                                                            November      , 1996
 
                          TO OUR VARIABLE ANNUITY AND
                         VARIABLE LIFE CONTRACT OWNERS:
 
     A Special Meeting of Shareholders of the Manulife Series Fund, Inc. ("MSF")
will be held at the offices of NASL Series Trust at 116 Huntington Avenue,
Boston, Massachusetts 02116, on December 20, 1996, at 10:00 a.m., Eastern
Standard Time, for the purpose of considering a reorganization proposal that
will combine each of the nine MSF funds, which are managed by an investment
adviser controlled by The Manufacturers Life Insurance Company ("Manulife"),
with an existing or newly-created fund in NASL Series Trust ("NASL"), a mutual
fund group that is advised by another investment adviser controlled by Manulife.
There are certain differences between the investment objectives, policies and
restrictions of the MSF funds and the corresponding NASL funds, as summarized in
the tables beginning on page six and included under the caption "Comparison of
Investment Objectives and Policies" in the enclosed Prospectus/Proxy Statement.
 
     Although you are not a shareholder of MSF, your purchase payments and the
earnings on such purchase payments under your variable annuity or variable life
contract issued by The Manufacturers Life Insurance Company of America
("Manufacturers Life of America") are invested in shares of one or more of the
MSF funds through sub-accounts of separate accounts established by Manufacturers
Life of America for such purpose. Since the value of your contract depends in
part on the investment performance of MSF shares, you have the right to instruct
Manufacturers Life of America as to the manner in which MSF shares attributable
to your contract are voted. The number of votes as to each MSF fund for which
you may give instructions is determined by dividing your contract value (or the
reserve for a contract after its maturity date) allocated to the sub-account in
which such MSF fund shares are held by the value per share of that MSF fund.
Fractional votes are counted. MSF shares held in each sub-account as to which no
instructions are received, including shares not attributable to contractholders,
will be voted in the same proportion as shares in that sub-account for which
instructions are received from contractholders.
 
     The reorganization will provide contractholders a multiple manager approach
of portfolio management under which NASL's investment adviser monitors and
evaluates subadviser performance, investment compliance and capabilities with
the goal of maintaining high quality and an appropriate balance of investment
alternatives for investors. This includes the introduction of high-profile money
managers
<PAGE>   6
 
such as Founders Asset Management, Inc., Price-Fleming International, Inc. and
Warburg, Pincus Counsellors, Inc.
 
     The reorganization also will enable contractholders to take advantage of an
investment management approach known as managing to the "Efficient Frontier" in
which investors allocate their assets among a broad mix of investment choices
consistent with their risk tolerance levels with the goal of maximizing their
risk adjusted investment return. In connection with this approach, it is
anticipated that, within 1997, most of the funds in the NASL family will be made
available as investment options in most of the variable contracts issued by
Manufacturers Life of America prior to the reorganization, providing
contractholders with direct access to a wide range of investment alternatives.
NASL intends, in early 1997, to add several asset allocation portfolios to its
fund family in connection with the expansion of the "Efficient Frontier"
investment management approach.
 
     Furthermore, as a result of the reorganization, contractholders invested in
the Manulife Money-Market Fund will be able to pursue substantially the same
investment goals in a larger NASL fund immediately, and it is anticipated that
each of the combined MSF and NASL funds will experience more rapid asset growth
in the future than would have been the case for the MSF funds standing alone,
resulting in larger funds. Such larger funds should enhance the ability of
portfolio managers to effect portfolio transactions on more favorable terms and
give portfolio managers greater investment flexibility and the ability to select
a larger number of portfolio securities, with the attendant benefits of
increased diversification.
 
     As part of this proposal, some of the fees will go up, others down. The
Board has determined that the benefits provided by the reorganization justify
the changes in fees. With respect to certain NASL funds, NASL's adviser has
agreed to limit the total expenses of such funds for a period of one year
following the reorganization to a level no higher than the total expenses borne
by the corresponding MSF funds. These arrangements are discussed in the enclosed
Prospectus/Proxy Statement. For these reasons and the additional reasons
discussed in the enclosed Prospectus/Proxy Statement, the Board of Directors of
MSF unanimously recommends that you vote FOR approval of the reorganization
proposal.
 
     The value of your investment will not be affected in the reorganization
transaction. Furthermore, in the opinion of legal counsel, the transaction will
not be subject to federal income taxes. NASL's adviser and its affiliates have
agreed to bear the expenses of the reorganization (other than registration fees
payable for the registration of shares of the NASL funds in connection with the
reorganization).
 
     Enclosed you will find a Notice of Special Meeting of Shareholders, a
Prospectus/Proxy Statement for MSF and a Voting Instructions Form for each MSF
fund in which your contract values were invested as of October 23, 1996 (the
record date for the Meeting). The number of shares of each MSF fund which
represent your voting interest determined as explained above appears on each
enclosed Voting Instructions Form. The Prospectus/Proxy Statement provides
<PAGE>   7
 
background information and explains the matters to be voted on at the Meeting.
We urge you to read it and then complete and return each Voting Instructions
Form on or before December 19, 1996.
 
     If you have any questions regarding the reorganization, please call
1-800-827-4546.

endorsed the proposals set forth in the accompanying Prospectus/Proxy Statement.
THE BOARD OF DIRECTORS OF MSF RECOMMENDS THAT SHAREHOLDERS VOTE FOR ITEM 1.
 
     Approval of the Agreement will require the affirmative vote of the holders
of at least a majority of the outstanding shares of each of the Manulife
Portfolios. By approving the Agreement, MSF shareholders will be deemed to have
waived certain of MSF's investment limitations solely insofar as they might be
deemed to apply to the transactions provided for in the Prospectus/Proxy
Statement. The Board of Directors knows of no other business that will be acted
upon at the Meeting.
 
     Each shareholder of record at the close of business on October 23, 1996 is
entitled to receive notice of and to vote at the Meeting.

               PROSPECTUS/PROXY STATEMENT DATED NOVEMBER   , 1996
 
                          Acquisition of the assets of
 
                           MANULIFE SERIES FUND, INC.

                               NASL SERIES TRUST
                             116 Huntington Avenue
                          Boston, Massachusetts 02166
                                 1-800-827-8037
 
     This Prospectus/Proxy Statement relates to the proposed transfer of all of
the assets and liabilities of the portfolios (the "Manulife Portfolios") of
Manulife Series Fund, Inc. ("MSF") to corresponding portfolios (the "NASL
Portfolios") of NASL Series Trust ("NASL") in exchange for shares of such NASL
Portfolios (the "Reorganization"). NASL is a no-load, open-end management
investment company, commonly known as a mutual fund, offering shares in several
portfolios. As a result of the Reorganization, each shareholder of a Manulife
Portfolio will receive that number of shares of the corresponding NASL Portfolio
equal in value at the time of the exchange to the value of such shareholder's
shares of the Manulife Portfolio at such date. The terms and conditions of the
Reorganization are more fully described in this Prospectus/Proxy Statement and
in the Agreement and Plan of Reorganization between MSF and NASL attached hereto
as Exhibit A.
 
     Shares of NASL are not offered directly to the public but are sold only to
insurance companies and their separate accounts as the underlying investment
medium for variable life and annuity contracts ("contracts"). As of the record
date for the Special Meeting of Shareholders, 100% of the Manulife Portfolio
shares were legally owned by The Manufacturers Life Insurance Company of America
("Manufacturers Life of America"), a stock life insurance company organized
under the laws of Pennsylvania and redomesticated under the laws of Michigan.
Manufacturers Life of America holds Manulife Portfolio shares attributable to
variable life contracts in Separate Accounts One, Three and Four and variable
annuity contracts in Separate Account Two, each a separate account registered
under the Investment Company Act of 1940, as amended (the "Separate Accounts").
However, Manufacturers Life of America has agreed to vote all shares of MSF in
proportion to the timely instructions received from holders of the contracts
issued by Manufacturers Life of America ("contractholders"). As a result, this
Prospectus/Proxy Statement is being furnished in connection with the
solicitation of voting instructions from such contractholders regarding the
proposal to shareholders
 
                                        1
<PAGE>   11
 
of MSF to approve the Reorganization. The ultimate parent of Manufacturers Life
of America is The Manufacturers Life Insurance Company ("Manulife"), a Canadian
mutual life insurance company whose principal address is 200 Bloor Street East,
Toronto, Ontario, Canada M4W 1E5.
 
   
     This Prospectus/Proxy Statement, which should be retained for future
reference, sets forth concisely the information about NASL and the NASL
Portfolios that a shareholder should know in considering the Reorganization. A
statement of additional information dated November   , 1996 (the "Statement of
Additional Information") containing additional information about NASL has been
filed with the Securities and Exchange Commission (the "Commission") and is
incorporated by reference into this Prospectus/Proxy Statement. A copy of the
Statement of Additional Information may be obtained without charge by writing to
NASL at the address noted above or by calling 1-800-827-8037. A copy of MSF's
current prospectus and statement of additional information may be obtained
without charge by writing to MSF at its address noted above or by calling
1-800-827-4546. If shareholders have any questions regarding the Reorganization,
please call 1-800-827-4546.

   EXCHANGE COMMISSION NOR HAS THE COMMISSION PASSED UPON THE ACCURACY OR
           ADEQUACY OF THIS PROSPECTUS/PROXY STATEMENT. ANY
              REPRESENTATION TO THE CONTRARY IS A CRIMINAL

                                    SUMMARY
 
     This summary is qualified by reference to the more complete information
contained in this Prospectus/Proxy Statement, the prospectus of MSF and the
Agreement and Plan of Reorganization attached to this Prospectus/Proxy Statement
as Exhibit A. The information concerning MSF contained or incorporated by
reference into this Prospectus/Proxy Statement has been furnished by MSF, and
the information concerning NASL contained or incorporated by reference into this
Prospectus/Proxy Statement has been furnished by NASL.
 
     Proposed Transaction.  The Board of Directors of MSF (the "MSF Board"),
including the Directors who are not "interested persons" of MSF (the
"Independent Directors"), has unanimously approved an Agreement and Plan of
Reorganization (the "Agreement") providing for the transfer of all of the assets
and liabilities of each Manulife Portfolio to a corresponding NASL Portfolio in
exchange for shares of such NASL Portfolio. The total value of all shares of
each NASL Portfolio issued in the Reorganization shall equal the total value of
the net assets of the corresponding Manulife Portfolio being acquired by such
NASL Portfolio.
 
     As a result of the Reorganization, each holder of shares of each Manulife
Portfolio specified in the table below will become a holder of shares of the
NASL Portfolio listed opposite such Manulife Portfolio (each Manulife or NASL
Portfolio being referred to herein as the "corresponding" Manulife or NASL
Portfolio to the respective NASL or Manulife Portfolio listed opposite its
name). As a result, shareholders should carefully consider the information about
NASL and the NASL Portfolios presented in this Prospectus/Proxy Statement in
connection with voting on the Reorganization.

 * A newly organized portfolio of NASL.
** A newly organized portfolio of NASL created as a successor to the
   corresponding Manulife Portfolio in connection with the Reorganization.
 
     There are certain differences between the investment objectives, policies
and restrictions of the NASL Portfolios and the corresponding Manulife
Portfolios, as discussed below. See "Comparison of Investment Objectives and
Policies." The fee structure of the Manulife Portfolios will also change, as
discussed below. The existing purchase, redemption and dividend policies of the
Manulife Portfolios will remain substantially unchanged, except in the case of
the dividend policies of the Manulife Money-Market Fund, as discussed below.
 
     The consummation of the Reorganization is contingent on the satisfaction of
the conditions described below under "Information About the Reorganization."
Prior to or effective upon the consummation of the Reorganization, it is
anticipated that NASL will effect changes to the composition of NASL's Board of
Trustees (the "NASL Board") and obtain approval from NASL shareholders with
respect to a "manager of managers" proposal and changes in subadvisory
arrangements discussed under "Additional Information about NASL -- C. Management
of NASL" (collectively, the "Related Changes"). However, the failure of the NASL
shareholders to effect any or all of the Related Changes prior to the
Reorganization will not prevent the Reorganization from occurring. Information
contained herein with respect to NASL and the NASL Portfolios describes the
Related Changes where so indicated.
 
     If the Reorganization were to have been consummated as of June 30, 1996,
the approximate resulting aggregate net assets of the NASL Money Market Trust
would be $376,724,266; all other Manulife Portfolios would have merged into
newly created NASL Portfolios, with resulting net assets of approximately (1)
$26,477,252 in the case of the NASL International Stock Trust, (2) $191,192,652
in the case of the NASL Emerging Growth Trust, (3) $122,018,344 in the case of
the NASL Balanced Trust, (4) $76,032,098 in the case of the NASL Common Stock
Trust, (5) $19,626,583 in the case of the NASL Pacific Rim Emerging Markets
Trust, (6) $56,860,363 in the case of the NASL Real Estate Securities Trust, (7)
$41,329,264 in the case of the NASL Capital
 
                                        4
<PAGE>   14
 
Growth Bond Trust, and (8) $2,493,027 in the case of the NASL Equity Index
Trust.
 
     If the Reorganization were to have been consummated as of December 31,
1995, the approximate resulting aggregate net assets of the NASL Money Market
Trust would be $294,108,962; all other Manulife Portfolios would have merged
into newly created NASL Portfolios with resulting net assets of approximately
(1) $19,047,538 in the case of the NASL International Stock Trust, (2)
$162,426,467 in the case of the NASL Emerging Growth Trust, (3) $110,760,739 in
the case of the NASL Balanced Trust, (4) $60,995,928 in the case of the NASL
Common Stock Trust, (5) $13,057,099 in the case of the NASL Pacific Rim Emerging
Markets Trust, (6) $52,440,117 in the case of the NASL Real Estate Securities
Trust and (7) $42,693,786 in the case of the NASL Capital Growth Bond Trust.
 
     No gain or loss will be recognized by the NASL Portfolios or the Manulife
Portfolios or shareholders of the Manulife Portfolios for federal income tax
purposes as a result of the Reorganization. For further information about the
tax consequences of the Reorganization, see "Information about the
Reorganization -- Federal Income Tax Consequences."
 
     NASL Overview.  NASL is a series trust, which means that it has several
portfolios, each with a stated investment objective which it pursues through
separate investment policies. NASL is a no-load, open-end management investment
company organized as a Massachusetts business trust and registered with the
Commission under the Investment Company Act of 1940, as amended (the "1940
Act"), and each of the NASL Portfolios other than the NASL Emerging Growth Trust
is diversified for purposes of the 1940 Act.
 
     NASL currently serves as the underlying investment medium for sums invested
in variable annuity and variable life contracts issued by North American
Security Life Insurance Company ("Security Life"), First North American Life
Assurance Company ("FNAL") and Manufacturers Life of America. Seven portfolios
of NASL currently are made available for investment by Manufacturers Life of
America contractholders, but such portfolios do not include any of the NASL
Portfolios involved in the proposed Reorganization. NASL may in the future fund
annuity contracts issued by other insurance companies, among other things.
Currently, NASL has three shareholders, Security Life, FNAL and Manufacturers
Life of America. As is the case for MSF shares, NASL shares are not offered
directly to and may not be purchased directly by members of the public.
Consequently, as of the date of this Prospectus/Proxy Statement, the terms
"shareholder" and "shareholders" of NASL in this Prospectus/Proxy Statement
refer to Security Life, FNAL and Manufacturers Life of America.
 
     Under Massachusetts law, shareholders of NASL could, under certain
circumstances, be held personally liable for the obligations of NASL. However,
the Declaration of Trust disclaims shareholder liability for acts or obligations
of NASL,
 
                                        5
<PAGE>   15
 
and requires that notice of such disclaimer be given in each agreement,
obligation, or instrument entered into or executed by NASL or the Trustees.
Moreover, the Declaration of Trust provides for indemnification out of NASL
property for all losses and expenses of any shareholder held personally liable
for the obligations of NASL. Thus, the risk of a shareholder's incurring
financial loss on account of shareholder liability is considered by NASL to be
remote, since it is limited to circumstances in which the disclaimer is
inoperative, inadequate insurance existed (e.g., fidelity bonding and errors and
omissions insurance) and NASL itself is unable to meet its obligations. Under
Maryland law, MSF shareholders have no personal liability for MSF's acts or
obligations.
 
     Investment Management.  The following table illustrates the current
management arrangements for the Manulife Portfolios and the management
arrangements to be in effect for the corresponding NASL Portfolios upon
consummation of the Reorganization:

Money Market Trust pursuant to an agreement with NASL Financial and manages such
NASL Portfolio on a day-to-day basis, which arrangement is subject to NASL
shareholder ratification. If such shareholder ratification is not obtained, the

     Investment Policies and Restrictions.  In addition to the differences
between the investment objectives and approaches of certain of the Manulife
Portfolios and their corresponding NASL Portfolios, as set forth in the table
above, there are important differences between the investment policies of the
Manulife Money-Market Fund, Manulife International Fund, Manulife Emerging
Growth Equity Fund and Manulife Balanced Assets Fund and their corresponding
NASL Portfolios, as set forth in the tables below under the caption "Comparison
of Investment Objectives and Policies." There also are certain differences
between the investment restrictions applicable to the Manulife Portfolios and
the NASL Portfolios in pursuing their investment objectives that are listed
below under the caption "Comparison of Investment Objectives and Policies - J.
Additional Information on Investment Policies and Techniques and Risk Factors."
A complete list of the investment restrictions applicable to the NASL Portfolios
is set forth in the Statement of Additional Information under the caption
"Investment Restrictions."
 
     Additional Trust Portfolios.  In addition to the NASL Portfolios referred
to above, NASL currently offers the following sixteen additional portfolios:
 
                            NASL Small/Mid Cap Trust
                          NASL Blue Chip Growth Trust
                       NASL International Small Cap Trust
                            NASL Global Equity Trust
                               NASL Equity Trust
                               NASL Growth Trust
                                NASL Value Trust
                          NASL Growth and Income Trust
                   NASL International Growth and Income Trust
                           NASL Strategic Bond Trust
                       NASL Global Government Bond Trust
                       NASL Investment Quality Bond Trust
                     NASL U.S. Government Securities Trust
                     NASL Aggressive Asset Allocation Trust
                      NASL Moderate Asset Allocation Trust
                    NASL Conservative Asset Allocation Trust
 
     Commencing in January 1997, NASL expects to offer the following five
additional portfolios:
 
                            NASL Equity Income Trust
                             NASL High Yield Trust
                        NASL Science & Technology Trust
                        NASL Pilgrim Baxter Growth Trust
                          NASL Worldwide Growth Trust
 
                                        8
<PAGE>   18
 
     In addition, commencing in early 1997, NASL intends to offer the following
five additional portfolios (subject to the approval of the NASL Board):
 
                       NASL Conservative Lifestyle Trust
                         NASL Moderate Lifestyle Trust
                         NASL Balanced Lifestyle Trust
                          NASL Growth Lifestyle Trust
                        NASL Aggressive Lifestyle Trust
 
     Certain of the foregoing portfolios of NASL will not be available
immediately following the Reorganization as investment options under variable
contracts issued by Manufacturers Life of America. However, it is anticipated
that, within 1997, most of these funds will be made available as investment
options. See "Reasons for the Reorganization." NASL may add additional
portfolios from time to time in the future.
 
     Fees and Expenses.  The table which follows sets forth the ratios of
expenses to average net assets and expense examples for the Manulife Portfolios
for the fiscal year ended December 31, 1995, and the pro forma expense ratios
and expense examples for the shares of the corresponding NASL Portfolios as if
the Reorganization had occurred at the commencement of the fiscal year ended
December 31, 1995, based upon the fee arrangements that will be in place upon
the consummation of the Reorganization. As noted below, NASL Financial
voluntarily has agreed to limit the expense ratios of the NASL Common Stock
Trust, NASL Real Estate Securities Trust and NASL Capital Growth Bond Trust for
a period of one year following the consummation of the Reorganization to levels
no higher than the expense ratios of the corresponding Manulife Portfolios for
the year ended December 31, 1995.

    extraordinary expenses not incurred in the ordinary course of business)
    exceed .75% in the case of the NASL International Stock Trust and NASL

     THE "EXAMPLE" SET FORTH ABOVE SHOULD NOT BE CONSIDERED A REPRESENTATION OF
FUTURE EXPENSES OR ANNUAL RETURN; ACTUAL EXPENSES AND ANNUAL RETURN MAY BE
GREATER OR LESS THAN THOSE SHOWN. There can be no assurance that the foregoing
pro forma expense ratios would have been the actual expense ratios for the
corresponding NASL Portfolios had the Reorganization been consummated when
assumed above, or that the foregoing pro forma expense ratios reflect the actual
expense ratios that will be incurred by the corresponding NASL Portfolios
indicated above if the Reorganization is consummated. The purpose of this table
is to assist investors in understanding the expenses an investor in each of the
Manulife Portfolios and NASL Portfolios will bear. The variable contracts issued
by Manufacturers Life of America provide for charges not reflected in the above
table.
 
     Although the expense ratios of five of the NASL Portfolios are higher than
the expense ratios of the corresponding Manulife Portfolios, the MSF Board
believes that the higher expense ratios are consistent with current industry
standards. Furthermore, with respect to the NASL Emerging Growth Trust and NASL
Balanced Trust, the MSF Board believes that the higher expense ratios are
justified in light of the change in portfolio management of such portfolios.
With respect to the NASL Common Stock Trust, NASL Real Estate Securities Trust
and NASL Capital Growth Bond Trust, the MSF Board noted that NASL Financial
voluntarily has agreed to limit for a period of one year following the
consummation of the Reorganization the expense ratios of such NASL Portfolios to
levels no higher than the expense ratios of the corresponding Manulife
Portfolios for their most recently completed fiscal year, as noted above. The
expense ratios of the NASL Money Market Trust and NASL Equity Index Trust are
substantially the same as those of the corresponding Manulife Portfolios, while
the expense ratios of the NASL International Trust and NASL Pacific Rim Emerging
Markets Trust are lower than those of the corresponding Manulife Portfolios.

     MAC currently is providing advisory services and bearing most of the
expenses of the Manulife Portfolios pursuant to an advisory agreement which it
can terminate without penalty on 60 days' notice. MAC recently has expressed to
the MSF Board its desire to eliminate its direct subsidization of the Manulife
Portfolios' expenses. Moreover, Manulife has indicated that new variable annuity
and variable life products it makes available in the future are likely to use
NASL as the underlying investment medium rather than MSF, thereby limiting MSF's
opportunities for growth and causing its potential stagnation or decline, and
MAC has indicated that this could make it more difficult for it to continue to
subsidize the expenses of the Manulife Portfolios as it has done in the past. If
shareholders do not approve the Reorganization and MAC terminates its current
advisory agreement, the MSF Board would be forced to consider alternative
advisory arrangements, and the MSF Board believes that the existing expense
ratios of most of the Manulife Portfolios would be difficult to maintain under
current market conditions in light of the higher total fees and expenses borne
by many mutual funds with similar investment objectives. In light of these
considerations, the MSF Board believes that the overall opportunities for MSF
shareholders presented by the proposed Reorganization outweigh the increases in
fees.
 
     For the foregoing reasons and those set forth below under "Reasons for the
Reorganization," the MSF Board, including all of the Independent Directors, has
unanimously concluded that the Reorganization is in the best interests of each
Manulife Portfolio, as well as its shareholders and the contractholders whose
contract values are invested in shares thereof, and that the interests of
existing shareholders and contractholders will not be diluted as a result of the
Reorganization. The MSF Board has unanimously recommended to shareholders
approval of the Reorganization.
 
     For more complete information regarding the historical and projected
expenses of the NASL Portfolios, see "Additional Information about NASL - A.
Expenses."
 
     Purchase and Redemption.  Like MSF, shares of NASL are offered
continuously, without sales charge, at prices equal to the respective net asset
values of the portfolio being purchased. Both MSF and NASL sell their shares
directly without the use of any underwriter. Shares of NASL are sold and
redeemed at their net asset value next computed after a purchase payment or
redemption request is received by the shareholder from the contract owner or
after any other purchase or redemption order is received by NASL. Depending upon
the net asset values at that time, the amount paid upon redemption may be more
or less than the cost of the shares when they were purchased. Payment for shares
redeemed will be made as soon as possible, but in any event within seven days
after receipt of a request for redemption. Unlike the Manulife Money-Market
Fund, the NASL Money Market Trust intends to maintain to the extent practicable
a constant per share net asset value of $10.00, although there is no assurance
that it will be able to do so.
 
     Dividends and Distributions.  Like MSF, NASL intends to declare as
dividends substantially all of the net investment income, if any, of each of the
NASL
 
                                       13
<PAGE>   23
 
Portfolios. For dividend purposes, net investment income of each NASL Portfolio,
except the NASL Money Market Trust, will consist of all payments of dividends
(other than stock dividends) or interest received by such NASL Portfolio less
the estimated expenses of such NASL Portfolio (including fees payable to NASL
Financial). For the NASL Money Market Trust net investment income will consist
of the interest income earned on investments, plus or minus amortized purchase
discount or premium, plus or minus realized gains and losses, less estimated
expenses. Dividends from the net investment income and the net realized
short-term and long-term capital gains, if any, for each portfolio, except the
NASL Money Market Trust, will be declared not less frequently than annually and
reinvested in additional full and fractional shares of that NASL Portfolio or
paid in cash. Dividends from net investment income and net realized short-term
and long-term capital gains, if any, for the NASL Money Market Trust will be
declared and reinvested, or paid in cash, daily. In contrast, the Manulife
Money-Market Fund declares and pays dividends annually, and none of the Manulife
Portfolios offer a cash dividend option to shareholders.
 
     Risk Factors.  The risks associated with an investment in a NASL Portfolio,
in general, are those typically associated with investing in a managed portfolio
of the specific types of instruments in which that NASL Portfolio invests. All
of the NASL Portfolios may invest to varying degrees in the securities of
foreign issuers and certain of the portfolios may invest in derivatives, which
entail certain additional risks. Further information relating to these and other
risks associated with an investment in the NASL Portfolios is set forth below
under "Comparison of Investment Objectives and Policies."
 
     Manulife Money-Market Fund and NASL Money Market Trust.  Risks of
investment in these portfolios relate primarily to risks of investing in
obligations of U.S. banks and their foreign branches and investments in
dollar-denominated securities of Canadian issuers. Investment in the NASL Money
Market Trust includes the additional risks of investing in obligations of
foreign banks, dollar-denominated securities of foreign issuers other than
Canadian issuers and commercial paper rated in the second highest rating
category.
 
     Manulife International Fund and NASL International Stock Trust.  Risks of
investment in these portfolios relate primarily to fluctuations in stock prices
and risks associated with foreign investing. Investment in the NASL
International Stock Trust currently also includes the additional risks of
investing in certain emerging markets and risks associated with investments in
derivatives for purposes other than hedging portfolio risks.
 
     Manulife Emerging Growth Equity Fund and NASL Emerging Growth Trust. Risks
of investment in these portfolios relate primarily to fluctuations in stock
prices and risks associated with investments in the securities of smaller, less
seasoned companies (which generally exhibit greater volatility and are otherwise
subject to greater risks than the securities of larger, more established
companies). Investment in the NASL Emerging Growth Trust includes the additional
risks of investing in a
 
                                       14
<PAGE>   24
 
wider range of foreign securities. The NASL Emerging Growth Trust also is a non-
diversified portfolio, unlike the Manulife Emerging Growth Equity Fund, and
therefore bears risks associated with investing in a smaller number of
securities than a diversified portfolio.
 
     Manulife Balanced Assets Fund and NASL Balanced Trust.  Risks of investment
in these portfolios include fluctuations in stock prices as well as exposure to
interest rate and credit risks with respect to fixed-income securities
(including mortgage-related securities). Investment in the NASL Balanced Trust
also includes the additional risks associated with its ability to invest up to
5% of its assets in junk bonds, including the greater risk of default by the
issuers of such bonds, and its ability to invest in a wider range of securities
of foreign issuers.
 
     Manulife Common Stock Fund and NASL Common Stock Trust.  Risks of
investment in these portfolios relate primarily to fluctuations in stock prices.
 
     Manulife Pacific Rim Emerging Markets Fund and NASL Pacific Rim Emerging
Markets Trust.  Risks of investment in these portfolios relate primarily to
fluctuations in stock prices and risks associated with foreign investing.
 
     Manulife Real Estate Securities Fund and NASL Real Estate Securities Trust.
Risks of investment in these portfolios relate primarily to their ability to
concentrate their investments in the real estate industry, including risks of
fluctuations in real estate related stock prices and exposure to interest rate
and credit risks with respect to real estate related fixed-income securities.
Investment in the NASL Real Estate Securities Trust includes the additional
risks of investing in mortgage-related securities including the risk of early
principal repayments in a declining interest rate environment.
 
     Manulife Capital Growth Bond Fund and NASL Capital Growth Bond Trust. Risks
of investment in these portfolios relate primarily to exposure to interest rate
and credit risks with respect to fixed-income securities. Investment in the NASL
Capital Growth Bond Trust includes the additional risks of investing in
mortgage-related securities.
 
     Manulife Equity Index Fund and NASL Equity Index Trust.  Risks of
investment in these portfolios relate to fluctuations in the values of the
common stocks comprising the Standard & Poor's 500 Composite Stock Price Index.
 
                         REASONS FOR THE REORGANIZATION
 
     The MSF Board and the NASL Board have approved the Reorganization as a
means by which MSF and NASL may be combined into a single fund family following
the merger earlier this year of the companies that control each fund's
investment adviser. NASL Financial, the investment adviser to NASL, is a wholly
owned subsidiary of Security Life, the ultimate parent of which is Manulife.
Prior to January 1, 1996, Security Life was a wholly owned subsidiary of North
American Life Assurance Company ("NAL"), a Canadian mutual life insurance
company.
 
                                       15
<PAGE>   25
 
On January 1, 1996 NAL and Manulife merged with the combined company retaining
the name Manulife. MAC, the investment manager of MSF, also is an indirect
wholly owned subsidiary of Manulife.
 
     In determining whether to recommend approval of the Reorganization to
shareholders, the MSF Board (including the Independent Directors, with the
advice and assistance of independent legal counsel) made an inquiry into a
number of matters and considered the following factors, among others: (1) the
advantages to shareholders of investing in a series fund with a modern strategy
of offering investment opportunities that address investor needs at multiple
risk/reward levels; (2) the capability of NASL Financial to offer flexibility
and the potential for greater and more diverse investment opportunities; (3) the
multiple manager approach by which NASL Financial monitors and evaluates
subadviser performance, investment compliance and capabilities with the goal of
maintaining high quality and an appropriate balance of investment alternatives;
(4) expense ratios and available information regarding the fees and expenses of
each Manulife Portfolio and each corresponding NASL Portfolio (historical and
pro forma), as well as of similar funds; (5) the fact that NASL Financial has
agreed to limit the total expenses of certain of the NASL Portfolios for one
year following the Reorganization to a level no higher than the existing levels
of total expenses of the corresponding Manulife Portfolios; (6) the
sophistication and specialization of the new subadvisers for certain of the NASL
Portfolios; (7) the compatibility of the investment objectives, policies,
restrictions and portfolios (where applicable) of each Manulife Portfolio and
each corresponding NASL Portfolio; (8) the advantages to each Manulife Portfolio
of investing in potentially larger asset pools with greater diversification; (9)
the historical performance of the Manulife Portfolios and the NASL Money Market
Trust, as well as of each portfolio's respective investment adviser and
subadviser where relevant; (10) portfolio transaction policies of the Manulife
Portfolios and the NASL Portfolios; (11) the terms and conditions of the
Reorganization and whether the Reorganization would result in dilution of
shareholder or contractholder interests; (12) any direct and indirect costs
incurred by each Manulife Portfolio and each corresponding NASL Portfolio as a
result of the Reorganization; (13) tax consequences of the Reorganization; and
(14) possible alternatives to the Reorganization.
 
     In reaching the decision to recommend approval of the Reorganization, the
MSF Board concluded that the participation of each Manulife Portfolio in the
Reorganization is in the best interests of such Manulife Portfolio, as well as
its shareholders and the contractholders whose contract values are invested in
shares thereof, and that the interests of existing shareholders and
contractholders will not be diluted as a result of such participation. Their
conclusion was based on a number of factors, including the following:
 
     1. The Reorganization will enable contractholders to take advantage of an
        investment management approach known as managing to the "Efficient
        Frontier" in which investors allocate their assets among a broad mix of
 
                                       16
<PAGE>   26
 
        investment choices consistent with their risk tolerance levels with the
        goal of maximizing their risk adjusted investment return. In connection
        with this approach, it is anticipated that, within 1997, most of the
        other funds in the NASL family will be made available as investment
        options in most of the variable contracts issued by Manufacturers Life
        of America prior to the Reorganization, providing contractholders with
        direct access to a wide range of investment alternatives. NASL intends,
        in early 1997, to add several asset allocation portfolios to its fund
        family in connection with the expansion of the "Efficient Frontier"
        investment management approach.
 
     2. The Reorganization also will allow shareholders to receive the
        investment advisory services of NASL Financial and its multiple manager
        approach to portfolio management. NASL Financial selects, contracts with
        and compensates subadvisers to manage the NASL Portfolios on a
        day-to-day basis, monitors the compliance of such subadvisers with the
        investment objectives and policies of each NASL Portfolio, and reviews
        the performance of such subadvisers and reports periodically on such
        performance to the NASL Board. This multiple manager approach is
        intended to help maintain high portfolio management quality and an
        appropriate balance of investment alternatives. This includes the
        introduction of high-profile money managers such as Founders,
        Price-Fleming and Warburg Pincus. Even those Manulife Portfolios that
        will continue to receive the day-to-day management of MAC will have the
        benefits of NASL Financial's oversight capabilities in the context of a
        broader overall approach to investing. NASL Financial currently is
        investment adviser to 30 mutual fund portfolios, which invest in a broad
        array of assets and include domestic as well as international funds.
 
     3. Although, as discussed above, the expense ratios of five of the NASL
        Portfolios are higher than the expense ratios of the corresponding
        Manulife Portfolios, the MSF Board believes that the higher expense
        ratios are consistent with current industry standards. Furthermore, with
        respect to the NASL Emerging Growth Trust and NASL Balanced Trust, the
        MSF Board believes that the higher expense ratios are justified in light
        of the change in portfolio management of such portfolios, while, with
        respect to the NASL Common Stock Trust, NASL Real Estate Securities
        Trust and NASL Capital Growth Bond Trust, the MSF Board noted that NASL
        Financial voluntarily has agreed to limit for a period of one year
        following the consummation of the Reorganization the expense ratios of
        such NASL Portfolios to levels no higher than the expense ratios of the
        corresponding Manulife Portfolios for their most recently completed
        fiscal year. The expense ratios of the NASL Money Market Trust and NASL
        Equity Index Trust are substantially the same as those of the
        corresponding Manulife Portfolios, while the expense ratios of the NASL
        International Trust and NASL Pacific Rim Emerging Markets Trust are
        lower than those of the corresponding Manulife Portfolios.
 
                                       17
<PAGE>   27
 
     4. MAC currently is providing advisory services and bearing most of the
        expenses of the Manulife Portfolios pursuant to an advisory agreement
        which it can terminate without penalty on 60 days' notice. MAC recently
        has expressed to the MSF Board its desire to eliminate its direct
        subsidization of the Manulife Portfolios' expenses. Moreover, Manulife
        has indicated that new variable annuity and variable life products it
        makes available in the future are likely to use NASL as the underlying
        investment medium rather than MSF, thereby limiting MSF's opportunities
        for growth and causing its potential stagnation or decline, and MAC has
        indicated that this could make it more difficult for it to continue to
        subsidize the expenses of the Manulife Portfolios as it has done in the
        past. If shareholders do not approve the Reorganization and MAC
        terminates its current advisory agreement, the MSF Board would be forced
        to consider alternative advisory arrangements, and the MSF Board
        believes that the existing expense ratios of most of the Manulife
        Portfolios would be difficult to maintain under current market
        conditions in light of the higher total fees and expenses borne by many
        mutual funds with similar investment objectives.
 
   
     5. The Reorganization will permit shareholders of the Manulife Money-Market
        Fund to pursue substantially the same investment goals in a larger fund
        immediately following consummation of the Reorganization. While the
        other NASL Portfolios have been newly organized, and therefore
        immediately following the Reorganization will not be larger than the
        corresponding Manulife Portfolios, all of the NASL Portfolios should
        benefit from being part of a single combined fund family that is used as
        the underlying investment medium for variable contracts issued by
        Manufacturers Life of America, Security Life and FNAL. It is anticipated
        that, as a result of the Reorganization, the combined Manulife and NASL
        Portfolios will experience more rapid asset growth in the future than
        would have been the case for the Manulife Portfolios standing alone.
        Such larger funds should enhance the ability of portfolio managers to
        effect portfolio transactions on more favorable terms and give portfolio
        managers greater investment flexibility and the ability to select a
        larger number of portfolio securities, with the attendant benefits of
        increased diversification.
 
     The NASL Board determined to approve the Reorganization on behalf of NASL
because the Reorganization would increase NASL's total assets, as well as
provide initial assets for the new NASL Portfolios to be offered upon
consummation of the Reorganization.
    
 
                      INFORMATION ABOUT THE REORGANIZATION
 
     Agreement and Plan of Reorganization.  The following summary of the
Agreement is qualified in its entirety by reference to the form of the Agreement
attached to this Prospectus/Proxy Statement as Exhibit A. The Agreement, to
which MSF and NASL are parties, provides that each NASL Portfolio will acquire
 
                                       18
<PAGE>   28
 
all of the assets and liabilities of the corresponding Manulife Portfolio in
exchange for shares of such NASL Portfolio. Subject to the satisfaction of the
conditions described below, such acquisitions shall take place on December 31,
1996 or such later date as may be agreed upon by the parties (the "Closing
Date"). The net asset value per share for each NASL Portfolio will be determined
by dividing each NASL Portfolio's assets, less liabilities, by the total number
of its outstanding shares. NASL Portfolio assets will be valued in accordance
with the valuation practices of the NASL Portfolios, which are described below
under "Additional Information About NASL - F. Other Information Concerning
Shares of NASL." Manulife Portfolio assets will be valued in accordance with the
valuation practices of the Manulife Portfolios.
 
     The number of full and fractional shares of a NASL Portfolio received by a
shareholder of the corresponding Manulife Portfolio will be equal in value to
the value of that shareholder's shares of the corresponding Manulife Portfolio
as of the close of regularly scheduled trading on the New York Stock Exchange on
the closing date of the Reorganization. As promptly as practicable after the
Closing Date, each Manulife Portfolio will liquidate and distribute pro rata to
its shareholders of record as of the close of regularly scheduled trading on the
New York Stock Exchange on the Closing Date the shares of the corresponding NASL
Portfolio received by that Manulife Portfolio in the Reorganization. Such
liquidation and distribution will be accomplished by the establishment of
accounts on the share records of the NASL Portfolios in the names of the
shareholders of the corresponding Manulife Portfolio, each account representing
the respective pro rata number of shares of such NASL Portfolio due the
shareholder. After such distribution and the winding up of its affairs, the
Manulife Portfolios will be terminated and MSF will be dissolved and
deregistered as an investment company under the 1940 Act and dissolved under
state law.
 
     The NASL Board and the MSF Board have each determined, with respect to
their respective portfolios that are parties to the Reorganization, that the
interests of shareholders and of contractholders whose contract values are
invested in shares of such portfolios will not be diluted as a result of the
Reorganization and that participation in the Reorganization is in the best
interests of such portfolios and such shareholders and contractholders.
 
     Certain of the existing investment limitations of the Manulife Portfolios
that require shareholder approval for amendment prohibit each Manulife Portfolio
from engaging in activities such as investing more than a stated percentage of
its assets in an issuer's securities. By approving the Agreement, the
shareholders of the Manulife Portfolios will be deemed to have agreed to waive
any such limitations solely insofar as they might be deemed to apply to the
Reorganization.
 
     The consummation of the Reorganization is subject to the conditions set
forth in the Agreement, including that the majority of the shareholders of each
Manulife Portfolio approve the Reorganization and that the Commission grant
exemptive relief from certain provisions of the 1940 Act that otherwise would
preclude
 
                                       19
<PAGE>   29
 
consummation of the Reorganization. On September 19, 1996 MSF and NASL filed an
Application with the Commission requesting exemption from certain provisions of
the 1940 Act as they relate to the proposed Reorganization. Manulife,
Manufacturers Life of America, Security Life and FNAL also are parties to the
Application. Copies of the Application may be obtained from the Commission in
the manner explained below. See "Additional Information About NASL - H.
Additional Information." In addition, the proposal to approve the Agreement will
not be submitted to shareholders of the Manulife Portfolios, and the Special
Meeting of Shareholders therefore will not be held, until such time as the
Commission has granted the exemptive relief referred to in the preceding
sentence. There can be no assurance that the Commission will grant such
exemptive relief or that it will be granted in time for the Special Meeting of
Shareholders to be held on December 20, 1996 as scheduled.
 
     The Agreement may be terminated and the Reorganization abandoned at any
time prior to the Closing Date, before or after approval by the shareholders of
the Manulife Portfolios, by either MSF or NASL if (i) any condition or covenant
set forth in the Agreement has not been fulfilled or waived by the party
entitled to its benefits, (ii) there has been a material breach by the other
party or (iii) the NASL Board or the MSF Board, as the case may be, determines
that proceeding with the Reorganization is not in the best interests of NASL or
MSF, respectively, or their respective shareholders or contractholders. The
Agreement provides that either party may waive compliance with any of the
covenants or conditions made therein for its benefit, except for certain
conditions regarding the receipt of regulatory approvals.
 
     The expenses of the Reorganization (other than registration fees payable
for the registration of shares of the NASL Portfolios in connection with the
Reorganization, which will be payable by such NASL Portfolios), including the
cost of a proxy soliciting agent that has been retained (see "Voting
Information"), will be borne by NASL Financial or its affiliates (other than MSF
or NASL).
 
     Approval of the Agreement will require the affirmative vote of the holders
of at least a majority of the outstanding shares of each Manulife Portfolio
entitled to vote on the matter. If the Reorganization is not approved by the
shareholders of each Manulife Portfolio or is not consummated for any other
reason, the MSF Board will consider other possible courses of action. Approval
of the Agreement by the shareholders of each Manulife Portfolio will also
constitute approval of MSF's dissolution and deregistration as an investment
company under the 1940 Act and termination under state law following
consummation of the Reorganization. See "Voting Information." THE MSF BOARD HAS
UNANIMOUSLY RECOMMENDED APPROVAL OF THE AGREEMENT.
 
     Shareholders of each Manulife Portfolio will receive shares of the
corresponding NASL Portfolio in accordance with the procedures provided for in
the Agreement as described above. Each such share will be fully paid and non-
assessable when issued (except as noted under "Comparative Information on
 
                                       20
<PAGE>   30
 
Shareholder Rights -- Shareholder Liability") and transferable without
restrictions and will have no preemptive or conversion rights.
 
     Federal Income Tax Consequences.  As a condition to the consummation of the
Reorganization, MSF and NASL will each receive an opinion from Simpson Thacher &
Bartlett (a partnership which includes professional corporations) to the effect
that, based on the facts and assumptions stated therein, for federal income tax
purposes: (1) the Reorganization will constitute a reorganization within the
meaning of Section 368(a)(1) of the Internal Revenue Code of 1986, as amended
(the "Code") with respect to each Manulife Portfolio and its corresponding NASL
Portfolio; (2) no gain or loss will be recognized by any of the Manulife
Portfolios or the corresponding NASL Portfolios upon the transfer of all of the
assets and liabilities, if any, of each Manulife Portfolio to its corresponding
NASL Portfolio solely in exchange for corresponding NASL Portfolio shares or
upon the distribution of the shares of the corresponding NASL Portfolios to the
shareholders of the Manulife Portfolios solely in exchange for all of their
shares of the Manulife Portfolios; (3) no gain or loss will be recognized by
shareholders of any of the Manulife Portfolios upon the exchange of such
Manulife Portfolio's shares solely for shares of its corresponding NASL
Portfolio; (4) the holding period and tax basis of the corresponding NASL
Portfolio shares received by each shareholder of each Manulife Portfolio
pursuant to the Reorganization will be the same as the holding period (provided
the shares of the Manulife Portfolios were held as a capital asset on the date
of the Reorganization) and tax basis of the shares of the Manulife Portfolio
held by the shareholder immediately prior to the Reorganization; and (5) the
holding period and tax basis of the assets of each of the Manulife Portfolios
acquired by its corresponding NASL Portfolio will be the same as the holding
period and tax basis of those assets to each of the Manulife Portfolios
immediately prior to the Reorganization. The payment by NASL Financial or its
affiliates of certain expenses of MSF and NASL which are directly related to the
Reorganization will not affect such opinion. However, no opinion will be given
as to any other federal income tax consequences of the payment of such expenses.
 
     Capitalization. The following tables show the capitalization of each
Manulife Portfolio and the corresponding NASL Portfolio as of June 30, 1996 and
December 31, 1995, and on a pro forma combined basis as of those dates for the
Reorganization giving effect to the proposed acquisition of assets at net asset
value.

(1) The indicated NASL Portfolios have been newly organized; no shares of such
    portfolios are outstanding at June 30, 1996 or December 31, 1995.

    accordingly, no shares of such portfolio are outstanding at December 31,

                               VOTING INFORMATION
 
     Proxies from the shareholders of each Manulife Portfolio are being
solicited by the MSF Board for the Special Meeting of Shareholders to be held on
Decem-
 
                                       24
<PAGE>   34
 
ber 20, 1996 at the offices of NASL, 116 Huntington Avenue, Boston,
Massachusetts 02116, at 10:00 a.m., Eastern Standard Time, or at such later time
as necessary by adjournment. All valid proxies will be voted in accordance with
the specification thereon, or in the absence of specification, for approval of
the Agreement. Approval of the Agreement will require the affirmative vote of
the holders of at least a majority of the outstanding shares of each portfolio
of MSF entitled to vote thereon. Approval of the Agreement by the shareholders
of each Manulife Portfolio will also constitute approval of MSF's dissolution
and deregistration as an investment company under the 1940 Act and termination
under state law following consummation of the Reorganization.
 
   
     Abstentions do not count as votes cast with respect to the Reorganization
proposal. Under the 1940 Act, the affirmative vote necessary to approve a matter
under consideration may be determined with reference to a percentage of votes
present at the Meeting, which would have the effect of treating abstentions as
if they were votes against the Reorganization proposal.
    
 
     The cost of the preparation and distribution of these proxy materials will
be borne by NASL Financial or its affiliates (other than MSF or NASL). In
addition to the solicitation of proxies by the use of the mails, proxies may be
solicited by officers and employees of Manulife, or of its agents or affiliates,
personally or by telephone. Brokerage houses, banks and other fiduciaries may be
requested to forward soliciting materials to their principals and to obtain
authorization for the execution of proxies. For those services, they will be
reimbursed by NASL Financial or its affiliates (other than MSF or NASL) for
their out-of-pocket expenses.
 
     Under the Agreement, shareholders of each Manulife Portfolio will receive
shares of the corresponding NASL Portfolio, as described above, with an
aggregate net asset value equal to the value of the shareholder's investment in
each Manulife Portfolio at the effective time of the transaction. This method of
valuation is also consistent with interpretations of Rule 22c-1 under the 1940
Act by the Commission's Division of Investment Management. Any shareholder of a
Manulife Portfolio may redeem shares at the then-current net asset value prior
to the Closing Date.
 
     Shareholders of the Manulife Portfolios of record at the close of business
on October 23, 1996 will be entitled to vote at the Meeting or any adjournment
of the Meeting. The holders of a majority of the shares outstanding of each such
Manulife Portfolio at the close of business on that date present in person or
represented by proxy will constitute a quorum for the Meeting; however, as noted
above, the affirmative vote of at least a majority of the shares outstanding of
each such Manulife Portfolio at the close of business on that date is required
to approve the Reorganization. Shareholders are entitled to one vote for each
share held and fractional votes for fractional shares held. Shares of the
Manulife Portfolios are sold only to Manufacturers Life of America and to the
Separate Accounts. Although Manufacturers Life of America owns all shares of the
Manulife Portfolios, shares are attributed to, and will be voted in accordance
with instructions received from, the contractholders of variable life and
variable annuity contracts issued by
 
                                       25
<PAGE>   35
 
Manufacturers Life of America. Accordingly, Manufacturers Life of America will
vote shares in accordance with instructions received from contractholders.
Contractholders have voting rights with respect to each of the Manulife
Portfolios in which they have an interest. Manulife Portfolio shares as to which
no voting instructions are received, including shares not attributable to
contractholders, will be voted by Manufacturers Life of America in the same
proportion as those for which voting instructions are received from
contractholders.
 
   
     As of October 23, 1996, as shown on the books of MSF, there were issued and
outstanding 3,967,181.047 shares of Manulife Money-Market Fund, 2,632,966.869
shares of Manulife International Fund, 8,796,098.219 shares of Manulife Emerging
Growth Equity Fund, 7,331,852.286 shares of Manulife Balanced Assets Fund,
4,368,604.986 shares of Manulife Common Stock Fund, 1,987,684.820 shares of
Manulife Pacific Rim Emerging Markets Fund, 3,844,065.002 shares of Manulife
Real Estate Securities Fund, 3,874,019.607 shares of Manulife Capital Growth
Fund and 612,192.564 shares of Manulife Equity Index Fund. At that date, all of
such MSF shares were held in sub-accounts of the Separate Accounts and will be
voted by Manufacturers Life of America.
 
     As of October 23, 1996, Manufacturers Life of America owned 39.10%, 35.82%
and 4.79% of the Manulife International Fund, Manulife Pacific Rim Emerging
Markets Fund and Manulife Equity Index Fund, respectively. As of October 23,
1996, 7.83% of the Manulife Money-Market Fund's shares were attributable to a
contract owned by Ali R. Ghahramani, 7223 Ayrshire Lane, Boca Raton, Florida,
5.01% of the Manulife Money-Market Fund's shares were attributable to a contract
owned by Broad 1984 Security Trust, 1999 Avenue of the Stars, Los Angeles,
California, 36.03% of the Manulife Equity Index Fund's shares were attributable
to a contract owned by the James F. and Lois R. Ackerman Irrevocable Trust dated
November 9, 1987, 8910 Purdue Road, Indianapolis, Indiana, 6.22% of the Manulife
Equity Index Fund's shares were attributable to a contract owned by the Wilder
Irrevocable Trust of 1996 dated April 2, 1996, 2108-137th Place, S.E., Bellevue,
Washington and 12.20% of the Manulife Capital Growth Bond Fund's shares were
attributable to a contract owned by IFDA Services, Inc., 215 S. Grand Avenue
West, Springfield, Illinois. Upon the consummation of the Reorganization, except
in the case of persons to whom shares of the Manulife Money-Market Fund were
attributable at the record date, each of the foregoing persons would have the
same percentage of attributable shares of the corresponding NASL Portfolio. In
the case of the Manulife Money-Market Fund, based on shares outstanding at the
record date, Mr. Ghahramani would have attributable to his contract 0.89% of the
shares of the NASL Money Market Trust and Broad 1984 Security Trust would have
attributable to its contract 0.57% of the shares of the NASL Money Market Trust.
 
     The votes of the shareholders of the corresponding NASL Portfolios are not
being solicited to approve the Reorganization, since their approval or consent
is not required with respect to the Reorganization. Their votes are being
solicited, however, in connection with the approval of the Related Changes.

     The Agreement was approved for MSF by unanimous vote of the MSF Board and
for NASL by unanimous vote of the NASL Board, including in each case all of the
Directors and Trustees, respectively, then serving who were not interested
persons of MSF or NASL (other than in their capacity as Directors or Trustees of
MSF or NASL, as the case may be).
 
                COMPARISON OF INVESTMENT OBJECTIVES AND POLICIES
 
     The investment objective and policies of each of the NASL Portfolios are
set forth below, together with a discussion of the primary differences, if any,
from those of the respective corresponding Manulife Portfolios.
 
     Each NASL 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 NASL Portfolio is subject.
 
     The investment objectives of each NASL Portfolio represent fundamental
policies of each such NASL Portfolio and may not be changed without the approval
of the holders of a majority of the outstanding shares of the NASL Portfolio.
Except for certain investment restrictions, the policies by which a NASL
Portfolio seeks to achieve its investment objectives may be changed by the NASL
Board without the approval of NASL shareholders.
 
     The following is a description of the investment objectives and policies of
each NASL Portfolio. More complete descriptions of the money market instruments
in which the NASL Portfolios may invest and of the options, futures, currency
and other derivative transactions that certain NASL Portfolios may engage in are
set forth in the Statement of Additional Information. A more complete
description of the debt security ratings used by the NASL Portfolios assigned by
Moody's Investors Service, Inc. ("Moody's") or Standard and Poor's Corporation
("S&P") is included in the Appendix to this Prospectus/Proxy Statement.
 
     Because the value of securities and the income derived therefrom may
fluctuate according to the earnings of the issuers and changes in economic and
market conditions, there can be no assurance that the investment objective of
any of the NASL Portfolios will be achieved.
 
A. NASL MONEY MARKET TRUST
 
     The investment objective of the NASL Money Market Trust is to obtain
maximum current income consistent with preservation of principal and liquidity.
Since October 1, 1996, MAC has managed the NASL Money Market Trust 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 and interest by the
     United States Government, or any agency or authority controlled or
     supervised by and
 
                                       27
<PAGE>   37
 
     acting as an instrumentality of the U.S. Government pursuant to authority
     granted by Congress (hereinafter "U.S. Government securities"), or
     obligations of foreign governments including those issued or guaranteed as
     to principal or interest by the Government of Canada, the government of any
     province of Canada, or any Canadian or provincial Crown agency (any foreign
     obligation acquired by NASL will be payable in U.S. dollars);
 
     (2) certificates of deposit, bank notes, time deposits, Eurodollars, Yankee
     obligations 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 Saving 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 MAC acting pursuant
     to guidelines established by the NASL Board, has determined to be of
     minimal credit risk and comparable quality;
 
     (4) corporate obligations maturing in 397 days or less which at the date of
     investment are rated within the two highest rating categories by any NRSRO

B. NASL INTERNATIONAL STOCK TRUST
 
     The investment objective of the NASL International Stock Trust is long-term
growth of capital. Rowe Price-Fleming International, Inc. ("Price-Fleming")
manages the NASL International Stock Trust and seeks to attain this objective by
investing primarily in common stocks of established, non-U.S. companies. The
NASL International Stock Trust expects to invest substantially all of its assets
outside the U.S. and to diversify broadly among countries throughout the
world -- developed, newly industrialized, and emerging. The NASL International
Stock Trust will invest in at least three countries outside the United States.
 
     The NASL International Stock Trust expects to invest substantially all of
its assets in common stocks. However, the NASL International Stock Trust may
also invest in a variety of other equity-related securities, such as preferred
stocks, warrants and convertible securities, as well as corporate and
governmental debt securities, when considered consistent with its investment
objectives and program. Under normal market conditions, the NASL International
Stock Trust's investment in securities other than common stocks is limited to no
more than 35% of total assets. However, for temporary defensive purposes, the
NASL International Stock Trust may invest all or a significant portion of its
assets in U.S. Government and corporate debt obligations. The NASL International
Stock Trust will not purchase any debt security which at the time of purchase is
rated below investment grade. This would not prevent the NASL International
Stock Trust from retaining a security downgraded to below investment grade after
purchase.
 
     The NASL International Stock Trust will hold a certain portion of its
assets in U.S. and foreign dollar-denominated money market securities, including
repurchase agreements, in the two highest rating categories, maturing in one
year or less. For temporary, defensive purposes, the portfolio may invest
without limitation in such securities. This reserve position provides
flexibility in meeting redemptions, expenses, and the timing of new investments
and serves as a short-term defense during periods of unusual market volatility.
 
     Price-Fleming uses a "bottom-up" approach to stock selection based on
fundamental research. A company's prospects for achieving and sustaining above-
average, long-term earnings growth is generally the subadviser's primary focus.
However, valuation factors, such as price/earnings, price/cash flow, and
price/book value are also important considerations. In conjunction with
identifying potential stocks for investment, external factors are also reviewed.
For example, a country's or region's political, economic, and financial status
help shape the outlook for individual stocks and also affect decisions regarding
the prudent level of overall exposure to particular areas.
 
     It is the present intention of Price-Fleming to invest in companies based
in (or governments of or within) the Far East (for example, Japan, Hong Kong,
Singapore, and Malaysia), Europe (for example, United Kingdom, Germany, Hungary,
Poland, Netherlands, France, Spain, and Switzerland), South Africa, Australia,
 
                                       30
<PAGE>   40
 
Canada, Latin America, and such other areas and countries as Price-Fleming may
determine from time to time.
 
     In determining the appropriate distribution of investments among various
countries and geographic regions, Price-Fleming ordinarily considers the
following factors: prospects for relative economic growth between foreign
countries; expected levels of inflation; government policies influencing
business conditions; the outlook for currency relationships; and the range of
individual investment opportunities available to international investors. In
analyzing companies for investment, Price-Fleming ordinarily looks for one or
more of the following characteristics: an above-average earnings growth per
share; high return on invested capital; a healthy balance sheet; sound financial
and accounting policies and overall financial strength; strong competitive
advantages; effective research and product development and marketing; efficient
service; pricing flexibility; strength of management; and general operating
characteristics which will enable the companies to compete successfully in their
market place.
 
     While current dividend income is not a prerequisite in the selection of
NASL International Stock Trust companies, the companies in which the NASL
International Stock Trust invests normally will have a record of paying
dividends, and will generally be expected to increase the amounts of such
dividends in future years as earnings increase. It is expected that the NASL
International Stock Trust's investments will ordinarily be traded on exchanges
located at least in the respective countries in which the various issuers of
such securities are principally based.
 
     The NASL International Stock Trust may purchase the securities of certain
foreign investment portfolios or trusts called passive foreign investment
companies. Such trusts have been the only or primary way to invest in certain
countries. In addition to bearing their proportionate share of the trust's
expenses (management fees and operating expenses), shareholders will also
indirectly bear similar expenses of such trusts. Capital gains on the sale of
such holdings are considered ordinary income regardless of how long the NASL
International Stock Trust held its investment. In addition, the NASL
International Stock Trust may be subject to corporate income tax and an interest
charge on certain dividends and capital gains earned from these investments,
regardless of whether such income and gains are distributed to shareholders. To
avoid such tax and interest, the NASL International Stock Trust intends to treat
these securities as sold on the last day of its fiscal year and recognize any
gains for tax purposes at that time; losses will not be recognized. Such gains
will be considered ordinary income, which the NASL International Stock Trust
will be required to distribute even though it has not sold the security.
 
     The NASL International Stock Trust may also engage in a variety of
investment management practices, such as buying and selling futures and options
and engaging in foreign currency exchange contracts. The NASL International
Stock Trust may invest up to 10% of its total assets in hybrid instruments,
which are a type of high-risk derivative which can combine the characteristics
of securities, futures and options. For example, the principal amount,
redemption or conversion
 
                                       31
<PAGE>   41
 
terms of a security could be related to the market price of some commodity,
currency or securities index. Such securities may bear interest or pay dividends
at below market (or even relatively nominal) rates. The Statement of Additional
Information contains a fuller description of such instruments and the risks
associated therewith.
 
     The NASL International Stock Trust will be subject to special risks as a
result of its ability to invest up to 100% of its total assets in foreign
securities. These include non-dollar-denominated securities traded outside of
the U.S. and dollar-denominated securities of foreign issuers traded in the U.S.
(such as ADRs). These risks are described under the caption "J. Additional
Information on Investment Policies and Techniques and Risk Factors -- Foreign
Securities." Moreover, substantial investments in foreign securities may have
adverse tax implications as described under "Additional Information About
NASL - E. Tax Matters."
 
  Use of Hedging and Other Strategic Transactions
 
     The NASL International Stock Trust is currently authorized to use all of
the various investment strategies referred to under "J. Additional Information
on Investment Policies and Techniques and Risk Factors -- Hedging and Other
Strategic Transactions." The Statement of Additional Information contains a
description of these strategies and of certain risks associated therewith.

C. NASL EMERGING GROWTH TRUST
 
     The investment objective of the NASL Emerging Growth Trust is maximum
capital appreciation. Warburg Pincus manages the NASL Emerging Growth Trust and
will pursue this objective by investing primarily in a portfolio of equity
securities of domestic companies.
 
     The NASL Emerging Growth Trust ordinarily will invest at least 65% of its
total assets in common stocks or warrants of emerging growth companies that
represent attractive opportunities for maximum capital appreciation. Emerging
growth companies are small- or medium-sized companies that have passed their
start-up phase and that show positive earnings and prospects of achieving
significant profit and gain in a relatively short period of time.
 
     The NASL Emerging Growth Trust is classified as a non-diversified
investment company under the 1940 Act, which means that portfolio is not limited
by the 1940 Act in the proportion of its assets that it may invest in the
obligations of a single issuer. As a non-diversified investment company, the
NASL Emerging Growth Trust may invest a greater proportion of its assets in the
obligations of a small number of issuers and, as a result, may be subject to
greater risk with respect to portfolio securities. To the extent that the NASL
Emerging Growth Trust assumes large positions in the securities of a small
number of issuers, its return may fluctuate to a greater extent than that of a
diversified company as a result of changes in the financial condition or in the
market's assessment of the issuers.
 
     Although under current market conditions the NASL Emerging Growth Trust
expects to invest in companies having stock market capitalizations of up to
approximately $500 million, the NASL Emerging Growth Trust may invest in
emerging growth companies without regard to their market capitalization.
Emerging growth companies generally stand to benefit from new products or
services, technological developments or changes in management and other factors
and include smaller companies experiencing unusual developments affecting their
market value. These "special situation companies" include companies that are
involved in the following: an acquisition or consolidation; a reorganization; a
recapitalization; a merger, liquidation, or distribution of cash, securities or
other assets; a tender or exchange offer; a breakup or workout of a holding
company; litigation which, if resolved favorably, would improve the value of the
company's stock; or a change in corporate control.
 
     The NASL Emerging Growth Trust may invest up to 20% of its total assets in
investment grade debt securities (other than money market obligations) and
preferred stocks that are not convertible into common stock for the purpose of
seeking capital appreciation. The interest income to be derived may be
considered as one factor in selecting debt securities for investment by Warburg
Pincus. Because the market value of debt obligations can be expected to vary
inversely to changes in prevailing interest rates, investing in debt obligations
may provide an opportunity for capital appreciation when interest rates are
expected to decline. The success of such
 
                                       34
<PAGE>   44
 
a strategy is dependent upon Warburg Pincus' ability to accurately forecast
changes in interest rates. The market value of debt obligations may also be
expected to vary depending upon, among other factors, the ability of the issuer
to repay principal and interest, any change in investment rating and general
economic conditions.
 
     A security will be deemed to be investment grade if it is rated within the
four highest grades by Moody's or S&P or, if unrated, is determined to be of
comparable quality by Warburg Pincus. Bonds rated in the fourth highest grade
may have speculative characteristics and changes in economic conditions or other
circumstances are more likely to lead to a weakened capacity to make principal
and interest payments than is the case with higher grade bonds. Subsequent to
its purchase by the NASL Emerging Growth Trust, an issue of securities may cease
to be rated or its rating may be reduced below the minimum required for purchase
by the NASL Emerging Growth Trust. Neither event will require sale of such
securities, although Warburg Pincus will consider such event in its
determination of whether the portfolio should continue to hold the securities.
 
     When Warburg Pincus believes that a defensive posture is warranted, the
NASL Emerging Growth Trust may invest temporarily without limit in investment
grade debt obligations and in domestic and foreign money market obligations,
including repurchase agreements.
 
     The NASL Emerging Growth Trust is authorized to invest, under normal market
conditions, up to 20% of its total assets in domestic and foreign short-term
(one year or less remaining to maturity) and medium-term (five years or less
remaining to maturity) money market obligations and for temporary defensive
purposes may invest in these securities without limit. These instruments consist
of obligations issued or guaranteed by the U.S. government or a foreign
government, their agencies or instrumentalities; bank obligations (including
certificates of deposit, time deposits and bankers' acceptances of domestic or
foreign banks, domestic savings and loans and similar institutions) that are
high quality investments or, if unrated, deemed by Warburg Pincus to be high
quality investments; commercial paper rated no lower than A-2 by S&P or Prime-2
by Moody's or the equivalent from another major rating service or, if unrated,
of an issuer having an outstanding, unsecured debt issue then rated within the
three highest rating categories; and repurchase agreements with respect to the
foregoing.
 
     Investing in securities of emerging growth and small-sized companies may
involve greater risks since these securities may have limited marketability and,
thus, may be more volatile. Because small- and medium-sized companies normally
have fewer shares outstanding than larger companies, it may be more difficult
for the NASL Emerging Growth Trust to buy or sell significant amounts of such
shares without an unfavorable impact on prevailing prices. In addition, small-
and mediumsized companies are typically subject to a greater degree of changes
in earnings and business prospects than are larger, more established companies.
There is typically less publicly available information concerning small- and
medium-sized companies than for larger, more established ones. Securities of
issuers in "special
 
                                       35
<PAGE>   45
 
situations" also may be more volatile, since the market value of these
securities may decline in value if the anticipated benefits do not materialize.
Although investing in securities of emerging growth companies or "special
situations" offers potential for above-average returns if the companies are
successful, the risk exists that the companies will not succeed and the prices
of the companies' shares could significantly decline in value. Therefore, an
investment in the NASL Emerging Growth Trust may involve a greater degree of
risk than an investment in other mutual funds that seek capital appreciation by
investing in better-known, larger companies.
 
     The NASL Emerging Growth Trust will be subject to certain risks as a result
of its ability to invest up to 20% of its total assets in the securities of
foreign issuers. These risks are described under the caption "J. Additional
Information on Investment Policies and Techniques and Risk Factors -- Foreign
Securities." Moreover, substantial investments in foreign securities may have
adverse tax implications as described under "Additional Information About
NASL -- E. Tax Matters."
 
  Use of Hedging and Other Strategic Transactions
 
     The NASL Emerging Growth Trust is currently authorized to use all of the
investment strategies referred to under "J. Additional Information on Investment
Policies and Techniques and Risk Factors -- Hedging and Other Strategic
Transactions." However, it is not presently contemplated that any of these
strategies will be used to a significant degree by the NASL Emerging Growth
Trust.

Emerging Growth Trust and the Manulife Emerging Growth Fund, see "J. Additional
Information on Investment Policies and Techniques and Risk Factors."
 
D.  NASL BALANCED TRUST
 
     The investment objective of the NASL Balanced Trust is current income and
capital appreciation. Founders is the manager of the NASL Balanced Trust and
seeks to attain this objective by investing in a balanced portfolio of common
stocks, U.S. and foreign government obligations and a variety of corporate
fixed-income securities.
 
     Normally, the NASL Balanced Trust will invest a significant percentage (up
to 75%) of its total assets in common stocks, convertible corporate obligations,
and preferred stocks. The NASL Balanced Trust emphasizes investment in dividend-
paying common stocks with the potential for increased dividends, as well as
capital appreciation. The NASL Balanced Trust also may invest in non-dividend
paying companies if, in Founders' opinion, they offer better prospects for
capital appreciation.
 
     The NASL Balanced Trust may invest in convertible securities, preferred
stocks, bonds, debentures, and other corporate obligations when Founders
believes that these investments offer opportunities for capital appreciation.
Current income is also a factor in the selection of these securities.
 
     The NASL Balanced Trust will maintain a minimum of 25% of its total assets
in fixed-income, investment-grade securities rated Baa or higher by Moody's or
BBB or higher by S&P. There is, however, no limit on the amount of straight debt
securities in which the NASL Balanced Trust may invest. Up to 5% of the NASL
Balanced Trust's total assets may be invested in lower-grade (Ba or less by
Moody's, BB or less by S&P) or unrated straight debt securities, generally
referred to as junk bonds, where Founders determines that such securities
present attractive opportuni-
 
                                       38
<PAGE>   48
 
ties. The NASL Balanced Trust will not invest in securities rated lower than B.
Securities rated B generally lack characteristics of a desirable investment and
are deemed speculative with respect to the issuer's capacity to pay interest and
repay principal over a long period of time.
 
   
     The NASL Balanced Trust may also invest in convertible corporate
obligations and preferred stocks. Convertible securities and preferred stocks
purchased by the NASL Balanced Trust may be rated in medium and lower categories
by Moody's or S&P (Ba or lower by Moody's and BB or lower by S&P). The NASL
Balanced Trust currently does not intend to invest in securities rated lower
than B by Moody's or S&P. The NASL Balanced Trust may also invest in unrated
convertible securities and preferred stocks in instances in which Founders
believes that the financial condition of the issuer or the protection afforded
by the terms of the securities limits risk to a level similar to that of
securities eligible for purchase by the NASL Balanced Trust rated in categories
no lower than B. At no time will the NASL Balanced Trust have more than 5% of
its total assets invested in any fixed-income securities which are unrated or
are rated below investment grade either at the time of purchase or as a result
of a reduction in rating after purchase. The NASL Balanced Trust is not required
to dispose of debt securities whose ratings are downgraded below these ratings
subsequent to the NASL Balanced Trust's purchase of the securities, unless such
a disposition is necessary to reduce the NASL Balanced Trust's holdings of such
securities to less than 5% of its total assets. See "J. Additional Information
on Investment Policies and Techniques and Risk Factors -- High Yield (High Risk)
Securities." A description of the ratings used by Moody's and S&P is set forth
in the Appendix to this Prospectus/Proxy Statement.
    
 
     Up to 100% of the assets of the NASL Balanced Trust may be invested
temporarily in U.S. Government obligations, commercial paper, bank obligations,
repurchase agreements, and negotiable U.S. dollar-denominated obligations of
domestic and foreign branches of U.S. depository institutions, U.S. branches of
foreign depository institutions, and foreign depository institutions, in cash,
or in other cash equivalents, if Founders determines it to be appropriate for
purposes of enhancing liquidity or preserving capital in light of prevailing
market or economic conditions. The NASL Balanced Trust may also acquire
certificates of deposit and bankers' acceptances of banks which meet criteria
established by the NASL Board. While the NASL Balanced Trust is in a defensive
position, the opportunity to achieve capital growth will be limited, and, to the
extent that this assessment of market conditions is incorrect, the NASL Balanced
Trust will be foregoing the opportunity to benefit from capital growth resulting
from increases in the value of equity investments.
 
     The NASL Balanced Trust may invest without limit in ADRs and up to 30% of
its total assets in foreign securities (other than ADRs). The NASL Balanced
Trust will not invest more than 25% of its total assets in the securities of any
one country.
 
                                       39
<PAGE>   49
 
     The NASL Balanced Trust will be subject to special risks as a result of its
ability to invest up to 30% of its total assets in foreign securities, excluding
ADRs. These risks are described under the caption "J. Additional Information on
Investment Policies and Techniques and Risk Factors -- Foreign Securities."
Moreover, substantial investments in foreign securities may have adverse tax
implications as described under "Additional Information About NASL -- E. Tax
Matters" in this Prospectus/Proxy Statement.
 
  Use of Hedging and Other Strategic Transactions
 
     The NASL Balanced Trust is currently authorized to use all of the various
investment strategies referred to under "Hedging and Other Strategic
Transactions." The Statement of Additional Information contains a description of
these strategies and of certain risks associated therewith.

intermediate and long-term growth through capital appreciation and current
income by investing in common stocks and other equity securities of well
established companies with promising prospects for providing an above average
rate of return. MAC manages the NASL Common Stock Trust.
 
     In pursuit of its objective, the NASL Common Stock Trust will invest
principally in common stocks or in securities convertible into common stocks or
carrying rights or warrants to purchase common stock or to participate in
earnings.

In selecting investments, emphasis will be placed on companies with good
financial resources, strong balance sheets, satisfactory rates of return on
capital, good industry positions, superior management skills, and earnings that
tend to grow consistently. The NASL Common Stock Trust's investments are not
limited to any particular type or size of company, but high-quality growth
stocks are emphasized.
 
   
     Investments will be made primarily in securities listed on national
securities exchanges, but the NASL Common Stock Trust may purchase securities
traded in the United States over-the-counter market. When, in the opinion of
management, market or economic conditions warrant a defensive posture, the NASL
Common Stock Trust may place all or a portion of its assets in fixed-income
securities. The NASL Common Stock Trust may also maintain a portion of its
assets in cash or short-term debt securities pending selection of particular
long-term investments. The NASL Common Stock Trust may purchase securities on a
forward-commitment, when-issued or delayed-delivery basis. See "J. Additional
Information on Investment Policies and Techniques and Risk Factors --
When-Issued Securities ("Forward Commitments")" for additional information on
this practice.
    
 
     The NASL Common Stock Trust will be subject to certain risks as a result of
its ability to invest up to 100% of its total assets in the following types of
foreign securities: (i) U.S. dollar denominated obligations of foreign branches
of U.S. banks, (ii) securities represented by ADRs listed on a national
securities exchange or traded in the U.S. over-the-counter market, (iii)
securities of a corporation organized in a jurisdiction other than the U.S. and
listed on the New York Stock Exchange or NASDAQ or (iv) securities denominated
in U.S. dollars but issued by non U.S. issuers and issued under U.S. federal
securities regulations (for example, U.S. dollar denominated obligations issued
or guaranteed as to principal or interest by the Government of Canada or any
Canadian Crown agency). These risks are described under "J. Additional
Information on Investment Policies and Techniques and Risk Factors -- Foreign
Securities." Moreover, substantial investments in foreign securities may have
adverse tax implications as described under "Additional Information About
NASL -- E. Tax Matters."
 
  Use of Hedging and Other Strategic Transactions
 
     The NASL Common Stock Trust does not presently use any of the investment
strategies referred to under "J. Additional Information on Investment Policies
and Techniques and Risk Factors -- Hedging and Other Strategic Transactions."
 
  Differences between the NASL Common Stock Trust and the Manulife Common Stock
Fund
 
     Because the NASL Common Stock Trust has been created for the purpose of
operating as a successor to the Manulife Common Stock Fund in connection with
the Reorganization, the investment policies and restrictions of the NASL Common
Stock Trust and the Manulife Common Stock Fund are substantially identical,
 
                                       42

except for certain differences discussed below under "J. Additional Information
on Investment Policies and Techniques and Risk Factors."
 
F. NASL PACIFIC RIM EMERGING MARKETS TRUST
 
     The investment objective of the NASL Pacific Rim Emerging Markets Trust is
to achieve long-term growth of capital. MAC manages the NASL Pacific Rim
Emerging Markets Trust and seeks to achieve this investment objective by
investing in a diversified portfolio that is comprised primarily of common
stocks and equity-related securities of corporations domiciled in countries in
the Pacific Rim region. Current income from dividends and interest will not be
an important consideration in the selection of portfolio securities.
 
     In pursuit of its investment objective, the NASL Pacific Rim Emerging
Markets Trust will vary the geographical distribution of its investments based
upon the continuous evaluation of political, economic and market trends
throughout the world. Investments will be shifted among the world's capital
markets in accordance with the ongoing analyses of trends and developments
affecting such markets and securities. The NASL Pacific Rim Emerging Markets
Trust will invest primarily in companies domiciled in potentially all countries
of the Pacific Rim region. As used herein, the countries of the Pacific Rim
region are India, Pakistan, Japan, Hong Kong, Singapore, Malaysia, Thailand,
Indonesia, Australia, South Korea, Taiwan, Philippines, New Zealand and China.
 
     The NASL Pacific Rim Emerging Markets Trust will, under normal conditions,
invest at least 65% of its net assets in common stocks and equity-related
securities of established larger-capitalization non-U.S. companies that have
attractive long-term prospects for growth of capital. Equity-related securities
in which the NASL Pacific Rim Emerging Markets Trust may invest include:
preferred stocks, warrants and securities convertible into or exchangeable into
common stocks.
 
     The NASL Pacific Rim Emerging Markets Trust will invest in the securities
of issuers domiciled or primarily traded in at least five foreign countries if
it has invested at least 80% of its net assets in foreign issuers. If the NASL
Pacific Rim Emerging Markets Trust has less than 20% of its net assets in
foreign issuers, then all of such investment may be in issuers domiciled or
primarily traded in one country. If the NASL Pacific Rim Emerging Markets Trust
has at least 20% but less than 40% of its net assets in foreign issuers, then
such investment must be allocated to issuers domiciled or primarily traded in at
least two foreign countries. Similarly, if the NASL Pacific Rim Emerging Markets
Trust has at least 40% but less than 60% of its net assets invested in foreign
issuers, such investment must be allocated to at least three foreign countries.
Foreign investments must be allocated to at least four foreign countries if such
investments comprise at least 60% but less than 80% of the NASL Pacific Rim
Emerging Markets Trust's net assets.
 
     The NASL Pacific Rim Emerging Markets Trust will not invest more than 20%
of its net assets in securities of issuers domiciled or primarily traded in any
one
 
                                       43
<PAGE>   53
 
country, except that it may invest up to 35% of its net assets in issuers
domiciled or primarily traded in any one of the following countries: Australia,
France, Japan, the United Kingdom, or Germany.
 
     The NASL Pacific Rim Emerging Markets Trust may, for defensive purposes,
invest all or a portion of its assets in non-convertible fixed income securities
denominated in U.S. and non-U.S. dollars. These non-convertible fixed income
securities will include debt of corporations, foreign governments and
supranational organizations. The NASL Pacific Rim Emerging Markets Trust may
also maintain a portion of its assets in cash or short term debt securities
pending the selection of certain long-term investments.
 
     The NASL Pacific Rim Emerging Markets Trust will be subject to special
risks as a result of its ability to invest up to 100% of its total assets in
foreign securities. These risks are described under the caption "J. Additional
Information on Investment Policies and Techniques and Risk Factors -- Foreign
Securities." Moreover, substantial investments in foreign securities may have
adverse tax implications as described under "Additional Information About
NASL - E. Tax Matters."
 
  Use of Hedging and Other Strategic Transactions
 
     The NASL Pacific Rim Emerging Markets Trust may also purchase and sell the
following equity-related financial instruments: exchange-listed call and put
options on equity indices, over-the-counter ("OTC") and exchange-listed equity
index futures, OTC and exchange-listed call and put options on various
currencies in the portfolio, and OTC foreign currency futures contracts on
various currencies in the NASL Pacific Rim Emerging Markets Trust. The Statement
of Additional Information contains a description of these strategies and of
certain risks associated therewith.
 
  Differences between the NASL Pacific Rim Emerging Markets Trust and the
Manulife Pacific Rim Emerging Markets Fund
 
     Because the NASL Pacific Rim Emerging Markets Trust has been created for
the purpose of operating as a successor to the Manulife Pacific Rim Emerging
Markets Fund in connection with the Reorganization, the investment policies and
restrictions of the NASL Pacific Rim Emerging Markets Trust and the Manulife
Pacific Rim Emerging Markets Fund are substantially identical, except for
certain differences discussed below under "J. Additional Information on
Investment Policies and Techniques and Risk Factors."
 
G. NASL REAL ESTATE SECURITIES TRUST
 
     The investment objective of the NASL Real Estate Securities Trust is to
achieve a combination of long-term capital appreciation and satisfactory current
income by investing in real estate related equity and debt securities. MAC
manages
 
                                       44
<PAGE>   54
 
the NASL Real Estate Securities Trust and seeks to attain this objective by
investing principally in real estate investment trust ("REIT") equity and debt
securities and other securities issued by companies which invest in real estate
or interests therein.
 
   
     REITs are pooled investment vehicles which invest primarily in income
producing real estate or real estate related loans or interests. Investing in
REITs involves the risks associated with real estate investing, such as risks
relating to declines in real estate values, deterioration in general and local
economic conditions, overbuilding and increased competition, increases in
operating expenses and increases in interest rates, as well as certain unique
risks, such as risks relating to heavy cash flow dependency, defaults by
borrowers, self-liquidation and the possibility of failing to qualify for
exemption from tax for distributed income under the Code or failing to maintain
exemption from regulation under the 1940 Act. REITs are dependent on management
skills, are not diversified and are subject to the risks of financing projects.
They may have limited financial resources, trade less frequently and in a
limited volume and be subject to more abrupt or erratic price movements than
securities of larger issuers.
    
 
     The NASL Real Estate Securities Trust may also purchase the common stocks,
preferred stocks, convertible securities and bonds of companies operating in
industry groups relating to the real estate industry. This would include
companies engaged in the development of real estate, building and construction,
and other market segments related to real estate. The NASL Real Estate
Securities Trust will not invest directly in real property nor will it purchase
mortgage notes directly.
 
     Under normal circumstances, at least 65% of the value of the NASL Real
Estate Securities Trust's total assets will be invested in real estate related
equity and debt securities. When, in the opinion of MAC, market or economic
conditions warrant a defensive posture, the NASL Real Estate Securities Trust
may place all or a portion of its assets in fixed-income securities which may or
may not be real estate debt related securities. The NASL Real Estate Securities
Trust may also maintain a portion of its assets in cash or short-term debt
securities pending selection of particular long-term investments. The NASL Real
Estate Securities Trust may purchase securities on a forward-commitment,
when-issued or delayed-delivery basis. See "J. Additional Information on
Investment Policies and Techniques and Risk Factors -- When-Issued Securities
("Forward Commitments")" for additional information on this practice.
 
     The NASL Real Estate Securities Trust will be subject to certain risks as a
result of its ability to invest up to 100% of its total assets in the following
types of foreign securities: (i) U.S. dollar denominated obligations of foreign
branches of U.S. banks, (ii) securities represented by ADRs listed on a national
securities exchange or traded in the U.S. over-the-counter market, (iii)
securities of a corporation organized in a jurisdiction other than the U.S. and
listed on the New York Stock Exchange or NASDAQ or (iv) securities denominated
in U.S. dollars but issued by non U.S. issuers and issued under U.S. federal
securities regulations
 
                                       45
<PAGE>   55
 
(for example, U.S. dollar denominated obligations issued or guaranteed as to
principal or interest by the Government of Canada or any Canadian Crown agency).
These risks are described under the caption "J. Additional Information on
Investment Policies and Techniques and Risk Factors -- Foreign Securities" in
this Prospectus/Proxy Statement. Moreover, substantial investments in foreign
securities may have adverse tax implications as described under "Additional
Information About NASL - E. Tax Matters."
 
  Use of Hedging and Other Strategic Transactions
 
     The NASL Real Estate Securities Trust does not presently use any of the
investment strategies referred to under "J. Additional Information on Investment
Policies and Techniques and Risk Factors -- Hedging and Other Strategic
Transactions."
 
  Differences between the NASL Estate Securities Trust and the Manulife Real
Estate Securities Fund
 
     Because the NASL Real Estate Securities Trust has been created for the
purpose of operating as a successor to the Manulife Real Estate Securities Fund
in connection with the Reorganization, the investment policies and restrictions
of the NASL Real Estate Securities Trust and the Manulife Real Estate Securities
Fund are substantially identical, except for certain differences discussed below
under "J. Additional Information on Investment Policies and Techniques and Risk
Factors."
 
H. NASL CAPITAL GROWTH BOND TRUST
 
     The investment objective of the NASL Capital Growth Bond Trust is to
achieve growth of capital by investing in medium-grade or better debt
securities, with income as a secondary consideration. MAC manages the NASL
Capital Growth Bond Trust.
 
     The NASL Capital Growth Bond Trust differs from most "bond" funds in that
its primary objective is capital appreciation, not income. Opportunities for
capital appreciation will usually exist only when the levels of prevailing
interest rates are falling. During periods when MAC expects interest rates to
decline, the portfolio will invest primarily in intermediate-term and long-term
corporate and government debt securities. However, during periods when MAC
expects interest rates to rise or believes that market or economic conditions
otherwise warrant such action, the portfolio may invest substantially all of its
assets in short-term debt securities to preserve capital and maintain income.
The portfolio may also maintain a portion of its assets temporarily in cash or
short-term debt securities pending selection of particular long-term
investments.
 
     The NASL Capital Growth Bond Trust will be carefully positioned in relation
to the term of debt obligations and the anticipated movement of interest rates.
It is contemplated that at least 75% of the value of the NASL Capital Growth
Bond
 
                                       46
<PAGE>   56
 
Trust's total investment in corporate debt securities, excluding commercial
paper, will be represented by debt securities which have, at the time of
purchase, a rating within the four highest grades as determined by Moody's (Aaa,
Aa, A or Baa), S&P's (AAA, AA, A or BBB), or Fitch's Investors Service
("Fitch's") (AAA, AA, A or BBB) and debt securities of banks and other issuers
which, although not rated as a matter of policy by either Moody's, S&P's, or
Fitch's, are considered by MAC to have investment quality comparable to
securities receiving ratings within such four highest grades. Although the
portfolio does not intend to acquire or hold debt securities of below
investment-grade quality, shareholders should note that even bonds of the lowest
categories of investment-grade quality may have speculative characteristics, and
changes in economic conditions or other circumstances are more likely to lead to
a weakened capacity to make principal and interest payments than is the case
with higher-grade bonds. It should be further noted that should an obligation in
the NASL Capital Growth Bond Trust drop below investment grade, the NASL Capital
Growth Bond Trust will make every effort to dispose of it promptly so long as to
do so would not be detrimental to the NASL Capital Growth Bond Trust.
 
   
     Government obligations in which the NASL Capital Growth Bond Trust may
invest will be limited to those issued or guaranteed as to principal or interest
by the United States Government or its agencies or instrumentalities or by the
Government of Canada or any Canadian Crown agency. Any Canadian obligation
acquired by the NASL Capital Growth Bond Trust will be payable in U.S. dollars.
The NASL Capital Growth Bond Trust may purchase securities on a
forward-commitment, when-issued or delayed-delivery basis. See "J. Additional
Information on Investment Policies and Techniques and Risk
Factors -- When-Issued Securities ("Forward Commitments")" for additional
information on this practice.
    
 
     The NASL Capital Growth Bond Trust may purchase corporate debt securities
which carry certain equity features, such as conversion or exchange rights or
warrants for the acquisition of stock of the same or a different issuer or
participations based on revenues, sales, or profits. The NASL Capital Growth
Bond Trust will not exercise any such conversion, exchange or purchase rights
if, at the time, the value of all equity interests so owned would exceed 10% of
the value of the NASL Capital Growth Bond Trust's total assets.
 
     The NASL Capital Growth Bond Trust will be subject to certain risks as a
result of its ability to invest up to 100% of its total assets in the following
types of foreign securities: (i) U.S. dollar denominated obligations of foreign
branches of U.S. banks, (ii) securities represented by American Depositary
Receipts listed on a national securities exchange or traded in the U.S.
over-the-counter market, (iii) securities of a corporation organized in a
jurisdiction other than the U.S. and listed on the New York Stock Exchange or
NASDAQ ("Interlisted Securities") or (iv) securities denominated in U.S. dollars
but issued by non U.S. issuers and issued under U.S. federal securities
regulations (for example, U.S. dollar denominated obligations issued or
guaranteed as to principal or interest by the Government
 
                                       47

of Canada or any Canadian Crown agency). These risks are described under the
caption "J. Additional Information on Investment Policies and Techniques --
Foreign Securities." Moreover, substantial investments in foreign securities may
have adverse tax implications as described under "Additional Information About
NASL - E. Tax Matters."
 
  Use of Hedging and Other Strategic Transactions
 
     The NASL Capital Growth Bond Trust does not presently use any of the
investment strategies referred to under "J. Additional Information on Investment
Policies and Techniques -- Hedging and Other Strategic Transactions."
 
  Differences between the NASL Capital Growth Bond Trust and the Manulife
Capital Growth Bond Fund
 
     Because the NASL Capital Growth Bond Trust has been created for the purpose
of operating as a successor to the Manulife Capital Growth Bond Fund in
connection with the Reorganization, the investment policies and restrictions of
the NASL Capital Growth Bond Trust and the Manulife Capital Growth Bond Fund are
substantially identical, except for certain differences discussed below under
"J. Additional Information on Investment Policies and Techniques and Risk
Factors."
 
I. NASL EQUITY INDEX TRUST
 
     The investment objective of the NASL Equity Index Trust is to achieve
investment results which approximate the total return of publicly traded common
stocks in the aggregate, as represented by the Standard & Poor's 500 Composite
Stock Price Index (the "Index"). MAC manages the NASL Equity Index Trust.
 
     The NASL Equity Index Trust is designed to provide an economical and
convenient means of maintaining a widely diversified investment in the United
States equity market as part of an overall investment strategy. The NASL Equity
Index Trust uses the Index as its standard performance comparison because it
represents more than 70% of the total market value of all publicly traded common
stocks in the United States and is widely viewed among investors as
representative of the performance of publicly traded common stocks in the United
States.
 
     The Index is composed of 500 selected common stocks, over 95% of which are
listed on the New York Stock Exchange. The Index is an unmanaged index of common
stock prices. The performance of the Index is based on changes in the prices of
stocks comprising the Index and assumes the reinvestment of all dividends paid
on such stocks. Taxes, brokerage, commissions and other fees are disregarded in
computing the level of the Index. Standard & Poor's selects the stocks to be
included in the Index on a proprietary basis but does incorporate such factors
as the market capitalization and trading activity of each stock and its adequacy
as representative of stocks in a particular industry group. Stocks in the Index
are
 
                                       48
<PAGE>   58
 
weighted according to their market capitalization (i.e., the number of shares
outstanding multiplied by the stock's current price).(1)
 
     The Index fluctuates in value with changes in the market value of the 500
stocks included in the Index at any point in time. An investment in the NASL
Equity-Index Trust involves risks similar to the risks of investing directly in
the stocks included in the Index.
 
     MAC will not attempt to "manage" the NASL Equity Index Trust in the
traditional portfolio management sense which generally involves the buying and
selling of securities based upon investment analysis of economic, financial and
market factors. Instead, the NASL Equity Index Trust, utilizing a "passive" or
"indexing" investment approach, attempts to duplicate the performance of the
Index. The adverse financial situation of a company will not directly result in
its elimination from the NASL Equity Index Trust unless, of course, the company
in question is removed from the Index. Conversely, the projected superior
financial performance of a company would not normally lead to an increase in the
NASL Equity Index Trust's holdings of the company. Under normal circumstances,
the net assets of the NASL Equity Index Trust will be invested in any
combination of the following investments: 1) representative common stocks, 2)
Standard & Poor's 500 Futures Contracts and 3) Standard & Poor's Depository
Receipts(R).
 
     With regard to the portion of the NASL Equity Index Trust invested in
common stocks, the method used to select investments for the NASL Equity Index
Trust involves investing in common stocks in approximately the order of their
respective market value weightings in the Index, beginning with those having the
highest weightings. For diversification purposes, the NASL Equity Index Trust
can purchase stocks with smaller weightings in order to represent other sectors
of the Index. The NASL Equity Index Trust will invest only in those stocks, and
in such amounts, as MAC deems necessary and appropriate in order for the NASL
Equity Index Trust to approximate the performance of the Index.
 
     There is no minimum or maximum number of stocks included in the Index which
the NASL Equity Index Trust must hold. Under normal circumstances, it is
expected that the portion of the NASL Equity Index Trust invested in stocks
would hold between 300 and 500 different stocks included in the Index. The NASL
Equity Index Trust may compensate for the omission of a stock that is included
in the Index, or for purchasing stocks in other than the same proportion that
they are represented in the Index, by purchasing stocks that are believed to
have characteristics that correspond to those of the omitted stocks. The NASL
Equity Index Trust may invest in short-term debt securities to maintain
liquidity or pending investment in stocks or Standard & Poor's Stock Index
Futures Contracts (S&P 500 Futures Contracts).

     Tracking error is measured by the difference between the total return for
the Index and the total return for the NASL Equity Index Trust after deductions
of fees and expenses. All tracking error deviations are reviewed to determine
the effectiveness of investment policies and techniques. Tracking error is
reviewed at least weekly and more frequently if such a review is indicated by
significant cash balance changes, market conditions or changes in the
composition of the Index. If deviation accuracy is not maintained, the NASL
Equity Index Trust will rebalance its composition by selecting securities which,
in the opinion of MAC, will provide a more representative sampling of the
capitalization of the securities in the Index as a whole or a more
representative sampling of the sector diversification in the Index.
 
     S&P licenses certain trademarks and trade names to NASL but disclaims any
responsibility or liability to NASL and its shareholders.
 
     The NASL Equity Index Trust is not sponsored, endorsed, sold or promoted by
S&P. S&P makes no representation or warranty, express or implied, to the
shareholders of the NASL Equity Index Trust or any member of the public
regarding the advisability of investing in securities generally or in the NASL
Equity Index Trust particularly or the ability of the S&P 500 Index to track
general stock market performance. S&P's only relationship to NASL is the
licensing of certain trademarks and trade names of S&P and of the S&P 500 Index
which is determined, composed and calculated by S&P without regard to NASL or
the NASL Equity Index Trust. S&P has no obligation to take the needs of NASL or
the shareholders of the NASL Equity Index Trust into consideration in
determining, composing or calculating the S&P 500 Index. S&P is not responsible
for and has not participated in the determination of the prices and amount of
shares of the NASL Equity Index Trust or the timing of the issuance or sale of
the shares of the NASL Equity Index Trust or in the determination or calculation
of the equation by which shares of the NASL Equity Index Trust are to be
converted into cash. S&P has no obligation or liability in connection with the
administration, marketing or trading of the NASL Equity Index Trust.
 
     S&P does not guarantee the accuracy and/or the completeness of the S&P 500
Index or any data included therein and S&P shall have no liability for any
errors, omissions, or interruptions therein. S&P makes no warranty, express or
implied, as to results to be obtained by NASL, shareholders of the NASL Equity
Index Trust, or any other person or entity from the use of the S&P 500 Index or
any data included therein. S&P makes no express or implied warranties, and
expressly disclaims all warranties of merchantability or fitness for a
particular purpose or use with respect to the S&P 500 Index or any data included
therein. Without limiting any of the foregoing, in no event shall S&P have any
liability for any special, punitive, indirect, or consequential damages
(including lost profits), even if notified of the possibility of such damages.

  Use of Hedging and Other Strategic Transactions
 
     The NASL Equity Index Trust may (i) invest any portion of its net assets in
S&P 500 Futures Contracts until the NASL Equity Index Trust reaches $25 million
in net assets and (ii) once the NASL Equity Index Trust reaches $25 million in
net assets, invest no more than 20% of its net assets in S&P 500 Futures
Contracts. A description of this investment strategy appears under "J.
Additional Information on Investment Policies and Techniques and Risk
Factors -- Hedging and Other Strategic Transactions" below in this
Prospectus/Proxy Statement and under "Hedging and Other Strategic Transactions"
in the Statement of Additional Information.
 
  Differences between the NASL Equity Index Trust and the Manulife Equity Index
Fund
 
     Because the NASL Equity Index Trust has been created for the purpose of
operating as a successor to the Manulife Equity Index Fund in connection with
the Reorganization, the investment policies and restrictions of the NASL Equity
Index Trust and the Manulife Equity Index Fund are substantially identical,
except for certain differences discussed below under "J. Additional Information
on Investment Policies and Techniques and Risk Factors."
 
J. ADDITIONAL INFORMATION ON INVESTMENT POLICIES AND
  TECHNIQUES AND RISK FACTORS
 
  INVESTMENT RESTRICTIONS GENERALLY
 
     NASL is subject to a number of restrictions in pursuing its investment
objectives and policies. Except as noted, the Manulife Portfolios are subject to
similar restrictions. The following is a brief summary of certain restrictions
that may be of interest to contractholders. 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 NASL Portfolios and to
NASL 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/Proxy
Statement and in the Statement of Additional Information are not fundamental, so
that the NASL Board may change them without shareholder approval. Fundamental
policies may not be changed without the affirmative vote of a majority of the
outstanding voting securities.
 
     There are also diversification and other requirements for all of the NASL
Portfolios imposed by the federal tax laws, as described under "Additional
Information about NASL -- E. Tax Matters." The Manulife Portfolios are subject
to the same requirements.
 
                                       51
<PAGE>   61
 
  Industry Concentration
 
     NASL Portfolios.  As a matter of fundamental policy, each NASL Portfolio
other than the NASL Real Estate Securities Trust is prohibited from investing
more than 25% of its total assets in the securities of issuers having their
principal activities in any particular industry (with exceptions for U.S.
Government securities and obligations of domestic branches of U.S. banks and
savings and loan associations).
 
     Manulife Portfolios.  While the corresponding Manulife Portfolios are
subject to a similar fundamental policy, NASL, unlike MSF, has determined to
forego the exclusion with respect to obligations of domestic branches of U.S.
savings and loan associations and to limit the exclusion with respect to
obligations of domestic branches of U.S. banks to the NASL Money Market Trust.
 
  Borrowing
 
   
     NASL Portfolios.  Each NASL Portfolio, as a matter of fundamental policy,
is prohibited from borrowing money, except for temporary or emergency purposes
(but not for leveraging) and then not in excess of 33 1/3% of the value of the
total assets of a NASL Portfolio at the time the borrowing is made. In addition,
each NASL Portfolio, as a matter of fundamental policy, may borrow in connection
with reverse repurchase agreements (described under "Repurchase Agreements and
Reverse Repurchase Agreements" below), mortgage dollar rolls (described under
"Mortgage Dollar Rolls" below) and other similar transactions. Reverse
repurchase agreements and mortgage dollar rolls may be considered a form of
borrowing and will be treated as a borrowing for purposes of the restriction on
borrowing in excess of 33 1/3% of the value of the total assets of a NASL
Portfolio. A NASL Portfolio will not purchase securities while borrowings (other
than reverse repurchase agreements, mortgage dollar rolls and similar
transactions) exceed 5% of total assets.
    
 
     Manulife Portfolios.  In contrast, each Manulife Portfolio, as a matter of
fundamental policy, is prohibited from borrowing money except from banks for
temporary or emergency purposes. As a matter of fundamental policy, borrowing by
a Manulife Portfolio may not exceed 10% of the value of such Manulife
Portfolio's total assets at the time the borrowing is made. In addition, each
Manulife Portfolio other than the Manulife International Fund and Manulife
Pacific Rim Emerging Markets Fund is subject to a fundamental investment
restriction which prohibits additional investments during any period that its
borrowings exceed 5% of the value of its total assets.
 
  Issuer Diversification
 
   
     NASL Portfolios.  Each of the NASL Portfolios other than the NASL Emerging
Growth Trust is prohibited as a matter of fundamental policy from purchasing
securities of any issuer if the purchase would cause more than 5% of the value
of a NASL Portfolio's total assets to be invested in the securities of any one
    
 
                                       52
<PAGE>   62
    
issuer (excluding U.S. Government securities) or cause more than 10% of the
voting securities of the issuer to be held by a NASL Portfolio, except that up
to 25% of the value of each NASL Portfolio's total assets (except the NASL Money
Market Trust) may be invested without regard to this restriction.
 
     Manulife Portfolios.  A similar fundamental investment restriction applies
to each of the Manulife Portfolios, including the Manulife Emerging Growth Fund,
although, unlike NASL, MSF excludes bank obligations from such restriction.
     

  Investments in Real Estate-Related Securities
 
     NASL Portfolios.  As a matter of fundamental policy, each NASL Portfolio
may not purchase or sell real estate, except that each NASL Portfolio may invest
in securities issued by companies which invest in real estate or interests
therein and each of the NASL Portfolios other than the NASL Money Market Trust
may invest in mortgages and mortgage backed securities.
 
     Manulife Portfolios.  Each Manulife Portfolio is subject to a similar
fundamental investment restriction, except that only the Manulife Balanced
Assets Fund may invest in mortgage backed securities.
 
  Investments in Commodities
 
     NASL Portfolios.  Each NASL Portfolio is subject to a fundamental
investment restriction which prohibits the purchase and sale of commodities or
commodity contracts, except that each NASL Portfolio other than the NASL Money
Market Trust may purchase and sell futures contracts on financial indices and
options on such futures contracts and may purchase and sell futures contracts on
foreign currencies and options on such futures contracts, and the NASL Equity
Index Trust may purchase and sell S&P 500 Stock Index Futures Contracts.
 
     Manulife Portfolios.  The corresponding Manulife Portfolios are similarly
restricted as a matter of fundamental policy, but only the Manulife
International Fund and Manulife Pacific Rim Emerging Markets Fund are provided
with similar exceptions from such restriction.
 
  Investments in Illiquid Securities
 
     NASL Portfolios.  Restrictions that apply to all NASL Portfolios and that
are not fundamental include a prohibition on knowingly investing more than 15%
of the net assets of a NASL Portfolio (10% in the case of the Money Market
Trust) in "illiquid" securities (including repurchase agreements maturing in
more than seven days but excluding master demand notes).
 
     Manulife Portfolios.  In contrast, each of the Manulife Portfolios other
than the Manulife International Fund and Manulife Pacific Rim Emerging Markets
Fund is prohibited as a matter of nonfundamental policy from knowingly investing
in securities or other investments, including repurchase agreements maturing in
 
                                       53
<PAGE>   63
 
more than seven days, that are subject to legal or contractual restrictions upon
resale or are otherwise not readily marketable.
 
  Pledging Assets
 
     NASL Portfolios.  Each NASL Portfolio is prohibited as a matter of
nonfundamental policy from pledging, hypothecating, mortgaging or transferring
more than 10% of its total assets as security for indebtedness (except that the
applicable percent is 33 1/3% in the case of the NASL International Stock Trust
and 15% in the case of the NASL Balanced Trust).
 
     Manulife Portfolios.  Each Manulife Portfolio is subject to a similar
nonfundamental investment restriction, except that the applicable percent
limitation is 10% for every Manulife Portfolio.
 
  Investments in other Funds
 
     NASL Portfolios.  As a matter of nonfundamental policy, each NASL Portfolio
may not purchase 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 NASL Portfolio's total assets to be
invested in investment company securities.
 
     Manulife Portfolios.  In contrast, each Manulife Portfolio other than the
Manulife Equity Index Fund is subject to a nonfundamental restriction
prohibiting it from purchasing securities of other investment companies except
in connection with a merger, consolidation or reorganization, and the Manulife
Equity Index Fund is permitted to invest up to 5% of its assets in Standard &
Poor's Depositary Receipts.
 
  Money Market Trust Restrictions
 
     NASL Portfolios.  Finally, the NASL Money Market Trust is subject to
certain restrictions required by Rule 2a-7 under the 1940 Act. In order to
comply with such restrictions, the NASL Money Market Trust will, inter alia, 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 the Rule 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 the
Rule, 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.
 
     Manulife Portfolios.  The Manulife Money-Market Fund is subject to the same
restrictions under Rule 2a-7.

     The following is a description of certain investment policies subject to
investment restrictions that may be of particular interest to contractholders.
 
  ADDITIONAL INVESTMENT RESTRICTIONS ON BORROWING AND FOREIGN INVESTING
 
     In order to comply with limitations imposed by the State of California
Insurance Department, each of the NASL Portfolios, like the corresponding
Manulife Portfolios, is subject to the following restrictions on borrowing and
foreign investments. These restrictions are nonfundamental and may be changed
without shareholder approval.
 
     Borrowing.  Each NASL Portfolio will not borrow money except that each NASL
Portfolio may borrow in an amount (i) up to 25% of the NASL Portfolio's net
assets for temporary purposes to facilitate redemptions (not for leveraging) and
(ii) up to 10% of the NASL Portfolio's net assets in connection with reverse
repurchase agreements, mortgage dollar rolls and other similar transactions.
This limitation is more restrictive than NASL's fundamental restriction on
borrowing.
 
     Foreign Securities.  Each NASL Portfolio will comply with the following
restrictions:
 
     (i) A NASL Portfolio will be invested in a minimum of five different
     foreign countries at all times. However, this minimum is reduced to four
     when foreign country investments comprise less than 80% of the NASL
     Portfolio's net asset value; to three when less than 60% of such value; to
     two when less than 40%; and to one when less than 20%.
 
     (ii) Except as set forth in items (iii) and (iv) below, a NASL Portfolio
     will have no more than 20% of its net asset value invested in securities of
     issuers located in any one country.
 
     (iii) A NASL Portfolio may have an additional 15% of its net asset value
     invested in securities of issuers located in any one of the following
     countries (to the extent such investment is consistent with the investment
     policies of the NASL Portfolio): Australia, Canada, France, Japan, the
     United Kingdom or West Germany.
 
     (iv) A NASL Portfolio's investments in United States issuers are not
     subject to these foreign country diversification restrictions.
 
HIGH YIELD (HIGH RISK) SECURITIES
 
     General.  The NASL Balanced Trust, unlike the Manulife Balanced Assets
Fund, may invest up to 5% of its assets, in "high yield" (high risk) 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
 
                                       55
<PAGE>   65
 
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. 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 NASL Balanced
Trust with a commensurate effect on the value of the NASL Balanced Trust's
shares.
 
     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 ability
of the NASL Balanced Trust to dispose of particular portfolio investments and
may limit its ability to obtain accurate market quotations for purposes of
valuing securities and calculating net asset value. If the NASL Balanced Trust
is not able to obtain precise or accurate market quotations for a particular
security, it will become more difficult for the NASL Board to value its
investment portfolio and the NASL Board may have to use a greater degree of
judgment in making such valuations. Less liquid secondary markets may also
affect the NASL Balanced Trust's ability to sell securities at their fair value.
In addition, the NASL Balanced Trust may invest up to 15% 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 the NASL Balanced Trust's assets invested in illiquid securities
may increase.
 
   
     Because certain NASL Portfolios will invest primarily in fixed-income
securities, the net asset value of their 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.
    
 
     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
 
                                       56
<PAGE>   66
 
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.
 
   
    
FOREIGN SECURITIES
 
     Each NASL Portfolio, other than the NASL Equity Index Trust, may invest in
securities of foreign issuers to the extent stated above under the description
of such NASL Portfolio. Such foreign securities may be denominated in foreign
currencies, except with respect to the NASL Money Market Trust which may only
invest in U.S. dollar-denominated securities of foreign issuers. In the case of
the NASL Balanced Trust, ADRs and U.S. dollar denominated securities are not
included in its percentage limitation on foreign investments.
 
     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 Depository
Receipts ("ADRs", "EDRs" and "GDRs"). 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 NASL Portfolios may invest may be
sponsored or unsponsored. There may be less information available about foreign
issuers of unsponsored ADRs.
 
     Securities of foreign issuers also include EDRs and GDRs, which 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
necessarily quoted in the same currency as the underlying security.
 
     Foreign securities may be subject to foreign government taxes which reduce
their attractiveness. See "Additional Information about NASL -- E. Tax Matters."
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
NASL Portfolios may invest in securities denominated or quoted in currencies
other than the United States dollar, changes in foreign currency exchange rates
may affect the value of investments in
 
                                       57
<PAGE>   67
 
the portfolio and the unrealized appreciation or depreciation of investments
insofar as United States 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 NASL 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 United States exchanges and securities of foreign issuers are generally
less liquid and more volatile than those of comparable domestic issuers. 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 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 NASL 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
NASL Portfolio is uninvested and no return is earned thereon. The inability of a
NASL Portfolio to make intended security purchases due to settlement problems
could cause the NASL Portfolio to miss attractive investment opportunities.
Inability to dispose of portfolio securities due to settlement problems could
result in losses to a NASL Portfolio due to subsequent declines in values of the
portfolio securities or, if the NASL 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 NASL 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 NASL Portfolio of
any restrictions on investments.
 
   
    
     In contrast, each of the Manulife Portfolios may invest without limitation
in securities of foreign issuers, but, with respect to all of the Manulife
Portfolios except the Manulife International Fund and Manulife Pacific Rim
Emerging Markets Fund, such investments are restricted as a matter of
nonfundamental policy to securities of the following types: (i) U.S. dollar
denominated obligations of foreign
 
                                       58
<PAGE>   68
 
branches of U.S. banks, (ii) securities represented by ADRs listed on a national
securities exchange or traded in the U.S. over-the-counter market, (iii)
securities of a corporation organized in a jurisdiction other than the U.S. and
listed on the New York Stock Exchange or NASDAQ or (iv) securities denominated
in U.S. dollars but issued by non-U.S. issuers and issued under U.S. federal
securities regulations (for example, U.S. dollar denominated obligations issued
or guaranteed as to principal or interest by the Government of Canada or any
Canadian Crown agency). The Manulife Equity Index Fund presently does not invest
in foreign securities because none are included in the Standard & Poor's 500
Composite Stock Price Index.
 
WARRANTS
 
   
     Subject to certain restrictions, each of the NASL Portfolios except the
NASL Money Market Trust may purchase warrants, including warrants traded
independently of the underlying securities. Warrants are rights to purchase
securities at specific prices valid for a specific period of time. Their prices
do not necessarily move parallel to the prices of the underlying securities, and
warrant holders receive no dividends and have no voting rights or rights with
respect to the assets of an issuer. Warrants cease to have value if not
exercised prior to the expiration date.
 
     The Manulife International Fund, Manulife Common Stock Fund, Manulife
Pacific Rim Emerging Markets Fund and Manulife Emerging Growth Fund also may
purchase warrants.
    

LENDING SECURITIES
 
     Each NASL Portfolio may lend its securities so long as such loans do not
represent in excess of 33 1/3% of a NASL Portfolio's total assets. This is a
fundamental policy. In contrast, as a matter of fundamental policy, each
Manulife Portfolio may lend its securities so long as such loans do not
represent in excess of 20% of a Manulife Portfolio's total assets. The procedure
for lending securities is for the borrower to give the lending NASL Portfolio
collateral consisting of cash, cash equivalents or securities issued or
guaranteed by the U.S. government or its agencies or instrumentalities. The
lending NASL Portfolio may invest the cash collateral and earn additional income
or receive an agreed upon fee from a borrower which has delivered cash
equivalent collateral. NASL anticipates that its securities will be loaned only
under the following conditions: (1) the borrower must furnish collateral equal
at all times to the market value of the securities loaned and the borrower must
agree to increase the collateral on a daily basis if the securities increase in
value; (2) the loan will be made in accordance with New York Stock Exchange
rules, which presently require the borrower, after notice, to redeliver the
securities within five business days; and (3) the NASL Portfolio making the loan
may pay reasonable service, placement, custodian or other fees in connection
with loans of securities and share a portion of the interest from these
investments with the borrower of the securities. As with other extensions of
credit there are risks of delay in recovery or
 
                                       59
<PAGE>   69
 
even loss of rights in the collateral should the borrower of the securities fail
financially.
 
WHEN-ISSUED SECURITIES ("FORWARD COMMITMENTS")
 
     In order to help ensure the availability of suitable securities, each of
the NASL Portfolios, like the corresponding Manulife 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 NASL 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 NASL
Portfolio purchasing securities on a when-issued or forward delivery basis will
take delivery of the securities, but the NASL Portfolio may sell the securities
before the settlement date, if such action is deemed advisable. In general, a
NASL Portfolio does not pay for the securities or start earning interest on them
until the obligations are 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 NASL Portfolio will establish a
segregated account consisting of cash or 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 NASL 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 NASL Portfolio may purchase
when-issued or forward delivery securities. Except as may be imposed by these
factors, there is no limit on the percent of a NASL Portfolio's total assets
that may be committed to such transactions.
 
REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS
 
     Each of the NASL Portfolios, like the corresponding Manulife Portfolios,
may enter into repurchase agreements. Repurchase agreements involve the
acquisition by a NASL Portfolio of debt securities subject to an agreement to
resell them at an agreed-upon price. Under a repurchase agreement, at the time a
NASL 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 NASL Board) 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.
 
     The NASL Board has adopted procedures that establish certain
creditworthiness, asset and collateralization requirements for the
counterparties to a NASL Portfolio's repurchase agreements. The NASL Board will
regularly monitor the use
 
                                       60
<PAGE>   70
 
of repurchase agreements and the NASL subadvisers will, pursuant to procedures
adopted by the NASL Board, 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 NASL 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.
 
     Each of the NASL Portfolios, unlike the corresponding Manulife Portfolios,
may enter into "reverse" repurchase agreements. Under a reverse repurchase
agreement, a NASL Portfolio may sell a debt security and agree to repurchase it
at an agreed upon time and at an agreed upon price. The NASL Portfolio retains
record ownership of the security and the right to receive interest and principal
payments thereon. At an agreed upon future date, the NASL Portfolio repurchases
the security by remitting the proceeds previously received, plus interest. The
difference between the amount the NASL Portfolio receives for the security and
the amount it pays on repurchase is deemed to be payment of interest. The NASL
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. While a reverse repurchase agreement may
be considered a form of leveraging and may, therefore, increase fluctuations in
a NASL Portfolio's net asset value per share, each NASL Portfolio will cover the
transaction as described above.
 
MORTGAGE DOLLAR ROLLS
 
     Each of the NASL Portfolios (except the NASL Money Market Trust), unlike
the corresponding Manulife Portfolios, may enter into mortgage dollar rolls.
Under a mortgage dollar roll, a NASL Portfolio sells mortgage-backed securities
for delivery in the future (generally within 30 days) and simultaneously
contracts to repurchase substantially similar (same type, coupon and maturity)
securities on a specified future date. During the roll period, the NASL
Portfolio forgoes principal and interest paid on the mortgage-backed securities.
A NASL Portfolio is compensated by the difference between the current sale price
and the lower forward price for the future purchase (often referred to as the
"drop") as well as by the interest earned on the cash proceeds of the initial
sale. A NASL Portfolio may also be compensated by receipt of a commitment fee. A
portfolio may only enter into covered rolls. A "covered roll" is a specific type
of dollar roll for which there is an
 
                                       61
<PAGE>   71
 
offsetting cash or cash equivalent security position which matures on or before
the forward settlement date of the dollar roll transaction. Dollar roll
transactions involve the risk that the market value of the securities sold by
the portfolio may decline below the repurchase price of those securities. While
a mortgage dollar roll may be considered a form of leveraging, and may,
therefore, increase fluctuations in a NASL Portfolio's net asset value per
share, each NASL Portfolio will cover the transaction as described above.
 
HEDGING AND OTHER STRATEGIC TRANSACTIONS
 
   
     Individual NASL 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 NASL Portfolio. The description in this
Prospectus/Proxy Statement of each NASL Portfolio indicates which, if any, of
these types of transactions may be used by such NASL Portfolio, and the
discussion of differences from the corresponding Manulife Portfolio following
each such description indicates if there are differences regarding the use of
these types of transactions. Limitations on the portion of a NASL 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 NASL 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,
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/Proxy Statement as "Hedging and
Other Strategic Transactions"). A NASL Portfolio's interest rate transactions
may take the form of swaps, caps, floors and collars, and a NASL 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 be used to attempt to protect
against possible changes in the market value of securities held or to be
purchased by a NASL Portfolio resulting from securities markets or currency
exchange rate fluctuations, to protect a NASL 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 NASL
Portfolio's securities or to establish a position in the derivatives markets as
a temporary substitute for purchasing or selling particular securities. A NASL
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
 
                                       62
<PAGE>   72
 
be a function of numerous variables, including market conditions. The ability of
a NASL Portfolio to utilize Hedging and Other Strategic Transactions
successfully will depend on, in addition to the factors described above, its
subadviser's ability to predict pertinent market movements, which cannot be
assured. These skills are different from those needed to select a NASL
Portfolio's securities. None of the NASL 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")) and Hedging and Other Strategic
Transactions involving futures contracts and options on futures contracts will
be purchased, sold or entered into only for bona fide hedging, risk management
or appropriate portfolio management purposes and not for speculative purposes.
The use of certain Hedging and Other Strategic Transactions will require that a
NASL Portfolio segregate cash, liquid high grade debt obligations or other
assets to the extent a NASL 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 NASL Portfolios is precluded as a matter of nonfundamental
policy from investing in excess of 15% of its net assets in securities that are
not readily marketable, except that the NASL Money Market Trust may not invest
in excess of 10% of its net assets in such securities. Excluded from the 10% and
15% 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
pursuant to the Securities Act of 1933 ("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 NASL's investment restriction
is a determination to be made by the NASL subadvisers subject to the NASL
Board's oversight and for which the NASL Board is ultimately responsible. The
NASL subadvisers will also monitor the liquidity of Rule 144A securities held by
the NASL Portfolios for which they are responsible. To the extent Rule 144A
securities held by a NASL Portfolio should become illiquid because of a lack of
interest on the part of qualified institutional investors, the overall liquidity
of the NASL Portfolio could be adversely affected. In addition, the NASL Money
Market Trust 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 its disposition under federal securities
law, and is generally sold to institutional investors, such as NASL, 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
 
                                       63
<PAGE>   73
 
an exempt transaction. Section 4(2) commercial paper is normally resold to other
institutional investors like the NASL Money Market Trust 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 NASL Money Market Trust's
subadviser believes that Section 4(2) commercial paper meets its criteria for
liquidity and is quite liquid. The NASL Money Market Trust intends, therefore,
to treat Section 4(2) commercial paper as liquid and not subject to the
investment limitation applicable to illiquid securities. The NASL Money Market
Trust's subadviser will monitor the liquidity of 4(2) commercial paper held by
the NASL Money Market Trust, subject to the NASL Board's oversight and for which
the NASL Board is ultimately responsible.
 
     In contrast, each of the Manulife Portfolios other than the Manulife
International Fund and Manulife Pacific Rim Emerging Markets Fund is prohibited
as a matter of nonfundamental policy from knowingly investing in securities or
other investments, including repurchase agreements maturing in more than seven
days, that are subject to legal or contractual restrictions upon resale or are
otherwise not readily marketable. While such restriction does not apply with
respect to the Manulife International Fund and Manulife Pacific Rim Emerging
Markets Fund, such Manulife Portfolios are not authorized to treat Rule 144A
securities or Section 4(2) commercial paper as liquid.
 
                 COMPARATIVE INFORMATION ON SHAREHOLDER RIGHTS
 
     NASL is a Massachusetts business trust and is therefore governed by its
declaration of trust ("Declaration of Trust") and By-laws and by Massachusetts
law whereas MSF is a Maryland corporation and is therefore governed by its
articles of incorporation ("Articles"), By-laws and Maryland law. Certain
differences between the two forms of organization and governing corporate
documents are summarized below. Both MSF and NASL are, and following the
Reorganization NASL will continue to be, governed by the 1940 Act.
 
     Shareholder Liability.  Under Maryland law, MSF shareholders have no
personal liability for MSF's acts or obligations. Under Massachusetts law,
shareholders of NASL could, under certain circumstances, be held personally
liable for the obligations of NASL. However, the Declaration of Trust disclaims
shareholder liability for acts or obligations of NASL, and requires that notice
of such disclaimer be given in each agreement, obligation, or instrument entered
into or executed by NASL or the Trustees. Moreover, the Declaration of Trust
provides for indemnification out of NASL property for all losses and expenses of
any shareholder held personally liable for the obligations of NASL. Thus, the
risk of a shareholder's incurring financial loss on account of shareholder
liability is considered by NASL to be remote, since it is limited to
circumstances in which the disclaimer is inoperative, inadequate insurance
existed (e.g., fidelity bonding and errors and omissions insurance) and NASL
itself is unable to meet its obligations.

     Shares.  Interests in MSF are represented by transferable shares of common
stock, par value $.01 per share. The Articles authorize MSF to issue
1,000,000,000 shares of common stock. The MSF Board may, without shareholder
approval, increase or decrease the number of authorized shares and divide
authorized but unissued stock into an unlimited number of separate portfolios or
series, and classes thereof. Currently, all the authorized stock of MSF is
divided into nine separate series (corresponding to the nine Manulife
Portfolios, and none of these series is further subdivided into classes). Each
share of a Manulife Portfolio represents an equal proportionate interest in that
Manulife Portfolio's investment portfolio with the other shares of the same
Manulife Portfolio. Each share of a Manulife Portfolio is entitled to dividends
and distributions out of the assets of that Manulife Portfolio, as declared by
the MSF Board in its discretion. Fractional shares have proportionate rights to
full shares. Generally, shares will be voted in the aggregate without reference
to a particular Manulife Portfolio, except if the matter affects only one
portfolio or voting by portfolio is required by law, in which case shares will
be voted separately by portfolio. Maryland law does not require a registered
investment company to hold annual meetings of shareholders in any year in which
the election of directors is not required under the 1940 Act, and it is
anticipated that annual shareholder meetings will be held only when specifically
required by the 1940 Act. There are no conversion or preemptive rights in
connection with shares of MSF.
 
     NASL has an unlimited number of authorized shares of beneficial interest,
par value $.01 per share, which may be divided into series and classes thereof.
The Declaration of Trust authorizes the issuance of shares in different series,
and authorizes the NASL Board, without further shareholder action, to establish
and create additional series and to designate the rights and preferences of the
shareholders of each of the respective series. Each NASL Portfolio is one series
of NASL, and may in the future issue multiple classes of shares. Currently none
of the NASL Portfolios issues multiple classes of shares. Each share of a series
of NASL represents an equal proportionate interest in that series with each
other share of that series. The shares of each series of NASL participate
equally in the earnings, dividends and assets of the particular series.
Fractional shares have proportionate rights to full shares. Expenses of NASL
which are not attributable to a specific series are allocated to all the series
of NASL in a manner believed by management of NASL to be fair and equitable.
Generally, shares of each series will be voted separately, for example to
approve an investment advisory agreement, but shares of all series vote
together, to the extent required by the 1940 Act, including the election or
selection of trustees and independent accountants. Under Massachusetts law, NASL
is not required to hold regular annual meetings of shareholders, but may hold
special meetings from time to time. There are no conversion or preemptive rights
in connection with shares of NASL.
 
     Shareholder Voting Rights.  Each Director of MSF holds office, unless
sooner removed, until his successor is elected and qualified. Any Director may
be removed, with or without cause, by the affirmative vote of a majority of the
votes entitled to be cast on the matter at any meeting of the shareholders duly
called at which a quorum
 
                                       65
<PAGE>   75
 
is present. A quorum for MSF is a majority of the shares entitled to be voted on
a matter. A vacancy in the MSF Board resulting from the death, resignation,
removal, increase in the number of Directors or any other cause may be filled by
a vote of a majority of the remaining Directors then in office even though such
majority is less than a quorum. However, under the 1940 Act, no vacancy may be
filled by Directors unless immediately thereafter at least two-thirds of the
Directors holding office shall have been elected to such office by the
shareholders. Special meetings of shareholders, unless otherwise provided by law
or the Articles, for any purpose or purposes may be called by MSF's president or
a majority of the MSF Board, and upon the written request of the shareholders
holding at least 25% of the shares of MSF outstanding and entitled to vote at
such meeting. The By-laws of MSF permit removal of a Director by the holders of
a majority of the shares entitled to vote on the matter.
 
     Under Massachusetts law, NASL is not required to hold annual shareholder
meetings. Under the Declaration of Trust and the 1940 Act, however, shareholder
meetings are required to be called for various purposes, such as electing or
removing Trustees of NASL (although Trustees may be elected to fill vacancies or
be removed by the NASL Board without a vote of shareholders, subject to certain
restrictions in the 1940 Act), changing fundamental investment policies and
approving or disapproving an investment advisory contract. Any matters submitted
to a vote of shareholders is voted by series unless otherwise required by the
1940 Act or as determined by the NASL Board. The Declaration of Trust provides
that a meeting of shareholders shall be allowed upon the written request of the
holders of at least 25% of the outstanding shares of NASL, if shareholders of
all series are required to vote in the aggregate, or of any series if
shareholders of such series are entitled to vote by series. The Declaration of
Trust provides that 30% of the shares entitled to be voted on a matter shall
constitute a quorum. Therefore, a meeting of shareholders of NASL could take
place even if less than a majority of the shares were represented at the
meeting. Matters under the Declaration of Trust requiring approval by a majority
or greater percentage of the shares entitled to vote would not be affected by
this provision, nor would matters that under the 1940 Act require the vote of a
"majority" of the outstanding shares. Under the Declaration of Trust, each
Trustee of NASL serves until the next meeting of shareholders, if any, called
for the purpose of re-electing Trustees or electing successors to such Trustees
and until the election and qualification of his successor, or until he sooner
dies, resigns, becomes incapacitated or is removed for cause by a vote of
shareholders of NASL holding not less than two-thirds of the shares then
outstanding or by a vote of two-thirds of the Trustees then in office. The
Declaration of Trust authorizes the NASL Board to terminate NASL (or any series
thereof) by notice to the shareholders without shareholder approval. In
contrast, the dissolution of MSF is subject to shareholder approval under
applicable Maryland law.
 
     Liability of Directors and Trustees.  Under Maryland law, Directors and
officers of MSF are not liable to MSF or its stockholders for money damages,
except to the extent that (1) it is proved that such person actually received an
improper
 
                                       66
<PAGE>   76
 
benefit, or (2) a judgment or other final adjudication adverse to such person is
entered in a proceeding based on a finding that the person's action, or failure
to act, was the result of active and deliberate dishonesty and was material to
the cause of action adjudicated. However, a Director or officer of MSF is only
liable to the extent his actions are the result of willful misfeasance, bad
faith, gross negligence or reckless disregard of the duties involved in the
conduct of his office. In the event of any litigation against the directors of
officers of MSF, Maryland law permits MSF to indemnify a director or officer for
certain expenses only if he acted in good faith and reasonably believed that his
conduct was in the best interest of MSF. Maryland law permits MSF to advance
expenses to a director or officer if the facts then known do not preclude
indemnification based on the foregoing standard and on receipt of an undertaking
similar to the undertaking that would be required by NASL (as described below).
 
     Under the Declaration of Trust, the Trustees of NASL are personally liable
only for willful misfeasance, bad faith or gross negligence in the performance
of their duties or by reason of reckless disregard of their obligations and
duties as Trustees and not for errors of judgment or mistakes of fact or law.
Under the Declaration of Trust, Trustees and officers will be indemnified
against liabilities and expenses incurred in connection with the defense or
disposition of any proceeding in which they are involved by reason of their
position with NASL, except that they are not indemnified against liabilities or
expenses arising from conduct adjudicated to constitute willful misfeasance, bad
faith, gross negligence or reckless disregard of their duties. NASL may also
advance money for these expenses, provided that the Trustee or officer
undertakes to repay NASL if his conduct is later adjudicated to preclude
indemnification and certain other conditions are met.
 
     The foregoing is only a summary of certain of the major differences between
MSF, its Articles and By-Laws and Maryland law and NASL, its Declaration of
Trust and By-Laws and Massachusetts law. Shareholders may wish to refer directly
to the provisions of MSF's Articles and By-Laws, Maryland law and NASL's
Declaration of Trust and By-Laws and Massachusetts law for a more thorough
comparison.

A. EXPENSES
 
     The following expense tables are provided to assist investors in
understanding the various costs and expenses that a shareholder will indirectly
incur as an owner of shares of each of the NASL Portfolios. The table reflects
information for the twelve months ended December 31, 1995 for the NASL Money
Market Trust, restated to reflect the fee arrangements that will be in effect
commencing on the Closing Date as if these arrangements had been in effect
during that period and assuming that the Reorganization had occurred at the
beginning of that period. Because the remaining NASL Portfolios will not
commence operations until the Closing Date, information

portfolios of NASL and NASL carried on the business and operations of NASL
Series Fund, Inc. with the same investment management arrangements as were in
effect for NASL Series Fund, Inc. immediately prior to such reorganization.
 
ADVISORY ARRANGEMENTS
 
   
     NASL Financial, a Massachusetts corporation whose principal offices are
located at 116 Huntington Avenue, Boston, Massachusetts 02116, is a wholly owned
subsidiary of Security Life, the ultimate parent of which is Manulife. NASL
Financial is registered as an investment adviser under the Investment Advisers
Act of 1940 and as a broker-dealer under the Securities Exchange Act of 1934,
and it is a member of the NASD. In addition, NASL Financial serves as principal
underwriter of certain contracts issued by Security Life and as investment
adviser to one other investment company, North American Funds.
    
 
     Under the terms of the Advisory Agreement (as defined below), NASL
Financial administers the business and affairs of NASL. NASL Financial is
responsible for performing or paying for various administrative services for
NASL, including providing at NASL Financial's expense, (i) office space and all
necessary office facilities and equipment, (ii) necessary executive and other
personnel for managing the affairs of NASL and for performing certain clerical,
accounting and other office functions, and (iii) all other information and
services, other than services of counsel, independent accountants or investment
subadvisory services provided by any subadviser under a subadvisory agreement,
required in connection with the preparation of all tax returns and documents
required to comply with the federal securities laws. NASL Financial pays the
cost of (i) any advertising or sales literature relating solely to NASL, (ii)
the cost of printing and mailing prospectuses to persons other than current
holders of NASL shares or of variable contracts funded by NASL shares and (iii)
the compensation of NASL's officers and Trustees that are officers, directors or
employees of NASL Financial or its affiliates. In addition, advisory fees are
reduced or NASL Financial reimburses NASL if the total of all expenses
(excluding advisory fees, taxes, portfolio brokerage commissions, interest,
litigation and indemnification expenses and other extraordinary expenses not
incurred in the ordinary course of NASL's business) applicable to a NASL
Portfolio exceeds an annual rate of .75% in the case of the NASL International
Stock Trust and NASL Pacific Rim Emerging Markets Trust, .15% in the case of the
NASL Equity Index Trust or .50% in the case of all other NASL Portfolios of the
average annual net assets of such NASL Portfolio. The expense limitations will
continue in effect from year to year unless otherwise terminated at any year end
by NASL Financial on 30 days' notice to NASL. For the prior fiscal year, NASL
Financial did not reimburse NASL for any expenses since expenses
 
                                       76
<PAGE>   86
 
were below the expense limitations. However, if expenses were to increase above
the expense limits and the reimbursements were terminated, NASL expenses would
increase.
 
     In addition to providing the services and expense limitations described
above, NASL Financial selects, contracts with and compensates subadvisers to
manage the investment and reinvestment of the assets of the NASL Portfolios.
NASL Financial does not manage any of the NASL Portfolios' assets on a
day-to-day basis. NASL Financial monitors the compliance of such subadvisers
with the investment objectives and related policies of each NASL Portfolio and
reviews the performance of such subadvisers and reports periodically on such
performance to the NASL Board. Agreements with NASL's subadvisers have
heretofore been approved by the vote of a majority of the then outstanding
shares of the portfolios of NASL to be managed by the subadviser. NASL has filed
an application with the Commission seeking exemptive relief to permit the
appointment of a subadviser pursuant to an agreement that is not approved by
shareholders, and has submitted to shareholders of record of the portfolios of
NASL as of October 23, 1996 a proposal to authorize NASL to make such subadviser
appointments in the future (the "manager of managers" proposal). If such
exemptive relief is granted and such shareholder approval is obtained, NASL
would be able to change subadvisers from time to time without the expense and
delays associated with obtaining shareholder approval of the new subadviser.
There is no assurance that the requested relief will be granted or shareholder
approval obtained.
 
     As compensation for its services, NASL Financial receives a fee from NASL
computed separately for each NASL Portfolio. The fee for each NASL Portfolio is
stated as an annual percentage of the current value of the net assets of the
NASL Portfolio. The fee, which is accrued daily and payable monthly, is
calculated for each day by multiplying the daily equivalent of the annual
percentage prescribed for a NASL Portfolio by the value of the net assets of the
NASL Portfolio at the close of business on the previous business day of NASL.
The following is a schedule of the management fees each NASL Portfolio is
contractually obligated to pay NASL Financial:

paid by most funds to their advisers, but are not higher than the fees paid by
many funds with similar investment objectives and policies.
 
     For the year ended December 31, 1995 the aggregate investment advisory fees
paid by NASL was $33,808,255. Of that amount, $1,318,573 was paid with respect
to the NASL Money Market Trust, with the balance paid with respect to the other
portfolios of NASL that were in existence during the year ended December 31,
1995.

counselling firm which provides investment services to investment companies,
employee benefit plans, endowment funds, foundations and other institutions and

Growth Trust since 1990. He is a managing director of EMW and has been with
Warburg Pincus since 1987.
 
  Founders
 
     Investment decisions for the NASL Balanced Trust are made by its
subadviser, Founders, located at 2930 East Third Avenue, Denver, Colorado 80206,
a registered investment adviser first established as an asset manager in 1938.
Bjorn K. Borgen, Chairman, Chief Executive Officer and Chief Investment Officer
of Founders, owns 100% of the voting stock of Founders. Founders also is
subadviser to the NASL Growth Trust, NASL International Small Cap Trust, and
NASL Worldwide Growth Trust.
 
     Founders is a "growth-style" manager of equity portfolios and gives
priority to the selection of individual securities that have the potential to
provide superior results over time, despite short-term volatility. Under normal
circumstances, Founders' approach to investment management gives greater
emphasis to the fundamental financial, marketing and operating strengths of the
companies whose securities it buys, and is less concerned with the short-term
impact of changes in macroeconomic and market conditions. Founders focuses on
purchasing the stocks of companies with strong management and market positions
that have earnings prospects that are significantly above the average for their
market sectors.
 
     To facilitate the day-to-day investment management of the NASL Balanced
Trust, Founders will employ a unique team-and-lead-manager system. The
management team will be composed of several members of the Investment
Department, including Founders' Chief Investment Officer, lead portfolio
managers, assistant portfolio managers, portfolio traders and research analysts.
Team members will share responsibility for providing ideas, information,
knowledge and expertise in the management of the portfolios. Each team member
has one or more areas of expertise that will be applied to the management of the
NASL Balanced Trust. Daily decisions on portfolio selection for the NASL
Balanced Test will rest with a lead portfolio manager assigned to the NASL
Balanced Trust.
 
     Brian F. Kelly, Portfolio Manager, will be the lead portfolio manager for
the Balanced Trust. Mr. Kelly joined Founders in 1996. Prior to joining
Founders, Mr. Kelly served as portfolio manager for Invesco Trust Company
(1993-1996) and as a senior investment analyst for Sears Investment Management
Company (1986-1993). A graduate of the University of Notre Dame, Mr. Kelly
received his MBA and JD from the University of Iowa. He is also a Certified
Public Accountant.
 
     Under the terms of each of the Subadvisory Agreements (as defined below),
the subadviser manages the investment and reinvestment of the assets of the
assigned NASL Portfolios, subject to the supervision of the NASL Board. The
subadviser formulates a continuous investment program for each such NASL
Portfolio consistent with its investment objectives and policies outlined in
this Prospectus/Proxy Statement. Each subadviser implements such programs by
 
                                       81
<PAGE>   91
 
purchases and sales of securities and regularly reports to NASL Financial and
the NASL Board with respect to the implementation of such programs.
 
     As compensation for their services, the subadvisers receive fees from NASL
Financial computed separately for each NASL Portfolio. The fee for each NASL
Portfolio is stated as an annual percentage of the current value of the net
assets of such NASL Portfolio. The fees are calculated on the basis of the
average of all valuations of net assets of each NASL Portfolio made at the close
of business on each business day of NASL during the period for which such fees
are paid. Once the average net assets of a NASL Portfolio exceed specified
amounts, the fee is reduced with respect to such excess. The following is a
schedule of the management fees NASL Financial currently is obligated to pay the
subadvisers out of the advisory fee it receives from each NASL Portfolio as
specified above:

* With respect to this NASL Portfolio, the applicable subadvisory fee is .75% on
  the first $20,000,000 and .60% between $20,000,000 and $50,000,000.
 
     For the year ended December 31, 1995, NASL Financial paid aggregate
subadvisory fees of $12,007,940. Of that amount, $197,786 was paid with respect
to the NASL Money Market Trust (such amount was paid to such NASL Portfolio's
previous subadviser), with the balance paid with respect to the other portfolios
of NASL that were in existence during the year ended December 31, 1995.
 
     Above are brief summaries of the advisory agreement with NASL Financial
("Advisory Agreement") and the subadvisory agreements with the subadvisers
("Subadvisory Agreements"). A more comprehensive statement of the terms of such
agreements appears in the Statement of Additional Information under the caption
"Investment Management Arrangements".

     All or a portion of NASL brokerage commissions may be paid to affiliates of
Price-Fleming and the subadvisers to the other portfolios of NASL.
    
 
EXPENSES
 
     Subject to the expense limitations discussed above, NASL is responsible for
the payment of all expenses of its organization, operations and business, except
for those expenses NASL Financial or the NASL subadvisers have agreed to pay
pursuant to the Advisory or Subadvisory Agreements. Among the expenses to be
borne by NASL are charges and expenses of the custodian, independent accountants
and transfer, bookkeeping and dividend disbursing agents appointed by NASL,
brokers' commissions and issue and transfer taxes on securities transactions to
which NASL is a party, taxes payable by NASL, and legal fees and expenses in
connection with the affairs of NASL, including registering and qualifying its
shares with regulatory authorities and in connection with any litigation.
 
     For the year ended December 31, 1995, the expenses, including NASL
Financial's fee but excluding portfolio brokerage commissions, expressed as a
percentage of average net assets, were .54% for the NASL Money Market Trust.
 
     For the year ended December 31, 1995, the expenses, excluding NASL
Financial's fee and portfolio brokerage commissions, expressed as a percentage
of average net assets, .04% for the NASL Money Market Trust.
 
     Each of the NASL Portfolios anticipates that its annual portfolio turnover
rate will exceed 100%. A high portfolio turnover rate generally involves
correspondingly greater brokerage commission expenses, which must be borne
directly by the NASL Portfolio. The portfolio turnover rate of each of the NASL
Portfolios may vary from year to year, as well as within a year. See "Portfolio
Turnover" in the Statement of Additional Information.
 
PERFORMANCE DATA
 
   
     From time to time NASL may publish advertisements containing performance
data relating to the NASL Portfolios. Performance data will consist of total
return quotations which will always include quotations for recent one-year and,
when applicable, five-year and ten-year periods and where less than five or ten
years, for the period since the date the NASL Portfolio (including, in the case
of the NASL Money Market Trust, its predecessor prior to the reorganization of
NASL on December 31, 1988) became available for investment. In the case of the
NASL Pacific Rim Emerging Markets Trust, NASL Real Estate Securities Trust, NASL
Common Stock Trust, NASL Capital Growth Bond Trust and NASL Equity Index Trust,
such quotations will be for periods that include the performance of the
corresponding Manulife Portfolios. Such quotations for such periods will be the
average annual rates of return required for an initial investment of $1,000 to
equal the market value of such investment on the last day of the period, after
reflection of all NASL charges and expenses and assuming reinvestment of all
dividends and
    
 
                                       83
<PAGE>   93
   
distributions. Performance figures used by NASL are based on the actual
historical performance of its portfolios for specified periods, and the figures
are not intended to indicate future performance. Moreover, NASL's performance
figures are not comparable to those for public mutual funds. Trust shares are
only available as the underlying investment medium for contracts which provide
for certain charges, as described in the prospectus offering such contracts. The
impact of such charges is not reflected in NASL's performance figures. More
detailed information on the computations is set forth in the Statement of
Additional Information. NASL's annual report, which is available without charge
upon request, contains further discussions of NASL performance.
    
 
     NASL may also from time to time advertise the performance of certain NASL
Portfolios relative to that of unmanaged indices, including but not limited to
the Dow Jones Industrial Average, the Lehman Brothers Bond, Government
Corporate, Corporate and Aggregate Indices, the Standard and Poor's 500, the
Value Line Composite and the Morgan Stanley Capital International Europe,
Australia and Far East ("EAFE") and World Indices. NASL may also advertise the
performance rankings assigned certain portfolios or their investment subadvisers
by various statistical services, including but not limited to SEI, Lipper
Analytical Services, Inc.'s Mutual Fund Performance Analysis and Variable
Insurance Products Performance Analysis, Variable Annuity Research and Data
Service, Interesec Research Survey of Non-U.S. Equity Fund Returns and Frank
Russell International Universe, and any other data which may be presented from
time to time by such analysts as Dow Jones, Morning Star, Chase International
Performance, Wilson Associates, Stranger, CDA Investment Technology, the
Consumer Price Index ("CPI"), The Bank Rate Monitor National Index,
IBC/Donaghue's Average U.S. Government and Agency, or as they appear in various
publications, including The Wall Street Journal, The New York Times, Forbes,
Barrons, Fortune, Money Magazine, Financial World and Financial Services Week.
 
D. PURCHASE AND REDEMPTION OF SHARES
 
     Like MSF, shares of NASL are offered continuously, without sales charge, at
prices equal to the respective net asset values of the portfolio being
purchased. Both MSF and NASL sell their shares directly without the use of any
underwriter. Shares of NASL are sold and redeemed at their net asset value next
computed after a purchase payment or redemption request is received by the
shareholder from the contract owner or after any other purchase or redemption
order is received by NASL. Depending upon the net asset values at that time, the
amount paid upon redemption may be more or less than the cost of the shares
redeemed. Payment for shares redeemed will be made as soon as possible, but in
any event within seven days after receipt of a request for redemption.
 
     The net asset value of the shares of each NASL Portfolio is determined once
daily as of the close of regularly scheduled trading on the New York Stock
Exchange, Monday through Friday, except that no determination is required on

(i) days on which changes in the value of such NASL Portfolio's portfolio
securities will not materially affect the current net asset value of the shares
of the NASL Portfolio, (ii) days during which no shares of such NASL Portfolio
are tendered for redemption and no order to purchase or sell such shares is
received by NASL, or (iii) the following business holidays or the days on which
such holidays are observed by the New York Stock 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 of the New York Stock Exchange. The values of such
securities used in computing the net asset value of a NASL Portfolio's shares
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 the New York Stock Exchange and would
therefore not be reflected in the computation of a NASL Portfolio'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 NASL subadvisers under procedures established
and regularly reviewed by the NASL Board.
 
     The net asset values per share of all NASL Portfolios other than the NASL
Money Market Trust are computed by adding the sum of the value of the securities
held by each NASL Portfolio plus any cash or other assets it holds, subtracting
all its liabilities, and dividing the result by the total number of shares
outstanding of that NASL Portfolio at such time. Securities held by each of the
NASL Portfolios other than the NASL Money Market Trust, except for money market
instruments with remaining maturities of 60 days or less, are valued at their
market value if market quotations are readily available. Otherwise, such
securities are valued at fair value as determined in good faith by the NASL
Board although the actual calculations may be made by persons acting pursuant to
the direction of the NASL Board.
 
     All instruments held by the NASL Money Market Trust and money market
instruments with a remaining maturity of 60 days or less held by the other NASL
Portfolios are valued on an amortized cost basis.
 
E. TAX MATTERS
 
     Tax Status.  NASL believes that each NASL Portfolio will qualify as a
regulated investment company under Subchapter M, Chapter 1, Subtitle A of the
Code, and NASL intends to take the steps necessary to so qualify each NASL
Portfolio. As a result of qualifying as a regulated investment company, each
NASL Portfolio will not be subject to federal income tax to the extent that the
NASL Portfolio distributes its net income, including its net realized capital
gains, to its shareholders. Accordingly, each NASL Portfolio intends to
distribute substantially all of its net income, including all of its net
realized capital gains, to its shareholders.
 
                                       85
<PAGE>   95
 
Under current law, net income, including net realized capital gain, is not taxed
to a life insurance company to the extent that it is applied to increase the
reserves for the company's variable annuity and life insurance contracts.
 
     Sources of Gross Income.  To qualify for treatment as a regulated
investment company, a NASL Portfolio must, among other things, derive its income
from certain sources. Specifically, in each taxable year a NASL Portfolio must
derive at least 90% of its gross income from dividends, interest, payments with
respect to securities loans, gains from the sale or other disposition of stock,
securities or foreign currencies, or other income (including, but not limited
to, gains from options, futures or forward contracts) derived with respect to
its business of investing in stock, securities, or currencies. A NASL Portfolio
must also derive less than 30% of its gross income from the sale or other
disposition of any of the following which was held for less than three months:
(1) stock or securities, (2) options, futures, or forward contracts (other than
options, futures, or forward contracts on foreign currencies), or (3) foreign
currencies (or options, futures, or forward contracts on foreign currencies) but
only if such currencies (or options, futures, or forward contracts) are not
directly related to the NASL Portfolio's principal business of investing in
stock or securities (or options and futures with respect to stocks or
securities). For purposes of these tests, gross income generally is determined
without regard to losses from the sale or other disposition of stock or
securities or other portfolio assets. Compliance with these requirements may
prevent a NASL Portfolio from utilizing options, futures, and forward contracts
as much as the subadviser might otherwise believe to be desirable.
 
     Diversification of Assets.  To qualify for treatment as a regulated
investment company, a NASL Portfolio must also satisfy certain requirements with
respect to the diversification of its assets. A NASL Portfolio must have, at the
close of each quarter of the taxable year, at least 50% of the value of its
total assets represented by cash, cash items, United States Government
securities, securities of other regulated investment companies, and other
securities which, in respect of any one issuer, do not represent more than 5% of
the value of the assets of the NASL Portfolio nor more than 10% of the voting
securities of that issuer. In addition, at those times not more than 25% of the
value of the NASL Portfolio's assets may be invested in securities (other than
United States Government securities or the securities of other regulated
investment companies) of any one issuer, or of two or more issuers which the
NASL Portfolio controls and which are engaged in the same or similar trades or
businesses or related trades or businesses.
 
     Because NASL is established as an investment medium for insurance company
separate accounts, regulations under Subchapter L of the Code impose additional
diversification requirements on each NASL Portfolio. These requirements
generally are that no more than 55% of the value of the assets of a NASL
Portfolio may be represented by any one investment; no more than 70% by any two
investments; no more than 80% by any three investments; and no more than 90% by
any four investments. For these purposes, all securities of the same issuer are
treated as a
 
                                       86
<PAGE>   96
 
single investment and each United States government agency or instrumentality is
treated as a separate issuer.
 
     Foreign Investments.  NASL Portfolios 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 at a rate between 10% and 35%. The investment yield of any NASL
Portfolio that invests in foreign securities or currencies will be reduced by
these foreign taxes. Shareholders will bear the cost of any foreign tax
withholding, but may not be able to claim a foreign tax credit or deduction for
these foreign taxes. NASL Portfolios investing in securities of passive foreign
investment companies may be subject to U.S. federal income taxes and interest
charges (and investment yield of the NASL Portfolios making such investments
will be reduced by these taxes and interest charges). Shareholders will bear the
cost of these taxes and interest charges, but will not be able to claim a
deduction for these amounts.
 
     Additional Tax Considerations.  If a NASL Portfolio failed to qualify as a
regulated investment company, owners of contracts based on such NASL Portfolio
(1) might be taxed currently on the investment earnings under their contracts
and thereby lose the benefit of tax deferral, and (2) such NASL Portfolio might
incur additional taxes. In addition, if a NASL Portfolio failed to comply with
the diversification requirements of the regulations under Subchapter L of the
Code, owners of contracts based on such NASL Portfolio would be taxed on the
investment earnings under their contracts and thereby lose the benefit of tax
deferral. Accordingly, compliance with the above rules is carefully monitored by
NASL Financial and the NASL subadvisers and it is intended that the NASL
Portfolios will comply with these rules as they exist or as they may be modified
from time to time. Compliance with the tax requirements described above may
result in a reduction in the return under a NASL Portfolio, since, to comply
with the above rules, the investments utilized (and the time at which such
investments are entered into and closed out) may be different from those that
the NASL subadvisers might otherwise believe to be desirable.
 
     Other Information.  For more information regarding the tax implications for
the purchaser of a variable annuity or life insurance contract who allocates
investments to NASL, please refer to the prospectus for such contract.
 
     The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury Regulations currently in effect. It is not
intended to be a complete explanation or a substitute for consultation with
individual tax advisers. For the complete provisions, reference should be made
to the pertinent Code sections and the Treasury Regulations promulgated
thereunder. The Code and Regulations are subject to change.

F. OTHER INFORMATION CONCERNING SHARES OF NASL
 
DIVIDENDS
 
     NASL intends to declare as dividends substantially all of the net
investment income, if any, of each NASL Portfolio. For dividend purposes, net
investment income of each NASL Portfolio except the NASL Money Market Trust will
consist of all payments of dividends (other than stock dividends) or interest
received by such NASL Portfolio less the estimated expenses of such NASL
Portfolio (including fees payable to NASL Financial) and for the NASL Money
Market Trust it will consist of the interest income earned on investments, plus
or minus amortized purchase discount or premium, plus or minus realized gains
and losses, less estimated expenses. Dividends from the net investment income
and the net realized short-term and long-term capital gains, if any, for each
NASL Portfolio except the NASL Money Market Trust will be declared not less
frequently than annually and reinvested in additional full and fractional shares
of that NASL Portfolio or paid in cash. Dividends from net investment income and
net realized short-term and long-term capital gains, if any, for the NASL Money
Market Trust will be declared and reinvested, or paid in cash, daily.
 
SHARES OF NASL
 
     NASL's Declaration of Trust authorizes the NASL Board to issue an unlimited
number of full and fractional shares of beneficial interest having a par value
of $.01 per share, to divide such shares into an unlimited number of series of
shares and to designate the relative rights and preferences thereof, all without
shareholder approval. In addition, the NASL Board is authorized to divide any
series of shares into separate classes, also without shareholder approval. NASL
currently has seventeen series of shares, one for each portfolio of NASL. Shares
of each NASL Portfolio have equal rights with regard to redemptions, dividends,
distributions and liquidations with respect to that NASL Portfolio. When issued,
shares are fully paid and non-assessable and do not have preemptive or
conversion rights or cumulative voting rights. All shares are entitled to one
vote and are voted by series, except that when voting for the election of the
NASL Board and when otherwise permitted by the 1940 Act, shares are voted in the
aggregate. Only shares of a particular NASL Portfolio are entitled to vote on
matters determined by the NASL Board to affect only the interests of that NASL
Portfolio.
 
     NASL currently has three shareholders, Security Life, Manufacturers Life of
America and FNAL. Security Life provided NASL with its initial capital.
Currently, Security Life owns NASL shares attributable to the initial
capitalization of the NASL Growth and Income Trust. Each shareholder owns the
NASL shares attributable to contracts participating in its separate accounts and
will vote such shares and, in the case of Security Life, NASL shares owned
beneficially by Security Life, in accordance with instructions received from
contract owners.
 
                                       88
<PAGE>   98
 
     Shares of NASL may be sold to both variable annuity separate accounts and
variable life insurance separate accounts of affiliated insurance companies.
NASL currently does not foresee any disadvantages to the owners of variable
annuity or variable life insurance contracts arising from the fact that the
interests of those owners may differ. Nevertheless, the NASL Board will monitor
events in order to identify any material irreconcilable conflicts which may
possibly arise due to differences of tax treatment or other considerations and
to determine what action, if any, should be taken in response thereto. Such an
action could include the withdrawal of a separate account from participation in
NASL.

                             DEBT SECURITY RATINGS
 
STANDARD & POOR'S RATINGS GROUP ("S&P")
 
<TABLE>
<S>           <C>
Commercial Paper:
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")
 
<TABLE>
<S>           <C>
Commercial Paper:
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.
Bonds:
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.

<PAGE>   103
 
<TABLE>
<S>           <C>
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 charac-
              teristics 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.

     The International Stock Trust, Emerging Growth Trust, Balanced Trust,

Trust, Capital Growth Bond Trust and Equity Index Trust of the Trust are also

     WHEREAS, the Board of Directors of the Fund and the Board of Trustees of
the Trust have determined, respectively, that the transfer of all of the assets
and liabilities of each Manulife Portfolio to the corresponding NASL Portfolio
noted above is in the best interests of each Manulife Portfolio and the
corresponding NASL Portfolio, as well as the best interests of shareholders and
holders of variable life and annuity contracts funded by shares of the Manulife
Portfolios and the NASL Portfolios, and that the interests of existing
shareholders and contractholders would not be diluted as a result of this
transaction;
 
     WHEREAS, the parties hereto intend to provide for the reorganization of the
Manulife Portfolios (the "Reorganization") through the acquisition by the Trust
on behalf of the NASL Portfolios of all of the assets, subject to all of the
liabilities, of the Manulife Portfolios in exchange for shares of beneficial
interest, par value $.01 per share, of the NASL Portfolios (the "NASL Portfolio
Shares"), the liquidation of the Manulife Portfolios and the distribution to
Fund shareholders of such NASL Portfolio Shares, all pursuant to the provisions
of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code");
 
                                       1
<PAGE>   106
 
     NOW, THEREFORE, in consideration of the mutual promises herein contained,
the parties hereto agree as follows:
 
 1. TRANSFER OF ASSETS OF THE MANULIFE PORTFOLIOS IN EXCHANGE FOR THE NASL
    PORTFOLIO SHARES AND LIQUIDATION OF THE MANULIFE PORTFOLIOS
 
     (a) Plan of Reorganization.
 
         (i) The Fund on behalf of each Manulife Portfolio will convey, transfer
     and deliver the assets of each Manulife Portfolio to the NASL Portfolio set
     forth opposite its name in the table above (each such NASL Portfolio being
     the "Corresponding NASL Portfolio" of the Manulife Portfolio set forth
     opposite its name, and each such Manulife Portfolio being the
     "Corresponding Manulife Portfolio" of the NASL Portfolio set forth opposite
     its name) all of the then existing assets of such Manulife Portfolio
     (consisting, without limitation, of portfolio securities and instruments,
     dividend and interest receivables, cash and other assets). In consideration
     thereof, the Trust on behalf of each NASL Portfolio will (A) assume and
     pay, to the extent that they exist on or after the Effective Time of the
     Reorganization (as defined in Section 1(b)(i) hereof), all of the
     obligations and liabilities of the Corresponding Manulife Portfolio and (B)
     issue and deliver to the Corresponding Manulife Portfolio full and
     fractional shares of beneficial interest of the Corresponding NASL
     Portfolio, with respect to each Corresponding NASL Portfolio equal to that
     number of full and fractional NASL Portfolio Shares as determined in
     Section 1(c) hereof. Any shares of capital stock (if any), par value $.01
     per share, of the Manulife Portfolios ("Manulife Portfolio Shares") held in
     the treasury of the Fund at the Effective Time of the Reorganization shall
     thereupon be retired. Such transactions shall take place at the closing
     provided for in Section 1(b) hereof (the "Closing"). All computations for
     the Manulife Portfolios and the NASL Portfolios shall be performed by State
     Street Bank and Trust Company (the "Custodian"), as custodian and pricing
     agent for the Manulife Portfolios and the NASL Portfolios. The
     determination of said Custodian shall be conclusive and binding on all
     parties in interest.
 
          (ii) As of the Effective Time of the Reorganization, each Manulife
     Portfolio will liquidate and distribute pro rata to its shareholders of
     record ("Manulife Portfolio shareholders") as of the Effective Time of the
     Reorganization the NASL Portfolio Shares received by such Manulife
     Portfolio pursuant to Section 1(a)(i) in actual or constructive exchange
     for the shares of the Manulife Portfolio held by the Manulife Portfolio
     shareholders. Such liquidation and distribution will be accomplished by the
     transfer of the Corresponding NASL Portfolio Shares then credited to the
     account of each Manulife Portfolio on the books of the Corresponding NASL
     Portfolio, to open accounts on the share records of the Corresponding NASL
     Portfolio in the names of the Manulife Portfolio shareholders and
     representing the respective pro rata
 
                                      2
<PAGE>   107
 
     number of the NASL Portfolio Shares due such shareholders. The NASL
     Portfolios will not issue certificates representing the NASL Portfolio
     Shares in connection with such exchange.
 
          (iii) As soon as practicable after the Effective Time of the
     Reorganization, the Fund shall take all the necessary steps under Maryland
     law and the Fund's Articles of Incorporation to effect a complete
     dissolution of the Fund and to deregister the Fund under the Investment
     Company Act of 1940, as amended (the "Act").
 
     (b) Closing and Effective Time of the Reorganization.
 
          (i) Subject to the satisfaction of the conditions to the Closing
     specified in this Agreement, the Closing shall occur as of the close of
     regularly scheduled trading on the New York Stock Exchange (the "Effective
     Time of the Reorganization") on the day (the "Closing Date") which is the
     later of (A) the final adjournment of the meeting of the holders of Fund
     shares at which this Agreement will be considered, (B) the declaration by
     the Securities and Exchange Commission (the "Commission") of the
     effectiveness of the N-1A Amendment (as defined in Section 4(b) hereof),
     (C) December 31, 1996 and (D) such later day as the parties may mutually
     agree.
 
          (ii) The Closing shall be held at the offices of the Trust in Boston,
     Massachusetts or at such other place as the parties may agree. All acts
     taking place at the Closing shall be deemed to take place simultaneously as
     of the Effective Time of the Reorganization unless otherwise provided.
 
          (iii) In the event that on the proposed Closing Date (A) the New York
     Stock Exchange shall be closed to trading or trading thereon shall be
     restricted, or (B) trading or the reporting of trading on said Exchange or
     elsewhere shall be disrupted so that accurate valuation of the net assets
     of the NASL Portfolios or the Manulife Portfolios is impracticable, the
     Closing Date shall be postponed until the first business day after the day
     when trading shall have been fully resumed and reporting shall have been
     restored.
 
          (iv) At the Closing, portfolio securities of the Manulife Portfolios
     shall be transferred by the Custodian to the accounts of the Corresponding
     NASL Portfolios duly endorsed in proper form for transfer, in such
     condition as to constitute good delivery thereof in accordance with the
     custom of brokers, and shall be accompanied by all necessary federal and
     state stock transfer stamps or a check for the appropriate purchase price
     thereof.
 
     (c) Valuation.
 
          (i) The net asset value of the shares of each NASL Portfolio and the
     net value of the assets of each Corresponding Manulife Portfolio to be
     transferred in exchange therefore shall be determined as of the Effective
     Time of the Reorganization. The net asset value of the NASL Portfolio
     Shares shall be computed by the Custodian in the manner set forth in the
     Trust's Declaration
 
                                        3
<PAGE>   108
 
     of Trust or By-laws and then current prospectus and statement of additional
     information and shall be computed to not less than two decimal places. The
     net value of the assets of each Manulife Portfolio to be transferred shall
     be computed by the Custodian by calculating the value of the assets
     transferred by the Manulife Portfolio and by subtracting therefrom the
     amount of the liabilities assigned and transferred to the Corresponding
     NASL Portfolio, said assets and liabilities to be valued in the manner set
     forth in the Fund's Articles of Incorporation or By-laws and then current
     prospectus and statement of additional information.
 
          (ii) The number of NASL Portfolio Shares to be issued (including
     fractional shares, if any) by each NASL Portfolio in exchange for the
     Corresponding Manulife Portfolio's assets shall be determined by an
     exchange ratio computed by dividing the net value of such Manulife
     Portfolio's assets by the net asset value per share of such NASL Portfolio,
     both as determined in accordance with Section 1(c)(i); provided, however,
     that in the case of the Manulife Portfolios which correspond to the New
     NASL Portfolios, the exchange ratio shall be one.
 
          (iii) All computations of value shall be made by the Custodian in
     accordance with its regular practice as pricing agent for the NASL
     Portfolios and the Manulife Portfolios.
 
 2. REPRESENTATIONS AND WARRANTIES OF NASL
 
     The Trust represents and warrants to the Fund as follows:
 
          (a) Organization, Existence, etc. The Trust is a business trust duly
     organized, validly existing and in good standing under the laws of the
     Commonwealth of Massachusetts and has the power to carry on its business as
     it is now being conducted, and each NASL Portfolio is a validly existing
     series of shares of such business trust representing interests therein
     under the laws of Massachusetts. The Trust has all necessary federal, state
     and local authorization to own all of its properties and assets and to
     carry on its business as now being conducted.
 
          (b) Registration as Investment Company. The Trust is registered under
     the Act as an open-end investment company of the management type; such
     registration has not been revoked or rescinded and is in full force and
     effect.
 
          (c) Current Offering Documents. The current prospectus and statement
     of additional information of the Trust, each dated July 11, 1996, as
     supplemented in the case of the prospectus by a supplement dated July 31,
     1996 and in the case of the statement of additional information by a
     supplement dated July 24, 1996, and (except in the case of such
     supplements) included in the Trust's registration statement on Form N-1A
     filed with the Commission, comply in all material respects with the
     requirements of the Securities Act of 1933, as amended (the "Securities
     Act") and the Act and do not contain an
 
                                        4
<PAGE>   109
 
     untrue statement of a material fact or omit to state a material fact
     necessary to make the statements therein, in light of the circumstances
     under which they were made, not misleading.
 
          (d) Capitalization. The Trust has an unlimited number of authorized
     shares of beneficial interest, par value $.01 per share, of which as of
     June 24, 1996 there were outstanding the following numbers of shares of the
     NASL Portfolios: 33,815,940.278 shares of Money Market Trust, and no shares
     of such NASL Portfolio were held in the treasury of the Trust. There are no
     outstanding shares of the New NASL Portfolios. All of the outstanding
     shares of the Trust have been duly authorized and are validly issued, fully
     paid and nonassessable (except as disclosed in the Trust's prospectus and
     recognizing that under Massachusetts law, shareholders of an NASL Portfolio
     could, under certain circumstances, be held personally liable for the
     obligations of such NASL Portfolio). Because the Trust is an open-end
     investment company engaged in the continuous offering and redemption of its
     shares, the number of outstanding shares may change prior to the Effective
     Time of the Reorganization. All of the issued and outstanding shares of
     Money Market Trust have been offered and sold in compliance in all material
     respects with applicable registration requirements of the Securities Act
     and applicable state securities laws.
 
          (e) Financial Statements. The financial statements of the Trust for
     the fiscal year ended December 31, 1995, which have been audited by Coopers
     & Lybrand L.L.P., and the unaudited financial statements of the Trust for
     the six months ended June 30, 1996 (collectively, the "Trust's Financial
     Statements"), previously delivered to the Fund, fairly present the
     financial position of the Trust as of the dates thereof and the results of
     its operations and changes in its net assets for each of the periods
     indicated in accordance with generally accepted accounting principles
     ("GAAP").
 
          (f) Shares to be Issued Upon Reorganization. The NASL Portfolio Shares
     to be issued in connection with the Reorganization will be duly authorized
     and upon consummation of the Reorganization will be validly issued, fully
     paid and nonassessable (except as disclosed in the Trust's prospectus and
     recognizing that under Massachusetts law, shareholders of an NASL Portfolio
     could, under certain circumstances, be held personally liable for the
     obligations of such NASL Portfolio).
 
          (g) Authority Relative to this Agreement. The Trust has the power to
     enter into this Agreement and to carry out its obligations hereunder. The
     execution and delivery of this Agreement and the consummation of the
     transactions contemplated hereby have been duly authorized by the Trust's
     Board of Trustees and no other proceedings by the Trust other than those
     contemplated under this Agreement are necessary to authorize its officers
     to effectuate this Agreement and the transactions contemplated hereby. The
     Trust is not a party to or obligated under any provision of its declaration
     of trust
 
                                        5

     or by-laws, or under any indenture or contract provision or any other
     commitment or obligation, or subject to any order or decree, which would be
     violated by or which would prevent its execution and performance of this
     Agreement in accordance with its terms.
 
          (h) Liabilities. There are no liabilities of the Trust or the NASL
     Portfolios, whether actual or contingent and whether or not determined or
     determinable, other than liabilities disclosed or provided for in the
     Trust's Financial Statements and liabilities incurred in the ordinary
     course of business subsequent to June 30, 1996 or otherwise previously
     disclosed to the Fund, none of which has been materially adverse to the
     business, assets or results of operations of the Trust.
 
          (i) No Material Adverse Change. Since June 30, 1996, there has been no
     material adverse change in the financial condition, results of operations,
     business, properties or assets of the Trust, other than those occurring in
     the ordinary course of business (for these purposes, a decline in net asset
     value and a decline in net assets due to redemptions do not constitute a
     material adverse change).
 
          (j) Litigation. There are no claims, actions, suits or proceedings
     pending or, to the knowledge of the Trust, threatened which would adversely
     affect the Trust or the NASL Portfolios or the Trust's assets or business
     or which would prevent or hinder consummation of the transactions
     contemplated hereby, there are no facts which would form the basis for the
     institution of administrative proceedings against the Trust and, to the
     knowledge of the Trust, there are no regulatory investigations of the Trust
     pending or threatened, other than routine inspections and audits.
 
          (k) Contracts. No default exists under any material contract or other
     commitment to which the Trust or any NASL Portfolio is subject. As of the
     Effective Time of the Reorganization, the Trust will have no liability in
     respect of any of the contracts referred to in Section 4(f).
 
          (l) Taxes. The federal income tax returns of the Trust and each series
     of the Trust, and all other income tax returns required to be filed by the
     Trust and any series of the Trust, have been filed for all taxable years to
     and including December 31, 1995, and all taxes payable pursuant to such
     returns have been paid. To the knowledge of the Trust, no such return is
     under audit and no assessment has been asserted in respect of any such
     return. All federal and other taxes owed by the Trust or any series of the
     Trust have been paid so far as due. Each series of the Trust, other than
     the New NASL Portfolios, Science & Technology Trust, Equity-Income Trust,
     High Yield Trust, Worldwide Growth Trust and Pilgrim Baxter Growth Trust,
     which have not yet commenced operations, is qualified as a regulated
     investment company under the Code in respect of each taxable year since
     commencement of its operations, and each New NASL Portfolio will elect to
     be treated as a regulated
 
                                        6
<PAGE>   111
 
     investment company under the Code. The Trust and each NASL Portfolio
     currently are, and will continue to be up until and at the Closing Date, in

     Amendment (as defined in Section 4(b) hereof) and the approvals of Trust
     shareholders referred to in Sections 6(f) and 6(g) hereof, no consents,
     approvals, authorizations, registrations or exemptions under federal or
     state laws are necessary for the consummation by the Trust of the
     Reorganization, except such as have been obtained as of the date hereof.
 
 3. REPRESENTATIONS AND WARRANTIES OF THE FUND
 
     The Fund represents and warrants to the Trust as follows:
 
          (a) Organization, Existence, etc. The Fund is a corporation duly
     organized, validly existing and in good standing under the laws of the
     State of Maryland and has the power to carry on its business as it is now
     being conducted, and each Manulife Portfolio is a validly existing series
     of shares of such corporation representing interests therein under the laws
     of Maryland. The Fund has all necessary federal, state and local
     authorization to own all of its properties and assets and to carry on its
     business as now being conducted.
 
          (b) Registration as Investment Company. The Fund is registered under
     the Act as an open-end investment company of the management type; such
     registration has not been revoked or rescinded and is in full force and

     of additional information of the Fund, each dated August 14, 1996 and

     of 1,000,000,000 shares of common stock, par value $.01 per share, of which

     were held in the treasury of the Fund. All of the outstanding shares of the
     Fund have been duly authorized and are validly issued, fully paid and
     nonassessable. Because the Fund is an open-end investment company engaged
     in the continuous offering and redemption of its shares, the number of

     set forth in any list of shareholders of record provided to the Trust for
     purposes of the Closing, and no such shareholders of record will have any
     preemptive rights to purchase any Fund shares, and the Fund does not have
     outstanding any options, warrants or other rights to subscribe for or
     purchase any Fund shares (other than any existing dividend reinvestment
     plans of the Manulife Portfolios or as set forth in this Agreement), nor
     are there outstanding any securities convertible into any shares of the
     Manulife Portfolios (except pursuant to any existing exchange privileges
     described in the current prospectus and statement of additional information
     of the Fund). All of each Manulife Portfolio's issued and outstanding
     shares have been offered and sold in compliance in all material respects
     with applicable registration requirements of the Securities Act and
     applicable state securities laws.
 
          (e) Financial Statements. The financial statements of the Fund for the
     fiscal year ended December 31, 1995, which have been audited by Ernst &
     Young LLP, and the unaudited financial statements of the Fund for the six
     months ended June 30, 1996 (collectively, the "Fund's Financial
     Statements"), previously delivered to the Trust, fairly present the
     financial position of the Fund as of the date thereof, and the results of
     its operations and changes in its net assets for the periods indicated, in
     accordance with GAAP.
 
          (f) Authority Relative to this Agreement. The Fund has the power to
     enter into this Agreement and to carry out its obligations hereunder. The
     execution and delivery of this Agreement and the consummation of the

     effectuate this Agreement and the transactions contemplated hereby. The
     Fund is not a party to or obligated under any provision of its charter or
     by-laws, or under any indenture or contract provision or any other
     commitment or obligation, or subject to any order or decree, which would be

     or contingent and whether or not determined or determinable, other than

     incurred in the ordinary course of business subsequent to June 30, 1996 or

     Portfolio shareholders in connection with the meeting of the Manulife
     Portfolio shareholders for the purpose of acting upon this Agreement and
     the transactions contemplated herein.

     Reorganization, the investment subadvisory agreement between NASL Financial
     Services, Inc. ("NFS") and Wellington Management Company with respect to

          (b) Portfolio Securities. With respect to the assets to be transferred
     in accordance with Section 1(a), each Manulife Portfolio's assets shall
     consist of all property and assets of any nature whatsoever, including,
     without limitation, all cash, cash equivalents, securities, claims and
     receivables (including dividend and interest receivables) owned, and any
     deferred or prepaid expenses shown as an asset on the Fund's books. At
     least five (5) business days prior to the Closing, each Manulife Portfolio
     will provide the Trust with a list of its assets and a list of its stated
     liabilities. Each Manulife Portfolio shall have the right to sell any of
     the securities or other assets shown on the list of assets prior to the
     Closing but will not, without the prior approval of the Trust, acquire any
     additional securities other than securities which the Corresponding NASL
     Portfolio is permitted to purchase, pursuant to its investment objective
     and policies or otherwise (taking into consideration its own portfolio
     composition as of such date). In the event that the Trust informs the Fund
     that a Manulife Portfolio holds any investments that its Corresponding NASL
     Portfolio would not be permitted to hold, the Manulife Portfolio will
     dispose of such securities prior to the Closing to the extent practicable
     and to the extent that its shareholders would not be materially affected in
     an adverse manner by such a disposition. In addition, the Fund will prepare
     and deliver to the Trust, immediately prior to the Effective Time of the
     Reorganization, a Statement of Assets and Liabilities of each Manulife
     Portfolio, prepared in accordance with GAAP (the "Schedule"), which shall
     include a list of all the securities owned by such Manulife Portfolio as of
     the Effective Time of the Reorganization. All securities to be listed in
     the Schedule as of the Effective Time of the Reorganization will be owned
     by the Fund free and clear of any liens, claims, charges, options and
     encumbrances, except as indicated in the Schedule or as permitted by the
     Act, and, except as so indicated, none of such securities is or, after the
     Reorganization as contemplated hereby, will be subject to any restrictions,
     legal or contractual, on the disposition thereof (including restrictions as
     to the public offering or sale thereof under the Securities Act) and,
     except as so indicated, all such securities are or will be readily
     marketable.
 
          (c) Registration Statement. In connection with the preparation of the
     Registration Statement, the Fund will cooperate with the Trust and will
     furnish to the Trust the information relating to the Fund required by the

     fact or omit to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading; and at the time

     shareholders' meeting referred to in Section 5(a) and at the Effective Time
     of the Reorganization, the Prospectus and Statement of Additional
 
                                       12

     Information, as amended or supplemented by any amendments or supplements
     filed by the Trust, insofar as they relate to the Fund, will not contain an
     untrue statement of a material fact or omit to state a material fact
     necessary to make the statements therein, in the light of the circumstances
     under which they were made, not misleading; provided, however, that the
     representations and warranties in this subsection shall apply only to
     statements in or omissions from the Registration Statement, Prospectus or
     Statement of Additional Information made in reliance upon and in conformity
     with information furnished by the Fund for use in the Registration
     Statement, Prospectus or Statement of Additional Information as provided in
     this Section 5(c).
 
          (d) Cooperation in Effecting Reorganization. The Fund agrees to use
     all reasonable efforts to effectuate the Reorganization and to obtain any

     contemplated by this Agreement, the Fund shall conduct its business in the
     ordinary course until the consummation of the Reorganization, it being
     understood that such ordinary course of business will include the
     declaration and payment of customary dividends and distributions.
 
          (f) Contract Terminations. The Fund shall, prior to the Effective Time
     of the Reorganization, terminate all contracts and other commitments (other
     than this Agreement) to which the Fund or any Manulife Portfolio is
     subject, such terminations to be effective as of or prior to the Effective
     Time of the Reorganization.
 
          (g) Exemptive Application. The Fund shall use all reasonable efforts
     to cause the Commission to grant the exemptive relief requested in the

     in any case within 60 days after the Closing Date, the Fund on behalf of
     each Manulife Portfolio shall furnish to the Trust on behalf of each NASL
     Portfolio, in such form as is reasonably satisfactory to the Trust, a
     statement of the earnings and profits of the Manulife Portfolios for
     federal income tax purposes, and of any capital loss carryovers and other
     items that the NASL Portfolios will succeed to and take into account as a
     result of Section 381 of the Code.

6. CONDITIONS PRECEDENT TO OBLIGATIONS OF THE FUND
 
     The obligations of the Fund hereunder with respect to the consummation of
the Reorganization as it relates to each Manulife Portfolio are subject to the
satisfaction of the following conditions:
 
          (a) Approval by the Fund's Shareholders. This Agreement and the
     transactions contemplated by the Reorganization, including, when necessary,
     a temporary amendment of the Manulife Portfolios' investment restrictions
     that might otherwise preclude the consummation of the Reorganization, shall
     have been approved by the requisite vote of the shares of each Manulife
     Portfolio entitled to vote on the matter ("Manulife Shareholder Approval").
 
          (b) Covenants, Warranties and Representations. The Trust shall have
     complied with each of its covenants contained herein, each of the
     representations and warranties contained herein shall be true in all
     material respects as of the Effective Time of the Reorganization (except as
     otherwise contemplated herein), and there shall have been no material
     adverse change (as described in Section 2(i)) in the financial condition,
     results of operations, business, properties or assets of the NASL
     Portfolios since June 30, 1996.
 
          (c) Regulatory Approval. The Registration Statement and the N-1A
     Amendment shall each have been declared effective by the Commission and no
     stop orders under the Securities Act pertaining thereto shall have been
     issued, the Commission shall have granted the exemptive relief requested in
     the Exemptive Application substantially in the form requested in the
     Exemptive Application, and all other approvals, registrations, and
     exemptions under federal and state laws considered to be necessary shall
     have been obtained (collectively, the "Regulatory Approvals").
 
          (d) Tax Opinion. The Fund shall have received the opinion of Simpson
     Thacher & Bartlett (a partnership which includes professional
     corporations), dated on or before the Closing Date, addressed to and in
     form and substance satisfactory to each of the Fund and the Trust, as to
     certain of the federal income tax consequences under the Code of the
     Reorganization, insofar as it relates to each Manulife Portfolio and its
     Corresponding NASL Portfolio, and to shareholders of each Manulife
     Portfolio (the "Tax Opinion"). For purposes of rendering the Tax Opinion,
     Simpson Thacher & Bartlett may rely exclusively and without independent
     verification, as to factual matters, upon the statements made in this
     Agreement, the Prospectus and Statement of Additional Information, and upon
     such other written representations as the President of each of the Fund and
     the Trust will have verified as of the Effective Time of the
     Reorganization. The Tax Opinion will be to the effect that, based on the
     facts and assumptions stated therein, for federal income tax purposes: (i)
     the Reorganization will constitute a reorganization within the meaning of
     section 368(a)(1) of the Code with respect to each Manulife Portfolio and
     its Corresponding NASL Portfolio; (ii) no gain or loss will be recognized
     by any
 
                                       14
<PAGE>   119
 
     of the Manulife Portfolios or the Corresponding NASL Portfolios upon the
     transfer of all the assets and liabilities, if any, of each Manulife
     Portfolio to its Corresponding NASL Portfolio solely in exchange for NASL
     Portfolio Shares or upon the distribution of the NASL Portfolio Shares to
     the holders of Manulife Portfolio Shares solely in exchange for all of
     their Manulife Portfolio Shares; (iii) no gain or loss will be recognized
     by shareholders of any of the Manulife Portfolios upon the exchange of such
     Manulife Portfolio Shares solely for NASL Portfolio Shares; (iv) the
     holding period and tax basis of the NASL Portfolio Shares received by each
     holder of Manulife Portfolio Shares pursuant to the Reorganization will be
     the same as the holding period (provided the Manulife Portfolio Shares were
     held as a capital asset on the date of the Reorganization) and tax basis of
     the Manulife Portfolio Shares held by the shareholder immediately prior to
     the Reorganization; and (v) the holding period and tax basis of the assets
     of each of the Manulife Portfolios acquired by its Corresponding NASL
     Portfolio will be the same as the holding period and tax basis of those
     assets to each of the Manulife Portfolios immediately prior to the
     Reorganization. The payment by NFS or its affiliates of the Reorganization
     expenses referred to in Section 9 hereof will not affect the opinions set
     forth above regarding the tax consequences of the exchanges by the Fund and
     the shareholders of the Fund; however, Simpson Thacher & Bartlett will
     express no opinion as to any federal income tax consequences to any of the
     parties of the payment of such expenses by NFS or its affiliates.
 
          (e) Board of Trustees Approvals. The Board of Trustees of the Trust
     shall have taken the following action with respect to the Trust or the NASL

             (i) approve the investment advisory agreement between the Trust and
        NFS with respect to each of the New NASL Portfolios, as contemplated by

                               INVESTMENT POLICIES

The following discussion supplements the discussion set forth in the
Prospectus/Proxy Statement under "Comparison of Investment Objectives and
Policies".


MONEY MARKET INSTRUMENTS

The NASL Money Market Trust will be invested in the types of money market
instruments described below. Certain of the instruments listed below may also be
purchased by the other NASL Portfolios in accordance with their investment
policies and all NASL Portfolios may purchase such instruments to invest
otherwise idle cash or for defensive purposes, except that the NASL Equity Index
Trust may not invest in the instruments described in 2. below.

      1. U.S. GOVERNMENT AND GOVERNMENT AGENCY OBLIGATIONS. Government
obligations are debt securities issued or guaranteed as to principal or interest
by the U.S. Treasury. These securities include treasury bills, notes and bonds.
U.S. Government agency obligations are debt securities issued or guaranteed as
to principal or interest by an agency or instrumentality of the U.S. Government
pursuant to authority granted by Congress. U.S. Government agency obligations
include, but are not limited to, the Student Loan Marketing Association, Federal
Home Loan Banks, Federal Intermediate Credit Banks and the Federal National
Mortgage Association. U.S. instrumentality obligations include, but are not
limited to, the Export-Import Bank and Farmers Home Administration. Some
obligations issued or guaranteed by U.S. Government agencies or
instrumentalities are supported by the right of the issuer to borrow from the
U.S. Treasury or the Federal Reserve Banks, such as those issued by Federal
Intermediate Credit Banks; others, such as those issued by the Federal National
Mortgage Association, by discretionary authority of the U.S. Government to
purchase certain obligations of the agency or instrumentality; and others, such
as those issued by the Student Loan Marketing Association, only by the credit of
the agency or instrumentality. There are also separately traded interest
components of securities issued or guaranteed by the United States Treasury. No
assurance can be given that the U.S. Government will provide financial support
to such U.S. Government sponsored agencies or instrumentalities in the future,
since it is not obligated to do so by law. The foregoing types of instruments
are hereafter collectively referred to as "U.S. Government securities."

      2. CANADIAN AND PROVINCIAL GOVERNMENT AND CROWN AGENCY Obligations.
Canadian Government obligations are debt securities issued or guaranteed as to
principal or interest by the Government of Canada pursuant to authority granted
by the Parliament of Canada and approved by the Governor in Council, where
necessary. These securities include treasury bills, notes, bonds, debentures and
marketable Government of Canada loans. Canadian Crown agency obligations are
debt securities issued or guaranteed by a Crown corporation, company or agency
("Crown agencies") pursuant to authority granted by the Parliament of Canada and
approved by the Governor in Council, where necessary. Certain Crown agencies are
by statute agents of Her Majesty in right of Canada, and their obligations, when
properly authorized, constitute direct obligations of the Government of Canada.
Such obligations include, but are not limited to, those issued or guaranteed by
the Export Development Corporation, Farm Credit Corporation, Federal Business
Development Bank and Canada Post Corporation. In addition, certain Crown
agencies which are not by law agents of Her Majesty may issue obligations which
by statute the Governor in Council may authorize the Minister of Finance to
guarantee on behalf of the Government of Canada. Other Crown agencies which are
not by law agents of Her Majesty may issue or guarantee obligations not entitled
to be guaranteed by the Government of Canada. No assurance can be given that the
Government of Canada will support the obligations of Crown agencies which are
not agents of Her Majesty, which it has not guaranteed, since it is not
obligated to do so by law.

      Provincial Government obligations are debt securities issued or guaranteed
as to principal or interest by the government of any province of Canada pursuant
to authority granted by the Legislature of any such province and approved by the
Lieutenant Governor in Council of any such province, where necessary. These
securities include treasury bills, notes, bonds and debentures. Provincial Crown
agency obligations are debt securities issued or guaranteed by a provincial
Crown corporation, company or agency ("provincial Crown agencies") pursuant to
authority granted by a provincial Legislature and approved by the Lieutenant
Governor in Council of such province, where necessary. Certain provincial Crown
agencies are by statute agents of Her Majesty in right of a particular province
of Canada, and their obligations, when properly authorized, constitute direct
obligations of such province. Other provincial Crown agencies which are not by
law agents of Her Majesty in right of a particular province of Canada may issue
obligations which by statute the Lieutenant Governor in Council of such province
may guarantee, or may authorize the Treasurer thereof to guarantee, on behalf of
the government of such province. Finally, other provincial Crown agencies which
are not by law agencies of Her Majesty may issue or guarantee obligations not
entitled to be guaranteed by a provincial government. No assurance can be given
that the government of any province of Canada will support the obligations of
provincial Crown agencies which are not agents of Her Majesty, which it has not
guaranteed, as it is not obligated to do so by law. Provincial Crown agency
obligations described above include, but are not



<PAGE>   130



limited to, those issued or guaranteed by a provincial railway corporation, a
provincial hydroelectric or power commission or authority, a provincial
municipal financing corporation or agency and a provincial telephone commission
or authority.

      Any Canadian obligation acquired by the NASL Money Market Trust will be
payable in U.S. dollars.

      3. CERTIFICATES OF DEPOSIT AND BANKERS' ACCEPTANCES. Certificates of
deposit are certificates issued against funds deposited in a bank or a savings
and loan. They are for a definite period of time and earn a specified rate of
return. Bankers' acceptances are short-term credit instruments evidencing the
obligation of a bank to pay a draft which has been drawn on it by a customer.
These instruments reflect the obligation both of the bank and of the drawer to
pay the face amount of the instrument upon maturity. They are primarily used to
finance the import, export, transfer or storage of goods. They are termed
"accepted" when a bank guarantees their payment at maturity.

      NASL Portfolios may acquire obligations of foreign banks and foreign
branches of U.S. banks. These obligations are not insured by the Federal Deposit
Insurance Corporation.

      4. COMMERCIAL PAPER. Commercial paper consists of unsecured promissory
notes issued by corporations to finance short-term credit needs. Commercial
paper is issued in bearer form with maturities generally not exceeding nine
months. Commercial paper obligations may include variable amount master demand
notes. Variable amount master demand notes are obligations that permit the
investment of fluctuating amounts at varying rates of interest pursuant to
direct arrangements between a NASL Portfolio, as lender, and the borrower. These
notes permit daily changes in the amounts borrowed. The NASL Portfolio has the
right to increase the amount under the note at any time up to the full amount
provided by the note agreement, or to decrease the amount, and the borrower may
prepay up to the full amount of the note without penalty. Because variable
amount master demand notes are direct lending arrangements between the lender
and borrower, it is not generally contemplated that such instruments will be
traded, and there is no secondary market for these notes, although they are
redeemable (and thus immediately repayable by the borrower) at face value, plus
accrued interest, at any time. A NASL Portfolio will only invest in variable
amount master demand notes issued by companies which at the date of investment
have an outstanding debt issue rated "Aaa" or "Aa" by Moody's or "AAA" or "AA"
by S&P and which the applicable subadviser has determined present minimal risk
of loss to the NASL Portfolio. A subadviser will look generally at the financial
strength of the issuing company as "backing" for the note and not to any
security interest or supplemental source such as a bank letter of credit. A
master demand note will be valued each day a NASL Portfolio's net asset value is
determined, which value will generally be equal to the face value of the note
plus accrued interest unless the financial position of the issuer is such that
its ability to repay the note when due is in question.

      5. CORPORATE OBLIGATIONS. Corporate obligations include bonds and notes
issued by corporations to finance long-term credit needs.

      6. REPURCHASE AGREEMENTS. Repurchase agreements are arrangements involving
the purchase of obligations by a NASL Portfolio and the simultaneous agreement
to resell the same obligations on demand or at a specified future date and at an
agreed upon price. A repurchase agreement can be viewed as a loan made by a NASL
Portfolio to the seller of the obligation with such obligation serving as
collateral for the seller's agreement to repay the amount borrowed with
interest. Such transactions afford an opportunity for a NASL Portfolio to earn a
return on cash which is only temporarily available. Repurchase agreements
entered into by the NASL Portfolio will be with banks, brokers or dealers.
However, a NASL Portfolio will enter into a repurchase agreement with a broker
or dealer only if the broker or dealer agrees to deposit additional collateral
should the value of the obligation purchased by the NASL Portfolio decrease
below the resale price.

      In selecting sellers with whom the NASL Portfolio will enter into
repurchase transactions, NASL's Board of Trustees (the "NASL Board") has adopted
procedures that establish certain credit worthiness, asset and collateralization
requirements and limit the counterparties to repurchase transactions to those
financial institutions which are members of the Federal Reserve System and for a
primary government securities dealer reporting to the Federal Reserve Bank of
New York's Market Reports Division or a broker/dealer which meet certain credit
worthiness criteria or which report U.S. Government securities positions to the
Federal Reserve Board. However, the NASL Board reserves the right to change the
criteria used to select such financial institutions and broker/dealers. The NASL
Board will regularly monitor the use of repurchase agreements and the subadviser
will, pursuant to procedures adopted by the NASL Board, continuously monitor
that the collateral held with respect to a repurchase transaction equals or
exceeds the amount of the obligations.

      Should an issuer of a repurchase agreement fail to repurchase the
underlying obligation, the loss to the NASL Portfolio, if any, would be the
difference between the repurchase price and the underlying obligation's market
value. A NASL Portfolio might also incur certain costs in liquidating the
underlying obligation. Moreover, if bankruptcy or other insolvency proceedings

                                       -2-


<PAGE>   131



should be commenced with respect to the seller, realization upon the underlying
obligation by NASL might be delayed or limited. Generally, repurchase agreements
are of a short duration, often less than one week but on occasion for longer
periods.


OTHER INSTRUMENTS

   
      The following provides a more detailed explanation of some of the other
instruments in which certain NASL Portfolios may invest.
    

1. MORTGAGE SECURITIES

      Mortgage securities differ from conventional bonds in that principal is
paid over the life of the securities rather than at maturity. As a result, a
NASL Portfolio receives monthly scheduled payments of principal and interest,
and may receive unscheduled principal payments representing prepayments on the
underlying mortgages. When a NASL Portfolio reinvests the payments and any
unscheduled prepayments of principal it receives, it may receive a rate of
interest which is higher or lower than the rate on the existing mortgage
securities. For this reason, mortgage securities may be less effective than
other types of debt securities as a means of locking in long term interest
rates.

      In addition, because the underlying mortgage loans and assets may be
prepaid at any time, if a NASL Portfolio purchases mortgage securities at a
premium, a prepayment rate that is faster than expected will reduce yield to
maturity, while a prepayment rate that is slower than expected will have the
opposite effect of increasing yield to maturity. Conversely, if a NASL Portfolio
purchases these securities at a discount, faster than expected prepayments will
increase, while slower than expected payments will reduce, yield to maturity.

      Adjustable rate mortgage securities, are similar to the mortgage
securities discussed above, except that unlike fixed rate mortgage securities,
adjustable rate mortgage securities are collateralized by or represent interests
in mortgage loans with variable rates of interest. These variable rates of
interest reset periodically to align themselves with market rates. Most
adjustable rate mortgage securities provide for an initial mortgage rate that is
in effect for a fixed period, typically ranging from three to twelve months.
Thereafter, the mortgage interest rate will reset periodically in accordance
with movements in a specified published interest rate index. The amount of
interest due to an adjustable rate mortgage holder is determined in accordance
with movements in a specified published interest rate index by adding a
pre-determined increment or "margin" to the specified interest rate index. Many
adjustable rate mortgage securities reset their interest rates based on changes
in the one-year, three-year and five-year constant maturity Treasury rates, the
three-month or six-month Treasury Bill rate, the 11th District Federal Home Loan
Bank Cost of Funds, the National Median Cost of Funds, the one-month,
three-month, six-month or one-year London Interbank Offered Rate ("LIBOR") and
other market rates.

      A NASL portfolio will not benefit from increases in interest rates to the
extent that interest rates rise to the point where they cause the current coupon
of adjustable rate mortgages held as investments to exceed any maximum allowable
annual or lifetime reset limits (or "cap rates") for a particular mortgage. In
this event, the value of the mortgage securities in a NASL Portfolio would
likely decrease. Also, the NASL Portfolio's net asset value could vary to the
extent that current yields on adjustable rate mortgage securities are different
than market yields during interim periods between coupon reset dates. During
periods of declining interest rates, income to a NASL Portfolio derived from
adjustable rate mortgages which remain in a mortgage pool will decrease in
contrast to the income on fixed rate mortgages, which will remain constant.
Adjustable rate mortgages also have less potential for appreciation in value as
interest rates decline than do fixed rate investments.

      Privately-Issued Mortgage Securities. Privately-issued pass through
securities provide for the monthly principal and interest payments made by
individual borrowers to pass through to investors on a corporate basis, and in
privately issued collateralized mortgage obligations, as further described
below. Privately-issued mortgage securities are issued by private originators
of, or investors in, mortgage loans, including mortgage bankers, commercial
banks, investment banks, savings and loan associations and special purpose
subsidiaries of the foregoing. Since privately-issued mortgage certificates are
not guaranteed by an entity having the credit status of GNMA or FHLMC, such
securities generally are structured with one or more types of credit
enhancement. For a description of the types of credit enhancements that may
accompany privately-issued mortgage securities, see "Types of Credit Support"
below. A NASL Portfolio will not limit its investments to asset-backed
securities with credit enhancements.

      Collateralized Mortgage Obligations ("CMOs"). CMOs generally are bonds or
certificates issued in multiple classes that are collateralized by or represent
an interest in mortgages. CMOs may be issued by single-purpose, stand-alone
finance subsidiaries or trusts of financial institutions, government agencies,
investment banks or other similar institutions. Each class of CMOs, often
referred to as a "tranche", may be issued with a specific fixed coupon rate
(which may be zero) or a floating

                                       -3-


<PAGE>   132



coupon rate, and has a stated maturity or final distribution date. Principal
prepayments on the underlying mortgages may cause the CMOs to be retired
substantially earlier than their stated maturities or final distribution dates.
Interest is paid or accrued on CMOs on a monthly, quarterly or semiannual basis.
The principal of and interest on the underlying mortgages may be allocated among
the several classes of a series of a CMO in many ways. The general goal sought
to be achieved in allocating cash flows on the underlying mortgages to the
various classes of a series of CMOs is to create tranches on which the expected
cash flows have a higher degree of predictability than the underlying mortgages.
As a general matter, the more predictable the cash flow is on a CMO tranche, the
lower the anticipated yield will be on that tranche at the time of issuance. As
part of the process of creating more predictable cash flows on most of the
tranches in a series of CMOs, one or more tranches generally must be created
that absorb most of the volatility in the cash flows on the underlying
mortgages. The yields on these tranches are relatively higher than on tranches
with more predictable cash flows. Because of the uncertainty of the cash flows
on these tranches, and the sensitivity thereof to changes in prepayment rates on
the underlying mortgages, the market prices of and yield on these tranches tend
to be highly volatile.

   CMOs purchased may be:

      (1) collateralized by pools of mortgages in which each mortgage is
      guaranteed as to payment of principal and interest by an agency or
      instrumentality of the U.S. Government;

      (2) collateralized by pools of mortgages in which payment of principal and
      interest is guaranteed by the issuer and the guarantee is collateralized
      by U.S. Government securities; or

      (3) securities for which the proceeds of the issuance are invested in
      mortgage securities and payment of the principal and interest is supported
      by the credit of an agency or instrumentality of the U.S. Government.

      STRIPS. In addition to the U.S. Government securities discussed above,
certain NASL Portfolios may invest in separately traded interest components of
securities issued or guaranteed by the United States Treasury. The interest
components of selected securities are traded independently under the Separate
Trading of Registered Interest and Principal of Securities program ("STRIPS").
Under the STRIPS program, the interest components are individually numbered and
separately issued by the United States Treasury at the request of depository
financial institutions, which then trade the component parts independently.

      Stripped Mortgage Securities. Stripped mortgage securities are derivative
multiclass mortgage securities. Stripped mortgage securities may be issued by
agencies or instrumentalities of the U.S. Government, or by private issuers,
including savings and loan associations, mortgage banks, commercial banks,
investment banks and special purpose subsidiaries of the foregoing. Stripped
mortgage securities have greater volatility than other types of mortgage
securities in which the NASL Portfolio invests. Although stripped mortgage
securities are purchased and sold by institutional investors through several
investment banking firms acting as brokers or dealers, the market for such
securities has not yet been fully developed. Accordingly, stripped mortgage
securities are generally illiquid and to such extent, together with any other
illiquid investments, will not exceed 15% of a NASL Portfolio's net assets.

      Stripped mortgage securities are usually structured with two classes that
receive different proportions of the interest and principal distributions on a
pool of mortgage assets. A common type of stripped mortgage security will have
one class receiving some of the interest and most of the principal from the
mortgage assets, while the other class will receive most of the interest and the
remainder of the principal. In the most extreme case, one class will receive all
of the interest (the interest only or "IO" class), while the other class will
receive all of the principal (the principal only or "PO" class). The yield to
maturity on an IO class is extremely sensitive not only to changes in prevailing
interest rates but also the rate of principal payments (including prepayments)
on the related underlying mortgage assets, and a rapid rate of principal
payments may have a material adverse effect on the NASL Portfolio's yield to
maturity. If the underlying mortgage assets experience greater than anticipated
prepayments of principal, the NASL Portfolio may fail to fully recoup its
initial investment in these securities even if the securities are rated AAA by
S&P.

      As interest rates rise and fall, the value of IOs tends to move in the
same direction as interest rates. The value of the other mortgage securities
described in the Prospectus/Proxy Statement, like other debt instruments, will
tend to move in the opposite direction to interest rates. Accordingly, NASL
believes that investing in IOs, in conjunction with the other mortgage
securities described herein, will contribute to a NASL Portfolio's relatively
stable net asset value.
   
    

      Under the Internal Revenue Code of 1986, as amended (the "Code"), POs may
generate taxable income from the current accrual of original issue discount,
without a corresponding distribution of cash to the NASL Portfolio. See
"Additional Information Concerning Taxes."

2. ASSET-BACKED SECURITIES

      The securitization techniques used to develop mortgage securities are also
being applied to a broad range of other assets. Through the use of trusts and
special purpose corporations, automobile and credit card receivables are being
securitized in pass-through structures similar to mortgage pass-through
structures or in a pay-through structure similar to the CMO structure. Generally
the issuers of asset-backed bonds, notes or pass-through certificates are
special purpose entities and do not have any significant assets other than the
receivables securing such obligations. In general, the collateral supporting
asset-backed securities is of shorter maturity than mortgage loans. As a result,
investment in these securities should result in greater price stability for the
NASL Portfolio's shares. Instruments backed by pools of receivables are similar
to mortgage-backed securities in that they are subject to unscheduled
prepayments of principal prior to maturity. When the obligations are prepaid,
the NASL Portfolio must reinvest the prepaid amounts in securities the yields of
which reflect interest rates prevailing at the time. Therefore, a NASL
Portfolio's ability to maintain a portfolio which includes high-yielding
asset-backed securities will be adversely affected to the extent that
prepayments of principal must be reinvested in securities which have lower
yields than the prepaid obligations. Moreover, prepayments of securities
purchased at a premium could result in a realized loss. A NASL Portfolio will
only invest in asset-backed securities rated, at the time of purchase, AA or
better by S&P or Aa or better by Moody's or which, in the opinion of the
investment subadviser, are of comparable quality.

      As with mortgage securities, asset-backed securities are often backed by a
pool of assets representing the obligation of a number of different parties and
use similar credit enhancement techniques. For a description of the types of
credit enhancement that may accompany privately-issued mortgage securities, see
"Types of Credit Support" below. A NASL Portfolio will not limit its investments
to asset-backed securities with credit enhancements. Although asset-backed
securities are not generally traded on a national securities exchange, such
securities are widely traded by brokers and dealers, and to such extent will not
be considered illiquid securities for the purposes of the investment restriction
under "Investment Restrictions" below.

      TYPES OF CREDIT SUPPORT. Mortgage securities and asset-backed securities
are often backed by a pool of assets representing the obligations of a number of
different parties. To lessen the effect of failure by obligors on underlying
assets to make payments, such securities may contain elements of credit support.
Such credit support falls into two categories: (i) liquidity protection and (ii)
protection against losses resulting from ultimate default by an obligor on the
underlying assets. Liquidity protection refers to the provision of advances,
generally by the entity administering the pool of assets, to ensure that the
pass-through of payments due on the underlying pool occurs in a timely fashion.
Protection against losses resulting from ultimate default enhances the
likelihood of ultimate payment of the obligations on at least a portion of the
assets in the pool. Such protection may be provided through guarantees,
insurance policies or letters of credit obtained by the issuer or sponsor from
third parties, through various means of structuring the transaction or through a
combination of such approaches. NASL will not pay any additional fees for such
credit support, although the existence of credit support may increase the price
of a security.

      The ratings of mortgage securities and asset-backed securities for which
third-party credit enhancement provides liquidity protection or protection
against losses from default are generally dependent upon the continued
creditworthiness of the provider of the credit enhancement. The ratings of such
securities could be subject to reduction in the event of deterioration in the
creditworthiness of the credit enhancement provider even in cases where the
delinquency and loss experience on the underlying pool of assets is better than
expected.

      Examples of credit support arising out of the structure of the transaction
include "senior-subordinated securities" (multiple class securities with one or
more classes subordinate to other classes as to the payment of principal thereof
and interest thereon, with the result that defaults on the underlying assets are
borne first by the holders of the subordinated class), creation of "reserve
funds" (where cash or investments sometimes funded from a portion of the
payments on the underlying assets, are held in reserve against future losses)
and "over-collateralization" (where the scheduled payments on, or the principal
amount of, the underlying assets exceed those required to make payment of the
securities and pay any servicing or other fees). The degree of credit support
provided for each issue is generally based on historical information with
respect to the level of credit risk associated with the underlying assets.
Delinquency or loss in excess of that which is anticipated could adversely
affect the return on an investment in such security.

3. ZERO COUPON SECURITIES AND PAY-IN-KIND BONDS

      Zero coupon securities and pay-in-kind bonds involve special risk
considerations. Zero coupon securities are debt securities that pay no cash
income but are sold at substantial discounts from their value at maturity. When
a zero coupon security is held to maturity, its entire return, which consists of
the amortization of discount, comes from the difference

                                       -5-


<PAGE>   134



between its purchase price and its maturity value. This difference is known at
the time of purchase, so that investors holding zero coupon securities until
maturity know at the time of their investment what the return on their
investment will be. Certain zero coupon securities also are sold at substantial
discounts from their maturity value and provide for the commencement of regular
interest payments at a deferred date. The NASL Portfolios also may purchase
pay-in-kind bonds. Pay-in-kind bonds are bonds that pay all or a portion of
their interest in the form of debt or equity securities.

      Zero coupon securities and pay-in-kind bonds tend to be subject to greater
price fluctuations in response to changes in interest rates than are ordinary
interest-paying debt securities with similar maturities. The value of zero
coupon securities appreciates more during periods of declining interest rates
and depreciates more during periods of rising interest rates.

      Zero coupon securities and pay-in-kind bonds may be issued by a wide
variety of corporate and governmental issuers. Although zero coupon securities
and pay-in-kind bonds are generally not traded on a national securities
exchange, such securities are widely traded by brokers and dealers and, to such
extent, will not be considered illiquid for the purposes of the investment
restriction under "Investment Restrictions" below.

      Current federal income tax law requires the holder of a zero coupon
security or certain pay-in-kind bonds to accrue income with respect to these
securities prior to the receipt of cash payments. To maintain its qualification
as a regulated investment company and avoid liability for federal income and
excise taxes, a NASL Portfolio may be required to distribute income accrued with
respect to these securities and may have to dispose of portfolio securities
under disadvantageous circumstances in order to generate cash to satisfy these
distribution requirements. See "Taxes--Pay-in-kind Bonds and Zero Coupon Bonds"
below.

4. HIGH YIELD (HIGH RISK) DOMESTIC CORPORATE DEBT SECURITIES

      The market for high yield U.S. corporate debt securities has undergone
significant changes in the past decade. Issuers in the U.S. high yield market
originally consisted primarily of growing small capitalization companies and
larger capitalization companies whose credit quality had declined from
investment grade. During the mid-1980's, participants in the U.S. high yield
market issued high yield securities principally in connection with leveraged
buyouts and other leveraged recapitalizations. In late 1989 and 1990, the volume
of new issues of high yield U.S. corporate debt declined significantly and
liquidity in the market decreased. Since early 1991, the volume of new issues of
high yield U.S. corporate debt securities has increased substantially and
secondary market liquidity has improved. During the same periods, the U.S. high
yield debt market exhibited strong returns, and it continues to be an attractive
market in terms of yield and yield spread over U.S. Treasury securities.
Currently, most new offerings of U.S. high yield securities are being issued to
refinance higher coupon debt and to raise funds for general corporate purposes.

      High yield U.S. corporate debt securities in which the NASL Portfolios may
invest include bonds, debentures, notes and commercial paper and will generally
be unsecured. Most of these debt securities will bear interest at fixed rates.
However, the NASL Portfolios may also invest in debt securities with variable
rates of interest or which involve equity features, such as contingent interest
or participations based on revenues, sales or profits (i.e., interest or other
payments, often in addition to a fixed rate of return, that are based on the
borrower's attainment of specified levels of revenues, sales or profits and thus
enable the holder of the security to share in the potential success of the
venture).

   
5. HYBRID INSTRUMENTS
    

      Hybrid instruments (a type of potentially high-risk derivative) have been
developed and combine the elements of futures contracts or options with those of
debt, preferred equity or a depository instrument (hereinafter "Hybrid
Instruments"). Generally, a Hybrid Instrument will be a debt security, preferred
stock, depository share, trust certificate, certificate of deposit or other
evidence of indebtedness on which a portion of or all interest payments, and/or
the principal or stated amount payable at maturity, redemption or retirement, is
determined by reference to prices, changes in prices, or differences between
prices, of securities, currencies, intangibles, goods, articles or commodities
(collectively "Underlying Assets") or by another objective index, economic
factor or other measure, such as interest rates, currency exchange rates,
commodity indices, and securities indices (collectively "Benchmarks"). Thus,
Hybrid Instruments may take a variety of forms, including, but not limited to,
debt instruments with interest or principal payments or redemption terms
determined by reference to the value of a currency or commodity or securities
index at a future point in time, preferred stock with dividend rates determined
by reference to the value of a currency, or convertible securities with the
conversion terms related to a particular commodity.

      Hybrid Instruments can be an efficient means of creating exposure to a
particular market, or segment of a market, with the objective of enhancing total
return. For example, a NASL Portfolio may wish to take advantage of expected
declines in interest rates in several European countries, but avoid the
transactions costs associated with buying and currency-hedging the

                                       -6-


<PAGE>   135



foreign bond positions. One solution would be to purchase a U.S. dollar-
denominated Hybrid Instrument whose redemption price is linked to the average
three year interest rate in a designated group of countries. The redemption
price formula would provide for payoffs of greater than par if the average
interest rate was lower than a specified level, and payoffs of less than par if
rates were above the specified level. Furthermore, the NASL Portfolio could
limit the downside risk of the security by establishing a minimum redemption
price so that the principal paid at maturity could not be below a predetermined
minimum level if interest rates were to rise significantly. The purpose of this
arrangement, known as a structured security with an embedded put option, would
be to give the NASL Portfolio the desired European bond exposure while avoiding
currency risk, limiting downside market risk, and lowering transactions costs.
Of course, there is no guarantee that the strategy will be successful and the
NASL Portfolio could lose money if, for example, interest rates do not move as
anticipated or credit problems develop with the issuer of the Hybrid.

      The risks of investing in Hybrid Instruments reflect a combination of the
risks of investing in securities, options, futures and currencies. Thus, an
investment in a Hybrid Instrument may entail significant risks that are not
associated with a similar investment in a traditional debt instrument that has a
fixed principal amount, is denominated in U.S. dollars or bears interest either
at a fixed rate or a floating rate determined by reference to a common,
nationally published Benchmark. The risks of a particular Hybrid Instrument
will, of course, depend upon the terms of the instrument, but may include,
without limitation, the possibility of significant changes in the Benchmarks or
the prices of Underlying Assets to which the instrument is linked. Such risks
generally depend upon factors which are unrelated to the operations or credit
quality of the issuer of the Hybrid Instrument and which may not be readily
foreseen by the purchaser, such as economic and political events, the supply and
demand for the Underlying Assets and interest rate movements. In recent years,
various Benchmarks and prices for Underlying Assets have been highly volatile,
and such volatility may be expected in the future. Reference is also made to the
discussion below of futures, options, and forward contracts for a description of
certain risks associated with such investments.

      Hybrid Instruments are potentially more volatile and carry greater market
risks than traditional debt instruments. Depending on the structure of the
particular Hybrid Instrument, changes in a Benchmark may be magnified by the
terms of the Hybrid Instrument and have an even more dramatic and substantial
effect upon the value of the Hybrid Instrument. Also, the prices of the Hybrid
Instrument and the Benchmark or Underlying Asset may not move in the same
direction or at the same time.

      Hybrid Instruments may bear interest or pay preferred dividends at below
market (or even relatively nominal) rates. Alternatively, Hybrid Instruments may
bear interest at above market rates but bear an increased risk of principal loss
(or gain). The latter scenario may result if "leverage" is used to structure the
Hybrid Instrument. Leverage risk occurs when the Hybrid Instrument is structured
so that a given change in a Benchmark or Underlying Asset is multiplied to
produce a greater value change in the Hybrid Instrument, thereby magnifying the
risk of loss as well as the potential for gain.

      Hybrid Instruments may also carry liquidity risk since the instruments are
often "customized" to meet the portfolio needs of a particular investor, and
therefore, the number of investors that are willing and able to buy such
instruments in the secondary market may be smaller than that for more
traditional debt securities. In addition, because the purchase and sale of
Hybrid Instruments could take place in an over-the-counter market without the
guarantee of a central clearing organization or in a transaction between the
NASL Portfolio and the issuer of the Hybrid Instrument, the creditworthiness of
the counter party or issuer of the Hybrid Instrument would be an additional risk
factor which the NASL Portfolio would have to consider and monitor. Hybrid
Instruments also may not be subject to regulation of the Commodities Futures
Trading Commission ("CFTC"), which generally regulates the trading of commodity
futures by U.S. persons, the SEC, which regulates the offer and sale of
securities by and to U.S. persons, or any other governmental regulatory
authority. The various risks discussed above, particularly the market risk of
such instruments, may in turn cause significant fluctuations in the net asset
value of the NASL Portfolio.


                    HEDGING AND OTHER STRATEGIC TRANSACTIONS

      As described in the Prospectus/Proxy Statement under "Comparison of
Investment Objectives and Policies--J. Additional Information on Investment
Policies and Techniques and Risk Factors--Hedging and Other Strategic
Transactions", an individual NASL Portfolio may be authorized to use a variety
of investment strategies. These strategies will be used 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 NASL Portfolio
(such investment strategies and transactions are referred to herein as "Hedging
and Other Strategic Transactions"). The description in the Prospectus/Proxy
Statement of each NASL Portfolio indicates which, if any, of these types of
transactions may be used by the NASL Portfolio.

                                       -7-


<PAGE>   136



      A detailed discussion of Hedging and Other Strategic Transactions follows
below. No NASL Portfolio which is authorized to use any of these investment
strategies will be obligated, however, to pursue any of such strategies and no
NASL Portfolio makes any representation as to the availability of these
techniques at this time or at any time in the future. In addition, a NASL
Portfolio's ability to pursue certain of these strategies may be limited by the
Commodity Exchange Act, as amended, applicable rules and regulations of the CFTC
thereunder and the federal income tax requirements applicable to regulated
investment companies which are not operated as commodity pools.


GENERAL CHARACTERISTICS OF OPTIONS

      Put options and call options typically have similar structural
characteristics and operational mechanics regardless of the underlying
instrument on which they are purchased or sold. Thus, the following general
discussion relates to each of the particular types of options discussed in
greater detail below. In addition, many Hedging and Other Strategic Transactions
involving options require segregation of portfolio assets in special accounts,
as described below under "Use of Segregated and Other Special Accounts."

      A put option gives the purchaser of the option, upon payment of a premium,
the right to sell, and the writer the obligation to buy, the underlying
security, commodity, index, currency or other instrument at the exercise price.
A NASL Portfolio's purchase of a put option on a security, for example, might be
designed to protect its holdings in the underlying instrument (or, in some
cases, a similar instrument) against a substantial decline in the market value
of such instrument by giving the NASL Portfolio the right to sell the instrument
at the option exercise price. A call option, upon payment of a premium, gives
the purchaser of the option the right to buy, and the seller the obligation to
sell, the underlying instrument at the exercise price. A NASL Portfolio's
purchase of a call option on a security, financial futures contract, index,
currency or other instrument might be intended to protect the NASL Portfolio
against an increase in the price of the underlying instrument that it intends to
purchase in the future by fixing the price at which it may purchase the
instrument. An "American" style put or call option may be exercised at any time
during the option period, whereas a "European" style put or call option may be
exercised only upon expiration or during a fixed period prior to expiration.
Exchange-listed options are issued by a regulated intermediary such as the
Options Clearing Corporation ("OCC"), which guarantees the performance of the
obligations of the parties to the options. The discussion below uses the OCC as
an example, but is also applicable to other similar financial intermediaries.

      OCC-issued and exchange-listed options, with certain exceptions, generally
settle by physical delivery of the underlying security or currency, although in
the future, cash settlement may become available. Index options and Eurodollar
instruments (which are described below under "Eurodollar Instruments") are cash
settled for the net amount, if any, by which the option is "in-the-money" (that
is, the amount by which the value of the underlying instrument exceeds, in the
case of a call option, or is less than, in the case of a put option, the
exercise price of the option) at the time the option is exercised. Frequently,
rather than taking or making delivery of the underlying instrument through the
process of exercising the option, listed options are closed by entering into
offsetting purchase or sale transactions that do not result in ownership of the
new option.

      A NASL Portfolio's ability to close out its position as a purchaser or
seller of an OCC-issued or exchange-listed put or call option is dependent, in
part, upon the liquidity of the particular option market. Among the possible
reasons for the absence of a liquid option market on an exchange are: (1)
insufficient trading interest in certain options, (2) restrictions on
transactions imposed by an exchange, (3) trading halts, suspensions or other
restrictions imposed with respect to particular classes or series of options or
underlying securities, including reaching daily price limits, (4) interruption
of the normal operations of the OCC or an exchange, (5) inadequacy of the
facilities of an exchange or the OCC to handle current trading volume or (6) a
decision by one or more exchanges to discontinue the trading of options (or a
particular class or series of options), in which event the relevant market for
that option on that exchange would cease to exist, although any such outstanding
options on that exchange would continue to be exercisable in accordance with
their terms.

      The hours of trading for listed options may not coincide with the hours
during which the underlying financial instruments are traded. To the extent that
the option markets close before the markets for the underlying financial
instruments, significant price and rate movements can take place in the
underlying markets that would not be reflected in the corresponding option
markets.

      Over-the-counter ("OTC") options are purchased from or sold to securities
dealers, financial institutions or other parties (collectively referred to as
"Counterparties" and individually referred to as a "Counterparty") through
direct bilateral agreement with the Counterparty. In contrast to exchange-listed
options, which generally have standardized terms and performance mechanics, all
of the terms of an OTC option, including such terms as method of settlement,
term, exercise price, premium, guaranties and security, are determined by
negotiation of the parties. It is anticipated that any NASL Portfolio authorized
to

                                       -8-


<PAGE>   137



use OTC options will generally only enter into OTC options that have cash
settlement provisions, although it will not be required to do so.

      Unless the parties provide for it, no central clearing or guaranty
function is involved in an OTC option. As a result, if a Counterparty fails to
make or take delivery of the security, currency or other instrument underlying
an OTC option it has entered into with a NASL Portfolio or fails to make a cash
settlement payment due in accordance with the terms of that option, the NASL
Portfolio will lose any premium it paid for the option as well as any
anticipated benefit of the transaction. Thus, the subadviser must assess the
creditworthiness of each such Counterparty or any guarantor or credit
enhancement of the Counterparty's credit to determine the likelihood that the
terms of the OTC option will be met. A NASL Portfolio will enter into OTC option
transactions only with U.S. Government securities dealers recognized by the
Federal Reserve Bank of New York as "primary dealers," or broker-dealers,
domestic or foreign banks, or other financial institutions that are deemed
creditworthy by the subadviser. In the absence of a change in the current
position of the staff of the Commission, OTC options purchased by a NASL
Portfolio and the amount of the NASL Portfolio's obligation pursuant to an OTC
option sold by the NASL Portfolio (the cost of the sell-back plus the
in-the-money amount, if any) or the value of the assets held to cover such
options will be deemed illiquid.

      If a NASL Portfolio sells a call option, the premium that it receives may
serve as a partial hedge, to the extent of the option premium, against a
decrease in the value of the underlying securities or instruments held by the
NASL Portfolio or will increase the NASL Portfolio's income. Similarly, the sale
of put options can also provide portfolio gains.

      If and to the extent authorized to do so, a NASL Portfolio may purchase
and sell call options on securities and on Eurodollar instruments that are
traded on U.S. and foreign securities exchanges and in the OTC markets, and on
securities indices, currencies and futures contracts. All calls sold by a NASL
Portfolio must be "covered" (that is, the NASL Portfolio must own the securities
or futures contract subject to the call) or must otherwise meet the asset
segregation requirements described below for so long as the call is outstanding.
Even though a NASL Portfolio will receive the option premium to help protect it
against loss, a call sold by the NASL Portfolio will expose the NASL Portfolio
during the term of the option to possible loss of opportunity to realize
appreciation in the market price of the underlying security or instrument and
may require the NASL Portfolio to hold a security or instrument that it might
otherwise have sold.

      Each NASL Portfolio reserves the right to invest in options on instruments
and indices which may be developed in the future to the extent consistent with
applicable law, the NASL Portfolio's investment objective and the restrictions
set forth herein.

      If and to the extent authorized to do so, a NASL Portfolio may purchase
and sell put options on securities (whether or not it holds the securities in
its portfolio) and on securities indices, currencies and futures contracts. A
NASL Portfolio will not sell put options if, as a result, more than 50% of the
NASL Portfolio's assets would be required to be segregated to cover its
potential obligations under put options other than those with respect to futures
contracts. In selling put options, a NASL Portfolio faces the risk that it may
be required to buy the underlying security at a disadvantageous price above the
market price.


GENERAL CHARACTERISTICS OF FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

      If and to the extent authorized to do so, a NASL Portfolio may trade
financial futures contracts or purchase or sell put and call options on those
contracts as a hedge against anticipated interest rate, currency or market
changes, for duration management and for risk management purposes. Futures
contracts are generally bought and sold on the commodities exchanges on which
they are listed with payment of initial and variation margin as described below.
The sale of a futures contract creates a firm obligation by a NASL Portfolio, as
seller, to deliver to the buyer the specific type of financial instrument called
for in the contract at a specific future time for a specified price (or, with
respect to certain instruments, the net cash amount). Options on futures
contracts are similar to options on securities except that an option on a
futures contract gives the purchaser the right, in return for the premium paid,
to assume a position in a futures contract and obligates the seller to deliver
that position.

   
      A NASL Portfolio's use of financial futures contracts and options thereon
will in all cases be consistent with applicable regulatory requirements and in
particular the rules and regulations of the CFTC and will be entered into only
for bona fide hedging or risk management purposes (including duration
management) or to attempt to increase income or gains. Maintaining a futures
contract or selling an option on a futures contract will typically require a
NASL Portfolio to deposit with a financial intermediary, as security for its
obligations, an amount of cash or other specified assets ("initial margin") that
initially is from 1% to 10% of the face amount of the contract (but may be
higher in some circumstances). Additional cash or assets
    

                                       -9-


<PAGE>   138


   
("variation margin") may be required to be deposited thereafter daily as the
mark-to-market value of the futures contract fluctuates. The purchase of an
option on a financial futures contract involves payment of a premium for the
option without any further obligation on the part of a NASL Portfolio. If a NASL
Portfolio exercises an option on a futures contract it will be obligated to post
initial margin (and potentially variation margin) for the resulting futures
position just as it would for any futures position. Futures contracts and
options thereon are generally settled by entering into an offsetting
transaction, but no assurance can be given that a position can be offset prior
to settlement or that delivery will occur.
    

   
      No NASL Portfolio will enter into a futures contract or option thereon if,
immediately thereafter, the sum of the amount of its initial margin and premiums
on open futures contracts and options thereon would exceed 5% of the current
fair market value of the NASL Portfolio's total assets; however, in the case of
an option that is in-the-money at the time of the purchase, the in-the-money
amount may be excluded in calculating the 5% limitation. The value of all
futures contracts sold by a NASL Portfolio (adjusted for the historical
volatility relationship between such NASL Portfolio and the contracts) will not
exceed the total market value of the NASL Portfolio's securities. The
segregation requirements with respect to futures contracts and options thereon
are described below under "Use of Segregated and Other Special Accounts".
    

OPTIONS ON SECURITIES INDICES AND OTHER FINANCIAL INDICES

      If and to the extent authorized to do so, a NASL Portfolio may purchase
and sell call and put options on securities indices and other financial indices.
In so doing, the NASL Portfolio can achieve many of the same objectives it would
achieve through the sale or purchase of options on individual securities or
other instruments. Options on securities indices and other financial indices are
similar to options on a security or other instrument except that, rather than
settling by physical delivery of the underlying instrument, options on indices
settle by cash settlement; that is, an option on an index gives the holder the
right to receive, upon exercise of the option, an amount of cash if the closing
level of the index upon which the option is based exceeds, in the case of a
call, or is less than, in the case of a put, the exercise price of the option
(except if, in the case of an OTC option, physical delivery is specified). This
amount of cash is equal to the excess of the closing price of the index over the
exercise price of the option, which also may be multiplied by a formula value.
The seller of the option is obligated, in return for the premium received, to
make delivery of this amount. The gain or loss on an option on an index depends
on price movements in the instruments comprising the market, market segment,
industry or other composite on which the underlying index is based, rather than
price movements in individual securities, as is the case with respect to options
on securities.


CURRENCY TRANSACTIONS

      If and to the extent authorized to do so, a NASL Portfolio may engage in
currency transactions with Counterparties to hedge the value of portfolio
securities denominated in particular currencies against fluctuations in relative
value. Currency transactions include currency forward contracts, exchange-listed
currency futures contracts and options thereon, exchange-listed and OTC options
on currencies, and currency swaps. A forward currency contract involves a
privately negotiated obligation to purchase or sell (with delivery generally
required) a specific currency at a future date, which may be any fixed number of
days from the date of the contract agreed upon by the parties, at a price set at
the time of the contract. A currency swap is an agreement to exchange cash flows
based on the notional difference among two or more currencies and operates
similarly to an interest rate swap, which is described below under "Swaps, Caps,
Floors and Collars". A NASL Portfolio may enter into currency transactions only
with Counterparties that are deemed creditworthy by its subadviser.

      A NASL Portfolio's dealings in forward currency contracts and other
currency transactions such as futures contracts, options, options on futures
contracts and swaps will be limited to hedging and other non-speculative
purposes, including transaction hedging and position hedging. Transaction
hedging is entering into a currency transaction with respect to specific assets
or liabilities of a NASL Portfolio, which will generally arise in connection
with the purchase or sale of the NASL Portfolio's portfolio securities or the
receipt of income from them. Position hedging is entering into a currency
transaction with respect to portfolio securities positions denominated or
generally quoted in that currency. A NASL Portfolio will not enter into a
transaction to hedge currency exposure to an extent greater, after netting all
transactions intended wholly or partially to offset other transactions, than the
aggregate market value (at the time of entering into the transaction) of the
securities held by the NASL Portfolio that are denominated or generally quoted
in or currently convertible into the currency, other than with respect to proxy
hedging as described below.

      A NASL Portfolio may cross-hedge currencies by entering into transactions
to purchase or sell one or more currencies that are expected to increase or
decline in value relative to other currencies to which the NASL Portfolio has or
in which the NASL Portfolio expects to have exposure. To reduce the effect of
currency fluctuations on the value of existing or anticipated

                                      -10-


<PAGE>   139



holdings of its securities, a NASL Portfolio may also engage in proxy hedging.
Proxy hedging is often used when the currency to which a NASL Portfolio's
holdings is exposed is difficult to hedge generally or difficult to hedge
against the dollar. Proxy hedging entails entering into a forward contract to
sell a currency, the changes in the value of which are generally considered to
be linked to a currency or currencies in which some or all of a NASL Portfolio's
securities are or are expected to be denominated, and to buy dollars. The amount
of the contract would not exceed the market value of the NASL Portfolio's
securities denominated in linked currencies.

      Currency transactions are subject to risks different from other portfolio
transactions, as discussed below under "Risk Factors". If a NASL Portfolio
enters into a currency hedging transaction, the NASL Portfolio will comply with
the asset segregation requirements described below under "Use of Segregated and
Other Special Accounts".


COMBINED TRANSACTIONS

      If and to the extent authorized to do so, a NASL Portfolio may enter into
multiple transactions, including multiple options transactions, multiple futures
transactions, multiple currency transactions (including forward currency
contracts), multiple interest rate transactions and any combination of futures,
options, currency and interest rate transactions, instead of a single Hedging
and Other Strategic Transaction, as part of a single or combined strategy when,
in the judgment of the subadviser, it is in the best interests of the NASL
Portfolio to do so. A combined transaction will usually contain elements of risk
that are present in each of its component transactions. Although combined
transactions will normally be entered into by a NASL Portfolio based on the
subadviser's judgment that the combined strategies will reduce risk or otherwise
more effectively achieve the desired portfolio management goal, it is possible
that the combination will instead increase the risks or hinder achievement of
the portfolio management objective.


SWAPS, CAPS, FLOORS AND COLLARS

      Among the Hedging and Other Strategic Transactions into which a NASL
Portfolio may be authorized to enter are interest rate, currency and index
swaps, the purchase or sale of related caps, floors and collars and other
derivatives. A NASL Portfolio will enter into these transactions primarily to
seek to preserve a return or spread on a particular investment or portion of its
portfolio, to protect against currency fluctuations, as a duration management
technique or to protect against any increase in the price of securities a NASL
Portfolio anticipates purchasing at a later date. A NASL Portfolio will use
these transactions for non-speculative purposes and will not sell interest rate
caps or floors if it does not own securities or other instruments providing the
income the NASL Portfolio may be obligated to pay. Interest rate swaps involve
the exchange by a NASL Portfolio with another party of their respective
commitments to pay or receive interest (for example, an exchange of floating
rate payments for fixed rate payments with respect to a notional amount of
principal). A currency swap is an agreement to exchange cash flows on a notional
amount based on changes in the values of the reference indices. The purchase of
a cap entitles the purchaser to receive payments on a notional principal amount
from the party selling the cap to the extent that a specified index exceeds a
predetermined interest rate. The purchase of an interest rate floor entitles the
purchaser to receive payments of interest on a notional principal amount from
the party selling the interest rate floor to the extent that a specified index
falls below a predetermined interest rate or amount. The purchase of a floor
entitles the purchaser to receive payments on a notional principal amount from
the party selling the floor to the extent that a specific index falls below a
predetermined interest rate or amount. A collar is a combination of a cap and a
floor that preserves a certain return with a predetermined range of interest
rates or values.

      A NASL Portfolio will usually enter into interest rate swaps on a net
basis, that is, two payment streams are netted out in a cash settlement on the
payment date or dates specified in the instrument, with the NASL Portfolio
receiving or paying, as the case may be, only the net amount of the two
payments. Inasmuch as these swaps, caps, floors, collars and other similar
derivatives are entered into for good faith hedging or other non-speculative
purposes, they do not constitute senior securities under the Investment Company
Act of 1940, as amended, and, thus, will not be treated as being subject to the
NASL Portfolio's borrowing restrictions. A NASL Portfolio will not enter into
any swap, cap, floor, collar or other derivative transaction unless the
Counterparty is deemed creditworthy by the subadviser. If a Counterparty
defaults, a NASL Portfolio may have contractual remedies pursuant to the
agreements related to the transaction. The swap market has grown substantially
in recent years with a large number of banks and investment banking firms acting
both as principals and as agents utilizing standardized swap documentation. As a
result, the swap market has become relatively liquid. Caps, floors and collars
are more recent innovations for which standardized documentation has not yet
been fully developed and, for that reason, they are less liquid than swaps.

                                      -11-


<PAGE>   140



      The liquidity of swap agreements will be determined by a subadviser based
on various factors, including (1) the frequency of trades and quotations, (2)
the number of dealers and prospective purchasers in the marketplace, (3) dealer
undertakings to make a market, (4) the nature of the security (including any
demand or tender features), and (5) the nature of the marketplace for trades
(including the ability to assign or offset a NASL Portfolio's rights and
obligations relating to the investment). Such determination will govern whether
a swap will be deemed to be within the 15% restriction on investments in
securities that are not readily marketable.

      Each NASL Portfolio will maintain cash and appropriate liquid assets in a
segregated custodial account to cover its current obligations under swap
agreements. If a NASL Portfolio enters into a swap agreement on a net basis, it
will segregate assets with a daily value at least equal to the excess, if any,
of the NASL Portfolio's accrued obligations under the swap agreement over the
accrued amount the NASL Portfolio is entitled to receive under the agreement. If
a NASL Portfolio enters into a swap agreement on other than a net basis, it will
segregate assets with a value equal to the full amount of the NASL Portfolio's
accrued obligations under the agreement. See also, "Use of Segregated and Other
Special Accounts."


EURODOLLAR INSTRUMENTS

      If and to the extent authorized to do so, a NASL Portfolio may make
investments in Eurodollar instruments, which are typically dollar-denominated
futures contracts or options on those contracts that are linked to the London
Interbank Offered Rate ("LIBOR"), although foreign currency denominated
instruments are available from time to time. Eurodollar futures contracts enable
purchasers to obtain a fixed rate for the lending of funds and sellers to obtain
a fixed rate for borrowings. A NASL Portfolio might use Eurodollar futures
contracts and options thereon to hedge against changes in LIBOR, to which many
interest rate swaps and fixed income instruments are linked.


RISK FACTORS

      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. Use
of put and call options could result in losses to a NASL Portfolio, force the
sale or purchase of portfolio securities at inopportune times or for prices
higher than (in the case of put options) or lower than (in the case of call
options) current market values, or cause a NASL Portfolio to hold a security it
might otherwise sell.

      The use of futures and options transactions entails certain special risks.
In particular, the variable degree of correlation between price movements of
futures contracts and price movements in the related securities position of a
NASL Portfolio could create the possibility that losses on the hedging
instrument are greater than gains in the value of the NASL Portfolio's position.
In addition, futures and options markets could be illiquid in some circumstances
and certain over-the-counter options could have no markets. As a result, in
certain markets, a NASL Portfolio might not be able to close out a transaction
without incurring substantial losses. Although a NASL Portfolio's use of futures
and options transactions for hedging should tend to minimize the risk of loss
due to a decline in the value of the hedged position, at the same time it will
tend to limit any potential gain to a NASL Portfolio that might result from an
increase in value of the position. Finally, the daily variation margin
requirements for futures contracts create a greater ongoing potential financial
risk than would purchases of options, in which case the exposure is limited to
the cost of the initial premium.

      Currency hedging involves some of the same risks and considerations as
other transactions with similar instruments. Currency transactions can result in
losses to a NASL Portfolio if the currency being hedged fluctuates in value to a
degree or in a direction that is not anticipated. Further, the risk exists that
the perceived linkage between various currencies may not be present or may not
be present during the particular time that a NASL Portfolio is engaging in proxy
hedging. Currency transactions are also subject to risks different from those of
other portfolio transactions. Because currency control is of great importance to
the issuing governments and influences economic planning and policy, purchases
and sales of currency and related instruments can be adversely affected by
government exchange controls, limitations or restrictions on repatriation of
currency, and manipulations or exchange restrictions imposed by governments.
These forms of governmental actions can result in losses to a NASL Portfolio if
it is unable to deliver or receive currency or monies in settlement of
obligations and could also cause hedges it has entered into to be rendered
useless, resulting in full currency exposure as well as incurring transaction
costs. Buyers and sellers of currency futures contracts are subject to the same
risks that apply to the use of futures contracts generally. Further, settlement
of a currency futures contract for the purchase of most currencies must occur at
a bank based in the issuing nation. Trading options on currency futures
contracts is relatively new, and the ability to establish and close

                                      -12-


<PAGE>   141



out positions on these options is subject to the maintenance of a liquid market
that may not always be available. Currency exchange rates may fluctuate based on
factors extrinsic to that country's economy.

      Losses resulting from the use of Hedging and Other Strategic Transactions
will reduce a NASL Portfolio's net asset value, and possibly income, and the
losses can be greater than if Hedging and Other Strategic Transactions had not
been used.


RISKS OF HEDGING AND OTHER STRATEGIC TRANSACTIONS OUTSIDE THE UNITED STATES

      When conducted outside the United States, Hedging and Other Strategic
Transactions may not be regulated as rigorously as in the United States, may not
involve a clearing mechanism and related guarantees, and will be subject to the
risk of governmental actions affecting trading in, or the prices of, foreign
securities, currencies and other instruments. The value of positions taken as
part of non-U.S. Hedging and Other Strategic Transactions also could be
adversely affected by: (1) other complex foreign political, legal and economic
factors, (2) lesser availability of data on which to make trading decisions than
in the United States, (3) delays in a NASL Portfolio's ability to act upon
economic events occurring in foreign markets during non-business hours in the
United States, (4) the imposition of different exercise and settlement terms and
procedures and margin requirements than in the United States and (5) lower
trading volume and liquidity.


USE OF SEGREGATED AND OTHER SPECIAL ACCOUNTS

      Use of many Hedging and Other Strategic Transactions by a NASL Portfolio
will require, among other things, that the NASL Portfolio segregate cash, liquid
high grade debt obligations or other assets with its custodian, or a designated
sub-custodian, to the extent the NASL Portfolio's obligations are not otherwise
"covered" through ownership of the underlying security, financial instrument or
currency. In general, either the full amount of any obligation by a NASL
Portfolio to pay or deliver securities or assets must be covered at all times by
the securities, instruments or currency required to be delivered, or, subject to
any regulatory restrictions, an amount of cash or liquid high grade debt
obligations at least equal to the current amount of the obligation must be
segregated with the custodian or sub-custodian. The segregated assets cannot be
sold or transferred unless equivalent assets are substituted in their place or
it is no longer necessary to segregate them. A call option on securities written
by a NASL Portfolio, for example, will require the NASL Portfolio to hold the
securities subject to the call (or securities convertible into the needed
securities without additional consideration) or to segregate liquid high grade
debt obligations sufficient to purchase and deliver the securities if the call
is exercised. A call option sold by a NASL Portfolio on an index will require
the NASL Portfolio to own portfolio securities that correlate with the index or
to segregate liquid high grade debt obligations equal to the excess of the index
value over the exercise price on a current basis. A put option on securities
written by a NASL Portfolio will require the NASL Portfolio to segregate liquid
high grade debt obligations equal to the exercise price. Except when a NASL
Portfolio enters into a forward contract in connection with the purchase or sale
of a security denominated in a foreign currency or for other non-speculative
purposes, which requires no segregation, a currency contract that obligates the
NASL Portfolio to buy or sell a foreign currency will generally require the NASL
Portfolio to hold an amount of that currency or liquid securities denominated in
that currency equal to a NASL Portfolio's obligations or to segregate liquid
high grade debt obligations equal to the amount of the NASL Portfolio's
obligations.

      OTC options entered into by a NASL Portfolio, including those on
securities, currency, financial instruments or indices, and OCC-issued and
exchange-listed index options will generally provide for cash settlement,
although a NASL Portfolio will not be required to do so. As a result, when a
NASL Portfolio sells these instruments it will segregate an amount of assets
equal to its obligations under the options. OCC-issued and exchange-listed
options sold by a NASL Portfolio other than those described above generally
settle with physical delivery, and the NASL Portfolio will segregate an amount
of assets equal to the full value of the option. OTC options settling with
physical delivery or with an election of either physical delivery or cash
settlement will be treated the same as other options settling with physical
delivery.

      In the case of a futures contract or an option on a futures contract, a
NASL Portfolio must deposit initial margin and, in some instances, daily
variation margin in addition to segregating assets sufficient to meet its
obligations to purchase or provide securities or currencies, or to pay the
amount owed at the expiration of an index-based futures contract. These assets
may consist of cash, cash equivalents, liquid debt or equity securities or other
acceptable assets. A NASL Portfolio will accrue the net amount of the excess, if
any, of its obligations relating to swaps over its entitlements with respect to
each swap on a daily basis and will segregate with its custodian, or designated
sub-custodian, an amount of cash or liquid high grade debt obligations having an
aggregate value equal to at least the accrued excess. Caps, floors and collars
require segregation of assets with a value equal to a NASL Portfolio's net
obligation, if any.

                                      -13-


<PAGE>   142



      Hedging and Other Strategic Transactions may be covered by means other
than those described above when consistent with applicable regulatory policies.
A NASL Portfolio may also enter into offsetting transactions so that its
combined position, coupled with any segregated assets, equals its net
outstanding obligation in related options and Hedging and Other Strategic
Transactions. A NASL Portfolio could purchase a put option, for example, if the
strike price of that option is the same or higher than the strike price of a put
option sold by the NASL Portfolio. Moreover, instead of segregating assets if it
holds a futures contracts or forward contract, a NASL Portfolio could purchase a
put option on the same futures contract or forward contract with a strike price
as high or higher than the price of the contract held. Other Hedging and Other
Strategic Transactions may also be offset in combinations. If the offsetting
transaction terminates at the time of or after the primary transaction, no
segregation is required, but if it terminates prior to that time, assets equal
to any remaining obligation would need to be segregated.


OTHER LIMITATIONS

      No NASL Portfolio will maintain open short positions in futures contracts,
call options written on futures contracts, and call options written on
securities indices if, in the aggregate, the current market value of the open
positions exceeds the current market value of that portion of its securities
portfolio being hedged by those futures and options plus or minus the unrealized
gain or loss on those open positions, adjusted for the historical volatility
relationship between that portion of the portfolio and the contracts (e.g., the
Beta volatility factor). For purposes of the limitation stated in the
immediately preceding sentence, to the extent the NASL Portfolio has written
call options on specific securities in that portion of its portfolio, the value
of those securities will be deducted from the current market value of that
portion of the securities portfolio. If this limitation should be exceeded at
any time, the NASL Portfolio will take prompt action to close out the
appropriate number of open short positions to bring its open futures and options
positions within this limitation.

      The degree to which a NASL Portfolio may utilize Hedging and Other
Strategic Transactions may also be affected by certain provisions of the
Internal Revenue Code of 1986, as amended.


                             INVESTMENT RESTRICTIONS

      There are two classes of investment restrictions to which NASL is subject
in implementing the investment policies of the NASL Portfolios: fundamental and
nonfundamental. Nonfundamental restrictions are subject to change by the NASL
Board without shareholder approval. Fundamental restrictions may only be changed
by a vote of the lesser of (i) 67% or more of the shares represented at a
meeting at which more than 50% of the outstanding shares are represented or (ii)
more than 50% of the outstanding shares.

      With respect to the submission of a change in an investment restriction to
the holders of NASL's outstanding voting securities, the matter shall be deemed
to have been effectively acted upon with respect to a particular NASL Portfolio
if a majority of the outstanding voting securities of the NASL Portfolio vote
for the approval of the matter, notwithstanding (1) that the matter has not been
approved by the holders of a majority of the outstanding voting securities of
any other NASL Portfolio affected by the matter, and (2) that the matter has not
been approved by the vote of a majority of the outstanding voting securities of
NASL.

      All of the restrictions through restriction 8. are fundamental.
Restrictions 9. through 15. are nonfundamental.


FUNDAMENTAL

      NASL may not issue senior securities, except to the extent that the
borrowing of money in accordance with restriction 3. may constitute the issuance
of a senior security. (For purposes of this restriction, purchasing securities
on a when-issued or delayed delivery basis and engaging in Hedging and Other
Strategic Transactions will not be deemed to constitute the issuance of a senior
security.) In addition, unless a NASL Portfolio is specifically excepted by the
terms of a restriction, each NASL Portfolio will not:

(1)   Invest more than 25% of the value of its total assets in securities of
      issuers having their principal activities in any particular industry,
      excluding United States Government securities and obligations of domestic
      branches of U.S. banks and savings and loan associations, except that this
      restriction shall not apply to the NASL Real Estate Securities Trust.
      [NASL has determined to forego the exclusion from the above policy of
      obligations of domestic branches of U.S. savings and loan associations and
      to limit the exclusion of obligations of domestic branches of U.S. banks
      to the NASL Money Market Trust.] For purposes of this restriction, neither
      finance companies as a group nor utility companies as

                                      -14-


<PAGE>   143



      a group are considered to be a single industry. Such companies will be
      grouped instead according to their services; for example, gas, electric
      and telephone utilities will each be considered a separate industry. Also
      for purposes of this restriction, foreign government issuers and
      supranational issuers are not considered members of any industry.

(2)   Purchase the securities of any issuer if the purchase would cause more
      than 5% of the value of the NASL Portfolio's total assets to be invested
      in the securities of any one issuer (excluding United States Government
      securities) or cause more than 10% of the voting securities of the issuer
      to be held by the NASL Portfolio, except that up to 25% of the value of
      each NASL Portfolio's total assets may be invested without regard to these
      restrictions. The NASL Emerging Growth Trust is not subject to these
      restrictions.

(3)   Borrow money, except that each NASL Portfolio may borrow (i) for temporary
      or emergency purposes (not for leveraging) up to 33 1/3% of the value of
      the NASL Portfolio's total assets (including amounts borrowed) less
      liabilities (other than borrowings) and (ii) in connection with reverse
      repurchase agreements, mortgage dollar rolls and other similar
      transactions.

(4)   Underwrite securities of other issuers except insofar as NASL may be
      considered an underwriter under the Securities Act of 1933 in selling
      portfolio securities.

(5)   Purchase or sell real estate, except that each NASL Portfolio may invest
      in securities issued by companies which invest in real estate or interests
      therein and each of the NASL Portfolios other than the NASL Money Market
      Trust may invest in mortgages and mortgage backed securities.

(6)   Purchase or sell commodities or commodity contracts except that each NASL
      Portfolio other than the NASL Money Market Trust may purchase and sell
      futures contracts on financial instruments and indices and options on such
      futures contracts and each NASL Portfolio other than the NASL Money Market
      Trust may purchase and sell futures contracts on foreign currencies and
      options on such futures contracts.

(7)   Lend money to other persons except by the purchase of obligations in which
      the NASL Portfolio is authorized to invest and by entering into repurchase
      agreements. For purposes of this restriction, collateral arrangements with
      respect to options, forward currency and futures transactions will not be
      deemed to involve the lending of money.

(8)   Lend securities in excess of 33 1/3% of the value of its total assets. For
      purposes of this restriction, collateral arrangements with respect to
      options, forward currency and futures transactions will not be deemed to
      involve loans of securities.


NONFUNDAMENTAL

(9)   Knowingly invest more than 15% of the value of its net assets in
      securities or other investments, including repurchase agreements maturing
      in more than seven days but excluding master demand notes, that are not
      readily marketable, except that the NASL Money Market Trust may not invest
      in excess of 10% of its net assets in such securities or other
      investments.

(10)  Sell securities short or purchase securities on margin except that it may
      obtain such short-term credits as may be required to clear transactions.
      For purposes of this restriction, collateral arrangements with respect to
      Hedging and Other Strategic Transactions will not be deemed to involve the
      use of margin.

(11)  Write or purchase options on securities, financial indices or currencies
      except to the extent a NASL Portfolio is specifically authorized to engage
      in Hedging and Other Strategic Transactions.

(12)  Purchase securities for the purpose of exercising control or management.

(13)  Purchase securities of other investment companies if the purchase would
      cause more than 10% of the value of the NASL Portfolio's total assets to
      be invested in investment company securities, provided that (i) no
      investment will be made in the securities of any one investment company if
      immediately after such investment more than 3% of the outstanding voting
      securities of such company would be owned by the NASL Portfolio or more
      than 5% of the value of the NASL Portfolio's total assets would be
      invested in such company and (ii) no restrictions shall apply to a
      purchase of investment company securities in connection with a merger,
      consolidation or reorganization or in connection with the investment of
      collateral received in connection with the lending of securities in the
      Navigator Securities Lending Trust. For purposes of this restriction,
      privately issued collateralized mortgage obligations will not be treated
      as investment company securities if issued by "Exemptive Issuers".
      Exemptive Issuers are defined as unmanaged, fixed-asset issuers that (a)

                                      -15-


<PAGE>   144



      invest primarily in mortgage-backed securities, (b) do not issue
      redeemable securities as defined in section 2(a)(32) of the Investment
      Company Act of 1940, (c) operate under general exemptive orders exempting
      them from "all provisions of the Investment Company Act of 1940," and (d)
      are not registered or regulated under the Investment Company Act of 1940
      as investment companies.

(14)  Pledge, hypothecate, mortgage or transfer (except as provided in
      restriction 8.) as security for indebtedness any securities held by the
      NASL Portfolio except in an amount of not more than 10% (33 1/3% in the
      case of the NASL International Stock Trust and 15% in the case of the NASL
      Balanced Trust) of the value of the NASL Portfolio's total assets and then
      only to secure borrowings permitted by restrictions 3. and 10. For
      purposes of this restriction, collateral arrangements with respect to
      Hedging and Other Strategic Transactions will not be deemed to involve a
      pledge of assets.

(15)  Purchase securities of foreign issuers, except that (A) each NASL
      Portfolio may invest up to 20% of its total assets in such securities (in
      the case of the NASL Balanced Trust, the applicable percentage limit is
      30% of its total assets and ADRs and U.S. dollar-denominated securities
      are not included in the applicable percentage limit); and (B) the
      foregoing restriction shall not apply to the NASL Pacific Rim Emerging
      Markets, NASL International Stock, NASL Capital Growth Bond, NASL Real
      Estate Securities and NASL Common Stock Trusts.

      In addition to the above policies, the NASL Money Market Trust is subject
to certain restrictions required by Rule 2a-7 under the Investment Company Act
of 1940. In order to comply with such restrictions, the NASL Money Market Trust
will, inter alia, 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, or (iii) more than the greater of $1 million or
1% of its total assets to be invested in the second tier securities of that
issuer.

      If a percentage restriction is adhered to at the time of an investment, a
later increase or decrease in the investment's percentage of the value of a NASL
Portfolio's total assets resulting from a change in such values or assets will
not constitute a violation of the percentage restriction, except in the case of
the NASL Money Market Trust where the percentage limitation of restriction 9.
must be met at all times.


                               PORTFOLIO TURNOVER

      The annual rate of portfolio turnover will normally differ for each NASL
Portfolio and may vary from year to year. Portfolio turnover is calculated by
dividing the lesser of purchases or sales of portfolio securities during the
fiscal year by the monthly average of the value of the NASL Portfolio's
securities (excluding from the computation all securities, including options,
with maturities at the time of acquisition of one year or less). A high rate of
portfolio turnover generally involves correspondingly greater brokerage
commission expenses, which must be borne directly by the NASL Portfolio. No
portfolio turnover rate can be calculated for the NASL Money Market Trust due to
the short maturities of the instruments purchased. The portfolio turnover rate
may vary from year to year, as well as within a year. High portfolio turnover
rates (100% or more) can result in corresponding increases in brokerage
commissions for the NASL Portfolio. Anticipated portfolio turnover rates (based
on normal circumstances) for the other NASL Portfolios are not expected to
exceed 200%.

      Estimated rates are not a limiting factor when it is deemed appropriate to
purchase or sell securities for a NASL Portfolio. Each NASL Portfolio intends to
comply with the various requirements of the Internal Revenue Code so as to
qualify as a "regulated investment company" thereunder. One such requirement is
that a portfolio must derive less than 30% of its gross income from the sale or
other disposition of stock or securities held for less than three months.
Accordingly, the ability of a particular NASL Portfolio to effect certain
portfolio transactions may be limited.

                       INVESTMENT MANAGEMENT ARRANGEMENTS

      The following information supplements the material appearing in the
Prospectus/Proxy Statement under the caption "Additional Information About
NASL--C. Management." Copies of the Advisory and Subadvisory Agreements
discussed below have been filed with and are available from the Securities and
Exchange Commission.

      NASL, formerly a Maryland corporation known as "NASL Series Fund, Inc."
(the "Fund"), was reorganized as a Massachusetts business trust effective
December 31, 1988. Pursuant to such reorganization, NASL assumed all the assets
and liabilities of the Fund and carried on its business and operations with the
same investment management arrangements as were in effect for the Fund at the
time of the reorganization. The assets and liabilities of each of the Fund's
separate portfolios were assumed by the corresponding portfolios of NASL.

      NASL Financial is a Massachusetts corporation whose principal offices are
located at 116 Huntington Avenue, Boston, Massachusetts 02116. NASL Financial is
registered as an investment adviser under the Investment Advisers Act of 1940
and as a broker-dealer under the Securities Exchange Act of 1934. It is a member
of the National Association of Securities Dealers, Inc. (the "NASD"). In
addition, NASL Financial serves as principal underwriter of certain contracts
issued by Security Life.

      The Advisory Agreement was approved by the NASL Board on September 28,
1995 and by the shareholders of the then existing portfolios of NASL on December
5, 1995. These approvals occurred in connection with the change of control of
NASL Financial as a result of the merger of North American Life Assurance
Company, the ultimate controlling parent of NASL Financial, with The
Manufacturers Life Insurance Company on January 1, 1996.

      On September 27, 1996, the NASL Board appointed Manufacturers Adviser
Corporation ("MAC") pursuant to a new Subadvisory Agreement with MAC ("MAC
Subadvisory Agreement") to manage the NASL Money Market Trust. Such Subadvisory
Agreement was approved by the NASL Board, including a majority of the Trustees
who are not parties to the agreements or interested persons of any party to such
agreements, on September 27 (with an effective date of October 1, 1996) and has
been submitted for ratification by the shareholders of the NASL Money Market
Trust, as described in the Prospectus/Proxy Statement. Also on September 27,
1996, the NASL Board (i) appointed Rowe Price-Fleming International, Inc.
("Price-Fleming") pursuant to a new Subadvisory Agreement with Price-Fleming
("Price-Fleming Subadvisory Agreement") to manage the NASL International Stock
Trust, (ii) appointed Founders Asset Management, Inc. ("Founders") pursuant to
an amendment to its existing Subadvisory Agreement with respect to other
portfolios of NASL ("Founders Subadvisory Agreement") to also manage the NASL
Balanced Trust, (iii) appointed MAC pursuant to the MAC Subadvisory Agreement to
also manage the NASL Pacific Rim Emerging Markets, NASL Real Estate Securities,
NASL Common Stock, NASL Capital Growth Bond and NASL Equity Index Trusts and
(iv) Warburg, Pincus Counsellors, Inc. ("Warburg Pincus") pursuant to a new
Subadvisory Agreement with Warburg Pincus ("Warburg Pincus Subadvisory
Agreement") to manage the NASL Emerging Growth Trust. Such Subadvisory
Agreements or amended Subadvisory Agreement and amendments to the Advisory
Agreement, to provide for the management of the newly-established portfolios,
were approved by the NASL Board, including a majority of the Trustees who are
not parties to the agreements or interested persons of any party to such
agreements on September 27, 1996.


THE ADVISORY AGREEMENT

      Under the terms of the Advisory Agreement, NASL Financial administers the
business and affairs of NASL. NASL Financial is responsible for performing or
paying for various administrative services for NASL, including providing at NASL
Financial's expense (i) office space and all necessary office facilities and
equipment, (ii) necessary executive and other personnel for managing the affairs
of NASL and for performing certain clerical, accounting and other office
functions, and (iii) all other information and services, other than services of
counsel, independent accountants or investment subadvisory services provided by
any subadviser under a subadvisory agreement, required in connection with the
preparation of all tax returns and documents required to comply with the federal
securities laws. NASL Financial pays the cost of any advertising or sales
literature relating solely to NASL, the cost of printing and mailing
prospectuses to persons other than current holders of NASL shares or of variable
contracts funded by NASL shares and the compensation of NASL's officers and
Trustees that are officers, directors or employees of NASL Financial or its
affiliates. In addition, advisory fees are reduced or NASL Financial reimburses
NASL if the total of all expenses (excluding advisory fees, taxes, portfolio
brokerage commissions, interest, litigation and indemnification expenses and
other extraordinary expenses not incurred in the ordinary course of NASL's
business) applicable to a NASL Portfolio exceeds an annual rate of .75% in the
case of the NASL International Stock Trust and NASL Pacific Rim Emerging Markets
Trust or .50% in the case of all other NASL Portfolios of the average net asset
value of such NASL Portfolio. The expense limitation will continue in effect
from year to year unless otherwise terminated at any year end by NASL Financial
on 30 days' notice to NASL.

      In addition to providing the services and expense limitation described
above, NASL Financial selects, contracts with and compensates subadvisers to
manage the investment and reinvestment of the assets of the NASL Portfolios.
NASL Financial

                                      -19-

monitors the compliance of such subadvisers with the investment objectives and
related policies of each NASL Portfolio and reviews the performance of such
subadvisers and reports periodically on such performance to the NASL Board.

      As compensation for its services, NASL Financial receives a fee from NASL
computed separately for each NASL Portfolio. The fee for each NASL Portfolio is
stated as an annual percentage of the current value of the net assets of such
NASL Portfolio, and is possible at the rate set forth in the Prospectus/Proxy
Statement. The fee, which is accrued daily and payable monthly, is calculated
for each day by multiplying the daily equivalent of the annual percentage
prescribed for a NASL Portfolio by the value of its net assets at the close of
business on the previous business day of NASL.

   
      For the years ended December 31, 1995, 1994 and 1993 the aggregate
investment advisory fee payable by NASL under the fee schedule then in effect
for the then-existing portfolios of NASL, absent the expense limitation
provision, was $33,808,255, $27,076,438 and $16,988,737, respectively. Of such
amounts, $1,318,573, $1,158,400, and $606,603 was paid on behalf of the NASL 
Money Market Trust in such years, respectively. For the six month period ended
June 30, 1996, see the Prospectus/Proxy Statement.
    


THE SUBADVISORY AGREEMENTS

      Under the terms of each of the current subadvisory agreements
(collectively "Subadvisory Agreements"), the subadviser manages the investment
and reinvestment of the assets of the assigned NASL Portfolios, subject to the
supervision of the NASL Board. The subadviser formulates a continuous investment
program for each such NASL Portfolio consistent with its investment objectives
and policies outlined in the Prospectus/Proxy Statement. Each subadviser
implements such programs by purchases and sales of securities and regularly
reports to NASL Financial and the NASL Board with respect to the implementation
of such programs. Each subadviser, at its expense, furnishes all necessary
investment and management facilities, including salaries of personnel required
for it to execute its duties, as well as administrative facilities, including
bookkeeping, clerical personnel, and equipment necessary for the conduct of the
investment affairs of the assigned NASL Portfolios.

      As compensation for their services, the subadvisers receive fees from NASL
Financial computed separately for each NASL Portfolio. The fee for each NASL
Portfolio is stated as an annual percentage of the current value of the net
assets of the NASL Portfolio, and is payable at the rate set forth in the
Prospectus/Proxy Statement. The fees are calculated on the basis of the average
of all valuations of net assets of each NASL Portfolio made at the close of
business on each business day of NASL during the period for which such fees are
paid. Once the average net assets of a NASL Portfolio exceed amounts specified
in the Prospectus/Proxy Statement, the fee is reduced with respect to such
excess.

      For the years ended December 31, 1995, 1994 and 1993, NASL Financial paid
aggregate subadvisory fees of $12,007,940 $9,905,072, and $6,285,555,
respectively. Of such amounts $197,786, $173,760 and $90,990 was paid on behalf
of the NASL Money Market Trust (to its previous subadviser) in such years,
respectively. For the six month period ended June 30, 1996, see the
Prospectus/Proxy Statement.

      Subject to the expense limitations discussed above, NASL is responsible
for the payment of all expenses of its organization, operations and business,
except those which NASL Financial or subadvisers have agreed to pay pursuant to
the Advisory or Subadvisory Agreements. Expenses borne by NASL include charges
and expenses of the custodian, independent accountants and transfer, bookkeeping
and dividend disbursing agent appointed by NASL; brokers' commissions and issue
and transfer taxes on securities transactions to which NASL is a party; taxes
and fees payable by NASL; and legal fees and expenses in connection with the
affairs of NASL, including registering and qualifying its shares with regulatory
authorities and in connection with any litigation.

      The Advisory Agreement and each Subadvisory Agreement will continue in
effect as to a NASL Portfolio for a period no more than two years from the date
of its execution or the execution of an amendment making the agreement
applicable to that NASL Portfolio only so long as such continuance is
specifically approved at least annually either by the NASL Board or by the vote
of a majority of the outstanding voting securities of NASL, provided that in
either event such continuance shall also be approved by the vote of the majority
of the Trustees who are not interested persons of any party to the Agreements,
cast in person at a meeting called for the purpose of voting on such approval.
The required shareholder approval of any continuance of any of the Agreements
shall be effective with respect to any NASL Portfolio if a majority of the
outstanding voting securities of the series of shares of beneficial interest of
that NASL Portfolio vote to approve such continuance, notwithstanding that such
continuance may not have been approved by a majority of the outstanding voting
securities of (i) any other NASL Portfolio affected by the Agreement or (ii) all
of the portfolios of NASL.

                                      -20-


<PAGE>   149



      If the holders of any series of shares of beneficial interest of any NASL
Portfolio fail to approve any continuance of the Advisory Agreement or the
Subadvisory Agreement, NASL Financial or the subadviser will continue to act as
investment adviser or subadviser with respect to such NASL Portfolio pending the
required approval of the continuance of such Agreement, of a new contract with
NASL Financial or the subadviser or different adviser or subadviser, or other
definitive action. In the case of NASL Financial, the compensation received in
respect of such a NASL Portfolio during such period will be no more than its
actual costs incurred in furnishing investment advisory and management services
to such NASL Portfolio or the amount it would have received under the Advisory
Agreement in respect of such NASL Portfolio, whichever is less. In the case of
the subadvisers, the compensation received in respect of such a NASL Portfolio
during such period will be no more than that permitted by Rule 15a-4 under the
Investment Company Act of 1940.

      The Advisory Agreement and the Subadvisory Agreements may be terminated at
any time without the payment of any penalty on 60 days' written notice to the
other party or parties to the Agreements, and to NASL in the case of the
Subadvisory Agreements, (i) by the NASL Board; (ii) by the vote of a majority of
the outstanding voting securities of NASL, or with respect to any NASL
Portfolio, by the vote of a majority of the outstanding voting securities of the
series of shares of beneficial interest of such NASL Portfolio; and (iii) by
NASL Financial, and in the case of the Subadvisory Agreements, by the respective
subadvisers. The Agreements will automatically terminate in the event of their
assignment.

      The Advisory Agreement may be amended by NASL and NASL Financial and the
Subadvisory Agreements by NASL Financial and respective subadvisers provided
such amendment is specifically approved by the vote of a majority of the
outstanding voting securities of NASL and by the vote of a majority of the
Trustees of NASL who are not interested persons of NASL, NASL Financial or the
applicable subadviser cast in person at a meeting called for the purpose of
voting on such approval. The required shareholder approval of any amendment
shall be effective with respect to any NASL Portfolio if a majority of the
outstanding voting securities of that NASL Portfolio vote to approve the
amendment, notwithstanding that the amendment may not have been approved by a
majority of the outstanding voting securities of (i) any other NASL portfolio
affected by the amendment or (ii) all the portfolios of NASL. Shareholder
approval with respect to certain subadvisory changes will no longer be required
if the manager of managers proposal described in the Prospectus/Proxy Statement
is approved. See "Additional Information About NASL-C. Management of NASL."


                               PORTFOLIO BROKERAGE

      Pursuant to the Subadvisory Agreements, the subadvisers are responsible
for placing all orders for the purchase and sale of portfolio securities of
NASL. The subadvisers have no formula for the distribution of NASL's brokerage
business, their intention being to place orders for the purchase and sale of
securities with the primary objective of obtaining the most favorable overall
results for NASL. The cost of securities transactions for each NASL Portfolio
will consist primarily of brokerage commissions or dealer or underwriter
spreads. Bonds and money market instruments are generally traded on a net basis
and do not normally involve either brokerage commissions or transfer taxes.

      Occasionally, securities may be purchased directly from the issuer. For
securities traded primarily in the over-the-counter market, the subadvisers
will, where possible, deal directly with dealers who make a market in the
securities unless better prices and execution are available elsewhere. Such
dealers usually act as principals for their own account.

      In selecting brokers or dealers through whom to effect transactions, the
subadvisers will give consideration to a number of factors, including price,
dealer spread or commission, if any, the reliability, integrity and financial
condition of the broker-dealer, size of the transaction and difficulty of
execution. Consideration of these factors by a subadviser, either in terms of a
particular transaction or the subadviser's overall responsibilities with respect
to NASL and any other accounts managed by the subadviser, could result in NASL
paying a commission or spread on a transaction that is in excess of the amount
of commission or spread another broker-dealer might have charged for executing
the same transaction. In selecting brokers and dealers, the subadvisers will
also give consideration to the value and quality of any research, statistical,
quotation or valuation services provided by the broker or dealer. In placing a
purchase or sale order, a subadviser may use a broker whose commission in
effecting the transaction is higher than that of some other broker if the
subadviser determines in good faith that the amount of the higher commission is
reasonable in relation to the value of the brokerage and research services
provided by such broker, viewed in terms of either the particular transaction or
the subadviser's overall responsibilities with respect to NASL and any other
accounts managed by the subadviser. Brokerage and research services provided by
brokers and dealers include advice, either directly or through publications or
writings, as to the value of securities, the advisability of purchasing or
selling securities, the availability of securities or purchasers or sellers of
securities, and analyses and reports concerning issuers, industries, securities,
economic factors and trends and portfolio strategy. Consistent with the
foregoing considerations and the Rules of Fair Practice of the NASD, sales of
contracts for which the broker-dealer or an affiliate thereof is responsible

                                      -21-


<PAGE>   150



may be considered as a factor in the selection of such brokers or dealers. A
higher cost broker-dealer will not be selected, however, solely on the basis of
sales volume but will be selected in accordance with the criteria set forth
above.

      To the extent research services are used by the subadvisers in rendering
investment advice to NASL, such services would tend to reduce the subadvisers'
expenses. However, the subadvisers do not believe that an exact dollar value can
be assigned to these services. Research services received by the subadvisers
from brokers or dealers executing transactions for NASL will be available also
for the benefit of other portfolios managed by the subadvisers.

      The subadvisers manage a number of accounts other than the NASL
Portfolios. Although investment recommendations or determinations for the NASL
portfolios will be made by the subadvisers independently from the investment
recommendations and determinations made by them for any other account,
investments deemed appropriate for the NASL Portfolios by the subadvisers may
also be deemed appropriate by them for other accounts, so that the same security
may be purchased or sold at or about the same time for both the NASL Portfolios
and other accounts. In such circumstances, the subadvisers may determine that
orders for the purchase or sale of the same security for the NASL Portfolios and
one or more other accounts should be combined, in which event the transactions
will be priced and allocated in a manner deemed by the subadvisers to be
equitable and in the best interests of the NASL Portfolios and such other
accounts. While in some instances combined orders could adversely affect the
price or volume of a security, NASL believes that its participation in such
transactions on balance will produce better overall results for NASL.

      For the years ended December 31, 1995, 1994 and 1993, NASL paid brokerage
commissions in connection with portfolio transactions of $6,609,957, $5,510,656
and $2,877,317, respectively.


                        PURCHASE AND REDEMPTION OF SHARES

      NASL will redeem all full and fractional portfolio shares for cash at the
net asset value per share of each NASL Portfolio. Payment for shares redeemed
will generally be made within seven days after receipt of a proper notice of
redemption. However, NASL may suspend the right of redemption or postpone the
date of payment beyond seven days during any period when (a) trading on the New
York Stock Exchange is restricted, as determined by the Securities and Exchange
Commission, or such Exchange is closed for other than weekends and holidays; (b)
an emergency exists, as determined by the Commission, as a result of which
disposal by NASL of securities owned by it is not reasonably practicable or it
is not reasonably practicable for NASL fairly to determine the value of its net
assets; or (c) the Commission by order so permits for the protection of security
holders of NASL.


                        DETERMINATION OF NET ASSET VALUE

      The following supplements the discussion of the valuation of portfolio
assets set forth in the Prospectus/Proxy Statement under the caption "Additional
Information About NASL--D. Purchase and Redemption of Shares."

      Securities held by the NASL Portfolios except for debt instruments with
remaining maturities of 60 days or less and all debt instruments held by the
NASL Money Market Trust will be valued as follows: securities which are traded
on stock exchanges (including securities traded in both the over-the-counter
market and on an exchange) are valued at the last sales price as of the close of
the regularly scheduled trading of the New York Stock Exchange on the day the
securities are being valued, 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 New York Stock Exchange. Securities and assets for which market
quotations are not readily available are valued at fair value as determined in
good faith by or under the direction of the NASL Board.

      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 the regularly scheduled trading of the New
York Stock Exchange. The values of such securities used in computing the net
asset value of a NASL Portfolio's shares 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 the
New York Stock Exchange and would therefore not be reflected in the computation
of a NASL Portfolio'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 NASL Board.

      Debt instruments with a remaining maturity of 60 days or less held by each
of the NASL Portfolios other than the NASL Money Market Trust, and all
instruments held by the NASL Money Market Trust, will be valued on an amortized
cost basis.

                                      -22-


<PAGE>   151



Under this method of valuation, the instrument is initially valued at cost (or
in the case of instruments initially valued at market value, at the market value
on the day before its remaining maturity is such that it qualifies for amortized
cost valuation); thereafter, NASL assumes a constant proportionate amortization
in value until maturity of any discount or premium, regardless of the impact of
fluctuating interest rates on the market value of the instrument. While this
method provides certainty in valuation, it may result in periods during which
value, as determined by amortized cost, is higher or lower than the price that
would be received upon sale of the instrument.

      The NASL Money Market Trust uses the amortized cost valuation method in
reliance upon Rule 2a-7 under the Investment Company Act of 1940. As required by
the Rule, the NASL Money Market Trust will maintain a dollar weighted average
maturity of 90 days or less. In addition, the NASL Money Market Trust is
permitted to purchase only securities that the NASL Board determines to present
minimal credit risks and which are at the time of purchase "eligible
securities," as defined by the Rule. Generally, eligible securities must be
rated by a nationally recognized statistical rating organization in one of the
two highest rating categories for short-term debt obligations or be of
comparable quality. The NASL Money Market Trust will invest only in obligations
that have remaining maturities of thirteen months or less.

   
      The NASL Board has established procedures designed to stabilize, to the
extent reasonably possible, the NASL Money Market Trust's price per share as
computed for the purpose of sales and redemptions at $10.00. Such procedures
include a direction to NASL Financial to establish procedures which will allow
for the monitoring of the propriety of the continued use of amortized cost
valuation to maintain a constant net asset value of $10.00 per share. Such
procedures include a directive to NASL Financial that requires that on
determining net asset value per share based upon available market quotations,
the NASL Money Market Trust shall value weekly (a) all portfolio instruments for
which market quotations are readily available at market, and (b) all portfolio
instruments for which market quotations are not readily available or are not
obtainable from a pricing service, at their fair value as determined in good
faith by the NASL Board, although the actual calculations may be made by persons
acting pursuant to the direction of the NASL Board. If the fair value of a
security needs to be determined, the subadviser will provide determinations, in
accordance with procedures and methods established by the NASL Board, of the
fair value of securities held by the NASL Money Market Trust for which market
quotations are not readily available for purposes of enabling the NASL Money
Market Trust's Custodian to calculate net asset value. NASL Financial, with the
subadviser's assistance, periodically (but no less frequently than annually)
shall prepare a written report to the NASL Board verifying the accuracy of the
pricing system or estimate. A non-negotiable security which is not treated as an
illiquid security because it may be redeemed with the issuer, subject to a
penalty for early redemption, shall be assigned a value that takes into account
the reduced amount that would be received if it were currently liquidated. In
the event that the deviation from the amortized cost exceeds .50 of 1% or more
or a difference of $.05 per share in net asset value, NASL Financial shall
promptly call a special meeting of the NASL Board to determine what, if any,
action should be initiated. Where the NASL Board believes the extent of any
deviation from the NASL Money Market Trust's amortized cost price per share may
result in material dilution or other unfair results to investors or existing
shareholders, they shall take such action as they deem appropriate to eliminate
or reduce to the extent reasonably practical such dilution or unfair results.
The actions that may be taken by the NASL Board include, but are not limited to:
(a) redeeming shares in kind; (b) selling portfolio instruments prior to
maturity to realize capital gains or losses or to shorten the average portfolio
maturity of the NASL Money Market Trust; (c) withholding or reducing
dividends;(d) utilizing a net asset value per share based on available market
quotations; (e) investing all cash in instruments with a maturity on the next
business day. The NASL Money Market Trust may also reduce the number of shares
outstanding by redeeming proportionately from shareholders, without the payment
of any monetary compensation, such number of full and fractional shares as is
necessary to maintain the net asset value at $10.00 per share. Any such
redemption will be treated as a negative dividend for purposes of the Net
Investment Factor under the contracts issued by North American Security Life
Insurance Company, First North American Life Assurance Company and The
Manufacturers Life Insurance Company of America.
    


                                PERFORMANCE DATA

      Each of the NASL Portfolios may quote total return figures in its
advertising and sales materials. Such figures will always include the average
annual total return for recent one year and, when applicable, five and ten year
periods and where less than five or ten years, the period since the NASL
Portfolio (including, in the case of the NASL Money Market Trust, its
predecessor prior to the reorganization of the Fund on December 31, 1988) became
available for investment. In the case of the NASL Pacific Rim Emerging Markets,
NASL Real Estate Securities, NASL Common Stock, NASL Capital Growth Bond and
NASL Equity Index Trusts, such quotations will be for periods that include the
performance of the corresponding Manulife Portfolios. Where the period since
inception is less than one year, the total return quoted will be the aggregate
return for the period. The average annual total return is the average annual
compounded rate of return that equates the initial amount invested to the

                                      -23-


<PAGE>   152



market value of such investment on the last day of the period for which such
return is calculated. For purposes of the calculation it is assumed that an
initial payment of $1,000 is made on the first day of the period for which the
return is calculated and that all dividends and distributions are reinvested at
the net asset value on the reinvestment dates during the period. All recurring
fees such as advisory fees charged to NASL and all NASL expenses are reflected
in the calculations. There are no non-recurring fees such as sales loads,
surrender charges or account fees charged by NASL. If the period since inception
is less than one year, the figures will be based on an aggregate total return
rather than an average annual total return.

                              ORGANIZATION OF NASL


SHARES OF NASL

      The Declaration of Trust authorizes the NASL Board to issue an unlimited
number of full and fractional shares of beneficial interest having a par value
of $.01 per share, to divide such shares into an unlimited number of series of
shares and to designate the relative rights and preferences thereof, all without
shareholder approval. NASL currently has thirty series of shares: the NASL Small
Cap Trust, the NASL International Small Cap Trust, the NASL Small/Mid Cap Trust,
the NASL Aggressive Growth Trust, the NASL Pacific Rim Emerging Markets Trust,
the NASL International Stock Trust, the NASL Global Equity Trust, the NASL
Worldwide Growth Trust, the NASL Science & Technology Trust, the NASL Growth
Trust, the NASL Equity Trust, the NASL Common Stock Trust, the NASL Real Estate
Securities Trust, the NASL Blue Chip Growth Trust, the NASL Equity-Income Trust,
the NASL Value Trust, the NASL International Growth and Income Trust, the NASL
Growth and Income Trust, the NASL Equity Index Trust, the NASL Balanced Trust,
the NASL Aggressive Asset Allocation Trust, the NASL Moderate Asset Allocation
Trust, the NASL Conservative Asset Allocation Trust, the NASL High Yield Trust,
the NASL Strategic Bond Trust, the NASL Global Government Bond Trust, the NASL
Capital Growth Bond Trust, the NASL Investment Quality Bond Trust, the NASL U.S.
Government Securities Trust and the NASL Money Market Trust. The shares of each
NASL Portfolio, when issued and paid for, will be fully paid and non-assessable
and will have no preemptive or

                                      -24-


<PAGE>   153



conversion rights. Holders of shares of any NASL Portfolio are entitled to
redeem their shares as set forth under "Additional Information About NASL--D.
Purchase and Redemption of Shares." NASL reserves the right to later issue
additional series of shares or separate classes of existing series of shares
without the consent of outstanding shareholders.

      Each issued and outstanding share is entitled to participate equally in
dividends and distributions declared by the respective NASL Portfolio and upon
liquidation in the net assets of such NASL Portfolio remaining after
satisfaction of outstanding liabilities. For these purposes and for purposes of
determining the sale and redemption prices of shares, any assets which are not
clearly allocable to a particular NASL Portfolio will be allocated in the manner
determined by the NASL Board. Accrued liabilities which are not clearly
allocable to one or more NASL Portfolios will also be allocated among the NASL
Portfolios in the manner determined by the NASL Board. Shareholders of each
portfolio of NASL are entitled to one vote for each full share held (and
fractional votes for fractional shares held) irrespective of the relative net
asset values of the shares of the NASL Portfolio. All shares entitled to vote
are voted by series, except that when voting for the election of the NASL Board
and when otherwise permitted by the Investment Company Act of 1940, shares are
voted in the aggregate and not by series. Only shares of a particular NASL
Portfolio are entitled to vote on matters determined by the NASL Board to affect
only the interests of that NASL Portfolio. Pursuant to the Investment Company
Act of 1940 and the rules and regulations thereunder, certain matters approved
by a vote of a majority of all the shareholders of NASL may not be binding on a
NASL Portfolio whose shareholders have not approved such matter. There will
normally be no meetings of shareholders for the purpose of electing Trustees
unless and until less than a majority of the Trustees holding office has been
elected by shareholders, at which time the Trustees then in office will call a
shareholders' meeting for the election of Trustees. Holders of not less than
two-thirds of the outstanding shares of NASL may remove a Trustee by a vote cast
in person or by proxy at a meeting called for such purpose. Shares of NASL do
not have cumulative voting rights, which means that the holders of more than 50%
of NASL's shares voting for the election of Trustees can elect all of the
Trustees if they so choose. In such event, the holders of the remaining shares
would not be able to elect any Trustees.

      Under Massachusetts law, shareholders of NASL could, under certain
circumstances, be held personally liable for the obligations of NASL. The
Declaration of Trust contains an express disclaimer of shareholder liability for
acts or obligations of NASL and requires that notice of such disclaimer be given
in each agreement, obligation, or instrument entered into or executed by the
NASL Board or any officer of NASL. The Declaration of Trust provides for
indemnification out of the property of a NASL Portfolio for all losses and
expenses of any shareholder held personally liable for the obligations of such
NASL Portfolio. The Declaration of Trust also provides that NASL shall, upon
request, assume the defense of any claim made against any shareholder for any
act or obligation of NASL and satisfy any judgment thereon, but only out of the
property of a particular NASL Portfolio. Thus, the risk of a shareholder
incurring financial loss on account of shareholder liability is limited to
circumstances in which a particular NASL Portfolio would be unable to meet its
obligations.

      NASL currently has three shareholders: The Manufacturers Life Insurance
Company of America ("Manulife America"), Security Life and First North American
Life Assurance Company ("FNAL"). Each shareholder holds NASL shares attributable
to variable and variable life contracts in their separate accounts. Each
shareholder will solicit voting instructions from such variable and variable
life contract owners and vote all shares held in proportion to the instructions
received.
    

      Reflecting the conditions of section 817(h) and other provisions of the
Internal Revenue Code and regulations thereunder, the By-laws of NASL provide
that shares of NASL may be purchased only by the following eligible
shareholders: (a) separate accounts of Security Life or of other insurance
companies; (b) Security Life; (c) NASL Financial; (d) any corporation related in
a manner specified in section 267(b) of the Internal Revenue Code to Security
Life or to NASL Financial, including North American Life; and (e) any Trustee of
a qualified pension of retirement plan. As a matter of operating policy, shares
of NASL may be purchased only by the eligible shareholders of categories (a),
(b) and (d).

NASL SERIES TRUST/MANULIFE SERIES FUND, INC.
NOTES TO PRO FORMA FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

1. BASIS OF COMBINATION. The Pro Forma Combining Schedule of Portfolio
Investments, the Statement of Assets and Liabilities and the Statement of
Operations reflect the accounts of the NASL Series Trust Money Market Trust
("NASL Money Market"), one of seventeen investment portfolios offered by the
NASL Series Trust (the "Trust") and the Manulife Series Fund Money Market Fund
("MSF Money Market"), one of nine investment portfolios offered by the Manulife
Series Fund, Inc. (the "Fund") for the six months ended June 30, 1996. These
statements have been derived from the books and records of each portfolio
utilized in calculating daily net asset value at June 30, 1996.

The Pro Forma statements reflect the proposed transfer of the assets and
liabilities of MSF Money Market in exchange for shares of NASL Money Market.
Under generally accepted accounting principles ("GAAP"), the NASL Money Market
will be the surviving entity for accounting purposes. The Pro Forma financial
statements have been adjusted to reflect the anticipated fee arrangements for
the surviving entity and do not reflect the expenses of either portfolio in
carrying out its obligations under the Agreement and Plan of Reorganization.

The Pro Forma Combining Schedule of Portfolio Investments, Statement of Assets
and Liabilities and Statement of Operations should be read in conjunction with
the historical financial statements of NASL Money Market and MSF Money Market
incorporated by reference in the Statement of Additional Information.

NASL Financial Services, Inc. ("NASL Financial"), a wholly-owned subsidiary of
North American Security Life ("Security Life"), serves as investment adviser to
NASL Money Market for which it receives a fee for services, computed daily and
paid monthly, at the annual rate 0.50% of the average daily net assets of NASL
Money Market. Security Life is controlled by The Manufacturers Life Insurance
Company ("Manulife Financial"), a mutual life insurance company based in
Toronto, Canada.

Manufacturers Adviser Corporation ("MAC"), a wholly-owned subsidiary of The
Manufacturers Life Insurance Company of America, which in turn is a wholly-owned
subsidiary of The Manulife Reinsurance Corporation (USA)("MRC"), serves as
investment adviser to MSF Money Market for which it receives a fee for services,
computed daily and paid monthly, at an annual rate of 0.50% of the average daily
net assets of MSF Money Market. MRC is a life insurance holding company
organized in 1983 under Michigan law and is a wholly-owned subsidiary of
Manulife Financial.

Pro Forma Adjustments:
- ---------------------

(A) Adjustment to reflect reinvestment of undistributed net investment income.
(B) Adjustment to reflect amount allocated to capital shares ($0.01 par value)
    for shares issued to MSF Money Market Fund in reorganization.
(C) Adjustment to reflect change in MSF Money Market Fund expense structure due
    to reorganization calculated based upon average net assets.

2. SIGNIFICANT ACCOUNTING POLICIES. The policies described below are followed by
the Trust in the preparation of the financial statements for its portfolios in
conformity with generally accepted accounting principles ("GAAP").

SECURITY VALUATION. Securities held by NASL Money Market with remaining
maturities of 60 days or less are valued on an amortized cost basis or at
original cost plus accrued interest, both of which approximate current market
value.

SECURITIES LENDING. The Trust may lend securities in amounts up to 33 1/3% of
its total non-cash assets to brokers, dealers and other financial institutions,
provided such loans are callable at any time and are at all times fully secured
by cash, cash equivalents or securities issued or guaranteed by the U.S.
government or its agencies or instrumentalities, marked to market to the value
of the loaned securities on a daily basis. The Trust may bear the risk of delay
in recovery of, or even of rights in, the securities loaned should the borrower
of the securities fail financially. Consequently, loans of portfolio securities
will only be made to firms deemed by the subadvisers to be creditworthy. The
Trust receives compensation for lending its securities either in the form of
fees or by retaining a portion of interest on the investment of any cash
received as collateral. Income generated from the investment of cash collateral
is included as interest income in the Statement of Operations. All collateral
received will be in an amount equal to at least 100% of the market value of the
loaned securities and must be maintained at that level during the period of the
loan. During the loan period, the fund continues to retain rights of ownership,
including dividends and interest of the loaned securities.

FEDERAL INCOME TAXES. The Trust's policy is to qualify as a "regulated
investment company" under Subchapter M of the Internal Revenue Code, as amended,
and to distribute all of its taxable income to its shareholders. Accordingly, no
federal income tax provision is required. Each portfolio of the Trust is treated
as a separate taxpayer for federal income tax purposes.

DISTRIBUTION OF INCOME AND GAINS. All of the net investment income of NASL Money
Market is declared as a dividend to shareholders of record as of the close of
business each day and is reinvested daily. During any particular year, net
realized gains from investment transactions of each portfolio, in excess of
available capital loss carryforwards of each portfolio would be taxable to such
portfolio if not distributed. Therefore, each portfolio of the Trust intends to
distribute all of its investment company taxable income and any net realized
capital gains in order to avoid federal income tax. Each portfolio of the Trust
is exempt from federal excise tax. Net investment income is reported in the
accompanying statements under GAAP. The Trust's distributions are based on
income amounts determined in accordance with federal income tax regulations.
Overdistributions of net investment income as determined in accordance with GAAP
have been presented in the financial statements as distributions in excess of
net investment income. Net investment income and net realized gains differ for
financial statement and tax purposes due to distributions in accordance with
income tax regulations which may differ from GAAP: marking-to-market of certain
financial instruments, the deferral of certain losses for tax purposes and the
treatment of currency gains or losses. As a result, the character of
distributions made during the year from net investment income may differ from
its ultimate characterization for tax purposes.

SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

EXPENSE ALLOCATION. Expenses not directly attributable to a particular portfolio
are allocated based on the relative share of net assets of each portfolio for
the time during which the expense was incurred.

REPURCHASE AGREEMENTS. Each portfolio of the Trust may enter into repurchase
agreements. When a portfolio enters into a repurchase agreement through its
custodian, it receives delivery of the underlying securities, the amount of
which at the time of purchase and each subsequent business day is required to be
maintained at such a level that the market value is 102% of the repurchase
amount. Each portfolio will take constructive receipt of all securities
underlying the repurchase agreements it has entered into until such agreements
expire. If the seller defaults, a portfolio would suffer a loss to the extent
that proceeds from the sale of underlying securities were less than the
repurchase amount.

CAPITAL ACCOUNTS. The Trust reports the accumulated undistributed net investment
income (loss) and accumulated undistributed net realized gain (loss) accounts on
a basis approximating amounts available for future tax distributions (or to
offset future taxable realized gains when a capital loss carryforward is
available). Accordingly, each portfolio of the Trust may periodically make
reclassifications among certain capital accounts without impacting the net asset
value.

OTHER. Investment security transactions are accounted for on a trade date plus
one basis. Interest income is accrued as earned. Dividend income and
distributions to shareholders are recorded on the ex-dividend date. All original
issue discounts are accreted for financial and tax reporting purposes. The Trust
uses the First In, First Out method for determining realized gain or loss on
investments for both financial and federal income tax reporting purposes. The
preparation of financial statements in conformity with GAAP requires management
to make estimates and assumptions that affect the reported amount of assets and
liabilities. Actual results may differ from these estimates.

3. CAPITAL SHARES. The Pro Forma net asset value per share assumes the issuance
of shares of NASL Money Market which would have been issued at June 30, 1996 had
the proposed reorganization taken place on such date. The amount of additional
shares assumed to be issued was calculated based on the per share net asset
value of NASL Money Market ($10.00).

NOTES TO PRO FORMA FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------


1. SIGNIFICANT ACCOUNTING POLICIES. The policies described below are followed by
the NASL Series Trust (the "Trust") in the preparation of the Pro Forma
financial statements for the following nine portfolios: The Common Stock Trust
("Common Stock"), the Pacific Rim Emerging Markets Trust ("Pacific Rim Emerging
Markets"), the Real Estate Securities Trust ("Real Estate Securities"), the
Capital Growth Bond Trust ("Capital Growth Bond"), the Equity Index Trust
("Equity Index"), the International Stock Trust ("International Stock"), the
Emerging Growth Trust ("Emerging Growth") and the Balanced Trust ("Balanced") in
conformity with generally accepted accounting principles ("GAAP"). These
statements have been derived from the books and records of each portfolio
utilized in calculating daily net asset value at June 30, 1996.

SECURITY VALUATION. Short term instruments with remaining maturities of 60 days
or less held by the other portfolios of the Trust are valued on an amortized
cost basis or at original cost plus accrued interest, both of which approximate
current market value. All other securities held by the Trust are valued at the
last sale price as of the close of business on a principal securities exchange
(domestic or foreign) 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 making markets in the securities at the close of
trading on the Exchange.

Trust securities for which there are no such quotations, principally debt
securities, are valued on the basis of the valuation provided by a pricing
service which utilizes both dealer-supplied and electronic data processing
techniques. Other assets and securities for which no such quotations are readily
available are valued at their fair value as determined in good faith under
consistently applied procedures established by and under the general supervision
of the Board of Trustees.

FOREIGN CURRENCY TRANSLATIONS. The accounting records of the Trust are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars on the following basis:

         (i)   market value of securities, other assets and other liabilities at
               the current rate of exchange of such currencies against U.S.
               dollars;

         (ii)  purchases and sales of securities, income and expenses at the
               rate of exchange quoted on the respective dates of such
               transactions.

Gains and losses that arise from changes in foreign exchange rates have been
segregated from gains and losses that arise from changes in the market prices of
investments. These gains and losses are included with gains and losses on
foreign currency and forward foreign currency contracts in the Statements of
Operations.

FORWARD FOREIGN CURRENCY CONTRACTS. All portfolios with the exception of Equity
Index may purchase and sell forward foreign currency contracts in order to hedge
a specific transaction or portfolio position.

The net U.S. dollar value of foreign currency underlying all contractual
commitments held at the end of the period and the resulting net unrealized
appreciation (depreciation) and related net receivable or payable amount are
determined using forward foreign currency exchange rates supplied by a quotation
service. The Trust could be exposed to risks if the counterparties to the
contracts are unable to meet the terms of their contracts or if the value of the
foreign currency changes unfavorably.

Net realized gains (losses) on foreign currency and forward foreign currency
contracts shown in the Statements of Operations, include net gains or losses
realized by a portfolio on contracts which have matured or which the portfolio
has terminated by entering into an offsetting commitment with the same broker.

FUTURES. All portfolios may purchase and sell financial futures contracts and
options on those contracts. The portfolios invest in contracts based on
financial instruments such as U.S. Treasury bonds or notes or on securities
indices such as the S&P 500 Index, in order to hedge against a decline in the
value of securities owned by the portfolios.

When a portfolio sells a futures contract based on a financial instrument, the
portfolio becomes obligated to deliver that kind of instrument at an agreed upon
date for a specified price. The portfolio realizes a gain or loss depending on
whether the price of an offsetting purchase is less or more than the price of
the initial sale or on whether the price of an offsetting sale is more or less
than the price of the initial purchase . The Trust could be exposed to risks if
it could not close out futures positions because of an illiquid secondary market
or the inability of counterparties to meet the terms of their contracts. Upon
entering into futures contracts, the Trust is required to deposit with a broker
an amount, initial margin, which represents 5% of the purchase price indicated
in the futures contract.

Payments to and from the broker, known as variation margin, are required to be
made on a daily basis as the price of the futures contract fluctuates, making
the long or short positions in the contract more or less valuable. If the
position is closed out by taking an opposite position prior to the settlement
date of the futures contract, a final determination of variation margin is made,
cash is required to be paid to or released by the broker, and the portfolio
realizes a gain or loss.

SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

FORWARD COMMITMENTS. The portfolios of the Trust may purchase debt securities on
a when issued or forward delivery basis, which means that the obligations will
be delivered to the portfolios of the Trust at a future date, which may be a
month or more after the date of commitment. The price of the underlying
securities and the date when the securities will be delivered and paid for are
fixed at the time the transaction is negotiated. The value of the securities
underlying a forward commitment to purchase securities, and the subsequent
fluctuations in their value, is taken into account when determining the Trust's
net asset value starting on the day the Trust agrees to purchase the securities.

SECURITIES LENDING. The Trust may lend securities in amounts up to 33 1/3% of
its total non-cash assets to brokers, dealers and other financial institutions,
provided such loans are callable at any time and are at all times fully secured
by cash, cash equivalents or securities issued or guaranteed by the U.S.
government or its agencies or instrumentalities, marked to market to the value
of the loaned securities on a daily basis. The Trust may bear the risk of delay
in recovery of, or even of rights in, the securities loaned should the borrower
of the securities fail financially. Consequently, loans of portfolio securities
will only be made to firms deemed by the subadvisers to be creditworthy. The
Trust receives compensation for lending its securities either in the form of
fees or by retaining a portion of interest on the investment of any cash
received as collateral. Income generated from the investment of cash collateral
is included as interest income in the Statement of Operations. All collateral
received will be in an amount equal to at least 100% of the market value of the
loaned securities and must be maintained at that level during the period of the
loan. During the loan period, the fund continues to retain rights of ownership,
including dividends and interest of the loaned securities.


MORTGAGE DOLLAR ROLLS. All portfolios may enter into mortgage dollar rolls in
which they sell mortgage securities for delivery in the current month and
simultaneously contract to repurchase similar, but not identical, securities at
the same price on an agreed upon date. The Trusts receive compensation as
consideration for entering into the commitment to repurchase. The compensation
is recorded as deferred income and amortized to income over the roll period. As
the holder, the counterparty receives all principal and interest payments,
including prepayments, made with respect to the similar security. Mortgage
dollar rolls may be renewed with a new sale and repurchase price with a cash
settlement made at renewal without physical delivery of the securities subject
to the contract.


FEDERAL INCOME TAXES. The Trust's policy is to qualify as a "regulated
investment company" under Subchapter M of the Internal Revenue Code, as amended,
and to distribute all of its taxable income to its shareholders. Accordingly, no
federal income tax provision is required. Each portfolio of the Trust is treated
as a separate taxpayer for federal income tax purposes.


DISTRIBUTION OF INCOME AND GAINS. During any particular year, net realized gains
from investment transactions of each portfolio, in excess of available capital
loss carryforwards of each portfolio would be taxable to such portfolio if not
distributed. Therefore, each portfolio of the Trust intends to distribute all of
its investment company taxable income and any net realized capital gains in
order to avoid federal income tax. Each portfolio of the Trust is exempt from
federal excise tax. Net investment income is reported in the accompanying
statements under GAAP. The Trust's distributions are based on income amounts
determined in accordance with federal income tax regulations. Overdistributions
of net investment income as determined in accordance with GAAP have been
presented in the financial statements as distributions in excess of net
investment income. Net investment income and net realized gains differ for
financial statement and tax purposes due to distributions in accordance with
income tax regulations which may differ from GAAP: marking-to-market of certain
financial instruments, the deferral of certain losses for tax purposes and the
treatment of currency gains or losses. As a result, the character of
distributions made during the year from net investment income may differ from
its ultimate characterization for tax purposes.

EXPENSE ALLOCATION. Expenses not directly attributable to a particular portfolio
are allocated based on the relative share of net assets of each portfolio for
the time during which the expense was incurred.

REPURCHASE AGREEMENTS. Each portfolio of the Trust may enter into repurchase
agreements. When a portfolio enters into a repurchase agreement through its
custodian, it receives delivery of the underlying securities, the amount of
which at the time of purchase and each subsequent business day is required to be
maintained at such a level that the market value is 102% of the repurchase
amount. Each portfolio will take constructive receipt of all securities
underlying the repurchase agreements it has entered into until such agreements
expire. If the seller defaults, a portfolio would suffer a loss to the extent
that proceeds from the sale of underlying securities were less than the
repurchase amount.

CAPITAL ACCOUNTS. The Trust reports the accumulated undistributed net investment
income (loss) and accumulated undistributed net realized gain (loss) accounts on
a basis approximating amounts available for future tax distributions (or to
offset future taxable realized gains when a capital loss carryforward is
available). Accordingly, each portfolio of the Trust may periodically make
reclassifications among certain capital accounts without impacting the net asset
value.

OTHER. Investment security transactions are accounted for on a trade date plus
one basis. Interest income is accrued as earned. Dividend income and
distributions to shareholders are recorded on the ex-dividend date. All original
issue discounts are accreted for financial and tax reporting purposes. The Trust
uses the First In, First Out method for determining realized gain or loss on
investments for both financial and federal income tax reporting purposes. The
preparation of financial statements in conformity with GAAP requires management
to make estimates and assumptions that affect the reported amount of assets and
liabilities. Actual results may differ from these estimates.


2.  PRO FORMA ADJUSTMENTS.

(A)  Adjustment to reflect amount allocated to capital shares ($0.01 par value)
     for shares issued in reorganization.
(B)  Adjustment to reflect change in investment advisory fee and other expenses
     due to reorganization, calculated based upon average net assets and
     allocated based upon budgeted spending amounts.
(C)  Adjustment to reflect the advisor's voluntary fee waiver limiting total
     fund operating expenses to .50% of average net assets.

NASL SERIES TRUST/MANULIFE SERIES FUND, INC.
NOTES TO PRO FORMA FINANCIAL STATEMENTS - CONTINUED
- --------------------------------------------------------------------------------

1. BASIS OF COMBINATION. The Pro Forma Combining Schedule of Portfolio
Investments, the Statement of Assets and Liabilities and the Statement of
Operations reflect the accounts of the NASL Series Trust Money Market Trust
("NASL Money Market"), one of seventeen investment portfolios offered by the
NASL Series Trust (the "Trust") and the Manulife Series Fund Money Market Fund
("MSF Money Market"), one of eight investment portfolios offered by the Manulife
Series Fund, Inc. (the "Fund") for the year ended December 31, 1995. These
statements have been derived from the books and records of each portfolio
utilized in calculating daily net asset value at December 31, 1995.

The Pro Forma statements reflect the proposed transfer of the assets and
liabilities of MSF Money Market in exchange for shares of NASL Money Market.
Under generally accepted accounting principles ("GAAP"), the NASL Money Market
will be the surviving entity for accounting purposes. The Pro Forma financial
statements have been adjusted to reflect the anticipated fee arrangements for
the surviving entity and do not reflect the expenses of either portfolio in
carrying out its obligations under the Agreement and Plan of Reorganization.

The Pro Forma Combining Schedule of Portfolio Investments, Statement of Assets
and Liabilities and Statement of Operations should be read in conjunction with
the historical financial statements of NASL Money Market and MSF Money Market
incorporated by reference in the Statement of Additional Information.

NASL Financial Services, Inc. ("NASL Financial"), a wholly-owned subsidiary of
North American Security Life ("Security Life"), serves as investment adviser to
NASL Money Market for which it receives a fee for services, computed daily and
paid monthly, at the annual rate 0.50% of the average daily net assets of NASL
Money Market. Security Life is controlled by The Manufacturers Life Insurance
Company ("Manulife Financial"), a mutual life insurance company based in
Toronto, Canada.

Manufacturers Adviser Corporation ("MAC"), a wholly-owned subsidiary of The
Manufacturers Life Insurance Company of America, which in turn is a wholly-owned
subsidiary of The Manulife Reinsurance Corporation (USA)("MRC"), serves as
investment adviser to MSF Money Market for which it receives a fee for services,
computed daily and paid monthly, at an annual rate of 0.50% of the average daily
net assets of MSF Money Market. MRC is a life insurance holding company
organized in 1983 under Michigan law and is a wholly-owned subsidiary of
Manulife Financial.

Pro Forma Adjustments:
- ---------------------

(A) Adjustment to reflect reinvestment of undistributed net investment income.
(B) Adjustment to reflect amount allocated to capital shares ($0.01 par value)
    for shares issued to MSF Money Market Fund in reorganization.
(C) Adjustment to reflect change in MSF Money Market expense structure due to
    reorganization calculated based upon average net assets.

2. SIGNIFICANT ACCOUNTING POLICIES. The policies described below are followed by
the Trust in the preparation of the financial statements for its portfolios in
conformity with generally accepted accounting principles ("GAAP").

SECURITY VALUATION. Securities held by NASL Money Market with remaining
maturities of 60 days or less are valued on an amortized cost basis or at
original cost plus accrued interest, both of which approximate current market
value.

SECURITIES LENDING. The Trust may lend securities in amounts up to 33 1/3% of
its total non-cash assets to brokers, dealers and other financial institutions,
provided such loans are callable at any time and are at all times fully secured
by cash, cash equivalents or securities issued or guaranteed by the U.S.
government or its agencies or instrumentalities, marked to market to the value
of the loaned securities on a daily basis. The Trust may bear the risk of delay
in recovery of, or even of rights in, the securities loaned should the borrower
of the securities fail financially. Consequently, loans of portfolio securities
will only be made to firms deemed by the subadvisers to be creditworthy. The
Trust receives compensation for lending its securities either in the form of
fees or by retaining a portion of interest on the investment of any cash
received as collateral. Income generated from the investment of cash collateral
is included as interest income in the Statement of Operations. All collateral
received will be in an amount equal to at least 100% of the market value of the
loaned securities and must be maintained at that level during the period of the
loan. During the loan period, the fund continues to retain rights of ownership,
including dividends and interest of the loaned securities.

FEDERAL INCOME TAXES. The Trust's policy is to qualify as a "regulated
investment company" under Subchapter M of the Internal Revenue Code, as amended,
and to distribute all of its taxable income to its shareholders. Accordingly, no
federal income tax provision is required. Each portfolio of the Trust is treated
as a separate taxpayer for federal income tax purposes.

DISTRIBUTION OF INCOME AND GAINS. All of the net investment income of NASL Money
Market is declared as a dividend to shareholders of record as of the close of
business each day and is reinvested daily. During any particular year, net
realized gains from investment transactions of each portfolio, in excess of
available capital loss carryforwards of each portfolio would be taxable to such
portfolio if not distributed. Therefore, each portfolio of the Trust intends to
distribute all of its investment company taxable income and any net realized
capital gains in order to avoid federal income tax. Each portfolio of the Trust
is exempt from federal excise tax. Net investment income is reported in the
accompanying statements under GAAP. The Trust's distributions are based on
income amounts determined in accordance with federal income tax regulations.
Overdistributions of net investment income as determined in accordance with GAAP
have been presented in the financial statements as distributions in excess of
net investment income. Net investment income and net realized gains differ for
financial statement and tax purposes due to distributions in accordance with
income tax regulations which may differ from GAAP: marking-to-market of certain
financial instruments, the deferral of certain losses for tax purposes and the
treatment of currency gains or losses. As a result, the character of
distributions made during the year from net investment income may differ from
its ultimate characterization for tax purposes.

SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

EXPENSE ALLOCATION. Expenses not directly attributable to a particular portfolio
are allocated based on the relative share of net assets of each portfolio for
the time during which the expense was incurred.

REPURCHASE AGREEMENTS. Each portfolio of the Trust may enter into repurchase
agreements. When a portfolio enters into a repurchase agreement through its
custodian, it receives delivery of the underlying securities, the amount of
which at the time of purchase and each subsequent business day is required to be
maintained at such a level that the market value is 102% of the repurchase
amount. Each portfolio will take constructive receipt of all securities
underlying the repurchase agreements it has entered into until such agreements
expire. If the seller defaults, a portfolio would suffer a loss to the extent
that proceeds from the sale of underlying securities were less than the
repurchase amount.

CAPITAL ACCOUNTS. The Trust reports the accumulated undistributed net investment
income (loss) and accumulated undistributed net realized gain (loss) accounts on
a basis approximating amounts available for future tax distributions (or to
offset future taxable realized gains when a capital loss carryforward is
available). Accordingly, each portfolio of the Trust may periodically make
reclassifications among certain capital accounts without impacting the net asset
value.

OTHER. Investment security transactions are accounted for on a trade date plus
one basis. Interest income is accrued as earned. Dividend income and
distributions to shareholders are recorded on the ex-dividend date. All original
issue discounts are accreted for financial and tax reporting purposes. The Trust
uses the First In, First Out method for determining realized gain or loss on
investments for both financial and federal income tax reporting purposes. The
preparation of financial statements in conformity with GAAP requires management
to make estimates and assumptions that affect the reported amount of assets and
liabilities. Actual results may differ from these estimates.

3. CAPITAL SHARES. The Pro Forma net asset value per share assumes the issuance
of shares of NASL Money Market which would have been issued at December 31, 1995
had the proposed reorganization taken place on such date. The amount of
additional shares assumed to be issued was calculated based on the per share net
asset value of NASL Money Market ($10.00).

NASL SERIES TRUST/MANULIFE SERIES FUND, INC.
NOTES TO PRO FORMA FINANCIAL STATEMENTS (UNAUDITED)
- -------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES. The policies described below are followed by
the NASL Series Trust (the "Trust") in the preparation of the Pro Forma
financial statements for the following eight portfolios: The Common Stock Trust
("Common Stock"), the Pacific Rim Emerging Markets Trust ("Pacific Rim Emerging
Markets"), the Real Estate Securities Trust ("Real Estate Securities"), the
Capital Growth Bond Trust ("Capital Growth Bond"), the International Stock Trust
("International Stock"), the Emerging Growth Trust ("Emerging Growth") and the
Balanced Trust ("Balanced") in conformity with generally accepted accounting
principles ("GAAP"). These statements have been derived from the books and
records of each portfolio utilized in calculating daily net asset value at
December 31, 1995.

SECURITY VALUATION. Short term instruments with remaining maturities of 60 days
or less held by the other portfolios of the Trust are valued on an amortized
cost basis or at original cost plus accrued interest, both of which approximate
current market value. All other securities held by the Trust are valued at the
last sale price as of the close of business on a principal securities exchange
(domestic or foreign) 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 making markets in the securities at the close of
trading on the Exchange.

Trust securities for which there are no such quotations, principally debt
securities, are valued on the basis of the valuation provided by a pricing
service which utilizes both dealer-supplied and electronic data processing
techniques. Other assets and securities for which no such quotations are readily
available are valued at their fair value as determined in good faith under
consistently applied procedures established by and under the general supervision
of the Board of Trustees.

FOREIGN CURRENCY TRANSLATIONS. The accounting records of the Trust are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars on the following basis:

         (i)      market value of securities, other assets and other liabilities
                  at the current rate of exchange of such currencies against
                  U.S. dollars;

         (ii)     purchases and sales of securities, income and expenses at the
                  rate of exchange quoted on the respective dates of such
                  transactions.

Gains and losses that arise from changes in foreign exchange rates have been
segregated from gains and losses that arise from changes in the market prices of
investments. These gains and losses are included with gains and losses on
foreign currency and forward foreign currency contracts in the Statements of
Operations.

FORWARD FOREIGN CURRENCY CONTRACTS. All portfolios with the exception of Equity
Index may purchase and sell forward foreign currency contracts in order to hedge
a specific transaction or portfolio position.

The net U.S. dollar value of foreign currency underlying all contractual
commitments held at the end of the period and the resulting net unrealized
appreciation (depreciation) and related net receivable or payable amount are
determined using forward foreign currency exchange rates supplied by a quotation
service. The Trust could be exposed to risks if the counterparties to the
contracts are unable to meet the terms of their contracts or if the value of the
foreign currency changes unfavorably.

Net realized gains (losses) on foreign currency and forward foreign currency
contracts shown in the Statements of Operations, include net gains or losses
realized by a portfolio on contracts which have matured or which the portfolio
has terminated by entering into an offsetting commitment with the same broker.

FUTURES. All portfolios may purchase and sell financial futures contracts and
options on those contracts. The portfolios invest in contracts based on
financial instruments such as U.S. Treasury bonds or notes or on securities
indices such as the S&P 500 Index, in order to hedge against a decline in the
value of securities owned by the portfolios.

When a portfolio sells a futures contract based on a financial instrument, the
portfolio becomes obligated to deliver that kind of instrument at an agreed upon
date for a specified price. The portfolio realizes a gain or loss depending on
whether the price of an offsetting purchase is less or more than the price of
the initial sale or on whether the price of an offsetting sale is more or less
than the price of the initial purchase. The Trust could be exposed to risks if
it could not close out futures positions because of an illiquid secondary market
or the inability of counterparties to meet the terms of their contracts. Upon
entering into futures contracts, the Trust is required to deposit with a broker
an amount, initial margin, which represents 5% of the purchase price indicated
in the futures contract.

Payments to and from the broker, known as variation margin, are required to be
made on a daily basis as the price of the futures contract fluctuates, making
the long or short positions in the contract more or less valuable. If the
position is closed out by taking an opposite position prior to the settlement
date of the futures contract, a final determination of variation margin is made,
cash is required to be paid to or released by the broker, and the portfolio
realizes a gain or loss.

FORWARD COMMITMENTS. The portfolios of the Trust may purchase debt securities on
a when issued or forward delivery basis, which means that the obligations will
be delivered to the portfolios of the Trust at a future date, which may be a
month or more after the date of commitment. The price of the underlying
securities and the date when the securities will be delivered and paid for are
fixed at the time the transaction is negotiated. The value of the securities
underlying a forward commitment to purchase securities, and the subsequent
fluctuations in their value, is taken into account when determining the Trust's
net asset value starting on the day the Trust agrees to purchase the securities.

SECURITIES LENDING. The Trust may lend securities in amounts up to 33 1/3% of
its total non-cash assets to brokers, dealers and other financial institutions,
provided such loans are callable at any time and are at all times fully secured
by cash, cash equivalents or securities issued or guaranteed by the U.S.
government or its agencies or instrumentalities, marked to market to the value
of the loaned securities on a daily basis. The Trust may bear the risk of delay
in recovery of, or even of rights in, the securities loaned should the borrower
of the securities fail financially. Consequently, loans of portfolio securities
will only be made to firms deemed by the subadvisers to be creditworthy. The
Trust receives compensation for lending its securities either in the form of
fees or by retaining a portion of interest on the investment of any cash
received as collateral. Income generated from the investment of cash collateral
is included as interest income in the Statement of Operations. All collateral
received will be in an amount equal to at least 100% of the market value of the
loaned securities and must be maintained at that level during the period of the
loan. During the loan period, the fund continues to retain rights of ownership,
including dividends and interest of the loaned securities.

MORTGAGE DOLLAR ROLLS. All portfolios may enter into mortgage dollar rolls in
which they sell mortgage securities for delivery in the current month and
simultaneously contract to repurchase similar, but not identical, securities at
the same price on an agreed upon date. The Trusts receive compensation as
consideration for entering into the commitment to repurchase. The compensation
is recorded as deferred income and amortized to income over the roll period. As
the holder, the counterparty receives all principal and interest payments,
including prepayments, made with respect to the similar security. Mortgage
dollar rolls may be renewed with a new sale and repurchase price with a cash
settlement made at renewal without physical delivery of the securities subject
to the contract.

FEDERAL INCOME TAXES. The Trust's policy is to qualify as a "regulated
investment company" under Subchapter M of the Internal Revenue Code, as amended,
and to distribute all of its taxable income to its shareholders. Accordingly, no
federal income tax provision is required. Each portfolio of the Trust is treated
as a separate taxpayer for federal income tax purposes.

DISTRIBUTION OF INCOME AND GAINS. During any particular year, net realized gains
from investment transactions of each portfolio, in excess of available capital
loss carryforwards of each portfolio would be taxable to such portfolio if not
distributed. Therefore, each portfolio of the Trust intends to distribute all of
its investment company taxable income and any net realized capital gains in
order to avoid federal income tax. Each portfolio of the Trust is exempt from
federal excise tax. Net investment income is reported in the accompanying
statements under GAAP. The Trust's distributions are based on income amounts
determined in accordance with federal income tax regulations. Overdistributions
of net investment income as determined in accordance with GAAP have been
presented in the financial statements as distributions in excess of net
investment income. Net investment income and net realized gains differ for
financial statement and tax purposes due to distributions in accordance with
income tax regulations which may differ from GAAP: marking-to-market of certain
financial instruments, the deferral of certain losses for tax purposes and the
treatment of currency gains or losses. As a result, the character of
distributions made during the year from net investment income may differ from
its ultimate characterization for tax purposes.

EXPENSE ALLOCATION. Expenses not directly attributable to a particular portfolio
are allocated based on the relative share of net assets of each portfolio for
the time during which the expense was incurred.

REPURCHASE AGREEMENTS. Each portfolio of the Trust may enter into repurchase
agreements. When a portfolio enters into a repurchase agreement through its
custodian, it receives delivery of the underlying securities, the amount of
which at the time of purchase and each subsequent business day is required to be
maintained at such a level that the market value is 102% of the repurchase
amount. Each portfolio will take constructive receipt of all securities
underlying the repurchase agreements it has entered into until such agreements
expire. If the seller defaults, a portfolio would suffer a loss to the extent
that proceeds from the sale of underlying securities were less than the
repurchase amount.

CAPITAL ACCOUNTS. The Trust reports the accumulated undistributed net investment
income (loss) and accumulated undistributed net realized gain (loss) accounts on
a basis approximating amounts available for future tax distributions (or to
offset future taxable realized gains when a capital loss carryforward is
available). Accordingly, each portfolio of the Trust may periodically make
reclassifications among certain capital accounts without impacting the net asset
value.

OTHER. Investment security transactions are accounted for on a trade date plus
one basis. Interest income is accrued as earned. Dividend income and
distributions to shareholders are recorded on the ex-dividend date. All original
issue discounts are accreted for financial and tax reporting purposes. The Trust
uses the First In, First Out method for determining realized gain or loss on
investments for both financial and federal income tax reporting purposes. The
preparation of financial statements in conformity with GAAP requires management
to make estimates and assumptions that affect the reported amount of assets and
liabilities. Actual results may differ from these estimates.

2. PRO FORMA ADJUSTMENTS.

(A) Adjustment to reflect amount allocated to capital shares ($0.01 par value)
    for shares issued in reorganization.
(B) Adjustment to reflect change in investment advisory fee and other expenses
    due to reorganization, calculated based upon average net assets and 
    allocated based upon budgeted spending amounts.
(C) Adjustment to reflect the advisor's voluntary fee waiver limiting total
    fund operating expenses to .50% of average net assets.

      (a)   The undersigned Registrant agrees that prior to any public
            reoffering of the securities registered through the use of a
            prospectus which is a part of this Registration Statement by any
            person or party who is deemed to be an underwriter within the

            prospectus will contain the information called for by the applicable
            registration form for reofferings by persons who may be deemed
            underwriters, in addition to the information called for by the other

      (b)   The undersigned Registrant agrees that every prospectus that is

            the amendment is effective, and that, in determining any liability
            under the 1933 Act, each post-effective amendment shall be deemed to
            be a new registration statement for the securities offered therein,
            and the offering of the securities at that time shall be deemed to
            be the initial bona fide offering of them.
