGE>   9
 
   
The GROWTH PORTFOLIO seeks to provide long-term capital appreciation through
participation in domestic and international equity markets, with limited
participation in domestic and international fixed income markets.
    
 
   
The CAPITAL GROWTH PORTFOLIO seeks to provide long-term capital appreciation
primarily through participation in domestic and international equity markets,
with limited participation in domestic and international fixed income markets.
    
 
   
The GLOBAL MONEY FUND seeks to maximize current income consistent with safety of
principal and maintenance of liquidity. It will pursue this objective by
investing in U.S. dollar denominated money market instruments of foreign and
U.S. issuers. It also seeks to maintain a stable net asset value of $1.00 per
share.
    
 
   
RISK FACTORS
    
 
   
Investing in the Portfolios involves certain additional expenses and tax results
that would not be present in a direct investment in the Underlying Funds. One or
more of the Underlying Funds used for investment by a Portfolio may experience
relatively large investments or redemptions due to reallocations or rebalancings
by the Portfolios, which could have a negative impact on that Fund's
performance. In addition, certain Underlying Funds in which the Portfolios
invest are permitted to invest a portion of their assets in foreign securities,
lower-rated bonds (commonly referred to as "junk bonds") and engage in various
other investment practices, some of which may be considered speculative. See
"Risk Factors of the Portfolios."
    
 
INVESTMENT ADVISORS
 
   
Subject to the authority of the Board of Trustees, Sierra Investment Services
Corporation ("Sierra Services" or the "Advisor" or the "Distributor") serves as
the investment advisor of the Portfolios and has overall management of the
investment strategies and policies of the Portfolios. Subject to the same
authority, Sierra Investment Advisors Corporation ("Sierra Advisors") serves as

investment strategies and policies of the Underlying Funds, including the Global
Money Fund. The Trust and Sierra Advisors has secured the services of
sub-advisors for each Fund, including the Global Money Fund, to make investment
decisions and place orders.
    
 
DISTRIBUTION
 
Sierra Services serves as the Trust's distributor and distributes the shares of
the Funds and the Portfolios to the separate accounts, which purchase and redeem
these shares at net asset value without sales or redemption charges.
 
ADMINISTRATION
 
   
Sierra Fund Administration Corporation ("Sierra Administration") serves as
Administrator to the Trust and has responsibility for the Trust's administrative
functions. Sierra Administration has engaged First Data Investor Services Group,
Inc. ("FDISG"), a wholly-owned subsidiary of First Data Corporation, as
sub-administrator. FDISG also serves as the Trust's Transfer Agent and Boston
Safe Deposit & Trust Company ("Boston Safe") serves as the Trust's custodian.

INVESTMENT AND RISK CONSIDERATIONS OF THE PORTFOLIOS
 
   
Each Portfolio typically allocates its assets, within predetermined percentage
ranges, among some or all of the Funds. Subject to Board approval, the Advisor
may alter these percentage ranges when it deems appropriate. The percentages
reflect the extent to which each Portfolio will invest in the particular market
segment represented by each Fund, and the varying degrees of potential
investment risk and reward represented by each Portfolio's investments in those
market segments and their corresponding Funds. The assets of each Portfolio will
be allocated among each of the Funds in accordance with its investment
objective, the Advisor's outlook for the economy and the financial markets and
the relative market valuations of the Funds. For purposes of complying with the
diversification requirements of Subchapter L, Section 817(h), of the Internal
Revenue Code and Treasury Regulation Section 1.817-5 (applicable to investments
of insurance company separate accounts), no more than 55% of a Portfolio's
assets will be represented by investments in any one Fund, no more than 70% of
the Portfolio's assets will be represented by investments in any two Funds, no
more than 80% of the Portfolio's assets will be represented by investments in
any three Funds and no more than 90% of the Portfolio's assets will be
represented by investments in any four Funds. The investments of the Funds will
also comply with those diversification requirements. Under current investment
policies of the Portfolios, the maximum percentage of the assets of a Portfolio
that may be invested in a Fund is less than 55% (see "Dividends, Distributions
and Taxes" below).
    
 
   
To meet liquidity needs or for temporary defensive purposes, each Portfolio may
invest its assets directly in cash, stock or bond index futures and options
thereon and the following short-term instruments: (i) short-term obligations of
the U.S. Government, its agencies, instrumentalities, authorities or political
subdivisions; (ii) other short-term debt securities rated A or higher by Moody's
Investor Services, Inc. ("Moody's") or Standard & Poor's Corporation ("S&P"), or
if unrated, of comparable quality in the opinion of the Portfolio's investment
advisor; (iii) commercial paper, including master notes; (iv) bank obligations,
including negotiable certificates of deposit, time deposits and bankers'
acceptances; and (v) repurchase agreements. At the time the Portfolio invests in
any commercial paper, bank obligations or repurchase agreements, the issuer must
have outstanding debt rated A or higher by Moody's or S&P; the issuer's parent
corporation, if any, must have outstanding commercial paper rated Prime-1 by
Moody's or A-1 by S&P; or, if no such ratings are available, the investment must
be of comparable quality in the opinion of Sierra Services. The investment
objective of each Portfolio is set forth below. Each Portfolio's investment
objective is a fundamental policy, and may not be changed without shareholder
approval. There can be no assurance that a Portfolio will achieve its stated
objective. For purposes of discussing Portfolio objectives, the "Fixed Income
Funds" include the Global Money Fund, Short Term High Quality Bond Fund, Short
Term Global Government Fund, U.S. Government Fund and Corporate Income Fund and
the "Equity Funds" include the Growth and Income Fund, Growth Fund, Emerging
Growth Fund and International Growth Fund.

CAPITAL GROWTH PORTFOLIO
 
   
The CAPITAL GROWTH PORTFOLIO seeks to provide long-term capital appreciation. In
general, relative to the other Portfolios, the Capital Growth Portfolio should
offer investors the potential for a higher level of capital growth while
subjecting investors to corresponding levels of principal risk. Subject to
meeting all applicable diversification requirements under the Internal Revenue
Code, the Portfolio may invest in the following Funds up to the percentage
limits set forth below:

Except for defensive periods or liquidity needs, the Capital Growth Portfolio
must invest at least 75% of its net assets available for investment in Equity
Funds.
 
GENERAL INVESTMENT POLICIES OF THE PORTFOLIOS
 
   
Each of the Portfolios will attempt to achieve its investment objective by
purchasing shares of the Funds within the percentage ranges for such Portfolio
set forth above. In addition to purchasing shares of the Funds, a Portfolio may
use futures contracts and options in order to remain effectively fully invested
in proportions consistent with the Advisor's current asset allocation strategy
for the Portfolio in an efficient and cost effective manner. Specifically, each
Portfolio may enter into futures contracts and options thereon provided that the
aggregate deposits required on these contracts do not exceed 5% of the
Portfolio's total assets. A Portfolio may also use futures contracts and options
for bona fide hedging transactions.
    
 
Futures contracts and options may also be used to reallocate the Portfolio's
assets among asset categories while minimizing transaction costs, to maintain
cash reserves while simulating full investment, to facilitate trading, to seek
higher investment returns, or to simulate full investment when a futures
contract is priced attractively or is otherwise considered more advantageous
than the underlying security or index. While futures contracts and options can
be used as leveraged instruments, the Portfolios will not use futures contracts
or options to leverage their portfolios, except as indicated above.
 
PORTFOLIO TURNOVER OF THE PORTFOLIOS
 
Each Portfolio's portfolio turnover rate (i.e., the rate at which the Portfolio
buys and sells shares of the Funds) for the Income, Value, Balanced and Growth
Portfolios is not expected to exceed 125% of the Portfolio's total assets. The
annual turnover rate for the Capital Growth Portfolio is not expected to exceed
150%. Asset reallocation decisions typically will occur only once every quarter.
However, if market conditions warrant, the Advisor may make more frequent
reallocation decisions, which will result in a higher portfolio turnover rate.
The Portfolios will purchase or sell shares of the Funds: (a) to accommodate
purchases and redemptions of each Portfolio's shares; (b) in response to market
or other economic conditions; and (c) to maintain or modify the allocation of
each Portfolio's assets among the Funds within the percentage limits described
above or as altered by the Advisor from time to time. It is important to note,
however, that the portfolio turnover rate of certain of the Funds (i.e., the
rate at which the Funds buy and sell securities) may exceed 100%. Such a
turnover rate may result in higher transaction costs and may result in
additional tax consequences for shareholders (including the Portfolios).
 
RISK FACTORS OF THE PORTFOLIOS
 
Like any investment in an investment company, an investment in the Portfolios
involves risk. Prospective investors in the Portfolios should consider the
following factors:
 
     -  Investing in the Funds through the Portfolios involves certain
        additional expenses and tax results that would not be present in a
        direct investment in the Funds. See "Dividends, Distributions and Taxes"
        for additional information about tax implications of investing in the
        Portfolios.
 
     -  Under certain circumstances, a Fund may determine to make payment of a
        redemption request by a Portfolio wholly or partly by a distribution in
        kind of securities from its portfolio, instead of cash, in accordance
        with the rules of the SEC. In such cases, the Portfolios may hold
        securities distributed by a Fund until the Advisor determines that it is
        appropriate to dispose of such securities.
 
     -  Certain Funds may invest a portion of their assets in foreign
        securities; enter into forward currency transactions; lend their
        portfolio securities; enter into stock index, interest rate and currency
        futures contracts, and options on such contracts; enter into interest
        rate swaps or purchase or sell interest rate caps or floors; engage in
        other types of options transactions; make
 
                                       10
<PAGE>   15
 
   
        short sales; purchase zero coupon and payment-in-kind bonds; engage in
        repurchase or reverse repurchase agreements; purchase and sell
        "when-issued" securities and engage in "delayed-delivery" transactions;
        and engage in various other investment practices, some of which may be
        considered speculative. Further information about these investment
        policies and practices can be found under "APPENDIX -- SECURITIES AND
        INVESTMENT PRACTICES" in this Prospectus and in the Trust's Statement of
        Additional Information, and in the Prospectus(es) of each of the Funds.
    
 
   
     -  The Capital Growth Portfolio can invest as much as 50% of its total
        assets in the Growth Fund and as much as 50% of its total assets in the
        Emerging Growth Fund, each of which Funds may invest as much as 35% of
        its total assets in lower-rated bonds, commonly referred to as "junk
        bonds." As a result, this Portfolio will be subject to the risks
        associated with investing in such lower-rated bonds. See
        "APPENDIX -- SECURITIES AND INVESTMENT PRACTICES -- Lower-Rated
        Securities" for additional information about such risks.
    
 
   
     -  Certain Portfolios may invest as much as 50% of their total assets in
        the Growth Fund or Emerging Growth Fund, each of which may invest up to
        25% of its total assets in foreign equity securities and as much as 5%
        of its total assets in securities in developing or emerging markets
        countries (a country in the initial stages of its industrialization
        cycle). Certain Portfolios may invest as much as 50% of their total
        assets in the International Growth Fund, which invests primarily in
        foreign equity securities, and may invest as much as 30% of its total
        assets in securities in developing or emerging markets countries. These
        investments will subject such Portfolios to risks associated with
        investing in foreign securities. See "APPENDIX -- SECURITIES AND
        INVESTMENT PRACTICES -- Foreign Investments" for additional information
        about such risks.
    
 
     -  The officers and trustees of the Portfolios also serve as officers and
        trustees of the Funds. In addition, Sierra Services, the investment
        advisor and distributor of each Portfolio, and Sierra Advisors, the
        investment advisor of the Funds, are both wholly owned subsidiaries of
        Sierra Capital Management Corporation ("SCMC"). Also, the Advisor is the
        distributor of the shares of the Funds. Conflicts may arise as these
        companies seek to fulfill their fiduciary responsibilities to both the
        Portfolios and the Funds.
 
     -  From time to time, one or more of the Funds used for investment by a
        Portfolio may experience relatively large investments or redemptions due
        to reallocations or rebalancings by the Portfolios as recommended by the
        Advisor. These transactions will affect the Funds, since the Funds that
        experience redemptions as a result of reallocations or rebalancings may
        have to sell portfolio securities and Funds that receive additional cash
        will have to invest such cash. While it is impossible to predict the
        overall impact of these transactions over time, there could be adverse
        effects on portfolio management to the extent that the Funds may be
        required to sell securities or invest cash at times when they would not
        otherwise do so. These transactions could also have tax consequences if
        sales of securities resulted in gains and could also increase
        transaction costs. Sierra Advisors, representing the interests of the
        Funds, is committed to minimizing the impact of Portfolio transactions
        on the Funds; the Advisor, representing the interest of the shareholders
        of the Portfolios, is also committed to minimizing such impact on the
        Funds to the extent it is consistent with pursuing the investment
        objectives of the Portfolios. The Advisor and Sierra Advisors will
        nevertheless face conflicts in fulfilling their respective
        responsibilities because they are affiliates and employ some of the same
        investment professionals. The Advisor and Sierra Advisors will monitor
        the impact of Portfolio transactions on the Funds.

INVESTMENT LIMITATIONS OF THE PORTFOLIOS
 
The following investment limitations are fundamental for the Portfolios and may
not be changed without shareholder approval.
 
     1. Each Portfolio will concentrate its investments in shares of management
        investment companies.
 
     2. Each Portfolio may borrow money from banks solely for temporary
        emergency purposes, but not in an amount exceeding 30% of its total
        assets. Whenever borrowings by a Portfolio, including reverse repurchase
        agreements, exceed 5% of the value of a Portfolio's total assets, the
        Portfolio will not purchase any securities.
 
Each Portfolio is subject to further fundamental and non-fundamental
restrictions which are described in the Trust's Statement of Additional
Information.
 
   
INVESTMENT AND RISK CONSIDERATIONS OF THE UNDERLYING FUNDS, INCLUDING THE GLOBAL
MONEY FUND
    
 
   
The following section describes the distinct investment objective and policies
of each Underlying Fund and some of the risk considerations of investing in the
Underlying Funds. The "APPENDIX -- SECURITIES AND INVESTMENT PRACTICES" section
at the end of this Prospectus provides more information about the types of
securities and investment practices that the Funds may use, and the risk
considerations related to such securities and investment practices. There can be
no assurance that the Funds will achieve their respective investment objectives.
An investment in a single Fund is not designed to be a complete investment
program. In implementing its policies, each Fund uses a variety of instruments,
strategies and techniques that are described in more detail in the Appendix and
in the SAI. With respect to each Fund's investment policies, use of the term
"primarily" means that under normal circumstances, at least 65% of the Fund's
assets will be invested as indicated, except for the Global Money Fund, where
all of its assets will meet the quality and maturity standards described in the
SAI. A description of the rating systems used by the following nationally
recognized statistical rating organizations ("NRSROs") is also contained in the
SAI: Moody's, S&P, Duff & Phelps, Inc. ("Duff") and Fitch Investors Service,
Inc. ("Fitch"). New instruments, strategies and techniques, however, are
evolving continually and the Trust reserves authority to invest in or implement
them to the extent consistent with its investment objectives and policies.

THE MONEY MARKET FUND
 
GLOBAL MONEY FUND.  The Global Money Fund invests in the following U.S. dollar
denominated high-quality, money market instruments issued by U.S. and foreign
financial institutions and nonfinancial corporations and by the U.S. Government,
its agencies or instrumentalities:
 
     1. Bank Obligations;
 
     2. Commercial paper (including variable rate demand notes);
 
     3. Short-term corporate obligations;
 
     4. U.S. Government Securities; and
 
     5. Repurchase Agreements collateralized by the securities listed in 1 and 4
        above.
 
The Global Money Fund follows industry-standard guidelines on the quality and
maturity of its investments designed to help maintain a stable $1.00 share
price. The Fund does not, however, guarantee a $1.00 share price, and a major
change in interest rates or a default on an investment could cause the share
price to change. Generally, securities with longer maturities are more
vulnerable to price changes, although they provide higher yields.
 
The Fund may invest in Foreign Investments that are U.S. dollar denominated. The
Fund may invest up to 50% of its assets in any foreign country but will normally
include issues having activities in at least three countries, including the
United States. In addition, the Fund may invest in U.S. Government Securities
without limit and normally will invest at least 25% of its assets in Bank
Obligations.
 
THE BOND FUNDS
 
SHORT TERM HIGH QUALITY BOND FUND.  To accomplish its objective, the Fund will
invest primarily in high quality short-term bonds and other debt securities.
Under normal market conditions, the Fund will maintain a dollar-weighted average
portfolio maturity of three years or less. The Fund may hold individual
securities with remaining maturities of more than three years as long as the
dollar-weighted average portfolio maturity is three years or less. For purposes
of the weighted average maturity calculation, a mortgage instrument's average
life will be considered to be its maturity.
 
The Fund intends to invest substantially all of its assets in a portfolio of
debt securities that are rated investment grade by one or more NRSROs, or, if
unrated, are judged to be of comparable quality by the Fund's Sub-Advisor.
Securities which are "investment grade" are rated in one of the four highest
rating categories. The Fund will invest primarily in U.S. Government Securities,
corporate debt obligations or Mortgage-Backed Securities rated in one of the two
highest categories by an NRSRO, that is, at least Aa by Moody's, at least AA by
S&P, Duff or Fitch, or, if unrated, that are judged to be of comparable quality
by the Sub-Advisor. Investment-grade bonds are generally of medium to high
quality. A bond rated in the lower end of the category (Baa/BBB) however, may
have speculative characteristics and may be more sensitive to economic changes
and changes in the financial condition of the issuer.
 
The debt securities in which the Fund may invest include obligations issued or
guaranteed by domestic and foreign governments and government agencies and
instrumentalities and high-grade corporate debt obligations, such as bonds,
debentures, notes, equipment lease and trust certificates, Mortgage-Backed
Securities, collateralized mortgage obligations and Asset-Backed Securities.
 
   
The Fund may invest up to 10% of its assets in foreign debt securities,
primarily bonds of foreign governments or their political subdivisions, foreign
companies and supranational organizations, including non-U.S. dollar denominated
securities and U.S. dollar denominated debt securities issued by foreign issuers
and foreign branches of U.S. banks. As discussed in the Appendix under
"SECURITIES AND INVESTMENT PRACTICES -- Foreign Investments," investment in
foreign securities is subject to special risks, such as future adverse political
and economic developments; possible seizure, nationalization, or expropriation
of foreign investments; less stringent disclosure and accounting requirements;
the
    
 
                                       13
<PAGE>   18
 
possible establishment of exchange controls or taxation at the source; or the
adoption of other foreign governmental restrictions.
 
The Fund may also invest in high-quality, short-term obligations (with
maturities of 12 months or less), such as commercial paper issued by domestic
and foreign corporations, Bank Obligations and Repurchase Agreements. In
addition, the Fund may engage in certain Strategic Transactions, which include
Dollar Roll Transactions, Reverse Repurchase Agreements, Interest Rate
Transactions, Options on Securities and Indexes, Futures and Options on Futures,
Options on Foreign Currencies, Foreign Exchange Transactions and Over the
Counter Options. The Fund currently intends to invest up to 10% of its total
assets in Reverse Repurchase Agreements and up to 33 1/3% of its total assets in
Dollar Roll Transactions.
 
Although the Fund will invest in high quality investments and maintain a
dollar-weighted average portfolio maturity of three years or less, there will be
some variation in the extent to which the values of the Fund's investments will
vary in response to changes in generally prevailing interest rates. For example,
certain Mortgage-Backed Securities, collateralized mortgage obligations and
Asset-Backed Securities may have pre-payment features that tend to make their
values increase less in response to declining interest rates and decrease more
in response to increasing interest rates than would the values of otherwise
similar conventional debt securities. The Fund may also invest in "inverse
floater" instruments that may be more volatile than other variable rate debt
instruments.
 
   
The Fund may invest in certain illiquid securities.
    
 
SHORT TERM GLOBAL GOVERNMENT FUND.  The Fund invests primarily in at least three
different countries, one of which may be the United States. The Fund maintains a
dollar-weighted average portfolio maturity not exceeding three years but may
hold individual securities with longer maturities. This policy helps minimize
the effect of interest rate changes on the Fund's share price. The Sub-Advisor's
determination of the expected average life of a portfolio mortgage security is
used as that security's maturity with regard to determining the above
calculation of average dollar-weighted portfolio maturity. The Fund's share
price and yield will fluctuate primarily due to the movement of foreign
currencies against the U.S. dollar and changes in worldwide interest rates.
 
The Fund is not meant to be a substitute for a money market fund, which seeks to
maintain a fixed net asset value per share. The Fund seeks to maintain greater
price stability than longer-term bond funds.
 
   
Under normal market conditions, the Fund will invest primarily in: (i)
obligations issued or guaranteed by foreign national governments, their
agencies, instrumentalities, or political subdivisions (including any security
which is majority owned by such government, agency, instrumentality, or
political subdivision); and (ii) U.S. Government Securities. The Fund may also
invest in non-government foreign and domestic debt securities, including debt
securities issued or guaranteed by Supranational Organizations, corporate debt
securities, Bank Obligations, Mortgage-Backed or Asset-Backed Securities, and
Repurchase Agreements.
    
 
To protect against credit risk, the Fund invests primarily in high-grade debt
securities. At least 65% of the Fund's investments will consist of securities
rated within the three highest rating categories of S&P (AAA, AA, A) or Moody's
(Aaa, Aa or A) or, if unrated, will be considered by the Sub-Advisor to be of
equivalent quality. The Fund may invest in Lower-Rated Securities.
 
In addition to U.S. dollar holdings, the Fund may invest in securities
denominated in foreign currencies and in multinational currency units, such as
the European Currency Unit ("ECU"), which is a "basket" consisting of specified
amounts of the currencies of certain states of the European Community. The
specific amounts of currencies comprising the ECU may be adjusted by the Council
of Ministers of the European Community to reflect changes in the relative values
of the underlying currencies. Securities of issuers within a given country may
be denominated in the currency of another country. In addition, when the Fund's
Sub-Advisor believes that U.S. securities offer superior opportunities for
achieving the
 
                                       14
<PAGE>   19
 
Fund's investment objective, or for temporary defensive purposes, the Fund may
invest substantially all of its assets in securities of U.S. issuers or
securities denominated in U.S. dollars.
 
The Fund may engage in certain Strategic Transactions, which include Reverse
Repurchase Agreements, Interest Rate Transactions, Options on Securities and
Indexes, Futures and Options on Futures, Options on Foreign Currencies, Foreign
Exchange Transactions and Over the Counter Options. The Fund may also invest up
to 33 1/3% of its total assets in Dollar Roll Transactions.
 
The Fund's net asset value per share fluctuates, depending on (i) current
worldwide market interest rates, (ii) the value of the currencies in which the
Fund's portfolio securities are denominated when compared to the U.S. dollar,
(iii) the success of the Sub-Advisor's currency hedging techniques, and (iv) the
creditworthiness of the issuers in which the Fund is invested. In pursuing the
Fund's investment objective, however, the Sub-Advisor actively manages the Fund
in an effort to minimize the effect of such factors on the Fund's net asset
value per share. The Sub-Advisor allocates the Fund's investments among those
markets, issuers and currencies that it believes offer the most attractive
combination of high income and principal stability. In evaluating investments
for the Fund, the Sub-Advisor analyzes relative yields and appreciation
potential of securities in particular markets; world interest rates and monetary
trends; economic, political and financial market conditions in different
countries; credit quality; and the relationship of individual foreign currencies
to the U.S. dollar. The Sub-Advisor relies on internally and externally
generated financial, economic, and credit research to evaluate alternative
investment opportunities. In addition, Sierra Advisors may, from time to time,
direct the Sub-Advisor with respect to investment strategies and specific Fund
investments including, but not limited to, the Fund's currency hedging strategy,
U.S. dollar currency exposure and certain investments which are unrated or rated
below investment grade.
 
The Short Term Global Government Fund is classified as a "non-diversified"
investment company under the Investment Company Act of 1940, as amended (the
"1940 Act"), which means that the Fund is not limited by the 1940 Act in the
proportion of its assets that may be invested in the obligations of a single
issuer. The Fund may assume large positions in the obligations of a small number
of issuers which may subject the Fund to greater credit and other risks than a
more broadly diversified portfolio. The Fund must, however, meet certain
diversification standards to qualify as a regulated investment company under the
Internal Revenue Code of 1986, as amended (the "Code"). See "Taxes" in the SAI.
 
U.S. GOVERNMENT FUND.  Under normal market conditions, the Fund pursues its
objective by investing at least 65% and up to 100% of its assets in
intermediate- and long-term U.S. Government Securities. Depending on current
market conditions, the Fund may invest in U.S. Government Securities of varying
maturities, which may range up to 40 years. Securities in the Fund's portfolio
are high quality securities that will generally yield less income than lower
quality securities; higher quality securities, however, generally have less
credit and market risk and are more readily marketable than lower quality
securities. Depending on market conditions, the Fund's portfolio will consist of
various types of U.S. Government Securities in varying proportions. The Fund may
invest up to 35% of its assets in (i) Commercial Mortgage-Backed Securities
rated in one of the two highest rating categories by an NRSRO, that is, at least
Aa by Moody's, at least AA by S&P, Duff or Fitch, or, if unrated, that are
judged to be of comparable quality by the Sub-Advisor; and (ii) the types of
securities in which the Corporate Income Fund may invest except as otherwise
prohibited in this Prospectus or the SAI, including preferred stock, Convertible
Securities, U.S. Government Securities (including Government Stripped
Mortgage-Backed Securities), Asset-Backed Securities and interests in Lease
Obligations Bonds. A substantial portion of the Fund's assets at any time may
consist of Mortgage-Backed Securities. For more detailed information regarding
the types of securities in which the Corporate Income Fund may invest, see
"Corporate Income Fund."
 
The Fund may invest up to 20% of its assets in money market instruments
consisting of short-term U.S. Government Securities and Repurchase Agreements
with respect to such U.S. Government Securities, and for temporary defensive
purposes may invest in these instruments without limitation. In addition,
 
                                       15
<PAGE>   20
 
the Fund may engage in Reverse Repurchase Agreements and certain Strategic
Transactions. The Fund may also invest up to 33 1/3% of its total assets in
Dollar Roll Transactions.
 
GUARANTEES OF THE FUND'S SECURITIES BY THE U.S. GOVERNMENT, ITS AGENCIES OR
INSTRUMENTALITIES GUARANTEE ONLY THE PAYMENT OF PRINCIPAL AND INTEREST ON THE
GUARANTEED SECURITIES, AND DO NOT GUARANTEE THE SECURITIES' YIELD OR VALUE OR
THE YIELD OR VALUE OF THE FUND'S SHARES.
 
CORPORATE INCOME FUND.  Under normal market conditions, the Fund pursues its
investment objective by investing primarily in corporate bonds of United States
issuers that are rated investment grade by one or more NRSROs, or, if not rated,
that the Fund's Sub-Advisor believes to have credit characteristics equivalent
to such investment grade rated corporate bonds. Securities that are rated
"investment grade" are rated in one of the four highest categories. Generally,
at least 65% of the corporate bonds held by the Fund will have had remaining
maturities of 10 years or more at the date of purchase, unless the Sub-Advisor
believes that investing in corporate bonds with shorter maturities would be
appropriate in light of prevailing market conditions. Corporate bonds with
longer maturities generally tend to produce higher yields and are subject to
greater market risk than debt securities with shorter maturities. The value of
the Fund's portfolio securities can be expected to vary inversely with changes
in the prevailing interest rates.
 
The Fund may also invest in preferred stock and Convertible Securities, which
are rated investment grade by an NRSRO, or, if not rated, that the Sub-Advisor
believes to have credit characteristics equivalent to such investment grade
rated bonds; U.S. Government Securities (including Government Stripped
Mortgage-Backed Securities); Asset-Backed Securities; interests in Lease
Obligation Bonds for which the payment of interest and principal is
unconditionally guaranteed by companies with debt that is rated at least
investment grade by an NRSRO, provided that, no more than 20% of the Fund's
assets will be invested in such Lease Obligation Bonds. The Fund also may invest
in bonds issued by foreign governments and corporations, provided that no more
than 20% of the Fund's assets will be invested in such bonds and no more than 5%
will be denominated in any one currency. For temporary defensive purposes, the
Fund may also invest, without limitation, in money market instruments, including
short-term U.S. Government Securities, commercial paper rated in the highest
category by an NRSRO, Bank Obligations and cash and cash equivalents. In
addition, the Fund may engage in Reverse Repurchase Agreements and certain
Strategic Transactions. The Fund may also invest up to 33 1/3% of its total
assets in Dollar Roll Transactions.
 
THE EQUITY FUNDS
 
GROWTH AND INCOME FUND.  Under normal market conditions, the Fund invests
primarily in dividend-paying Equity Securities. The Fund may also invest in
other Equity Securities, consisting of nondividend-paying Equity Securities,
preferred stock and Convertible Securities, such as convertible preferred stock,
convertible bonds rated in the highest three rating categories by Moody's or
S&P, or, if unrated, are determined to be of equal quality by the Fund's
Sub-Advisor, and warrants. The Fund is not subject to any limit on the size of
companies in which it may invest, but intends to be primarily invested, under
normal circumstances, in the large- and medium-sized companies included in the
Standard & Poor's 500 Stock Index ("S&P 500 Index"). The Fund may also invest up
to 10% of its total assets in American Depositary Receipts. The Fund is designed
for investors who want an actively managed diversified portfolio of selected
equity securities that seeks to outperform the total return of the S&P 500
Index.
 
The Fund attempts to reduce risk by investing in many different economic
sectors, industries and companies. The Fund's Sub-Advisor may under- or
over-weight selected economic sectors against the S&P 500 Index's sector
weightings to seek to enhance the Fund's total return or reduce fluctuations in
market value relative to the S&P 500 Index.
 
During ordinary market conditions, the Sub-Advisor will keep the Fund
essentially fully invested in the equity securities described above. The
Sub-Advisor may, however, invest in money market instruments including U.S.
Government Securities; Bank Obligations; and commercial paper and corporate
obliga-
 
                                       16
<PAGE>   21
 
tions, including variable rate demand notes, that are issued by U.S. and foreign
issuers and that are rated in the highest three rating categories by Moody's or
S&P, or, if unrated, are determined to be of equal quality by the Sub-Advisor.
Under normal circumstances, the Fund will invest in such money market
instruments to invest temporary cash balances or to maintain liquidity to meet
redemptions. The Fund may also, however, invest in these instruments, without
limitation, as a temporary defensive measure taken during, or in anticipation
of, adverse market conditions. In addition, the Fund may engage in certain
Strategic Transactions.
 
GROWTH FUND.  Under normal market conditions, the Fund invests primarily in
Equity Securities of U.S., multinational and foreign companies of all sizes that
offer potential for growth. Generation of income is not an objective of the
Fund, and any income received is only an incidental consideration of the Fund.
The Fund intends to invest primarily in Equity Securities believed by management
to have appreciation potential. However, no class of security represents at all
times the greatest promise for capital appreciation. Therefore, the Fund may
invest in debt securities, including Lower-Rated Securities, if in the opinion
of management, doing so would further the long-term capital appreciation
objective of the Fund.
 
The Fund may invest up to 25% of its assets in foreign securities, usually
foreign Equity Securities, and up to 5% of its assets in securities of companies
in (or governments of) developing or emerging countries (sometimes referred to
as "emerging markets"). A developing or emerging country is generally considered
by the international financial community, and in the opinion of management, to
be a country that is in the initial stages of its industrialization cycle. The
Fund may also, for temporary defensive purposes, in an effort to protect its
assets against major adverse market declines or when investment opportunities
with desirable risk/reward characteristics are unavailable, pursue a policy of
retaining cash or investing part or all of its assets in cash equivalents or
investment-grade debt securities. In addition, the Fund may engage in certain
Strategic Transactions.
 
Pursuant to an exemptive order granted by the SEC, the Growth Fund and Emerging
Growth Fund (and other funds advised by Janus Capital Corporation) may transfer
daily uninvested cash balances into one or more joint trading accounts. Assets
in the joint trading accounts are invested in money market instruments and the
proceeds are allocated to the participating funds on a pro rata basis.
 
EMERGING GROWTH FUND.  Under normal market conditions, the Fund invests
primarily in Equity Securities of companies with market capitalizations of less
than $1.4 billion at the time of purchase. Income is only an incidental
consideration of the Fund. A company's market capitalization is calculated by
multiplying the total number of shares of its Equity Securities outstanding by
the market price per share of its stock.
 
Small capitalization companies typically are subject to a greater degree of
change in earnings and business prospects than larger, more established
companies. In addition, securities of small capitalization companies are traded
in lower volume than those issued by larger companies and may be more volatile
and less liquid than those of larger companies. In light of these
characteristics of small capitalization companies and their securities, the Fund
may be subject to greater investment risk than that assumed when investing in
the equity securities of larger capitalization companies.
 
The Fund has been designed to provide investors with potentially greater
long-term rewards than those provided by an investment in a fund that seeks
capital appreciation from equity securities of larger, more established
companies. Small capitalization companies generally are not as well known to the
investing public and have less of an investor following than larger companies,
and therefore may provide opportunities for greater investment gains as a result
of relative inefficiencies in the marketplace.
 
In selecting investments for the Fund, the Fund's Sub-Advisor seeks small
capitalization companies that it believes are undervalued in the marketplace, or
that the Sub-Advisor believes have earnings that may be expected to grow faster
than the United States economy in general. These companies typically would
 
                                       17
<PAGE>   22
 
possess one or more characteristics, including high quality management, a
leading or dominant position in a major product line, a sound financial position
and a relatively high rate of return on invested capital so that future growth
can be financed from internal sources. The Fund also may invest in companies
that offer the possibility of accelerating earnings growth because of management
changes, new products or structural changes in the economy.
 
The Fund may invest up to 25% of its assets in securities of foreign issuers and
up to 5% of its assets in securities in developing or emerging countries.
 
The Fund may invest in other Equity Securities, including Convertible Securities
and warrants to purchase Equity Securities, as well as cash and cash
equivalents. In addition, the Fund may invest in Lower Rated Securities and
engage in certain Strategic Transactions. Furthermore, the Emerging Growth Fund
may transfer daily uninvested cash balances into one or more joint trading
accounts advised by the Sub-Advisor. See "Growth Fund."
 
INTERNATIONAL GROWTH FUND.  Under normal market conditions, the Fund invests
primarily in Equity Securities of foreign issuers located in countries that the
Fund's Sub-Advisor deems to have attractive investment opportunities. Income is
only an incidental consideration of the Fund. The Fund will emphasize
established companies, although it may invest in companies of varying sizes as
measured by assets, sales and capitalization.
 
   
The Fund may invest in securities of issuers located in a variety of different
foreign regions and countries which includes, but is not limited to, the
following: Argentina, Australia, Austria, Belgium, Canada, Chile, Denmark,
Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, Indonesia, Ireland,
Italy, Japan, Luxembourg, Malaysia, Mexico, The Netherlands, New Zealand,
Norway, Philippines, Poland, Portugal, Singapore, The Slovak Republic, Spain,
Sweden, Switzerland, Thailand and The United Kingdom. More than 25% of the
Fund's total assets may be invested in the securities of issuers located in the
same country. The relative strength or weakness of a particular country's
currency or economy may dictate whether securities of issuers located in such
country will be purchased or sold. Criteria for determining the appropriate
distribution of investments among various countries and regions include
prospects for relative economic growth among foreign countries, expected levels
of inflation, government policies influencing business conditions, the outlook
for currency relationships, and the range of investment opportunities available
to international investors.
    
 
The Fund invests in Equity Securities and may invest in other securities with
equity characteristics, consisting of trust or limited partnership interests,
preferred stock, rights and warrants. The Fund may also invest in Convertible
Securities. The Fund invests in securities listed on foreign or domestic
securities exchanges and securities traded in foreign or domestic
over-the-counter markets, and may invest in restricted or unlisted securities.
 
The Fund intends to stay invested in the securities described above to the
extent practical. Fund assets may be invested in short-term debt instruments to
meet anticipated day-to-day operating expenses, and for temporary defensive
purposes. In addition, when the Fund experiences large cash inflows, the Fund
may hold short-term investments pending availability of desirable equity
securities.
 
The short-term instruments in which the Fund may invest include foreign and
domestic: (i) short-term obligations of foreign governments, their agencies,
instrumentalities, authorities or political subdivisions; (ii) other short-term
debt securities rated in one of the three highest categories by an NRSRO, or if
unrated, of comparable quality in the opinion of the Fund's Sub-Advisor; (iii)
commercial paper, including master notes; (iv) Bank Obligations; and (v)
Repurchase Agreements. At the time the Fund invests in any commercial paper,
Bank Obligations or Repurchase Agreements, the issuer must have outstanding debt
rated in one of the three highest categories by an NRSRO, the issuer's parent
corporation, if any, must have outstanding commercial paper rated Prime-1 by
Moody's or A-1 by S&P; or, if no such ratings are available, the investment must
be of comparable quality in the opinion of the Fund's Sub-Advisor.
 
                                       18
<PAGE>   23
 
The Fund may invest up to 30% of its assets in the securities of companies or
governments of developing or emerging countries provided that no more than 5% of
the Fund's total assets are invested in any one such country. For temporary
defensive purposes, the Fund may invest a major portion of its assets in
securities of United States issuers. Furthermore, the Fund may invest up to 5%
of its total assets in corporate debt securities having maturities longer than
one year and which are rated BBB or better by S&P, including Euro-currency
instruments and securities.
 
In addition, the Fund may engage in certain Strategic Transactions, which
include Options on Securities and Indexes, Futures and Options on Futures,
Options on Foreign Currencies, Foreign Exchange Transactions and Over the
Counter Options.
 
   
YOUR SIERRA ASSET MANAGER CONTRACT
    
 
   
The Trust provides an active investment management service offered by Sierra
Services that allocates your investments in a combination of shares of certain
Funds that are selected to meet long-term investment objectives as well as, in
certain circumstances, current income objectives. Each Fund invests in a
diversified portfolio of securities in a manner designed to meet its own
investment objective. In addition to the considerable diversification among
individual securities you would receive by investing in a particular Fund
through the Sierra Advantage Annuity, you can further reduce risk by investing
in the Portfolios and the Global Money Fund through a Sierra Asset Manager
Contract by having your assets actively managed among several different Funds
that each have different risk and return characteristics. Sierra Services has
incorporated investment strategies into the Portfolios to meet the diverse
financial needs of different investors. You can choose one or more of the
Portfolios which allocates its assets among a number of the Funds and can choose
to invest to some extent in the Global Money Fund. The Portfolios have been
designed for long-term investors.
    
 
MANAGEMENT OF THE TRUST
 
BOARD OF TRUSTEES
 
   
The Board of Trustees is responsible for the management of the business and
affairs of the Trust as provided in the laws of the Commonwealth of
Massachusetts and the Trust's Declaration of Trust and By-Laws. The Trustees are
experienced business persons who meet several times during the year to oversee
the Trust's activities, review contractual arrangements with companies that
provide services to the Trust, and review performance. The majority of the
Trustees are not otherwise affiliated with Sierra Services, Sierra Advisors or
any of the Sub-Advisors.
    
 
   
SIERRA SERVICES, SIERRA ADVISORS, THEIR AFFILIATES AND THE PORTFOLIOS' SERVICE
PROVIDERS
    
 
INVESTMENT ADVISOR OF THE PORTFOLIOS
 
   
Under an Investment Advisory Agreement with the Trust, Sierra Services, located
at 9301 Corbin Avenue, Northridge, California 91324, is the investment advisor
of each of the Portfolios. The Advisor provides its proprietary asset allocation
services to the Portfolios, formulates the Portfolios' investment policies
(subject to the terms of this Prospectus), analyzes economic and market trends,
exercises investment discretion over the assets of the Portfolios and monitors
the allocation of each Portfolio's assets and each Portfolio's performance.
Although it is expected that each Portfolio will typically be fully invested in
the Funds, Sierra Services may, from time to time, direct the investment of each
Portfolio's cash balances in money market securities or in other instruments,
including stock or bond index futures and options thereon. For its investment
advisory services to the Portfolios, Sierra Services is entitled to a fee, which
is calculated daily and paid monthly, at an annual rate of 0.10% of each
Portfolio's average daily net assets. Sierra Services may voluntarily waive fees
payable to them from time to time.

Sierra Services became a registered broker-dealer member of the NASD and became
a registered investment advisor in 1992. Sierra Services is a wholly-owned
subsidiary of SCMC, which is a wholly-owned subsidiary of Great Western
Financial Corporation ("GWFC"). GWFC is a publicly owned financial services
company listed on the New York, London and Pacific stock exchanges. On March 6,
1997, GWFC and Washington Mutual Inc. ("Washington Mutual") announced that they
had entered into an Agreement and Plan of Merger. Washington Mutual is a
financial services company. Subject to certain conditions being met, it is
currently anticipated that the merger will close in mid-1997. Thereafter, Sierra
Services will be an indirect subsidiary of the entity formed by the merger of
Washington Mutual and GWFC. Sierra Services, which has served as an investment
advisor to another investment company, since 1996 the Sierra Asset Management
Portfolios, has provided asset allocation services to individual Sierra Asset
Management accounts since 1992, and had aggregate assets under management of
approximately $833 million as of December 31, 1996.
    
 
   
Stephen C. Scott, Senior Vice President of the Trust since 1993 and of Sierra
Services since 1996, is the portfolio manager of each of the Portfolios. He

Sierra Advisors since 1989. Prior to joining GW Securities, he served as
President and Chairman of SDS Investment Advisors, a firm he founded in which he
developed asset allocation technology. Mr. Scott has had primary management
responsibility for the Portfolios since their inception.
    
 
   
DISTRIBUTOR
    
 
   
Sierra Services also serves as the distributor of the Trust's shares on a best
efforts basis. Sierra Services, as principal underwriter, or insurance companies
whose variable products are funded by the Trust, will bear all of the Trust's
marketing expenses. This includes the cost of reproducing prospectuses,
statements of additional information or any other Trust documents (such as
semi-annual reports) used as sales materials. Sierra Services makes payments to
AGL to assist it in defraying various costs involved in offering the Portfolios
under its contracts.

assets. Sierra Administration pays FDISG a fee based on the average daily assets
of the Trust and its expenses for its services as sub-administrator. In
addition, Sierra Administration pays the basic fees and charges of Boston Safe.
Sierra Administration may voluntarily waive fees payable to it and reimburse
expenses from time to time. During the fiscal year ended December 31, 1996, each
Fund paid fees to Sierra Administration equal to 0.18% of the average net assets

INVESTMENT ADVISOR OF THE UNDERLYING FUNDS
    
 
   
Sierra Advisors, located at 9301 Corbin Avenue, Northridge, California 91324, is
the investment advisor of the Underlying Funds. Responsibilities of Sierra
Advisors include formulating the Funds' investment policies (subject to the
terms of this Prospectus), analyzing economic trends and directing and
evaluating the investment services provided by the Sub-Advisors and monitoring
each Fund's investment performance. Each Fund has a sub-advisor who selects the
investments made by the Fund subject to oversight and direction by Sierra
Advisors. In connection with these activities, Sierra Advisors may initiate
action to change a Sub-Advisor if it deems such action to be in the best
interests of a Fund and its shareholders. Sierra Advisors became a registered
investment advisor in 1988. Sierra Advisors is a wholly-owned subsidiary of
SCMC, which is a wholly-owned subsidiary of GWFC.

The management fees for the Short Term Global Government, Growth and Income,
Growth, Emerging Growth and International Growth Funds are higher than those
paid by most mutual funds, but comparable to other mutual funds with like
investment objectives and policies.
    
 
   
Sierra Advisors or certain Fund Sub-Advisors may voluntarily waive fees payable
to them from time to time. Any fee waivers by a Sub-Advisor may be retained by
Sierra Advisors, or Sierra Advisors may pass part or all of such fee waivers
through to the Underlying Funds. Sierra Advisors and the Administrator of the
Funds have each voluntarily undertaken to waive its fees and/or bear certain
expenses, if necessary, from time to time so that average annual total expenses
of the Funds will not exceed 0.85%, 1.45%, 1.30%, 1.40%, 1.55%, 1.10%, 1.00%,
1.15% and 1.35% for the Global Money, Growth, Growth and Income, Emerging
Growth, International Growth, U.S. Government, Short Term High Quality Bond,
Corporate Income and Short Term Global Government Funds, respectively. Absent
these voluntary waivers and reimbursements and credits allowed by the custodian,
the annual management fees, other expenses and total expenses for the Global
Money Fund would be 0.50%, 0.38% and 0.88%, respectively. Expenses for a Fund
may be accrued at a rate in excess of such limits for short periods of time so
long as the limit is met on an annual basis. Actual expenses for a Portfolio or
a Fund may vary from day to day. Sierra Advisors and the Administrator retain
the ability to be repaid by a Fund if expenses fall below the specified limit
prior to the end of the fiscal year, but will not recover these amounts in later
years. Sierra Advisors and the Administrator may each, at its sole discretion,
vary the level of or eliminate its voluntary fee waivers and expense
reimbursements at any time. Waivers of fees and reimbursement of expenses have
the effect of increasing yield or improving total return for the period when
such waivers and reimbursements are in effect. During the fiscal year ended
December 31, 1996, the following fees based upon the average net assets of each
Fund were paid by the Trust to Sierra Advisors: Global Money Fund: 0.20%; Short
Term High Quality Bond Fund: 0.42%; Short Term Global Government fund: 0.75%;
U.S. Government Fund: 0.60%; Corporate Income Fund: 0.65%; Growth and Income
Fund: 0.80%; Growth Fund: 0.89%; Emerging Growth Fund: 0.87% and International
Growth Fund: 0.94%.
    
 
   
PORTFOLIO TRANSACTIONS AND TURNOVER.  All orders for the purchase or redemption
of shares of the Underlying Funds are placed by Sierra Advisors. All orders for
the purchase or sale of other securities on behalf of a Portfolio or a Fund are
placed by Sierra Advisors or the Fund's Sub-Advisor, respectively, with
broker-dealers that it selects. A Fund may, at the discretion of Sierra Advisors
or the Fund's Sub-Advisor, utilize broker-dealers affiliated with Sierra
Advisors or a Sub-Advisor in connection with a purchase or sale of securities,
in accordance with procedures adopted by Trustees and in accordance with the
1940 Act which require periodic review of these transactions.
    
 
   
Under certain market conditions, an Underlying Fund may experience high
portfolio turnover as a result of its investment strategies. For example, the
purchase or sale of securities by a Fund in anticipation of a
    
 
                                       22
<PAGE>   27
 
   
rise or decline in interest rates or to take advantage of yield disparities
among different issues of U.S. Government Securities could result in high
portfolio turnover. As a result of their investment strategies, the Short Term
High Quality Bond, Short Term Global Government, U.S. Government and Growth
Funds' annual portfolio turnover rates are expected to be as high as 200%.
Higher portfolio turnover rates for the Funds can result in corresponding
increases in expenses such as brokerage commissions and transaction costs. The
Funds will not consider portfolio turnover rate a limiting factor in making
investment decisions consistent with their respective objectives and policies.
    
 
   
INVESTMENT SUB-ADVISORS OF THE UNDERLYING FUNDS
    
 
   
The following organizations, under the supervision of Sierra Advisors, serve as

Like any investment company, each Portfolio and each Underlying Fund pays
expenses related to its daily operations. Expenses paid out of an investment
company's assets are reflected in its share price or dividends; they are neither
billed directly to shareholders nor deducted from shareholder accounts. Each
Portfolio pays a management fee to Sierra Services for managing its investments
and business affairs and each Underlying Fund pays a management fee to Sierra
Advisors for managing its investments and business affairs. Sierra Advisors pays
fees to the Investment Sub-Advisors, who provide assistance with these services.
Each Portfolio and each Underlying Fund also pays other expenses, which are
explained on the following pages. Sierra Services, Sierra Advisors and/or Sierra
Administration may, from time to time, agree to waive management fees or
reimburse expenses above a specified limit.
    
 
   
GENERAL INFORMATION AND HISTORY
    
 
THE TRUST
 
The Trust is an open-end management investment company that offers diversified
and non-diversified series. It was organized on January 29, 1993 under the laws
of the Commonwealth of Massachusetts as a "Massachusetts business trust." The
Trust has the power to issue separate series of shares and has authorized 14
separate series. The Trust offers shares of beneficial interest, each without
par value. Additional series may be established.
 
   
Currently, the shares of the Portfolios are sold only to AGL and its separate
accounts to fund Sierra Asset Manager Contracts and shares of the Underlying
Funds, are sold only to the Portfolios and to separate accounts of AGL. In the
future, the Trust may offer its shares to separate accounts funding variable
annuities of insurance companies affiliated or unaffiliated with AGL and to
separate accounts which fund variable life insurance or other variable funding
arrangements. The Trust's Board of Trustees will monitor potential conflicts
between variable life insurance policies and variable annuity contracts or among
insurance company shareholders and will determine what, if any, action should be
taken to resolve any conflicts. Until other insurance companies have made
investments in the Portfolios or the Funds, AGL will be the sole shareholder of
the Trust.
    
 
Under Massachusetts law, in certain circumstances, shareholders may be held
personally liable as partners for the obligations of a business trust such as
the Trust. The Trust's Declaration of Trust contains provisions designed to
protect shareholders from such liability to the extent of the Trust's assets. As
a result, the risk of personal liability for insurance companies or Portfolios
as shareholders is remote.
 
   
SHAREHOLDER MEETINGS AND VOTING OF SHARES
    
 
   
As a Massachusetts business trust, the Trust is not required to hold annual
shareholders' meetings. On occasion, however, special meetings may be called to
elect or remove trustees, change fundamental policies, approve management
contracts, or for other purposes. Generally, shares of the Trust vote by
individual Portfolio or Fund on all matters except when the 1940 Act permits
shares of the Portfolios or Funds to be voted in the aggregate. When matters are
submitted for shareholder vote, shareholders of each Portfolio or Fund will have
one vote for each full share owned and proportionate, fractional votes for
fractional shares held. The shareholders of the Portfolios are insurance
companies whose separate accounts invest in the Portfolios. The shareholders of
the Funds are the Portfolios that invest in the Funds and insurance companies
whose separate accounts invest in the Funds. AGL has advised the Trust that,
whenever a shareholder vote is taken, AGL will give Sierra Asset Manager
Contract owners and annuitants the opportunity to instruct them how to vote the
number of shares attributable to such
    
 
                                       26
<PAGE>   31
 
   
contracts. AGL also stated that it will vote any shares that it is entitled to
vote directly, because of their attributable interests in the Trust, and any
shares attributable to Sierra Asset Manager Contracts for which instructions are
not received, in the same proportion that Sierra Asset Manager Contract owners
vote. Matters may be submitted by the Funds for vote by the shareholders of the
Funds, in which case the Portfolios, as shareholders of the Funds, will be
entitled to vote the shares they hold. Each Portfolio will vote its Fund shares
in proportion to the votes of all other shareholders of each respective Fund.
    
 
   
PURCHASE AND REDEMPTION
    
 
   
The shares of the Portfolios and the Global Money Fund are sold in a continuous
offering to AGL for its separate accounts to fund Sierra Asset Manager
Contracts. Net purchase payments under the Sierra Asset Manager Contracts are
placed in one or more of the divisions of the insurance company separate
accounts and are invested in the shares of the Portfolios or the Global Money
Fund corresponding to such divisions. Shares of the Portfolios and the Global
Money Fund are purchased and redeemed by the insurance company at net asset
value without sales or redemption charges.
    
 
   
All purchase and redemption orders will be processed in accordance with
applicable regulations. The Trust may also suspend redemption, if permitted
under the 1940 Act, for any period during which the New York Stock Exchange
("NYSE") is closed or during which trading is restricted by the SEC or the SEC
declares that an emergency exists. Redemption may also be suspended during other
periods permitted by the SEC for the protection of the Trust's shareholders.
    
 
   
From time to time, one or more of the separate account investment divisions may
experience relatively large purchases or redemptions due to allocations or
rebalancings recommended by Sierra Services for the Portfolios. These
transactions may affect the Underlying Funds in which the Portfolios invest,
since Funds that experience redemptions as a result of reallocations or
rebalancings in the Portfolio may have to sell portfolio securities and Funds
that receive additional cash will have to invest it. While it is impossible to
predict the overall impact of these transactions over time, there could be
adverse effects on Funds' portfolio management to the extent that Funds may be
required to sell securities or invest cash at times when they would not
otherwise do so. These transactions could also increase transaction costs.
Sierra Advisors, representing the interests of the Trust, is committed to
minimizing the impact of Portfolio transactions on the Funds; Sierra Services,
representing the interests of Portfolio shareholders, is also committed to
minimizing such impact on the Funds to the extent it is consistent with pursuing
the investment objectives of the Portfolios. Sierra Services and Sierra Advisors
will nevertheless face conflicts in fulfilling their respective
responsibilities, because they are affiliates and employ some of the same
professionals. In addition, Sierra Services is also the Trust's Distributor and
has contracted with American General Securities Incorporated, the principal
underwriter of the Sierra Asset Manager Contracts, for Sierra Services to
distribute the Sierra Asset Manager Contracts and the Sierra Advantage
Contracts. Although Sierra Services is not compensated for sales of Trust
shares, it is compensated for sales of the Sierra Asset Manager Contracts and
the Sierra Advantage Contracts.
    
 
   
TRUST EXPENSES
    
 
   
Each Portfolio and Underlying Fund pays all expenses not assumed by Sierra
Services or Sierra Advisors. Such expenses include or could include
investment-related expenses, such as brokers' commissions, transfer taxes and
fees related to the purchase, sale, or loan of securities; fees and expenses for
Trustees not affiliated with Sierra Services, Sierra Advisors or the
Sub-Advisors; fees and expenses of its independent auditors and legal counsel;
costs of Trustee and shareholder meetings; SEC fees; expenses of preparing and
filing registration statements; the cost of the printing and mailing of proxy
statements, prospectuses and statements of additional information; proxy
solicitors' fees; expenses of preparation, printing and mailing of semi-annual
shareholder reports; bank transaction charges and certain custodians' fees and
expenses; federal, state or local income or other taxes; costs of maintaining
the Trust's corporate existence; membership fees for the Investment Company
Institute and similar organizations; fidelity
    
 
                                       27
<PAGE>   32
 
   
bond and Trustees' liability insurance premiums; and any extraordinary expenses
such as indemnification payments or damages awarded in litigation or settlements
made. All these expenses will be passed on to the shareholders through a daily
charge made to the assets held in the Portfolios and the Funds, which will be
reflected in share prices.
    
 
NET ASSET VALUE
 
   
The net asset value (the current market value of a Fund share) of each
Portfolio's and Underlying Fund's shares is determined at the close of regular
trading on the NYSE (currently 1:00 p.m., Pacific Time), each business day the
NYSE is open, except as noted. The NYSE is currently scheduled to be closed on
New Year's Day, President's Day, Good Friday, Memorial Day, Independence Day,
Labor Day, Thanksgiving Day and Christmas Day, and on the preceding Friday or
subsequent Monday when one of these holidays falls on a Saturday or Sunday,
respectively. In addition, net asset values will not be calculated on the Friday
following Thanksgiving. Net asset value per share is calculated for purchases
and redemptions of shares of each Portfolio or Fund by dividing the value of
total Portfolio or Fund assets, less liabilities (including Trust expenses,
which are accrued daily), by the total number of shares of that Portfolio or
Fund outstanding. The net asset value per share of each Portfolio or Fund is
determined each business day at the close of business. Values of assets in each
Portfolio's and Fund's portfolio (except the Global Money Fund and certain
short-term debt securities) are determined on the basis of their market values
or valuations determined as described in the SAI. The Global Money Fund values
its assets by the amortized cost method, which approximates market value.
    
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
 
   
The tax consequences of your investment in the Trust depend upon the specific
provisions of your Sierra Asset Manager Contract. For more information, see the
attached Prospectus for that Sierra Asset Manager Contract. The following
discussion is only a brief summary of the federal income tax consequences to the
Portfolios and the Underlying Funds and their insurance company and Portfolio
shareholders based on current tax laws and regulations, which may be changed by
subsequent legislative, judicial, or administrative action.
    
 
Each Portfolio and Fund intends to qualify separately each year as a "regulated
investment company" ("RIC") as defined under Subchapter M of the Code. The
requirements for qualification may cause a portfolio or Fund to restrict the
extent of its short-term trading or its transactions in options or futures
contracts.
 
As a RIC, each Portfolio or Fund will not be subject to federal income tax on
its net investment income and net realized capital gains which are timely
distributed to its insurance company shareholders. Accordingly, each Portfolio
or Fund intends to distribute all or substantially all of its net investment
income and net realized capital gains to its shareholders. Very generally, an
insurance company which is a shareholder of a Fund will determine its federal
income tax liability with respect to distributions from that Fund pursuant to
the special rules of Subchapter L of the Code.
 
Although the Trust intends that it and each Portfolio and Fund will be operated
so that they will have no federal income tax liability, if any such liability is
nevertheless incurred, the investment performance of that Portfolio or Fund
incurring such liability will be adversely affected. In addition, Portfolios or
Funds investing in foreign securities and currencies may be subject to foreign
taxes. These taxes would reduce the investment performance of such Portfolios or
Funds.
 
Because the Trust funds certain types of variable annuities, each Portfolio and
Fund is also subject to the investment diversification requirements of
Subchapter L of the Code. Were any Portfolio or Fund to fail to comply with
those requirements, owners of annuity contracts (other than certain
tax-qualified retirement Contracts) funded through the Trust would be taxed on
investment earnings under their
 
                                       28
<PAGE>   33
 
Contracts and would thereby lose any benefit of tax deferral. Accordingly, the
Trust will carefully monitor compliance with the diversification requirements.
 
   
The amounts of dividends of net investment income (i.e., all income other than
long-term and short-term capital gains) and distributions of net realized long
and short-term capital gains payable to shareholders will be determined
separately for each Portfolio or Fund. Dividends and distributions paid by a
Portfolio or Fund will be automatically reinvested (at current net asset value)
in additional full and fractional shares of that Portfolio or Fund. Each of the
Income Portfolio, Value Portfolio, Balanced Portfolio and Global Money Fund
intends to distribute its net income as dividends for each day that net asset
value is determined. Such dividends will be declared daily and paid monthly.
Each of the Growth Portfolio, Short Term High Quality Bond, Short Term Global
Government, U.S. Government and Corporate Income Funds will declare and pay
quarterly dividends from net investment income, the Capital Growth Portfolio and
the Growth and Income, Growth, Emerging Growth and International Growth Funds
will declare and pay such dividends annually. All Portfolios and Funds will
distribute any net long-term capital gains annually. Distributions of any net
short-term capital gains earned by a Portfolio or Fund will be distributed no
less frequently than annually at the discretion of the Board of Trustees.
    
 
   
PERFORMANCE
    
 
   
The Trust may, from time to time, calculate the yield and effective yield of the
Global Money Fund, the yield of Portfolios or the other Underlying Funds or
total return of all Portfolios and Funds, and may include such information in
reports to shareholders. Performance information should be considered in light
of the Portfolio's or Fund's investment objectives and policies, characteristics
and quality of the portfolios, and the market conditions during the given time
period, and should not be considered as a representation of what may be achieved
in the future.
    
 
Current yield for the Global Money Fund will be based on income received by a
hypothetical investment over a given 7-day period (less expenses accrued during
the period), and then annualized (i.e., assuming that the 7-day yield would be
received for 52 weeks, stated in terms of an annual percentage return on the
investment). Effective yield for the Global Money Fund is calculated in a manner
similar to that used to calculate yield, but reflects the compounding effect of
earnings on reinvested dividends. For the Portfolios and remaining Funds, any
quotations of yield will be based on all investment income per share earned
during a given 30-day period (including dividends and interest), less expenses
accrued during the period (net investment income), and will be computed by
dividing net investment income by the maximum public offering price per share on
the last day of the period. Quotations of average annual total return for a
Portfolio or Fund will be expressed in terms of the average annual compounded
rate of return on a hypothetical investment in the Portfolio or Fund over
certain periods that will include periods of 1, 5, and 10 years (up to the life
of the Portfolio or Fund), will reflect the deduction of a proportional share of
Trust's expenses (on an annual basis), and will assume that all dividends and
distributions are reinvested when paid.
 
Total returns and yields quoted for the Portfolio or Funds include each
Portfolio's or Fund's expenses, but may not include charges and expenses
attributable to any particular insurance product. Since shares of the Portfolios
and Funds may only be purchased through variable annuity and variable life
insurance contracts, you should carefully review the prospectus of the insurance
product you have chosen for information on relevant charges and expenses.
Excluding these charges from quotations of each Portfolio's or Fund's
performance has the effect of increasing the performance quoted. You should bear
in mind the effect of these charges when comparing a performance to that of
other mutual funds.

SECURITIES AND INVESTMENT PRACTICES
 
   
In attempting to achieve its investment objective or policies each Portfolio and
Underlying Fund employs a variety of instruments, strategies and techniques,
which are described in greater detail below. Risks and restrictions associated
with these practices are also described. Policies and limitations are considered
at the time a security or instrument is purchased or a practice initiated.
Generally, securities need not be sold if subsequent changes in market value
would prevent applicable limitations to be met.
    
 
   
An Underlying Fund might not buy all of these securities or use all of these
techniques to the full extent permitted unless its Sub-Advisor, subject to
oversight by Sierra Advisors, believes that doing so will help the Fund achieve
its goal. Sierra Advisors may, from time to time, direct a Sub-Advisor with
respect to investment policies and strategies.
    
 
   
Except for the limitations on borrowing, the investment guidelines set forth
below may be changed at any time without shareholder consent by vote of the
Board of Trustees of the Trust. A complete list of investment restrictions,
including fundamental restrictions that cannot be changed without the approval
of a majority of an affected Portfolio's or Underlying Fund's outstanding shares
is contained in the SAI.
    
 
AMERICAN DEPOSITARY RECEIPTS, EUROPEAN DEPOSITARY RECEIPTS, CONTINENTAL
DEPOSITARY RECEIPTS AND GLOBAL DEPOSITARY RECEIPTS
 
All Funds except the U.S. Government Fund may invest in securities of foreign
issuers directly or in the form of American Depositary Receipts ("ADRs"),
European Depositary Receipts ("EDRs"), Continental Depositary Receipts ("CDRs")
and Global Depositary Receipts ("GDRs") or other similar securities representing
securities of foreign issuers. These securities may not necessarily be
denominated in the same currency as the securities they represent. ADRs are
receipts typically issued by a United States bank or trust company evidencing
ownership of the underlying foreign securities. EDRs, which are sometimes
referred to as CDRs, are securities, typically issued by a non-U.S. financial
institution, that evidence ownership interests in a security or a pool of
securities issued by either a U.S. or foreign issuer. GDRs are issued globally
and evidence a similar ownership arrangement. Generally, ADRs, in registered
form, are designed for use in the United States securities markets, and EDRs, in
bearer form, are designed for use in European securities markets.
 
ASSET-BACKED SECURITIES
 
The Short Term High Quality Bond, Short Term Global Government, U.S. Government,
Corporate Income and Growth and Income Funds may purchase Asset-Backed
Securities, which represent a participation in, or are secured by and payable
from, a stream of payments generated by particular assets, most often a pool of
assets similar to one another. Assets generating such payments will consist of
motor vehicle installment purchase obligations, credit card receivables and home
equity loans. The Short Term High Quality Bond Fund will not invest more than
25%, and the Short Term Global Government, U.S. Government, Corporate Income and
Growth and Income Funds will not invest more than 10%, of their respective total
assets in Asset-Backed Securities.
 
BANK OBLIGATIONS
 
All of the Funds may invest in Bank Obligations, which include certificates of
deposit, time deposits and bankers' acceptances of U.S. commercial banks or
savings and loan institutions with assets of at least $500 million as of the end
of their most recent fiscal year. All of the Funds, except the Global Money and
U.S. Government Funds, may invest in foreign-currency denominated Bank
Obligations, including Euro-currency instruments and securities of U.S. and
foreign banks and thrifts. The Global Money Fund may invest in U.S. dollar
denominated Bank Obligations of foreign banks and thrifts.
 
                                       A-1

BORROWING
 
The Funds may borrow money for temporary or emergency purposes. However, if a
Fund borrows money, its share price may be subject to greater fluctuation until
the borrowing is paid off. If the Fund makes additional investments while
borrowings are outstanding, this may be construed as a form of leverage.
 
A Fund may borrow money from banks solely for temporary or emergency purposes,
but not in an amount exceeding 30% of its total assets. For each of the Funds
except the Short Term High Quality Bond, Short Term Global Government, U.S.
Government, Corporate Income, Growth and Income and Emerging Growth Funds,
whenever borrowings by a Fund, including Reverse Repurchase Agreements, exceed
5% of the value of a Fund's total assets, the Fund will not purchase any
securities. The Short Term High Quality Bond, Short Term Global Government, U.S.
Government, Corporate Income, Growth and Income and Emerging Growth Funds are
prohibited from borrowing money or entering Reverse Repurchase Agreements or
Dollar Roll Transactions in the aggregate in excess of 33 1/3% of the Fund's
total assets (after giving effect to such borrowings). This investment guideline
may be changed only with shareholder consent.
 
Borrowing, including reverse repurchase agreements and, in certain
circumstances, dollar rolls, creates leverage which increases a Fund's
investment risk. If the income and gains on the securities purchased with the
proceeds of borrowings exceed the cost of the arrangements, the Fund's earnings
or net asset value will increase faster than would be the case otherwise.
Conversely, if the income and gains fail to exceed the costs, earnings or net
asset value will decline faster than would otherwise be the case.
 
CONVERTIBLE SECURITIES
 
A convertible security is a security that may be converted either at a stated
price or rate within a specified period of time into a specified number of
shares of Equity Securities. By investing in Convertible Securities, the Fund
seeks the opportunity, through the conversion feature, to participate in the
capital appreciation of the Equity Securities into which the securities are
convertible, while obtaining a higher fixed rate of return than generally is
payable on the underlying Equity Securities.
 
CURRENCY MANAGEMENT
 
A Fund's flexibility to participate in higher yielding debt markets outside of
the United States may allow the Fund to achieve higher yields than those
generally obtained by domestic money market funds and short-term bond
investments. When a Fund invests significantly in securities denominated in
foreign currencies, however, movements in foreign currency exchange rates versus
the U.S. dollar are likely to impact the Fund's share price stability relative
to domestic short-term income funds. Fluctuations in foreign currencies can have
a positive or negative impact on returns. Normally, to the extent that the Fund
is invested in foreign securities, a weakening in the U.S. dollar relative to
the foreign currencies underlying a Fund's investments should help increase the
net asset value of the Fund. Conversely, a strengthening in the U.S. dollar
versus the foreign currencies in which a Fund's securities are denominated will
generally lower the net asset value of the Fund. The Fund's Sub-Advisor may
attempt to minimize exchange rate risk through active portfolio management,
including hedging currency exposure through the use of futures, options and
forward currency transactions and may attempt to identify bond markets with
strong or stable currencies.
 
DEBT SECURITIES ISSUED OR GUARANTEED BY SUPRANATIONAL ORGANIZATIONS
 
Funds authorized to invest in securities of foreign issuers may invest assets in
debt securities issued or guaranteed by Supranational Organizations, such as
obligations issued or guaranteed by the Asian Development Bank, Inter-American
Development Bank, International Bank for Reconstruction and Development (World
Bank), African Development Bank, European Coal and Steel Community, European
Economic Community, European Investment Bank and the Nordic Investment Bank.

DOLLAR ROLL TRANSACTIONS
 
   
Any Bond Fund may enter into dollar rolls or "covered rolls" in which the Fund
sells securities (usually Mortgage-Backed Securities) and simultaneously
contracts to purchase, typically in 30 or 60 days, substantially similar, but
not identical, securities on a specified future date. The proceeds of the
initial sale of securities in the Dollar Roll Transactions may be used to
purchase long-term securities which will be held during the roll period. During
the roll period, the Fund forgoes principal and interest paid on the securities
sold at the beginning of the roll period, but may earn interest on the
reinvested cash proceeds of the initial sale. The Fund is compensated either by
the difference between the current sales price and the forward price for the
future purchase (often referred to as the "drop"), or by a fee paid by the
dealer at the time of the initial sale. A "covered roll" is a specific type of
dollar roll for which there is an offsetting cash position or cash equivalent
securities position that matures on or before the forward settlement date of the
Dollar Roll Transaction. As used herein the term "dollar roll" refers to dollar
rolls that are not "covered rolls." At the end of the roll commitment period,
the Fund may or may not take delivery of the securities the Fund has contracted
to purchase. The risks of engaging in Dollar Roll Transactions include the
following: If the dealer to whom the Fund sells the security becomes insolvent,
the Fund's right to purchase or repurchase the security may be restricted; the
value of the security may change adversely over the term of the dollar roll; the
security that the Fund is required to repurchase may be worth less than the
security that the Fund originally held; and the return earned by the Fund with
the proceeds of a dollar roll may not exceed transaction costs.
    
 
The Fund will establish a segregated account with its custodian in which it will
maintain cash, U.S. Government Securities or other liquid high-grade debt
obligations equal in value at all times to its obligations in respect of dollar
rolls, and, accordingly, the Fund will not treat such obligations as senior
securities for purposes of the 1940 Act. "Covered rolls" are not subject to
these segregation requirements. Dollar Roll Transactions may be considered
borrowings and are, therefore, subject to the borrowing limitations applicable
to the Funds. See "Borrowing." Each of the Short Term High Quality Bond, Short
Term Global Government, U.S. Government and Corporate Income Funds may invest up
to 33 1/3% of its total assets in such transactions.
 
EQUITY SECURITIES
 
The Equity, U.S. Government and Corporate Income Funds may invest in Equity
Securities or rights to acquire Equity Securities. Equity Securities represent
an equity (ownership) interest in a corporation, which generally gives a Fund
the right to vote on measures affecting the company's organization and
operations.
 
Equity Securities include common stock, preferred stock and securities
exchangeable for shares of common stock, such as convertible debt, convertible
preferred stock and warrants.
 
EXCHANGE RATE-RELATED SECURITIES
 
A Fund may invest in securities that are indexed to certain specific foreign
currency exchange rates. The terms of such security provide that the principal
amount or interest payments are adjusted upwards or downwards (but not below
zero) at payment to reflect fluctuations in the exchange rate between two
currencies while the obligation is outstanding, depending on the terms of the
specific security. The Fund will purchase such security with the currency in
which it is denominated and will receive interest and principal payments thereon
in the currency, but the amount of principal or interest payable by the issuer
will vary in proportion to the change (if any) in the exchange rate between the
two specified currencies between the date the instrument is issued and the date
the principal or interest payment is due. The staff of the SEC is currently
considering whether a mutual fund's purchase of this type of security would
result in the issuance of a "senior security" within the meaning of the 1940
Act. The Fund believes that such investments do not involve the creation of such
a senior security, but nevertheless undertakes, pending the resolution of this
issue by the staff, to establish a segregated account with respect to such
investments
 
                                       A-3
<PAGE>   37
 
and to maintain in such account cash not available for investment or U.S.
Government Securities or other liquid high quality debt securities having a
value equal to the aggregate principal amount of outstanding securities of this
type.
 
Investments in Exchange Rate-Related Securities entail certain risks. There is
the possibility of significant changes in rates of exchange between the U.S.
dollar and any foreign currency to which an Exchange Rate-Related Security is
linked. In addition, there is no assurance that sufficient trading interest to
create a liquid secondary market will exist for a particular Exchange
Rate-Related Security due to conditions in the debt and foreign currency
markets. Illiquidity in the forward foreign exchange market and the high
volatility of the foreign exchange market may from time to time combine to make
it difficult to sell an Exchange Rate-Related Security prior to maturity without
incurring a significant price loss.
 
FIXED-INCOME SECURITIES
 
The market value of fixed-income obligations held by the Portfolios or the Funds
and, consequently, the net asset value per share of the Funds can be expected to
vary inversely to changes in prevailing interest rates. Investors should also
recognize that, in periods of declining interest rates, the yields of the Bond
Funds will tend to be somewhat higher than prevailing market rates and, in
periods of rising interest rates, the Bond Funds' yields will tend to be
somewhat lower. Also, when interest rates are falling, the inflow of net new
money to the Bond Funds from the continuous sale of their shares will likely be
invested in instruments producing lower yields than the balance of their assets,
thereby reducing current yields. In periods of rising interest rates, the
opposite can be expected to occur. In addition, obligations purchased by certain
of the Bond Funds that are rated in the lowest of the top four ratings (Baa by
Moody's or BBB by S&P, Duff or Fitch) are considered to have speculative
characteristics and changes in economic conditions or other circumstances are
more likely to lead to a weakened capacity to make principal and interest
payments than is the case with higher grade securities.
 
FLOATING RATE, INVERSE FLOATING RATE AND VARIABLE RATE OBLIGATIONS
 
The Corporate Income and Short Term High Quality Bond Funds may purchase
floating rate, inverse floating rate and variable rate obligations, including
Mortgage-Backed Securities. Floating rate obligations have an interest rate that
changes whenever there is a change in the external interest rate, while variable
rate obligations provide for a specified periodic adjustment in the interest
rate. The interest rate on an inverse floating rate obligation (an "inverse
floater") can be expected to move in the opposite direction from the market rate
of interest to which the inverse floater is indexed. The Fund may purchase
floating rate, inverse floating rate and variable rate obligations that carry a
demand feature which would permit the Fund to tender them back to the issuer or
remarketing agent at par value prior to maturity. Frequently, floating rate,
inverse floating rate and variable rate obligations are secured by letters of
credit or other credit support arrangements provided by banks.
 
An inverse floater may be considered to be leveraged to the extent that its
interest rate varies by a magnitude that exceeds the magnitude of the change in
the index rate of interest. The higher degree of leverage inherent in inverse
floaters is associated with greater volatility in their market values.
Accordingly, the duration of an inverse floater may exceed its stated final
maturity.
 
The Global Money Fund may purchase variable rate demand notes issued by
industrial development authorities and other governmental entities, as well as
participation interests therein. Although variable rate demand notes are
frequently not rated by credit rating agencies, a Fund may purchase unrated
notes that are determined by the Fund's Sub-Advisor to be of comparable quality
at the time of purchase to rated instruments that may be purchased by the Fund.
Moreover, while there may be no active secondary market with respect to a
particular variable rate demand note purchased by a Fund, the Fund may, upon the
notice specified in the note, demand payment of the principal of and accrued
interest on the note at any time and may resell the note at any time to a third
party. The absence of such an active
 
                                       A-4
<PAGE>   38
 
secondary market, however, could make it difficult for a Fund to dispose of a
particular variable rate demand note in the event the issuer of the note
defaulted on its payment obligations, and the Fund could, for this or other
reasons, suffer a loss to the extent of the default.
 
FOREIGN CURRENCY EXCHANGE TRANSACTIONS
 
All Funds except the Global Money and U.S. Government Funds may engage in
foreign currency exchange transactions. Funds that buy and sell securities
denominated in currencies other than the U.S. dollar, and receive interest,
dividends and sale proceeds in currencies other than the U.S. dollar, may enter
into foreign currency exchange transactions to convert to and from different
foreign currencies and to convert foreign currencies to and from the U.S.
dollar. The Fund either enters into these transactions on a spot (i.e., cash)
basis at the spot rate prevailing in the foreign currency exchange market, or
uses forward contracts to purchase or sell foreign currencies.
 
A forward foreign currency exchange contract is an obligation by the Fund to
purchase or sell a specific currency at a future date, which may be any fixed
number of days from the date of the contract. Forward foreign currency exchange
contracts establish an exchange rate at a future date. These contracts are
transferable in the interbank market conducted directly between currency traders
(usually large commercial banks) and their customers. A forward foreign currency
exchange contract generally has no deposit requirement, and is traded at a net
price without commission. Except in circumstances where segregated accounts are
not required by the 1940 Act and the rules adopted thereunder, each Fund
maintains with its custodian a segregated account of cash, U.S. Government
Securities or high-grade debt obligations in an amount at least equal to its
obligations under each forward foreign currency exchange contract. Neither spot
transactions nor forward foreign currency exchange contracts eliminate
fluctuations in the prices of the Fund's portfolio securities or in foreign
exchange rates, or prevent loss if the prices of these securities should
decline.
 
A Fund may enter into foreign currency transactions in an attempt to protect
against changes in foreign currency exchange rates between the trade and
settlement dates of specific securities transactions or changes in foreign
currency exchange rates that would adversely affect a portfolio position or an
anticipated portfolio position. Although these transactions tend to minimize the
risk of loss due to a decline in the value of the hedged currency, at the same
time they tend to limit any potential gain that might be realized should the
value of the hedged currency increase. The precise matching of the forward
contract amounts and the value of the securities involved will not generally be
possible because the future value of these securities in foreign currencies will
change as a consequence of market movements in the value of those securities
between the date the forward contract is entered into and the date it matures.
The projection of currency market movements is extremely difficult, and the
successful execution of a hedging strategy is highly uncertain. In addition,
when the Sub-Advisor believes that the currency of a specific country may
deteriorate against another currency, it may enter into a forward contract to
sell the less attractive currency and buy the more attractive one. The amount in
question could be less than or equal to the value of the Fund's securities
denominated in the less attractive currency. The Fund may also enter into a
forward contract to sell a currency which is linked to a currency or currencies
in which some or all of the Fund's portfolio securities are or could be
denominated, and to buy U.S. dollars. These practices are referred to as "cross
hedging" and "proxy hedging."
 
Forward currency exchange contracts are agreements to exchange one currency for
another -- for example, to exchange a certain amount of U.S. dollars for a
certain amount of Japanese Yen -- at a future date and specified price.
Typically, the other party to a currency exchange contract will be a commercial
bank or other financial institution. Because there is a risk of loss to the Fund
if the other party does not complete the transaction, the Fund's Sub-Advisor
will enter into foreign currency exchange contracts only with parties approved
by the Fund's Board of Trustees.
 
A Fund may maintain "short" positions in forward currency exchange transactions
in which the Fund agrees to exchange currency that it currently does not own for
another currency -- for example, to
 
                                       A-5
<PAGE>   39
 
exchange an amount of Japanese Yen that it does not own for a certain amount of
U.S. dollars -- at a future date and specified price in anticipation of a
decline in the value of the currency sold short relative to the currency that
the Fund has contracted to receive in the exchange.
 
To the extent that such actions are intended to protect the Fund from adverse
currency movements, there is a risk that currency movements involved will not be
properly anticipated. Use of this technique may also be limited by management's
need to protect the status of the Fund as a regulated investment company under
the Code. The projection of currency market movements is extremely difficult,
and the successful execution of currency strategies is highly uncertain.
 
FOREIGN INVESTMENTS
 
   
All of the Funds except the U.S. Government Fund may invest in securities of
foreign issuers. There are certain risks involved in investing in foreign
securities, including those resulting from fluctuations in currency exchange
rates, devaluation of currencies, future political or economic developments and
the possible imposition of currency exchange blockages or other foreign
governmental laws or restrictions, reduced availability of public information
concerning issuers, and the fact that foreign companies are not generally
subject to uniform accounting, auditing and financial reporting standards or to
other regulatory practices and requirements comparable to those applicable to
domestic companies. Moreover, securities of many foreign companies may be less
liquid and the prices more volatile than those of securities of comparable
domestic companies. Although the Funds' Sub-Advisors do not intend to expose the
Funds to such risks, with respect to certain foreign countries, there is the
possibility of expropriation, nationalization, confiscatory taxation and
limitations on the use or removal of funds or other assets of the Funds,
including the withholding of dividends. In addition, because many foreign stock
exchanges are open at times when U.S. Securities Markets are closed, such as
certain federal holidays, the value of a Fund's investment in foreign securities
may fluctuate without being immediately reflected in the Fund's NAV.
    
 
   
Because foreign securities generally are denominated and pay dividends or
interest in foreign currencies, and the Funds hold various foreign currencies
from time to time, the value of the net assets of the Funds as measured in U.S.
dollars will be affected favorably or unfavorably by changes in exchange rates.
The cost of the Funds' currency exchange transactions will generally be the
difference between the bid and offer spot rate of the currency being purchased
or sold. In order to protect against uncertainty in the level of future foreign
currency exchange rates, the Funds are authorized to enter into certain foreign
currency exchange transactions. Investors should be aware that exchange rate
movements can be significant and can endure for long periods of time. The
Sub-Advisors of the Short Term Global Government and International Growth Funds
attempt to manage exchange rate risk through active Currency Management.
Extensive research of the economic, political and social factors that influence
global markets is conducted by the Sub-Advisors. Particular attention is given
to country-specific analysis, reviewing the strength or weakness of a country's
overall economy, the government policies influencing business conditions and the
outlook for the country's currency. When the Fund's Sub-Advisor believes that
currency in which a portfolio security or securities is denominated may suffer a
decline against the U.S. dollar, it may hedge such risk by entering into a
forward contract to sell an amount of foreign currency approximating the value
of some or all of the Fund's portfolio securities denominated in such foreign
currency.
    
 
In addition, while the volume of transactions effected on foreign stock
exchanges has increased in recent years, in most cases it remains appreciably
below that of the NYSE. Accordingly, the Funds' foreign investments may be less
liquid and their prices may be more volatile than comparable investments in
securities of United States companies. Moreover, the settlement periods for
foreign securities, which are often longer than those for securities of United
States issuers, may affect portfolio liquidity. In buying and selling securities
on foreign exchanges, the Fund normally pays fixed commissions that are
generally higher than the negotiated commissions charged in the United States.
In addition, there is generally less
 
                                       A-6
<PAGE>   40
 
governmental supervision and regulation of securities exchanges, brokers and
issuers in foreign countries than in the United States.
 
FUTURES AND OPTIONS ON FUTURES
 
   
When deemed advisable by Sierra Services to meet liquidity needs or temporary
defensive purposes, each Portfolio may, and when deemed advisable by its
Sub-Advisor, each Fund, except the Global Money Fund, may enter into financial
futures and related options that are traded on a U.S. exchange or board of
trade. If entered into, these transactions may be made for the purpose of
hedging against the effects of changes in the value of portfolio securities due
to anticipated changes in interest rates and market conditions, when
transactions are economically appropriate to the reduction of risks inherent in
the management of the Portfolios and the Funds and, for the Funds, for other
purposes described under "Strategic Transactions." A Portfolio or Fund may not
enter into futures and options contracts for which aggregate initial margin
deposits and premiums paid for unexpired futures options entered into for
purposes other than "bona fide hedging" positioning as defined in regulations
adopted by the Commodities Future Trading Commission exceed 5% of the fair
market value of the Fund's assets, after taking into account unrealized profits
and unrealized losses on futures contracts into which it has entered. With
respect to each long position in a futures contract or option thereon, the
underlying commodity value of such contract will always be covered by cash and
cash equivalents set aside plus accrued profits held at the futures commission
merchant.
    
 
A financial futures contract provides for the future sale by one party and the
purchase by the other party of a specified amount of a particular financial
instrument (debt security) at a specified price, date, time and place. An index
futures contract is an agreement pursuant to which two parties agree to take or
make delivery of an amount of cash equal to the difference between the value of
the index at the close of the last trading day of the contract and the price at
which the index contract was originally written. An option on a financial or
index futures contract generally gives the purchaser the right, in return for
the premium paid, to assume a position in a futures contract at a specified
exercise price at any time prior to the expiration date of the option.
 
   
The purpose of entering into a futures contract by a Portfolio or Fund is to
either enhance return or to protect the Fund from fluctuations in the value of
its securities caused by anticipated changes in interest rate or market
conditions without necessarily buying or selling the securities. The use of
futures contracts and options on futures contracts involves several risks. There
can be no assurance that there will be a correlation between price movements in
the underlying securities, currencies or index, and price movements in the
securities which are the subject of the futures contracts or options on futures
contracts. Positions in futures contracts and options on futures contracts may
be closed out only on the exchange or board of trade on which they were entered
into, and there can be no assurance that an active market will exist for a
particular contract or option at any particular time. If a Portfolio or Fund has
hedged against the possibility of an increase in interest rates or bond prices
adversely affecting the value of securities held in its portfolio and rates or
prices decreased instead, the Portfolio or Fund will lose part or all of the
benefit of the increased value of securities that it has hedged because it will
have offsetting losses in its futures positions. In addition, in such
situations, if a Portfolio or Fund has insufficient cash, it may have to sell
securities to meet daily variation margin requirements at a time when it may be
disadvantageous to do so. These sales of securities may, but will not
necessarily, be at increased prices that reflect the decline in interest rates
or bond prices, as the case may be. In addition, the Portfolio or Fund would pay
commissions and other costs in connection with such investments, which may
increase the Portfolio's or Fund's expenses and reduce its return. While
utilization of options, futures contracts and similar instruments may be
advantageous to the Portfolio or Fund, if Sierra Services or the Fund's
Sub-Advisor is not successful in employing such instruments in managing the
Portfolio's or Fund's investments, the Portfolio's or Fund's performance will be
worse than if the Fund did not make such investments.

<PAGE>   41
 
Losses incurred in futures contracts and options on futures contracts and the
costs of these transactions will adversely affect a Portfolio's or Fund's
performance.
 
GEOGRAPHICAL AND INDUSTRY CONCENTRATION
 
The Global Money Fund will invest at least 25% of its assets in Bank Obligations
unless the Fund is in a temporary defensive position. As a result of this
concentration policy, which is a fundamental policy of the Fund, the Fund's
investments may be subject to greater risk than a fund that does not concentrate
in the banking industry. In particular, Bank Obligations may be subject to the
risks associated with interest rate volatility, changes in federal and state
laws and regulations governing banking and the inability of borrowers to pay
principal and interest when due. In addition, foreign banks present the risks of
investing in foreign securities generally and are not subject to reserve
requirements and other regulations comparable to those of U.S. Banks.
 
   
GOVERNMENT STRIPPED MORTGAGE-BACKED SECURITIES
    
 
All of the Funds may invest in Government Stripped Mortgage-Backed Securities
issued or guaranteed by the Government National Mortgage Association ("GNMA"),
Federal National Mortgage Association ("FNMA") and Federal Home Loan Mortgage
Corporation ("FHLMC"). These securities represent beneficial ownership interests
in either periodic principal distributions ("principal-only") or interest
distributions ("interest-only") on mortgage-backed certificates issued by GNMA,
FNMA or FHLMC, as the case may be. The certificates underlying the Government
Stripped Mortgage-Backed Securities represent all or part of the beneficial
interest in pools of mortgage loans. The Funds will invest in interest-only
Government Stripped Mortgage-Backed Securities in order to enhance yield or to
benefit from anticipated appreciation in value of the securities at times when
the appropriate Sub-Advisor believes that interest rates will remain stable or
increase. In periods of rising interest rates, the value of interest-only
Government Stripped Mortgage-Backed Securities may be expected to increase
because of the diminished expectation that the underlying mortgages will be
prepaid. In this situation the expected increase in the value of interest-only
Government Stripped Mortgage-Backed Securities may offset all or a portion of
any decline in value of the portfolio securities of the Funds. Investing in
Government Stripped Mortgage-Backed Securities involves the risks normally
associated with investing in Mortgage-Backed Securities issued by government or
government-related entities. See "Mortgage-Backed Securities" in this section.
In addition, the yields on interest-only and principal-only Government Stripped
Mortgage-Backed Securities are extremely sensitive to the prepayment experience
on the mortgage loans underlying the certificates collateralizing the
securities. If a decline in the level of prevailing interest rates results in a
rate of principal prepayments higher than anticipated, distributions of
principal will be accelerated, thereby reducing the yield to maturity on
interest-only Government Stripped Mortgage-Backed Securities and increasing the
yield to maturity on principal-only Government Stripped Mortgage-Backed
Securities. Conversely, if an increase in the level of prevailing interest rates
results in a rate of principal prepayments lower than anticipated, distributions
of principal will be deferred, thereby increasing the yield to maturity on
interest-only Government Stripped Mortgage-Backed Securities and decreasing the
yield to maturity on principal-only Government Stripped Mortgage-Backed
Securities. Sufficiently high prepayment rates could result in the Fund not
fully recovering its initial investment in an interest-only Government Stripped
Mortgage-Backed Security. Government Stripped Mortgage-Backed Securities are
currently traded in an over-the-counter market maintained by several large
investment banking firms. There can be no assurance that the Fund will be able
to effect a trade of a Government Stripped Mortgage-Backed Security at a time
when it wishes to do so. The Funds will acquire Government Stripped
Mortgage-Backed Securities only if a liquid secondary market for the Securities
exists at the time of acquisition.

ILLIQUID SECURITIES
 
Up to 15% (10% for the Global Money Fund) of the net assets of a Fund may be
invested in securities that are not readily marketable, including, where
applicable: (1) Repurchase Agreements with maturities greater than seven
calendar days; (2) time deposits maturing in more than seven calendar days; (3)
to the extent a liquid secondary market does not exist for the instruments,
futures contracts and options thereon; (4) certain over-the-counter options, as
described in the SAI; (5) certain variable rate demand notes having a demand
period of more than seven days; and (6) securities the disposition of which is
restricted under federal securities laws (excluding Rule 144A Securities,
described below). The Funds will not include for purposes of the restrictions on
illiquid investments securities sold pursuant to Rule 144A under the Securities
Act of 1933, as amended, so long as such securities meet liquidity guidelines
established by the Trust's Board of Trustees. Under Rule 144A, securities which
would otherwise be restricted may be sold by persons other than issuers or
dealers to qualified institutional buyers.
 
INTEREST RATE TRANSACTIONS
 
All of the Funds except the Global Money Fund may engage in certain Interest
Rate Transactions, such as swaps, caps, floors and collars. Interest rate swaps
involve the exchange with another party of commitments to pay or receive
interest (e.g., an exchange of floating rate payments for fixed rate payments).
The purchase of an interest rate cap entitles the purchaser, to the extent that
a specified index exceeds a predetermined interest rate, to receive payments of
interest on a notional principal amount from the party selling such interest
rate cap. The purchase of an interest rate floor entitles the purchaser, to the
extent that a specified index falls below a predetermined interest rate, to
receive payments of interest on a notional principal amount from the party
selling such interest rate floor. An interest rate collar combines the elements
of purchasing a cap and selling a floor. The collar protects against an interest
rate rise above the maximum amount but gives up the benefits of an interest rate
decline below the minimum amount. The net amount of the excess, if any, of a
Fund's obligations over its entitlements with respect to each interest rate swap
will be accrued on a daily basis and an amount of cash or liquid securities
having an aggregate net asset value at least equal to the accrued excess will be
maintained in a segregated account by the Trust's custodian. If there is a
default by the other party to the transaction, the Fund will have contractual
remedies pursuant to the agreements related to the transactions.
 
INVESTMENT COMPANIES
 
When a Fund's Sub-Advisor believes that it would be beneficial to the Fund and
appropriate under the circumstances, the Sub-Advisor may invest up to 10% of the
Fund's assets in securities of mutual funds that are not affiliated with Sierra
Advisors or any Sub-Advisor. As a shareholder in any such mutual fund, the Fund
will bear its ratable share of the mutual fund's expenses, including management
fees, and will remain subject to the Fund's advisory and administration fees
with respect to the assets so invested.
 
LEASE OBLIGATION BONDS
 
Lease Obligation Bonds are mortgages on a facility that is secured by the
facility and are paid by a lessee over a long term. The rental stream to service
the debt as well as the mortgage are held by a collateral trustee on behalf of
the public bondholders. The primary risk of such instrument is the risk of
default. Under the lease indenture, the failure to pay rent is an event of
default. The remedy to cure default is to rescind the lease and sell the asset.
If the lease obligation is not readily marketable or market quotations are not
readily available, such lease obligations will be subject to a Fund's 15% (10%
for the Global Money Fund) limit on Illiquid Securities.
 
                                       A-9
<PAGE>   43
 
LENDING OF SECURITIES
 
All of the Funds except the U.S. Government Fund have the ability to lend
portfolio securities to brokers and other financial organizations. By lending
its securities, a Fund can increase its income by continuing to receive interest
on the loaned securities as well as by either investing the cash collateral in
short-term instruments or obtaining yield in the form of interest paid by the
borrower when U.S. Government Securities are used as collateral. These loans, if
and when made, may not exceed 20% of a Fund's total assets taken at value. Loans
of portfolio securities by a Fund will be collateralized by cash, letters of
credit or U.S. Government Securities that are maintained at all times in an
amount at least equal to the current market value of the loaned securities. Any
gain or loss in the market price of the securities loaned that might occur
during the term of the loan would be for the account of the Fund involved. Each
Fund's Sub-Advisor will monitor on an ongoing basis the creditworthiness of the
institutions to which the Fund lends securities.
 
LOWER-RATED SECURITIES
 
The Growth and Emerging Growth Funds may each invest up to 35%, and the Short
Term Global Government Fund up to 10%, of its total assets in debt securities
rated below the fourth highest rating by an NRSRO or of equivalent quality as
determined by the Sub-Advisor. Non-investment-grade debt securities are
securities rated BB or lower and are commonly referred to as "junk bonds."
 
Securities rated below investment grade as well as unrated securities are often
considered to be speculative and usually entail greater risk (including the
possibility of default or bankruptcy of the issuers). Such securities generally
involve greater price volatility and risk of principal and income, and may be
less liquid, than securities in higher rated categories. Both price volatility
and illiquidity may make it difficult for the Fund to value certain of these
securities at certain times and these securities may be difficult to sell under
certain market conditions. Prices for non-investment-grade debt securities may
be affected by legislative and regulatory developments. For further information,
see "Investment Objectives and Policies of the Funds -- Strategy Available to
Short Term Global Government, Growth and Emerging Growth Funds" in the SAI and
the Appendix.
 
MORTGAGE-BACKED SECURITIES
 
All of the Funds may invest in Mortgage-Backed Securities, which represent an
interest in a pool of mortgage loans. The primary government issuers or
guarantors of Mortgage-Backed Securities are GNMA, FNMA and FHLMC.
Mortgage-Backed Securities provide a monthly payment consisting of interest and
principal payments. Additional payments may be made out of unscheduled
repayments of principal resulting from the sale of the underlying residential
property, refinancing or foreclosure, net of fees or costs that may be incurred.
Prepayments of principal on Mortgage-Backed Securities may tend to increase due
to refinancing of mortgages as interest rates decline. Prompt payment of
principal and interest on GNMA mortgage pass-through certificates is backed by
the full faith and credit of the U.S. Government. FNMA-guaranteed mortgage
pass-through certificates and FHLMC participation certificates are solely the
obligations of those entities but are supported by the discretionary authority
of the U.S. Government to purchase the agencies' obligations. Collateralized
Mortgage Obligations are a type of bond secured by an underlying pool of
mortgages or mortgage pass-through certificates that are structured to direct
payments on underlying collateral to different series or classes of the
obligations. In addition, the U.S. Government Fund may invest in commercial
Mortgage-Backed Securities, which are similar to the above Mortgage-Backed
Securities, except they are issued by non-governmental entities and are created
by pooling together commercial and multifamily mortgage loans into trusts that
are structured into different classes or series based upon the prioritization of
cash flows. Commercial Mortgage-Backed Securities include Collateralized
Mortgage Obligations and real estate mortgage investment conduits ("REMICs").
While commercial Mortgage-Backed Securities are generally struc-
 
                                      A-10
<PAGE>   44
 
tured with one or more types of credit enhancements, they typically lack a
guarantee by an entity having the credit status of a governmental agency or
instrumentality.
 
To the extent that a Fund purchases mortgage-related or mortgage-backed
securities at a premium, prepayments may result in some loss of the Fund's
principal investment to the extent of the premium paid. The yield of the Fund
may be affected by reinvestment of prepayments at higher or lower rates than the
original investment. In addition, like other debt securities, the value of
mortgage-related securities, including government and government-related
mortgage pools, will generally fluctuate in response to market interest rates.
 
NEW ISSUERS
 
A Fund may invest up to 5% of its assets in the securities of issuers which have
been in continuous operation for less than three years.
 
OPTIONS ON SECURITIES
 
   
OPTION PURCHASE.  Each Fund, except the Global Money Fund, may purchase put and
call options, on portfolio securities in which it may invest, that are traded on
a U.S. or foreign securities exchange or in the over-the-counter market. A Fund
may utilize up to 10% of its assets to purchase put options on portfolio
securities and may do so at or about the same time that it purchases the
underlying security or at a later time. By buying a put, the Funds limit their
risk of loss from a decline in the market value of the security until the put
expires. Any appreciation in the value of the underlying security, however, will
be partially offset by the amount of the premium paid for the put option and any
related transaction costs. A Fund may also utilize up to 10% of its assets to
purchase call options on securities in which it is authorized to invest. Call
options may be purchased by the Fund in order to acquire the underlying
securities for the Fund at a price that avoids any additional cost that would
result from a substantial increase in the market value of a security. The Funds
may also purchase call options to increase their return to investors at a time
when the call is expected to increase in value due to anticipated appreciation
of the underlying security. Prior to their expirations, put and call options may
be sold in closing sale transactions (sales by the Fund, prior to the exercise
of options that it has purchased, of options of the same series), and profit or
loss from the sale will depend on whether the amount received is more or less
than the premium paid for the option plus the related transaction costs.
    
 
COVERED OPTION WRITING.  All Funds except the Global Money Fund may write put
and call options on securities for hedging purposes. The Funds realize fees
(referred to as "premiums") for granting the rights evidenced by the options. A
put option embodies the right of its purchaser to compel the writer of the
option to purchase from the option holder an underlying security at a specified
price at any time during the option period. In contrast, a call option embodies
the right of its purchaser to compel the writer of the option to sell to the
option holder an underlying security at a specified price at any time during the
option period.
 
Upon the exercise of a put option written by a Fund, the Fund may suffer a loss
equal to the difference between the price at which the Fund is required to
purchase the underlying security and its market value at the time of the option
exercise, less the premium received for writing the option. Upon the exercise of
a call option written by the Fund, the Fund may suffer a loss equal to the
excess of the security's market value at the time of the option exercise over
the Fund's acquisition cost of the security, less the premium received for
writing the option.
 
   
The U.S. Government and Corporate Income Funds may also write covered options on
portfolio securities to enhance current return. Accordingly, whenever a Fund
writes a call option, it will continue to own or have the present right to
acquire the underlying security without the payment of additional consideration
for as long as it remains obligated as the writer of the option. To support its
obligation to purchase the underlying security if a put option is written, the
Fund will either (1) deposit with Boston
    
 
                                      A-11
<PAGE>   45
 
Safe in a segregated account cash, U.S. Government Securities or other
short-term high-grade debt obligations having a value at least equal to the
exercise price of the underlying securities or (2) continue to own an equivalent
number of puts on the same "series" (that is, puts on the same underlying
security having the same exercise prices and expiration dates as those written
by the Fund), or an equivalent number of puts on the same "class" (that is, puts
on the same underlying security) with exercise prices greater than those that it
has written (or, if the exercise prices of the puts it holds are less than the
exercise prices of those it has written, it will deposit the difference with
Boston Safe in a segregated account).
 
The principal reason for writing covered call and put options on portfolio
securities is to attempt to realize, through the receipt of premiums, a greater
return than would be realized on the securities alone. In return for a premium,
the writer of a covered call option forfeits the right to any appreciation in
the value of the underlying security above the strike price for the life of the
option (or until a closing purchase transaction can be effected). Nevertheless,
the call writer retains the risk of a decline in the price of the underlying
security. Similarly, the principal reason for writing covered put options is to
realize income in the form of premiums. The writer of the covered put option
accepts the risk of a decline in the price of the underlying security. The size
of the premiums that the Funds may receive may be adversely affected as new or
existing institutions, including other investment companies, engage in or
increase their option-writing activities.
 
The Funds may engage in closing purchase transactions to realize a profit, to
prevent an underlying security from being called or put or, in the case of a
call option, to unfreeze an underlying security (thereby permitting its sale or
the writing of a new option on the security prior to the outstanding option's
expiration). To effect a closing purchase transaction, the Funds would purchase,
prior to the holder's exercise of an option that the Fund has written, an option
of the same series as that on which the Fund desires to terminate its
obligation. The obligation of the Fund under an option that it has written would
be terminated by a closing purchase transaction, but the Fund would not be
deemed to own an option as the result of the transaction. There can be no
assurance that the Fund will be able to effect closing purchase transactions at
a time when it wishes to do so. The ability of the Fund to engage in closing
transactions with respect to options depends on the existence of a liquid
secondary market. While the Fund will generally purchase or write options only
if there appears to be a liquid secondary market for the options purchased or
sold, for some options no such secondary market may exist or the market may
cease to exist. To facilitate closing purchase transactions, however, the Fund
will ordinarily write options only if a secondary market for the options exists
on a U.S. securities exchange or in the over-the-counter market.
 
Option writing for the Funds may be limited by position and exercise limits
established by U.S. securities exchanges and the National Association of
Securities Dealers, Inc. and by requirements of the Code for qualification as a
regulated investment company. In addition to writing covered put and call
options to generate current income, the Funds may enter into options
transactions as hedges to reduce investment risk, generally by making an
investment expected to move in the opposite direction of a portfolio position. A
hedge is designed to offset a loss on a portfolio position with a gain on the
hedge position; at the same time, however, a properly correlated hedge will
result in a gain on the portfolio position's being offset by a loss on the hedge
position. The Funds bear the risk that the prices of the securities being hedged
will not move in the same amount as the hedge. A Fund will engage in hedging
transactions only when deemed advisable by its Sub-Advisor. Successful use by
the Fund of options will depend on its Sub-Advisor's ability to correctly
predict movements in the direction of the stock underlying the option used as a
hedge. Losses incurred in hedging transactions and the costs of these
transactions will adversely affect the Fund's performance.

OPTIONS ON FOREIGN CURRENCIES
 
A Fund may purchase and write put and call options on foreign currencies for the
purpose of hedging against declines in the U.S. dollar value of foreign
currency-denominated portfolio securities and against increases in the U.S.
dollar cost of such securities to be acquired. Generally, transactions relating
to Options on Foreign Currencies occur in the over-the-counter market. As in the
case of other kinds of options, however, the writing of an option on a foreign
currency constitutes only a partial hedge, up to the amount of the premium
received, and the Fund could be required to purchase or sell foreign currencies
at disadvantageous exchange rates, thereby incurring losses. The purchase of an
option on a foreign currency may constitute an effective hedge against
fluctuations in exchange rates, although, in the event of rate movements adverse
to the Fund's position, it may forfeit the entire amount of the premium plus
related transaction costs. There is no specific percentage limitation on the
Fund's investments in Options on Foreign Currencies. See the SAI for further
discussion of the use, risks and costs of Options on Foreign Currencies and Over
the Counter Options.
 
OPTIONS ON INDEXES
 
A Fund may, subject to applicable securities regulations, purchase and write put
and call options on stock and fixed income indexes listed on foreign and
domestic stock exchanges. A stock index fluctuates with changes in the market
values of the stocks included in the index. An example of a domestic stock index
is the S&P 500 Index. Examples of foreign stock indexes are the Canadian Market
Portfolio Index (Montreal Stock Exchange), The Financial Times -- Stock Exchange
100 (London Stock Exchange) and the Toronto Stock Exchange Composite 300
(Toronto Stock Exchange). Examples of fixed-income indexes include the Lehman
Government/Corporate Bond Index and the Lehman Treasury Bond Index.
 
Options on Indexes are generally similar to options on securities except for
delivery requirements. Instead of giving the right to take or make delivery of a
security at a specified price, an option on an index gives the holder the right
to receive a cash "exercise settlement amount" equal to (a) the amount, if any,
by which the fixed exercise price of the option exceeds (in the case of a put)
or is less than (in the case of a call) the closing value of the underlying
index on the date of exercise, multiplied by (b) a fixed "index multiplier."
Receipt of this cash amount will depend upon the closing level of the index upon
which the option is based being greater than, in the case of a call, or less
than, in the case of a put, the exercise price of the option. The amount of cash
received will be equal to such difference between the closing price of the index
and the exercise price of the option expressed in dollars or a foreign currency,
as the case may be, times a specified multiple. The writer of the option is
obligated, in return for the premium received, to make delivery of this amount.
The writer may offset its position in index options prior to expiration by
entering into a closing transaction on an exchange or the option may expire
unexercised.
 
The effectiveness of purchasing or writing index options as a hedging technique
will depend upon the extent to which price movements in the portion of the
securities portfolio of the Fund correlate with price movements of the stock
index selected. Because the value of an index option depends upon movements in
the level of the index rather than the price of a particular stock, whether the
Fund will realize a gain or loss from the purchase or writing of options on an
index depends upon movements in the level of stock prices in the stock market
generally or, in the case of certain indexes, in an industry or market segment,
rather than movements in the price of a particular stock. Accordingly,
successful use of Options on Indexes by the Fund will be subject to its
Sub-Advisor's ability to predict correctly movements in the direction of the
market generally or of a particular industry. This requires different skills and
techniques than predicting changes in the price of individual stocks.
 
Options on securities indexes entail risks in addition to the risks of options
on securities. Because exchange trading of options on securities indexes is
relatively new, the absence of a liquid secondary market to close out an option
position is more likely to occur, although the Fund generally will only purchase
or write such an option if the Sub-Advisor believes the option can be closed
out. Because options on securities indexes require settlement in cash, the Fund
may be forced to liquidate portfolio
 
                                      A-13
<PAGE>   47
 
securities to meet settlement obligations. The Fund will engage in stock index
options transactions only when determined by its Sub-Advisor to be consistent
with its efforts to control risk. There can be no assurance that such judgment
will be accurate or that the use of these portfolio strategies will be
successful.
 
When the Fund writes an option on an index, it will establish a segregated
account with Boston Safe or with a foreign sub-custodian in which the Fund will
deposit cash or cash equivalents or a combination of both in an amount equal to
the market value of the option, and will maintain the account while the option
is open.
 
OVER THE COUNTER OPTIONS
 
All Funds except the Global Money Fund may write or purchase options in
privately negotiated domestic or foreign transactions ("OTC Options"), as well
as exchange-traded or "listed" options. OTC Options can be closed out only by
agreement with the other party to the transaction, and thus any OTC Options
purchased by a Fund will be considered an Illiquid Security. In addition,
certain OTC Options on foreign currencies are traded through financial
institutions acting as market-makers in such options and the underlying
currencies.
 
OTC Options entail risks in addition to the risks of exchange-traded options.
Exchange-traded options are in effect guaranteed by the Options Clearing
Corporation while a Fund relies on the party from whom it purchases an OTC
Option to perform if the Fund exercises the option. With OTC Options, if the
transacting dealer fails to make or take delivery of the securities or amount of
foreign currency underlying an option it has written, in accordance with the
terms of that option, the Fund will lose the premium paid for the option as well
as any anticipated benefit of the transaction. Furthermore, OTC Options are less
liquid than exchange-traded options.
 
REPURCHASE AGREEMENTS
 
Repurchase Agreements are agreements to purchase underlying debt obligations
from financial institutions, such as banks and broker-dealers, subject to the
seller's agreement to repurchase the obligations at an established time and
price. The collateral for such Repurchase Agreements will be held by the
custodian of the Portfolio or Fund or a duly appointed sub-custodian. The
Portfolio or Fund will enter into Repurchase Agreements only with banks and
broker-dealers that have been determined to be creditworthy by the Trust's Board
of Trustees under criteria established with the assistance of the Advisor or
Sierra Advisors. The seller under a Repurchase Agreement is required to maintain
the value of the obligations subject to the Repurchase Agreement at not less
than the repurchase price. Default by the seller would, however, expose the
Portfolio or the Fund to possible loss because of adverse market action or delay
in connection with the disposition of the underlying obligations. In addition,
if bankruptcy proceedings are commenced with respect to the seller of the
obligations, the Portfolio or Fund may be delayed or limited in its ability to
sell the collateral.
 
REVERSE REPURCHASE AGREEMENTS
 
   
All Portfolios and Funds except the Global Money Fund may engage in Reverse
Repurchase Agreements. Reverse Repurchase Agreements are the same as repurchase
agreements except that, in this instance, the Portfolio or Fund would assume the
role of seller/borrower in the transaction. The Portfolio or Fund will maintain
segregated accounts with the Trust's custodian consisting of U.S. Government
Securities, cash or money market instruments that at all times are in an amount
equal to their obligations under Reverse Repurchase Agreements. Reverse
Repurchase Agreements involve the risk that the market value of the securities
sold by a Portfolio or Fund may decline below the repurchase price of the
securities and, if the proceeds from the Reverse Repurchase Agreement are
invested in securities, that the market value of the securities bought may
decline below the repurchase price of the securities sold. Sierra Services or
each Fund's Sub-Advisor, acting under the supervision of the Board of Trustees,
    
 
                                      A-14
<PAGE>   48
 
reviews on an on-going basis the creditworthiness of the partners with which it
enters into Reverse Repurchase Agreements. Under the 1940 Act, Reverse
Repurchase Agreements may be considered borrowings by the seller. Whenever
borrowings by a Portfolio or Fund, including Reverse Repurchase Agreements,
exceed 5% of the value of the total assets of the Portfolio or Fund, the
Portfolio or Fund will not purchase any securities. See "Borrowing."
 
STRATEGIC TRANSACTIONS
 
Subject to the investment limitations and restrictions for each of the Funds as
stated elsewhere in the Prospectus and SAI of the Funds, each of the Funds
except the Global Money Fund may, but is not required to, utilize various
investment strategies as described in this Appendix to hedge various market
risks, to manage the effective maturity or duration of Fixed-Income Securities,
or to seek potentially higher returns. Utilizing these investment strategies,
the Fund may purchase and sell, to the extent not otherwise limited or
restricted for such Fund, exchange-listed and over-the-counter put and call
options on securities, equity and fixed-income indexes and other financial
instruments, purchase and sell financial futures contracts and options thereon,
enter into various Interest Rate Transactions such as swaps, caps, floors or
collars, and enter into various currency transactions such as currency forward
contracts, currency futures contracts, currency swaps or options on currencies
or currency futures (collectively, all the above are called "Strategic
Transactions").
 
Strategic Transactions may be used to attempt to protect against possible
changes in the market value of securities held in or to be purchased for the
Fund's portfolio resulting from securities markets or currency exchange rate
fluctuations, to protect the Fund's unrealized gains in the value of its
portfolio securities, to facilitate the sale of such securities for investment
purposes, to manage the effective maturity or duration of the Fund's portfolio,
or to establish a position in the derivatives markets as a temporary substitute
for purchasing or selling particular securities. Some Strategic Transactions may
also be used to seek potentially higher returns, although no more than 5% of the
Fund's assets will be used as the initial margin or purchase price of options
for Strategic Transactions entered into for purposes other than "bona fide
hedging" positions as defined in the regulations adopted by the Commodity
Futures Trading Commission. Any or all of these investment techniques may be
used at any time, as use of any Strategic Transaction is a function of numerous
variables including market conditions. The ability of the Fund to utilize these
Strategic Transactions successfully will depend on the Sub-Advisor's ability to
predict, which cannot be assured, pertinent market movements. The Fund will
comply with applicable regulatory requirements when utilizing Strategic
Transactions. Strategic Transactions involving financial futures and options
thereon will be purchased, sold or entered into only for bona fide hedging, risk
management or portfolio management purposes.
 
U.S. GOVERNMENT SECURITIES
 
U.S. Government Securities include direct obligations of the U.S. Treasury (such
as U.S. Treasury bills, notes and bonds) and obligations directly issued or
guaranteed by U.S. Government agencies or instrumentalities. Some obligations
issued or guaranteed by agencies or instrumentalities of the U.S. Government are
backed by the full faith and credit of the U.S. Government (such as GNMA Bonds),
others are backed only by the right of the issuer to borrow from the U.S.
Treasury (such as securities of Federal Home Loan Banks) and still others are
backed only by the credit of the instrumentality (such as FNMA and FHLMC Bonds).
 
WHEN-ISSUED SECURITIES AND DELAYED-DELIVERY TRANSACTIONS
 
   
In order to secure yields or prices deemed advantageous at the time, all Funds
except the Global Money Fund may purchase or sell securities on a when-issued or
a delayed-delivery basis. The Funds will enter into a when-issued transaction
for the purpose of acquiring portfolio securities and not for the purpose of
leverage. In such transactions, delivery of the securities occurs beyond the
normal settlement periods, but
    
 
                                      A-15
<PAGE>   49
 
   
no payment or delivery is made by, and no interest accrues to, the Funds prior
to the actual delivery or payment by the other party to the transaction. Due to
fluctuations in the value of securities purchased on a when-issued or a
delayed-delivery basis, the yields obtained on such securities may be higher or
lower than the yields available in the market on the dates when the investments
are actually delivered to the buyers. Similarly, the sale of securities for
delayed-delivery can involve the risk that the prices available in the market
when delivery is made may actually be higher than those obtained in the
transaction itself. The Funds will establish a segregated account with Boston
Safe consisting of cash, U.S. Government Securities or other liquid debt
obligations in an amount equal to the amount of its when-issued and
delayed-delivery commitments.

                        GENERAL INFORMATION AND HISTORY

        The Sierra Variable Trust (the "Trust") is an open-end management
investment company. Under the rules and regulations of the Securities and
Exchange Commission (the "SEC"), all mutual funds are required to furnish
prospective investors with certain information concerning the activities of the
investment company being considered for investment. Some of the information
required to be in this SAI is also included in the Trust's current
Prospectuses. To avoid unnecessary repetition, references are made to related
sections of the Prospectuses. In addition, the Prospectuses and this SAI omit
certain information about the Trust and its business that is contained in "Part
C" of the Trust's Registration Statement respecting the Trust and its Shares
filed with the SEC. Copies of the Registration Statement as filed, including
Part C, may be obtained from the SEC by paying the charges prescribed under its
rules and regulations.
   
        The Trust was organized under the laws of the Commonwealth of
Massachusetts on January 29, 1993. The Trust filed a registration statement
with the SEC registering itself as an open-end management investment company
offering diversified and nondiversified series under the Investment Company Act
of 1940, as amended (the "1940 Act"), and its shares under the Securities Act
of 1933, as amended. The Trust consists of the following 14 series: Global
Money Fund, Short Term High Quality Bond Fund, Short Term Global Government
Fund, U.S. Government Fund, Corporate Income Fund, Growth and Income Fund,
Growth Fund, Emerging Growth Fund and International Growth Fund (the "Funds");
and Income Portfolio, Value Portfolio, Balanced Portfolio, Growth Portfolio and
Capital Growth Portfolio (the "Portfolios"). Each of the Funds and Portfolios
has its own investment objective and policies. The Funds seek to achieve
their investment objectives by investing directly in investment securities,
while the Portfolios seek to meet their investment objectives by investing
primarily in the Funds.

COUNSEL AND AUDITOR

        Morgan, Lewis & Bockius LLP serves as counsel to the Trust and also
provides legal services to GW Securities, Sierra Advisors, Sierra
Administration and Sierra Services. Paul, Hastings, Janofsky & Walker serves as
counsel to the Trustees who are not "interested persons" of the Trust.

        Price Waterhouse LLP, independent accountants, located at 160 Federal
Street, Boston, Massachusetts 02110, serves as auditor of the Trust.

ORGANIZATION OF THE TRUST

        The Trust is organized as an unincorporated business trust under the
laws of the Commonwealth of Massachusetts pursuant to an Agreement and
Declaration of Trust dated January 27, 1993, as amended from time to time (the
"Declaration of Trust"). Certificates representing shares in the Trust are not
physically issued. The Trust's Custodian and the Trust's Transfer Agent
maintain a record of each shareholder's ownership of Trust shares. Shares do
not have cumulative voting rights, which means that holders of more than 50% of
the shares voting for the election of Trustees can elect all Trustees. Shares
are transferable but have no preemptive, conversion or subscription rights.
Shareholders generally vote by Fund, except with respect to the election of
Trustees and the selection of independent accountants.

        Under normal circumstances, there will be no meetings of shareholders
for the purpose of electing Trustees unless and until such time as less than a
majority of the Trustees holding office have been elected by shareholders, at
which time the Trustees then in office promptly will call a


                                      B-12
<PAGE>   63
shareholders' meeting for the election of Trustees. Under the 1940 Act,
shareholders of record of no less than two-thirds of the outstanding shares of
the Trust may remove a Trustee through a declaration in writing or by vote cast
in person or by proxy at a meeting called for that purpose. Under the
Declaration of Trust, the Trustees are required to call a meeting of
shareholders for the purpose of voting upon the question of removal of any such
Trustee when requested in writing to do so by the shareholders of record of not
less than 10% of the Trust's outstanding shares.

        The record owner of all the Trust's shares is Separate Account D of
AGL. However, Contract owners may be deemed to have beneficial ownership of
shares allocable to their Contracts. As of January 31, 1997, to the Trust's
knowledge, no Contract owner had shares allocable to Contracts equal to more
than five percent of any Fund.

        Massachusetts law provides that the shareholders, under certain
circumstances, could be held personally liable for the obligations of the
Trust. However, the Declaration of Trust disclaims shareholder liability for
acts or obligations of the Trust and requires that notice of such disclaimer be
given in each agreement, obligation or instrument entered into or executed by
the Trust or a Trustee. The Declaration of Trust provides for indemnification
from the Trust's property for all losses and expenses of any shareholder held
personally liable for the obligations of the Trust. Thus, the risk of a
shareholder incurring financial loss on account of shareholder liability is
limited to circumstances in which the Trust would be unable to meet its
obligations, a possibility that the Trust's management believes is remote. Upon
payment of any liability incurred by the Trust, the shareholder paying the
liability will be entitled to reimbursement from the general assets of the
Trust. The Trustees intend to conduct the operations of the Trust in such a way
so as to avoid, to the extent possible, ultimate liability of the shareholders
for liabilities of the Trust.

CERTAIN MATTERS RELATING TO J.P. MORGAN INVESTMENT MANAGEMENT INC. AND ITS
AFFILIATES

        J.P. Morgan Investment Management Inc. ("J.P. Management"), the
Sub-Advisor to the Global Money and Growth and Income Funds, and Morgan
Guaranty Trust Company of New York ("Morgan Guaranty") are both wholly owned
subsidiaries of J.P. Morgan & Co. Incorporated ("J.P. Morgan"). Through its
Corporate Finance Division, Morgan Guaranty has relationships as a bank of
deposit, as a lender, as a financial advisor and in other capacities, with a
significant number of United States corporations. Such corporate customers of
Morgan Guaranty obtain short-term funds to finance the operation of their
business generally through two sources: (i) short-term bank borrowings from
commercial banks such as Morgan Guaranty; and (ii) the issuance of commercial
paper of the type in which certain of the Funds may invest. Normally the
decision of a corporation as to which medium of short-term financing to utilize
will be influenced primarily by interest rate differentials between the
available sources of short-term funds. When interest rate differentials between
short-term bank borrowings and the commercial paper market narrow, the
Corporate Finance Division of Morgan Guaranty may be competing with the
commercial paper market to provide short-term funds to corporate borrowers.

        J.P. Morgan Securities Inc. ("J.P. Securities"), a wholly owned
subsidiary of J.P. Morgan, is a broker-dealer registered with the SEC and a
member of the National Association of



                                      B-13

<PAGE>   64
Securities Dealers, Inc. ("NASD"). J.P. Securities is active as a dealer in the
securities of the United States Government and an underwriter of and dealer in
securities of the United States Government agencies and money market
securities. To a limited extent, J.P. Securities also underwrites and deals in
commercial paper, certain mortgage-related securities, and consumer receivable
securities. J.P. Morgan Securities Limited ("J.P. Limited"), also a wholly
owned subsidiary of J.P. Morgan, underwrites, distributes and trades
international securities, including Eurobonds, commercial paper and foreign
government bonds. To the extent that the Global Money or Growth and Income
Funds are permitted to invest in such securities, the foregoing activities of
J.P. Securities and J.P. Limited may affect the manner in which J.P. Management
makes investments for such Funds and may affect such Funds' portfolios or the
markets for the securities in which such portfolios are invested. Such effects
would be primarily on: (1) the price of securities already held in the Global
Money or Growth and Income Funds or securities considered for purchase, which
are the same as or similar to issues underwritten or traded by J.P. Securities,
J.P. Limited, J.P. Morgan or Morgan Guaranty ("Morgan Affiliates"), and (2) the
supply of issues available for purchase by the Global Money or Growth and
Income Funds. Particularly, where the positions of Morgan Affiliates constitute
a large percentage of a given issue, the  price at which that issue is traded
may influence the price of securities of that issue or of similar securities in
the Global Money or Growth and Income Funds or securities being considered for
purchase. Also, since the Global Money and Growth and Income Funds will not
purchase directly from Morgan Affiliates, if the positions of Morgan Affiliates
in given issues is large, it may limit the selection of available securities in
that particular maturity, yield or price range.

        In addition, the Global Money and Growth and Income Funds will not
purchase securities of U.S. Government agencies during the existence of any
underwriting or selling group of which a Morgan Affiliate is a member except to
the extent permitted by law. Portfolio securities may not be purchased from or
sold to J.P. Management or any affiliated person (as defined in the 1940 Act)
of J.P. Management except as may be permitted by the Commission and subject to
the rules and regulations of the Comptroller of the Currency.

        J.P. Morgan issues commercial paper and long-term debt securities, and
Morgan Guaranty and some of its affiliates issue certificates of deposit and
create bankers' acceptances. The Global Money and Growth and Income Funds will
not invest in the commercial paper or other debt securities of J.P. Morgan or
in certificates of deposit or bankers' acceptances of Morgan Guaranty or such
affiliates. However, the activities of J.P. Morgan and Morgan Guaranty and any
of such affiliates in the market for such instruments might affect the
portfolios of such Funds or the market for such instruments.

        The limitations discussed in the preceding three paragraphs, in the
opinion of J.P. Management, will not significantly affect the ability of the
Global Money and Growth and Income Funds to pursue their respective investment
objectives. However, in the future in other circumstances, such Funds may be at
a disadvantage because of such limitations in comparison to other funds with
similar investment objectives which are not subject to such limitations. The
management of Sierra Advisors believes that the effects of such limitations are
more than offset by the experience and expertise J.P. Management provides to
such Funds.

                                      B-14
<PAGE>   65
        The Treasurer's Division of Morgan Guaranty manages Morgan Guaranty's
own investment portfolio, composed primarily of securities of the United States
Government and United States Government agencies. Such activities may affect
the portfolios of the Global Money and Growth and Income Funds or the markets
for the securities in which such portfolios invest. In acting for its fiduciary
accounts, including such Funds, J.P. Management will not discuss its investment
decisions or positions with the personnel of any Morgan Affiliates. J.P.
Management will not execute any transactions for such Funds with Morgan
Affiliates and will execute such transactions only with unaffiliated dealers.

        The commercial banking divisions of Morgan Guaranty or its affiliates
may have deposit, loan and other commercial banking relationships with issuers
of securities purchased by the Global Money and Growth and Income Funds,
including outstanding loans to such issuers that may be repaid in whole or in
part with the proceeds of securities purchased by such Funds in primary public
offerings. Such Funds will not purchase, except as may be permitted by
applicable law, securities in any primary public offering when the prospectus
discloses that the proceeds will be used to repay in whole or in part the loans
to such issuers. J.P. Management will not cause such Funds to make investments
for the direct purpose of benefitting other commercial interests of Morgan
Affiliates at the expense of such Funds. J.P. Management has advised such Funds
that, in making investment decisions, J.P. Management will not obtain or use
material inside information in the possession of any other division or
department of J.P. Management or from Morgan Affiliates. J.P. Management has
also advised such Funds that its investment personnel do not disclose any
material inside information in their possession regarding such Funds to any
other division or department of J.P. Management or Morgan Affiliates.

INVESTMENT OBJECTIVES AND POLICIES OF THE FUNDS AND PORTFOLIOS
   
        The Prospectuses discuss the investment objective or objectives of each
of the Funds and Portfolios and the policies to be employed to achieve such
objectives. This section contains supplemental information concerning the types
of securities and other instruments in which the Funds and Portfolios may
invest, the investment policies and portfolio strategies that the Funds and
Portfolios may utilize and certain risks attendant to such investments,
policies and strategies.
    
MONEY MARKET QUALITY AND MATURITY REQUIREMENTS

        The Global Money Fund will purchase only those instruments which meet
the applicable quality requirements described below. The Fund will not purchase
a security (other than a U.S. Government security) unless the security or the
issuer with respect to comparable securities (i) is rated by at least two
nationally recognized statistical rating organizations ("NRSROs") such as
Standard & Poor's Corporation ("S&P"), Moody's Investors Service, Inc.
("Moody's"), Duff & Phelps ("Duff") or Fitch Investors Service, Inc. ("Fitch"),
in one of the two highest rating categories for short-term debt securities,
(ii) is rated by the only NRSRO that has issued a rating in one of such NRSRO's
two highest categories for short-term debt, or (iii) if not so rated, the
security is determined to be of comparable quality. In addition, no more than
5% of the Fund's total assets will be invested in securities rated in the
second highest rating category by the

                                      B-15
<PAGE>   66
requisite NRSROs and, no more than 1% of the Fund's total assets will be
invested in the securities of any one such issuer. A description of the rating
systems of S&P, Moody's, Duff and Fitch is contained in the Appendix to this
SAI.

        At the time of investment, no security purchased by the Fund (except
securities subject to repurchase agreements and variable rate demand notes)
can have a maturity exceeding 397 days, and the Fund's average portfolio
maturity cannot exceed 90 days. The short average maturity of the portfolio
enhances the Fund's ability to maintain share prices at $1.00 which, in turn,
provides both stability of value and liquidity to shareholders. There can be
no assurances, however, that the Fund will be able to maintain net asset values
at $1.00 per share.

STRATEGIES AVAILABLE TO ALL FUNDS AND PORTFOLIOS

        BANK OBLIGATIONS. Domestic commercial banks organized under federal
law are supervised and examined by the Comptroller of the Currency and are
required to be members of the Federal Reserve System and to be insured by the
Federal Deposit Insurance Corporation (the "FDIC"). Domestic banks organized
under state law are supervised and examined by state banking authorities but
are members of the Federal Reserve System only if they elect to join. Most
state banks are insured by the FDIC (although such insurance may not be of
material benefit to a Fund or Portfolio, depending upon the principal amount of
certificates of deposit ("CDs") of each state bank held by a Fund or Portfolio)
and are subject to federal examination and to a substantial body of federal law
and regulation. As a result of federal and state laws and regulations,
domestic branches of domestic banks are, among other things, generally
required to maintain specific levels of reserves, and are subject to other
supervision and regulation designed to promote financial soundness.

        Obligations of foreign branches of U.S. banks and of foreign  branches
of foreign banks, such as CDs and time deposits ("TDs"), may be general
obligations of the parent bank in addition to the issuing branch, or may be
limited by the terms of a specific obligation and governmental regulation.
Obligations of foreign branches of U.S. banks and foreign banks are subject to
the risks associated with investing in foreign securities generally. Foreign
branches of U.S. banks and foreign branches of foreign banks are not necessarily
subject to the same or similar regulatory requirements that apply to U.S.
banks, such as mandatory reserve requirements, loan limitations, and
accounting, auditing and financial recordkeeping requirements. In addition,
less information may be publicly available about a foreign branch of a U.S.
bank or about a foreign bank than about a U.S. bank.

        Obligations of U.S. branches of foreign banks may be general
obligations of the parent bank in addition to the issuing branch, or may be
limited by the terms of a specific obligation and by federal and state
regulation as well as governmental action in the country in which the foreign
bank has its head office. A U.S. branch of a foreign bank may or may not be
subject to reserve requirements imposed by the Federal Reserve System or by the
state in which the branch is located if the branch is licensed in that state. In
addition, branches licensed by the Comptroller of the Currency and branches
licensed by certain states ("State Branches") may or may not be




                                      B-16
<PAGE>   67

required to (1) pledge to the regulator by depositing assets with a designated
bank within the state an amount of its assets equal to 5% of its total
liabilities, or (2) maintain assets within the state in an amount equal to a
specified percentage of the aggregate amount of liabilities of the foreign bank
payable at or through all of its agencies or branches within the state. The
deposits of State Branches may not necessarily be insured by the FDIC. In
addition, there may be less publicly available information about a U.S. branch
of a foreign bank than about a U.S. bank.

        In view of the foregoing factors associated with the purchase of CDs
and TDs issued by foreign banks and foreign branches of U.S. banks, a Fund's
Sub-Advisor or Portfolio's Advisor will carefully evaluate such investments on
a case-by-case basis.

        A Fund or Portfolio may purchase a CD, TD or bankers' acceptances
issued by a bank, savings and loan association or other banking institution
with less than $1 billion in assets (a "Small Issuer Bank Obligation") only
so long as the issuer is a member of the FDIC or supervised by the Office of
Thrift Supervision (the "OTS"), and so long as the principal amount of the
Small Issuer Bank Obligation is fully insured by the FDIC and is no more than
$100,000. Each of the Funds will at any one time hold only one Small Issuer
Bank Obligation from any one issuer.

        Savings and loan associations whose CDs, TDs and bankers' acceptances
may be purchased by the Funds and Portfolios are supervised by the OTS and
insured by the Savings Association Insurance Fund, which is administered by the
FDIC and is backed by the full faith and credit of the United States
Government. As a result, such savings and loan associations are subject to
regulation and examination.

        MORTGAGE-BACKED SECURITIES. The Mortgage-Backed Securities in which
all Funds may invest may be classified as governmental or government-related,
depending on the issuer or guarantor. Governmental mortgage-backed securities
are backed by the full faith and credit of the United States. GNMA, the
principal U.S. guarantor of such securities, is a wholly owned U.S. Government
corporation within the Department of Housing and Urban Development.
Government-related Mortgage-Backed Securities which are not backed by the full
faith and credit of the United States include those issued by FNMA and FHLMC.
FNMA is a government-sponsored corporation owned entirely by private
stockholders, which is subject to general regulation by the Secretary of
Housing and Urban Development. Pass-through securities issued by FNMA are
guaranteed as to timely payment of principal and interest by FNMA. FHLMC is a
corporate instrumentality of the United States, the stock of which is owned by
the Federal Home Loan Bank. Participation certificates representing interests
in mortgages from FHLMC's national portfolio are guaranteed as to the timely
payment of interest and ultimate collection of principal by FHLMC. In addition,
the U.S. Government Fund may invest in commercial mortgage-backed securities.
While these securities generally are structured with one or more types of
credit enhancement, they are issued by non-governmental entities and are not
guaranteed by governmental agency or instrumentality.

        Entities may create mortgage loan pools offering pass-through
investments in addition to those described above. The mortgages underlying
these securities may be alternative mortgage

                                      B-17
<PAGE>   68
instruments, that is, mortgage instruments in which principal or interest
payments may vary or terms to maturity may be shorter than previously
customary. As new types of mortgage-backed securities are developed and offered
to investors, the Funds and Portfolios will, consistent with their respective
investment objectives and policies, consider making investments in such new
types of securities.

        The average maturity of pass-through pools of mortgage-backed
securities varies with the maturities of the underlying mortgage instruments. In
addition, a pool's stated maturity may be shortened by unscheduled payments on
the underlying mortgages. Factors affecting mortgage prepayments include the
level of interest rates, general economic and social conditions, the location
of the mortgaged property and the age of the mortgage. Because prepayment
rates of individual mortgage pools vary widely, it is not possible to
accurately predict the average life of a particular pool. Common industry
practice, for example, is to assume that prepayments will result in a 7-to
9-year average life for pools of fixed-rate 30-year mortgages. Pools of
mortgages with other maturities of different characteristics will have varying
average life assumptions.

        RATINGS AS INVESTMENT CRITERIA. In general, the ratings of NRSROs, such
as Moody's, S&P, Duff and Fitch, represent the opinions of these agencies as to
the quality of securities which they rate. It should be emphasized, however,
that such ratings are relative and subjective and are not absolute standards of
quality. These ratings will be used by the Funds as initial criteria for the
selection of portfolio securities, but the Funds will also rely upon the
independent advice of their respective Sub-Advisors to evaluate potential
investments. The Appendix to this SAI contains further information concerning
the ratings of these services and their significance.

        To the extent that the rating given by a rating service for securities
may change as a result of changes in such organizations or their rating
systems, the Funds and Portfolios will attempt to use comparable ratings as
standards for its investments in accordance with the investment policies
contained in the Prospectuses and in this SAI.
   
        REPURCHASE AGREEMENTS. Each Fund and Portfolio may invest in
repurchase agreements without limitation as to amount. 
    
        U.S. GOVERNMENT SECURITIES. U.S. Government Securities include debt
obligations of varying maturities issued or guaranteed by the U.S. Government,
its agencies or instrumentalities. U.S. Government Securities include direct
obligations of the U.S. Treasury, and securities issued or guaranteed by the
Federal Housing Administration, Farmers Home Administration, Export-Import Bank
of the Untied States, Small Business Administration, Government National
Mortgage Association ("GNMA"), General Services Administration, Central Bank
for Cooperatives, Federal Farm Credit Banks, Federal Home Loan Banks, Federal
Home Loan Mortgage Corporation ("FHLMC"), Federal Intermediate Credit Banks,
Resolution Trust Corporation, Federal Land Banks, Federal National Mortgage
Association ("FNMA"), Maritime Administration, Tennessee Valley Authority,
District of Columbia Armory Board and Student Loan Marketing Association.
Direct obligations of the U.S. Treasury include a variety of securities that
differ in their interest rates, maturities and dates of issuance. Because the
U.S. Government is not obligated by law to provide support to an
instrumentality it sponsors, a Fund



                                      B-18
<PAGE>   69

or Portfolio will invest in obligations issued by such an instrumentality only
if the Fund's Sub-Advisor or Portfolio's Advisors determines that the credit
risk with respect to the instrumentality does not make its securities
unsuitable for investment by the Fund or Portfolio.
   
STRATEGIES AVAILABLE TO ALL FUNDS EXCEPT THE GLOBAL MONEY FUND AND TO THE
PORTFOLIOS
    
        FUTURES ACTIVITIES. The Portfolios and Funds may enter into futures
contracts and options on futures contracts that are traded on a U.S. exchange
or board of trade. These investments may be made by the Fund involved for the
purpose of hedging against changes in the value of its portfolio securities due
to anticipated changes in interest rates and market conditions. The ability of
a Fund to trade in futures contracts and options on futures contracts may be
materially limited by the requirement of the Internal Revenue Code of 1986, as
amended (the "Code"), applicable to a regulated investment company. See "Taxes"
below. In addition to the uses of futures described above, all Funds except
the Global Money Fund may use futures for certain other purposes. See
"Strategic Transactions."

        FUTURES CONTRACTS. An interest rate futures contract provides for the
future sale by one party and the purchase by the other party of a certain
amount of a specific financial instrument (debt security) at a specified price,
date, time and place. A bond index futures contract is an agreement pursuant to
which two parties agree to take or make delivery of an amount of cash equal to
the difference between the value of the index at the close of the last trading
day of the contract and the price at which the index contract was originally
written. No physical delivery of the underlying securities in the index is
made.

        The purpose of entering into a futures contract by a Fund is to protect
the Fund from fluctuations in the value of its securities caused by anticipated
changes in interest rates or market conditions without necessarily buying or
selling the securities. Of course, since the value of portfolio securities will
far exceed the value of the futures contracts entered into by a Fund, an
increase in the value of the futures contract would only mitigate - but not
totally offset - the decline in the value of the portfolio.

        No consideration is paid or received by a Fund upon entering into a
futures contract. Initially, a Fund would be required to deposit with the
broker an amount of cash or cash equivalents equal to approximately 1% to 10%
of the contract amount (this amount is subject to change by the board of trade
on which the contract is traded and members of such board of trade may charge a
higher amount). This amount is known as "initial margin" and is in its nature
the equivalent of a performance bond or good faith deposit on the contract,
which is returned to a Fund upon termination of the futures contract, assuming
all contractual obligations have been satisfied. Subsequent payments, known as
"variation margin," to and from the broker, will be made daily as the price of
the index or securities underlying the futures contract fluctuates, making the
long and short positions in the futures contract more or less valuable, a
process known as "marking-to-market." At any time prior to the expiration of a
futures contract, a Fund may elect to close the position by taking an opposite
position, which will operate to terminate the Fund's existing position in the
contract.

                                      B-19
<PAGE>   70
        There are several risks in connection with the use of futures contracts
as a hedging device.  Successful use of futures contracts by a Fund is subject
to the ability of the Fund's Sub-Advisor to correctly predict movements in the
direction of interest rates or changes in market conditions.  These predictions
involve skills and techniques that may be different from those involved in the
management of the portfolio being hedged.  In addition, there can be no
assurance that there will be a correlation between movements in the price of the
underlying index or securities and movements in the price of the securities
which are the subject of the hedge.  A decision of whether, when and how to
hedge involves the exercise of skill and judgment, and even a well-conceived
hedge may be unsuccessful for some degree because of market behavior or
unexpected trends in interest rates.

        Although the Funds intend to enter into futures contracts only if there
is an active market for such contracts, there is no assurance that an active
market will exist for the contracts at any particular time.  Most U.S. futures
exchanges and boards of trade limit the amount of fluctuation permitted in
futures contract prices during a single trading day.  Once the daily limit has
been reached in a particular contract, no trades may be made that day at a price
beyond that limit.  It is possible that futures contract prices would move to
the daily limit for several consecutive trading days with little or no trading,
thereby preventing prompt liquidation of futures positions and subjecting some
futures traders to substantial losses.  In such event, and in the event of
adverse price movements, a Fund would be required to make daily cash payments of
variation margin.  In such circumstances, an increase in the value of the
portion of the portfolio being hedged, if any, may partially or completely
offset losses on the futures contract.  However, as described above, there is no
guarantee that the price of the securities being hedged will, in fact, correlate
with the price movements in a futures contract and thus provide an offset to
losses on the futures contract.

        To ensure that transactions constitute bona fide hedges in instances
involving the purchase or sale or a futures contract, the Funds will be required
to either (i) segregate sufficient cash or other liquid assets to cover the
outstanding position or (ii) cover the futures contract by either owning the
instruments underlying the futures contract or by holding a portfolio of
securities with characteristics substantially similar to the underlying index or
stock index comprising the futures contract or by holding a separate option
permitting it to purchase or sell the same futures contract. Because of the
imperfect correlation between the movements in the price of underlying indexes
or stock indexes of various futures contracts and the movement of the price of
securities in the Funds' portfolios, the Funds will periodically make
adjustments to its index futures contracts positions to appropriately reflect
the relationship between the underlying portfolio and the indexes.  The Fund
will not maintain short positions in index or stock index futures contracts,
options written on index or stock index futures contracts and options written on
indexes or stock indexes, if in the aggregate, the value of these positions
exceeds the current market value of its securities portfolio plus or minus the
unrealized gain or loss on those positions, adjusted for the historical
volatility relationship between the portfolio and the index contracts.

        OPTIONS ON FUTURES CONTRACTS.  An option on a futures contract, as
contrasted with the direct investment in such a contract, gives the purchaser
the right, in return for the premium paid, to assume a position in the futures
contract at a specified exercise price at any time prior to the




                                      B-20


<PAGE>   71
expiration date of the option. Upon exercise of an option, the delivery of the
futures position by the writer of the option to the holder of the option will
be accompanied by delivery of the accumulated balance in the writer's futures
margin account, which represents the amount by which the market price of the
futures contract exceeds, in the case of a call, or is less than, in the case
of a put, the exercise price of the option on the futures contract. The
potential loss related to the purchase of an option on futures contracts is
limited to the premium paid for the option (plus transaction costs). Because
the price of the option to the purchaser is fixed at the point of sale, there
are no daily cash payments to reflect changes in the value of the underlying
contract; however, the value of the option does change daily and that change
would be reflected in the net asset value of the fund holding the options.

        The Funds may purchase and write put and call options on futures
contracts that are traded on a U.S. exchange or board of trade as a hedge
against changes in the value of its portfolio securities, and may enter into
closing transactions with respect to such options to terminate existing
positions. There is no guarantee that such closing transactions can be effected.

        There are several risks relating to options on futures contracts. The
ability to establish and close out positions on such options will be subject to
the existence of a liquid market. In addition, the purchase of put or call
options will be based upon predictions as to anticipated interest rate and
market trends by the Funds' Sub-Advisors, which could prove to be inaccurate.
Even if the expectations of the Sub-Advisors are correct, there may be an
imperfect correlation between the change in the value of the options and the
portfolio securities hedged. In addition to the uses of options described
above, all Funds except the Global Money Fund may use options for certain other
purposes. See "Strategic Transactions."

        OPTIONS ON SECURITIES. The Funds may write covered put options and
covered call options on securities, purchase put and call options on securities
and enter into closing transactions. The Funds may not write put options with
respect to more than 50% of their total assets.

        Options written by a Fund will normally have expiration dates between
one and nine months from the date written. The exercise price of the options
may be below, equal to or above the market values of the underlying securities
at the times the options are written. In the case of call options, these
exercise prices are referred to as "in-the-money," "at-the-money" and
"out-of-the-money," respectively. A Fund may write (1) in-the-money call
options when its Sub-Advisor expects that the price of the underlying security
will remain flat or decline moderately during the option period, (2)
at-the-money call options when its Sub-Advisor expects that the price of the
underlying security will remain flat or advance moderately during the option
period and (3) out-of-the-money call options when its Sub-Advisor expects that
the premiums received from writing the call option plus the appreciation in the
market price of the underlying security up to the exercise price will be
greater than the appreciation in the price of the underlying security alone. In
any of the preceding situations, if the market price of the underlying security
declines and the security is sold at this lower price, the amount of any
realized loss will be offset wholly or in part by the premium received.
Out-of-the-money, at-the-money and in-the-money put options (the reverse of
call options as to the relation of




                                      B-21


<PAGE>   72
exercise price to market price) may be utilized in the same market environments
as such call options described above.

        So long as the obligation of the Fund as the writer of an option
continues, the Fund may be assigned an exercise notice by the broker-dealer
through which the option was sold, requiring the Fund to deliver, in the case
of a call, or take delivery of, in the case of a put, the underlying security
against payment of the exercise price. This obligation terminates when the
option expires or the Fund effects a closing purchase transaction. The Fund can
no longer effect a closing purchase transaction with respect to an option once
it has been assigned an exercise notice. To secure its obligation to deliver
the underlying security when it writes a call option, or to pay for the
underlying security when it writes a put option, the Fund will be required to
deposit in escrow the underlying security or other assets in accordance with
the rules of the Options Clearing Corporation (the "OCC") and of the securities
exchange on which the option is written.

        An option may be closed out only when there exists a secondary market
for an option of the same series on a recognized securities exchange or in the
over-the-counter market (see "Over the Counter Options," below). In light of
this fact and current trading conditions, the Fund expects to purchase or write
call or put options issued by the OCC, as well at the following national
securities exchanges on which options are traded: The Chicago Board Options
Exchange (CBOE), The Board of Trade of the City of Chicago (CBT), American
Stock Exchange (AMEX), Philadelphia Exchange (PHLX), Pacific Stock Exchange
(PSE) and the New York Stock Exchange (NYSE).

        The Fund may realize a profit or loss upon entering into closing
transactions. In cases where the Fund has written an option, it will realize a
profit if the cost of the closing purchase transaction is less than the premium
received upon writing the original option, and will incur a loss if the cost of
the closing purchase transaction exceeds the premium received upon writing the
original option. Similarly, when the Fund has purchased an option and engages
in a closing sale transaction, the Fund will realize a profit or loss to the
extent that the amount received in the closing sale transaction is more or less
than the premium the Fund initially paid for the original option plus the
related transaction costs.

        To facilitate closing transactions, the Fund will generally purchase or
write only those options for which its Sub-Advisor believes there is an active
secondary market although there is no assurance that sufficient trading
interest to create a liquid secondary market on a securities exchange will
exist for any particular option or at any particular time, and for some options
no such secondary market may exist. A liquid secondary market in an option may
cease to exist for a variety of reasons. In the past, for example, higher than
anticipated trading activity or order flow, or other unforeseen events, have at
times rendered certain of the facilities of the OCC and the securities exchanges
inadequate and resulted in the institution of special procedures, such as
trading rotations, restrictions on certain types of orders or trading halts or
suspensions in one or more options. There can be no assurance that similar
events, or events that may otherwise interfere with the timely execution of
customers' orders, will not recur. In such events, it might not be possible to
effect closing transactions in particular options. If as a covered call option



                                      B-22

<PAGE>   73
writer the Fund is unable to effect a closing purchase transaction in a
secondary market, it will not be able to sell the underlying security until the
option expires or it delivers the underlying security upon exercise.

        Securities exchanges have established limitations governing the maximum
number of calls and puts of each class which may be held or written, or
exercised within certain time periods, by an investor or group of investors
acting in concert (regardless of whether the options are written on the same or
different securities exchanges or are held, written or exercised in one or more
accounts or through one or more brokers). It is possible that the particular
Fund and other clients of Sierra Advisors and its Sub-Advisors and certain of
their affiliates may be considered to be such a group. A securities exchange
may order the liquidation of positions found to be in violation of these limits
and it may impose certain other sanctions.

        In the case of options written by a Fund that are deemed covered by
virtue of the Fund's holding convertible or exchangeable preferred stock or
debt securities, the time required to convert or exchange and obtain physical
delivery of the underlying security with respect to which the Fund has written
options may exceed the time within which the Fund must make delivery in
accordance with an exercise notice. In these instances, the Fund may purchase or
temporarily borrow the underlying securities for purposes of physical delivery.
By so doing, the Fund will not bear any market risk, since the Fund will have
the absolute right to receive from the issuer of the underlying security an
equal number of shares to replace the borrowed stock. The Fund may however,
incur additional transaction costs or interest expenses in connection with any
such purchase or borrowing.

        Additional risks exist with respect to mortgage-backed U.S. Government
Securities for which the Fund may write covered call options. If a Fund writes
covered call options on a mortgage-backed security, the security that it holds
as cover may, because of scheduled amortization of unscheduled prepayments,
cease to be sufficient cover. The Fund will compensate by purchasing an
appropriate additional amount of mortgage-backed securities. In addition to the
uses of options described above, all Funds except the Global Money Fund may use
options for certain other purposes. See "Strategic Transactions."

        OPTIONS ON SECURITIES INDEXES. In addition to options on securities,
the Funds may also purchase and sell call and put options on securities
indexes. Such options give the holder the right to receive a cash settlement
during the term of the option based upon the difference between the exercise
price and the value of the index.

        Options on securities indexes entail risks in addition to the risks of
options on securities. Because exchange trading of options on securities
indexes is relatively new, the absence of a liquid secondary market to close
out an option position is more likely to occur, although the Fund generally
will purchase or write such an option only if its Sub-Advisor believes the
option can be closed out.

        Use of options on securities indexes also entails the risk that trading
in such options may be interrupted if trading in certain securities included in
the index is interrupted. The Fund will


                                      B-23
<PAGE>   74
not purchase or write such options unless its Sub-Advisor believes the market is
sufficiently developed for the risk of trading in such options to be no greater
than the risk of trading in options on securities.

        Price movements in the Fund's portfolio may not correlate precisely
with movements in the level of an index and, therefore, the use of options on
securities indexes cannot serve as a complete hedge. Because options on
securities indexes require settlement in cash, the Fund may be forced to
liquidate portfolio securities to meet settlement obligations. In addition to
the uses of options described above, all Funds except the Global Money Fund may
use options for certain other purposes. See "Strategic Transactions."

STRATEGIES AVAILABLE TO ALL FUNDS EXCEPT THE GLOBAL MONEY FUND

        OVER THE COUNTER OPTIONS. Over the Counter Options ("OTC Options") can
be closed out only by agreement with the primary dealer in the transaction, and
thus any OTC Options and their underlying securities or currencies are
considered illiquid. With OTC Options, terms such as expiration date, exercise
price and premium are agreed upon between the Fund and the transacting dealer,
without the intermediation of a third party such as the OCC. Any OTC Options
written by a Fund will be with a qualified dealer pursuant to an agreement
under which the Fund may repurchase the option at a formula price at which the
Fund would have the absolute right to repurchase an OTC Option it has sold. OTC
Options will be considered illiquid in an amount equal to the formula price,
less the amount by which the option is "in-the-money."

        REVERSE REPURCHASE AGREEMENTS. Under the 1940 Act, reverse repurchase
agreements may be considered borrowings by the seller; accordingly each of the
Funds will limit its investments in reverse repurchase agreements and other
borrowings to no more than 33 1/3% of its total assets. A Fund will not engage
in reverse repurchase transactions for the purpose of leverage.

        STRATEGIC TRANSACTIONS. No Fund currently intends to enter into
Strategic Transactions, excluding Strategic Transactions that are "covered" or
entered into for bona fide hedging purposes, that are in the aggregate principal
amount in excess of 15% of the Fund's net assets.

        Strategic Transactions have associated risks including possible default
by the other party to the transaction, illiquidity and, to the extent the
Sub-Advisor's view as to certain market movements is incorrect, losses greater
than if they had not been used. Use of put and call options, currency
transactions or options and futures transactions entails certain risks as
described herein and in the Appendix to the Prospectuses in sections relating
to such investment or instruments. Losses resulting from the use of Strategic
Transactions would reduce net asset value, and possibly income, and such losses
can be greater than if the Strategic Transactions had not been utilized.

        The Funds may enter into multiple transactions, including multiple
options transactions, multiple futures transactions, multiple foreign currency
transactions (including forward foreign currency exchange contracts) and any
combination of futures, options and foreign currency


                                      B-24
<PAGE>   75
transactions (each separately, a "component" transaction), instead of a single
transaction, as part of a single strategy when, in the opinion of the
Sub-Advisor, it is in the best interest of the Fund to do so. A combined
transaction may contain elements of risk that are present in each of its
component transactions.

        The use of Strategic Transactions for portfolio management purposes
involves special considerations and risks. Additional risks pertaining to
particular strategies that make up Strategic Transactions are described in
other sections to this SAI. Successful use of most Strategic Transactions
depends upon the Sub-Advisor's ability to predict movements of the overall
securities and interest rate markets, which requires different skills than
predicting changes in the prices of individual securities. There can be no
assurance that any particular strategy adopted will succeed. There may be
imperfect correlation, or even no correlation, between price movements of
Strategic Transactions and price movements of the related portfolio or currency
positions. Such a lack of correlation might occur due to factors unrelated to
the value of the related portfolio or currency positions, such as speculative
or other pressures on the markets in which Strategic Transactions are traded.
Strategic Transactions, if successful, can reduce risk of loss or enhance
income, by wholly or partially offsetting the negative effect of, or accurately
predicting, unfavorable price movements or currency fluctuations in the related
portfolio or currency position. However, Strategic Transactions can also reduce
the opportunity for gain by offsetting the positive effect of favorable price
movements in the positions. In addition, a Fund might be required to maintain
assets as "cover," maintain segregated accounts or make margin payments when it
takes positions in Strategic Transactions involving obligations to third
parties (i.e., Strategic Transactions other than purchased options). These
requirements might impair the Fund's ability to sell a portfolio security or
currency position or make an investment at a time when it would otherwise be
favorable to do so, or require that the Fund sell a portfolio security or
currency position at a disadvantageous time.

        WHEN-ISSUED SECURITIES AND DELAYED DELIVERY TRANSACTIONS. A segregated
account in the name of the Funds consisting of cash or liquid debt securities
equal to the amount of when-issued or delayed-delivery commitments will be
established at Boston Safe, the Trust's custodian. For the purpose of
determining the adequacy of the securities in the accounts, the deposited
securities will be valued at market or fair value. If the market or fair value
of the securities declines, additional cash or securities will be placed in the
account daily so that the value of the account will equal the amount of such
commitments by the Fund. On the settlement date, the Fund will meet its
obligations from then-available cash flow, the sale of securities held in the
segregated account, the sale of other securities or, although it would not
normally expect to do so, from the sale of securities purchased on a
when-issued or delayed-delivery basis themselves (which may have a greater or
lesser value than the Fund's payment obligations).

STRATEGIES AVAILABLE TO ALL FUNDS EXCEPT THE U.S. GOVERNMENT FUND

        AMERICAN DEPOSITARY RECEIPTS ("ADRs"), EUROPEAN DEPOSITARY RECEIPTS
("EDRs"), CONTINENTAL DEPOSITARY RECEIPTS ("CDRs") AND GLOBAL DEPOSITARY
RECEIPTS ("GDRs") ADRs are securities, typically issued by a U.S. financial
institution (a "depositary"), that evidence ownership interests in a security
or a pool of securities issued by a foreign issuer and deposited with the
depositary.  ADRs include American Depositary Shares and New York Shares.
EDRs, which are sometimes referred to as CDRs, are securities, typically issued
by a non-U.S. financial institution, that evidence ownership interests in a
security or a pool of securities issued by either a U.S. or foreign issuer.
GDRs are issued globally and evidence a similar ownership arrangement.
Generally, ADRs are designed for trading in the U.S. securities market, EDRs
are designed for trading in European securities market and GDRs are designed
for trading in non-U.S. securities markets.  ADRs, EDRs, CDRs and GDRs may be
available for investment through "sponsored" or "unsponsored" facilities.  A
sponsored facility is established jointly by the issuer of the security
underlying the receipt and a depositary, whereas an unsponsored facility may be
established by a depositary without participation by the issuer of the
receipt's underlying security.  Holders of an unsponsored depositary receipt
generally bear all the costs of the unsponsored facility.  The depositary of an
unsponsored facility frequently is under no obligation to distribute
shareholder communications received from the issuer of the deposited security
or to pass through to the holders of the receipts voting rights with respect to
the deposited securities.

        LENDING OF PORTFOLIO SECURITIES.  Each of the Funds will adhere to the
following conditions whenever its portfolio securities are loaned: (1) the Fund
must receive at least 100% cash collateral or equivalent securities from the
borrower; (2) the borrower must increase the collateral whenever the market
value of the securities rises above the level of the collateral; (3) the Fund
must be able to terminate the loan at any time; (4) the Fund must receive
reasonable interest on the loan, as well as any dividends, interest or other
distributions on the loaned securities and any increase in market value; (5) the
Fund may pay only reasonable custodian fees in connection with the loan; and
(6) voting rights on the loaned securities may pass to the borrower, provided
that if a material event adversely affecting the investment occurs, the Trust's
Board of Trustees must terminate the loan and regain the right to vote the
securities.  From time to time, the Funds may pay a part of the interest earned
from the investment of the collateral received for securities loaned to the
borrower and/or a third party that is unaffiliated with the Trust and that is
acting as a "finder."

STRATEGIES AVAILABLE TO ALL FUNDS EXCEPT GLOBAL MONEY AND U.S. GOVERNMENT FUNDS

         FOREIGN CURRENCY EXCHANGE TRANSACTIONS.   The Funds may engage in
currency exchange transactions to protect against uncertainty in the level of
future exchange rates.  The Funds' dealings in forward currency exchange
contracts will be limited to hedging involving either specific transactions or
portfolio positions.  Transaction hedging is the purchase or sale of forward
foreign currency with respect to specific receivables or payables of the Fund
generally

                                      B-26
<PAGE>   77
arising in connection with the purchase or sale of its portfolio securities.
Position hedging is the sale of forward foreign currency with respect to
portfolio security positions denominated or quoted in such foreign currency.  A
Fund may not position hedge with respect to a particular currency to an extent
greater than the aggregate market value (at the time of making such sale) of
the securities held in its portfolio denominated or quoted in or currently
convertible into that particular currency.

        If a Fund enters into a position hedging transaction, the Trust's
custodian or sub-custodian will, except in circumstances where segregated
accounts are not required by the 1940 Act and the rules adopted thereunder,
place cash, U.S. Government Securities or high-grade debt obligations in a
segregated account for the Fund in an amount at least equal to the value of the
Fund's total assets committed to the consummation of the forward contract.  For
each forward foreign currency exchange contract that is used to hedge a
securities position denominated in a foreign currency, but for which the
hedging position no longer provides, in the opinion of the Sub-Advisor or the
Advisor, sufficient protection to consider the contract to be a hedge, the
Fund maintains with its custodian a segregated account of cash, U.S.
Government Securities or other liquid assets in an amount at least equal to
the portion of the contract that is no longer sufficiently covered by such
hedge.  If the value of the securities placed in the segregated account
declines, additional cash or securities will be placed in the account so that
the value of the account will equal the amount of the Fund's unhedged exposure
(in the case of securities denominated in a foreign currency) or commitment
with respect to the contract.  Hedging transactions may be made from any
foreign currency into U.S. dollars or into other appropriate currencies.

         At or before the maturity of a forward contract, a Fund may either sell
a portfolio security and make delivery of the currency, or retain the security
and offset its contractual obligation to deliver the currency by purchasing a
second contract pursuant to which the Fund will obtain, on the same maturity
date, the amount of the currency that it is obligated to deliver.  If the Fund
retains the portfolio security and engages in an offsetting transaction, the
Fund, at the time of execution of the offsetting transaction, will incur a gain
or a loss to the extent that movement has occurred in forward contract prices.
Should forward prices decline during the period between the Fund's entering into
a forward contract for the sale of currency and the date it enters into an
offsetting contract for the purchase of the currency, the Fund will realize a
gain to the extent the price of the currency it has agreed to sell exceeds the
price of the currency it has agreed to purchase.  Should forward prices
increase, the Fund will suffer a loss to the extent the price of the currency it
has agreed to purchase exceeds the price of the currency it has agreed to sell.

        The cost to a Fund of engaging in currency transactions varies with
factors such as the currency involved, the length of the contract period and
the prevailing market conditions.  Because transactions in currency exchange
are usually conducted on a principal basis, no fees or commissions are
involved.  The use of forward currency contracts does not eliminate
fluctuations in the underlying prices of the securities, but it does establish
a rate of exchange that can be achieved in the future.  In addition, forward
currency contracts may limit the risk of loss due to a decline in the value of
the hedged currency increase.

<PAGE>   78
        If a devaluation of a currency is generally anticipated, a Fund may not
be able to contract to sell the currency at a price above the devaluation level
it anticipates.

        The Funds, in addition, may combine forward currency exchange contracts
with investments in securities denominated in other currencies in an attempt to
create a combined investment position, the overall performance of which will
be similar to that of a security denominated in a Fund's underlying currency.
For instance, a Fund could purchase a U.S. dollar-denominated security and at
the same time enter into a forward currency exchange contract to exchange U.S.
dollars for its underlying currency at a future date.  By matching the amount
of U.S. dollars to be exchanged with the anticipated value of the U.S.
dollar-denominated security, the Fund may be able to "lock in" the foreign
currency value of the security and adopt a synthetic investment position
whereby the Fund's overall investment return from the combined position is
similar to the return from purchasing a foreign currency-denominated instrument.

        There is a risk in adopting a synthetic investment position.  It is
impossible to forecast with absolute precision what the market value of a
particular security will be at any given time.  If the value of a security
denominated in the U.S. dollar or other foreign currency is not exactly matched
with a Fund's obligation under a forward currency exchange contract on the date
of maturity, the Fund may be exposed to some risk of loss from fluctuations in
that currency.  Although each Fund's Sub-Advisor will attempt to hold such
mismatching to a minimum, there can be no assurance that the Fund's Sub-Advisor
will be able to do so.

         Although the foreign currency market is not believed to be necessarily
more volatile than the market in other commodities, there is less protection
against defaults in the forward trading to currencies than there is in trading
such currencies on an exchange because such forward contracts are not guaranteed
by an exchange or clearing house.  The CFTC has indicated that it may assert
jurisdiction over forward contracts in foreign currencies and attempt to
prohibit certain entities from engaging in such transactions.  In the event that
such prohibition included the Fund, it would cease trading such contracts.
Cessation of trading might adversely affect the performance of a Fund.

        In addition to the uses of foreign currency exchange transactions
described above, all Funds except the Global Money and the U.S. Government
Funds may use foreign currency exchange transactions for certain other
purposes.  See "Strategic Transactions."

        OPTIONS ON FOREIGN CURRENCIES.  The Funds may purchase and write put
and call options on foreign currencies for the purpose of hedging against
declines in the U.S. dollar value of foreign currency-denominated portfolio
securities and against increases in the U.S. dollar cost of such securities to
be acquired.  Such hedging includes cross hedging and proxy hedging where the
options to buy or sell currencies involve other currencies besides the U.S.
dollar.  As one example, a decline in the U.S. dollar value of a foreign
currency in which securities are denominated will reduce the U.S. dollar value
of the securities, even if their value in the foreign currency remains
constant.  To protect against diminutions in the value of securities held by a
Fund in a particular foreign currency, the Fund may purchase put options on the
foreign currency.  If the value of the currency does decline, the Fund will
have the right to sell the



                                      B-28

<PAGE>   79
currency for a fixed amount in U.S. dollars and will thereby offset, in whole
or in part, the adverse effect on its portfolio that otherwise would have
resulted. When an increase in the U.S. dollar value of a currency in which
securities to be acquired are denominated is projected, thereby increasing the
cost of the securities, the Fund conversely may purchase call options on the
currency. The purchase of such options could offset, at least partially, the
effects of the adverse movements in exchange rates. As in the case of other
types of options, however, the benefit to the Fund deriving from purchases of
foreign currency options will be reduced by the amount of the premium and
related transaction costs. In addition, if currency exchange rates do not move
in the direction, or to the extent anticipated, the Fund could sustain losses
on transactions in foreign currency options that would require it to forego a
portion or all of the benefits of advantageous changes in the rates.

        The Fund may also write covered call options on foreign currencies for
the types of hedging purposes described above. As one example, when a Fund
anticipates a decline in the U.S. dollar value of foreign currency-denominated
securities due to adverse fluctuations in exchange rates, it could, instead of
purchasing a put option, write a covered call option on the relevant currency.
If the expected decline occurs, the option will most likely not be exercised,
and the diminution in value of portfolio securities will be offset by the
amount of the premium received. As in the case of other types of options,
however, the writing of a foreign currency option will constitute only a
partial hedge up to the amount of the premium, and only if rates move in the
expected direction. If this does not occur, the option may be exercised and the
Fund would be required to purchase or sell the underlying currency at a loss
that may not be offset by the amount of the premium. Through the writing of
options on foreign currencies, the Fund may also be required to forego all or a
portion of the benefits that might otherwise have been obtained from favorable
movements in exchange rates.

        A call option written on a foreign currency by a Fund is "covered" if
the Fund owns the underlying foreign currency covered by the call or has an
absolute and immediate right to acquire the foreign currency without additional
cash consideration (or for additional cash consideration held in a segregated
account by Boston Safe, or by a designated sub-custodian) upon conversion or
exchange of other foreign currency held by the Fund. A call option also is
covered if the Fund has a call on the same foreign currency and in the same
principal amount as the call written when the exercise price of the call held
(1) is equal to or less than the exercise price of the call written or (2) is
greater than the exercise price of the call written if the difference is
maintained by the Fund in cash, U.S. Government Securities and other liquid
assets in a segregated account with Boston Safe or with a designated
sub-custodian.

        Options on foreign currencies traded on national securities exchanges
are within the jurisdiction of the SEC, as are other securities traded on those
exchanges. As a result, many of the protections provided to traders on
organized exchanges will be available with respect to those transactions. In
particular, all foreign currency option positions entered into on a national
securities exchange are cleared and guaranteed by the OCC, thereby reducing the
risk of counterparty default. Further, a liquid secondary market in options
traded on a national securities exchange may exist, potentially permitting the
Fund to liquidate open positions at a profit prior to their exercise or
expiration, or to limit losses in the event of adverse market movements.


                                      B-29

<PAGE>   80
        The purchase and sale of exchange-traded foreign currency options are
subject to the risks of the availability of a liquid secondary market described
above, as well as the risks regarding adverse market movements, margining of
options written, the nature of the foreign currency market, possible
intervention by governmental authorities and the effects of other political and
economic events. In addition, exercise and settlement of exchange-traded foreign
currency options must be made exclusively through the OCC, which has established
banking relationships in applicable foreign countries for this purpose. As a
result, the OCC may, if it determines that foreign governmental restrictions or
taxes would prevent the orderly settlement of foreign currency option exercises,
or would result in undue burdens on the OCC or its clearing member, impose
special procedures on exercise and settlement, such as technical changes in the
mechanics of delivery of currency, the fixing of dollar settlement prices or
prohibitions on exercise. For a discussion of the risks involved in OTC Options
in foreign currency, see "Over the Counter Options" above.

        In addition to the uses of options on foreign currencies described
above, all Funds except the Global Money and U.S. Government Funds may use
options on foreign currencies for certain other purposes. See "Strategic
Transactions."

STRATEGY AVAILABLE TO SHORT TERM GLOBAL GOVERNMENT, GROWTH AND EMERGING GROWTH
FUNDS

        LOWER-RATED SECURITIES. The Short Term Global Government Fund may
invest up to 10% and the Growth and Emerging Growth Funds up to 35% of its
total assets in non-investment grade securities (rated Ba and lower by Moody's
or BB and lower by Standard & Poor's) or unrated securities. Such securities
carry a high degree of risk (including the possibility of default or bankruptcy
of the issuer of such securities), generally involve greater volatility of
price and risk of principal and income, and may be less liquid, than securities
in the higher rating categories and are considered speculative. See the
Appendix to this SAI for a more complete description of the ratings assigned by
ratings organizations and their respective characteristics.

        The recent economic downturn disrupted the high yield market and
impaired the ability of issuers to repay principal and interest. Also, an
increase in interest rates could further adversely affect the value of such
obligations held by the Fund. Prices and yields of high yield securities will
fluctuate over time and may affect the Fund's net asset value. In addition,
investments in high yield zero coupon or pay-in-kind bonds, rather than
income-bearing high yield securities, may be more speculative and may be
subject to greater fluctuations in value due to changes in interest rates.

        The trading market for high yield securities may be thin to the extent
that there is no established retail secondary market or because of a decline in
the value of such securities. A thin trading market may limit the ability of
the Trustees to accurately value high yield securities in the Fund's portfolio
and to dispose of those securities. Adverse publicity and investor perceptions
may decrease the value and liquidity of high yield securities. These securities
may also involve special registration responsibilities, liabilities and costs.


                                      B-30

<PAGE>   81
        Credit quality in the high yield securities market can change suddenly
and unexpectedly, and even recently-issued credit ratings may not fully reflect
the actual risks posed by a particular high yield security. For these reasons,
it is the policy of each of these Fund's Sub-Advisors not to rely exclusively
on ratings issued by established credit rating agencies, but to supplement such
ratings with its own independent and ongoing review of credit quality. The
achievement of the Fund's investment objectives by investment in such
securities may be more dependent on its Sub-Advisor's credit analysis than is
the case for higher quality bonds. Should the rating of a portfolio security be
downgraded, the Fund's Sub-Advisor will determine whether it is in the best
interest of the Fund to retain the security.

        Prices for below investment grade securities may be affected by
legislative and regulatory developments. For example, new federal rules require
savings and loan institutions to gradually reduce their holdings of this type
of security. Also, Congress from time to time has considered legislation which
would restrict or eliminate the corporate tax deduction for interest payments
on these securities and would regulate corporate restructurings. Such
legislation may significantly depress the prices of outstanding securities of
this type.

STRATEGY AVAILABLE TO GROWTH, EMERGING GROWTH AND INTERNATIONAL GROWTH FUNDS

        SECURITIES IN DEVELOPING COUNTRIES. Although most of the investments of
the Growth Fund, Emerging Growth Fund and International Growth Fund are made in
securities of companies in (or governments of) developed countries, up to 5% of
the total assets of the Growth Fund and Emerging Growth Fund and up to 30% of
the total assets of the International Growth Fund may be invested in securities
of companies in (or governments of) developing or emerging countries (sometimes
referred to as "emerging markets") as well. A developing or emerging country is
generally considered to be a country that is in the initial stages of its
industrialization cycle. Investing in the equity and fixed-income markets of
developing or emerging countries involves exposure to economic structures that
are generally less diverse and mature, and to political systems that can be
expected to have less stability than those of developed countries. Historical
experience indicates that the markets of developing or emerging countries have
been more volatile than the markets of the more mature economies of developed
countries; however, such markets often have provided higher rates of return to
investors.

                   INVESTMENT RESTRICTIONS OF THE PORTFOLIOS

        The following investment restrictions have been adopted by the Trust
with respect to the Portfolios as fundamental policies. A fundamental policy
affecting a particular Portfolio may not be changed without the vote of a
majority of the outstanding shares of the affected Portfolio. Majority is
defined in the 1940 Act as the lesser of (a) 67% or more of the shares present
at a shareholder meeting, if the holders of more than 50% of the outstanding
shares of the Trust are present or represented by proxy, or (b) more than 50%
of the outstanding shares. Each Portfolio will not;

1.      Purchase or sell physical commodities unless acquired as a result of
        ownership of securities or other instruments (except this shall not
        prevent the Fund from purchasing or


                                      B-31

<PAGE>   82
        selling options or futures contracts or from investing in securities or
        other instruments backed by physical commodities);

2.      Purchase or sell real estate including limited partnership interests,
        although it may purchase and sell securities of companies that deal in
        real estate and may purchase and sell securities that are secured by
        interests in real estate;

3.      Make loans to any person, except loans of portfolio securities to the
        extent that no more than 33 1/3% of its total assets would be lent to
        other parties, but this limitation does not apply to purchases of debt
        securities or repurchase agreements;

4.      (i) Purchase more than 10% of any class of the outstanding voting
        securities of any issuer (except other investment companies as defined
        in the 1940 Act) and (ii) purchase securities of an issuer (except
        obligations of the U.S. Government and its agencies and
        instrumentalities and securities of other investment companies as
        defined in the 1940 Act) if as a result, with respect to 75% of its
        total assets, more than 5% of the Portfolio's total assets, at market
        value, would be invested in the securities of such issuer;

5.      Issue senior securities (as defined in the 1940 Act) except as permitted
        by rule, regulation or order of the SEC;

6.      Will not borrow, except from banks for temporary or emergency (not
        leveraging) purposes including the meeting of redemption requests that
        might otherwise require the untimely disposition of securities in an
        aggregate amount not exceeding 30% of the value of the Portfolio's total
        assets (including the amount borrowed) valued at market less liabilities
        (not including the amount borrowed) at the time the borrowing is made;
        and whenever borrowings by a Portfolio, including reverse repurchase
        agreements, exceed 5% of the value of a Portfolio's total assets, the
        Portfolio will not purchase any securities;

7.      Underwrite securities issued by others, except to the extent that the
        Portfolio may be considered an underwriter within the meaning of the
        1933 Act in the disposition of restricted securities; and

8.      Write or acquire options or interests in oil, gas or other mineral
        exploration or development programs.

        In addition, each Portfolio has adopted non-fundamental investment
limitations as stated below and in its prospectus. Such limitations may be
changed without shareholder approval. Each Portfolio will not:
   
    

                                      B-32
<PAGE>   83
   
1.      Pledge, mortgage, or hypothecate any of its assets except to secure
        borrowings permitted by the Portfolio's fundamental limitation on
        borrowing;

2.      Invest for the purpose of exercising control over management of any
        company;

3.      Invest its assets in securities of any investment company, except (i) by
        purchase in the open market involving only customary brokers'
        commissions; (ii) in connection with mergers, acquisitions of assets or
        consolidations; (iii) as permitted by SEC exemptive order; or (iv) as
        otherwise permitted by the 1940 Act;

4.      Purchase warrants if, by reason of such purchase, more than 5% of the
        value of the Portfolio's net assets (taken at market value) would be
        invested in warrants, valued at the lower of cost or market; included
        within this amount, but not to exceed 2% of the value of the Fund's net
        assets, may be warrants that are not listed on a recognized stock
        exchange;

5.      Purchase or hold illiquid securities, which are securities that cannot
        be disposed of for their approximate market value in seven days or less
        (which terms include repurchase agreements and time deposits maturing in
        more than seven days) if, in the aggregate, more than 15% of its net
        assets would be invested in illiquid securities;

6.      Purchase securities on margin, except that a Portfolio may obtain any
        short-term credits necessary for the clearance of purchases and sales of
        securities. For purposes of this restriction, the deposit or payment of
        initial or variation margin in connection with futures contracts or
        related options will not be deemed to be a purchase of securities on
        margin; and

7.      Purchase or hold lower rated bonds ("junk bonds"), directly or
        indirectly, if, in the aggregate, 35% or more of its net assets would be
        invested, directly or indirectly, in junk bonds.
    
                      INVESTMENT RESTRICTIONS OF THE FUNDS
   
        The investment restrictions number 1 through 15 below have been adopted
by the Trust with respect to the Funds as fundamental policies. A fundamental
policy may not be changed without the vote of a majority of the outstanding
voting securities of the Trust, as defined in the 1940 Act. Investment
restrictions 16 through 19 may be changed by vote of a majority of the Trust's
Board of Trustees at any time.
    

                                      B-33
<PAGE>   84
        The investment policies adopted by the Trust prohibit a Fund from:

1.      Purchasing the securities of any issuer (other than U.S. Government
        Securities) if as a result more than 5% of the value of the Fund's total
        assets would be invested in the securities of the issuer (the "5%
        Limitation"), except that up to 25% of the value of the Fund's total
        assets may be invested without regard to the 5% Limitation; provided
        that this restriction shall not apply to the Short Term Global
        Government Fund; and provided further that the entire investment
        portfolio of the Global Money Fund is subject to the 5% Limitation.
        However, the Global Money Fund will be able to invest more than 5% of
        its total assets in the securities of a single issuer for a period of up
        to three Business Days after the purchase thereof; provided that the
        Fund may not hold more than one such investment at any time.

2.      Purchasing more than 10% of the securities of any class of any one
        issuer; provided that this limitation shall not apply to investments in
        U.S. Government Securities; provided further that this restriction shall
        not apply to the Short Term Global Government and Growth Funds; and
        provided further that the Growth Fund shall not own more than 10% of the
        outstanding voting securities of a single issuer.

3.      Purchasing securities on margin, except that the Fund may obtain any
        short-term credits necessary for the clearance of purchases and sales of
        securities. For purposes of this restriction, the deposit or payment of
        initial or variation margin in connection with futures contracts or
        related options will not be deemed to be a purchase of securities on
        margin.

4.      Making short sales of securities or maintaining a short position;
        provided that this restriction shall not apply to the Short Term Global
        Government, Growth and International Growth Funds.

5.      Borrowing money, except that (a) the Fund may (i) enter into Reverse
        Repurchase Agreements or (ii) borrow from banks for temporary (not
        leveraging) purposes, including the meeting of redemption requests that
        might otherwise require the untimely disposition of securities or
        pending settlement of securities transactions or for emergency or
        extraordinary purposes in an aggregate amount not exceeding 30% of the
        value of the Fund's total assets (including the amount borrowed) valued
        at market less liabilities (not including the amount borrowed) at the
        time the borrowing is made, (b) all of the Funds except the Global Money
        Fund may enter into (i) futures contracts, and (ii) dollar roll

PORTFOLIO TURNOVER
   
        Portfolio turnover considerations for the Portfolios are addressed in
the Trust's prospectus.
    
        The Global Money Fund, a money market fund, attempts to increase yields
by trading to take advantage of short-term market variations, which results in
high portfolio turnover. Because purchases and sales of money market instruments
are usually effected as principal transactions, this policy does not result in
high brokerage commissions to the Fund. The Growth and Income, Growth,
Emerging Growth and International Growth Funds (together, the "Equity Funds")
and the Short Term High Quality Bond, the Short Term Global Government, the
U.S. Government and the Corporate Income Funds (collectively, the "Bond Funds")
do not intend to seek profits



                                      B-36
<PAGE>   87
through short-term trading.  Nevertheless, the Funds will not consider
portfolio turnover rate a limiting factor in making investment decisions.

        Under certain market conditions, the Equity Funds and the Bond Funds
may experience increased portfolio turnover as a result of such Fund's options
activities.  For instance, the exercise of a substantial number of options
written by the Fund (due to appreciation of the underlying security in the case
of call options or depreciation of the underlying security in the case of put
options) could result in a turnover rate in excess of 100%.  A portfolio
turnover rate of 100% would occur if all of the Fund's securities that are
included in the computation of turnover were replaced once during a period of
one year.  The portfolio turnover rate is calculated by dividing the lesser of
purchases or sales of portfolio securities for the year by the monthly average
value of portfolio securities.  Securities with remaining maturities of one
year or less at the date of acquisition are excluded from the calculation.

        Certain other practices that may be employed by the Funds could result
in high portfolio turnover.  For example, portfolio securities may be sold in
anticipation of a rise in interest rates (market decline) or purchased in
anticipation of a decline in interest rates (market rise) and later sold.  In
addition, a security may be sold and another of comparable quality purchased at
approximately the same time to take advantage of what a Fund's Sub-Advisor
believes to be a temporary disparity in the normal yield relationship between
the two securities.  These yield disparities may occur for reasons not
directly related to the investment quality of particular issues or the general
movement of interest rates, such as changes in the overall demand for, or
supply of, various types of securities.

PORTFOLIO TRANSACTIONS

        Purchases and sales of Fund shares by a Portfolio are effected directly
through the Trust's distributor, Sierra Services.  In addition, all decisions
to buy and sell securities, including Fund shares, are made by Sierra Services,
subject to the overall review of the Trustees.

        Most of the purchases and sales of securities for a Fund, whether
transacted on a securities exchange or over-the-counter, will be effected in
the primary trading market for the securities.  Decisions to buy and sell
securities for a Fund are made by its Sub-Advisor, which also is responsible
for placing these transactions, subject to the overall review of the Trust's
Trustees.  Although investment decisions for each Fund are made independently
from those of the other accounts managed by its Sub-Advisor, those other
accounts may make investments of the same type as the Fund.  When a Fund and one
or more other accounts managed by its Sub-Advisor are prepared to invest in, or
desire to dispose of, the same security, available investments or opportunities
for sales will be allocated in a manner believed by the Sub-Advisor to be
equitable to each.  In some cases, this procedure may adversely affect the price
paid or received by a Fund or the size of the position obtained or disposed of
by the Fund.  In other cases, however, it is believed that the coordination and
the ability to participate in volume transactions will be to the benefit of the
Fund.



                                      B-37
<PAGE>   88
        Transactions on U.S. exchanges involve the payment of negotiated
brokerage commissions.  With respect to exchanges on which commissions are
negotiated, the cost of transactions may vary among different brokers.  There
is generally no stated commission in the case of securities traded in the
over-the-counter markets, but the prices of those securities include
undisclosed commissions or concessions, and the prices at which securities are
purchased from and sold to dealers include a dealer's mark-up or mark-down.
U.S. Government Securities may be purchased directly from the U.S. Treasury or
from the issuing agency or instrumentality.

        In selecting brokers or dealers to execute portfolio transactions on
behalf of a Fund, the Fund's Sub-Advisor seeks the best overall terms
available.  In assessing the best overall terms available for any transaction,
each Sub-Advisor will consider the factors the Sub-Advisor deems relevant,
including the breadth of the market in the security, the price of the security,
the financial condition and execution capability of the broker or dealer and
the reasonableness of the commission, if any, for the specific transaction and
on a continuing basis.  In addition, each advisory agreement between the Trust
and Sierra Advisors and each sub-advisory agreement between Sierra Advisors and
a Sub-Advisor authorizes the Advisor or Sub-Advisor, in selecting brokers or
dealers to execute a particular transaction and in evaluating the best overall
terms available, to consider the brokerage and research services (as those
terms are defined in Section 28(e) of the Securities Exchange Act of 1934, as
amended) provided to the Trust, the other Funds and/or other accounts over
which the Sub-Advisors or its affiliates exercise investment discretion.  The
fees under the advisory agreements between the Trust and the Advisor are not
reduced by reason of the receipt by the Advisor or Sub-Advisors of brokerage
and research services.  The Trust's Trustees will periodically review the
commissions paid by the Funds to determine if the commissions paid over
representative periods of time were reasonable in relation to the benefits
received by the Trust.

   
        To the extent consistent with applicable provisions of the 1940 Act and
the rules and exemptions adopted by the Commission thereunder, the Trust's Board
of Trustees has determined that portfolio transactions for a Fund may be
executed through GW Securities or any other affiliated broker, including J.P.
Securities or J.P. Limited (which are affiliates of J.P. Management, the
Sub-Advisor of the Global Money and Growth and Income Funds), if, in the
judgment of the Fund's Sub-Advisor, the use of GW Securities or an affiliated
broker is likely to result in price and execution at least as favorable as those
of other qualified broker-dealers, and if, in the transaction, GW Securities or
such other affiliated broker charges the Fund a rate consistent with those
charged for comparable transactions in comparable accounts of the broker's most
favored unaffiliated clients.  Over-the-counter purchases and sales are
transacted directly with principal market makers except in those cases in which
better prices and executions may be obtained elsewhere.  For the three fiscal
years ended December 31, 1994, December 31, 1995 and December 31, 1996, the
Trust paid brokerage commissions of approximately $__________, $0 and $3,086,
respectively, to J.P. Morgan. For the fiscal year ended December 31, 1994,
December 31, 1995 and December 31, 1996, commissions paid to J.P. Morgan
represented approximately ____%, 0% and 51%, respectively, of the total amount
of brokerage commissions paid in such period and which were paid on transactions
that represented ____%, 0% and 47% respectively, of the aggregate dollar amount
of transactions that incurred commissions paid by the Trust during such period.
For the three fiscal years ended December 31, 1994, December 31, 1995 and
December 31, 1996, the Trust paid brokerage commissions of approximately
$______, $0 and $2,945, respectively, to Donaldson, Lufkin & Jenrette.  For the
fiscal years ended December 31, 1994, December 31, 1995 and December 31, 1996,
commissions paid to Donaldson, Lufkin & Jenrette represented approximately __%,
0% and 49%, respectively, of the total amount of brokerage commissions paid in
such period and which were paid on transactions that represented __%, 0% and
53%, respectively, of the aggregate dollar amount of transactions that incurred
commissions paid by the Trust during such period.

        The Trust is required to identify any securities of its "regular
brokers or dealers" (as such term is defined in the 1940 Act) which the Trust
has acquired during its most recent fiscal year. As of December 31, 1996, the
Growth and Income Fund held common stock of Dean Witter, Discover & Company
valued at $669,125.

                         PURCHASE AND PRICING OF SHARES

        Shares in the Portfolios and Funds are purchased and redeemed and net
asset value is calculated in the manner described in the Prospectuses.

REDEMPTIONS

        The right of redemption of shares of a Portfolio or Fund may be
suspended or the date of payment postponed (1) for any periods during which the
NYSE is closed (other than for customary weekend and holiday closings), (2)
when trading in the markets the Fund (or underlying Fund of a Portfolio)
normally utilizes is restricted, or an emergency, as defined by the rules and
regulations of the SEC, exists making disposal of the Fund's investments or
determination of its net asset value not reasonably practicable or (3) for such
other periods as the SEC by order may permit for protection of the Fund's
shareholders.

        DISTRIBUTIONS IN KIND.  If the Board of Trustees determines that it
would be detrimental to the best interests of the shareholders of a Portfolio
or Fund to make a redemption payment wholly in cash, the Trust may pay any
portion of a redemption by distribution in kind of portfolio securities in lieu
of cash.  Securities issued in a distribution in kind will be readily
marketable, although shareholders receiving distributions in kind may incur
brokerage commissions when subsequently redeeming shares of those securities.


                                NET ASSET VALUE

        The Trust will not calculate the net asset value of the Funds and
Portfolios on certain holidays.  On those days, securities held by a Fund may
nevertheless be actively traded, and the value of the Fund's shares could be
significantly affected.

        The assets of each Fund and Portfolio are valued according to generally
accepted accounting principles and applicable law.  Generally, a Fund's or
Portfolio's investments are valued at market value or, in the absence of a
market value with respect to any portfolio securities, at fair value as
determined by or under the direction of the Trust's Board of Trustees:

        o       A security that is primarily traded on a U.S. or foreign
                exchange (including securities traded through the National
                Association of Securities Dealers, Inc. Automated Quotation
                System ("NASDAQ")) is valued at the last sale price on that
                exchange or, if there were no sales during the day, at the
                current quoted bid price.

        o       Securities that are primarily traded on foreign exchanges are
                generally valued at the preceding closing values of such
                securities on their respective exchanges, except when an
                occurrence subsequent to the time a value was so established is
                likely to have changed the value, then the fair value of those
                securities will be determined by consideration of other factors
                by or under the direction of the Trust's Board of Trustees or
                its delegates.

        o       Over-the-counter securities that are not reported on the NASDAQ
                System and securities listed or traded on certain foreign
                exchanges whose operations are similar



                                      B-41
<PAGE>   92
                to the U.S. over-the-counter market are valued on the basis of
                the bid price at the close of business on each day.

        o       An option is generally valued at the last sale price or, in the
                absence of a last sale price, the last offer price.

        o       Investments in U.S. Government Securities (other than short-term
                securities) are valued at the average of the quoted bid and
                asked prices in the over-the-counter market.

        o       Short-term investments that mature in 60 days or less are valued
                at amortized cost when the Board of Trustees determines that
                this constitutes fair value; assets of the Global Money Fund are
                also valued at amortized cost.

        o       The value of a futures contract equals the unrealized gain or
                loss on the contract, which is determined by marking the
                contract to the current settlement price for a like contract
                acquired on the day on which the futures contract is being
                valued.  A settlement price may not be used if the market makes
                a limited move with respect to the security or index underlying
                the futures contract.  In such event, the futures contract will
                be valued at a fair market price to be determined by or under
                the direction of the Trust's Board of Trustees.

        o       Shares of open-end investment companies are valued at the net
                asset value per share last or, contemporaneously calculated.

        In carrying out the Board's valuation policies, First Data Investor
Services Group, Inc. ("FDISG"), a wholly-owned subsidiary of First Data
Corporation, as sub-administrator, may consult with one or more independent
pricing services ("Pricing Services") retained by the Trust.  Debt securities
of U.S. issuers (other than U.S. Government Securities and short-term
investments) are valued by FDISG, as sub-administrator, after consultation with
the Pricing Service.  The procedures of the Pricing Service are reviewed
periodically by the officers of the Trust under the general supervision and
responsibility of the Board of Trustees.

        VALUATION OF THE GLOBAL MONEY FUND.  The valuation of the portfolio
securities of the Global Money Fund is based upon its amortized costs, which
does not take into account unrealized capital gains or losses.  Amortized cost
valuation involves initially valuing an instrument at its cost and thereafter
assuming a constant amortization to maturity of any discount or premium,
regardless of the impact of fluctuating interest rates on the market value of
the instrument.  While this method provides certainty in valuation, it may
result in periods during which value, as determined by amortized cost, is
higher or lower than the price the Fund would receive if it sold the instrument.

        The use by the Global Money Fund of the amortized cost method of
valuing its respective portfolio securities is permitted by a rule adopted by
the SEC.  Under this rule, the Global Money Fund must maintain a
dollar-weighted average portfolio maturity of 90 days or less, purchase



                                      B-42
<PAGE>   93
only instruments having remaining maturities of thirteen months or less and
invest only in securities determined by the Board of Trustees of the Trust to
present minimal credit risks and meet certain rating criteria described under
"Investment Objectives and Policies of the Funds -- Money Market Quality and
Maturity Requirements" above.  Pursuant to the rule, the Board of Trustees also
has established procedures designed to stabilize, to the extent reasonably
possible, the Fund's price per share as computed for the purpose of sales and
redemptions at $1.00.  Such procedures include review of the Fund's portfolio
holdings by the Board of Trustees, at such intervals as it may deem
appropriate, to determine whether the Fund's net asset values calculated by
using available market quotations or market equivalents deviates from $1.00 per
share based on amortized cost.

        The rule also provides that the extent of any deviation between the
Fund's net asset values based upon available market quotations or market
equivalents and the $1.00 per share net asset values based on amortized cost
must be examined by the Board of Trustees.  In the event the Board of Trustees
determines that a deviation exists which may result in material dilution or
other unfair results to investors or existing shareholders, pursuant to the rule
the Board of Trustees must cause the Trust to take such corrective action as the
Board deems necessary and appropriate including:  selling portfolio instruments
prior to maturity to realize capital gains or losses or shorten average
portfolio maturity; withholding dividends or paying distributions from capital
or capital gains; redeeming shares in kind; or establishing a net asset value
per share by using available market quotations.

                                  PERFORMANCE

        From time to time, the Trust may quote the performance of a Portfolio or
Fund in terms of yield, effective yield, actual distributions, total return or
capital appreciation in reports or other communications to shareholders or in
advertising material.  Fund or Portfolio performance will be advertised only if
accompanied by the comparable performance for the corresponding separate
account.

        ANNUITY CONTRACT OWNER VALUES WILL DEPEND NOT ONLY ON THE PERFORMANCE
OF THE FUNDS OR PORTFOLIOS, BUT ALSO ON THE MORTALITY AND EXPENSE RISK CHARGES,
THE ADMINISTRATIVE CHARGES, AND ANY APPLICABLE SALES CHARGES UNDER THE ANNUITY
CONTRACTS.  THE TOTAL RETURNS OF THE FUNDS REFLECT THE AGREEMENT OF SIERRA
ADVISORS TO VOLUNTARILY WAIVE FEES AND BEAR CERTAIN EXPENSES.  TOTAL RETURNS
WOULD HAVE BEEN LOWER IF THESE FEES AND EXPENSES HAD NOT BEEN WAIVED.

GLOBAL MONEY FUND YIELD INFORMATION

        The "yield" of the Global Money Fund refers to the income generated by
an investment in the Fund over a 7-day period (which period will be stated in
the advertisement).  This income is then "annualized."  That is, the amount of
income generated by the investment during that week is assumed to be generated
each week over a 52-week period and is shown as a percentage of the investment.
The "effective yield" is calculated similarly but, when annualized, the income
earned



                                      B-43
<PAGE>   94
by an investment in a Fund is assumed to be reinvested. The "effective yield"
will be slightly higher than the "yield" because of the compounding effect of
this assumed reinvestment.

        The yield for the Global Money Fund is computed by:  (1) determining the
net change, exclusive of capital changes, in the value of a hypothetical
pre-existing account in the Fund having a balance of one share at the beginning
of a seven calendar day period for which yield is to be quoted, (2) subtracting
a hypothetical charge reflecting deductions from shareholder accounts, (3)
dividing the net change by the value of the account at the beginning of the
period to obtain the base period return, and (4) annualizing the results (i.e.,
multiplying the base period return by 365/7).  The net change in the value of
the account reflects the value of additional share purchased with dividends
declared on the original share and any such additional shares and income
received or accrued but not declared as a dividend, but does not include
realized gains and losses or unrealized appreciation or depreciation.  In
addition, the Global Money Fund may calculate a compounded effective annualized
yield by adding 1 to the base period return (calculated as described above),
raising the sum to a power equal to 365/7 and subtracting 1.

        Based upon the foregoing calculation, for the 7-day period ended
December 31, 1996, the yield for the Global Money Fund was 4.85%, and the
effective yield for the Global Money Fund for the same period was 4.97%.

        The Global Money Fund yield may be compared with the yields of other
investments.  It should not, however, be compared to the return on fixed rate
investments which guarantee rates of interest for specified periods, such as the
interest guarantees in an annuity contract or bank deposits.

YIELD INFORMATION

        From time to time, the Bond Funds and the Income, Value and Balance
Portfolios may advertise the 30-day "yield."  Yield refers to the income
generated by an investment in such Fund or Portfolio over the 30-day period
identified in the advertisement, and is computed by dividing the net investment
income per share earned by the Fund or Portfolio during the period by the net
asset value per share on the last day of the previous period.  This income is
"annualized" by assuming that the amount of income is generated each month over
a one-year period and is compounded semiannually.  The annualized income is then
shown as a percentage of the net asset value.

The yield formula prescribed by the SEC can be expressed as follows:

                                             6
                        YIELD = 2[((a-b) + 1) - 1]
                                    ---
                                    cd

Where:  a = dividends and interest earned during the period.

        b = expenses accrued for the period (net of




                                      B-44
<PAGE>   95
                reimbursement).

        c =     the average daily number of shares outstanding during the period
                that were entitled to receive dividends.

        d =     the maximum offering price per share on the last day of the
                period.

        For the purpose of determining the interest earned (variable "a" in the
formula) on debt obligations that were purchased by one of the Funds at a
discount or premium, the formula generally calls for amortization of the
discount or premium; the amortization schedule will be adjusted monthly to
reflect changes in the market values of the debt obligations.

        Based on the foregoing calculation, for the 30-day period ended
December 31, 1996, the yields for the Short Term High Quality Bond, the Short
Term Global Government, the U.S. Government and the Corporate Income Funds were
5.85%, 4.03%, 5.74% and 6.55%, respectively.

TOTAL RETURN INFORMATION

        From time to time, a Fund or Portfolio, other than the Global Money
Fund, may advertise its "average annual total return" or "aggregate total
return" over various periods of time.  Such average annual total return figures
show the average percentage change in value of an investment in the Fund or
Portfolio from the beginning date of the measuring period to the end of the
measuring period.  These figures reflect changes in the price of the Fund's or
Portfolio's shares and assume that any income dividends and/or capital gains
distributions made by the Fund or Portfolio during the period were reinvested
in shares of that Fund or Portfolio.  Figures will be given for recent one-,
five- and ten-year periods (if applicable), and may be given for other periods
as well (such as from commencement of the Fund's or Portfolio's operations, or
on a year-by-year basis).

        When considering "average" total return figures for periods longer than
one year, it is important to note that the relevant Fund's or Portfolio's annual
total return for any one year in the period might have been greater or less than
the average for the entire period.  A Fund or Portfolio may also use "aggregate"
total return figures for various periods representing the cumulative change in
value of an investment in the Fund or Portfolio for a specific period (again
reflecting changes in the Fund's or Portfolio's share prices and assuming
reinvestment of dividends and distributions).  Aggregate total returns may be
shown by means of schedules, charts or graphs and may indicate subtotals of the
various components of total return (i.e., change in value of initial investment,
income dividends and capital gains distributions).

        Average annual total return is computed according to a formula
prescribed by the SEC.  The formula can be expressed as follows: P(1 + T)n =
ERV, where P = a hypothetical initial


                                      B-45
<PAGE>   96
payment of $1,000; T = average annual total return; n = number of years; and
ERV = ending redeemable value of a hypothetical $1,000 payment made at the
beginning of the designated time period as of the end of such period or the
life of the fund.  The formula for calculating aggregate total return can be
expressed as (ERV/P)-1.

        Based on the foregoing, the average annual total returns for the fiscal
year ended December 31, 1996 and from inception through December 31, 1996 and
the aggregate total returns for the Funds from inception through December 31,
1996, were as follows*:

        The total returns shown for the Funds are not an estimate or guarantee
of future performance and do not take into account charges at the annuity and
separate account level.

        The performance of any or all of the Funds or Portfolios may be
compared in advertisements and sales literature to the performance of other
variable annuity issuers in general and to the performance of particular types
of variable annuities investing in mutual funds, or series of mutual funds,
with investment objectives similar to each of the Funds.  Lipper Analytical
Services, Inc. ("Lipper") and the Variable Annuity Research and Data Service
("VARDS(R)") are independent services which monitor and rank the performance of
variable annuity issuers in each of the major categories of investment
objectives on an industry-wide basis.  Lipper's rankings include variable life
issuers as well as variable annuity issuers.  VARDS(R) rankings compare only
variable annuity issuers.  The performance analyses prepared


                                      B-46
<PAGE>   97
by Lipper and VARDS(R) rank such issuers on the basis of total return, assuming
reinvestment of dividends and distributions, but do not take sales charges,
redemption fees or certain expense deductions at the separate account level
into consideration.  In addition, VARDS(R) prepares risk adjusted rankings,
which consider the effects of market risk on total return performance.

        In addition, performance of each Fund or Portfolio may be compared in
advertisements and sales literature to the following benchmarks: (1) the
Standard & Poor's 500 Index, which represents an unmanaged weighted index of 500
industrial, transportation, utility and financial companies that represent
approximately 80% of the market capitalization of the United States equity
markets, widely regarded by investors as representative of the stock market; (2)
the Consumer Price Index, published by the U.S. Bureau of Labor Statistics, a
statistical measure of change, over time, in the prices of goods and services in
major expenditure groups and generally considered to be a measure of inflation;
(3) the Lehman Brothers Mutual Fund Short World Multi-Market Index, which
includes all debt instruments of the United States and 12 Lehman Major Countries
denominated in dollars with maturities of one to five years; (4) the Lehman
Brothers Mutual Fund U.S. Mortgage Index, which includes all agency
Mortgage-Backed Securities; (5) the Lehman Brothers Mutual Fund Debt BBB-Rated
Index, which represents all investment-grade corporate debt securities; (6) the
Morgan Stanley Capital International EAFE (Europe, Australia, Far East) Index,
which includes 1050 companies representing the stock markets of Europe,
Australia, New Zealand and the Far East; and (7) the U.S. Government 90 Day
Treasury Bill rate.  Generally, an index represents the market value of an
unmanaged group of securities, regarded by investors as representative of a
particular market.  An index does not reflect any asset-based charges for
investment management or other expenses.  The performance information may also
include evaluations of the funds published by nationally recognized ranking
services and by financial publications that are nationally recognized, such as
Business Week, Forbes, Institutional Investor, Money and The Wall Street
Journal.

                                     TAXES

        The following discussion of federal income tax consequences is based on
the Code and the regulations issued thereunder as in effect on the date of
this SAI.  New legislation, as well as administrative changes or court
decisions, may significantly change the conclusions expressed herein and may
have a retroactive effect with respect to the transactions contemplated herein.

        Each of the Funds and Portfolios intends to qualify as a "regulated
investment company" ("RIC") under Subchapter M of the Code.  A Fund or
Portfolio that is a RIC and distributes to its shareholders at least 90% of its
taxable net investment income (including, for this purpose, its net realized
short-term capital gains) and 90% of its tax-exempt interest income (reduced by
certain expenses), will not be liable for federal income taxes to the extent
its taxable net investment income and its net realized long-term and short-term
capital gains, if any, are distributed to its shareholders.

        A number of technical rules are prescribed for computing net investment
income and net capital gains.  For example, the Fund or Portfolio is generally
treated as receiving dividends on



                                      B-47

<PAGE>   98
the ex-dividend date.  Also, certain foreign currency losses and capital losses
arising after October 31 of a given year may be treated as if they arise on the
first day of the next taxable year.

        In order to qualify as a RIC under the Code, in addition to satisfying
the distribution requirement described above, each Fund or Portfolio must (a)
derive at least 90% of its gross income each taxable year from dividends,
interest, payments with respect to securities loans, gains from the sale or
other disposition of stock, securities, or foreign currencies, and certain
other related income, including, generally, certain gains from options,
futures, and forward contracts; (b) derive less than 30% of its gross income
each taxable year from the sale or other disposition of the following items if
held for less than three months: (i) stock or securities, (ii) options, futures
or forward contracts (other than options futures, or forward contracts on
foreign currencies), and (iii) foreign currencies (or options, futures, or
forward contracts on foreign currencies) that are not directly related to the
company's business of investing in stock or securities; and (c) diversify its
holdings so that, at the end of each fiscal quarter of the Fund's or
Portfolio's taxable year, (i) at least 50% of the market value of the Fund's
assets is represented by cash and cash items, U.S. Government Securities,
securities of other Registered Investment Companies ("RICs"), and other
securities, with such other securities limited, in respect of any one issuer,
to an amount that does not exceed 10% of the voting securities of such issuer
or 5% of the value of the Fund's or Portfolio's total assets; and (ii) not more
than 25% of the value of its assets is invested in the securities (other than
U.S. Government Securities and securities of other RICs) of any one issuer or
two or more issuers which the Fund or Portfolio controls and which are engaged
in the same, similar or related trades or businesses.

        If a Fund or Portfolio fails to qualify as a RIC for any year, all of
its income will be subject to tax at corporate rates, and its distributions
(including capital gain distributions) will be taxable as ordinary income
dividends to its shareholders to the extent of the Fund's or Portfolio's
current and accumulated earnings and profits.
   
        In addition to qualifying under subchapter M by meeting the requirements
described above, each Fund and Portfolio intends to qualify as diversified under
Subchapter L so that non-qualified variable annuity contracts funded by the
Trust will not fail to qualify as annuities for tax purposes.  In general, for a
Fund or Portfolio to meet the investment diversification requirements of
Subchapter L of the Code, Treasury regulation 1.817-5 requires that no more 
than 55% of the total value of the assets of the Fund or Portfolio be 
represented by any one investment, no more than 70% by any two investments, no
more than 80% by three investments and no more than 90% by four investments. 
Generally, for purposes of the regulations, all securities of the same issuer 
are treated as one investment.  In the context of U.S. Government Securities 
(including any security that is issued, guaranteed or insured by the United 
States or an instrumentality of the United States), each U.S. Government agency
or instrumentality is treated as a separate issuer.  In the context of shares of
registered investment companies (including shares of the Trust), each series,
fund or portfolio is treated as a separate issuer.  Compliance with the
Subchapter L regulations is tested on the last day of each calendar year
quarter.
    
        Notwithstanding the distribution requirement described above, which
only requires a Fund or Portfolio to distribute at least 90% of its annual
investment company taxable income and



                                      B-48

does not require any minimum distribution of net capital gain, a regulated
investment company is generally subject to a nondeductible 4% excise tax to the
extent it fails to distribute by the end of any calendar year at least 98% of
its ordinary income for that year and 98% of its capital gain net income for the
one-year period ending on October 31 of that year, plus certain other amounts.

        The excise tax is inapplicable to any RIC all of the shareholders of
which are either tax-exempt pension trusts or separate accounts of life
insurance companies funding variable contracts.  Although each Fund and
Portfolio believes that it is not subject to the excise tax, each Fund and
Portfolio intends to make the distributions required to avoid the imposition of
the tax, provided such payments and distributions are determined to be in the
best interest of such Fund's or Portfolio's shareholders.

        Dividends declared by a Fund or Portfolio in October, November, or
December of any year and payable to shareholders of record on a date in such
month will be deemed to have been paid by the Fund or Portfolio and received by
the shareholders on December 31 of that year if paid by the Fund or Portfolio
at any time during the following January.

              DESCRIPTION OF S&P, MOODY'S, DUFF AND FITCH RATINGS

DESCRIPTION OF S&P CORPORATE BOND RATINGS

        AAA-Debt rated AAA has the highest rating assigned by S&P.  Capacity to
pay interest and repay principal is extremely strong.

        AA-Debt rated AA has a very strong capacity to pay interest and repay
principal and differs from the highest rated debt only in small degree.

        A-Debt rated A has a strong capacity to pay interest and repay
principal, although it is somewhat more susceptible to adverse effects of
changes in circumstances and economic conditions than debt in higher-rated
categories.

        BBB-Debt rated BBB is regarded as having an adequate capacity to pay
interest and repay principal.  Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher-rated categories.

        BB, B, CCC, CC or C-Debt rated BB, B, CCC, CC or C is regarded as
having predominantly speculative characteristics with respect to capacity to
pay interest and repay principal.  BB indicates the least degree of speculation
and C the highest degree of speculation.  While such debt will likely have some
quality and protective characteristics, these are outweighed by large
uncertainties or major risk exposures to adverse conditions.

BB      Debt rated 'BB' has less near-term vulnerability to default than other
        speculative grade debt.  However, it faces major ongoing uncertainties
        or exposure to adverse business, financial, or economic conditions that
        could lead to inadequate capacity to meet timely interest and principal
        payments.  The 'BB' rating category is also used for debt subordinated
        to senior debt that is assigned an actual or implied 'BBB-' rating.

B       Debt rate 'B' has greater vulnerability to default but presently has the
        capacity to meet interest payments and principal repayments.  Adverse
        business, financial, or economic conditions would likely impair capacity
        or willingness to pay interest and repay principal.  The 'B' rating
        category also is used for debt subordinated to senior debt that is
        assigned an actual or implied 'BB' or 'BB-' rating.

CCC     Debt rated 'CCC' has a current identifiable vulnerability to default,
        and is dependent on favorable business, financial, and economic
        conditions to meet timely payment of interest and repayment of
        principal.  In the event of adverse business, financial, or economic
        conditions, it is not likely to have the capacity to pay interest and
        repay principal.  The 'CCC' rating category also is used for debt
        subordinated to senior debt that is assigned an actual or implied 'B' or
        'B-' rating.



                                      B-50
<PAGE>   101
CC      The rating 'CC' is typically applied to debt subordinated to senior
        debt which is assigned an actual or implied 'CCC' rating.

C       The rating 'C' is typically applied to debt subordinated to senior debt
        which is assigned an actual or implied 'CCC-' debt rating. The 'C'
        rating may be used to cover a situation where a bankruptcy petition has
        been filed, but debt service payments are continued.

        C1-Debt rated C1 is reserved for income bonds on which no interest is
being paid.

        D-Debt is rated D when the issue is in payment default, or the obligor
has filed for bankruptcy. The D rating is used when interest or principal
payments are not made on the date due, even if the applicable grace period has
not expired, unless S&P believes that such payments will be made during such
grace period.

        Plus (+) or minus (-): The ratings from AA to CCC may be modified by
the addition of a plus or minus sign to show relative standing within the major
rating categories.

DESCRIPTION OF MOODY'S CORPORATE BOND RATINGS

        Aaa-Bonds which are rated Aaa are judged to be of the best quality.
They carry the smallest degree of investment risk and are generally referred to
as "gilt-edge." Interest payments are protected by a large or by an
exceptionally stable margin and principal is secure. While the various
protective elements are likely to change, such changes as can be visualized are
most unlikely to impair the fundamentally strong position of such issues.

        Aa-Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risk appear somewhat larger than the Aaa securities.

        A-Bonds which are rated A possess many favorable investment attributes
and are to be considered as upper-medium grade obligations. Factors giving
security to principal and interest are considered adequate, but elements may be
present which suggest a susceptibility to impairment some time in the future.

        Baa-Bonds which are rated Baa are considered as medium-grade obligations
(i.e., they are neither highly protected nor poorly secured). Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.

        Ba-Bonds which are rated Ba are judged to have speculative elements;
their future cannot be considered as well-assured. Often the protection of
interest and principal payments may be


                                      B-51
<PAGE>   102
very moderate and thereby not well safeguarded during both good and bad times
over the future. Uncertainty of position characterizes bonds in this class.

        B-Bonds which are rated B generally lack characteristics of the
desirable investment. Assurance of interest and principal payments or of
maintenance of other terms of the contract over any long period of time may be
small.

        Caa-Bonds which are rated Caa are of poor standing. Such issues may be
in default or there may be present elements of danger with respect to principal
or interest.

        Ca-Bonds which are rated Ca represent obligations which are speculative
in a high degree. Such issues are often in default or have other marked
shortcomings.

        C-Bonds which are rated C are the lowest class of bonds, and issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.

        Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from Aa through B in its corporate bond rating system. The
modifier 1 indicates that the security ranks in the higher end of its generic
rating category; the modifier 2 indicates a mid-range ranking; and the modifier
3 indicates that the security ranks in the lower end of its generic rating
category.

DESCRIPTION OF DUFF CORPORATE BOND RATINGS

        AAA-Highest credit quality. The risk factors are negligible, being only
slightly more than for risk-free U.S. Treasury debt.

        AA-High credit quality. Protection factors are strong. Risk is modest
but may vary slightly from time to time because of economic conditions.

        A-Protection factors are average but adequate. However, risk factors
are more variable and greater in periods of economic stress.

        BBB-Below average protection factors but still considered sufficient
for prudent investment. Considerable variability in risk during economic cycles.

BB+     Below investment grade but deemed likely to meet obligations when due.

BB      Present or prospective financial protection factors fluctuate according
        to industry conditions or company fortunes.

BB-     Overall quality may move up or down frequently within this category.


                                      B-52
<PAGE>   103
B+      Below investment grade and possessing risk that obligations will not be
        met when due.

B       Financial protection factors will fluctuate widely according to
        economic cycles, industry conditions and/or company fortunes.

B-      Potential exists for frequent changes in the rating within this category
        or into a higher or lower rating grade.

CCC     Well below investment grade securities. Considerable uncertainty exists
        as to timely payment of principal, interest or preferred dividends.
        Protection factors are narrow and risk can be substantial with
        unfavorable economic/industry conditions, and/or with unfavorable
        company developments.

DD      Defaulted debt obligations. Issuer failed to meet scheduled principal
        and/or interest payments.

DP      Preferred stock with dividend arrearages.

DESCRIPTION OF FITCH CORPORATE BOND RATINGS

        AAA-Bonds considered to be investment grade and of the highest credit
quality. The obligor has an exceptionally strong ability to pay interest and
repay principal, which is unlikely to be affected by reasonably foreseeable
events.

        AA-Bonds considered to be investment grade and of high credit quality.
The obligor's ability to pay interest and repay principal is very strong,
although not quite as strong as bonds rated AAA.  Because bonds rated in the
AAA and AA categories are not significantly vulnerable to foreseeable future
developments, short-term debt of these issuers is generally rated F-1+.

        A-Bonds considered to be investment grade and of high credit quality.
The obligor's ability to pay interest and to repay principal is considered to
be strong, but may be more vulnerable to adverse changes in economic conditions
and circumstances than bonds with higher ratings.

        BBB-Bonds considered to be investment grade and of satisfactory credit
quality. The obligor's ability to pay interest and to repay principal is
considered to be adequate. Adverse changes in economic conditions and
circumstances, however, are more likely to have an adverse impact on these
bonds, and therefore impair timely payment. The likelihood that the ratings of
these bonds will fall below investment grade is higher than for bonds with
higher ratings.

BB      Bonds are considered speculative. The obligor's ability to pay interest
        and repay principal may be affected over time by adverse economic
        changes. However, business and financial alternatives can be identified
        which could assist the obligor in satisfying its debt service
        requirements.


                                      B-53
<PAGE>   104
B       Bonds are considered highly speculative.  While bonds in this class are
        currently meeting debt service requirements, the probability of
        continued timely payment of principal and interest reflects the
        obligor's limited margin of safety and the need for reasonable business
        and economic activity throughout the life of the issue.

CCC     Bonds have certain identifiable characteristics which, if not remedied,
        may lead to default.  The ability to meet obligations requires an
        advantageous business and economic environment.

CC      Bonds are minimally protected.  Default in payment of interest and/or
        principal seems probable over time.

C       Bonds are in imminent default in payment of interest or principal.

DDD, DD, and D

        Bonds are in default on interest and/or principal payments.  Such bonds
        are extremely speculative and should be valued on the basis of their
        ultimate recovery value in liquidation or reorganization of the obligor.
        'DDD' represents the highest potential for recovery on these bonds, and
        'D' represents the lowest potential for recovery.

PLUS (+) MINUS (-)

        Plus and minus signs are used with a rating symbol to indicate the
        relative position of a credit within the rating category.  Plus and
        minus signs, however, are not used in the DDD, DD, or D categories.

DESCRIPTION OF S&P COMMERCIAL PAPER RATINGS

A-1     This highest category indicates that the degree of safety regarding
        timely payment is strong.  Debt determined to possess extremely strong
        safety characteristics is denoted with a plus sign (+) designation.

A-2     Capacity for timely payment on issues with this designation is
        satisfactory.  However, the relative degree of safety is not as high as
        for issues designated 'A-1'.

A-3     Debt carrying this designation has an adequate capacity for timely
        payment.  It is, however, more vulnerable to the adverse effects of
        changes in circumstances than obligations carrying the higher
        designations.

B       Debt rated 'B' is regarded as having only speculative capacity for
        timely payment.

C       This rating is assigned to short-term debt obligations with a doubtful
        capacity for payment.

D       This rating indicates that the obligation is in payment default.



                                      B-54
<PAGE>   105
DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS

PRIME-1  Issuers rated Prime-1 (or supporting institutions) have superior
ability for repayment of senior short-term debt obligations.  Prime-1 repayment
ability will often be evidenced by many of the following characteristics:

- --      Leading market positions in well established industries.
- --      High rates of return on funds employed.
- --      Conservative capitalization structure with moderate reliance on debt and
        ample asset protection.
- --      Broad margins in earnings coverage of fixed financial charges and high
        internal cash generation.
- --      Well-established access to a range of financial markets and assured
        sources of alternate liquidity.

PRIME-2  Issuers rated Prime-2 (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations.  This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation.  Capitalization characteristics, while still appropriate, may be more
affected by external conditions.  Ample alternate liquidity is maintained.

PRIME-3  Issuers rated Prime-3 (or supporting institutions) have an acceptable
ability for repayment of senior short-term obligations.  The effect of industry
characteristics and market compositions may be more pronounced.  Variability in
earnings and profitability may result in changes in the level of debt protection
measurements and may require relatively high financial leverage.  Adequate
alternate liquidity is maintained.

NOT PRIME  Issuers rate Not Prime do not fall within any of the Prime rating
categories.

DESCRIPTION OF DUFF'S COMMERCIAL PAPER RATINGS

Duff 1+         Highest certainty of timely payment.  Short-term liquidity,
                including internal operating factors and/or access to
                alternative sources of funds, is outstanding, and safety is just
                below risk-free U.S. Treasury short-term obligations.

Duff 1          Very high certainty of timely payment.  Liquidity factors are
                excellent and supported by good fundamental protection factors.
                Risk factors are minor.

Duff 1-         High certainty of timely payment.  Liquidity factors are strong
                and supported by good fundamental protection factors.  Risk
                factors are very small.

                GOOD GRADE

Duff 2          Good certainty of timely payment.  Liquidity factors and
                company fundamentals are sound.  Although ongoing funding needs
                may enlarge total financing requirements, access to capital
                markets is good.  Risk factors are small.



                                      B-55
<PAGE>   106
                SATISFACTORY GRADE

Duff 3          Satisfactory liquidity and other protection factors qualify
        issue as to investment grade.  Risk factors are larger and subject to
        more variation.  Nevertheless, timely payment is expected.

                NON-INVESTMENT GRADE

Duff 4          Speculative investment characteristics.  Liquidity is not
        sufficient to insure against disruption in debt service.  Operating
        factors and market access may be subject to a high degree of variation.

                DEFAULT

Duff 5          Issuer failed to meet scheduled principal and/or interest
        payments.


DESCRIPTION OF FITCH'S COMMERCIAL PAPER RATINGS

F-1+    Exceptionally Strong Credit Quality.  Issues assigned this rating are
        regarded as having the strongest degree of assurance for timely payment.

F-1     Very Strong Credit Quality.  Issues assigned this rating reflect an
        assurance of timely payment only slightly less in degree than issues
        rated 'F-1+'.

F-2     Good Credit Quality.  Issues assigned this rating have a satisfactory
        degree of assurance for timely payment, but the margin of safety is not
        as great as for issues assigned 'F-1+' and 'F-1' ratings.

F-3     Fair Credit Quality.  Issues assigned this rating have characteristics
        suggesting that the degree of assurance for timely payment is adequate,
        however, near-term adverse changes could cause these securities to be
        rated below investment grade.

F-S     Weak Credit Quality. Issues assigned this rating have characteristics
        suggesting a minimal degree of assurance for timely payment and are
        vulnerable to near-term adverse changes in financial and economic
        conditions.

D       Default.  Issues assigned this rating are in actual or imminent payment
        default.

LOC     The symbol LOC indicates that the rating is based on a letter of credit
        issued by a commercial bank.

Item 27. Indemnification

             Article VIII of the Registrant's Agreement and Declaration of Trust
provides in relevant part:

             The Trust shall indemnify each of its Trustees and officers
             (including persons who serve at the Trust's request as directors,
             officers or trustees of another organization in which the Trust has
             any interest as a shareholder, creditor or otherwise) (hereinafter
             referred to as a "Covered Person") against all liabilities and
             expenses, including but not limited to amounts paid in satisfaction
             of judgments, in compromise or as fines and penalties, and counsel
             fees reasonably incurred by any Covered Person in connection with
             the defense or disposition of any action, suit or other proceeding,
             whether civil or criminal, before any court or administrative or
             legislative body, in which such Covered Person may be or may have
             been involved as a party or otherwise or with which such Covered
             Person may be or may have been threatened, while in office or
             thereafter, by reason of being or having been such a Covered Person
             except with respect to any matter as to which such Covered Person
             shall have been finally adjudicated in any such action, suit or
             other proceeding to be liable to the Trust or its Shareholders by
             reason of wilful misfeasance, bad faith, gross negligence or
             reckless disregard of the duties involved in the conduct of such
             Covered Person's office. Expenses, including counsel fees so
             incurred by any such Covered Person (but excluding amounts paid in
             satisfaction of judgments, in compromise or as fines or penalties),
             shall be paid from time to time by the Trust in advance of the
             final disposition of any such action, suit or proceeding upon
             receipt of an undertaking by or on behalf of such Covered Person to
             repay amounts so paid to the Trust if it is ultimately determined
             that indemnification of such expenses is not authorized under this
             Article; provided, however, that either (a) such Covered Person
             shall have provided appropriate security for such undertaking, (b)
             the Trust shall be insured against losses arising from any such
             advance payments or (c) either a majority of the disinterested
             Trustees acting on the matter (provided that a majority of the
             disinterested Trustees then in office act on the matter), or
             independent legal counsel in a written opinion, shall have
             determined, based upon a review of readily available facts (as
             opposed to a full trial type inquiry) that there is reason to
             believe that such Covered Person will be found entitled to
             indemnification under this Article.


                                       C-8
<PAGE>   116
             As to any matter disposed of (whether by a compromise payment,
             pursuant to a consent decree or otherwise) without an adjudication
             by a court, or by any other body before which the proceeding was
             brought, that such Covered Person is liable to the Trust or its
             Shareholders by reason of wilful misfeasance, bad faith, gross
             negligence or reckless disregard of the duties involved in the
             conduct of his or her office, indemnification shall be provided if
             (a) approved, after notice that it involves such indemnification,
             by at least a majority of the disinterested Trustees acting on the
             matter (provided that a majority of the disinterested Trustees then
             in office act on the matter) upon a determination, based upon a
             review of readily available facts (as opposed to a full trial type
             inquiry) that such Covered Person is not liable to the Trust or its
             Shareholders by reasons of wilful misfeasance, bad faith, gross
             negligence or reckless disregard of the duties involved in the
             conduct of his or her office, or (b) there has been obtained an
             opinion in writing of independent legal counsel, based upon a
             review of readily available facts (as opposed to a full trial type
             inquiry) to the effect that such indemnification would not protect
             such Person against any liability to the Trust to which he or she
             would otherwise be subject by reason of wilful misfeasance, bad
             faith, gross negligence or reckless disregard of the duties
             involved in the conduct of his office. Any approval pursuant to
             this Section shall not prevent the recovery from any Covered Person
             of any amount paid to such Covered Person in accordance with this
             Section as indemnification if such Covered Person is subsequently
             adjudicated by a court of competent jurisdiction to have been
             liable to the Trust or its Shareholders by reason of wilful
             misfeasance, bad faith, gross negligence or reckless disregard of
             the duties involved in the conduct of such Covered Person's office.

             Section 9 of the Sub-Adviser Agreements that are filed as Exhibits
5(b)-2 and 5(b)-7 to this Registration Statement are hereby incorporated by
reference in response to this item. They provide that, in the absence of willful
misfeasance, bad faith or gross negligence on the part of J.P. Morgan, or
reckless disregard of its obligations and duties thereunder ("Disqualifying
Conduct"), J.P. Morgan shall not be subject to any liability to the Trust or the
Fund, or to any shareholder of the Fund, for any act or omission in the course
of, or connected with, rendering services hereunder. This Section further
provides that Sierra Advisors shall indemnify and hold harmless J.P. Morgan from
and against all claims, losses, liabilities or damages (including reasonable
attorneys' fees and other related expenses) (collectively, "Losses"), howsoever
arising under this Agreement or the performance by J.P. Morgan of its duties
thereunder; provided, however, that nothing contained therein shall require that
J.P. Morgan be indemnified for Losses resulting from Disqualifying Conduct.

             Section 11 of the Sub-Adviser Agreements that are filed as Exhibits
5(b)-6 and 5(b)-9 to this Registration Statement are hereby incorporated by
reference in response to this item. They provide that Sierra Advisors will
indemnify and hold harmless Janus from and against any and all claims, losses,
liabilities or damages (including reasonable attorneys' fees and other related
expenses), howsoever arising from or in connection with these Sub-Adviser
Agreements or the performance by Janus of its duties thereunder; provided,
however, that nothing contained therein shall require that Janus be indemnified
for Disqualifying Conduct.
    

             Section 12 of the Participation Agreement that is filed as Exhibit
6(b) to this Registration Statement is hereby incorporated by reference in
response to this item. Section 12.1 thereof provides that American General will
indemnify the Trust and Sierra Services and their directors, trustees, officers
and controlling persons from losses and costs due to misstatements or omissions
of material facts for which American General is responsible in its registration
statement relating to annuities funded through the Trust or otherwise or due to
American General's failure to meet its obligations under the Participation
Agreement. Section 12.2 thereof provides that Sierra Services will indemnify the
Trust, American General, American General Securities and their directors,
trustees, officers and controlling persons from losses and costs due to any
misstatements or omissions of material facts for which Sierra Services or its
affiliates are responsible in American General registration statements relating
to annuities funded through the Trust or otherwise or as a result of any failure
by the Trust or Sierra Services to meet its obligations under the Participation
Agreement.

             The Agreement filed as Exhibit 11(d) to this Registration Statement
is hereby incorporated by reference in response to this item. Pursuant to that
Agreement, Sierra Advisors and Sierra Services agree to indemnify American
General and American General Securities with respect to liabilities arising out
of the negligence or bad faith of Sierra Services, Sierra Advisors or any
sub-advisor to the Trust in performing their obligations to the Trust, including
the obligations of Sierra Advisors and the sub-advisors to operate the Trust in
compliance with Sub-Chapter M and Section 817(h) of the Internal Revenue Code of
1986, as amended. Sierra Advisors and Sierra Services also agree to indemnify
American General and American General Securities for 50% of any other
liabilities or costs that they may incur as a result of any failure of the Trust
to comply with Sub-Chapter M or Section 817(h) that does not result from such
negligence or bad faith.

             Insofar as indemnification for liability arising under the
Securities Act of 1933, as amended (the "1933 Act"), may be permitted to
Trustees, officers and controlling persons of Registrant pursuant to the
foregoing provisions, or otherwise, Registrant has been advised that, in the
opinion of the Securities and Exchange

                                      C-10
<PAGE>   118
Commission, such indemnification is against public policy as expressed in the
1933 Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by Registrant
of expenses incurred or paid by a Trustee, officer or controlling person of
Registrant in the successful defense of any action, suit or proceeding) is
asserted by such Trustee, officer or controlling person in connection with the
securities being registered, Registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the 1933 Act and will be governed by the
final adjudication of such issue.
