                   The date of this Prospectus is July 15, 1999
                   --------------------------------------------




     This Prospectus describes group annuity contracts  ("Contracts") offered by
American  United  Life  Insurance  Company(R)  ("AUL"  or  the  "Company").  Any
employer,  association,  or  other  group  may  enter  into  the  Contracts  and
specialized  plans that do not  qualify for  favorable  tax  treatment,  such as
non-qualified Section 457 plans may also be sold.

     This Prospectus  describes contracts that allow ongoing  contributions that
can vary in  amount  and  frequency  ("Recurring  Contribution  Contracts")  and
contracts that allow only a single contribution to be made ("Single Contribution
Contracts").  All of the  Contracts  provide for the  accumulation  of values on
either a variable  basis,  a fixed basis,  or both.  The Contracts  also provide
several options for fixed annuity payments to begin on a future date.

     A Participant may allocate  contributions to the AUL American Unit Trust, a
separate account of AUL (the "Variable Account"). The Variable Account, in turn,
invests in shares of mutual fund portfolios. The Participant does not own shares
of the mutual fund, only units in the Variable Account.  The Variable Account is
divided  into  Investment  Accounts.  These  Investment  Accounts  invest in the
corresponding  Portfolios  offered  by  the  mutual  funds.  For  example,  if a
Participant  decides to allocate his  contributions  to the AUL American  Equity
Investment Account,  those contributions would buy units of the Variable Account
which,  in turn,  would  buy  shares  of the AUL  American  Series  Fund  Equity
Portfolio.  Contributions  allocated  to a  variable  Investment  Account of the
Variable Account  fluctuate in value depending on the investment  performance of
the corresponding  mutual fund portfolio.  These amounts are not guaranteed.  In
the  alternative,  a  participant  may  allocate  contributions  to AUL's  Fixed
Account. These contributions will earn interest at rates that are paid by AUL as
described in "The Fixed  Account." A Participant may allocate  contributions  to
one or more of the Investment  Accounts,  but not all of the Investment Accounts
may be available under a specific Contract.

  The Mutual Fund Portfolios that may be offered under the contracts are:

decreases  from, and  accumulations  in the Investment  Accounts of the Variable
Account during the Accumulation Period.

                                    SUMMARY

     This  summary  is  intended  to  provide  a  brief  overview  of  the  more
significant  aspects of the Contracts.  Later sections of this  Prospectus,  the
Statement  of  Additional  Information,  and the  Contracts  themselves  provide
further detail.  Unless the context indicates otherwise,  the discussion in this
summary  and the  remainder  of the  Prospectus  relates  to the  portion of the
Contracts involving the Variable Account.  The pertinent Contract and "The Fixed
Account" section of this Prospectus briefly describe the Fixed Account.

PURPOSE OF THE CONTRACTS


     The  group  variable  annuity  contracts  ("Contracts")  described  in this
Prospectus were generally  designed by AUL for use with group  retirement  plans
that qualify for favorable  tax-deferred  treatment as retirement programs under
Sections 401, 403(b),  408, or 457 of the Internal  Revenue Code  (collectively,
the  "Plans").  A Contract  presents a dynamic  concept in  retirement  planning
designed  to give  employers  and  employees  and  other  Participants  in Plans
flexibility  to attain  their  investment  goals.  A Contract  provides  for the
accumulation of values on a variable basis, a fixed basis, or both, and provides
several options for fixed annuity  payments.  During the Accumulation  Period, a
Participant can allocate contributions to the various Investment Accounts of the
Variable Account or to the Fixed Account.  See the Section "The Contracts" later
in this Prospectus.


TYPES OF CONTRACTS


     AUL  offers   several  types  of  contracts  that  are  described  in  this
Prospectus.  With Recurring  Contribution  Contracts,  contributions may vary in
amount and frequency,  subject to the  limitations  described  below.  Recurring
Contribution Contracts are available for use in connection with retirement plans
that meet the requirements of Sections 401, 403(b),  408, or 457 of the Internal
Revenue Code.  AUL also offers  single  contribution  contracts  which require a
minimum  contribution  of  at  least  $5,000.   Currently,  single  contribution
                                      ------
contracts are only available for use in connection  with  retirement  plans that
meet the requirements of Sections 403(b), and 408 of the Internal Revenue Code.



THE VARIABLE ACCOUNT AND THE FUNDS

     AUL will  allocate  contributions  designated  to  accumulate on a variable
basis to the Variable Account.  See the Section "Variable Account" later in this
Prospectus.  The Variable Account is currently divided into subaccounts referred
to as Investment Accounts. Each Investment Account invests exclusively in shares
of one of the portfolios of the following mutual funds:

     Each of the Funds has a different investment  objective.  A Participant may
allocate contributions to one or more of the Investment Accounts available under
a Contract.  Contributions  allocated to  a particular  Investment  Account will
increase or decrease in dollar value  depending upon the investment  performance
of the  corresponding  mutual fund  portfolio  in which the  Investment  Account
invests. These amounts are not guaranteed.  The Participant bears the investment
risk for amounts allocated to an Investment Account of the Variable Account.

FIXED ACCOUNT

     The Participant may allocate  contributions to the Fixed Account,  which is
part of AUL's  General  Account.  Amounts  allocated  to the Fixed  Account earn
interest at rates periodically  determined by AUL. These rates are guaranteed to
be at least an  effective  annual  rate of  either  3% or 4%,  depending  on the
Contract. See the Section "The Fixed Account" later in this Prospectus.

CONTRIBUTIONS


     For Recurring Contribution Contracts,  contributions may vary in amount and
frequency.  A Plan may impose maximum and minimum  contribution limits depending
on the type of Plan. In a Single Contribution  Contract,  Participants must make
contributions  of at least  $5,000.  See the  Section  "Contributions  under the
                            ------
Contracts" later in this Prospectus.



TRANSFERS

     A  Participant  may transfer his or her  Variable  Account  Value among the
Investment  Accounts or to the Fixed Account at any time during the Accumulation
Period. A Participant may transfer part of his or her Fixed Account Value to one
or more of the available  Investment  Accounts during the  Accumulation  Period,
subject  to certain  restrictions.  The  minimum  transfer  amount  from any one
Investment Account or from the Fixed Account is $500. If the Account Value in an
Investment  Account or the Fixed  Account prior to a transfer is less than $500,
then the minimum transfer amount is the Participant's remaining Account Value in
that account. If, after any transfer,  the remaining Account Value would be less
than $500,  then AUL will treat that  request as a request for a transfer of the
entire Account Value in that account. Amounts transferred from the Fixed Account
to an Investment Account during any given Contract Year cannot exceed 20% of the
Participant's  Fixed Account  Value as of the  beginning of that Contract  Year.
However, if a Participant's Fixed Account Value at the beginning of the Contract
Year is less than $2,500,  the amount that may be transferred  for that Contract
Year from the Fixed  Account is the lesser of $500 or the entire  Fixed  Account
Value as of the date the transfer request is received by AUL at its Home Office.
In certain  contracts the 20%  restriction on transfers may be waived if certain
conditions are met. For a more detailed explanation, please refer to the Section
"Transfers of Account Value" later in this Prospectus.

WITHDRAWALS


     The Participant may surrender or take a partial withdrawal from the Account
Value  at any  time  before  the  Annuity  Commencement  Date.  Withdrawals  and
surrenders  are  subject  to the  limitations  under any  applicable  Plan,  the
- ----------
Contract  and  applicable  law.  The  minimum  withdrawal  amount  from  any one
Investment Account or from the Fixed Account is $500. If the Account Value in an
Investment Account or the Fixed Account prior to a withdrawal is less than $500,
then the minimum withdrawal amount is the Participant's  remaining Account Value
in that account. If, after any withdrawal,  the remaining Account Value would be
less than $500 in that  account,  then AUL will treat that  request as a request
for a withdrawal of the entire  Account  Value in that account.  See the Section
"Cash Withdrawals" later in this Prospectus.


     Certain  retirement  programs,  such as 403(b)  Programs,  are  subject  to
constraints  on  withdrawals   and  full   surrenders.   See   "Constraints   on
Withdrawals." In addition,  distributions  under certain retirement programs may
result in a tax penalty. See the Section "Tax Penalty" later in this Prospectus.
A withdrawal  or surrender may also be subject to a withdrawal  charge.  See the
Section "Withdrawal Charge" later in this Prospectus.

THE DEATH BENEFIT


     If a Participant dies during the Accumulation  Period, AUL will pay a death
benefit to the Beneficiary.  Generally, the amount of the death benefit is equal
                             ----------
to the vested portion of the  Participant's  Account Value minus any outstanding
loan balances and any due and unpaid charges on those loans.  Some Contracts may
                                                              ------------------
contain a provision for a guaranteed minimum death benefit. A death benefit will
- -----------------------------------------------------------
not be  payable if the  Participant  dies on or after the  Annuity  Commencement
Date,  except as may be  provided  under the  Annuity  Option  elected.  See the
Sections "The Death Benefit" and "Annuity Options" later in this Prospectus.


ANNUITY OPTIONS

     The Contracts  provide for several fixed Annuity Options,  any one of which
may be elected if permitted by the applicable  Plan and applicable law. AUL will
pay fixed and  guaranteed  payments under the Annuity  Options.  See the Section
"Annuity Period" later in this Prospectus.

CHARGES

     AUL will deduct  certain  charges in  connection  with the operation of the
Contracts and the Variable Account:


     WITHDRAWAL  CHARGE  - AUL  does not  impose  a sales  charge  at the time a
contribution  is  made  to  a  Participant's  Account  under  a  Contract.  If a
Participant makes a cash withdrawal or surrenders the contract, AUL may assess a
withdrawal charge (which may also be referred to as a contingent  deferred sales
charge) where the Participant's  Account has not been in existence for a certain
period of time (see chart below).  AUL will not assess a withdrawal  charge upon
the payment of a death benefit under a Contract.  Under certain  Contracts known
as "benefit responsive" Contracts,  AUL will not impose withdrawal charges under
certain  circumstances.  See  the  Section  "Withdrawal  Charge"  later  in this
Prospectus.  Certain Recurring Contribution Contracts offered in connection with
             -------------------------------------------------------------------
403(b) Programs may have lower withdrawal charges than those shown below.

     For the first two Contract Years that a Participant's  Account exists,  AUL
will not  subject 10% of the Account  Value plus  contributions  made during the
year to withdrawal  charges.  After the first two Contract Years,  and until the
withdrawal  charge has  decreased to 0%, AUL will not subject 10% of the Account
Value to withdrawal  charges.  Certain 403(b) Contracts have Withdrawal  Charges
                               -------------------------------------------------
lower than those  shown above for  Recurring  Contribution  Contracts  but these
- --------------------------------------------------------------------------------
Contracts  do not contain  provisions  allowing  the 10% free out since they are
- --------------------------------------------------------------------------------
benefit responsive in nature.
- -----------------------------

     For some Contracts,  if a non-benefit  responsive benefit is paid causing a
     -------------------
surrender  or a  withdrawal  in excess of this 10%  allowable  amount,  AUL will
assess a  withdrawal  charge on the amount in excess of the 10%  allowable.  The
chart above  illustrates the amount of the withdrawal charge that applies to the
different  types of contracts  based on the number of years that the Account has
been in existence.  However,  the total withdrawal charge will never exceed 8.5%
                                                                            ----
of total  contributions  made by or on behalf of a Participant.  See the Section
"Withdrawal Charge" later in this Prospectus.


     PREMIUM  TAX  CHARGE - Various  states and  municipalities  impose a tax on
premiums received by insurance  companies.  AUL assesses a premium tax charge to
reimburse  itself  for  premium  taxes  that it incurs,  which  usually  will be
deducted at the time annuity  payments  commence.  Premium taxes currently range
from 0% to 3.5%, but are subject to change by such  governmental  entities.  See
the Section "Premium Tax Charge" later in this Prospectus.

     MORTALITY AND EXPENSE RISK CHARGE - AUL deducts a daily charge in an amount
equal to an  annual  rate of 1.25%  of the  average  daily  net  assets  of each
Investment  Account of the Variable Account for mortality and expense risks that
AUL assumes in connection  with the  Contracts.  Certain  contracts may elect to
have a portion  of this  charge  offset in the form of a credit of  Accumulation
Units to  Participant  Accounts,  provided  certain  conditions are met. See the
Sections  "Mortality  and Expense Risk  Charge" and  "Variable  Investment  Plus
Option" later in this Prospectus.


     ADMINISTRATIVE  CHARGE  - Under  both  Recurring  and  Single  Contribution
                                      ----             -----------
Contracts,  AUL deducts from a Participant's  Account an  administrative  charge
equal to the  lesser  of 0.5% of the  Participant's  Account  Value or $7.50 per
quarter /\ if  the  account exists  on the  quarterly Contract Anniversary.  The
        --
charge is only assessed during the Accumulation Period. An administrative charge
will not be imposed on either Recurring or Single  Contribution Contracts if the
                       ------           ---------
value  of  a  Participant's  Account  is equal to  or more  than  $25,000 on the
quarterly  Contract  Anniversary. /\  See  the Section  "Administrative  Charge"
                                  --
later in thisProspectus.


     EXPENSES OF THE FUNDS - Each  Investment  Account of the  Variable  Account
purchases shares of the  corresponding  Portfolio of one of the Funds. The price
of the shares reflect  investment  advisory fees and other expenses paid by each
Portfolio.  See the  Funds'  Prospectuses  for a  description  of these fees and
expenses.

TEN-DAY FREE LOOK

     Under  403(b)  and 408  Contracts,  the Owner  has the right to return  the
Contract for any reason within ten days of receipt.  If this right is exercised,
the  Contract  will be  considered  void from its  inception  and AUL will fully
refund any contributions.

TERMINATION BY THE OWNER

     An Owner of a Contract  acquired in  connection  with an  Employee  Benefit
Plan, a 457 Program,  or an Employer  Sponsored 403(b) Program may terminate the
Contract by sending  proper  written  notice of  termination  to AUL at its Home
Office.  Upon  termination  of such a  Contract,  the Owner  may elect  from two
payment  options.  Under one option,  AUL will assess an Investment  Liquidation
Charge (or in some  Contracts,  a Market Value  Adjustment)  on a  Participants'
Fixed Account  Withdrawal Value.  Under the second payment option,  AUL will not
assess an Investment  Liquidation  Charge or Market Value  Adjustment.  However,
amounts  attributable to the aggregate  Withdrawal Values derived from the Fixed
Account of all  Participants  under the  Contract  shall be paid in six or seven
equal annual  installments, depending on the Contract.  For more  information on
termination by an Owner,  including  information on the payment  options and the
Investment Liquidation Charge (or the Market Value Adjustment),  see the Section
"Termination by the Owner" later in this Prospectus.

                                  EXPENSE TABLE

     The purpose of the following table is to assist  investors in understanding
the various costs and expenses that  Participants in the Contracts bear directly
and indirectly.  The table reflects  expenses of the Variable Account as well as
the Funds. Expenses of the Variable Account shown under "Participant Transaction
Expenses"  (including  the  withdrawal  charge  and  annual  contract  fee)  and
"Variable  Account Annual  Expenses" are fixed and specified  under the terms of
the  Contract.  Expenses of the Funds as shown under "Fund Annual  Expenses" are
not fixed or specified under the terms of the Contract and may vary from year to
year.  The fees in this Expense  Table have been  provided by the Funds and have
not been independently verified by AUL. The table does not reflect premium taxes
that may be imposed by  various  jurisdictions.  See the  Section  "Premium  Tax
Charge" later in this Prospectus.  The information contained in the table is not
generally  applicable  to amounts  allocated to the Fixed  Account or to annuity
payments under an Annuity Option.

     For a complete description of a Contract's costs and expenses, see "Charges
and Deductions" later in this Prospectus. For a more complete description of the
Funds' costs and expenses,  see the Funds' Prospectuses.

(1) For the first two Contract Years that a Participant's  Account  exists,  for
                                                                             ---
most Recurring  Contribution  Contracts,  the amount withdrawn during a Contract
- ----------------------------------------
Year that will not be subject to an otherwise  applicable  withdrawal  charge is
10% of (a) the  total  of all  contributions  made  during  the  year  that  the
withdrawal  is being  made,  plus  (b) the  Participant's  Account  Value at the
beginning of the Contract Year.  After the first two Contract  Years,  and until
the  withdrawal  charge  has  decreased  to 0%, the  amount  withdrawn  during a
Contract  Year that will not be  subject  to a  withdrawal  charge is 10% of the
Participant's  Account  Value at the beginning of the Contract Year in which the
withdrawal is being made.  The  withdrawal  charge,  which is applied to amounts
withdrawn in excess of the 10%  allowable  amount,  decreases  from 8% to 4% for
Account years 6 through 10, and to 0% thereafter.  For certain 403(b) Contracts,
                                                   -----------------------------
the  withdrawal  charge  is 7% in  the  first  year  and  decreases  by 1%  each
- --------------------------------------------------------------------------------
subsequent year so that the withdrawal  charge reaches 0% in the eighth Contract
- --------------------------------------------------------------------------------
Year. However,  these contracts do not contain a provision allowing the 10% free
- --------------------------------------------------------------------------------
out since they are benefit  responsive  in nature.  See the Section  "Withdrawal
- --------------------------------------------------
Charge" later in this Prospectus.

(2) For the first two Contract Years that a Participant's  Account  exists,  the
amount withdrawn during a Contract Year that will not be subject to an otherwise
applicable  withdrawal charge is 10% of (a) the total of all contributions  made
during the year that the  withdrawal is being made,  plus (b) the  Participant's
Account  Value at the  beginning  of the  Contract  Year.  After  the  first two
Contract Years, and until the withdrawal  charge has decreased to 0%, the amount
withdrawn during a Contract Year that will not be subject to a withdrawal charge
is 10% of the Participant's  Account Value at the beginning of the Contract Year
in which the withdrawal is being made. The withdrawal  charge,  which is applied
to amounts withdrawn in excess of the 10% allowable  amount,  decreases by 1% in
each  subsequent  year so that the  withdrawal  charge reaches 0% in the seventh
Contract Year. See the Section "Withdrawal Charge" later in this Prospectus.

(3) The  Administrative  Charge may be less than  $30.00 per year,  based on the
/\ size of the Participant's Account. Generally, the maximum charge imposed will
- --
be the lesser of 0.5% of the Participant's Account Value or $30.00 per year.  An
administrative  charge  will  not be  imposed  on  either  Recurring  or  Single
                                                   ------             ----------
Contribution  Contracts if the value of a  Participant's  Account is equal to or
more than $25,000 on the quarterly Contract Anniversary. /\
                                                         --

(4)  This  charge  may be less  than  1.25%  for  certain  Contracts.  In  these
Contracts,  a portion of the  mortality  and expense risk charge may be credited
back to Participant's  accounts in the form of Accumulation Units. The number of
Accumulation  Units  credited will depend on the aggregate  variable  investment
account assets on deposit and the type of Contract purchased.

(5) AUL has currently agreed to waive its advisory fee if the ordinary  expenses
of a Portfolio  exceed 1% and, to the extent  necessary,  assume any expenses in
excess of its advisory fee so that the expenses of each Portfolio, including the
advisory fee but  excluding  extraordinary  expenses,  will not exceed 1% of the
Portfolio's  average  daily net asset value per year.  The Adviser may terminate
the  policy of  reducing  its fee and/or  assuming  Fund  expenses  upon 30 days
written notice to the Fund and such policy will be terminated  automatically  by
the termination of the Investment Advisory  Agreement.  During 1998, AUL reduced
its  advisory  fee for  the  Tactical  Asset  Allocation  and for the  LifeStyle
Portfolios.

     (6) American  Century VP Capital  Appreciation  fees are 1.00% on the first
$500,000,000  of  net  assets;  0.95%  on  the  next  $500,000,000;  and,  0.90%
thereafter.

     (7)  The figures above are based on expenses for fiscal year 1998, and have
been restated to reflect the  elimination of the  performance  adjustment in CVS
Mid Cap Portfolio. The restatement includes the addition of 0.01%.

     (8)  A portion of the brokerage commissions that certain funds pay was used
to reduce fund expenses. In addition, certain funds, or FMR on behalf of certain
funds,  have entered into  arrangements  with their  custodian  whereby  credits
realized as a result of uninvested  cash balances were used to reduce  custodian
expenses.  Including  these  reductions,  the total  operating  expenses,  after
reimbursement  for Index 500 Portfolio,  presented in the table would have been:
Equity-Income  Portfolio .57%; Growth Portfolio .66%;  Overseas  Portfolio .89%;
Asset  Manager  Portfolio  .63%;  Index  500  Portfolio  .28%;  and,  Contrafund
Portfolio .66%.

     (9)  All expenses are stated with contractual waivers and fee reductions by
Janus Capital. Fee reductions for the Worldwide Growth reduce the Management Fee
to the  level  of  the  corresponding  Janus  retail  fund.  Other  waivers,  if
applicable,  are first applied against the Management Fee and then against Other
Expenses.  Janus  Capital  has  agreed to  continue  the other  waivers  and fee
reductions until at least the next annual renewal of the advisory agreement.

     (10)  The Investment Adviser  agreed to  reimburse  a portion of the funds'
expenses during the period.  Without this  reimbursement,  the funds' management
fee, other  expenses and total  expenses would have been 0.85%,  0.69% and 1.54%
respectively,  for the PBHG  Growth  II  Portfolio  and  0.85%,  0.71% and 1.56%
respectively, for the PBHG Technology and Communications Portfolio.

    (11)  This is an annual all-inclusive fee paid to the advisor.

EXAMPLES (FOR ANY INVESTMENT ACCOUNT)


     The following  examples  show expenses that a Participant  would pay at the
end of one, three,  five, or ten years if at the end of those time periods,  the
Account is (1) surrendered, or (2) not surrendered.  Example (2) will also apply
to a Participant  Account that is annuitized at the end of the  applicable  time
period. The information below represents  expenses on a $1,000  contribution and
assumes a 5% return per year.  For an account that is  surrendered,  the example
shows  expenses for Recurring  Contribution  Contracts  and Single  Contribution
Contracts. Expenses will be the same for all Contracts if not surrendered. These
examples should not be considered a  representation  of past or future expenses.
Actual  expenses may be greater or less than those shown.  The assumed 5% return
is hypothetical and should not be considered a representation  of past or future
returns,  which may be greater or less than the assumed  amount.  For  Recurring
Contribution  Contracts,  the  Administrative  charge used in these  examples is
based on an estimated average Participant Account of $10,000. A pro-rata portion
of  the  annual  Administrative   Charge  has,  therefore,   been  used  in  the
calculations for Recurring  Contribution  Contracts.  The expenses for Recurring
                                                      --------------------------
Contribution  Contracts that have Withdrawal  Charges lower than 8% in the first
- --------------------------------------------------------------------------------
five years and 4% for years 6-10 would be lower than those illustrated below.

                     PERFORMANCE OF THE INVESTMENT ACCOUNTS


     The  following  tables  present  the return on  investment  for each of the
Investment  Accounts.  The return on investment  figures in the first and second
tables (including charges) represents a change in an Accumulation Unit allocated
to an Investment Account and takes into account Variable Account charges such as
the  mortality  and expense  risk  charge,  withdrawal  charges,  and a pro-rata
portion of the  administrative  charge.  The return on investment figures in the
third table  (excluding  charges) include the mortality and expense risk charge,
but do not reflect the deduction of withdrawal  charges or a pro rata portion of
the administrative  charge. For the periods that a particular Investment Account
has been in operation (see the Inception Date of Investment Account column), the
figures represent actual performance. Therefore, the performance figures for the
one year and three year  periods  ending  12/31/98  and the Lesser of 5 Years or
                                                            ------
Since Inception represent actual  performance.  For the periods that precede the
creation  of  the  Investment  Account,  if the  mutual  fund  portfolio  was in
existence  (see  Inception  Date  of  Mutual  Fund  column),  results  represent
hypothetical   returns  that  the   Investment   Accounts  that  invest  in  the
corresponding  Mutual Fund  Portfolios  would have achieved had they invested in
such Portfolios for the periods indicated.  Therefore,  the performance  figures
for  the 5 year  period  ending  12/31/98,  the  Lesser  of 10  Years  or  Since
                                                 ------
Inception,  and the  Cumulative  Returns  for the  Lesser  of 10  Years or Since
                                                   ------
Inception may be hypothetical,  or they may represent actual performance,  based
on the  inception  date of a particular  Investment  Account and the mutual fund
portfolio.

*This table  reflects a  Withdrawal  Charge of 8% in the first five years and 4%
- --------------------------------------------------------------------------------
for years 6-10.  Certain 403(b) Contracts offer lower Withdrawal  Charges (7% in
- --------------------------------------------------------------------------------
the  first  Contract  Year  declining  by 1% each  subsequent  year so that  the
- --------------------------------------------------------------------------------
Withdrawal  Charge reaches 0% in the eighth Contract Year). For these Contracts,

reincorporated  under the laws of the State of Indiana in 1933.  It is qualified
to do business in 49 states and the District of Columbia.  As a mutual  company,

     The principal  underwriter  for the  Contracts is AUL,  which is registered
with the SEC as a broker-dealer.

VARIABLE ACCOUNT

     AUL American Unit Trust was  established  by AUL on August 17, 1989,  under
procedures  established  under Indiana law. The income,  gains, or losses of the
Variable  Account are credited to or charged  against the assets of the Variable
Account  without regard to other income,  gains,  or losses of AUL. AUL owns the
assets in the Variable Account and is required to maintain  sufficient assets in
the  Variable  Account  to meet  all  Variable  Account  obligations  under  the
Contracts.   AUL  may  transfer  to  its  General  Account  assets  that  exceed
anticipated  obligations of the Variable Account.  All obligations arising under
the Contracts are general  corporate  obligations of AUL. AUL may invest its own
assets in the Variable  Account,  and may  accumulate  in the  Variable  Account
proceeds  from  Contract  charges and  investment  results  applicable  to those
assets.

     The Variable Account is currently divided into sub-accounts  referred to as
Investment Accounts.  Each Investment Account invests exclusively in shares of a
specific  mutual  fund  or  in  a  specific  Portfolio  of  one  of  the  Funds.
Contributions  may be allocated  to one or more  Investment  Accounts  available
under a Contract.  Not all of the Investment  Accounts may be available  under a
particular  Contract and some of the  Investment  Accounts are not available for
certain  types  of  Contracts.  AUL  may  in  the  future  establish  additional
Investment  Accounts  of  the  Variable  Account,  which  may  invest  in  other
Portfolios  of the Funds or in other  securities,  mutual  funds,  or investment
vehicles.

     The Variable  Account is registered with the SEC as a unit investment trust
under the Investment Company Act of 1940 (the "1940 Act"). Registration with the
SEC does not involve  supervision by the SEC of the administration or investment
practices of the Variable Account or of AUL.

commonly  referred to as a mutual fund. Each of the Funds is registered with the

SEC of the  investments  or  investment  policies or practices of the Fund.  AUL

the  Portfolio's  net asset value per share,  i.e.,  without any sales load. All
dividends  and  capital  gain  distributions   received  from  a  Portfolio  are

                                 THE CONTRACTS

GENERAL

     The Contracts are offered for use in connection with retirement  plans that
meet the  requirements  of Sections  401,  403(b),  408, or 457 of the  Internal
Revenue  Code.  Certain  Federal  tax  advantages  are  currently  available  to
retirement plans that qualify as (1) self-employed individuals' retirement plans
under  Section 401,  such as HR-10 Plans,  (2) pension or  profit-sharing  plans
established  by an Employer for the benefit of its employees  under Section 401,
(3) annuity  purchase plans  sponsored by certain  tax-exempt  organizations  or
public school  organizations  under Section  403(b),  (4) individual  retirement
accounts  or  annuities,  including  those  established  by  an  employer  as  a
simplified  employee  pension plan or SIMPLE IRA plan, under Section 408, or (5)
deferred  compensation  plans for employees  established by a unit of a state or
local  government  or by a  tax-exempt  organization  under  Section  457.  Some
Contracts may also be made  available to plans that do not qualify for favorable
tax  treatment,   such  as  unfunded  deferred  compensation  Plans  for  highly
compensated employees, which may be referred to as non-qualified 457 Plans.

     A  Contract  is  issued  to  the  Owner.  Generally,  persons  eligible  to
participate  in the Owner's Plan are eligible to become  Participants  under the
Contract.  The  Owner  shall be  responsible  for  determining  persons  who are
eligible to become  Participants  and for  designating  such persons to AUL. AUL
will  issue to the  Owner  for  delivery  to each  Participant  (or may  deliver
directly to each  Participant) a Certificate  that  evidences the  Participant's
participation  in the Contract.  For purposes of  determining  benefits  under a
Contract,  an account called a  Participant's  Account is  established  for each
Participant during the Accumulation Period.

     The Owner of the  Contract  is  generally  responsible  for  providing  all
communications and instructions concerning Participant Accounts to AUL. However,
in some instances a Participant may communicate  directly with AUL. For example,
a Participant in a 403(b) Program may request a partial withdrawal directly from
AUL. While the Owner generally is responsible for transmitting contributions and
instructions for  Participants,  the Participant may be permitted or required to
make certain  decisions  and elections  under the Contract,  as specified by the
Owner in the Plan,  trust,  or other  appropriate  document.  The pertinent Plan
document  and,  if  applicable,  the  Employer's  plan  administrator  should be
consulted with any questions on benefits under the Contract.


        CONTRIBUTIONS AND CONTRACT VALUES DURING THE ACCUMULATION PERIOD

CONTRIBUTIONS UNDER THE CONTRACTS


     Contributions under Recurring  Contribution  Contracts may be made by or on
behalf of a Participant at any time during the Participant's life and before the
Participant's Annuity Commencement Date. Contributions must be at least equal to
the  minimum  required  contribution  under  the Plan.  In  Single  Contribution
Contracts,  the minimum  contribution  for each  Participant is $5,000.  AUL may
                                                                ------
establish the minimum  contributions  permitted  under a Contract,  but any such
change  shall apply only to  Participant  Accounts  established  on or after the
effective  date of the  change.  AUL may, at its  discretion,  waive any minimum
required contribution.


     Annual  contributions  under any of the Plans are subject to maximum limits
imposed  by  the  Internal   Revenue  Code.  See  the  Statement  of  Additional
Information  for a discussion  of these limits,  or consult the  pertinent  Plan
document.

TEN-DAY FREE LOOK

     Under  403(b)  and 408  Contracts,  the Owner  has the right to return  the
Contract  for any  reason  within ten days of  receipt.  If a  particular  state
requires a longer  free-look  period,  Owners in that state will be allowed  the
longer  statutory  period  in which to return  the  Contract.  If this  right is
exercised,  the Contract will be  considered  void from its  inception,  and any
contributions will be fully refunded.

INITIAL AND SINGLE CONTRIBUTIONS

     Initial  contributions  received for a Participant  will be credited to the
Participant's  Account no later than the end of the second Business Day after it
is received by AUL at its Home  Office if it is  preceded  or  accompanied  by a
completed  annuity  enrollment  form for the  Participant  that contains all the
information necessary for opening the Participant's Account. The enrollment form
will be provided by AUL. If AUL does not receive a complete  enrollment form for
a  Participant,  AUL  will  notify  the  individual  that  AUL does not have the
necessary  information to open the account. If the necessary  information is not
provided to AUL within five Business  Days after AUL first  receives the initial
contribution,  AUL will  return the  initial  contribution  to the  contributing
party.  However, if the Contract so allows, AUL may retain the contribution,  if
consent is received, until the earliest of: the time the enrollment form for the
Participant is made complete, or 25 days after receipt at AUL's Home Office.

ALLOCATION OF CONTRIBUTIONS


     Initial and subsequent  contributions under the Contracts will be allocated
among the Investment  Accounts of the Variable  Account and the Fixed Account as
instructed  by the  Owner or  Participant  and as  provided  by the terms of the
Contract.  The  investment  allocation  of  the  initial  contribution  is to be
designated on an investment  allocation form at the time the annuity  enrollment
form is  completed,  and the  completed  allocation  form should  accompany  the
enrollment  form to open an account for a Participant.  Depending on the type of
Contract,  the  enrollment  application  specifies  that  in the  absence  of an
investment  allocation  form  or  other  instructions,  initial  and  subsequent
contributions  shall be allocated to the AUL  American  Money Market  Investment

been initially allocated to  the Money Market Investment  Account or to /\ AUL's
                                                                        --
General  Account may be transferred  to other available  investment options upon
receipt by  AUL at its  Home Office of an  investment  allocation  form or other
proper request.  Under some  Contracts,  allocation  to any  Investment  Account
or the Fixed Account  must be made in  increments of 10%, 25%, or 33 1/3% of any
contribution.  Neither the Fixed Account nor all of the Investment  Accounts may
be available under a particular  Contract. In addition,  some of the  Investment
Accounts are not available for certain types of Contracts.


     Any change in allocation instructions will be effective upon receipt by AUL
at its Home  Office and will  continue  in effect  until  subsequently  changed.
Changes  in the  allocation  of future  contributions  have no effect on amounts
already contributed on behalf of a Participant.  Such amounts,  however,  may be
transferred  among the Investment  Accounts of the Variable Account or the Fixed
Account in the manner described in "Transfers of Account Value."

SUBSEQUENT CONTRIBUTIONS UNDER RECURRING CONTRIBUTION CONTRACTS

     When  forwarding  contributions  to AUL,  the amount being  contributed  on
behalf  of each  Participant  must be  specified.  The  contributions  shall  be
allocated  among  the  Investment  Accounts  of the  Variable  Account  that are
available  under a Contract and the Fixed  Account (if  available)  as described
above in "Allocation of  Contributions."  Contributions  (other than the initial
contribution  for each  Participant) are credited as of the end of the Valuation
Period in which they are  received by AUL at its Home Office at such time as AUL
has  received  full  payment for the  contribution,  the  information  needed to
establish  the  Participant's  account,  and proper  instructions  regarding the
application and allocation of the contributions among Participants.

TRANSFERS OF ACCOUNT VALUE

     All or part of a  Participant's  Variable  Account Value may be transferred
among the Investment Accounts of the Variable Account that are available under a
Contract or to the Fixed  Account (if  available  under a Contract)  at any time
during the  Accumulation  Period upon receipt of a proper written request by AUL
at  its  Home  Office.  Transfers  may  be  made  by  telephone  if a  Telephone
Authorization  Form has been properly  completed and received by AUL at its Home
Office.  The  minimum  transfer  from any  Investment  Account or from the Fixed
Account is the lesser of $500 or a  Participant's  entire  Account Value in that
Investment  Account or in the Fixed Account as of the date the transfer  request
is  received  by  AUL  at  its  Home  Office,  provided  however,  that  amounts
transferred  from the Fixed  Account to an Investment  Account  during any given
Contract Year cannot exceed 20% of the  Participant's  Fixed Account Value as of
the beginning of that Contract Year.  However,  if a Participant's Fixed Account
Value at the beginning of the Contract Year is less than $2,500, the amount that
will be transferred  for that Contract Year from the Fixed Account is the lesser
of $500 or the entire Fixed Account Value as of the date the transfer request is
received by AUL at its Home Office.  If, after any transfer,  the  Participant's
remaining  Account Value in an Investment  Account or in the Fixed Account would
be less than $500, then such request will be treated as a request for a transfer
of the entire Account Value.  Transfers may also be subject to other limitations
provided  in a Plan  document  and in  the  Contract.  The  20%  restriction  on
transfers during any given Contract Year from the Fixed Account to an Investment
Account shall not apply to Employer Sponsored 403(b) Programs,  Employee Benefit
Plans,  Employee  Benefit Plans in a combined  Contract for an Employee  Benefit
Plan and Employer  Sponsored 403(b) Plan, or 408 SEP or SIMPLE IRA Contracts if:
(1) the  Owner  (or Plan  Sponsor)  selects  the Fixed  Interest  Account  as an
Investment  Option to  Participants  under the Contract;  (2) the Owner (or Plan
Sponsor) does not select the AUL American Money Market Investment  Account as an
available  Investment  Option  to  Participants  under  the  Contract,  and  (3)
following  a  transfer  from the Fixed  Account  to the  Variable  Account  by a
Participant, a transfer back to the Fixed Account shall be allowed only after 90
days have elapsed since the previous transfer from the Fixed Account.  Except as
noted previously, generally, there are no limitations on the number of transfers
between Investment  Accounts available under a Contract or the Fixed Account. In
addition,  no charges are  currently  imposed upon  transfers.  AUL reserves the
right,  however,  at a future  date,  to change the  limitation  on the  minimum
transfer, to assess transfer charges, to change the limit on remaining balances,
to limit the number and  frequency  of  transfers,  and to suspend the  transfer
privilege  or  the  telephone  transfer  authorization.  Any  transfer  from  an
Investment  Account of the Variable  Account shall be effective as of the end of
the Valuation Date in which AUL receives the request in proper form.

PARTICIPANT'S VARIABLE ACCOUNT VALUE

ACCUMULATION UNITS

     Contributions to be allocated to the Investment  Accounts available under a
Contract  will  be  credited  to  the  Participant's  Account  in  the  form  of
Accumulation   Units.   Except  for  allocation  of  a   Participant's   initial
contribution,  the number of Accumulation  Units to be credited is determined by
dividing the dollar amount allocated to the particular Investment Account by the
Accumulation Unit value for the particular  Investment Account at the end of the
Valuation  Period  in which  the  contribution  is  received  by AUL at its Home
Office. The number of Accumulation Units so credited to the account shall not be
changed by a subsequent  change in the value of an  Accumulation  Unit,  but the
dollar value of an  Accumulation  Unit may vary from Valuation Date to Valuation
Date  depending upon the  investment  experience of the  Investment  Account and
charges against the Investment Account.

ACCUMULATION UNIT VALUE

     AUL determines the Accumulation  Unit value for each Investment  Account of
the Variable  Account on each Valuation  Date. The  Accumulation  Unit value for
each  Investment  Account was initially  set at one dollar ($1) when  operations
commenced. Subsequently, the Accumulation

<PAGE>
                                       23

Unit value for each  Investment  Account is  determined by  multiplying  the Net
Investment Factor for the particular Investment Account by the Accumulation Unit
value for the  Investment  Account  as of the  immediately  preceding  Valuation
Period.  The Accumulation  Unit value for each Investment  Account may increase,
decrease,  or remain  the same from  Valuation  Period  to  Valuation  Period in
accordance with the Net Investment Factor.

NET INVESTMENT FACTOR

     The Net Investment Factor is used to measure the investment  performance of
an Investment  Account from one Valuation Period to the next. For any Investment
Account for a Valuation  Period,  the Net  Investment  Factor is  determined  by
dividing (a) by (b) and then subtracting (c) from the result where

   (a) is equal to:
      (1) the net asset  value per share of the  Portfolio  of the Fund in which
          the  Investment  Account  invests,  determined  as of  the  end of the
          Valuation Period, plus
      (2) the per share  amount of any dividend or other  distribution,  if any,
          paid by the Portfolio during the Valuation Period, plus or minus
      (3) a credit or charge with respect to taxes paid, if any, or reserved for
          by AUL during the  Valuation  Period that are  determined by AUL to be
          attributable to the operation of the Investment  Account  (although no
          Federal income taxes are applicable under present law and no such
          charge is currently assessed).
      (b) is the net asset value per share of the Portfolio,  determined  as  of
          the end of the preceding Valuation Period; and
      (c) is a daily charge factor determined by AUL to reflect the fee assessed
          against  the assets  of the  Investment  Account for the mortality and
          expense risk charge.


DOLLAR COST AVERAGING PROGRAM

     Contract  Owners  and  Participants  who  wish  to  purchase  units  of  an
Investment  Account  over a period of time may do so  through  the  Dollar  Cost
Averaging  ("DCA") Program.  The theory of dollar cost averaging is that greater
numbers of  Accumulation  Units are  purchased at times when the unit prices are
relatively  low than are  purchased  when the  prices are  higher.  This has the
effect,  when purchases are made at different  prices, of reducing the aggregate
average cost per Accumulation  Unit to less than the average of the Accumulation
Unit prices on the same purchase  dates.  However,  participation  in the Dollar
Cost  Averaging  Program  does not assure a  Contract  Owner or  Participant  of
greater  profits from the  purchases  under the Program,  nor will it prevent or
necessarily alleviate losses in a declining market.

     For example,  assume that a Contract  Owner or  Participant  requests  that
$1,000 per month be transferred from the Money Market Investment  Account to the
AUL American Equity  Investment  Account.  The following  Table  illustrates the
effect of dollar cost averaging over a six month period.


                  Transfer                  Unit              Units
        Month      Amount                   Value            Purchased
        -----     --------                  -----            ---------
         1        $1,000                    $20               50
         2        $1,000                    $25               40
         3        $1,000                    $30               33.333
         4        $1,000                    $40               25
         5        $1,000                    $35               28.571
         6        $1,000                    $30               33.333


     The  average  price per unit for these  purchases  is the sum of the prices
($180)  divided by the number of monthly  transfers (6) or $30. The average cost
per  Accumulation  Unit for  these  purchases  is the total  amount  transferred
($6,000) divided by the total number of Accumulation  Units purchased  (210.237)
or  $28.54.   THIS  TABLE  IS  FOR   ILLUSTRATIVE   PURPOSES  ONLY  AND  IS  NOT
REPRESENTATIVE OF FUTURE RESULTS.

     Under a DCA  Program,  the owner  deposits  premiums  into the AUL American
Money Market  Investment  Account or the Fixed Account (if  available  under the
Contract)  and then  authorizes  AUL to transfer a specific  dollar amount for a
specific  length of time from such  Account  into one or more  other  Investment
Accounts at the unit values  determined on the dates of the transfers.  This may
be done monthly, quarterly,  semi-annually, or annually on the last business day
of such period.  These transfers will continue  automatically until the earliest
of: the date AUL receives notice to discontinue the Program;  until there is not
enough  money in the Money  Market  Investment  Account or the Fixed  Account to
continue the Program; until the expiration of the length of time selected; or if
the transfers are being drawn from the Fixed Account,  until the time a transfer
would exceed the 20% limitation on transfers from the Fixed Account.

     Currently,  the minimum required amount of each transfer is $100,  although
AUL reserves the right to change this minimum transfer amount in the future. DCA
transfers to the Fixed  Account and to the Money Market  Investment  Account are
not permitted under the Dollar Cost Averaging Program. At least ten days advance
written notice to AUL is required before the date of the first proposed transfer
under the DCA Program.  AUL offers the Dollar Cost Averaging Program to Contract
Owners and  Participants  at no charge,  and the Company  reserves  the right to
temporarily discontinue,  terminate, or change the Program at any time. Contract
Owners and Participants may discontinue participation in the Program at any time
by providing  written  notice to AUL,  provided  that AUL must  receive  written
notice  of such a change  at least  five  days  before  a  previously  scheduled
transfer is to occur.

     Contract Owners or  Participants  may initially elect to participate in the
DCA  Program,  and if this  election is made at the time the Contract is applied
for, the Program will take effect on the first monthly, quarterly,  semi-annual,
or annual transfer date following the premium receipt by AUL at its Home Office.
The Contract Owner or Participant  may select the month,  quarter,  or year that
the transfers are to be made and such transfers will  automatically be performed
on the last  business  day of such period.  To  participate  in the  Program,  a
minimum  balance  of $10,000 in the Money  Market  Investment  Account or in the
Fixed Account is required.

                  CASH WITHDRAWALS AND THE DEATH BENEFIT

CASH WITHDRAWALS

     During the  lifetime  of the  Participant,  at any time  before the Annuity
Commencement  Date and subject to the limitations  under the applicable Plan and
applicable  law,  a  Participant's  Account  may  be  surrendered  or a  partial
withdrawal  may be taken from a  Participant's  Account  Value.  A surrender  or
withdrawal  request will be effective as of the end of the Valuation Date that a
proper  written  request in a form  acceptable  to AUL is received by AUL at its
Home Office.

     A full surrender of a Participant's Variable Account Value will result in a
withdrawal  payment  equal to the value of the  Participant's  Variable  Account
Value as of the end of the  Valuation  Period  during which a proper  withdrawal
request is received by AUL at its Home Office,  minus any applicable  withdrawal
charge.  A partial  withdrawal  may be requested  for a specified  percentage or
dollar amount of a Participant's Variable Account Value. A request for a partial
withdrawal will result in a payment by AUL equal to the amount  specified in the
partial withdrawal  request.  Upon payment,  the Participant's  Variable Account
Value will be  reduced  by an amount  equal to the  payment  and any  applicable
withdrawal  charge.  If a partial  withdrawal  is  requested  that would leave a
Participant's  Variable Account Value in any Investment  Account less than $500,
then such  partial  withdrawal  request  will be treated as a request for a full
withdrawal from the Investment Account.

     The minimum  amount that may be  withdrawn  from a  Participant's  Variable
Account  Value  in  an  Investment   Account  is  the  lesser  of  $500  or  the
Participant's  entire Account Value in the Investment Account as of the date the
withdrawal  request is received by AUL.  However,  if after the withdrawal,  the
amount or value of the  Investment  Account  would be less than  $500,  then the
request  will be treated as a request  for a  withdrawal  of the entire  Account
Value of the Investment Account.

     The  amount  of a  partial  withdrawal  will be taken  from the  Investment
Accounts and the Fixed Account as instructed.  A partial  withdrawal will not be
effected until proper instructions are received by AUL at its Home Office.

     A  surrender  or a partial  withdrawal  may  result in the  deduction  of a
withdrawal charge. See "Withdrawal Charge."

     In addition,  distributions under certain retirement programs may result in
a tax penalty. See "Tax Penalty."

SYSTEMATIC WITHDRAWAL SERVICE FOR 403(b) AND 408 PROGRAMS


     A Participant  in a Contract  used in connection  with a 403(b) plan (other
than an Employer  Sponsored  403(b)  plan) or 408 Program who is at least age 59
1/2 can generally  arrange to have systematic cash  withdrawals  from his or her
        ---------
Account  Value  paid on a regular  monthly,  quarterly,  or annual  basis.  Each
withdrawal  payment  must  be at  least  equal  to  $100.  An  application  form
containing  details of the  service is  available  upon  request  from AUL.  The
service is voluntary  and can be terminated  at any time by the  Participant  or
Owner. AUL does not currently  deduct a service charge for withdrawal  payments,
but reserves the right to do so in the future and similarly,  reserves the right
to increase the minimum required amount for each withdrawal payment.  Systematic
                                                                      ----------
withdrawals are not available for some 403(b) Contracts with reduced  withdrawal
- --------------------------------------------------------------------------------
charges due to the benefit responsive features of the Contracts.
- ----------------------------------------------------------------

     Participants will pay a withdrawal charge in connection with the systematic
cash withdrawals to the extent the withdrawal charge is applicable. /\ Depending
                                                                    ------------
on the Contract, some  Recurring Contribution  Contracts  will incur  withdrawal
- -----------------------                                   ----------------------
charges  during the first ten Account  Years or the first seven  Account  Years,
- -------                                      -----------------------------------
excluding the 10% allowable  amount each Contract Year (if the Contract  permits
the 10% allowable amount).  If the Contract  so permits,  Systematic withdrawals
                            ----------------------------
of up to 10% of (a) the total of all contributions made during the year that the
withdrawal  is being  made,  plus  (b) the  Participant's  Account  Value at the
beginning of the Contract Year may begin in the year the  Participant's  Account
is  established.  After the first two Contract  Years,  and until the withdrawal
charge has  decreased to 0%, the amount  withdrawn  during a Contract  Year that
will not be subject to a withdrawal charge is 10% of the  Participant's  Account
Value at the  beginning of the Contract  Year in which the  withdrawal  is being
made. See "Withdrawal Charge." In addition,  receipt of the cash withdrawals may
result in the receipt of taxable  income to the  Participant.  See  "Federal Tax
Matters." No withdrawal  charges are applied to "benefit  responsive"  Contracts
for  payment  of  retirement,  death,  disability,  termination  of  employment,
hardship,  loan, age 70 1/2 required minimum  distribution  benefits or benefits
upon attainment of age 59 1/2 (provided that the age 59 1/2 benefit is a taxable
distribution  paid to the  Participant  and not to any other  person or  entity,
including any  alternative  or  substitute  funding  medium).  For certain other
Contracts known as "modified benefit responsive"  Contracts,  withdrawal charges
are not  imposed for cash  lump-sum  payments of death  benefits.  For  Modified
Benefit  Responsive  Contracts,  withdrawal  charges  are not  imposed  for cash
lump-sum  payments  provided the  Participant has (1) attained age 55 and has 10
years of service with the employer  identified  in the Plan, or (2) attained age
62,  and is  receiving  benefits  for  retirement,  disability,  termination  of
employment, hardships, loans, or required minimum distribution benefits pursuant
to Internal Revenue Code Section 401(a)(9) and Regulations issued thereunder, or
for benefits  upon  attainment  of age 59 1/2  (provided  that such benefit upon
attainment of age 59 1/2 is a taxable  distribution  paid to the Participant and
not to any other  person or entity,  including  any  alternative  or  substitute
funding medium).


     However,   even  in  benefit  responsive  or  modified  benefit  responsive
contracts,  withdrawal  charges will be applied to any  withdrawal to pay a Plan
benefit prior to notification of Contract  termination if the benefit is payable
because of, or the underlying  reason for payment of the benefit results in, the
termination or partial  termination of the Plan, as determined  under applicable
IRS guidelines.


CONSTRAINTS ON WITHDRAWALS

GENERAL

     Since the Contracts offered by this Prospectus will be issued in connection
with retirement plans that meet the
<PAGE>
                                       25


requirements of Section 401, Section 403(b),  Section 408, or Section 457 of the
Internal  Revenue Code,  reference should be made to the terms of the particular
Plan or Contract for any  limitations or  restrictions  on cash  withdrawals.  A
surrender or withdrawal that results in receipt of proceeds by a Participant may
result in receipt of taxable income to the  Participant  and, in some instances,
in a tax penalty.  The tax  consequences of a surrender or withdrawal  under the
Contracts should be carefully considered. See "Federal Tax Matters."


403(b) PROGRAMS

     Section 403(b) of the Internal Revenue Code permits public school employees
and  employees  of certain  types of  charitable,  educational,  and  scientific
organizations  specified in Section  501(c)(3)  of the Internal  Revenue Code to
purchase annuity contracts, and, subject to certain limitations,  to exclude the
amount of purchase payments from gross income for federal tax purposes.  Section
403(b) imposes restrictions on certain  distributions from tax-sheltered annuity
contracts  meeting the  requirements  of Section  403(b) that apply to tax years
beginning on or after January 1, 1989.

     Section   403(b)   requires   that   distributions   from  Section   403(b)
tax-sheltered  annuities that are  attributable to employee  contributions  made
after December 31, 1988 under a salary reduction  agreement not begin before the
employee reaches age 59 1/2, separates from service,  dies, becomes disabled, or
incurs a hardship. Furthermore, distributions of income or gains attributable to
such contributions accrued after December 31, 1988 may not be made on account of
hardship.  Hardship,  for this purpose, is generally defined as an immediate and
heavy  financial need,  such as paying for medical  expenses,  the purchase of a
principal residence, or paying certain tuition expenses.

     A Participant  in a Contract  purchased as a  tax-deferred  Section  403(b)
annuity  contract  will not,  therefore,  be entitled  to exercise  the right of
surrender or withdrawal,  as described in this  Prospectus,  in order to receive
his or her  Account  Value  attributable  to  contributions  made under a salary
reduction  agreement or any income or gains credited to such  Participant  after
December  31,  1988  under  the  Contract  unless  one  of  the  above-described
conditions has been satisfied,  or unless the withdrawal is otherwise  permitted
under  applicable  federal  tax  law.  In  the  case  of  transfers  of  amounts
accumulated  in a different  Section  403(b)  contract to this Contract  under a
Section 403(b)  Program,  the withdrawal  constraints  described above would not
apply to the amount transferred to the Contract  attributable to a Participant's
December 31, 1988 account  balance  under the old  contract,  provided  that the
amounts transferred between contracts qualifies as a tax-free exchange under the
Internal Revenue Code. A Participant's  Account  Withdrawal in a Contract may be
able to be  transferred  to certain other  investment  alternatives  meeting the
requirements  of Section 403(b) that are available  under an Employer's  Section
403(b) arrangement.

TEXAS OPTIONAL RETIREMENT PROGRAM

     AUL  intends to offer the  Contract  within the Texas  Optional  Retirement
Program.  Under  the  terms  of the  Texas  Optional  Retirement  Program,  if a
Participant makes the required contribution,  the State of Texas will contribute
a specified  amount to the  Participant's  Account.  If a  Participant  does not
commence the second year of participation in the plan as a "faculty  member," as
defined  in Title  110B of the  State of Texas  Statutes,  AUL will  return  the
State's   contribution.   If  a   Participant   does  begin  a  second  year  of
participation, the Employer's first-year contributions will then be applied as a
contribution   under   the   Contract,   as  will  the   Employer's   subsequent
contributions.

     The Attorney  General of the State of Texas has ruled that under Title 110B
of the State of Texas Statutes,  withdrawal  benefits of contracts  issued under
the  Optional   Retirement  Program  are  available  only  in  the  event  of  a
participant's  death,  retirement,   termination  of  employment  due  to  total
disability,  or other termination of employment in a Texas public institution of
higher  education.  A Participant under a Contract issued in connection with the
Texas Optional Retirement Program will not,  therefore,  be entitled to exercise
the right of surrender or withdrawal  to receive the Account  Value  credited to
such Participant unless one of the foregoing conditions has been satisfied.  The
Withdrawal Value of such Participant's  Account may, however,  be transferred to
other  contracts or other  carriers  during the period of  participation  in the
program.

THE DEATH BENEFIT

     If a Participant dies during the Accumulation  Period, AUL will pay a death
benefit to the Beneficiary upon receipt of due proof of the Participant's  death
and instructions regarding payment to the Beneficiary. If there is no designated
Beneficiary  living  on the date of death of the  Participant,  AUL will pay the
death  benefit in one sum to the estate of the  Participant  upon receipt of due
proof of  death  of both the  Participant  and the  designated  Beneficiary  and
instructions  regarding  payment.  If the death of the Participant  occurs on or
after the Annuity  Commencement Date, no death benefit will be payable under the
Contract except as may be provided under the Annuity Option elected.


     The  amount  of  the  death  benefit  equals  the  vested  portion  of  the
Participant's  Account Value minus any outstanding loan balances and any due and
unpaid charges on those loans.  Under Contracts  acquired in connection with 408
Programs, 457 Programs, and 403(b) Programs other than Employer Sponsored 403(b)
Programs,  the vested  portion of a  Participant's  Account  Value  shall be the
Participant's  entire Account Value.  Under Employee  Benefit Plans and Employer
Sponsored 403(b) Programs,  the vested portion of a Participant's  Account Value
is the amount to which the Participant is entitled upon death or separation from
service under a vesting  schedule  contained in the pertinent Plan. If the death
benefit is less than a Participant's  Account Value,  the death benefit shall be
paid pro rata  from the  Investment  Accounts  and the  Fixed  Account,  and the
remainder of the Account Value shall be  distributed to the Owner or as directed
by the Owner.  Prior to such  distribution,  any remaining  Account Value in the
Investment  Accounts  shall be  transferred  to AUL's General  Account or if the
                                                                       ---------
Contract so directs, to the AUL American Money Market Investment Account. In the
- -------------------------------------------------------------------------
case of  457  Program,  the  Owner  of the  Contract  shall be the  Beneficiary.
Certain   Contracts   have   a  death  benefit  which  is  the   greater  of the
- --------------------------------------------------------------------------------
Participant's  Account Value as of the date the death benefit is calculated or a
- --------------------------------------------------------------------------------
Guaranteed  Minimum   Death   Benefit  ("GMDB")  on  the  Contract  Anniversary

contributions  made  for the Participant since the last Contract Anniversary and
- --------------------------------------------------------------------------------
reduced proportionately to reflect any withdrawals for the Participant since the
- --------------------------------------------------------------------------------
last Contract Anniversary).  Prior  to  the  first  Contract  Anniversary,   the
- --------------------------------------------------------------------------------
Guaranteed Minimum Death Benefit equals the contributions made for a Participant
- --------------------------------------------------------------------------------
less  any  withdrawals  or  loans.   On  each  Contract Anniversary prior to, or
- --------------------------------------------------------------------------------
concurrent  with, the  Participant's date of death, the Guaranteed Minimum Death
- --------------------------------------------------------------------------------
Benefit  is  reset,  based  on the  age of the  Participant  on his or  her last
- --------------------------------------------------------------------------------
birthday,  as follows: for Participants  less than 81 years of age,  the GMDB is
- --------------------------------------------------------------------------------
the  greater of (1) the Participant's  Account  Value as of the current Contract
- --------------------------------------------------------------------------------
Anniversary or (2) the GMDB as of the most recent Contract Anniversary  plus any
- --------------------------------------------------------------------------------
contributions  made for the Participant since the preceding Contract Anniversary
- --------------------------------------------------------------------------------
and  reduced  proportionately  by any  withdrawals for the Participant since the
- --------------------------------------------------------------------------------
most recent Contract Anniversary.  For Participants  who have reached their 81st
- --------------------------------------------------------------------------------
birthday,  the  GMDB  is  equal  to  the  GMDB  as  of  the  preceding  Contract
- --------------------------------------------------------------------------------
Anniversary,  increased  by  contributions  made for  the Participant  since the
- --------------------------------------------------------------------------------
preceding  Contract  Anniversary  and reduced proportionately by any withdrawals
- --------------------------------------------------------------------------------
for  the  Participant  since  the  most  recent Contract Anniversary.  As of the
- --------------------------------------------------------------------------------
Participant's death, the GMDB ceases to increase or decrease in value.

     The death benefit (or the Guaranteed  Minimum Death Benefit if the Contract
                       ---------------------------------------------------------
so provides) will be paid to the Beneficiary in a single sum or under one of the
- ------------
Annuity  Options,   as  directed  by  the  Participant  or  as  elected  by  the
Beneficiary.  If the Beneficiary is to receive annuity payments under an Annuity
Option,  there may be limits under  applicable law on the amount and duration of
payments that the Beneficiary may receive, and requirements respecting timing of
payments. A tax adviser should be consulted in considering payout options.


TERMINATION BY THE OWNER

     An Owner of a Contract  acquired in  connection  with an  Employee  Benefit
Plan, a 457 Program,  or an Employer  Sponsored 403(b) Program may terminate the
Contract by sending  proper  written  notice of  termination  to AUL at its Home
Office.  Termination shall be effective as of the end of the Valuation Date that
the notice is received by AUL at its Home Office.  Proper notice of  termination
must  include an  election  of the method of payment or  payments  from AUL,  an
indication  of the  person or persons  to whom  payment  is to be made,  and the
Owner's agreement (and the Plan Sponsor's  agreement,  if the Contract is issued
in  connection  with an Employee  Benefit Plan or an Employer  Sponsored  403(b)
Program)  that AUL shall not be held  responsible  for any losses or claims that
may arise  against AUL in  connection  with  making a payment or  payments  upon
termination.


     Upon  termination  of such a Contract used in  connection  with an Employee
Benefit  Plan,  a 457  Program,  or Employee  Benefit  Plan  contributions  in a
combined  Contract for an Employee  Benefit Plan and Employer  Sponsored  403(b)
Plan,  the Owner (and the Plan Sponsor,  if the Contract is issued in connection
with an Employee  Benefit  Plan) may elect from two payment  options.  Under one
option,  AUL will pay an amount equal to the aggregate  Withdrawal Values of all
of the Participant  Accounts under the Contract  determined as of the end of the
Valuation  Date  that  the  termination  is  effective,   minus  any  applicable
Investment Liquidation Charge  ("ILC") /\ or  plus or  minus  any  Market  Value
                                       --
Adjustment ("MVA") /\ depending on the Contract.  The ILC or MVA applies only to
                   -----------------------------
Participants'  Fixed  Account  Values under these  Contracts.  The ILC or MVA is
equal to a certain percentage,  as described below, multiplied by the Withdrawal
Value derived from the Fixed Account of each Participant  under a Contract.  The
ILC  percentage is determined by the following  formula:  6(x - y), where "x" is
the Current Rate of interest,  as described under  "Interest," being credited by
AUL to new Contributions allocated to the Fixed Account as of the effective date
of termination, and "y" is the average rate of interest being credited by AUL to
various portions of a Participant's Fixed Account Value as of the effective date
of termination.  The MVA percentage is determined by the following formula: When
"x" is greater than "y", the MVA percentage is 5(x-y),  and is deducted from the
amount paid. When "y" is greater than "x", the MVA percentage is 4(x-y),  and is
added to the amount paid.  Payment  under this option shall be made as described
under  "Payments  from the  Variable  Account,"  except that  payment of amounts
attributable  to the Fixed Account may be delayed for up to six months after the
effective date of termination.


     Under the second payment option for a 457 Program Contract, AUL will pay an
amount  equal to the  aggregate  Withdrawal  Values  derived  from the  Variable
Account of all Participants  under the Contract  determined as of the end of the
Valuation Date on which  termination is effective.  Payment of this amount shall
be made as described under  "Payments from the Variable  Account." AUL will also
pay an amount equal to the aggregate  Withdrawal  Values  derived from the Fixed
Account of all  Participants  under the Contract as of the Contract  Anniversary
immediately  succeeding the effective date of termination.  This amount shall be
payable in six equal  annual  installments,  the first of which shall be paid on
the  Contract   Anniversary   immediately   succeeding  the  effective  date  of
termination.  As of this  date,  AUL  shall  have the  right to refuse to accept
further  contributions  and  shall  cease  to  maintain  individual  Participant
Accounts, and amounts remaining under the Contract after each annual installment
shall be paid interest by AUL at an annual effective rate that shall be equal to
the lesser of (a) the weighted  average of each of the various  Current Rates of
interest  being credited to amounts held in the Fixed Account under the Contract
determined as of the Contract Anniversary  immediately  succeeding the effective
date of  termination,  or (b) the  interest  rate for U.S.  Government  Security
Treasury  Constant Maturity for three years (as set forth in the Federal Reserve
Statistical Releases), as determined on the Business Day coincident with or next
following the Contract Anniversary  immediately succeeding the effective date of
termination.  Interest earned during the Contract Year following  payment of any
annual  installment  shall  be  paid  by  AUL on the  next  succeeding  Contract
Anniversary.


     Under the second payment option for an Employee  Benefit Plan Contract,  or
for the  Employee  Benefit  Plan  contributions  in a combined  Contract  for an
Employee Benefit Plan and Employer Sponsored 403(b) Plan, AUL will pay an amount
equal to the aggregate  Withdrawal  Values derived from the Variable  Account of
all  Participants  under the Contract  determined as of the end of the Valuation
Date on which termination is effective. Payment shall be made as described under
"Payments from the Variable Account." AUL will also pay amounts derived from the
Fixed Account in six annual  installments over five years.  Until all funds have
been paid by AUL,  either  the  interest  rate  determined  under  the  previous
                   -------------------------------------------------------------
paragraph or the average Current Rates of interest,  as determined by AUL on the
- -------------
first  installment  payment date,  less 1% (depending on the Contract),  will be
credited to the remaining  Withdrawal  Values.  Interest shall be paid with each
installment payment.


     Upon  termination  of a  Contract  used  in  connection  with  an  Employer
Sponsored 403(b) Program or a combined Contract for an Employee Benefit Plan and
Employer  Sponsored  403(b)  Plan,  AUL shall have the right to refuse to accept
further contributions. Upon such a termination, amounts attributable to Employer
Sponsored  403(b)  contributions  will be paid by AUL as  described in the prior
paragraph.

TERMINATION BY AUL


     AUL has the  right,  subject to  applicable  state law,  to  terminate  any
Participant's  Account  established under a Contract acquired in connection with
an Employee Benefit

<PAGE>
                                       27


Plan, a 457 Program,  or an Employer Sponsored 403(b) Program at any time during
the Contract Year if the Participant's  Account Value falls below $300 ($200 for
an  Employer  Sponsored  403(b)  Program or for a Contract  with both 403(b) and
401(a)  funds)  during the first  Contract  Year,  or $500 ($400 for an Employer
Sponsored  403(b)  Program or for a Contract  with both 403(b) and 401(a) funds)
during any  subsequent  Contract  Year,  provided  that at least six months have
elapsed  since the Owner's  last  contribution  to the  Contract.  AUL will give
notice to the Owner and the Participant that the Participant's  Account is to be
terminated.  Termination  shall be  effective  six months from the date that AUL
gives such notice,  provided  that any  contributions  made during the six month
notice period are  insufficient to bring the  Participant's  Account Value up to
the applicable minimum.  Single  Contribution  Contracts have a minimum required
contribution of $5,000.
                ------


     Upon termination of a Participant's  Account by AUL, AUL will pay an amount
equal to the  Participant's  Account  Value as of the close of  business  on the
effective date of termination.  Payment of this amount will be made within seven
days from such effective date of termination.

     AUL may, at its option,  terminate any Contract if there are no Participant
Accounts in existence under the Contract.

PAYMENTS FROM THE VARIABLE ACCOUNT

     Payment of an amount from the Variable Account  resulting from a surrender,
cash withdrawal,  transfer from a Participant's  Variable Account Value, payment
of the death  benefit,  or payment  upon  termination  by the Owner will be made
within  seven  days from the date a proper  request  is  received  at AUL's Home
Office.  However,  AUL can postpone the calculation or payment of such an amount
to the extent  permitted under  applicable  law, which is currently  permissible
only for any  period:  (a) during  which the New York Stock  Exchange  is closed
other than customary week-end and holiday closings,  (b) during which trading on
the New York Stock  Exchange is  restricted as determined by the SEC, (c) during
which an emergency,  as  determined by the SEC,  exists as a result of which (1)
disposal  of  securities  held  by  the  Variable   Account  is  not  reasonably
practicable,  or (2) it is not reasonably practicable to determine the value of
the assets of the Variable Account, or (d) for such other periods as the SEC may
by order permit for the  protection of  investors.  For  information  concerning
payment  of an amount  from the  Fixed  Account,  see "The  Fixed  Account"  and
"Termination by the Owner."

                             CHARGES AND DEDUCTIONS

PREMIUM TAX CHARGE

     Various  states and  municipalities  impose a tax on  premiums  received by
insurance  companies.  Whether or not a premium tax is imposed will depend upon,
among other things,  the Owner's state of residence,  the  Annuitant's  state of
residence,  and the insurance  tax laws and AUL's status in a particular  state.
AUL assesses a premium tax charge to reimburse  itself for premium taxes that it
incurs. This charge will be deducted as premium taxes are incurred by AUL, which
is usually when an annuity is effected.  Premium tax rates  currently range from
0% to 3.5%, but are subject to change by such governmental entities.

WITHDRAWAL CHARGE


     No deduction for sales charges is made from  contributions  for a Contract.
However,  if a cash withdrawal is made, a Participant's  Account is surrendered,
or the  Contract is  terminated  by the Owner,  then,  depending  on the type of
Contract,  a  withdrawal  charge  (which may also be referred to as a contingent
deferred sales charge) may be assessed by AUL if the  Participant's  Account has
not  been in  existence  for a  certain  period  of  time.  For  some  Recurring
                                                            --------------------
Contribution  Contracts,  for the first two Contract Years that a  Participant's
- ------------------------
Account  exists,  the amount  withdrawn  during a Contract Year that will not be
subject to a withdrawal charge is 10% of (1) the total of all contributions made
during the year that the  withdrawal is being made,  plus (2) the  Participant's
Account  Value at the  beginning  of the  Contract  Year.  After  the  first two
Contract Years, and until the withdrawal  charge has decreased to 0%, the amount
withdrawn  during a  Contract  Year that  will not be  subject  to an  otherwise
applicable  withdrawal charge is 10% of the  Participant's  Account Value at the
beginning of the Contract Year in which the  withdrawal  is being made.  Certain
                                                                         -------
Recurring Contribution 403(b) Contracts have withdrawal charges lower than those
- --------------------------------------------------------------------------------
shown below, but these Contracts do not contain provisions allowing the 10% free
- --------------------------------------------------------------------------------
out since they are benefit responsive in nature.
- ------------------------------------------------


The chart below  illustrates the amount of the withdrawal charge that applies to
the different  types of Contracts  based on the number of years that the Account
has been in existence.

- --------------------------------------------------------------------------------
Withdrawal  Charge  reaches  0% in the  eighth  Contract  Year.
- ---------------------------------------------------------------


     Withdrawal  charges  are not  imposed  for  many  benefits  provided  under
"benefit  responsive"   Contracts.   A  "benefit  responsive"  Contract  can  be
distinguished  from  a  Contract  that  is  not  "benefit   responsive"  by  the
contractual  condition that under a "benefit  responsive"  Contract,  withdrawal
charges are not imposed for payment of retirement, death,


<PAGE>
                                       28


disability,  termination  of  employment,  hardship,  loan,  age 70 1/2 required
minimum  distribution  benefits,  or  benefits  upon  attainment  of  age 59 1/2
(provided  that the age 59 1/2  benefit  is a taxable  distribution  paid to the
Participant and not to any other person or entity,  including any alternative or
substitute funding medium). Under certain circumstances,  withdrawal charges are
not imposed under "modified benefit responsive"  Contracts.  A "modified benefit
responsive"  Contract can be distinguished from a Contract that is not "modified
benefit responsive" by the contractual  condition that under a "modified benefit
responsive"  Contract,  withdrawal  charges are not  imposed  for cash  lump-sum
payments of death benefits, or, provided the Participant has (1) attained age 55
and has 10 years of service with the  employer  identified  in the Plan,  or (2)
attained age 62 for Plan benefits due to retirement,  disability, termination of
employment, hardships, loans, or required minimum distribution benefits pursuant
to Internal Revenue Code Section 401(a)(9) and Regulations issued thereunder, or
for benefits  upon  attainment  of age 59 1/2  (provided  that such benefit upon
attainment of age 59 1/2 is a taxable  distribution  paid to the Participant and
not to any other  person or entity,  including  any  alternative  or  substitute
funding medium).

     However,   even  in  benefit  responsive  or  modified  benefit  responsive
contracts,  withdrawal  charges will be applied to any  withdrawal to pay a Plan
benefit prior to notification of Contract  termination if the benefit is payable
because of, or the underlying  reason for payment of the benefit results in, the
termination or partial  termination of the Plan, as determined  under applicable
IRS guidelines.


     In no event will the  amount of any  withdrawal  charge,  when added to any
withdrawal  charges  previously  assessed  against any amount  withdrawn  from a
Participant's Account,  exceed 8.5% of the contributions made by or on behalf of
                               -----
a  Participant  under a Contract.  In  addition,  no  withdrawal  charge will be
imposed upon payment of a death benefit under the Contract.

     The withdrawal  charge will be used to recover certain expenses relating to
sales of the Contracts,  including commissions paid to sales personnel and other
promotional  costs. AUL reserves the right to increase the withdrawal charge for
any  Participant  Accounts  established  on or after the  effective  date of the
change, but the withdrawal charge will not exceed 8.5% of the contributions made
                                                  ----
by or on behalf of a Participant.


MORTALITY AND EXPENSE RISK CHARGE

     AUL deducts a daily charge from the assets of each  Investment  Account for
mortality  and expense  risks  assumed by AUL.  The charge is equal to an annual
rate of 1.25% of the average daily net assets of each Investment  Account.  This
amount is intended to compensate AUL for certain mortality and expense risks AUL
assumes in  offering  and  administering  the  Contracts  and in  operating  the
Variable Account. The 1.25% charge was originally based on estimates of .40% for
expense risk and .85% for mortality risk.

     The  expense  risk is the risk that AUL's  actual  expenses  in issuing and
administering the Contracts and operating the Variable Account will be more than
the charges  assessed for such expenses.  The mortality risk borne by AUL is the
risk that Annuitants,  as a group, will live longer than the Company's actuarial
tables  predict.  AUL may  ultimately  realize a profit  from this charge to the
extent it is not needed to address mortality and  administrative  expenses,  but
AUL may realize a loss to the extent the charge is not  sufficient.  AUL may use
any  profit  derived  from this  charge for any lawful  purpose,  including  any
distribution expenses not covered by the withdrawal charge.


VARIABLE INVESTMENT PLUS OPTION

     Certain  Contracts,  such  as  Employer  Sponsored  403(b)  Contracts,  457
Contracts, and Combination Contracts used in connection with an Employee Benefit
Plan and  Employer  Sponsored  403(b)  contributions  may,  at the option of the
Contract  Holder,  receive a portion of the Mortality and Expense Risk Charge in
the form of Accumulation Units credited to Participant  Accounts. If this Option
is elected by the Contract holder, and if the total amount of assets invested in
variable investment options meets certain underwriting  minimums,  then the Plus
Factor used to credit units on an annual basis will be as follows:

     Under different  Contracts for Employer  Sponsored 403(b) and 457 Programs,
the VIP Option may require different

<PAGE>
                                       29


minimum  contributions  during the first contract year and for subsequent years.
As an  example,  some  Contracts  will  only  require a minimum  of  $40,000  in
contributions  during the first contract year and $30,000 in ongoing  subsequent
contributions.  Up to 10% of any assets transferred into a Contract of this type
may qualify to meet the  required  first year  contribution  minimum and ongoing
contributions after the first contract year must be at least $30,000. For larger
Contractholders,  a different  option  requires a minimum of $1,000,000 in first
year  contributions  and $75,000  contributions  in  subsequent  years.  In this
instance, 100% of any assets transferred into a Contract may qualify to meet the
required first year contribution minimum and $25,000 in subsequent contributions
will  be  required  annually  thereafter.  Various  Contractholder  fees  may be
required   under   these   Contracts   including   Installation   Fees,   Annual
Administrative  Fees,  Form 5500  Reporting  Assistance  Fees, and a fee for not
using  electronic  means for  Participant  contributions.  The amount of the VIP
Factor for different options will vary, based on the amount of the contributions
(both  first  year and for  subsequent  years)  and the scale of the  Withdrawal
Charge  under the  Contract.  Generally,  if a Contract  has a lower  Withdrawal
Charge scale, the amount of the VIP Factor will be lower than for Contracts with
a higher Withdrawal Charge scale.

     AUL  reserves  the right at any time to  change  the  aggregate  investment
amounts, the Plus Factor and the underwriting minimums.

ADMINISTRATIVE CHARGE


     Under  both  Recurring  and  Single  Contribution Contracts, AUL deducts an
            ----             -----------
an administrative  charge from each Participant's Account equal to the lesser of
0.5% of the Participant's Account  Value or $7.50 per quarter /\ if the  account
                                                              --
exists on the quarterly Contract  Anniversary.  The charge is only assessed only
                                                ----------    ----
during the Accumulation  Period. When a Participant  annuitizes or surrenders on
any day other than a quarterly Contract  Anniversary,  a pro rata portion of the
charge  for that  portion of the  quarter  will not be  assessed.  The charge is
deducted  proportionately  from the Participant's  Account Value allocated among
the Investment Accounts and the Fixed Account. An administrative charge will not
be imposed on either Recurring or Single Contribution  Contracts if the value of
              ------           ---------
a  Participant's  Account  is equal to or more  than  $25,000  on the  quarterly
Contract Anniversary. /\  The purpose of this charge is to reimburse AUL for the
                      --
expenses  associated with  administration  of the Contracts and operation of the
Variable Account.


     The Administrative charge may, at the Employer's option, be billed directly
to and  paid  directly  by,  the  Employer  in lieu  of  being  deducted  from a
Participant's  Account  under  Employer  Sponsored  403(b)  Contracts  or  under
combined  Contracts  containing an Employee Benefit Plan and Employer  Sponsored
403(b)  contributions,  or the  charge may be paid on any other  basis  mutually
agreed  upon by the  Employer  and AUL.  AUL does not expect to profit from this
charge.


OTHER CHARGES

     AUL may charge the  Investment  Accounts  of the  Variable  Account for the
federal,  state, or local income taxes incurred by AUL that are  attributable to
the Variable  Account and its Investment  Accounts.  No such charge is currently
assessed. An Investment  Liquidation Charge or a Market Value Adjustment charge,
which applies only to Participants'  Fixed Account Values under a Contract,  may
be imposed upon  termination  by an Owner of a Contract  acquired in  connection
with an Employee Benefit Plan or 457 Program. See "Termination by the Owner."

VARIATIONS IN CHARGES


     AUL  may  reduce  or  waive  the  amount  of  the  withdrawal  charge,  the
administrative  charge, or the  mortality and expense risk charge for a Contract
where  the   expenses   associated   with  the  sale  of  the  Contract  or  the
administrative  costs  associated with the Contract are reduced.  A reduction in
the mortality and expense risk charge will  generally be made by offsetting  the
charge by applying the Variable  Investment  Plus Option.  As an example,  these
charges  may be  reduced in  connection  with  acquisition  of the  Contract  in
exchange  for  another  annuity  contract or in  exchange  for  another  annuity
contract  issued by AUL. AUL may also reduce or waive these charges on Contracts
sold  to the  directors  or  employees  of AUL  or any of its  affiliates  or to
directors or any employees of any of the Funds.


GUARANTEE OF CERTAIN CHARGES

     AUL  guarantees  that the  mortality  and  expense  risk  charge  shall not
increase.  AUL also  guarantees  that through the year 2000, the  administrative
charge may not  increase to more than $15.00 per  quarter.  After the year 2000,
AUL may  increase  the fee but  only to the  extent  necessary  to  recover  the
expenses  associated with  administration  of the Contracts and operation of the
Variable Account.

EXPENSES OF THE FUNDS

     Each Investment Account of the Variable Account purchases shares at the net
asset value of the  corresponding  Portfolio of one of the Funds.  The net asset
value reflects the investment  advisory fee and other expenses that are deducted
from the assets of the Portfolio.  The advisory fees and other expenses are more
fully described in the Funds' Prospectuses.

                                 ANNUITY PERIOD

GENERAL

     On the Annuity  Commencement  Date, the adjusted value of the Participant's
Account may be applied to provide an annuity under one of the options  described
below.  The  adjusted  value  will be  equal to the  value of the  Participant's
Account as of the Annuity  Commencement  Date, reduced by any applicable premium
or similar taxes and any outstanding loan balances and unpaid expense charges on
those loans.

     Generally, the Contracts provide for five annuity options, any one of which
may be elected if permitted by the particular Plan or applicable law. A lump-sum
distribution may also be elected under most Plans.  Other Annuity Options may be
available upon request at the  discretion of AUL. All Annuity  Options are fixed
and the annuity payments remain constant throughout the Annuity Period.  Annuity
payments are based upon annuity rates that vary with the Annuity Option selected
and the age of the  Annuitant  (except  that in the case of  Option 5, the Fixed
Period Option, age is not a consideration).  The annuity rates are based upon an
assumed interest rate of 2%, compounded annually.  If no Annuity Option has been
selected for a Participant, annuity payments will be made to the Annuitant under
an automatic option.  For 403(b) (other than Employer Sponsored 403(b) Programs)
and 457 Programs,  the automatic  option shall be an annuity  payable during the
lifetime of the Annuitant with payments certain for 120 months.  For an Employee
Benefit Plan or Employer Sponsored 403(b) Program, the automatic option shall be
an annuity  payable during the lifetime of the Annuitant  with payments  certain
for 120 months or, for a married Annuitant,  a Survivorship Annuity as described
in  Option 3  below.  For 408  Programs,  the  automatic  option  for  unmarried
Participants  shall  be  a  10  Year  Certain  and  Life  Annuity;  for  married
Participants,  the automatic  option shall be a 50%  Survivorship  Annuity.  For
"benefit  responsive"  Employer Sponsored 403(b) Contracts,  and for an Employee
Benefit Plan combined with an Employer  Sponsored 403(b)  Contract,  there is no
automatic annuity option.

     Once annuity payments have commenced, a Participant cannot surrender his or
her annuity and receive a lump-sum  settlement in lieu thereof and cannot change
the Annuity  Option.  If, under any option,  monthly  payments are less than $25
each,  AUL has the right to make either a lump-sum  settlement or to make larger
payments at quarterly,  semi-annual,  or annual intervals. AUL also reserves the
right to change the minimum payment amount. AUL will not allow  annuitization of
a  Participant's  Account  if the total  Account  Value is less than the  amount
specified in the Contract.  Should this occur,  a  Participant  will receive the
Account Value in a lump-sum settlement.

     Annuity payments will begin on the Annuity Commencement Date. No withdrawal
charge will be applied on this Date.


     A  Participant  or,  depending  on the  Contract,  an Owner on  behalf of a
Participant,  may  designate  an  Annuity  Commencement  Date,  Annuity  Option,
contingent  Annuitant,  and Beneficiary on an Annuity Election Form that must be
received  by AUL at its  Home  Office  at least  30 days  prior  to the  Annuity
Commencement  Date. AUL may also require  additional  information before annuity
payments  commence.  During the  lifetime of the  Participant  and up to 30 days
prior  to the  Annuity  Commencement  Date,  the  Annuity  Option,  the  Annuity
Commencement Date, or the designation of a contingent  Annuitant or Beneficiary,
if any, under an Annuity Option may be changed. To help ensure timely receipt of
the first annuity payment, a transfer of a Participant's  Variable Account Value
should be made to the  General  Account  (or to the AUL  American  Money  Market
                                         ---------------------------------------
Investment  Account if the  Contract so directs) at least two weeks prior to the
- ------------------------------------------------
Annuity Commencement Date.


ANNUITY OPTIONS

OPTION 1 - LIFE ANNUITY

     An annuity  payable  monthly during the lifetime of the Annuitant that ends
with the last monthly payment before the death of the Annuitant.

OPTION 2 - CERTAIN AND LIFE ANNUITY

     An annuity  payable  monthly  during the lifetime of the Annuitant with the
promise that if, at the death of the Annuitant, payments have been made for less
than a stated  period,  which may be five,  ten,  fifteen,  or twenty years,  as
elected,  annuity payments will be continued during the remainder of such period
to the Beneficiary.

OPTION 3 - SURVIVORSHIP ANNUITY

     An annuity payable monthly during the lifetime of the Annuitant, and, after
the  death  of the  Annuitant,  an  amount  equal to 50%,  66 2/3%,  or 100% (as
specified  in the  election)  of such  annuity  will  be paid to the  contingent
Annuitant  named in the  election  if and so long as such  contingent  Annuitant
lives.

     An  election  of this  option is  automatically  cancelled  if  either  the
Participant  or the contingent  Annuitant  dies before the Annuity  Commencement
Date.

OPTION 4 - INSTALLMENT REFUND LIFE ANNUITY

     An annuity  payable  monthly during the lifetime of the Annuitant that ends
with the last payment due prior to the death of the Annuitant,  except,  that at
the death of the Annuitant,  the  Beneficiary  will receive  additional  annuity
payments until the amount paid to purchase the annuity has been distributed.

OPTION 5 - FIXED PERIODS

     An annuity  payable  monthly  for a fixed  period (not less than 5 years or
more than 30 years) as elected,  with the guarantee that if, at the death of the
Annuitant,  payments  have been made for less than the  selected  fixed  period,
annuity  payments  will be continued  during the remainder of said period to the
Beneficiary.

SELECTION OF AN OPTION

     Participants should carefully review the Annuity Options with


<PAGE>
                                       31


their financial or tax advisers,  and reference should be made to the terms of a
particular Plan for pertinent limitations  respecting annuity payments and other
matters. For instance,  under requirements for retirement plans that qualify for
treatment under Sections 401, 403(b),  408, or 457 of the Internal Revenue Code,
annuity payments generally must begin no later than April 1 of the calendar year
following  the  calendar  year in  which  the  Participant  reaches  age 70 1/2,
provided the Participant is no longer employed.  For Options 2 and 5, the period
elected for receipt of annuity  payments  under the terms of the Annuity  Option
generally  may be no longer than the joint life  expectancy of the Annuitant and
Beneficiary  in the  year  that  the  Annuitant  reaches  age 70 1/2 and must be
shorter  than  such  joint  life  expectancy  if  the  Beneficiary  is  not  the
Annuitant's  spouse and is more than 10 years younger than the Annuitant.  Under
Option 3, if the contingent  Annuitant is not the Annuitant's spouse and is more
than 10 years  younger  than  the  Annuitant,  the 66 2/3%  and  100%  elections
specified above may not be available.


                                THE FIXED ACCOUNT

     Contributions  or  transfers  to the  Fixed  Account  become  part of AUL's
General Account. The General Account is subject to regulation and supervision by
the Indiana  Insurance  Department as well as the insurance laws and regulations
of other  jurisdictions in which the Contracts are  distributed.  In reliance on
certain  exemptive and exclusionary  provisions,  interests in the Fixed Account
have not been  registered as securities  under the  Securities  Act of 1933 (the
"1933  Act") and the Fixed  Account  has not been  registered  as an  investment
company  under the 1940 Act.  Accordingly,  neither  the Fixed  Account  nor any
interests therein are generally subject to the provisions of the 1933 Act or the
1940 Act.  AUL has been  advised  that the staff of the SEC has not reviewed the
disclosure in this Prospectus  relating to the Fixed Account.  This  disclosure,
however,  may be subject  to  certain  generally  applicable  provisions  of the
federal  securities laws relating to the accuracy and completeness of statements
made in the  Prospectus.  This  Prospectus  is generally  intended to serve as a
disclosure  document  only for  aspects of a  Contract  involving  the  Variable
Account and contains only selected information  regarding the Fixed Account. For
more  information  regarding  the Fixed  Account,  see the Contract  itself or a
Participant's Certificate.

INTEREST

     A Participant's  Fixed Account Value earns interest at fixed rates that are
paid by AUL. The Account  Value in the Fixed  Account  earns  interest at one or
more interest rates  determined by AUL at its discretion and declared in advance
("Current  Rate"),  which are guaranteed to be at least an annual effective rate
of either 3% or 4% per year ("Guaranteed  Rate") depending on the Contract.  AUL
will  determine  a Current  Rate from time to time,  and any  Current  Rate that
exceeds the Guaranteed Rate will be in effect for a period of at least one year.
If AUL determines a Current Rate in excess of the Guaranteed Rate, contributions
or transfers to a  Participant's  Account during the time the Current Rate is in
effect are  guaranteed to earn interest at that  particular  Current Rate for at
least one  year.  AUL may  declare a  different  Current  Rate for a  particular
contract based on costs of  acquisition to AUL or the level of service  provided
by AUL.  Transfers from other AUL annuity contracts may be transferred at a rate
of interest different than the Current Rate.

     Except for transfers from other AUL annuity contracts,  amounts contributed
or  transferred  to the Fixed  Account earn interest at the Current Rate then in
effect.  Amounts  transferred from other AUL annuity  contracts may not earn the
Current  Rate,  but  may,  at  AUL's  discretion,  continue  to earn the rate of
interest  which was paid under the former  Contract.  If AUL changes the Current
Rate, such amounts  contributed or transferred on or after the effective date of
the change earn interest at the new Current Rate;  however,  amounts contributed
or  transferred  prior to the effective  date of the change may earn interest at
the prior Current Rate or other Current Rate  determined by AUL.  Therefore,  at
any given time,  various portions of a Participant's  Fixed Account Value may be
earning  interest at  different  Current  Rates for  different  periods of time,
depending upon when such portions were originally  contributed or transferred to
the Fixed Account. AUL bears the investment risk for Participant's Fixed Account
Values and for paying  interest at the Current Rate on amounts  allocated to the
Fixed Account.

     For certain  Contracts,  AUL  reserves  the right at any time to change the
Guaranteed Rate of interest for any Participant Accounts established on or after
the  effective  date of the  change,  although  once a  Participant  Account  is
established,  the  Guaranteed  Rate may not be changed for the  duration of that
Account.

WITHDRAWALS AND TRANSFERS

     A Participant  (or a Contract Owner on behalf of a Participant)  may make a
full  surrender  or a partial  withdrawal  from his or her Fixed  Account  Value
subject to the provisions of the Contract.  A full surrender of a  Participant's
Fixed  Account  Value will result in a withdrawal  payment equal to the value of
the  Participant's  Fixed Account Value as of the day the surrender is effected,
minus any applicable  withdrawal charge and minus the Participant's  outstanding
loan  balance(s),  if any,  and any  expense  charges  due  thereon.  A  partial
withdrawal  may be requested for a specified  percentage or dollar amount of the
Participant's Fixed Account Value,  except,  where a Participant has outstanding
loans under a  Contract,  a partial  withdrawal  will be  permitted  only to the
extent that the  Participant's  remaining  Withdrawal Value in the Fixed Account
equals twice the total of the outstanding loans under the Participant's account.
The minimum amount that may be withdrawn from a Participant's share of the Fixed
Account is the lesser of $500 or the Participant's entire Fixed Account Value as
of the date the withdrawal  request is received by AUL at its Home Office.  If a
partial withdrawal is requested that would leave the Participant's Fixed Account

<PAGE>
                                       32



Value less than $500, then such partial  withdrawal request will be treated as a
request for a full withdrawal from the Fixed Account.  If a Participant has more
than one Account,  then the Account from which the partial  withdrawal  is to be
taken must be specified and any withdrawal restrictions shall be effective at an
Account level. For a further discussion of surrenders and partial withdrawals as
generally applicable to a Participant's Variable Account Value and Fixed Account
Value, see "Cash Withdrawals."


     A  Participant's  Fixed  Account  Value may be  transferred  from the Fixed
Account  to the  Variable  Account  subject  to  certain  limitations.  Where  a
Participant has outstanding loans under a Contract, a transfer will be permitted
only to the extent  that the  Participant's  remaining  Withdrawal  Value in the
Fixed  Account  equals  twice  the  total of the  outstanding  loans  under  the
Participant's  Account. The minimum transfer from any Investment Account or from
the Fixed Account is the lesser of $500 or a Participant's  entire Account Value
in that  Investment  Account or in the Fixed Account as of the date the transfer
request is received by AUL at its Home Office,  provided,  however, that amounts
transferred  from the Fixed  Account to an Investment  Account  during any given
Contract Year cannot exceed 20% of the  Participant's  Fixed Account Value as of
the beginning of that Contract Year.  However,  if a Participant's Fixed Account
Value at the beginning of the Contract Year is less than $2,500, the amount that
will be transferred  for that Contract Year from the Fixed Account is the lesser
of $500 or the entire Fixed Account Value as of the date the transfer request is
received by AUL at its Home Office.  If, after any transfer,  the  Participant's
remaining  Account Value in an Investment  Account or in the Fixed Account would
be less than $500, then such request will be treated as a request for a transfer
of the entire Account Value.  Transfers and withdrawals of a Participant's Fixed
Account Values will be effected on a first-in, first-out basis. If a Participant
has more than one  Account,  then the Account  from which the  transfer is to be
taken must be specified and any transfer  restrictions  shall be effective at an
Account level.  The 20% restriction on transfers  during any given Contract Year
from the Fixed  Account to an  Investment  Account  shall not apply to  Employer
Sponsored 403(b) Programs,  Employee Benefit Plans,  Employee Benefit Plans in a
combined  Contract for an Employee  Benefit Plan and Employer  Sponsored  403(b)
Plan,  or 408 SEP or SIMPLE IRA  Contracts  if: (1) the Owner (or Plan  Sponsor)
selects the Fixed Interest Account as an Investment Option to Participants under
the  Contract;  (2) the Owner (or Plan Sponsor) does not select the AUL American
Money  Market   Investment   Account  as  an  available   Investment  Option  to
Participants  under the  Contract,  and (3)  following a transfer from the Fixed
Account to the Variable  Account by a Participant,  a transfer back to the Fixed
Account shall be allowed only after 90 days have elapsed since the last previous
                                                                   ----
transfer from the Fixed Account.  Except as noted previously,  generally,  there
are no  limitations  on the  number of  transfers  between  Investment  Accounts
available  under a Contract or the Fixed  Account.  In addition,  no charges are
currently imposed upon transfers.  AUL reserves the right,  however, at a future
date,  to change the  limitation  on the minimum  transfer,  to assess  transfer
charges,  to change  the limit on  remaining  balances,  to limit the number and
frequency of transfers,  and to suspend the transfer  privilege or the telephone
transfer authorization.  Any transfer from an Investment Account of the Variable
Account  shall be  effective  as of the end of the  Valuation  Date in which AUL
receives the request in proper form.  For a discussion of transfers as generally
applicable to a  Participant's  Variable  Account Value and Fixed Account Value,
see "Transfers of Account Value."


TRANSFER OF INTEREST OPTION

     Participants  may elect to use  interest  earned in their Fixed  Account to
purchase  Accumulation Units in one or more Variable  Accounts.  Upon receipt at
AUL's Home Office of properly executed written  instructions to do so, AUL will,
on the last business day of each month and monthly thereafter,  use the interest
earned in the Fixed Account during that month to purchase  Accumulation Units at
the corresponding  Accumulation Unit Value on each date that a purchase is made.
To elect this Option,  the Participant  must have  previously  provided AUL with
instructions  specifying  the  Variable  Investment  Account or  Accounts  to be
purchased and a percentage allocation among Investment Accounts if more than one
Investment  Account has been elected.  If no such  instructions  are received by
AUL, then the  Participant's  prior investment  allocation  instructions will be
used by AUL to allocate  purchases  under this Option.


     To participate in this Option, a Participant's  Fixed Account Value must be
greater than $10,000 and the  Participant's  Account must have been in existence
                     -----------------------------------------------------------
for a period of at least one year. Amounts  transferred out of the Fixed Account
- ----------------------------------
under this Option will be  considered a part of the 20% maximum  amount that can
be  transferred  from the Fixed Account to a Variable  Account  during any given
Contract Year.


CONTRACT CHARGES

     The withdrawal charge will be the same for amounts surrendered or withdrawn
from a Participant's Fixed Account Value as for amounts surrendered or withdrawn
from a Participant's  Variable  Account Value. In addition,  the  administrative
charge  will  be the  same  whether  or not a  Participant's  Account  Value  is
allocated to the Variable Account or the Fixed Account. The charge for mortality
and  expense  risks will not be  assessed  against  the Fixed  Account,  and any
amounts  that AUL pays for income taxes  allocable to the Variable  Account will
not be charged against the Fixed Account.  In addition,  the investment advisory
fees and  operating  expenses  paid by the Funds  will not be paid  directly  or
indirectly by  Participants  to the extent the Account Value is allocated to the
Fixed Account; however, such Participants will not participate in the investment
experience of the Variable Account. See "Charges and Deductions."

     An Investment  Liquidation Charge or Market Value Adjustment,  depending on
the Contract, may be imposed upon termination by an Owner of a Contract acquired
in connection with an Employee Benefit Plan or 457 Program.  See "Termination by
the Owner."

                                       33

PAYMENTS FROM THE FIXED ACCOUNT

     Surrenders,  withdrawals,  and transfers from the Fixed Account and payment
of a death benefit based upon a Participant's Fixed Account Value may be delayed
for up to six months  after a written  request in proper form is received by AUL
at its Home Office.  During the period of deferral,  interest at the  applicable
interest rate or rates will continue to be credited to the  Participant's  Fixed
Account Value.  For  information  on payment upon  termination by the Owner of a
Contract  acquired in  connection  with an Employee  Benefit  Plan,  an Employer
Sponsored 403(b) Program, or a 457 Program, see "Termination by the Owner."

LOANS FROM THE FIXED ACCOUNT

     A  Participant  under a 403(b)  Program,  other than an Employer  Sponsored
403(b)  Program,  who has a  Participant  Account Value in the Fixed Account may
borrow money from AUL using his or her Fixed  Account Value as the only security
for the loan by submitting a proper written request to AUL's Home Office. A loan
may be taken any time prior to the Annuity  Commencement  Date. The minimum loan
that can be taken at any time is $2000,  unless a lower  minimum  loan amount is
specified by state law or Department of Labor  regulations.  The maximum  amount
that can be  borrowed at any time is an amount  which,  when  combined  with the
largest loan balance  during the prior 12 months,  does not exceed the lesser of
(1) 50% of the  Participant's  Withdrawal  Value in the  Fixed  Account,  or (2)
$50,000. The Participant's  Withdrawal Value in the Fixed Account, which must be
at least  twice the  amount of the  outstanding  loan  balance,  shall  serve as
security for the loan,  and shall  continue to earn interest as described  under
"Interest."  Payment  by AUL of the loan  amount  may be  delayed  for up to six
months.  If a Participant has more than one Participant  Account invested in the
Fixed  Account,  then the account in which funds are to be held as security  for
the loan must be specified,  and any loan restrictions  shall be effective at an
Account level.

     Interest will be charged for the loan,  and will accrue on the loan balance
from the effective  date of any loan.  The interest rate will be declared by AUL
at the  beginning  of each  calendar  quarter,  or, with respect to Contracts or
Participants in some states,  annually.  The interest charged will be determined
under a procedure specified in the loan provision of the Contract;  the interest
rate generally follows the Moody's Corporate Bond Yield Average-Monthly  Average
Corporates as published by Moody's Investors Service.  However, no change from a
previously  established  rate  will be made in an  amount  less than .50% in any
periodic adjustment. The Contract should be consulted for more information.  The
loan balance shall also be subject to a loan expense  charge equal to 2% of each
loan repayment unless such a charge is prohibited by state law.

     Loans to  Participants  must be repaid within a term of five years,  unless
the  Participant  certifies  to AUL  that the  loan is to be used to  acquire  a
principal  residence for the Participant,  in which case the term may be longer.
Loan  repayments must be made at least  quarterly.  Upon receipt of a repayment,
AUL will  deduct the 2% expense  charge  from the  repayment  and will apply the
balance  first  to  any  accrued  interest  and  then  to the  outstanding  loan
principal.

     If a loan either  remains  unpaid at the end of its term, or if at any time
during the Accumulation  Period, 102% of the total of all the Participant's loan
balances  equals  the  Participant's  Withdrawal  Value  allocated  to the Fixed
Account,  then AUL will deduct these loan balances, as well as an expense charge
equal to 2% of the  outstanding  loan  balances,  from the  Participant's  Fixed
Account Value to the extent  permitted by law. If a Participant  has outstanding
loans,  then  withdrawals or transfers to the Variable Account will be permitted
only to the extent  that the  remaining  Participant's  Withdrawal  Value in the
Fixed Account equals or exceeds twice the total of any  outstanding  loans under
the  Contract.  All loan  balances  plus the 2% expense  charge  must be paid or
satisfied in full before any amount  based upon a  Participant's  Fixed  Account
Value is paid upon surrender,  as a death benefit, upon annuitization,  or other
permitted distribution.

     The  restrictions  or  limitations  stated  above may be  modified,  or new
restrictions  and  limitations  added,  to the extent  necessary  to comply with
Section  72(p) of the Internal  Revenue Code or its  regulations,  under which a
loan will not be  treated as a  distribution  under a 403(b)  Program,  or other
applicable  law as  determined  by AUL.  It  should be noted  that the  Internal
Revenue Service has issued regulations which cause the outstanding  balance of a
loan to be  treated  as a taxable  distribution  if the loan is not  repaid in a
timely manner.

DESIGNATION AND CHANGE OF BENEFICIARY

     The Beneficiary  designation contained in an enrollment form application to
open a  Participant's  Account will remain in effect until  changed.  Payment of
benefits to any Beneficiary are subject to the specified  Beneficiary  surviving
the Participant.  Unless  otherwise  provided,  if no designated  Beneficiary is
living upon the death of the Participant prior to the Annuity Commencement Date,
the Participant's  estate is the Beneficiary.  Unless otherwise provided,  if no
designated  Beneficiary  under an  Annuity  Option is living  after the  Annuity
Commencement  Date, upon the death of the Annuitant,  the Annuitant's  estate is
the Beneficiary.

     Subject  to  the  rights  of an  irrevocably  designated  Beneficiary,  the
designation  of a  Beneficiary  may be  changed or revoked at any time while the
Participant  is living by filing with AUL a written  beneficiary  designation or
revocation in such form as AUL may require. The change or revocation will not be
binding upon AUL until it is received by AUL at its Home  Office.  When it is so
received, the change or revocation will be effective as of the date on which the
beneficiary  designation or revocation was signed,  but the change or revocation
will be without  prejudice to AUL if any payment has been made or any action has
been taken by AUL prior to receiving the change or revocation.

     Reference  should  be made to the  terms  of the  particular  Plan  and any
applicable  law  for  any  restrictions  on  the  beneficiary  designation.  For
instance,  under an Employee Benefit Plan or Employer  Sponsored 403(b) Program,
the Beneficiary (or contingent  Annuitant) must be the  Participant's  spouse if
the  Participant  is  married,  unless  the  spouse  properly  consents  to  the
designation of a Beneficiary (or contingent Annuitant) other than the spouse.

ASSIGNABILITY

     No benefit or privilege under a Contract may be sold, assigned, discounted,
or pledged as  collateral  for a loan or as security for the  performance  of an
obligation or for any other purpose to any person or entity other than AUL.

PROOF OF AGE AND SURVIVAL

     AUL may  require  proof of age or  survival  of any  person  on whose  life
annuity payments depend.

MISSTATEMENTS

     If the age of an Annuitant or contingent Annuitant has been misstated,  the
correct amount paid or payable by AUL shall be such as the Participant's Account
Value would have provided for the correct age.

ACCEPTANCE OF NEW PARTICIPANTS OR CONTRIBUTIONS

     AUL  reserves  the  right to  refuse  to  accept  new  Participants  or new
Contributions to a Contract at any time.


                              FEDERAL TAX MATTERS

INTRODUCTION

     The  Contracts  described  in  this  Prospectus  are  designed  for  use by
Employer,  association, and other group retirement plans under the provisions of
Sections  401,  403,  408, and 457 of the Internal  Revenue Code  ("Code").  The
ultimate  effect  of  Federal  income  taxes on  values  under a  Contract,  the
Participant's  Account, on annuity payments, and on the economic benefits to the
Owner,  the Participant,  the Annuitant,  and the Beneficiary or other payee may
depend upon the type of Plan for which the Contract is purchased and a number of
different  factors.  The  discussion  contained  herein and in the  Statement of
Additional   Information   is  general  in  nature.   It  is  based  upon  AUL's
understanding of the present Federal income tax laws as currently interpreted by
the Internal  Revenue  Service  ("IRS"),  and is not intended as tax advice.  No
representation  is made regarding the likelihood of  continuation of the present
Federal income tax laws or of the current  interpretations by the IRS. Moreover,
no attempt is made to consider any  applicable  state or other laws.  Because of
the  inherent  complexity  of such laws and the fact that tax results  will vary
according to the particular  circumstances  of the Plan or individual  involved,
any person  contemplating the purchase of a Contract,  or becoming a Participant
under a Contract,  or receiving annuity payments under a Contract should consult
a qualified tax adviser.

AUL DOES NOT MAKE ANY GUARANTEE  REGARDING THE TAX STATUS,  FEDERAL,  STATE,  OR
LOCAL, OF ANY CONTRACT OR PARTICIPANT'S ACCOUNT OR ANY TRANSACTION INVOLVING THE
CONTRACTS.

TAX STATUS OF THE COMPANY AND THE VARIABLE ACCOUNT

     AUL is taxed as a life insurance  company under Part I, Subchapter L of the
Code.  Because the  Variable  Account is not taxed as a separate  entity and its
operations  form a part of AUL, AUL will be  responsible  for any Federal income
taxes that become  payable with  respect to the income of the Variable  Account.
However,  each  Investment  Account  will  bear  its  allocable  share  of  such
liabilities.  Under current law, no item of dividend income, interest income, or
realized  capital  gain  attributable,  at a  minimum,  to  appreciation  of the
Investment Accounts will be taxed to AUL to the extent it is applied to increase
reserves under the Contracts.

     Each of the Funds in which the  Variable  Account  invests  has advised AUL
that it intends to qualify as a "regulated  investment  company" under the Code.
AUL does not guarantee that any Fund will so qualify. If the requirements of the
Code are met, a Fund will not be taxed on amounts  distributed on a timely basis
to the Variable Account.  Were such a Fund not to so qualify,  the tax status of
the  Contracts  as  annuities  might be lost,  which could  result in  immediate
taxation of amounts  earned under the  Contracts  (except those held in Employee
Benefit Plans and 408 Programs).

     Under regulations  promulgated  under Code Section 817(h),  each Investment
Account must meet certain diversification standards.  Generally, compliance with
these  standards is determined  by taking into account an  Investment  Account's
share of assets of the  appropriate  underlying  Fund. To meet this test, on the
last day of each  calendar  quarter,  no more than 55% of the total  assets of a
Fund  may be  represented  by any  one  investment,  no  more  than  70%  may be
represented by any two  investments,  no more than 80% may be represented by any
three  investments,  and no  more  than  90%  may  be  represented  by any  four
investments.  For the purposes of Section 817(h),  securities of a single issuer
generally are treated as one investment,  but  obligations of the U.S.  Treasury
and each U.S.  Governmental  agency or instrumentality  generally are treated as
securities of separate issuers.

TAX TREATMENT OF RETIREMENT PROGRAMS

     The Contracts described in this Prospectus are offered for use with several
types of  retirement  programs as  described in "The  Contracts."  The tax rules
applicable to  Participants  in such  retirement  programs vary according to the
type of retirement plan and its terms and conditions.  Therefore,  no attempt is
made  herein to  provide  more  than  general  information  about the use of the
Contracts with the various types of retirement programs. Participants under such
programs,  as well as Owners,  Annuitants,  Beneficiaries  and other  payees are
cautioned that the rights of any person to

<PAGE>
                                       35

any benefits  under these programs may be subject to the terms and conditions of
the Plans  themselves,  regardless of the terms and  conditions of the Contracts
issued in connection therewith.

     Generally, no taxes are imposed on the increases in the value of a Contract
by  reason  of  investment   experience  or  Employer   contributions   until  a
distribution  occurs,  either as a lump-sum payment or annuity payments under an
elected Annuity Option or in the form of cash withdrawals,  surrenders, or other
distributions prior to the Annuity Commencement Date.

     The amounts that may be contributed to the Plans are subject to limitations
that may vary  depending on the type of Plan. In addition,  early  distributions
from most Plans may be subject to penalty taxes, or in the case of distributions
of amounts contributed under salary reduction  agreements,  could cause the Plan
to be disqualified.  Furthermore,  distributions  from most Plans are subject to
certain  minimum  distribution  rules.  Failure to comply with these rules could
result in  disqualification  of the Plan or  subject  the  Annuitant  to penalty
taxes. As a result, the minimum  distribution rules could limit the availability
of certain Annuity Options to Participants and their Beneficiaries.

     Below are brief  descriptions  of various types of retirement  programs and
the use of the Contracts in connection therewith.

EMPLOYEE BENEFIT PLANS

     Code Section 401 permits  business  employers and certain  associations  to
establish various types of retirement plans for employees. Such retirement plans
may permit the purchase of Contracts to provide benefits thereunder.


     If a  Participant  under an  Employee  Benefit  Plan  receives  a  lump-sum
distribution, the portion of the distribution equal to any contribution that was
taxable  to the  Participant  in the year when paid is  received  tax free.  The
balance  of the  distribution  will  be  treated  as  ordinary  income.  Special
five-year forward averaging provisions under Code Section 402 may be utilized on
any  amount  subject  to  ordinary  income  tax  treatment,  provided  that  the
Participant has reached age 59 1/2, has not previously elected forward averaging
for a distribution from any Employee Benefit Plan after reaching age 59 1/2, and
has  not  rolled  over a  partial  distribution  from a  similar  plan  into  an
individual  retirement  account or annuity.  Special  ten-year  averaging  and a
capital-gains  election  may be available  to a  Participant  who reached age 50
before 1986.

     Under an Employee  Benefit Plan under Section 401 of the Code, when annuity
payments commence (as opposed to a lump-sum  distribution),  under Section 72 of
the Code, the portion of each payment  attributable to  contributions  that were
taxable to the  Participant  in the year made,  if any, is  excluded  from gross
income as a return of the Participant's  investment.  The portion so excluded is
determined  at the time the  payments  commence  by dividing  the  Participant's
investment  in the Contract by the  expected  return.  The periodic  payments in
excess of this  amount are taxable as ordinary  income.  Once the  Participant's
investment has been recovered,  the full annuity payment will be taxable. If the
annuity should stop before the investment  has been  received,  the  unrecovered
portion is deductible on the Annuitant's  final return.  If the Participant made
no  contributions  that were taxable to the Participant in the year made,  there
would be no portion excludable.

403(b) PROGRAMS

     Code Section  403(b)  permits  public  school  systems and certain types of
charitable,  educational, and scientific organizations specified in Code Section
501(c)(3)  to purchase  annuity  contracts  on behalf of their  employees,  and,
subject to certain  limitations,  allows  employees  of those  organizations  to
exclude the amount of  contributions  from gross  income for Federal  income tax
purposes.

     If a  Participant  under a 403(b)  Program  makes a  surrender  or  partial
withdrawal from the Participant's  Account,  the Participant will realize income
taxable at ordinary tax rates on the full amount  received.  See "Constraints on
Withdrawal - 403(b)  Programs."  Since,  under a 403(b)  Program,  contributions
generally  are  excludable  from the taxable  income of the  employee,  the full
amount received will usually be taxable as ordinary income when annuity payments
commence.

408 PROGRAMS

     Code Sections 219 and 408 permit  eligible  individuals to contribute to an
individual  retirement  program,  including  Simplified  Employee Pension Plans,
SIMPLE  IRA plans and  Employer/Association  Established  Individual  Retirement
Account Trusts,  known as an Individual  Retirement  Account ("IRA").  These IRA
accounts are subject to limitations on the amount that may be  contributed,  the
persons who may be eligible, and on the time when distributions may commence. In
addition, certain distributions from some other types of retirement plans may be
placed on a  tax-deferred  basis in an IRA.  Sale of the  Contracts for use with
IRA's may be subject to special  requirements  imposed by the  Internal  Revenue
Service.  Purchasers  of the  Contracts  for such purposes will be provided with
such  supplementary  information  as may be  required  by the  Internal  Revenue
Service  or other  appropriate  agency,  and will have the  right to revoke  the
Contract under certain circumstances.

     If a  Participant  under  a  408  Program  makes  a  surrender  or  partial
withdrawal  from the  Participant's  Account,  the  Participant  generally  will
realize income taxable at ordinary tax rates on the full amount received. Since,
under a 408 Program,  contributions  generally are  deductible  from the taxable
income of the  employee,  the full amount  received  will  usually be taxable as
ordinary income when annuity payments commence.

457 PROGRAMS

     Section 457 of the Code permits  employees  of state and local  governments
and units and  agencies  of state and local  governments  as well as  tax-exempt
organizations  described in Section  501(c)(3) of the Code to defer a portion of
their compensation without paying current taxes. The employees


<PAGE>
                                       36

must be Participants in an eligible deferred compensation plan.

     If the Employer sponsoring a 457 Program requests and receives a withdrawal
for an  eligible  employee in  connection  with a 457  Program,  then the amount
received by the employee will be taxed as ordinary  income.  Since,  under a 457
Program,  contributions  are excludable from the taxable income of the employee,
the full  amount  received  will be  taxable as  ordinary  income  when  annuity
payments commence or other distribution is made.

     If a Contract is used in connection with an unqualified,  unfunded deferred
compensation benefits to a select group of employees,  contributions to the Plan
are  includible  in the  employee's  gross income when these amounts are paid or
otherwise made available to the employee.

TAX PENALTY

     Any  distribution  made to a Participant from an Employee Benefit Plan or a
408 Program other than on account of one or more of the following events will be
subject to a 10% penalty tax on the amount distributed:

   (a) the Participant has attained age 59 1/2;
   (b) the Participant has died; or
   (c) the Participant is disabled.

     In  addition,  a  distribution  from an Employee  Benefit  Plan will not be
subject to a 10% penalty tax on the amount  distributed if the Participant is 55
and has separated from service. Distributions received at least annually as part
of a series of  substantially  equal periodic  payments made for the life of the
Participant  will not be  subject to a penalty  tax.  Certain  amounts  paid for
medical care also may not be subject to a penalty tax.

     Any  permitted  distribution  from a  Participant  Account  under a  403(b)
Program will be subject to a 10% excise tax unless the Participant satisfies one
of the exemptions  listed above for Employee  Benefit Plans. See "Constraints on
Withdrawals - 403(b) Programs."


WITHHOLDING

     Distributions  from an Employee Benefit Plan under Code Section 401(a) or a
403(b)  Program to an employee,  surviving  spouse,  or former  spouse who is an
alternate  payee under a qualified  domestic  relations  order, in the form of a
lump-sum  settlement  or periodic  annuity  payments for a fixed period of fewer
than 10 years are subject to mandatory  federal income tax withholding of 20% of
the  taxable  amount of the  distribution,  unless the  distributee  directs the
transfer of such amounts to another  Employee  Benefit Plan or 403(b) Program or
to an Individual  Retirement  Account under Code Section 408. The taxable amount
is the  amount of the  distribution,  less the  amount  allocable  to  after-tax
contributions.

     All other types of  distributions  from  Employee  Benefit Plans and 403(b)
Programs, and all distributions from Individual Retirement Accounts, are subject
to federal income tax  withholding on the taxable amount unless the  distributee
elects not to have the  withholding  apply.  The amount withheld is based on the
type of distribution.  Federal tax will be withheld from annuity payments (other
than those subject to mandatory  20%  withholding)  pursuant to the  recipient's
withholding  certificate.  If no withholding  certificate is filed with AUL, tax
will be withheld on the basis that the payee is married  with three  withholding
exemptions.  Tax on all surrenders and lump-sum  distributions  from  Individual
Retirement Accounts will be withheld at a flat 10% rate.

     Withholding on annuity payments and other  distributions  from the Contract
will be made in accordance with regulations of the Internal Revenue Service.

EFFECT OF TAX DEFERRED ACCUMULATION

     In general, participants in retirement plans that own annuity contracts are
not  taxed on  increases  in the  value of their  accounts  until  some  form of
distribution  is made to the  Participant.  Due to this tax deferral  during the
accumulation  period,  participation  in a retirement  plan funded by an annuity
contract  generally  results in more rapid growth than a  comparable  investment
under which  contributions  and increases in value are taxed on a current basis.
The chart  illustrates  this benefit by comparing a retirement plan that invests
in a  variable  annuity  contract  to  accumulation  from  an  investment  whose
contributions  and gains are taxed on a  current  basis.  The chart  illustrates
accumulation of $250 of monthly before-tax  contributions  going into an annuity
contract for a retirement  plan and $172.50 of monthly  after-tax  contributions
going into a conventional  savings plan ($250 minus $77.50 of income taxes based
on an  assumed  combined  rate of 31% for state and  federal  income  tax equals
$172.50 of after-tax  contributions).  Each  contribution  is made at the end of
each month.  This chart also assumes a 6% before-tax  earnings rate.  Values for
Tax  Deferred  Accumulation  After  Tax and Pre-Tax  Accumulation  Value  do not
reflect the  deduction  for  mortality and expense risk charges under a variable
annuity  contract and the values shown for Tax Deferred  Accumulation  After Tax
would be lower if these  charges  were  included.  Values shown for Tax Deferred
Accumulation After Tax reflect appropriate  withdrawal charges at the end of the
periods shown.

     The  hypothetical  rate of return used in the chart is an assumption  only,
and no  implication is intended that the return is guaranteed in any way or that
it represents  an average or expected  rate of return over the period  depicted.
The portion of a Participant's  Account Value that exceeds the variable  annuity
contract owner's or  participant's  investment in the  Participant's  Account is
taxed at ordinary income tax rates upon distribution,  and a 10% tax penalty may
apply to withdrawals taken before the taxpayer reaches the age of 59 1/2.

     After  state and  federal  income  tax at 31% has been  paid on the  amount
distributed, with a variable annuity, after 5 years there would be an additional
$100 available;  after 10 years there would be an additional  $2,541  available;
after 20 years, there would be an additional $14,496 available;  after 30 years,
there would be an additional $47,016 available;  and after 40 years, there would
be an additional $121,922 available.  Tax rates may vary for different taxpayers
from the 31% used in this chart,  which would  result in  different  values from
those shown in the chart.

                                OTHER INFORMATION

VOTING OF SHARES OF THE FUNDS

     AUL is the legal owner of the shares of the Portfolios of the Funds held by
the Investment  Accounts of the Variable Account. In accordance with its view of
present  applicable  law, AUL will exercise  voting rights  attributable  to the
shares of the Funds held in the  Investment  Accounts at any regular and special
meetings  of the  shareholders  of the Funds on  matters  requiring  shareholder
voting under the 1940 Act.

     AUL will exercise these voting rights based on  instructions  received from
persons having the voting interest in corresponding  Investment  Accounts of the
Variable  Account  and  consistent  with any  requirements  imposed on AUL under
contracts with any of the Funds, or under applicable law.  However,  if the 1940
Act  or  any  regulations  thereunder  should  be  amended,  or if  the  present
interpretation  thereof should change, and as a result AUL determines that it is
permitted  to vote the shares of the Funds in its own right,  it may elect to do
so.

     The person having the voting  interest under a Contract is the Owner or the
Participant, depending on the type of Plan. Generally, a Participant will have a
voting  interest  under a Contract to the extent of the vested portion of his or
her Account  Value.  AUL shall send to each Owner or  Participant a Fund's proxy
materials and forms of instruction by means of which  instructions  may be given
to AUL on how to exercise voting rights  attributable  to the Funds' shares.  In
the case of a Contract  acquired in connection with an Employee  Benefit Plan or
an Employer Sponsored 403(b) Program,  AUL may furnish the Owner with sufficient
Fund proxy materials and voting  instruction forms for all Participants  under a
Contract with any voting interest.

     Unless otherwise required by applicable law or under a contract with any of
the Funds,  with  respect to each of the Funds,  the number of Fund  shares of a
particular  Portfolio  as to which  voting  instructions  may be given to AUL is
determined  by  dividing  the  value  of all of the  Accumulation  Units  of the
corresponding  Investment Account  attributable to a Contract or a Participant's
Account on a particular  date by the net asset value per share of that Portfolio
as of the same date. Fractional votes will be counted. The number of votes as to
which  voting  instructions  may be  given  will be  determined  as of the  date
coincident  with the date  established  by a Fund for  determining  shareholders
eligible to vote at the  meeting of the Fund.  If required by the SEC or under a
contract  with any of the  Funds,  AUL  reserves  the  right to  determine  in a
different  fashion  the voting  rights  attributable  to the shares of the Fund.
Voting instructions may be cast in person or by proxy.

     Voting rights  attributable  to the Contracts or  Participant  Accounts for
which no timely  voting  instructions  are received  will be voted by AUL in the
same proportion as the voting instructions which are received in a timely manner
for all Contracts and  Participant  Accounts  participating  in that  Investment
Account.  AUL will vote shares of any Investment  Account,  if any, that it owns
beneficially in its own  discretion,  except that if a Fund offers its shares to
any  insurance  company  separate  account that funds  variable  life  insurance
contracts  or if  otherwise  required by  applicable  law, AUL will vote its own
shares in the same proportion as the voting  instructions that are received in a
timely  manner for  Contracts  and  Participant  Accounts  participating  in the
Investment Account.


<PAGE>
                                       38


     Neither the Variable Account nor AUL is under any duty to inquire as to the
instructions  received  or the  authority  of Owners or others to  instruct  the
voting of shares of any of the Funds.

SUBSTITUTION OF INVESTMENTS

     AUL  reserves  the  right,  subject to  compliance  with the law as then in
effect, to make additions to, deletions from, substitutions for, or combinations
of the  securities  that  are held by the  Variable  Account  or any  Investment
Account or that the Variable Account or any Investment Account may purchase.  If
shares of any or all of the  Portfolios  of a Fund should no longer be available
for investment,  or if, in the judgment of AUL's management,  further investment
in shares of any or all Portfolios of a Fund should become inappropriate in view
of the purposes of the Contracts, AUL may substitute shares of another Portfolio
of a  Fund  or of a  different  fund  for  shares  already  purchased,  or to be
purchased in the future under the Contracts. AUL may also purchase,  through the
Variable Account,  other securities for other classes of contracts,  or permit a
conversion  between classes of contracts on the basis of requests made by Owners
or as permitted by Federal law.

     Where  required  under  applicable  law, AUL will not substitute any shares
attributable  to an Owner's  interest in an  Investment  Account or the Variable
Account without notice, Owner or Participant  approval, or prior approval of the
SEC or a state insurance commissioner, and without following the filing or other
procedures established by applicable state insurance regulators.

     AUL also reserves the right to establish additional  Investment Accounts of
the Variable Account that would invest in a new Portfolio of a Fund or in shares
of another investment  company, a series thereof,  or other suitable  investment
vehicle.  New Investment  Accounts may be established in the sole  discretion of
AUL, and any new Investment Account will be made available to existing Owners on
a basis to be  determined by AUL. Not all  Investment  Accounts may be available
under a  particular  Contract.  AUL may also  eliminate  or combine  one or more
Investment Accounts or cease permitting new allocations to an Investment Account
if, in its sole discretion, marketing, tax, or investment conditions so warrant.

     Subject to any  required  regulatory  approvals,  AUL reserves the right to
transfer  assets of any  Investment  Account of the Variable  Account to another
separate account or Investment Account.

     In the event of any such  substitution  or change,  AUL may, by appropriate
endorsement,  make such changes in these and other Contracts as may be necessary
or appropriate to reflect such substitution or change. If deemed by AUL to be in
the best  interests of persons  having  voting rights under the  Contracts,  the
Variable  Account may be operated as a management  investment  company under the
1940 Act or any other form permitted by law, it may be  deregistered  under that
Act in the event such registration is no longer required,  or it may be combined
with  other  separate  accounts  of  AUL or an  affiliate  thereof.  Subject  to
compliance  with  applicable  law,  AUL also may combine one or more  Investment
Accounts and may establish a committee,  board,  or other group to manage one or
more aspects of the operation of the Variable Account.

CHANGES TO COMPLY WITH LAW AND AMENDMENTS

     AUL reserves the right,  without the consent of Owners or Participants,  to
make any change to the  provisions  of the  Contracts to comply with, or to give
Owners or  Participants  the benefit of, any Federal or state statute,  rule, or
regulation,  including,  but not limited to,  requirements for annuity contracts
and retirement plans under the Internal Revenue Code and regulations  thereunder
or any state statute or regulation.


     AUL reserves the right to make certain changes in the Contracts.  Depending
                                                                       ---------
on the Contract,  AUL has the right at any time to change the Guaranteed Rate of
- ----------------
interest  credited to amounts allocated to the Fixed Account for any Participant
Accounts established on or after the effective date of the change, although once
a Participant's  Account is established,  the Guaranteed Rate may not be changed
for the duration of the Account.

     Depending on the Contract,  after the fifth anniversary of a Contract,  AUL
     --------------------------
has the right to change any annuity  tables  included in the  Contract,  but any
such change shall apply only to Participant Accounts established on or after the
effective date of such a change. AUL also has the right to change the withdrawal
charge and, within the limits  described under  "Guarantee of Certain  Charges,"
the administrative charge.


RESERVATION OF RIGHTS

     AUL  reserves  the  right to refuse to  accept  new  contributions  under a
Contract and to refuse to accept new Participants under a Contract.

Accumulation Units credited to the Contract or to the Participant's  Account, as
the case may be.  AUL will also send  statements  reflecting  transactions  in a
Participant's  Account as required by applicable law. In addition,  every person
having voting rights will receive such reports or  Prospectuses  concerning  the
Variable  Account  and the Funds as may be required by the 1940 Act and the 1933

                         YEAR 2000 READINESS DISCLOSURE

     In recent years,  the Year 2000 problem has received  extensive  publicity.
The problem arises because most computer  systems and programs were written with
dates  expressed  as a 2 digit  code.  Unless  steps are taken many  systems may
interpret the year "2000" as "1900," and date-related  computations either would
not be processed or would be processed  incorrectly.  This could have a material
and  adverse  effect  on  financial  institutions  such as banks  and  insurance
companies like AUL. To prevent this, AUL began assessing the potential impact in
early 1996 and adopted a detailed  written work plan in June,  1997 to deal with
Year 2000 issues.

     Due  to  the   complexity   of   this   issue   and   the   ever-increasing
interrelationships  of  computer  systems  in the  United  States  it  would  be
extremely  difficult  for any  company  to  state  that  it has or will  achieve
complete Year 2000 compliance or guarantee that its systems will not be affected
in any way on January 1, 2000. However, AUL currently believes that all critical
computer  systems and software  (those  systems or  software  which  would cause
great  disruption to the Company if they were  inoperable for any length of time
or if they were to generate  erroneous data) are, as of April 1, 1999, Year 2000
compliant.  Although  AUL has no reason to believe  that these steps will not be
sufficient  to avoid any  material  adverse  impact from Year 2000 issues and is
addressing   Year  2000  issues  by  using  both  internal  staff  and  external
consultants,   by  replacing  or  upgrading  hardware,   operating  systems  and
application software, by remediating current application software and by testing
software and hardware in future dated scenarios,  there can be no assurance that
the Company's efforts will be sufficient to avoid any adverse impact.  The total
effort  for all  activities  to make AUL  systems  ready  for the  year  2000 is
currently expected to amount to more than 250 person years of labor at a cost of
approximately  $19,000,000  which has been or will be expensed  against  current
operating  funds.  As of  December  1998,  $13,000,000  of this cost was already
incurred.

     As a part of its plan,  the  company  has  surveyed  its  primary  business
partners to be sure that they have taken steps to address Year 2000 issues.  AUL
will continue to monitor the status of all business partners' Year 2000 efforts.
Additionally,  a contingency  planning  effort is underway to identify  means by
which the risk  associated with potential  internal or external  failures can be
reduced. Year 2000 contingency planning also includes development of a mechanism
to identify and respond to problems that could develop and to define steps to be
taken should problems arise.

                             PERFORMANCE INFORMATION

     Performance   information  for  the  Investment  Accounts  is  shown  under
"Performance  of the  Investment  Accounts."  Performance  information  for  the
Investment  Accounts may also appear in  promotional  reports and  literature to
current or prospective  Owners or Participants  in the manner  described in this
section.  Performance  information  in  promotional  reports and  literature may
include the yield and effective yield of the Investment Account investing in the
AUL American Money Market Portfolio  ("Money Market  Investment  Account"),  the
yield of the remaining Investment Accounts,  the average annual total return and
the total return of all Investment Accounts.

     Current  yield for the Money  Market  Investment  Account  will be based on
income  received by a  hypothetical  investment  over a given 7-day period (less
expenses accrued during the period), and then "annualized" (i.e.,  assuming that
the 7-day  yield would be  received  for 52 weeks,  stated in terms of an annual
percentage  return on the  investment).  "Effective  yield" for the Money Market
Investment  Account is calculated in a manner  similar to that used to calculate
yield, but reflects the compounding effect of earnings.

     For the remaining Investment Accounts, quotations of yield will be based on
all investment income per Accumulation Unit earned during a given 30-day period,
less expenses accrued during the period ("net investment  income"),  and will be
computed by dividing net investment  income by the value of an Accumulation Unit
on the last day of the period. Quotations of average annual total return for any
Investment  Account will be expressed in terms of the average annual  compounded
rate of return on a hypothetical  investment in a Contract over a period of one,
five, and ten years (or, if less, up to the life of the Investment Account), and
will reflect the deduction of the applicable  withdrawal  charge,  the mortality
and  expense  risk  charge,  and,  if  applicable,  the  administrative  charge.
Hypothetical  quotations of average annual total return may also be shown for an
Investment  Account for periods  prior to the time that the  Investment  Account
commenced operations, based upon the performance of the mutual fund portfolio in
which that  Investment  Account  invests,  and will reflect the deduction of the
applicable  withdrawal charge, the administrative  charge, and the mortality and
expense  risk  charge as if,  and to the  extent  that,  such  charges  had been
applicable.   Quotations  of  total  return,   actual  and   hypothetical,   may
simultaneously  be  shown  that do not take  into  account  certain  contractual
charges such as the withdrawal charge and the administrative charge.

     Performance  information  for an  Investment  Account may be  compared,  in
promotional reports and literature,  to: (1) the Standard & Poor's 500 Composite
Index ("S & P 500"),  Dow Jones  Industrial  Average  ("DJIA"),  Donoghue  Money
Market  Institutional  Averages,  or other indices  measuring  performance  of a
pertinent  group of  securities  so that  investors  may  compare an  Investment
Account's  results  with  those  of a group of  securities  widely  regarded  by
investors as  representative  of the  securities  markets in general;  (2) other
variable  annuity  separate  accounts or other  investment  products  tracked by
Lipper Analytical  Services, a widely used independent research firm which ranks
mutual funds and other investment companies by overall  performance,  investment
objectives, and assets, or tracked by other ratings

<PAGE>
                                       40


services,  companies,  publications,  or persons who rank  separate  accounts or
other investment products on overall performance or other criteria;  and (3) the
Consumer  Price Index  (measure for inflation) to assess the real rate of return
from  an  investment  in  the  Contract.   Unmanaged   indices  may  assume  the
reinvestment   of  dividends  but  generally  do  not  reflect   deductions  for
administrative and management costs and expenses.

     Performance  information  for any  Investment  Account  reflects  only  the
performance of a hypothetical Contract under which Account Value is allocated to
an Investment  Account during a particular time period on which the calculations
are  based.  Performance  information  should  be  considered  in  light  of the
investment  objectives  and  policies,  characteristics,   and  quality  of  the
Portfolio  of a Fund in which the  Investment  Account  invests,  and the market
conditions  during the given time  period,  and  should not be  considered  as a
representation  of what may be achieved in the future.  For a description of the
methods used to  determine  yield and total  return in  promotional  reports and
literature  for  the  Investment  Accounts,  see  the  Statement  of  Additional
Information.

     Promotional  reports and  literature  may also  contain  other  information
including:  (1) the ranking of any Investment  Account  derived from rankings of
variable  annuity  separate  accounts or other  investment  products  tracked by
Lipper Analytical Services or by other rating services, companies, publications,
or other  persons who rank  separate  accounts or other  investment  products on
overall   performance  or  other  criteria,   (2)  the  effect  of  tax-deferred
compounding  on an  Investment  Account's  investment  returns,  or  returns  in
general, which may be illustrated by graphs, charts, or otherwise, and which may
include  a  comparison,  at  various  points  in  time,  of the  return  from an
investment  in a  Contract  (or  returns in  general)  on a  tax-deferred  basis
(assuming  one or more tax rates)  with the return on a taxable  basis,  and (3)
AUL's rating or a rating of AUL's claim-paying ability by firms that analyze and
rate  insurance  companies  and  by  nationally  recognized  statistical  rating
organizations.

                         GENERAL INFORMATION AND HISTORY

     For a general description of AUL and AUL American Unit Trust (the "Variable
Account"),  see the  section  entitled  "Information  about  AUL,  The  Variable
Account, and The Funds" in the Prospectus.

                            DISTRIBUTION OF CONTRACTS

     AUL is the Principal  Underwriter for the group variable annuity  contracts
(the  "Contracts")  described  in  the  Prospectus  and  in  this  Statement  of
Additional  Information.  AUL is  registered  with the  Securities  and Exchange
Commission  (the "SEC") as a  broker-dealer.  The Contracts are currently  being
sold in a continuous offering.  While AUL does not anticipate  discontinuing the
offering of the  Contracts,  it reserves the right to do so. The  Contracts  are
sold  by  registered  representatives  of AUL who are  also  licensed  insurance
agents.

     AUL also has sales agreements with various  broker-dealers  under which the
Contracts will be sold by registered representatives of the broker-dealers.  The
registered  representatives are required to be authorized under applicable state
regulations to sell variable annuity contracts.  The broker-dealers are required
to be  registered  with  the SEC and  members  of the  National  Association  of
Securities Dealers, Inc.

     AUL  serves as the  Principal  Underwriter  without  compensation  from the
Variable Account.

                                CUSTODY OF ASSETS

     The assets of the  Variable  Account  are held by AUL.  The assets are kept
physically  segregated  and are held separate and apart from the assets of other
separate  accounts of AUL and from AUL's General Account  assets.  AUL maintains
records of all purchases and  redemptions of shares of AUL American Series Fund,
Inc., Alger American Fund, American Century Variable  Portfolios,  Inc., Calvert
Variable Series,  Fidelity Variable Insurance  Products Fund,  Fidelity Variable
Insurance  Products Fund II, Janus Aspen  Series,  PBHG  Insurance  Series Fund,
Inc., SAFECO Resource Series Trust, and T. Rowe Price Equity Series, Inc., (each
a "Fund" and collectively the "Funds").

                   LIMITS ON CONTRIBUTIONS TO RETIREMENT PLANS

403(b) PROGRAMS

     Contributions to a 403(b) Program are excludable from a Participant's gross
income  if they do not  exceed  the  smallest  of the  limits  calculated  under
Sections 402(g), 403(b)(2), and 415 of the Internal Revenue Code. Section 402(g)
generally  limits a Participant's  salary  reduction  contributions  to a 403(b)
Program to $10,000 a year. The $10,000 limit may be reduced by salary  reduction
contributions to another type of retirement plan. A Participant with at least 15
years of service for a "qualified employer" (i.e., an educational  organization,
hospital,  home health service agency, health and welfare service agency, church
or convention or association of churches) generally may exceed the $10,000 limit
by $3,000 per year, subject to an aggregate limit of $15,000 for all years.

     Section  403(b)(2)  provides an overall  limit on Employer and  Participant
salary  reduction  contributions  that may be made to a 403(b) Program.  Section
403(b)(2)  generally  provides  that  the  maximum  amount  of  contributions  a
Participant  may exclude  from his gross  income in any taxable year is equal to
the excess, if any, of:

     (a) the amount determined by multiplying 20% of his includable compensation
by the  number of his years of  service  with his  Employer,  over

     (b) the total  amount  contributed  to  retirement  plans  sponsored by his
Employer,  including the Section 403(b)  Program,  that were excludable from his
gross income in prior years.

     Participants  employed by "qualified  employers"  may elect to have certain
alternative limitations apply.

     Section 415(c) also provides an overall limit on the amount of Employer and
Participant's  salary  reduction  contributions to a Section 403(b) Program that
will be excludable from an employee's  gross income in a given year. The Section
415(c)  limit is the  lesser  of (a)  $30,000,  or (b) 25% of the  Participant's
annual  compensation.   This  limit  will  be  reduced  if  a  Participant  also
participates in an Employee Benefit Plan maintained by a business that he or she
controls.

     The  limits  described  above do not apply to  amounts  "rolled  over" from
another Section 403(b) Program. A Participant who receives an "eligible rollover
distribution"  will be  permitted  either to roll over  such  amount to  another
Section  403(b)  Program or an IRA within 60 days of receipt or to make a direct
rollover to another  Section  403(b)  Program or an IRA without  recognition  of
income.  An  "eligible  rollover  distribution"  means  any  distribution  to  a
Participant  of all or any taxable  portion of the balance to his credit under a
Section  403(b)  Program,  other  than  a  required  minimum  distribution  to a
Participant who has reached age 70 1/2 and excluding any  distribution  which is
one of a  series  of  substantially  equal  payments  made  (1)  over  the  life
expectancy of the Participant or his beneficiary or (2) over a specified  period
of 10 years or more. Provisions of the Internal Revenue Code require that 20% of
every  eligible  rollover  distribution  that  is not  directly  rolled  over be
withheld by the payor for federal income taxes.

408 PROGRAMS

     Contributions to the individual retirement account of a Participant under a
408 Program that is described in Section 408(c) of the Internal Revenue Code are
subject to the limits

                                       3
<PAGE>

on contributions to individual  retirement  accounts under Section 219(b) of the
Internal  Revenue Code.  Under Section 219(b) of the Code,  contributions  to an
individual  retirement  account  are limited to the lesser of $2,000 per year or
the Participant's annual compensation.  For tax years beginning after 1996, if a
married  couple files a joint  return,  each spouse may, in a great  majority of
cases,  make  contributions to his or her IRA up to the $2,000 limit. The extent
to which a  Participant  may deduct  contributions  to this type of 408  Program
depends on his or her  spouse's  gross  income for the year and  whether  either
participate in another employer-sponsored retirement plan.

     Contributions  to a 408 Program that is a simplified  employee pension plan
are subject to limits under Section 402(h) of the Internal Revenue Code. Section
402(h) currently limits Employer  contributions and Participant salary reduction
contributions (if permitted) to a simplified employee pension plan to the lesser
of (a) 15% of the Participant's  compensation,  or (b) $30,000. Salary reduction
contributions, if any, are subject to additional annual limits.


457 PROGRAMS

     Deferrals by a  Participant  to a 457 Program  generally  are limited under
Section  457(b) of the Internal  Revenue Code to the lesser of (a) $8,000 or (b)
33  1/3%  of the  Participant's  includable  compensation.  If  the  Participant
participates  in  more  than  one 457  Program,  the  $8,000  limit  applies  to
contributions to all such programs. The $8,000 limit is reduced by the amount of
any salary reduction  contribution the Participant makes to a 403(b) Program,  a
408  Program,  or an  Employee  Benefit  Program.  The Section  457(b)  limit is
increased during the last three years ending before the Participant  reaches his
normal  retirement  age under the 457  Program.  Effective  January 1, 1997, the
limit on deferrals became indexed in $500 increments.

EMPLOYEE BENEFIT PLANS

     The applicable  annual limits on  contributions to an Employee Benefit Plan
depend upon the type of plan. Total  contributions on behalf of a Participant to
all defined  contribution  plans  maintained  by an Employer  are limited  under
Section 415(c) of the Internal Revenue Code to the lesser of (a) $30,000, or (b)
25% of a Participant's annual compensation.  Salary reduction contributions to a
cash-or-deferred  arrangement  under  a  profit  sharing  plan  are  subject  to
additional  annual limits.  Contributions  to a defined benefit pension plan are
actuarially  determined based upon the amount of benefits the Participants  will
receive under the plan formula.  The maximum annual benefit any  Participant may
receive under an Employer's defined benefit plan is limited under Section 415(b)

                             INDEPENDENT ACCOUNTANTS

     PricewaterhouseCoopers  LLP, One  American  Square,  Indianapolis,  Indiana
46282,  independent  accountants,   performs  certain  accounting  and  auditing
services for AUL and performs similar services for the Variable Account. The AUL
financial  statements included in this Statement of Additional  Information have
been audited to the extent and for the periods indicated in their report thereon
and its internal accounting controls have been reviewed.


                             PERFORMANCE INFORMATION

     Performance  information  for  the  Investment  Accounts  is  shown  in the
prospectus  under   "Performance  of  the  Investment   Accounts."   Performance
information for the Investment  Accounts may also appear in promotional  reports
and literature to current or prospective  Owners or  Participants  in the manner
described in this section.  Performance  information in promotional  reports and
literature may include the yield and effective  yield of the Investment  Account
investing in the AUL American Money Market Portfolio  ("Money Market  Investment
Account"),  the yield of the remaining Investment  Accounts,  the average annual
total return and the total return of all Investment Accounts.

     Current yield for the Money Market Investment  Account will be based on the
change in the value of a hypothetical  investment (exclusive of capital charges)
over  a  particular  7-day  period,  less a pro  rata  share  of the  Investment
Account's expenses accrued over that period (the "base period"), and stated as a
percentage  of the  investment at the start of the base period (the "base period
return").  The base period return is then  annualized by  multiplying  by 365/7,
with the resulting  yield figures  carried to at least the nearest  hundredth of
one percent.

     Calculation of "effective  yield" begins with the same "base period return"
used in the  calculation  of yield,  which is then  annualized to reflect weekly
compounding pursuant to the following formula:

Effective Yield = [(Base Period Return + 1)**365/7] - 1

     For the 7-day period  ending  December 31, 1998,  the current yield for the
AUL Money  Market  Investment  Account was 4.2184% and the  effective  yield was
4.3068%.

     Quotations of yield for the remaining  Investment Accounts will be based on
all investment  income per Accumulation  Unit earned during a particular  30-day
period, less expenses accrued during the period ("net investment  income"),  and
will  be  computed  by  dividing  net  investment  income  by the  value  of the
Accumulation  Unit on the last day of the  period,  according  to the  following
formula:

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

                                       4
<PAGE>


where a = net  investment  income  earned  during  the  period by the  Portfolio
attributable to shares owned by the Investment Account,

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

     c = the average daily number of Accumulation  Units outstanding  during the
period that were entitled to receive dividends, and

     d = the value (maximum offering period) per  Accumulation  Unit on the last
day of the period.

For the one year period ending  December 31, 1998,  the yield for the Investment
Accounts  corresponding  to the Portfolios of the AUL American Series Fund, Inc.
was 0.24%  for the  Equity  Investment  Account, 3.90%  for the Bond  Investment
Account,  1.65% for the Managed Investment  Account,  and 0.27% for the Tactical
Asset Allocation  Account.  The LifeStyle  Investment Accounts consisting of the
Conservative,  Moderate and Aggressive  Investor  Investment  Accounts commenced
operations  May 1, 1998,  and therefore has not been in operation for a one year
period.

     Quotations of average annual total return for any  Investment  Account will
be  expressed  in terms of the  average  annual  compounded  rate of return of a
hypothetical  investment in a Contract over a period of one, five, and ten years
(or, if less, up to the life of the Investment Account),  calculated pursuant to
the  following  formula:  P(1 + T)**n = ERV  (where P = a  hypothetical  initial
payment of $1,000, T = the average annual total return, n = the number of years,
and ERV = the ending  redeemable value of a hypothetical  $1,000 payment made at
the beginning of the period).  Hypothetical  quotations of average  annual total
return may also be shown for an Investment Account for periods prior to the time
that the Investment  Account commenced  operations based upon the performance of
the mutual fund portfolio in which that Investment Account invests,  as adjusted
for applicable  charges.  All total return figures  reflect the deduction of the
applicable  withdrawal charge, the administrative  charge, and the mortality and
expense risk charge.  Quotations of total return,  actual and hypothetical,  may
simultaneously  be  shown  that do not take  into  account  certain  contractual
charges  such  as the  withdrawal  charge  and  the  administrative  charge  and
quotations of total return may reflect other periods of time.

     The average  annual total return is  calculated  from the actual  inception
date of the AUL American  Investment Accounts and from the inception date of the
corresponding  mutual  funds  for  all of the  other  Investment  Accounts.  The
reported  performance  is,  therefore,  hypothetical  to the  extent and for the
periods that the Investment Accounts have not been in existence and reflects the
performance that such Investment  Accounts would have achieved had they invested
in the  corresponding  Mutual Funds for those  periods.  For the periods that an
Investment  Account has actually been in  existence,  however,  the  performance
represents  actual and not hypothetical  performance.  The average annual return
that the Investment  Accounts  achieved for the one year, three year, the lessor
of five years or since  inception,  five year,  the lesser of ten years or since
inception  and the  cumulative  return for 10 years or since  inception  for the
periods ending December 31, 1998 may be found in the Prospectus.

     Performance  information  for an  Investment  Account may be  compared,  in
promotional reports and literature,  to: (1) the Standard & Poor's 500 Composite
Index ("S&P 500"), Dow Jones Industrial Average ("DJIA"),  Donoghue Money Market
Institutional Averages, or other indices that measure performance of a pertinent
group of  securities  so that  investors  may  compare an  Investment  Account's
results  with those of a group of  securities  widely  regarded by  investors as
representative  of the  securities  markets  in  general;  (2)  other  groups of
variable  annuity  separate  accounts or other  investment  products  tracked by
Lipper Analytical  Services, a widely used independent research firm which ranks
mutual funds and other investment companies by overall  performance,  investment
objectives, and assets, or tracked by other services,  companies,  publications,
or persons who rank such  investment  companies on overall  performance or other
criteria; and (3) the Consumer Price Index (measure for inflation) to assess the
real rate of return from an investment in the  Contract.  Unmanaged  indices may
assume the reinvestment of dividends but generally do not reflect deductions for
administrative and management costs and expenses.

     Performance  information  for any  Investment  Account  reflects  only  the
performance of a hypothetical Contract under which a Participant's Account Value
is allocated to an Investment  Account during a particular  time period on which
the  calculations  are based.  Performance  information  should be considered in
light of the investment objectives and policies,  characteristics and quality of
the  Portfolio of the Funds in which the  Investment  Account  invests,  and the
market conditions during the given time period,  and should not be considered as
a representation of what may be achieved in the future.

     Promotional  reports and  literature  may also  contain  other  information
including  (1) the ranking of any  Investment  Account  derived from rankings of
variable  annuity  separate  accounts or other  investment  products  tracked by
Lipper Analytical Services or by other rating services, companies, publications,
or other  persons who rank  separate  accounts or other  investment  products on
overall   performance  or  other  criteria;   (2)  the  effect  of  tax-deferred
compounding  on an  Investment  Account's  investment  returns,  or  returns  in
general, which may be illustrated by graphs, charts, or otherwise, and which may
include  a  comparison,  at  various  points  in  time,  of the  return  from an
investment  in a  Contract  (or  returns in  general)  on a  tax-deferred  basis
(assuming  one or more tax rates)  with the return on a taxable  basis;  and (3)
AUL's rating or a rating of AUL's claim-paying ability by firms that analyze and
rate  insurance  companies  and  by  nationally  recognized  statistical  rating
organizations.

Report of Independent Accountants
To the Board of Directors
American United Life Insurance Company(R)
Indianapolis, Indiana


In our opinion, the accompanying combined balance sheet and the related combined
statements of operations, policyholders' surplus, and cash flows present fairly,
in all  material  respects,  the  financial  position  of  American  United Life
Insurance  Company(R)  and affiliates  (the  "Company") at December 31, 1998 and
1997,  and the results of their  operations  and their cash flows for years then
ended,  in conformity  with  generally  accepted  accounting  principles.  These
financial  statements are the  responsibility of the Company's  management;  our
responsibility  is to express an opinion on these financial  statements based on
our audits. We conducted our audits of these financial  statements in accordance
with  generally  accepted  auditing  standards  which  require  that we plan and
perform the audit to obtain  reasonable  assurance  about  whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements,  assessing the accounting  principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion  expressed
above.

1. SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations and Basis of Presentation
- ----------------------------------------------

American United Life Insurance Company(R) (AUL) is an  Indiana-domiciled  mutual
life insurance company with headquarters in Indianapolis.  AUL is licensed to do
business  in 48  states  and  the  District  of  Columbia  and is an  authorized
reinsurer in all states. AUL offers individual life and annuity products through
its career agent  distribution  system.  AUL's qualified group retirement plans,
tax deferred annuities and other non-medical group products are marketed through
independent agents and brokers, as well as career agents who are supported by 37
regional  sales  offices  located  throughout  the  country.   Life  and  pooled
reinsurance  is marketed  directly to other  insurance  companies.  In 1998, AUL
International  began operations to develop  reinsurance  partners in Central and
South America. The combined Company financial statements include the accounts of
AUL and its affiliate,  The State Life Insurance  Company (State Life),  and its
subsidiary, Equity Sales Corporation. Significant intercompany transactions have
been excluded.

The  accompanying  financial  statements  have been prepared in accordance  with
generally  accepted  accounting  principles  (GAAP).  AUL and  State  Life  file
separate financial  statements with insurance  regulatory  authorities which are
prepared on the basis of statutory  accounting practices which are significantly
different  from financial  statements  prepared in accordance  with GAAP.  These
differences are described in detail in Note 9 - Statutory Information.

The  preparation  of  financial  statements  in  conformity  with GAAP  requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities at the date of the financial statements, and the reported
amounts of revenues and expenses  during the reporting  period.  Actual  results
could differ from those estimates.

Investments
- ------------

Fixed maturity securities which may be sold to meet liquidity and other needs of
the Company are  categorized as available for sale and are stated at fair value.
Fixed maturity  securities which the Company has the positive intent and ability
to hold to  maturity  are  categorized  as  held-to-maturity  and are  stated at
amortized cost.  Equity  securities are stated at fair value.  Mortgage loans on
real estate are  carried at  amortized  cost less an  impairment  allowance  for
estimated uncollectible amounts. Real estate is reported at cost less allowances
for  depreciation.  Depreciation is provided  (straight line) over the estimated
useful lives of the related assets. Investment real estate is net of accumulated
depreciation  of $31.7  million  at  December  31,  1998 and 1997.  Depreciation
expense for investment real estate amounted to $2.4 million and $2.5 million for
1998 and 1997,  respectively.  Policy loans are carried at their unpaid balance.
Other  invested  assets  are  reported  at cost  plus the  Company's  equity  in
undistributed  net equity  since  acquisition.  Short term  investments  include
investments  with  maturities  of one-year or less and are carried at cost which
approximates market. Short term certificates of deposit and savings certificates
are  considered to be cash  equivalents.  The carrying  amount for cash and cash
equivalents approximates market.

Realized  gains and losses on sale or  maturity  of  investments  are based upon
specific  identification  of the  investments  sold and do not  include  amounts
allocable to separate accounts.  At the time a decline in value of an investment
is determined to be other than temporary, a provision for loss is recorded which
is included  in  realized  investment  gains and  losses.  Unrealized  gains and
losses, resulting from carrying available-for-sale securities at fair value, are
reported in policyholders' surplus, net of deferred taxes.

Deferred Policy Acquisition Costs
- ---------------------------------

Those costs of acquiring new business, which vary with and are primarily related
to the  production of new  business,  have been deferred to the extent that such
costs are deemed recoverable.  Such costs include commissions,  certain costs of
policy underwriting and issue and certain variable agency expenses.  These costs
are amortized with interest as follows:

     For  participating  whole life  insurance  products,  over the lesser of 30
     years or the  lifetime of the policy in  relation  to the present  value of
     estimated   gross  margins  from  expenses,   investments   and  mortality,
     discounted using the expected investment yield.

     For universal life-type policies and investment contracts,  over the lesser
     of the lifetime of the policy or 30 years for life policies or 20 years for
     other policies in relation to the present value of estimated  gross profits
     from  surrender  charges and  investment,  mortality  and expense  margins,
     discounted using the interest rate credited to the policy.

     For term life insurance  products and life reinsurance  policies,  over the
     lesser of the benefit period or 30 years for term life or 20 years for life
     reinsurance policies in relation to the ratio of anticipated annual premium
     revenue  to  the  anticipated   total  premium  revenue,   using  the  same
     assumptions used in calculating policy benefits.

     For  miscellaneous  group life and  individual  and group health  policies,
     straight line over the expected life of the policy.

     For credit  insurance  policies,  the deferred  acquisition cost balance is
     primarily equal to the unearned premium reserve  multiplied by the ratio of
     deferrable commissions to premiums written.

                                       10

                   NOTES TO FINANCIAL STATEMENTS (continued)

Recoverability of the unamortized  balance of deferred policy  acquisition costs
is evaluated regularly. For universal life-type contracts,  investment contracts
and participating whole life policies, the accumulated  amortization is adjusted
(increased or decreased)  whenever  there is a material  change in the estimated
gross profits or gross margins  expected over the life of a block of business in
order to maintain a constant  relationship  between cumulative  amortization and
the present value of gross profits or gross margins.  For most other  contracts,
the  unamortized  asset  balance is reduced by a charge to income  only when the
present  value of future  cash  flows,  net of the  policy  liabilities,  is not
sufficient to cover such asset balance.

Assets Held in Separate Accounts
- --------------------------------

Separate  accounts  are  funds on which  investment  income  and gains or losses
accrue  directly to certain  policies,  primarily  variable  annuity  contracts,
equity-based  pension  and profit  sharing  plans and  variable  universal  life
policies. The assets of these accounts are legally segregated, and are valued at
fair  value.  The  related  liabilities  are  recorded  at amounts  equal to the
underlying  assets;  the  fair  value  of  these  liabilities  is equal to their
carrying amount.

Property and Equipment
- ----------------------

Property and  equipment  includes real estate owned and occupied by the Company.
Property and equipment is carried at cost,  net of accumulated  depreciation  of
$47.1 million and $41.6 million as of December 31, 1998 and 1997,  respectively.
The Company  provides  for  depreciation  of property  and  equipment  using the
straight-line  method over its estimated useful life.  Depreciation  expense for
1998 and 1997 was $8.8 million and $7.6 million, respectively.

Premium Revenue and Benefits to Policyholders
- ---------------------------------------------

The premiums and benefits for whole life and term insurance products and certain
annuities  with  life   contingencies   (immediate   annuities)  are  fixed  and
guaranteed.  Such  premiums are  recognized as premium  revenue when due.  Group
insurance  premiums are  recognized  as premium  revenue over the time period to
which the premiums  relate.  Benefits and  expenses are  associated  with earned
premiums  so as to  result  in  recognition  of  profits  over  the  life of the
contracts.  This  association  is  accomplished  by means of the  provision  for
liabilities for future policy  benefits and the  amortization of deferred policy
acquisition costs.

Universal  life policies and  investment  contracts are policies with terms that
are not fixed and guaranteed. The terms that may be changed could include one or
more of the amounts assessed the policyholder, premiums paid by the policyholder
or  interest  accrued to  policyholder  balances.  The  amounts  collected  from
policyholders  for  these  policies  are  considered  deposits,   and  only  the
deductions during the period for cost of insurance,  policy  administration  and
surrenders are included in revenue.  Policy benefits and claims that are charged
to expense include interest credited to contracts and benefit claims incurred in
the period in excess of related policy account balances.

Reserves for Future Policy and Contract Benefits
- ------------------------------------------------

Liabilities for future policy benefits for participating whole life policies are
calculated using the net level premium method and assumptions as to interest and
mortality.  The  interest  rate  is the  dividend  fund  interest  rate  and the
mortality rates are those guaranteed in the calculation of cash surrender values
described in the contract.  Liabilities for future policy benefits for term life
insurance  and life  reinsurance  policies  are  calculated  using the net level
premium  method  and  assumptions  as  to  investment   yields,   mortality  and
withdrawals.  The  assumptions  are based on projections of past  experience and
include  provisions for possible  unfavorable  deviation.  These assumptions are
made at the time the contract is issued.  Liabilities for future policy benefits
on universal life and investment contracts consist principally of policy account
values plus  certain  deferred  policy fees which are  amortized  using the same
assumptions and factors used to amortize the deferred policy  acquisition costs.
If the  future  benefits  on  investment  contracts  are  guaranteed  (immediate
annuities  with  benefits  paid for a period  certain) the  liability for future
benefits is the present value of such  guaranteed  benefits.  Claim  liabilities
include  provisions  for  reported  claims  and  estimates  based on  historical
experience for claims incurred but not reported.

Income Taxes
- ------------

The provision for income taxes includes amounts  currently  payable and deferred
income  taxes  resulting  from  the  temporary  differences  in the  assets  and
liabilities determined on a tax and financial reporting basis.

Net realized  investment  gains and (losses)  include write downs and changes in
the  reserve for losses on mortgage  loans and  foreclosed  real estate of $(.1)
million and $(1.3)  million for 1998 and 1997,  respectively.  Proceeds from the
sales,  maturities or calls of investments in fixed  maturities  during 1998 and
1997 were approximately $850.5 million and $576.3 million,  respectively.  Gross
gains of $14.9  million and $11.6  million,  and gross losses of $.6 million and
$1.3  million  were  realized  in 1998 and 1997,  respectively.  The  changes in
unrealized  appreciation  of fixed  maturities  amounted to  approximately  $7.2
million and $39.9 million in 1998 and 1997, respectively.

At December  31, 1998,  the  unrealized  appreciation  on equity  securities  of
approximately  $2.3 million is comprised of $3.8 million in unrealized gains and
$1.5  million  of  unrealized   losses  and  has  been  reflected   directly  in
policyholders'  surplus.  The change in the  unrealized  appreciation  of equity
securities  amounted  to  approximately  $.1 million and $.9 million in 1998 and
1997, respectively.

The Company  maintains a  diversified  mortgage  loan  portfolio  and  exercises
internal limits on concentrations of loans by geographic area, industry, use and
individual mortgagor. At December 31, 1998, the largest geographic concentration
of  commercial  mortgage  loans was in Indiana,  California  and  Florida  where
approximately 31% of the portfolio was invested.  A total of 40% of the mortgage
loans  have  been  issued on retail  properties,  primarily  backed by long term
leases or guarantees from strong credits.

The Company has outstanding  mortgage loan  commitments at December 31, 1998, of
approximately  $100.3  million.  As of December 31, 1998,  the carrying value of
investments that produced no income for the previous twelve month period was $.2

4. Employees' and Agents' Benefit Plans:
- ----------------------------------------

The  Company  has  a  noncontributory  defined  benefit  pension  plan  covering
substantially all employees. Company contributions to the employee plan are made
periodically  in an amount between the minimum ERISA required  contribution  and
the  maximum   tax-deductible   contribution.   Such  amounts  are  expensed  as
contributed.  Contributions  made to the Plan were $2.1 million in 1998 and $2.8
million in 1997.

The following  benefit  information for the employees'  defined benefit plan was
determined   by   independent   actuaries  as  of  January  1,  1998  and  1997,
respectively, the most recent actuarial valuation dates:

                                         1998    (in millions)   1997
- --------------------------------------------------------------------------------
Actuarial present value of
  accumulated benefits for the
  employees' defined benefit plan       $33.6                   $28.1
Fair value of plan assets                49.6                    39.7
- --------------------------------------------------------------------------------
Funded status                           $16.0                   $11.6
- --------------------------------------------------------------------------------
Net periodic pension cost              $  2.1                  $  2.0
- --------------------------------------------------------------------------------


The assumed  discount rate was 7.17% and 7.36% for 1998 and 1997,  respectively.
For both 1998 and 1997, the expected return on plan assets was 8.0% and the rate
of  compensation  increase  assumed was 6%.  Benefits  paid out of the Plan were
approximately  $3.1 million in 1998 and $2.6 million in 1997.

The   Company   has  a   defined   contribution   plan  and  a   401(k)   salary
reduction/savings plan for employees. Quarterly contributions covering employees
who have  completed one full calendar year of service are made by the Company in
amounts based upon the Company's financial results. Company contributions to the
plan during 1998 and 1997 were $1.7 million and $1.5 million, respectively.

The Company has a defined  contribution  pension plan and a 401(k) plan covering
substantially all of the agents,  except general agents.  Contributions of 3% to
4 1/2% of defined commissions  (plus 3% to 41/2% for commissions over the Social
Security wage base) are made to the pension plan. An additional  contribution of
3% of  defined  commissions  is made to a  401(k)  plan.  Company  contributions
expensed  for  these  plans  for 1998  and  1997  were  $257,000  and  $268,000,
respectively.

The funds for all plans are held by the Company under deposit administration and
group annuity contracts.

The  Company  also  provides  certain  health care and life  insurance  benefits
(postretirement  benefits) for retired employees and certain agents  (retirees).
Employees  and agents  with at least 10 years of plan  participation  may become
eligible for such  benefits if they reach  retirement  age while working for the
Company.

Accrued postretirement benefits as of December 31:     1998 (in millions) 1997
================================================================================
Accumulated postretirement benefit obligation           $9.5              $9.3
Net postretirement benefit cost                          1.2               1.0
Company contributions                                     .7                .7
- --------------------------------------------------------------------------------

There are no  specific  plan  assets for this  postretirement  liablility  as of
December 31, 1998 and 1997.  Claims incurred for benefits were funded by company
contributions.

The assumed  discount rate used in determining  the  accumulated  postretirement
benefit was 7.00% and the assumed  health care cost trend rate was 10% graded to
5% until 2004.  Compensation rates were assumed to increase 6% at each year end.
The health  coverage  for  retirees 65 and over is capped in the year 2000.  The
health care cost trend rate assumption has an effect on the amounts reported. An
increase in the assumed  health  care cost trend rates by one  percentage  point
would increase the accumulated  postretirement benefit obligation as of December
31, 1998, by $152,000 and increase the accumulated  postretirement  benefit cost
for 1998 by $16,000.

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

Federal  income  taxes paid were $10.6  million  and $28.6  million for 1998 and
1997, respectively.

6. Reinsurance:
- ---------------

The Company is a party to various reinsurance  contracts under which it receives
premiums as a reinsurer and reimburses the ceding  companies for portions of the
claims  incurred.  At December 31, 1998 and 1997, life  reinsurance  assumed was
approximately 74% and 71%, respectively, of life insurance in force.

For individual life policies, the Company cedes the portion of the total risk in
excess of $1,500,000.  For other policies,  the Company has established  various
limits  of  coverage  it will  retain  on any one  policyholder  and  cedes  the
remainder of such coverage.

Certain statistical data with respect to reinsurance follows:

for years ended December 31                             1998             1997
- --------------------------------------------------------------------------------
Direct statutory premiums                              $374.1           $369.4
Reinsurance assumed                                     329.7            253.9
Reinsurance ceded                                       150.2            132.3
- --------------------------------------------------------------------------------
         Net premiums                                   553.6            491.0
- --------------------------------------------------------------------------------
         Reinsurance recoveries                        $146.4         $  103.4

The Company  accounts for all  reinsurance  agreements  as transfers of risk. If
companies  to which  reinsurance  has been ceded are unable to meet  obligations
under  the  reinsurance  agreements,   the  Company  would  remain  liable.  Six
reinsurers  account for  approximately  66% of the Company's  December 31, 1998,
ceded reserves for life and accident and health insurance. The remainder of such
ceded reserves is spread among numerous reinsurers.

7. Surplus Notes and Lines of Credit:
- -------------------------------------

On February 16, 1996, the Company issued $75 million of Surplus Notes, due March
30, 2026.  Interest is payable  semi-annually on March 30, and September 30 at a
7.75% annual  rate.  Any payment of interest on or principal of the Notes may be
made only with the prior approval of the Commissioner of the Indiana  Department
of Insurance.  The Surplus Notes may not be redeemed at the option of AUL or any
holder of the Surplus  Notes.  Interest paid during 1998 was $5.8  million.  The
Company has available a $125 million committed credit facility.  No amounts have
been drawn as of December 31, 1998.

8. Commitments and Contingencies:
- ---------------------------------

Various  lawsuits have arisen in the ordinary course of the Company's  business.
In each of the matters,  the Company  believes the ultimate  resolution  of such
litigation  will not result in any  material  adverse  impact to  operations  or
financial condition of the Company.

In 1997,  AUL signed an investment  agreement with  Indianapolis  Life Insurance
Company  (Indianapolis Life) and Indianapolis Life Group of Companies (ILGroup),
a downstream holding company of Indianapolis Life, with a purpose of creating an
affiliation under a mutual holding company structure.  At December 31, 1998, AUL

Life insurance companies are required to maintain certain amounts of assets on
deposit with state regulatory authorities. Such assets had an aggregate carrying
value of $4.9 million at December 31, 1998.

10. Fair Value of Financial Instruments:
- ----------------------------------------

The disclosure of fair value information about certain financial  instruments is
based  primarily  on  quoted  market  prices.  The  fair  values  of  short-term
investments and policy loans  approximate the carrying  amounts  reported in the
balance  sheets.  Fair  values for fixed  maturity  and equity  securities,  and
surplus  notes are based on quoted  market  prices  where  available.  For fixed
maturity  securities not actively traded, fair values are estimated using values
obtained  from  independent  pricing  services,   or  in  the  case  of  private
placements,  are  estimated by  discounting  expected  future cash flows using a
current market rate applicable to the yield,  credit quality and maturity of the
investments.

The fair  value of the  aggregate  mortgage  loan  portfolio  was  estimated  by
discounting  the future cash flows using  current  rates at which  similar loans
would be made to borrowers with similar credit ratings for similar maturities.

The estimated fair values of the liabilities for policyholder  funds approximate
the  statement  values  because  interest  rates  credited  to account  balances
approximate current rates paid on similar funds and are not generally guaranteed
beyond one year. Fair values for other insurance reserves are not required to be
disclosed.  However, the estimated fair values for all insurance liabilities are
taken into  consideration in the Company's  overall  management of interest rate
risk, which minimizes  exposure to changing  interest rates through the matching
of investment  maturities with amounts due under insurance  contracts.  The fair
values of certain financial instruments along with their corresponding  carrying
values at December 31, 1998 and 1997 follow.

Item 26. PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH REGISTRANT


American United Life Insurance  Company(R) (AUL) is a mutual  insurance  company
organized under the laws of the State of Indiana.  As a mutual company,  AUL has
no shareholders and therefore no one individual controls as much as 10% of AUL.

In accordance  with current law, it is  anticipated  that  American  United Life
Insurance  Company(R)  ("AUL") will request voting  instructions  from owners or
participants  of any  Contracts  that are funded by separate  accounts  that are
registered  investment  companies  under the Investment  Company Act of 1940 and
will vote shares in any such separate  account  attributable to the Contracts in
proportion  to the  voting  instructions  received.  AUL may vote  shares of any
Portfolio, if any, that it owns beneficially in its own discretion.

Registrant,  AUL  American  Individual  Unit Trust and AUL  American  Individual
Variable  Annuity Unit Trust are  separate  accounts of AUL,  organized  for the
purpose  of the  sale  of  group  and  individual  variable  annuity  contracts,
respectively.

AUL American  Individual  Variable Life Unit Trust is a separate account of AUL,
organized  for the purpose of the sale of  individual  variable  life  insurance
products.

American United Life Pooled Equity Fund B is a separate account of AUL organized
for the purpose of the sale of group variable annuity contracts.

AUL Equity Sales Corp. is a wholly owned subsidiary of AUL,  organized under the
laws of the State of Indiana  in 1969 as a  broker-dealer  to market  registered
variable insurance products and mutual funds.

AUL may also be  deemed to  control  State  Life  Insurance  Company(R)  ("State
Life"),  since a majority of AUL's  Directors  also serve as  Directors of State
Life.  By virtue  of an  agreement  between  AUL and State  Life,  AUL  provides

AUL owns a 20% share of the stock of  Reinsurance  Managers of  Princeton,  LLC,
("Princeton") a limited  liability  company organized under the laws of Delaware
on  July  1,  1996.   Princeton  is  a  reinsurance   intermediary  for  certain
catastrophic  or pooled risks.  AUL's  affiliation  allows it the opportunity to
participate in this reinsurance business.

AUL American Series Fund, Inc. (the "Fund") was  incorporated  under the laws of
Maryland  on  July  26,  1989  and is  registered  as an  open-end,  diversified
management  investment  company under the  Investment  Company Act of 1940. As a
"series" type of mutual Fund, the Fund issues shares of common stock relating to
separate  investment  portfolios.  Substantially  all of the Fund's  shares were
originally purchased by AUL in connection with the initial capitalization of the
Fund.  On December 31, 1998,  AUL owned 6.57% of the  outstanding  shares of the
Fund's  Equity  portfolio,   9.99%  of  the  Fund's  Tactical  Asset  Allocation
Portfolio,  81.97% of the Fund's Conservative Investor Portfolio,  75.83% of the
Fund's Moderate Investor Portfolio, and 77.61% of the Fund's Aggressive Investor
Portfolio.  Therefore,  AUL would be able to control any issue  submitted to the
vote of shareholders of the LifeStyle Portfolios.

INDIANAPOLIS  LIFE INSURANCE  COMPANY is an Indiana  domestic  mutual  insurance
company  whose  principal  business  is the sale of life  insurance  and annuity
contracts. On November 3, 1997 AUL entered into an Agreement to Affiliate and an
Investment   Agreement   with   Indianapolis   Life.   The   Indiana   Insurance
Commissioner's  Findings  of  Fact,  Conclusions  of Law  and  Order  was  filed
regarding AUL's  agreements with  Indianapolis  Life on December 19, 1997. Under
the agreements, AUL initially invested $27 million in Indianapolis Life's wholly
owned downstream holding company,  Indianapolis Life Group of Companies, Inc., a
portion of this  investment  occurring on December 30, 1997 and the remainder on
March 30, 1998. On June 30, 1998, AUL invested another  $4,166,000,  on December
31, 1998 AUL invested  $18,375,000,  and on March 31, 1999, AUL invested another
$4,500,000.  At the present time, AUL holds an equity interest of  approximately
33% in Indianapolis Life Group of Companies, Inc. These investments are pursuant
to the  agreements  which  also  provide,  in  part,  for  the two  insurers  to
eventually  affiliate under the same mutual holding company structure as soon as
state law permits.  Currently, that matter is pending before the Indiana General
Assembly.

PIONEER  MUTUAL  LIFE  INSURANCE  COMPANY  is a  North  Dakota  domestic  mutual
insurance  company whose  principal  business is the sale of life  insurance and
annuity  contracts.  On November 10, 1998,  AUL became a party to an  agreement,
along with  Indianapolis  Life Insurance  Company,  whereby  Pioneer Mutual will
eventually become a part of the mutual holding company structure noted above. On
March 31,  1999,  AUL  purchased a Surplus  Note  issued by Pioneer  Mutual Life
Insurance Company in the amount of $10,000,000.

Item 27. NUMBER OF CONTRACTHOLDERS

As  of  February  28,  1999,   AUL  has  issued  863   qualified   contracts  to
Contractholders who have or may invest funds in the AUL American Unit Trust.


Item 28. INDEMNIFICATION

Article IX, Section 1 of the by-laws of AUL provides as follows:

The  corporation  shall  indemnify any director or officer or former director or
officer of the corporation  against expenses actually and reasonably incurred by
him (and for  which he is not  covered  by  insurance)  in  connection  with the
defense  of any  action,  suit  or  proceeding  (unless  such  action,  suit  or
proceeding  is settled) in which he is made a party by reason of being or having
been such  director  or  officer,  except in  relation to matters as to which he
shall  be  adjudged  in  such  action,  suit or  proceeding,  to be  liable  for
negligence or misconduct in the  performance of his duties.  The corporation may
also  reimburse  any  director  or officer or former  director or officer of the
corporation for the reasonable  costs of settlement of any such action,  suit or
proceeding,  if it shall be found by a majority of the directors not involved in
the matter in controversy  (whether or not a quorum) that it was to the interest
of the  corporation  that  such  settlement  be made and that such  director  or
officer  was  not  guilty  of   negligence   or   misconduct.   Such  rights  of
indemnification  and reimbursement shall not be exclusive of any other rights to
which such director or officer may be entitled under any By-law, agreement, vote
of members or otherwise.

Insofar as indemnification  for liabilities  arising under the Securities Act of
1933 may be permitted to  directors,  officers  and  controlling  persons of the
Registrant by the Registrant  pursuant to the Fund's Articles of  Incorporation,
its By-laws or  otherwise,  the  Registrant  is aware that in the opinion of the
Securities  and Exchange  Commission,  such  indemnification  is against  public
policy as expressed in the Act, and therefore,  is  unenforceable.  In the event
that a claim  for  indemnification  against  such  liabilities  (other  than the
payment by the Registrant of expenses incurred or paid by directors, officers or
controlling  persons of the Registrant in connection with the successful defense
of any act,  suit or  proceeding)  is  asserted by such  directors,  officers or
controlling  persons  in  connection  with  the  shares  being  registered,  the
Registrant  will,  unless in the  opinion  of its  counsel  the  matter has been
settled by controlling precedent,  submit to a court of appropriate jurisdiction
the question  whether such  indemnification  by it is against  public  policy as
expressed  in the Act and will be  governed  by the final  adjudication  of such
issues.

Additional Representations:

(a)       The  Registrant and its Depositor are relying upon Rule 6c-7 under the
          Investment  Company  Act of 1940 (17 CFR  270.6c-7),  Exemptions  from
          Certain  Provisions of Sections 22(e) and 27 for  Registered  Separate

          403(b) of the Internal  Revenue Code, and the provisions of paragraphs
          (1)-(4) of this letter have been complied with.

(c)       The Registrant represents that the aggregate fees and charges deducted

          services rendered, the expenses expected to be incurred, and the risks
          assumed by the Insurance Company.

          Account on that date.

1.2  "Accumulation  Period"  means the period of time  commencing on the date on
     which a Participant's initial  Contribution is credited to the  Participant
     Account  and  terminating  on the date when  such  Participant  Account  is
     closed.

1.3  "Accumulation  Unit" means a statistical  device used to measure amounts of
     increases to, decreases from, and  accumulations in any Investment  Account
     during the Accumulation Period.

1.4  "Annuity  Commencement Date" means the first day of any month upon which an
     annuity begins under this contract. However, for any Participant, this date
     shall not be later  than the  required  beginning  date as  defined  in the
     applicable sections of the Code and Regulations issued thereunder.

1.5  "Code" means the Internal Revenue Code of l986, as amended.

1.6  "Contract  Anniversary"  means the first day of each  Contract  Year.  Each
     Contract Anniversary after the First Contract Anniversary shall be the same
     day of the same month as the day and month which is stated on the face page
     of this contract for the First Contract Anniversary.

1.7  "Contract  Quarter"  means each of the four  successive  intervals of three
     months, the sum of which corresponds to a 12-month Contract Year.

1.8  "Contract Year" means,  for the first such year, the period  beginning with
     the Contract  Date and ending on the day  immediately  preceding  the First
     Contract  Anniversary,  and for each  succeeding  Contract Year, the period
     beginning  with a Contract  Anniversary  and ending on the day  immediately
     preceding the next succeeding Contract Anniversary.

1.9  "Contributions"  means  amounts  paid to AUL from  time to time  by,  or on
     behalf  of,  Participants,  which  are  credited  to  Participant  Accounts
     hereunder.

1.10 "Current  Rates of Interest"  means each of the annual  effective  rates of
     interest  as  determined  and  declared  by AUL  from  time to time  and as
     credited  to each  interest  pocket  maintained  within the Fixed  Interest
     Account.  The Current Rates of Interest shall always be equal to or greater
     than the Guaranteed Rate of Interest.

1.11 "Excess  Contributions" means those Contributions made by, or on behalf of,
     a  Participant  which exceed the  limitations  in effect  under  applicable
     provisions of the Code and Regulations issued thereunder.

     which all or a portion  of a  Participant's  Account  Value may be held for
     accumulation at the Current Rates of Interest.
<PAGE>

     (a)  Contributions allocated, or amounts transferred, to the Fixed Interest
          Account shall be credited to the open  interest  pocket and shall earn
          interest at the Current  Rate of Interest in effect for that  interest
          pocket.  Such  Contributions or transferred  amounts,  during the time
          that the Current  Rate of  Interest  exceeds  the  Guaranteed  Rate of
          Interest,  shall  earn  interest  at  such  credited  Current  Rate of
          Interest for at least 1 year.  After such 1-year period,  AUL reserves
          the right to declare,  at any time,  a new Current Rate of Interest to
          be applied to funds held within  that  interest  pocket.  Any such new
          Current  Rate of  Interest  must  remain in effect  for that  interest
          pocket for at least 1 year.

     (b)  If AUL changes the Current Rate of Interest for new  Contributions  or
          new amounts  transferred to the Fixed Interest  Account,  the previous
          open interest  pocket shall close,  and any  Contributions  or amounts
          transferred  on or after the  effective  date of such change  shall be
          credited to a new open interest  pocket and shall earn interest at the
          new  Current  Rate of  Interest  in effect for such new open  interest
          pocket.  Therefore,  at any given time,  various  funds  credited to a
          Participant Account and allocated to the Fixed Interest Account may be
          earning interest at different  Current Rates of Interest for different
          periods of time.

1.13 "Guaranteed Rate of Interest" means interest at an annual effective rate of
     4.00%.

          in shares of the AUL American Equity Portfolio of the Mutual Fund.

     Investment  Accounts of the  Variable  Account.  AUL  reserves the right to
     provide other Investment Options under this contract at any time.

1.17 "Mutual  Fund" means the AUL  American  Series Fund,  Inc., a  diversified,
     open-end  management  investment  company  registered  under The Investment
     Company Act of l940.

     Contributions  or  for  whom   Contributions  are  made,  and  for  whom  a
     Participant Account is established.

1.23 "Variable  Account" means a separate account  established by AUL called the
     AUL American Unit Trust,  which is registered under The Investment  Company
     Act of l940 as a unit investment trust.

1.24 "Withdrawal  Charge"  means a charge taken by AUL equal to a percentage  of
     the Account Value  withdrawn  pursuant to Section 4.8, where the percentage
     varies by the number of full  years  measured  from the date a  Participant
     Account is  established  to the date the  Withdrawal  Charge is determined.
     Such percentage is as follows:

                  During
               Account Years                              Percentage

                    1-5                                        8
                    6-10                                       4
                 Thereafter                                    0

     In no event will the cumulative total of all Withdrawal Charges,  including
     those  previously  assessed against any amount withdrawn from a Participant
     Account,  exceed 9% of total  Contributions  allocated to that  Participant
     Account.

1.25 "Withdrawal Value" means a Participant's Account Value minus the applicable
     Withdrawal Charge, and minus the Participant's outstanding loan balance, if
     any, and any expense charges due on such loans.

<PAGE>

              ARTICLE 3 - CONTRIBUTIONS, INVESTMENTS, AND TRANSFERS


3.1  Amount of Contributions:

     (a)  Contributions may vary in amount and frequency;  however, they must be
          at  least  equal  to  a  minimum  annual   Contribution  of  $200  per
          Participant  in any full  Contract  Year.  AUL may change the  minimum
          annual  Contribution  acceptable  under  this  contract,  but any such
          change shall apply only to individuals  who become  Participants on or
          after the date of the change.

     (b)  Excess  Contributions  (plus gains or minus losses  thereon)  shall be
          withdrawn from a Participant  Account and returned to the  Participant
          upon   receipt  by  AUL  at  its  Home  Office  of  complete   written
          instructions  from the  Participant.  Such written  instructions  must
          include the amount to be withdrawn  and  returned,  and  certification
          that such Contributions  constitute Excess Contributions and that such
          returns  are  permitted  by  applicable  provisions  of the  Code  and
          Regulations issued  thereunder.  It shall not be the responsibility of
          AUL to determine  the existence or amount of Excess  Contributions  or
          gains or losses thereon,  or that returns of Excess  Contributions are
          permitted by  applicable  provisions of the Code and  Regulations.  In
          withdrawing and returning the  identified amount,  AUL may rely solely
          on such written instructions and certification.  Such a withdrawal and
          return of Excess Contributions shall not be subject to Section 4.8.

3.2  How Contributions Are Handled:

     (a)  When a  Contribution  is  received  at the  Home  Office,  it shall be
          credited to  Participant  Accounts  as directed in written  allocation
          instructions.

     (b)  The initial  Contribution  for a  Participant  shall be  credited  and
          allocated  to the  Participant  Account  no later  than  the  close of
          business on the second  business day of AUL after the later of (1) the
          business day that AUL receives  the initial  Contribution  at its Home
          Office, or (2) the business day that AUL receives, at its Home Office,
          the data required to establish the Participant  Account and allocation
          instructions regarding the initial Contribution.  If the data required
          to  establish  the  Participant  Account and  allocation  instructions
          regarding the initial Contribution are not received by AUL at its Home
          Office  within 5 business  days after AUL first  receives  the initial
          Contribution,  AUL  shall  return  the  initial  Contribution  to  the
          contributing  party  unless  consent  is  given to AUL to  retain  the
          initial  Contribution  until  AUL  receives  the data  and  allocation
          instructions for the Participant.  Alternatively, if the data required
          to  establish  the  Participant  Account and  allocation  instructions
          regarding the initial Contribution are not received by AUL at its Home
          Office when AUL first receives the initial Contribution, to the extent
          permitted by applicable law, AUL may allocate the initial Contribution
          to the  Money  Market  Investment  Account,  and shall  transfer  such
          amounts credited to the Money Market  Investment  Account according to
          the  applicable  allocation  instructions  upon  receipt  of the  data
          required  to  establish  the   Participant   Account  and   allocation
          instructions.

     (c)  All  Contributions  subsequent  to the initial  Contribution  shall be
          credited and  allocated  as of the close of business on the  Valuation
          Period in which AUL  receives  the  Contribution  at its Home  Office,
          provided that the  Contribution is received by 4:00 p.m. E.S.T. If the
          Contribution  is received after 4:00 p.m.  E.S.T.,  such  Contribution
          shall be deemed to be received, and shall be credited and allocated as
          of the close of business, on the next succeeding Valuation Period.

     (d)  Within any one  Participant  Account,  the amount so credited shall be
          allocated  to an  Investment  Option in  increments  of 10%,  25%,  or
          33-1/3%,  as elected by the  Participant in writing.  If no allocation
          instruction is made with respect to any Participant Account, AUL shall
          process such credits in  accordance  with the  allocation  instruction
          applicable to the immediately preceding Contribution.  If there should
          be no allocation instruction applicable to a portion of a Contribution
          other than the initial Contribution,  that amount shall be credited to
          the  Fixed  Interest   Account  until  such  time  as  an  appropriate
          allocation instruction is received, at which time such amount shall be
          withdrawn  from the Fixed Interest  Account and allocated  pursuant to
          such   instructions.   The   Participant   may  change  an  allocation
          instruction  with  respect to future  allocations  to his  Participant
          Account by giving new written  allocation  instructions  to AUL at its
          Home Office.

3.3  Addition, Deletion, or Substitution of Investments:

     (a)  AUL reserves the right,  subject to compliance with applicable law, to
          make additions to, deletions from,  substitution  for, or combinations
          of,  the  securities  that are  held by the  Variable  Account  or any
          Investment  Account or that the  Variable  Account  or any  Investment
          Account may  purchase.  AUL reserves the right to eliminate the shares
          of any of the  eligible  Portfolios  and to  substitute  shares of, or
          interests  in,  another  Portfolio  of the  Mutual  Fund,  of  another
          open-end,  registered investment company, or other investment vehicle,
          for shares  already  purchased  or to be purchased in the future under
          the contract,  if the shares of any or all eligible  Portfolios are no
          longer  available for investment,  or if, in AUL's  judgment,  further
          investment in any or all eligible Portfolios becomes  inappropriate in
          view of the purposes of the Variable  Account or the  contract.  Where
          required under  applicable  law, AUL will not substitute any shares in
          the  Variable  Account  or  any  Investment  Account  without  notice,
          Participant approval, or prior approval of the Securities and Exchange
          Commission or a state insurance  commissioner,  and without  following
          the  filing  or  other  procedures  established  by  applicable  state
          insurance  regulators.  Nothing  contained  herein  shall  prevent the
          Variable  Account from purchasing other securities for other series or
          classes of contracts, or from effecting a conversion between series or
          classes of  contracts  on the basis of requests  made by a majority of
          participants or as permitted by federal law.

     (b)  AUL reserves the right to establish  additional  Investment  Accounts,
          each of which would invest in a new  Portfolio of the Mutual Fund,  or
          in  other  securities,  investment  vehicles,  or  shares  of  another
          diversified open-end management  investment company or series thereof.
          AUL reserves the right to  eliminate  or combine  existing  Investment
          Accounts if, in its sole  discretion,  marketing,  tax, or  investment
          conditions  so warrant.  AUL also  reserves the right to provide other
          Investment  Options  under this  contract at any time.  Subject to any
          required  regulatory  approvals,  AUL  reserves  the right to transfer
          assets from any Investment  Account to another separate account of AUL
          or Investment Account.

     (c)  In the  event  of  any  such  substitution  or  change,  AUL  may,  by
          appropriate  amendment,  make such changes in this  contract as may be
          necessary or appropriate to reflect such  substitution  or change.  If
          deemed  by AUL to be in the best  interests  of  persons  or  entities
          having voting rights under this contract,  the Variable Account may be
          operated  as a  management  investment  company  under The  Investment
          Company  Act of 1940 or any other  form  permitted  by law,  it may be
          deregistered  in the event  such  registration  is no longer  required
          under The  Investment  Company Act of 1940, or it may be combined with
          other separate accounts of AUL or an affiliate  thereof.  AUL may take
          such action as is necessary to comply with,  or to obtain,  exemptions
          from  the  Securities  and  Exchange  Commission  with  regard  to the
          Variable Account.  Subject to compliance with applicable law, AUL also
          may  combine  one or more  Investment  Accounts  and may  establish  a
          committee,  board, or other group to manage one or more aspects of the
          operation of the Variable Account.

3.4  Transfers:

     (a)  Subject to the  limitations of Section 3.5, the Participant may direct
          AUL  at its  Home  Office  to  transfer  the  amounts  credited  to an
          Investment   Option  to  any  other   Investment   Option  during  the
          Accumulation  Period.  For any transfer  from an  Investment  Account,
          Accumulation  Units shall be valued as of the close of business on the
          Valuation Date that AUL receives the Participant's direction, provided
          that AUL receives such direction by 4:00 p.m. E.S.T. on that Valuation
          Date.  If such  direction  is received  after 4:00 p.m.  E.S.T.,  such
          transfer  shall be  effective  as of the close of business on the next
          succeeding Valuation Date.

     (b)  AUL shall make the transfer as requested by the  Participant  within 7
          days from the date a proper  request  is  received  by AUL at its Home
          Office,  except  as AUL may  be  permitted to defer  such  payment  of
          amounts  withdrawn  from  the  Variable  Account  in  accordance  with
          appropriate  provisions of the federal  securities  laws. AUL reserves
          the right to defer a  transfer  of  amounts  from the  Fixed  Interest
          Account  for a period of 6 months  after  AUL  receives  the  transfer
          request at its Home Office.

     (c)  All  transfers  from the  Fixed  Interest  Account  to any  Investment
          Account shall be made on a first-in/first-out accounting basis.

3.5  Limitations on Transfers:

     (a)  The  Participant  may  not  direct  a  transfer  with  regard  to  his
          Participant Account's share of any Investment Option in an amount less
          than $500 or the  Participant  Account's  entire  share,  if less than
          $500. If such a transfer reduces the Participant  Account's  remaining
          share of an Investment  Option to less than $500, the entire remaining
          share shall also be transferred.

     (b)  Amounts  transferred  from the Fixed  Interest  Account on behalf of a
          Participant  during  any  Contract  Year  shall not  exceed 20% of the
          Participant  Account's share of the Fixed Interest Account  determined
          as  of  the  last  Contract  Anniversary  preceding  the  request  for
          transfer,  or the  Participant  Account's  entire  share of the  Fixed
          Interest  Account  if such  share  would be less than  $500  after the
          transfer.
<PAGE>
     (c)  Amounts under this  contract  which have been  transferred  from other
          group annuity contracts,  whether issued by AUL or otherwise, shall be

          number and frequency of transfers,  to suspend the transfer  privilege
          provided  in  Sections  3.4 and  3.5,  and to  impose  a  charge  on a
          transfer.

     (e)  Where a  Participant  has  outstanding  loans under this  contract,  a

          be permitted only to the extent that the remaining Withdrawal Value of
          the  Participant  held in the Fixed Interest  Account equals twice the
          total of the Participant's outstanding loans under this contract.

                         ARTICLE 4 - BENEFITS AND LOANS


4.1  Election of Annuity Options: At the written request of the Participant, AUL
     shall apply all or a portion of the Account Value  (subject to Section 6.5,
     and minus any  outstanding  loan balance of the  Participant and any unpaid
     expense charges on such loans) of the  Participant  Account for the purpose
     of providing a fixed payment annuity.  Upon receipt of such request, AUL is
     hereby authorized by such Participant to value and transfer the Participant
     Account's share of the Variable Account to the Fixed Interest Account as of
     the date that AUL receives  such written  request at its Home Office.  Such
     transferred  amounts shall be held in the Fixed Interest  Account until the
     Participant's  Annuity  Commencement  Date. The  Participant  request shall
     include certification as to the purpose for the annuity and the election of
     one of the following  annuity  options.  The amount of the annuity shall be
     computed  from the  Table of  Immediate  Annuities  then  included  in this
     contract, except as provided under Section 4.4.

4.2  Annuity Options:

     (a)  Life  Annuity.  The monthly  annuity shall be payable to the annuitant
          for as long as the  annuitant  lives,  and  shall  end  with  the last
          monthly payment before the death of the annuitant.

     (b)  Certain and Life Annuity.  The monthly annuity shall be payable to the
          annuitant for as long as the annuitant  lives.  If the annuitant  dies
          before  receiving  payments  for the certain  period (5, 10, 15, or 20
          years, as specified in the election),  any remaining  payments for the
          balance  of the  certain  period  shall  be  paid  to the  annuitant's
          beneficiary.

     (c)  Survivorship  Annuity.  The  monthly  annuity  shall be payable to the
          annuitant for as long as the annuitant  lives.  After the death of the
          annuitant,  a portion (all, 2/3, or 1/2, as specified in the election)
          of the  annuitant's  monthly  annuity shall be paid to the  contingent
          annuitant  named  in the  election  for  as  long  as  the  contingent
          annuitant lives. An election of this option is automatically cancelled
          if either the Participant or the contingent  annuitant dies before the
          Annuity Commencement Date.

     (d)  Installment Refund Life Annuity.  The monthly annuity shall be payable
          to the  annuitant for as long as the  annuitant  lives,  and shall end
          with the last monthly  payment before the death of the annuitant.  If,
          at the  death  of the  annuitant,  the  sum  of the  monthly  payments
          previously  received  is less than the amount  applied to provide  the
          annuity,  monthly  payments of the same amount  shall  continue to the
          annuitant's  beneficiary  until  the  total  of the  monthly  payments
          received equals such amount.

     (e)  Fixed  Period.  The monthly  annuity shall be payable to the annuitant
          for a fixed  period  of time  (not  less than 5 years nor more than 30
          years,  as  specified  in  the  election).  If,  at the  death  of the
          annuitant,  payments  have been made for less than the selected  fixed
          period, monthly annuity payments to the annuitant's  beneficiary shall
          be continued during the remainder of such fixed period.

     (f)  Any other  options  made  available  by AUL at the time a  Participant
          exercises his option to elect an annuity.



     If the annuity option selected  is not included  in the  attached  Table of
     Immediate Annuities,  the amount of monthly annuity shall be based on rates
     determined in the same manner as those found in the Table.

     If no annuity option election for a Participant has been received by AUL at
     its Home  Office at least 30 days prior to the Annuity  Commencement  Date,
     the Account Value (subject to Section 6.5, and minus any  outstanding  loan
     balance of the Participant and any unpaid expense charges on such loans) of
     his  Participant  Account  shall be  applied  under  (b) above as a 10 Year
     Certain and Life Annuity.  AUL must receive  written  notification  of such
     Annuity  Commencement Date, written designation of the contingent annuitant
     or  beneficiary,  and any  election  forms  needed in  connection  with any
     annuity option provided in this Section.

     In no event shall any  option  elected  provide  annuity  benefits  to  the
     Participant or to the Participant  and the contingent annuitant which would
     extend for a certain period beyond the life expectancy of such  Participant
     or the  joint  life  expectancy  of such  Participant  and such  contingent
     annuitant as determined on the Annuity Commencement Date.

4.3  Guaranteed Rate of Interest:  The retirement  annuity  options  provided in
     this Article and illustrated  in the attached Table of Immediate  Annuities
     are based on a guaranteed interest rate of 4.00% compounded annually.

4.4  Alternate Nonparticipating Retirement Annuity: Any annuity elected shall be
     provided at whatever  current  single  premium  nonparticipating  immediate
     annuity rates are available  under this class of group annuity  contract if
     such rates produce a higher  income than that  provided  under the Table of
     Immediate Annuities provided in this contract.

4.5  Minimum  Payments:  If the total  Account  Value is less than $2,000,  such
     value  (minus any  outstanding  loan  balances of the  Participant  and any
     unpaid  expense  charges on such loans)  shall be paid in a lump sum to the
     annuitant  rather than  annuitized  under the annuity  options  provided in
     Section 4.2.  Additionally,  if the monthly annuity is less than AUL's then
     current established  minimum,  AUL reserves the right to make payments on a
     less frequent basis.

4.6  Due Proof of Date of Birth and Survival:  Before commencing  payments under
     any annuity,  AUL may require  proof of the date of birth of any  annuitant
     and may require due proof that any  annuitant is living  before the payment
     of each or any installment under the option.

4.7  Death Benefits:

     (a)  Upon   receipt  of  written   instructions   from  the   Participant's
          beneficiary  (or, if  applicable,  the  secondary  beneficiary  of the
          Participant)  and  of  due  proof  of  the   Participant's   (and,  if
          applicable, the beneficiary's) death during the Accumulation Period at
          its Home  Office,  AUL  shall  apply  the  Account  Value  (minus  the
          Participant's  outstanding  loan balance,  if any, under this contract
          and any unpaid expense  charges due on such loans) of the  Participant
          Account  for the  purpose  of  providing  a death  benefit.  The death
          benefit shall be paid to the beneficiary  last properly  designated in
          writing to AUL at its Home Office by the Participant,  or, if there is
          no  designated  beneficiary  living  on the date of the  Participant's
          death, to the  Participant's  estate.  If any  beneficiary  dies while
          receiving
<PAGE>

          payments and no beneficiary is designated  to  receive  any  remaining
          payments,  such  remaining  payments  shall  be made  to the  deceased
          beneficiary's estate.

     (b)  The  Account  Value  to be  applied  pursuant  to (a)  above  shall be
          determined  as of the  close  of  business  on the  later  of (1)  the
          Valuation Date that AUL receives such written

     If the annuity option selected  is not included  in the  attached  Table of
     Immediate Annuities,  the amount of monthly annuity shall be based on rates
     determined in the same manner as those found in the Table.

     If no annuity option election for a Participant has been received by AUL at
     its Home  Office at least 30 days prior to the Annuity  Commencement  Date,
     the Account Value (subject to Section 6.5, and minus any  outstanding  loan
     balance of the Participant and any unpaid expense charges on such loans) of
     his  Participant  Account  shall be  applied  under  (b) above as a 10 Year
     Certain and Life Annuity.  AUL must receive  written  notification  of such
     Annuity  Commencement Date, written designation of the contingent annuitant
     or  beneficiary,  and any  election  forms  needed in  connection  with any
     annuity option provided in this Section.

     In no event shall any  option  elected  provide  annuity  benefits  to  the
     Participant or to the  Participant and the contingent annuitant which would
     extend for a certain period beyond the life expectancy of such  Participant
     or the  joint  life  expectancy  of such  Participant  and such  contingent
     annuitant as determined on the Annuity Commencement Date.

4.3  Guaranteed Rate of Interest:  The retirement  annuity  options  provided in
     this Article and  illustrated in the attached Table of Immediate  Annuities
     are based on a guaranteed interest rate of 4.00% compounded annually.

4.4  Alternate Nonparticipating Retirement Annuity: Any annuity elected shall be
     provided at whatever  current  single  premium  nonparticipating  immediate
     annuity rates are available  under this class of group annuity  contract if
     such rates produce a higher  income than that  provided  under the Table of
     Immediate Annuities provided in this contract.

4.5  Minimum  Payments:  If the total  Account  Value is less than $2,000,  such
     value  (minus any  outstanding  loan  balances of the  Participant  and any
     unpaid  expense  charges on such loans)  shall be paid in a lump sum to the
     annuitant  rather than  annuitized  under the annuity  options  provided in
     Section 4.2.  Additionally,  if the proposed monthly annuity payment should
     fall below AUL's periodically adjusted minimum monthly annuity payment, AUL
     reserves   the  right  to  make   payments   on  a  less   frequent   basis
     (i.e., quarterly, semiannually,  or annually),  so that the actual  monthly
     annuity payment is equal to or greater than the established minimum level.

4.6  Due Proof of Date of Birth and Survival:  Before commencing  payments under
     any annuity,  AUL may require  proof of the date of birth of any  annuitant
     and may require due proof that any  annuitant is living  before the payment
     of each or any installment under the option.

4.7  Death Benefits:

     (a)  Upon   receipt  of  written   instructions   from  the   Participant's
          beneficiary  (or, if  applicable,  the  secondary  beneficiary  of the
          Participant)  and  of  due  proof  of  the   Participant's   (and,  if
          applicable, the beneficiary's) death during the Accumulation Period at
          its Home  Office,  AUL  shall  apply  the  Account  Value  (minus  the
          Participant's  outstanding  loan balance,  if any, under this contract
          and any unpaid expense  charges due on such loans) of the  Participant
          Account  for the  purpose  of  providing  a death  benefit.  The death
          benefit shall be paid to the beneficiary  last properly  designated in
          writing to AUL at its Home Office by the Participant,  or, if there is
          no  designated  beneficiary  living  on the date of the  Participant's
          death, to the  Participant's  estate.  If any  beneficiary  dies while
          receiving  payments and no  beneficiary  is  designated to receive any
          remaining  payments,  such  remaining  payments  shall  be made to the
          deceased beneficiary's estate.

     (b)  The  Account  Value  to be  applied  pursuant  to (a)  above  shall be
          determined  as of the  close  of  business  on the  later  of (1)  the
          Valuation Date that AUL receives such written

P-12833.12 - FL

<PAGE>

          instructions at its Home Office, or (2) the Valuation  Date  that  AUL
          receives  such due proof of death at its Home  Office,  provided  that
          such written  instructions or due proof of death received on the later
          of (1) or (2)  above  are (is)  received  by 4:00  p.m. E.S.T.  If the
          written  instructions  or due proof of death  received on the later of
          (1) or (2)  above  are (is) received  after  4:00  p.m.  E.S.T.,  such
          valuation  shall  be made as of the  close  of  business  on the  next
          succeeding Valuation Date.

  (c)     (1)  The  benefit  shall  be  payable  in  accordance  with one of the
               following  provisions  as  elected  by  the  Participant  or  the
               beneficiary if the Participant did not make an election:

               (i)  The entire  Account Value to be applied shall be paid to the
                    beneficiary in a single sum or by another  elected method on
                    or before  December 31 of the calendar  year which  contains
                    the  fifth  anniversary  of the  date  of the  Participant's
                    death; or

               (ii) The benefit shall be paid as an annuity in  accordance  with
                    the Annuity  Options  shown in Section 4.2 over a period not
                    to exceed the life or life expectancy of the beneficiary. If
                    the beneficiary is not the  Participant's  surviving spouse,
                    the  annuity  must  begin on or  before  December  31 of the
                    calendar  year  immediately  following  the calendar year in
                    which  the  Participant  died.  If  the  beneficiary  is the
                    Participant's  surviving spouse,  the annuity need not begin
                    before  December  31 of  the  calendar  year  in  which  the
                    Participant would have attained age 70 1/2.

          (2)  If a Participant dies on or after his Annuity  Commencement Date,
               any interest remaining under the Annuity Option selected shall be
               paid at least as rapidly as prior to the Participant's death.

          (3)  If  payment  is to be made in a cash lump sum,  payment  shall be
               made within 7 days of the date of valuation,  as determined above
               in this  Section,  except as AUL may be  permitted  to defer such
               payment  of  amounts   derived  from  the  Variable   Account  in
               accordance with the provisions of federal  securities laws. Also,
               AUL reserves the right to defer the payment of amounts  withdrawn
               from the Fixed  Interest  Account for a period of 6 months  after
               AUL receives written instructions at its Home Office.

4.8  Withdrawal Benefits:

     (a)  Except  as stated  below,  a  Participant,  upon  submitting  a proper
          written request to AUL at its Home Office,  may direct AUL to withdraw
          all or a portion  of the  Account  Value  (subject  to the  Withdrawal
          Charge) of his Participant Account, provided that:

          (l)  any  distribution  to a  Participant  shall not  occur  until the
               Participant has:

               (i)  attained age 59 1/2; or

               (ii) terminated employment; or
<PAGE>

               (iii) become totally disabled (as defined by the Internal Revenue
                    Service); or

               (iv) experienced  a hardship (as defined by the Internal  Revenue
                    Service); or

          (2)  the amount being withdrawn is attributable to Contributions  made
               other than pursuant to a salary reduction  agreement  (within the
               meaning of Code Section 402(g)(3)(C); or

          (3)  the amount being  withdrawn is attributable to amounts held as of
               December  31, l988 under  another  Code  Section  403(b)  annuity
               contract.

          (4)  In the  case of a  hardship  withdrawal  referred  to in  (1)(iv)
               above,  any gain  credited to  Contributions  made  pursuant to a
               salary reduction agreement may not be withdrawn.

          (5)  AUL shall not be  responsible  for  determining  a  Participant's
               compliance with the requirements  above.  Any withdrawal  request
               shall include  certification as to the purpose of the withdrawal.
               The  Participant  assumes  full  responsibility  for  determining
               whether the withdrawal is permitted under applicable law. AUL may
               rely solely upon the  representations  of the Participant made in
               the withdrawal request.

     (b)  Withdrawals from a Participant Account's share of an Investment Option
          may not be made in an  amount  less  than the  smaller  of $500 or the
          Participant  Account's  entire share of the  Investment  Option.  If a
          withdrawal  reduces the  Participant  Account's share of an Investment
          Option to less than $500, such remaining share shall also be withdrawn
          (except  for  amounts   prohibited  from  being  distributed   because
          provision (a)(1) above is not met).

     (c)  A withdrawal request shall be effective as of the close of business on
          the  Valuation  Date that AUL  receives  a proper  written  withdrawal
          request at its Home Office, provided that AUL receives such request by
          4:00 p.m.  E.S.T.  on that Valuation Date. If such request is received
          after 4:00 p.m.  E.S.T.,  such  request  shall be  effective as of the
          close of business on the next succeeding Valuation Date.

     (d)  The  Account  Value to be applied  pursuant to this  Section  shall be
          determined  as of the  applicable  Valuation  Date  determined  in (c)
          above.  If the  entire  Account  Value  of a  Participant  Account  is
          withdrawn,  the Participant shall be paid the Withdrawal Value. If the
          Participant  requests that a specified  percentage or dollar amount be
          paid to the  Participant,  AUL  shall  withdraw  from the  Participant
          Account an amount equal to the dollar amount to be paid divided by the
          difference  between 1 and the  decimal  equivalent  of the  applicable
          Withdrawal  Charge.  Notwithstanding  the  previous  sentence,  in any
          Contract  Year the  Participant  may withdraw up to 10% of the Account
          Value of his  Participant  Account  determined as of the last Contract
          Anniversary   preceding  the  request  for  the   withdrawal   without
          application  of any  Withdrawal  Charge,  provided that 12 months have
          elapsed from the date that the  Participant's  first  Contribution  is
          credited  to his  Participant  Account  by AUL to  the  date  of  such
          withdrawal. Also, where a Participant has outstanding loans under this
          contract,  a  partial  withdrawal  by a  Participant  from  the  Fixed
          Interest  Account  shall  be  permitted  only to the  extent  that the
          remaining  Withdrawal  Value  of the  Participant  held  in the  Fixed
          Interest   Account  equals  twice  the  total  of  the   Participant's
          outstanding loans under this contract.
<PAGE>

     (e)  AUL shall pay such amount in a cash lump sum to the Participant.  Such
          cash  lump sum  will be paid  within  7 days  from  the date  that AUL
          receives the withdrawal request at its Home Office,  except as AUL may
          be  permitted  to defer such  payment of  amounts  withdrawn  from the
          Variable  Account in  accordance  with  appropriate  provisions of the
          federal  securities  laws. AUL reserves the right to defer the payment
          of amounts with drawn from the Fixed Interest  Account for a period of
          up to 6 months after AUL receives the  withdrawal  request at its Home
          Office.

     (f)  Withdrawals  from a Participant  Account's share of the Fixed Interest
          Account shall be made on a  first-in/first-out  basis so that all or a
          portion of the amounts credited to the Participant  Account's share of
          the Fixed  Interest  Account  (other than amounts which are prohibited
          from being  distributed  because  provision  (a)(1)  above is not met)
          which have been on deposit for the longest  period of time, as well as
          the interest credited thereon, shall be withdrawn first.

4.9  Loans from the Fixed Interest Account:

     (a)  A  Participant  who has all or a portion of his Account  Value held in
          the Fixed  Interest  Account  may borrow  money  from AUL,  using such
          Account Value held in the Fixed Interest  Account as the only security
          for the loan,  by  submitting a proper  written  request to AUL at its
          Home  Office.  The minimum  amount of any single  loan is $2,000.  The
          maximum  amount that may be  borrowed at any time is an amount  which,
          when  combined  with the  largest  loan  balance  during  the prior 12
          months,  does not exceed the lesser of (l) 50% of the Withdrawal Value
          of the Participant  Account held in the Fixed Interest Account, or (2)
          $50,000.  The Withdrawal Value of the Participant  Account held in the
          Fixed Interest Account, which must be at least twice the amount of the
          outstanding  loan balance,  shall serve as security for the loan,  and
          shall continue to earn interest. Payment by AUL of the loan amount may
          be delayed for up to 6 months.

     (b)  Interest  will be charged  for the loan,  and will  accrue on the loan
          balance from the effective  date of such loan. The interest rate shall
          be declared by AUL at the  beginning  of each  calendar  quarter.  The
          interest  rate charged  shall be equal to the Moody's  Corporate  Bond
          Yield Average - Monthly Average Corporates as of the date of the loan,
          as published by Moody's  Investors  Service.  If  publication  of such
          Moody's rate should ever cease, a substantially  equivalent substitute
          rate shall be used. However,  no change from a previously  established
          rate  may be  made  in an  amount  less  than  .50%  in  any  periodic
          adjustment.  The loan balance  shall also be subject to a loan expense
          charge equal to 2% of each loan repayment.

     (c)  Loans to Participants  must be repaid to AUL within a term of 5 years,
          unless  the  Participant  certifies to AUL that the loan is to be used
          to acquire a principal  residence for the  Participant,  in which case
          the  term  may be  longer.  Loan  repayments  must be  made  at  least
          quarterly.  Upon  receipt  of a  repayment,  AUL shall  deduct  the 2%
          expense charge from the repayment, and shall apply the balance of such
          repayment  first to any accrued  interest and then to the  outstanding
          loan principal.
<PAGE>

     (d)  If a loan either  remains unpaid at the end of its term, or if, at any
          time, l02% of the total of all the Participant's  loan balances equals
          the  Participant's  Withdrawal  Value  allocated to the Fixed Interest
          Account,  then AUL shall deduct these  balances plus an expense charge
          equal to 2% of the  outstanding  loan  balances  from the  Participant
          Account's  share of the Fixed Interest  Account.  If a Participant has
          outstanding  loans,  then  withdrawals  or  transfers  to the Variable
          Account shall be permitted  only to the extent that the  Participant's
          remaining  Withdrawal Value in the Fixed Interest Account equals twice
          the  total of any  outstanding  loans  of the  Participant  under  the
          contract.  All loan balances plus the 2% expense  charge shall be paid
          or satisfied in full before any amount from the Participant  Account's
          share of the Fixed Interest Account is paid as a full withdrawal, as a
          death   benefit,   upon   annuitization,   or  as  another   permitted
          distribution.

     (e)  AUL may modify the loan  restrictions  or limitations  stated above in
          this Section,  or may add new  restrictions  and  limitations,  to the
          extent necessary to comply with Code Section 72(p) or other applicable
          law, as determined solely by AUL.

                             ARTICLE 5 - VALUATIONS


5.1  Time of Valuation: All assets of each Portfolio shall be valued as provided
     in the prospectus for the Mutual Fund as such  prospectus may be amended or
     supplemented from time to time.

5.2  Accumulation  Units:  Any  amounts  that are  allocated  to any  Investment
     Account on behalf of a  Participant  shall be credited  to his  Participant
     Account in the form of Accumulation Units on the basis of the value of such
     units in that Investment  Account as of the end of the Valuation  Period on
     which such amounts are received by AUL at its Home Office.  Such  crediting
     shall be made separately for amounts allocated to each Investment  Account.
     The number of  Accumulation  Units in each Investment  Account  credited to
     each Participant  Account as of any Valuation Period shall be determined by
     dividing  the  amounts  allocated  to  that  Investment  Account  for  that
     Participant  Account as of such Valuation Period by the dollar value of one
     Accumulation Unit in that Investment Account as of the close of business on
     the applicable  Valuation  Period.  The number of  Accumulation  Units thus
     determined  shall not be  changed  by any  subsequent  change in the dollar
     value of the Accumulation Units.

5.3  Value of  Accumulation  Units:  The value of an  Accumulation  Unit in each
     Investment Account was established at $1.00 as of April 12, 1990. The value
     of an  Accumulation  Unit in each  Investment  Account as of any  Valuation
     Period  thereafter is equal to the dollar value of one Accumulation Unit in
     that Investment  Account as of the immediately  preceding  Valuation Period
     multiplied  by the Net  Investment  Factor,  as defined in Section 5.4, for
     that Investment  Account for the current Valuation Period.  The value of an
     Accumulation Unit for each Investment  Account shall be determined for each
     Valuation  Period before giving effect to any  additions,  withdrawals,  or
     transfers.  After  such  determination,  the  additions,   withdrawals,  or
     transfers which are effective as of that day shall then be made.

5.4  Determining the Net Investment  Factor:  The Net Investment Factor for each
     Investment  Account for any Valuation  Period is determined by dividing (a)
     by (b), and then subtracting (c) from that result, where:

     (a)  is equal to:

          (l)  the net asset value of a Portfolio  share held in the  Investment
               Account determined as of the end of the current Valuation Period,
               plus

          (2)  the per share  amount of any dividend or other  distribution,  if
               any, paid by the Portfolio during the current  Valuation  Period,
               plus or minus

          (3)  any credit or charge for any taxes  paid or  reserved  for by AUL
               during the current  Valuation  Period which are determined by AUL
               to be attributable to operation of the Investment Account;

     (b)  is the net asset  value of a  Portfolio  share held in the  Investment
          Account  determined  as  of  the  end  of  the  immediately  preceding
          Valuation Period; and

     (c)  is a daily  charge  factor  determined  by AUL to reflect  the charges
          assessed against the
<PAGE>

          assets of the Investment Account for mortality and expense risks.


5.5  Determining the Value of Each Participant Account's Share of any Investment
     Account:  The value of each  Participant  Account's share of any Investment
     Account as of any Valuation  Date shall be determined  by  multiplying  the
     Participant  Account's  aggregate  Accumulation  Units  in that  Investment
     Account as of such Valuation  Date by the dollar value of one  Accumulation
     Unit in that Investment Account as of such Valuation Date. The value of the
     Participant  Account's share of any Investment Account as of any date other
     than a Valuation Date is equal to the value of its share of that Investment
     Account as of the immediately preceding Valuation Date.

     tax,  securities,  or  other  statutes  or rules  shall  not be  deemed  to

8.15 Voting:

     (a)  AUL is the legal  owner of the shares of the  Mutual  Fund held by the
          Investment Accounts of the Variable Account. AUL shall exercise voting
          rights  attributable  to the  shares  of  each  Portfolio  held in the
          Investment  Accounts  at  any  regular  and  special  meetings  of the
          shareholders  of the  Mutual  Fund on  matters  requiring  shareholder
          voting under The  Investment  Company Act of l940 or other  applicable
          laws.  AUL shall  exercise  these voting rights based on  instructions
          received  from  persons  having the voting  interest in  corresponding
          Investment   Accounts  of  the  Variable  Account.   However,  if  The
          Investment Company Act of l940 or any regulations thereunder should be
          amended, or if the present  interpretation  thereof should change, and
          as a result AUL determines  that it is permitted to vote the shares of
          the Mutual Fund in its own right, it may elect to do so. AUL will vote
          shares of any Investment Account, if any, that it owns beneficially in
          its own  discretion,  except that if the Mutual Fund offers its shares
          to any insurance  company  separate  account that funds  variable life
          insurance  contracts or if otherwise  required by applicable  law, AUL
          will  vote  its  own  shares  in the  same  proportion  as the  voting
          instructions  that are received in a timely  manner for  contracts and
          Participant Accounts participating in the Investment Account.

     (b)  The persons  having the voting  interest  under this  contract are the
          Participants.  Unless otherwise required by applicable law, the number
          of Mutual Fund shares of a  particular  Portfolio  as to which  voting
          instructions  may be given to AUL is  determined by dividing the value
          of all of  the  Accumulation  Units  of the  corresponding  Investment
          Account  attributable to this contract on a particular date by the net
          asset  value  per  share  of  that  Portfolio  as of  the  same  date.
          Fractional  votes  will be  counted.  The  number of votes as to which
          voting  instructions  may be given will be  determined  as of the date
          coincident   with  the  date   established  by  the  Mutual  Fund  for
          determining shareholders eligible to vote at the meeting of the Mutual
          Fund.  If required by the  Securities  and  Exchange  Commission,  AUL
          reserves  the right to  determine  in a  different  fashion the voting
          rights attributable to the shares of the Mutual Fund.

<PAGE>


     (c)  Voting rights attributable to this contract for which no timely voting
          instructions  are received will be voted by AUL in the same proportion
          as the voting  instructions  which are received in a timely manner for
          all  contracts  and  Participant   Accounts   participating   in  that
          Investment Account.

     (d)  Neither the  Variable  Account nor AUL is under any duty to inquire as
          to the  instructions  received or the  authority  of  Contractholders,
          Participants, or others to instruct the voting of Mutual Fund shares.

     (e)  Every person or entity  having such voting  rights shall  receive such
          reports or prospectuses  concerning the Variable Account or the Mutual
          Fund as may be required by applicable federal law.

8.16 Acceptance of New Participants or Contributions.  AUL reserves the right to
     refuse to accept new Participants or new  Contributions to this contract at
     any time. AUL shall have the right to refuse to accept  Contributions as of
     the last day of the second month  following the date that written notice to
     this  effect  is  delivered  to  any  contributing  Participant  or to  any
     Participant for whom Contributions are being made.

8.17 Nonforfeitability and Nontransferability:  The entire Withdrawal Value of a
     Participant  Account under this  contract  shall be  nonforfeitable  at all
     times. No sum payable under this contract with respect to a Participant may
     be sold,  assigned,  discounted,  or pledged as collateral for a loan or as
     security for the  performance  of an obligation or for any other purpose to
     any person or entity other than AUL. In addition,  to the extent  permitted
     by law, no such sum shall in any way be subject to legal process  requiring
     the payment of any claim against the payee.

8.18 Termination:  This contract  shall  automatically  terminate as of the date
     that there are no Participant Accounts maintained hereunder.

8.19 Notice of Annual  Meeting of  Members:  The regular  annual  meeting of the
     members of AUL (i.e., contractholders) shall be held at its principal place
     of business  on the third  Thursday in February of each year at the hour of
     ten  o'clock  A.M.  Elections  for  directors  shall be held at such annual
     meeting.

                                     TO THE

                                    ISSUED BY
                  AMERICAN UNITED LIFE INSURANCE COMPANY (AUL)
                                       TO

            The Effective Date of this Amendment is JANUARY 1, 2000.

AUL and the Contractholder  hereby agree, by signing below, that the Contract is
amended as follows:

By deleting the term "death benefit"  wherever it appears in the Contract and by
substituting "Death Benefit" in lieu thereof.

And by deleting the corresponding Sections or Subsections of the Contract and by
substituting  the following  Sections or  Subsections  in lieu  thereof,  and by
making  any  required  corresponding  changes  in the Table of  Contents  of the
Contract:

1.10A "Death Benefit" is the greater of:

     (a)  the  Participant's  Account  Value as of the date the Death Benefit is
          calculated, or

     (b)  (1) the  Guaranteed  Minimum  Death  Benefit  (GMDB)  on the  Contract
          Anniversary immediately preceding the date of the Participant's death;
          increased by

          (2)  any  Contributions  made  for  the  Participant  since  the  last
               Contract Anniversary; and reduced proportionately to reflect

          (3)  any  withdrawals  for the  Participant  since  the last  Contract
               Anniversary.

1.12AThe  "Guaranteed  Minimum  Death  Benefit"  or  "GMDB"  prior to the  first
     Contract  Anniversary is equal to the Contributions  made for a Participant
     minus any of his withdrawals or loans. On each Contract  Anniversary  prior
     to, or concurrent with, the Participant's date of death, the GMDB is reset,
     based on the age of the Participant on his last birthday, as follows:

     (a)  For  Participants  less than 81 years of age,  the GMDB is the greater
          of:

          (1)  the  Participant's  Account  Value  as of  the  current  Contract
               Anniversary, or

          (2)  (i)  the   GMDB  as  of  the   immediately   preceding   Contract
               Anniversary; increased by

               (ii) any  Contributions   made  for  the  Participant  since  the
                    immediately  preceding  Contract  Anniversary;  and  reduced
                    proportionately to reflect

               (iii)any withdrawals  for the  Participant  since the immediately
                    preceding Contract Anniversary.


P-12833.NOLOADTDAGMDB.AMD.1
<PAGE>

     (b)  For Participants 81 years of age or older, the GMDB is equal to:

          (1)  the GMDB as of the immediately  preceding  Contract  Anniversary;
               increased by

          (2)  any Contributions  made for the Participant since the immediately
               preceding Contract  Anniversary;  and reduced  proportionately to
               reflect

          (3)  any  withdrawals  for  the  Participant   since  the  immediately
               preceding Contract Anniversary.

     As of the  Participant's  date of death,  the GMDB  ceases to  increase  or
     decrease in value.

1.13 "Guaranteed Rate of Interest" means interest at an annual effective rate of
     3.00%.

6.3  Administrative  Charge:  AUL deducts an administrative  charge per Contract
     Quarter  equal to the lesser of $7.50 or 0.5% of the  Account  Value on the
     last  day of  each  Contract  Quarter  from  each  Participant  Account  in
     existence on that day for as long as the Participant  Account is in effect.
     This  charge is to be prorated  among each  subaccount  of the  Participant
     Account which  corresponds to each  Investment  Option  utilized under this
     contract  by  that  Participant   Account.  If  the  entire  balance  of  a
     Participant   Account  is  withdrawn   pursuant  to  this   contract,   the
     administrative  charge attributable to the period of time which has elapsed
     since the first day of the  Contract  Quarter  in which the  withdrawal  of
     funds is made is not deducted from the amount withdrawn.

     There is no charge for a Participant for any Contract  Quarter in which the
     Participant's Account Value on the last day of that quarter is greater than
     $25,000.

at the Current Rates of Interest.

(a)  Contributions  allocated,  or amounts  transferred,  to the Fixed  Interest
     Account  shall be  credited  to the open  interest  pocket  and shall  earn
     interest  at the  Current  Rate of  Interest  in effect  for that  interest
     pocket. Such Contributions or transferred amounts, during the time that the
     Current Rate of Interest  exceeds the  Guaranteed  Rate of Interest,  shall
     earn  interest at such  credited  Current  Rate of Interest  for at least 1
     year. After such 1-year period,  AUL reserves the right to declare,  at any
     time,  a new  Current  Rate of  Interest to be applied to funds held within
     that interest pocket.  Any such new Current Rate of Interest must remain in
     effect for that interest pocket for at least 1 year.

(b)  If AUL changes the Current  Rate of Interest for new  Contributions  or new
     amounts  transferred  to the Fixed  Interest  Account,  the  previous  open
     interest pocket shall close, and any  Contributions or amounts  transferred
     on or after the  effective  date of such change  shall be credited to a new
     open  interest  pocket and shall earn  interest at the new Current  Rate of
     Interest in effect for such new open  interest  pocket.  Therefore,  at any
     given time,  various funds credited to a Participant  Account and allocated
     to the Fixed Interest Account may be earning interest at different  Current
     Rates of Interest for different periods of time.

        Account Years                          Percentage

     shall not be the responsibility of AUL to determine the existence or amount
     of Excess  Contributions  or gains or losses  thereon,  or that  returns of
     Excess Contributions are permitted by applicable provisions of the Code and
     Regulations.  In withdrawing and returning the identified  amount,  AUL may

p-12834.3

     no later than the close of business on the second business day of AUL after
     the  later  of  (1)  the   business  day  that  AUL  receives  the  initial
     Contribution at its Home Office, or (2) the business day that AUL receives,
     at its Home Office, the data required to establish the Participant  Account
     and allocation instructions regarding the initial Contribution. If the data
     required to establish the Participant  Account and allocation  instructions
     regarding  the  initial  Contribution  are not  received by AUL at its Home
     Office  within 5  business  days  after  AUL  first  receives  the  initial
     Contribution, AUL shall return the initial Contribution to the contributing
     party  unless  consent is given to AUL to retain the  initial  Contribution
     until  AUL  receives  the  data  and   allocation   instructions   for  the
     Participant.   Alternatively,   if  the  data  required  to  establish  the
     Participant  Account  and  allocation  instructions  regarding  the initial
     Contribution  are not  received  by AUL at its Home  Office  when AUL first
     receives the initial  Contribution,  to the extent  permitted by applicable
     law,  AUL  may  allocate  the  initial  Contribution  to the  Money  Market
     Investment  Account,  and shall transfer such amounts credited to the Money
     Market   Investment   Account   according  to  the  applicable   allocation
     instructions upon receipt of the data required to establish the Participant
     Account and allocation instructions.

     and allocated as of the close of business on the Valuation  Period in which
     AUL  receives  the  Contribution  at its  Home  Office,  provided  that the
     Contribution  is  received  by 4:00  p.m.  E.S.T.  If the  Contribution  is
     received after 4:00 p.m. E.S.T.,  such  Contribution  shall be deemed to be
     received,  and shall be credited and allocated as of the close of business,
     on the next succeeding Valuation Period.

(f)  Within  any one  Participant  Account,  the  amount  so  credited  shall be
     allocated to an Investment Option in increments of 10%, 25%, or 33-1/3%, as
     elected by the Participant in writing. If no allocation instruction is made
     with respect to any Participant  Account, AUL shall process such credits in
     accordance  with the allocation  instruction  applicable to the immediately
     preceding  Contribution.  If  there  should  be no  allocation  instruction
     applicable  to  a  portion  of  a  Contribution   other  than  the  initial
     Contribution,  that amount shall be credited to the Fixed Interest  Account
     until such time as an appropriate  allocation  instruction is received,  at
     which time such amount shall be withdrawn from the Fixed  Interest  Account
     and allocated pursuant to such instructions.  The Participant may change an
     allocation   instruction   with  respect  to  future   allocations  to  his
     Participant Account by giving new written allocation instructions to AUL at
     its Home Office.

     additions to,  deletions from,  substitution  for, or combinations  of, the
     securities that are held by the Variable Account or any Investment  Account
     or that the Variable  Account or any Investment  Account may purchase.  AUL
     reserves  the  right  to  eliminate  the  shares  of any  of  the  eligible
     Portfolios and to substitute  shares of, or interests in, another Portfolio
     of the Mutual Fund, of another open-end,  registered investment company, or
     other investment  vehicle,  for shares already purchased or to be purchased
     in the future under the Contract.

(b)  AUL reserves the right to establish additional Investment Accounts, each of
     which  would  invest in a new  Portfolio  of the Mutual  Fund,  or in other
     securities,  investment vehicles, or shares of another diversified open-end
     management  investment company or series thereof. AUL reserves the right to
     eliminate  or  combine  existing   Investment  Accounts  if,  in  its  sole
     discretion,  marketing,  tax, or investment conditions so warrant. AUL also
     reserves the right to provide other  Investment  Options under the Contract
     at any time. Subject to any required regulatory approvals, AUL reserves the
     right to transfer  assets from any Investment  Account to another  separate

     voting rights under the Contract, the Variable Account may be operated as a
     management  investment  company under The Investment Company Act of 1940 or
     any other form permitted by law, it may be  deregistered  in the event such

     shall be valued as of the close of business on the Valuation  Date that AUL
     receives the  Participant's  direction,  provided  that AUL  receives  such

     amounts from the Fixed Interest  Account for a period of 6 months after AUL
     receives the transfer request at its Home Office.

     Participant  Account's share of the Fixed Interest Account determined as of
     the last contract  anniversary  preceding the request for transfer,  or the
     Participant  Account's  entire share of the Fixed Interest  Account if such
     share would be less than $500 after the transfer.

(f)  AUL reserves the right to change the limitation on the minimum transfer, to
     change the limit on remaining  balances,  to limit the number and frequency
     of transfers, to suspend the transfer privilege,  and to impose a charge on
     a transfer.

(g)  Where a Participant  has outstanding  loans under the Contract,  a transfer
     from the Fixed Interest  Account to the Variable Account shall be permitted
     only to the extent that the remaining Withdrawal  Value of the  Participant
     held  in  the  Fixed  Interest  Account  equals  twice  the  total  of  the

At the written request of the  Participant,  AUL shall apply all or a portion of
the Account Value (subject to any appropriate  premium tax charge, and minus any
outstanding  loan balance of the  Participant  and any unpaid expense charges on
such loans) of the  Participant  Account  for the  purpose of  providing a fixed
payment annuity.  Upon receipt of such request, AUL is hereby authorized by such
Participant  to  value  and  transfer  the  Participant  Account's  share of the
Variable  Account to the Fixed Interest Account as of the date that AUL receives
such written request at its Home Office.  Such transferred amounts shall be held
in the Fixed Interest Account until the Participant's Annuity Commencement Date.
The Participant  request shall include  certification  as to the purpose for the
annuity and the election of one of the following annuity options:

(a)  Life Annuity.  The monthly annuity shall be payable to the annuitant for as
     long as the annuitant  lives,  and shall end with the last monthly  payment
     before the death of the annuitant.

(b)  Certain  and Life  Annuity.  The  monthly  annuity  shall be payable to the
     annuitant for as long as the annuitant  lives. If the annuitant dies before
     receiving  payments  for the  certain  period (5,  10, 15, or 20 years,  as
     specified in the election),  any remaining  payments for the balance of the
     certain period shall be paid to the annuitant's beneficiary.

(c)  Survivorship Annuity. The monthly annuity shall be payable to the annuitant
     for as long as the annuitant  lives.  After the death of the  annuitant,  a
     portion (all, 2/3, or 1/2, as specified in the election) of the annuitant's
     monthly  annuity  shall be paid to the  contingent  annuitant  named in the
     election for as long as the contingent annuitant lives. An election of this

     annuitant for as long as the annuitant  lives,  and shall end with the last
     monthly payment before the death of the annuitant.  If, at the death of the
     annuitant, the sum of the monthly payments previously received is less than
     the amount  applied to provide the  annuity,  monthly  payments of the same
     amount shall continue to the annuitant's beneficiary until the total of the
     monthly payments received equals such amount.

(e)  Fixed Period.  The monthly  annuity shall be payable to the annuitant for a
     fixed  period of time  (not  less  than 5 years nor more than 30 years,  as

     have been made for less than the selected  fixed  period,  monthly  annuity
     payments  to the  annuitant's  beneficiary  shall be  continued  during the

Home Office at least 30 days prior to the Annuity Commencement Date, the Account
Value (subject to any appropriate  premium tax charge, and minus any outstanding
loan balance of the Participant and any unpaid expense charges on such loans) of
his  Participant  Account  shall be applied under (b) above as a 10 Year Certain

Commencement   Date,  written   designation  of  the  contingent   annuitant  or
beneficiary, and any election forms needed in connection with any annuity option
provided.

In no event shall any option elected provide annuity benefits to the Participant

certain period beyond the life expectancy of such  Participant or the joint life
expectancy of such  Participant and such  contingent  annuitant as determined on
the Annuity Commencement Date.

If the  total  Account  Value  is  less  than  $2,000,  such  value  (minus  any
outstanding  loan balances of the  Participant  and any unpaid expense charge on
such loans) shall be paid in a lump sum to the annuitant  rather than annuitized

     specified in the election),  any remaining  payments for the balance of the
     certain period shall be paid to the annuitant's beneficiary.

(c)  Survivorship Annuity. The monthly annuity shall be payable to the annuitant
     for as long as the annuitant  lives.  After the death of the  annuitant,  a

     monthly  annuity  shall be paid to the  contingent  annuitant  named in the
     election for as long as the contingent annuitant lives. An election of this
     option  is  automatically  cancelled  if  either  the  Participant  or  the
     contingent annuitant dies before the Annuity Commencement Date.

(d)  Unit  Refund Life  Annuity.  The  monthly  annuity  shall be payable to the
     annuitant for as long as the annuitant  lives,  and shall end with the last

     fixed  period of time  (not  less  than 5 years nor more than 30 years,  as
     specified in the  election).  If, at the death of the  annuitant,  payments
     have been made for less than the selected  fixed  period,  monthly  annuity
     payments  to the  annuitant's  beneficiary  shall be  continued  during the
     remainder of such fixed period.

     due proof of the  Participant's  (and, if  applicable,  the  beneficiary's)
     death during the  Accumulation  Period at its Home Office,  AUL shall apply
     the Account Value (minus the  Participant's  outstanding  loan balance,  if
     any, under the Contract and any unpaid  expense  charges due on such loans)
     of the  Participant  Account for the purpose of providing a death  benefit.
     The death benefit shall be paid to the beneficiary last properly designated
     in writing to AUL at its Home Office by the Participant, or, if there is no
     designated  beneficiary  living on the date of the Participant's  death, to
     the Participant's  estate. If any beneficiary dies while receiving payments
     and no  beneficiary is designated to receive any remaining  payments,  such
     remaining payments shall be made to the deceased beneficiary's estate.


(b)  The Account  Value to be applied  pursuant to (a) above shall be determined
     as of the close of business on the later of (1) the Valuation Date that AUL
     receives such written instructions at its Home Office, or (2) the Valuation
     Date that AUL receives such due proof of death at its Home Office, provided
     that such written  instructions or due proof of death received on the later
     of (1) or (2) above  are (is) received by 4:00 p.m.  E.S.T.  If the written
     instructions  or due  proof of death  received  on the  later of (1) or (2)
     above are (is) received  after 4:00 p.m. E.S.T., such  valuation  shall  be
     made as of the close of business on the next succeeding Valuation Date.

(c)  (1)  The  benefit  shall be payable in accordance with one of the following
          provisions  as  elected  by  the Participant or the beneficiary if the
          Participant did not make an election:

          (i)  The  entire  Account  Value  to be  applied  shall be paid to the
               beneficiary  in a single sum or by another  elected  method on or
               before  December 31 of the calendar year which contains the fifth
               anniversary of the date of the Participant's death; or

          (ii) The benefit  shall be paid as an annuity in  accordance  with the
               Annuity  Options shown above over a period not to exceed the life
               or life expectancy of the beneficiary.  If the beneficiary is not
               the Participant's  surviving spouse, the annuity must begin on or
               before December 31 of the calendar year immediately following the
               calendar year in which the  Participant  died. If the beneficiary
               is the Participant's surviving spouse, the annuity need not begin
               before  December 31 of the calendar year in which the Participant
               would have attained age 70 1/2.

     (2)  If a Participant dies on or after his Annuity  Commencement  Date, any
          interest  remaining under the Annuity Option selected shall be paid at
          least as rapidly as prior to the Participant's death.

     (3)  If  payment  is to be made in a cash lump sum,  payment  shall be made
          within 7 days of the date of  valuation,  as  determined in (b) above,
          except  as AUL may be  permitted  to defer  such  payment  of  amounts
          derived from the Variable Account in accordance with the provisions of
          federal  securities  laws.  Also,  AUL reserves the right to defer the
          payment of amounts  withdrawn  from the Fixed  Interest  Account for a
          period of 6 months after AUL receives written instructions at its Home
          Office.

Withdrawal Benefits:

(a)  Except as stated below,  a  Participant,  upon  submitting a proper written
     request to AUL at its Home  Office,  may direct  AUL to  withdraw  all or a
     portion of the  Account  Value  (subject to the  Withdrawal  Charge) of his
     Participant Account, provided that:

     (l)  any   distribution  to  a  Participant   shall  not  occur  until  the
          Participant has:

          (i)  attained age 59 1/2; or

          (ii) terminated employment; or

          (iii) become totally  disabled  (as  defined by the  Internal  Revenue
               Service); or

          (iv) experienced  a  hardship  (as  defined  by the  Internal  Revenue
               Service); or

     (2)  the amount being withdrawn is attributable to Contributions made other
          than pursuant to a salary reduction  agreement  (within the meaning of
          Code Section 402(g)(3)(C)); or

     (3)  the amount  being  withdrawn  is  attributable  to amounts  held as of
          December 31, l988 under another Code Section 403(b) annuity contract.

     (4)  In the case of a hardship withdrawal referred to in (1)(iv) above, any
          gain credited to  Contributions  made  pursuant to a salary  reduction
          agreement may not be withdrawn.

     (5)  AUL  shall  not  be  responsible   for   determining  a  Participant's
          compliance with the requirements  above. Any withdrawal  request shall
          include  certification  as to  the  purpose  of  the  withdrawal.  The
          Participant  assumes full  responsibility for determining  whether the
          withdrawal is permitted under applicable law. AUL may rely solely upon
          the representations of the Participant made in the withdrawal request.

(b)  Withdrawals from a Participant  Account's share of an Investment Option may
     not be made in an amount less than the  smaller of $500 or the  Participant
     Account's entire share of the In vestment Option.  If a withdrawal  reduces
     the Participant  Account's share of an Investment Option to less than $500,
     such remaining share shall also be withdrawn (except for amounts prohibited
     from being distributed because provision (a)(1) above is not met).

(c)  A withdrawal  request shall be effective as of the close of business on the
     Valuation Date that AUL receives a proper written withdrawal request at its
     Home Office, provided that AUL receives such request by 4:00 p.m. E.S.T. on
     that Valuation  Date. If such request is received  after 4:00 p.m.  E.S.T.,
     such  request  shall be  effective  as of the close of business on the next
     succeeding Valuation Date.

(d)  The Account Value to be applied  shall be  determined as of the  applicable
     Valuation  Date  determined in (c) above.  If the entire Account Value of a
     Participant  Account  is  withdrawn,  the  Participant  shall  be paid  the
     Withdrawal Value. If the Participant  requests that a specified  percentage
     or dollar amount be paid to the  Participant,  AUL shall  withdraw from the
     Participant Account an amount equal to the dollar amount to be paid divided
     by the  difference  between 1 and

p-12834.8
<PAGE>

     the decimal equivalent of the applicable Withdrawal Charge. Notwithstanding
     the previous sentence, in any contract year the Participant may withdraw up
     to 10% of the Account Value of his Participant Account determined as of the
     last contract anniversary  preceding the request for the withdrawal without
     application of any Withdrawal Charge,  provided that 12 months have elapsed
     from the date that the Participant's  first Contribution is credited to his
     Participant  Account by AUL to the date of such  withdrawal.  Also, where a
     Participant has outstanding loans under the Contract,  a partial withdrawal
     by a Participant from the Fixed Interest Account shall be permitted only to
     the extent that the remaining  Withdrawal  Value of the Participant held in
     the Fixed  Interest  Account  equals  twice the total of the  Participant's
     outstanding loans under the Contract.

(e)  AUL shall pay such amount in a cash lump sum to the Participant.  Such cash
     lump sum will be paid  within 7 days  from the date that AUL  receives  the
     withdrawal  request at its Home  Office,  except as AUL may be permitted to
     defer such  payment  of  amounts  withdrawn  from the  Variable  Account in
     accordance with appropriate  provisions of the federal securities laws. AUL
     reserves the right to defer the payment of amounts withdrawn from the Fixed
     Interest  Account  for a period of up to 6 months  after AUL  receives  the
     withdrawal request at its Home Office.

(f)  Withdrawals  from a  Participant  Account's  share  of the  Fixed  Interest
     Account  shall  be  made on a  first-in/first-out  basis  so that  all or a
     portion of the amounts  credited to the Participant Account's  share of the
     Fixed Interest  Account (other than amounts which are prohibited from being
     distributed  because  provision (a)(1) above is not met) which have been on
     deposit for the longest  period of time,  as well as the interest  credited
     thereon, shall be withdrawn first.


Loans from the Fixed Interest Account:

(a)  A  Participant  who has all or a portion of his  Account  Value held in the
     Fixed Interest  Account may borrow money from AUL, using such Account Value
     held in the Fixed  Interest  Account as the only  security for the loan, by
     submitting a proper written request to AUL at its Home Office.  The minimum
     amount  of any  single  loan is  $2,000.  The  maximum  amount  that may be
     borrowed at any time is an amount  which,  when  combined  with the largest
     loan balance during the prior 12 months,  does not exceed the lesser of (l)
     50% of the Withdrawal  Value of the  Participant  Account held in the Fixed
     Interest Account,  or (2) $50,000.  The Withdrawal Value of the Participant
     Account held in the Fixed  Interest  Account,  which must be at least twice
     the amount of the outstanding loan balance, shall serve as security for the
     loan,  and shall  continue  to earn  interest.  Payment  by AUL of the loan
     amount may be delayed for up to 6 months.

(b)  Interest will be charged for the loan,  and will accrue on the loan balance
     from the effective  date of such loan.  The interest rate shall be declared
     by AUL at the  beginning of each calendar  quarter.  The loan balance shall
     also  be  subject  to a  loan  expense  charge  equal  to 2% of  each  loan
     repayment.

(c)  Loans  to  Participants  must be  repaid  to AUL  within a term of 5 years,
     unless  the  Participant  certifies  to AUL  that the loan is to be used to
     acquire a principal  residence for the Participant,  in which case the term
     may be  longer.  Loan  repayments  must be made at  least  quarterly.  Upon
     receipt of a  repayment,  AUL shall  deduct the 2% expense  charge from the
     repayment,  and shall  apply the  balance  of such  repayment  first to any
     accrued interest and then to the outstanding loan principal.

<PAGE>





     elapsed from the date that the Participant's first Contribution is credited
     to his Participant Account by AUL to the date of such withdrawal.  Also,
     where a Participant has outstanding loans under the  Contract,   a  partial
     withdrawal  by a  Participant  from the  Fixed  Interest  Account  shall be
     permitted  only to the extent that the  remaining  Withdrawal  Value of the
     Participant  held in the Fixed  Interest  Account equals twice the total of
     the Participant's outstanding loans under the Contract.

(e)  AUL shall pay such amount in a cash lump sum to the Participant.  Such cash
     lump sum will be paid  within 7 days  from the date that AUL  receives  the
     withdrawal  request at its Home  Office,  except as AUL may be permitted to
     defer such  payment  of  amounts  withdrawn  from the  Variable  Account in
     accordance with appropriate  provisions of the federal securities laws. AUL
     reserves the right to defer the payment of amounts withdrawn from the Fixed
     Interest  Account  for a period of up to 6 months  after AUL  receives  the
     withdrawal request at its Home Office.

(f)  Withdrawals  from a  Participant  Account's  share  of the  Fixed  Interest
     Account  shall  be  made on a  first-in/first-out  basis  so that  all or a
     portion of the amounts  credited to the Participant Account's  share of the
     Fixed Interest  Account (other than amounts which are prohibited from being
     distributed  because  provision (a)(1) above is not met) which have been on
     deposit for the longest  period of time,  as well as the interest  credited
     thereon, shall be withdrawn first.

Loans from the Fixed Interest Account:

(a)  A  Participant  who has all or a portion of his  Account  Value held in the
     Fixed Interest  Account may borrow money from AUL, using such Account Value
     held in the Fixed  Interest  Account as the only  security for the loan, by
     submitting a proper written request to AUL at its Home Office.  The minimum
     amount  of any  single  loan is  $2,000.  The  maximum  amount  that may be
     borrowed at any time is an amount  which,  when  combined  with the largest
     loan balance during the prior 12 months,  does not exceed the lesser of (l)
     50% of the Withdrawal  Value of the  Participant  Account held in the Fixed
     Interest Account,  or (2) $50,000.  The Withdrawal Value of the Participant
     Account held in the Fixed  Interest  Account,  which must be at least twice
     the amount of the outstanding loan balance, shall serve as security for the
     loan,  and shall  continue  to earn  interest.  Payment  by AUL of the loan
     amount may be delayed for up to 6 months.

(b)  Interest will be charged for the loan,  and will accrue on the loan balance
     from the effective  date of such loan.  The interest rate shall be declared
     by AUL at the  beginning of each calendar  year.  The interest rate charged
     during a particular  calendar year shall be equal to the Moody's  Corporate
     Bond Yield  Average - Monthly  Average  Corporates  as published by Moody's
     Investors Service for October of the previous calendar year. If publication
     of  such  Moody's  rate  should  ever  cease,  a  substantially  equivalent
     substitute  rate  shall be  used.  However,  no  change  from a  previously
     established  rate may be made in an amount  less than .50% in any  periodic
     adjustment.  If the Moody's rate for any October decreases by at least .50%
     from the Moody's  rate for the  immediately  preceding  October,  AUL shall
     declare  such  reduced  interest  rate  to be in  effect  during  the  next
     succeeding  calendar year. The loan balance shall also be subject to a loan
     expense charge equal to 2% of each loan repayment.

p-12834.9-SC
<PAGE>


(c)  Loans  to  Participants  must be  repaid  to AUL  within a term of 5 years,
     unless  the  Participant  certifies  to AUL  that the loan is to be used to
     acquire a principal  residence for the Participant,  in which case the term
     may be  longer.  Loan  repayments  must be made at  least  quarterly.  Upon
     receipt of a  repayment,  AUL shall  deduct the 2% expense  charge from the
     repayment,  and shall  apply the  balance  of such  repayment  first to any
     accrued interest and then to the outstanding loan principal.

(d)  If a loan either remains unpaid at the end of its term, or if, at any time,
     l02% of the  total  of all  the  Participant's  loan  balances  equals  the
     Participant's  Withdrawal  Value  allocated to the Fixed Interest  Account,
     then AUL shall deduct these  balances plus an expense charge equal to 2% of
     the outstanding  loan balances from the Participant  Account's share of the
     Fixed  Interest  Account.  If a Participant  has  outstanding  loans,  then
     withdrawals or transfers to the Variable Account shall be permitted only to
     the extent that the Participant's  remaining  Withdrawal Value in the Fixed
     Interest  Account  equals twice the total of any  outstanding  loans of the
     Participant  under the  Contract.  All loan  balances  plus the 2%  expense
     charge  shall be paid or  satisfied  in full  before  any  amount  from the
     Participant Account's share of the Fixed Interest Account is paid as a full
     withdrawal, as a death benefit, upon annuitization, or as another permitted
     distribution.

(e)  AUL may modify the loan  restrictions  or limitations  stated above, or may
     add new  restrictions  and  limitations,  to the extent necessary to comply
     with Code Section 72(p) or other  applicable  law, as determined  solely by
     AUL.

                                   VALUATIONS

All assets of each  Portfolio  shall be valued as provided in the prospectus for
the Mutual Fund as such prospectus may be amended or  supplemented  from time to
time.

Any  amounts  that are  allocated  to any  Investment  Account  on  behalf  of a
Participant  shall  be  credited  to his  Participant  Account  in the  form  of
Accumulation  Units on the basis of the value of such  units in that  Investment
Account as of the end of the Valuation Period on which such amounts are received
by AUL at its Home Office.  Such crediting  shall be made separately for amounts
allocated to each Investment  Account.  The number of Accumulation Units in each
Investment  Account  credited to each  Participant  Account as of any  Valuation
Period shall be determined by dividing the amounts allocated to that In vestment
Account for that  Participant  Account as of such Valuation Period by the dollar
value of one  Accumulation  Unit in that  Investment  Account as of the close of
business on the applicable  Valuation Period.  The number of Accumulation  Units
thus  determined  shall not be  changed by any  subsequent  change in the dollar
value of the Accumulation Units.

The value of an Accumulation Unit in each Investment  Account was established at
$1.00 as of April 12, 1990. The value of an Accumulation Unit in each Investment
Account as of any  Valuation  Period  thereafter is equal to the dollar value of
one Accumulation Unit in that Investment Account as of the immediately preceding
Valuation Period multiplied by the Net Investment  Factor, as defined below, for
that  Investment  Account  for the  current  Valuation  Period.  The value of an
Accumulation  Unit for each  Investment  Account  shall be  determined  for each
Valuation  Period  before  giving  effect  to  any  additions,  withdrawals,  or
transfers. After such determination,  the additions,  withdrawals,  or transfers
which are effective as of that day shall then be made.

The Net Investment  Factor for each Investment  Account for any Valuation Period
is determined by dividing (a) by (b), and then subtracting (c) from that result,
where:

p-12834.10
<PAGE>

(a)  is equal to:

     (1)  the net  asset  value  of a  Portfolio  share  held in the  Investment
          Account determined as of the end of the current Valuation Period, plus

     (2)  the per share  amount of any dividend or other  distribution,  if any,
          paid by the Portfolio  during the current  Valuation  Period,  plus or
          minus


     (3)  any credit or charge for any taxes paid or reserved  for by AUL during
          the  current  Valuation  Period  which  are  determined  by  AUL to be
          attributable to operation of the Investment Account;

(b)  is the net asset value of a Portfolio share held in the Investment  Account
     determined as of the end of the immediately preceding Valuation Period; and

(c)  is a daily charge factor  determined by AUL to reflect the charges assessed
     against  the assets of the  Investment  Account for  mortality  and expense
     risks.

The value of each  Participant  Account's share of any Investment  Account as of
any Valuation Date shall be determined by multiplying the Participant  Account's
aggregate  Accumulation  Units in that  Investment  Account as of such Valuation
Date by the dollar value of one Accumulation Unit in that Investment  Account as
of such Valuation  Date.  The value of the  Participant  Account's  share of any
Investment  Account as of any date other than a  Valuation  Date is equal to the
value of its share of that Investment  Account as of the  immediately  preceding
Valuation Date.

                                  OTHER CHARGES

AUL shall deduct a daily  mortality  risk charge and a daily expense risk charge
equal to the daily equivalent of  an annual combined charge of 1.25% against the
average daily net assets of each Investment Account.

The Mutual Fund shall pay an investment advisory fee and certain other expenses,
which may include its operational and organizational  expenses,  as described in
the current  prospectus as it may be amended or supplemented  from time to time.
These expenses may vary from year to year. The net asset value of each Portfolio
reflects such investment advisory fee and other expenses which are deducted from
the assets of such Portfolio.

AUL shall deduct an administrative charge per Contract year quarter equal to the
lesser  of $7.50  or 0.5% of the  Account  Value  on the  last day of each  such
quarter  from each  Participant  Account in existence on such day for so long as
the Participant Account is in effect during the Accumulation Period. This charge
is to be  prorated  among  each  subaccount  of the  Participant  Account  which
corresponds  to each  Investment  Option  utilized  under the  Contract  by that
Participant Account.

AUL  reserves  the right to deduct a charge for each  transfer  transaction,  to
deduct the appropriate  premium tax charge, or to deduct the appropriate charges
for federal,  state, or local income taxes incurred by AUL that are attributable
to the Variable Account and its Investment Accounts.

Contractholder  or  Participants  the benefit of, any  provisions  of federal or

          attributable to operation of the Investment Account;

(b)  is the net asset value of a Portfolio share held in the Investment  Account
     determined as of the end of the immediately preceding Valuation Period; and

(c)  is a daily charge factor  determined by AUL to reflect the charges assessed
     against  the assets of the  Investment  Account for  mortality  and expense
     risks.

The value of each  Participant  Account's share of any Investment  Account as of
any Valuation Date shall be determined by multiplying the Participant  Account's
aggregate  Accumulation  Units in that  Investment  Account as of such Valuation
Date by the dollar value of one Accumulation Unit in that Investment  Account as
of such Valuation  Date.  The value of the  Participant  Account's  share of any
Investment  Account as of any date other than a  Valuation  Date is equal to the
value of its share of that Investment  Account as of the  immediately  preceding
Valuation Date.

                                  OTHER CHARGES

AUL shall deduct a daily  mortality  risk charge and a daily expense risk charge

quarter  from each  Participant  Account in existence on such day for so long as
the Participant Account is in effect during the Accumulation Period. This charge
is to be  prorated  among  each  subaccount  of the  Participant  Account  which
corresponds  to each  Investment  Option  utilized  under the  Contract  by that
Participant Account.

transaction,  to deduct the  appropriate  premium tax  charge,  or to deduct the
appropriate  charges for federal,  state,  or local income taxes incurred by AUL
that are attributable to the Variable Account and its Investment Accounts.

Annuity  Certificates:  AUL shall  issue to each  person  for whom an annuity is
purchased  from AUL a certificate  setting forth the amount and terms of payment
of the annuity.

Election, Notice, or Direction Requirements:  Wherever in the Contract reference
is made to the Contractholder or Participant  making a  request or giving notice
or direction,  such request, notice, or direction must be in writing and must be
submitted to, and received by, AUL at its Home Office before becoming effective,
unless the Participant is otherwise directed by AUL.

Quarterly  Statement of Account Value: As soon as reasonably  possible after the
end of each contract year quarter,  AUL shall prepare a statement of the Account
Value of each Participant Account existing under the Contract.

Sex and Number: Whenever the context of this Certificate so requires, the plural
includes the singular, the singular the plural, and the masculine the feminine.

Facility of Payment: If any Participant, contingent annuitant, or beneficiary is
legally  incapable  of giving a valid  receipt for any  payment due him,  and no
guardian has been appointed, AUL may make such

p-12834.12
<PAGE>


payment to the person or persons who have assumed the care and principal support
of such Participant,  contingent annuitant,  or beneficiary.  Also, AUL may make
payment  directly to any person or entity  when  directed to do so in writing by
the Participant.  Any payment made by AUL will fully discharge AUL to the extent
of such payment.

Insulation from Liability: The assets of the Variable Account are not chargeable
with liabilities arising out of any other business AUL may conduct.

Voting:

(a)  AUL is the  legal  owner  of the  shares  of the  Mutual  Fund  held by the
     Investment  Accounts of the Variable  Account.  AUL shall  exercise  voting
     rights  attributable to the shares of each Portfolio held in the Investment
     Accounts at any regular and  special  meetings of the  shareholders  of the
     Mutual Fund on matters  requiring  shareholder  voting under The Investment
     Company Act of l940 or other  applicable  laws.  AUL shall  exercise  these
     voting rights based on instructions received from persons having the voting
     interest in  corresponding  Investment  Accounts of the  Variable  Account.
     However,  if  The  Investment  Company  Act  of  l940  or  any  regulations
     thereunder  should be  amended,  or if the present  interpretation  thereof
     should change,  and as a result AUL determines that it is permitted to vote
     the shares of the Mutual Fund in its own right,  it may elect to do so. AUL
     will  vote  shares  of  any  Investment  Account,  if  any,  that  it  owns
     beneficially in its own  discretion,  except that if the Mutual Fund offers
     its shares to any insurance  company  separate  account that funds variable
     life insurance  contracts or if otherwise  required by applicable  law, AUL
     will vote its own shares in the same proportion as the voting  instructions
     that are received in a timely manner for contracts and Participant Accounts
     participating in the Investment Account.

(b)  The  persons  having  the  voting  interest  under  the  Contract  are  the
     Participants.

(c)  Voting  rights  attributable  to the  Contract  for which no timely  voting
     instructions  are received  will be voted by AUL in the same  proportion as
     the  voting  instructions  which are  received  in a timely  manner for all
     contracts  and  Participant  Accounts   participating  in  that  Investment
     Account.

(d)  Neither the Variable Account nor AUL is under any duty to inquire as to the
     instructions received or the authority of Contractholders, Participants, or
     others to instruct the voting of Mutual Fund shares.

(e)  Every person or entity having such voting rights shall receive such reports
     or prospectuses  concerning the Variable  Account or the Mutual Fund as may
     be required by applicable federal law.

Nonforfeitability  and  Nontransferability:  The  entire  Withdrawal  Value of a
Participant  Account under the Contract shall be nonforfeitable at all times. No
sum  payable  under the  Contract  with  respect to a  Participant  may be sold,
assigned, discounted, or pledged as collateral for a loan or as security for the
performance  of an  obligation  or for any other purpose to any person or entity
other than AUL. In addition,  to the extent  permitted by law, no such sum shall
in  any  way be subject  to legal  process  requiring  the  payment of any claim
against the payee.

Acceptance  of  Contributions:  AUL  shall  have the  right to  refuse to accept
Contributions  as of the last day of the second  month  following  the date that
written notice to this effect is delivered to any contributing Participant or to
any Participant for whom Contributions are being made.

                                    ADDENDUM
                                     TO THE
                                   CERTIFICATE
                        ISSUED TO THE PARTICIPANT IN THE
                                TDA MULTIPLE-FUND
                 GROUP VARIABLE ANNUITY CONTRACT (THE CONTRACT)
                                    ISSUED BY
                  AMERICAN UNITED LIFE INSURANCE COMPANY (AUL)


The Effective Date of this Addendum is the effective  date of the  corresponding
Amendment to the Contract.

Pursuant to this Addendum,  the corresponding  paragraph on the face page of the
Participant's  Certificate  under the  Contract  is  deleted  and the  following
paragraph is substituted in lieu thereof:

ACCUMULATION  UNITS IN ANY  INVESTMENT  ACCOUNT  FOR  WHICH THE  CONTRACT  MAKES
PROVISION MAY INCREASE OR DECREASE IN DOLLAR VALUE  ACCORDING TO THE  INVESTMENT
PERFORMANCE OF THE UNDERLYING ASSETS IN THE CORRESPONDING  MUTUAL FUND OR MUTUAL
FUND PORTFOLIO IN WHICH THE INVESTMENT ACCOUNT INVESTS. THE VALUE OF SUCH ASSETS
AND ACCUMULATION UNITS IS NOT GUARANTEED. ARTICLE 5 OF THE CONTRACT EXPLAINS THE
VALUATION OF SUCH ASSETS AND ACCUMULATION UNITS.

Pursuant to this Addendum,  the  corresponding  provisions of the  Participant's
Certificate under the Contract are hereby deleted,  and the following provisions
are substituted in lieu thereof:

                                   DEFINITIONS

"Contract  Anniversary" means the first day of the second Contract Year and each
subsequent  Contract Year.  Each Contract  Anniversary  after the First Contract
Anniversary  shall be the same day of the same month as the day and month  which
is stated on the face page of the Contract for the First Contract Anniversary.

"Contract  Year" means,  for the first such year, the period  beginning with the
Contract  Date  identified  in the  Contract  and ending on the day  immediately
preceding the First Contract Anniversary, and for each succeeding Contract Year,
the  period  beginning  with a  Contract  Anniversary  and  ending  on  the  day
immediately preceding the next succeeding Contract Anniversary.

"Contributions" means amounts paid to AUL from time to time by, or on behalf of,
Participants,  including  amounts  transferred  to the Contract from another AUL
group annuity contract,  which are credited to Participant  Accounts  maintained
hereunder.

"Investment  Account"  means each  subaccount  of the Variable  Account which is
maintained by AUL and made available to the Contractholder by AUL and identified
in Schedule A of the Contract.  Schedule A of the Contract may be amended by AUL
from time to time as  described  in  "Addition,  Deletion,  or  Substitution  of
Investments." Amounts allocated to any Investment Account identified in Schedule
A of the Contract  shall be invested in the shares of the  corresponding  Mutual
Fund or Mutual Fund Portfolio listed in the current  prospectus for the Variable
Account.

- -P-12834.X.ADD.1-
<PAGE>


"Mutual Fund" means the AUL American Series Fund, Inc., a diversified,  open-end
management  investment  company  registered under The Investment  Company Act of
l940, and any other such open-end
management investment company made available by AUL, as listed in Schedule A.

"Portfolio"  (also  known  as a  "Mutual  Fund  Portfolio")  means  a  portfolio
established  within a particular Mutual Fund as described in that prospectus for
that Mutual Fund, as such prospectus may be amended or supplemented from time to
time.

"Withdrawal  Charge"  means a charge taken by AUL equal to a  percentage  of the
Account Value withdrawn pursuant to "Withdrawal  Benefits," where the percentage
varies by the  Participant  Account Year in which the  withdrawal  is made.  The
first  Participant  Account  Year  begins  on the date  when AUL  establishes  a
Participant  Account and credits the initial  Contribution  for the Participant,
and ends on the day  immediately  preceding the next  anniversary  of such date.
Each Participant  Account Year thereafter begins on such an anniversary date and
ends on the day immediately preceding the next succeeding  anniversary date. The
Withdrawal Charge percentage is as follows:

             During                               Withdrawal Charge
     Participant Account Years                        Percentage

               1-5                                       8%
               6-10                                      4%
           Thereafter                                    0%

However,  for any Participant who also  participates in the companion AUL Series
III group annuity contract,  the initial  Withdrawal Charge percentage under the
Contract shall be equal to the Withdrawal  Charge  percentage  applicable to the
Participant  under the AUL Series I group annuity contract from which funds have
been  transferred  to such Series III contract,  determined  by AUL  immediately
prior to the date of such  transfer,  rounded down to the next whole  Withdrawal
Charge  percentage  if the  Withdrawal  Charge  percentage  under such  Series I
contract is a fractional  Withdrawal Charge percentage.  However, the Withdrawal
Charge  percentage  under this  paragraph  shall  never be greater  than 8%. The
Withdrawal  Charge  percentage  shall be  decreased  by 1% for  each  subsequent
Participant  Account  Year until the  Withdrawal  Charge  percentage  equals 4%.
(However,  if the applicable  Series I contract  Withdrawal Charge percentage is
less than 4%, it shall be rounded up to 4% in the Contract.)  This 4% Withdrawal
Charge  percentage shall be in effect during the next 6 consecutive  Participant
Account Years. Thereafter,  the Withdrawal Charge percentage shall be reduced to
0%.

In no event will the cumulative total of all Withdrawal Charges, including those
previously  assessed  against any amount  withdrawn from a Participant  Account,
exceed 9% of total Contributions allocated to that Participant Account.

                    CONTRIBUTIONS, INVESTMENTS, AND TRANSFERS

Contributions:

(a)  Contributions  may vary in amount and frequency;  however,  when made, they
     must be at  least  equal  to a  minimum  annual  Contribution  of $200  per
     Participant in any full Contract Year.

(c)  Within  any one  Participant  Account,  the  amount  so  credited  shall be
     allocated to an Investment Option in increments  elected by the Participant
     in a form acceptable to AUL. If no Investment

- -P-12834.X.ADD.2-
<PAGE>

     Option election is made with respect to a  particular  Contribution  to any
     Participant  Account, AUL shall process such credits in accordance with the
     Investment  Option  election   applicable  to  the  immediately   preceding
     Contribution. The Participant may change an Investment Option election with
     respect to future  allocations  to the  applicable  Participant  Account by
     giving new Investment  Option elections to AUL at its Home Office in a form
     acceptable to AUL.

(d)  The  initial  Contribution  for a  Participant  shall be  allocated  to the
     Participant  Account  no later  than the close of  business  on the  second
     business  day of AUL  after  the  later  of (1) the  business  day that AUL
     receives the initial  Contribution at its Home Office,  or (2) the business
     day that AUL receives,  at its Home Office,  the data required to establish
     the Participant Account,  instructions  regarding the amount of the initial
     Contribution for the Participant, and Investment Option elections regarding
     the initial Contribution.

(e)  If the data  required to establish a Participant  Account and  instructions
     regarding the amount of a Contribution for the Participant are not received
     by AUL at its Home Office within 5 business  days after AUL first  receives
     that  Contribution,  AUL shall return that Contribution to the contributing
     party  unless  the  contributing  party  consents  to  AUL  retaining  that
     Contribution  until the earlier of (i) the date AUL receives  such data and
     instructions and, therefore, can properly allocate that Contribution to the
     Participant  Account  or (ii) 25 days  from the date that  Contribution  is
     received by AUL.

(f)  If the data  required to establish a  Participant  Account,  including  any
     annuity  enrollment  form required by AUL, and  instructions  regarding the
     amount  of  a  Contribution  for  the  Participant  are  received,  but  an
     Investment Option election for that Participant is not received,  by AUL at
     its Home Office as of the date AUL first  receives that  Contribution,  AUL
     shall  allocate  that   Contribution  to  the  Investment  Option  election
     identified in the Participant's annuity enrollment form, which is generally
     the AUL  American  Money Market  Investment  Account.  If AUL  subsequently
     receives  the  data   required  to  establish  the   Participant   Account,
     instructions  regarding the amount of the Contribution for the Participant,
     and an  Investment  Option  election,  AUL shall then transfer such amounts
     credited  to the AUL  American  Money  Market  Investment  Account or other
     Investment Option identified in the Participant's  annuity enrollment form,
     plus gains or minus losses thereon,  to another  Investment Option, if such
     election so directs.

(g)  Contributions  for a  Participant  subsequent  to the initial  Contribution
     shall be allocated to the  Participant  Account as of the close of business
     on the  later of (1) the  Valuation  Period  in  which  AUL  receives  that
     Contribution  at its Home Office or (2) the  Valuation  Period in which AUL
     receives,   at  its  Home  Office,  the  data  required  to  establish  the
     Participant Account, instructions regarding the amount of that Contribution
     for the Participant, and Investment Option elections.

Addition, Deletion, or Substitution of Investments:

(a)  AUL reserves the right,  subject to compliance with applicable law, to make
     additions to,  deletions from,  substitution  for, or combinations  of, the
     securities that are held by the Variable Account or any Investment  Account
     or that the Variable  Account or any Investment  Account may purchase.  AUL
     reserves  the right to eliminate  the shares of any of the eligible  Mutual
     Funds or Mutual Fund  Portfolios and to substitute  shares of, or interests
     in,  another  Portfolio of the AUL  American  Series  Fund,  Inc.,  another
     open-end, registered investment company, or another investment vehicle, for
     shares  already  purchased  or to be  purchased  in the  future  under  the
     Contract,  if the shares of any or all eligible Mutual Funds or Mutual Fund
     Portfolios are no longer available for investment or if further  investment
     in any or all  eligible  Mutual  Funds or Mutual  Fund  Portfolios  becomes
     inappropriate  in view  of the  purposes  of the  Variable  Account  or the
     Contract.  Where required under applicable law, AUL will not substitute any
     shares in the Variable Account or any

- -P-12834.X.ADD.3-
<PAGE>

     Investment Account without notice, Participant approval,  or prior approval
     of the Securities and Exchange Commission or a state insurance commissioner
     and  without  following  the  filing  or other  procedures  established  by
     applicable  state  insurance  regulators.  Nothing  contained  herein shall
     prevent  the  Variable Account from purchasing other   securities for other
     series  or  classes  of  contracts, or  from effecting a conversion between
     series or classes of contracts  on the basis of requests made by a majority
     of participants or as permitted by federal law.

(b)  AUL reserves the right to establish additional Investment Accounts, each of
     which  would  invest  in the  corresponding  Mutual  Fund  or  Mutual  Fund
     Portfolio listed in the current prospectus for the Variable Account,  or in
     other  securities  or  investment  vehicles.  AUL  reserves  the  right  to
     eliminate or combine  existing  Investment  Accounts if marketing,  tax, or
     investment  conditions  so warrant.  AUL also reserves the right to provide
     other  Investment  Options  under the Contract at any time.  Subject to any
     required  regulatory  approvals,  AUL reserves the right to transfer assets
     from  any  Investment  Account  to  another  separate  account  of  AUL  or
     Investment Account.

(c)  In the event of any such  substitution  or change,  AUL may, by appropriate
     amendment,  make  such  changes  in the  Contract  as may be  necessary  or
     appropriate to reflect such  substitution or change. If deemed by AUL to be
     in the best interests of persons or entities having voting rights under the
     Contract,  the Variable Account may be operated as a management  investment
     company  under  The  Investment  Company  Act of  1940  or any  other  form
     permitted by law, it may be deregistered in the event such  registration is
     no longer  required under The Investment  Company Act of 1940, or it may be
     combined with other separate accounts of AUL or an affiliate  thereof.  AUL
     may take  such  action  as is  necessary  to  comply  with,  or to  obtain,
     exemptions  from the Securities and Exchange  Commission with regard to the
     Variable  Account.  Subject to compliance with applicable law, AUL also may
     combine one or more  Investment  Accounts  and may  establish a  committee,
     board, or other group to manage one or more aspects of the operation of the
     Variable Account.

Transfers:

(a)  Subject to the  limitations of (d) through (g) below,  the  Participant may
     direct AUL, in a form  acceptable to AUL, to transfer the amounts  credited
     to  an  Investment  Option  to  any  other  Investment  Option  during  the
     Accumulation  Period.  Any transfer  from an  Investment  Account  shall be
     effective  as of the  close of  business  on the  Valuation  Date  that AUL
     receives the Participant's transfer direction at its Home Office.

(d)  The minimum transfer from the Participant Account's share of any Investment
     Option is the lesser of $500 or the Participant  Account's  entire share of
     that  Investment  Option as of the close of business on the Valuation  Date
     that AUL receives that transfer direction at its Home Office.  However,  if
     that transfer  reduces the  Participant  Account's  remaining share of that
     Investment  Option to less than $500, the entire remaining share shall also
     be transferred.

(e)  Amounts  transferred  from  the  Fixed  Interest  Account  on  behalf  of a
     Participant   during  any  Contract  Year  shall  not  exceed  20%  of  the
     Participant  Account's share of the Fixed Interest Account determined as of
     the later of the  Contract  Date or the  Contract  Anniversary  immediately
     preceding the request for transfer.  Notwithstanding the previous sentence,
     if the Participant  Account's  share of the Fixed Interest  Account is less
     than $2,500 determined as of the later of the Contract Date or the Contract
     Anniversary  immediately  preceding  the request for  transfer,  the amount
     transferrable from the Fixed Interest Account for that Contract Year is the
     lesser  of $500 or the  Participant  Account's  entire  share of the  Fixed
     Interest Account as of the close of business on the Valuation Date that AUL
     receives that transfer  direction at its Home Office.  And if that transfer
     reduces the  Participant  Account's  remaining  share of the Fixed Interest
     Account  to less than  $500,  the  entire  remaining  share  shall  also be
     transferred.

                               BENEFITS AND LOANS

Annuity Options:

The last  paragraph of this section is deleted and the following  last paragraph
is substituted in lieu thereof:

If the  total  Account  Value  is  less  than  $2,000,  such  value  (minus  any
outstanding  loan balances of the  Participant and any unpaid expense charges on
such loans) shall be paid in a lump sum to the annuitant  rather than annuitized
under the annuity options  provided in (a) through (f) above.  Additionally,  if
the  proposed  monthly  annuity  payment  should fall below  AUL's  periodically
adjusted  minimum  monthly  annuity  payment,  AUL  reserves  the  right to make
payments on a less frequent basis (i.e., quarterly,  semiannually, or annually),
so that the actual annuity  payment is equal to or greater than the  established
minimum level, or to pay the Account Value (minus any outstanding  loan balances
of the  Participant  and any unpaid  expense  charges on such loans) in a single
sum.

Death Benefits:

(a)  Upon receipt of written  instructions  from the  Participant's  beneficiary
     (or, if applicable,  the secondary  beneficiary of the  Participant) and of
     due proof of the  Participant's  (and, if  applicable,  the  beneficiary's)
     death during the  Accumulation  Period at its Home Office,  AUL shall apply
     the Account Value (minus the  Participant's  outstanding  loan balance,  if
     any, under the Contract and any unpaid  expense  charges due on such loans)
     of the  Participant  Account for the purpose of providing a death  benefit.
     The death benefit shall be paid to the beneficiary last properly designated
     in writing to AUL at its Home Office by the Participant, or, if there is no
     designated  beneficiary  living on the date of the Participant's  death, to
     the Participant's estate. The Participant's  beneficiary may also designate
     a beneficiary.  If any  beneficiary  dies while  receiving  payments and no
     beneficiary is designated to receive any remaining payments, such remaining
     payments shall be made to the deceased beneficiary's estate.

(b)  The Account  Value to be applied  pursuant to (a) above shall be determined
     as of the close of  business  on the  Valuation  Date that AUL  receives  a
     proper withdrawal  request (or due proof of death, if received later), in a
     form acceptable to AUL, at its Home Office.

(c)  (1)  The benefit shall be  payable  in accordance with one of the following
          provisions as  elected  by  the  Participant or the beneficiary if the
          Participant did not make an election:

          (i)  The  entire  Account  Value  to be  applied  shall be paid to the
               beneficiary  in a single sum or other method not provided in (ii)
               below  on or  before  December  31 of  the  calendar  year  which
               contains the fifth  anniversary of the date of the  Participant's
               death; or

          (ii) The benefit  shall be paid as an annuity in  accordance  with the
               Annuity  Options shown in (a) through (f) above over a period not
               to exceed the life or life expectancy of the beneficiary.  If the
               beneficiary  is  not  the  Participant's  surviving  spouse,  the
               annuity must begin on or before  December 31 of the calendar year
               immediately  following the calendar year in which the Participant
               died. If the beneficiary is the  Participant's  surviving spouse,
               the annuity  need not begin  before  December 31 of the  calendar
               year in which the Participant would have attained age 70 1/2.

<PAGE>

     (2)  If a Participant dies on or after his Annuity  Commencement  Date, any
          interest  remaining under the Annuity Option selected shall be paid at
          least as rapidly as prior to the Participant's death.

     (3)  If  payment  is to be made in a cash lump sum,  payment  shall be made
          within 7 days of the date of  valuation,  as  determined in (b) above,
          except  as AUL may be  permitted  to defer  such  payment  of  amounts
          derived from the Variable Account in accordance with the provisions of
          federal  securities  laws.  Also,  AUL reserves the right to defer the
          payment of amounts  withdrawn  from the Fixed  Interest  Account for a
          period of up to 6 months after AUL receives proper instructions at its
          Home Office.

Withdrawal Benefits:

A Participant may direct AUL at its Home Office, in a form acceptable to AUL, to
withdraw all or a portion of the Withdrawal  Value of his  Participant  Account,
subject to the following provisions:

(a)  Amounts  attributable to amounts held as of December 31, 1988 under another
     Code Section 403(b) annuity contract may be withdrawn.

(b)  Amounts  attributable to Contributions made other than pursuant to a salary
     reduction  agreement (within the meaning of Code Section  402(g)(3)(C)) may
     be withdrawn.

(c)  Amounts  attributable to Contributions  made pursuant to a salary reduction
     agreement  (within  the  meaning  of  Code  Section  402(g)(3)(C))  may  be
     withdrawn,  provided that any  distribution of such amounts shall not occur
     until the  Participant  has  either  attained  age 59 1/2,  separated  from
     service,  become  totally  disabled  (as  defined by the  Internal  Revenue
     Service),  or  experienced  a hardship (as defined by the Internal  Revenue
     Service).  However, in the case of a hardship withdrawal, any gain credited
     to such Contributions may not be withdrawn.

(d)  Withdrawal of any amount from the Contract which is transferred directly by
     AUL pursuant to Participant  instructions to another  tax-deferred  annuity
     funding  vehicle  under  applicable  Internal  Revenue  Service  rules  and
     regulations shall be subject to application of the Withdrawal Charge.

(e)  If, as provided in Internal  Revenue Code  Regulation  Section  1.403(b)-2T
     Q&A-2, the distributee of any eligible rollover distribution elects to have
     the distribution  paid directly to an eligible retirement  plan (as defined
     in Q&A-1 of that  Section) and specifies  the eligible  retirement  plan to
     which the distribution is to be paid, then the  distribution  shall be paid
     to that eligible retirement plan in a direct rollover.

(f)  AUL shall not be responsible  for  determining a  Participant's  compliance
     with  the  requirements   above.  Any  withdrawal   request  shall  include
     certification as to the purpose of the withdrawal.  The Participant assumes
     full  responsibility  for  determining  whether the withdrawal is permitted
     under applicable law. AUL may rely solely upon the  representations  of the
     Participant made in the withdrawal request.

(g)  Withdrawals from a Participant Account's share of any Investment Option may
     not be made in an amount less than the  smaller of $500 or the  Participant
     Account's entire share of the Investment  Option.  If a withdrawal  reduces
     the Participant  Account's share of an Investment Option to less

- -p-12834.X.ADD.7
<PAGE>


     than  $500,  such  remaining  share  shall  also be  withdrawn  (except for
     amounts prohibited from  being  distributed  because paragraph (c) above is
     not met).

(h)  A  withdrawal  request  shall be  effective,  and the  Account  Value to be
     applied shall be  determined,  as of the close of business on the Valuation
     Date that AUL receives a proper withdrawal request, in a form acceptable to
     AUL, at its Home Office.  If it is necessary to withdraw the entire Account
     Value of a Participant Account to make a lump-sum cash payment,  the amount
     paid shall equal the Withdrawal  Value.  If it is not necessary to withdraw
     the entire Account Value to make such payment, AUL shall reduce the Account
     Value of the Participant  Account by an amount  sufficient to make the cash
     payment requested and to cover the Withdrawal Charge.  Notwithstanding  the
     previous  sentence,  in the  first  Contract  Year in  which a  Participant
     Account is established,  the Participant may withdraw from that Participant
     Account  up to 10% of the sum of the  Account  Value  of  that  Participant
     Account  (determined  as of the later of the Contract  Date or the Contract
     Anniversary  immediately  preceding  the request for the  withdrawal)  plus
     Contributions  made during that Contract Year,  without  application of the
     Withdrawal  Charge.  In the next succeeding  Contract Year, the Participant
     may also withdraw from that Participant Account up to 10% of the sum of the
     Account Value of that  Participant  Account  (determined as of the Contract
     Anniversary  immediately  preceding  the request for the  withdrawal)  plus
     Contributions  made during that Contract Year,  without  application of the
     Withdrawal  Charge.  In any subsequent  Contract Year, the  Participant may
     withdraw  from that  Participant  Account up to 10% of the Account Value of
     that  Participant  Account  (determined  as  of  the  Contract  Anniversary
     immediately  preceding the request for the withdrawal)  without application
     of the Withdrawal  Charge.  Also, where a Participant has outstanding loans
     under the Contract,  a partial  withdrawal by a Participant  from the Fixed
     Interest  Account shall be permitted  only to the extent that the remaining
     Withdrawal  Value of the  Participant  Account  held in the Fixed  Interest
     Account equals twice the total of the Participant's outstanding loans under
     the Contract.

(i)  AUL shall pay any cash lump sum to the  Participant  within 7 days from the
     appropriate Valuation Date as determined in Subsection (h) above, except as
     AUL may be permitted to defer such  payment of amounts  withdrawn  from the
     Variable Account in accordance with  appropriate  provisions of the federal
     securities  laws.  AUL  reserves  the right to defer the payment of amounts
     withdrawn  from the Fixed  Interest  Account for a period of up to 6 months
     after AUL receives the withdrawal request at its Home Office.

(j)  Withdrawals  from a  Participant  Account's  share  of the  Fixed  Interest
     Account  shall  be  made on a  first-in/first-out  basis  so that  all or a
     portion of the amounts  credited to the Participant  Account's share of the
     Fixed Interest  Account (other than amounts which are prohibited from being
     distributed  because  Subsection  (c) above is not met)  which have been on
     deposit for the longest  period of time,  as well as the interest  credited
     thereon, shall be withdrawn first.

                                   VALUATIONS

All  assets of each  Mutual  Fund or Mutual  Fund  Portfolio  shall be valued as
provided  in the  prospectus  for the  applicable  Mutual  Fund or  Mutual  Fund
Portfolio as such prospectus may be amended or supplemented from time to time.

Any amounts allocated to any Investment Account on behalf of a Participant shall
be credited to his Participant  Account in the form of Accumulation Units on the
basis of the value of such units in that  Investment  Account as of the later of
(1) the end of the Valuation Period on which such amounts are

<PAGE>

received  by AUL at its Home  Office or (2) the end of the  Valuation  Period on
which the data required to establish the  Participant  Account and allocate such
amounts to the Participant Account and to Investment Options are received by AUL
at its Home Office.  However,  if the initial  Contribution for a Participant is
allocated  pursuant to paragraph (d) of  "Contributions"  on the next succeeding
Valuation Period, the unit value as of the end of that Valuation Period shall be
used.  Such crediting  shall be made  separately  for amounts  allocated to each
Investment Account.  The number of Accumulation Units in each Investment Account
credited  to each  Participant  Account  as of any  Valuation  Period  shall  be
determined by dividing the amounts allocated to that Investment Account for that
Participant  Account  as of such  Valuation  Period by the  dollar  value of one
Accumulation Unit in that Investment  Account as of the close of business on the
applicable  Valuation Period.  The number of Accumulation  Units thus determined
shall  not be  changed  by any  subsequent  change  in the  dollar  value of the
Accumulation Units.

The  value of an  Accumulation  Unit in the AUL  American  Equity,  Bond,  Money
Market, and Managed Investment Accounts was established at $1.00 as of April 12,
1990.  The  value  of an  Accumulation  Unit  in any  other  Investment  Account
available under the Contract shall be established at $1.00 as of the date of the
first deposit to such Investment  Account.  The value of an Accumulation Unit in
each Investment  Account as of any Valuation  Period  thereafter is equal to the
dollar  value of one  Accumulation  Unit in that  Investment  Account  as of the
immediately  preceding Valuation Period multiplied by the Net Investment Factor,
as defined below, for that Investment  Account for the current Valuation Period.
The  value  of an  Accumulation  Unit  for  each  Investment  Account  shall  be
determined  for each  Valuation  Period before  giving effect to any  additions,
withdrawals, or transfers. After such determination, the additions, withdrawals,
or transfers which are effective as of that day shall then be made.

The Net Investment  Factor for each Investment  Account for any Valuation Period
is determined by dividing (a) by (b), and then subtracting (c) from that result,
where:

(a)  is equal to:

     (1)  the net asset value of a Mutual Fund or Mutual  Fund  Portfolio  share
          held in the Investment Account determined as of the end of the current
          Valuation Period, plus

     (2)  the per share  amount of any dividend or other  distribution,  if any,
          paid by the Mutual  Fund or Mutual Fund  Portfolio  during the current
          Valuation Period, plus or minus

     (3)  any credit or charge for any taxes paid or reserved  for by AUL during
          the  current  Valuation  Period  which  are  determined  by  AUL to be
          attributable to operation of the Investment Account;

(b)  is the net asset value of a Mutual Fund or Mutual Fund Portfolio share held
     in the  Investment  Account  determined  as of the  end of the  immediately
     preceding Valuation Period; and

(c)  is a daily charge factor  determined by AUL to reflect the charges assessed
     against  the assets of the  Investment  Account for  mortality  and expense
     risks, as authorized by the first paragraph of "Other Charges."

The value of each  Participant  Account's share of any Investment  Account as of
any Valuation Date shall be determined by multiplying the Participant  Account's
aggregate  Accumulation  Units in that  Investment  Account as of such Valuation
Date by the dollar value of one Accumulation Unit in that Investment  Account as
of such Valuation  Date.  The value of the  Participant  Account's  share of any
Investment  Account as of any date other than a  Valuation  Date is equal to the
value of its share of that Investment  Account as of the  immediately  preceding
Valuation Date.

                                  OTHER CHARGES

AUL shall deduct a daily  mortality  risk charge and a daily expense risk charge
equal to the daily  equivalent of an annual combined charge of 1.25% against the
average  daily net assets of each  Investment  Account.  These  charges shall be
reflected in the Net Investment Factor, as defined under "Valuations."

A Mutual Fund or Mutual Fund Portfolio shall pay any investment advisory fee and
certain  other  expenses,   which  may  include  its  ordinary  operational  and
organizational  expenses,  or any  extraordinary  expenses,  as described in the
current  prospectus  for that Mutual Fund or Mutual Fund  Portfolio as it may be
amended or supplemented  from time to time. These expenses may vary from year to
year.  The net asset value of each Mutual  Fund or Mutual Fund  Portfolio  share
reflects such investment advisory fee and other expenses which are deducted from
the assets of such Mutual Fund or Mutual Fund Portfolio.

AUL shall deduct an administrative charge per Contract Year quarter equal to the
lesser  of $7.50  or 0.5% of the  Account  Value  on the  last day of each  such
quarter  from each  Participant  Account in existence on such day for as long as
the Participant Account is in effect during the Accumulation Period. This charge
is to be  prorated  among  each  subaccount  of the  Participant  Account  which
corresponds  to each  Investment  Option  utilized  under the  Contract  by that
Participant Account.

AUL  reserves  the right to deduct a charge for each  transfer  transaction,  to
deduct the appropriate  premium tax charge, or to deduct the appropriate charges
for federal,  state, or local income taxes incurred by AUL that are attributable
to the Variable Account and its Investment Accounts.


                                  MISCELLANEOUS

Election, Notice, or Direction Requirements:  Wherever in the Contract reference
is made to the  Contractholder or Participant  making a request or giving notice
or direction,  such request,  notice,  or direction must be in writing,  or in a
form  otherwise  acceptable to AUL, and must be submitted to and received by AUL
at its Home Office  before  becoming  effective,  unless the  Contractholder  or
Participant is otherwise directed by AUL.

Voting:

(a)  AUL is the  legal  owner of the  shares  of a Mutual  Fund or  Mutual  Fund
     Portfolio  held by the  Investment  Accounts of the  Variable  Account.  In
     accordance  with its view of present law, AUL shall exercise  voting rights
     attributable  to the shares of each Mutual  Fund or Mutual  Fund  Portfolio
     held in the Investment  Accounts at any regular and special meetings of the
     shareholders of a Mutual Fund on matters requiring shareholder voting under
     The  Investment  Company Act of l940 or other  applicable  laws.  AUL shall
     exercise  these voting rights based on  instructions  received from persons
     having the voting  interest  in  corresponding  Investment  Accounts of the
     Variable  Account.  However,  if The Investment  Company Act of l940 or any
     regulations  thereunder should be amended, or if the present interpretation
     thereof should change,  and as a result AUL determines that it is permitted
     to vote the shares of a Mutual  Fund or Mutual  Fund  Portfolio  in its own
     right,  it may  elect to do so.  AUL will  vote  shares  of any  Investment
     Account,  if any, that it owns  beneficially in its own discretion,  except
     that if a Mutual  Fund or Mutual  Fund  Portfolio  offers its shares to any
     insurance  company  separate  account that funds  variable  life  insurance
     contracts or if otherwise required by applicable law, AUL will vote its own
     shares in the same proportion as the voting  instructions that are received
     in a timely manner for contracts and Participant Accounts  participating in
     the Investment Account.

                                  OTHER CHARGES

AUL shall deduct a daily  mortality  risk charge and a daily expense risk charge
equal to the daily  equivalent of an annual combined charge of 1.25% against the
average  daily net assets of each  Investment  Account.  These  charges shall be
reflected in the Net Investment Factor, as defined under "Valuations."

A Mutual Fund or Mutual Fund Portfolio shall pay any investment advisory fee and
certain  other  expenses,   which  may  include  its  ordinary  operational  and
organizational  expenses,  or any  extraordinary  expenses,  as described in the
current  prospectus  for that Mutual Fund or Mutual Fund  Portfolio as it may be
amended or supplemented  from time to time. These expenses may vary from year to
year.  The net asset value of each Mutual  Fund or Mutual Fund  Portfolio  share
reflects such investment advisory fee and other expenses which are deducted from
the assets of such Mutual Fund or Mutual Fund Portfolio.

AUL shall deduct an administrative charge per Contract Year quarter equal to the
lesser  of $3.00  or 0.5% of the  Account  Value  on the  last day of each  such
quarter  from each  Participant  Account in existence on such day for as long as
the Participant Account is in effect during the Accumulation Period. This charge
is to be  prorated  among  each  subaccount  of the  Participant  Account  which
corresponds  to each  Investment  Option  utilized  under the  Contract  by that
Participant Account.

AUL  reserves  the right to deduct a charge for each  transfer  transaction,  to
deduct the appropriate  premium tax charge, or to deduct the appropriate charges
for federal,  state, or local income taxes incurred by AUL that are attributable
to the Variable Account and its Investment Accounts.


                                  MISCELLANEOUS

Election, Notice, or Direction Requirements:  Wherever in the Contract reference
is made to the  Contractholder or Participant  making a request or giving notice
or direction,  such request,  notice,  or direction must be in writing,  or in a
form  otherwise  acceptable to AUL, and must be submitted to and received by AUL
at its Home Office  before  becoming  effective,  unless the  Contractholder  or
Participant is otherwise directed by AUL.

Voting:

(a)  AUL is the  legal  owner of the  shares  of a Mutual  Fund or  Mutual  Fund
     Portfolio  held by the  Investment  Accounts of the  Variable  Account.  In
     accordance  with its view of present law, AUL shall exercise  voting rights
     attributable  to the shares of each Mutual  Fund or Mutual  Fund  Portfolio
     held in the Investment  Accounts at any regular and special meetings of the
     shareholders of a Mutual Fund on matters requiring shareholder voting under
     The  Investment  Company Act of l940 or other  applicable  laws.  AUL shall
     exercise  these voting rights based on  instructions  received from persons
     having the voting  interest  in  corresponding  Investment  Accounts of the
     Variable  Account.  However,  if The Investment  Company Act of l940 or any
     regulations  thereunder should be amended, or if the present interpretation
     thereof should change,  and as a result AUL determines that it is permitted
     to vote the shares of a Mutual  Fund or Mutual  Fund  Portfolio  in its own
     right,  it may  elect to do so.  AUL will  vote  shares  of any  Investment
     Account,  if any, that it owns  beneficially in its own discretion,  except
     that if a Mutual  Fund or Mutual  Fund  Portfolio  offers its shares to any
     insurance  company  separate  account that funds  variable  life  insurance
     contracts or if otherwise required by applicable law, AUL will vote its own
     shares in the same proportion as the voting  instructions that are received
     in a timely manner for contracts and Participant Accounts  participating in
     the Investment Account.

(b)  The  persons  having  the  voting  interest  under  the  Contract  are  the
     Participants.

(c)  Voting  rights  attributable  to the  Contract  for which no timely  voting
     instructions  are received  will be voted by AUL in the same  proportion as
     the  voting  instructions  which are  received  in a timely  manner for all
     contracts  and  Participant  Accounts   participating  in  that  Investment
     Account.

(d)  Neither the Variable Account nor AUL is under any duty to inquire as to the
     instructions received or the authority of Contractholders, Participants, or
     others to  instruct  the  voting of Mutual  Fund or Mutual  Fund  Portfolio
     shares.

(e)  Every person or entity having such voting rights shall receive such reports
     or prospectuses  concerning the Variable Account or a Mutual Fund or Mutual

The Effective Date of this Addendum is the effective  date of the  corresponding
Amendment to the Contract.

Pursuant to this Addendum,  the Participant's  Certificate under the Contract is
hereby amended as follows:

By deleting the first  paragraph  of "Other  Charges"  and by  substituting  the
following first paragraph in lieu thereof:

                                  OTHER CHARGES

AUL shall deduct a daily  mortality  risk charge and a daily expense risk charge
equal to the daily  equivalent of an annual combined charge of 1.25% against the
average daily net assets of each  Investment  Account.  Additionally,  AUL shall
multiply the portions (as delineated in the table below) of the total  month-end
Account Value in the Variable Account of all Participants in the contract by the
monthly equivalent of the corresponding  Annual Variable Investment Plus Factors
appearing in the table below.  These products shall be added  together,  and the
sum  shall be  divided  by the total  month-end  Account  Value in the  Variable
Account of all Participants in the contract. This percentage shall be multiplied
by the month-end  Account Value of each Participant in each Investment  Account.
The  resulting  amount  for  each  Investment  Account  shall  be  added  to the
Participant's Account Value for that Investment Account.

                                    ADDENDUM
                                     TO THE
                                   CERTIFICATE
                        ISSUED TO THE PARTICIPANT IN THE
                               AUL AMERICAN SERIES
                    TDA MULTIPLE-FUND GROUP VARIABLE ANNUITY
                    CONTRACT NUMBER GA XX,XXX (THE CONTRACT)
                                    ISSUED BY
                  AMERICAN UNITED LIFE INSURANCE COMPANY (AUL)
                                       TO
                        ABC COMPANY (THE CONTRACTHOLDER)

                           EFFECTIVE DATE: MAY 1, 1993

Pursuant to this Addendum,  the  corresponding  provisions of the  Participant's
Certificate  under the Contract are hereby deleted and the following  provisions
are substituted in lieu thereof:

"Fixed Interest Account" means that fund of AUL's general asset account in which
all or a portion of a Participant's  Account Value may be held for  accumulation
at the Current Rates of Interest.

(a)  Contributions   allocated,  or  amounts  transferred  (excluding  transfers
     discussed in (c) below), to the Fixed Interest Account shall be credited to
     the open  interest  pocket and shall earn  interest at the Current  Rate of
     Interest  in  effect  for  that  interest  pocket.  Such  Contributions  or
     transferred  amounts,  during the time that the  Current  Rate of  Interest
     exceeds  the  Guaranteed  Rate of  Interest,  shall earn  interest  at such
     credited  Current Rate of Interest  for at least 1 year.  After such 1-year
     period, AUL reserves the right to declare,  at any time, a new Current Rate
     of Interest to be applied to funds held within that  interest  pocket.  Any
     such new Current Rate of Interest  must remain in effect for that  interest
     pocket for at least 1 year.

(b)  If AUL changes the Current Rate of Interest for such new  Contributions  or
     new amounts  transferred to the Fixed Interest  Account,  the previous open
     interest  pocket  shall  close,  and  any  such  Contributions  or  amounts
     transferred on or after the effective date of such change shall be credited
     to a new open  interest  pocket and shall earn  interest at the new Current
     Rate of Interest in effect for such new open interest pocket. Therefore, at
     any given  time,  various  funds  credited  to a  Participant  Account  and
     allocated  to the  Fixed  Interest  Account  may  be  earning  interest  at
     different Current Rates of Interest for different periods of time.

(c)  Any  contribution to another AUL P-12833 contract which is allocated to the
     Fixed  Interest  Account and which is  transferred  to this Contract  (plus
     gains and minus losses

P-12834.OT.ADD
<PAGE>

     thereon) and  allocated  to  the Fixed Interest Account, beginning with the
     date of such  transfer, shall be credited with the Current Rate of Interest
     under  this  Contract  which  was  in  effect  on  the date the transferred
     contribution was originally deposited into the Fixed Interest Account under
     the previous AUL contract.

"Investment  Account"  means  each  subaccount  of  the  Variable  Account  made
available  to the Contractholder  by  AUL  and  identified  in Schedule A of the
Contract.  Schedule A of the Contract may be amended by AUL from time to time as
described in "Addition,  Deletion,  or  Substitution  of  Investments."  Amounts
allocated to any  Investment  Account  identified  in Schedule A of the Contract
shall be  invested  in the shares of the  corresponding  Mutual  Fund  Portfolio
listed in the current prospectus for the Variable Account.


"Mutual Fund" means the AUL American Series Fund, Inc., a diversified,  open-end
management  investment  company  registered under The Investment  Company Act of
l940, and any other such open-end  management  investment company made available
by AUL.

"Portfolio"  means a series of a Mutual Fund as described in the  prospectus for
the Mutual Fund, as such prospectus may be amended or supplemented  from time to
time.

"Withdrawal  Charge"  means a charge taken by AUL equal to a  percentage  of the
Account Value of a Participant  Account withdrawn under the Contract,  where the
percentage  varies  by the  number  of full  years  measured  from the date that
Participant  Account is established,  or from the date a Participant  Account is
established  under a previous AUL P-12833  contract from which amounts have been
transferred to this Participant  Account,  to the date the Withdrawal  Charge is
determined. Such percentage is as follows:

          During
       Account Years                      Percentage

            1                                  6
            2                                  5
            3                                  4
            4                                  3
            5                                  2
            6                                  1
      Thereafter                               0

In no event will the cumulative total of all Withdrawal Charges, including those
previously assessed

P-12834.OT.ADD.1
<PAGE>

against any amount  withdrawn  from a  Participant  Account,  exceed 9% of total
Contributions allocated to that Participant Account.

Contributions:

(a)  Contributions  may  vary  in  amount  and  frequency;  however,  a  minimum
     Contribution  of at least  $100,000 must be made for a Participant in order
     to establish a  Participant  Account.  Any  additional  Contributions  made
     within the 12-month period  beginning on the date the initial  Contribution
     is credited to that Participant  Account  (hereinafter called a Certificate
     Year)  shall also be  credited  to that  Participant  Account.  Any initial
     Contribution made within a different Certificate Year shall also be subject
     to the $100,000 minimum, and any Contributions made within that Certificate
     Year shall be  allocated  to a separate  Participant  Account  and shall be
     evidenced  by a separate  Certificate  issued to the  Participant.  AUL may
     change the minimum Contribution acceptable under the Contract, but any such
     change shall apply only to individuals who become  Participants on or after
     the date of the change.

Addition, Deletion, or Substitution of Investments:

(a)  AUL reserves the right,  subject to compliance with applicable law, to make
     additions to,  deletions from,  substitution  for, or combinations  of, the
     securities that are held by the Variable Account or any Investment  Account
     or that the Variable  Account or any Investment  Account may purchase.  AUL
     reserves  the  right  to  eliminate  the  shares  of any  of  the  eligible
     Portfolios and to substitute  shares of, or interests in, another Portfolio
     of the AUL American  Series Fund,  Inc.,  of another  open-end,  registered
     investment  company,  or  other  investment  vehicle,  for  shares  already
     purchased  or to be  purchased  in the future  under the  Contract,  if the
     shares  of any or all  eligible  Portfolios  are no  longer  available  for
     investment,  or if, in AUL's  judgment,  further  investment  in any or all
     eligible  Portfolios  becomes  inappropriate in view of the purposes of the
     Variable Account or the Contract.  Where required under applicable law, AUL
     will not  substitute  any shares in the Variable  Account or any Investment
     Account  without  notice,  Participant  approval,  or prior approval of the
     Securities and Exchange Commission or a state insurance  commissioner,  and
     without following the filing or other procedures  established by applicable
     state  insurance  regulators.  Nothing  contained  herein shall prevent the
     Variable  Account  from  purchasing  other  securities  for other series or
     classes of  contracts,  or from  effecting a conversion  between  series or
     classes  of  contracts  on the  basis of  requests  made by a  majority  of
     participants or as permitted by federal law.

(b)  AUL reserves the right to establish additional Investment Accounts, each of
     which would invest in the corresponding Mutual Fund Portfolio listed in the
     current  prospectus  for the Variable  Account,  or in other  securities or
     investment  vehicles.  AUL  reserves  the  right to  eliminate  or  combine
     existing Investment Accounts if, in its sole discretion, marketing, tax, or
     investment

P-12834.OT.ADD.2
<PAGE>

     conditions  so  warrant.  AUL  also  reserves  the  right  to provide other
     Investment Options under this Contract at any time. Subject to any required
     regulatory approvals,  AUL reserves the right to transfer  assets from any
     Investment  Account  to  another  separate  account  of  AUL  or Investment
     Account.

(c)  In the event of any such  substitution  or change,  AUL may, by appropriate
     amendment,  make  such  changes  in the  Contract  as may be  necessary  or
     appropriate to reflect such  substitution or change. If deemed by AUL to be
     in the best interests of persons or entities having voting rights under the
     Contract,  the Variable Account may be operated as a management  investment
     company  under  The  Investment  Company  Act of  1940  or any  other  form
     permitted by law, it may be deregistered in the event such  registration is
     no longer  required under The Investment  Company Act of 1940, or it may be
     combined with other separate accounts of AUL or an affiliate  thereof.  AUL
     may take  such  action  as is  necessary  to  comply  with,  or to  obtain,
     exemptions  from the Securities and Exchange  Commission with regard to the
     Variable  Account.  Subject to compliance with applicable law, AUL also may
     combine one or more  Investment  Accounts  and may  establish a  committee,
     board, or other group to manage one or more aspects of the operation of the
     Variable Account.

Transfers:

(g)  Where a Participant  has outstanding  loans under the Contract,  a transfer
     from the Fixed Interest  Account to the Variable Account shall be permitted
     only to the extent that the remaining Withdrawal Value  of the  Participant
     Account held in the Fixed  Interest  Account  equals twice the total of the
     Participant's outstanding loans under that Participant Account.


Withdrawal Benefits:

(a)  (6)  Effective  January 1, 1993,  if, as provided in Internal  Revenue Code
     Regulation  Section  1.403(b)-2T  Q&A-2,  the  distributee  of any eligible
     rollover  distribution  elects to have the distribution paid directly to an
     eligible  retirement  plan  (as  defined  in  Q&A-1  of that  Section)  and
     specifies the eligible  retirement plan to which the  distribution is to be
     paid, then the distribution shall be paid to that eligible  retirement plan
     in a direct rollover.

(d)  The Account Value to be applied  shall be  determined as of the  applicable
     Valuation  Date  determined in (c) above.  If the entire Account Value of a
     Participant  Account  is  withdrawn,  the  Participant  shall  be paid  the
     Withdrawal Value. If the Participant  requests that a specified  percentage
     or dollar amount be paid to the  Participant,  AUL shall  withdraw from the
     Participant Account an amount equal to the dollar amount to be paid divided
     by the  difference  between 1 and the decimal  equivalent of the applicable
     Withdrawal  Charge.

<PAGE>



     Notwithstanding the previous sentence, in the first  Contract year in which
     a Participant Account is established, and in the next  succeeding  Contract
     year, the Participant may withdraw from that Participant  Account up to 10%
     of the sum of the Account Value of that Participant Account,  determined as
     of the last Contract anniversary  preceding the request for the withdrawal,
     plus  Contributions  made  during the  applicable  Contract  year,  without
     application of any Withdrawal  Charge In any subsequent  Contract year, the
     Participant  may withdraw  from that  Participant  Account up to 10% of the
     Account  Value  of that  Participant  Account,  determined  as of the  last
     Contract  anniversary  preceding  the request for the  withdrawal,  without
     application of any Withdrawal  Charge.  Where amounts have been transferred
     to the  Contract  from  another AUL  P-12833  contract,  Contract  years of
     participation  for  purposes  of  this  10%  free-out  provision  shall  be
     determined by using the date of the Participant's first contribution to the
     Participant  Account in the previous contract which was transferred.  Also,
     where a Participant  has  outstanding  loans under the Contract,  a partial
     withdrawal  by a  Participant  from the  Fixed  Interest  Account  shall be
     permitted  only to the extent that the  remaining  Withdrawal  Value of the
     Participant  Account held in the Fixed  Interest  Account  equals twice the
     total  of  the  Participant's  outstanding  loans  under  that  Participant
     Account.


Loans from the Fixed Interest Account:

(a)  A  Participant  who  has  all  or a  portion  of  the  Account  Value  of a
     Participant  Account  held in the Fixed  Interest  Account may borrow money
     from AUL,  using such Account Value held in the Fixed  Interest  Account as
     the only security for the loan, by submitting a proper  written  request to
     AUL at its Home  Office.  The minimum  amount of any single loan is $2,000.
     The maximum amount  that may be  borrowed  at any time is an amount  which,
     when  combined  with the largest loan  balance  during the prior 12 months,
     does  not  exceed  the  lesser  of (l) 50% of the  Withdrawal  Value of the
     Participant Account held in the Fixed Interest Account, or (2) $50,000. The
     Withdrawal  Value of the  Participant  Account  held in the Fixed  Interest
     Account,  which must be at least twice the amount of the  outstanding  loan
     balance,  shall serve as security for the loan,  and shall continue to earn
     interest.  Payment by AUL of the loan  amount  may be  delayed  for up to 6
     months.

(d)  If a loan either remains unpaid at the end of its term, or if, at any time,
     l02%  of  the  total  of  all  the  Participant's  loan  balances  under  a
     Participant Account equals the Withdrawal Value of that Participant Account
     allocated  to  the  Fixed  Interest  Account,  then  AUL shall deduct these
     balances  plus  an  expense  charge  equal  to 2% of the  outstanding  loan
     balances  from  the  Participant  Account's share  of  the  Fixed  Interest
     Account.  If a  Participant  has  outstanding  loans,  then  withdrawals or
     transfers  to  the  Variable  Account shall be permitted only to the extent
     that  the  Participant  Account's  remaining  Withdrawal Value in the Fixed
     Interest Account equals  twice  the total of any  outstanding  loans of the
     Participant  under that Participant  Account. All loan balances plus the 2%
     expense  charge  shall  be paid or satisfied in full before any amount from
     the Participant Account's share of the Fixed Interest  Account is paid as a
     full  withdrawal, as a death benefit, upon annuitization, or as another
     permitted distribution.


                                   VALUATIONS

All assets of each  Portfolio  shall be valued as provided in the prospectus for
the applicable  Mutual Fund as such  prospectus  may be amended or  supplemented
from time to time. Any amounts that are allocated to any  Investment  Account on
behalf of a Participant shall be credited to his Participant Account in the form
of Accumulation Units on the basis of the value of such units in that Investment
Account as of the end of the Valuation Period on which such amounts are received
by AUL at its Home Office.  Such crediting  shall be made separately for amounts
allocated to each Investment  Account.  The number of Accumulation Units in each
Investment  Account  credited to each  Participant  Account as of any  Valuation
Period shall be determined by dividing the amounts allocated to that In vestment
Account for that  Participant  Account as of such Valuation Period by the dollar
value of one  Accumulation  Unit in that  Investment  Account as of the close of
business on the applicable  Valuation Period.  The number of Accumulation  Units
thus  determined  shall not be  changed by any  subsequent  change in the dollar
value of the Accumulation Units.


The  value of an  Accumulation  Unit in the AUL  American  Equity,  Bond,  Money
Market, and Managed Investment Accounts was established at $1.00 as of April 12,
1990.  The  value  of an  Accumulation  Unit  in any  other  Investment  Account
available under the Contract shall be established at $1.00 as of the date of the
first deposit to such Investment  Account.  The value of an Accumulation Unit in
each Investment  Account as of any Valuation  Period  thereafter is equal to the
dollar  value of one  Accumulation  Unit in  that  Investment  Account as of the
immediately  preceding Valuation Period multiplied by the Net Investment Factor,
as defined below, for that Investment  Account for the current Valuation Period.
The  value  of an  Accumulation  Unit  for  each  Investment  Account  shall  be
determined  for each  Valuation  Period before  giving effect to any  additions,
withdrawals, or transfers. After such determination, the additions, withdrawals,
or transfers which are effective as of that day shall then be made.


The Net Investment  Factor for each Investment  Account for any Valuation Period
is determined by dividing (a) by (b), and then subtracting (c) from that result,
where:

(a)  is equal to:

<PAGE>

     (1)  the net  asset  value  of a  Portfolio  share  held in the  Investment
          Account determined as of the end of the current Valuation Period, plus


     (2)  the per share  amount of any dividend or other  distribution,  if any,
          paid by the Portfolio  during the current  Valuation  Period,  plus or
          minus

     (3)  any credit or charge for any taxes paid or reserved  for by AUL during
          the  current  Valuation  Period  which  are  determined  by  AUL to be
          attributable to operation of the Investment Account;

(b)  is the net asset value of a Portfolio share held in the Investment  Account
     determined as of the end of the immediately preceding Valuation Period; and

(c)  is a daily charge factor  determined by AUL to reflect the charges assessed
     against  the assets of the  Investment  Account for  mortality  and expense
     risks, as authorized under "Other Charges" below.

The value of each  Participant  Account's share of any Investment  Account as of
any Valuation Date shall be determined by multiplying the Participant  Account's
aggregate  Accumulation  Units in that  Investment  Account as of such Valuation
Date by the dollar value of one Accumulation Unit in that Investment  Account as
of such Valuation  Date.  The value of the  Participant  Account's  share of any
Investment  Account as of any date other than a  Valuation  Date is equal to the
value of its share of that Investment  Account as of the  immediately  preceding
Valuation Date.

                                 OTHER CHARGES

AUL shall deduct a daily  mortality  risk charge and a daily expense risk charge
equal to the daily equivalent of an annual  combined charge of 1.25% against the
average  daily net assets of each  Investment  Account.  These  charges shall be
reflected in the Net Investment Factor as defined above.

A Mutual Fund shall pay any investment  advisory fee and certain other expenses,
which may include its operational and organizational  expenses,  as described in
the current prospectus for that Mutual Fund as it may be amended or supplemented
from time to time.  These  expenses  may vary  from year to year.  The net asset
value of each Portfolio reflects such investment advisory fee and other expenses
which are deducted from the assets of such Portfolio.

AUL shall deduct an administrative charge per Contract year quarter equal to the
lesser  of $0.00  or 0.5% of the  Account  Value  on the  last day of each  such
quarter  from each  Participant  Account in existence on such day for so long as
the  Participant  Account is  in effect  during the  Accumulation  Period.  This
charge is to be prorated among each subaccount of the Participant  Account which
corresponds  to each  Investment  Option  utilized  under the  Contract  by that
Participant Account.
<PAGE>


AUL  reserves  the right to deduct a charge for each  transfer  transaction,  to
deduct the appropriate  premium tax charge, or to deduct the appropriate charges
for federal, state, or local income taxes incurred  by AUL that are attributable
to the Variable Account and its Investment Accounts.
Voting:

(a)  AUL is  the  legal  owner  of the  shares  of a  Mutual  Fund  held  by the
     Investment  Accounts of the Variable  Account.  AUL shall  exercise  voting
     rights  attributable to the shares of each Portfolio held in the Investment
     Accounts  at any regular and  special  meetings  of the  shareholders  of a
     Mutual Fund on matters  requiring  shareholder  voting under The Investment
     Company Act of l940 or other  applicable  laws.  AUL shall  exercise  these
     voting rights based on instructions received from persons having the voting
     interest in  corresponding  Investment  Accounts of the  Variable  Account.
     However,  if The Investment  Company Act of l940 or any  regulations  there
     under should be amended,  or if the present  interpretation  thereof should
     change,  and as a result AUL  determines  that it is  permitted to vote the
     shares of a Mutual  Fund in its own right,  it may elect to do so. AUL will
     vote shares of any Investment  Account,  if any, that it owns  beneficially
     in its own  discretion,  except  that if a Mutual Fund offers its shares to
     any insurance  company  separate account that funds variable life insurance
     contracts  or if  otherwise  required by applicable law, AUL  will vote its
     own  shares in the same  proportion  as the  voting  instructions  that are
     received  in  a  timely  manner  for  contracts  and  Participant  Accounts
     participating in the Investment Account.

(b)  The  persons  having  the  voting  interest  under  this  contract  are the
     Participants.

(c)  Voting  rights  attributable  to the  Contract  for which no timely  voting
     instructions  are received  will be voted by AUL in the same  proportion as
     the  voting  instructions  which are  received  in a timely  manner for all
     contracts  and  Participant  Accounts   participating  in  that  Investment
     Account.

(d)  Neither the Variable Account nor AUL is under any duty to inquire as to the
     instructions received or the authority of  Contractholders,  Participants,
     or others to instruct the voting of Mutual Fund shares.

(e)  Every person or entity having such voting rights shall receive such reports

     required by applicable federal law.

                                    ADDENDUM
                                     TO THE
                                   CERTIFICATE
                        ISSUED TO THE PARTICIPANT IN THE
                               AUL AMERICAN SERIES
                    TDA MULTIPLE-FUND GROUP VARIABLE ANNUITY
                    CONTRACT NUMBER GA XX,XXX (THE CONTRACT)
                                    ISSUED BY
                  AMERICAN UNITED LIFE INSURANCE COMPANY (AUL)
                                       TO
                        ABC COMPANY (THE CONTRACTHOLDER)

   The Effective Date of this Amendment is the date that it is signed by AUL.

Pursuant to this Addendum,  the  corresponding  provisions of the  Participant's
Certificate  under the Contract are hereby deleted and the following  provisions
are substituted in lieu thereof:

"Investment  Account"  means  each  subaccount  of  the  Variable  Account  made
available  to  the  Contractholder  by AUL and  identified  in Schedule A of the
Contract.  Schedule A of the Contract may be amended by AUL from time to time as
described in "Addition,  Deletion,  or  Substitution  of  Investments."  Amounts
allocated to any  Investment  Account  identified  in Schedule A of the Contract
shall be  invested  in the shares of the  corresponding  Mutual  Fund  Portfolio
listed in the current prospectus for the Variable Account.

"Mutual Fund" means the AUL American Series Fund, Inc., a diversified,  open-end
management  investment  company  registered under The Investment  Company Act of
l940, and any other such open-end  management  investment company made available
by AUL.

"Portfolio"  means a series of a  particular  Mutual Fund as  described  in that
prospectus  for  that  Mutual  Fund,  as  such  prospectus  may  be  amended  or
supplemented from time to time.

Addition, Deletion, or Substitution of Investments:

(a)  AUL reserves the right,  subject to compliance with applicable law, to make
     additions to,  deletions from,  substitution  for, or combinations  of, the
     securities that are held by the Variable Account or any Investment  Account
     or that the Variable  Account or any Investment  Account may purchase.  AUL
     reserves  the  right  to  eliminate  the  shares  of any  of  the  eligible
     Portfolios and to substitute  shares of, or interests in, another Portfolio
     of the AUL American  Series Fund,  Inc.,  of another  open-end,  registered
     investment  company,  or  other  investment  vehicle,  for  shares  already
     purchased  or to be  purchased  in the future  under the  Contract,  if the
     shares  of any or all  eligible  Portfolios  are no  longer  available  for
     investment,  or if, in AUL's  judgment,  further  investment  in any or all
     eligible  Portfolios  becomes  inappropriate in view of the purposes of the
     Variable Account or the Contract.  Where required under applicable law, AUL
     will not  substitute  any shares in the Variable  Account or any Investment
     Account  without  notice,  Participant  approval,  or prior approval of the
     Securities and Exchange Commission or a state insurance  commissioner,  and
     without following the filing or other procedures  established by applicable
     state  insurance  regulators.  Nothing  contained  herein shall prevent the
     Variable  Account  from  purchasing  other  securities  for other series or
     classes of contracts, or from effecting a conversion between series or

p-12834.add.1

<PAGE>

     classes  of  contracts  on  the  basis  of  requests  made by a majority of
     participants or as permitted by federal law.

(b)  AUL reserves the right to establish additional Investment Accounts, each of
     which would invest in the corresponding Mutual Fund Portfolio listed in the
     current  prospectus  for the Variable  Account,  or in other  securities or
     investment  vehicles.  AUL  reserves  the  right to  eliminate  or  combine
     existing Investment Accounts if, in its sole discretion, marketing, tax, or
     investment  conditions  so warrant.  AUL also reserves the right to provide
     other  Investment  Options  under the Contract at any time.  Subject to any
     required  regulatory  approvals,  AUL reserves the right to transfer assets
     from  any  Investment  Account  to  another  separate  account  of  AUL  or
     Investment Account.

(c)  In the event of any such  substitution  or change,  AUL may, by appropriate
     amendment,  make  such  changes  in the  Contract  as may be  necessary  or
     appropriate to reflect such  substitution or change. If deemed by AUL to be
     in the best interests of persons or entities having voting rights under the
     Contract,  the Variable Account may be operated as a management  investment
     company  under  The  Investment  Company  Act of  1940  or any  other  form
     permitted by law, it may be deregistered in the event such  registration is
     no longer  required under The Investment  Company Act of 1940, or it may be
     combined with other separate accounts of AUL or an affiliate  thereof.  AUL
     may take  such  action  as is  necessary  to  comply  with,  or to  obtain,
     exemptions  from the Securities and Exchange  Commission with regard to the
     Variable  Account.  Subject to compliance with applicable law, AUL also may
     combine one or more  Investment  Accounts  and may  establish a  committee,
     board, or other group to manage one or more aspects of the operation of the
     Variable Account.

Withdrawal Benefits:

(a)  (6)  Effective  January 1, 1993,  if,  as  provided  in  Internal  Revenue
          Code  Regulation  Section  1.403(b)-2T  Q&A-2,  the distributee of any
          eligible  rollover  distribution  elects to have the distribution paid
          directly to an eligible  retirement  plan (as defined in Q&A-1 of that
          Section)  and  specifies  the  eligible  retirement  plan to which the
          distribution  is to be paid,  then the  distribution  shall be paid to
          that eligible retirement plan in a direct rollover.

(d)  The Account Value to be applied  shall be  determined as of the  applicable
     Valuation  Date  determined in (c) above.  If the entire Account Value of a
     Participant  Account  is  withdrawn,  the  Participant  shall  be paid  the
     Withdrawal Value. If the Participant  requests that a specified  percentage
     or dollar amount be paid to the  Participant,  AUL shall  withdraw from the
     Participant Account an amount equal to the dollar amount to be paid divided
     by the  difference  between 1 and the decimal  equivalent of the applicable
     Withdrawal  Charge.  Notwithstanding  the previous  sentence,  in the first
     Contract year in which a  Participant  Account is  established,  and in the
     next  succeeding  Contract  year,  the  Participant  may withdraw from that
     Participant  Account  up to 10% of the  sum of the  Account  Value  of that
     Participant  Account,  determined  as  of  the  last  Contract  anniversary
     preceding the request for the withdrawal,  plus  Contributions  made during
     the applicable Contract year, without application of any Withdrawal Charge.
     In any subsequent  Contract year,  the  Participant  may withdraw from that
     Participant  Account  up to 10% of the  Account  Value of that  Participant
     Account,  determined  as of the last  Contract  anniversary  preceding  the
     request for the withdrawal,  without  application of any Withdrawal Charge.
     Also,  where a Participant  has  outstanding  loans under the  Contract,  a
     partial  withdrawal by a Participant  from the Fixed Interest Account shall
     be permitted only to the extent that the

p-12834.add.2
<PAGE>

     remaining Withdrawal  Value  of  the  Participant Account held in the Fixed
     Interest  Account  equals  twice the total of the Participant's outstanding
     loans under that Participant Account.

                                   VALUATIONS

All assets of each  Portfolio  shall be valued as provided in the prospectus for
the applicable  Mutual Fund as such  prospectus  may be amended or  supplemented
from time to time.

Any  amounts  that are  allocated  to any  Investment  Account  on  behalf  of a
Participant  shall  be  credited  to his  Participant  Account  in the  form  of
Accumulation  Units on the basis of the value of such  units in that  Investment
Account as of the end of the Valuation Period on which such amounts are received
by AUL at its Home Office.  Such crediting  shall be made separately for amounts
allocated to each Investment  Account.  The number of Accumulation Units in each
Investment  Account  credited to each  Participant  Account as of any  Valuation
Period shall be determined by dividing the amounts allocated to that In vestment
Account for that  Participant  Account as of such Valuation Period by the dollar
value of one  Accumulation  Unit in that  Investment  Account as of the close of
business on the applicable  Valuation Period.  The number of Accumulation  Units
thus  determined  shall not be  changed by any  subsequent  change in the dollar
value of the Accumulation Units.

The  value of an  Accumulation  Unit in the AUL  American  Equity,  Bond,  Money
Market, and Managed Investment Accounts was established at $1.00 as of April 12,
1990.  The  value  of an  Accumulation  Unit  in any  other  Investment  Account
available under the Contract shall be established at $1.00 as of the date of the
first deposit to such Investment  Account.  The value of an Accumulation Unit in
each Investment  Account as of any Valuation  Period  thereafter is equal to the
dollar  value of one  Accumulation  Unit in that  Investment  Account  as of the
immediately  preceding Valuation Period multiplied by the Net Investment Factor,
as defined below, for that Investment  Account for the current Valuation Period.
The  value  of an  Accumulation  Unit  for  each  Investment  Account  shall  be
determined  for each  Valuation  Period before  giving effect to any  additions,
withdrawals, or transfers. After such determination, the additions, withdrawals,
or transfers which are effective as of that day shall then be made.

The Net Investment  Factor for each Investment  Account for any Valuation Period
is determined by dividing (a) by (b), and then subtracting (c) from that result,
where:

(a)  is equal to:

     (1)  the net  asset  value  of a  Portfolio  share  held in the  Investment
          Account determined as of the end of the current Valuation Period, plus

     (2)  the per share  amount of any dividend or other  distribution,  if any,
          paid by the Portfolio  during the current  Valuation  Period,  plus or
          minus

     (3)  any credit or charge for any taxes paid or reserved  for by AUL during
          the  current  Valuation  Period  which  are  determined  by  AUL to be
          attributable to operation of the Investment Account;

(b)  is the net asset value of a Portfolio share held in the Investment  Account
     determined as of the end of the immediately preceding Valuation Period; and

p-12834.add.3
<PAGE>

(c)  is a daily charge factor  determined by AUL to reflect the charges assessed
     against  the assets of the  Investment  Account for  mortality  and expense
     risks, as authorized under "Other Charges" below.

The value of each  Participant  Account's share of any Investment  Account as of
any Valuation Date shall be determined by multiplying the Participant  Account's
aggregate  Accumulation  Units in that  Investment  Account as of such Valuation
Date by the dollar value of one Accumulation Unit in that Investment  Account as
of such Valuation  Date.  The value of the  Participant  Account's  share of any
Investment  Account as of any date other than a  Valuation  Date is equal to the
value of its share of that Investment  Account as of the  immediately  preceding
Valuation Date.

                                  OTHER CHARGES

AUL shall deduct a daily  mortality  risk charge and a daily expense risk charge
equal to the daily  equivalent of an annual combined charge of 1.25% against the
average  daily net assets of each  Investment  Account.  These  charges shall be
reflected in the Net Investment Factor as defined above.

A Mutual Fund shall pay any investment  advisory fee and certain other expenses,
which may include its operational and organizational  expenses,  as described in
the current prospectus for that Mutual Fund as it may be amended or supplemented
from time to time.  These  expenses  may vary  from year to year.  The net asset
value of each Portfolio reflects such investment advisory fee and other expenses
which are deducted from the assets of such Portfolio.

AUL shall deduct an administrative charge per Contract year quarter equal to the
lesser  of $7.50  or 0.5% of the  Account  Value  on the  last day of each  such
quarter  from each  Participant  Account in existence on such day for so long as
the Participant Account is in effect during the Accumulation Period. This charge
is to be  prorated  among  each  subaccount  of the  Participant  Account  which
corresponds  to each  Investment  Option  utilized  under the  Contract  by that
Participant Account.

AUL  reserves  the right to deduct a charge for each  transfer  transaction,  to
deduct the appropriate  premium tax charge, or to deduct the appropriate charges
for federal,  state, or local income taxes incurred by AUL that are attributable
to the Variable Account and its Investment Accounts.

Voting:

(a)  AUL is  the  legal  owner  of the  shares  of a  Mutual  Fund  held  by the
     Investment  Accounts of the Variable  Account.  AUL shall  exercise  voting
     rights  attributable to the shares of each Portfolio held in the Investment
     Accounts  at any regular and  special  meetings  of the  shareholders  of a
     Mutual Fund on matters  requiring  shareholder  voting under The Investment
     Company Act of l940 or other  applicable  laws.  AUL shall  exercise  these
     voting rights based on instructions received from persons having the voting
     interest in  corresponding  Investment  Accounts of the  Variable  Account.
     However,  if  The  Investment  Company  Act  of  l940  or  any  regulations
     thereunder  should be  amended,  or if the present  interpretation  thereof
     should change,  and as a result AUL determines that it is permitted to vote
     the shares of a Mutual  Fund in its own  right,  it may elect to do so. AUL
     will  vote  shares  of  any  Investment  Account,  if  any,  that  it  owns
     beneficially in its own discretion, except that if a Mutual Fund offers its
     shares to any insurance  company  separate account that funds variable life
     insurance  contracts or if otherwise  required by applicable  law, AUL will
     vote its own shares in the same proportion as the voting  instructions that
     are received in a timely  manner for  contracts  and  Participant  Accounts
     participating in the Investment Account.

p-12834.add.4
<PAGE>

(b)  The  persons  having  the  voting  interest  under  the  Contract  are  the
     Participants.

(c)  Voting  rights  attributable  to the  Contract  for which no timely  voting
     instructions  are received  will be voted by AUL in the same  proportion as
     the  voting  instructions  which are  received  in a timely  manner for all
     contracts  and  Participant  Accounts   participating  in  that  Investment
     Account.

(d)  Neither the Variable Account nor AUL is under any duty to inquire as to the
     instructions received or the authority of Contractholders, Participants, or
     others to instruct the voting of Mutual Fund shares.

(e)  Every person or entity having such voting rights shall receive such reports
     or prospectuses  concerning the Variable Account or a Mutual Fund as may be
     required by applicable federal law.

                    CONTRACT NUMBER GA XX,XXX (THE CONTRACT)
                                    ISSUED BY
                  AMERICAN UNITED LIFE INSURANCE COMPANY (AUL)
                                       TO
                        ABC COMPANY (THE CONTRACTHOLDER)


                    The Effective Date of this Amendment is.

AUL and the Contractholder  hereby agree, by signing below, that the Contract is
hereby amended as follows:

By  deleting  the last  paragraph  of the  face  page  and by  substituting  the
following last paragraph in lieu thereof:

ACCUMULATION  UNITS IN ANY  INVESTMENT  ACCOUNT  FOR WHICH THIS  CONTRACT  MAKES
PROVISION MAY INCREASE OR DECREASE IN DOLLAR VALUE  ACCORDING TO THE  INVESTMENT
PERFORMANCE OF THE UNDERLYING ASSETS IN THE CORRESPONDING  MUTUAL FUND OR MUTUAL
FUND PORTFOLIO IN WHICH THE INVESTMENT ACCOUNT INVESTS. THE VALUE OF SUCH ASSETS
AND ACCUMULATION  UNITS IS NOT GUARANTEED.  ARTICLE 5 OF THIS CONTRACT  EXPLAINS
THE VALUATION OF SUCH ASSETS AND ACCUMULATION UNITS.

By deleting the  corresponding  Sections or  Subsections  of the Contract and by
substituting  the following  Sections or  Subsections  in lieu  thereof,  and by
making  any  required  corresponding  changes  in the Table of  Contents  of the
Contract:

1.6  "Contract  Anniversary" means the first day of the second Contract Year and
     each subsequent  Contract Year. Each Contract  Anniversary  after the First
     Contract Anniversary shall be the same day of the same month as the day and
     month  which is  stated  on the face  page of this  contract  for the First
     Contract Anniversary.

1.9  "Contributions"  means  amounts  paid to AUL from  time to time  by,  or on
     behalf of,  Participants,  including  amounts  transferred to this contract
     from another AUL group annuity contract,  which are credited to Participant
     Accounts maintained hereunder.

1.15 "Investment Account" means each subaccount of the Variable Account which is
     maintained  by AUL and  made  available  to the  Contractholder  by AUL and
     identified in Schedule A of the contract. Schedule A of the contract may be
     amended  by AUL from time to time as  described  in  Section  3.3.  Amounts
     allocated  to  any  Investment  Account  identified  in  Schedule  A of the
     contract shall be invested in the shares of the  corresponding  Mutual Fund
     or Mutual Fund Portfolio listed in the current  prospectus for the Variable
     Account.

p-12833.x.amd.1
<PAGE>


1.17 "Mutual  Fund" means the AUL  American  Series Fund,  Inc., a  diversified,
     open-end  management  investment  company  registered  under The Investment
     Company  Act of l940,  and any other such  open-end  management  investment
     company made available by AUL, as listed in Schedule A.


1.20 "Portfolio"  (also known as a "Mutual  Fund  Portfolio")  means a portfolio
     established within a particular Mutual Fund as described in that prospectus
     for that Mutual Fund,  as such  prospectus  may be amended or  supplemented
     from time to time.

1.24 "Withdrawal  Charge"  means a charge taken by AUL equal to a percentage  of
     the Account Value  withdrawn  pursuant to Section 4.8, where the percentage
     varies by the Participant Account Year in which the withdrawal is made. The
     first  Participant  Account Year begins on the date when AUL  establishes a
     Participant   Account  and  credits  the  initial   Contribution   for  the
     Participant, and ends on the day immediately preceding the next anniversary
     of such date. Each  Participant  Account Year thereafter  begins on such an
     anniversary  date  and  ends  on the day  immediately  preceding  the  next
     succeeding  anniversary  date.  The  Withdrawal  Charge  percentage  is  as
     follows:

                  During                               Withdrawal Charge
          Participant Account Years                        Percentage

                   1-5                                       8%
                   6-10                                      4%
               Thereafter                                    0%

However,  for any  Participant  who also  participates  in AUL  Series III group
annuity contract GA XX,XXX,  the initial Withdrawal Charge percentage under this
contract shall be equal to the Withdrawal  Charge  percentage  applicable to the
Participant  under the AUL Series I group annuity contract from which funds have
been  transferred  to such Series III contract,  determined  by AUL  immediately
prior to the date of such  transfer,  rounded down to the next whole  Withdrawal
Charge  percentage  if the  Withdrawal  Charge  percentage  under such  Series I
contract is a fractional  Withdrawal Charge percentage.  However, the Withdrawal
Charge  percentage  under this  paragraph  shall  never be greater  than 8%. The
Withdrawal  Charge  percentage  shall be  decreased  by 1% for  each  subsequent
Participant  Account  Year until the  Withdrawal  Charge  percentage  equals 4%.
(However,  if the applicable  Series I contract  Withdrawal Charge percentage is
less than 4%, it shall be rounded up to 4% in this contract.) This 4% Withdrawal
Charge  percentage shall be in effect during the next 6 consecutive  Participant
Account Years. Thereafter,  the Withdrawal Charge percentage shall be reduced to
0%.

In no event will the cumulative total of all Withdrawal Charges, including those
previously  assessed  against any amount  withdrawn from a Participant  Account,
exceed 9% of total Contributions allocated to that Participant Account.

3.1  Amount  of  Contributions:   (a)  Contributions  may  vary  in  amount  and
     frequency;  however,  when made,  they must be at least  equal to a minimum
     annual  Contribution of $200 per Participant in any full Contract Year. AUL
     may change the minimum annual Contribution  acceptable under this contract,
     but any such change shall apply only to individuals who become Participants
     on or after the date of the change.

p-12833.x.amd.2
<PAGE>

3.2  How Contributions Are Handled:

     (b)  Within any one  Participant  Account,  the amount so credited shall be
          allocated  to an  Investment  Option  in  increments  elected  by  the
          Participant  in a form  acceptable  to AUL.  If no  Investment  Option
          election  is made with  respect to a  particular  Contribution  to any
          Participant Account, AUL shall process such credits in accordance with
          the Investment Option election applicable to the immediately preceding
          Contribution. The Participant may change an Investment Option election
          with  respect  to future  allocations  to the  applicable  Participant
          Account by giving new Investment  Option  elections to AUL at its Home
          Office in a form acceptable to AUL.

     (c)  The initial  Contribution  for a  Participant  shall be  credited  and
          allocated  to the  Participant  Account  no later  than  the  close of
          business on the second  business day of AUL after the later of (1) the
          business day that AUL receives  the initial  Contribution  at its Home
          Office, or (2) the business day that AUL receives, at its Home Office,
          the data required to establish the Participant  Account,  instructions
          regarding the amount of the initial  Contribution for the Participant,
          and Investment Option elections regarding the initial Contribution.

     (d)  If  the  data  required  to  establish  a   Participant   Account  and
          instructions   regarding  the  amount  of  a   Contribution   for  the
          Participant  are not  received  by AUL at its  Home  Office  within  5
          business days after AUL first  receives that  Contribution,  AUL shall
          return  that  Contribution  to  the  contributing   party  unless  the
          contributing  party consents to AUL retaining that Contribution  until
          the earlier of (i) the date AUL  receives  such data and  instructions
          and,  therefore,  can  properly  allocate  that  Contribution  to  the
          Participant Account or (ii) 25 days from the date that Contribution is
          received by AUL.

     (e)  If the data required to establish a Participant Account, including any
          annuity  enrollment form required by AUL, and  instructions  regarding
          the amount of a Contribution for the Participant are received,  but an
          Investment  Option election for that  Participant is not received,  by
          AUL at its  Home  Office  as of  the  date  AUL  first  receives  that
          Contribution,  AUL shall allocate that  Contribution to the Investment
          Option election  identified in the  Participant's  annuity  enrollment
          form,  which is  generally  the AUL American  Money Market  Investment
          Account.  If AUL subsequently  receives the data required to establish
          the  Participant  Account,  instructions  regarding  the amount of the
          Contribution for the Participant,  and an Investment  Option election,
          AUL shall then  transfer  such  amounts  credited to the AUL  American
          Money Market Investment  Account or other Investment Option identified
          in the  Participant's  annuity  enrollment  form,  plus gains or minus
          losses  thereon,  to another  Investment  Option,  if such election so
          directs.

     (f)  Contributions for a Participant subsequent to the initial Contribution
          shall be  allocated  to the  Participant  Account  as of the  close of
          business  on the  later  of (1) the  Valuation  Period  in  which  AUL
          receives  that  Contribution  at its Home Office or (2) the  Valuation
          Period in which AUL receives, at its Home Office, the data required to
          establish the Participant Account,  instructions  regarding the amount
          of  that  Contribution  for the  Participant,  and  Investment  Option
          elections.

3.3  Addition, Deletion, or Substitution of Investments:

     (a)  AUL reserves the right,  subject to compliance with applicable law, to
          make additions to, deletions from,  substitution  for, or combinations
          of,  the  securities  that are  held by the  Variable  Account  or any
          Investment Account or that the Variable Account or any

p-12833.x.amd.3
<PAGE>

          Investment Account may  purchase.  AUL reserves the right to eliminate
          the  shares  of  any  of  the  eligible  Mutual  Funds  or Mutual Fund
          Portfolios  and  to  substitute  shares  of, or  interests in, another
          Portfolio of the AUL American Series Fund, Inc.,   another   open-end,
          registered  investment  company,  or  another  investment vehicle, for
          shares  already  purchased  or to be purchased in the future under the
          contract, if the shares of any or all eligible  Mutual Funds or Mutual
          Fund Portfolios   are no longer available for investment or if further
          investment  in  any  or  all  eligible  Mutual  Funds  or  Mutual Fund
          Portfolios  becomes  inappropriate  in  view  of  the  purposes of the
          Variable Account or the contract. Where required under applicable law,
          AUL will  not substitute  any  shares  in the Variable  Account or any
          Investment  Account  without  notice,  Participant  approval, or prior
          approval  of  the  Securities  and  Exchange   Commission  or  a state
          insurance  commissioner,  and without   following  the filing or other
          procedures  established  by  applicable  state  insurance  regulators.
          Nothing  contained  herein  shall  prevent  the Variable  Account from
          purchasing other securities for other series or  classes of contracts,
          or from effecting a conversion between series or classes of  contracts
          on the  basis of  requests  made by a majority of   participants or as
          permitted by federal law.

     (b)  AUL reserves the right to establish  additional  Investment  Accounts,
          each of which would invest in the corresponding  Mutual Fund or Mutual
          Fund  Portfolio  listed in the  current  prospectus  for the  Variable
          Account, or in other securities or investment  vehicles.  AUL reserves
          the right to  eliminate  or combine  existing  Investment  Accounts if
          marketing, tax, or investment conditions so warrant. AUL also reserves
          the right to provide other  Investment  Options under this contract at
          any time. Subject to any required regulatory  approvals,  AUL reserves
          the right to transfer  assets from any  Investment  Account to another
          separate account of AUL or Investment Account.

     (c)  In the  event  of  any  such  substitution  or  change,  AUL  may,  by
          appropriate  amendment,  make such changes in this  contract as may be
          necessary or appropriate to reflect such  substitution  or change.  If
          deemed  by AUL to be in the best  interests  of  persons  or  entities
          having voting rights under this contract,  the Variable Account may be
          operated  as a  management  investment  company  under The  Investment
          Company  Act of 1940 or any other  form  permitted  by law,  it may be
          deregistered  in the event  such  registration  is no longer  required
          under The  Investment  Company Act of 1940, or it may be combined with
          other separate accounts of AUL or an affiliate  thereof.  AUL may take
          such action as is necessary to comply with,  or to obtain,  exemptions
          from  the  Securities  and  Exchange  Commission  with  regard  to the
          Variable Account.  Subject to compliance with applicable law, AUL also
          may  combine  one or more  Investment  Accounts  and may  establish  a
          committee,  board, or other group to manage one or more aspects of the
          operation of the Variable Account.

3.4  Transfers:

     (a)  Subject to the  limitations of Section 3.5, the Participant may direct
          AUL, in a form acceptable to AUL, to transfer the amounts  credited to
          an  Investment  Option  to any  other  Investment  Option  during  the
          Accumulation  Period. Any transfer from an Investment Account shall be
          effective as of the close of business on the  Valuation  Date that AUL
          receives the Participant's transfer direction at its Home Office.

3.5  Limitations on Transfers:

     (a)  The  minimum  transfer  from the  Participant  Account's  share of any
          Investment  Option is the lesser of $500 or the Participant  Account's
          entire share of that Investment  Option as of the close of business on
          the Valuation  Date that AUL receives  that transfer  direction at its
          Home  Office.  However,  if  that  transfer  reduces  the  Participant
          Account's remaining

p-12833.x.amd.5
<PAGE>

          share  of  that  Investment  Option  to  less  than  $500, the  entire
          remaining share shall also be transferred.

     (b)  Amounts  transferred  from the Fixed  Interest  Account on behalf of a
          Participant  during  any  Contract  Year  shall not  exceed 20% of the
          Participant  Account's share of the Fixed Interest Account  determined
          as of the  later  of the  Contract  Date or the  Contract  Anniversary
          immediately  preceding the request for transfer.  Notwithstanding  the
          previous  sentence,  if the  Participant  Account's share of the Fixed
          Interest Account is less than $2,500 determined as of the later of the
          Contract Date or the Contract  Anniversary  immediately  preceding the
          request for transfer, the amount transferrable from the Fixed Interest
          Account  for  that  Contract  Year  is  the  lesser  of  $500  or  the
          Participant Account's entire share of the Fixed Interest Account as of
          the close of business on the  Valuation  Date that AUL  receives  that
          transfer  direction at its Home Office.  And if that transfer  reduces
          the  Participant  Account's  remaining  share  of the  Fixed  Interest
          Account to less than $500,  the entire  remaining  share shall also be
          transferred.

4.5  Minimum  Payments:  If the total  Account  Value is less than $2,000,  such
     value  (subject to Section 6.5 and minus any  outstanding  loan balances of
     the Participant and any unpaid expense charges on such loans) shall be paid
     in a lump sum to the  annuitant  rather than  annuitized  under the annuity
     options  provided in Section 4.2.  Additionally,  if the  proposed  monthly
     annuity  payment  should fall below  AUL's  periodically  adjusted  minimum
     monthly annuity payment,  AUL reserves the right to make payments on a less
     frequent basis (i.e.,  quarterly,  semiannually,  or annually), so that the
     actual annuity payment is equal to or greater than the established  minimum
     level,  or to pay the Account  Value  (subject to Section 6.5 and minus any
     outstanding loan balances of the Participant and any unpaid expense charges
     on such loans) in a single sum.

4.7  Death Benefits:

     (a)  Upon   receipt  of  written   instructions   from  the   Participant's
          beneficiary  (or, if  applicable,  the  secondary  beneficiary  of the
          Participant)  and  of  due  proof  of  the   Participant's   (and,  if
          applicable, the beneficiary's) death during the Accumulation Period at
          its Home Office, AUL shall apply the Account Value (subject to Section
          6.5, and minus the  Participant's  outstanding  loan balance,  if any,
          under this contract and any unpaid expense  charges due on such loans)
          of the  Participant  Account  for the  purpose  of  providing  a death
          benefit.  The  death  benefit  shall be paid to the  beneficiary  last
          properly  designated  in  writing  to AUL at its  Home  Office  by the
          Participant,  or, if there is no designated  beneficiary living on the
          date of the  Participant's  death, to the  Participant's  estate.  The
          Participant's  beneficiary  may also designate a  beneficiary.  If any
          beneficiary  dies  while  receiving  payments  and no  beneficiary  is
          designated to receive any remaining payments,  such remaining payments
          shall be made to the deceased beneficiary's estate.

     (b)  The  Account  Value  to be  applied  pursuant  to (a)  above  shall be
          determined as of the close of business on the Valuation  Date that AUL
          receives  a proper  withdrawal  request  (or due  proof of  death,  if
          received later), in a form acceptable to AUL, at its Home Office.

     (c)  (1)  The  benefit  shall  be  payable  in  accordance  with one of the
               following  provisions  as  elected  by  the  Participant  or  the
               beneficiary if the Participant did not make an election:

p-12833.x.amd.6
<PAGE>
               (i)  The entire  Account Value to be applied shall be paid to the
                    beneficiary  in a single sum or other method not provided in
                    (ii) below on or before  December  31 of the  calendar  year
                    which  contains  the  fifth  anniversary  of the date of the
                    Participant's death; or

               (ii) The benefit shall be paid as an annuity in  accordance  with
                    the Annuity  Options  shown in Section 4.2 over a period not
                    to exceed the life or life expectancy of the beneficiary. If
                    the beneficiary is not the  Participant's  surviving spouse,
                    the  annuity  must  begin on or  before  December  31 of the
                    calendar  year  immediately  following  the calendar year in
                    which  the  Participant  died.  If  the  beneficiary  is the
                    Participant's  surviving spouse,  the annuity need not begin
                    before  December  31 of  the  calendar  year  in  which  the
                    Participant would have attained age 70 1/2.

          (2)  If a Participant dies on or after his Annuity  Commencement Date,
               any interest remaining under the Annuity Option selected shall be
               paid at least as rapidly as prior to the Participant's death.

          (3)  If  payment  is to be made in a cash lump sum,  payment  shall be
               made within 7 days of the date of valuation,  as determined above
               in this  Section,  except as AUL may be  permitted  to defer such
               payment  of  amounts   derived  from  the  Variable   Account  in
               accordance with the provisions of federal  securities laws. Also,
               AUL reserves the right to defer the payment of amounts  withdrawn
               from the Fixed  Interest  Account  for a period of up to 6 months
               after AUL receives proper instructions at its Home Office.

4.8  Withdrawal  Benefits: A Participant may direct AUL at its Home Office, in a
     form  acceptable  to AUL,  to withdraw  all or a portion of the  Withdrawal
     Value of his Participant Account, subject to the following provisions:

     (a)  Amounts  attributable  to amounts  held as of December  31, 1988 under
          another Code Section 403(b) annuity contract may be withdrawn.

     (b)  Amounts  attributable to  Contributions  made other than pursuant to a
          salary  reduction  agreement  (within  the  meaning  of  Code  Section
          402(g)(3)(C)) may be withdrawn.

     (c)  Amounts  attributable  to  Contributions  made  pursuant  to a  salary
          reduction agreement (within the meaning of Code Section  402(g)(3)(C))
          may be withdrawn, provided that any distribution of such amounts shall
          not occur  until  the  Participant  has  either  attained  age 59 1/2,
          separated  from service,  become  totally  disabled (as defined by the
          Internal  Revenue  Service),  or experienced a hardship (as defined by
          the  Internal  Revenue  Service).  However,  in the case of a hardship
          withdrawal,  any  gain  credited  to  such  Contributions  may  not be
          withdrawn.

     (d)  Withdrawal  of any  amount  from this  contract  which is  transferred
          directly  by AUL  pursuant  to  Participant  instructions  to  another
          tax-deferred annuity funding vehicle under applicable Internal Revenue
          Service rules and  regulations  shall be subject to application of the
          Withdrawal Charge.

p-12833.x.amd.7
<PAGE>
     (e)  If,  as  provided  in  Internal   Revenue  Code   Regulation   Section
          1.403(b)-2T   Q&A-2,   the   distributee  of  any  eligible   rollover
          distribution  elects  to have the  distribution  paid  directly  to an
          eligible  retirement  plan (as defined in Q&A-1 of that  Section)  and
          specifies the eligible retirement plan to which the distribution is to
          be  paid,  then  the  distribution  shall  be paid  to  that  eligible
          retirement plan in a direct rollover.

     (f)  AUL  shall  not  be  responsible   for   determining  a  Participant's
          compliance with the requirements  above. Any withdrawal  request shall
          include  certification  as to  the  purpose  of  the  withdrawal.  The
          Participant  assumes full  responsibility for determining  whether the
          withdrawal is permitted under applicable law. AUL may rely solely upon
          the representations of the Participant made in the withdrawal request.

     (g)  Withdrawals  from a  Participant  Account's  share  of any  Investment
          Option may not be made in an amount  less than the  smaller of $500 or
          the Participant  Account's entire share of the Investment Option. If a
          withdrawal  reduces the  Participant  Account's share of an Investment
          Option to less than $500, such remaining share shall also be withdrawn
          (except  for  amounts   prohibited  from  being  distributed   because
          Subsection (c) above is not met).

     (h)  A withdrawal  request shall be effective,  and the Account Value to be
          applied pursuant to this Section shall be determined,  as of the close
          of  business  on  the  Valuation  Date  that  AUL  receives  a  proper
          withdrawal  request,  in a form acceptable to AUL, at its Home Office.
          If  it  is  necessary  to  withdraw  the  entire  Account  Value  of a
          Participant  Account to make a lump-sum cash payment,  the amount paid
          shall equal the Withdrawal Value, minus any Section 6.5 charges. If it
          is not  necessary  to withdraw the entire  Account  Value to make such
          payment, AUL shall reduce the Account Value of the Participant Account
          by an amount  sufficient  to make the cash  payment  requested  and to
          cover  the   Withdrawal   Charge   and  any   Section   6.5   charges.
          Notwithstanding  the previous sentence,  in the first Contract Year in
          which a  Participant  Account  is  established,  the  Participant  may
          withdraw  from that  Participant  Account  up to 10% of the sum of the
          Account Value of that Participant  Account (determined as of the later
          of the Contract Date or the Contract Anniversary immediately preceding
          the request for the withdrawal)  plus  Contributions  made during that
          Contract Year,  without  application of the Withdrawal  Charge. In the
          next succeeding  Contract Year, the Participant may also withdraw from
          that Participant  Account up to 10% of the sum of the Account Value of
          that Participant  Account  (determined as of the Contract  Anniversary
          immediately   preceding   the   request  for  the   withdrawal)   plus
          Contributions made during that Contract Year,  without  application of
          the  Withdrawal   Charge.   In  any  subsequent   Contract  Year,  the
          Participant  may withdraw from that  Participant  Account up to 10% of
          the Account Value of that  Participant  Account  (determined as of the
          Contract  Anniversary   immediately  preceding  the  request  for  the
          withdrawal) without application of the Withdrawal Charge.  Also, where
          a Participant  has  outstanding  loans under this contract,  a partial
          withdrawal by a Participant  from the Fixed Interest  Account shall be
          permitted  only to the extent that the remaining  Withdrawal  Value of
          the  Participant  Account held in the Fixed  Interest  Account  equals
          twice the total of the  Participant's  outstanding  loans  under  this
          contract.

     (i)  AUL shall pay any cash lump sum to the Participant  within 7 days from
          the appropriate  Valuation Date as determined in Subsection (h) above,
          except  as AUL may be  permitted  to defer  such  payment  of  amounts
          withdrawn  from the Variable  Account in accordance  with  appropriate
          provisions of the federal  securities  laws. AUL reserves the right to
          defer

p-12833.x.amd.8
<PAGE>

          the payment of amounts withdrawn from the Fixed Interest Account for a
          period of up to 6 months after AUL receives the withdrawal  request at
          its Home Office.

     (j)  Withdrawals  from a Participant  Account's share of the Fixed Interest
          Account shall be made on a  first-in/first-out  basis so that all or a
          portion of the amounts credited to the Participant  Account's share of
          the Fixed  Interest  Account  (other than amounts which are prohibited
          from being distributed  because Subsection (c) above is not met) which
          have been on deposit  for the longest  period of time,  as well as the
          interest credited thereon, shall be withdrawn first.

5.1  Valuation  of Mutual Fund or Mutual Fund  Portfolio  Assets:  All assets of
     each Mutual Fund or Mutual  Fund  Portfolio  shall be valued as provided in
     the prospectus  for the applicable  Mutual Fund or Mutual Fund Portfolio as
     such prospectus may be amended or supplemented from time to time.

5.2  Accumulation  Units:  Any amounts  allocated to any  Investment  Account on
     behalf of a Participant shall be credited to his Participant Account in the
     form of Accumulation  Units on the basis of the value of such units in that
     Investment  Account as of the later of (1) the end of the Valuation  Period
     on which such amounts are received by AUL at its Home Office or (2) the end
     of the  Valuation  Period  on which  the data  required  to  establish  the
     Participant  Account and allocate such amounts to the  Participant  Account
     and to Investment Options are received by AUL at its Home Office.  However,
     if the initial  Contribution  for a  Participant  is allocated  pursuant to
     Section 3.2(b)(1) on the next succeeding  Valuation Period,  the unit value
     as of the end of that Valuation  Period shall be used. Such crediting shall
     be made separately for amounts  allocated to each Investment  Account.  The
     number of Accumulation  Units in each Investment  Account  credited to each
     Participant  Account as of any  Valuation  Period  shall be  determined  by
     dividing  the  amounts  allocated  to  that  Investment  Account  for  that
     Participant  Account as of such Valuation Period by the dollar value of one
     Accumulation Unit in that Investment Account as of the close of business on
     the applicable  Valuation  Period.  The number of  Accumulation  Units thus
     determined  shall not be  changed  by any  subsequent  change in the dollar
     value of the Accumulation Units.

5.3  Value of Accumulation  Units: The value of an Accumulation  Unit in the AUL
     American Equity,  Bond, Money Market, and Managed  Investment  Accounts was
     established  at $1.00 as of April 12,  1990.  The value of an  Accumulation
     Unit in any other Investment Account available under this contract shall be
     established at $1.00 as of the date of the first deposit to such Investment
     Account. The value of an Accumulation Unit in each Investment Account as of
     any  Valuation  Period  thereafter  is  equal  to the  dollar  value of one
     Accumulation  Unit  in  that  Investment  Account  as  of  the  immediately
     preceding  Valuation  Period  multiplied by the Net Investment  Factor,  as
     defined  in  Section  5.4,  for that  Investment  Account  for the  current
     Valuation  Period.  The value of an  Accumulation  Unit for each Investment
     Account shall be determined for each Valuation  Period before giving effect
     to any additions,  withdrawals, or transfers. After such determination, the
     additions,  withdrawals,  or transfers  which are  effective as of that day
     shall then be made.

5.4  Determining the Net Investment  Factor:  The Net Investment Factor for each
     Investment  Account for any Valuation  Period is determined by dividing (a)
     by (b), and then subtracting (c) from that result, where:

     (a)  is equal to:
p-12833.x.amd.9
<PAGE>
          (1)  the net asset  value of a Mutual  Fund or Mutual  Fund  Portfolio
               share held in the Investment  Account determined as of the end of
               the current Valuation Period, plus

          (2)  the per share  amount of any dividend or other  distribution,  if
               any, paid by the Mutual Fund or Mutual Fund Portfolio  during the
               current Valuation Period, plus or minus

          (3)  any credit or charge for any taxes  paid or  reserved  for by AUL
               during the current  Valuation  Period which are determined by AUL
               to be attributable to operation of the Investment Account;

     (b)  is the net asset value of a Mutual Fund or Mutual Fund Portfolio share
          held  in  the  Investment  Account  determined  as of  the  end of the
          immediately preceding Valuation Period; and

     (c)  is a daily  charge  factor  determined  by AUL to reflect  the charges
          assessed  against the assets of the  Investment  Account for mortality
          and expense risks, as authorized by Section 6.1.

6.1  Mortality Risk and Expense Risk Charges: AUL shall deduct a daily mortality
     risk charge and a daily  expense risk charge equal to the daily  equivalent
     of an annual  combined charge of 1.25% against the average daily net assets
     of each  Investment  Account.  These  charges shall be reflected in the Net
     Investment Factor as provided in Section 5.4(c).

6.2  Mutual Fund or Mutual Fund Portfolio Expenses: A Mutual Fund or Mutual Fund
     Portfolio shall pay any investment advisory fee and certain other expenses,
     which may include its ordinary operational and organizational  expenses, or
     any extraordinary expenses, as described in the current prospectus for that
     Mutual Fund or Mutual Fund  Portfolio as it may be amended or  supplemented
     from time to time. These expenses may vary from year to year. The net asset
     value of each Mutual  Fund or Mutual Fund  Portfolio  share  reflects  such
     investment  advisory fee and other  expenses  which are  deducted  from the
     assets of such Mutual Fund or Mutual Fund Portfolio.

6.6  Reduction or Waiver of Certain Charges:  AUL may reduce or waive the amount
     of the Withdrawal Charge or the administrative charge discussed  in Section
     6.3 where the  expenses  associated  with the sale of this  contract or the
     administrative  costs  associated with this contract are reduced,  or where
     this  contract is sold to the  directors  or employees of AUL or any of its
     affiliates,  or to  directors or any  employees of the AUL American  Series
     Fund, Inc.

8.2  AUL's Annual Statement: No provision or condition of this contract shall be
     deemed to control, determine, or modify any annual statement of AUL made to
     any insurance department, contractholder, regulatory body, or other person,
     nor  shall  anything  in  such  annual  statement  be  deemed  to  control,
     determine,  or modify the valuation provided for in this contract,  nor the
     values determined, nor the market, book, or other value of any asset in any
     Investment Account or Mutual Fund or Mutual Fund Portfolio,  nor any of the
     other provisions and conditions of this contract.

8.8  Election,  Notice,  or Direction  Requirements:  Wherever in this  contract
     reference is made to the  Contractholder or Participant making a request or
     giving notice or direction,  such request,  notice, or direction must be in
     writing, or in a form otherwise acceptable to AUL, and must be submitted

     to and received by AUL at its Home Office before becoming effective, unless
     the Contractholder or Participant is otherwise directed by AUL.

8.15 Voting:

     (a)  AUL is the legal  owner of the shares of a Mutual  Fund or Mutual Fund
          Portfolio held by the Investment  Accounts of the Variable Account. In
          accordance  with its view of present  law, AUL shall  exercise  voting
          rights  attributable  to the shares of each Mutual Fund or Mutual Fund
          Portfolio held in the  Investment  Accounts at any regular and special
          meetings of the  shareholders  of a Mutual  Fund on matters  requiring
          shareholder  voting under The Investment  Company Act of l940 or other
          applicable  laws.  AUL shall  exercise  these  voting  rights based on
          instructions  received  from  persons  having the voting  interest  in
          corresponding Investment Accounts of the Variable Account. However, if
          The  Investment  Company  Act of  l940 or any  regulations  thereunder
          should be amended,  or if the present  interpretation  thereof  should
          change,  and as a result AUL  determines  that it is permitted to vote
          the shares of a Mutual Fund or Mutual Fund Portfolio in its own right,
          it may elect to do so. AUL will vote shares of any Investment Account,
          if any, that it owns  beneficially in its own discretion,  except that
          if a Mutual  Fund or Mutual  Fund  Portfolio  offers its shares to any
          insurance  company separate account that funds variable life insurance
          contracts or if otherwise  required by  applicable  law, AUL will vote
          its own shares in the same proportion as the voting  instructions that
          are received in a timely manner for contracts and Participant Accounts
          participating in the Investment Account.

     (b)  The persons  having the voting  interest  under this  contract are the
          Participants.  Unless otherwise required by applicable law, the number
          of Mutual  Fund or Mutual  Fund  Portfolio  shares as to which  voting
          instructions  may be given to AUL is  determined by dividing the value
          of all of  the  Accumulation  Units  of the  corresponding  Investment
          Account  attributable to this contract on a particular date by the net
          asset value per share of that Mutual Fund or Mutual Fund  Portfolio as
          of the same  date.  Fractional  votes will be  counted.  The number of
          votes as to which voting  instructions may be given will be determined
          as of the date coincident with the date  established by the applicable
          Mutual  Fund or Mutual Fund  Portfolio  for  determining  shareholders
          eligible to vote at the meeting of that  Mutual  Fund.  If required by
          the Securities and Exchange  Commission or under any contract with any
          of the Mutual  Funds made  available by AUL, AUL reserves the right to
          determine in a different fashion the voting rights attributable to the
          shares of a Mutual Fund or Mutual Fund Portfolio.

     (c)  Voting rights attributable to this contract for which no timely voting
          instructions  are received will be voted by AUL in the same proportion
          as the voting  instructions  which are received in a timely manner for
          all  contracts  and  Participant   Accounts   participating   in  that
          Investment Account.

     (d)  Neither the  Variable  Account nor AUL is under any duty to inquire as
          to the  instructions  received or the  authority  of  Contractholders,
          Participants,  or  others to  instruct  the  voting of Mutual  Fund or
          Mutual Fund Portfolio shares.

     (e)  Every person or entity  having such voting  rights shall  receive such
          reports or  prospectuses  concerning the Variable  Account or a Mutual
          Fund or Mutual Fund Portfolio as may be required by applicable federal
          law.

                  AMERICAN UNITED LIFE INSURANCE COMPANY (AUL)

                              (THE CONTRACTHOLDER)

                    The Effective Date of this Amendment is .

AUL and the Contractholder  hereby agree, by signing below, that the Contract is
hereby amended by deleting Section 6.1 and by substituting the following Section
6.1 in lieu thereof:

6.1  Mortality Risk and Expense Risk Charges;  Annual  Variable  Investment Plus
     Factors: AUL shall deduct a daily mortality risk charge and a daily expense
     risk charge equal to the daily  equivalent of an annual  combined charge of
     1.25%  against the  average  daily net assets of each  Investment  Account.
     These charges shall be reflected in the Net  Investment  Factor as provided
     in Section 5.4(c).

     AUL shall multiply  the  portions (as delineated in the table below) of the
     total month-end  Account  Value in the Variable Account of all Participants
     in the contract   by the  monthly  equivalent of the  corresponding  Annual
     Variable  Investment  Plus  Factors  appearing  in  the table below.  These
     products shall  be added  together,  and  the sum shall be  divided  by the
     total month-end  Account Value in the Variable  Account of all Participants
     in  the  contract.  This  percentage  shall be  multiplied by the month-end
     Account Value of each Participant in each Investment Account. The resulting
     amount  for  each  Investment  Account shall be added to the  Participant's
     Account Value for that Investment Account.

                  AMERICAN UNITED LIFE INSURANCE COMPANY (AUL)

            BANK ONE AS CUSTODIAN ON BEHALF OF ANY PERSON ELIGIBLE TO

          BECOMES A PARTICIPANT UNDER THIS CONTRACT AND SUCH SUCCESSOR
              CUSTODIAN AS MAY BE APPOINTED FROM TIME TO TIME (THE
                                CONTRACTHOLDER)

                           EFFECTIVE DATE: MAY 1, 1993

AUL and the Contractholder  hereby agree, by signing below, that the Contract is
hereby  amended by deleting the  corresponding  Sections and  Subsections of the
Contract,  if any, and by inserting the following  Sections and  Subsections  in
lieu thereof:

1.12 "Fixed Interest  Account" means that fund of AUL's general asset account in
     which all or a portion  of a  Participant's  Account  Value may be held for
     accumulation at the Current Rates of Interest.

     (a)  Contributions  allocated,  or amounts transferred (excluding transfers
          discussed  in (c)  below),  to the  Fixed  Interest  Account  shall be
          credited to the open  interest  pocket and shall earn  interest at the
          Current  Rate of Interest  in effect for that  interest  pocket.  Such
          Contributions or transferred amounts, during the time that the Current
          Rate of Interest  exceeds the Guaranteed Rate of Interest,  shall earn
          interest at such  credited  Current  Rate of  Interest  for at least 1
          year. After such 1-year period, AUL reserves the right to declare,  at
          any time,  a new Current  Rate of Interest to be applied to funds held
          within that  interest  pocket.  Any such new Current  Rate of Interest
          must remain in effect for that interest pocket for at least 1 year.

     (b)  If AUL changes the Current Rate of Interest for such new Contributions
          or new amounts transferred to the Fixed Interest Account, the previous
          open  interest  pocket  shall  close,  and any such  Contributions  or
          amounts  transferred  on or after the  effective  date of such  change
          shall be  credited  to a new  open  interest  pocket  and  shall  earn
          interest  at the new  Current  Rate of Interest in effect for such new
          open  interest  pocket.  Therefore,  at any given time,  various funds
          credited to a Participant  Account and allocated to the Fixed Interest
          Account may be earning interest at different Current Rates of Interest
          for different periods of time.

     (c)  Any contribution to another AUL P-12833 contract which is allocated to
          the Fixed  Interest  Account and which is transferred to this contract
          (plus gains and minus losses thereon) and allocated

P-12833.OT.AMD
<PAGE>

          to the Fixed  Interest  Account,  beginning  with  the  date  of  such
          transfer, shall  be credited  with  the Current Rate of Interest under
          this  contract  which  was  in  effect  on  the  date  the transferred
          contribution was originally deposited into the Fixed Interest  Account
          under the previous AUL contract.

1.15 "Investment  Account"  means each  subaccount of the Variable  Account made
     available to the  Contractholder by AUL and identified in Schedule A of the
     contract.  Schedule  A of the  contract  may be amended by AUL from time to
     time as  described  in Section 3.3.  Amounts  allocated  to any  Investment
     Account  identified in Schedule A of the contract  shall be invested in the
     shares of the  corresponding  Mutual Fund  Portfolio  listed in the current
     prospectus for the Variable Account.

1.17 "Mutual  Fund" means the AUL  American  Series Fund,  Inc., a  diversified,
     open-end management  investment  company  registered  under  The Investment
     Company  Act of l940,  and any other such  open-end  management  investment
     company made available by AUL.

1.20 "Portfolio" means a series of a particular Mutual Fund as described in that
     prospectus  for that  Mutual  Fund,  as such  prospectus  may be amended or
     supplemented from time to time.

1.24 "Withdrawal  Charge"  means a charge taken by AUL equal to a percentage  of
     the Account Value of a Participant  Account  withdrawn  pursuant to Section
     4.8, where the percentage  varies by the number of full years measured from
     the  date  that  Participant  Account  is  established,  or from the date a
     Participant  Account is established  under a previous AUL P-12833  contract
     from which amounts have been  transferred to this Participant  Account,  to
     the date  the  Withdrawal  Charge  is  determined.  Such  percentage  is as
     follows:

               During
            Account Years                    Percentage

                 1                               6
                 2                               5
                 3                               4
                 4                               3
                 5                               2
                 6                               1
           Thereafter                            0

In no event will the cumulative total of all Withdrawal Charges, including those
previously  assessed  against any amount  withdrawn from a Participant  Account,
exceed 9% of total Contributions allocated to that Participant Account.


3.1  Amount of Contributions:

     (a)  Contributions  may vary in amount and  frequency;  however,  a minimum
          Contribution  of at least  $100,000 must be made for a Participant  in
          order to establish a Participant Account. Any additional Contributions
          made  within the  12-month  period  beginning  on the date the initial
          Contribution  is credited  to that  Participant  Account  (hereinafter
          called

P-12833.OT.AMD.1
<PAGE>

          a  Certificate Year)  shall  also  be  credited  to  that  Participant
          Account.  Any initial Contribution made within a different Certificate
          Year shall  also  be  subject to the $100,000 minimum, and any Contri-
          butions made within that  Certificate  Year  shall be  allocated  to a
          separate  Participant  Account  and  shall  be evidenced by a separate
          certificate  issued  to  the Participant.  AUL may change the  minimum
          Contribution acceptable under this contract, but any such change shall
          apply only to individuals who become Participants on or after the date
          of the change.

3.3  Addition, Deletion, or Substitution of Investments:

     (a)  AUL reserves the right,  subject to compliance with applicable law, to
          make additions to, deletions from,  substitution  for, or combinations
          of,  the  securities  that are  held by the  Variable  Account  or any
          Investment  Account or that the  Variable  Account  or any  Investment
          Account may  purchase.  AUL reserves the right to eliminate the shares
          of any of the  eligible  Portfolios  and to  substitute  shares of, or
          interests  in,  another  Portfolio of  the AUL  American  Series Fund,
          Inc., of another open-end,  registered  investment  company,  or other
          investment vehicle, for shares already purchased or to be purchased in
          the future  under the  contract,  if the shares of any or all eligible
          Portfolios  are no longer  available for  investment,  or if, in AUL's
          judgment, further investment in any or all eligible Portfolios becomes
          inappropriate  in view of the purposes of the Variable  Account or the
          contract.  Where required under applicable law, AUL will no substitute
          any shares in the Variable  Account or any Investment  Account without
          notice, Participant approval,  or prior approval of the Securities and
          Exchange  Commission or a state  insurance  commissioner,  and without
          following  the filing or other  procedures  established by  applicable
          state insurance regulators. Nothing contained herein shall prevent the
          Variable  Account from purchasing other securities for other series or
          classes of contracts, or from effecting a conversion between series or
          classes of  contracts  on the basis of requests  made by a majority of
          participants or as permitted by federal law.

     (b)  AUL reserves the right to establish  additional  Investment  Accounts,
          each of which would invest in the corresponding  Mutual Fund Portfolio
          listed in the current prospectus for the Variable Account, or in other
          securities or investment vehicles. AUL reserves the right to eliminate
          or combine  existing  Investment  Accounts if, in its sole discretion,
          marketing, tax, or investment conditions so warrant. AUL also reserves
          the right to provide other  Investment  Options under this contract at
          any time. Subject to any required regulatory  approvals,  AUL reserves
          the right to transfer  assets from any  Investment  Account to another
          separate account of AUL or Investment Account.

     (c)  In the  event  of  any  such  substitution  or  change,  AUL  may,  by
          appropriate  amendment,  make such changes in this  contract as may be
          necessary or appropriate to reflect such  substitution  or change.  If
          deemed  by AUL to be in the best  interests  of  persons  or  entities
          having voting rights under this contract,  the Variable Account may be
          operated  as a  management  investment  company  under The  Investment
          Company  Act of 1940 or any other  form  permitted  by law,  it may be
          deregistered  in the event  such  registration  is no longer  required
          under The  Investment  Company Act of 1940, or it may be combined with
          other separate accounts of AUL or an affiliate  thereof.  AUL may take
          such action as is necessary to comply with,  or to obtain,  exemptions
          from  the  Securities  and  Exchange  Commission  with  regard  to the
          Variable Account.  Subject to compliance with applicable law, AUL also
          may  combine  one or more  Investment  Accounts  and may  establish  a
          committee,  board, or other group to manage one or more aspects of the
          operation of the Variable Account.

3.5  Limitations on Transfers:

     (e)  Where a  Participant  has  outstanding  loans under this  contract,  a
          transfer from the Fixed Interest Account to the Variable Account shall
          be permitted only to the extent that the remaining Withdrawal Value of
          the  Participant  Account held in the Fixed  Interest  Account  equals
          twice the total of the  Participant's  outstanding  loans  under  that
          Participant Account.

4.8  Withdrawal Benefits:

     (a)(6) Effective  January 1, 1993, if, as provided in Internal Revenue Code
          Regulation Section  1.403(b)-2T Q&A-2, the distributee of any eligible
          rollover distribution elects to have the distribution paid directly to
          an eligible  retirement plan (as defined in Q&A-1 of that Section) and
          specifies the eligible retirement plan to which the distribution is to
          be  paid,  then  the  distribution  shall  be paid  to  that  eligible
          retirement plan in a direct rollover
     (d)  The  Account  Value to be applied  pursuant to this  Section  shall be
          determined  as of the  applicable  Valuation  Date  determined  in (c)
          above.  If the  entire  Account  Value  of a  Participant  Account  is
          withdrawn,  the Participant shall be paid the Withdrawal Value. If the
          Participant  requests that a specified  percentage or dollar amount be
          paid to the  Participant,  AUL  shall  withdraw  from the  Participant
          Account an amount equal to the dollar amount to be paid divided by the
          difference  between 1 and the  decimal  equivalent  of the  applicable
          Withdrawal Charge. Notwithstanding the previous sentence, in the first
          Contract Year in which a Participant  Account is  established,  and in
          the next  succeeding  Contract Year, the Participant may withdraw from
          that Participant  Account up to 10% of the sum of the Account Value of
          that  Participant   Account,   determined  as  of  the  last  Contract
          Anniversary   preceding   the   request  for  the   withdrawal,   plus
          Contributions  made  during  the  applicable  Contract  Year,  without
          application of any Withdrawal Charge. In any subsequent Contract Year,
          the Participant may withdraw from that  Participant  Account up to 10%
          of the Account Value of that Participant Account, determined as of the
          last Contract  Anniversary  preceding the request for the  withdrawal,
          without application of any Withdrawal Charge.  Where amounts have been
          transferred  to this  contract  from  another  AUL  P-12833  contract,
          Contract  Years of  participation  for  purposes of this 10%  free-out
          provision  shall be determined by using the date of the  Participant's
          first contribution to the Participant Account in the previous contract
          which was transferred. Also, where a Participant has outstanding loans
          under this contract,  a partial  withdrawal by a Participant  from the
          Fixed Interest  Account shall be permitted only to the extent that the
          remaining  Withdrawal  Value of the  Participant  Account  held in the
          Fixed  Interest  Account  equals twice the total of the  Participant's
          outstanding loans under that Participant Account.

4.9  Loans from the Fixed Interest Account:

     (a)  A  Participant  who has all or a  portion  of the  Account  Value of a
          Participant  Account  held in the Fixed  Interest  Account  may borrow
          money from AUL,  using such Account  Value held in the Fixed  Interest
          Account as the only  security  for the loan,  by  submitting  a proper
          written  request to AUL at its Home Office.  The minimum amount of any
          single loan is $2,000.  The maximum amount that may be borrowed at any
          time is an amount  which,  when combined with the largest loan balance
          during the prior 12  months,  does not exceed the lesser of (l) 50% of
          the  Withdrawal  Value of the  Participant  Account  held in the Fixed
          Interest  Account,  or  (2)  $50,000.  The  Withdrawal  Value  of  the
          Participant Account held in the Fixed Interest Account,  which must be
          at least twice the amount of the outstanding loan balance, shall serve
          as security for the loan, and shall continue to earn interest. Payment
          by AUL of the loan amount may be delayed for up to 6 months.

     (d)  If a loan either  remains unpaid at the end of its term, or if, at any
          time, l02% of the total of all the Participant's loan balances under a
          Participant  Account equals the Withdrawal  Value of that  Participant
          Account allocated to the Fixed Interest Account, then AUL shall deduct
          these balances plus an expense  charge equal to 2% of the  outstanding
          loan  balances  from the  Participant  Account's  share  of the  Fixed
          Interest  Account.  If  a  Participant  has  outstanding  loans,  then
          withdrawals  or transfers to the Variable  Account  shall be permitted
          only to the  extent  that the  Participant  Account's  remaining With-
          drawal Value in the Fixed  Interest  Account equals twice the total of
          any  outstanding  loans  of the  Participant  under  that  Participant
          Account. All loan balances plus the 2% expense charge shall be paid or
          satisfied  in full  before any amount from the  Participant  Account's
          share of the Fixed Interest Account is paid as a full withdrawal, as a
          death   benefit,   upon   annuitization,   or  as  another   permitted
          distribution.

5.1  Time of Valuation: All assets of each Portfolio shall be valued as provided
     in the prospectus for the applicable  Mutual Fund as such prospectus may be
     amended or supplemented from time to time.

5.3  Value of Accumulation  Units: The value of an Accumulation  Unit in the AUL
     American Equity,  Bond, Money Market, and Managed  Investment  Accounts was
     established  at $1.00 as of April 12,  1990.  The value of an  Accumulation
     Unit in any other  Investment  Account avail able under this contract shall
     be  established  at  $1.00  as of the  date of the  first  deposit  to such
     Investment  Account.  The value of an Accumulation  Unit in each Investment
     Account as of any Valuation Period  thereafter is equal to the dollar value
     of one Accumulation  Unit in that Investment  Account as of the immediately
     preceding  Valuation  Period  multiplied by the Net Investment  Factor,  as
     defined  in  Section  5.4,  for that  Investment  Account  for the  current
     Valuation  Period.  The value of an  Accumulation  Unit for each Investment
     Account shall be deter mined for each Valuation Period before giving effect
     to any additions, withdrawals, or transfers. After such  determination, the
     additions,  withdrawals,  or transfers  which are  effective as of that day
     shall then be made.

P-12833.OT.AMD.3
<PAGE>

5.4  Determining the Net Investment  Factor:  The Net Investment Factor for each
     Investment  Account for any Valuation  Period is determined by dividing (a)
     by (b), and then subtracting (c) from that result, where:

     (a)  is equal to:

          (1)  the net asset value of a Portfolio  share held in the  Investment
               Account determined as of the end of the current Valuation Period,
               plus

          (2)  the per share  amount of any dividend or other  distribution,  if
               any, paid by the Portfolio during the current  Valuation  Period,
               plus or minus

          (3)  any credit or charge for any taxes  paid or  reserved  for by AUL
               during the current  Valuation  Period which are determined by AUL
               to be attributable to operation of the Investment Account;

     (b)  is the net asset  value of a  Portfolio  share held in the  Investment
          Account  deter  mined  as of  the  end of  the  immediately  preceding
          Valuation Period; and

     (c)  is a daily  charge  factor  determined  by AUL to reflect  the charges
          assessed  against the assets of the  Investment  Account for mortality
          and expense risks, as authorized by Section 6.1.

6.1  Mortality Risk and Expense Risk Charges: AUL shall deduct a daily mortality
     risk charge and a daily  expense risk charge equal to the daily  equivalent
     of an annual  combined charge of 1.25% against the average daily net assets
     of each  Investment  Account.  These  charges shall be reflected in the Net
     Investment Factor as provided in Section 5.4(c).



6.2  Investment  Management  Charge:  A Mutual  Fund  shall  pay any  investment
     advisory fee and certain other expenses,  which may include its operational
     and  organizational  expenses,  as described  in the current prospectus for
     that  Mutual Fund as it may be amended or  supplemented  from time to time.
     These  expenses  may vary  from year to year.  The net asset  value of each
     Portfolio  reflects such  investment  advisory fee and other expenses which
     are deducted from the assets of such Portfolio.

6.3  Administrative  Charge:  AUL shall  deduct  an  administrative  charge  per
     Contract  Quarter equal to the lesser of $0.00 or 0.5% of the Account Value
     on the last day of each Contract Quarter from each  Participant  Account in
     existence on such day for as long as the  Participant  Account is in effect
     during the  Accumulation  Period.  This charge is to be prorated among each
     subaccount of the Participant  Account which corresponds to each Investment
     Option  utilized under this contract by that  Participant  Account.  If the
     entire balance of a Participant  Account is applied or withdrawn before the
     last day of the Contract Quarter pursuant to Sections 4.1, 4.7, or 4.8, the
     administrative  charge attributable to the period of time which has elapsed
     since the first day of the Contract  Quarter in which such  application  or
     withdrawal of funds is made shall not be deducted  from the amount  applied
     or withdrawn.

6.6  Reduction or Waiver of Certain Charges:  AUL may reduce or waive the amount
     of the Withdrawal Charge  or the administrative charge discussed in Section
     6.3 where the  expenses  associated  with the sale of this  contract or the
     administrative  costs  associated with this contract are reduced,  or where
     this  contract is sold to the  directors  or employees of AUL or any of its
     affiliates,  or to directors or any  employees of the AUL American  Series
     Fund, Inc. or any other Mutual Fund made available by AUL.

8.15 Voting:

     (a)  AUL is the  legal  owner of the  shares  of a Mutual  Fund held by the
          Investment Accounts of the Variable Account. AUL shall exercise voting
          rights  attributable  to the  shares  of  each  Portfolio  held in the
          Investment  Accounts  at  any  regular  and  special  meetings  of the
          shareholders of a Mutual Fund on matters requiring  shareholder voting
          under The Investment Company Act of l940 or other applicable laws. AUL
          shall exercise  these  voting  rights based on  instructions  received
          from persons having the voting  interest in  corresponding  Investment
          Accounts of the Variable Account.  However,  if The Investment Company
          Act of l940 or any  regulations  thereunder  should be amended, or  if
          the present  interpretation thereof should change, and as a result AUL
          deter mines that it is  permitted  to vote the shares of a Mutual Fund
          in its own right,  it may elect to do so. AUL will vote  shares of any
          Investment  Account,  if any,  that it  owns  beneficially  in its own
          discretion,  except  that if a Mutual  Fund  offers  its shares to any
          insurance  company separate account that funds variable life insurance
          contracts or if otherwise  required by  applicable  law, AUL will vote
          its own shares in the same proportion  as the voting instructions that
          are received in a timely manner for contracts and Participant Accounts
          participating in the Investment Account.

     (b)  The persons  having the voting  interest  under this  contract are the
          Participants.  Unless otherwise required by applicable law, the number
          of Mutual Fund shares of a  particular  Portfolio  as to which  voting
          instructions  may be given to AUL is determined by dividing  the value
          of all of  the  Accumulation  Units  of the  corresponding  Investment
          Account  attributable to this contract on a particular date by the net
          asset  value  per  share  of  that  Portfolio  as of  the  same  date.
          Fractional  votes  will be  counted.  The  number of votes as to which
          voting  instructions  may be given will be  determined  as of the date
          coincident with  the date  established by the  applicable  Mutual Fund
          for determining  shareholders eligible  to vote at the meeting of that
          Mutual Fund. If required by the  Securities  and Exchange  Commission,
          AUL reserves the right to determine in a different  fashion the voting
          rights attributable to the shares of a Mutual Fund.

     (c)  Voting rights attributable to this contract for which no timely voting
          instructions  are received will be voted by AUL in the same proportion
          as the voting  instructions  which are received in a timely manner for
          all  contracts  and  Participant   Accounts   participating   in  that
          Investment Account.

     (d)  Neither the  Variable  Account nor AUL is under any duty to inquire as
          to the instructions  received  or  the  authority of  Contractholders,
          Participants, or others to instruct the voting of Mutual Fund shares.

     (e)  Every person or entity  having such voting  rights shall  receive such
          reports or prospectuses  concerning  the Variable  Account or a Mutual
          Fund as may be required by applicable federal law.

ACCUMULATION  UNITS IN ANY  INVESTMENT  ACCOUNT  FOR WHICH THIS  CONTRACT  MAKES
PROVISION MAY INCREASE OR DECREASE IN DOLLAR VALUE  ACCORDING TO THE  INVESTMENT
PERFORMANCE OF THE UNDERLYING ASSETS IN THE CORRESPONDING  MUTUAL FUND OR MUTUAL
FUND PORTFOLIO IN WHICH THE INVESTMENT ACCOUNT INVESTS. THE VALUE OF SUCH ASSETS

By deleting the  corresponding  Sections or  Subsections  of the Contract and by
substituting  the following  Sections or  Subsections  in lieu  thereof,  and by
making  any  required  corresponding  changes  in the Table of  Contents  of the
Contract:

1.6  "Contract  Anniversary" means the first day of the second Contract Year and
     each subsequent  Contract Year. Each Contract  Anniversary  after the First
     Contract Anniversary shall be the same day of the same month as the day and
     month  which is  stated  on the face  page of this  contract  for the First
     Contract Anniversary.

1.9  "Contributions"  means  amounts  paid to AUL from  time to time  by,  or on

1.15 "Investment Account" means each subaccount of the Variable Account which is
     maintained  by AUL and  made  available  to the  Contractholder  by AUL and
     identified in Schedule A of the contract. Schedule A of the contract may be
     amended  by AUL from time to time as  described  in  Section  3.3.  Amounts
     allocated  to  any  Investment  Account  identified  in  Schedule  A of the

     of such date. Each  Participant  Account Year thereafter  begins on such an
     anniversary  date  and  ends  on the day  immediately  preceding  the  next
     succeeding  anniversary  date.  The  Withdrawal  Charge  percentage  is  as
     follows:

                 During                               Withdrawal Charge
        Participant Account Years                        Percentage

                   1-5                                       8%
                   6-10                                      4%
                Thereafter                                   0%

     In no event will the cumulative total of all Withdrawal Charges,  including
     those  previously  assessed against any amount withdrawn from a Participant
     Account,  exceed 9% of total  Contributions  allocated to that  Participant
     Account.

3.1  Amount of Contributions:

     (a)  Contributions  may vary in amount and frequency;  however,  when made,
          they must be at least equal to a minimum annual  Contribution  of $200
          per  Participant in any full Contract Year. AUL may change the minimum
          annual  Contribution  acceptable  under  this  contract,  but any such
          change shall apply only to individuals  who become  Participants on or
          after the date of the change.

3.2  How Contributions Are Handled:

     (b)  (1)  The initial  Contribution  for  a  Participant  shall be credited
               and allocated to the Participant  Account no later than the close
               of business on the second  business day of AUL after the later of
               (1) the business  day that AUL receives the initial  Contribution
               at its Home Office, or (2) the business day that AUL receives, at
               its Home Office,  the data required to establish the  Participant
               Account,   instructions  regarding  the  amount  of  the  initial
               Contribution for the Participant,  and Investment Option election
               instructions regarding the initial Contribution.

          (2)  If the data  required  to  establish  a  Participant  Account and
               instructions  regarding  the  amount  of a  Contribution  for the
               Participant  are not received by AUL at its Home Office  within 5
               business  days after AUL first  receives that  Contribution,  AUL
               shall return that  Contribution to the contributing  party unless
               the   contributing   party   consents  to  AUL   retaining   that
               Contribution  until the earlier of (i) the date AUL receives such
               data and instructions and, therefore,  can properly allocate that
               Contribution to the Participant  Account or (ii) 25 days from the
               date that Contribution is received by AUL.

P-12833.AMD.2
<PAGE>


          (3)  If  the  data  required  to  establish  a  Participant   Account,
               including  any  annuity  enrollment  form  required  by AUL,  and
               instructions  regarding  the  amount  of a  Contribution  for the
               Participant are received,  but an Investment  Option election for
               that Participant is not received, by AUL at its Home Office as of
               the date AUL receives that Contribution,  AUL shall allocate that
               Contribution to the Investment Option election  identified in the
               Participant's annuity enrollment form, which is generally the AUL
               American Money Market  Investment  Account.  If AUL  subsequently
               receives the data required to establish the Participant  Account,
               instructions  regarding  the amount of the  Contribution  for the
               Participant,  and an Investment  Option election,  AUL shall then
               transfer such amounts  credited to the AUL American  Money Market
               Investment  Account or other Investment  Option identified in the
               Participant's annuity enrollment form, plus gains or minus losses
               thereon,  to  another  Investment  Option,  if such  election  so
               directs.

     (c)  Contributions for a Participant subsequent to the initial Contribution
          shall be credited and allocated to the  Participant  Account as of the
          close of  business on the later of (1) the  Valuation  Period in which
          AUL receives that Contribution at its Home Office or (2) the Valuation
          Period in which AUL receives, at its Home Office, the data required to
          establish the Participant Account,  instructions  regarding the amount
          of  that  Contribution  for the  Participant,  and  Investment  Option
          election instructions.

     (d)  Within any one  Participant  Account,  the amount so credited shall be
          allocated  to an  Investment  Option  in  increments  elected  by  the
          Participant in a form  acceptable to AUL. If no investment  allocation
          instruction is made with respect to any Participant Account, AUL shall
          process  such credits in  accordance  with the  investment  allocation
          instruction applicable to the immediately preceding Contribution.  The
          Participant  may  change an  investment  allocation  instruction  with
          respect to future allocations to the applicable Participant Account by
          giving  new  investment  allocation  instructions  to AUL at its  Home
          Office in a form acceptable to AUL.

3.3  Addition, Deletion, or Substitution of Investments:

     (a)  AUL reserves the right,  subject to compliance with applicable law, to
          make additions to, deletions from,  substitution  for, or combinations
          of,  the  securities  that are  held by the  Variable  Account  or any
          Investment  Account or that the  Variable  Account  or any  Investment
          Account may  purchase.  AUL reserves the right to eliminate the shares
          of any of the eligible  Mutual Funds or Mutual Fund  Portfolios and to
          substitute  shares of, or interests in,  another  Portfolio of the AUL
          American Series Fund, Inc.,  another open-end,  registered  investment
          company, or another investment  vehicle,  for shares already purchased
          or to be purchased in the future under the contract,  if the shares of
          any or all  eligible  Mutual  Funds or Mutual Fund  Portfolios  are no
          longer  available for investment,  or if further  investment in any or
          all  eligible   Mutual  Funds  or  Mutual  Fund   Portfolios   becomes
          inappropriate  in view of the purposes of the Variable  Account or the
          contract. Where required under applicable law, AUL will not substitute
          any shares in the Variable  Account or any Investment  Account without
          notice,  Participant approval, or prior approval of the Securities and
          Exchange  Commission or a state  insurance  commissioner,  and without
          following  the filing or other  procedures  established  by applicable
          state insurance regulators. Nothing contained herein shall prevent the
          Variable  Account from purchasing other securities for other series or
          classes of contracts, or from effecting a

P-12833.AMD.3
<PAGE>

          conversion  between  series  or  classes  of contracts on the basis of
          requests made by a majority of participants or as permitted by federal
          law.

     (b)  AUL reserves the right to establish  additional  Investment  Accounts,
          each of which would invest in the corresponding  Mutual Fund or Mutual
          Fund  Portfolio  listed in the  current  prospectus  for the  Variable
          Account, or in other securities or investment vehicles.  AUL re serves
          the right to  eliminate  or combine  existing  Investment  Accounts if
          marketing, tax, or investment conditions so warrant. AUL also reserves
          the right to provide other  Investment  Options under this contract at
          any time. Subject to any required regulatory  approvals,  AUL reserves
          the right to transfer  assets from any  Investment  Account to another
          separate account of AUL or Investment Account.

     (c)  In the  event  of  any  such  substitution  or  change,  AUL  may,  by
          appropriate  amendment,  make such changes in this  contract as may be
          necessary or appropriate to reflect such  substitution  or change.  If
          deemed  by AUL to be in the best  interests  of  persons  or  entities
          having voting rights under this contract,  the Variable Account may be
          operated  as a  management  investment  company  under The  Investment
          Company  Act of 1940 or any other  form  permitted  by law,  it may be
          deregistered  in the event  such  registration  is no longer  required
          under The  Investment  Company Act of 1940, or it may be combined with
          other separate accounts of AUL or an affiliate  thereof.  AUL may take
          such action as is necessary to comply with,  or to obtain,  exemptions
          from  the  Securities  and  Exchange  Commission  with  regard  to the
          Variable Account.  Subject to compliance with applicable law, AUL also
          may  combine  one or more  Investment  Accounts  and may  establish  a
          committee,  board, or other group to manage one or more aspects of the
          operation of the Variable Account.

3.4  Transfers:

     (a)  Subject to the  limitations of Section 3.5, the Participant may direct
          AUL, in a form acceptable to AUL, to transfer the amounts  credited to
          an  Investment  Option  to any  other  Investment  Option  during  the
          Accumulation  Period. Any transfer from an Investment Account shall be
          effective as of the close of business on the  Valuation  Date that AUL
          receives the Participant's direction.

3.5  Limitations on Transfers:

     (a)  The  minimum  transfer  from the  Participant  Account's  share of any
          Investment  Option is the lesser of $500 or the Participant  Account's
          entire share of that  Investment  Option.  However,  if that  transfer
          reduces the Participant  Account's  remaining share of that Investment
          Option to less than $500,  the entire  remaining  share  shall also be
          transferred.

     (b)  Amounts  transferred  from the Fixed  Interest  Account on behalf of a
          Participant  during  any  Contract  Year  shall not  exceed 20% of the
          Participant  Account's share of the Fixed Interest Account  determined
          as of the  later  of the  Contract  Date or the  Contract  Anniversary
          immediately  preceding the request for transfer.  Notwithstanding  the
          previous  sentence,  if the  Participant  Account's share of the Fixed
          Interest Account is less than $2,500 determined as of the later of the
          Contract Date or the Contract  Anniversary  immediately  preceding the
          request for transfer, the amount transferrable from the Fixed Interest
          Account  for  that  Contract  Year  is  the  lesser  of  $500  or  the
          Participant  Account's entire share of the Fixed Interest Account. And
          if that transfer reduces the Participant
<PAGE>


          Account's remaining  share of the Fixed Interest  Account to less than
          $500, the entire remaining share shall also be transferred.

4.5  Minimum  Payments:  If the total  Account  Value is less than $2,000,  such
     value  (subject to Section 6.5 and minus any  outstanding  loan balances of
     the Participant and any unpaid expense charges on such loans) shall be paid
     in a lump sum to the  annuitant  rather than  annuitized  under the annuity
     options  provided in Section 4.2.  Additionally,  if the  proposed  monthly
     annuity  payment  should fall below  AUL's  periodically  adjusted  minimum
     monthly annuity payment,  AUL reserves the right to make payments on a less
     frequent basis (i.e.,  quarterly,  semiannually,  or annually), so that the
     actual annuity payment is equal to or greater than the established  minimum
     level,  or to pay the Account  Value  (subject to Section 6.5 and minus any
     outstanding loan balances of the Participant and any unpaid expense charges
     on such loans) in a single sum.

4.7  Death Benefits:

     (a)  Upon   receipt  of  written   instructions   from  the   Participant's
          beneficiary  (or, if  applicable,  the  secondary  beneficiary  of the
          Participant)  and  of  due  proof  of  the   Participant's   (and,  if
          applicable, the beneficiary's) death during the Accumulation Period at
          its Home Office, AUL shall apply the Account Value (subject to Section
          6.5, and minus the  Participant's  outstanding  loan balance,  if any,
          under this contract and any unpaid expense  charges due on such loans)
          of the  Participant  Account  for the  purpose  of  providing  a death
          benefit.  The  death  benefit  shall be paid to the  beneficiary  last
          properly  designated  in  writing  to AUL at its  Home  Office  by the
          Participant,  or, if there is no designated  beneficiary living on the
          date of the  Participant's  death, to the  Participant's  estate.  The
          Participant's  beneficiary  may also designate a  beneficiary.  If any
          beneficiary  dies  while  receiving  payments  and no  beneficiary  is
          designated to receive any remaining payments,  such remaining payments
          shall be made to the deceased beneficiary's estate.

     (b)  The  Account  Value  to be  applied  pursuant  to (a)  above  shall be
          determined as of the close of business on the Valuation  Date that AUL
          receives  a proper  withdrawal  request  (or due  proof of  death,  if
          received later), in a form acceptable to AUL, at its Home Office.

     (c)  (1)  The  benefit  shall  be  payable  in  accordance  with one of the
               following  provisions  as  elected  by  the  Participant  or  the
               beneficiary if the Participant did not make an election:

               (i)  The entire  Account Value to be applied shall be paid to the
                    beneficiary  in a single sum or other method not provided in
                    (ii) below on or before  December  31 of the  calendar  year
                    which  contains  the  fifth  anniversary  of the date of the
                    Participant's death; or

               (ii) The benefit shall be paid as an annuity in  accordance  with
                    the Annuity  Options  shown in Section 4.2 over a period not
                    to exceed the life or life expectancy of the beneficiary. If
                    the beneficiary is not the  Participant's  surviving spouse,
                    the  annuity  must  begin on or  before  December  31 of the
                    calendar  year  immediately  following  the calendar year in
                    which  the  Participant  died.  If  the  beneficiary  is the
                    Participant's  surviving spouse,  the annuity need not begin
                    before  December  31 of  the  calendar  year  in  which  the
                    Participant would have attained age 70 1/2.
<PAGE>

          (2)  If a Participant dies on or after his Annuity  Commencement Date,
               any interest remaining under the Annuity Option selected shall be
               paid at least as rapidly as prior to the Participant's death.

          (3)  If  payment  is to be made in a cash lump sum,  payment  shall be
               made within 7 days of the date of valuation,  as determined above
               in this  Section,  except as AUL may be  permitted  to defer such
               payment  of  amounts   derived  from  the  Variable   Account  in
               accordance with the provisions of federal  securities laws. Also,
               AUL reserves the right to defer the payment of amounts  withdrawn
               from the Fixed  Interest  Account  for a period of up to 6 months
               after AUL receives proper instructions at its Home Office.

4.8  Withdrawal  Benefits: A Participant may direct AUL at its Home Office, in a
     form  acceptable  to AUL,  to withdraw  all or a portion of the  Withdrawal
     Value of his Participant Account, subject to the following provisions:

     (a)  Amounts  attributable  to amounts  held as of December  31, 1988 under
          another Code Section 403(b) annuity contract may be withdrawn.

     (b)  Amounts  attributable to  Contributions  made other than pursuant to a
          salary  reduction  agreement  (within  the  meaning  of  Code  Section
          402(g)(3)(C)) may be withdrawn.

     (c)  Amounts  attributable  to  Contributions  made  pursuant  to a  salary
          reduction agreement (within the meaning of Code Section  402(g)(3)(C))
          may be withdrawn, provided that any distribution of such amounts shall
          not occur  until  the  Participant  has  either  attained  age 59 1/2,
          separated  from service,  become  totally  disabled (as defined by the
          Internal  Revenue  Service),  or experienced a hardship (as defined by
          the  Internal  Revenue  Service).  However,  in the case of a hardship
          withdrawal,  any  gain  credited  to  such  Contributions  may  not be
          withdrawn.

     (d)  Withdrawal  of any  amount  from this  contract  which is  transferred
          directly  by AUL  pursuant  to  Participant  instructions  to  another
          tax-deferred annuity funding vehicle under applicable Internal Revenue
          Service rules and  regulations  shall be subject to application of the
          Withdrawal Charge.

     (e)  If,  as  provided  in  Internal   Revenue  Code   Regulation   Section
          1.403(b)-2T   Q&A-2,   the   distributee  of  any  eligible   rollover
          distribution  elects  to have the  distribution  paid  directly  to an
          eligible  retirement  plan (as defined in Q&A-1 of that  Section)  and
          specifies the eligible retirement plan to which the distribution is to
          be  paid,  then  the  distribution  shall  be paid  to  that  eligible
          retirement plan in a direct rollover.

     (f)  AUL  shall  not  be  responsible   for   determining  a  Participant's
          compliance with the requirements  above. Any withdrawal  request shall
          include  certification  as to  the  purpose  of  the  withdrawal.  The
          Participant  assumes full  responsibility for determining  whether the
          withdrawal is permitted under applicable law. AUL may rely solely upon
          the representations of the Participant made in the withdrawal request.

     (g)  Withdrawals  from a  Participant  Account's  share  of any  Investment
          Option may not be made in an amount  less than the  smaller of $500 or
          the Participant Account's entire share

<PAGE>

          of the  Investment Option.  If a withdrawal  reduces  the  Participant
          Account's  share of an  Investment  Option  to less  than  $500,  such
          remaining share shall also be withdrawn (except for amounts prohibited
          from being distributed because Subsection (c) above is not met).

     (h)  A withdrawal  request shall be effective,  and the Account Value to be
          applied pursuant to this Section shall be determined,  as of the close
          of  business  on  the  Valuation  Date  that  AUL  receives  a  proper
          withdrawal  request,  in a form acceptable to AUL, at its Home Office.
          If  it  is  necessary  to  withdraw  the  entire  Account  Value  of a
          Participant Account to make a lump- sum cash payment,  the amount paid
          shall equal the Withdrawal Value, minus any Section 6.5 charges. If it
          is not  necessary  to withdraw the entire  Account  Value to make such
          payment, AUL shall reduce the Account Value of the Participant Account
          by an amount  sufficient  to make the cash  payment  requested  and to
          cover  the   Withdrawal   Charge   and  any   Section   6.5   charges.
          Notwithstanding  the previous sentence,  in the first Contract Year in
          which a  Participant  Account  is  established,  the  Participant  may
          withdraw  from that  Participant  Account  up to 10% of the sum of the
          Account Value of that Participant  Account (determined as of the later
          of the Contract Date or the Contract Anniversary immediately preceding
          the request for the withdrawal)  plus  Contributions  made during that
          Contract Year,  without  application of the Withdrawal  Charge. In the
          next succeeding  Contract Year, the Participant may also withdraw from
          that Participant  Account up to 10% of the sum of the Account Value of
          that Participant  Account  (determined as of the Contract  Anniversary
          immediately   preceding   the   request  for  the   withdrawal)   plus
          Contributions made during that Contract Year,  without  application of
          the  Withdrawal   Charge.   In  any  subsequent   Contract  Year,  the
          Participant  may withdraw from that  Participant  Account up to 10% of
          the Account Value of that  Participant  Account  (determined as of the
          Contract  Anniversary   immediately  preceding  the  request  for  the
          withdrawal) without application of the Withdrawal Charge.  Also, where
          a Participant  has  outstanding  loans under this contract,  a partial
          withdrawal by a Participant  from the Fixed Interest  Account shall be
          permitted  only to the extent that the remaining  Withdrawal  Value of
          the  Participant  Account held in the Fixed  Interest  Account  equals
          twice the total of the  Participant's  outstanding  loans  under  this
          contract.

     (i)  AUL shall pay any cash lump sum to the Participant  within 7 days from
          the appropriate  Valuation Date as determined in Subsection (h) above,
          except  as AUL may be  permitted  to defer  such  payment  of  amounts
          withdrawn  from the Variable  Account in accordance  with  appropriate
          provisions of the federal  securities  laws. AUL reserves the right to
          defer the payment of amounts withdrawn from the Fixed Interest Account
          for a period  of up to 6 months  after  AUL  receives  the  withdrawal
          request at its Home Office.

     (j)  Withdrawals  from a Participant  Account's share of the Fixed Interest
          Account shall be made on a  first-in/first-out  basis so that all or a
          portion of the amounts credited to the Participant  Account's share of
          the Fixed  Interest  Account  (other than amounts which are prohibited
          from being distributed  because Subsection (c) above is not met) which
          have been on deposit  for the longest  period of time,  as well as the
          interest credited thereon, shall be withdrawn first.

5.1  Valuation  of Mutual Fund or Mutual Fund  Portfolio  Assets:  All assets of
     each Mutual Fund or Mutual  Fund  Portfolio  shall be valued as provided in
     the prospectus  for the applicable  Mutual Fund or Mutual Fund Portfolio as
     such prospectus may be amended or supplemented from time to time.
<PAGE>

5.2  Accumulation  Units:  Any  amounts  that are  allocated  to any  Investment
     Account on behalf of a  Participant  shall be credited  to his  Participant
     Account in the form of Accumulation Units on the basis of the value of such
     units  in that  Investment  Account  as of the  later of (1) the end of the
     Valuation  Period on which such  amounts  are  received  by AUL at its Home
     Office or (2) the end of the Valuation Period on which the data required to
     establish  the  Participant  Account  and  allocate  such  amounts  to  the
     Participant  Account and to  Investment  Options are received by AUL at its
     Home Office.  However,  if the initial  Contribution  for a Participant  is
     allocated  pursuant to Section  3.2(b)(1) on the next succeeding  Valuation
     Period,  the unit  value as of the end of that  Valuation  Period  shall be
     used. Such crediting shall be made separately for amounts allocated to each
     Investment  Account.  The number of  Accumulation  Units in each Investment
     Account  credited to each  Participant  Account as of any Valuation  Period
     shall be  determined by dividing the amounts  allocated to that  Investment
     Account for that  Participant  Account as of such  Valuation  Period by the
     dollar value of one Accumulation Unit in that Investment  Account as of the
     close of  business  on the  applicable  Valuation  Period.  The  number  of
     Accumulation  Units thus determined  shall not be changed by any subsequent
     change in the dollar value of the Accumulation Units.

5.3  Value of Accumulation  Units: The value of an Accumulation  Unit in the AUL
     American Equity,  Bond, Money Market, and Managed  Investment  Accounts was
     established  at $1.00 as of April 12,  1990.  The value of an  Accumulation
     Unit in any other Investment Account available under this contract shall be
     established at $1.00 as of the date of the first deposit to such Investment
     Account. The value of an Accumulation Unit in each Investment Account as of
     any  Valuation  Period  thereafter  is  equal  to the  dollar  value of one
     Accumulation  Unit  in  that  Investment  Account  as  of  the  immediately
     preceding  Valuation  Period  multiplied by the Net Investment  Factor,  as
     defined  in  Section  5.4,  for that  Investment  Account  for the  current
     Valuation  Period.  The value of an  Accumulation  Unit for each Investment
     Account shall be determined for each Valuation  Period before giving effect
     to any additions,  withdrawals, or transfers. After such determination, the
     additions,  withdrawals,  or transfers  which are  effective as of that day
     shall then be made.

5.4  Determining the Net Investment  Factor:  The Net Investment Factor for each
     Investment  Account for any Valuation  Period is determined by dividing (a)
     by (b), and then subtracting (c) from that result, where:

     (a)  is equal to:

          (1)  the net asset  value of a Mutual  Fund or Mutual  Fund  Portfolio
               share held in the Investment  Account determined as of the end of
               the current Valuation Period, plus

          (2)  the per share  amount of any dividend or other  distribution,  if
               any, paid by the Mutual Fund or Mutual Fund Portfolio  during the
               current Valuation Period, plus or minus

          (3)  any credit or charge for any taxes  paid or  reserved  for by AUL
               during the current  Valuation  Period which are determined by AUL
               to be attributable to operation of the Investment Account;

     (b)  is the net asset value of a Mutual Fund or Mutual Fund Portfolio share
          held  in  the  Investment  Account  determined  as of  the  end of the
          immediately preceding Valuation Period; and
<PAGE>

     (c)  is a daily  charge  factor  determined  by AUL to reflect  the charges
          assessed  against the assets of the  Investment  Account for mortality
          and expense risks, as authorized by Section 6.1.

6.1  Mortality Risk and Expense Risk Charges: AUL shall deduct a daily mortality
     risk charge and a daily  expense risk charge equal to the daily  equivalent
     of an annual  combined charge of 1.25% against the average daily net assets
     of each  Investment  Account.  These  charges shall be reflected in the Net
     Investment Factor as provided in Section 5.4(c).

6.2  Mutual Fund or Mutual Fund Portfolio Expenses: A Mutual Fund or Mutual Fund
     Portfolio shall pay any investment advisory fee and certain other expenses,
     which may include its ordinary operational and organizational  expenses, or
     any extraordinary expenses, as described in the current prospectus for that
     Mutual Fund or Mutual Fund  Portfolio as it may be amended or  supplemented
     from time to time. These expenses may vary from year to year. The net asset
     value of each Mutual  Fund or Mutual Fund  Portfolio  share  reflects  such
     investment  advisory fee and other  expenses  which are  deducted  from the
     assets of such Mutual Fund or Mutual Fund Portfolio.

6.6  Reduction or Waiver of Certain Charges:  AUL may reduce or waive the amount
     of the Withdrawal Charge or the administrative  charge discussed in Section
     6.3 where the  expenses  associated  with the sale of this  contract or the
     administrative  costs  associated with this contract are reduced,  or where
     this  contract is sold to the  directors  or employees of AUL or any of its
     affiliates,  or to  directors or any  employees of the AUL American  Series
     Fund, Inc.

8.2  AUL's Annual Statement: No provision or condition of this contract shall be
     deemed to control, determine, or modify any annual statement of AUL made to
     any insurance department, contractholder, regulatory body, or other person,
     nor  shall  anything  in  such  annual  statement  be  deemed  to  control,
     determine,  or modify the valuation provided for in this contract,  nor the
     values determined, nor the market, book, or other value of any asset in any
     Investment Account or Mutual Fund or Mutual Fund Portfolio,  nor any of the
     other provisions and conditions of this contract.

8.8  Election,  Notice,  or Direction  Requirements:  Wherever in this  contract
     reference is made to the  Contractholder or Participant making a request or
     giving notice or direction,  such request,  notice, or direction must be in
     writing, or in a form otherwise acceptable to AUL, and must be submitted to
     and received by AUL at its Home Office before  becoming  effective,  unless
     the Contractholder or Participant is otherwise directed by AUL.

8.15 Voting:

     (a)  AUL is the legal  owner of the shares of a Mutual  Fund or Mutual Fund
          Portfolio held by the Investment Accounts of the Variable Account. AUL
          shall exercise voting rights attributable to the shares of each Mutual
          Fund or Mutual Fund Portfolio  held in the Investment  Accounts at any
          regular and special  meetings of the  shareholders of a Mutual Fund on
          matters requiring  shareholder voting under The Investment Company Act
          of l940 or other  applicable  laws.  AUL shall  exercise  these voting
          rights based on  instructions  received from persons having the voting
          interest in corresponding Investment Accounts of the Variable Account.
          However,  if The  Investment  Company  Act of l940 or any  regulations
          thereunder should be amended, or if the present interpretation thereof
          should change,  and as a result AUL determines that it is permitted to
          vote the shares of a Mutual Fund or Mutual Fund  Portfolio  in its own
          right,  it may elect to do so. AUL will vote shares of any  Investment
          Account,  if any,  that it owns  beneficially  in its own  discretion,
          except  that if a Mutual  Fund or Mutual  Fund  Portfolio  offers  its
          shares to any insurance  company  separate account that funds variable
          life insurance  contracts or if otherwise  required by applicable law,
          AUL will vote its own  shares  in the same  proportion  as the  voting
          instructions  that are received in a timely  manner for  contracts and
          Participant Accounts participating in the Investment Account.

     (b)  The persons  having the voting  interest  under this  contract are the
          Participants.  Unless otherwise required by applicable law, the number
          of Mutual  Fund or Mutual  Fund  Portfolio  shares as to which  voting
          instructions  may be given to AUL is  determined by dividing the value
          of all of  the  Accumulation  Units  of the  corresponding  Investment
          Account  attributable to this contract on a particular date by the net
          asset value per share of that Mutual Fund or Mutual Fund  Portfolio as
          of the same  date.  Fractional  votes will be  counted.  The number of
          votes as to which voting  instructions may be given will be determined
          as of the date coincident with the date  established by the applicable
          Mutual  Fund or Mutual Fund  Portfolio  for  determining  shareholders
          eligible to vote at the meeting of that  Mutual  Fund.  If required by
          the  Securities  and  Exchange  Commission,  AUL reserves the right to
          determine in a different fashion the voting rights attributable to the
          shares of a Mutual Fund or Mutual Fund Portfolio.

     (c)  Voting rights attributable to this contract for which no timely voting
          instructions  are received will be voted by AUL in the same proportion
          as the voting  instructions  which are received in a timely manner for
          all  contracts  and  Participant   Accounts   participating   in  that
          Investment Account.

     (d)  Neither the  Variable  Account nor AUL is under any duty to inquire as
          to the  instructions  received or the  authority  of  Contractholders,
          Participants,  or  others to  instruct  the  voting of Mutual  Fund or
          Mutual Fund Portfolio shares.

     (e)  Every person or entity  having such voting  rights shall  receive such
          reports or  prospectuses  concerning the Variable  Account or a Mutual
          Fund or Mutual Fund Portfolio as may be required by applicable federal
          law.

The Participant's Certificate is hereby amended as follows:

By deleting the term "death benefit"  wherever it appears in the Certificate and
by substituting "Death Benefit" in lieu thereof.

And by deleting the corresponding Sections or Subsections of the Certificate and
by substituting the following Sections or Subsections in lieu thereof:

"Death Benefit" means the greater of:

(a)  the  Participant's  Account  Value  as of the  date the  Death  Benefit  is
     calculated, or

          (a)  the  balance  of the  Participant  Account's  share of the  Fixed

               Account on that date.

     1.2  "Accumulation  Period" means the period of time commencing on the date
on which a  Participant's  initial  Contribution  is credited to the Participant
Account and terminating on the date when such Participant Account is closed.

of increases to,  decreases from, and  accumulations  in any Investment  Account
during the Accumulation Period.

     1.4 "Annuity Commencement Date" means the first day of any month upon which
an annuity begins under this contract.  However,  for any  Participant,  amounts
allocated  to the  Participant  Account  will be  distributed  or commence to be
distributed no later than the first day of April  following the calendar year in
which such Participant attains age 70 1/2.

     1.5 "Code" means the Internal Revenue Code of l986, as amended.

     1.6 "Contract  Anniversary" means the first day of each Contract Year. Each
Contract  Anniversary after the First Contract Anniversary shall be the same day
of the same month as the day and month  which is stated on the face page of this
contract for the First Contract Anniversary.

     1.7 "Contract Quarter" means each of the four successive intervals of three
months, the sum of which corresponds to a 12-month Contract Year.

     1.8 "Contract  Year" means,  for the first such year, the period  beginning
with the Contract  Date and ending on the day  immediately  preceding  the First
Contract  Anniversary,  and  for  each  succeeding  Contract  Year,  the  period
beginning  with  a  Contract  Anniversary  and  ending  on the  day  immediately
preceding the next succeeding Contract Anniversary.

     1.9 "Contributions" means amounts paid in cash to AUL from time to time by,
or on behalf  of,  Participants,  which are  credited  to  Participant  Accounts
hereunder.  The legal title to, and  ownership of, such amounts is vested solely
in the Participant. The contract is established for the exclusive benefit of the
Participant or his beneficiaries.

     1.10 "Current Rates of Interest"  means each of the annual  effective rates
of interest as determined  and declared by AUL from time to time and as credited
to each  interest  pocket  maintained  within the Fixed  Interest  Account.  The
Current  Rates  of  Interest  shall  always  be  equal  to or  greater  than the
Guaranteed Rate of Interest.

     1.12  "Fixed  Interest  Account"  means  that fund of AUL's  general  asset
account in which all or a portion of a  Participant's  Account Value may be held
for accumulation at the Current Rates of Interest.

          (a)  Contributions  allocated,  or amounts  transferred,  to the Fixed
               Interest  Account shall be credited to the open  interest  pocket
               and shall earn interest at the Current Rate of Interest in effect
               for that  interest  pocket.  Such  Contributions  or  transferred
               amounts,  during  the time  that  the  Current  Rate of  Interest
               exceeds the Guaranteed  Rate of Interest,  shall earn interest at
               such credited Current Rate of Interest for at least 1 year. After
               such 1-year  period,  AUL reserves  the right to declare,  at any
               time,  a new Current Rate of Interest to be applied to funds held
               within  that  interest  pocket.  Any  such  new  Current  Rate of
               Interest  must remain in effect for that  interest  pocket for at
               least 1 year.

          (b)  If AUL changes the Current Rate of Interest for new Contributions
               or new amounts  transferred  to the Fixed Interest  Account,  the
               previous open interest pocket shall close, and any  Contributions
               or amounts  transferred  on or after the  effective  date of such
               change shall be credited to a new open interest  pocket and shall
               earn  interest at the new Current  Rate of Interest in effect for
               such new open  interest  pocket.  Therefore,  at any given  time,
               various funds credited to a Participant  Account and allocated to
               the Fixed Interest  Account may be earning  interest at different
               Current Rates of Interest for different periods of time.

rate of 4.00%.

               invested in shares of the AUL  American  Equity  Portfolio of the
               Mutual Fund.

          (b)  Amounts  allocated  to  the  Bond  Investment  Account  shall  be
               invested  in shares of the AUL  American  Bond  Portfolio  of the
               Mutual Fund.

          (c)  Amounts allocated to the Money Market Investment Account shall be
               invested in shares of the AUL American Money Market  Portfolio of
               the Mutual Fund.

          (d)  Amounts  allocated  to the Managed  Investment  Account  shall be
               invested in shares of the AUL American  Managed  Portfolio of the

     3.1 Amount of Contributions:

     (a)  Contributions may vary in amount and frequency;  however, they must be
          at  least  equal  to  a  minimum  annual   Contribution  of  $300  per
          Participant  in any full  Contract  Year.  AUL may change such minimum
          annual  Contribution  acceptable  under  this  contract,  but any such
          change shall apply only to individuals  who become  Participants on or
          after the date of the change.  This contract will not terminate solely
          because a Contribution is not made for any Contract Year.

     (b)  Except for amounts eligible for rollover treatment under Code Sections
          402(a)(5),  402(a)(6),  402(a)(7), 403(a)(4), 403(b)(8), or 408(d)(3),
          Contributions  during a Participant's  taxable year (which is presumed
          to be a  calendar  year)  must be made in cash and may not  exceed the
          amounts described below (as adjusted by Code Section 408(a)):

          (1)  the lesser of $2,000 or 100% of  compensation  includible  in the
               Participant's  gross  income for such  taxable  year;  or (2) the
               lesser  of  $2,250  or 100%  of  compensation  includible  in the
               Participant's   gross   income  for  such   taxable   year  if  a
               Contribution is made on behalf of the Participant's  non-employed
               spouse  (no more than  $2,000  may be  allocated  to  either  the
               Participant or his spouse);  or (3) the lesser of $30,000 (or, if
               greater,  25% of the  dollar  limitation  in  effect  under  Code
               Section  415(b)(1)(A))  or 15% of  compensation  in the case of a
               simplified  employee  pension  (SEP, as described in Code Section
               408(k)) Contribution.


     (c)  Excess  Contributions  (plus gains or minus losses  thereon)  shall be
          withdrawn from a Participant  Account and returned to the  Participant
          upon   receipt  by  AUL  at  its  Home  Office  of  complete   written
          instructions  from the  Participant.  Such written  instructions  must
          include the amount to be withdrawn  and  returned,  and  certification
          that such Contributions  constitute Excess Contributions and that such
          returns  are  permitted  by  applicable  provisions  of the  Code  and
          Regulations issued  thereunder.  It shall not be the responsibility of
          AUL to determine  the existence or amount of Excess  Contributions  or
          gains or losses thereon,  or that returns of Excess  Contributions are
          permitted by  applicable  provisions of the Code and  Regulations.  In
          withdrawing and returning the identified  amount,  AUL may rely solely
          on such written instructions and certification.  Such a withdrawal and
          return of Excess Contributions shall not be subject to Section 4.8.

     (d)  Other refunds of  Contributions  shall be applied  before the close of
          the calendar year following the year of such refund toward the payment
          of future Contributions or the purchase of additional benefits.

     3.2 How Contributions Are Handled:

     (a)  When a  Contribution  is  received  at the  Home  Office,  it shall be
          credited to  Participant  Accounts  as directed in written  allocation
          instructions.
     (b)  The initial  Contribution  for a  Participant  shall be  credited  and
          allocated  to the  Participant  Account  no later  than  the  close of
          business on the second  business day of AUL after the later of (1) the
          business day that AUL receives  the initial  Contribution  at its Home
          Office, or (2) the business day that AUL receives, at its Home Office,
          the data required

                                       10
<PAGE>


          to establish the Participant   Account  and  allocation   instructions
          regarding the initial Contribution.  If the data required to establish
          the  Participant  Account and  allocation  instructions  regarding the
          initial Contribution are not received by AUL at its Home Office within
          5 business days after AUL first receives the initial Contribution, AUL
          shall return the initial Contribution to the contributing party unless
          consent is given to AUL to retain the initial  Contribution  until AUL
          receives the data and  allocation  instructions  for the  Participant.
          Alternatively,  if the data  required  to  establish  the  Participant
          Account and allocation instructions regarding the initial Contribution
          are not received by AUL at its Home Office when AUL first receives the
          initial  Contribution,  to the extent permitted by applicable law, AUL
          may allocate the initial  Contribution to the Money Market  Investment
          Account,  and shall transfer such amounts credited to the Money Market
          Investment Account according to the applicable allocation instructions
          upon receipt of the data required to establish the Participant Account
          and allocation instructions.

     (c)  All  Contributions  subsequent  to the initial  Contribution  shall be
          credited and  allocated  as of the close of business on the  Valuation
          Period in which AUL  receives  the  Contribution  at its Home  Office,
          provided that the  Contribution is received by 4:00 p.m. E.S.T. If the
          Contribution  is received after 4:00 p.m.  E.S.T.,  such  Contribution
          shall be deemed to be received, and shall be credited and allocated as
          of the close of business, on the next succeeding Valuation Period.

     (d)  Within any one  Participant  Account,  the amount so credited shall be
          allocated  to an  Investment  Option in  increments  of 10%,  25%,  or
          33-1/3%,  as elected by the  Participant in writing.  If no allocation
          instruction is made with respect to any Participant Account, AUL shall
          process such credits in  accordance  with the  allocation  instruction
          applicable to the immediately preceding Contribution.  If there should
          be no allocation instruction applicable to a portion of a Contribution
          other than the initial Contribution,  that amount shall be credited to
          the  Fixed  Interest   Account  until  such  time  as  an  appropriate
          allocation instruction is received, at which time such amount shall be
          withdrawn  from the Fixed Interest  Account and allocated  pursuant to
          such   instructions.   The   Participant   may  change  an  allocation
          instruction  with  respect to future  allocations  to his  Participant
          Account by giving new written  allocation  instructions  to AUL at its
          Home Office.

     3.3 Addition, Deletion, or Substitution of Investments:

     (a)  AUL reserves the right,  subject to compliance with applicable law, to
          make additions to, deletions from,  substitution  for, or combinations
          of,  the  securities  that are  held by the  Variable  Account  or any
          Investment  Account or that the  Variable  Account  or any  Investment
          Account may  purchase.  AUL reserves the right to eliminate the shares
          of any of the  eligible  Portfolios  and to  substitute  shares of, or
          interests  in,  another  Portfolio  of the  Mutual  Fund,  of  another
          open-end,  registered investment company, or other investment vehicle,
          for shares  already  purchased  or to be purchased in the future under
          the contract,  if the shares of any or all eligible  Portfolios are no
          longer  available for investment,  or if, in AUL's  judgment,  further
          investment in any or all eligible Portfolios becomes  inappropriate in
          view of the purposes of the Variable  Account or the  contract.  Where
          required under  applicable  law, AUL will not substitute any shares in
          the  Variable  Account  or  any  Investment  Account  without  notice,
          Participant approval, or prior approval of the Securities and Exchange
          Commission or a state insurance  commissioner,  and without  following
          the  filing  or  other  procedures  established  by  applicable  state
          insurance  regulators.  Nothing  contained  herein  shall  prevent the
          Variable  Account from purchasing other securities for other series or
          classes of contracts, or from effecting a conversion


                                       11
<PAGE>


          between series  or classes  of contracts on the basis of requests made
          by a majority of participants or as permitted by federal law.

     (b)  AUL reserves the right to establish  additional  Investment  Accounts,
          each of which would invest in a new  Portfolio of the Mutual Fund,  or
          in  other  securities,  investment  vehicles,  or  shares  of  another
          diversified open-end management  investment company or series thereof.
          AUL reserves the right to  eliminate  or combine  existing  Investment
          Accounts if, in its sole  discretion,  marketing,  tax, or  investment
          conditions  so warrant.  AUL also  reserves the right to provide other
          Investment  Options  under this  contract at any time.  Subject to any
          required  regulatory  approvals,  AUL  reserves  the right to transfer
          assets from any Investment  Account to another separate account of AUL
          or Investment Account.

     (c)  In the  event  of  any  such  substitution  or  change,  AUL  may,  by
          appropriate  amendment,  make such changes in this  contract as may be
          necessary or appropriate to reflect such  substitution  or change.  If
          deemed  by AUL to be in the best  interests  of  persons  or  entities
          having voting rights under this contract,  the Variable Account may be
          operated  as a  management  investment  company  under The  Investment
          Company  Act of 1940 or any other  form  permitted  by law,  it may be
          deregistered  in the event  such  registration  is no longer  required
          under The  Investment  Company Act of 1940, or it may be combined with
          other separate accounts of AUL or an affiliate  thereof.  AUL may take
          such action as is necessary to comply with,  or to obtain,  exemptions
          from  the  Securities  and  Exchange  Commission  with  regard  to the
          Variable Account.  Subject to compliance with applicable law, AUL also
          may  combine  one or more  Investment  Accounts  and may  establish  a
          committee,  board, or other group to manage one or more aspects of the
          operation of the Variable Account.

     3.4 Transfers:

     (a)  Subject to the  limitations of Section 3.5, the Participant may direct
          AUL  at its  Home  Office  to  transfer  the  amounts  credited  to an
          Investment   Option  to  any  other   Investment   Option  during  the
          Accumulation  Period.  For any transfer  from an  Investment  Account,
          Accumulation  Units shall be valued as of the close of business on the
          Valuation Date that AUL receives the Participant's direction, provided
          that AUL receives such direction by 4:00 p.m. E.S.T. on that Valuation
          Date.  If such  direction  is received  after 4:00 p.m.  E.S.T.,  such
          transfer  shall be  effective  as of the close of business on the next
          succeeding Valuation Date.

     (b)  AUL shall make the transfer as requested by the  Participant  within 7
          days from the date a proper  request  is  received  by AUL at its Home
          Office,  except  as AUL may be  permitted  to defer  such  payment  of
          amounts  withdrawn  from  the  Variable  Account  in  accordance  with
          appropriate  provisions of the federal  securities  laws. AUL reserves
          the right to defer a  transfer  of  amounts  from the  Fixed  Interest
          Account  for a period of 6 months  after  AUL  receives  the  transfer
          request at its Home Office.

     (c)  All  transfers  from the  Fixed  Interest  Account  to any  Investment
          Account shall be made on a first-in/first-out accounting basis.

     3.5 Limitations on Transfers:

     (a)  The  Participant  may  not  direct  a  transfer  with  regard  to  his
          Participant Account's share of any Investment Option in an amount less
          than $500 or the  Participant  Account's  entire  share,  if less than
          $500. If such a transfer reduces the Participant  Account's  remaining
          share of an Investment  Option to less than $500, the entire remaining
          share shall also be transferred.

     (b)  Amounts  transferred  from the Fixed  Interest  Account on behalf of a
          Participant  during  any  Contract  Year  shall not  exceed 20% of the
          Participant  Account's share of the Fixed Interest Account  determined
          as  of  the  last  Contract  Anniversary  preceding  the  request  for
          transfer,  or the  Participant  Account's  entire  share of the  Fixed
          Interest  Account  if such  share  would be less than  $500  after the
          transfer.  (c) Amounts under this contract which have been transferred
          from  other  group  annuity  contracts,   whether  issued  by  AUL  or
          otherwise,  shall be allocated  pursuant to the  provisions of Section
          3.2.

     (d)  AUL  reserves  the  right to  change  the  limitation  on the  minimum
          transfer,  to change  the limit on  remaining  balances,  to limit the
          number and frequency of transfers,  to suspend the transfer  privilege
          provided  in  Sections  3.4 and  3.5,  and to  impose  a  charge  on a
          transfer.

          than $500 or the  Participant  Account's  entire  share,  if less than
          $500. If such a transfer reduces the Participant  Account's  remaining

          share shall also be transferred.

     (b)  Amounts  transferred  from the Fixed  Interest  Account on behalf of a
          Participant  during  any  Contract  Year  shall not  exceed 20% of the

          Interest  Account  if such  share  would be less than  $500  after the
          transfer.

     (c)  Amounts under this  contract  which have been  transferred  from other
          group annuity contracts,  whether issued by AUL or otherwise, shall be

          provided in Sections  3.4 and 3.5,  and to impose a charge of not more
          than $25 on a transfer.  AUL  reserves the right to change the maximum
          limit on such transfer  charge upon delivery of written  notice to the
          Contractholder.  Any such change in the maximum limit shall apply only
          to transfers by an individual  who becomes a  Participant  on or after
          the  effective  date of such  change,  and shall apply as long as that
          individual remains a Participant.

     4.1 Election of Annuity Options: At the written request of the Participant,
AUL shall apply all or a portion of the Account  Value  (subject to Section 6.5)
of the Participant Account for the purpose of providing a fixed payment annuity.
Upon receipt of such request,  AUL is hereby  authorized by such  Participant to
value and transfer the Participant  Account's  share of the Variable  Account to
the Fixed Interest Account as of the date that AUL receives such written request
at its Home Office. Such transferred amounts shall be held in the Fixed Interest
Account until the  Participant's  Annuity  Commencement  Date.  The  Participant
request  shall include  certification  as to the purpose for the annuity and the
election  of one of the  following  annuity  options.  The amount of the annuity
shall be computed  from the Table of Immediate  Annuities  then included in this
contract, except as provided under Section 4.4.

     4.2 Annuity Options:


     (a)  Life  Annuity.  The monthly  annuity shall be payable to the annuitant
          for as long as the  annuitant  lives,  and  shall  end  with  the last
          monthly payment before the death of the annuitant.

     (b)  Certain and Life Annuity.  The monthly annuity shall be payable to the
          annuitant for as long as the annuitant  lives.  If the annuitant  dies
          before  receiving  payments  for the certain  period (5, 10, 15, or 20
          years, as specified in the election),  any remaining  payments for the
          balance  of the  certain  period  shall  be  paid  to the  annuitant's
          beneficiary.

     (c)  Survivorship  Annuity.  The  monthly  annuity  shall be payable to the
          annuitant for as long as the annuitant  lives.  After the death of the
          annuitant,  a portion (all, 2/3, or 1/2, as specified in the election)
          of the  annuitant's  monthly  annuity shall be paid to the  contingent
          annuitant  named  in the  election  for  as  long  as  the  contingent
          annuitant lives. An election of this option is automatically cancelled
          if either the Participant or the contingent  annuitant dies before the
          Annuity Commencement Date.

     (d)  Unit Refund Life Annuity.  The monthly annuity shall be payable to the
          annuitant for as long as the annuitant  lives,  and shall end with the
          last monthly  payment  before the death of the  annuitant.  If, at the
          death of the  annuitant,  the sum of the monthly  payments  previously
          received  is less than the  amount  applied to  provide  the  annuity,
          monthly  payments of the same amount shall continue to the annuitant's
          beneficiary  until the total of the monthly  payments  received equals
          such amount.

     (e)  Fixed  Period.  The monthly  annuity shall be payable to the annuitant
          for a fixed  period  of time  (not  less than 5 years nor more than 30
          years,  as  specified  in  the  election).  If,  at the  death  of the
          annuitant,  payments  have been made for less than the selected  fixed
          period, monthly annuity payments to the annuitant's  beneficiary shall
          be continued during the remainder of such fixed period.

     (f)  Any other  options  made  available  by AUL at the time a  Participant
          exercises his option to elect an annuity.

If the  annuity  option  selected  is not  included  in the  attached  Table  of
Immediate  Annuities,  the  amount of  monthly  annuity  shall be based on rates
determined in the same manner as those found in the Table.

If no annuity option  election for a Participant has been received by AUL at its
Home Office at least 30 days prior to the Annuity Commencement Date, the Account
Value (subject to Section 6.5) of his Participant Account shall be applied under
(b)  above as a 10 Year  Certain  and Life  Annuity.  AUL must  receive  written
notification  of such Annuity  Commencement  Date,  written  designation  of the
contingent annuitant or beneficiary, and any election forms needed in connection
with any annuity option provided in this Section.

Distributions  shall be made in accordance  with the requirement of Code Section
401(a)(9) and the Regulations issued thereunder. Under these requirements, in no
event shall any option elected provide annuity benefits to the Participant or to
the  Participant  and the contingent  annuitant which would extend for a certain
period  beyond  the  life  expectancy  of such  Participant  or the  joint  life
expectancy of such  Participant and such  contingent  annuitant as determined on
the Annuity  Commencement  Date.  Life  expectancy  for purposes of Code Section
401(a)(9) and the  Regulations  issued  thereunder  shall be computed  using the
expected return multiples in Tables V and VI of Section 1.72-9 of the Income Tax
Regulations. Any periodic payments made under Section 401(a)(9) shall be made at
intervals of no longer than one year. In addition,  any such  periodic  payments
must be either nonincreasing or they may increase only as provided in Q&A F-3 of
section 1.401(a)(9)-1 of the Proposed Income Tax Regulations.

     4.3 Guaranteed Rate of Interest: The retirement annuity options provided in
this Article and illustrated  in the attached  Table of Immediate  Annuities are
based on a guaranteed interest rate of 4.00% compounded annually.

     4.4 Alternate  Nonparticipating  Retirement  Annuity:  Any annuity  elected
shall be provided at whatever current single premium nonparticipating  immediate
annuity rates are available  under this class of group annuity  contract if such
rates produce a higher  income than that  provided  under the Table of Immediate
Annuities provided in this contract.

     4.5 Minimum Payments:  If the total Account Value is less than $2,000, such
value shall be paid in a lump sum to the annuitant  rather than annuitized under
the  annuity  options  provided  in Section  4.2.  Additionally,  if the monthly
annuity is less than AUL's then current  established  minimum,  AUL reserves the
right to make payments on a less frequent basis.

     4.6 Due Proof of Date of Birth and  Survival:  Before  commencing  payments
under any annuity,  AUL may require  proof of the date of birth of any annuitant
and may require  due proof that any  annuitant  is living  before the payment of
each or any installment under the option.

     4.7 Death Benefits:

     (a)  Upon   receipt  of  written   instructions   from  the   Participant's
          beneficiary  (or, if  applicable,  the  secondary  beneficiary  of the
          Participant)  and  of  due  proof  of  the   Participant's   (and,  if
          applicable, the beneficiary's) death during the Accumulation Period at
          its Home Office,  AUL shall apply the Account Value of the Participant
          Account  for the  purpose  of  providing  a death  benefit.  The death
          benefit shall be paid to the beneficiary  last properly  designated in
          writing to AUL at its Home Office by the Participant,  or, if there is
          no  designated  beneficiary  living  on the date of the  Participant's
          death, to the  Participant's  estate.  If any  beneficiary  dies while
          receiving  payments and no  beneficiary  is  designated to receive any
          remaining  payments,  such  remaining  payments  shall  be made to the
          deceased beneficiary's estate.

                                       16
<PAGE>


     (b)  The  Account  Value  to be  applied  pursuant  to (a)  above  shall be
          determined  as of the  close  of  business  on the  later  of (1)  the
          Valuation Date that AUL receives such written instructions at its Home
          Office,  or (2) the Valuation Date that AUL receives such due proof of
          death at its Home Office,  provided that such written  instructions or
          due proof of death  received on the later of (1) or (2) above  are(is)
          received by 4:00 p.m. E.S.T. If the written  instructions or due proof
          of death  received on the later of (1) or (2) above  are(is)  received
          after 4:00 p.m.  E.S.T.,  such valuation shall be made as of the close
          of business on the next succeeding Valuation Date.

     (c)  (1)  The  benefit  shall  be  payable in  accordance  with  one of the
               following  provisions  as  elected  by  the  Participant  or  the
               beneficiary if the Participant did not make an election:

               (i)  The entire  Account Value to be applied shall be paid to the
                    beneficiary in a single sum or by another  elected method on
                    or before  December 31 of the calendar  year which  contains
                    the  fifth  anniversary  of the  date  of the  Participant's
                    death; or

               (ii) The benefit shall be paid as an annuity in  accordance  with
                    the Annuity  Options  shown in Section 4.2 over a period not
                    to exceed the life or life expectancy of the beneficiary. If
                    the beneficiary is not the  Participant's  surviving spouse,
                    the  annuity  must  begin on or  before  December  31 of the
                    calendar  year  immediately  following  the calendar year in
                    which  the  Participant  died.  If  the  beneficiary  is the
                    Participant's  surviving  spouse,  such  spouse may elect to
                    receive equal or substantially  equal payments over the life
                    or life  expectancy  of such spouse  commencing  at any date
                    prior to the later of (1) December 31 of the  calendar  year
                    immediately   following  the  calendar  year  in  which  the
                    Participant died, or (2) December 31 of the calendar year in
                    which the  Participant  would have attained age 70 1/2. Such
                    spousal  election  must be made no later than the earlier of
                    December  31 of  the  calendar  year  containing  the  fifth
                    anniversary   of  the   Participant's   death  or  the  date
                    distributions   are  required  to  begin   pursuant  to  the
                    preceding  sentence.  The  surviving  spouse may  accelerate
                    these  payments at any time by  increasing  the frequency or
                    amount of such payments.

                    If the  beneficiary  is the  Participant's surviving spouse,
                    such spouse may treat the  Participant Account as his or her
                    own individual retirement  arrangement (IRA). This election
                    will be  deemed  to  have been made if such surviving spouse
                    makes a regular IRA Contribution under this contract,  makes
                    a rollover  to or from  this contract, or fails to elect any
                    of the above three provisions.

               (iii) Distributions  under this section  are  considered  to have
                    begun if distributions are made on account of the individual
                    reaching his or her required  beginning  date or if prior to
                    the  required  beginning  date   distributions   irrevocably
                    commence to an individual over a period  permitted and in an
                    annuity form  acceptable  under section  1.401(a)(9)  of the
                    Regulations.

                                       17
<PAGE>


          (2)  If a Participant dies on or after his Annuity  Commencement Date,
               any interest remaining under the Annuity Option selected shall be
               paid at least as rapidly as prior to the Participant's death.

          (3)  If  payment  is to be made in a cash lump sum,  payment  shall be
               made within 7 days of the date of valuation,  as determined above
               in this  Section,  except as AUL may be  permitted  to defer such
               payment  of  amounts   derived  from  the  Variable   Account  in
               accordance with the provisions of federal  securities laws. Also,
               AUL reserves the right to defer the payment of amounts  withdrawn
               from the Fixed  Interest  Account for a period of 6 months  after
               AUL receives written instructions at its Home Office.

     4.8 Withdrawal Benefits:

     (a)  Except  as stated  below,  a  Participant,  upon  submitting  a proper
          written request to AUL at its Home Office,  may direct AUL to withdraw
          all or a portion  of the  Account  Value  (subject  to the  Withdrawal
          Charge) of his Participant Account.

     (b)  Withdrawals from a Participant Account's share of an Investment Option
          may not be made in an  amount  less  than the  smaller  of $500 or the
          Participant  Account's  entire share of the  Investment  Option.  If a
          withdrawal  reduces the  Participant  Account's share of an Investment
          Option  to  less  than  $500,  such  remaining  share  shall  also  be
          withdrawn.

     (c)  A withdrawal request shall be effective as of the close of business on
          the  Valuation  Date that AUL  receives  a proper  written  withdrawal
          request at its Home Office, provided that AUL receives such request by
          4:00 p.m.  E.S.T.  on that Valuation Date. If such request is received
          after 4:00 p.m.  E.S.T.,  such  request  shall be  effective as of the
          close of business on the next succeeding Valuation Date.

     (d)  The  Account  Value to be applied  pursuant to this  Section  shall be
          determined  as of the  applicable  Valuation  Date  determined  in (c)
          above.  If the  entire  Account  Value  of a  Participant  Account  is
          withdrawn,  the Participant shall be paid the Withdrawal Value. If the
          Participant  requests that a specified  percentage or dollar amount be
          paid to the  Participant,  AUL  shall  withdraw  from the  Participant
          Account an amount equal to the dollar amount to be paid divided by the
          difference  between 1 and the  decimal  equivalent  of the  applicable
          Withdrawal  Charge.  Notwithstanding  the  previous  sentence,  in any
          Contract  Year the  Participant  may withdraw up to 10% of the Account
          Value of his  Participant  Account  determined as of the last Contract
          Anniversary   preceding  the  request  for  the   withdrawal   without
          application  of any  Withdrawal  Charge,  provided that 12 months have
          elapsed from the date that the  Participant's  first  Contribution  is
          credited  to his  Participant  Account  by AUL to  the  date  of  such
          withdrawal.

     (e)  AUL shall pay such amount in a cash lump sum to the Participant.  Such
          cash  lump sum  will be paid  within  7 days  from  the date  that AUL
          receives the withdrawal request at its Home Office,  except as AUL may
          be  permitted  to defer such  payment of  amounts  withdrawn  from the
          Variable  Account in  accordance  with  appropriate  provisions of the
          federal  securities  laws. AUL reserves the right to defer the payment
          of amounts with drawn from the Fixed Interest  Account for a period of
          up to 6 months after AUL receives the  withdrawal  request at its Home
          Office.

<PAGE>

     (f)  Withdrawals  from a Participant  Account's share of the Fixed Interest
          Account shall be made on a  first-in/first-out  basis so that all or a
          portion of the amounts credited to the Participant  Account's share of
          the Fixed Interest  Account which have been on deposit for the longest
          period of time,  as well as the interest  credited  thereon,  shall be
          withdrawn first.

                             ARTICLE 5 - VALUATIONS


     5.1 Time of  Valuation:  All  assets of each  Portfolio  shall be valued as
provided in the prospectus for the Mutual Fund as such prospectus may be amended
or supplemented from time to time.

     5.2  Accumulation  Units:  Any amounts that are allocated to any Investment
Account on behalf of a Participant shall be credited to his Participant  Account
in the form of  Accumulation  Units on the basis of the  value of such  units in
that  Investment  Account  as of the end of the  Valuation  Period on which such
amounts are received by AUL at its Home  Office.  Such  crediting  shall be made
separately  for amounts  allocated  to each  Investment  Account.  The number of
Accumulation  Units in each  Investment  Account  credited  to each  Participant
Account as of any  Valuation  Period shall be determined by dividing the amounts
allocated to that  Investment  Account for that  Participant  Account as of such
Valuation Period by the dollar value of one Accumulation Unit in that Investment
Account as of the close of  business on the  applicable  Valuation  Period.  The
number  of  Accumulation  Units  thus  determined  shall not be  changed  by any
subsequent change in the dollar value of the Accumulation Units.

     5.3 Value of Accumulation  Units: The value of an Accumulation Unit in each
Investment  Account was  established at $1.00 as of April 12, 1990. The value of
an  Accumulation  Unit in each  Investment  Account as of any  Valuation  Period
thereafter  is  equal  to the  dollar  value  of one  Accumulation  Unit in that
Investment Account as of the immediately  preceding  Valuation Period multiplied
by the Net  Investment  Factor,  as defined in Section 5.4, for that  Investment
Account for the current Valuation Period.  The value of an Accumulation Unit for
each  Investment  Account shall be determined for each  Valuation  Period before
giving  effect  to  any  additions,   withdrawals,   or  transfers.  After  such
determination,  the additions,  withdrawals, or transfers which are effective as
of that day shall then be made.

     5.4 Determining the Net Investment  Factor:  The Net Investment  Factor for
each Investment  Account for any Valuation  Period is determined by dividing (a)
by (b), and then subtracting (c) from that result, where:

     (a)  is equal to:

          (l)  the net asset value of a Portfolio  share held in the  Investment
               Account determined as of the end of the current Valuation Period,
               plus

          (2)  the per share  amount of any dividend or other  distribution,  if
               any, paid by the Portfolio during the current  Valuation  Period,
               plus or minus

          (3)  any credit or charge for any taxes  paid or  reserved  for by AUL
               during the current  Valuation  Period which are determined by AUL
               to be attributable to operation of the Investment Account;

     (b)  is the net asset  value of a  Portfolio  share held in the  Investment
          Account  determined  as  of  the  end  of  the  immediately  preceding
          Valuation Period; and

     (c)  is a daily  charge  factor  determined  by AUL to reflect  the charges
          assessed  against the assets of the  Investment  Account for mortality
          and expense risks.


     5.5  Determining  the  Value  of Each  Participant  Account's  Share of any
Investment  Account:  The  value  of each  Participant  Account's  share  of any
Investment  Account as of any Valuation  Date shall be determined by multiplying
the  Participant  Account's  aggregate  Accumulation  Units  in that  Investment
Account as of such Valuation Date by the dollar value of one  Accumulation  Unit
in  that  Investment  Account  as of  such  Valuation  Date.  The  value  of the
Participant  Account's share of any Investment Account as of any date other than
a Valuation Date is equal to the value of its share of that  Investment  Account
as of the immediately preceding Valuation Date.

     5.5  Determining  the  Value  of Each  Participant  Account's  Share of any
Investment  Account:  The  value  of each  Participant  Account's  share  of any
Investment  Account as of any Valuation  Date shall be determined by multiplying
the  Participant  Account's  aggregate  Accumulation  Units  in that  Investment
Account as of such Valuation Date by the dollar value of one  Accumulation  Unit
in  that  Investment  Account  as of  such  Valuation  Date.  The  value  of the
Participant  Account's share of any Investment Account as of any date other than
a Valuation Date is equal to the value of its share of that  Investment  Account
as of the immediately  preceding  Valuation Date. The value of each  Participant
Account's share of the Fixed Interest  Account as of any Valuation Date shall be
equal to the current  balance of the  Participant  Account's  share of the Fixed
Interest Account on that date.

                            ARTICLE 6 - OTHER CHARGES


     6.1  Mortality  Risk and Expense  Risk  Charges:  AUL shall  deduct a daily
mortality  risk  charge  and a daily  expense  risk  charge  equal to the  daily
equivalent of an annual  combined  charge of 1.25% against the average daily net
assets of each Investment Account.

     6.2 Investment  Management  Charge: The Mutual Fund shall pay an investment
advisory fee and certain other  expenses,  which may include its operational and
organizational  expenses,  as described in the  current  prospectus as it may be
amended or supplemented  from time to time. These expenses may vary from year to

fee and other expenses which are deducted from the assets of such Portfolio.

     6.3 Administrative  Charge:  AUL shall deduct an administrative  charge per
Contract  Quarter  equal to the lesser of $7.50 or 0.5% of the Account  Value on
the last day of each Contract Quarter from each Participant Account in existence
on such day for as long as the  Participant  Account  is in  effect  during  the
Accumulation  Period. This charge is to be prorated among each subaccount of the
Participant  Account which  corresponds to each Investment Option utilized under
this  contract  by  that  Participant  Account.  If  the  entire  balance  of  a
Participant  Account is applied or withdrawn before the last day of the Contract
Quarter  pursuant  to  Sections  4.1,  4.7, or 4.8,  the  administrative  charge
attributable  to the period of time which has elapsed since the first day of the
Contract  Quarter in which such application or withdrawal of funds is made shall
not be deducted from the amount applied or withdrawn.

     6.4  Transfer  Charge:  AUL  reserves the right to deduct a charge for each
transfer  transaction  pursuant to Section  3.4.  This charge  would be prorated
among the Investment  Options from which the amounts are transferred in the same
proportion that the amount  transferred from the Investment  Option bears to the
total amount transferred from all Investment Options.

     6.5 Other Charges: AUL reserves the right to deduct the appropriate premium
tax charge at the time annuity payments commence pursuant to Section 4.1 or such
other time that premium  taxes are incurred by AUL. AUL also  reserves the right
to deduct the  appropriate  charges for  federal,  state,  or local income taxes
incurred by AUL that are attributable to the Variable Account and its Investment
Accounts.

     6.6  Reduction  or Waiver of Certain  Charges:  AUL may reduce or waive the
amount  of the  Withdrawal  Charge or the  administrative  charge  discussed  in
Section 6.3 where the expenses  associated with the sale of this contract or the
administrative  costs  associated with this contract are reduced,  or where this
contract is sold to the directors or employees of AUL or any of its  affiliates,
or to directors or any employees of the Mutual Fund.

Contract  Quarter  equal to the lesser of $7.50 or 0.5% of the Account  Value on
the last day of each Contract Quarter from each Participant Account in existence
on such day for so long as the  Participant  Account  is in  effect  during  the
Accumulation  Period. This charge is to be prorated among each subaccount of the
Participant  Account which  corresponds to each Investment Option utilized under
this  contract  by that  Participant  Account.  However,  in no event  shall any
portion of the  annual  charge for a  Contract  Year  attributable  to the Fixed
Interest Account subaccount of the Participant  Account exceed the amount of the
Contributions  allocated  to such  Fixed  Interest  Account  subaccount  for the
Participant  during such Contract Year plus interest earned during such Contract
Year on amounts held in such Fixed Interest  Account  subaccount.  If the entire
balance of a Participant  Account is applied or withdrawn before the last day of
the Contract Quarter  pursuant to Sections 4.1, 4.7, or 4.8, the  administrative
charge  attributable to the period of time which has elapsed since the first day

Accumulation  Period. This charge is to be prorated among each subaccount of the
Participant  Account which  corresponds to each Investment Option utilized under
this  contract  by  that  Participant  Account.  If  the  entire  balance  of  a
Participant  Account is applied or withdrawn before the last day of the Contract
Quarter  pursuant  to  Sections  4.1,  4.7, or 4.8,  the  administrative  charge
attributable  to the period of time which has elapsed since the first day of the

not be deducted from the amount applied or withdrawn.

     6.4  Transfer  Charge:  AUL  reserves  the right to deduct a charge (not to
exceed $25) for each transfer  transaction  pursuant to Section 3.4. This charge
would be  prorated  among the  Investment  Options  from which the  amounts  are
transferred  in the  same  proportion  that  the  amount  transferred  from  the
Investment  Option bears to the total  amount  transferred  from all  Investment
Options.

     6.5 Other Charges: AUL reserves the right to deduct the appropriate premium
tax charge at the time annuity payments commence pursuant to Section 4.1 or such
other time that premium  taxes are incurred by AUL. AUL also  reserves the right

incurred by AUL that are attributable to the Variable Account and its Investment
Accounts.

     6.6  Reduction  or Waiver of Certain  Charges:  AUL may reduce or waive the
amount  of the  Withdrawal  Charge or the  administrative  charge  discussed  in
Section 6.3 where the expenses  associated with the sale of this contract or the
administrative  costs  associated with this contract are reduced,  or where this
contract is sold to the directors or employees of AUL or any of its  affiliates,

     8.15 Voting:

     (a)  AUL is the legal  owner of the shares of the  Mutual  Fund held by the
          Investment Accounts of the Variable Account. AUL shall exercise voting
          rights  attributable  to the  shares  of  each  Portfolio  held in the
          Investment  Accounts  at  any  regular  and  special  meetings  of the
          shareholders  of the  Mutual  Fund on  matters  requiring  shareholder
          voting under The  Investment  Company Act of l940 or other  applicable
          laws.  AUL shall  exercise  these voting rights based on  instructions
          received  from  persons  having the voting  interest in  corresponding
          Investment   Accounts  of  the  Variable  Account.   However,  if  The
          Investment Company Act of l940 or any regulations thereunder should be
          amended, or if the present  interpretation  thereof should change, and
          as a result AUL determines  that it is permitted to vote the shares of
          the Mutual Fund in its own right, it may elect to do so. AUL will vote
          shares of any Investment Account, if any, that it owns beneficially in
          its own  discretion,  except that if the Mutual Fund offers its shares
          to any insurance  company  separate  account that funds  variable life
          insurance  contracts or if otherwise  required by applicable  law, AUL
          will  vote  its  own  shares  in the  same  proportion  as the  voting
          instructions  that are received in a timely  manner for  contracts and
          Participant Accounts participating in the Investment Account.

     (b)  The persons  having the voting  interest  under this  contract are the
          Participants.  Unless otherwise required by applicable law, the number
          of Mutual Fund shares of a  particular  Portfolio  as to which  voting
          instructions  may be given to AUL is  determined by dividing the value
          of all of  the  Accumulation  Units  of the  corresponding  Investment
          Account  attributable to this contract on a particular date by the net
          asset  value  per  share  of  that  Portfolio  as of  the  same  date.
          Fractional  votes  will be  counted.  The  number of votes as to which
          voting  instructions  may be given will be  determined  as of the date
          coincident   with  the  date   established  by  the  Mutual  Fund  for
          determining shareholders eligible to vote at the meeting of the Mutual
          Fund.  If required by the  Securities  and  Exchange  Commission,  AUL
          reserves  the right to  determine  in a  different  fashion the voting
          rights attributable to the shares of the Mutual Fund.



                                       29
<PAGE>

     (c)  Voting rights attributable to this contract for which no timely voting
          instructions  are received will be voted by AUL in the same proportion
          as the voting  instructions  which are received in a timely manner for
          all  contracts  and  Participant   Accounts   participating   in  that
          Investment Account.

     (d)  Neither the  Variable  Account nor AUL is under any duty to inquire as
          to the  instructions  received or the  authority  of  Contractholders,
          Participants, or others to instruct the voting of Mutual Fund shares.

     (e)  Every person or entity  having such voting  rights shall  receive such
          reports or prospectuses  concerning the Variable Account or the Mutual
          Fund as may be required by applicable federal law.

     8.16  Acceptance of New  Participants  or  Contributions.  AUL reserves the
right to refuse to accept new Participants or new Contributions to this contract
at any time.  AUL shall have the right to refuse to accept  Contributions  as of
the last day of the second month  following the date that written notice to this
effect is delivered to any  contributing  Participant or to any  Participant for
whom Contributions are being made.

     8.17 Nonforfeitability and Nontransferability:  The entire Withdrawal Value
of a  Participant  Account under this contract  shall be  nonforfeitable  at all
times.  No sum payable under this contract with respect to a Participant  may be
sold, assigned,  discounted,  or pledged as collateral for a loan or as security
for the  performance  of an obligation or for any other purpose to any person or
entity other than AUL. In addition,  to the extent permitted by law, no such sum
shall in any way be subject to legal process  requiring the payment of any claim
against the payee.

     8.18  Termination:  This contract shall  automatically  terminate as of the
date that there are no Participant Accounts maintained hereunder.

     8.19 Notice of Annual Meeting of Members: The regular annual meeting of the
members of AUL (i.e.,  contractholders)  shall be held at its principal place of
business  on the  third  Thursday  in  February  of each year at the hour of ten
o'clock A.M. Elections for directors shall be held at such annual meeting.

                  AMERICAN UNITED LIFE INSURANCE COMPANY (AUL)

PEOPLES BANK & TRUST  COMPANY AS  CUSTODIAN ON BEHALF OF ANY PERSON  ELIGIBLE TO
PARTICIPATE  IN  AN  IRC  408  INDIVIDUAL   RETIREMENT  ANNUITY  WHO  BECOMES  A
PARTICIPANT UNDER THIS CONTRACT AND SUCH SUCCESSOR CUSTODIAN AS MAY BE APPOINTED
FROM TIME TO TIME (THE CONTRACTHOLDER)

            The Effective Date of this Amendment is JANUARY 1, 2000.

AUL and the Contractholder  hereby agree, by signing below, that the Contract is
amended as follows:

By deleting the term "death benefit"  wherever it appears in the Contract and by
substituting "Death Benefit" in lieu thereof.

And by deleting the corresponding Sections or Subsections of the Contract and by
substituting  the following  Sections or  Subsections  in lieu  thereof,  and by
making  any  required  corresponding  changes  in the Table of  Contents  of the
Contract:

1.10A "Death Benefit" is the greater of:

     (a)  the  Participant's  Account  Value as of the date the Death Benefit is
          calculated, or

     (b)  (1) the  Guaranteed  Minimum  Death  Benefit  (GMDB)  on the  Contract
          Anniversary immediately preceding the date of the Participant's death;
          increased by

          (2)  any  Contributions  made  for  the  Participant  since  the  last
               Contract Anniversary; and reduced proportionately to reflect

          (3)  any  withdrawals  for the  Participant  since  the last  Contract
               Anniversary.

1.12AThe  "Guaranteed  Minimum  Death  Benefit"  or  "GMDB"  prior to the  first
     Contract  Anniversary is equal to the Contributions  made for a Participant
     minus any of his  withdrawals.  On each Contract  Anniversary  prior to, or
     concurrent with, the Participant's  date of death, the GMDB is reset, based
     on the age of the Participant on his last birthday, as follows:

     (a)  For  Participants  less than 81 years of age,  the GMDB is the greater
          of:

          (1)  the  Participant's  Account  Value  as of  the  current  Contract
               Anniversary, or

          (2)  (i)  the   GMDB  as  of  the   immediately   preceding   Contract
               Anniversary; increased by

               (ii) any  Contributions   made  for  the  Participant  since  the
                    immediately  preceding  Contract  Anniversary;  and  reduced
                    proportionately to reflect

               (iii)any withdrawals  for the  Participant  since the immediately
                    preceding Contract Anniversary.


P-12867.NOLOADIRAGMDB.AMD.1
<PAGE>


     (b)  For Participants 81 years of age or older, the GMDB is equal to:

          (1)  the GMDB as of the immediately  preceding  Contract  Anniversary;
               increased by

          (2)  any Contributions  made for the Participant since the immediately
               preceding Contract  Anniversary;  and reduced  proportionately to
               reflect

          (3)  any  withdrawals  for  the  Participant   since  the  immediately
               preceding Contract Anniversary.

As of the  Participant's  date of death, the GMDB ceases to increase or decrease
in value.

1.13 "Guaranteed Rate of Interest" means interest at an annual effective rate of
     3.00%.

6.3  Administrative  Charge:  AUL deducts an administrative  charge per Contract
     Quarter  equal to the lesser of $7.50 or 0.5% of the  Account  Value on the
     last  day of  each  Contract  Quarter  from  each  Participant  Account  in
     existence on that day for as long as the Participant  Account is in effect.
     This  charge is to be prorated  among each  subaccount  of the  Participant
     Account which  corresponds to each  Investment  Option  utilized under this
     contract  by  that  Participant   Account.  If  the  entire  balance  of  a
     Participant   Account  is  withdrawn   pursuant  to  this   contract,   the
     administrative  charge attributable to the period of time which has elapsed
     since the first day of the  Contract  Quarter  in which the  withdrawal  of
     funds is made is not deducted from the amount withdrawn.

There is no charge  for a  Participant  for any  Contract  Quarter  in which the
Participant's  Account  Value on the last day of that  quarter is  greater  than
$25,000.

                                   AMENDMENT
                                     TO THE
                               AUL AMERICAN SERIES
                    IRA MULTIPLE-FUND GROUP VARIABLE ANNUITY
                     CONTRACT NUMBER GA XXXXX (THE CONTRACT)
                                    ISSUED BY
                  AMERICAN UNITED LIFE INSURANCE COMPANY (AUL)
                                       TO
PEOPLES BANK & TRUST  COMPANY AS  CUSTODIAN ON BEHALF OF ANY PERSON  ELIGIBLE TO
PARTICIPATE  IN  AN  IRC  408  INDIVIDUAL   RETIREMENT  ANNUITY  WHO  BECOMES  A
PARTICIPANT UNDER THIS CONTRACT AND SUCH SUCCESSOR CUSTODIAN AS MAY BE APPOINTED
FROM TIME TO TIME (THE CONTRACTHOLDER)

            The Effective Date of this Amendment is JANUARY 1, 2000.

AUL and the Contractholder  hereby agree, by signing below, that the Contract is
amended as follows:

By deleting the term "death benefit"  wherever it appears in the Contract and by
substituting "Death Benefit" in lieu thereof.

And by deleting the corresponding Sections or Subsections of the Contract and by
substituting  the following  Sections or  Subsections  in lieu  thereof,  and by
making  any  required  corresponding  changes  in the Table of  Contents  of the
Contract:

1.10A "Death Benefit" is the greater of:

     (a)  the  Participant's  Account  Value as of the date the Death Benefit is
          calculated, or

     (b)  (1) the  Guaranteed  Minimum  Death  Benefit  (GMDB)  on the  Contract
          Anniversary immediately preceding the date of the Participant's death;
          increased by

          (2)  any  Contributions  made  for  the  Participant  since  the  last
               Contract Anniversary; and reduced proportionately to reflect

          (3)  any  withdrawals  for the  Participant  since  the last  Contract
               Anniversary.

1.12AThe  "Guaranteed  Minimum  Death  Benefit"  or  "GMDB"  prior to the  first
     Contract  Anniversary is equal to the Contributions  made for a Participant
     minus any of his  withdrawals.  On each Contract  Anniversary  prior to, or
     concurrent with, the Participant's  date of death, the GMDB is reset, based
     on the age of the Participant on his last birthday, as follows:

     (a)  For  Participants  less than 81 years of age,  the GMDB is the greater
          of:

          (1)  the  Participant's  Account  Value  as of  the  current  Contract
               Anniversary, or

          (2)  (i)  the   GMDB  as  of  the   immediately   preceding   Contract
               Anniversary; increased by

          (ii) any Contributions  made for the Participant since the immediately
               preceding Contract  Anniversary;  and reduced  proportionately to
               reflect

          (iii)any  withdrawals  for  the  Participant   since  the  immediately
               preceding Contract Anniversary.

P-12867.SPIRAGMDB.AMD.1
<PAGE>


     (b)  For Participants 81 years of age or older, the GMDB is equal to:

          (1)  the GMDB as of the immediately  preceding  Contract  Anniversary;
               increased by

          (2)  any Contributions  made for the Participant since the immediately
               preceding Contract  Anniversary;  and reduced  proportionately to
               reflect

          (3)  any  withdrawals  for  the  Participant   since  the  immediately
               preceding Contract Anniversary.

     As of the  Participant's  date of death,  the GMDB  ceases to  increase  or
     decrease in value.

1.13 "Guaranteed Rate of Interest" means interest at an annual effective rate of
     3.00%.

6.3  Administrative  Charge:  AUL deducts an administrative  charge per Contract
     Quarter  equal to the lesser of $7.50 or 0.5% of the  Account  Value on the
     last  day of  each  Contract  Quarter  from  each  Participant  Account  in
     existence on that day for as long as the Participant  Account is in effect.
     This  charge is to be prorated  among each  subaccount  of the  Participant
     Account which  corresponds to each  Investment  Option  utilized under this
     contract  by  that  Participant   Account.  If  the  entire  balance  of  a
     Participant   Account  is  withdrawn   pursuant  to  this   contract,   the
     administrative  charge attributable to the period of time which has elapsed
     since the first day of the  Contract  Quarter  in which the  withdrawal  of
     funds is made is not deducted from the amount withdrawn.

     There is no charge for a Participant for any Contract  Quarter in which the
     Participant's Account Value on the last day of that quarter is greater than
     $25,000.

                     SUMMARY OF CERTAIN CONTRACT PROVISIONS
                                WHICH AFFECT YOU

                                   DEFINITIONS


"Account Value" for any Participant Account on any given date means:

     (a)  the balance of the  Participant  Account's share of the Fixed Interest
          Account on that date; plus

     (b)  the  value  of the  Participant  Account's  share  of each  Investment
          Account on that date.

"Accumulation Period" means the period of time commencing on the date on which a
Participant's  initial  Contribution is credited to the Participant  Account and
terminating on the date when such Participant Account is closed.

"Accumulation  Unit"  means a  statistical  device  used to  measure  amounts of
increases to, decreases from, and accumulations in any Investment Account during
the Accumulation Period.

"Annuity  Commencement  Date"  means the first  day of any month  upon  which an
annuity begins under the Contract. However, for any Participant, this date shall
not be later than the  required  beginning  date as  defined  in the  applicable
sections of the Code and Regulations issued thereunder.

"Code" means the Internal Revenue Code of l986, as amended.

"Contributions"  means  amounts  paid in cash to AUL from time to time by, or on
behalf of, Participants,  which are credited to Participant Accounts.  The legal
title to, and ownership of, such amounts is vested solely in the Participant.

"Current Rates of Interest" means each of the annual effective rates of interest
as  determined  and  declared  by AUL from time to time and as  credited to each
interest pocket maintained within the Fixed Interest Account.  The Current Rates
of Interest  shall  always be equal to or greater  than the  Guaranteed  Rate of
Interest.

"Excess  Contributions"  means those  Contributions  made by, or on behalf of, a
Participant  which exceed the limitations in effect under applicable  provisions
of the Code and Regulations issued thereunder.

"Fixed Interest Account" means that fund of AUL's general asset account in which
all or a portion of a Participant's  Account Value may be held for  accumulation
at the Current Rates of Interest.

     (a)  Contributions allocated, or amounts transferred, to the Fixed Interest
          Account shall be credited to the open  interest  pocket and shall earn
          interest at the Current  Rate of Interest in effect for that  interest
          pocket.  Such  Contributions or transferred  amounts,  during the time
          that the Current  Rate of  Interest  exceeds  the  Guaranteed  Rate of
          Interest,  shall  earn  interest  at  such  credited  Current  Rate of
          Interest for at least 1 year.  After such 1-year period,  AUL reserves
          the right to declare,  at any time,  a new Current Rate of Interest to
          be applied to funds held within  that  interest  pocket.  Any such new
          Current  Rate of  Interest  must  remain in effect  for that  interest
          pocket for at least 1 year.

          Participant in any full contract year.

     (c)  Excess  Contributions  (plus gains or minus losses  thereon)  shall be

          include the amount to be withdrawn  and  returned,  and  certification
          that such Contributions  constitute Excess Contributions and that such
          returns  are  permitted  by  applicable  provisions  of the  Code  and
          Regulations issued  thereunder.  It shall not be the responsibility of

<PAGE>


          Excess Contributions or  gains or losses thereon,  or  that returns of
          Excess  Contributions  are  permitted by applicable  provisions of the
          Code and  Regulations.  In  withdrawing  and  returning the identified
          amount, AUL may rely solely  on such written instructions and certifi-
          cation. Such a withdrawal and return of Excess Contributions shall not
          be subject to the withdrawal benefits provisions of the Contract.

     (d)  Other refunds of  Contributions  shall be applied  before the close of
          the calendar year following the year of such refund toward the payment
          of future contributions or the purchase of additional benefits.

     (e)  When a  Contribution  is  received at AUL's Home  Office,  it shall be
          credited to  Participant  Accounts  as directed in written  allocation
          instructions.

     (f)  The initial  Contribution  for a  Participant  shall be  credited  and
          allocated  to the  Participant  Account  no later  than  the  close of
          business on the second  business day of AUL after the later of (1) the
          business day that AUL receives  the initial  Contribution  at its Home
          Office, or (2) the business day that AUL receives, at its Home Office,
          the data required to establish the Participant  Account and allocation
          instructions regarding the initial Contribution.  If the data required
          to  establish  the  Participant  Account and  allocation  instructions
          regarding the initial Contribution are not received by AUL at its Home
          Office  within 5 business  days after AUL first  receives  the initial
          Contribution,  AUL  shall  return  the  initial  Contribution  to  the
          contributing  party  unless  consent  is  given to AUL to  retain  the
          initial  Contribution  until  AUL  receives  the data  and  allocation
          instructions for the Participant.  Alternatively, if the data required
          to  establish  the  Participant  Account and  allocation  instructions
          regarding the initial Contribution are not received by AUL at its Home
          Office when AUL first receives the initial Contribution, to the extent
          permitted by applicable law, AUL may allocate the initial Contribution
          to the  Money  Market  Investment  Account,  and shall  transfer  such
          amounts credited to the Money Market  Investment  Account according to
          the  applicable  allocation  instructions  upon  receipt  of the  data
          required  to  establish  the   Participant   Account  and   allocation
          instructions.

     (g)  All  Contributions  subsequent  to the initial  Contribution  shall be
          credited and  allocated  as of the close of business on the  Valuation
          Period in which AUL  receives  the  Contribution  at its Home  Office,
          provided that the  Contribution is received by 4:00 p.m. E.S.T. If the
          Contribution  is received after 4:00 p.m.  E.S.T.,  such  Contribution
          shall be deemed to be received, and shall be credited and allocated as
          of the close of business, on the next succeeding Valuation Period.

     (h)  Within any one  Participant  Account,  the amount so credited shall be
          allocated  to an  Investment  Option in  increments  of 10%,  25%,  or
          33-1/3%,  as elected by the  Participant in writing.  If no allocation
          instruction is made with respect to any Participant Account, AUL shall
          process such credits in  accordance  with the  allocation  instruction
          applicable to the immediately preceding Contribution.  If there should
          be no allocation instruction applicable to a portion of a Contribution
          other than the initial Contribution,  that amount shall be credited to
          the  Fixed  Interest   Account  until  such  time  as  an  appropriate
          allocation instruction is received, at which time such amount shall be
          withdrawn  from the Fixed Interest  Account and allocated  pursuant to
          such   instructions.   The   Participant   may  change  an  allocation
          instruction  with  respect to future  allocations  to his  Participant
          Account by giving new written  allocation  instructions  to AUL at its
          Home Office.

          Investment  Account or that the  Variable  Account  or any  Investment

          Accounts if, in its sole  discretion,  marketing,  tax, or  investment
          conditions  so warrant.  AUL also  reserves the right to provide other
          Investment  Options  under the  Contract  at any time.  Subject to any
          required  regulatory  approvals,  AUL  reserves  the right to transfer
          assets from any Investment  Account to another separate account of AUL
          or Investment Account.

     (c)  If deemed by AUL to be in the best  interests  of persons or  entities
          having voting rights under the Contract,  the Variable  Account may be
          operated  as a  management  investment  company  under The  Investment
          Company  Act of 1940 or any other  form  permitted  by law,  it may be
          deregistered  in the event  such  registration  is no longer  required
          under The  Investment  Company Act of 1940, or it may be combined with
          other separate accounts of AUL or an affiliate thereof.

          Accumulation  Period.  For any transfer  from an  Investment  Account,
          Accumulation  Units shall be valued as of the close of business on the
          Valuation Date that AUL receives the Participant's direction, provided
          that AUL receives such direction by 4:00 p.m. E.S.T. on that Valuation
          Date.  If such  direction  is received  after 4:00 p.m.  E.S.T.,  such
          transfer  shall be  effective  as of the close of business on the next
          succeeding Valuation Date.

     (b)  AUL shall make the transfer as requested by the  Participant  within 7
          days from the date a proper  request  is  received  by AUL at its Home
          Office,  except  as AUL may be  permitted  to defer  such  payment  of
          amounts  withdrawn  from  the  Variable  Account  in  accordance  with
          appropriate  provisions of the federal  securities  laws. AUL reserves
          the right to defer a  transfer  of  amounts  from the  Fixed  Interest
          Account  for a period of 6 months  after  AUL  receives  the  transfer
          request at its Home Office.

     (c)  All  transfers  from the  Fixed  Interest  Account  to any  Investment
          Account shall be made on a first-in/first-out  accounting basis.

          Participant Account's share of any Investment Option in an amount less
          than $500 or the  Participant  Account's  entire  share,  if less than
          $500. If such a transfer reduces the Participant  Account's  remaining
          share of an Investment  Option to less than $500, the entire remaining
          share shall also be transferred.

     (e)  Amounts  transferred  from the Fixed  Interest  Account on behalf of a
          Participant  during  any  contract  year  shall not  exceed 20% of the
          Participant  Account's share of the Fixed Interest Account  determined
          as  of  the  last  contract  anniversary  preceding  the  request  for
          transfer,  or the  Participant  Account's  entire  share of the  Fixed
          Interest  Account  if such  share  would be less than  $500  after the
          transfer.

Annuity Options:
- ----------------


At the written request of the  Participant,  AUL shall apply all or a portion of
the  Account  Value  (subject  to any  appropriate  premium  tax  charge) of the
Participant  Account for the purpose of providing a fixed payment annuity.  Upon
receipt of such request,  AUL is hereby  authorized by such Participant to value
and  transfer the  Participant  Account's  share of the Variable  Account to the
Fixed Interest  Account as of the date that AUL receives such written request at
its Home Office.  Such  transferred  amounts shall be held in the Fixed Interest
Account until the  Participant's  Annuity  Commencement  Date.  The  Participant
request  shall include  certification  as to the purpose for the annuity and the
election of one of the following annuity options:


     (a)  Life  Annuity.  The monthly  annuity shall be payable to the annuitant
          for as long as the  annuitant  lives,  and  shall  end  with  the last
          monthly payment before the death of the annuitant.

     (b)  Certain and Life Annuity.  The monthly annuity shall be payable to the
          annuitant for as long as the annuitant  lives.  If the annuitant  dies
          before  receiving  payments  for the certain  period (5, 10, 15, or 20
          years, as specified in the election),  any remaining  payments for the
          balance  of the  certain  period  shall  be  paid  to the  annuitant's
          beneficiary.

     (c)  Survivorship  Annuity.  The  monthly  annuity  shall be payable to the
          annuitant for as long as the annuitant  lives.  After the death of the
          annuitant,  a portion (all, 2/3, or 1/2, as specified in the election)
          of the  annuitant's  monthly  annuity shall be paid to the  contingent
          annuitant  named  in the  election  for  as  long  as  the  contingent
          annuitant lives. An election of this option is automatically cancelled
          if either the Participant or the contingent  annuitant dies before the
          Annuity Commencement Date.

          annuitant for as long as the annuitant  lives,  and shall end with the
          last monthly  payment  before the death of the  annuitant.  If, at the
          death of the  annuitant,  the sum of the monthly  payments  previously
          received  is less than the  amount  applied to  provide  the  annuity,
          monthly  payments of the same amount shall continue to the annuitant's
          beneficiary  until the total of the monthly  payments  received equals
          such amount.

     (e)  Fixed  Period.  The monthly  annuity shall be payable to the annuitant
          for a fixed  period  of time  (not  less than 5 years nor more than 30

          annuitant,  payments  have been made for less than the selected  fixed
          period, monthly annuity payments to the annuitant's  beneficiary shall
          be continued during the remainder of such fixed period.

     (f)  Any other  options  made  available  by AUL at the time a  Participant
          exercises his option to elect an annuity.

or to the  Participant  and the  contingent  annuitant  which would extend for a
certain period beyond the life expectancy of such  Participant or the joint life
expectancy of such  Participant and such  contingent  annuitant as determined on
the Annuity Commencement Date. If an option of periodic payments is elected, any
such payments shall be made at intervals of no longer than one year.

If the total  Account  Value is less than $2,000,  such value shall be paid in a
lump sum to the  annuitant  rather than  annuitized  under the  annuity  options
provided in (a) through (f) above. Additionally,  if the monthly annuity is less
than AUL's then  current  established  minimum,  AUL  reserves the right to make
payments on a less frequent basis.


Death Benefits:
- ---------------


     (a)  Upon   receipt  of  written   instructions   from  the   Participant's
          beneficiary  (or, if  applicable,  the  secondary  beneficiary  of the
          Participant)  and  of  due  proof  of  the   Participant's   (and,  if
          applicable, the beneficiary's) death during the Accumulation Period at
          its Home Office,  AUL shall apply the Account Value of the Participant
          Account  for the  purpose  of  providing  a death  benefit.  The death
          benefit shall be paid to the beneficiary  last properly  designated in
          writing to AUL at its Home Office by the Participant,  or, if there is
          no  designated  beneficiary  living  on the date of the  Participant's
          death, to the  Participant's  estate.  If any  beneficiary  dies while
          receiving  payments and no  beneficiary  is  designated to receive any
          remaining  payments,  such  remaining  payments  shall  be made to the
          deceased beneficiary's estate.

     (b)  The  Account  Value  to be  applied  pursuant  to (a)  above  shall be
          determined  as of the  close  of  business  on the  later  of (1)  the
          Valuation Date that AUL receives such written instructions at its Home
          Office,  or (2) the Valuation Date that AUL receives such due proof of
          death at its Home Office,  provided that such written  instructions or
          due proof of death  received on the later of (1) or (2) above  are(is)
          received by 4:00 p.m. E.S.T. If the written  instructions or due proof
          of death  received on the later of (1) or (2) above  are(is)  received
          after 4:00 p.m.  E.S.T.,  such valuation shall be made as of the close
          of business on the next succeeding Valuation Date.

    (c)  (1)   The  benefit  shall  be  payable  in  accordance  with one of the
               following  provisions  as  elected  by  the  Participant  or  the
               beneficiary if the Participant did not make an election:

               (i)  The entire  Account Value to be applied shall be paid to the
                    beneficiary in a single sum or by another  elected method on
                    or before  December 31 of the calendar  year which  contains
                    the  fifth  anniversary  of the  date  of the  Participant's
                    death; or

<PAGE>

               (ii) The benefit shall be paid as an annuity in  accordance  with
                    the Annuity  Options shown above over a period not to exceed
                    the  life  or life  expectancy  of the  beneficiary.  If the
                    beneficiary is not the Participant's  surviving spouse,  the
                    annuity must begin on or before  December 31 of the calendar
                    year  immediately  following  the calendar year in which the
                    Participant  died. If the  beneficiary is the  Participant's
                    surviving spouse,  such spouse may elect to receive equal or
                    substantially   equal   payments   over  the  life  or  life
                    expectancy  of such spouse  commencing  at any date prior to
                    the  later  of  (1)  December  31  of  the   calendar   year
                    immediately   following  the  calendar  year  in  which  the
                    Participant died, or (2) December 31 of the calendar year in
                    which the  Participant  would have attained age 70 1/2. Such
                    spousal  election  must be made no later than the earlier of
                    December  31 of  the  calendar  year  containing  the  fifth
                    anniversary   of  the   Participant's   death  or  the  date
                    distributions   are  required  to  begin   pursuant  to  the
                    preceding  sentence.  The  surviving  spouse may  accelerate
                    these  payments at any time by  increasing  the frequency or
                    amount of such payments.

          (2)  If a Participant dies on or after his Annuity  Commencement Date,
               any interest remaining under the Annuity Option selected shall be
               paid at least as rapidly as prior to the Participant's death.

          (3)  If  payment  is to be made in a cash lump sum,  payment  shall be
               made within 7 days of the date of valuation, as determined in (b)
               above,  except as AUL may be  permitted  to defer such payment of
               amounts derived from the Variable  Account in accordance with the
               provisions of federal  securities  laws.  Also,  AUL reserves the
               right to defer the  payment of amounts  withdrawn  from the Fixed
               Interest  Account  for a period of 6 months  after  AUL  receives
               written instructions at its Home Office.

Withdrawal Benefits:
- --------------------


     (a)  Except  as stated  below,  a  Participant,  upon  submitting  a proper
          written request to AUL at its Home Office,  may direct AUL to withdraw
          all or a portion  of the  Account  Value  (subject  to the  Withdrawal
          Charge) of his Participant Account.

     (b)  Withdrawals from a Participant Account's share of an Investment Option
          may not be made in an  amount  less  than the  smaller  of $500 or the
          Participant  Account's  entire share of the  Investment  Option.  If a
          withdrawal  reduces the  Participant  Account's share of an Investment
          Option  to  less  than  $500,  such  remaining  share  shall  also  be
          withdrawn.

     (c)  A withdrawal request shall be effective as of the close of business on
          the  Valuation  Date that AUL  receives  a proper  written  withdrawal
          request at its Home Office, provided that AUL receives such request by
          4:00 p.m.  E.S.T.  on that Valuation Date. If such request is received
          after 4:00 p.m.  E.S.T.,  such  request  shall be  effective as of the
          close of business on the next succeeding Valuation Date.

     (d)  The  Account  Value  to be  applied  shall  be  determined  as of  the
          applicable  Valuation  Date  determined  in (c)  above.  If the entire
          Account Value of a Participant  Account is withdrawn,  the Participant
          shall be paid the Withdrawal Value. If the Participant requests that a
          specified percentage or dollar amount be paid to the Participant,  AUL
          shall  withdraw  from the  Participant  Account an amount equal to the
          dollar amount to be paid divided by the  difference  between 1 and the
          decimal    equivalent   of   the   applicable    Withdrawal    Charge.
          Notwithstanding  the  previous
<PAGE>


          sentence, in any contract  year the Participant may withdraw up to 10%
          of  the  Account Value of his Participant Account determined as of the
          last contract  anniversary  preceding  the  request for the withdrawal
          without application of any Withdrawal Charge,  provided that 12 months
          have elapsed from the date that the Participant's  first  Contribution
          is credited to his Participant  Account by AUL to  the  date  of  such
          withdrawal.

     (e)  AUL shall pay such amount in a cash lump sum to the Participant.  Such
          cash  lump sum  will be paid  within  7 days  from  the date  that AUL
          receives the withdrawal request at its Home Office,  except as AUL may
          be  permitted  to defer such  payment of  amounts  withdrawn  from the
          Variable  Account in  accordance  with  appropriate  provisions of the
          federal  securities  laws. AUL reserves the right to defer the payment
          of amounts  withdrawn from the Fixed Interest  Account for a period of
          up to 6 months after AUL receives the  withdrawal  request at its Home
          Office.


     (f)  Withdrawals  from a Participant  Account's share of the Fixed Interest
          Account shall be made on a  first-in/first-out  basis so that all or a
          portion of the amounts credited to the Participant  Account's share of
          the Fixed  Interest  Account  (other than amounts which are prohibited
          from being  distributed  because  provision  (a)(1)  above is not met)
          which have been on deposit for the longest  period of time, as well as
          the interest credited thereon, shall be withdrawn first.


                                   VALUATIONS

All assets of each  Portfolio  shall be valued as provided in the prospectus for
the Mutual Fund as such prospectus may be amended or  supplemented  from time to
time.

Any  amounts  that are  allocated  to any  Investment  Account  on  behalf  of a
Participant  shall  be  credited  to his  Participant  Account  in the  form  of
Accumulation  Units on the basis of the value of such  units in that  Investment
Account as of the end of the Valuation Period on which such amounts are received
by AUL at its Home Office.  Such crediting  shall be made separately for amounts
allocated to each Investment  Account.  The number of Accumulation Units in each
Investment  Account  credited to each  Participant  Account as of any  Valuation
Period shall be determined by dividing the amounts  allocated to that Investment
Account for that  Participant  Account as of such Valuation Period by the dollar
value of one  Accumulation  Unit in that  Investment  Account as of the close of
business on the applicable  Valuation Period.  The number of Accumulation  Units
thus  determined  shall not be  changed by any  subsequent  change in the dollar
value of the Accumulation Units.

The value of an Accumulation Unit in each Investment  Account was established at
$1.00 as of April 12, 1990. The value of an Accumulation Unit in each Investment
Account as of any  Valuation  Period  thereafter is equal to the dollar value of
one Accumulation Unit in that Investment Account as of the immediately preceding
Valuation Period multiplied by the Net Investment  Factor, as defined below, for
that  Investment  Account  for the  current  Valuation  Period.  The value of an
Accumulation  Unit for each  Investment  Account  shall be  determined  for each
Valuation  Period  before  giving  effect  to  any  additions,  withdrawals,  or
transfers. After such determination,  the additions,  withdrawals,  or transfers
which are effective as of that day shall then be made.

The Net Investment  Factor for each Investment  Account for any Valuation Period
is determined by dividing (a) by (b), and then subtracting (c) from that result,
where:

     (a)  is equal to:

          (1)  the net asset value of a Portfolio  share held in the  Investment
               Account determined as of the end of the current Valuation Period,
               plus
<PAGE>

          (2)  the per share  amount of any dividend or other  distribution,  if
               any, paid by the Portfolio during the current  Valuation  Period,
               plus or minus

          (3)  any credit or charge for any taxes  paid or  reserved  for by AUL
               during the current  Valuation  Period which are determined by AUL
               to be attributable to operation of the Investment Account;


     (b)  is the net asset  value of a  Portfolio  share held in the  Investment
          Account  determined  as  of  the  end  of  the  immediately  preceding
          Valuation Period; and

     (c)  is a daily  charge  factor  determined  by AUL to reflect  the charges
          assessed  against the assets of the  Investment  Account for mortality
          and expense risks.

The value of each  Participant  Account's share of any Investment  Account as of
any Valuation Date shall be determined by multiplying the Participant  Account's
aggregate  Accumulation  Units in that  Investment  Account as of such Valuation
Date by the dollar value of one Accumulation Unit in that Investment  Account as
of such Valuation  Date.  The value of the  Participant  Account's  share of any
Investment  Account as of any date other than a  Valuation  Date is equal to the
value of its share of that Investment  Account as of the  immediately  preceding
Valuation Date.

                                  OTHER CHARGES


AUL shall deduct a daily  mortality  risk charge and a daily expense risk charge
equal to the daily  equivalent of an annual combined charge of 1.25% against the
average daily net assets of each Investment Account.

The Mutual Fund shall pay an investment advisory fee and certain other expenses,
which may include its operational and organizational  expenses,  as described in
the current  prospectus as it may be amended or supplemented  from time to time.
These expenses may vary from year to year. The net asset value of each Portfolio
reflects such investment advisory fee and other expenses which are deducted from
the assets of such Portfolio.

AUL shall deduct an administrative charge per Contract year quarter equal to the
lesser  of $7.50  or 0.5% of the  Account  Value  on the  last day of each  such
quarter  from each  Participant  Account in existence on such day for so long as
the Participant Account is in effect during the Accumulation Period. This charge
(not to exceed $100 per  contract  year  quarter)  is to be prorated  among each
subaccount of the  Participant  Account  which  corresponds  to each  Investment
Option utilized under the Contract by that Participant Account.

AUL reserves the right to deduct a charge (not to exceed $25) for each  transfer
transaction,  to deduct the  appropriate  premium tax  charge,  or to deduct the
appropriate  charges for federal,  state,  or local income taxes incurred by AUL
that are attributable to the Variable Account and its Investment Accounts.

                    RIGHT OF AUL TO CHANGE CERTAIN PROVISIONS

AUL reserves the right to amend the Contract at any time, without the consent of
the  Contractholder,  Participants,  or any other person or entity,  to make any

The value of each  Participant  Account's share of any Investment  Account as of
any Valuation Date shall be determined by multiplying the Participant  Account's
aggregate  Accumulation  Units in that  Investment  Account as of such Valuation
Date by the dollar value of one Accumulation Unit in that Investment  Account as
of such Valuation  Date.  The value of the  Participant  Account's  share of any

Tax Status:  AUL does not make any guarantee  regarding the federal,  state,  or
local  tax  status  of  the  Contract,   any  Participant   Account  established
thereunder, or any transaction involving the Contract.

Essential  Data: The  Participant  shall furnish to AUL whatever  information is
necessary to establish the eligibility and amount of annuity or other benefit in
each instance.

Reliance:  AUL shall be fully protected in relying on any information  furnished
by  the  Contractholder,  by  any  person  or  persons  certified  to AUL by the
Contractholder  as  acting  on its  behalf,  or by a  Participant.  AUL need not
inquire as to the accuracy or completeness thereof.

Misstatement  of Essential  Data: If it has been found that any  essential  data
pertaining  to any person  has been  omitted or  misstated,  including,  but not
limited  to, a  misstatement  as to the age of an  annuitant,  there shall be an
equitable  adjustment  so as to provide  the  annuity  to which  that  person is
entitled.  If this misstatement is revealed after periodic annuity payments have
begun, any  underpayment  will immediately be disbursed by AUL to the annuitant.
Any overpayments will be deducted from subsequent  payments,  until AUL recovers
the overpayment.

Annuity  Certificates:  AUL shall  issue to each  person  for whom an annuity is
purchased  from AUL a certificate  setting forth the amount and terms of payment
of the annuity.

Election, Notice, or Direction Requirements:  Wherever in the Contract reference
is made to the  Contractholder or Participant  making a request or giving notice
or direction,  such request, notice, or direction must be in writing and must be
submitted to, and received by, AUL at its Home Office before becoming effective,
unless the Participant is otherwise directed by AUL.

Quarterly  Statement of Account Value: As soon as reasonably  possible after the
end of each contract year quarter,  AUL shall prepare a statement of the Account
Value of each Participant Account existing under the Contract.

Sex and Number: Whenever the context of this Certificate so requires, the plural
includes the singular, the singular the plural, and the masculine the feminine.

Facility of Payment: If any Participant, contingent annuitant, or beneficiary is
legally  incapable  of giving a valid  receipt for any  payment due him,  and no
guardian has been appointed,  AUL may make such payment to the person or persons
who have assumed the care and principal support of such Participant,  contingent
annuitant, or beneficiary.  Also, AUL may make payment directly to any person or
entity when directed to do so in writing by the Participant. Any payment made by
AUL will fully discharge AUL to the extent of such payment.

Insulation from Liability: The assets of the Variable Account are not chargeable
with liabilities arising out of any other business AUL may conduct.

Voting:
- -------


(a)  AUL is the  legal  owner  of the  shares  of the  Mutual  Fund  held by the
     Investment  Accounts of the Variable  Account.  AUL shall  exercise  voting
     rights  attributable to the shares of each Portfolio held in the Investment
     Accounts at any regular and  special  meetings of the  shareholders  of the
     Mutual Fund on matters  requiring  shareholder  voting under The Investment
     Company Act of l940

<PAGE>


     or other applicable laws.  AUL shall exercise  these voting rights based on
     instructions   received  from  persons   having  the  voting   interest  in
     corresponding Investment Accounts of the Variable Account.  However, if The
     Investment  Company  Act of l940 or any  regulations  thereunder  should be
     amended, or if the present  interpretation  thereof should change, and as a
     result AUL determines that it is permitted to vote the shares of the Mutual
     Fund in its own right,  it may elect to do so. AUL will vote  shares of any
     Investment   Account,  if  any,  that  it  owns  beneficially  in  its  own
     discretion,  except  that if the  Mutual  Fund  offers  its  shares  to any
     insurance  company  separate  account that funds  variable  life  insurance
     contracts or if otherwise required by applicable law, AUL will vote its own
     shares in the same proportion as the voting  instructions that are received
     in a timely manner for contracts and Participant Accounts  participating in
     the Investment Account.

(b)  The  persons  having  the  voting  interest  under  the  Contract  are  the
     Participants.

(c)  Voting  rights  attributable  to the  Contract  for which no timely  voting
     instructions  are received  will be voted by AUL in the same  proportion as
     the  voting  instructions  which are  received  in a timely  manner for all
     contracts  and  Participant  Accounts   participating  in  that  Investment
     Account.

(d)  Neither the Variable Account nor AUL is under any duty to inquire as to the
     instructions received or the authority of Contractholders, Participants, or
     others to instruct the voting of Mutual Fund shares.

(e)  Every person or entity having such voting rights shall receive such reports
     or prospectuses  concerning the Variable  Account or the Mutual Fund as may
     be required by applicable federal law.

Nonforfeitability  and  Nontransferability:  The  entire  Withdrawal  Value of a
Participant  Account under the Contract shall be nonforfeitable at all times. No
sum  payable  under the  Contract  with  respect to a  Participant  may be sold,
assigned, discounted, or pledged as collateral for a loan or as security for the
performance  of an  obligation  or for any other purpose to any person or entity
other than AUL. In addition,  to the extent  permitted by law, no such sum shall
in any way be  subject  to legal  process  requiring  the  payment  of any claim
against the payee.


Acceptance  of  Contributions:  AUL  shall  have the  right to  refuse to accept
Contributions  as of the last day of the second  month  following  the date that
written notice to this effect is delivered to any contributing Participant or to
any Participant for whom Contributions are being made.

The Effective Date of this Addendum is the effective  date of the  corresponding

Pursuant to this Addendum,  the Participant's  Certificate under the Contract is

AUL shall deduct a daily  mortality  risk charge and a daily expense risk charge
equal to the daily  equivalent of an annual combined charge of 1.25% against the
average daily net assets of each  Investment  Account.  Additionally,  AUL shall
multiply the portions (as delineated in the table below) of the total  month-end
Account Value in the Variable Account of all Participants in the contract by the
monthly equivalent of the corresponding  Annual Variable Investment Plus Factors

The Effective Date of this Addendum is the effective  date of the  corresponding
Amendment to the Contract.

Pursuant to this Addendum,  the Participant's  Certificate under the Contract is
hereby amended as follows:

By adding the following to the face page of the Certificate:

                          The Contract is a SIMPLE IRA.

By deleting the definition of "Contributions"  in the Participant's  Certificate
under the Contract and by substituting the following definition in lieu thereof:


                                   DEFINITIONS

"Contributions"  means,  subject to the restrictions of the following paragraph,
amounts  paid  in  cash  to AUL  from  time  to time  by,  or on  behalf  of,  a
Participant,  including amounts  transferred to the Contract from another SIMPLE
IRA of the Participant, which are credited to his Participant Account maintained
under the Contract. The legal title to, and ownership of, such amounts is vested
solely in the Participant. The Contract is established for the exclusive benefit
of the Participant or his beneficiaries.

The  SIMPLE  IRA will  accept  only  cash  Contributions  made on  behalf of the
Participant  pursuant  to the terms of a SIMPLE  IRA Plan  described  in section
408(p) of the Internal  Revenue Code. A rollover  Contribution  or a transfer of
assets from another  SIMPLE IRA of the  Participant  will also be  accepted.  No
other Contributions will be accepted.

By  deleting  item (b) as it appears  under the heading  indicated  below in the
Participant's  Certificate  under the Contract and by substituting the following
item (b) in lieu thereof,  and by adding the  following  items (i) and (g) under
the headings indicated below:


                    CONTRIBUTIONS, INVESTMENTS AND TRANSFERS

Contributions:
- --------------

(b)  Except for amounts  rolled over or  transferred  from another SIMPLE IRA of
     the Participant,  Contributions during a Participant's  taxable year (which
     is  presumed to be a calendar  year) may not exceed the amounts  allowed by
     Code Section 408(p) (as adjusted).

     (i)  If  Contributions  made on behalf  of the  Participant  pursuant  to a
          SIMPLE IRA Plan maintained by the Participant's  employer are received
          directly by AUL from the employer,  AUL will provide the employer with
          the summary description  required by section 408(1)(2) of the Internal
          Revenue Code.

                                    BENEFITS

Withdrawal Benefits:

(g)  Prior to the  expiration  of the 2-year  period  beginning  on the date the
     Participant  first  participated  in any SIMPLE IRA Plan  maintained by the
     Participant's  employer,  any  rollover or transfer by the  Participant  of
     funds  from  the  SIMPLE  IRA  must be made to  another  SIMPLE  IRA of the
     Participant.  Any  distribution  of funds to the  Participant  during  this
     2-year  period  may  be  subject  to a  25-percent  additional  tax  if the
     Participant  does not roll over the amount  distributed  into a SIMPLE IRA.
     After the expiration of this 2-year period,  the  Participant may roll over
     or transfer  funds to any IRA of the  Participant  that is qualified  under
     section 408(a) or (b) of the Internal Revenue Code.

   The Effective Date of this Amendment is the date that it is signed by AUL.

     reserves  the  right  to  eliminate  the  shares  of any  of  the  eligible
     Portfolios and to substitute  shares of, or interests in, another Portfolio
     of the AUL American  Series Fund,  Inc.,  of another  open-end,  registered
     investment  company,  or  other  investment  vehicle,  for  shares  already
     purchased  or to be  purchased  in the future  under the  Contract,  if the
     shares  of any or all  eligible  Portfolios  are no  longer  available  for
     investment,  or if, in AUL's  judgment,  further  investment  in any or all
     eligible  Portfolios  becomes  inappropriate in view of the purposes of the
     Variable Account or the contract.  Where required under applicable law, AUL
     will not  substitute  any shares in the Variable  Account or any Investment
     Account  without  notice,  Participant  approval,  or prior approval of the
     Securities and Exchange Commission or a state insurance  commissioner,  and
     without following the filing or other procedures  established by applicable
     state  insurance  regulators.  Nothing  contained  herein shall prevent the
     Variable  Account  from  purchasing  other  securities  for other series or
     classes of  contracts,  or from  effecting a conversion  between  series or
     classes  of  contracts  on the  basis of  requests  made by a  majority  of
     participants or as permitted by federal law.

(b)  AUL reserves the right to establish additional Investment Accounts, each of
     which would invest in the corresponding Mutual Fund Portfolio listed in the
     current  prospectus  for the Variable  Account,  or in other  securities or
     investment  vehicles.  AUL  reserves  the  right to  eliminate  or  combine
     existing Investment Accounts if, in its sole discretion, marketing, tax, or
     investment  conditions  so warrant.  AUL also reserves the right to provide
     other  Investment  Options  under the Contract at any time.  Subject to any
     required  regulatory  approvals,  AUL reserves the right to transfer assets
     from  any  Investment  Account  to  another  separate  account  of  AUL  or
     Investment Account.

(c)  In the event of any such  substitution  or change,  AUL may, by appropriate
     amendment,  make  such  changes  in the  Contract  as may be  necessary  or
     appropriate to reflect such  substitution or change. If deemed by AUL to be
     in the best interests of persons or entities having voting rights under the
     Contract,  the Variable Account may be operated as a management  investment
     company  under  The  Investment  Company  Act of  1940  or any  other  form
     permitted by law, it may be deregistered in the event such  registration is
     no longer  required under The Investment  Company Act of 1940, or it may be
     combined with other separate accounts of AUL or an affiliate  thereof.  AUL
     may take  such  action  as is  necessary  to  comply  with,  or to  obtain,
     exemptions  from the Securities and Exchange  Commission with regard to the
     Variable  Account.  Subject to compliance with applicable law, AUL also may
     combine one or more  Investment  Accounts  and may  establish a  committee,
     board, or other group to manage one or more aspects of the operation of the
     Variable Account.

Withdrawal Benefits:
- --------------------


(d)  The Account Value to be applied  shall be  determined as of the  applicable
     Valuation  Date  determined in (c) above.  If the entire Account Value of a
     Participant  Account  is  withdrawn,  the  Participant  shall  be paid  the
     Withdrawal Value. If the Participant  requests that a specified  percentage
     or dollar amount be paid to the  Participant,  AUL shall  withdraw from the
     Participant Account an amount equal to the dollar amount to be paid divided
     by the  difference  between 1 and the decimal  equivalent of the applicable
     Withdrawal  Charge.  Notwithstanding  the previous  sentence,  in the first
     Contract year in which a  Participant  Account is  established,  and in the
     next  succeeding  Contract  year,  the  Participant  may withdraw from that
     Participant  Account  up to 10% of the  sum of the  Account  Value  of that
     Participant  Account,  determined  as  of  the  last  Contract  anniversary
     preceding the request for the withdrawal,  plus  Contributions  made during
     the applicable Contract year, without application of any Withdrawal Charge.
     In any subsequent  Contract year,  the  Participant  may withdraw from that
     Participant  Account  up to 10% of the  Account  Value of that  Participant
     Account,  determined  as of the last  Contract  anniversary  preceding  the
     request for the withdrawal, without application of any Withdrawal Charge.

                                   VALUATIONS

All assets of each  Portfolio  shall be valued as provided in the prospectus for
the applicable  Mutual Fund as such  prospectus  may be amended or  supplemented
from time to time.

Any  amounts  that are  allocated  to any  Investment  Account  on  behalf  of a
Participant  shall  be  credited  to his  Participant  Account  in the  form  of
Accumulation  Units on the basis of the value of such  units in that  Investment
Account as of the end of the Valuation Period on which such amounts are received
by AUL at its Home Office.  Such crediting  shall be made separately for amounts
allocated to each Investment  Account.  The number of Accumulation Units in each
Investment  Account  credited to each  Participant  Account as of any  Valuation
Period shall be determined by dividing the amounts allocated to that
<PAGE>


Investment  Account for that Participant  Account as of such Valuation Period by
the dollar value of one Accumulation  Unit in that Investment  Account as of the
close of business on the applicable Valuation Period. The number of Accumulation
Units  thus  determined  shall not be changed  by any  subsequent  change in the
dollar value of the Accumulation Units.

The  value of an  Accumulation  Unit in the AUL  American  Equity,  Bond,  Money
Market, and Managed Investment Accounts was established at $1.00 as of April 12,
1990.  The  value  of an  Accumulation  Unit  in any  other  Investment  Account
available under the Contract shall be established at $1.00 as of the date of the
first deposit to such Investment  Account.  The value of an Accumulation Unit in
each Investment  Account as of any Valuation  Period  thereafter is equal to the
dollar  value of one  Accumulation  Unit in that  Investment  Account  as of the
immediately  preceding Valuation Period multiplied by the Net Investment Factor,
as defined below, for that Investment  Account for the current Valuation Period.
The  value  of an  Accumulation  Unit  for  each  Investment  Account  shall  be
determined  for each  Valuation  Period before  giving effect to any  additions,
withdrawals, or transfers. After such determination, the additions, withdrawals,
or transfers which are effective as of that day shall then be made.

The Net Investment  Factor for each Investment  Account for any Valuation Period
is determined by dividing (a) by (b), and then subtracting (c) from that result,
where:

(a)  is equal to:

     (1)  the net  asset  value  of a  Portfolio  share  held in the  Investment
          Account determined as of the end of the current Valuation Period, plus

     (2)  the per share  amount of any dividend or other  distribution,  if any,
          paid by the Portfolio  during the current  Valuation  Period,  plus or
          minus

     (3)  any credit or charge for any taxes paid or reserved  for by AUL during
          the  current  Valuation  Period  which  are  determined  by  AUL to be
          attributable to operation of the Investment Account;

(b)  is the net asset value of a Portfolio share held in the Investment  Account
     determined as of the end of the immediately preceding Valuation Period; and

(c)  is a daily charge factor  determined by AUL to reflect the charges assessed
     against  the assets of the  Investment  Account for  mortality  and expense
     risks, as authorized under "Other Charges" below.

The value of each  Participant  Account's share of any Investment  Account as of
any Valuation Date shall be determined by multiplying the Participant  Account's
aggregate  Accumulation  Units in that  Investment  Account as of such Valuation
Date by the dollar value of one Accumulation Unit in that Investment  Account as
of such Valuation  Date.  The value of the  Participant  Account's  share of any
Investment  Account as of any date other than a  Valuation  Date is equal to the
value of its share of that Investment  Account as of the  immediately  preceding
Valuation Date.
                                  OTHER CHARGES

AUL shall deduct a daily  mortality  risk charge and a daily expense risk charge
equal to the daily  equivalent of an annual combined charge of 1.25% against the
average  daily net assets of each  Investment  Account.  These  charges shall be
reflected in the Net Investment Factor as defined above.



P-12868.ADD.2
<PAGE>


A Mutual Fund shall pay any investment  advisory fee and certain other expenses,
which may include its operational and organizational  expenses,  as described in
the current prospectus for that Mutual Fund as it may be amended or supplemented
from time to time.  These  expenses  may vary  from year to year.  The net asset
value of each Portfolio reflects such investment advisory fee and other expenses
which are deducted from the assets of such Portfolio.

AUL shall deduct an administrative charge per Contract year quarter equal to the
lesser  of $7.50  or 0.5% of the  Account  Value  on the  last day of each  such
quarter  from each  Participant  Account in existence on such day for so long as
the Participant Account is in effect during the Accumulation Period. This charge
is to be  prorated  among  each  subaccount  of the  Participant  Account  which
corresponds  to each  Investment  Option  utilized  under the  Contract  by that
Participant Account.

AUL  reserves  the right to deduct a charge for each  transfer  transaction,  to
deduct the appropriate  premium tax charge, or to deduct the appropriate charges
for federal,  state, or local income taxes incurred by AUL that are attributable
to the Variable Account and its Investment Accounts.

Voting:
- -------


(a)  AUL is  the  legal  owner  of the  shares  of a  Mutual  Fund  held  by the
     Investment  Accounts of the Variable  Account.  AUL shall  exercise  voting
     rights  attributable to the shares of each Portfolio held in the Investment
     Accounts  at any regular and  special  meetings  of the  shareholders  of a
     Mutual Fund on matters  requiring  shareholder  voting under The Investment
     Company Act of l940 or other  applicable  laws.  AUL shall  exercise  these
     voting rights based on instructions received from persons having the voting
     interest in  corresponding  Investment  Accounts of the  Variable  Account.
     However,  if  The  Investment  Company  Act  of  l940  or  any  regulations
     thereunder  should be  amended,  or if the present  interpretation  thereof
     should change,  and as a result AUL determines that it is permitted to vote
     the shares of a Mutual  Fund in its own  right,  it may elect to do so. AUL
     will  vote  shares  of  any  Investment  Account,  if  any,  that  it  owns
     beneficially in its own discretion, except that if a Mutual Fund offers its
     shares to any insurance  company  separate account that funds variable life
     insurance  contracts or if otherwise  required by applicable  law, AUL will
     vote its own shares in the same proportion as the voting  instructions that
     are received in a timely  manner for  contracts  and  Participant  Accounts
     participating in the Investment Account.

(b)  The  persons  having  the  voting  interest  under  the  Contract  are  the
     Participants.  Unless  otherwise  required by applicable law, the number of
     Mutual  Fund  shares  of  a   particular   Portfolio  as  to  which  voting
     instructions may be given to AUL is determined by dividing the value of all
     of  the  Accumulation   Units  of  the  corresponding   Investment  Account
     attributable  to this contract on a particular  date by the net asset value
     per share of that Portfolio as of the same date.  Fractional  votes will be
     counted.  The number of votes as to which voting  instructions may be given
     will be determined as of the date coincident  with the date  established by
     the applicable Mutual Fund for determining shareholders eligible to vote at
     the meeting of that Mutual Fund. If required by the Securities and Exchange
     Commission,  AUL reserves the right to determine in a different fashion the
     voting rights attributable to the shares of a Mutual Fund.

(c)  Voting  rights  attributable  to the  Contract  for which no timely  voting
     instructions  are received  will be voted by AUL in the same  proportion as
     the  voting  instructions  which are  received  in a timely  manner for all
     contracts  and  Participant  Accounts   participating  in  that  Investment
     Account.

(d)  Neither the Variable Account nor AUL is under any duty to inquire as to the
     instructions received or the authority of Contractholders, Participants, or
     others to instruct the voting of Mutual Fund shares.

(e)  Every person or entity having such voting rights shall receive such reports
     or prospectuses  concerning the Variable Account or a Mutual Fund as may be
     required by applicable federal law.

                                     TO THE

                                    ISSUED BY
                  AMERICAN UNITED LIFE INSURANCE COMPANY (AUL)
                                       TO
            BANK ONE AS CUSTODIAN ON BEHALF OF ANY PERSON ELIGIBLE TO
           PARTICIPATE IN AN IRA 408 INDIVIDUAL RETIREMENT ANNUITY WHO
          BECOMES A PARTICIPANT UNDER THIS CONTRACT AND SUCH SUCCESSOR
              CUSTODIAN AS MAY BE APPOINTED FROM TIME TO TIME (THE
                                CONTRACTHOLDER)

                           EFFECTIVE DATE: MAY 1, 1993

AUL and the Contractholder  hereby agree, by signing below, that the Contract is
hereby  amended by deleting the  corresponding  Sections and  Subsections of the
Contract,  if any, and by inserting the following  Sections and  Subsections  in
lieu thereof:

     1.12  "Fixed  Interest  Account"  means  that fund of AUL's  general  asset
account in which all or a portion of a  Participant's  Account Value may be held
for accumulation at the Current Rates of Interest.

     (a)  Contributions  allocated,  or amounts transferred (excluding transfers
          discussed  in (c)  below),  to the  Fixed  Interest  Account  shall be
          credited to the open  interest  pocket and shall earn  interest at the
          Current  Rate of Interest  in effect for that  interest  pocket.  Such
          Contributions or transferred amounts, during the time that the Current
          Rate of Interest  exceeds the Guaranteed Rate of Interest,  shall earn
          interest at such  credited  Current  Rate of  Interest  for at least 1
          year. After such 1-year period, AUL reserves the right to declare,  at
          any time,  a new Current  Rate of Interest to be applied to funds held
          within that  interest  pocket.  Any such new Current  Rate of Interest
          must remain in effect for that interest pocket for at least 1 year.

     (b)  If AUL changes the Current Rate of Interest for such new Contributions
          or new amounts transferred to the Fixed Interest Account, the previous
          open  interest  pocket  shall  close,  and any such  Contributions  or
          amounts  transferred  on or after the  effective  date of such  change
          shall be  credited  to a new  open  interest  pocket  and  shall  earn
          interest  at the new  Current  Rate of Interest in effect for such new
          open  interest  pocket.  Therefore,  at any given time,  various funds
          credited to a Participant  Account and allocated to the Fixed Interest
          Account may be earning interest at different Current Rates of Interest
          for different periods of time.

     (c)  Any contribution to another AUL P-12867 contract which is allocated to
          the Fixed  Interest  Account and which is transferred to this contract
          (plus  gains and minus  losses  thereon)  and  allocated  to the Fixed
          Interest Account,  beginning with the date of such transfer,  shall be
          credited with the

P-12867.OI.AMD

<PAGE>

          Current Rate  of Interest under  this  contract which was in effect on
          the  date the transferred contribution  was originally  deposited into
          the Fixed Interest Account under the previous AUL contract.

     1.15  "Investment  Account" means each  subaccount of the Variable  Account
made available to the  Contractholder by AUL and identified in Schedule A of the
contract.  Schedule A of the contract may be amended by AUL from time to time as
described in Section 3.3. Amounts allocated to any Investment Account identified
in  Schedule  A of  the  contract  shall  be  invested  in  the  shares  of  the
corresponding  Mutual Fund  Portfolio  listed in the current  prospectus for the
Variable Account.

P-12867.OI.AMD

<PAGE>


     1.17 "Mutual Fund" means the AUL American Series Fund, Inc., a diversified,
open-end  management investment  company registered under The Investment Company
Act of l940,  and any other such  open-end  management  investment  company made
available by AUL.

     1.20 "Portfolio" means a series of a particular Mutual Fund as described in
that  prospectus  for that Mutual  Fund,  as such  prospectus  may be amended or
supplemented from time to time.

     1.24 "Withdrawal  Charge" means a charge taken by AUL equal to a percentage
of the Account Value of a Participant Account withdrawn pursuant to Section 4.8,
where the  percentage  varies by the number of full years measured from the date
that Participant Account is established,  or from the date a Participant Account
is  established  under a previous AUL P-12867  contract  from which amounts have
been transferred to this Participant  Account, to the date the Withdrawal Charge
is determined. Such percentage is as follows:


                                During
                           Account Years                      Percentage

                                1                               6
                                2                               5
                                3                               4
                                4                               3
                                5                               2
                                6                               1
                           Thereafter                           0

In no event will the cumulative total of all Withdrawal Charges, including those
previously  assessed  against any amount  withdrawn from a Participant  Account,
exceed 9% of total Contributions allocated to that Participant Account.

     3.1 Amount of Contributions:

     (a)  Contributions  may vary in amount and  frequency;  however,  a minimum
          Contribution  of at least  $100,000 must be made for a Participant  in
          order to establish a Participant Account. Any additional Contributions
          made  within the  12-month  period  beginning  on the date the initial
          Contribution  is credited  to that  Participant  Account  (hereinafter
          called a Certificate  Year) shall also be credited to that Participant
          Account. Any initial Contribution made within a different  Certificate
          Year shall also be subject

P-12867.OI.AMD.1
<PAGE>

          to the $100,000  minimum, and  any  Contributions   made  within  that
          Certificate Year shall be allocated to a separate  Participant Account
          and  shall  be  evidenced  by a  separate  certificate  issued  to the
          Participant.  AUL may change the minimum Contribution acceptable under
          this contract, but any such change shall apply only to individuals who
          become  Participants on or after the date of the change. This contract
          will not terminate  solely because a Contribution  is not made for any
          Contract Year.


     3.3 Addition, Deletion, or Substitution of Investments:


     (a)  AUL reserves the right,  subject to compliance with applicable law, to
          make additions to, deletions from,  substitution  for, or combinations
          of,  the  securities  that are  held by the  Variable  Account  or any
          Investment  Account or that the  Variable  Account  or any  Investment
          Account may  purchase.  AUL reserves the right to eliminate the shares
          of any of the  eligible  Portfolios  and to  substitute  shares of, or
          interests  in,  another  Portfolio of the  AUL  American  Series Fund,
          Inc., of another open-end,  registered  investment  company,  or other
          investment vehicle, for shares already purchased or to be purchased in
          the future  under the  contract,  if the shares of any or all eligible
          Portfolios  are no longer  available for  investment,  or if, in AUL's
          judgment, further investment in any or all eligible Portfolios becomes
          inappropriate  in view of the purposes of the Variable  Account or the
          contract.  Where required under applicable law, AUL will no substitute
          any shares in the Variable  Account or any Investment  Account without
          notice, Participant approval, or prior approval of the Securities and
          Exchange  Commission or a state  insurance  commissioner,  and without
          following  the filing or other  procedures  established  by applicable
          state insurance regulators. Nothing contained herein shall prevent the
          Variable  Account from purchasing other securities for other series or
          classes of contracts, or from effecting a conversion between series or
          classes of  contracts  on the basis of requests  made by a majority of
          participants or as permitted by federal law.

     (b)  AUL reserves the right to establish  additional  Investment  Accounts,
          each of which would invest in the corresponding  Mutual Fund Portfolio
          listed in the current prospectus for the Variable Account, or in other
          securities or investment vehicles. AUL reserves the right to eliminate
          or combine  existing  Investment  Accounts if, in its sole discretion,
          marketing, tax, or investment conditions so warrant. AUL also reserves
          the right to provide other  Investment  Options under this contract at
          any time. Subject to any required regulatory  approvals,  AUL reserves
          the right to transfer  assets from any

<PAGE>


          Investment Account to another separate  account of AUL  or  Investment
          Account.

     (c)  In the  event  of  any  such  substitution  or  change,  AUL  may,  by
          appropriate  amendment,  make such changes in this  contract as may be
          necessary or appropriate to reflect such  substitution  or change.  If
          deemed  by AUL to  be in the best  interests  of  persons  or entities
          having voting rights under this contract,  the Variable Account may be
          operated  as a  management  investment  company  under The  Investment
          Company  Act of 1940 or any other  form  permitted  by law,  it may be
          deregistered  in the event  such  registration  is no longer  required
          under The  Investment  Company Act of 1940, or it may be combined with
          other separate accounts of AUL or an affiliate  thereof.  AUL may take
          such action as is necessary to comply with,  or to obtain,  exemptions
          from  the  Securities  and  Exchange  Commission  with  regard  to the
          Variable Account.  Subject to compliance with applicable law, AUL also
          may  combine  one or more  Investment  Accounts  and may  establish  a
          committee,  board, or other group to manage one or more aspects of the
          operation of the Variable Account.


     4.8 Withdrawal Benefits:

     (d)  The  Account  Value to be applied  pursuant to this  Section  shall be
          determined  as of the  applicable  Valuation  Date  determined  in (c)
          above.  If the  entire  Account  Value  of a  Participant  Account  is
          withdrawn,  the Participant shall be paid the Withdrawal Value. If the
          Participant  requests that a specified  percentage or dollar amount be
          paid to the  Participant,  AUL  shall  withdraw  from the  Participant
          Account an amount equal to the dollar amount to be paid divided by the
          difference  between 1 and the  decimal  equivalent  of the  applicable
          Withdrawal Charge. Notwithstanding the previous sentence, in the first
          Contract Year in which a Participant  Account is  established,  and in
          the next  succeeding  Contract Year, the Participant may withdraw from
          that Participant  Account up to 10% of the sum of the Account Value of
          that  Participant   Account,   determined  as  of  the  last  Contract
          Anniversary   preceding   the   request  for  the   withdrawal,   plus
          Contributions  made  during  the  applicable  Contract  Year,  without
          application of any Withdrawal Charge. In any subsequent Contract Year,
          the Participant may withdraw from that  Participant  Account up to 10%
          of the Account Value of that Participant Account, determined as of the
          last Contract  Anniversary  preceding the request for the  withdrawal,
          without application of any Withdrawal Charge.  Where amounts have been
          transferred  to this  contract  from  another  AUL  P-12867  contract,
          Contract  Years of  participation  for  purposes of this 10%  free-out
          provision  shall be determined by using the date of the  Participant's
          first contribution to the Participant Account in the previous contract
          which was transferred.

     5.1 Time of  Valuation:  All  assets of each  Portfolio  shall be valued as
provided in the prospectus for the applicable Mutual Fund as such prospectus may
be amended or supplemented from time to time.

     5.3 Value of Accumulation  Units: The value of an Accumulation  Unit in the
AUL American Equity,  Bond, Money Market,  and Managed  Investment  Accounts was
established at $1.00 as of April 12, 1990. The value of an Accumulation  Unit in
any other Investment Account avail able under this contract shall be established
at $1.00 as of the date of the first  deposit to such  Investment  Account.  The
value of an  Accumulation  Unit in each  Investment  Account as of any Valuation
Period  thereafter is equal to the dollar value of one Accumulation Unit in that
Investment Account as of the immediately  preceding  Valuation Period multiplied
by the Net  Investment  Factor,  as defined in Section 5.4, for that  Investment
Account for the current Valuation Period. The  value of an Accumulation Unit for
each  Investment  Account shall be deter mined for each Valuation  Period before
giving   effect  to  any  additions,  withdrawals,  or  transfers.  After   such
determination,  the additions,  withdrawals, or transfers which are effective as
of that day shall then be made.


     5.4 Determining the Net Investment  Factor:  The Net Investment  Factor for
each Investment  Account for any Valuation  Period is determined by dividing (a)
by (b), and then subtracting (c) from that result, where:

     (a)  is equal to:

          (1)  the net asset value of a Portfolio  share held in the  Investment
               Account determined as of the end of the current Valuation Period,
               plus

          (2)  the per share  amount of any dividend or other  distribution,  if
               any, paid by the Portfolio during the current  Valuation  Period,
               plus or minus

          (3)  any credit or charge for  any taxes paid or  reserved  for by AUL
               during the current  Valuation  Period which are determined by AUL
               to be attributable to operation of the Investment Account;

     (b)  is the net asset  value of a  Portfolio  share held in the  Investment
          Account  deter  mined  as of  the  end of  the  immediately  preceding
          Valuation Period; and

     (c)  is a daily  charge  factor  determined  by AUL to reflect  the charges
          assessed  against the assets of the  Investment  Account for mortality
          and expense risks, as authorized by Section 6.1.

P-12867.OI.AMD.2
<PAGE>

     6.1  Mortality  Risk and Expense  Risk  Charges:  AUL shall  deduct a daily
mortality  risk  charge  and a daily  expense  risk  charge  equal to the  daily
equivalent of an annual  combined  charge of 1.25% against the average daily net
assets of each Investment  Account.  These charges shall be reflected in the Net
Investment Factor as provided in Section 5.4(c).

     6.2 Investment  Management  Charge:  A Mutual Fund shall pay any investment
advisory fee and certain other  expenses,  which may include its operational and
organizational expenses, as described  in the current prospectus for that Mutual
Fund as it may be amended or supplemented  from time to time. These expenses may
vary from year to year.  The net asset  value of each  Portfolio  reflects  such
investment advisory fee and other expenses which are deducted from the assets of
such Portfolio.

By deleting the first sentence of Section 6.3 and by substituting  the following
first sentence in lieu thereof:

     6.3 Administrative  Charge:  AUL shall deduct an administrative  charge per
Contract  Quarter  equal to the lesser of $0.00 or 0.5% of the Account  Value on
the last day of each Contract Quarter from each Participant Account in existence
on such day for as long as the  Participant  Account  is in  effect  during  the
Accumulation Period.

     6.6  Reduction  or Waiver of Certain  Charges:  AUL may reduce or waive the
amount of  the Withdrawal  Charge  or the  administrative  charge  discussed  in
Section 6.3 where the expenses associated  with the sale of this contract or the
administrative  costs  associated with this contract are reduced,  or where this
contract is sold to the directors or employees of AUL or any of  its affiliates,
or to directors or any  employees of the AUL American  Series Fund,  Inc. or any
other Mutual Fund made available by AUL.

     8.15 Voting:

     (a)  AUL is the  legal  owner of the  shares  of a Mutual  Fund held by the
          Investment Accounts of the Variable Account. AUL shall exercise voting
          rights  attributable  to the  shares  of  each  Portfolio  held in the
          Investment  Accounts  at  any  regular  and  special  meetings  of the
          shareholders of a Mutual Fund on matters requiring  shareholder voting
          under The Investment Company Act of l940 or other applicable laws. AUL
          shall exercise  these  voting  rights based on  instructions  received
          from persons having the voting  interest in  corresponding  Investment
          Accounts of the Variable Account.  However,  if The Investment Company
          Act of l940 or any  regulations  thereunder  should  be amended, or if
          the present  interpretation thereof should change, and as a result AUL
          deter mines that it is  permitted  to vote the shares of a Mutual Fund
          in its own right,  it may elect to do so. AUL will vote  shares of any
          Investment  Account,  if any,  that it  owns  beneficially  in its own
          discretion,  except  that if a Mutual  Fund  offers  its shares to any
          insurance  company separate account that funds variable life insurance
          contracts or if otherwise  required by  applicable  law, AUL will vote
          its own shares in the same  proportion as the voting instructions that
          are received in a timely manner for contracts and Participant Accounts
          participating  in the Investment  Account.


     (b)  The persons  having the voting  interest  under this  contract are the
          Participants.  Unless otherwise required by applicable law, the number
          of Mutual Fund shares of a  particular  Portfolio  as to which  voting
          instructions  may be given to AUL is determined  by dividing the value
          of all of  the  Accumulation  Units  of the  corresponding  Investment
          Account  attributable to this contract on a particular date by the net
          asset  value  per  share  of  that  Portfolio  as of  the  same  date.
          Fractional  votes  will be  counted.  The  number of votes as to which
          voting  instructions  may be given will be  determined  as of the date
          coincident with  the date  established by the  applicable  Mutual Fund
          for determining  shareholders eligible  to vote at the meeting of that
          Mutual Fund. If required by the  Securities  and Exchange  Commission,
          AUL reserves the right to determine in a different  fashion the voting
          rights attributable to the shares of a Mutual Fund.


     (c)  Voting rights attributable to this contract for which no timely voting
          instructions  are received will be voted by AUL in the same proportion
          as the voting  instructions  which are received in a timely manner for
          all  contracts  and  Participant   Accounts   participating   in  that
          Investment Account.

     (d)  Neither the  Variable  Account nor AUL is under any duty to inquire as
          to the instructions  received  or  the  authority of  Contractholders,
          Participants, or others to instruct the voting of Mutual Fund shares.

     (e)  Every person or entity  having such voting  rights shall  receive such
          reports or prospectuses  concerning the  Variable  Account or a Mutual
          Fund as may be required by applicable federal law.

          The Effective Date of this Amendment is ____________________.

AUL and the Contractholder  hereby agree, by signing below, that the Contract is
hereby amended as follows:

By adding the following to the face page of the Contract:

                         This contract is a SIMPLE IRA.

By deleting Section 1.9 and by substituting the following in lieu thereof:

     1.9  "Contributions"  means,  subject to the  restrictions of the following
paragraph,  amounts paid in cash to AUL from time to time by, or on behalf of, a
Participant,  including amounts transferred to this contract from another SIMPLE
IRA of the Participant, which are credited to his Participant Account maintained
hereunder.  The legal title to, and  ownership of, such amounts is vested solely
in the Participant. The contract is established for the exclusive benefit of the
Participant or his beneficiaries.

This  SIMPLE  IRA will  accept  only  cash  Contributions  made on behalf of the
Participant  pursuant  to the terms of a SIMPLE  IRA Plan  described  in section
408(p) of the Internal  Revenue Code. A rollover  Contribution  or a transfer of
assets from another  SIMPLE IRA of the  Participant  will also be  accepted.  No
other Contributions will be accepted.

By deleting  Subsection  3.1(b) and by  substituting  the  following  Subsection
3.1(b) in lieu thereof, and by adding the following Subsection 3.1(e):

   3.1    (b)  Except for  amounts  rolled  over  or  transferred  from  another
               SIMPLE   IRA  of  the   Participant,   Contributions   during   a
               Participant's  taxable  year  (which is presumed to be a calendar
               year) may not exceed the amounts  allowed by Code Section  408(p)
               (as adjusted).

          (e)  If Contributions made on behalf of the Participant  pursuant to a
               SIMPLE IRA Plan  maintained  by the  Participant's  employer  are
               received directly by AUL from the employer,  AUL will provide the
               employer  with  the  summary  description   required  by  section
               408(1)(2) of the Internal Revenue Code.

By adding the following Subsection 4.8(g):

   4.8    (g)  Prior  to  the expiration of  the 2-year period  beginning on the
               date the  Participant  first  participated in any SIMPLE IRA Plan
               maintained  by  the  Participant's   employer,  any  rollover  or
               transfer by the Participant of funds from this SIMPLE IRA must be
               made to another SIMPLE IRA of the  Participant.  Any distribution
               of funds to the  Participant  during  this  2-year  period may be
               subject to a 25-percent  additional tax if the  Participant  does
               not roll over the amount distributed into a SIMPLE IRA. After the
               expiration of this 2-year period,  the  Participant may roll over
               or transfer funds to any IRA of the Participant that is qualified
               under section 408(a) or (b) of the Internal Revenue Code.

                        ABC COMPANY (THE CONTRACTHOLDER)

   The Effective Date of this Amendment is the date that it is signed by AUL.

AUL and the Contractholder  hereby agree, by signing below, that the Contract is
hereby  amended by deleting the  corresponding  Sections and  Subsections of the
Contract,  if any, and by inserting the following  Sections and  Subsections  in
lieu thereof:

     1.15  "Investment  Account" means each  subaccount of the Variable  Account
made available to the  Contractholder by AUL and identified in Schedule A of the
contract.  Schedule A of the contract may be amended by AUL from time to time as
described in Section 3.3. Amounts allocated to any Investment Account identified
in  Schedule  A of  the  contract  shall  be  invested  in  the  shares  of  the
corresponding  Mutual Fund  Portfolio  listed in the current  prospectus for the
Variable Account.

     1.17 "Mutual Fund" means the AUL American Series Fund, Inc., a diversified,
open-end  management  investment company registered under The Investment Company
Act of l940,  and any other such  open-end  management  investment  company made
available by AUL.

     1.20 "Portfolio" means a series of a particular Mutual Fund as described in
that  prospectus  for that Mutual  Fund,  as such  prospectus  may be amended or
supplemented from time to time.

     3.3 Addition, Deletion, or Substitution of Investments:

     (a)  AUL reserves the right,  subject to compliance with applicable law, to
          make additions to, deletions from,  substitution  for, or combinations
          of,  the  securities  that are  held by the  Variable  Account  or any
          Investment  Account or that the  Variable  Account  or any  Investment
          Account may  purchase.  AUL reserves the right to eliminate the shares
          of any of the  eligible  Portfolios  and to  substitute  shares of, or
          interests in, another Portfolio of the AUL American Series Fund, Inc.,
          of  another  open-end,   registered   investment   company,  or  other
          investment vehicle, for shares already purchased or to be purchased in
          the future  under the  contract,  if the shares of any or all eligible
          Portfolios  are no longer  available for  investment,  or if, in AUL's
          judgment, further investment in any or all eligible Portfolios becomes
          inappropriate  in view of the purposes of the Variable  Account or the
          contract. Where required under applicable law, AUL will not substitute
          any shares in the Variable  Account or any Investment  Account without
          notice,  Participant approval, or prior approval of the Securities and
          Exchange  Commission or a state  insurance  commissioner,  and without
          following  the filing or other  procedures  established  by applicable
          state insurance regulators. Nothing contained herein shall prevent the
          Variable  Account from purchasing other securities for other series or
          classes of contracts, or from effecting a conversion between series or
          classes of  contracts  on the basis of requests  made by a majority of
          participants  or as  permitted  by federal  law.  (b) AUL reserves the
          right to establish additional Investment Accounts, each of which would
          invest  in the  corresponding  Mutual  Fund  Portfolio  listed  in the
          current prospectus for the


P-12867.AMD1

                                       1
<PAGE>

          Variable Account, or in other securities  or  investment vehicles. AUL
          reserves  the  right  to  eliminate  or  combine  existing  Investment
          Accounts if, in its sole  discretion,  marketing,  tax, or  investment
          conditions  so warrant.  AUL also  reserves the right to provide other
          Investment  Options  under this  contract at any time.  Subject to any
          required  regulatory  approvals,  AUL  reserves  the right to transfer
          assets from any Investment  Account to another separate account of AUL
          or Investment Account.

     (c)  In the  event  of  any  such  substitution  or  change,  AUL  may,  by
          appropriate  amendment,  make such changes in this  contract as may be
          necessary or appropriate to reflect such  substitution  or change.  If
          deemed  by AUL to be in the best  interests  of  persons  or  entities
          having voting rights under this contract,  the Variable Account may be
          operated  as a  management  investment  company  under The  Investment
          Company  Act of 1940 or any other  form  permitted  by law,  it may be
          deregistered  in the event  such  registration  is no longer  required
          under The  Investment  Company Act of 1940, or it may be combined with
          other separate accounts of AUL or an affiliate  thereof.  AUL may take
          such action as is necessary to comply with,  or to obtain,  exemptions
          from  the  Securities  and  Exchange  Commission  with  regard  to the
          Variable Account.  Subject to compliance with applicable law, AUL also
          may  combine  one or more  Investment  Accounts  and may  establish  a
          committee,  board, or other group to manage one or more aspects of the
          operation of the Variable Account.

     4.8 Withdrawal Benefits:

     (d)  The  Account  Value to be applied  pursuant to this  Section  shall be
          determined  as of the  applicable  Valuation  Date  determined  in (c)
          above.  If the  entire  Account  Value  of a  Participant  Account  is
          withdrawn,  the Participant shall be paid the Withdrawal Value. If the
          Participant  requests that a specified  percentage or dollar amount be
          paid to the  Participant,  AUL  shall  withdraw  from the  Participant
          Account an amount equal to the dollar amount to be paid divided by the
          difference  between 1 and the  decimal  equivalent  of the  applicable
          Withdrawal Charge. Notwithstanding the previous sentence, in the first
          Contract Year in which a Participant  Account is  established,  and in
          the next  succeeding  Contract Year, the Participant may withdraw from
          that Participant  Account up to 10% of the sum of the Account Value of
          that  Participant   Account,   determined  as  of  the  last  Contract
          Anniversary   preceding   the   request  for  the   withdrawal,   plus
          Contributions  made  during  the  applicable  Contract  Year,  without
          application of any Withdrawal Charge. In any subsequent Contract Year,
          the Participant may withdraw from that  Participant  Account up to 10%
          of the Account Value of that Participant Account, determined as of the
          last Contract  Anniversary  preceding the request for the  withdrawal,
          without application of any Withdrawal Charge.

     5.1 Time of  Valuation:  All  assets of each  Portfolio  shall be valued as
provided in the prospectus for the applicable Mutual Fund as such prospectus may
be amended or supplemented from time to time.

     5.3 Value of Accumulation  Units: The value of an Accumulation  Unit in the
AUL American Equity,  Bond, Money Market,  and Managed  Investment  Accounts was
established at $1.00 as of April 12, 1990. The value of an Accumulation  Unit in
any other Investment  Account available under this contract shall be established
at $1.00 as of the date of the first  deposit to such  Investment  Account.  The
value of an  Accumulation  Unit in each  Investment  Account as of any Valuation
Period  thereafter is equal to the dollar value of one Accumulation Unit in that
Investment Account as of the immediately  preceding  Valuation Period multiplied
by the Net Investment Factor, as defined



P-12867.AMD2


                                       2
<PAGE>

in Section 5.4, for that Investment  Account for the current  Valuation  Period.
The  value  of an  Accumulation  Unit  for  each  Investment  Account  shall  be
determined  for each  Valuation  Period before  giving effect to any  additions,
withdrawals, or transfers. After such determination, the additions, withdrawals,
or transfers which are effective as of that day shall then be made.

     5.4 Determining the Net Investment  Factor:  The Net Investment  Factor for
each Investment  Account for any Valuation  Period is determined by dividing (a)
by (b), and then subtracting (c) from that result, where:

     (a)  is equal to:

          (1)  the net asset value of a Portfolio  share held in the  Investment
               Account determined as of the end of the current Valuation Period,
               plus

          (2)  the per share  amount of any dividend or other  distribution,  if
               any, paid by the Portfolio during the current  Valuation  Period,
               plus or minus

          (3)  any credit or charge for any taxes  paid or  reserved  for by AUL
               during the current  Valuation  Period which are determined by AUL
               to be attributable to operation of the Investment Account;

     (b)  is the net asset  value of a  Portfolio  share held in the  Investment
          Account  determined  as  of  the  end  of  the  immediately  preceding
          Valuation Period; and

     (c)  is a daily  charge  factor  determined  by AUL to reflect  the charges
          assessed  against the assets of the  Investment  Account for mortality
          and expense risks, as authorized by Section 6.1.

     6.1  Mortality  Risk and Expense  Risk  Charges:  AUL shall  deduct a daily
mortality  risk  charge  and a daily  expense  risk  charge  equal to the  daily
equivalent of an annual  combined  charge of 1.25% against the average daily net
assets of each Investment  Account.  These charges shall be reflected in the Net
Investment Factor as provided in Section 5.4(c).

     6.2 Investment  Management  Charge:  A Mutual Fund shall pay any investment
advisory fee and certain other  expenses,  which may include its operational and
organizational  expenses, as described in the current prospectus for that Mutual
Fund as it may be amended or supplemented  from time to time. These expenses may
vary from year to year.  The net asset  value of each  Portfolio  reflects  such
investment advisory fee and other expenses which are deducted from the assets of
such Portfolio.

     6.6  Reduction  or Waiver of Certain  Charges:  AUL may reduce or waive the
amount of  the  Withdrawal  Charge or the  administrative  charge  discussed  in
Section 6.3 where the expenses  associated with the sale of this contract or the
administrative  costs  associated with this contract are reduced,  or where this
contract is sold to the directors or employees of AUL or any of its  affiliates,
or to directors or any  employees of the AUL American  Series Fund,  Inc. or any
other Mutual Fund made available by AUL.

     8.15 Voting:

     (a)  AUL is the  legal  owner of the  shares  of a Mutual  Fund held by the
          Investment Accounts of the Variable Account. AUL shall exercise voting
          rights  attributable  to the  shares  of  each  Portfolio  held in the
          Investment  Accounts  at  any  regular  and  special  meetings  of the
          shareholders of a Mutual Fund on matters requiring  shareholder voting
          under The Investment Company Act of l940 or other applicable laws. AUL
          shall exercise these voting rights based on instructions received from
          persons  having  the  voting  interest  in  corresponding   Investment
          Accounts of the Variable Account.  However,  if The Investment Company
          Act of l940 or any regulations thereunder should be amended, or if the
          present  interpretation  thereof  should  change,  and as a result AUL
          determines that it is permitted to vote the shares of a Mutual Fund in
          its own  right,  it may elect to do so.  AUL will  vote  shares of any
          Investment  Account,  if any,  that it  owns  beneficially  in its own
          discretion,  except  that if a Mutual  Fund  offers  its shares to any
          insurance  company separate account that funds variable life insurance
          contracts or if otherwise  required by  applicable  law, AUL will vote
          its own shares in the same proportion as the voting  instructions that
          are received in a timely manner for contracts and Participant Accounts
          participating in the Investment Account.

     (b)  The persons  having the voting  interest  under this  contract are the
          Participants.  Unless otherwise required by applicable law, the number
          of Mutual Fund shares of a  particular  Portfolio  as to which  voting
          instructions  may be given to AUL is  determined by dividing the value
          of all of  the  Accumulation  Units  of the  corresponding  Investment
          Account  attributable to this contract on a particular date by the net
          asset  value  per  share  of  that  Portfolio  as of  the  same  date.
          Fractional  votes  will be  counted.  The  number of votes as to which
          voting  instructions  may be given will be  determined  as of the date
          coincident with the date established by the applicable Mutual Fund for
          determining  shareholders  eligible  to  vote at the  meeting  of that
          Mutual Fund. If required by the  Securities  and Exchange  Commission,
          AUL reserves the right to determine in a different  fashion the voting
          rights attributable to the shares of a Mutual Fund.

     (c)  Voting rights attributable to this contract for which no timely voting
          instructions  are received will be voted by AUL in the same proportion
          as the voting  instructions  which are received in a timely manner for
          all  contracts  and  Participant   Accounts   participating   in  that
          Investment Account.

     (d)  Neither the  Variable  Account nor AUL is under any duty to inquire as
          to the  instructions  received or the  authority  of  Contractholders,
          Participants, or others to instruct the voting of Mutual Fund shares.

     (e)  Every person or entity  having such voting  rights shall  receive such
          reports or prospectuses  concerning the  Variable  Account or a Mutual
          Fund as may be required by applicable federal law.

                             PARTICIPANT CERTIFICATE
                                  ISSUED UNDER

PEOPLES BANK & TRUST  COMPANY AS  CUSTODIAN ON BEHALF OF ANY PERSON  ELIGIBLE TO
PARTICIPATE  IN  AN  IRC  408  INDIVIDUAL   RETIREMENT  ANNUITY  WHO  BECOMES  A
PARTICIPANT UNDER THIS CONTRACT AND SUCH SUCCESSOR CUSTODIAN AS MAY BE APPOINTED
FROM TIME TO TIME (THE CONTRACTHOLDER)

The Participant's Certificate is hereby amended as follows:

By deleting the term "death benefit"  wherever it appears in the Certificate and
by substituting "Death Benefit" in lieu thereof.

And by deleting the corresponding Sections or Subsections of the Certificate and
by substituting the following Sections or Subsections in lieu thereof:

"Death Benefit" means the greater of:

     (a)  the  Participant's  Account  Value as of the date the Death Benefit is
          calculated, or

     (b)  (1) the  Guaranteed  Minimum  Death  Benefit  (GMDB)  on the  Contract
          Anniversary immediately preceding the date of the Participant's death;
          increased by

          (2)  any  Contributions  made  for  the  Participant  since  the  last
               Contract Anniversary; and reduced proportionately to reflect

          (3)  any  withdrawals  for the  Participant  since  the last  Contract
               Anniversary.

"Guaranteed  Minimum  Death  Benefit"  or  "GMDB"  prior to the  first  Contract
Anniversary  means the  Contributions  made for a  Participant  minus any of his
withdrawals.  On each Contract  Anniversary  prior to, or concurrent  with,  the
Participant's  date  of  death,  the  GMDB  is  reset,  based  on the age of the
Participant on his last birthday, as follows:

     (a)  For  Participants  less than 81 years of age,  the GMDB is the greater
          of:

          (1)  the  Participant's  Account  Value  as of  the  current  Contract
               Anniversary, or

          (2)  (i)  the   GMDB  as  of  the   immediately   preceding   Contract
               Anniversary; increased by

               (ii) any  Contributions   made  for  the  Participant  since  the
                    immediately  preceding  Contract  Anniversary;  and  reduced
                    proportionately to reflect

               (iii)any withdrawals  for the  Participant  since the immediately
                    preceding Contract Anniversary.

     (b)  For Participants 81 years of age or older, the GMDB is equal to:

P-12868.NOLOADIRAGMDB.ADD.1
<PAGE>

          (1)  the GMDB as of the immediately  preceding  Contract  Anniversary;
               increased by

          (2)  any Contributions  made for the Participant since the immediately
               preceding Contract  Anniversary;  and reduced  proportionately to
               reflect

          (3)  any  withdrawals  for  the  Participant   since  the  immediately
               preceding Contract Anniversary.

As of the  Participant's  date of death, the GMDB ceases to increase or decrease
in value.

"Guaranteed  Rate of Interest"  means  interest at an annual  effective  rate of
3.00%.

                                  OTHER CHARGES

AUL deducts an administrative charge per Contract Quarter equal to the lesser of
$7.50 or 0.5% of the Account Value on the last day of each Contract Quarter from
each Participant Account in existence on that day for as long as the Participant
Account is in effect. This charge is to be prorated among each subaccount of the
Participant  Account which  corresponds to each Investment Option utilized under
the contract by that Participant Account. If the entire balance of a Participant
Account  is  withdrawn  pursuant  to the  contract,  the  administrative  charge
attributable  to the period of time which has elapsed since the first day of the
Contract  Quarter in which the  withdrawal of funds is made is not deducted from
the amount withdrawn.

There is no charge  for a  Participant  for any  Contract  Quarter  in which the
Participant's  Account  Value on the last day of that  quarter is  greater  than
$25,000.

(b)  (1) the Guaranteed Minimum Death Benefit (GMDB) on the Contract Anniversary
     immediately preceding the date of the Participant's death; increased by

     (2)  any  Contributions  made for the  Participant  since the last Contract
          Anniversary; and reduced proportionately to reflect

     (3)  any  withdrawals   for  the   Participant   since  the  last  Contract
          Anniversary.

"Guaranteed  Minimum  Death  Benefit"  or  "GMDB"  prior to the  first  Contract
Anniversary  means the  Contributions  made for a  Participant  minus any of his
withdrawals.  On each Contract  Anniversary  prior to, or concurrent  with,  the
Participant's  date  of  death,  the  GMDB  is  reset,  based  on the age of the
Participant on his last birthday, as follows:

(a)  For Participants less than 81 years of age, the GMDB is the greater of:

     (1)  the   Participant's   Account   Value  as  of  the  current   Contract
          Anniversary, or

     (2)  (i) the GMDB as of the  immediately  preceding  Contract  Anniversary;
          increased by

          (ii) any Contributions  made for the Participant since the immediately
               preceding Contract  Anniversary;  and reduced  proportionately to
               reflect

     (iii)any withdrawals for the  Participant  since the immediately  preceding
          Contract Anniversary.

(b)  For Participants 81 years of age or older, the GMDB is equal to:

P-12868.SPIRAGMDB.ADD.1
<PAGE>


     (1)  the  GMDB  as  of  the  immediately  preceding  Contract  Anniversary;
          increased by

     (2)  any  Contributions  made for the  Participant  since  the  immediately
          preceding Contract Anniversary; and reduced proportionately to reflect

     (3)  any withdrawals for the  Participant  since the immediately  preceding
          Contract Anniversary.

As of the  Participant's  date of death, the GMDB ceases to increase or decrease
in value.

"Guaranteed  Rate of Interest"  means  interest at an annual  effective  rate of
3.00%.

                                  OTHER CHARGES

AUL deducts an administrative charge per Contract Quarter equal to the lesser of
$7.50 or 0.5% of the Account Value on the last day of each Contract Quarter from
each Participant Account in existence on that day for as long as the Participant
Account is in effect. This charge is to be prorated among each subaccount of the
Participant  Account which  corresponds to each Investment Option utilized under
the contract by that Participant Account. If the entire balance of a Participant
Account  is  withdrawn  pursuant  to the  contract,  the  administrative  charge
attributable  to the period of time which has elapsed since the first day of the
Contract  Quarter in which the  withdrawal of funds is made is not deducted from
the amount withdrawn.

There is no charge  for a  Participant  for any  Contract  Quarter  in which the
Participant's  Account  Value on the last day of that  quarter is  greater  than
$25,000.

                             SECTION 1 - DEFINITIONS

1.1  "Account Value" for a Participant Account as of a date is:

     (a)  that  account's  balance in the Fixed  Interest  Account (FIA) on that
          date; plus

     (b)  the  value of that  account's  Accumulation  Units in each  Investment
          Account on that date.

1.2  "Accumulation  Unit" is a valuation device used to measure increases in and
     decreases to the value of any Investment Account.

1.3  "Annuity Commencement Date" is the first day of the month an annuity begins
     under  this  contract.  This  date  may  not  be  later  than  the  date  a
     Participant's periodic benefits are required to commence under the Code.

1.4  "Business  Day" is any day both the New York  Stock  Exchange  and our Home
     Office are open for the general conduct of business.

1.5  "Code"  means  the  Internal  Revenue  Code of 1986,  as  amended,  and any
     applicable regulations or rulings thereunder.

1.6  The  "First  Contract  Anniversary"  is listed on the  contract  face page.
     Subsequent "Contract  Anniversaries" are on the same day of each subsequent
     year.

1.7  "Contract Quarter" is each of the four successive  three-month periods in a
     Contract Year.

1.8  The first  "Contract  Year" starts on the Contract Date and ends on the day
     before the First Contract Anniversary. Each subsequent Contract Year starts
     on a Contract  Anniversary  and ends on the day  before  the next  Contract
     Anniversary.

1.9  "Contributions"  are amounts paid to us,  which we credit to a  Participant
     Account.  Contributions  include amounts transferred from another AUL group
     annuity contract.  Contributions include "Elective Deferrals," which means,
     with  respect to any taxable  year,  any  Contribution  made under a salary
     reduction agreement. A Contribution made under a salary reduction agreement
     is not  treated as an  Elective  Deferral  if,  under the salary  reduction
     agreement,  the  Contribution  is made  pursuant to a one-time  irrevocable
     election  made by the  Participant  at the time of initial  eligibility  to
     participate in the agreement,  or is made pursuant to a similar arrangement
     involving a one-time  irrevocable  election specified in Regulations issued
     under the Code.

1.10 "Death Benefit" is the greater of:

     (a)  the  Participant's  Account  Value as of the date the Death Benefit is
          calculated, or

     (b)  (1) the  Guaranteed  Minimum  Death  Benefit  (GMDB)  on the  Contract
              Anniversary  immediately  preceding  the date of the Participant's
              death; increased by

          (2) any   Contributions  made  for  the  Participant  since  the  last
              Contract Anniversary; and reduced proportionately to reflect

          (3) any   withdrawals  for the  Participant  since  the last  Contract
              Anniversary.


P-K-TDAMFVA-GMDB(BR).3
<PAGE>

1.11 "Excess  Contributions"  are Contributions in excess of the applicable Code
     limits.

1.12 "Fixed  Interest  Account"  or "FIA" is the  portion of our  general  asset
     account as described in Section 3, to which  Contributions may be allocated
     for accumulation at the Guaranteed Rates.

1.13 The  "Guaranteed  Minimum  Death  Benefit"  or  "GMDB"  prior to the  first
     Contract  Anniversary is equal to the Contributions  made for a Participant
     minus any of his withdrawals or loans. On each Contract  Anniversary  prior
     to, or concurrent with, the Participant's date of death, the GMDB is reset,
     based on the age of the Participant on his last birthday, as follows:

     (a)  For  Participants  less than 81 years of age,  the GMDB is the greater
          of:

          (1)  the  Participant's  Account  Value  as of  the  current  Contract
               Anniversary, or

          (2)  (i)  the   GMDB  as  of  the   immediately   preceding   Contract
                    Anniversary; increased by

               (ii) any  Contributions   made  for  the  Participant  since  the
                    immediately  preceding  Contract  Anniversary;  and  reduced
                    proportionately to reflect

               (iii)any withdrawals  for the  Participant  since the immediately
                    preceding Contract Anniversary.

     (b)  For Participants 81 years of age or older, the GMDB is equal to:

          (1)  the GMDB as of the immediately  preceding  Contract  Anniversary;
               increased by

          (2)  any Contributions  made for the Participant since the immediately
               preceding Contract  Anniversary;  and reduced  proportionately to
               reflect

          (3)  any  withdrawals  for  the  Participant   since  the  immediately
               preceding Contract Anniversary.

     As of the  Participant's  date of death,  the GMDB  ceases to  increase  or
     decrease in value.

1.14 "Guaranteed Rates" are the guaranteed annual effective rates of interest we
     credit to each Interest  Pocket.  A Guaranteed Rate may be modified only as
     described in Section 3.2.

1.15 "Home  Office"  is our  principal  office  in  Indianapolis,  Indiana.  For
     anything to be "received by AUL," it must be received at our Home Office.

1.16 "Interest  Pocket" means a tracking method which associates funds deposited
     into the FIA over a specific time period with a specific  Guaranteed  Rate,
     as described in Section 3. After the guaranteed  period provided in Section
     3.2 has  elapsed,  we may  consolidate  two or  more  Interest  Pockets  in
     conjunction with the announcement of new Guaranteed Rates.

1.17 "Investment  Account" means each distinct portfolio  established within our
     Variable Account and identified in the Table of Investment Accounts in this
     contract.  Amounts allocated to any Investment  Account are invested in the
     shares of the  corresponding  Mutual Fund or  Portfolio  identified  in the
     Table of Investment Accounts.  Our "Variable Account" is a separate account
     we maintain  under  Indiana law which is called the AUL American Unit Trust
     and which is registered under the Investment  Company Act of 1940 as a unit
     investment trust.


P-K-TDAMFVA-GMDB(BR).4
<PAGE>

1.18 "Investment  Option" is the FIA or any Investment  Account.  We reserve the
     right to provide other Investment Options under this contract at any time.

1.19 "Mutual  Fund"  means  any  diversified,  open-end,  management  investment
     company  made  available  by us,  and  listed  in the  Table of  Investment
     Accounts.

1.20 "Participant" is any person that has a Participant Account.

1.21 "Participant   Account"  is  an  account   under  this  contract  for  each
     Participant.   We  credit   Contributions   to  Participant   Accounts  and
     Contribution-type subaccounts as you direct.

1.22 "Portfolio" is a portfolio  established within a particular Mutual Fund, as
     described in the Mutual Fund's current prospectus.

1.23 "Valuation  Periods" start at the close of each Business Day and end at the
     close of the next Business Day.

1.24 The  "Withdrawal  Charge" is a percentage  of the Account  Value  withdrawn
     under this contract. The Withdrawal Charge will not apply to Account Values
     withdrawn  to  provide a benefit  payment or an  annuity  as  described  in
     Sections  5.2  and  7.1,   respectively.   The  percentage  varies  by  the
     Participant  Account  Year in  which  the  withdrawal  is made.  The  first
     Participant Account Year begins on the date when we establish a Participant
     Account and credit the initial  Contribution for the Participant,  and ends
     on the day  immediately  preceding the next  anniversary of such date. Each
     Participant  Account Year thereafter begins on such an anniversary date and
     ends on the day immediately preceding the next succeeding anniversary date.
     The Withdrawal Charge percentage is as follows:

           During                              Withdrawal Charge
    Participant Account Years                      Percentage

            1                                           7%
            2                                           6%
            3                                           5%
            4                                           4%
            5                                           3%
            6                                           2%
            7                                           1%
       Thereafter                                       0%

     In no event will the cumulative total of all Withdrawal Charges,  including
     those  previously  assessed against any amount withdrawn from a Participant
     Account,  exceed 8.5% of total Contributions  allocated to that Participant
     Account.

1.25 "Withdrawal  Value" is a Participant's  Account Value, minus any Withdrawal
     Charge, outstanding loan balance, and expense charges due on such loans.

               SECTION 2 - ADMINISTRATION OF PARTICIPANT ACCOUNTS

2.1  How Contributions Are Handled: Contributions we receive are credited to the
     appropriate  Contribution-type  subaccounts of each Participant Account, as
     you  direct  in  your  allocation  instructions.  A  Participant's  initial
     Contribution is allocated to the Participant Account by the second Business
     Day after we (1) receive the initial Contribution or, if later, (2) receive
     all data necessary to complete the allocation  (including  data required to
     establish  the  Participant   Account,  the  amount  of  the  Participant's
     Contribution,  and Investment Option elections.)  Subsequent  Contributions
     are allocated to the Participant Account on the Business Day we (1) receive
     that  Contribution or, if later, (2) receive all data necessary to complete
     the allocation.

     If we do not receive the data required to establish a  Participant  Account
     and the amount of a Contribution for the Participant within 5 Business Days
     after we first receive that Contribution,  we will return that Contribution
     to you  unless you  consent to us  retaining  that  Contribution  until the
     earlier of (i) the date we receive such data and amount and, therefore, can
     properly allocate that  Contribution to the Participant  Account or (ii) 25
     days from the date we receive that Contribution.

     If we receive the data required to establish a Participant  Account and the
     amount  of a  Contribution  for  the  Participant,  but we do  not  receive
     Investment  Option  elections for that  Participant,  the  Contribution  is
     allocated to the AUL  American  Money Market  Investment  Account.  When we
     receive  all  required  data,  amounts  in the AUL  American  Money  Market
     Investment  Account,  plus gains and minus losses,  are  transferred to the
     appropriate Investment Option for each designated Contribution-type.

     Participant  Accounts  may  be  allocated  to  Investment  Options  in  any
     increments  acceptable to us.  Investment Option elections remain in effect
     until  changed by you. A change in Investment  Option  elections is made by
     giving us new Investment Option elections.

2.2  Transfers from Other Retirement Programs: We may accept amounts transferred
     from other Code Section 403(b) funding vehicles.  Such transferred amounts,
     as  identified  by you,  are credited to a rollover  subaccount,  under the
     appropriate Participant Account.

2.3  Excess   Contributions:   On  receipt  of  instructions  from  you  or  the
     Participant,  we will withdraw Excess  Contributions,  plus gains and minus
     losses, from a Participant  Account and return them to the Participant,  or
     as you direct.  Such  instructions must state the amount to be returned and
     certify  that such  Contributions  are Excess  Contributions  and that such
     return is  permitted  by the Code.  A return  of  Excess  Contributions  is
     treated like a benefit payment under Section 5.2.

     No Participant is permitted to have Elective Deferral contributions (within
     the meaning of Code Section  402(g)(3))  made during a calendar  year under
     this  contract,  or under  any  other  plans,  contracts,  or  arrangements
     maintained  by his employer,  in excess of the dollar  limitation in effect
     under Code Section  402(g)(1) and any  Regulations  issued  thereunder  for
     taxable years beginning in such calendar year.

             SECTION 3 -- OPERATION OF FIXED INTEREST ACCOUNT (FIA)

3.1  Allocations  to  Participant   Accounts:  We  allocate  each  Participant's
     Contributions in the FIA based on the information you provide.

3.2  Provision of Guaranteed Rates for Interest  Pockets:  All  Contributions or
     transfers  hereunder  which  are  allocated  to the FIA  during a  Contract
     Quarter  will  earn  interest  at the  declared  Guaranteed  Rate  for that
     quarterly Interest Pocket until that pocket matures on the second January 1
     following  the  quarter  in  which  that  pocket  was  established.   Funds
     associated  with that maturing pocket will earn interest for a full year at
     the Guaranteed Rate for that pocket, which will be declared by January 1 of
     each year.

3.3  Minimum  Rate  Guarantee:  No  Guaranteed  Rate may be less  than an annual
     effective interest rate of 3.00%.

3.4  Allocation of  Withdrawals:  Withdrawals or transfers from the FIA are on a
     first-in/first-out basis.

                  SECTION 4 - VALUATION OF INVESTMENT ACCOUNTS

4.1  Operation of Investment Accounts: All income, gains, or losses, realized or
     unrealized,  from assets held in any Investment  Account are credited to or
     charged  against the applicable  Investment  Account  without regard to our
     other  income,  gains,  or  losses.   Investment  Account  assets  are  not
     chargeable  with  liabilities  arising  out of any  other  business  we may
     conduct.

4.2  Valuation  of Mutual  Funds:  The current  prospectus  for each Mutual Fund
     describes how that Mutual Fund's assets are valued.

4.3  Accumulation Units: We credit amounts allocated to an Investment Account in
     Accumulation  Units.  The  Accumulation  Unit value used is the one for the
     Valuation Period when we allocate the amount to the Investment Account.

4.4  Value of Accumulation  Units: We generally  establish the Accumulation Unit
     value for a new  Investment  Account at $1.00 on the date the first deposit
     is made to the Investment  Account.  The value of an Accumulation  Unit for
     any later Valuation Period equals the value of an Accumulation Unit for the
     immediately  preceding Valuation Period times the Net Investment Factor for
     the current  Valuation  Period.  We determine the  Accumulation  Unit value
     before giving  effect to any  additions,  withdrawals,  or transfers in the
     current Valuation Period.

4.5  Determining  the Net  Investment  Factor:  We determine the Net  Investment
     Factor  for  each  Investment  Account  by  dividing  (a) by (b),  and then
     subtracting (c), where:

     (a)  is:

          (1)  the net asset  value of a Mutual Fund or  Portfolio  share at the
               end of the current Valuation Period, plus

          (2)  any  dividend or other  distribution  paid on each Mutual Fund or
               Portfolio share during such Valuation Period, plus or minus

          (3)  any credit or charge for taxes paid or  reserved by us during the
               Valuation  Period  that  we  determine  are  attributable  to the
               Investment Account;

     (b)  is the net asset value of each Mutual Fund or Portfolio  share held in
          the Investment Account at the end of the prior Valuation Period; and

     (c)  is a daily charge factor we determine, as described in Section 8.1.

4.6  Valuing  Participant  Accounts:  We  determine  the  Account  Value  in  an
     Investment   Account  by  multiplying  the   Accumulation   Units  in  each
     Participant  Account by the Accumulation  Unit value. The Accumulation Unit
     value of an Investment Account changes only on a Business Day.

                          SECTION 5 - BENEFIT PAYMENTS

5.1  General Withdrawal Provisions:  Subject to the following provisions of this
     Section,  the Participant may direct us to withdraw all or a portion of his
     Account Value pursuant to Sections 5.2 and 5.3 to provide a cash payment to
     him.

     (a)  Amounts  attributable  to amounts  held as of December  31, 1988 under
          another  Code  Section  403(b)  annuity  contract  may be withdrawn to
          provide such benefits.

     (b)  Amounts  attributable to  Contributions  made other than pursuant to a
          salary  reduction  agreement  (within  the  meaning  of  Code  Section
          402(g)(3)(C)) may be withdrawn to provide such benefits.

     (c)  Amounts  attributable  to  Contributions  made  pursuant  to a  salary
          reduction agreement (within the meaning of Code Section  402(g)(3)(C))
          may  be  withdrawn  to  provide  such  benefits,   provided  that  any
          distribution  of such amount shall not occur until the Participant has
          either  attained age 59 1/2,  separated  from  service,  died,  become
          totally  disabled (as defined by the IRS),  or  experienced a hardship
          (as  defined  by  the  IRS).  However,  in  the  case  of  a  hardship
          withdrawal,  any  gain  credited  to  such  Contributions  may  not be
          withdrawn.

     (d)  Withdrawal  of any  amount  from this  contract  which is  transferred
          directly  by us pursuant to a  Participant's  instructions  to another
          tax-deferred  annuity funding  vehicle under  applicable IRS rules and
          regulations  is not the provision of a benefit for purposes of Section
          5.2. Any such  withdrawal is subject to  application of the Withdrawal
          Charge pursuant to Sectoion 5.3.

     (e)  If,  as  provided  in  Internal   Revenue  Code   Regulation   Section
          1.403(b)-2T   Q&A-2,   the   distributee  of  any  eligible   rollover
          distribution  elects  to have the  distribution  paid  directly  to an
          eligible  retirement  plan (as defined in Q&A-1 of that  Section)  and
          specifies the eligible retirement plan to which the distribution is to
          be  paid,  then  the  distribution  shall  be paid  to  that  eligible
          retirement plan in a direct rollover.

     (f)  We are not responsible for determining a Participant's compliance with
          the  requirements  above.  Any  withdrawal  request  submitted  by the
          Participant  must  include  certification  as to  the  purpose  of the
          withdrawal.   The   Participant   assumes  full   responsibility   for
          determining  whether any withdrawal is permitted under applicable law.
          We may rely solely  upon his  representations  made in the  withdrawal
          request.

     (g)  Withdrawals  from a  Participant  Account's  share  of any  Investment
          Option may not be made in an amount  less than the  smaller of $500 or
          the Participant  Account's entire share of the Investment Option. If a
          withdrawal  reduces the  Participant  Account's share of an Investment
          Option  to  less  than  $500,  such  remaining  share  shall  also  be
          withdrawn.

     (h)  A withdrawal request is effective, and the Account Value to be applied
          pursuant to Sections  5.2 and 5.3 is  determined,  on the Business Day
          that we receive a proper withdrawal request (or due proof of death, if
          received later).

     (i)  We will pay any cash  lump-sum to the  Participant  within 7 days from
          the  appropriate  Business Day as determined in Subsection  (h) above,
          except  as we may be  permitted  to  defer  such  payment  of  amounts
          withdrawn from the Variable Account in accordance with

P-K-TDAMFVA-GMDB(BR).9
<PAGE>

          appropriate  provisions of the federal securities laws. We reserve the
          right to defer the  payment  of amounts  withdrawn  from the FIA for a
          period of up to 6 months after we receive the withdrawal request.

     (j)  Withdrawals from a Participant Account's share of the FIA will be made
          on a first-in/first- out basis under Section 3.4.

     (k)  Where a  Participant  has  outstanding  loans under this  contract,  a
          partial  withdrawal by a Participant from the FIA is permitted only to
          the extent  that the  Participant's  remaining  FIA  Withdrawal  Value
          equals twice the total of his outstanding loans under this contract.

5.2  Benefit Payments:

     (a)  Subject to the  limitations  provided in Section 5.1, the  Participant
          may  direct us to  withdraw  all or a  portion  of his  Account  Value
          (subject to Section 8.4, and minus the Participant's  outstanding loan
          balance under this contract and any unpaid expense charges due on such
          loans)  to  provide  a  cash  payment  to  him  to  pay  benefits  for
          retirement,   disability,  termination  of  employment,  hardship,  or
          required  minimum  distribution  benefits  pursuant  to  Code  Section
          401(a)(9).  Such a withdrawal  is not subject to a Withdrawal  Charge.
          Other benefits, and direct transfers under Section 5.1(d), are subject
          to a Withdrawal Charge and are paid under Section 5.3.

     (b)  Subject to the  limitations  provided in Section 5.1,  upon receipt of
          instructions  and  of  due  proof  of  the   Participant's   (and,  if
          applicable, the beneficiary's) death prior to the date the Participant
          Account is closed, we will apply the Account Value (subject to Section
          8.4, and minus the  Participant's  outstanding loan balance under this
          contract  and any unpaid  expense  charges  due on such  loans) of the
          Participant Account for the purpose of providing a Death Benefit. Such
          a withdrawal is not subject to a Withdrawal  Charge. The Death Benefit
          will be paid to the Participant's  beneficiary according to the method
          of payment elected by the  beneficiary  (unless such method of payment
          was  previously   elected  by  the  Participant).   The  Participant's
          beneficiary may also designate a beneficiary.  This Death Benefit will
          be payable:

          (1)  in a single  sum or  other  method  not  provided  in (2)  below;
               provided,  however,  that the entire  Account  Value  (subject to
               Section 8.4, and minus the Participant's outstanding loan balance
               under this  contract and any unpaid  expense  charges due on such
               loans) must be paid to the  beneficiary on or before  December 31
               of the calendar year which contains the fifth  anniversary of the
               Participant's death, or

          (2)  as an annuity in  accordance  with the Annuity  Options  shown in
               Section  7.2  over a  period  not to  exceed  the  life  or  life
               expectancy  of the  beneficiary.  If the  beneficiary  is not the
               Participant's  surviving  spouse,  the  annuity  must begin on or
               before December 31 of the calendar year immediately following the
               calendar year in which the  Participant  died. If the beneficiary
               is the Participant's surviving spouse, the annuity need not begin
               before  December 31 of the calendar year in which the Participant
               would have attained age 70 1/2.


P-K-TDAMFVA-GMDB(BR).10

<PAGE>

          If a Participant dies on or after his Annuity  Commencement  Date, any
          interest  remaining  under the Annuity Option selected will be paid at
          least as rapidly as prior to the Participant's death.

          Any withdrawal  request under this Section must certify the purpose of
          the request.

5.3  Other Cash Benefits:  Subject to the  limitations  provided in Section 5.1,
     the  Participant  may direct us to make a cash payment from his Participant
     Account for the purpose of providing benefits not specifically described in
     Section 5.2.

     If the  entire  Account  Value is  withdrawn,  the amount  paid  equals the
     Withdrawal Value,  subject to any charges described in Section 8, and minus
     the  Participant's  outstanding  loan balance  under this  contract and any
     unpaid  expense  charges due on such  loans.  In all other  instances,  the
     Account  Value is  reduced  by an  amount  sufficient  to make the  payment
     requested and to cover the Withdrawal  Charge and any charges  described in
     Section 8.

                         SECTION 6 - TRANSFERS AND LOANS

6.1  Transfers  between  Investment  Options:  The  Participant may direct us to
     transfer amounts between Investment Options. Transfers are effective on the
     Business Day we receive the transfer  direction.  Transfer directions for a
     Participant Account may be made daily on any Business Day. We will make the
     transfer as  requested  within 7 days from the date we receive the request,
     except as we may be permitted  to defer the  transfer of amounts  withdrawn
     from the Variable Account in accordance with appropriate  provisions of the
     federal  securities  laws.  We  reserve  the right to defer a  transfer  of
     amounts  from the FIA for a period of up to 6 months  after we receive  the
     transfer request.

     Where a Participant has outstanding  loans under this contract,  a transfer
     from  the  FIA is  permitted  only to the  extent  that  the  Participant's
     remaining FIA  Withdrawal  Value equals twice the total of his  outstanding
     loans under this contract.

6.2  Minimum  Amounts:  The minimum  amount a  Participant  may transfer from an
     Investment Option is $500 or, if less, the Participant's  entire balance in
     that Investment Option. If a transfer reduces the Participant balance in an
     Investment Option to less than $500, the entire balance is transferred.

6.3  Maximum Amounts:  No more than 20% of a Participant's  FIA Account Value on
     the later of the  Contract  Date or the  Contract  Anniversary  immediately
     preceding the request for transfer may be  transferred  from the FIA during
     any Contract Year.  However, if the Participant's FIA Account Value is less
     than $2,500 on the later of the Contract  Date or the Contract  Anniversary
     immediately  preceding the request for transfer,  the amount  transferrable
     from the FIA for that  Participant  for that  Contract  Year is the minimum
     amount specified in Section 6.2.

6.4  Loans from the FIA:

     (a)  A  Participant  who has a FIA Account  Value may borrow money from us,
          using that FIA Account  Value as the only  security  for the loan,  by
          submitting a proper  written  request to us. The minimum amount of any
          single loan is $2,000.  The maximum amount that may be borrowed at any
          time is an amount  which,  when combined with the largest loan balance
          during the prior 12  months,  does not exceed the lesser of (l) 50% of
          the  Participant's   FIA  Withdrawal   Value,  or  (2)  $50,000.   The
          Participant's FIA Withdrawal  Value,  which must be at least twice the
          amount of the  outstanding  loan  balance,  serves as security for the
          loan, and continues to earn  interest.  Our payment of the loan amount
          may be delayed for up to 6 months.

     (b)  Interest  will be charged  for the loan,  and will  accrue on the loan
          balance from the loan  effective  date.  We declare the loan  interest
          rate at the  beginning of each  calendar  quarter.  The interest  rate
          charged is equal to the Moody's Corporate Bond Yield Average - Monthly
          Average Corporates as of the date of the loan, as published by Moody's
          Investors Service.  However,  no change from a previously  established
          rate  may be  made  in an  amount  less  than  .50%  in  any  periodic
          adjustment.  The loan balance is also subject to a loan expense charge
          equal to 2% of each loan repayment.

     (c)  Loans to  Participants  must be repaid to us within a term of 5 years,
          unless the Participant  certifies to us that the loan is to be used to
          acquire a principal  residence for the Participant,  in which case the
          term may be longer.  Loan repayments must be made at least  quarterly.
          Upon receipt of a repayment,  we deduct the 2% expense charge from the
          repayment, and

P-K-TDAMFVA-GMDB(BR).12
<PAGE>
          apply the balance of the repayment  first to any accrued  interest and
          then to the outstanding loan principal.

     (d)  If a loan either  remains unpaid at the end of its term, or if, at any
          time, l02% of the total of all the Participant's  loan balances equals
          the  Participant's FIA Withdrawal Value, then we deduct these balances
          plus an expense  charge equal to 2% of the  outstanding  loan balances
          from  the  Participant's  share  of  the  FIA.  If a  Participant  has
          outstanding  loans,  then  withdrawals  or  transfers  to the Variable
          Account  are  permitted  only to the  extent  that  the  Participant's
          remaining  FIA  Withdrawal   Value  equals  twice  the  total  of  any
          outstanding  loans of the  Participant  under the  contract.  All loan
          balances plus the 2% expense  charge must be paid or satisfied in full
          before any amount from the Participant's share of the FIA is paid as a
          full withdrawal, as a Death Benefit, upon annuitization, or as another
          permitted distribution.

     (e)  We may modify the loan  restrictions  or  limitations  stated above in
          this Section,  or may add new  restrictions  and  limitations,  to the
          extent necessary to comply with Code Section 72(p) or other applicable
          law, as determined solely by us.

<PAGE>
                              SECTION 7 - ANNUITIES

7.1  Annuity  Purchases:  The  Participant  may withdraw all or a portion of his
     Account  Value  (subject to Section  8.4,  and minus his  outstanding  loan
     balance  under this  contract  and any unpaid  expense  charges due on such
     loans) to provide an annuity, reflecting benefits. Such a withdrawal is not
     subject to a Withdrawal  Charge. On receipt of an annuity purchase request,
     we transfer the entire Participant  Account to the FIA. Such amounts remain
     in the FIA until  the  Annuity  Commencement  Date,  when the full  balance
     (including interest) is applied to purchase the annuity.

     The Participant's annuity purchase request must specify the purpose for the
     annuity, the election of an annuity option,  Annuity Commencement Date, any
     contingent  annuitant or  beneficiary,  and any  additional  information we
     require.  If the  Participant or any  contingent  annuitant dies before the
     Annuity Commencement Date, the annuity election is cancelled.

     The minimum amount which the  Participant  may apply to purchase an annuity
     is $10,000.

7.2  Annuity Options:  The Participant may elect any optional form of annuity we
     offer at the time of purchase. Available annuity options always include:

     (a)  Life  Annuity.  A monthly  annuity is payable as long as the annuitant
          lives, and ends with the last payment before the annuitant's death.

     (b)  Survivorship  Annuity.  A monthly  annuity  is  payable as long as the
          annuitant lives.  After the annuitant's death, all or a portion of the
          monthly  annuity is paid to the  contingent  annuitant  as long as the
          contingent annuitant lives.

     No annuity may have a certain period  extending  beyond the life expectancy
     of a Participant  or the joint life  expectancy  of a  Participant  and any
     contingent annuitant, as determined on the Annuity Commencement Date.

7.3  Determining Annuity Amount: We compute the annuity amount using the factors
     reflected in the Table of Guaranteed  Immediate  Annuities attached to this
     contract.  However,  if  our  current  single  premium,   nonparticipating,
     immediate annuity rates for this class of group annuity contracts  produces
     a higher monthly annuity than the Table of Guaranteed  Immediate Annuities,
     then that more favorable annuity rate is applied.

7.4  Proof of Age and Survival;  Minimum  Payments:  We may require proof of any
     annuitant's  or  contingent  annuitant's  date of birth  before  commencing
     payments under any annuity.  We may also require proof that an annuitant or
     contingent  annuitant is living  before  making any annuity  payment.  If a
     monthly annuity is less than our current  established  minimum payment,  we
     may make payments on a less-frequent basis or in a single sum.

7.5  Annuity  Certificates:  We issue to each  person  for  whom an  annuity  is
     purchased a certificate setting forth the annuity's amount and terms.

                 SECTION 8 - MORTALITY AND EXPENSE RISK CHARGES
                           AND ADMINISTRATIVE CHARGES


8.1  Investment  Account Mortality and Expense Risk Charges:  We deduct from the
     average daily net assets of each Investment Account the daily equivalent of
     an annual combined  mortality risk charge and expense risk charge of 1.25%.
     This charge is part of the Net Investment Factor, described in Section 4.5.

8.2  Administrative  Charge:  We deduct an  administrative  charge per  Contract
     Quarter  equal to the lesser of $7.50 or 0.5% of the  Account  Value on the
     last  day of  each  Contract  Quarter  from  each  Participant  Account  in
     existence on that day for as long as the Participant  Account is in effect.
     This  charge is to be prorated  among each  subaccount  of the  Participant
     Account which  corresponds to each  Investment  Option  utilized under this
     contract  by  that  Participant   Account.  If  the  entire  balance  of  a
     Participant   Account  is  withdrawn   pursuant  to  this   contract,   the
     administrative  charge attributable to the period of time which has elapsed
     since the first day of the  Contract  Quarter  in which the  withdrawal  of
     funds is made is not deducted from the amount withdrawn.

     There is no charge for a Participant for any Contract  Quarter in which the
     Participant's Account Value on the last day of that quarter is greater than
     $25,000.

8.3  Mutual Fund or Portfolio  Expense:  A Mutual Fund or  Portfolio  deducts an
     investment  advisory fee and other  expenses  from its net asset value,  as
     described  in  its  current   prospectus.   Amounts  deducted  may  include
     operational, organizational, and extraordinary expenses. Expenses vary from
     year-to-year.

8.4  Taxes:  We may deduct  charges  equal to any  premium tax we incur from the
     balance  applied  to  purchase  an annuity or at such other time as premium

9.1  Mutual  Amendment:  You and we may agree to any change or amendment to this
     Contract  without the consent of any other person or entity.  This contract

     Such authority may be delegated only by a written  agreement  signed by our
     corporate officer.

9.2  Rates and Section 8 Charges:  We may  announce  new  Guaranteed  Rates,  as

     declared  Guaranteed  Rate  applicable to an  established  Interest  Pocket

     Section 8, using the procedures of Section 9.4.

9.3  Conformance with Law: We may amend this contract at any time,  without your
     consent,  or that of any  other  person  or  entity,  if the  amendment  is

     of, any  provisions of federal or state laws.  Any such  amendment  will be
     delivered to you prior to its effective date.

9.4  Our Right to Initiate Changes: In addition to those amendments permitted by
     Sections  9.2  and  9.3,  we  may  initiate  an  additional   provision  or
     modification  of any  other  provision  of  this  contract  (including  the
     addition of a charge for transfers  between  Investment  Options) by giving
     you 60 days notice of such modification. Any such modification is effective
     without your affirmative assent.

9.5  Prohibited Amendments:

     (a)  Despite our right to initiate  changes  under  Section 9.4, we may not
          initiate  changes to the minimum  Guaranteed Rate specified in Section
          3.4 or change our obligation to set Guaranteed Rates for the period of
          time specified in Section 3.2.

     (b)  No  modification to this contract may change the terms of a previously
          purchased  annuity  or reduce any  interest  guarantee  applicable  to
          Participant Account FIA balances on the modification's effective date.

10.1 Ownership:  You own this contract. No other person or entity has any right,
     title,  or  interest in this  contract  or to amounts  received or credited
     under it until such amounts are made  available to them by you. All amounts

     obligated  to make only the  payments or  distributions  specified  in this
     contract.

10.2 Entire Contract: This contract and your application is the entire agreement
     between  you and us.  We are not a party to,  nor bound by, a plan,  trust,
     custodial agreement,  or other agreement,  or any amendment or modification
     to any of the same. We are not a fiduciary under this contract or under any
     such plan, trust, custodial agreement, or other agreement.

10.3 Benefit   Determinations:   The   Participant   will  furnish  us  whatever
     information  is necessary to establish  the  eligibility  for and amount of
     annuity or other  benefit due. We may rely solely on his  instructions  and
     certifications with respect to his benefits.

10.4 Termination  of Contract:  This  contract  terminates  automatically  if no
     amounts remain in either the FIA or any Investment Account.  However,  upon
     written  notice to us, you may stop making  Contributions  at any time.  We
     have the right to  refuse  Contributions  as of the last day of the  second
     month  following  the date that you are  notified  by us in writing of this
     fact.

10.5 Representations and Warranties:  You and we mutually represent and warrant,
     each to the  other,  that  each is  fully  authorized  to enter  into  this
     contract and that this contract is a valid and binding  obligation and that
     the  execution  of this  contract  does not  violate  any law,  regulation,
     judgment, or order by which the representing party is bound.

     We do not make any representation or warranty regarding the federal, state,
     or local tax  status of this  contract,  any  Participant  Account,  or any
     transaction involving this contract.

10.6 Contractholder  Representative;  Misstatement  of Data: You may designate a
     representative  to act on your behalf  under  Sections 2 or 3 or to receive
     any  payment  under  Section 5. We may rely on any  information  you,  your
     designee,  or a Participant furnish. We need not inquire as to the accuracy
     or  completeness of such  information.  If any essential data pertaining to
     any person has been omitted or misstated,  including, but not limited to, a
     misstatement of an annuitant's or contingent  annuitant's age, we will make
     an equitable  adjustment to provide the annuity or other benefit determined
     using correct data.

10.7 Requirement for Writing: When reference is made to you, your designee, or a
     Participant making a request or giving notice,  instruction,  or direction,
     such request, notice, instruction, or direction must be in writing, or in a
     form otherwise acceptable to us, and is effective when we receive it.

10.8 Quarterly Statement of Account Value:  Reasonably promptly after the end of
     each Contract Quarter, we will prepare a statement of the Account Value for
     each Participant Account.

10.9 Conformity  with Law: Any benefit  payable under this contract shall not be
     less than the minimum  benefit  required by the insurance laws of the state
     in which the contract is delivered.  Language in this contract referring to
     state  or  federal  tax,  securities,  or  other  statutes  or rules do not
     incorporate within this contract any such statutes or rules.

10.10 Sex and Number: Whenever the context so requires,  the plural includes the
     singular, the singular the plural, and the masculine the feminine.

10.11 Facility of  Payment:  If  any  Participant,   contingent  annuitant,   or
     beneficiary is legally incapable of giving a valid receipt for any payment,
     and no guardian has been appointed, we may pay the

P-K-TDAMFVA-GMDB(BR).17
<PAGE>
     person or persons who have assumed the care and  principal  support of such
     Participant,  contingent  annuitant,  or  beneficiary.  We may also pay you
     directly or as you otherwise instruct. Any such payment fully discharges us
     to the extent of such payment.

10.12 Voting: We own all Mutual Fund or Portfolio  shares held in an  Investment
     Account.  We exercise the voting  rights of such shares at all  shareholder
     meetings on all matters requiring  shareholder  voting under the Investment
     Company  Act  of  1940  or  other   applicable   laws.  Our  vote  reflects
     instructions  received  from  persons  having  the voting  interest  in the
     shares, as follows:

     (a)  The Participants have the voting interest under this contract.  Unless
          otherwise  required by  applicable  law,  the number of Mutual Fund or
          Portfolio  shares  for which we may  receive  voting  instructions  is
          determined  by dividing the aggregate  Account  Values in the affected
          Investment  Account  by the net  asset  value  of the  Mutual  Fund or
          Portfolio shares.  Fractional votes are counted.  Our determination is
          made as of the date used by the Mutual Fund or  Portfolio to determine
          shareholders eligible to vote.

     (b)  We vote shares  proportionally,  to reflect the voting instructions we
          receive  in  a  timely   manner   from   Participants   and  from  all
          contractholders.  If no timely voting  instructions  are received,  we
          vote  shares  proportionally,  to reflect the voting  instructions  we
          received in a timely manner for all other contracts.

     To the extent  permitted by  applicable  law, we may vote shares in our own
     right or may modify the above  procedures to reflect  changes in the law or
     its interpretation.

     We will provide  prospectuses  and other  reports as required by applicable
     federal law.

10.13 Acceptance of New Participants or  Contributions:  We may refuse to accept
     new Participants or new Contributions at any time.

10.14 AUL's Annual   Statement:   No  provision  of  this   contract   controls,
     determines,  or modifies  any AUL annual  statement  made to any  insurance
     department,  contractholder,  regulatory  body, or other  person.  Nor does
     anything  in such  annual  statement  control,  determine,  or  modify  the
     provisions of this contract.

10.15 AUL's Annual  Meeting:  Unless  otherwise  notified,  our  regular  annual
     meeting is held at our Home Office on the third  Thursday in February at 10
     a.m. Elections for directors are held at such annual meeting.

10.16 Nonforfeitability and Nontransferability: The entire Withdrawal Value of a
     Participant  Account under this contract is nonforfeitable at all times. No
     sum payable under this contract with respect to a Participant  may be sold,
     assigned,  discounted,  or pledged as collateral  for a loan or as security
     for the performance of an obligation or for any other purpose to any person
     or entity  other than us. In addition,  to the extent  permitted by law, no
     such sum shall in any way be subject to legal process requiring the payment
     of any claim against the payee.

                            SECTION 1 - DEFINITIONS

1.1  "Account Value" for your Participant Account as of a date is:

     (a)  your account's Fixed Interest Account (FIA) balance on that date; plus

     (b)  the  value of your  account's  Accumulation  Units in each  Investment
          Account on that date.

1.2  "Accumulation  Unit" is a valuation device used to measure increases in and
     decreases to the value of any Investment Account.

1.3  "Annuity Commencement Date" is the first day of the month an annuity begins
     under this contract. This date may not be later than the date your periodic
     benefits are required to commence under the Code.

1.4  "Business  Day" is any day both the New York  Stock  Exchange  and our Home
     Office are open for the general conduct of business.

1.5  "Code"  means  the  Internal  Revenue  Code of 1986,  as  amended,  and any
     applicable regulations or rulings thereunder.

1.6  The  "First  Contract  Anniversary"  is listed on the  Contract  face page.
     Subsequent "Contract  Anniversaries" are on the same day of each subsequent
     year.

1.7  "Contract Quarter" is each of the four successive  three-month periods in a
     Contract Year.

1.8  The first  "Contract  Year" starts on the Contract Date and ends on the day
     before the First Contract Anniversary. Each subsequent Contract Year starts
     on a Contract  Anniversary  and ends on the day  before  the next  Contract
     Anniversary.

1.9  "Contributions"  are amounts paid to us,  which we credit to a  Participant
     Account.  Contributions  include amounts transferred from another AUL group
     annuity contract.  Contributions include "Elective Deferrals," which means,
     with  respect to any taxable  year,  any  Contribution  made under a salary
     reduction agreement. A Contribution made under a salary reduction agreement
     is not  treated as an  Elective  Deferral  if,  under the salary  reduction
     agreement,  the  Contribution  is made  pursuant to a one-time  irrevocable
     election made by you at the time of initial  eligibility  to participate in
     the  agreement,  or is made pursuant to a similar  arrangement  involving a
     one-time  irrevocable  election  specified in Regulations  issued under the
     Code.

1.10 "Death Benefit" is the greater of:

     (a)  your Account Value as of the date the Death Benefit is calculated, or

     (b)  (1) the  Guaranteed  Minimum  Death  Benefit  (GMDB)  on the  Contract
          Anniversary immediately preceding the date of your death; increased by

          (2)  any   Contributions   made  for  you  since  the  last   Contract
               Anniversary; and reduced proportionately to reflect

          (3)  any  withdrawals  or  loans  for  you  since  the  last  Contract
               Anniversary.


P-C-TDAMFVA-GMDB(BR).3

<PAGE>

1.11 "Excess  Contributions"  are Contributions in excess of the applicable Code
     limits.

1.12 "Fixed  Interest  Account"  or "FIA" is the  portion of our  general  asset
     account as described in Section 3, to which  Contributions may be allocated
     for accumulation at the Guaranteed Rates.

1.13 The  "Guaranteed  Minimum  Death  Benefit"  or  "GMDB"  prior to the  first
     Contract  Anniversary is equal to the Contributions  made for you minus any
     of your  withdrawals or loans.  On each Contract  Anniversary  prior to, or
     concurrent with, your date of death,  the GMDB is reset,  based on your age
     on your last birthday, as follows:

     (a)  If you are less than 81 years of age, the GMDB is the greater of:

          (1)  your Account Value as of the current Contract Anniversary, or

          (2)  (i)  the   GMDB  as  of  the   immediately   preceding   Contract
               Anniversary; increased by

               (ii) any  Contributions   made  for  you  since  the  immediately
                    preceding Contract Anniversary;  and reduced proportionately
                    to reflect

               (iii)any  withdrawals  or loans  for you  since  the  immediately
                    preceding Contract Anniversary.

     (b)  If you are 81 years of age or older, the GMDB is equal to:

          (1)  the GMDB as of the immediately  preceding  Contract  Anniversary;
               increased by

          (2)  any  Contributions  made for you since the immediately  preceding
               Contract Anniversary; and reduced proportionately to reflect

          (3)  any withdrawals or loans for you since the immediately  preceding
               Contract Anniversary.

     As of your date of death, the GMDB ceases to increase or decrease in value.

1.14 "Guaranteed Rates" are the guaranteed annual effective rates of interest we
     credit to each Interest  Pocket.  A Guaranteed Rate may be modified only as
     described in Section 3.2.

1.15 "Home  Office"  is our  principal  office  in  Indianapolis,  Indiana.  For
     anything to be "received by AUL," it must be received at our Home Office.

1.16 "Interest  Pocket" means a tracking method which associates funds deposited
     into the FIA over a specific time period with a specific  Guaranteed  Rate,
     as described in Section 3. After the guaranteed  period provided in Section
     3.2 has  elapsed,  we may  consolidate  two or  more  Interest  Pockets  in
     conjunction with the announcement of new Guaranteed Rates.

1.17 "Investment  Account" means each distinct portfolio  established within our
     Variable Account and identified in the Table of Investment  Accounts in the
     Contract.  Amounts allocated to any Investment  Account are invested in the
     shares of the  corresponding  Mutual Fund or  Portfolio  identified  in the
     Table of Investment Accounts.  Our "Variable Account" is a separate account
     we maintain  under  Indiana law which is called the AUL American Unit Trust
     and which is registered under the Investment  Company Act of 1940 as a unit
     investment trust.


P-C-TDAMFVA-GMDB(BR).4
<PAGE>


1.18 "Investment  Option" is the FIA or any Investment  Account.  We reserve the
     right to provide other Investment Options under the Contract at any time.

1.19 "Mutual  Fund"  means  any  diversified,  open-end,  management  investment
     company  made  available  by us,  and  listed  in the  Table of  Investment
     Accounts in the Contract.

1.20 "Participant" is any person that has a Participant Account.

1.21 "Participant   Account"  is  an  account   under  the   Contract  for  each
     Participant.   We  credit   Contributions   to  Participant   Accounts  and
     Contribution-type subaccounts as the Contractholder directs.

1.22 "Portfolio" is a portfolio  established within a particular Mutual Fund, as
     described in the Mutual Fund's current prospectus.

1.23 "Valuation  Periods" start at the close of each Business Day and end at the
     close of the next Business Day.

1.24 The  "Withdrawal  Charge" is a percentage of your Account  Value  withdrawn
     under the Contract.  The Withdrawal Charge will not apply to Account Values
     withdrawn  to  provide a benefit  payment or an  annuity  as  described  in
     Sections  5.2  and  7.1,   respectively.   The  percentage  varies  by  the
     Participant  Account  Year in which  the  withdrawal  is made.  Your  first
     Participant Account Year begins on the date when we establish a Participant
     Account and credit the initial  Contribution  for you,  and ends on the day
     immediately  preceding the next  anniversary of such date. Each Participant
     Account Year thereafter  begins on such an anniversary date and ends on the
     day  immediately  preceding  the  next  succeeding  anniversary  date.  The
     Withdrawal Charge percentage is as follows:

                          During                              Withdrawal Charge
                 Participant Account Years                         Percentage
                 -------------------------                    -----------------
                           1                                           7%
                           2                                           6%
                           3                                           5%
                           4                                           4%
                           5                                           3%
                           6                                           2%
                           7                                           1%
                       Thereafter                                      0%

     In no event will the cumulative total of all Withdrawal Charges,  including
     those   previously   assessed   against  any  amount  withdrawn  from  your
     Participant Account, exceed 8.5% of total  Contributions  allocated to your
     Participant Account.

1.25 "Withdrawal  Value" is your Account  Value,  minus any  Withdrawal  Charge,
     outstanding loan balance, and expense charges due on such loans.

               SECTION 2 - ADMINISTRATION OF PARTICIPANT ACCOUNTS

2.1  How Contributions Are Handled: Contributions we receive are credited to the
     appropriate  Contribution-type  subaccounts of each Participant  Account as
     the  Contractholder  directs in its  allocation  instructions.  The initial
     Contribution for you is allocated to your Participant Account by the second
     Business  Day after we (1) receive the initial  Contribution  or, if later,
     (2) receive all data necessary to complete the allocation  (including  data
     required  to  establish  your  Participant   Account,  the  amount  of  the
     Contribution  for  you,  and  Investment  Option   elections.)   Subsequent
     Contributions are allocated to your Participant Account on the Business Day
     we (1)  receive  that  Contribution  or, if  later,  (2)  receive  all data
     necessary to complete the allocation.

     If we do not  receive  the data  required  to  establish  your  Participant
     Account  and the amount of a  Contribution  for you within 5 Business  Days
     after we first receive that Contribution,  we will return that Contribution
     to the Contractholder  unless the  Contractholder  consents to us retaining
     that  Contribution  until the earlier of (i) the date we receive  such data
     and amount and, therefore,  can properly allocate that Contribution to your
     Participant  Account  or  (ii) 25  days  from  the  date  we  receive  that
     Contribution.

     If we receive the data required to establish your  Participant  Account and
     the amount of a  Contribution  for you,  but we do not  receive  Investment
     Option elections for you, the Contribution is allocated to the AUL American
     Money Market Investment Account. When we receive all required data, amounts
     in the AUL American Money Market Investment  Account,  plus gains and minus
     losses,  are  transferred  to the  appropriate  Investment  Option for each
     designated Contribution-type.

     Participant  Accounts  may  be  allocated  to  Investment  Options  in  any
     increments  acceptable to us.  Investment Option elections remain in effect
     until  changed  by  the  Contractholder.  A  change  in  Investment  Option
     elections is made by giving us new Investment Option elections.

2.2  Transfers from Other Retirement Programs: We may accept amounts transferred
     from other Code Section 403(b) funding vehicles.  Such transferred amounts,
     as identified by the Contractholder, are credited to a rollover subaccount,
     under the appropriate Participant Account.

2.3  Excess   Contributions:   On  receipt  of  instructions  from  you  or  the
     Contractholder, we will withdraw Excess Contributions, plus gains and minus
     losses,  from your  Participant  Account  and return them to you, or as the
     Contractholder  directs.  Such  instructions  must  state the  amount to be
     returned and certify that such  Contributions are Excess  Contributions and
     that such return is permitted by the Code. A return of Excess Contributions
     is treated like a benefit payment under Section 5.2.

No   Participant is permitted to have Elective  Deferral  contributions  (within
     the meaning of Code Section  402(g)(3))  made during a calendar  year under
     the  Contract,  or  under  any  other  plans,  contracts,  or  arrangements
     maintained  by his employer,  in excess of the dollar  limitation in effect
     under Code Section  402(g)(1) and any  Regulations  issued  thereunder  for
     taxable years beginning in such calendar year.

2.4  Transfers from Other Contracts:  We may require amounts transferred to your
     Participant  Account from other AUL group annuity contracts to be deposited
     in the FIA. We will advise the  Contractholder  if this limitation  applies
     before accepting such a transfer.

             SECTION 3 -- OPERATION OF FIXED INTEREST ACCOUNT (FIA)

3.1  Allocations  to  Participant   Accounts:  We  allocate  each  Participant's
     Contributions  in the  FIA  based  on the  information  the  Contractholder
     provides.

3.2  Provision of Guaranteed Rates for Interest  Pockets:  All  Contributions or
     transfers  hereunder  which  are  allocated  to the FIA  during a  Contract
     Quarter  will  earn  interest  at the  declared  Guaranteed  Rate  for that
     quarterly Interest Pocket until that pocket matures on the second January 1
     following  the  quarter  in  which  that  pocket  was  established.   Funds
     associated  with that maturing pocket will earn interest for a full year at
     the Guaranteed Rate for that pocket, which will be declared by January 1 of
     each year.

3.3  Minimum  Rate  Guarantee:  No  Guaranteed  Rate may be less  than an annual
     effective interest rate of 3.00%.

3.4  Allocation of  Withdrawals:  Withdrawals or transfers from the FIA are on a
     first-in/first-out basis.

                  SECTION 4 - VALUATION OF INVESTMENT ACCOUNTS

4.1  Operation of Investment Accounts: All income, gains, or losses, realized or
     unrealized,  from assets held in any Investment  Account are credited to or
     charged  against the applicable  Investment  Account  without regard to our
     other  income,  gains,  or  losses.   Investment  Account  assets  are  not
     chargeable  with  liabilities  arising  out of any  other  business  we may
     conduct.

4.2  Valuation  of Mutual  Funds:  The current  prospectus  for each Mutual Fund
     describes how that Mutual Fund's assets are valued.

4.3  Accumulation Units: We credit amounts allocated to an Investment Account in
     Accumulation  Units.  The  Accumulation  Unit value used is the one for the
     Valuation Period when we allocate the amount to the Investment Account.

4.4  Value of Accumulation  Units: We generally  establish the Accumulation Unit
     value for a new  Investment  Account at $1.00 on the date the first deposit
     is made to the Investment  Account.  The value of an Accumulation  Unit for
     any later Valuation Period equals the value of an Accumulation Unit for the
     immediately  preceding Valuation Period times the Net Investment Factor for
     the current  Valuation  Period.  We determine the  Accumulation  Unit value
     before giving  effect to any  additions,  withdrawals,  or transfers in the
     current Valuation Period.

4.5  Determining  the Net  Investment  Factor:  We determine the Net  Investment
     Factor  for  each  Investment  Account  by  dividing  (a) by (b),  and then
     subtracting (c), where:

     (a)  is:

          (1)  the net asset  value of a Mutual Fund or  Portfolio  share at the
               end of the current Valuation Period, plus

          (2)  any  dividend or other  distribution  paid on each Mutual Fund or
               Portfolio share during such Valuation Period, plus or minus

          (3)  any credit or charge for taxes paid or  reserved by us during the
               Valuation  Period  that  we  determine  are  attributable  to the
               Investment Account;

     (b)  is the net asset value of each Mutual Fund or Portfolio  share held in
          the Investment Account at the end of the prior Valuation Period; and

     (c)  is a daily charge factor we determine, as described in Section 8.1.

4.6  Valuing Your  Participant  Account:  We determine  your Account Value in an
     Investment   Account  by  multiplying  the   Accumulation   Units  in  your
     Participant  Account by the Accumulation  Unit value. The Accumulation Unit
     value of an Investment Account changes only on a Business Day.

                          SECTION 5 - BENEFIT PAYMENTS

5.1  General Withdrawal Provisions:  Subject to the following provisions of this
     Section,  you may direct us to  withdraw  all or a portion of your  Account
     Value pursuant to Sections 5.2 and 5.3 to provide a cash payment to you.

     (a)  Amounts  attributable  to amounts  held as of December  31, 1988 under
          another  Code  Section  403(b)  annuity  contract  may be withdrawn to
          provide such benefits.

     (b)  Amounts  attributable to  Contributions  made other than pursuant to a
          salary  reduction  agreement  (within  the  meaning  of  Code  Section
          402(g)(3)(C)) may be withdrawn to provide such benefits.

     (c)  Amounts  attributable  to  Contributions  made  pursuant  to a  salary
          reduction agreement (within the meaning of Code Section  402(g)(3)(C))
          may  be  withdrawn  to  provide  such  benefits,   provided  that  any
          distribution  of such  amount  shall not occur  until you have  either
          attained age 59 1/2,  separated  from service,  died,  become  totally
          disabled  (as  defined by the IRS),  or  experienced  a  hardship  (as
          defined by the IRS).  However,  in the case of a hardship  withdrawal,
          any gain credited to such Contributions may not be withdrawn.

     (d)  Withdrawal  of any  amount  from the  Contract  which  is  transferred
          directly by us pursuant to your  instructions to another  tax-deferred
          annuity funding vehicle under  applicable IRS rules and regulations is
          not the  provision  of a benefit for purposes of Section 5.2. Any such
          withdrawal is subject to application of the Withdrawal Charge pursuant
          to Section 5.3.

     (e)  If,  as  provided  in  Internal   Revenue  Code   Regulation   Section
          1.403(b)-2T   Q&A-2,   the   distributee  of  any  eligible   rollover
          distribution  elects  to have the  distribution  paid  directly  to an
          eligible  retirement  plan (as defined in Q&A-1 of that  Section)  and
          specifies the eligible retirement plan to which the distribution is to
          be  paid,  then  the  distribution  shall  be paid  to  that  eligible
          retirement plan in a direct rollover.

     (f)  We are not  responsible  for  determining  your  compliance  with  the
          requirements  above.  Any  withdrawal  request you submit must include
          your  certification  as to the purpose of the  withdrawal.  You assume
          full   responsibility  for  determining   whether  any  withdrawal  is
          permitted  under   applicable  law.  We  may  rely  solely  upon  your
          representations made in the withdrawal request.

     (g)  Withdrawals  from your  Participant  Account's share of any Investment
          Option may not be made in an amount  less than the  smaller of $500 or
          your entire share of the Investment  Option.  If a withdrawal  reduces
          your share of an  Investment  Option to less than $500,  the remaining
          share will also be withdrawn.

     (h)  A withdrawal request is effective, and the Account Value to be applied
          pursuant to Sections  5.2 and 5.3 is  determined,  on the Business Day
          that we receive a proper withdrawal request (or due proof of death, if
          received later).

     (i)  We  will  pay  any  cash  lump-sum  to  you  within  7 days  from  the
          appropriate Business Day as determined in Subsection (h) above, except
          as we may be permitted to defer such payment of amounts withdrawn from
          the Variable Account in accordance with appropriate

P-C-TDAMFVA-GMDB(BR).9
<PAGE>



          provisions  of the federal  securities  laws.  We reserve the right to
          defer the payment of  provisions  of the federal  securities  laws. We
          reserve the right to defer the payment of amounts  withdrawn  from the
          FIA for a period of up to 6 months  after we  receive  the  withdrawal
          request.

     (j)  Withdrawals   from   your   share  of  the  FIA  will  be  made  on  a
          first-in/first-out basis under Section 3.4.

     (k)  Where  you have  outstanding  loans  under  the  Contract,  a  partial
          withdrawal  by you from the FIA is  permitted  only to the extent that
          your  remaining  FIA  Withdrawal  Value equals twice the total of your
          outstanding loans under the Contract.

5.2  Benefit Payments:

     (a)  Subject to the limitations  provided in Section 5.1, you may direct us
          to withdraw all or a portion of your Account Value (subject to Section
          8.4, and minus your  outstanding  loan balance  under the Contract and
          any  unpaid  expense  charges  due on such  loans)  to  provide a cash
          payment to you to pay benefits for retirement, disability, termination
          of employment,  hardship,  or required minimum  distribution  benefits
          pursuant to Code Section  401(a)(9).  Such a withdrawal is not subject
          to a Withdrawal Charge.

     (b)  Subject to the  limitations  provided in Section 5.1,  upon receipt of
          instructions  and of due  proof  of  your  (and,  if  applicable,  the
          beneficiary's)  death  prior to the date your  Participant  Account is
          closed,  we will apply the Account Value  (subject to Section 8.4, and
          minus your outstanding loan balance under this contract and any unpaid
          expense charges due on such loans) of your Participant Account for the
          purpose of providing a Death Benefit. Such a withdrawal is not subject
          to a  Withdrawal  Charge.  The  Death  Benefit  will  be  paid to your
          beneficiary  according  to the  method  of  payment  elected  by  your
          beneficiary  (unless such method of payment was previously  elected by
          you). Your  beneficiary  may also designate a beneficiary.  This Death
          Benefit will be payable:

          (1)  in a single  sum or  other  method  not  provided  in (2)  below;
               provided,  however,  that the entire  Account  Value  (subject to
               Section 8.4, and minus your  outstanding  loan balance  under the
               Contract and any unpaid  expense  charges due on such loans) must
               be paid to  your  beneficiary  on or  before  December  31 of the
               calendar year which contains the fifth anniversary of your death,
               or

          (2)  as an annuity in  accordance  with the Annuity  Options  shown in
               Section  7.2  over a  period  not to  exceed  the  life  or  life
               expectancy of your  beneficiary.  If your beneficiary is not your
               surviving spouse, the annuity must begin on or before December 31
               of the calendar year  immediately  following the calendar year in
               which you die. If the beneficiary is your surviving  spouse,  the
               annuity need not begin before December 31 of the calendar year in
               which you would have attained age 70 1/2.

          If you die on or after your Annuity  Commencement  Date,  any interest
          remaining  under the Annuity Option  selected will be paid at least as
          rapidly as prior to your death.

Any  withdrawal  request  under this  Section  must  certify  the purpose of the
request.

5.3  Other Cash Benefits:  Subject to the  limitations  provided in Section 5.1,
     you may direct us to make a cash payment from your Participant  Account for
     the purpose of  providing  benefits not  specifically  described in Section
     5.2.

     If the  entire  Account  Value is  withdrawn,  the amount  paid  equals the
     Withdrawal Value,  subject to any charges described in Section 8, and minus
     your  outstanding  loan balance  under the Contract and any unpaid  expense
     charges due on such loans.  In all other  instances,  the Account  Value is
     reduced by an amount  sufficient to make the payment requested and to cover
     the Withdrawal Charge and any charges described in Section 8.

                         SECTION 6 - TRANSFERS AND LOANS

6.1  Transfers between Investment Options: You may direct us to transfer amounts
     between Investment Options.  Transfers are effective on the Business Day we
     receive your transfer  direction.  Transfer  directions for you may be made
     daily on any Business Day. We will make the transfer as requested  within 7
     days from the date we receive the request, except as we may be permitted to
     defer the  transfer  of  amounts  withdrawn  from the  Variable  Account in
     accordance with appropriate  provisions of the federal  securities laws. We
     reserve the right to defer a transfer of amounts  from the FIA for a period
     of up to 6 months after we receive your transfer request.

     Where you have  outstanding  loans under the Contract,  a transfer from the
     FIA is  permitted  only to the extent that your  remaining  FIA  Withdrawal
     Value equals twice the total of your outstanding loans under the Contract.

6.2  Minimum  Amounts:  The minimum  amount you may transfer  from an Investment
     Option is $500 or, if less, your entire balance in that Investment  Option.
     If a transfer  reduces  your balance in an  Investment  Option to less than
     $500, the entire balance is transferred.

6.3  Maximum Amounts: No more than 20% of your FIA Account Value on the later of
     the Contract  Date or the Contract  Anniversary  immediately  preceding the
     request for  transfer may be  transferred  from the FIA during any Contract
     Year.  However,  if your FIA Account Value is less than $2,500 on the later
     of the Contract Date or the Contract Anniversary  immediately preceding the
     request for  transfer,  the amount  transferrable  from the FIA for you for
     that Contract Year is the minimum amount specified in Section 6.2.

6.4  Loans from the FIA:

     (a)  If you have a FIA Account  Value,  you may borrow money from us, using
          that  FIA  Account  Value  as the  only  security  for  the  loan,  by
          submitting a proper  written  request to us. The minimum amount of any
          single loan is $2,000.  The maximum amount that may be borrowed at any
          time is an amount  which,  when combined with the largest loan balance
          during the prior 12  months,  does not exceed the lesser of (l) 50% of
          your FIA Withdrawal Value, or (2) $50,000.  Your FIA Withdrawal Value,
          which  must be at least  twice  the  amount  of the  outstanding  loan
          balance,  serves as  security  for the  loan,  and  continues  to earn
          interest.  Our  payment of the loan  amount may be delayed for up to 6
          months.

     (b)  Interest  will be charged  for the loan,  and will  accrue on the loan
          balance from the loan  effective  date.  We declare the loan  interest
          rate at the  beginning of each  calendar  quarter.  The interest  rate
          charged is equal to the Moody's Corporate Bond Yield Average - Monthly
          Average Corporates as of the date of the loan, as published by Moody's
          Investors Service.  However,  no change from a previously  established
          rate  may be  made  in an  amount  less  than  .50%  in  any  periodic
          adjustment.  The loan balance is also subject to a loan expense charge
          equal to 2% of each loan repayment.

     (c)  Loans  must be  repaid  to us  within  a term of 5 years,  unless  you
          certify  to us that the loan is to be used to acquire  your  principal
          residence,  in which case the term may be longer. Loan repayments must
          be made at least quarterly. Upon receipt of a repayment, we deduct the
          2% expense  charge  from the  repayment,  and apply the balance of the
          repayment  first to any accrued  interest and then to the  outstanding
          loan principal.

P-C-TDAMFVA-GMDB(BR).12
<PAGE>

     (d)  If a loan either  remains unpaid at the end of its term, or if, at any
          time,  l02% of the total of all your  loan  balances  equals  your FIA
          Withdrawal Value, then we deduct these balances plus an expense charge
          equal to 2% of the  outstanding  loan  balances from your share of the
          FIA. If you have outstanding  loans,  then withdrawals or transfers to
          the  Variable  Account  are  permitted  only to the  extent  that your
          remaining  FIA  Withdrawal  Value  equals  twice  the  total  of  your
          outstanding  loans under the  contract.  All loan balances plus the 2%
          expense  charge  must be paid or  satisfied  in full before any amount
          from your  share of the FIA is paid as a full  withdrawal,  as a Death
          Benefit, upon annuitization, or as another permitted distribution.

     (e)  We may modify the loan  restrictions  or  limitations  stated above in
          this Section,  or may add new  restrictions  and  limitations,  to the
          extent necessary to comply with Code Section 72(p) or other applicable
          law, as determined solely by us.

                              SECTION 7 - ANNUITIES

7.1  Annuity Purchases:  You may withdraw all or a portion of your Account Value
     (subject to Section 8.4, and minus your  outstanding loan balance under the
     Contract  and any unpaid  expense  charges due on such loans) to provide an
     annuity,  reflecting  benefits.  Such  a  withdrawal  is not  subject  to a
     Withdrawal  Charge. On receipt of an annuity purchase request,  we transfer
     your entire Participant  Account to the FIA. Such amounts remain in the FIA
     until the  Annuity  Commencement  Date,  when the full  balance  (including
     interest) is applied to purchase the annuity.

     Your annuity purchase request must specify the purpose for the annuity, the
     election of an annuity option,  Annuity  Commencement  Date, any contingent
     annuitant or beneficiary, and any additional information we require. If you
     or any contingent  annuitant dies before the Annuity Commencement Date, the
     annuity election is cancelled.

     The minimum amount which you may apply to purchase an annuity is $5,000.

7.2  Annuity Options: You may elect any optional form of annuity we offer at the
     time of purchase. Available annuity options always include:

     (a)  Life  Annuity.  A monthly  annuity is payable as long as the annuitant
          lives, and ends with the last payment before the annuitant's death.

     (b)  Survivorship  Annuity.  A monthly  annuity  is  payable as long as the
          annuitant lives.  After the annuitant's death, all or a portion of the
          monthly  annuity is paid to the  contingent  annuitant  as long as the
          contingent annuitant lives.

     No annuity may have a certain period  extending beyond your life expectancy
     or the  joint  life  expectancy  of you and any  contingent  annuitant,  as
     determined on the Annuity Commencement Date.

7.3  Determining Annuity Amount: We compute the annuity amount using the factors
     reflected in the Table of Guaranteed  Immediate  Annuities  attached to the
     Contract.  However,  if  our  current  single  premium,   nonparticipating,
     immediate annuity rates for this class of group annuity contracts  produces
     a higher monthly annuity than the Table of Guaranteed  Immediate Annuities,
     then that more favorable annuity rate is applied.

7.4  Proof of Age and Survival;  Minimum  Payments:  We may require proof of any
     annuitant's  or  contingent  annuitant's  date of birth  before  commencing
     payments under any annuity.  We may also require proof that an annuitant or
     contingent  annuitant is living  before  making any annuity  payment.  If a
     monthly annuity is less than our current  established  minimum payment,  we
     may make payments on a less-frequent basis or in a single sum.

7.5  Annuity  Certificates:  We issue to each  person  for  whom an  annuity  is
     purchased a certificate setting forth the annuity's amount and terms.

                 SECTION 8 - MORTALITY AND EXPENSE RISK CHARGES
                           AND ADMINISTRATIVE CHARGES


8.1  Investment  Account Mortality and Expense Risk Charges:  We deduct from the
     average daily net assets of each Investment Account the daily equivalent of
     an annual combined  mortality risk charge and expense risk charge of 1.25%.
     This charge is part of the Net Investment Factor, described in Section 4.5.

8.2  Administrative  Charge:  We deduct an  administrative  charge per  Contract
     Quarter  equal to the lesser of $7.50 or 0.5% of your Account  Value on the
     last day of each  Contract  Quarter  from your  Participant  Account  if it
     exists on that day, for as long as your  Participant  Account is in effect.
     This charge is to be prorated  among each  subaccount  of your  Participant
     Account which  corresponds  to each  Investment  Option  utilized under the
     Contract  by  your  Participant  Account.  If the  entire  balance  of your
     Participant   Account  is   withdrawn   pursuant  to  the   Contract,   the
     administrative  charge attributable to the period of time which has elapsed
     since the first day of the  Contract  Quarter  in which the  withdrawal  of
     funds is made is not deducted from the amount withdrawn.

     There is no charge for any Contract  Quarter in which your Account Value on
     the last day of that quarter is greater than $25,000.

8.3  Mutual Fund or Portfolio  Expense:  A Mutual Fund or  Portfolio  deducts an
     investment  advisory fee and other  expenses  from its net asset value,  as
     described  in  its  current   prospectus.   Amounts  deducted  may  include
     operational, organizational, and extraordinary expenses. Expenses vary from
     year-to-year.

8.4  Taxes:  We may deduct  charges  equal to any  premium tax we incur from the
     balance  applied  to  purchase  an annuity or at such other time as premium
     taxes are  incurred  by us. We may also  deduct  from  Investment  Accounts
     reasonable charges for federal, state, or local income taxes we incur, that
     are attributable to such Investment Accounts.

8.5  Reduction  or  Waiver of  Charges:  We may  reduce or waive the  Withdrawal
     Charge  or  the  charges  discussed  above,  if  the  appropriate  expenses
     associated with the sale or administration of any contract are reduced,  or
     if a contract is sold covering our employees or directors, those of the AUL
     American Series Fund, Inc., or to either's affiliates.

9.1  Mutual  Amendment:  The  Contractholder  and we may agree to any  change or
     amendment  to the  Contract  without  the  consent  of any other  person or
     entity.  The Contract cannot be modified or amended,  nor can any provision
     or  condition  be  waived,  except by our  written  agreement,  signed by a
     corporate  officer.  Such  authority  may be  delegated  only by a  written
     agreement signed by our corporate officer.

9.2  Rates and Section 8 Charges:  We may  announce  new  Guaranteed  Rates,  as
     described in Section 3.2 (including the  consolidation of existing Interest
     Pockets).  However,  as  provided  in  Section  3.2,  we may not change the
     declared  Guaranteed  Rate  applicable to an  established  Interest  Pocket
     during the  guaranteed  period.  We may also  modify  the charge  levels in
     Section 8, using the procedures of Section 9.4.

9.3  Conformance  with Law: We may amend the  Contract at any time,  without the
     Contractholder's  consent,  or that of any other  person or entity,  if the
     amendment  is  reasonably  needed  to  comply  with,  or  give  you  or the
     Contractholder the benefit of, any provisions of federal or state laws. Any
     such  amendment  will  be  delivered  to the  Contractholder  prior  to its
     effective date.

9.4  Our Right to Initiate Changes: In addition to those amendments permitted by
     Sections  9.2  and  9.3,  we  may  initiate  an  additional   provision  or
     modification of any other provision of the Contract (including the addition
     of a charge  for  transfers  between  Investment  Options)  by  giving  the
     Contractholder 60 days notice of such  modification.  Any such modification
     is effective without the Contractholder's affirmative assent.

9.5  Prohibited Amendments:

     (a)  Despite our right to initiate  changes  under  Section 9.4, we may not
          initiate  changes to the minimum  Guaranteed Rate specified in Section
          3.4 or change our obligation to set Guaranteed Rates for the period of
          time specified in Section 3.2.

     (b)  No  modification  to the Contract may change the terms of a previously
          purchased annuity or reduce any interest guarantee  applicable to your
          Participant Account FIA balance on the modification's effective date.

                         SECTION 10 - GENERAL PROVISIONS

10.1 Ownership:  The Contractholder owns the Contract. No other person or entity
     has any right, title, or interest in the Contract or to amounts received or
     credited  under it until such  amounts  are made  available  to them by the
     Contractholder.  All amounts received or credited under the Contract become
     our property.  We are obligated to make only the payments or  distributions
     specified in the Contract.

10.2 Entire Contract:  The Contract and the Contractholder's  application is the
     entire agreement between the  Contractholder and us. We are not a party to,
     nor bound by, a plan, trust,  custodial agreement,  or other agreement,  or
     any  amendment or  modification  to any of the same. We are not a fiduciary
     under the Contract or under any such plan, trust,  custodial agreement,  or
     other agreement.

10.3 Benefit  Determinations:  You  must  furnish  us  whatever  information  is
     necessary to establish the  eligibility  for and amount of annuity or other
     benefit  due. We may rely solely on your  instructions  and  certifications
     with respect to your benefits.

10.4 Termination  of  Contract:  The  Contract  terminates  automatically  if no
     amounts remain in either the FIA or any Investment Account.  However,  upon
     written notice to us, the Contractholder  may stop making  Contributions at
     any time. We have the right to refuse  Contributions  as of the last day of
     the second month following the date we notify the Contractholder in writing
     of this fact.

10.5 Representations   and  Warranties:   The  Contractholder  and  we  mutually
     represent and warrant,  each to the other, that each is fully authorized to
     enter  into the  Contract  and that the  Contract  is a valid  and  binding
     obligation and that the execution of the Contract does not violate any law,
     regulation, judgment, or order by which the representing party is bound.

     We do not make any representation or warranty regarding the federal, state,
     or local tax  status  of the  Contract,  any  Participant  Account,  or any
     transaction involving the Contract.

10.6 Contractholder Representative; Misstatement of Data: The Contractholder may
     designate a representative to act on its behalf under Sections 2 or 3 or to
     receive any payment  under  Section 5.  We may rely on any information  the
     Contractholder, its designee, or you furnish. We need not inquire as to the
     accuracy  or  completeness  of  such  information.  If any  essential  data
     pertaining to any person has been omitted or misstated,  including, but not
     limited to, a misstatement of an annuitant's or contingent annuitant's age,
     we will make an  equitable  adjustment  to  provide  the  annuity  or other
     benefit determined using correct data.

10.7 Requirement for Writing: When reference is made to the Contractholder,  its
     designee,  or you  making a  request  or  giving  notice,  instruction,  or
     direction,  such  request,  notice,  instruction,  or direction  must be in
     writing, or in a form otherwise  acceptable to us, and is effective when we
     receive it.

10.8 Quarterly Statement of Account Value:  Reasonably promptly after the end of
     each Contract Quarter, we will prepare a statement of the Account Value for
     your Participant Account.

10.9 Conformity  with Law: Any benefit  payable under the Contract  shall not be
     less than the minimum  benefit  required by the insurance laws of the state
     in which the Contract is delivered.  Language in the Contract  referring to
     state  or  federal  tax,  securities,  or  other  statutes  or rules do not
     incorporate within the Contract any such statutes or rules.

10.10 Sex and Number:
     Whenever the context so requires,  the plural  includes the  singular,  the
     singular the plural, and the masculine the feminine.

10.11 Facility of Payment:
     If you, your contingent annuitant, or your beneficiary is legally incapable
     of  giving  a valid  receipt  for any  payment,  and no  guardian  has been
     appointed,  we may pay the person or persons who have  assumed the care and
     principal support of you, your contingent  annuitant,  or your beneficiary.
     We may also pay the Contractholder  directly or as it otherwise  instructs.
     Any such payment fully discharges us to the extent of such payment.

10.12 Voting:
     We own all Mutual Fund or Portfolio  shares held in an Investment  Account.
     We exercise the voting rights of such shares at all shareholder meetings on
     all matters requiring  shareholder  voting under the Investment Company Act
     of 1940 or other applicable laws. Our vote reflects  instructions  received
     from persons having the voting interest in the shares, as follows:

     (a)  The Participants  have the voting interest under the Contract.  Unless
          otherwise  required by  applicable  law,  the number of Mutual Fund or
          Portfolio  shares  for which we may  receive  voting  instructions  is
          determined  by dividing the aggregate  Account  Values in the affected
          Investment  Account  by the net  asset  value  of the  Mutual  Fund or
          Portfolio shares.  Fractional votes are counted.  Our determination is
          made as of the date used by the Mutual Fund or  Portfolio to determine
          shareholders eligible to vote.

     (b)  We vote shares  proportionally,  to reflect the voting instructions we
          receive  in  a  timely   manner   from   Participants   and  from  all
          contractholders.  If no timely voting  instructions  are received,  we
          vote  shares  proportionally,  to reflect the voting  instructions  we
          received in a timely manner for all other contracts.

     To the extent  permitted by  applicable  law, we may vote shares in our own
     right or may modify the above  procedures to reflect  changes in the law or
     its interpretation.

     We will provide  prospectuses  and other  reports as required by applicable
     federal law.

10.13 Acceptance of New Contributions:
     We may refuse to accept new Contributions at any time.

10.14 AUL's Annual Statement:
     No  provision  of the Contract  controls,  determines,  or modifies any AUL
     annual  statement  made  to  any  insurance   department,   contractholder,
     regulatory  body,  or  other  person.  Nor  does  anything  in such  annual
     statement control, determine, or modify the provisions of the Contract.

10.15 AUL's Annual Meeting:
     Unless otherwise  notified,  our regular annual meeting is held at our Home
     Office on the third Thursday in February at 10 a.m. Elections for directors
     are held at such annual meeting.

10.16 Nonforfeitability and Nontransferability:
     The entire Withdrawal Value of your Participant  Account under the Contract
     is  nonforfeitable  at all times.  No sum payable  under the Contract  with
     respect to you may be sold, assigned,  discounted, or pledged as collateral
     for a loan or as security for the  performance  of an obligation or for any
     other  purpose to any person or entity other than us. In  addition,  to the
     extent  permitted  by law, no such sum shall in any way be subject to legal
     process requiring the payment of any claim against the payee.
