                    GUARANTEED MINIMUM ACCOUNT VALUE ("GMAV")
                                   ENDORSEMENT

Notwithstanding any provision in the Contract or Certificate ("Contract") to the
contrary, this Endorsement becomes a part of the Contract to which it is
attached. Should any provision in this Endorsement conflict with the Contract,
the provisions of this Endorsement will prevail.

EFFECTIVE DATE:  [DATE]

GMAV DATE:         [DATE]

                                   DEFINITIONS

EFFECTIVE DATE

The date shown above when this Endorsement becomes effective. If this
Endorsement is elected at or prior to Contract issue, the Effective Date is the
date Your Contract is issued and effective.

GMAV BASE

The basis that is used to determine the GMAV Benefit (as described below). The
GMAV Base is calculated from the Effective Date of this Endorsement to the GMAV
Date. After the GMAV Date there is no GMAV Base as described in this
Endorsement.

THE GMAV BASE IS USED SOLELY FOR THE PURPOSE OF CALCULATING THE GMAV BENEFIT AND
DOES NOT PROVIDE A CONTRACT VALUE OR GUARANTEE PERFORMANCE OF ANY INVESTMENT
OPTION.

GMAV BENEFIT

The benefit provided by this Endorsement as the amount added to the Contract
Value on the GMAV Date. This amount, if any, will be allocated to the [[Cash
Management] or [Money Market]] Portfolio or equivalent Portfolio on the GMAV
Date. The GMAV Benefit is not considered a Premium or Purchase Payment
("Purchase Payment"). The GMAV Benefit has no value on any date other than on
the GMAV Date.

GMAV DATE

The date, shown above, on which the GMAV Benefit is calculated and added to Your
Contract Value.

SPOUSAL BENEFICIARY

Your spouse, if designated as Your primary Beneficiary on the date of Your
death, who elects to continue the Contract as the new Owner or Participant
("Owner") upon Your death.

                                 GMAV PROVISIONS

This Endorsement provides a GMAV Benefit subject to the terms and conditions
described herein. On the GMAV Date, if the GMAV Base is greater than the
Contract Value, We will add the GMAV Benefit to Your Contract Value.

GMAV CHARGE

The charge deducted from Your Contract Value on a quarterly basis beginning one
quarter following the Effective Date of this Endorsement. A full quarterly
charge will also be deducted on the GMAV Date or upon full surrender or
annuitization of Your Contract prior to the GMAV Date. The GMAV Charge will not
be deducted after the GMAV Date.

</TABLE>

The GMAV Charge deducted on a quarterly basis is calculated as one-fourth of the
Annualized GMAV Charge Percentage applied to any positive difference between the
Contract Value and any [Gross] Purchase Payments made [more than 1 year(s)]
since the Effective Date.

                                       1

CALCULATION OF THE GMAV BASE AND GMAV BENEFIT

The GMAV Base on any date following the Effective Date, up to and including the
GMAV Date, is equal to (a) plus (b) minus (c) where:

(a)   is/are the [Gross] Purchase Payment(s) received on or after the Effective
      Date multiplied by the percentage as specified in the table below;

(b)   is, if this Endorsement is elected after Contract issue, the Contract
      Value on the Effective Date multiplied by the percentage for the Effective
      Date as specified in the table below;

(c)   is a proportional adjustment for each partial withdrawal (including any
      charges on each such withdrawal) taken subsequent to the Effective Date. A
      proportional adjustment is the GMAV Base immediately prior to a withdrawal
      multiplied by the percentage by which the Contract Value is reduced at the
      time of that withdrawal.

If the GMAV Base is greater than the Contract Value on the GMAV Date, the GMAV
Benefit is calculated as the difference between the GMAV Base and the Contract
Value on the GMAV Date.

The table below is used for purposes of calculating the GMAV Base as determined
by the time elapsed since the Effective Date of this Endorsement and the day on
which [Gross] Purchase Payments are received by Us and deposited into Your
Contract.

SPOUSAL CONTINUATION

If Your Spousal Beneficiary elects to continue the Contract prior to the GMAV
Date, the Spousal Beneficiary must continue this Endorsement subject to the
terms and conditions described herein. The Effective Date and the GMAV Date, as
shown on page one of this Endorsement, will not change as a result of Spousal
Continuation.

TERMINATION

Once elected and prior to the GMAV Date, this Endorsement and its corresponding
charge cannot be terminated unless the Contract terminates as a result of any
one of the following occurrences:

      (a)   A Death Benefit is paid (as described under the [Death Provisions or
            Death Benefit] section of Your Contract) unless Spousal Continuation
            is elected; or

      (b)   The Contract is fully withdrawn or surrendered; or

      (c)   The Contract is annuitized.

This Endorsement terminates on the GMAV Date.

October 1 of each year and on the Maturity Date, commencing on the first such
Interest Payment Date next succeeding the Original Issue Date, provided that if
the Original Issue Date is after a Regular Record Date and before the Interest

Predecessor Notes) is registered at the close of business on the Regular Record

notice, the Depositary will notify the Trustee of the portion of the payment to
be made by the Trustee which is to be made in the Specified Currency and the
applicable wire transfer instructions. In such event, the Trustee will pay the
beneficial holder directly.] [insert if the Security is to be a Certificated

and interest payments and need not file a separate election for each payment.
Such election will remain in effect until revoked by written notice to the
Trustee, but written notice of such revocation must be received by the Trustee
on or prior to the applicable Regular Record Date or at least 15 days prior to
Maturity, as the case may be.]

designated by such person, but only if appropriate payment instructions have
been received in writing by the Trustee on or prior to the Regular Record Date.]

                                  (Fixed Rate)

      This Note is one of a duly authorized issue of securities of the Company
(herein called the "Notes"), issued and to be issued in one or more series under
an Indenture dated as of April 15, 1985, as supplemented from time to time
(herein called the "Indenture"), between the Company and U.S. Bank Trust
National Association, as successor Trustee (herein called the "Trustee", which
term includes any successor trustee under the Indenture), to which Indenture and
all indentures supplemental thereto reference is hereby made for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee and the Holders of the Notes and of the terms upon
which the Notes are, and are to be, authenticated and delivered. This Note is
one of the series designated on the face hereof. The Notes of this series may be
denominated in different currencies, bear different dates, mature at different
times and bear interest at different rates. The Notes of this series may be
issued from time to time in an aggregate principal amount of up to
$[___________] (including in such amount the offering price of any such Notes
sold at a discount), which amount may be increased if duly authorized by the
Company.

      The United States dollar equivalent of Notes denominated in currencies
other than United States dollars will be determined by the Exchange Rate Agent
on the basis of the noon buying rate for cable transfers in the City of New York
as determined by the Federal Reserve Bank of New York (the "Market Exchange
Rate") for such currencies on the Business Day (as defined below) immediately
preceding the applicable issue dates.

      Interest payments for this Note will include interest accrued from and
including the last date in respect of which interest has been paid or duly
provided for (or from and including the Original Issue Date if no interest has
been paid or provided for) to but excluding the Interest Payment Dates. Interest
payments for this Note shall be computed and paid on the basis of a 360-day year
of twelve 30-day months.

      If the Company has the option with respect to this Note to reset the
interest rate, such option will be indicated on the face hereof, together with
(i) the date or dates on which such interest rate may be reset (each an
"Optional Reset Date") and (ii) the basis or formula, if any, for such
resetting. The Company may exercise such option by notifying the Trustee of such
exercise at least 45 but not more than 60 days prior to an Optional Reset Date.
Not later than 40 days prior to such Optional Reset Date, the Trustee will mail
to the Holder hereof a notice (the "Reset Notice"), first class, postage
prepaid, setting forth (i) the election of the Company to reset the interest
rate, (ii) such new interest rate, and (iii) the provisions, if any, for
redemption during the period from such Optional Reset Date to the next Optional
Reset Date or, if there is no such next Optional Reset Date, to the Stated
Maturity of this Note (each such period a "Subsequent

                                       6
<PAGE>
Interest Period"), including the date or dates on which or the period or periods
during which and the price or prices at which such redemption may occur during
such Subsequent Interest Period.

      Notwithstanding the foregoing, not later than 20 days prior to an Optional
Reset Date, the Company may, at its option, revoke the interest rate provided
for in the Reset Notice and establish a higher interest rate for the Subsequent
Interest Period commencing on such Optional Reset Date by mailing or causing the
Trustee to mail notice of such higher interest rate first class, postage
prepaid, to the Holder hereof. Such notice shall be irrevocable. If the interest
rate is reset on an Optional Reset Date this Note will bear such higher interest
rate.

      If the Company elects to reset the interest rate of this Note, the Holder
hereof will have the option to elect repayment of this Note by the Company on
any Optional Reset Date at a price equal to the principal amount hereof plus any
accrued interest to such Optional Reset Date. In order for this Note to be so
repaid on an Optional Reset Date, the Holder hereof must follow the procedures
set forth below for optional repayment, except that the period for delivery of
this Note or notification to the Trustee shall be at least 25 but not more than
35 days prior to such Optional Reset Date and except that a Holder who has
tendered this Note for repayment pursuant to a Reset Notice may, by written
notice to the Trustee, revoke any such tender for repayment until the close of
business on the tenth day prior to such Optional Reset Date.

      If the Company has the option to extend the Stated Maturity of this Note
for one or more periods (each an "Extension Period") up to but not beyond a date
(the "Final Maturity Date") set forth on the face hereof, such option will be
indicated on the face hereof together with the basis or formula, if any, for
setting the interest rate applicable to any such Extension Period. The Company
may exercise such option with respect to this Note by notifying the Trustee of
such exercise at least 45 but not more than 60 days prior to the Stated Maturity
of this Note in effect prior to the exercise of such option (the "Original
Stated Maturity"). No later than 40 days prior to the Original Stated Maturity,
the Trustee will mail to the Holder hereof a notice (the "Extension Notice")
relating to such Extension Period, first class, postage prepaid, setting forth
(i) the election of the Company to extend the Stated Maturity of this Note, (ii)
the new Stated Maturity, (iii) the interest rate applicable to the Extension
Period, and (iv) the provisions, if any, for redemption during the Extension
Period, including the date or dates on which or the period or periods during
which and the price or prices at which such redemption may occur during the
Extension Period. Upon the mailing by the Trustee of an Extension Notice to the
Holder hereof, the Stated Maturity of this Note shall be extended automatically
as set forth in the Extension Notice, and, except as modified by the Extension
Notice and as described in the next paragraph, this Note will have the same
terms as prior to the mailing of such Extension Notice.

      Notwithstanding the foregoing, not later than 20 days prior to the
Original Stated Maturity for this Note, the Company may, at its option, revoke
the interest rate provided for in the Extension Notice and establish a higher
interest rate for the Extension Period by mailing or causing the Trustee to mail
notice of such higher interest rate first class, postage prepaid, to the Holder
hereof. Such notice shall be irrevocable. All Notes with respect to which the
Stated Maturity is extended will bear such higher interest rate for the
Extension Period.

      If the Company elects to extend the Stated Maturity of this Note, the
Holder hereof will have the option to elect repayment of this Note by the
Company at the Original Stated Maturity at a price equal to the principal amount
hereof plus any accrued interest to such date. In order for this Note to be so
repaid on the Original Stated Maturity, the Holder hereof must follow the
procedures set forth below for optional repayment, except that the period for
delivery of this Note or notification to the Trustee shall be at least 25 but
not more than 35 days prior to the Original Stated Maturity and except that a
Holder who has tendered this Note for repayment pursuant to an Extension Notice
may, by written notice to the Trustee, revoke any such tender for repayment
until the close of business on the tenth day prior to the Original Stated
Maturity.

      Unless one or more Redemption Dates is specified on the face hereof, this
Note shall not be redeemable at the option of the Company before the Maturity
Date specified on the face hereof. If one or more Redemption Dates (or ranges of
Redemption Dates) is so specified, this Note is subject to redemption on any
such date (or during any such range) at the option of the Company, upon notice
by first-class mail, mailed not less than 30 days nor more than 60 days prior to
the Redemption Date specified in such notice, at the applicable Redemption Price
specified on the face hereof (expressed as a percentage of the principal amount
of this Note), together in the case of any such redemption with accrued interest
to the Redemption Date, but interest installments whose Stated Maturity is prior
to the Redemption Date will be payable to the Holder of this Note, or one or
more predecessor Notes, of record at the close of business on the relevant
Regular or Special Record Dates referred to on the face hereof, all as provided
in the Indenture. The Company may elect to redeem less than the entire principal
amount hereof, provided that the principal amount, if any, of this Note that
remains outstanding after such redemption is an Authorized Denomination as
defined herein.

      Unless one or more Repayment Dates is specified on the face hereof, this
Note shall not be repayable at the option of the Holder on any date prior to the
Maturity Date specified on the face hereof. If one or more Repayment Dates (or
ranges of Repayment Dates) is so specified, this Note is subject to repayment on
any such date (or during any such range) at the option of the Holder at the
applicable Repayment Price specified on the face hereof (expressed as a
percentage of the principal amount of this Note), together in the case of any
such repayment with accrued interest to the Repayment Date, but interest
installments whose Stated Maturity is prior to the Repayment Date will be
payable to the Holder of this Note, or one or more predecessor Notes, of record
at the close of business on the relevant Regular or Special Record Dates
referred to on the face hereof, all as provided in the Indenture. For this Note
to be repaid at the option of the Holder, the Trustee must receive at the
principal office of its Corporate Trust Department in the City of New York, at
least 30 days but not more than 45 days prior to the Repayment Date on which
this Note is to be repaid, this Note and a statement that the option to elect
repayment is being exercised thereby. Exercise of the repayment option by the
Holder shall be irrevocable except to the extent permitted in connection with an
interest rate reset or an extension of maturity, each as described above. The
repayment option with respect to this Note may be exercised by the Holder for
less than the entire principal amount hereof, provided that the principal
amount, if any, of this Note that remains outstanding after such repayment is an
Authorized Denomination as defined herein.

      [Insert if the Security is to be a Certificated Security - In the event of
redemption or repayment of this Note in part only, a new Note or Notes of this
series and of like tenor and for a principal amount equal to the unredeemed or
unrepaid portion will be delivered to the registered Holder upon the
cancellation hereof.]

      [Insert if the Security is to be a Global Security - In the event of
redemption or repayment of this Note in part only, the principal amount shall be

      If this is a Foreign Currency Note to be paid in United States dollars,
the United States dollar amount to be received in respect hereof will be based
upon the exchange rate as determined by the Exchange Rate Agent based on the
highest firm bid quotation for United States dollars received by such Exchange
Rate Agent at approximately 11:00 a.m., New York City time, on the second
Business Day preceding the applicable payment date from three recognized foreign
exchange dealers in the City of New York selected by the Exchange Rate Agent and
approved by the Company (one of which may be the Exchange Rate Agent) for the
purchase by the quoting dealer, for settlement on such payment date, of the
aggregate amount of the Specified Currency payable on such payment date in
respect of this Note. If no such bid quotations are available, payments will be
made in the Specified Currency, unless such Specified Currency is unavailable
due to the imposition of exchange controls or to other circumstances beyond the
Company's control, in which case the Company will be entitled to make payments
in respect hereof in United States dollars as provided below. All currency
exchange costs will be borne by the Holder hereof by deductions from such
payments.

      If a Holder is to receive payments in a Specified Currency other than
United States dollars as described on the face hereof, payments of principal of
(and premium, if any) and interest will be paid in immediately available funds
by wire transfer to an account maintained by the Holder with a bank designated
by the Holder (which in the case of Global Securities will be the Depositary or
its nominee) on or prior to the Regular Record Date or at least 15 days prior to
Maturity, as the case may be, provided that such bank has the appropriate
facilities for such a payment in the Specified Currency, provided, however, that
with respect to payments of principal and premium, if any, and interest at
Maturity this Note is presented to the Trustee in time for the Trustee to make
such payment in accordance with its normal procedures, which shall require
presentation no later than two Business Days prior to Maturity in order to
ensure the availability of immediately available funds in the Specified Currency
at Maturity.

      If payment on this Note is required to be made in a Specified Currency
other than United States dollars and such currency is unavailable in the good
faith judgment of the Company due to the imposition of exchange controls or to
other circumstances beyond the Company's control, or is no longer used by the
government of the country issuing such currency or for the settlement of
transactions by public institutions of or within the international banking
community, then all payments with respect to this Note shall be made in United
States dollars until such currency is again available or so used. The amount so
payable on any date in such Specified Currency shall be converted into United
States dollars at a rate determined by the Exchange Rate Agent on the basis of
the Market Exchange Rate on the second Business Day prior to such payment, or,
if the Market Exchange Rate is not then available, the most recently available
Market Exchange Rate or as otherwise determined in good faith by the Company if
the foregoing is impracticable.

      If this is a Foreign Currency Note, in the event of an official
redenomination of such foreign currency (including, without limitation, an
official redenomination of a foreign currency that is a composite currency) the
obligations of the Company with respect to payments on this Note denominated in
such currency shall, in all cases, be deemed immediately following such
redenomination to provide for the payment of that amount of redenominated
currency representing the amount of such obligations immediately before such
redenomination. No adjustment will be made to any amount payable under this Note
as a result of (a) any change in the value of a foreign currency relative to any
other currency due solely to fluctuations in exchange rates or (b) any
redenomination of any component currency of any composite currency (unless such
composite currency is itself officially redenominated.

      If an Event of Default with respect to Notes of this series shall occur
and be continuing, the principal of the Notes of this series may be declared due
and payable in the manner and with the effect provided in the Indenture. Unless
otherwise specified on the face hereof, if any Original Issue Discount Note (as
defined below) is redeemed by the Company or repaid at the option of the Holder,
each as described above, or if the principal of any Original Issue Discount Note
is declared to be due and payable immediately pursuant to this paragraph, the
amount of principal due and payable with respect to this Note shall be limited
to the sum of the aggregate principal amount of this Note multiplied by the
Issue Price (expressed as a percentage of the aggregate principal amount) plus
the original issue discount accrued from the date of issue to the date of
redemption, repayment or declaration, as applicable, which accrual shall be
calculated using the "interest method" (computed in accordance with generally
accepted accounting principles) in effect on the date of redemption, repayment
or declaration. Unless otherwise specified on the face hereof, an Original Issue
Discount Note is a Note which has a stated redemption price at maturity that
exceeds its Issue Price by at least 0.25% of its stated redemption price at
maturity, multiplied by the number of complete years from the Original Issue
Date to the Maturity Date for this Note.

      The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Notes of each series to be affected
under the Indenture at any time by the Company and the Trustee with the consent
of the Holders of not less than 66 2/3% in principal amount of the Notes at the
time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Notes of each series at the time Outstanding on behalf of the Holders of
all Notes of such series, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Note shall
be conclusive and binding upon such Holder and upon all future Holders of this
Note and of any Note issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Note.

      No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Note at the times, places and rate, and

                                       10

in the coin or currency, herein prescribed. However, the Indenture limits the
Holder's right to enforce the Indenture and this Note.

      As provided in the Indenture and subject to certain limitations set forth
therein and as may be set forth on the face hereof, the transfer of this Note is
registrable in the Security Register, upon surrender of this Note for
registration of transfer at the office or agency of the Company in any place
where the principal of (and premium, if any) and interest on this Note are
payable, duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Security Registrar duly executed by,
the Holder hereof or his attorney duly authorized in writing, and thereupon one
or more new Notes of this series of like tenor, of Authorized Denominations and
for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

      [Insert if the Security is a Global Security - This Note is a Global Note
and shall be exchangeable for Notes registered in the names of Persons other
than the Depositary with respect to this Global Note or its nominee only if (A)
such Depositary notifies the Company that it is unwilling or unable to continue
as Depositary for this Global Note or at any time ceases to be a clearing agency
registered as such under the Securities Exchange Act of 1934, as amended, (B)
the Company in its discretion executes and delivers to the Trustee a Company
Order that this Global Note shall be exchangeable or (C) there shall have
occurred and be continuing an Event of Default with respect to the Notes. If
this Global Note is exchangeable pursuant to the preceding sentence, it shall be
exchangeable for Notes issuable in denominations of $1,000 and any integral
multiple of $1,000 in excess thereof, registered in such names as such
Depositary shall direct.]

      The Notes of this series are issuable, in the case of Notes denominated in
United States dollars, in denominations of U.S. $1,000 and any integral multiple
of U.S. $1,000 in excess thereof and, in the case of Notes denominated in a
Specified Currency other than United States dollars, in the authorized
denominations set forth on the face hereof (in each case, an "Authorized
Denomination"). As provided in the Indenture and subject to certain limitations
set forth therein and as may be set forth on the face hereof, Notes of this
series are exchangeable for a like aggregate principal amount of Notes of this
series of like tenor of a different Authorized Denomination, as requested by the
Holder surrendering the same.

      "Business Day" means (a) with respect to any Note, any day that is not a
Saturday or Sunday and that, in the City of New York, is not a day on which
banking institutions generally are authorized or required by law, regulation or
executive order to close and (b) if the Note is denominated in a Specified
Currency other than United States dollars, not a day on which banking
institutions are authorized or required by law, regulation or executive order to
close in the principal financial center of the country issuing the Specified
Currency (but if the Specified Currency is the Euro, the day must also be a day
on which the Trans-European Automated Real-Time Gross Settlement Express
Transfer (TARGET) System is open). As used in the preceding sentence, "principal
financial center" means the capital city of the country issuing the Specified
Currency, except that with respect to United States dollars, Australian dollars,
Canadian dollars, Swiss francs and South African rand, the "principal financial
center" shall be the City of New York, Sydney, Toronto, Zurich and Johannesburg,
respectively.

      No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

Securities to The Depository Trust Company as depositary for the Global
Securities of this series (the "Depositary") or its nominee and registered in

      Prior to due presentment of this Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
