        options and transfer amounts among these options as your

        partial surrenders or a full surrender.

NOTES
- --------------------------------------------
</TABLE>
    
 
   
(1) A portion of the brokerage commissions that certain funds pay was used to
reduce fund expenses. In addition, certain funds, or FMR on behalf of certain
funds, have entered into arrangements with their custodian whereby credits
realized as a result of uninvested cash balances were used to reduce custodian
expenses. The total operating expenses, after reimbursement for Index 500
Portfolio reflect these reductions in the above table.
    
 
   
(2) Neuberger Berman Advisers Management Trust is divided into portfolios
("Portfolios"), each of which invests all of its net investable assets in a
corresponding series ("Series") of Advisers Managers Trust. The figures reported
under "Management Fees" include the aggregate of the administration fees paid by
the Portfolio and the management fees paid by its corresponding Series.
Similarly, "Other Expenses" include all other expenses of the Portfolio and its
corresponding Series.
    
 
   
(3) Expenses reflect expense reimbursement. Neuberger Berman Management, Inc.
(NBMI) has undertaken to reimburse certain operating expenses, including the
compensation of NBMI and excluding taxes, interest, extraordinary expenses,
brokerage commissions and transaction costs, that exceed, in the aggregate, 1%
of the Mid-Cap Growth Portfolio's average daily net asset value. Absent such
reimbursement, the Total Annual Expenses for the year ended December 31, 1998
would have been 1.43% for the Mid-Cap Growth Portfolio. These expense
reimbursement agreements are subject to termination upon 60 days written notice
with respect to the Mid-Cap Growth Portfolio, and there can be no assurance that
these policies will be continued thereafter.
    
 
   
(4) The information in the foregoing table has been restated to reflect an
agreement by Morgan Guaranty Trust Company of New York ("Morgan Guaranty"), an
affiliate of Morgan, to reimburse the trust to the extent certain expenses
exceed in any fiscal year 0.75%, 0.90%, 1.15% of the average daily net assets of
the J.P. Morgan Bond Portfolio, J.P. Morgan Equity Portfolio and J.P. Morgan
Small Company Portfolio, respectively. Without such reimbursements, total fund
annual expenses would have been 1.02% for the J.P. Morgan Bond Portfolio, 1.48%
for the J.P. Morgan Equity Portfolio, 3.43% for the J.P. Morgan Small Company
Portfolio.
    
 
   
(5) Each series has an expense offset arrangement which reduces the series'
custodian fee based upon the amount of cash maintained by the series with its
custodian and dividend disbursing agent, and may enter into other such
arrangements and directed brokerage arrangements (which would also have the
effect of reducing the series' expenses). Any such fee reductions are not
reflected under "Other Expenses".
    
 
   
(6) "Management Fees" include other operating expenses.
    
 
   
(7) The adviser has voluntarily agreed to limit its management fee and to
reimburse each fund's non-management expenses for an indefinite period. Each
fund's Total Annual Expenses will be capped on an annual basis at the percentage
of the fund's average daily net assets shown in the table above. To the extent
that a fund's total expense ratio falls below its limit, the adviser reserves
the right to be reimbursed for management fees waived and fund expenses paid by
it during the prior two fiscal years. The adviser may modify or eliminate this
voluntary expense limit at any time.

                           If you had Account Value allocated to a Sub-Account
                       which invests in one of the first two Funds listed above
                       as of May 1, 1999, you may maintain your existing
                       allocations and may continue to allocate additional net
                       premium payments or make transfers to that Sub-Account.
 
                           If you had Account Value allocated to a Sub-Account
                       which invests in one of the last three Funds listed above
                       as of May 1, 1999, you may maintain your existing
                       allocations, but may not allocate any additional net

                       Sub-Account.
 
                       FEES AND EXPENSES OF THE FUNDS
 
   
                           Fund shares are purchased at net asset value, which
                       reflects the deduction of investment management fees and
                       other expenses. The management fees are charged by each
                       Fund's investment adviser for managing the Fund and
                       selecting its portfolio securities. Other expenses can
                       include such items as interest expense on loans and
                       contracts with transfer agents, custodians, and other
                       companies that provide services to the Fund, and actual
                       expenses may vary.
    
 
   
                           Because they are assessed at the fund level, you will
                       indirectly bear the fees and expenses of the Funds you
                       select. The table contained in the front part of this
                       prospectus shows the fees and expenses paid by the Funds
                       as a percentage of average net assets. These fees and
                       expenses are more fully described in the Fund
                       Prospectuses which accompany this prospectus.
    
 
                       POTENTIAL CONFLICTS
 
                           We, as well as other affiliated and unaffiliated
                       insurance companies, may also purchase shares of the
                       Funds on behalf of other separate accounts used to fund
                       variable benefits payable under other variable life
                       insurance and variable annuity contracts. As a result, it
                       is possible, though we do not anticipate, that a material
                       conflict may arise between the interests of our
                       policyowners with respect to the Variable Account and
                       those of other variable contractowners with respect to
                       the other separate accounts that participate in the
                       Funds. The Funds have agreed to monitor themselves for
                       the existence of any material conflict between the
                       interests of variable contractowners. In the event of
                       such a conflict involving a Fund, we will take any steps
                       necessary to remedy the conflict including withdrawing
                       the assets of the Variable Account from the Fund. If the
                       Variable Account or another separate account withdraws
                       its assets from a Fund for

                       this reason, the Fund may be forced to sell its portfolio
                       securities at disadvantageous prices which would
                       negatively affect the investment performance of the
                       corresponding Sub-Account.
 
                                         ABOUT THE POLICY
 
                           This prospectus describes the standard features of
                       the Policy. Your Policy, as issued, may differ in some
                       respects due to legal requirements of the state where
                       your Policy is issued.
 
                       APPLICATION AND ISSUANCE
 
                           To apply for a Policy, you must submit an application
                       to our Principal Office. We will then follow underwriting
                       procedures designed to determine the insurability of the
                       proposed insured. We offer the Policy on a regular (or
                       medical) underwriting, simplified underwriting, or
                       guaranteed issue basis. The proposed insured generally
                       must be less than 81 years old for a Policy to be issued
                       on a medical underwriting basis, less than 76 years old
                       for issuance on a simplified underwriting basis, and less
                       than 71 years old for issuance on a guaranteed issue
                       basis. For Policies underwritten on a medical or
                       simplified basis, we may require that the proposed
                       insured undergo one or more medical examinations and that
                       you provide us with such additional information as we may
                       deem necessary, before an application is approved. We
                       will issue Policies on a guaranteed basis with respect to
                       certain groups of insureds. Policies issued on a
                       guaranteed basis must be pre-approved based on
                       information you provide to us on a master application and
                       on certain other underwriting requirements which all
                       members of a proposed group of insureds must meet.
                       Proposed insureds must be acceptable risks based on our
                       underwriting limits and standards. We will not issue a
                       Policy until the underwriting process has been completed
                       to our satisfaction. In addition, we reserve the right to
                       reject any application that does not meet our
                       underwriting requirements or to "rate" an insured as a
                       substandard risk, which will result in increased Monthly
                       Cost of Insurance charges.

 There are two                 DEATH BENEFIT COMPLIANCE TEST.  Your Policy
 tax-law compliance    must, at all times, satisfy one of two legal standards
 tests. You select     for it to qualify as life insurance and thus be entitled
 which applies to      to receive favorable tax treatment under applicable
 your Policy.          federal tax law. We will refer to these standards as the
                       "Cash Value Accumulation Test" and the "Guideline
                       Premium Test." Under both tests, the Death Benefit must
                       effectively always equal or exceed your Account Value
                       multiplied by a certain percentage (the "Death Benefit
                       Percentage"). The Death Benefit Percentages for the
                       Guideline Premium Test vary by age, whereas those for
                       the Cash Value Accumulation Test vary by age and sex.
                       The Death Benefit Percentages for the Cash Value
                       Accumulation Test, in general, are greater than those
                       for the Guideline Premium Test. The Guideline Premium
                       Test imposes limits on the amount of premium you may pay
                       under your Policy, whereas the Cash Value Accumulation
                       Test does not.
 
                           You must specify in your policy application which of
                       these tests will apply to your Policy. You may not change
                       your selection once your Policy has been issued. In
                       general, if your primary objective is maximum
                       accumulation of Account Value during the initial Policy
                       Years, then the Cash Value Accumulation Test would be the
                       more appropriate choice. If your primary objective is the
                       most economically efficient method of obtaining a
                       specified amount of coverage, then the Guideline Premium
                       Test is generally more appropriate. Because your choice
                       of tests depends on complex factors and may not be
                       changed, you should consult with a qualified tax adviser
                       before deciding.
    
 
                           INITIAL PREMIUM PAYMENT.  A Minimum Premium, as
                       specified in your Policy, will be due and payable as of
                       the Issue Date. The Minimum Premium will vary based on
                       the insured's Class, Issue Age, and sex and on the amount
                       of insurance coverage. Pending approval of your
                       application, we will allocate any premium payments you
                       make to our General Account. If your application is not
                       approved, we will promptly return your premium payments.
 
   
                           EFFECTIVE DATE OF COVERAGE.  Upon approval of your
                       application, we will issue to you a Policy on the life of
                       the insured which will set forth your rights and our
                       obligations. The Effective Date of Coverage for the
                       Policy will be the latest of--
    
 
 The ISSUE DATE is             -  the ISSUE DATE,
 the date specified        - the date we approve the application for your

                           INSURABLE INTEREST REQUIREMENT.  You must have an
                       insurable interest in the life of the insured up to the
                       full amount of insurance coverage. Otherwise, your Policy
                       will not qualify as life insurance under applicable state
                       insurance and federal tax law. You should consult with a
                       qualified adviser when determining the amount of coverage
                       and before taking any action to increase the amount of
                       existing coverage to ensure that you have an insurable
                       interest for the full amount of coverage.
 
                       FREE LOOK PERIOD
 
   
                           If you are not satisfied with your Policy, you may
                       return it by delivering or mailing it to Our Principal
                       Office or to the sales representative through whom you
                       purchased the Policy within 20 days from the date of
                       receipt (unless a different period is applicable under
                       state law) or within 45 days after your application is
                       signed, whichever period ends later (the "Free Look
                       Period").
    
 
                           If you return your Policy during the Free Look
                       Period, your Policy will be deemed void and you will
                       receive a refund equal to the sum of--
 
                           -   the difference between any premium
                               payments made, including fees and
                               charges, and the amounts allocated to
                               the Variable Account;
 
                           -   the value of the amounts allocated to
                               the Variable Account on the date the
                               cancellation request is received by us
                               or the sales representative through
                               whom you purchased the Policy, and
 
                           -   any fees or charges imposed on amounts
                               allocated to the Variable Account.
 
                           If required by applicable state insurance law,
                       however, you will receive instead a refund equal to the
                       sum of all premium payments made, without regard to the
                       investment experience of the Variable Account. Unless you
                       are entitled to receive a full refund of premium, you
                       bear all of the investment risks with respect to the
                       amount of any net premiums allocated to the Variable
                       Account during the Free Look Period with respect to your
                       Policy.
 
   
                           If you are entitled under applicable state law to
                       receive a full refund during the Free Look Period, we
                       will allocate net premium payments to the MFS/Sun Life
                       Series Trust Money Market Series Sub-Account during that
                       period beginning on the Investment Start Date. Upon
                       expiration of the Free-Look Period, we will reallocate
                       your Account Value and allocate future net premium
                       payments in accordance with your instructions.

                       PREMIUM PAYMENTS
 
 The frequency and             In general, you may choose the frequency and
 amount of your        amount of any additional premium payments subject to the
 premium payments may  limits described below. You will be required, however,
 have tax              to make an initial minimum premium payment, as described
 consequences.         above. All premium payments should be made payable to
                       "Sun Life Assurance Company of Canada (U.S.)" and mailed
                       to our Principal Office.
 
                           GENERAL LIMITATIONS.  We reserve the right to limit
                       the number of premium payments we accept on an annual
                       basis. No premium payment may be less than $100 without
                       our consent, although we will accept a smaller premium
                       payment if it is necessary to keep your Policy in force.
                       We reserve the right not to accept a premium payment that
                       causes the Death Benefit to increase by an amount that
                       exceeds the premium received and we may require
                       satisfactory evidence of insurability before we accept
                       such a premium.
 
                           GUIDELINE PREMIUM TEST LIMITATIONS.  The Guideline
                       Premium Test limits the amount of premium you may pay per
                       year. We will not accept premium payments that would, in
                       our opinion, exceed these limits, if you have chosen this
                       test as the applicable Death Benefit Compliance Test. If
                       you make a premium payment in excess of these limits, we
                       will accept only that portion of the premium within those
                       limits and refund the remainder to you. We will inform
                       you of the applicable maximum premium limitations for the
                       coming years in our annual report to you. In contrast,
                       the Cash Value Accumulation Test does not impose any
                       additional limitations on the amount of premium you may
                       pay.
 
                           PLANNED PERIODIC PREMIUMS.  While you are not
                       required to make premium payments according to a fixed
                       schedule, you may select a planned periodic premium
                       schedule and corresponding billing period, subject to our
                       premium limits. In general, the billing period must be
                       annual or semiannual. We will send reminder notices for
                       the planned periodic premium at the beginning of each
                       billing period unless reminder notices have been
                       suspended as described below. You are not required,
                       however, to pay the planned periodic premium; you may
                       increase or decrease premium payments, subject to our
                       limits, and you may skip a planned payment or make

                       schedule or the billing period, subject to our approval.
                       Depending on the investment performance of the
                       Sub-Accounts you select, the planned periodic premium may
                       not be sufficient to keep your Policy in force, and you
                       may need to change your planned payment schedule or make
                       additional payments in order to prevent termination of
                       your Policy. We reserve the right to suspend reminder
                       notices if premiums are not being paid (except for
                       notices in connection with the grace period). We will
                       notify you prior to suspending reminder notices. We will
                       also suspend reminder notices at your written request.

                       percentages must be in whole numbers.
 
                           You may change the allocation of future Net Premium
                       at any time by telephoning or writing to our Service

                       have a properly completed telephone authorization form
                       for you on file. We, our affiliates and the
                       representative from whom you purchased your Policy will
                       not be responsible for losses resulting from acting upon
                       telephone requests reasonably believed to be genuine. We
                       will use reasonable procedures to confirm that
                       instructions communicated by telephone are genuine. You
                       will be required, for example, to identify yourself by
                       name and a personal identification number. In addition,
                       telephone requests may be recorded. An allocation change
                       will be effective as of the date our Service Center
                       receives your request for that change.
 
                           MODIFIED ENDOWMENT CONTRACTS.  Less favorable federal
                       tax rules apply to life insurance policies that are
                       defined as "Modified Endowment Contracts." One way your
                       Policy could become a Modified Endowment Contract is if
                       you pay premiums in excess of applicable tax-law
                       limitations.
 
                           We will notify you if we receive a premium that
                       would, in our opinion, cause your Policy to become a
                       Modified Endowment Contract. We will not credit the
                       premium unless we receive specific instructions from you
                       to do so. If we have not received instructions within 24
                       hours of the date we sent notice to you, we will
                       immediately return the premium.
 
                       ADDITIONAL PROTECTION BENEFIT RIDER (APB RIDER)
 
                           The Policy may be issued with an APB Rider. This
                       rider provides life insurance coverage, annually
                       renewable to Attained Age 100, on the life of the insured
                       equal to the amount of the APB Rider Death Benefit. You
                       will be required to specify the initial APB Rider Face
                       Amount in your policy application.
 
                           The cost of the APB Rider will be included in the
                       Monthly Cost of Insurance deduction. The applicable
                       guaranteed maximum Monthly Cost of Insurance Rates for
                       the APB Rider Death Benefit exceed those for the Base
                       Death Benefit.

                       DEATH BENEFIT
 
                           POLICY PROCEEDS.  If your Policy is in force at the
                       time of the insured's death and we have received Due
                       Proof of the insured's death, we will pay your designated
                       beneficiary an amount equal to--
 
                           -   the amount of the Base Death Benefit,

                               benefits.
 
                           The Amount of the Base Death Benefit depends upon the
                       death benefit option in effect at the time of the
                       insured's death.
 
                           DEATH BENEFIT OPTIONS.  The Policy has two death
                       benefit options. You will be required to select one of
                       them in your policy application.
 
                           OPTION A--SPECIFIED FACE AMOUNT.  Under this option,
                       the Base Death Benefit is THE GREATER OF--

                               applicable Death Benefit Percentage.

                           -   the Specified Face Amount plus the

                           -   the Account Value multiplied by the
                               applicable Death Benefit Percentage.
 
                           Option B is not available, however, and you will be
                       deemed to have elected Option A, if you have chosen the
                       Cash Value Accumulation Test as the applicable Death
                       Benefit Compliance Test.
 
                           At any time the Base Death Benefit is defined as the
                       Account Value multiplied by the applicable Death Benefit
                       Percentage, and the Base Death Benefit minus Account
                       Value exceeds your Policy's Total Face Amount, we reserve
                       the right to distribute Account Value to you as a partial
                       surrender to the extent necessary so that the Base Death
                       Benefit minus Account Value will equal the Total Face
                       Amount. You will not have the option of providing
                       evidence of insurability to maintain a higher level of
                       Base Death Benefit.
 
                           We will notify you in writing if we exercise our
                       right to distribute Account Value to you as a partial
                       surrender as described above. You may allocate the
                       partial surrender among the Sub-Accounts of the Variable
                       Account. If you do not specify the allocation, then we
                       will allocate the partial surrender among the
                       Sub-Accounts in the same proportion that the Account
                       Value of each Sub-Account bears to the aggregate Account
                       Value of all Sub-Accounts on the date of partial
                       surrender.
 
                           CHANGES IN THE DEATH BENEFIT OPTION.  If you have
                       chosen the Guideline Premium Test as the applicable Death
                       Benefit Compliance Test, then you may change the death
                       benefit option, subject to our underwriting rules in
                       effect at the time of the change. Requests for a change
                       must be made in writing to our Service Center. The
                       effective date of the change will be the Policy
                       Anniversary on or next following the date of receipt of
                       your request.
 
                           If you change from Option B to Option A, we will
                       increase the Specified Face Amount by the Account Value.
                       If you change from Option A to Option B, we will reduce
                       the Specified Face Amount by the Account Value. In either
                       case, the amount of the Base Death Benefit at the time of
                       change will not be altered, but the change will affect
                       the determination of the Base Death Benefit going
                       forward.
 
                           A change in the death benefit option could cause
                       total premiums paid prior to the change to exceed the
                       applicable maximum premium limitations under the
                       Guideline Premium Test. The change could also reduce
                       these limitations for future premium payments. If the
                       requested change causes total premiums paid to exceed the
                       applicable maximum premium limitations, you will be
                       required to make a partial surrender of your Policy. You
                       should consult a qualified tax adviser before changing
                       the death benefit option.

                           APB RIDER DEATH BENEFIT.  The APB Rider Death Benefit
                       is THE GREATER OF ZERO OR THE RESULT OF the APB Rider
                       Face Amount minus the excess, if any, of the Base Death
                       Benefit over--
 
                           -   the Specified Face Amount, if the
                               applicable death benefit option is
                               Option A, or
 
                           -   the Specified Face Amount plus the
                               Account Value, if the applicable death
                               benefit option is Option B.
 
                           MINIMUM FACE AMOUNT.  Total Face Amount is the sum of
                       the Specified Face Amount and the APB Rider Face Amount.
                       In general, the Total Face Amount must be at least
                       $50,000, of which the Specified Face Amount must be at
                       least $5,000. We reserve the right to waive these
                       minimums and to offer your Policy only in conjunction
                       with an APB Rider with a specified APB Rider Face Amount.
 
                           CHANGES IN FACE AMOUNT.  After the end of the first
                       Policy Year, you may change the Specified Face Amount
                       and, if applicable, the APB Rider Face Amount, subject to
                       our underwriting rules in effect at the time of the
                       change. Unless you specify otherwise, we will first apply
                       a change to the APB Rider Face Amount to the extent
                       possible. You must send your request for a change to our
                       Service Center in writing. The Effective Date of Coverage
                       for changes will be--
 
                           -   for any increase in coverage, the
                               Monthly Anniversary Day that falls on
                               or next follows the date we approve
                               the supplemental application for the
                               increase; and
 
                           -   for any decrease in coverage, the
                               Monthly Anniversary Day that falls on
                               or next follows the date we receive
                               your request.
 
                           INCREASES IN FACE AMOUNT.  An increase in the
                       Specified Face Amount and, if applicable, the APB Rider
                       Face Amount, is subject to our underwriting rules in
                       effect at the time of the increase. You may be required
                       to submit satisfactory evidence of the insured's
                       insurability.
 
                           DECREASES IN FACE AMOUNT.  The Specified Face Amount
                       may not decrease to less than the Minimum Specified Face
                       Amount specified in your Policy. Similarly, a decrease in
                       Specified Face Amount or APB Rider Face Amount may not
                       decrease the Total Face Amount to an amount less than the
                       Minimum Total Face Amount specified in your Policy. A
                       decrease in face amount will be applied--
 
                           -   first, to the most recent increase;
 
                           -   second, to the next most recent

                           -   finally, to the initial face amount.
 
                           A decrease in the Specified Face Amount or APB Rider
                       Face Amount could cause total premiums paid prior to the
                       change to exceed the applicable maximum premium
                       limitations under the Guideline Premium Test. The change
                       could also reduce these limitations for future premium
                       payments. If the requested change causes total premiums
                       paid to exceed the applicable maximum premium
                       limitations, you will be required to make a partial
                       surrender of your Policy. You should consult a qualified
                       tax adviser before decreasing the Specified Face Amount
                       or APB Rider Face Amount.
 
                       ACCOUNT VALUE
 
                           Your Account Value is the sum of the amounts in each
                       Sub-Account of the Variable Account with respect to your
                       Policy, plus the amount of the Loan Account.

                       loan is made. You may allocate the policy loan among the
                       Sub- Accounts. If you do not specify the allocation,
                       then we will allocate the policy loan among the
                       Sub-Accounts in the same proportion that the Account
                       Value of each Sub-Account bears to the aggregate Account
                       Value of all Sub-Accounts immediately prior to the loan.
 
                           Interest on the policy loan will accrue daily at an
                       annual rate of 5% in Policy Years one through ten and
                       4.25% thereafter. This interest will be due and payable
                       to us in arrears on each Policy Anniversary. Any unpaid
                       interest will be added to the principal amount as an
                       additional policy loan and will bear interest at the same
                       rate and in the same manner as the prior policy loan.
 
                           All funds we receive from you will be credited to
                       your Policy as premium unless we have received
                       satisfactory written notice that the funds are to be
                       applied to repay a policy loan. It is generally
                       advantageous to repay a loan rather than to make a
                       premium payment, because premium payments incur expense
                       charges but loan repayments do not. Loan repayments will
                       first reduce the outstanding balance of the policy loan
                       and then accrued but unpaid interest on such loans. We
                       will accept repayment of any policy loan at any time
                       before Maturity. The amount of the loan repayment up to
                       the outstanding balance of the policy loan will be
                       transferred from the Loan Account to the Sub-Accounts.
                       You may allocate the loan repayment among the
                       Sub-Accounts. If you do not specify the allocation, then
                       we will allocate the loan repayment among the Sub-
                       Accounts in the same proportion that the Account Value of
                       each Sub-Account bears to the total Account Value minus
                       the Loan Account immediately prior to the loan repayment.
 
                           DEFERRAL OF PAYMENT.  We will usually pay any amount
                       due from the Variable Account within seven days after the
                       Valuation Date following our receipt of written notice
                       for payment or, in the case of death of the insured, Due
                       Proof of such death. Payment of any amount payable from
                       the Variable

                       Account on death, surrender, partial surrender, or policy
                       loan may be postponed whenever--
 
                           -   the New York Stock Exchange is closed,
                               other than customary weekend and
                               holiday closing, or trading on that
                               exchange is otherwise restricted;
 
                           -   the SEC, by order, permits
                               postponement for the protection of
                               policyowners; or
 
                           -   an emergency exists as determined by
                               the SEC, as a result of which disposal
                               of securities is not reasonably
                               practicable, or it is not reasonably
                               practicable to determine the value of
                               the assets of the Variable Account.
 
                       CASH SURRENDER VALUE PAYABLE UPON MATURITY
 
                           If the insured is living and your Policy is in force
                       on the date of Maturity, the Cash Surrender Value is
                       payable to you.
 
                       CHARGES, DEDUCTIONS AND REFUNDS
 
                           EXPENSE CHARGES APPLIED TO PREMIUM.  We deduct
                       charges from each premium payment for premium taxes and
                       our federal tax obligations and as a sales load.
 
                           States and a few cities and municipalities may impose
                       taxes on premiums paid for life insurance, which
                       generally range from 2% to 4% of premium but may exceed
                       4% in some states (for example, Kentucky). We will from
                       time to time determine the applicable premium tax rate
                       based on the rate we expect to pay in your state of
                       residence. The premium tax rate is guaranteed not to
                       exceed 4% for all states except Kentucky, in which case
                       it is guaranteed not to exceed 9%. If you change your
                       state of residence, we will adjust the premium tax rate
                       to reflect the rate for the new state of residence.
 
                           We deduct a 1.25% charge from each premium payment
                       for our federal tax obligations. This charge is
                       guaranteed not to exceed 1.25%.
 
 TARGET PREMIUM                We also charge a 8.75% sales load on each
 varies based on the   premium payment up to an amount of Target Premium
 Specified Face        specified in your Policy and a 2.25% sales load on
 Amount and the        premiums paid in excess of TARGET PREMIUM for each of
 insured's Issue Age   the first seven Policy Years. Sales load rates are
 and sex.              guaranteed not to exceed these amounts. There are no
                       sales load charges after the seventh Policy Year. We may
                       reduce or waive the sales load for certain group or
                       sponsored arrangements and corporate purchasers.

<PAGE>
                           SALES LOAD REFUND AT SURRENDER.  If you surrender
                       your Policy during the first three Policy Years, we will
                       refund a portion of the sales load charged against
                       premium payments MADE DURING THE POLICY YEAR IN WHICH YOU
                       SURRENDERED YOUR POLICY. We will refund an amount equal
                       to 6% of premium paid up to the Target Premium, plus the
                       entire amount of any sales load charged against premium
                       paid in excess of the Target Premium.
 
                           MORTALITY AND EXPENSE RISK CHARGE.  We deduct a daily
                       charge from the assets of the Variable Account for the
                       mortality and expense risks we assume with respect to the
                       Policy. This charge is based on the applicable Daily Risk
                       Percentage, which we will from time to time determine
                       based on our expectations of future interest, mortality
                       experience, persistency, expenses and taxes. Expressed as
                       an equivalent annual rate, the Daily Risk Percentage is
                       guaranteed not to exceed 0.90% (0.0024548% daily) of
                       assets. Our current effective annual rates as a
                       percentage of assets are--
 
                           -   0.60% (0.0016389% daily) for Policy
                               Years 1 through 10;
 
                           -   0.20% (0.0005474% daily) for Policy
                               Years 11 through 20; and
 
                           -   0.10% (0.0002738% daily) thereafter.
 
                           The mortality risk we assume is that the group of
                       lives insured under the Policies may, on average, live
                       for shorter periods of time than we estimated. The
                       expense risk we assume is that the costs of issuing and
                       administering Policies may be more than we estimated.
 
                           MONTHLY EXPENSE CHARGE.  We deduct a flat charge at
                       the beginning of each month to cover administrative and
                       other expenses actually incurred. We will from time to
                       time determine the applicable Monthly Expense Charge
                       based on our expectations of future expenses, which will
                       not exceed $13.75 in any Policy Month. We will allocate
                       the Monthly Expense Charge among the Sub-Accounts in the
                       same proportion that the Account Value of each
                       Sub-Account bears to the aggregate Account Value of all
                       Sub-Accounts immediately prior to the deduction.
                       Currently, the Monthly Expense Charge is $13.75 per month
                       for the first Policy Year and $7.50 per month thereafter.
 
                           MONTHLY COST OF INSURANCE.  We deduct a Monthly Cost
                       of Insurance charge from your Account Value to cover
                       anticipated costs of providing insurance coverage. This
                       charge is made, in arrears, at the end of each Policy
                       Month. If you surrender your Policy on any day other than
                       a Monthly Anniversary Day, we will deduct a cost of
                       insurance charge on a pro-rata basis. We will allocate
                       the Monthly Cost of Insurance deduction among
                       Sub-Accounts in the same

<PAGE>
                       proportion that the Account Value of each Sub-Account
                       bears to the aggregate Account Value of all Sub-Accounts
                       immediately prior to the deduction.
 
                           Monthly cost of insurance rates are based on the
                       length of time the Policy has been in force and on the
                       insured's sex (except for unisex Policies), Issue Age,
                       Class and table rating, if any. We will from time to time
                       determine the applicable rates based on our expectations
                       of future experience with respect to mortality,
                       persistency, interest rates, expenses and taxes. Our cost
                       of insurance rates for coverage under the Policy are
                       guaranteed not to exceed the applicable maximum monthly
                       rates shown in your Policy which are based on the 1980
                       Commissioner's Standard Ordinary Mortality Table A (for
                       males and unisex Policies) or Table G (for females),
                       unless the insured has been rated a substandard risk. Our
                       cost of insurance rates for coverage under the APB Rider
                       are guaranteed not to exceed the applicable maximum
                       monthly rates shown in your Policy. In general, the
                       maximum monthly rates for coverage under the APB Rider
                       will not exceed 125% of the monthly rates based on the
                       1980 CSO Mortality Table A (for males and unisex
                       Policies) or G (for females), unless the insured has been
                       rated a substandard risk. Monthly cost of insurance rates
                       for classes of insureds with substandard risk ratings are
                       based on multiples of the CSO Mortality Tables described
                       above.
 
                           REDUCTION OF CHARGES.  We reserve the right to reduce
                       any of our charges and deductions in connection with the
                       sale of the Policy if we expect that the sale may result
                       in cost savings, subject to any requirements we may from
                       time to time impose. We may change our requirements based
                       on experience. We will determine the propriety and amount
                       of any reduction. No reduction will be unfairly
                       discriminatory against the interests of any class of
                       policyowner.
 
                       TERMINATION OF POLICY
 
                           Your Policy will terminate on the earliest of--
 
                           -   the date we receive your request to
                               surrender,
 
                           -   the expiration date of the grace
                               period,
 
                           -   the date of insured's death, or
 
                           -   the date of Maturity.
 
                       OTHER POLICY PROVISIONS
 
                           ALTERATION.  Our sales representatives do not have
                       the authority to either alter or modify your Policy or to
                       waive any of its provisions. The only persons

                       with this authority are our president, actuary,
                       secretary, or one of our vice presidents.
 
                           ASSIGNMENTS.  During the lifetime of the insured, you
                       may assign all or some of your rights under the Policy.
                       All assignments must be filed at our Service Center and
                       must be in satisfactory written form. The assignment will
                       then be effective as of the date you signed the form,
                       subject to any action taken before we receive it at our
                       Service Center. We are not responsible for the validity
                       or legal effect of any assignment.
 
                           RIGHTS OF OWNER.  While the insured is alive, unless
                       you have assigned any of these rights, you may--
 
                           -   transfer ownership to a new owner;
 
                           -   name a contingent owner who will
                               automatically become the owner of the
                               Policy if you die before the insured;
 
                           -   change or revoke a contingent owner;
 
                           -   change or revoke a beneficiary; and
 
                           -   exercise all other rights in the
                               Policy.
 
                           When you transfer your rights to a new owner, you
                       automatically revoke any prior contingent owner
                       designation. You do not affect a prior beneficiary when
                       you merely transfer ownership, or change or revoke a
                       contingent owner designation. When you want to change or
                       revoke a prior beneficiary designation, you have to
                       specify that action.
 
                           You do not need the consent of a beneficiary or a
                       contingent owner in order to exercise any of your rights.
                       However, you must give us written notice of the requested
                       action. The request must be filed at our Service Center
                       and must be in satisfactory written form. Your request
                       will then, except as otherwise specified in the Policy,
                       be effective as of the date you signed the form, subject
                       to any action taken before we receive it at our Service
                       Center.
 
                           RIGHTS OF BENEFICIARY.  The beneficiary has no rights
                       in the Policy until the death of the insured. If a
                       beneficiary is alive at that time, the beneficiary will
                       be entitled to payment of the Policy Proceeds as they
                       become due.
 
                           REPORTS TO POLICYOWNERS.  We will send you a report
                       at least once each Policy Year. The report will show
                       current policy values, premiums paid, and deductions made
                       since the last report. It will also show the balance of
                       any outstanding policy loans and accrued interest on
                       those loans.

                           ILLUSTRATIONS.  Upon request, we will provide you
                       with a hypothetical illustration of future Account Value
                       and Death Benefits. This illustration will be furnished
                       to you for a fee not to exceed $25.
 
                           CONVERSION.  You may convert your Policy into a
                       flexible premium universal life policy offered by an
                       affiliate, Sun Life Assurance Company of Canada, during
                       the first 24 months after the Issue Date while the Policy
                       is in force. Choice of a new policy is subject to our
                       approval and will be restricted to those policies that
                       offer the same Class and rating as your Policy. Our
                       affiliate will issue the new policy with the same Class
                       and rating as the Policy without new evidence of the
                       insured's insurability. This provision does not apply to
                       the APB Rider, if any, or to any other supplemental
                       benefits that may be attached to the Policy. Any riders
                       or supplemental benefits will terminate automatically
                       when the Policy is converted.
 
                           MISSTATEMENT OF AGE OR SEX.  If the age or sex
                       (unless a unisex Policy) of the insured is stated
                       incorrectly in your policy application, the amounts
                       payable by us will be adjusted.
 
                           MISSTATEMENT DISCOVERED AT DEATH--The Death Benefit
                       will be recalculated to that which would be purchased by
                       the most recently charged Monthly Cost of Insurance rate
                       for the correct age or sex.
 
                           MISSTATEMENT DISCOVERED PRIOR TO DEATH--The Account
                       Value will be recalculated from the Issue Date using the
                       Monthly Cost of Insurance rates based on the correct age
                       or sex.
 
                           SUICIDE.  Unless state law otherwise requires, if the
                       insured, whether sane or insane, commits suicide within
                       two years after the Issue Date, we will not pay any part
                       of the Policy Proceeds. We will refund to you the
                       premiums paid, minus the amount of any Policy Debt and
                       any partial surrenders.
 
                           INCONTESTABILITY.  All statements made in an
                       application or in a supplemental application are
                       representations and not warranties. We will rely on these
                       statements when approving the issuance, increase in face
                       amount, increase in Base Death Benefit over premium paid,
                       or change in death benefit option of the Policy. We can
                       use no statement in defense of a claim unless the
                       statement was made in the application or in a
                       supplemental application. In the absence of fraud, after
                       a Policy has been in force during the lifetime of the
                       insured for a period of two years from its Issue Date, we
                       cannot contest it except for non-payment of premiums.
                       However, any increase in the Total Face Amount which is
                       effective after the Issue Date will be incontestable only
                       after the increase has been in force during the lifetime
                       of the insured for two years from the effective date of
                       coverage of the increase. Any increase in Base Death

                       premium paid or increase in Base Death Benefit due to a
                       death benefit option change will be incontestable only
                       after such increase has been in force during the lifetime
                       of the insured for two years from the date of the
                       increase.
 
                           ADDITION, DELETION OR SUBSTITUTION OF
                       INVESTMENTS.  Subject to our obtaining any necessary
                       regulatory approvals, shares of other registered open-end
                       investment companies or unit investment trusts may be
                       substituted both for fund shares already purchased by the
                       Variable Account and/or as the security to be purchased
                       in the future. In addition, the investment policies of
                       the Sub-Accounts will not be changed without the approval
                       of the Insurance Commissioner of the State of Delaware.
                       We also reserve the right to eliminate or combine
                       existing Sub-Accounts or to transfer assets between
                       Sub-Accounts. In the event of any substitution or other
                       act described above, we may make appropriate amendment to
                       the Policy to reflect the substitution.
 
                           NONPARTICIPATING.  The Policy does not pay dividends.
                       The Policy does not share in our profits or surplus
                       earnings.
 
                           MODIFICATION.  Upon notice to you, we may modify the
                       Policy if that modification--
 
                           -   is necessary to make the Policy or the
                               Variable Account comply with any law
                               or regulation issued by a governmental
                               agency to which we are or the Variable

                           -   is necessary to assure continued
                               qualification of the Policy under the
                               Internal Revenue Code or other federal
                               or state laws as a life insurance
                               policy;
 
                           -   is necessary to reflect a change in
                               the operation of the Variable Account
                               or the Sub-Accounts; or

                               Sub-Account options.
 
                           We also reserve the right to modify certain
                       provisions of the Policy as stated in those provisions.
                       In the event of any such modification, we may make
                       appropriate amendment to the Policy to reflect the
                       modification.
 
                           ENTIRE CONTRACT.  Your entire contract with us
                       consists of the Policy, including your policy application
                       and any attached copies of supplemental applications for
                       increases in the face amount. Any hypothetical
                       illustrations prepared in connection with the Policy do
                       not form a part of our contract with you and are intended
                       solely to provide information about how policy values may
                       be affected by different investment returns and other
                       factors.

                                     PERFORMANCE INFORMATION
 
 We may present the            From time to time, we may advertise TOTAL RETURN
 performance of the    and AVERAGE ANNUAL TOTAL RETURN of the Funds. This
 underlying fund       performance information is based on historical earnings
 options in sales      and is not intended to indicate future performance.
 literature.
 
                           Total return for a Fund refers to the total of the
                       income generated by the Fund net of total operating
                       expenses plus capital gains and losses, realized or
                       unrealized, for the Fund. Total return for the
                       Sub-Accounts refers to the total of the income generated
                       by the Fund net of total operating expenses plus capital
                       gains and losses, realized or unrealized, for the Fund
                       and net of the mortality and expense risk charge. Average
                       annual total return reflects the hypothetical annually
                       compounded return that would have produced the same
                       cumulative return if the Fund's or Sub-Account's
                       performance had been constant over the entire period.
                       Because average annual total returns tend to smooth out
                       variations in the return of the Fund or Sub-Account, they
                       are not the same as actual year-by-year results.
 
                           We may compare performance information in reports and
                       promotional literature to--

                               so that investors may compare the
                               Sub-Account results with those of a

                               regarded by investors as
                               representative of the securities

                               and assets, or tracked by other

                               who rank such investment products on
                               overall performance or other criteria;

                           We may provide in advertising, sales literature,
                       periodic publications or other materials information on
                       various topics of interest to policyowners and
                       prospective policyowners. Topics may include--
 
                           -   the relationship between sectors of
                               the economy and the economy as a whole
                               and its effect on various securities
                               markets, investment strategies and
                               techniques (such as value investing,

                               transfer and account rebalancing);
 
                           -   the advantages and disadvantages of
                               investing in tax-deferred and taxable
                               investments;
 
                           -   customer profiles and hypothetical
                               purchase and investment scenarios;
 
                           -   financial management and tax and
                               retirement planning; and
 
                           -   investment alternatives to
                               certificates of deposit and other
                               financial instruments, including
                               comparisons between the Policy and the
                               characteristics of and market for such
                               financial instruments.
 
                           The Policy was first offered to the public in 1997.
                       We may, however, advertise total return data based on the
                       period of time that the Funds have been in existence. The
                       results for any period prior to the time the Policy was
                       first publicly offered will be calculated as if the
                       Policy had been offered during that period of time.
 
                                          VOTING RIGHTS
 
                           We will vote shares of the Funds held in the Variable
                       Account in accordance with instructions received from
                       policyowners having a voting interest in the
                       corresponding Sub-Accounts, to the extent required by
                       law. We will provide each policyowner who has a voting
                       interest a Sub-Account with the proxy materials of the
                       corresponding Fund, together with an appropriate form for
                       the policyowner to submit its voting instructions to us.
                       We will vote shares for which we receive no timely
                       instructions, together with shares not attributable to
                       any Policy, in the same proportion as those shares held
                       by the Sub-Account for which we receive instructions.
 
                           We will determine the number of shares for which you
                       are entitled to provide voting instructions as of the
                       record date established for the applicable Fund. This
                       number is determined by dividing your Account Value in
                       the Sub-Account, if any, by the net asset value of one
                       share in the corresponding Fund.

                           We may, if required by state insurance regulators,

                       subclassification or investment objective of one or more
                       of the Funds, or to approve or disapprove an investment
                       advisory contract for a Fund. In addition, we may

                       the investment policies or in any investment adviser or
                       principal underwriter of a Fund. Our disapproval of any
                       such change must be reasonable and, in the case of a
                       change in investment policies or investment adviser,
                       based on a good faith determination that the change would
                       be contrary to state law or otherwise inappropriate in
                       light of the objectives and purposes of the Fund. If we
                       disregard voting instructions, we will include a summary
                       of and the reasons for that action in our next periodic
                       report to policyowners.
 
                           We reserve the right to vote shares held in the

                       applicable law.
 
                                      DISTRIBUTION OF POLICY
 
                           We will offer the Policy only in jurisdictions where
                       the Policy may be lawfully sold. The Policy may be sold
                       only by persons who are licensed insurance agents under
                       applicable state law and who are licensed by the National
                       Associated of Securities Dealers, Inc. (the "NASD") to
                       sell variable insurance contracts as a registered
                       representative of a broker-dealer which has entered into
                       a distribution agreement with us and our general
                       distributor, Clarendon Insurance Agency, Inc., one of our
                       wholly-owned subsidiaries. Clarendon is a registered
                       broker-dealer and member of the NASD. Clarendon's
                       principal business offices are located at One Sun Life

                                    FEDERAL TAX CONSIDERATIONS
 
                           The following is a summary of our understanding of
                       current federal income tax laws and is not intended as
                       tax advice. You should be aware that Congress has the
                       power to enact legislation affecting the tax treatment of
                       life insurance contracts which could be applied
                       retroactively. New judicial or administrative
                       interpretation of federal income tax law may also affect
                       the tax treatment of life insurance contracts. The
                       Internal Revenue Code of 1986, as amended (the "Code"),
                       is not in force in the Commonwealth of Puerto Rico.
                       Accordingly, some references in this summary will not
                       apply to Policies issued in Puerto Rico. Any person
                       contemplating the purchase of a Policy or any transaction
                       involving a Policy should consult a qualified tax
                       adviser. WE DO NOT MAKE ANY REPRESENTATION OR PROVIDE ANY
                       GUARANTEE REGARDING THE FEDERAL, STATE OR LOCAL TAX
                       TREATMENT OF ANY POLICY OR ANY TRANSACTION INVOLVING A
                       POLICY.
 
                       OUR TAX STATUS
 
                           We are taxed as a life insurance company under
                       Subchapter L of the Code. Although we account for the
                       operations of the Variable Account separately from our
                       other operations for purposes of federal income taxation,
                       the Variable Account currently is not separately taxable
                       as a regulated investment company or other taxable
                       entity.
 
                           Taxes we pay, or reserve for, that are attributable
                       to the earnings of the Variable Account could affect the
                       Net Investment Factor, which in turn affects your Account
                       Value. Under existing federal income tax law, however,
                       the income (consisting primarily of interest, dividends
                       and net capital gains) of the Variable Account, to the
                       extent applied to increase reserves under the Policy, is
                       not taxable to us. Similarly, no state or local income
                       taxes are currently attributable to the earnings of the
                       Variable Account. Therefore, we do not take any federal,
                       state or local taxes into account when determining the
                       Net Investment Factor. We may take taxes into account
                       when determining the Net Investment Factor in future
                       years if, due to a change in law, our tax status or
                       otherwise, such taxes are attributable to the earnings of
                       the Variable Account.
 
                       TAXATION OF POLICY PROCEEDS
 
                           Section 7702 of the Code provides certain tests for
                       whether a policy will be treated as a "life insurance
                       contract" for tax purposes. Provided that the owner of a
                       Policy has an insurable interest in the insured, we
                       believe that the Policy meets these tests, and thus
                       should receive the same federal income tax treatment as a
                       fixed life insurance contract. As such, the death benefit
                       under the Policy will be eligible for exclusion from the
                       gross income of the beneficiary under Section 101 of the
                       Code, and the owner will not be deemed to be in

                       constructive receipt of the increases in Cash Surrender
                       Values, including additions attributable to interest,
                       dividends, appreciation or gains realized upon transfers
                       among the Sub-Accounts, until actual receipt thereof.
                       CORPORATE OWNERS, HOWEVER, MAY BE SUBJECT TO ALTERNATIVE
                       MINIMUM TAX ON THE ANNUAL INCREASES IN CASH SURRENDER
                       VALUES AND ON THE DEATH BENEFIT.
 
                           To qualify as a life insurance contract under Section
                       7702, the Policy must satisfy certain actuarial
                       requirements. Section 7702 requires that actuarial
                       calculations be based on mortality charges that meet the
                       "reasonable mortality charge" requirements set forth in
                       the Code, and other charges reasonably expected to be
                       actually paid. The law relating to reasonableness
                       standards for mortality and other charges is based on
                       statutory language and certain IRS pronouncements that do
                       not address all relevant issues. Accordingly, although we
                       believe that the mortality and other charges that are
                       used in the calculations (including those used with
                       respect to Policies issued to so-called "sub-standard
                       risks") meet the applicable requirements, we cannot be
                       certain. It is possible that future regulations will
                       contain standards that would require us to modify the
                       mortality and other charges used in the calculations, and
                       we reserve the right to make any such modifications.
 
                           For a variable contract like the Policy to qualify as
                       life insurance for federal income tax purposes, it also
                       must comply with the investment diversification rules
                       found in Section 817 of the Code. We believe that the
                       Variable Account complies with the diversification
                       requirements prescribed by Section 1.817-5 of the
                       Treasury Regulations. We also believe that the owner does
                       not have excessive control over the assets underlying the
                       Policy that would cause the owner to be treated as owning
                       the investments underlying the Policy for federal income
                       tax purposes. If guidelines are adopted which would treat
                       the owner as having excessive control over the
                       investments underlying the Policy, we will take any
                       action (including modification of the Policy or the
                       Variable Account) necessary to comply with the
                       guidelines.
 
                           Upon the complete surrender or lapse of a Policy, the
                       amount by which the sum of the Policy's Cash Surrender
                       Value and any unpaid Policy Debt exceeds the owner's
                       "Investment in the Policy" (as defined below) is treated
                       as ordinary income subject to tax. Any loss incurred upon
                       surrender generally is not deductible.
 
                           The term "Investment in the Policy" means--
 
                           -   the aggregate amount of any premiums
                               or other consideration paid for a
                               Policy, MINUS
 
                           -   the aggregate amount received under a
                               Policy which is excluded from the
                               owner's gross income (other than loan
                               amounts), PLUS

                           -   the amount of any loan from, or
                               secured by, a Policy that is a
                               Modified Endowment Contract (as
                               defined below) to the extent that such
                               amount is included in the owner's
                               gross income.
 
                           The repayment of a policy loan (or the payment of
                       interest on a loan) does not affect the Investment in the
                       Policy.
 
                           The tax consequences of distributions from, and loans
                       taken from or secured by, a Policy depend on whether the
                       Policy is classified as a Modified Endowment Contract
                       under Section 7702A of the Code. Due to the flexibility
                       of the payment of premiums and other rights you have
                       under the Policy, classification of the Policy as a
                       Modified Endowment Contract will depend upon the
                       individual operation of each Policy. A Policy is a
                       Modified Endowment Contract if the aggregate amount paid
                       under the Policy at any time during the first seven
                       Policy Years exceeds the sum of the net level premiums
                       that would have been paid on or before such time if the
                       Policy provided for paid up future benefits after the
                       payment of seven level annual premiums. If there is a
                       reduction in benefits during the first seven Policy
                       Years, the foregoing computation is made as if the Policy
                       originally had been issued at the reduced benefit level.
                       If there is a "material change" to the Policy, the seven
                       year testing period for Modified Endowment Contract
                       status is restarted. A life insurance contract received
                       in exchange for a Modified Endowment Contract also will
                       be treated as a Modified Endowment Contract.
 
                           We have undertaken measures to prevent payment of a
                       premium from inadvertently causing the Policy to become a
                       Modified Endowment Contract. In general, you should
                       consult a qualified tax adviser before undertaking any
                       transaction involving your Policy to determine whether
                       such a transaction would cause the Policy to become a
                       Modified Endowment Contract.
 
                           If a Policy is not a Modified Endowment Contract,
                       cash distributions from the Policy are treated first as a
                       nontaxable return of the owner's Investment in the Policy
                       and then as a distribution of the income earned under the
                       Policy, which is subject to tax. (An exception to this
                       general rule occurs when a cash distribution is made in
                       connection with certain reductions in the death benefit
                       under the Policy in the first fifteen contract years.
                       Such a cash distribution is taxed in whole or in part as
                       ordinary income.) Loans from, or secured by, a Policy
                       that is not a Modified Endowment Contract generally are
                       treated as bona fide indebtedness, and thus are not
                       included in the owner's gross income.
 
                           If a Policy is a Modified Endowment Contract,
                       distributions from the Policy are treated as ordinary
                       income subject to tax up to the amount equal to the
                       excess of the Account Value (which includes unpaid policy
                       loans) immediately

                       before the distribution over the Investment in the
                       Policy. Loans taken from, or secured by, such a Policy,
                       as well as due but unpaid interest thereon, are taxed in
                       the same manner as distributions from the Policy. A 10
                       percent additional tax is imposed on the portion of any
                       distribution from, or loan taken from or secured by, a
                       Modified Endowment Contract that is included in income
                       except when the distribution or loan is made on or after
                       the owner attains age 59 1/2, is attributable to the
                       owner's becoming disabled, or is part of a series of
                       substantially equal periodic payments for the life (or
                       life expectancy) of the owner or the joint lives (or
                       joint life expectancies) of the owner and the owner's
                       Beneficiary. These exceptions are not likely to apply
                       where the Policy is not owned by an individual (or held
                       in trust for an individual). For purposes of the
                       computations described in this paragraph, all Modified
                       Endowment Contracts issued by us (or our affiliates) to
                       the same owner during any calendar year are treated as
                       one Modified Endowment Contract.
 
                           There are limits on the deductibility of policy loan
                       interest. You should consult a qualified tax adviser
                       regarding such deductions.
 
                           An owner generally will not recognize gain upon the
                       exchange of the Policy for another life insurance policy
                       issued by us or another insurance company, except to the
                       extent that the owner receives cash in the exchange or is
                       relieved of policy indebtedness as a result of the
                       exchange. In no event will the gain recognized exceed the
                       amount by which the Policy's Account Value (which
                       includes unpaid policy loans) exceeds the owner's
                       Investment in the Policy.
 
                           A transfer of the Policy, a change in the owner, a
                       change in the beneficiary, certain other changes to the
                       Policy and particular uses of the Policy (including use
                       in a so called "split-dollar" arrangement) may have tax
                       consequences depending upon the particular circumstances
                       and should not be undertaken prior to consulting with a
                       qualified tax adviser. For instance, if you transfer your
                       Policy or designate a new owner in return for valuable
                       consideration (or, in some cases, if the transferor is
                       relieved of a liability as a result of the transfer),
                       then the death benefit payable upon the death of the
                       insured may in certain circumstances be includible in
                       your taxable income to the extent that the death benefit
                       exceeds the prior consideration paid for the transfer and
                       any premiums and other amounts paid later by the
                       transferee. Further, in such a case, if the consideration
                       received exceeds your Investment in the Policy, the
                       difference will be taxed to you as ordinary income.
 
                           Federal, as well as state and local, estate,
                       inheritance and other tax consequences of ownership or
                       receipt of Policy Proceeds will depend on your individual
                       circumstances and those of the beneficiary.

                       YEAR 2000 COMPLIANCE
 
                           During the fourth quarter of 1996, we began a
                       comprehensive analysis of our information technology
                       ("IT") and non-IT systems, including our hardware,
                       software, data, data feed products, and internal and
                       external supporting services, to address the ability of
                       these systems to process date calculations through the
                       year 2000 and beyond correctly. We created a full-time
                       year 2000 project team in early 1997 to manage this
                       endeavor on a company-wide basis. Our year 2000 project
                       is periodically reviewed by internal and external
                       auditors.
 
                           To date, relevant systems have been identified and
                       their components inventoried, needed resolutions have
                       been documented, timelines and project plans have been
                       developed, remediation and testing are in process, and
                       over 70% of

<PAGE>
                       our applications have been certified as compliant.
                       Testing of vendor upgrades not available until late 1998
                       is ongoing, as is re-testing of interfaces to systems
                       certified as compliant and re-testing of mission critical
                       functions.
 
                           In mid-1997, the project team contacted all key
                       vendors to obtain either their certification for the
                       products and services provided or their plan to make
                       those products and services compliant. To date,
                       approximately 90% of these vendors have responded, and
                       the project team is in the process of reviewing their
                       responses. In addition, the project team recently has
                       opened communications with critical business partners,
                       such as third-party administrators, investment property
                       managers, investment mortgage correspondents and others,
                       with the goal that these partners will continue to be
                       able to support our objective of assuring year 2000
                       compliance.
 
                           Although we expect all critical systems to be year
                       2000 compliant before the end of 1999, there can be no
                       assurance that this result will be completely achieved.
                       Factors giving rise to this uncertainty include possible
                       loss of technical resources to perform the work, failure
                       to identify all susceptible systems, non-compliance by
                       third-parties whose systems and operations affect our
                       company, and other similar uncertainties. A possible
                       worst-case scenario might include one or more of our
                       significant systems being non-compliant. Such a scenario
                       could result in material disruption to our operations.
                       Consequences of such disruptions could include, among
                       other possibilities, the inability to update customers'
                       accounts; process payment and other financial
                       transactions; and report accurate data to management,
                       customers, regulators and others. Consequences could also
                       include business interruptions or shutdowns, reputational
                       harm, increased scrutiny by regulators, and litigation
                       related to year 2000 issues. Such potential consequences,
                       depending on their nature and duration, could have
                       material impact on our results of operations and
                       financial position.
 
                           In order to mitigate the risks to our company of
                       material adverse operational or financial impacts from
                       failure to achieve planned year 2000 compliance, we have
                       established contingency planning at the business unit and
                       corporate levels. By year-end 1998, we had expended,
                       cumulatively, approximately $7 million on our year 2000
                       effort, and we expect to incur a further $4.8 million on
                       this effort in 1999.
 
                       FINANCIAL STATEMENTS
 
                           Our financial statements, which are included in this
                       prospectus, should be considered only as bearing on our
                       ability to meet our obligations with respect to the death
                       benefit and our assumption of the mortality and expense
                       risks. They should not be considered as bearing on the
                       investment performance of the shares of any Fund held in
                       the Variable Account.

SUN LIFE OF CANADA (U.S.) VARIABLE ACCOUNT G
 
NOTES TO FINANCIAL STATEMENTS
 
(1) ORGANIZATION
 
Sun Life of Canada (U.S.) Variable Account G (the "Variable Account"), a
separate account of Sun Life Assurance Company of Canada (U.S.), the Sponsor,
was established on July 25, 1996 as a funding vehicle for the variable portion
of certain individual variable life insurance contracts. The Variable Account is
registered with the Securities and Exchange Commission under the Investment
Company Act of 1940 as a unit investment trust.
 
The assets of the Variable Account are divided into Sub-Accounts. Each
Sub-Account is invested in shares of a single corresponding investment portfolio
of one of the following mutual funds: MFS/Sun Life Series Trust, Fidelity
Variable Insurance Products Fund, Fidelity Variable Insurance Products Fund II,
Neuberger & Berman Advisers Management Trust, J.P. Morgan Series Trust II,
Dreyfus Variable Investment Fund, T. Rowe Price Equity Series, Inc. and
Templeton Variable Products Series Fund.
 
(2) SIGNIFICANT ACCOUNTING POLICIES
GENERAL
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
INVESTMENT VALUATIONS
 
Investments in shares of an investment portfolio of the mutual funds are
recorded at their net asset value. Realized gains and losses on sales of shares
are determined on the identified cost basis. Dividend income and capital gain
distributions received by the Sub-Accounts are reinvested in additional shares
and are recognized on the ex-dividend date.
 
Exchanges between Sub-Accounts requested by contract owners are recorded in the
new Sub-Account upon receipt of the redemption proceeds.
 
FEDERAL INCOME TAX STATUS
 
The operations of the Variable Account are part of the operations of the Sponsor
and are not taxed separately. The Variable Account is not taxed as a regulated
investment company. The Sponsor qualifies for the federal income tax treatment
granted to life insurance companies under Subchapter L of the internal Revenue
Code. Under existing federal income tax law, investment income and capital gains
earned by the Variable Account on contract owner reserves are not taxable, and
therefore, no provision has been made for federal income taxes.
 
(3) CONTRACT CHARGES
 
The Sponsor deducts expense charges applied to premium consisting of the premium
tax, the federal DAC tax and the sales load. The premium tax varies by state but
in general will range from 2% to 4% of premium in most states (Kentucky charges
7%). The DAC tax charge is 1.25% of premium. The sales load is 8.75% of premium
up to target premium and 2.25% of premium in excess of target premium. A portion
of the sales load is refunded for surrenders in the first three policy years.
 
The Sponsor deducts certain charges from the account value of each contract,
through the cancellation of units, on a monthly basis. A monthly expense charge
of $13.75 per policy at the beginning of each month

NOTES TO FINANCIAL STATEMENTSCONTINUED
during the first policy year and $7.50 for months thereafter is deducted to
recover certain administration expenses. The Sponsor also deducts a charge at
the end of each policy month for providing life insurance protection. This
charge will be based upon the Sponsor's expectations of future mortality,
persistency, interest rates, expenses and taxes. However, the maximum rates for
the base death benefit for insureds that are not rated substandard risks will
not exceed those based on the 1980 CSO Mortality Tables, and the maximum rates
for the APB rider death benefit for similar insureds will not exceed those based
on 125% of the 1980 CSO Mortality Tables.
 
The Sponsor deducts certain charges from the account value of each contract,
through the cancellation of units, at the end of each valuation period for the
mortality and expense risks assumed by the Sponsor. Through October of 1998, the
daily deduction was .0020471% (which is equivalent to an annual rate of .75%)
for policies in their first ten policy years and .0009572% (which is equivalent
to an annual rate of .35%) for policies in policy year eleven and beyond. The
daily deduction is currently .0016389% (which is equivalent to an annual rate of
 .60%) for policies in their first ten policy years, .0005474% (which is
equivalent to an annual rate of .20%) for the next ten policy years and
 .0002738% (which is equivalent to an annual rate of .10%) for policies in policy
years twenty-one and beyond.

INDEPENDENT AUDITORS' REPORT
 
To the Contract Owners participating in Sun Life of Canada (U.S.) Variable
Account G and the Board of Directors of Sun Life Assurance Company of Canada
(U.S.):
 
We have audited the accompanying statement of condition of Capital Appreciation
Sub-Account, Emerging Growth Sub-Account, Government Securities Sub-Account,
Total Return Sub-Account, World Growth Sub-Account, Equity Income Sub-Account,
Growth Sub-Account, High Income Sub-Account, Money Market Sub-Account,
Contrafund Sub-Account, Index 500 Sub-Account, Limited Maturity Bond
Sub-Account, Partners Sub-Account, Bond Sub-Account, Equity Sub-Account, Small
Company Sub-Account, and Templeton Stock Fund Sub-Account of Sun Life of Canada
(U.S.) Variable Account G (the "Sub-Accounts") as of December 31, 1998, the
related statement of operations for the year then ended and the statements of
changes in net assets for the years ended December 31, 1998 and 1997. These
financial statements are the responsibility of management. Our responsibility is
to express an opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities held at December 31, 1998 by correspondence with the
custodian. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Sub-Accounts at December 31, 1998, the
results of their operations and the changes in their net assets for the
respective stated periods in conformity with generally accepted accounting
principles.

NOTES TO STATUTORY FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996
 
1.  DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
GENERAL
 
Sun Life Assurance Company of Canada (U.S.) (the "Company") is incorporated as a
life insurance company and is currently engaged in the sale of individual
variable life insurance, individual fixed and variable annuities, group fixed
and variable annuities and group pension contracts.
 
Effective May 1, 1997, the Company became a wholly-owned subsidiary of the newly
established Sun Life of Canada (U.S.) Holdings, Inc. ("Life Holdco"). On
December 18, 1997, Life Holdco became a wholly-owned subsidiary of the Sun Life
Assurance Company of Canada - U.S. Operations Holdings, Inc. ("US Holdco"). US
Holdco is a wholly-owned subsidiary of Sun Life Assurance Company of Canada
("SLOC"). Prior to December 18, 1997, Life Holdco was a direct wholly-owned
subsidiary of SLOC.
 
The Company, which is domiciled in the State of Delaware, prepares its financial
statements in accordance with statutory accounting practices prescribed or
permitted by the State of Delaware Insurance Department. Prescribed accounting
practices include practices described in a variety of publications of the
National Association of Insurance Commissioners ("NAIC"), as well as state laws,
regulations and general administrative rules. Permitted accounting practices
encompass all accounting practices not so prescribed. The permitted accounting
practices adopted by the Company are not material to the financial statements.
Prior to 1996, statutory accounting practices were recognized by the insurance
industry and the accounting profession as generally accepted accounting
principles for mutual life insurance companies and stock life insurance
companies wholly-owned by mutual life insurance companies. In April 1993, the
Financial Accounting Standards Board ("FASB") issued an interpretation (the
"Interpretation"), that became effective in 1996, which changed the previous
practice of mutual life insurance companies (and stock life insurance companies
that are wholly-owned subsidiaries of mutual life insurance companies) with
respect to utilizing statutory basis financial statements for general purposes,
in that it will no longer allow such financial statements to be described as
having been prepared in conformity with generally accepted accounting principles
("GAAP"). Consequently, these financial statements prepared in conformity with
statutory accounting practices, as described above, vary from and are not
intended to present the Company's financial position, results of operations or
cash flow in conformity with generally accepted accounting principles. (See Note
20 for further discussion relative to the Company's basis of financial statement
presentation.) The effects on the financial statements of the variances between
the statutory basis of accounting and GAAP, although not reasonably
determinable, are presumed to be material.
 
INVESTED ASSETS
 
Bonds are carried at cost, adjusted for amortization of premium or accrual of
discount. Investments in non-insurance subsidiaries are carried on the equity
basis. Investments in mortgage backed securities are generally carried at
amortized cost. Changes in prepayment assumptions and resulting cash flows are
evaluated periodically. The adjusted yield is used to calculate investment
income in future periods. If current book value exceeds future undiscounted cash
flows, a realized capital loss is recorded and amortized through IMR.

NOTES TO STATUTORY FINANCIAL STATEMENTS (CONTINUED)
YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996
 
1.  DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING
POLICIES (CONTINUED):
Investments in insurance subsidiaries are carried at their statutory surplus
values. Mortgage loans acquired at a premium or discount are carried at
amortized values and other mortgage loans are carried at the amounts of the
unpaid balances. Real estate investments are carried at the lower of cost,
adjusted for accumulated depreciation or appraised value, less encumbrances.
Short-term investments are carried at amortized cost, which approximates fair
value. Depreciation of buildings and improvements is calculated using the
straight-line method over the estimated useful life of the property, generally
40 to 50 years.
 
POLICY AND CONTRACT RESERVES
 
The reserves for life insurance and annuity contracts, developed by accepted
actuarial methods, have been established and maintained on the basis of
published mortality tables using assumed interest rates and valuation methods
that will provide reserves at least as great as those required by law and
contract provisions.
 
INCOME AND EXPENSES
 
For life and annuity contracts, premiums are recognized as revenues over the
premium paying period, whereas commissions and other costs applicable to the
acquisition of new business are charged to operations as incurred.
 
SEPARATE ACCOUNTS
 
The Company has established unitized separate accounts applicable to various
classes of contracts providing for variable benefits. Contracts for which funds
are invested in separate accounts include variable life insurance and individual
and group qualified and non-qualified variable annuity contracts.
 
Assets and liabilities of the separate accounts, representing net deposits and
accumulated net investment earnings less fees, held primarily for the benefit of
contract holders, are shown as separate captions in the financial statements.
Assets held in the separate accounts are carried at market value as determined
by quoted market prices of the underlying investments.
 
The Company has also established a non-unitized separate account for amounts
allocated to the fixed portion of certain combination fixed/variable deferred
annuity contracts. The assets of this account are available to fund general
account liabilities, and general account assets are available to fund
liabilities of this account.
 
Gains (losses) from mortality experience and investment experience of the
separate accounts, not applicable to contract owners, are transferred to (from)
the general account. Accumulated gains (losses) that have not been transferred
are recorded as a payable (receivable) to (from) the general account. Amounts
payable to the general account of the Company were $361,863,000 in 1998 and
$284,078,000 in 1997.
 
CHANGES IN ACCOUNTING PRINCIPLES AND REPORTING
 
As described more fully in Note 10, during 1997 the Company changed certain
assumptions used in determining actuarial reserves.

1.  DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING
POLICIES (CONTINUED):
In March 1998, the National Association of Insurance Commissioners adopted the
Codification of Statutory Accounting Principles ("Codification"). The
Codification, which is intended to standardize regulatory accounting and
reporting for the insurance industry, is proposed to be effective January 1,
2001. However, statutory accounting principles will continue to be established
by individual state laws and permitted practices and it is uncertain when, or
if, the state of Delaware will require adoption of Codification for the
preparation of statutory financial statements. The Company has not finalized the
quantification of the effects of Codification on its statutory financial
statements.
 
OTHER
 
Preparation of the financial statements requires management to make estimates
and assumptions that affect reported amounts of assets, liabilities, revenues
and expenses. Actual results could differ from those estimates.
 
Certain prior year amounts have been reclassified to conform to amounts as
presented in the current year.

Realized capital gains and losses on bonds and mortgages and interest rate swaps
which relate to changes in levels of interest rates are charged or credited to
an interest maintenance reserve ("IMR") and amortized into income over the
remaining contractual life of the security sold. The net realized capital gains
credited to the interest maintenance reserve were $8,943,000 in 1998, $6,321,000
in 1997, and $7,710,000 in 1996. All gains and losses are transferred net of
applicable income taxes.

8.  DERIVATIVES
 
The Company uses derivative instruments for interest rate risk management
purposes, including hedges against specific interest rate risk and to minimize
the Company's exposure to fluctuations in interest rates. The Company's use of
derivatives has included U.S. Treasury futures, conventional interest rate
swaps, and forward spread lock interest rate swaps.
 
In the case of interest rate futures, gains or losses on contracts that qualify
as hedges are deferred until the earliest of the completion of the hedging
transaction, determination that the transaction will no longer take place, or
determination that the hedge is no longer effective. Upon completion of the
hedge, where it is impractical to allocate gains or losses to specific hedged
assets or liabilities, gains or losses are deferred in IMR and amortized over
the remaining life of the hedged assets. At December 31, 1998 and 1997 there
were no futures contracts outstanding.
 
In the case of interest rate and foreign currency swap agreements and forward
spread lock interest rate swap agreements, gains or losses on terminated swaps
are deferred in the IMR and amortized over the shorter of the remaining life of
the hedged asset sold or the remaining term of the swap contract. The net
differential to be paid or received on interest rate swaps is recorded monthly
as interest rates change.

The market value of swaps is the estimated amount that the Company would receive
or pay on termination or sale, taking into account current interest rates and
the current credit worthiness of the counterparties. The Company is exposed to
potential credit loss in the event of nonperformance by counterparties. The
counterparties are major financial institutions and management believes that the
risk of incurring losses related to credit risk is remote.
 
9.  LEVERAGED LEASES
 
The Company is a lessor in a leveraged lease agreement entered into on October
21, 1994, under which equipment having an estimated economic life of 25-40 years
was leased for a term of 9.75 years. The Company's equity investment represented
22.9% of the purchase price of the equipment. The balance of the purchase price
was furnished by third-party long-term debt financing, collateralized by the
equipment and non-recourse to the Company. At the end of the lease term, the
Master Lessee may exercise a fixed price purchase option to purchase the
equipment.

10. REINSURANCE
 
The Company has agreements with SLOC which provide that SLOC will reinsure the
mortality risks of the individual life insurance contracts sold by the Company.
Under these agreements basic death benefits and supplementary benefits are
reinsured on a yearly renewable term basis and coinsurance basis, respectively.
Reinsurance transactions under these agreements had the effect of decreasing
income from operations by approximately $2,128,000, $1,381,000 and $1,603,000
for the years ended December 31, 1998, 1997 and 1996, respectively.
 
Effective January 1, 1991, the Company entered into an agreement with SLOC under
which certain individual life insurance contracts issued by SLOC were reinsured
by the Company on a 90% coinsurance basis. During 1997 SLOC changed certain
assumptions used in determining the gross and the ceded reserve balance. The
Company reflected the effect of the changes in assumptions to its assumed
reserves as a direct credit to surplus. The effect of the change was a
$39,016,000 decrease in reserves. Also, the agreement required SLOC to reinsure
the mortality risks in excess of $500,000 per policy for the individual life
insurance contracts assumed by the Company. Such death benefits are reinsured on
a yearly renewable term basis. The life reinsurance assumed agreement required
the reinsurer to withhold funds in amounts equal to the reserves assumed. These
agreements had the effect of increasing income from operations by approximately
$24,579,000, $37,050,000 and $35,161,000 for the years ended December 31, 1998,
1997 and 1996, respectively. The Company terminated this agreement effective
October 1, 1998, resulting in an increase in income from operations of
$65,679,000 which included a cash settlement.

13. RETIREMENT PLANS
 
The Company participates with SLOC in a noncontributory defined benefit pension
plan covering essentially all employees. The benefits are based on years of
service and compensation.
 
The funding policy for the pension plan is to contribute an amount which at
least satisfies the minimum amount required by ERISA; currently, the plan is
fully funded. The Company is charged for its share of the pension cost based
upon its covered participants. Pension plan assets consist principally of
separate accounts of SLOC.
 
The Company's share of the group's accrued pension cost was $1,178,000 and
$593,000 at December 31, 1998 and 1997, respectively. The Company's share of net
periodic pension cost was $586,000, $146,000 and $27,000, for 1998, 1997 and
1996, respectively.
 
The Company also participates with SLOC and certain affiliates in a 401(k)
savings plan for which substantially all employees are eligible. The Company
matches, up to specified amounts, employees' contributions to the plan. Company
contributions were $231,000, $259,000 and $233,000 for the years ended December
31, 1998, 1997 and 1996, respectively.

13. RETIREMENT PLANS (CONTINUED):
OTHER POST-RETIREMENT BENEFIT PLANS
 
In addition to pension benefits the Company provides certain health, dental, and
life insurance benefits ("post-retirement benefits") for retired employees and
dependents. Substantially all employees may become eligible for these benefits
if they reach normal retirement age while working for the Company, or retire
early upon satisfying an alternate age plus service condition. Life insurance
benefits are generally set at a fixed amount.
 
Effective January 1, 1993, the Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 106, "Employer's Accounting for Postretirement Benefits
Other Than Pensions." SFAS No. 106 requires an accrual of the estimated cost of
retiree benefit payments during the years the employee provides services. SFAS
No. 106 allows recognition of the cumulative effect of the liability in the year
of adoption or the amortization of the obligation over a period of up to 20
years. The obligation of approximately $455,000 is recognized over a period of
ten years. The Company's cash flows are not affected by implementation of this
standard, but implementation decreased net income by $95,000, $117,000, and
$8,000 for the years ended December 31, 1998, 1997, and 1996, respectively. The
Company's post retirement health, dental and life insurance benefits currently
are not funded.

The major methods and assumptions used in estimating the fair values of
financial instruments are as follows:
 
The fair values of short-term bonds are estimated to be the amortized cost. The
fair values of long-term bonds which are publicly traded are based upon market
prices or dealer quotes. For privately placed bonds, fair values are estimated
by taking into account prices for publicly traded bonds of similar credit risk
and maturity and repayment and liquidity characteristics.
 
The fair values of the Company's general account insurance reserves and
liabilities under investment-type contracts (insurance, annuity and pension
contracts that do not involve mortality or morbidity risks) are estimated using
discounted cash flow analyses or surrender values. Those contracts that are
deemed to have short-term guarantees have a carrying amount equal to the
estimated market value.
 
The fair values of mortgages are estimated by discounting future cash flows
using current rates at which similar loans would be made to borrowers with
similar credit ratings and for the same remaining maturities.
 
The fair values of derivative financial instruments are estimated using the
process described in Note 8.

15. STATUTORY INVESTMENT VALUATION RESERVES
 
The asset valuation reserve ("AVR") provides a reserve for losses from
investments in bonds, stocks, mortgage loans, real estate and other invested
assets with related increases or decreases being recorded directly to surplus.
 
Realized capital gains and losses on bonds and mortgages which relate to changes
in levels of interest rates are charged or credited to an interest maintenance
reserve ("IMR") and amortized into income over the remaining contractual life of
the security sold.
 
The table shown below presents changes in the major elements of the AVR and IMR.

16. FEDERAL INCOME TAXES
 
The Company and its subsidiaries file a consolidated federal income tax return.
Federal income taxes are calculated for the consolidated group based upon
amounts determined to be payable as a result of operations within the current
year. No provision is recognized for timing differences which may exist between
financial statement and taxable income. Such timing differences include
reserves, depreciation and accrual of market discount on bonds. Cash payments
for federal income taxes were approximately $48,144,000, $31,000,000 and
$19,264,000 for the years ended December 31, 1998, 1997 and 1996, respectively.
The Company is currently undergoing an audit by the Internal Revenue Service.
The Company believes that there will be no material audit adjustments for the
periods under examination.
 
17. SURPLUS NOTES AND NOTES RECEIVABLE (PAYABLE)
 
On December 22, 1997, the Company issued a $250,000,000 surplus note to Life
Holdco. This note has an interest rate of 8.625% and is due on or after November
6, 2027.
 
On May 9, 1997, the Company issued a short-term note of $600,000,000 to Life
Holdco at an interest rate of 5.10%, which was extended at various interest
rates. This note was repaid on December 22, 1997.
 
On December 19, 1995, the Company issued surplus notes totaling $315,000,000 to
an affiliate, Sun Canada Financial Co., at interest rates between 5.75% and
7.25%. Of these notes, $157,500,000 will mature in the year 2007 and
$157,500,000 will mature in the year 2015. Interest on these notes is payable
semiannually.

17. SURPLUS NOTES AND NOTES RECEIVABLE (PAYABLE) (CONTINUED):
Principal and interest on surplus notes are payable only to the extent that the
Company meets specified requirements regarding free surplus exclusive of the
principal amount and accrued interest, if any, on these notes and with the
consent of the Delaware Insurance Commissioner.
 
The Company accrued $4,259,000 and $ 964,000 for interest on surplus notes for
the years ended December 31, 1998 and 1997, respectively.
 
The Company accrued $4,259,000 and $964,000 for interest on surplus notes for
the years ended December 31, 1998 and 1997, respectively.
 
The Company expensed $44,903,000, $42,481,000 and $23,061,000 for interest on
surplus notes and notes payable for the years ended December 31, 1998, 1997 and
1996, respectively.
 
18. TRANSACTIONS WITH AFFILIATES
 
The Company has an agreement with SLOC which provides that SLOC will furnish, as
requested, personnel as well as certain services and facilities on a
cost-reimbursement basis. Expenses under this agreement amounted to
approximately $16,344,000 in 1998, $15,997,000 in 1997, and $20,192,000 in 1996.
 
The Company leases office space to SLOC under lease agreements with terms
expiring in September, 1999 and options to extend the terms for each of thirteen
successive five-year terms at fair market rental not to exceed 125% of the fixed
rent for the term which is ending. Rent received by the Company under the leases
for 1998 amounted to approximately $6,856,000.
 
19. RISK-BASED CAPITAL
 
Effective December 31, 1993, the NAIC adopted risk-based capital requirements
for life insurance companies. The risk-based capital requirements provide a
method for measuring the minimum acceptable amount of adjusted capital that a
life insurer should have, as determined under statutory accounting practices,
taking into account the risk characteristics of its investments and products.
The Company has met the minimum risk-based capital requirements at December 31,
1998, 1997 and 1996.
 
20. ACCOUNTING POLICIES AND PRINCIPLES
 
The financial statements of the Company have been prepared on the basis of
statutory accounting practices which, prior to 1996, were considered by the
insurance industry and the accounting profession to be in accordance with GAAP
for mutual life insurance companies. The primary differences between statutory
accounting practices and GAAP are described as follows. Under statutory
accounting practices, financial statements are not consolidated and investments
in subsidiaries are shown at net equity value. Accordingly, the assets,
liabilities and results of operations of the Company's subsidiaries are not
consolidated with the assets, liabilities and results of operations,
respectively, of the Company. Changes in net equity value of the common stock of
the Company's United States life insurance subsidiaries are directly reflected
in the Company's surplus. Changes in the net equity value of the

20. ACCOUNTING POLICIES AND PRINCIPLES (CONTINUED):
common stock of all other subsidiaries are directly reflected in the Company's
Asset Valuation Reserve. Dividends paid by subsidiaries to the Company are
included in the Company's net investment income.
 
Other differences between statutory accounting practices and GAAP include the
following: statutory accounting practices do not recognize the following assets
or liabilities which are reflected under GAAP: deferred policy acquisition
costs, deferred federal income taxes and statutory nonadmitted assets. Asset
Valuation Reserves and Interest Maintenance Reserves are established under
statutory accounting practices but not under GAAP. Methods for calculating real
estate depreciation and investment valuation allowances differ under statutory
accounting practices and GAAP. Actuarial assumptions and reserving methods
differ under statutory accounting practices and GAAP. Premiums for universal
life and investment-type products are recognized as income for statutory
purposes and as deposits to policyholders' accounts for GAAP.
 
Because the Company's management uses financial information prepared in
conformity with accounting principles generally accepted in Canada in the normal
course of business, the management of Sun Life Assurance Company of Canada
(U.S.) has determined that the cost of complying with Statement No. 120,
"Accounting and Reporting by Mutual Insurance Enterprises and by Insurance
Enterprises for Certain Long Duration Participating Contracts", exceeds the
benefits that the Company, or the users of its financial statements, would
experience. Consequently, the Company has elected not to apply such standards in
the preparation of these financial statements.

INDEPENDENT AUDITORS' REPORT
 
TO THE BOARD OF DIRECTORS AND STOCKHOLDERS
 
SUN LIFE ASSURANCE COMPANY OF CANADA (U.S.)
 
We have audited the accompanying statutory statements of admitted assets,
liabilities and capital stock and surplus of Sun Life Assurance Company of
Canada (U.S.) (the "Company") as of December 31, 1998 and 1997, and the related
statutory statements of operations, changes in capital stock and surplus, and
cash flow for each of the three years in the period ended December 31, 1998.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
As described more fully in Notes 1 and 20 to the financial statements, the
Company prepared these financial statements using accounting practices
prescribed or permitted by the Insurance Department of the State of Delaware,
which is a comprehensive basis of accounting other than generally accepted
accounting principles. The effects on the financial statements of the
differences between the statutory basis of accounting and generally accepted
accounting principles, although not reasonably determinable, are presumed to be
material.
 
In our opinion, the statutory financial statements referred to above present
fairly, in all material respects, the admitted assets, liabilities, and capital
stock and surplus of Sun Life Assurance Company of Canada (U.S.) as of December
31, 1998 and 1997, and the results of its operations and its cash flow for each
of the three years in the period ended December 31, 1998 on the basis of
accounting described in Notes 1 and 20.
 
However, because of the differences between the two bases of accounting referred
to in the second preceding paragraph, in our opinion, the statutory financial
statements referred to above do not present fairly, in conformity with generally
accepted accounting principles, the financial position of Sun Life Assurance
Company of Canada (U.S.) as of December 31, 1998 and 1997 or the results of its
operations or its cash flow for each of the three years in the period ended
December 31, 1998.
 
As management has stated in Note 20, because the Company's management uses
financial information prepared in accordance with accounting principles
generally accepted in Canada in the normal course of business, the management of
Sun Life Assurance Company of Canada (U.S.) has determined that the cost of
complying with Statement No. 120, ACCOUNTING AND REPORTING BY MUTUAL LIFE
INSURANCE ENTERPRISES AND BY INSURANCE ENTERPRISES FOR CERTAIN LONG-DURATION
PARTICIPATING CONTRACTS, would exceed the benefits that the Company, or the
users of its financial statements, would experience. Consequently, the Company
has elected not to apply such standards in the preparation of these financial
statements.

                                                                      APPENDIX B
    
 
              HYPOTHETICAL ILLUSTRATIONS OF CASH SURRENDER VALUES,
                       ACCOUNT VALUES AND DEATH BENEFITS
 
    The Tables on the following pages illustrate the way in which a Policy's
Death Benefit, Account Value and Cash Surrender Value could vary over an
extended period of time. They assume that all premiums are allocated to and
remain in the Variable Account for the entire period shown and are based on
hypothetical gross annual investment returns for the Funds (i.e., investment
income and capital gains and losses, realized or unrealized) equivalent to
constant gross annual rates of 0%, 6%, and 12% over the periods indicated.
 
    All Tables illustrate a Policy where the insured is a male, Issue Age 45, in
the preferred (non-tobacco) rate class. These illustrations all assume a Total
Face Amount of $500,000 and payment of an annual premium of $12,600. Tables 1,
2, 5 and 6 assume a Specified Face Amount of $500,000. Tables 3 and 4 assume a
Specified Face Amount of $50,000 and an APB Rider Face Amount of $450,000.
Tables 1 and 2 are based on guaranteed issue underwriting, Death Benefit Option
A, the Cash Value Accumulation Test and a Specified Face Amount of $500,000.
Tables 3 and 4 are based on the same assumptions, except that the Total Face
Amount reflects a Specified Face Amount of $50,000 and an APB Rider Face Amount
of $450,000. Tables 5 and 6 are based on full medical underwriting, Death
Benefit Option B, the Guideline Premium Test, and a Specified Face Amount of
$500,000. Tables 1, 3 and 5 differ from Tables 2, 4 and 6, respectively, only in
that Tables 1, 3 and 5 reflect the deduction of current policy charges as
outlined below, while Tables 2, 4 and 6 reflect the deduction of policy charges
at the guaranteed maximum rates (except that Kentucky policyowners will have
higher premium tax deductions than those reflected).
 
    The Account Values and Death Benefits would be different from those shown if
the gross annual investment rates of return averaged 0%, 6%, and 12% over a
period of years, but fluctuated above or below such averages for individual
Policy Years. The values would also be different depending on the allocation of
a Policy's total Account Value among the Sub-Accounts of the Variable Account,
if the actual rates of return averaged 0%, 6% or 12%, but the rates of each Fund
varied above and below such averages.
 
   
    The amounts shown for the Death Benefits and Account Values take into
account all charges and deductions imposed under the Policy based on the
assumptions set forth in the Tables. These include: Expense Charges Applied to
Premium, assuming a premium tax rate of 2% for Tables 1, 3 and 5 and 4% for
Tables 2, 4 and 6. The Daily Risk Percentage charged against the Separate
Account for mortality and expense risks, at an effective annual rate of 0.60%
for the first 10 Policy Years, 0.20% for Policy Years 11 through 20, and 0.10%
thereafter for Tables 1, 3 and 5, and 0.90% for all Policy Years for Tables 2, 4
and 6; the Monthly Expense Charge of $13.75 per month for the first Policy Year
and $7.50 per month thereafter for Tables 1, 3 and 5, and $13.75 per month for
all Policy Years for Tables 2, 4, and 6; and the Monthly Cost of Insurance based
on current charges for Tables 1, 3 and 5, and guaranteed charges for Tables 2,
4, and 6.
    
 
   
    The amounts shown in the Tables also take into account the Funds' advisory
fees and operating expenses, which are assumed to be at an annual rate of
0.7900% of the average daily net assets of each Fund. This is based upon a
simple average of the advisory fees and expenses of all the Funds for the most
recent fiscal year taking into account any applicable expense caps or expense
reimbursement arrangements. Actual fees and expenses of the Funds may be more or
less than 0.7900%, will vary from year to year, and will depend upon how Account
Value is allocated among the Sub-Accounts. See the individual prospectus for
each Fund for more information on fund expenses.
    
<PAGE>
   
    The gross annual rates of investment return of 0%, 6% and 12% correspond to
net annual rates of -1.38%, 4.58%, and 10.55%, respectively, during the first 10
Policy Years, -0.99%, 5.00%, and 10.99% for Policy Years 11 through 20, and
- -0.89%, 5.10%, and 11.10%, respectively, thereafter taking into account the
current Daily Risk Percentage and the assumed 0.7900% charge for the Funds'
advisory fees and operating expenses; and -1.66%, 4.29%, and 10.24%,
respectively taking into account the guaranteed Daily Risk Percentage.
    
 
    The hypothetical returns shown in the Tables do not reflect any charges for
income taxes against the Variable Account since no charges are currently made.
If, in the future, such charges are made, in order to produce the illustrated
death benefits and cash values, the gross annual investment rate of return would
have to exceed 0%, 6%, or 12% by a sufficient amount to cover the tax charges.
 
    The second column of each Table shows the amount which would accumulate if
an amount equal to each premium were invested and earned interest, after taxes,
at 5% per year, compounded annually.
 
    We will furnish upon request a comparable Table using any specific set of
circumstances. In addition to a Table assuming policy charges at their maximum,
we will furnish a Table assuming current policy charges.

    THE HYPOTHETICAL INVESTMENT RATES OF RETURN ARE ILLUSTRATIVE ONLY, AND
SHOULD NOT BE DEEMED A REPRESENTATION OF PAST OR FUTURE INVESTMENT RATES OF
RETURN. ACTUAL INVESTMENT RESULTS MAY BE MORE OR LESS THAN THOSE SHOWN, AND WILL
DEPEND ON A NUMBER OF FACTORS, INCLUDING THE INVESTMENT ALLOCATIONS BY A POLICY
OWNER, AND THE DIFFERENT INVESTMENT RATES OF RETURN FOR THE FUNDS. THE CASH
SURRENDER VALUE AND DEATH BENEFIT FOR A POLICY WOULD BE DIFFERENT FROM THOSE
SHOWN IF THE ACTUAL RATES OF INVESTMENT RETURN AVERAGED 0%, 6%, AND 12% OVER A
PERIOD OF YEARS, BUT FLUCTUATED ABOVE AND BELOW THOSE AVERAGES FOR INDIVIDUAL
POLICY YEARS. THEY WOULD ALSO BE DIFFERENT IF ANY POLICY LOANS OR PARTIAL
SURRENDERS WERE MADE. NO REPRESENTATIONS CAN BE MADE THAT THESE HYPOTHETICAL
INVESTMENT RATES OF RETURN CAN BE ACHIEVED FOR ANY ONE YEAR OR SUSTAINED OVER
ANY PERIOD OF TIME.

                             UNDERTAKING TO FILE REPORTS

     Subject to the terms and conditions of Section 15(d) of the Securities
Exchange Act of 1934, the undersigned registrant hereby undertakes to file with
the Securities and Exchange Commission such supplementary and periodic
information, documents, and reports as may be prescribed by any rule or
regulation of the Commission heretofore or hereafter duly adopted pursuant to
authority conferred in that section.

                       REPRESENTATION OF REASONABLENESS OF FEES

     Sun Life Assurance Company of Canada (U.S.) hereby represents that the
aggregate fees and charges under the Policy are reasonable in relation to the
services rendered, the expenses expected to be incurred, and the risks assumed
by Sun Life Assurance Company of Canada (U.S.).

                            UNDERTAKING ON INDEMNIFICATION

     Insofar as indemnification for liability arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
depositor pursuant to its certificate of incorporation, bylaws, or otherwise,
the depositor has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
depositor of expenses incurred or paid by a director, officer or controlling
person of the depositor in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the depositor will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the act and will
be governed by the final adjudication of such issue.

                               PARTICIPATION AGREEMENT


     THIS AGREEMENT, made and entered into as of the 17th day of February, 1998
("Agreement"), by and among AIM Variable Insurance Funds, Inc., a Maryland
corporation ("AVIF"); A I M Distributors, Inc., a Delaware corporation ("AIM");
Sun Life Assurance Company of Canada (U.S.), a Delaware life insurance company
("Sun Life"), on behalf of  itself and each of its segregated asset accounts
listed in Schedule A hereto, as the parties hereto may amend from time to time
(each, an "Account," and collectively, the "Accounts"); and Clarendon Insurance
Agency, Inc. ("Clarendon"), a Massachusetts corporation, a subsidiary of Sun
Life and the principal underwriter of the Contracts (collectively, the
"Parties").


                                  WITNESSETH THAT:

     WHEREAS, AVIF is registered with the Securities and Exchange Commission
("SEC") as an open-end management investment company under the Investment
Company Act of 1940, as amended (the "1940 Act"); and

     WHEREAS, AVIF currently consists of nine separate series ("Series"), shares
("Shares") of each of which are registered under the Securities Act of 1933, as
amended (the "1933 Act") and are currently sold to one or more separate accounts
of life insurance companies to fund benefits under variable annuity contracts
and variable life insurance contracts; and

     WHEREAS, AVIF will make Shares of each Series listed on Schedule A hereto
as the Parties hereto may amend from time to time (each a "Fund"; reference
herein to "AVIF" includes reference to each Fund, to the extent the context
requires) available for purchase by the Accounts; and

     WHEREAS, Sun Life will be the issuer of certain variable annuity contracts
and variable life insurance contracts ("Contracts")  as set forth on Schedule A
hereto, as the Parties hereto may amend from time to time, which Contracts
(hereinafter collectively, the "Contracts"), if required by applicable law, will
be registered under the 1933 Act; and

     WHEREAS, Sun Life will fund the Contracts through the Accounts, each of
which may be divided into two or more subaccounts ("Subaccounts"; reference
herein to an "Account" includes reference to each Subaccount thereof to the
extent the context requires); and

     WHEREAS, Sun Life will serve as the depositor of the Accounts, each of
which is registered as a unit investment trust investment company under the 1940
Act (or exempt therefrom), and the security interests deemed to be issued by the
Accounts under the Contracts will be registered as securities under the 1933 Act
(or exempt therefrom); and


                                          1
<PAGE>

     WHEREAS, to the extent permitted by applicable insurance laws and
regulations, Sun Life intends to purchase Shares of one or more of the Funds on
behalf of the Accounts to fund the Contracts; and

     WHEREAS, Clarendon is a broker-dealer registered with the SEC under the
Securities Exchange Act of 1934 ("1934 Act") and a member in good standing of
the National Association of Securities Dealers, Inc. ("NASD");

     NOW, THEREFORE, in consideration of the mutual benefits and promises
contained herein, the Parties hereto agree as follows:


                             SECTION 1.  AVAILABLE FUNDS

     1.1   AVAILABILITY.

     AVIF will make Shares of each Fund available to Sun Life for purchase and
redemption at net asset value and with no sales charges, subject to the terms
and conditions of this Agreement.  The Board of Directors of AVIF may refuse to
sell Shares of any Fund to any person, or suspend or terminate the offering of
Shares of any Fund if such action is required by law or by regulatory
authorities having jurisdiction or if, in the sole discretion of the Directors
acting in good faith and in light of their fiduciary duties under federal and
any applicable state laws, such action is deemed in the best interests of the
shareholders of such Fund.

     1.2   ADDITION, DELETION OR MODIFICATION OF FUNDS.

     The Parties hereto may agree, from time to time, to add other Funds to
provide additional funding media for the Contracts, or to delete, combine, or
modify existing Funds, by amending Schedule A hereto.  Upon such amendment to
Schedule A, any applicable reference to a Fund, AVIF, or its Shares herein shall
include a reference to any such additional Fund.  Schedule A, as amended from
time to time, is incorporated herein by reference and is a part hereof.

     1.3   NO SALES TO THE GENERAL PUBLIC.

     AVIF represents and warrants that no Shares of any Fund have been or will
be sold to the general public.


                         SECTION 2.  PROCESSING TRANSACTIONS

     2.1   TIMELY PRICING AND ORDERS.

     (a)   AVIF or its designated agent will use its best efforts to provide Sun
Life with the net asset value per Share for each Fund by 5:30 p.m. Central Time
on each Business Day.  As used herein, "Business Day" shall mean any day on
which (i) the New York Stock Exchange is open for


                                          2
<PAGE>

regular trading,  (ii) AVIF calculates the Fund's net asset value, and (iii) Sun
Life is open for business.

     (b)   Sun Life will use the data provided by AVIF each Business Day
pursuant to paragraph (a) immediately above to calculate Account unit values and
to process transactions that receive that same Business Day's Account unit
values.  Sun Life will perform such Account processing the same Business Day,
and will place corresponding orders to purchase or redeem Shares with AVIF by
9:00 a.m. Central Time the following Business Day; PROVIDED, however, that AVIF
shall provide additional time to Sun Life in the event that AVIF is unable to
meet the 5:30 p.m. Central Time stated in paragraph (a) immediately above.  Such
additional time shall be equal to the additional time that AVIF takes to make
the net asset values available to Sun Life.

     (c)   With respect to payment of the purchase price by Sun Life and of
redemption proceeds by AVIF, Sun Life and AVIF shall net purchase and redemption
orders with respect to each Fund and shall transmit one net payment per Fund in
accordance with Section 2.2, below.

     (d)   If AVIF provides materially incorrect Share net asset value
information (as determined under SEC guidelines), Sun Life shall be entitled to
an adjustment to the number of Shares purchased or redeemed to reflect the
correct net asset value per Share.  Any material error in the calculation or
reporting of net asset value per Share, dividend or capital gain information
shall be reported promptly upon discovery to Sun Life.

     2.2   TIMELY PAYMENTS.

     Sun Life will wire payment for net purchases to a custodial account
designated by AVIF by 1:00 p.m. Central Time on the same day as the order for
Shares is placed, to the extent practicable.  AVIF will wire payment for net
redemptions to an account designated by Sun Life by 1:00 p.m. Central Time on
the same day as the Order is placed, to the extent practicable, but in any event
within five (5) calendar days after the date the order is placed in order to
enable Sun Life to pay redemption proceeds within the time specified in Section
22(e) of the 1940 Act or such shorter period of time as may be required by law.

     2.3   APPLICABLE PRICE.

     (a)   Share purchase payments and redemption orders that result from
purchase  payments, premium payments, surrenders and other transactions under
Contracts (collectively, "Contract transactions") and that Sun Life receives
prior to the close of regular trading on the New York Stock Exchange on a
Business Day will be executed at the net asset values of the appropriate Funds
next computed after receipt by AVIF or its designated agent of the orders.  For
purposes of this Section 2.3(a), Sun Life shall be the designated agent of AVIF
for receipt of orders relating to Contract transactions on each Business Day and
receipt by such designated agent shall constitute receipt by AVIF; PROVIDED that
AVIF receives notice of such orders by 9:00 a.m. Central Time on the next
following Business Day or such later time as computed in accordance with Section
2.1(b) hereof.  AVIF will acknowledge and verify receipt of such orders by 12:00
p.m. Central Time on each business day on which orders are received.


                                          3
<PAGE>

     (b)   All other Share purchases and redemptions by Sun Life will be
effected at the net asset values of the appropriate Funds next computed after
receipt by AVIF or its designated agent of the order therefor, and such orders
will be irrevocable.

     2.4   DIVIDENDS AND DISTRIBUTIONS.

     AVIF will furnish notice by wire or telephone (followed by written
confirmation) on or prior to the payment date to Sun Life of any income
dividends or capital gain distributions payable on the Shares of any Fund.  Sun
Life hereby elects to reinvest all dividends and capital gains distributions in
additional Shares of the corresponding Fund at the ex-dividend date net asset
values until Sun Life otherwise notifies AVIF in writing, it being agreed by the
Parties that the ex-dividend date and the payment date with respect to any
dividend or distribution will be the same Business Day.  Sun Life reserves the
right to revoke this election and to receive all such income dividends and
capital gain distributions in cash.

                                          4
<PAGE>

     (a)   AVIF represents and warrants that each Fund is currently qualified as
a regulated investment company ("RIC") under Subchapter M of the Internal
Revenue Code of 1986, as amended (the "Code"), and represents that it will
qualify and maintain qualification of each Fund as a RIC.  AVIF will notify Sun
Life immediately upon having a reasonable basis for believing that a Fund has
ceased to so qualify or that it might not so qualify in the future.

     (b)   AVIF represents that it will comply and maintain each Fund's
compliance with the diversification requirements set forth in Section 817(h) of
the Code and Section 1.817-5(b) of the regulations under the Code.  AVIF will
notify Sun Life immediately upon having a reasonable basis for believing that a
Fund has ceased to so comply or that a Fund might not so comply in the future.
In the event of a breach of this Section 4.1(b) by AVIF, it will take all
reasonable steps to adequately diversify the Fund so as to achieve compliance
within the grace period afforded by Section 1.817-5 of the regulations under the
Code.

     (c)   Notwithstanding Section 12.2 of this Agreement, Sun Life agrees that
if the Internal Revenue Service ("IRS") asserts in writing in connection with
any governmental audit or review of Sun Life or, to Sun Life's knowledge, of any
Participant, that any Fund has failed to comply with the diversification
requirements of Subchapter M or Section 817(h) of the Code or Sun Life otherwise
becomes aware of any facts that could give rise to any claim against AVIF or its
affiliates as a result of such a failure or alleged failure:

             (i)  Sun Life shall promptly notify AVIF of such assertion or
                  potential claim (subject to the confidentiality provisions of
                  Section 18 as to any Participant);

            (ii)  Sun Life shall consult with AVIF as to how to minimize any
                  liability that may arise as a result of such failure or
                  alleged failure;

           (iii)  Sun Life shall, in good faith and to the extent not
                  inconsistent with its fiduciary duties to its Contract owners,
                  use its best efforts to minimize any liability of AVIF or its
                  affiliates resulting from such failure, including, without
                  limitation, demonstrating, pursuant to Treasury Regulations
                  Section 1.817-5(a)(2), to the Commissioner of the IRS that
                  such failure was inadvertent;

            (iv)  Sun Life shall permit AVIF, its affiliates and their legal and
                  accounting advisors to participate, at their sole expense, in
                  any conferences, settlement discussions or other
                  administrative or judicial proceeding or contests (including
                  judicial appeals thereof) with the IRS, any Participant or any
                  other claimant regarding any claims that could give rise to
                  liability to AVIF or its affiliates as a result of such a
                  failure or alleged failure;  PROVIDED, however, that Sun Life
                  will retain control of the conduct of such conferences
                  discussions, proceedings, contests or appeals;

             (v)  any written materials to be submitted by Sun Life to the IRS,
                  any Participant or any other claimant in connection with any
                  of the foregoing proceedings or


                                          5
<PAGE>

                  contests (including, without limitation, any such materials to
                  be submitted to the IRS pursuant to Treasury Regulations
                  Section 1.817-5(a)(2)), (a) shall be provided by Sun Life to
                  AVIF (together with any supporting information or analysis);
                  subject to the confidentiality provisions of Section 18, at
                  least ten (10) business days or such shorter period to which
                  the Parties hereto agree prior to the day on which such
                  proposed materials are to be submitted, and (b) shall not be
                  submitted by Sun Life to any such person without the express
                  written consent of AVIF which shall not be unreasonably
                  withheld; PROVIDED, that in any event, each Party shall use
                  its best efforts to make, as promptly as possible, the
                  submissions to the Commissioner of the IRS contemplated by
                  paragraph (c)(iii) above;

            (vi)  Sun Life shall provide AVIF or its affiliates and their
                  accounting and legal advisors with such cooperation as AVIF
                  shall reasonably request (including, without limitation, by
                  permitting AVIF and its accounting and legal advisors to
                  review the relevant books and records of  Sun Life) in order
                  to facilitate review by AVIF or its advisors of any written
                  submissions provided to it pursuant to the preceding clause or
                  its assessment of the validity or amount of any claim against
                  its arising from such a failure or alleged failure;

           (vii)  Sun Life shall not with respect to any claim of the IRS or any
                  Participant that would give rise to a claim against AVIF or
                  its affiliates (a) compromise or settle any claim, (b) accept
                  any adjustment on audit, or (c) forego any allowable
                  administrative or judicial appeals, without the express
                  written consent of AVIF or its affiliates, which shall not be
                  unreasonably withheld, PROVIDED, that after exhausting all
                  administrative remedies, in the event of an adverse judicial
                  decision, Sun Life shall either (a) appeal such decision,
                  PROVIDED, that to the extent requested by Sun Life, AVIF or
                  its affiliates provides an opinion of independent counsel to
                  the effect that a reasonable basis exists for taking such
                  appeal, in which case the costs of such appeal shall be borne
                  equally by the Parties hereto, or (b) permit AVIF and its
                  affiliates to act in the name of Sun Life and to control the
                  conduct of such appeal pursuant to the last paragraph of this
                  Section 4.1(c), in which case the costs of such appeal shall
                  be borne by AVIF or its affiliates pursuant to that paragraph;
                  and

         (viii)   AVIF and its affiliates shall have no liability as a result of
                  such failure or alleged failure if Sun Life fails to comply
                  with any of the foregoing clauses (i) through (vii), and such
                  failure could be shown to have materially contributed to the
                  liability.

     Should AVIF or any of its affiliates refuse to give its written consent to
any compromise or settlement of any claim or liability hereunder,  Sun Life may,
in its discretion, authorize AVIF or its affiliates to act in the name of Sun
Life in, and to control the conduct of, such conferences, discussions,
proceedings, contests or appeals and all administrative or judicial appeals
thereof, and


                                          6
<PAGE>

in that event AVIF or its affiliates shall bear the fees and expenses associated
with the conduct of the proceedings that it is so authorized to control;
PROVIDED, that in no event shall Sun Life have any liability resulting from
AVIF's refusal to accept the proposed settlement or compromise with respect to
any failure to comply with the requirements of Subchapter M or Section 817(h) of
the Code caused by AVIF.  As used in this Agreement, the term "affiliates" shall
have the same meaning as "affiliated person" as defined in Section 2(a)(3) of
the 1940 Act.

     (d)   AVIF agrees to cooperate with Sun Life with respect to the matters
described in paragraphs (c)(i) through (vii) above.  AVIF further agrees that it
shall provide or cause to be provided to Sun Life, on a quarterly basis, written
confirmation of each Fund's compliance with the diversification requirements of
Subchapter M and Section 817(h) of the Code.

     (e)   Sun Life represents and warrants that the Contracts currently are and
will be treated as annuity contracts or life insurance contracts under
applicable provisions of the Code and that it will maintain such treatment; Sun
Life will notify AVIF immediately upon having a reasonable basis for believing
that any of the Contracts have ceased to be so treated or that they might not be
so treated in the future.

     (f)   Sun Life represents and warrants that each Account is a "segregated
asset account" and that interests in each Account are offered exclusively
through the purchase of or transfer into a "variable contract," within the
meaning of such terms under Section 817 of the Code and the regulations
thereunder.  Sun Life will continue to meet such definitional requirements, and
it will notify AVIF immediately upon having a reasonable basis for believing
that such requirements have ceased to be met or that they might not be met in
the future.

     4.2   INSURANCE AND CERTAIN OTHER LAWS.

     (a)   AVIF will use its best efforts to comply with any applicable state
insurance laws or regulations, to the extent specifically requested by Sun Life,
including, the furnishing of information not otherwise available to Sun Life
which is required by state insurance law to enable Sun Life to obtain the
authority needed to issue the Contracts in any applicable state.

     (b)   Sun Life represents and warrants that (i) it is an insurance company
duly organized, validly existing and in good standing under the laws of the
State of Delaware and has full corporate power, authority and legal right to

this Agreement, (ii) it has legally and validly established and maintains each
Account as a segregated asset account under Delaware law and the regulations
thereunder, and (iii) the Contracts comply in all material respects with all
other applicable federal and state laws and regulations.

     (c)   AVIF represents and warrants that it is a corporation  duly
organized, validly existing, and in good standing under the laws of the State of
Maryland and has full power, authority, and legal right to execute, deliver, and
perform its duties and comply with its obligations under this Agreement.

     (d)   AVIF currently does not intend to make any payments to finance
distribution expenses pursuant to Rule 12b-1 under the 1940 Act or otherwise,
although it reserves the right to make such  payments in the future.  To the
extent that it decides to finance distribution expenses pursuant to Rule 12b-1,
AVIF undertakes to have its Board of Directors, a majority of whom are not
"interested" persons of the Fund, formulate and approve any plan under Rule
12b-1 to finance distribution expenses.

     (e)   AVIF represents and warrants that all of its trustees, officers,

                                          8
<PAGE>

includes coverage for larceny and embezzlement and is issued by a reputable
bonding company.

     (a)   AVIF will immediately notify Sun Life of (i) the issuance by any
court or regulatory body of any stop order, cease and desist order, or other

material respects, issued and sold in accordance with applicable state and
federal law, or (b) such law precludes the use of such Shares as an underlying
investment medium of the Contracts issued or to be issued by Sun Life.  AVIF
will make every reasonable effort to prevent the issuance, with respect to any
Fund, of any such stop order, cease and desist order or similar order and, if
any such order is issued, to obtain the lifting thereof at the earliest possible

                         SECTION 5.  MIXED AND SHARED FUNDING

     5.1   GENERAL.

     The SEC has granted an order to AVIF exempting it from certain provisions
of the 1940 Act and rules thereunder so that AVIF may be available for
investment by certain other entities, including, without limitation, separate
accounts funding variable annuity contracts or variable life insurance
contracts, separate accounts of insurance companies unaffiliated with Sun Life,
and trustees of qualified pension and retirement plans (collectively, "Mixed and
Shared Funding").  The Parties recognize that the SEC has imposed terms and
conditions for such orders that are substantially identical to many of the
provisions of this Section 5.  Sections 5.2 through 5.8 below


                                          11
<PAGE>

shall apply pursuant to such an exemptive order granted to AVIF.  AVIF hereby
notifies Sun Life that, in the event that AVIF implements Mixed and Shared
Funding, it may be appropriate to include in the prospectus pursuant to which a
Contract is offered disclosure regarding the potential risks of Mixed and Shared
Funding.

     5.2   DISINTERESTED DIRECTORS.

     AVIF agrees that its Board of Directors shall at all times consist of
directors a majority of whom (the "Disinterested Directors") are not interested
persons of AVIF within the meaning of Section 2(a)(19) of the 1940 Act and the
Rules thereunder and as modified by any applicable orders of the SEC, except
that if this condition is not met by reason of the death, disqualification, or
bona fide resignation of any director, then the operation of this condition
shall be suspended (a) for a period of forty-five (45) days if the vacancy or
vacancies may be filled by the Board; (b) for a period of sixty (60) days if a
vote of shareholders is required to fill the vacancy or vacancies; or (c) for
such longer period as the SEC may prescribe by order upon application.

     5.3   MONITORING FOR MATERIAL IRRECONCILABLE CONFLICTS.

     AVIF agrees that its Board of Directors will monitor for the existence of
any material irreconcilable conflict between the interests of the Participants
in all separate accounts of life insurance companies utilizing AVIF
("Participating Insurance Companies"), including each Account, and participants
in all qualified retirement and pension plans investing in AVIF ("Participating
Plans").  Sun Life agrees to inform the Board of Directors of AVIF of the
existence of or any potential for any such material irreconcilable conflict of
which it is aware.  The concept of a "material irreconcilable conflict" is not
defined by the 1940 Act or the rules thereunder, but the Parties recognize that
such a conflict may arise for a variety of reasons, including, without
limitation:

     (a)   an action by any state insurance or other regulatory authority;

     (b)   a change in applicable federal or state insurance, tax or securities
laws or regulations, or a public ruling, private letter ruling, no-action or
interpretative letter, or any similar action by insurance, tax or securities
regulatory authorities;

     (c)   an administrative or judicial decision in any relevant proceeding;

     (d)   the manner in which the investments of any Fund are being managed;

     (e)   a difference in voting instructions given by variable annuity
contract and variable life insurance contract Participants or by Participants of
different Participating Insurance Companies;

     (f)   a decision by a Participating Insurance Company  to disregard the
voting instructions of Participants; or

     (g)   a decision by a Participating Plan to disregard the voting
instructions of Plan participants.

     Consistent with the SEC's requirements in connection with exemptive orders
of the type referred to in Section 5.1 hereof, Sun Life will assist the Board of
Directors in carrying out its responsibilities by providing the Board of
Directors with all information reasonably necessary for the Board of Directors
to consider any issue raised, including information as to a decision by Sun Life
to disregard voting instructions of Participants. Sun Life's responsibilities in
connection with the foregoing shall be carried out with a view only to the
interests of Participants.

     5.4   CONFLICT REMEDIES.

     (a)   It is agreed that if it is determined by a majority of the members of
the Board of Directors or a majority of the Disinterested Directors that a
material irreconcilable conflict exists, Sun Life will, if it is a Participating
Insurance Company for which a material irreconcilable conflict is relevant, at
its own expense and to the extent reasonably practicable (as determined by a
majority of the Disinterested Directors), take whatever steps are necessary to
remedy or eliminate the material irreconcilable conflict, which steps may
include, but are not limited to:

           (i)    withdrawing the assets allocable to some or all of the
                  Accounts from AVIF or any Fund and reinvesting such assets in
                  a different investment medium, including another Fund of AVIF,
                  or submitting the question whether such segregation should be
                  implemented to a vote of all affected Participants and, as
                  appropriate, segregating the assets of any particular group
                  (E.G., annuity Participants, life insurance Participants or
                  all Participants) that votes in favor of such segregation, or
                  offering to the affected Participants the option of making
                  such a change; and

           (ii)   establishing a new registered investment company of the type
                  defined as a "management company" in Section 4(3) of the 1940
                  Act or a new separate account that is operated as a management
                  company.

     (b)   If the material irreconcilable conflict arises because of Sun Life's
decision to disregard Participant voting instructions and that decision
represents a minority position or would preclude a majority vote, Sun Life  may
be required, at AVIF's election, to withdraw each Account's investment in AVIF
or any Fund.  No charge or penalty will be imposed as a result of such
withdrawal.  Any such withdrawal must take place within six (6) months after
AVIF gives notice to Sun Life that this provision is being implemented, and
until such withdrawal AVIF shall continue to accept and implement orders by Sun
Life for the purchase and redemption of Shares of AVIF.

     (c)   If a material irreconcilable conflict arises because a particular
state insurance regulator's decision applicable to Sun Life conflicts with the
majority of other state regulators, then Sun Life will withdraw each Account's
investment in AVIF within six (6) months after AVIF's Board of Directors informs
Sun Life that it has determined that such decision has created a material
irreconcilable conflict, and until such withdrawal AVIF shall continue to accept
and implement orders by Sun Life for the purchase and redemption of Shares of
AVIF.  No charge or penalty will be imposed as a result of such withdrawal.


                                          13
<PAGE>

     (d)   Sun Life agrees that any remedial action taken by it in resolving any
material irreconcilable conflict will be carried out at its expense and with a
view only to the interests of Participants.

     (e)   For purposes hereof, a majority of the Disinterested Directors will
determine whether or not any proposed action adequately remedies any material
irreconcilable conflict.  In no event, however, will AVIF or any of its
affiliates be required to establish a new funding medium for any Contracts.  Sun
Life will not be required by the terms hereof to establish a new funding medium
for any Contracts if an offer to do so has been declined by vote of a majority
of Participants materially adversely affected by the material irreconcilable
conflict.

     5.5   NOTICE TO SUN LIFE.

     AVIF will promptly make known in writing to Sun Life the Board of
Directors' determination of the existence of a material irreconcilable conflict,
a description of the facts that give rise to such conflict and the implications
of such conflict.

     5.6   INFORMATION REQUESTED BY BOARD OF DIRECTORS.

     Sun Life and AVIF (or its investment adviser) will at least annually submit
to the Board of Directors of AVIF such reports, materials or data as the Board
of Directors may reasonably request so that the Board of Directors may fully
carry out the obligations imposed upon it by the provisions hereof  or  any
exemptive order granted by the SEC to permit Mixed and Shared Funding, and said
reports, materials and data will be submitted at any reasonable time deemed
appropriate by the Board of Directors.  All reports received by the Board of
Directors of potential or existing conflicts, and all Board of Directors actions
with regard to determining the existence of a conflict, notifying Participating
Insurance Companies and Participating Plans of a conflict, and determining
whether any proposed action adequately remedies a conflict, will be properly
recorded in the minutes of the Board of Directors or other appropriate records,
and such minutes or other records will be made available to the SEC upon
request.

     5.7   COMPLIANCE WITH SEC RULES.

     If, at any time during which AVIF is serving as an investment medium for
variable life insurance Contracts, 1940 Act Rules 6e-3(T) or, if applicable,
6e-2 are amended or Rule 6e-3 is adopted to provide exemptive relief with
respect to Mixed and Shared Funding, AVIF agrees that it will comply with the
terms and conditions thereof and that the terms of this Section 5 shall be
deemed modified if and only to the extent required in order also to comply with
the terms and conditions of such exemptive relief that is afforded by any of
said rules that are applicable.


     5.8   OTHER REQUIREMENTS.


                                          14

     AVIF will require that each Participating Insurance Company and
Participating Plan enter into an agreement with AVIF that contains in substance
the same provisions as are set forth in Sections 4.1(b), 4.1(d), 4.3(a), 4.4(b),
4.5(a), 5, and 10 of this Agreement.



                               SECTION 6.  TERMINATION

     6.1   EVENTS OF TERMINATION.

     Subject to Section 6.4 below, this Agreement will terminate as to a Fund:

     (a)   at the option of any party, with or without cause with respect to the
Fund, upon one (1) year's advance written notice to the other parties, or, if
later, upon receipt of any required exemptive relief from the SEC, unless
otherwise agreed to in writing by the parties; or

     (b)   at the option of AVIF upon institution of formal proceedings against
Sun Life or its affiliates by the NASD, the SEC, any state insurance regulator
or any other regulatory body regarding Sun Life's obligations under this
Agreement or related to the sale of the Contracts, the operation of each
Account, or the purchase of Shares, if, in each case, AVIF reasonably determines
that such proceedings, or the facts on which such proceedings would be based,
have a material likelihood of imposing material adverse consequences on the Fund
with respect to which the Agreement is to be terminated; or

     (c)   at the option of Sun Life upon institution of formal proceedings
against AVIF, its principal underwriter, or its investment adviser by the NASD,
the SEC, or any state insurance regulator or any other regulatory body regarding
AVIF's obligations under this Agreement or related to the operation or
management of AVIF or the purchase of AVIF Shares, if, in each case, Sun Life
reasonably determines that such proceedings, or the facts on which such
proceedings would be based, have a material likelihood of imposing material
adverse consequences on Sun Life, or the Subaccount corresponding to the Fund
with respect to which the Agreement is to be terminated; or

     (d)   at the option of any Party in the event that (i) the Fund's Shares
are not registered and, in all material respects, issued and sold in accordance
with any applicable federal or state law, or (ii) such law precludes the use of
such Shares as an underlying investment medium of the Contracts issued or to be
issued by Sun Life; or

     (e)   upon termination of the corresponding Subaccount's investment in the
Fund pursuant to Section 5 hereof; or

     (f)   at the option of Sun Life if the Fund ceases to qualify as a RIC
under Subchapter M of the Code or under successor or similar provisions, or if
Sun Life reasonably believes that the Fund may fail to so qualify; or


                                          15
<PAGE>

     (g)   at the option of Sun Life if the Fund fails to comply with Section
817(h) of the Code or with successor or similar provisions, or if Sun Life
reasonably believes that the Fund may fail to so comply; or

     (h)   at the option of AVIF if the Contracts issued by Sun Life cease to
qualify as annuity contracts or life insurance contracts under the Code (other
than by reason of the Fund's noncompliance with Section 817(h) or Subchapter M
of the Code) or if interests in an Account under the Contracts are not
registered, where required, and, in all material respects, are not issued or
sold in accordance with any applicable federal or state law; or

     (i)   upon another Party's material breach of any provision of this
Agreement; or

     (j)   at the option of Sun Life or AVIF upon receipt of any necessary
regulatory approvals and/or the vote of the Contract owners having an interest
in the account (or any Subaccount) to substitute the shares of another
investment for the corresponding AVIF Shares in accordance with the terms of the
Contracts for which those Shares had been selected to serve as the underlying
investment media.  Sun Life will give thirty (30) days' prior written notice to
AVIF of the date of any proposed vote or other action taken to replace the AVIF
Shares; or

     (k)   at the option of Sun Life, if Sun Life determines in its sole
judgment exercised in good faith, that either AVIF or AVIF's investment adviser
has suffered a material adverse change in its business, operations or financial
condition since the date of this Agreement or is the subject of material adverse
publicity which is likely to have a material adverse impact upon the business
and operations of Sun Life; or

     (l)   at the option of AVIF, if AVIF determines in its sole judgment
exercised in good faith, that Sun Life has suffered a material adverse change in
its business, operations or financial condition since the date of this Agreement
or is the subject of material adverse publicity which is likely to have a
material adverse impact upon the business and operations of AVIF.

     6.2   NOTICE REQUIREMENT FOR TERMINATION.

     No termination of this Agreement will be effective unless and until the
Party terminating this Agreement gives prior written notice to the other Party
to this Agreement of its intent to terminate, and such notice shall set forth
the basis for such termination.  Furthermore:

     (a)   in the event that any termination is based upon the provisions of
Sections 6.1(a) or  6.1(e) hereof, such prior written notice shall be given at
least six (6) months in advance of the effective date of termination unless a
shorter time is agreed to by the Parties hereto;

     (b)   in the event that any termination is based upon the provisions of
Sections 6.1(b) or  6.1(c) hereof, such prior written notice shall be given at
least ninety (90) days in advance of the effective date of termination unless a
shorter time is agreed to by the Parties hereto; and


                                          16
<PAGE>

     (c)   in the event that any termination is based upon the provisions of
Sections 6.1(d),  6.1(f),  6.1(g), 6.1(h) or 6.1(i) hereof, such prior written
notice shall be given as soon as possible within twenty-four (24) hours after
the terminating Party learns of the event causing termination to be required.

     6.3   FUNDS TO REMAIN AVAILABLE.

     Notwithstanding any termination of this Agreement, AVIF will, at the option
of Sun Life, continue to make available additional shares of the Fund pursuant
to the terms and conditions of this Agreement, for all Contracts in effect on
the effective date of termination of this Agreement (hereinafter referred to as
"Existing Contracts").  Specifically, without limitation, the owners of the
Existing Contracts will be permitted to reallocate investments in the Fund (as
in effect on such date), redeem investments in the Fund and/or invest in the
Fund upon the making of additional purchase payments under the Existing
Contracts.  The parties agree that this Section 6.3 will not apply to any
terminations under Section 5 and the effect of such terminations will be
governed by Section 5 of this Agreement.

     6.4   SURVIVAL OF WARRANTIES AND INDEMNIFICATIONS.

     All warranties and indemnifications will survive the termination of this
Agreement.

     6.5   CONTINUANCE OF AGREEMENT FOR CERTAIN PURPOSES.

     If any Party terminates this Agreement with respect to any Fund pursuant to
Sections 6.1(b), 6.1(c), 6.1(d), 6.1(f), 6.1(g), 6.1(h) or 6.1(i) hereof, this
Agreement shall nevertheless continue in effect as to any Shares of that Fund
that are outstanding as of the date of such termination (the "Initial
Termination Date").  This continuation shall extend to the earlier of the date
as of which an Account owns no Shares of the affected Fund or a date (the "Final
Termination Date") six (6) months following the Initial Termination Date, except
that Sun Life may, by written notice shorten said six (6) month period in the
case of a termination pursuant to Sections 6.1(d), 6.1(f), 6.1(g), 6.1(h) or
6.1(i).


               SECTION 7.  PARTIES TO COOPERATE RESPECTING TERMINATION

     The Parties hereto agree to cooperate and give reasonable assistance to one
another in taking all necessary and appropriate steps for the purpose of
ensuring that an Account owns no Shares of a Fund after the Final Termination
Date with respect thereto, or, in the case of a termination pursuant to Section
6.1(a), the termination date specified in the notice of termination.  Such steps
may include combining the affected Account with another Account, substituting
other mutual fund shares for those of the affected Fund, or otherwise
terminating participation by the Contracts in such Fund.


                                SECTION 8.  ASSIGNMENT


                                          17

                            SECTION 10.  VOTING PROCEDURES

     Subject to the cost allocation procedures set forth in Section 3 hereof,
Sun Life will distribute all proxy material furnished by AVIF to Participants to
whom pass-through voting privileges are required to be extended and will solicit
voting instructions from Participants. Sun Life will vote Shares in accordance
with timely instructions received from Participants.  Sun Life will vote Shares
that are (a) not attributable to Participants to whom pass-through voting
privileges are extended, or (b) attributable to Participants, but for which no
timely instructions have been received, in the same proportion as Shares for
which said instructions have been received from Participants, so long as and to
the extent that the SEC continues to interpret the 1940 Act to require pass
through voting privileges for Participants.  Neither Sun Life nor any of  its
affiliates will in any way recommend


                                          18
<PAGE>

action in connection with or oppose or interfere with the solicitation of
proxies for the Shares held for such Participants.  Sun Life reserves the right
to vote shares held in any Account in its own right, to the extent permitted by
law.  Sun Life shall be responsible for assuring that each of its Accounts
holding Shares calculates voting privileges in a manner consistent with that of
other Participating Insurance Companies in the manner required by the Mixed and
Shared Funding exemptive order obtained by AVIF.  AVIF will notify Sun Life of
any changes of interpretations or amendments to Mixed and Shared Funding
exemptive order it has obtained.  AVIF will comply with all provisions of the
1940 Act requiring voting by shareholders, and in particular, AVIF either will
provide for annual meetings (except insofar as the SEC may interpret Section 16
of the 1940 Act not to require such meetings) or will comply with Section 16(c)
of the 1940 Act (although AVIF is not one of the trusts described in Section
16(c) of that Act) as well as with Sections 16(a) and, if and when applicable,
16(b).  Further, AVIF will act in accordance with the SEC's interpretation of
the requirements of Section 16(a) with respect to periodic elections of
directors and with whatever rules the SEC may promulgate with respect thereto.


                           SECTION 11.  FOREIGN TAX CREDITS

     AVIF agrees to consult in advance with Sun Life concerning any decision to
elect or not to elect pursuant to Section 853 of the Code to pass through the
benefit of any foreign tax credits to its shareholders.


                             SECTION 12.  INDEMNIFICATION

     12.1  OF AVIF AND AIM BY SUN LIFE AND CLARENDON.

     (a)   Except to the extent provided in Sections 12.1(b) and 12.1(c), below,
Sun Life and Clarendon agree to indemnify and hold harmless AVIF, its
affiliates, and each person, if any, who controls AVIF or its affiliates within
the meaning of Section 15 of the 1933 Act and each of their respective directors
and officers, (collectively, the "Indemnified Parties" for purposes of this
Section 12.1) against any and all losses, costs, expenses, claims, damages,
liabilities (including amounts paid in settlement with the written consent of
Sun Life and Clarendon) or actions in respect thereof (including, to the extent
reasonable, legal and other expenses), to which the Indemnified Parties may
become subject under any statute, regulation, at common law or otherwise;
PROVIDED, the Account owns shares of the Fund and  insofar as such losses,
costs, expenses, claims, damages, liabilities or actions:

             (i)  arise out of or are based upon any untrue statement or alleged
                  untrue statement of any material fact contained in any
                  Account's 1933 Act registration statement, any Account
                  Prospectus, the Contracts, or sales literature or advertising
                  for the Contracts (or any amendment or supplement to any of
                  the foregoing), or arise out of or are based upon the omission
                  or the alleged omission to state therein a material fact
                  required to be stated therein or necessary to make the
                  statements therein not misleading; PROVIDED, that this
                  agreement to indemnify shall not

<PAGE>

                  apply as to any Indemnified Party if such statement or
                  omission or such alleged statement or omission was made in
                  reliance upon and in conformity with information furnished to
                  Sun Life or Clarendon by or on behalf of AVIF or AIM for use
                  in any Account's 1933 Act registration statement, any Account
                  Prospectus, the Contracts, or sales literature or advertising
                  or otherwise for use in connection with the sale of Contracts
                  or Shares (or any amendment or supplement to any of the
                  foregoing); or

            (ii)  arise out of or as a result of any other statements or
                  representations (other than statements or representations
                  contained in AVIF's 1933 Act registration statement, AVIF
                  Prospectus, sales literature or advertising of AVIF, or any
                  amendment or supplement to any of the foregoing, not supplied
                  for use therein by or on behalf of Sun Life, Clarendon or
                  their respective affiliates  and on which such persons have
                  reasonably relied) or the negligent, illegal or fraudulent
                  conduct of Sun Life, Clarendon or their respective affiliates
                  or persons under their control (including, without limitation,
                  their employees and "Associated Persons," as that term is
                  defined in paragraph (m) of Article I of the NASD's By-Laws),
                  in connection with the sale or distribution of the Contracts
                  or Shares; or

           (iii)  arise out of or are based upon any untrue statement or alleged
                  untrue statement of any material fact contained in AVIF's 1933
                  Act registration statement, AVIF Prospectus, sales literature
                  or advertising of AVIF, or any amendment or supplement to any
                  of the foregoing, or the omission or alleged omission to state
                  therein a material fact required to be stated therein or
                  necessary to make the statements therein not misleading if
                  such a statement or omission was made in reliance upon and in
                  conformity with information furnished to AVIF or its
                  affiliates by or on behalf of Sun Life, Clarendon or their
                  respective affiliates for use in AVIF's 1933 Act registration
                  statement, AVIF Prospectus, sales literature or advertising of
                  AVIF, or any amendment or supplement to any of the foregoing;
                  or

            (iv)  arise as a result of any failure by Sun Life or Clarendon to
                  perform the obligations, provide the services and furnish the
                  materials required of them under the terms of this Agreement,
                  or any material breach of any representation and/or warranty
                  made by Sun Life or Clarendon in this Agreement or arise out
                  of or result from any other material breach of this Agreement
                  by Sun Life or Clarendon; or

             (v)  arise as a result of failure by the Contracts issued by Sun
                  Life to qualify as annuity contracts or life insurance
                  contracts under the Code, otherwise than by reason of any
                  Fund's failure to comply with Subchapter M or Section 817(h)
                  of the Code.

     (b)   Neither Sun Life nor Clarendon shall be liable under this Section
12.1 with respect to any losses, costs, expenses, claims, damages, liabilities
or actions to which an Indemnified Party


                                          20
<PAGE>

would otherwise be subject by reason of willful misfeasance, bad faith, or 
gross negligence in the performance by that Indemnified Party of its duties 
or by reason of that Indemnified Party's reckless disregard of obligations or 
duties (i) under this Agreement, or (ii) to AVIF.

     (c)   Neither Sun Life nor Clarendon shall be liable under this Section
12.1 with respect to any action against an Indemnified Party unless AVIF or AIM
shall have notified Sun Life and Clarendon in writing within a reasonable time
after the summons or other first legal process giving information of the nature
of the action shall have been served upon such Indemnified Party (or after such
Indemnified Party shall have received notice of such service on any designated
agent), but failure to notify Sun Life and Clarendon of any such action shall
not relieve Sun Life and Clarendon from any liability which they may have to the
Indemnified Party against whom such action is brought otherwise than on account
of this Section 12.1.  Except as otherwise provided herein, in case any such
action is brought against an Indemnified Party, Sun Life and Clarendon shall be
entitled to participate, at their own expense, in the defense of such action and
also shall be entitled to assume the defense thereof, with counsel approved by
the Indemnified Party named in the action, which approval shall not be
unreasonably withheld.  After notice from Sun Life or Clarendon to such
Indemnified Party of Sun Life's or Clarendon's election to assume the defense
thereof, the Indemnified Party will cooperate fully with Sun Life and Clarendon
and shall bear the fees and expenses of any additional counsel retained by it,
and neither Sun Life nor Clarendon will be liable to such Indemnified Party
under this Agreement for any legal or other expenses subsequently incurred by
such Indemnified Party independently in connection with the defense thereof,
other than reasonable costs of investigation.

     12.2  OF SUN LIFE AND CLARENDON BY AVIF AND AIM.

     (a)   Except to the extent provided in Sections 12.2(c), 12.2(d) and
12.2(e), below, AVIF  and AIM agree to indemnify and hold harmless Sun Life,
Clarendon, their respective affiliates, and each person, if any, who controls
Sun Life, Clarendon or their respective affiliates within the meaning of Section
15 of the 1933 Act and each of their respective directors and officers,
(collectively, the "Indemnified Parties" for purposes of this Section 12.2)
against any and all losses, costs, expenses, claims, damages, liabilities
(including amounts paid in settlement with the written consent of AVIF and/or
AIM ) or actions in respect thereof (including, to the extent reasonable, legal
and other expenses), to which the Indemnified Parties may become subject under
any statute, regulation, at common law, or otherwise; PROVIDED, the Account owns
shares of the Fund and  insofar as such losses, costs, expenses, claims,
damages, liabilities or actions:

             (i)  arise out of or are based upon any untrue statement or alleged
                  untrue statement of any material fact contained in AVIF's 1933
                  Act registration statement, AVIF Prospectus or sales
                  literature or advertising of AVIF (or any amendment or
                  supplement to any of the foregoing), or arise out of or are
                  based upon the omission or the alleged omission to state
                  therein a material fact required to be stated therein or
                  necessary to make the statements therein not misleading;
                  PROVIDED, that this agreement to indemnify shall not apply as
                  to any Indemnified Party if such statement or omission or such
                  alleged statement or omission was made in reliance upon and in
                  conformity with information furnished to AVIF


                                          21

                  or its affiliates by or on behalf of Sun Life, Clarendon or
                  their respective affiliates for use in AVIF's 1933 Act
                  registration statement, AVIF Prospectus, or in sales
                  literature or advertising or otherwise for use in connection
                  with the sale of Contracts or Shares (or any amendment or
                  supplement to any of the foregoing); or

            (ii)  arise out of or as a result of any other statements or
                  representations (other than statements or representations
                  contained in any Account's 1933 Act registration statement,
                  any Account Prospectus, sales literature or advertising for
                  the Contracts, or any amendment or supplement to any of the
                  foregoing, not supplied for use therein by or on behalf of
                  AVIF or AIM or their affiliates and on which such persons have
                  reasonably relied) or the negligent, illegal or fraudulent
                  conduct of AVIF or AIM or their affiliates or persons under
                  its control (including, without limitation, their employees
                  and "Associated Persons" as that term is defined in Section
                  (n) of Article I of the NASD By-Laws), in connection with the
                  sale or distribution of AVIF Shares; or

           (iii)  arise out of or are based upon any untrue statement or alleged
                  untrue statement of any material fact contained in any
                  Account's 1933 Act registration statement, any Account
                  Prospectus, sales literature or advertising covering the
                  Contracts, or any amendment or supplement to any of the
                  foregoing, or the omission or alleged omission to state
                  therein a material fact required to be stated therein or
                  necessary to make the statements therein not misleading, if
                  such statement or omission was made in reliance upon and in
                  conformity with information furnished to Sun Life, Clarendon
                  or their respective affiliates by or on behalf of AVIF or AIM
                  for use in any Account's 1933 Act registration statement, any
                  Account Prospectus, sales literature or advertising covering
                  the Contracts, or any amendment or supplement to any of the
                  foregoing; or

            (iv)  arise as a result of any failure by AVIF to perform the
                  obligations, provide the services and furnish the materials
                  required of it under the terms of this Agreement, or any
                  material breach of any representation and/or warranty made by
                  AVIF in this Agreement or arise out of or result from any
                  other material breach of this Agreement by AVIF.

     (b)   Except to the extent provided in Sections 12.2(c), 12.2(d) and
12.2(e) hereof, AVIF  and AIM agree to indemnify and hold harmless the
Indemnified Parties from and against any and all losses, claims, damages,
liabilities (including amounts paid in settlement thereof with, the written
consent of AVIF and/or AIM) or actions in respect thereof (including, to the
extent reasonable, legal and other expenses) to which the Indemnified Parties
may become subject directly or indirectly under any statute, at common law or
otherwise, insofar as such losses, claims, damages, liabilities or actions
directly or indirectly result from or arise out of  the failure of any Fund to
operate as a regulated investment company in compliance with (i) Subchapter M of
the Code and regulations thereunder, or (ii) Section 817(h) of the Code and
regulations thereunder, including, without limitation, any income taxes and
related interest and penalties, rescission charges, liability under


                                          22
<PAGE>

state law to Participants asserting liability against Sun Life pursuant to the
Contracts, the costs of any ruling and closing agreement or other settlement
with the IRS, and the cost of any substitution by Sun Life of Shares of another
investment company or portfolio for those of any adversely affected Fund as a
funding medium for each Account that Sun Life reasonably deems necessary or
appropriate as a result of the noncompliance.

     (c)   Neither AVIF nor AIM shall be liable under this Section 12.2 with
respect to any losses, costs, expenses, claims, damages, liabilities or actions
to which an Indemnified Party would otherwise be subject by reason of willful
misfeasance, bad faith, or gross negligence in the performance by that
Indemnified Party of its duties or by reason of such Indemnified Party's
reckless disregard of its obligations and duties (i) under this Agreement, or
(ii) to Sun Life, Clarendon, each Account or Participants.

     (d)   Neither AVIF nor AIM shall be liable under this Section 12.2 with
respect to any action against an Indemnified Party unless the Indemnified Party
shall have notified AVIF and/or AIM in writing within a reasonable time after
the summons or other first legal process giving information of the nature of the
action shall have been served upon such Indemnified Party (or after such
Indemnified Party shall have received notice of such service on any designated
agent), but failure to notify AVIF or AIM of any such action shall not relieve
AVIF or AIM from any liability which it may have to the Indemnified Party
against whom such action is brought otherwise than on account of this Section
12.2.  Except as otherwise provided herein, in case any such action is brought
against an Indemnified Party, AVIF and/or AIM will be entitled to participate,
at its own expense, in the defense of such action and also shall be entitled to
assume the defense thereof (which shall include, without limitation, the conduct
of any ruling request and closing agreement or other settlement proceeding with
the IRS), with counsel approved by the Indemnified Party named in the action,
which approval shall not be unreasonably withheld.  After notice from AVIF
and/or AIM to such Indemnified Party of AVIF's or AIM's election to assume the
defense thereof, the Indemnified Party will cooperate fully with AVIF and AIM
and shall bear the fees and expenses of any additional counsel retained by it,
and AVIF will not be liable to such Indemnified Party under this Agreement for
any legal or other expenses subsequently incurred by such Indemnified Party
independently in connection with the defense thereof, other than reasonable
costs of investigation.

     (e)   In no event shall either AVIF or AIM be liable under the
indemnification provisions contained in this Agreement to any individual or
entity, including, without limitation, Sun Life, Clarendon or any other
Participating Insurance Company or any Participant, with respect to any losses,
claims, damages, liabilities or expenses that arise out of or result from (i) a
breach of any representation, warranty, and/or covenant made by Sun Life or
Clarendon hereunder or by any Participating Insurance Company under an agreement
containing substantially similar representations, warranties and covenants; (ii)
the failure by Sun Life or any Participating Insurance Company to maintain its
segregated asset account (which invests in any Fund) as a legally and validly
established segregated asset account under applicable state law and as a duly
registered unit investment trust under the provisions of the 1940 Act (unless
exempt therefrom); or (iii) the failure by Sun Life or any Participating
Insurance Company to maintain its variable annuity or life insurance contracts
(with respect to which any Fund serves as an underlying funding vehicle) as
annuity contracts or life insurance contracts under applicable provisions of the
Code.

     12.3  EFFECT OF NOTICE.

     Any notice given by the indemnifying Party to an Indemnified Party referred
to in Sections 12.1(c) or 12.2(d) above of participation in or control of any
action by the indemnifying Party will in no event be deemed to be an admission
by the indemnifying Party of liability, culpability or responsibility, and the
indemnifying Party will remain free to contest liability with respect to the
claim among the Parties or otherwise.



     12.4  SUCCESSORS.

     A successor by law of any Party shall be entitled to the benefits of the

                             SECTION 18.  CONFIDENTIALITY

     AVIF acknowledges that the identities of the customers of Sun Life or any
of its affiliates (collectively, the "Sun Life Protected Parties" for purposes
of this Section 18), information maintained regarding those customers, and all
computer programs and procedures or other information developed by the Sun Life
Protected Parties or any of their employees or agents in connection with Sun
Life's performance of its duties under this Agreement are the valuable property
of the Sun Life Protected Parties.  AVIF agrees that if it comes into possession
of any list or compilation of the identities of or other information about the
Sun Life Protected Parties' customers, or any other information or property of
the Sun Life Protected Parties, other than such information as may be
independently developed or compiled by AVIF from information supplied to it by
the Sun Life Protected Parties' customers who also maintain accounts directly
with AVIF, AVIF will hold such information or property in confidence and refrain
from using, disclosing or distributing any of such information or other property
except: (a) with Sun Life's prior written consent; or (b) as required by law or
judicial process.  Sun Life acknowledges that the identities of the customers of
AVIF or any of its affiliates (collectively, the "AVIF Protected Parties" for
purposes of this Section 18), information maintained regarding those customers,
and all computer programs and procedures or other information developed by the
AVIF Protected Parties or any of  their employees or agents in connection with
AVIF's performance of its duties under this Agreement are the valuable property
of the AVIF Protected Parties.  Sun Life agrees that if it comes into possession
of any list or compilation of the identities of or other information about the
AVIF Protected Parties' customers or any other information or property of the
AVIF Protected Parties, other than such information as may be independently
developed or compiled by Sun Life from information supplied to it by the AVIF
Protected Parties' customers who also maintain accounts directly with Sun Life,
Sun Life will hold such information or property in confidence and refrain from
using, disclosing or distributing any of such information or other property
except: (a) with AVIF's prior written consent; or (b) as required by law or
judicial process.  Each party acknowledges that any breach of the agreements in
this Section 18 would result in immediate and irreparable harm to the other
parties for which there would be no adequate remedy at law and agree that in the
event of such a breach, the other parties will be entitled to equitable relief
by way of temporary and permanent injunctions, as well as such other relief as
any court of competent jurisdiction deems appropriate.


                        SECTION 19.  TRADEMARKS AND FUND NAMES

     (a)   A I M Management Group Inc. ("AIM" or "licensor"), an affiliate of
AVIF,  owns all right, title and interest in and to the name, trademark and
service mark "AIM" and such other tradenames, trademarks and service marks as
may be set forth on Schedule B, as amended from time to time by written notice
from AIM to Sun Life (the "AIM licensed marks" or the "licensor's licensed
marks") and is authorized to use and to license other persons to use such marks.
Sun Life and its affiliates are hereby granted a non-exclusive license to use
the AIM licensed marks in


                                          25
<PAGE>

connection with Sun Life's performance of the services contemplated under this
Agreement, subject to the terms and conditions set forth in this Section 19.

     (b)   The grant of license to Sun Life and its affiliates ( the "licensee")
shall terminate automatically upon termination of this Agreement.  Upon
automatic termination, the licensee shall cease to use the licensor's licensed
marks, except that Sun Life shall have the right to continue to service any
outstanding Contracts bearing any of the AIM licensed marks.  Upon AIM's
elective termination of this license, Sun Life and its affiliates shall
immediately cease to issue any new annuity or life insurance contracts bearing
any of the AIM licensed marks and shall likewise cease any activity which
suggests that it has any right under any of the AIM licensed marks or that it
has any association with AIM, except that Sun Life shall have the right to
continue to service outstanding Contracts bearing any of the AIM licensed marks
and to use AIM licensed marks in such materials as may be necessary for filing
with any regulatory authority where required by law or regulation or to enable
Sun Life to quote performance to existing Contract owners.

     (c)   The licensee shall obtain the prior written approval of the licensor
for the public release by such licensee of any materials bearing the licensor's
licensed marks.  The licensor's approvals shall not be unreasonably withheld and
may be obtained in connection with approval of sales materials as provided in
Section 4.5(b) hereof (i.e., approvals obtained under Section 4.5 hereof shall
be deemed approval pursuant to this Section 19).

     (d)   During the term of this grant of license, a licensor may request that
a licensee submit samples of any materials bearing any of the licensor's
licensed marks which were previously approved by the licensor but, due to
changed circumstances, the licensor may wish to reconsider.  If, on
reconsideration, or on initial review, respectively, any such samples fail to
meet with the written approval of the licensor, then the licensee shall
immediately cease distributing such disapproved materials, upon receiving notice
of such failure by the licensor. The licensor's approval shall not be
unreasonably withheld, and the licensor, when requesting reconsideration of a
prior approval, shall assume the reasonable expenses of withdrawing and
replacing such disapproved materials.  The licensee shall obtain the prior
written approval of the licensor for the use of any new materials developed to
replace the disapproved materials, in the manner set forth above.

     (e)   The licensee hereunder: (i) acknowledges and stipulates, based upon
the representations of the licensor set forth herein and without making any
independent inquiry thereof, that, to the best of the knowledge of the licensee,
the licensor's licensed marks are valid and enforceable trademarks and/or
service marks; (ii) acknowledges and stipulates that such licensee does not own
the licensor's licensed marks and claims no rights therein other than as a
licensee under this Agreement; (iii) agrees never to contend otherwise in legal
proceedings or in other circumstances; and (iv) acknowledges and agrees that the
use of the licensor's licensed marks pursuant to this grant of license shall
inure to the benefit of the licensor.


                          SECTION 20.  PARTIES TO COOPERATE

     Each party to this Agreement will cooperate with each other party and all
appropriate governmental authorities (including, without limitation, the SEC,
the NASD and state insurance


                                          26

regulators) and will permit each other and such authorities reasonable access to
its books and records (including copies thereof)  in connection with any
investigation or inquiry relating to this Agreement or the transactions
contemplated hereby.


                    SECTION 21.  ACCESS TO INFORMATION BY SUN LIFE

     During ordinary business hours, AVIF shall afford Sun Life, directly or
through its authorized representatives, reasonable access to all files, books,
records and other materials of AVIF (except for confidential or proprietary
materials) which directly relate to transactions arising in connection with this
Agreement and to make available appropriate personnel familiar with such items
for the purpose of explaining the form and content of such items.  This Section
21 shall survive the termination of this Agreement.

Accounts on those days on which the Fund calculates its net asset value pursuant

person, or suspend or terminate the offering of shares of any Portfolio if such
action is required by law or by regulatory authorities having jurisdiction or
is, in the sole discretion of the Board acting in good faith and in light of
their fiduciary duties under federal and any applicable state laws, necessary in
the best interest of the shareholders of such Portfolio.

     1.3.  The Fund and the Adviser agree that shares of the Fund will be sold

full or fractional shares of the Fund held by the Company, executing such
requests on a daily basis at the net asset value next computed after receipt by
the Fund or its designee of the request for redemption.  For purposes of this
Section 1.5, the Company shall be the designee of the Fund for receipt of
requests for redemption from each Account and receipt by such designee shall

the next Business Day after an order to purchase Fund shares is made in
accordance with the provisions of Section 1.1 hereof.  Payment shall be in

Shares ordered from the Fund will be recorded in an appropriate title for each
Account or the appropriate subaccount of each Account.

     1.9.  The Fund shall furnish same day notice (by wire or telephone,
followed by written confirmation) to the Company of any income dividends or
capital gain distributions payable on the Fund's shares.  The Company hereby
elects to receive all such income dividends and capital gain distributions as

Company reserves the right to revoke


                                          4

available to the Company on a daily basis as soon as reasonably practicable

available by 7:00 p.m. Eastern time.

with the money and/or securities of the Fund are and shall continue to be at all
times covered by a blanket fidelity bond or similar coverage for the benefit of
the Fund, in an amount not less than the minimal coverage as required currently
by entities subject to the requirements of Rule 17g-1 of the 1940 Act or related
provisions as may be promulgated from time to time.  The aforesaid Bond shall
include coverage for larceny and embezzlement and shall be issued by a reputable

such documentation (including a final "camera ready" or diskette copy of the new
prospectus as set in type at the Fund's expense) and other assistance as is
reasonably necessary in order for the Company once each year (or more frequently
if the prospectus for the


                                          7

Fund is amended) to have the prospectus for the Contracts and the Fund's

such Statement free of charge to the Company and to any owner of a Contract or
prospective owner who requests such Statement.

     3.3.  The Fund, at its expense, shall provide the Company with copies of
its proxy material, reports to shareholders, and other communications to

               (i)    solicit voting instructions from Contract owners;

               (ii)   vote the Fund shares in accordance with instructions
                      received from Contract owners; and

               (iii)  vote Fund shares for which no instructions have been
                      received in the same proportion as Fund shares of such
                      Portfolio for which instructions have been received:

so long as and to the extent that the Commission continues to interpret the 1940
Act to require pass-through voting privileges for owners of Variable Insurance
Products.  The Company reserves the right to vote Fund shares held in any
segregated asset account in its own right, to the extent permitted by law.
Participating Insurance Companies shall be responsible for assuring that each of
their separate accounts participating in the Fund calculates voting privileges
in a manner consistent with this Section and with each other.

817(h) of the Code and Treasury Regulation Section 1.817-5, relating to the
diversification requirements for variable annuity, endowment, or life insurance
contracts, to the extent such


                                          11
<PAGE>

requirements apply to the Portfolio's investments pursuant to Treasury
Regulation Section 1.817-5(f), and any amendments or other modifications to such
Section or Regulations.


ARTICLE VII.  POTENTIAL CONFLICTS

     7.1.  The Board will monitor the Fund for the existence of any material
irreconcilable conflict among the interests of the contract owners of all
separate accounts investing in the Fund and determine what action is to be
taken.  An irreconcilable material conflict may arise for a variety of reasons,
including:  (a) an action by any state insurance regulatory authority; (b) a
change in applicable federal or state insurance, tax or securities laws or
regulations, or a public ruling, private letter ruling, no-action or
interpretive letter, or any similar action by insurance, tax, or securities
regulatory authorities; (c) an administrative or judicial decision in any
relevant proceeding; (d) the manner in which the investments of any Portfolio
are being managed; (e) a difference in voting instructions given by variable
annuity contract owners, variable life insurance contract owners and Plan
trustees; (f) a decision by an insurer to disregard the voting instructions of
contract owners; or (g) if applicable, a decision by a Qualified Plan to
disregard the voting instructions of Plan participants.  The Board shall
promptly inform the Company if it determines that an irreconcilable material
conflict exists and the implications thereof.

     7.2.  The Company will report any potential or existing conflicts of which
it is aware to the Board.  The Company and the Adviser will assist the Board in
carrying out its responsibilities under the Mixed and Shared Funding Exemptive
Order by providing the Board with all information reasonably necessary for the
Board to consider any issues raised.  This includes, but is not limited to, an
obligation by the Company to inform the Board whenever contract owner voting
instructions are disregarded.

     7.3.  If it is determined by a majority of the Board, or a majority of its
disinterested trustees that a material irreconcilable conflict exists, the
Company and


                                          12
<PAGE>

other Participating Insurance Companies shall, at their expense and to the
extent reasonably practicable (as determined by a majority of the disinterested
trustees), take whatever steps are necessary to remedy or eliminate the
irreconcilable material conflict, up to and including:  (1) withdrawing the
assets allocable to some or all of the separate accounts from the Fund or any
Portfolio and reinvesting such assets in a different investment medium,
including (but not limited to) another Portfolio of the Fund, or submitting the
question whether such segregation should be implemented to a vote of all
affected Contract owners and, as appropriate, segregating the assets of any
appropriate group (I.E., annuity contract owners, life insurance contract
owners, or variable contract owners of one or more Participating Insurance
Companies) that votes in favor of such segregation, or offering to the affected
contract owners the option of making such a change; and (2) establishing a new
registered management investment company or series thereof or managed separate
account.

     7.4.  If a material irreconcilable conflict arises because of a decision by
the Company to disregard contract owner voting instructions and that decision
represents a minority position or would preclude a majority vote, the Company
may be required, at the Fund's election, to withdraw the affected Account's
investment in the Fund and terminate this Agreement with respect to such
Account; provided, however that such withdrawal and termination shall be limited
to the extent required by the foregoing material irreconcilable conflict as
determined by a majority of the disinterested members of the Board.  No charge
or penalty will be imposed as a result of the withdrawal.  Any such withdrawal
and termination must take place within six (6) months after the Fund gives
written notice that this provision is being implemented, and until the end of
that six (6) month period the Adviser and Fund shall continue to accept and
implement orders by the Company for the purchase (and redemption) of shares of
the Fund.


                                          13
<PAGE>

     7.5.  If a material irreconcilable conflict arises because a particular
state insurance regulator's decision applicable to the Company conflicts with
the majority of other state regulators, then the Company will withdraw the
affected Account's investment in the Fund and terminate this Agreement with
respect to such Account within six (6) months after the Board informs the
Company in writing that it has determined that such decision has created an
irreconcilable material conflict; provided, however, that such withdrawal and
termination shall be limited to the extent required by the foregoing material
irreconcilable conflict as determined by a majority of the disinterested members
of the Board.  Until the end of the foregoing six (6) month period, the Adviser
and Fund shall continue to accept and implement orders by the Company for the
purchase (and redemption) of shares of the Fund.

     7.6.  For purposes of Sections 7.3 through 7.6 of this Agreement, a
majority of the disinterested members of the Board shall determine whether any
proposed action adequately remedies any irreconcilable material conflict, but in
no event will the Fund be required to establish a new funding medium for the
Contracts.  The Company shall not be required by Section 7.3 to establish a new
funding medium for the contracts if an offer to do so has been (a) declined by
vote of a majority of Contract owners materially adversely affected by the
irreconcilable material conflict or (b) pursuant to governing Qualified Plan
documents and applicable law, the Qualified Plan makes the decision without a
vote of its participants.  In the event that the Board determines that any
proposed action does not adequately remedy any irreconcilable material conflict,
then the Company will withdraw the Account's investment in the Fund and
terminate this Agreement within six (6) months after the Board informs the
Company in writing of the foregoing determination, provided, however, that such
withdrawal and termination shall be limited to the extent required by any such
material irreconcilable conflict as determined by a majority of the
disinterested members of the Board.

     8.1(a).  The Company agrees to indemnify and hold harmless the Fund and
each of its directors and officers and each person, if any, who controls the
Fund or the Adviser within the meaning of Section 15 of the 1933 Act
(collectively, the "Indemnified Parties" for purposes of this Section 8.1)
against any and all losses, claims, damages, liabilities (including amounts paid
in settlement with the written consent of the Company) or litigation (including
legal and other expenses), to which the Indemnified Parties may become subject
under any statute, regulation, at common law or otherwise, insofar as such
losses, claims, damages, liabilities or expenses (or actions in respect thereof)
or settlements are related to the sale or acquisition of the Fund's shares or
the Contracts and:

          (i)    arise out of or are based upon any untrue statements or alleged
     untrue statements of any material fact contained in the Registration
     Statement or prospectus for the Contract or contained in the Contracts or
     sales literature for the Contracts (or any amendment or supplement to any
     of the foregoing), or arise out of or are based upon the omission or the
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading,
     provided that this agreement to indemnify shall not apply as to any
     Indemnified Party if such statement or omission or such alleged statement
     or omission was made in reliance upon and in conformity with information
     furnished to the Company by or on behalf of the Fund for use in the
     Registration Statement or prospectus for the Contracts or in the Contracts
     or sales literature (or any amendment or supplement) or otherwise for use
     in connection with the sale of the Contracts or Fund shares; or

          (ii)   arise out of or as a result of statements or representations
     (other than statements or representations contained in the Registration
     Statement,


                                          15
<PAGE>

     prospectus or sales literature of the Fund not supplied by the Company, or
     persons under its control) or wrongful conduct of the Company or persons
     under its control, with respect to the sale or distribution of the
     Contracts or Fund Shares; or

          (iii)  arise out of any untrue statement or alleged untrue statement
     of a material fact contained in a Registration Statement, prospectus, or
     sales literature of the Fund or any amendment thereof or supplement thereto
     or the omission or alleged omission to state therein a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading if such a statement or omission was made in reliance upon
     information furnished to the Fund by or on behalf of the Company; or

          (iv)   arise as a result of any failure by the Company to provide the
     services and furnish the materials under the terms of this Agreement; or

          (v)    arise out of or result from any material breach of any
     representation and/or warranty made by the Company in this Agreement or
     arise out of or result from any other material breach of this Agreement by
     the Company, as limited by and in accordance with the provisions of
     Sections 8.1(b) and 8.1(c) hereof.

     8.1(b).  The Company shall not be liable under this indemnification
provision with respect to any losses, claims, damages, liabilities or litigation
incurred or assessed against an Indemnified Party as such may arise from such
Indemnified Party's willful misfeasance, bad faith, or gross negligence in the
performance of such Indemnified Party's duties or by reason of such Indemnified
Party's reckless disregard of obligations or duties under this Agreement or to
the Fund, whichever is applicable.

     8.1(c).  The Company shall not be liable under this indemnification
provision with respect to any claim made against an Indemnified Party unless
such Indemnified Party shall have notified the Company in writing within a
reasonable time after the


                                          16
<PAGE>

summons or other first legal process giving information of the nature of the
claim shall have been served upon such Indemnified Party (or after such
Indemnified Party shall have received notice of such service on any designated
agent), but failure to notify the Company of any such claim shall not relieve
the Company from any liability which it may have to the Indemnified Party
against whom such action is brought otherwise than on account of this
indemnification provision.  In case any such action is brought against the
Indemnified Parties, the Company shall be entitled to participate, at its own
expense, in the defense of such action.  The Company also shall be entitled to
assume the defense thereof, with counsel satisfactory to the party named in the
action.  After notice from the Company to such party of the Company's election
to assume the defense thereof, the Indemnified Party shall bear the fees and
expenses of any additional counsel retained by it, and the Company will not be
liable to such party under this Agreement for any legal or other expenses
subsequently incurred by such party independently in connection with the defense
thereof other than reasonable costs of investigation.

     8.1(d).  The Indemnified Parties will promptly notify the Company of the
commencement of any litigation or proceedings against them in connection with
the issuance or sale of the Fund Shares or the Contracts or the operations of
the Fund.

     8.2.  INDEMNIFICATION BY THE ADVISER

     8.2(a).  The Adviser agrees to indemnify and hold harmless the Company and
each of its directors and officers and each person, if any, who controls the
Company within the meaning of Section 15 of the 1933 Act (collectively, the
"Indemnified Parties" for purposes of this Section 8.2) against any and all
losses, claims, damages, liabilities (including amounts paid in settlement with
the written consent of the Adviser) or litigation (including legal and other
expenses) to which the Indemnified Parties may become subject under any statute,
at common law or otherwise, insofar as such losses,


                                          17
<PAGE>

claims, damages, liabilities or expenses (or actions in respect thereof) or
settlements are related to the sale or acquisition of the Fund's shares or the
Contracts and:

          (i)    arise out of or are based upon any untrue statement or alleged
     untrue statement of any material fact contained in the Registration
     Statement or prospectus or sales literature of the Fund (or any amendment
     or supplement to any of the foregoing), or arise out of or are based upon
     the omission or the alleged omission to state therein a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading, provided that this agreement to indemnify shall not apply
     as to any Indemnified Party if such statement or omission or such alleged
     statement or omission was made in reliance upon and in conformity with
     information furnished to the Adviser or Fund by or on behalf of the Company
     specifically for use in the Registration Statement or prospectus for the
     Fund or in sales literature (or any amendment or supplement) or otherwise
     specifically for use in connection with the sale of the Contracts or Fund
     shares: or

          (ii)   arise out of or as a result of statements or representations
     (other than statements or representations contained in the Registration
     Statement, prospectus or sales literature for the Contracts not supplied by
     the Adviser or persons under its control) or wrongful conduct of the Fund
     or Adviser or persons under their control, with respect to the sale or
     distribution of the Contracts or Fund shares; or

          (iii)  arise out of any untrue statement or alleged untrue statement
     of a material fact contained in a Registration Statement, prospectus or
     sales literature covering the Contracts, or any amendment thereof or
     supplement thereto, or the omission or alleged omission to state therein a
     material fact required to be stated therein or necessary to make the
     statement or statements therein not misleading, if such statement or
     omission was made in reliance upon and in conformity with


                                          18
<PAGE>

     information furnished to the Company by or on behalf of the Fund
     specifically for inclusion therein; or

          (iv)   arise as a result of any failure by the Fund to provide the
     services and furnish the materials under the terms of this Agreement
     (including a failure of any Portfolio, whether unintentional or in good
     faith or otherwise, to invest in a manner that complies with the
     diversification requirements specified in Article VI of this Agreement); or

          (v)    arise out of or result from any material breach of any
     representation and/or warranty made by the Adviser in this Agreement or
     arise out of or result from any other material breach of this Agreement by
     the Adviser; as limited by and in accordance with the provisions of
     Sections 8.2(b) and 8.2(c) hereof.

     8.2(b).  The Adviser shall not be liable under this indemnification
provision with respect to any losses, claims, damages, liabilities or litigation
to which an Indemnified Party would otherwise be subject by reason of such
Indemnified Party's willful misfeasance, bad faith, or gross negligence in the
performance of such Indemnified Party's duties or by reason of such Indemnified
Party's reckless disregard of obligations and duties under this Agreement or to
each Company or Account, whichever, is applicable.

     8.2(c).  The Adviser shall not be liable under this indemnification
provision with respect to any claim made against an Indemnified Party unless
such Indemnified Party shall have notified the Adviser in writing within a
reasonable time after the summons or other first legal process giving
information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify the Adviser of any
such claim shall not relieve the Adviser from any liability which it may have to
the Indemnified Party against whom such action is brought otherwise than on
account of this indemnification provision.  In case any such action is brought
against the


                                          19
<PAGE>

Indemnified Parties, the Adviser will be entitled to participate, at its own
expense, in the defense thereof.  The Adviser also shall be entitled to assume
the defense thereof with counsel satisfactory to the party named in the action.
After notice from the Adviser to such party of the Adviser's election to assume
the defense thereof, the Indemnified Party shall bear the fees and expenses of
any additional counsel retained by it, and the Adviser will not be liable to
such party under this Agreement for any legal or other expenses subsequently
incurred by such party independently in connection with the defense thereof
other than reasonable costs of investigation.

     8.2(d).  The Company agrees promptly to notify the Adviser of the
commencement of any litigation or proceedings against it or any of its officers
or directors in connection with the issuance or sale of the Contracts or the
operation of each Account.

of the Contracts as determined by the Company within ten (10) days of notice by
Company to Fund of such fact; or

against the Company by the NASD, the Commission, the insurance or securities

suffered a material adverse change in its business, operations or financial

ARTICLE I.  SALE OF FUND SHARES

     1.1    The Underwriter agrees to sell to the Company those shares of the
Designated Portfolios which the Account orders, executing such orders on a daily
basis at the net asset value next computed after receipt by the Fund or its
designee of the order for the shares of the Designated Portfolios.

     1.2    The Fund agrees to make shares of the Designated Portfolios
available for purchase at the applicable net asset value per share by the
Company and the Account on those days on which the Fund calculates its net asset
value pursuant to rules of the SEC, and the Fund shall use its best efforts to
calculate such net asset value on each day which the New York Stock Exchange is
open for trading.  Notwithstanding the foregoing, the Board of Directors of the
Fund (hereinafter the "Board") may refuse to sell shares of any Designated
Portfolio to any person, or suspend or terminate the offering of shares of any
Designated Portfolio if such action is required by law or by regulatory
authorities having jurisdiction, or is, in the sole discretion of the Board

<PAGE>

                                         -3-

acting in good faith and in light of their fiduciary duties under federal and
any applicable state laws, necessary in the best interests of the shareholders
of such Designated Portfolio.

     1.3    The Fund and the Underwriter agree that shares of the Fund will be
sold only to Participating Insurance Companies and their separate accounts.  No
shares of any Designated Portfolios will be sold to the general public.  The
Fund and the Underwriter will not sell Fund shares to any insurance company or
separate account unless an agreement containing provisions substantially the
same as Articles I, III and VII of this Agreement is in effect to govern such
sales.

     1.4    The Fund agrees to redeem, on the Company's request, any full or
fractional shares of the Designated Portfolios held by the Company, executing
such requests on a daily basis at the net asset value next computed after
receipt by the Fund or its designee of the request for redemption, except that
the Fund reserves the right to suspend the right of redemption or postpone the
date of payment or satisfaction upon redemption consistent with Section 22(e) of
the 1940 Act and any sales thereunder, and in accordance with the procedures and
policies of the Fund as described in the then current prospectus.

     1.5    For purposes of Sections 1.1 and 1.4, the Company shall be the
designee of the Fund for receipt of purchase and redemption orders from the
Account, and receipt by such designee shall constitute receipt by the Fund;
provided that the Company receives the order by 4:00 p.m. Baltimore time and the
Fund receives notice of such order by 9:30 a.m. Baltimore time on the next
following Business Day.  "Business Day" shall mean any day on which the New York
Stock Exchange is open for trading and on which the Fund calculates its net
asset value pursuant to the rules of the SEC.

     1.6    The Company agrees to purchase and redeem the shares of each
Designated Portfolio offered by the then current prospectus of the Fund and in
accordance with the provisions of such prospectus.

     1.7    The Company shall pay for Fund shares one Business Day after receipt
of an order to purchase Fund shares is made in accordance with the provisions of
Section 1.5 hereof.  Payment shall be in federal funds transmitted by wire by
3:00 p.m. Baltimore time.  If payment in Federal Funds for any purchase is not
received or is received by the Fund after 3:00 p.m. Baltimore time on such
Business Day, the Company shall promptly, upon the Fund's request, reimburse the
Fund for any charges, costs, fees, interest or other expenses incurred by the
Fund in connection with any advances to, or borrowings or overdrafts by, the
Fund, or any similar expenses incurred by the Fund, as a result of portfolio
transactions effected by the Fund based upon such purchase request.  For
purposes of Section 2.8 and 2.9 hereof, upon receipt by the Fund of the federal
funds so wired, such funds shall cease to be the responsibility of the Company
and shall become the responsibility of the Fund.

     1.8    Issuance and transfer of the Fund's shares will be by book entry
only.  Stock certificates will not be issued to the Company or any Account.
Shares ordered from the Fund will be recorded in an appropriate title for each
Account or the appropriate subaccount of each Account.

     1.9    The Fund shall furnish same day notice (by wire or telephone,
followed by written confirmation) to the Company of any income, dividends or
capital gain distributions payable on the Designated Portfolios' shares.  The
Company hereby elects to receive all such income, dividends, and capital gain
distributions as are payable on Designated Portfolio shares in additional shares
of that Portfolio.  The Company reserves the right to revoke this election and
to receive all such income dividends and capital gain distributions in cash.
The Fund shall notify the Company of the number of shares so issued as payment
of such dividends and distributions.

     1.10   The Fund shall make the net asset value per share for each
Designated Portfolio available to the Company on a daily basis as soon as
reasonably practical after the net asset value per share is calculated (normally
by 6:30 p.m. Baltimore time) and shall use its best efforts to make such net
asset value per share available by 7 p.m. Baltimore time.  If the net asset
value is materially incorrect through no fault of the Company, the Company on
behalf of each Account, shall be entitled to an adjustment to the number of
shares purchased or redeemed to reflect the correct net asset value in
accordance with Fund procedures.  Any material error in the net asset value
shall be reported to the Company promptly upon discovery.  Any administrative or
other costs or losses incurred for correcting underlying Contract owner accounts
shall be at Company's expense.

     1.11   The Parties hereto acknowledge that the arrangement contemplated by
this Agreement is not exclusive; the Fund's shares may be sold to other
insurance companies (subject to Section 1.3 and Article VI hereof) and the cash
value of the Contracts may be invested in other investment companies.

bonding company.

ARTICLE III.  PROSPECTUSES, STATEMENTS OF ADDITIONAL INFORMATION, AND PROXY
STATEMENTS; VOTING

     3.1    The Underwriter shall provide the Company (at the Company's expense)
with as many copies of the Fund's current prospectus (describing only the
Designated Portfolios listed on Schedule A) as the Company may reasonably
request.  If requested by the Company in lieu thereof, the Fund shall provide
such documentation (including a final copy of the new prospectus as set in type
or on a diskette, at the Fund's expense) and other assistance as is reasonably
necessary in order for the Company (at the Company's expense) once each year (or
more frequently if the prospectus for the Fund is amended) to have the
prospectus for the Contracts and the Fund's prospectus printed together in one
document (such printing to be at the Company's expense).

     3.2    The Fund's prospectus shall state that the current Statement of
Additional Information ("SAI") for the Fund is available from the Company (or,
in the Fund's discretion, from the Fund), and the Underwriter (or the Fund), at
its expense, shall print, or otherwise reproduce, and provide a copy of such SAI
free of charge to the Company for itself and for any owner of a Contract who
requests such SAI.

     3.3    The Fund, at its expense, shall provide the Company with copies of
its proxy material, reports to shareholders, and other communications to
shareholders in such quantity as the Company shall reasonably require for
distributing to Contract owners in the Fund.  The Underwriter (at the Company's
expense) shall provide the Company with copies of the Fund's annual and
semi-annual reports to shareholders in such quantity as the Company shall
reasonably request for use in connection with offering the Variable Contracts
issued by the Company.  If requested by the Company in lieu thereof, the
Underwriter shall provide such documentation (which may include a final copy of
the Fund's annual and semi-annual reports as set in type or on diskette) and
other assistance as is reasonably necessary in order for the Company (at the
Company's expense) to print such shareholder communications for distribution to
Contract owners.

     3.4    The Company shall:

            (i)    solicit voting instructions from Contract owners;

            (ii)   vote the Fund shares in accordance with instructions received
                   from Contract owners; and

            (iii)  vote Fund shares for which no instructions have been received
                   in the same proportion as Fund shares of such Designated
                   Portfolio for which instructions have been received,

so long as and to the extent that the SEC continues to interpret the 1940 Act to
require pass-through voting privileges for variable contract owners or to the
extent otherwise required by law.  The Company reserves the right to vote Fund
shares held in any segregated asset account in its own right, to the extent
permitted by law.

<PAGE>

                                         -7-

     3.5    Participating Insurance Companies shall be responsible for assuring
that each of their separate accounts participating in a Designated Portfolio
calculates voting privileges as required by the Shared Funding Exemptive Order
and consistent with any reasonable standards that the Fund may adopt.

     3.6    The Fund will comply with all provisions of the 1940 Act requiring
voting by shareholders, and in particular the Fund will either provide for
annual meetings or comply with Section 16(c) of the 1940 Act (although the Fund
is not one of the trusts described in Section 16(c) of that Act) as well as with
Sections 16(a) and, if and when applicable, 16(b).  Further, the Fund will act
in accordance with the SEC's interpretation of the requirements of Section 16(a)
with respect to periodic elections of directors or trustees and with whatever
rules the SEC may promulgate with respect thereto.

ARTICLE IV.  SALES MATERIAL AND INFORMATION

     4.1    The Company shall furnish, or shall cause to be furnished, to the
Fund or its designee, each piece of sales literature or other promotional
material that the Company develops or uses and in which the Fund (or a Portfolio
thereof) or the Adviser or the Underwriter is named, at least ten calendar days

reasonably object to such use within ten calendar days after receipt of such

the continued use of such material, and no such material shall be used if the
Fund or its designee so object.

     4.2    The Company shall not give any information or make any
representations or statements on behalf of the Fund or concerning the Fund in
connection with the sale of the Contracts other than the information or
representations contained in the registration statement or prospectus or SAI for
the Fund shares, as such registration statement and prospectus or SAI may be
amended or supplemented from time to time, or in reports or proxy statements for
the Fund, or in sales literature or other promotional material approved by the
Fund or its designee or by the Underwriter, except with the permission of the
Fund or the Underwriter or the designee of either.

     4.3    The Fund, Underwriter, or its designee shall furnish, or shall cause
to be furnished, to the Company, each piece of sales literature or other
promotional material in which the Company, and/or its Account, is named at least
ten calendar days prior to its use.  No such material shall be used if the
Company reasonably objects to such use within ten calendar days after receipt of

continued use of such material and no such material shall be used if the Company
so objects.

     4.4.   The Fund and the Underwriter shall not give any information or make
any representations on behalf of the Company or concerning the Company, the
Account, or the Contracts other than the information or representations
contained in a registration statement, prospectus, or SAI for the Contracts, as
such registration statement, prospectus or SAI may be amended or supplemented
from time to time, or in published reports for the Account which are in the
public domain or approved by the Company for distribution to Contract owners, or
in sales literature or other promotional material approved by the Company or its
designee, except with the permission of the Company.

<PAGE>

                                         -8-

     4.5    The Fund will provide to the Company at least one complete copy of
all registration statements, prospectuses, SAIs, reports, proxy statements,
sales literature and other promotional materials, applications for exemptions,
requests for no-action letters, and all amendments to any of the above, that
relate to the Fund or its shares, within a reasonable time after the filing of
such document(s) with the SEC or other regulatory authorities.

     4.6    The Company will provide to the Fund at least one complete copy of
all registration statements, prospectuses, SAIs, reports, solicitations for
voting instructions, sales literature and other promotional materials,

other promotional materials" includes, but is not limited to, any of the
following that refer to the Fund or any affiliate of the Fund:  advertisements
(such as material published, or designed for use in, a newspaper, magazine, or
other periodical, radio, television, telephone or tape recording, videotape
display, signs or billboards, motion pictures, or other public media), sales
literature (I.E., any written communication distributed or made generally

advertisement, sales literature, or published article), educational or training
materials or other communications distributed or made generally available to
some or all agents or employees, and registration statements, prospectuses,
SAIs, shareholder reports, proxy materials, and any other communications
distributed or made generally available with regard to the Funds.

ARTICLE V.  FEES AND EXPENSES

     5.1    The Fund and the Underwriter shall pay no fee or other compensation
to the Company under this Agreement, except that if the Fund or any Portfolio
adopts and implements a plan pursuant to Rule 12b-1 to finance distribution
expenses, then the Underwriter may make payments to the Company or to the
underwriter for the Contracts if and in amounts agreed to by the Underwriter in
writing, and such payments will be made out of existing fees otherwise payable
to the Underwriter, past profits of the Underwriter, or other resources
available to the Underwriter.  No such payments shall be made directly by the
Fund.  Currently, no such payments are contemplated.

     5.2    All expenses incident to performance by the Fund under this
Agreement shall be paid by the Fund, except as otherwise provided herein.  The
Fund shall see to it that all its shares are registered and authorized for
issuance in accordance with applicable federal law and, if and to the extent
deemed advisable by the Fund, in accordance with applicable state laws prior to
their sale.  The Fund shall bear the expenses for the cost of registration and
qualification of the Fund's shares, preparation and filing of the Fund's
prospectus and registration statement, proxy materials and reports, setting the

shares.

<PAGE>

                                         -9-

     5.3    The Company shall bear the expenses of printing the Fund's
prospectus (in accordance with 3.1) and of distributing the Fund's prospectus,
proxy materials, and reports to Contract owners and prospective Contract owners.

ARTICLE VI.  DIVERSIFICATION AND QUALIFICATION

     6.1    The Fund will invest the assets of each Designated Portfolio in such
a manner as to ensure that the Contracts will be treated as annuity, endowment,
or life insurance contracts, whichever is appropriate, under the Internal
Revenue Code of 1986, as amended (the "Code") and the regulations issued
thereunder (or any successor provisions).  Without limiting the scope of the
foregoing, each Designated Portfolio of the Fund will comply with Section 817(h)
of the Code and Treasury Regulation '1.817-5, and any Treasury interpretations
thereof, relating to the diversification requirements for variable annuity,
endowment, or life insurance contracts, and any amendments or other
modifications or successor provisions to such Section or Regulations.  In the
event of a breach of this Article VI by the Fund, it will take all reasonable
steps (a) to notify the Company of such breach and (b) to adequately diversify
the Fund so as to achieve compliance within the grace period afforded by
Regulation 817.5.

     6.2    The Fund represents that each Designated Portfolio is or will be
qualified as a Regulated Investment Company under Subchapter M of the Code, and
that it will make every effort to maintain such qualification (under Subchapter
M or any successor or similar provisions) and that it will notify the Company
immediately upon having a reasonable basis for believing that it has ceased to
so qualify or that it might not so qualify in the future.

     6.3    The Company represents that the Contracts are currently, and at the
time of issuance shall be, treated as life insurance, endowment contracts, or
annuity insurance contracts, under applicable provisions of the Code, and that
it will make every effort to maintain such treatment, and that it will notify
the Fund and the Underwriter immediately upon having a reasonable basis for
believing the Contracts have ceased to be so treated or that they might not be
so treated in the future.  The Company agrees that any prospectus offering a
contract that is a "modified endowment contract" as that term is defined in
Section 7702A of the Code (or any successor or similar provision), shall
identify such contract as a modified endowment contract.

ARTICLE VII.  POTENTIAL CONFLICTS.

     7.1    The Board will monitor the Fund for the existence of any material
irreconcilable conflict between the interests of the contract owners of all
separate accounts investing in the Fund.  An irreconcilable material conflict
may arise for a variety of reasons, including:  (a) an action by any state
insurance regulatory authority; (b) a change in applicable federal or state
insurance, tax, or securities laws or regulations, or a public ruling, private
letter ruling, no-action or interpretative letter, or any similar action by
insurance, tax, or securities regulatory authorities; (c) an administrative or
judicial decision in any relevant proceeding; (d) the manner in which the
investments of any Portfolio are being managed; (e) a difference in voting
instructions given by variable annuity contract and variable life insurance
contract owners; or (f) a decision by an insurer to disregard the voting
instructions of contract owners.  The Board shall promptly inform the Company if
it determines that an irreconcilable material conflict exists and the
implications thereof.

<PAGE>

                                         -10-

     7.2.   The Company will report any potential or existing conflicts of which
it is aware to the Board.  The Company will assist the Board in carrying out its
responsibilities under the Shared Funding Exemptive Order, by providing the
Board with all information reasonably necessary for the Board to consider any
issues raised.  This includes, but is not limited to, an obligation by the
Company to inform the Board whenever Contract owner voting instructions are
disregarded.

     7.3    If it is determined by a majority of the Board, or a majority of its
disinterested members, that a material irreconcilable conflict exists, the
Company and other Participating Insurance Companies shall, at their expense and
to the extent reasonably practicable (as determined by a majority of the
disinterested Board members), take whatever steps are necessary to remedy or
eliminate the irreconcilable material conflict, up to and including:  (1),
withdrawing the assets allocable to some or all of the separate accounts from
the Fund or any Portfolio and reinvesting such assets in a different investment
medium, including (but not limited to) another Portfolio of the Fund, or
submitting the question whether such segregation should be implemented to a vote
of all affected contract owners and, as appropriate, segregating the assets of
any appropriate group (I.E., annuity contract owners, life insurance contract
owners, or variable contract owners of one or more Participating Insurance
Companies) that votes in favor of such segregation, or offering to the affected
contract owners the option of making such a change; and (2), establishing a new
registered management investment company or managed separate account.

     7.4    If a material irreconcilable conflict arises because of a decision
by the Company to disregard contract owner voting instructions and that decision
represents a minority position or would preclude a majority vote, the Company
may be required, at the Fund's election, to withdraw the affected Account's
investment in the Fund and terminate this Agreement with respect to such Account
provided, however, that such withdrawal and termination shall be limited to the
extent required by the foregoing material irreconcilable conflict as determined
by a majority of the disinterested members of the Board.  Any such withdrawal
and termination must take place within six (6) months after the Fund gives
written notice that this provision is being implemented, and until the end of
that six month period the Fund shall continue to accept and implement orders by
the Company for the purchase (and redemption) of shares of the Fund.

     7.5    If a material irreconcilable conflict arises because a particular
state insurance regulator's decision applicable to the Company conflicts with
the majority of other state regulators, then the Company will withdraw the
affected Account's investment in the Fund and terminate this Agreement with
respect to such Account within six months after the Board informs the Company in
writing that it has determined that such decision has created an irreconcilable
material conflict; provided, however, that such withdrawal and termination shall
be limited to the extent required by the foregoing material irreconcilable
conflict as determined by a majority of the disinterested members of the Board.
Until the end of the foregoing six month period, the Fund shall continue to
accept and implement orders by the company for the purchase (and redemption) of
shares of the Fund.

     7.6    For purposes of Section 7.3 through 7.6 of this Agreement, a
majority of the disinterested members of the Board shall determine whether any
proposed action adequately remedies any irreconcilable material conflict, but in
no event will the Fund be required to

<PAGE>

                                         -11-

establish a new funding medium for the Contracts.  The Company shall not be
required by Section 7.3 to establish a new funding medium for the Contract if an
offer to do so has been declined by vote of a majority of Contract owners
materially adversely affected by the irreconcilable material conflict.  In the
event that the Board determines that any proposed action does not adequately
remedy any irreconcilable material conflict, then the Company will withdraw the
Account's investment in the Fund and terminate this Agreement within six (6)
months after the Board informs the Company in writing of the foregoing
determination; provided, however, that such withdrawal and termination shall be
limited to the extent required by any such material irreconcilable conflict as
determined by a majority of the disinterested members of the Board.

     7.7    If and to the extent Rule 6e-2 and Rule 6e-3(T) are amended, or
Rule 6e-3 is adopted, to provide exemptive relief from any provision of the 1940
Act or the rules promulgated thereunder with respect to mixed or shared funding
(as defined in the Shared Funding Exemptive Order) on terms and conditions
materially different from those contained in the Shared Funding Exemptive Order,
then (a) the Fund and/or the Participating Insurance Companies, as appropriate,
shall take such steps as may be necessary to comply with Rules 6e-2 and 6e-3(T),
as amended, and Rule 6e-3, as adopted, to the extent such rules are applicable;
and (b) Sections 3.4, 3.5, 3.6, 7.1., 7.2, 7.3, 7.4, and 7.5 of this Agreement
shall continue in effect only to the extent that terms and conditions
substantially identical to such Sections are contained in such Rule(s) as so
amended or adopted.

ARTICLE VIII.  INDEMNIFICATION

     8.1    INDEMNIFICATION BY THE COMPANY

            8.1(a).  The Company agrees to indemnify and hold harmless the Fund
and the Underwriter and each of their officers and directors and each person, if
any, who controls the Fund or the Underwriter within the meaning of Section 15
of the 1933 Act (collectively, the "Indemnified Parties" for purposes of this
Section 8.1) against any and all losses, claims, damages, liabilities (including
amounts paid in settlement with the written consent of the Company) or
litigation (including legal and other expenses), to which the Indemnified
Parties may become subject under any statute or regulation, at common law or
otherwise, insofar as such losses, claims, damages, liabilities or expenses (or
actions in respect thereof) or settlements are related to the sale or
acquisition of the Fund's shares or the Contracts and:

            (i)    arise out of or are based upon any untrue statements or
                   alleged untrue statements of any material fact contained in
                   the Registration Statement, prospectus, or statement of
                   additional information ("SAI") for the Contracts or contained
                   in the Contracts or sales literature or other promotional
                   material for the Contracts (or any amendment or supplement to
                   any of the foregoing), or arise out of or are based upon the
                   omission or the alleged omission to state therein a material
                   fact required to be stated therein or necessary to make the
                   statements therein not misleading, provided that this
                   agreement to indemnify shall not apply as to any Indemnified
                   Party if such statement or omission or such alleged statement
                   or omission was made in reliance upon and in conformity with
                   information

<PAGE>

                                         -12-

                   furnished to the Company by or on behalf of the Fund for use
                   in the Registration Statement, prospectus or SAI for the
                   Contracts or in the Contracts or sales literature or other
                   promotional material (or any amendment or supplement) or
                   otherwise for use in connection with the sale of the
                   Contracts or Fund shares; or

            (ii)   arise out of or as a result of statements or representations
                   (other than statements or representations contained in the
                   Registration Statement, prospectus or sales literature or
                   other promotional material of the Fund not supplied by the
                   Company or persons under its control) or wrongful conduct of
                   the Company or persons under its authorization or control,
                   with respect to the sale or distribution of the Contracts or
                   Fund Shares; or

            (iii)  arise out of any untrue statement or alleged untrue statement
                   of a material fact contained in a Registration Statement,
                   prospectus, SAI, or sales literature or other promotional
                   material of the Fund or any amendment thereof or supplement
                   thereto or the omission or alleged omission to state therein
                   a material fact required to be stated therein or necessary to
                   make the statements therein not misleading if such a
                   statement or omission was made in reliance upon information
                   furnished to the Fund by or on behalf of the Company; or

            (iv)   arise as a result of any material failure by the Company to
                   provide the services and furnish the materials under the
                   terms of this Agreement (including a failure, whether
                   unintentional or in good faith or otherwise, to comply with
                   the qualification requirements specified in Article VI of
                   this Agreement); or

            (v)    arise out of or result from any material breach of any
                   representation and/or warranty made by the Company in this
                   Agreement or arise out of or result from any other material
                   breach of this Agreement by the Company,

as limited by and in accordance with the provisions of Sections 8.1(b) and
8.1(c) hereof.

            8.1(b).  The Company shall not be liable under this indemnification
provision with respect to any losses, claims, damages, liabilities or litigation
to which an Indemnified Party would otherwise be subject by reason of such
Indemnified Party's willful misfeasance, bad faith, or gross negligence in the
performance of such Indemnified Party's duties or by reason of such Indemnified
Party's reckless disregard of its obligations or duties under this Agreement.

            8.1(c).  The Company shall not be liable under this indemnification
provision with respect to any claim made against an Indemnified Party unless
such Indemnified Party shall have notified the Company in writing within a
reasonable time after the summons or other first legal process giving
information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify the Company of any
such claim shall not relieve the Company from any liability which it may have to
the Indemnified Party against whom such

                                         -13-

action is brought otherwise than on account of this indemnification provision.
In case any such action is brought against an Indemnified Party, the Company
shall be entitled to participate, at its own expense, in the defense of such
action.  The Company also shall be entitled to assume the defense thereof, with
counsel satisfactory to the party named in the action and to settle the claim at
its own expense; provided, however, that no such settlement shall, without the
Indemnified Parties' written consent, include any factual stipulation referring
to the Indemnified Parties or their conduct.  After notice from the Company to
such party of the Company's election to assume the defense thereof, the
Indemnified Party shall bear the fees and expenses of any additional counsel
retained by it, and the Company will not be liable to such party under this
Agreement for any legal or other expenses subsequently incurred by such party
independently in connection with the defense thereof other than reasonable costs
of investigation.

            8.1(d).  The Indemnified Parties will promptly notify the Company of
the commencement of any litigation or proceedings against them in connection
with the issuance or sale of the Fund Shares or the Contracts or the operation
of the Fund.

     8.2    INDEMNIFICATION BY THE UNDERWRITER

            8.2(a).  The Underwriter agrees to indemnify and hold harmless the
Company and each of it directors and officers and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act
(collectively, the "Indemnified Parties" for purposes of this Section 8.2)
against any and all losses, claims, damages, liabilities (including amounts paid
in settlement with the written consent of the Underwriter) or litigation
(including legal and other expenses) to which the Indemnified Parties may become
subject under any statute or regulation, at common law or otherwise, insofar as
such losses, claims, damages, liabilities or expenses (or actions in respect
thereof) or settlements are related to the sale or acquisition of the Fund's
shares or the Contracts; and

                   (i)    arise out of or are based upon any untrue statement or
                          alleged untrue statement of any material fact
                          contained in the Registration Statement or prospectus
                          or SAI or sales literature or other promotional
                          material of the Fund (or any amendment or supplement
                          to any of the foregoing), or arise out of or are based
                          upon the omission or the alleged omission to state
                          therein a material fact required to be stated therein
                          or necessary to make the statements therein not
                          misleading, provided that this agreement to indemnify
                          shall not apply as to any Indemnified Party if such
                          statement or omission or such alleged statement or
                          omission was made in reliance upon and in conformity
                          with information furnished to the Underwriter or Fund
                          by or on behalf of the Company for use in the
                          Registration Statement or prospectus for the Fund or
                          in sales literature or other promotional material (or
                          any amendment or supplement) or otherwise for use in
                          connection with the sale of the Contracts or Fund
                          shares; or

                   (ii)   arise out of or as a result of statements or
                          representations (other than statements or
                          representations contained in the Registration

                          promotional material for the Contracts not supplied by
                          the Underwriter or persons under its control) or
                          wrongful conduct of the Fund or Underwriter or persons
                          under their control, with respect to the sale or
                          distribution of the Contracts or Fund shares; or

                   (iii)  arise out of any untrue statement or alleged untrue
                          statement of a material fact contained in a
                          Registration Statement, prospectus, SAI, or sales
                          literature or other promotional material of the
                          Contracts, or any amendment thereof or supplement
                          thereto, or the omission or alleged omission to state
                          therein a material fact required to be stated therein
                          or necessary to make the statement or statements
                          therein not misleading, if such statement or omission
                          was made in reliance upon information furnished to the
                          Company by or on behalf of the Fund; or

                   (iv)   arise as a result of any material failure by the Fund
                          to provide the services and furnish the materials
                          under the terms of this Agreement (including a
                          failure, whether unintentional or in good faith or
                          otherwise, to comply with the diversification and
                          other qualification requirements specified in Article
                          VI of this Agreement); or

                   (v)    arise out of or result from any material breach of any
                          representation and/or warranty made by the Underwriter

                          Underwriter;

as limited by and in accordance with the provisions of Sections 8.2(b) and
8.2(c) hereof.

            8.2(b).  The Underwriter shall not be liable under this
indemnification provision with respect to any losses, claims, damages,
liabilities or litigation to which an Indemnified Party would otherwise be
subject by reason of such Indemnified Party's willful misfeasance, bad faith, or
gross negligence in the performance or such Indemnified Party's duties or by
reason of such Indemnified Party's reckless disregard of obligations and duties
under this Agreement or to the Company or the Account, whichever is applicable.

            8.2(c).  The Underwriter shall not be liable under this
indemnification provision with respect to any claim made against an Indemnified
Party unless such Indemnified Party shall have notified the Underwriter in
writing within a reasonable time after the summons or other first legal process
giving information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify the Underwriter of
any such claim shall not relieve the Underwriter from any liability which it may
have to the Indemnified Party against whom such action is brought otherwise than
on account of this indemnification provision.  In case any such action is
brought against the Indemnified Party, the Underwriter will be entitled to
participate, at its own expense, in the defense thereof.  The Underwriter also
shall be entitled to

                                         -15-

assume the defense thereof, with counsel satisfactory to the party named in the
action and to settle the claim at its own expense; provided, however, that no
such settlement shall, without the Indemnified Parties' written consent, include
any factual stipulation referring to the Indemnified Parties or their conduct.
After notice from the Underwriter to such party of the Underwriter's election to
assume the defense thereof, the Indemnified Party shall bear the fees and
expenses of any additional counsel retained by it, and the Underwriter will not
be liable to such party under this Agreement for any legal or other expenses
subsequently incurred by such party independently in connection with the defense
thereof other than reasonable costs of investigation.

            8.2(d).  The Company agrees promptly to notify the Underwriter of
the commencement of any litigation or proceedings against it or any of its
officers or directors in connection with the issuance or sale of the Contracts
or the operation of the Account.

     8.3    INDEMNIFICATION BY THE FUND

            8.3(a).  The Fund agrees to indemnify and hold harmless the Company
and each of its directors and officers and each person, if any, who controls the
Company within the meaning of Section 15 of the 1933 Act (collectively, the
"Indemnified Parties" for purposes of this Section 8.3) against any and all
losses, claims, expenses, damages, liabilities (including amounts paid in
settlement with the written consent of the Fund) or litigation (including legal
and other expenses) to which the Indemnified Parties may be required to pay or
may become subject under any statute or regulation, at common law or otherwise,
insofar as such losses, claims, expenses, damages, liabilities or expenses (or
actions in respect thereof) or settlements, are related to the operations of the
Fund and:

                   (i)    arise as a result of any material failure by the Fund
                          to provide the services and furnish the materials
                          under the terms of this Agreement (including a

                          other material breach of this Agreement by the Fund;

as limited by and in accordance with the provisions of Sections 8.3(b) and
8.3(c) hereof.

            8.3(b).  The Fund shall not be liable under this indemnification
provision with respect to any losses, claims, damages, liabilities or litigation
to which an Indemnified Party would otherwise be subject by reason of such
Indemnified Party's willful misfeasance, bad faith, or gross negligence in the
performance of such Indemnified Party's duties or by reason of such Indemnified
Party's reckless disregard of obligations and duties under this Agreement or to

respect to any claim made against an Indemnified Party unless such Indemnified
Party shall have notified the Fund in writing within a reasonable time after the
summons or other first legal process giving information of the nature of the
claim shall have been served upon such Indemnified Party (or after such
indemnified Party shall have received notice of such service on any designated
agent), but failure to notify the Fund of any such claim shall not relieve the

                   or all Designated Portfolios, by six (6) months' advance
                   written notice delivered to the other parties; or

            (b)    termination by the Company by written notice to the Fund and
                   the Underwriter with respect to any Designated Portfolio
                   based upon the Company's determination that shares of the
                   Fund are not reasonably available to meet the requirements of
                   the Contracts; provided that such termination shall apply
                   only to the Designated Portfolio not reasonably

<PAGE>

                                         -17-

                   available; or

            (c)    termination by the Company by written notice to the Fund and
                   the Underwriter in the event any of the Designated
                   Portfolio's shares are not registered, issued or sold in
                   accordance with applicable state and/or federal law or such
                   law precludes the use of such shares as the underlying
                   investment media of the Contracts issued or to be issued by
                   the Company; or

            (d)    termination by the Fund or Underwriter in the event that
                   formal administrative proceedings are instituted against the

                   like official of any state or any other regulatory body

                   related to the sale of the Contracts, the operation of any
                   Account, or the purchase of the Fund shares; provided,
                   however, that the Fund or Underwriter determines in its sole
                   judgment exercised in good faith, that any such
                   administrative proceedings will have a material adverse
                   effect upon the ability of the Company to perform its
                   obligations under this Agreement; or

                   insurance department or any other regulatory body; provided,
                   however, that the Company determines in its sole judgment
                   exercised in good faith, that any such administrative
                   proceedings will have a material adverse effect upon the
                   ability of the Fund or Underwriter to perform its obligations
                   under this Agreement; or

            (f)    termination by the Company by written notice to the Fund and
                   the Underwriter with respect to any Designated Portfolio in

                   a Regulated Investment Company under Subchapter M or fails to
                   comply with the Section 817(h) diversification requirements
                   specified in Article VI hereof, or if the Company reasonably
                   believes that such Designated Portfolio may fail to so
                   qualify or comply; or

            (g)    termination by the Fund or Underwriter by written notice to
                   the Company in the event that the Contracts fail to meet the

                   Fund or Underwriter reasonably believes that such Contracts
                   may fail to so qualify; or

            (h)    termination by either the Fund or the Underwriter by written
                   notice to the Company, if either one or both of the Fund or
                   the Underwriter respectively, shall determine, in their sole
                   judgment exercised in good faith, that the Company has
                   suffered a material adverse change in its business,
                   operations, financial condition, or prospects since the date
                   of this Agreement or is the subject of material adverse
                   publicity; or

            (i)    termination by the Company by written notice to the Fund and
                   the Underwriter, if the Company shall determine, in its sole
                   judgment exercised in good faith, that the Fund or the
                   Underwriter has suffered a material adverse change in its
                   business, operations, financial condition or prospects since
                   the date of this Agreement or is the subject of material
                   adverse publicity.

     10.2   EFFECT OF TERMINATION.  Notwithstanding any termination of this
Agreement, the Fund and the Underwriter shall, at the option of the Company,
continue to make available additional shares of the Fund pursuant to the terms
and conditions of this Agreement, for all Contracts in effect on the effective
date of termination of this Agreement (hereinafter referred to as "Existing
Contracts").  Specifically, the owners of the Existing Contracts may be
permitted to reallocate investments in the Fund, redeem investments in the Fund
and/or invest in the Fund upon the making of additional purchase payments under
the Existing Contracts.  The parties agree that this Section 10.2 shall not
apply to any termination under Article VII and the effect of such Article VII
termination shall be governed by Article VII of this Agreement.  The parties
further agree that this Section 10.2 shall not apply to any termination under
Section 10.1(g) of this Agreement.

     10.3   The Company shall not redeem Fund shares attributable to the
Contracts (as opposed to Fund shares attributable to the Company's assets held
in the Account) except (i) as necessary to implement Contract owner initiated or
approved transactions, (ii) as required by state and/or federal laws or
regulations or judicial or other legal precedent of general application
(hereinafter referred to as a "Legally Required Redemption"), or (iii) pursuant
to the terms of a substitution order issued by the SEC pursuant to Section 26(b)
of the 1940 Act.  Upon request, the Company will promptly furnish to the Fund
and the Underwriter the opinion of counsel for the Company (which counsel shall
be reasonably satisfactory to the Fund and the Underwriter) to the effect that
any redemption pursuant to clause (ii) above is a Legally Required Redemption.
Furthermore, except in cases where permitted under the terms of the Contracts,
the Company shall not prevent Contract owners from allocating payments to a
Portfolio that was otherwise available under the Contracts without first giving
the Fund or the Underwriter 30 days notice of its intention to do so.

     10.4   Notwithstanding any termination of this Agreement, each party's
obligation under Article VIII to indemnify the other parties shall survive.

mail to the other party at the address of such party set forth below or at such
other address as such party may from time to time specify in writing to the

addresses and other confidential information without the express written consent
of the affected party until such time as such information may come into the
public domain.

     12.3   The captions in this Agreement are included for convenience of
reference only and in no way define or delineate any of the provisions hereof or
otherwise affect their construction or effect.

                                         -20-

each of which taken together shall constitute one and the same instrument.

     12.5   If any provision of this Agreement shall be held or made invalid by
a court decision, statute, rule or otherwise, the remainder of the Agreement
shall not be affected thereby.

     12.6   Each party hereto shall cooperate with each other party and all
appropriate governmental authorities (including without limitation the SEC, the

reasonable access to its books and records in connection with any investigation
or inquiry relating to this Agreement or the transactions contemplated hereby.
Notwithstanding the generality of the foregoing, each party hereto further
agrees to furnish the Delaware Insurance Commissioner with any information or
reports in connection with services provided under this Agreement which such

operations of the Company are being conducted in a manner consistent with
Delaware variable annuity laws and regulations and any other applicable law or
regulations.

     12.7   The rights, remedies and obligations contained in this Agreement are
cumulative and are in addition to any and all rights, remedies, and obligations,
at law or in equity, which the parties hereto are entitled to under state and
federal laws.

     12.8   This Agreement or any of the rights and obligations hereunder may
not be assigned by any party without the prior written consent of all parties
hereto.

                   accounting principles) and annual report (prepared under
                   generally accepted accounting principles ("GAAP"), if any),
                   as soon as practical and in any event within 90 days after
                   the end of each fiscal year.

            (b)    the Company's quarterly statements (statutory) (and GAAP, if
                   any), as soon as practical and in any event within 45 days
                   after the end of each quarterly period.

furnished to the Company cumulative and annualized performance data for the Fund
within 10 days of the close of each month, which performance data shall include,

                          [Letterhead of Sun Life of Canada]


April 30, 1999

Gentlemen:

In my capacity as Product Officer for Sun Life Assurance Company of Canada, I
have provided actuarial advice concerning:  (a) the preparation of a
registration statement for Sun Life of Canada (U.S.) Variable Account G filed on
Form S-6 with the Securities Exchange Commission under the Securities Act of
1933 (the "Registration Statement") regarding the offer and sale of flexible
premium variable universal life insurance policies (the "Policies"); and (b) the
preparation of policy forms for the Policies described in the Registration
Statement.

It is my professional opinion that:

     The illustrations of cash surrender values, account values, death benefits
     and accumulated premiums in the Appendix to the prospectus contained in the
     Registration Statement, are based on the assumptions stated in the
     illustrations, and are consistent with the provisions of the Policies.  The
     rate structure of the Policies has not been designed so as to make the
     relationship between premiums and benefits, as shown in the illustrations,
     appear to be more favorable to prospective purchasers of Policies aged 45
     in the rate classes illustrated than to prospective purchasers of Policies,
     for males or females, at other ages.

I hereby consent to the filing of this opinion as an exhibit to the Registration
Statement and to the use of my name under the heading "Experts" in the
prospectus.

                                   Very truly yours,


                                   /s/ John E. Coleman

                                   John E. Coleman, FSA, MAAA
                                   Product Officer
