                     ANCHOR NATIONAL LIFE INSURANCE COMPANY

                    INDIVIDUAL RETIREMENT ANNUITY ENDORSEMENT

This Endorsement amends the Certificate to which it is attached so that it may
qualify as an Individual Retirement Annuity (IRA) under Section 408(b) of the
Internal Revenue Code (Code) and the Regulations under that Section. The
endorsement may be amended from time to time to comply with changes in the
Internal Revenue Code. The Participant has the right to refuse to accept any
such amendment; however, we shall not be held liable for any tax consequences
incurred by the Participant as a result of such refusal. In the case of a
conflict with any provision in the Certificate, the provisions of this
Endorsement will control. The effective date of this Endorsement is the
Certificate Date shown on the Certificate Data Page. The Certificate is amended
as follows:

1.   The Participant, Annuitant and Payee shall be the same individual. The
     Participant, Annuitant and Payee cannot be changed, except as otherwise
     permitted under the IRC and applicable regulations. All distributions made
     while the Participant is alive must be made to the Participant.

2.   The interest of the Participant under this Certificate shall be
     nonforfeitable except as provided by law.

3.   The Certificate may not be sold, assigned, discounted, pledged as
     collateral for a loan or as security for the performance of any obligation
     or for any other purpose, or otherwise transferred (other than a transfer
     incident to a divorce or separation instrument in accordance with Section
     408(d)(6) of the Code) to any person other than to the Company.

4.   This Certificate is established for the exclusive benefit of the
     Participant and his or her Beneficiary(ies).

5.   Except in the case of a rollover contribution (as permitted by Code
     Sections 402(c), 403(a)(4), 403(b)(8), or 408(d)(3)), or a contribution
     made in accordance with the terms of a Simplified Employee Pension (SEP) as
     described in Code Section 408(k), or a nontaxable transfer from an
     individual retirement account under 408(a) of the Code or another IRA under
     Section 408(b) of the Code, contributions shall not exceed $2,000 for any
     taxable year. All contributions must be in cash.

     Any refund of premiums (other than those attributable to excess
     contributions) will be applied, before the close of the calendar year
     following the year of the refund, toward the payment of future premiums or
     the purchase of additional benefits.

     No contribution will be accepted under a SIMPLE IRA plan established by any
     employer pursuant to Code section 408(p). No transfer or rollover of funds
     attributable to contributions made by a particular employer under its
     SIMPLE IRA plan will be accepted from a SIMPLE IRA, that is, an IRA used in
     conjunction with a SIMPLE IRA plan, prior to the expiration of the 2-year
     period beginning on the date the individual first participated in that
     employer's SIMPLE IRA plan.

6.   Unless otherwise permitted under applicable law, the Participant's entire
     interest in the Certificate shall be distributed no later than the
     "required beginning date," or commence to be distributed beginning no later
     than the "required beginning date," over

     (a)  the life of the Participant, or the lives of the Participant and his
          or her designated Beneficiary (within the meaning of section 401(a) of
          the Code), or

     (b)  a period certain not extending beyond the life expectancy of the
          Participant, or the joint and last survivor expectancy of the
          Participant and his or her Beneficiary as required by law.

     As used in this Endorsement, the term "required beginning date" means April
     1 of the calendar year following the calendar year in which the Participant
     attains age 70 1/2, or such later date provided by law.

     Payments must be made in periodic payments at intervals of no longer than
     one year. In addition, 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.

     If the Participant's interest is to be distributed over a period greater
     than one year, the amount to be distributed by December 31 of each year
     (including the year in which the required beginning date occurs) will be
     made in accordance with the requirements of Code Section 401(a)(9),
     including the incidental death benefit requirements of Code Section
     401(a)(9)(G), and the regulations thereunder, including the minimum
     distribution incidental benefit requirement of Code Section 1.401(a)(9)-2
     of the Proposed Income Tax Regulations.

     Life expectancy is computed by use of the expected return multiples in
     Tables V and VI of Section 1.72-9 of the Income Tax Regulations. Unless
     otherwise elected by the Participant by the time distributions are required
     to begin, life expectancies shall be recalculated annually. Such election
     shall be irrevocable by the Participant and shall apply to all subsequent
     years. The life expectancy of a non-spouse designated Beneficiary may not
     be recalculated. Instead, life expectancy will be calculated using the
     attained age of such designated Beneficiary during the calendar year in
     which the Participant attains age 70 1/2, and payments for subsequent years
     shall be calculated based on such life expectancy reduced by one for each
     calendar year which has elapsed since the calendar year life expectancy was
     first calculated. Life expectancy for distributions under an Annuity
     Payment Option may not be recalculated.

7.   Unless otherwise permitted under applicable law, upon the death of the
     Participant:

     (a)  if the Participant dies on or after the required beginning date (or if
          distributions have begun before the required beginning date as
          irrevocable annuity payments or


                                       2
<PAGE>   3

          Income Payments, whichever term is applicable), the remaining portion
          of the Participant's interest (if any) shall be distributed at least
          as rapidly as under the method of distribution in effect as of the
          Participant's death;

     (b)  if the Participant dies before the required beginning date and an
          irrevocable annuity distribution has not begun, the entire interest
          will be distributed by December 31 of the calendar year which contains
          the fifth anniversary of the Participant's death except that:

          (1)  if the interest is payable to an individual who is the
               Participant's designated Beneficiary, the designated Beneficiary
               may elect to receive the entire interest over the life of the
               designated Beneficiary or over a period not extending beyond the
               life expectancy of the designated Beneficiary, commencing on or
               before December 31 of the calendar year immediately following the
               calendar year in which the Participant died; or

          (2)  if the designated Beneficiary is the Participant's surviving
               spouse, the surviving spouse may elect to receive the entire
               interest over the life of the surviving spouse or over a period
               not extending beyond the life expectancy of the surviving spouse,
               commencing at any date on or before the later of (A) December 31
               of the calendar year immediately following the calendar year in
               which the Participant died or (B) December 31 of the calendar
               year in which the Participant would have attained age 70 1/2. If
               the surviving spouse dies before distributions begin, the
               limitations of this paragraph 7 (without regard to this paragraph
               (b)) will be applied as if the surviving spouse were the
               Participant.

               An irrevocable election of the method of distribution by a
               designated Beneficiary who is the surviving spouse 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 this
               paragraph (b).

          (3)  if the designated Beneficiary is the Participant's surviving
               spouse, the spouse may irrevocably elect to treat the Certificate
               as his or her own IRA. This election will be deemed to have been
               made if such surviving spouse, subject to the requirements of
               Section 5 of this Endorsement, (i) makes a regular IRA
               contribution to the Certificate, (ii) makes a rollover to or from
               the Certificate, or (iii) fails to elect that his or her interest
               will be distributed in accordance with one of the preceding
               provisions of this paragraph (b).

          An irrevocable election of the method of distribution by a designated
          Beneficiary who is not the surviving spouse must be made no later than
          December 31 of the calendar year immediately following the calendar
          year in which the Participant died. If no such election is made, the
          entire interest will be distributed by


                                       3
<PAGE>   4

          December 31 of the calendar year containing the fifth anniversary of
          the Participant's death.

     Life expectancy is computed by use of the expected return multiples in
     Tables V and VI of Section 1.72-9 of the Income Tax Regulations. For
     purposes of distributions beginning after the Participant's death, unless
     otherwise elected by the surviving spouse by the time distributions are
     required to begin, life expectancies shall be recalculated annually. Such
     election shall be irrevocable by the surviving spouse and shall apply to
     all subsequent years. In the case of any other designated Beneficiary, life
     expectancies shall be calculated using the attained age of such designated
     Beneficiary during the calendar year in which distributions are required to
     begin pursuant to this section, and payments for any subsequent calendar
     year shall be calculated based on such life expectancy reduced by one for
     each calendar year which has elapsed since the calendar year life
     expectancy was first calculated. Life expectancy for distributions under an
     Annuity Payment Option in the Certificate may not be recalculated.

     Distributions under this section are considered to have begun if
     distributions are made on account of the Participant reaching his or her
     required beginning date or if prior to the required beginning date
     distributions irrevocably commence over a period permitted and in an
     annuity form acceptable under Section 1.401(a)(9)-2 of the Proposed Income
     Tax Regulations.

8.   The Company shall furnish annual calendar year reports concerning the
     status of the Certificate.

The following provisions entitled MISSTATEMENT OF AGE, PROOF OF AGE AND SURVIVAL
and the table of Annuity Payment Options apply to Simplified Employee Pension
(SEP) contracts only:

9.   The MISSTATEMENT OF AGE OR SEX section of the Certificate is deleted and
     replaced by the following section entitled MISSTATEMENT OF AGE.

     MISSTATEMENT OF AGE
     If the Age of any Annuitant has been misstated, future annuity payments
     will be adjusted using the correct Age according to Our rates in effect on
     the date that annuity payments were determined. Any overpayment from the
     Fixed Account Options, plus interest at the rate of 4% per year, will be
     deducted from the next payment(s) due. Any underpayment from the Fixed
     Account Options, plus interest at the rate of 4% per year, will be paid in
     full with the next payment due. Any overpayment from the Variable
     Portfolios ("Subaccounts") will be deducted from the next payment(s) due.
     Any underpayment from the Variable Portfolios will be paid in full with the
     next payment due.

10.  The PROOF OF AGE, SEX OR SURVIVAL section of the Certificate is deleted and
     replaced by the following section entitled PROOF OF AGE AND SURVIVAL.


                                       4
<PAGE>   5

     PROOF OF AGE AND SURVIVAL. We may require satisfactory proof of correct age
     at anytime. If any payment under this Certificate depends on the Annuitant
     being alive, we may require satisfactory proof of survival.

11.  Except to the extent Treasury regulations allow us to offer additional
     Annuity Payment Options that are acceptable to us, only Annuity Payment
     Options 1 and 1v, 2 and 2v, 3 and 3v, 4 and 4v, 5 and 5v shall be offered
     unless we consent to the use of an additional option. Under Annuity Payment
     Options 2 and 2v, and 3 and 3v, the designated second person must be either
     the Participant's spouse or an individual who is not more than 10 years
     younger than the Participant. Annuity Payment Options 3 and 3v are not
     available to a Participant and the designated second person where the life
     expectancy of the Participant and such person is less than 10 years. Also,
     Annuity Payment Options 4 and 4v are not available to a Participant where
     the Participant's life expectancy is less than 10 years, and Annuity
     Payment Options 5 and 5v are not available to a Participant where the
     Participant's life expectancy is less than 5 years.

     Any additional Annuity Payment Option under the Certificate must meet the
     requirements of section 408(b) of the Code and applicable regulations. The
     provisions of this Endorsement reflecting the requirements of Code Sections
     401(a)(9) and 408(b) override any additional Annuity Payment Option
     inconsistent with such requirements.

     If a guaranteed or specified period of payments is chosen under an Annuity
     Payment Option, the length of the period must not exceed the shorter of (1)
     the Participant's life expectancy, or if a designated second person is
     named, the joint and last survivor expectancy of the Participant and the
     designated second person, and (2) the applicable maximum period under
     Section 1.401(a)(9)-2 of the Proposed Income Tax Regulations.

12.  If you return the Certificate within 10 days after the Certificate Date,
     the Company will refund the amount of your Purchase Payments, without
     adjustment for such items as sales commissions, administrative expenses,
     and fluctuation in market value for the Valuation Period in which the
     Certificate is received. We reserve the right to allocate your Purchase
     Payment(s) to the Cash Management Subaccount until the end of the 10 day
     period. Thereafter, allocations will be made as shown on the Certificate
     Data Page.

13.  The provisions of this Endorsement are intended to comply with the
     requirements of the Code and applicable regulations for IRAs under Section
     408(b) of the Code. The Company reserves the right to amend the Certificate
     and this Endorsement from time to time, without the Participant's consent,
     when such amendment is necessary to assure continued qualification of the
     Certificate as an IRA under Section 408(b) of the Code (and any successor
     provision) as in effect from time to time. The Participant has the right to
     refuse to accept any such amendment; however, we shall not be held liable
     for any tax consequences incurred by the Participant as a result of such
     refusal.

14.  The tables in the Annuity Payment Options section are deleted and replaced
     by the following:

                     VARIABLE ANNUITY PAYMENT OPTIONS TABLE

BASIS OF COMPUTATION
The actuarial basis for the Table of Annuity Rates is the 1983a Annuity
Mortality Table with projection and an effective annual Assumed Investment Rate
of 3.5%. The mortality table is projected using Projection Scale G factors,
assuming annuitization in the year 2000, and assumes an equal distribution of
males and females. The Variable Annuity Payment Options Table does not include
any applicable premium tax.

                     ANCHOR NATIONAL LIFE INSURANCE COMPANY

                    INDIVIDUAL RETIREMENT ANNUITY ENDORSEMENT

This Endorsement amends the Contract to which it is attached so that it may
qualify as an Individual Retirement Annuity (IRA) under Section 408(b) of the
Internal Revenue Code (Code) and the Regulations under that Section. The
endorsement may be amended from time to time to comply with changes in the
Internal Revenue Code. The Owner has the right to refuse to accept any such
amendment; however, we shall not be held liable for any tax consequences
incurred by the Owner as a result of such refusal. In the case of a conflict
with any provision in the Contract, the provisions of this Endorsement will
control. The effective date of this Endorsement is the Contract Date shown on
the Contract Data Page. The Contract is amended as follows:

1.   The Owner, Annuitant and Payee shall be the same individual. The Owner,
     Annuitant and Payee cannot be changed, except as otherwise permitted under
     the IRC and applicable regulations. All distributions made while the Owner
     is alive must be made to the Owner.

2.   The interest of the Owner under this Contract shall be nonforfeitable
     except as provided by law.

3.   This Contract may not be sold, assigned, discounted, pledged as collateral
     for a loan or as security for the performance of any obligation or for any
     other purpose, or otherwise transferred (other than a transfer incident to
     a divorce or separation instrument in accordance with Section 408(d)(6) of
     the Code) to any person other than to the Company.

4.   This Contract is established for the exclusive benefit of the Owner and his
     or her Beneficiary(ies).

5.   Except in the case of a rollover contribution (as permitted by Code
     Sections 402(c), 403(a)(4), 403(b)(8), or 408(d)(3)), or a contribution
     made in accordance with the terms of a Simplified Employee Pension (SEP) as
     described in Code Section 408(k), or a nontaxable transfer from an
     individual retirement account under 408(a) of the Code or another IRA under
     Section 408(b) of the Code, contributions shall not exceed $2,000 for any
     taxable year. All contributions must be in cash.

     Any refund of premiums (other than those attributable to excess
     contributions) will be applied, before the close of the calendar year
     following the year of the refund, toward the payment of future premiums or
     the purchase of additional benefits.

     No contribution will be accepted under a SIMPLE IRA plan established by any
     employer pursuant to Code section 408(p). No transfer or rollover of funds
     attributable to contributions made by a particular employer under its
     SIMPLE IRA plan will be accepted from a SIMPLE IRA, that is, an IRA used in
     conjunction with a SIMPLE IRA plan, prior



                                       1
<PAGE>   14

     to the expiration of the 2-year period beginning on the date the individual
     first participated in that employer's SIMPLE IRA plan.

6.   Unless otherwise permitted under applicable law, the Owner's entire
     interest in the Contract shall be distributed no later than the "required
     beginning date," or commence to be distributed beginning no later than the
     "required beginning date," over

     (a)  the life of the Owner, or the lives of the Owner and his or her
          designated Beneficiary (within the meaning of section 401(a) of the
          Code), or

     (b)  a period certain not extending beyond the life expectancy of the
          Owner, or the joint and last survivor expectancy of the Owner and his
          or her Beneficiary as required by law.

     As used in this Endorsement, the term "required beginning date" means April
     1 of the calendar year following the calendar year in which the Owner
     attains age 70 1/2, or such later date provided by law.

     Payments must be made in periodic payments at intervals of no longer than
     one year. In addition, 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.

     If the Owner's interest is to be distributed over a period greater than one
     year, the amount to be distributed by December 31 of each year (including
     the year in which the required beginning date occurs) will be made in
     accordance with the requirements of Code Section 401(a)(9), including the
     incidental death benefit requirements of Code Section 401(a)(9)(G), and the
     regulations thereunder, including the minimum distribution incidental
     benefit requirement of Code Section 1.401(a)(9)-2 of the Proposed Income
     Tax Regulations.

     Life expectancy is computed by use of the expected return multiples in
     Tables V and VI of Section 1.72-9 of the Income Tax Regulations. Unless
     otherwise elected by the Owner by the time distributions are required to
     begin, life expectancies shall be recalculated annually. Such election
     shall be irrevocable by the Owner and shall apply to all subsequent years.
     The life expectancy of a non-spouse designated Beneficiary may not be
     recalculated. Instead, life expectancy will be calculated using the
     attained age of such designated Beneficiary during the calendar year in
     which the Owner attains age 70 1/2, and payments for subsequent years shall
     be calculated based on such life expectancy reduced by one for each
     calendar year which has elapsed since the calendar year life expectancy was
     first calculated. Life expectancy for distributions under an Annuity
     Payment Option may not be recalculated.

7.   Unless otherwise permitted under applicable law, upon the death of the
     Owner:

     (a)  if the Owner dies on or after the required beginning date (or if
          distributions have begun before the required beginning date as
          irrevocable annuity payments or


                                       2

          income payments, whichever term is applicable), the remaining portion
          of the Owner's interest (if any) shall be distributed at least as
          rapidly as under the method of distribution in effect as of the
          Owner's death;

     (b)  if the Owner dies before the required beginning date and an
          irrevocable annuity distribution has not begun, the entire interest
          will be distributed by December 31 of the calendar year which contains
          the fifth anniversary of the Owner's death except that:

          (1)  if the interest is payable to an individual who is the Owner's
               designated Beneficiary, the designated Beneficiary may elect to
               receive the entire interest over the life of the designated
               Beneficiary or over a period not extending beyond the life
               expectancy of the designated Beneficiary, commencing on or before
               December 31 of the calendar year immediately following the
               calendar year in which the Owner died; or

          (2)  if the designated Beneficiary is the Owner's surviving spouse,
               the surviving spouse may elect to receive the entire interest
               over the life of the surviving spouse or over a period not
               extending beyond the life expectancy of the surviving spouse,
               commencing at any date on or before the later of (A) December 31
               of the calendar year immediately following the calendar year in
               which the Owner died or (B) December 31 of the calendar year in
               which the Owner would have attained age 70 1/2. If the surviving
               spouse dies before distributions begin, the limitations of this
               paragraph 7 (without regard to this paragraph (b)) will be
               applied as if the surviving spouse were the Owner.

               An irrevocable election of the method of distribution by a
               designated Beneficiary who is the surviving spouse must be made
               no later than the earlier of December 31 of the calendar year
               containing the fifth anniversary of the Owner's death or the date
               distributions are required to begin pursuant to this paragraph
               (b).

          (3)  if the designated Beneficiary is the Owner's surviving spouse,
               the spouse may irrevocably elect to treat the Contract as his or
               her own IRA. This election will be deemed to have been made if
               such surviving spouse, subject to the requirements of Section 5
               of this Endorsement, (i) makes a regular IRA contribution to the
               Contract, (ii) makes a rollover to or from the Contract, or (iii)
               fails to elect that his or her interest will be distributed in
               accordance with one of the preceding provisions of this paragraph
               (b).

               An irrevocable election of the method of distribution by a
               designated Beneficiary who is not the surviving spouse must be
               made no later than December 31 of the calendar year immediately
               following the calendar year in which the Owner died. If no such
               election is made, the entire interest



                                       3
<PAGE>   16

               will be distributed by December 31 of the calendar year
               containing the fifth anniversary of the Owner's death.

     Life expectancy is computed by use of the expected return multiples in
     Tables V and VI of Section 1.72-9 of the Income Tax Regulations. For
     purposes of distributions beginning after the Owner's death, unless
     otherwise elected by the surviving spouse by the time distributions are
     required to begin, life expectancies shall be recalculated annually. Such
     election shall be irrevocable by the surviving spouse and shall apply to
     all subsequent years. In the case of any other designated Beneficiary, life
     expectancies shall be calculated using the attained age of such designated
     Beneficiary during the calendar year in which distributions are required to
     begin pursuant to this section, and payments for any subsequent calendar
     year shall be calculated based on such life expectancy reduced by one for
     each calendar year which has elapsed since the calendar year life
     expectancy was first calculated. Life expectancy for distributions under an
     Annuity Payment Option in the Contract may not be recalculated.

     Distributions under this section are considered to have begun if
     distributions are made on account of the Owner reaching his or her required
     beginning date or if prior to the required beginning date distributions
     irrevocably commence over a period permitted and in an annuity form
     acceptable under Section 1.401(a)(9) of the Proposed Income Tax
     Regulations.

8.   The Company shall furnish annual calendar year reports concerning the
     status of the Contract.

The following provisions entitled MISSTATEMENT OF AGE, PROOF OF AGE AND SURVIVAL
and the table of Annuity Payment Options apply to Simplified Employee Pension
(SEP) contracts only:

9.   The MISSTATEMENT OF AGE OR SEX section of the Contract is deleted and
     replaced by the following section entitled MISSTATEMENT OF AGE.

     MISSTATEMENT OF AGE
     If the Age of any Annuitant has been misstated, future annuity payments
     will be adjusted using the correct Age according to Our rates in effect on
     the date that annuity payments were determined. Any overpayment from the
     Fixed Account Options, plus interest at the rate of 4% per year, will be
     deducted from the next payment(s) due. Any underpayment from the Fixed
     Account Options, plus interest at the rate of 4% per year, will be paid in
     full with the next payment due. Any overpayment from the Variable
     Portfolios ("Subaccounts") will be deducted from the next payment(s) due.
     Any underpayment from the Variable Portfolios will be paid in full with the
     next payment due.

10.  The PROOF OF AGE, SEX OR SURVIVAL section of the Contract is deleted and
     replaced by the following section entitled PROOF OF AGE AND SURVIVAL.



                                       4
<PAGE>   17

     PROOF OF AGE AND SURVIVAL. We may require satisfactory proof of correct age
     at anytime. If any payment under this Contract depends on the Annuitant
     being alive, we may require satisfactory proof of survival.

11.  Except to the extent Treasury regulations allow us to offer additional
     Annuity Payment Options that are acceptable to us, only Annuity Payment
     Options 1 and 1v, 2 and 2v, 3 and 3v, 4 and 4v, 5 and 5v shall be offered
     unless we consent to the use of an additional option. Under Annuity Payment
     Options 2 and 2v, and 3 and 3v, the designated second person must be either
     the Owner's spouse or an individual who is not more than 10 years younger
     than the Owner. Annuity Payment Options 3 and 3v are not available to an
     Owner and the designated second person where the life expectancy of the
     Owner and such person is less than 10 years. Also, Annuity Payment Options
     4 and 4v are not available to an Owner where the Owner's life expectancy is
     less than 10 years, and Annuity Payment Options 5 and 5v are not available
     to an Owner where the Owner's life expectancy is less than 5 years.

     Any additional Annuity Payment Option under the Contract must meet the
     requirements of section 408(b) of the Code and applicable regulations. The
     provisions of this Endorsement reflecting the requirements of Code Sections
     401(a)(9) and 408(b) override any additional Annuity Payment Option
     inconsistent with such requirements.

     If a guaranteed or specified period of payments is chosen under an Annuity
     Payment Option, the length of the period must not exceed the shorter of (1)
     the Owner's life expectancy, or if a designated second person is named, the
     joint and last survivor expectancy of the Owner and the designated second
     person, and (2) the applicable maximum period under Section 1.401(a)(9)-2
     of the Proposed Income Tax Regulations.

12.  If you return the Contract within 10 days after the Contract Date, the
     Company will refund the amount of your Purchase Payments, without
     adjustment for such items as sales commissions, administrative expenses,
     and fluctuation in market value for the Valuation Period in which the
     Contract is received. We reserve the right to allocate your Purchase
     Payment(s) to the Cash Management Subaccount until the end of the 10 day
     period. Thereafter, allocations will be made as shown on the Contract Data
     Page.

13.  The provisions of this Endorsement are intended to comply with the
     requirements of the Code and applicable regulations for IRAs under Section
     408(b) of the Code. The Company reserves the right to amend the Contract
     and this Endorsement from time to time, without the Owner's consent, when
     such amendment is necessary to assure continued qualification of the
     Contract as an IRA under Section 408(b) of the Code (and any successor
     provision) as in effect from time to time. The Owner has the right to
     refuse to accept any such amendment; however, we shall not be held liable
     for any tax consequences incurred by the Owner as a result of such refusal.

14.  The tables in the Annuity Payment Options section are deleted and replaced
     by the following:

                     VARIABLE ANNUITY PAYMENT OPTIONS TABLE

BASIS OF COMPUTATION
The actuarial basis for the Table of Annuity Rates is the 1983a Annuity
Mortality Table with projection and an effective annual Assumed Investment Rate
of 3.5%. The mortality table is projected using Projection Scale G factors,
assuming annuitization in the year 2000, and assumes an equal distribution of
males and females. The Variable Annuity Payment Options Table does not include
any applicable premium tax.
