                           -        Contact your regional representative
                           -        Contact your pension service associate

                           -----------------------------------------------------
SERVICE PARTNERSHIP        The success of your plan relies on a working
                           partnership between you and The Principal. The terms
                           of the partnership are determined by the services you
                           select. A steady flow of communication between us
                           increases its quality. The services you select fall
                           into three general categories:

                           -        Base services
                           -        Unanticipated events
                           -        Member services

                           -----------------------------------------------------
BASE SERVICES              These services are needed for the daily operation of
                           your plan. The fee for these services is called the
                           Base Fee. We determine the Base Fee each year
                           depending on the services we expect to provide you at
                           the time the annual calculation is performed. You
                           will receive advance notice of your annual Base Fee
                           for each upcoming deposit year. We guarantee the Base
                           Fee for each deposit year. It can only be modified in
                           the event of a Major Business Change.

BASE SERVICES              Major Business Changes are events that have a
 (CONTINUED)               significant impact on your services. They change the
                           basic contractual agreement between us.

                           Major business changes include:

                           -        Change of plan type
                           -        Plan or contract termination
                           -        Spin-offs or mergers
                           -        A greater than 50% change in the value of
                                    the funds or number of members
                           -        Adding or removing non-proprietary funds

                           If you have a Major Business Change, other than a
                           full contract termination, we'll recalculate your
                           Base Fee for the remainder of the current deposit
                           year.

                           If you choose to terminate your contract, we'll:

                           -        Keep the same basis point for any netted
                                    fees
                           -        Prorate any billed fees based on any plan
                                    funds remaining with us until maturity

                           -----------------------------------------------------
UNANTICIPATED EVENTS       These are situations where you request us to perform
                           additional services unknown at the time of our Base
                           Fee calculation. Fees for Unanticipated Events will
                           be charged at the time they occur. Unanticipated
                           Events may include:

                           -    Supplemental services   -    Compliance services
                           -    Document changes        -    Outside our company
                                                             charges

                           not included in the Base Fee and are typically
                           deducted (if applicable) from affected member
                           accounts.

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

                           for all customers in your classification. A copy can

The Base Fee for this fund and expense projection calculation is based on the
assumptions listed above, current expense scales and standard contract
implementation procedures. The Base Fee can only be modified in the event of a
Major Business Change. Major Business Changes are events that have a significant
impact on your services. They change the basic contractual agreement between us.
In the event of a Major Business Change, the Base Fee is recalculated for the
remainder of the deposit year. Major Business Changes include:

                  -        Change of plan type
                  -        Partial plan/contract termination
                  -        Spin-offs/mergers
                  -        Greater than 50% changes in assets or number of
                           members
                  -        Adding or removing non-proprietary funds

Unanticipated Events are situations where you request us to perform additional
services unknown at the time of our Base Fee calculation. Fees for Unanticipated
Events will be charged at the time they occur. Unanticipated Events may include:

                  -        Supplemental services
                  -        Compliance services

TRANSFER RIDER

This rider IS made part of the group annuity contract to which it is attached.
Such group annuity contract is issued by us to you. All terms defined in the
contract have the same meaning where used in this rider.

The purpose of this rider is (i) to allow for the transfer to this contract of
certain Member account values from another group annuity contract issued by us,

transfers from certain types of contracts, to transfer the withdrawal charge to
which the accounts were subject under the prior contract.

The effective date of this rider is the latest of (i) the Contract Date, (ii)
the date the rider was approved for use in the state of issue of this contract
or (iii) as stated in the amendment adding it to the contract.

This rider modifies the contract as follows:

A.       By adding the following sentence to the end of the definition of
         Composite Guaranteed Rate in Article I, Section 2:

         The Composite Guaranteed Rate in effect for such Guaranteed Interest
         Investments from the date received under this contract until the last
         day of the Guarantee Period (date of payment or application, if
         earlier) will be the rate of interest such accounts would have received
         under the prior contract if the transfer to this contract had not
         occurred.

B.       By adding the following to the end of the definition of Guaranteed
         Interest Investment in Article I, Section 2:

         Transfer Contributions which consist of general account investments
         under the Prior Contract will be held in Guaranteed Interest
         Investments established under this contract for such transfer amounts.

         If the Prior Contract had a benefit floor and we agree to transfer the
         greater of (i) the value of the Member's total account under the Prior
         Contract or (ii) the benefit floor, the amount establishing the
         Guaranteed Interest Investment will be such greater amount.

C.       By adding the following to the definition of Guarantee Period in
         Article I, Section 2:

         The initial Guarantee Period for a Guaranteed Interest Investment
         established by a Transfer Contribution will end on the last day of the
         Deposit Year under this contract closest to the date the guarantee
         period would have ended under the Prior Contract had the transfer to
         this contract not occurred. In the event there is a difference of
         exactly six months between the last day of the Deposit Year under this
         contract and the last day of the deposit year under the Prior Contract,
         the initial Guarantee Period will end on the last day of the Deposit
         Year under this contract which ends just before the date the guarantee
         period would have ended under the Prior Contract.

FLEXIBLE INVESTMENT ANNUITY ENDORSEMENT RIDER

This rider is made a part of the Group Annuity Contract to which it is
attached. This contract is issued to you, the Contractholder, by us. All
terms defined in the contract have the same meaning where used in this rider.

The purpose of this rider is to clarify certain terms and language in this
contract.

The effective date of this rider will be the latest of the Contract Date, the
date of the amendment adding this rider to the contract, or the date this
rider is approved for use by the state of issue.

1.       This rider adds the following definition in ARTICLE I, SECTION 2--OTHER
         DEFINED TERMS:

         APPLICABLE U.S. TREASURY RATE means the yield associated with the
         average of accepted bids for the U.S. bonds, notes, or bills which will
         mature on the date the Guaranteed Interest Investment would have
         matured. This yield will be those provided by the WALL STREET JOURNAL,
         or a similar publication, or by an agency that provides similar
         information.

         Rates for terms of less than twelve months will not be used. The twelve
         month Treasury rate will be used for any such transaction.

         If the publication or agency does not provide a rate for the date of
         payment or application, this rate will be determined using linear
         interpolation between the rates for the maturities closest to the date
         the Investment would have matured.

2.       This rider deletes the definitions of Guaranteed Interest Rate and
         Guarantee Period found in ARTICLE I, SECTION 2--OTHER DEFINED TERMS,
         and replaces them with the following:

         GUARANTEED INTEREST RATE means the annual rates of interest determined
         and made available by us in advance for Guaranteed Interest Investments
         under contracts of this class from time to time, which, when credited
         and compounded daily, produce the effective annual interest rates. Each
         Guaranteed Interest Investment will be credited with the effective
         annual Guaranteed Interest Rate in effect for it.

         GUARANTEE PERIOD means, for each Guaranteed Interest Investment, the
         period or periods which we make available under contracts of this class
         issued under the same or similar circumstances. We reserve the right,
         in our sole discretion, to change at any time the Guarantee Periods
         available for new Guaranteed Interest Investments; provided, however,
         we will always offer at least one Guarantee Period of at least two
         years. You must provide us with Notification selecting the Guarantee
         Period for each Guaranteed Interest Investment established under this
         contract.

         Once established, the Guarantee Period for a Guaranteed Interest
         Investment will not be changed by us. If a certain Guarantee Period
         will become unavailable for future Contributions, we will notify you at
         least 60 days before the date the use of such Guarantee Period will no
         longer be available.


                                       1

3.       This rider deletes the first paragraph of ARTICLE II, SECTION
         1--CONTRIBUTIONS, and replaces it with the following:

         Contributions may be accepted under this contract on any Business Day
         on or after the Contract Date, subject to the limitations of the last
         paragraph of this Section and Article VII, Section 13. Contributions
         may be any amount determined or allowed by the Plan and accepted on
         behalf of a Member. Contributions in excess of those determined or
         allowed by the Plan for the current Plan year may be paid to us only
         with our consent We will maintain separate accounting records for each
         type of Contribution, to the extent possible under our procedures.

4.       This rider deletes ARTICLE II, SECTION 6--TRANSFERS BETWEEN
         INVESTMENTS, and replaces it with the following:

         In general, all or a portion of a Member's Investments may be
         transferred to another Investment as of any date requested subject to
         the following:

         a)   All  requests  to transfer  must be received by us at least
              7 Business  Days before the date such transfer is to occur.

              We must receive Notification to transfer from you or the
              Member, as permitted by the Plan. The Notification must specify
              the amount or percentage to be transferred and may specify the
              Investments involved. If a requested transfer from a Member's
              Investments does not specify the Investments to be transferred,
              the Order of Application will determine the Investments to be
              transferred.

         b)   A transfer from a Member's Guaranteed Interest Investment to a
              Separate Account Investment may occur only on a Valuation Date
              of such Separate Account Investment.

         c)   Except as provided in Section 7 of this Article, all transfers
              from a Guaranteed Interest Investment are subject to the charge
              contained in Article VI, Section 3. All transfers are subject
              to the limitations contained in Article VI, Section 4 and the
              Separate Account Investment Rider.

         d)   All Separate Account Investment transfers are subject to the
              provisions of the Separate Account Investment Rider.

         Any transfer under this Section will be an application from the
         Investment as of the date of transfer.

5.       This rider deletes ARTICLE II, SECTION 8--INVESTMENT MANAGER, and
         replaces it with the following:

         As set out in Sections 2 and 6 of this Article, the right to direct the
         split of Contributions between Guaranteed Interest Investments and
         Separate Account Investments and to direct any transfer between these
         Investments is reserved to you and/or the Member, all in accordance
         with provisions of the Plan.


                                       2
<PAGE>
         Application for and issuance of this contract constitutes appointment
         of and acceptance and affirmation by us that (i) we are an "investment
         manager" as described under the Employee Retirement Income Security Act
         of 1974 (ERISA) solely with respect to Plan assets held in Separate
         Accounts under this contract, except for the right reserved in the
         preceding paragraph and (ii) we are qualified to accept such
         appointment and acknowledge that by virtue of such appointment we are a
         fiduciary of the plan for this purpose, within the meaning of ERISA
         with respect to our responsibilities as investment manager.

         The Guaranteed Interest Investments are guaranteed benefit policies, as
         defined in ERISA. We are not an investment manager nor are we any kind
         of ERISA fiduciary with regard to any amounts held under the Guaranteed
         Interest Investments.

6.       This rider deletes ARTICLE V. SECTION 1--WITHDRAWAL BENEFITS,
         Subsection (d), and the first sentence of the next paragraph
         thereafter, and replaces them with the following:

         d)   We reserve the right to limit the number of withdrawals and the
              right to charge for processing such withdrawals; provided,
              however, that two (2) withdrawals will always be available each
              Deposit Year and provided further that any increase in such
              processing charge will not apply to total withdrawals made
              during or at the end of the Guarantee Periods for the
              applicable Guaranteed Interest Investments.

         The amount available will be determined as of the date we receive the
         Notification at our Corporate Center, or at some later date specified
         in the Notification.

7.       This rider deletes the portion of ARTICLE VI, SECTION 3--CHARGES FOR
         EARLY SURRENDER OF A GUARANTEED INTEREST INVESTMENT, which follows
         Subsection (d), and replaces it with the following:

         If all or a portion of a Guaranteed Interest Investment is surrendered
         early, such amount or amounts will be in accordance with the following:

         e)   The interest rate to be used for comparison in f) and g) below
              will be the Applicable U.S. Treasury Rate on the date of
              surrender plus .50%.

         f)   If the interest rate determined in accordance with e) above is
              equal to or less than the Guaranteed Interest Rate for the
              Guaranteed Interest Investment, there is no charge.

         g)   If the interest rate determined in accordance with e) above is
              greater than the Guaranteed Interest Rate for the Guaranteed
              Interest Investment, such charge is equal to:

              1)   the difference between such interest rate on the date of
                   surrender and the Guaranteed Interest Rate multiplied by


                                       3
<PAGE>

              2)   the number of years (including fractional parts of a
                   year) remaining in the Guarantee Period for such Guaranteed
                   Interest Investment multiplied by

              3)   the amount being surrendered.

         If the payment or transfer under this Subsection results in the
         application of all of the Investment, the amount paid or transferred
         will be equal to such Investment reduced by the amount determined under
         g) above.

         If the entire Guaranteed Interest Investment is surrendered, the
         Guaranteed Interest Investment will be reduced on the date of surrender
         and the remainder will be paid or transferred.

         If a portion of the Guaranteed Interest Investment is surrendered, the
         Guaranteed Interest Investment will be reduced by the amount being
         surrendered plus the surrender charge, if any.

8.       This rider deletes ARTICLE VII, SECTION 6- -CONTRACT AMENDMENTS,
         Subsection (c), and replaces it with the following:

         c)   As of any date after the Contract Date, we may amend or change
              the length of the Guarantee Period; the Order of Application;
              the provisions for transferring values between accounts; the
              percentage in Item (a) of Article IV, Section 4; the percentage
              contained in Article VI, Section 3; and the items included in
              the Operating Expenses for Separate Accounts under the Separate
              Account Investment Rider (if such rider is attached to this
              contract). We will give you 60 days written notice of any such
              change.

9.       By adding the following Section 6A to ARTICLE VII--GENERAL PROVISIONS:

         SECTION 6A--EXPENSE GUARANTEES.

         We charge expenses in accordance with Article Ill, but subject to
         Section 6(g)(iii) of this Article. If you choose not to accept an
         expense change, as provided in Section 6(g)(iii), the following will
         occur:

         a)   Cessation of Contributions will occur on the date specified in
              your Notification; provided, however, such date must be before
              or within the 90 day period following the date we receive such
              Notification.

         b)   Separate Account Investments will be transferred to you, if you
              are a trustee, or to the Funding Agent you tell us to, when you
              request such transfer, but in no event more than 90 days after
              the date the new expenses would otherwise take effect for this
              contract.

              If you have not designated the Funding Agent to whom funds are
              to be transferred within the 90 days after the date expenses
              changed, we will pay these funds to you, if you are a trustee
              of the Plan. If you are not Plan trustee, you must


                                       4
<PAGE>

              designate the Funding Agent to whom these amounts are to be
              transferred. Failure to designate an alternate Funding Agent
              within the time allowed by this Section will be deemed to be
              acceptance of the changed expenses for this contract.

         c)   You are not required to transfer any Guaranteed Interest
              Investments during their respective Guarantee Periods. You may
              choose to have Guaranteed Interest Investments mature under
              this contract before transferring any of such amount to another
              Funding Agent. All such amounts must be transferred to another
              Funding Agent or used to purchase annuities hereunder at the
              end of the Guarantee Period of each. The expense rate used to
              calculate expenses on each Guaranteed Interest Investment will
              remain the same as before Notification.

10.      This rider deletes the paragraph under ARTICLE VII, SECTION 14--TERM
         AND TERMINATIONS.. and replaces it with the following:

         Except as provided in Section 13 of this Article, or by any amendment
         to this contract, this contract will continue in force as long as we
         hold Investments under the contract or we are making annuity payments.
         If you transfer all of the Investments under this contract not
         associated with any annuity payments to a Funding Agent, our
         obligations under this contract will cease, except to the extent that
         we are making annuity payments. However, if we discover that we
         underpaid the Funding Agent, we will have the obligation to pay the
         appropriate amount to the Funding Agent.

11.      This rider deletes the second paragraph under ARTICLE VII, SECTION
         15--QUALIFICATION OF PLANS., and replaces it with the following:

         Notwithstanding any other provision in this contract or in any other
         agreement between you and us, if the Internal Revenue Service or a
         court makes a final determination that the Plan no longer qualifies as
         a Qualified Plan, we may require that you transfer all Investments
         invested under this contract to another Funding Agent If we decide that
         you must transfer Investments from this contract, we will send you a
         written notice describing your options. If we do not receive an
         acceptable response Notice from you within five Business Days, we will
         return the Investments held under this contract to you, or if
         appropriate, to a Plan trustee. We will not accept any Notice under

1.       DESCRIPTIONS OF THE SEPARATE ACCOUNTS. Each Separate Account is a
         pooled Separate Account for use by our retirement plan customers. The
         funds held in each Separate Account will be invested and reinvested by
         us in accordance with applicable law, without regard to any investment
         requirements of our general account assets or of any of our other
         Separate Accounts.

         A Separate Account consists of funds we receive under group annuity
         contracts or policies which permit deposit in such Separate Account and
         under which amounts are directed to such Separate Account. All income
         gains and losses (whether or not realized),


                                       1
<PAGE>

         and expenses from the assets allocated to a Separate Account will be
         credited to or charged against that Separate Account without regard
         to any other income, gains or losses, or expenses we might have for
         our general account or any other Separate Account. The assets of a
         Separate Account will not be charged with any liabilities arising
         out of the investment experience of our general account or any other
         Separate Accounts outside that Separate Account. We may occasionally
         invest the assets of any Separate Account in short term money market
         instruments, cash or cash equivalents.

         BOND AND MORTGAGE SEPARATE ACCOUNT. Bond and Mortgage Separate Account

         our general account, including bonds and mortgages from both United
         States and non-United States corporations.

         Separate Account is invested in other Separate Accounts established and
         maintained by us. The majority of the assets will be invested in other
         Separate Accounts which are invested primarily in bonds, mortgages,
         commercial paper and other fixed income type investments. The remainder
         of the assets of this Separate Account will be invested in one or more
         of our Separate Accounts invested primarily in common stocks and other
         equity investments.

         GOVERNMENT SECURITIES SEPARATE ACCOUNT. Government Securities Separate
         Account is invested primarily in obligations issued or guaranteed by

         States or foreign currency or equivalencies.

         Account is invested primarily in a broad base of stocks or other
         securities of corporations located outside the United States, but

         investments may be made in either United States or foreign currency or
         equivalencies.

         LARGE COMPANY BLEND SEPARATE ACCOUNT. Large Company Blend Separate
         Account is invested primarily in common stocks from large, established
         companies whose stock exhibits a combination of substantial value and
         good earnings growth potential. The investments may also include
         derivative instruments such as options and futures, other equity
         securities, or other convertible securities that may be converted to

         futures, other equity securities or other convertible securities that

         market. The investments may also include derivative instruments such as
         options and futures, other equity securities or other convertible
         securities that may be converted to common stocks. If the market as a

         investments may also include derivative instruments such as options
         and futures, other equity securities, or other convertible

         invested primarily in bonds, mortgages, commercial paper and other
         fixed income type investments.

         STOCK INDEX 500 SEPARATE ACCOUNT. Stock Index 500 Separate Account is
         invested primarily in stocks and securities of companies whose stocks

         longer calculated). The investments may also include a reasonable
         amount of stock index futures, commercial paper, derivative securities
         and other types of investments. In addition, some funds may be invested
         in stock index accounts operated by other investment managers. Stock

         options and futures, other equity securities or other
         convertible securities that may be converted to common STOCKS.
         The U.S. Stock Separate Account is managed by looking for shifts in
         the economy, industries that stand to benefit from those shifts,
         and companies in those industries that are undervalued by the market.

2.       DETERMINING SEPARATE ACCOUNT VALUES; OPERATING EXPENSES. The value of a
         Separate Account is its market value (appraised market value for Real
         Estate Separate Account) less Operating Expenses, if any. If there is
         no readily available market, its value is the fair market value of the
         assets held in such Separate Account as determined by us using
         generally accepted accounting practices and applicable law. The


                                       4
<PAGE>

         value of all Separate Accounts will always be expressed in U.S.
         dollars. We will determine the value of a Separate Account on each
         Valuation Date.

         OPERATING EXPENSES are those charges which must be paid in order to
         operate a Separate Account or obtain investments for a Separate
         Account. Operating Expenses include, but are not limited to, custodial
         fees, transfer taxes, brokerage fees, processing fees, and other taxes
         and fees associated with the operation of a Separate Account. Operating
         Expenses will be deducted from the Separate Account associated with a
         particular charge on the next Valuation Date after the Operating
         Expenses have been paid or are immediately payable. In accordance with
         our then-current procedures, various Separate Accounts may share in the
         payment of certain Operating Expenses and, in some cases, we may use
         certain fees paid to us by third parties to offset Operating Expenses
         incurred by a Separate Account which would otherwise be payable from
         that Separate Account.

         VALUATION DATE means the date we determine the value of a Separate
         Account Valuation Dates will occur on dates we determine, but at
         least on the last Business Day of a calendar month. Valuation will
         occur at the end of each such day, according to our then-current
         procedures. For purposes of the International Stock Separate
         Account, International Small Company Separate Account, and
         International Emerging Markets Separate Account, only those days on
         which both the value of the underlying investments is determined and
         we are open for business will be Valuation Dates.

3.       MANAGEMENT CHARGES. The Management Charge under each Separate Account
         will be a percentage of the value of assets in such Separate Account,
         subject to the equivalent of a maximum annual percentage listed in the
         Table of Separate Account Features. We reserve the right to change the
         Management Charge to any charge up to the maximum limit at any time by
         giving you written notice at least 30 days before the date the change
         is to take effect.

         MANAGEMENT CHARGE means the charge consisting of the investment
         management charge and the contract expense charge applicable to this
         class of contracts for each Separate Account.

         The assets of Bond Emphasis Balanced Separate Account and Stock
         Emphasis Balanced Separate Account will pay Management Charges under
         our other Separate Accounts in which they are invested. An additional
         Management Charge will be charged under these Separate Accounts only
         for management services actually performed exclusively for assets held
         in these Separate Accounts.

         A prorata charge will be deducted from each Separate Account on each
         Valuation Date for the number of calendar days within the Valuation
         Period ending on such Valuation Date.

         VALUATION PERIOD means the period from the end of a Valuation Date to
         the end of the next following Valuation Date.


                                       5

4.       SEPARATE ACCOUNT INVESTMENT. A Separate Account Investment is
         established for each Member for a Separate Account for each type of
         Contribution a Member directs to a Separate Account.

         Where Money Market Separate Account is available and we receive
         Notification from you to do so, an Unallocated Separate Investment
         Account will be established for Contributions for which either i) we do
         not have all the necessary information needed to allocate such
         Contributions to individual Members, or ii) you have notified us that
         such Contributions are to be unallocated. If Money Market Separate
         Account is not available, an Unallocated Contribution Investment will
         be established, using a Guaranteed Interest Investment with the
         shortest Guaranteed Period available.

         UNALLOCATED SEPARATE ACCOUNT INVESTMENT means the Investment
         established to hold unallocated Contributions, invested in Money Market
         Separate Account, if available, and operates as if it were a Member's
         Investment.

5.       RETURNS CREDITED TO SEPARATE INVESTMENT ACCOUNTS. Each Separate Account
         Investment established under this contract will be credited with its
         portion of the return associated with the appropriate Separate Account.
         The return for a Separate Account will be based on the change in value
         of that Separate Account less any Management Charge.

         In order to track the returns for the Separate Account Investments
         established under this contract, we will use a unit value system of
         recordkeeping, unless we determine that another recordkeeping system
         would be more appropriate.

6.       UNIT VALUE SYSTEM OF RECORDKEEPING. Under a unit value system of
         recordkeeping, we will calculate the value of a Separate Account
         Investment for each Valuation Date by multiplying the number of
         Separate Account units held in the Separate Account Investment by the
         applicable Unit Value. A Unit Value is the dollar value for one unit.

         Contributions or transfers to a Separate Account Investment increase
         the number of Separate Account units credited to it. Transfers and
         payments from a Separate Account Investment reduce the number of
         Separate Account units. The increase or decrease in the number of
         Separate Account units is calculated by dividing the dollar amount of
         the contribution, transfer, or payment by the applicable Unit Value.

         We will calculate the Unit Value applicable to each Separate Account
         Investment on each Valuation Date. The Unit Value will be based upon
         the total value of the Separate Account and the number of existing
         Separate Account units.

         When crediting Contributions and transfers added to a Separate Account
         Investment we will use the Unit Value applicable to the Separate
         Account Investment for the Valuation Date on which we accept the
         Contribution or transfer. If we accept the Contribution or transfer on
         a date other than a Valuation Date, we will use the Unit Value for the
         next following Valuation Date.


                                       6

7.       DEPOSITS TO SEPARATE ACCOUNTS; RESTRICTIONS AND ORDER OF ENTRY. We
         reserve the right to defer or stop your ability to direct Contributions
         and transfers to a Separate Account, and we may require you to transfer
         existing account balances out of a Separate Account. We may exercise
         these rights if we

         a)   need to comply with regulation, statute, or decisional law to
              which we are subject,

         b)   believe it would be imprudent not to do so in fulfilling our
              fiduciary role as an investment advisor under ERISA,

         c)   believe the investment approach of the Separate Account no
              longer makes sense, is excessively expensive, or does not
              currently have any favorable investment opportunities
              available, or

         d)   if, in our opinion, continued operation of the Separate Account
              is inappropriate.

         Contributions or transfers directed to a Separate Account that we have
         closed on a temporary or permanent basis will be directed to Money
         Market Separate Account, if available, or to the Guaranteed Interest
         Investment with the shortest Guarantee Period available under the
         contract. If the Separate Account has been closed on a temporary basis,
         we will treat a Contribution or transfer request as a Notification that
         money should be transferred to the closed Separate Account as soon as
         permitted under the terms of the contract.

         PROVISIONS FOR A TEMPORARILY CLOSED SEPARATE ACCOUNT. We have
         established the following order of entry into a Separate Account that
         was temporarily closed, then reopened:

         a)   All amounts held in Money Market Separate Account waiting for
              transfer to the Separate Account.

         b)   Any amounts held in any other Separate Account or in our
              general account which are to be transferred to the Separate
              Account.

         Within each of the above 2 categories, funds will be transferred one
         customer at a time, in order from the oldest waiting Notification to
         the newest Notification.

         Normally, if the amount of the intended transfer is greater than the
         amount open for acceptance by a previously closed Separate Account, the
         entire amount of the transfer will continue to be held in the account
         it was at the time of the request until the Valuation Date when
         complete transfer may be made. However, we and you (the Member, if
         permitted by the Plan) may mutually agree to transfer only a portion of
         the intended amount to the Separate Account.

         We will notify you in writing when amounts have been transferred to
         a reopened Separate Account.


                                       7
<PAGE>

         You or a Member, as permitted by the Plan, may revoke a request for
         transfer of funds to a Separate Account by giving us Notification
         before the date transfer is made. The Notification must also include
         new investment directions for the intended transfer.

         PROVISIONS FOR A PERMANENTLY CLOSED SEPARATE ACCOUNT. We will notify
         you in writing of our intent to permanently close a Separate Account
         You will have 60 days to request transfer as described in 8. BELOW. If
         after 60 days we have not received Notification of where to transfer a
         closed Separate Account balance, we will treat the account as a
         Contribution for which we do not have investment direction.

8.       TRANSFERS AND PAYMENTS FROM A SEPARATE ACCOUNT INVESTMENT. We will,
         upon Notification from you (the Member if permitted by the Plan), and
         subject to our right to defer a transfer or payment as described in
         Section 9,

         a)   transfer to the Member's Guaranteed Interest Investment or
              another Separate Account Investment all or any portion of the
              Separate Account Investment specified, or

         b)   transfer to another Funding Agent all or any portion of the
              Member's Separate Account Investment, or

         c)   pay the Member an amount equal to all or any portion of the
              Member's Separate Account Investment.

         The amount to be paid or transferred will be determined and paid or
         transferred within seven Business Days after (i) the Valuation Date on
         which we receive the Notification, or (ii) a later Valuation Date
         specified in the Notification. Payments and transfers will be made in
         accordance with our then-current procedures. We will notify you in
         writing of these procedures. The amount transferred or paid will be
         deducted from the Separate Account Investment from which such transfer
         or payment was requested on the date of such transfer or payment. Each
         transfer to another Separate Account Investment may occur only on a
         Valuation Date of that Separate Account.

         We are not responsible for the application of amounts transferred to
         another Funding Agent.

9.       LIMITATIONS ON TRANSFERS AND PAYMENTS FROM A SEPARATE ACCOUNT
         INVESTMENT. In general, transfers and payments from a Separate
         Account Investment will be made within seven Business Days after the
         first Valuation Date following the request specified in Section 8 of
         this rider. We reserve the right, however, to defer such transfers
         or payments up to the maximum number of days shown in the Table of
         Separate Account Features for each Separate Account. If we defer any
         transfer or payment under this Section, we will determine the amount
         to be transferred or paid on the date transfer or payment occurs. We
         will notify you in the event of any deferment of more than 30 days
         under the provisions of this Section.


                                       8

         These limitations will not apply to the payments to the beneficiary of
         a Member due to the Member's death, payments to a Member due to
         disability or retirement under the Plan and to purchases of annuity
         under Article IV, Section 2 of the contract.

         SPECIAL REAL ESTATE LIMITATIONS. Because of the illiquid nature of the
         assets in which Real Estate Separate Account is invested, we reserve
         the right to defer transfers or payments from a Real Estate Separate
         Account Investment if a transfer or payment would exceed the amount of
         cash and other liquid assets held in Real Estate Separate Account,
         reduced by amounts committed to purchase properties or needed for
         Operating Expenses.

         Real Estate Separate Account may be illiquid for indefinite periods of
         time. We will not manage Real Estate Separate Account to provide a
         liquidity pool for requests for transfer or payment. If requests for
         transfer or payment from Real Estate Separate Account are deferred,
         then the deferred transfers or payments, when made, will be made in the
         following order:

         a)   Any death benefits payable under a defined contribution plan.

         b)   All or a portion of each of the other requests for payment,
              determined as follows:

              i)   the amount of the request, divided by

              ii)  the amount of all waiting requests, multiplied by

              iii) amount we determine to be available to pay requests;
                   provided, however, that no more than the amount of
                   the request shall be paid out.

         Deferred transfers or payments, when paid, will be made as of a
         Valuation Date and will be based on the Real Estate Separate Account
         Unit Value as of the date paid. In determining the amount available to
         pay requests, we will subtract amounts payable under any other group
         annuity contract which requires that we make payments from the Real
         Estate Separate Account using a method other than the one described in
         this Section.

         We reserve the right to make payments in a different manner than
         described in this Section if we (i) are required to do so under
         applicable statutes, regulations, or decisional law to which we are
         subject, (ii) must do so to comply with our fiduciary responsibilities
         as an ERISA investment manager as described in Article II, Section 8,
         or (iii) deem it necessary to make a change to maintain an equitable
         distribution of assets under all of our group annuity contracts. We
         will not implement a change under item (iii) before the notice to all
         affected contractholders is provided and the appropriate time period
         after the notice has elapsed.

         SPECIAL LIMITATION FOR CERTAIN SEPARATE ACCOUNTS. We reserve the right
         to make the portion of a requested transfer in excess of the specified
         dollar limit in substantially equal monthly installments over a period
         not to exceed the specified period, if, in the specified period which
         ends on the requested date of transfer, all transfers and payments from
         the total of all Separate Account Investments invested in a particular
         Separate Account which is subject to the dollar limit total the
         specified dollar limit or more. For purposes of this


                                       9
<PAGE>

         limitation, transfers and payments from any other Separate Account
         investments or funds included in the Separate Account from any other
         contracts or policies issued in connection with the Plan or with any
         other retirement plan of the Employer will be included as a transfer
         or payment from a Separate Account Investment. If this limitation is
         imposed by us, the first installment will be made one month after
         the date of request, or on such later date that you specify. The
         specified dollar limit and period are:

         a)   $1,000,000 and twelve months, respectively, for International
              Stock Separate Account, International Small Company Separate
              Account, International Emerging Markets Separate Account, and
              Stock Index 500 Separate Account.

         b)   $20,000,000 and 36 months, respectively, for Bond Emphasis
              Balanced Separate Account, Government Securities Separate
              Account, Large Company Blend Separate Account, Large Company
              Growth Separate Account, Large Company Value Separate Account,
              Medium Company Blend Separate Account, Medium Company Growth
              Separate Account, Medium Company Value Separate Account, Small
              Company Blend Separate Account, Small Company Growth Separate
              Account, Small Company Value Separate Account, Stock Emphasis
              Balanced Separate Account, and U.S. Stock Separate Account.

10.      PLANS WHICH MAY INVEST IN THE SEPARATE ACCOUNTS. The Separate
         Accounts are not registered with the federal Securities and Exchange
         Commission and therefore only Plans which meet certain requirements
         under the Code may invest in the Separate Accounts. If the Internal
         Revenue Service or a court makes a final determination that the Plan
         no longer qualifies as a Qualified Plan, we will require that you
         transfer any assets invested in the Separate Accounts. If we decide
         that you must transfer assets from the Separate Accounts, we will
         send you a notice describing your options. Your Notification must
         clearly specify the Guaranteed Interest Investment(s) or the Funding
         Agent to which you want the assets transferred. If we do not receive
         an acceptable Notification from you within 5 Business Days, we will
         transfer the assets to the Guaranteed Interest Investment with the
         shortest duration.

11.      FUNDS. We are the sole owner of all assets held in the Separate
         Accounts.

Minimum incomes for purchases made within the five- year period beginning
January 1, 2000, will be 97% of the incomes purchased under the above basis.
Minimum incomes for purchases made within any subsequent five-year period will
be 97% of the incomes for the preceding five-year period. The minimum amounts of
annuity available at other ages and for other forms of income will be determined
by us based on the same basis as the above. We will make these available to you
on request.

SUBSECTION (3)--CANCELLATION OF ANNUITY. If, under the provisions of the Plan in
effect on the Member's Annuity Start Date, you determine and report to us that
the annuity purchased for a Member is to be reduced, then the fraction you
report will be cancelled and the amount of annuity payments paid to the member,
the beneficiary or contingent annuitant will be reduced accordingly.

The reserve for any annuity cancelled under this Section will be applied in
accordance with Article II, Section 5.

SUBSECTION (4)--MISSTATEMENTS. If the age or any other relevant fact of any
Member or contingent annuitant is found to have been misstated, the amount of
annuity payable by us will be that provided by the amount applied to provide
such annuity, determined as of the date established by the misstated information
and on the basis of the correct information. Any overpayment by us resulting
from any misstated information will be deducted from amounts thereafter payable
to a Member, the contingent annuitant or the beneficiary. Any underpayment by us
resulting from any misstatements will be paid in full with the next payment due
the Member, the contingent annuitant or beneficiary.

SUBSECTION (5)--COMMUTATION OF PAYMENTS. If any annuity payments are to be
commuted, the commuted value of the payments will be determined by us, using the
interest rate which was used as a basis for calculating the amount of the
payments at the time the annuity was purchased.

Neither the Member, the contingent annuitant nor any beneficiary who is a
natural person taking in his or her own right has the right to commute any
annuity payments under this contract

SECTION 3--SINGLE SUM PAYMENTS.

If permitted by the Plan, a Member who has reached a Benefit Event may elect a
single sum payment equal to all or a portion of the Member's Account. Any single
sum payment made under this Section will be an application of the Member's
Account on the date paid.

Any single sum payment to a Member is subject to the delay of payment and
limitation provisions of Article VI, Section 4 and the Separate Account
Investment Rider, if any. Such amount may also be subject to the charge in
Article VI, Section 3, unless such payment is made within:

         a)       60 days after we send notification to the Member of the
                  options available under the contract upon reaching the first
                  Benefit Event under the Plan, other than death, or

                                       12
<PAGE>

         b)       60 days after a Member's Normal Retirement Date, if such date
                  is later than the date in (a) above, or

         c)       120 days after we send notification to the beneficiary of the
                  options available under the contract, in the event of the
                  death of the Member.

SECTION 4--FULL FLEXIBILITY OPTION.

This option provides scheduled installment payments, starting within twelve
months of the date of the Notification and continuing until the date the Account
is exhausted. Payments to the Member or beneficiary are subject to the
distribution rules contained in the Code and the regulations thereunder.

We will pay a portion of such Account on the date or dates requested each
calendar year and continuing until the entire Account has been paid. This amount
is the scheduled amount. The unpaid portion of the Account will continue to be
credited with separate account performance under the terms of the Separate
Account Investment Rider or the interest rate otherwise available and as may be
reduced as provided in Article III, Section 5.

The Order of Application will determine from which Investments payments will be
made. However, a Member or beneficiary may give us Notification of a different
order if a different order is desired. If we receive such Notification, payments
from Guaranteed Interest Investments will be subject to the charge in Article
VI, Section 3, and the delay of payment and limitation provisions of Article VI,
Section 4 and the Separate Account Investment Rider.

If scheduled payments in any calendar year exceed the maximum amount, the excess
amount will be subject to the charge in Article VI, Section 3, and the delay of
payment and limitation provisions of Article VI, Section 4 and the Separate
Account Investment Rider. For any calendar year, the maximum amount is the
greatest of:

         a)       13% of the Account balance at the beginning of the current
                  calendar year.

         b)       the Account balance at the beginning of the current calendar
                  year divided by the number of years of the Member's or
                  beneficiary's life expectancy.

         c)       the amount withdrawn in the preceding calendar year which was
                  not subject to the charge in Article VI, Section 3.

In addition to the scheduled payments, nonscheduled payments may be requested.
We may establish a minimum dollar amount for nonscheduled payments. Nonscheduled
payments may be subject to a transaction fee. Nonscheduled payments will be
subject to the charge in Article VI, Section 3, and the delay of payment and
limitation provisions of Article VI, Section 4 and the Separate Account
Investment Rider.

The Member or beneficiary may request termination of the Full Flexibility Option
by one or more of the following methods: (i) requesting an excess payment equal

requesting that the Full Flexibility Option be cancelled and leaving the
remaining balance under this contract.

SECTION 5--MODIFICATION IN MODE OF PAYMENT OF INCOME.

under the Full Flexibility Option, the monthly amount of income payable under
this contract to such Member or to the beneficiary or contingent annuitant would
be less than $20, we may, at our option, pay such amount less frequently, but
not less frequently than annually.

SECTION 6--FACILITY OF PAYMENT.

If any Member, alternate payee, contingent annuitant or beneficiary becomes
physically, mentally or legally incapable of accepting any payment and the
person has no legal representative or guardian who can accept the payment on the
person's behalf, we may, in the absence of Notification from you, at our option,
make such payment to the person or persons as have, in our opinion, assumed the
care and principal support of the Member, contingent annuitant or beneficiary.
However, any payment due a minor will be paid at a rate not exceeding the
greater of (i) $100.00 per month or (ii) the maximum amount permitted by the
laws of the state of issue of this contract In no event will any such payment
exceed the maximum amount allowed under applicable law of the state of issue of
this contract. In no event will any such payment exceed the maximum amount
allowed under applicable law of the state in which this contract is delivered.
Any such payment made by us will fully discharge us to the extent of the
payment.

SECTION 7--ASSIGNMENT.

Except for an assignment to an alternate payee required by a Qualified Domestic
Relations Order, no benefits payable under this contract to any Member,
beneficiary or contingent annuitant are assignable, and all such benefits are
exempt from the claims of creditors to the maximum extent permitted by law.

         a)       The Plan must allow the Member to receive the withdrawal.

         b)       The Notification must be on a form we either furnish or

         c)       Any amount withdrawn under this Section will be subject to

Upon Notification to us at our Corporate Center, payment of the aggregate of all
of the Guaranteed Interest Investments and Separate Account Investments will be

Section 3 of this Article, and the limitations provided in Section 4 of this
Article and the Separate Account Investment Rider, if any, the amount of any

SECTION 2--CESSATION OF CONTRIBUTIONS.

Cessation of Contributions will be effective as of any of the following dates:

         a)       On the date you give us written Notification that
                  Contributions will cease.

         b)       On the date the Plan terminates.

         c)       On or after the date on which the Internal Revenue Service or
                  a court makes a final determination that the Plan no longer
                  meets the requirements to remain a Qualified Plan, if we have
                  given you written notice that cessation will occur on that
                  date or at some later date.

         d)       On the date no Accounts remain under this contract.

Upon cessation of Contributions, no employees will become Members and no further

All provisions of this contract will remain effective as to any Accounts which
have not been paid or applied in full.

Once all Accounts have been paid or applied in full, we will have no further
obligation under this Contract as to those Accounts.

SECTION 3--CHARGES FOR EARLY SURRENDER OF A GUARANTEED INTEREST INVESTMENT.

If a Member transfers or withdraws all or a part of a Guaranteed Interest
Investment before the end of its Guarantee Period, the transfer or withdrawal is
a surrender of that amount. Transfer or withdrawal of an Investment refers to
transactions from Guaranteed Interest Investments under any of the following
contract provisions:

         a)       1 Transfer between Investments, Article II, Section 6.

                                       16
<PAGE>

         b)       A single sum payment under Article IV, Section 3, after the
                  periods specified in such Section.

         c)       A withdrawal under Article V, Section 1.

         d)       A transfer to another Funding Agent under Article VI,
                  Section 1.

         We reserve the right to waive this charge for certain withdrawals. Any
         such waiver will be applied in a uniform manner to all such withdrawals
         from contracts of this class.

         If all or a portion of a Guaranteed Interest Investment is surrendered
         early and the Guaranteed Interest Rate in effect for contracts of this
         class for the date of surrender is greater than the Composite
         Guaranteed Rate for the Investment, the amount available will be
         reduced by a surrender charge equal to the following:

         e)       The difference between such Guaranteed Interest Rate in effect
                  for new Contributions for the date of surrender and the
                  Composite Guaranteed Rate of the Investment being surrendered,
                  multiplied by

         f)       The number of years (including fractional parts of a year)
                  remaining in the Guarantee Period for the Guaranteed Interest
                  Investment, multiplied by

         g)       The amount being surrendered.

If the entire Guaranteed Interest Investment is surrendered, the Guaranteed
Interest Investment will be reduced on the date of surrender and the remainder
will be paid or transferred.

If a portion of the Guaranteed Interest Investment is surrendered, the
Guaranteed Interest Investment will be reduced by the amount being surrendered
plus the surrender charge, if any.

If the Guaranteed Interest Rate in effect for contracts of this class for the
date of surrender is equal to or less than the Composite Guaranteed Rate for
such account, there is no surrender charge.

SECTION 4--LIMITATIONS ON TRANSFERS AND PAYMENTS FROM GUARANTEED INTEREST
INVESTMENTS.

         a)       In general, payments and transfers from the Guaranteed
                  Interest Investments will be made in full within seven
                  Business Days after the requested date of payment. However, we
                  reserve the right to defer any payment or transfer under this
                  contract up to 270 days. These delay rights will not apply to
                  payments to the beneficiary named by the Member, payments to a
                  Member due to disability or retirement under the Plan or to
                  purchases of annuity under Article IV, Section 2.

                  Such deferment will be based on unstable or disorderly market
                  or investment conditions which, in our opinion, do not allow
                  for an orderly investment transfer. This deferment may
                  include, but not be I limited to, situations where regular
                  banking has been suspended or when an emergency or other
                  circumstances



                                       17
<PAGE>

beyond our control do not allow for the orderly
                  disposal and liquidation of securities or other assets.

         b)       We reserve the right to make the portion of the requested
                  payment or transfer in excess of the greater of

                  i)       25% of the aggregate  Guaranteed Interest
                           Investments under the contract on the date 12
                           months prior to such determination date, or

                  ii)      $25,000,000  in the 12 month  period  which  ends on
                           the date of requested payment or transfer,

                  in substantially equal monthly installments over a period not
                  to exceed 36 months. For purposes of this limitation, payments
                  and transfers at investment value from our general account
                  from any other contracts or polices we issued in connection
                  with the Plan will be included as a payment or transfer from
                  the Guaranteed Interest Investments under this contract

                  If this limitation is imposed by us, we will make the first
                  installment one month after the date of request, or on the
                  date specified in your Notification.

                  These delay rights will not apply to payments to the
                  beneficiary named by the Member, payments to a Member due to
                  disability or retirement under the Plan or to purchases of
                  annuity under Article IV, Section 2.

If we defer any payment or transfer under this Section, we will determine the
amount to be paid or transferred on the actual date of payment or transfer. We
will notify you if the deferment will be more than 30 days. During any
deferment, requested funds will continue to earn interest at the same rate.


                                       18

ARTICLE VII--GENERAL PROVISIONS

SECTION 1--CERTIFICATES.

If a Member contributes under the Plan and the state of issue so requires, we
will prepare, for delivery to each such Member, an individual certificate
setting out a statement of the benefits to which that Member is entitled and to
whom death benefits are payable. If benefits become payable to a Member under
one of the options of Article IV, we will issue an individual certificate
setting forth the amount, form and period of payment of the annuity benefits.

SECTION 2--BENEFICIARY.

The beneficiary is the person or persons named by the Member to whom benefits
(other than any annuity payable to a contingent annuitant under the provisions
of Article IV, Section 2) are payable under this contract upon the death of the
Member, subject to the provisions of Article IV, Section 7. A Member will name
or change a beneficiary by filing a written beneficiary designation to that
effect with us in a form acceptable to us. Any beneficiary designation will not
have any effect until we receive it. When we receive the designation, it will be
effective as of the date it is executed by the Member, but any payments we made
before receipt of the designation will discharge us to the extent of such
payments. We reserve the right to require the Member's certificate for
endorsement of any change of beneficiary. Unless prohibited by the Plan or by a
prior beneficiary designation, any person receiving benefits or payments which
might continue beyond that person's life time may designate a beneficiary to
receive any remaining payments.

Unless otherwise specified by the Member with our consent,

         a)       if any beneficiary dies before the Member, any payment which
                  would have become payable to such beneficiary, if living, will
                  be payable when due to the beneficiary or beneficiaries
                  surviving the Member in the order provided.

         b)       if any beneficiary survives the Member but dies before
                  receiving all of the payments which would have been payable to
                  such beneficiary, if living, payment will be paid when due to
                  the surviving beneficiary or beneficiaries in the order
                  provided.

         c)       if the last survivor of all named beneficiaries dies after the
                  death of the Member (and the contingent annuitant, if any) and
                  before all payments due the beneficiary have been made, the
                  remaining payments will be commuted and the commuted value
                  paid to the executor or administrator of the estate of such
                  last survivor.

If no named beneficiary survives the Member (and the contingent annuitant, if
any), or no beneficiary has been named, any amount which would have become
payable to a beneficiary will be commuted and the commuted value paid to the
executor or administrator of the estate of the Member (the executor or
administrator of the estate of any contingent annuitant, if he survives the
Member). If no formal estate is created, we may pay out any benefits In
accordance with any state or federal law which permits us to make payments to
specific persons without the creation



                                       19
<PAGE>

of a formal estate. If state or federal law requires that we make any payments
only to a formally established estate, we will make payments in accordance with
that law.

If required by the facts surrounding a particular death or deaths, we may use
the appropriate state statute dealing with simultaneous or nearly simultaneous
deaths to determine who will be treated as a survivor entitled to receive
benefits. If no state law applies, then we may rely upon the most current
version of the uniform Simultaneous Death Act to make that determination.

If the beneficiary is not a natural person taking in his or her own right (that
is, a trust or an estate), any monthly or other periodic payments will be
commuted and the commuted value paid to the beneficiary in a single sum.
However, if the beneficiary is a trust established for the benefit of a natural
person and if the payment period is at least 24 months and not more than 60
months, monthly or other periodic payments may be continued to such beneficiary
for any period which is not prohibited by the Code.

SECTION 3--DIVIDENDS.

Because of the direct crediting of investment return to both Guaranteed Interest
Investments and Separate Account Investments, it is not anticipated that there
will be any surplus accruing on this contract from which dividends may be
apportioned to this contract. However, if a dividend is declared, any portion of
the divisible surplus that we determine to accrue on this contract will be
determined annually by us and will be credited to this contract on the first day
of each Deposit Year after the Contract Date. Any dividend will be applied as
directed by you in accordance with Plan provisions.

SECTION 4--PLAN AND PLAN AMENDMENTS.

You agree to furnish us with a copy of the Plan in effect on the Contract Date
and any subsequent amendments to it. No amendment to the Plan or interpretation
of the Plan language which affects our duties and obligations will have any
effect on the terms of this contract, unless: (i) we have received timely notice
of the amendment or interpretation, and (ii) we have not sent you a written

our receipt of the amendment or interpretation.

                  give you written notice of any such change.

                  any such change.

         d)       We may amend or change the annuity purchase basis shown in
                  Article IV, Section 2, as follows:

                  i)       For Account values accumulated during the five year
                           period beginning on the Contract Date, no change will
                           be made in such purchase rate basis.

                  ii)      For Account values accumulated after the date which
                           is five years after the Contract Date, we may amend
                           or change such basis on any date which is later than
                           (I) five years after the Contract Date or (ii) five

                  Generally, we will indicate that you use one or more of the
                  following methods to agree to our proposed amendments:

                           us. We will usually propose the use of this method
                           for procedural amendments or amendments which
                           increase your rights rather than changes which limit

                  conclusive on each Member, beneficiary, or contingent

instructions which we in good faith believe are valid, if we receive such
instructions from you, a Plan trustee, a Plan administrator, a Plan fiduciary,
or, if the Plan permits, a Member, alternate payee, contingent annuitant or
beneficiary. If we follow such instructions, we will have no further obligations
with respect to the amounts paid out or the actions taken. If we believe in good
faith that the law requires us not to follow an apparently valid instruction, we
are not required to act on any instruction.


                                       22

SECTION 10--SINGLE PAYMENT.

We will make any payment to a Member, contingent annuitant, alternate payee or
beneficiary in accordance with any withdrawal or payment option available under
the contract only once. Any payment we make in accordance with any withdrawal or
payment option will be in lieu of any other benefit or withdrawal option and
will extinguish any claim by any Member, contingent annuitant, alternate payee
or beneficiary to receive the amount paid out.

SECTION 11--OVERPAYMENT.

In the event that we make an overpayment of any amount payable to a Funding
Agent, Member, contingent annuitant, alternate payee or beneficiary, we will
have the option to seek reimbursement of that overpayment from the individual
receiving the overpayment. If the overpayment resulted from any action by you
and we suffered a loss as a result of our good faith reliance upon your action,
you will pay us an amount equal to the overpayment

SECTION 12--OWNERSHIP.

You are the owner of this contract. However, if the Plan is trusteed and this
contract is issued to the trustee(s), the trustee(s) of the Plan is sole owner
of all the payments, rights, options, and privileges herein granted or made
payable to any Member, beneficiary, or contingent annuitant under this contract.
This includes, without limitation, the right to distribute all or a portion of
the Member's Account, or ownership of these rights in respect of such Account,:
on or after the Member's termination of employment. However, this does not
include the right to designate a Member's beneficiary unless such right has been
granted to the trustee by the Plan or trust. The trustee(s) of the Plan is
entitled to exercise all such rights, options, and privileges and to receive all
such payments at the time or times specified in this contract that such
payments, rights, options, and privileges are available to a Member. Such
exercise by the trustee(s) may be made without the consent or participation of
any Member, beneficiary or contingent annuitant.

SECTION 13--TERMINATION AND CASH OUT OF CONTRACT.

We may begin cash out proceedings with regards to the funds held under this
contract on or after the date we have announced we will refuse all further
contributions under contracts of this class, subject to the following:

         a)       We have announced our intention to refuse further
                  Contributions and that we will no longer write or accept
                  applications for contracts of this class.

         b)       Once we determine we wish to cash out contracts of this class,
                  we will cash out all contracts of this class without
                  exception.

         c)       Amounts held in any of our Separate Accounts will be available
                  for payment or transfer in accordance with the contract
                  provisions or riders making such Separate Accounts available
                  hereunder.

         d)       For funds held in our general account, the following will
                  apply:


                                       23
<PAGE>

                  i)       You may choose to transfer such funds to another
                           Funding Agent. No charge will be made under Article
                           VI, Section 3, for any funds so transferred.

                  ii)      If no other Notification is received by us, at the
                           end of any Guarantee Period, we will treat the funds
                           held in our general account as if they are being held
                           under the group annuity contract then offered by us
                           which, in our opinion, most closely parallels the
                           provisions of this contract Thereafter, the
                           provisions of this contract will no longer apply.

                  iii)     There will be no charge made for payment from this
                           contract of single sum amounts at recognized benefit
                           events, even if the group annuity contract described
                           in item (d) (ii) above would not permit such pay out
                           without charge.

         e)       The annuity purchase rate guarantees in effect under this
                  contract on the day before the provisions of item (d) (ii) of
                  this Section are instituted will remain the purchase rate
                  guarantees for any general account funds handled in accordance
                  with item (d) (ii).

                  Such purchase rate guarantees will also remain in effect for
                  any Separate Account funds held hereunder until paid or
                  transferred.

         f)       We will not change any Composite Guaranteed Rate for amounts
                  held in our general account before the end of the Guarantee
                  Period for such amounts.

         g)       Your right to transfer funds held hereunder to another Funding
                  Agent will not be changed.

         h)       If we choose to make another group annuity contract available
                  to other contractholders of this type of contract, we will
                  make such a group annuity contract available to you.

         i)       We will give you 60 days advance  written  notice  before we
                  will enforce the  provisions of this Section.

SECTION 14--TERM AND TERMINATION.

Except as provided in Section 13 of this Article, or by any amendment to this
contract, this contract will continue in force as long as we hold assets for you
or are making annuity payments. If you transfer all of the assets under this
contract not associated with any annuity payments to a Funding Agent, our
obligations under this contract will cease, except to the extent that we are
making annuity payments. However, if we discover that we underpaid the Funding
Agent, we will have the obligation to pay the appropriate amount to the Funding
Agent.

                                       24

SECTION 15--QUALIFICATION OF PLANS.

We assume no responsibility for ensuring that the Plan remains a Qualified Plan
or meets any of the requirements of the Code or ERISA. While we will undertake
those duties described in this contract or in the service agreement in a manner
which should help you to meet the requirements of the Code and ERISA, you agree
and acknowledge that we do not have final responsibility for making sure that
you take all appropriate steps needed to keep the Plan in compliance with the
Code and ERISA.

Notwithstanding any other provision in this contract or in any other agreement
between you and us, if the Internal Revenue Service or a court makes a final
determination that the Plan no longer qualifies as a Qualified Plan, we may
require that you transfer all assets invested in this contract to another
Funding Agent. If we decide that you must transfer assets from this contract, we
will send you a written notice describing you options. If we do not receive an
acceptable response Notice from you within five Business Days, we will return
the money held under this contract to you, or if appropriate, to a Plan trustee.
We will not accept any Notice under this Section unless the Notice dearly
specifies the Funding Agent to receive the assets.

SECTION 16-OUR RELATIONSHIP TO THE PLAN.

Notwithstanding any other provision in this contract or in any other agreement
between you and us, with respect to the Plan (i) except as described in Article
II, Section 8, we act only as a service provider, and (ii) we do not act as a
Plan trustee, Plan fiduciary, or Plan administrator under ERISA or any state
law. In addition, we do not practice law and do not give any individual legal
advice to you or your Plan.

Nothing in this contract shall amend any provision of the Plan nor shall any
provision of the Plan act as an amendment to this contract. Moreover, no
provision or option available under this contract shall be available unless that
provision or option is permissible under the Plan.
