                        SELECT CAPITAL APPRECIATION FUND
                              SMALL CAP VALUE FUND
                                  GROWTH FUND
                               SELECT GROWTH FUND
                         SELECT GROWTH AND INCOME FUND

specific insurance  product  you  have  chosen will  indicate  which  Funds  are
available,  and should be read in conjunction with this Prospectus. Inclusion in
this Prospectus of a Fund which is not available under your policy is not to  be
considered a solicitation.

MAINTAIN A STABLE NET ASSET VALUE OF $1.00 PER SHARE.
 
    THIS PROSPECTUS SHOULD BE READ AND RETAINED FOR FUTURE REFERENCE.
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND

                           HOW ARE THE FUNDS MANAGED?
 
   
    The  overall responsibility for the supervision  of the affairs of the Trust
vests in the  Board of  Trustees of  the Trust who  meet on  a quarterly  basis.
Allmerica Investment Management Company, Inc. (the "Manager") is responsible for
the  management  of  the Trust's  day-to-day  business affairs  and  has general
responsibility for the management of the investments of the Funds. The  Manager,
at  its  expense,  has  contracted  with  certain  Sub-Advisers  to  manage  the
investments of the Funds, subject to the requirements of the Investment  Company
Act of 1940 (the "1940 Act").
    
 
   
    The  Manager  is  a  wholly-owned  subsidiary  of  First  Allmerica,  a life
insurance company, which was  organized in Massachusetts  in 1844. The  Manager,
organized  August 19, 1985,  also serves as  manager of the  Allmerica Funds, an
open-end investment company. The Manager and First Allmerica are located at  440
Lincoln Street, Worcester, Massachusetts 01653.
    
 
    The  Manager has entered  into Sub-Adviser Agreements  for the management of
the investments of each of the  Funds. The Sub-Advisers, who have been  selected
on  the  basis of  various factors  including management  experience, investment
techniques and staffing, are each authorized to engage in portfolio transactions
on  behalf  of  the  applicable  Funds  subject  to  such  general  or  specific
instructions  as may be given by the Trustees and/or the Manager. The terms of a
Sub-Adviser Agreement cannot  be materially  changed without the  approval of  a
majority  interest of  the shareholders of  the affected  Fund. The Sub-Advisers
have been selected  by the  Manager and  Trustees in  consultation with  Rogers,
Casey  & Associates  ("Rogers, Casey"), a  leading pension  consulting firm. The
cost of such consultation is borne by the Manager.
 
    Rogers, Casey  provides consulting  services to  pension plans  representing
over  $150 billion in total assets and, in its consulting capacity, monitors the
investment performance  of over  1,000 investment  advisers. From  time to  time
specific  clients of Rogers, Casey  and the Sub-Advisers will  be named in sales
materials.  At  times,  Rogers,  Casey  assists  in  the  development  of  asset
allocation  strategies which may be used  by shareholders in the diversification
of their portfolio across different asset classes.
 
   
    Ongoing performance  of the  Sub-Advisers  is reviewed  and evaluated  by  a
committee  which  includes  members who  may  include senior  officers  of First
Allmerica,  its  affiliates  or  the  Manager  and  an  independent  consultant.
Combined,  the committee has over 150 years of investment experience. Historical
performance data for all Funds is set forth in the "Financial Highlights"  table
starting  on page 3.  The Manager is  solely responsible for  the payment of all
fees to the Sub-Advisers. The Sub-Advisers for each of the Funds are as follows:

                WHAT ARE THE INVESTMENT OBJECTIVES AND POLICIES?
 
    Each  Fund has a separate investment objective and policies designed to meet
different investment  and  financial needs,  as  described below.  There  is  no
assurance that a Fund will achieve its investment objective.
 
   
    The  Select International Equity Fund, Select Aggressive Growth Fund, Select
Capital Appreciation Fund, Select Growth Fund and Select Growth and Income  Fund
may each invest up to 15% of its assets in securities which are illiquid because
they are subject to restriction on resale or for which market quotations are not
readily  available. Each  of the Funds  except the  Select International Equity,
Select Capital Appreciation, Small Cap  Value, Government Bond and Money  Market
Fund may invest up to 25% of its assets in foreign securities (not including its
investments   in  American   Depositary  Receipts  ("ADRs")),   and  the  Select
International Equity  Fund and  the Select  Capital Appreciation  Fund may  each
invest  any percentage of its assets in foreign securities. The Investment Grade
Income Fund may not invest in  foreign securities other than obligations  issued
by  the Government  of Canada and  political subdivisions  thereof. See "Certain
Investment Strategies and Policies".  The Select Growth  Fund and Select  Growth
and  Income  Fund  each may  invest  up to  35%  of its  assets  in fixed-income
securities, including  not more  than 15%  in lower-rated  securities,  commonly
known as "junk bonds." The Select Capital Appreciation Fund may invest up to 35%
of  its assets in such lower-rated  securities. Fixed-income securities rated in
the fourth  highest grade  by  Moody's Investors  Service, Inc.  ("Moody's")  or
Standard  & Poor's  Ratings Service, a  division of  McGraw-Hill Companies, Inc.
("S&P") (Baa and BBB, respectively) are  investment grade but are considered  to
have  some speculative  characteristics. Lower-rated securities  or "junk bonds"
(rated Ba/BB or  lower) involve  the risks discussed  under "Certain  Investment
Strategies and Policies."
    
 
    A  Fund's investment objective is fundamental and may not be changed without
shareholder approval. Unless otherwise  indicated, a Fund's investment  policies
are not fundamental and may be changed without shareholder approval.
 
SELECT INTERNATIONAL EQUITY FUND
 
    INVESTMENT  OBJECTIVE:  The  Select International Equity  Fund seeks maximum
long-term total return (capital appreciation and income) primarily by  investing
in common stocks of established non-U.S. companies.
 
   
    SUB-ADVISER:    Bank of  Ireland  Asset Management  (U.S.)  Limited ("BIAM")
serves as  Sub-Adviser for  the Select  International Equity  Fund. BIAM  is  an
indirect  wholly-owned subsidiary of Bank of Ireland. Its main offices are at 26
Fitzwilliam Place, Dublin  2, Ireland.  Its U.S.  offices are  at Two  Greenwich
Plaza,  Greenwich,  CT 06830.  Bank  of Ireland  provides  investment management
services through a network of sister companies, including BIAM which  represents
North  American  clients.  As of  December  31,  1995, Bank  of  Ireland managed
approximately $15  billion  in  global securities  for  Irish,  United  Kingdom,
European and U.S. clients.
    
 
    INVESTMENT  POLICIES:   To achieve  its objective,  the Select International
Equity Fund  will invest  primarily  in common  stocks of  established  non-U.S.
companies.  Under normal  market conditions,  at least  65% of  the Fund's total
assets will be  invested in the  securities of companies  domiciled in at  least
five  foreign  countries, not  including the  United States.  The Fund  may also
acquire fixed-income debt securities. It will do so, at the discretion of  BIAM,
primarily for defensive purposes.
 
   
    The   Fund's  investments  may  include  ADRs  which  may  be  sponsored  or
unsponsored by  the  underlying  issuer.  The Fund  may  also  utilize  European
Depositary  Receipts  ("EDRs"),  which  are similar  to  ADRs,  in  bearer form,
designed for  use  in  the  European securities  market  and  Global  Depositary
Receipts  ("GDRs"). Investments in foreign securities carry additional risks not
present in domestic securities. See "Certain Investment Strategies and  Policies
- --  Foreign  Securities." The  Fund  may, for  hedging  purposes, engage  in the
options and futures  strategies described under  "Certain Investment  Strategies
and  Policies."  Certain  state  insurance  regulations  may  impose  additional
restrictions on the Fund's holdings of foreign securities.
    
 
                                       10
<PAGE>
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the Fund was 24%. The portfolio turnover rate for the Fund may vary greatly from
year to year.
    
 
SELECT AGGRESSIVE GROWTH FUND
 
    INVESTMENT OBJECTIVE:  The Select Aggressive Growth Fund seeks above-average
capital appreciation by investing primarily in common stocks of companies  which
are believed to have significant potential for capital appreciation.
 
   
    SUB-ADVISER:    Nicholas-Applegate  Capital  Management  ("NACM")  serves as
Sub-Adviser to the Select Aggressive Growth Fund. NACM is an investment  manager
supervising  accounts with  approximately $29 billion  as of  December 31, 1995.
NACM's clients  are primarily  major corporate  employee benefit  funds,  public
employee retirement plans, foundations and endowment funds, investment companies
and  individuals. Founded in 1984,  NACM is located at  600 West Broadway, Suite
2900, San Diego, California 92101.
    
 
    INVESTMENT POLICIES:  Under normal circumstances, at least 65% of the assets
of the Select  Aggressive Growth  Fund will  be invested  in equity  securities,
consisting   of  common  stocks,  securities   convertible  into  common  stocks
(including bonds, notes and  preferred stocks) and  warrants. The Fund's  assets
may  also be invested  in other debt  securities and preferred  stocks when such
securities are believed appropriate in light of the Fund's investment  objective
and market conditions.
 
    The  selection of securities  is made solely  on the basis  of potential for
capital appreciation.  Dividend  and interest  income,  if any,  from  portfolio
securities  is incidental to the  Fund's investment objective. While investments
may be made in  well-known and established companies,  a significant portion  of
the  Fund's investments is expected to be  in securities of newer and relatively
unseasoned companies or companies which represent new or changing industries.
 
    At any given point  a substantial portion of  the Fund's equity  investments
may  be in securities  which are not  listed for trading  on national securities
exchanges and,  although publicly  traded, may  be less  liquid than  securities
issued  by larger,  more seasoned companies  which trade  on national securities
exchanges. Up to  15% of  the Fund's  assets may  be invested  in restricted  or
illiquid securities.
 
    Securities  of newer companies may be closely held with only a small portion
of their outstanding securities owned by the general public. Newer companies may
have relatively small revenue, lack depth  of management and have a small  share
of  the market for their products or services; thus, they may be more vulnerable
to changes  in  economic  conditions,  market  fluctuations  and  other  factors
affecting  the profitability  or marketability  of companies.  Due to  these and
other factors, the  price movement of  the securities  held by the  Fund can  be
expected to be more volatile than is the case for the market as a whole, and the
net   asset  value  of  a  share   of  the  Fund  may  fluctuate  significantly.
Consequently, the Fund should not be  considered suitable for investors who  are
unable  or unwilling to assume the risk of loss inherent in an aggressive growth
portfolio, nor  should  investment in  the  Fund  be considered  a  balanced  or
complete investment program.
 
   
    When  NACM determines that  market conditions warrant  a temporary defensive
position, the Fund  may invest  without limitation  in high-grade,  fixed-income
securities,  U.S.  Government  securities,  or  hold  assets  in  cash  or  cash
equivalents. The  Fund may,  for hedging  purposes, engage  in the  options  and
futures strategies described under "Certain Investment Strategies and Policies".
    
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the   Fund  was  104%.  The  portfolio   turnover  rate  was  104%  because  the
Sub-Adviser's investment approach typically  results in above-average  portfolio
turnover  as securities are  sold when the Sub-Adviser  believes the reasons for
their initial purchase are no longer valid or when it believes that the sale  of
a  security owned by the  Fund and the purchase  of another security can enhance
return. A security may be sold to avoid a prospective decline in market value or
purchased in anticipation of a market rise. Although it
    
 
                                       11
<PAGE>
   
is not possible to predict future portfolio turnover rates accurately, and  such
rates  may vary  greatly from  year to  year, NACM  anticipates that  the annual
portfolio turnover generally  will not  exceed 100%. A  high portfolio  turnover
rate will likely result in greater brokerage costs to the Fund.
    
 
SELECT CAPITAL APPRECIATION FUND
 
    INVESTMENT  OBJECTIVE:  The Select Capital Appreciation Fund seeks long-term
growth of  capital in  a manner  consistent with  the preservation  of  capital.
Realization  of income  is not  a significant  investment consideration  and any
income realized on  the Fund's  investments will  be incidental  to its  primary
objective.
 
   
    SUB-ADVISER:  Janus Capital Corporation ("JCC") serves as Sub-Adviser to the
Select  Capital Appreciation Fund.  JCC has served as  investment adviser to the
Janus Fund since 1969 and currently serves  as investment adviser to all of  the
Janus  retail funds, as well as adviser or sub-adviser to other mutual funds and
individual, corporate, charitable and retirement accounts. Kansas City  Southern
Industries, Inc. ("KCSI") owns approximately 83% of the outstanding voting stock
of JCC. KCSI is a publicly traded holding company whose primary subsidiaries are
engaged  in transportation and financial services.  As of December 31, 1995, JCC
had approximately $30 billion in total  assets under management. JCC is  located
at 100 Fillmore Street, Denver, Colorado 80206-4923.
    
 
   
    INVESTMENT POLICIES:  The Fund invests in common stocks when the Sub-Adviser
believes  that the  relevant market  environment favors  profitable investing in
those securities. The Fund pursues its objective by normally investing at  least
50%  of  its  equity  assets in  securities  issued  by  medium-sized companies.
Medium-sized companies are  those whose market  capitalizations fall within  the
range  of companies in the S&P MidCap  400 Index (the "MidCap Index"). Companies
whose capitalization falls outside this range after the Fund's initial  purchase
continue to be considered medium-sized companies for the purpose of this policy.
As   of  December   29,  1995,   the  MidCap   Index  included   companies  with
capitalizations between approximately $118 million to $7.5 billion. The range of
the MidCap Index is expected to change on a regular basis. Subject to the  above
policy,  the Fund  may also  invest in  smaller or  large issuers.  Common stock
investments are  selected  in  industries and  companies  that  the  Sub-Adviser
believes  are experiencing favorable demand for their products and services, and
which operate in a favorable competitive environment and regulatory climate. The
Sub-Adviser's analysis and  selection process  focuses on  stocks with  earnings
growth  potential that may not be recognized  by the market. Such securities are
selected solely for their capital growth  potential; investment income is not  a
consideration. Medium-sized companies may suffer more significant losses as well
as realize more substantial growth than larger issues; thus, investments in such
companies tend to be more volatile and somewhat speculative.
    
 
   
    The  selection  criteria for  domestic issuers  apply  equally to  stocks of
foreign issuers.  In addition,  factors such  as expected  levels of  inflation,
government  policies influencing  business conditions, the  outlook for currency
relationships, and  prospects  for  relative economic  growth  among  countries,
regions  or  geographic areas  may  warrant greater  consideration  in selecting
foreign stocks. The Fund  may invest without  limitation in foreign  securities.
The  Fund  may  invest directly  in  foreign securities  denominated  in foreign
currency and  not  publicly traded  in  the United  States.  The Fund  also  may
purchase foreign securities through ADRs, EDRs, GDRs and other types of receipts
or  shares  evidencing  ownership  of  the  underlying  foreign  securities.  In
addition, the Fund may invest  indirectly in foreign securities through  foreign
investment  funds or  trusts (including  passive foreign  investment companies).
Certain state insurance  regulations may impose  additional restrictions on  the
Fund's  holdings of foreign securities.  Investments in foreign securities carry
additional risks not  present in  domestic securities.  See "Certain  Investment
Strategies and Policies -- Foreign Securities."
    
 
    Although  the Fund normally  invests primarily in  common stocks, the Fund's
cash position may increase when the  Sub-Adviser is unable to locate  investment
opportunities  with desirable  risk/ reward  characteristics. The  Fund also may
invest in preferred stocks, warrants, government securities, corporate bonds and
debentures, high-grade commercial  papers, certificates of  deposit, other  debt
 
                                       12
<PAGE>
securities  or repurchase  agreement or  reverse repurchase  agreements when the
Sub-Adviser perceives an opportunity for capital growth from such securities  or
so that the Fund may receive a return on its idle cash. The Fund also may invest
in  debt securities rated below investment  grade, which involve risks discussed
under "Certain Investment  Strategies and  Policies." When the  Fund invests  in
such  securities, investment  income will  increase and  may constitute  a large
portion of  the return  realized by  the Fund  and the  Fund probably  will  not
participate  in market advances  or declines to  the extent that  it would if it
remained fully invested in common stocks.
 
    The Fund may  invest in "special  situations" from time  to time. A  special
situation  arises when, in the  opinion of the Sub-Adviser,  the securities of a
particular issuer will be recognized and  appreciate in value due to a  specific
development  with  respect  to  that  issuer.  Developments  creating  a special
situation might include, among others, a new product or process, a technological
breakthrough, a management  change or  other extraordinary  corporate event,  or
differences  in  market supply  of and  demand for  the security.  Investment in
special situations may carry an  additional risk of loss  in the event that  the
anticipated  development  does  not  occur  or  does  not  attract  the expected
attention.
 
    The Fund may, for hedging purposes, engage in options and futures strategies
and  may  utilize  forward  contracts,  interest  rate  swaps  and  swap-related
products. See "Certain Investment Strategies and Policies."
 
   
    For  the  fiscal  period  April 28,  1995  (commencement  of  operations) to
December 31,  1995,  the portfolio  turnover  rate for  the  Fund was  95%.  The
portfolio turnover rate for the Fund may vary from year to year.
    
 
SMALL CAP VALUE FUND
 
    INVESTMENT  OBJECTIVE:  The  Small Cap Value Fund  seeks long-term growth of
capital by investing primarily  in a diversified portfolio  of common stocks  of
smaller,  faster-growing companies whose securities at  the time of purchase are
considered by the Sub-Adviser to be realistically valued in the smaller  company
sector of the market.
 
   
    SUB-ADVISER:  David L. Babson & Co. Inc. ("Babson") serves as Sub-Adviser to
the  Small Cap  Value Fund. Founded  in 1940,  Babson had over  $12.6 billion in
assets under management as of December 31, 1995, and provides investment  advice
to individuals, state and local government agencies, pensions and profit sharing
plans,  trusts, estates, banks  and other organizations, and  also serves as the
investment adviser  to  the  Babson  Funds  (a  family  of  mutual  funds).  The
Sub-Adviser  is  an indirect  subsidiary of  MassMutual  Holding Company  and is
located at One Memorial Drive, Cambridge, Massachusetts 02142.
    
 
    INVESTMENT POLICIES:  A stock will  be considered to be attractively  valued
and, therefore, eligible for investment in the Fund, if it is trading at a price
which  the Sub-Adviser believes is reasonable relative to its own past valuation
history as well as  compared to a  large universe of stocks  as selected by  the
investment adviser, based on one or more of the following comparisons:
 
        1.  price relative to earnings,
 
        2.  price relative to sales,
 
        3.  price relative to assets as measured by book value.
 
    The  Small Cap Value  Fund generally intends  to invest at  least 65% of its
total assets in stocks of smaller  companies with market capitalization of  $250
million to $1 billion at the time of purchase and which are listed on a national
or  regional  exchange  or  over-the-counter with  prices  quoted  daily  in the
financial press. The Fund at times  may invest temporarily in preferred  stocks,
bonds  or other defensive  issues. Normally, however, the  Fund will maintain at
least 80%  of the  portfolio in  common  stocks. There  are no  restrictions  or
guidelines  regarding  the investment  of  Fund assets  in  shares listed  on an
exchange or traded over-the-counter.
 
                                       13
<PAGE>
    The Small Cap Value Fund seeks superior, but often neglected, companies with
significant  (and  usually  dominant)  market  share,  sustainable   competitive
advantage  in their  primary business, solid  finances, and  stable or improving
margins. A strong valuation discipline is applied to potential investments  with
target   companies   possessing   above-average   growth   potential   that   is
underestimated by the market,  providing attractive valuations. These  companies
typically  operate profitable  businesses, are outside  Wall Street's spotlight,
and are not widely held by institutional investors. The portfolio is diversified
among different  industry sectors,  but is  not an  index approach.  Stocks  are
bought  as investments  and generally  held for  the long  term, rather  than as
active trading vehicles.
 
   
    Small  cap  companies   may  present  greater   opportunities  for   capital
appreciation,  but  also may  involve greater  risk.  Small cap  companies, when
compared to larger cap companies, may  be more dependent upon a single  product,
may  have  limited financial  resources,  fewer securities  outstanding,  and be
somewhat less liquid than securities of larger companies.
    
 
    The Fund does not  intend to invest  in any security which,  at the time  of
purchase, is not readily marketable.
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the Fund was 17%. The portfolio turnover rate for the Fund may vary from year to
year.
    
 
GROWTH FUND
 
    INVESTMENT  OBJECTIVE:  The Growth Fund seeks to achieve long-term growth of
capital  through  investments   primarily  in  common   stocks  and   securities
convertible  into  common  stocks  that are  believed  to  represent significant
underlying value in relation  to current market  prices. Realization of  current
income, if any, is incidental to this objective.
 
   
    SUB-ADVISER:  Miller Anderson & Sherrerd, LLP ("MAS") is Sub-Adviser for the
Growth  Fund.  MAS, which  is wholly  owned by  Morgan Stanley  Asset Management
Holdings, Inc., is located at One Tower Bridge, West Conshohocken,  Pennsylvania
19428.  MAS provides investment  counseling services to  employee benefit plans,
endowment funds, foundations,  and other institutional  investors, and had  over
$35  billion in  assets under  management as  of December  31, 1995.  MAS is the
adviser of the  MAS Fund,  a registered investment  company offering  investment
alternatives  to institutional clients, with a  minimum initial investment of $1
million. MAS also manages certain assets for First Allmerica and its affiliates.
    
 
   
    INVESTMENT POLICIES:  The Growth Fund  is not limited to investments in  any
particular  type of company and may invest  in any company which, in the opinion
of management, is likely  to further its investment  objective. The Growth  Fund
will  pursue  its  investment  objective  by  maintaining  a  flexible  position
regarding the type of companies as well as the types of securities, in which  it
will  invest. Investments  may include,  but are  not limited  to, developing or
well-established companies, whether small or large. It is anticipated that there
will be a mix of assets in the Growth Fund. For example, portions of the  Growth
Fund may be invested in equity securities of good quality or in well-established
companies  considered  to  represent  good  value,  based  on  factors including
historical  investment   standards  (such   as  price/book   value  ratios   and
price/earnings  ratios) or in smaller emerging growth companies which are in the
development stage  and are  expected to  achieve above-average  earnings  growth
because  of  special  factors (such  as  changes  in the  economy,  the relative
attractiveness of  the  various  securities  markets,  or  changes  in  consumer
demand).
    
 
   
    The Growth Fund proposes to keep its assets fully invested, but may maintain
reasonable  amounts in cash or in high-grade, short-term debt securities to meet
current expenses  and  anticipated  redemptions, and  during  temporary  periods
pending  investment  in  accordance  with its  policies.  The  term "high-grade,
short-term debt  securities"  means Items  (a),  (b)  and (c)  of  Money  Market
Instruments under the Investment Grade Income Fund's Investment Policies.
    
 
    The  Growth Fund  normally will  invest substantially  all of  its assets in
equity-type securities, including common stocks, warrants (which are options  to
purchase common stock at specified prices
 
                                       14
<PAGE>
during a specified time period with the investment risk that the market value of
the  underlying common stock may  not be high enough  in relation to the warrant
exercise price to  justify purchase pursuant  to the terms  of the warrant)  and
those  preferred stocks and debt securities  convertible into or carrying rights
to purchase  common  stock  or  to participate  in  earnings,  and  real  estate
securities   to  the  extent  permitted   by  paragraph  four  under  Investment
Restrictions in the SAI. In periods  considered by management to warrant a  more
defensive  position,  the  Growth Fund  may  place  a larger  proportion  of its
portfolio  in  high-grade  preferred   stocks,  bonds,  or  other   fixed-income
securities,  including U.S.  Government securities,  whether or  not convertible
into stock or with rights attached, or  retain cash. The Fund may engage in  the
options  and futures  strategies described under  "Certain Investment Strategies
and Policies".
 
    The Growth  Fund may  invest in  both listed  and unlisted  securities.  The
Growth  Fund may also  invest in foreign,  as well as  domestic, securities. The
Growth Fund  will not  concentrate  its foreign  investments in  any  particular
foreign  country,  or  limit its  investments  to issuers  listed  on particular
exchanges or traded in particular  money market centers. Investments in  foreign
securities  carry  additional  risks  not present  in  domestic  securities. See
"Certain Investment  Strategies and  Policies".  The Sub-Adviser  will  consider
these  and other factors before investing and  will not cause the Growth Fund to
invest in foreign securities unless, in its opinion, such investments will  meet
the standards and objectives of the Growth Fund.
 
    The  investment  objective  and  policies in  the  first,  third  and fourth
paragraphs of this section  on the Growth  Fund are fundamental  and may not  be
changed without shareholder approval.
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the Fund was 64%. The portfolio turnover rate for the Fund may vary greatly from
year to year.
    
 
SELECT GROWTH FUND
 
    INVESTMENT  OBJECTIVE:   The Select Growth  Fund seeks  to achieve long-term
growth of capital by investing  in a diversified portfolio consisting  primarily
of common stocks selected on the basis of their long-term growth potential.
 
   
    SUB-ADVISER:   Provident Investment Counsel ("PIC") serves as Sub-Adviser to
the Select Growth Fund. PIC has been an investment manager for over 40 years. As
of December  31, 1995,  PIC had  assets under  management of  approximately  $18
billion. PIC provides investment advisory services to major corporate retirement
plans, public employee retirement plans, investment companies and foundation and
endowment  funds. PIC,  located at 300  North Lake  Avenue, Pasadena, California
91101, is a wholly-owned  subsidiary of United  Asset Management Corporation,  a
Boston-based  professional services holding company listed on the New York Stock
Exchange.
    
 
    INVESTMENT POLICIES:  The Select Growth  Fund seeks to attain its  objective
by  investing in securities of companies that appear to have favorable long-term
growth characteristics.  Potential for  long-term  growth is  the  determinative
factor  in  the selection  of all  portfolio securities.  Although the  Fund may
invest in dividend-paying  stocks, the generation  of current income  is not  an
objective  of the Fund. Any income that  is received is incidental to the Fund's
objective of long-term growth of capital.
 
    When choosing securities for the  portfolio, the Sub-Adviser for the  Select
Growth  Fund focuses on companies  that display strong financial characteristics
and earnings  growth potential,  whereas  the Sub-Adviser  for the  Growth  Fund
emphasizes a value-oriented approach which compares individual stocks and groups
of stocks to one another.
 
    At  least 65% of the  Fund's assets under normal  conditions will consist of
growth-oriented common stocks.  The Fund  may invest  in common  stock of  large
well-known  companies  as  well  as smaller  growth  companies,  which generally
include companies with a market capitalization of $500 million or less ("Smaller
Growth Companies"). The stocks of Smaller Growth Companies may involve a  higher
degree  of risk than  other types of  securities and the  price movement of such
securities can be expected to be more volatile than is the case of the market on
the whole. The Fund may hold stocks traded on
 
                                       15
<PAGE>
one or  more  of the  national  exchanges as  well  as in  the  over-the-counter
markets.  Because opportunities for capital growth may exist not only in new and
expanding areas of the economy but  also in mature and cyclical industries,  the
Fund's  portfolio investments are not limited  to any particular type of company
or industry. The Fund may also purchase convertible bonds and preferred  stocks,
warrants  and debt securities if the Fund's Sub-Adviser believes they would help
achieve the Fund's objective of long-term growth.
 
   
    The Fund  may invest  up  to 35%  of its  assets  in both  higher-rated  and
lower-rated fixed-income securities in seeking its objective of long-term growth
of  capital. The  dollar average  weighted maturity  of the  Fund's fixed-income
securities  will  vary  depending  on,   among  other  things,  current   market
conditions.  The  Fund  may  invest  up to  15%  of  its  assets  in lower-rated
securities, commonly known as "junk bonds", which involve risks discussed  under
"Certain  Investment Strategies  and Policies." For  more information concerning
the rating  categories of  corporate debt  securities see  the Appendix  to  the
Prospectus.
    
 
    When  the Sub-Adviser determines that  market conditions warrant a temporary
defensive position,  the  Fund  may invest  without  limitation  in  high-grade,
fixed-income  securities, U.S. Government securities, or  hold assets in cash or
cash equivalents. To the extent the Fund is so invested it is not achieving  its
objective  to the  same degree  as under  normal conditions.  The Fund  may, for
hedging purposes, engage in the  options and futures strategies described  under
"Certain Investment Strategies and Policies".
 
    The  Select Growth Fund's  objective of seeking  long-term growth of capital
means that its  assets generally will  be subject  to greater risk  than may  be
involved in investing in securities that are not selected for growth potential.
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the Fund was 51%. The portfolio turnover rate for the Fund may vary greatly from
year to year.
    
 
SELECT GROWTH AND INCOME FUND
 
    INVESTMENT OBJECTIVE:  The Select Growth and Income Fund seeks a combination
of  long-term  growth  of  capital  and current  income.  The  Fund  will invest
primarily in  dividend-paying  common  stocks and  securities  convertible  into
common stocks.
 
   
    SUB-ADVISER:  John A. Levin & Co., Inc. ("JAL") serves as Sub-Adviser to the
Growth  and Income  Fund. JAL  was founded  as a  Delaware corporation  in 1982.
Currently, shares of the corporation are held by six key employees. The firm had
approximately $5.6 billion in assets under  management as of December 31,  1995.
JAL's  clients include U.S. and foreign  individuals and their related trust and
charitable organizations;  pooled  funds  for individuals  and  university;  and
pension  and  profit sharing  funds.  JAL has  entered  into a  merger agreement
whereby  JAL  will  become  wholly  owned  by  Baker,  Fentress  &  Company,   a
non-diversified  closed-end management investment  company, registered under the
1940 Act. It is contemplated  the merger will be completed  prior to the end  of
1996.
    
 
    INVESTMENT  POLICIES:    To achieve  its  objective of  long-term  growth of
capital and  current income,  the  Select Growth  and  Income Fund  will  invest
primarily  in  dividend-paying  common stocks  and  securities  convertible into
common stocks. It may invest in a wide range of equity securities, consisting of
both dividend-paying and  non-dividend-paying common  stocks, preferred  stocks,
securities  convertible into common and preferred stocks and warrants. These may
include securities  of large  well-known  companies as  well as  Smaller  Growth
Companies.  The securities of Smaller Growth  Companies involve certain risks as
described above under  the "Select Growth  Fund." The Fund  may hold  securities
traded   on  one  or  more  of  the   national  exchanges  as  well  as  in  the
over-the-counter markets. The  Fund's portfolio investments  are not limited  to
any  particular type  of company or  industry. The Fund  may purchase individual
stocks not  presently paying  dividends which  offer opportunities  for  capital
growth  or  future income  provided that  the  Sub-Adviser believes  the overall
portfolio is  appropriately  positioned  to achieve  its  income  objective.  To
achieve  current income,  the Fund may  invest up to  35% of its  assets in both
higher-rated and lower-rated fixed-income securities,
 
                                       16
<PAGE>
   
including not more than 15% in  lower-rated securities, commonly known as  "junk
bonds".  In certain circumstances,  fixed-income securities may  be purchased by
the Fund for  long-term growth  potential. (However,  the Fund  expects to  have
substantially less than 35% of its assets invested in fixed-income securities in
most circumstances.) Lower-rated fixed-income securities involve risks discussed
under  "Certain  Investment  Strategies  and  Policies."  For  more  information
concerning the rating categories of  corporate debt securities see the  Appendix
to   the  Prospectus.  The  dollar  average  weighted  maturity  of  the  Fund's
fixed-income securities  will vary  depending on,  among other  things,  current
market  conditions. Purchases and sales of portfolio securities are made at such
times and in such amounts as deemed  advisable in light of market, economic  and
other conditions.
    
 
    When  the Sub-Adviser determines that  market conditions warrant a temporary
defensive position,  the  Fund  may invest  without  limitation  in  high-grade,
fixed-income  securities, U.S. Government securities, or  hold assets in cash or
cash equivalents. To the extent the Fund is so invested it is not achieving  its
objective  to the  same degree  as under  normal conditions.  The Fund  may, for
hedging purposes, engage in the  options and futures strategies described  under
"Certain  Investment  Strategies  and Policies".  There  can, of  course,  be no
assurance of  growth of  capital  and because  the  Fund invests  a  substantial
portion  of its assets in common stocks  and other securities which fluctuate in
value there is substantial risk of market decline. The Fund's Sub-Adviser  seeks
to minimize this risk through detailed analyses of financial markets and issuers
of  equity securities and through investment  in a diversified portfolio of such
securities.
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the Fund  was  112%. The  portfolio  turnover  rate exceeded  100%  because  the
Sub-Adviser  believes that  as securities  it has  purchased achieve appropriate
valuation, selling enhances return and reduces risk. The portfolio turnover rate
for the Fund may vary greatly from year to year. A high portfolio turnover  rate
will likely result in greater brokerage costs to the Fund.
    
 
EQUITY INDEX FUND
 
    INVESTMENT  OBJECTIVE:   The Equity Index  Fund seeks  to achieve investment
results that  correspond to  the  aggregate price  and  yield performance  of  a
representative selection of common stocks that are publicly traded in the United
States.
 
   
    SUB-ADVISER:  Allmerica Asset Management, Inc. ("AAM") serves as Sub-Adviser
to  the Equity Index  Fund as well  as Investment Grade  Income Fund, Government
Bond Fund  and  Money Market  Fund.  AAM,  a wholly-owned  subsidiary  of  First
Allmerica,  was  incorporated in  1993  and is  located  at 440  Lincoln Street,
Worcester, Massachusetts 01653. As of  December 31, 1995, AAM had  approximately
$10.85  billion in assets under management.  AAM serves as investment adviser to
First Allmerica's  General  Account and  to  a number  of  affiliated  insurance
companies  and other affiliated accounts and  as Adviser to Allmerica Securities
Trust, a diversified, closed-end management investment company.
    
 
   
    INVESTMENT POLICIES:    The Equity  Index  Fund  will seek  to  achieve  its
objective  by attempting to replicate the  aggregate price and yield performance
of the Standard &  Poor's Composite Index  of 500 Stocks  ("S&P 500"). The  Fund
uses  the S&P  500 as  the performance  standard because  it represents  over 70
percent of the total market  value of all publicly  traded common stocks in  the
U.S.,  is well-known to  investors, and, in  the opinion of  the Sub-Adviser, is
representative of the performance of common  stocks publicly traded in the  U.S.
Many, but not all, of the stocks in the S&P 500 are issued by companies that are
among  the  500 largest  as  measured by  the  aggregate market  value  of their
outstanding stock  (market  price  per  share multiplied  by  number  of  shares
outstanding).  Inclusion of a stock  in the S&P 500 does  not imply that S&P has
endorsed it as an investment. With respect to investing in common stocks,  there
can  be no assurance of capital appreciation  and there is a substantial risk of
market decline.
    
 
                                       17
<PAGE>
    The method used  to select investments  for the Fund  involves investing  in
common  stocks in approximately  the order of  their weightings in  the S&P 500,
beginning with  those  having the  highest  weightings. In  addition,  the  Fund
purchases  stocks with smaller weightings in order to represent other sectors of
the S&P 500 for diversification purposes.
 
    The Equity Index Fund will invest only in those stocks, and in such amounts,
as its Sub-Adviser  determines to be  necessary or appropriate  for the Fund  to
approximate  the performance  of the S&P  500. Under normal  circumstances it is
expected that the Fund will hold  between 300 and 475 different stocks  included
in  the S&P 500.  The Fund may  compensate for the  omission of a  stock that is
included in  the S&P  500,  or for  purchasing stocks  in  other than  the  same
proportions  that they are represented in the S&P 500, by purchasing stocks that
are believed to  have characteristics that  correspond to those  of the  omitted
stocks.  The Fund may invest in short-term debt securities to maintain liquidity
or pending investment in  stocks. The Fund  also may engage  in the options  and
futures strategies described under "Certain Investment Strategies and Policies."
 
   
    Because  of its policy of tracking the S&P 500, the Equity Index Fund is not
managed according to traditional methods of active investment management,  which
involve  the buying and selling of  securities based upon investment analysis of
economic, financial  and market  factors.  Consequently, the  projected  adverse
financial  performance of a company would not normally result in the sale of the
company's stock and projected superior financial performance by a company  would
not  normally lead to an  increase in the holdings of  the company. From time to
time the  Sub-Adviser may  make adjustments  in the  portfolio because  of  cash
flows,  mergers, changes in the composition of  the S&P 500 and similar reasons.
Portfolio turnover is expected  to be lower than  that of most investment  funds
investing  in common  stock. For  the fiscal year  ended December  31, 1995, the
portfolio turnover rate for the Fund was 8%.
    
 
    The Equity Index Fund's ability to duplicate the performance of the S&P  500
will be influenced by the size and timing of cash flows into or out of the Fund,
the  liquidity  of  the securities  included  in  the S&P  500,  transaction and
operating expenses, and other factors. In addition, the Fund will incur expenses
(including advisory  and administrative  fees)  that are  not reflected  in  the
performance  results of the S&P 500. These  factors, among others, may result in
"tracking error", which is a measure of  the degree to which the Fund's  results
differ  from the results of the S&P 500.  Due to such factors, the return of the
Fund may be lower than the return of the S&P 500.
 
   
    Tracking error is measured  by the difference between  total return for  the
S&P  500 with dividends reinvested and total  return for the Fund with dividends
reinvested after  deductions of  fees  and expenses.  For  the 12  months  ended
December  31, 1995  the S&P 500  gained 37.53% versus  a gain of  36.18% for the
Equity Index  Fund  producing a  tracking  error  of 1.35%.  Tracking  error  is
monitored  by the Sub-Adviser on a  regular basis. All tracking error deviations
are  reviewed  to  determine  the  effectiveness  of  investment  policies   and
techniques.  If the tracking error deviation  exceeds industry standards for the
Fund's asset size, the Sub-Adviser will bring the deviation to the attention  of
the Trustees.
    
 
    While  the Board of Trustees of the Trust has initially selected the S&P 500
as the index the Fund will attempt to replicate, the Trustees reserve the  right
to select another index at any time without seeking shareholder approval if they
believe  that the S&P 500 no longer represents a broad spectrum of common stocks
that are publicly traded in the United States or if there are legal, economic or
other factors limiting the use of  any particular index. If the Trustees  change
the  index which the Equity  Index Fund attempts to  replicate, the Equity Index
Fund may incur  significant transaction  costs in  switching from  one index  to
another.
 
    S&P  is not in any  way affiliated with the Equity  Index Fund or the Trust.

INVESTMENT GRADE INCOME FUND
 
    INVESTMENT OBJECTIVE:   The Investment  Grade Income  Fund seeks  as high  a
level of total return, which includes capital appreciation as well as income, as
is consistent with prudent investment management.
 
    SUB-ADVISER:  AAM serves as Sub-Adviser to the Investment Grade Income Fund.
See "Equity Index Fund" for more information about AAM.
 
    INVESTMENT POLICIES:  The Fund will invest its assets in the following money
market instruments and debt securities.
 
    MONEY MARKET INSTRUMENTS:
 
        (a)  Obligations issued or  guaranteed by the  United States Government,
    its agencies or instrumentalities;
 
        (b) Commercial paper rated Prime-1 by Moody's, or A-1 by S&P or unrated,
    but determined by the Sub-Adviser to be of comparable quality;
 
        (c) Bankers acceptances or negotiable certificates of deposit issued  by
    the 25 largest U.S. banks (in terms of deposits); and
 
        (d) Cash and cash equivalents.
 
    DEBT SECURITIES:
 
        (a)  Obligations issued or  guaranteed by the  United States Government,
    its agencies or instrumentalities;
 
        (b) Debt securities which are  rated Aaa, Aa, A,  or Baa by Moody's,  or
    AAA, AA, A or BBB by S&P or unrated, but determined by the Sub-Adviser to be
    of comparable quality;
 
        (c)  Obligations (payable  in U.S.  dollars) of,  or guaranteed  by, the
    Government of Canada or  of a Province of  Canada or any instrumentality  or
    political subdivision thereof.
 
    The  Fund may engage  in the options and  futures strategies described under
"Certain Investment Strategies and Policies".
 
    The debt securities in which the Fund may invest are considered  "investment
grade"  in that they  are generally suitable for  purchase by prudent investors.
However, the  lowest  category of  investment  grade securities  (rated  Baa  by
Moody's  or BBB by S&P) may  have speculative characteristics, such that changes
in economic  conditions or  other circumstance  are  more likely  to lead  to  a
weakened  capacity to make principal  and interest payments than  is the case of
debt securities  with higher  ratings. The  portfolio of  the Fund  is  actively
managed  by AAM, as Sub-Adviser, in order  to anticipate events leading to price
or ratings changes. If the rating of a security falls below investment grade, or
an unrated  security  is deemed  to  have  fallen below  investment  grade,  AAM
analyzes  relevant economic and market data in making a determination of whether
to retain or dispose of the investment. The performance of the securities in the
portfolio is  monitored  continuously,  and  they  are  purchased  and  sold  as
conditions warrant and permit.
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the  Fund  was  126%.  The  portfolio  turnover  rate  exceeded  100%  due  to a
restructuring of the Fund's  mortgage-backed securities. The portfolio  turnover
rate  for the Fund may vary greatly from year to year. A high portfolio turnover
rate may result in greater brokerage costs to the Fund.
    
 
   
    See the Appendix  to the  Prospectus for an  explanation of  the ratings  of
Moody's and S&P.

GOVERNMENT BOND FUND
 
    INVESTMENT   OBJECTIVE:    The  Government  Bond  Fund  seeks  high  income,
preservation  of  capital  and   maintenance  of  liquidity  primarily   through
investments  in debt instruments issued or  guaranteed by the U.S. Government or
its agencies or instrumentalities ("U.S. Government securities") and in  related
options,  futures and repurchase  agreements. Under normal  conditions, at least
80% of the Fund's assets will be invested in U.S. Government securities.
 
    SUB-ADVISER:  AAM  serves as Sub-Adviser  to the Government  Bond Fund.  See
"Equity Index Fund" for more information about AAM.
 
    INVESTMENT  POLICIES:   Some  U.S. Government  securities, such  as Treasury
bills, notes and bonds, which differ  only in their interest rates,  maturities,
and  times of issuance, are supported by the full faith and credit of the United
States. Other U.S. Government securities are  supported by (i) the right of  the
issuer  to borrow  from the U.S.  Treasury; (ii) discretionary  authority of the
U.S. Government to purchase the obligations of the agency or instrumentality  or
(iii)  only the credit of the instrumentality itself. No assurances can be given
that the  U.S. Government  would provide  financial support  to U.S.  Government
sponsored instrumentalities if it is not obligated to do so by law. The Fund may
invest   in  mortgage-backed   government  securities,   including  pass-through
securities and participation  certificates of the  Government National  Mortgage
Association ("Ginnie Mae"), the Federal Home Loan Mortgage Corporation ("Freddie
Mac") and the Federal National Mortgage Association ("Fannie Mae").
 
   
    The  Government  Bond Fund  may invest  in any  other security  or agreement
collateralized or otherwise secured by U.S. Government securities. The Fund  may
also invest in separately traded principal and interest components of securities
guaranteed  or  issued  by  the  U.S. Treasury  if  such  components  are traded
independently under the Separate Trading of Registered Interest and Principal of
Securities program. The Fund may enter into repurchase agreements, and may  from
time   to  time  have  temporary  investments  in  short-term  debt  obligations
(including certificates of  deposit, bankers acceptances  and commercial  paper)
pending the making of other investments or for liquidity purposes.
    
 
    The Government Bond Fund may engage in several active management strategies,
including  the lending of portfolio  securities, forward commitment purchases of
securities, writing  covered call  and covered  put options  on U.S.  Government
securities,  purchasing such  call and  put options,  and entering  into closing
purchase and sale transactions. The Fund  may engage in the options and  futures
strategies described under "Certain Investment Strategies and Policies".
 
   
    U.S.  Government securities may  be purchased or sold  without regard to the
length of time they have  been held to attempt  to take advantage of  short-term
differentials  in yields, with the objective  of seeking income while conserving
capital. While short-term trading  increases portfolio turnover, the  Government
Bond  Fund incurs little  or no brokerage costs  for U.S. Government securities.
For the fiscal year ended December 31, 1995, the portfolio turnover rate for the
Fund was 180%. The portfolio turnover rate  for the Fund increased from 106%  in
1994  due  to  a  restructuring of  the  Fund's  mortgage-backed  securities. In
addition, U.S. Treasury  securities were sold  to fund the  purchase of  various
asset-backed securities.
    
 
MONEY MARKET FUND
 
    INVESTMENT OBJECTIVE:  The Money Market Fund seeks to obtain maximum current
income consistent with preservation of capital and liquidity.
 
    SUB-ADVISER:    AAM serves  as  Sub-Adviser to  the  Money Market  Fund. See
"Equity Index Fund" for more information about AAM.
 
                                       20
<PAGE>
    INVESTMENT POLICIES:  The Fund seeks  to achieve its objective by  investing
in the following high quality money market instruments:
 
        (a)  Obligations issued or  guaranteed by the  United States Government,
    its agencies or instrumentalities;
 
        (b) Commercial paper which meets  the ratings requirements as set  forth
    in the paragraph below;
 
        (c)  Obligations  of banks  or savings  and  loan associations  (such as
    bankers acceptances and certificates of deposit, including
    dollar-denominated  obligations   of   foreign  branches   of   U.S.   banks
    ("Eurodollars") and U.S. branches of foreign banks if such U.S. branches are
    subject   to  state  banking  requirements  and  Federal  Reserve  reporting
    requirements) which at the date of the investment have deposits of at  least
    $1 billion as of their most recently published financial statements;
 
        (d)  Repurchase agreements  with respect to  obligations described under
    (a) above  (such  obligations  subject  to  repurchase  agreement  may  bear
    maturities   of  more  than  one  year).  For  more  information  concerning
    repurchase agreements, see "Certain Investment Strategies and Policies."
 
        (e) Cash and cash equivalents.
 
   
    The Money Market Fund will not purchase any security unless (i) the security
has received the highest  quality rating by at  least two nationally  recognized
statistical  rating organizations  ("NRSROs") or  by one  NRSRO if  only one has
rated the security, or (ii) the security  is unrated and in the opinion of  AAM,
as  Sub-Adviser, in accordance with guidelines adopted  by the Trustees, is of a
quality comparable to the  highest rating of an  NRSRO. These standards must  be
satisfied  at the time an  investment is made. If  the quality of the investment
later declines, the Fund may continue  to hold the investment, but the  Trustees
will  evaluate whether the  security continues to  present minimal credit risks.
See the Appendix for an explanation of the ratings of NRSRO ratings.
    
 
    The Fund will limit its portfolio investments to securities with a remaining
maturity of  397  days as  of  the time  of  purchase, in  accordance  with  the
Trustees'  guidelines.  The  portfolio  will  be managed  so  as  to  maintain a
dollar-weighted maturity of 90 days or less.  In order to maximize the yield  on
its  assets,  the Fund  intends  to be  as  fully invested  at  all times  as is
reasonably practicable.
 
    There is always the risk  that the issuer of  an instrument maybe unable  to
make payment upon maturity.
 
                          MANAGEMENT FEES AND EXPENSES

    The  Manager will voluntarily reimburse its  fees and any expenses above the
expense limitations. The expense limitations are voluntary and may be removed at
any time after a Fund's first fiscal year of operations without prior notice  to
existing  shareholders.  For  the  year ended  December  31,  1995,  the Manager
voluntarily agreed  to reimburse  the Select  Capital Appreciation  Fund in  the
amount  of $8,720.  The Manager reserves  the right  to recover from  a Fund any
fees, within a current  fiscal year period, which  were reimbursed in that  same
year  to the  extent that  total annual expenses  did not  exceed the applicable
expense limitation.  Non-recurring  and  extraordinary  expenses  are  generally
excluded  in the determination  of expense ratios  of the Funds  for purposes of
determining any required  expense reimbursement.  Quotations of  yield or  total
return  for any period when  an expense limitation is  in effect will be greater
than if the limitation had not been in effect.

    prior to joining AAM in May 1995.
    
 
                             HOW ARE SHARES VALUED?
 
    The net asset value of the shares  of each Fund is determined once daily  as
of  the close  of the New  York Stock Exchange  (the "Exchange") on  each day on
which the Exchange is open for trading.
 
    Equity securities are valued on the  basis of their market value, if  market
quotations  are readily available. In other cases, they are valued at their fair
value as  determined  in  good  faith  by  the  Trustees,  although  the  actual
calculations may be by persons acting pursuant to the direction of the Trustees.
Debt  securities (other than short-term obligations)  are normally valued on the
basis of  valuations  formulated  by  a  pricing  service  which  utilizes  data
processing  methods  to  determine  valuations  for  normal,  institutional-size
trading units  of  such securities.  Such  methods  include the  use  of  market
transactions   for  comparable  securities  and  various  relationships  between
securities  which  are  generally  recognized  by  institutional  traders.   All
securities  of  the  Money  Market  Fund  are  valued  at  amortized  cost. Debt
obligations in the other Funds  having a remaining maturity  of 60 days or  less
are  valued  at  amortized  cost  when  it  is  determined  that  amortized cost
approximates fair  value. Short-term  obligations of  the other  Funds having  a
remaining  maturity of more than 60 days are marked to market based upon readily
available market quotations for such obligations or similar securities.
 
                                       26
<PAGE>
    Unlike the Money Market Fund, which attempts to maintain a stable net  asset
value, the net asset value of the other Funds will fluctuate.
 
                    TAXES AND DISTRIBUTIONS TO SHAREHOLDERS
 
   
    It  is the policy of the Trust to comply with the provisions of the Internal
Revenue Code applicable to regulated investment companies so that the Trust will
not be subject to federal income tax on any net income and any capital gains  to
the  extent  they are  distributed or  are  deemed to  have been  distributed to
shareholders. Dividends out of net investment  income will be declared and  paid
quarterly  in the case of the Growth Fund, Select Growth and Income Fund, Equity
Index Fund, Investment Grade Income Fund  and Government Bond Fund; annually  in
the case of the Select International Equity Fund, Select Aggressive Growth Fund,
Select  Capital Appreciation Fund, Small Cap Value Fund, and Select Growth Fund;
and daily in the  case of the  Money Market Fund.  Distributions of net  capital
gains,  if any, for the  year are made annually.  All dividends and capital gain
distributions are applied to purchase additional Fund shares at net asset  value
as  of the payment date.  Fund shares are held by  the Separate Accounts and any
distributions  are  automatically  reinvested  by  the  Separate  Accounts.  Tax
consequences  to investors  in the Separate  Accounts which are  invested in the
Trust are described in the prospectuses for such Accounts.
    
 
                         SALE AND REDEMPTION OF SHARES
 
   
    Shares of the Funds are sold in  a continuous offering and currently may  be
purchased  only by Separate Accounts of First Allmerica or its subsidiaries. The
Separate Accounts are the funding mechanisms for variable annuity contracts. The
Separate Accounts invest in shares of one  or more of the Funds. Shares of  each
Fund  are sold at  their net asset value  as next computed  after receipt of the
purchase order without the addition of  any selling commission or "sales  load".
The  Distributor,  Allmerica  Investments,  Inc., at  its  expense,  may provide
promotional incentives to dealers that sell variable annuity contracts for which
the Funds serve as investment vehicles.
    
 
   
    Shares  of  the  Trust  are  also  currently  being  issued  under  separate
prospectuses  to  Separate  Accounts  of  Allmerica  Life,  First  Allmerica and
subsidiaries of First Allmerica which  issue variable or group annuity  policies
or  variable premium life insurance policies ("mixed funding"). Although neither
Allmerica Life  nor  the  Trust  currently  foresees  any  disadvantage,  it  is
conceivable  that in  the future such  mixed funding may  be disadvantageous for
variable or  group  annuity  policyowners or  variable  premium  life  insurance
policyowners  ("Policyowners").  The Trustees  of  the Trust  intend  to monitor
events  in  order  to  identify  any  conflicts  that  may  arise  between  such
Policyowners  and to determine what action, if  any, should be taken in response
thereto. If  the  Trustees  were  to conclude  that  separate  funds  should  be
established  for variable annuity  and variable premium  life separate accounts,
Allmerica Life will pay the attendant expenses.
    
 
    The Trust redeems  shares of  each Fund  at their  net asset  value as  next
computed  after receipt of the request  for redemption. The redemption price may
be more or less than the shareholder's cost.  No fee is charged by the Trust  on
redemption. The variable contracts funded through the Separate Accounts are sold
subject  to  certain fees  and charges  which may  include sales  and redemption
charges, described in the Prospectuses for such Separate Accounts.
 
    Redemption payments will  be paid  within seven  days after  receipt of  the
written  request therefor by the Trust, except  that the right of redemption may
be suspended  or payments  postponed whenever  permitted by  applicable law  and
regulations.
 
                         HOW IS PERFORMANCE DETERMINED?
 
    The  Funds' performance may  be quoted in  advertising. A Fund's performance
may be compared to the performance of other investments or relevant indices. All
performance information is based  on historical results and  is not intended  to
indicate future performance.
 
                                       27
<PAGE>
    For  Funds  other  than the  Money  Market  Fund, "yield"  is  calculated by
dividing a Fund's  annualized net investment  income per share  during a  recent
30-day  period by the net asset value per  share on the last day of that period.
For the Money Market Fund, "yield" represents an annualization of the change  in
value  of  an investment  (excluding  any capital  changes)  in the  Fund  for a
specific seven-day period; "effective yield" compounds that yield for a year and
is, for that reason, greater than the Fund's yield.
 
    Total returns are based on the overall dollar or percentage change in  value
of  a hypothetical investment in a Fund  assuming all dividends and capital gain
distributions are  reinvested.  Cumulative  total  return  reflects  the  Fund's
performance  over a stated period of  time. Average annual total return reflects
the hypothetical annually compounded  return that would  have produced the  same
cumulative  return if the  Fund's performance had been  constant over the entire
period. Because average  annual returns  tend to  smooth out  variations in  the
Fund's return, they are not the same as actual year-by-year results.
 
    YIELDS  AND  TOTAL  RETURNS  QUOTED  FOR THE  FUNDS  INCLUDE  THE  EFFECT OF
DEDUCTING THE  FUND'S  EXPENSES,  BUT  MAY  NOT  INCLUDE  CHARGES  AND  EXPENSES
ATTRIBUTABLE TO A PARTICULAR INSURANCE PRODUCT. SINCE SHARES OF THE FUNDS CAN BE
PURCHASED  ONLY THROUGH A  VARIABLE ANNUITY CONTRACT  OR VARIABLE LIFE CONTRACT,
YOU SHOULD  CAREFULLY  REVIEW  THE  PROSPECTUS FOR  THE  SEPARATE  ACCOUNTS  FOR
INFORMATION  ON RELEVANT  CHARGES AND EXPENSES.  INCLUDING THESE  CHARGES IN THE
QUOTATIONS OF  THE  FUNDS' YIELD  AND  TOTAL RETURN  WOULD  HAVE THE  EFFECT  OF
DECREASING  PERFORMANCE. PERFORMANCE  INFORMATION FOR  THE FUNDS  MUST ALWAYS BE
ACCOMPANIED BY, AND BE REVIEWED  WITH, PERFORMANCE INFORMATION FOR THE  SEPARATE
ACCOUNTS WHICH INVEST IN THE FUNDS.
 
                  ORGANIZATION AND CAPITALIZATION OF THE TRUST
 
   
    The  Trust was established as a  Massachusetts business trust under the laws
of Massachusetts by an Agreement and Declaration of Trust dated October 11, 1984
(the "Trust Declaration"). A copy of the  Trust Declaration is on file with  the
Secretary of the Commonwealth of Massachusetts.
    
 
    The  Trust  has  an  unlimited authorized  number  of  shares  of beneficial
interest which may be divided into an unlimited number of series of such shares,
and which  are  presently divided  into  twelve  series of  shares,  one  series
underlying each Fund. The Select Income Fund is not included in this Prospectus.
The  Trust's shares are entitled to one vote per share (with proportional voting
for fractional shares). The rights  accompanying Fund shares are legally  vested
in  the Separate Accounts. As  a matter of policy,  however, holders of variable
premium life insurance or variable annuity contracts funded through the Separate
Accounts have the  right to  instruct the Separate  Accounts as  to voting  Fund
shares  on all matters to be voted on by Fund shareholders. Voting rights of the
participants  in  the  Separate  Accounts  are  more  fully  set  forth  in  the
prospectuses  or offering circular relating to those Accounts. See "Organization
of  the  Trust"  in  the  SAI  for  the  definition  of  a  "majority  vote"  of
shareholders.
 
    The  Trust  is not  required to  hold annual  meetings of  shareholders. The
Trustees or shareholders holding at least 10% of the outstanding shares may call
special meetings of shareholders.
 
   
FUND RECORDKEEPING AGENT
    
 
   
    First Data, a wholly-owned subsidiary of First Data Corporation,  calculates
net  asset value  per share  and maintains  general accounting  records for each
Fund. First Data is entitled to  receive an annual Fund recordkeeping fee  based
on Fund assets and certain out-of-pocket expenses.
    
 
CUSTODIAN
 
   
    Bankers  Trust Company, 130 Liberty Street, New York, New York 10006, is the
Custodian of the securities and other assets of the Trust.

                            INVESTMENT RESTRICTIONS
 
    The following is a description of certain investment restrictions which  are
fundamental  and may not be  changed with respect to  a Fund without shareholder
approval. For a description of certain other investment restrictions,  reference
should be made to the SAI.
 
        1.   No Fund will concentrate  its investments in particular industries,
    including debt obligations of foreign governments, but a Fund may invest  up
    to  25%  of the  value of  its total  assets in  a particular  industry. The
    restriction  does  not  apply  to  investments  in  obligations  issued   or
    guaranteed   by   the   United   States   of   America,   its   agencies  or
    instrumentalities, or to investments by the Money Market Fund in  securities
    issued or guaranteed by domestic branches of U.S. banks.
 
        2.   As  to 75% of  the value  of its total  assets (100%  for the Money
    Market Fund), no Fund  will invest more  than 5% of the  value of its  total
    assets  in the securities of any one issuer (other than securities issued by
    or guaranteed as to principal or interest by the United States Government or
    any agency  or instrumentality  thereof) or  acquire more  than 10%  of  the
    voting securities of any issuer. The remaining 25% of assets (other than for
    the  Money Market  Fund) may be  invested in  the securities of  one or more
    issuers without regard to such limitations.
 
   
    These limitations apply as of the time of purchase. If through market action
the percentage limitations are exceeded, the Fund will not be required to reduce
the amount of its holding in such investments.
    
 
                   CERTAIN INVESTMENT STRATEGIES AND POLICIES
 
REPURCHASE AGREEMENTS (APPLICABLE TO ALL FUNDS) AND REVERSE REPURCHASE
AGREEMENTS (APPLICABLE TO THE SELECT CAPITAL APPRECIATION FUND)
 
    Each Fund may invest in repurchase agreements, under which the Fund acquires
ownership of a security (ordinarily  U.S. Government securities) but the  seller
agrees,  at the time of sale, to purchase the security at a mutually agreed upon
time and price. Should any seller  of a repurchase agreement fail to  repurchase
the  underlying security, or should any seller become insolvent or involved in a
bankruptcy  proceeding,  a  Fund  could  incur  costs  and  losses.   Repurchase
Agreements  maturing in  more than seven  days are  subject to the  15% limit on
illiquid securities.
 
   
    When the Select Capital  Appreciation Fund invests  in a reverse  repurchase
agreement,   it  sells  a  security  to  another  party  such  as  a  banker  or
broker-dealer, in return  for cash, and  agrees to  buy the security  back at  a
future date and price. Reverse repurchase agreements may be used to provide cash
to  satisfy  unusually  heavy  redemption requests  or  for  other  temporary or
emergency purposes without the necessity  of selling portfolio securities or  to
earn  additional  income on  portfolio securities,  such  as treasury  bills and
notes.
    
 
"WHEN-ISSUED" SECURITIES (APPLICABLE TO ALL FUNDS)
 
    Each Fund  may purchase  securities  on a  when-issued or  delayed  delivery
basis.  Delivery  and  payment normally  take  place  15 to  45  days  after the
commitment to purchase.  No income  accrues on when-issued  securities prior  to
delivery.  Purchase  of when-issued  securities  involves the  risk  that yields
available in the market when delivery occurs may be higher than those  available
when  the when-issued order is placed resulting in a decline in the market value
of the  security. There  is also  the  risk that  under some  circumstances  the
purchase of when-issued securities may act to leverage the Fund.
 
LENDING OF SECURITIES (APPLICABLE TO ALL FUNDS)
 
   
    For the purpose of realizing additional income, the Funds may lend portfolio
securities  to broker-dealers  or financial  institutions amounting  to not more
than 30% of their respective total assets taken at current value. While any such
loan is  outstanding, a  Fund will  continue  to receive  amounts equal  to  the
interest  or dividends paid by the issuer on the securities, as well as interest
(less any  rebates  to  be paid  to  the  borrower) on  the  investment  of  the
collateral or a fee from the borrower. Each Fund will
    
 
                                       29
<PAGE>
have  the right to call  each loan and obtain  the securities. Lending portfolio
securities involves  certain  risks,  including  possible  delays  in  receiving
additional  collateral or in the recovery of  the securities or possible loss of
rights in the  collateral should the  borrower fail financially.  Loans will  be
made in accordance with guidelines established by the Board of Trustees.
 
FOREIGN SECURITIES (APPLICABLE TO EACH FUND EXCEPT THE SMALL CAP VALUE FUND,
INVESTMENT GRADE INCOME FUND, GOVERNMENT BOND FUND AND MONEY MARKET FUND)
 
    Investments  in  foreign  markets involve  substantial  risks  not typically
associated with investing in  the U.S. which should  be carefully considered  by
the  investor.  Such  risks  may  include  political  and  economic instability,
differing accounting and financial reporting standards, higher commission  rates
on  foreign portfolio  transactions, less  readily available  public information
regarding issuers,  potential  adverse  changes  in  tax  and  exchange  control
regulations  and the  potential for  restrictions on  the flow  of international
capital. Foreign  securities  also  involve  currency  risks.  Accordingly,  the
relative  strength  of  the  U.S.  dollar may  be  an  important  factor  in the
performance of  that  Fund,  depending  on the  extent  of  the  Fund's  foreign
investments.  Some  foreign  securities exchanges  may  not be  as  developed or
efficient as  those in  the U.S.  and securities  traded on  foreign  securities
exchanges  are generally subject to greater  price volatility. There is also the
possibility of adverse  changes in investment  or exchange control  regulations,
expropriation  or confiscatory taxation and limitations  on the removal of funds
or other assets. Investments in emerging countries involve exposure to  economic
structures  that are generally less diverse and  mature than in the U.S., and to
political systems which may be less  stable. In addition, securities of  issuers
located  in emerging countries may have limited marketability and may be subject
to more abrupt or erratic price fluctuations.
 
    Each Fund, except the  Small Cap Value Fund,  Investment Grade Income  Fund,
Government  Bond Fund and Money Market Fund,  may buy or sell foreign currencies
and foreign  currency  forward  contracts, options  on  foreign  currencies  and
foreign   currency  futures   contracts  and  options   thereon.  Although  such
instruments may reduce the  risk of loss due  to a decline in  the value of  the
currency  that is  sold, they  also limit any  possible gain  which might result
should the  value  of the  currency  increase.  Such instruments  will  be  used
primarily  to protect  the Fund from  adverse currency  movements; however, they
also involve the risk that anticipated currency movements will not be accurately
predicted, thus adversely affecting  the Fund's total  return. See "Options  and
Futures Transactions."
 
    The  Funds' investments may include ADRs. For many foreign securities, there
are U.S.  dollar-denominated ADRs  which  are traded  in  the United  States  on
exchanges or over the counter. ADRs represent the right to receive securities of
foreign issuers deposited in a domestic bank or a correspondent bank. An ADR may
be  sponsored by  the issuer of  the underlying  foreign security, or  it may be
issued in unsponsored form. The holder of  a sponsored ADR is likely to  receive
more  frequent and extensive financial  disclosure concerning the foreign issuer
than the holder of an unsponsored ADR and will generally bear lower  transaction
charges. Each Fund may invest in both sponsored and unsponsored ADRs. The Select
International  Equity Fund  and the  Select Capital  Appreciation Fund  also may
utilize EDRs, which are designed for use in European securities markets and also
may invest in GDRs.
 
OPTIONS AND FUTURES TRANSACTIONS (APPLICABLE TO EACH FUND EXCEPT THE SMALL CAP
VALUE FUND AND MONEY MARKET FUND) AND FORWARD CONTRACTS AND SWAPS (APPLICABLE TO
THE SELECT CAPITAL APPRECIATION FUND)
 
    Through the writing and purchase of put and call options on its  securities,
financial  indices and foreign  currencies and the purchase  and sale of futures
contracts and related options with respect to securities, financial indices  and
(in  the case  of the  Select Capital  Appreciation Fund)  foreign currencies in
which it may invest, each Fund except the Money Market Fund and Select Cap Value
Fund may at times seek  to hedge against fluctuations  in net asset value.  Each
Fund's  ability to engage in  options and futures strategies  will depend on the
availability   of    liquid    markets    in    such    instruments.    It    is
 
                                       30
<PAGE>
impossible  to predict the amount of trading  interest that may exist in various
types of options or futures contracts.  Therefore, there is no assurance that  a
Fund  will be  able to  utilize these  instruments effectively  for the purposes
stated above.
 
    Additionally, the Select  Capital Appreciation  Fund may  invest in  forward
contracts and swaps which may expose the Fund to additional investment risks and
transaction costs.
 
   
    Risks  inherent in the use of  futures, options, forward contracts and swaps
("derivative instruments") include (1) the risk that interest rates,  securities
prices  and currency  markets will not  move in the  directions anticipated; (2)
imperfect correlation between the price of derivative instruments and  movements
in  the prices of the securities, interest rates or currencies being hedged; (3)
the fact that  skills needed to  use these strategies  are different from  those
needed  to select  portfolio securities;  (4) the  possible absence  of a liquid
secondary market for any particular instrument at any time; and (5) the possible
need to  defer  closing  out  certain hedged  positions  to  avoid  adverse  tax
consequences.
    
 
    The  Fund will purchase futures  and options only on  exchanges or boards of
trade when there appears to be an  active secondary market, but there can be  no
assurance that a liquid secondary market will exist for any futures or option at
any particular time.
 
    In  connection with transactions  in futures and  related options, the Funds
will be  required  to deposit  as  "initial margin"  an  amount of  cash  and/or
securities.  Thereafter, subsequent payments are made  to and from the broker to
reflect changes in the value of the futures contract.
 
    A more  detailed  explanation  of futures,  options,  and  other  derivative
instruments, and the risks associated with them, is included in the SAI.
 
RESTRICTED SECURITIES (APPLICABLE TO THE SELECT INTERNATIONAL EQUITY FUND,
SELECT AGGRESSIVE GROWTH FUND, SELECT CAPITAL APPRECIATION FUND, SELECT GROWTH
FUND, AND SELECT GROWTH AND INCOME FUND)
 
    The  Funds also may purchase fixed-income securities that are not registered
under the Securities Act of 1933 ("1933 Act") ("restricted securities"), but can
be offered and sold to "qualified  institutional buyers" under Rule 144A of  the
1933  Act. However,  each Fund will  not invest more  than 15% of  its assets in
restricted securities (as  defined in  its investment  restrictions) unless  the
Board  of Trustees  determines, based  upon a  continuing review  of the trading
markets for the  specific restricted security,  that such restricted  securities
are  liquid. The Board of  Trustees has adopted guidelines  and delegated to the
Manager the daily function of determining and monitoring liquidity of restricted
securities.  The  Board,  however,  will  retain  sufficient  oversight  and  be
ultimately  responsible  for the  determinations. Since  it  is not  possible to
predict with assurance exactly  how this market  for restricted securities  sold
and  offered under Rule 144A will develop,  the Board will carefully monitor the
Funds' investments  in securities,  focusing on  such important  factors,  among
others, as valuation, liquidity and availability of information. This investment
practice  could have the  effect of increasing  the level of  illiquidity in the
Fund to  the  extent that  qualified  institutional  buyers become  for  a  time
uninterested  in purchasing these restricted securities.  As a result, the Funds
might not be able to sell these  securities when their Sub-Adviser wishes to  do
so,  or might  have to sell  them at less  than fair value.  In addition, market
quotations are less readily available. Therefore,  judgment may at times play  a
greater  role  in valuing  these  securities than  in  the case  of unrestricted
securities.
 
INVESTMENTS IN MONEY MARKET SECURITIES (APPLICABLE TO ALL FUNDS)
 
    Any Fund may hold at  least a portion of its  assets in cash equivalents  or
money  market instruments. There is  always the risk that  the issuer of a money
market instrument may be unable to make payment upon maturity.
 
    The Money Market Fund may hold uninvested cash reserves pending  investment,
during  temporary defensive  periods or if,  in the opinion  of the Sub-Adviser,
suitable securities are not  available for investment.  Securities in which  the
Money  Market Fund may invest may not earn  as high a level of current income as
long-term,  lower  quality  securities  which,  however,  generally  have   less
liquidity, greater market risk and more fluctuation in market value.
 
                                       31
<PAGE>
   
    Pursuant  to  an  exemptive order  granted  by the  Securities  and Exchange
Commission, the  Select Capital  Appreciation Fund  and other  funds advised  by
Janus Capital may transfer daily uninvested cash balances into one or more joint
trading  accounts. Assets  in the joint  trading accounts are  invested in money
market instruments and the proceeds are allocated to the participating funds  on
a pro rata basis.
    
 
HIGH YIELD SECURITIES (APPLICABLE TO THE SELECT CAPITAL APPRECIATION FUND,
SELECT GROWTH FUND AND THE SELECT GROWTH AND INCOME FUND)
 
    Corporate debt securities purchased by the Select Capital Appreciation Fund,
the  Select Growth Fund and  the Select Growth and Income  Fund will be rated at
the time of purchase  B or better  by Moody's or S&P,  or equivalently rated  by
another  NRSRO, or unrated but  believed by the Sub-Adviser  to be of comparable
quality under the guidelines established for  the Funds. The Select Growth  Fund
and  the Select  Growth and Income  Fund may not  invest more than  15% of their
assets and the Select Capital Appreciation Fund may not invest more than 35%  of
its assets at the time of investment in securities rated below Baa by Moody's or
BBB  by S&P, or equivalently rated by  another NRSRO, or unrated but believed by
the Sub-Adviser to be  of comparable quality. Securities  rated B by Moody's  or
S&P  (or  equivalently by  another  NRSRO) are  below  investment grade  and are
considered, on balance, to be predominantly speculative with respect to capacity
to pay interest and repay principal and will generally involve more credit  risk
than securities in the higher rating categories.
 
    Periods  of economic  uncertainty and changes  can be expected  to result in
increased volatility of market prices of lower-rated securities, commonly  known
as "high yield" securities or "junk bonds", and of the asset value of the Select
Capital  Appreciation Fund,  the Select  Growth Fund  and the  Select Growth and
Income  Fund.  Many  issuers  of  high  yield  corporate  debt  securities   are
substantially  leveraged, which  may impair their  ability to  meet debt service
obligations. Also, during an economic  downturn or substantial period of  rising
interest rates, highly leveraged issuers may experience financial stress.
 
    The  lack of a liquid secondary market in certain lower-rated securities may
have an adverse impact on market price and  the ability of a Fund to dispose  of
particular issues when necessary to meet its liquidity needs or in response to a
specific  economic event such as a deterioration in the credit-worthiness of the
issuer. In addition, a less  liquid market may interfere  with the ability of  a
Fund to accurately value high yield securities and, consequently, value a Fund's
assets. Furthermore, adverse publicity and investor perceptions may decrease the
value  and liquidity of  high yield securities.  It is reasonable  to expect any
recession to severely disrupt the market for high yield fixed-income securities,
have an adverse impact on the value of such securities, and adversely affect the
ability of the issuers  of such securities to  repay principal and pay  interest
thereon.  The  market  prices  of  lower-rated  securities  are  generally  less
sensitive to  interest  rate  changes than  higher-rated  investments  but  more
sensitive  to adverse economic or  political changes, or individual developments
specific to the issuer. Periods of economic or political uncertainty and  change
can be expected to result in volatility of prices of these securities.
 
   
    The Funds also may invest in unrated debt securities of foreign and domestic
issuers.  Unrated  debt,  while  not necessarily  of  lower  quality  than rated
securities,  may  not  have  as  broad  a  market.  Sovereign  debt  of  foreign
governments  is generally  rated by country.  Because these ratings  do not take
into account individual factors  relevant to each issue  and may not be  updated
regularly,  the Sub-Adviser may  treat such securities  as unrated debt. Unrated
debt securities and securities with different ratings from more than one  agency
will  be included in the 15% and 35% limits of the Funds as stated above, unless
such Fund's Sub-Adviser deems such securities to be the equivalent of investment
grade securities. See the Appendix for a description of the bond ratings.
    
 
ASSET-BACKED SECURITIES AND MORTGAGE-BACKED SECURITIES (APPLICABLE TO THE
INVESTMENT GRADE INCOME FUND AND GOVERNMENT BOND FUND)
 
    The  Funds  may   purchase  asset-backed  securities,   which  represent   a
participation  in, or  are secured  by and  payable from,  a stream  of payments
generated by particular assets, frequently a pool of
 
                                       32
<PAGE>
   
assets  similar  to  one  another.  Assets  generating  such  payments   include
instruments  such as motor vehicle installment purchase obligations, credit card
receivables and home  equity loans.  Payment of  principal and  interest may  be
guaranteed  for certain amounts and time periods by a letter of credit issued by
a financial  institution unaffiliated  with the  issuer of  the securities.  The
estimated life of an asset-backed security varies with the prepayment experience
of  the underlying debt instruments. The rate of such prepayments, and hence the
life of  the asset-backed  security, will  be primarily  a function  of  current
market  rates, although other economic and demographic factors will be involved.
Under certain interest rates and prepayment  rate scenarios, the Funds may  fail
to  recoup fully their investment in asset-backed securities. Each Fund will not
invest more than 10% of its total assets in asset-backed securities.
    
 
   
    The Funds  also may  invest  in mortgage-backed  securities which  are  debt
obligations  secured by real  estate loans and  pools of loans  on single family
homes,  multi-family  homes,  mobile  homes,  and  in  some  cases,   commercial
properties.  The Funds may acquire securities representing an interest in a pool
of mortgage loans that are issued or guaranteed by a U.S. government agency such
as Ginnie Mae, Fannie Mae and Freddie Mac.
    
 
    Mortgage-backed securities  are in  most cases  "pass-through"  instruments,
through which the holder receives a share of all interest and principal payments
from   the  mortgages   underlying  the  certificate.   Because  the  prepayment
characteristics of the underlying mortgages vary, it is not possible to  predict
accurately  the  average  life  or  realized yields  of  a  particular  issue of
pass-through  certificates.  During   periods  of   declining  interest   rates,
prepayment of mortgages underlying mortgage-backed securities can be expected to
accelerate.  When the mortgage obligations are  prepaid, the Funds reinvests the
prepaid amounts  in  securities, the  yield  of which  reflects  interest  rates
prevailing  at  the  time.  Moreover,  prepayment  of  mortgages  that  underlie
securities purchased at a premium could result in losses.
 
    The Funds  also may  invest  in multiple  class  securities issued  by  U.S.
government  agencies and instrumentalities  such as Fannie  Mae, Freddie Mac and
Ginnie Mae, including  guaranteed collateralized  mortgage obligations  ("CMOs")
and   Real  Estate   Mortgage  Investment  Conduit   ("REMIC")  pass-through  or
participation  certificates,  when   consistent  with   the  Funds'   investment
objective,  policies and  limitations. A  CMO is  a type  of bond  secured by an
underlying pool  of mortgages  or mortgage  pass-through certificates  that  are
structured  to direct  payment on underlying  collateral to  different series or
classes of  obligations.  A  REMIC is  a  CMO  that qualifies  for  special  tax
treatment  under  the Internal  Revenue Code  and  invests in  certain mortgages
principally  secured  by  interests  in   real  property  and  other   permitted
investments.
 
    CMOs  and guaranteed REMIC  pass-through certificates ("REMIC Certificates")
issued by  Fannie  Mae,  Freddie  Mac  and Ginnie  Mae  are  types  of  multiple
pass-through  securities. Investors may purchase beneficial interests in REMICs,
which are known as "regular" interests or "residual" interests. The Funds do not
currently  intend  to   purchase  residual  interests   in  REMICs.  The   REMIC
Certificates   represent  beneficial  ownership  interests  in  a  REMIC  trust,
generally consisting of mortgage loans or Fannie Mae, Freddie Mac or Ginnie  Mae
guaranteed  mortgage pass-through  certificates. The obligations  of Fannie Mae,
Freddie Mac  or  Ginnie  Mae  under  their  respective  guaranty  of  the  REMIC
Certificates  are obligations solely  of Fannie Mae, Freddie  Mac or Ginnie Mae,
respectively.
 
    Fannie Mae  REMIC  Certificates  are  issued and  guaranteed  as  to  timely
distribution  of principal and  interest by Fannie Mae.  In addition, Fannie Mae
will be obligated  to distribute the  principal balance of  each class of  REMIC
Certificates in full, whether or not sufficient fund are otherwise available.
 
    For  Freddie  Mac  REMIC  Certificates, Freddie  Mac  guarantees  the timely
payment of interest, and  also guarantees the payment  of principal as  payments
are  required to be  made on the  underlying mortgage participation certificates
("PCs"). PCs represent undivided interest in specified residential mortgages  or
participation  therein purchases by  Freddie Mac and  placed in a  PC pool. With
respect to
 
                                       33
<PAGE>
principal payments on PCs, Freddie Mac generally guarantees ultimate  collection
of  all principal  of the  related mortgage  loans without  offset or deduction.
Freddie Mac also guarantees timely payment of principal on certain PCs  referred
to as "Gold PCs."
 
    Ginnie  Mae  REMIC Certificates  guarantee the  full  and timely  payment of
interest and principal on each class of securities (in accordance with the terms
of those classes,  as specified  in the related  offering circular  supplement).
This  Ginnie Mae guarantee is backed by the  full faith and credit of the United
States of America.  REMIC Certificates  issued by  Fannie Mae,  Freddie Mac  and
Ginnie  Mae are treated as U.S. government securities for purposes of investment
policies. There  can be  no assurance  that the  United States  government  will
continue  to provide financial support to Fannie  Mae, Freddie Mac or Ginnie Mae
in the future.
 
STRIPPED MORTGAGE-BACKED SECURITIES (APPLICABLE TO THE INVESTMENT GRADE INCOME
FUND AND GOVERNMENT BOND FUND)
 
    The Funds may invest in  Stripped Mortgage-Backed Securities ("SMBS").  SMBS
are derivative multiclass mortgage securities. SMBS may be issued by agencies or
instrumentalities  of  the  U.S. Government  or  by private  originators  of, or
investors in, mortgage loans, including savings and loan associations,  mortgage
banks,  commercial banks, investment  banks and special  purpose entitles of the
foregoing.
 
   
    SMBS  are  usually  structured  with  two  classes  that  receive  different
proportions  of the interest  and principal distributions on  a pool of mortgage
assets. One type of SMBS 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 some  cases
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 a  IO class is extremely sensitive to the
rate of  principal  payments (including  prepayment  on the  related  underlying
mortgage  assets), and a  rapid rate of  principal payments may  have a material
adverse effect on a  portfolio yield to maturity  from these securities. If  the
underlying  mortgage assets  experience greater than  anticipated prepayments of
principal, the Funds may fail to fully recoup their initial investment in  these
securities  even if  the security  is in one  of the  highest rating categories.
Certain SMBS may be deemed "illiquid"  and subject to the Funds' limitations  on
investment in illiquid securities. The market value of the PO class generally is
unusually  volatile in response  to changes in  interest rates. The  yields on a
class of SMBS that receives all or most of the interest from mortgage assets are
generally  higher  than  prevailing  market  yields  in  other   mortgage-backed
securities  because their cash  flow patterns are  more volatile and  there is a
grater risk  that  the  initial  investment will  not  be  fully  recouped.  The
Sub-Adviser  will  seek  to  manage  these  risks  (and  potential  benefits) by
investing in  a  variety  of  such  securities  and  by  using  certain  hedging
techniques.
    
 
HEDGING TECHNIQUES AND INVESTMENT PRACTICES (APPLICABLE TO THE SELECT
INTERNATIONAL EQUITY FUND AND SELECT CAPITAL APPRECIATION FUND)
 
    The  Select International  Equity Fund  and the  Select Capital Appreciation
Fund may employ certain strategies in  order to manage exchange rate risks.  For
example,  the Funds may hedge some or  all of their investments denominated in a
foreign currency against a decline in the value of that currency. The Funds  may
enter  into  contracts  to sell  that  foreign  currency for  U.S.  dollars (not
exceeding the  value of  a Fund's  assets denominated  in that  currency) or  by
participating  in options  or futures  contracts with  respect to  such currency
("position hedge"). The Funds also could hedge that position by selling a second
currency, which  is expected  to  perform similarly  to  the currency  in  which
portfolio  investments  are denominated  for U.S.  dollars ("proxy  hedge"). The
Funds also may enter into a forward  contract to sell the currency in which  the
security is denominated for a second currency that is expected to perform better
relative  to the U.S. dollar if their Sub-Adviser believes there is a reasonable
degree of correlation between movements  in the two currencies  ("cross-hedge").
As  an operational  policy, the  Funds will  not commit  more than  10% of their
assets to the consummation of
 
                                       34
<PAGE>
cross-hedge contracts and will either  cover currency hedging transactions  with
liquid  portfolio securities denominated in the applicable currency or segregate
high-grade, liquid assets in the amount  of such commitments. In addition,  when
the  Funds  anticipate  repurchasing  securities  denominated  in  a  particular
currency, the Funds may enter into a forward contract to purchase such  currency
in exchange for the dollar or another currency ("anticipatory hedge").
 
    These  strategies minimize  the effect of  currency appreciation  as well as
deprecation, but do not protect against a decline in the underlying value of the
hedged security.  In  addition, such  strategies  may reduce  or  eliminate  the
opportunity  to profit from increases in the  value of the original currency and
may adversely impact the Funds' performance if their Sub-Adviser's projection of
future exchange rates is inaccurate.

COMMERCIAL PAPER RATINGS
 
    MOODY'S EMPLOYS THREE DESIGNATIONS,  ALL JUDGED TO  BE INVESTMENT GRADE,  TO
INDICATE  THE  RELATIVE REPAYMENT  CAPACITY OF  RATED  ISSUERS. THE  TWO HIGHEST
DESIGNATIONS ARE AS FOLLOWS:
 
        Issuers rated  Prime-1  (or  related  supporting  institutions)  have  a
    superior  capacity  for  repayment  of  short-term  promissory  obligations.
    Prime-1 repayment  capacity  will normally  be  evidenced by  the  following
    characteristics:
 
        -- Leading market positions in well-established industries.
 
        -- High rates of return on funds employed.
 
        -- Conservative capitalization structures with moderate reliance on debt
           and ample asset protection.
 
        -- Broad  margins in  earnings coverage  of fixed  financial charges and
           high internal cash generation.
 
        -- Well-established access to a range  of financial markets and  assured
           sources of alternate liquidity.
 
        Issuers rated Prime-2 (or related supporting institutions) have a strong
    capacity  for repayment of short-term  promissory obligations. This normally
    will 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 alternate
    liquidity is maintained.
 
   
    S&P COMMERCIAL PAPER  RATINGS ARE  GRADED INTO  SEVERAL CATEGORIES,  RANGING
FROM  "A-1" FOR THE HIGHEST  QUALITY OBLIGATIONS TO "D"  FOR THE LOWEST. THE TWO
HIGHEST RATING CATEGORIES ARE DESCRIBED AS FOLLOWS:
    
 
   
        A-1 --  This  highest  category  indicates that  the  degree  of  safety
    regarding  timely  payment is  strong.  Those issues  determined  to possess
    extremely strong safety  characteristics are  denoted with a  plus (+)  sign
    designation.
    
 
   
        A-2  -- Capacity for  timely payment on issues  with this designation is
    satisfactory. However, the relative degree of  safety is not as high as  for
    issues designated A-1.
    
 
MUNICIPAL OBLIGATIONS
 
    Moody's  ratings for  state and  municipal and  other short-term obligations
will be  designated Moody's  Investment Grade  ("MIG"). This  distinction is  in
recognition  of  the differences  between short-term  credit risk  and long-term
risk.  Factors  affecting  the  liquidity  of  the  borrower  are  uppermost  in
importance  in  the short-term  borrowing, while  various  factors of  the first
importance in long-term borrowing risk are of lesser importance in the long run.
Symbols used will be as follows:
 
   
        MIG-1 -- This designation denotes best quality. There is present  strong
    protection   by  established  cash  flows,  superior  liquidity  support  or
    demonstrated broad-based access to the market for refinancing.
    
 
   
        MIG-2 -- This  designation denotes high  quality. Margins of  protection
    are ample although not so large as in the preceding group.
    
 
    A  short-term  rating may  also  be assigned  on  an issue  having  a demand
feature. Such ratings will be designated as VMIG to reflect such characteristics
as payment upon  periodic demand rather  than fixed maturity  dates and  payment
relying   on  external  liquidity.  Additionally,   investors  should  be  alert
 
                                       36
<PAGE>
   
to the fact that the source of payment may be limited to the external  liquidity
with  no or limited legal recourse to the issuer in the event that demand is not
met. VMIG-1 and VMIG-2  ratings carry the same  definitions as MIG-1 and  MIG-2,
respectively.
    
 
DESCRIPTION OF MOODY'S BOND RATINGS
 
   
    AAA  -- Bonds that are rated Aaa are  judged to be of the best quality. They
carry the smallest degree  of investment risk and  are generally referred to  as
"gilt  edge". Interest payments are protected by  a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to  impair
the fundamentally strong position of such issues.
    
 
   
    AA  -- Bonds  that are  rated Aa  are judged  to be  of high  quality by all
standards. Together with the Aaa group,  they comprise what are generally  known
as high-grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements  may be  of greater  amplitude or there  may be  other elements present
which make the long-term risks appear somewhat larger than in Aaa securities.
    
 
   
    A -- Bonds that are rated A possess many favorable investment attributes and
are to be considered as upper medium grade obligations. Factors giving  security
to  principal and interest are considered  adequate, but elements may be present
that suggest a susceptibility to impairment some time in the future.
    
 
   
    BAA -- Bonds that are rated Baa are considered as medium grade  obligations,
i.e.,  they are neither  highly protected nor  poorly secured. Interest payments
and principal security appear  adequate for the  present but certain  protective
elements  may be lacking or may  be characteristically unreliable over any great
length of time. Such  bonds lack outstanding  investment characteristics and  in
fact have speculative characteristics as well.
    
 
   
    BA -- Bonds that are rated Ba are judged to have speculative elements; their
future  cannot be considered  as well assured. Often  the protection of interest
and principal payments  may be very  moderate and thereby  not well  safeguarded
during  both  good  and  bad  times over  the  future.  Uncertainty  of position
characterizes bonds in this class.
    
 
   
    B -- Bonds that are rated B generally lack characteristics of the  desirable
investment. Assurance of interest and principal payments or maintenance of other
terms of the contract over any long period of time may be small.
    
 
   
    Those bonds within the Aa, A, Baa, Ba and B categories that Moody's believes
possess  the strongest credit attributes  within those categories are designated
by the symbols Aa1, A1, Baa1, Ba1 and B1.
    
 
   
DESCRIPTION OF S&P'S DEBT RATINGS
    
 
   
    AAA -- Debt rated AAA  has the highest rating  assigned by S&P. Capacity  to
pay interest and repay principal is extremely strong.
    
 
   
    AA  -- Debt rated  AA has a very  strong capacity to  pay interest and repay
principal and differs from AAA issues only in a 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. Where as 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.
    
 
                                       37
<PAGE>
   
    BB,  B, CCC, CC,  C -- Debt  rated BB, B,  CCC, CC, C  is regarded as having
predominantly speculative  characteristics  with  respect  to  capacity  to  pay
interest and repay principal. BB indicates the least degree of speculation and C
the  highest.  While such  debt  will likely  have  some quality  and protective
characteristics, these are outweighed by large uncertainties or major  exposures
to adverse conditions.
    
 
    PLUS (+) OR (-):  The ratings from AA to CCC may be modified by the addition
of a plus or minus sign to show relative standing within the major categories.

    Allmerica  Investment  Trust  (the  "Trust")  is  a  professionally managed,
open-end investment  company  designed  to  provide  the  underlying  investment
vehicles  for insurance related accounts. The investment objectives of the seven
separate portfolios of the Trust (collectively, the "Funds", and,  individually,
the "Fund") currently offered by this Prospectus are as follows:
 
        SELECT  INTERNATIONAL EQUITY  FUND seeks maximum  long-term total return
    (capital appreciation and income) primarily by investing in common stocks of
    established non-U.S. companies.
 
        SELECT AGGRESSIVE GROWTH FUND  seeks above-average capital  appreciation
    by  investing primarily in common stocks  of companies which are believed to
    have significant potential for capital appreciation.
 
        SELECT CAPITAL APPRECIATION FUND seeks long-term growth of capital in  a
    manner consistent with the preservation of capital. Realization of income is
    not  a significant investment  consideration and any  income realized on the
    Fund's investments will be incidental to its primary objective.
 
        SELECT GROWTH  FUND seeks  to  achieve long-term  growth of  capital  by
    investing  in a diversified portfolio  consisting primarily of common stocks
    selected on the basis of their long-term growth potential.
 
        SELECT GROWTH AND INCOME FUND seeks a combination of long-term growth of
    capital  and   current   income.  The   Fund   will  invest   primarily   in
    dividend-paying common stocks and securities convertible into common stocks.
 
        SELECT  INCOME FUND seeks a high level  of current income. The Fund will
    invest primarily in investment grade, fixed-income securities.
 
        MONEY MARKET FUND seeks to obtain maximum current income consistent with
    preservation of capital and liquidity.
 
   
    Currently, shares of each  Fund may only be  purchased by separate  accounts
("Separate  Accounts") established  by First Allmerica  Financial Life Insurance
Company ("First Allmerica")  or Allmerica Financial  Life Insurance and  Annuity
Company  ("Allmerica Life"), a subsidiary of First Allmerica, for the purpose of
funding variable annuity contracts and  variable life insurance policies  issued
by  First Allmerica or Allmerica Life.  The prospectus for the Separate Accounts
should be read in conjunction with this Prospectus.
    
 
   
    This Prospectus sets forth concisely the information about the Trust that  a
prospective   investor  ought  to  know  before  investing.  Certain  additional

                           HOW ARE THE FUNDS MANAGED?
 
   
    The  overall responsibility for the supervision  of the affairs of the Trust
vests in the  Board of  Trustees of  the Trust who  meet on  a quarterly  basis.
Allmerica Investment Management Company, Inc. (the "Manager") is responsible for
the  management  of  the Trust's  day-to-day  business affairs  and  has general
responsibility for the management of the investments of the Funds. The  Manager,
at  its  expense,  has  contracted  with  certain  Sub-Advisers  to  manage  the
investments of the Funds subject to  the requirements of the Investment  Company
Act of 1940 (the "1940").
    
 
   
    The  Manager  is  a  wholly-owned  subsidiary  of  First  Allmerica,  a life
insurance company, which was  organized in Massachusetts  in 1844. The  Manager,
organized  August 19, 1985,  also serves as  manager of the  Allmerica Funds, an
open-end investment company. The Manager and First Allmerica are located at  440
Lincoln Street, Worcester, Massachusetts 01653.
    
 
    The  Manager has entered  into Sub-Adviser Agreements  for the management of
the investments of each of the  Funds. The Sub-Advisers, who have been  selected
on  the basis  of various  factors, including  management experience, investment
techniques and staffing, are each authorized to engage in portfolio transactions
on  behalf  of  the  applicable  Funds  subject  to  such  general  or  specific
instructions  as may be given by the Trustees and/or the Manager. The terms of a
Sub-Adviser Agreement cannot  be materially  changed without the  approval of  a
majority  interest of  the shareholders of  the affected  Fund. The Sub-Advisers
have been selected  by the  Manager and  Trustees in  consultation with  Rogers,
Casey  & Associates  ("Rogers, Casey"), a  leading pension  consulting firm. The
cost of such consultation is borne by the Manager.
 
    Rogers, Casey  provides consulting  services to  pension plans  representing
over  $150 billion in total assets and, in its consulting capacity, monitors the
investment performance  of over  1,000 investment  advisers. From  time to  time
specific  clients of Rogers, Casey  and the Sub-Advisers will  be named in sales
materials.  At  times,  Rogers,  Casey  assists  in  the  development  of  asset
allocation  strategies which may be used  by shareholders in the diversification
of their portfolio across different asset classes.
 
   
    Ongoing  performance  of  the  independent  Sub-Advisers  is  monitored  and
evaluated  by a  committee whose  members may  include senior  officers of First
Allmerica,  its  affiliates  or  the  Manager  and  an  independent  consultant.
Combined,  the committee has over 150 years of investment experience. Historical
performance data for all Funds is set forth in the "Financial Highlights" tables
starting on Page 3.  The Manager is  solely responsible for  the payment of  all
fees to the Sub-Advisers. The Sub-Advisers for each of the Funds are as follows:

and "Fund Manager Information."
    
 
   
    The Manager also has entered into an Administrative Services Agreement  with
First  Data  Investor  Services  Group,  Inc.  ("First  Data"),  a  wholly-owned
subsidiary of First Data Corporation, whereby First Data performs administrative
services for each of the Funds and is entitled to receive an administrative  fee
and  certain out-of-pocket expenses.  The Manager is  solely responsible for the
payment of the administrative fee to First Data.

                WHAT ARE THE INVESTMENT OBJECTIVES AND POLICIES?
 
    Each Fund has a separate investment objective and policies designed to  meet
different  investment  and  financial needs,  as  described below.  There  is no
assurance that a Fund will achieve its investment objective.
 
   
    Each Fund other  than the  Money Market  Fund may invest  up to  15% of  its
assets  in securities which are illiquid because they are subject to restriction
on resale or for which market  quotations are not readily available. The  Select
Aggressive  Growth Fund, Select Growth Fund,  Select Growth and Income Fund, and
Select Income Fund may each invest up to 25% of its assets in foreign securities
(not including its investments in American Depositary Receipts ("ADRs")) and the
Select International Equity Fund  and the Select  Capital Appreciation Fund  may
each  invest any  percentage of its  assets in foreign  securities. See "Certain
Investment Strategies and Policies".  The Select Growth  Fund and Select  Growth
and  Income  Fund  each may  invest  up to  35%  of its  assets  in fixed-income
securities, including  not more  than 15%  in lower-rated  securities,  commonly
known as "junk bonds." The Select Capital Appreciation Fund may invest up to 35%
of  its assets in such lower-rated  securities. Fixed-income securities rated in
the fourth  highest grade  by  Moody's Investors  Service, Inc.  ("Moody's")  or
Standard  & Poor's  Ratings Service, a  division of  McGraw-Hill Companies, Inc.
("S&P"), (Baa and BBB, respectively) are investment grade but are considered  to
have  some speculative  characteristics. Lower-rated securities  or "junk bonds"
(rated Ba/BB or  lower) involve  the risks discussed  under "Certain  Investment
Strategies and Policies".
    
 
    A  Fund's investment objective is fundamental and may not be changed without
shareholder approval. Unless otherwise  indicated, a Fund's investment  policies
are not fundamental and may be changed without shareholder approval.
 
SELECT INTERNATIONAL EQUITY FUND
 
    INVESTMENT  OBJECTIVE:  The  Select International Equity  Fund seeks maximum
long-term total return (capital appreciation and income) primarily by  investing
in common stocks of established non-U.S. companies.
 
   
    SUB-ADVISER:    Bank of  Ireland  Asset Management  (U.S.)  Limited ("BIAM")
serves as  Sub-Adviser for  the Select  International Equity  Fund. BIAM  is  an
indirect  wholly-owned subsidiary of Bank of Ireland. Its main offices are at 26
Fitzwilliam Place, Dublin  2, Ireland.  Its U.S.  offices are  at Two  Greenwich
Plaza,  Greenwich,  CT 06830.  Bank  of Ireland  provides  investment management
services through a network of sister companies, including BIAM which  represents
North  American  clients.  As of  December  31,  1995, Bank  of  Ireland managed
approximately $15  billion  in  global securities  for  Irish,  United  Kingdom,
European and U.S. clients.
    
 
    INVESTMENT  POLICIES:   To achieve  its objective,  the Select International
Equity Fund  will invest  primarily  in common  stocks of  established  non-U.S.
companies.  Under normal  market conditions,  at least  65% of  the Fund's total
assets will be  invested in the  securities of companies  domiciled in at  least
five  foreign  countries, not  including the  United States.  The Fund  may also
acquire fixed-income debt securities. It will do so, at the discretion of  BIAM,
primarily for defensive purposes.
 
    The   Fund's  investments  may  include  ADRs  which  may  be  sponsored  or
unsponsored by  the  underlying  issuer.  The Fund  may  also  utilize  European
Depositary  Receipts  ("EDRs"),  which  are similar  to  ADRs,  in  bearer form,
designed for  use  in  the  European securities  market  and  Global  Depositary
Receipts  ("GDRs"). Investments in foreign securities carry additional risks not
present in domestic securities. See "Certain Investment Strategies and  Policies
- --  Foreign  Securities." The  Fund  may, for  hedging  purposes, engage  in the
options and futures  strategies described under  "Certain Investment  Strategies
and  Policies."  Certain  state  insurance  regulations  may  impose  additional
restrictions on the Fund's holdings of foreign securities.
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the Fund was 24%. The portfolio turnover rate for the Fund may vary greatly from
year to year.

SELECT AGGRESSIVE GROWTH FUND
 
    INVESTMENT OBJECTIVE:  The Select Aggressive Growth Fund seeks above-average
capital appreciation by investing primarily in common stocks of companies  which
are believed to have significant potential for capital appreciation.
 
   
    SUB-ADVISER:    Nicholas-Applegate  Capital  Management  ("NACM")  serves as
Sub-Adviser to the Select Aggressive Growth Fund. NACM is an investment  manager
supervising  accounts with  assets totaling  approximately $29  billion in total
assets as of  December 31, 1995.  NACM's clients are  primarily major  corporate
employee  benefit  funds,  public  employee  retirement  plans,  foundations and
endowment funds, investment companies and individuals. Founded in 1984, NACM  is
located at 600 West Broadway, Suite 2900, San Diego, California 92101.
    
 
    INVESTMENT POLICIES:  Under normal circumstances, at least 65% of the assets
of  the Select  Aggressive Growth  Fund will  be invested  in equity securities,
consisting  of  common  stocks,   securities  convertible  into  common   stocks
(including  bonds, notes and  preferred stocks) and  warrants. The Fund's assets
may also be  invested in other  debt securities and  preferred stocks when  such
securities  are believed appropriate in light of the Fund's investment objective
and market conditions.
 
    The selection of securities is made  solely on the basis of their  potential
for  capital appreciation. Dividend and interest  income, if any, from portfolio
securities is incidental to the  Fund's investment objective. While  investments
may  be made in  well-known and established companies,  a significant portion of
the Fund's investments is expected to  be in securities of newer and  relatively
unseasoned companies or companies which represent new or changing industries.
 
    At  any given point  a substantial portion of  the Fund's equity investments
may be in  securities which are  not listed for  trading on national  securities
exchanges  and, although  publicly traded,  may be  less liquid  than securities
issued by larger,  more seasoned  companies which trade  on national  securities
exchanges.  Up to  15% of  the Fund's  assets may  be invested  in restricted or
illiquid securities.
 
    Securities of newer companies may be closely held with only a small  portion
of their outstanding securities owned by the general public. Newer companies may
have  relatively small revenue, lack depth of  management and have a small share
of the market for their products or services; thus, they may be more  vulnerable
to  changes  in  economic  conditions,  market  fluctuations  and  other factors
affecting the  profitability or  marketability of  companies. Due  to these  and
other  factors, the  price movement of  the securities  held by the  Fund can be
expected to be more volatile than is the case for the market as a whole, and the
net  asset  value  of  a  share   of  the  Fund  may  fluctuate   significantly.
Consequently,  the Fund should not be  considered suitable for investors who are
unable or unwilling to assume the risk of loss inherent in an aggressive  growth
portfolio,  nor  should  investment in  the  Fund  be considered  a  balanced or
complete investment program.
 
   
    When NACM determines  that market conditions  warrant a temporary  defensive
position,  the Fund  may invest  without limitation  in high-grade, fixed-income
securities,  U.S.  Government  securities,  or  hold  assets  in  cash  or  cash
equivalents.  The  Fund may,  for hedging  purposes, engage  in the  options and
futures strategies described under "Certain Investment Strategies and Policies".
    
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the  Fund  was  104%.  The  portfolio   turnover  rate  was  104%  because   the
Sub-Adviser's  investment approach typically  results in above-average portfolio
turnover as securities are  sold when the Sub-Adviser  believes the reasons  for
their  initial purchase are no longer valid or when it believes that the sale of
a security owned by the  Fund and the purchase  of another security can  enhance
return. A security may be sold to avoid a prospective decline in market value or
purchased  in anticipation  of a  market rise.  Although it  is not  possible to
predict future  portfolio turnover  rates accurately,  and such  rates may  vary
greatly  from year to year, NACM  anticipates that the annual portfolio turnover
generally will  not exceed  100%. A  high portfolio  turnover rate  will  likely
result in greater brokerage costs to the Fund.

SELECT CAPITAL APPRECIATION FUND
 
    INVESTMENT  OBJECTIVE:  The Select Capital Appreciation Fund seeks long-term
growth of  capital in  a manner  consistent with  the preservation  of  capital.
Realization  of income  is not  a significant  investment consideration  and any
income realized on  the Fund's  investments will  be incidental  to its  primary
objective.
 
   
    SUB-ADVISER:  Janus Capital Corporation ("JCC") serves as Sub-Adviser to the
Select  Capital Appreciation Fund.  JCC has served as  investment adviser to the
Janus Fund since 1969 and currently serves  as investment adviser to all of  the
Janus  retail funds, as well as adviser or sub-adviser to other mutual funds and
individual, corporate, charitable and retirement accounts. Kansas City  Southern
Industries, Inc. ("KCSI") owns approximately 83% of the outstanding voting stock
of JCC. KCSI is a publicly traded holding company whose primary subsidiaries are
engaged  in transportation and financial services.  As of December 31, 1995, JCC
had approximately $30 billion in total  assets under management. JCC is  located
at 100 Fillmore Street, Denver, Colorado 80206-4923.
    
 
   
    INVESTMENT POLICIES:  The Fund invests in common stocks when the Sub-Adviser
believes  that the  relevant market  environment favors  profitable investing in
those securities. The Fund pursues its objective by normally investing at  least
50%  of  its  equity  assets in  securities  issued  by  medium-sized companies.
Medium-sized companies are  those whose market  capitalizations fall within  the
range  of companies in the S&P MidCap  400 Index (the "MidCap Index"). Companies
whose capitalization falls outside this range after the Fund's initial  purchase
continue to be considered medium-sized companies for the purpose of this policy.
As   of  December   29,  1995,   the  MidCap   Index  included   companies  with
capitalizations between approximately $118 million to $7.5 billion. The range of
the MidCap Index is expected to change on a regular basis. Subject to the  above
policy,  the Fund  may also  invest in  smaller or  large issuers.  Common stock
investments are  selected  in  industries and  companies  that  the  Sub-Adviser
believes  are experiencing favorable demand for their products and services, and
which operate in a favorable competitive environment and regulatory climate. The
Sub-Adviser's analysis and  selection process  focuses on  stocks with  earnings
growth  potential that may not be recognized  by the market. Such securities are
selected solely for their capital growth  potential; investment income is not  a
consideration. Medium-sized companies may suffer more significant losses as well
as realize more substantial growth than larger issues; thus, investments in such
companies tend to be more volatile and somewhat speculative.
    
 
   
    The  selection  criteria for  domestic issuers  apply  equally to  stocks of
foreign issuers.  In addition,  factors such  as expected  levels of  inflation,
government  policies influencing  business conditions, the  outlook for currency
relationships, and  prospects  for  relative economic  growth  among  countries,
regions  or  geographic areas  may  warrant greater  consideration  in selecting
foreign stocks. The Fund  may invest without  limitation in foreign  securities.
The  Fund  may  invest directly  in  foreign securities  denominated  in foreign
currency and  not  publicly traded  in  the United  States.  The Fund  also  may
purchase foreign securities through ADRs, EDRs, GDRs and other types of receipts
or  shares  evidencing  ownership  of  the  underlying  foreign  securities.  In
addition, the Fund may invest  indirectly in foreign securities through  foreign
investment  funds or  trusts (including  passive foreign  investment companies).
Certain state insurance  regulations may impose  additional restrictions on  the
Fund's  holdings of foreign securities.  Investments in foreign securities carry
additional risks not  present in  domestic securities.  See "Certain  Investment
Strategies and Policies -- Foreign Securities."
    
 
    Although  the Fund normally  invests primarily in  common stocks, the Fund's
cash position may increase when the  Sub-Adviser is unable to locate  investment
opportunities  with desirable  risk/ reward  characteristics. The  Fund also may
invest in preferred stocks, warrants, government securities, corporate bonds and
debentures, high-grade commercial  papers, certificates of  deposit, other  debt
securities  or repurchase  agreement or  reverse repurchase  agreements when the
Sub-Adviser perceives an opportunity for capital growth from such securities  or
so that the Fund may receive a return on its idle cash. The Fund also may invest
in  debt securities rated below investment  grade, which involve risks discussed
under "Certain Investment  Strategies and  Policies." When the  Fund invests  in
 
                                       10
<PAGE>
such  securities, investment  income will  increase and  may constitute  a large
portion of  the return  realized by  the Fund  and the  Fund probably  will  not
participate  in market advances  or declines to  the extent that  it would if it
remained fully invested in common stocks.
 
    The Fund may  invest in "special  situations" from time  to time. A  special
situation  arises when, in the  opinion of the Sub-Adviser,  the securities of a
particular issuer will be recognized and  appreciate in value due to a  specific
development  with  respect  to  that  issuer.  Developments  creating  a special
situation might include, among others, a new product or process, a technological
breakthrough, a management  change or  other extraordinary  corporate event,  or
differences  in  market supply  of and  demand for  the security.  Investment in
special situations may carry an  additional risk of loss  in the event that  the
anticipated  development  does  not  occur  or  does  not  attract  the expected
attention.
 
    The Fund may, for hedging purposes, engage in options and futures strategies
and  may  utilize  forward  contracts,  interest  rate  swaps  and  swap-related
products. See "Certain Investment Strategies and Policies."
 
   
    For  the  fiscal  period  April 28,  1995  (commencement  of  operations) to
December 31,  1995,  the portfolio  turnover  rate for  the  Fund was  95%.  The
portfolio turnover rate for the Fund may vary from year to year.
    
 
SELECT GROWTH FUND
 
    INVESTMENT  OBJECTIVE:   The Select Growth  Fund seeks  to achieve long-term
growth of capital by investing  in a diversified portfolio consisting  primarily
of common stocks selected on the basis of their long-term growth potential.
 
   
    SUB-ADVISER:   Provident Investment Counsel ("PIC") serves as Sub-Adviser to
the Select Growth Fund. PIC has been an investment manager for over 40 years. As
of December  31, 1995,  PIC had  assets under  management of  approximately  $18
billion. PIC provides investment advisory services to major corporate retirement
plans, public employee retirement plans, investment companies and foundation and
endowment  funds. PIC,  located at 300  North Lake  Avenue, Pasadena, California
91101, is a wholly  owned subsidiary of United  Asset Management Corporation,  a
Boston-based  professional services holding company listed on the New York Stock
Exchange.
    
 
    INVESTMENT POLICIES:  The Select Growth  Fund seeks to attain its  objective
by  investing in securities of companies that appear to have favorable long-term
growth characteristics.  Potential for  long-term  growth is  the  determinative
factor in the selection of portfolio securities. Although the Fund may invest in
dividend-paying  stocks, the generation of current income is not an objective of
the Fund. Any income that is received  is incidental to the Fund's objective  of
long-term  growth of  capital. When choosing  securities for  the portfolio, the
Sub-Adviser focuses on companies  that display strong financial  characteristics
and earnings growth potential.
 
   
    At  least 65% of the  Fund's assets under normal  conditions will consist of
growth-oriented common stocks.  The Fund  may invest  in common  stock of  large
well-known  companies  as  well  as smaller  growth  companies,  which generally
include companies with a market capitalization of $500 million or less ("Smaller
Growth Companies"). The stocks of Smaller Growth Companies may involve a  higher
degree  of risk than  other types of  securities and the  price movement of such
securities can be expected to be more volatile than is the case of the market as
a whole.  The Fund  may  hold stocks  traded  on one  or  more of  the  national
exchanges  as well as in the over-the-counter markets. Because opportunities for
capital growth may exist not only in new and expanding areas of the economy  but
also in mature and cyclical industries, the Fund's portfolio investments are not
limited  to  any particular  type  of company  or  industry. The  Fund  may also
purchase convertible bonds and preferred stocks, warrants and debt securities if
the Fund's Sub-Adviser believes they would help achieve the Fund's objective  of
long-term growth.
    
 
    The  Fund  may invest  up  to 35%  of its  assets  in both  higher-rated and
lower-rated fixed-income securities in seeking its objective of long-term growth
of capital. The dollar average weighted maturity
 
                                       11
<PAGE>
of the  Fund's  fixed-income securities  will  vary depending  on,  among  other
things,  current market conditions. The Fund may  invest up to 15% of its assets
in lower-rated securities, commonly known  as "junk bonds", which involve  risks
discussed   under  "Certain  Investment  Strategies   and  Policies."  For  more
information concerning the  rating categories of  corporate debt securities  see
the Appendix to the Prospectus.
 
    When  the Sub-Adviser determines that  market conditions warrant a temporary
defensive position,  the  Fund  may invest  without  limitation  in  high-grade,
fixed-income  securities, U.S. Government securities, or  hold assets in cash or
cash equivalents. To the extent the Fund is so invested it is not achieving  its
objective  to the  same degree  as under  normal conditions.  The Fund  may, for
hedging purposes, engage in the  options and futures strategies described  under
"Certain Investment Strategies and Policies".
 
    The  Select Growth Fund's  objective of seeking  long-term growth of capital
means that its  assets generally will  be subject  to greater risk  than may  be
involved in investing in securities that are not selected for growth potential.
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the Fund was 51%. The portfolio turnover for the Fund may vary greatly from year
to year.
    
 
SELECT GROWTH AND INCOME FUND
 
    INVESTMENT OBJECTIVE:  The Select Growth and Income Fund seeks a combination
of  long-term  growth  of  capital  and current  income.  The  Fund  will invest
primarily in  dividend-paying  common  stocks and  securities  convertible  into
common stocks.
 
   
    SUB-ADVISER:  John A. Levin & Co., Inc. ("JAL") serves as Sub-Adviser to the
Select  Growth and  Income Fund.  JAL was founded  as a  Delaware corporation in
1982. Currently, shares of  the corporation are held  by six key employees.  The
firm  had approximately $5.6  billion in assets under  management as of December
31, 1995. JAL's clients include U.S.  and foreign individuals and their  related
trust  and charitable organizations; pooled funds for individuals and university
endowments; and pension and profit sharing funds. JAL has entered into a  merger
agreement  whereby JAL will become wholly owned  by Baker, Fentress & Company, a
non-diversified closed-end management investment  company, registered under  the
1940  Act. It is contemplated  the merger will be completed  prior to the end of
1996.
    
 
    INVESTMENT POLICIES:    To achieve  its  objective of  long-term  growth  of
capital  and  current income,  the  Select Growth  and  Income Fund  will invest
primarily in  dividend-paying  common  stocks and  securities  convertible  into
common stocks. It may invest in a wide range of equity securities, consisting of
both  dividend-paying and  non-dividend-paying common  stocks, preferred stocks,
securities convertible into common and preferred stocks and warrants. These  may
include  securities  of large  well-known companies  as  well as  Smaller Growth
Companies. The securities of Smaller  Growth Companies involve certain risks  as
described  above under  the "Select Growth  Fund". The Fund  may hold securities
traded  on  one  or  more  of  the   national  exchanges  as  well  as  in   the
over-the-counter  markets. The Fund's  portfolio investments are  not limited to
any particular type  of company or  industry. The Fund  may purchase  individual
stocks  not  presently paying  dividends which  offer opportunities  for capital
growth or  future income  provided  that the  Sub-Adviser believes  the  overall
portfolio  is  appropriately  positioned  to achieve  its  income  objective. To
achieve current income,  the Fund may  invest up to  35% of its  assets in  both
higher-rated  and lower-rated  fixed-income securities, including  not more than
15% in  lower-rated  securities, commonly  known  as "junk  bonds".  In  certain
circumstances,  fixed-income  securities  may  be  purchased  by  the  Fund  for
long-term growth potential.  (However, the  Fund expects  to have  substantially
less  than  35%  of  its  assets invested  in  fixed-income  securities  in most
circumstances.) Lower-rated  fixed-income  securities  involve  risks  discussed
under  "Certain  Investment  Strategies  and  Policies".  For  more  information
concerning the rating categories of  corporate debt securities see the  Appendix
to the Prospectus. The dollar average weighted maturity
 
                                       12
<PAGE>
of  the  Fund's  fixed-income securities  will  vary depending  on,  among other
things, current market conditions. Purchases  and sales of portfolio  securities
are  made at  such times  and in such  amounts as  deemed advisable  in light of
market, economic and other conditions.
 
    When the Sub-Adviser determines that  market conditions warrant a  temporary
defensive  position,  the  Fund  may invest  without  limitation  in high-grade,
fixed-income securities, U.S. Government securities,  or hold assets in cash  or
cash  equivalents. To the extent the Fund is so invested it is not achieving its
objective to  the same  degree as  under normal  conditions. The  Fund may,  for
hedging  purposes, engage in the options  and futures strategies described under
"Certain Investment  Strategies  and Policies".  There  can, of  course,  be  no
assurance  of  growth of  capital  and because  the  Fund invests  a substantial
portion of its assets in common  stocks and other securities which fluctuate  in
value, there is substantial risk of market decline. The Fund's Sub-Adviser seeks
to minimize this risk through detailed analyses of financial markets and issuers
of  equity securities and through investment  in a diversified portfolio of such
securities.
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover for  the
Fund was 112%. The portfolio turnover rate exceeded 100% because the Sub-Adviser
believes  that  as securities  it has  purchased achieve  appropriate valuation,
selling enhances return and  reduces risk. The portfolio  turnover rate for  the
Fund  may vary greatly  from year to  year. A high  portfolio turnover rate will
likely result in greater brokerage costs to the Fund.
    
 
SELECT INCOME FUND
 
    INVESTMENT OBJECTIVE:  The Select Income Fund seeks a high level of  current
income.  The  Fund  will  invest  primarily  in  investment  grade, fixed-income
securities.
 
   
    SUB-ADVISER:  Standish, Ayer & Wood,  Inc. ("SAW") serves as Sub-Adviser  to
the Select Income Fund. SAW was founded in 1933 to provide investment management
services  to high  net worth  individuals and  institutions. As  of December 31,
1995, total  client  assets exceeded  $29.4  billion. SAW  manages  fixed-income
portfolios  for  major  corporate  and  governmental  pension  plans,  financial
institutions and endowment and foundation funds. Through its affiliate, Standish
International Investment  Management  Company, L.P.,  SAW  offers  international
investment  services. SAW is an independent  investment counseling firm owned by
its twenty-three directors who are active with  the firm. SAW is located at  One
Financial Center, Boston, Massachusetts 02111.
    
 
   
    INVESTMENT POLICIES:  Under normal circumstances, at least 65% of the Select
Income  Fund's assets, at the time of investment, will be invested in investment
grade corporate  debt  securities and  securities  issued or  guaranteed  as  to
principal   or   interest   by  the   U.S.   Government  or   its   agencies  or
instrumentalities. Investment grade corporate debt securities are: (a)  assigned
a rating within the four highest grades (Baa/BBB or higher) by either Moody's or
S&P;  (b) equivalently rated by another nationally recognized statistical rating
organization  ("NRSRO");  or  (c)  unrated  securities  but  determined  by  the
Sub-Adviser  to be of comparable quality. Securities rated in the fourth highest
grade (rated Baa  and BBB by  Moody's and S&P,  respectively) are considered  to
have  some  speculative  characteristics.  The  Fund  will  not  invest  in debt
securities rated below  investment grade (Ba/BB  or lower) by  both Moody's  and
S&P.  For more  information concerning the  rating categories  of corporate debt
securities and commercial paper, see the  Appendix to the Prospectus. The  types
of  securities in which the Fund invests  are corporate debt obligations such as
bonds, notes  and debentures,  and obligations  convertible into  common  stock;
"money   market"  instruments,  such  as   bankers  acceptances,  or  negotiable
certificates of  deposit  issued by  the  25 largest  U.S.  banks (in  terms  of
deposits);  commercial paper rated Prime-1 by Moody's or A-1 by S&P; obligations
issued or guaranteed by the U.S. Government, its agencies or  instrumentalities;
asset-backed securities; mortgage-backed securities) and stripped
mortgage-backed  securities. The Fund may also invest in U.S. dollar obligations
of, or guaranteed by, the  government of Canada or a  province of Canada or  any
instrumentality or political subdivision thereof, and U.S. dollar obligations of
supranational  entities such  as the  World Bank,  European Investment  Bank and
African Development Bank. For more information about asset-backed securities and
mortgage-backed securities and stripped  mortgage-backed securites see  "Certain
Investment Strategies and Policies".
    
 
                                       13
<PAGE>
    The  Fund's investments in corporate debt  securities are not limited to any
particular type of company or industry.  The Fund will invest in corporate  debt
obligations  primarily of companies having a  market capitalization of more than
$500 million at the time of investment.
 
   
    The Fund's  dollar  average  weighted  maturity and  the  mix  of  permitted
portfolio  securities as described above will  vary from time to time depending,
among  other  things,  on  current  market  and  economic  conditions  and   the
comparative  yields on instruments  in different sectors,  such as corporate and
Treasuries, and with different maturities. The dollar average weighted  maturity
of  the  portfolio, excluding  money market  instruments,  is expected  to range
between 5 and 20 years under normal market conditions. The Fund may invest up to
35% of its assets in money market instruments under normal conditions.  Although
the  Fund does not invest for  short-term trading purposes, portfolio securities
may be sold from  time to time without  regard to the length  of time they  have
been  held. The  value of  the Fund's  portfolio securities  will generally vary
inversely with changes in prevailing interest rates, declining as interest rates
rise and increasing as rates decline. The  value will also be affected by  other
market  and economic factors.  There is the risk  with corporate debt securities
that the issuers  may not  be able  to meet  their obligations  on interest  and
principal payments.
    
 
    The  Fund  may, for  hedging  purposes, engage  in  the options  and futures
strategies described under "Certain Investment Strategies and Policies".
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the Fund was 131%. The portfolio turnover rate exceeded 100% due to the need  to
make  significant  changes  in the  structure  of the  portfolio's  mortgage and
corporate bond holdings. The portfolio turnover rate for the Fund may vary  from
year  to year. A  high portfolio turnover  rate may result  in greater brokerage
costs to the Fund.
    
 
MONEY MARKET FUND
 
    INVESTMENT OBJECTIVE:  The Money Market Fund seeks to obtain maximum current
income consistent with preservation of capital and liquidity.
 
   
    SUB-ADVISER:  Allmerica Asset Management, Inc. ("AAM") serves as Sub-Adviser
to the Money Market Fund. AAM, a wholly owned subsidiary of First Allmerica, was
incorporated  in  1993  and  is  located  at  440  Lincoln  Street,   Worcester,
Massachusetts  01653.  As of  December 31,  1995,  AAM had  approximately $10.85
billion in assets under  management. AAM serves as  investment adviser to  First
Allmerica's  General Account and  to a number  of affiliated insurance companies
and other affiliated accounts, and as Adviser for Allmerica Securities Trust,  a
closed-end diversified company.
    
 
    INVESTMENT  POLICIES:  The Money Market  Fund seeks to achieve its objective
by investing in the following high quality money market instruments:
 
    (a) Obligations issued or  guaranteed by the  United States Government,  its
agencies or instrumentalities;
 
    (b)  Commercial paper which  meets the ratings requirements  as set forth in
the paragraph below;
 
    (c) Obligations of banks or savings  and loan associations (such as  bankers
acceptances   and   certificates   of   deposit,   including  dollar-denominated
obligations of foreign branches of U.S. banks ("Eurodollars") and U.S.  branches
of foreign banks if such U.S. branches are subject to state banking requirements
and  Federal Reserve reporting requirements) which at the date of the investment
have deposits  of  at least  $1  billion as  of  their most  recently  published
financial statements;
 
    (d)  Repurchase agreements with  respect to obligations  described under (a)
above (such obligations subject to  repurchase agreement may bear maturities  of
more  than one year). For more information concerning repurchase agreements, see
"Certain Investment Strategies and Policies."
 
    (e) Cash and cash equivalents.
 
                                       14
<PAGE>
    The Money Market Fund will not purchase any security unless (i) the security
has received the highest or second highest quality rating by at least two NRSROs
or by one  NRSRO if only  one has rated  the security, or  (ii) the security  is
unrated  and in the opinion of AAM as Sub-Adviser, in accordance with guidelines
adopted by the Trustees, is  of a quality comparable to  one of the two  highest
ratings of an NRSRO. These standards must be satisfied at the time an investment
is  made. If the quality of the investment later declines, the Fund may continue
to hold the  investment, but  the Trustees  will evaluate  whether the  security
continues  to present minimal credit  risks. See the Appendix  for an example of
NRSRO ratings.
 
    The Fund will limit its portfolio investments to securities with a remaining
maturity of  397  days as  of  the time  of  purchase, in  accordance  with  the
Trustees'  guidelines.  The  portfolio  will  be managed  so  as  to  maintain a
dollar-weighted maturity of 90 days or less.  In order to maximize the yield  on
its  assets, the Money Market Fund intends to  be as fully invested at all times
as is reasonably practicable.
 
    There is always the risk that the  issuer of an instrument may be unable  to
make payment upon maturity.
 
                          MANAGEMENT FEES AND EXPENSES
 
    Under  its Management Agreement with the  Trust, the Manager is obligated to
perform certain administrative and management services for the Trust,  furnishes
to the Trust all necessary office space, facilities, and equipment, and pays the
compensation,  if  any, of  officers and  Trustees who  are affiliated  with the
Manager. Other than the expenses specifically  assumed by the Manager under  the
Management  Agreement, all expenses  incurred in the operation  of the Trust are

    The  Manager will voluntarily reimburse its  fees and any expenses above the
expense limitations. The expense  limitations are voluntary  but will remain  in
effect  through the end  of the first full  fiscal year that a  Fund has been in
operation. The  expense  limitations may  be  removed at  any  time  thereafter,
without  prior notice to existing shareholders  (although the Prospectus will be
revised accordingly).  For  the  year  ended  December  31,  1995,  the  Manager
voluntarily  agreed to reimburse the Select Capital Appreciation Fund and Select
Income Fund  in the  amounts of  $8,720 and  $2,547, respectively.  The  Manager
reserves the right to recover from a Fund any fees, within a current fiscal year
period,  which were reimbursed in that same year to the extent that total annual
expenses did not  exceed the  applicable expense  limitation. Non-recurring  and
extraordinary  expenses are generally  excluded in the  determination of expense
ratios  of  the  Funds  for   purposes  of  determining  any  required   expense
reimbursement.  Quotations  of yield  or  total return  for  any period  when an
expense limitation is in effect will be  greater than if the limitation had  not
been in effect.

                             HOW ARE SHARES VALUED?
 
    The net asset value of the shares  of each Fund is determined once daily  as
of  the close  of the New  York Stock Exchange  (the "Exchange") on  each day on
which the Exchange is open for trading.
 
    Equity securities are valued on the  basis of their market value, if  market
quotations  are readily available. In other cases  they are valued at their fair
value as  determined  in  good  faith  by  the  Trustees,  although  the  actual
calculations  may be  made by  persons acting pursuant  to the  direction of the
Trustees. Debt  securities  (other  than short-term  obligations)  are  normally
valued on the basis of valuations formulated by a pricing service which utilizes
data  processing methods to determine  valuations for normal, institutional-size
trading units  of  such securities.  Such  methods  include the  use  of  market
transactions   for  comparable  securities  and  various  relationships  between
securities  which  are  generally  recognized  by  institutional  traders.   All
securities  of  the  Money  Market  Fund  are  valued  at  amortized  cost. Debt
obligations in the other Funds  having a remaining maturity  of 60 days or  less
are  valued  at  amortized  cost  when  it  is  determined  that  amortized cost
approximates fair  value. Short-term  obligations of  the other  Funds having  a
remaining  maturity of more than 60 days are marked to market based upon readily
available market quotations for such obligations or similar securities.
 
    Unlike the Money Market Fund, which attempts to maintain a stable net  asset
value, the net asset value of the other Funds will fluctuate.
 
                    TAXES AND DISTRIBUTIONS TO SHAREHOLDERS
 
   
    It  is the policy of the Trust to comply with the provisions of the Internal
Revenue Code applicable  to regulated  investment companies, so  that the  Trust
will  not be  subject to federal  income tax on  any net income  and any capital
gains to the extent they are distributed or are deemed to have been  distributed
to  shareholders. Dividends  out of net  investment income will  be declared and
paid quarterly in  the case  of the  Select Growth  and Income  Fund and  Select
Income  Fund;  annually in  the case  of the  Select International  Equity Fund,
Select Aggressive  Growth  Fund, Select  Capital  Appreciation Fund  and  Select
Growth  Fund; and daily in  the case of the  Money Market Fund. Distributions of
net capital gains, if  any, for the  year are made  annually. All dividends  and
capital gain distributions are applied to purchase additional Fund shares at net
asset value as of the payment date. Fund shares are
    
 
                                       19
<PAGE>
held by the Separate Accounts and any distributions are automatically reinvested
by  the Separate Account. Tax consequences to investors in the Separate Accounts
which are  invested in  the Trust  are described  in the  prospectuses for  such
Accounts.
 
                         SALE AND REDEMPTION OF SHARES
 
    Shares  of the Funds are sold in  a continuous offering and currently may be
purchased only by Allmerica Select Separate Accounts. The Separate Accounts  are
the  funding mechanisms  for variable  annuity contracts.  The Separate Accounts
invest in shares of one or  more of the Funds. Shares  of each Fund are sold  at
their  net asset  value as  next computed  after receipt  of the  purchase order
without the addition of any selling commission or "sales load". The Distributor,
Allmerica Investments, Inc. at its  expense, may provide promotional  incentives
to  dealers that sell  variable annuity contracts  for which the  Funds serve as
investment vehicles.
 
   
    Shares of the Trust are also currently being issued to Separate Accounts  of
Allmerica  Life, First Allmerica and subsidiaries of First Allmerica which issue
variable or group annuity policies  or variable premium life insurance  policies
("mixed  funding").  Although neither  Allmerica  Life nor  the  Trust currently
forsees any  disadvantage, it  is  conceivable that  in  the future  such  mixed
funding  may be  disadvantageous for variable  or group  annuity policyowners or
variable premium life insurance  policyowners ("Policyowners"). The Trustees  of
the  Trust intend to monitor events in  order to identify any conflicts that may
arise between such Policyowners and to determine what action, if any, should  be
taken  in response thereto. If the Trustees were to conclude that separate funds
should be established for  variable annuity and  variable premium life  separate
accounts, Allmerica Life will pay the attendant expenses.
    
 
    The  Trust redeems  shares of  each Fund  at their  net asset  value as next
computed after receipt of the request  for redemption. The redemption price  may
be  more or less than the shareholder's cost.  No fee is charged by the Trust on
redemption. The variable contracts funded through the Separate Accounts are sold
subject to certain  fees and  charges, which  may include  sales and  redemption
charges, described in the prospectuses for such Separate Accounts.
 
    Redemption  payments will  be paid  within seven  days after  receipt of the
written request therefor by the Trust,  except that the right of redemption  may
be  suspended or  payments postponed  whenever permitted  by applicable  law and
regulations.
 
                         HOW IS PERFORMANCE DETERMINED?
 
    The Funds' performance may  be quoted in  advertising. A Fund's  performance
may be compared to the performance of other investments or relevant indices. All
performance  information is based  on historical results and  is not intended to
indicate future performance.
 
    For Funds  other  than the  Money  Market  Fund, "yield"  is  calculated  by
dividing  a Fund's  annualized net investment  income per share  during a recent
30-day period by the net asset value per  share on the last day of that  period.
For  the Money Market Fund, "yield" represents an annualization of the change in
value of  an  investment (excluding  any  capital changes)  in  the Fund  for  a
specific seven-day period; "effective yield" compounds that yield for a year and
is, for that reason, greater than the Fund's yield.
 
    Total  returns are based on the overall dollar or percentage change in value
of a hypothetical investment in a  Fund assuming all dividends and capital  gain
distributions  are  reinvested.  Cumulative  total  return  reflects  the Fund's
performance over a stated period of  time. Average annual total return  reflects
the  hypothetical annually compounded  return that would  have produced the same
cumulative return if the  Fund's performance had been  constant over the  entire
period.  Because average  annual returns  tend to  smooth out  variations in the
Fund's return, they are not the same as actual year-by-year results.

    YIELDS AND  TOTAL  RETURNS  QUOTED  FOR THE  FUNDS  INCLUDE  THE  EFFECT  OF
DEDUCTING  THE  FUNDS'  EXPENSES,  BUT  MAY  NOT  INCLUDE  CHARGES  AND EXPENSES
ATTRIBUTABLE TO A PARTICULAR INSURANCE PRODUCT. SINCE SHARES OF THE FUNDS CAN BE
PURCHASED ONLY THROUGH A VARIABLE ANNUITY OR VARIABLE LIFE CONTRACT, YOU  SHOULD
CAREFULLY  REVIEW THE  PROSPECTUS FOR THE  SEPARATE ACCOUNTS  FOR INFORMATION ON
RELEVANT CHARGES AND EXPENSES. INCLUDING THESE CHARGES IN THE QUOTATIONS OF  THE
FUNDS'  YIELD AND TOTAL RETURN WOULD  HAVE THE EFFECT OF DECREASING PERFORMANCE.
PERFORMANCE INFORMATION FOR  THE FUNDS  MUST ALWAYS  BE ACCOMPANIED  BY, AND  BE
REVIEWED WITH, PERFORMANCE INFORMATION FOR THE SEPARATE ACCOUNTS WHICH INVEST IN
THE FUNDS.
 
                  ORGANIZATION AND CAPITALIZATION OF THE TRUST
 
    The  Trust was established as a  Massachusetts business trust under the laws
of Massachusetts by an Agreement and Declaration of Trust dated October 11, 1984
(the "Trust Declaration"). A copy of the  Trust Declaration is on file with  the
Secretary of the Commonwealth of Massachusetts.
 
    The  Trust  has  an  unlimited authorized  number  of  shares  of beneficial
interest which may be divided into an unlimited number of series of such shares,
and which  are  presently divided  into  twelve  series of  shares,  one  series
underlying  each  Fund. Five  of the  series are  not available  under Allmerica
Select and are not included in this Prospectus. The Trust's shares are  entitled
to  one vote  per share  (with proportional  voting for  fractional shares). The
rights accompanying Fund shares are legally vested in the Separate Accounts.  As
a  matter  of  policy, however,  holders  of variable  annuity  contracts funded
through the Separate Accounts have the  right to instruct the Separate  Accounts
as  to voting Fund  shares on all matters  to be voted  on by Fund shareholders.
Voting rights of the  participants in the Separate  Accounts are more fully  set
forth  in the prospectuses relating to  those Accounts. See "Organization of the
Trust" in the SAI for a definition of a "majority vote" of shareholders.
 
    The Trust  is not  required to  hold annual  meetings of  shareholders.  The
Trustees or shareholders holding at least 10% of the outstanding shares may call
special meetings of shareholders.
 
   
FUND RECORDKEEPING AGENT
    
 
   
    First  Data, a wholly-owned subsidiary of First Data Corporation, calculates
net asset value  per share  and maintains  general accounting  records for  each
Fund.  First Data is entitled to receive  an annual Fund recordkeeping fee based
on Fund assets and certain out-of-pocket expenses.
    
 
CUSTODIAN
 
   
    Bankers Trust Company, 130 Liberty Street, New York, New York 10006, is  the
Custodian of the investment securities and other assets of the Trust.
    
 
                            INVESTMENT RESTRICTIONS
 
    The  following is a description of certain investment restrictions which are
fundamental and may not  be changed with respect  to a Fund without  shareholder
approval.  For a description of certain other investment restrictions, reference
should be made to the SAI.
 
1.  No Fund will concentrate its investments in particular industries, including
    debt obligations of  supranational entities and  foreign governments, but  a
    Fund  may invest up to 25% of the  value of its total assets in a particular
    industry. The  restriction  does not  apply  to investments  in  obligations
    issued  or  guaranteed by  the  United States  of  America, its  agencies or
    instrumentalities, or to investments by the Money Market Fund in  securities
    issued or guaranteed by domestic branches of U.S. banks.
 
2.  As to 75% of the value of its total assets (100% for the Money Market Fund),
    no  Fund will invest  more than 5% of  the value of its  total assets in the
    securities of any one issuer (other than securities issued by or  guaranteed
    as to principal or interest by the United States Government or any agency or
    instrumentality  thereof) or acquire more than  10% of the voting securities
    of any issuer. The remaining 25% of assets (other than for the Money  Market
    Fund)  may be  invested in  the securities  of one  or more  issuers without
    regard to such limitations.
 
                                       21
<PAGE>
   
    These limitations apply as of the time of purchase. If through market action
the percentage limitations are exceeded, the Fund will not be required to reduce
the amount of its holding in such investments.
    
 
                   CERTAIN INVESTMENT STRATEGIES AND POLICIES
 
REPURCHASE AGREEMENTS (APPLICABLE TO ALL FUNDS) AND REVERSE REPURCHASE
AGREEMENTS (APPLICABLE TO THE SELECT CAPITAL APPRECIATION FUND)
 
    Each Fund may invest in repurchase agreements, under which the Fund acquires
ownership of a security (ordinarily  U.S. Government securities) but the  seller
agrees,  at the time of sale, to purchase the security at a mutually agreed upon
time and price. Should any seller  of a repurchase agreement fail to  repurchase
the  underlying security, or should any seller become insolvent or involved in a
bankruptcy  proceeding,  a  Fund  could  incur  disposition  costs  and  losses.
Repurchase  Agreements maturing in more than seventy days are subject to the 15%
limited on illiquid securities.
 
   
    When the Select Capital  Appreciation Fund invests  in a reverse  repurchase
agreement,   it  sells  a  security  to  another  party  such  as  a  banker  or
broker-dealer, in return  for cash, and  agrees to  buy the security  back at  a
future date and price. Reverse repurchase agreements may be used to provide cash
to  satisfy  unusually  heavy  redemption requests  or  for  other  temporary or
emergency purposes without the necessity  of selling portfolio securities or  to
earn  additional  income on  portfolio securities,  such  as treasury  bills and
notes.
    
 
"WHEN-ISSUED" SECURITIES (APPLICABLE TO ALL FUNDS)
 
    Each Fund  may purchase  securities  on a  when-issued or  delayed  delivery
basis.  Delivery  and  payment normally  take  place  15 to  45  days  after the
commitment to purchase.  No income  accrues on when-issued  securities prior  to
delivery.  Purchase  of when-issued  securities  involves the  risk  that yields
available in the market when delivery occurs may be higher than those  available
when  the when-issued order is placed resulting in a decline in the market value
of the  security. There  is also  the  risk that  under some  circumstances  the
purchase of when-issued securities may act to leverage the Fund.
 
LENDING OF SECURITIES (APPLICABLE TO ALL FUNDS)
 
   
    For the purpose of realizing additional income, the Funds may lend portfolio
securities  to broker-dealers  or financial  institutions amounting  to not more
than 30% of their respective total assets taken at current value. While any such
loan is  outstanding, a  Fund will  continue  to receive  amounts equal  to  the
interest  or dividends paid by the issuer on the securities, as well as interest
(less any  rebates  to  be paid  to  the  borrower) on  the  investment  of  the
collateral  or a fee  from the borrower. Each  Fund will have  the right to call
each loan  and  obtain the  securities.  Lending portfolio  securities  involves
certain  risks, including possible delays  in receiving additional collateral or
in the recovery of the securities or  possible loss of rights in the  collateral
should  the borrower  fail financially.  Loans will  be made  in accordance with
guidelines established by the Board of Trustees.
    
 
FOREIGN SECURITIES (APPLICABLE TO EACH FUND EXCEPT THE MONEY MARKET FUND)
 
    Investments in  foreign  markets  involve substantial  risks  not  typically
associated  with investing in  the U.S. which should  be carefully considered by
the investor.  Such  risks  may  include  political  and  economic  instability,
differing  accounting and financial reporting standards, higher commission rates
on foreign  portfolio transactions,  less readily  available public  information
regarding  issuers,  potential  adverse  changes  in  tax  and  exchange control
regulations and  the potential  for restrictions  on the  flow of  international
capital.  Foreign  securities  also  involve  currency  risks.  Accordingly, the
relative strength  of  the  U.S.  dollar  may be  an  important  factor  in  the
performance  of  that  Fund,  depending  on the  extent  of  the  Fund's foreign
investments. Some  foreign  securities exchanges  may  not be  as  developed  or
efficient  as  those in  the U.S.  and securities  traded on  foreign securities
exchanges are generally subject to greater  price volatility. There is also  the
possibility  of adverse changes  in investment or  exchange control regulations,
expropriation   or    confiscatory    taxation   and    limitations    on    the
 
                                       22
<PAGE>
removal  of funds  or other  assets. Investments  in emerging  countries involve
exposure to economic structures that are generally less diverse and mature  than
in  the U.S., and  to political systems  which may be  less stable. In addition,
securities  of  issuers   located  in  emerging   countries  may  have   limited
marketability and may be subject to more abrupt or erratic price fluctuations.
 
    Each  Fund, except the Money Market Fund, may buy or sell foreign currencies
and foreign  currency  forward  contracts, options  on  foreign  currencies  and
foreign   currency  futures   contracts  and  options   thereon.  Although  such
instruments may reduce the  risk of loss due  to a decline in  the value of  the
currency  that is  sold, they  also limit any  possible gain  which might result
should the  value  of the  currency  increase.  Such instruments  will  be  used
primarily  to protect  the Fund from  adverse currency  movements; however, they
also involve the risk that anticipated currency movements will not be accurately
predicted, thus adversely affecting  the Fund's total  return. See "Options  and
Futures Transactions."
 
    The  Funds' investments may include ADRs. For many foreign securities, there
are U.S.  dollar-denominated ADRs  which  are traded  in  the United  States  on
exchanges or over the counter. ADRs represent the right to receive securities of
foreign issuers deposited in a domestic bank or a correspondent bank. An ADR may
be  sponsored by  the issuer of  the underlying  foreign security, or  it may be
issued in unsponsored form. The holder of  a sponsored ADR is likely to  receive
more  frequent and extensive financial  disclosure concerning the foreign issuer
than the holder of an unsponsored ADR and will generally bear lower  transaction
charges. Each Fund may invest in both sponsored and unsponsored ADRs. The Select
International  Equity Fund  and the  Select Capital  Appreciation Fund  also may
utilize EDRs, which are designed for use in European securities markets and also
may invest in GDRs.
 
    Obligations in  which  the  Select  Income  Fund  may  invest  include  debt
obligations   of   supranational   entities.   Supranational   entities  include
international organizations designated or supported by governmental entities  to
promote   economic  reconstruction  or  development  and  international  banking
institutions and  related  government  agencies.  Obligations  of  supranational
entities may be supported by appropriated but unpaid commitments of their member
countries,  and there is no assurance  that these commitments will be undertaken
or met in the  future. The Fund may  not invest more than  25% of its assets  in
debt obligations of supranational entities.
 
RESTRICTED SECURITIES (APPLICABLE TO EACH FUND EXCEPT THE MONEY MARKET FUND)
 
    The  Funds also may purchase fixed-income securities that are not registered
under the Securities Act of 1933 ("1933 Act") ("restricted securities"), but can
be offered and sold to "qualified  institutional buyers" under Rule 144A of  the
1933  Act. However,  each Fund will  not invest more  than 15% of  its assets in
restricted securities (as  defined in  its investment  restrictions) unless  the
Funds'  Board  of Trustees  determines, based  upon a  continuing review  of the
trading markets  for  the specific  restricted  security, that  such  restricted
securities  are  liquid.  The  Board  of  Trustees  has  adopted  guidelines and
delegated to  the  Manager the  daily  function of  determining  and  monitoring
liquidity  of restricted securities. The  Board, however, will retain sufficient
oversight and be ultimately responsible for the determinations. Since it is  not
possible  to  predict  with assurance  exactly  how this  market  for restricted
securities sold  and  offered under  Rule  144A  will develop,  the  Board  will
carefully  monitor  the  Funds'  investments  in  securities,  focusing  on such
important factors, among  others, as  valuation, liquidity  and availability  of
information.  This investment practice  could have the  effect of increasing the
level of illiquidity  in the  Fund to  the extent  that qualified  institutional
buyers become for a time uninterested in purchasing these restricted securities.
As  a result, the  Funds might not be  able to sell  these securities when their
Sub-Adviser wishes to do so, or might have to sell them at less than fair value.
In addition, market quotations are  less readily available. Therefore,  judgment
may at times play a greater role in valuing these securities than in the case of
unrestricted securities.

<PAGE>
OPTIONS AND FUTURES TRANSACTIONS (APPLICABLE TO EACH FUND EXCEPT THE MONEY
MARKET FUND) AND
FORWARD CONTRACTS AND SWAPS (APPLICABLE TO THE SELECT CAPITAL APPRECIATION FUND)
 
    Through the writing and purchase of put and call on its option its portfolio
securities,  financial indices and foreign currencies  and the purchase and sale
of futures contracts and related  options with respect to securities,  financial
indices  and  (in the  case  of the  Select  Capital Appreciation  Fund) foreign
currencies in which it may invest, each Fund except the Money Market Fund may at
times seek to hedge against fluctuations in net asset value. Each Fund's ability
to engage in options and futures  strategies will depend on the availability  of
liquid  markets in such instruments.  It is impossible to  predict the amount of
trading interest  that  may  exist  in  various  types  of  options  or  futures
contracts.  Therefore, there  is no  assurance that  the Funds  will be  able to
utilize these instruments effectively for the purposes stated above.
 
    Additionally, the Select  Capital Appreciation  Fund may  invest in  forward
contracts and swaps which may expose the Fund to additional investment risks and
transaction costs.
 
    Risks  inherent in the use of  futures, options, forward contracts and swaps
("derivative instruments") include (1) the risk that interest rates,  securities
prices  and currency  markets will not  move in the  directions anticipated; (2)
imperfect correlation between the price of derivative instruments and  movements
in  the prices of the securities, interest rates or currencies being hedged; (3)
the fact that  skills needed to  use these strategies  are different from  those
needed  to select  portfolio securities;  (4) the  possible absence  of a liquid
secondary market for any particular instrument at any time; and (5) the possible
need to  defer  closing  out  certain hedged  positions  to  avoid  adverse  tax
consequences.
 
    The  Fund will purchase futures  and options only on  exchanges or boards of
trade when there appears to be an  active secondary market, but there can be  no
assurance that a liquid secondary market will exist for any futures or option at
any particular time.
 
    In  connection with transactions  in futures and  related options, the Funds
will be  required  to deposit  as  "initial margin"  an  amount of  cash  and/or
securities.  Thereafter, subsequent payments are made  to and from the broker to
reflect changes in the value of the futures contract.
 
    A more  detailed  explanation  of futures,  options,  and  other  derivative
instruments, and the risks associated with them, is included in the SAI.
 
INVESTMENT IN MONEY MARKET SECURITIES (APPLICABLE TO ALL FUNDS)
 
    Any  Fund may hold at  least a portion of its  assets in cash equivalents or
money market instruments. There is  always the risk that  the issuer of a  money
market instrument may be unable to make payment upon maturity.
 
    The  Money Market Fund may hold uninvested cash reserves pending investment,
during temporary defensive  periods or if,  in the opinion  of the  Sub-Adviser,
suitable  securities are not  available for investment.  Securities in which the
Money Market Fund may invest may not earn  as high a level of current income  as
long  term,  lower  quality  securities  which,  however,  generally  have  less
liquidity, greater market risk and more fluctuation in market value.
 
   
    Pursuant to  an  exemptive order  granted  by the  Securities  and  Exchange
Commission,  the Select  Capital Appreciation  Fund and  other funds  advised by
Janus Capital may transfer daily uninvested cash balances into one or more joint
trading accounts. Assets  in the joint  trading accounts are  invested in  money
market  instruments and the proceeds are allocated to the participating funds on
a pro rata basis.
    
 
HIGH YIELD SECURITIES (APPLICABLE TO THE SELECT CAPITAL APPRECIATION FUND,
SELECT GROWTH FUND AND SELECT GROWTH AND INCOME FUND)
 
    Corporate debt securities purchased by the Select Capital Appreciation,  the
Select  Growth Fund and Select Growth and Income  Fund will be rated at the time
of purchase B  or better by  Moody's or  S&P, or equivalently  rated by  another
NRSRO,  or unrated but believed  by the Sub-Adviser to  be of comparable quality
under guidelines  established for  the Funds.  The Select  Growth Fund  and  the
 
                                       24
<PAGE>
Select  Growth and Income Fund may invest more  than 15% of their assets and the
Select Capital Appreciation Fund may not invest  more than 35% of its assets  at
the  time of investment in securities rated below  Baa by Moody's or BBB by S&P,
or equivalently  rated  by  another  NRSRO,  or  unrated  but  believed  by  the
Sub-Adviser  to be of comparable  quality. Securities rated B  by Moody's or S&P
(or  equivalently  by  another  NRSRO)  are  below  investment  grade  and   are
considered, on balance, to be predominantly speculative with respect to capacity
to  pay interest and repay principal and will generally involve more credit risk
than securities in the higher rating categories.
 
    Periods of economic  uncertainty and changes  can be expected  to result  in
increased  volatility of market prices of lower-rated securities, commonly known
as "high yield" securities or  "junk bonds", and the  asset value of the  Select
Capital  Appreciation Fund, the Select Growth  Fund and Select Growth and Income
Fund. Many issuers  of high  yield corporate debt  securities are  substantially
leveraged,  which may  impair their  ability to  meet debt  service obligations.
Also, during  an economic  downturn  or substantial  period of  rising  interest
rates, highly leveraged issuers may experience financial stress.
 
    The  lack of a liquid secondary market in certain lower-rated securities may
have an  adverse impact  on their  market price  and the  ability of  a Fund  to
dispose  of particular issues when  necessary to meet its  liquidity needs or in
response  to  a  specific  economic  event  such  as  a  deterioration  in   the
credit-worthiness of the issuer. In addition, a less liquid market may interfere
with  the  ability of  a Fund  to  accurately value  high yield  securities and,
consequently, value  the  Fund's  assets.  Furthermore,  adverse  publicity  and
investor  perceptions  may  decrease  the  value  and  liquidity  of  high yield
securities. It is  reasonable to expect  any recession to  severely disrupt  the
market  for high  yield fixed-income securities,  have an adverse  impact on the
value of such securities and adversely affect the ability of the issuers of such
securities to repay  principal and  pay interest  thereon. The  market price  of
lower-rated  securities are  generally less  sensitive to  interest rate changes
than higher-rated  investments,  but  more  sensitive  to  adverse  economic  or
political changes, or individual developments specific to the issuer. Periods of
economic  or  political  uncertainty  and  change  can  be  expected  to  result
involatility of price of these securities.
 
    The Funds also may invest in unrated debt securities of foreign and domestic
issuers. Unrated  debt,  while  not  necessarily of  lower  quality  than  rated
securities,  may  not  have  as  broad  a  market.  Sovereign  debt  of  foreign
governments is generally  rated by country.  Because these ratings  do not  take
into  account individual factors relevant  to each issue and  may not be updated
regularly, the Sub-Adviser may  treat such securities  as unrated debt.  Unrated
debt  securities and securities with different ratings from more than one agency
will be included in the 15% and 35% limits of the Funds as stated above,  unless
such Fund's Sub-Adviser deems such securities to be the equivalent of investment
grade securities. See the Appendix for a description of the bond ratings.
 
ASSET-BACKED SECURITIES AND MORTGAGE-BACKED SECURITIES (APPLICABLE TO SELECT
INCOME FUND)
 
    The   Fund  may   purchase  asset-backed   securities,  which   represent  a
participation in,  or are  secured by  and payable  from, a  stream of  payments
generated  by  particular assets,  frequently a  pool of  assets similar  to one
another. Assets  generating  such payments  include  instruments such  as  motor
vehicle  installment  purchase  obligations, credit  card  receivables  and home
equity loans. Payment of  principal and interest may  be guaranteed for  certain
amounts and time periods by a letter of credit issued by a financial institution
unaffiliated  with  the  issuer of  the  securities.  The estimated  life  of an
asset-backed security varies  with the prepayment  experience of the  underlying
debt  instruments.  The rate  of such  prepayments,  and hence  the life  of the
asset-backed security, will  be primarily  a function of  current market  rates,
although  other economic and demographic factors will be involved. Under certain
interest rates and prepayment rate scenarios, the Fund may fail to recoup  fully
their  investment in asset-baked securities. The  Fund will not invest more than
10% of its total assets in asset-backed securities.
 
    The Fund  also  may invest  in  mortgage-backed securities  which  are  debt
obligations  secured by real  estate loans and  pools of loans  on single family
homes, multi-family homes, mobile homes, and in
 
                                       25
<PAGE>
some cases, commercial properties. The Fund may acquire securities  representing
an  interest in a pool of mortgage loans that are issued or guaranteed by a U.S.
government agency such as the Government National Mortgage Association  ("Ginnie
Mae"),  the Federal National Mortgage Association ("Fannie Mae") and the Federal
Home Loan Mortgage Corporation ("Freddie Mac").
 
    Mortgage-backed securities  are in  most cases  "pass-through"  instruments,
through which the holder receives a share of all interest and principal payments
from   the  mortgages   underlying  the  certificate.   Because  the  prepayment
characteristics of the underlying mortgages vary, it is not possible to  predict
accurately  the  average  life  or  realized yields  of  a  particular  issue of
pass-through  certificates.  During   periods  of   declining  interest   rates,
prepayment of mortgages underlying mortgage-backed securities can be expected to
accelerate.  When the mortgage  obligations are prepaid,  the Fund reinvests the
prepaid amounts  in  securities, the  yield  of which  reflects  interest  rates
prevailing  at  the  time.  Moreover,  prepayment  of  mortgages  that  underlie
securities purchased at a premium could result in losses.
 
    The Fund  also  may invest  in  multiple  class securities  issued  by  U.S.
government  agencies and instrumentalities  such as Fannie  Mae, Freddie Mac and
Ginnie Mae, including  guaranteed collateralized  mortgage obligations  ("CMOs")
and   Real  Estate   Mortgage  Investment  Conduit   ("REMIC")  pass-through  or
participation  certificates,  when   consistent  with   the  Fund's   investment
objective,  policies and  limitations. A  CMO is  a type  of bond  secured by an
underlying pool  of mortgages  or mortgage  pass-through certificates  that  are
structured  to direct  payment on underlying  collateral to  different series or
classes of  obligations.  A  REMIC is  a  CMO  that qualifies  for  special  tax
treatment  under  the Internal  Revenue Code  and  invests in  certain mortgages
principally  secured  by  interests  in   real  property  and  other   permitted
investments.
 
    CMOs  and guaranteed REMIC  pass-through certificates ("REMIC Certificates")
issued by  Fannie  Mae,  Freddie  Mac  and Ginnie  Mae  are  types  of  multiple
pass-through  securities. Investors may purchase beneficial interests in REMICs,
which are known as  "regular" interests or "residual"  interests. The Fund  does
not  currently  intend  to  purchase residual  interests  in  REMICs.  The REMIC
Certificates  represent  beneficial  ownership  interests  in  a  REMIC   trust,
generally  consisting of mortgage loans or Fannie Mae, Freddie Mac or Ginnie Mae
guaranteed mortgage pass-through  certificates. The obligations  of Fannie  Mae,
Freddie  Mac  or  Ginnie  Mae  under  their  respective  guaranty  of  the REMIC
Certificates are obligations solely  of Fannie Mae, Freddie  Mac or Ginnie  Mae,
respectively.
 
    Fannie  Mae  REMIC  Certificates  are issued  and  guaranteed  as  to timely
distribution of principal and  interest by Fannie Mae.  In addition, Fannie  Mae
will  be obligated to  distribute the principal  balance of each  class of REMIC
Certificates in full, whether or not sufficient fund are otherwise available.
 
    For Freddie  Mac  REMIC  Certificates, Freddie  Mac  guarantees  the  timely
payment  of interest, and  also guarantees the payment  of principal as payments
are required to be  made on the  underlying mortgage participation  certificates
("PCs").  PCs represent undivided interest in specified residential mortgages or
participation therein purchases  by Freddie Mac  and placed in  a PC pool.  With
respect  to principal payments on PCs, Freddie Mac generally guarantees ultimate
collection of all  principal of  the related  mortgage loans  without offset  or
deduction.  Freddie Mac also  guarantees timely payment  of principal on certain
PCs referred to as "Gold PCs."
 
    Ginnie Mae  REMIC Certificates  guarantee  the full  and timely  payment  of
interest and principal on each class of securities (in accordance with the terms
of  those classes,  as specified in  the related  offering circular supplement).
This Ginnie Mae guarantee is backed by  the full faith and credit of the  United
States of America.
 
    REMIC  Certificates issued  by Fannie  Mae, Freddie  Mac and  Ginnie Mae are
treated as U.S. government securities for purposes of investment policies. There
can be no assurance that the  United States government will continue to  provide
financial support to Fannie Mae, Freddie Mac or Ginnie Mae in the future.

<PAGE>
STRIPPED MORTGAGE-BACKED SECURITIES (APPLICABLE TO THE SELECT INCOME FUND)
 
    The  Fund may invest  in Stripped Mortgage-Backed  Securities ("SMBS"). SMBS
are derivative multiclass mortgage securities. SMBS may be issued by agencies or
instrumentalities of  the  U.S. Government  or  by private  originators  of,  or
investors  in, mortgage loans, including savings and loan associations, mortgage
banks, commercial banks, investment  banks and special  purpose entitles of  the
foregoing.
 
   
    SMBS  are  usually  structured  with  two  classes  that  receive  different
proportions of the interest  and principal distributions on  a pool of  mortgage
assets.  One type of SMBS 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 some cases,
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  a IO class is extremely sensitive to  the
rate  of  principal payments  (including  prepayment on  the  related underlying
mortgage assets), and  a rapid rate  of principal payments  may have a  material
adverse  effect on a portfolio  yield to maturity from  these securities. If the
underlying mortgage assets  experience greater than  anticipated prepayments  of
principal,  the Fund may fail to fully  recoup their initial investment in these
securities even if  the security  is in one  of the  highest rating  categories.
Certain  SMBS may be deemed "illiquid" and  subject to the Fund's limitations on
investment in illiquid securities. The market value of the PO class generally is
unusually volatile in  response to changes  in interest rates.  The yields on  a
class of SMBS that receives all or most of the interest from mortgage assets are
generally   higher  than  prevailing  market  yields  in  other  mortgage-backed
securities because their  cash flow patterns  are more volatile  and there is  a
grater  risk that the  initial investment will  not be fully  recouped. The Sub-
Adviser will seek to manage these risks (and potential benefits) by investing in
a variety of such securities and by using certain hedging techniques.
    
 
HEDGING TECHNIQUES AND INVESTMENT PRACTICES (APPLICABLE TO THE SELECT
INTERNATIONAL EQUITY FUND AND SELECT CAPITAL APPRECIATION FUND)
 
    The Select International  Equity Fund  and the  Select Capital  Appreciation
Fund  may employ certain strategies in order  to manage exchange rate risks. For
example, the Funds may hedge some or  all of their investments denominated in  a
foreign  currency against a decline in the value of that currency. The Funds may
enter into  contracts  to sell  that  foreign  currency for  U.S.  dollars  (not
exceeding  the value  of a  Fund's assets  denominated in  that currency)  or by
participating in  options or  futures contracts  with respect  to such  currency
("position hedge"). The Funds also could hedge that position by selling a second
currency,  which  is expected  to  perform similarly  to  the currency  in which
portfolio investments  are denominated  for U.S.  dollars ("proxy  hedge").  The
Funds  also may enter into a forward contract  to sell the currency in which the
security is denominated for a second currency that is expected to perform better
relative to the U.S. dollar if their Sub-Adviser believes there is a  reasonable
degree  of correlation between movements  in the two currencies ("cross-hedge").
As an operational  policy, the  Funds will  not commit  more than  10% of  their
assets  to  the  consummation of  cross-hedge  contracts and  will  either cover
currency hedging transactions  with liquid portfolio  securities denominated  in
the  applicable currency or segregate high-grade, liquid assets in the amount of
such commitments. In addition, when the Funds anticipate repurchasing securities
denominated in  a  particular currency,  the  Funds  may enter  into  a  forward
contract  to  purchase  such currency  in  exchange  for the  dollar  or another
currency ("anticipatory hedge").
 
    These strategies minimize  the effect  of currency appreciation  as well  as
deprecation, but do not protect against a decline in the underlying value of the
hedged  security.  In  addition, such  strategies  may reduce  or  eliminate the
opportunity to profit from increases in  the value of the original currency  and
may adversely impact the Funds' performance if their Sub-Adviser's projection of
future exchange rates is inaccurate.

COMMERCIAL PAPER RATINGS
 
    MOODY'S  EMPLOYS THREE DESIGNATIONS,  ALL JUDGED TO  BE INVESTMENT GRADE, TO
INDICATE THE  RELATIVE REPAYMENT  CAPACITY  OF RATED  ISSUERS. THE  TWO  HIGHEST
DESIGNATIONS ARE AS FOLLOWS:
 
        Issuers  rated  Prime-1  (or  related  supporting  institutions)  have a
    superior  capacity  for  repayment  of  short-term  promissory  obligations.
    Prime-1  repayment  capacity will  normally  be evidenced  by  the following
    characteristics:
 
       -- Leading market positions in well-established industries.
 
       -- High rates of return on funds employed.
 
       -- Conservative capitalization structures with moderate reliance on  debt
          and ample asset protection.
 
       -- Broad margins in earnings coverage of fixed financial charges and high
          internal cash generation.
 
       -- Well-established  access to a  range of financial  markets and assured
          sources of alternate liquidity.
 
        Issuers rated Prime-2 (or related supporting institutions) have a strong
    capacity for repayment of  short-term promissory obligations. This  normally
    will  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  alternate
    liquidity is maintained.
 
   
    S&P  COMMERCIAL PAPER  RATINGS ARE  GRADED INTO  SEVERAL CATEGORIES, RANGING
FROM "A-1" FOR THE HIGHEST  QUALITY OBLIGATIONS TO "D"  FOR THE LOWEST. THE  TWO
HIGHEST RATING CATEGORIES ARE DESCRIBED AS FOLLOWS:
    
 
   
        A-1  --  This  highest  category indicates  that  the  degree  of safety
    regarding timely  payment  is strong.  Those  issues determined  to  possess
    extremely  strong safety  characteristics are denoted  with a  plus (+) sign
    designation.
    
 
   
        A-2 -- Capacity for  timely payment on issues  with this designation  is
    satisfactory.  However, the relative degree of safety  is not as high as for
    issues designated A-1.
    
 
MUNICIPAL OBLIGATIONS
 
    Moody's ratings for  state and  municipal and  other short-term  obligations
will  be designated  Moody's Investment  Grade ("MIG").  This distinction  is in
recognition of  the differences  between short-term  credit risk  and  long-term
risk.  Factors  affecting  the  liquidity  of  the  borrower  are  uppermost  in
importance in  the short-term  borrowing,  while various  factors of  the  first
importance in long-term borrowing risk are of lesser importance in the long run.
Symbols used will be as follows:
 
   
        MIG-1  -- This designation denotes best quality. There is present strong
    protection  by  established  cash  flows,  superior  liquidity  support   or
    demonstrated broad-based access to the market for refinancing.
    
 
   
        MIG-2  -- This designation  denotes high quality.  Margins of protection
    are ample although not so large as in the preceding group.
    
 
    A short-term  rating  may also  be  assigned on  an  issue having  a  demand
feature. Such ratings will be designated as VMIG to reflect such characteristics
as  payment upon  periodic demand rather  than fixed maturity  dates and payment
relying  on  external  liquidity.   Additionally,  investors  should  be   alert
 
                                       28
<PAGE>
   
to  the fact that the source of payment may be limited to the external liquidity
with no or limited legal recourse to the issuer in the event that demand is  not
met.  VMIG-1 and VMIG-2 ratings  carry the same definitions  as MIG-1 and MIG-2,
respectively.
    
 
DESCRIPTION OF MOODY'S BOND RATINGS
 
   
    AAA -- Bonds that are rated Aaa are  judged to be of the best quality.  They
carry  the smallest degree of  investment risk and are  generally referred to as
"gilt edge". Interest payments are protected  by a large or by an  exceptionally
stable margin and principal is secure. While the various protective elements are
likely  to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.
    
 
   
    AA -- Bonds  that are  rated Aa  are judged  to be  of high  quality by  all
standards.  Together with the Aaa group,  they comprise what are generally known
as high-grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be  of greater  amplitude or there  may be  other elements  present
which make the long-term risks appear somewhat larger than in Aaa securities.
    
 
   
    A -- Bonds that are rated A possess many favorable investment attributes and
are  to be considered as upper medium grade obligations. Factors giving security
to principal and interest are considered  adequate, but elements may be  present
that suggest a susceptibility to impairment some time in the future.
    
 
   
    BAA  -- Bonds that are rated Baa are considered as medium grade obligations,
i.e., they are neither  highly protected nor  poorly secured. Interest  payments
and  principal security appear  adequate for the  present but certain protective
elements may be lacking or may  be characteristically unreliable over any  great
length  of time. Such  bonds lack outstanding  investment characteristics and in
fact have speculative characteristics as well.
    
 
   
    BA -- Bonds that are rated Ba are judged to have speculative elements; their
future cannot be considered  as well assured. Often  the protection of  interest
and  principal payments  may be very  moderate and thereby  not well safeguarded
during both  good  and  bad  times over  the  future.  Uncertainty  of  position
characterizes bonds in this class.
    
 
   
    B  -- Bonds that are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or maintenance of other
terms of the contract over any long period of time may be small.
    
 
   
    Those bonds within the Aa, A, Baa, Ba and B categories that Moody's believes
possess the strongest credit attributes  within those categories are  designated
by the symbols Aa1, A1, Baa1, Ba1 and B1.
    
 
   
DESCRIPTION OF S&P'S DEBT RATINGS
    
 
   
    AAA  -- Debt rated AAA  has the highest rating  assigned by S&P. Capacity to
pay interest and repay principal is extremely strong.
    
 
   
    AA -- Debt rated  AA has a  very strong capacity to  pay interest and  repay
principal and differs from AAA issues only in a 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.
    
 
                                       29
<PAGE>
   
    BB, B, CCC, CC,  C -- Debt  rated BB, B,  CCC, CC, C  is regarded as  having
predominantly  speculative  characteristics  with  respect  to  capacity  to pay
interest and repay principal. BB indicates the least degree of speculation and C
the highest.  While such  debt  will likely  have  some quality  and  protective
characteristics,  these are outweighed by large uncertainties or major exposures
to adverse conditions.
    
 
    PLUS (+) OR (-):  The ratings from AA to CCC may be modified by the addition
of a plus or minus sign to show relative standing within the major categories.

                           HOW ARE THE FUNDS MANAGED?
 
   
    The  overall responsibility for the supervision  of the affairs of the Trust
vests in the  Board of  Trustees of  the Trust who  meet on  a quarterly  basis.
Allmerica Investment Management Company, Inc. (the "Manager") is responsible for
the  management  of  the Trust's  day-to-day  business affairs  and  has general
responsibility for the management of the investments of the Funds. The  Manager,
at  its  expense,  has  contracted  with  certain  Sub-Advisers  to  manage  the
investments of the Funds, subject to the requirements of the Investment  Company
Act of 1940 (the "1940 Act").
    
 
   
    The  Manager  is  a  wholly-owned  subsidiary  of  First  Allmerica,  a life
insurance company, which was  organized in Massachusetts  in 1844. The  Manager,
organized  August 19, 1985,  also serves as  manager of the  Allmerica Funds, an
open-end investment company. The Manager and First Allmerica are located at  440
Lincoln Street, Worcester, Massachusetts 01653.
    
 
   
    The  Manager has entered  into Sub-Adviser Agreements  for the management of
the investments of each of the  Funds. The Sub-Advisers, who have been  selected
on  the  basis of  various factors  including management  experience, investment
techniques and staffing, are each authorized to engage in portfolio transactions
on  behalf  of  the  applicable  Funds  subject  to  such  general  or  specific
instructions  as may be given by the Trustees and/or the Manager. The terms of a
Sub-Adviser Agreement  cannot be  changed  without the  approval of  a  majority
interest  of the Shareholders  of the affected Fund.  The Sub-Advisers have been
selected by the Manager  and the Trustees in  consultation with Rogers, Casey  &
Associates  ("Rogers, Casey"),  a leading pension  consulting firm.  The cost of
such consultation is borne by the Manager.
    
 
    Rogers, Casey  provides consulting  services to  pension plans  representing
over  $150 billion in total assets and, in its consulting capacity, monitors the
investment performance  of over  1,000 investment  advisers. From  time to  time
specific  clients of Rogers, Casey  and the Sub-Advisers will  be named in sales
materials.  At  times,  Rogers,  Casey  assists  in  the  development  of  asset
allocation  strategies which may be used  by shareholders in the diversification
of their portfolio across different asset classes.
 
   
    Ongoing performance of the independent Sub-Adviser is reviewed and evaluated
by a committee whose members may include senior officers of First Allmerica, its
affiliates or the Manager and an independent consultant. Combined, the committee
has over 150 years of investment experience. Historical performance data for the
Funds is set forth in the "Financial  Highlights" table starting on page 3.  The
Manager  is solely responsible for the payment  of all fees to the Sub-Advisers.
The SubAdvisers for each of the Funds are as follows:

    The  Manager also has entered into an Administrative Services Agreement with
First  Data  Investor  Services  Group,  Inc.  ("First  Data"),  a  wholly-owned
subsidiary of First Data Corporation, whereby First Data performs administrative
services  for each of the Funds and is entitled to receive an administrative fee
and certain out-of-pocket expenses.  The Manager is  solely responsible for  the
payment of the administrative fee to First Data.

<PAGE>
                WHAT ARE THE INVESTMENT OBJECTIVES AND POLICIES?
 
    Each  Fund has a separate investment objective and policies designed to meet
different investment  and  financial needs,  as  described below.  There  is  no
assurance that a Fund will achieve its investment objective.
 
   
    The  Select International Equity  Fund and Select  Agressive Growth Fund may
each invest up to  15% of its  assets in securities  which are illiquid  because
they are subject to restriction on resale or for which market quotations are not
readily   available.  The  Select  International  Equity  Fund  may  invest  any
percentage of its  assets in  foreign securities and  each of  the other  Funds,
except  the Government Bond and Money Market Funds,  may invest up to 25% of its
assets  in  foreign  securities  (not  including  its  investments  in  American
Depositary  Receipts ("ADRs")). The Investment Grade  Income Fund may not invest
in foreign securities other than obligations issued by the Government of  Canada
and  political  subdivisions  thereof. See  "Certain  Investment  Strategies and
Policies."
    
 
    A Fund's investment objective is fundamental and may not be changed  without
shareholder  approval. Unless otherwise indicated,  a Fund's investment policies
are not fundamental and may be changed without shareholder approval.
 
   
SELECT INTERNATIONAL EQUITY FUND
    
 
   
    INVESTMENT OBJECTIVE:   The Select International  Equity Fund seeks  maximum
long-term  total return (capital appreciation and income) primarily by investing
in common stocks of established non-U.S. companies.
    
 
   
    SUB-ADVISER:   Bank  of Ireland  Asset  Management (U.S.)  Limited  ("BIAM")
serves  as  Sub-Adviser for  the Select  International Equity  Fund. BIAM  is an
indirect wholly-owned subsidiary of Bank of Ireland. Its main offices are at  26
Fitzwilliam  Place, Dublin  2, Ireland.  Its U.S.  offices are  at Two Greenwich
Plaza, Greenwich,  CT  06830. Bank  of  Ireland provides  investment  management
services  through a network of sister companies, including BIAM which represents
North American  clients.  As of  December  31,  1995, Bank  of  Ireland  managed
approximately  $15  billion  in  global securities  for  Irish,  United Kingdom,
European and U.S. clients.
    
 
   
    INVESTMENT POLICIES:   To achieve  its objective,  the Select  International
Equity  Fund  will invest  primarily in  common  stocks of  established non-U.S.
companies. Under normal  market conditions,  at least  65% of  the Fund's  total
assets  will be invested  in the securities  of companies domiciled  in at least
five foreign  countries, not  including the  United States.  The Fund  may  also
acquire  fixed-income debt securities. It will do so, at the discretion of BIAM,
primarily for defensive purposes.
    
 
   
    The  Fund's  investments  may  include  ADRs  which  may  be  sponsored   or
unsponsored  by  the  underlying  issuer. The  Fund  may  also  utilize European
Depositary Receipts  ("EDRs"),  which  are  similar to  ADRs,  in  bearer  form,
designed  for  use  in  the European  securities  market  and  Global Depositary
Receipts ("GDRs"). Investments in foreign securities carry additional risks  not
present  in domestic securities. See "Certain Investment Strategies and Policies
- -- Foreign  Securities." The  Fund  may, for  hedging  purposes, engage  in  the
options  and futures  strategies described under  "Certain Investment Strategies
and  Policies."  Certain  state  insurance  regulations  may  impose  additional
restrictions on the Fund's holdings of foreign securities.
    
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the Fund was 24%. The portfolio turnover rate for the Fund may vary greatly from
year to year.
    
 
   
SELECT AGGRESSIVE GROWTH FUND
    
 
   
    INVESTMENT OBJECTIVE:  The Select Aggressive Growth Fund seeks above-average
capital  appreciation by investing primarily in common stocks of companies which
are believed to have significant potential for capital appreciation.
    
 
   
    SUB-ADVISER:   Nicholas-Applegate  Capital  Management  ("NACM")  serves  as
Sub-Adviser  to the Select Aggressive Growth Fund. NACM is an investment manager
supervising accounts with assets
    
 
                                       9
<PAGE>
   
totaling approximately $29  billion in  total assets  as of  December 31,  1995.
NACM's  clients  are primarily  major corporate  employee benefit  funds, public
employee retirement plans, foundations and endowment funds, investment companies
and individuals. Founded in  1984, NACM is located  at 600 West Broadway,  Suite
2900, San Diego, California 92101.
    
 
   
    INVESTMENT POLICIES:  Under normal circumstances, at least 65% of the assets
of  the Select  Aggressive Growth  Fund will  be invested  in equity securities,
consisting  of  common  stocks,   securities  convertible  into  common   stocks
(including  bonds, notes and  preferred stocks) and  warrants. The Fund's assets
may also be  invested in other  debt securities and  preferred stocks when  such
securities  are believed appropriate in light of the Fund's investment objective
and market conditions.
    
 
   
    The selection of securities is made  solely on the basis of their  potential
for  capital appreciation. Dividend and interest  income, if any, from portfolio
securities is incidental to the  Fund's investment objective. While  investments
may  be made in  well-known and established companies,  a significant portion of
the Fund's investments is expected to  be in securities of newer and  relatively
unseasoned companies or companies which represent new or changing industries.
    
 
   
    At  any given point  a substantial portion of  the Fund's equity investments
may be in  securities which are  not listed for  trading on national  securities
exchanges  and, although  publicly traded,  may be  less liquid  than securities
issued by larger,  more seasoned  companies which trade  on national  securities
exchanges.  Up to  15% of  the Fund's  assets may  be invested  in restricted or
illiquid securities.
    
 
   
    Securities of newer companies may be closely held with only a small  portion
of their outstanding securities owned by the general public. Newer companies may
have  relatively small revenue, lack depth of  management and have a small share
of the market for their products or services; thus, they may be more  vulnerable
to  changes  in  economic  conditions,  market  fluctuations  and  other factors
affecting the  profitability or  marketability of  companies. Due  to these  and
other  factors, the  price movement of  the securities  held by the  Fund can be
expected to be more volatile than is the case for the market as a whole, and the
net  asset  value  of  a  share   of  the  Fund  may  fluctuate   significantly.
Consequently,  the Fund should not be  considered suitable for investors who are
unable or unwilling to assume the risk of loss inherent in an aggressive  growth
portfolio,  nor  should  investment in  the  Fund  be considered  a  balanced or
complete investment program.
    
 
   
    When NACM determines  that market conditions  warrant a temporary  defensive
position,  the Fund  may invest  without limitation  in high-grade, fixed-income
securities,  U.S.  Government  securities,  or  hold  assets  in  cash  or  cash
equivalents.  The  Fund may,  for hedging  purposes, engage  in the  options and
futures strategies described under "Certain Investment Strategies and Policies".
    
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the  Fund  was  104%.  The  portfolio   turnover  rate  was  104%  because   the
Sub-Adviser's  investment approach typically  results in above-average portfolio
turnover as securities are  sold when the Sub-Adviser  believes the reasons  for
their  initial purchase are no longer valid or when it believes that the sale of
a security owned by the  Fund and the purchase  of another security can  enhance
return. A security may be sold to avoid a prospective decline in market value or
purchased  in anticipation  of a  market rise.  Although it  is not  possible to
predict future  portfolio turnover  rates accurately,  and such  rates may  vary
greatly  from year to year, NACM  anticipates that the annual portfolio turnover
generally will  not exceed  100%. A  high portfolio  turnover rate  will  likely
result in greater brokerage costs to the Fund.
    
 
GROWTH FUND
 
    INVESTMENT  OBJECTIVE:  The Growth Fund seeks to achieve long-term growth of
capital  through  investments   primarily  in  common   stocks  and   securities
convertible  into  common  stocks  that are  believed  to  represent significant
underlying value in relation  to current market  prices. Realization of  current
income, if any, is incidental to this objective.
 
   
    SUB-ADVISER:   Miller Anderson & Sherrerd, LLP ("MAS") serves as Sub-Adviser
for the  Growth  Fund.  MAS, which  is  wholly  owned by  Morgan  Stanley  Asset
Management Holdings, Inc., is located at
    
 
                                       10
<PAGE>
   
One Tower Bridge, West Conshohocken, Pennsylvania 19428. MAS provides investment
counseling services to employee benefit plans, endowment funds, foundations, and
other  institutional  investors,  and  had  over  $35  billion  in  assets under
management as  of December  31, 1995.  MAS is  the adviser  of the  MAS Fund,  a
registered  investment company offering investment alternatives to institutional
clients, with  a minimum  initial investment  of $1  million. MAS  also  manages
certain assets for First Allmerica and its affiliates.
    
 
   
    INVESTMENT  POLICIES:  The Growth Fund is  not limited to investments in any
particular type of company and may invest  in any company which, in the  opinion
of  management, is likely  to further its investment  objective. The Growth Fund
will  pursue  its  investment  objective  by  maintaining  a  flexible  position
regarding the type of companies, as well as the types of securities, in which it
will  invest. Investments  may include,  but are  not limited  to, developing or
well-established companies, whether small or large. It is anticipated that there
will be a mix of assets in the Growth Fund. For example, portions of the  Growth
Fund may be invested in equity securities of good quality or in well-established
companies  considered  to  represent  good  value,  based  on  factors including
historical  investment   standards  (such   as  price/book   value  ratios   and
price/earnings  ratios) or in smaller emerging growth companies which are in the
development stage  and are  expected to  achieve above-average  earnings  growth
because  of  special  factors (such  as  changes  in the  economy,  the relative
attractiveness of  the  various  securities  markets,  or  changes  in  consumer
demand).
    
 
   
    The Growth Fund proposes to keep its assets fully invested, but may maintain
reasonable  amounts in cash or in high-grade, short-term debt securities to meet
current expenses  and  anticipated  redemptions, and  during  temporary  periods
pending  investment  in  accordance  with its  policies.  The  term "high-grade,
short-term debt  securities"  means Items  (a),  (b)  and (c)  of  Money  Market
Instruments under the Investment Grade Income Fund's Investment Policies.
    
 
    The  Growth Fund  normally will  invest substantially  all of  its assets in
equity-type securities, including common stocks, warrants (which are options  to
purchase  common stock at  specified prices during a  specified time period with
the investment risk that the market value of the underlying common stock may not
be high enough  in relation to  the warrant exercise  price to justify  purchase
pursuant  to  the terms  of the  warrant)  and those  preferred stocks  and debt
securities convertible into or  carrying rights to purchase  common stock or  to
participate  in earnings, and real estate  securities to the extent permitted by
paragraph four under Investment Restrictions  in the SAI. In periods  considered
by  management to warrant a more defensive position, the Growth Fund may place a
larger proportion of  its portfolio  in high-grade preferred  stocks, bonds,  or
other  fixed income securities, including U.S. Government securities, whether or
not convertible into stock or with rights attached, or retain cash. The Fund may
engage in the options and futures strategies described under "Certain Investment
Strategies and Policies."
 
    The Growth  Fund may  invest in  both listed  and unlisted  securities.  The
Growth  Fund may  also invest  in foreign, as  well as  domestic securities. The
Growth Fund  will not  concentrate  its foreign  investments in  any  particular
foreign  country,  or  limit its  investments  to issuers  listed  on particular
exchanges or traded in particular  money market centers. Investments in  foreign
securities  carry  additional  risks  not present  in  domestic  securities. See
"Certain Investment  Strategies and  Policies."  The Sub-Adviser  will  consider
these  and other factors before investing and  will not cause the Growth Fund to
invest in foreign securities unless, in its opinion, such investments will  meet
the standards and objectives of the Growth Fund.
 
    The  investment  objective  and  policies in  the  first,  third  and fourth
paragraphs of this section  on the Growth  Fund are fundamental  and may not  be
changed without shareholder approval.
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the Fund was 64%. The portfolio turnover rate for the Fund may vary greatly from
year to year.

EQUITY INDEX FUND
 
    INVESTMENT  OBJECTIVE:   The Equity Index  Fund seeks  to achieve investment
results that  correspond to  the  aggregate price  and  yield performance  of  a
representative selection of common stocks that are publicly traded in the United
States.
 
   
    SUB-ADVISER:  Allmerica Asset Management, Inc. ("AAM") serves as Sub-Adviser
to  the Equity Index  Fund as well  as Investment Grade  Income Fund, Government
Bond Fund  and  Money Market  Fund.  AAM,  a wholly-owned  subsidiary  of  First
Allmerica,  was  incorporated in  1993  and is  located  at 440  Lincoln Street,
Worcester, Massachusetts 01653. As of  December 31, 1995, AAM had  approximately
$10.85  billion in assets under management.  AAM serves as investment adviser to
First Allmerica's  General  Account and  to  a number  of  affiliated  insurance
companies  and other affiliated accounts and  as Adviser to Allmerica Securities
Trust, a diversified, closed-end investment management company.
    
 
   
    INVESTMENT POLICIES:    The Equity  Index  Fund  will seek  to  achieve  its
objective  by attempting to replicate the  aggregate price and yield performance
of the Standard &  Poor's Composite Index  of 500 Stocks  ("S&P 500"). The  Fund
uses  the S&P  500 as  the performance  standard because  it represents  over 70
percent of the total market value of all publicly traded common stocks in the U.
S., is  well-known to  investors, and,  in the  opinion of  the Sub-Adviser,  is
representative  of the performance of common  stocks publicly traded in the U.S.
Many, but not all, of the stocks in the S&P 500 are issued by companies that are
among the  500  largest as  measured  by the  aggregate  market value  of  their
outstanding  stock  (market  price  per share  multiplied  by  number  of shares
outstanding). Inclusion of a stock  in the S&P 500 does  not imply that S&P  has
endorsed  it as an investment. With respect to investing in common stocks, there
can be no assurance of capital appreciation  and there is a substantial risk  of
market decline.
    
 
    The  method used  to select investments  for the Fund  involves investing in
common stocks in  approximately the order  of their weightings  in the S&P  500,
beginning  with  those  having the  highest  weightings. In  addition,  the Fund
purchases stocks with smaller weightings in order to represent other sectors  of
the S&P 500 for diversification purposes.
 
    The Equity Index Fund will invest only in those stocks, and in such amounts,
as  its Sub-Adviser determines  to be necessary  or appropriate for  the Fund to
approximate the performance  of the S&P  500. Under normal  circumstances it  is
expected  that the Fund will hold between  300 and 475 different stocks included
in the S&P  500. The Fund  may compensate for  the omission of  a stock that  is
included  in  the S&P  500,  or for  purchasing stocks  in  other than  the same
proportions that they are represented in the S&P 500, by purchasing stocks  that
are  believed to  have characteristics that  correspond to those  of the omitted
stocks. The  Fund also  may invest  in short-term  debt securities  to  maintain
liquidity  or pending  investment in  stocks. The  Fund also  may engage  in the
options and futures  strategies described under  "Certain Investment  Strategies
and Policies."
 
   
    Because  of its policy of tracking the S&P 500, the Equity Index Fund is not
managed according to traditional methods of active investment management,  which
involve  the buying and selling of  securities based upon investment analysis of
economic, financial  and market  factors.  Consequently, the  projected  adverse
financial  performance of a company would not normally result in the sale of the
company's stock and projected superior financial performance by a company  would
not  normally lead to an  increase in the holdings of  the company. From time to
time the  Sub-Adviser may  make adjustments  in the  portfolio because  of  cash
flows,  mergers, changes in the composition of  the S&P 500 and similar reasons.
Portfolio turnover is expected to be lower than that of most funds investing  in
common  stock.  For  the fiscal  year  ended  December 31,  1995,  the portfolio
turnover rate for the Fund was 8%.
    
 
    The Equity Index Fund's ability to duplicate the performance of the S&P  500
will be influenced by the size and timing of cash flows into or out of the Fund,
the  liquidity  of  the securities  included  in  the S&P  500,  transaction and
operating expenses, and other factors. In addition, the Fund will incur expenses
(including advisory  and administrative  fees)  that are  not reflected  in  the
performance
 
                                       12

results  of the S&P  500. These factors,  among others, may  result in "tracking
error," which is a measure of the degree to which the Fund's results differ from
the results of the S&P 500. Due to  such factors, the return of the Fund may  be
lower than the return of the S&P 500.
 
   
    Tracking  error is measured  by the difference between  total return for the
S&P 500 with dividends reinvested and  total return for the Fund with  dividends
reinvested  after  deductions of  fees  and expenses.  For  the 12  months ended
December 31, 1995, the  S&P 500 gained  37.53% versus a gain  of 36.18% for  the
Equity  Index  Fund  producing a  tracking  error  of 1.35%.  Tracking  error is
monitored by the Sub-Adviser on a daily basis. All tracking error deviations are
reviewed to determine the effectiveness  of investment policies and  techniques.
If  the tracking error deviation exceeds industry standards for the Fund's asset
size, the Sub-Adviser will bring the deviation to the attention of the Trustees.
    
 
    While the Board of Trustees of the Trust has initially selected the S&P  500
as  the index the Fund will attempt to replicate, the Trustees reserve the right
to select another index at any time without seeking shareholder approval if they
believe that the S&P 500 no longer represents a broad spectrum of common  stocks
that are publicly traded in the United States or if there are legal, economic or
other  factors limiting the use of any  particular index. If the Trustees change
the index which the  Equity Index Fund attempts  to replicate, the Equity  Index
Fund  may incur  significant transaction  costs in  switching from  one index to
another.

INVESTMENT GRADE INCOME FUND
 
    INVESTMENT  OBJECTIVE:   The Investment  Grade Income  Fund seeks  as high a
level of total return, which includes capital appreciation as well as income, as
is consistent with prudent investment management.
 
    SUB-ADVISER:  AAM serves as Sub-Adviser to the Investment Grade Income Fund.
See "Equity Index Fund" for more information about AAM.
 
    INVESTMENT POLICIES:  The Fund will invest its assets in the following money
market instruments and debt securities.
 
    MONEY MARKET INSTRUMENTS:
 
        (a) Obligations issued  or guaranteed by  the United States  Government,
           its agencies or instrumentalities;
 
        (b)   Commercial  paper  rated  Prime-1  by  Moody's  Investors  Service
           ("Moody's"), or  A-l  by  S&P  or  unrated,  but  determined  by  the
           Sub-Adviser to be of comparable quality;
 
        (c)  Bankers acceptances or negotiable certificates of deposit issued by
           the 25 largest U.S. banks (in terms of deposits); and
 
        (d) Cash and cash equivalents.
 
    DEBT SECURITIES:
 
        (a) Obligations issued  or guaranteed by  the United States  Government,
           its agencies or instrumentalities,
 
        (b)  Debt securities which are  rated Aaa, Aa, A,  or Baa by Moody's, or
           AAA, AA,  A  or  BBB  by  S&P  or  unrated,  but  determined  by  the
           Sub-Adviser to be of comparable quality;
 
        (c)  Obligations (payable  in U.S.  dollars) of,  or guaranteed  by, the
           Government  of   Canada  or   of  a   Province  of   Canada  or   any
           instrumentality or political subdivision thereof.
 
    The  Fund may engage  in the options and  futures strategies described under
"Certain Investment Strategies and Policies."
 
                                       13
<PAGE>
   
    The debt securities in which the Fund may invest are considered  "investment
grade"  in that they  are generally suitable for  purchase by prudent investors.
However, the  lowest  category of  investment  grade securities  (rated  Baa  by
Moody's  or BBB by S&P) may  have speculative characteristics, such that 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 of
debt securities  with higher  ratings. The  portfolio of  the Fund  is  actively
managed  by AAM, as Sub-Adviser, in order  to anticipate events leading to price
or ratings changes. If the rating of a security falls below investment grade, or
an unrated  security  is deemed  to  have  fallen below  investment  grade,  AAM
analyzes  relevant economic and market data in making a determination of whether
to retain or dispose of the investment. The performance of the securities in the
portfolio is  monitored  continuously,  and  they  are  purchased  and  sold  as
conditions warrant and permit.
    
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the  Fund  was  126%.  The  portfolio  turnover  rate  exceeded  100%  due  to a
restructuring of the Fund's mortgaged-backed securities. The portfolio  turnover
rate  for the Fund may vary greatly from year to year. A high portfolio turnover
rate may result in greater brokerage costs to the Fund.
    
 
    See the Appendix  to the  Prospectus for an  explanation of  the ratings  of
Moody's and S&P.
 
GOVERNMENT BOND FUND
 
   
    INVESTMENT   OBJECTIVE:    The  Government  Bond  Fund  seeks  high  income,
preservation  of  capital  and   maintenance  of  liquidity  primarily   through
investments  in debt instruments issued or  guaranteed by the U.S. Government or
its agencies or instrumentalities ("U.S. Government securities") and in  related
options,  futures and repurchase  agreements. Under normal  conditions, at least
80% of the Fund's assets will be invested in U.S. Government securities.
    
 
    SUB-ADVISER:  AAM  serves as Sub-Adviser  to the Government  Bond Fund.  See
"Equity Index Fund" for more information about AAM.
 
    INVESTMENT  POLICIES:   Some  U.S. Government  securities, such  as Treasury
bills, notes and bonds, which differ  only in their interest rates,  maturities,
and  times of issuance, are supported by the full faith and credit of the United
States. Other U. S. Government securities are supported by (i) the right of  the
issuer  to borrow from the U.S. Treasury; (ii) discretionary authority of the U.
S. Government to purchase  the obligations of the  agency or instrumentality  or
(iii)  only the credit of the instrumentality itself. No assurances can be given
that the  U.S. Government  would provide  financial support  to U.S.  Government
sponsored instrumentalities if it is not obligated to do so by law. The Fund may
invest   in  mortgage-backed   government  securities,   including  pass-through
securities and participation  certificates of the  Government National  Mortgage
Association ("Ginnie Mae"), the Federal Home Loan Mortgage Corporation ("Freddie
Mac") and the Federal National Mortgage Association ("Fannie Mae").
 
   
    The  Government  Bond Fund  may invest  in any  other security  or agreement
collateralized or otherwise secured by U.S. Government securities. The Fund also
may invest in separately traded principal and interest components of  securities
guaranteed  or  issued  by  the  U.S. Treasury  if  such  components  are traded
independently under  the  Separate  Trading Registered  Interest  and  Principal
Securities  program. The Fund may enter into repurchase agreements, and may from
time  to  time  have  temporary  investments  in  short-term  debt   obligations
(including  certificates of  deposit, bankers acceptances  and commercial paper)
pending the making of other investments or for liquidity purposes.
    
 
    The Government Bond Fund may engage in several active management strategies,
including the lending of portfolio  securities, forward commitment purchases  of
securities,  writing covered  call and  covered put  options on  U.S. Government
securities, purchasing  such call  and put  options, and  entering into  closing
purchase  and sale  transactions. The  Fund also may  engage in  the options and
futures strategies described under "Certain Investment Strategies and Policies."
 
                                       14
<PAGE>
   
    U.S. Government securities may  be purchased or sold  without regard to  the
length  of time they have  been held to attempt  to take advantage of short-term
differentials in yields, with the  objective of seeking income while  conserving
capital.  While short-term trading increases  portfolio turnover, the Government
Bond Fund incurs little  or no brokerage costs  for U.S. Government  securities.
For the fiscal year ended December 31, 1995, the portfolio turnover rate for the
Fund  was 180%. The portfolio turnover rate  for the Fund increased from 106% in
1994 due  to  a  restructuring  of the  Fund's  mortgage-backed  securities.  In
addition,  U.S. Treasury  securities were sold  to fund the  purchase of various
asset-backed securities.
    
 
MONEY MARKET FUND
 
    INVESTMENT OBJECTIVE:  The Money Market Fund seeks to obtain maximum current
income consistent with preservation of capital and liquidity.
 
    SUB-ADVISER:   AAM serves  as  Sub-Adviser to  the  Money Market  Fund.  See
"Equity Index Fund" for more information about AAM.
 
    INVESTMENT  POLICIES:  The Fund seeks  to achieve its objective by investing
in the following high quality money market instruments:
 
        (a) Obligations issued  or guaranteed by  the United States  Government,
           its agencies or instrumentalities;
 
        (b)  Commercial paper which meets the  ratings requirements as set forth
           in the paragraph below;
 
   
        (c) Obligations  of banks  or  savings and  loan associations  (such  as
           bankers   acceptances   and   certificates   of   deposit,  including
           dollar-denominated obligations  of  foreign branches  of  U.S.  banks
           ("Eurodollars")  and U.  S. branches  of foreign  banks if  such U.S.
           branches are  subject  to  state  banking  requirements  and  Federal
           Reserve  reporting requirements) which at  the date of the investment
           have deposits  of at  least  $1 billion  as  of their  most  recently
           published financial statements;
    
 
        (d)  Repurchase agreements  with respect to  obligations described under
           (a) above (such obligations subject to repurchase agreement may  bear
           maturities  of more than  one year). For  more information concerning
           repurchase  agreements,  see   "Certain  Investment  Strategies   and
           Policies;"
 
        (e) Cash and cash equivalents.
 
    The Money Market Fund will not purchase any security unless (i) the security
has  received the highest  quality rating by at  least two nationally recognized
statistical rating organizations  ("NRSROs") or  by one  NRSRO if  only one  has
rated  the security, or (ii) the security is  unrated and in the opinion of AAM,
as Sub-Adviser, in accordance with guidelines  adopted by the Trustees, is of  a
quality  comparable to the highest  rating of an NRSRO.  These standards must be
satisfied at the time an  investment is made. If  the quality of the  investment
later  declines, the Fund may continue to  hold the investment, but the Trustees
will evaluate whether the  security continues to  present minimal credit  risks.
See the Appendix for examples of NRSRO ratings.
 
    The Fund will limit its portfolio investments to securities with a remaining
maturity  of  397  days as  of  the time  of  purchase, in  accordance  with the
Trustees' guidelines. The portfolio will be  managed so as to maintain a  dollar
weighted  maturity of  90 days or  less. In order  to maximize the  yield on its
assets, the Fund intends to be as  fully invested at all times as is  reasonably
practicable.
 
    There  is always the risk that the issuer  of an instrument may be unable to
make payment upon maturity.

                          MANAGEMENT FEES AND EXPENSES
 
   
    Under its Management Agreement with the  Trust, the Manager is obligated  to
perform  certain administrative and management services for the Trust, furnishes
to the Trust all necessary office space, facilities, and equipment and pays  the
compensation,  if  any, of  officers and  Trustees who  are affiliated  with the
Manager. Other than the expenses specifically  assumed by the Manager under  the
Management  Agreement, all expenses  incurred in the operation  of the Trust are
borne by the Trust, including fees and expenses associated with the registration
and qualification of the Trust's shares under the Securities Act of 1933,  other
fees  payable to the Securities  and Exchange Commission, independent accountant
fees, legal and  custodian fees, association  membership dues, taxes,  interest,
insurance premiums, brokerage commissions, fees and expenses of the Trustees who
are  not affiliated  with the Manager,  expenses for  proxies, prospectuses, and
reports to shareholders,  Fund recordkeeping  expenses and  other expenses.  The
Manager  has voluntarily  agreed to absorb  any charges  and expenses associated
with Fund recordkeeping that exceed 0.10% of a Fund's average net assets.
    
 
   
    For its services to the Funds,  the Manager receives fees computed daily  at
an  annual rate based on the  average daily net asset value  of each Fund as set
forth below:

    For its services  to the Government  Bond Fund, the  Manager receives a  fee
computed  daily at an annual rate of 0.50%  of the average daily net asset value
of such Fund.
 
   
    For its  services  to  the  Select  International  Equity  Fund  and  Select
Aggressive  Growth Fund, the Manager receives a  fee computed daily at an annual
rate of 1.00% of the average daily net asset value of each such Fund.
    
 
   
    The Manager  is  solely responsible  for  the payment  of  all fees  to  the
Sub-Advisers.  Each Sub-Adviser receives from the Manager fees computed daily at
an annual rate based on  the average daily net asset  value of each Fund as  set
forth  below.  For the  Select International  Equity Fund  and Growth  Fund, the
Sub-Adviser fee varies according to the level of assets in each such Fund, which
will reduce the  fees paid  by the  Manager as Fund  assets grow,  but will  not
reduce the operating expenses of the Fund.

    The Manager will voluntarily reimburse its  fees and any expenses above  the
expense limitations. The expense limitations are voluntary and may be removed at
any  time after a Fund's first fiscal  year of operation without prior notice to
existing shareholders. As shown above, all Funds are within expense  limitations
for  the year ended December 31, 1995. The Manager reserves the right to recover
from a Fund any fees, within a current fiscal year period, which were reimbursed
in that same year to  the extent that total annual  expenses did not exceed  the
applicable  expense  limitation.  Non-recurring and  extraordinary  expenses are
generally excluded  in the  determination of  expense ratios  of the  Funds  for
purposes  of determining any required expense reimbursement. Quotations of yield
or total return for any period when  an expense limitation is in effect will  be
greater than if the limitation had not been in effect.

    prior to joining AAM in May 1995.
    
 
                             HOW ARE SHARES VALUED?
 
    The  net asset value of the shares of  each Fund is determined once daily as
of the close  of the New  York Stock Exchange  (the "Exchange") on  each day  on
which the Exchange is open for trading.
 
    Equity  securities are valued on the basis  of their market value, if market
quotations are readily available. In other cases, they are valued at their  fair
value  as  determined  in  good  faith  by  the  Trustees,  although  the actual
calculations may be by persons acting pursuant to the direction of the Trustees.
Debt securities (other than short-term  obligations) are normally valued on  the
basis  of  valuations  formulated  by  a  pricing  service  which  utilizes data
processing  methods  to  determine  valuations  for  normal,  institutional-size
trading  units  of  such securities.  Such  methods  include the  use  of market
transactions  for  comparable  securities  and  various  relationships   between
securities   which  are  generally  recognized  by  institutional  traders.  All
securities of  the  Money  Market  Fund  are  valued  at  amortized  cost.  Debt
obligations  in the other Funds  having a remaining maturity  of 60 days or less
are valued  at  amortized  cost  when  it  is  determined  that  amortized  cost
approximates  fair value.  Short-term obligations  of the  other Funds  having a
remaining maturity of more than 60 days are marked to market based upon  readily
available market quotations for such obligations or similar securities
 
    Unlike  the Money Market Fund, which attempts to maintain a stable net asset
value, the net asset value of the other Funds will fluctuate.
 
                    TAXES AND DISTRIBUTIONS TO SHAREHOLDERS
 
   
    It is the policy of the Trust to comply with the provisions of the  Internal
Revenue Code applicable to regulated investment companies so that the Trust will
not  be subject to federal income tax on any net income and any capital gains to
the extent  they are  distributed or  are  deemed to  have been  distributed  to
shareholders.  Dividends out of net investment  income will be declared and paid
quarterly in the case  of the Growth Fund,  Equity Index Fund, Investment  Grade
Income  Fund  and Government  Bond  Fund; annually  in  the case  of  the Select
International Equity Fund and  Select Aggressive Growth Fund;  and daily in  the
case  of the Money Market Fund. Distributions  of net capital gains, if any, for
the year are  made annually. All  dividends and capital  gain distributions  are
applied  to purchase additional Fund shares at net asset value as of the payment
date. Fund shares are  held by the Separate  Accounts and any distributions  are
automatically reinvested by the Separate Accounts. Tax consequences to investors
in  the Separate Accounts which  are invested in the  Trust are described in the
prospectuses for such Accounts.
    
 
                         SALE AND REDEMPTION OF SHARES
 
   
    Shares of the Funds are sold in  a continuous offering and currently may  be
purchased  only by the Separate Accounts of First Allmerica or its subsidiaries.
The Separate Account is  the funding mechanism  for variable annuity  contracts.
The  Separate Account invests in  shares of one or more  of the Funds. Shares of
each Fund are sold at  their net asset value as  next computed after receipt  of
the  purchase order  without the  addition of  any selling  commission or "sales
load." The Distributor, Allmerica Investments, Inc., at its expense, may provide
promotional incentives to dealers that sell variable annuity contracts for which
the Funds serve as investment vehicles
    
 
   
    Shares of the Trust are also currently being issued to Separate Accounts  of
Allmerica  Life, First Allmerica and subsidiaries of First Allmerica which issue
variable or group annuity policies  or variable premium life insurance  policies
("mixed   funding").   Although   neither   Allmerica   Life   nor   the   Trust
    
 
                                       19
<PAGE>
   
currently foresees any disadvantage, it is  conceivable that in the future  such
mixed  funding may be disadvantageous for variable or group annuity policyowners
or variable premium life  insurance policyowners ("Policyowners"). The  Trustees
of  the Trust intend to  monitor events in order  to identify any conflicts that
may arise between such Policyowners and to determine what action, if any, should
be taken in  response thereto. If  the Trustees were  to conclude that  separate
funds  should be established  for variable annuity,  group annuity, and variable
premium life Separate Accounts, Allmerica Life will pay the attendant expenses.
    
 
    The Trust redeems  shares of  each Fund  at their  net asset  value as  next
computed  after receipt of the request  for redemption. The redemption price may
be more or less than the shareholder's cost.  No fee is charged by the Trust  on
redemption. The variable contracts funded through the Separate Accounts are sold
subject  to  certain fees  and charges  which may  include sales  and redemption
charges, described  in the  prospectus  or offering  circular for  the  Separate
Account.
 
    Redemption  payments will  be paid  within seven  days after  receipt of the
written request therefor by the Trust,  except that the right of redemption  may
be  suspended or  payments postponed  whenever permitted  by applicable  law and
regulations.
 
                         HOW IS PERFORMANCE DETERMINED?
 
    The Funds' performance may  be quoted in  advertising. A Fund's  performance
may be compared to the performance of other investments or relevant indices. All
performance  information is based  on historical results and  is not intended to
indicate future performance.
 
   
    For Funds  other  than the  Money  Market  Fund, "yield"  is  calculated  by
dividing  a Fund's  annualized net investment  income per share  during a recent
30-day period by the net asset value per  share on the last day of that  period.
For  the Money Market Fund, "yield" represents an annualization of the change in
value of  an  investment (excluding  any  capital changes)  in  the Fund  for  a
specific seven-day period; "effective yield" compounds that yield for a year and
is, for that reason, greater than the Fund's yield.
    
 
    Total  returns are based on the overall dollar or percentage change in value
of a hypothetical investment in a  Fund assuming all dividends and capital  gain
distributions  are  reinvested.  Cumulative  total  return  reflects  the Fund's
performance over a stated period of  time. Average annual total return  reflects
the  hypothetical annually compounded  return that would  have produced the same
cumulative return if the  Fund's performance had been  constant over the  entire
period.  Because average  annual returns  tend to  smooth out  variations in the
Fund's return, they are not the same as actual year-by-year results.
 
   
    YIELDS AND  TOTAL  RETURNS  QUOTED  FOR THE  FUNDS  INCLUDE  THE  EFFECT  OF
DEDUCTING  THE  FUNDS'  EXPENSES,  BUT  MAY  NOT  INCLUDE  CHARGES  AND EXPENSES
ATTRIBUTABLE TO A PARTICULAR INSURANCE PRODUCT. SINCE SHARES OF THE FUNDS CAN BE
PURCHASED ONLY THROUGH A  VARIABLE ANNUITY CONTRACT  OR VARIABLE LIFE  CONTRACT,
YOU  SHOULD  CAREFULLY  REVIEW  THE PROSPECTUS  FOR  THE  SEPARATE  ACCOUNTS FOR
INFORMATION ON RELEVANT  CHARGES AND  EXPENSES. INCLUDING THESE  CHARGES IN  THE
QUOTATIONS  OF  THE FUNDS'  YIELD  AND TOTAL  RETURN  WOULD HAVE  THE  EFFECT OF
DECREASING PERFORMANCE. PERFORMANCE  INFORMATION FOR  THE FUNDS  MUST ALWAYS  BE
ACCOMPANIED  BY, AND BE REVIEWED WITH,  PERFORMANCE INFORMATION FOR THE SEPARATE
ACCOUNTS WHICH INVEST IN THE FUNDS.
    
 
                  ORGANIZATION AND CAPITALIZATION OF THE TRUST
 
    The Trust was established as a  Massachusetts business trust under the  laws
of Massachusetts by an Agreement and Declaration of Trust dated October 11, 1984
(the  "Trust Declaration"). A copy of the  Trust Declaration is on file with the
Secretary of the Commonwealth of Massachusetts.
 
   
    The Trust  has  an  unlimited  authorized number  of  shares  of  beneficial
interest which may be divided into an unlimited number of series of such shares,
and  which  are  presently divided  into  twelve  series of  shares,  one series
underlying each Fund. Five  of the series are  not included in this  Prospectus.
The  Trust's shares are entitled to one vote per share (with proportional voting
for fractional
    
 
                                       20
<PAGE>
shares). The rights accompanying Fund shares are legally vested in the  Separate
Accounts.  As  a matter  of policy,  however, holders  of variable  premium life
insurance or variable  annuity contracts  funded through  the Separate  Accounts
have the right to instruct the Separate Accounts as to voting Fund shares on all
matters  to be voted on by Fund  shareholders. Voting rights of the participants
in the Separate Accounts are more fully set forth in the prospectus or  offering
circular  relating to the Separate Accounts.  See "Organization of the Trust" in
the SAI for the definition of a "majority vote" of shareholders.
 
    The Trust  is not  required to  hold annual  meetings of  shareholders.  The
Trustees or shareholders holding at least 10% of the outstanding shares may call
special meetings of shareholders.
 
   
FUND RECORDKEEPING AGENT
    
 
   
    First  Data, a wholly-owned subsidiary of First Data Corporation, calculates
net asset value  per share  and maintains  general accounting  records for  each
Fund.  First Data is entitled to receive  an annual Fund recordkeeping fee based
on Fund assets and certain out-of-pocket expenses.
    
 
CUSTODIAN
 
   
    Bankers Trust Company, 130 Liberty Street, New York, New York 10006, is  the
Custodian of the securities and other assets of the Trust.
    
 
                            INVESTMENT RESTRICTIONS
 
    The  following is a description of certain investment restrictions which are
fundamental and may not  be changed with respect  to a Fund without  shareholder
approval.  For a description of certain other investment restrictions, reference
should be made to the SAI.
 
        1.  No Fund will  concentrate its investments in particular  industries,
    including  debt obligations of foreign governments, but a Fund may invest up
    to 25%  of the  value of  its total  assets in  a particular  industry.  The
    restriction   does  not  apply  to  investments  in  obligations  issued  or
    guaranteed  by   the   United   States   of   America,   its   agencies   or
    instrumentalities,  or to investments by the Money Market Fund in securities
    issued or guaranteed by domestic branches of U.S. banks.
 
        2.  As  to 75%  of the value  of its  total assets (100%  for the  Money
    Market  Fund), no Fund  will invest more than  5% of the  value of its total
    assets in the securities of any one issuer (other than securities issued  by
    or guaranteed as to principal or interest by the United States Government or
    any  agency  or instrumentality  thereof) or  acquire more  than 10%  of the
    voting securities of any issuer. The remaining 25% of assets (other than for
    the Money Market  Fund) may be  invested in  the securities of  one or  more
    issuers without regard to such limitations.
 
   
    These limitations apply as of the time of purchase. If through market action
the percentage limitations are exceeded, the Fund will not be required to reduce
the amount of its holding in such investments.
    
 
                   CERTAIN INVESTMENT STRATEGIES AND POLICIES
 
REPURCHASE AGREEMENTS (APPLICABLE TO ALL FUNDS)
 
    Each Fund may invest in repurchase agreements, under which the Fund acquires
ownership  of a security (ordinarily U.S.  Government securities) but the seller
agrees, at the time of sale, to purchase the security at a mutually agreed  upon
time  and price. Should any seller of  a repurchase agreement fail to repurchase
the underlying security, or should any seller become insolvent or involved in  a
bankruptcy   proceeding,  a  Fund  could  incur  costs  and  losses.  Repurchase
Agreements maturing in  more than seven  days are  subject to the  15% limit  on
illiquid securities.
 
"WHEN-ISSUED" SECURITIES (APPLICABLE TO ALL FUNDS)
 
    Each  Fund  may purchase  securities on  a  when-issued or  delayed delivery
basis. Delivery  and  payment  normally take  place  15  to 45  days  after  the
commitment to purchase. No income accrues on
 
                                       21
<PAGE>
when-issued  securities prior  to delivery.  Purchase of  when-issued securities
involves the risk that yields available  in the market when delivery occurs  may
be higher than those available when the when-issued order is placed resulting in
a decline in the market value of the security. There is also the risk that under
some  circumstances the purchase  of when-issued securities  may act to leverage
the Fund.
 
LENDING OF SECURITIES (APPLICABLE TO ALL FUNDS)
 
   
    For the purpose of realizing additional income, the Funds may lend portfolio
securities to broker-dealers  or financial  institutions amounting  to not  more
than 30% of their respective total assets taken at current value. While any such
loan  is  outstanding, a  Fund will  continue  to receive  amounts equal  to the
interest or dividends paid by the issuer on the securities, as well as  interest
(less  any  rebates  to  be paid  to  the  borrower) on  the  investment  of the
collateral or a fee  from the borrower.  Each Fund will have  the right to  call
each  loan  and obtain  the  securities. Lending  portfolio  securities involves
certain risks, including possible delays  in receiving additional collateral  or
in  the recovery of the securities or  possible loss of rights in the collateral
should the borrower  fail financially.  Loans will  be made  in accordance  with
guidelines established by the Board of Trustees.
    
 
   
FOREIGN SECURITIES (APPLICABLE TO THE SELECT INTERNATIONAL EQUITY FUND, SELECT
AGGRESSIVE GROWTH FUND, GROWTH FUND AND EQUITY INDEX FUND)
    
 
   
    Investments  in  foreign  markets involve  substantial  risks  not typically
associated with investing in the U. S., which should be carefully considered  by
the  investor.  Such  risks  may  include  political  and  economic instability,
differing accounting and financial reporting standards, higher commission  rates
on  foreign portfolio  transactions, less  readily available  public information
regarding issuers,  potential  adverse  changes  in  tax  and  exchange  control
regulations  and the  potential for  restrictions on  the flow  of international
capital. Foreign  securities  also  involve  currency  risks.  Accordingly,  the
relative  strength  of  the  U.S.  dollar may  be  an  important  factor  in the
performance of  that  Fund,  depending  on the  extent  of  the  Fund's  foreign
investments.  Some  foreign  securities exchanges  may  not be  as  developed or
efficient as  those in  the U.S.  and securities  traded on  foreign  securities
exchanges  are generally subject to greater  price volatility. There is also the
possibility of adverse  changes in investment  or exchange control  regulations,
expropriation  or confiscatory taxation and limitations  on the removal of funds
or other assets. Investments in emerging countries involve exposure to  economic
structures  that are generally less diverse and mature than in the U. S., and to
political systems which may be less  stable. In addition, securities of  issuers
located in emerging countries may have limited market ability and may be subject
to more abrupt or erratic price fluctuations.
    
 
    The  Funds may buy  or sell foreign currencies  and foreign currency forward
contracts, options on foreign currencies and foreign currency futures  contracts
and  options thereon. Although such instruments may  reduce the risk of loss due
to a decline in  the value of the  currency which is sold,  they also limit  any
possible gain which might result should the value of the currency increase. Such
instruments  will be  used primarily to  protect the Fund  from adverse currency
movements; however,  they  also  involve  the  risk  that  anticipated  currency
movements  will not be accurately predicted, thus adversely affecting the Fund's
total return. See "Options and Futures Transactions."
 
    The Funds' investments may include ADRs. For many foreign securities,  there
are  U.S.  dollar-denominated ADRs  which  are traded  in  the United  States on
exchanges or over the counter. ADRs represent the right to receive securities of
foreign issuers deposited in a domestic bank or a correspondent bank. An ADR may
be sponsored by  the issuer of  the underlying  foreign security, or  it may  be
issued  in unsponsored form. The holder of  a sponsored ADR is likely to receive
more frequent and extensive financial  disclosure concerning the foreign  issuer
than  the holder of an unsponsored ADR and will generally bear lower transaction
charges. The Funds may invest in both sponsored and unsponsored ADRs.
 
                                       22
<PAGE>
   
RESTRICTED SECURITIES (APPLICABLE TO THE SELECT INTERNATIONAL EQUITY FUND AND
SELECT AGGRESSIVE GROWTH FUND)
    
 
   
    The Funds also may purchase fixed-income securities that are not  registered
under the Securities Act of 1933 ("1933 Act") ("restricted securities"), but can
be  offered and sold to "qualified institutional  buyers" under Rule 144A of the
1933 Act. However,  each Fund will  not invest more  than 15% of  its assets  in
restricted  securities (as  defined in  its investment  restrictions) unless the
Trust's Board of  Trustees determines,  based upon  a continuing  review of  the
trading  markets  for the  specific  restricted security,  that  such restricted
securities are  liquid.  The  Board  of  Trustees  has  adopted  guidelines  and
delegated  to  the  Manager the  daily  function of  determining  and monitoring
liquidity of restricted securities. The  Board, however, will retain  sufficient
oversight  and be ultimately responsible for the determinations. Since it is not
possible to  predict  with assurance  exactly  how this  market  for  restricted
securities  sold  and  offered under  Rule  144A  will develop,  the  Board will
carefully monitor  the  Funds'  investments  in  securities,  focusing  on  such
important  factors, among  others, as  valuation, liquidity  and availability of
information. This investment practice  could have the  effect of increasing  the
level  of illiquidity  in the  Fund to  the extent  that qualified institutional
buyers become for a time uninterested in purchasing these restricted securities.
As a result, the  Funds might not  be able to sell  these securities when  their
Sub-Adviser wishes to do so, or might have to sell them at less than fair value.
In  addition, market quotations are  less readily available. Therefore, judgment
may at times play a greater role in valuing these securities than in the case of
unrestricted securities.
    
 
OPTIONS AND FUTURES TRANSACTIONS (APPLICABLE TO EACH FUND EXCEPT THE MONEY
MARKET FUND)
 
    Through the writing and purchase of put and call options on its  securities,
financial  indices and foreign  currencies and the purchase  and sale of futures
contracts and related options with  respect to securities and financial  indices
in which it may invest, each Fund except the Money Market Fund may at times seek
to  hedge against fluctuations in net asset value. Each Fund's ability to engage
in options and  futures strategies  will depend  on the  availability of  liquid
markets  in such instruments. It is impossible  to predict the amount of trading
interest that  may exist  in  various types  of  options or  futures  contracts.
Therefore,  there is no assurance  that the Funds will  be able to utilize these
instruments effectively for the purposes stated above.
 
    Risks inherent in the use of futures and options ("derivative instruments"),
include (1) the risk that interest rates, securities prices and currency markets
will not move in the  directions anticipated; (2) imperfect correlation  between
the  price  of  derivative  instruments  and  movements  in  the  prices  of the
securities, interest rates or currencies being hedged; (3) the fact that  skills
needed  to  use  these strategies  are  different  from those  needed  to select
portfolio securities; (4) the possible absence of a liquid secondary market  for
any  particular  instrument at  any time;  and  (5) the  possible need  to defer
closing out certain hedged positions to avoid adverse tax consequences.
 
    The Funds will purchase futures and  options only on exchanges or boards  of
trade  when there appears to be an active  secondary market, but there can be no
assurance that a liquid secondary market will exist for any futures or option at
any particular time.
 
    In connection with transactions  in futures and  related options, the  Funds
will  be  required to  deposit  as "initial  margin"  an amount  of  cash and/or
securities. Thereafter, subsequent payments are made  to and from the broker  to
reflect changes in the value of the futures contract.
 
    A  more  detailed  explanation  of  futures,  options  and  other derivative
instruments, and the risks associated with them, is included in the SAI.
 
INVESTMENTS IN MONEY MARKET SECURITIES (APPLICABLE TO ALL FUNDS)
 
    Any Fund may hold at  least a portion of its  assets in cash equivalents  or
money  market instruments. There is  always the risk that  the issuer of a money
market instrument may be unable to make payment upon maturity.
 
    The Money Market Fund may hold uninvested cash reserves pending  investment,
during  temporary defensive  periods or if,  in the opinion  of the Sub-Adviser,
suitable securities are not available for
 
                                       23
<PAGE>
investment. Securities in which the Money Market Fund may invest may not earn as
high a level  of current  income as long-term,  lower-quality securities  which,
however, generally have less liquidity, greater market risk and more fluctuation
in market value.
 
ASSET-BACKED SECURITIES AND MORTGAGE-BACKED SECURITIES (APPLICABLE TO THE
INVESTMENT GRADE INCOME FUND AND GOVERNMENT BOND FUND)
 
    The   Funds  may   purchase  asset-backed  securities,   which  represent  a
participation in,  or are  secured by  and payable  from, a  stream of  payments
generated  by  particular assets,  frequently a  pool of  assets similar  to one
another. Assets  generating  such payments  include  instruments such  as  motor
vehicle  installment  purchase  obligations, credit  card  receivables  and home
equity loans. Payment of  principal and interest may  be guaranteed for  certain
amounts and time periods by a letter of credit issued by a financial institution
unaffiliated  with  the  issuer of  the  securities.  The estimated  life  of an
asset-backed security varies  with the prepayment  experience of the  underlying
debt  instruments.  The rate  of such  prepayments,  and hence  the life  of the
assetbacked security,  will be  primarily a  function of  current market  rates,
although  other economic and demographic factors will be involved. Under certain
interest rate and prepayment rate scenarios, the Funds may fail to recoup  fully
their investment in asset-backed securities. Each Fund will not invest more than
10% of its total assets in asset-backed securities.
 
   
    The  Funds  also may  invest in  mortgage-backed  securities which  are debt
obligations secured by  real estate loans  and pools of  loans on single  family
homes,   multi-family  homes,  mobile  homes,  and  in  some  cases,  commercial
properties. The Funds may acquire securities representing an interest in a  pool
of mortgage loans that are issued or guaranteed by a U.S. government agency such
as the Ginnie Mae, Fannie Mae and Freddie Mac.
    
 
    Mortgage-backed  securities  are in  most cases  "pass-through" instruments,
through which the holder receives a share of all interest and principal payments
from  the  mortgages   underlying  the  certificate.   Because  the   prepayment
characteristics  of the underlying mortgages vary, it is not possible to predict
accurately the  average  life  or  realized  yield  of  a  particular  issue  of
pass-through   certificates.  During   periods  of   declining  interest  rates,
prepayment of mortgages underlying mortgage-backed securities can be expected to
accelerate. When the mortgage  obligations are prepaid,  the Fund reinvests  the
prepaid  amounts  in  securities, the  yield  of which  reflects  interest rates
prevailing  at  the  time.  Moreover,  prepayment  of  mortgages  that  underlie
securities purchased at a premium could result in losses.
 
    The  Funds  also may  invest  in multiple  class  securities issued  by U.S.
government agencies and instrumentalities  such as Fannie  Mae, Freddie Mac  and
Ginnie  Mae, including  guaranteed collateralized  mortgage obligations ("CMOs")
and  Real  Estate   Mortgage  Investment  Conduit   ("REMIC")  pass-through   or
participation   certificates,  when   consistent  with   the  Funds'  investment
objectives, policies and  limitations. A CMO  is a  type of bond  secured by  an
underlying  pool  of mortgages  or mortgage  pass-through certificates  that are
structured to direct payments  on underlying collateral  to different series  or
classes  of  obligations.  A REMIC  is  a  CMO that  qualifies  for  special tax
treatment under  the Internal  Revenue  Code and  invests in  certain  mortgages
principally   secured  by  interests  in   real  property  and  other  permitted
investments.
 
    CMOs and guaranteed REMIC  pass-through certificates ("REMIC  Certificates")
issued  by  Fannie  Mae,  Freddie  Mac and  Ginnie  Mae  are  types  of multiple
pass-through securities. Investors may purchase beneficial interests in  REMICs,
which are known as "regular" interests or "residual" interests. The Funds do not
currently   intend  to  purchase   residual  interests  in   REMICS.  The  REMIC
Certificates  represent  beneficial  ownership  interests  in  a  REMIC   trust,
generally  consisting of mortgage loans or Fannie  Mae, Freddie Mac or Ginne Mae
guaranteed mortgage pass-through  certificates. The obligations  of Fannie  Mae,
Freddie  Mac  or  Ginnie  Mae  under  their  respective  guaranty  of  the REMIC
Certificates are obligations solely  of Fannie Mae, Freddie  Mac or Ginnie  Mae,
respectively.
 
                                       24

    Fannie  Mae  REMIC  Certificates  are issued  and  guaranteed  as  to timely
distribution of principal and  interest by Fannie Mae.  In addition, Fannie  Mae
will  be obligated to  distribute the principal  balance of each  class of REMIC
Certificates in full, whether or not sufficient funds are otherwise available.
 
    For Freddie  Mac  REMIC  Certificates, Freddie  Mac  guarantees  the  timely
payment  of interest, and  also guarantees the payment  of principal as payments
are required to be  made on the  underlying mortgage participation  certificates
("PCs"). PCs represent undivided interests in specified residential mortgages or
participation  therein purchased by  Freddie Mac and  placed in a  PC pool. With
respect to principal payments on PCs, Freddie Mac generally guarantees  ultimate
collection  of all  principal of  the related  mortgage loans  without offset or
deduction. Freddie Mac also  guarantees timely payment  of principal on  certain
PCs referred to as "Gold PCs."
 
    Ginnie  Mae  REMIC Certificates  guarantee the  full  and timely  payment of
interest and principal on each class of securities (in accordance with the terms
of those classes,  as specified  in the related  offering circular  supplement).
This  Ginnie Mae guarantee is backed by the  full faith and credit of the United
States of America.
 
    REMIC Certificates issued  by Fannie  Mae, Freddie  Mac and  Ginnie Mae  are
treated  as U.  S. government  securities for  purposes of  investment policies.
There can  be  no assurance  that  the  United States  government  will  provide
financial  support to Fannie Mae, Freddie Mac  or Ginnie Mae if necessary in the
future.
 
STRIPPED MORTGAGE-BACKED SECURITIES (APPLICABLE TO THE INVESTMENT GRADE INCOME
FUND AND GOVERNMENT BOND FUND)
 
    The Funds may invest in  Stripped Mortgage-Backed Securities ("SMBS").  SMBS
are derivative multiclass mortgage securities. SMBS may be issued by agencies or
instrumentalities  of  the  U.S. Government  or  by private  originators  of, or
investors in, mortgage loans, including savings and loan associations,  mortgage
banks,  commercial banks, investment  banks and special  purpose entities of the
foregoing.
 
   
    SMBS  are  usually  structured  with  two  classes  that  receive  different
proportions  of the interest  and principal distributions on  a pool of mortgage
assets. One type of SMBS 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 some  cases,
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 to 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 a  portfolio yield to maturity  from these securities. If  the
underlying  mortgage assets  experience greater than  anticipated prepayments of
principal, the Funds may fail to fully recoup their initial investment in  these
securities  even if  the security  is in one  of the  highest rating categories.
Certain SMBS may  be deemed "illiquid"  and subject to  a Fund's limitations  on
investment in illiquid securities. The market value of the PO class generally is
unusually  volatile in response  to changes in  interest rates. The  yields on a
class of SMBS that receives all or most of the interest from mortgage assets are
generally  higher  than  prevailing  market  yields  on  other   mortgage-backed
securities  because their cash  flow patterns are  more volatile and  there is a
greater risk that the  initial investment will not  be fully recouped. The  Sub-
Adviser will seek to manage these risks (and potential benefits) by investing in
a variety of such securities and by using certain hedging techniques.
    
 
   
HEDGING TECHNIQUES AND INVESTMENT PRACTICES (APPLICABLE TO THE SELECT
INTERNATIONAL EQUITY FUND)
    
 
   
    The  Select International Equity Fund may employ certain strategies in order
to manage exchange rate risks.  For example, the Fund may  hedge some or all  of
its investments denominated in a foreign currency against a decline in the value
of  that  currency. The  Fund  may enter  into  contracts to  sell  that foreign
currency for  U.S.  dollars  (not  exceeding the  value  of  the  Fund's  assets
denominated in that
    
 
                                       25
<PAGE>
   
currency)  or by participating  in options or futures  contracts with respect to
such currency ("position  hedge"). The Fund  also could hedge  that position  by
selling  a  second  currency, which  is  expected  to perform  similarly  to the
currency in which portfolio investments are denominated for U.S. dollars ("proxy
hedge"). The Fund also may enter into a forward contract to sell the currency in
which the security  is denominated  for a second  currency that  is expected  to
perform  better relative to the U.S. dollar if its Sub-Adviser believes there is
a reasonable  degree of  correlation  between movements  in the  two  currencies
("cross-hedge").  As an operational  policy, the Fund will  not commit more than
10% of its assets to the  consummation of cross-hedge contracts and will  either
cover currency hedging transactions with liquid portfolio securities denominated
in  the applicable currency or segregate high-grade, liquid assets in the amount
of such  commitments.  In  addition,  when  the  Fund  anticipates  repurchasing
securities  denominated  in a  particular currency,  the Fund  may enter  into a
forward contract to purchase such currency in exchange for the dollar or another
currency ("anticipatory hedge").
    
 
   
    These strategies minimize  the effect  of currency appreciation  as well  as
depreciation,  but do not protect  against a decline in  the underlying value of
the hedged security. In  addition, such strategies may  reduce or eliminate  the
opportunity  to profit from increases in the  value of the original currency and
may adversely impact the Fund's  performance if its Sub-Adviser's projection  of
future exchange rates is inaccurate.

COMMERCIAL PAPER RATINGS
 
    MOODY'S  EMPLOYS THREE DESIGNATIONS,  ALL JUDGED TO  BE INVESTMENT GRADE, TO
INDICATE THE  RELATIVE REPAYMENT  CAPACITY  OF RATED  ISSUERS. THE  TWO  HIGHEST
DESIGNATIONS ARE AS FOLLOWS:
 
        Issuers  rated  Prime-1  (or  related  supporting  institutions)  have a
    superior  capacity  for  repayment  of  short-term  promissory  obligations.
    Prime-1  repayment  capacity will  normally  be evidenced  by  the following
    characteristics:
 
        -- Leading market positions in well-established industries.
 
        -- High rates of return on funds employed.
 
        -- Conservative capitalization structures with moderate reliance on debt
           and ample asset protection.
 
        -- Broad margins in  earnings coverage  of fixed  financial charges  and
           high internal cash generation.
 
        -- Well-established  access to a range  of financial markets and assured
           sources of alternate liquidity.
 
        Issuers rated Prime-2 (or related supporting institutions) have a strong
    capacity for repayment of  short-term promissory obligations. This  normally
    will  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  alternate
    liquidity is maintained.
 
   
    S&P  COMMERCIAL PAPER  RATINGS ARE  GRADED INTO  SEVERAL CATEGORIES, RANGING
FROM "A-1" FOR THE HIGHEST  QUALITY OBLIGATIONS TO "D"  FOR THE LOWEST. THE  TWO
HIGHEST RATING CATEGORIES ARE DESCRIBED AS FOLLOWS:
    
 
   
        A-1  --  This  highest  category indicates  that  the  degree  of safety
    regarding timely  payment  is strong.  Those  issues determined  to  possess
    extremely  strong safety  characteristics are denoted  with a  plus (+) sign
    designation.
    
 
   
        A-2 -- Capacity for  timely payment on issues  with this designation  is
    satisfactory.  However, the relative degree of safety  is not as high as for
    issues designated A-1.
    
 
MUNICIPAL OBLIGATIONS
 
    Moody's ratings for  state and  municipal and  other short-term  obligations
will  be designated  Moody's Investment  Grade ("MIG").  This distinction  is in
recognition of  the differences  between short-term  credit risk  and  long-term
risk.  Factors  affecting  the  liquidity  of  the  borrower  are  uppermost  in
importance in  the short-term  borrowing,  while various  factors of  the  first
importance in long-term borrowing risk are of lesser importance in the long run.
Symbols used will be as follows:
 
   
        MIG-1  -- This designation denotes best quality. There is present strong
    protection  by  established  cash  flows,  superior  liquidity  support   or
    demonstrated broad-based access to the market for refinancing.
    
 
   
        MIG-2  -- This designation  denotes high quality.  Margins of protection
    are ample although not so large as in the preceding group.
    
 
    A short-term  rating  may also  be  assigned on  an  issue having  a  demand
feature. Such ratings will be designated as VMIG to reflect such characteristics
as  payment upon  periodic demand rather  than fixed maturity  dates and payment
relying  on  external  liquidity.   Additionally,  investors  should  be   alert
 
                                       27
<PAGE>
   
to  the fact that the source of payment may be limited to the external liquidity
with no or limited legal recourse to the issuer in the event that demand is  not
met.  VMIG-1 and VMIG-2 ratings  carry the same definitions  as MIG-1 and MIG-2,
respectively.
    
 
DESCRIPTION OF MOODY'S BOND RATINGS
 
   
    AAA -- Bonds that are rated Aaa are  judged to be of the best quality.  They
carry  the smallest degree of  investment risk and are  generally referred to as
"gilt edge". Interest payments are protected  by a large or by an  exceptionally
stable margin and principal is secure. While the various protective elements are
likely  to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.
    
 
   
    AA -- Bonds  that are  rated Aa  are judged  to be  of high  quality by  all
standards.  Together with the Aaa group,  they comprise what are generally known
as high-grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be  of greater  amplitude or there  may be  other elements  present
which make the long-term risks appear somewhat larger than in Aaa securities.
    
 
   
    A -- Bonds that are rated A possess many favorable investment attributes and
are  to be considered as upper medium grade obligations. Factors giving security
to principal and interest are considered  adequate, but elements may be  present
that suggest a susceptibility to impairment some time in the future.
    
 
   
    BAA  -- Bonds that are rated Baa are considered as medium grade obligations,
i.e., they are neither  highly protected nor  poorly secured. Interest  payments
and  principal security appear  adequate for the  present but certain protective
elements may be lacking or may  be characteristically unreliable over any  great
length  of time. Such  bonds lack outstanding  investment characteristics and in
fact have speculative characteristics as well.
    
 
   
    BA -- Bonds that are rated Ba are judged to have speculative elements; their
future cannot be considered  as well assured. Often  the protection of  interest
and  principal payments  may be very  moderate and thereby  not well safeguarded
during both  good  and  bad  times over  the  future.  Uncertainty  of  position
characterizes bonds in this class.
    
 
   
    B  -- Bonds that are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or maintenance of other
terms of the contract over any long period of time may be small.
    
 
   
    Those bonds within the Aa, A, Baa, Ba and B categories that Moody's believes
possess the strongest credit attributes  within those categories are  designated
by the symbols Aa1, A1, Baa1, Ba1 and B1.
    
 
   
DESCRIPTION OF S&P'S DEBT RATINGS
    
 
   
    AAA  -- Debt rated AAA  has the highest rating  assigned by S&P. Capacity to
pay interest and repay principal is extremely strong.
    
 
   
    AA -- Debt rated  AA has a  very strong capacity to  pay interest and  repay
principal and differs from AAA issues only in a 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. Where as 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.
    
 
                                       28
<PAGE>
   
    BB, B, CCC, CC,  C -- Debt  rated BB, B,  CCC, CC, C  is regarded as  having
predominantly  speculative  characteristics  with  respect  to  capacity  to pay
interest and repay principal. BB indicates the least degree of speculation and C
the highest.  While such  debt  will likely  have  some quality  and  protective
characteristics,  these are outweighed by large uncertainties or major exposures
to adverse conditions.
    
 
    PLUS (+) OR (-):  The ratings from AA to CCC may be modified by the addition
of a plus or minus sign to show relative standing within the major categories.

                           HOW ARE THE FUNDS MANAGED?
 
    The overall responsibility for the supervision  of the affairs of the  Trust
vests  in the  Board of  Trustees of the  Trust who  meet on  a quarterly basis.
Allmerica Investment Management Company, Inc. (the "Manager") is responsible for
the management  of  the Trust's  day-to-day  business affairs  and  has  general
responsibility  for the management of the investments of the Funds. The Manager,
at  its  expense,  has  contracted  with  certain  Sub-Advisers  to  manage  the
investments  of the Funds subject to  the requirements of the Investment Company
Act of 1940 (the "1940 Act").
 
   
    The Manager  is  a  wholly-owned  subsidiary  of  First  Allmerica,  a  life
insurance  company, which was  organized in Massachusetts  in 1844. The Manager,
organized August 19,  1985, also serves  as manager of  the Allmerica Funds,  an
open-end  investment company. The Manager and First Allmerica are located at 440
Lincoln Street, Worcester, Massachusetts 01653.
    
 
   
    The Manager has entered  into Sub-Adviser Agreements  for the management  of
the  investments of each of the Funds.  The Sub-Advisers, who have been selected
on the basis  of various  factors, including  management experience,  investment
techniques and staffing, are each authorized to engage in portfolio transactions
on  behalf  of  the  applicable  Funds  subject  to  such  general  or  specific
instructions as may be given by the Trustees and/or the Manager. The terms of  a
Sub-Adviser  Agreement  cannot be  changed without  the  approval of  a majority
interest of the shareholders  of the affected Fund.  The Sub-Advisers have  been
selected  by the Manager and  the Trustees in consultation  with Rogers, Casey &
Associates ("Rogers, Casey"),  a leading  pension consulting firm.  The cost  of
such consultation is borne by the Manager.
    
 
    Rogers,  Casey provides  consulting services  to pension  plans representing
over $150 billion in total assets and, in its consulting capacity, monitors  the
investment  performance of  over 1,000  investment advisers.  From time  to time
specific clients of Rogers, Casey and the Sub-Advisers will be provided in sales
materials.  At  times,  Rogers,  Casey  assists  in  the  development  of  asset
allocation  strategies which may be used  by shareholders in the diversification
of their portfolio across different asset classes.
 
   
    Ongoing  performance  of  the  independent  Sub-Advisers  is  reviewed   and
evaluated  by  a  committee  whose  members  may  be  senior  officers  of First
Allmerica,  its  affiliates  or  the  Manager  and  an  independent  consultant.
Combined,  the committee has over 150 years of investment experience. Historical
performance data for all of the Funds is set forth in the "Financial Highlights"
tables on Page 3. The Manager is solely responsible for the payment of all  fees
to the Sub-Advisers. The Sub-Advisers for each of the Funds are as follows:

    For   a  sample  listing  of  the  Sub-Advisers'  clients,  see  "Investment
Management and Other Services" in the SAI.  For more information on each of  the
Sub-Advisers  see "What Are  the Investment Objectives  and Policies?" and "Fund
Manager Information."
    
 
   
    The Manager also has entered into an Administrative Services Agreement  with
First  Data  Investor  Services  Group,  Inc.  ("First  Data"),  a  wholly-owned
subsidiary of First Data Corporation, whereby First Data performs administrative
services for each of the Funds and is entitled to receive an administrative  fee
and  certain out-of-pocket expenses.  The Manager is  solely responsible for the
payment of the administrative fee to First Data.
    
 
                WHAT ARE THE INVESTMENT OBJECTIVES AND POLICIES?
 
    Each Fund has a separate investment objective and policies designed to  meet
different  investment  and  financial needs,  as  described below.  There  is no
assurance that a Fund will achieve its investment objective.
 
                                       4
<PAGE>
   
    Each Fund  may invest  up  to 15%  of its  assets  in securities  which  are
illiquid  because they are subject to restriction  on resale or for which market
quotations are  not readily  available. The  Select Aggressive  Growth Fund  may
invest  up  to 25  %  of its  assets in  foreign  securities (not  including its
investments  in   American  Depositary   Receipts  ("ADRs"))   and  the   Select
International  Equity Fund  may invest any  percentage of its  assets in foreign
securities. See "Certain Investment Strategies and Policies." Each Fund also may
invest in fixed-income securities. Fixed-income  securities rated in the  fourth
highest  grade  by Moody's  Investors Service,  Inc.  ("Moody's") or  Standard &
Poor's Ratings Service, a division  of McGraw-Hill Companies, Inc. ("S&P")  (Baa
and  BBB, respectively)  are investment  grade but  are considered  to have some
speculative  characteristics.  For  more   information  concerning  the   rating
categories of fixed-income securities see the Appendix.
    
 
    A  Fund's investment objective is fundamental and may not be changed without
shareholder approval. Unless otherwise  indicated, a Fund's investment  policies
are not fundamental and may be changed without shareholder approval.
 
SELECT INTERNATIONAL EQUITY FUND
 
    INVESTMENT  OBJECTIVE:  The  Select International Equity  Fund seeks maximum
long-term total return (capital appreciation and income) primarily by  investing
in common stocks of established non-U S. companies.
 
   
    SUB-ADVISER:    Bank of  Ireland  Asset Management  (U.S.)  Limited ("BIAM")
serves as  Sub-Adviser for  the Select  International Equity  Fund. BIAM  is  an
indirect  wholly-owned subsidiary of Bank of Ireland. Its main offices are at 26
Fitzwilliam Place, Dublin  2, Ireland.  Its U.S.  offices are  at Two  Greenwich
Plaza,  Greenwich, C  T 06830.  Bank of  Ireland provides  investment management
services through a network of sister companies, including BIAM which  represents
North  American  clients.  As of  December  31,  1995, Bank  of  Ireland managed
approximately $15  billion  in  global securities  for  Irish,  United  Kingdom,
European and U.S. clients.
    
 
    INVESTMENT  POLICIES:   To achieve  its objective,  the Select International
Equity Fund  will invest  primarily  in common  stocks of  established  non-U.S.
companies.  Under normal market  conditions, at least  65 % of  the Fund's total
assets will be  invested in the  securities of companies  domiciled in at  least
five  foreign  countries, not  including the  United States.  The Fund  may also
acquire fixed income debt securities. It will do so, at the discretion of  BIAM,
primarily for defensive purposes.
 
    The   Fund's  investments  may  include  ADRs  which  may  be  sponsored  or
unsponsored by  the  underlying  issuer.  The Fund  may  also  utilize  European
Depositary  Receipts  ("EDRs"),  which  are similar  to  ADRs,  in  bearer form,
designed for  use  in the  European  securities markets  and  Global  Depositary
Receipts  ("GDRs"). Investments in foreign securities carry additional risks not
present  in  domestic  securities.   See  "Certain  Investment  Strategies   and
Policies-Foreign Securities. " The Fund may, for hedging purposes, engage in the
options  and futures  strategies described under  "Certain Investment Strategies
and  Policies."  Certain  state  insurance  regulations  may  impose  additional
restrictions on the Fund's holdings of foreign securities.
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the Fund was 24%. The portfolio turnover rate for the Fund may vary greatly from
year to year.
    
 
SELECT AGGRESSIVE GROWTH FUND
 
    INVESTMENT OBJECTIVE:  The Select Aggressive Growth Fund seeks above-average
capital  appreciation by investing primarily in common stocks of companies which
are believed to have significant potential for capital appreciation.
 
   
    SUB-ADVISER:   Nicholas-Applegate  Capital  Management  ("NACM")  serves  as
Sub-Adviser  to the Select Aggressive Growth Fund. NACM is an investment manager
supervising accounts  with  approximately $29  billion  in total  assets  as  of
December 31, 1995. NACM's clients are primarily major
    
 
                                       5
<PAGE>
   
corporate  employee benefit funds, public employee retirement plans, foundations
and endowment funds, investment companies and individuals. Founded in 1984, NACM
is located at 600 West Broadway, Suite 2900, San Diego, California 92101.
    
 
   
    INVESTMENT POLICIES:  Under normal circumstances, at least 65% of the assets
of the Select  Aggressive Growth  Fund will  be invested  in equity  securities,
consisting   of  common  stocks,  securities   convertible  into  common  stocks
(including bonds, notes and  preferred stocks) and  warrants. The Fund's  assets
may  also be invested  in other debt  securities and preferred  stocks when such
securities are believed appropriate in light of the Fund's investment  objective
and market conditions.
    
 
    The  selection of securities is made solely  on the basis of their potential
for capital appreciation. Dividend and  interest income, if any, from  portfolio
securities  is incidental to the  Fund's investment objective. While investments
may be made in  well-known and established companies,  a significant portion  of
the  Fund's investments is expected to be  in securities of newer and relatively
unseasoned companies or companies which represent new or changing industries.
 
    At any given point  a substantial portion of  the Fund's equity  investments
may  be in securities  which are not  listed for trading  on national securities
exchanges  and  which,  although  publicly  traded,  may  be  less  liquid  than
securities  issued by  larger, more seasoned  companies which  trade on national
securities exchanges.  Up  to  15% of  the  Fund's  assets may  be  invested  in
restricted or illiquid securities.
 
    Securities  of newer companies may be closely held with only a small portion
of their outstanding securities owned by the general public. Newer companies may
have relatively small revenue, lack depth  of management and have a small  share
of  the market for their products or services; thus, they may be more vulnerable
to changes  in  economic  conditions,  market  fluctuations  and  other  factors
affecting  the profitability  or marketability  of companies.  Due to  these and
other factors, the  price movement of  the securities  held by the  Fund can  be
expected to be more volatile than is the case for the market as a whole, and the
net   asset  value  of  a  share   of  the  Fund  may  fluctuate  significantly.
Consequently, the Fund should not be  considered suitable for investors who  are
unable  or unwilling to assume the risk of loss inherent in an aggressive growth
portfolio, nor  should  investment in  the  Fund  be considered  a  balanced  or
complete investment proram.
 
   
    When  NACM determines that  market conditions warrant  a temporary defensive
position, the Fund  may invest  without limitation  in high-grade,  fixed-income
securities,  U.S.  Government  securities,  or  hold  assets  in  cash  or  cash
equivalents. The  Fund may,  for hedging  purposes, engage  in the  options  and
futures strategies described under "Certain Investment Strategy and Policies."
    
 
   
    For the fiscal year ended December 31, 1995, the portfolio turnover rate for
the   Fund  was  104%.  The  portfolio   turnover  rate  was  104%  because  the
Sub-Adviser's investment approach typically  results in above-average  portfolio
turnover  as securities are  sold when the Sub-Adviser  believes the reasons for
their initial purchase are no longer valid or when it believes that the sale  of
a  security owned by the  Fund and the purchase  of another security can enhance
return. A security may be sold to avoid a prospective decline in market value or
purchased in  anticipation of  a market  rise. Although  it is  not possible  to
predict  future portfolio  turnover rates  accurately, and  such rates  may vary
greatly from year to year, NACM  anticipates that the annual portfolio  turnover
generally  will  not exceed  100%. A  high portfolio  turnover rate  will likely
result in greater brokerage costs to the Fund.
    
 
                          MANAGEMENT FEES AND EXPENSES
 
    Under its Management Agreement with the  Trust, the Manager is obligated  to
perform  certain administrative and management services for the Trust, furnishes
to the Trust all necessary office space, facilities, and equipment, and pays the
compensation, if  any, of  officers and  Trustees who  are affiliated  with  the
Manager.  Other than the expenses specifically  assumed by the Manager under the
Management Agreement, all expenses  incurred in the operation  of the Trust  are
borne by the Trust, including fees and expenses associated with the registration
and qualification of the Trust's shares
 
                                       6
<PAGE>
under  the Securities  Act of  1933, other  fees payable  to the  Securities and
Exchange Commission,  independent accountant  fees,  legal and  custodian  fees,
association  membership  dues,  taxes, interest,  insurance  premiums, brokerage
commissions, fees and expenses of the  Trustees who are not affiliated with  the
Manager,  expenses for proxies, prospectuses,  and reports to shareholders, Fund
recordkeeping expenses and other expenses. The Manager has voluntarily agreed to
absorb any charges and expenses  associated with Fund recordkeeping that  exceed
0.10% of a Fund's average net assets.
 
    For  its services  to the  Select International  Equity Fund  and the Select
Aggressive Growth Fund, the  Manager receives fees computed  daily at an  annual
rate of 1.00% of the average daily net asset value of each such Fund.
 
    The  Manager  is solely  responsible  for the  payment  of all  fees  to the
Sub-Advisers. For its  services, BIAM will  receive a fee  computed daily at  an
annual  rate based on the  average daily net assets  of the Select International
Equity Fund, under the following schedule:
 
<TABLE>

</TABLE>
 
    BIAM's  fee  varies  according  to  the  level  of  assets  in  the   Select
International  Equity Fund, which  will reduce the  fees paid by  the Manager as
Fund assets grow, but will not reduce the operating expenses of such Fund.
 
    The Manager pays NACM a fee computed daily at an annual rate of 0.60% of the
average daily net asset value of the Select Aggressive Growth Fund.
 
   
    For the fiscal  year ended  December 31, 1995,  each Fund  paid the  Manager
gross  fees before reimbursement at a rate of 1.00% of such Fund's average daily
net assets.
    
 
   
    The following table  shows voluntary expense  limitations which the  Manager
has  declared for each Fund  and the operating expenses  incurred for the fiscal

    The Manager will voluntarily reimburse its  fees and any expenses above  the
expense limitations. The expense limitations are voluntary and may be removed at
any  time after a Fund's first fiscal  year of operation without prior notice to
existing shareholders. As shown above, both Funds are within expense limitations
for the year ended December 31, 1995. The Manager reserves the right to  recover
from a Fund any fees, within a current fiscal year period, which were reimbursed
in  that same year to  the extent that total annual  expenses did not exceed the
applicable expense  limitation.  Non-recurring and  extraordinary  expenses  are
generally  excluded  in the  determination of  expense ratios  of the  Funds for
determining any required  expense reimbursement.  Quotations of  yield or  total
return  for any period when  an expense limitation is  in effect will be greater
than if the limitation had not been in effect.

                             HOW ARE SHARES VALUED
    
 
    The net asset value of the shares  of each Fund is determined once daily  as
of  the close  of the New  York Stock Exchange  (the "Exchange") on  each day on
which the Exchange is open for trading.
 
    Equity securities are valued on the  basis of their market value, if  market
quotations  are readily available. In other cases  they are valued at their fair
value as  determined  in  good  faith  by  the  Trustees,  although  the  actual
calculations  may be  made by  persons acting pursuant  to the  direction of the
Trustees. Debt  securities  (other  than short-term  obligations)  are  normally
valued on the basis of valuations formulated by a pricing service which utilizes
data  processing methods to determine  valuations for normal, institutional-size
trading units  of  such securities.  Such  methods  include the  use  of  market
transactions   for  comparable  securities  and  various  relationships  between
securities  which  are  generally  recognized  by  institutional  traders.  Debt
obligations in Funds having a remaining
 
                                       8
<PAGE>
maturity  of 60 days or less are valued  at amortized cost when it is determined
that amortized cost  approximates fair  value. Short-term  obligations of  Funds
having a remaining maturity of more than 60 days are marked to market based upon
readily available market quotations for such obligations or similar securities.
 
    The net asset value of the Funds will fluctuate.
 
                    TAXES AND DISTRIBUTIONS TO SHAREHOLDERS
 
    It  is the policy of the Trust to comply with the provisions of the Internal
Revenue Code applicable to regulated investment companies so that the Trust will
not be subject to federal income tax on any net income and any capital gains  to
the  extent  they are  distributed or  are  deemed to  have been  distributed to
shareholders. Dividends out of net investment  income will be declared and  paid
annually.  Distributions of  net capital  gains, if any,  for the  year are made
annually. All dividends and capital  gain distributions are applied to  purchase
additional  Fund shares at net  asset value as of  the payment date. Fund shares
are held  by  the Separate  Accounts  and any  distributions  are  automatically
reinvested  by  the  Separate Accounts.  Tax  consequences to  investors  in the
Separate Accounts  which  are  invested  in  the  Trust  are  described  in  the
prospectus or offering circular for such Accounts.
 
                         SALE AND REDEMPTION OF SHARES
 
   
    Shares  of the Funds are sold in  a continuous offering and currently may be
purchased only by Separate Accounts established by First Allmerica. The Separate
Accounts are the funding  mechanisms for group  annuity contracts. The  Separate
Accounts  invest in shares of one or more  of the Funds. Shares of each Fund are
sold at their net  asset value as  next computed after  receipt of the  purchase
order without the addition of any selling commission or "sales load".
    
 
   
    Shares  of the Trust are also currently being issued to Separate Accounts of
Allmerica Financial Life  Insurance and  Annuity Company  ("Allmerica Life"),  a
subsidiary  of First Allmerica, First Allmerica  and other subsidiaries of First
Allmerica which issue  variable or  group annuity policies  or variable  premium
life  insurance policies ("mixed funding").  Although neither Allmerica Life nor
the Trust currently  foresees any disadvantage,  it is conceivable  that in  the
future  such mixed funding may be  disadvantageous for variable or group annuity
policyowners or variable premium  life insurance policyowners  ("Policyowners").
The  Trustees of  the Trust intend  to monitor  events in order  to identify any
conflicts that may arise between such Policyowners and to determine what action,
if any, should be taken  in response thereto. If  the Trustees were to  conclude
that  separate funds should be established  for variable annuity, group annuity,
and variable  premium  life  separate  accounts, Allmerica  Life  will  pay  the
attendant expenses.
    
 
    The  Trust redeems  shares of  each Fund  at their  net asset  value as next
computed after receipt of the request  for redemption. The redemption price  may
be  more or less than the shareholder's cost.  No fee is charged by the Trust on
redemption. The group contracts  funded through the  Separate Accounts are  sold
subject  to  certain fees  and charges  which may  include sales  and redemption
charges, described  in the  prospectus or  offering circular  for such  Separate
Account.
 
    Redemption  payments will  be paid  within seven  days after  receipt of the
written request therefor by the Trust,  except that the right of redemption  may
be  suspended or  payments postponed  whenever permitted  by applicable  law and
regulations.
 
                         HOW IS PERFORMANCE DETERMINED?
 
    The Funds' performance may  be quoted in  advertising. A Fund's  performance
may be compared to the performance of other investments or relevant indices. All
performance  information is based  on historical results and  is not intended to
indicate future performance.
 
    A Fund's  "yield"  is  calculated  by dividing  the  Fund's  annualized  net
investment income per share during a recent 30-day period by the net asset value
per share on the last day of that period.
 
                                       9
<PAGE>
    Total  returns are based on the overall dollar or percentage change in value
of a hypothetical investment in a  Fund assuming all dividends and capital  gain
distributions  are  reinvested.  Cumulative  total  return  reflects  the Fund's
performance over a stated period of  time. Average annual total return  reflects
the  hypothetical annually compounded  return that would  have produced the same
cumulative return if the  Fund's performance had been  constant over the  entire
period.  Because average  annual returns  tend to  smooth out  variations in the
Fund's return, they are not the same as actual year-by-year results.
 
    YIELDS AND  TOTAL  RETURNS  QUOTED  FOR THE  FUNDS  INCLUDE  THE  EFFECT  OF
DEDUCTING  THE  FUNDS'  EXPENSES,  BUT  MAY  NOT  INCLUDE  CHARGES  AND EXPENSES
ATTRIBUTABLE TO A PARTICULAR INSURANCE PRODUCT. SINCE SHARES OF THE FUNDS CAN BE
PURCHASED ONLY THROUGH A GROUP ANNUITY, YOU SHOULD CAREFULLY REVIEW THE OFFERING
CIRCULAR FOR  THE SEPARATE  ACCOUNTS  FOR INFORMATION  ON RELEVANT  CHARGES  AND
EXPENSES.  INCLUDING THESE  CHARGES IN  THE QUOTATIONS  OF THE  FUNDS' YIELD AND
TOTAL RETURN  WOULD  HAVE  THE EFFECT  OF  DECREASING  PERFORMANCE.  PERFORMANCE
INFORMATION  FOR THE FUNDS MUST ALWAYS BE  ACCOMPANIED BY, AND BE REVIEWED WITH,
PERFORMANCE INFORMATION FOR THE SEPARATE ACCOUNTS WHICH INVEST IN THE FUNDS.
 
                  ORGANIZATION AND CAPITALIZATION OF THE TRUST
 
    The Trust was established as a  Massachusetts business trust under the  laws
of Massachusetts by an Agreement and Declaration of Trust dated October 11, 1984
(the  "Trust Declaration"). A copy of the  Trust Declaration is on file with the
Secretary of the Commonwealth of Massachusetts.
 
   
    The Trust  has  an  unlimited  authorized number  of  shares  of  beneficial
interest which may be divided into an unlimited number of series of such shares,
and  which  are  presently divided  into  twelve  series of  shares,  one series
underlying each  Fund.  The  two  Funds described  in  this  Prospectus  may  be
purchased  by the Separate Accounts established  by First Allmerica. The Trust's
shares are  entitled  to  one  vote per  share  (with  proportional  voting  for
fractional  shares). The rights  accompanying Fund shares  are legally vested in
the Separate Accounts. As a matter of policy, however, holders of group  annuity
contracts  funded through the  Separate Accounts have the  right to instruct the
Separate Accounts as to voting Fund shares on all matters to be voted on by Fund
shareholders. Voting rights  of the  participants in the  Separate Accounts  are
more  fully set forth in  the prospectus or offering  circular relating to those
Accounts. See "Organization  of the  Trust" in  the SAI  for a  definition of  a
"majority vote" of shareholders.
    
 
    The  Trust  is not  required to  hold annual  meetings of  shareholders. The
Trustees or shareholders holding at least 10% of the outstanding shares may call
special meetings of shareholders.
 
   
FUND RECORDKEEPING AGENT
    
 
   
    First Data, a wholly-owned subsidiary of First Data Corporation,  calculates
net  asset value  per share  and maintains  general accounting  records for each
Fund. First Data is entitled to  receive an annual Fund recordkeeping fee  based
on Fund assets and certain out-of-pocket expenses.
    
 
CUSTODIAN
 
   
    Bankers  Trust Company, 130 Liberty Street, New York, New York 10006, is the
Custodian of the investment securities and other assets of the Trust.
    
 
                            INVESTMENT RESTRICTIONS
 
    The following is a description of certain investment restrictions which  are
fundamental  and may not be  changed with respect to  a Fund without shareholder
approval. For a description of certain other investment restrictions,  reference
should be made to the SAI.
 
        1.   No Fund will concentrate  its investments in particular industries,
    including debt obligations of foreign governments, but a Fund may invest  up
    to  25%  of the  value of  its total  assets in  a particular  industry. The
    restriction  does  not  apply  to  investments  in  obligations  issued   or
    guaranteed   by   the   United   States   of   America,   its   agencies  or
    instrumentalities.
 
                                       10
<PAGE>
        2.  As to 75% of the value of its total assets, no Fund will invest more
    than 5% of the value of its total assets in the securities of any one issuer
    (other than securities issued by or  guaranteed as to principal or  interest
    by the United States Government or any agency or instrumentality thereof) or
    acquire  more than 10% of the voting securities of any issuer. The remaining
    25% of  assets may  be invested  in the  securities of  one or  more  issuer
    without regard to such limitations.
 
   
    These limitations apply as of the time of purchase. If through market action
the percentage limitations are exceeded, the Fund will not be required to reduce
the amount of its holding in such investments.
    
 
                   CERTAIN INVESTMENT STRATEGIES AND POLICIES
 
REPURCHASE AGREEMENTS (APPLICABLE TO BOTH FUNDS)
 
    Each Fund may invest in repurchase agreements, under which the Fund acquires
ownership  of a security (ordinarily U.S.  Government Securities) but the seller
agrees, at the time of sale, to purchase the security at a mutually agreed  upon
time  and price. Should any seller of  a repurchase agreement fail to repurchase
the underlying security, or should any seller become insolvent or involved in  a
bankruptcy  proceeding,  a  Fund  could  incur  disposition  costs  and  losses.
Repurchase agreements maturing in  more than seven days  are subject to the  15%
limit on illiquid securities.
 
"WHEN-ISSUED" SECURITIES (APPLICABLE TO BOTH FUNDS)
 
    Each  Fund  may purchase  securities on  a  when-issued or  delayed delivery
basis. Delivery  and  payment  normally take  place  15  to 45  days  after  the
commitment  to purchase.  No income accrues  on when-issued  securities prior to
delivery. Purchase  of  when-issued securities  involves  the risk  that  yields
available  in the market when delivery occurs may be higher than those available
when the when-issued order is placed resulting in a decline in the market  value
of  the  security. There  is also  the  risk that  under some  circumstances the
purchase of when-issued securities may act to leverage the Fund.
 
LENDING OF SECURITIES (APPLICABLE TO BOTH FUNDS)
 
   
    For the purpose of realizing additional income, the Funds may lend portfolio
securities to broker-dealers  or financial  institutions amounting  to not  more
than 30% of their respective total assets taken at current value. While any such
loan  is  outstanding, a  Fund will  continue  to receive  amounts equal  to the
interest or dividends paid by the issuer on the securities, as well as  interest
(less  any  rebates  to  be paid  to  the  borrower) on  the  investment  of the
collateral or a fee  from the borrower.  Each Fund will have  the right to  call
each  loan  and obtain  the  securities. Lending  portfolio  securities involves
certain risks, including possible delays  in receiving additional collateral  or
in  the recovery of the securities or  possible loss of rights in the collateral
should the borrower  fail financially.  Loans will  be made  in accordance  with
guidelines established by the Board of Trustees.
    
 
FOREIGN SECURITIES (APPLICABLE TO BOTH FUNDS)
 
    Investments  in  foreign  markets involve  substantial  risks  not typically
associated with investing in the U.  S. which should be carefully considered  by
the  investor.  Such  risks  may  include  political  and  economic instability,
differing accounting and financial reporting standards, higher commission  rates
on  foreign portfolio  transactions, less  readily available  public information
regarding issuers,  potential  adverse  changes  in  tax  and  exchange  control
regulations  and the  potential for  restrictions on  the flow  cf international
capital. Foreign  securities  also  involve  currency  risks.  Accordingly,  the
relative  strength  of  the  U.S.  dollar may  be  an  important  factor  in the
performance of  that  Fund, depending  on  the  extent of  such  Fund's  foreign
investments.  Some  foreign  securities exchanges  may  not be  as  developed or
efficient as  those in  the U.S.  and securities  traded on  foreign  securities
exchanges  are generally subject to greater  price volatility. There is also the
possibility of adverse  changes in investment  or exchange control  regulations,
expropriation  or confiscatory taxation and limitations  on the removal of funds
or other assets. Investments in emerging countries involve exposure to  economic
 
                                       11
<PAGE>
structures  that are generally less diverse and mature than in the U. S., and to
political systems which may be less  stable. In addition, securities of  issuers
located  in emerging countries may have limited marketability and may be subject
to more abrupt or erratic price fluctuations.
 
    Each Fund may buy  or sell foreign currencies  and foreign currency  forward
contracts,  options on foreign currencies and foreign currency futures contracts
and options thereon. Although such instruments  may reduce the risk of loss  due
to  a decline in  the value of  the currency that  is sold, they  also limit any
possible gain which might result should the value of the currency increase. Such
instruments will  be used  primarily to  protect a  Fund from  adverse  currency
movements,  however,  they  also  involve  the  risk  that  anticipated currency
movements will not be  accurately predicted, thus  adversely affecting a  Fund's
total return. See "Options and Futures Transactions."
 
    The  Funds' investments may include ADRs. For many foreign securities, there
are U.S.  dollar-denominated ADRs  which  are traded  in  the United  States  on
exchanges or over the counter. ADRs represent the right to receive securities of
foreign issuers deposited in a domestic bank or a correspondent bank. An ADR may
be  sponsored by  the issuer of  the underlying  foreign security, or  it may be
issued in unsponsored form. The holder of  a sponsored ADR is likely to  receive
more  frequent and extensive financial  disclosure concerning the foreign issuer
than the holder of an unsponsored ADR and will generally bear lower  transaction
charges.  The  Funds will  invest in  both sponsored  and unsponsored  ADRs. The
Select International Equity Fund also may  utilize EDRs, which are designed  for
use in European securities markets and also may invest in GDRs.
 
OPTIONS AND FUTURES TRANSACTIONS (APPLICABLE TO BOTH FUNDS)
 
    Through  the writing and purchase of put and call options on its securities,
financial indices and foreign  currencies and the purchase  and sale of  futures
contracts  and related options with respect  to securities and financial indices
in which  it  may  invest,  each  Fund  may  at  times  seek  to  hedge  against
fluctuations  in net asset value.  Each Fund's ability to  engage in options and
futures strategies will  depend on the  availability of liquid  markets in  such
instruments. It is impossible to predict the amount of trading interest that may
exist  in various types of options or  futures contracts. Therefore, there is no
assurance that a Fund will be able to utilize these instruments effectively  for
the purposes stated above.
 
    Risks  inherent in the use of futures and options ("derivative instruments")
include (1) the risk that interest rates, securities prices and currency markets
will not move in the  directions anticipated; (2) imperfect correlation  between
the  price  of  derivative  instruments  and  movements  in  the  prices  of the
securities, interest rates or currencies being hedged; (3) the fact that  skills
needed  to  use  these strategies  are  different  from those  needed  to select
portfolio securities; (4) the possible absence of a liquid secondary market  for
any  particular  instrument at  any time;  and  (5) the  possible need  to defer
closing out certain hedged positions to avoid adverse tax consequences.
 
    The Funds will purchase futures and  options only on exchanges or boards  of
trade  when there appears to be an active  secondary market, but there can be no
assurance that a liquid secondary market  will exist for any futures or  options
at any particular time.
 
    In  connection with transactions  in futures and  related options, the Funds
will be  required  to deposit  as  "initial margin"  an  amount of  cash  and/or
securities.  Thereafter, subsequent payments are made  to and from the broker to
reflect changes in the value of the futures contract.
 
    A more  detailed  explanation  of futures,  options,  and  other  derivative
instruments, and the risks associated with them, is included in the SAI.
 
RESTRICTED SECURITIES (APPLICABLE TO BOTH FUNDS)
 
    The Funds may purchase fixed-income securities that are not registered under
the  Securities Act of  1933 ("1933 Act") ("restricted  securities"), but can be
offered and sold to "qualified institutional buyers" under Rule 144A of the 1933
Act. However,  each  Fund  will not  invest  more  than 15%  of  its  assets  in
restricted  securities (as  defined in  its investment  restrictions) unless the
Funds' Board of
 
                                       12
<PAGE>
Trustees determines, based upon a continuing  review of the trading markets  for
the  specific restricted security,  that such restricted  securities are liquid.
The Board of Trustees  has adopted guidelines and  delegated to the Manager  the
daily function of determining and monitoring liquidity of restricted securities.
The   Board,  however,  will  retain  sufficient  oversight  and  be  ultimately
responsible for the  determinations. Since it  is not possible  to predict  with
assurance  exactly how  this market for  restricted securities  sold and offered
under Rule  144A will  develop,  the Board  will  carefully monitor  the  Funds'
investments  in securities, focusing on such important factors, among others, as
valuation, liquidity and availability  of information. This investment  practice
could have the effect of increasing the level of illiquidity in the Funds to the
extent  that qualified  institutional buyers become  for a  time uninterested in
purchasing these restricted securities. As a result, the Funds might not be able
to sell these securities when their Sub-Adviser  wishes to do so, or might  have
to  sell them at less  than fair value. In  addition, market quotations are less
readily available.  Therefore judgment  may  at times  play  a greater  role  in
valuing these securities than in the case of unrestricted securities.
 
INVESTMENTS IN MONEY MARKET SECURITIES (APPLICABLE TO BOTH FUNDS)
 
    Each  Fund may hold at least a portion  of its assets in cash equivalents or
money market instruments. There is  always the risk that  the issuer of a  money
market instrument may be unable to make payment upon maturity.
 
FOREIGN CURRENCY HEDGING TECHNIQUES AND INVESTMENT PRACTICES (APPLICABLE TO THE
SELECT INTERNATIONAL EQUITY FUND)
 
    The  Select International Equity Fund may employ certain strategies in order
to manage exchange rate risks.  For example, the Fund may  hedge some or all  of
its investments denominated in a foreign currency against a decline in the value
of  that  currency. The  Fund  may enter  into  contracts to  sell  that foreign
currency for  U.S.  dollars  (not  exceeding the  value  of  the  Fund's  assets
denominated  in  that  currency)  or  by  participating  in  options  or futures
contracts with respect to such currency ("position hedge"). The Fund also  could
hedge  that position by selling a second  currency, which is expected to perform
similarly to the currency  in which portfolio  investments are denominated,  for
U.S. dollars ("proxy hedge"). The Fund also may enter into a forward contract to
sell  the currency in  which the security  is denominated for  a second currency
that is  expected  to  perform  better  relative  to  the  U.S.  dollar  if  its
Sub-Adviser  believes  there  is  a  reasonable  degree  of  correlation between
movements in the two currencies  ("cross-hedge"). As an operational policy,  the
Fund  will  not  commit more  than  10% of  its  assets to  the  consummation of
cross-hedge contracts and will either  cover currency hedging transactions  with
liquid  portfolio securities denominated in the applicable currency or segregate
high-grade, liquid assets in the amount  of such commitments. In addition,  when
the Fund anticipates purchasing securities denominated in a particular currency,
the Fund may enter into a forward contract to purchase such currency in exchange
for the dollar or another currency ("anticipatory hedge").
 
    These  strategies minimize  the effect of  currency appreciation  as well as
depreciation, but do not  protect against a decline  in the underlying value  of
the  hedged security. In  addition, such strategies may  reduce or eliminate the
opportunity to profit from increases in  the value of the original currency  and
may  adversely impact the Fund's performance  if its Sub-Adviser's projection of
future exchange rates is inaccurate.

Poor's Ratings  Service,  a  division of  McGraw-Hill  Companies,  Inc.  ("S&P")
commercial paper and bond ratings:
    
 
COMMERCIAL PAPER RATINGS
 
    MOODY'S  EMPLOYS THREE DESIGNATIONS,  ALL JUDGED TO  BE INVESTMENT GRADE, TO
INDICATE THE  RELATIVE REPAYMENT  CAPACITY  OF RATED  ISSUERS. THE  TWO  HIGHEST
DESIGNATIONS ARE AS FOLLOWS:
 
        Issuers  rated  Prime- 1  (or  related supporting  institutions)  have a
    superior  capacity  for  repayment  of  short-term  promissory  obligations.
    Prime-l  repayment  capacity will  normally  be evidenced  by  the following
    characteristics:
 
       -- Leading market positions in well-established industries.
 
       -- High rates of return on funds employed
 
       -- Conservative capitalization structures with moderate reliance on  debt
          and ample asset protection
 
       -- Broad margins in earnings coverage of fixed financial charges and high
          internal cash generation.
 
       -- Well-established  access to a  range of financial  markets and assured
          sources of alternate liquidity.
 
    Issuers rated Prime-2  (or related  supporting institutions)  have a  strong
capacity  for repayment of short-term promissory obligations. This normally will
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 alternate liquidity is maintained.
 
   
    S&P COMMERCIAL PAPER  RATINGS ARE  GRADED INTO  SEVERAL CATEGORIES,  RANGING
FROM  "A-1" FOR THE HIGHEST  QUALITY OBLIGATIONS TO "D"  FOR THE LOWEST. THE TWO
HIGHEST RATING CATEGORIES ARE DESCRIBED AS FOLLOWS:
    
 
   
        A-1 --  This  highest  category  indicates that  the  degree  of  safety
    regarding  timely  payment is  strong.  Those issues  determined  to possess
    extremely strong safety  characteristics are  denoted with a  plus (+)  sign
    designation.
    
 
   
        A-2  -- Capacity for  timely payment on issues  with this designation is
    satisfactory. However, the relative degree of  safety is not as high as  for
    issues designated A-1.
    
 
MUNICIPAL OBLIGATIONS
 
    Moody's  ratings for  state and  municipal and  other short-term obligations
will be  designated Moody's  Investment Grade  ("MIG"). This  distinction is  in
recognition  of  the differences  between short-term  credit risk  and long-term
risk.  Factors  affecting  the  liquidity  of  the  borrower  are  uppermost  in
importance   in  short-term  borrowing,  while  various  factors  of  the  first
importance in long-term borrowing risk are of lesser importance in the long run.
Symbols used will be as following
 
   
        MIG-1 -- This designation denotes best quality. There is present  strong
    protection   by  established  cash  flows,  superior  liquidity  support  or
    demonstrated broad-based access to the market for refinancing.
    
 
   
        MIG-2 -- This  designation denotes high  quality. Margins of  protection
    are ample although not so large as in the preceding group.
    
 
    A  short-term  rating may  also  be assigned  on  an issue  having  a demand
feature. Such ratings will be designated as VMIG to reflect such characteristics
as payment upon  periodic demand rather  than fixed maturity  dates and  payment
relying   on  external  liquidity.  Additionally,   investors  should  be  alert
 
                                       14
<PAGE>
   
to the fact that the source of payment may be limited to the external  liquidity
with  no or limited legal recourse to the  issuer in the event the demand is not
met. VMIG- 1 and VMIG-2 ratings carry  the same definitions as MIG-1 and  MIG-2,
respectively.
    
 
DESCRIPTION OF MOODY'S BOND RATINGS
 
   
    AAA  -- Bonds that are rated Aaa are  judged to be of the best quality. They
carry the smallest degree  of investment risk and  are generally referred to  as
"gilt  edge. " Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to  impair
the fundamentally strong position of such issues.
    
 
   
    AA  -- Bonds  that are  rated Aa  are judged  to be  of high  quality by all
standards. Together with the Aaa group,  they comprise what are generally  known
as high-grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements  may be  of greater  amplitude or there  may be  other elements present
which make the long-term risks appear somewhat larger than in Aaa securities.
    
 
   
    A -- Bonds that are rated A possess many favorable investment attributes and
are to be considered as upper medium grade obligations. Factors giving  security
to  principal and interest are considered  adequate, but elements may be present
that suggest a susceptibility to impairment some time in the future.
    
 
   
    BAA -- Bonds that are rated Baa are considered as medium grade  obligations,
i.e.,  they are neither  highly protected nor  poorly secured. Interest payments
and principal security appear  adequate for the  present but certain  protective
elements  may be lacking or may  be characteristically unreliable over any great
length of time. Such  bonds lack outstanding  investment characteristics and  in
fact have speculative characteristics as well.
    
 
   
    Those  bonds within Aa,  A and Baa categories  that Moody's believes possess
the strongest credit attributes  within those categories  are designated by  the
symbols Aa1, A1 and Baa1.
    
 
   
DESCRIPTION OF S&P'S DEBT RATINGS
    
 
   
    AAA  -- Debt rated AAA  has the highest rating  assigned by S&P. Capacity to
pay interest and repay principal is extremely strong.
    
 
   
    AA -- Debt rated  AA has a  very strong capacity to  pay interest and  repay
principal and differs from AAA issues only in a 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. Where as 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.
    
 
    PLUS (+) OR (-): The ratings from AA to BBB may be modified by the  addition
of a plus or minus sign to show relative standing within the major categories.

                              GENERAL INFORMATION
 
   
    Allmerica  Investment Trust (the "Trust") is an open-end, diversified series
investment company designed  to provide  the underlying  investment vehicle  for
various  separate investment  accounts established by  First Allmerica Financial
Life Insurance Company ("First Allmerica") or Allmerica Financial Life Insurance
and Annuity Company ("Allmerica Life"),  an indirect wholly-owned subsidiary  of
First  Allmerica. Shares of the Trust are  not offered to the general public but
solely to such separate investment accounts ("Separate Accounts").
    
 
    The Trust is a Massachusetts business trust established on October 11, 1984.
It currently is comprised of  twelve different portfolios: Select  International
Equity  Fund, Select Aggressive  Growth Fund, Select  Capital Appreciation Fund,
Small Cap Value Fund, Select Growth Fund, Growth Fund, Select Growth and  Income
Fund,  Equity  Index Fund,  Investment Grade  Income  Fund, Select  Income Fund,
Government Bond Fund,  and Money Market  Fund (each  a "Fund"). Not  all of  the
Funds  are offered to each Separate  Account. The Trustees may create additional
funds in the future.
 
                       INVESTMENT OBJECTIVES AND POLICIES
 
    SELECT INTERNATIONAL  EQUITY  FUND  seeks  maximum  long-term  total  return
(capital  appreciation and  income) primarily by  investing in  common stocks of
established non-U.S. companies.
 
    SELECT AGGRESSIVE GROWTH  FUND seeks above-average  capital appreciation  by
investing  primarily in  common stocks of  companies which are  believed to have
significant potential for capital appreciation.
 
   
    SELECT CAPITAL  APPRECIATION FUND  seeks long-term  growth of  capital in  a
manner consistent with the preservation of capital. Realization of income is not
a  significant investment  consideration and any  income realized  on the Fund's
investments will be incidental to its primary objective.
    
 
    SMALL CAP  VALUE  FUND  seeks  long-term  growth  of  capital  by  investing
principally   in  a   diversified  portfolio   of  common   stocks  of  smaller,
faster-growing companies whose securities at the time of purchase are considered
by the sub-adviser to  be attractively valued in  the smaller company sector  of
the market.
 
    SELECT GROWTH FUND seeks to achieve long-term growth of capital by investing
in a diversified portfolio consisting primarily of common stocks selected on the
basis of their long-term growth potential.
 
    GROWTH FUND seeks to achieve long-term growth of capital through investments
primarily  in common stocks  and securities convertible  into common stocks that
are believed to represent  significant underlying value  in relation to  current
market  prices. Realization  of current  income, if  any, is  incidental to this
objective.
 
    SELECT GROWTH AND  INCOME FUND seeks  a combination of  long-term growth  of
capital  and current income.  The Fund will  invest primarily in dividend-paying
common stocks and securities convertible into common stocks.
 
    EQUITY INDEX FUND seeks to achieve investment results that correspond to the
aggregate price and yield  performance of a  representative selection of  common
stocks that are publicly traded in the United States.
 
    INVESTMENT  GRADE INCOME FUND seeks  as high a level  of total return, which
includes capital appreciation as well as  income, as is consistent with  prudent
investment management.
 
    SELECT  INCOME FUND  seeks a  high level  of current  income. The  Fund will
invest primarily in investment grade, fixed-income securities.
 
    GOVERNMENT  BOND  FUND  seeks  high  income,  preservation  of  capital  and
maintenance  of  liquidity  primarily through  investments  in  debt instruments
issued or guaranteed by the U.S. Government or
 
                                       3
<PAGE>
its agencies or instrumentalities ("U.S. Government securities") and in  related
options,  futures and repurchase  agreements. Under normal  conditions, at least
80% of the Fund's assets will be invested in U.S. Government securities.
 
    MONEY MARKET FUND  seeks to  obtain maximum current  income consistent  with
preservation of capital and liquidity.
 
    A  Fund's investment objective and its  policies listed above and identified
in the Prospectus as fundamental  may not be changed  without the approval of  a
majority  in interest of  the shareholders of that  Fund. Except where otherwise
noted, other investment  policies and  techniques of  the Funds  are not  deemed
fundamental  and may be  changed by the  Trustees. There is  no assurance that a
Fund's investment objective will be realized.
 
    For a description  of the  types of investments  each Fund  may acquire  and
certain  investment techniques  it may  utilize, see  "Investment Objectives and
Policies" in  the  appropriate  Prospectus  for  the  underlying  Funds  of  the
applicable Separate Account.
 
MORE INFORMATION ABOUT THE EQUITY INDEX FUND
 
    The  Equity Index Fund  will attempt to replicate  the investment results of
the Standard &  Poor's 500  Composite Stock Price  Index (the  "S&P 500")  while
minimizing  transactional costs  and other expenses.  Stocks in the  S&P 500 are
ranked in accordance with their statistical weighing from highest to lowest. The
method used to select investments for  the Equity Index Fund involves  investing
in  common stocks in approximately  the order of their  weighing in the S&P 500,
beginning with those having the highest weighing. In addition, the Equity  Index
Fund  purchases stocks with smaller weighing in order to represent other sectors
of the S&P 500 for diversification purposes.
 
    The Equity Index Fund will invest only in those stocks, and in such amounts,
as its investment  adviser determines  to be  necessary or  appropriate for  the
Equity  Index Fund to approximate  the S&P 500. As the  size of the Equity Index
Fund increases, the  Equity Index Fund  may purchase a  larger number of  stocks
included  in the  S&P 500,  and the  percentage of  its assets  invested in most
stocks included in the S&P 500 will approach the percentage that each such stock
represents in the S&P  500. However, there  is no minimum  or maximum number  of
stocks  included in  the S&P 500  which the  Equity Index Fund  will hold. Under
normal circumstances it is expected that the Equity Index Fund will hold between
300 and 475 different stocks included in the S&P 500. The Equity Index Fund  may
compensate  for the omission of a stock that  is included in the S&P 500, or for
purchasing stocks in other than the  same proportions that they are  represented
in  the S&P 500, by purchasing stocks which are believed to have characteristics
which correspond to those of the omitted stocks.
 
    The Equity Index Fund may invest in short-term debt securities, to  maintain
liquidity or pending investment in stocks. Such investments will not be made for
defensive  purposes or in anticipation of a  general decline in the market price
of stocks in which the Equity Index Fund invests; investors in the Equity  Index
Fund  bear the risk of  general declines in the  stock markets. The Equity Index
Fund may also take advantage of tender offers, resulting in higher returns  than
are  reflected in the performance of the  S&P 500. In addition, the Equity Index
Fund may hold warrants,  preferred stocks, and debt  securities, whether or  not
convertible  into common stock or with rights  attached, if acquired as a result
of in-kind  dividend distributions,  mergers, acquisitions,  or other  corporate
activity  involving  the  common stocks  held  by  the Equity  Index  Fund. Such
investment transactions  and  securities  holdings may  result  in  positive  or
negative tracking error.
 
    Although it does not presently intend to do so the Equity Index Fund at some
time  in the future may purchase or sell futures contracts on stocks indexes for
hedging purposes  and  in order  to  achieve  a fully  invested  position  while
maintaining   sufficient  liquidity  to  meet   possible  net  redemptions.  The
effectiveness of a strategy of investing in stock index futures contracts  would
depend upon the continued availability of futures contracts based on the S&P 500
or  which tend to move together with stocks  included in the S&P 500. The Equity
Index Fund  would  not  enter  into  futures  contracts  on  stock  indexes  for
speculative purposes.

MORE INFORMATION ABOUT THE GOVERNMENT BOND FUND
 
    The  Government Bond Fund will invest in obligations issued or guaranteed by
the U.S. Government, its agencies and instrumentalities, and options and futures
thereon, as described in the prospectus. The securities in which the  Government
Bond Fund may invest include, but are not limited to, U.S. Treasury bills, notes
and  bonds,  and  obligations  of the  following:  Banks  for  Cooperatives, the
Commodity Credit Corporation, the Federal Deposit Insurance Corporation, Federal
Farm Credit  Banks,  the  Federal  Financing  Bank,  Federal  National  Mortgage
Association,   the   General  Insurance   Fund,  Government   National  Mortgage
Association, Government  Services  Administration  (GSA  Public  Building  Trust
Participation Certificates), the Production Credit Association, the Student Loan
Marketing  Association,  the Tennessee  Valley  Authority, and  the  U.S. Postal
Service.
 
    The Government Bond Fund may invest in mortgage-backed securities (including
pass-through  securities  and  participation  certificates)  of  the  Government
National  Mortgage Association  ("Ginnie Mae"),  the Federal  Home Loan Mortgage
Corporation ("Freddie  Mac"),  and  the Federal  National  Mortgage  Association
("Fannie Mae").
 
    Ginnie  Mae  certificates are  mortgage-backed securities  representing part
ownership of a pool of mortgage loans. The mortgage loans are issued by  lenders
such  as mortgage bankers,  commercial banks and  savings and loan associations,
and are either insured  by the Federal Housing  Administration or guaranteed  by
the  Veterans  Administration.  After  approval  of  the  pool  by  Ginnie  Mae,
certificates in the pool  are offered to investors  by securities dealers.  Once
the  pool has been  approved by Ginnie  Mae, the timely  payment of interest and
principal on the certificates is guaranteed by the full faith and credit of  the
U.S.  Government. The certificates  are "pass through"  securities because a pro
rata share of regular  interest and principal payments,  as well as  unscheduled
early  prepayments, on the underlying mortgage pool is passed through monthly to
the Fund.
 
    Freddie Mac, a corporate instrumentality  of the U.S. Government created  by
Congress  to  increase  the  availability  of  mortgage  credit  for residential
housing, issues participation certificates  representing undivided interests  in
Freddie  Mac's  mortgage  portfolio.  While Freddie  Mac  guarantees  the timely
payment  of  interest  and   ultimate  collection  of   the  principal  of   its
participation certificates, the participation certificates are not backed by the
full faith and credit of the U.S. Government. The "pass-through" characteristics
of   Freddie  Mac   participation  certificates   are  similar   to  Ginnie  Mae
certificates, but Freddie Mac certificates  differ from Ginnie Mae  certificates
in  that Freddie Mac mortgages  are primarily conventional residential mortgages
rather  than   mortgages  issued   or  guaranteed   by  a   federal  agency   or
instrumentality.
 
    Fannie   Mae  is  a   federally  chartered  corporation   owned  by  private
stockholders. Fannie Mae  purchases both conventional  and federally insured  or
guaranteed  residential mortgages from  various entities, and  packages pools of
such mortgages in the form  of pass-through certificates. Fannie Mae  guarantees
the timely payment of principal and interest. Fannie Mae is authorized to borrow
from  the U.S. Treasury  to meet its  obligations, but the  certificates are not
backed by the full faith and credit of the U.S. Government.
 
    The effective maturity  of a  mortgage-backed security may  be shortened  by
unscheduled  or  early  payments of  principal  and interest  on  the underlying
mortgages, which may affect their effective yield. When the Government Bond Fund
receives the  monthly "pass-through"  payments  (which may  include  unscheduled
prepayments  of principal) it may be able to invest the payments only at a lower
rate of interest. During  periods of declining  interest rates, such  securities
therefore  may be less effective as a means of "locking in" attractive long-term
interest rates and may  have less potential  for appreciation than  conventional
bonds with comparable stated maturities.

                            INVESTMENT RESTRICTIONS
 
    The following is a description of certain restrictions on investments of the
Funds  (in  addition  to  those described  in  the  Prospectus).  The investment
restrictions numbered 1 through 7 are fundamental and may not be changed without
the approval of a  majority in interest  of the shareholders  of that Fund.  The
other  investment restrictions are not deemed  fundamental and may be changed by
the Trustees. The following investment  restrictions apply to each Fund,  except
as noted:
 
    1.   The Fund will not issue "senior securities" as defined in Section 18(g)
       of the Investment Company Act of 1940.
 
    2.  The Fund will not borrow money, except for temporary purposes where  the
       aggregate  amount borrowed does not exceed 5%  of the value of the Fund's
       total assets at the time such borrowing is made. In general, a  borrowing
       shall  be regarded as being for temporary purposes if it is repaid within
       60 days and is not extended or renewed.
 
    3.  The Fund will  not act as an underwriter  except to the extent that,  in
       connection with the disposition of portfolio securities, it may be deemed
       to  be an  underwriter under  certain federal  securities laws.  The Fund
       (except for  the  Select  International Equity  Fund,  Select  Aggressive
       Growth Fund, Select Capital Appreciation Fund, Select Growth Fund, Select
       Growth  and  Income  Fund and  Select  Income  Fund) will  not  invest in
       securities  which  are  restricted   as  to  disposition  under   federal
       securities laws.
 
    4.   The Fund will not buy or  sell real estate or interests in real estate,
       although it may  purchase and sell  (a) securities which  are secured  by
       real  estate and (b) securities of companies which invest or deal in real
       estate.
 
    5.  The  Fund will not  engage in the  purchase and sale  of commodities  or
       commodity contracts, except financial futures (including securities index
       futures)  contracts and  related options  and in  the case  of the Select
       Capital Appreciation Fund,  futures contracts on  foreign currencies  and
       related options. The Money Market Fund will not engage in transactions in
       financial futures or related options.
 
    6.    The Fund  may  make loans  to  other persons  only  through repurchase
       agreements and securities  lending. For purposes  of this paragraph,  the
       purchase  of an issue of publicly  distributed bonds, debentures or other
       debt securities, whether or not the  purchase was made upon the  original
       issue  of the securities, is not to be considered the making of a loan by
       the Fund.
 
    7.  The  Fund will not  purchase securities  on margin but  may obtain  such
       short-term  credits as are necessary  for the clearance transactions, and
       (except for the Money Market Fund) may make margin payments in connection
       with financial futures  (including securities  index futures)  contracts,
       and  options  on such  future contracts  and  in the  case of  the Select
       Capital Appreciation Fund,  futures contracts on  foreign currencies  and
       related  options. The Fund will  not participate on a  joint or joint and
       several basis in any trading account in securities or effect a short sale
       of securities.
 
    8.  The  Fund does  not intend  to invest in  companies for  the purpose  of
       exercising control or management.
 
    9.   The Fund may  invest in the securities of  one or more other investment
       companies. No such investment  shall be made if  as a result thereof  the
       Fund  would own more than 3% of the total outstanding voting stock of any
       one investment company,  or more than  5% of the  Fund's assets would  be
       invested  in any one investment  company, or more than  a total of 10% of
       the Fund's assets  would be  invested in  investment company  securities.
       Purchase of such securities will be made only in the open market where no
       commission  or profit to  a sponsor or dealer  results from such purchase
       other than the  customary broker's  commission or  as part  of a  merger,
       consolidation, or plan of reorganization.
 
                                       6
<PAGE>
   
    10.  The  Fund intends  to  purchase securities  for  investment and  not to
       purchase and  sell them  for  trading purposes,  except that  the  Select
       Capital  Appreciation Fund  and the  Government Bond  Fund may  engage in
       short term trading of U.S. Government securities.
    
 
                             INVESTMENT TECHNIQUES
 
    In managing its  portfolios of investments,  the Trust may  make use of  the
following investment techniques:
 
SECURITIES LENDING
 
   
    Each  Fund may loan  its portfolio securities  to broker-dealers pursuant to
agreements requiring  that  the loans  be  continuously secured  by  cash,  cash
equivalents  or securities issued or guaranteed  by the United States government
or its  agencies,  or  any  combination  of  cash,  cash  equivalents  and  such
securities  as collateral equal at all times to at least the market value of the
securities loaned. Such loans are not made if, as a result, the aggregate of all
outstanding loans would exceed 30% of the value of the Fund's total assets taken
at current value.  The Fund continues  to receive interest  or dividends on  the
securities  loaned, and simultaneously  earns interest on  the investment of the
loan collateral in U.S.  Treasury securities, certificates  of deposit or  other
high-grade,  short-term  obligations  or  interest-bearing  cash  equivalents or
receives a fee from the borrower. Although voting rights, or rights to  consent,
attendant  to securities lent pass to the  borrower, such loans may be called at
any time and may be called so that the securities may be voted by the Fund if  a
material event affecting the investment is to occur. There may be risks of delay
in  recovery of the securities  or even loss of  rights in the collateral should
the borrower of the securities fail financially. However, loans are made only to
firms deemed by the Fund's sub-adviser to be of good standing, and when, in  the
judgment  of  the  Fund's sub-adviser,  the  consideration which  can  be earned
currently from such securities loans justifies the attendant risk.
    
 
FOREIGN SECURITIES
 
    The Select International Equity Fund, Select Aggressive Growth Fund,  Select
Capital  Appreciation Fund, Select  Growth Fund, Growth  Fund, Select Growth and
Income Fund,  Equity Index  Fund and  Select Income  Fund may  purchase  foreign
securities.  The  Investment  Grade  Income  Fund  may  not  invest  in  foreign
securities other than the obligations of the Government of Canada and  political
subdivisions    thereof.   Securities    of   foreign    issuers,   particularly
non-governmental issuers, involve risks which are not ordinarily associated with
investing in domestic issuers. These risks include changes in currency  exchange
rates,  and currency exchange  control regulations. In  addition, investments in
foreign countries could be affected by other factors generally not thought to be
present  in  the  United  States,  including  the  unavailability  of  financial
information  or the  difficulty of  interpreting financial  information prepared
under foreign  accounting  standards,  less liquidity  and  more  volatility  in
foreign securities markets, the possibility of expropriation, the possibility of
heavy  taxation,  the impact  of political,  social or  diplomatic developments,
limitations on the removal of funds or  other assets of a Fund, difficulties  in
evoking  legal  process abroad  and enforcing  contractual obligations,  and the
difficulty of assessing economic trends in foreign countries.
 
FORWARD COMMITMENTS
 
   
    The Select Capital Appreciation Fund,  Select Income Fund, Investment  Grade
Income  Fund  and Government  Bond  Fund may  enter  into contracts  to purchase
securities for  a  fixed price  at  a  specified future  date  beyond  customary
settlement  time ("forward commitments"). If the Funds do so, they will maintain
cash or  high-grade  obligations  having a  value  in  an amount  at  all  times
sufficient  to meet  the purchase price.  Forward commitments involve  a risk of
loss if  the  value of  the  security to  be  purchased declines  prior  to  the
settlement   dates.  Although  the  Funds  will  generally  enter  into  forward
commitments with the intention of acquiring securities for their portfolio, they
may dispose of a  commitment prior to settlement  if their sub-adviser deems  it
appropriate  to do so. The Funds may realize short-term gains or losses upon the
sale of forward commitments. The  sub-adviser will monitor the  creditworthiness
of the parties to such forward commitments.
    
 
                                       7
<PAGE>
WHEN-ISSUED SECURITIES
 
    Each  Fund  may from  time to  time purchase  securities on  a "when-issued"
basis. Debt securities and municipal obligations are often issued on this basis.
The yield of such securities  is fixed at the time  a commitment to purchase  is
made, with actual payment and delivery of the security generally taking place 15
to  45 days later. During the  period between purchase and settlement, typically
no payment is made  by a Fund and  no interest accrues to  the Fund. The  market
value  of when-issued  securities may  be more or  less than  the purchase price
payable at settlement date.  The Fund will establish  a segregated account  with
the  Custodian in which it will maintain  cash or high-grade debt obligations at
least  equal  to  commitments   for  when-issued  securities.  Such   segregated
securities  either will mature or,  if necessary, will be  sold on or before the
settlement date.
 
REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS
 
    Each Fund may enter into repurchase agreements. Under repurchase agreements,
the Funds  may purchase  an obligation  of or  guaranteed by  the United  States
Government,  its agents or instrumentalities, with  an agreement that the seller
will repurchase the obligation at an agreed upon price and date. The  repurchase
price  reflects an  agreed-upon interest rate  which is unrelated  to the coupon
rate on the purchased  obligation. Repurchase agreements  usually are for  short
periods,  such  as  under one  week,  but may  be  as  long as  thirty  days. No
repurchase agreement will be effected if, as a result, more than 30% of a Fund's
total assets taken at current value  will be invested in repurchase  agreements.
No  more  than 15%  of a  Fund's total  assets  taken at  current value  will be
invested in repurchase  agreements extending  for more  than seven  days and  in
other securities which are not readily marketable.
 
    If  a seller defaults upon the obligation to repurchase, the Funds may incur
a loss if the value of  the purchased obligation (collateral) declines, and  may
incur disposition costs in liquidating the collateral. If bankruptcy proceedings
are  commenced with respect to a seller,  realization upon the collateral by the
Funds may be delayed or limited.
 
    Prior to  entering  into a  repurchase  agreement, the  Funds'  sub-advisers
evaluate  the creditworthiness of entities with which the Funds propose to enter
into  repurchase  agreements.  The  Trustees  have  established  guidelines  and
standards  of  review  for  the evaluation  of  creditworthiness  by  the Funds'
sub-advisers and monitor such sub-advisers'  actions with respect to  repurchase
transactions.
 
    The  Select Capital Appreciation Fund also may enter into reverse repurchase
agreements. In a reverse repurchase agreement, a Fund sells a portfolio security
to another party, such as a bank or broker-dealer, in return for cash and agrees
to repurchase the instrument at a particular price and at a future date. While a
reverse repurchase  agreement is  outstanding,  a Fund  will maintain  cash  and
appropriate  liquid  assets  in  a segregated  custodial  account  to  cover its
obligation  under  the   reverse  repurchase  agreement.   The  Select   Capital
Appreciation  Fund  will  enter  into reverse  repurchase  agreements  only with
parties that its sub-adviser deems creditworthy.
 
WRITING COVERED OPTIONS
 
   
    Each Fund other  than the Small  Cap Value  Fund and Money  Market Fund  may
write  call options  and put options  on securities  which the Fund  owns as its
sub-adviser shall determine  to be appropriate  and to the  extent permitted  by
applicable  law. A call  option gives the  purchaser of the  option the right to
buy, and  a  writer the  obligation  to sell,  the  underlying security  at  the
exercise  price at any time prior to the expiration of the option, regardless of
the market price of the security during the option period. A premium is paid  to
the writer as the consideration for undertaking the obligations under the option
contract.  The writer forgoes the opportunity to  profit from an increase in the
market price of the underlying security above the exercise price except  insofar
as the premium represents such a profit.
    
 
    As  the writer of a  call option, a Fund  receives a premium for undertaking
the obligation  to sell  the underlying  security at  a fixed  price during  the
option  period if the option is exercised. So long as the Fund remains obligated
as the writer of a call, it forgoes the opportunity to profit from increases  in
the
 
                                       8
<PAGE>
market  price of the underlying security above the exercise price of the option,
except insofar as the premium represents such a profit, and retains the risk  of
loss  should the  value of the  security decline.  The Fund also  may enter into
"closing purchase  transactions" in  order to  terminate its  obligation as  the
writer  of a  call option  prior to the  expiration of  the option.  There is no
assurance that a Fund will be able to effect such transactions at any particular
time or at any acceptable price.
 
    The writer of  a put option  is obligated to  purchase specified  securities
from  the option holder at  a specified price at  any time before the expiration
date of  the  option.  The  purpose  of writing  such  options  is  to  generate
additional  income for the Fund,  but the Fund accepts the  risk that it will be
required to  purchase the  underlying securities  at a  price in  excess of  the
securities' market value at the time of purchase.
 
    Option transactions may increase a Fund's transaction costs and may increase
the  portfolio turnover rate, depending on how  many options written by the Fund
are exercised in a particular year.
 
PURCHASING OPTIONS
 
    Each Fund other  than the Small  Cap Value  Fund and Money  Market Fund  may
purchase  put and call options to the extent permitted by applicable law. A Fund
will not purchase put or call options if after such purchase more than 5% of its
net assets, as  measured by  the aggregate  of the  premiums paid  for all  such
options  held by the  Fund, would be so  invested. A Fund would  also be able to
enter into  closing sale  transactions in  order to  realize gains  or  minimize
losses on exchange traded options purchased by the Fund.
 
    A  Fund would normally purchase call  options in anticipation of an increase
in the market value of  securities. The purchase of  a call option entitles  the
Fund,  in return  for the  premium paid, to  purchase specified  securities at a
specified price  during the  option  period. If  the  value of  such  securities
exceeded  the sum of the exercise price, the premium paid, and transaction costs
during the option period, the Fund would ordinarily realize a gain; if not,  the
Fund would realize a loss.
 
    A  Fund would normally purchase put options  in anticipation of a decline in
the  market  value  of  securities  in  its  portfolio  ("protective  puts")  or
securities  of the  type in which  it may invest.  The purchase of  a put option
would entitle the  Fund, in  exchange for the  premium paid,  to sell  specified
securities  at a specified price during the  option period. Gains or loss on the
purchase of put options would tend to be offset by countervailing changes in the
value of underlying portfolio securities. A Fund would ordinarily realize a gain
if, during the option period, the  value of the underlying securities  decreased
below  the  exercise price  sufficiently to  cover  the premium  and transaction
costs; otherwise  the Fund  would realize  a loss  on the  purchase of  the  put
option.
 
    There  is no assurance that a liquid secondary market on an options exchange
will exist  for a  particular option,  or at  a particular  time. The  hours  of
trading  for options on  options exchanges may  not conform to  the hours during
which the  underlying securities  are  traded. To  the  extent that  the  option
markets  close  before the  markets for  the underlying  securities, significant
price and rate  movements can take  place in the  underlying securities  markets
that  cannot be reflected  in the option  markets. In addition,  the purchase of
options  is  a  highly  specialized  activity  which  depends  in  part  on  the
sub-adviser's  ability to  predict future price  fluctuations and  the degree of
correlation between the options  and securities markets.  A Fund pays  brokerage
commission or spread in connection with its options transactions, as well as for
purchases and sales of the underlying securities.
 
FINANCIAL FUTURES CONTRACTS AND RELATED OPTIONS
 
    Each  Fund (other than the  Small Cap Value Fund  and Money Market Fund) may
invest in transactions in  financial futures contracts  and related options  for
hedging  purposes. In addition, the Select Capital Appreciation Fund may utilize
futures contracts on  foreign currencies  and related  options. Through  certain
hedging  activities involving such futures contracts  and related options, it is
possible to reduce the effects of fluctuations in interest rates and the  market
prices of securities which
 
                                       9
<PAGE>
have  become  increasingly  volatile in  recent  years.  Hedging is  a  means of
transferring that risk  which an investor  does not desire  to assume during  an
uncertain  interest rate or  securities market environment,  to another investor
who is willing to assume that risk.
 
    The Select Capital Appreciation  Fund may buy and  write options on  foreign
currencies  in a manner similar to that in which futures or forward contracts on
foreign currencies will be utilized. For  example, a decline in the U.S.  dollar
value  of a foreign currency in  which portfolio securities are denominated will
reduce the U.S.  dollar value of  such securities,  even if their  value in  the
foreign  currency remains constant. In order to protect against such diminutions
in the value of portfolio securities,  the Select Capital Appreciation Fund  may
buy  put options on the foreign currency. If the value of the currency declines,
such Fund will have the right to sell  such currency for a fixed amount in  U.S.
dollars  and  will  offset, in  whole  or in  part,  the adverse  effect  on its
portfolio.
 
    Conversely, when a  rise in the  U.S. dollar  value of a  currency in  which
securities  to be acquired are denominated  is projected, thereby increasing the
cost of  such securities,  the Select  Capital Appreciation  Fund may  buy  call
options  thereon. The purchase of such options could offset, at least partially,
the effects of the adverse movements in exchange rates. As in the case of  other
types  of options, however, the  benefit to such Fund  from purchases of foreign
currency options  will be  reduced by  the  amount of  the premium  and  related
transaction  costs. In addition, if  currency exchange rates do  not move in the
direction or to the extent desired,  the Select Capital Appreciation Fund  could
sustain  losses on transactions  in foreign currency  options that would require
such Fund to forgo a portion or  all of the benefits of advantageous changes  in
those rates.
 
    The  Select  Capital Appreciation  Fund also  may  write options  on foreign
currencies. For example, to hedge against a potential decline in the U.S. dollar
value of foreign currency denominated securities due to adverse fluctuations  in
exchange  rates, such Fund  could, instead of  purchasing a put  option, write a
call option on the relevant currency. If the expected decline occurs, the option
will most  likely not  be exercised  and the  diminution in  value of  portfolio
securities will be offset by the amount of the premium received.
 
    Similarly,  instead of purchasing a call option to hedge against a potential
increase in  the U.S.  dollar cost  of  securities to  be acquired,  the  Select
Capital  Appreciation Fund  could write  a put  option on  the relevant currency
which, if rates move in the manner projected, will expire unexercised and  allow
such Fund to hedge the increased cost up to the amount of the premium. As in the
case  of other  types of  options, however,  the writing  of a  foreign currency
option will constitute only a partial hedge up to the amount of the premium.  If
exchange  rates  do  not move  in  the  expected direction,  the  option  may be
exercised and such Fund would be required to buy or sell the underlying currency
at a loss  which may not  be offset by  the amount of  the premium. Through  the
writing  of options on foreign currencies,  the Select Capital Appreciation Fund
also may lose all or a portion  of the benefits which might otherwise have  been
obtained from favorable movements in exchange rates.
 
    The  Select  Capital Appreciation  Fund may  write  covered call  options on
foreign currencies. A call option written on  a foreign currency by the Fund  is
"covered"  if the Fund owns the underlying  foreign currency covered by the call
or has an absolute and immediate right to acquire that foreign currency  without
additional  cash consideration (or  for additional cash  consideration held in a
segregated account by the Fund's custodian) upon conversion or exchange of other
foreign currency held in its  portfolio. A call option  is also covered if  such
Fund has a call on the same foreign currency and in the same principal amount as
the  call written if the exercise price of the call held (i) is equal to or less
than the exercise price of the call written or (ii) is greater than the exercise
price of the call written, if the difference is maintained by such Fund in  cash
or high-grade liquid assets in a segregated account with the Fund's custodian.
 
    The  Select Capital Appreciation Fund also may write call options on foreign
currencies for cross-hedging purposes that would not be deemed to be covered.  A
call  option on a  foreign currency is  for cross-hedging purposes  if it is not
covered but is designed to provide a  hedge against a decline due to an  adverse
change  in the exchange  rate in the U.S.  dollar value of  a security that such
Fund owns or has
 
                                       10
<PAGE>
the right to  acquire and  that is denominated  in the  currency underlying  the
option.   In   such  circumstances,   the   Select  Capital   Appreciation  Fund
collateralizes the option by segregating cash or high-grade liquid assets in  an
amount  not  less than  the value  of  the underlying  foreign currency  in U.S.
dollars marked-to-market daily. The Select Capital Appreciation Fund may  invest
without limitation in foreign currency options.
 
GENERAL INFORMATION.
 
    A  futures contract  on a security  is a standardized  agreement under which
each party is entitled and obligated either to make or to accept delivery, at  a
particular  time, of securities having a specified face value and rate of return
on foreign currencies. Currently,  futures contracts are  available on debt  and
equity securities and on certain foreign currencies.
 
    Futures contracts are traded on exchanges that are licensed and regulated by
the  Commodity Futures Trading Commission  ( "CFTC" ). A  futures contract on an
individual security may be deemed to be a commodities contract. A Fund  engaging
in a futures transaction initially will be required to deposit and maintain with
its  Custodian, in the name  of its brokers, an amount  of cash or U.S. Treasury
bills equal  to a  small percentage  (generally less  than 5%)  of the  contract
amount  to guarantee  performance of  its obligations.  This amount  is known as
"initial margin." Margin in futures transactions  is different from margin in  a
securities  transaction,  in  that  financial futures  initial  margin  does not
involve the borrowing of  funds to finance  the transactions. Unlike  securities
margin,  initial  margin  in  a  futures  transaction  is  in  the  nature  of a
performance bond or good faith deposit on the contract which is returned to  the
Fund  upon  termination  of  the  financial  future,  assuming  all  contractual
obligations have  been  satisfied.  As  the price  of  the  underlying  security
fluctuates,  making the position in the financial futures more or less valuable,
subsequent payments called "maintenance margin"  or "variation margin" are  made
to  and from  the broker on  a daily basis.  This process is  called "marking to
market."
 
    The purchase and  sale of financial  futures is for  the purpose of  hedging
against  changes in  securities prices  or interest  rates. Hedging transactions
serve as a  substitute for  transactions in  the underlying  securities and  can
effectively  reduce investment risk.  When prices are expected  to rise, a Fund,
through the purchase of futures contracts,  can attempt to secure better  prices
than  might be later available in the stock market when it anticipates effecting
purchases.
 
    Similarly, when interest rates are expected to increase, a Fund can seek  to
offset a decline in the value of its debt securities through the sale of futures
contracts.
 
OPTIONS ON FINANCIAL FUTURES.
 
    The  Funds other than the Small Cap Value Fund and Money Market Fund may use
options on futures contracts in connection with hedging strategies. The purchase
of put options on futures contracts is  a means of hedging the Fund's  portfolio
against the risk of declining prices. The purchase of a call option on a futures
contract  represents a means of hedging against  a market advance when a Fund is
not fully invested. Depending  on the pricing of  the option compared to  either
the  futures contract upon which it is based or upon the price of the underlying
securities, the  option may  or may  not be  less risky  than ownership  of  the
futures contract or underlying securities.
 
    The  writing of a call option on a futures contract may constitute a partial
hedge against  declining  prices  of  the securities  or  currencies  which  are
deliverable  upon  exercise of  the futures  contract. If  the futures  price at
expiration is below the exercise  price, a Fund will  retain the full amount  of
the  option premium, which provides a partial hedge against any decline that may
have occurred in the Funds' holding of securities or currencies.
 
    The writing  of a  put option  on a  futures contract  is analogous  to  the
purchase  of a futures contract. If the option is exercised, the net cost to the
Fund of the  securities or  currencies acquired  by it  will be  reduced by  the
amount of the option premium received. If, however, market prices have declined,
the  Fund's purchase price upon exercise may  be greater than the price at which
the securities or currencies might be purchased in the cash market.
 
                                       11
<PAGE>
LIMITATIONS ON PURCHASE AND SALE OF FUTURES AND RELATED OPTIONS.
 
    A Fund  will not  engage in  transactions in  futures contracts  or  related
options  for speculation but  only as a  hedge against changes  in the values of
securities or  currencies held  in a  Fund's portfolio  or which  it intends  to
purchase.  A  Fund may  not  purchase or  sell  futures contract  if immediately
thereafter the sum  of the  amount of margin  deposits and  amount of  variation
margins  paid  from time  to time  on  the Fund's  existing futures  and related
options positions and premiums paid for  related options would exceed 5% of  the
market  value of the Fund's total assets. In instances involving the purchase of
futures contracts or call options thereon or the writing of put options  thereon
by  a Fund, an amount of cash and cash equivalents, equal to the market value of
the futures contracts and  related options (less  any related margin  deposits),
will be deposited in a segregated account with its custodian, in the name of the
broker,  to collateralize the position  and thereby insure that  the use of such
futures contracts and options is unleveraged.
 
    The extent to  which a  Fund may enter  into futures  contracts and  options
transactions  may be  limited by  the Internal  Revenue Code's  requirements for
qualification as  a regulated  investment company.  Such qualification  requires
that the Fund limit to 30% the portion of its gross income which is derived from
the  sale or other dispositions of investments  held (or considered to have been
held under Internal Revenue rules) for less than three months.
 
    In implementing a Fund's  overall risk management  strategy, it is  possible
that  its sub-adviser will choose  not to engage in  any futures transactions or
that appropriate futures contracts  or related options may  not be available.  A
Fund  will engage in  futures transactions only for  appropriate hedging or risk
management  purposes.  A  Fund  will  not  enter  into  any  particular  futures
transaction  unless its  sub-adviser determines that  the particular transaction
demonstrates an appropriate  correlation with the  Fund's investment  objectives
and portfolio securities.
 
RISKS OF TRANSACTIONS IN FUTURES.
 
    The  sale and purchase of futures contracts is a highly specialized activity
which involves investment techniques and  risks different from those  associated
with  ordinary  portfolio securities  transactions. There  are several  risks in
connection with the use of financial futures by a Fund as a hedging device.
 
    Successful  use  of  financial  futures  by   a  Fund  is  subject  to   its
sub-adviser's ability to predict movements in the direction of interest rates or
securities  prices and to assess other factors affecting markets for securities.
For example, a Fund may hedge against the possibility of an increase in interest
rates which would  adversely affect the  prices of debt  securities held in  its
portfolio.  If prices of the debt securities increase instead, the Fund may lose
part or all of the benefit of the increased value of the hedged debt  securities
because  it may have offsetting losses in the futures positions. In addition, in
this situation,  if  the  Fund  has  insufficient cash,  it  may  have  to  sell
securities  to meet daily  maintenance margin requirements.  These sales may be,
but will not necessarily be, at  increased prices to reflect the rising  market.
The Fund may have to sell securities at a time when it may be disadvantageous to
do so.
 
    Another  risk arises because of  the imperfect correlation between movements
in the  price  of  the financial  future  and  movements in  the  price  of  the
securities  or currencies which are the subject  of the hedge. First of all, the
hours of trading for futures contracts may not conform to the hours during which
the underlying assets are traded. To  the extent that the futures markets  close
before  the  markets  for  the underlying  assets,  significant  price  and rate
movements can  take  place  in  the underlying  assets  market  that  cannot  be
reflected  in the futures markets. But  even during identical trading hours, the
price of the  future may move  more than or  less than the  price of the  assets
being  hedged. While  a hedge will  not be fully  effective if the  price of the
future moves less  that the  price of  the hedged assets,  if the  price of  the
hedged  assets has  moved in an  unfavorable direction,  the Fund would  be in a
better position than  if it had  not hedged at  all. On the  other hand, if  the
price  of the hedged assets  has moved in a  favorable direction, this advantage
may be partially offset by the price movement of the
 
                                       12
<PAGE>
futures contract. If the price  of the future moves more  than the price of  the
asset,  the Fund will experience either a loss or a gain on the futures contract
which will not be  completely offset by  movements in the  prices of the  assets
which are the subject of the hedge.
 
    In  addition to the possibility that  there may be an imperfect correlation,
or no correlation at all,  between movements in the  futures and the portion  of
the  portfolio being  hedged, the  market prices of  futures may  be affected by
certain other factors. First, all participants in the futures market are subject
to margin deposit and maintenance  requirements. Rather than meeting  additional
margin  deposit  requirements, investors  may  close futures  through offsetting
transactions, which could distort the normal relationship between the securities
or currencies  and  futures  markets.  Secondly,  from  the  point  of  view  of
speculators,  the deposit  requirements in the  futures market  are less onerous
than  margin  requirements  in  the  securities  market.  Therefore,   increased
participation  by speculators  in the  futures market  may also  cause temporary
price or currency distortions. Due to the possibility of price distortion in the
futures market and because of the imperfect correlation between movements in the
prices of securities  or currencies and  movements in the  prices of futures,  a
correct  forecast  of interest  rate  trends or  market  price movements  by the
sub-adviser may still  not result  in a  successful hedging  transaction over  a
short time frame.
 
    Positions  in futures  contracts may  be closed out  only on  an exchange or
board of trade which provides a secondary market for such futures. Although  the
Funds  intend to purchase or  sell futures only on  exchanges or boards of trade
where there appears to be an active secondary market, there is no assurance that
a liquid secondary market on  an exchange or board of  trade will exist for  any
particular  contract or at any  particular time. Thus it  may not be possible to
close a futures position, and, in the event of adverse price movements, the Fund
would continue to be required to make daily cash payments of maintenance margin.
However, in the event futures have been used to hedge portfolio positions,  such
underlying  assets will not be sold until the futures can be terminated. In such
circumstances, an increase in  the price of the  underlying assets, if any,  may
partially or completely offset losses on the future.
 
RISKS OF TRANSACTIONS IN OPTIONS ON FUTURES.
 
    There  are several special risks relating  to options on futures. First, the
ability to  establish and  close out  positions  in options  is subject  to  the
maintenance  of a liquid secondary  market. A Fund will  not purchase options on
futures on any exchange  or board of  trade unless, in the  opinion of its  sub-
adviser, the market for such options is developed sufficiently that the risks in
connection  with options on futures transactions  are not greater than the risks
in connection with  futures transactions. Compared  to the purchase  or sale  of
futures,  the purchase of call or put options on futures involves less potential
risk to the Fund because the maximum amount at risk is the premium paid for  the
options  (plus transaction costs). However, there  may be circumstances when the
purchase of a call or put option on  futures would result in a loss to the  Fund
when  the purchase  or sale  of a  future would  not, such  as when  there is no
movement in the price of the underlying securities. The writing of an option  on
a futures contract involves risks similar to those risks relating to the sale of
futures contracts, described above under RISKS OF TRANSACTIONS IN FUTURES.
 
    An  option position may be closed out only  on an exchange or board of trade
which provides a secondary market for an  option of the same series. Although  a
Fund will generally purchase only those options for which there appears to be an
active  secondary market, there  is no assurance that  a liquid secondary market
will exist for any particular option or at any particular time. It might not  be
possible  to effect closing transactions in  particular options, with the result
that the Fund would have to exercise its options in order to realize any  profit
and would incur transaction costs upon the sale of financial futures pursuant to
the exercise of put options.
 
    Because  of  the risks  and the  transaction  costs associated  with hedging
activities, there can be  no assurance that a  Fund's portfolio will perform  as
well  as  or better  than  a comparable  fund that  does  not invest  in futures
contracts or related options.

FORWARD CONTRACTS ON FOREIGN CURRENCIES
 
    A forward contract is an agreement between two parties in which one party is
obligated to deliver a stated  amount of a stated asset  at a specified time  in
the  future and the other  party is obligated to  pay a specified invoice amount
for the assets at the time of delivery. The Select Capital Appreciation Fund may
enter into forward contracts to purchase and sell government securities, foreign
currencies or  other  financial  instruments. Forward  contracts  generally  are
traded  in an interbank market conducted directly between traders (usually large
commercial banks)  and  their customers.  Unlike  futures contracts,  which  are
standardized  contracts, forward contracts can be specifically drawn to meet the
needs of the parties that enter into them. The parties to a forward contract may
agree to offset or terminate the contract  before its maturity, or may hold  the
contract  to  maturity and  complete  the contemplated  exchange.  The following
discussion summarizes the Select Capital  Appreciation Fund's principal uses  of
forward  currency exchange  contracts ("forward currency  contracts"). Such Fund
may enter into forward  currency contracts with stated  contract value of up  to
the value of such Fund's assets. A forward currency contract is an obligation to
buy  or sell an amount of a specified currency for an agreed price (which may be
in U.S. dollars  or a foreign  currency). The Select  Capital Appreciation  Fund
will  exchange  foreign  currencies  for  U.S.  dollars  and  for  other foreign
currencies in the  normal course  of business and  may buy  and sell  currencies
through forward currency contracts in order to fix a price for securities it has
agreed  to buy  or sell ("transaction  hedge"). The  Select Capital Appreciation
Fund also  may hedge  some or  all  of its  investments denominated  in  foreign
currency  against a decline in  the value of that  currency relative to the U.S.
dollar by entering  into forward currency  contracts to sell  an amount of  that
currency  (or a  proxy currency  whose performance  is expected  to replicate or
exceed the  performance  of  that  a  currency  relative  to  the  U.S.  dollar)
approximating  the value of some or  all of its portfolio securities denominated
in that currency ("position  hedge") or by participating  in options or  futures
contracts  with respect to the currency. Such Fund also may enter into a forward
currency contract with respect to a currency where that Fund is considering  the
purchase  or sale of  investments denominated in  that currency but  has not yet
selected the specific investments ("anticipatory hedge").
 
    In any  of these  circumstances the  Select Capital  Appreciation Fund  may,
alternatively,  enter into a  forward currency contract to  purchase or sell one
foreign currency  for  a  second  currency that  is  expected  to  perform  more
favorably  relative to the  U.S. dollar if  its sub-adviser believes  there is a
reasonable degree  of  correlation  between  movements  in  the  two  currencies
("cross-hedge").
 
    These  types of hedging minimize the effect of currency appreciation as well
as depreciation, but do not eliminate fluctuations in the underlying U.S. dollar
equivalent value of the proceeds  of or rates of  return on such Fund's  foreign
currency denominated portfolio securities. The matching of the increase in value
of a forward contract and the decline in the U.S. dollar equivalent value of the
foreign  currency denominated asset  that is the subject  of the hedge generally
will not be  precise. Shifting such  Fund's currency exposure  from one  foreign
currency  to another removes that Fund's opportunity to profit from increases in
the value of the original  currency and involves a  risk of increased losses  to
such   Fund  if  its  sub-adviser's  projection  of  future  exchange  rates  is
inaccurate. Proxy hedges and cross-hedges may  result in losses if the  currency
used  to  hedge does  not  perform similarly  to  the currency  in  which hedged
securities are denominated. Unforeseen changes in currency prices may result  in
poorer  overall performance for the Select  Capital Appreciation Fund than if it
had not entered into such contracts.
 
    The Select Capital Appreciation Fund will cover outstanding forward currency
contracts by maintaining liquid portfolio securities denominated in the currency
underlying the forward contract or the currency being hedged. To the extent that
the Select Capital Appreciation Fund is  not able to cover its forward  currency
positions  with  underlying  portfolio securities,  such  Fund's  custodian will
segregate cash or high-grade liquid assets having a value equal to the aggregate
amount of its commitments under forward  contracts entered into with respect  to
position  hedges,  cross-hedges and  anticipatory hedges.  If  the value  of the
securities  used   to   cover   a   position  or   the   value   of   segregated
 
                                       14
<PAGE>
assets  declines,  the Select  Capital Appreciation  Fund will  find alternative
cover or segregate additional cash or high-grade liquid assets on a daily  basis
so  that the value of the covered segregated  assets will be equal to the amount
of such Fund's commitments with respect to such contracts. As an alternative  to
segregating  assets, the Select  Capital Appreciation Fund  may buy call options
permitting it to buy the  amount of foreign currency  being hedged by a  forward
sale  contract or such Fund may buy put options permitting it to sell the amount
of foreign currency subject to a forward buy contract.
 
    While forward contracts are  not currently regulated by  the CFTC, the  CFTC
may in the future assert authority to regulate forward contracts. In such event,
the  Select Capital Appreciation Fund's ability to utilize forward contracts may
be restricted. In addition, the Select Capital Appreciation Fund may not  always
be  able to enter into forward contracts at attractive prices and may be limited
in its ability to use these contracts to hedge portfolio assets.
 
SWAP AND SWAP-RELATED PRODUCTS
 
    The Select Capital  Appreciation Fund  may enter into  interest rate  swaps,
caps  and floors  on either an  asset-based or  liability-based basis, depending
upon whether it is hedging its assets or its liabilities, and will usually enter
into interest rate  swaps on  a net  basis (i.e.,  the two  payment streams  are
netted  out with the Fund receiving or paying,  as the case may be, only the net
amount of the  two payments). Interest  rate swaps involve  the exchange by  the
Fund  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 of two or more  currencies
based  on  the relative  value  differential among  them.  An index  swap  is an
agreement to swap 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 such cap
to the extent that  a specified index exceeds  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 such floor to the extent that a
specified index falls below a predetermined interest rate or amount.
 
   
    The net amount of  the excess, if  any, of the  Fund's obligations over  its
entitlement  with respect  to each  interest rate swap  will be  calculated on a
daily basis  and  an  amount of  cash  or  high-grade liquid  assets  having  an
aggregate  net  asset  value  at  least equal  to  the  accrued  excess  will be
maintained in a segregated account by  the Fund's custodian. If the Fund  enters
into  an interest  rate swap  on other  than a  net basis,  it would  maintain a
segregated account  in  the  full  amount  accrued  on  a  daily  basis  of  its
obligations  with respect to the swap. The Fund will not enter into any interest
rate swap, cap  or floor  transaction unless the  unsecured senior  debt or  the
claims-paying  ability of the other  party thereto is rated  in one of the three
highest rating  categories of  at least  one nationally  recognized  statistical
rating  organization  at  the  time  of  entering  into  such  transaction.  The
sub-adviser will  monitor  the  creditworthiness of  all  counterparties  on  an
ongoing  basis. If there is a default by  the other party to such a transaction,
the Fund will 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 and floors are more recent innovations for  which
standardized documentation has not yet been developed and, accordingly, they are
less  liquid than swaps.  To the extent  the Fund sells  (i.e., writes) caps and
floors, it will segregate cash or  high-grade liquid assets having an  aggregate
net  asset value  at least  equal to  the full  amount on  a daily  basis of its
obligations with respect to any caps or floors.
 
    There is no limit on the amount of interest rate swap transactions that  may
be  entered into by the  Fund. These transactions may  in some instances involve
the delivery  of  securities or  other  underlying assets  to  the Fund  or  its
counterparty   to   collateralize  obligations   under   the  swap.   Under  the
documentation currently used in those markets, the risk of loss with respect  to
interest rates swaps is limited to
 
                                       15
<PAGE>
the net amount of the payments that the Fund is contractually obligated to make.
If the other party to an interest rate swap that is not collateralized defaults,
the  Fund  would  risk the  loss  of the  net  amount  of the  payments  that it
contractually is entitled to  receive. The Fund may  buy and sell (i.e.,  write)
caps  and  floors without  limitation,  subject to  the  segregation requirement
described above.
 
ADDITIONAL RISKS OF OPTIONS ON FOREIGN CURRENCIES, FORWARD CONTRACTS AND FOREIGN
INSTRUMENTS
 
    Unlike transactions entered into by the Funds in futures contracts,  options
on  foreign currencies and forward contracts  are not traded on contract markets
regulated by  the  CFTC or  (with  the  exception of  certain  foreign  currency
options)  by  the SEC.  To  the contrary,  such  instruments are  traded through
financial  institutions  acting  as  market-makers,  although  foreign  currency
options  are also  traded on certain  exchanges, such as  the Philadelphia Stock
Exchange and  the Chicago  Board Options  Exchange, subject  to SEC  regulation.
Similarly,   options  on  currencies  may  be  traded  over-the-counter.  In  an
over-the-counter trading  environment,  many  of  the  protections  afforded  to
exchange  participants will  not be available.  For example, there  are no daily
price fluctuation limits, and adverse market movements could therefore  continue
to  an unlimited extent over  a period of time. Although  the buyer of an option
cannot lose more than the amount of the premium plus related transaction  costs,
this  entire amount  could be lost.  Moreover, an  option writer and  a buyer or
seller of  futures or  forward  contracts could  lose amounts  substantially  in
excess of any premium received or initial margin or collateral posted due to the
potential  additional margin  and collateral  requirements associated  with such
positions.
 
    Options  on  foreign   currencies  traded  on   exchanges  are  within   the
jurisdiction  of the SEC, as are other securities traded on such exchanges. As a
result, many of the protections provided to traders on organized exchanges  will
be  available  with respect  to such  transactions.  In particular,  all foreign
currency option positions entered into on an exchange are cleared and guaranteed
by the Office of the Comptroller  of the Currency ("OCC"), thereby reducing  the
risk  of counterparty  default. Further,  a liquid  secondary market  in options
traded on an exchange may be more readily available than in the over-the-counter
market, potentially permitting a  Fund to liquidate open  positions at a  profit
prior  to exercise  or expiration, or  to limit  losses in the  event of adverse
market movements.
 
    The purchase and sale of exchange-traded foreign currency options,  however,
is  subject  to the  risks  of the  availability  of a  liquid  secondary market
described above,  as  well as  the  risks regarding  adverse  market  movements,
margining  of  options  written,  the nature  of  the  foreign  currency market,
possible intervention  by  governmental authorities  and  the effects  of  other
political  and economic events. In  addition, exchange-traded options on foreign
currencies involve certain risks not  presented by the over-the-counter  market.
For  example, exercise and  settlement of such options  must be made exclusively
through the  OCC,  which has  established  banking relationships  in  applicable
foreign  countries for this purpose. As a  result, the OCC may, if it determines
that  foreign  government  restrictions  or  taxes  would  prevent  the  orderly
settlement  of  foreign  currency option  exercises,  or would  result  in undue
burdens on the OCC or its clearing member, impose special procedures on exercise
and settlement, such  as technical  changes in  the mechanics  of delivery,  the
fixing of dollar settlement prices or prohibitions on exercise.
 
    In  addition,  options  on U.S.  Government  securities,  futures contracts,
options  on  futures  contracts,  forward  contracts  and  options  on   foreign
currencies  may be traded  on foreign exchanges  and over-the-counter in foreign
countries. Such transactions  are subject  to the risk  of governmental  actions
affecting  trading in  or the  prices of  foreign currencies  or securities. The
value of such positions  also could be adversely  affected by (i) other  complex
foreign  political and  economic factors, (ii)  lesser availability  than in the
United States of  data on which  to make  trading decisions, (iii)  delays in  a
Fund's  ability to act upon economic  events occurring in foreign markets during
non-business hours  in  the United  States,  (iv) the  imposition  of  different
exercise and settlement terms and procedures and margin requirements than in the
United States, and (v) low trading volume.

                               PORTFOLIO TURNOVER
 
    The  portfolio turnover rate for a Fund is calculated by dividing the lesser
of purchases or sales of  portfolio securities by the Fund  for a given year  by
the  monthly average of  the value of  the Fund's portfolio  securities for that
year. The purchase  or sale  of all  securities whose  maturities or  expiration
dates  at the time  of acquisition are less  than 12 months  and of money market
funds of amounts too small to invest in short-term obligations are not  included
in the portfolio turnover rate.
 
   
    While  the rate of portfolio turnover is  not a limiting factor when changes
in the portfolio  are deemed appropriate,  it is anticipated  that under  normal
circumstances  the annual  portfolio turnover  rate would  not exceed  200% with
respect to  the  Select  Capital  Appreciation Fund.  In  any  particular  year,
however,  conditions could result in portfolio activities at a greater rate than
anticipated. In any  case, a  higher turnover  rate does  not in  and of  itself
indicate a variation from the stated investment policy. To a limited extent, the
Select  Capital Appreciation Fund  may engage in a  short-term trading. A higher
portfolio turnover rate may involve corresponding greater brokerage  commissions
and other transaction costs, which would be borne directly by each Fund, as well
as  additional realized gains  and/or losses to  shareholders. The turnover rate
for the Select International Equity  Fund, Select Aggressive Growth Fund,  Small
Cap  Value Fund, Growth Fund, Select Growth Fund, Select Growth and Income Fund,
Equity Index Fund, Investment Grade Income Fund, Government Bond Fund and Select
Income Fund for the two  most recent fiscal years  ended December 31, 1995  were
24% and 19%; 104% and 100%; 17% and 4%; 64% and 46%; 51% and 55%; 112% and 107%;
8%  and 7%; 126% and 129%; 180%  and 106% (for explanation see Prospectus); 131%
and 105%, respectively. The  turnover rate for  the Select Capital  Appreciation
Fund for the period ended December 31, 1995 was 95%.
    
 
                                  PERFORMANCE
 
    The  Trust  may  advertise performance  information  for the  Funds  and may
compare performance of the  Funds to other investment  or relevant indices.  The
Funds may also advertise "yield", total return" and other non-standardized total
return  data. For the non-money market  funds, "yield" is calculated differently
than for the Money Market Fund. The  Money Market Fund may advertise "yield"  or
"effective  yield". ALL PERFORMANCE FIGURES ARE BASED ON HISTORICAL EARNINGS AND
ARE NOT INTENDED TO INDICATE FUTURE  PERFORMANCE. The Funds' share price,  yield
and  total return fluctuate in response  to market conditions and other factors,
and the  value of  Fund shares  when redeemed  may be  more or  less than  their
original cost.
 
    YIELDS  AND  TOTAL  RETURNS  QUOTED  FOR THE  FUNDS  INCLUDE  THE  EFFECT OF
DEDUCTING THE  FUNDS'  EXPENSES,  BUT  MAY  NOT  INCLUDE  CHARGES  AND  EXPENSES
ATTRIBUTABLE TO A PARTICULAR INSURANCE PRODUCT. SINCE SHARES OF THE FUNDS CAN BE
PURCHASED  ONLY THROUGH A VARIABLE ANNUITY OR VARIABLE LIFE CONTRACT, YOU SHOULD
CAREFULLY REVIEW THE  PROSPECTUS OF THE  INSURANCE PRODUCT YOU  HAVE CHOSEN  FOR
INFORMATION  ON RELEVANT  CHARGES AND EXPENSES.  INCLUDING THESE  CHARGES IN THE
QUOTATIONS OF  THE  FUNDS' YIELD  AND  TOTAL RETURN  WOULD  HAVE THE  EFFECT  OF
DECREASING  PERFORMANCE. PERFORMANCE INFORMATION FOR  THE INSURANCE PRODUCT MUST
ALWAYS ACCOMPANY, AND BE REVIEWED  WITH, ANY PERFORMANCE INFORMATION QUOTED  FOR
THE FUNDS.

YIELD OF THE FUNDS OTHER THAN THE MONEY MARKET FUND
 
    The  30-day (or one month) standard yield  of the Funds other than the Money
Market Fund is calculated as follows:
 
                           a - b
               YIELD = 2[( ----- + 1)(6) - 1)]
                            cd
 
    Where: a = dividends and interest earned by a
               Fund during the period;
           b = expenses accrued for the period
               (net of reimbursements);
           c = average daily number of shares outstanding during the
               period,
               entitled to receive dividends; and
           d = maximum offering price per share on the last day of the
               period.
 
    For the  purpose of  determining  net investment  income earned  during  the
period  (variable "a" in the formula), dividend income on equity securities held
by a Fund is  recognized by accruing  1/360 of the stated  dividend rate of  the
security  each day  that the  security is  in the  Fund. Except  as noted below,
interest earned on debt  obligations held by a  Fund is calculated by  computing
the  yield  to maturity  of each  obligation based  on the  market value  of the
obligation (including actual accrued interest) at  the close of business on  the
last  business  day of  each month,  or, with  respect to  obligations purchased
during the month, the purchase price (plus actual accrued interest) and dividing
the result  by 360  and multiplying  the quotient  by the  market value  of  the
obligation  (including  actual  accrued  interest)  in  order  to  determine the
interest income on the obligation for each day of the subsequent month that  the
obligation  is held by the Fund. For purposes of this calculation, it is assumed
that each month  contains 30 days.  The maturity  of an obligation  with a  call
provision  is  the next  call date  on  which the  obligation reasonably  may be
expected to be  called or,  if none,  the maturity  date. With  respect to  debt
obligations  purchased at a discount or premium, the formula generally calls for
amortization of  the discount  or  premium. The  amortization schedule  will  be
adjusted   monthly  to  reflect  changes  in  the  market  value  of  such  debt
obligations. Expenses  accrued for  the  period (variable  "b" in  the  formula)
include  all recurring  fees charged  by a Fund  to all  shareholder accounts in
proportion to the  length of the  base period  and the Fund's  mean (or  median)
account  size. Undeclared  earned income  will be  subtracted from  the offering
price per share (variable "d" in the formula).
 
MONEY MARKET FUND -- YIELD AND EFFECTIVE YIELD
 
    The yield of the Money Market Fund refers to the net income generated by  an
investment  in the Fund over  a stated seven-day period,  expressed as an annual
percentage rate. Yield is computed by  determining the net change (exclusive  of
capital  changes) in the  value of a hypothetical  pre-existing account having a
balance of  1 (one)  share at  the  beginning of  a seven-day  calendar  period,
dividing  the net  change in account  value by the  value of the  account at the
beginning of the period, and multiplying the return over the seven-day period by
365/7. Thus the income  is "annualized": the amount  of income generated by  the
investment during the seven-day period is assumed to be generated each week over
a 52-week period and is shown as a percentage of the investment. For purposes of
the  calculation, net change  in account value reflects  the value of additional
shares purchased with dividends from  the original share and dividends  declared
on  both the  original share  and any  additional shares,  but does  not reflect
realized gains or losses or unrealized appreciation or depreciation.
 
    The effective yield  is calculated similarly,  but the income  earned by  an
investment  in the Money Market Fund is assumed to be reinvested. The "effective
yield" will be  slightly higher  than the  "yield" because  of this  compounding
effect.
 
                                       18
<PAGE>
TOTAL RETURN
 
    The  Funds  may  advertise total  return.  The  total return  shows  what an
investment in each Fund would have earned  over a specific period of time  (one,
five  or ten years or  since commencement of operations,  if less) assuming that
all distributions  and dividends  by  the Fund  were  reinvested, and  less  all
recurring fees.
 
    From time to time, the Fund may state its total return in advertisements and
investor  communications. Total return may be  stated for any relevant period as
specified in the advertisement or  communication. Any statement of total  return
or  other performance data on the Fund will be accompanied by information on the
Fund's average annual total return over  the most recent four calendar  quarters
and  the  period from  the Fund's  inception  of operations.  The Fund  may also
advertise aggregate annual  total return information  over different periods  of
time.
 
    A  Fund's  average  annual total  return  is  determined by  reference  to a
hypothetical  $1,000   investment  that   includes  capital   appreciation   and
depreciation for the stated period, according to the following formula:
 
                                 P(1+T)n = ERV
 
    Where: P = A hypothetical initial purchase of $1,000
           T = average annual total return
           n = number of years
         ERV = Ending Redeemable Value of the hypothetical purchase at the
               end of the period
 
    Total  return  quoted  in advertising  reflects  all aspects  of  the Fund's
return,  including  the  effect  of  reinvesting  dividends  and  capital  gains
distributions,  and any change in the Fund's  net asset value per share over the
period.
 
    AVERAGE ANNUAL RETURNS are calculated by determining the change in value  of
a  hypothetical investment in the Fund over a stated period, and calculating the
annually compounded percentage rate that would have produced the same result  if
the  rate  of growth  or decline  in value  has been  constant over  the period.
Average annual returns covering periods of less than one year are calculated  by
determining  the Fund's total  return for the  period, extrapolating that return
for a full year, and stating the result as an annual return. Because this method
assumes that performance will remain constant for the entire year, when in  fact
it is unlikely that performance will remain constant, average annual returns for
a partial year must be viewed as strictly theoretical information.
 
    INVESTORS  SHOULD ALSO  BE AWARE THAT  A FUND'S PERFORMANCE  IS NOT CONSTANT
OVER TIME,  BUT  VARIES FROM  YEAR  TO  YEAR. AVERAGE  ANNUAL  RETURN  REPRESENT
AVERAGED FIGURES AS OPPOSED TO THE ACTUAL PERFORMANCE OF THE FUND.
 
    A  Fund may  also quote  cumulative total  returns which  reflect the simple
change in value  of an  investment over a  stated period.  Average annual  total
returns  and cumulative  total returns  may be  quoted as  a percentage  or as a
dollar amount. They may be calculated for  a single investment, for a series  of
investments,  or for a series of redemptions over any time period. Total returns
may be broken down into their components of income and capital in order to  show
their  respective contributions to total  return. Performance information may be
quoted numerically or in a table, graph or similar illustration.
 
OTHER PERFORMANCE INFORMATION
 
    Performance information for a Fund may be compared to: (1) the S&P 500,  Dow
Jones  Industrial Average, Shearson  Lehman Aggregate Bond  Index, Russell 2000,
Russell 3000, Beta Adjusted Russell  3000, Shearson Lehman Government  corporate
and  90 day Treasury  Bills, Solomon High  Yield Bond Index,  Bank Rate Monitor,
NASDAQ Index or other unmanaged indices  so that investors may compare a  Fund's
results  with  those  of a  group  of  unmanaged securities  widely  regarded by
investors as

representative of  the  securities  markets in  general;  (2)  other  registered
investment  companies  or  other  investment  products  tracked  (a)  by  Lipper
Analytical Services, Morningstar, Inc. and IBC/ Donoghues, Inc., all widely used
independent  research  firms  which  rank  mutual  funds  and  other  investment
companies  by overall performance, investment objectives,  and assets, or (b) by
other services, companies,  publications, or  persons who  rank such  investment
companies  on overall performance  or other criteria; (3)  or the Consumer Price
Index (a  measure for  inflation) to  assess the  real rate  of return  from  an
investment  in  the  Fund.  Unmanaged indices  may  assume  the  reinvestment of
dividends but  generally  do  not  reflect  deductions  for  administrative  and
management costs and expenses.
 
    Performance  information  reflects only  the  performance of  a hypothetical
investment during  the particular  time  period on  which the  calculations  are
based.  Performance information should be considered  in light of the investment
objectives and policies, characteristics and quality of the Fund and the  market
conditions  during the given time period. Yield and total return information may
be useful for reviewing the  performance of the Fund  and for providing a  basis
for comparison with other investment alternatives. However, unlike bank deposits
or  other investments which pay  a fixed yield for a  stated period of time, the
yield and total return do fluctuate.

litigation  in which  they may  be involved  because of  their offices  with the

Declaration that they have not acted in good faith in the reasonable belief that
their   actions  were  in  the  best  interests   of  the  Trust  or  that  such
indemnification would relieve  any officer or  Trustee of any  liability to  the
Trust  or its  shareholders by reason  of willful misfeasance,  bad faith, gross
negligence or reckless disregard of his or her duties.

interest of the shareholders of such Fund, by the Trustees, or by the investment
adviser  to such Fund without  payment of any penalty on  not more than 60 days'
written  notice;   provided,  however,   that  the   agreement  will   terminate
automatically  in  the event  of  its assignment.  Each  of the  agreements will
continue in effect as to any Fund for a period more than two years from the date
of its execution only  so long as such  continuance is specifically approved  at
least  annually by  the Trustees  or by vote  of a  majority in  interest of the
shareholders of  such  Fund. In  either  event  such continuance  also  must  be
approved  by vote  of a  majority of  the Trustees  who are  not parties  to the
agreement or interested persons  of the Trust, the  Manager or any  sub-adviser,
cast  in person at a meeting called for the purpose of voting such approval. The
terms of each agreement cannot be changed as to any Fund without the approval of
a majority in interest of the shareholders of that Fund. Under such  agreements,
any  liability of either the  Manager or a sub-adviser  is limited to situations
involving its  willful  misfeasance, bad  faith,  gross negligence  or  reckless
disregard of its obligations and duties.

agreement with JAL. The wholly owned  subsidiary of Baker Fentress, to be  known
as John A. Levin & Co., Inc., will be the sub-adviser.

                              BROKERAGE ALLOCATION
 
    In accordance with the Management Agreement and sub-advisory agreements, the
respective sub-adviser has the responsibility  for the selection of brokers  for
the  execution  of purchases  and  sales of  the  securities in  a  given Fund's
portfolio subject to the direction of  the Trustees. The sub-advisers place  the
Funds'  portfolio  transactions  with  brokers  and,  if  applicable,  negotiate
commissions.
 
    Broker-dealers may receive brokerage  commissions on portfolio  transactions
of  the Funds. The sub-advisers also  may place portfolio transactions with such
broker-dealers acting as principal, in which case, no brokerage commissions  are
payable,  but other transaction costs are incurred. The Funds have not dealt nor
do they intend to deal exclusively with any particular broker-dealer or group of
broker-dealers. It is  each Fund's policy  always to seek  best execution.  This
means  that each Fund's portfolio transactions will be placed where the Fund can
obtain the  most  favorable  combination  of price  and  execution  services  in
particular transactions or as provided on a continuing basis by a broker-dealer,
and that the Fund will deal directly with a principal market maker in connection
with  over-the-counter  transactions,  except  when  it  is  believed  that best
execution is obtainable  elsewhere. In  evaluating the execution  services of  a
broker-dealer, including the overall reasonableness of its brokerage commissions
paid,  consideration is  given to the  firm's general  execution and operational
capabilities, and  to  its  reliability,  integrity,  and  financial  condition.
Subject  to the practice of always seeking best execution, the Funds' securities
transactions may  be  executed  by  broker-dealers  who  also  provide  research
services (as defined below) to the Funds, the sub-advisers and the other clients
advised by the sub-advisers. The sub-advisers may use all, some, or none of such
research  services  in providing  investment advisory  services  to each  of its
investment company and other  clients, including the Funds.  To the extent  that
such services are used, they tend to reduce the expenses of the sub-advisers. In
the opinion of the sub-advisers it is impossible to assign an exact dollar value
to such services.
 
BROKERAGE AND RESEARCH SERVICES.
 
   
    The  agreements provide that,  subject to such policies  as the Trustees may
determine, the sub-advisers may cause a given Fund to pay a broker-dealer  which
provides brokerage and research services an amount of commission for effecting a
securities transaction for that Fund in excess of the amount of commission which
another  broker-dealer  would have  charged for  effecting that  transaction. As
provided in Section 28(e) of the Securities Exchange Act of 1934, "brokerage and
research  services"  include  advice  as   to  the  value  of  securities,   the
advisability   of  investing   in,  purchasing,   or  selling   securities,  the
availability of securities  or purchasers or  sellers of securities;  furnishing
analyses  and  reports  concerning  issuers,  industries,  securities,  economic
factors  and  trends,  portfolio  strategy  and  performance  of  accounts;  and
effecting  securities transactions  and performing  functions incidental thereto
(such as  clearance and  settlement). The  sub-advisers must  determine in  good
faith that such greater commission is reasonable in relation to the value of the
brokerage  and research services provided  by the executing broker-dealer viewed
in terms of that particular transaction  or the overall responsibilities of  the
sub-advisers  to its  respective Funds and  all other  clients. The sub-advisers
also may  consider  sales  by  broker-dealers  of  variable  and  group  annuity
contracts and variable life insurance policies that contemplates the Funds as an
investment  option as  a factor  in the  selection of  broker-dealers to execute
portfolio transactions.
    
 
    The other  investment  companies and  clients  advised by  the  sub-advisers
sometimes  invest in  securities in which  the Funds also  invest. A sub-adviser
also may invest for its own account in the
 
                                       26
<PAGE>
securities in  which the  Funds  invest. If  the  Funds, such  other  investment
companies  and other clients of the sub-advisers  desire to buy or sell the same
portfolio security at about the same time, the purchases and sales normally  are
made  as nearly as practicable on a pro  rata basis in proportion to the amounts
desired to be purchased  or sold by  each. It is recognized  that in some  cases
this  practice could  have a detrimental  effect on  the price or  volume of the
security as far  as the  Funds are  concerned. In  other cases,  however, it  is
believed  that this practice may produce better executions. It is the opinion of
the Trustees that the  desirability of retaining  the sub-adviser as  investment
advisers  to their respective  Funds outweighs the  disadvantages, if any, which
might result from this practice.

for the  Select  Capital  Appreciation  Fund were  $94,679  in  1995.  Brokerage
commissions  for the Select Growth Fund were  $147,728 in 1995, $128,621 in 1994
and $73,304 in 1993. Brokerage commissions for the Select Growth and Income Fund
were $458,046  in  1995,  $370,133  in  1994  and  $94,032  in  1993.  Brokerage
commissions  for the  Growth Fund  were $577,791 in  1995, $341,751  in 1994 and
$324,747 in 1993. Brokerage commissions for the Select Income Fund were $132,407
in 1994. Brokerage commissions for the  Equity Index Fund were $28,468 in  1995,
$15,682  in 1994 and  $16,913 in 1993.  Brokerage commissions for  the Small Cap
Value Fund were $54,538 in 1995, $66,517 in 1994 and $35,194 in 1993.  Brokerage
commissions for the Investment Grade Income Fund were $78,654 in 1993. Brokerage
commissions  for the Government Bond Fund were  $16,759 in 1995. The other Funds
did not incur brokerage commissions in any of these years.
    
 
   
DIRECTED BROKERAGE PROGRAM
    
 
   
    The sub-advisers of certain Funds may consider payments made to a Fund or to
other persons on behalf of the Fund for services provided to the Fund for  which
the  Fund would  otherwise be obligated  to buy  when such payments  are made by
brokers effecting transactions for  such Fund. Some Funds  have entered into  an
agreement  with certain  brokers whereby  the brokers  will rebate  a portion of
commissions. Such amounts earned by the Funds during 1995 under such  agreements
were  as follows: Select  International Equity Fund,  $11,687; Select Aggressive
Growth Fund, $2,753; Small Cap Value Fund, $7,929; Growth Fund, $85,334;  Select
Growth Fund, $11,423; and Select Growth and Income Fund, $24,078.
    
 
         PURCHASE, REDEMPTION, AND PRICING OF SECURITIES BEING OFFERED
 
    As described in the Prospectus, shares of each Fund are sold and redeemed at
their  net  asset  value as  next  computed  after receipt  of  the  purchase or
redemption order.  Each purchase  is  confirmed to  the  Separate Account  in  a
written  statement of the number of shares purchased and the aggregate number of
shares currently held.
 
    The net asset value per share of each  Fund is the total net asset value  of
that Fund divided by the number of shares outstanding. The total net asset value
of  each Fund is determined  by computing the value of  the total assets of that
Fund and deducting  total liabilities,  including accrued  liabilities. The  net
asset  value of the shares of each Fund is determined once daily as of the close
of the New York  Stock Exchange on each  day on which the  Exchange is open  for
trading,  and no less frequently than once daily on each other day (other than a
day during which no shares of the Fund were tendered for redemption and no order
to purchase or sell such shares was received  by the Fund) in which there was  a
sufficient degree in trading in the Fund's portfolio securities that the current
net  asset value of the Fund's shares might be materially affected by changes in
the value of such portfolio securities.
 
    Debt securities for which  market quotations are  not readily available  are
valued at fair value by using valuation procedures approved in good faith by the
Trustees.  As authorized by the Trustees, debt securities (other than short-term
obligations) of the Funds  other than the  Money Market Fund  are valued on  the
basis  of  valuations  furnished  by  a  pricing  service  which  utilizes  data
processing  methods  to  determine  valuations  for  normal,  institutional-size
trading units of such securities. Such
 
                                       27
<PAGE>
methods  include the  use of market  transactions for  comparable securities and
various relationships  between  securities  which are  generally  recognized  by
institutional  traders.  Short-term obligations  having remaining  maturities of
sixty (60) days or less are valued at amortized cost.
 
    Short-term debt securities  of the Funds  other than the  Money Market  Fund
having  a remaining maturity of more than sixty (60) days will be valued using a
"marking-to-market" method based upon either the readily available market  price
or,  if reliable market quotations are not available, upon quotations by dealers
or issuers for securities of a similar type, quality, and maturity. "Marking-to-
market" takes  into  account  unrealized appreciation  or  depreciation  due  to
changes  in interest  rates or other  factors which would  influence the current
fair value of such securities.
 
    All portfolio securities  of the  Money Market Fund  will be  valued by  the
amortized  cost method. The purpose of this  method of calculation is to attempt
to maintain a constant net asset value per share of $1.00, but no assurance  can
be  given that this goal can be  attained. Amortized cost is an approximation of
market value determined  by systematically  increasing the carrying  value of  a
security  acquired at a discount, or  systematically reducing the carrying value
of a security  acquired at a  premium, so that  the carrying value  is equal  to
maturity  value  on  the maturity  date.  It  does not  take  into consideration
unrealized gains or losses. While  the amortized cost method provides  certainty
and consistency in portfolio valuation, it may result in valuations of portfolio
securities  which are higher  or lower than  the prices at  which the securities
could be sold. During such periods, the yield to investors in a Fund may  differ
somewhat  from that obtained if  the Fund were to  use mark-to-market values for
its portfolio securities. For example, if the use of amortized cost resulted  in
a  lower (higher) aggregate  portfolio value on a  particular day, a prospective
investor in the  Fund would obtain  a somewhat higher  (lower) yield than  would
result  from marked-to- market  valuation, and existing  investors would receive
less (more) investment income.
 
    The use of the amortized cost method  of valuation by the Money Market  Fund
is  subject to rules of the Securities and Exchange Commission. Under the rules,
the Fund is required to maintain a dollar weighted average portfolio maturity of
90 days  or less  and to  limit its  investments to  instruments which  (1)  its
sub-adviser,  subject to the guidelines  established by the Trustees, determines
present minimal  credit risks,  (2)  have high  quality  ratings or  are  deemed
comparable,  such that they are "eligible  securities" as defined below, and (3)
have remaining maturity of  thirteen months (397  days) or less  at the time  of
purchase,  or  are  subject to  a  demand  feature which  reduces  the remaining
maturity to thirteen months or less.
 
    The Money  Market Fund  may only  purchase "First  or Second  Tier  eligible
securities" which are defined to include: (1) securities which have received the
highest  or  second  highest  rating  by  at  least  two  nationally  recognized
statistical rating organizations ("NRSRO") or by only one NRSRO if only one  has
rated   the  security  and  (2)  securities  which  are  unrated,  but,  in  the
sub-adviser's opinion,  are of  comparable quality.  The Money  Market Fund  may
purchase  securities  which  were long-term  at  issuance but  have  a remaining
maturity of thirteen months or less at the time of purchase, if: (a) the  issuer
has  comparable  short-term  debt  securities  outstanding  which  are  eligible
securities or (b) the  issuer has no short-term  rating and the securities  have
either  no long-term  rating or  a long-term  rating in  one of  the two highest
categories by an NRSRO.
 
    The above standards must be satisfied at the time an investment is made.  If
the  quality of the investment  later declines, the Fund  (a) may dispose of the
security within five business days of the sub-adviser becoming aware of the  new
rating,  or  (b) may  continue to  hold  the investment,  but the  Trustees will
evaluate whether the security continues to present minimal credit risks.
 
    As a part of the overall duty  of care they owe to the Fund's  shareholders,
the  Trustees have established  procedures reasonably designed  to stabilize the
net asset value per share of the  Money Market Fund as computed for the  purpose
of  distribution and redemption  at $1.00 per share  taking into account current
market conditions  and  the Fund's  investment  objectives. At  such  reasonable
intervals  as they deem  appropriate in light of  current market conditions, the
Trustees will compare the results of  calculating the net asset value per  share
based on amortized cost with the results based
 
                                       28
<PAGE>
on available indications of market value. If a difference of more than 1/2 of 1%
occurs  between the  two methods of  valuation, the Trustees  will take whatever
steps they deem  necessary to  minimize any  material dilution  or other  unfair
results,  such as shortening the average  portfolio maturity, or realizing gains
or losses.
 
                           ORGANIZATION OF THE TRUST
 
    The Agreement and  Declaration of the  Trust ("Trust Declaration")  provides
that  all persons  extending credit  to, contracting  with or  having any claims
against the Trust  or a particular  Fund shall look  only to the  assets of  the
Trust  or particular Fund for payment under such credit, contract, or claim, and
neither the shareholders, Trustees, or  any of the Trust's officers,  employees,
or   agents  shall  be  personally  liable  thereof.  Under  Massachusetts  law,
shareholders  could,  under  certain  circumstances,  be  held  liable  for  the
obligations  of the Trust. The Trust Declaration, however, disclaims shareholder
liability for acts or obligations of the Trust and requires that notice of  such
disclaimer  be given in each Agreement, obligation or instrument entered into or
executed by  the Trust  or  the Trustees.  The  Trust Declaration  provides  for
indemnification  out  of a  Fund's  property for  all  loss and  expense  of any
shareholder of  that Fund  held liable  on account  of being  or having  been  a
shareholder. Thus, the risk of a shareholder incurring financial loss on account
of  shareholder liability is limited to circumstances in which the Fund of which
he or she was a shareholder would be unable to meet its obligations.
 
    Pursuant to the Trust Declaration,  a Trustee is liable  for his or her  own
willful  misfeasance, bad faith,  gross negligence or  reckless disregard of the
duties involved in the conduct of the  office of Trustee, but is not liable  for
errors  of judgment, mistakes of fact or  law, any act or omission in accordance
with the advice of counsel or other  experts with respect to the meaning of  the
Trust Declaration, or for failing to follow such advice.
 
    The  Trust Declaration provides that,  on any matter submitted  to a vote of
the shareholders, all  shares shall be  voted by individual  series, except  (1)
when required by the 1940 Act, shares shall be voted in the aggregate and not by
individual  series, and  (2) when the  Trustees have determined  that the matter
affects only the interests of one or more series, then only the shareholders  of
such  series shall be entitled to  vote thereon. Shares are freely transferable,
are entitled to dividends as declared by the Trustees and, on liquidation of the
Trust, shareholders are entitled  to receive their pro  data portion of the  net
assets  of  the Fund  of which  they hold  shares,  but not  of any  other Fund.
Shareholders have no preemptive rights.
 
    In the event that at any time less  than a majority of the Trustees then  in
office  were  elected by  the shareholders,  the Trustees  must promptly  call a
meeting of shareholders for the purpose of electing Trustees. Shareholders  will
be assisted in communicating with other shareholders in connection with removing
a Trustee as if Section 16(c) of the 1940 Act applied to the Trust.
 
    Matters  subject  to a  vote by  the  shareholders include  a change  in the
fundamental policies of the Trust, as  described in the Prospectus and the  SAI,
the  election  or  removal of  Trustees,  and  the approval  of  agreements with
investment advisers.  A majority,  for the  purposes of  voting by  shareholders
pursuant  to  the 1940  Act,  is 67%  or  more of  the  voting securities  of an
investment company present at  an annual or special  meeting of shareholders  if
50%  of  the  outstanding  voting  securities of  such  company  are  present or
represented by proxy or  more than 50% of  the outstanding voting securities  of
such company, whichever is less.

*Filed under Rule 24f-2 as part of Registrant's Rule 24f-2 Notice


Item 25.      PERSONS UNDER COMMON CONTROL WITH REGISTRANT

Registrant was organized by State Mutual Life Assurance Company of America, now
known as First Allmerica Financial Life Insurance Company ("First Allmerica")
primarily for the purpose of providing a vehicle for the investment of assets
received by various separate investment accounts ("Separate Accounts")
established by First Allmerica and life insurance company subsidiaries of First
Allmerica including Allmerica Life Insurance and Annuity Company ("Allmerica
Life").  The assets in such Separate Accounts are, under state law, assets of
the life insurance companies which have established such accounts.  Thus at any
time First Allmerica and its life insurance company subsidiaries will own such
of Registrant's outstanding shares as are purchased with Separate Account
assets; however, where required to do so, First Allmerica and its life insurance
company subsidiaries will vote such shares only in accordance with instructions
received from owners of the contracts pursuant to which sums are placed in such
Separate Accounts.

Item 26.      NUMBER OF HOLDERS OF SECURITIES

As of the date of this filing, the Registrant has ninety-six shareholders.  The
Allmerica Life Separate Account Va-A owns shares of the Growth Fund.  The
Allmerica Life Separate Account Va-B and Va-C own shares of the Investment Grade
Income Fund.  The Allmerica Life Separate Account Va-G and Va-H own shares of
the Money Market Fund. Five sub-accounts of the First Allmerica Separate Account
I own shares of the respective Funds. Eleven sub-accounts of the Allmerica Life
Separate Account Va-K invest in the respective Funds. Eleven sub-accounts of the
Allmerica Life VEL account, a separate account funding variable life insurance
policies, invest in the respective Funds.  Seven sub-accounts of the Allmerica
Life Select Separate Account, a separate account funding variable annuity
contracts and group variable annuity contracts, invest in the respective Funds.
Eleven sub-accounts of the Allmerica Life VEL II account, a separate account
funding variable life insurance policies, invest in the respective Funds.
Eleven sub-accounts of the Allmerica Life VEL INHEIRITAGE account, a separate
account funding variable life insurance policies, invest in the respective
Funds.  For policies and or contracts issued in the State of New York after
March 31, 1994, First Allmerica has replaced Allmerica Life for investment
purposes in the Registrant, consisting of eleven separate accounts of First
Allmerica Va-K accounts, a separate account funding variable annuity contracts
for their respective Funds. Seven First Allmerica Select Separate accounts, a
separate account funding variable annuity contracts and group variable annuity
contracts, invest in the respective Funds. Eleven sub-accounts of the First
Allmerica VEL II account, a separate account funding variable life insurance

Item 27.      INDEMNIFICATION

Article VIII of Registrant's Agreement and Declaration Trust, entitled
"Indemnification," is incorporated herein by reference to Exhibit 1 of this
Registration Statement.

Article III, Section 12 of the Bylaws of First Allmerica provides that, to the
extent permitted by law, First Allmerica shall indemnify and save harmless each
present or former Director, Officer, and Home Office employee against all
liabilities and reasonable expenses imposed upon or incurred by him in
connection with, or as a result of a judicially approved settlement of, any
action, suit, or proceeding brought or threatened by reason of his being or
having been a Director, Officer, or Home Office employee of First Allmerica or
being or having been a Director, Trustee, Officer, Home Office employee,
fiduciary or agent of any corporation, trust or partnership, plan or other
entity at the request of First Allmerica. First Allmerica may, in advance of
final disposition of any such action, suit, or proceeding, pay incurred expenses
upon receipt of an undertaking by the person indemnified to repay such payment
if he shall be adjudicated to be not entitled to indemnification.  No
indemnification shall be provided for any person with respect to any matter as
to which he shall have been adjudicated in any proceeding not to have acted in
good faith in the reasonable belief that his action was in the best interests of
First Allmerica.  Home Office employee means any employee, other than employees
eligible to participate in the career agents' pension plan.

UNDERTAKING PURSUANT TO RULE 484

Article VIII of Registrant's Agreement and Declaration of Trust provides that
each of its Trustees and each Officer ( and his heirs, executors, and
administrators) may be indemnified against all liabilities and expenses arising
out of the defense or disposition of any action, suit, or other proceeding in
which such person may be or may have been involved by reason of being or having
been such a Trustee or Officer, except with respect to any matter as to which
such person shall have been finally adjudicated not to have acted in good faith
in the reasonable belief that such action was in the best interests of
Registrant, and except that no person shall be indemnified against any liability
to Registrant or to its shareholders to which such person otherwise would be
subject by reason of willful misfeasance, bad faith, gross negligence or
reckless disregard of the duties involved in the conduct of such person's
office.

Insofar as indemnification for liability arising under the 1933 Act may be
permitted to Trustees, Officers and Controlling Persons of Registrant pursuant
to the foregoing provisions, or otherwise, Registrant has been advised that, in
the opinion of the Securities  and Exchange Commission, such indemnification is
against public policy as expressed in the 1933 Act and is, therefore,
unenforceable.  In the event that a claim for indemnification against such
liabilities (other than the payment by Registrant of expenses incurred or paid
by a Trustee, officer or controlling person of Registrant in the successful
defense of any action, suit or proceeding) is asserted by such Trustee, Officer
or Controlling Person in connection with the securities being registered,
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the 1933 Act and will be governed by the final adjudication of such
issue.

                                SUB-ADVISER AGREEMENT

Sub-Adviser Agreement executed as of May 1, 1994 between ALLMERICA INVESTMENT
MANAGEMENT COMPANY, INC., 440 Lincoln Street, Worcester, Massachusetts 01653
(the "Manager"), and BANK OF IRELAND ASSET MANAGEMENT LIMITED, with a principal
place of business at 26 Fitzwilliam Place, Dublin 2, Ireland, (the
"Sub-Adviser").

   WITNESSETH:

   That in consideration of the mutual covenants herein contained, it is agreed
as follows:

1. SERVICES TO BE RENDERED BY SUB-ADVISER TO THE TRUST

   (a) Subject always to the control of the Trustees of Allmerica Investment
Trust (the "Trust"), a Massachusetts business trust, the Sub-Adviser, at its
expense, will furnish continuously an investment program for the following
series of shares of the Trust: SELECT INTERNATIONAL EQUITY FUND and such other
series of shares as the Trust, the Manager and the Sub-Adviser may from time to
time agree on (the "Fund"). The Sub-Adviser will make investment decisions on
behalf of the Fund and place all orders for the purchase and sale of portfolio
securities. In the performance of its duties, the Sub-Adviser will comply with
the provisions of the Agreement and Declaration of Trust and Bylaws of the Trust
and the objectives and policies of the Funds, as set forth in the current
Registration Statement of the Trust filed with the Securities and Exchange
Commission ("SEC") and any applicable federal and state laws, and will comply
with other policies which the Trustees of the Trust (the "Trustees") or the
Manager, as the case may be, may from time to time determine. The Sub-Adviser
shall make its officers and employees available to the Manager from time to time
at reasonable times to review investment policies of the Fund and to consult
with the Manager regarding the investment affairs of the Fund. In the
performance of its duties hereunder, the Sub-Adviser is and shall be an
independent contractor and, unless otherwise expressly provided or authorized,
shall have no authority to act for or represent the Trust in any way or
otherwise be deemed to be an agent of the Trust.

   (b) The Sub-Adviser, at its expense, will furnish (i) all necessary
investment and management facilities, including salaries of personnel required
for it to execute its duties faithfully, and (ii) administrative facilities,
including clerical personnel and equipment necessary for the efficient conduct
of the investment affairs of the Fund (excluding pricing and bookkeeping
services).

   (c) The Sub-Adviser shall place all orders for the purchase and sale of
portfolio investments for the Fund with issuers, brokers or dealers selected by
the Sub-Adviser which may include brokers or dealers affiliated with the
Sub-Adviser. In the selection of such brokers or dealers and the placing of such
orders, the Sub-Adviser always shall seek best execution (except to the extent
permitted by the next sentence hereof), which is to place portfolio transactions
where the Fund can obtain the most favorable combination of price and execution
services in particular transactions or provided on a continuing basis by a
broker or dealer, and to deal directly with a principal market maker in
connection with over-the-counter transactions, except when it is believed that
best execution is obtainable elsewhere. Subject to such policies as the Trustees
may determine, the Sub-Adviser shall not be deemed to have acted unlawfully or
to have breached any duty created by this Agreement or otherwise solely by
reason of its having caused the Trust to pay a broker or dealer that provides
brokerage and research services an amount of commission for effecting a
portfolio investment transaction in excess of the amount of commission another
broker or dealer would have charged for effecting that transaction, if the
Sub-Adviser determines in good faith that such excess amount of commission was
reasonable in relation to the value of the brokerage and research services
provided by such broker or dealer, viewed in terms of either that particular
transaction or the overall responsibilities of the Sub-Adviser and its
affiliates with respect to the Trust and to other clients of the Sub-Adviser as
to which the Sub-Adviser or any affiliate

<PAGE>

of the Sub-Adviser exercises investment discretion.

2. OTHER AGREEMENTS

   It is understood that any of the shareholders, Trustees, officers and
employees of the Trust may be a shareholder, partner, director, officer or
employee of, or be otherwise interested in, the SubAdviser, and in any person
controlled by or under common control with the Sub-Adviser, and that the
Sub-Adviser and any person controlled by or under common control with the
Sub-Adviser may have an interest in the Trust. It is also understood that the
Sub-Adviser and persons controlled by or under common control with the
Sub-Adviser have and may have advisory, management service or other contracts
with other organizations and persons, and may have other interests and
businesses.

3. COMPENSATION TO BE PAID BY THE MANAGER TO THE SUB-ADVISER

   The Manager will pay to the Sub-Adviser as compensation for the
Sub-Adviser's services rendered, a fee, determined as described in Schedule A
which is attached hereto and made a part hereof. Such fee shall be paid by the
Manager and not by the Trust.

4. AMENDMENTS OF THIS AGREEMENT

   This Agreement (including Schedule A hereto) shall not be amended as to any
Fund unless such amendment is approved at a meeting by the affirmative vote of a

                                SUB-ADVISER AGREEMENT


 Sub-Adviser Agreement executed as of June 30, 1995 between Allmerica Investment
Management Company, Inc. (the "Manager") and David L. Babson & Co. Inc. (the
"Sub-Adviser").

  Witnesseth:

  That in consideration of the mutual covenants herein contained, it is agreed
as follows:

1. SERVICES TO BE RENDERED BY SUB-ADVISER TO THE TRUST

 (a) Subject always to the control of the Trustees of Allmerica Investment Trust
(the "Trust"), a Massachusetts business trust, the Sub-Adviser, at its expense,
will furnish continuously an investment program for the following series of
shares of the Trust: the SMALL CAP VALUE FUND and such other series of shares as
the Trust, the Manager and the Sub-Adviser may from time to time agree on
(together, the "Funds"). The Sub-Adviser will make investment decisions on
behalf of the Funds and place all orders for the purchase and sale of portfolio
securities. In the performance of its duties, the Sub-Adviser will comply with
the provisions of the Agreement and Declaration of Trust and Bylaws of the Trust
and the objectives and policies of the Fund, as set forth in the current
Registration Statement of the Trust filed with the Securities and Exchange
Commission ("SEC") and any applicable federal and state laws, and will comply
with other policies which the Trustees of the Trust (the "Trustees") or the
Manager, as the case may be, may from time to time determine and which are
furnished to the Sub-Adviser. The Sub-Adviser shall make its officers and
employees available to the Manager from time to time at reasonable times to
review investment policies of the Fund and to consult with the Manager regarding
the investment affairs of the Funds. In the performance of its duties hereunder,
the Sub-Adviser is and shall be an independent contractor and, unless otherwise
expressly provided or authorized, shall have no authority to act for or
represent the Trust in any way or otherwise be deemed to be an agent of the
Trust.

 (b) The Sub-Adviser shall place all orders for the purchase and sale of
portfolio investments for the Fund with issuers, brokers or dealers selected by
the SubAdviser which may include brokers or dealers affiliated with the
Sub-Adviser. In the selection of such brokers or dealers and the placing of such
orders, the Sub-Adviser always shall seek best execution, (except to the extent
permitted by the next sentence hereof) which is to place portfolio transactions
where the Fund can obtain the most favorable combination of price and execution
services in particular transactions or provided on a continuing basis by a
broker or dealer, and to deal directly with a principal market maker in
connection with over-the-counter transactions, except when it is believed that
best execution is obtainable elsewhere. Subject to such policies as the Trustees
may determine, the Sub-Adviser shall not be deemed to have acted unlawfully or
to have breached any duty created by this Agreement or otherwise solely by
reason of its having caused the Trust to pay a broker or dealer that provides
brokerage and research services an amount of commission for effecting a
portfolio investment transaction in excess of the amount of commission another
broker or dealer would have charged for effecting that transaction, if the
Sub-Adviser determines in good faith that such excess amount of commission was
reasonable in relation to the value of the brokerage and research services
provided by such broker or dealer, viewed in terms of either that particular
transaction or the overall responsibilities of the Sub-Adviser and its
affiliates with respect to the Trust and to other clients of the Sub-Adviser as
to which Sub-Adviser or any affiliate of the Sub-Adviser exercises investment
discretion.

<PAGE>


2. OTHER AGREEMENTS

 It is understood that any of the shareholders, Trustees, officers and employees
of the Trust may be a shareholder, partner, director, officer or employee of, or
be otherwise interested in, the Sub-Adviser, and in any person controlled by or
under common control with the Sub-Adviser, and that the Sub-Adviser and any
person controlled by or under common control with the Sub-Adviser may have an
interest in the Trust. It is also understood that the Sub-Adviser and persons
controlled by or under common control with the Sub-Adviser have and may have
advisory, management service or other contracts with other organizations and
persons, and may have other interests and businesses.

3. COMPENSATION TO BE PAID BY THE MANAGER TO THE SUB-ADVISER

 The Manager will pay to the Sub-Adviser as compensation for the Sub-Adviser's
services rendered a fee, determined as described in Schedule A which is attached
hereto and made a part hereof. Such fee shall be paid by the Manager and not by
the Trust.

4. AMENDMENTS OF THIS AGREEMENT

to any Fund unless such amendment is approved at a meeting by the affirmative
vote of a majority of the outstanding voting securities of the Fund, and by the
vote, cast in person at a meeting called for the purpose of voting on such
approval, of a majority of the Trustees who are not interested persons of the
Trust, or of the Manager or of the Sub-Adviser.

5. EFFECTIVE PERIOD AND TERMINATION OF THIS AGREEMENT

 This Agreement shall be effective as of the date executed, and shall remain in
full force and effect as to each Fund continuously thereafter, until terminated
as provided below:

  A. Unless terminated as herein provided, this Agreement shall remain in full
force and effect until May 30, 1996, and shall continue in full force and effect
for successive periods of one year thereafter, but only so long as such
continuance is specifically approved at least annually (i) by the Trustees or by

Fund, and (ii) by a vote of a majority of the Trustees who are not interested
persons of the Trust or of the Manager or of any Sub-Adviser, by vote cast in

however, that if the continuance of this Agreement is submitted to the
shareholders of a Fund for their approval and such shareholders fail to approve
such continuance of this Agreement as provided herein, the Sub-Adviser may
continue to serve hereunder as the Sub-Adviser to such Funds in a manner
consistent with the Investment Company Act of 1940, as amended ("1940 Act") and
the rules and regulations thereunder.

  B. This Agreement may be terminated as to any Fund without the payment of any
penalty by the Manager, subject to the approval of the Trustees, by vote of the
Trustees, or by vote of a majority of the outstanding voting securities of such
Fund at any annual or special meeting or by the Sub-Adviser on sixty days'

Agreement shall have terminated for any reason.

                                SUB-ADVISER AGREEMENT


Sub-Adviser Agreement executed as of February 15, l995 between ALLMERICA
INVESTMENT MANAGEMENT COMPANY, INC. (the "Manager"), and PROVIDENT INVESTMENT
COUNSEL, INC. ("PIC") (the "Sub-Adviser").

  Witnesseth:

  That in consideration of the mutual covenants herein contained, it is agreed
as follows:

1. SERVICES TO BE RENDERED BY SUB-ADVISER TO THE TRUST

   (a) Subject always to the control of the Trustees of Allmerica Investment
Trust (the "Trust"), a Massachusetts business trust, the Sub-Adviser, at its
expense, will furnish continuously an investment program for the following
series of shares of the Trust: SELECT GROWTH FUND and such other series of
shares as the Trust, the Manager and the Sub-Adviser may from time to time agree
on (together, the "Funds"). The Sub-Adviser will make investment decisions on
behalf of each of the Funds and place all orders for the purchase and sale of
portfolio securities. In the performance of its duties, the Sub-Adviser will
comply with the provisions of the Agreement and Declaration of Trust and Bylaws
of the Trust and the objective and policies of each of the Funds, as set forth
in the current Registration Statement of the Trust filed with the Securities and
Exchange Commission ("SEC") and any applicable federal and state laws, and will
comply with other policies which the Trustees of the Trust (the "Trustees") or
the Manager, as the case may be, may from time to time determine in writing. The
Sub-Adviser shall make its officers and employees available to the Manager from
time to time at reasonable times to review investment policies of the Funds and
to consult with the Manager regarding the investment affairs of the Funds. In
the performance of its duties hereunder, the, Sub-Adviser is and shall be an
independent contractor and, unless otherwise expressly provided or authorized,
shall have no authority to act for or represent the trust in any way or
otherwise be deemed to be an agent of the Trust.

  (b) The Sub-Adviser, at its expense, will furnish (i) all necessary
investment and management facilities, including salaries of personnel required
for it to execute its duties faithfully, and (ii) administrative facilities,
including clerical personnel and equipment necessary for the efficient conduct
of the investment affairs of each of the Funds (excluding pricing and
bookkeeping services).

  (c) The Sub-Adviser shall place all orders for the purchase and sale of
portfolio investments for each Fund with issuers, brokers or dealers selected by
the Sub-Adviser which may include brokers or dealers affiliated with the
Sub-Adviser. In the selection of such brokers or dealers and the placing of such
orders, the Sub-Adviser always shall seek best execution (except to the extent
permitted by the next sentence hereof), which is to place portfolio transactions
where each Fund can obtain the most favorable combination of price and execution
services in particular transactions or provided on a continuing basis by a
broker or dealer, and to deal directly with a principal market maker in
connection with over-the-counter transactions, except when it is believed that
best execution is obtainable elsewhere. Subject to such policies as the Trustees
may determine, the SubAdviser shall not be deemed to have acted unlawfully or to
have breached any duty created by this Agreement or otherwise solely by reason
of its having caused the Trust to pay a broker or dealer that provides brokerage
and research services an amount of commission for effecting a portfolio
investment transaction in excess of the amount of commission another broker or
dealer would have charged for effecting that transaction, if the Sub-Adviser
determines in good faith that such excess

<PAGE>


amount of commission was reasonable in relation to the value of the brokerage
and research services provided by such broker or dealer, viewed in terms of
either that particular transaction or the overall responsibilities of the
Sub-Adviser and its affiliates with respect to the Trust and to other clients of
the Sub-Adviser as to which the Sub-Adviser or any affiliate of the Sub-Adviser
exercises investment discretion.

  (d) The Sub-Adviser shall not be obligated to pay any expenses of or for a
Fund not expressly assumed by the Sub-Adviser pursuant to this Section 1.

2. OTHER AGREEMENTS

   It is understood that any of the shareholders, Trustees, officers and
employees of the Trust may be a shareholder, partner, director, officer or
employee of, or be otherwise interested in, thc SubAdviser, and in any person
controlled by or under common control with the Sub-Adviser, and that the
Sub-Adviser and any person controlled by or under common control with the
Sub-Adviser may have an interest in the Trust. It is also understood that the
Sub-Adviser and persons controlled by or under common control with the
Sub-Adviser have and may have advisory, management service or other contracts
with other organizations and persons, and may have other interests and
businesses.

3. COMPENSATION TO BE PAID BY THE MANAGER TO THE SUB-ADVISER

   The Manager will pay to the Sub-Adviser as compensation for the Sub-Adviser's
services rendered and for the expenses borne by the Sub-Adviser pursuant to
Section 1, a fee, determined as described in Schedule A which is attached hereto
and made a part hereof. Such fee shall be paid by the Manager and not by the
Trust.

majority of the Trustees who are not interested persons of the Trust or of the
Manager or of the Sub-Adviser.


5. EFFECTIVE PERIOD AND TERMINATION OF THIS AGREEMENT

   This Agreement shall be effective as of February 15, 1995, and shall remain
in full force and effect until May 31, 1995, as to each Fund continuously
thereafter, until terminated as provided below.

force and effect until May 31, 1995, and shall continue in full force and effect
for successive periods of one year thereafter, but only so long as each such
continuance is specifically approved annually (i) by the Trustees or by the

Fund, and (ii) by a vote of a majority of the Trustees who are not interested
persons of the Trust or of the Manager or of any Sub-Adviser, by vote cast in
person at a meeting called for the purpose of voting on such approval; provided,
however, that if the continuance of this Agreement is submitted to the
shareholders of a Fund for their approval and such shareholders fail to approve
such continuance of this Agreement as provided herein, the Sub-Adviser may
continue to serve hereunder in a manner consistent with the Investment Company
Act of 1940, as amended

<PAGE>

(" 1940 Act") and the rules and regulations thereunder.

any penalty by the Manager, by vote of the Trustees, subject to the approval of
the Trustees, or by vote of a majority of the outstanding voting securities of
such Fund at any annual or special meeting or by the Sub-Adviser on sixty days'
written notice.

7. NONLIABILITY OF SUB-ADVISER

   In the absence of willful misfeasance, bad faith or gross negligence on the
part of the SubAdviser, or reckless disregard of its obligations and duties
hereunder, the Sub-Adviser shall not be subject to any liability to the Trust,

             Property, as the same become payable and credit the same to the
             appropriate Account;

                    (b)    present for payment all Securities held in an
             Account which are called, redeemed or retired or otherwise become

             temporary securities for those in definitive form and the exchange
             of warrants, or other documents of entitlement to securities, for
             the Securities themselves) and (ii) when notification of a tender
             or exchange offer (other than ministerial exchanges described in
             (i) above) is received for an Account, endeavor to receive
             Instructions, provided that if such Instructions are not received
             in time for the Custodian to take timely action, no action shall
             be taken with respect thereto;

                    (d)    whenever notification of a rights entitlement or a
             fractional interest resulting from a rights issue, stock dividend
             or stock split is received for an Account and such rights
             entitlement or fractional interest bears an expiration date, if
             after endeavoring to obtain Instructions such Instructions are not
             received in time for the Custodian to take timely action or if
             actual notice of such actions was received too late to seek
             Instructions, sell in the discretion of the Custodian (which sale
             the Customer hereby authorizes the Custodian to make) such rights
             entitlement or fractional interest and credit the Account with the
             net proceeds of such sale;

             other certificates as may be required to obtain the payment of
             income from the Property in such Account;

                    (f)    pay for each Account, any and all taxes and levies

             similar income on the Property in such Account by any governmental
             authority.  In the event there is insufficient Cash available in
             such Account to pay such taxes and levies, the Custodian shall
             notify the Customer of the amount of the shortfall and the
             Customer, at its option, may deposit additional Cash in such
             Account or take steps to have sufficient Cash available.  The
             Customer agrees, when and if requested by the Custodian and
             required in connection

                                          2

subsidiaries, a non-U.S. branch or majority-owned subsidiary of a U.S. bank or a
non-U.S. bank or trust company, acting as custodian (individually, a "non-U.S.
Subcustodian"; U.S. Subcustodians and non-U.S. Subcustodians, collectively,
"Subcustodians"), or a non-U.S. depository or clearing agency or system in which
the Custodian or any Subcustodian participates (individually, a "non-U.S.
Securities System"; U.S. Securities System and non-U.S. Securities System,
collectively, Securities System"), PROVIDED that in each case in which a U.S.
Subcustodian or U.S. Securities System is employed, each such Subcustodian or
Securities System shall have been approved by Instructions; PROVIDED FURTHER
that in each case in which a non-U.S. Subcustodian or non-U.S. Securities System
is employed, (a) such Subcustodian or Securities System either is (i) a
"qualified U.S. bank" as defined by Rule 17f-5 under the 1940 Act ("Rule 17f-5")
or (ii) an "eligible foreign custodian" within the meaning of Rule 17f-5 or such
Subcustodian or Securities System is the subject of an order granted by the U.S.
Securities and Exchange Commission ("SEC") exempting such agent or the
subcustody arrangements thereto from all or part of the provisions of Rule 17f-5
and (b) the agreement between the Custodian and such non-U.S. Subcustodian has
been approved by Instructions; it being understood that the Custodian shall have
no liability or responsibility for determining whether the approval of any
Subcustodian or Securities System has been proper under the 1940 Act or any rule
or regulation thereunder.

             Upon receipt of Instructions, the Custodian agrees to cease the
employment of any Subcustodian or Securities System with respect to the
Customer, and if desirable and practicable, appoint a replacement subcustodian
or securities system in accordance with the provisions of this Section.  In
addition, the Custodian may, at any time in its discretion, upon written
notification to the Customer, terminate the employment of any Subcustodian or
Securities System.

             Upon request of the Customer, the Custodian shall deliver to the
Customer annually a certificate stating:  (a) the identity of each non-U.S.
Subcustodian and non-U.S. Securities System then acting on behalf of the
Custodian and the name and address of the governmental agency or other
regulatory authority that supervises or regulates such non-U.S Subcustodian and
non-U.S. Securities System; (b) the countries in which each non-U.S.
Subcustodian or non-U.S. Securities System is located; and (c) so long as Rule

Systems similar in kind

                                          3

<PAGE>


and scope as that furnished to the Customer in connection with the initial
approval of this Agreement.  Custodian agrees to promptly notify the Customer
if, in the normal course of its custodial activities, the Custodian has reason
to believe that any non-U.S. Subcustodian or non-U.S. Securities System has
ceased to be a qualified U.S. bank or an eligible foreign custodian each within
the meaning of Rule 17f-5 or has ceased to be subject to an exemptive order from
the SEC.

             8.     RECORDS, OWNERSHIP OF PROPERTY, STATEMENTS, OPINIONS OF
INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS.

             (a)  The ownership of the Property whether Securities, Cash and/or
other property, and whether held by the Custodian or a Subcustodian or in a
Securities System as authorized herein, shall be clearly recorded on the
Custodian's books as belonging to the appropriate Account and not for the
Custodian's own interest.  The Custodian shall keep accurate and detailed
accounts of all investments, receipts, disbursements and other transactions for
each Account.  All accounts, books and records of the Custodian relating thereto
shall be open to inspection and audit at all reasonable times during normal
business hours by any person designated by the Customer.  All such accounts
shall be maintained and preserved in the form reasonably requested by the
Customer.  The Custodian will supply to the Customer from time to time, as
mutually agreed upon, a statement in respect to any Property in an Account held
by the Custodian or by a Subcustodian.  In the absence of the filing in writing
with the Custodian by the Customer of exceptions or objections to any such
statement within sixty (60) days of the mailing thereof, the Customer shall be
deemed to have approved such statement and in such case or upon written approval
of the Customer of any such statement, such statement shall be presumed to be
for all purposes correct with respect to all information set forth therein.

             (b)   The Custodian shall take all reasonable action as the
Customer may request to obtain from year to year favorable opinions from the
Customer's independent certified public accountants with respect to the

the SEC and with respect to any other requirements of the SEC.

             (c)  At the request of the Customer, the Custodian shall deliver
to the Customer a written report prepared by the Custodian's independent
certified public accountants with respect to the services provided by the
Custodian under this Agreement, including, without limitation, the Custodian's

sufficient scope and in sufficient detail as may reasonably be required by the
Customer and as may reasonably be obtained by the Custodian.

             (d) The Customer may elect to participate in any of the electronic
on-line service and communications systems offered by the Custodian which can
provide the Customer, on a daily basis, with the ability to view on-line or to
print on hard copy various reports of Account activity and of

                                          5

<PAGE>

Securities and/or Cash being held in any Account.  To the extent that such
service shall include market values of Securities in an Account, the Customer
hereby acknowledges that the Custodian now obtains and may in the future obtain
information on such values from outside sources that the Custodian considers to
be reliable and the Customer agrees that the Custodian (i) does not verify or
represent or warrant either the reliability of such service nor the accuracy or
completeness of any such information furnished or obtained by or through such
service and (ii) shall be without liability in selecting and utilizing such
service or furnishing any information derived therefrom.

             9.     HOLDING OF SECURITIES, NOMINEES, ETC.  Securities in an
Account which are held by the Custodian or any Subcustodian may be held by such
entity in the name of the Customer, on behalf of a Portfolio, in the Custodian's
or Subcustodian's name, in the name of the Custodian's or Subcustodian's
nominee, or in bearer form.  Securities that are held by a Subcustodian or which
are eligible for deposit in a Securities System as provided above may be
maintained with the Subcustodian or the Securities System in an account for the
Custodian's or Subcustodian's customers, unless prohibited by law, rule, or
regulation.  The Custodian or Subcustodian, as the case may be, may combine
certificates representing Securities held in an Account with certificates of the
same issue held by it as fiduciary or as a custodian.  In the event that any
Securities in the name of the Custodian or its nominee or held by a Subcustodian
and registered in the name of such Subcustodian or its nominee are called for
partial redemption by the issuer of such Security, the Custodian may, subject to
the rules or regulations pertaining to allocation of any Securities System in
which such Securities have been deposited, allot, or cause to be allotted, the
called portion of the respective beneficial holders of such class of security in
any manner the Custodian deems to be fair and equitable.

             10.    PROXIES, ETC.  With respect to any proxies, notices,
reports or other communications relative to any of the Securities in any
Account, the Custodian shall perform such services and only such services
relative thereto as are (i) set forth in Section 3 of this Agreement, (ii)
described in Exhibit B attached hereto (as such service therein described may be
in effect from time to time) (the "Proxy Service") and (iii) as may otherwise be
agreed upon between the Custodian and the Customer.  The liability and
responsibility of the Custodian in connection with the Proxy Service referred to
in (ii) of the immediately preceding sentence and in connection with any
additional services which the Custodian and the Customer may agree upon as
provided in (iii) of the immediately preceding sentence shall be as set forth in
the description of the Proxy Service and as may be agreed upon by the Custodian
and the Customer in connection with the furnishing of any such additional
service and shall not be affected by any other term of this Agreement.  Neither
the Custodian nor its nominees or agents shall vote upon or in respect of any of
the Securities in an Account, execute any form of proxy to vote thereon, or give
any consent or take any action (except as provided in Section 3) with respect
thereto except upon the receipt of Instructions relative thereto.

             11.    SEGREGATED ACCOUNT.  To assist the Customer in complying
with the requirements of the 1940 Act and the rules and regulations thereunder,
the Custodian shall, upon receipt of Instructions, establish and maintain a
segregated account or accounts on its books for and on behalf of a Portfolio.

             12.    SETTLEMENT PROCEDURES. Securities will be transferred,
exchanged or delivered by the Custodian or a Subcustodian upon receipt by the
Custodian of Instructions which include all information required by the
Custodian.  Settlement and payment for Securities received for an Account and
delivery of Securities out of such Account may be effected in accordance with
the customary or established securities trading or securities processing
practices and procedures in the jurisdiction or market in which the transaction
occurs, including, without limitation, delivering Securities to the

                                          6

<PAGE>

purchaser thereof or to a dealer therefor (or an agent for such purchaser or
dealer) against a receipt with the expectation of receiving later payment for
such Securities from such purchaser or dealer, as such practices and procedures
may be modified or supplemented in accordance with the standard operating
procedures of the Custodian in effect from time to time for that jurisdiction or
market.  The Custodian shall not be liable for any loss which results from
effecting transactions in accordance with the customary or established
securities trading or securities processing practices and procedures in the
applicable jurisdiction or market, so long as the Custodian used reasonable care
in effecting such transactions.

             Notwithstanding that the Custodian may settle purchases and sales
against, or credit income to, an Account, on a contractual basis, as outlined in
the Investment Manager User Guide provided to the Customer by the Custodian, the
Custodian may, at its sole option, reverse such credits or debits to the
appropriate Account in the event that the transaction does not settle, or the
income is not received in a timely manner, and the Customer agrees to hold the
Custodian harmless from any losses which may result therefrom.

             Except as otherwise may be agreed upon by the parties hereto, the
Custodian shall not be required to comply with Instructions to settle the
purchase of any Securities for an Account unless there is sufficient Cash in
such Account at the time or to settle the sale of any Securities in such Account
unless such Securities are in deliverable form.  Notwithstanding the foregoing,
if the purchase price of such securities exceeds the amount of Cash in an
Account at the time of settlement of such purchase, the Custodian may, in its
sole discretion, but in no way shall have any obligation to, permit an overdraft
in such Account in the amount of the difference solely for the purpose of
facilitating the settlement of such purchase of securities for prompt delivery
for such Account.  The Customer agrees to immediately repay the amount of any
such overdraft in the ordinary course of business and further agrees to
indemnify and hold the Custodian harmless from and against any and all losses,
costs, including, without limitation the cost of funds, and expenses incurred in
connection with such overdraft.  The Customer agrees that it will not use the
Account to facilitate the purchase of securities without sufficient funds in the
Account (which funds shall not include the proceeds of the sale of the purchased
securities).

             13.  PERMITTED TRANSACTIONS.  The Customer agrees that it will
cause transactions to be made pursuant to this Agreement only upon Instructions
in accordance Section 14 and only for the purposes listed below.

             (a)  In connection with the purchase or sale of Securities at

of the National Association of Securities Dealers, Inc., relating to compliance
with the rules of The Options Clearing Corporation, the Commodities Futures
Trading Commission and of any registered national securities exchange, or of any
similar organization or organizations, regarding escrow or other arrangements in
connection with transactions by the Customer.

             (l)  For release of Securities to designated brokers under covered
call options, provided, however, that such Securities shall be released only
upon payment to the Custodian of monies for the premium due and a receipt for
the Securities which are to be held in escrow.  Upon exercise of the option, or
at expiration, the Custodian will receive the Securities previously deposited
from broker.  The Custodian will act strictly in accordance with Instructions in
the delivery of Securities to be held in escrow and will have no responsibility
or liability for any such Securities which are not returned promptly when due
other than to make proper request for such return.

             (m)  For spot or forward foreign exchange transactions to
facilitate security trading or receipt of income from Securities related
transactions.

             (n)  Upon the termination of this Agreement as set forth in
Section 20.
             (o)  For other proper purposes.

  The Customer agrees that the Custodian shall have no obligation to verify the
purpose for which a transaction is being effected.

             14.  INSTRUCTIONS.  The term "Instructions" means instructions
from the Customer in respect of any of the Custodian's duties hereunder which
have been received by the Custodian at its address set forth in Section 21 below
(i) in writing (including, without limitation, facsimile transmission) or by
tested telex signed or given by such one or more person or persons as the
Customer shall have from time to time authorized in writing to give the
particular class of Instructions in question and whose name and (if applicable)
signature and office address have been filed with the Custodian, or (ii) which
have been transmitted electronically through an electronic on-line service and

                                          8

<PAGE>

communications system offered by the Custodian or other electronic instruction
system acceptable to the Custodian, or (iii) a telephonic or oral communication
by one or more persons as the Customer shall have from time to time authorized
to give the particular class of Instructions in question and whose name has been
filed with the Custodian; or (iv) upon receipt of such other form of
instructions as the Customer may from time to time authorize in writing and
which the Custodian has agreed in writing to accept.  Instructions in the form
of oral communications shall be confirmed by the Customer by tested telex or
writing in the manner set forth in clause (i) above, but the lack of such
confirmation shall in no way affect any action taken by the Custodian in
reliance upon such oral instructions prior to the Custodian's receipt of such
confirmation.  Instructions may relate to specific transactions or to types or
classes of transactions, and may be in the form of standing instructions.

             The Custodian shall have the right to assume in the absence of
notice to the contrary from the Customer that any person whose name is on file
with the Custodian pursuant to this Section has been authorized by the Customer
to give the Instructions in question and that such authorization has not been
revoked.  The Custodian may act upon and conclusively rely on, without any
liability to the Customer or any other person or entity for any losses resulting
therefrom, any Instructions reasonably believed by it to be furnished by the
proper person or persons as provided above.

             15.  STANDARD OF CARE.  The Custodian shall be responsible for the
performance of only such duties as are set forth herein or contained in
Instructions given to the Custodian which are not  contrary to the provisions of
this Agreement.  The Custodian will use reasonable care with respect to the
safekeeping of Property in each Account and in carrying out its obligations
under this Agreement.  So long as and to the extent that it has exercised
reasonable care, the Custodian shall not be responsible for the title, validity
or genuineness of any Property or other property or evidence of title thereto
received by it or delivered by it pursuant to this Agreement and shall be held
harmless in acting upon, and may conclusively rely on, without liability for any
loss resulting therefrom, any notice, request, consent, certificate or other
instrument reasonably believed by it to be genuine and to be signed or furnished
by the proper party or parties, including, without limitation, Instructions, and
shall be indemnified by the Customer for any losses, damages, costs and expenses
(including, without limitation, the reasonable fees and expenses of counsel)
incurred by the Custodian and arising out of action taken or omitted with
reasonable care by the Custodian hereunder or under any Instructions.  The
Custodian shall be liable to the Customer for any act or omission to act of any
Subcustodian to the same extent as if the Custodian committed such act itself.
With respect to a Securities System, the Custodian shall only be responsible or
liable for losses arising from employment of such Securities System caused by
the Custodian's own failure to exercise reasonable care.  In the event of any
loss to the Customer by reason of the failure of the Custodian or a Subcustodian
to utilize reasonable care, the Custodian shall be liable to the Customer to the
extent of the Customer's actual damages at the time such loss was discovered
without reference to any special conditions or circumstances.  In no event shall
the Custodian be liable for any consequential or special damages.  The Custodian
shall be entitled to rely, and may act, on advice of counsel (who may be counsel
for the Customer) on all matters and shall be without liability for any action
reasonably taken or omitted pursuant to such advice.

             In the event the Customer subscribes to an electronic on-line
service and communications system offered by the Custodian, the Customer shall
be fully responsible for the security of the Customer's connecting terminal,
access thereto and the proper and authorized use thereof and the initiation and
application of continuing effective safeguards with respect thereto and agree to
defend and indemnify the Custodian and hold the Custodian harmless from and
against any and all losses, damages, costs and expenses (including the
reasonable fees and expenses of counsel)

                                          9

<PAGE>

incurred by the Custodian as a result of any improper or unauthorized use of
such terminal by the Customer or by any others.

             All collections of funds or other property paid or distributed in
respect of Securities in an Account, including funds involved in third-party
foreign exchange transactions, shall be made at the risk of the Customer.


             Subject to the exercise of reasonable care, the Custodian shall
have no liability for any loss occasioned by delay in the actual receipt of
notice by the Custodian or by a Subcustodian of any payment, redemption or other
transaction regarding Securities in each Account in respect of which the
Custodian has agreed to take action as provided in Section 3 hereof.  The
Custodian shall not be liable for any loss resulting from, or caused by, or
resulting from acts of governmental authorities (whether de jure or de facto),
including, without limitation, nationalization, expropriation, and the
imposition of currency restrictions; devaluations of or fluctuations in the
value of currencies; changes in laws and regulations applicable to the banking
or securities industry; market conditions that prevent the orderly execution of
securities transactions or affect the value of Property; acts of war, terrorism,
insurrection or revolution; strikes or work stoppages; the inability of a local
clearing and settlement system to settle transactions for reasons beyond the
control of the Custodian; hurricane, cyclone, earthquake, volcanic eruption,
nuclear fusion, fission or radioactivity, or other acts of God.

             The Custodian shall have no liability in respect of any loss,
damage or expense suffered by the Customer, insofar as such loss, damage or
expense arises from the performance of the Custodian's duties hereunder by
reason of the Custodian's reliance upon records that were maintained for the
Customer by entities other than the Custodian prior to the Custodian's
employment under this Agreement.

             The provisions of this Section shall survive termination of this
Agreement.

             16.    INVESTMENT LIMITATIONS AND LEGAL OR CONTRACTUAL
RESTRICTIONS OR REGULATIONS.  The Custodian shall not be liable to the Customer
and the Customer agrees to indemnify the Custodian and its nominees, for any
loss, damage or expense suffered or incurred by the Custodian or its nominees
arising out of any violation of any investment restriction or other restriction
or limitation applicable to the Customer or any Portfolio pursuant to any
contract (other than contracts to which the Custodian is a party) or any law or
regulation.  The provisions of this Section shall survive termination of this
Agreement.

             17.    FEES AND EXPENSES.  The Customer agrees to pay to the
Custodian such compensation for its services pursuant to this Agreement as may
be mutually agreed upon in writing from time to time and the Custodian's
reasonable out-of-pocket or incidental expenses in connection with the
performance of this Agreement, including (but without limitation) reasonable
legal fees as described herein and/or deemed necessary in the judgment of the
Custodian to keep safe or protect the Property in the Account.  The initial fee
schedule is attached hereto as Exhibit C.  The Customer hereby agrees to hold
the Custodian harmless from any liability or loss resulting from any taxes or
other governmental charges, and any expense related thereto, which may be
imposed, or assessed with respect to any Property in an Account and also agrees
to hold the Custodian, its Subcustodians, and their respective nominees harmless
from any liability as a record holder of Property in such Account. The
provisions of this Section shall survive the termination of this Agreement.

                                          10

<PAGE>

             18.    TAX RECLAIMS.  With respect to withholding taxes deducted
and which may be deducted from any income received from any Property in an
Account, the Custodian shall perform such services with respect thereto as are
described in Exhibit D attached hereto and shall in connection therewith be
subject to the standard of care set forth in such Exhibit D.  Such standard of
care shall not be affected by any other term of this Agreement.

             19.    AMENDMENT, MODIFICATIONS, ETC.  No provision of this
Agreement may be amended, modified or waived except in a writing signed by the
parties hereto.  No waiver of any provision hereto shall be deemed a continuing
waiver unless it is so designated.   No failure or delay on the part of either
party in exercising any power or right under this Agreement operates as a
waiver, nor does any single or partial exercise of any power or right preclude
any other or further exercise thereof or the exercise of any other power or
right.

             20.    TERMINATION.  (a)  TERMINATION OF ENTIRE AGREEMENT.  This
Agreement may be terminated by the Customer or the Custodian by ninety (90)
days' written notice to the other; PROVIDED that notice by the Customer shall
specify the names of the persons to whom the Custodian shall deliver the
Securities in each Account and to whom the Cash in such Account shall be paid.
If notice of termination is given by the Custodian, the Customer shall, within
ninety (90) days following the giving of such notice, deliver to the Custodian a
written notice specifying the names of the persons to whom the Custodian shall
deliver the Securities in each Account and to whom the Cash in such Account
shall be paid.  In either case, the Custodian will deliver such Securities and
Cash to the persons so specified, after deducting therefrom any amounts which
the Custodian determines to be owed to it under Sections 12, 17, and 23.  In
addition, the Custodian may in its discretion withhold from such delivery such
Cash and Securities as may be necessary to settle transactions pending at the
time of such delivery.  The Customer grants to the Custodian a lien and right of
setoff against the Account and all Property held therein from time to time in
the full amount of the foregoing obligations.  If within ninety (90) days
following the giving of a notice of termination by the Custodian, the Custodian
does not receive from the Customer a written notice specifying the names of the
persons to whom the Custodian shall deliver the Securities in each Account and
to whom the Cash in such Account shall be paid, the Custodian, at its election,
may deliver such Securities and pay such Cash to a bank or trust company doing
business in the State of New York to be held and disposed of pursuant to the
provisions of this Agreement, or may continue to hold such Securities and Cash
until a written notice as aforesaid is delivered to the Custodian, provided that
the Custodian's obligations shall be limited to safekeeping.

             (b)    TERMINATION AS TO ONE OR MORE PORTFOLIOS.  This Agreement
may be terminated by the Customer or the Custodian as to one or more Portfolios
(but less than all of the Portfolios) by delivery of an amended Exhibit A
deleting such Portfolios, in which case termination as to such deleted
Portfolios shall take effect ninety (90) days after the date of such delivery,
or such earlier time as mutually agreed.  The execution and delivery of an
amended Exhibit A which deletes one or more Portfolios shall constitute a
termination of this Agreement only with respect to such deleted Portfolio(s),
shall be governed by the preceding provisions of Section 20 as to the
identification of a successor custodian and the delivery of Cash and Securities
of the Portfolio(s) so deleted to such successor custodian, and shall not affect
the obligations of the Custodian and the Customer hereunder with respect to the
other Portfolios set forth in Exhibit A, as amended from time to time.

             21.    NOTICES.  Except as otherwise provided in this Agreement,
all requests, demands or other communications between the parties or notices in
connection herewith (a) shall be in writing, hand delivered or sent by telex,
telegram, cable, facsimile or other means of electronic communication agreed
upon by the parties hereto addressed, if to the Customer, to:

effective when received, or, in the case of a telex, when sent to the proper
number and acknowledged by a proper answerback.

             22.    SEVERAL OBLIGATIONS OF THE PORTFOLIOS.  With respect to any
obligations of the Customer on behalf of each Portfolio and each of its related
Accounts arising out of this Agreement, the Custodian shall look for payment or
satisfaction of any obligation solely to the assets and property of the
Portfolio and such Accounts to which such obligation relates as though the
Customer had separately contracted with the Custodian by separate written
instrument with respect to each Portfolio and its related Accounts.

             23.    SECURITY FOR PAYMENT.  To secure payment of all obligations
due hereunder, the Customer hereby grants to Custodian a continuing security
interest in and right of setoff against each Account and all Property held
therein from time to time in the full amount of such obligations; PROVIDED THAT,
if there is more than one Account and the obligations secured pursuant to this
Section can be allocated to a specific Account or the Portfolio related to such
Account, such security interest and right of setoff will be limited to Property
held for that Account only and its related Portfolio.  Should the Customer fail
to pay promptly any amounts owed hereunder, Custodian shall be entitled to use
available Cash in the Account or applicable Account, as the case may be, and to
dispose of Securities in the Account or such applicable Account as is necessary.
In any such case and without limiting the foregoing, Custodian shall be entitled
to take such other action(s) or exercise such other options, powers and rights
as Custodian now or hereafter has as a secured creditor under the New York
Uniform Commercial Code or any other applicable law.

             24.   REPRESENTATIONS AND WARRANTIES.

      (a)  The Customer hereby represents and warrants to the Custodian that:

assignable by either party, but shall bind the successors in interest of the
Customer and the Custodian.

             26.    PUBLICITY.  Customer shall furnish to Custodian at its
office referred to in Section 21 above, prior to any distribution thereof,

objects in writing within ten (10) business days of receipt thereof (or such
other time as may be mutually agreed) after receipt thereof.  The provisions of
this Section shall survive the termination of this Agreement.

             27.    REPRESENTATIVE CAPACITY AND BINDING OBLIGATION.  A copy of
the Agreement and Declaration of trust of the Customer is on file with the
Secretary of State of the Commonwealth of Massachusetts, and notice is hereby
given that this Agreement is not executed on behalf of the Trustees of the
Customer as individuals, and the obligations of this Agreement are not binding

information provided by each party to the other regarding its business and
operations.  All confidential information provided by a party hereto shall be
used by any other party hereto solely for the purpose of rendering services
pursuant to this Agreement and, except as may be required in carrying out this
Agreement, shall not be disclosed to any third party without the prior consent
of such providing party.  The foregoing shall not be applicable to any
information that is publicly available when provided or thereafter becomes
publicly available other than through a breach of this Agreement, or that is
required or requested to be disclosed by any bank or other regulatory examiner
of the Custodian, Customer, or any Subcustodian, any auditor of the parties
hereto, by judicial or administrative process or otherwise by applicable law or
regulation.

                                      EXHIBIT B


             To Custodian Agreement dated as of October 25, 1995 between
Bankers Trust Company and Allmerica Investment Trust.

                                    PROXY SERVICE

             The following is a description of the Proxy Service referred to in
Section 10 of the above referred to Custodian Agreement.  Terms used herein as
defined terms shall have the meanings ascribed to them therein unless otherwise
defined below.

             The Custodian provides a service, described below, for the
transmission of corporate communications in connection with shareholder meetings
relating to Securities held in Argentina, Australia, Austria, Canada, Denmark,
Finland, France, Germany, Greece, Hong Kong, Indonesia, Ireland, Italy, Japan,
Korea, Malaysia, Mexico, Netherlands, New Zealand, Pakistan, Poland, Singapore,
South Africa, Spain, Sri Lanka, Sweden, United Kingdom, United States, and
Venezuela.  For the United States and Canada, the term "corporate
communications" means the proxy statements or meeting agenda, proxy cards,
annual reports and any other meeting materials received by the Custodian.  For
countries other than the United States and Canada, the term "corporate
communications" means the meeting agenda only and does not include any meeting
circulars, proxy statements or any other corporate communications furnished by
the issuer in connection with such meeting.  Non-meeting related corporate
communications are not included in the transmission service to be provided by
the Custodian except upon request as provided below.

             The Custodian's process for transmitting and translating meeting
agendas will be as follows:

             1)     If the meeting agenda is not provided by the issuer in the
English language, and if the language of such agenda is in the official language
of the country in which the related security is held, the Custodian will as soon
as practicable after receipt of the original meeting agenda by a Subcustodian
provide an English translation prepared by that Subcustodian.

             2)     If an English translation of the meeting agenda is
furnished, the local language agenda will not be furnished unless requested.

             Translations will be free translations and neither the Custodian
nor any Subcustodian will be liable or held responsible for the accuracy thereof
or any direct or indirect consequences arising therefrom, including without
limitation arising out of any action taken or omitted to be taken based thereon.

             If requested, the Custodian will, on a reasonable efforts basis,
endeavor to obtain any additional corporate communication such as annual or
interim reports, proxy statements, meeting circulars, or local language agendas,
and provide them in the form obtained.


             Timing in the voting process is important and, in that regard,
upon receipt by the Custodian of notice from a Subcustodian, the Custodian will
provide a notice to the Customer

<PAGE>

indicating the deadline for receipt of its instructions to enable the voting
process to take place effectively and efficiently.  As voting procedures will
vary from market to market, attention to any required procedures will be very
important.  Upon timely receipt of voting instructions, the Custodian will
promptly forward such instructions to the applicable Subcustodian.  If voting
instructions are not timely received, the Custodian shall have no liability or
obligation to take any action.

             For Securities held in markets other than those set forth in the
first paragraph, the Custodian will not furnish the material described above or
seek voting instructions.  However, if requested to exercise voting rights at a
specific meeting, the Custodian will endeavor to do so on a reasonable efforts
basis without any assurance that such rights will be so exercised at such
meeting.

             If the Custodian or any Subcustodian incurs extraordinary expenses
in exercising voting rights related to any Securities pursuant to appropriate
instructions or direction (e.g., by way of illustration only and not by way of
limitation, physical presence is required at a meeting and/or travel expenses
are incurred), such expenses will be reimbursed out of the Account containing
such Securities unless other arrangements have been made for such reimbursement.

             It is the intent of the Custodian to expand the Proxy Service to
include jurisdictions which are not currently included as set forth in the
second paragraph hereof.  The Custodian will notify the Customer as to the
inclusion of additional countries or deletion of existing countries after their
inclusion or deletion and this Exhibit B will be deemed to be automatically
amended to include or delete such countries as the case may be.

                                  EXHIBIT 16

                                  PERFORMANCE

The Trust may advertise performance information for the Funds and may compare 
performance of the Funds to other investment or relevant indices.  The Funds 
may also advertise "yield", "total return" and other non-standardized total 
return data.  For the non-money market funds, "yield" is calculated 
differently than for the Money Market Fund.  The Money Market Fund may 
advertise "yield" or "effective yield".  ALL PERFORMANCE FIGURES ARE BASED ON 
HISTORICAL EARNINGS AND ARE NOT INTENDED TO INDICATE FUTURE PERFORMANCE.  The 
Funds' share price, yield and total return fluctuate in response to market 
conditions and other factors, and the value of Fund shares when redeemed may 
be more or less than their original cost.

YIELDS AND TOTAL RETURNS QUOTED FOR THE FUNDS INCLUDE THE EFFECT OF DEDUCTING 
THE FUNDS' EXPENSES, BUT MAY NOT INCLUDE CHARGES AND EXPENSES ATTRIBUTABLE TO 
A PARTICULAR INSURANCE PRODUCT.  SINCE SHARES OF THE FUNDS CAN BE PURCHASED 
ONLY THROUGH A VARIABLE ANNUITY OR VARIABLE LIFE CONTRACT, YOU SHOULD 
CAREFULLY REVIEW THE PROSPECTUS OF THE INSURANCE PRODUCT YOU HAVE CHOSEN FOR 
INFORMATION ON RELEVANT CHARGES AND EXPENSES.  INCLUDING THESE CHARGES IN THE 
QUOTATIONS OF THE FUNDS' YIELD AND TOTAL RETURN WOULD HAVE THE EFFECT OF 
DECREASING PERFORMANCE.  PERFORMANCE INFORMATION FOR THE INSURANCE PRODUCT 
MUST ALWAYS ACCOMPANY, AND BE REVIEWED WITH, ANY PERFORMANCE INFORMATION 
QUOTED FOR THE FUNDS.


YIELD OF THE FUNDS OTHER THAN THE MONEY MARKET FUND

The 30-day (or one month) standard yield of the Funds other than the Money 
Market Fund is calculated as follows:

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

     Where:  a = dividends and interest earned by a Fund during the period;

             b = expenses accrued for the period (net of reimbursements);

             c = average daily number of shares outstanding during the 
                 period, entitled to receive dividends; and

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

For the purpose of determining net investment income earned during the period 
(variable "a" in the formula), dividend income on equity securities held by a 
Fund is recognized by accruing


<PAGE>

1/360 of the stated dividend rate of the security each day that the security 
is in the Fund.  Except as noted below, interest earned on debt obligations 
held by a Fund is calculated by computing the yield to maturity of each 
obligation based on the market value of the obligation (including actual 
accrued interest) at the close of business on the last business day of each 
month, or, with respect to obligations purchased during the month, the 
purchase price (plus actual accrued interest) and dividing the result by 360 
and multiplying the quotient by the market value of the obligation (including 
actual accrued interest) in order to determine the interest income on the 
obligation for each day of the subsequent month that the obligation is held 
by the Fund.  For purposes of this calculation, it is assumed that each month 
contains 30 days.  The maturity of an obligation with a call provision is the 
next call date on which the obligation reasonably may be expected to be 
called or, if none, the maturity date.  With respect to debt obligations 
purchased at a discount or premium, the formula generally calls for 
amortization of the discount or premium.  The amortization schedule will be 
adjusted monthly to reflect changes in the market value of such debt 
obligations.  Expenses accrued for the period (variable "b" in the formula) 
include all recurring fees charged by a Fund to all shareholder accounts in 
proportion to the length of the base period and the Fund's mean (or median) 
account size.  Undeclared earned income will be subtracted from the offering 
price per share (variable "d" in the formula).


MONEY MARKET FUND - YIELD AND EFFECTIVE YIELD

The yield of the Money Market Fund refers to the net income generated by an 
investment in the Fund over a stated seven-day period, expressed as an annual 
percentage rate.  Yield is computed by determining the net change (exclusive 
of capital changes) in the value of a hypothetical pre-existing account 
having a balance of 1 (one) share at the beginning of a seven-day calendar 
period, dividing the next change in account value by the value of the account 
at the beginning of the period, and multiplying the return over the seven-day 
period by 365/7.  Thus the income is "annualized":  the amount of income 
generated by the investment during the seven-day period is assumed to be 
generated each week over a 52-week period and is shown as a percentage of the 
investment.  For purposes of the calculation, net change in account value 
reflects the value of additional shares purchased with dividends from the 
original share and dividends declared on both the original share and any 
additional shares, but does not reflect realized gains or losses or 
unrealized appreciation or depreciation.

The effective yield is calculated similarly, but the income earned by an 
investment in the Money Market Fund is assumed to be reinvested.  The 
"effective yield" will be slightly higher than the "yield" because of this 
compounding effect.


TOTAL RETURN

The Funds may advertise total return.  The total return shows what an 
investment in each Fund would have earned over a specific period of time 
(one, five or ten years or since commencement of operations, if less) 
assuming that all distributions and dividends by the Fund were reinvested, 
and less all recurring fees.

From time to time, the Fund may state its total return in advertisements and 
investor communications.  Total return may be stated for any relevant period 
as specified in the advertisement or communication.


<PAGE>

Any statement of total return or other performance data on the Fund will be 
accompanied by information on the Fund's average annual total return over the 
most recent four calendar quarters and the period from the Fund's inception 
of operations.  The Fund may also advertise aggregate annual total return 
information over different periods of time.

A Fund's average annual total return is determined by reference to a 
hypothetical $1,000 investment that includes capital appreciation and 
depreciation for the stated period, according to the following formula:

                           P(1 + T)(n) = ERV

     Where:     P   = A hypothetical initial purchase of $1,000

                T   = average annual total return

                n   = number of years

                ERV = Ending Redeemable Value of the hypothetical purchase 
                      at the end of the period

Total return quoted in advertising reflects all aspects of the Fund's return, 
including the effect of reinvesting dividends and capital gains 
distributions, and any change in the Fund's net asset value per share over 
the period.

AVERAGE ANNUAL RETURNS are calculated by determining the change in value of a 
hypothetical investment in the Fund over a stated period, and calculating 
the annually compounded percentage rate that would have produced the same 
result if the rate of growth or decline in value has been constant over the 
period.  Average annual returns covering periods of less than one year are 
calculated by determining the Fund's total return for the period, 
extrapolating that return for a full year, and stating the result as an 
annual return.  Because this method assumes that performance will remain 
constant for the entire year, when in fact it is unlikely that performance 
will remain constant, average annual returns for a partial year must be 
viewed as strictly theoretical information.

INVESTORS SHOULD ALSO BE AWARE THAT A FUND'S PERFORMANCE IS NOT CONSTANT OVER 
TIME, BUT VARIES FROM YEAR TO YEAR.  AVERAGE ANNUAL RETURN REPRESENT AVERAGED 
FIGURES AS OPPOSED TO THE ACTUAL PERFORMANCE OF THE FUND.

A Fund may also quote cumulative total returns which reflect the simple 
change in value of an investment over a stated period.  Average annual total 
returns and cumulative total returns may be quoted as a percentage or as a 
dollar amount.  They may be calculated for a single investment, for a series 
of investments, or for a series of redemptions over any time period.  Total 
returns may be broken down into their components of income and capital in 
order to show their respective contributions to total return.  Performance 
information may be quoted numerically or in a table, graph or similar 
illustration.
