Under "10. Other Information" on page P-7 of the Profile, the following is
inserted above "Free Look Period:"
OPTIONAL MINIMUM GUARANTEED ANNUITY PAYOUT RIDER: This optional rider
is available for a separate monthly charge. This rider guarantees you a
minimum amount of fixed annuity lifetime income during the annuity
payout phase, subject to certain conditions. On each contract
anniversary a minimum guaranteed annuity payout benefit base is
determined. This minimum guaranteed annuity payout benefit base is the
value that will be annuitized should you exercise the rider.
Annuitization under this rider will occur at the guaranteed annuity
purchase rates listed under the Annuity Option Tables in your Contract.
The minimum guaranteed annuity payout benefit base is equal to the
greatest of:
(a) the accumulated value increased by any positive market value
adjustment (the "accumulated value"); or
(b) accumulated value on the effective date of the rider compounded daily
at an annual rate of 5% plus gross payments made thereafter
compounded daily at an annual rate of 5%, starting on the date each
payment is applied, decreased proportionately to reflect withdrawals;
or
(c) the highest accumulated value of all contract anniversaries since the
rider effective date, as determined after the accumulated value of
each contract anniversary is increased for subsequent payments and
decreased proportionately for subsequent withdrawals.

In the Summary on page 9 of the Prospectus, the following is added to the end
of the section entitled "What Happens In the Annuity Payout Phase?":
An optional Minimum Guaranteed Annuity Payout Rider is available for a
separate monthly charge. See "M. Optional Minimum Guaranteed Annuity
Payout Rider" under "DESCRIPTION OF THE CONTRACT." If elected, the
rider guarantees the Annuitant a minimum amount of fixed annuity
lifetime income during the annuity payout phase, subject to certain
conditions. On each Contract anniversary a Minimum Guaranteed Annuity
Payout Benefit Base is determined. The Minimum Guaranteed Annuity Payout
Benefit Base is the value that will be annuitized should you exercise
the Rider. Annuitization under this Rider will occur at the guaranteed
annuity purchase rates listed under the Annuity Option Tables in your
Contract. The Minimum Guaranteed Annuity Payout Benefit Base is equal
to the greatest of:
(a) the Accumulated Value increased by any positive Market Value
Adjustment (the "Accumulated Value"); or
(b) Accumulated Value on the effective date of the Rider compounded daily
at an annual rate of 5% plus gross payments made thereafter
compounded daily at an annual rate of 5%, starting on the date each
payment is applied, decreased proportionately to reflect withdrawals;
or
(c) the highest Accumulated Value of all Contract anniversaries since the
Rider effective date, as determined after the Accumulated Value of
each Contract anniversary is increased for subsequent payments and
decreased proportionately for subsequent withdrawals.
For each withdrawal described in (b) and (c) above, the proportionate
reduction is calculated by multiplying the (b) or (c) value determined
immediately prior to the withdrawal by the following fraction:

charge is assessed by multiplying the Accumulated Value on the last day
of each month and on the date the Rider is terminated by 1/12th of the
following annual percentage rates:

lower, the Owner may choose not to exercise the Rider and instead
annuitize under current annuity factors. See "M. Optional Minimum
Guaranteed Annuity Payout Rider" below.
<PAGE>
On pages 48 and 49 of the Prospectus, "M. NORRIS Decision" is renamed "N.
NORRIS Decision," "N. Computation of Values" is renamed "O. Computation of
Values" and the following is inserted:
M. OPTIONAL MINIMUM GUARANTEED ANNUITY PAYOUT RIDER
An optional Minimum Guaranteed Annuity Payout Rider is available for a
separate monthly charge. The Minimum Guaranteed Annuity Payout Rider
guarantees a minimum amount of fixed annuity lifetime income during the
annuity payout phase, subject to the conditions described below. On
each Contract anniversary a Minimum Guaranteed Annuity Payout Benefit
Base is determined. The Minimum Guaranteed Annuity Payout Benefit Base
is the value that will be annuitized if the Rider is exercised.
Annuitization under this Rider will occur at the guaranteed annuity
purchase rates listed under the Annuity Option Tables in the Contract.
The Minimum Guaranteed Annuity Payout Benefit Base is equal to the
greatest of:
(a) the Accumulated Value increased by any positive Market Value
Adjustment (the "Accumulated Value"); or
(b) Accumulated Value on the effective date of the Rider compounded daily
at an annual rate of 5% plus gross payments made thereafter
compounded daily at an annual rate of 5%, starting on the date each
payment is applied, decreased proportionately to reflect withdrawals;
or
(c) the highest Accumulated Value of all Contract anniversaries since the
Rider effective date, as determined after the Accumulated Value of
each Contract anniversary is increased for subsequent payments and
decreased proportionately for subsequent withdrawals.
For each withdrawal described in (b) and (c) above, the proportionate
reduction is calculated by multiplying the (b) or (c) value determined
immediately prior to the withdrawal by the following fraction:
amount of the withdrawal
------------------------
the Accumulated Value determined immediately prior to the withdrawal
CONDITIONS OF ELECTION OF THE MINIMUM GUARANTEED ANNUITY PAYOUT RIDER.
-The Owner may elect the Minimum Guaranteed Annuity Payout Rider at
Contract issue or at any time thereafter, however, if the Rider is not
elected within thirty days after Contract issue or within thirty days
after a Contract anniversary date, the effective date of the Rider will
be the following Contract anniversary date.
-The Owner may not elect a Rider with a ten-year waiting period if at the
time of election the Annuitant has reached his or her 78th birthday. The
Owner may not elect a Rider with a fifteen-year waiting period if at the
time of election the Annuitant has reached his or her 73rd birthday.
CONDITIONS OF EXERCISE OF THE MINIMUM GUARANTEED ANNUITY PAYOUT RIDER.
-The Owner may only exercise the Minimum Guaranteed Annuity Payout Rider
within thirty days after any Contract anniversary following the
expiration of a ten or fifteen-year waiting period from the effective
date of the Rider.
-The Owner may only annuitize under a fixed annuity payout option
involving a life contingency as provided under "K. Description of Variable
Annuity Payout Options."
-The Owner may only annuitize at the guaranteed annuity purchase rates
listed under the Annuity Option Tables in the Contract.
TERMINATION OF THE MINIMUM GUARANTEED ANNUITY PAYOUT RIDER.
-The Owner may not terminate the Minimum Guaranteed Annuity Payout Rider
prior to the seventh Contract anniversary after the effective date of
the Rider, unless such termination occurs on or within thirty days
<PAGE>
after a Contract anniversary and in conjunction with the purchase of a
Minimum Guaranteed Annuity Payout Rider with a waiting period of equal or
greater length at its then current price, if available.
-After the seventh Contract anniversary from the effective date of the
Rider the Owner may terminate the Rider at any time.
-The Owner may repurchase a Rider with a waiting period equal to or
greater than the Rider then in force at the new Rider's then current
price, if available, however, repurchase may only occur on or within
thirty days of a Contract anniversary.
- Other than in the event of a repurchase, once terminated the Rider may
not be purchased again.
-The Rider will terminate upon surrender of the Contract or the date that
a death benefit is payable if the Contract is not continued under "H. The
Spouse of the Owner as Beneficiary" (see "DESCRIPTION OF THE CONTRACT").
From time to time the Company may illustrate minimum guaranteed income
amounts under the Minimum Guaranteed Annuity Payout Rider for
individuals based on a variety of assumptions, including varying rates
of return on the value of the Contract during the accumulation phase,
annuity payout periods, annuity payout options and Minimum Guaranteed
Annuity Payout Rider waiting periods. Any assumed rates of return are
for purposes of illustration only and are not intended as a
representation of past or future investment rates of return.
For example, the illustration below assumes an initial payment of
$100,000 for an Annuitant age 60 (at issue) and exercise of a Minimum
Guaranteed Annuity Payout Rider with a ten-year waiting period. The
illustration assumes that no subsequent payments or withdrawals are made
and that the annuity payout option is a Life Annuity With Payments
Guaranteed For 10 Years. The values below have been computed based on a
5% net rate of return and are the guaranteed minimums that would be
received under the Minimum Guaranteed Annuity Payout Rider. The
minimum guaranteed benefit base amounts are the values that will be
annuitized. Minimum guaranteed annual income values are based
on a fixed annuity payout.

(1) Other fixed annuity options involving a life contingency other than
Life Annuity With Payments Guaranteed For 10 Years are available.
See "K. Description of Variable Annuity Payout Options."
The Minimum Guaranteed Annuity Payout Rider does not create Accumulated
Value or guarantee performance of any investment option. Because this
Rider is based on conservative actuarial factors, the level of lifetime
income that it guarantees may often be less than the level that would be
provided by application of
<PAGE>
Accumulated Value at current annuity factors. Therefore, the Rider
should be regarded as a safety net. As described above, withdrawals
will reduce the Benefit Base.
Under "CHARGES AND DEDUCTIONS" on page 52 of the Prospectus, "C. Premium
Taxes" is renamed "D. Premium Taxes," "D. Contingent Deferred Sales Charge"
is renamed "E. Contingent Deferred Sales Charge" and the following is
inserted:
C. OPTIONAL MINIMUM GUARANTEED ANNUITY PAYOUT CHARGE
Subject to state availability, the Company offers an optional Minimum
Guaranteed Annuity Payout Rider that may be elected by the Owner. A
separate monthly charge is made for the Rider. On the last day of each
month and on the date the Rider is terminated, a charge equal to 1/12th
of an annual rate (see table below) is made against the Accumulated
Value of the Contract at that time. The charge is made through a
pro-rata reduction of the Accumulated Value of the Sub-Accounts, the
Fixed Account and the Guarantee Period Accounts (based on the relative
value that the Accumulation Units of the Sub-Accounts, the dollar
amounts in the Fixed Account and the dollar amounts in the Guarantee
Period Accounts bear to the total Accumulated Value).
The applicable charge is assessed on the Accumulated Value on the last day
of each month and on the date the Rider is terminated, multiplied by
1/12th of the following annual percentage rates:
<TABLE>
<S> <C>
Minimum Guaranteed Annuity Payout Rider with ten-year waiting period.........0.25%
Minimum Guaranteed Annuity Payout Rider with fifteen-year waiting period.....0.15%

For a description of the Rider, see "M. Optional Minimum Guaranteed
Annuity Payout Rider" under "DESCRIPTION OF THE CONTRACT," above.
After the section entitled "LEGAL MATTERS" on page 70 of the Prospectus, the
following is inserted:
YEAR 2000 COMPLIANCE
The Year 2000 issue is the result of computer programs being written
using two digits rather than four to define the applicable year. Any of
the Company's computer programs that have date-sensitive software may
recognize a date using "00" as the year 1900 rather than the year 2000.
This could result in a system failure or miscalculations causing
disruptions of operations, including, among other things, a temporary
inability to process transactions, send invoices or engage in similar
normal business activities.
Based on a third party assessment, the Company determined that
significant portions of its software required modification or
replacement to enable its computer systems to properly process dates
beyond December 31, 1999. The Company is presently completing the
process of modifying or replacing existing software and believes that
this action will resolve the Year 2000 issue. However, if such
modifications and conversions are not made, or are not completed timely,
or should there be serious unanticipated interruptions from unknown
sources, the Year 2000 issue could have a material adverse impact on the
operations of the Company. Specifically, the Company could experience,
among other things, an interruption in its ability to collect and
process premiums, process claim payments, safeguard and manage its
invested assets, accurately maintain policyholder information,
accurately maintain accounting records, and perform customer service.
Any of these specific events, depending on duration, could have a
material adverse impact on the results of operations and the financial
position of the Company.
The Company has initiated formal communications with all of its
significant suppliers and large customers to determine the extent to
which the Company is vulnerable to those third parties' failure to
remediate their own Year 2000 issue. The Company's total Year 2000
project cost and estimates to complete the project include the estimated
costs and time associated with the impact of a third party's Year 2000
issue, and are based on presently available information. However, there
can be no guarantee that the systems of other companies on which the
Company's systems rely will be timely converted, or that a failure to
convert by another company, or a conversion that is incompatible with
the Company's systems, would not have
<PAGE>
material adverse effect on the Company. The Company does not believe
that it has material exposure to contingencies related to the Year 2000
Issue for the products it has sold. Although the Company does not
believe that there is a material contingency associated with the Year
2000 project, there can be no assurance that exposure for material
contingencies will not arise.
The Company will utilize both internal and external resources to
reprogram or replace, and test both information technology and embedded
technology systems for Year 2000 modifications. The Company plans to
complete the mission critical elements of the Year 2000 by December 31,
1998. The cost of the Year 2000 project will be expensed as incurred
over the next two years and is being funded primarily through a
reallocation of resources from discretionary projects. Therefore, the
Year 2000 project is not expected to result in any significant
incremental technology cost and is not expected to have a material
effect on the results of operations. Through September 30, 1998, the
Company and its subsidiaries and affiliates have incurred and expensed
approximately $47 million related to the assessment of, and preliminary
efforts in connection with, the project and the development of a
remediation plan. The total remaining cost of the project is estimated
at between $30-40 million.
The costs of the project and the date on which the Company plans to
complete the Year 2000 modifications are based on management's best
estimates, which were derived utilizing numerous assumptions of future
events including the continued availability of certain resources, third
party modification plans and other factors. However, there can be no
guarantee that these estimates will be achieved and actual results could
differ materially from those plans. Specific factors that might cause
such material differences include, but are not limited to, the
availability and cost of personnel trained in this area, the ability to
locate and correct all relevant computer codes, and similar
uncertainties.
