                       PLEASE READ THIS CONTRACT CAREFULLY


ANNUITY BENEFIT PAYMENTS AND OTHER VALUES PROVIDED BY THIS CONTRACT, WHEN BASED
ON THE INVESTMENT PERFORMANCE OF THE VARIABLE ACCOUNT, MAY INCREASE OR DECREASE
AND ARE NOT GUARANTEED AS TO FIXED DOLLAR AMOUNT. PLEASE REFER TO THE VALUE OF
THE VARIABLE ACCOUNT SECTION FOR ADDITIONAL INFORMATION.

Values removed from a Guarantee Period Account prior to the end of its Guarantee
Period may be subject to a Market Value Adjustment that may increase or decrease
the values. A negative Market Value Adjustment will never be applied to the
Death Benefit. A positive Market Value Adjustment, if applicable, will be added
to the Death Benefit when the benefit paid is the contract's Accumulated Value.
Please refer to the Market Value Adjustment section for additional information.

                            RIGHT TO EXAMINE CONTRACT

The Owner may cancel this contract by returning it to the Company or one of its
authorized representatives within ten days after receipt. If returned, the
Company will refund an amount equal to the Accumulated Value, after application
of any Market Value Adjustment, plus any fees or other charges imposed. If,
however, the contract is issued as an Individual Retirement Annuity (IRA), the
Company will refund the greater of the above or gross payments.

                               Benefit Percentage is 66 2/3%. This percentage is
                               only applicable after the death of the first

                                 OWNER, ANNUITANT AND BENEFICIARY


Owner                          When the contract is issued, the Owner will be as
                               shown on the Specifications page. The Owner may
                               be changed in accordance with the terms of this
                               contract. Upon the death of an Owner prior to the
                               Annuity Date, a Death Benefit is paid. The
                               Maximum Alternative Annuity Date is based upon
                               the age of the Owner.

                               The Owner may exercise all rights and options
                               granted in this contract or by the Company,
                               subject to the consent of any irrevocable
                               Beneficiary. Where there are joint Owners, the
                               consent of both is required in order to exercise
                               any ownership rights.

Assignment                     Prior to the Annuity Date and prior to the death
                               of an Owner, the Owner may be changed at any
                               time. Only the Owner may assign this contract. An
                               absolute assignment will transfer ownership to
                               the assignee. This contract may also be
                               collaterally assigned as security. The
                               limitations on ownership rights while the
                               collateral assignment is in effect are stated in
                               the assignment. Additional limitations may exist
                               for contracts issued under provisions of the
                               Internal Revenue Code.

                               An assignment will take place only when the
                               Company has actually received a Request in
                               writing and recorded the change at the Principal
                               Office. The Company will not be deemed to know of
                               the assignment until such time. When recorded,
                               the assignment will take effect as of the date it
                               was signed. The assignment will be subject to
                               payments made or actions taken by the Company
                               before the change was recorded.

                               The Company will not be responsible for the
                               validity of any assignment nor the extent of any
                               assignee's interest. The interests of the
                               Beneficiary will be subject to any assignment.

Annuitant                      When the contract is issued, the Annuitant will
                               be as shown on the Specifications page. The
                               Annuitant may be changed in accordance with the
                               terms of this contract. Prior to the Annuity
                               Date, an Annuitant may be replaced or added
                               unless the Owner is a non-natural person. At
                               all times there must be at least one Annuitant.
                               If the Annuitant dies and a replacement is not
                               named, the Owner will be considered to be the
                               new Annuitant. Upon the death of an Annuitant
                               prior to the Annuity Date, a Death Benefit is
                               not paid unless the Owner is a non-natural
                               person.

                               A change of Annuitant will take place only when
                               the Company has actually received a Request in
                               writing and recorded the change at the Principal
                               Office. The Company will not be deemed to
                               know of the change of Annuitant until such time.
                               When recorded, the change of Annuitant will
                               take effect as of the date it was signed. The
                               change of Annuitant will be subject to payments
                               made or actions taken by the Company before the
                               change was recorded.

Beneficiary                    The Beneficiary is as named on the Specifications
                               page unless subsequently changed. The Owner may
                               declare any Beneficiary to be revocable or
                               irrevocable. A revocable Beneficiary may be
                               changed at any time prior to the Annuity Date and
                               before the death of an Owner or after the Annuity
                               Date and before the death of the Annuitant.

Form A3036-01                         11                                 BACS11

<Page>
                               An irrevocable Beneficiary must consent in
                               writing to any change. Unless otherwise
                               indicated, the Beneficiary will be revocable.

                               A Beneficiary change must be made in writing in
                               a form acceptable to the Company and will be
                               subject to the rights of any assignee of record.
                               When the Company receives the form, the change
                               will take place as of the date it was signed,
                               even if an Owner or the Annuitant dies after the
                               form is signed but prior to the Company's receipt
                               of the form. Any rights created by the change
                               will be subject to payments made or actions taken
                               by the Company before the change was recorded.

                               All benefits payable to the Beneficiary under
                               this contract will be divided equally among the
                               surviving Beneficiaries of the same class, unless
                               the Owner directs otherwise. If there is no
                               surviving Beneficiary in a particular class (e.g.
                               1st Contingent Beneficiary, see Specifications
                               page), the benefit is divided equally among the
                               surviving Beneficiaries of the next class. If
                               there is no surviving Beneficiary, the deceased
                               Beneficiary's interest will pass to the Owner or
                               the Owner's estate. At the death of the first
                               joint Owner prior to the Annuity Date, the
                               surviving joint Owner is the sole, primary
                               Beneficiary notwithstanding that the designated
                               Beneficiary may be different.

                               The Beneficiary can not assign, transfer,
                               commute, anticipate or encumber the proceeds or
                               payments unless given that right by the Owner.

Protection of Proceeds         To the extent allowed by law, this
                               contract and any payments made under it will be
                               exempt from the claims of creditors.

                               PAYMENTS

Payments                       Each Payment is equal to the gross payment less
                               the amount of any applicable premium tax. The
                               Company reserves the right to deduct the amount
                               of the premium tax from the Accumulated Value at
                               a later date rather than when the premium tax
                               liability is first incurred by the Company. In no
                               event will an amount be deducted for premium
                               taxes before the Company has incurred a tax
                               liability under applicable State law.

Initial Payment                The Initial Payment is shown on the
                               Specifications page.

Additional Payments            Prior to the Annuity Date and before the
                               death of an Owner, the Owner may make additional
                               Payments of at least the Minimum Additional
                               Payment Amount (see Specifications page). Total
                               Payments made may not exceed $5,000,000 without
                               the Company's consent.

Payment Allocations            If the applicable refund amount
                               (outlined in the Right to Examine Contract
                               provision, see page 1) provides for a refund of:

                                     (a)  gross payments, or

                                     (b)  the greater of the Accumulated Value,
                                          after application of any Market Value
                                          Adjustment, plus any fees or other
                                          charges imposed or gross payments,

                               then the Initial Payment and any subsequent
                               Payment made during the contract's first fifteen
                               days, allocated to the Sub-Accounts, will be
                               allocated to the money market Sub-Account. After
                               the first fifteen days, such amounts will be
                               allocated in accordance with the Payment
                               Allocation, shown on the Specifications page. New
                               Payments made after the first fifteen days will
                               be allocated in accordance with the Payment
                               Allocation shown on the Specifications Page
                               unless allocation instructions accompany the
                               Payment or the Payment Allocation is changed by
                               the Owner.

                               If the applicable refund amount provides
                               otherwise, the Initial Payment will be allocated
                               in accordance with the Payment Allocation, shown
                               on the Specifications page. Each subsequent
                               Payment will be allocated in the same manner
                               unless allocation instructions accompany the
                               Payment or the Payment Allocation is changed by
                               the Owner.

                               The minimum amount that may be allocated to the
                               Guarantee Period Account is shown on the
                               Specifications page. If the Owner requests an
                               allocation less than the minimum amount, the
                               Company reserves the right to apply that amount
                               to the money market Sub-Account.

                               VALUES

Value of the Variable          The value of a Sub-Account on a Valuation Date is
Account                        determined by multiplying the Accumulation Units
                               in that Sub-Account by the Accumulation Unit
                               Value as of the Valuation Date.

                               Accumulation Units are purchased when an amount
                               is allocated to a Sub-Account. The number of
                               Accumulation Units purchased equals that amount
                               divided by the applicable Accumulation Unit Value
                               as of the Valuation Date.

Accumulation Unit              The value of a Sub-Account Accumulation Unit
Values                         as of any Valuation Date is determined by
                               multiplying the value of an Accumulation Unit
                               for the preceding Valuation Date by the Net
                               Investment Factor for that Valuation Period.

Net Investment Factor          The Net Investment Factor measures the investment
                               performance of a Sub-Account from one Valuation
                               Period to the next. This factor is equal to
                               1.000000 plus the result (which may be positive
                               or negative) from dividing (a) by (b) and
                               subtracting (c) and (d) where:

                                   (a)  is the investment income of a
                                        Sub-Account for the Valuation Period,
                                        including realized or unrealized
                                        capital gains and losses during the
                                        Valuation Period, adjusted for
                                        provisions made for taxes, if any;

                                   (b)  is the value of that Sub-Account's
                                        assets at the beginning of the
                                        Valuation Period;

                                   (c)  is the Mortality and Expense Risk Charge
                                        applicable to the current Valuation
                                        Period plus any applicable Rider
                                        charges (see Specifications page); and

                                   (d)  is the Administrative Charge applicable
                                        to the current Valuation Period (see
                                        Specifications page).

                               The Company assumes the risk that its actual
                               mortality expense experience may exceed the
                               amounts provided under the contract. The Company
                               guarantees that the charge for mortality and
                               expense risks and the administrative charge will
                               not be increased. Subject to applicable State and
                               federal laws, these charges may be decreased or
                               the method used to determine the Net Investment
                               Factor may be changed.

Value of the Fixed             Amounts allocated to the Fixed Account receive
Account                        interest at rates periodically set by the
                               Company.  The Company guarantees that the initial
                               rate of interest in effect when an amount is
                               allocated to the Fixed Account will remain in
                               effect for that amount for one year or until such
                               amount is transferred out of the Fixed Account,
                               whichever is sooner. Thereafter, the rate of
                               interest for that amount will be the Company's
                               current interest rate, but no less than the
                               Minimum Fixed Account Guaranteed Interest Rate
                               (see Specifications page).

                               The value of the Fixed Account on any date is the
                               sum of amounts allocated to the Fixed Account
                               plus interest compounded and credited daily at
                               the rates applicable to those amounts. The
                               value of the Fixed Account will be at least
                               equal to the minimum required by law in the
                               State in which this contract is delivered.

Value of the Guarantee     Amounts allocated to the same Guarantee Period
Period Accounts            Account on the same day will be treated as one
                           Guarantee Period Account. The interest rate in
                           effect when an amount is allocated to a Guarantee
                           Period Account is guaranteed for the duration of
                           the Guarantee Period. Each time the Guaranteed
                           Interest Rate changes for a particular Guarantee
                           Period, a new Guarantee Period Account is
                           established.

                           The value of a Guarantee Period Account on any
                           date is the sum of amounts allocated to that
                           Guarantee Period Account plus interest compounded
                           and credited daily at the rate applicable to that
                           amount.

Guaranteed Interest        The Company will periodically set Guaranteed Interest
Rates                      Rates for each available Guaranteed Period. These
                           rates will be guaranteed for the duration of the
                           respective Guarantee Periods.  A Guaranteed Interest
                           Rate will never be less than the Guarantee Period
                           Account Minimum Interest Rate (see Specifications
                           page).

Renewal Guarantee          At least 45 days (but not more than 75 days) prior
Periods                    to the end of a Guarantee Period, the Company will
                           notify the Owner in writing of the expiration of that
                           Guarantee Period. The Owner may transfer amounts
                           to the Sub-Accounts, the Fixed Account or establish a
                           new Guarantee Period Account of any duration then
                           offered by the Company as of the day following
                           the expiration of the Guarantee Period. The
                           transfer will not be subject to a Market Value
                           Adjustment; see "Market Value Adjustment"
                           provision. Guaranteed Interest Rates
                           corresponding to the available Guarantee Periods
                           may be higher or lower than the previous
                           Guaranteed Interest Rate. If reallocation
                           instructions are not received at the Principal
                           Office before the end of a Guarantee Period, the
                           Guarantee Period Account value will be
                           automatically applied to a new Guarantee Period
                           Account with the same Guarantee Period unless:

                               (a)       the Guarantee Period Account value is
                                         less than the Guarantee Period Account
                                         Minimum Allocation Amount (see
                                         Specifications page) on its expiration
                                         date; or

                               (b)       the Guarantee Period would extend
                                         beyond the Annuity Date or is no
                                         longer available.

                            In such cases, the Guarantee Period Account value
                            will be transferred to the money market
                            Sub-Account.

Contract Fee                Prior to the Annuity Date, on each Contract
                            Anniversary, and when the Contract is surrendered,
                            the Company will deduct a Contract Fee (see
                            Specifications page) Pro Rata.

                            TRANSFER

                            Prior to the Annuity Date, the Owner may transfer
                            amounts among accounts by Request to the Principal
                            Office. Transfers to a Guarantee Period Account
                            must be at least equal to the Guarantee Period
                            Account Minimum Allocation Amount (see
                            Specifications page). If the Owner requests the
                            transfer of a smaller amount to the Guarantee
                            Period Account, the Company may transfer that
                            amount to the money market Sub-Account.

<Page>

                              Any transfer from a Guarantee Period Account prior
                              to the end of its Guarantee Period will be subject
                              to a Market Value Adjustment.

                              There is no charge for the first twelve transfers
                              per contract year. A transfer charge of up to $25
                              may be imposed on each additional transfer.

                              The Company reserves the right to limit or refuse
                              transfers if it determines, in its sole
                              discretion, that the exercise of that right by an
                              Owner(s), or any agent or duly authorized
                              representative of such Owner(s) is, or would be,
                              to the disadvantage of other Owners. Such transfer
                              limitations could be applied to transfers to or
                              from some or all of the accounts and could include
                              but not be limited to:

                                 (a)    the requirement of a minimum time
                                        period between each transfer;

                                 (b)    not accepting a transfer request of an
                                        agent or duly authorized representative
                                        of such Owner(s) authorized to act on
                                        behalf of such Owner(s); and

                                 (c)    limiting the dollar amount that may be
                                        transferred to or from any of the
                                        accounts by an Owner(s) at any one time.

                              Such limitations, individually or in aggregate,
                              may be applied in any manner reasonably designed
                              to prevent any use of the transfer right which is
                              considered by the Company to be to the
                              disadvantage of other Owners.

                              WITHDRAWAL AND SURRENDER

                              Prior to the Annuity Date, the Owner may, by
                              Request, withdraw a part of the Surrender Value or
                              surrender the contract for its Surrender Value.

                              Any withdrawal must be at least the Minimum
                              Withdrawal Amount (see Specification page). A
                              withdrawal will not be permitted if the
                              Accumulated Value remaining in the contract would
                              be less than the Minimum Accumulated Value After
                              Withdrawal (see Specifications page). The Request
                              must indicate the accounts from which it is to be
                              withdrawn. A withdrawal from a Guarantee Period
                              Account will be subject to a Market Value
                              Adjustment.

                              When surrendered, this contract terminates and the
                              Company has no further liability under it. The
                              Surrender Value will be based on the Accumulated
                              Value on the Effective Valuation Date.

                              Amounts taken from the Variable Account will be
                              paid within 7 days of the date a Request is
                              received. The Company reserves the right to delay
                              payments subject to applicable laws, rules and
                              regulations governing variable annuities.

                              Amounts taken from the Fixed Account or the
                              Guarantee Period Accounts will normally be paid
                              within 7 days of the date a Request is received.
                              The Company may defer payment for up to six months
                              from the receipt date.

                              If deferred for 30 days or more, the amount
                              payable will be credited interest at a rate of at
                              least 3% or the rate mandated by the State.

Market Value Adjustment       A transfer, withdrawal or surrender from a
                              Guarantee Period Account after the expiration of
                              its Guarantee Period will not be subject to a
                              Market Value Adjustment. A Market Value Adjustment
                              will apply to all other transfers, withdrawals, or
                              surrenders from a Guarantee Period Account.
                              Amounts in a Guarantee Period Account that are
                              applied under an Annuity Option are treated as
                              withdrawals and a Market Value Adjustment may
                              apply. The Market Value Adjustment will be
                              determined by multiplying the amount taken from
                              each Guarantee Period Account by the market value
                              factor. The market value factor for each Guarantee
                              Period Account is equal to:

                                                           n/365
                                          [(1 + i)/(1 + j)]      - 1

                              where:

                                        i - is the Guaranteed Interest Rate
                                        expressed as a decimal (for example: 3%
                                        = 0.03) being credited to the current
                                        Guarantee Period;

                                        j - is the new Guaranteed Interest Rate
                                        (as adjusted due to selection of any
                                        rider, if applicable), expressed as a
                                        decimal, for a Guarantee Period with a
                                        duration equal to the number of years
                                        remaining in the current Guarantee
                                        Period, rounded to the next higher
                                        number of whole years. If that rate is
                                        not available, the Company will use a
                                        suitable rate or index allowed by the
                                        Department of Insurance; and

                                        n - is the number of days remaining from
                                        the Effective Valuation Date to the end
                                        of the current Guarantee Period.

                              If the Guaranteed Interest Rate being credited is
                              lower than the new Guaranteed Interest Rate, the
                              Market Value Adjustment will decrease the
                              Guarantee Period Account value. Similarly, if the
                              Guaranteed Interest Rate being credited is higher
                              than the new Guaranteed Interest Rate, the Market
                              Value Adjustment will increase the Guarantee
                              Period Account value. The Market Value Adjustment
                              will never result in a change to the value more
                              than the interest earned in excess of an amount
                              based on the Guarantee Period Account Minimum
                              Interest Rate (see Specifications page).

                              DEATH BENEFIT

                              At the death of an Owner prior to the Annuity
                              Date, the Company will pay to the Beneficiary a
                              Death Benefit upon receipt at the Principal Office
                              of Proof of Death. If the Owner is a non-natural
                              person, prior to the Annuity Date a Death Benefit
                              is paid on the death of an Annuitant, upon receipt
                              at the Principal Office of Proof of Death.

Death Benefit                 The Death Benefit will be the greater of:

                                   (a)  the Accumulated Value on the
                                        Effective Valuation Date,
                                        increased by any positive
                                        Market Value Adjustment; or

                                   (b)  the sum of the gross payments
                                        made under this contract prior
                                        to the date of death,
                                        proportionately reduced to
                                        reflect all partial
                                        withdrawals.

                                        For each withdrawal, the proportionate
                                        reduction is calculated by multiplying
                                        the Death Benefit under (b), immediately
                                        prior to the withdrawal, by the
                                        following:


                                           Amount of the withdrawal
                                           ------------------------
                                        Accumulated Value immediately prior
                                                 to the withdrawal

Payment of the                 Unless the Owner has specified otherwise, the
Death Benefit                  Death Benefit will be paid to the Beneficiary
                               within 7 days of the Effective Valuation Date.
                               Alternatively, the Beneficiary may, by a
                               Request in writing, elect to:

                                      (a) defer distribution of the Death
                                          Benefit for a period no more than
                                          5 years from the date of death; or

                                      (b) receive distributions over his/her
                                          life expectancy (or over a period not
                                          extending beyond such life
                                          expectancy). Distributions must begin
                                          within one year from the date of
                                          death.

                               If distribution of the Death Benefit is deferred
                               under (a) or (b), any value in the Guarantee
                               Period Accounts will be transferred to the money
                               market Sub-Account. The excess, if any, of the
                               Death Benefit over the Accumulated Value will
                               also be transferred to the money market
                               Sub-Account. The Beneficiary may, by Request,
                               effect transfers and withdrawals, but may not
                               make additional Payments. If there are multiple
                               Beneficiaries, the consent of all is required.

                               If the sole Beneficiary is the deceased Owner's
                               spouse, the Beneficiary may, by a Request in
                               writing, continue the contract and become the new
                               Owner and Annuitant subject to the following:

                                      (a) any value in the Guarantee
                                          Period Accounts will be
                                          transferred to the money
                                          market Sub-Account;

                                      (b) the excess, if any, of the
                                          Death Benefit over the
                                          contract's Accumulated Value
                                          will also be transferred to
                                          the money market Sub-Account;

                                      (c) additional Payments may be
                                          made; and

                                      (d) any subsequent spouse of the
                                          new Owner, if named as the
                                          Beneficiary, may not continue
                                          the contract.

                               THE PAYOUT PHASE

                               ANNUITY BENEFIT

Annuity  Options               Annuity Options are available on a fixed,
                               variable or combination fixed and variable basis.
                               The Annuity Options described below or any
                               alternative option offered by the Company may be
                               chosen. If no option is chosen, monthly benefit
                               payments will be made under the Life Annuity with
                               Cash Back option.

                               The Owner may also elect to have the Death
                               Benefit applied under any Annuity Option not
                               extending beyond the Beneficiary's life
                               expectancy. Such an election may not be altered
                               by the Beneficiary.

                               Fixed annuity options are funded through the
                               General Account. Variable annuity options may be
                               funded through one or more of the Sub-Accounts.
                               Not all Sub-Accounts may be available.

Selection of Annuity           The Owner must select an Annuity Benefit Payment
Benefit Payments               Option. Annuity benefit payments will be paid
                               monthly or at any other frequency currently
                               offered by the Company. If the first payment
                               would be less than the Minimum Annuity Benefit
                               Payment (see Specifications page), a single
                               payment will be made instead. If a life annuity
                               option has been elected, satisfactory proof of
                               the date of birth of the Annuitant must be
                               received at the Principal Office before any
                               payment is made. Also, if a life annuity option
                               has been elected, the Company may require from
                               time to time satisfactory proof that the
                               Annuitant is alive.

Annuity Benefit                In the case of a variable annuity option, the
Payment Change                 Owner must select an Annuity Benefit Payment
Frequency                      Change Frequency. This is the frequency of
                               change in the dollar value of the variable
                               portion of the annuity benefit payments. For
                               example, if an annual Annuity Benefit Payment
                               Change Frequency is chosen, the dollar value
                               of variable annuity benefit payments will
                               remain constant within each one-year period.
                               The Owner must also select the date of the
                               first change.

Assumed Investment             In the case of a variable annuity option, the
Return                         Owner must select an Assumed Investment Return
                               ("AIR"), from the options currently made
                               available by the Company.  This rate is used to
                               determine the initial variable annuity benefit
                               payment and how the payment will change over
                               time in response to the performance
                               of the selected Sub-Accounts. If the actual
                               performance of any selected Sub-Account (as
                               measured by the Net Investment Factor) is equal
                               to the AIR, the annuity benefit payment
                               attributable to that Sub-Account will be
                               constant. If the actual performance is greater
                               than the AIR, the annuity benefit payment will
                               increase. If the actual performance is less than
                               the AIR, the annuity benefit payment will
                               decrease.

Reversal of Decision           The Owner may reverse the decision to annuitize
To Annuitize                   by a Request in writing within 90 days after
                               the Annuity Date. Upon receipt of such notice,
                               the Company will place the contract back to the
                               Accumulation Phase subject to the following:

                                     (a)  The funds applied under a variable
                                          annuity option during this period will
                                          be treated as if they had been
                                          invested in the Accumulation Phase of
                                          the contract, with the same
                                          allocations that were in effect since
                                          the Annuity Date.

                                     (b)  The funds applied under a fixed
                                          annuity option during this period will
                                          be treated as if they had been
                                          invested in the Accumulation Phase of
                                          the contract in the Fixed Account,
                                          since the Annuity Date.

                                     (c)  Any annuity benefit payment paid or
                                          withdrawal taken during this period
                                          will be treated as a withdrawal of the
                                          Surrender Value as of the date of the
                                          payment or withdrawal. Fixed annuity
                                          benefit payments will be treated as
                                          withdrawals from the Fixed Account.
                                          Variable annuity benefit payments will
                                          be treated as withdrawals from the
                                          variable Sub-Accounts.

                                     (d)  If the Company learns of the Owner's
                                          decision to reverse after the Maximum
                                          Alternate Annuity Date (see
                                          Specifications page). The Owner must
                                          immediately select another Annuity
                                          Benefit Payment Option.

Annuity Value                  The Annuity Value will be the Accumulated Value,
                               after application of any Market Value Adjustment,
                               less any applicable premium tax.  For a Death
                               Benefit annuity, the Annuity Value will be the
                               amount of the Death Benefit, less any applicable
                               premium tax. The Annuity Value applied under a
                               variable Annuity Option is based on the
                               Accumulation Unit Value on a Valuation Date not
                               more than four weeks, uniformly applied,
                               before the Annuity Date.

                               The amount of the first annuity benefit payment
                               under all available options, except the payments
                               guaranteed for a specified number of years
                               option, will depend on the age and/or sex of the
                               Annuitant on the Annuity Date and the Annuity
                               Value applied. The payments guaranteed for a
                               specified number of years option is based only on
                               the duration of payments and the Annuity Value.

Annuity Unit Values            A Sub-Account Annuity Unit Value on any
                               Valuation Date is equal to its value on the
                               preceding Valuation Date multiplied by the
                               product of:

                                     (a)  a discount factor equivalent to the
                                          Assumed Investment Return; and

                                     (b)  the Net Investment Factor of the
                                          Sub-Account funding the annuity
                                          benefit payments for the applicable
                                          Valuation Period.

                               The value of an Annuity Unit as of any date other
                               than a Valuation Date is equal to its value as of
                               the preceding Valuation Date.

                               Each variable annuity benefit payment is equal to
                               the number of Annuity Units multiplied by the
                               applicable value of an Annuity Unit, except that
                               under a Joint and Survivor Option, after the
                               first death, the number of units in each payment
                               is equal to the total number of units multiplied
                               by the Survivor Annuity Benefit Percentage.

                               Variable annuity benefit payments will increase
                               or decrease with the value of the Annuity Units
                               as of the date of the first payment of each
                               Annuity Benefit Payment Change Frequency. The
                               Company guarantees that the amount of each
                               variable annuity benefit payment will not be
                               affected by changes in mortality and expense
                               experience.

Number of Annuity              For each Sub-Account the number of Annuity Units
Units                          determining the benefit payable is equal to
                               the amount of the first annuity benefit payment
                               divided by the value of the Annuity Unit as of
                               the Valuation Date used to calculate the amount
                               of the first payment. Once annuity benefit
                               payments begin, the number of  Annuity Units will
                               not change unless a split, a withdrawal or a
                               transfer is made.

Payment of Annuity             Annuity Benefit Payments are paid to the Owner.
Benefit Payments               By Request in writing, the Owner may direct
                               that payments are made to another person,
                               persons or entity.  If an Owner, who is not
                               also an Annuitant, dies on or after the Annuity
                               Date, the following occurs:

                                     (a)  If the deceased Owner was the sole
                                          Owner, then the remaining annuity
                                          benefit payments will be payable to
                                          the Beneficiary in accordance with the
                                          terms of the Annuity Option selected.
                                          Upon the death of a sole Owner, the
                                          Beneficiary becomes the Owner of the
                                          contract.

                                     (b)  If the contract has joint Owners, then
                                          the remaining annuity benefit payments
                                          will be payable to the surviving joint
                                          Owner in accordance with the terms of
                                          the Annuity Option selected. Upon the
                                          death of the surviving joint Owner,
                                          the Beneficiary becomes the Owner of
                                          the contract.

                               TRANSFER

                               After the Annuity Date and prior to the death of
                               the Annuitant, the Owner may transfer among
                               Sub-accounts by Request to the Principal Office.

                               Transfers may increase or decrease the number of
                               Annuity Units in each subsequent payment.

                               There is no charge for the first twelve transfers
                               per contract year. A transfer charge of up to $25
                               may be imposed on each additional transfer.

                               The Company reserves the right to limit or refuse
                               transfers if it determines, in its sole
                               discretion, that the exercise of that right by an
                               Owner(s), or any agent or duly authorized
                               representative of such Owner(s) is, or would be,
                               to the disadvantage of other Owners. Such
                               transfer limitations could be applied to
                               transfers to or from some or all of the accounts
                               and could include but not be limited to:

                                     (a)  the requirement of a minimum time
                                          period between each transfer;

                                     (b)  not accepting a transfer request of
                                          an agent or duly authorized
                                          representative of such Owner(s)
                                          authorized to act on behalf of such
                                          Owner(s); and

                                     (c)  limiting the dollar amount that may
                                          be transferred to or from any of the
                                          accounts by an Owner(s) at any
                                          one time.

                               Such limitations, individually or in aggregate,
                               may be applied in any manner reasonably designed
                               to prevent any use of the transfer right which
                               is considered by the Company to be to the
                               disadvantage of other Owners.

                               WITHDRAWAL

                               After the Annuity Date and prior to the death of
                               the Annuitant, the Owner may have the right,
                               based on the Annuity Option selected, to make
                               withdrawals. If the Death Benefit is applied
                               under an Annuity Option the Beneficiary may also
                               make withdrawals in accordance with this
                               provision.

                               Amounts withdrawn that were applied under a
                               variable Annuity Option will be paid within 7
                               days of the date a Request is received. The
                               Company reserves the right to delay payments
                               subject to applicable laws, rules and regulations
                               governing variable annuities.

                               Amounts withdrawn that were applied under a fixed
                               Annuity Option will normally be paid within 7
                               days of the date a Request is received. The
                               Company may defer payment for up to six months
                               from the date a Request is received. If deferred
                               for 30 days or more, the amount payable will be
                               credited interest at a rate of at least 3% or the
                               appropriate rate mandated by the State.

                               Only one Request for withdrawal under each
                               provision may be made each calendar year, unless
                               a payments guaranteed for a specified number of
                               years option is chosen.

Payment Withdrawal             Each calendar year, the Owner can request up to
Amount Option                  an amount equal to the Payment Withdrawal Amount
                               (see Specifications page) multiplied by the
                               previous monthly annuity benefit payment.

                               For fixed Annuity Options, each withdrawal
                               proportionately reduces the dollar amount of each
                               future annuity benefit payment. The proportionate
                               reduction is calculated by multiplying the dollar
                               amount of each future annuity benefit payment by
                               the following:

                                          Amount of the withdrawal
                                          ------------------------
                                   Present Value of all remaining fixed annuity
                                     benefit payments immediately prior the
                                                 withdrawal.

                               For variable Annuity Options, each withdrawal
                               proportionately reduces the number of Annuity
                               Units in each future annuity benefit payment. The
                               proportionate reduction is calculated by
                               multiplying the number of Annuity Units in each
                               future annuity benefit payment by the following:

                                          Amount of the withdrawal
                                          ------------------------
                                   Present Value of all remaining variable
                                  annuity benefit payments immediately prior
                                             to the withdrawal.

Present Value                  Over the life of the contract, for payments
Withdrawal Option              guaranteed for a specified number of years,
                               life with payments guaranteed for a specified
                               number of years and life with cash back
                               Annuity Options when there are remaining
                               guaranteed payments, the Owner may request
                               withdrawals which represent a percentage of the
                               Present Value of those remaining guaranteed
                               annuity benefit payments. Each year a withdrawal
                               is taken under this provision, the Company
                               records the percentage withdrawn. Each withdrawal
                               proportionately reduces future annuity benefit
                               payments.  (See

Form A3036-01                         22                                 BACS11

                               proportionate reduction calculation below.) The
                               total percentage withdrawn over the life of the
                               contract cannot exceed the Present Value
                               Withdrawal Amount (see Specifications page).

                               For fixed Annuity Options, each withdrawal
                               proportionately reduces the dollar amount of each
                               future guaranteed annuity benefit payment. The
                               proportionate reduction is calculated by
                               multiplying the dollar amount of each future
                               guaranteed annuity benefit payment by the
                               following:

                                        Amount of the withdrawal
                                        ------------------------
                                    Present Value of all remaining fixed
                                     guaranteed annuity benefit payments
                                    immediately prior to the withdrawal.

                               For variable Annuity Options, each withdrawal
                               proportionately reduces any remaining guaranteed
                               payments. The proportionate reduction is
                               calculated by multiplying the number of Annuity
                               Units in each future guaranteed annuity benefit
                               payment by the following:

                                        Amount of the withdrawal
                                        ------------------------
                                   Present Value of all remaining variable
                                     guaranteed annuity benefit payments
                                     immediately prior to the withdrawal.

                               If an Annuitant is still living after there are
                               no remaining guaranteed payments under a life
                               with payments guaranteed for a specified number
                               of years or life with cash back Annuity Option:

                                     (a)  for variable Annuity Options, the
                                          number of Annuity Units will increase
                                          to the number of Annuity Units payable
                                          prior to any withdrawals, adjusted for
                                          transfers.

                                     (b)  for fixed Annuity Options, the dollar
                                          amount of the annuity benefit payments
                                          will increase to the amount payable
                                          prior to any withdrawals, adjusted for
                                          transfers.

                               PRESENT VALUE OF ANNUITY BENEFIT PAYMENTS

                               For a variety of purposes, it is at times
                               necessary to determine the Present Value of
                               either all future annuity benefit payments or of
                               future guaranteed annuity benefit payments.
                               Present Values are calculated based on the
                               Annuity 2000 Mortality Table, male, female or
                               unisex rates as appropriate, and the interest
                               rate or AIR used to determine the annuity benefit
                               payments.

                               DEATH OF THE ANNUITANT

                               Unless otherwise indicated by the Owner, upon the
                               death of the Annuitant, the Present Value of the
                               remaining guaranteed annuity benefit payments may
                               be paid to the Owner.

                               LIFE ANNUITY:

                                        The annuity benefit payments do not
                                        continue after the death of the

                                        the survivor is equal to the total

                                        Survivor Annuity Benefit Percentage.

                                        the survivor is equal to the dollar
                                        value of each payment paid prior to such
                                        death multiplied by the Survivor
                                        Annuity Benefit Percentage.

                               be paid to the Owner or Beneficiary, whichever is

                               this contract. Agents or Brokers are not

Incontestability               The Company cannot challenge the validity of this
                               contract after it has been in force for more than
                               two years from the date of issue.

                               request must be received by the Principal
                               Office at least one month before the new Annuity
                               Date. To the extent permitted by applicable laws,
                               rules and regulations governing variable
                               annuities, the new Annuity Date must be no later
                               than the Maximum Alternative Annuity Date shown
                               on the Specifications page.

                               contract equal or exceed those required by the
                               State in which the contract is delivered.

Annual Report                  The Company will furnish an annual report
                               to the Owner containing a statement of the number
                               and value of Accumulation Units credited to the
                               Sub-Accounts, the value of the Fixed Account and
                               the Guarantee Period Accounts and any other
                               information required by applicable law, rules and
                               regulations.

Addition, Deletion, or         The Company reserves the right, subject to
Substitution of                compliance with applicable law, to add to,
Investments                    delete from, or substitute for the shares of a
                               Fund that are held by the Sub-Accounts or
                               that the Sub-Accounts may purchase. The Company
                               also reserves the right to eliminate the shares
                               of any Fund no longer available for investment
                               or if the Company believes further investment
                               in the Fund is no longer appropriate for the
                               purposes of the Sub-Accounts. The Company
                               will not substitute shares attributable to
                               any interest in a Sub-Account without notice
                               to the Owner and prior approval of the Securities
                               and Exchange Commission as required by the
                               Investment Company Act of 1940. This will not
                               prevent the Variable Account from purchasing
                               other securities for other series or classes of
                               contracts, or from permitting a conversion
                               between series or classes of contracts on the
                               basis of requests made by Owners.

                               In addition, the Company reserves the right,
                               subject to compliance with applicable laws, to
                               establish additional Separate Accounts, Guarantee
                               Period Accounts and Sub-Accounts and to make them
                               available to any class or series of contracts as
                               the Company considers appropriate. Each new
                               Separate Account or Sub-Account will

                               invest in a new investment company, or in shares
                               of another open-end investment company, or such
                               other investments as may be permitted under
                               applicable law. The Company also reserves the
                               right to eliminate or combine existing
                               Sub-Accounts and to transfer the assets of any
                               Sub-Accounts to any other Sub-Accounts. In the
                               event of any substitution or change, the Company
                               may, by appropriate notice, make such changes in
                               this and other contracts as may be necessary or
                               appropriate to reflect the substitution or
                               change. If the Company considers it to be in the
                               best interest of the owners, the Variable Account
                               or any Sub-Account may be operated as a
                               management company under the Investment Company
                               Act of 1940 or in any other form permitted by
                               law, or may be de-registered under the Act in the
                               event registration is no longer required, or may
                               be combined with other accounts of the Company.

Changes in Law                 The Company reserves the right to make any
                               changes to provisions of the contract to comply
                               with, or give Owners the benefit of, any federal
                               or State statute, rule, or regulations.

Change of Name                 Subject to compliance with applicable law,
                               the Company reserves the right to change the
                               names of the Variable Account or the
                               Sub-Accounts.

Federal Tax                    The Variable Account is not currently subject
Considerations                 to tax, but the Company reserves the right
                               to assess a charge for taxes if the Variable
                               Account becomes subject to tax.

Splitting of Units             The Company reserves the right to split
                               the value of a unit, either to increase or to
                               decrease the number of units. Any splitting of
                               units will have no material effect on the
                               benefits, provisions or investment return of this
                               contract or upon the Owner, the Annuitant, any
                               Beneficiary, or the Company.

Account                        assets is determined separately from the other
                               assets of the Company. The assets of a Separate
