                             NORTH AMERICAN FUNDS
                           Supplement to Prospectus
                            dated August 29, 1995

        On January 1, 1996, North American Life Assurance Company ("NAL") and
The Manufacturers Life Insurance Company merged with the combined company
retaining the name The Manufacturers Life Insurance Company ("Manulife").  NAL
is the ultimate parent of NASL Financial Services, Inc. ("NASL Financial"), the
investment adviser to the North American Funds (the "Fund").  Manulife, like
NAL, is a Canadian mutual life insurance company based in Toronto, Canada.  The
merger may be considered to give rise to the assignment and automatic
termination of the investment advisory agreement between NASL Financial and the
Fund (the "Investment Advisory Agreement") as well as the assignment and
automatic termination of each of the underlying subadvisory agreements for each
of the porfolois (including the consulting agreement Salomon Brothers Asset
Management Inc. ("SBAM") and Salomon Brothers Asset Management Limited ("SBAM
Limited") relating to the Strategic Income Portfolio) (collectively, the
"Existing Agreements").  Therefore, at the Fund's Board of Trustees meeting
held September 28-29, 1995, the Trustees of the Fund (including all the
noninterested Trustees) voted to approve a new advisory agreement between the
Fund and NASL Financial, new subadvisory agreements between NASL Financial and
each of the subadvisors, and a new consulting agreement between SBAM and SBAM
Limited (collectively, the "New Agreements"), and to submit the New Agreements
to shareholders for their consideration.  The New Agreements were approved by
shareholders of each portfolio of the Fund on December 5, 1995.  The New
Agreements are substantially identical to the Existing Agreements, except with
respect to the time period for termination of the expense reimbursement payable
by NASL Financial under the Investment Advisory Agreement.  (Under the New
Investment Advisory Agreement the expense reimburement is terminable at any
time on 30 days' written notice.  Under the Existing Investment Advisory
Agreement, the expense reimbursement was terminable by NASL Financial on
October 31st of each year on 30 days' written notice).  THEREFORE, THE NEW
AGREEMENTS WILL NOT RESULT IN ANY CHANGES IN ADVISORY FEES PAID BY THE FUND,
THE INVESTMENT MANAGEMENT OR OPERATIONS OF EITHER NASL FINANCIAL OR THE
SUBADVISERS, THE INVESTMENT PERSONNEL MANAGING THE FUND OR THE SHAREHOLDER
SERVICES OR OTHER BUSINESS ACTIVITIES OF THE FUND.

                       PROSPECTUS DATED AUGUST 29, 1995

                      SUPPLEMENT FOR MARYLAND RESIDENTS
                            DATED AUGUST 29, 1995

        The "Investment Portfolios" section begins on page 23 of the Prospectus
and the "Risk Factors" section begins on page 36 of the Prospectus.

        Each of the Portfolios may enter into Hedging and Other Strategic
Transactions (also referred to as derivative transactions) for hedging purposes
only.  

        Hedging and Other Strategic Transactions have special risks associated
with them, including possible default by the counterparty to the transaction,
illiquidity and, to the extent the subadviser's view as to certain market
movements is incorrect, the risk that the use of the Hedging and Other
Strategic Transactions could result in losses greater than if they had not
been used.  Even derivatives used for hedging purposes may entail risk and may
contribute to increasing the volatility of a Portfolio. 

        Each Portfolio anticipates engaging in Hedging and Other Strategic
Transactions (derivative transactions) to the extent described below:

        The International Growth and Income Fund, the Global Growth Fund, the
Growth and Income Fund and the Strategic Income Fund expect that, under normal
market conditions, a maximum of 25%, 20%, 25% and 100%, respectively, of each
Portfolio's foreign currency exposure would be hedged back into the U.S. dollar 
through the use of forward foreign currency exchange contracts.  

        The Investment Quality Bond Fund expects that, under normal market
conditions, a maximum of 25% of the Portfolio's total assets will be exposed to
the financial markets through the use of futures contracts and options on
futures contracts.

        The Growth Fund and the Asset Allocation Fund expect that, under normal
market conditions, a maximum of 25% of each Portfolio's total assets will be
exposed to the financial markets through the use of futures contracts.  

        The National Municipal Bond Fund does not presently anticipate that any
of the strategies referred to under Hedging and Other Strategic Transaction
will be used to a significant degree.

        The U.S. Government Securities Fund and the Money Market Fund are not
currently authorized to use any of the various investment strategies referred
to under "Hedging and Other Strategic Transactions."

North American Funds (the "Fund") is an open-end, diversified management
investment company(mutual fund) providing a range of investment options through
ten separate investment portfolios (the "Portfolios"), each of which has a
specific investment objective.  This Prospectus relates to the following
portfolios of the Fund:
     The GLOBAL GROWTH FUND seeks long-term capital appreciation, by investing
primarily in a global portfolio of equity securities and securities convertible
into or exercisable for equity securities.
     The GROWTH FUND seeks long-term growth of capital by investing primarily
in common stocks and securities convertible into or carrying the right to buy
common stocks.
     The GROWTH AND INCOME FUND seeks long-term growth of capital and income,
consistent with prudent investment risk, by investing primarily in a
diversified portfolio of common stocks of United States issuers which the
Subadviser believes are of high quality.
     The INTERNATIONAL GROWTH AND INCOME FUND seeks to provide long-term growth
of capital and income by investing in a portfolio of securities of foreign
issuers.
     The ASSET ALLOCATION FUND seeks the highest total return consistent with a
moderate level of risk tolerance.  This Portfolio attempts to limit the decline
in portfolio value in very adverse market conditions to 10% over any twelve
month period.  The Asset Allocation Fund will invest in a combination of
equity, fixed-income and money market securities.  The Subadviser retains
absolute discretion to determine the amount of the Portfolio's assets invested
in each category of securities at all times.  There can be no assurance that
the 10% limit on the decline in portfolio value will not be exceeded.
     The STRATEGIC INCOME FUND seeks a high level of total return consistent
with preservation of capital by giving its Subadviser broad discretion to
deploy the Portfolio's assets among certain segments of the fixed-income market
as the Subadviser believes will best contribute to achievement of the
Portfolio's investment objective.
     The INVESTMENT QUALITY BOND FUND seeks a high level of current income
consistent with the maintenance of principal and liquidity, by investing
primarily in a diversified portfolio of investment grade corporate bonds and
U.S. Government bonds with intermediate to longer term maturities.  Up to 20%
of the Fund's assets may be invested in debt securities rated below investment
grade.
     The U.S. GOVERNMENT SECURITIES FUND seeks a high level of current income
consistent with preservation of capital and maintenance of liquidity by
investing in securities issued or  guaranteed by the U.S. Government, its
agencies or instrumentalities, primarily Government National Mortgage
Association mortgage-backed certificates popularly known as "Ginnie Maes."
     The NATIONAL MUNICIPAL BOND FUND seeks to achieve a high level of current
income which is exempt from regular federal income taxes, consistent with the
preservation of capital, by investing primarily in a portfolio of municipal
obligations.  The Portfolio will not invest in municipal obligations that are
rated below investment grade at the time of purchase.
     The MONEY MARKET FUND seeks maximum current income consistent with
preservation of principal and liquidity as is available from investing only in
high quality, U.S. dollar denominated money market instruments with maturities
of thirteen months or less.
     THERE CAN BE NO ASSURANCE THAT ANY PORTFOLIO WILL ACHIEVE ITS INVESTMENT
OBJECTIVE AND EACH OF THE PORTFOLIOS MAY EMPLOY CERTAIN INVESTMENT PRACTICES
WHICH INVOLVE SPECIAL RISK CONSIDERATIONS.  SEE ALSO THE DISCUSSION OF "RISK
FACTORS" IN THIS PROSPECTUS.  IN PURSUING THEIR INVESTMENT OBJECTIVES, THE
STRATEGIC INCOME FUND RESERVES THE RIGHT TO INVEST WITHOUT LIMITATION, AND THE
INVESTMENT QUALITY BOND FUND MAY INVEST UP TO 20% OF ITS ASSETS, IN LOWER-RATED
SECURITIES, COMMONLY KNOWN AS "JUNK BONDS."  INVESTMENTS OF THIS TYPE INVOLVE
COMPARATIVELY GREATER RISKS, INCLUDING PRICE VOLATILITY AND RISK OF DEFAULT IN
THE PAYMENT OF INTEREST AND PRINCIPAL, THAN HIGHER-QUALITY SECURITIES.
ALTHOUGH THE STRATEGIC INCOME FUND'S SUBADVISER HAS THE ABILITY TO INVEST UP TO
100% OF THE PORTFOLIO'S ASSETS IN LOWER-RATED SECURITIES, THE PORTFOLIO'S
SUBADVISER DOES NOT ANTICIPATE INVESTING IN EXCESS OF 75% OF THE PORTFOLIO'S
ASSETS IN SUCH SECURITIES.  PURCHASERS SHOULD CAREFULLY ASSESS THE RISKS
ASSOCIATED WITH AN INVESTMENT IN THE STRATEGIC INCOME FUND.  SEE "RISK FACTORS
- -- HIGH YIELD SECURITIES."
     AN INVESTMENT IN THE MONEY MARKET FUND IS NEITHER INSURED NOR GUARANTEED
BY THE U.S. GOVERNMENT, AND THERE CAN BE NO ASSURANCE THAT THE MONEY MARKET
FUND WILL BE ABLE TO MAINTAIN A STABLE NET ASSET VALUE OF $1.00 PER SHARE.
SHARES OF THE FUND ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
ENDORSED BY, ANY BANK, AND THE SHARES ARE NOT FEDERALLY INSURED BY THE FEDERAL
DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD, OR ANY OTHER AGENCY.
     This Prospectus sets forth concisely the information about the Fund
that a prospective investor should know before making an investment decision.
Investors are encouraged to read this Prospectus and to retain it for future
reference.  Additional information about the Fund has been filed with the
Securities and Exchange Commission and is available upon request and without
charge by writing the Fund at the above address or calling (800) 872-8037 and

dated the date of this Prospectus (hereinafter "Statement of Additional
Information"). The Statement of Additional Information is incorporated by
reference into this Prospectus.
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE COMMISSION
OR ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
PROSPECTUS.  ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
                The date of this Prospectus is August 29, 1995.

                                    SUMMARY

THE FUND

     The Fund is an open-end, diversified, management investment company
organized as a business trust under the laws of the Commonwealth of
Massachusetts on September 28, 1988.

     NASL Financial Services, Inc. ("NASL Financial" or, in its capacity as the
Fund's investment adviser, the "Adviser") serves as the investment adviser and
distributor for the Fund.  NASL Financial is a wholly-owned subsidiary of the
Fund's sponsor, North American Security Life Insurance Company, based in
Boston, Massachusetts, which is part of The North American Group, a diversified
group of financial service companies based in Toronto, Canada currently with
over $16 billion in assets under management.

<TABLE>
     NASL Financial provides certain expense guarantees and administrative
services to the Fund and its shareholders pursuant to an investment advisory
contract (the "Advisory Agreement").  In addition, it contracts with and
compensates five investment subadvisers which provide portfolio management
services to the Fund (the "Subadviser(s)"):  Oechsle International Advisors,
L.P. ("Oechsle International"), Goldman Sachs Asset Management ("GSAM"),
Wellington Management Company ("Wellington Management"), J.P. Morgan Investment
Management, Inc. ("J.P. Morgan") and Salomon Brothers Asset Management Inc
("SBAM").  See "MANAGEMENT OF THE FUND."  The Subadvisers provide investment
management services to the various Portfolios of the Fund as shown in the

     NASL Financial also serves as the distributor of the Fund's shares and in
that role has entered into an exclusive promotional agent agreement with Wood
Logan Distributors, Inc. ("Wood Logan") to provide marketing services in
connection with the sales of Fund's shares.  See "PURCHASE OF SHARES --
Distribution Expenses."

     Each Portfolio has a stated specific investment objective, as set forth on
the cover of this Prospectus and described below.  See "INVESTMENT PORTFOLIOS."
There can be no assurance that any Portfolio will attain its investment
objective.  The Fund's annual report to shareholders, which is available
without charge upon request, contains a discussion of Fund performance.

     In addition to the risks inherent in any investment in securities, certain
Portfolios of the Fund are subject to particular risks associated with
investing in high yield securities, investing in foreign securities, investing
in warrants, lending portfolio securities, investing in when-issued securities
and engaging in various hedging and other strategic transactions (also referred
to as "derivative transactions").  See "RISK FACTORS."

CLASSES OF SHARES

     As of April 1, 1994, the Fund began offering three classes of shares in
each Portfolio ("Class A" shares, "Class B" shares and "Class C" shares) to the
general public with each class having a different sales charge structure and
expense level (the "Multiple Pricing System").  Each class has distinct
advantages and disadvantages for different investors, and investors may choose
the class that best suits their circumstances and objectives.  See "MULTIPLE
PRICING SYSTEM."

     CLASS A SHARES.  Purchases of Class A shares of less than $1 million are
offered for sale at net asset value per share plus a front end sales charge of
up to 4.75% (with the exception of Class A shares of the Money Market Fund,
which are offered without such a charge).  Purchases of Class A shares of $1
million or more made on or after May 1, 1995 are offered for sale at net asset
value without a front end 




<PAGE>   8

sales charge but subject to a contingent deferred sales charge ("CDSC") of 1%
of the dollar amount subject thereto during the first year after        
purchase.  The applicable percentage is assessed on an amount equal to the
lesser of the original purchase price or the redemption price of the shares
redeemed.  In addition, Class A shares are subject to a distribution fee of up
to .10% of their respective average annual net assets and a service fee of up
to .25% of their respective average annual net assets (with the exception of
Class A shares of the Money Market Fund, which bear no such fees, and Class A
shares of the National Municipal Bond Fund, which are subject to a service fee
of up to .15% of Class A average annual net assets and are not subject to any
distribution fee).

     CLASS B SHARES.  Class B shares are offered for sale for purchases of
$250,000 or less.  Class B shares are offered for sale at net asset value
without a front end sales charge but are subject to a CDSC of 5% of the dollar
amount subject thereto during the first and second year after purchase, and
declining by 1% each year thereafter to 0% after the sixth year.  The
applicable percentage is assessed on an amount equal to the lesser of the
original purchase price or the redemption price of the shares redeemed.  Class
B shares are also subject to a distribution fee of up to .75% of their
respective average annual net assets and a service fee of up to .25% of their
respective average annual net assets (with the exception of Class B shares of
the Money Market Fund, which bear no such fees).  Class B shares will
automatically convert to Class A shares of the same Portfolio six years after
purchase.

     CLASS C SHARES.  Class C shares are offered for sale for purchases of less
than $1 million, at net asset value without a front end sales charge .  Class C
shares purchased on or after May 1, 1995, are subject to a CDSC of 1% of the
dollar amount subject thereto during the first year after purchase.  Shares
purchased prior to May 1, 1995 are not subject to any CDSC upon redemption.
The applicable percentage is assessed on an amount equal to the lesser of the
original purchase price or the redemption price of shares redeemed.  Class C
shares are subject to a distribution fee of up to .75% of their respective
average annual net assets and a service fee of up to .25% of their respective
average annual net assets (with the exception of Class C shares of the Money
Market Fund, which bear no such fees).  Class C shares will automatically
convert to Class A shares of the same Portfolio ten years after purchase.

     The Fund implemented the Multiple Pricing System by reclassifying the
then existing shares of each Portfolio as shares of a particular class of each
such Portfolio.  This reclassification was effected in such a manner so that
the shares of each Portfolio outstanding at April 1, 1994 would be subject to
identical distribution and service fees both before and after the
reclassification.  Specifically, all outstanding shares of the Strategic
Income, Investment Quality Bond, U.S. Government Securities, National Municipal
Bond, and Money Market Funds were reclassified as Class A shares of each such
Portfolio, and all outstanding shares of the Global Growth, Growth, Growth and
Income and Asset Allocation Funds were reclassified as Class C shares of each
such Portfolio.

     For a discussion of factors to consider in selecting the most beneficial
class of shares for a particular investor, see "MULTIPLE PRICING
SYSTEM--Factors for Consideration."

     *Amounts listed under "Other expenses" and "Total fund operating expenses"
in the table above for each class of all Portfolios (except the International
Growth and Income Fund) are based on the application of expense limitations
applicable during the current fiscal year.  See "Advisory Arrangements" below.
Amounts listed under "Other expenses" and "Total fund operating expenses" for
the International Growth and Income Fund are based on estimates for current
fiscal year expenses.  To the extent that actual expenses are lower than the
expense limitations, "Other expenses" may vary as between classes of a
Portfolio as a result of certain class-specific incremental expenses being
allocated to a particular class of shares.
</TABLE>

     The amounts set forth under the caption "Shareholder Transaction Expenses"
are the maximum sales charges applicable to purchases of Fund shares.  Because
a portion of the 12b-1 fees payable by each class of shares is considered an
asset based sales charge by the National Association of Securities Dealers,
Inc. ("NASD"), long-term shareholders in each class of each Portfolio (other
than the Money

Market Fund) may pay more than the economic equivalent of the maximum front end
sales charges permitted by the NASD.  See "PURCHASE OF SHARES -- Class A Shares
- -- Reduced Sales Charges" in this Prospectus.

     The fees and expenses listed under the caption "Annual Fund Operating
Expenses" are described in this Prospectus under the captions "MANAGEMENT OF
THE FUND" and "PURCHASE OF SHARES -- Distribution Expenses."  The Advisory
Agreement and Distribution Plans operate to limit Total Fund Operating Expenses
to the amounts listed in the fee table for the remainder of the current fiscal
year.  Such contractual expense limits shall remain in effect from year to year
unless the Adviser notifies the Fund within 30 days of the end of the fiscal
year that it will not continue the limits.  See "MANAGEMENT OF THE FUND --
Advisory Agreement."  Total Fund Operating Expenses for the year ended October
31, 1994, absent reimbursement or waiver are set forth below under "Financial
Highlights."

EXAMPLE

     An investor would pay the following expenses on a $1,000 investment,
assuming (1) a 5% annual return and (2) redemption at the end of each time
period, with the exception of the lines marked "Class B No redemption" in which
case it is assumed that no redemption is made at the end of each time period:

     The foregoing Fee Table and Example are intended to assist investors in
understanding the various costs and expenses that investors in the Fund bear
directly and indirectly.  The example for the International Growth and Income
Fund does not include 5 and 10 year figures because it is a newly formed
Portfolio.  ACTUAL EXPENSES FOR ALL THE PORTFOLIOS MAY BE HIGHER OR LOWER THAN
THE AMOUNTS SHOWN IN THE FEE TABLE AND, CONSEQUENTLY, THE ACTUAL EXPENSES
INCURRED BY AN INVESTOR MAY BE GREATER (IN THE EVENT THE EXPENSE LIMITATIONS
ARE REMOVED) OR LESS THAN THE AMOUNTS SHOWN IN THE EXAMPLE.  MOREOVER, WHILE
THE EXAMPLE ASSUMES A 5% ANNUAL RETURN, THE PERFORMANCE OF EACH PORTFOLIO WILL
VARY AND MAY RESULT IN A RETURN GREATER OR LESS THAN 5%.

     investment objective of the new Asset Allocation Fund is substantially the same as that of the old Moderate Fund.  
     At the date of the merger, 3,567,198 shares of the old Moderate Fund with a per share value of $8.11 were decreased 
     to 2,891,572 shares with a per share value of $10.00, similar to a reverse stock split, and re-named as shares of 
     the new Asset Allocation Fund.  The historical per share data presented above has been adjusted as though a reverse 
     stock split had occurred at the beginning of the earliest period presented which results in fewer shares
     outstanding at a correspondingly higher net asset value per share.

                            MULTIPLE PRICING SYSTEM

     The Fund's Multiple Pricing System permits an investor to choose the
method of purchasing shares that is most beneficial given the amount of the
purchase and the length of time the investor expects to hold the shares.

     CLASS A SHARES.  Purchases of Class A shares of less than $1million are
offered for sale at net asset value per share plus a front end sales charge of
up to 4.75% payable at the time of purchase (with the exception of Class A
shares of the Money Market Fund, which are offered without such a charge).
Purchases of Class A shares of $1 million or more made on or after May 1, 1995
are offered for sale at net asset value without a front end sales charge but
subject to a contingent deferred sales charge ("CDSC") of 1% of the dollar
amount subject thereto during the first year after purchase.  See "MULTIPLE
PRICING SYSTEM-Contingent Deferred Sales Charge."  In addition, Class A shares
are subject to a distribution fee of up to .10% of their respective average
annual net assets and a service fee of up to .25% of their respective average
annual net assets (with the exception of Class A shares of the Money Market
Fund, which bear no such fees, and Class A shares of the National Municipal
Bond Fund, which are subject to a service fee of up to .15% of Class A average
annual net assets and are not subject to any distribution fee).  Certain
purchases of Class A shares qualify for reduced front end sales charges.  See
"PURCHASE OF SHARES -- Class A Shares -- Reduced Sales Charges" and "--
Distribution Expenses."

     CLASS B SHARES.  Class B shares are offered for sale for purchases of
$250,000 or less.   Class B shares are offered for sale at net asset value
without a front end sales charge, but are subject to a CDSC of 5% of the dollar
amount subject thereto during the first and second year after purchase, and
declining by 1% each year thereafter to 0% after the sixth year.  See "MULTIPLE
PRICING SYSTEM- Contingent Deferred Sales Charge."   In addition, Class B
shares are subject to a distribution fee of up to .75% of their respective
average annual net assets and a service fee of up to .25% of their respective
average annual net assets (with the exception of Class B shares of the Money
Market Fund, which bear no such fees).  The Class B shares enjoy the benefit of
permitting all of the investor's dollars to work from the time the investment
is made.  The higher ongoing distribution and service fees paid by Class B
shares will cause such shares to have a higher expense ratio and to pay lower
dividends than Class A shares.  See "PURCHASE OF SHARES -- Class B Shares" and
"-- Distribution Expenses."  Class B shares will automatically convert to Class
A shares six years after the end of the calendar month in which the
shareholder's order to purchase was accepted.  See "MULTIPLE PRICING SYSTEM --
Conversion Feature."

     CLASS C SHARES.  Class C shares are offered for purchases of less than $1
million, at net asset value without a front end sales charge.  Class C shares
purchased on or after May 1, 1995 are subject to a CDSC of 1% of the dollar
amount subject thereto during the first year after purchase.  Shares purchased
prior to May 1, 1995 are not subject to any CDSC upon redemption.  See
"MULTIPLE CLASS PRICING SYSTEM-Contingent Deferred Sales Charge."  Class C
shares are subject to a distribution fee of up to .75% of their respective
average annual net assets and a service fee of up to .25% of their respective
average annual net assets (with the exception of Class C shares of the Money
Market Fund, which bear no such fees).  Class C shares, like Class B shares,
enjoy the benefit of permitting all of the investor's dollars to work from the
time the investment is made.  The higher ongoing distribution and service fees
paid by Class C shares will cause such shares to have a higher expense ratio
and to pay lower dividends than Class A shares.  See "PURCHASE OF SHARES --
Class C Shares" and "--Distribution Expenses."   Class C shares will
automatically convert to Class A shares ten years after the end of the calendar
month in which the shareholder's order to purchase was accepted.  See "MULTIPLE
PRICING SYSTEM -- Conversion Feature."

     CONTINGENT DEFERRED SALES CHARGE.  Purchases of $1 million or more of
Class A shares made on or after May 1, 1995 are subject to a CDSC of 1% if
redeemed within one year of purchase; purchases of Class B shares are subject
to a CDSC of 5% during the first and second year after purchase declining by 1%
each year thereafter to 0% after the sixth year; and Class C shares purchased
on or after May 1, 1995 are subject to a CDSC of 1% if redeemed within one year
of purchase.  The applicable percentage is assessed on an amount equal to the
lesser of the original purchase price or the redemption price of the shares
redeemed.  The CDSC is not applicable with respect to redemption of shares of
the Money Market Fund which were initially purchased as such and which were
never exchanged for shares of the same class of another Portfolio.  However, in
the case of shares of the Money Market Fund which were obtained through an
exchange, such shares are subject to any applicable CDSC due at redemption.
Similarly, shares initially purchased as shares of the Money Market Fund which
are subsequently exchanged for shares of the same class of other Portfolios
will be subject to any applicable CDSC due at redemption.  See "SHAREHOLDER
SERVICES -- Exchange Privilege."

     CONVERSION FEATURE.  Class B shares and Class C shares will automatically
convert to Class A shares six years and ten years, respectively, after the end
of the calendar month in which the shareholder's order to purchase was accepted
and will thereafter no longer be subject to the higher distribution and service
fees.  Such conversion will be on the basis of the relative net asset values
per share, without the imposition of any sales charge, fee or other charge.
The purpose of the conversion feature is to relieve the holders of Class B
shares and Class C shares from most of the burden of distribution-related
expenses at such time as when the shares have been outstanding for a duration
sufficient for the Fund's distributor, NASL Financial Services, Inc. (in such
capacity, the "Distributor"), to have been substantially compensated for
distribution-related expenses incurred in connection with Class B shares or
Class C shares, as the case may be.  Accordingly, Class B and Class C shares of
the Money Market Fund do not convert to Class A shares of the Money Market Fund
at any time, as shares of all classes of the Money Market Fund do not bear any
distribution or service fees.  In addition, because Class B and Class C shares
of the Money Market Fund are not subject to any distribution or service fees,
the applicable conversion period is tolled for any period

                                       21

<PAGE>   28

of time in which Class B or Class C shares are held in that Portfolio.  For
example, if Class B shares of a Portfolio other than the Money Market Fund are
exchanged for Class B shares of the Money Market Fund two years after purchase
and are subsequently exchanged one year later for Class B shares of a Portfolio
other than the Money Market Fund, the one year of ownership in the Money Market
Fund does not count in the determination of the time of conversion to Class A
shares.

     For purposes of the conversion of Class B and Class C shares to Class A
shares, shares purchased through the reinvestment of dividends and
distributions paid on Class B shares or Class C shares, as the case may be, in
a shareholder's Fund account will be considered to be held in a separate
sub-account.  Each time any Class B shares or Class C shares in the
shareholder's Fund account (other than those in the sub-account) convert to
Class A shares, a pro rata portion of the Class B shares or Class C shares, as
the case may be, in the sub-account will also convert to Class A shares.

     The conversion of Class B shares to Class A shares and the conversion of
Class C shares to Class A shares are both subject to the continuing
availability of a ruling of the Internal Revenue Service that payment of
different dividends on Class A shares and Class B shares, and on Class A shares
and Class C shares, does not result in the Portfolios' dividends or
distributions constituting "preferential dividends" under the Internal Revenue
Code of 1986, as amended (the "Code"), and the continuing availability of an
opinion of counsel to the effect that the conversion of shares does not
constitute a taxable event under Federal income tax law.  The conversion of
Class B shares and Class C shares may be suspended if such an opinion is no
longer available.  In that event, no further conversions of Class B shares or
Class C shares would occur, and those shares might continue to be subject to
higher distribution and service fees for an indefinite period which may extend
beyond the period ending six years or ten years, respectively, after the end of
the calendar month in which the shareholder's order to purchase was accepted.

     FACTORS FOR CONSIDERATION.  The Fund's Multiple Pricing System is designed
to provide investors with the option of choosing the class of shares which is
best suited to their individual circumstances and objectives.  The different
sales charges, distribution and service fees and conversion features applicable
to each class, as outlined above, should all be taken into consideration by
investors in making the determination of which alternative is best suited for
them.  To assist investors in evaluating the costs and benefits of purchasing
shares of each class, the information provided above under the caption "Fee
Table and Example" sets forth the charges applicable to each class of shares
and illustrates an example of a hypothetical investment in each class of shares
of each Portfolio.

     There are several key distinctions among the classes of shares that
investors should understand and evaluate in comparing the options presented by
the Multiple Pricing System.  Class A shares are subject to lower distribution
and service fees than are Class B and Class C shares, and, accordingly, pay
correspondingly higher dividends per share.  However, because for purchases of
less than $1 million of Class A shares a front end sales charge is deducted at
the time of purchase, investors purchasing Class A shares do not have all of
their funds invested initially and, therefore, initially own fewer shares than
they would own if they had invested the identical sum in Class B shares or
Class C shares instead.  In addition, Class C shares are subject to the same
ongoing distribution and service fees as Class B shares but are subject to a
CDSC for a shorter period of time (one year as opposed to six years) than Class
B shares.  However, Class B shares convert to Class A shares, and lower ongoing
distribution and service fees, in a shorter time frame than do Class C shares.

     In light of these distinctions among the classes of shares, investors
should weigh such factors as (i) whether they qualify for a reduced front end
sales load for a purchase of Class A shares; (ii) whether, at the time of
purchase, they anticipate being subject to a CDSC upon redemption if they
purchase Class A shares (purchases of $1 million or more), Class B shares or
Class C shares; (iii) the differential in the relative amounts that would be
paid during the anticipated life of investments (which are made at the same
time and in the same amount) in each class which are attributable to (a) the
front end sales charge (for purchases of less than $1 million) and any
applicable CDSC (for purchases of $1 million or more) and accumulated
distribution and service fees payable with respect to Class A shares and (b)
the accumulated distribution and service fees (and any applicable CDSC) payable
with respect to Class B shares or Class C shares prior to their conversion to
Class A shares; and (iv) to what extent the differential referred to above
might be offset by the higher yield of Class A shares.  Investors should also
weigh these considerations against the fact that the higher continued
distribution and service fees associated with Class B shares and Class C shares
will be offset to the extent any return is realized on the additional funds
initially invested and that there can be no assurance as to the return, if any,
which will be realized on such additional funds.  Class A shares are, in
general, the most beneficial for the investor who qualifies for reduced front
end sales charges, as described herein under "PURCHASE OF SHARES -- Class A
Shares." For this reason, Class B shares are not offered for purchases in
excess of $250,000 and Class C shares are not offered for purchases of $1
million or more.  Investors should consult their investment representative for
assistance in evaluating the relative benefits of the different classes of
shares.

     The distribution and shareholder service expenses incurred by the
Distributor in connection with the sale of shares will be paid, in the case of
Class A shares (purchases of less than $1 million), from the proceeds of front
end sales charges and ongoing distribution and service fees and in the case of
Class A shares (purchases of $1 million or more), Class B shares and Class C
shares, from the proceeds of CDSCs and ongoing distribution and service fees.
Sales personnel of broker-dealers distributing the Fund's shares and any other
persons entitled to receive compensation for selling or servicing the Fund's
shares may receive different compensation for selling or servicing one 
                                       22

class of shares over another.  INVESTORS SHOULD UNDERSTAND THAT FRONT
END SALES CHARGES, CDSCS AND ONGOING DISTRIBUTION AND SERVICE FEES ARE ALL
INTENDED TO COMPENSATE THE DISTRIBUTOR FOR DISTRIBUTION SERVICES.  See
"PURCHASE OF SHARES -- Distribution Expenses."

     Dividends paid by the Fund with respect to each class of shares will be
calculated in substantially the same manner at the same time on the same day,
except that distribution and service fees and any other costs specifically
attributable to a particular class of shares will be borne solely by the
applicable class.  See "GENERAL INFORMATION -- Dividends and Distributions."
Shares of the Fund may be exchanged for shares of the same class of any other
Portfolio, but not for shares of other classes of any Portfolio.  See
"SHAREHOLDER SERVICES -- Exchange Privilege."

     The Trustees of the Fund have determined that currently no conflict of
interest exists between the classes of shares.  On an ongoing basis, the
Trustees of the Fund, pursuant to their fiduciary duties under the Investment
Company Act of 1940 (the "1940 Act") and state laws, will seek to ensure that
no such conflict arises.

                             INVESTMENT PORTFOLIOS

     Each Portfolio has a stated investment objective which it pursues through
separate investment policies.  The differences in objectives and policies among
the Portfolios can be expected to affect the return of each Portfolio and the
degree of market and financial risk to which each Portfolio is subject.

     The investment objective of each Portfolio represent fundamental policies
of each such Portfolio and may not be changed without the approval of the
holders of a majority of the outstanding shares of the Portfolio.  Except for
certain investment restrictions, the policies by which a Portfolio seeks to
achieve its investment objectives may be changed by the Trustees of the Fund
without the approval of the shareholders.

     The following is a description of the investment objective and policies of
each Portfolio.  More complete descriptions of the money market instruments in
which each Portfolio may invest and of the options, futures and currency
transactions that certain Portfolios may engage in are set forth in the
Statement of Additional Information.  With regard to fixed income securities
there is an inverse relationship between changes in the direction of interest
rates and the market value of the securities.  A more complete description of
the debt security ratings used by the Fund assigned by Moody's Investors
Service, Inc. ("Moody's"), Standard and Poor's Ratings Group ("Standard &
Poor's" or "S&P") or Fitch Investors Service, Inc. ("Fitch") is included in
Appendix I to this Prospectus.

GLOBAL GROWTH FUND

     The investment objective of the Global Growth Fund is long term capital
appreciation.  Oechsle International manages the Global Growth Fund and will
pursue this objective by investing the assets of the Global Growth Fund
primarily in a global portfolio of equity securities and securities convertible
into or exercisable for equity securities.

     Under normal circumstances, at least 80% of the assets of the Global
Growth Fund will be invested in a global portfolio of equity securities and
securities convertible into or exercisable for equity securities.  There is no
limitation on the percentage of the Global Growth Fund's assets that may be
invested in any one country, although the Global Growth Fund will maintain an
exposure to the equity markets in at least three countries under normal
circumstances (one of which may be the United States).  When Oechsle
International sees selected opportunities for long-term capital appreciation in
the fixed-income markets, up to 20% of the assets of the Global Growth Fund may
be invested in fixed-income securities.  Such opportunities may include
situations where there is expected to be a substantial decline in interest
rates in a particular country or when a substantial strengthening of a
country's currency relative to the U.S. dollar is anticipated, but the equity
markets in such country appear unattractive.  The Portfolio may also, under
normal circumstances, maintain a reserve of cash equivalents pending the
selection of appropriate investments and to meet redemption requests.  Cash
reserves are generally held in short-term U.S. Government instruments, although
non-U.S. Government securities may be held for this purpose from time to time.

     When Oechsle International foresees unusual market risks, the Global
Growth Fund may temporarily take a defensive position to attempt to preserve
the value of the Portfolio's assets and to reduce portfolio volatility by
investing substantially all of such assets in fixed-income securities or cash
and cash equivalents.  Similarly, if Oechsle International foresees unusual
market risks in the international markets, the Global Growth Fund may take a
temporary defensive position by investing substantially all of its assets in
U.S. securities.  In either case, during periods when the Global Growth Fund
adopts a defensive position, it may not achieve its objective of long-term
capital appreciation.

     Oechsle International seeks to achieve the Global Growth Fund's investment
objective of long-term capital appreciation by selecting equity investments
based on a two-pronged approach of (i) choosing a limited group of countries
with strong and stable national financial markets with total market
capitalization in excess of $5 billion, and (ii) identifying a select group of
companies in such countries with

                                       23

<PAGE>   30

attractive investment potential and market capitalization of $200 million or
more.  The following is a brief description of the Oechsle International
two-pronged investment approach.

     COUNTRY SELECTION.  The Global Growth Fund will seek long-term capital
appreciation by emphasizing markets identified as attractive.  While the Global
Growth Fund is permitted to concentrate its investments in as few as three
countries, it is Oechsle International's intention under normal circumstances
to attempt to reduce overall portfolio risk through diversification of
investments across a limited group of national markets.  Diversification
provides a prudent method of reducing risk.  Opportunities for global investing
have broadened in recent years.  For example, in 1980 the U.S. stock market
capitalization represented approximately 70% of the total world stock market
capitalization and by 1990 such share had fallen to approximately 30%.

     Investments generally will be limited to companies in countries where
total market capitalization exceeds $5 billion.  The Global Growth Fund's focus
will normally be on the largest, most liquid international equity markets
including, but not limited to, the United States, Japan, the United Kingdom,
the Federal Republic of Germany, Canada, France and Italy.

     SECURITY SELECTION.  Investments will generally be made in companies with
market capitalizations of at least $200 million.  Oechsle International focuses
its research effort on exchange listed U.S. companies and a universe of
approximately 1,000 non-U.S. companies, most of which are included in either
the Morgan Stanley Capital International Europe, Australia and Far East Index
or other major international indices.  The Global Growth Fund intends to
purchase and hold securities for long-term capital appreciation and does not
expect to trade for short-term gain.

     As stated above, the Global Growth Fund may invest up to 20% of its assets
in fixed-income securities to attempt to take advantage of selected
opportunities in the debt markets for long-term capital appreciation.  The
types of fixed-income securities in which the Global Growth Fund may invest
are: (i) debt obligations issued or guaranteed by the U.S. Government or one of
its agencies or political subdivisions; (ii) debt obligations issued or
guaranteed by a foreign sovereign government or one of its agencies or
political subdivisions; (iii) debt obligations issued or guaranteed by
supranational organizations (e.g., the International Bank for Reconstruction
and Development (the "World Bank"), the European Coal and Steel Community, the
Asian Development Bank and the Inter-American Development Bank) that are
assigned within the four highest bond ratings by Moody's or Standard & Poor's
or, if not rated, that are of equivalent investment quality as determined by
Oechsle International pursuant to guidelines established by the Trustees; and
(iv) corporate debt securities assigned within the three highest bond ratings
by Moody's or Standard & Poor's or, if not rated, that are of equivalent
investment quality as determined by Oechsle International pursuant to
guidelines established by the Trustees of the Fund.

     While bonds carrying the fourth highest quality rating ("Baa" by Moody's
or "BBB" by Standard & Poor's) are considered as investment grade and are
viewed to have adequate capacity for payment of principal and interest,
investments in such securities involve a higher degree of risk than that
associated with investments in debt securities in the higher rating categories
and such bonds lack outstanding investment characteristics and have speculative
characteristics.  For example, 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 bonds.  While the
Global Growth Fund will not invest in corporate debt securities rated below "A"
by Moody's or Standard & Poor's or debt obligations of supranational
organizations rated below "Baa" by Moody's or "BBB" by Standard & Poor's, it is
not required to dispose of securities that may be downgraded below such
ratings.

     The Global Growth Fund will be subject to special risks as a result of its
ability to invest up to 100% of its assets in foreign securities.  These risks
are described under the caption "RISK FACTORS -- Foreign Securities" in this
Prospectus.  Moreover, substantial investments in foreign securities may have
adverse tax implications as described under "GENERAL INFORMATION -- Taxes" in
this Prospectus.  The ability to diversify its investments among the equity
markets in different countries may, however, reduce the overall level of market
risk to the extent it may reduce the Global Growth Fund's exposure to a single
market.

     USE OF HEDGING AND OTHER STRATEGIC TRANSACTIONS.  The Global Growth Fund
is currently authorized to use all of the various investment strategies
referred to under "RISK FACTORS -- Hedging and Other Strategic Transactions
(also referred to derivative transactions)."  A "derivative" is generally
defined as an instrument whose value is based upon, or derived from, some
underlying index, reference rate (e.g., interest rate or currency exchange
rate, security, commodity or other asset).  It is not presently anticipated
that any of these strategies will be used to a significant degree by the
Portfolio.  The Statement of Additional Information contains a description of
these strategies and of certain risks associated therewith.

                                       24

<PAGE>   31
GROWTH FUND

     The investment objective of the Growth Fund is long-term growth of
capital.  Growth of income may accompany growth of capital.  GSAM manages the
Growth Fund which will seek to attain its objective by investing under normal
circumstances at least 65% of its total assets in equity securities, consisting
of common or preferred stocks, including options and warrants.

     The Growth Fund will invest primarily in securities listed on national
securities exchanges and securities traded in the "over-the-counter" market.
Under normal market conditions, the Growth Fund may invest up to 35% of its
total assets in government securities, short-term debt securities, money market
instruments, cash or investment grade bonds (i.e., rated within the four
highest bond ratings assigned by Moody's or S&P or, if not rated, determined to
be of comparable quality by GSAM).  Government securities and investment grade
bonds may include mortgage backed securities, asset backed securities and
municipal securities.  See "U.S. Government Securities Fund" below and "Other
Instruments" in the Statement of Additional Information for a description of
these securities.  When in GSAM's opinion market or economic conditions warrant
a temporary defensive posture, the Growth Fund may place any portion of its
assets in these types of non-equity assets.  The lowest rated category of
investment grade bonds have some speculative characteristics and instruments
with such ratings are subject to greater fluctuations in value than more highly
rated instruments as economic conditions change.  The Growth Fund is not
required to dispose of such instruments in the event they are downgraded below
investment grade.

     The Growth Fund will be subject to certain risks as a result of its
ability to invest up to 20% of its assets in foreign securities.  These risks
are described under the caption "RISK FACTORS -- Foreign Securities" in this
Prospectus.  Moreover, substantial investments in foreign securities may have
adverse tax implications as described under "GENERAL INFORMATION -- Taxes" in
this Prospectus.

     USE OF HEDGING AND OTHER STRATEGIC TRANSACTIONS.  The Growth Fund is
currently authorized to use all of the various investment strategies referred
to under "RISK FACTORS -- Hedging and Other Strategic Transactions."  The
Statement of Additional Information contains a description of these strategies
and of certain risks associated therewith.

GROWTH AND INCOME FUND

     The investment objective of the Growth and Income Fund is to provide
long-term growth of capital and income consistent with prudent investment risk.

     Wellington Management manages the Growth and Income Fund and seeks to
achieve the Portfolio's objective by investing primarily in a diversified
portfolio of common stocks of U.S. issuers which Wellington Management believes
are of high quality.  Wellington Management believes that high quality is
evidenced by a leadership position within an industry, a strong or improving
balance sheet, relatively high return on equity, steady or increasing dividend
payout, and strong management skills.  The Growth and Income Fund's investments
will primarily emphasize dividend paying stocks of larger companies.  The
Growth and Income Fund may also invest in securities convertible into or which
carry the right to buy common stocks, including those convertible securities
issued in the Euromarket; preferred stocks; and marketable debt securities of
domestic issuers and of foreign issuers (payable in U.S. dollars), if such
marketable debt securities of domestic issuers and foreign issuers are rated at
the time of purchase "A" or better by Moody's or S&P or, if unrated, deemed to
be of equivalent quality in Wellington Management's judgment.  When market or
financial conditions warrant a temporary defensive posture, the Growth and
Income Fund may, in order to reduce risk and achieve attractive total
investment return, invest in securities which are authorized for purchase by
the Investment Quality Bond Fund or the Money Market Fund.  The Subadviser
expects that under normal market conditions, the Growth and Income Fund's
portfolio will consist primarily of equity securities.

     Investments will be selected on the basis of fundamental analysis to
identify those securities that, in Wellington Management's judgment, provide
the potential for long-term growth of capital and income.  Fundamental analysis
involves assessing a company and its business environment, management, balance
sheet, income statement, anticipated earnings and dividends and other related
measures of value.  When selecting securities of issuers domiciled outside of
the United States, Wellington Management will also monitor and evaluate the
economic and political climate and the principal securities markets of the
country in which each company is located.

     The Growth and Income Fund will invest primarily in securities listed on
national securities exchanges, but from time to time it may also purchase
securities traded in the "over-the-counter" market.

     The Growth and Income Fund will be subject to certain risks as a result of
its ability to invest up to 20% of its assets in foreign securities.  These
risks are described under the caption "RISK FACTORS -- Foreign Securities" in
this Prospectus.  Moreover, substantial investments in foreign securities may
have adverse tax implications as described under "GENERAL INFORMATION -- Taxes"
in this Prospectus.

     USE OF HEDGING AND OTHER STRATEGIC TRANSACTIONS.  The Growth and Income
Fund is currently authorized to use all of the various investment strategies
referred to under "RISK FACTORS -- Hedging and Other Strategic Transactions."
However, it is not presently anticipated that any of these strategies will be
used to a significant degree by the Portfolio.  The Statement of Additional
Information contains a description of these strategies and of certain risks
associated therewith.

INTERNATIONAL GROWTH AND INCOME FUND

     The investment objective of the International Growth and Income Fund is to
seek long-term growth of capital and income.  The Portfolio is designed for
investors with a long-term investment horizon who want to take advantage of
investment opportunities outside the United States.

     J.P. Morgan manages the International Growth and Income Fund and will seek
to achieve the Portfolio's investment objective by investing, under normal
circumstances, at least 65% of its total assets in equity securities of foreign
issuers, consisting of common stocks and other securities with equity
characteristics such as preferred stock, warrants, rights and convertible
securities.  The Portfolio will focus primarily on the common stock of
established companies based in developed countries outside the United States.
Such investments will be made in at least three foreign countries.  For this
purpose, a developed country is any country included in the MSCI World Index.
The countries currently included in this Index are:  Australia, Austria,
Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy,
Japan, Malaysia, Netherlands, New Zealand, Norway, Singapore, Spain, Sweden,
Switzerland, United Kingdom and the U.S.  The Portfolio 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 certain
restricted or unlisted securities.  See "RISK FACTORS -- Foreign Securities."
Under normal circumstances, the International Growth and Income Fund expects to
invest primarily in equity securities.  However, the Portfolio may invest up to
35% of its assets in debt obligations of corporate, sovereign issuers or
supranational organizations rated A or higher by Moody's or S&P, or if unrated,
of equivalent credit quality as determined by the Subadviser.  See "Strategic
Income Fund" below for additional information on supranational organizations.
Under normal circumstances, the Portfolio will be invested approximately 85% in
equity securities and 15% in fixed income securities.  J.P. Morgan may allocate
the Portfolio's investment in these asset classes in a manner consistent with
the Portfolio's investment objective and current market conditions.  Using a
variety of analytical tools, J.P. Morgan assesses the relative attractiveness
of each asset class and determines an optimal allocation between them.  Yields
on non-U.S. equity securities tend to be lower than those on equity securities
of U.S. issuers.  Therefore, current income from the Portfolio may not be as
high as that available from a portfolio of U.S. equity securities.

     In pursuing the International Growth and Income Fund's objective, J.P.
Morgan will actively manage the assets of the Portfolio through country
allocation and stock valuation and selection.  Based on fundamental research,
quantitative valuation techniques and experienced judgment, J.P. Morgan uses a
structured decision-making process to allocate the Portfolio primarily across
the developed countries of the world outside the United States.  This universe
is typically represented by the Morgan Stanley Europe, Australia and Far East
Index (the "EAFE Index").

     Using a dividend discount model and based on analysts' industry expertise,
securities within each country are ranked within industry sectors according to
their relative value.  Based on this valuation, J.P. Morgan selects the
securities which appear the most attractive for the Portfolio.  J.P. Morgan
believes that under normal market conditions, industrial sector weightings
generally will be similar to those of the EAFE index.

     Finally, J.P. Morgan actively manages currency exposure, in conjunction
with country and stock allocation, in an attempt to protect and possibly
enhance the International Growth and Income Fund's market value.  Through the
use of forward foreign currency exchange contracts, J.P. Morgan will adjust the
Portfolio's foreign currency weightings to reduce its exposure to currencies
that the Subadviser deems unattractive and, in certain circumstances, increase
exposure to currencies deemed attractive, as market conditions warrant, based
on fundamental research, technical factors and the judgment of a team of
experienced currency managers.

     The International Growth and Income Fund intends to manage its portfolio
actively in pursuit of its investment objective.  The Portfolio does not expect
to trade in securities for short-term profits; however, when circumstances
warrant, securities may be sold without regard to the length of time held.  See
"GENERAL INFORMATION -- Taxes."  To the extent the Portfolio engages in
short-term trading, it may incur increased transaction costs.

     The International Growth and Income Fund may also invest in securities on
a when-issued or delayed delivery basis, enter into repurchase and reverse
repurchase agreements, loan its portfolio securities and purchase certain
privately placed securities.  See "RISK FACTORS."

     The International Growth and Income Fund may make money market investments
pending other investments or settlement or for liquidity purposes.  In
addition, when J.P. Morgan believes that investing for defensive purposes is
appropriate, such as during periods of unusual or unfavorable market or
economics conditions, up to 100% of the Portfolio's assets may be temporarily
invested in money market instruments.  The money market investments permitted
for the Portfolio include obligations of the U.S. Government and its agencies
and

                                       26

<PAGE>   33

instrumentalities, other debt securities, commercial paper, bank obligations
and repurchase agreements, as described below under "Money Market Fund."

     The International Growth and Income Fund will be subject to special risks
as a result of its ability to invest up to 100% of its assets in foreign
securities.  These risks are described under the caption "RISK FACTORS --
Foreign Securities" in this Prospectus.  The ability to diversify its
investments among the equity markets of different countries may, however,
reduce the overall level of market risk to the extent it may reduce the
Portfolio's exposure to a single market.  Moreover, substantial investments in
foreign securities may have adverse tax implications as described under
"GENERAL INFORMATION -- Taxes" in this Prospectus.

     USE OF HEDGING AND OTHER STRATEGIC TRANSACTIONS.  The International Growth
and Income Fund is currently authorized to use all of the various investment
strategies referred to under "RISK FACTORS -- Hedging and Other Strategic
Transactions".  With the exception of currency transactions, however, it is not
presently anticipated that any of these strategies will be used to a
significant degree by the Portfolio.  The Statement of Additional Information
contains a description of these strategies and of certain risks associated
therewith.

ASSET ALLOCATION FUND

     The investment objective of the Asset Allocation Fund is to obtain the
highest total return consistent with a moderate level of risk tolerance. The
Asset Allocation Fund is designed for:

     * The investor who wants to maximize total return potential, but lacks the
time, temperament or expertise to do so effectively;

     * The investor who does not want to monitor the financial markets in order
to make periodic exchanges among Portfolios;

     * The investor who wants the opportunity to improve on the return of an
income-oriented investment program, but wants to take advantage of the risk
management features of the Asset Allocation Fund; and

     * Retirement program fiduciaries who have a responsibility to limit risk
in a meaningful way, while seeking the highest potential total return.

     The Asset Allocation Fund may invest in a combination of equity,
fixed-income and money market securities.  GSAM manages the Asset Allocation
Fund and the amount of the Portfolio's assets invested in each category of
securities is dependent upon GSAM's judgment as to what percentage of the
Portfolio's assets in each category will contribute to the limitation of risk
and the achievement of its investment objective.  GSAM reserves complete
discretion to determine the allocations among the categories of securities.

     GSAM attempts to limit the maximum amount of decline in value the
Portfolio incurs under very adverse market conditions to a moderate level of
risk tolerance, defined as a 10% decline over a twelve month period.  Very
adverse market conditions are defined as a substantial increase in long-term
interest rates accompanied by a similarly substantial decline in one or more
commonly-followed stock market indices over a twelve month period.  Of course,
GSAM cannot predict with certainty when very adverse market conditions will
arise. Consequently, GSAM must manage the Asset Allocation Fund under all
market conditions with a view toward limiting risk and Portfolio decline should
very adverse market conditions arise. GSAM will invest the Asset Allocation
Fund's assets to attempt to give the Portfolio a substantial participation in
favorable equity and bond markets, although the expected total return will not
necessarily exceed the best returns available from either of those markets.
When market conditions deteriorate (and the probability of very adverse market
conditions rises), GSAM will give greater emphasis to fixed-income securities
and money market instruments in an effort to limit overall declines in
portfolio value. There can be no assurance that actual declines in portfolio
value will not exceed the 10% limitation set forth above.

     The types and characteristics of equity securities to be purchased by the
Asset Allocation Fund are set forth above in the discussion of investment
objectives and policies for the Growth Fund; the types and characteristics of
the fixed-income securities to be purchased are set forth below in the
discussion of the investment objective and policies for the Investment Quality
Bond and U.S. Government Securities Funds (the Asset Allocation Fund is not,
however, authorized to invest in non-investment grade securities as is the
Investment Quality Bond Fund); and the types and characteristics of the money
market securities to be purchased are set forth below in the discussion of the
investment objective and policies of the Money Market Fund. In addition to
these securities, the Asset Allocation Fund may also invest in municipal
obligations.  See "National Municipal Bond Fund" below for a description of
these securities.  Potential investors should review the discussions therein
when considering an investment in shares of the Asset Allocation Fund.

     The Asset Allocation Fund will be subject to certain risks as a result of
its ability to invest up to 20% of its assets in foreign securities.  These
risks are described under the caption "RISK FACTORS -- Foreign Securities" in
this Prospectus.  Moreover, substantial

                                       27

<PAGE>   34

investments in foreign securities may have adverse tax implications as
described under "GENERAL INFORMATION -- Taxes" in this Prospectus.

     USE OF HEDGING AND OTHER STRATEGIC TRANSACTIONS.  The Asset Allocation
Fund is currently authorized to use all of the various investment strategies
referred to under "RISK FACTORS -- Hedging and Other Strategic Transactions."
The Statement of Additional Information contains a description of these
strategies and of certain risks associated therewith.

STRATEGIC INCOME FUND

     The investment objective of the Strategic Income Fund is to seek a high
level of total return consistent with preservation of capital.

     The Strategic Income Fund seeks to achieve its objective by giving its
Subadviser, SBAM, broad discretion to deploy the Strategic Income Fund's assets
among certain segments of the fixed-income market as SBAM believes will best
contribute to the achievement of the Portfolio's objective.  At any point in
time, SBAM will deploy the Portfolio's assets based on SBAM's analysis of
current economic and market conditions and the relative risks and opportunities
present in the following market segments:  U.S. Government obligations,
investment grade domestic corporate debt, high yield corporate debt securities,
mortgage-backed securities and investment grade and high yield international
debt securities.  SBAM is an affiliate of Salomon Brothers Inc ("SBI"), and in
making investment decisions is able to draw on the research and market
expertise of SBI with respect to fixed-income securities.  In addition, SBAM
has entered into a subadvisory consulting agreement with its London based
affiliate, Salomon Brothers Asset Management Limited ("SBAM Limited") pursuant
to which SBAM Limited will provide certain advisory services to SBAM relating
to currency transactions and investments in non-dollar denominated debt
securities for the benefit of the Portfolio.

     In pursuing the Strategic Income Fund's investment objective, the
Portfolio reserves the right to invest without limitation in lower-rated
securities, commonly known as "junk bonds."  (i.e., rated "B" or below by
Moody's (Moody's lowest rating is C, See Appendix I.) or "BB" or below by
S&P(S&P lowest rating is D, see Appendix I.), or if unrated, of comparable
quality as determined by Wellington Management).  No minimum rating standard is
required for a purchase by the Portfolio.  Investments of this type involve
comparatively greater risks, including price volatility and risk of default in
the payment of interest and principal, than higher-quality securities.
Although the Portfolio's Subadviser has the ability to invest up to 100% of the
Portfolio's assets in lower-rated securities, the Portfolio's Subadviser does
not anticipate investing in excess of 75% of the Portfolio's assets in such
securities.  Purchasers should carefully assess the risks associated with an
investment in this Portfolio.  See "RISK FACTORS -- High Yield Securities."

     SBAM will determine the amount of assets to be allocated to each type of
security in which it invests based on its assessment of the maximum level of
total return that can be achieved from a portfolio which is invested in these
securities without incurring undue risks to principal value.  In making this
determination, SBAM will rely in part on quantitative analytical techniques
that measure relative risks and opportunities of each type of security based on
current and historical economic, market, political and technical data for each
type of security, as well as on its own assessment of economic and market
conditions both on a global and local (country) basis.  In performing
quantitative analysis, SBAM will employ prepayment analysis and option adjusted
spread technology to evaluate mortgage securities, mean variance optimization
models to evaluate international debt securities, and total rate of return
analysis to measure relative risks and opportunities in other fixed-income
markets.  Economic factors considered will include current and projected levels
of growth and inflation, balance of payment status and monetary policy.  The
allocation of assets to international debt securities will further be
influenced by current and expected currency relationships and political and
sovereign factors.  The Portfolio's assets may not always be allocated to the
highest yielding securities if SBAM feels that such investments would impair
the Portfolio's ability to preserve shareholder capital.  SBAM will
continuously review this allocation of assets and make such adjustments as it
deems appropriate.  The Portfolio does not plan to establish a minimum or a
maximum percentage of the assets which it will invest in any particular type of
fixed-income security.

     In addition, SBAM will have discretion to select the range of maturities
of the various fixed-income securities in which the Portfolio invests.  Such
maturities may vary substantially from time to time depending on economic and
market conditions.

     The types and characteristics of the U.S. Government obligations,
mortgage-backed securities, investment grade corporate debt securities and
investment grade international debt securities to be purchased by the Portfolio
are set forth in the discussion of investment objectives and policies for the
Investment Quality Bond and U.S. Government Securities Funds, and in the
section entitled "OTHER INSTRUMENTS" in the Statement of Additional
Information; and the types and characteristics of the money market securities
to be purchased are set forth in the discussion of investment objectives and
policies of the Money Market Fund.  Potential investors should review the
discussion therein in considering an investment in shares of the Strategic
Income Fund.  As described below, the Strategic Income Fund may also invest in
high yield domestic and foreign debt securities.

     The Strategic Income Fund may also invest in debt obligations issued or
guaranteed by a foreign sovereign government or one of its agencies or
political subdivisions and debt obligations issued or guaranteed by
supranational organizations.  Supranational entities include international
organizations designated or supported by governmental entities to promote
economic reconstruction or development and international banking institutions
and related government agencies.  Examples include the International Bank for
Reconstruction and

                                       28

<PAGE>   35

Development (the "World Bank"), the European Coal and Steel Community, the
Asian Development Bank and the Inter-American Development Bank.  Such
supranational issued instruments may be denominated in multi-national currency
units.

     The Strategic Income Fund currently intends to invest substantially all of
its assets in fixed-income securities.  In order to maintain liquidity,
however, the Strategic Income Fund may invest up to 20% of its assets in
high-quality short-term money market instruments.  If at some future date, in
the opinion of SBAM, adverse conditions prevail in the market for fixed-income
securities, the Strategic Income Fund for temporary defensive purposes may
invest its assets without limit in high-quality short-term money market
instruments.

     As discussed above, the Strategic Income Fund may invest in U.S.
dollar-denominated securities issued by domestic issuers that are rated below
investment grade or, if unrated, determined by SBAM to be of comparable
quality.  Although SBAM does not anticipate investing in excess of 75% of the
Strategic Income Fund's assets in domestic and developing country debt
securities that are rated below investment grade, the Strategic Income Fund may
invest a greater percentage in such securities when, in the opinion of SBAM,
the yield available from such securities outweighs their additional risks.  By
investing a portion of the Strategic Income Fund's assets in securities rated
below investment grade, as well as through investments in mortgage securities
and international debt securities, as described below, SBAM expects to provide
investors with a higher yield than a high-quality domestic corporate bond fund
while at the same time presenting less risk than a fund that invests
principally in securities rated below investment grade.  Certain of the debt
securities in which the Strategic Income Fund may invest may have, or be
considered comparable to securities having, the lowest ratings for
non-subordinated debt instruments assigned by Moody's or S&P (i.e., rated C by
Moody's or CCC or lower by S&P).  See "RISK FACTORS -- High Yield Securities --
General."

     In light of the risks associated with high yield corporate and sovereign
debt securities, SBAM will take various factors into consideration in
evaluating the creditworthiness of an issuer.  For corporate debt securities,
these will typically include the issuer's financial resources, its sensitivity
to economic conditions and trends, the operating history of the issuer, and the
experience and track record of the issuer's management.  For sovereign debt
instruments, these will typically include the economic and political conditions
within the issuer's country, the issuer's overall and external debt levels and
debt service ratios, the issuer's access to capital markets and other sources
of funding, and the issuer's debt service payment history.  SBAM will also
review the ratings, if any, assigned to the security by any recognized rating
agencies, although SBAM's judgment as to the quality of a debt security may
differ from that suggested by the rating published by a rating service.  The
Strategic Income Fund's ability to achieve its investment objective may be more
dependent on SBAM's credit analysis than would be the case if it invested in
higher quality debt securities.  A description of the ratings used by Moody's
and S&P is set forth in Appendix I to this Prospectus.

     The high yield sovereign debt securities in which the Strategic Income
Fund may invest are U.S. dollar-denominated and non-dollar-denominated debt
securities, including Brady Bonds, that are issued or guaranteed by governments
or governmental entities of developing and emerging countries.  SBAM expects
that these countries will consist primarily of those which have issued or have
announced plans to issue Brady Bonds, but the Portfolio is not limited to
investing in the debt of such countries.  Brady Bonds are debt securities
issued under the framework of the Brady Plan, an initiative announced by former
U.S. Treasury Secretary Nicholas F. Brady in 1989 as a mechanism for debtor
nations to restructure their outstanding external indebtedness.  SBAM
anticipates that the Portfolio's initial investments in sovereign debt will be
concentrated in Latin American countries, including Mexico and Central and
South American and Caribbean countries.  SBAM expects to take advantage of
additional opportunities for investment in the debt of North African countries,
such as Nigeria and Morocco, Eastern European countries, such as Poland and
Hungary, and Southeast Asian countries, such as the Philippines.  Sovereign
governments may include national, provincial, state, municipal or other foreign
governments with taxing authority.  Governmental entities may include the
agencies and instrumentalities of such governments, as well as state-owned
enterprises.  For a more detailed discussion on high yield sovereign debt
securities, see "OTHER INSTRUMENTS -- 5.  High Yield Foreign Sovereign Debt
Securities" in the Statement of Additional Information.

     The Strategic Income Fund will be subject to special risks as a result of
its ability to invest up to 100% of its assets in foreign securities.  These
risks are described under the captions "RISK FACTORS -- High Yield Securities"
and "RISK FACTORS -- Foreign Securities" in this Prospectus.  Moreover,
substantial investments in foreign securities may have adverse tax implications
as described under "GENERAL INFORMATION -- Taxes" in this Prospectus.  The
ability to spread its investments among the fixed-income markets in a number of
different countries may, however, reduce the overall level of market risk to
the extent it may reduce the Strategic Income Fund's exposure to a single
market.

     USE OF HEDGING AND OTHER STRATEGIC TRANSACTIONS.  The Strategic Income
Fund is currently authorized to use all of the various investment strategies
referred to under "RISK FACTORS -- Hedging and Other Strategic Transactions."
With the exception of currency transactions, however, it is not presently
anticipated that any of these strategies will be used to a significant degree
by the Portfolio.  The Statement of Additional Information contains a
description of these strategies and of certain risks associated therewith.

INVESTMENT QUALITY BOND FUND

     The investment objective of the Investment Quality Bond Fund is to provide
a high level of current income consistent with the maintenance of principal and
liquidity.

     Wellington Management manages the Investment Quality Bond Fund and seeks
to achieve its objective by investing primarily in a diversified portfolio of
investment grade corporate bonds and U.S. Government bonds with intermediate to
longer term maturities.  Investment management will emphasize sector analysis,
which focuses on relative value and yield spreads among security types and
among quality, issuer, and industry sectors, call protection and credit
research.  Credit research on corporate bonds is based on both quantitative and
qualitative criteria established by Wellington Management, such as an issuer's
industry, operating and financial profiles, business strategy, management
quality, and projected financial and business conditions.  Wellington
Management will attempt to maintain a high, steady and possibly growing income
stream.

     At least 65% of the Investment Quality Bond Fund's assets will be invested
in the following bonds:

     * marketable debt securities of domestic issuers and of foreign
     issuers (payable in U.S. dollars) rated at the time of purchase "A"
     or better by Moody's or S&P or, if unrated, of comparable quality as
     determined by Wellington Management; and

     * securities issued or guaranteed as to principal or interest by the U.S.
     Government or its agencies or instrumentalities, including mortgage-backed
     securities (described below under U.S. Government Securities Fund).

     The balance of the Investment Quality Bond Fund's investments may include:
domestic and foreign debt securities rated below "A" by Moody's and S&P (and
unrated securities of comparable quality as determined by Wellington
Management), preferred stocks, convertible securities (including those issued
in the Euromarket) and securities carrying warrants to purchase equity
securities, privately placed debt securities, asset-backed securities and
privately issued mortgage securities.  The Portfolio may also invest in cash or
cash equivalent securities which are authorized for purchase by the Money
Market Fund.  At least 65% of the Investment Quality Bond Fund's assets will be
invested in bonds and debentures.

     In pursuing its investment objective, the Investment Quality Bond Fund may
invest up to 20% of its assets in domestic and foreign high yield corporate and
government debt securities, commonly known as "junk bonds" (i.e., rated "B" or
below by Moody's (Moody's lowest rating is "C", See Appendix I) or "BB" or
below by S&P (S&P's lowest rating is "D", See Appendix I), or if unrated, of
comparable quality as determined by Wellington Management).  No minimum rating
standard is required for a purchase by the Portfolio.  The high yield sovereign
debt securities in which the Portfolio will invest are described above under
"Strategic Income Fund."  Domestic and foreign high yield debt securities
involve comparatively greater risks, including price volatility and risk of
default in the payment of interest and principal, than higher-quality
securities.  See "RISK FACTORS -- High Yield Securities."

     The Investment Quality Bond Fund may also invest in debt securities
carrying the fourth highest quality rating ("Baa" by Moody's or "BBB" by S&P)
and unrated securities of comparable quality as determined by Wellington
Management.  While such securities are considered investment grade and are
viewed to have adequate capacity for payment of principal and interest,
investments in such securities involve a higher degree of risk than that
associated with investments in debt securities in the higher rating categories
and such bonds lack outstanding investment characteristics and in fact have
speculative characteristics as well.  For example, 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 bonds.  While the Investment Quality Bond Fund may only invest up to 20%
of its assets in bonds rated below "Baa" by Moody's or "BBB" by S&P (or, if
unrated, of comparable quality as determined by Wellington Management) at the
time of investment, it is not required to dispose of downgraded bonds that
cause the Investment Quality Bond Fund to exceed this 20% maximum.

     The Investment Quality Bond Fund will be subject to certain risks as a
result of its ability to invest up to 20% of its assets in foreign securities.
These risks are described under the caption "RISK FACTORS -- Foreign
Securities" in this Prospectus.  Moreover, substantial investments in foreign
securities may have adverse tax implications as described under "GENERAL
INFORMATION -- Taxes" in this Prospectus.  The Investment Quality Bond Fund may
also invest in forward commitments and warrants.  See "RISK FACTORS --
Warrants" and "-- When-Issued Securities ("Forward Commitments")."

     USE OF HEDGING AND OTHER STRATEGIC TRANSACTIONS.  The Investment Quality
Bond Fund is currently authorized to use all of the various investment
strategies referred to under "RISK FACTORS -- Hedging and Other Strategic
Transactions."  The Statement of Additional Information contains a description
of these strategies and of certain risks associated therewith.

U.S. GOVERNMENT SECURITIES FUND

     The investment objective of the U.S. Government Securities Fund is to
obtain a high level of current income consistent with preservation of capital
and maintenance of liquidity.  SBAM manages the U.S. Government Securities Fund
and seeks to attain its objective by investing under normal circumstances 100%
of its assets in debt obligations and mortgage-backed securities issued or
guaranteed by the U.S. Government, its agencies or instrumentalities.  The
securities in which the U.S. Government Securities Fund may invest are:

     (1) mortgage-backed securities guaranteed by the Government National
Mortgage Association ("GNMA"), popularly known as "Ginnie Maes," that are
supported by the full faith and credit of the U.S. Government and which are the
"modified pass-through" type of mortgage-backed security ("GNMA Certificates").
Such securities entitle the holder to receive all interest and principal
payments due whether or not payments are actually made on the underlying
mortgages;

     (2) U.S. Treasury obligations;

     (3) obligations issued or guaranteed by agencies or instrumentalities of
the U.S. Government which are backed by their own credit and may not be backed
by the full faith and credit of the U.S. Government;

     (4) mortgage-backed securities guaranteed by agencies or instrumentalities
of the U.S. Government which are supported by their own credit but not the full
faith and credit of the U.S. Government, such as the Federal Home Loan Mortgage
Corporation and the Federal National Mortgage Association; and

     (5) collateralized mortgage obligations issued by private issuers for
which the underlying mortgage-backed securities serving as collateral are
backed (i) by the credit alone of the U.S. Government agency or instrumentality
which issues or guarantees the mortgage-backed securities, or (ii) by the full
faith and credit of the U.S. Government.

     The mortgage-backed securities in which the U.S. Government Securities
Fund invests (principally GNMA Certificates) represent participating interests
in pools of residential mortgage loans which are guaranteed by agencies or
instrumentalities of the U.S. Government.  However, the guarantee of these
types of securities runs only to the principal and interest payments and not to
the market value of such securities.  In addition, the guarantee only runs to
the portfolio securities held by the U.S. Government Securities Fund and not to
the purchase of shares of the Portfolio.

     Mortgage-backed securities are issued by lenders such as mortgage bankers,
commercial banks, and savings and loan associations.  Such securities differ
from conventional debt securities which provide for periodic payment of
interest in fixed amounts (usually semiannually) with principal payments at
maturity or specified call dates.  Mortgage-backed securities provide monthly
payments which are, in effect, a "pass-through" of the monthly interest and
principal payments (including any prepayments) made by the individual borrowers
on the pooled mortgage loans.  Principal prepayments result from the sale of
the underlying property or the refinancing or foreclosure of underlying
mortgages.

     The yield of mortgage-backed securities is based on the average life of
the underlying pool of mortgage loans, which is computed on the basis of the
maturities of the underlying instruments.  The actual life of any particular
pool may be shortened by unscheduled or early payments of principal and
interest.  The occurrence of prepayments is affected by a wide range of
economic, demographic and social factors and, accordingly, it is not possible
to accurately predict the average life of a particular pool.  For pools of
fixed rate 30-year mortgages, it has been common practice to assume that
prepayments will result in a 12-year average life.  The actual prepayment
experience of a pool of mortgage loans may cause the yield realized by the U.S.
Government Securities Fund to differ from the yield calculated on the basis of
the average life of the pool.  In addition, if any of these mortgage-backed
securities are purchased at a premium, the premium may be lost in the event of
early prepayment which may result in a loss to the Portfolio.

     Prepayments tend to increase during periods of falling interest rates,
while during periods of rising interest rates prepayments will most likely
decline.  Reinvestment by the U.S. Government Securities Fund of scheduled
principal payments and unscheduled prepayments may occur at higher or lower
rates than the original investment, thus affecting the yield of the Portfolio.
Monthly interest payments received by the Portfolio have a compounding effect
which will increase the yield to shareholders as compared to debt obligations
that pay interest semiannually.  Because of the reinvestment of prepayments of
principal at current rates, mortgage-backed securities may be less effective
than Treasury bonds of similar maturity at maintaining yields during periods of
declining interest rates.  Also, although the value of debt securities may
increase as interest rates decline, the value of these pass-through type of
securities may not increase as much due to the prepayment feature.

     While the Portfolio seeks a high level of current income, it cannot invest
in instruments such as lower grade corporate obligations which offer higher
yields but are subject to greater risks. The Portfolio will not knowingly
invest in a high risk mortgage security. The term "high risk mortgage security"
is defined generally as any mortgage security that exhibits greater price
volatility than a benchmark security,

                                       31

the Federal National Mortgage Association current coupon 30-year
mortgage-backed pass through security. Shares of the Portfolio are neither
insured nor guaranteed by the U.S. Government, its agencies or
instrumentalities.

     In order to make the U.S. Government Securities Fund an eligible
investment for federal credit unions ("FCUs"), federal savings and loan
institutions and national banks, the Portfolio will invest in U.S. Government
securities that are eligible for investment by such institutions without
limitation, and will also generally be managed so as to qualify as an eligible
investment for such institutions.  The Portfolio will comply with all
investment limitations applicable to FCUs including (i) the requirement that a
FCU may only purchase collateralized mortgage obligations which would meet the
high risk securities test of Part 703 of the National Credit Union
Administration Rules and Regulations or would be held solely to reduce interest
rate risk and (ii) the requirement that a FCU may not purchase zero coupon
securities having maturities greater than ten years.

     USE OF HEDGING AND OTHER STRATEGIC TRANSACTIONS.  The  U.S. Government
Securities Fund is not currently authorized to use any of the various
investment strategies referred to under "RISK FACTORS -- Hedging and Other
Strategic Transactions."  However, such strategies may be used in the future by
the Portfolio.  The Statement of Additional Information contains a description
of these strategies and of certain risks associated therewith.

NATIONAL MUNICIPAL BOND FUND

     The National Municipal Bond Fund's investment objective is to achieve a
high level of current income which is exempt from regular federal income taxes,
consistent with the preservation of capital, by investing primarily in a
portfolio of municipal obligations.  SBAM manages the National Municipal Bond
Fund and as a matter of fundamental policy, the Portfolio will invest under
normal circumstances, at least 80% of its net assets in municipal obligations
the interest on which is exempt from regular federal income tax.  A portion of
the Portfolio's dividends paid in respect of its shares may be subject to the
federal alternative minimum tax.  For a discussion on taxation of the National
Municipal Bond Fund, see "GENERAL INFORMATION -- National Municipal Bond Fund
- -- Taxation."

     The Portfolio will not invest in municipal obligations that are rated
below investment grade at the time of investment.  However, the Portfolio may
retain in its portfolio a municipal obligation whose rating drops below "Baa"
or "BBB" after its acquisition by the Portfolio, if SBAM considers the
retention of such obligation advisable.  The Portfolio intends to emphasize
investments in municipal obligations with long-term maturities and expects to
maintain an average portfolio maturity of 20 to 30 years and an average
portfolio duration of 8 to 11 years.  The average portfolio maturity and
duration, however, may be shortened from time to time depending on market
conditions.

     The types of obligations in which the National Municipal Bond Fund may
invest include the following:

     MUNICIPAL BONDS

     The Portfolio may invest in municipal bonds that are rated at the time of
purchase within the four highest ratings assigned by Moody's, S&P or Fitch, or
determined by SBAM to be of comparable quality.  The four highest ratings
currently assigned by Moody's to municipal bonds are "Aaa", "Aa", "A" and
"Baa"; the four highest ratings assigned by S&P and Fitch to municipal bonds
are "AAA", "AA", "A" and "BBB".  A more complete description of the debt
security ratings used by the Portfolio assigned by Moody's, S&P and Fitch is
included in Appendix I to this Prospectus.

     Although municipal obligations rated in the fourth highest rating category
by Moody's (i.e., "Baa") or S&P or Fitch (i.e., "BBB") are considered
investment grade, they may be subject to greater risks than other higher rated
investment grade securities.  Municipal obligations rated "Baa" by Moody's, for
example, are considered medium grade obligations that lack outstanding
investment characteristics and have speculative characteristics as well.
Municipal obligations rated "BBB" by S&P and Fitch are regarded as having an
adequate capacity to pay principal and interest.

     Municipal bonds are debt obligations that are typically issued to obtain
funds for various public purposes, such as construction of public facilities
(e.g., airports, highways, bridges and schools).  Municipal bonds at the time
of issuance are generally long-term securities with maturities of as much as
twenty years or more, but may have remaining maturities of shorter duration at
the time of purchase by the Portfolio.

     MUNICIPAL NOTES

     The Fund may invest in municipal notes rated at the time of purchase
"MIG1", "MIG2" (or "VMIG-1" or "VMIG-2", in the case of variable rate demand
notes), "P-2" or better by Moody's, "SP-2", "A-2" or better by S&P, or "F-2" or
better by Fitch, or if not rated, determined by SBAM to be of comparable
quality.


                                       32

<PAGE>   39

     Municipal notes are issued to meet the short-term funding requirements of
local, regional and state governments.  Municipal notes generally have
maturities at the time of issuance of three years or less.  Municipal notes
that may be purchased by the Portfolio include, but are not limited to:

     TAX ANTICIPATION NOTES.  Tax anticipation notes ("TANs") are sold as
interim financing in anticipation of collection of taxes.  An uncertainty in a
municipal issuer's capacity to raise taxes as a result of such factors as a
decline in its tax base or a rise in delinquencies could adversely affect the
issuer's ability to meet its obligations on outstanding TANs.

     BOND ANTICIPATION NOTES.  Bond anticipation notes ("BANs") are sold as
interim financing in anticipation of a bond sale.  The ability of a municipal
issuer to meet its obligations on its BANs is primarily dependent on the
issuer's adequate access to the longer term municipal bond market and the
likelihood that the proceeds of such bond sales will be used to pay the
principal of, and interest on, BANs.

     REVENUE ANTICIPATION NOTES.  Revenue anticipation notes ("RANs") are sold
as interim financing in anticipation of receipt of other revenues.  A decline
in the receipt of certain revenues, such as anticipated revenues from another
level of government, could adversely affect an issuer's ability to meet its
obligations on outstanding RANs.

     TANs, BANs and RANs are usually general obligations of the issuer.

     MUNICIPAL COMMERCIAL PAPER

     The Portfolio may also purchase municipal commercial paper that is rated
at the time of purchase "P-2" or better by Moody's, "A-2" or better by S&P, or
"F-2" or better by Fitch, or if not rated, determined by SBAM to be of
comparable quality.

     Municipal commercial paper that may be purchased by the Portfolio consists
of short term obligations of a municipality.  Such paper is likely to be issued
to meet seasonal working capital needs of a municipality or as interim
construction financing.  Municipal commercial paper, in many cases, is backed
by a letter of credit lending agreement, note repurchase agreement or other
credit facility agreement offered by banks or other institutions.

     CHARACTERISTICS OF MUNICIPAL OBLIGATIONS

     Municipal obligations are debt obligations issued by or on behalf of
states, cities, municipalities and other public authorities.  The two principal
classifications of municipal obligations that may be held by the Portfolio are
"general obligation" securities and "revenue" securities.  General obligation
securities are secured by the issuer's pledge of its full faith, credit and
taxing power for the payment of principal and interest.  Revenue securities are
payable only from the revenues derived from a particular facility or class of
facilities or, in some cases, from the proceeds of a special excise tax or
other specific revenue source such as the user of a facility being financed.
Revenue securities may include private activity bonds.  Such bonds may be
issued by or on behalf of public authorities to finance various privately
operated facilities and are not payable from the unrestricted revenues of the
issuer.  As a result, the credit quality of private activity bonds is
frequently related directly to the credit standing of private corporations or
other entities.  In addition, the interest on private activity bonds issued
after August 7, 1986 is subject to the federal alternative minimum tax.  The
Portfolio will not be restricted with respect to the proportion of its assets
that may be invested in such obligations.  Accordingly, the Portfolio may not
be a suitable investment vehicle for individuals or corporations that are
subject to the federal alternative minimum tax.

     The National Municipal Bond Fund's portfolio may also include "moral
obligation" securities, which are normally issued by special purpose public
authorities.  If the issuer of moral obligation securities is unable to meet
its debt service obligations from current revenues, it may draw on a reserve
fund, the restoration of which is a moral commitment but not a legal obligation
of the state or municipality that created the issuer.

     In addition, the Portfolio may invest in municipal lease obligations
("MLOs").  MLOs are not fully backed by the municipality's credit and their
interest may become taxable if the lease is assigned.  If the governmental user
does not appropriate sufficient funds for the following year's lease payments,
the lease will terminate, with the possibility of default on the MLO and loss
to the Portfolio.  SBAM intends to invest more than 5% of the Portfolio's net
assets in municipal lease obligations and the Trustees of the Fund have
established procedures the Subadviser will use to examine certain factors in
evaluating the liquidity of such obligations.  These factors include (i) the
frequency of trades and quotes for the MLO; (ii) the number of dealers willing
to purchase or sell such MLO and the number of other potential purchasers;
(iii) the willingness of dealers to undertake to make a market in the MLO; (iv)
the nature of the MLO and the nature of the marketplace trades (e.g., the time
needed to dispose of the security and the method of soliciting offers); (v) the
nature of the offering of such MLO (e.g., the size of the issue and the number
of anticipated holders); (vi) the ability of the MLO to maintain its
marketability throughout the time the instrument is held in the Portfolio; and
(vii) other factors, if any, which SBAM deems relevant to determining the
existence of a trading market for such MLO.  The Portfolio also may invest in
resource recovery bonds, which may be general obligations of the issuing
municipality or supported by corporate or bank guarantees.  The viability of
the resource recovery project, environmental protection regulations and project
operator tax incentives may affect the value and credit quality of resource
recovery bonds.

                                       33

     OTHER PERMITTED INVESTMENTS

     The Portfolio currently intends to invest substantially all of its assets
in obligations the interest on which is exempt from regular federal income
taxes.  However, in order to maintain liquidity, the Portfolio may invest up to
20% of its assets in taxable obligations, including taxable high-quality
short-term money market instruments.  The Portfolio may invest in the following
taxable high-quality short-term money market instruments:  obligations of the
U.S. Government or its agencies or instrumentalities; commercial paper of
issuers rated, at the time of purchase, "A-2" or better by S&P, "P-2" or better
by Moody's, or "F-2" or better by Fitch or which if unrated, in the opinion of
SBAM, are of comparable quality; certificates of deposit, bankers' acceptances
or time deposits of U.S. banks with total assets of at least $1 billion
(including obligations of foreign branches of such banks) and of the 75 largest
foreign commercial banks in terms of total assets (including domestic branches
of such banks), and repurchase agreements with respect to such obligations.

     If at some future date, in the opinion of SBAM, adverse conditions prevail
in the market for obligations the interest on which is exempt from regular
federal income taxes, the Portfolio may invest its assets without limit in
taxable high-quality short-term money market instruments.  Dividends paid by
the Portfolio that are attributable to interest derived from taxable money
market instruments will be taxable to investors.

     From time to time, the Portfolio may invest more than 25% of its assets in
obligations whose interest payments are from revenues of similar projects (such
as utilities or hospitals) or whose issuers share the same geographic location.
As a result, the Portfolio may be more susceptible to a single economic,
political or regulatory development than would a portfolio of securities with a
greater variety of issuers.  These developments include proposed legislation or
pending court decisions affecting the financing of such projects and market
factors affecting the demand for their services or products.

     Opinions relating to the validity of municipal obligations and to the
exemption of interest thereon from regular federal income tax are rendered by
bond counsel to the respective issuers at the time of issuance.  Neither the
Portfolio nor SBAM will review the proceedings relating to the issuance of
municipal obligations or the basis for such opinions.

     ADDITIONAL INVESTMENT ACTIVITIES

     FLOATING AND VARIABLE RATE OBLIGATIONS.  Certain of the obligations that
the National Municipal Bond Fund may purchase may have a floating or variable
rate of interest.  Floating or variable rate obligations bear interest at rates
that are not fixed, but vary with changes in specified market rates or indices,
such as the prime rate, and at specified intervals.  Certain of the floating or
variable rate obligations that may be purchased by the Portfolio may carry a
demand feature that would permit the holder to tender them back to the issuer
of the underlying instrument or to a third party at par value prior to
maturity.  Such obligations include variable rate demand notes, which are
instruments issued pursuant to an agreement between the issuer and the holder
that permit the indebtedness thereunder to vary and provide for periodic
adjustments in the interest rate.

     PARTICIPATION CERTIFICATES.  The instruments that may be purchased by the
Portfolio include participation certificates issued by a bank, insurance
company or other financial institution in obligations owned by such
institutions or affiliated organizations that may otherwise be purchased by the
Portfolio.  A participation certificate gives the Portfolio an undivided
interest in the underlying obligations in the proportion that the Portfolio's
interest bears to the total principal amount of such obligations.  Certain of
such participation certificates may carry a demand feature that would permit
the holder to tender them back to the issuer or to a third party prior to
maturity.
                                     
     VARIABLE RATE AUCTION SECURITIES AND INVERSE FLOATERS.  The National
Municipal Bond Fund may invest in variable rate auction securities and inverse
floaters which are instruments created when an issuer or dealer separates the
principal portion of a long-term, fixed-rate municipal bond into two long-term,
variable-rate instruments.  The interest rate on the variable rate auction
portion reflects short-term interest rates, while the interest rate on the
inverse floater portion is typically higher than the rate available on the
original fixed-rate bond.  Changes in the interest rate paid on the portion of
the issue relative to short-term interest rates inversely affect the  interest
rate paid on the latter portion of the issue.  The latter portion therefore is
subject to greater price volatility than the original fixed-rate bond.  Since
the market for these instruments is new, the holder of one portion may have
difficulty finding a ready purchaser.  Depending on market availability, the
two portions may be recombined to form a fixed-rate municipal bond.


     USE OF HEDGING AND OTHER STRATEGIC TRANSACTIONS

     The National Municipal Bond Fund is currently authorized to use only
certain of the various investment strategies referred to under "RISK FACTORS --
Hedging and Other Strategic Transactions."  Specifically, the Portfolio may
purchase or sell futures contracts on (a) debt securities that are backed by
the full faith and credit of the U.S. Government, such as long-term U.S.
Treasury Bonds and Treasury Notes and (b) municipal bond indices.  Currently,
at least one exchange trades futures contracts on an index of long-term
municipal bonds, and the Portfolio reserves the right to conduct futures
transactions based on an index which may be developed in the future to
correlate with

                                       34

<PAGE>   41

price movements in municipal obligations.  It is not presently anticipated that
any of these strategies will be used to a significant degree by the Portfolio.
The Statement of Additional Information contains a description of these
strategies and of certain risks associated therewith.

MONEY MARKET FUND

     The investment objective of the Money Market Fund is to obtain maximum
current income consistent with preservation of principal and liquidity as is
available from short-term investments.   Wellington Management manages the
Money Market Fund and seeks to achieve this objective by investing in high
quality, U.S. dollar-denominated money market instruments of the following
types:

     (1)  obligations issued or guaranteed as to principal or interest by the
U.S. Government, or any agency or authority controlled or supervised by and
acting as an instrumentality of the U.S. Government pursuant to authority
granted by Congress (hereinafter "U.S. Government securities");

     (2)  certificates of deposit and bankers' acceptances of U.S. banks,
foreign branches of U.S. banks, foreign banks and U.S. savings and loan
associations which at the date of investment have capital, surplus and
undivided profits as of the date of their most recent published financial
statements in excess of $100,000,000 (or less than $100,000,000 if the
principal amount of such bank obligations is insured by the Federal Deposit
Insurance Corporation or the Savings Association Insurance Fund);

     (3)  commercial paper which at the date of investment is rated (or
guaranteed by a company whose commercial paper is rated) within the two highest
rating categories by any nationally recognized statistical rating organization
("NRSRO") (such as "P-1" or "P-2" by Moody's or "A-1" or "A-2" by S&P) or, if
not rated, is issued by a company which  Wellington Management, acting pursuant
to guidelines established by the Trustees, has determined to be of minimal
credit risk and comparable quality;

     (4)  corporate obligations maturing in thirteen months or less which at
the date of investment are rated within the two highest rating categories by
any NRSRO (such as "Aa" or higher by Moody's or "AA" or higher by S&P); and

     (5)  repurchase agreements with respect to any of the foregoing
obligations (without limitation).

     Commercial paper may include variable amount master demand notes, which
are obligations that permit investment of fluctuating amounts at varying rates
of interest.  Such notes are direct lending arrangements between the Money
Market Fund and the note issuer, and Wellington Management will monitor the
creditworthiness of the issuer and its earning power and cash flow, and will
also consider situations in which all holders of such notes would redeem at the
same time.  Variable amount master demand notes are redeemable on demand.

     The Money Market Fund will invest only in U.S. dollar-denominated
instruments.  All of the Money Market Fund's investments will mature in
thirteen months or less and the Portfolio will maintain a dollar-weighted
average portfolio maturity of 90 days or less.  By limiting the maturity of its
investments, the Money Market Fund seeks to lessen the changes in the value of
its assets caused by fluctuations in short-term interest rates.  Due to the
short maturities of its investments, the Money Market Fund will tend to have a
lower yield than, and the value of its underlying investments will be less
volatile than the investments of, portfolios that invest in longer-term
securities.  In addition, the Money Market Fund will invest only in securities
the Trustees determine to present minimal credit risks and which at the time of
purchase are "eligible securities" as defined by Rule 2a-7 under the 1940 Act.
Generally, eligible securities must be rated by a NRSRO in one of the two
highest rating categories for short-term debt obligations or be of comparable
quality.  The Money Market Fund also intends to maintain a stable per share net
asset value of $1.00, although there is no assurance that it will be able to do
so.

     USE OF HEDGING AND OTHER STRATEGIC TRANSACTIONS.  The Money Market Fund is
not authorized to use any of the various investment strategies referred to
under "RISK FACTORS --Hedging and Other Strategic Transactions."

                        ------------------------------

     The portfolio turnover rate of each of the Fund's Portfolios may vary from
year to year, as well as within a year.  Higher portfolio turnover rates can
result in corresponding increases in portfolio transaction costs for a
Portfolio.  See "PORTFOLIO TURNOVER" in the Statement of Additional
Information.

     The ability of the U.S. Government Securities Fund to provide a high level
of current income and the ability of the Money Market Fund to obtain maximum
current income is restrained because that Portfolio invests predominantly in
U.S. Government bonds; debt obligations and mortgage-backed securities issued
or guaranteed by the U.S. Government, its agencies or instrumentalities; and
U.S. dollar-denominated money market instruments, respectively.

                                  RISK FACTORS

INVESTMENT RESTRICTIONS GENERALLY

     The Fund is subject to a number of restrictions in pursuing its investment
objectives and policies.  Such restrictions generally serve to limit investment
practices that may subject the Fund to investment and market risk.  The
following is a brief summary of certain restrictions that may be of interest to
investors.  Some of these restrictions are subject to exceptions not stated
here.  Such exceptions and a complete list of the investment restrictions
applicable to the individual Portfolios and to the Fund are set forth in the
Statement of Additional Information under the caption "INVESTMENT
RESTRICTIONS."

     Except for the restrictions specifically identified as fundamental, all
investment restrictions described in this Prospectus and in the Statement of
Additional Information are not fundamental, so that the Trustees of the Fund
may change them without shareholder approval.  Fundamental policies may not be
changed without the affirmative vote of a majority of the outstanding voting
securities.

     Fundamental policies applicable to all Portfolios include prohibitions on
(i) investing more than 25% of the total assets of any Portfolio in the
securities of issuers having their principal activities in any particular
industry (with exceptions for U.S. Government securities and, with respect to
the Money Market Fund, obligations of domestic branches of U.S. banks, and with
respect to the National Municipal Bond Fund, obligations issued or guaranteed
by any state or territory, and possession of the United States, the District of
Columbia, or any of their authorities, agencies, instrumentalities or political
subdivisions) (for purposes of this restriction, supranational issuers will be
considered to comprise an industry as will each foreign government that issues
securities purchased by a Portfolio); (ii) borrowing money (including entering
into reverse repurchase agreements), except for temporary or emergency purposes
and then not in excess of 10% of the value of the total assets of the Portfolio
at the time the borrowing is made (a Portfolio will not purchase additional
securities at any time its borrowings exceed 5% of total assets); and (iii)
purchasing securities of any issuer if the purchase would cause more than 5% of
the value of a Portfolio's total assets to be invested in the securities of any
one issuer (excluding U.S. Government securities and bank obligations) or cause
more than 10% of the voting securities of the issuer to be held by a Portfolio,
except that up to 25% of the value of each Portfolio's total assets (except the
Money Market Fund) may be invested without regard to this restriction.

     Restrictions that apply to all Portfolios and that are not fundamental
include prohibitions on (i) knowingly investing more than 10% of the net assets
of any Portfolio in "illiquid" securities (including repurchase agreements
maturing in more than seven days but excluding master demand notes), (ii)
pledging, hypothecating, mortgaging or transferring more than 10% of the total
assets of any Portfolio as security for indebtedness, and (iii) purchasing
securities of other investment companies, other than in connection with a
merger, consolidation or reorganization, if the purchase would cause more than
10% of the value of a Portfolio's total assets to be invested in investment
company securities.

     Finally, the Money Market Fund is subject to certain restrictions required
by Rule 2a-7 under the 1940 Act.  In order to comply with such restrictions,
the Money Market Fund will, among other things, not purchase the securities of
any issuer if it would cause (i) more than 5% of its total assets to be
invested in the securities of any one issuer (excluding U.S. Government
securities and repurchase agreements fully collateralized by U.S. Government
securities), except as permitted by Rule 2a-7 for certain securities for a
period of up to three business days after purchase, (ii) more than 5% of its
total assets to be invested in "second tier securities," as defined by Rule
2a-7, or (iii) more than the greater of $1 million or 1% of its total net
assets to be invested in the second tier securities of that issuer.
HIGH YIELD SECURITIES

     GENERAL.  The Strategic Income Fund may invest without limitation, and the
Investment Quality Bond Fund may invest up to 20% of its assets, in "high
yield" securities.  Securities rated below investment grade and comparable
unrated securities offer yields that fluctuate over time, but generally are
superior to the yields offered by higher rated securities.  However, securities
rated below investment grade also involve greater risks than higher rated
securities.  Under rating agency guidelines, medium- and lower-rated securities
and comparable unrated securities will likely have some quality and protective
characteristics that are outweighed by large uncertainties or major risk
exposures to adverse conditions.  Certain of the debt securities in which the
Strategic Income and Investment Quality Bond Funds may invest may have, or be
considered comparable to securities having, the lowest ratings for
non-subordinated debt instruments assigned by Moody's or S&P (i.e., rated C by
Moody's or CCC or lower by S&P).  These securities are considered to have
extremely poor prospects of ever attaining any real investment standing, to
have a current identifiable vulnerability to default, to be unlikely to have
the capacity to pay interest and repay principal when due in the event of
adverse business, financial or economic conditions, and/or to be in default or
not current in the payment of interest or principal.  Such securities are
considered speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligations.
Accordingly, it is possible that these types of factors could, in certain
instances, reduce the value of securities held by the Strategic Income and
Investment Quality Bond Funds with a commensurate effect on the
value of the Portfolio's shares.  The Strategic Income Fund may invest without
limitation in high yield debt securities, and accordingly, it should not be
considered as a complete investment program for all investors.

                                       36

<PAGE>   43

     Because the Strategic Income and Investment Quality Bond Funds will invest
primarily in fixed-income securities, the net asset value of each Portfolio's
shares can be expected to change as general levels of interest rates fluctuate,
although the market values of securities rated below investment grade and
comparable unrated securities tend to react less to fluctuations in interest
rate levels than do those of higher-rated securities.  Except to the extent
that values are affected independently by other factors such as developments
relating to a specific issuer, when interest rates decline, the value of a
fixed-income portfolio can generally be expected to rise.  Conversely, when
interest rates rise, the value of a fixed-income portfolio can generally be
expected to decline.

     The secondary markets for high yield corporate and sovereign debt
securities are not as liquid as the secondary markets for higher rated
securities.  The secondary markets for high yield debt securities are
concentrated in relatively few market makers and participants in the market are
mostly institutional investors, including insurance companies, banks, other
financial institutions and mutual funds.  In addition, the trading volume for
high yield debt securities is generally lower than that for higher-rated
securities and the secondary markets could contract under adverse market or
economic conditions independent of any specific adverse changes in the
condition of a particular issuer.  These factors may have an adverse effect on
the Strategic Income and Investment Quality Bond Funds' ability to dispose of
particular portfolio investments and may limit the ability of those Portfolios
to obtain accurate market quotations for purposes of valuing securities and
calculating net asset value.  If the Strategic Income or Investment Quality
Bond Fund is not able to obtain precise or accurate market quotations for a
particular security, it will become more difficult for the Board of Trustees to
value such Portfolio's investment portfolio and the Fund's Trustees may have to
use a greater degree of judgment in making such valuations.  Less liquid
secondary markets may also affect a Portfolio's ability to sell securities at
their fair value.  In addition, each Portfolio may invest up to 10% of its net
assets, measured at the time of investment, in illiquid securities, which may
be more difficult to value and to sell at fair value.  If the secondary markets
for high yield debt securities are affected by adverse economic conditions, the
proportion of a Portfolio's assets invested in illiquid securities may
increase.

     CORPORATE DEBT SECURITIES.  While the market values of securities rated
below investment grade and comparable unrated securities tend to react less to
fluctuations in interest rate levels than do those of higher-rated securities,
the market values of certain of these securities also tend to be more sensitive
to individual corporate developments and changes in economic conditions than
higher-rated securities.  In addition, such securities generally present a
higher degree of credit risk.  Issuers of these securities are often highly
leveraged and may not have more traditional methods of financing available to
them, so that their ability to service their debt obligations during an
economic downturn or during sustained periods of rising interest rates may be
impaired.  The risk of loss due to default by such issuers is significantly
greater than with investment grade securities because such securities generally
are unsecured and frequently are subordinated to the prior payment of senior
indebtedness.  The current economic recession has resulted in default levels in
excess of historic averages.

     FOREIGN SOVEREIGN DEBT SECURITIES.  Investing in foreign sovereign debt
securities will expose the Strategic Income and Investment Quality Bond Funds
to the direct or indirect consequences of political, social or economic changes
in the developing and emerging countries that issue the securities.  The
ability and willingness of sovereign obligors in developing and emerging
countries or the governmental authorities that control repayment of their
external debt to pay principal and interest on such debt when due may depend on
general economic and political conditions within the relevant country.
Countries such as those in which these Portfolios may invest have historically
experienced, and may continue to experience, high rates of inflation, high
interest rates, exchange rate trade difficulties and extreme poverty and
unemployment.  Many of these countries are also characterized by political
uncertainty or instability.  Additional factors which may influence the ability
or willingness to service debt include, but are not limited to, a country's
cash flow situation, the availability of sufficient foreign exchange on the
date a payment is due, the relative size of its debt service burden to the
economy as a whole, and its government's policy towards the International
Monetary Fund, the World Bank and other international agencies.

     The ability of a foreign sovereign obligor to make timely payments on its
external debt obligations will also be strongly influenced by the obligor's
balance of payments, including export performance, its access to international
credits and investments, fluctuations in interest rates and the extent of its
foreign reserves.  A country whose exports are concentrated in a few
commodities or whose economy depends on certain strategic imports could be
vulnerable to fluctuations in international prices of these commodities or
imports.  To the extent that a country receives payment for its exports in
currencies other than dollars, its ability to make debt payments denominated in
dollars could be adversely affected.  If a foreign sovereign obligor cannot
generate sufficient earnings from foreign trade to service its external debt,
it may need to depend on continuing loans and aid from foreign governments,
commercial banks and multilateral organizations, and inflows of foreign
investment.  The commitment on the part of these foreign governments,
multilateral organizations and others to make such disbursements may be
conditioned on the government's implementation of economic reforms and/or
economic performance and the timely service of its obligations.  Failure to
implement such reforms, achieve such levels of economic performance or repay
principal or interest when due may result in the cancellation of such third
parties' commitments to lend funds, which may further impair the obligor's
ability or willingness to timely service its debts.  The cost of servicing
external debt will also generally be adversely affected by rising international
interest rates, because many external debt obligations bear interest at rates
which are adjusted based upon international interest rates.  The ability to
service external debt will also depend on the level of the relevant
government's international currency reserves and its access to
foreign exchange.  Currency devaluations may affect the ability of a sovereign
obligor to obtain sufficient foreign exchange to service its external debt.

                                       37

<PAGE>   44
        As a result of the foregoing, a governmental obligor may default on its
obligations.  If such an event occurs, the Strategic Income or Investment
Quality Bond Fund may have limited legal recourse against the issuer and/or
guarantor.  Remedies must, in some cases, be pursued in the courts of the
defaulting party itself, and the ability of the holder of foreign sovereign
debt securities to obtain recourse may be subject to the political climate in
the relevant country.  In addition, no assurance can be given that the holders
of commercial bank debt will not contest payments to the holders of other
foreign sovereign debt obligations in the event of default under their
commercial bank loan agreements.

        Sovereign obligors in developing and emerging countries are among the
world's largest debtors to commercial banks, other governments, international
financial organizations and other financial institutions.  These obligors have
in the past experienced substantial difficulties in servicing their external
debt obligations, which led to defaults on certain obligations and the
restructuring of certain indebtedness.  Restructuring arrangements have
included, among other things, reducing and rescheduling interest and principal
payments by negotiating new or amended credit agreements or converting
outstanding principal and unpaid interest to Brady Bonds, and obtaining new
credit to finance interest payments.  Holders of certain foreign sovereign debt
securities may be requested to participate in the restructuring of such
obligations and to extend further loans to their issuers.  There can be no
assurance that the Brady Bonds and other foreign sovereign debt securities in
which the Portfolios may invest will not be subject to similar restructuring
arrangements or to requests for new credit which may adversely affect a
Portfolio's holdings.  Furthermore, certain participants in the secondary
market for such debt may be directly involved in negotiating the terms of these
arrangements and may therefore have access to information not available to
other market participants.

        In addition to high yield foreign sovereign debt securities, the
Strategic Income and Investment Quality Bond Funds may also invest in
investment grade foreign securities.  For a discussion of such securities and
their associated risks, see "Foreign Securities" below.

FOREIGN SECURITIES

        Each of the Growth, Growth and Income, Asset Allocation, Investment
Quality Bond and Money Market Funds may invest up to 20% of its total assets in
securities of foreign issuers.  Such foreign securities may be denominated in
foreign currencies, except with respect to the Money Market Fund which may only
invest in U.S. dollar-denominated securities of foreign issuers.  The Global
Growth, International Growth and Income and Strategic Income Funds may each,
without limitation, invest up to 100% of its assets in securities issued by
foreign entities and/or denominated in foreign currencies.  The U.S. Government
Securities and National Municipal Bond Fund may not invest in foreign
securities.

        Securities of foreign issuers include obligations of foreign branches
of U.S. banks and of foreign banks, common and preferred stocks, debt
securities issued by foreign governments, corporations and supranational
organizations, and American Depository Receipts, European Depository Receipts
and Global Depositories Receipts.   ("ADRs", "EDRs" and "GDRs", respectively). 
ADRs are U.S. dollar-denominated securities backed by foreign securities
deposited in a U.S. securities depository.  ADRs are created for trading in the
U.S. markets. The value of an ADR will fluctuate with the value of the
underlying security, reflect any changes in exchange rates and otherwise
involve risks associated with investing in foreign securities. ADRs in which
the Portfolios may invest may be sponsored or unsponsored. There may be less
information available about foreign issuers of unsponsored ADRs. EDRs and GDRs
are receipts evidencing an arrangement with a non-U.S. bank similar to that for
ADRs and are designed for use in non-U.S. securities markets.  EDRs and GDRs
are not necesarily quoted in the same currency as the underlying security. 
Each of the Portfolios, except for the Global Growth and Strategic Income
Funds, anticipates that its foreign investments will consist primarily of ADRs
that are regularly traded on recognized U.S. exchanges or in the U.S.
"over-the-counter" market.

        Foreign securities may be subject to foreign government taxes which
reduce their attractiveness.  See "GENERAL INFORMATION -- Taxes."  In addition,
investing in securities denominated in foreign currencies and in the securities
of foreign issuers, particularly non-governmental issuers, involves risks which
are not ordinarily associated with investing in domestic issuers.  These risks
include political or economic instability in the country involved and the
possibility of imposition of currency controls.  Since certain Portfolios may
invest in securities denominated or quoted in currencies other than the U.S.
dollar, changes in foreign currency exchange rates may affect the value of
investments in the Portfolio and the unrealized appreciation or depreciation of
investments insofar as U.S. investors are concerned.  Foreign currency exchange
rates are determined by forces of supply and demand on the foreign exchange
markets.  These forces are, in turn, affected by the international balance of
payments and other economic and financial conditions, government intervention,
speculation and other factors.  The Portfolios may incur transaction charges in
exchanging foreign currencies.

        There may be less publicly available information about a foreign issuer
than about a domestic issuer.  Foreign issuers, including foreign branches of
U.S. banks, are subject to different accounting and reporting requirements
which are generally less extensive than the requirements applicable to domestic
issuers.  Foreign stock markets (other than Japan) have substantially less
volume than the U.S. exchanges and securities of foreign issuers are generally
less liquid and more volatile than those of comparable domestic issuers.  These
risks are heightened in the case of emerging markets.  There is frequently less
governmental regulation of exchanges, broker-dealers and issuers than in the
United States, and brokerage costs may be higher.  In addition, investments in
foreign companies may be subject to the possibility of nationalization,
withholding of dividends at the source, expropriation or confiscatory taxation,
currency blockage, political or economic 

                                      38

<PAGE>   45
instability or diplomatic developments that could adversely affect the value of
those investments.  Finally, in the event of a default on any foreign
obligation, it may be difficult for the Fund to obtain or to enforce a judgment
against the issuer.

        Foreign markets, especially emerging markets, may have different
clearance and settlement procedures, and in certain markets there have been
times when settlements have been unable to keep pace with the volume of
securities transactions, making it difficult to conduct such transactions. 
Delays in settlement could result in temporary periods when a portion of the
assets of a Portfolio is uninvested and no return is earned thereon.  The
inability of a Portfolio to make intended security purchases due to settlement
could cause the Portfolio to miss attractive investment opportunities. 
Inability to dispose of portfolio securities due to settlement problems could
result in losses to a Portfolio due to subsequent declines in values of the
portfolio securities or, if the Portfolio has entered into a contract to sell
the security, possible liability to the purchaser.  Certain foreign markets,
especially emerging markets, may require governmental approval for the
repatriation of investment income, capital or the proceeds of sales of
securities by foreign investors.  A Portfolio could be adversely affected by
delays in, or a refusal to grant, any required governmental approval for
repatriation of capital, as well as by the application to the Portfolio of any
restrictions on investments.

        In addition to the foreign securities listed above, the Strategic
Income and Investment Quality Bond Funds may also invest in foreign sovereign
debt securities, which involve certain additional risks.  See "RISK FACTORS --
High Yield Securities -- Foreign Sovereign Debt Securities" above.

WARRANTS

        Subject to certain restrictions, each of the Portfolios except the
National Municipal Bond and Money Market Funds may purchase warrants, including
warrants traded independently of the underlying securities. It is a
non-fundamental investment restriction of each Portfolio not to purchase
warrants if as a result that Portfolio would then have more than 10% of its
total net assets invested in warrants, or if more than 5% of the value of the
Portfolio's total net assets would be invested in warrants which are not listed
on a recognized United States or foreign stock exchange, except for warrants
included in units or attached to other securities.

LENDING PORTFOLIO SECURITIES

        To attempt to increase its income, each Portfolio may lend its
portfolio securities in amounts up to 33% of its total non-cash assets to
brokers, dealers and other financial institutions, provided such loans are
callable at any time by the Portfolio and are at all times fully secured by
cash or equivalent collateral marked to market value of loaned securities on a
daily basis. As with any extensions of credit, there may be risks of delay in
recovery and in some cases even loss of rights in the collateral should the
borrower of the securities fail financially. However, these loans of portfolio
securities will only be made to firms deemed by the Subadvisers to be
creditworthy.

WHEN-ISSUED SECURITIES ("FORWARD COMMITMENTS")

        In order to help ensure the availability of suitable securities, each
of the Portfolios may purchase debt securities on a "when-issued" or on a
"forward delivery" basis, which means that the obligations will be delivered to
the Portfolio at a future date, which may be a month or more after the date of
commitment (referred to as "forward commitments").  It is expected that, under
normal circumstances, a Portfolio purchasing securities on a when-issued or
forward delivery basis will take delivery of the securities, but the Portfolio
may sell the securities before the settlement date, if such action is deemed
advisable.  In general, a Portfolio does not pay for the securities or start
earning interest on them until the purchase of the obligation is scheduled to
be settled, but it does, in the meantime, record the transaction and reflect
the value each day of the securities in determining its net asset value.  At
the time delivery is made, the value of when-issued or forward delivery
securities may be more or less than the transaction price, and the yields then
available in the market may be higher than those obtained in the transaction.
While awaiting delivery of the obligations purchased on such bases, a Portfolio
will establish a segregated account consisting of cash or liquid high quality
debt securities equal to the amount of the commitments to purchase when-issued
or forward delivery securities.  The availability of liquid assets for this
purpose and the effect of asset segregation on a Portfolio's ability to meet
its current obligations, to honor requests for redemption and to have its
investment portfolio managed properly will limit the extent to which the
Portfolio may purchase when-issued or forward delivery securities.  Except as
may be imposed by these factors, there is no limit on the percentage of a
Portfolio's total assets that may be committed to such transactions.

HEDGING AND OTHER STRATEGIC TRANSACTIONS

        Individual Portfolios may be authorized to use a variety of investment
strategies described below for hedging purposes only, including hedging various
market risks (such as interest rates, currency exchange rates and broad or
specific market movements), and managing the effective maturity or duration of
debt instruments held by the Portfolio.  The description in this Prospectus of
each Portfolio indicates which, if any, of these types of transactions may be
used by the Portfolio.  Although these strategies are regularly used by some
investment companies and other institutional investors, it is not presently
anticipated that any of these strategies will be used to a significant degree
by any Portfolio unless otherwise specifically indicated in the description of
the Portfolio contained in this Prospectus.  Limitations on 

                                      39

<PAGE>   46

the portion of a Portfolio's assets that may be used in connection with the     
investment strategies described below are set out in the Statement of Additional
Information.

        Subject to the constraints described above, an individual Portfolio may
(if and to the extent so authorized) purchase and sell (or write)
exchange-listed and over-the-counter put and call options on securities, index
futures contracts, financial futures contracts and fixed-income indices and
other financial instruments, enter into financial futures contracts, enter into
interest rate transactions, and enter into currency transactions (collectively,
these transactions are referred to in this Prospectus as "Hedging and Other
Strategic Transactions").  Other Strategic Transactions are also referred to as
derivative transactions.  A "derivative" is generally defined as an instrument
whose value is based upon, or derived from, some underlying index, reference
rate (e.g. interest rate or currency exchange rate, security, commodity or
other asset). Portfolio's interest rate transactions may take the form of
swaps, caps, floors and collars, and a Portfolio's currency transactions may
take the form of currency forward contracts, currency futures contracts,
currency swaps and options on currencies or currency futures contracts.

        Hedging and Other Strategic Transactions may generally be used to
attempt to protect against possible changes in the market value of securities
held or to be purchased by a Portfolio resulting from securities markets or
currency exchange rate fluctuations, to protect a Portfolio's unrealized gains
in the value of its securities, to facilitate the sale of those securities for
investment purposes, to manage the effective maturity or duration of a
Portfolio's securities or to establish a position in the derivatives markets as
a temporary substitute for purchasing or selling particular securities.  A
Portfolio may use any or all types of Hedging and Other Strategic Transactions
which it is authorized to use at any time; no particular strategy will dictate
the use of one type of transaction rather than another, as use of any
authorized Hedging and Other Strategic Transaction will be a function of
numerous variables, including market conditions.  The ability of a Portfolio to
utilize Hedging and Other Strategic Transactions successfully will depend on,
in addition to the factors described above, the Subadviser's ability to predict
pertinent market movements, which cannot be assured.  These skills are
different from those needed to select a Portfolio's securities.  None of the
Portfolios is a "commodity pool" (i.e., a pooled investment vehicle which
trades in commodity futures contracts and options thereon and the operator of
which is registered with the Commodity Futures Trading Commission (the
"CFTC")).  Futures contracts and options on futures contracts will be
purchased, sold or entered into only for BONA FIDE hedging to the extent
permitted by CFTC regulations.  The use of certain Hedging and Other Strategic
Transactions will require that a Portfolio segregate cash, liquid high grade
debt obligations or other assets to the extent a Portfolio's obligations are
not otherwise "covered" through ownership of the underlying security, financial
instrument or currency.  Risks associated with Hedging and Other Strategic
Transactions are described in "HEDGING AND OTHER STRATEGIC TRANSACTIONS -- Risk
Factors" in the Statement of Additional Information.  A detailed discussion of
various Hedging and Other Strategic Transactions, including applicable
regulations of the CFTC and the requirement to segregate assets with respect to
these transactions, also appears in the Statement of Additional Information.

ILLIQUID SECURITIES

        Each of the Portfolios is precluded from investing in excess of 10% of
its net assets in securities that are not readily marketable.  Excluded from
the 10% limitation are securities that are restricted as to resale but for
which a ready market is available pursuant to exemption provided by Rule 144A
adopted under the Securities Act of 1933, as amended (the "1933 Act") or other
exemptions from the registration requirements of the 1933 Act.  Whether
securities sold pursuant to Rule 144A are readily marketable for purposes of
the Fund's investment restriction is a determination to be made by the
Subadvisers, subject to the Trustees' oversight and for which the Trustees are
ultimately responsible.  The Subadvisers will also monitor the liquidity of
Rule 144A securities held by the Portfolios for which they are responsible.  To
the extent Rule 144A securities held by a Portfolio should become illiquid
because of a lack of interest on the part of qualified institutional investors,
the overall liquidity of the Portfolio could be adversely affected.  In
addition, the Money Market Fund may invest in commercial paper issued in
reliance on the exemption from registration afforded by Section 4(2) of the
1933 Act.  Section 4(2) commercial paper is restricted as to the disposition
under federal securities law, and is generally sold to institutional investors,
such as the Fund, who agree that they are purchasing the paper for investment
purposes and not with a view to public distribution.  Any resale by the
purchaser must be made in an exempt transaction.  Section 4(2) commercial paper
is normally resold to other institutional investors like the Money Market Fund
through or with the assistance of the issuer or investment dealers who make a
market in Section 4(2) commercial paper, thus providing liquidity.  The Money
Market Fund's subadviser believes that Section 4(2) commercial paper meets its
criteria for liquidity and is quite liquid.  The Money Market Fund intends,
therefore, to treat Section 4(2) commercial paper as liquid and not subject to
the investment limitation applicable to illiquid securities.  The Money Market
Fund's subadviser will monitor the liquidity of Section 4(2) commercial paper
held by the Money Market Fund, subject to the Trustees' oversight and for which
the Trustees are ultimately responsible.

        Each of the Fund's Portfolios may enter into repurchase agreements and
the International Growth and Income and U.S. Government Securities Funds may
enter into reverse repurchase agreements. Repurchase agreements involve the
acquisition by a Portfolio of debt securities subject to an agreement to resell
them at an agreed-upon price. Under a repurchase agreement, at the time the
Portfolio acquires a security, it agrees to resell it to the original seller (a
financial institution or broker/dealer which meets the guidelines established
by the Trustees) and must deliver the security (and/or securities that may be
added to or substituted for it under the repurchase agreement) to the original
seller on an agreed-upon date in the future. The repurchase price is in excess
of the purchase price.  The arrangement is in economic effect a loan
collateralized by securities.

                                      40

<PAGE>   47
        The Trustees have adopted procedures that establish certain
creditworthiness, asset and collateralization requirements for the
counterparties to a Portfolio's repurchase agreements.  The Trustees will
regularly monitor the use of repurchase agreements and the Subadvisers will,
pursuant to procedures adopted by the Trustees, continuously monitor the amount
of collateral held with respect to a repurchase transaction so that it equals
or exceeds the amount of the obligation.

        A Portfolio's risk in a repurchase transaction is limited to the
ability of the seller to pay the agreed-upon sum on the delivery date. In the
event of bankruptcy or other default by the seller, there may be possible
delays and expenses in liquidating the instrument purchased, decline in its
value and loss of interest.  Securities subject to repurchase agreements will
be valued every business day and additional collateral will be requested if
necessary so that the value of the collateral is at least equal to the value of
the repurchase obligation, including the interest accrued thereon.

        Only the International Growth and Income and U.S. Government Securities
Funds may enter into "reverse" repurchase agreements.  Under a reverse
repurchase agreement, each of the International Growth and Income and U.S.
Government Securities Funds may sell a debt security and agree to repurchase it
at an agreed upon time and at an agreed upon price. Each such Portfolio retains
record ownership of the security and the right to receive interest and
principal payments thereon.  At an agreed upon future date, such Portfolio
repurchases the security by remitting the proceeds previously received, plus
interest.  The difference between the amount the Portfolio receives for the
security and the amount it pays on repurchase is deemed to be payment of
interest.  Each such Portfolio will maintain in a segregated custodial account
cash, Treasury bills or other U.S. Government securities having an aggregate
value equal to the amount of such commitment to repurchase including accrued
interest, until payment is made. In certain types of agreements, there is no
agreed-upon repurchase date and interest payments are calculated daily, often
based on the prevailing overnight repurchase rate.  The Securities and Exchange
Commission (the "Commission") views these transactions as collateralized
borrowings by a Portfolio and as a result, each such Portfolio will abide by
the guidelines and limitations set out in fundamental restriction number 3 in
the Statement of Additional Information with respect to the borrowing of money.


                            MANAGEMENT OF THE FUND

        Under Massachusetts law and the Fund's Declaration of Trust and
By-Laws, the business and affairs of the Fund are managed under the direction
of the Trustees.

ADVISORY ARRANGEMENTS

        NASL Financial Services, Inc., ("NASL Financial" or, in its capacity as
investment adviser to the Fund, the "Adviser"), a Massachusetts corporation
whose principal offices are located at  116 Huntington Avenue, Boston,
Massachusetts 02116, is the investment adviser to the Fund.  NASL Financial is
a wholly-owned subsidiary of North American Security Life Insurance Company
("Security Life"), a Delaware stock life insurance company which is part of The
North American Group, a diversified group of financial service companies based
in Toronto, Canada currently with over $16 billion in assets under management.

        Pursuant to its Advisory Agreement with the Fund (the "Advisory
Agreement"), the Adviser oversees the administration of all aspects of the
business and affairs of the Fund; selects, contracts with and compensates
subadvisers to manage the assets of the Fund's Portfolios; and reimburses the
Fund if the total of certain expenses allocated to any Portfolio exceeds
certain limitations. The Adviser serves as investment adviser to one other
investment company, NASL Series Trust.  NASL Series Trust is a mutual fund that
serves as the underlying investment medium for variable annuity contracts
issued by Security Life and its wholly-owned subsidiary, First North American
Life Assurance Company.  At July 31, 1995, NASL Series Trust had assets of
approximately $4.6 billion.

        Under the terms of the Advisory Agreement, the Adviser selects,
contracts with and compensates subadvisers to manage the investment and
reinvestment of the assets of the Portfolios of the Fund.  The Adviser monitors
the compliance of such subadvisers with the investment objectives and related
policies of each Portfolio and reviews the performance of such subadvisers and
reports periodically on such performance to the Trustees.

        The Adviser oversees all aspects of the Fund's business and affairs. 
In that connection, the Adviser permits its directors, officers and employees
to serve as Trustees or President, Vice President, Treasurer or Secretary of
the Fund, without cost to the Fund.  The Adviser also provides certain
services, and the personnel to perform such services, to the Fund for which the
Fund reimburses the Adviser's costs of providing such services and personnel. 
Such services include maintaining certain records of the Fund and performing
all administrative, financial, accounting, bookkeeping and recordkeeping
functions of the Fund, except for any of those functions performed by the
Fund's custodian or transfer and shareholder servicing agents.  The
reimbursement paid by the Fund to the Adviser for personnel costs include
employee compensation and allocated portions of the Adviser's related personnel
expenses of office space, utilities, office equipment and miscellaneous office
expenses.


                                      41

<PAGE>   48
        The Adviser has agreed to reduce a Portfolio's advisory fee, or if
necessary to reimburse the Fund, in order to prevent the expenses of a
Portfolio from exceeding either the most restrictive expense limitation imposed
by applicable state law or a fixed expense limitation contained in the Advisory
Agreement, whichever results in the lowest expenses to the Fund.  The fixed
limitation may be terminated by the Adviser on October 31, 1995 or October 31
of subsequent years on 30 days' written notice.  The most restrictive state law
provision limits a Portfolio's annual expenses, excluding taxes, portfolio
brokerage commissions, interest, certain litigation and indemnification
expenses, extraordinary expenses and a portion of the Portfolio's distribution
fees, to 2.5% of the first $30,000,000 of the average net assets of the
Portfolio, 2.0% of the next $70,000,000 and 1.5% of the remaining average net
assets of the Portfolio. The fixed limitation contained in the Advisory
Agreement, and as of the date of this Prospectus the operative limitation on
the Fund's expenses, limits a Portfolio's annual expenses, excluding taxes,
portfolio brokerage commissions, interest, certain litigation and
indemnification expenses, extraordinary expenses and all of the Portfolio's
distribution fees as a percentage of average net assets to 1.40% for the Global
Growth and the International Growth and Income Funds, .99% for the Growth,
Growth and Income and Asset Allocation Funds, 1.15% for the Strategic Income
Fund, .90% for the Investment Quality Bond and U.S. Government Securities
Funds, 0.84% for the National Municipal Bond Fund and .50% for the Money Market
Fund.

<TABLE>
        As compensation for its services, the Adviser receives a fee from the
Fund computed separately for each Portfolio.  The fee for each Portfolio is
stated as an annual percentage of the current value of the net assets of the
Portfolio.  The fee, which is accrued daily and payable monthly, is calculated
for each day by multiplying the fraction of one over the number of calendar
days in the year by the annual percentage prescribed for a Portfolio, and
multiplying this product by the value of the net assets of the Portfolio at the
close of business on the previous business day of the Fund.  The following is a
schedule of the management fees each Portfolio currently is obligated to pay
the Adviser under the Advisory Agreement (prior to the application of any fee
waivers):

As of March 16, 1993, August 1, 1994 and November 23, 1992, respectively, the
Growth, Growth and Income and Asset Allocation Funds reached sufficient size to
realize a reduction in the fee as a percent of excess net assets.  The fees
paid by the Global Growth, International Growth and Income and Strategic Income
Funds are higher than the fees paid by many funds to their advisers, but are
not higher than the fees paid by many funds with similar investment objectives
and policies.

        Under the terms of each of the subadvisory agreements between the
Adviser and a Subadviser (the "Subadvisory Agreements"), the Subadviser
assigned to a Portfolio manages the investment and reinvestment of the assets
of such Portfolio, subject to the supervision of the Trustees.  The Subadviser
formulates a continuous investment program for such Portfolio consistent with
its investment objectives and policies outlined in this Prospectus. The
Subadviser implements such programs by purchases and sales of securities and
regularly reports to the Adviser and the Trustees with respect to their
implementation.  The factors considered by the Subadvisers in allocating
brokerage among broker/dealers are described in the Statement of Additional
Information under the caption "PORTFOLIO BROKERAGE."  Among the factors that
may be considered is the willingness of broker/dealers to sell shares of the
Fund.

        As compensation for their services, the Subadvisers receive fees from
the Adviser computed separately for each Portfolio. The fee for each Portfolio
is stated as an annual percentage of the current value of the net assets of the
Portfolio.  The fee, which is accrued daily and payable monthly, is calculated
for each day by multiplying the fraction of one over the number of calendar
days in the year by the annual percentage prescribed for a Portfolio, and
multiplying this product by the value of the net assets of the Portfolio at the
close of business on the previous business day of the Fund. Once the average
net assets of a Portfolio exceed specified amounts, the fee is reduced with
respect to the excess. Absent any applicable fee waivers, the following is a
schedule of the management fees the Adviser is obligated to pay the Subadvisers
for each Portfolio under the Subadvisory Agreements.  THESE FEES ARE PAID OUT
OF THE ADVISORY FEES DESCRIBED ABOVE AND ARE NOT ADDITIONAL CHARGES TO THE
PORTFOLIOS OR THEIR SHAREHOLDERS.

                             GENERAL INFORMATION

NET ASSET VALUE

        The net asset value of the shares of each class of each Portfolio is
calculated separately and, except as described below, is determined once daily
as of the close of regularly scheduled trading on the New York Stock Exchange
(the "Exchange"), Monday through Friday.  Net asset value per share of each
class of each Portfolio (other than the Money Market Fund, as described below)
is calculated by dividing the value of the portion of the Portfolio's
securities and other assets attributable to that class, less the liabilities
attributable to that class, by the number of shares of that class outstanding.
No determination is required on (i) days on which changes in the value of such
Portfolio's securities holdings will not materially affect the current net
asset value of the shares of the Portfolio, (ii) days during which no shares of
such Portfolio are tendered for redemption and no order to purchase or sell
such shares is received by the Fund, or (iii) the following business holidays
or the days on which such holidays are observed by the Exchange:  New Year's
Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day and Christmas Day.  Generally, trading in non-U.S. securities,
as well as U.S. Government securities and money market instruments, is
substantially completed each day at various times prior to the close of
regularly scheduled trading on the Exchange.  The values of such securities
used in computing the net asset value of the shares of a class of a Portfolio
are generally determined as of such times.  Occasionally, events which affect
the values of such securities may occur between the times at which they are
generally determined and the close of regularly scheduled trading on the
Exchange and would therefore not be reflected in the computation of a class's
net asset value.  If events materially affecting the value of such securities
occur during such period, then these securities will be valued at their fair
value as determined in good faith by the Subadvisers under procedures
established and regularly reviewed by the Trustees.

        Securities held by each of the Portfolios other than the Money Market
Fund, except for money market instruments with remaining maturities of 60 days
or less, are valued as follows: securities which are traded on stock exchanges
are valued at the last sales price as of the close of the Exchange, or lacking
any sales, at the closing bid prices. Securities traded only in the
"over-the-counter" market are valued at the last bid prices quoted by brokers
that make markets in the securities at the close of trading on the Exchange.
Securities and assets for which market quotations are not readily available or
not obtained from a pricing service are valued at fair value as determined in
good faith by the Trustees, although the actual calculations may be made by
persons acting pursuant to the direction of the Trustees.  If approved by the
Trustees, the Fund may make use of a pricing service or services in determining
the net asset value of the classes of the Portfolios.

        The Trustees have authorized the Portfolios to value certain debt
securities by reference to valuations obtained from pricing services which take
into account appropriate factors such as institution-size trading in similar
groups of securities, yield, quality, coupon rate, maturity, type of issue,
trading characteristics and other market data in determining valuations of such
securities, without extensive reliance upon quoted prices, since such
valuations are believed by the Trustees to more accurately reflect the fair
value of such securities.

        All instruments held by the Money Market Fund and money market
instruments with a remaining maturity of 60 days or less held by the other
Portfolios are valued on an amortized cost basis.  With respect to each class
of shares of the Money Market Fund, this method of calculation facilitates
maintaining a constant net asset value of $1.00 per share.  However, there can
be no assurance that the $1.00 net asset value will be maintained at all times. 
The Trustees have determined that the amortized cost method of valuation fairly
reflects a market based net asset value.

DIVIDENDS AND DISTRIBUTIONS

        Except for the National Municipal Bond Fund, each Portfolio's dividends
from net investment income together with distributions of short-term capital
gains (collectively "income dividends") are taxable as ordinary income to
shareholders whether paid in additional shares or in cash.  Any long-term
capital gains ("capital gains distributions") distributed to shareholders are
treated as such by the shareholders, whether paid in cash or additional shares,
regardless of the length of time a shareholder has owned his or her shares.
Shareholders are provided annually with full information on dividends and
capital gains distributions for tax purposes. Shareholders may not have to pay
state or local taxes on dividends derived from interest on U.S. Government
obligations.  Shareholders should consult their tax advisers regarding the
applicability of state and local taxes to dividends and distributions.  Each
Portfolio will send shareholders a statement after the end of every calendar
year stating the amount of dividends derived from interest on U.S. Government
obligations.

        The Global Growth, Growth, and Asset Allocation Funds declare and pay
any income dividends annually; the Growth and Income and International Growth
and Income Funds declare and pay any income dividends semiannually; and the
Strategic Income, Investment Quality Bond, U.S. Government Securities, National
Municipal Bond, and Money Market Funds declare income dividends daily and pay
them monthly.  See "PURCHASE OF SHARES -- General Methods of Purchasing
Shares."  Each of the Portfolios, other than the Money Market Fund, declares
and pays any capital gains dividends annually.  Generally, income dividends of
Portfolios other than the Strategic Income, Investment Quality Bond, U.S.
Government Securities, National Municipal Bond and Money Market Funds and
capital gains dividends of Portfolios other than the Money Market Fund paid
shortly after a purchase of shares prior to the record date, although in effect
a return of capital, will be subject to income tax.

        The maximum distribution and service fees payable by the Class B shares
and Class C shares of each Portfolio (other than the Money Market Fund, which
bears no such fees) are more than the maximum fees payable by each such
Portfolio's Class A shares.  In addition, certain incremental expenses which
are specifically allocable to a particular class of shares in a Portfolio are
separately allocated to that class of shares.  As a result, the per share
dividend on Class B and Class C shares will generally be lower than the per
share dividend on Class A shares of a Portfolio.

        For the convenience of shareholders, all income dividends and capital
gains distributions are paid in full and fractional shares of the same class of
a Portfolio on the payment date unless a shareholder has requested payment in
cash.  Shareholders may elect to have dividends and distributions from a class
of a Portfolio invested in shares of the same class of another Portfolio at the
respective net asset value.  See SHAREHOLDER SERVICES -- Automatic Dividend
Diversification."

TAXES

        It is expected that each Portfolio of the Fund will qualify as a
"regulated investment company" under the Internal Revenue Code of 1986, as
amended (the "Code").  To so qualify, each Portfolio intends to distribute to
shareholders as dividends or capital gains distributions substantially all of
its net investment income and net realized capital gains, if any.  The
requirements for qualification as a regulated investment company may cause a
Portfolio to restrict the degree to which it engages in short-term trading and
transactions in options and futures contracts.  Qualification as a regulated
investment company relieves the Fund and each Portfolio of any liability for
federal income taxes to the extent its earnings are distributed in accordance
with applicable provisions of the Code.  Each Portfolio will be subject to a 4%
nondeductible excise tax on its taxable income to the extent it does not meet
certain distribution requirements by the end of each calendar year.  Each
Portfolio intends to make sufficient distributions to avoid application of this
excise tax.

        Funds investing in foreign securities or currencies may be required to
pay withholding or other taxes to foreign governments. Foreign tax withholding
from dividends and interest, if any, is generally from 10% to 35%, although
lesser and greater amounts may be incurred. The investment yield of the
Portfolios investing in foreign securities or currencies will be reduced by
these foreign taxes. Shareholders will bear the cost of any foreign taxes, but
may not be able to claim a foreign tax credit or deduction for these foreign
taxes. If a Portfolio is eligible for and makes an election to allow the
shareholders of that Portfolio to claim a foreign tax credit or deduction for
these taxes for any taxable year, the shareholders will be notified. In
addition, Portfolios investing in securities of passive foreign investment
companies may be subject to U.S. federal income taxes (and interest on such
taxes) as a result of such investments. The investment yield of the Portfolios
making such investments will be reduced by these taxes and interest.
Shareholders will bear the cost of these taxes and interest, but will not be
able to claim a deduction for these amounts.

        The redemption, sale or exchange of Fund shares (including the exchange
of shares of one Portfolio for shares of another) is a taxable event and may
result in a gain or loss.  Gain or loss, if any, recognized on the sale or
other disposition of shares of the Fund will be taxed as capital gain or loss
if the shares are capital assets in the shareholder's hands.  Generally, a
shareholder's gain or loss will be a long-term gain or loss if the shares have
been held for more than one year.  If a shareholder sells or otherwise disposes
of a share of the Fund before holding it for more than six months, any loss on
the sale or other disposition of such share shall be treated as a long-term
capital loss to the extent of any capital gain dividends received by the
shareholder with respect to such share.  A loss realized on a sale or exchange
of shares may be disallowed if other shares are acquired within a 61-day period
beginning 30 days before and ending 30 days after the date that the shares are
disposed of.

        Unless a shareholder of any Portfolio includes his or her taxpayer
identification number (social security number for individuals) in the
Shareholder Application and certifies that he or she is not subject to backup
withholding, the Fund is required to withhold and remit to the U.S. Treasury
31% of non-exempt distributions and other reportable payments to the
shareholder.

NATIONAL MUNICIPAL BOND FUND - TAXATION

        The National Municipal Bond Fund intends to qualify and elect to be
treated as a regulated investment company under the Code.  The National
Municipal Bond Fund will be subject to federal corporate income tax currently
at a 35% rate on any undistributed income other than tax-exempt income from
municipal obligations and to alternative minimum tax currently at a 20% rate on
alternative minimum taxable income, which includes interest income on certain
"private activity" obligations that is otherwise exempt from tax.  The National
Municipal Bond Fund also intends to satisfy conditions under the Code that will
enable interest from municipal obligations, which is exempt from regular
federal income taxes in the hands of each Portfolio, to qualify as
"exempt-interest dividends" when distributed to such Portfolio's shareholders.
Under the Code, such dividends are exempt from regular federal income taxes.

        Although exempt-interest dividends paid by the National Municipal Bond
Fund will be excluded by shareholders of the Portfolios from their gross income
for regular federal income tax purposes, under the Code all or a portion of
such dividends may be (i) a preference item for purposes of the alternative
minimum tax, (ii) a component of the "ACE" adjustment for purposes of
determining the amount of corporate alternative minimum tax or (iii) a factor
in determining the extent to which a shareholder's Social Security benefits are
taxable.  Moreover, the receipt of exempt-interest dividends from each of the
Portfolios may increase a corporate shareholder's liability for

                                      48

<PAGE>   55
environmental taxes under Section 59A of the Code and may also affect the
federal tax liability of certain foreign corporations, S Corporations and
insurance companies.  Furthermore, under the Code, interest on indebtedness
incurred or continued to purchase or carry portfolio shares, which interest is
deemed to relate to exempt-interest dividends, will not be deductible by
shareholders of the Portfolio for federal income tax purposes.

        The National Municipal Bond Fund intends that substantially all
dividends and distributions it pays to its shareholders will be designated as
exempt-interest dividends and as such will be exempt from regular federal
income taxes.  However, to the extent each Portfolio earns income from taxable
investments or realizes capital gains, some portion of its dividends and
distributions may not qualify as exempt-interest dividends and may be subject
to regular federal income taxes.

        The exemption of exempt-interest dividend income from regular federal
income taxation does not necessarily result in similar exemptions for such
income under the income or other tax laws of state or local taxing authorities.
In general, states exempt from state income tax only that portion of any
exempt-interest dividend that is derived from interest received by a regulated
investment company on its holdings of obligations issued by that state or its
political subdivisions and instrumentalities.

        A notice detailing the tax status of dividends and distributions paid
by the National Municipal Bond Fund will be mailed annually to the National
Municipal Bond Fund's shareholders.  As part of this notice, the Portfolio will
report to its shareholders the percentage of interest income earned by the
Portfolio during the preceding year on tax-exempt obligations indicating, on a
state-by-state basis, the source of such income.

                             --------------------

        Descriptions of tax consequences set forth in this Prospectus and in
the Statement of Additional Information are intended to be a general guide.
Investors should consult their tax advisers concerning a prospective investment
in the Fund.

PERFORMANCE INFORMATION

        From time to time the Fund may advertise certain information about the
performance of all classes of one or more of the Portfolios.  Such performance
information may include time periods prior to the establishment of the
multi-class distribution system, as described more fully in the Statement of
Information under the caption "PERFORMANCE INFORMATION."  Information about
performance of a class of shares of a Portfolio is not intended to indicate
future performance.  The Fund's annual report to shareholders, which is
available without charge upon request, contains further discussions of Fund
performance.

        The Fund may advertise the yield and/or total return performance for
all classes of one or more of the Portfolios in accordance with the rules of
the Commission.  The National Municipal Bond Fund may also present from time to
time yield, tax-equivalent yield and standardized and nonstandardized total
return in advertisements.  When yield is used in sales literature, the total
return figures will also be included.  The Commission has issued rules setting
forth the uniform calculation of both yield and total return, but shareholders'
actual experience may be more or less than the figures produced by these
formulas.

        Each Portfolio may include the total return for all classes of shares
in advertisements or other written material.  Each such piece will include at
least the average annual total return quotations for one year, five years, ten
years (if available) and/or from the commencement of operations.  Total return
is measured by comparing the value of an investment at the beginning of the
relevant period to the redemption value of the investment at the end of the
period; the calculation assumes the initial investment is made at the current
maximum net offering price, assumes immediate reinvestment of any dividends or
capital gains distributions and adjusts for the current maximum sales charge of
4.75% for Class A shares and the applicable CDSC imposed on a redemption of
Class B shares or Class C shares held for the period indicated.  Yield and
total return are calculated separately for each class of a Portfolio.

        Each of the Portfolios may advertise yield for all classes, accompanied
by total return.  The yield will be computed by dividing the net investment
income per share earned during a recent one month period (after deducting
expenses net of reimbursements applicable to each class) by the maximum
offering price (including the maximum front end sales charge or applicable
CDSC) on the last day of the period, and annualizing the result (assuming
compounding of interest) in order to arrive at annual percentage rate.  The
National Municipal Bond Fund may also present from time to time the
tax-equivalent yield of all classes.  The tax-equivalent yield is calculated by
determining the portion of yield which is tax-exempt and calculating the
equivalent taxable yield and adding to such amount any fully taxable yield.

        The Money Market Fund may advertise yield and effective yield for all
classes.  The yield is based upon the income earned by the Portfolio over a
seven-day period and is then annualized, i.e., the income earned in the period
is assumed to be earned every seven days over a 365 day period and is stated as
a percentage of the investment.  Effective yield is calculated similarly, but
when annualized the income earned by the investment is assumed to be reinvested
weekly in shares of the same class and thus compounded in the course of a 365
day period.  The effective yield will be higher than the yield because of the
compounding effect of this assumed reinvestment.


                                      49

<PAGE>   56
        All performance information may be compared with data published by
Lipper Analytical Services, Inc. or to unmanaged indices of performance,
including, but not limited to, the Dow Jones Industrial Average, Standard &
Poor's 500, Value Line Composite, Lehman Brothers Bond, Government Corporate,
Corporate and Aggregate Indices, Merrill Lynch Government & Agency and
Intermediate Agency Indices, the EAFE Index or the Morgan Stanley Capital
International World Index.  In addition, during certain time periods the yield
and total return of a class and/or a Portfolio may be affected by expense
waivers and/or expense reimbursements. When so affected, the yield and total
return figures will be accompanied by a statement regarding such waiver and/or
reimbursement.  While performance information may be helpful in evaluating
whether a Portfolio may be fulfilling its objective, past performance should
not be regarded as representative of future results.  Yields and net asset
values will fluctuate with market conditions and the value of shares redeemed
may be more or less than their cost.  The Money Market Fund operates under
procedures designed to stabilize the net asset value of all classes at $1.00
per share.  The Fund will include performance data for each class of a
Portfolio in any advertisement or information including performance data of
such Portfolio.  The Fund may also utilize performance information in
hypothetical illustrations provided in narrative form.

ORGANIZATION OF THE FUND

        The Fund was organized as a Massachusetts business trust on September
28, 1988.  The Growth, U.S. Government Securities and Money Market Funds
commenced operations on August 28, 1989 with the acquisition of substantially
all the assets of the corresponding portfolios of Hidden Strength Funds.  The
Global Growth Fund became available to investors on November 7, 1990, and the
Growth and Income and Investment Quality Bond Funds became available to
investors on May 1, 1991.  The Asset Allocation Fund became available July 13,
1992, following the combination of the former Conservative, Moderate and
Aggressive Asset Allocation Trusts into the Asset Allocation Fund.  The former
asset allocation trusts commenced operations August 28, 1989 with the
acquisition of substantially all the assets of the corresponding portfolios of
Hidden Strength Funds.  The National Municipal Bond Fund became available to
investors on June 30, 1993.  The Strategic Income Fund became available to
investors on November 30, 1993.  The International Growth and Income Fund
became available to investors on June 9, 1995.

        All shares of beneficial interest, $.001 par value per share, of each
Portfolio have equal voting rights (except as described below with respect to
matters specifically affecting a class of shares) and have no pre-emptive or
conversion rights.  At a meeting of the Board of Trustees held on December 16,
1993, the Trustees, including each Trustee who is not an "interested person,"
as such term is defined under the 1940 Act, unanimously approved amendments to
the Fund's Declaration of Trust to permit implementation of the Multiple
Pricing System.  Shareholders of the Fund approved these amendments at a
special meeting held on February 18, 1994.  The Multiple Pricing System was
implemented on April 1, 1994.  An order dated February 28, 1994 was issued to
the Fund and NASL Financial by the Commission permitting the issuance and sale
of multiple classes of shares representing interests in the Fund's existing
Portfolios.  Shares of each class of a Portfolio represent interests in that
Portfolio in proportion to each share's net asset value.  The per share net
asset value of each class of shares in a Portfolio is calculated separately and
may differ as between classes as a result of the differences in distribution
and service fees payable by the classes and the allocation of certain
incremental class-specific expenses to the appropriate class to which such
expenses apply.

        All shares of the Fund have equal voting rights and will be voted in
the aggregate, and not by series (Portfolio) or class, except where voting by
series or class is required by law or where the matter involved affects only
one series or class (for example, matters pertaining to the plan of
distribution relating to Class A shares will only be voted on by Class A
shares).  Matters required by the 1940 Act to be voted upon by each affected
series include changes to (i) the Advisory Agreement, (ii) a Subadvisory
Agreement and (iii) fundamental investment objectives and policies.  The Fund
is not generally required to hold annual meetings of shareholders. However, the
Trustees may call special meetings of shareholders for action by shareholder
vote as may be requested in writing by the holders of 25% or more of the
outstanding shares of the Fund (10% in the case of a meeting requested for the
purpose of removing a Trustee) or as may be required by applicable laws.
Shareholders seeking to call a meeting for the purpose of removing a Trustee
will be assisted by the Fund in communicating with other shareholders, provided
the shareholders seeking to call a meeting are at least ten in number, have
been shareholders for at least six months and hold in the aggregate at least
one percent of the outstanding shares or shares having a value of at least
$25,000, whichever is less.  Also, Trustees may be removed by action of the
holders of two-thirds or more of the outstanding shares of the Fund.  The
Trustees are authorized to create additional series and classes of shares at
any time without approval by shareholders.

        Under Massachusetts law, shareholders of a business trust may, in
certain circumstances, be held personally liable as partners for the
obligations of the Fund.  However, the Declaration of Trust pursuant to which
the Fund was organized contains an express disclaimer of shareholder liability
for acts or obligations of each Portfolio of the Fund and requires that notice
of such disclaimer be given in each instrument entered into or executed by the
Fund. The Declaration of Trust also provides for indemnification out of a
Portfolio's property for any shareholder of such Portfolio held personally
liable for any of the Portfolio's obligations.  Thus, the risk of a shareholder
being personally liable as a partner for obligations of a Portfolio is limited
to the unlikely circumstance in which the Portfolio itself would be unable to
meet its obligations.

                              PURCHASE OF SHARES

INTRODUCTION

        The Fund offers three classes of shares in each Portfolio to the
general public.  Purchases of Class A shares of less than $1 million are sold
with a front end sales charge.  Purchases of Class A shares of $1 million or
more made on or after May 1, 1995 are offered for sale at net asset value
without a front end sales charge but may be subject to a CDSC upon redemption. 
Class B shares are sold without a front end sales charge but may be subject to
a CDSC upon redemption.  Class C shares are sold without a front end sales
charge, but may be subject to a CDSC upon redemption.  Shares of all classes of
the Money Market Fund are sold at net asset value (without the imposition of a
front end sales charge or CDSC).  See "MULTIPLE PRICING SYSTEM" for a
discussion of factors to consider in selecting which class of shares to
purchase.

        Shares are offered continuously for sale through securities dealers and
banks which have executed an agreement (a "Dealer Agreement") with NASL
Financial, the distributor of the Fund's shares (in such capacity, the
"Distributor").

        The initial purchase of any class of shares in any Portfolio must be at
least $1,000, with the exception that the initial purchase to a retirement plan
account may be made with a minimum of $50.  In addition, an account can be
established with a minimum of $50 if the account will be receiving periodic,
regular investments through programs such as Automatic Investment Plans,
Automatic Dividend Diversification, and Systematic Investing (see "SHAREHOLDER
SERVICES -- Additional Shareholder Privileges" for a description of these
programs).  The minimum for subsequent investments is $50.

        When purchasing shares of any Portfolio of the Fund, investors must
specify whether the purchase is for Class A, Class B or Class C shares.

GENERAL METHODS OF PURCHASING SHARES

        1.   BY MAIL.  To make an initial account purchase, mail a check made
payable to "North American Funds" with a completed New Account Application

                                      51

<PAGE>   58
        2.   BY FEDERAL FUNDS WIRE.  Shares may be purchased in any Portfolio
by wire transfer.  To obtain instructions for Federal Funds Wire purchases,
please contact the Customer Service Department at (800) 872-8037.

        3.   THROUGH A SECURITIES DEALER.  You may purchase shares by
contacting a securities dealer who has a Dealer Agreement with the Distributor.

        Orders for shares of all Portfolios except the Money Market Fund will
be assigned the next closing price after receipt of the order.  Orders for the
Money Market Fund will be assigned the next closing price after the payment has
been converted to Federal Funds and dividends will begin to accrue on the
business day after such conversion.  While orders for shares of the Strategic
Income, Investment Quality Bond, U.S. Government Securities and National
Municipal Bond Fund are assigned the next closing price after receipt of the
order, dividends will begin to accrue on the business day after the purchase
has been converted into Federal Funds.

SHARE PRICE

        The public offering price of the Class A shares of each Portfolio is
the net asset value per share (next determined following receipt of an order)
plus, in the case of all Portfolios except the Money Market Fund, a front end
sales charge, if applicable.  The share price for Class B shares and Class C
shares is the net asset value per share (next determined following receipt of
an order).

CLASS A SHARES

        The public offering price for purchases of Class A shares of less than
$1 million is the net asset value per share plus a front end sales charge,
expressed as a percentage of the offering price as set forth in the table
below.  No front end sales charge is imposed on the purchase of Class A shares
of the Money Market Fund.  However, when Class A shares of the Money Market
Fund on which no sales charge has been paid or waived are exchanged for Class A
shares of another Portfolio, the sales charge applicable to purchases of Class
A shares will be assessed at that time.  Purchases of Class A shares of $1
million or more are offered for sale at net asset value subject to a CDSC of 1%
of the dollar amount subject thereto if redeemed within one year of purchase.
See "PURCHASES OF SHARES --Contingent Deferred Sales Charge" below.  The CDSC
may be waived on certain redemptions of shares.  See "PURCHASES OF SHARES -
Waiver of CDSC."

**  For purchases of Class A shares of $1 million or more the Distributor will
pay a commission to dealers as follows:  1.00% on sales up to $5 million (0.50%
for sales of the National Municipal Bond Fund), plus 0.50% of the amount in
excess of $5 million; provided, however, that the Distributor may pay a
commission on sales in excess of $5 million of up to 1.00% to certain dealers
which, at the Distributor's invitation, enter into an agreement with the
Distributor in which the dealer agrees to return any commission paid to it on
the sale (or a pro rata portion thereof) if the shareholder redeems his shares
within a period of time after purchase as specified by the Distributor.
Purchases of $1 million or more for each shareholder account will be aggregated
over a 12 month period (commencing from the date of the first such purchase)
for purposes of determining the level of commission to be paid during that
period with respect to such account.

                                      52

<PAGE>   59
        The Distributor may reallow concessions to securities dealers with whom
it has agreements and retain the balance over such concessions, and at times
the Distributor may reallow the entire front end sales charge to such dealers. 
In such circumstances, dealers may be deemed to be underwriters under the 1933
Act.  Also, during an initial offering period following the introduction of a
new portfolio, and from time to time thereafter, additional amounts may be paid
by the Distributor or its promotional agent that would result in total dealer
concessions exceeding the offering price.

        The Distributor may also pay banks and other financial service firms
("Service Organizations") that provide services for their clients to facilitate
transactions in Class A shares of a Portfolio, a transaction fee up to an
amount equal to the greater of the full applicable front end sales charge or
the "Concession to a Broker Dealer as a Percentage of Offering Price" as shown
in the above table. Banks are currently prohibited under the Glass-Steagall Act
from providing certain underwriting or distribution services.  If banking firms
are prohibited from acting in any capacity or providing any of the described
services, management will consider what action, if any, is appropriate.  It is
not anticipated that termination of a relationship with a bank would result in
any material adverse consequences to a Portfolio.  In addition, State
securities laws may differ from federal laws regarding Service Organizations
which may be required to register under State securities laws as brokers and/or
dealers.

REDUCED SALES CHARGES

        Investors purchasing Class A shares may be able to benefit from a
reduction or elimination of the front end sales charge through several purchase
plans.

        RIGHT OF ACCUMULATION.  For the purposes of determining which sales
charge level in the table above is applicable to a purchase of Class A shares,
investors may combine the total of the value of the shares being purchased with
the amount equal to the current net asset value of the investor's holdings of
shares in all Portfolios of the Fund, including holdings in Class B and Class C
shares, but excluding shares purchased or held in the Money Market Fund.  Also,
for purposes of the foregoing calculation, shares (including holdings in Class
B and Class C shares, but excluding shares purchased or held in the Money
Market Fund) beneficially owned by the investor's spouse and the investor's
children under the age of 21 may, upon written notice to the transfer agent,
also be included in the investor's beneficial holdings at the current net asset
value to reach a level specified in the above table.  The investor must notify
the transfer agent in writing of all share accounts to be considered in
exercising the right of accumulation described above.

        STATEMENT OF INTENTION.  For the purposes of determining which sales
charge level in the table above is applicable to a purchase of Class A shares,
investors may also establish a total investment goal in shares of the Fund to
be achieved over a thirteen-month period and may purchase Class A shares during
such period at the applicable reduced front end sales charge.  All shares,
including Class B shares and Class C shares (but excluding shares purchased or
held in the Money Market Fund), previously purchased and still beneficially
owned by the investor and his or her spouse and children under the age of 21
may, upon written notice to the transfer agent, also be included at the current
net asset value to reach a level specified in the table above.

        Shares totaling 5% of the dollar amount of the Statement of Intention
will be held in escrow by the Transfer Agent in the name of the purchaser.  The
effective date of a Statement of Intention may be back-dated up to 90 days, in
order that any investments made during this 90-day period, valued at the
purchaser's cost, can be applied to the fulfillment of the Statement of
Intention goal.

        The Statement of Intention does not obligate the investor to purchase,
nor the Fund to sell, the indicated amount.  In the event the investment goal
is not achieved within the thirteen-month period, the purchaser is required to
pay the front end sales charge that would otherwise have applied to the
purchases of Class A shares made during this period.  If a payment is due under
the preceding sentence, it must be made directly to the Distributor within
twenty days of notification or, if not paid, the Distributor will liquidate
sufficient escrowed shares to obtain such difference.  Certain transitional
rules apply to shareholders who had a statement of intention in effect prior to
April 1, 1994. For additional information, shareholders should contact the
Fund, Wood Logan or eligible securities dealers.

        GROUP PURCHASES.  Subject to applicable regulations, reduced front end
sales charges as set forth in the "Class A Sales Charge Schedule" are available
on the purchase of Class A shares when sales are made to a group of individuals
in such a manner as results in a savings of sales expenses.  Approval of group
purchase reduced front end sales charge plans is subject to the discretion of
the Distributor.

        CERTAIN QUALIFIED PURCHASERS.  No front end sales charge or CDSC is
applicable to any sale of Class A shares to a Trustee or officer of the Fund,
or to the immediate families (i.e., the spouse, children, mother or father) of
such persons, or any full-time employee or registered representative of
broker/dealers having Dealer Agreements with the Distributor ("Selling Broker")
and their immediate families (or any trust, pension, profit sharing or other
benefit plan for the benefit of such persons), or any full-time employee of a
bank, savings and loan, credit union or other financial institution that
utilizes a Selling Broker to clear purchases of Fund shares, and their
immediate families.  In addition, no front end sales charge or CDSC is
applicable on any sale to North American Security Life Insurance Company or any
of its affiliates, the Subadvisers or Wood Logan, or to a director, officer,
full-time employee or sales representative of North American Security Life
Insurance Company or any of its affiliates, the Subadvisers or any of their
affiliates or of Wood Logan, or to the immediate families of such persons, or
any trust, pension, profit-sharing or other benefit plan for the benefit of
such persons.

        No front end sales charge or CDSC on Class A shares is applicable to
continuing purchase payments made in connection with Code Section 401 qualified
plans that were invested in the Fund prior to April 1, 1994.

        A qualified retirement plan that is currently a shareholder of the Fund
may make additional purchases of Class A shares at net asset value (i.e.,
without the imposition of a front end sales load or CDSC). A commission or
transaction fee of 1.00% will be paid by the Distributor to broker-dealers,
banks and other financial service firms subject to a chargeback to the firm for
redemptions made within one year from the date of purchase.

        Class A shares may be purchased at net asset value by certain
broker-dealers and other financial institutions which have entered into an
agreement with the Distributor, which includes a requirement that such shares
be sold for the benefit of clients participating in a "wrap account" or a
similar account program under which such clients pay a fee to such
broker-dealer or other financial institution.  Class A shares may also be
purchased at net asset value by registered investment advisers for the benefit
of client accounts if the adviser charges a fee (other than brokerage
commissions) for his services.

CLASS B SHARES

        Class B shares are offered for sale at net asset value, and are offered
for purchases of $250,000 or less.  Class B shares which are redeemed within
six years of purchase are subject to a CDSC at the rates set forth in the table
below, charged as a percentage of the dollar amount subject thereto.  See
"PURCHASES OF SHARES - Contingent Deferred Sales Charge."

</TABLE>


        The CDSC may be waived on certain redemption of shares.  See "PURCHASES
OF SHARES - Waiver of CDSC"

CLASS C SHARES

        Class C shares are offered for sale at net asset value and are offered
for purchases of less than $1 million.  Class C shares are sold without a front
end sales charge.  Class C shares purchased on or after May 1, 1995 subject to
a CDSC of 1% of the dollar amount subject thereto during the first year after
purchase.  Shares purchased prior to May 1, 1995 are not subject to a CDSC. See
"PURCHASES OF SHARES - Contingent Deferred Sales Charge"

        The CDSC may be waived on certain redemptions of shares.  See
"PURCHASES OF SHARES - Waiver of CDSC."

CONTINGENT DEFERRED SALES CHARGE

        Class A shares (purchases of $1 million or more) and Class C shares
purchased on or after May 1, 1995 which are redeemed within one year of
purchase are subject to a CDSC at the rate of 1% of the dollar amount subject
thereto.  Class B shares which are redeemed within six years of purchase are
subject to a CDSC at the rates set forth above under "PURCHASES OF SHARES -
Class B Shares."  The CDSC generally is not applicable with respect to
redemption of shares of the Money Market Fund.  However, in the case of shares
of the Money Market Fund which were obtained through an exchange of the same
class of shares of another Portfolio, such shares will be subject to any
applicable CDSC due at redemption.  Similarly, shares initially purchased as
shares of the Money Market Fund which are subsequently exchanged for the same
class of shares of other Portfolios will be subject to any applicable CDSC due
at redemption.  See "SHAREHOLDER SERVICES - Exchange Privilege."  The CDSC is
assessed on an amount equal to the lesser of the net asset value at redemption
or the initial purchase price of the shares being redeemed.  Solely for
purposes of determining the amount of time from the purchase of shares until
redemption, all orders accepted during a month are aggregated and deemed to
have been made on the last business day of that month.

        In determining the amount of the CDSC that may be applicable to a
redemption, the calculation is determined in the manner that results in the
lowest possible rate being charged.  Therefore, any shares in the redeeming
shareholder's account that may be redeemed without charge will be assumed to be
redeemed prior to those subject to a charge.  In addition, if the CDSC is
determined to be applicable to 

                                      54

<PAGE>   61

redeemed shares, it will be assumed that shares held for the longest
duration are redeemed first.  No CDSC is imposed on (i) amounts representing
increases in the net asset value per share; or (ii) shares acquired through
reinvestment of income dividends or capital gains distributions.  Because
shares of the Money Market Fund are not subject to any distribution or service
fees, the CDSC period is tolled for any period of time in which shares are held
in that Portfolio.  For example, if Class C shares of a Portfolio other than
the Money Market Fund are exchanged for the same class of shares of the Money
Market Fund six months after purchase and are subsequently redeemed one year
later, these shares are subject to a CDSC since the CDSC period is tolled
during the period of time the shares are in the Money Market Fund. Furthermore,
when Money Market Fund shares are exchanged for the same class of shares of any
other Portfolio, the CDSC becomes (or, in the case of Money Market Fund shares
which were subject to a CDSC prior to a previous exchange for Money Market Fund
shares, again becomes) applicable to those shares commencing at the time of
exchange. If such shares are subsequently redeemed, only time of ownership
spent in Portfolios other than the Money Market Fund counts toward determining
the applicable CDSC.

WAIVER OF CDSC

     SYSTEMATIC WITHDRAWAL PLAN.  The CDSC on Class A, Class B and Class C
shares may be waived in connection with a Systematic Withdrawal Plan.  See
"SHAREHOLDER SERVICES - Systematic Withdrawal Plan."  Up to 12% of the value of
an account (i.e., up to 1% per month of the value of the account at the time
the systematic withdrawal is taken) may be withdrawn without the imposition of
CDSC.  If distributions (dividends and capital gains) are reinvested into an
account and systematic withdrawals are also taken from the account, the
distributions (which are never assessed a CDSC) will be included in the
calculation of the 1% per month that may be withdrawn without the imposition of
a CDSC.

     QUALIFIED RETIREMENT PLANS.  The CDSC on Class A, Class B and Class C
shares may be waived in connection with redemptions from qualified retirement
plans (other than Individual Retirement Accounts ("IRAs")) in the case of (i)
death or disability (as defined in section 72(m)(7) of the Code, as amended
from time to time) of the participant in the retirement plan, (ii) required
minimum distributions from the retirement plan due to attainment of age 70 1/2,
(iii) tax-free return of an excess contribution to the retirement plan, (iv)
retirement of the participant in the retirement plan, (v) a loan from the
retirement plan (repayment of a loan, however, will constitute a new sale for
purposes of assessing the CDSC), (vi) "financial hardship" of the participant
in the retirement plan, as that term is defined in Treasury Regulation
1.401(k)-1(d)(2), as amended from time to time, and (vii) termination of
employment of the participant in the plan (excluding, however, a partial or
other termination of the retirement plan).

     OTHER WAIVERS.  The CDSC on Class A, Class B and Class C shares may be
waived in connection with (i) redemptions made following the death of a
shareholder, (ii) redemptions effected pursuant to the Fund's right to
liquidate a shareholder's account if the aggregate net asset value of the
shares held in the account is less than the applicable minimum account size and
(iii) a tax-free return of an excess contribution to any retirement plan.

OTHER DEALER COMPENSATION

     The Distributor may, either directly or through Wood Logan, from time to
time assist dealers by, among other things, providing sales literature to, and
holding educational programs for the benefit of, dealers' registered
representatives.  Participation of registered representatives in such
informational programs may require the sale of minimum dollar amounts of shares
of the Portfolios of the Fund.  The Distributor and/or Wood Logan will also
provide additional promotional incentives to dealers in connection with sales
of shares of all classes of the Portfolios of the Fund.  These incentives shall
include payment for travel expenses, including lodging (which may be at a
luxury resort), incurred in connection with trips taken by qualifying
registered representatives and members of their families within or outside the
United States.  Incentive payments will be provided for out of the front end
sales charges and CDSCs retained by the Distributor, any applicable
Distribution Plan payments or the Distributor's other resources.  Other than
Distribution Plan payments, the Fund does not bear distribution expenses.  The
staff of the SEC has indicated that dealers who receive more than 90% of the
sales charge may be considered underwriters.

DISTRIBUTION EXPENSES

     In addition to the front-end sales charge which may be deducted at the
time of purchase of Class A shares of less than $1 million and the CDSC which
may apply on redemptions of Class A shares (purchases of $1 million or more),
Class B shares, and Class C shares, each class of shares of each Portfolio is
authorized under the Distribution Plan applicable to that class of shares (the
"Class A Plan," the "Class B Plan" and the "Class C Plan," collectively, the
"Plans") adopted pursuant to Rule 12b-1 under the 1940 Act to use the assets
attributable to such class of shares of the Portfolio to finance certain
activities relating to the distribution of shares to investors.  The Plans are
"compensation" plans providing for the payment of a fixed percentage of average
net assets to finance distribution expenses.  The Plans provide for the payment
by each class of shares of each Portfolio of the Fund, other than the Money
Market Fund, of a monthly distribution and service fee to the Distributor, as
principal underwriter for the Fund.  Portions of the fees prescribed below are
used to provide payments to the Distributor, to promotional agents, to brokers,
dealers or financial institutions (collectively, "Selling Agents") and to
Service Organizations for ongoing account services to shareholders and are
deemed to be "service fees" as defined in paragraph (b)(9) of Section 26 of the
Rules of Fair Practice of the NASD.

                                       55

<PAGE>   62


     Under the Class A Plan, Class A shares of each Portfolio (except as
described in the next sentence) are subject to a fee of up to .35% of their
respective average annual net assets, five-sevenths of which (.25%) constitutes
a "service fee."  Class A shares of the Money Market Fund bear no such fees and
Class A shares of the National Municipal Bond Fund are subject to a fee of up
to .15% of Class A average annual net assets, the entire amount of which
constitutes a "service fee."  Under the Class B Plan, Class B shares of each
Portfolio (with the exception of the Money Market Fund) are subject to a fee of
up to 1.00% of their respective average annual net assets, one-fourth (.25%) of
which constitutes a "service fee."  Under the Class C Plan, Class C shares of
each Portfolio (with the exception of the Money Market Fund) are subject to a
fee of up to 1.00% of their respective average annual net assets, one-fourth
(.25%) of which constitutes a "service fee."

     Payments under the Plans are used primarily to compensate the Distributor
for distribution services provided by it in connection with the offering and
sale of the applicable class of shares, and related expenses incurred,
including payments by the Distributor to compensate or reimburse Selling Agents
for sales support services provided and related expenses incurred by such
Selling Agents.  Such services and expenses may include the development,
formulation and implementation of marketing and promotional activities, the
preparation, printing and distribution of prospectuses and reports to
recipients other than existing shareholders, the preparation, printing and
distribution of sales literature, expenditures for support services such as
telephone facilities and expenses and shareholder services as the Fund may
reasonably request, provision to the Fund of such information, analyses and
opinions with respect to marketing and promotional activities as the Fund may,
from time to time, reasonably request, commissions, incentive compensation or
other compensation to, and expenses of, account executives or other employees
of the Distributor or Selling Agents, attributable to distribution or sales
support activities, respectively, overhead and other office expenses of the
Distributor or Selling Agents, attributable to distribution or sales support
activities, respectively, and any other costs and expenses relating to
distribution or sales support activities.  The Distributor may pay directly
Selling Agents and may provide directly the distribution services described
above, or it may arrange for such payment or the performance of some or all of
such services by Wood Logan, the Fund's exclusive promotional agent, at such
level of compensation as may be agreed to by the Distributor and Wood Logan.

     The Distributor currently pays a trail commission to securities dealers,
with respect to accounts that such dealers continue to service for shares sold
after April 1, 1994 as follows: Class A shares - .25% annually,commencing from
the date the purchase order is accepted, for all Portfolios (except the
National Municipal Bond Fund, for which the trail commission is .15%, and the
Money Market Fund, for which no trail commission is paid); Class B shares -
 .25% annually, for all Portfolios (except the National Municipal Bond Fund, for
which the trail commission is .15%, and the Money Market Fund, for which no
trail commission is paid); and Class C shares - 1.0% annually, for the Global
Growth, Growth, Growth and Income, International Growth and Income, Asset
Allocation and Strategic Bond Funds and .90% annually,  for the Investment
Quality Bond, U.S. Government Securities and National Municipal Bond Fund (no
trail commission is paid on the Money Market Fund). The trail commission
payable following conversion of Class B and Class C shares to Class A shares
will be in accordance with the amounts paid for Class A shares.  For Class B
and Class C shares sold on or after May 1, 1995, trail commisssions commence 13
months after purchase.  For Class B and Class C shares sold prior to May 1,
1995, trail commissions commence the date the purchase order is accepted.
Trail  commissions for shares sold prior to April 1, 1994 will be paid as noted
below.

     In the case of Class B shares and Class C shares sold on or after May 1,
1995, the Distributor will advance to securities dealers the first year service
fee at a rate equal to 0.25% of the purchase price of such shares and, as
compensation therefor, the Distributor may retain the service fee paid by the
Fund with respect to such shares for the first year after purchase.  In the
case of sales of Class B shares, the Distributor will pay each dealer a fee of
4% of the amount of Class B shares purchased (0.25% is the advancement of the
first year service fee and the remainder is a commission or transaction fee).
No commission or transaction fee is paid for sales of shares of Class B of the
Money Market Fund.  In the case of sales of Class C shares, the Distributor
will pay each securities dealer a fee of 1% (0.90% in the case of the
Investment Quality Bond, U.S. Government Securities and National Municipal Bond
Fund) of the purchase price of Class C shares purchased through such securities
dealer (0.25% is the advancement of the first year service fee and the
remainder is a commission or transaction fee).  No commission or transaction
fee is paid for sales of shares of Class C of the Money Market Fund.

     The Distributor will also pay a trail commission to securities dealers,
with respect to accounts that such dealers continue to service for shares sold
prior to April 1, 1994, as follows: (i) for the Growth, Growth and Income,
Global Growth and Asset Allocation Funds, 0.90%, (ii) for the U.S. Government
Securities, Investment Quality Bond and Strategic Income Funds, 0.35% and for
the National Municipal Bond Fund, 0.15%.  No trail commission will be paid on
shares of the Money Market Fund.  The trail commission above will be paid on
shares purchased prior to April 1, 1994 provided the shares remain in the same
Portfolio.  If the shares are exchanged or transfered from the Portfolio at any
time on or after April 1, 1994, then the trail commission for shares sold after
April 1, 1994 as stated above will be paid.

     The distribution and service fees attributable to the Class B shares and
the Class C shares are designed to permit an investor to purchase shares
without the assessment of a front end sales charge, and, with respect to the
Class C shares, without the assessment of a CDSC as well, and at the same time
permit the Distributor to compensate securities dealers with respect to sales
of such shares.

     The Distributor is authorized by each Plan to retain any excess of the
fees it receives thereunder over its payments to selected dealers or Wood Logan
and its expenses incurred in connection with providing distribution services.
Thus, payments under a Plan may result in a profit to the Distributor.  Each
Plan also provides that to the extent that any payments by any class of any
Portfolio of the Fund to 

                                       56

<PAGE>   63
the Distributor in its capacity as investment adviser to the Fund, such
as for investment management fees, may be deemed to be an indirect payment of
distribution expenses, those indirect payments are deemed to be authorized by
the Plans.  Payments made under the Plans are subject to quarterly review by
the Trustees and the Plans are subject to annual review and approval by the
Trustees.

     In adopting the Plans, the Trustees determined that the adoption of the
Plans is in the best interests of the Fund and its shareholders, that there is
a reasonable likelihood that the Plans will benefit the Fund and its
shareholders, and that the Plans are essential to, and an integral part of, the
Fund's program for financing the sale of shares of the various Portfolios of
the Fund to the public.

     The Distributor, a wholly-owned subsidiary of North American Security Life
Insurance Company, is a broker/dealer registered under the Securities Exchange
Act of 1934, as amended (the "1934 Act") and is a member of the NASD.  The
Distributor's address is the same as that of the Fund and the Distributor also
serves as the investment adviser to the Fund as described above under
"MANAGEMENT OF THE FUND."  The Distributor has entered into an exclusive
promotional agent agreement with Wood Logan pursuant to which Wood Logan will
solicit securities dealers to sell Fund shares, offer sales training to
registered representatives of such dealers, prepare and distribute certain
sales and promotional materials and otherwise assist in the distribution of
Fund shares. For providing such services, the Distributor will pay Wood Logan
such amounts as are agreed to from time to time pursuant to the promotional
agent agreement.  Wood Logan, a broker/dealer registered under the 1934 Act and
a member of the NASD, is a subsidiary of Wood Logan Associates, Inc., a
corporation approximately 20% of whose stock is owned by North American Life
and its affiliates.  The address of Wood Logan is 1455 East Putnam Avenue, Old
Greenwich, Connecticut 06870.

FURTHER INFORMATION ON ANY OF THE PROGRAMS DESCRIBED IN THE FOLLOWING SECTIONS
MAY BE OBTAINED FROM THE FUND, WOOD LOGAN AND ELIGIBLE SECURITIES DEALERS.  FOR
ADDITIONAL INFORMATION, SHAREHOLDERS SHOULD CONTACT THE FUND, WOOD LOGAN OR
ELIGIBLE SECURITIES DEALERS.

AUTOMATIC INVESTMENT PLAN

     Shareholders who open an account who wish to make subsequent monthly
investments in a Portfolio may establish an Automatic Investment Plan as part
of the initial Application or subsequently by submitting an Application.  Under
this plan, on or about the tenth day of each month the Transfer Agent will
debit the shareholder's bank account in the amount specified by the shareholder
(which monthly amount may not be less than $50).  The proceeds will be invested
in shares of the specified class of a Portfolio of the Fund at the applicable
offering price determined on the date of the debit.  In the event of a full
exchange, this plan will follow into the new Portfolio unless otherwise
specified. Participation in the Automatic Investment Plan may be discontinued
upon 30 days' written notice to the Transfer Agent, or if a debit is not
honored.

EXCHANGE PRIVILEGE

     Shares of any Portfolio may be exchanged for shares of the same class of
any other Portfolio with the same account registration at the relative net
asset value per share without the imposition of any front end sales charge or
CDSC, except as described below.  Shares of one class may not be exchanged for
shares of any other class of any Portfolio.

     CLASS A SHARES - Class A shares of any Portfolio may be exchanged for
Class A shares of any other Portfolio at the relative net asset value per share
without the imposition of a front end sales charge or CDSC which would be due
upon redemption with respect to the shares being exchanged.  However, a front
end sales charge will be imposed with respect to Class A shares (purchases of
less than $1 million) which are issued upon an exchange from Class A Money
Market Fund shares and as to which no front end sales charge had been
previously paid or waived.  See "SHAREHOLDER SERVICES - Money Market Fund -
Assessment of CDSC."

     CLASS B SHARES - Class B shares of any Portfolio may be exchanged for
Class B shares of any other Portfolio, including the Money Market Fund, at the
relative net asset value per share without the imposition at that time of any
CDSC which would be due upon redemption with respect to the shares being
exchanged.  See "SHAREHOLDER SERVICES - Money Market Fund - Assessment of
CDSC."

     CLASS C SHARES - Class C shares of any Portfolio may be exchanged for
Class C shares of any other Portfolio, including the Money Market Fund, at the
relative net asset value per share without the imposition at that time of any
CDSC which would be due upon redemption with respect to the shares being
exchanged. See "SHAREHOLDER SERVICES - Money Market Fund - Assessment of CDSC."

     MONEY MARKET FUND - ASSESSMENT OF CDSC - The CDSC period for Class A
shares (purchases of $1 million or more), Class B shares and Class C shares is
tolled for any period of time in which they are held in the Money Market Fund.
For example, if Class C shares of a Portfolio, other than the Money Market
Fund, are exchanged for Class C shares of the Money Market Fund six months
after purchase and are subsequently redeemed one year later, these Class C
shares are subject to a CDSC since the CDSC period is tolled during the period
of time the shares are in the Money Market Fund.  Furthermore, when Money
Market Fund shares are exchanged for shares of any other 

                                       57

<PAGE>   64
Portfolio, the CDSC becomes (or, in the case of Money Market Fund
shares which were subject to a CDSC prior to a previous exchange for Money
Market Fund shares, again becomes) applicable to those shares commencing at the
time of exchange.  If such shares are subsequently redeemed, only time of
ownership spent in Portfolios other than the Money Market Fund counts toward
determining the applicable CDSC.

     GENERAL INFORMATION - Exchanges are regarded as sales for federal and
state income tax purposes and could result in a gain or loss, depending on the
original cost of shares exchanged. If the exchanged shares were acquired within
the previous 90 days, the gain or loss may have to be computed without regard
to any sales charges incurred on the exchanged shares (except to the extent
those sales charges exceed the sales charges waived in connection with the
exchange).  See "GENERAL INFORMATION -- Taxes."  Exchanges are free and
unlimited in number and will usually occur on the same day as requested.  The
terms of the foregoing exchange privilege are subject to change and the
privilege may be terminated at any time.  The exchange privilege is only
available where the exchange may legally be made.

     BY MAIL - an exchange will be honored by a written letter of request to
the Fund if signed by all registered owners of the account.

     BY TELEPHONE - All accounts are eligible for the telephone exchange
privilege.  See "-- ADDITIONAL SHAREHOLDER PRIVILEGES -- Telephone Exchanges."

TRANSFER OF SHARES

     Shareholders may transfer fund shares to family members and others at any
time without incurring a front end sales charge (Class A shares purchases of
less than $1 million) and without a CDSC being imposed at that time (Class A
shares purchases of $1 million or more, Class B shares and Class C shares).
Shareholders should consult their tax adviser concerning such transfers.

REDEMPTION OF SHARES

     You may redeem shares of your account in any amount and at any time at the
applicable net asset value next determined after the request for redemption is
received in proper order by the Fund.  As described under "PURCHASE OF SHARES,"
redemptions of Class A shares purchases of $1 million or more, Class B shares
and Class C shares may subject to a CDSC.  The Fund will normally send the
proceeds from a redemption (less any applicable CDSC) on the next business day,
but if making immediate payment could adversely affect the Fund, it may take up
to seven days for payment to be made.  Payment may also be delayed if the
shares to be redeemed were purchased by check and that check has not cleared.

GENERAL METHODS OF REDEEMING SHARES

     1. BY MAIL. You may redeem shares by mail by sending a written request for
the redemption to the Fund.  The request will be processed after receipt of all
required documents in proper order: certificates of beneficial interest (if
issued); a stock power signed by all account owners exactly as the account is
registered specifying the number of shares or dollars to be redeemed; and in
the case of a redemption to be paid to a person or address other than the
person or address of record and/or in an amount greater than $50,000, a
guarantee of the stock power signatures(s) without restriction, condition or
qualification by an officer of a commercial bank, Trust Company, Federal
savings and loan institution, member firm of a national securities exchange or
NASD member.  If shares are held in the name of a corporation, trust, estate,
custodianship, partnership or pension or profit sharing plan, additional
documentation may be necessary.

     2. THROUGH A SECURITIES DEALER. You may sell your shares by contacting a
securities dealer who has a Dealer Agreement with the Distributor.  (See
"GENERAL -- Repurchase of Shares" in the Statement of Additional Information
for more details.) The dealer may assess a nominal fee for this service.

REINSTATEMENT PRIVILEGE

     With regard to Class A shares (purchases of less than $1 million), you may
reinstate at net asset value any portion of shares which have been previously
redeemed if the redemption occurred within 90 days of the request.  With regard
to Class A shares (purchases of $1 million or more), Class B shares and Class C
shares, if an investor redeems these shares and pays a CDSC upon redemption,
and then uses those proceeds to purchase the same class of shares of any
Portfolio within 90 days, the shares purchased will be credited with any CDSC
paid in connection with the prior redemption.

     Any gain recognized on a redemption or repurchase is taxable despite the
reinstatement in the Portfolio.  Any loss realized as a result of the
redemption or repurchase may not be allowed as a deduction for federal income
tax purposes but may be applied, depending on the amount reinstated, to adjust
the cost basis of the shares acquired upon reinstatement.  In addition, if the
shares redeemed or repurchased had been acquired within the 90 days preceding
the redemption or repurchase, the amount of any gain or loss on the redemption
or repurchase may have to be computed without regard to any sales charges
incurred on the redeemed or repurchased shares (except to the extent those
sales charges exceed the sales charges waived in connection with the
reinstatement).  See "GENERAL INFORMATION -- Taxes."

MINIMUM ACCOUNT BALANCE

     The Fund reserves the right to involuntarily redeem your account any time
the value of your account falls below $500 as a result of redemption, with the
exception of a retirement plan account and with respect to an account
established with a minimum of $50 pursuant to programs such as Automatic
Investment Plans, Automatic Dividend Diversification, and Systematic Investing.
You will be notified in writing prior to the redemption and be allowed 30 days
to make additional investments before the redemption is processed.

REDEMPTION IN KIND

     The Trustees of the Fund reserve the right to redeem proceeds in whole or
in part by a distribution in kind of marketable securities held by a Portfolio
of the Fund.  See "GENERAL -- Redemption in Kind" in the Statement of
Additional Information for more details.

ADDITIONAL SHAREHOLDER PRIVILEGES

CERTAIN PRIVILEGES LISTED IN THIS SECTION MAY NOT BE OFFERED BY THE FUND IF YOU
HOLD SHARES WITH THE FUND IN THE "STREET NAME" OF A FINANCIAL INSTITUTION, OR
IF THE ACCOUNT IS NETWORKED THROUGH NATIONAL SECURITIES CLEARING CORPORATION
(NSCC).

AUTOMATIC INVESTMENT PLAN

     If you open an account and wish to make subsequent, periodic investments
in a Portfolio by electronic funds transfer from a bank account, you may
establish an Automatic Investment Plan on your account.  The bank at which your
account is maintained must be a member of the Automated Clearing House (ACH).
The frequency with which the investments occur is specified by you (monthly,
every alternate month, quarterly, etc.) with the exception that no more than
one investment will be processed each month.  On or about the tenth of the
month, the Fund will debit your bank account in the specified amount (minimum
of $50 per draft) and the proceeds will be invested at the applicable offering
price determined on the date of the debit.  In the event of a full exchange,
this plan will follow into the new Portfolio unless otherwise specified.

AUTOMATIC DIVIDEND DIVERSIFICATION (ADD)

     The ADD program allows you to have all dividends and any other
distributions from a Portfolio automatically used to purchase shares of the
same class of any other Portfolio of the Fund.  The receiving account must be
in the same name as your existing account.  The purchase of shares to the
Portfolio receiving the cross-investment of the dividends will be using the net
asset value at the close of business of the dividend payable date.

SYSTEMATIC INVESTING

     You may request that your shares of any class of the Money Market, U.S.
Government Securities or National Municipal Bond Fund be exchanged monthly for
shares of the same class of up to three other Portfolios.  A predetermined
dollar amount of at least $50 per exchange will then occur on or about the 15th
of each month in accordance with the instructions you provided on the initial
account application or on the Systematic Investing application.  This
Systematic Investing program is also referred to as "Dollar Cost Averaging."

SYSTEMATIC WITHDRAWAL PLAN

     You may establish a plan for redemptions to be made automatically at
monthly, quarterly, semiannual or annual intervals with payments sent directly
to you or to persons designated by you as recipients of the withdrawals.  Up to
12% of the value of an account (i.e., up to 1% per month of the value of the
account at the time the Systematic Withdrawal is taken) may be withdrawn
without the imposition of CDSC.  See "PURCHASES OF SHARES - Waiver of CDSC."
Requests for this service not made on the initial application require signature
guarantees unless the payments are to be made to you and mailed to the address
of record on your account.  You are required to have a minimum account value of
$10,000 per Portfolio in order to establish this plan.  Maintenance of a
Systematic Withdrawal Plan concurrently with purchases of additional shares may
be disadvantageous to you because of the sales charges on certain purchases and
redemptions.

     The redemptions will occur on or about the 25th day of the month and the
checks will generally be mailed within two days after the redemption occurs.
No redemption will occur if the account balance falls below the amount required
to meet the requested withdrawal amount.  This service may be terminated at any
time, and, while no fee is currently charged (although a CDSC may be
applicable), the Distributor reserves the right to initiate a fee of up to $5
per withdrawal upon 30 days' written notice to the shareholder.

CHECKWRITING

     Checkwriting is available only to Class A and Class C shareholders of the
U.S. Government Securities, National Municipal Bond and Money Market Funds.
You will be issued a book of blank checks if the request is indicated on the
account application and is accompanied by a correctly completed and endorsed
signature card.  The checks may be made payable to the order of anyone in any
amount not less than $250.  You should not attempt to close your account by
check.

     Checks which exceed the value of the account at the time of receipt by the
Fund will not be honored.  In addition, the privilege will be invalid when your
account is closed.

     When a check is presented for payment, a sufficient number of shares will
be redeemed to cover the amount of the check and any applicable CDSC.  If the
amount of the check plus any applicable CDSC is greater than the value of the
shares held in the shareholder's account, the check will be returned unpaid.

     This privilege cannot be used for the redemption of shares held in
certificate form.

TELEPHONE TRANSACTIONS

     Shareholders are permitted to request exchanges and/or redemptions by
telephone.  The Fund will not be liable for following instructions communicated
by telephone that it reasonably believes to be genuine.  The Fund will employ
reasonable procedures to confirm that instructions communicated by telephone
are genuine and may only be liable for any losses due to unauthorized or
fraudulent instructions where it fails to employ its procedures properly.  Such
procedures include the following.  Upon telephoning a request, shareholders
will be asked to provide their account number, and if not available, their
social security number.  For the shareholder's and Fund's protection, all
conversations with shareholders will be tape recorded.  All telephone
transactions will be followed by a confirmation statement of the transaction.

     TELEPHONE EXCHANGES.  You are automatically authorized to effect telephone
exchanges by calling the Fund, unless you elect not to authorize telephone
exchanges in the Application (if you initially elect not to allow telephone
exchanges in the Application, you may request authorization by executing an
appropriate authorization form provided by the Fund upon request.) Exchanges
will only be made if proper account identification is given by the dealer or
shareholder of record.  Requests will be processed on the same day as receipt
of the telephone call if the request is made before the close of the regularly
scheduled trading on the Exchange (normally 4:00 p.m. New York time).

     This privilege cannot be used for the exchange of shares held in
certificate form.

     TELEPHONE REDEMPTIONS.  You may request the option to redeem shares of any
Portfolio by telephone by completing the "Expedited Telephone Redemptions"
portion of the account application.  In order to obtain that day's closing net
asset value on the redemption, the telephone call must be received by the Fund
prior to the close of the regularly scheduled trading on the Exchange (normally
4:00 p.m. New York time).

     Payment for shares will be made by federal wire or by mail as specified by
you in the Application.  Payment will normally be sent on the business day
following the date of receipt of the request. Payment by wire to your bank
account must be in amounts of $1000 or more.

     Although the Fund does not assess a charge for wire transfers, your bank
may assess a charge for the transaction. Payments by mail may only be sent to
your account address of record and may only be payable to the registered
owner(s).

     This privilege cannot be used for the redemption of shares held in
certificate form.

CERTIFICATES

     Although the Fund does not recommend the issuance of certificates, shares
will be issued in certificate form if specifically requested by the
shareholder.

HOW TO OBTAIN INFORMATION ON YOUR INVESTMENT
                           
     1.  CONFIRMATION OF SHARE TRANSACTIONS AND DIVIDEND PAYMENTS.
     Share transactions in all Portfolios, other than transactions pursuant to
a Systematic Withdrawal Plan, Automatic Investment Plan, and Systematic
Investing Plan, will be confirmed immediately in the form of an account
confirmation statement which will be mailed to the account address of record.


                                       60
<PAGE>   67

     The Fund will confirm all account activity occurring within a calendar
quarter, including the payment of dividend and capital gain distributions and
transactions made as a result of a Systematic Withdrawal Plan, Automatic
Investment Plan, and Systematic Investing Plan, shortly after the end of each
calendar quarter.

     The Fund also reserves the right to confirm, with respect to certain tax
qualified plans and certain group plans, purchases and sales of Fund shares on
a quarterly basis.  Transactions in shares of the Money Market Fund, other than
those confirmed quarterly as set forth above, will be confirmed monthly.

     A copy of all confirmation statements will be sent to the securities
dealer firm listed on your account.

     2.  SHAREHOLDER INQUIRIES.  Please direct any questions or requests that
you may have concerning the Fund or your account by writing to North American
Funds, P.O. Box 8505, Boston, Massachusetts 02266-8505, or by calling the

                            DEBT SECURITY RATINGS

Standard & Poor's Ratings Group ("S&P")
- -------------------------------
Commercial Paper:

<TABLE>
<S>    <C>
A-1    The rating A-1 is the highest rating assigned by S&P to commercial
       paper.  This designation indicates that the degree of safety regarding
       timely payment is either overwhelming or very strong.  Those issues
       determined to possess overwhelming safety characteristics are denoted
       with a plus (+) sign designation.

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


Bonds:

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 higher rated issues 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 the 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 Bonds rated BB, B, CCC and CC are regarded, on balance, as
       predominantly speculative with respect to the issuer's capacity to pay
       interest and repay principal in accordance with the terms of the
       obligations.  BB indicates the lowest degree of speculation and CC the
       highest degree of speculation.  While such bonds will likely have some
       quality and protective characteristics, these are outweighed by large
       uncertainties or major risk exposures to adverse conditions.

D      Bonds rated D are in default.  The D category is used when interest
       payments or principal payments are not made on the date due even if the
       applicable grace period has not expired.  The D rating is also used upon
       the filing of a bankruptcy petition if debt service payments are
       jeopardized.
</TABLE>

The ratings set forth above may be modified by the addition of a plus or minus
to show relative standing within the major rating categories.


Moody's Investors Service, Inc. ("Moody's")
- -------------------------------
Commercial Paper:

<TABLE>
<S>    <C>
P-1    The rating P-1 is the highest commercial paper rating assigned by
       Moody's.  Issuers rated P-1 (or related supporting institutions) have a
       superior capacity for repayment of short-term promissory obligations.
       P-1 repayment capacity will normally be evidenced by the following
       characteristics:  (1) leading market positions in established
       industries; (2) high rates of return on funds employed; (3) conservative
       capitalization structures with moderate reliance on debt and ample asset
       protection; (4) broad margins in earnings coverage of fixed financial
       charges and high internal cash generation; and (5) well established
       access to a range of financial markets and assured sources of alternate
       liquidity.

P-2    Issuers rated P-2 (or related supporting institutions) have a strong
       capacity for repayment of short-term promissory 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, will
       be more subject to variation.  Capitalization characteristics, while
       still appropriate, may be more affected by external conditions.  Ample
       alternative liquidity is maintained.
</TABLE>

                                      A-1

<PAGE>   69

Bonds: 

<TABLE>
<S>    <C>
Aaa    Bonds which are rated Aaa by Moody's 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 by Moody's 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 risks appear somewhat larger than in Aaa securities.

A      Bonds which are rated A by Moody's 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 sometime in the future.

Baa    Bonds which are rated Baa by Moody's are considered as medium grade
       obligations, that is, 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.

B      Bonds which are rated B generally lack characteristics of a desirable
       investment.  Assurance of interest  and principal payments or of
       maintenance and 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
       high degree.  Such issues are often in default or have other marked
       shortcomings.

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


Moody's applies numerical modifiers "1", "2" and "3" to certain of its rating
classifications.  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 issue ranks in the
lower end of its generic rating category.


Fitch Investors Service, Inc. ("Fitch")
- -----------------------------
Commercial Paper:

<TABLE>
<S>     <C>
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     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+" or "F-1".

Bonds:

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.
</TABLE>



                                      A-2

<PAGE>   70

<TABLE>
<S>     <C>
AA      Bonds considered to be investment grade and of very 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 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 repay principal is
        considered to be adequate.  Adverse changes in economic conditions and
        circumstances, however, are more likely to have 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       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- Bonds are in default on interest and/or principal payments.  Such bonds
and D   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.

</TABLE>

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 "AAA" category.

MOODY'S RATINGS OF STATE AND MUNICIPAL NOTES

<TABLE>
<S>                  <C>
MIG-1/VMIG-1         Notes rated MIG-1/VMIG-1 are of the best quality.  There
                     is present strong protection by established cash flows,
                     superior liquidity support or broad-based access to the
                     market for refinancing.

MIG-2/VMIG-2         Notes which are rated MIG-2/VMIG-2 are of high quality.
                     Margins of protection are ample though not so large as in
                     the preceding group.

S&P RATINGS OF STATE AND MUNICIPAL NOTES

SP-1                 Notes which are rated SP-1 have a very strong or strong
                     capacity to pay principal and interest.  Those issues
                     determined to possess overwhelming safety characteristics
                     will be given a plus (+) designation.

SP-2                 Notes which are rated SP-2 have a satisfactory capacity to
                     pay principal and interest.
