    This Prospectus describes individual variable annuity contracts (each a
"CONTRACT" and collectively the "CONTRACTS") offered by Western-Southern Life
Assurance Company (the "COMPANY"), a life insurance company which is a wholly
owned subsidiary of The Western and Southern Life Insurance Company ("WESTERN &
SOUTHERN"). The Contracts are designed for individual investors and group plans
that desire to accumulate capital on a tax-deferred basis for retirement or
other long term objectives. The owner of a Contract may select any one of three
death benefit options. Contracts may be purchased on either a non-qualified
basis or on a qualified basis in connection with qualified retirement and
pension plans. Generally, non-qualified Contracts may be purchased by making a
payment of at least $10,000, and qualified Contracts may be purchased by making
a payment of at least $1,000. Subsequent payments to a Contract must be at least
$100. Payments will be invested as the Contract Owner directs in one or more
sub-accounts (each a "SUB-ACCOUNT" and together called the "VARIABLE ACCOUNT"
(see further definitions in the Glossary)) of Western-Southern Life Assurance
Company Separate Account 1 ("SEPARATE ACCOUNT 1"). Each Sub-Account invests in a
corresponding portfolio of Select Advisors Variable Insurance Trust or of Select
Advisors Portfolios, each of which is an open-end diversified management
investment company, or in a fixed-rate option (the "FIXED ACCOUNT" (see further
definition in the Glossary)) funded through the Company's general account.
 
    The Sub-Accounts in which Contract Owners may invest are: Emerging Growth,
International Equity, Growth & Income, Balanced, Income Opportunity, Bond and
Standby Income. Information regarding these investment options is set forth
under the caption THE VARIABLE ACCOUNT herein. Five of the seven Sub-Accounts,
Emerging Growth, International Equity, Balanced, Income Opportunity and Standby
Income, invest in corresponding Portfolios of Select Advisors Variable Insurance
Trust, a Massachusetts business trust (the "VI TRUST"). THIS PROSPECTUS IS VALID
ONLY WHEN ACCOMPANIED BY THE CURRENT PROSPECTUS FOR THE VI TRUST (THE "VI TRUST
PROSPECTUS"), a copy of which is bound with this Prospectus. The remaining two
Sub-Accounts, Growth & Income and Bond, invest in the Growth & Income Portfolio
II and Bond Portfolio II of Select Advisors Portfolios (the "SA TRUST" (see
further definition in the Glossary)) under a Hub and Spoke(R) arrangement.
Unlike the Portfolios of the VI Trust, which receive investments only from
Separate Account 1 and other separate accounts of the Company, the SA Trust may
also receive investments for its Growth & Income Portfolio II and Bond Portfolio
II from other insurance company separate accounts registered as investment
companies under the Investment Company Act of 1940. See "Special Information
Concerning Hub and Spoke(R) Structure" in this Prospectus. Hub and Spoke(R) is a
registered service mark of Signature Financial Group, Inc.
 
    THE CONTRACTS ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR ENDORSED
BY, ANY BANK, AND THE CONTRACTS ARE NOT FEDERALLY INSURED BY THE FEDERAL DEPOSIT
INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD, THE NATIONAL CREDIT UNION
SHARE INSURANCE FUND OR ANY OTHER AGENCY. MUTUAL FUNDS AND VARIABLE ANNUITIES
INVOLVE INVESTMENT RISK, INCLUDING POSSIBLE LOSS OF PRINCIPAL.
 
    The Income Opportunity Portfolio of the VI Trust may invest up to 100% of
its total assets in non-investment grade bonds (commonly known as "junk bonds")
issued by both U.S. and foreign issuers, which entail greater risk of untimely
interest and principal payments, default and price volatility than higher rated
securities, and may present problems of liquidity and valuation. See "Income
Opportunity Portfolio" in the VI Trust Prospectus.
 
    This Prospectus tells investors briefly the information they should know
before investing in the Contracts. Investors should read and retain this
Prospectus for future reference. Additional information about the Contract and
the Variable Account has been filed with the Securities and Exchange Commission
in a Statement of Additional Information dated October 20, 1997. The Statement

             PART I -- DISCUSSION OF THE VARIABLE ANNUITY CONTRACT
 
                             FEE AND EXPENSE TABLES
 
     The following tables provide information concerning Contract Owner
transaction expenses and annual operating expenses of the Variable Account and
each Sub-Account. For these purposes, expenses of the Portfolio in which each
Sub-Account invests are treated as if they were expenses of that Sub-Account,
since that is their practical effect. It is expected that the combined expenses
per Accumulation Unit of each Sub-Account and its corresponding Portfolio will,
at a minimum, be approximately equal to and may be less than the expenses that
would be incurred by each Sub-Account alone if, instead of investing in such
Portfolio, the Sub-Account retained an investment advisor and portfolio advisors
and invested directly in the types of securities held by the Portfolio. For
additional information regarding these expenses, see "Charges."

 *Also referred to as a "Surrender Charge." See "Surrender Charge."
 
**In certain states in which it has received the necessary regulatory approvals,
  the Company may waive, reduce or eliminate the annual Contract Maintenance
  Charge. This charge is not assessed against Contracts having a Contract Value
  of more than $50,000. After the tenth Contract Anniversary the charge for any
  Contract having a Contract Value of less than $50,000 is the lesser of (a) $40

PORTFOLIO EXPENSES
 
     The expenses of each of the VIT Portfolios and each of the SAT Portfolios
shown below are assessed at the underlying Portfolio level and are not direct
charges against the assets of the Sub-Accounts or reductions from Contract
Value, although such charges are borne indirectly by Contract Owners. Portfolio
expenses are taken into consideration in computing the net asset value of each
Portfolio, which is the price used to calculate the Variable Account Value.
However, under agreements (the "SPONSOR AGREEMENTS") with the VI Trust and the
 
                                        3

SA Trust, Touchstone Advisors, Inc., as sponsor of the two trusts (the
"SPONSOR"), has agreed to reimburse each Portfolio for those annual operating
expenses of the Portfolio exceeding a specified percentage (the "EXPENSE CAP")
of the Portfolio's average daily net assets. For additional information
regarding the Sponsor Agreements, see "Sponsor." Operating expenses for this
purpose include fees of the Advisor, fees of the Administrator, amortization of
organizational expenses, legal and accounting fees and Sponsor fees, but do not
include interest, taxes, brokerage commissions and other portfolio transaction
expenses, capital expenditures and extraordinary expenses. Fees and expenses in
the table are expressed as a percentage of average daily net assets.

    quarter after December 31, 1998, by giving at least 30 days prior written
    notice, and will be terminated if the Sponsor ceases to be the investment
    advisor for the Portfolio. If a Sponsor Agreement is terminated, actual
    Portfolio expenses may exceed those shown in the table. For more information
    regarding each Portfolio's expenses, see "Expenses of the VIT Portfolios and
    SAT Portfolios; Expense Caps" herein, the VI Trust Prospectus, and the
    Statement of Additional Information (available on request from the Special
    Markets Service Center).
 
    * The advisory fee for the Balanced Portfolio was 0.70% prior to May 1, 
      1997, and the advisory fee for the Growth & Income Portfolio was 0.75% 
      prior to September 18, 1997. The information under "Advisor Fee" and 
      "Other Expenses" in the table for these two Portfolios has been restated 
      to reflect the current advisory fees.
 
EXAMPLE
 
     The following charts depict the expenses that would be incurred under the
Contract assuming a $1,000 investment in each Sub-Account and a 5% annual return
on that investment. Portfolio expenses have been estimated at the Expense Cap
for each Portfolio. THE DOLLAR FIGURES IN EACH CHART ARE ILLUSTRATIVE ONLY AND
SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL
EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN. The effect of the Contract
Maintenance Charge is calculated by expressing it as a percentage of the average
Contract Value, which is assumed, for this purpose only, to be $25,000. Premium
taxes currently are imposed by certain states and municipalities on Purchase
Payments made under the Contracts. Premium taxes are not reflected in the
examples below; where applicable, such taxes may decrease the amount of each
Purchase Payment available for allocation.

                            SUMMARY OF THE CONTRACT
GENERAL
 
     The purpose of the Contract is to permit an Owner to accumulate funds on a
tax-deferred basis by investing in one or more alternatives, and to permit the
Owner or the Owner's designee to receive annuity income payments starting on the
Income Date. An Owner may invest in one or more of seven Sub-Accounts of the
Variable Account and in the Company's Fixed Account. Each Sub-Account will, in
turn, invest solely in one of seven Portfolios, five of which are Portfolios of
the VI Trust and two of which are Portfolios of the SA Trust. Each Trust is an
open-end diversified management investment company. The VI Trust is organized as
a Massachusetts business trust and the SA Trust is organized as a New York
trust. For further information regarding these two trusts, see "The VI Trust and
the SA Trust." An investment in the Fixed Account will be held and managed by
the Company through its general account. See "The Fixed Account."
 
     Assets allocated by Contract Owners to the Variable Account are held by
Separate Account 1. Such assets are segregated from other assets of the Company
but not from assets attributable to other variable annuity contracts issued
through Separate Account 1. Owners bear the investment risk with respect to the
Sub-Accounts which they select, and there is no guarantee that amounts invested
by the Owner in the Sub-Accounts will increase or retain their value. See "The
Variable Account." The Company guarantees that amounts allocated by an Owner to
the Fixed Account will earn interest at a rate determined periodically by the
Company and in effect at the time of each investment. See "The Fixed Account."
 
MINIMUM AND MAXIMUM INVESTMENTS
 
     A Contract may be purchased on a Non-Qualified basis or on a Qualified
basis as part of a plan which qualifies under Sections 401, 403(b), 408 or 457
of the Code. The initial Purchase Payment must be at least $10,000 for
Non-Qualified Contracts and $1,000 for Qualified Contracts (or $50 for Qualified
Contracts if payments will be made under an automatic or scheduled installments
plan). Each subsequent payment must be at least $100 for either Contract.
However, monthly Purchase Payments of not less than $50 will be permitted for
either Contract under an automatic or scheduled installment plan. If no purchase
payments have been received for two full years and both (a) the total Purchase
Payments less any partial withdrawals and (b) the Contract Value, are less than
$2,000, the Company will, after 14 days prior written notice to the Owner,
terminate the Contract and pay the Surrender Value to the Owner. The cumulative
total of all Purchase Payments under a Contract may not exceed $500,000 without
the prior consent of the Company. See "Purchase Of A Contract-Minimum/Maximum
Investments."
 
VARIABLE ANNUITY SERVICE CENTER
 
     Investments in or withdrawals from a Contract, transfers of amounts to or
from the Variable Account and other directions with respect to the investment of
Purchase Payments should be directed to the Company at the Touchstone Special
Markets Service Center, P.O. Box 2850, Cincinnati, Ohio 45201-2850 (the "Special
Markets Service Center").
 
TEN-DAY FREE LOOK
 
     To be sure that the Owner is satisfied with the Contract, the Owner has a
ten-day "free look." Within ten days of the date the Contract is received by the
Owner, it may be returned to the Company at the Special Markets Service Center.
If the Contract is received by the Company within such time, the Company will
void the Contract, and the Contract Value, plus any amount deducted from the
initial Purchase Payment prior to allocation to the Sub-Accounts or the Fixed
Account, will then be refunded in full unless otherwise required by state or
federal law. See "Free Look Privilege."
 
INVESTMENT OPTIONS
 
     Purchase Payments will be invested by the Company, in the proportions that
the Owner directs, in the Fixed Account and the Sub-Accounts. See "Allocation of
Purchase Payments." The Variable Account currently has seven Sub-Accounts, each
of which invests exclusively in one of the VIT Portfolios or one of the SAT
 
                                        6

Portfolios. The VIT Portfolios are Emerging Growth, International Equity,
Balanced, Income Opportunity and Standby Income. The SAT Portfolios are Growth &
Income and Bond. Information regarding the investment options presented by the
VIT Portfolios and the SAT Portfolios is set forth under the caption "The VI
Trust and the SA Trust" herein. More detailed information regarding the SAT
Portfolios will be found under the caption "Investment Objectives, Policies and
Restrictions" in this Prospectus. Detailed information regarding the VIT
Portfolios will be found in the VI Trust Prospectus. Owners may transfer funds
among Sub-Accounts once every thirty days. Transfers from the Variable Account
to the Fixed Account may be made once during any Contract Year. Transfers from
the Fixed Account to the Variable Account also may be made once during any
Contract Year; such transfers are permitted up to a maximum of 25% of the Fixed
Account Value. See "Transfers."
 
PURCHASE PAYMENTS
 
     The Owner may elect to allocate Purchase Payments to the Sub-Accounts or
the Fixed Account or any combination of these alternatives. Purchase Payments
will be processed by the Company on the day received at the Special Markets
Service Center, if received in good order no later than 4:00 p.m. Eastern Time
on any Valuation Date. Payments received in good order later in the day, or on
any day not a Valuation Date, will be processed on the next Valuation Date.
Purchases by the Sub-Accounts of shares of the corresponding VIT Portfolios or
of interests in the corresponding SAT Portfolio will be made on the next
Valuation Date following processing, at the value of the corresponding Portfolio
on the date of processing. As the value of the investments in the Sub-Accounts
increases or decreases, the Variable Account Value increases or decreases. See
"Allocation of Purchase Payments."
 
WITHDRAWAL; SURRENDER
 
     Prior to the Income Date, the Owner may withdraw all or part of the
Contract Value. A withdrawal of all of the Contract Value is a "SURRENDER."
During the first seven years following the receipt of a Purchase Payment, such
withdrawals (to the extent they exceed any available "free" amounts, as
described under the caption "Surrender Charge -- 'Free' Amounts") generally will
be subject to a Surrender Charge. This charge is 8% of the amount of any
Purchase Payment withdrawn less than one year following receipt of such payment
and decreases over time, reducing to zero after the seventh year from the
receipt of a Purchase Payment. The minimum partial withdrawal is $250, and the
Contract Value following any partial withdrawal must be at least $2,000. Where
permitted by applicable law, the Company will waive the Surrender Charge if the
Owner or the Annuitant is confined to a long term care facility or hospital (as
defined in the Contract) for at least 30 days prior to surrender, and reserves
the right to waive the Surrender Charge in certain other circumstances. See
"Surrenders and Partial Withdrawals" and "Surrender Charge." Certain withdrawals
may be subject to an additional tax on premature distributions as well as to
federal income tax. See "Federal Income Taxation."
 
INCOME PAYMENT OPTIONS
 
     The Contract offers five fixed income payment options, unless otherwise
limited by applicable state insurance laws. Income may be paid in installments,
either for a fixed period of one to 30 years or in a fixed amount. Income also
may be paid under a life income alternative, either with or without a guaranteed
payment period. In addition, life income may be paid over the lifetimes of the
Annuitant and another designated person. Other income payment options may be
selected with prior approval of the Company. If no income option is selected by
the Owner, the Contract provides for a monthly annuity payment, beginning on the
Income Date if the Annuitant is then living, payable for life with ten years
certain. See "Selection of Income Payment Option." If the Annuitant dies after
the Income Date, the amount and manner of any continuing payments will depend
upon the income option selected. See "Income Payment Options."
 
DEATH BENEFIT
 
     If the Owner dies before the Income Date, the Company will pay a Death
Benefit to the Beneficiary selected by the Owner. See "Death Benefit." The Death
Benefit paid will be the greatest of three alternative values calculated as of
the Valuation Date by which satisfactory proof of death, death benefit payment
instructions and election of settlement option have been received in good order
by the Company (the "BENEFIT
 
                                        7
<PAGE>   14
 
DETERMINATION DATE"). One such value, the Contract Value, applies in all cases,
regardless of the age of the Owner or any option selected by the Owner. A second
value, the return of Purchase Payments (less prior withdrawals), also applies in
all cases. The third value will be determined pursuant to one of three available
Death Benefit Options, which must be selected by the Owner when the Contract is
first issued. See "Death Benefit -- Death Benefit Options."
 
CHARGES
 
     Surrender Charge.  The Company does not deduct a sales charge from Purchase
Payments made for Contracts. However, if any part of the Contract Value is
withdrawn, the Company will, with certain exceptions, deduct from the Owner's
Contract Value a Surrender Charge not to exceed 8% of the lesser of (i) the
total of all purchase payments made within 84 months prior to the date of the
request to surrender, and (ii) the amount surrendered. This charge, when
applicable, is imposed to permit the Company to recover sales expenses that have
been incurred by the Company. See "Surrenders and Partial Withdrawals" and
"Surrender Charge."
 
     Contract Maintenance and Contract Administration Charges.  In addition, on
each Contract Anniversary (and upon surrender) the Company will deduct an annual
maintenance charge (the "CONTRACT MAINTENANCE CHARGE") of not more than $40 from
the Contract Value. In certain states, the Company may waive, reduce or
eliminate such charge. No Contract Maintenance Charge will be incurred if the
Contract Value is $50,000 or more on the date when the Contract Maintenance
Charge is deducted. The Company also will deduct on a daily basis an
administration charge (the "CONTRACT ADMINISTRATION CHARGE") equal to an annual
rate of 0.15% of the Variable Account Value. These charges are to reimburse the
Company for administrative expenses related to the issue and maintenance of the
Contract. The Company does not expect to recover from these charges an amount in
excess of accumulated administrative expenses. See "Administrative Charges."
 
     Mortality and Expense Risk Charge.  The Company deducts on a daily basis a
charge to compensate for the mortality risk assumed by the Company (the
"MORTALITY RISK CHARGE"). The charge ranges from 0.85% to 1.05%, depending upon
the Death Benefit Option selected by the Owner. The charge is 0.85% if the Owner
selects the Standard Death Benefit Option, 0.95% for the Annual Step-Up Death
Benefit Option and 1.05% for the Six Percent Accumulating Death Benefit Option.
In addition, the Company deducts on a daily basis a charge equal to an annual
rate of 0.35% of the Variable Account Value as compensation for the Company's
risk in agreeing not to increase administrative charges on the Contracts
regardless of actual administrative costs (the "EXPENSE RISK CHARGE"). The
Mortality Risk Charge and Expense Risk Charge are together referred to as the
"MORTALITY AND EXPENSE RISK CHARGE." For additional information, see "Mortality
and Expense Risk Charge" and "Death Benefit."
 
     Other.  Premium taxes payable to any governmental entity will be charged
against the Contracts. See "Premium Taxes" and "Other Taxes."
 
     The Company may include as a component of the Net Investment Factor (see
"Accumulation Unit Value") a charge or credit for any taxes reserved, which are
determined by the Company to have resulted from the investment operations of any
Sub-Account. See "Allocation of Purchase Payments" and "Other Taxes."
 
     The Portfolios of the VI Trust and of the SA Trust accrue management fees
and other expenses daily and pay them monthly. See "Expenses of VIT Portfolios
and SAT Portfolios; Expense Caps."
 
     THE FOREGOING SUMMARY IS INTENDED TO PROVIDE ONLY AN OVERVIEW OF THE MORE
SIGNIFICANT ASPECTS OF THE CONTRACT. DETAILED INFORMATION IS PROVIDED IN
SUBSEQUENT SECTIONS OF THIS PROSPECTUS AND IN THE CONTRACT. THE CONTRACT
(INCLUDING ANY AMENDMENTS, RIDERS AND ENDORSEMENTS) TOGETHER WITH THE
APPLICATION FORM CONSTITUTES THE ENTIRE AGREEMENT BETWEEN THE OWNER AND THE

                            PERFORMANCE INFORMATION
GENERAL
 
     The Variable Account may advertise certain performance information
regarding the Sub-Accounts from time to time. Such performance information will
be based upon historical performance and is not intended to predict future
performance under an actual Contract.
 
     Average annual total return quotations represent the average compounded
rate of return on a hypothetical initial investment of $1,000. Average annual
total return reflects all historical investment results, less all charges and
deductions applied against a Sub-Account (including any Surrender Charge that
might apply if an Owner terminated the Contract at the end of the indicated
period, but excluding any deductions for premium taxes). The rate for each
Sub-Account is computed by comparing a hypothetical initial investment of $1,000
in the Sub-Account to the hypothetical Surrender Value of that investment at the
end of specifically defined 1, 5 and 10 year periods or for the life of the
Contract.
 
     It is important to note that total return figures are based on historical
earnings and are not intended to indicate future performance. The Statement of
Additional Information describes in more detail the methods used to determine
total return.
 
RATINGS; INDEXES
 
     In reports or other communications to shareholders or in advertising
material, a Sub-Account may also quote non-standardized total return figures,
such as non-annualized figures (provided that these figures are accompanied by
standardized total return figures calculated as described above), as well as
compare its performance with that of other separate accounts as listed in the
rankings prepared by Lipper Analytical Services, Inc. or similar independent
services that monitor the performance of separate accounts. The performance
information also may include evaluations of the separate accounts published by
nationally recognized ranking services and by financial publications that are
nationally recognized.
 
     Additional information regarding the calculation of performance information
appears in the Statement of Additional Information.
 
               FACTS ABOUT THE COMPANY, THE VARIABLE ACCOUNT AND
                               THE FIXED ACCOUNT
 
THE COMPANY
 
     The Company is a stock life insurance company organized under the laws of
the State of Ohio on December 1, 1980. The Company is a wholly-owned subsidiary
of The Western and Southern Life Insurance Company, a mutual life insurance
company originally organized under the laws of the State of Ohio on February 23,
1888 ("WESTERN & SOUTHERN"). Both companies are in the business of issuing
insurance and annuity contracts. The executive offices of both companies are
located at 400 Broadway, Cincinnati, Ohio 45202 and their telephone number is
(513) 629-1800.
 
THE VARIABLE ACCOUNT
 
     The Variable Account is held by the Company's Separate Account 1, a
separate investment account of the Company established pursuant to Ohio law on
July 27, 1992. Separate Account 1 is used to support the Contracts described in
this Prospectus and other variable annuity contracts of the Company and for
other purposes permitted by law. Separate Account 1 is registered with the
Securities and Exchange Commission (the "SEC") as a unit investment trust under
the Investment Company Act of 1940 (the "1940 ACT"). Separate Account 1 consists
of Variable Account assets held for the benefit of Contract Owners and assets
held, through similar accounts, for the benefit of owners of other variable
annuity contracts issued by Separate Account 1.
 
     The Company owns the assets of Separate Account 1. As required by law,
however, the assets of Separate Account 1 are kept separate from the Company's
general account assets and any other separate account assets and are held
exclusively for the benefit of Owners and Beneficiaries of the Contracts and of
other variable
 
                                        9
<PAGE>   16
 
annuity contracts issued by Separate Account 1. These assets may not be charged
with liabilities from any other business which the Company may conduct. The
Company is obligated to pay all benefits provided under the Contracts and all
benefits provided under other variable annuity contracts issued by Separate
Account 1.
 
     Each Sub-Account of the Variable Account is administered and accounted for
as part of the general business of the Company; however, the income, capital
gains or capital losses of each Sub-Account are credited to or charged against
the assets held in that Sub-Account in accordance with the terms of each
Contract without regard to the income, capital gains or capital losses of any
other Sub-Account or arising out of any other business of the Company.
 
     Each Sub-Account invests either in a Portfolio of the VI Trust or in a
Portfolio of the SA Trust. The VI Trust is a Massachusetts business trust and
the SA Trust is a New York trust. Each Trust is registered as an open-end
management investment company under the 1940 Act. The Portfolios are described
generally below. Owners periodically may transfer funds between Sub-Accounts or
change allocations among Sub-Accounts. See "Transfers."
 
     THE VI TRUST AND THE SA TRUST
 
     The Variable Account consists of seven Sub-Accounts, each of which invests
exclusively in one of the VIT Portfolios or in one of the SAT Portfolios. The
investment objective of each Sub-Account is the same as the corresponding
Portfolio, each of which is described briefly below. There is no assurance that
any Contract or Portfolio will meet its investment objective.
 
                                 VIT PORTFOLIOS
 
          EMERGING GROWTH PORTFOLIO has a primary investment objective of
     capital appreciation with income as a secondary investment objective. The
     Portfolio attempts to achieve its investment objective through investment
     primarily in the common stock of smaller, rapidly growing companies.
 
          INTERNATIONAL EQUITY PORTFOLIO has an investment objective of long
     term capital appreciation through investment primarily in equity securities
     of companies based outside the United States.
 
          BALANCED PORTFOLIO has an investment objective of growth of capital
     and income through investment in common stocks and fixed-income securities.
 
          INCOME OPPORTUNITY PORTFOLIO has an investment objective of high
     current income through investment in high yield, non-investment grade debt
     securities (commonly known as "junk bonds") of both U.S. and non U.S.
     issuers and in mortgage-related securities. To the extent consistent with
     its primary objective, the Portfolio will also seek capital appreciation.
 
          STANDBY INCOME PORTFOLIO has an investment objective of high current
     income to the extent consistent with relative stability of principal, which
     it attempts to achieve through investment in short-term, investment grade
     debt securities.
 
                                 SAT PORTFOLIOS
 
          GROWTH & INCOME PORTFOLIO has an investment objective of long term
     capital appreciation and dividend income through investment primarily in
     common stocks of high quality companies.
 
          BOND PORTFOLIO has an investment objective of providing a high level
     of current income primarily through investment in investment grade bonds.
 
     Several of the Portfolios invest in non-investment grade (or "junk") bonds,
which entail greater risk of untimely interest and principal payments, default
and price volatility than higher rated securities and may present problems of
liquidity and valuation. The Income Opportunity Portfolio and the International
Equity Portfolio of the VI Trust, which are described in more detail in the VI
Trust Prospectus, may invest up to 100% and 35%, respectively, of their total
assets in non-investment grade bonds. See "Income Opportunity Portfolio,"
"International Equity Portfolio" and "Medium and Lower Rated ("Junk Bonds") and
Unrated Securities" in the
 
                                       10
<PAGE>   17
 
VI Trust Prospectus. The Growth & Income Portfolio and Bond Portfolio of the SA
Trust, which are described more fully in Part II of this Prospectus, may invest
up to 5% and 35%, respectively, of their total assets in non-investment grade
bonds. See "Growth & Income Portfolio," "Bond Portfolio" and "Medium and Lower
Rated ("Junk Bonds") and Unrated Securities." Such investments may not be
appropriate for all investors.
 
     MORE COMPLETE INFORMATION ABOUT THE FIVE PORTFOLIOS OF THE VI TRUST,
INCLUDING THE ASSOCIATED RISKS, IS SET FORTH IN THE VI TRUST PROSPECTUS. SIMILAR
INFORMATION WITH RESPECT TO THE GROWTH & INCOME AND THE BOND PORTFOLIOS OF THE
SA TRUST IS CONTAINED IN PART II OF THIS PROSPECTUS. PROSPECTIVE PURCHASERS OF
CONTRACTS SHOULD READ THE VI TRUST PROSPECTUS AND PART II OF THIS PROSPECTUS IN
CONJUNCTION WITH THE INFORMATION REGARDING THE VARIABLE ACCOUNT CONTAINED
HEREIN.
 
     ADVISORS AND SERVICE PROVIDERS
 
     Both the VI Trust and the SA Trust have entered into investment advisory
agreements with Touchstone Advisors, Inc. (the "ADVISOR"). The Advisor, in turn,
has entered into investment advisory agreements with separate investment
advisors selected for each Portfolio (the "PORTFOLIO ADVISORS"). It is the
responsibility of the Advisor to select the Portfolio Advisors, subject to the
review and approval of the trustees of the VI Trust or the SA Trust, as the case
may be, and to review the ongoing investment strategy of each Portfolio Advisor
and the performance of the Portfolios. Each Trust has entered into agreements
with Investors Bank and Trust Company ("INVESTORS BANK" or the "ADMINISTRATOR")
pursuant to which Investors Bank provides administrative and fund accounting
services for each Trust. The Advisor employs, at its expense, the services of
RogersCasey Sponsor Services, Inc. ("ROGERSCASEY"), a research firm specializing
in appraisal and comparison of investment managers, as a consultant to assist in
evaluating portfolio advisors. See "Consultant to the Advisor."
 
     ADDITIONS, DELETIONS AND SUBSTITUTIONS OF INVESTMENTS
 
     The Company may from time to time make additional Sub-Accounts available.
These Sub-Accounts will invest in investment portfolios that the Company deems
suitable for the Contracts. The Company also has the right, upon approval of
affected Contract Owners or approval of the SEC, to substitute a new investment
portfolio or similar investment option for the Portfolio in which a Sub-Account
invests. A substitution may become necessary if, in the Company's judgment, the
Portfolio or other investment option no longer suits the purposes of the
Contracts. This may happen due to unsatisfactory investment performance, a
change in laws or regulations, a change in a Portfolio's investment objectives
or restrictions, because the Portfolio is no longer available for investment, or
for some other reason. The Company would obtain prior approval from the SEC to
the extent required and any other required approvals before making such a
substitution. The Company also reserves the right to eliminate Sub-Accounts from
the Variable Account or to combine two or more Sub-Accounts, and the right to
operate the Variable Account as a management investment company under the 1940
Act or any other form permitted by law or to deregister the Variable Account
under the 1940 Act in the event such registration no longer is required.
 
THE FIXED ACCOUNT
 
     Due to exemptive and exclusionary provisions, interests in the Fixed
Account have not been registered under the Securities Act of 1933 (the "1933
ACT") and the Company's general account has not been registered as an investment
company under the 1940 Act. Accordingly, interests in the Fixed Account are not
subject to the provisions of those acts, and the Company has been advised that
the staff of the SEC has not reviewed the disclosures in this Prospectus
relating to the Fixed Account.
 
     As noted earlier, a Contract Owner may allocate purchase payments or
transfer all or part of the Owner's Contract Value to the Fixed Account. Funds
allocated or transferred to the Fixed Account will not fluctuate with the
investment experience of the Company's general account. The Company guarantees
that the portion of an Owner's Contract Value that is held in the Fixed Account
will accrue interest at an effective annual rate of at least 3%. When any part
of a Purchase Payment is allocated to the Fixed Account or an amount is
transferred into the Fixed Account, an interest rate will be assigned to that
amount. That rate will be guaranteed by the Company for one year from the
receipt of the Purchase Payment or transferred amount. At the end of that year,
 
                                       11
<PAGE>   18
 
a new interest rate, which will be guaranteed by the Company for at least one
year, will be assigned to that Purchase Payment or transferred amount and
related earnings. Thereafter, interest rates assigned to that amount and to
subsequent Purchase Payments or to subsequent transferred amounts allocated to
the Fixed Account will be similarly guaranteed for successive periods of at
least one year. Therefore, different interest rates may apply to different
amounts in the Fixed Account depending upon when the amount was initially
allocated by the Owner, and the interest rate applicable to any particular
amount may vary over time. The interest rate credited to a Purchase Payment or
transferred amount by the Company may differ from the rate being earned by the
Company's general account and may differ from the interest rates being credited
to other funds in the general account, whether such funds were received at the
same time as the Purchase Payment or transferred amount or at a different time.
In no event will any interest rate credited be less than an effective annual
rate of 3%. The amount of an Owner's Fixed Account Value and the amount of
interest credited will be included in statements sent to Contract Owners.
 
                                  THE CONTRACT
PURCHASE OF A CONTRACT
 
     GENERAL
 
     The Company offers Contracts only in states in which it has received the
necessary regulatory approvals to do so. Contracts may be Qualified or
Non-Qualified. Qualified Contracts are accorded special federal income tax
treatment under the Code. Generally, Qualified Contracts may be purchased only
in connection with plans which qualify under Sections 401, 403(b), 408 or 457 of
the Code. Qualified Contracts contain provisions restricting the timing and
amount of payments to and distributions from such Contracts. See "Federal Income
Taxation."
 
     MINIMUM/MAXIMUM INVESTMENTS
 
     The purchase of a Non-Qualified Contract requires a minimum initial
Purchase Payment of $10,000. The minimum initial Purchase Payment for a
Qualified Contract is $1,000 or $50 if payments will be made under an automatic
or scheduled installment plan. Subsequent Purchase Payments under both types of
Contracts must be at least $100 (at least $50 if made under an automatic or
scheduled installment plan), and may be made at any time. The maximum cumulative
total of all Purchase Payments under any Contract may not exceed $500,000
without prior approval by the Company. If no Purchase Payments have been
received for two full years and both (a) the total Purchase Payments less any
partial withdrawals and (b) the Contract Value are less than $2,000, the Company
requires that the deficiency be paid within 14 days of notice to the Owner. If
it is not paid, the Company will terminate the Contract and pay the Surrender
Value to the Owner.
 
     PURCHASE PROCEDURE
 
     To purchase a Contract, the purchaser must submit the initial Purchase
Payment and the completed Application Form in good order to the Company at the
Special Markets Service Center. The Contract becomes effective on the Contract
Date, which is stated on page 3 of the Contract, and generally is within one
business date after the Valuation Date on which the initial Purchase Payment and
the Application Form are received in good order at the Special Markets Service
Center. Any such receipt must be effected by 4:00 p.m. Eastern Time on a
Valuation Date; if later, the effective date of the Contract will be the
following Valuation Date. Purchase Payments will be allocated among the
Sub-Accounts (and, if applicable, the Fixed Account) according to the
instructions of the Owner. See "Allocation of Purchase Payments." If an
incomplete Application Form is received, the Company will request additional
information to complete the application. If the Application Form remains
incomplete for five business days after its receipt, the Company will return the
initial Purchase Payment unless the purchaser consents to a delay.
 
     ISSUE AGE LIMITS
 
     The maximum age at issue of the proposed Owner depends on the Death Benefit
Option selected. See "Death Benefit." Owners electing the Standard Death Benefit
may not be older than 85. Owners electing the
 
                                       12
<PAGE>   19
 
Annual Step-up Death Benefit or the 6% Accumulating Death Benefit may not be
older than 75. The proposed Annuitant, whether the Owner or another, must be no
older than 85.
 
FREE LOOK PRIVILEGE
 
     A Contract may be returned for a refund within 10 days after the Owner
receives it (the "FREE LOOK PERIOD"). If the Owner chooses not to retain the
Contract, it must be returned to the Company at the Special Markets Service
Center within the free look period. In such circumstances, the Company will
cancel the Contract and refund promptly an amount that in most cases will be
equal to the Owner's Contract Value, plus any amount deducted from the initial
Purchase Payment prior to allocation to the Sub-Accounts or the Fixed Account.
The laws of certain states require the Company to return other amounts to Owners
pursuant to the free look privilege; in such states, such amounts will be
returned. Similarly, the laws of certain states require a free look period
longer than 10 days; Owners living in such states will have a free look period
conforming to applicable state law.
 
ALLOCATION OF PURCHASE PAYMENTS
 
     Allocation of the initial Purchase Payment will be made according to the
instructions given by the Owner on the Application Form. Each allocation must be
in whole percentages of at least 5%, and the sum of the allocation percentages
must equal 100%. Absent written instructions from the Owner, subsequent Purchase
Payments will be allocated in the same manner as the most recent written
allocation, or the initial allocation, if unchanged. Contract Owners should
periodically review their allocations under the Contract in light of market
conditions and their own financial objectives.
 
     For all Purchase Payments allocated to Sub-Accounts (other than the initial
such payment, which is allocated as of the Contract Date), Accumulation Units
will be credited at the Accumulation Unit Value calculated as of the close of
business on the Valuation Date such Purchase Payment is received in good order
by the Company at the Special Markets Service Center if received before 4:00
p.m. Eastern Time on such Valuation Date. For payments received after such time,
Accumulation Units will be credited at the Accumulation Unit Value calculated as
of the next following Valuation Date. The number of Accumulation Units for each
Sub-Account of the Variable Account is determined by dividing the amount of the
Purchase Payment allocated to the Sub-Account by the Accumulation Unit Value for
the Sub-Account as of the close of business on the Valuation Date on which the
Company is deemed to have received the Purchase Payment. The Accumulation Unit
Value for each Sub-Account was set arbitrarily at $10 when the first Portfolio
interest was purchased by the Sub-Account. Thereafter, Accumulation Unit Value
fluctuates from day to day depending upon the investment performance of the
Portfolio in which the Sub-Account is invested.
 
ACCUMULATION UNIT VALUE
 
     The following material describes the procedures used to calculate
Accumulation Unit Value for, respectively, the five Sub-Accounts (Emerging
Growth, International Equity, Balanced, Income Opportunity and Standby Income)
that invest in Portfolios of the VI Trust and the two Sub-Accounts (Growth &
Income and Bond) that invest in Portfolios of the SA Trust. The procedures do
not produce different results. Rather, they reflect different accounting
treatment at the Portfolio level, with interests in the VI Trust being
calculated on a per share basis and interests in the SA Trust being calculated
on a percentage basis.
 
     ACCUMULATION UNIT VALUE OF VIT SUB-ACCOUNTS
 
     The value of an Accumulation Unit at the close of any Valuation Period is
determined for each Sub-Account that invests in a VIT Portfolio (a "VIT
SUB-ACCOUNT") by multiplying the Accumulation Unit Value of the Sub-Account at
the close of the immediately preceding Valuation Period by the "VIT NET
INVESTMENT FACTOR" (described below). Depending upon investment performance of
the VIT Portfolio in which the Sub-Account is invested, the Accumulation Unit
Value may increase or decrease.
 
                                       13
<PAGE>   20
 
     The VIT Net Investment Factor for each VIT Sub-Account, for any Valuation
Period, is determined by dividing (a) by (b) and subtracting (c) from the
result, where:
 
     (a) is:
 
        (1) the net asset value per share of the corresponding VIT Portfolio at
            the end of the current Valuation Period, plus
 
        (2) the per share amount of any dividend or capital gain distribution
            made by the VIT Portfolio on shares held in the Sub-Account if the
            "ex-dividend" date occurs during the current Valuation Period, plus
            or minus
 
        (3) a per share charge or credit for any taxes reserved, which are
            determined by the Company to have resulted from the investment
            operations of the Sub-Account during the current Valuation Period;
 
     (b) is the net asset value per share of the corresponding VIT Portfolio
         determined at the end of the immediately preceding Valuation Period;
 
       and
 
     (c) is a factor representing the charges deducted from the Sub-Account on a
         daily basis for the daily portion of the annual Mortality and Expense
         Risk Charge (1.20% to 1.40%, depending on the Death Benefit Option
         selected) and the annual Contract Administration Charge (0.15%).
 
     ACCUMULATION UNIT VALUE OF GROWTH & INCOME AND BOND SUB-ACCOUNTS
 
     The value of an Accumulation Unit at the close of any Valuation Period is
determined for the Growth & Income and Bond Sub-Accounts by multiplying the
Accumulation Unit Value at the close of the immediately preceding Valuation
Period by the "SAT NET INVESTMENT FACTOR" (described below). Depending upon
investment performance of the SAT Portfolio in which the Sub-Account is
invested, the Accumulation Unit Value may increase or decrease.
 
     The SAT Net Investment Factor for each of the Growth & Income and Bond
Sub-Accounts for any Valuation Period is equal to one plus the net result of (a)
divided by (b) where:
 
     (a) is the accrued gain or loss in the Sub-Account for the Valuation
         Period, including investment income, capital gains and losses, adjusted
         by:
 
        (1) charging the Sub-Account a dollar amount representing the portion of
            the annual Mortality and Expense Risk Charge (1.20% to 1.40%,
            depending on the Death Benefit Option selected) and the annual
            Contract Administration Charge (0.15%) that is allocable to the
            Sub-Account for the Valuation Period, and
 
        (2) charging or crediting the Sub-Account for any tax charge or tax
            credit determined by the Company to have resulted from the
            investment operations of the Sub-Account during the Valuation
            Period;
 
      and
 
     (b) is the value of the Sub-Account as of the close of the immediately
         preceding Valuation Period.
 
FIXED ACCOUNT VALUE
 
     Fixed Account Value is calculated on a daily basis, and consists of (i) the
sum of all Purchase Payments allocated to the Fixed Account, plus (ii) any
Variable Account Value transferred to the Fixed Account, plus (iii) interest
credited by the Company to the Fixed Account, less (iv) any amounts transferred
from the Fixed Account to the Variable Account, less (v) any amounts withdrawn
for charges or deductions, or in connection with any surrenders or partial
withdrawals (which include Surrender Charges, if any, and any share of the
Contract Maintenance Charge taken from the Fixed Account). See "The Fixed
Account."

DOLLAR COST AVERAGING
 
     A Contract Owner may direct the Company, at any time prior to the Income
Date, automatically to transfer specified dollar or percentage amounts (or
earnings amounts) from the Fixed Account or from the Standby Income Sub-Account
to other Sub-Accounts on a monthly or quarterly basis. This automatic transfer,
known as "DOLLAR COST AVERAGING", may be selected by a Contract Owner for a
period of at least 12 months. The minimum Dollar Cost Averaging transfer is
$200, with a minimum allocation per Sub-Account of 5% of the total amount
transferred. Dollar Cost Averaging is available only if the Contract Value is at
least $10,000. All Dollar Cost Averaging transfers for all Contracts will be
made effective on the monthly or quarterly anniversary of the Contract Date, at
the election of the Owner. Contract Owners may elect to participate in Dollar
Cost Averaging by notifying the Company in writing. Forms for this purpose are
available from the Special Markets Service Center. Dollar Cost Averaging will
terminate when any of the following occurs: (1) the number of designated
transfers has been completed; (2) the portion of the Contract Value in the Fixed
Account or in the Standby Income Sub-Account is insufficient to complete the
next scheduled transfer; (3) the Contract Owner requests termination in writing;
or (4) the Contract is terminated. There is no charge at this time for Dollar
Cost Averaging, but the Company reserves the right to charge a fee for this
service. The Company also reserves the right to terminate Dollar Cost Averaging,
on a prospective basis, upon 30 days' written notice to Contract Owners.
 
TRANSFERS
 
     Subject to the conditions described below, an Owner may transfer all or
part of the Contract Value among the Sub-Accounts and the Fixed Account.
 
     The minimum transfer amount is $250. Transfers among Sub-Accounts other
than by Dollar Cost Averaging may be made once every thirty days, and not less
than 5% of the total amount transferred can be directed to any other
Sub-Account. An Owner may only transfer from one or more Sub-Accounts to the
Fixed Account once each Contract Year, and from the Fixed Account to one or more
Sub-Accounts once each Contract Year (except in the case of Dollar Cost
Averaging). When transferring from the Fixed Account, the amount of the transfer
(excluding Dollar Cost Averaging transfers) is limited to a maximum of 25% of
the Fixed Account Value. The Company currently imposes no charges for any such
transfer, but reserves the right to modify availability of and conditions for
transfers at any time, including the right to charge transfer fees.
 
     The Company will effect transfers pursuant to proper written or telephone
instructions received at the Special Markets Service Center which clearly
specify the requested changes. Requests received in good order by the Company at
the Special Markets Service Center by 4:00 p.m. Eastern Time on any Valuation
Date will be effected that day; requests received after that time will be
effected on the next Valuation Date.
 
     The Company will not honor telephone transfer instructions unless proper
authorization has been provided either (i) in the completed Application Form, or
(ii) in a properly completed telephone transfer authorization form. If the
proper authorization is on file at the Special Markets Service Center, requests
for transfers may be made by calling 1-800-669-2796 (press 2) between 8:00 a.m.
and 4:00 p.m. Eastern Time on any Valuation Date. Such telephone transfer
request must include a precise identification of the Owner's Contract and social
security number. A personal identification number ("PIN") also may be required.
The Company will accept telephone requests for transfers from any person
presenting the required information and claiming to be the Owner. All or part of
any telephone conversation relating to transfer instructions may be recorded by
the Company.
 
     Telephone transfer instructions apply only to previously invested Purchase
Payments and may not be employed to change the investment allocation of future
Purchase Payments under the Contract. Allocation of future Purchase Payments can
be changed only by proper written request. See "Allocation of Purchase
Payments."
 
     The Company will not be liable for following instructions received by
telephone that it reasonably believes to be genuine. The Company has established
certain procedures, some of which are described above, to confirm that telephone
instructions are genuine. If it does not follow reasonable procedures, it may be
liable for any losses due to unauthorized or fraudulent instructions.
 
                                       15
<PAGE>   22
 
     The Company reserves the right to modify, suspend or discontinue the
telephone transfer privilege at any time and without prior notice.
 
SURRENDERS AND PARTIAL WITHDRAWALS
 
     While the Contract is in force and prior to the Income Date or the death of
the Owner, the Company will, upon proper written notification by the Owner,
allow the Owner to surrender all, or withdraw part, of the Contract Value, less
any Surrender Charge and any applicable Contract Maintenance Charge and premium
taxes. See "Surrender Charge." A withdrawal may not be less than $250, and it
may not reduce the Contract Value to less than $2,000. For information regarding
amounts that may be withdrawn without any Surrender Charge (so called "free"
amounts), see "Surrender Charge -- 'Free Amounts'."
 
     Any amount withdrawn will result in the liquidation of Accumulation Units
from each applicable Sub-Account and liquidation of value from the Fixed Account
in the ratio that the value of each Sub-Account and the Fixed Account bears to
the total Contract Value. The Owner must specify in writing in advance which
Accumulation Units or value are to be liquidated if some other ratio is desired.
 
     All surrenders and partial withdrawals from the Variable Account will be
paid within seven days of receipt of written notification, subject to
postponement of either calculation or payment, or both, for any of the following
reasons:
 
     (1) The New York Stock Exchange is closed other than for customary weekend
         and holiday closings;
 
     (2) Trading on the New York Stock Exchange is restricted;
 
     (3) An emergency exists as a result of which disposal of securities is not
         reasonably practicable or it is not reasonably practicable to fairly
         determine the value of the net assets of the Variable Account;
 
     (4) The SEC, by order, permits postponement of payments for the protection
         of security holders; or
 
     (5) The request for surrender or withdrawal is not made in writing or is
         not received in good form (i.e., accurate, complete and
         understandable).
 
     Applicable regulations of the SEC shall determine whether the conditions
prescribed in (2) and (3) exist.
 
     Payments resulting from surrenders or withdrawals from the Fixed Account
may be deferred for up to six months.
 
     Since the Owner assumes the investment risk with respect to amounts held in
the Sub-Accounts and because certain surrenders and partial withdrawals are
subject to a Surrender Charge, the total amount paid upon surrenders and partial
withdrawals under the Contracts may be more or less than the Purchase Payments
made.
 
     Tax Matters.  The Internal Revenue Code imposes a penalty tax equal to 10%
of the amount treated as taxable income on most surrenders and partial
withdrawals made from Contracts prior to the Contract Owner or the Annuitant (in
the case of a Qualified Contract) reaching age 59 1/2. See "Tax Treatment of
Withdrawals -- Non-Qualified Contracts" and -- Qualified Contracts."
 
     SYSTEMATIC WITHDRAWALS
 
     A Contract Owner may elect in writing to withdraw from the Contract a
specified dollar amount of at least $100 on a monthly, quarterly, semiannual or
annual basis. If such systematic withdrawals exceed 10% of Contract Value in any
year, a Surrender Charge may apply. The systematic withdrawals will be
accomplished by liquidating, on a pro rata basis, Accumulation Units from all
Sub-Accounts to which Contract Value is allocated and value from the Fixed
Account.
 
     Alternatively, the Owner may elect to withdraw future earnings only, with
no specified dollar amount, on a monthly, quarterly, semiannual or annual
schedule. Under this election, Accumulation Units and value from the Fixed
Account representing only such income earned on the Contract will be liquidated
to satisfy the systematic withdrawals, and no Surrender Charges will apply to
such liquidations.
 
                                       16
<PAGE>   23
 
     An Owner may discontinue systematic withdrawals at any time by notifying
the Company in writing. The Company reserves the right to discontinue offering
systematic withdrawals, on a prospective basis, upon 30 days' written notice to
Contract Owners. Any such discontinuation would not affect systematic withdrawal
plans already in operation. The Company also reserves the right to assess a
processing fee for this service. Based upon the Company's present costs, the
Company does not expect that such fee would exceed $5.00 per transaction.
 
     Tax Matters.  The Internal Revenue Code imposes a penalty tax equal to 10%
of the amount treated as taxable income on most surrenders and partial
withdrawals made from Contracts prior to the Contract Owner or the Annuitant (in
the case of a Qualified Contract) reaching age 59 1/2. See "Tax Treatment of
Withdrawals -- Non-Qualified Contracts" and -- Qualified Contracts."
 
SELECTION OF INCOME PAYMENT OPTION
 
     INCOME DATE SELECTION
 
     Unless otherwise required by plan documents or current tax law, or unless
otherwise indicated by the Owner, the Income Date is the later of the Contract
Anniversary on or following the Annuitant's 80th birthday and the 10th Contract
Anniversary (see Page 3 of the Contract). The Income Date can be changed to any
date by written request to the Company, if such written request is received on
or prior to the scheduled Income Date. See "Tax Treatment of Withdrawals --
Non-Qualified Contracts" and -- Qualified Contracts."
 
     INCOME PAYMENT OPTIONS
 
     Annuity payments will be made to the payee(s) designated by the Owner. If
no payee is designated, the Owner will be the payee. The Owner may change
payee(s) at any time by written notice to the Company.
 
     The Owner may apply the Surrender Value less any applicable premium tax
under any one of the income payment options specified in the Contract and
described below. A change of income payment option is permitted on or prior to
the Income Date upon written notice to the Company. In the absence of an
election, annuity payments will be made in accordance with Option 2, described
below, with monthly payments guaranteed for ten years and payable for life.
Annuity payments will be made monthly (or, if requested, quarterly, semiannually
or annually) except that: (i) proceeds of less than $1,000 shall be paid in a
single sum and (ii) the Company may change the frequency of payment to avoid
periodic payments of less than $50.
 
     The income payment options currently available under the Contract are
described below. Unless limited in any jurisdiction by applicable state
insurance laws, each of the plans is available under Non-Qualified Contracts.
 
     Option 1.  Fixed Period -- Paid in equal monthly payments for the number of
                years selected, but not more than 30 years.
 
     Option 2.  Life with Guaranteed Period -- Paid in equal monthly payments
                during the lifetime of the Annuitant. The Company guarantees
                payments for either 10 years or 20 years, and for as long as the
                Annuitant lives. The amount of the monthly payment is based on
                the Annuitant's sex and age on the date of the first payment and
                on the number of years for which payments are guaranteed.
 
     Option 3.  Fixed Amount -- Paid in equal monthly installments of $5 or more
                for each $1,000 applied until the full amount, with compound
                interest at not less than 3% a year, is used up.
 
     Option 4.  Life Only -- Paid in equal monthly installments during the
                lifetime of the Annuitant. The amount depends on the age and sex
                of the Annuitant on the date of first payment. Payments will
                cease upon the death of the Annuitant.
 
     Option 5.  Joint and Survivor -- Paid in equal monthly payments during the
                lifetimes of the Annuitant and another designated person. Upon
                the death of either, payments will continue to the survivor at a
                preselected percentage (100%, 75%, 66 2/3% or 50%) of the
                original payment. The amount of each monthly payment depends the
                sexes and ages of both persons on the date of the first payment,
                and the pre-selected percentage for continuing payments.
 
                                       17
<PAGE>   24
 
     All options are also available under Qualified Contracts, but Options 1, 2
and 3 are available only if any period certain does not extend beyond the life
expectancy of the Annuitant.
 
     Under Options 1 and 3 payments may be commuted (i.e., paid in a lump sum);
under Options 2, 4 and 5 they may not.
 
DEATH BENEFIT
 
     If the Owner dies before the Income Date, the Company will pay to the
Beneficiary an amount equal to the greatest of (i) the Death Benefit Option
(defined below) previously selected by the Owner, (ii) the sum of all Purchase
Payments less any amounts withdrawn (including any surrender charges) and (iii)
the Contract Value determined as of the Benefit Determination Date. The amount
so determined is the "DEATH BENEFIT". No Surrender Charge is made if payment of
the Death Benefit results from the death of the Owner prior to the Income Date.
 
     DEATH BENEFIT OPTIONS
 
     Prior to the issuance of the Contract, the Owner may select from among
three death benefit options (the "DEATH BENEFIT OPTIONS"). The option selected
may not be changed after the Contract is issued. The three options are the
Standard Death Benefit, the Annual Step-Up Death Benefit and the 6% Accumulating
Death Benefit. The characteristics of the three Death Benefit Options are as
follows:
 
          The "Standard Death Benefit" will apply if the Owner does not select
     one of the other two options. This option provides no special benefit.
     Accordingly, the benefit paid will be limited to the greater of the other
     two values that are considered in all cases, that is, the Contract Value
     and an amount equal to the sum of all Purchase Payments less any amounts
     withdrawn.
 
          The "Annual Step-Up Death Benefit" equals the greatest Adjusted
     Contract Value (defined below) for each Contract Anniversary up to and
     including the Contract Anniversary immediately following the Owner's 80th
     birthday, calculated as of the Benefit Determination Date. For this
     purpose, "ADJUSTED CONTRACT VALUE" means an amount equal to the Contract
     Value on the relevant Contract Anniversary increased by all Purchase
     Payments and less a reduction for all partial withdrawals made between such
     Contract Anniversary and the Benefit Determination Date. The reduction for
     partial withdrawals is made in the same proportion that the Contract Value
     was reduced on the date of withdrawal.
 
          The "6% Accumulating Death Benefit" is based upon the initial Purchase
     Payment, which is increased by (i) interest earned at the Death Benefit
     Accumulation Rate (as defined below) and (ii) additional Purchase Payments,
     and is decreased by any partial withdrawals made during the life of the
     Contract. The benefit continues to accumulate until it equals the Maximum
     Accumulated Death Benefit (defined below). The "DEATH BENEFIT ACCUMULATION
     RATE" is a weighted average rate based on the allocation of Contract Value.
     For amounts allocated to the Fixed Account, the Standby Income Sub-Account
     and the Bond Sub-Account, the rate is the lesser of six percent per annum
     or the actual rate at which the account has accumulated (or decreased) over
     the relevant period. The rate for amounts allocated to all other Sub-
     Accounts is a fixed six percent per annum. The "MAXIMUM ACCUMULATED DEATH
     BENEFIT" is initially equal to two times the initial Purchase Payment made
     on the Contract Date. It is increased by two times any additional Purchase
     Payments and reduced, in accordance with a formula, for amounts that are
     later withdrawn. The amount of reduction will be made (i) dollar-for-dollar
     to the extent that the withdrawal is taken from earnings (earnings being
     the excess of Contract Value over aggregate Purchase Payments less partial
     withdrawals) and (ii) in proportion to the reduction in Contract Value to
     the extent that the withdrawal is taken from Purchase Payments. For further
     information concerning the Maximum Accumulated Death Benefit, see the
     Statement of Additional Information.

</TABLE>
 
DEATH PROVISIONS
 
     DEATH OF OWNER
 
     If the Contract is owned by a sole Owner who dies prior to the Income Date,
the Beneficiary will be paid the Death Benefit. The sole Owner's estate will be
the Beneficiary if no Beneficiary designation is in effect, or if the designated
Beneficiary has predeceased the Owner. Any Death Benefit will be paid to the
Beneficiary either in one sum or under one of the payment options of the
Contract. If the Company does not receive Death Benefit payment instructions
within 60 days of receipt of satisfactory proof of death, it reserves the right
to make payment of the Death Benefit in a lump sum.
 
     Payments must be completed by December 31 of the fifth calendar year
following the year of the Owner's death, except that, if the Beneficiary is an
individual and so elects, the payments may be made (i) over the life of the
Beneficiary or (ii) according to a fixed schedule which does not extend beyond
the life expectancy of the Beneficiary.
 
     If an Owner dies on or after the Income Date, any payments that remain to
be made must be made at least as rapidly as under the Income Payment Option in
effect on the date of the Owner's death.
 
     DEATH OF ANNUITANT
 
     If the Annuitant dies prior to the Income Date, and a Contingent Annuitant
has been named, the Contingent Annuitant becomes the Annuitant (unless the Owner
is not an individual, in which case the Death Benefit becomes payable). If there
is no Contingent Annuitant when the Annuitant dies prior to the Income Date, the
Owner will become the Annuitant. The Owner may designate a new Annuitant within
60 days of the death of the Annuitant.
 
     If there is no Contingent Annuitant when the Annuitant dies prior to the
Income Date and the Owner is not a natural person, the Beneficiary will be paid
the Death Benefit then due. The Beneficiary will be as provided in the
Beneficiary designation then in effect. If no Beneficiary designation is in
effect, or if there is no designated Beneficiary living, the Owner will be the
Beneficiary. If the Annuitant was the sole Owner and there is no Beneficiary
designation, the Annuitant's estate will be the Beneficiary.
 
     Regardless of whether a Death Benefit is payable, if the Annuitant dies and
any Owner is not a natural person, such death will be subject to distribution
rules imposed by Federal tax law.
 
     If the Annuitant dies after the Income Date, the benefits, if any,
remaining to be paid will depend upon the income payment option in effect. See
"Income Payment Options."
 
                                    CHARGES
 
     All charges under the Contract are described below.
 
PREMIUM TAXES
 
     Certain states or other governmental entities impose premium taxes, with
rates that range up to as much as 3.5% of the Purchase Payment. Some states
assess the tax at the time Purchase Payments are made, and others assess at the
time annuity payments begin. The Company will pay the premium tax at the time
imposed by
 
                                       19
<PAGE>   26
 
applicable law. The Company reserves the right to deduct for the tax, however,
at the time the tax is paid, at the time the Contract is surrendered or amounts
are withdrawn, when the Death Benefit is paid or when the annuity payments
begin.
 
OTHER TAXES
 
     The Company reserves the right to deduct the amount of certain taxes (other
than premium taxes) that it may have to pay. See "Federal Income Tax
Information."
 
ADMINISTRATIVE CHARGES
 
     The Company incurs costs in establishing and maintaining the Contracts, and
in maintaining records and systems and issuing reports to Owners. The
administrative charges discussed below have been established at the levels
indicated to reimburse the Company for its expected actual costs of
administering the Contracts over time.
 
     CONTRACT MAINTENANCE CHARGE
 
     On each Contract Anniversary before the Income Date, an annual Contract
Maintenance Charge is deducted from the Contract Value of any Contract having a
Contract Value of less than $50,000. The Contract Maintenance Charge is also
deducted on any date not a Contract Anniversary on which the Owner fully
surrenders the Contract, or on the Income Date. The Contract Maintenance Charge
for the first ten Contract Years is $40. After the tenth Contract Anniversary
the charge for any Contract having a Contract Value of less than $50,000 is the
lesser of (a) $40 and (b) 0.14% of the Contract Value. This charge will be
deducted by liquidating on a pro-rata basis Accumulation Units from all
Sub-Accounts to which Contract Value is allocated and value from the Fixed
Account. In states in which it has received regulatory approval, the Company may
waive, reduce or eliminate the Contract Maintenance Charge for certain Qualified
Contracts.
 
     CONTRACT ADMINISTRATION CHARGE
 
     On each Valuation Date, the Company deducts from the Accumulation Unit
Value a Contract Administration Charge equal to a percentage of such value that
is the daily equivalent of an effective annual rate of 0.15%. This charge is
assessed only against the Sub-Accounts of the Variable Account and is not
imposed against the portion, if any, of the Contract Value allocated to the
Fixed Account.
 
MORTALITY AND EXPENSE RISK CHARGE
 
     As compensation for its assumption of mortality and expense risks, the
Company deducts from the Accumulation Unit Value a Mortality and Expense Risk
Charge equal to a percentage of such value that is determined by the Death
Benefit Option selected by the Owner. If the Owner selects the Standard Death
Benefit, the charge is 1.20% of the assets in the respective Sub-Accounts. If
the Owner selects one of the other Death Benefit Options, the charge will be
1.30% for the Annual Step-Up Death Benefit and 1.40% for the 6% Accumulating
Death Benefit. This charge is not imposed against any portion of the Contract
Value allocated to the Fixed Account. The Company bears a "MORTALITY RISK"
because the Company is taking the risk that its actuarial estimate of mortality
rates may prove inaccurate. This would result if the Owner lives longer than
expected, or if the Owner dies prior to the Income Date at a time when the Death
Benefit guaranteed by the Company is higher than the Contract Value. The Company
bears an "EXPENSE RISK" because the costs of issuing and administering Contracts
may be greater than expected when setting the administrative charges. Of the
total charge, 0.35% is for assuming the expense risk and the balance, ranging
from 0.85% to 1.05%, is for assuming the mortality risk. The Company may realize
a gain from the charge for these risks to the extent that the charge is not
needed to provide for benefits and expenses under the Contracts.
 
     If the Surrender Charge is insufficient to cover the distribution expenses
of the Contracts, the deficiency will be met from the Company's general account,
including amounts derived from the Mortality and Expense Risk Charge.
 
                                       20
<PAGE>   27
 
SURRENDER CHARGE
 
     Surrenders and Withdrawals.  Since no deduction for a sales charge is made
from the Purchase Payments, a Surrender Charge is imposed on certain surrenders
and partial withdrawals to cover expenses relating to the promotion, sale and
distribution of the Contracts. The Surrender Charge is assessed on each Purchase
Payment (except for certain "free" amounts described below) from which amounts
are being withdrawn and is based upon the number of years since the Purchase
Payment was received. For purposes of computing the Surrender Charge (except for
systematic withdrawals of future earnings only), amounts will be deemed to be
withdrawn from Purchase Payments first, and in the order they were received,
before any amounts in excess of Purchase Payments are withdrawn from the
Contract Value. To the extent permitted by applicable law, no Surrender Charge
shall be assessed (i) at the death of the Owner, or (ii) if, at the time of
withdrawal, the Owner or the Annuitant has been confined to a long-term care
facility or hospital (as defined in the Contract) for at least 30 days or (iii)
with respect to Contracts in 403(b) plans, in the event of a disability (as
defined by the Social Security Administration) of the Owner/Annuitant, hardship
(as defined in the plan) of the Owner/Annuitant or any required minimum
distributions.
 
     The Surrender Charge applies to Purchase Payments (except for certain
"free" amounts described below) as follows:

     The Company reserves the right to reduce or eliminate the Surrender Charge
when Contracts are sold to a trustee, employer or similar entity pursuant to a
retirement plan or when Contracts are otherwise sold to a group such that the
Company saves sales expenses (except in states where such reduction or
elimination is prohibited). Whether the Surrender Charge will be reduced or
eliminated depends upon a number of factors, including the size of the group,
the total amount of Purchase Payments received from the group and the manner in
which they are made, the type of plan involved, the costs to the Company of
distribution and other circumstances, all as evaluated at the sole discretion of
the Company. In no event will reduction or elimination of the Surrender Charge
be permitted where such reduction or elimination will unfairly discriminate
against any person or where prohibited by state law.
 
     Annuitization (Commencement of Annuity Payments). A Surrender Charge is
also imposed if annuity payments begin during the first seven Contract Years.
However, if the Contract Owner elects an Income Date that is at least two years
after the Contract Date and selects an income payment option with at least five
years of level payments, the Surrender Charge will be waived. If the Owner later
(but within seven years after the last Purchase Payment) elects, where
permitted, to take the commuted value of the remaining payments, a Surrender
Charge will be imposed at the rates shown in the above table, calculated as of
the date of commutation.
 
     "Free" Amounts. Any Purchase Payments received more than seven years prior
to the withdrawal (less any amounts previously withdrawn) may be withdrawn free
of any Surrender Charge. In addition, for Purchase Payments that have been in
the Contract for less than eight years, the Owner may withdraw, without a
Surrender Charge, up to 10% of the Contract Value. This free withdrawal
privilege is non-cumulative and is available each Contract Year. Free withdrawal
amounts are deemed withdrawn on a first-in, first-out basis; that is,
withdrawals are deemed to come from the oldest Purchase Payments first. With
respect to Contracts owned by
 
                                       21
<PAGE>   28
 
charitable remainder trusts, the Contract Owner may, in states where regulatory
approval has been received, withdraw without Surrender Charge the amount by
which the Contract Value at any given time exceeds the aggregate Purchase
Payments.
 
EXPENSES OF VIT PORTFOLIOS AND SAT PORTFOLIOS; EXPENSE CAPS
 
     Each VIT Portfolio and each SAT Portfolio incurs various operating
expenses. For the VIT Portfolios these expenses are more fully described in the
prospectus for the VIT Portfolios. For the Growth & Income and Bond Portfolios,
they are described in Part II of this Prospectus. All such expenses are borne
indirectly by Owners in that they reduce the net asset value of the Portfolios.
 
     Under Sponsor Agreements with the VI Trust and the SA Trust, the Sponsor
has agreed to reimburse each Portfolio for the amounts by which total operating
expenses, on an annual basis, exceed the following percentages of the average
daily net assets of the various Portfolios:

     Operating expenses, for purposes of expense reimbursement, include fees of
the Advisor, fees of the Administrator, amortization of organizational expenses,
legal and accounting fees and Sponsor fees, but do not include interest, taxes,
brokerage commissions and other portfolio transaction expenses, capital
expenditures and extraordinary expenses. The Sponsor Agreements may be
terminated by the Sponsor as of the end of any calendar quarter after December
31, 1998 upon not less than 30 days prior written notice. The Sponsor's
agreement to reimburse a Portfolio also terminates as to a Portfolio if the
Sponsor ceases to be the investment advisor to that Portfolio. See "Sponsor."
Under the Sponsor Agreements, the Sponsor is entitled to an annual fee of 0.20%
of average daily net assets, but the Sponsor has waived such fees through April
30, 1999.
 
                               OTHER INFORMATION
DISTRIBUTION OF THE CONTRACTS
 
     Contracts are distributed through Touchstone Securities, Inc. (the
"DISTRIBUTOR"), which is a wholly-owned subsidiary of IFS Financial Services,
Inc. ("IFS"), in turn a wholly-owned subsidiary of the Company. The principal
business address of the Distributor is 311 Pike Street, Cincinnati, Ohio 45202.
The Distributor will pay sales commissions to those individuals or entities who
sell the Contracts. Commissions may be calculated as a percentage of the
Purchase Payments received or as a trail commission that is determined as a
percentage of the Contract Value. In addition, under certain circumstances the
Distributor may pay production bonuses which take into account, among other
things, the total Purchase Payments that have been made under Contracts
associated with the broker-dealer. Additional payments may be made for other
services not directly related to the sale of the Contracts. These expenses are
not passed on to the Owner of the Contract except to the extent absorbed by any
Mortality and Expense Risk Charges or by Surrender Charges on Purchase Payments
withdrawn during the first seven years following their receipt. See "Surrender
Charge" and "Mortality and Expense Risk Charge."
 
STATEMENTS TO CONTRACT OWNERS
 
     Prior to the Income Date, a confirmation of each Purchase Payment and
certain other transactions, such as transfers and partial withdrawals, will be
sent to the Owner.
 
                                       22
<PAGE>   29
 
     At least once in each Contract Year prior to the Income Date, each Owner
will be sent a statement that includes the Variable Account Value and the Fixed
Account Value as of a date not more than four months prior to the mailing date
of such statement. Each Owner whose Contract Value is measured in any part by
Accumulation Units in the Variable Account also will receive semiannual reports
containing financial statements for the Separate Account 1. At least one such
report in each year will be accompanied by a list of portfolio securities of
each of the Portfolios underlying the Sub-Accounts and any other information
required by applicable law or regulation.
 
ADJUSTMENT OF UNITS AND VALUES
 
     The Company reserves the right to change the number and value of the
Accumulation Units credited to any Contract, without the consent of the Owner or
any other person, provided strict equity is preserved and the change does not
otherwise affect the benefits, provisions or investment return of the Contract.
 
VOTING RIGHTS
 
     Prior to the Income Date the Company will vote shares of each VIT Portfolio
and the interest in each SAT Portfolio owned by the Variable Account according
to instructions received from Owners whose Contract Value includes Accumulation
Units in the Variable Account. However, if the 1940 Act or any related
regulations or interpretations should change and the Company decides it may be
permitted to vote shares (or interests) of the Portfolios in its own right, it
may do so.
 
     Persons entitled to give voting instructions will be determined as of the
record date for meetings of shareholders of any or all of the Portfolios. Prior
to the Income Date, the Owner has the right to direct the vote by the Company at
such meetings of that portion of the shares of any VIT Portfolio (or interest in
any SAT Portfolio) held in the Sub-Account that is attributable to the Owner's
Contract.
 
     The Company calculates that portion of the shares (interest, in the case of
the SA Trust) in the Portfolio that the Owner may direct the Company to vote by
applying the Owner's percentage interest, if any, in a particular Sub-Account to
the total number of shares (interest, in the case of the SA Trust) attributable
to such Sub-Account as of the record date. Fractional votes will be counted. The
Company reserves the right to modify the manner in which it calculates the
weight given to voting instructions where such change is necessary to comply
with then-current federal regulations or interpretations of those regulations.
 
     The Company will determine 90 days or less before the applicable meeting
the number of shares in each VIT Portfolio (or, in the case of the SA Trust, the
portion of the interest in each SAT Portfolio) that each Contract Owner can
instruct the Company to vote. At least 14 days before such meeting, the Company
will mail such person materials enabling him or her to instruct the Company how
to vote.
 
     If voting instructions are not received from an Owner, the Company will
vote the shares of the VI Trust (or interest in the SAT Portfolio) attributable
to such Owner in the same proportion as the voting instructions which are
received from other Contract Owners. The Company also will vote shares or
interest it holds in the Sub-Accounts that are not attributable to Contract
Owners in the same manner. Under certain circumstances, the Company may be
required by state regulatory authorities to disregard voting instructions. This
could happen if such instructions would change the sub-classification or
investment objectives of the Portfolios, or result in approval or disapproval of
an investment advisory contract.
 
     Under federal regulations, the Company also may disregard instructions to
vote for Owner-initiated changes in investment policies or the investment
advisor if the Company disapproves of the proposed changes. The Company would
disapprove of a proposed change only if it were contrary to state law,
prohibited by state regulatory authorities or if the Company concluded that the
change would result in overspeculative or unsound investment practices. If the
Company disregards voting instructions, it will include a summary of its actions
in the next report to Contract Owners.

SUBSTITUTED SECURITIES
 
     Shares of the VIT Portfolios or interests in the SAT Portfolios may not
always be available for purchase by the Sub-Accounts of the Variable Account, or
the Company may decide that further investment in any such shares or interest or
in any such Portfolios is no longer appropriate in view of the purposes of the
Variable Account. In either event, shares of or an interest in another open-end
investment company or unit investment trust may be substituted both for the
Portfolio shares or interest already purchased by the corresponding Sub-Accounts
and/or as the security to be purchased in the future, provided that these
substitutions have been approved by the Securities and Exchange Commission. In
the event of any substitution pursuant to this provision, the Company may make
an appropriate endorsement to the Contract to reflect the substitution.
 
                           OTHER CONTRACT PROVISIONS
MISSTATEMENT OF AGE OR SEX
 
     If the age or sex of the Annuitant is misstated to the Company, the Company
will change any benefits under the Contract to those which the proceeds would
have purchased had the correct age and sex been stated. If the misstatement is
not discovered until after annuity payments have started, any overpayments will
be charged, with compound interest, against subsequent payments. Any amount the
Company owes as the result of underpayments will be paid, with compound
interest, in a lump sum.
 
ASSIGNMENT
 
     An Owner may assign a Non-Qualified Contract in writing, but may not assign
a Qualified Contract except as may be allowed under applicable law and the
documents governing the plan. The Company will not be bound by any assignment
until written notice of the assignment is received and recorded at the Special
Markets Service Center. The rights of the Owner and any Beneficiary will be
affected by an assignment, and the Company disclaims any responsibility for the
validity or tax consequences of any assignment.
 
LOANS
 
     Loans may be permitted under Qualified Contracts purchased by the Company
in connection with a plan established under Section 403(b). Plan documents also
must permit such loans. Loans are not permitted under any other type of
Contract.
 
NO DIVIDENDS
 
     The Contracts are "non-participating." That means that they do not provide
for dividends. Investment results under the Contracts are reflected in benefits.
 
                         FEDERAL INCOME TAX INFORMATION
 
     PROSPECTIVE OWNERS SHOULD CONSULT THEIR OWN TAX ADVISORS PRIOR TO
PURCHASING A CONTRACT.
 
     THE FOLLOWING DISCUSSION IS NOT INTENDED AND SHOULD NOT BE RELIED UPON AS
TAX ADVICE, BUT MERELY AS A SYNOPSIS OF CERTAIN FEDERAL INCOME TAX LAWS.
ALTHOUGH THE FOLLOWING DISCUSSION IS BASED UPON THE COMPANY'S UNDERSTANDING OF
FEDERAL INCOME TAX LAWS AS CURRENTLY INTERPRETED, THERE IS NO GUARANTEE THAT
THOSE LAWS AND INTERPRETATIONS WILL NOT CHANGE. THE DISCUSSION DOES NOT TAKE
INTO ACCOUNT STATE OR LOCAL TAX LAWS WHICH MAY AFFECT THE PURCHASE OF A CONTRACT
OR THE BENEFITS PAID OUT UNDER A CONTRACT, AND DOES NOT CONSIDER FEDERAL ESTATE
AND GIFT TAXES AND STATE AND LOCAL ESTATE, INHERITANCE AND OTHER SIMILAR TAXES
WHICH WILL DEPEND UPON THE INDIVIDUAL SITUATION OF EACH OWNER OR BENEFICIARY.
 
QUALIFICATION AS AN "ANNUITY CONTRACT"
 
     The following discussion is based upon the Company's assumption that the
Contract will be treated as an "annuity contract" under the Code. The Company
does not guarantee the tax status of any Contract. A purchaser bears the
complete risk that the Contract may not be treated as an "annuity contract"
under federal
 
                                       24
<PAGE>   31
 
income tax laws. Disqualification of the Contract as an annuity contract
generally would result in imposition of federal income tax to the Owner with
respect to yearly earnings allocable to the Contract prior to the receipt of
payments under the Contract.
 
     DIVERSIFICATION
 
     Section 817(h) of the Code imposes certain diversification standards on the
underlying assets of all variable annuity contracts. The Code generally provides
that a variable contract will not be treated as an annuity contract for any
period (and any subsequent period) for which the investments are not, in
accordance with regulations prescribed by the United States Treasury Department
("TREASURY DEPARTMENT"), adequately diversified. The Code contains a safe harbor
provision which provides that variable contracts such as the Contracts meet the
diversification requirements if, as of the end of each quarter, the underlying
assets meet the diversification standards prescribed elsewhere in the Code for
an entity to be classified as a regulated investment company and no more than
fifty-five percent (55%) of the total assets consist of cash, cash items, U.S.
government securities and securities of other regulated investment companies.
 
     In March 1989, the Treasury Department issued regulations (Treas. Reg.
Section 1.817-5), which established diversification requirements for the
investment portfolios such as the Portfolios underlying variable contracts such
as the Contracts. The regulations amplify the diversification requirements for
variable contracts set forth in the Code and provide an alternative to the safe
harbor provision described in Section 817(h) of the Code. Under the Regulations,
an investment portfolio will be deemed adequately diversified if: (1) no more
than 55% of the value of the total assets of the investment portfolio is
represented by any one investment; (2) no more than 70% of the value of the
total assets of the investment portfolio is represented by any two investments;
(3) no more than 80% of the value of the total assets of the investment
portfolio is represented by any three investments; and (4) no more than 90% of
the value of the total assets of the investment portfolio is represented by any
four investments.
 
     The Code provides that for purposes of determining whether or not the
diversification standards imposed on the underlying assets of variable contracts
by Section 817(h) of the Code have been met, "each United States Government
agency or instrumentality shall be treated as a separate issuer."
 
     The Variable Account, through each of the VIT Portfolios and each of the
SAT Portfolios, intends to comply with the diversification requirements of the
Code and the regulations. The Advisor has agreed to manage the Portfolios so as
to comply with such requirements.
 
     EXCESSIVE CONTROL
 
     The Treasury Department has from time to time suggested that guidelines may
be forthcoming under which a variable annuity contract will not be treated as an
annuity contract for tax purposes if the owner of the contract has excessive
control over the investments underlying the contract (i.e., by being able to
transfer values among Sub-Accounts with only limited restrictions). If a
variable contract is not treated as an annuity contract, the owner of such
contract would be considered the owner of the assets of a separate account, and
income and gains from that account would be included each year in the owner's
gross income. No such guidelines have been issued to date.
 
     The issuance of such guidelines, or regulations or rulings dealing with
excessive control issues, might require the Company to impose limitations on an
Owner's right to transfer all or part of the Contract Value among the
Sub-Accounts and the Fixed Account or to make other changes in the Contract as
necessary to attempt to prevent an Owner from being considered the owner of any
assets of the Variable Account. The Company therefore reserves the right to make
such changes. It is not known whether any such guidelines, regulations or
rulings, if adopted, would have retroactive effect.
 
     REQUIRED DISTRIBUTIONS
 
     Additionally, in order to qualify as an annuity contract under the Code, a
Non-Qualified Contract must meet certain requirements regarding distributions in
the event of the death of the Owner. In general, if the
 
                                       25
<PAGE>   32
 
Owner dies before the entire value of the Contract is distributed, the remaining
value of the Contract must be distributed according to provisions of the Code.
Upon the death of an Owner prior to commencement of annuity payments, the
amounts accumulated under a Contract must be distributed within five years, or,
if distributions to a designated beneficiary within the meaning of Section 72 of
the Code (a "DESIGNATED BENEFICIARY") begin within one year of the Owner's
death, distributions are permitted over a period not extending beyond the life
(or life expectancy) of the designated beneficiary. The above rules are modified
if the designated beneficiary is the surviving spouse. The surviving spouse is
not required to take distributions from the Contract under the above rules as a
beneficiary and may continue the Contract and take distributions under the above
rules as if the surviving spouse was the original Owner. If distributions have
begun prior to the death of the Owner, such distributions must continue at least
as rapidly as under the method in effect at the date of the Owner's death
(unless the method in effect provides that payments cease at the death of the
Owner).
 
     For Qualified Contracts issued in connection with tax-qualified plans and
individual retirement annuities, the plan documents and rules will determine
mandatory distribution rules. However, under the Code, distributions from
Contracts issued under Qualified Plans (other than individual retirement
annuities and certain governmental or church-sponsored Qualified Plans) for
employees who are not 5% owners of the sponsoring employer generally must
commence no later than April 1 of the calendar year following the calendar year
in which the employee terminates employment or reaches age 70 1/2, whichever is
later, and such distributions must be made over a period that does not exceed
the life expectancy of the employee or the joint and last survivor life
expectancy of the employee and a designated beneficiary. Distributions from
Contracts issued under individual retirement annuities or to 5% owners of the
sponsoring employer from Contracts issued under Qualified Plans (other than
certain governmental or church-sponsored Qualified Plans) must commence by April
1 of the calendar year after the calendar year in which the individuals reach
age 70 1/2 even if they have not terminated employment. A penalty tax of 50% is
imposed on any amount by which the required minimum distribution in any year
exceeds the amount actually distributed.
 
     If the Contract is a Qualified Contract issued in connection with an
individual retirement annuity, a SIMPLE account, or a plan which qualifies under
Sections 403(b), 408 or 457 of the Code, the Company will send a notice to the
Owner when the Annuitant reaches age 70 1/2. The notice will summarize the
required minimum distribution rules and advise the Owner of the date that such
distributions must begin from the Qualified Contract or other individual
retirement annuities of the Owner. The Owner has sole responsibility for
requesting distributions under the Qualified Contract or other individual
retirement annuities that will satisfy the minimum distribution rules. In the
case of a distribution from a Contract issued under a Qualified Plan which
qualifies under Section 401 of the Code, the Company will not send a notice when
the Annuitant reaches age 70 1/2, and the Owner (or the employer sponsoring the
Qualified Plan) has sole responsibility for requesting distributions under the
Qualified Contract that will satisfy the minimum distribution rules.
 
     MULTIPLE CONTRACTS
 
     The Code provides that multiple non-qualified annuity contracts which are
issued within a calendar year period to the same contract owner by one company
or its affiliates are treated as one annuity contract for purposes of
determining the tax consequences of any distribution. Such treatment may result
in adverse tax consequences, including accelerated taxation of the gain deemed
distributed from such combination of contracts. Owners should consult a tax
advisor prior to purchasing more than one non-qualified annuity contract in any
calendar year period.
 
FEDERAL INCOME TAXATION
 
     GENERAL
 
     The Company is taxed as a life insurance company under the Code. For
federal income tax purposes, neither Separate Account 1 nor the Variable Account
is a separate entity from the Company and their operations form a part of the
Company.
 
     Section 72 of the Code governs taxation of annuities in general. Except as
described below for Owners who are not natural persons, an Owner is not taxed on
increases in the value of the Contract when those increases
 
                                       26
<PAGE>   33
 
occur. Instead, an Owner is taxed only when distribution occurs, either in the
form of a lump sum payment or as annuity payments under the income payment
option selected. For a lump sum payment received as a total surrender (total
redemption), the recipient is taxed on the portion of the payment that exceeds
the cost basis of the Contract. For Non-Qualified Contracts, this cost basis is
generally the sum of the Purchase Payments, while for a Qualified Contract there
may be no cost basis in the Contract within the meaning of Section 72 of the
Code. The taxable portion of the lump sum payment is taxed at ordinary income
tax rates.
 
     For annuity payments from Non-Qualified Contracts, a fixed portion of each
payment is excludable from gross income as a tax-free recovery of the Owner's
Purchase Payments (if any), and the balance is taxed at ordinary income tax
rates. The excludable portion can be determined by dividing (i) the Owner's
Purchase Payments (in the case of Non-Qualified Contracts only, as adjusted for
any period-certain or refund guarantee), less any withdrawals from those
Purchase Payments, by (ii) the number of years over which it is anticipated that
the annuity will be paid. The method of determining the number of years over
which payments are anticipated is different for Qualified and Non-Qualified
Contracts. If annuity payments continue beyond the anticipated number of years,
such payments will be fully taxable.
 
     Owners who are not natural persons generally must include in income any
increase in the excess of the Contract's Value over the "investment in the
contract" during the taxable year. As a result, Contracts used in connection
with unfunded deferred compensation plans of private employers (sometimes called
"top hat" plans) generally are currently subject to income tax on such increase
in value. There are some exceptions to this rule, including an exception for
Contracts owned by certain tax-qualified plans. A prospective Owner that is not
a natural person may wish to discuss availability of these exceptions with its
own tax advisor.
 
     Annuity payments or other amounts received under all Contracts are subject
to income tax withholding under the Code unless the recipient elects not to have
taxes withheld. However, annuity payments to former employees under deferred
compensation plans pursuant to Section 457 of the Code are subject to income tax
withholding as if such payments are wages. Amounts so withheld will vary among
recipients depending upon the tax status of the recipient and the type of
payment.
 
     Owners, Annuitants and Beneficiaries under the Contracts should seek
financial advice about the tax consequences of any withdrawals or other
distributions.
 
     TAX TREATMENT OF ASSIGNMENTS
 
     An assignment or pledge of a Contract may be a taxable event. Owners should
therefore consult their tax advisors should they wish to assign their Contracts.
 
     TAX TREATMENT OF WITHDRAWALS -- NON-QUALIFIED CONTRACTS
 
     Section 72 of the Code governs treatment of all payments (including
withdrawals of Contract Value) from annuity contracts. Applied to a Contract, it
provides that if the Contract Value exceeds the aggregate Purchase Payments
made, any payment that is not received as an annuity payment will be treated as
coming first from earnings and then, only after the earnings portion is
exhausted, as coming from the principal. If the Contract contains investments in
the Contract made prior to August 14, 1982, special taxation rules apply to such
withdrawals and related earnings. These special rules provide that any amount
withdrawn that is not received as an annuity payment will be treated as coming
first from principal and then, only after the principal portion is exhausted, as
coming from earnings. Withdrawn earnings are includable in gross income.
 
     Section 72 further provides that a ten percent (10%) penalty will apply to
the income portion of amounts received other than: (a) on or after the date the
taxpayer reaches age 59 1/2; (b) on or after the death of the Contract Owner;
(c) if the taxpayer is totally disabled (as defined in Section 72(m)(7) of the
Code); (d) in a series of substantially equal periodic payments made not less
frequently than annually for the life (or life expectancy) of the taxpayer or
for the joint lives (or joint life expectancies) of the taxpayer and the joint
annuitant; (e) from a Contract issued under a plan that qualifies for favorable
federal income tax treatment under Sections 401(a), 403(a), or 403(b) of the
Code or that is an individual retirement account or individual retirement
annuity; (f) amounts attributable to investment in the Contract prior to August
14, 1982; (g) from a
 
                                       27
<PAGE>   34
 
Contract that is issued under a Qualified Plan; (h) under an immediate annuity
within the meaning of Code Section 72(u)(4); or (i) which is purchased by an
employer upon termination of a plan described in Section 401(a) or 403(a) of the
Code and is held by the employer until the employee separates from service (some
of the above exceptions may not apply to Contracts issued as Non-Qualified
Contracts).
 
     The above paragraph does not apply to Qualified Contracts. However,
separate withdrawal restrictions and tax penalties and restrictions may apply to
such Qualified Contracts. See "Tax Treatment of Withdrawals -- Qualified
Contracts."
 
     QUALIFIED CONTRACTS AND QUALIFIED PLANS
 
     The Qualified Contracts offered by this Prospectus are designed to be
suitable for use under various types of plans which qualify under Sections 401,
403(b) or 408 of the Code ("QUALIFIED PLANS") and under plans which qualify
under Section 457 of the Code. Because of the minimum purchase payment
requirements, such Contracts may not be appropriate for some retirement plans.
Taxation of participants in each Qualified Plan varies with the type of plan and
terms and conditions of each specific plan.
 
     Owners, Annuitants and Beneficiaries are cautioned that benefits under a
Qualified Plan usually are subject to the terms and conditions of such plan
regardless of the terms and conditions of Qualified Contracts issued pursuant to
such plan. Although the Company provides administration for Qualified Contracts,
it does not provide administrative support for Qualified Plans. Qualified
Contracts may include special provisions restricting Contract provisions that
may otherwise be available and described in this Prospectus. Generally,
Qualified Contracts issued pursuant to Qualified Plans are not transferable
except upon surrender or annuitization. Various penalty and excise taxes may
apply to contributions or distributions made in violation of applicable
limitations. Furthermore, certain withdrawal penalties and restrictions may
apply to surrenders from Qualified Contracts. See "Tax Treatment of Withdrawals
- -- Qualified Contracts."
 
     On July 8, 1983, the Supreme Court decided in Arizona Governing Committee
v. Norris that optional annuity benefits provided under an employer's deferred
compensation plan could not, under Title VII of the Civil Rights Act of 1964,
vary between men and women. Accordingly, Contracts sold by the Company in
connection with Qualified Plans (excluding individual retirement annuities) will
utilize annuity tables which do not differentiate on the basis of sex.
 
     The following are general descriptions of the types of Qualified Plans with
which the Qualified Contracts may be used. Such descriptions are not exhaustive
and are for general informational purposes only. The tax rules regarding
Qualified Plans are complex, change frequently and will have differing
applications depending on individual facts and circumstances. Each purchaser
should obtain tax advice prior to purchasing a Contract issued under a Qualified
Plan.
 
     SECTION 401 QUALIFIED PENSION OR PROFIT-SHARING PLANS
 
     Section 401 of the Code permits self-employed individuals (which includes
persons conducting a trade or business through a partnership) to establish
various types of Qualified Plans for themselves and their employees, commonly
referred to as "H.R. 10" or "Keogh" plans. Section 401 of the Code also permits
corporate employers and certain non-profit organizations to establish various
types of Qualified Plans for employees. These retirement plans may permit the
purchase of the Contracts to provide benefits under the plans. Permissible
contributions to such plans for the benefit of such persons will not be
includable in the gross income of such persons for federal income tax purposes
until distributed from the plans.
 
     The tax consequences to participants may vary depending upon the particular
plan design. However, the Code places limitations and restrictions on all such
plans including on such items as: amounts of allowable contributions; form,
manner and timing of distributions; vesting and nonforfeitability of interests;
nondiscrimination in eligibility and participation; and the tax treatment of
distributions, withdrawals and surrenders. See "Tax Treatment of Withdrawals --
Qualified Contracts" and "Tax Sheltered Annuities -- Withdrawal Limitations."

     SECTION 403(b) PLANS
 
     Section 403(b) of the Code permits the purchase of "tax-sheltered
annuities" by public schools and certain charitable, educational and scientific
organizations described in Section 501(c)(3) of the Code. These qualifying
employers may make contributions to the Contracts for the benefit of their
employees. Such contributions are not includable in the gross income of
employees for federal income tax purposes until the employees receive
distributions from the Contracts. The amount of contributions to a tax-sheltered
annuity is limited to certain maximums imposed by the Code. Contributions also
may need to comply with nondiscrimination rules, which may further limit
contributions for highly compensated employees. Furthermore, the Code sets forth
additional restrictions governing such items as transferability, distributions
and withdrawals. See "Tax Treatment of Withdrawals -- Qualified Contracts."
 
     Section 403(b) Plans are qualified employer plans covered under Section
72(p) of the Code concerning loans from plans. Under the Contract, an Owner may,
subject to certain requirements, receive loans from a Contract that is issued as
a 403(b) tax sheltered annuity beginning 30 days after date of issue.
 
     LOANS FROM SECTION 403(b) PLANS
 
     With respect to Section 403(b) Plans, the Contract provides for loans that
conform to the specific terms set forth in the Contract and Code Section 72(p).
In general, the maximum amount and other terms and conditions of loans from a
Contract are determined as though the Contract was a qualified plan covered
under Title I of ERISA. Among other things, the Contract specifically requires
that each such loan must be a minimum of $1,000 and that the maximum term for
repayment of loans (other than residential purchase loans) is 5 years, at an
interest rate comparable to that charged by commercial lenders for similar
loans. Residential purchase loans may be repaid over a 15-year period.
 
     A Contract cannot be surrendered or annuitized while a Contract loan is
outstanding, unless the Contract Value can be reduced by the outstanding loan
balance plus interest and such reduction satisfies Section 403(b)(11) of the
Code if applicable.
 
     INDIVIDUAL RETIREMENT ANNUITIES
 
     Section 408(b) of the Code permits eligible individuals to contribute to an
individual retirement program known as an "Individual Retirement Annuity"
("IRA"). Under applicable limitations, certain amounts may be contributed to an
IRA which may be deductible from the individual's gross income for federal
income tax purposes. Tax-deductible contributions to individual retirement
annuities under Section 408(b) of the Code are limited to the lesser of $2,000
or 100% of compensation includable in federal taxable gross income for
individuals who (i) are not (and whose spouses are not) active participants in
another tax-qualified retirement plan, (ii) are active participants in another
such plan but are unmarried and have adjusted gross incomes of $25,000 or less,
(iii) are active participants (or have spouses who are active participants) in
another tax-qualified retirement plan but are married, file a joint tax return
and have adjusted gross incomes of $40,000 or less, or (iv) are not active
participants (even if they have spouses who are active participants) in another
tax-qualified retirement plan but are married and file a separate federal income
tax return. Individuals who are active participants in other retirement plans
and whose adjusted gross income exceeds the above $25,000 or $40,000 limits, as
applicable, by less than $10,000 are entitled to make deductible contributions
in proportionately reduced amounts. Persons who are active participants in
another qualified retirement plan, are married, file a separate federal income
tax return, and have adjusted gross incomes of $10,000 or less are entitled to
make deductible contributions in reduced amounts.
 
     Subject to the rules in the prior paragraph about persons who are active
participants in other tax-qualified retirement plans, a deductible contribution
also may be made to an IRA for a spouse who receives little or no compensation
during the tax year such as a spouse who does not work outside the home (a
"nonworking spouse"). The nonworking spouse must file a joint federal income tax
return with his or her working spouse for the year to be eligible to contribute
to an IRA. The maximum deductible contribution for the nonworking spouse is the
lesser of $2,000 or the total of the compensation includable in the nonworking
spouse's own federal
 
                                       29
<PAGE>   36
 
taxable gross income (if any) plus the compensation includable in the federal
taxable gross income of his or her working spouse minus the working spouse's IRA
contribution for the year.
 
     An individual may make nondeductible contributions to an IRA equal to
$2,000 minus the limit on deductible contributions to an IRA with respect to
that individual for the year.
 
     Under certain conditions, distributions from other individual retirement
accounts, individual retirement annuities or Qualified Plans may be rolled over
or transferred to an IRA on a tax-deferred basis. IRAs are subject to
limitations on eligibility, contributions, transferability and distributions.
See "Tax Treatment of Withdrawals -- Qualified Contracts." Sales of Contracts
for use with IRAs are subject to special requirements imposed by the Code,
including the requirement that certain informational disclosure be given to
persons desiring to establish an IRA. Purchasers of Contracts to be qualified as
Individual Retirement Annuities should obtain tax advice as to the tax treatment
and suitability of such an investment.
 
     SIMPLIFIED EMPLOYEE PENSION PLANS
 
     Employers may establish what is known as a simplified employee pension plan
("SEP") under Section 408(k) of the Code. Employer contributions to a SEP can be
invested in an individual retirement annuity selected by a participant in the
SEP. Contributions generally must be made as a uniform percentage of employee
compensation and are excluded from gross income of the employee for federal
income tax purposes. Employer contributions to a SEP cannot exceed the lesser of
$30,000 or 15% of an employee's eligible compensation (which may not exceed
$160,000 for the year 1997, indexed to reflect certain cost-of-living changes
for 1998 and later years). The Code also permits employees of certain small
employers to have SEP contributions made on the basis of salary reduction if the
SEP was established as a salary reduction SEP no later than December 31, 1996.
Such salary reduction contributions may not exceed $9,500, indexed annually for
inflation.
 
     The tax consequences to participants may vary depending upon the particular
plan design. However, the Code places limitations and restrictions on all such
plans including on such items as: amounts of allowable contributions; form,
manner and timing of distributions; vesting and nonforfeitability of interests;
nondiscrimination in eligibility and participation, and the tax treatment of
distributions, withdrawals and surrenders. See "Tax Treatment of Withdrawals --
Qualified Contracts."
 
     SAVINGS INCENTIVE MATCH PLANS FOR EMPLOYEES (SIMPLE)
 
     Employers which establish Savings Incentive Match Plans for Employees
("SIMPLE" IRAs) under Section 408(p) of the Code may make employee salary
deferral contributions and employer contributions to individual retirement
annuities established for the eligible employees. Employees who have earned or
expect to earn $5,000 or more annually may defer the lesser of $6,000 or 100% of
earned income through a salary deferral arrangement. Employee salary deferrals
are not includable in the employee's federal taxable gross income. The employer
must make a company contribution (not to exceed $6,000 annually) based on one of
two schedules. The schedules are either a dollar for dollar matching
contribution for all employees who make salary deferral contributions based on
the employee's salary deferral up to a maximum of 3% of the employee's
compensation, or a 2% nonelective contribution for all eligible employees based
on compensation (which may not exceed $160,000 for 1997). Employers sponsoring
SIMPLE IRAs may not maintain other qualified retirement plans.
 
     The Code places certain limitations and restrictions on these plans
including: manner and timing of contributions; vesting and nonforfeitability of
interests; nondiscrimination in eligibility and participation; tax treatment of
distributions, withdrawals and surrenders; frequency of notification and
eligibility to participate; and annual employee reporting. See "Tax Treatment of
Withdrawals -- Qualified Contracts."
 
     SECTION 457 -- DEFERRED COMPENSATION PLANS
 
     Under Section 457 of the Code, governmental and certain other tax exempt
employers may establish deferred compensation plans for the benefit of their
employees and may purchase annuity contracts in connection with those plans.
Under such plans, contributions made for the benefit of the employees will not
be includable in the employees' gross income for federal income tax purposes
until distributed from the Plan. If the
 
                                       30
<PAGE>   37
 
program is considered an "eligible deferred compensation plan" under the Code,
an individual generally may contribute, on a tax-deferred basis, the lesser of
$7,500 or 33 1/3% of gross income from the employer, reduced by amounts excluded
from income under Sections 403(b) (tax sheltered annuities), 402(e)(3) (elective
salary deferrals under Sections 401(k) or 403(b) plans), 402(h)(1)(B) (elective
salary deferrals under Simplified Employee Pensions) or 402(k) (SIMPLE IRAs) of
the Code or for which a deduction is allowed under Section 501(c)(18) (for
certain "employee pay-all" plans created before June 25, 1959) for the taxable
year. Amounts so deferred may be used by the employer to purchase Contracts
pursuant to this Prospectus.
 
     Under a Section 457 plan that is not a governmental plan, all the plan
assets, including any Contract, must remain solely the property of the employer
subject only to the claims of the employer's general creditors until such time
as made available to the participant or beneficiary. The employee has no present
rights or vested interest in the Contract and is entitled to payment only under
the terms of the plan.
 
     Under a governmental Section 457 plan that is maintained by a state, a
political subdivision of a state, or any agency or instrumentality of a state or
political subdivision, all assets of a Section 457 plan must be held in a trust,
a custodial account or an annuity contract for the exclusive benefit of
participants and their beneficiaries.
 
     Distributions from such plans generally are not permitted prior to
termination of employment except in cases of unforeseeable emergencies (as
defined in Treas. Reg. Section 1.457-2(b)(4)).
 
     TAX TREATMENT OF WITHDRAWALS -- QUALIFIED CONTRACTS
 
     The discussion in the following paragraph applies to Qualified Plans other
than IRAs. It does not apply to Section 457 plans.
 
     Distributions from Qualified Contracts purchased under Qualified Plans (but
not from IRAs) that are "eligible rollover distributions" are subject to certain
"direct rollover" and federal income tax withholding rules. The Qualified Plan
is required to give the Contract Owner, Annuitant or Beneficiary (as applicable)
the choice of having payments that are eligible rollover distributions paid
either as (a) a "direct rollover" to an individual retirement account or an
individual retirement annuity (an "INDIVIDUAL RETIREMENT ARRANGEMENT") or to
certain other types of Qualified Plans, or (b) a payment to the Contract Owner,
Annuitant or Beneficiary. Nonspouse Beneficiaries cannot elect direct rollovers.
If a direct rollover is chosen, the payment will be made directly to the
individual retirement arrangement or other Qualified Plan, and will not be
subject to federal income tax in the year the direct rollover is made, but will
be taxed later when it is taken out of the individual retirement arrangement or
other Qualified Plan. If a payment to the Contract Owner, Annuitant or
Beneficiary is chosen, he or she will receive only 80% of the payment because
the Qualified Plan administrator is required to withhold 20% of the payment and
send it to the Internal Revenue Service to be credited against federal income
taxes. Also, the Contract Owner, Annuitant or Beneficiary will be taxed on the
payment for the year it is made unless he or she rolls it over to an individual
retirement arrangement or certain other types of Qualified Plans within 60 days
of receiving the payment. Nonspouse Beneficiaries cannot make such rollovers. If
the Contract Owner, Annuitant or Beneficiary wants to roll over 100% of a
payment, he or she must find other funds to replace the 20% that was withheld.
Distributions are not "eligible rollover distributions" and cannot be paid as a
direct rollover if they represent the return of "after-tax" employee
contributions, are part of a series of payments made for a period of ten years
or more, to the extent the distributions are "required minimum distributions"
that are made after age 70 1/2 and are required by law, or are made for certain
other reasons. The administrator of the Qualified Plan will provide additional
information about these tax rules when a distribution is made.
 
     Distributions from Qualified Contracts purchased under Qualified Plans that
are not rolled over to an individual retirement arrangement or another Qualified
Plan (or are not eligible to be rolled over) are taxable as ordinary income,
except to the extent allocable to an employee's after-tax contributions. If an
employee or the Beneficiary receives from a Qualified Plan (not including
distributions from an individual retirement account, individual retirement
annuity or tax-sheltered annuity) a "lump sum distribution" as defined in
Section 402(d)(4) of the Code, the taxable portion of the distribution may be
subject to special tax treatment. For most individuals receiving lump sum
distributions after age 59 1/2 and on or before December 31, 1999, the tax rate
may be determined under five-year income averaging provisions of the Code. Those
who reached age 50 on or before January 1, 1986 instead may elect to use a
ten-year income averaging. In addition, such individuals
 
                                       31
<PAGE>   38
 
may elect capital gains treatment for the taxable portion of a lump sum
distribution attributable to years of service before 1974.
 
     Section 72(t) of the Code imposes a 10% penalty tax on the taxable portion
of any distribution from Qualified Plans and IRAs, including Contracts issued in
connection with plans that are qualified under Code Sections 401, 403(b), 408(a)
and 408(b). To the extent amounts are not includable in gross income because
they have been properly rolled over (as direct rollovers or as rollovers of
other payments) to an individual retirement arrangement or to another eligible
Qualified Plan, no tax penalty will be imposed. The tax penalty will not apply
to the following distributions: (a) distributions made on or after the date on
which the Contract Owner or Annuitant (as applicable) reaches age 59 1/2; (b)
distributions following the death or disability of the Contract Owner or
Annuitant (as applicable) (disability is defined in Section 72(m)(7) of the
Code); (c) distributions that are part of substantially equal periodic payments
made not less frequently than annually for the life (or life expectancy) of the
Contract Owner or Annuitant (as applicable) or the joint lives (or joint life
expectancies) of such Contract Owner or Annuitant (as applicable) and the
designated beneficiary (provided that if the Qualified Plan is other than an
IRA, distributions do not begin before the Contract Owner or Annuitant separates
from service); (d) for Qualified Plans other than IRAs, distributions to a
Contract Owner or Annuitant (as applicable) who has separated from service after
attaining age 55; (e) distributions made to the Contract Owner or Annuitant (as
applicable) to the extent such distributions do not exceed the amount allowable
as a deduction under Code Section 213 to the Contract Owner or Annuitant (as
applicable) for amounts paid during the taxable year for medical care; (f) for
Qualified Plans other than IRAs, distributions made to an alternate payee
pursuant to a qualified domestic relations order; and (g) distributions to
unemployed individuals for health insurance premiums under certain conditions.
 
     Distributions from a Qualified Contract issued in connection with a
Qualified Plan or an IRA generally must commence by April 1 of the calendar year
after the calendar year in which the Contract Owner or Annuitant reaches age
70 1/2 (or, if later, by April 1 of the calendar year after the calendar year in
which he or she terminates employment in the case of a Qualified Plan but not in
the case of an IRA), and must be made in minimum annual amounts determined under
rules issued pursuant to the Internal Revenue Code. See "Required
Distributions." Distributions from a Qualified Contract issued in connection
with an IRA and distributions to 5% owners of the sponsoring employer from
Contracts issued under Qualified Plans (other than certain governmental or
church-sponsored Qualified Plans) must commence by April 1 of the calendar year
after the calendar year in which the Contract Owner or Annuitant reaches age
70 1/2, even if he or she has not terminated employment.
 
     Other rules apply to a Qualified Contract issued in connection with a
Qualified Plan or an IRA to determine when and how required minimum
distributions must be made in the event of the death of the Contract Owner or
Annuitant. The plan or IRA documents will contain such rules. In addition, if
the Contract Owner's or Annuitant's surviving spouse is the beneficiary of the
interest in the Qualified Plan or the IRA, the surviving spouse may be able to
elect to defer the commencement of distributions past the commencement date that
otherwise would apply, to roll over a distribution to the surviving spouse's own
individual retirement arrangement or to treat an IRA as his or her own.
 
     Distributions from a Contract issued in connection with a Section 457 Plan
generally must meet the same rules as distributions from Qualified Plans. See
"Required Distributions." However, in the case of a distribution from such a
Contract which does not begin before the death of the Contract Owner or
Annuitant, distributions must be made over a period not exceeding fifteen years
(or the life expectancy of the surviving spouse if that spouse is the
beneficiary).
 
     Under certain conditions, distributions from other IRAs and other Qualified
Plans may be rolled over or transferred on a tax-deferred basis into an IRA or
another Qualified Plan. Persons seeking to roll over distributions in such a
manner should obtain tax advice as to the limitations imposed by the Code on
such rollovers.
 
     Because contributions to a SIMPLE IRA are placed in individual retirement
annuities, many of the IRA rules apply to SIMPLE IRAs. In addition, during the
first two years after the individual first participates in any salary reduction
arrangement that is part of a SIMPLE IRA, any amounts distributed from the
SIMPLE IRA are
 
                                       32
<PAGE>   39
 
subject to a 25% early withdrawal penalty imposed by the IRS unless the
distributions are rolled over to another SIMPLE retirement account or unless one
of the exceptions to the Section 72(t) tax, as discussed above, applies. During
this first two year period, employees may transfer SIMPLE IRAs to other SIMPLE
IRAs without a 25% early withdrawal penalty. Employees who have not reached age
59 1/2 and do not qualify for one of the exceptions to the Section 72(t) tax
must wait two years after first participating in the SIMPLE IRA before
transferring employee and/or employer contributions to other IRAs or IRA
rollover annuities under Section 408(d)(3). After the two-year period, the
normal IRA rules regarding withdrawals apply to SIMPLE IRAs.
 
     TAX-SHELTERED ANNUITIES -- WITHDRAWAL LIMITATIONS
 
     Effective January 1, 1989, the Code limits the withdrawal of amounts
attributable to contributions made pursuant to a salary reduction agreement (as
defined in Section 403(b)(11) of the Code) to circumstances only: (1) when the
Owner attains age 59 1/2; (2) separates from service; (3) dies; (4) becomes
disabled (within the meaning of Section 72(m)(7) of the Code); or (5) in the
case of hardship. However, withdrawals for hardship are restricted to the
portion of the Owner's Contract Value which represents contributions by the
Owner and does not include any investment results. The limitations on
withdrawals apply only to salary reduction contributions made after December 31,
1988 and to income attributable to such contributions and to income attributable
to amounts held as of December 31, 1988. The limitations on withdrawals do not
affect rollovers between certain Qualified Plans. Owners should consult their
own tax counsel or other tax advisor regarding any distributions.
 
                               LEGAL PROCEEDINGS
 
     There are no material legal proceedings, other than ordinary routine
litigation incidental to the businesses of the Company, the Variable Account,
the Distributor, the Advisor or IFS, to which any of these entities is a party
or to which any of their respective property is subject.

              PART II -- DISCUSSION OF SELECT ADVISORS PORTFOLIOS
 
                                    SUMMARY
GENERAL
 
     Select Advisors Portfolios (the "SA TRUST") is a diversified, open-end
management investment company which was organized as a trust under the laws of
the State of New York on February 7, 1994. The SA Trust includes eight separate
portfolios, two of which, the Growth & Income Portfolio and the Bond Portfolio
(sometimes herein called the "SAT PORTFOLIOS"), are discussed in this Part II.
Each of the SAT Portfolios has a different investment objective and different
policies and practices:
 
     GROWTH & INCOME PORTFOLIO has an investment objective of long term capital
     appreciation and dividend income through investment primarily in common
     stocks of high quality companies.
 
     BOND PORTFOLIO has an investment objective of providing a high level of
     current income primarily through investment in investment grade bonds.
 
     The Growth & Income Portfolio and Bond Portfolio of the SA Trust, which are
described in this Part II, may invest up to 5% and 35%, respectively, of their
total assets in non-investment grade bonds. See "Growth & Income Portfolio,"
"Bond Portfolio" and "Medium and Lower Rated ("Junk Bonds") and Unrated
Securities." For further information regarding the investment objectives,
policies and restrictions of each of the SAT Portfolios, see "Investment
Objectives, Policies and Restrictions."
 
RISKS
 
     There are certain risks associated with the investment policies of each SAT
Portfolio. The value of a Sub-Account will fluctuate with the value of the
underlying securities in the corresponding SAT Portfolio in which all of the
Sub-Account's assets are invested. To the extent that a Portfolio invests in
income securities, the market value of those securities will be affected by
general changes in interest rates, which may result in either increases or
decreases in the value of those securities. To the extent that a Portfolio
invests in securities of non-U.S. issuers and foreign currencies, the Portfolio
may face risks that are different from those associated with investment in
domestic securities, including the effect of different economies, change in
relative currency exchange rates, future political and economic developments,
the possible imposition of exchange controls or other governmental confiscation
or restrictions, and less availability of data on companies and the securities
industry as well as less regulation of stock exchanges, brokers and issuers. For
additional information, see "Investment Objectives, Policies and Restrictions"
and "Risk Factors, Restrictions and Investment Techniques."
 
ADVISORS
 
     Each SAT Portfolio is managed by one or more Portfolio Advisors selected by
the Board of Trustees of the SA Trust based on the recommendations of the
Advisor. The Advisor is paid advisory fees for the general management of the SAT
Portfolios. The Portfolio Advisors are paid fees by the Advisor to manage the
assets of each of the SAT Portfolios. See "Management of the Portfolios."
 
     There can, of course, be no assurance that the investment objectives of the
SAT Portfolios can be achieved. Except for certain investment restrictions
designated as fundamental in this Prospectus or the Statement of Additional
Information, the investment objectives and policies of any SAT Portfolio may be
changed by the Trustees of the SA Trust without the approval of the investors in
the respective Portfolio.
 
SUB-ACCOUNTS
 
     Each SAT Portfolio corresponds to a Sub-Account of the Variable Account.
The investment objectives of each Sub-Account are the same as the investment
objectives of its corresponding SAT Portfolio, and each Sub-Account invests the
funds it receives from Contract Owners only in an interest in the corresponding
SAT Portfolio.
 
     Contract Owners electing to allocate a portion of their Purchase Payments
to the Variable Account acquire interests in the Sub-Account(s) which they
select, and do not invest directly in the corresponding SAT
 
                                       34
<PAGE>   41
 
Portfolios. Instead, Purchase Payments of Owners are allocated to the
Sub-Accounts. Each Sub-Account, in turn, holds an interest in the corresponding
SAT Portfolio. See "Purchase Payments." Similarly, Owners that surrender or make
withdrawals from their Contracts do not directly redeem interests in the
Portfolios. See "Surrenders and Partial Withdrawals."
 
     Although Owners who allocate all or any portion of their Purchase Payments
to the various Sub-Accounts do not directly own interests in the SAT Portfolios
or the SA Trust, they do have voting rights in certain circumstances. If at any
time any Sub-Account is requested to vote on a matter regarding the
corresponding SAT Portfolio, the Company will solicit the directions of each
Owner who has allocated Contract Value to such Sub-Account and will cast the
votes of the Sub-Account in accordance with the directions received from such
Owners. See "Voting Rights."
 
OTHER INVESTORS
 
     Owners should be aware that each SAT Portfolio also receives investments
from certain sub-accounts of other variable annuity contracts issued by Separate
Account 1, and may also receive investments from other insurance company
separate accounts of the Company or of other insurance companies. Owners should
be aware that other investors in an SAT Portfolio could control the results of
voting on any matter submitted to investors in that Portfolio. In certain
instances, such as a change in an SAT Portfolio's fundamental policies, it might
be advisable for the affected Sub-Account (subject to receipt of required
approvals) to redeem its investment in the Portfolio. Substantial redemptions
could result in that Portfolio effecting any such redemption by means of a
distribution in kind of Portfolio securities. Any such distribution in kind
could adversely affect the diversification and liquidity of the Sub-Accounts'
investments. In addition, the Sub-Account could incur brokerage and other
transaction costs in order to convert the resulting securities to cash.
 
     As is true with many investments generally, investors in the SAT Portfolios
(including the Sub-Accounts) may be affected by the actions of other large or
controlling investors. For example, the decision of a large investor to redeem
its shares could result in higher operating expenses and a corresponding
reduction in return. Large redemptions could, as well, cause a Sub-Account's
holdings to become less diverse, resulting in increased risk.
 
                              FINANCIAL HIGHLIGHTS
 
     The following table shows ratios to average net assets and other financial
data for each SAT Portfolio for the period indicated and was derived from
financial statements audited by Coopers & Lybrand L.L.P., the SA Trust's
independent accountants, whose report thereon appears in the SA Trust's Annual
Report which is incorporated by reference into the SA Trust's Statement of
Additional Information.

                INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS
 
GROWTH & INCOME PORTFOLIO
 
     The investment objective of the Portfolio is long term capital appreciation
and dividend income by investing primarily in a diversified portfolio of
dividend-paying common stocks, preferred stock and securities convertible into
common stocks. The Portfolio may also purchase such securities which do not pay
current dividends but which offer prospects for growth of capital and future
income. Convertible securities (which may be current coupon or zero coupon
securities) are bonds, notes, debentures, preferred stocks and other securities
which may be converted or exchanged at a stated or determinable exchange ratio
into underlying shares of common stock. The Portfolio may also invest in
non-convertible preferred stocks consistent with the Portfolio's objective.
Under normal conditions, at least 80% of the Portfolio's total assets will be
invested in common stocks and at least 65% of the Portfolio's total assets will
be invested in common stocks that, at the time of investment, will be expected
to pay regular dividends.
 
     The Portfolio will generally invest a majority of its assets in common
stocks of issuers with total market capitalization of $1 billion or greater at
the time of purchase, but may invest in securities of companies having various
levels of market capitalization, including smaller companies whose securities
may be more volatile and less liquid than securities issued by larger companies
with higher levels of net worth. Investments will be in companies in various
industries.
 
     The Portfolio may also invest up to 20% of its total assets in foreign
securities, including securities of foreign issuers in the form of ADRs. The
Portfolio may not invest more than 5% of its total assets in the securities of
companies based in an emerging market. See "Risk Factors, Restrictions and
Certain Investment Techniques -- Foreign Securities" and "-- Risks Associated
with 'Emerging Markets' Securities."
 
     The Portfolio may invest under normal circumstances up to 20% of its total
assets in preferred stocks, convertible preferred stock, bonds, convertible
debentures and other fixed-income instruments (the "Fixed Income Instruments").
Within this 20% limitation, the Portfolio may invest in any combination of Fixed
Income Instruments subject to the following additional limitations: (1) the
Portfolio may invest up to 20% of its total assets in convertible preferred
stock and convertible debentures rated at least Ba by Moody's Investors
Services, Inc. ("Moody's") or BB by Standard & Poor's Rating Service, a division
of McGraw-Hill Companies ("S&P"), (2) the Portfolio may invest up to 20% of its
total assets in non-convertible fixed income instruments rated at least Baa by
Moody's or BBB by S&P and (3) the Portfolio may invest up to 5% of its total
assets in non-convertible debt rated below Baa by Moody's or BBB by S&P. See
"Risk Factors, Restrictions and Certain Investment Techniques -- Convertible
Securities" and "-- Medium and Lower Rated ('Junk Bonds') and Unrated Debt
Securities."
 
     The Portfolio may invest up to 10% of its total assets in real estate
investment trusts ("REITs"), which pool investors' funds for investment
primarily in income-producing real estate or real estate-related loans or
interests. See "Risk Factors, Restrictions and Certain Investment Techniques --
Real Estate Investment Trusts."
 
     The Portfolio may also invest up to 5% of its total assets in Standard &
Poor's Depositary Receipts ("SPDRs") in order to invest uncommitted cash
balances, to maintain liquidity to meet shareholder redemptions, or to minimize
trading costs. SPDRs represent ownership in a unit investment trust that holds a
portfolio of stocks designed to track the performance of the S&P 500 Index.
SPDRs are traded on the American Stock Exchange. See "Risk Factors, Restrictions
and Certain Investment Techniques -- Standard & Poor's Depositary Receipts."
 
                                       36
<PAGE>   43
 
BOND PORTFOLIO
 
     The investment objective of the Portfolio is to provide high current income
primarily through investments in investment grade bonds. Investment grade bonds
are those rated at least Baa by Moody's or BBB by S&P or unrated bonds
considered by the Portfolio Advisor to be of comparable quality. Under normal
circumstances, at least 65% of the value of the Portfolio's total assets will be
invested in bonds or debentures (as described in the first sentence of the next
paragraph). The average maturity of the Portfolio will be between five and
fifteen years. The average maturity of the Portfolio's holdings may be shortened
in order to preserve capital if the Portfolio Advisor anticipates a rise in
interest rates. Conversely, the maturity may be lengthened to maximize returns
if interest rates are expected to decline.
 
     This Portfolio invests in U.S. Treasury obligations, corporate bonds,
debentures, mortgage related securities issued by various governmental agencies,
such as GNMA and government related organizations, such as FNMA and FHLMC,
including collateralized mortgage obligations ("CMOs"), privately issued
mortgage related securities (including CMOs), stripped U.S. Government and
mortgage related securities, non-publicly registered securities, asset backed
securities and Eurodollar certificates of deposit and Eurodollar bonds. It will
also invest in preferred stock. No more than 60% of the Portfolio's total assets
will be invested in mortgage related securities. The Portfolio will not invest
in any bond rated lower than B by S&P or by Moody's. The Portfolio will invest
less than 35% of its assets in U.S. or foreign non-investment grade (or "junk")
bonds and preferred stock. High risk, lower quality debt securities are regarded
as predominantly speculative with respect to the issuer's ability to pay
interest and repay principal in accordance with the terms of the obligation. See
"Medium and Lower-Rated ("Junk Bonds") and Unrated Securities." Up to 20% of the
Portfolio's assets may be invested in fixed-income securities denominated in
foreign currencies. These foreign securities must meet the same rating and
quality standards as the Portfolio's U.S. dollar-denominated investments. See
"Foreign Securities."
 
           SPECIAL INFORMATION CONCERNING HUB AND SPOKE(R) STRUCTURE
 
     The SA Trust is utilizing certain proprietary rights, know-how and
financial services referred to as Hub and Spoke(R) from Signature Financial
Group, Inc.
 
     The Growth & Income and Bond Sub-Accounts seek to achieve their investment
objectives by investing all of their respective assets in the corresponding SAT
Portfolio, each of which is a series of a separate registered investment company
with the same investment objectives as the Sub-Account. In addition to selling
an interest to the corresponding Sub-Account, each SAT Portfolio may sell
interests to certain sub-accounts of other variable annuity contracts issued by
Separate Account 1, and to other separate accounts of the Company or of other
insurance companies. Such investors will invest in an SAT Portfolio on the same
terms and conditions and will pay a proportionate share of that Portfolio's
expenses. However, the other investors investing in the SAT Portfolio are not
required to sell their shares at the same public offering price as the
Sub-Account due to variations in sales commissions and other operating expenses.
Therefore, Owners investing in either the Bond or Growth & Income Sub-Account
should be aware that these differences may result in differences in returns
experienced by investors in the different investment vehicles that invest in a
Portfolio. Such differences in returns are also present in other mutual fund
structures. Information concerning other holders of interests in an SAT
Portfolio is available from the Distributor at (800) 669-2796 (press 3).
 
     The investment objective of an SAT Portfolio may also be changed without
the approval of the investors in the Portfolio, but not without written notice
thereof to the investors in the Portfolio (and notice by the corresponding
Sub-Account to its Owners) thirty days prior to implementing the change. If
there were a change in a Sub-Account's investment objective, Owners should
consider whether the Sub-Account remains an appropriate investment in light of
their then-current financial positions and needs. There can, of course, be no
assurance that the investment objective of any SAT Portfolio will be achieved.
 
     Smaller investors in an SAT Portfolio may be materially affected by the
actions of larger investors in the Portfolio. For example, if a larger investor
withdraws from a Portfolio, the remaining investors may experience higher pro
rata operating expenses, thereby producing lower returns. Additionally, a
Portfolio may become less diverse, resulting in increased portfolio risk.
(However, this possibility exists as well for traditionally structured
 
                                       37
<PAGE>   44
 
investment vehicles which have large or institutional investors.) Also,
investors with a greater pro rata ownership in an SAT Portfolio could have
effective voting control of the operations of the Portfolio. Whenever a
Sub-Account is requested to vote on matters pertaining to the corresponding
Portfolio (other than a vote by the Sub-Account to continue the operation of the
Portfolio upon the withdrawal of another investor in the Portfolio), the Company
will hold a meeting of Owners investing in the Sub-Account and will cast all of
its votes in the same proportion as the votes of these Owners. Owners who do not
vote will not affect the Sub-Account's vote at the Portfolio meeting. The
percentage of a Sub-Account's votes representing Owners not voting will be voted
by the Company in the same proportion as the Sub-Account Owners who do, in fact,
vote. Certain changes in a Portfolio's investment objective, policies or
restrictions might cause a Sub-Account to withdraw its interest in an SAT
Portfolio. Any such withdrawal could result in a distribution "in kind" of
portfolio securities (as opposed to a cash distribution from the Portfolio). If
securities are distributed, a Sub-Account could incur brokerage, tax or other
charges in converting the securities to cash. In addition, the distribution in
kind may result in a less diversified portfolio of investments or adversely
affect the liquidity of a Sub-Account. Notwithstanding the above, there are
other means for meeting shareholder redemption requests, such as borrowing.
 
     For more information about each Portfolio's policies, management and
expenses, see "Investment Objectives, Policies and Restrictions," "Management of
the Portfolios" and "Risk Factors, Restrictions and Investment Techniques." For
more information about each Portfolio's investment restrictions, see the
Statement of Additional Information.
 
                          MANAGEMENT OF THE PORTFOLIOS
GENERAL
 
     The business of the SA Trust is governed by a board of trustees (the
"TRUSTEES" or "BOARD OF TRUSTEES") who are elected by a vote of the investors in
the Portfolios. The Trustees exercise broad supervision over the affairs of the
SA Trust. They have retained the services of the Advisor, a subsidiary of IFS
(in turn a subsidiary of the Company), under terms of an investment advisory
agreement (the "ADVISORY AGREEMENT"), pursuant to which the Advisor has been
engaged as investment advisor to each of the SAT Portfolios. Under terms of the
Advisory Agreement it is the Advisor's responsibility to select, subject to
review and approval by the Trustees, one or more Portfolio Advisors. The Advisor
is responsible for the continuing evaluation, selection and monitoring of the
Portfolio Advisors. In this regard, the Advisor employs the services of
RogersCasey, a research firm specializing in appraisal and comparison of
investment advisers, to assist it in evaluating the Portfolio Advisors and
candidates for those positions. See "Consultant to the Advisor."
 
     Each Portfolio Advisor has discretion, subject to oversight by the
Trustees, to purchase and sell portfolio assets, except as limited by each
Portfolio's investment objectives, policies and restrictions and by specific
investment strategies developed by the Advisor. See "Investment Objectives,
Policies and Restrictions" and "Risk Factors, Restrictions and Investment
Techniques."
 
     For its services, the Advisor receives an advisory fee from each SAT
Portfolio. See "Expenses." A part of the fee paid to the Advisor is used by the
Advisor to pay the advisory fees of the Portfolio Advisors. Such fees are paid
by the Advisor and not by the SAT Portfolio. Any Portfolio Advisor may waive any
or all of such fees. The allocation of the fees paid to the Advisor, showing the
amount received by the Advisor and the amounts paid by it to the two Portfolio
Advisors, is set forth below. Such fees are computed daily and paid monthly at
the annual rate specified below of the value of the average daily net assets of
the SAT Portfolio:

     The Portfolio Advisor for the Bond Portfolio is Fort Washington Investment
Advisors, Inc. ("FORT WASHINGTON"). See "Portfolio Advisors," below. Because
Fort Washington is a subsidiary of Western & Southern and, hence, an affiliate
of the Advisor, the Advisor is subject to a conflict of interest when making
decisions regarding the retention and compensation of that particular Portfolio
Advisor. However, the Advisor's decisions, including the identity of a Portfolio
Advisor and the specific amount of the Advisor's compensation to be paid to the
Portfolio Advisor, are subject to review and approval by a majority of the Board
of Trustees and separately by a majority of such Trustees who are not affiliated
with the Advisor or any of its affiliates.
 
CONSULTANT TO THE ADVISOR
 
     RogersCasey, located at One Parklands Drive, Darien, Connecticut 06820, has
been engaged in the business of rendering portfolio advisor evaluations since
1976. The staff at RogersCasey is experienced in acting as investment
consultants and in developing, implementing and managing multiple portfolio
advisor programs. RogersCasey provides asset management consulting services to
various institutional and individual clients and provides the Advisor with
investment consulting services with respect to development, implementation and
management of the SA Trust's multiple portfolio manager program. RogersCasey is
employed by, and its fees and expenses are paid by, the Advisor (not the SA
Trust). As consultant, RogersCasey provides research concerning registered
investment advisors to be retained by the Advisor as Portfolio Advisors,
monitors and assists the Advisor with the periodic reevaluation of existing
Portfolio Advisors and makes periodic reports to the Advisor and the Board of
Trustees of the SA Trust.
 
PORTFOLIO ADVISORS
 
     The following sets forth certain information about each of the Portfolio
Advisors. The individuals employed by the Portfolio Advisor who are primarily
responsible for the day-to-day investment management of the Portfolio are named
below.
 
     FORT WASHINGTON serves as the Portfolio Advisor to the Bond Portfolio. Fort
Washington is a wholly-owned subsidiary of Western & Southern. Fort Washington
has been registered as an investment advisor under the Investment Advisers Act
of 1940, as amended, (the "ADVISORS ACT") since September 14, 1990. Fort
Washington provides investment advisory services to individual and institutional
clients. As of June 30, 1997, Fort Washington had assets under management of
$8.2 billion. Roger M. Lanham and Brendan White are the individuals primarily
responsible for the day-to-day investment management of the Bond Portfolio. Mr.
Lanham is a CFA and has been with Western & Southern/Fort Washington since 1981.
Mr. White is a CFA and has been with Western & Southern/Fort Washington since
1993. Prior to 1993, Mr. White was with Ohio Casualty Insurance Co. for six
years, managing high yield and mortgage backed assets. Fort Washington's
principal executive offices are located at 420 East Fourth Street, Cincinnati,
Ohio 45202
 
     SCUDDER, STEVENS & CLARK, INC. ("Scudder") serves as Portfolio Advisor to
the Growth & Income Portfolio. All of the outstanding voting and nonvoting
securities of Scudder are held of record by Stephen R. Beckwith, Juris Padegs,
Daniel Pierce, and Edmond D. Villani in their capacity as the representatives of
the beneficial owners of such securities. Scudder has been registered as an
investment advisor under the Advisors Act since 1943. As of July 31, 1997,
Scudder had assets under management in excess of $125 billion. Scudder's
principal executive offices are located at 345 Park Avenue, New York, New York.
 
     On June 26, 1997, Scudder entered in a Transaction Agreement (the
"Transaction Agreement") with Zurich Insurance Company ("Zurich"). Under the
terms of the Transaction Agreement, Zurich will acquire a majority interest in
Scudder, and Zurich Kemper Investments, Inc., a Zurich subsidiary, will become
part of Scuddder. Scudder's name will be changed to Scudder Kemper Investments,
Inc. These transactions are subject to a number of conditions and are expected
to close during the fourth quarter of 1997.
 
     Robert T. Hoffman, Lori Ensinger, Deborah Chaplin, Benjamin W. Thorndike
and Kathleen T. Millard are the individuals primarily responsible for the
day-to-day management of the Growth & Income Portfolio. Mr. Hoffman, Lead
Product Manager, joined Scudder in 1990. He has 13 years of experience in the
investment industry, including several years of pension fund management
experience. Lori Ensinger, Lead Portfolio Manager, focuses on stock selection
and investment strategy. She has worked as a portfolio manager since 1983 and
 
                                       39
<PAGE>   46
 
joined Scudder in 1993. Deborah Chaplin, Portfolio Manager, also focuses on
stock selection and investment strategy. Ms. Chaplin, who joined Scudder in
1996, has over four years of experience as a securities analyst and portfolio

portfolio manager since 1986. Ms. Millard, who joined Scudder in 1991, focuses
on strategy and stock selection.
 
     Scudder may use its affiliated broker to execute portfolio transactions for
the Growth & Income Portfolio provided the commissions paid to the affiliated
broker are reasonable and fair in comparison to commissions paid to other
brokers in connection with comparable transactions. The Board of Trustees
reviews transactions executed through an affiliated broker on a quarterly basis.

              RISK FACTORS, RESTRICTIONS AND INVESTMENT TECHNIQUES
 
TECHNIQUES AND RISK FACTORS
 
     The following are descriptions of certain types of securities invested in
by the SAT Portfolios, certain investment techniques employed by those
Portfolios and risks associated with utilizing either the securities or the
investment techniques.
 
Convertible Securities
 
     Convertible securities may offer higher income than the common stocks into
which they are convertible and include fixed-income or zero coupon debt
securities, which may be converted or exchanged at a stated or determinable
exchange ratio into underlying shares of common stock. Prior to their
conversion, convertible securities may have characteristics similar to both
non-convertible debt securities and equity securities.
 
     While convertible securities generally offer lower yields than
non-convertible debt securities of similar quality, their prices may reflect
changes in the value of the underlying common stock. Convertible securities
entail less credit risk than the issuer's common stock.
 
Derivatives
 
     The Portfolios may invest in various instruments that are commonly known as
derivatives. Generally, a derivative is a financial arrangement, the value of
which is based on, or "derived" from, a traditional security, asset, or market
index. Some "derivatives" such as certain mortgage-related and other
asset-backed securities are in many respects like any other investment, although
they may be more volatile or less liquid than more traditional debt securities.
There are, in fact, many different types of derivatives and many different ways
to use them. There is a range of risks associated with those uses. Futures and
options are commonly used for traditional hedging purposes to attempt to protect
a fund from exposure to changing interest rates, securities prices, or currency
exchange rates and as a low cost method of gaining exposure to a particular
securities market without investing directly in those securities. However, some
derivatives are used for leverage, which tends to magnify
 
                                       40
<PAGE>   47
 
the effects of an instrument's price changes as market conditions change.
Leverage involves the use of a small amount of money to control a large amount
of financial assets, and can in some circumstances, lead to significant losses.
A Portfolio Advisor will use derivatives only in circumstances where the
Portfolio Advisor believes they offer the most economic means of improving the
risk/reward profile of the Portfolio. Derivatives will not be used to increase
portfolio risk above the level that could be achieved using only traditional
investment securities or to acquire exposure to changes in the value of assets
or indexes that by themselves would not be purchased for the Portfolio. The use
of derivatives for non-hedging purposes may be considered speculative. A
description of the derivatives that the Portfolios may use and some of their
associated risks is found below.
 
Foreign Securities
 
     Investing in securities issued by foreign companies and governments
involves considerations and potential risks not typically associated with
investing in obligations issued by the U.S. government and domestic
corporations. Less information may be available about foreign companies than
about domestic companies and foreign companies generally are not subject to
uniform accounting, auditing and financial reporting standards or to other
regulatory practices and requirements comparable to those applicable to domestic
companies. The values of foreign investments are affected by changes in currency
rates or exchange control regulations, restrictions or prohibitions on the
repatriation of foreign currencies, application of foreign tax laws, including
withholding taxes, changes in governmental administration or economic or
monetary policy (in the United States or abroad) or changed circumstances in
dealings between nations. Costs are also incurred in connection with conversions
between various currencies. In addition, foreign brokerage commissions and
custody fees are generally higher than those charged in the United States, and
foreign securities markets may be less liquid, more volatile and less subject to
governmental supervision than in the United States. Investments in foreign
countries could be affected by other factors not present in the United States,
including expropriation, confiscatory taxation, lack of uniform accounting and
auditing standards and potential difficulties in enforcing contractual
obligations and could be subject to extended clearance and settlement periods.
 
Risks Associated with "Emerging Markets" Securities
 
     "Emerging Markets" securities include the securities of issuers based in
some of the world's underdeveloped markets, including Eastern Europe. These
typically include countries where per capita GNP is less than $8,355.
Investments in securities of issuers based in such countries entail all of the
risks of investing in foreign issuers outlined in this section but to a
heightened degree. These heightened risks include: (i) expropriation,
confiscatory taxation, nationalization, and less social, political and economic
stability; (ii) the smaller size of the market for such securities and a low or
nonexistent volume of trading, resulting in a lack of liquidity and in price
volatility; (iii) certain national policies that may restrict a Portfolio's
investment opportunities including restrictions on investing in issuers in
industries deemed sensitive to relevant national interests; and (iv) in the case
of Eastern Europe, the absence of developed capital markets and legal structures
governing private or foreign investment and private property and the possibility
that recent favorable economic and political developments could be slowed or
reversed by unanticipated events.
 
     So long as the Communist Party continues to exercise a significant or, in
some cases, a dominant role in Eastern European countries, investments in such
countries will involve risk of nationalization, expropriation and confiscatory
taxation. The former communist governments of a number of Eastern European
countries expropriated large amounts of private property in the past, and in
many cases without adequate compensation. There is no assurance that such
expropriation will not occur in the future at the hands of either an existing
non-communist regime or upon the return to power of the Communist Party. In the
event of any such expropriation, a Portfolio could lose a substantial portion of
any investments it has made in the affected countries. Finally, even though the
currencies of less developed countries may be convertible into U.S. dollars, the
conversion rates may be artificial in relation to the actual market values and
may be adverse to Portfolio shareholders.
 
Currency Exchange Rates
 
     A Portfolio's share value may change significantly when the currencies,
other than the U.S. dollar, in which the Portfolio's investments are denominated
strengthen or weaken against the U.S. dollar. Currency
 
                                       41
<PAGE>   48
 
exchange rates generally are determined by the forces of supply and demand in
the foreign exchange markets and the relative merits of investments in different
countries as seen from an international perspective. Currency exchange rates can
also be affected unpredictably by intervention by U.S. or foreign governments or
central banks or by currency controls or political developments in the United
States or abroad.
 
Medium and Lower Rated and Unrated Securities
 
     Securities rated in the fourth highest category by S&P or Moody's, BBB and
Baa, respectively, although considered investment grade, possess speculative
characteristics, and changes in economic or other conditions are more likely to
impair the ability of issuers of these securities to make interest and principal
payments than is the case with respect to issuers of higher grade bonds.
 
     Generally, medium or lower rated securities and unrated securities of
comparable quality, sometimes referred to as "junk bonds," offer a higher
current yield than is offered by higher rated securities, but also (i) will
likely have some quality and protective characteristics that, in the judgment of
the rating organizations, are outweighed by large uncertainties or major risk
exposures to adverse conditions and (ii) are predominantly speculative with
respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. The yield of junk bonds will
fluctuate over time.
 
     The market values of certain of these securities also tend to be more
sensitive to individual corporate developments and changes in economic
conditions than higher quality bonds. In addition, medium and lower rated
securities and comparable unrated securities generally present a higher degree
of credit risk. The risk of loss due to default by these issuers is
significantly greater because medium and lower rated securities and unrated
securities of comparable quality generally are unsecured and frequently are
subordinated to the prior payment of senior indebtedness. Since the risk of
default is higher for lower-rated securities, the Portfolio Advisor's research
and credit analysis are an especially important part of managing securities of
the type held by a Portfolio. In light of these risks, the Board of Trustees has
instructed the Portfolio Advisor, in evaluating the creditworthiness of an
issue, whether rated or unrated, to take various factors into consideration,
which may include, as applicable, the issuer's financial resources, its
sensitivity to economic conditions and trends, the operating history of and the
community support for the facility financed by the issue, the ability of the
issuer's management and regulatory matters.
 
     In addition, the market value of securities in lower rated categories is
more volatile than that of higher quality securities, and the markets in which
medium and lower rated or unrated securities are traded are more limited than
those in which higher rated securities are traded. The existence of limited
markets may make it more difficult for the Portfolios to obtain accurate market
quotations for purposes of valuing their respective portfolios and calculating
their respective net asset values. Moreover, the lack of a liquid trading market
may restrict the availability of securities for the Portfolios to purchase and
may also have the effect of limiting the ability of a Portfolio to sell
securities at their fair value either to meet redemption requests or to respond
to changes in the economy or the financial markets.
 
     Lower rated debt obligations also present risks based on payment
expectations. If an issuer calls the obligation for redemption, a Portfolio may
have to replace the security with a lower yielding security, resulting in a
decreased return for shareholders. Also, as the principal value of bonds moves
conversely with movements in interest rates, in the event of rising interest
rates the value of the securities held by a Portfolio may decline relatively
proportionately more than a portfolio consisting of higher rated securities. If
a Portfolio experiences unexpected net redemptions, it may be forced to sell its
higher rated bonds, resulting in a decline in the overall credit quality of the
securities held by the Portfolio and increasing the exposure of the Portfolio to
the risks of lower rated securities. Investments in zero coupon bonds may be
more speculative and subject to greater fluctuations in value due to changes in
interest rates than bonds that pay interest currently.
 
     Subsequent to its purchase by a Portfolio, an issue of securities may cease
to be rated or its rating may be reduced below the minimum required for purchase
by the Portfolio. Neither event will require sale of these securities by the
Portfolio, but the Portfolio Advisor will consider this event in its
determination of whether the Portfolio should continue to hold the securities.

ADRs, EDRs and CDRs
 
     American Depositary Receipts ("ADRs") are U.S. dollar-denominated receipts
typically issued by domestic banks or trust companies that represent the deposit
with those entities of securities of a foreign issuer. ADRs are publicly traded
on exchanges or over-the-counter in the United States. European Depositary
Receipts ("EDRs"), which are sometimes referred to as Continental Depositary
Receipts ("CDRs"), may also be purchased by the Portfolios. EDRs and CDRs are
generally issued by foreign banks and evidence ownership of either foreign or
domestic securities. Certain institutions issuing ADRs or EDRs may not be
sponsored by the issuer of the underlying foreign securities. A non-sponsored
depository may not provide the same shareholder information that a sponsored
depository is required to provide under its contractual arrangements with the
issuer of the underlying foreign securities.
 
Fixed-Income and Other Debt Instrument Securities
 
     Fixed-income and other debt instrument securities include all bonds, high
yield or "junk" bonds, municipal bonds, debentures, U.S. Government securities,
mortgage-related securities including government stripped mortgage-related
securities, zero coupon securities and custodial receipts. The market value of
fixed-income obligations of the Portfolios will be affected by general changes
in interest rates which will result in increases or decreases in the value of
the obligations held by the Portfolios. The market value of the obligations held
by a Portfolio can be expected to vary inversely to changes in prevailing
interest rates. Shareholders also should recognize that, in periods of declining
interest rates, a Portfolio's yield will tend to be somewhat higher than
prevailing market rates and, in periods of rising interest rates, a Portfolio's
yield will tend to be somewhat lower. Also, when interest rates are falling, the
inflow of net new money to a Portfolio from the continuous sale of its shares
will tend to be invested in instruments producing lower yields than the balance
of its portfolio, thereby reducing the Portfolio's current yield. In periods of
rising interest rates, the opposite can be expected to occur. In addition,
securities in which a Portfolio may invest may not yield as high a level of
current income as might be achieved by investing in securities with less
liquidity, less creditworthiness or longer maturities.
 
     Ratings made available by S&P and Moody's are relative and subjective and
are not absolute standards of quality. Although these ratings are initial
criteria for selection of portfolio investments, a Portfolio Advisor also will
make its own evaluation of these securities. Among the factors that will be
considered are the long-term ability of the issuers to pay principal and
interest and general economic trends.
 
     Fixed-income securities may be purchased on a when-issued or
delayed-delivery basis. See "When-Issued and Delayed-Delivery Securities."
 
U.S. Government Securities
 
     Each Portfolio may invest in U.S. Government securities, which are
obligations issued or guaranteed by the U.S. Government, its agencies,
authorities or instrumentalities. Some U.S. government securities, such as U.S.
Treasury bills, Treasury notes and Treasury 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. Others are supported by: (i) the right of
the issuer to borrow from the U.S. Treasury, such as securities of the Federal
Home Loan Banks; (ii) the discretionary authority of the U.S. government to
purchase the agency's obligations, such as securities of the FNMA; or (iii) only
the credit of the issuer, such as securities of the Student Loan Marketing
Association. No assurance can be given that the U.S. Government will provide
financial support in the future to U.S. government agencies, authorities or
instrumentalities that are not supported by the full faith and credit of the
United States.
 
     Securities guaranteed as to principal and interest by the U.S. government,
its agencies, authorities or instrumentalities include: (i) securities for which
the payment of principal and interest is backed by an irrevocable letter of
credit issued by the U.S. Government or any of its agencies, authorities or
instrumentalities; and (ii) participation interests in loans made to foreign
governments or other entities that are so guaranteed. The secondary market for
certain of these participation interests is limited and, therefore, may be
regarded as illiquid.

Mortgage Related Securities
 
     Each Portfolio may invest in mortgage related securities. There are several
risks associated with mortgage related securities generally. One is that the
monthly cash inflow from the underlying loans may not be sufficient to meet the
monthly payment requirements of the mortgage related security.
 
     Prepayment of principal by mortgagors or mortgage foreclosures will shorten
the term of the underlying mortgage pool for a mortgage related security. Early
returns of principal will affect the average life of the mortgage related
securities remaining in a Portfolio. The occurrence of mortgage prepayments is
affected by factors including the level of interest rates, general economic
conditions, the location and age of the mortgage and other social and
demographic conditions. In periods of rising interest rates, the rate of
prepayment tends to decrease, thereby lengthening the average life of a pool of
mortgage related securities. Conversely, in periods of falling interest rates
the rate of prepayment tends to increase, thereby shortening the average life of
a pool. Reinvestment of prepayments may occur at higher or lower interest rates
than the original investment, thus affecting the yield of a Portfolio. Because
prepayments of principal generally occur when interest rates are declining, it
is likely that a Portfolio will have to reinvest the proceeds of prepayments at
lower interest rates than those at which the assets were previously invested. If
this occurs, a Portfolio's yield will correspondingly decline. Thus, mortgage
related securities may have less potential for capital appreciation in periods
of falling interest rates than other fixed-income securities of comparable
maturity, although these securities may have a comparable risk of decline in
market value in periods of rising interest rates. To the extent that a Portfolio
purchases mortgage related securities at a premium, unscheduled prepayments,
which are made at par, will result in a loss equal to any unamortized premium.
 
     CMOs are obligations fully collateralized by a portfolio of mortgages or
mortgage related securities. Payments of principal and interest on the mortgages
are passed through to the holders of the CMOs on the same schedule as they are
received, although certain classes of CMOs have priority over others with
respect to the receipt of prepayments on the mortgages. Therefore, depending on
the type of CMOs in which a Portfolio invests, the investment may be subject to
a greater or lesser risk of prepayment than other types of mortgage related
securities.
 
     Mortgage related securities may not be readily marketable. To the extent
any of these securities are not readily marketable in the judgment of the
Portfolio Advisor, the investment restriction limiting a Portfolio's investment
in illiquid instruments to not more than 15% of the value of its net assets will
apply.
 
Stripped Mortgage Related Securities
 
     These securities are either issued and guaranteed, or privately-issued but
collateralized by securities issued, by GNMA, FNMA or FHLMC. These securities
represent beneficial ownership interests in either periodic principal
distributions ("principal-only") or interest distributions ("interest-only") on
mortgage related certificates issued by GNMA, FNMA or FHLMC, as the case may be.
The certificates underlying the stripped mortgage related securities represent
all or part of the beneficial interest in pools of mortgage loans. The Portfolio
will invest in stripped mortgage related securities in order to enhance yield or
to benefit from anticipated appreciation in value of the securities at times
when its Portfolio Advisor believes that interest rates will remain stable or
increase. In periods of rising interest rates, the expected increase in the
value of stripped mortgage related securities may offset all or a portion of any
decline in value of the securities held by the Portfolio.
 
     Investing in stripped mortgage related securities involves the risks
normally associated with investing in mortgage related securities. See "Mortgage
Related Securities" above. In addition, the yields on stripped mortgage related
securities are extremely sensitive to the prepayment experience on the mortgage
loans underlying the certificates collateralizing the securities. If a decline
in the level of prevailing interest rates results in a rate of principal
prepayments higher than anticipated, distributions of principal will be
accelerated, thereby reducing the yield to maturity on interest-only stripped
mortgage related securities and increasing the yield to maturity on
principal-only stripped mortgage related securities. Sufficiently high
prepayment rates could result in a Portfolio not fully recovering its initial
investment in an interest-only stripped mortgage related security. Under current
market conditions, the Portfolio expects that investments in stripped mortgage
related securities
 
                                       44
<PAGE>   51
 
will consist primarily of interest-only securities. Stripped mortgage related
securities are currently traded in an over-the-counter market maintained by
several large investment banking firms. There can be no assurance that the
Portfolio will be able to effect a trade of a stripped mortgage related security
at a time when it wishes to do so. The Portfolio will acquire stripped mortgage
related securities only if a secondary market for the securities exists at the
time of acquisition. Except for stripped mortgage related securities based on
fixed rate FNMA and FHLMC mortgage certificates that meet certain liquidity
criteria established by the Board of Trustees, the Portfolios will treat
stripped mortgage related securities as illiquid and will limit its investments
in these securities, together with other illiquid investments, to not more than
15% of net assets.
 
Zero Coupon Securities
 
     Zero coupon U.S. Government securities are debt obligations that are issued
or purchased at a significant discount from face value. The discount
approximates the total amount of interest the security will accrue and compound
over the period until maturity or the particular interest payment date at a rate
of interest reflecting the market rate of the security at the time of issuance.
Zero coupon securities do not require the periodic payment of interest. These
investments benefit the issuer by mitigating its need for cash to meet debt
service, but also require a higher rate of return to attract investors who are
willing to defer receipt of cash. These investments may experience greater
volatility in market value than U.S. Government securities that make regular
payments of interest. A Portfolio accrues income on these investments for tax
and accounting purposes, which is distributable to shareholders and which,
because no cash is received at the time of accrual, may require the liquidation
of other portfolio securities to satisfy the Portfolio's distribution
obligations, in which case the Portfolio will forego the purchase of additional
income producing assets with these funds. Zero coupon securities include STRIPS,
that is, securities underwritten by securities dealers or banks that evidence
ownership of future interest payments, principal payments or both on certain
notes or bonds issued by the U.S. Government, its agencies, authorities or
instrumentalities. They also include Coupons Under Book Entry System ("CUBES"),
which are component parts of U.S. Treasury bonds and represent scheduled
interest and principal payments on the bonds.
 
Custodial Receipts
 
     Custodial receipts or certificates, such as Certificates of Accrual on
Treasury Securities ("CATS"), Treasury Investors Growth Receipts ("TIGRs") and
Financial Corporation certificates ("FICO Strips"), are securities underwritten
by securities dealers or banks that evidence ownership of future interest
payments, principal payments or both on certain notes or bonds issued by the
U.S. Government, its agencies, authorities or instrumentalities. The
underwriters of these certificates or receipts purchase a U.S. Government
security and deposit the security in an irrevocable trust or custodial account
with a custodian bank, which then issues receipts or certificates that evidence
ownership of the periodic unmatured coupon payments and the final principal
payment on the U.S. Government Security. Custodial receipts evidencing specific
coupon or principal payments have the same general attributes as zero coupon
U.S. Government securities, described above. Although typically under the terms
of a custodial receipt a Portfolio is authorized to assert its rights directly
against the issuer of the underlying obligation, the Portfolio may be required
to assert through the custodian bank such rights as may exist against the
underlying issuer. Thus, if the underlying issuer fails to pay principal and/or
interest when due, a Portfolio may be subject to delays, expenses and risks that
are greater than those that would have been involved if the Portfolio had
purchased a direct obligation of the issuer. In addition, if the trust or
custodial account in which the underlying security has been deposited is
determined to be an association taxable as a corporation, instead of a
non-taxable entity, the yield on the underlying security would be reduced in
respect of any taxes paid.
 
When-Issued and Delayed-Delivery Securities
 
     To secure prices deemed advantageous at a particular time, each Portfolio
may purchase securities on a when-issued or delayed-delivery basis, in which
case delivery of the securities occurs beyond the normal settlement period;
payment for or delivery of the securities would be made prior to the reciprocal
delivery or payment by the other party to the transaction. A Portfolio will
enter into when-issued or delayed-delivery
 
                                       45
<PAGE>   52
 
transactions for the purpose of acquiring securities and not for the purpose of
leverage. When-issued securities purchased by the Portfolio may include
securities purchased on a "when, as and if issued" basis under which the
issuance of the securities depends on the occurrence of a subsequent event, such
as approval of a merger, corporate reorganization or debt restructuring.
 
     Securities purchased on a when-issued or delayed-delivery basis may expose
a Portfolio to risk because the securities may experience fluctuations in value
prior to their actual delivery. The Portfolio does not accrue income with
respect to a when-issued or delayed-delivery security prior to its stated
delivery date. Purchasing securities on a when-issued or delayed-delivery basis
can involve the additional risk that the yield available in the market when the
delivery takes place may be higher than that obtained in the transaction itself.
 
Repurchase Agreements
 
     Each of the Portfolios may engage in repurchase agreement transactions.
Under the terms of a typical repurchase agreement, a Portfolio would acquire an
underlying debt obligation for a relatively short period (usually not more than
one week) subject to an obligation of the seller to repurchase, and the
Portfolio to resell, the obligation at an agreed-upon price and time, thereby
determining the yield during the Portfolio's holding period. This arrangement
results in a fixed rate of return that is not subject to market fluctuations
during the Portfolio's holding period. A Portfolio may enter into repurchase
agreements with respect to U.S. government securities with member banks of the
Federal Reserve System and certain non-bank dealers approved by the respective
Board of Trustees. Under each repurchase agreement, the selling institution is
required to maintain the value of the securities subject to the repurchase
agreement at not less than their repurchase price. The Portfolio Advisor, acting
under the supervision of the Advisor and the Board of Trustees, reviews on an
ongoing basis the value of the collateral and the creditworthiness of those
non-bank dealers with whom the Portfolio enters into repurchase agreements. In
entering into a repurchase agreement, a Portfolio bears a risk of loss in the
event that the other party to the transaction defaults on its obligations and
the Portfolio is delayed or prevented from exercising its rights to dispose of
the underlying securities, including the risk of a possible decline in the value
of the underlying securities during the period in which the Portfolio seeks to
assert its rights to them, the risk of incurring expenses associated with
asserting those rights and the risk of losing all or a part of the income from
the agreement. Repurchase agreements are considered to be collateralized loans
under the 1940 Act.
 
Reverse Repurchase Agreements and Forward Roll Transactions
 
     The Portfolios may enter into reverse repurchase agreements and forward
roll transactions. In a reverse repurchase agreement the Portfolio agrees to
sell portfolio securities to financial institutions such as banks and
broker-dealers and to repurchase them at a mutually agreed date and price.
Forward roll transactions are equivalent to reverse repurchase agreements but
involve mortgage-backed securities and involve a repurchase of a substantially
similar security. At the time the Portfolio enters into a reverse repurchase
agreement or forward roll transaction it will place in a segregated custodial
account cash or liquid securities having a value equal to the repurchase price,
including accrued interest. Reverse repurchase agreements and forward roll
transactions involve the risk that the market value of the securities sold by
the Portfolio may decline below the repurchase price of the securities. Reverse
repurchase agreements and forward roll transactions are considered to be
borrowings by a Portfolio for purposes of the limitations described in "Certain
Investment Restrictions" below and in the Statement of Additional Information.
 
Lending Portfolio Securities
 
     To generate income for the purpose of helping to meet its operating
expenses, each Portfolio may lend securities to brokers, dealers and other
financial organizations. These loans, if and when made, may not exceed 30% of a
Portfolio's assets taken at value. A Portfolio's loans of securities will be
collateralized by cash, letters of credit or U.S. Government securities. The
cash or instruments collateralizing a Portfolio's loans of securities will be
maintained at all times in a segregated account with the Portfolio's custodian,
or with a designated subcustodian, in an amount at least equal to the current
market value of the loaned securities. In lending securities to brokers, dealers
and other financial organizations, a Portfolio is subject to risks, which, like
those associated with other extensions of credit, include delays in recovery and
possible loss of rights in the collateral
 
                                       46
<PAGE>   53
 
should the borrower fail financially. For further information regarding measures
to be taken to protect a lending Portfolio, see the Statement of Additional
Information.
 
Illiquid Securities
 
     No Portfolio may invest more than 15% of its net assets in securities which
are illiquid or otherwise not readily marketable. If a security becomes illiquid
after purchase by the Portfolio, the Portfolio will normally sell the security
unless to do so would not be in the best interests of shareholders.
 
Non-Publicly Traded ("Restricted") Securities and Rule 144A Securities
 
     Each Portfolio may purchase securities in the United States that are not
registered for sale under federal securities laws but which can be resold to
institutions under SEC Rule 144A or under an exemption from such laws. If a
dealer or institutional trading market in such securities exists, these
restricted securities or Rule 144A securities are treated as exempt from the
Portfolio's 15% limit on illiquid securities. The Board of Trustees of the SA
Trust, with advice and information from the respective Portfolio Advisor, will
determine the liquidity of restricted securities or Rule 144A securities by
looking at factors such as trading activity and the availability of reliable
price information and, through reports from such Portfolio Advisor, the Board of
Trustees of the Portfolio Trust will monitor trading activity in restricted
securities. If institutional trading in restricted securities or Rule 144A
securities were to decline, a Portfolio's illiquidity could be increased and the
Portfolio could be adversely affected.
 
     No Portfolio will invest more than 10% of its total assets in restricted
securities (excluding Rule 144A securities).
 
Temporary Investments
 
     For temporary defensive purposes during periods when the Portfolio Advisor
of a Portfolio believes, in consultation with the Advisor, that pursuing the
Portfolio's basic investment strategy may be inconsistent with the best
interests of its shareholders, the Portfolio may invest its assets without limit
in the following money market instruments: U.S. Government securities (including
those purchased in the form of custodial receipts), repurchase agreements,
certificates of deposit and bankers' acceptances issued by banks or savings and
loan associations having assets of at least $500 million as of the end of their
most recent fiscal year and high quality commercial paper. In addition, for the
same purposes the Portfolio Advisor may invest without limit in obligations
issued or guaranteed by foreign governments or by any of their political
subdivisions, authorities, agencies or instrumentalities that are rated at least
AA by S&P or Aa by Moody's or, if unrated, are determined by the Portfolio
Advisor to be of equivalent quality. Each Portfolio also may hold a portion of
its assets in money market instruments or cash in amounts designed to pay
expenses, to meet anticipated redemptions or pending investments in accordance
with its objectives and policies. Any temporary investments may be purchased on
a when-issued basis.
 
Futures Contracts and Related Options
 
     Each Portfolio may enter into futures contracts and purchase and write
(sell) options on these contracts, including but not limited to interest rate,
securities index and foreign currency futures contracts and put and call options
on these futures contracts. These contracts will be entered into only upon the
concurrence of the Portfolio Advisor that such contracts are necessary or
appropriate in the management of the Portfolio's assets. These contracts will be
entered into on exchanges designated by the Commodity Futures Trading Commission
("CFTC") or, consistent with CFTC regulations, on foreign exchanges. These
transactions may be entered into for bona fide hedging and other permissible
risk management purposes including protecting against anticipated changes in the
value of securities a Portfolio intends to purchase.
 
     No Portfolio will hedge more than 25% of its total assets by selling
futures, buying puts, and writing calls under normal conditions. In addition, no
Portfolio will buy futures or write puts whose underlying value exceeds 25% of
its total assets, and no Portfolio will buy calls with a value exceeding 5% of
its total assets.
 
                                       47
<PAGE>   54
 
     A Portfolio will not enter into futures contracts and related options for
which the aggregate initial margin and premiums exceed 5% of the fair market
value of the Portfolio's assets after taking into account unrealized profits and
unrealized losses on any contracts it has entered into.
 
     A Portfolio may lose the expected benefit of these futures or options
transactions and may incur losses if the prices of the underlying commodities
move in an unanticipated manner. In addition, changes in the value of the
Portfolio's futures and options positions may not prove to be perfectly or even
highly correlated with changes in the value of its portfolio securities.
Successful use of futures and related options is subject to a Portfolio
Advisor's ability to predict correctly movements in the direction of the
securities markets generally, which ability may require different skills and
techniques than predicting changes in the prices of individual securities.
Moreover, futures and options contracts may only be closed out by entering into
offsetting transactions on the exchange where the position was entered into (or
a linked exchange), and as a result of daily price fluctuation limits there can
be no assurance that an offsetting transaction could be entered into at an
advantageous price at any particular time. Consequently, a Portfolio may realize
a loss on a futures contract or option that is not offset by an increase in the
value of its portfolio securities that are being hedged or a Portfolio may not
be able to close a futures or options position without incurring a loss in the
event of adverse price movements. For additional information, see "Futures
Contracts and Options on Futures Contracts" in the Statement of Additional
Information.
 
Options on Stock
 
     Each Portfolio may write and purchase options on stocks. A call option
gives the purchaser of the option the right to buy, and obligates the writer to
sell, the underlying stock at the exercise price at any time during the option
period. Similarly, a put option gives the purchaser of the option the right to
sell, and obligates the writer to buy the underlying stock at the exercise price
at any time during the option period. A covered call option with respect to
which a Portfolio owns the underlying stock sold by the Portfolio exposes the
Portfolio during the term of the option to possible loss of opportunity to
realize appreciation in the market price of the underlying stock or to possible
continued holding of a stock which might otherwise have been sold to protect
against depreciation in the market price of the stock. A covered put option sold
by a Portfolio exposes the Portfolio during the term of the option to a decline
in price of the underlying stock.
 
     To close out a position when writing covered options, a Portfolio may make
a "closing purchase transaction" which involves purchasing an option on the same
stock with the same exercise price and expiration date as the option which it
has previously written on the stock. The Portfolio will realize a profit or loss
for a closing purchase transaction if the amount paid to purchase an option is
less or more, as the case may be, than the amount received from the sale
thereof. To close out a position as a purchaser of an option, a Portfolio may
make a "closing sale transaction" which involves liquidating the Portfolio's
position by selling the option previously purchased. See also "Options on
Securities" in the Statement of Additional Information.
 
Options on Securities Indexes
 
     Each Portfolio may purchase and write put and call options on securities
indexes listed on domestic and, in the case of those Portfolios which may invest
in foreign securities, on foreign exchanges. A securities index fluctuates with
changes in the market values of the securities included in the index.
 
     Options on securities indexes are generally similar to options on stock
except that the delivery requirements are different. Instead of giving the right
to take or make delivery of stock at a specified price, an option on a security
index gives the holders the right to receive a cash "exercise settlement amount"
equal to (a) the amount, if any, by which the fixed exercise price of the option
exceeds (in the case of a put) or is less than (in the case of a call) the
closing value of the underlying index on the date of the exercise, multiplied by
(b) a fixed "index multiplier." Receipt of this cash amount will depend upon the
closing level of the index upon which the option is based being greater than, in
the case of a call, or less than, in the case of a put, the exercise price of
the option. The amount of cash received will be equal to such difference between
the closing price of the index and the exercise price of the option expressed in
dollars or a foreign currency, as the case may be, times a specified multiple.
The writer of the option is obligated, in return for the premium received, to
make delivery of this
 
                                       48
<PAGE>   55
 
amount. The writer may offset its position in securities index options prior to
expiration by entering into a closing transaction on an exchange or the option
may expire unexercised.
 
     Because the value of an index option depends upon movements in the level of
the index rather than the price of a particular security, whether the Portfolio
will realize a gain or loss from the purchase or writing of options on an index
depends upon movements in the level of securities prices in the market generally
or, in the case of certain indexes, in an industry or market segment, rather
than movements in price of a particular security. Accordingly, successful use by
a Portfolio of options on security indexes will be subject to the Portfolio
Advisor's ability to predict correctly movement in the direction of that
securities market generally or of a particular industry. This requires different
skills and techniques than predicting changes in the price of individual
securities. For further information regarding index options, see "Options on
Securities Indexes" in the Statement of Additional Information.
 
Forward Currency Contracts
 
     Each Portfolio may hold currencies to meet settlement requirements for
foreign securities and may engage in currency exchange transactions in order to
protect against uncertainty in the level of future exchange rates between a
particular foreign currency and the U.S. dollar or between foreign currencies in
which the Portfolio's securities are or may be denominated. Forward currency
contracts are agreements to exchange one currency for another, for example, to
exchange a certain amount of U.S. dollars for a certain amount of French francs
at a future date. The date (which may be any agreed-upon fixed number of days in
the future), the amount of currency to be exchanged and the price at which the
exchange will take place will be negotiated with a currency trader and fixed for
the term of the contract at the time that the Portfolio enters into the
contract.
 
     In hedging specific portfolio positions, a Portfolio may enter into a
forward contract with respect to either the currency in which the positions are
denominated or another currency deemed appropriate by the Portfolio Advisor. The
amount the Portfolio may invest in forward currency contracts is limited to the
amount of the Portfolio's aggregate investments in foreign currencies. Risks
associated with entering into forward currency contracts include the possibility
that the market for forward currency contracts may be limited with respect to
certain currencies and, upon a contract's maturity, the inability of a Portfolio
to negotiate with the dealer to enter into an offsetting transaction. Forward
currency contracts may be closed out only by the parties entering into an
offsetting contract. In addition, the correlation between movements in the
prices of those contracts and movements in the price of the currency hedged or
used for cover will not be perfect. There is no assurance that an active forward
currency contract market will always exist. These factors will restrict a
Portfolio's ability to hedge against the risk of devaluation of currencies in
which a Portfolio holds a substantial quantity of securities and are unrelated
to the qualitative rating that may be assigned to any particular security. See
also "Forward Currency Contracts" in the Statement of Additional Information for
further information concerning forward currency contracts.
 
Real Estate Investment Trusts
 
     The Growth & Income Portfolio may invest in REITs, which can generally be
classified as equity REITs, mortgage REITs and hybrid REITs. Equity REITs, which
invest the majority of their assets directly in real property, derive their
income primarily from rents. Equity REITs can also realize capital gains by
selling properties that have appreciated in value. Mortgage REITs, which invest
the majority of their assets in real estate mortgages, derive their income
primarily from interest payments on real estate mortgages in which they are
invested. Hybrid REITs combine the characteristics of both equity REITs and
mortgage REITs.
 
     Investment in REITs is subject to risks similar to those associated with
the direct ownership of real estate (in addition to securities markets risks).
REITs are sensitive to factors such as changes in real estate values and
property taxes, interest rates, cash flow of underlying real estate assets,
supply and demand, and the management skill and creditworthiness of the issuer.
REITs may also be affected by tax and regulatory requirements.
 
                                       49
<PAGE>   56
 
Standard & Poor's Depositary Receipts ("SPDRs")
 
     The Growth & Income Portfolio may invest in SPDRs. SPDRs typically trade
like a share of common stock and provide investment results that generally
correspond to the price and yield performance of the component common stocks of
the S&P 500 Index. There can be no assurance that this can be accomplished as it
may not be possible for the Portfolio to replicate and maintain exactly the
composition and relative weightings of the S&P 500 Index securities. SPDRs are
subject to the risks of an investment in a broadly based portfolio of common
stocks, including the risk that the general level of stock prices may decline,
thereby adversely affecting the value of such investment.
 
ASSET COVERAGE
 
     To assure that a Portfolio's use of futures and related options, as well as
when-issued and delayed-delivery transactions, forward currency contracts and
swap transactions, are not used to achieve investment leverage, the Portfolio
will cover such transactions, as required under applicable SEC interpretations,
either by owning the underlying securities or by establishing a segregated
account with the SA Trust's custodian containing liquid securities in an amount
at all times equal to or exceeding the Portfolio's commitment with respect to
these instruments or contracts.
 
CERTAIN INVESTMENT RESTRICTIONS
 
     The SA Trust, on behalf of each SAT Portfolio, has adopted certain
investment restrictions that are enumerated in detail in the Statement of
Additional Information. Among other restrictions, each SAT Portfolio may not,
with respect to 75% of its total assets taken at market value, invest more than
5% of its total assets in the securities of any one issuer, except U.S.
Government securities, or acquire more than 10% of any class of the outstanding
voting securities of any one issuer. In addition, no Portfolio may invest more
than 25% of its total assets in securities of issuers in any one industry. Each
Portfolio may borrow money as a temporary measure from banks in an aggregate
amount not exceeding one-third of the value of the Portfolio's total assets to
meet redemptions and for other temporary or emergency purposes not involving
leveraging. Reverse repurchase agreements and forward roll transactions
involving mortgage-related securities will be aggregated with bank borrowings
for purposes of this calculation. No Portfolio may purchase securities while
borrowings exceed 5% of the value of the Portfolio's total assets. No Portfolio
will invest more than 15% of the value of its net assets in securities that are
illiquid, including certain government stripped mortgage related securities,
repurchase agreements maturing in more than seven days and that cannot be
liquidated prior to maturity and securities that are illiquid by virtue of the
absence of a readily available market. Securities that have legal or contractual
restrictions on resale but have a readily available market, such as certain Rule
144A securities, are deemed not illiquid for this purpose. No Portfolio may
invest more than 10% of its assets in restricted securities (excluding Rule 144A
securities). See "Illiquid Securities" and "Non-Publicly Traded ("Restricted")
Securities and Rule 144A Securities."
 
PORTFOLIO TURNOVER
 
     Generally, the SAT Portfolios will not trade in securities for short-term
profits but, when circumstances warrant, securities may be sold without regard
to the length of time held. The SAT Portfolios may engage in active short-term
trading to benefit from yield disparities among different issues of securities,
to seek short-term profits during periods of fluctuating interest rates or for
other reasons. Active trading will increase a Portfolio's rate of turnover,
certain transaction expenses and the incidence of short-term capital gain
taxable as ordinary income. An annual turnover rate of 100% would occur when all
the securities held by the Portfolio are replaced one time during a period of
one year. The turnover rates of the Growth & Income Portfolio and the Bond
Portfolio for 1996 and 1995 were 82% and 96% and 79% and 80%, respectively.

                           MANAGEMENT OF THE SA TRUST
BOARD OF TRUSTEES
 
     Overall responsibility for management and supervision of the SA Trust rests
with its Board of Trustees. The Trustees approve all significant agreements
between the SA Trust and the persons and companies that furnish services to the
SA Trust and the Portfolios, including agreements between the SA Trust and each
of the Custodian, the Advisor and the Administrator. Due to the services
provided by the Advisor and the Administrator, the Trust currently has no
employees and its officers are not required to devote their full time to the
affairs of the SA Trust. The Statement of Additional Information contains
background information regarding each Trustee and executive officer of the SA
Trust.
 
ADMINISTRATOR, FUND ACCOUNTING AGENT, CUSTODIAN AND TRANSFER AGENT
 
     Investors Bank, 200 Clarendon Street, Boston, Massachusetts 02116, serves
as administrator, fund accounting agent, custodian and transfer agent for the SA
Trust. Investors Bank was organized in 1969 as a Massachusetts-chartered trust
company and is a wholly-owned subsidiary of Investors Financial Services Corp.,
a publicly-held corporation and holding company registered under the Bank
Holding Company Act of 1956.
 
     As administrator and fund accounting agent, Investors Bank provides, on
behalf of the SA Trust, accounting, clerical and bookkeeping services; the daily
calculation of net asset values; state securities registration services;
corporate secretarial services; assistance in the preparation of management
reports; preparation and filing of tax returns, registration statements, and
reports to shareholders and to the SEC. Investors Bank also provides personnel
to serve as certain officers of the SA Trust.
 
     As custodian, Investors Bank holds cash, securities and other assets of the
SA Trust as required by the 1940 Act. As transfer agent, Investors Bank is
responsible for maintaining records of shareholder interests for the SA Trust.
 
     For its services as fund accounting agent and administrator, each SAT
Portfolio shall pay fees to Investors Bank that are computed and paid monthly.
Such fees equal, in the aggregate, 0.12% on an annual basis of the average daily
net assets of all the portfolios and funds for which Investors Bank acts as fund
accounting agent and administrator up to $1 billion in assets and 0.08% on an
annual basis of average daily net assets which exceed $1 billion, subject to
certain annual minimum fees. As compensation for its services as custodian to
the SA Trust, Investors Bank receives fees, computed and paid monthly, that
aggregate 0.03% on an annual basis of the average daily net assets of all the
portfolios and funds for which Investors Bank acts as custodian up to $500
million and 0.02% on an annual basis of such average daily net assets for the
next $500 million and 0.01% on an annual basis of such average daily net assets
which exceed $1 billion.
 
SPONSOR
 
     Touchstone Advisors, Inc., as Sponsor to the SA Trust pursuant to a Sponsor
Agreement, provides oversight of the various service providers to the SA Trust,
including the Administrator, Custodian and Transfer Agent. As Sponsor to the SA
Trust, Touchstone Advisors reserves the right to receive a sponsor fee from each
Portfolio equal on an annual basis to 0.20% of the average daily net assets of
that Portfolio for its then current fiscal year. The Sponsor Agreement may be
terminated by the Sponsor as of the end of any calendar quarter after December
31, 1998 on not less than 30 days prior written notice. The SA Trust may
terminate the Sponsor Agreement at any time on not less than 30 days prior
written notice. The Sponsor has advised the SA Trust that it will waive all fees
under the Sponsor Agreement through April 30, 1999.
 
ALLOCATION OF EXPENSES OF THE PORTFOLIOS
 
     Each SAT Portfolio bears its own expenses, which generally include all
costs not specifically borne by the Advisor, the SAT Portfolio Advisors and the
Administrator. Included among a Portfolio's expenses are: costs incurred in
connection with its organization; investment management and administration fees;
sponsor fees; fees for necessary professional and brokerage services; fees for
any pricing service; the costs of regulatory compliance; and costs associated
with maintaining the SA Trust's legal existence and shareholder relations. Under
separate
 
                                       51
<PAGE>   58
 
agreements with the SA Trust, the Sponsor has agreed to reimburse each SAT
Portfolio to the extent that the aggregate operating expenses of the Portfolio
exceed agreed upon expense limitations (the "EXPENSE CAPS"). The Sponsor's
obligation to reimburse the SA Trust for such amounts may be terminated by the
Sponsor at the end of any calendar quarter after December 31, 1998. For more
detailed information regarding the Expense Caps, see "Fee and Expense Tables"
and "Expenses of VIT Portfolios and SAT Portfolios; Expense Caps."
 
                             PURCHASE AND VALUATION
PURCHASE
 
     Interests in the Growth & Income and Bond Portfolios are not offered to the
public and are issued solely in private placement transactions that do not
involve any "public offering" within the meaning of Section 4(2) of the 1933
Act. Investments in the Growth & Income and Bond Portfolios may be made only by
a limited number of insurance company separate accounts. This Prospectus and its
accompanying Statement of Additional Information do not constitute an offer to
sell, or the solicitation of an offer to buy, any "security" (within the meaning
of the 1933 Act) of the Portfolios.
 
VALUATION
 
     The net asset value of each SAT Portfolio is determined as of the close of
regular trading on the NYSE on each day on which the NYSE is open for trading,
by deducting the amount of the Portfolio's liabilities from the value of its
assets. At the close of each such business day, the value of each Sub-Account's
interest in the Portfolio will be determined by multiplying the net asset value
of the corresponding Portfolio by the percentage, effective for that day, that
represents the Sub-Account's share of the aggregate interests in that Portfolio.
 
     Generally, a Portfolio's investments are valued at market value or, in the
absence of a market value, at fair value as determined by or under the direction
of the SA Trust's Board of Trustees.
 
     Securities that are primarily traded on foreign exchanges are generally
valued at the preceding closing values of the securities on their respective
exchanges, except that, when an occurrence subsequent to the time a value was so
established is likely to have changed that value, the fair market value of those
securities will be determined by consideration of other factors by or under the
direction of the Board of Trustees of the SA Trust. A security that is primarily
traded on a domestic or foreign stock exchange is valued at the last sales price
on that exchange or, if no sales occurred during the day, at the current quoted
bid price. All short-term dollar-denominated investments that mature in 60 days
or less are valued on the basis of amortized cost (which involves valuing an
investment at its cost and, thereafter, assuming a constant amortization to
maturity of any discount or premium, regardless of the effect of fluctuating
interest rates on the market value of the investment) when the Board of Trustees
of the SA Trust has determined that amortized cost represents fair value. An
option that is written by a Portfolio is generally valued at the last sale price
or, in the absence of the last sale price, the last offer price. An option that
is purchased by a Portfolio is generally valued at the last sale price or, in
the absence of the last sale price, the last bid price. The value of a futures
contract is equal to the unrealized gain or loss on the contract that is
determined by marking the contract to the current settlement price for a like
contract on the valuation date of the futures contract. A settlement price may
not be used if the market makes the maximum price change in a single trading
session permitted by an exchange (a "limit move") with respect to a particular
futures contract or if the securities underlying the futures contract experience
significant price fluctuations after the determination of the settlement price.
When a settlement price cannot be used, futures contracts will be valued at
their fair market value as determined by or under the direction of the Board of
Trustees of the SA Trust.
 
     All assets and liabilities initially expressed in foreign currency values
will be converted into U.S. dollar values at the mean between the bid and
offered quotations of the currencies against U.S. dollars as last quoted by any
recognized dealer. If the bid and offered quotations are not available, the rate
of exchange will be determined in good faith by the Board of Trustees of the SA
Trust. In carrying out the valuation policies of the Board of Trustees of the SA
Trust, independent pricing services may be consulted. Further information
regarding the SA Trust's valuation policies is contained in the Statement of
Additional Information.

                             ADDITIONAL INFORMATION
 
DESCRIPTION OF BENEFICIAL INTERESTS, VOTING RIGHTS AND LIABILITIES
 
     Each investor in an SAT Portfolio, including the corresponding Sub-Account,
may add to or reduce its investment in the Portfolio on each day the Portfolio
determines its net asset value. At the close of each such business day, the
value of each investor's beneficial interest in the Portfolio will be determined
by multiplying the net asset value of the Portfolio by the percentage, effective
for that day, which represents that investor's share of the aggregate beneficial
interests in the Portfolio. Any additions or withdrawals, which are to be
effected as of the close of business on that day, will then be effected. The
investor's percentage of the aggregate beneficial interests in the Portfolio
will then be re-computed as the percentage equal to the fraction (i) the
numerator of which is the value of such investor's investment in the Portfolio
as of the close of business on such day plus or minus, as the case may be, the
amount of any additions to or withdrawals from the investor's investment in the
Portfolio effected as of the close of business on such day, and (ii) the
denominator of which is the aggregate net asset value of the Portfolio as of the
close of business on such day plus or minus, as the case may be, the amount of
the net additions to or withdrawals from the aggregate investments in the
Portfolio by all investors in the Portfolio. The percentage so determined will
then be applied to determine the value of the investor's interest in the
Portfolio as of the close of business on the following business day.
 
     The SA Trust was organized as a trust under the laws of the State of New
York pursuant to a Declaration of Trust dated February 7, 1994, at which time
the SAT Portfolios were established and designated as a separate series of this
SA Trust. The Declaration of Trust provides that the Sub-Accounts and other
entities investing in the Portfolios (e.g., other insurance company separate
accounts) will each be liable for all obligations of the corresponding
Portfolio. However, the risk of a Sub-Account incurring financial loss on
account of such liability is limited to circumstances in which both inadequate
insurance existed and the corresponding Portfolio itself was unable to meet its
obligations. Accordingly, the Trustees of the SA Trust believe that neither the
Sub-Account nor its Owners having Contract Value therein will for this reason be
adversely affected as a result of the Sub-Account investing in the Portfolios.
The interests in SA Trust are divided into separate series. No series of SA
Trust has any preference over any other series.
 
     Each Sub-Account will be involved only in votes that affect the
corresponding SAT Portfolio. Owners investing in Sub-Accounts that are, in turn,
investing in the SAT Portfolios will, however, vote with other investors in all
of the SA Trust's Portfolios (of which there are seven) to elect Trustees of the
SA Trust and for certain other matters. Under certain circumstances the
investors of one or more series of the SA Trust (including the SAT Portfolios)
could control the outcome of these votes. Holders of interests in each Portfolio
will vote separately on matters affecting only that Portfolio. Under certain
circumstances, other investors in a Portfolio could control the outcome of these
votes.
 
     Separate Account 1 sends to each shareholder a semi-annual report and an
audited annual report. At least one such report in each year will include a list
of the investment securities held by the SAT Portfolios. See "Statements to
Contract Owners."
 
     No person has been authorized to give any information or to make any
representations other than those contained in this Prospectus, the corresponding
Statement of Additional Information, and in the Company's official sales
literature in connection with the offering of interests in the Contracts, and if
given or made, such other information or representations must not be relied upon
as having been authorized by the Company. This Prospectus does not constitute an
offer in any state in which, or to any person to whom, such offer may not
lawfully be made.

PART I - DISCUSSION REGARDING THE VARIABLE ANNUITY CONTRACTS

GENERAL

         Except as otherwise indicated herein, all capitalized terms shall have
the meanings assigned to them in the Prospectus.

         The Company is subject to regulation by the Ohio Department of
Insurance, which periodically examines its financial condition and operations.
The Company also is subject to the insurance laws and regulations of all
jurisdictions in which it offers Contracts. Copies of the Contract have been
filed with, and, where required, approved by insurance regulators in those
jurisdictions. The Company must submit annual statements of its operations,
including financial statements, to such state insurance regulators so that they
may determine solvency and compliance with applicable state insurance laws and
regulations.

         The Company and Separate Account 1 have filed a Registration Statement
regarding the Contracts with the Securities and Exchange Commission under the
Investment Company Act of 1940 and the Securities Act of 1933. The Prospectus
and this Statement of Additional Information do not contain all of the
information in the Registration Statement.

SAFEKEEPING OF ASSETS

         The assets of Separate Account 1 are held by the Company, separate from
the Company's general account assets and any other separate accounts which the
Company has or will establish. The Company maintains records of all purchases
and redemptions of the interests in the Portfolios held by the Sub-Accounts. The
Company maintains fidelity bond coverage for the acts of its officers and
employees.

DISTRIBUTION OF THE CONTRACTS

         As disclosed in the Prospectus, the Contracts are distributed through
Touchstone Securities, Inc. (the "DISTRIBUTOR"), which is a wholly-owned
subsidiary of IFS Financial Services, Inc. ("IFS"). IFS is a wholly-owned
subsidiary of the Company. The Distributor is a member of the National
Association of Securities Dealers, Inc. The offering of the Contracts is
continuous, and the Company does not anticipate discontinuing offering the
Contracts, although it reserves the right to do so. Sales commissions
attributable to Separate Account 1 paid by the Company to the Distributor for
the period from February 23, 1995 to December 31, 1995, and for the year ended
December 31, 1996, totalled $159,807 and $1,902,186, respectively, and $26,967
and $305,688 of those amounts, respectively, were retained by the Distributor.

SUB-ACCOUNT PERFORMANCE

         The performance of the Sub-Accounts may be quoted or advertised by the
Company in various ways. All performance information supplied by the Company in
advertising is based upon historical results of the Sub-Accounts and the
Portfolios and is not intended to indicate future performance of either one.
Total returns and other performance information may be 



                                       3
<PAGE>   65



quoted numerically or in a table, graph or similar illustration. The value of an
Accumulation Unit and total returns fluctuate in response to market conditions,
interest rates and other factors.

        Average annual total returns are calculated by determining the average
annual compounded rates of return over one, five and ten year periods (or since
commencement of operations) that would equate an initial hypothetical investment
to the ending redeemable value according to the following formula:

                         P (1 + T)n = ERV
        where:

                   P = a hypothetical initial Purchase Payment of $1,000 
                   T = average annual total return 
                   n = number of years and/or portion of a year
                 ERV = ending redeemable value of a hypothetical  
                       initial Purchase Payment of $1,000 at the end of the 
                       applicable period

     While average annual total returns are convenient means of comparing
investment alternatives, investors should realize that any Sub-Account's
performance is not constant over time, but changes from year to year, and that
average annual total returns represent averaged figures as opposed to the actual
year-to-year performance of any Sub-Account.

     Average annual total return is calculated as required by applicable
regulations. In addition to average annual total returns, a Sub-Account may
quote cumulative total returns reflecting the simple change in value of any
investment over a stated period. Average annual and cumulative total returns may
be quoted as a percentage or as a dollar amount.

     "Total return" or "average annual total return" quoted in advertising
reflects all aspects of a Sub-Account's return, including the effect of
reinvestment by the Variable Account of Portfolio income and capital gain
distributions and any change in the Sub-Account's value over the applicable
period. Such quotations reflect Contract Maintenance, Contract Administration
and Mortality and Expense Risk Charges. Since the Contract is intended as a
long-term investment, total return calculations will assume that no partial
withdrawals from the hypothetical Contract occurred during the applicable
period, but that a Surrender Charge would be incurred upon the hypothetical
withdrawal at the end of the applicable period.

     Any total return quotation provided for a Sub-Account should not be
considered as representative of the performance of the Sub-Account in the
future, since the net asset value will vary based not only on the type, quality
and maturities of the securities held in the corresponding Portfolio, but also
on changes in the current value of such securities and on changes in the
expenses of the Sub-Account and the corresponding Portfolio. These factors and
possible differences in the methods used to calculate total return should be
considered when comparing the total return of a Sub-Account to total returns
published for other investment companies or other investment vehicles. Total
return reflects the performance of both principal and income.


                                       4

     The Company may advertise examples of the effects of dollar cost averaging,
whereby an Owner periodically invests a fixed dollar amount in a Sub-Account,
thereby purchasing fewer Accumulation Units when prices are high and more
Accumulation Units when prices are low. While such a strategy does not assure a
profit nor guard against a loss in a declining market, the Owner's average cost
per Accumulation Unit can be lower than if fixed numbers of Accumulation Units
had been purchased at the same intervals. In evaluating dollar cost averaging,
Owners should consider their ability to continue purchasing Accumulation Units
during periods of low price levels.

     Performance information for any Sub-Account may be compared, in reports to
Owners and in advertising, to stock indices, other variable annuity separate
accounts or other products tracked by Lipper Analytical Services, or other
widely used independent research firms which rank variable annuities and
investment companies by overall performance, investment objectives and assets.
Unmanaged indices may assume the reinvestment of dividends but generally do not
reflect deductions for annuity charges and investment management costs.

FIXED ANNUITY PAYMENTS

     The Contracts provide only for fixed annuity payment options. The amount of
such payments is calculated by applying the Surrender Value, less any applicable
premium tax, at annuitization to the income payment rates for the income payment
option selected. Annuity payments will be the larger of:

     (a)        the income based on the rates shown in the Contract's Annuity
                Tables for the income payment option chosen; and

     (b)        the income calculated by applying the proceeds as a single
                premium at the Company's current rates in effect on the date of
                the first annuity payment for the same option.

        Annuity payments under any of the income payment options will not vary
in dollar amount and will not be affected by the future investment performance
of the Variable Account.

PART II - DISCUSSION REGARDING THE SELECT ADVISORS PORTFOLIOS

                                     SUMMARY

        Except as otherwise indicated herein, all capitalized terms have the
meanings assigned to them in the Prospectus.

        As described in the Prospectus, the Variable Account seeks to achieve
the investment objectives of each Sub-Account by investing all the investable
assets of the Sub-Account in a diversified open-end management investment
company having the same investment objectives as such Sub-Account. These
investment companies are, respectively, Emerging Growth Portfolio, International
Equity Portfolio, Balanced Portfolio, Growth & Income Portfolio, Income
Opportunity Portfolio, Bond Portfolio and Standby Income Portfolio (each a
"PORTFOLIO" or, collectively, the "PORTFOLIOS"). Detailed information regarding
the Emerging Growth, International Equity, Balanced, Income Opportunity and
Standby Income Portfolios (the "VIT PORTFOLIOS") is contained in the separate
prospectus of the Select Advisors Variable Insurance Trust (the "VI TRUST") that
accompanies the Prospectus. Detailed information regarding the Bond Portfolio
and the Growth & Income Portfolio (the "SAT PORTFOLIOS") is contained in Part II
of the Prospectus and this Statement of Additional Information.

        As disclosed in the Prospectus, Touchstone Advisors, Inc. (the
"ADVISOR") is the investment advisor of each Portfolio, and the specific
investments of each Portfolio are managed on a day-to-day basis by their
respective investment advisors (collectively, the "PORTFOLIO ADVISORS").
Investors Bank & Trust Company ("INVESTORS BANK" or the "ADMINISTRATOR") serves
as administrator and fund accounting agent to each Portfolio.

          INVESTMENT OBJECTIVES, TECHNIQUES, POLICIES AND RESTRICTIONS

                              INVESTMENT OBJECTIVES

        The investment objective(s) of each Sub-Account is described in the
Prospectus. There can be no assurance that any Sub-Account will achieve its
investment objective(s). See THE VI TRUST AND THE SA TRUST in the Prospectus.

                              INVESTMENT TECHNIQUES

        Since the investment characteristics of each Sub-Account will correspond
directly to those of the corresponding SAT Portfolio, the following is a
discussion of certain investments of and techniques employed by the SAT
Portfolios.

CERTIFICATES OF DEPOSIT AND BANKERS' ACCEPTANCES

        Certificates of deposit are receipts issued by a depository institution
in exchange for the deposit of funds. The issuer agrees to pay the amount
deposited plus interest to the bearer of the receipt on the date specified on
the certificate. The certificate usually can be traded in the secondary market
prior to maturity. Bankers' acceptances typically arise from short-term credit


                                       6
<PAGE>   68



arrangements designed to enable businesses to obtain funds to finance commercial
transactions. Generally, an acceptance is a time draft drawn on a bank by an
exporter or an importer to obtain a stated amount of funds to pay for specific
merchandise. The draft is then "accepted" by a bank that, in effect,
unconditionally guarantees to pay the face value of the instrument on its
maturity date. The acceptance may then be held by the accepting bank as an
earning asset or it may be sold in the secondary market at the going rate of
discount for a specific maturity. Although maturities for acceptances can be as
long as 270 days, most acceptances have maturities of six months or less.

COMMERCIAL PAPER

        Commercial paper consists of short-term (usually from 1 to 270 days)
unsecured promissory notes issued by corporations in order to finance their
current operations. A variable amount master demand note (which is a type of
commercial paper) represents a direct borrowing arrangement involving
periodically fluctuating rates of interest under a letter agreement between a
commercial paper issuer and an institutional lender pursuant to which the lender
may determine to invest varying amounts.

        For a description of commercial paper ratings, see the Appendix.

LOWER-RATED DEBT SECURITIES

        While the market for high yield corporate debt securities (commonly
known as "junk bonds") has been in existence for many years and has weathered
previous economic downturns, the 1980's brought a dramatic increase in the use
of such securities to fund highly leveraged corporate acquisitions and
restructuring. Past experience may not provide an accurate indication of future
performance of the high yield, high risk bond market, especially during periods
of economic recession. In fact, from 1989 to 1991, the percentage of lower-rated
debt securities that defaulted rose significantly above prior levels.

        The market for junk bonds may be thinner and less active than that for
higher rated debt securities, which can adversely affect the prices at which the
former are sold. If market quotations are not available, such lower-rated debt
securities will be valued in accordance with procedures establish by the Board
of Trustees of the SA Trust, including the use of outside pricing services.
Judgment plays a greater role in valuing high yield, high risk corporate debt
securities than is the case for securities for which more external sources for
quotations and last sale information is available. Adverse publicity and
changing investor perception may affect the ability of outside pricing services
to value lower-rated debt securities and the ability to dispose of these
securities.

        In considering investments for the Portfolio, the Portfolio Advisor will
attempt to identify those issuers of high yielding debt securities ("junk
bonds") whose financial condition is adequate to meet future obligations, has
improved or is expected to improve in the future. The Portfolio Advisor's
analysis focuses on relative values based on such factors as interest on
dividend coverage, asset coverage, earnings prospects and the experience and
managerial strength of the issuer.

        A Portfolio may choose, at its expense or in conjunction with others, to
pursue litigation or otherwise exercise its rights as a security holder to seek
to protect the interest of security holders if it determines this to be in the
best interest of the Portfolio.

        For a description of bond ratings, see the Appendix to the Prospectus.

ILLIQUID SECURITIES

        Historically, illiquid securities have included securities subject to
contractual or legal restrictions on resale because they have not been
registered under the Securities Act of 1933, as amended (the "1933 ACT"),
securities which are otherwise not readily marketable and repurchase agreements
having a maturity of longer than seven days. Securities which have not been
registered under the 1933 Act are referred to as "private placements" or
"restricted securities" and are purchased directly from the issuer or in the
secondary market. Investment companies do not typically hold a significant
amount of these restricted securities or other illiquid securities because of
the potential for delays on resale and uncertainty in valuation. Limitations on
resale may have an adverse effect on the marketability of portfolio securities
and a Portfolio might not be able to dispose of restricted or other illiquid
securities promptly or at reasonable prices and might thereby experience
difficulty satisfying redemptions within seven days. A Portfolio might also have
to register such restricted securities in order to dispose of them, resulting in
additional expense and delay. Adverse market conditions could impede such a
public offering of securities.

        In recent years, however, a large institutional market has developed for
certain securities that are not registered under the 1933 Act, including
repurchase agreements, commercial paper, foreign securities, municipal
securities and corporate bonds and notes. Institutional investors depend on an
efficient institutional market in which the unregistered security can be readily
resold or on an issuer's ability to honor a demand for repayment. The fact that
there are contractual or legal restrictions on resale of such investments to the
general public or to certain institutions may not be indicative of their
liquidity.

        The Securities and Exchange Commission (the "SEC") has adopted Rule
144A, which allows a broader institutional trading market for securities
otherwise subject to restriction on their resale to the general public. Rule
144A establishes a "safe harbor" from the registration requirements of the 1933
Act on resales of certain securities to qualified institutional buyers. The
Advisor and each Portfolio Advisor anticipate that the market for certain
restricted securities such as institutional commercial paper will expand further
as a result of this regulation and the development of automated systems for the
trading, clearance and settlement of unregistered securities of domestic and
foreign issuers, such as the PORTAL System sponsored by the National Association
of Securities Dealers, Inc.

        Each Portfolio Advisor will monitor the liquidity of Rule 144A
securities in the respective Portfolio's portfolio under the supervision of the
SA Trust's Board of Trustees. In reaching liquidity decisions, each Portfolio
Advisor will consider, among other things, the following factors: (1) the
frequency of trades and quotes for the security; (2) the number of dealers and
other potential purchasers wishing to purchase or sell the security; (3) dealer
undertakings to make a market in the security and (4) the nature of the security
and of the marketplace trades 



                                       8
<PAGE>   70



(e.g., the time needed to dispose of the security, the method of soliciting
offers and the mechanics of the transfer).

FOREIGN SECURITIES:  SPECIAL CONSIDERATIONS CONCERNING EASTERN EUROPE

        Investments in companies domiciled in Eastern European countries may be
subject to potentially greater risks than those of other foreign issuers. These
risks include: (i) potentially less social, political and economic stability;
(ii) the small current size of the markets for such securities and the low
volume of trading, which result in less liquidity and in greater price
volatility; (iii) certain national policies which may restrict the Portfolios'
investment opportunities, including restrictions on investment in issuers or
industries deemed sensitive to national interests; (iv) foreign taxation; (v)
the absence of developed legal structures governing private or foreign
investment or allowing for judicial redress for injury to private property; (vi)
the absence, until recently in certain Eastern European countries, of a capital
market structure or market-oriented economy; and (vii) the possibility that
recent favorable economic developments in Eastern Europe may be slowed or
reversed by unanticipated political or social events in such countries, or in
the Commonwealth of Independent States.

        So long as the Communist Party continues to exercise a significant or,
in some cases, a dominant role in Eastern European countries, investments in
such countries will involve risks of nationalization, expropriation and
confiscatory taxation. The former communist governments of a number of Eastern
European countries expropriated large amounts of private property in the past,
in many cases without adequate compensation, and there may be no assurance that
such expropriation will not occur in the future at the hands of either an
existing non-communist regime or upon the return to power of the Communist
Party. In the event of such expropriation, a Portfolio could lose a substantial
portion of any investments it has made in the affected countries. Further, no
accounting standards exist in Eastern European countries. Finally, even though
certain Eastern European currencies may be convertible into U.S. dollars, the
conversion rates may be artificial to the actual market values and may be
adverse to the interests of a Portfolio's shareholders.

LENDING PORTFOLIO SECURITIES

        By lending its securities, a Portfolio can increase its income by
continuing to receive interest on the loaned securities as well as by either
investing the cash collateral in short-term securities or obtaining yield in the
form of interest paid by the borrower when U.S. Government obligations are used
as collateral. There may be risks of delay in receiving additional collateral or
risks of delay in recovery of the securities or even loss of rights in the
collateral should the borrower of the securities fail financially. Each
Portfolio will adhere to the following conditions whenever its securities are
loaned: (i) the Portfolio must receive at least 100 percent cash collateral or
equivalent securities from the borrower; (ii) the borrower must increase this
collateral whenever the market value of the securities loaned, including accrued
interest, rises above the value of the collateral; (iii) the Portfolio must be
able to terminate the loan at any time; (iv) the Portfolio must receive
reasonable interest on the loan, as well as any dividends, interest or other
distributions on the loaned securities, and any in crease in market value; (v)
the Portfolio may pay only reasonable custodian fees in connection with the
loan; and (vi) voting rights on the loaned securities may pass to the borrower;
provided, however, that if a material event adversely 


                                       9
<PAGE>   71



affecting the investment occurs, the Board of Trustees must terminate the loan
and regain the right to vote the securities.

FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

        GENERAL

        The successful use of futures contracts and options on futures contracts
draws upon the Portfolio Advisor's skill and experience with respect to such
instruments and usually depends on the Portfolio Advisor's ability to forecast
interest rate and currency exchange rate movements correctly. Should interest or
exchange rates move in an unexpected manner, an SAT Portfolio may not achieve
the anticipated benefits of futures contracts or options on futures contracts or
may realize losses and thus will be in a worse position than if such strategies
had not been used. In addition, the correlation between movements in the price
of futures contracts or options on futures contracts and movements in the price
of the securities and currencies hedged or used for cover will not be perfect
and could produce unanticipated losses.

        FUTURES CONTRACTS

        An SAT Portfolio may enter into contracts for the purchase or sale for
future delivery of fixed-income securities or foreign currencies, or contracts
based on financial indices including any index of U.S. Government securities,
foreign government securities or corporate debt securities. U.S. futures
contracts have been designed by exchanges which have been designated "contracts
markets" by the Commodity Futures Trading Commission ("CFTC"), and must be
executed through a futures commission merchant, or brokerage firm, which is a
member of the relevant contract market. Futures contracts trade on a number of
exchange markets, and, through their clearing corporations, the exchanges
guarantee performance of the contracts as between the clearing members of the
exchange. An SAT Portfolio may enter into futures contracts which are based on
debt securities that are backed by the full faith and credit of the U.S.
Government, such as long-term U.S. Treasury bonds, Treasury Notes, Government
National Mortgage Association ("GNMA") modified pass-through mortgage-backed
securities and three-month U.S. Treasury bills. An SAT Portfolio may also enter
into futures contracts which are based on bonds issued by entities other than
the U.S. Government.

        At the same time a futures contract is purchased or sold, the SAT
Portfolio must allocate cash or securities as a deposit payment ("INITIAL
DEPOSIT"). It is expected that the initial deposit would be approximately 1-1/2%
to 5% of a contract's face value. Daily thereafter, the futures contract is
valued and the payment of "variation margin" may be required, since each day the
Portfolio would provide or receive cash that reflects any decline or increase in
the contract's value.

        At the time of delivery of securities pursuant to such a contract,
adjustments are made to recognize differences in value arising from the delivery
of securities with a different interest rate from that specified in the
contract. In some (but not many) cases, securities called for by a futures
contract may not have been issued when the contract was written.



                                       10
<PAGE>   72



        Although futures contracts by their terms call for the actual delivery
or acquisition of securities, in most cases the contractual obligation is
fulfilled before the date of the contract without having to make or take
delivery of the securities. The offsetting of a contractual obligation is
accomplished by buying (or selling, as the case may be) on a commodities
exchange an identical futures contract calling for delivery in the same month.
Such a transaction, which is effected through a member of an exchange, cancels
the obligation to make or take delivery of the securities. Since all
transactions in the futures market are made, offset or fulfilled through a
clearinghouse associated with the exchange on which the contracts are traded,
the SAT Portfolio will incur brokerage fees when it purchases or sells futures
contracts.

        The purpose of the acquisition or sale of a futures contract, in the
case of an SAT Portfolio which holds or intends to acquire fixed-income
securities, is to attempt to protect the Portfolio from fluctuations in interest
or foreign exchange rates without actually buying or selling fixed-income
securities or foreign currencies. For example, if interest rates were expected
to increase, the Portfolio might enter into futures contracts for the sale of
debt securities. Such a sale would have much the same effect as selling an
equivalent value of the debt securities owned by the Portfolio. If interest
rates did increase, the value of the debt security in the Portfolio would
decline, but the value of the futures contracts to the Portfolio would increase
at approximately the same rate, thereby keeping the net asset value of the
Portfolio from declining as much as it otherwise would have. The Portfolio could
accomplish similar results by selling debt securities and investing in bonds
with short maturities when interest rates are expected to increase. However,
since the futures market is more liquid than the cash market, the use of futures
contracts as an investment technique allows the Portfolio to maintain a
defensive position without having to sell its portfolio securities.

        Similarly, when it is expected that interest rates may decline, futures
contracts may be purchased to attempt to hedge against anticipated purchases of
debt securities at higher prices. Since the fluctuations in the value of futures
contracts should be similar to those of debt securities, an SAT Portfolio could
take advantage of the anticipated rise in the value of debt securities without
actually buying them until the market had stabilized. At that time, the futures
contracts could be liquidated and the Portfolio could then buy debt securities
on the cash market. When a Portfolio enters into a futures contract for any
purpose, the Portfolio will establish a segregated account with the Portfolio's
custodian to collateralize or "cover" the Portfolio's obligation consisting of
cash or liquid securities from its portfolio in an amount equal to the
difference between the fluctuating market value of such futures contracts and
the aggregate value of the initial and variation margin payments made by the
Portfolio with respect to such futures contracts.

        The ordinary spreads between prices in the cash and futures market, due
to differences in the nature of those markets, are subject to distortions.
First, all participants in the futures market are subject to initial deposit and
variation margin requirements. Rather than meeting additional variation margin
requirements, investors may close futures contracts through offsetting
transactions which could distort the normal relationship between the cash and
futures markets. Second, the liquidity of the futures market depends on
participants entering into offsetting transactions rather than making or taking
delivery. To the extent participants decide to make or take delivery, liquidity
in the futures market could be reduced, thus producing distortion. Third, from
the point of view of speculators, the margin deposit requirements in the futures
market are 



                                       11
<PAGE>   73


less onerous than margin requirements in the securities market. Therefore,
increased participation by speculators in the futures market may cause temporary
price distortions. Due to the possibility of distortion, a correct forecast of
general interest rate trends by the Portfolio Advisor may still not result in a
successful transaction.

        In addition, futures contracts entail risks. Although each applicable
Portfolio Advisor believes that use of such contracts will benefit the
respective Portfolio, if the Portfolio Advisor's investment judgment about the
general direction of interest rates is incorrect, a Portfolio's overall
performance would be poorer than if it had not entered into any such contract.
For example, if an SAT Portfolio has hedged against the possibility of an
increase in interest rates which would adversely affect the price of debt
securities held in its portfolio and interest rates decrease instead, the
Portfolio will lose part or all of the benefit of the increased value of its
debt securities which it has hedged because it will have offsetting losses in
its futures positions. In addition, in such situations, if a Portfolio has
insufficient cash, it may have to sell debt securities from its portfolio to
meet daily variation margin requirements. Such sales of bonds may be, but will
not necessarily be, at increased prices which reflect the rising market. An SAT
Portfolio may have to sell securities at a time when it may be disadvantageous
to do so.

        OPTIONS ON FUTURES CONTRACTS

        Each SAT Portfolio may purchase and write options on futures contracts
for hedging purposes. The purchase of a call option on a futures contract is
similar in some respects to the purchase of a call option on an individual
security. Depending on the pricing of the option compared to either the price of
the futures contract upon which it is based or the price of the underlying debt
securities, it may or may not be less risky than ownership of the futures
contract or underlying debt securities. As with the purchase of futures
contracts, when an SAT Portfolio is not fully invested it may purchase a call
option on a futures contract to hedge against a market advance due to declining
interest rates.

        The writing of a call option on a futures contract constitutes a partial
hedge against declining prices of the security or foreign currency which is
deliverable upon exercise of the futures contract. If the futures price at
expiration of the option is below the exercise price, an SAT Portfolio will
retain the full amount of the option premium which provides a partial hedge
against any decline that may have occurred in the Portfolio's holdings. The
writing of a put option on a futures contract constitutes a partial hedge
against increasing prices of the security or foreign currency which is
deliverable upon exercise of the futures contract. If the futures price at
expiration of the option is higher than the exercise price, the Portfolio will
retain the full amount of the option premium which provides a partial hedge
against any increase in the price of securities which the Portfolio intends to
purchase. If a put or call option the Portfolio has written is exercised, the
Portfolio will incur a loss which will be reduced by the amount of the premium
it receives. Depending on the degree of correlation between changes in the value
of its portfolio securities and changes in the value of its futures positions,
the Portfolio's losses from existing options on futures may to some extent be
reduced or increased by changes in the value of portfolio securities.


                                       12
<PAGE>   74



        The purchase of a put option on a futures contract is similar in some
respects to the purchase of protective put options on portfolio securities. For
example, a Portfolio may purchase a put option on a futures contract to hedge
its portfolio against the risk of rising interest rates.

        The amount of risk an SAT Portfolio assumes when it purchases an option
on a futures contract is the premium paid for the option plus related
transaction costs. In addition to the correlation risks discussed above, the
purchase of an option also entails the risk that changes in the value of the
underlying futures contract will not be fully reflected in the value of the
option purchased.

        An SAT Portfolio will not enter into any futures contracts or options on
futures contracts if immediately thereafter the amount of margin deposits on all
the futures contracts of the Portfolio and premiums paid on outstanding options
on futures contracts owned by the Portfolio would exceed 5% of the market value
of the total assets of the Portfolio.

        OPTIONS ON FOREIGN CURRENCIES

        Options on foreign currencies are used for hedging purposes in a manner
similar to that in which futures contracts on foreign currencies, or forward
contracts, are utilized. For example, a decline in the dollar value of a foreign
currency in which portfolio securities are denominated will reduce the 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 Portfolio may purchase put options on the foreign currency. If
the value of the currency does decline, a Portfolio will have the right to sell
such currency for a fixed amount in dollars and will thereby offset, in whole or
in part, the adverse effect on its portfolio which otherwise would have
resulted.

        Conversely, where a rise in the dollar value of a currency in which
securities to be acquired are denominated is projected, thereby increasing the
cost of such securities, an SAT Portfolio may purchase 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 the Portfolio deriving from purchases of foreign
currency options will be reduced by the amount of the premium and related
transaction costs. In addition, where currency exchange rates do not move in the
direction or to the extent anticipated, the Portfolio could sustain losses on
transactions in foreign currency options which would require it to forego a
portion or all of the benefits of advantageous changes in such rates.

        Options on foreign currencies may be written for the same types of
hedging purposes. For example, where an SAT Portfolio anticipates a decline in
the dollar value of foreign currency denominated securities due to adverse
fluctuations in exchange rates it could, instead of purchasing a put option,
write a call option on the relevant currency. If the expected decline occurs,
the options 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 an
anticipated increase in the dollar cost of securities to be acquired, the SAT
Portfolio could write a put option on the relevant currency which, if rates move
in the manner projected, will expire unexercised and allow the 



                                       13
<PAGE>   75


Portfolio to hedge such 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, and
only if rates move in the expected direction. If this does not occur, the option
may be exercised and the Portfolio would be required to purchase 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 Portfolio
also may be required to forego all or a portion of the benefits which might
otherwise have been obtained from favorable movements in exchange rates.

        Each SAT Portfolio may write covered call options on foreign currencies.
A call option written on a foreign currency by a Portfolio is "covered" if the
Portfolio 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 its custodian) upon conversion or exchange of other foreign currency
held in its portfolio. A call option is also covered if the Portfolio has a call
on the same foreign currency and in the same principal amount as the call
written where the exercise price of the call held (a) is equal to or less than
the exercise price of the call written or (b) is greater than the exercise price
of the call written if the difference is maintained by the Portfolio in cash and
liquid securities in a segregated account with its custodian.

        Each SAT Portfolio also may write call options on foreign currencies
that are not covered for cross-hedging purposes. 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 in the U.S. dollar value of a security which
the Portfolio owns or has the right to acquire and which is denominated in the
currency underlying the option due to an adverse change in the exchange rate. In
such circumstances, the Portfolio collateralizes the option by maintaining in a
segregated account with its custodian, cash or liquid securities in an amount
not less than the value of the underlying foreign currency in U.S. dollars
marked to market daily.

        ADDITIONAL RISKS OF OPTIONS ON FUTURES CONTRACTS, FORWARD CONTRACTS AND 
OPTIONS ON FOREIGN CURRENCIES

        Unlike transactions entered into by a Portfolio 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 national securities 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 purchaser of an
option cannot lose more than the amount of the premium plus related transaction
costs, this entire amount could be lost. Moreover, the option writer and a
trader of forward contracts could lose amounts substantially in excess of their
initial investments, due to the margin and collateral requirements associated
with such positions.


                                       14
<PAGE>   76



        Options on foreign currencies traded on national securities 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 transaction. In particular, all
foreign currency option positions entered into on a national securities exchange
are cleared and guaranteed by the Options Clearing Corporation ("OCC"), thereby
reducing the risk of counterparty default. Further, a liquid secondary market in
options traded on a national securities exchange may be more readily available
than in the over-the-counter market, potentially permitting an SAT Portfolio 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 governmental restrictions or taxes would prevent the orderly
settlement of foreign currency option exercises, or would result in undue
burdens on the OCC or its clearing member, impose special procedures on exercise
and settlement, such as technical changes in the mechanics of delivery or
currency, the fixing of dollar settlement prices or prohibitions on exercise.

        As in the case of forward contracts, certain options on foreign
currencies are traded over-the-counter and involve liquidity and credit risks
which may not be present in the case of exchange-traded currency options. An SAT
Portfolio's ability to terminate over-the-counter options will be more limited
than with exchange-traded options. It is also possible that broker-dealers
participating in over-the-counter options transactions will not fulfill their
obligations. Until such time as the staff of the SEC changes its position, each
Portfolio will treat purchased over-the-counter options and assets used to cover
written over-the-counter options as illiquid securities. With respect to options
written with primary dealers in U.S. Government securities pursuant to an
agreement requiring a closing purchase transaction at a formula price, the
amount of illiquid securities may be calculated with reference to the repurchase
formula.

        In addition, futures contracts, options on futures contracts, forward
contracts and options on foreign currencies may be traded on foreign exchanges.
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 the
Portfolio's ability to act upon economic events occurring in foreign markets
during nonbusiness 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) lesser trading volume.

OPTIONS ON SECURITIES

        The SAT Portfolios may write (sell), to a limited extent, only covered
call and put options ("COVERED OPTIONS") in an attempt to increase income.
However, the Portfolio may forgo the benefits of appreciation on securities sold
or may pay more than the market price on securities acquired pursuant to call
and put options written by the Portfolio.

        When an SAT Portfolio writes a covered call option, it gives the
purchaser of the option the right to buy the underlying security at the price
specified in the option (the "EXERCISE PRICE") by exercising the option at any
time during the option period. If the option expires unexercised, the Portfolio
will realize income in an amount equal to the premium received for writing the
option. If the option is exercised, a decision over which the SAT Portfolio has
no control, the Portfolio must sell the underlying security to the option holder
at the exercise price. By writing a covered call option, the Portfolio forgoes,
in exchange for the premium less the commission ("NET PREMIUM"), the opportunity
to profit during the option period from an increase in the market value of the
underlying security above the exercise price.

        When an SAT Portfolio writes a covered put option, it gives the
purchaser of the option the right to sell the underlying security to the
Portfolio at the specified exercise price at any time during the option period.
If the option expires unexercised, the Portfolio will realize income in the
amount of the premium received for writing the option. If the put option is
exercised, a decision over which the SAT Portfolio has no control, the Portfolio
must purchase the underlying security from the option holder at the exercise
price. By writing a covered put option, the Portfolio, in exchange for the net
premium received, accepts the risk of a decline in the market value of the
underlying security below the exercise price.

        An SAT Portfolio may terminate its obligation as the writer of a call or
put option by purchasing an option with the same exercise price and expiration
date as the option previously written. This transaction is called a "closing
purchase transaction." Where the Portfolio cannot effect a closing purchase
transaction, it may be forced to incur brokerage commissions or dealer spreads
in selling securities it receives or it may be forced to hold underlying
securities until an option is exercised or expires.

        When an SAT Portfolio writes an option, an amount equal to the net
premium received by the Portfolio is included in the liability section of the
Portfolio's Statement of Assets and Liabilities as a deferred credit. The amount
of the deferred credit will be subsequently marked to market to reflect the
current market value of the option written. The current market value of a traded
option is the last sale price or, in the absence of a sale, the mean between the
closing bid and asked price. If an option expires on its stipulated expiration
date or if the Portfolio enters into a closing purchase transaction, the
Portfolio will realize a gain (or loss if the cost of a closing purchase
transaction exceeds the premium received when the option was sold), and the
deferred credit related to such option will be eliminated. If a call option is
exercised, the SAT Portfolio will realize a gain or loss from the sale of the
underlying security and the proceeds of the sale will be increased by the
premium originally received. The writing of covered call options may be deemed
to involve the pledge of the securities against which the option is being
written.


                                       16
<PAGE>   78




        When an SAT Portfolio writes a call option, it will "cover" its
obligation by segregating the underlying security on the books of the
Portfolio's custodian or by placing liquid securities in a segregated account at
the Portfolio's custodian. When an SAT Portfolio writes a put option, it will
"cover" its obligation by placing liquid securities in a segregated account at
the Portfolio's custodian.

        An SAT Portfolio may purchase call and put options on any securities in
which it may invest. The Portfolio would normally purchase a call option in
anticipation of an increase in the market value of such securities. The purchase
of a call option would entitle the Portfolio, in exchange for the premium paid,
to purchase a security at a specified price during the option period. The
Portfolio would ordinarily have a gain if the value of the securities increased
above the exercise price sufficiently to cover the premium and would have a loss
if the value of the securities remained at or below the exercise price during
the option period.

        An SAT Portfolio 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 is permitted to invest. The purchase of a
put option would entitle the Portfolio, in exchange for the premium paid, to
sell a security, which may or may not be held in the Portfolio's portfolio, at a
specified price during the option period. The purchase of protective puts is
designed merely to offset or hedge against a decline in the market value of the
SAT Portfolio's portfolio securities. Put options also may be purchased by the
Portfolio for the purpose of affirmatively benefiting from a decline in the
price of securities which the Portfolio does not own. The Portfolio would
ordinarily recognize a gain if the value of the securities decreased below the
exercise price sufficiently to cover the premium and would recognize a loss if
the value of the securities remained at or above the exercise price. Gains and
losses on the purchase of protective put options would tend to be offset by
countervailing changes in the value of underlying portfolio securities.

        Each SAT Portfolio has adopted certain other nonfundamental policies
concerning option transactions which are discussed below. The Portfolio's
activities in options may also be restricted by the requirements of the Internal
Revenue Code of 1986, as amended (the "Code"), for qualification as a regulated
investment company.

        The hours of trading for options on securities 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. It is impossible to
predict the volume of trading that may exist in such options, and there can be
no assurance that viable exchange markets will develop or continue.

        An SAT Portfolio may engage in over-the-counter options transactions
with broker-dealers who make markets in these options. At present, approximately
ten broker-dealers, including several of the largest primary dealers in U.S.
Government securities, make these markets. The ability to terminate
over-the-counter option positions is more limited than with exchange-traded
option positions because the predominant market is the issuing broker rather
than an exchange, and may involve the risk that broker-dealers participating in
such transactions will not fulfill their obligations. To reduce this risk, the
Portfolio will purchase such options only from broker-


                                       17
<PAGE>   79



dealers who are primary government securities dealers recognized by the Federal
Reserve Bank of New York and who agree to (and are expected to be capable of)
entering into closing transactions, although there can be no guarantee that any
such option will be liquidated at a favorable price prior to expiration. The
Portfolio Advisor will monitor the creditworthiness of dealers with whom a
Portfolio enters into such options transactions under the general supervision of
the Board of Trustees.

OPTIONS ON SECURITIES INDEXES

        Options on securities indexes give the holder the right to receive a
cash settlement during the term of the option based upon the difference between
the exercise price and the value of the index. Such options will be used for the
purposes described above under "Options on Securities" or, to the extent allowed
by law, as a substitute for investment in individual securities.

        Options on securities indexes entail risks in addition to the risks of
options on securities. The absence of a liquid secondary market to close out
options positions on securities indexes is more likely to occur, although the
SAT Portfolio generally will only purchase or write such an option if the
Portfolio Advisor believes the option can be closed out.

        Use of options on securities indexes also entails the risk that trading
in such options may be interrupted if trading in certain securities included in
the index is interrupted. An SAT Portfolio will not purchase such options unless
the Advisor and the respective Portfolio Advisor each believes the market is
sufficiently developed such that the risk of trading in such options is no
greater than the risk of trading in options on securities.

        Price movements in an SAT Portfolio's portfolio may not correlate
precisely with movements in the level of an index and, therefore, the use of
options on indexes cannot serve as a complete hedge. Because options on
securities indexes require settlement in cash, the Portfolio Advisor may be
forced to liquidate portfolio securities to meet settlement obligations.

        When a Portfolio writes a put or call option on a securities index it
will cover the position by placing liquid securities in a segregated asset
account with the Portfolio's custodian.

FORWARD CURRENCY CONTRACTS

        Because, when investing in foreign securities, a Portfolio buys and
sells securities denominated in currencies other than the U.S. dollar and
receives interest, dividends and sale proceeds in currencies other than the U.S.
dollar, such Portfolios from time to time may enter into forward currency
transactions to convert to and from different foreign currencies and to convert
foreign currencies to and from the U.S. dollar. A Portfolio either enters into
these transactions on a spot (i.e., cash) basis at the spot rate prevailing in
the foreign currency exchange market or uses forward currency contracts to
purchase or sell foreign currencies.

        A forward currency contract is an obligation by a Portfolio to purchase
or sell a specific currency at a future date, which may be any fixed number of
days from the date of the contract. Forward currency contracts establish an
exchange rate at a future date. These contracts are transferable in the
interbank market conducted directly between currency traders (usually large


                                       18
<PAGE>   80



commercial banks) and their customers. A forward currency contract generally has
no deposit requirement and is traded at a net price without commission. Each SAT
Portfolio maintains with its custodian a segregated account of liquid securities
in an amount at least equal to its obligations under each forward currency
contract. Neither spot transactions nor forward currency contracts eliminate
fluctuations in the prices of the Portfolio's securities or in foreign exchange
rates, or prevent loss if the prices of these securities should decline.

        An SAT Portfolio may enter into foreign currency hedging transactions in
an attempt to protect against changes in foreign currency exchange rates between
the trade and settlement dates of specific securities transactions or changes in
foreign currency exchange rates that would adversely affect a portfolio position
or an anticipated investment position. Since consideration of the prospect for
currency parities will be incorporated into a Portfolio Advisor's long-term
investment decisions, an SAT Portfolio will not routinely enter into foreign
currency hedging transactions with respect to security transactions. However,
the Portfolio Advisors believe that it is important to have the flexibility to
enter into foreign currency hedging transactions when it determines that the
transactions would be in a Portfolio's best interest. Although these
transactions tend to minimize the risk of loss due to a decline in the value of
the hedged currency, at the same time they tend to limit any potential gain that
might be realized should the value of the hedged currency increase. The precise
matching of the forward currency contract amounts and the value of the
securities involved will not generally be possible because the future value of
such securities in foreign currencies will change as a consequence of market
movements in the value of such securities between the date the forward currency
contract is entered into and the date it matures. The projection of currency
market movements is extremely difficult, and the successful execution of a
hedging strategy is highly uncertain.

        While these contracts are not presently regulated by the CFTC, the CFTC
may in the future assert authority to regulate forward currency contracts. In
such event the SAT Portfolio's ability to utilize forward currency contracts in
the manner set forth in the Prospectus may be restricted. Forward currency
contracts may reduce the potential gain from a positive change in the
relationship between the U.S. dollar and foreign currencies. Unanticipated
changes in currency prices may result in poorer overall performance for the
Portfolio than if it had not entered into such contracts. The use of forward
currency contracts may not eliminate fluctuations in the underlying U.S. dollar
equivalent value of the prices of or rates of return on a Portfolio's foreign
currency denominated portfolio securities and the use of such techniques will
subject a Portfolio to certain risks.

        The matching of the increase in value of a forward currency 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. In addition, a Portfolio may not always be able to enter into forward
currency contracts at attractive prices and this will limit the SAT Portfolio's
ability to use such contract to hedge or cross-hedge its assets. Also, with
regard to a Portfolio's use of cross-hedges, there can be no assurance that
historical correlations between the movement of certain foreign currencies
relative to the U.S. dollar will continue. Thus, at any time poor correlation
may exist between movements in the exchange rates of the foreign currencies
underlying a Portfolio's cross-hedges and the movements in the exchange rates of
the foreign currencies in which the Portfolio's assets that are the subject of
such cross-hedges are denominated.

RATING SERVICES

        The ratings of nationally recognized statistical ratings organizations
represent their opinions as to the quality of the securities that they undertake
to rate. It should be emphasized, however, that ratings are relative and
subjective and are not absolute standards of quality. Although these ratings are
an initial criterion for selection of portfolio investments, the Portfolio
Advisors also make their own evaluation of these securities, subject to review
by the Board of Trustees of the SA Trust. After purchase by a Portfolio, an
obligation may cease to be rated or its rating may be reduced below the minimum
required for purchase by the Portfolio. Neither event would require a Portfolio
to eliminate the obligation from its portfolio, but a Portfolio Advisor will
consider such an event in its determination of whether a Portfolio should
continue to hold the obligation. A description of the ratings used herein and in
the Funds' Prospectuses is set forth in the Appendix to this Statement of
Additional Information.

                             INVESTMENT RESTRICTIONS

        The investment restrictions described below as "fundamental policies" of
each SAT Portfolio may not be changed with respect to any Portfolio without the
approval of a "majority of the outstanding voting securities" of the SAT
Portfolio. "MAJORITY OF THE OUTSTANDING VOTING SECURITIES" under the Investment
Company Act of 1940, as amended (the "1940 ACT"), and as used in this Statement
of Additional Information and the Prospectus, means, with respect to the
Portfolio, the lesser of (i) 67% or more of the outstanding voting securities of
the Portfolio present at a meeting, if the holders of more than 50% of the
outstanding voting securities of the Portfolio are present or represented by
proxy or (ii) more than 50% of the outstanding voting securities of the
Portfolio.

FUNDAMENTAL POLICIES

        The fundamental policies of each SAT Portfolio are described below. No
investment restriction of an SAT Portfolio shall prevent the Portfolio from
investing all of its assets in an open-end investment company with substantially
the same investment objectives.

        (1) No SAT Portfolio may borrow money or mortgage or hypothecate assets
of the Portfolio, except that, in an amount not to exceed 1/3 of the current
value of the Portfolio's net assets, it may borrow money (including through
reverse repurchase agreements, forward roll transactions involving
mortgage-backed securities or other investment techniques entered into for the
purpose of leverage), and except that it may pledge, mortgage or hypothecate not
more than 1/3 of such assets to secure such borrowings, provided that collateral
arrangements with respect to options and futures, including deposits of initial
deposit and variation margin, are not considered a pledge of assets for purposes
of this restriction and except that assets may be pledged to secure letters of
credit solely for the purpose of participating in a captive insurance company
sponsored by the Investment Company Institute; for additional related
restrictions, see clause (i) under the caption "Additional Restrictions" below.



                                       20
<PAGE>   82



        (2) No SAT Portfolio may underwrite securities issued by other persons
except insofar as the Portfolio may technically be deemed an underwriter under
the 1933 Act in selling a portfolio security.

        (3) No SAT Portfolio may make loans to other persons except: (a) through
the lending of the Portfolio's portfolio securities and provided that any such
loans not exceed 30% of the Portfolio's total assets (taken at market value);
(b) through the use of repurchase agreements or the purchase of short-term
obligations; or (c) by purchasing a portion of an issue of debt securities of
types distributed publicly or privately.

        (4) The Bond Portfolio may not purchase or sell real estate (including
limited partnership interests but excluding securities secured by real estate or
interests therein), interests in oil, gas or mineral leases, commodities or
commodity contracts (except futures and option contracts) in the ordinary course
of business (except that the Portfolio may hold and sell, for its portfolio,
real estate acquired as a result of the Portfolio's ownership of securities).

        (5) No SAT Portfolio may concentrate its investments in any particular
industry (excluding U.S. Government securities), but if it is deemed appropriate
for the achievement of a Portfolio's investment objective(s), up to 25% of its
total assets may be invested in any one industry.

        (6) No SAT Portfolio may issue any senior security (as that term is
defined in the 1940 Act) if such issuance is specifically prohibited by the 1940
Act or the rules and regulations promulgated thereunder, provided that
collateral arrangements with respect to options and futures, including deposits
of initial deposit and variation margin, are not considered to be the issuance
of a senior security for purposes of this restriction.

        (7) No SAT Portfolio may with respect to 75% of its total assets taken
at market value, invest in assets other than cash and cash items (including
receivables), U.S. Government securities, securities of other investment
companies, and other securities for purposes of this calculation limited in
respect of any one issuer to an amount not greater in value than 5% of the value
of the total assets of the Portfolio and to not more than 10% of the outstanding
voting securities of such issuer.

        (8) The Growth & Income Portfolio may not purchase or sell real estate
except that (a) the Portfolio may invest in (i) securities of entities that
invest or deal in real estate, mortgages, or interests therein and (ii)
securities secured by real estate or interests therein and (b) the Portfolio may
hold and sell real estate acquired as a result of the Portfolio's ownership of
securities.

        (9) The Growth & Income Portfolio may not purchase or sell interests in
oil, gas or mineral leases, commodities or commodity contracts (except futures
and option contracts) in the ordinary course of business.

<PAGE>   83



ADDITIONAL RESTRICTIONS

        Neither SAT Portfolio will, as a matter of operating policy (changeable
by the respective Board of Trustees without a shareholder vote) (except that no
operating policy shall prevent a Portfolio from investing all of its assets in
an open-end investment company with substantially the same investment
objectives), do any of the following:

     (i)   borrow money (including through reverse repurchase agreements or
           forward roll transactions involving mortgage-backed securities or
           similar investment techniques entered into for leveraging purposes),
           except that the Portfolio may borrow for temporary or emergency
           purposes up to 10% of its total assets; provided, however, that no
           Portfolio may purchase any security while outstanding borrowings
           exceed 5%;

    (ii)   pledge, mortgage or hypothecate for any purpose in excess of 10% of
           the Portfolio's total assets (taken at market value), provided that
           collateral arrangements with respect to options and futures,
           including deposits of initial deposit and variation margin, and
           reverse repurchase agreements are not considered a pledge of assets
           for purposes of this restriction;

   (iii)   purchase any security or evidence of interest therein on margin,
           except that such short-term credit as may be necessary for the
           clearance of purchases and sales of securities may be obtained and
           except that deposits of initial deposit and variation margin may be
           made in connection with the purchase, ownership, holding or sale of
           futures;

    (iv)   sell any security which it does not own unless by virtue of its
           ownership of other securities it has at the time of sale a right to
           obtain securities, without payment of further consideration,
           equivalent in kind and amount to the securities sold and provided
           that if such right is conditional the sale is made upon the same
           conditions;

     (v)   invest for the purpose of exercising control or management;

    (vi)   purchase securities issued by any investment company except by
           purchase 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 except when such purchase, though not made in
           the open market, is part of a plan of merger or consolidation;
           provided, however, that securities of any investment company will not
           be purchased for the Portfolio if such purchase at the time thereof
           would cause: (a) more than 10% of the Portfolio's total assets (taken
           at the greater of cost or market value) to be invested in the
           securities of such issuers; (b) more than 5% of the Portfolio's total
           assets (taken at the greater of cost or market value) to be invested
           in any one investment company; or (c) more than 3% of the outstanding
           voting securities of any such issuer to be held for the Portfolio;
           provided further that, except in the case of a merger or
           consolidation, the Portfolio shall not purchase any securities of any
           open-end investment company unless the Portfolio (1) waives the
           investment advisory fee, with respect to assets invested in other
           open-end investment companies and (2) incurs no sales charge in
           connection with the investment;


                                       22
<PAGE>   84



   (vii)   invest more than 15% of the Portfolio's net assets (taken at the
           greater of cost or market value) in securities that are illiquid or
           not readily marketable (defined as a security that cannot be sold in
           the ordinary course of business within seven days at approximately
           the value at which the Portfolio has valued the security) excluding
           (a) Rule 144A securities determined to be liquid by the Board of
           Trustees of the SA Trust; and (b) commercial paper that is sold under
           Section 4(2) of the Securities Act of 1933 which is not traded flat
           or in default as to interest or principal and either (i) is rated in
           one of the two highest categories by at least two nationally
           recognized statistical rating organizations and the Board of Trustees
           of the SA Trust have determined the commercial paper to be liquid; or
           (ii) is rated in one of the two highest categories by one nationally
           recognized statistical rating agency and the Board of Trustees of the
           SA Trust have determined that the commercial paper is equivalent
           quality and is liquid);

  (viii)   invest more than 5% of the Portfolio's total assets in securities
           issued by issuers that (including the period of operation of any
           predecessor or unconditional guarantor of such issuer) have been in
           operation less than three years;

    (ix)   invest more than 10% of the Portfolio's total assets in securities
           that are restricted from being sold to the public without
           registration under the Securities Act of 1933 (other than Rule 144A
           securities deemed to be liquid by the Trustees of the SA Trust);

     (x)   purchase securities of any issuer if such purchase at the time
           thereof would cause the Portfolio to hold more than 10% of any class
           of securities of such issuer, for which purposes all indebtedness of
           an issuer shall be deemed a single class and all preferred stock of
           an issuer shall be deemed a single class, except that futures or
           option contracts shall not be subject to this restriction;

    (xi)   purchase or retain in the Portfolio's portfolio any securities issued
           by an issuer any of whose officers, directors, trustees or security
           holders is an officer or Trustee of the SA Trust, or is an officer or
           partner of the Advisor, if after the purchase of the securities of
           such issuer for the Portfolio one or more of such persons owns
           beneficially more than 1/2 of 1% of the shares or securities, or
           both, all taken at market value, of such issuer, and such persons
           owning more than 1/2 of 1% of such shares or securities together own
           beneficially more than 5% of such shares or securities, or both, all
           taken at market value;

   (xii)   invest more than 5% of the Portfolio's net assets in warrants (valued
           at the lower of cost or market) (other than warrants acquired by the
           Portfolio as part of a unit or attached to securities at the time of
           purchase), but not more than 2% of the Portfolio's net assets may be
           invested in warrants not listed on the New York Stock Exchange Inc.
           ("NYSE") or the American Stock Exchange;

  (xiii)   make short sales of securities or maintain a short position, unless
           at all times when a short position is open it owns an equal amount of
           such securities or securities convertible into or exchangeable,
           without payment of any further consideration, for securities of the
           same issue and equal in amount to, the securities sold short, and
           unless not more than 10% of the Portfolio's net assets (taken at
           market value) is represented by

           such securities, or securities convertible into or exchangeable for
           such securities, at any one time (the Portfolios have no current
           intention to engage in short selling);

   (xiv)   purchase puts, calls, straddles, spreads and any combination thereof
           if by reason thereof the value of the Portfolio's aggregate
           investment in such classes of securities will exceed 5% of its total
           assets;

    (xv)   write puts and calls on securities unless each of the following
           conditions are met: (a) the security underlying the put or call is
           within the investment policies of the Portfolio and the option is
           issued by the OCC, except for put and call options issued by non-U.S.
           entities or listed on non-U.S. securities or commodities exchanges;
           (b) the aggregate value of the obligations underlying the puts
           determined as of the date the options are sold shall not exceed 50%
           of the Portfolio's net assets; (c) the securities subject to the
           exercise of the call written by the Portfolio must be owned by the
           Portfolio at the time the call is sold and must continue to be owned
           by the Portfolio until the call has been exercised, has lapsed, or
           the Portfolio has purchased a closing call, and such purchase has
           been confirmed, thereby extinguishing the Portfolio's obligation to
           deliver securities pursuant to the call it has sold; and (d) at the
           time a put is written, the Portfolio establishes a segregated account
           with its custodian consisting of cash or liquid securities equal in
           value to the amount the Portfolio will be obligated to pay upon
           exercise of the put (this account must be maintained until the put is
           exercised, has expired, or the Portfolio has purchased a closing put,
           which is a put of the same series as the one previously written); and


   (xvi)   buy and sell puts and calls on securities, stock index futures or
           options on stock index futures, or financial futures or options on
           financial futures unless such options are written by other persons
           and: (a) the options or futures are offered through the facilities of
           a national securities association or are listed on a national
           securities or commodities exchange, except for put and call options
           issued by non-U.S. entities or listed on non-U.S. securities or
           commodities exchanges; (b) the aggregate premiums paid on all such
           options which are held at any time do not exceed 20% of the
           Portfolio's total net assets; and (c) the aggregate margin deposits
           required on all such futures or options thereon held at any time do
           not exceed 5% of the Portfolio's total assets.

         Each Portfolio also will comply with the applicable investment
limitations found in the laws and regulations of any state in which the
corresponding Sub-Account investing in the Portfolio is registered.

PORTFOLIO TRANSACTIONS AND BROKERAGE COMMISSIONS

         The Portfolio Advisors for the SAT Portfolios are responsible for
decisions to buy and sell securities, futures contracts and options on such
securities and futures for each SAT Portfolio, the selection of brokers, dealers
and futures commission merchants to effect transactions and the negotiation of
brokerage commissions, if any. Broker-dealers may receive brokerage commissions
on portfolio transactions, including options, futures and options on futures
transactions and the purchase and sale of underlying securities upon the
exercise of 



                                       24
<PAGE>   86


options. Orders may be directed to any broker-dealer or futures commission
merchant, including to the extent and in the manner permitted by applicable law,
the Advisor, the Portfolio Advisors or their subsidiaries or affiliates.
Purchases and sales of certain portfolio securities on behalf of a Portfolio are
frequently placed by the Portfolio Advisor with the issuer or a primary or
secondary market-maker for these securities on a net basis, without any
brokerage commission being paid by the Portfolio. Trading does, however, involve
transaction costs. Transactions with dealers serving as market-makers reflect
the spread between the bid and asked prices. Purchases of underwritten issues
may be made which will include an underwriting fee paid to the underwriter.

         The Portfolio Advisors seek to evaluate the overall reasonableness of
any brokerage commissions paid through familiarity with commissions charged on
comparable transactions, as well as by comparing commissions paid by the
Portfolio to reported commissions. In placing orders for the purchase and sale
of securities for a Portfolio, the Portfolio Advisors take into account such
factors as price, commission (if any, negotiable in case of national securities
exchange transactions), size of order, difficulty of execution and skill
required of the executing broker-dealer. The Portfolio Advisors review on a
routine basis commission rates, execution and settlement services performed,
making internal and external comparisons.

         The Portfolio Advisors are authorized, consistent with Section 28(e) of
the Securities Exchange Act of 1934, as amended, when placing portfolio
transactions for a Portfolio with a broker to pay a brokerage commission (to the
extent applicable) in excess of that which another broker might have charged for
effecting the same transaction on account of the receipt of research, market or
statistical information. The term "research, market or statistical information"
includes 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; and furnishing analyses and reports concerning
issuers, industries, securities, economic factors and trends, portfolio strategy
and the performance of accounts. A Portfolio Advisor may use this research
information in managing an SAT Portfolio's assets, as well as the assets of
other clients.

         Consistent with the policy stated above, the Rules of Fair Practice of
the National Association of Securities Dealers, Inc. and such other policies as
the Board of Trustees may determine, the Portfolio Advisors may consider sales
of shares of the SA Trust and of other investment company clients of the Advisor
or the Portfolio Advisor as a factor in the selection of broker-dealers to
execute portfolio transactions. The Portfolio Advisor will make such allocations
if commissions are comparable to those charged by nonaffiliated, qualified
broker-dealers for similar services.

         Except for implementing the policies stated above, there is no
intention to place portfolio transactions with particular brokers or dealers or
groups thereof. In effecting transactions in over-the-counter securities, orders
are placed with the principal market-makers for the security being traded
unless, after exercising care, it appears that more favorable results are
available otherwise.

         Although certain research, market and statistical information from
brokers and dealers can be useful to a Portfolio and to the corresponding
Portfolio Advisor, it is the opinion of the management of the Portfolios that
such information is only supplementary to the Portfolio Advisor's own research
effort, since the information must still be analyzed, weighed and 



                                       25
<PAGE>   87


reviewed by the Portfolio Advisor's staff. Such information may be useful to the
Portfolio Advisor in providing services to clients other than the SAT
Portfolios, and not all such information is used by the Portfolio Advisor in
connection with such Portfolios. Conversely, such information provided to the
Portfolio Advisor by brokers and dealers through whom other clients of the
Portfolio Advisor effect securities transactions may be useful to the Portfolio
Advisor in providing services to the Portfolios.

         In certain instances there may be securities which are suitable for an
SAT Portfolio as well as for one or more of the Advisor's other clients,
including Portfolios of the SA Trust that are not available to the Sub-Accounts.
Investment decisions for a Portfolio and for the Portfolio Advisor's other
clients are made with a view to achieving their respective investment
objectives. It may develop that a particular security is bought or sold for only
one client even though it might be held by, or bought or sold for, other
clients. Likewise, a particular security may be bought for one or more clients
when one or more clients are selling that same security. Some simultaneous
transactions are inevitable when several clients receive investment advice from
the same investment advisor, particularly when the same security is suitable for
the investment objectives of more than one client. When two or more clients are
simultaneously engaged in the purchase or sale of the same security, the
securities are allocated among clients in a manner believed to be equitable to
each. It is recognized that in some cases this system could have a detrimental
effect on the price or volume of the security as far as a Portfolio is
concerned. However, it is believed that the ability of a Portfolio to
participate in volume transactions will produce better executions for the
Portfolio.

         For the period November 21, 1994 (commencement of operations) to
December 31, 1994, and for the fiscal years ended December 31, 1995 and 1996,
the aggregate brokerage commissions paid by each Portfolio is as follows:

</TABLE>


                   VALUATION OF SECURITIES; REDEMPTION IN KIND

         The value of each security for which readily available market
quotations exists is based on a decision as to the broadest and most
representative market for such security. The value of such security is based
either on the last sale price on a national securities exchange, or, in the
absence of recorded sales, at the readily available closing bid price on such
exchanges, or at the quoted bid price in the over-the-counter market. Securities
listed on a foreign exchange are valued at the last quoted sale price available
before the time net assets are valued. Unlisted securities are valued at the
average of the quoted bid and asked prices in the over-the-counter market. Debt
securities are valued by a pricing service which determines valuations based
upon market transactions for normal, institutional-size trading units of similar
securities. Securities or other assets for which market quotations are not
readily available are valued at fair value in accordance 


                                       26
<PAGE>   88



with procedures established by the SA Trust. Such procedures include the use of
independent pricing services, which use prices based upon yields or prices of
securities of comparable quality, coupon, maturity and type; indications as to
values from dealers; and general market conditions. All portfolio securities
with a remaining maturity of less than 60 days are valued at amortized cost,
which approximates market.

         The accounting records of the Portfolios are maintained in U.S.
dollars. The market value of investment securities, other assets and liabilities
and forward contracts denominated in foreign currencies are translated into U.S.
dollars at the prevailing exchange rates at the end of the period. Purchases and
sales of securities, income receipts, and expense payments are translated at the
exchange rate prevailing on the respective dates of such transactions. Reported
net realized gains and losses on foreign currency transactions represent net
gains and losses from sales and maturities of forward currency contracts,
disposition of foreign currencies, currency gains and losses realized between
the trade and settlement dates on securities transactions and the difference
between the amount of net investment income accrued and the U.S. dollar amount
actually received.

         The problems inherent in making a good faith determination of value are
recognized in the codification effected by SEC Financial Reporting Release No. 1
("FRR 1" (formerly Accounting Series Release No. 113)) which concludes that
there is "no automatic formula" for calculating the value of restricted
securities. It recommends that the best method simply is to consider all
relevant factors before making any calculation. According to FRR 1 such factors
would include consideration of the:

                  type of security involved, financial statements, cost at date
                  of purchase, size of holding, discount from market value of
                  unrestricted securities of the same class at the time of
                  purchase, special reports prepared by analysts, information as
                  to any transactions or offers with respect to the security,
                  existence of merger proposals or tender offers affecting the
                  security, price and extent of public trading in similar
                  securities of the issuer or comparable companies, and other
                  relevant matters.

         To the extent that an SAT Portfolio purchases securities which are
restricted as to resale or for which current market quotations are not
available, the Portfolio Advisor will value such securities based upon all
relevant factors as outlined in FRR 1.

         Each SAT Portfolio reserves the right, if conditions exist which make
cash payments undesirable, to honor any request for redemption or repurchase
order by making payment in whole or in part in readily marketable securities
chosen by the SA Trust or the Portfolio, as the case may be, and valued as they
are for purposes of computing the Portfolio's net asset value (a redemption in
kind). If payment is made in securities, an investor, including the
corresponding Sub-Account, may incur transactions expenses in converting these
securities into cash. The SA Trust, on behalf of each Portfolio, has elected,
however, to be governed by Rule 18f-1 under the 1940 Act as a result of which
each Portfolio is obligated to redeem shares or beneficial interests, as the
case may be, with respect to any one investor during any 90-day period, solely
in cash up 


                                       27
<PAGE>   89


to the lesser of $250,000 or 1% of the net asset value of the Portfolio, as the
case may be, at the beginning of the period.

         Each investor in an SAT Portfolio, including the corresponding
Sub-Account, may add to or reduce its investment in the Portfolio on each day
that the NYSE is open for business. As of 4:00 p.m., New York time, on each such
day, the value of each investor's interest in a Portfolio will be determined by
multiplying the net asset value of the Portfolio by the percentage representing
that investor's share of the aggregate beneficial interests in the Portfolio.
Any additions or reductions which are to be effected on that day will then be
effected. The investor's percentage of the aggregate beneficial interests in a
Portfolio will then be recomputed as the percentage equal to the fraction (i)
the numerator of which is the value of such investor's investment in the
Portfolio as of 4:00 p.m. on such day plus or minus, as the case may be, the
amount of net additions to or reductions in the investor's investment in the
Portfolio effected on such day and (ii) the denominator of which is the
aggregate net asset value of the Portfolio as of 4:00 p.m. on such day plus or
minus, as the case may be, the amount of net additions to or reductions in the
aggregate investments in the Portfolio by all investors in the Portfolio. The
percentage so determined will then be applied to determine the value of the
investor's interest in the Portfolio as of 4:00 p.m. on the following day the
NYSE is open for trading.

invest).

ADVISOR, PORTFOLIO ADVISORS, ADMINISTRATOR AND SPONSOR

         ADVISOR

         The Advisor provides service to each Portfolio of the SA Trust pursuant
to an Investment Advisory Agreement with the SA Trust (the "ADVISORY
AGREEMENT"). The services provided by the Advisor consist of directing and
supervising each Portfolio Advisor, reviewing and evaluating the performance of
each Portfolio Advisor and determining whether or not any Portfolio Advisor
should be replaced. The Advisor furnishes at its own expense all facilities and
personnel necessary in connection with providing these services. The Advisory
Agreement will continue in effect if such continuance is specifically approved
at least annually by the Board of Trustees of the SA Trust and by a majority of
the Trustees who are not parties to the Advisory Agreement or interested persons
of any such party, at a meeting called for the purpose of voting on the Advisory
Agreement.


                                       30
<PAGE>   92



         The Advisory Agreement is terminable, with respect to a Portfolio,
without penalty on not more than 60 days' nor less than 30 days' written notice
by the SA Trust, when authorized either by majority vote of the investors in the
Portfolio (with the vote of each being in proportion to the amount of their
investment) or by a vote of a majority of the Board of Trustees or by the
Advisor, and will automatically terminate in the event of its assignment. The
Advisory Agreement provides that neither the Advisor nor its personnel shall be
liable for any error of judgment or mistake of law or for any loss arising out
of any investment or for any act or omission in its services to the Portfolios,
except for willful misfeasance, bad faith or gross negligence or reckless
disregard of its or their obligations and duties under the Advisory Agreement.

         The Prospectus contains a description of fees payable to the Advisor
for services under the Advisory Agreement.

         For the period November 21, 1994 (commencement of operations) to
December 31, 1994 and for the fiscal years ended December 31, 1995 and 1996,
each SAT Portfolio incurred the following investment advisory fees equal on an
annual basis to the following percentages of the average daily net assets of the
Portfolio.

         For the period November 21, 1994 to December 31, 1994, and for the
fiscal years ended December 31, 1995 and 1996, the Advisor, under the terms of
the Sponsor Agreement, reimbursed the Growth & Income Portfolio $14,346, $85,300
and $34,126, and reimbursed the Bond Portfolio $15,160, $69,754 and $26,226,
respectively. See "Sponsor."

         PORTFOLIO ADVISORS

         The Advisor has, in turn, entered into a portfolio advisory agreement
(each a "PORTFOLIO AGREEMENT") with each Portfolio Advisor selected by the
Advisor for a Portfolio. Under the direction of the Advisor and, ultimately, of
the Board of Trustees of the SA Trust, each Portfolio Advisor is responsible for
making all of the day-to-day investment decisions for the respective Portfolio.

         Each Portfolio Advisor furnishes at its own expense all facilities and
personnel necessary in connection with providing these services. Each Portfolio
Agreement contains provisions similar to those described above with respect to
the Advisory Agreement.

         ADMINISTRATOR, CUSTODIAN AND FUND ACCOUNTING AGENT

         Pursuant to Administration and Fund Accounting Agreements, Investors
Bank supervises the overall administration of the Trust, including but not
limited to, accounting, clerical and bookkeeping services; daily calculation of
net asset values; preparation and filing of all documents required for
compliance by the Trust with applicable laws and regulations. Investors Bank
also provides persons to serve as officers of the Trust. As custodian, Investors
Bank holds cash, securities and other assets of the Trust.

         The Trust's Prospectus contains a description of fees payable to
Investors Bank for its services as administrator, fund accounting agent and
custodian.

         Prior to December 1, 1996, Signature Financial Services, Inc.
("Signature") served as administrator and fund accounting agent to the Trust.

         Each of the Administration, Fund Accounting and Custodian Agreements
(collectively, the "Agreements") provide that neither Investors Bank nor its
personnel shall be liable for any error of judgment or mistake of law or for any
act or omission, except for wilful misfeasance, bad faith or negligence (gross
negligence in respect of the Custodian Agreement) in the performance of its or
their duties or by reason of disregard (reckless disregard in respect of the
Custodian Agreement) of its or their obligations and duties under the
Agreements.

         Each Agreement may not be assigned without the consent of the
non-assigning party, and may be terminated after its initial term, with respect
to a Portfolio, without penalty by majority vote of the shareholders of the
Portfolio or by either party on not more than 60 days' written notice.

         State Street Bank and Trust Company ("State Street") serves as transfer
agent of the Trust pursuant to a transfer agency agreement. Under its transfer
agency agreement with the Trust, State Street maintains the shareholder account
records for each Fund, handles certain communications between shareholders and
the Trust and causes to be distributed any dividends and distributions payable
by the Trust. State Street may be reimbursed by the Trust for its out-of-pocket
expenses.

         For the period November 21, 1994 (commencement of operations) to
December 31, 1994, and for the fiscal years ended December 31, 1995 and 1996,
the Growth & Income Portfolio incurred $4,384, $46,743 and $56,786,
respectively, in administrative and fund accounting fees, including
out-of-pocket expenses. For the same periods, the Bond Portfolio incurred
$4,384, $47,124 and $56,396, respectively, in administrative and fund accounting
fees, including out-of-pocket expenses.

         SPONSOR

         Touchstone Advisors, Inc. serves also (in addition to its services as
Advisor to each Portfolio of the SA Trust) as the sponsor ("SPONSOR") of each
SAT Portfolio pursuant to a sponsor agreement (the "SPONSOR AGREEMENT"). Under
each Sponsor Agreement, the Sponsor 


                                       32
<PAGE>   94


provides oversight of the various service providers to each of the SA Trust and
the SAT Portfolios, including the Administrator and the Custodian. For its
services in this regard, the Sponsor is paid a fee, on an annual basis, equal to
0.20% of the average daily net assets of each Portfolio. The Sponsor Agreement
may be terminated by the Sponsor on not less than 30 days prior written notice
and by the SA Trust, as to any Portfolio. The Sponsor has advised the SA Trust
that it will waive all fees under the Sponsor Agreement through April 30, 1998.

COUNSEL AND INDEPENDENT ACCOUNTANTS

         Frost & Jacobs LLP, 2500 PNC Center, 201 East Fifth Street, Cincinnati,
Ohio 45202, serves as counsel to the SA Trust and each SAT Portfolio. Coopers &
Lybrand L.L.P., One Post Office Square, Boston, Massachusetts 02109, acts as
independent accountants of the SA Trust and each SAT Portfolio.

                          ORGANIZATION OF THE SA TRUST

         Interests in the SA Trust do not have cumulative voting rights, which
means that holders of more than 50% of such interests (which includes the
interests held by other investors in the SAT Portfolios (Growth & Income and
Bond) and the interests of other investors in Portfolios of the SA Trust that
are not available for investment by the Sub-Accounts) voting for the election of
Trustees can elect all Trustees. Accordingly, it is unlikely that Owners having
Contract Value in the Sub-Accounts that invest in the SAT Portfolios will be
able to control the election of any of the Trustees. Matters affecting the SAT
Portfolios are generally decided by separate vote of each SAT Portfolio, except
with respect to the election of Trustees and the ratification of the selection
of independent accountants.

         The SA Trust, in the Portfolios of which all of the assets of the
corresponding Sub-Accounts will be invested, is organized as a trust under the
laws of the State of New York. Each Sub-Account and other entity investing in an
SAT Portfolio (e.g., other investment companies, insurance company separate
accounts and common and commingled trust funds) will each be liable for all
obligations of the Portfolio. However, the risk of a Sub-Account incurring
financial loss on account of such liability is limited to circumstances in which
both inadequate insurance existed and the Portfolio itself was unable to meet
its obligations. Accordingly, the SA Trust's Trustees believe that no
Sub-Account (or any Owner having Contract Value therein) will be adversely
affected by reason of the Sub-Account's investing in the corresponding
Portfolio.

                                    TAXATION
TAXATION OF THE PORTFOLIOS

         Each of the Portfolios will be classified as a partnership for federal
income tax purposes. Furthermore, none of the Portfolios will be a "publicly
traded partnership" for purposes of Section 7704 of the Code. Consequently, the
Portfolios will not be subject to federal income taxation. Instead, each entity
that invests in a Portfolio must take into account, in computing its federal
income tax liability, its share of the Portfolio's income, gains, losses,
deductions, credits and tax preference items for the year, without regard to the
amount of cash distributions it has received during the year from the Portfolio.
Although no Portfolio will be subject to federal income tax, each will file
appropriate income tax returns as required by the Code.

SUB-ACCOUNT DIVERSIFICATION

         Each Sub-Account that invests in a Portfolio will be treated as owning
a proportionate interest in the assets held by the Portfolio for purposes of
determining whether the Sub-Account is adequately diversified within the meaning
of Section 817(h) of the Code. The diversification requirement must be satisfied
in order for the Contract to be treated as an "annuity contract" under the Code.
